iSHARES^® ASIA 50 ETF

Ticker: AIA

Stock Exchange: NASDAQ

Investment Objective

The iShares Asia 50 ETF (the “Fund”) seeks to track the investment results of an index composed of 50 of the largest Asian equities.

Fees and Expenses

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

Annual Fund Operating Expenses (ongoing expenses that you pay each year as a percentage of the value of your investments)
Management Fees	Distribution and Service (12b-1) Fees	Other Expenses	Total Annual Fund Operating Expenses
0.50%	None	None	0.50%

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year		3 Years		5 Years		10 Years
$51		$160		$280		$628

S-1

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 16% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P Asia 50^TM (the “Underlying Index”), which is a total float-adjusted, market capitalization-weighted index that is designed to measure the performance of the 50 leading companies listed in four Asian countries or regions: Hong Kong, Singapore, South Korea and Taiwan, as determined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). As of March 31, 2018, the Underlying Index had a total market capitalization of approximately $2.41 trillion. The Underlying Index includes large-capitalization blue-chip companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the financials and information technology industries or sectors. The components of the Underlying Index are likely to change over time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and

does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to that of an applicable underlying index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of an applicable underlying index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally will invest at least 90% of its assets in the component securities of the Underlying Index and in investments that have economic characteristics that are substantially identical to the component securities of the Underlying Index (i.e., depositary receipts representing securities of the Underlying Index) and may invest up to 10% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, as well as in securities not

S-2

included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

The Underlying Index is a product of SPDJI, which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. The Fund is subject to certain risks, including the principal risks noted below, any of which may adversely affect the Fund's net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities and other assets in the Underlying Index or in the Fund's portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes.

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units (as defined in the Purchase and Sale of Fund Shares section of the Prospectus), Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for exchange-traded funds (“ETFs”), such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes.

S-3

Currency Risk. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the Fund's NAV may change quickly and without warning.

Custody Risk. Less developed securities markets are more likely to experience problems with the clearing and settling of trades, as well as the holding of securities by local banks, agents and depositories.

Cyber Security Risk. Failures or breaches of the electronic systems of the Fund, the Fund's adviser, distributor, and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions and negatively impact the Fund’s business operations, potentially resulting in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cyber security plans and systems of the Fund’s service providers, the Index Provider, market makers, Authorized Participants or issuers of securities in which the Fund invests.

generally subject their holders to more risks than holders of preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Financials Sector Risk. Performance of companies in the financials sector may be adversely impacted by many factors, including, among others, changes in government regulations, economic conditions, and interest rates, credit rating downgrades, and decreased liquidity in credit markets. The extent to which the Fund may invest in a company that engages in securities-related activities or banking is limited by applicable law. The impact of changes in capital requirements and recent or future regulation of any individual financial company, or of the financials sector as a whole, cannot be predicted. In recent years, cyber-attacks and technology malfunctions and failures have become increasingly frequent in this sector and have caused significant losses to companies in this sector, which may negatively impact the Fund.

Geographic Risk. A natural disaster could occur in a geographic region in which the Fund invests, which could adversely affect the economy or the business operations of companies in the specific geographic region, causing an adverse impact on the Fund's investments in the affected region.

S-4

Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders.

Information Technology Sector Risk. Information technology companies face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by the loss or impairment of those rights.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Lack of Natural Resources Risk. Certain economies to which the Fund may be exposed have few natural resources. Any fluctuation or shortage in the commodity markets could have a negative impact on those economies.

Large-Capitalization Companies Risk. Large-capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large-capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large-capitalization companies has trailed the overall performance of the broader securities markets.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of such an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund's performance may depend on the performance of a small number of issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are

S-5

subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting issuers of non-U.S. securities or non-U.S. markets. In addition, non-U.S. securities markets may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times. The Fund is specifically exposed to Asian Economic Risk and Asian Structural Risk.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and BFA seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have privatized, or have begun the process of privatizing, certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk. The Fund invests in countries or regions

whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund's investments.

Risk of Investing in Asia. Investments in securities of issuers in certain Asian countries involve risks that are specific to Asia, including certain legal, regulatory, political and economic risks. Certain Asian countries have experienced expropriation and/or nationalization of assets, confiscatory taxation, political instability, armed conflict and social instability as a result of religious, ethnic, socio-economic and/or political unrest. In particular, escalated tensions involving North Korea and any outbreak of hostilities involving North Korea, or even the threat of an outbreak of hostilities, could have a severe adverse effect on Asian economies. Some economies in this region are dependent on a range of commodities, and are strongly affected by international commodity prices and particularly vulnerable to price changes for these products. The market for securities in this region may also be directly influenced by the flow of international capital, and by the economic and market conditions of neighboring countries. Many Asian economies have experienced rapid growth and industrialization, and there is no assurance that this growth rate will be maintained. Some Asian economies are highly dependent on trade and economic conditions in other countries can impact these economies.

S-6

markets. Over the last few decades, the Chinese government has undertaken reform of economic and market practices and has expanded the sphere of private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Internal social unrest or confrontations with other neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher rates of inflation. China has experienced security concerns, such as terrorism and strained international relations. Incidents involving China's or the region's security may cause uncertainty in Chinese markets and may adversely affect the Chinese economy and the Fund's investments. Export growth continues to be a major driver of China's rapid economic growth. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers, or a downturn in any of the economies of China's key trading partners may have an adverse impact on the Chinese economy.

or region’s security may cause uncertainty in its markets and may adversely affect its economy and the Fund’s investments. In addition, developed countries may be adversely impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, debt burdens and the price or availability of certain commodities.

Risk of Investing in Emerging Markets. The Fund's investments in emerging market issuers may be subject to a greater risk of loss than investments in issuers located or operating in more developed markets. Emerging markets may be more likely to experience inflation, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, less reliable securities valuations and greater risk associated with custody of securities than developed markets.

Risk of Investing in South Korea. Investments in South Korean issuers may subject the Fund to legal, regulatory, political, currency, security, and economic risks that are specific to South Korea. In addition, economic and political developments of South Korea’s neighbors, including escalated tensions involving North Korea and any outbreak of hostilities involving North Korea, or even the threat of an outbreak of hostilities, may have a severe adverse effect on the South Korean economy.

S-7

These events could also trigger adverse tax consequences for the Fund.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Tracking Error Risk. The Fund may be subject to tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences (including, as applicable, differences between a security’s price at the local market close and the Fund's valuation of a security at the time of calculation of the Fund's NAV), differences in transaction costs, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or interest, tax gains or losses, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. INDEX ETFs THAT TRACK INDICES WITH

SIGNIFICANT WEIGHT IN EMERGING MARKETS ISSUERS MAY EXPERIENCE HIGHER TRACKING ERROR THAN OTHER INDEX ETFs THAT DO NOT TRACK SUCH INDICES.

Average Annual Total Returns

(for the periods ended December 31, 2017)

	One Year	Five Years	Ten Years
(Inception Date: 11/13/2007)
Return Before Taxes	43.51%	9.27%	5.47%
Return After Taxes on Distributions²	42.94%	8.68%	5.00%
Return After Taxes on Distributions and Sale of Fund Shares²	24.97%	7.17%	4.27%

After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sales of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sales of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rachel Aguirre, Diane Hsiung, Jennifer Hsui, Alan Mason, Greg Savage and Amy Whitelaw (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Ms. Aguirre, Ms. Hsiung, Ms. Hsui, Mr. Mason, Mr. Savage and Ms. Whitelaw have been Portfolio Managers of the Fund since 2018, 2008, 2012, 2016, 2008 and 2018, respectively.

Purchase and Sale of Fund Shares

The Fund is an ETF. Individual shares of the Fund are listed on a national securities exchange. Most investors will buy and sell shares of the Fund through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than at NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to Authorized Participants who have entered into agreements with the Fund's distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA, in which case, your distributions generally will be taxed when withdrawn.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on The Nasdaq Stock Market (“NASDAQ”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents an ownership interest in an underlying portfolio of securities and other instruments intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by Authorized Participants and only in Creation Unit increments. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that may not be representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a financial calculation, based on a grouping of financial instruments, and is not an investment product, while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary for a number of reasons, including transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from the Fund's use of representative sampling or from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index. From time to time, the Index Provider may make changes to the methodology or other adjustments to the Underlying Index. Unless otherwise determined by BFA, any such change or adjustment will be reflected in the calculation of the Underlying Index performance on a going-forward basis after the effective date of such change or adjustment. Therefore, the Underlying Index performance shown for periods prior to the effective date of any such change or adjustment will generally not be recalculated or restated to reflect such change or adjustment.

“Tracking error” is the divergence of the performance (return) of the Fund's portfolio from that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in

substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

Under continuous listing standards adopted by the Fund's listing exchange, which went into effect on January 1, 2018, the Fund is required to confirm on an ongoing basis that the components of the Underlying Index satisfy the applicable listing requirements. In the event that the Underlying Index does not comply with the applicable listing requirements, the Fund is required to rectify such non-compliance by requesting that the Index Provider modify the Underlying Index, adopting a new underlying index, or obtaining relief from the SEC. Failure to rectify such non-compliance may result in the Fund being delisted by the listing exchange.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asian Economic Risk. Many Asian economies have experienced rapid growth and industrialization in recent years, but there is no assurance that this growth rate will be maintained. Other Asian economies, however, have experienced high inflation, high unemployment, currency devaluations and restrictions, and over-extension of credit. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia. Any adverse event in the Asian markets may have a significant adverse effect on some or all of the economies of the countries in which the Fund invests. Many Asian countries are subject to political risk, including political instability, corruption and regional conflict with neighboring countries. North Korea and South Korea each have substantial military capabilities, and historical tensions between the two countries present the risk of war. Escalated tensions involving the two countries and any outbreak of hostilities between the two countries, or even the threat of an outbreak of hostilities, could have a severe adverse effect on the entire Asian region. In addition, many Asian countries are subject to social and labor risks associated with demands for improved political, economic and social conditions. These risks, among others, may adversely affect the value of the Fund’s investments.

Asian Structural Risk. Certain Asian countries are subject to a considerable degree of political and social instability, which could adversely affect the Fund's investments:

■

Government Control and Regulations. Governments of many Asian countries have implemented significant economic reforms in order to liberalize trade policies, promote foreign investment in their economies, reduce government control of the economy and develop market mechanisms. There can be no assurance these

	reforms will continue or that they will be effective. Despite recent reform and privatizations, significant regulation of investment and industry is still pervasive in many Asian countries and may restrict foreign ownership of domestic corporations and repatriation of assets, which may adversely affect Fund investments.
■	Political and Social Risk. Governments in some Asian countries are authoritarian in nature, have been installed or removed as a result of military coups or have periodically used force to suppress civil dissent. Disparities of wealth, the pace and success of democratization, and ethnic, religious and racial disaffection may exacerbate social turmoil, violence and labor unrest in some countries. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.
■	Expropriation Risk. Investing in certain Asian countries involves risk of loss due to expropriation, nationalization, or confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested.

Asset Class Risk. The securities and other assets in the Underlying Index or in the Fund’s portfolio may underperform in comparison to other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities, currencies and indexes may experience cycles of outperformance and underperformance in comparison to the general financial markets depending upon a number of factors including, among other things, inflation, interest rates, productivity, global demand for local products or resources, and regulation and governmental controls. This may cause the Fund to underperform other investment vehicles that invest in different asset classes.

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and may be more susceptible to adverse economic, market,

political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

Currency Risk. Because the Fund's NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency, even if such currency value of the Fund's holdings in that market increases. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the Fund’s NAV may change quickly and without warning.

Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades, as well as the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that may not be subject to independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities markets are, the greater the likelihood of custody problems.

Cyber Security Risk. With the increased use of technologies such as the internet to conduct business, the Fund, Authorized Participants, service providers and the relevant listing exchange are susceptible to operational, information security and related “cyber” risks both directly and through their service providers. Similar types of cyber security risks are also present for issuers of securities in which the Fund invests, which could result in material adverse consequences for such issuers and may cause the Fund’s investment in such portfolio companies to lose value. Unlike many other types of risks faced by the Fund, these risks typically are not covered by insurance. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber incidents include, but are not limited to, gaining unauthorized access to digital systems (e.g., through “hacking” or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cyber attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make network services unavailable to intended users). Cyber security failures by or breaches of the systems of the Fund’s adviser, distributor and other service providers (including, but not limited to, index providers, fund accountants, custodians, transfer agents and administrators), market makers, Authorized Participants or the issuers of securities in which the Fund invests, have the ability to cause disruptions and impact business operations, potentially resulting in: financial losses, interference with the Fund’s ability to calculate its NAV, disclosure of confidential trading information, impediments to trading, submission of erroneous trades or erroneous creation or redemption orders, the inability of the Fund or its service providers to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. In addition, cyber attacks may render records of Fund assets and transactions, shareholder ownership of Fund shares, and other data integral to the functioning of the Fund inaccessible or

inaccurate or incomplete. Substantial costs may be incurred by the Fund in order to resolve or prevent cyber incidents in the future. While the Fund has established business continuity plans in the event of, and risk management systems to prevent, such cyber attacks, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified and that prevention and remediation efforts will not be successful. Furthermore, the Fund cannot control the cyber security plans and systems put in place by service providers to the Fund, issuers in which the Fund invests, the Index Provider, market makers or Authorized Participants. The Fund and its shareholders could be negatively impacted as a result.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes. The Underlying Index is comprised of common stocks, which generally subject their holders to more risks than holders of preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Financials Sector Risk. Companies in the financials sector of an economy are subject to extensive governmental regulation and intervention, which may adversely affect the scope of their activities, the prices they can charge, the amount of capital they must maintain and, potentially, their size. The extent to which the Fund may invest in a company that engages in securities-related activities or banking is limited by applicable law. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financials sector, including effects not intended by such regulation. Recently enacted legislation in the U.S. has relaxed capital requirements and other regulatory burdens on certain U.S. banks. While the effect of the legislation may benefit certain companies in the financials sector, increased risk taking by affected banks may also result in greater overall risk in the financials sector. The impact of changes in capital requirements, or recent or future regulation in various countries, on any individual financial company or on the financials sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financials sector more severely than those of investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financials sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Insurance companies, in particular, may be subject to severe price competition and/or rate regulation, which may have an adverse impact on their profitability. The financials sector is particularly sensitive to fluctuations in interest rates. The financials sector is also a target for cyber attacks, and may experience technology malfunctions and disruptions. In recent years, cyber attacks and technology malfunctions and failures have become increasingly frequent in this sector and have reportedly caused losses to companies in this sector, which may negatively impact the Fund.

Geographic Risk. Some of the companies in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, tornadoes, volcanic eruptions, droughts, floods, hurricanes or tsunamis, and are economically sensitive to environmental events. Any such event may adversely impact the economies of these geographic areas or business operations of companies in these geographic areas, causing an adverse impact on the value of the Fund.

Index-Related Risk. The Fund seeks to achieve a return that corresponds generally to the price and yield performance, before fees and expenses, of the Underlying Index as published by the Index Provider. There is no assurance that the Index Provider or any agents that may act on its behalf will compile the Underlying Index accurately, or that the Underlying Index will be determined, composed or calculated accurately. While the Index Provider provides descriptions of what the Underlying Index is designed to achieve, neither the Index Provider nor its agents provide any warranty or accept any liability in relation to the quality, accuracy or completeness of the Underlying Index or its related data, and they do not guarantee that the Underlying Index will be in line with the Index Provider’s methodology. BFA’s mandate as described in this Prospectus is to manage the Fund consistently with the Underlying Index provided by the Index Provider to BFA. BFA does not provide any warranty or guarantee against the Index Provider’s or any agent’s errors. Errors in respect of the quality, accuracy and completeness of the data used to compile the Underlying Index may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, particularly where the indices are less commonly used as benchmarks by funds or managers. Therefore, gains, losses or costs associated with errors of the Index Provider or its agents will generally be borne by the Fund and its shareholders. For example, during a period where the Underlying Index contains incorrect constituents, the Fund would have market exposure to such constituents and would be underexposed to the Underlying Index’s other constituents. Such errors may negatively or positively impact the Fund and its shareholders.

Apart from scheduled rebalances, the Index Provider or its agents may carry out additional ad hoc rebalances to the Underlying Index in order, for example, to correct an error in the selection of index constituents. When the Underlying Index is rebalanced and the Fund in turn rebalances its portfolio to attempt to increase the correlation between the Fund’s portfolio and the Underlying Index, any transaction costs and market exposure arising from such portfolio rebalancing will be borne directly by the Fund and its shareholders. Unscheduled rebalances to the Underlying Index may expose the Fund to additional tracking error risk, which is the risk that the Fund's returns may not track those of the Underlying Index. Therefore, errors and additional ad hoc rebalances carried out by the Index Provider or its agents to the Underlying Index may increase the costs to and the tracking error risk of the Fund.

unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures, credit deterioration of the issuer or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline. An issuer may also be subject to risks associated with the countries, states and regions in which the issuer resides, invests, sells products, or otherwise conducts operations.

Lack of Natural Resources Risk. Some markets in which the Fund invests have limited resources and are heavily dependent on imports for even basic commodities. For example, Singapore is a small island state with few raw material resources and limited land area. Given its size and position, Singapore is sensitive to the socio-political and economic developments of its neighbors, Indonesia and Malaysia, relying on both as markets for Singapore’s service industry and on Malaysia for its raw water supply. In general, any fluctuations or shortages in the commodity markets would have a material impact on the economies in which the Fund invests.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. The value of a security or other asset may decline due to changes in general market conditions, economic trends or events that are not specifically related to the issuer of the security or other asset, or factors that affect a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class. During a general market downturn, multiple asset classes may be negatively affected. Changes in market conditions and interest rates generally do not have the same impact on all types of securities and instruments.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained by market makers or Authorized Participants.

Risk of Secondary Listings. The Fund's shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund's primary listing is maintained, and may otherwise be made available to non-U.S. investors through funds or structured investment vehicles similar to depositary receipts. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund's shares may be less actively traded in certain markets than in others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or for other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market.

Shares of the Fund, similar to shares of other issuers listed on a stock exchange, may be sold short and are therefore subject to the risk of increased volatility and price decreases associated with being sold short.

their NAVs). While the creation/redemption feature is designed to make it more likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund's NAV due to timing reasons, supply and demand imbalances and other factors. In addition, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants, or other market participants, and during periods of significant market volatility, may result in trading prices for shares of the Fund that differ significantly from its NAV. Authorized Participants may be less willing to create or redeem Fund shares if there is a lack of an active market for such shares or its underlying investments, which may contribute to the Fund’s shares trading at a premium or discount to NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission and other charges. In addition, you may incur the cost of the “spread”; that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). The spread, which varies over time for shares of the Fund based on trading volume and market liquidity, is generally narrower if the Fund has more trading volume and market liquidity and wider if the Fund has less trading volume and market liquidity. In addition, increased market volatility may cause wider spreads. There may also be regulatory and other charges that are incurred as a result of trading activity. Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments through a brokerage account.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks of investing in the markets where such issuers are located, including heightened risks of inflation, nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

■	Lower levels of liquidity and market efficiency;

■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;
■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements; and

■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the U.S.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index, regardless of their investment merits. BFA generally does not attempt to invest the Fund's assets in defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have privatized, or have begun the process of privatizing, certain entities and industries. Newly privatized companies may face strong competition from government-sponsored competitors that have not been privatized. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that similar losses will not recur.

Reliance on Trading Partners Risk. Economies in emerging market countries generally are heavily dependent upon commodity prices and international trade and, accordingly, have been and may continue to be affected adversely by the economies of their trading partners, trade barriers, exchange controls, managed adjustments in relative currency values, and may suffer from extreme and volatile debt burdens or inflation rates. These countries may be subject to other protectionist measures imposed or negotiated by the countries with which they trade.

Risk of Investing in China. Investments in Chinese securities, including certain Hong Kong-listed securities, subject the Fund to risks specific to China. The Chinese economy is subject to a considerable degree of economic, political and social instability:

Political and Social Risk. The Chinese government is authoritarian and has periodically used force to suppress civil dissent. Disparities of wealth and the pace of economic liberalization may lead to social turmoil, violence and labor unrest. In addition, China continues to experience disagreements related to integration with Hong Kong and religious and nationalist disputes in Tibet and Xinjiang. There is also a greater risk in China than in many other countries of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher rates of inflation as a result of internal social unrest or conflicts with other countries. Unanticipated political or social developments may result in sudden and significant investment losses. China's growing income inequality, rapidly aging population and significant environmental issues also are factors that may affect the Chinese economy.

Government Control and Regulations. The Chinese government has implemented significant economic reforms in order to liberalize trade policy, promote foreign investment in the economy, reduce government control of the economy and develop market mechanisms. There can be no assurance these reforms will continue or that they will be effective. Despite recent reform and privatizations, government control over certain sectors or enterprises and significant regulation of investment and industry is still pervasive, including restrictions on investment in companies or industries deemed to be sensitive to particular national interests, and the Chinese government may restrict foreign ownership of Chinese corporations and/or the repatriation of assets by foreign investors. Limitations or restrictions on foreign ownership of securities may have adverse effects on the liquidity and performance of the Fund, and could lead to higher tracking error. Government market interventions may have a negative impact on market sentiment, which may in turn affect the performance of the Chinese economy and the Fund’s investments. Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies that may be connected to governmental influence, lack of publicly-available information and/or political and social instability.

Economic Risk. The Chinese economy has grown rapidly in the recent past and there is no assurance that this growth rate will be maintained. In fact, the Chinese economy may experience a significant slowdown as a result of, among other things, a deterioration in global demand for Chinese exports, as well as contraction in spending on domestic goods by Chinese consumers. In addition, China may experience substantial rates of inflation or economic recessions, which would have a negative effect on its economy and securities market. Delays in enterprise restructuring, slow development of well-functioning financial markets and widespread corruption have also hindered performance of the Chinese economy. China continues to receive substantial pressure from trading partners to liberalize official currency exchange rates. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers, including as a result of heightened trade tensions between China

and the U.S., or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy.

Expropriation Risk. The Chinese government maintains a major role in economic policymaking and investing in China involves risk of loss due to expropriation, nationalization, or confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested.

Security Risk. China has strained international relations with Taiwan, India, Russia and other neighbors due to territorial disputes, historical animosities, defense concerns and other security concerns. Relations between China’s Han ethnic majority and other ethnic groups in China, including Tibetans and Uighurs, are also strained and have been marked by protests and violence. These situations may cause uncertainty in the Chinese market and may adversely affect the Chinese economy. In addition, conflict on the Korean Peninsula could adversely affect the Chinese economy.

Chinese Equity Markets. The Fund may invest in H-shares (securities of companies incorporated in the People's Republic of China (“PRC”) that are denominated in Hong Kong dollars and listed on the Stock Exchange of Hong Kong). The Fund may also invest in certain Hong Kong listed securities known as Red-Chips (securities issued by companies incorporated in certain foreign jurisdictions, which are controlled, directly or indirectly, by entities owned by the national government or local governments in the PRC and derive substantial revenues or allocate substantial assets in the PRC) and P-Chips (securities issued by companies incorporated in certain foreign jurisdictions, which are controlled, directly or indirectly, by individuals in the PRC and derive substantial revenues or allocate substantial assets in the PRC). The issuance of H-shares by Chinese companies and the ability to obtain a “back-door listing” through Red-Chips or P-Chips is still regarded by the Chinese authorities as an experiment in economic reform. “Back-door listing” is a means by which a mainland Chinese company issues Red-Chips or P-Chips to obtain quick access to international listing and international capital. All of these share mechanisms are relatively untested and subject to political and economic policy in China.

Hong Kong Political Risk. Hong Kong reverted to Chinese sovereignty on July 1, 1997 as a Special Administrative Region (SAR) of the PRC under the principle of “one country, two systems.” Although China is obligated to maintain the current capitalist economic and social system of Hong Kong through June 30, 2047, the continuation of economic and social freedoms enjoyed in Hong Kong is dependent on the government of China. Any attempt by China to tighten its control over Hong Kong's political, economic, legal or social policies may result in an adverse effect on Hong Kong's markets. In addition, the Hong Kong dollar trades at a fixed exchange rate in relation to (or, is “pegged” to) the U.S. dollar, which has contributed to the growth and stability of the Hong Kong economy. However, it is uncertain how long the currency peg will continue or what effect the establishment of an alternative exchange rate system would have on the Hong Kong economy. Because the Fund's NAV is denominated in U.S. dollars, the establishment of an alternative exchange rate system could result in a decline in the Fund's NAV.

Risk of Investing in Developed Countries. Investment in developed country issuers may subject the Fund to regulatory, political, currency, security, economic and other

risks associated with developed countries. Developed countries generally tend to rely on services sectors (e.g., the financial services sector) as the primary means of economic growth. A prolonged slowdown in one or more services sectors is likely to have a negative impact on economies of certain developed countries, although economies of individual developed countries can be impacted by slowdowns in other sectors. In the past, certain developed countries have been targets of terrorism, and some geographic areas in which the Fund invests have experienced strained international relations due to territorial disputes, historical animosities, defense concerns and other security concerns. These situations may cause uncertainty in the financial markets in these countries or geographic areas and may adversely affect the performance of the issuers to which the Fund has exposure. Heavy regulation of certain markets, including labor and product markets, may have an adverse effect on certain issuers. Such regulations may negatively affect economic growth or cause prolonged periods of recession. Many developed countries are heavily indebted and face rising healthcare and retirement expenses. In addition, price fluctuations of certain commodities and regulations impacting the import of commodities may negatively affect developed country economies.

Risk of Investing in Emerging Markets. Investments in emerging market issuers are subject to a greater risk of loss than investments in issuers located or operating in more developed markets. This is due to, among other things, the potential for greater market volatility, lower trading volume, higher levels of inflation, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments in emerging market countries than are typically found in more developed markets. Additionally, the risk of nationalization of private assets is greater in emerging market countries than developed countries. Moreover, emerging markets often have less uniformity in accounting and reporting requirements, less reliable securities valuations and greater risks associated with custody of securities than developed markets. In addition, emerging markets often have greater risk of capital controls through such measures as taxes or interest rate control than developed markets. Certain emerging market countries may also lack the infrastructure necessary to attract large amounts of foreign trade and investment.

Risk of Investing in South Korea. Investments in South Korean issuers involve risks that are specific to South Korea, including legal, regulatory, political, currency, security and economic risks. Substantial political tensions exist between North Korea and South Korea. Escalated tensions involving the two nations and the outbreak of hostilities between the two nations, or even the threat of an outbreak of hostilities, could have a severe adverse effect on the South Korean economy. In addition, South Korea's economic growth potential has recently been on a decline because of a rapidly aging population and structural problems, among other factors. The South Korean economy is heavily reliant on trading exports and disruptions or decreases in trade activity could lead to further declines.

loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund. BlackRock Institutional Trust Company, N.A., the Fund's securities lending agent, will take into account the tax impact to shareholders of substitute payments for dividends when managing the Fund's securities lending program.

Structural Risk. Certain political, economic, legal and currency risks could contribute to a high degree of price volatility in the equity markets of some of the countries in which the Fund may invest and could adversely affect investments in the Fund.

Political and Social Risk. Disparities of wealth, the pace and success of democratization and ethnic, religious and racial disaffection, among other factors, may exacerbate social unrest, violence and labor unrest in some of the countries in which the Fund may invest. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.

Economic Risk. Some countries in which the Fund may invest may experience economic instability, including instability resulting from substantial rates of inflation or significant devaluations of their currency, or economic recessions, which would have a negative effect on the economies and securities markets of their economies. Some of these countries may also impose restrictions on the exchange or export of currency or adverse currency exchange rates and may be characterized by a lack of available currency hedging instruments.

Expropriation Risk. Investments in certain countries in which the Fund may invest may be subject to loss due to expropriation or nationalization of assets and property or the imposition of restrictions on foreign investments and repatriation of capital.

Large Government Debt Risk. Chronic structural public sector deficits in some countries in which the Fund may invest may adversely impact securities held by the Fund.

in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund's NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using prevailing market rates on the date of valuation as quoted by one or more data service providers. This conversion may result in a difference between the prices used to calculate the Fund's NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund's performance and the performance of the Underlying Index. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Close-out Risk for Qualified Financial Contracts. Recently adopted regulations of the Prudential Regulators, which are scheduled to take effect with respect to the Fund in 2019, will require counterparties that are part of U.S. or foreign global systemically important banking organizations to include contractual restrictions on close-out and cross-default in agreements relating to qualified financial contracts. Qualified financial contracts include agreements relating to swaps, currency forwards and other derivatives as well as repurchase agreements and securities lending agreements. The restrictions prevent the Fund from closing out a qualified financial contract during a specified time period if the counterparty is subject to resolution proceedings and prohibit the Fund from exercising default rights due to a receivership or similar proceeding of an affiliate of the counterparty. Implementation of these requirements may increase credit and other risks to the Fund.

Threshold/Underinvestment Risk. If certain aggregate ownership thresholds are reached either through the actions of BFA and its affiliates or the Fund, or as a result of third-party transactions, the ability of BFA and its affiliates on behalf of clients (including the Fund) to purchase or dispose of investments, or exercise rights or undertake business transactions, may be restricted by regulation or otherwise impaired. The capacity of the Fund to make investments in certain securities may be affected by the relevant threshold limits, and such limitations may have adverse effects on the liquidity and performance of the Fund’s portfolio holdings compared to the performance of the Underlying Index. This may increase the risk of the Fund being underinvested to the Underlying Index and increase the risk of tracking error.

Portfolio Holdings Information

A description of the Trust's policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund's Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund's top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Fund. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund's investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except the management fees, interest expenses, taxes, expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, distribution fees or expenses, litigation expenses and any extraordinary expenses (as determined by a majority of the Trustees who are not “interested persons” of the Trust).

For its investment advisory services to the Fund, BFA is paid a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.50%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

A discussion regarding the basis for the approval by the Trust's Board of Trustees (the “Board”) of the Investment Advisory Agreement with BFA is available in the Fund's semi-annual report for the period ended September 30.

Portfolio Managers. Rachel Aguirre, Diane Hsiung, Jennifer Hsui, Alan Mason, Greg Savage and Amy Whitelaw are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing

investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rachel Aguirre has been with BlackRock since 2006, including her years with Barclays Global Investors (“BGI’), which merged with BlackRock in 2009. Ms. Aguirre has been employed by BFA or its affiliates as a portfolio manager since 2006 and has been a Portfolio Manager of the Fund since 2018.

Diane Hsiung has been employed by BFA as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for Barclays Global Fund Advisors (“BGFA”). Ms. Hsiung has been a Portfolio Manager of the Fund since 2008.

Jennifer Hsui has been employed by BFA as a senior portfolio manager since 2007. Prior to that, Ms. Hsui was a portfolio manager from 2006 to 2007 for BGFA. Ms. Hsui has been a Portfolio Manager of the Fund since 2012.

Alan Mason has been employed by BFA as a portfolio manager since 1991. Mr. Mason has been a Portfolio Manager of the Fund since 2016.

Greg Savage has been employed by BFA as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA. Mr. Savage has been a Portfolio Manager of the Fund since 2008.

Amy Whitelaw has been with BlackRock since 1999, including her years with BGI, which merged with BlackRock in 2009. Ms. Whitelaw has been employed by BFA or its affiliates as a portfolio manager since 2009 and has been a Portfolio Manager of the Fund since 2018.

The Fund's SAI provides additional information about the Portfolio Managers' compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers' ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

commodities, derivatives and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA or an Affiliate performs or seeks to perform investment banking or other services. Specifically, the Fund may invest in securities of, or engage in other transactions with, companies with which an Affiliate has developed or is trying to develop investment banking relationships or in which an Affiliate has significant debt or equity investments or other interests. The Fund also may invest in securities of, or engage in other transactions with, companies for which an Affiliate provides or may in the future provide research coverage. An Affiliate may have business relationships with, and purchase, distribute or sell services or products from or to, distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates in connection with the Fund's portfolio investment transactions.

BFA or an Affiliate may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including securities issued by other open-end and closed-end investment companies (which may include investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”)). The trading activities of BFA and these Affiliates are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA or an Affiliate having positions in certain securities that are senior or junior to, or having interests different from or adverse to, the securities that are owned by the Fund.

No Affiliate is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate may compete with the Fund for appropriate investment opportunities. The results of the Fund's investment activities, therefore, may differ from those of an Affiliate and of other accounts managed by an Affiliate, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

In addition, the Fund may, from time to time, enter into transactions in which BFA’s or an Affiliate’s other clients have an adverse interest. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate-advised clients or by BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

The Fund's activities may be limited because of regulatory restrictions applicable to one or more Affiliates and/or their internal policies designed to comply with such restrictions.

Affiliate will also receive compensation for managing the reinvestment of cash collateral. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA or the Affiliates may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund's SAI for further information.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section below) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange or otherwise in the secondary market. The Fund's shares trade under the ticker symbol “AIA.”

Buying or selling Fund shares on an exchange or other secondary market involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you may incur a brokerage commission and other charges. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread,” that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on the Fund’s trading volume and market liquidity, and is generally lower if the Fund has high trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity (which is often the case for funds that are newly launched or small in size). The Fund's spread may also be impacted by the liquidity of the underlying securities held by the Fund, particularly for newly launched or smaller funds or in instances of significant volatility of the underlying securities.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of

monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund's shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays (or the days on which they are observed): New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NASDAQ.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of, and holds legal title to, all outstanding shares of the Fund.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as the supply of and demand for ETF shares and shares of underlying securities held by the Fund, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout each trading day by the national securities exchange on which the Fund's shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities or other assets and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities or other assets held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund's NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and price quotations obtained from broker-dealers and other market intermediaries that may trade in the portfolio securities or other assets held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do

not trade in the U.S. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Equity investments and other instruments for which market quotations are readily available, as well as investments in an underlying fund, if any, are valued at market value, which is generally determined using the last reported official closing price or, if a reported closing price is not available, the last traded price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in non-U.S. securities. Foreign currency exchange rates with respect to the portfolio securities denominated in non-U.S. currencies are generally determined as of 4:00 p.m., London time. Non-U.S. securities held by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants (as defined in the Creations and Redemptions section of this Prospectus) will not be able to purchase or redeem Fund shares.

Generally, trading in non-U.S. securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity or other reasons, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, when there is a significant event subsequent to the most recent market quotation, or if the trading market on which a security is listed is suspended or closed and no appropriate alternative trading market is available. A “significant event” is deemed to occur if BFA determines, in its reasonable business judgment prior to or at the time of pricing the Fund’s assets or liabilities, that the event

is likely to cause a material change to the closing market price of one or more assets or liabilities held by the Fund. Non-U.S. securities whose values are affected by volatility that occurs in the local markets or in related or highly correlated assets (e.g., American Depositary Receipts, Global Depositary Receipts or substantially identical ETFs) on a trading day after the close of non-U.S. securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the prices at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using prevailing market rates on the date of valuation as quoted by one or more data service providers. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid at least once a year by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general

information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains, if any, in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates. Long-term capital gains and qualified dividend income are generally eligible for taxation at a maximum rate of 15% or 20% for non-corporate shareholders, depending on whether their income exceeds certain threshold amounts. In addition, a 3.8% U.S. federal Medicare contribution tax is imposed on “net investment income,” including, but not limited to, interest, dividends, and net gain, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly) and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the U.S., which includes an exchange of information program, or if the stock with respect to which the dividend was paid is readily tradable on an established U.S. securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. Distributions in excess of the Fund’s minimum distribution requirements, but not in excess of the Fund’s earnings and profits, will be taxable to shareholders and will not constitute nontaxable returns of capital. The Fund’s capital loss carryforwards, if any, carried from taxable years beginning before 2011 do not reduce current earnings and profits, even if such carryforwards offset current year realized gains. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder's cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

Dividends, interest and capital gains earned by the Fund with respect to securities issued by non-U.S. issuers may give rise to withholding, capital gains and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the U.S. may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities (generally, for this purpose, depositary receipts, no matter where traded, of non-U.S. companies are treated as “non-U.S.”), generally the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, limiting the availability of such credits for U.S. persons.

If you are neither a resident nor a citizen of the U.S. or if you are a non-U.S. entity (other than a pass-through entity to the extent owned by U.S. persons), the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

foreign financial institutions will need to (i) enter into agreements with the IRS that state that they will provide the IRS information, including the names, addresses and taxpayer identification numbers of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information concerning their account holders, or (ii) in the event that an applicable intergovernmental agreement and implementing legislation are adopted, provide local revenue authorities with similar account holder information. Other foreign entities may need to report the name, address, and taxpayer identification number of each substantial U.S. owner or provide certifications of no substantial U.S. ownership unless certain exceptions apply.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income. In addition, you may lose the ability to use foreign tax credits passed through by the Fund if your Fund shares are loaned out pursuant to a securities lending agreement.

If you are a resident or a citizen of the U.S., by law, backup withholding at a 24% rate will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Any such capital gains, including from sales of Fund shares or from capital gain dividends, are included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax advisor about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Chinese Tax Disclosure. The Fund’s investments in securities, issued by PRC companies may cause the Fund to become subject to withholding and other taxes imposed by the PRC. If the Fund were considered to be a tax resident of the PRC, it would be subject to PRC corporate income tax at the rate of 25% on its worldwide taxable income. If the Fund were considered to be a non-resident enterprise with a “permanent establishment” in the PRC, it would be subject to PRC corporate income tax of 25% on the profits attributable to the permanent establishment. BFA intends to operate the Fund in a manner that will prevent it from being treated as a tax resident of the PRC and from having a permanent establishment in the PRC. It is possible, however, that the PRC could disagree with that conclusion or that changes in PRC tax

law could affect the PRC corporate income tax status of the Fund. The PRC generally imposes withholding income tax at a rate of 10% on dividends, premiums, interest and capital gains originating in the PRC and paid to a company that is not a resident of the PRC for tax purposes and that has no permanent establishment in China. The withholding is in general made by the relevant PRC tax resident company making such payments. In the event the relevant PRC tax resident company fails to withhold the relevant PRC withholding income tax or otherwise fails to pay the relevant withholding income tax to the PRC tax authorities, the competent PRC tax authorities may, at their sole discretion, impose tax obligations on the Fund. Foreign investors will be temporarily exempt from withholding income tax on capital gains derived from the trading of certain shares starting on November 17, 2014. The exemptions are temporary and there is no indication how long the exemptions will continue. While the application and enforcement of this law to the Fund remains subject to clarification, to the extent that such taxes are imposed on any capital gains of the Fund, the Fund's NAV or returns may be adversely impacted. Stamp duty under the PRC laws generally applies to the execution and receipt of taxable documents, which include contracts for the sale of shares traded on PRC stock exchanges. In the case of such contracts, the stamp duty is currently imposed on the seller but not on the purchaser, at the rate of 0.1%.

The above information is only a general summary of the potential PRC tax consequences that may be imposed on the Fund and its investors either directly or indirectly and should not be taken as a definitive, authoritative or comprehensive statement of the relevant matter. Investors should seek their own tax advice on their tax position with regard to their investment in the Fund.

The PRC government has implemented a number of tax reform policies in recent years. The current tax laws and regulations may be revised or amended in the future. Any revision or amendment in tax laws and regulations may affect the after-taxation profit of PRC companies and foreign investors in such companies, such as the Fund.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or authorized participant (an “Authorized Participant”) has entered into an agreement with the Fund's distributor, BlackRock Investments, LLC (the “Distributor”), an affiliate of BFA.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund generally offers Creation Units partially for cash, but may, in certain circumstances, offer Creation Units solely for cash or solely in-kind.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities (including any portion of such securities for which cash may be substituted) held by the Fund and a specified amount of cash. Except when aggregated in Creation Units, shares are not redeemable by the Fund.

The prices at which creations and redemptions occur are based on the next calculation of NAV after a creation or redemption order is received in an acceptable form under the authorized participant agreement.

Only an Authorized Participant may create or redeem Creation Units with the Fund. Authorized Participants may create or redeem Creation Units for their own accounts or for customers, including, without limitation, affiliates of the Fund.

In the event of a system failure or other interruption, including disruptions at market makers or Authorized Participants, orders to purchase or redeem Creation Units either may not be executed according to the Fund's instructions or may not be executed at all, or the Fund may not be able to place or change orders.

To the extent the Fund engages in in-kind transactions, the Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined in Rule 144A under the 1933 Act, will not be able to receive restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant that has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund's SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(a)(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(a)(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

amount shown in the table regardless of the number of Creation Units being purchased or redeemed, but may be reduced by the Fund if transfer and processing expenses associated with the creation or redemption are anticipated to be lower than the stated fee. If a purchase or redemption consists solely or partially of cash, the Authorized Participant may also be required to pay an additional transaction charge (up to the maximum amounts shown in the table below) to cover brokerage and certain other costs related to a creation or redemption transaction. Investors who use the services of a broker or other financial intermediary to acquire or dispose of Fund shares may pay fees for such services.

The following table shows, as of April 30, 2018, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above and in the Fund's SAI):

Approximate Value of a Creation Unit		Creation Unit Size		Standard Creation/ Redemption Transaction Fee		Maximum Additional Charge for Creations*		Maximum Additional Charge for Redemptions*
$3,398,500		50,000		$2,500		7.0%		2.0%

*	As a percentage of the net asset value per Creation Unit, inclusive, in the case of redemptions, of the standard redemption transaction fee.

If a purchase or redemption consists solely or partially of cash and the Fund places a brokerage transaction for portfolio securities with the Authorized Participant or its affiliated broker-dealer, the Authorized Participant (or an affiliated broker-dealer of the Authorized Participant) may be required, in its capacity as broker-dealer with respect to that transaction, to cover certain brokerage, tax, foreign exchange, execution, and price movement costs through a brokerage execution guarantee, as further described in the Fund’s SAI.

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor or its agent distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is 1 University Square Drive, Princeton, NJ 08540.

BFA or its affiliates make payments to broker-dealers, registered investment advisers, banks or other intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, data provision services, or their making shares of the Fund and certain other iShares funds available to their customers generally and in certain investment programs. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the payments or other financial incentives it is eligible to receive. Therefore, such payments or other financial incentives offered or made to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund's SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance for the past five years. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund's financial statements, in the Fund's Annual Report (available upon request).

^b	The amounts reported for a share outstanding may not accord with the change in aggregate gains and losses in securities for the fiscal period due to the timing of capital share transactions in relation to the fluctuating market values of the Fund’s underlying securities.

The total return presented was calculated using the beginning net asset value as of March 28, 2013 (the last day the Fund’s listing exchange was open during the year ended March 31, 2013). For financial reporting purposes, the Fund’s investments were fair valued as of the reporting date of March 31, 2013 which took into account certain foreign exchanges that were open for trading on March 29, 2013. As such, the total return calculated for financial reporting purposes for the year ended March 31, 2014 was 1.35%.

Portfolio turnover rates exclude portfolio securities received or delivered in Creation Units but include portfolio transactions that are executed as a result of the Fund processing capital share transactions in Creation Units partially for cash in U.S. dollars. Excluding such cash transactions, the portfolio turnover rates for the years ended March 31, 2018, March 31, 2017, March 31, 2016, March 31, 2015 and March 31, 2014 were 10%, 9%, 7%, 12% and 9%, respectively.

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest ask on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund for each full calendar quarter of 2017 and the first two calendar quarters of 2018.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

Premium/Discount Range	Number of Days	Percentage of Total Days
Greater than 3.0% and Less than 3.5%	1	0.27%
Greater than 2.5% and Less than 3.0%	2	0.53

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended March 31, 2018.

“Average Annual Total Returns” represents the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represents the total change in value of an investment over the periods indicated.

An index is a financial calculation, based on a grouping of financial instruments, that is not an investment product and that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions and other charges that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Performance as of March 31, 2018

	Average Annual Total Returns			Cumulative Total Returns
	NAV	MARKET	INDEX	NAV	MARKET	INDEX
1 Year	29.73%*	31.94%	30.14%	29.73%*	31.94%	30.14%
5 Years	10.13%	10.42%	10.72%	62.02%	64.12%	66.43%
10 Years	6.81%	6.90%	7.38%	93.31%	94.92%	103.83%

The NAV total return presented in the table for the one-year period differs from the same period return disclosed in the financial highlights. The total return in the financial highlights is calculated in the same manner but differs due to certain adjustments made for financial reporting purposes in accordance with U.S. generally accepted accounting principles.

iSHARES^® CORE S&P 500 ETF

Ticker: IVV

Stock Exchange: NYSE Arca

Investment Objective

The iShares Core S&P 500 ETF (the “Fund”) seeks to track the investment results of an index composed of large-capitalization U.S. equities.

Fees and Expenses

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

S-1

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P 500 (the “Underlying Index”), which measures the performance of the large-capitalization sector of the U.S. equity market, as determined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). As of March 31, 2018, the Underlying Index included approximately 82% of the market capitalization of all publicly-traded U.S. equity securities. The securities in the Underlying Index are weighted based on the float-adjusted market value of their outstanding shares. The Underlying Index consists of securities from a broad range of industries. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the information technology industry or sector. The components of the Underlying Index are likely to change over time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index and in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, as well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

S-2

The Underlying Index is a product of SPDJI which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

Summary of Principal Risks

orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units (as defined in the Purchase and Sale of Fund Shares section of the Prospectus), Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Index-Related Risk. There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders.

overall performance of the broader securities markets.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Risk of Investing in the United States. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on

S-4

the securities to which the Fund has exposure.

Tracking Error Risk. The Fund may be subject to tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur because of

differences between the securities and other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences, differences in transaction costs, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or interest, tax gains or losses, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

Management

Investment Adviser. BlackRock Fund Advisors.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual shares of the Fund are listed on a national securities exchange. Most investors will buy and sell shares of the Fund through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than at NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to Authorized Participants who have entered into agreements with the Fund's distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and

may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Information Technology Sector Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on their profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Market Trading Risk

investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below the Fund’s most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Fund's shares fluctuates continuously throughout trading hours based on both market supply of and demand for Fund shares and the underlying value of the Fund's portfolio holdings or NAV. As a result, the trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV, BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long term (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs). While the creation/redemption feature is designed to make it more likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund's NAV due to timing reasons, supply and demand imbalances and other factors. In addition, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants, or other market participants, and during periods of significant market volatility, may result in trading prices for shares of the Fund that differ significantly from its NAV. Authorized Participants may be less willing to create or redeem Fund shares if there is a lack of an active market for such shares or its underlying investments, which may contribute to the Fund’s shares trading at a premium or discount to NAV.

“bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). The spread, which varies over time for shares of the Fund based on trading volume and market liquidity, is generally narrower if the Fund has more trading volume and market liquidity and wider if the Fund has less trading volume and market liquidity. In addition, increased market volatility may cause wider spreads. There may also be regulatory and other charges that are incurred as a result of trading activity. Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments through a brokerage account.

Risk of Investing in the United States. A decrease in imports or exports, changes in trade regulations and/or an economic recession in the U.S. may have a material adverse effect on the U.S. economy and the securities listed on U.S. exchanges. Proposed and adopted policy and legislative changes in the U.S. are changing many aspects of financial and other regulation and may have a significant effect on the U.S. markets generally, as well as on the value of certain securities. In addition, a continued rise in the U.S. public debt level or U.S. austerity measures may adversely affect U.S. economic growth and the securities to which the Fund has exposure.

The U.S. has developed increasingly strained relations with a number of foreign countries, including traditional allies, such as major European countries, the U.K., Canada and Mexico, and historical adversaries, such as North Korea, Iran, China and Russia. If these relations were to worsen, it could adversely affect U.S. issuers as well as non-U.S. issuers that rely on the U.S. for trade. The U.S. has also experienced increased internal unrest and discord. If this trend were to continue, it may have an adverse impact on the U.S. economy and the issuers in which the Fund invests.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund. BlackRock Institutional Trust Company, N.A., the Fund's securities lending agent, will

take into account the tax impact to shareholders of substitute payments for dividends when managing the Fund's securities lending program.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

Energy Sector Risk. The success of companies in the energy sector may be cyclical and highly dependent on energy prices. The market value of securities issued by companies in the energy sector may decline for many reasons, including, among other things: changes in the levels and volatility of global energy prices, energy supply and demand, and capital expenditures on exploration and production of energy sources; exchange rates, interest rates, economic conditions, and tax treatment; energy conservation efforts, increased competition and technological advances. Companies in this sector may be subject to substantial government regulation and contractual fixed pricing, which may increase the cost of doing business and limit the earnings of these companies. A significant portion of the revenues of these companies may depend on a relatively small number of customers, including governmental entities and utilities. As a result, governmental budget constraints may have a material adverse effect on the stock prices of companies in this sector. Energy companies may also operate in, or engage in, transactions involving countries with less developed regulatory regimes or a history of expropriation, nationalization or other adverse policies. Energy companies also face a significant risk of liability from accidents resulting in injury or loss of life or property, pollution or other environmental problems, equipment malfunctions or mishandling of materials and a risk of loss from terrorism, political strife or natural disasters. Any such event could have serious consequences for the general population of the affected area and could have an adverse impact on the Fund’s portfolio and the performance of the Fund. Energy companies can be significantly affected by the supply of, and demand for, specific products (e.g., oil and natural gas) and services, exploration and production spending, government subsidization, world events and general economic conditions. Energy companies may have relatively high levels of debt and may be more likely than other companies to restructure their businesses if there are downturns in energy markets or in the global economy.

competition and/or rate regulation, which may have an adverse impact on their profitability. The financials sector is particularly sensitive to fluctuations in interest rates. The financials sector is also a target for cyber attacks, and may experience technology malfunctions and disruptions. In recent years, cyber attacks and technology malfunctions and failures have become increasingly frequent in this sector and have reportedly caused losses to companies in this sector, which may negatively impact the Fund.

Healthcare Sector Risk. The profitability of companies in the healthcare sector may be adversely affected by the following factors, among others: extensive government regulations, restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure, an increased emphasis on outpatient services, a limited number of products, industry innovation, changes in technologies and other market developments. A number of issuers in the healthcare sector have recently merged or otherwise experienced consolidation. The effects of this trend toward consolidation are unknown and may be far-reaching. Many healthcare companies are heavily dependent on patent protection. The expiration of a company’s patents may adversely affect that company’s profitability. Many healthcare companies are subject to extensive litigation based on product liability and similar claims. Healthcare companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the healthcare sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly, and such efforts ultimately may be unsuccessful. Companies in the healthcare sector may be thinly capitalized and may be susceptible to product obsolescence. In addition, a number of legislative proposals concerning healthcare have been considered by the U.S. Congress in recent years. It is unclear what proposals will ultimately be enacted, if any, and what effect they may have on companies in the healthcare sector.

undertake business transactions, may be restricted by regulation or otherwise impaired. The capacity of the Fund to make investments in certain securities may be affected by the relevant threshold limits, and such limitations may have adverse effects on the liquidity and performance of the Fund’s portfolio holdings compared to the performance of the Underlying Index. This may increase the risk of the Fund being underinvested to the Underlying Index and increase the risk of tracking error.

BFA and the other Affiliates are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA or one or more of the other Affiliates acts, or may act, as an investor, investment banker, research provider, investment manager, commodity pool operator, commodity trading advisor, financier, underwriter, adviser, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests in securities, currencies, commodities, derivatives and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA or an Affiliate performs or seeks to perform investment banking or other services. Specifically, the Fund may invest in securities of, or engage in other transactions with, companies with which an Affiliate has developed or is trying to develop investment banking relationships or in which an Affiliate has significant debt or equity investments or other interests. The Fund also may invest in securities of, or engage in other transactions with, companies for which an Affiliate provides or may in the future provide research coverage. An Affiliate may have business relationships with, and purchase, distribute or sell services or products from or to, distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates in connection with the Fund's portfolio investment transactions.

one or more Affiliate-advised clients or by BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

The Fund's activities may be limited because of regulatory restrictions applicable to one or more Affiliates and/or their internal policies designed to comply with such restrictions.

Under a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the securities lending agent will retain a share of the securities lending revenues. BFA or an Affiliate will also receive compensation for managing the reinvestment of cash collateral. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

Shareholder Information

underlying securities held by the Fund, particularly for newly launched or smaller funds or in instances of significant volatility of the underlying securities.

(“IOPV”), is disseminated every 15 seconds throughout each trading day by the national securities exchange on which the Fund's shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities or other assets and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities or other assets held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund's NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and price quotations obtained from broker-dealers and other market intermediaries that may trade in the portfolio securities or other assets held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the U.S. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Dividends and Distributions

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, in which case your distributions generally

will be taxable when withdrawn, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

Fund distributions, to the extent attributable to dividends from U.S. corporations, will be eligible for the dividends received deduction for Fund shareholders that are corporations, subject to certain hedging and holding requirements.

Separately, a 30% withholding tax is currently imposed on U.S.-source dividends, interest and other income items and will be imposed on proceeds from the sale, redemption or other disposition of property producing U.S.-source dividends and interest paid after December 31, 2018, to (i) foreign financial institutions, including non-U.S. investment funds, unless they agree to collect and disclose to the U.S. Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to (i) enter into agreements with the IRS that state that they will provide the IRS information, including the names, addresses and taxpayer identification numbers of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information concerning their account holders, or (ii) in the event that an applicable intergovernmental agreement and implementing legislation are adopted, provide local revenue authorities with similar account holder information. Other foreign entities may need to report the name, address, and taxpayer identification number of each substantial U.S. owner or provide certifications of no substantial U.S. ownership unless certain exceptions apply.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

In the event of a system failure or other interruption, including disruptions at market makers or Authorized Participants, orders to purchase or redeem Creation Units either

may not be executed according to the Fund's instructions or may not be executed at all, or the Fund may not be able to place or change orders.

available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, price movement and other costs and expenses related to cash transactions (which may, in certain instances, be based on a good faith estimate of transaction costs). Investors who use the services of a broker or other financial intermediary to acquire or dispose of Fund shares may pay fees for such services.

Approximate Value of a Creation Unit		Creation Unit Size		Standard Creation/ Redemption Transaction Fee		Maximum Additional Charge for Creations*		Maximum Additional Charge for Redemptions*
$13,311,000		50,000		$1,250		3.0%		2.0%

iSHARES^® CORE S&P MID-CAP ETF

Ticker: IJH

Stock Exchange: NYSE Arca

Investment Objective

The iShares Core S&P Mid-Cap ETF (the “Fund”) seeks to track the investment results of an index composed of mid-capitalization U.S. equities.

Fees and Expenses

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

S-1

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P MidCap 400^® (the “Underlying Index”), which measures the performance of the mid-capitalization sector of the U.S. equity market, as determined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). As of March 31, 2018, the Underlying Index included approximately 7% of the market capitalization of all publicly-traded U.S. equity securities. The securities in the Underlying Index are weighted based on the float-adjusted market value of their outstanding shares, have, as of March 31, 2018, a market capitalization between $1.4 billion and $5.9 billion at time of entry, which may fluctuate depending on the overall level of the equity markets, and are selected by SPDJI for liquidity and industry group representation. The Underlying Index consists of securities from a broad range of industries. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the financials, industrials and information technology industries or sectors. The components of the Underlying Index are likely to change over time.

results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption

transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units (as defined in the Purchase and Sale of Fund Shares section of the Prospectus), Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

S-3

Equity Securities Risk. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. The Underlying Index is comprised of common stocks, which generally subject their holders to more risks than holders of preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders.

Industrials Sector Risk. Companies in the industrials sector may be adversely affected by changes in the supply of and demand for products and services, product obsolescence, claims for environmental damage or product liability and changes in general economic conditions, among other factors.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

S-4

Mid-Capitalization Companies Risk. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments, and their securities may be more volatile and less liquid.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Risk of Investing in the United States. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

Securities Lending Risk. The Fund may engage in securities lending. Securities

lending involves the risk that the Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and

may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Provider or its agents will generally be borne by the Fund and its shareholders. For example, during a period where the Underlying Index contains incorrect constituents, the Fund would have market exposure to such constituents and would be underexposed to the Underlying Index’s other constituents. Such errors may negatively or positively impact the Fund and its shareholders.

corporate restructurings, fraudulent disclosures, credit deterioration of the issuer or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline. An issuer may also be subject to risks associated with the countries, states and regions in which the issuer resides, invests, sells products, or otherwise conducts operations.

Market Trading Risk

extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market.

Mid-Capitalization Companies Risk. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell shares of mid-capitalization companies. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments.

take into account the tax impact to shareholders of substitute payments for dividends when managing the Fund's securities lending program.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

healthcare companies are heavily dependent on patent protection. The expiration of a company’s patents may adversely affect that company’s profitability. Many healthcare companies are subject to extensive litigation based on product liability and similar claims. Healthcare companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the healthcare sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly, and such efforts ultimately may be unsuccessful. Companies in the healthcare sector may be thinly capitalized and may be susceptible to product obsolescence. In addition, a number of legislative proposals concerning healthcare have been considered by the U.S. Congress in recent years. It is unclear what proposals will ultimately be enacted, if any, and what effect they may have on companies in the healthcare sector.

Materials Sector Risk. Companies in the materials sector may be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical advances, labor relations, over-production, litigation and government regulations, among other factors. Companies in the materials sector are also at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

Real Estate Investment Risk. The Fund may invest in companies that invest in real estate (“Real Estate Companies”), such as real estate investment trusts (“REITs”) or real estate holding companies, which expose investors to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which Real Estate Companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments and is characterized by intense competition and periodic overbuilding. Many Real Estate Companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially increase the Fund’s losses. Rising interest rates could result in higher costs of capital for Real Estate Companies, which could negatively affect a Real Estate Company's ability to meet its payment obligations or its financing activity, and could decrease the market prices for REITs and for properties held by such REITs. In addition, to the extent a Real Estate Company has its own expenses, the Fund (and indirectly, its shareholders) will bear its proportionate share of such expenses.

Concentration Risk. Real Estate Companies may own a limited number of properties and concentrate their investments in a particular geographic region, industry or property type. Economic downturns affecting a particular region, industry or property type may lead to a high volume of defaults within a short period.

other properties or poor management. Equity REITs also can be affected by rising interest rates. Rising interest rates may cause investors to demand a high annual yield from future distributions that, in turn, could decrease the market prices for such REITs and for the properties held by such REITs. In addition, rising interest rates also increase the costs of obtaining financing for real estate projects. Because many real estate projects are dependent upon receiving financing, this could cause the value of the Equity REITs in which the Fund invests to decline.

Interest Rate Risk. Rising interest rates could result in higher costs of capital for Real Estate Companies, which could negatively affect a Real Estate Company’s ability to meet its payment obligations. Declining interest rates could result in increased prepayment on loans and require redeployment of capital in less desirable investments.

Leverage Risk. Real Estate Companies may use leverage (and some may be highly leveraged), which increases investment risk and the risks normally associated with debt financing and could adversely affect a Real Estate Company’s operations and market value in periods of rising interest rates. Financial covenants related to a Real Estate Company’s leveraging may affect the ability of the Real Estate Company to operate effectively. In addition, investments may be subject to defaults by borrowers and tenants. Leveraging may also increase repayment risk.

Liquidity Risk. Investing in Real Estate Companies may involve risks similar to those associated with investing in small-capitalization companies. Real Estate Company securities may be volatile. There may be less trading in Real Estate Company shares, which means that purchase and sale transactions in those shares could have a magnified impact on share price, resulting in abrupt or erratic price fluctuations. In addition, real estate is relatively illiquid and, therefore, a Real Estate Company may have a limited ability to vary or liquidate its investments in properties in response to changes in economic or other conditions.

Loan Foreclosure Risk. Real Estate Companies may foreclose on loans that the Real Estate Company originated and/or acquired. Foreclosure may generate negative publicity for the underlying property that affects its market value. In addition to length and expense, the validity of the terms of the applicable loan may not be enforced in foreclosure proceedings.

Operational Risk. Real Estate Companies are dependent upon management skills and may have limited financial resources. Real Estate Companies are generally not diversified and may be subject to heavy cash flow dependency, default by borrowers and self-liquidation. In addition, transactions between Real Estate Companies and their affiliates may be subject to conflicts of interest, which may adversely affect a Real Estate Company’s shareholders. A Real Estate Company may also have joint ventures in certain of its properties and, consequently, its ability to control decisions relating to such properties may be limited.

acts; eminent domain seizures; and casualty or condemnation losses. Real estate income and values also may be greatly affected by demographic trends, such as population shifts, changing tastes and values, increasing vacancies or declining rents resulting from legal, cultural, technological, global or local economic developments and changes in tax law.

Regulatory Risk. Real estate income and values may be adversely affected by applicable domestic and foreign laws (including tax laws). Government actions, such as tax increases, zoning law changes, reduced funding for schools, parks, garbage collection and other public services or environmental regulations also may have a major impact on real estate income and values.

Repayment Risk. The prices of Real Estate Company securities may drop because of the failure of borrowers to repay their loans, poor management, or the inability to obtain financing either on favorable terms or at all. If the properties in which Real Estate Companies invest do not generate sufficient income to meet operating expenses, including, where applicable, debt service, ground lease payments, tenant improvements, third-party leasing commissions and other capital expenditures, the income and ability of the Real Estate Companies to make payments of interest and principal on their loans will be adversely affected.

U.S. Tax Risk. Certain U.S. Real Estate Companies are subject to special U.S. federal tax requirements. A REIT that fails to comply with such tax requirements may be subject to U.S. federal income taxation, which may affect the value of the REIT and the characterization of the REIT’s distributions. The U.S. federal tax requirement that a REIT distributes substantially all of its net income to its shareholders may result in the REIT having insufficient capital for future expenditures. A REIT that successfully maintains its qualification may still become subject to U.S. federal, state and local taxes, including excise, penalty, franchise, payroll, mortgage recording, and transfer taxes, both directly and indirectly through its subsidiaries.

capital markets; face restrictions on operations and increased cost and delays attributable to environmental considerations and regulation; find that existing plants, equipment or products have been rendered obsolete by technological innovations; or be subject to increased costs because of the scarcity of certain fuels or the effects of man-made or natural disasters. Existing and future regulations or legislation may make it difficult for utility companies to operate profitably. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. There is no assurance that regulatory authorities will grant rate increases in the future or that such increases will be adequate to permit the payment of dividends on stocks issued by a utility company. Energy conservation and changes in climate policy may also have a significant adverse impact on the revenues and expenses of utility companies.

BFA and the other Affiliates are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA or one or more of the other Affiliates acts, or may act, as an investor, investment banker, research provider, investment manager, commodity pool operator, commodity trading advisor, financier, underwriter, adviser, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests in securities, currencies, commodities, derivatives and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA or an Affiliate performs or seeks to perform investment banking or other services. Specifically, the Fund may invest in securities of, or engage in other transactions with, companies with which an Affiliate has developed or is trying to develop investment banking relationships or in which an Affiliate has significant debt or equity investments or other interests. The Fund also may invest in securities of, or engage in other transactions with, companies for which an Affiliate provides or may in the future provide research coverage. An Affiliate may have business relationships with, and purchase, distribute or sell services or products from or to, distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates in connection with the Fund's portfolio investment transactions.

The Fund's activities may be limited because of regulatory restrictions applicable to one or more Affiliates and/or their internal policies designed to comply with such restrictions.

Shareholder Information

The Fund's spread may also be impacted by the liquidity of the underlying securities held by the Fund, particularly for newly launched or smaller funds or in instances of significant volatility of the underlying securities.

the Fund, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout each trading day by the national securities exchange on which the Fund's shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities or other assets and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities or other assets held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund's NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and price quotations obtained from broker-dealers and other market intermediaries that may trade in the portfolio securities or other assets held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the U.S. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, when there is a significant event subsequent to the most recent market quotation, or if the trading market on which a security is listed is suspended or closed and no appropriate alternative trading market is available. A “significant event” is deemed to occur if BFA determines, in its reasonable business judgment prior to or at the time of pricing the Fund’s assets or liabilities, that the event is likely to cause a material change to the closing market price of one or more assets or liabilities held by the Fund.

Dividends and Distributions

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, price movement and other costs and expenses related to cash transactions (which may, in certain instances, be based on a good faith estimate of transaction costs). Investors who use the services of a broker or other financial intermediary to acquire or dispose of Fund shares may pay fees for such services.

Approximate Value of a Creation Unit		Creation Unit Size		Standard Creation/ Redemption Transaction Fee		Maximum Additional Charge for Creations*		Maximum Additional Charge for Redemptions*
$9,351,500		50,000		$1,000		3.0%		2.0%

*	As a percentage of the net asset value per Creation Unit, inclusive, in the case of redemptions, of the standard redemption transaction fee.

iSHARES^® CORE S&P SMALL-CAP ETF

Ticker: IJR

Stock Exchange: NYSE Arca

Investment Objective

The iShares Core S&P Small-Cap ETF (the “Fund”) seeks to track the investment results of an index composed of small-capitalization U.S. equities.

Fees and Expenses

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

S-1

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P SmallCap 600 (the “Underlying Index”), which measures the performance of the small-capitalization sector of the U.S. equity market, as determined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). As of March 31, 2018, the Underlying Index included approximately 3% of the market capitalization of all publicly-traded U.S. equity securities. The securities in the Underlying Index are weighted based on the float-adjusted market value of their outstanding shares, have, as of March 31, 2018, a market capitalization between $400 million and $1.8 billion at time of entry, which may fluctuate depending on the overall level of the equity markets, and are selected by SPDJI for liquidity and industry group representation. The Underlying Index consists of securities from a broad range of industries. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the financials, industrials and information

technology industries or sectors. The components of the Underlying Index are likely to change over time.

S-2

futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, as well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

S-3

disruptions and negatively impact the Fund’s business operations, potentially resulting in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cyber security plans and systems of the Fund’s service providers, the Index Provider, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

S-4

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Securities Lending Risk. The Fund may engage in securities lending. Securities

Small-Capitalization Companies Risk. Compared to mid- and large-capitalization companies, small-capitalization companies may be less stable and more susceptible to adverse developments, and their securities may be more volatile and less liquid.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and

may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Market Trading Risk

extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market.

and may depend on a small number of essential personnel, making these companies more vulnerable to experiencing adverse effects due to the loss of personnel. Small-capitalization companies also normally have less diverse product lines than those of mid- or large-capitalization companies and are more susceptible to adverse developments concerning their products.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

technologies and other market developments. A number of issuers in the healthcare sector have recently merged or otherwise experienced consolidation. The effects of this trend toward consolidation are unknown and may be far-reaching. Many healthcare companies are heavily dependent on patent protection. The expiration of a company’s patents may adversely affect that company’s profitability. Many healthcare companies are subject to extensive litigation based on product liability and similar claims. Healthcare companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the healthcare sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly, and such efforts ultimately may be unsuccessful. Companies in the healthcare sector may be thinly capitalized and may be susceptible to product obsolescence. In addition, a number of legislative proposals concerning healthcare have been considered by the U.S. Congress in recent years. It is unclear what proposals will ultimately be enacted, if any, and what effect they may have on companies in the healthcare sector.

affected by conditions in the real estate rental market and by changes in the value of the properties they own. A decline in rental income may occur because of extended vacancies, limitations on rents, the failure to collect rents, increased competition from other properties or poor management. Equity REITs also can be affected by rising interest rates. Rising interest rates may cause investors to demand a high annual yield from future distributions that, in turn, could decrease the market prices for such REITs and for the properties held by such REITs. In addition, rising interest rates also increase the costs of obtaining financing for real estate projects. Because many real estate projects are dependent upon receiving financing, this could cause the value of the Equity REITs in which the Fund invests to decline.

Property Risk. Real Estate Companies may be subject to risks relating to functional obsolescence or reduced desirability of properties; extended vacancies due to economic conditions and tenant bankruptcies; property damage due to events such as earthquakes, hurricanes, tornadoes, rodent, insect or disease infestations and terrorist acts; eminent domain seizures; and casualty or condemnation losses. Real estate income and values also may be greatly affected by demographic trends, such as population shifts, changing tastes and values, increasing vacancies or declining rents resulting from legal, cultural, technological, global or local economic developments and changes in tax law.

to, or obtain services from, entities for which BFA or an Affiliate performs or seeks to perform investment banking or other services. Specifically, the Fund may invest in securities of, or engage in other transactions with, companies with which an Affiliate has developed or is trying to develop investment banking relationships or in which an Affiliate has significant debt or equity investments or other interests. The Fund also may invest in securities of, or engage in other transactions with, companies for which an Affiliate provides or may in the future provide research coverage. An Affiliate may have business relationships with, and purchase, distribute or sell services or products from or to, distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates in connection with the Fund's portfolio investment transactions.

The Fund's activities may be limited because of regulatory restrictions applicable to one or more Affiliates and/or their internal policies designed to comply with such restrictions.

Shareholder Information

not trade in the U.S. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

valuations and that may not be the prices at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

Dividends and Distributions

non-corporate shareholders, depending on whether their income exceeds certain threshold amounts. In addition, a 3.8% U.S. federal Medicare contribution tax is imposed on “net investment income,” including, but not limited to, interest, dividends, and net gain, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly) and of estates and trusts.

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

shareholder's cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a

DTC participant that has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund's SAI.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, price movement and other costs and expenses related to cash transactions (which may, in certain instances, be based on a good faith estimate of transaction costs). Investors who use the services of a broker or other financial intermediary to acquire or dispose of Fund shares may pay fees for such services.

Approximate Value of a Creation Unit		Creation Unit Size		Standard Creation/ Redemption Transaction Fee		Maximum Additional Charge for Creations*		Maximum Additional Charge for Redemptions*
$3,891,000		50,000		$1,500		3.0%		2.0%

*	As a percentage of the net asset value per Creation Unit, inclusive, in the case of redemptions, of the standard redemption transaction fee.

iSHARES^® CORE S&P TOTAL U.S. STOCK MARKET ETF

Ticker: ITOT

Stock Exchange: NYSE Arca

Investment Objective

The iShares Core S&P Total U.S. Stock Market ETF (the “Fund”) seeks to track the investment results of a broad-based index composed of U.S. equities.

Fees and Expenses

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P Total Market Index™ (TMI) (the “Underlying Index”), which is comprised of the common equities included in the S&P 500^® and the S&P Completion Index™. The Underlying Index consists of all U.S. common equities listed on the New York Stock Exchange (“NYSE”) (including NYSE Arca, Inc. (“NYSE Arca”) and NYSE MKT), the NASDAQ Global Select Market, the NASDAQ Global Market, the NASDAQ Capital Market and BATS Exchange, Inc. The securities in the Underlying Index are weighted based on the total float-adjusted market value of their outstanding shares. Securities with higher total float-adjusted market value have a larger representation in the Underlying Index. The S&P 500 measures the performance of the large-capitalization sector of the U.S. equity market. The S&P Completion Index measures the performance of the U.S. mid-, small- and micro-capitalization sector of the U.S. equity market. As of March 31, 2018, the S&P 500 and the S&P Completion Index included

approximately 80% and 20%, respectively, of the market capitalization of the Underlying Index. The Underlying Index includes large-, mid-, small- and micro-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the financials and information technology industries or sectors. The components of the Underlying Index are likely to change over time.

measures similar to those of an applicable underlying index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

The Underlying Index is a product of S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”), which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

capital requirements and recent or future regulation of any individual financial company, or of the financials sector as a whole, cannot be predicted.

subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large-capitalization companies has trailed the overall performance of the broader securities markets.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Passive Investment Risk. The Fund is not actively managed, and BFA generally

does not attempt to take defensive positions under any market conditions, including declining markets.

Average Annual Total Returns

(for the periods ended December 31, 2017)

	One Year	Five Years	Ten Years
(Inception Date: 1/20/2004)
Return Before Taxes	21.23%	15.62%	8.54%
Return After Taxes on Distributions¹	20.67%	15.08%	8.13%
Return After Taxes on Distributions and Sale of Fund Shares¹	12.36%	12.49%	6.89%
S&P Total Market Index^TM (TMI) (Index returns do not reflect deductions for fees, expenses, or taxes)²	21.16%	15.67%	8.65%

After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sales of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares in cases where the shares have decreased in value during the period. As a result, Fund returns after taxes on distributions and sales of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Index returns through December 20, 2015 reflect the performance of the S&P Composite 1500^®. Index returns beginning on December 21, 2015 reflect the performance of the S&P Total Market Index^TM (TMI), which, effective as of December 21, 2015, replaced the S&P Composite 1500^® as the underlying index of the Fund.

More Information About the Fund

substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and

may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to

the risk that BFA’s investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Trading Risk

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below the Fund’s most recent NAV. The NAV of

the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Fund's shares fluctuates continuously throughout trading hours based on both market supply of and demand for Fund shares and the underlying value of the Fund's portfolio holdings or NAV. As a result, the trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV, BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long term (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs). While the creation/redemption feature is designed to make it more likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund's NAV due to timing reasons, supply and demand imbalances and other factors. In addition, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants, or other market participants, and during periods of significant market volatility, may result in trading prices for shares of the Fund that differ significantly from its NAV. Authorized Participants may be less willing to create or redeem Fund shares if there is a lack of an active market for such shares or its underlying investments, which may contribute to the Fund’s shares trading at a premium or discount to NAV.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

mishandling of materials and a risk of loss from terrorism, political strife or natural disasters. Any such event could have serious consequences for the general population of the affected area and could have an adverse impact on the Fund’s portfolio and the performance of the Fund. Energy companies can be significantly affected by the supply of, and demand for, specific products (e.g., oil and natural gas) and services, exploration and production spending, government subsidization, world events and general economic conditions. Energy companies may have relatively high levels of debt and may be more likely than other companies to restructure their businesses if there are downturns in energy markets or in the global economy.

Mid-Capitalization Companies Risk. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, the

Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell shares of mid-capitalization companies. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments.

Small-Capitalization Companies Risk. Stock prices of small-capitalization companies may be more volatile than those of larger companies and, therefore, the Fund's share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by mid- or large-capitalization companies. Stock prices of small-capitalization companies are generally more vulnerable than those of mid- or large-capitalization companies to adverse business and economic developments. Securities of small-capitalization companies may be thinly traded, making it difficult for the Fund to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making these companies more vulnerable to experiencing adverse effects due to the loss of personnel. Small-capitalization companies also normally have less diverse product lines than those of mid- or large-capitalization companies and are more susceptible to adverse developments concerning their products.

Management

affiliates with respect to certain portfolio securities. In seeking to achieve the Fund's investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

For its investment advisory services to the Fund, BFA is paid a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.03%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Alan Mason has been employed by BFA as a portfolio manager since 1991. Mr. Mason has been a Portfolio Manager of the Fund since 2016.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. The investment activities of BFA and its affiliates (including BlackRock and The PNC Financial Services Group, Inc., and their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and the other Affiliates provide investment management services to other funds and discretionary managed accounts that may follow investment programs similar to that of the Fund. BFA and the other Affiliates are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA or one or more of the other Affiliates acts, or may act, as an investor, investment banker, research provider, investment manager, commodity pool operator, commodity trading advisor, financier, underwriter, adviser, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests in securities, currencies, commodities, derivatives and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA or an Affiliate performs or seeks to perform investment banking or other services. Specifically, the Fund may invest in securities of, or engage in other transactions with, companies with which an Affiliate has developed or is trying to develop investment banking relationships or in which an Affiliate has significant debt or equity investments or other interests. The Fund also may invest in securities of, or engage in other transactions with, companies for which an Affiliate provides or may in the future provide research coverage. An Affiliate may have business relationships with, and purchase, distribute or sell services or products

from or to, distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates in connection with the Fund's portfolio investment transactions.

The Fund's activities may be limited because of regulatory restrictions applicable to one or more Affiliates and/or their internal policies designed to comply with such restrictions.

The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P 900 Growth Index (the “Underlying Index”), which measures the performance of the large- and mid- capitalization growth sector of the U.S. equity market, as determined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). The Underlying Index is a subset of the S&P 900, which combines the S&P 500^® and the S&P MidCap 400^®, and consists of those stocks in the S&P 900 exhibiting strong growth characteristics, as determined by SPDJI. As of March 31, 2018, the Underlying Index represented approximately 55% of the total market capitalization of the S&P 900. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the consumer discretionary, health care and information technology industries or sectors. The components of the Underlying Index are likely to change over time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many

investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

the Fund track the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

Asset Class Risk. Securities and other assets in the Underlying Index or in the Fund's portfolio may underperform in comparison to the general financial

markets, a particular financial market or other asset classes.

Consumer Discretionary Sector Risk. The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers' disposable income, consumer preferences, social trends and marketing campaigns.

S-3

resulting in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cyber security plans and systems of the Fund’s service providers, the Index Provider, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Growth Securities Risk. The Fund invests in growth securities, which may be more volatile than other types of investments, may perform differently than the market as a whole and may underperform when compared to securities with different investment parameters. Under certain market conditions, growth securities have performed better during the later stages of economic recovery. Therefore, growth securities may go in and out of favor over time.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

A Further Discussion of Principal Risks

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, region, market, industry, group of industries, sector or asset class.

in which the Fund invests, the Index Provider, market makers or Authorized Participants. The Fund and its shareholders could be negatively impacted as a result.

Growth Securities Risk. Growth companies are companies whose earnings growth potential appears to be greater than the market in general and whose revenue growth is expected to continue for an extended period of time. Stocks of growth companies or “growth securities” have market values that may be more volatile than those of other types of investments. Under certain market conditions, growth securities have performed better during the later stages of economic recovery. Therefore, growth securities may go in and out of favor over time. Growth securities typically do not pay a dividend, which can help cushion stock prices in market downturns and reduce potential losses.

achieve, neither the Index Provider nor its agents provide any warranty or accept any liability in relation to the quality, accuracy or completeness of the Underlying Index or its related data, and they do not guarantee that the Underlying Index will be in line with the Index Provider’s methodology. BFA’s mandate as described in this Prospectus is to manage the Fund consistently with the Underlying Index provided by the Index Provider to BFA. BFA does not provide any warranty or guarantee against the Index Provider’s or any agent’s errors. Errors in respect of the quality, accuracy and completeness of the data used to compile the Underlying Index may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, particularly where the indices are less commonly used as benchmarks by funds or managers. Therefore, gains, losses or costs associated with errors of the Index Provider or its agents will generally be borne by the Fund and its shareholders. For example, during a period where the Underlying Index contains incorrect constituents, the Fund would have market exposure to such constituents and would be underexposed to the Underlying Index’s other constituents. Such errors may negatively or positively impact the Fund and its shareholders.

changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Financials Sector Risk. Companies in the financials sector are subject to extensive governmental regulation and intervention, which may adversely affect the scope of their activities, the prices they can charge, the amount of capital they must maintain and, potentially, their size. The extent to which the Fund may invest in a company that engages in securities-related activities or banking is limited by applicable law. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financials sector, including effects not intended by such regulation. Recently enacted legislation in the U.S. has relaxed capital requirements and other regulatory burdens on certain U.S. banks. While the effect of the legislation may benefit certain companies in the financials sector, increased risk taking by affected banks may also result in greater overall risk in the financials sector. The impact of changes in capital requirements, or recent or future regulation in various countries, on any individual financial company or on the financials sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financials sector more severely than those of investments outside this sector, including the risks associated with companies that operate with substantial financial leverage.

Companies in the financials sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Insurance companies, in particular, may be subject to severe price competition and/or rate regulation, which may have an adverse impact on their profitability. The financials sector is particularly sensitive to fluctuations in interest rates. The financials sector is also a target for cyber attacks, and may experience technology malfunctions and disruptions. In recent years, cyber attacks and technology malfunctions and failures have become increasingly frequent in this sector and have reportedly caused losses to companies in this sector, which may negatively impact the Fund.

The Fund also may invest in securities of, or engage in other transactions with, companies for which an Affiliate provides or may in the future provide research coverage. An Affiliate may have business relationships with, and purchase, distribute or sell services or products from or to, distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates in connection with the Fund's portfolio investment transactions.

The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the U.S. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the prices at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

Dividends and Distributions

taxable to you at long-term capital gain rates. Long-term capital gains and qualified dividend income are generally eligible for taxation at a maximum rate of 15% or 20% for non-corporate shareholders, depending on whether their income exceeds certain threshold amounts. In addition, a 3.8% U.S. federal Medicare contribution tax is imposed on “net investment income,” including, but not limited to, interest, dividends, and net gain, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly) and of estates and trusts.

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

capital gain dividends, are included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

iSHARES^® CORE S&P U.S. VALUE ETF

Ticker: IUSV

Stock Exchange: NASDAQ

Investment Objective

The iShares Core S&P U.S. Value ETF (the “Fund”) seeks to track the investment results of an index composed of large- and mid-capitalization U.S. equities that exhibit value characteristics.

Fees and Expenses

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

S-1

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P 900 Value Index (the “Underlying Index”), which measures the performance of the large- and mid-capitalization value sector of the U.S. equity market, as determined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). The Underlying Index is a subset of the S&P 900, which combines the S&P 500^® and the S&P MidCap 400^®, and consists of those stocks in the S&P 900 exhibiting strong value characteristics, as determined by SPDJI. As of March 31, 2018, the Underlying Index represented approximately 45% of the total market capitalization of the S&P 900. The Underlying Index may include large- and mid-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the financials industry or sector. The components of the Underlying Index are likely to change over time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many

investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

S-2

the Fund track the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

Asset Class Risk. Securities and other assets in the Underlying Index or in the Fund's portfolio may underperform in

comparison to the general financial markets, a particular financial market or other asset classes.

S-3

has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cyber security plans and systems of the Fund’s service providers, the Index Provider, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

S-4

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Securities Lending Risk. The Fund may engage in securities lending. Securities

Value Securities Risk. Securities issued by companies that may be perceived as undervalued may fail to appreciate for long periods of time and may never realize their full potential value. Value securities have generally performed better than non-value securities during periods of economic recovery. Value securities may go in and out of favor over time.

A Further Discussion of Principal Risks

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and

may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Market Trading Risk

Value Securities Risk. Value securities are those issued by companies that may be perceived as undervalued. Value securities may fail to appreciate for long periods of time and may never realize their full potential value. Value securities have generally performed better than non-value securities during periods of economic recovery. Value securities may go in and out of favor over time.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Implementation of these requirements may increase credit and other risks to the Fund.

Dividend Risk. There is no guarantee that issuers of the stocks held by the Fund will declare dividends in the future or that, if declared, such dividends will remain at current levels or increase over time.

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except the management fees, interest expenses, taxes, expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, distribution fees or expenses, litigation expenses and any extraordinary expenses. The Fund may incur “Acquired Fund Fees and Expenses.” Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred by investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund's prospectus (the “Prospectus”). BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees so that the Fund's total annual fund operating expenses after fee waiver is equal to the Acquired Fund Fees and Expenses attributable to the Fund's investment in the iShares JPX-Nikkei 400 ETF (“JPXN” or the “Underlying Fund”), after taking into account any fee waivers by JPXN through July 31, 2020. The contractual waiver may be terminated prior to July 31, 2020 only upon written agreement of the Trust and BFA.

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

Portfolio Turnover. The Fund and the Underlying Fund in which the Fund principally invests, the iShares JPX-Nikkei 400 ETF, may pay transaction costs, such as commissions, when they buy and sell securities (or “turn over” their portfolios). A higher portfolio turnover rate for the Fund or the Underlying Fund may indicate higher transaction costs and may cause the Fund or the Underlying Fund to incur increased expenses. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example (except costs to the Underlying Fund included as part of Acquired Fund Fees and Expenses), affect the Fund’s performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 11% of the average value of its portfolio. To the extent the Underlying Fund incurs costs from high portfolio turnover, such costs may have a negative effect on the performance of the Fund.

Principal Investment Strategies

The Fund seeks to track the investment results of the JPX-Nikkei 400 Net Total Return USD Hedged Index (the “Underlying Index”), which provides exposure to broad-based Japanese equities with the currency risk inherent

in the securities included in the Underlying Index hedged to the U.S. dollar on a monthly basis. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the consumer discretionary and industrials industries or sectors. The components of the Underlying Index are likely to change over time.

Currently, the Fund seeks to achieve its investment objective by investing a substantial portion of its assets in the Underlying Fund.

S-2

BFA uses a representative sampling indexing strategy to manage the Fund and the Underlying Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities or other instruments comprising an applicable underlying index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of an applicable underlying index. The Fund and the Underlying Fund may or may not hold all of the securities and other components of the applicable Underlying Index.

The Fund generally will invest at least 90% of its assets in the component securities (including indirect investments through the Underlying Fund) and other instruments of the Underlying Index and in investments that have economic characteristics that are substantially identical to the component securities of the Underlying Index (i.e., depositary receipts representing securities of the Underlying Index) and may invest up to 10% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, as well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. Components of the Underlying Index include equity securities and foreign currency forward contracts (both deliverable and non-deliverable) designed to hedge non-U.S. currency fluctuations against the U.S.

dollar. The notional exposure to foreign currency forward contracts (both deliverable and non-deliverable) generally will be a short position that hedges the currency risk of the equity portfolio. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The impact of the “hedging” component of the Underlying Index is calculated by assuming the sale of one-month currency forward contracts at the end of each month. The aggregate notional amount of currency forwards used to calculate the impact of the “hedging” component on index return equals the total value of index constituent securities that trade in each underlying non-USD currency at the end of each month, and is not adjusted intra-month based on movements in the value of the constituent equity securities. The Underlying Index may therefore be slightly “over-hedged” (if security values decline) or “under-hedged” (if security values increase) between month-end index rebalances.

In order to track the “hedging” component of the Underlying Index, the Fund enters into foreign currency forward contracts designed to offset the Fund’s exposure to the Japanese yen. A foreign currency forward contract is a contract between two parties to buy or sell a specified amount of a specific currency in the future at an agreed-upon exchange rate. The Fund’s exposure to foreign currency forward contracts is based on the aggregate exposure of the Fund to the Japanese yen. While this approach is designed to minimize the impact of currency fluctuations on Fund returns, it does not necessarily eliminate the Fund’s exposure to the Japanese yen. The

S-3

return of the foreign currency forward contracts may not perfectly offset the actual fluctuations in value between the Japanese yen and the U.S. dollar.

The Fund may also use non-deliverable forward (“NDF”) contracts to execute its hedging transactions. An NDF is a contract where there is no physical settlement of two currencies at maturity. Rather, based on the movement of the currencies and the contractually agreed upon exchange rate, a net cash settlement will be made by one party to the other in U.S. dollars.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

The Underlying Index is sponsored by Japan Exchange Group, Inc. and Tokyo Stock Exchange, Inc. (together, “JPX Group”) and Nikkei Inc. (the “Nikkei”) (collectively, the “Index Provider”), which are independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities and currency forwards in the Underlying Index and publishes information regarding the market value of the Underlying Index.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. The Fund is subject to certain risks, including the principal risks noted below (either directly or through its investments in the Underlying Fund), any of which may adversely affect the Fund's net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities and other assets in the Underlying Index or in the Fund's or the Underlying Fund's portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes.

Assets Under Management (AUM) Risk. From time to time, an Authorized Participant (as defined in the Creations and Redemptions section of this Prospectus), a third-party investor, the Fund’s adviser or an affiliate of the Fund’s adviser, or a fund may invest in the Fund and hold its investment for a specific period of time in order to facilitate commencement of the Fund’s operations or to allow the Fund to achieve size or scale. There can be no assurance that any such entity would not redeem its investment or that the size of the Fund would be maintained at such levels, which could negatively impact the Fund.

S-4

the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units (as defined in the Purchase and Sale of Fund Shares section of the Prospectus), Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for exchange-traded funds (“ETFs”), such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes.

eliminate losses, it can also reduce or eliminate gains. Hedges are sometimes subject to imperfect matching between the derivative and its reference asset, and there can be no assurance that the Fund’s hedging transactions will be effective.

In seeking to track the “hedging” component of the Underlying Index, the Fund invests in foreign currency forward contracts (which may include both physically-settled forward contracts and NDFs) designed to hedge the currency exposure of non-U.S. dollar denominated securities held in its portfolio (directly or indirectly through its investment in the Underlying Fund). NDFs may be less liquid than deliverable currency forward contracts and require the Fund to post variation margin to the counterparty, which can increase costs for the Fund. A lack of liquidity in NDFs of the hedged currency could result in the Fund being unable to structure its hedging transactions as intended. In addition, BFA may seek to limit the size of the Fund in order to attempt to reduce the likelihood of a situation where the Fund is unable to obtain sufficient liquidity in an underlying currency hedge to implement its investment objective.

S-5

to the Japanese yen may not be fully hedged at all times. In addition, because the Fund’s currency hedge is reset on a monthly basis, currency risk can develop or increase intra-month. Furthermore, while the Fund is designed to hedge against currency fluctuations, it is possible that a degree of currency exposure may remain even at the time a hedging transaction is implemented. As a result, the Fund may not be able to structure its hedging transactions as anticipated or its hedging transactions may not successfully reduce the currency risk included in the Fund’s portfolio. Because currency forwards are over-the-counter instruments, the Fund is subject to counterparty risk as well as market or liquidity risk with respect to the hedging transactions the Fund enters into. Currency hedging activity exposes the Fund to credit risk due to counterparty exposure. This risk will be higher to the extent that the Fund trades with a single counterparty or small number of counterparties.

The effectiveness of the Fund’s currency hedging strategy will in general be affected by the volatility of both the Underlying Index and the volatility of the U.S. dollar relative to the Japanese yen, measured on an aggregate basis. Increased volatility in either or both of the Underlying Index and the U.S. dollar relative to the Japanese yen will generally reduce the effectiveness of the Fund’s currency hedging strategy. The effectiveness of the Fund’s currency hedging strategy may also in general be affected by interest rates. Significant differences between U.S. dollar interest rates and foreign currency interest rates applicable to the Japanese yen may impact the effectiveness of the Fund’s currency hedging strategy.

Currency Risk. Because the Fund's and the Underlying Fund's NAVs are determined in U.S. dollars, the Fund's NAV could decline if the Japanese yen depreciates against the U.S. dollar and/or the Fund's attempt to hedge currency exposure to the Japanese yen is unsuccessful. Generally, an increase in the value of the U.S. dollar against the Japanese yen will reduce the value of a security denominated in the Japanese yen. In addition, fluctuations in the exchange rates of currencies could affect the economy or particular business operations of companies in a geographic region, including securities in which the Fund or the Underlying Fund invests, causing an adverse impact on the Fund’s or the Underlying Fund’s investments in the affected region and the U.S. As a result, investors have the potential for losses regardless of the length of time they intend to hold Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the Fund's NAV may change quickly and without warning.

Cyber Security Risk. Failures or breaches of the electronic systems of the Fund or the Underlying Fund, the Fund's or the Underlying Fund's adviser, distributor, or other service providers, market makers, Authorized Participants, hedging counterparties to the Fund or the issuers of securities in which the Fund or the Underlying Fund invests have the ability to cause disruptions and negatively impact the Fund’s business operations, potentially resulting in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such

S-6

plans and systems. Furthermore, the Fund cannot control the cyber security plans and systems of the Fund’s service providers, the Index Provider, market makers, Authorized Participants, hedging counterparties to the Fund or issuers of securities in which the Fund or the Underlying Fund invests.

Derivatives Risk. The Fund’s or Underlying Fund's use of derivatives may reduce the Fund’s or Underlying Fund's returns or increase volatility. Volatility is defined as the characteristic of a security, a currency, an index or a market to fluctuate significantly in price within a short time period. Derivatives may also be subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation. Counterparty risk for OTC derivatives is generally higher than that for derivatives traded on an exchange or through a clearing house. A risk of the Fund’s or Underlying Fund's use of derivatives is that the fluctuations in their values may not correlate perfectly with the value of the underlying asset, the performance of the asset class to which the Fund seeks exposure or the performance of the overall markets. The possible lack of a liquid secondary market for derivatives and the resulting inability of the Fund to sell or otherwise close a derivatives position could expose the Fund to losses and could make derivatives more difficult for the Fund to value accurately. The Fund could also suffer losses related to its derivatives positions as a result of unanticipated market movements, or movements between the time of periodic reallocations of Fund assets, which losses are potentially unlimited. Certain derivatives may give rise to a form of leverage and may expose the Fund to

greater risk and increase its costs. The impact of U.S. and global regulation of derivatives may make derivatives more costly, may limit the availability of derivatives, may delay or restrict the exercise by the Fund of termination rights or remedies upon a counterparty default under derivatives held by the Fund (which could result in losses), or may otherwise adversely affect the value or performance of derivatives.

Geographic Risk. A natural disaster could occur in Japan, which could adversely affect the economy or the business operations of companies in Japan, causing an adverse impact on the Fund's investments in Japan.

S-7

and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders.

Investment in Underlying Fund Risk. The Fund expects to invest a substantial portion of its assets in the Underlying Fund, so the Fund’s investment performance is likely to be directly related to the performance of the Underlying Fund. The Fund’s NAV will change with changes in the value of the Underlying Fund and other instruments in which the Fund invests based on their market valuations. An investment in the Fund will entail more costs and expenses than a direct investment in the Underlying Fund, including as a result of the currency hedging activity conducted by the Fund.

As the Fund’s allocation to the Underlying Fund changes from time to time, or to the extent that the expense ratio of the Underlying Fund changes, the weighted average operating expenses borne by the Fund may increase or decrease.

Issuer Risk. The performance of the Fund depends on the performance of individual securities and other instruments to which the Fund and the Underlying Fund have exposure. Changes in the financial condition or credit rating of an issuer of those securities or counterparty on other

instruments may cause the value of the securities or instruments to decline.

Lack of Natural Resources Risk. The Fund and Underlying Fund invest in Japan, which has few natural resources. Any fluctuation or shortage in the commodity markets could have a negative impact on Japanese securities, which could reduce the possibility of appreciation or a positive impact on the currency, which in turn could reduce the benefit of the currency hedge entered into by the Fund.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund and the Underlying Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Market Trading Risk. The Fund and the Underlying Fund face numerous market trading risks, including the potential lack of an active market for their shares, losses from trading in secondary markets, losses due to ineffective currency hedges, periods of high volatility and disruptions in the

S-8

creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S AND THE UNDERLYING FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund or the Underlying Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s or the Underlying Fund's shares trade is open, there are likely to be deviations between the current price of such an underlying security and the last quoted price for the underlying security (i.e., the Fund’s or the Underlying Fund's quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s or the Underlying Fund's NAV that may be greater than those experienced by other ETFs.

may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times. The Fund and the Underlying Fund are specifically exposed to Asian Economic Risk.

Operational Risk. The Fund and the Underlying Fund are exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s or the Underlying Fund's service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund, the Underlying Fund and BFA seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Passive Investment Risk. The Fund and the Underlying Fund are not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Reliance on Trading Partners Risk. The Fund and the Underlying Fund invest in Japan, which is heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund's investments. Through its portfolio companies' trading partners, the Fund and the Underlying Fund are specifically exposed to Asian Economic Risk, European Economic Risk and U.S. Economic Risk.

S-9

generally remained low relative to other advanced economies, and it may remain low in the future. In addition, Japan is subject to the risk of natural disasters, such as earthquakes, volcanic eruptions, typhoons and tsunamis, which could negatively affect the Fund or the Underlying Fund. Japan’s relations with its neighbors have at times been strained, and strained relations may cause uncertainty in the Japanese markets and adversely affect the overall Japanese economy.

Security Risk. Japan has experienced security concerns, such as terrorism and strained international relations. Incidents involving Japan or the region's security may cause uncertainty in its markets and may adversely affect the Japanese economy and the Fund's or the Underlying Fund's investments.

Small Fund Risk. When the Fund’s size is small, the Fund may experience low trading volume and wide bid/ask spreads. In addition, the Fund may face the risk of being delisted if the Fund does not meet certain conditions of the listing exchange. If the Fund were to be required to delist from the listing exchange, the value of the Fund may rapidly decline and performance may be negatively impacted. In addition, any resulting liquidation of the Fund could cause the Fund to incur elevated

transaction costs for the Fund and negative tax consequences for its shareholders.

Tax Risk. Because the Fund invests in the Underlying Fund, the Fund’s realized losses on sales of shares of the Underlying Fund may be indefinitely or permanently deferred as “wash sales.” Distributions of short-term capital gains by the Underlying Fund will be recognized as ordinary income by the Fund and would not be offset by the Fund’s capital loss carryforwards, if any. Capital loss carryforwards of the Underlying Fund, if any, would not offset net capital gains of the Fund. Each of these effects is caused by the Fund’s investment in the Underlying Fund and may result in distributions to Fund shareholders being of higher magnitude and less likely to qualify for lower capital gain tax rates than if the Fund were to invest directly in the securities and other instruments comprising the Underlying Index. The Fund invests in derivatives. The federal income tax treatment of a derivative may not be as favorable as a direct investment in an underlying asset. Derivatives may produce taxable income and taxable realized gain. Derivatives may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than as capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. In addition, the tax treatment of certain derivatives is unsettled and may be subject to future legislation, regulation or administrative pronouncements issued by the U.S. Internal Revenue Service (“IRS”).

S-10

Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities (including shares of the Underlying Fund) and other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences (including, as applicable, differences between a security’s price at the local market close and the Fund’s valuation of a security at the time of calculation of the Fund’s NAV), differences in transaction and hedging costs and forward rates achieved, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or other distributions, interest, tax gains or losses, changes to the Underlying Index and the cost to the Fund of complying with various new or existing regulatory requirements. These risks may be heightened during times of increased market volatility or other unusual market conditions in the affected securities and/or foreign exchange markets. In addition, tracking error may result because the Fund incurs fees and expenses, while the Underlying Index does not, and because the Fund accepts creations and redemptions during time periods between which it is able to adjust its currency hedges, whereas the Underlying Index does not adjust its hedging during these periods. To the extent that the Fund seeks its investment objective through investments in the Underlying Fund, the Fund may experience increased tracking error. The potential for increased tracking error may result from investments in the Underlying Fund due to, among other things, differences in the composition of the investment portfolio of the Underlying Fund as compared to the index tracked by the Underlying Fund and differences in the

timing of the Fund’s valuation of: (i) the Underlying Fund and the currency forward contracts (each valued as of the close of the New York Stock Exchange (“NYSE”), typically 4:00 p.m., Eastern Time), (ii) the valuation of the securities in the Underlying Index (generally valued as of each security’s local market close) and (iii) the currency forward contracts included in the Underlying Index (generally valued at 4:00 p.m., London time).

Valuation Risk. The price the Fund and the Underlying Fund could receive upon the sale of a security or unwind of a financial instrument or other asset may differ from the Fund's or the Underlying Fund's valuation of the security, instrument or other asset and from the value used by the Underlying Index, particularly for securities or other instruments that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other instruments in the Fund's or the Underlying Fund's portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund's or the Underlying Fund's shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund or the Underlying Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund or the Underlying Fund not fair-valued securities or used a different valuation methodology. The Fund’s or the Underlying Fund's ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

More Information About the Fund

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a currency hedged securities index that may not be representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. The Fund may be exposed to these risks directly or indirectly through the Fund's investments in the Underlying Fund. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asian Economic Risk. Many Asian economies have experienced rapid growth and industrialization in recent years, but there is no assurance that this growth rate will be maintained. Other Asian economies, however, have experienced high inflation, high unemployment, currency devaluations and restrictions, and over-extension of credit. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia. Any adverse event in the Asian markets may have a significant adverse effect on some or all of the economies of the countries in which the Fund or the Underlying Fund invests. Many Asian countries are subject to political risk, including political instability, corruption and regional conflict with neighboring countries. North Korea and South Korea each have substantial military capabilities, and historical tensions between the two countries present the risk of war. Escalated tensions involving the two countries and any outbreak of hostilities between the two countries, or even the threat of an outbreak of hostilities, could have a severe adverse effect on the entire Asian region. In addition, many Asian countries are subject to social and labor risks associated with demands for improved political, economic and social conditions. These risks, among others, may adversely affect the value of the Fund’s or the Underlying Fund's investments.

industries, groups of industries, markets, asset classes or sectors. Various types of securities, currencies and indexes may experience cycles of outperformance and underperformance in comparison to the general financial markets depending upon a number of factors including, among other things, inflation, interest rates, productivity, global demand for local products or resources, and regulation and governmental controls. This may cause the Fund to underperform other investment vehicles that invest in different asset classes.

Assets Under Management (AUM) Risk. From time to time, an Authorized Participant, a third-party investor, the Fund’s adviser or an affiliate of the Fund’s adviser, or a fund may invest in the Fund and hold its investment for a specific period of time in order to facilitate commencement of the Fund’s operations or to allow the Fund to achieve size or scale. There can be no assurance that any such entity would not redeem its investment or that the size of the Fund would be maintained at such levels, which could negatively impact the Fund.

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's or the Underlying Fund's investments are concentrated in the securities of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

Currency Hedging Risk. When a derivative is used as a hedge against a position that the Fund holds, any loss generated by the derivative generally should be substantially offset by gains on the hedged investment, and vice versa. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. Hedges are sometimes subject to imperfect matching between the derivative and its reference asset, and there can be no assurance that the Fund’s hedging transactions will be effective. In seeking to track the “hedging” component of the Underlying Index, the Fund invests in foreign currency forward contracts, (which may include both physically-settled forward contracts and NDFs) designed to hedge the currency exposure of non-U.S. dollar denominated securities held in its portfolio (directly or indirectly through its investment in the Underlying Fund). NDFs may be less liquid than deliverable currency forward contracts and require the Fund to post variation margin to the counterparty, which can increase costs for the Fund. A lack of liquidity in NDFs of the hedged currency could result in the Fund being unable to structure its hedging transactions as intended. In addition, BFA may seek to limit the size of the Fund in order to attempt to reduce the likelihood of a situation where the Fund is unable to obtain sufficient liquidity in an underlying currency hedge to implement its investment objective.

Currency forward contracts, including NDFs, do not eliminate movements in the value of non-U.S. currencies and securities but rather allow the Fund to establish a fixed rate of exchange for a future point in time. Exchange rates may be volatile and may change quickly and unpredictably in response to both global economic developments and economic conditions in a geographic region in which the Fund invests. In addition, in order to minimize transaction costs, or for other reasons, the Fund’s exposure to the Japanese yen may not be fully hedged at all times or the hedge may not be effective due to counterparty failures or otherwise. Governments from time to time may intervene in the currency markets to influence prices and may adopt policies designed to influence foreign exchange rates with respect to their currency. Because the Fund’s currency hedge is reset on a monthly basis, currency risk can develop or increase intra-month. Furthermore, while the Fund is designed to hedge against currency fluctuations, it is possible that a degree of currency exposure may remain even at the time a hedging transaction is implemented. As a result, the Fund may not be able to structure its hedging transactions as anticipated or its hedging transactions may not successfully reduce the currency risk included in the Fund’s portfolio in a way that tracks the Underlying Index. Because currency forwards are over-the-counter instruments, the Fund is subject to counterparty risk as well as market or liquidity risk with respect to the hedging transactions the Fund enters into. Currency hedging activity exposes the Fund to credit risk due to counterparty exposure. This risk will be higher to the extent that the Fund trades with a single counterparty or small number of counterparties. In addition, the Fund’s currency hedging activities may involve frequent trading of currency instruments, which may increase transaction costs and cause the Fund’s return to deviate from the Underlying Index.

There is no assurance that the Fund’s strategy will be effective in hedging fluctuations in the value of the Japanese yen against the U.S. dollar. The effectiveness of the Fund’s currency hedging strategy will in general be affected by the volatility of both the Underlying Index and the volatility of the U.S. dollar relative to the Japanese yen, measured on an aggregate basis. Increased volatility in either or both of the Underlying

Index and the U.S. dollar relative to the Japanese yen will generally reduce the effectiveness of the Fund’s currency hedging strategy. The effectiveness of the Fund’s currency hedging strategy may also be affected by interest rates. Significant differences between U.S. dollar interest rates and foreign currency interest rates applicable to the Japanese yen may impact the effectiveness of the Fund’s currency hedging strategy. In addition, the currency hedging carried out by the Fund may result in lower returns than those generated through direct investments in the securities comprising the Underlying Index or in the index tracked by the Underlying Fund when the local currency appreciates against the U.S. dollar.

Investors, such as the Fund, seeking to trade in foreign currencies may have limited access to certain currency markets due to a variety of factors, including government regulations, adverse tax treatment, exchange controls, currency convertibility issues and lack of market liquidity. These limitations and restrictions may impact the availability, liquidity and pricing of the financial instruments that are necessary for the Fund to hedge exposure to the currency markets. If the Fund’s ability to enter into contracts to purchase or sell the Japanese yen is impaired, the Fund may not be able to achieve its investment objective. In addition, investments in currency forwards expose the Fund to the risks described under “Derivatives Risk.”

Currency Risk. Because the Fund's and the Underlying Fund's NAVs are determined on the basis of the U.S. dollar, investors may lose money if the Japanese yen depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency and/or the Fund’s attempt to hedge currency exposure to the Japanese yen is unsuccessful. Similarly, because the Fund seeks to hedge currency risk in accordance with the Underlying Index, investors may not share in appreciation in the securities comprising the Underlying Index to the extent that such appreciation is due to increases in the value of the underlying currency. In addition, fluctuations in the exchange rates of currencies could affect the economy or particular business operations of companies in a geographic region in which the Fund or the Underlying Fund invests, causing an adverse impact on the Fund’s or the Underlying Fund’s investments in the affected region and the U.S. that is separate from the value of the underlying currency and, therefore, unmitigated by the hedging strategy used by the Fund. As a result, investors in the Fund have the potential for losses regardless of the length of time they intend to hold Fund shares and regardless of the effectiveness of the Fund’s currency hedging transactions. The performance of the Fund may be materially better or worse than the performance of the Underlying Fund due primarily to the Fund's attempt to hedge currency exposure. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the Fund’s NAV may change quickly and without warning.

investment in such portfolio companies to lose value. Unlike many other types of risks faced by the Fund and the Underlying Fund, these risks typically are not covered by insurance. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber incidents include, but are not limited to, gaining unauthorized access to digital systems (e.g., through “hacking” or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cyber attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make network services unavailable to intended users). Cyber security failures by or breaches of the systems of the Fund’s or the Underlying Fund's adviser, distributor and other service providers (including, but not limited to, index providers, fund accountants, custodians, transfer agents and administrators), market makers, Authorized Participants, hedging counterparties to the Fund or the issuers of securities in which the Fund or the Underlying Fund invest, have the ability to cause disruptions and impact business operations, potentially resulting in: financial losses, interference with the Fund’s or the Underlying Fund's ability to calculate its NAV, disclosure of confidential trading information, impediments to trading, submission of erroneous trades or erroneous creation or redemption orders, the inability of the Fund, the Underlying Fund or their service providers to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. In addition, cyber attacks may render records of Fund assets and transactions, shareholder ownership of Fund shares, and other data integral to the functioning of the Fund or the Underlying Fund inaccessible or inaccurate or incomplete. Substantial costs may be incurred by the Fund or the Underlying Fund in order to resolve or prevent cyber incidents in the future. While the Fund and the Underlying Fund have established business continuity plans in the event of, and risk management systems to prevent, such cyber attacks, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified and that prevention and remediation efforts will not be successful. Furthermore, the Fund cannot control the cyber security plans and systems put in place by service providers to the Fund, issuers in which the Fund invests, the Index Provider, hedging counterparties to the Fund, market makers or Authorized Participants. The Fund and its shareholders could be negatively impacted as a result.

losses and could make derivatives more difficult for the Fund to value accurately. The Fund could also suffer losses related to its derivatives positions as a result of unanticipated market movements, or movements between the time of periodic reallocations of Fund assets, which losses are potentially unlimited. Certain derivatives may give rise to a form of leverage and may expose the Fund to greater risk and increase its costs. The impact of U.S. and global regulation of derivatives may make derivatives more costly, may limit the availability of derivatives, may delay or restrict the exercise by the Fund of termination rights or remedies upon a counterparty default under derivatives held by the Fund (which could result in losses), or may otherwise adversely affect the value or performance of derivatives.

Equity Securities Risk. The Fund and the Underlying Fund each invest in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes. The Underlying Index is comprised of common stocks, which generally subject their holders to more risks than holders of preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

European Economic Risk. The European Union (the “EU”) requires compliance by member states with restrictions on inflation rates, deficits, interest rates and debt levels, as well as fiscal and monetary controls, each of which may significantly affect every country in Europe, including those countries that are not members of the EU. Changes in imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro (the common currency of certain EU countries), the default or threat of default by an EU member state on its sovereign debt and/or an economic recession in an EU member state may have a significant adverse effect on the economies of EU member states and their trading partners. The European financial markets have historically experienced volatility and adverse trends due to concerns about economic downturns or rising government debt levels in several European countries, including, but not limited to, Austria, Belgium, Cyprus, France, Greece, Ireland, Italy, Portugal, Spain and Ukraine. These events have adversely affected the exchange rate of the euro and may continue to significantly affect European countries.

Responses to financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest, may limit future growth and economic recovery or may have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. In a referendum held on June 23, 2016, the United Kingdom (the “U.K.”) resolved to leave the EU. The referendum may introduce significant uncertainties and instability in the financial markets as the U.K. negotiates its exit from the EU. Although the precise timeframe for the U.K.’s withdrawal is uncertain, on March 29, 2017, the U.K. initiated the withdrawal process by sending a formal notice of the country’s intention to withdraw

from the EU. An agreement has been reached between the U.K. and the EU to continue negotiations on the U.K.’s exit from the EU. The outcome of negotiations remain uncertain.

Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

Geographic Risk. The market in which the Fund invests is located in a part of the world that has historically been prone to natural disasters such as earthquakes, volcanoes and tsunamis. Any natural disaster could have a significant adverse impact on the Japanese economy.

additional ad hoc rebalances carried out by the Index Provider or its agents to the Underlying Index may increase the costs to and the tracking error risk of the Fund.

Similar risks exist for the Underlying Fund in tracking its benchmark, which may result in the Fund's performance deviating from the return of the Underlying Index.

Investment in Underlying Fund Risk. The Fund expects to invest a substantial portion of its assets in the Underlying Fund, so the Fund’s investment performance is likely to be directly related to the performance of the Underlying Fund. The Fund may also invest in other funds, including money market funds. The Fund’s NAV will change with changes in the value of the Underlying Fund and other instruments in which the Fund invests based on their market valuations. An investment in the Fund will entail more direct and indirect costs and expenses than a direct investment in the Underlying Fund, including as a result of the currency hedging activity conducted by the Fund. For example, the Fund indirectly pays a portion of the expenses (including operating expenses and management fees) incurred by the Underlying Fund, although some of such fees will be offset by the fee waiver by BFA.

An investor in the Fund may receive taxable gains from portfolio transactions by the Underlying Fund, as well as taxable gains from transactions in shares of the Underlying Fund held by the Fund. The Fund and the Underlying Fund may also hold common portfolio securities.

As the Fund's allocation to the Underlying Fund changes from time to time, or to the extent that the expense ratio of the Underlying Fund changes, the weighted average operating expenses borne by the Fund may increase or decrease.

The Fund seeks to hedge the currency exposure of the instruments held by the Underlying Fund. The indirect nature of the holdings may make the hedging more difficult to achieve, and the Fund may be unable to accurately hedge currency exposure inherent in the Underlying Fund.

Issuer Risk. The performance of the Fund depends on the performance of individual securities and other instruments to which the Fund or the Underlying Fund has exposure. Any issuer of these securities or counterparty on other instruments may perform poorly, causing the value of its securities or instruments to decline. Poor

performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures, credit deterioration of the issuer or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline. An issuer may also be subject to risks associated with the countries, states and regions in which the issuer resides, invests, sells products, or otherwise conducts operations.

Lack of Natural Resources Risk. Japan is an island state with few natural resources and limited land area and is reliant on imports for its commodity needs. Any fluctuations or shortages in the commodity markets could have a negative impact on the Japanese economy.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities and other instruments not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund and the Underlying Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. The value of a security, asset or other instrument may decline due to changes in general market conditions, economic trends or events that are not specifically related to the issuer of the security or asset, or factors that affect a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class. During a general market downturn, multiple asset classes may be negatively affected. Changes in market conditions and interest rates generally do not have the same impact on all types of securities and instruments.

Market Trading Risk

Absence of Active Market. Although shares of the Fund and the Underlying Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained by market makers or Authorized Participants.

Fund's shares may be less actively traded in certain markets than in others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund or Underlying Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund or the Underlying Fund may trade in the secondary market at times when the Fund or the Underlying Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund or the Underlying Fund accepts purchase and redemption orders. If the Fund purchases shares of the Underlying Fund at a time when the market price of Underlying Fund shares is at a premium to their NAV or sells Underlying Fund shares when their market price is at a discount to their NAV, the Fund may incur losses.

Secondary market trading in Fund or Underlying Fund shares may be halted by a stock exchange because of market conditions or for other reasons. In addition, trading in Fund or Underlying Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market.

Shares of the Fund and the Underlying Fund May Trade at Prices Other Than NAV. Shares of the Fund and the Underlying Fund each trade on stock exchanges at prices at, above or below the Fund’s most recent NAV. The NAV of the Fund and the Underlying Fund are calculated at the end of each business day and fluctuate with changes in the market value of the Fund’s or the Underlying Fund's holdings. The trading price of each of the Fund's and the Underlying Fund's shares fluctuates continuously throughout trading hours based on both market supply of and demand for their shares and the underlying value of their portfolio holdings or NAV. As a result, the trading prices of the Fund’s and the Underlying Fund's shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S OR THE UNDERLYING FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV, BFA believes that large discounts or premiums to the NAV of the Fund or the Underlying Fund, as applicable, are not likely to be sustained over the long term (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs). However, BFA may seek to limit the size of the Fund in order to attempt to mitigate the likelihood of a situation where the Fund is unable to obtain sufficient liquidity in the Japanese yen hedge to implement its investment objective, including by recommending that the Fund limit purchases of Fund shares through Creation Unit transactions. If the Fund elects to impose limitations on creation transactions, Fund

shares may be more likely to trade at a premium to NAV in the secondary market. While the creation/redemption feature is designed to make it more likely that the Fund’s or the Underlying Fund's shares normally will trade on stock exchanges at prices close to the Fund’s or the Underlying Fund's next calculated NAV, exchange prices are not expected to correlate exactly with the NAV due to timing reasons, supply and demand imbalances and other factors. In addition, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants, or other market participants, and during periods of significant market volatility, may result in trading prices for shares of the Fund or the Underlying Fund that differ significantly from their respective NAV. Authorized Participants may be less willing to create or redeem Fund or Underlying Fund shares if there is a lack of an active market for such shares or its underlying investments, which may contribute to the Fund’s or Underlying Fund's shares trading at a premium or discount to NAV.

Mid-Capitalization Companies Risk. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, the Fund’s or the Underlying Fund's respective share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund or the Underlying Fund to buy and sell shares of mid-capitalization companies. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund or the Underlying Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s or the Underlying Fund's shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s or the Underlying Fund's quote from the closed foreign market). These

deviations could result in premiums or discounts to the Fund’s or the Underlying Fund's NAV that may be greater than those experienced by other ETFs.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks of investing in the markets where such issuers are located, including heightened risks of inflation, nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund or the Underlying Fund may be subject to increased risk of loss caused by any of the factors listed below:

■	Lower levels of liquidity and market efficiency;
■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;
■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements; and

■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the U.S.

Passive Investment Risk. The Fund and the Underlying Fund are not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities and other instruments included in, or representative of, the Underlying Index, regardless of their investment merits. BFA generally does not attempt to invest the Fund's assets in defensive positions under any market conditions, including declining markets.

Reliance on Trading Partners Risk. The Japanese economy is heavily dependent on international trade and has been adversely affected by trade tariffs, other protectionist measures and rising commodity prices. Japanese economic growth has generally been dependent on the U.S. and Chinese economies, with trade increasing with China in recent years.

Risk of Investing in Japan. Japan may be subject to political, economic, nuclear, and labor risks, among others. Any of these risks, individually or in the aggregate, can impact an investment made in Japan.

Economic Risk. The growth of Japan's economy has recently lagged that of its Asian neighbors and other major developed economies. Since 2000, Japan’s economic growth rate has generally remained low relative to other advanced economies, and it may remain low in the future. The Japanese economy is heavily dependent on international trade and has been adversely affected in the past by trade tariffs, other protectionist measures, competition from emerging economies and the economic conditions of its trading partners. Japan is also heavily dependent on oil and other commodity imports, and higher commodity prices could therefore have a negative impact on the Japanese economy.

Political Risk. Historically, Japan has had unpredictable national politics and may experience frequent political turnover. Future political developments may lead to changes in policy that might adversely affect the Fund’s or the Underlying Fund's investments. In addition, China has become an important trading partner with Japan. Japan's political relationship with China, however, is strained and delicate. Should political tension increase, it could adversely affect the Japanese economy and destabilize the region as a whole.

Large Government Debt Risk. The Japanese economy faces several concerns, including a financial system with large levels of nonperforming loans, over-leveraged corporate balance sheets, extensive cross-ownership by major corporations, a changing corporate governance structure, and large government deficits. These issues may cause a slowdown of the Japanese economy.

Currency Risk. The Japanese yen has fluctuated widely at times, and any increase in its value may cause a decline in exports that could weaken the Japanese economy. The Japanese government has, in the past, intervened in the currency markets to attempt to maintain or reduce the value of the yen. Japanese intervention in the currency markets could cause the value of the yen to fluctuate sharply and unpredictably and could cause losses to investors.

Nuclear Energy Risk. The nuclear power plant catastrophe in Japan in March 2011 may have long-term effects on the Japanese economy and its nuclear energy industry, the extent of which are currently unknown.

Labor Risk. Japan has an aging workforce and has experienced a significant population decline in recent years. Japan’s labor market appears to be undergoing fundamental structural changes, as a labor market traditionally accustomed to lifetime employment adjusts to meet the need for increased labor mobility, which may adversely affect Japan’s economic competitiveness.

Security Risk. Japan's relations with its neighbors, particularly China, North Korea,

South Korea and Russia, have at times been strained due to territorial disputes, historical animosities and defense concerns. Most recently, the Japanese government has shown concern over the increased nuclear and military activity by North Korea and China. Strained relations may cause uncertainty in the Japanese markets and adversely affect the overall Japanese economy, particularly in times of crisis.

Securities Lending Risk. The Fund and the Underlying Fund may engage in securities lending. Securities lending involves the risk that the Fund or the Underlying Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund or the Underlying Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund or the Underlying Fund. BlackRock Institutional Trust Company, N.A., the Fund's securities lending agent, will take into account the tax impact to shareholders of substitute payments for dividends when managing the Fund's securities lending program.

Security Risk. Japan's relations with its neighbors, particularly China, North Korea, South Korea and Russia, have at times been strained due to territorial disputes, historical animosities and defense concerns. Most recently, the Japanese government has shown concern over the increased nuclear and military activity by North Korea and China. Strained relations may cause uncertainty in the Japanese markets and adversely affect the overall Japanese economy and the Fund's and the Underlying Fund's investments in times of crisis.

Tax Risk. Because the Fund invests in the Underlying Fund, the Fund’s realized losses on sales of shares of the Underlying Fund may be indefinitely or permanently deferred as “wash sales.” Distributions of short-term capital gains by the Underlying Fund will be recognized as ordinary income by the Fund and would not be offset by the Fund’s capital loss carryforwards, if any. Capital loss carryforwards of the Underlying Fund, if any, would not offset net capital gains of the Fund. Each of these effects is caused by the Fund’s investment in the Underlying Fund and may result in distributions to Fund shareholders being of higher magnitudes and less likely to qualify for lower capital gain tax rates than if the Fund were to invest directly in the securities and other instruments comprising the Underlying Index. The Fund invests in derivatives. The federal income tax treatment of a derivative may not be as favorable as a direct investment in an underlying asset. Derivatives may produce taxable income and taxable realized gain. Derivatives may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund’s distributions may be treated as ordinary income rather than as capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Internal

Revenue Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. Income from swaps is generally taxable. In addition, the tax treatment of certain derivatives, such as swaps, is unsettled and may be subject to future legislation, regulation or administrative pronouncements issued by the IRS.

Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities (including shares of the Underlying Fund) and other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences (including, as applicable, differences between a security’s price at the local market close and the Fund’s valuation of a security at the time of calculation of the Fund’s NAV), differences in transaction and hedging costs and forward rates achieved, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or other distributions, tax gains or losses, changes to the Underlying Index and the cost to the Fund of complying with various new or existing regulatory requirements. These risks may be heightened during times of increased market volatility or other unusual market conditions in the affected securities and/or foreign exchange markets. In addition, tracking error may result because the Fund incurs fees and expenses, while the Underlying Index does not, and because the Fund accepts creations and redemptions during time periods between which it is able to adjust its currency hedges, whereas the Underlying Index does not adjust its hedging during these periods. To the extent that the Fund seeks its investment objective through investments in the Underlying Fund, the Fund may experience increased tracking error. The potential for increased tracking error may result from investments in the Underlying Fund due to, among other things, differences in the composition of the investment portfolio of the Underlying Fund as compared to the index tracked by the Underlying Fund and differences in the timing of the Fund’s valuation of: (i) the Underlying Fund and the currency forward contracts (each valued as of the close of the NYSE, typically 4:00 p.m., Eastern Time), (ii) the valuation of the securities in the Underlying Index (generally valued as of each security’s local market close) and (iii) the currency forward contracts included in the Underlying Index (generally valued at 4:00 p.m., London time).

U.S. Economic Risk. The U.S. is a significant, and in some cases the most significant, trading partner of, or foreign investor in, certain country or countries in which the Fund or the Underlying Fund invests. As a result, economic conditions of such countries may be particularly affected by changes in the U.S. economy. A decrease in U.S. imports, new trade and financial regulations, changes in the U.S. dollar exchange rate or an economic slowdown in the U.S. may have a material adverse effect on the economic conditions of such countries and, as a result, securities to which the Fund or the Underlying Fund has exposure.

value methodology as a result of trade suspensions or for other reasons. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities or other instruments in the Fund’s or the Underlying Fund's portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund's or the Underlying Fund's NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using prevailing market rates on the date of valuation as quoted by one or more data service providers. This conversion may result in a difference between the prices used to calculate the Fund's or the Underlying Fund's NAV and the prices used by the underlying index, which, in turn, could result in a difference between the Fund's performance and the performance of the underlying index. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies either directly or indirectly through the Fund's investments in the Underlying Fund.

maintain and, potentially, their size. The extent to which the Fund may invest in a company that engages in securities-related activities or banking is limited by applicable law. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financials sector, including effects not intended by such regulation. Recently enacted legislation in the U.S. has relaxed capital requirements and other regulatory burdens on certain U.S. banks. While the effect of the legislation may benefit certain companies in the financials sector, increased risk taking by affected banks may also result in greater overall risk in the financials sector. The impact of changes in capital requirements, or recent or future regulation in various countries, on any individual financial company or on the financials sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financials sector more severely than those of investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financials sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Insurance companies, in particular, may be subject to severe price competition and/or rate regulation, which may have an adverse impact on their profitability. The financials sector is particularly sensitive to fluctuations in interest rates. The financials sector is also a target for cyber attacks, and may experience technology malfunctions and disruptions. In recent years, cyber attacks and technology malfunctions and failures have become increasingly frequent in this sector and have reportedly caused losses to companies in this sector, which may negatively impact the Fund.

Information Technology Sector Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse

effect on their profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Portfolio Holdings Information

A Further Discussion of Principal Investment Strategies

Overview

The Fund allocates and reallocates its assets among direct investments in securities and other instruments, and in investments in the Underlying Fund consistent with the allocation and reallocation of securities in the Underlying Index as determined by the Index Provider. The Fund invests in currency forward contracts designed to hedge non-U.S. currency fluctuations inherent in the securities in the Underlying Index.

The Underlying Fund

The Fund invests a substantial portion of its assets in the Underlying Fund, so the Fund’s investment performance is likely to be directly related to the performance of the Underlying Fund. The Fund’s NAV will change with changes in the value of the Underlying Fund and other instruments in which the Fund invests, subject to the impact of currency hedges, which may cause the Fund to outperform or underperform the return of the Underlying Fund. An investment in the Fund will entail more direct and indirect costs and expenses than a direct investment in the Underlying Fund . The Underlying Fund invests in non-U.S. securities without implementing a hedge of the local currency risk. The currency hedging strategy employed by the Fund is subject to additional risks, as described in this Prospectus and in the Fund’s SAI.

BFA is not required to invest the Fund’s assets in any particular underlying fund, including the Underlying Fund, or allocate any particular percentage of the Fund’s assets to any particular underlying fund, including the Underlying Fund. Currently, the Fund seeks to achieve its investment objective by investing a substantial portion of its assets in the Underlying Fund.

The Underlying Fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the JPX-Nikkei Index 400. The JPX-Nikkei Index 400 is a servicemark of the Index Provider and has been licensed for use for certain purposes by BFA or its affiliates. The Underlying Fund is not sponsored, endorsed, sold, or promoted by the Index Provider and the Index Provider makes no representation regarding the advisability of investing in the Underlying Fund or the Fund.

In managing the Underlying Fund, BFA uses a representative sampling index strategy. Representative sampling is an indexing strategy that involves investing in a representative sample of securities that collectively have an investment profile similar to a specified benchmark index. Securities selected for the Underlying Fund are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the applicable underlying index. The Underlying Fund may or may not hold all of the securities that are included in its underlying index and may hold certain securities or other instruments that are not included in its underlying index or in the Underlying Index.

Management

For its investment advisory services to the Fund, BFA will be paid a management fee from the Fund based on a percentage of the Fund's average daily net assets, at the annual rate of 0.59%. In addition, BFA has contractually agreed to waive a portion of its management fees so that the Fund's total annual fund operating expenses after fee waiver is equal to the Acquired Fund Fees and Expenses attributable to the Fund's investment in JPXN, after taking into account any fee waivers by JPXN through July 31, 2020. The contractual waiver may be terminated prior to July 31, 2020 only upon written agreement of the Trust and BFA. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding Acquired Fund Fees and Expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Portfolio Managers. Diane Hsiung, Jennifer Hsui, Alan Mason, Orlando Montalvo and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

instruments as the Fund, including securities issued by other open-end and closed-end investment companies (which may include investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”)). The trading activities of BFA and these Affiliates are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA or an Affiliate having positions in certain securities that are senior or junior to, or having interests different from or adverse to, the securities that are owned by the Fund.

The Fund's activities may be limited because of regulatory restrictions applicable to one or more Affiliates and/or their internal policies designed to comply with such restrictions.

Shareholder Information

redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Although the SEC has granted an exemptive order to the Trust permitting registered investment companies and unit investment trusts that enter into a participation agreement with the Trust (“Investing Funds”) to invest in iShares funds beyond the limits set forth in Section 12(d)(1) of the 1940 Act subject to certain terms and conditions, the exemptive order is not applicable to the Fund. Accordingly, Investing Funds must adhere to the limits set forth in Section 12(d)(1) of the 1940 Act when investing in the Fund.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as the supply of and demand for ETF shares and shares of underlying securities held by the Fund, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout each trading day by the national securities exchange on which the Fund's shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities or other assets and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities or other assets or other instruments held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund's NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and price quotations obtained from broker-dealers and other market intermediaries that may trade in the portfolio securities or other assets held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the U.S. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the NYSE (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets, which includes the values of the Underlying Fund shares in which the Fund invests, less total

liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

The Fund, the Underlying Fund or both invest in non-U.S. securities. Foreign currency exchange rates with respect to the portfolio securities denominated in non-U.S. currencies are generally determined as of 4:00 p.m., London time. The Fund will also invest in currency forward contracts, which are generally valued as of 4:00 p.m., Eastern time. Non-U.S. securities held by the Fund, the Underlying Fund or both may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants (as defined in the Creations and Redemptions section of this Prospectus) will not be able to purchase or redeem Fund shares.

using fair value pricing will result in prices that may differ from current market valuations and that may not be the prices at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

Dividends and Distributions

gains, if any, in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates. Long-term capital gains and qualified dividend income are generally eligible for taxation at a maximum rate of 15% or 20% for non-corporate shareholders, depending on whether their income exceeds certain threshold amounts. In addition, a 3.8% U.S. federal Medicare contribution tax is imposed on “net investment income,” including, but not limited to, interest, dividends, and net gain, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly) and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substituted dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the U.S., which includes an exchange of information program, or if the stock with respect to which the dividend was paid is readily tradable on an established U.S. securities market. The term excludes a corporation that is a passive foreign investment company. Under current IRS guidance, the U.S. has a comprehensive income tax treaty with Japan.

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

Short term capital gains earned by the Underlying Fund will be ordinary income when distributed to the Fund and will not be offset by the Fund's capital losses. Because the Fund is expected to invest in the Underlying Fund, the Fund's realized losses on sales of shares of the Underlying Fund may be indefinitely or permanently deferred as “wash sales.” Capital loss carryforwards of the Underlying Fund, if any, would not offset net capital gains of the Fund.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a

return of capital to shareholders. Distributions in excess of the Fund’s minimum distribution requirements, but not in excess of the Fund’s earnings and profits, will be taxable to shareholders and will not constitute nontaxable returns of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder's cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

Dividends, interest and capital gains earned by the Underlying Fund with respect to securities issued by non-U.S. issuers may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the U.S. may reduce or eliminate such taxes. If more than 50% of the total assets of the Underlying Fund at the close of a year consists of non-U.S. stocks or securities (generally, for this purpose, depositary receipts, no matter where traded, of non-U.S. companies are treated as “non-U.S.”) (and 50% of the total assets of the Fund at the close of the year consists of securities issued by non-U.S. issuers, or, at the close of each quarter, shares of the Underlying Fund), the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund or the Underlying Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information concerning their account holders, or (ii) in the event that an applicable intergovernmental agreement and implementing legislation are adopted, provide local revenue authorities with similar account holder information. Other foreign entities may need to report the name, address, and taxpayer identification number of each substantial U.S. owner or provide certifications of no substantial U.S. ownership unless certain exceptions apply.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities (including any portion of such securities and other portfolio holdings for which cash may be substituted) held by the Fund and a specified amount of cash. Redeeming holders will receive cash in respect to the pro rata value of the currency forward contract and NDFs held by the Fund to the extent attributable to the Creation Unit being redeemed. Except when aggregated in Creation Units, shares are not redeemable by the Fund.

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended March 31, 2018.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price generally is determined by using the midpoint between the highest bid and the lowest ask on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund's NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund's inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

Performance as of March 31, 2018

	Average Annual Total Returns			Cumulative Total Returns
	NAV	MARKET	INDEX	NAV	MARKET	INDEX
1 Year	16.08%	16.01%	15.21%	16.08%	16.01%	15.21%
Since Inception*	10.63%	10.70%	11.14%	28.81%	29.03%	30.25%

*	Total returns for the period since inception are calculated from the inception date of the Fund (9/29/15). The first day of secondary market trading in shares of the Fund was 10/1/15.

iSHARES^® EMERGING MARKETS INFRASTRUCTURE ETF

Ticker: EMIF

Stock Exchange: NASDAQ

Investment Objective

The iShares Emerging Markets Infrastructure ETF (the “Fund”) seeks to track the investment results of an index composed of 30 of the largest emerging market equities in the infrastructure industry.

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except the management fees, interest expenses, taxes, expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, distribution fees or expenses, litigation expenses and any extraordinary expenses. The Fund may incur “Acquired Fund Fees and Expenses.” Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred by investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund's prospectus (the “Prospectus”). BFA, the investment adviser to the Fund, has contractually agreed to waive its management fees in an amount equal to the Acquired Fund Fees and Expenses, if any, attributable to investments by the Fund in other series of the Trust and iShares, Inc. through July 31, 2022. The contractual waiver may be terminated prior to July 31, 2022 only upon written agreement of the Trust and BFA.

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P Emerging Markets Infrastructure Index^TM (the “Underlying Index”), which is designed to track the performance of 30 of the largest publicly listed companies in the infrastructure industry in emerging markets, as determined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). The Underlying Index includes three distinct infrastructure sub-sectors: energy, transportation and utilities. As of March 31, 2018, the Underlying Index was comprised of stocks of companies in the following countries or regions: Brazil, Chilé,

China, Malaysia, Mexico, Russia (Russian Federation), South Korea and Thailand. Based on the current methodology, constituents must meet a minimum market capitalization threshold to be eligible for inclusion into the Underlying Index. The minimum total market capitalization as of the rebalancing reference date must be $250 million and the minimum float adjusted market capitalization as of the rebalancing reference date must be $200 million. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the energy, industrials, infrastructure and utilities industries or sectors. The components of the Underlying Index are likely to change over time.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active

S-2

management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

S-3

Energy Sector Risk. The market value of securities in the energy sector may decline for many reasons, including, among others, changes in energy prices, energy supply and demand, government

S-4

regulations and energy conservation efforts.

Industrials Sector Risk. Companies in the industrials sector may be adversely affected by changes in the supply of and

demand for products and services, product obsolescence, claims for environmental damage or product liability and changes in general economic conditions, among other factors.

Infrastructure Industry Risk. Companies in the infrastructure industry may be subject to a variety of factors that could adversely affect their business or operations, including high interest costs in connection with capital construction programs, high degrees of leverage, costs associated with governmental, environmental and other regulations, the level of government spending on infrastructure projects, and other factors. The stock prices of transportation companies may be affected by supply and demand for their specific product, government regulation, world events and economic conditions. The profitability of energy companies is related to worldwide energy prices, exploration, and production spending. Utilities companies face intense competition, which may have an adverse effect on their profit margins, and the rates charged by regulated utility companies are subject to review and limitation by governmental regulatory commissions.

S-5

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting issuers of non-U.S. securities or non-U.S. markets. In addition, non-U.S. securities markets may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times. The Fund is specifically exposed to Asian Economic Risk and Central and South American Economic Risk.

S-6

inadequate to address significant operational risks.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Reliance on Trading Partners Risk. The Fund invests in countries or regions whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund's investments. Through its portfolio companies' trading partners, the Fund is specifically exposed to U.S. Economic Risk.

Risk of Investing in China. Investments in Chinese securities, including certain Hong Kong-listed securities, subject the Fund to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is an emerging market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the last few decades, the Chinese government has undertaken reform of economic and market practices and has expanded the sphere of private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Internal social unrest or

confrontations with other neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher rates of inflation. China has experienced security concerns, such as terrorism and strained international relations. Incidents involving China's or the region's security may cause uncertainty in Chinese markets and may adversely affect the Chinese economy and the Fund's investments. Export growth continues to be a major driver of China's rapid economic growth. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers, or a downturn in any of the economies of China's key trading partners may have an adverse impact on the Chinese economy.

the settlement of portfolio transactions and loss of the Fund’s ownership rights in its portfolio securities as a result of the system of share registration and custody in Russia. A number of jurisdictions, including the U.S., Canada and the European Union (the “EU”), have imposed economic sanctions on certain Russian individuals and Russian corporate entities. These and future sanctions, or even the threat of further sanctions, may adversely affect Russia’s economy and the Fund’s investments.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns, such as terrorism and strained international relations. Incidents involving a country's or region's security may cause uncertainty in its markets and may adversely affect its economy and the Fund's investments.

negatively impacted. In addition, any resulting liquidation of the Fund could cause the Fund to incur elevated transaction costs for the Fund and negative tax consequences for its shareholders.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

S-8

Utilities Sector Risk. The utilities sector is subject to significant government regulation and oversight. Deregulation, however, may subject utility companies to greater competition and may reduce their profitability. Companies in the utilities sector may be adversely affected due to increases in fuel and operating costs, rising costs of financing capital construction and the cost of complying with regulations, among other factors.

are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund's portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund's shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

More Information About the Fund

substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

things, inflation, interest rates, productivity, global demand for local products or resources, and regulation and governmental controls. This may cause the Fund to underperform other investment vehicles that invest in different asset classes.

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Central and South American Economic Risk. The economies of certain Central and South American countries have experienced high interest rates, economic volatility, inflation, currency devaluations, government defaults and high unemployment rates. In addition, commodities (such as oil, gas and minerals) represent a significant percentage of exports for the regions and many economies in these regions are particularly sensitive to fluctuations in commodity prices. Adverse economic events in one country may have a significant adverse effect on other countries of these regions.

of their local markets. In general, the less developed a country’s securities markets are, the greater the likelihood of custody problems.

this sector may be subject to substantial government regulation and contractual fixed pricing, which may increase the cost of doing business and limit the earnings of these companies. A significant portion of the revenues of these companies may depend on a relatively small number of customers, including governmental entities and utilities. As a result, governmental budget constraints may have a material adverse effect on the stock prices of companies in this sector. Energy companies may also operate in, or engage in, transactions involving countries with less developed regulatory regimes or a history of expropriation, nationalization or other adverse policies. Energy companies also face a significant risk of liability from accidents resulting in injury or loss of life or property, pollution or other environmental problems, equipment malfunctions or mishandling of materials and a risk of loss from terrorism, political strife or natural disasters. Any such event could have serious consequences for the general population of the affected area and could have an adverse impact on the Fund’s portfolio and the performance of the Fund. Energy companies can be significantly affected by the supply of, and demand for, specific products (e.g., oil and natural gas) and services, exploration and production spending, government subsidization, world events and general economic conditions. Energy companies may have relatively high levels of debt and may be more likely than other companies to restructure their businesses if there are downturns in energy markets or in the global economy.

any agent’s errors. Errors in respect of the quality, accuracy and completeness of the data used to compile the Underlying Index may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, particularly where the indices are less commonly used as benchmarks by funds or managers. Therefore, gains, losses or costs associated with errors of the Index Provider or its agents will generally be borne by the Fund and its shareholders. For example, during a period where the Underlying Index contains incorrect constituents, the Fund would have market exposure to such constituents and would be underexposed to the Underlying Index’s other constituents. Such errors may negatively or positively impact the Fund and its shareholders.

Infrastructure Industry Risk. Companies in the infrastructure industry may be subject to a variety of factors that could adversely affect their business or operations, including high interest costs in connection with capital construction programs, high degrees of leverage, costs associated with governmental, environmental and other regulations, the effects of economic slowdowns, increased competition from other providers of services, uncertainties concerning costs, the level of government spending on infrastructure projects, and other factors. Infrastructure companies may be adversely affected by commodity price volatility, changes in exchange rates, import controls, depletion of resources, technological developments, and labor relations. There is also the risk that corruption may negatively affect publicly funded

infrastructure projects, especially in emerging markets, resulting in delays and cost overruns. Infrastructure issuers can be significantly affected by government spending policies because companies involved in this industry rely to a significant extent on U.S. and other government demand for their products.

Infrastructure companies in the oil and gas industry may be adversely affected by government regulation or world events in the regions that the companies operate (e.g., expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and repatriation of capital, military coups, social unrest, violence or labor unrest). Infrastructure companies may have significant capital investments in, or engage in transactions involving, emerging market countries, which may heighten these risks.

Operations Risk. The failure of an infrastructure company to carry adequate insurance or to operate its assets appropriately could lead to significant losses. Infrastructure may be adversely affected by environmental clean-up costs and catastrophic events such as earthquakes, hurricanes and terrorist acts.

Customer Risk. Infrastructure companies can be dependent upon a narrow customer base. Additionally, if these customers fail to pay their obligations, significant revenues could be lost and may not be replaceable.

Regulatory Risk. Infrastructure companies may be subject to significant regulation by various governmental authorities and also may be affected by regulation of rates charged to customers, service interruption due to environmental, operational or other events, the imposition of special tariffs and changes in tax laws, regulatory policies and accounting standards.

Strategic Asset Risk. Infrastructure companies may control significant strategic assets (e.g., major pipelines or highways), which are assets that have a national or regional profile, and may have monopolistic characteristics. Given their national or regional profile or irreplaceable nature, strategic assets could generate additional risk not common in other industry sectors and they may be targeted for terrorist acts or adverse political actions.

Interest Rate Risk. Rising interest rates could result in higher costs of capital for infrastructure companies, which could negatively impact their ability to meet payment obligations.

Leverage Risk. Infrastructure companies can be highly leveraged which increases investments risk and other risks normally associated with debt financing, and could adversely affect an infrastructure company's operations and market value in periods of rising interest rates.

Inflation Risk. Many infrastructure companies may have fixed income streams. Consequently, their market values may decline in times of higher inflation. Additionally, the prices that an infrastructure company is able to charge users of its assets may be linked to inflation, whether by government regulation, contractual arrangement or other factors. In this case, changes in the rate of inflation may affect the company's profitability.

Oil and Gas Risk. The profitability of oil and gas companies is related to worldwide energy prices, exploration, and production spending.

Market Trading Risk

to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

commission and other charges. In addition, you may incur the cost of the “spread”; that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). The spread, which varies over time for shares of the Fund based on trading volume and market liquidity, is generally narrower if the Fund has more trading volume and market liquidity and wider if the Fund has less trading volume and market liquidity. In addition, increased market volatility may cause wider spreads. There may also be regulatory and other charges that are incurred as a result of trading activity. Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments through a brokerage account.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

■	Lower levels of liquidity and market efficiency;
■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;

■	Limitations on foreign ownership of securities;
■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements; and

■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the U.S.

Reliance on Trading Partners Risk. The economies of many countries in which the Fund invests are highly dependent on trade with certain key trading partners. Reduction in spending on products and services by these key trading partners, institution of tariffs or other trade barriers or a slowdown in the economies of key trading partners may adversely affect the performance of any company in which the Fund invests and have a material adverse effect on the Fund’s performance.

on foreign investments and on repatriation of capital invested.

in emerging market countries than developed countries. Moreover, emerging markets often have less uniformity in accounting and reporting requirements, less reliable securities valuations and greater risks associated with custody of securities than developed markets. In addition, emerging markets often have greater risk of capital controls through such measures as taxes or interest rate control than developed markets. Certain emerging market countries may also lack the infrastructure necessary to attract large amounts of foreign trade and investment.

Risk of Investing in Russia. Investing in Russian securities involves significant risks, in addition to those described under “Risk of Investing in Emerging Markets” and “Non-U.S. Securities Risk” that are not typically associated with investing in U.S. securities, including:

■	The risk of delays in settling portfolio transactions and the risk of loss arising out of the system of share registration and custody used in Russia;
■	Risks in connection with the maintenance of the Fund’s portfolio securities and cash with foreign sub-custodians and securities depositories, including the risk that appropriate sub-custody arrangements will not be available to the Fund;
■	The risk that the Fund’s ownership rights in portfolio securities could be lost through fraud or negligence because ownership in shares of Russian companies is recorded by the companies themselves and by registrars, rather than by a central registration system; and
■	The risk that the Fund may not be able to pursue claims on behalf of its shareholders because of the system of share registration and custody, and because Russian banking institutions and registrars are not guaranteed by the Russian government.

Russia Sanctions. The U.S. and the Economic and Monetary Union of the EU, along with the regulatory bodies of a number of countries including Japan, Australia, Norway, Switzerland and Canada (collectively, “Sanctioning Bodies”), have imposed economic sanctions, which can consist of prohibiting certain securities trades, prohibiting certain private transactions in the energy sector, asset freezes and prohibition of all business, against certain Russian individuals and Russian corporate entities. The Sanctioning Bodies could also institute broader sanctions on Russia. These sanctions, or even the threat of further sanctions, may result in the decline of the value and liquidity of Russian securities, a weakening of the ruble or other adverse consequences to the Russian economy. These sanctions could also result in the immediate freeze of Russian securities and/or funds invested in prohibited assets, impairing the ability of the Fund to buy, sell, receive or deliver those securities and/or assets. Additional sanctions against Russia have been, and may in the future be, imposed by the U.S. or other countries.

The sanctions against certain Russian issuers include prohibitions on transacting in or dealing in issuances of debt or equity of such issuers. Compliance with each of these sanctions may impair the ability of the Fund to buy, sell, hold, receive or deliver the affected securities or other securities of such issuers. If it becomes impracticable or unlawful for the Fund to hold securities subject to, or otherwise affected by, sanctions (collectively, “affected securities”), or if deemed appropriate by BFA, the Fund may prohibit in-kind deposits of the affected securities in connection with creation

transactions and instead require a cash deposit, which may also increase the Fund's transaction costs. The Fund may also be legally required to freeze assets in a blocked account.

Also, if an affected security is included in the Fund’s Underlying Index, the Fund may, where practicable, seek to eliminate its holdings of the affected security by employing or augmenting its representative sampling strategy to seek to track the investment results of its Underlying Index. The use of (or increased use of) a representative sampling strategy may increase the Fund’s tracking error risk. If the affected securities constitute a significant percentage of the Underlying Index, the Fund may not be able to effectively implement a representative sampling strategy, which may result in significant tracking error between the Fund’s performance and the performance of its Underlying Index.

Current or future sanctions may result in Russia taking counter measures or retaliatory actions, which may further impair the value and liquidity of Russian securities. These retaliatory measures may include the immediate freeze of Russian assets held by the Fund. In the event of such a freeze of any Fund assets, including depositary receipts, the Fund may need to liquidate non-restricted assets in order to satisfy any Fund redemption orders. The liquidation of Fund assets during this time may also result in the Fund receiving substantially lower prices for its securities.

These sanctions may also lead to changes in the Fund’s Underlying Index. The Fund’s Index Provider may remove securities from the Underlying Index or implement caps on the securities of certain issuers that have been subject to recent economic sanctions. In such an event, it is expected that the Fund will rebalance its portfolio to bring it in line with the Underlying Index as a result of any such changes, which may result in transaction costs and increased tracking error. These sanctions, the volatility that may result in the trading markets for Russian securities and the possibility that Russia may impose investment or currency controls on investors may cause the Fund to invest in, or increase the Fund’s investments in, depositary receipts that represent the securities of the Underlying Index. These investments may result in increased transaction costs and increased tracking error.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism and strained international relations due to territorial disputes, historical animosities, defense concerns and other security concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect their economies.

Structural Risk. Certain countries in which the Fund invests may experience currency devaluations, substantial rates of inflation or economic recessions, causing a negative effect on their economies and securities markets.

U.S. Economic Risk. The U.S. is a significant, and in some cases the most significant, trading partner of, or foreign investor in, certain country or countries in which the Fund invests. As a result, economic conditions of such countries may be particularly affected by changes in the U.S. economy. A decrease in U.S. imports, new trade and financial regulations, changes in the U.S. dollar exchange rate or an economic slowdown in the U.S. may have a material adverse effect on the economic conditions of such countries and, as a result, securities to which the Fund has exposure.

man-made or natural disasters. Existing and future regulations or legislation may make it difficult for utility companies to operate profitably. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. In certain countries, regulatory authorities may also restrict utility companies’ access to new markets, thereby diminishing these companies’ long-term prospects. There is no assurance that regulatory authorities will grant rate increases in the future or that such increases will be adequate to permit the payment of dividends on stocks issued by a utility company. Energy conservation and changes in climate policy may also have a significant adverse impact on the revenues and expenses of utility companies.

Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund's valuation of the security or other asset and from the value used by the Underlying Index, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund's NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using prevailing market rates on the date of valuation as quoted by one or more data service providers. This conversion may result in a difference between the prices used to calculate the Fund's NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund's performance and the performance of the Underlying Index. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Management

litigation expenses and any extraordinary expenses (as determined by a majority of the Trustees who are not “interested persons” of the Trust).

For its investment advisory services to the Fund, BFA is paid a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.75%. BFA has contractually agreed to waive its management fees in an amount equal to the Acquired Fund Fees and Expenses attributable, if any, to investments by the Fund in other series of the Trust and iShares, Inc. through July 31, 2022. The contractual waiver may be terminated prior to July 31, 2022 only upon written agreement of the Trust and BFA. In addition, BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding Acquired Fund Fees and Expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Alan Mason has been employed by BFA as a portfolio manager since 1991. Mr. Mason has been a Portfolio Manager of the Fund since 2016.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

BFA or an Affiliate may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and

which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

Dividends and Distributions

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

Dividends, interest and capital gains earned by the Fund with respect to securities issued by non-U.S. issuers may give rise to withholding, capital gains and other taxes

imposed by non-U.S. countries. Tax conventions between certain countries and the U.S. may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities (generally, for this purpose, depositary receipts, no matter where traded, of non-U.S. companies are treated as “non-U.S.”), generally the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

foreign tax credits passed through by the Fund if your Fund shares are loaned out pursuant to a securities lending agreement.

Chinese Tax Disclosure. The Fund’s investments in securities issued by PRC companies may cause the Fund to become subject to withholding and other taxes imposed by the PRC. If the Fund were considered to be a tax resident of the PRC, it would be subject to PRC corporate income tax at the rate of 25% on its worldwide taxable income. If the Fund were considered to be a non-resident enterprise with a “permanent establishment” in the PRC, it would be subject to PRC corporate income tax of 25% on the profits attributable to the permanent establishment. BFA intends to operate the Fund in a manner that will prevent it from being treated as a tax resident of the PRC and from having a permanent establishment in the PRC. It is possible, however, that the PRC could disagree with that conclusion or that changes in PRC tax law could affect the PRC corporate income tax status of the Fund. The PRC generally imposes withholding income tax at a rate of 10% on dividends, premiums, interest and capital gains originating in the PRC and paid to a company that is not a resident of the PRC for tax purposes and that has no permanent establishment in China. The withholding is in general made by the relevant PRC tax resident company making such payments. In the event the relevant PRC tax resident company fails to withhold the relevant PRC withholding income tax or otherwise fails to pay the relevant withholding income tax to the PRC tax authorities, the competent PRC tax authorities may, at their sole discretion, impose tax obligations on the Fund. Foreign investors will be temporarily exempt from withholding income tax on capital gains derived from the trading of certain shares starting on November 17, 2014. The exemptions are temporary and there is no indication how long the exemptions will continue. While the application and enforcement of this law to the Fund remains subject to clarification, to the extent that such taxes are imposed on any capital gains of the Fund, the Fund's NAV or returns may be adversely impacted. Stamp duty under the PRC laws generally applies to the execution and receipt of taxable documents, which include contracts for

the sale of shares traded on PRC stock exchanges. In the case of such contracts, the stamp duty is currently imposed on the seller but not on the purchaser, at the rate of 0.1%.

To the extent the Fund engages in in-kind transactions, the Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying

redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined in Rule 144A under the 1933 Act, will not be able to receive restricted securities eligible for resale under Rule 144A.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer, processing and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation and redemption transaction fees are charged on each Creation Unit created or redeemed, as applicable, by an Authorized Participant on the day of the transaction. The standard transaction fee is generally fixed at the amount shown in the table regardless of the number of Creation Units being purchased or redeemed, but may be reduced by the Fund if transfer and processing expenses associated with the creation or redemption are anticipated to be lower than the stated fee. If a purchase or redemption consists solely or partially of cash, the Authorized Participant may also be required to pay an additional transaction charge (up to the maximum amounts shown in the table below) to cover brokerage and certain other costs related to a creation or redemption transaction. Investors who use the services of a broker or other financial intermediary to acquire or dispose of Fund shares may pay fees for such services.

Approximate Value of a Creation Unit		Creation Unit Size		Standard Creation/ Redemption Transaction Fee		Maximum Additional Charge for Creations*		Maximum Additional Charge for Redemptions*
$1,584,500		50,000		$250		7.0%		2.0%

*	As a percentage of the net asset value per Creation Unit, inclusive, in the case of redemptions, of the standard redemption transaction fee.

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P Europe 350^TM (the “Underlying Index”), which measures the performance of the stocks of leading companies in the following countries: Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom (the “U.K.”). The market capitalization of constituent companies is adjusted to reflect the available float and, if necessary, any foreign investment restrictions. The stocks in the Underlying Index are chosen by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”) for market size, liquidity, industry group representation and geographic diversity. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the financials industry or sector. The components of the Underlying Index are likely to change over time.

by BFA or its affiliates, as well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

S-3

S-4

a period of time or at all, which may have an adverse impact on the Fund and its shareholders.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

S-5

inadequate to address significant operational risks.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Risk of Investing in Developed Countries. The Fund’s investment in developed country issuers may subject the Fund to regulatory, political, currency, security, economic and other risks associated with developed countries. Developed countries tend to represent a significant portion of the global economy and have generally experienced slower economic growth than some less developed countries. Certain developed countries have experienced security concerns, such as terrorism and strained international relations. Incidents involving a country’s or region’s security may cause uncertainty in its markets and may adversely affect its economy and the Fund’s investments. In addition, developed countries may be adversely impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, debt burdens and the price or availability of certain commodities.

Risk of Investing in Europe. The Fund is more exposed to the economic and political risks of Europe and of the European countries in which it invests than funds whose investments are more geographically diversified. Adverse economic and political events in Europe may cause the Fund’s investments to decline in value. The economies and markets of European countries are often closely connected and interdependent, and events in one country in Europe can have an adverse impact on other

European countries. The Fund makes investments in securities of issuers that are domiciled in, or have significant operations in, member states of the European Union (the “EU”) that are subject to economic and monetary controls that can adversely affect the Fund’s investments. The European financial markets have experienced volatility and adverse trends in recent years and these events have adversely affected the exchange rate of the euro and may continue to significantly affect other European countries.

Risk of Investing in the United Kingdom. Investments in U.K. issuers may subject the Fund to regulatory, political, currency, security, and economic risks specific to the U.K. The U.K. has one of the largest economies in Europe, and the U.S. and other European countries are substantial trading partners of the U.K. As a result, the U.K.’s economy may be impacted by changes to the economic condition of the U.S. and other European countries. Secessionist movements, such as the Catalan movement in Spain or Scotland, may have an adverse effect on the U.K. economy. In a referendum held on June 23, 2016, the U.K. resolved to leave the EU. The referendum may introduce significant uncertainties and instability in the financial markets as the U.K. negotiates its exit from the EU.

S-6

These events could also trigger adverse tax consequences for the Fund.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

business continuity plans in the event of, and risk management systems to prevent, such cyber attacks, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified and that prevention and remediation efforts will not be successful. Furthermore, the Fund cannot control the cyber security plans and systems put in place by service providers to the Fund, issuers in which the Fund invests, the Index Provider, market makers or Authorized Participants. The Fund and its shareholders could be negatively impacted as a result.

Geographic Risk. Some of the companies in which the Fund invests are located near the center of Europe's transportation network, which makes them vulnerable to environmental events (such as pollution, oil spills, etc.) that may have an adverse

impact on these economies. Some of the companies in which the Fund invests are located in parts of the world that have historically been prone to natural disasters such as droughts, earthquakes, flooding or volcanic eruptions, and are economically sensitive to environmental events. Any such event may adversely impact the economies of these geographic areas or business operations of companies in these geographic areas, causing an adverse impact on the value of the Fund.

other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline. An issuer may also be subject to risks associated with the countries, states and regions in which the issuer resides, invests, sells products, or otherwise conducts operations.

Market Trading Risk

discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments through a brokerage account.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

■	Lower levels of liquidity and market efficiency;
■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;
■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements; and

■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the U.S.

investment merits. BFA generally does not attempt to invest the Fund's assets in defensive positions under any market conditions, including declining markets.

Risk of Investing in Developed Countries. Investment in developed country issuers may subject the Fund to regulatory, political, currency, security, economic and other risks associated with developed countries. Developed countries generally tend to rely on services sectors (e.g., the financial services sector) as the primary means of economic growth. A prolonged slowdown in one or more services sectors is likely to have a negative impact on economies of certain developed countries, although economies of individual developed countries can be impacted by slowdowns in other sectors. In the past, certain developed countries have been targets of terrorism, and some geographic areas in which the Fund invests have experienced strained international relations due to territorial disputes, historical animosities, defense concerns and other security concerns. These situations may cause uncertainty in the financial markets in these countries or geographic areas and may adversely affect the performance of the issuers to which the Fund has exposure. Heavy regulation of certain markets, including labor and product markets, may have an adverse effect on certain issuers. Such regulations may negatively affect economic growth or cause prolonged periods of recession. Many developed countries are heavily indebted and face rising healthcare and retirement expenses. In addition, price fluctuations of certain commodities and regulations impacting the import of commodities may negatively affect developed country economies.

Risk of Investing in Europe. The Fund is more exposed to the economic and political risks of Europe and of the European countries in which it invests than are funds whose investments are more geographically diversified. Adverse economic and political events in Europe may cause the Fund’s investments to decline in value. The economies and markets of European countries are often closely connected and interdependent, and events in one country in Europe can have an adverse impact on other European countries. The Fund makes investments in securities of issuers that are domiciled in, or have significant operations in, member states of the EU. The EU requires compliance by member states with restrictions on inflation rates, deficits, interest rates and debt levels, as well as fiscal and monetary controls, each of which may significantly affect every country in Europe, including those countries that are not members of the EU. Changes in imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro (the common currency of certain EU countries), the default or threat of default by an EU member state on its sovereign debt, including, without limitation, the pending threat of default by Greece, or an economic recession in an EU member state may have a significant adverse effect on the economies of EU member states and their trading partners. The European financial markets have experienced volatility and adverse trends in recent years due to concerns about economic downturns or rising government debt levels in several European countries, including, but not limited to, Austria, Belgium, Cyprus, France, Greece, Ireland, Italy, Portugal, Spain and Ukraine. These events have adversely affected the exchange rate of the euro and may continue to significantly affect other European countries. Responses to the financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest and may limit future growth and

economic recovery or have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. The impact of these actions, especially if they occur in a disorderly fashion, is not clear but could be significant and far-reaching. In a referendum held on June 23, 2016, the U.K. resolved to leave the EU. The referendum may introduce significant uncertainties and instability in the financial markets as the U.K. negotiates its exit from the EU. Although the precise timeframe for the U.K.’s withdrawal is uncertain, on March 29, 2017, the U.K. initiated the withdrawal process by sending a formal notice of the country’s intention to withdraw from the EU. An agreement has been reached between the U.K. and the EU to continue negotiations on the U.K.’s exit from the EU. The outcome of negotiations remain uncertain. The impact of these actions, especially if they occur in a disorderly fashion, is not clear but could be significant and far-reaching. These events could negatively affect the value and liquidity of the Fund’s investments. Secessionist movements, such as the Catalan movement in Spain or Scotland, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value of the Fund. The Fund’s investments could be negatively impacted by any economic or political instability in any European country.

Risk of Investing in the United Kingdom. Investment in U.K. issuers may subject the Fund to regulatory, political, currency, security, and economic risks specific to the U.K. The U.K.’s economy relies heavily on the export of financial services to the U.S. and other European countries. A prolonged slowdown in the financial services sector may have a negative impact on the U.K.’s economy. In the past, the U.K. has been a target of terrorism. Acts of terrorism in the U.K. or against U.K. interests may cause uncertainty in the U.K.’s financial markets and adversely affect the performance of the issuers to which the Fund has exposure. Secessionist movements, such as the Catalan movement in Spain or Scotland, may have an adverse effect on the U.K. economy. In a referendum held on June 23, 2016, the U.K. resolved to leave the EU. The referendum may introduce significant uncertainties and instability in the financial markets as the U.K. negotiates its exit from the EU.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism and strained international relations due to territorial disputes,

historical animosities, defense concerns and other security concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect their economies.

Large Government Debt Risk. Chronic structural public sector deficits in some countries in which the Fund may invest may adversely impact securities held by the Fund.

shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund's NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using prevailing market rates on the date of valuation as quoted by one or more data service providers. This conversion may result in a difference between the prices used to calculate the Fund's NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund's performance and the performance of the Underlying Index. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

concerning healthcare have been considered by the U.S. Congress in recent years. It is unclear what proposals will ultimately be enacted, if any, and what effect they may have on companies in the healthcare sector.

Shareholder Information

Buying or selling Fund shares on an exchange or other secondary market involves two types of costs that may apply to all securities transactions. When buying or selling

shares of the Fund through a broker, you may incur a brokerage commission and other charges. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread,” that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on the Fund’s trading volume and market liquidity, and is generally lower if the Fund has high trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity (which is often the case for funds that are newly launched or small in size). The Fund's spread may also be impacted by the liquidity of the underlying securities held by the Fund, particularly for newly launched or smaller funds or in instances of significant volatility of the underlying securities.

any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

the Fund’s NAV may change on days when Authorized Participants (as defined in the Creations and Redemptions section of this Prospectus) will not be able to purchase or redeem Fund shares.

Dividends and Distributions

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

To the extent the Fund engages in in-kind transactions, the Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying

good faith estimate of transaction costs). Investors who use the services of a broker or other financial intermediary to acquire or dispose of Fund shares may pay fees for such services.

iSHARES^® GLOBAL 100 ETF

Ticker: IOO

Stock Exchange: NYSE Arca

Investment Objective

The iShares Global 100 ETF (the “Fund”) seeks to track the investment results of an index composed of 100 large-capitalization global equities.

Fees and Expenses

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P Global 100^TM (the “Underlying Index”), which is designed to measure the performance of the stocks of 100 large-capitalization global companies. The stocks in the Underlying Index are expected to be highly liquid and represent some of the largest multinational businesses in the world. The Underlying Index is a subset of the S&P Global 1200^TM and contains 100 common stocks, screened for sector representation, liquidity and size. The market capitalization of constituent companies is adjusted to reflect the available float and, if necessary, any foreign investment restrictions. As of March 31, 2018, the Underlying Index was comprised of stocks of companies in the following countries: Australia, France, Germany, Japan, the Netherlands, South Korea, Spain, Switzerland, the United Kingdom (the “U.K.”) and the U.S. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the financials and information technology industries

or sectors. The components of the Underlying Index are likely to change over time.

S-2

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

principal risks noted below, any of which may adversely affect the Fund's net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

S-3

and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

S-4

Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over

longer periods during more prolonged market downturns.

S-5

This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund's portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund's shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

More Information About the Fund

substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Responses to financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest, may limit future growth and economic recovery or may have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. In a referendum held on June 23, 2016, the U.K. resolved to leave the EU. The referendum may introduce significant uncertainties and instability in the financial markets as the U.K. negotiates its exit from the EU. Although the precise timeframe for the U.K.’s withdrawal is uncertain, on March 29, 2017, the U.K. initiated the withdrawal process by sending a formal notice of the country’s intention to withdraw from the EU. An agreement has been reached between the U.K. and the EU to continue negotiations on the U.K.’s exit from the EU. The outcome of negotiations remain uncertain.

Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

issuer may also be subject to risks associated with the countries, states and regions in which the issuer resides, invests, sells products, or otherwise conducts operations.

Market Trading Risk

advisable for investors who anticipate regularly making small investments through a brokerage account.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

■	Lower levels of liquidity and market efficiency;
■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;
■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements; and

■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the U.S.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

new laws, regulations and litigation. Companies in the consumer staples sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

difficult to raise prices and, in fact, may result in price discounting. Many new products in the healthcare sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly, and such efforts ultimately may be unsuccessful. Companies in the healthcare sector may be thinly capitalized and may be susceptible to product obsolescence. In addition, a number of legislative proposals concerning healthcare have been considered by the U.S. Congress in recent years. It is unclear what proposals will ultimately be enacted, if any, and what effect they may have on companies in the healthcare sector.

Portfolio Holdings Information

Management

For its investment advisory services to the Fund, BFA is paid a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.40%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Alan Mason has been employed by BFA as a portfolio manager since 1991. Mr. Mason has been a Portfolio Manager of the Fund since 2016.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

The Fund's activities may be limited because of regulatory restrictions applicable to one or more Affiliates and/or their internal policies designed to comply with such restrictions.

Shareholder Information

U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Dividends and Distributions

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a

return of capital to shareholders. Distributions in excess of the Fund’s minimum distribution requirements, but not in excess of the Fund’s earnings and profits, will be taxable to shareholders and will not constitute nontaxable returns of capital. The Fund’s capital loss carryforwards, if any, carried from taxable years beginning before 2011 do not reduce current earnings and profits, even if such carryforwards offset current year realized gains. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder's cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information concerning their account holders, or (ii) in the event that an applicable intergovernmental agreement and implementing legislation are adopted, provide local revenue authorities with similar account holder information. Other foreign entities may need to report the name, address, and taxpayer identification number of each substantial U.S. owner or provide certifications of no substantial U.S. ownership unless certain exceptions apply.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

The following table shows, as of May 2, 2018, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above and in the Fund's SAI):

Approximate Value of a Creation Unit		Creation Unit Size		Standard Creation/ Redemption Transaction Fee		Maximum Additional Charge for Creations*		Maximum Additional Charge for Redemptions*
$2,300,500		50,000		$2,000		3.0%		2.0%

*	As a percentage of the net asset value per Creation Unit, inclusive, in the case of redemptions, of the standard redemption transaction fee.

iSHARES^® GLOBAL CLEAN ENERGY ETF

Ticker: ICLN

Stock Exchange: NASDAQ

Investment Objective

The iShares Global Clean Energy ETF (the “Fund”) seeks to track the investment results of an index composed of global equities in the clean energy sector.

Fees and Expenses

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

$48		$151		$263		$591

S-1

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P Global Clean Energy Index^TM (the “Underlying Index”), which is designed to track the performance of approximately 30 of what are expected to be the most liquid and tradable securities of global companies involved in clean energy related businesses. The Underlying Index includes clean energy production companies, and clean energy equipment and technology providers, and the Fund is concentrated in the clean energy industry. For these purposes, “clean energy” sources include biofuel and biomass, ethanol and fuel alcohol, geothermal energy, hydroelectricity, and solar and wind energy. As of March 31, 2018, the Underlying Index was comprised of stocks and companies in the following countries or regions: Brazil, Canada, Chilé, China, Denmark, Germany, Japan, New Zealand, Norway, Portugal, Spain, the United Kingdom (the “U.K.”) and the U.S. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying

Index is represented by securities of companies in the industrials, information technology and utilities industries or sectors. The components of the Underlying Index are likely to change over time.

The Fund generally will invest at least 90% of its assets in the component securities of the Underlying Index and in

S-2

investments that have economic characteristics that are substantially identical to the component securities of the Underlying Index (i.e., depositary receipts representing securities of the Underlying Index) and may invest up to 10% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, as well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

S-3

Clean Energy Sub-Industry Risk. Clean energy companies may be highly dependent upon government subsidies, contracts with government entities, and the successful development of new and proprietary technologies. In addition, seasonal weather conditions, fluctuations in the supply of and demand for clean energy products, changes in energy prices, and international political events may cause fluctuations in the performance of clean energy companies and the prices of their securities.

Cyber Security Risk. Failures or breaches of the electronic systems of the Fund, the Fund's adviser,

distributor, and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions and negatively impact the Fund’s business operations, potentially resulting in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cyber security plans and systems of the Fund’s service providers, the Index Provider, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Index-Related Risk. There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the Fund will achieve its

S-4

investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-

term market movements and over longer periods during more prolonged market downturns.

S-5

markets. In addition, non-U.S. securities markets may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times. The Fund is specifically exposed to Asian Economic Risk and European Economic Risk.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Asian Economic Risk, European Economic Risk and U.S. Economic Risk.

Risk of Investing in China. Investments in Chinese issuers subject the Fund to risks specific to China. Investments in certain Hong Kong-listed securities may also subject the Fund to exposure to Chinese companies. China may be subject to considerable degrees of economic, political and social instability. China is an emerging market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the last few decades, the Chinese government has undertaken reform of economic and market practices and has expanded the sphere of private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Internal social unrest or confrontations with other neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher rates of inflation. China has experienced security concerns, such as terrorism and strained international relations. Incidents involving China's or the region's security may cause uncertainty in Chinese markets and may adversely affect the Chinese economy and the Fund's investments. Export growth continues to be a major driver of China's rapid economic growth. Reduction in spending on Chinese products and services, institution of

S-6

tariffs or other trade barriers, or a downturn in any of the economies of China's key trading partners may have an adverse impact on the Chinese economy.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Tracking Error Risk. The Fund may be subject to tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur because of

S-7

differences between the securities and other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences (including, as applicable, differences between a security’s price at the local market close and the Fund's valuation of a security at the time of calculation of the Fund's NAV), differences in transaction costs, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or interest, tax gains or losses, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

Purchase and Sale of Fund Shares

The Fund is an ETF. Individual shares of the Fund are listed on a national securities exchange. Most investors will buy and sell shares of the Fund through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than at NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 100,000 shares or multiples thereof (“Creation Units”) to Authorized Participants who have entered into agreements with the Fund's distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

More Information About the Fund

substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Clean Energy Sub-Industry Risk. Many clean energy companies are involved in the development and commercialization of new technologies, which may be subject to delays resulting from budget constraints and technological difficulties. Clean energy companies may be highly dependent upon government subsidies and contracts with government entities, and may be negatively affected if such subsidies or contracts are unavailable. Clean energy companies may depend on the successful development of new and proprietary technologies. In addition, seasonal weather conditions, fluctuations in the supply of, and demand for, clean energy products, changes in energy prices, and international political events may cause fluctuations in the performance of clean energy companies and the prices of their securities.

make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that may not be subject to independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities markets are, the greater the likelihood of custody problems.

Underlying Index is comprised of common stocks, which generally subject their holders to more risks than holders of preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Responses to financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest, may limit future growth and economic recovery or may have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. In a referendum held on June 23, 2016, the U.K. resolved to leave the EU. The referendum may introduce significant uncertainties and instability in the financial markets as the U.K. negotiates its exit from the EU. Although the precise timeframe for the U.K.’s withdrawal is uncertain, on March 29, 2017, the U.K. initiated the withdrawal process by sending a formal notice of the country’s intention to withdraw from the EU. An agreement has been reached between the U.K. and the EU to continue negotiations on the U.K.’s exit from the EU. The outcome of negotiations remain uncertain.

Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

in this sector tend to rely to a significant extent on government demand for their products and services.

Market Trading Risk

can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund's shares may be less actively traded in certain markets than in others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

or its underlying investments, which may contribute to the Fund’s shares trading at a premium or discount to NAV.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

China than in many other countries of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher rates of inflation as a result of internal social unrest or conflicts with other countries. Unanticipated political or social developments may result in sudden and significant investment losses. China's growing income inequality, rapidly aging population and significant environmental issues also are factors that may affect the Chinese economy.

been marked by protests and violence. These situations may cause uncertainty in the Chinese market and may adversely affect the Chinese economy. In addition, conflict on the Korean Peninsula could adversely affect the Chinese economy.

The U.S. has developed increasingly strained relations with a number of foreign countries, including traditional allies, such as certain European countries, and historical adversaries, such as North Korea, Iran, China and Russia. If these relations were to worsen, it could adversely affect U.S. issuers as well as non-U.S. issuers that rely on the U.S. for trade. The U.S. has also experienced increased internal unrest and discord. If this trend were to continue, it may have an adverse impact on the U.S. economy and many of the issuers in which the Fund invests.

Utilities Sector Risk. Deregulation may subject utility companies to greater competition and may adversely affect their profitability. As deregulation allows utility companies to diversify outside of their original geographic regions and their traditional lines of business, utility companies may engage in riskier ventures. In addition, deregulation may eliminate restrictions on the profits of certain utility companies, but may also subject these companies to greater risk of loss. Companies in the utilities industry may have difficulty obtaining an adequate return on invested capital, raising capital, or financing large construction projects during periods of inflation or unsettled capital markets; face restrictions on operations and increased cost and delays attributable to environmental considerations and regulation; find that existing plants, equipment or products have been rendered obsolete by technological innovations; or be subject to increased costs because of the scarcity of certain fuels or the effects of man-made or natural disasters. Existing and future regulations or legislation may make it difficult for utility companies to operate profitably. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. In certain countries, regulatory authorities may also restrict utility companies’ access to new markets, thereby diminishing these companies’ long-term prospects. There is no

assurance that regulatory authorities will grant rate increases in the future or that such increases will be adequate to permit the payment of dividends on stocks issued by a utility company. Energy conservation and changes in climate policy may also have a significant adverse impact on the revenues and expenses of utility companies.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Australasian Economic Risk. The economies of Australasia, which include Australia and New Zealand, are dependent on exports from the energy, agricultural and mining sectors. This makes Australasian economies susceptible to fluctuations in the commodity markets. Australasian economies are also increasingly dependent on their growing service industries. Because the economies of Australasia are dependent on the economies of Asia, Europe and the U.S. as key trading partners and investors, reduction in spending by any of these trading partners on Australasian products and services, or negative changes in any of these economies, may cause an adverse impact on some or all of the Australasian economies.

Commercial and Professional Services Industry Risk. The success of commercial and professional service providers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, availability of qualified personnel and corporate demand. The commercial and professional services industry depends heavily on corporate spending. Companies in the commercial and professional services industry may be subject to severe competition, which may also have an adverse impact on their profitability.

equipment expenditures could be substantial, and equipment generally suffers from rapid obsolescence. Companies in the semiconductor industry are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights, would adversely affect the profitability of these companies.

shareholder's cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

Chinese Tax Disclosure. The Fund’s investments in securities, issued by People's Republic of China (the “PRC”) companies may cause the Fund to become subject to withholding and other taxes imposed by the PRC. If the Fund were considered to be a tax resident of the PRC, it would be subject to PRC corporate income tax at the rate of 25% on its worldwide taxable income. If the Fund were considered to be a non-resident enterprise with a “permanent establishment” in the PRC, it would be subject to PRC corporate income tax of 25% on the profits attributable to the permanent establishment. BFA intends to operate the Fund in a manner that will prevent it from being treated as a tax resident of the PRC and from having a permanent establishment in the PRC. It is possible, however, that the PRC could disagree with that conclusion or that changes in PRC tax law could affect the PRC corporate income tax status of the Fund. The PRC generally imposes withholding income tax at a rate of 10% on dividends, premiums, interest and capital gains originating in the PRC and paid to a company that is not a resident of the PRC for tax purposes and that has no permanent establishment in China. The withholding is in general made by the relevant PRC tax resident company making such payments. In the event the relevant PRC tax resident company fails to withhold the relevant PRC withholding income tax or otherwise fails to pay the relevant withholding income tax to the PRC tax authorities, the competent PRC tax authorities may, at their sole discretion, impose tax obligations on the Fund. Foreign investors will be temporarily exempt from withholding income tax on capital gains derived from the trading of certain shares starting on November 17, 2014. The exemptions are temporary and there is no indication how long the exemptions will continue. While the application and enforcement of this law to the Fund remains subject to clarification, to

the extent that such taxes are imposed on any capital gains of the Fund, the Fund's NAV or returns may be adversely impacted. Stamp duty under the PRC laws generally applies to the execution and receipt of taxable documents, which include contracts for the sale of shares traded on PRC stock exchanges. In the case of such contracts, the stamp duty is currently imposed on the seller but not on the purchaser, at the rate of 0.1%.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 100,000 shares or multiples thereof. Each “creator” or authorized participant (an “Authorized Participant”) has entered into an agreement with the Fund's distributor, BlackRock Investments, LLC (the “Distributor”), an affiliate of BFA.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P Global 1200 Consumer Discretionary Index^TM (the “Underlying Index”), which measures the performance of companies that S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”), a subsidiary of S&P Global, Inc., deems to be part of the consumer discretionary sector of the economy and that SPDJI believes are important to global markets. It is a subset of the S&P Global 1200^TM. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the consumer discretionary industry or sector. The components of the Underlying Index are likely to change over time. As of March 31, 2018, the Underlying Index was comprised of stocks of companies in the following countries or regions: Australia, Brazil, Canada, Chilé, China, Denmark, Finland, France, Germany, Hong Kong, Ireland, Italy, Japan, Luxembourg, Mexico, the Netherlands, South Korea, Spain,

Sweden, Switzerland, the United Kingdom (the “U.K.”) and the U.S.

S-2

cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, as well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

trading price, yield, total return and ability to meet its investment objective.

Automotive Sub-Industry Risk. The automotive sub-industry can be highly cyclical and companies in the automotive sub-industry may suffer periodic losses. Among other things, the automotive sub-industry is susceptible to labor disputes, economic downturns and increase in component and material prices. As a result, such risks, among

S-3

others, may adversely affect the value of the Fund’s investments.

As a result, the Fund's NAV may change quickly and without warning.

S-4

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Media and Entertainment Industries Risk. Several factors can significantly affect companies in the media and entertainment industries, including competition, particularly in formulation products and services using new technologies, cyclicality of revenues and earnings, a potential decrease in the discretionary income of targeted individuals, changing consumer tastes and interests, and the potential increase in state and federal government regulation. Companies in the media and entertainment industries may become obsolete quickly.

S-5

NAV that may be greater than those experienced by other ETFs.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Retail Sub-Industry Risk. The retail sub-industry may be affected by changes in domestic and international economies, consumer confidence, disposable household income and

spending, and consumer tastes and preferences. Companies in the retail sub-industry face intense competition.

S-6

investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

S-7

Performance Information

More Information About the Fund

substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Automotive Sub-Industry Risk. Investments in the automotive sub-industry involve risks that are specific to the automotive sub-industry, including economic downturns, changing consumer tastes, product obsolescence, and increases in component or material prices. The automotive sub-industry can be highly cyclical and may be significantly affected by labor disputes. As a result, such risks, among others, may adversely affect the value of the Fund’s investments.

Consumer Durables Industry Risk. The consumer durables industry includes companies involved in the design, production, or distribution of household durables, leisure equipment and goods, textiles, luxury goods or apparel, each of which may be affected by changes in domestic and international economies, consumer confidence, disposable household income and spending, and consumer tastes and preferences. Companies in the consumer durables industry face intense competition, which may have an adverse effect on their profitability. The success of companies in the consumer durables industry may be strongly affected by social trends and marketing campaigns. Companies in the consumer durables industry may be dependent on outside financing, which may be difficult to obtain. Many of these companies are dependent on third party suppliers and distribution systems. Consumer durables companies may be unable to protect their intellectual property rights or may be liable for infringing the intellectual property rights of others. In addition, goods in the consumer durables industry may face the risk of rapid obsolescence.

Responses to financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest, may limit future growth and economic recovery or may have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. In a referendum held on June 23, 2016, the U.K. resolved to leave the EU. The referendum may introduce significant uncertainties and instability in the financial markets as the U.K. negotiates its exit from the EU. Although the precise timeframe for the U.K.’s withdrawal is uncertain, on March 29, 2017, the U.K. initiated the withdrawal process by sending a formal notice of the country’s intention to withdraw from the EU. An agreement has been reached between the U.K. and the EU to continue negotiations on the U.K.’s exit from the EU. The outcome of negotiations remain uncertain.

Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

the Underlying Index will be determined, composed or calculated accurately. While the Index Provider provides descriptions of what the Underlying Index is designed to achieve, neither the Index Provider nor its agents provide any warranty or accept any liability in relation to the quality, accuracy or completeness of the Underlying Index or its related data, and they do not guarantee that the Underlying Index will be in line with the Index Provider’s methodology. BFA’s mandate as described in this Prospectus is to manage the Fund consistently with the Underlying Index provided by the Index Provider to BFA. BFA does not provide any warranty or guarantee against the Index Provider’s or any agent’s errors. Errors in respect of the quality, accuracy and completeness of the data used to compile the Underlying Index may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, particularly where the indices are less commonly used as benchmarks by funds or managers. Therefore, gains, losses or costs associated with errors of the Index Provider or its agents will generally be borne by the Fund and its shareholders. For example, during a period where the Underlying Index contains incorrect constituents, the Fund would have market exposure to such constituents and would be underexposed to the Underlying Index’s other constituents. Such errors may negatively or positively impact the Fund and its shareholders.

Market Trading Risk

motion pictures, music by recording artists, casinos, and recreation and amusement businesses) may become obsolete quickly. Advertising spending can be an important revenue source for media and entertainment companies. During economic downturns advertising spending typically decreases and, as a result, media and entertainment companies tend to generate less revenue.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

■	Lower levels of liquidity and market efficiency;
■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;
■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements; and

■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the U.S.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests

in securities included in, or representative of, the Underlying Index, regardless of their investment merits. BFA generally does not attempt to invest the Fund's assets in defensive positions under any market conditions, including declining markets.

Retail Sub-Industry Risk. The retail sub-industry may be affected by changes in domestic and international economies, interest rates, commodity prices, consumer confidence, disposable household income and spending, and consumer tastes and preferences. Companies in the retail sub-industry face intense competition, which may have an adverse effect on their profitability. The success of these companies may be strongly affected by social trends and marketing campaigns, and they may depend heavily on availability of credit, the overall health of the economy and the introduction of popular retail products. Companies in the retail sub-industry may be dependent on outside financing, which may be difficult to obtain. Many of these companies are dependent on third party suppliers and distribution systems. Retail companies may be unable to protect their intellectual property rights or may be liable for infringing upon the intellectual property rights of others.

Russia. If these relations were to worsen, it could adversely affect U.S. issuers as well as non-U.S. issuers that rely on the U.S. for trade. The U.S. has also experienced increased internal unrest and discord. If this trend were to continue, it may have an adverse impact on the U.S. economy and many of the issuers in which the Fund invests.

valuation as quoted by one or more data service providers. This conversion may result in a difference between the prices used to calculate the Fund's NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund's performance and the performance of the Underlying Index. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Consumer Services Industry Risk. The success of consumer product manufacturers and retailers (including food and drug retailers, general retailers, media, and travel and

leisure companies) is tied closely to the performance of the domestic and international economies, interest rates, exchange rates and consumer confidence. The consumer services industry depends heavily on disposable household income and consumer spending. Companies in the consumer services industry may be subject to severe competition, which may also have an adverse impact on their profitability. Changes in consumer demographics and preferences in the countries in which the issuers of securities held by the Fund are located and in the countries to which they export their products may affect the success of consumer products.

Management

For its investment advisory services to the Fund, BFA is paid a management fee from the Fund corresponding to the Fund's allocable portion of an aggregate management fee calculated based on the aggregate average daily net assets of the following iShares funds: iShares Global Clean Energy ETF, iShares Global Consumer Discretionary ETF, iShares Global Consumer Staples ETF, iShares Global Energy ETF, iShares Global Financials ETF, iShares Global Healthcare ETF, iShares Global Industrials ETF, iShares Global Infrastructure ETF, iShares Global Materials ETF, iShares Global Tech ETF, iShares Global Telecom ETF, iShares Global Timber & Forestry ETF, iShares Global Utilities ETF, iShares North American Natural Resources ETF, iShares North American Tech ETF, iShares North American Tech-Multimedia Networking ETF, iShares North American Tech-Software ETF and iShares PHLX Semiconductor ETF.

Based on assets of the iShares funds listed above as of March 31, 2018, for its investment advisory services to the Fund, BFA was paid a management fee from the Fund, as a percentage of the Fund's average daily net assets, at the annual rate of 0.47%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P Global 1200 Consumer Staples Index^TM (the “Underlying Index”), which measures the performance of companies that S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”), a subsidiary of S&P Global, Inc., deems to be part of the consumer staples sector of the economy and that SPDJI believes are important to global markets. It is a subset of the S&P Global 1200^TM. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the consumer staples industry or sector. The components of the Underlying Index are likely to change over time. As of March 31, 2018, the Underlying Index was comprised of stocks of companies in the following countries: Australia, Belgium, Brazil, Canada, Chilé, Denmark, France, Germany, Ireland, Japan, Mexico, the Netherlands, Norway, South Korea,

Sweden, Switzerland, the United Kingdom (the “U.K.”) and the U.S.

S-2

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

trading price, yield, total return and ability to meet its investment objective.

S-3

industry, group of industries, sector or asset class.

Consumer Staples Sector Risk. The consumer staples sector may be affected by, among other things, marketing campaigns, changes in consumer demands, government regulations and changes in commodity prices.

Equity Securities Risk. Equity securities are subject to changes in value, and their values may be more

volatile than those of other asset classes. The Underlying Index is comprised of common stocks, which generally subject their holders to more risks than holders of preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

S-4

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Retail Sub-Industry Risk. The retail sub-industry may be affected by changes in domestic and international

S-5

economies, consumer confidence, disposable household income and spending, and consumer tastes and preferences. Companies in the retail sub-industry face intense competition.

collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

More Information About the Fund

substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Consumer Staples Sector Risk. Companies in the consumer staples sector may be affected by the regulation of various product components and production methods, marketing campaigns and changes in the global economy, consumer spending and consumer demand. Tobacco companies, in particular, may be adversely affected by new laws, regulations and litigation. Household and personal products are particularly sensitive to increased competition, decreased demand due to changes in consumer preferences and brand diminution. Food products are subject to the risk that raw materials are accidentally or maliciously contaminated or that products are contaminated through the supply chain due to human error or equipment failure. Such incidents may result in loss of market share and loss of revenue for companies in the consumer staples sector. Companies in the consumer staples sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

security failures by or breaches of the systems of the Fund’s adviser, distributor and other service providers (including, but not limited to, index providers, fund accountants, custodians, transfer agents and administrators), market makers, Authorized Participants or the issuers of securities in which the Fund invests, have the ability to cause disruptions and impact business operations, potentially resulting in: financial losses, interference with the Fund’s ability to calculate its NAV, disclosure of confidential trading information, impediments to trading, submission of erroneous trades or erroneous creation or redemption orders, the inability of the Fund or its service providers to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. In addition, cyber attacks may render records of Fund assets and transactions, shareholder ownership of Fund shares, and other data integral to the functioning of the Fund inaccessible or inaccurate or incomplete. Substantial costs may be incurred by the Fund in order to resolve or prevent cyber incidents in the future. While the Fund has established business continuity plans in the event of, and risk management systems to prevent, such cyber attacks, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified and that prevention and remediation efforts will not be successful. Furthermore, the Fund cannot control the cyber security plans and systems put in place by service providers to the Fund, issuers in which the Fund invests, the Index Provider, market makers or Authorized Participants. The Fund and its shareholders could be negatively impacted as a result.

Responses to financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest, may limit future growth and economic recovery or may have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. In a referendum held on June 23, 2016, the U.K. resolved to leave the EU. The referendum may introduce significant uncertainties and instability in the financial markets as the U.K. negotiates its exit from the EU. Although the precise timeframe for the U.K.’s withdrawal is uncertain, on March 29, 2017, the U.K. initiated the withdrawal process by sending a formal notice of the country’s intention to withdraw from the EU. An agreement has been reached between the U.K. and the EU to continue negotiations on the U.K.’s exit from the EU. The outcome of negotiations remain uncertain.

Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

the Fund would have market exposure to such constituents and would be underexposed to the Underlying Index’s other constituents. Such errors may negatively or positively impact the Fund and its shareholders.

Market Trading Risk

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

■	Lower levels of liquidity and market efficiency;
■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;

■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements; and

■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the U.S.

international relations due to territorial disputes, historical animosities, defense concerns and other security concerns. These situations may cause uncertainty in the financial markets in these countries or geographic areas and may adversely affect the performance of the issuers to which the Fund has exposure. Heavy regulation of certain markets, including labor and product markets, may have an adverse effect on certain issuers. Such regulations may negatively affect economic growth or cause prolonged periods of recession. Many developed countries are heavily indebted and face rising healthcare and retirement expenses. In addition, price fluctuations of certain commodities and regulations impacting the import of commodities may negatively affect developed country economies.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

subject to political risk, including political instability, corruption and regional conflict with neighboring countries. North Korea and South Korea each have substantial military capabilities, and historical tensions between the two countries present the risk of war. Escalated tensions involving the two countries and any outbreak of hostilities between the two countries, or even the threat of an outbreak of hostilities, could have a severe adverse effect on the entire Asian region. In addition, many Asian countries are subject to social and labor risks associated with demands for improved political, economic and social conditions. These risks, among others, may adversely affect the value of the Fund’s investments.

iSHARES^® GLOBAL ENERGY ETF

Ticker: IXC

Stock Exchange: NYSE Arca

Investment Objective

The iShares Global Energy ETF (the “Fund”) seeks to track the investment results of an index composed of global equities in the energy sector.

Fees and Expenses

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

S-1

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P Global 1200 Energy Index^TM (the “Underlying Index”), which measures the performance of companies that S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”), a subsidiary of S&P Global, Inc., deems to be part of the energy sector of the economy and that SPDJI believes are important to global markets. It is a subset of the S&P Global 1200^TM. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the energy and oil and equipment services industries or sectors. The components of the Underlying Index are likely to change over time. As of March 31, 2018, the Underlying Index was comprised of stocks of companies in the following countries: Australia, Austria, Brazil, Canada, Chilé, China, Colombia, Finland, France, Italy, Japan, Norway, Portugal, Spain, the United Kingdom (the “U.K.”) and the U.S.

S-2

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

Commodity Risk. The Fund’s investments in certain companies, especially resource extraction and production companies, are sensitive to fluctuations in certain commodity markets, and changes in those markets may cause the Fund’s portfolio to lose value.

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more

S-3

than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class.

Energy Sector Risk. The market value of securities in the energy sector may decline for many reasons, including, among others, changes in energy prices, energy supply and demand, government

regulations and energy conservation efforts.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund

S-4

has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

current price of such an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

Oil Equipment and Services Sub-Industry Risk. Companies in the oil equipment and services sub-industry are affected by worldwide energy prices, exploration and production costs. Companies in the oil equipment and services sub-industry may have significant operations in areas at risk for natural disasters, social unrest and environmental damage. These companies may also be at risk for increased government regulation and

S-5

intervention, litigation, and negative publicity and public perception.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

burdens and the price or availability of certain commodities.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Purchase and Sale of Fund Shares

The Fund is an ETF. Individual shares of the Fund are listed on a national securities exchange. Most investors will buy and sell shares of the Fund through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than at NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 150,000 shares or multiples thereof (“Creation Units”) to Authorized Participants who have entered into agreements with the Fund's distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

More Information About the Fund

substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Commodity Risk. Companies whose performance is reflected in the Fund’s portfolio or Underlying Index may be adversely affected by changes or trends in commodity prices. Commodity prices may be influenced or characterized by unpredictable factors, including, where applicable, high volatility, changes in supply and demand relationships, weather, agriculture, trade, pestilence, political instability, changes in interest rates and monetary and other governmental policies, action and inaction, including price changes due to the imposition of tariffs by the U.S. and other countries. Securities of companies held by the Fund that are dependent on a single commodity, or are concentrated in a single commodity sector, may typically exhibit even higher volatility attributable to commodity prices.

ability to cause disruptions and impact business operations, potentially resulting in: financial losses, interference with the Fund’s ability to calculate its NAV, disclosure of confidential trading information, impediments to trading, submission of erroneous trades or erroneous creation or redemption orders, the inability of the Fund or its service providers to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. In addition, cyber attacks may render records of Fund assets and transactions, shareholder ownership of Fund shares, and other data integral to the functioning of the Fund inaccessible or inaccurate or incomplete. Substantial costs may be incurred by the Fund in order to resolve or prevent cyber incidents in the future. While the Fund has established business continuity plans in the event of, and risk management systems to prevent, such cyber attacks, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified and that prevention and remediation efforts will not be successful. Furthermore, the Fund cannot control the cyber security plans and systems put in place by service providers to the Fund, issuers in which the Fund invests, the Index Provider, market makers or Authorized Participants. The Fund and its shareholders could be negatively impacted as a result.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or

to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes. The Underlying Index is comprised of common stocks, which generally subject their holders to more risks than holders of preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Responses to financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest, may limit future growth and economic recovery or may have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. In a referendum held on June 23, 2016, the U.K. resolved to leave the EU. The referendum may introduce significant uncertainties and instability in the financial markets as the U.K. negotiates its exit from the EU. Although the precise timeframe for the U.K.’s withdrawal is uncertain, on March 29, 2017, the U.K. initiated the withdrawal process by sending a formal notice of the country’s intention to withdraw from the EU. An agreement has been reached between the U.K. and the EU to continue negotiations on the U.K.’s exit from the EU. The outcome of negotiations remain uncertain.

Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

impact the economies of these geographic areas or business operations of companies in these geographic areas, causing an adverse impact on the value of the Fund.

Market Trading Risk

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or for other reasons. In addition, trading in Fund shares on a

stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;

■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;

perception and world events in the regions that the companies operate (e.g., expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and repatriation of capital, military coups, social unrest, violence or labor unrest). Companies in the oil equipment and services sub-industry may have significant capital investments in, or engage in transactions involving, emerging market countries, which may heighten these risks.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell shares of mid-capitalization companies. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments.

North American Economic Risk. A decrease in imports or exports, changes in trade regulations or an economic recession in any North American country can have a significant economic effect on the entire North American region and on some or all of the North American countries in which the Fund invests.

The U.S. is Canada's and Mexico's largest trading and investment partner. The Canadian and Mexican economies are significantly affected by developments in the U.S. economy. Since the implementation of the North American Free Trade Agreement (“NAFTA”) in 1994 among Canada, the U.S. and Mexico, total merchandise trade among the three countries has increased. However, political developments in the U.S., including possible termination of NAFTA and imposition of tariffs by the U.S. on Canadian aluminum and steel, may have implications for the trade arrangements among the U.S., Mexico and Canada, which could negatively affect the value of securities held by the Fund. Policy and legislative changes in one country may have a significant effect on North American markets generally, as well as on the value of certain securities held by the Fund.

Threshold/Underinvestment Risk. If certain aggregate ownership thresholds are reached either through the actions of BFA and its affiliates or the Fund, or as a result of

third-party transactions, the ability of BFA and its affiliates on behalf of clients (including the Fund) to purchase or dispose of investments, or exercise rights or undertake business transactions, may be restricted by regulation or otherwise impaired. The capacity of the Fund to make investments in certain securities may be affected by the relevant threshold limits, and such limitations may have adverse effects on the liquidity and performance of the Fund’s portfolio holdings compared to the performance of the Underlying Index. This may increase the risk of the Fund being underinvested to the Underlying Index and increase the risk of tracking error.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using prevailing market rates on the date of valuation as quoted by

one or more data service providers. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

and net gain, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly) and of estates and trusts.

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

Dividends, interest and capital gains earned by the Fund with respect to securities issued by non-U.S. issuers may give rise to withholding, capital gains and other taxes

foreign tax credits passed through by the Fund if your Fund shares are loaned out pursuant to a securities lending agreement.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 150,000 shares or multiples thereof. Each “creator” or authorized participant (an “Authorized Participant”) has entered into an agreement with the Fund's distributor, BlackRock Investments, LLC (the “Distributor”), an affiliate of BFA.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Approximate Value of a Creation Unit		Creation Unit Size		Standard Creation/ Redemption Transaction Fee		Maximum Additional Charge for Creations*		Maximum Additional Charge for Redemptions*
$5,556,000		150,000		$600		7.0%		2.0%

*	As a percentage of the net asset value per Creation Unit, inclusive, in the case of redemptions, of the standard redemption transaction fee.

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P Global 1200 Financials Index^TM (the “Underlying Index”), which measures the performance of companies that S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”), a subsidiary of S&P Global, Inc., deems to be part of the financial sector of the economy and that SPDJI believes are important to global markets. It is a subset of the S&P Global 1200^TM. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the financials industry or sector. The components of the Underlying Index are likely to change over time. As of March 31, 2018, the Underlying Index was comprised of stocks of companies in the following countries: Australia, Austria, Belgium, Brazil, Canada, Chilé, China, Colombia, Denmark, Finland, France, Germany, Hong Kong, Ireland, Italy, Japan, Mexico, the Netherlands, Norway, Peru, Singapore, South Korea,

Spain, Sweden, Switzerland, Taiwan, the United Kingdom (the “U.K.”) and the U.S.

S-2

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders.

Insurance Industry Risk. The insurance industry may be significantly affected by changes in interest rates, catastrophic events, price and market competition, the imposition of premium rate caps, or other changes in government regulation or tax law, among other factors.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

S-5

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

In addition, the value of the securities or other assets in the Fund's portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund's shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

More Information About the Fund

substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Responses to financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest, may limit future growth and economic recovery or may have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. In a referendum held on June 23, 2016, the U.K. resolved to leave the EU. The referendum may introduce significant uncertainties and instability in the financial markets as the U.K. negotiates its exit from the EU. Although the precise timeframe for the U.K.’s withdrawal is uncertain, on March 29, 2017, the U.K. initiated the withdrawal process by sending a formal notice of the country’s intention to withdraw from the EU. An agreement has been reached between the U.K. and the EU to continue negotiations on the U.K.’s exit from the EU. The outcome of negotiations remain uncertain.

Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

Insurance Industry Risk. The insurance industry is subject to extensive government regulation in some countries and can be significantly affected by changes in interest rates, general economic conditions, price and market competition, the imposition of premium rate caps or other changes in government regulation or tax law. Certain segments of the insurance industry can be significantly affected by mortality and morbidity rates, environmental clean-up costs and catastrophic events such as earthquakes, hurricanes and terrorist acts.

Market Trading Risk

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or for other reasons. In addition, trading in Fund shares on a

stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

■	Lower levels of liquidity and market efficiency;
■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;
■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements; and

■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the U.S.

Risk of Investing in Developed Countries. Investment in developed country issuers may subject the Fund to regulatory, political, currency, security, economic and other

may cause uncertainty in the markets of these geographic areas and may adversely affect their economies.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

unemployment, currency devaluations and restrictions, and over-extension of credit. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia. Any adverse event in the Asian markets may have a significant adverse effect on some or all of the economies of the countries in which the Fund invests. Many Asian countries are subject to political risk, including political instability, corruption and regional conflict with neighboring countries. North Korea and South Korea each have substantial military capabilities, and historical tensions between the two countries present the risk of war. Escalated tensions involving the two countries and any outbreak of hostilities between the two countries, or even the threat of an outbreak of hostilities, could have a severe adverse effect on the entire Asian region. In addition, many Asian countries are subject to social and labor risks associated with demands for improved political, economic and social conditions. These risks, among others, may adversely affect the value of the Fund’s investments.

securities valuations and greater risks associated with custody of securities than developed markets. In addition, emerging markets often have greater risk of capital controls through such measures as taxes or interest rate control than developed markets. Certain emerging market countries may also lack the infrastructure necessary to attract large amounts of foreign trade and investment.

Shareholder Information

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations

and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section below) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

Dividends and Distributions

Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates. Long-term capital gains and qualified dividend income are generally eligible for taxation at a maximum rate of 15% or 20% for non-corporate shareholders, depending on whether their income exceeds certain threshold amounts. In addition, a 3.8% U.S. federal Medicare contribution tax is imposed on “net investment income,” including, but not limited to, interest, dividends, and net gain, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly) and of estates and trusts.

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder's cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

identification number of each substantial U.S. owner or provide certifications of no substantial U.S. ownership unless certain exceptions apply.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, price movement and other costs and expenses related to cash transactions (which may, in certain instances, be based on a good faith estimate of transaction costs). Investors who use the services of a broker or other financial intermediary to acquire or dispose of Fund shares may pay fees for such services.

Approximate Value of a Creation Unit		Creation Unit Size		Standard Creation/ Redemption Transaction Fee		Maximum Additional Charge for Creations*		Maximum Additional Charge for Redemptions*

iSHARES^® GLOBAL HEALTHCARE ETF

Ticker: IXJ

Stock Exchange: NYSE Arca

Investment Objective

The iShares Global Healthcare ETF (the “Fund”) seeks to track the investment results of an index composed of global equities in the healthcare sector.

Fees and Expenses

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P Global 1200 Health Care Index^TM (the “Underlying Index”), which measures the performance of companies that S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”), a subsidiary of S&P Global, Inc., deems to be a part of the healthcare sector of the economy and that SPDJI believes are important to global markets. It is a subset of the S&P Global 1200^TM. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the healthcare industry or sector. The components of the Underlying Index are likely to change over time. As of March 31, 2018, the Underlying Index was comprised of stocks of companies in the following countries: Australia, Belgium, Canada, Denmark, France, Germany, Japan, the Netherlands, South Korea, Spain, Switzerland, the United Kingdom (the “U.K.”) and the U.S.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s

investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

S-2

Index, but which BFA believes will help the Fund track the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

Asset Class Risk. Securities and other assets in the Underlying Index or in the

Fund's portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes.

Biotechnology Industry Risk. Biotechnology companies face intense competition and potentially rapid product obsolescence. Biotechnology companies may be adversely affected by the loss or impairment of intellectual property rights or changes in government regulations.

S-3

concentrated in the securities of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class.

risks than holders of preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Healthcare Sector Risk. The profitability of companies in the healthcare sector may be affected by government regulations and government healthcare programs, increases or decreases in the cost of medical products and services, an increased emphasis on outpatient services, and product liability claims, among other factors. Many healthcare companies are heavily dependent on patent protection, and the expiration of a company’s patent may adversely affect that company’s profitability. Healthcare companies are subject to competitive forces that may result in price discounting, and may be thinly capitalized and susceptible to product obsolescence.

S-4

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

S-5

seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Pharmaceuticals Industry Risk. Companies in the pharmaceuticals industry may be affected by industry competition, dependency on a limited number of products, obsolescence of products, government approvals and regulations, loss or impairment of intellectual property rights and litigation regarding product liability.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Biotechnology Industry Risk. Companies in the biotechnology industry spend heavily on research and development, and their products or services may not prove commercially successful or may become obsolete quickly. The biotechnology industry is subject to a significant amount of governmental regulation, and changes in governmental policies and the need for regulatory approvals may have a material adverse effect on this industry. Companies in the biotechnology industry are subject to risks of new technologies and competitive pressures and are heavily dependent on patents and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

financial losses, interference with the Fund’s ability to calculate its NAV, disclosure of confidential trading information, impediments to trading, submission of erroneous trades or erroneous creation or redemption orders, the inability of the Fund or its service providers to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. In addition, cyber attacks may render records of Fund assets and transactions, shareholder ownership of Fund shares, and other data integral to the functioning of the Fund inaccessible or inaccurate or incomplete. Substantial costs may be incurred by the Fund in order to resolve or prevent cyber incidents in the future. While the Fund has established business continuity plans in the event of, and risk management systems to prevent, such cyber attacks, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified and that prevention and remediation efforts will not be successful. Furthermore, the Fund cannot control the cyber security plans and systems put in place by service providers to the Fund, issuers in which the Fund invests, the Index Provider, market makers or Authorized Participants. The Fund and its shareholders could be negatively impacted as a result.

financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. In a referendum held on June 23, 2016, the U.K. resolved to leave the EU. The referendum may introduce significant uncertainties and instability in the financial markets as the U.K. negotiates its exit from the EU. Although the precise timeframe for the U.K.’s withdrawal is uncertain, on March 29, 2017, the U.K. initiated the withdrawal process by sending a formal notice of the country’s intention to withdraw from the EU. An agreement has been reached between the U.K. and the EU to continue negotiations on the U.K.’s exit from the EU. The outcome of negotiations remain uncertain.

Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

Market Trading Risk

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

■	Lower levels of liquidity and market efficiency;
■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;
■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements; and

■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the U.S.

Pharmaceuticals Industry Risk. Companies in the pharmaceuticals industry are subject to competitive forces that may make it difficult to raise prices of their products and, in fact, may result in price discounting. The profitability of some companies in the pharmaceuticals industry may be dependent on a relatively limited number of products. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the pharmaceuticals industry are subject to government approvals, regulation and reimbursement rates. The process of obtaining government approvals may be long and costly. Many companies in the pharmaceuticals industry are heavily dependent on

patents and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Companies in the pharmaceuticals industry may be subject to extensive litigation based on product liability and similar claims.

investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

S-2

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of

institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units (as defined in the Purchase and Sale of Fund Shares section of the Prospectus), Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for exchange-traded funds (“ETFs”), such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes.

Capital Goods Industry Risk. Companies in the capital goods industry may be affected by fluctuations in the business cycle. Many capital goods are sold internationally, and companies in this industry may be affected by market conditions in other countries and regions.

S-3

As a result, the Fund's NAV may change quickly and without warning.

Index-Related Risk. There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the Fund will achieve its

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

S-4

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Risk of Investing in the United States. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on

the securities to which the Fund has exposure.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

differences in transaction costs, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or interest, tax gains or losses, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Capital Goods Industry Risk. Companies in the capital goods industry may be affected by fluctuations in the business cycle and by other factors affecting manufacturing demands. The capital goods industry depends heavily on corporate spending. Companies in the capital goods industry may perform well during times of economic expansion, but as economic conditions worsen, the demand for capital goods may decrease. Many capital goods are sold internationally, and companies in this industry may be affected by market conditions in other countries and regions.

trades or erroneous creation or redemption orders, the inability of the Fund or its service providers to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. In addition, cyber attacks may render records of Fund assets and transactions, shareholder ownership of Fund shares, and other data integral to the functioning of the Fund inaccessible or inaccurate or incomplete. Substantial costs may be incurred by the Fund in order to resolve or prevent cyber incidents in the future. While the Fund has established business continuity plans in the event of, and risk management systems to prevent, such cyber attacks, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified and that prevention and remediation efforts will not be successful. Furthermore, the Fund cannot control the cyber security plans and systems put in place by service providers to the Fund, issuers in which the Fund invests, the Index Provider, market makers or Authorized Participants. The Fund and its shareholders could be negatively impacted as a result.

on June 23, 2016, the U.K. resolved to leave the EU. The referendum may introduce significant uncertainties and instability in the financial markets as the U.K. negotiates its exit from the EU. Although the precise timeframe for the U.K.’s withdrawal is uncertain, on March 29, 2017, the U.K. initiated the withdrawal process by sending a formal notice of the country’s intention to withdraw from the EU. An agreement has been reached between the U.K. and the EU to continue negotiations on the U.K.’s exit from the EU. The outcome of negotiations remain uncertain.

Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

correlation between the Fund’s portfolio and the Underlying Index, any transaction costs and market exposure arising from such portfolio rebalancing will be borne directly by the Fund and its shareholders. Unscheduled rebalances to the Underlying Index may expose the Fund to additional tracking error risk, which is the risk that the Fund's returns may not track those of the Underlying Index. Therefore, errors and additional ad hoc rebalances carried out by the Index Provider or its agents to the Underlying Index may increase the costs to and the tracking error risk of the Fund.

Industrials Sector Risk. The value of securities issued by companies in the industrials sector may be adversely affected by supply and demand changes related to their specific products or services and industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Global events and changes in government regulations, economic conditions and exchange rates may adversely affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage and product liability claims. The industrials sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors. Aerospace and defense companies, a component of the industrials sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on government demand for their products and services. Thus, the financial condition of, and investor interest in, aerospace and defense companies are heavily influenced by governmental defense spending policies, which are typically under pressure from efforts to control government budgets. Transportation stocks, a component of the industrials sector, are cyclical and can be significantly affected by economic changes, fuel prices, labor relations and insurance costs. Transportation companies in certain countries may also be subject to significant government regulation and oversight, which may adversely affect their businesses. Companies in the industrials sector, particularly aerospace and defense companies, may also be adversely affected by government spending policies because companies in this sector tend to rely to a significant extent on government demand for their products and services.

market cycles, the performance of large-capitalization companies has trailed the overall performance of the broader securities markets.

Market Trading Risk

between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

■	Lower levels of liquidity and market efficiency;
■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;
■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements; and

■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the U.S.

have a negative impact on economies of certain developed countries, although economies of individual developed countries can be impacted by slowdowns in other sectors. In the past, certain developed countries have been targets of terrorism, and some geographic areas in which the Fund invests have experienced strained international relations due to territorial disputes, historical animosities, defense concerns and other security concerns. These situations may cause uncertainty in the financial markets in these countries or geographic areas and may adversely affect the performance of the issuers to which the Fund has exposure. Heavy regulation of certain markets, including labor and product markets, may have an adverse effect on certain issuers. Such regulations may negatively affect economic growth or cause prolonged periods of recession. Many developed countries are heavily indebted and face rising healthcare and retirement expenses. In addition, price fluctuations of certain commodities and regulations impacting the import of commodities may negatively affect developed country economies.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

the entire Asian region, as well as on major trading partners outside Asia. Any adverse event in the Asian markets may have a significant adverse effect on some or all of the economies of the countries in which the Fund invests. Many Asian countries are subject to political risk, including political instability, corruption and regional conflict with neighboring countries. North Korea and South Korea each have substantial military capabilities, and historical tensions between the two countries present the risk of war. Escalated tensions involving the two countries and any outbreak of hostilities between the two countries, or even the threat of an outbreak of hostilities, could have a severe adverse effect on the entire Asian region. In addition, many Asian countries are subject to social and labor risks associated with demands for improved political, economic and social conditions. These risks, among others, may adversely affect the value of the Fund’s investments.

Portfolio Holdings Information

Management

listed above as of March 31, 2018, for its investment advisory services to the Fund, BFA was paid a management fee from the Fund, as a percentage of the Fund's average daily net assets, at the annual rate of 0.47%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Alan Mason has been employed by BFA as a portfolio manager since 1991. Mr. Mason has been a Portfolio Manager of the Fund since 2016.

Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

The Fund invests in non-U.S. securities. Foreign currency exchange rates with respect to the portfolio securities denominated in non-U.S. currencies are generally

determined as of 4:00 p.m., London time. Non-U.S. securities held by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants (as defined in the Creations and Redemptions section of this Prospectus) will not be able to purchase or redeem Fund shares.

Dividends and Distributions

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

Fund at the close of a year consists of non-U.S. stocks or securities (generally, for this purpose, depositary receipts, no matter where traded, of non-U.S. companies are treated as “non-U.S.”), generally the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

In the event of a system failure or other interruption, including disruptions at market makers or Authorized Participants, orders to purchase or redeem Creation Units either

may not be executed according to the Fund's instructions or may not be executed at all, or the Fund may not be able to place or change orders.

Approximate Value of a Creation Unit		Creation Unit Size		Standard Creation/ Redemption Transaction Fee		Maximum Additional Charge for Creations*		Maximum Additional Charge for Redemptions*
$4,520,000		50,000		$2,200		7.0%		2.0%

*	As a percentage of the net asset value per Creation Unit, inclusive, in the case of redemptions, of the standard redemption transaction fee.

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P Global Infrastructure Index^TM (the “Underlying Index”), which is designed to track performance of the stocks of large infrastructure companies in developed or emerging markets that must be domiciled in developed markets, or whose stocks are listed on developed market exchanges around the world. The Underlying Index includes companies involved in utilities, energy and transportation infrastructure, such as the management or ownership of oil and gas storage and transportation; airport services; highways and rail tracks; marine ports and services; and electric, gas and water utilities. As of March 31, 2018, the Underlying Index was comprised of stocks of companies in the following countries: Australia, Brazil, Canada, Chilé, China, France, Germany, Hong Kong, Italy, Mexico, New Zealand, Singapore, Spain, Switzerland, the United Kingdom (the “U.K.”) and the U.S. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a

significant portion of the Underlying Index is represented by securities of companies in the energy, infrastructure and utilities industries or sectors. The components of the Underlying Index are likely to change over time.

The Fund generally will invest at least 90% of its assets in the component securities of the Underlying Index and in

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

capitalization companies has trailed the overall performance of the broader securities markets.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Risk of Investing in Developed Countries. The Fund’s investment in developed country issuers may subject the Fund to regulatory, political, currency, security, economic and other

risks associated with developed countries. Developed countries tend to represent a significant portion of the global economy and have generally experienced slower economic growth than some less developed countries. Certain developed countries have experienced security concerns, such as terrorism and strained international relations. Incidents involving a country’s or region’s security may cause uncertainty in its markets and may adversely affect its economy and the Fund’s investments. In addition, developed countries may be adversely impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, debt burdens and the price or availability of certain commodities.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns, such as terrorism and strained international relations. Incidents involving a country's

S-6

or region's security may cause uncertainty in its markets and may adversely affect its economy and the Fund's investments.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Utilities Sector Risk. The utilities sector is subject to significant government regulation and oversight.

Deregulation, however, may subject utility companies to greater competition and may reduce their profitability. Companies in the utilities sector may be adversely affected due to increases in fuel and operating costs, rising costs of financing capital construction and the cost of complying with regulations, among other factors.

Purchase and Sale of Fund Shares

The Fund is an ETF. Individual shares of the Fund are listed on a national securities exchange. Most investors will buy and sell shares of the Fund through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than at NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 100,000 shares or multiples thereof (“Creation Units”) to Authorized Participants who have entered into agreements with the Fund's distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Changes in imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro (the common currency of certain EU countries), the default or threat of default by an EU member state on its sovereign debt and/or an economic recession in an EU member state may have a significant adverse effect on the economies of EU member states and their trading partners. The European financial markets have historically experienced volatility and adverse trends due to concerns about economic downturns or rising government debt levels in several European countries, including, but not limited to, Austria, Belgium, Cyprus, France, Greece, Ireland, Italy, Portugal, Spain and Ukraine. These events have adversely affected the exchange rate of the euro and may continue to significantly affect European countries.

Responses to financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest, may limit future growth and economic recovery or may have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. In a referendum held on June 23, 2016, the U.K. resolved to leave the EU. The referendum may introduce significant uncertainties and instability in the financial markets as the U.K. negotiates its exit from the EU. Although the precise timeframe for the U.K.’s withdrawal is uncertain, on March 29, 2017, the U.K. initiated the withdrawal process by sending a formal notice of the country’s intention to withdraw from the EU. An agreement has been reached between the U.K. and the EU to continue negotiations on the U.K.’s exit from the EU. The outcome of negotiations remain uncertain.

Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

its related data, and they do not guarantee that the Underlying Index will be in line with the Index Provider’s methodology. BFA’s mandate as described in this Prospectus is to manage the Fund consistently with the Underlying Index provided by the Index Provider to BFA. BFA does not provide any warranty or guarantee against the Index Provider’s or any agent’s errors. Errors in respect of the quality, accuracy and completeness of the data used to compile the Underlying Index may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, particularly where the indices are less commonly used as benchmarks by funds or managers. Therefore, gains, losses or costs associated with errors of the Index Provider or its agents will generally be borne by the Fund and its shareholders. For example, during a period where the Underlying Index contains incorrect constituents, the Fund would have market exposure to such constituents and would be underexposed to the Underlying Index’s other constituents. Such errors may negatively or positively impact the Fund and its shareholders.

Infrastructure Industry Risk. Companies in the infrastructure industry may be subject to a variety of factors that could adversely affect their business or operations, including high interest costs in connection with capital construction programs, high degrees of leverage, costs associated with governmental, environmental and other regulations, the effects of economic slowdowns, increased competition from other providers of services, uncertainties concerning costs, the level of government spending on infrastructure projects, and other factors. Infrastructure companies may be adversely affected by commodity price volatility, changes in exchange rates, import controls, depletion of resources, technological developments, and labor relations. There is also the risk that corruption may negatively affect publicly funded infrastructure projects, especially in emerging markets, resulting in delays and cost overruns. Infrastructure issuers can be significantly affected by government spending policies because companies involved in this industry rely to a significant extent on U.S. and other government demand for their products.

investments in, or engage in transactions involving, emerging market countries, which may heighten these risks.

Interest Rate Risk. Rising interest rates could result in higher costs of capital for infrastructure companies, which could negatively impact their ability to meet payment obligations.

Transportation Risk. The stock prices of companies in the transportation industry group are affected by both supply and demand for their specific product. Government regulation, world events and economic conditions may affect the performance of companies in the transportation sector.

Oil and Gas Risk. The profitability of oil and gas companies is related to worldwide energy prices, exploration, and production spending.

expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures, credit deterioration of the issuer or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline. An issuer may also be subject to risks associated with the countries, states and regions in which the issuer resides, invests, sells products, or otherwise conducts operations.

Market Trading Risk

and market liquidity and wider if the Fund has less trading volume and market liquidity. In addition, increased market volatility may cause wider spreads. There may also be regulatory and other charges that are incurred as a result of trading activity. Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments through a brokerage account.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

equipment or products have been rendered obsolete by technological innovations; or be subject to increased costs because of the scarcity of certain fuels or the effects of man-made or natural disasters. Existing and future regulations or legislation may make it difficult for utility companies to operate profitably. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. In certain countries, regulatory authorities may also restrict utility companies’ access to new markets, thereby diminishing these companies’ long-term prospects. There is no assurance that regulatory authorities will grant rate increases in the future or that such increases will be adequate to permit the payment of dividends on stocks issued by a utility company. Energy conservation and changes in climate policy may also have a significant adverse impact on the revenues and expenses of utility companies.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

military capabilities, and historical tensions between the two countries present the risk of war. Escalated tensions involving the two countries and any outbreak of hostilities between the two countries, or even the threat of an outbreak of hostilities, could have a severe adverse effect on the entire Asian region. In addition, many Asian countries are subject to social and labor risks associated with demands for improved political, economic and social conditions. These risks, among others, may adversely affect the value of the Fund’s investments.

including possible termination of NAFTA and imposition of tariffs by the U.S. on Canadian aluminum and steel, may have implications for the trade arrangements among the U.S., Mexico and Canada, which could negatively affect the value of securities held by the Fund. Policy and legislative changes in one country may have a significant effect on North American markets generally, as well as on the value of certain securities held by the Fund.

Dividends and Distributions

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general

information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 100,000 shares or multiples thereof. Each “creator” or authorized participant (an “Authorized Participant”) has entered into an agreement with the Fund's distributor, BlackRock Investments, LLC (the “Distributor”), an affiliate of BFA.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P Global 1200 Materials Index^TM (the “Underlying Index”), which measures the performance of companies that S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”), a subsidiary of S&P Global, Inc., deems to be part of the materials sector of the economy and that SPDJI believes are important to global markets. It is a subset of the S&P Global 1200^TM. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the chemicals, materials, and metals and mining industries or sectors. The components of the Underlying Index are likely to change over time. As of March 31, 2018, the Underlying Index was comprised of stocks of companies in the following countries: Australia, Austria, Belgium, Brazil, Canada, Chilé, Denmark, Finland, France, Germany, Ireland, Japan, Luxembourg, Mexico, the Netherlands, Norway, Peru, South

Korea, Sweden, Switzerland, Taiwan, the United Kingdom (the “U.K.”) and the U.S.

S-2

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Chemicals Industry Risk. The chemicals industry may be significantly affected by intense competition, product obsolescence, raw materials prices, and government regulation, and may be subject to risks associated with the production, handling and disposal of hazardous components, and litigation

S-3

arising out of environmental contamination.

Participants or issuers of securities in which the Fund invests.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund

S-4

has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Materials Sector Risk. Companies in the materials sector may be adversely impacted by the volatility of commodity prices, changes in exchange rates, depletion of resources, over-production, litigation and changes in government regulations, among other factors.

Metals and Mining Industry Risk. Companies in the metals and mining industry are susceptible to fluctuations in worldwide metal prices, and extraction and production costs. In addition, metals and mining companies may have significant operations in areas at risk for social and political unrest, security concerns and environmental damage. These companies may also be at risk for increased government regulation and intervention. Such risks may adversely affect the issuers to which the Fund has exposure.

S-5

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

uncertainty in its markets and may adversely affect its economy and the Fund’s investments. In addition, developed countries may be adversely impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, debt burdens and the price or availability of certain commodities.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Tracking Error Risk. The Fund may be subject to tracking error, which is the divergence of the Fund’s performance

S-6

from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences (including, as applicable, differences between a security’s price at the local market close and the Fund's valuation of a security at the time of calculation of the Fund's NAV), differences in transaction costs, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or interest, tax gains or losses, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

Valuation Risk. The price the Fund could receive upon the sale of a security

or other asset may differ from the Fund's valuation of the security or other asset and from the value used by the Underlying Index, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. In addition, the value of the securities or other assets in the Fund's portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund's shares. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Chemicals Industry Risk. The Fund invests in companies in the chemicals industry. The success of companies in the chemicals industry can be significantly affected by intense competition, product obsolescence, raw materials prices, and government regulation. As regulations are developed and enforced, chemicals companies could be required to alter or cease production of a product, pay fines, pay for cleaning up a disposal site or agree to restrictions on their operations. In addition, chemicals companies may be subject to risks associated with production, handling, and disposal, as some of the materials and processes used by these companies involve hazardous components.

Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

Apart from scheduled rebalances, the Index Provider or its agents may carry out additional ad hoc rebalances to the Underlying Index in order, for example, to correct

an error in the selection of index constituents. When the Underlying Index is rebalanced and the Fund in turn rebalances its portfolio to attempt to increase the correlation between the Fund’s portfolio and the Underlying Index, any transaction costs and market exposure arising from such portfolio rebalancing will be borne directly by the Fund and its shareholders. Unscheduled rebalances to the Underlying Index may expose the Fund to additional tracking error risk, which is the risk that the Fund's returns may not track those of the Underlying Index. Therefore, errors and additional ad hoc rebalances carried out by the Index Provider or its agents to the Underlying Index may increase the costs to and the tracking error risk of the Fund.

Market Trading Risk

periods of significant market volatility, may result in trading prices for shares of the Fund that differ significantly from its NAV. Authorized Participants may be less willing to create or redeem Fund shares if there is a lack of an active market for such shares or its underlying investments, which may contribute to the Fund’s shares trading at a premium or discount to NAV.

Metals and Mining Industry Risk. The Fund will invest in securities that are issued by and/or have exposure to, companies primarily involved in the metals and mining industry. Investments in metals and mining companies may be speculative and subject to greater price volatility than investments in other types of companies. The profitability of companies in the metals and mining industry is related to, among other things, worldwide metal prices and extraction and production costs. Worldwide metal prices may fluctuate substantially over short periods of time, and as a result, the Fund’s share price may be more volatile than other types of investments. In addition, metals and mining companies may be significantly affected by changes in global demand for certain metals, economic developments, energy conservation, the success of exploration projects, changes in exchange rates, interest rates, economic conditions, tax treatment, trade treaties, and government regulation and intervention, and events in the regions that the companies to which the Fund has exposure operate (e.g., expropriation, nationalization, confiscation of assets and property, the imposition of restrictions on foreign investments or repatriation of capital, military coups, social or political unrest, violence and labor unrest). Metals and mining companies may also be subject to the effects of competitive pressures in the metals and mining industry.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the

loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund. BlackRock Institutional Trust Company, N.A., the Fund's securities lending agent, will take into account the tax impact to shareholders of substitute payments for dividends when managing the Fund's securities lending program.

used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Management

management fee is calculated as follows: 0.48% per annum of the aggregate net assets less than or equal to $10.0 billion, plus 0.43% per annum of the aggregate net assets over $10.0 billion, up to and including $20.0 billion, plus 0.38% per annum of the aggregate net assets in excess of $20.0 billion. Based on assets of the iShares funds listed above as of March 31, 2018, for its investment advisory services to the Fund, BFA was paid a management fee from the Fund, as a percentage of the Fund's average daily net assets, at the annual rate of 0.47%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Shareholder Information

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Equity investments and other instruments for which market quotations are readily available, as well as investments in an underlying fund, if any, are valued at market

value, which is generally determined using the last reported official closing price or, if a reported closing price is not available, the last traded price on the exchange or market on which the security is primarily traded at the time of valuation.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using prevailing market rates on the date of valuation as quoted by

one or more data service providers. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P Global 1200 Information Technology Index^TM (the “Underlying Index”), which measures the performance of companies that S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”), a subsidiary of S&P Global, Inc., deems to be part of the information technology sector of the economy and that SPDJI believes are important to global markets. It is a subset of the S&P Global 1200^TM. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the information technology and technology industries or sectors. The components of the Underlying Index are likely to change over time. As of March 31, 2018, the Underlying Index was comprised of stocks of companies in the following countries: Australia, Austria, Brazil, Canada, China, Finland, France, Germany, Italy, Japan, the Netherlands, South Korea, Spain,

Sweden, Taiwan, the United Kingdom (the “U.K.”) and the U.S.

to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

S-4

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive

positions under any market conditions, including declining markets.

Semiconductor Industry Risk. Semiconductor companies may have limited product lines, markets, financial resources or personnel. Semiconductor companies typically face intense competition, potentially rapid product obsolescence and high capital costs. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights. Semiconductor companies are also affected by the economic performance of their customers.

Structural Risk. The countries in which the Fund invests may be subject to

considerable degrees of economic, political and social instability.

Technology Sector Risk. Technology companies, including information technology companies, may have limited product lines, markets, financial resources or personnel. Technology companies typically face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by the loss or impairment of those rights.

More Information About the Fund

substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Apart from scheduled rebalances, the Index Provider or its agents may carry out additional ad hoc rebalances to the Underlying Index in order, for example, to correct

During a general market downturn, multiple asset classes may be negatively affected. Changes in market conditions and interest rates generally do not have the same impact on all types of securities and instruments.

Market Trading Risk

NAV, BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long term (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs). While the creation/redemption feature is designed to make it more likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund's NAV due to timing reasons, supply and demand imbalances and other factors. In addition, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants, or other market participants, and during periods of significant market volatility, may result in trading prices for shares of the Fund that differ significantly from its NAV. Authorized Participants may be less willing to create or redeem Fund shares if there is a lack of an active market for such shares or its underlying investments, which may contribute to the Fund’s shares trading at a premium or discount to NAV.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

■	Lower levels of liquidity and market efficiency;
■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;
■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements; and

■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the U.S.

as non-U.S. issuers that rely on the U.S. for trade. The U.S. has also experienced increased internal unrest and discord. If this trend were to continue, it may have an adverse impact on the U.S. economy and many of the issuers in which the Fund invests.

Semiconductor Industry Risk. The Fund invests in semiconductor companies, which face intense competition, both domestically and internationally, and such competition may have an adverse effect on profit margins. Semiconductor companies may have limited product lines, markets, financial resources or personnel. The products of semiconductor companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Capital equipment expenditures could be substantial, and equipment generally suffers from rapid obsolescence. Companies in the semiconductor industry are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights, would adversely affect the profitability of these companies.

Technology Sector Risk. Technology companies, including information technology companies, face intense competition, both domestically and internationally, which may have an adverse effect on a company’s profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector are heavily dependent on patent and other intellectual property rights. A technology company’s loss or impairment of these rights may adversely affect the company’s profitability. The technology sector may also be adversely affected by changes or trends in commodity prices, which may be influenced or characterized by unpredictable factors.

Transportation Infrastructure Industry Risk. Issuers in the transportation infrastructure industry may be adversely affected by economic changes, increases in fuel and operating costs, labor relations, and insurance costs. Transportation companies in certain countries may also be subject to significant government regulation and oversight, which may adversely affect their businesses. Other risk factors that may affect the transportation infrastructure industry include the risk of increases in fuel and other operating costs and the effects of regulatory changes or other government decisions.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

effect on the economies of EU member states and their trading partners. The European financial markets have historically experienced volatility and adverse trends due to concerns about economic downturns or rising government debt levels in several European countries, including, but not limited to, Austria, Belgium, Cyprus, France, Greece, Ireland, Italy, Portugal, Spain and Ukraine. These events have adversely affected the exchange rate of the euro and may continue to significantly affect European countries.

Responses to financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest, may limit future growth and economic recovery or may have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. In a referendum held on June 23, 2016, the U.K. resolved to leave the EU. The referendum may introduce significant uncertainties and instability in the financial markets as the U.K. negotiates its exit from the EU. Although the precise timeframe for the U.K.’s withdrawal is uncertain, on March 29, 2017, the U.K. initiated the withdrawal process by sending a formal notice of the country’s intention to withdraw from the EU. An agreement has been reached between the U.K. and the EU to continue negotiations on the U.K.’s exit from the EU. The outcome of negotiations remain uncertain.

Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P Global 1200 Telecommunications Services Index^TM (the “Underlying Index”), which measures the performance of companies that S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”), a subsidiary of S&P Global, Inc., deems to be a part of the telecommunications sector of the economy and that SPDJI believes are important to global markets. It is a subset of the S&P Global 1200^TM. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the telecommunications industry or sector. The components of the Underlying Index are likely to change over time. As of March 31, 2018, the Underlying Index was comprised of stocks of companies in the following countries: Australia, Belgium, Canada, China, Denmark, France, Germany, Italy, Japan, Luxembourg, Mexico, the Netherlands, Norway, Singapore, Spain, Sweden, Switzerland, Taiwan, the United Kingdom (the “U.K.”) and the U.S.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s

Fund invests have the ability to cause disruptions and negatively impact the Fund’s business operations, potentially resulting in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cyber security plans and systems of the Fund’s service providers, the Index Provider, market makers, Authorized Participants or issuers of securities in which the Fund invests.

with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

National Closed Market Trading Risk. To the extent that the underlying

S-4

securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of such an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Telecommunications Sector Risk. Companies in the telecommunications sector may be affected by industry competition, substantial capital requirements, government regulation and obsolescence of telecommunications products and services due to technological advancement.

differences in timing of the accrual of or the valuation of dividends or interest, tax gains or losses, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make network services unavailable to intended users). Cyber security failures by or breaches of the systems of the Fund’s adviser, distributor and other service providers (including, but not limited to, index providers, fund accountants, custodians, transfer agents and administrators), market makers, Authorized Participants or the issuers of securities in which the Fund invests, have the ability to cause disruptions and impact business operations, potentially resulting in: financial losses, interference with the Fund’s ability to calculate its NAV, disclosure of confidential trading information, impediments to trading, submission of erroneous trades or erroneous creation or redemption orders, the inability of the Fund or its service providers to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. In addition, cyber attacks may render records of Fund assets and transactions, shareholder ownership of Fund shares, and other data integral to the functioning of the Fund inaccessible or inaccurate or incomplete. Substantial costs may be incurred by the Fund in order to resolve or prevent cyber incidents in the future. While the Fund has established business continuity plans in the event of, and risk management systems to prevent, such cyber attacks, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified and that prevention and remediation efforts will not be successful. Furthermore, the Fund cannot control the cyber security plans and systems put in place by service providers to the Fund, issuers in which the Fund invests, the Index Provider, market makers or Authorized Participants. The Fund and its shareholders could be negatively impacted as a result.

affected the exchange rate of the euro and may continue to significantly affect European countries.

Responses to financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest, may limit future growth and economic recovery or may have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. In a referendum held on June 23, 2016, the U.K. resolved to leave the EU. The referendum may introduce significant uncertainties and instability in the financial markets as the U.K. negotiates its exit from the EU. Although the precise timeframe for the U.K.’s withdrawal is uncertain, on March 29, 2017, the U.K. initiated the withdrawal process by sending a formal notice of the country’s intention to withdraw from the EU. An agreement has been reached between the U.K. and the EU to continue negotiations on the U.K.’s exit from the EU. The outcome of negotiations remain uncertain.

Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

Market Trading Risk

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

■	Lower levels of liquidity and market efficiency;

■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;
■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements; and

■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the U.S.

certain commodities and regulations impacting the import of commodities may negatively affect developed country economies.

Telecommunications Sector Risk. The telecommunications sector of a country's economy is often subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new regulatory requirements may negatively affect the business of telecommunications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. The domestic telecommunications market is characterized by increasing competition and regulation by the U.S. Federal Communications Commission and various state regulatory authorities. Companies in the telecommunications sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in developing new products and services using new technology. Technological innovations may make the products and services of certain telecommunications companies obsolete. Telecommunications providers are generally required to obtain franchises or licenses

in order to provide services in a given location. Licensing and franchise rights in the telecommunications sector are limited, which may provide an advantage to certain participants. Limited availability of such rights, high barriers to market entry and regulatory oversight, among other factors, have led to consolidation of companies within the sector, which could lead to further regulation or other negative effects in the future.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

derivatives as well as repurchase agreements and securities lending agreements. The restrictions prevent the Fund from closing out a qualified financial contract during a specified time period if the counterparty is subject to resolution proceedings and prohibit the Fund from exercising default rights due to a receivership or similar proceeding of an affiliate of the counterparty. Implementation of these requirements may increase credit and other risks to the Fund.

instability, greater risk of a market shutdown and more governmental limitations on foreign investments in emerging market countries than are typically found in more developed markets. Additionally, the risk of nationalization of private assets is greater in emerging market countries than developed countries. Moreover, emerging markets often have less uniformity in accounting and reporting requirements, less reliable securities valuations and greater risks associated with custody of securities than developed markets. In addition, emerging markets often have greater risk of capital controls through such measures as taxes or interest rate control than developed markets. Certain emerging market countries may also lack the infrastructure necessary to attract large amounts of foreign trade and investment.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of

business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and

thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(a)(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(a)(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P Global Timber & Forestry Index^TM (the “Underlying Index”), which is comprised of approximately 25 of the largest publicly-traded companies engaged in the ownership, management or upstream supply chain of forests and timberlands. These include forest products companies, timber real estate investment trusts (“REITs”), paper products companies, paper packaging companies and agricultural products companies. Because many securities included in the Underlying Index may be issued by specialized REITs and forest products companies, the Fund is concentrated in the specialized REITs and forest products industries. As of March 31, 2018, the Underlying Index was comprised of stocks of companies in the following countries: Brazil, Canada, Finland, Ireland, Japan, South Africa, Sweden, the United Kingdom (the “U.K.”) and the U.S. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the

Underlying Index is represented by securities of companies in the materials, natural resources, real estate and timber and forestry industries or sectors. The components of the Underlying Index are likely to change over time.

The Fund generally will invest at least 90% of its assets in the component

S-2

securities of the Underlying Index and in investments that have economic characteristics that are substantially identical to the component securities of the Underlying Index (i.e., depositary receipts representing securities of the Underlying Index) and may invest up to 10% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, as well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

considered to be issued by members of any industry.

Summary of Principal Risks

S-3

instruments that have lower trading volumes.

Participants or issuers of securities in which the Fund invests.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund

S-4

has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which

the Fund’s shares trade is open, there are likely to be deviations between the current price of such an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

Natural Resources Industry Risk. The value of securities issued by companies in the natural resources industry may decline for many reasons, including changes in commodity prices or government regulation, environmental damage claims, changes in exchange rates or depletion of natural resources.

S-5

or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and BFA seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Real Estate Investment Risk. The Fund may invest in companies that invest in real estate (“Real Estate Companies”), such as REITs or real estate holding companies, which expose investors in the Fund to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which Real Estate Companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments, and characterized by intense competition and periodic overbuilding. Many Real Estate Companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially magnify the Fund’s losses. Rising interest rates could result in higher costs of capital for Real Estate Companies, which could negatively affect a Real Estate Company's ability to meet its payment obligations or its financing activity, and could decrease the market prices for REITs and for properties held by such REITs.

the Fund is specifically exposed to European Economic Risk and North American Economic Risk.

Security Risk. Some countries and regions in which the Fund invests have

S-6

experienced security concerns, such as terrorism and strained international relations. Incidents involving a country's or region's security may cause uncertainty in its markets and may adversely affect its economy and the Fund's investments.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Timber and Forestry Industry Risk. The timber and forestry industry is affected by changes in international economic conditions, interest rates, weather cycles, changing demographics, environmental conditions and government regulations, among other factors.

Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. INDEX ETFs THAT TRACK INDICES WITH SIGNIFICANT WEIGHT IN EMERGING MARKETS ISSUERS MAY EXPERIENCE HIGHER TRACKING ERROR THAN OTHER INDEX ETFs THAT DO NOT TRACK SUCH INDICES.

Purchase and Sale of Fund Shares

The Fund is an ETF. Individual shares of the Fund are listed on a national securities exchange. Most investors will buy and sell shares of the Fund through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than at NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 60,000 shares or multiples thereof (“Creation Units”) to Authorized Participants who have entered into agreements with the Fund's distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Responses to financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest, may limit future growth and economic recovery or may have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. In a referendum held on June 23, 2016, the U.K. resolved to leave the EU. The referendum may introduce significant uncertainties and instability in the financial markets as the U.K. negotiates its exit from the EU. Although the precise timeframe for the U.K.’s withdrawal is uncertain, on March 29, 2017, the U.K. initiated the withdrawal process by sending a formal notice of the country’s intention to withdraw from the EU. An agreement has been reached between the U.K. and the EU to continue negotiations on the U.K.’s exit from the EU. The outcome of negotiations remain uncertain.

Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

Market Trading Risk

discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Materials Sector Risk. Companies in the materials sector may be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical advances, labor relations and government regulations, among other factors. The containers and packaging industry, in particular, is susceptible to imbalances of supply and demand, and companies may incur significant environmental remediation costs in complying with federal, state and local environmental laws. Companies in the materials sector are also at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

Natural Resources Industry Risk. The profitability of companies in the natural resources industry can be affected by worldwide energy prices, limits on exploration, and production spending. Companies in the natural resources industry are affected by government regulation, world events and economic conditions. Companies in the natural resources industry are at risk for environmental damage claims. Companies in the natural resources industry could be adversely affected by commodity price volatility, changes in exchange rates, imposition of import controls and increased competition. Companies in the natural resources industry may be adversely affected by depletion of natural resources, technological developments, and labor relations.

■	Lower levels of liquidity and market efficiency;
■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;
■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements; and

■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the U.S.

these measures do not address every possible risk and may be inadequate to address significant operational risks.

Real Estate Investment Risk. The Fund may invest in Real Estate Companies, such as REITs or real estate holding companies, which expose investors to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which Real Estate Companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments and is characterized by intense competition and periodic overbuilding. Many Real Estate Companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially increase the Fund’s losses. Rising interest rates could result in higher costs of capital for Real Estate Companies, which could negatively affect a Real Estate Company's ability to meet its payment obligations or its financing activity, and could decrease the market prices for REITs and for properties held by such REITs. In addition, to the extent a Real Estate Company has its own expenses, the Fund (and indirectly, its shareholders) will bear its proportionate share of such expenses.

Equity REITs Risk. Certain REITs may make direct investments in real estate. These REITs are often referred to as “Equity REITs.” Equity REITs invest primarily in real properties and may earn rental income from leasing those properties. Equity REITs may also realize gains or losses from the sale of properties. Equity REITs will be affected by conditions in the real estate rental market and by changes in the value of the properties they own. A decline in rental income may occur because of extended vacancies, limitations on rents, the failure to collect rents, increased competition from other properties or poor management. Equity REITs also can be affected by rising interest rates. Rising interest rates may cause investors to demand a high annual yield from future distributions that, in turn, could decrease the market prices for such REITs and for the properties held by such REITs. In addition, rising interest rates also increase the costs of obtaining financing for real estate projects. Because many real estate projects are dependent upon receiving financing, this could cause the value of the Equity REITs in which the Fund invests to decline.

Repayment Risk. The prices of Real Estate Company securities may drop because of the failure of borrowers to repay their loans, poor management, or the inability to

obtain financing either on favorable terms or at all. If the properties in which Real Estate Companies invest do not generate sufficient income to meet operating expenses, including, where applicable, debt service, ground lease payments, tenant improvements, third-party leasing commissions and other capital expenditures, the income and ability of the Real Estate Companies to make payments of interest and principal on their loans will be adversely affected.

increased internal unrest and discord. If this trend were to continue, it may have an adverse impact on the U.S. economy and many of the issuers in which the Fund invests.

Timber and Forestry Industry Risk. The timber and forestry industry is highly cyclical and the market value of companies engaged in the ownership, management or upstream supply chain of forests and timberlands is strongly affected by changes in international economic conditions, interest rates, weather cycles, changing demographics, environmental conditions and government regulations, among other factors. For example, the volume and value of timber that can be harvested from timberlands is limited by natural disasters, fire, volcanic eruptions, insect infestation, disease, ice storms, wind storms, flooding and other events. Climate conditions could intensify the effects of any of these factors. Many companies in the timber and forestry industry do not insure against damages to their timberlands. Companies in this

industry are also subject to stringent federal, state and local environmental, health and safety laws and regulations.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia. Any adverse event in the Asian markets may have a significant adverse effect on some or all of the economies of the countries in which the Fund invests. Many Asian countries are subject to political risk, including political instability, corruption and regional conflict with neighboring countries. North Korea and South Korea each have substantial military capabilities, and historical tensions between the two countries present the risk of war. Escalated tensions involving the two countries and any outbreak of hostilities between the two countries, or even the threat of an outbreak of hostilities, could have a severe adverse effect on the entire Asian region. In addition, many Asian countries are subject to social and labor risks associated with demands for improved political, economic and social conditions. These risks, among others, may adversely affect the value of the Fund’s investments.

A “significant event” is deemed to occur if BFA determines, in its reasonable business judgment prior to or at the time of pricing the Fund’s assets or liabilities, that the event is likely to cause a material change to the closing market price of one or more assets or liabilities held by the Fund. Non-U.S. securities whose values are affected by volatility that occurs in the local markets or in related or highly correlated assets (e.g., American Depositary Receipts, Global Depositary Receipts or substantially identical ETFs) on a trading day after the close of non-U.S. securities markets may be fair valued.

Dividends and Distributions

Other foreign entities may need to report the name, address, and taxpayer identification number of each substantial U.S. owner or provide certifications of no substantial U.S. ownership unless certain exceptions apply.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 60,000 shares or multiples thereof. Each “creator” or authorized participant (an “Authorized Participant”) has entered into an agreement with the Fund's distributor, BlackRock Investments, LLC (the “Distributor”), an affiliate of BFA.

The standard creation and redemption transaction fees are charged on each Creation Unit created or redeemed, as applicable, by an Authorized Participant on the day of the transaction. The standard transaction fee is generally fixed at the amount shown in the table regardless of the number of Creation Units being purchased or redeemed, but may be reduced by the Fund if transfer and processing expenses associated with the creation or redemption are anticipated to be lower than the stated fee. If a purchase or redemption consists solely or partially of cash, the Authorized Participant may also be required to pay an additional transaction charge (up to the maximum amounts shown in the table below) to cover brokerage and certain other costs related to a creation or redemption transaction. Investors who use the services of a broker or other financial intermediary to acquire or dispose of Fund shares may pay fees for such services.

Summary of Principal Risks

S-3

Electric Utilities Sector Risk. Companies in the electric utilities sector may be adversely affected by increases in fuel and other operating costs, high interest costs on borrowings needed for capital construction programs, costs associated with compliance with environmental and safety regulations, and changes in the regulatory climate. The electric utilities sector is subject to significant government regulation and oversight. In particular, the construction and operation of nuclear power facilities

are subject to strict scrutiny by, and evolving regulations of, the Nuclear Regulatory Commission and state agencies which have comparable jurisdiction. A number of states are considering or have enacted deregulation proposals. Deregulation may subject electric utilities sector companies to greater competition, which may result in lower revenue, lower credit ratings, increased default risk, and lower electric utility security prices.

S-4

index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

S-5

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

S-6

Valuation Risk. The price the Fund could receive upon the sale of a security

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Electric Utilities Sector Risk. The electric utility industry consists of companies that are engaged principally in the generation, transmission and sale of electric energy, although many also provide other energy-related services. In the past, electric utility companies, in general, have been favorably affected by lower fuel and financing costs and the full or near completion of major construction programs. In addition, many of these companies have generated cash flows in excess of current operating expenses and construction expenditures, permitting some degree of diversification into unregulated businesses. Some electric utilities have also taken advantage of the right to sell power outside of their traditional geographic areas. Electric utility companies have historically been subject to the risks associated with increases in fuel and other operating costs, high interest costs on borrowings needed for capital construction programs, costs associated with compliance with environmental and safety regulations and changes in the regulatory climate. As interest rates declined, many utilities refinanced high cost debt and in doing so improved their fixed charges coverage. Regulators, however, lowered allowed rates of return as interest rates declined and thereby caused the benefits of the rate declines to be shared wholly or in part with customers. In a period of rising interest rates, the allowed rates of return may not keep pace with the utilities’ increased costs. The construction and operation of nuclear power facilities are subject to strict scrutiny by, and evolving regulations of, the Nuclear Regulatory Commission and state agencies which have comparable jurisdiction. Strict scrutiny might result in higher operating costs and higher capital expenditures, with the risk that the regulators may disallow inclusion of these costs in rate authorizations or the risk that a company may not be permitted to operate or complete construction of a facility. In addition, operators of nuclear power plants may be subject to significant costs for disposal of nuclear fuel and for decommissioning such plants.

The rating agencies look closely at the business profile of utilities. Ratings for companies are expected to be impacted to a greater extent in the future by the division of their asset base. Electric utility companies that focus more on the generation of electricity may be assigned less favorable ratings as this business is expected to be competitive and the least regulated. On the other hand, companies that focus on transmission and distribution, which is expected to be the least competitive and the more regulated part of the business, may see higher ratings given the greater predictability of cash flow.

A number of states are considering or have enacted deregulation proposals. The introduction of competition into the industry as a result of such deregulation has at times resulted in lower revenue, lower credit ratings, increased default risk, and lower electric utility security prices. Such increased competition may also cause long-term

contracts, which electric utilities previously entered into to buy power, to become “stranded assets” which have no economic value. Any loss associated with such contracts must be absorbed by ratepayers and investors. In addition, some electric utilities have acquired electric utilities overseas to diversify, enhance earnings and gain experience in operating in a deregulated environment. In some instances, such acquisitions have involved significant borrowings, which have burdened the acquirer’s balance sheet. There is no assurance that current deregulation proposals will be adopted. However, deregulation in any form could significantly impact the electric utilities industry.

Responses to financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest, may limit future growth and economic recovery or may have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. In a referendum held on June 23, 2016, the U.K. resolved to leave the EU. The referendum may introduce significant uncertainties and instability in the financial markets as the U.K. negotiates its exit from the EU. Although the precise timeframe for the U.K.’s withdrawal is uncertain, on March 29, 2017, the U.K. initiated the withdrawal process by sending a formal notice of the country’s intention to withdraw from the EU. An agreement has

been reached between the U.K. and the EU to continue negotiations on the U.K.’s exit from the EU. The outcome of negotiations remain uncertain.

Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

additional ad hoc rebalances carried out by the Index Provider or its agents to the Underlying Index may increase the costs to and the tracking error risk of the Fund.

Market Trading Risk

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

■	Lower levels of liquidity and market efficiency;
■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;
■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;

■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements; and

■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the U.S.

rise in the U.S. public debt level or U.S. austerity measures may adversely affect U.S. economic growth and the securities to which the Fund has exposure.

Utilities Sector Risk. Companies in the utilities sector may be adversely affected by changes in exchange rates, domestic and international competition, and governmental limitations on rates charged to customers. The value of regulated utility debt securities (and, to a lesser extent, equity securities) tends to have an inverse relationship to the

movement of interest rates. Deregulation may subject utility companies to greater competition and may adversely affect their profitability. As deregulation allows utility companies to diversify outside of their original geographic regions and their traditional lines of business, utility companies may engage in riskier ventures. In addition, deregulation may eliminate restrictions on the profits of certain utility companies, but may also subject these companies to greater risk of loss. Companies in the utilities industry may have difficulty obtaining an adequate return on invested capital, raising capital, or financing large construction projects during periods of inflation or unsettled capital markets; face restrictions on operations and increased cost and delays attributable to environmental considerations and regulation; find that existing plants, equipment or products have been rendered obsolete by technological innovations; or be subject to increased costs because of the scarcity of certain fuels or the effects of man-made or natural disasters. Existing and future regulations or legislation may make it difficult for utility companies to operate profitably. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. In certain countries, regulatory authorities may also restrict utility companies’ access to new markets, thereby diminishing these companies’ long-term prospects. There is no assurance that regulatory authorities will grant rate increases in the future or that such increases will be adequate to permit the payment of dividends on stocks issued by a utility company. Energy conservation and changes in climate policy may also have a significant adverse impact on the revenues and expenses of utility companies.

iShares^®

On December 5, 2011, in connection with the establishment of the iShares iBonds Sep 2018 Term Muni Bond ETF (the “Fund), the Board of Trustees of the Trust approved the planned liquidation, dissolution and termination of the Fund. As a result, the last day of trading in the Fund on NYSE Arca, Inc. (“NYSE Arca”) will be September 4, 2018. NYSE Arca will suspend trading in the Fund before the open of trading on September 5, 2018 and shares of the Fund will no longer be available for new investments as of this date. Proceeds of the liquidation are currently scheduled to be sent to shareholders on September 10, 2018. The Fund’s final net asset value, as calculated on September 4, 2018, will include any costs associated with the liquidation expected to be borne by the Fund.

Because shares of the Fund will not be traded on NYSE Arca during the period between September 5, 2018 and September 10, 2018, we cannot assure you that there will be a trading market for your shares. Further, during this period, the Fund will be in the process of closing down and liquidating its portfolio, which will result in the Fund not being able to track its Underlying Index, and the Fund will hold cash and securities that may not be consistent with its investment objective and strategies. After September 4, 2018, shareholders that remain invested in the Fund will receive the entire amount of their pro rata share of the liquidation proceeds on or about September 10, 2018, subject to their brokerage firm’s processes.

Shareholders may sell their holdings of the Fund prior to September 5, 2018 and may incur the usual and customary brokerage commissions associated with the sale of Fund shares. At the time the liquidation of the Fund is complete, shares of the Fund will be individually redeemed. If you still hold shares of the Fund on September 10, 2018, the Fund will automatically redeem your shares for cash based on the net asset value as of the close of business on September 4, 2018, which will include any dividends or distributions calculated as of that date.

If you are subject to federal income tax, the liquidation of the Fund will result in one or more taxable events for you. A sale or exchange of Fund shares prior to the liquidation will generally give rise to a capital gain or loss to you for federal income tax purposes. In connection with the liquidation, the Fund may declare tax exempt or taxable distributions of its investment income and/or taxable distributions of its net capital gain. Any liquidation proceeds paid to you should generally be treated as received by you in exchange for your shares and will therefore generally give rise to a capital gain or loss depending on your tax basis. Please consult your personal tax advisor about the potential tax consequences.

If you have additional questions, please call 1-800-iShares (1-800-474-2737).

iSHARES^® iBONDS^® SEP 2018 TERM MUNI BOND ETF

Ticker: IBMG

Stock Exchange: NYSE Arca

Investment Objective

The iShares iBonds Sep 2018 Term Muni Bond ETF (the “Fund”) seeks to track the investment results of an index composed of investment-grade U.S. municipal bonds maturing after May 31 and before September 2, 2018.

Fees and Expenses

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

Annual Fund Operating Expenses (ongoing expenses that you pay each year as a percentage of the value of your investments)
Management Fees	Distribution and Service (12b-1) Fees	Other Expenses	Total Annual Fund Operating Expenses
0.18%	None	None	0.18%

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. Fund expenses are calculated only through September 1, 2018 because the Fund is scheduled to cease operations and liquidate on or around that date. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P AMT-Free Municipal Series 2018 Index^TM (the “Underlying Index”), which measures the performance of investment-grade (as determined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”)), non-callable U.S. municipal bonds maturing in 2018. As of March 31, 2018, there were 4,259 issues in the Underlying Index.

The Underlying Index includes municipal bonds primarily from issuers that are state or local governments or agencies such that the interest on the bonds is exempt from U.S. federal income taxes. Each bond must have a rating of at least BBB- by S&P Global Ratings (“S&P”), Baa3 by Moody’s Investors Service, Inc. (“Moody's”), or BBB- by Fitch Ratings, Inc. and must have a minimum maturity par amount of $2 million to be eligible for inclusion in the Underlying Index. To remain in the Underlying Index, bonds must maintain a minimum par amount greater than or equal to $2 million, and must not be subject to the federal alternative minimum tax (“AMT”) as of each rebalancing date. All bonds in the Underlying Index will mature after May 31 and before September 2 of the year referenced in the name of the

Underlying Index. When a bond in the Underlying Index matures or is pre-refunded, the bond does not accrue interest past the maturity or pre-refunded date. An amount representing its value at the time of maturity or pre-refunding will be included in the Underlying Index throughout the remaining life of the Underlying Index, and any such amount will be assumed to earn a rate equal to the tax-exempt return of cash and cash equivalents. The Underlying Index is a market value weighted index and is rebalanced after the market close on the last business day of each month.

The Fund is a series of the iShares iBonds^® fixed maturity series of bond exchange-traded funds (“ETFs”) sponsored by BlackRock, Inc. (“BlackRock”). The iBonds^® fixed maturity series do not invest in U.S. savings bonds or other U.S. government bonds and are not designed to provide protection against inflation.

underlying index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability, duration, maturity, credit ratings and yield) and liquidity measures similar to those of an applicable underlying index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally will invest at least 90% of its assets in the component securities of the Underlying Index, except during the last months of the Fund's operations, as described below, and may invest up to 10% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates (“BlackRock Cash Funds”), as well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. From time to time when conditions warrant, however, the Fund may invest at least 80% of its assets in the component securities of the Underlying Index and may invest up to 20% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of BlackRock Cash Funds, as well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. The Fund will generally hold municipal bond securities issued by state and local municipalities whose interest payments are exempt from U.S. federal income tax, the federal AMT and the federal Medicare contribution tax of 3.8% on “net investment income,” including dividends, interest and capital gains. In the last months of operation, as the bonds held by the Fund mature, the proceeds will not be reinvested in bonds but instead will be held in cash and cash equivalents, including, without

limitation, money market funds affiliated with BFA, AMT-free tax-exempt municipal notes, variable rate demand notes and obligations, tender option bonds and municipal commercial paper. These cash equivalents may not be included in the Underlying Index. By September 1, 2018, the Underlying Index is expected to consist entirely of cash earned in this manner. Around the same time, the Fund will wind up and terminate, and its net assets will be distributed to then-current shareholders. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities), repurchase agreements collateralized by U.S. government securities, and securities of state or municipal governments and their political subdivisions are not considered to be issued by members of any industry.

Summary of Principal Risks

S-3

trading price, yield, total return and ability to meet its investment objective.

Concentration Risk. The Fund may be susceptible to loss due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular state, region, municipality, market, project type, industry, group of industries, or asset class.

Credit Risk. Debt issuers and other counterparties may be unable or unwilling to make timely interest and/or principal payments when due or otherwise honor their obligations. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also adversely affect the value of the Fund’s investment in that issuer. The degree of credit risk depends on an issuer’s or

counterparty’s financial condition and on the terms of an obligation.

Declining Yield Risk. During the final three months prior to the Fund's planned termination date, its yield will generally tend to move toward prevailing money market rates, and may be lower than the yields of the bonds previously held by the Fund and lower than prevailing yields for bonds in the market.

S-4

existence it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund's portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in municipal bonds. If the amount you receive as liquidation proceeds upon the Fund's termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Income Risk. The Fund's income may decline when interest rates fall. This decline can occur because the Fund may subsequently invest in lower-yielding bonds as bonds in its portfolio mature or are near maturity, bonds in the Underlying Index are substituted with cash and cash equivalents, or the Fund otherwise needs to purchase additional bonds.

Interest Rate Risk. An increase in interest rates may cause the value of securities held by the Fund to decline, may lead to heightened volatility in the fixed-income markets and may

adversely affect the liquidity of certain fixed-income investments. The historically low interest rate environment, together with recent modest rate increases, heightens the risks associated with rising interest rates.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. The Fund invests in municipal bonds of issuers that are primarily state or local governments or agencies. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Liquidity Risk. Liquidity risk exists when particular investments are difficult to purchase or sell. This can reduce the Fund's returns because the Fund may be unable to transact at advantageous times or prices. The Fund invests a significant portion of its portfolio in municipal securities, which may be less liquid than comparable taxable bonds.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Municipal Securities Risk. Municipal securities can be significantly affected

S-5

by political or economic changes, including changes made in the law after issuance of the securities, as well as uncertainties in the municipal market related to taxation, legislative changes or the rights of municipal security holders, including in connection with an issuer insolvency. Municipal securities backed by current or anticipated revenues from a specific project or specific assets can be negatively affected by the inability to collect revenues from the project or the assets.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Tax Risk. There is no guarantee that the Fund's income will be exempt from U.S.

federal income taxes, the federal AMT or the federal Medicare contribution tax of 3.8% on “net investment income.”

Valuation Risk. The sale price the Fund could receive for a security may differ from the Fund's valuation of the security or asset and from the value used by the Underlying Index, particularly for securities or assets that trade in low volume or volatile markets or that are valued using a fair value methodology. Because the bond market may be open on days or during time periods when the Fund does not price its shares, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares.

More Information About the Fund

The Fund will wind up and terminate on or about September 1, 2018. Upon its termination, the Fund will distribute substantially all of its net assets, after making appropriate provision for any liabilities of the Fund, to then-current shareholders pursuant to a plan of liquidation. In the final months of the Fund's operations, as the bonds it holds mature, its portfolio will transition to cash and cash-like instruments, including without limitation AMT-free tax-exempt municipal notes, variable rate demand notes and obligations, tender option bonds and municipal commercial paper. By September 1, 2018, the Underlying Index is expected to consist almost entirely of cash earned in this manner. As the Fund approaches its termination date, its holdings of money market or similar funds may increase, causing the Fund to incur the fees and expenses associated with investing in these funds. In accordance with the Trust's current Amended and Restated Agreement and Declaration of Trust, the Fund will terminate on or about the date noted above as approved by a majority of the Trust's Board of Trustees (the “Board”) without requiring additional approval by Fund shareholders. The Board may extend the termination date if a majority of the Board determines the extension to be in the best interest of the Fund.

actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from the Fund's use of representative sampling or from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index. From time to time, the Index Provider may make changes to the methodology or other adjustments to the Underlying Index. Unless otherwise determined by BFA, any such change or adjustment will be reflected in the calculation of the Underlying Index performance on a going-forward basis after the effective date of such change or adjustment. Therefore, the Underlying Index performance shown for periods prior to the effective date of any such change or adjustment will generally not be recalculated or restated to reflect such change or adjustment.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Asset Class Risk. The securities and other assets in the Underlying Index or in the Fund’s portfolio may underperform in comparison to other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities, currencies and indexes may experience cycles of outperformance and underperformance in comparison to the general financial markets. This may cause the Fund to underperform other investment vehicles that invest in different asset classes.

Concentration Risk. The Fund may be more susceptible to an increased risk of loss due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of issuers in a particular state, region, municipality, market, project type, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences than the market as a whole.

Credit Risk. Credit risk is the risk that the issuer or guarantor of a debt instrument or the counterparty to a derivatives contract, repurchase agreement or loan of portfolio securities will be unable or unwilling to make its timely interest and/or principal payments when due or otherwise honor its obligations. There are varying degrees of credit risk, depending on an issuer’s or counterparty’s financial condition and on the terms of an obligation, which may be reflected in the issuer’s or counterparty’s credit rating. There is the chance that the Fund’s portfolio holdings will have their credit ratings downgraded or will default (i.e., fail to make scheduled interest or principal payments), or that the market’s perception of an issuer’s creditworthiness may worsen, potentially reducing the Fund’s income level or share price, which may adversely affect the value of the Fund.

Authorized Participants or the issuers of securities in which the Fund invests, have the ability to cause disruptions and impact business operations, potentially resulting in: financial losses, interference with the Fund’s ability to calculate its NAV, disclosure of confidential trading information, impediments to trading, submission of erroneous trades or erroneous creation or redemption orders, the inability of the Fund or its service providers to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. In addition, cyber attacks may render records of Fund assets and transactions, shareholder ownership of Fund shares, and other data integral to the functioning of the Fund inaccessible or inaccurate or incomplete. Substantial costs may be incurred by the Fund in order to resolve or prevent cyber incidents in the future. While the Fund has established business continuity plans in the event of, and risk management systems to prevent, such cyber attacks, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified and that prevention and remediation efforts will not be successful. Furthermore, the Fund cannot control the cyber security plans and systems put in place by service providers to the Fund, issuers in which the Fund invests, the Index Provider, market makers or Authorized Participants. The Fund and its shareholders could be negatively impacted as a result.

Declining Yield Risk. During the three months prior to the Fund's planned termination date, the bonds held by the Fund will mature and the Fund’s portfolio will convert to cash or cash equivalents. During these final three months, the Fund’s yield will generally tend to move toward prevailing money market rates, and may be lower than the yields of the bonds previously held by the Fund and lower than prevailing yields for bonds in the market.

Fluctuation of Yield and Liquidation Amount Risk. The Fund, unlike a direct investment in a municipal bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. It is expected that an investment in the Fund, if held through maturity, will produce aggregate returns comparable to a direct investment in a group of municipal bonds of similar credit quality and maturity to those held by the Fund, but unlike a direct investment in municipal bonds, the breakdown of returns between Fund distributions and liquidation proceeds will not be predictable at the time of your investment. The Fund may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund's portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The breakdown between Fund distribution payments and the amount of liquidation proceeds may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in municipal bonds. If the amount you receive as liquidation proceeds upon the Fund's termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes. In addition, the yield on your investment (i.e., the return on your purchase price) may be lower (or higher) than the Fund's published yields, which are based on the Fund's NAV.

Income Risk. The Fund’s income may decline when interest rates fall. This decline can occur because the Fund may subsequently invest in lower-yielding bonds as bonds in

its portfolio mature, bonds in the Underlying Index are substituted with cash and cash equivalents, or the Fund otherwise needs to purchase additional bonds. The Index Provider’s substitution of bonds in the Underlying Index may occur, for example, when the time to maturity for the bond no longer matches the Underlying Index’s stated maturity guidelines.

Interest Rate Risk. As interest rates rise, the value of a fixed-income security held by the Fund is likely to decrease. Securities with longer durations tend to be more sensitive to interest rate changes, usually making their prices more volatile than those of securities with shorter durations. To the extent the Fund invests a substantial portion of its assets in fixed-income securities with longer-term durations, which is expected to occur to a greater degree earlier in the life of the Fund, rising interest rates may cause the value of the Fund’s investments to decline significantly, which

may adversely affect the value of the Fund. An increase in interest rates may lead to heightened volatility in the fixed-income markets and adversely affect the liquidity of certain fixed-income investments. In addition, decreases in fixed-income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed-income markets.

The historically low interest rate environment was created in part by the U.S. Board of Governors of the Federal Reserve System (the “Fed”) and certain foreign central banks keeping the federal funds and equivalent foreign rates at or near zero percent. The Fed recently raised its benchmark interest rate several times as the U.S. labor market strengthened and economic activity accelerated. The Fed indicated that it expects its accommodative monetary policy stance to support strong labor market conditions and a sustained return to target inflation, which increases the likelihood of rising interest rates in the future. Fed policy going forward is less clear given recent changes in Fed leadership. Because the Fund holds a portfolio of securities set to mature at approximately the same time, the Fund generally will have greater exposure to interest rate risk earlier in its life than closer to its termination date.

Issuer Risk. Changes in the financial condition of an issuer or counterparty, changes in specific economic or political conditions that affect a particular type of security or issuer, and changes in general economic or political conditions can affect a security’s or instrument’s credit quality or value. An issuer may also be subject to risks associated with the countries, states and regions in which the issuer resides, invests, sells products, or otherwise conducts operations.

Liquidity Risk. Liquidity risk exists when particular investments are difficult to purchase or sell. To the extent the Fund invests in illiquid securities or securities that become less liquid, such investments may have a negative effect on the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price. To the extent that the Fund invests in securities with substantial market and/or credit risk, the Fund will tend to have increased exposure to liquidity risk. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed-income securities or the lack of an active market for such securities. Liquid investments may become illiquid or less liquid, particularly during periods of market turmoil or economic uncertainty. Illiquid and relatively less liquid investments may be harder to value. Although the Fund primarily seeks to redeem shares of the Fund on an in-kind basis, if the Fund is forced to sell underlying investments at reduced prices or under unfavorable conditions to meet redemption requests or other cash needs, the Fund may suffer a loss. This risk may be magnified in a rising interest rate environment or other circumstances where redemptions from the Fund may be greater than normal. Other market participants may be attempting to liquidate fixed-income holdings at the same time as the Fund, causing increased supply of the Fund's underlying investments in the market and contributing to liquidity risk and downward pricing pressure. There can be no assurance that a security that is deemed to be liquid when purchased will continue to be liquid for as long as it is held by the Fund.

The market for municipal bonds may be less liquid than for taxable bonds. There may also be less information available on the financial condition of issuers of municipal

securities than on public corporations. This means that it may be harder to buy and sell municipal securities, especially on short notice, and municipal securities may be more difficult for the Fund to value accurately than securities of public corporations. Since the Fund invests a significant portion of its portfolio in municipal securities, the Fund’s portfolio may have greater exposure to liquidity risk than a fund that invests in comparable non-municipal securities.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. Market risk arises mainly from uncertainty about future values of financial instruments and may be influenced by price, currency and interest rate movements. It represents the potential loss the Fund may suffer through holding financial instruments in the face of market movements or uncertainty. The value of a security or other asset may decline due to changes in general market conditions, economic trends or events that are not specifically related to the issuer of the security or other asset, or factors that affect a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class. During a general market downturn, multiple asset classes may be negatively affected. Fixed-income securities with short-term maturities are generally less sensitive to such changes than are fixed-income securities with longer-term maturities. Changes in market conditions and interest rates generally do not have the same impact on all types of securities and instruments. In addition, since many municipal securities are issued to finance similar projects, such as those relating to education, health care, housing, transportation, utilities, and water and sewer, conditions in these industries can affect the overall municipal market.

Market Trading Risk

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below the Fund’s most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Fund's shares fluctuates continuously throughout trading hours based on both market supply of and demand for Fund shares and the underlying value of the Fund's portfolio holdings or NAV. As a result, the trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility, including during periods of significant redemption requests or other unusual market conditions. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV, BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long term (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs). While the creation/redemption feature is designed to make it more likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund's NAV due to timing reasons, supply and demand imbalances and other factors. In addition, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants, or other market participants, and during periods of significant market volatility, may result in trading prices for shares of the Fund that differ significantly from its NAV. Authorized Participants may be less willing to create or redeem Fund shares if there is a lack of an active market for such shares or its underlying investments, which may contribute to the Fund’s shares trading at a premium or discount to NAV.

volume and market liquidity, is generally narrower if the Fund has more trading volume and market liquidity and wider if the Fund has less trading volume and market liquidity. In addition, increased market volatility may cause wider spreads. There may also be regulatory and other charges that are incurred as a result of trading activity. Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments through a brokerage account.

Municipal Securities Risk. Municipal securities are subject to the risk that litigation, legislation or other political events, local business or economic conditions, credit rating downgrades, or the bankruptcy of the issuer could have a significant effect on an issuer’s ability to make payments of principal and/or interest or otherwise affect the value of such securities.

Municipal securities can be significantly affected by political or economic changes, including changes made in the law after issuance of the securities, as well as uncertainties in the municipal market related to taxation, legislative changes or the rights of municipal security holders, including in connection with an issuer insolvency. Because many municipal securities are issued to finance similar projects, such as those related to education, health care, housing, transportation, utilities, and water and sewer, conditions in these sectors can affect the overall municipal market. In addition, changes in the financial condition of an individual municipal insurer can affect the overall municipal market.

Municipal securities backed by current or anticipated revenues from a specific project or specific assets can be negatively affected by the discontinuance of the tax benefits supporting the project or assets or the inability to collect revenues from the project or the assets. Municipal securities may be less liquid than taxable bonds, and there may be less publicly available information on the financial condition of municipal security issuers than for issuers of other securities. The Fund and BFA will rely on the opinion of issuers’ bond counsel on the tax-exempt status of interest on municipal bonds. Neither the Fund nor BFA will independently review the bases for those tax opinions, which may ultimately be determined to be incorrect, potentially resulting in the Fund and its shareholders being subject to substantial tax liabilities.

Tax Risk. There is no guarantee that the Fund’s income will be exempt from U.S. federal income taxes, the federal AMT or the federal Medicare contribution tax of 3.8% on “net investment income.” The Index Provider relies on the bond issuer’s prospectus disclosure of the opinion from its counsel as to the tax-exempt status of the investment. Similarly, for municipal bonds not represented in the Underlying Index, BFA relies on prospectus disclosure of the tax opinion from the bond issuer’s counsel. Neither BFA nor the Fund guarantees that these opinions are correct, and there is no assurance that the U.S. Internal Revenue Service (“IRS”) will agree with the bond issuer’s counsel’s tax opinion. Issuers or other parties generally enter into covenants requiring continuing compliance with U.S. federal tax requirements to preserve the tax-free status of interest payments over the life of the security. If at any time the covenants are not complied with, or if the IRS otherwise determines that the issuer did not comply with relevant tax requirements, interest payments from a security could become federally taxable, possibly retroactively to the date the security was issued, and the security could decline significantly in value. For municipal bonds not included in the Underlying Index, BFA will generally seek to obtain bonds that pay interest that is exempt from U.S. federal income taxes, the federal AMT and the federal Medicare contribution tax. The interest on any money market instruments or other cash equivalents held by the Fund may be subject to the federal AMT or the federal Medicare contribution tax.

Events occurring after the date of issuance of a municipal bond or after the Fund’s acquisition of a municipal bond may result in a determination that interest on that bond is includible in gross income for U.S. federal income tax, federal AMT or federal Medicare contribution tax purposes retroactively to its date of issuance. Such a determination may cause a portion of prior distributions by the Fund to its shareholders to be taxable to those shareholders in the year of receipt. U.S. federal or state changes in income, federal AMT or federal Medicare contribution tax rates or in the tax treatment of municipal bonds may make municipal bonds less attractive as investments and cause them to lose value. If the IRS determines an issuer of a municipal security has not complied with applicable tax requirements, interest from

the security could become taxable, even retroactively, and the securities could decline significantly in value.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

School District Investment Risk. School districts rely, in part, on funding appropriations from, among others, the federal government and state governments. As a result, municipal securities issued by school districts may be adversely affected by political and economic changes at the state or federal levels, such as decreased tax or other revenues, spending reductions or changes in appropriations. Municipal securities that are issued to finance a particular school district project often depend on revenues from that project to make principal and interest payments. Adverse conditions and developments affecting a particular project can result in lower revenues to the issuer of the municipal securities. Investors in these securities, similar to investors in

municipal securities generally, face heightened risk of loss upon insolvency of the school district issuers because there is often no ready source of funding to pay the bonds other than the local tax base, which a bankruptcy court or administrator does not control.

Transportation Infrastructure Industry Risk. The transportation infrastructure industry may be adversely affected by economic changes, increases in fuel and operating costs, labor relations, insurance costs, and, in certain countries, significant government regulation and oversight. Municipal securities that are issued to finance a particular transportation project (e.g., toll roads) often depend on revenues from that project to make principal and interest payments. Adverse conditions and developments affecting a particular project can result in lower revenues to the issuer of the municipal securities. Other risk factors that may affect the transportation infrastructure industry include the risk of increases in fuel and other operating costs and the effects of regulatory changes or other government decisions.

Utilities Sector Risk. Deregulation may subject utility companies to greater competition and may adversely affect their profitability. As deregulation allows utility companies to diversify outside of their original geographic regions and their traditional lines of business, utility companies may engage in riskier ventures. In addition, deregulation may eliminate restrictions on the profits of certain utility companies, but may also subject these companies to greater risk of loss. Companies in the utilities industry may have difficulty obtaining an adequate return on invested capital, raising capital, or financing large construction projects during periods of inflation or unsettled capital markets; face restrictions on operations and increased cost and delays attributable to environmental considerations and regulation; find that existing plants, equipment or products have been rendered obsolete by technological innovations; or be subject to increased costs because of the scarcity of certain fuels or the effects of man-made or natural disasters. Existing and future regulations or legislation may make it difficult for utility companies to operate profitably. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. There is no assurance that regulatory authorities will grant rate increases in the future or that such increases will be adequate to permit the payment of coupon payments on bonds issued by or in respect to such companies. Energy conservation and changes in climate policy may also have a significant adverse impact on the revenues and expenses of utility companies.

Portfolio Holdings Information

Management

For its investment advisory services to the Fund, BFA is paid a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.18%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is an indirect wholly-owned subsidiary of BlackRock. As of June 30, 2018, BFA and its affiliates provided investment advisory services for assets in excess of $6.29 trillion. BFA and its affiliates trade and invest for their own accounts in the actual securities and types of securities in which the Fund may also invest, which may affect the price of such securities.

A discussion regarding the basis for the approval by the Board of the Investment Advisory Agreement with BFA is available in the Fund's semi-annual report for the period ended September 30.

Portfolio Managers. James Mauro and Scott Radell are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his portfolio management team that have more limited responsibilities.

James Mauro has been employed by BFA as a portfolio manager since 2011. Prior to that, Mr. Mauro was a Vice President at State Street Global Advisors. Mr. Mauro has been a Portfolio Manager of the Fund since 2013.

Scott Radell has been employed by BFA as a portfolio manager since 2004. Mr. Radell was a credit strategist from 2003 to 2004 and became a portfolio manager at Barclays Global Fund Advisors in 2004. Mr. Radell has been a Portfolio Manager of the Fund since 2013.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

BFA or an Affiliate may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and

The Fund's activities may be limited because of regulatory restrictions applicable to one or more Affiliates and/or their internal policies designed to comply with such restrictions.

Shareholder Information

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as the supply of and demand for ETF shares and underlying securities held by the Fund, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout each trading day by the national securities exchange on which the Fund's shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities or other assets and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities or other assets held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund's NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and price quotations obtained from broker-dealers and other market intermediaries that may trade in the portfolio securities or other assets held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the U.S. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

The Fund values fixed-income portfolio securities using last available bid prices or current market quotations provided by dealers or prices (including evaluated prices) supplied by the Fund's approved independent third-party pricing services, each in accordance with valuation policies and procedures approved by the Board. Pricing services may use matrix pricing or valuation models that utilize certain inputs and assumptions to derive values. Pricing services generally value fixed-income securities assuming orderly transactions of an institutional round lot size, but the Fund may hold

or transact in such securities in smaller odd lot sizes. Odd lots often trade at lower prices than institutional round lots. An amortized cost method of valuation may be used with respect to debt obligations with sixty days or less remaining to maturity unless BFA determines in good faith that such method does not represent fair value.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid at least once a year by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC

participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, in which case your distributions generally will be taxable when withdrawn, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares. In general, given its investment strategy, the Fund would not be an appropriate investment for a tax deferred retirement account such as an IRA or a tax-exempt investor.

Taxes on Distributions.

Dividends paid by the Fund that are properly reported as tax-exempt interest dividends will not be subject to regular U.S. federal income tax. The Fund intends to invest its assets in a manner such that dividend distributions to its shareholders will generally be exempt from U.S. federal income taxation, including the federal AMT. Dividends paid by the Fund will be exempt from U.S. federal income tax (though not necessarily exempt from state and local taxation) to the extent of the Fund’s tax-exempt interest income as long as 50% or more of the value of the Fund’s assets at the end of each quarter is invested in state, municipal and other bonds that are excluded from gross income for U.S. federal income tax purposes and as long as the Fund properly reports such dividends as tax-exempt interest dividends. Exempt interest dividends from interest earned on municipal securities of a state, or its political subdivisions, may be exempt from income tax in that state. However, income from municipal securities of other states generally will not qualify for tax-free treatment.

Distributions from the Fund’s net investment income other than from net tax-exempt income, including distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. The Fund's distributions of net long-term capital gains, if any, in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, regardless of how long you have held the Fund’s shares. Long-term capital gains are eligible for taxation at a maximum rate of 15% or 20% for non-corporate shareholders, depending on whether their income exceeds certain threshold amounts. Taxable distributions from the Fund are subject to a 3.8% U.S. federal Medicare contribution tax on “net investment income,” for

individuals with incomes exceeding $200,000 ($250,000 if married and filing jointly) and of estates and trusts. Distributions from the Fund are not expected to qualify as qualified dividend income. In general, any taxable distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

Any market discount recognized on a bond is taxable as ordinary income. A market discount bond is a bond acquired in the secondary market at a price below redemption value or adjusted issue price if issued with original issue discount. To the extent the Fund does not include the market discount in income as it accrues, gain on the Fund's disposition of such an obligation will be treated as ordinary income rather than capital gain to the extent of the accrued market discount.

If you lend your Fund shares pursuant to securities lending arrangements, you may lose the ability to treat Fund dividends (paid while the shares are held by the borrower) as tax-exempt income. Consult your financial intermediary or tax advisor.

Separately, a 30% withholding tax is currently imposed on U.S.-source dividends, interest and other income items and will be imposed on proceeds from the sale, redemption or other disposition of property producing U.S.-source dividends and interest paid after December 31, 2018, to (i) foreign financial institutions, including non-U.S. investment funds, unless they agree to collect and disclose to the IRS information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to (i) enter into agreements with the IRS that state that they will provide the IRS information, including the names, addresses and taxpayer identification numbers of direct and indirect U.S. account holders; comply with due diligence procedures with respect to the identification of U.S. accounts; report to the IRS certain information with respect to U.S. accounts maintained; agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information; and determine certain other information as to their account holders, or (ii) in the event that an applicable intergovernmental agreement and implementing legislation are adopted, provide local revenue authorities with similar account holder information. Other foreign entities may need to report the name, address, and taxpayer identification number of each substantial U.S. owner or provide certifications of no substantial U.S. ownership, unless certain exceptions apply.

Shareholders will receive information after the end of each year setting forth the amount of dividends and long-term capital gains distributed to them by the Fund during the prior year. Likewise, the amount of tax-exempt income, including any tax-exempt income subject to AMT, that the Fund distributes will be reported and such income must be reported on the shareholder’s U.S. federal income tax return. The AMT is a separate tax system that operates in parallel to the regular federal income tax system but eliminates many deductions and exclusions. The AMT has different tax

rates and treats as taxable certain types of income that are nontaxable for regular income tax purposes. The interest on certain “private activity” municipal bonds is taxable income for AMT purposes. If a taxpayer’s overall AMT liability is higher than regular income tax liability, then the taxpayer owes the regular income tax liability plus the difference between the AMT liability and the regular income tax liability.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) (“Deposit Securities”) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation baskets will generally correspond to the price and yield performance of the Fund. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities (including any portion of such securities for which cash may be substituted) held by the Fund (“Fund Securities”) and a specified amount of cash. Except when aggregated in Creation Units, shares are not redeemable by the Fund.

The Deposit Securities required for purchase of a Creation Unit may be different than the Fund Securities the Fund will deliver upon redemption of Fund shares. The Deposit Securities and Fund Securities, as applicable, in connection with a purchase or

redemption of a Creation Unit, generally will correspond pro rata, to the extent practicable, to the securities held by the Fund.

below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, price movement and other costs and expenses related to cash transactions (which may, in certain instances, be based on a good faith estimate of transaction costs). Investors who use the services of a broker or other financial intermediary to acquire or dispose of Fund shares may pay fees for such services.

iSHARES^® iBONDS^® SEP 2019 TERM MUNI BOND ETF

Ticker: IBMH

Stock Exchange: NYSE Arca

Investment Objective

The iShares iBonds Sep 2019 Term Muni Bond ETF (the “Fund”) seeks to track the investment results of an index composed of investment-grade U.S. municipal bonds maturing after May 31 and before September 2, 2019.

Fees and Expenses

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

Annual Fund Operating Expenses (ongoing expenses that you pay each year as a percentage of the value of your investments)
Management Fees	Distribution and Service (12b-1) Fees	Other Expenses	Total Annual Fund Operating Expenses
0.18%	None	None	0.18%

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. Fund expenses are calculated only through September 1, 2019 because the Fund is scheduled to cease operations and liquidate on or around that date. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

	1 Year		Maturity
	$18		$20

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P AMT-Free Municipal Series 2019 Index^TM (the “Underlying Index”), which measures the performance of investment-grade (as determined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”)), non-callable U.S. municipal bonds maturing in 2019. As of March 31, 2018, there were 4,150 issues in the Underlying Index.

each rebalancing date. All bonds in the Underlying Index will mature after May 31 and before September 2 of the year referenced in the name of the Underlying Index. When a bond in the Underlying Index matures or is pre-refunded, the bond does not accrue interest past the maturity or pre-refunded date. An amount representing its value at the time of maturity or pre-refunding will be included in the Underlying Index throughout the remaining life of the Underlying Index, and any such amount will be assumed to earn a rate equal to the tax-exempt return of cash and cash equivalents. The Underlying Index is a market value weighted index and is rebalanced after the market close on the last business day of each month.

S-2

turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to that of an applicable underlying index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability, duration, maturity, credit ratings and yield) and liquidity measures similar to those of an applicable underlying index. The Fund may or may not hold all of the securities in the Underlying Index.

the Fund track the Underlying Index. The Fund will generally hold municipal bond securities issued by state and local municipalities whose interest payments are exempt from U.S. federal income tax, the federal AMT and the federal Medicare contribution tax of 3.8% on “net investment income,” including dividends, interest and capital gains. In the last months of operation, as the bonds held by the Fund mature, the proceeds will not be reinvested in bonds but instead will be held in cash and cash equivalents, including, without limitation, money market funds affiliated with BFA, AMT-free tax-exempt municipal notes, variable rate demand notes and obligations, tender option bonds and municipal commercial paper. These cash equivalents may not be included in the Underlying Index. By September 1, 2019, the Underlying Index is expected to consist entirely of cash earned in this manner. Around the same time, the Fund will wind up and terminate, and its net assets will be distributed to then-current shareholders. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

Summary of Principal Risks

S-4

Fluctuation of Yield and Liquidation Amount Risk. The Fund, unlike a direct investment in a municipal bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. It is expected that an investment in the Fund, if held through maturity, will produce aggregate returns comparable to a direct investment in a group of municipal bonds of similar credit quality and maturity. Unlike a direct investment in municipal bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund's existence it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund's portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in municipal bonds. If the amount you receive as liquidation proceeds upon the Fund's termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Income Risk. The Fund's income may decline when interest rates fall. This decline can occur because the Fund may subsequently invest in lower-

yielding bonds as bonds in its portfolio mature or are near maturity, bonds in the Underlying Index are substituted with cash and cash equivalents, or the Fund otherwise needs to purchase additional bonds.

Interest Rate Risk. An increase in interest rates may cause the value of securities held by the Fund to decline, may lead to heightened volatility in the fixed-income markets and may adversely affect the liquidity of certain fixed-income investments. The historically low interest rate environment, together with recent modest rate increases, heightens the risks associated with rising interest rates.

S-5

those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Municipal Securities Risk. Municipal securities can be significantly affected by political or economic changes, including changes made in the law after issuance of the securities, as well as uncertainties in the municipal market related to taxation, legislative changes or the rights of municipal security holders, including in connection with an issuer insolvency. Municipal securities backed by current or anticipated revenues from a specific project or specific assets can be negatively

affected by the inability to collect revenues from the project or the assets.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

S-6

developments affecting a particular project can result in lower revenues to the issuer of the municipal securities. Investors in these securities, similar to investors in municipal securities generally, face heightened risk of loss upon insolvency of the school district issuers because there is often no ready source of funding to pay the bonds other than the local tax base, which a bankruptcy court or administrator does not control.

Tax Risk. There is no guarantee that the Fund's income will be exempt from U.S. federal income taxes, the federal AMT or the federal Medicare contribution tax of 3.8% on “net investment income.”

the valuation of dividends or interest, tax gains or losses, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

More Information About the Fund

The Fund will wind up and terminate on or about September 1, 2019. Upon its termination, the Fund will distribute substantially all of its net assets, after making appropriate provision for any liabilities of the Fund, to then-current shareholders pursuant to a plan of liquidation. In the final months of the Fund's operations, as the bonds it holds mature, its portfolio will transition to cash and cash-like instruments, including without limitation AMT-free tax-exempt municipal notes, variable rate demand notes and obligations, tender option bonds and municipal commercial paper. By September 1, 2019, the Underlying Index is expected to consist almost entirely of cash earned in this manner. As the Fund approaches its termination date, its holdings of money market or similar funds may increase, causing the Fund to incur the fees and expenses associated with investing in these funds. In accordance with the Trust's current Amended and Restated Agreement and Declaration of Trust, the Fund will terminate on or about the date noted above as approved by a majority of the Trust's Board of Trustees (the “Board”) without requiring additional approval by Fund shareholders. The Board may extend the termination date if a majority of the Board determines the extension to be in the best interest of the Fund.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Asset Class Risk. The securities and other assets in the Underlying Index or in the Fund’s portfolio may underperform in comparison to other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities, currencies and indexes may experience cycles of outperformance and underperformance in comparison to the general financial markets. This may cause the Fund to underperform other investment vehicles that invest in different asset classes.

Income Risk. The Fund’s income may decline when interest rates fall. This decline can occur because the Fund may subsequently invest in lower-yielding bonds as bonds in

The market for municipal bonds may be less liquid than for taxable bonds. There may also be less information available on the financial condition of issuers of municipal

Market Trading Risk

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below the Fund’s most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Fund's shares fluctuates continuously throughout trading hours based on both market supply of and demand for Fund shares and the underlying value of the Fund's portfolio holdings or NAV. As a result, the trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility, including during periods of significant redemption requests or other unusual market conditions. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV, BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long term (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs). While the creation/redemption feature is designed to make it more likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund's NAV due to timing reasons, supply and demand imbalances and other factors. In addition, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants, or other market participants, and during periods of significant market volatility, may result in trading prices for shares of the Fund that differ significantly from its NAV. Authorized Participants may be less willing to create or redeem Fund shares if there is a lack of an active market for such shares or its underlying investments, which may contribute to the Fund’s shares trading at a premium or discount to NAV.

equivalents held by the Fund may be subject to the federal AMT or the federal Medicare contribution tax.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

prohibit the Fund from exercising default rights due to a receivership or similar proceeding of an affiliate of the counterparty. Implementation of these requirements may increase credit and other risks to the Fund.

Utilities Sector Risk. Deregulation may subject utility companies to greater competition and may adversely affect their profitability. As deregulation allows utility companies to diversify outside of their original geographic regions and their traditional lines of business, utility companies may engage in riskier ventures. In addition, deregulation may eliminate restrictions on the profits of certain utility companies, but may also subject these companies to greater risk of loss. Companies in the utilities industry may have difficulty obtaining an adequate return on invested capital, raising capital, or financing large construction projects during periods of inflation or unsettled capital markets; face restrictions on operations and increased cost and delays attributable to environmental considerations and regulation; find that existing plants, equipment or products have been rendered obsolete by technological innovations; or be subject to increased costs because of the scarcity of certain fuels or the effects of man-made or natural disasters. Existing and future regulations or legislation may make it difficult for utility companies to operate profitably. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. There is no assurance that regulatory authorities will grant rate increases in the future or that such increases will be adequate to permit the payment of coupon payments on bonds issued by or in respect to such companies. Energy conservation and changes in climate policy may also have a significant adverse impact on the revenues and expenses of utility companies.

Shareholder Information

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as the supply of and demand for ETF shares and underlying securities held by the Fund, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout each trading day by the national securities exchange on which the Fund's shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities or other assets and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities or other assets held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund's NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and price quotations obtained from broker-dealers and other market intermediaries that may trade in the portfolio securities or other assets held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the U.S. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid at least once a year by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC

participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Taxes on Distributions.

Separately, a 30% withholding tax is currently imposed on U.S.-source dividends, interest and other income items and will be imposed on proceeds from the sale, redemption or other disposition of property producing U.S.-source dividends and interest paid after December 31, 2018, to (i) foreign financial institutions, including non-U.S. investment funds, unless they agree to collect and disclose to the IRS information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to (i) enter into agreements with the IRS that state that they will provide the IRS information, including the names, addresses and taxpayer identification numbers of direct and indirect U.S. account holders; comply with due diligence procedures with respect to the identification of U.S. accounts; report to the IRS certain information with respect to U.S. accounts maintained; agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information; and determine certain other information as to their account holders, or (ii) in the event that an applicable intergovernmental agreement and implementing legislation are adopted, provide local revenue authorities with similar account holder information. Other foreign entities may need to report the name, address, and taxpayer identification number of each substantial U.S. owner or provide certifications of no substantial U.S. ownership, unless certain exceptions apply.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) (“Deposit Securities”) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation baskets will generally correspond to the price and yield performance of the Fund. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities (including any portion of such securities for which cash may be substituted) held by the Fund (“Fund Securities”) and a specified amount of cash. Except when aggregated in Creation Units, shares are not redeemable by the Fund.

iSHARES^® iBONDS^® SEP 2020 TERM MUNI BOND ETF

Ticker: IBMI

Stock Exchange: NYSE Arca

Investment Objective

The iShares iBonds Sep 2020 Term Muni Bond ETF (the “Fund”) seeks to track the investment results of an index composed of investment-grade U.S. municipal bonds maturing after May 31 and before September 2, 2020.

Fees and Expenses

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

Annual Fund Operating Expenses (ongoing expenses that you pay each year as a percentage of the value of your investments)
Management Fees	Distribution and Service (12b-1) Fees	Other Expenses	Total Annual Fund Operating Expenses
0.18%	None	None	0.18%

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. Fund expenses are calculated only through September 1, 2020 because the Fund is scheduled to cease operations and liquidate on or around that date. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

	1 Year		Maturity
	$18		$40

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P AMT-Free Municipal Series 2020 Index^TM (the “Underlying Index”), which measures the performance of investment-grade (as determined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”)), non-callable U.S. municipal bonds maturing in 2020. As of March 31, 2018, there were 3,866 issues in the Underlying Index.

The Underlying Index includes municipal bonds primarily from issuers that are state or local governments or agencies such that the interest on the bonds is exempt from U.S. federal income taxes. The Underlying Index does not include municipal issuers from U.S. territories, such as Puerto Rico. Each bond must have a rating of at least BBB- by S&P Global Ratings (“S&P”), Baa3 by Moody’s Investors Service, Inc. (“Moody's”), or BBB- by Fitch Ratings, Inc. and must have a minimum maturity par amount of $2 million to be eligible for inclusion in the Underlying Index. To remain in the Underlying Index, bonds must maintain a minimum par amount

greater than or equal to $2 million, and must not be subject to the federal alternative minimum tax (“AMT”) as of each rebalancing date. All bonds in the Underlying Index will mature after May 31 and before September 2 of the year referenced in the name of the Underlying Index. When a bond in the Underlying Index matures or is pre-refunded, the bond does not accrue interest past the maturity or pre-refunded date. An amount representing its value at the time of maturity or pre-refunding will be included in the Underlying Index throughout the remaining life of the Underlying Index, and any such amount will be assumed to earn a rate equal to the tax-exempt return of cash and cash equivalents. The Underlying Index is a market value weighted index and is rebalanced after the market close on the last business day of each month.

S-2

lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to that of an applicable underlying index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability, duration, maturity, credit ratings and yield) and liquidity measures similar to those of an applicable underlying index. The Fund may or may not hold all of the securities in the Underlying Index.

securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. The Fund will generally hold municipal bond securities issued by state and local municipalities whose interest payments are exempt from U.S. federal income tax, the federal AMT and the federal Medicare contribution tax of 3.8% on “net investment income,” including dividends, interest and capital gains. In the last months of operation, as the bonds held by the Fund mature, the proceeds will not be reinvested in bonds but instead will be held in cash and cash equivalents, including, without limitation, money market funds affiliated with BFA, AMT-free tax-exempt municipal notes, variable rate demand notes and obligations, tender option bonds and municipal commercial paper. These cash equivalents may not be included in the Underlying Index. By September 1, 2020, the Underlying Index is expected to consist entirely of cash earned in this manner. Around the same time, the Fund will wind up and terminate, and its net assets will be distributed to then-current shareholders. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

S-3

concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities), repurchase agreements collateralized by U.S. government securities, and securities of state or municipal governments and their political subdivisions are not considered to be issued by members of any industry.

Summary of Principal Risks

premium or discount to NAV and possibly face trading halts or delisting.

S-4

Participants or issuers of securities in which the Fund invests.

Fluctuation of Yield and Liquidation Amount Risk. The Fund, unlike a direct investment in a municipal bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. It is expected that an investment in the Fund, if held through maturity, will produce aggregate returns comparable to a direct investment in a group of municipal bonds of similar credit quality and maturity. Unlike a direct investment in municipal bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund's existence it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund's portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in municipal bonds. If the amount you receive as liquidation proceeds upon the Fund's termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. The Fund invests in

S-5

municipal bonds of issuers that are primarily state or local governments or agencies. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

issuer insolvency. Municipal securities backed by current or anticipated revenues from a specific project or specific assets can be negatively affected by the inability to collect revenues from the project or the assets.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

S-6

particular school district project often depend on revenues from that project to make principal and interest payments. Adverse conditions and developments affecting a particular project can result in lower revenues to the issuer of the municipal securities. Investors in these securities, similar to investors in municipal securities generally, face heightened risk of loss upon insolvency of the school district issuers because there is often no ready source of funding to pay the bonds other than the local tax base, which a bankruptcy court or administrator does not control.

Tax Risk. There is no guarantee that the Fund's income will be exempt from U.S. federal income taxes, the federal AMT or the federal Medicare contribution tax of 3.8% on “net investment income.”

More Information About the Fund

The Fund will wind up and terminate on or about September 1, 2020. Upon its termination, the Fund will distribute substantially all of its net assets, after making appropriate provision for any liabilities of the Fund, to then-current shareholders pursuant to a plan of liquidation. In the final months of the Fund's operations, as the bonds it holds mature, its portfolio will transition to cash and cash-like instruments, including without limitation AMT-free tax-exempt municipal notes, variable rate demand notes and obligations, tender option bonds and municipal commercial paper. By September 1, 2020, the Underlying Index is expected to consist almost entirely of cash earned in this manner. As the Fund approaches its termination date, its holdings of money market or similar funds may increase, causing the Fund to incur the fees and expenses associated with investing in these funds. In accordance with the Trust's current Amended and Restated Agreement and Declaration of Trust, the Fund will terminate on or about the date noted above as approved by a majority of the Trust's Board of Trustees (the “Board”) without requiring additional approval by Fund shareholders. The Board may extend the termination date if a majority of the Board determines the extension to be in the best interest of the Fund.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Asset Class Risk. The securities and other assets in the Underlying Index or in the Fund’s portfolio may underperform in comparison to other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities, currencies and indexes may experience cycles of outperformance and underperformance in comparison to the general financial markets. This may cause the Fund to underperform other investment vehicles that invest in different asset classes.

Income Risk. The Fund’s income may decline when interest rates fall. This decline can occur because the Fund may subsequently invest in lower-yielding bonds as bonds in

The market for municipal bonds may be less liquid than for taxable bonds. There may also be less information available on the financial condition of issuers of municipal

Market Trading Risk

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below the Fund’s most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Fund's shares fluctuates continuously throughout trading hours based on both market supply of and demand for Fund shares and the underlying value of the Fund's portfolio holdings or NAV. As a result, the trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility, including during periods of significant redemption requests or other unusual market conditions. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV, BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long term (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs). While the creation/redemption feature is designed to make it more likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund's NAV due to timing reasons, supply and demand imbalances and other factors. In addition, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants, or other market participants, and during periods of significant market volatility, may result in trading prices for shares of the Fund that differ significantly from its NAV. Authorized Participants may be less willing to create or redeem Fund shares if there is a lack of an active market for such shares or its underlying investments, which may contribute to the Fund’s shares trading at a premium or discount to NAV.

equivalents held by the Fund may be subject to the federal AMT or the federal Medicare contribution tax.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Utilities Sector Risk. Deregulation may subject utility companies to greater competition and may adversely affect their profitability. As deregulation allows utility companies to diversify outside of their original geographic regions and their traditional lines of business, utility companies may engage in riskier ventures. In addition, deregulation may eliminate restrictions on the profits of certain utility companies, but may also subject these companies to greater risk of loss. Companies in the utilities industry may have difficulty obtaining an adequate return on invested capital, raising capital, or financing large construction projects during periods of inflation or unsettled capital markets; face restrictions on operations and increased cost and delays attributable to environmental considerations and regulation; find that existing plants, equipment or products have been rendered obsolete by technological innovations; or be subject to increased costs because of the scarcity of certain fuels or the effects of man-made or natural disasters. Existing and future regulations or legislation may make it difficult for utility companies to operate profitably. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. There is no assurance that regulatory authorities will grant rate increases in the future or that such increases will be adequate to permit the payment of coupon payments on bonds issued by or in respect to such companies. Energy conservation and changes in climate policy may also have a significant adverse impact on the revenues and expenses of utility companies.

Shareholder Information

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as the supply of and demand for ETF shares and underlying securities held by the Fund, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout each trading day by the national securities exchange on which the Fund's shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities or other assets and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities or other assets held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund's NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and price quotations obtained from broker-dealers and other market intermediaries that may trade in the portfolio securities or other assets held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the U.S. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid at least once a year by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC

participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Separately, a 30% withholding tax is currently imposed on U.S.-source dividends, interest and other income items and will be imposed on proceeds from the sale, redemption or other disposition of property producing U.S.-source dividends and interest paid after December 31, 2018, to (i) foreign financial institutions, including non-U.S. investment funds, unless they agree to collect and disclose to the IRS information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to (i) enter into agreements with the IRS that state that they will provide the IRS information, including the names, addresses and taxpayer identification numbers of direct and indirect U.S. account holders; comply with due diligence procedures with respect to the identification of U.S. accounts; report to the IRS certain information with respect to U.S. accounts maintained; agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information; and determine certain other information as to their account holders, or (ii) in the event that an applicable intergovernmental agreement and implementing legislation are adopted, provide local revenue authorities with similar account holder information. Other foreign entities may need to report the name, address, and taxpayer identification number of each substantial U.S. owner or provide certifications of no substantial U.S. ownership, unless certain exceptions apply.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) (“Deposit Securities”) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation baskets will generally correspond to the price and yield performance of the Fund. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities (including any portion of such securities for which cash may be substituted) held by the Fund (“Fund Securities”) and a specified amount of cash. Except when aggregated in Creation Units, shares are not redeemable by the Fund.

Principal Investment Strategies

The Fund seeks to track the investment results of the Nifty 50 Index^TM (the “Underlying Index”), which measures the equity performance of the top 50 companies by free float market capitalization whose equity securities trade in the Indian securities markets, as determined by India Index Services & Products Ltd. (the “Index Provider” or “IISL”). As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the financials industry or sector. The components of the Underlying Index are likely to change over time.

The Fund carries out its investment strategies by investing substantially all of its assets through a wholly-owned subsidiary in the Republic of Mauritius (the “Subsidiary”). The remaining assets will be invested directly by the Fund. The Subsidiary and the Fund generally will collectively invest at least 90% of the Fund's assets in the component securities of the Underlying Index and in investments that have economic characteristics that are substantially

identical to the component securities of the Underlying Index (i.e., depositary receipts representing securities of the Underlying Index). Subject to recent legislative developments in India, the Fund may choose to withdraw from the Subsidiary, which may increase the Fund's India tax expenses. BFA serves as investment adviser to both the Fund and the Subsidiary. Unless otherwise indicated, the term “Fund,” as used in this prospectus (the “Prospectus”), means the Fund and/or the Subsidiary, as applicable.

S-2

return variability and yield) and liquidity measures similar to those of an applicable underlying index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund may invest up to 10% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, as well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

The Underlying Index is a product of IISL, which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

Summary of Principal Risks

Cash Transactions Risk. The Fund expects to effect all of its creations and redemptions for cash, rather than in-kind securities. As a result, the Fund may have to sell portfolio securities at

S-3

inopportune times in order to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. The use of cash creations and redemptions may also cause the Fund’s shares to trade in the market at wider bid-ask spreads or greater premiums or discounts to the Fund’s NAV.

Geographic Risk. A natural disaster could occur in India or Mauritius, which could adversely affect the Indian economy or operations of the

S-4

Subsidiary, causing an adverse impact on the Fund.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over

longer periods during more prolonged market downturns.

S-5

or impossible at times. The Fund is specifically exposed to Asian Economic Risk.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. India has privatized, or has begun the process of privatizing, certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk. The Fund invests in India, which is heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund's investments.

Risk of Investing in Emerging Markets. The Fund's investments in India may be subject to a greater risk of loss than investments in issuers located or operating in more developed markets. Emerging markets may be more likely to experience inflation, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, less reliable securities valuations and greater risk associated with custody of securities than developed markets.

Risk of Investing in India. Investments in Indian issuers involve risks that are specific to India, including legal, regulatory, political and economic risks. Political and legal uncertainty, greater government control over the economy, currency fluctuations or blockage, and the risk of nationalization or expropriation of assets may result in higher potential for losses. The securities markets in India are relatively underdeveloped and may subject the Fund to higher transaction costs or greater uncertainty than investments in more developed securities markets. India has experienced security concerns, such as terrorism and strained international relations. Incidents involving India's or the region's security may cause uncertainty in the Indian market and may adversely affect the Indian economy and the Fund's investments.

Structural Risk. The country in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

S-6

Treaty/Tax Risk. The Fund and the Subsidiary rely on the Double Tax Avoidance Agreement between India and Mauritius (“DTAA”) for relief from certain Indian taxes. The DTAA has been renegotiated and as such, treaty relief is reduced or not available on investments in securities made on or after April 1, 2017, which may result in higher taxes and/or lower returns for the Fund. After April 1, 2017, the Fund may continue to

invest in the Subsidiary until an alternative method for investing in the securities of Indian issuers is selected.

A Further Discussion of Principal Risks

Asset Class Risk. The securities and other assets in the Underlying Index or in the Fund’s portfolio may underperform in comparison to other securities or indexes that

track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities, currencies and indexes may experience cycles of outperformance and underperformance in comparison to the general financial markets depending upon a number of factors including, among other things, inflation, interest rates, productivity, global demand for local products or resources, and regulation and governmental controls. This may cause the Fund to underperform other investment vehicles that invest in different asset classes.

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Cash Transactions Risk. Unlike most other ETFs, the Fund expects to effect all of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund’s shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. As a practical matter, only institutions and large investors, such as market makers or other large broker dealers, create or redeem shares directly through the Fund. Most investors will buy and sell shares of the Fund on an exchange through a broker-dealer. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

Financials Sector Risk. Companies in the financials sector of an economy are subject to extensive governmental regulation and intervention, which may adversely affect the scope of their activities, the prices they can charge, the amount of capital they must maintain and, potentially, their size. The extent to which the Fund may invest in a company that engages in securities-related activities or banking is limited by applicable law. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financials sector, including effects not intended by such regulation. Recently enacted legislation in the U.S. has relaxed capital requirements and other regulatory burdens on certain U.S. banks. While the effect of the legislation may benefit certain companies in the financials sector, increased risk tasking by affected banks may also result in greater overall risk in the financials sector. The impact of changes in capital requirements, or recent or future regulation in various countries of any individual financial company or of the financials sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financials sector more severely than those of investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financials sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Insurance companies, in particular, may be subject to severe price competition and/or rate regulation, which may have an adverse impact on their profitability. The banking industry, in particular, is negatively affected by interest rates when they remain low for long periods of time as banks are more profitable when there is a larger spread between the federal funds rate and what depositories pay in interest. The financials sector is particularly sensitive to fluctuations in interest rates. The financials sector is also a target for cyber attacks, and may experience technology malfunctions and disruptions. In recent years, cyber attacks and technology failures have become increasingly frequent in this sector and have reportedly caused losses to companies in this sector, which may negatively impact the Fund.

Geographic Risk. India and Mauritius are located in parts of the world that have historically been prone to natural disasters such as earthquakes, volcanic eruptions or tsunamis, and India is economically sensitive to environmental events. In addition, the agricultural sector is an important component of the Indian economy and any such event may adversely impact the Indian economy and could impact operations of the wholly-owned subsidiary in Mauritius, causing an adverse impact on the value of the Fund.

Market Trading Risk

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such

times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

regulatory and other charges that are incurred as a result of trading activity. Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments through a brokerage account.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Privatization Risk. India has privatized, or has begun the process of privatizing, certain entities and industries. Newly privatized companies may face strong competition from government-sponsored competitors that have not been privatized. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that similar losses will not recur.

Reliance on Trading Partners Risk. The Indian economy is dependent on commodity prices and the economies of Asia, mainly Japan and China, and the U.S. as key trading partners. Reduction in spending on Indian products and services by any of these trading partners or a slowdown or recession in any of these economies could adversely affect the Indian economy.

Risk of Investing in India. India is an emerging market country and exhibits significantly greater market volatility from time to time in comparison to more developed markets. Political and legal uncertainty, greater government control over the economy, currency fluctuations or blockage, and the risk of nationalization or expropriation of assets may result in higher potential for losses.

Moreover, governmental actions can have a significant effect on the economic conditions in India, which could adversely affect the value and liquidity of the Fund's investments. In November 2016, the Indian government eliminated certain large denomination cash notes as legal tender, causing uncertainty in certain financial markets. The securities markets in India are comparatively underdeveloped, and

stockbrokers and other intermediaries may not perform as well as their counterparts in the U.S. and other more developed securities markets. The limited liquidity of the Indian securities markets may also affect the Fund’s ability to acquire or dispose of securities at the price and time that it desires.

Global factors and foreign actions may inhibit the flow of foreign capital on which India is dependent to sustain its growth. In addition, the Reserve Bank of India (“RBI”) has imposed limits on foreign ownership of Indian securities, which may decrease the liquidity of the Fund’s portfolio and result in extreme volatility in the prices of Indian securities. These factors, coupled with the lack of extensive accounting, auditing and financial reporting standards and practices, as compared to the U.S., may increase the Fund's risk of loss.

Further, certain Indian regulatory approvals, including approvals from the Securities and Exchange Board of India (“SEBI”), the RBI, the central government and the tax authorities (to the extent that tax benefits need to be utilized), may be required before the Fund can make investments in the securities of Indian companies. Capital gains from Indian securities may be subject to local taxation.

India has experienced acts of terrorism and has strained international relations with Pakistan, Bangladesh, China, Sri Lanka and other neighbors due to territorial disputes, historical animosities, terrorism, defense concerns and other security concerns. These situations may cause uncertainty in the Indian market and may adversely affect the Indian economy.

currency hedging instruments.

Large Government Debt Risk. Chronic structural public sector deficits in some countries in which the Fund may invest may adversely impact securities held by the Fund.

Treaty/Tax Risk. The Fund operates, in part, through the Subsidiary, which in turn invests in securities of Indian issuers.

An investor is required to submit the tax residency certificate as issued in the country of residence and provide other documents and information as prescribed by the Government of India to claim benefits under the DTAA.

The revised DTAA provides that capital gains that arise from alienation of shares of an Indian company acquired by a Mauritian tax resident, on or after April 1, 2017, would be taxable in India. However, the DTAA also provides for grandfathering of investments in shares made before April 1, 2017. Returns from investments in shares made on or after April 1, 2017 will be subject to capital gains tax in India, although the DTAA provides for a limitation of benefits provision which shall be a prerequisite for a reduced rate of tax (50% of domestic tax rate) on capital gains arising during a two year transition period from April 1, 2017 to March 31, 2019. The application of such provisions of the DTAA could result in the imposition of withholding and capital gains taxes and/or other taxes on the Subsidiary by tax authorities in India. This could significantly reduce the return to the Fund on its investments in shares and the return received by the Fund’s shareholders.

Criteria for Residence of Companies in India.

applied taking the relevant financial year as a whole into consideration. The Central Board of Direct Taxes (“CBDT”) has clarified that the provisions in relation to POEM shall not apply to a company having turnover of INR 500 million or less in a year.

Indirect Transfers.

The current legislation, (Indian) Income Tax Act, 1961 (“IT Act”) imposes Indian tax and withholding obligations with respect to the transfer of shares and interest in an overseas company that derives its value substantially from assets situated in India (“indirect transfers”). It has been clarified that Indian tax authorities will not reopen any assessment proceedings that were completed before April 1, 2012 and where no notice for reassessment has been issued prior to that date. The CBDT also clarified that any assessment or any other order which stands validated due to the amendments in the Finance Act would be enforced. Given this clarification issued by the CBDT, the Fund does not expect that shareholders or the Fund will become subject to tax or to withholding obligations with respect to completed assessments.

It has been clarified that the share or interest of the foreign entity shall be deemed to derive its value substantially from the assets located in India, if the value of such Indian assets exceeds INR 100 million, and represents at least 50% of the value of all the assets owned by the foreign entity. The value of an asset shall be the fair market value as of the specified date, of such an asset without reduction of liabilities. The fair market value will be determined in accordance with Rule 11UB of the Income Tax Rule, 1962 (“IT Rules”). In case all the assets of the foreign entity are not located in India, only such part of the income as is reasonably attributable to the Indian assets shall be subject to capital gains tax in India.

Further, it provides an exemption from indirect transfer provisions to the small shareholders of such foreign entity in the following cases:

■

With respect to a foreign entity that holds the Indian assets directly, if the transferor of share or interest in such a foreign entity (along with its associated enterprises), at any time in the twelve months preceding the year of transfer neither holds the right of control or management in the foreign entity, nor holds voting power or share capital or interest exceeding 5% of the total voting power or total share capital or total interest in such foreign entity.

■

With respect to a foreign entity that holds the Indian assets indirectly, if the transferor of share or interest in such foreign entity (along with its associated enterprises), at any time in the twelve months preceding the year of transfer does not hold the right of control or management in relation to the foreign entity, which would entitle them to the right of control or management in the foreign entity which directly holds the Indian assets; or does not hold voting power or share capital or interest exceeding 5% of the total voting power or total share capital or total interest in the foreign entity, which results in holding the same share capital or voting power in the entity which directly holds the Indian assets.

Gains realized when a non-resident acquires shares of a foreign company from another non-resident and the foreign company derives “substantial value” from Indian assets, (meaning that the value of Indian assets (i) exceeds INR 100 million, and (ii) represents at least 50% of the value the company’s assets), such gains are taxable in India and subject to withholding, to the extent that they are reasonably attributable to the Indian assets.

Because the Fund invests in Indian securities through the Subsidiary, the Subsidiary or the Fund may be considered to derive “substantial value” from Indian assets, and accordingly, shareholder redemptions of Fund/Subsidiary shares and sales of Fund shares may have been subject to Indian tax and withholding obligations. However, the IT Act provides for an exemption to shareholders in Category I and Category II foreign portfolio investors (“FPI”) from the applicability of indirect transfer taxation. The Subsidiary is a Category II FPI. Therefore, any redemptions or transfers by the Fund or the shareholders in the Fund should not be subject to Indian indirect transfer tax.

The IT Act further provides that the aforesaid indirect transfer provisions will not apply to foreign investors making an investment directly or indirectly in a SEBI registered Category I and Category II foreign portfolio investor.

General Anti-Avoidance Rules.

The current legislation provides for the general anti-avoidance rules (“GAAR”) to curb aggressive tax planning with the use of sophisticated structures. GAAR became applicable with effect from April 1, 2017. CBDT vide Circular No. 7 of 2017 has clarified that where a FPI (such as the Subsidiary) is located in a particular jurisdiction based on non-tax commercial reasons and the main purpose of the choice of location/residence of the FPI is not to obtain a treaty benefit, the GAAR provisions will not be resorted to by the tax authorities.

As per the provisions of GAAR, an arrangement entered into by a taxpayer may be declared to be an impermissible avoidance arrangement, if the “main purpose” of the arrangement is to obtain a “tax benefit” and the arrangement:

■	creates rights, or obligations, which are not ordinarily created between persons dealing at arm's length;
■	results, directly or indirectly, in the misuse, or abuse, of the provisions of IT Act;
■	lacks commercial substance; or
■	is entered into, or carried out, by means, or in a manner, which are not ordinarily employed for bona fide purposes.

Once an arrangement is declared to be an impermissible avoidance arrangement, wide powers have been granted to tax authorities to deny tax treaty benefits, disregard or re-characterize transactions, re-characterize equity into debt and vice versa.

As per the provisions of the IT Rules, GAAR shall not apply in the following circumstances:

■	any arrangement where the aggregate tax benefit to all the parties of the arrangement in the relevant financial year does not exceed INR 30 Million;
■	foreign institutional investors (“FIIs”) that choose not to take any benefit under any

tax treaty entered with India and have invested in listed or unlisted securities with prior permission of the competent authority in accordance with the applicable regulations;

■	non-resident investor in an FII who has invested in an FII, directly or indirectly, by way of an offshore derivative instrument or otherwise; or

■	any income derived from the transfer of shares or interests made prior to April 1, 2017.

GAAR may, irrespective of existing treaty provisions, lead to the imposition of tax liabilities and withholding obligations, and may lead the Fund to modify the structure.

Indian Minimum Alternative Tax.

The IT Act provides that Minimum Alternate Tax (“MAT”) is not applicable on foreign company where the foreign company is a resident of a country with which India has signed a DTAA and the foreign company does not have a permanent establishment in India in accordance with such DTAA.

Recent amendments to the DTAA and GAAR could change the manner in which the Subsidiary is currently taxed in India and could adversely impact the returns to the Fund/Subsidiary and its shareholders. The Fund will continue to monitor developments in India with respect to these matters. Investors are urged to consult their own tax advisers with respect to their own tax situations and the tax consequences of an investment in the Fund.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Automotive Sub-Industry Risk. The automotive sub-industry can be highly cyclical and companies in this sub-industry may suffer periodic operating losses. Companies in this sub-industry face intense competition, both domestically and internationally, which may have an adverse effect on their profitability. The sub-industry can be significantly affected by labor relations, fluctuating component and material prices, product recalls, domestic and international economic downturns and consumer demands. Government regulation and increased competition may also negatively affect automotive manufacturers. Some automotive manufacturers are small or financially vulnerable and can be non-diversified in both product line and consumer base, and may be more susceptible to adverse developments.

Consumer Goods Industry Risk. Companies in the consumer goods industry may be strongly affected by social trends, marketing campaigns and other factors affecting consumer demand. Governmental regulation affecting the use of various food additives may affect the profitability of certain consumer goods companies represented in the Underlying Index. Many consumer goods may be marketed globally, and consumer goods companies may be affected by the demand and market conditions in other countries and regions.

property, pollution or other environmental problems, equipment malfunctions or mishandling of materials and a risk of loss from terrorism, political strife or natural disasters. Any such event could have serious consequences for the general population of the affected area and could have an adverse impact on the Fund’s portfolio and the performance of the Fund. Energy companies can be significantly affected by the supply of, and demand for, specific products (e.g., oil and natural gas) and services, exploration and production spending, government subsidization, world events and general economic conditions. Energy companies may have relatively high levels of debt and may be more likely than other companies to restructure their businesses if there are downturns in energy markets or in the global economy.

Portfolio Holdings Information

Management

and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

For its investment advisory services to the Fund, BFA is paid a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.89%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Alan Mason has been employed by BFA as a portfolio manager since 1991. Mr. Mason has been a Portfolio Manager of the Fund since 2016.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

The Fund's activities may be limited because of regulatory restrictions applicable to one or more Affiliates and/or their internal policies designed to comply with such restrictions.

Shareholder Information

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund sells and redeems its shares directly through transactions that are for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

Dividends and Distributions

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

Dividends, interest and capital gains earned by the Fund with respect to securities issued by non-U.S. issuers may give rise to withholding, capital gains and other taxes

foreign tax credits passed through by the Fund if your Fund shares are loaned out pursuant to a securities lending agreement.

Mauritius Tax Disclosure. The Fund conducts its investment activities in India through the Subsidiary. In order to be eligible to claim benefits under the DTAA, the Subsidiary must satisfy certain conditions, including the establishment and maintenance of a valid tax residence in Mauritius. The Subsidiary has obtained a certificate from the Mauritius authorities providing that it is a resident of Mauritius under the DTAA. The Fund expects the Subsidiary to maintain its Mauritius tax residency. The Subsidiary is subject to tax in Mauritius on its net income at the rate of 15%. However, a system of foreign tax credits effectively reduces the Mauritius income tax rate to a maximum of 3%. Further, the Subsidiary is not subject to capital gains tax in Mauritius nor is it subject to tax in Mauritius on any gains from the sale of securities. Any dividends paid by the Subsidiary to the Fund will also be exempt from tax in Mauritius.

The amended DTAA provides that capital gains will be taxable in India with respect to shares acquired on or after April 1, 2017. Further, the tax on capital gains arising for shares both acquired and sold during the period April 1, 2017 and March 31, 2019 will be limited to 50% of the applicable tax rate if certain conditions regarding eligibility to claim DTAA benefits are met. Capital gains arising after March 31, 2019 will be subject to tax in India at the full statutory rate. Tax laws in India also include provisions that impose Indian tax on certain indirect transfers of shares of Indian companies. However, until such time that more definitive authoritative guidance on the final applicability of the DTAA amendments to the Fund is available, the impact to the Fund, if any, cannot be determined. Management is continuing to assess the impact going forward.

Indian Tax Disclosure. In the event the benefits under the DTAA are denied, the following rates of tax under the Indian IT Act will be applicable (these rates are inclusive of highest applicable surcharges):

■	Dividend: Dividend income earned by the Subsidiary will not be subject to Indian tax. However, the Indian company declaring and paying such dividend would be subject to Dividend Distribution Tax at an effective rate of 20.36% on the amount of the dividend paid out.
■	Interest: Interest paid to the Subsidiary in respect of debt obligations of Indian issuers will be subject to Indian income tax. The tax rate in the case of a rupee-denominated debt obligation is 43.68%. However if the Subsidiary is a SEBI registered foreign portfolio investor, interest income earned from June 1, 2013 to June 30, 2020 on rupee denominated bonds of Indian companies and Indian government securities will be subject to tax at the rate of 5.46%, provided that the rate of interest does not exceed the prescribed rates. In the case of a foreign-currency denominated debt obligation, the tax rate is 21.84%. For approved foreign-currency loans advanced from July 1, 2012 to June 30, 2020, the tax rate on interest is 5.46% and for approved foreign currency long-term bonds issued from October 1, 2014 to June 30, 2020, the tax rate on interest is 5.46%. The IT Act provides the withholding tax rate on rupee-denominated bonds issued before July 1, 2020 to be 5.46%. The Protocol provides for a withholding rate of 7.5% on the interest payments made on or after April 1, 2017.
■	Securities Transaction Tax: All transactions entered on a recognized stock exchange in India are subject to a Securities Transaction Tax (“STT”). STT has been introduced under Section 98 of the Finance (No.2) Act, 2004 on transactions relating to sale, purchases and redemption of shares made by purchasers or sellers of Indian securities and equity oriented mutual fund units. The current STT as levied on the transaction value as follows:

■	0.1% payable by the buyer and 0.1% by the seller on the value of transactions of delivery based transfer of an equity share in an Indian company entered in a recognized stock exchange;
■	0.001% on the value of transactions of delivery based sale of a unit of an equity oriented mutual fund entered in a recognized stock exchange, payable by the seller;
■	0.025% on the value of transactions of non-delivery based sale of an equity share in an Indian company or a unit of an equity oriented mutual fund, entered in a recognized stock exchange payable by the seller;
■	0.05% on the value of transactions of derivatives being options, entered in a recognized stock exchange. STT is to be paid by the seller;
■	0.01% on the value of transactions of sale of derivatives being futures, entered in a recognized stock exchange. STT is to be paid by the seller;
■	0.001% on the value of transactions of sale of units of an equity-oriented fund to the Mutual Fund, payable by the seller in accordance with the Finance Act, 2013;

■	0.125% on the value of transactions of sale of derivatives being options, where the option is exercised, entered in a recognized stock exchange. STT is to be paid by buyer;

■	0.2% on the value of transactions of the sale of unlisted shares by existing shareholders in an initial public offer.

■

Capital Gains: Assuming total income will be more than INR 100 million, the taxation of capital gains would be as follows: (i) long-term capital gains (being gains on sale of shares held for a period of more than 12 months) listed on a recognized stock exchange would be taxable in India at a rate of 10.92%, provided STT has been paid, both on acquisition and sale (subject to certain transactions, to which the provisions of applicability and payment of STT upon acquisition shall not be applicable) of such shares. Capital gains tax would be calculated on gains exceeding INR 0.1 million (without any indexation and foreign exchange fluctuation benefits). It may also be noted that any capital gains arising up to January 31, 2018 have been grandfathered; (ii) short-term capital gains (being gains on sale of shares held for a period of 12 months or less) from the sale of Indian shares listed on a recognized stock exchange will be taxed at the rate of 16.38% provided STT has been paid on the same; (iii) long-term capital gains (being gains on sale of shares held for a period of more than 24 months) arising to the Subsidiary from the sale of unlisted securities will be taxed at the rate of 10.92% (without indexation) and short-term capital gains (being gains on sale of shares held for a period of 24 months or less) will be taxed at the rate of 43.68% (however, if the Subsidiary is a SEBI registered sub-account, the rates will be at 10.92% and 32.76%, respectively); (iv) capital gains realized on sale of listed equity shares not executed on a recognized stock exchange in India would be taxed at the rate of 10.92% for long-term gains (being gains on sale of shares held for a period of more than 12 months) and at 43.68% in the case of short-term gains (being gains on sale of shares held for a period of 12 months or less); and (v) capital gains arising from the transfer of depositary receipts outside India between non-resident investors will not be subject to tax in India.

Indirect Transfers. The current legislation imposes Indian tax and withholding obligations with respect to the transfer of shares and interest in an overseas company that derives its value substantially from assets situated in India (indirect transfers). It has been clarified that Indian tax authorities will not reopen any assessment proceedings that were completed before April 1, 2012 and where no notice for reassessment has been issued prior to that date. The CBDT also clarified that any assessment or any other order which stands validated due to the amendments in the Finance Act would be enforced. Given this clarification issued by the CBDT, the Fund does not expect that shareholders or the Fund will become subject to tax or to withholding obligations with respect to completed assessments.

It also provides that where all the assets of the foreign entity are not located in India, only such part of the income as is reasonably attributable to the Indian assets shall be subject to capital gains tax in India.

Further, it provides an exemption from indirect transfer provisions to the small shareholders of such foreign entity in the following cases:

■

If the gains arising from transfer of shares or interests in a foreign entity are taxable in India in accordance with the aforementioned provisions of indirect transfer, the purchaser of the securities will be required to withhold applicable Indian taxes. However, the shareholders in Category I and Category II FPI are exempt from the applicability of indirect transfer taxation. The Subsidiary is a Category II FPI. Therefore, any redemptions or transfers by the Fund or the shareholders in the Fund should not be subject to Indian indirect transfer tax.

Further, indirect transfer provisions do not apply to foreign investors making an investment directly or indirectly in a SEBI registered Category I and Category II foreign portfolio investor.

General Anti-Avoidance Rules. The GAAR introduced in the IT Act provides the Indian tax authorities a mechanism to deny any tax benefits in a transaction or any other arrangement that is believed to not have any commercial substance or purpose other than to obtain tax benefit(s) under a treaty. The provisions of GAAR will be applicable to arrangements (including a step in or a part thereof) entered into by a taxpayer, which may be declared as an “impermissible avoidance arrangement”.

GAAR became applicable with effect from April 1, 2017. CBDT has clarified that where a FPI (such as the Subsidiary) is located in a particular jurisdiction based on non-tax commercial reasons and the main purpose of the choice of location/residence of the FPI is not to obtain a treaty benefit, the GAAR provisions will not be resorted to by the tax authorities.

As per the provisions of the IT Rules, GAAR shall not apply in the following circumstances:

■	any arrangement where the aggregate tax benefit to all the parties of the arrangement in the relevant financial year does not exceed INR 30 Million;
■	FIIs that choose not to take any benefit under any tax treaty entered with India and have invested in listed or unlisted securities with prior permission of the competent authority in accordance with the applicable regulations;
■	non-resident investor in an FII who has invested in an FII, directly or indirectly, by way of an offshore derivative instrument or otherwise; or

■	any income derived from the transfer of shares or interests made prior to April 1, 2017.

If the Fund's use of the Subsidiary was considered to be such an impermissible avoidance arrangement, the Fund may become subject directly to taxation in India. The burden of proof in enforcing the rule will reside with the Indian government, not the taxpayer, and India’s current double tax treaty arrangements will remain in force. However, GAAR may, irrespective of existing treaty provisions, lead to the imposition of tax liabilities and withholding obligations, which may lead the Fund to modify the structure.

These transactions are usually in exchange for cash.

Similarly, shares can be redeemed only in Creation Units, generally for a specified amount of cash. Except when aggregated in Creation Units, shares are not redeemable by the Fund.

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. The Fund

is subject to certain risks, including the principal risks noted below, any of which may adversely affect the Fund's net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

S-3

concentrated in the securities of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class.

Dividend Risk. There is no guarantee that issuers of the stocks held by the Fund will declare dividends in the future or that, if declared, they will either remain at current levels or increase over time.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Changes in the financial condition or credit rating of an issuer of

S-4

those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

S-5

address every possible risk and may be inadequate to address significant operational risks.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Real Estate Investment Risk. The Fund may invest in companies that invest in real estate (“Real Estate Companies”), such as real estate investment trusts (“REITs”) or real estate holding companies, which expose investors in the Fund to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which Real Estate Companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments, and characterized by intense competition and periodic overbuilding. Many Real Estate Companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially magnify the Fund’s losses. Rising interest rates could result in higher costs of capital for Real Estate Companies, which could negatively affect a Real Estate Company's ability to meet its payment obligations or its financing activity, and could decrease the market prices for REITs and for properties held by such REITs.

global economy and have generally experienced slower economic growth than some less developed countries. Certain developed countries have experienced security concerns, such as terrorism and strained international relations. Incidents involving a country’s or region’s security may cause uncertainty in its markets and may adversely affect its economy and the Fund’s investments. In addition, developed countries may be adversely impacted by changes to the economic conditions of certain key trading partners, regulatory burdens, debt burdens and the price or availability of certain commodities.

Risk of Investing in Japan. The Japanese economy may be subject to considerable degrees of economic, political and social instability, which could have a negative impact on Japanese securities. Since 2000, Japan’s economic growth rate has generally remained low relative to other advanced economies, and it may remain low in the future. In addition, Japan is subject to the risk of natural disasters, such as earthquakes, volcanic eruptions, typhoons and tsunamis, which could negatively affect the Fund. Japan’s relations with its neighbors have at times been strained, and strained relations may cause uncertainty in the Japanese markets and adversely affect the overall Japanese economy.

investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Purchase and Sale of Fund Shares

The Fund is an ETF. Individual shares of the Fund are listed on a national securities exchange. Most investors will buy and sell shares of the Fund through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than at NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 100,000 shares or multiples thereof (“Creation Units”) to Authorized Participants who have entered into agreements with the Fund's distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

More Information About the Fund

substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

concerns about economic downturns or rising government debt levels in several European countries, including, but not limited to, Austria, Belgium, Cyprus, France, Greece, Ireland, Italy, Portugal, Spain and Ukraine. These events have adversely affected the exchange rate of the euro and may continue to significantly affect European countries.

Responses to financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest, may limit future growth and economic recovery or may have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. In a referendum held on June 23, 2016, the U.K. resolved to leave the EU. The referendum may introduce significant uncertainties and instability in the financial markets as the U.K. negotiates its exit from the EU. Although the precise timeframe for the U.K.’s withdrawal is uncertain, on March 29, 2017, the U.K. initiated the withdrawal process by sending a formal notice of the country’s intention to withdraw from the EU. An agreement has been reached between the U.K. and the EU to continue negotiations on the U.K.’s exit from the EU. The outcome of negotiations remain uncertain.

Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. Recently, the U.K.’s real estate sector has experienced significant volatility and declines in the value of many real estate securities, including real estate funds, REITs and real estate holding companies. Increased volatility and investor redemption requests in real estate funds may result in the continued decline in the value and liquidity of real estate securities, which may impair the ability of the Fund to buy, sell, receive or deliver those securities. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

the Index Provider’s methodology. BFA’s mandate as described in this Prospectus is to manage the Fund consistently with the Underlying Index provided by the Index Provider to BFA. BFA does not provide any warranty or guarantee against the Index Provider’s or any agent’s errors. Errors in respect of the quality, accuracy and completeness of the data used to compile the Underlying Index may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, particularly where the indices are less commonly used as benchmarks by funds or managers. Therefore, gains, losses or costs associated with errors of the Index Provider or its agents will generally be borne by the Fund and its shareholders. For example, during a period where the Underlying Index contains incorrect constituents, the Fund would have market exposure to such constituents and would be underexposed to the Underlying Index’s other constituents. Such errors may negatively or positively impact the Fund and its shareholders.

Market Trading Risk

fluctuates continuously throughout trading hours based on both market supply of and demand for Fund shares and the underlying value of the Fund's portfolio holdings or NAV. As a result, the trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV, BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long term (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs). While the creation/redemption feature is designed to make it more likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund's NAV due to timing reasons, supply and demand imbalances and other factors. In addition, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants, or other market participants, and during periods of significant market volatility, may result in trading prices for shares of the Fund that differ significantly from its NAV. Authorized Participants may be less willing to create or redeem Fund shares if there is a lack of an active market for such shares or its underlying investments, which may contribute to the Fund’s shares trading at a premium or discount to NAV.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

■	Lower levels of liquidity and market efficiency;
■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;
■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements; and

■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the U.S.

Real Estate Investment Risk. The Fund invests in Real Estate Companies, such as REITs or real estate holding companies, which expose investors to the risks of owning

real estate directly, as well as to risks that relate specifically to the way in which Real Estate Companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments and is characterized by intense competition and periodic overbuilding. Many Real Estate Companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially increase the Fund’s losses. Rising interest rates could result in higher costs of capital for Real Estate Companies, which could negatively affect a Real Estate Company's ability to meet its payment obligations or its financing activity, and could decrease the market prices for REITs and for properties held by such REITs. In addition, to the extent a Real Estate Company has its own expenses, the Fund (and indirectly, its shareholders) will bear its proportionate share of such expenses.

which means that purchase and sale transactions in those shares could have a magnified impact on share price, resulting in abrupt or erratic price fluctuations. In addition, real estate is relatively illiquid and, therefore, a Real Estate Company may have a limited ability to vary or liquidate its investments in properties in response to changes in economic or other conditions.

economic growth. A prolonged slowdown in one or more services sectors is likely to have a negative impact on economies of certain developed countries, although economies of individual developed countries can be impacted by slowdowns in other sectors. In the past, certain developed countries have been targets of terrorism, and some geographic areas in which the Fund invests have experienced strained international relations due to territorial disputes, historical animosities, defense concerns and other security concerns. These situations may cause uncertainty in the financial markets in these countries or geographic areas and may adversely affect the performance of the issuers to which the Fund has exposure. Heavy regulation of certain markets, including labor and product markets, may have an adverse effect on certain issuers. Such regulations may negatively affect economic growth or cause prolonged periods of recession. Many developed countries are heavily indebted and face rising healthcare and retirement expenses. In addition, price fluctuations of certain commodities and regulations impacting the import of commodities may negatively affect developed country economies.

Political Risk. Historically, Japan has had unpredictable national politics and may experience frequent political turnover. Future political developments may lead to changes in policy that might adversely affect the Fund’s investments. In addition, China has become an important trading partner with Japan. Japan's political relationship with China, however, is strained and delicate. Should political tension increase, it could adversely affect the Japanese economy and destabilize the region as a whole.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

the economies of Asia, Europe and the U.S. as key trading partners and investors, reduction in spending by any of these trading partners on Australasian products and services, or negative changes in any of these economies, may cause an adverse impact on some or all of the Australasian economies.

Management

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the

Fund, except the management fees, interest expenses, taxes, expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, distribution fees or expenses, litigation expenses and any extraordinary expenses (as determined by a majority of the Trustees who are not “interested persons” of the Trust).

For its investment advisory services to the Fund, BFA is paid a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.48%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Alan Mason has been employed by BFA as a portfolio manager since 1991. Mr. Mason has been a Portfolio Manager of the Fund since 2016.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

Dividends and Distributions

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to treat Fund dividends paid while the shares are held by the

borrower as qualified dividend income. In addition, you may lose the ability to use foreign tax credits passed through by the Fund if your Fund shares are loaned out pursuant to a securities lending agreement.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 100,000 shares or multiples thereof. Each “creator” or authorized participant (an “Authorized Participant”) has entered into an agreement with the Fund's distributor, BlackRock Investments, LLC (the “Distributor”), an affiliate of BFA.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Approximate Value of a Creation Unit		Creation Unit Size		Standard Creation/ Redemption Transaction Fee		Maximum Additional Charge for Creations*		Maximum Additional Charge for Redemptions*
$3,975,000		100,000		$4,500		7.0%		2.0%

*	As a percentage of the net asset value per Creation Unit, inclusive, in the case of redemptions, of the standard redemption transaction fee.

Principal Investment Strategies

The Fund seeks to track the investment results of the Morningstar^® Global ex-US Dividend Growth Index^SM (the “Underlying Index”), which is a dividend dollars weighted index that seeks to measure the performance of international equities selected based on a consistent history of growing dividends, as determined by Morningstar Inc. (the “Index Provider” or “Morningstar”). The Underlying Index is a subset of the Morningstar^® Global Markets ex-US Index^SM, which is a diversified broad market index that represents approximately 97% of the market capitalization in international developed and emerging markets, as defined by Morningstar. Eligible companies for the Underlying Index must pay a qualified dividend, must have at least five years of uninterrupted annual dividend growth and must have an earnings payout ratio of less than 75%. Companies that are in the top decile of the Morningstar Global Markets ex-US Index based on dividend yield are excluded from the Underlying Index.

The Underlying Index was comprised of stocks of companies in 40 countries as of March 31, 2018. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the consumer defensive and financials industries or sectors. The components of the Underlying Index are likely to change over time.

Summary of Principal Risks

S-3

that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes.

Consumer Defensive Industry Risk. Consumer defensive companies include companies engaged in the manufacturing of food, beverages, household and personal products, packaging, or tobacco. It also includes companies that provide services such as education and training services. Consumer defensive companies may be adversely affected by government regulation, consumers' disposable income and consumer preferences, and social trends.

Dividend-Paying Stock Risk. The Fund’s emphasis on dividend-paying stocks involves the risk that such stocks may fall out of favor with investors and underperform the broader market. Also, a company may reduce or eliminate its dividend.

The impact of changes in capital requirements and recent or future regulation of any individual financial company, or of the financials sector as a whole, cannot be predicted. In recent years, cyber-attacks and technology malfunctions and failures have become increasingly frequent in this sector and have caused significant losses to companies in this sector, which may negatively impact the Fund.

so in the future or will continue paying dividends at the same level.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

S-5

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Risk of Investing in Russia. Investing in Russian securities involves significant risks, including legal, regulatory and economic risks that are specific to Russia. In addition, investing in Russian securities involves risks associated with the settlement of portfolio transactions and loss of the Fund’s ownership rights in its portfolio securities as a result of the system of share registration and custody in Russia. A number of jurisdictions, including the U.S., Canada and the European Union (the “EU”), have imposed economic sanctions on

This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

More Information About the Fund

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on Cboe BZX Exchange, Inc. (“Cboe BZX”) (formerly known as BATS Exchange, Inc.). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Consumer Defensive Industry Risk. The Fund is subject to risks faced by companies in the consumer defensive industry, including: governmental regulation affecting the permissibility of using various food additives and production methods, which could affect profitability; new laws or litigation that may adversely affect tobacco companies; fads, marketing campaigns and other factors affecting supply and demand that may strongly affect securities prices and profitability of food, beverages and fashion related products; and international events that may affect food and beverage companies that derive a substantial portion of their net income from foreign countries.

market increases. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the Fund’s NAV may change quickly and without warning.

Dividend-Paying Stock Risk. The Fund's strategy of investing in dividend-paying stocks involves the risk that such stocks may fall out of favor with investors and underperform the broader market. Companies that issue dividend-paying stocks are not required to continue to pay dividends on such stocks. Therefore, there is the possibility that such companies could reduce or eliminate the payment of dividends in the future or the anticipated acceleration of dividends may not occur. Depending upon

market conditions, dividend-paying stocks that meet the Fund’s investment criteria may not be widely available and/or may be highly concentrated in only a few market sectors. For example, the number of issuers with annual dividend growth may decline during certain market conditions. This may limit the ability of the Fund to produce current income while remaining diversified against risks specific to such issuers or sectors.

European Economic Risk. The EU requires compliance by member states with restrictions on inflation rates, deficits, interest rates and debt levels, as well as fiscal and monetary controls, each of which may significantly affect every country in Europe, including those countries that are not members of the EU. Changes in imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro (the common currency of certain EU countries), the default or threat of default by an EU member state on its sovereign debt and/or an economic recession in an EU member state may have a significant adverse effect on the economies of EU member states and their trading partners. The European financial markets have historically experienced volatility and adverse trends due to concerns about economic downturns or rising government debt levels in several European countries, including, but not limited to, Austria, Belgium, Cyprus, France, Greece, Ireland, Italy, Portugal, Spain and Ukraine. These events have adversely affected the exchange rate of the euro and may continue to significantly affect European countries.

Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create

instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures, credit deterioration of the issuer or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline. There is no guarantee that an issuer that paid dividends in the past will continue to do so in the future or will continue paying dividends at the same level. An issuer may also be subject to risks associated with the countries, states and regions in which the issuer resides, invests, sells products, or otherwise conducts operations.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to

the risk that BFA’s investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. Market risks may be influenced by price, currency and interest rate movements. The value of a security or other asset may decline due to changes in general market conditions, economic trends or events that are not specifically related to the issuer of the security or other asset, or factors that affect a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class. During a general market downturn, multiple asset classes may be negatively affected. Changes in market conditions and interest rates generally do not have the same impact on all types of securities and instruments.

Market Trading Risk

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

■	Lower levels of liquidity and market efficiency;
■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;
■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements; and

■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the U.S.

Reliance on Trading Partners Risk. The economies of some countries or regions in which the Fund invests are dependent on trading with certain key trading partners. Reduction in spending on the products and services of these countries or regions, institution of tariffs or other trade barriers by any of their key trading partners or a

slowdown in the economies of any of their key trading partners may cause an adverse impact on the economies of such countries or regions.

■	The risk of delays in settling portfolio transactions and the risk of loss arising out of the system of share registration and custody used in Russia;
■	Risks in connection with the maintenance of the Fund’s portfolio securities and cash with foreign sub-custodians and securities depositories, including the risk that appropriate sub-custody arrangements will not be available to the Fund;
■	The risk that the Fund’s ownership rights in portfolio securities could be lost through fraud or negligence because ownership in shares of Russian companies is recorded by the companies themselves and by registrars, rather than by a central registration system; and
■	The risk that the Fund may not be able to pursue claims on behalf of its shareholders because of the system of share registration and custody, and because Russian banking institutions and registrars are not guaranteed by the Russian government.

Russia Sanctions. The U.S. and the Economic and Monetary Union of the European Union, along with the regulatory bodies of a number of countries including Japan, Australia, Norway, Switzerland and Canada (collectively, “Sanctioning Bodies”), have imposed economic sanctions, which can consist of prohibiting certain securities trades, prohibiting certain private transactions in the energy sector, asset freezes and prohibition of all business, against certain Russian individuals and Russian corporate

entities. The Sanctioning Bodies could also institute broader sanctions on Russia. These sanctions, or even the threat of further sanctions, may result in the decline of the value and liquidity of Russian securities, a weakening of the ruble or other adverse consequences to the Russian economy. These sanctions could also result in the immediate freeze of Russian securities and/or funds invested in prohibited assets, impairing the ability of the Fund to buy, sell, receive or deliver those securities and/or assets. Additional sanctions against Russia have been, and may in the future be, imposed by the U.S. or other countries.

fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Borrowing Risk. Borrowing may exaggerate changes in the net asset value of Fund shares and in the return on the Fund’s portfolio. Borrowing will cost the Fund interest expense and other fees. The costs of borrowing may reduce the Fund’s return. Borrowing may also cause the Fund to liquidate positions when it may not be advantageous to do so to satisfy its obligations.

Consumer Cyclical Industry Risk. The success of consumer cyclical companies is tied closely to the performance of domestic and international economies, exchange rates, interest rates, competition, consumer confidence, changes in demographics and preferences. Companies in the consumer cyclical industry sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

Technology Sector Risk. Technology companies, including information technology companies, face intense competition, both domestically and internationally, which may

have an adverse effect on a company’s profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector are heavily dependent on patent and other intellectual property rights. A technology company’s loss or impairment of these rights may adversely affect the company’s profitability.

Dividends and Distributions

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. Distributions in excess of the Fund’s minimum distribution requirements, but not in excess of the Fund’s earnings and profits, will be taxable to shareholders and will not constitute nontaxable returns of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder's cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P International Preferred Stock Index^TM (the “Underlying Index”), which measures the performance of a select group of preferred stocks from non-U.S. developed market issuers and traded on non-U.S. developed market exchanges as defined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”), a subsidiary of S&P Global, Inc. Securities listed in emerging markets are excluded. Preferred stock, unlike common stock, does not as directly reflect the performance of the common stock of companies issuing the preferred stock. The Underlying Index includes developed-market preferred stocks with a market capitalization over $100 million that meet minimum liquidity, trading volume, maturity and other requirements determined by the sponsor of the Underlying Index. The Underlying Index excludes certain issues of preferred stock, such as those that are issued by special ventures (e.g., toll roads or dam operators) or structured products that are linked to

indexes or other stocks.

In general, preferred stock is a class of equity security that pays a specified dividend that must be paid before any dividends can be paid to common stockholders and takes precedence over common stock in the event of a company’s liquidation.

Although preferred stocks represent a partial ownership interest in a company, preferred stocks generally do not carry voting rights and have economic characteristics similar to fixed-income securities. Preferred stocks generally are issued with a fixed par value and pay dividends based on a percentage of that par value at a fixed or variable rate. Additionally, preferred stocks often have a liquidation value that generally equals the original purchase price of the preferred stock at the date of issuance. The Underlying Index may include many different categories of preferred stock, such as floating, variable and fixed-rate preferreds, callable preferreds, convertible preferreds, cumulative and non-cumulative preferreds or various other traditional and hybrid issues of preferred stock.

As of March 31, 2018, the Underlying Index was comprised of stocks of companies in the following countries: Canada, Singapore, Spain, Sweden and the United Kingdom (the “U.K.”). The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the energy and financials industries or sectors. The components of the Underlying Index are likely to change over time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s

S-2

cash equivalents, including shares of money market funds advised by BFA or its affiliates, as well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

industry, group of industries, sector or asset class.

Energy Sector Risk. The market value of securities in the energy sector may decline for many reasons, including, among others, changes in energy prices,

S-4

energy supply and demand, government regulations and energy conservation efforts.

Equity Securities Risk. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. The Underlying Index includes preferred stocks, holders of which generally are subject to more risks than debt securities because preferred stockholders’ claims are subordinated to those of holders of debt securities upon the bankruptcy of the issuer.

Financials Sector Risk. Performance of companies in the financials sector may be adversely impacted by many factors, including, among others, changes in government regulations, economic conditions, and interest rates, credit rating downgrades, and decreased liquidity in credit markets. The extent to which the Fund may invest in a company that engages in securities-related activities or banking is limited by applicable law. A fund that invests in preferred securities may be more likely to be impacted by such legal limits since companies in the financials sector have historically issued a significant portion of the preferred securities marketplace. The impact of changes in capital requirements and recent or future regulation of any individual financial company, or of the financials sector as a whole, cannot be predicted. In recent years, cyber-attacks and technology malfunctions and failures have become increasingly frequent in this sector and have caused significant losses to companies in this sector, which may negatively impact the Fund.

Geographic Risk. A natural disaster could occur in a geographic region in which the Fund invests, which could

adversely affect the economy or the business operations of companies in the specific geographic region, causing an adverse impact on the Fund's investments in the affected region.

Interest Rate Risk. An increase in interest rates may cause the value of securities held by the Fund to decline, may lead to heightened volatility in the preferred securities market and may adversely affect the liquidity of certain preferred investments. The historically low interest rate environment, together with recent modest rate increases, heightens the risks associated with rising interest rates.

Large-Capitalization Companies Risk. Large-capitalization companies may be less able than smaller capitalization

S-5

companies to adapt to changing market conditions. Large-capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large-capitalization companies has trailed the overall performance of the broader securities markets.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

NAV that may be greater than those experienced by other ETFs.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Preferred Stock Risk. Preferred stocks are subject not only to issuer-specific

S-6

and market risks generally applicable to equity securities, but also risks associated with fixed-income securities, such as interest rate risk. A company’s preferred stock, which may pay fixed or variable rates of return, generally pays dividends only after the company makes required payments to creditors, including vendors, depositors, counterparties, holders of its bonds and other fixed-income securities. As a result, the value of a company’s preferred stock will react more strongly than bonds and other debt to actual or perceived changes in the company’s financial condition or prospects. Preferred stock may be less liquid than many other types of securities, such as common stock, and generally has limited or no voting rights. In addition, preferred stock is subject to the risks that a company may defer or not pay dividends, and, in certain situations, may call or redeem its preferred stock or convert it to common stock. An issuer may decide to call its outstanding preferred stock in various environments based on its assessment of the relative cost of capital across the company’s capital structure. A market-wide increase in preferred stock being called may reduce the aggregate size of the preferred stock universe and the number of issuers with preferred stock outstanding. Such reductions may make it more challenging for the Fund to invest in the component securities of the Underlying Index, increasing the risk of the Fund being underinvested in the Underlying Index and thus increasing the risk of tracking error. To the extent that the Fund invests a substantial portion of its assets in convertible preferred stocks, declining common stock values may also cause the value of the Fund’s investments to decline.

Risk of Investing in Canada. Investments in Canadian issuers may subject the Fund to economic risk specific to Canada. Among other things, the Canadian economy is heavily

dependent on relationships with certain key trading partners, including the U.S. and China. The Canadian economy is sensitive to fluctuations in certain commodity markets.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes. The Underlying Index includes preferred stocks, holders of which generally are subject to more risks than debt securities because preferred stockholders’ claims are subordinated to those of holders of debt securities upon the bankruptcy of the issuer.

Financials Sector Risk. Companies in the financials sector of an economy are subject to extensive governmental regulation and intervention, which may adversely affect the

scope of their activities, the prices they can charge, the amount of capital they must maintain and, potentially, their size. The extent to which the Fund may invest in a company that engages in securities-related activities or banking is limited by applicable law. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financials sector, including effects not intended by such regulation. Recently enacted legislation in the U.S. has relaxed capital requirements and other regulatory burdens on certain U.S. banks. While the effect of the legislation may benefit certain companies in the financials sector, increased risk taking by affected banks may also result in greater overall risk in the financials sector. The impact of changes in capital requirements, or recent or future regulation in various countries, on any individual financial company or on the financials sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financials sector more severely than those of investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financials sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Insurance companies, in particular, may be subject to severe price competition and/or rate regulation, which may have an adverse impact on their profitability. The financials sector is particularly sensitive to fluctuations in interest rates. The banking industry, in particular, is negatively affected by interest rates when they remain low for long periods of time as banks are more profitable when there is a larger spread between the federal funds rate and what depositories pay in interest. The financials sector is also a target for cyber attacks, and may experience technology malfunctions and disruptions. In recent years, cyber attacks and technology malfunctions and failures have become increasingly frequent in this sector and have reportedly caused losses to companies in this sector, which may negatively impact the Fund.

the security or other asset, or factors that affect a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class. During a general market downturn, multiple asset classes may be negatively affected. Changes in market conditions and interest rates generally do not have the same impact on all types of securities and instruments.

Market Trading Risk

MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV, BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long term (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs). While the creation/redemption feature is designed to make it more likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund's NAV due to timing reasons, supply and demand imbalances and other factors. In addition, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants, or other market participants, and during periods of significant market volatility, may result in trading prices for shares of the Fund that differ significantly from its NAV. Authorized Participants may be less willing to create or redeem Fund shares if there is a lack of an active market for such shares or its underlying investments, which may contribute to the Fund’s shares trading at a premium or discount to NAV.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks of investing in the markets where such issuers are located,

including heightened risks of inflation, nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

■	Lower levels of liquidity and market efficiency;
■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;
■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements; and

■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the U.S.

Preferred Stock Risk. Unlike interest payments on a debt security, dividend payments on preferred stock typically must be declared by the issuer's board of directors. An issuer's board of directors is generally not under any obligation to pay dividends (even if such dividends have accrued), and may suspend payment of dividends on preferred stock at any time. In the event an issuer of preferred stock experiences economic difficulties, the issuer's preferred stock may lose substantial value due to the reduced likelihood that the issuer's board of directors will declare dividends and the fact that the preferred stock may be subordinated to other securities of the same issuer. Certain additional risks associated with preferred stock could adversely affect investments in the Fund.

Interest Rate Risk. Because many preferred stocks pay dividends at a fixed rate, their market price can be sensitive to changes in interest rates in a manner similar to bonds. That is, as interest rates rise, the value of the preferred stocks held by the Fund are likely to decline. To the extent that the Fund invests a substantial portion of its assets in fixed rate preferred stocks, rising interest rates may cause the value of the Fund's investments to decline significantly.

Issuer Risk. Because many preferred stocks allow holders to convert the preferred stock into common stock of the issuer, market price of a preferred stock can be sensitive to changes in the value of the issuer's common stock. To the extent that the Fund invests a substantial portion of its assets in convertible preferred stocks, declining common stock values may also cause the value of the Fund's investments to decline.

Dividend Risk. There is a chance that the ability to pay dividends by the issuer of a preferred stock held by the Fund may deteriorate or the issuer may default (i.e., fail to make scheduled dividend payments on the preferred stock or scheduled interest payments on other obligations of the issuer not held by the Fund), which would negatively affect the value of any such holding.

Call Risk. Preferred stocks are subject to market volatility, and the prices of preferred stocks will fluctuate based on market demand. Preferred stocks often have call features that allow the issuer to redeem the security at its discretion. If a preferred stock is redeemed by the issuer, it will be removed from the Underlying Index. The redemption of preferred stocks having a higher than average yield may cause a decrease in the yield of the Underlying Index and the Fund. Because the Underlying Index is rebalanced annually, the removal of a large number of preferred stocks during the year due to maturity, redemption, conversion or other corporate action may cause the Underlying Index to be periodically concentrated in a smaller number of issuers or in issuers of a particular sector or industry.

Extension Risk. During periods of rising interest rates, certain obligations will be paid off substantially more slowly than originally anticipated, and the value of those securities may fall sharply, resulting in a decline to the Fund’s income and potentially in the value of the Fund’s investments.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

European Economic Risk. The European Union (“EU”) requires compliance by member states with restrictions on inflation rates, deficits, interest rates and debt levels, as well as fiscal and monetary controls, each of which may significantly affect every country in Europe, including those countries that are not members of the EU. Changes in imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro (the common currency of certain EU countries), the default or threat of default by an EU member state on its sovereign debt and/or an economic recession in an EU member state may have a significant adverse effect on the economies of EU member states and their trading partners. The European financial markets have historically experienced volatility and adverse trends due to concerns about economic downturns or rising government debt levels in several European countries, including, but not limited to, Austria, Belgium, Cyprus, France, Greece, Ireland, Italy, Portugal, Spain and Ukraine. These events have adversely affected the exchange rate of the euro and may continue to significantly affect European countries.

Responses to financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest, may limit future growth and economic recovery or may have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. In a referendum held on June 23, 2016, the U.K. resolved to leave the EU. The referendum may introduce significant uncertainties and instability in the financial markets as the U.K. negotiates its exit from the EU. Although the precise timeframe for the U.K.’s withdrawal is uncertain, on March 29, 2017, the U.K. initiated the withdrawal process by sending a formal notice of the country’s intention to withdraw from the EU. An agreement has been reached between the U.K. and the EU to continue negotiations on the U.K.’s exit from the EU. The outcome of negotiations remain uncertain.

Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

Real Estate Investment Risk. The Fund may invest in Real Estate Companies, such as real estate investment trusts (“REITs”) or real estate holding companies, which expose investors to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which Real Estate Companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments and is characterized by intense competition and periodic overbuilding. Many Real Estate Companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially increase the Fund’s losses. Rising interest rates could result in higher costs of capital for Real Estate Companies, which could negatively affect a Real Estate Company's ability to meet its payment obligations or its financing activity, and could decrease the market prices for REITs and for properties held by such REITs. In addition, to the extent a Real Estate Company has its own expenses, the Fund (and indirectly, its shareholders) will bear its proportionate share of such expenses.

Repayment Risk. The prices of Real Estate Company securities may drop because of the failure of borrowers to repay their loans, poor management, or the inability to

affected by the relevant threshold limits, and such limitations may have adverse effects on the liquidity and performance of the Fund’s portfolio holdings compared to the performance of the Underlying Index. This may increase the risk of the Fund being underinvested to the Underlying Index and increase the risk of tracking error.

Management

For its investment advisory services to the Fund, BFA is paid a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.55%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

BFA has entered into a sub-advisory agreement with the Sub-Adviser, an affiliate of BFA, under which BFA pays the Sub-Adviser for services it provides either: (i) a fee equal to a percentage of the management fee paid to BFA under the Investment Advisory Agreement or (ii) an amount based on the cost of the services provided. The Sub-Adviser, subject to the supervision and oversight of the Trust's Board of Trustees (the “Board”) and BFA, will be primarily responsible for execution of securities transactions outside the U.S. and Canada and may, from time to time, participate in the management of specified assets in the Fund’s portfolio. If the Sub-Adviser provides services relating to both portfolio management and trading, it is entitled to receive from BFA an amount equal to 20% of BFA’s management fee, and if the Sub-Adviser

provides services related solely to trading, then it is entitled to receive from BFA an amount equal to 110% of the actual pre-tax costs incurred by the Sub-Adviser.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is an indirect wholly-owned subsidiary of BlackRock, Inc. (“BlackRock”). As of June 30, 2018, BFA and its affiliates provided investment advisory services for assets in excess of $6.29 trillion. BIL is an investment adviser located in the U.K. at Exchange Place One, 1 Semple Street, Edinburgh EH3 8BL, Scotland 011 44 131 472 7200. The Sub-Adviser is a registered investment adviser and a commodity pool operator organized in 1999. As of June 30, 2017, the Sub-Adviser’s total assets under management were approximately $16.41 billion. BFA, the Sub-Adviser, and their affiliates trade and invest for their own accounts in the actual securities and types of securities in which the Fund may also invest, which may affect the price of such securities.

A discussion regarding the basis for the approval by the Board of the Investment Advisory Agreement with BFA and the sub-advisory agreement between BFA and the Sub-Adviser is available in the Fund's semi-annual report for the period ended September 30.

Alan Mason has been employed by BFA as a portfolio manager since 1991. Mr. Mason has been a Portfolio Manager of the Fund since 2016.

Amy Whitelaw has been with BlackRock since 1999, including her years with BGI, which merged with BlackRock in 2009. Ms. Whitelaw has been employed by BFA or its

As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Dividends and Distributions

Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the U.S., which includes an exchange of information program, or if the stock with respect to which the dividend was paid is readily tradable on an established U.S. securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. Distributions in excess of the Fund’s minimum distribution requirements, but not in excess of the Fund’s earnings and profits, will be taxable to shareholders and will not constitute nontaxable returns of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder's cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in

block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or authorized participant (an “Authorized Participant”) has entered into an agreement with the Fund's distributor, BlackRock Investments, LLC (the “Distributor”), an affiliate of BFA.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Principal Investment Strategies

The Japan Exchange Group, Inc. and Tokyo Stock Exchange, Inc. (“TSE”) (collectively referred to as the “JPX Group”) and Nikkei Inc. (the “Nikkei”) are the Fund’s index providers (collectively, the “Index Provider”). The Fund seeks to track the investment results of the JPX-Nikkei Index 400 (the “Underlying Index”), which is comprised of (i) common stocks whose main market is the TSE First Section, TSE Second Section, Mothers, or JASDAQ Securities Exchange (“JASDAQ”) and (ii) securities listed on TSE First Section, TSE Second Section, Mothers or JASDAQ that are not common stocks but are regarded by the Index Provider as equivalent to common stocks, in each case if the inclusion in the Underlying Index is deemed to be “particularly necessary” as determined by the Index Provider.

Companies deemed “particularly necessary” refer to companies that the Index Provider determines to have high appeal for investors and to meet requirements of global investment standards, such as efficient use of

capital and investor-focused management perspectives. The currency of the component securities of the Underlying Index is the Japanese yen (“JPY”). The calculations of returns of the Underlying Index from JPY to U.S. dollars (“USD”) are provided independently by S&P Dow Jones Indices LLC.

The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the consumer discretionary and industrials industries or sectors.

selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of an applicable underlying index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

S-3

risk may be heightened for exchange-traded funds (“ETFs”), such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes.

Currency Risk. Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if the Yen depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the Fund's NAV may change quickly and without warning.

and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cyber security plans and systems of the Fund’s service providers, the Index Provider, market makers, Authorized Participants or issuers of securities in which the Fund invests.

S-4

time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders.

Lack of Natural Resources Risk. The Fund invests in Japanese companies. Japan has few natural resources and is reliant on imports for its commodity needs. Any fluctuation or shortage in the commodity markets could have a negative impact on the Japanese economy.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's

investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or

S-5

nationalization. The Fund may lose money due to political, economic and geographic events affecting issuers of non-U.S. securities or non-U.S. markets. In addition, non-U.S. securities markets may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times. The Fund is specifically exposed to Asian Economic Risk.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Reliance on Trading Partners Risk. The Fund invests in Japan, which is heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund's investments. Through its portfolio companies' trading partners, the Fund and the Underlying Fund are specifically exposed to Asian Economic Risk, European Economic Risk and U.S. Economic Risk.

Security Risk. Japan has experienced security concerns, such as terrorism and strained international relations. Incidents involving Japan's or the region's security may cause uncertainty in Japanese markets and may adversely affect the Japanese economy and the Fund's investments.

Tracking Error Risk. The Fund may be subject to tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur because of

S-6

differences between the securities and other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences (including, as applicable, differences between a security’s price at the local market close and the Fund's valuation of a security at the time of calculation of the Fund's NAV), differences in transaction costs, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or interest, tax gains or losses, differences between the Underlying Index’s assumptions for the foreign withholding tax rate for dividends and the rate incurred by the Fund, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

Valuation Risk. The price the Fund could receive upon the sale of a security

Performance Information

The bar chart and table that follow show how the Fund has performed on a calendar year basis and provide an indication of the risks of investing in the Fund. Both assume that all dividends and distributions have been reinvested in the Fund. Two versions of the Underlying Index are calculated by the Index Provider-(i) the total return index, which is calculated including dividends with no tax withholding, and (ii) the net total return index, namely, the JPX-Nikkei Index 400 (the “Net Total Return Index”), which is the index that underlies the Fund. The Net Total Return Index is calculated including dividends but withholds taxes based on the maximum withholding tax rates applicable to dividends received by non-resident investors. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Supplemental information about the Fund’s performance is shown under the heading Total Return Information in the Supplemental Information section of the Prospectus.

Year-by-Year Returns¹(Years Ended December 31)

¹	The Fund’s year-to-date return as of June 30, 2018 was -2.29%.

The best calendar quarter return during the periods shown above was 22.63% in the 2nd quarter of 2009; the worst was -17.71% in the 3rd quarter of 2008.

	One Year	Five Years	Ten Years
(Inception Date: 10/23/2001)
Return Before Taxes	24.01%	10.82%	2.68%
Return After Taxes on Distributions¹	23.70%	10.58%	2.50%
Return After Taxes on Distributions and Sale of Fund Shares¹	14.09%	8.71%	2.21%
JPX-Nikkei Index 400 (Index returns do not reflect deductions for fees, expenses, or taxes)²	24.48%	11.27%	2.99%

After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sales of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares in cases where the shares have decreased in value during the period. As a result, Fund returns after taxes on distributions and sales of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

²	Index returns through September 3, 2015 reflect the performance of the S&P/TOPIX 150^TM. Index returns beginning on September 4, 2015 reflect the performance of the JPX-Nikkei Index 400, which, effective as of September 4, 2015, replaced the S&P/TOPIX 150 as the underlying index of the Fund.

Purchase and Sale of Fund Shares

The Fund is an ETF. Individual shares of the Fund are listed on a national securities exchange. Most investors will buy and sell shares of the Fund through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than at NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 150,000 shares or multiples thereof (“Creation Units”) to Authorized Participants who have entered into agreements with the Fund's distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

More Information About the Fund

substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Currency Risk. Because the Fund's NAV is determined on the basis of the U.S. dollar, investors may lose money if the Yen depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency, even if such currency value of the Fund's holdings in that market increases. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the Fund’s NAV may change quickly and without warning.

the Fund’s investment in such portfolio companies to lose value. Unlike many other types of risks faced by the Fund, these risks typically are not covered by insurance. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber incidents include, but are not limited to, gaining unauthorized access to digital systems (e.g., through “hacking” or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cyber attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make network services unavailable to intended users). Cyber security failures by or breaches of the systems of the Fund’s adviser, distributor and other service providers (including, but not limited to, index providers, fund accountants, custodians, transfer agents and administrators), market makers, Authorized Participants or the issuers of securities in which the Fund invests, have the ability to cause disruptions and impact business operations, potentially resulting in: financial losses, interference with the Fund’s ability to calculate its NAV, disclosure of confidential trading information, impediments to trading, submission of erroneous trades or erroneous creation or redemption orders, the inability of the Fund or its service providers to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. In addition, cyber attacks may render records of Fund assets and transactions, shareholder ownership of Fund shares, and other data integral to the functioning of the Fund inaccessible or inaccurate or incomplete. Substantial costs may be incurred by the Fund in order to resolve or prevent cyber incidents in the future. While the Fund has established business continuity plans in the event of, and risk management systems to prevent, such cyber attacks, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified and that prevention and remediation efforts will not be successful. Furthermore, the Fund cannot control the cyber security plans and systems put in place by service providers to the Fund, issuers in which the Fund invests, the Index Provider, market makers or Authorized Participants. The Fund and its shareholders could be negatively impacted as a result.

and/or an economic recession in an EU member state may have a significant adverse effect on the economies of EU member states and their trading partners. The European financial markets have historically experienced volatility and adverse trends due to concerns about economic downturns or rising government debt levels in several European countries, including, but not limited to, Austria, Belgium, Cyprus, France, Greece, Ireland, Italy, Portugal, Spain and Ukraine. These events have adversely affected the exchange rate of the euro and may continue to significantly affect European countries.

Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

Lack of Natural Resources Risk. Japan is an island state with few natural resources and limited land area. Japan is reliant on imports for its commodity needs. Any fluctuations or shortages in the commodity markets would have a material impact on the Japanese economy.

Market Trading Risk

discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

■	Lower levels of liquidity and market efficiency;
■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;
■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements; and

■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the U.S.

Reliance on Trading Partners Risk. The Japanese economy is heavily dependent on international trade and has been adversely affected by trade tariffs, other protectionist measures and rising commodity prices. Japanese economic growth has been dependent on the U.S. and Chinese economies, with trade increasing with China in recent years.

Political Risk. Historically, Japan has had unpredictable national politics and may experience frequent political turnover. Future political developments may lead to changes in policy that might adversely affect the Fund’s investments. In addition, China has become an important trading partner with Japan. Japan's political relationship with China, however, is strained and delicate. Should political tension increase, it could adversely affect the Japanese economy and destabilize the region as a whole.

markets could cause the value of the yen to fluctuate sharply and unpredictably and could cause losses to investors.

Security Risk. Japan has experienced acts of terrorism, strained international relations due to territorial disputes, historical animosities and other defense concerns. These situations may cause uncertainty in the Japanese market and may adversely affect the performance of the Japanese economy.

subject to foreign withholding tax on dividends paid on foreign securities, the Fund may incur a withholding tax rate that is different from the rate assumed by the “net” version of the Underlying Index due to any applicable tax treaty between the U.S. and such foreign governments. If the actual withholding tax rate incurred by the Fund is lower than the rate assumed by the Index Provider, the stated performance of the Underlying Index will be understated relative to the Fund.

U.S. Economic Risk. The U.S. is a significant trading partner of Japan. As a result, economic conditions of Japan may be particularly affected by changes in the U.S. economy. For example, a decrease in U.S. imports, new trade and financial regulations, changes in the U.S. dollar exchange rate or an economic slowdown in the U.S. may have a material adverse effect on the economic conditions of Japan and, as a result, securities to which the Fund has exposure.

Valuation Risk. The price the Fund could receive upon the sale of a security or other asset may differ from the Fund's valuation of the security or other asset and from the value used by the Underlying Index, particularly for securities or other assets that trade in low volume or volatile markets or that are valued using a fair value methodology as a result of trade suspensions or for other reasons. Because Japanese exchanges may be open on days when the Fund does not price its shares, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund's NAV, the value of assets denominated in Yen is converted into U.S. dollars using prevailing market rates on the date of valuation as quoted by one or more data service providers. This conversion may result in a difference between the prices used to calculate the Fund's NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund's performance and the performance of the Underlying Index. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

this trend toward consolidation are unknown and may be far-reaching. Many healthcare companies are heavily dependent on patent protection. The expiration of a company’s patents may adversely affect that company’s profitability. Many healthcare companies are subject to extensive litigation based on product liability and similar claims. Healthcare companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the healthcare sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly, and such efforts ultimately may be unsuccessful. Companies in the healthcare sector may be thinly capitalized and may be susceptible to product obsolescence. In addition, a number of legislative proposals concerning healthcare have been considered by the U.S. Congress in recent years. It is unclear what proposals will ultimately be enacted, if any, and what effect they may have on companies in the healthcare sector.

iSHARES^® LATIN AMERICA 40 ETF

Ticker: ILF

Stock Exchange: NYSE Arca

S-1

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P Latin America 40^TM (the “Underlying Index”), which is comprised of selected equities trading on the exchanges of five Latin American countries. The Underlying Index includes securities that S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”), a subsidiary of S&P Global, Inc., considers to be highly liquid from major economic sectors of the Mexican and South American equity markets. Companies from Brazil, Chilé, Colombia, Mexico and Peru are represented in the Underlying Index. The Underlying Index includes large blue-chip companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the financials and materials industries or sectors. The components of the Underlying Index are likely to change over time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and

does not seek temporary defensive positions when markets decline or appear overvalued.

results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

Asset Class Risk. Securities and other assets in the Underlying Index or in the Fund's portfolio may underperform in comparison to the general financial

markets, a particular financial market or other asset classes.

Commodity Risk. The Fund invests in companies that are susceptible to fluctuations in certain commodity markets and to price changes due to trade relations, including the imposition of tariffs by the U.S. and other importing countries. Any negative changes in commodity markets that may be due to changes in supply and demand for commodities, market events, regulatory developments or other factors that the Fund cannot control could have an adverse impact on those companies.

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events

S-3

that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class.

Participants or issuers of securities in which the Fund invests.

Geographic Risk. A natural disaster could occur in Latin America or another market in which the Fund invests, which could adversely affect the economies of those regions, causing an adverse impact on the Fund.

S-4

disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

S-5

specifically exposed to Latin American Economic Risk.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Risk of Investing in Brazil. Investment in Brazilian issuers involves risks that are specific to Brazil, including legal, regulatory, political and economic risks. The Brazilian economy has historically been exposed to high rates of inflation and a high level of debt, each of which

may reduce and/or prevent economic growth.

Risk of Investing in Latin America. The economies of certain Latin American countries have experienced high interest rates, economic volatility, inflation, currency devaluations, government debt defaults and high unemployment rates. Certain Latin American countries have experienced periods of political and economic instability and social unrest in the past. International economic conditions, particularly those in the U.S., Europe and Asia, as well as world prices for oil and other commodities may also influence the development of Latin American economies. These risks, among others, may adversely affect the value of the Fund’s investments.

Risk of Investing in Mexico. Investments in Mexican issuers involve risks that are specific to Mexico, including legal, regulatory, political, currency, security and economic risks. In the past, Mexico has experienced high interest rates, economic volatility and high unemployment rates. Recent political developments in the U.S. have potential implications for the current trade arrangements between the U.S. and Mexico, which could negatively affect the value of securities held by the Fund.

S-6

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Purchase and Sale of Fund Shares

The Fund is an ETF. Individual shares of the Fund are listed on a national securities exchange. Most investors will buy and sell shares of the Fund through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than at NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 250,000 shares or multiples thereof (“Creation Units”) to Authorized Participants who have entered into agreements with the Fund's distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

More Information About the Fund

substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

are subject to social and labor risks associated with demands for improved political, economic and social conditions. These risks, among others, may adversely affect the value of the Fund’s investments.

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

applicable law. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financials sector, including effects not intended by such regulation. Recently enacted legislation in the U.S. has relaxed capital requirements and other regulatory burdens on certain U.S. banks. While the effect of the legislation may benefit certain companies in the financials sector, increased risk taking by affected banks may also result in greater overall risk in the financials sector. The impact of changes in capital requirements, or recent or future regulation in various countries, on any individual financial company or on the financials sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financials sector more severely than those of investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financials sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Insurance companies, in particular, may be subject to severe price competition and/or rate regulation, which may have an adverse impact on their profitability. The financials sector is particularly sensitive to fluctuations in interest rates. The financials sector is also a target for cyber attacks, and may experience technology malfunctions and disruptions. In recent years, cyber attacks and technology malfunctions and failures have become increasingly frequent in this sector and have reportedly caused losses to companies in this sector, which may negatively impact the Fund.

example, during a period where the Underlying Index contains incorrect constituents, the Fund would have market exposure to such constituents and would be underexposed to the Underlying Index’s other constituents. Such errors may negatively or positively impact the Fund and its shareholders.

Latin American Economic Risk. The economies of certain Latin American countries have experienced high interest and inflation rates, economic volatility, currency devaluations, government defaults and high unemployment rates. In addition, commodities (such as oil, gas and minerals) represent a significant percentage of the region’s exports, and many economies in this region are particularly sensitive to fluctuations in commodity prices. The economies of Latin American countries are heavily dependent on trading relationships with key trading partners, including the U.S., Europe, Asia and other Latin American countries. Adverse economic events in one country may have a significant adverse effect on other countries of this region. In addition, in the past, certain Latin American economies have been influenced by changing supply and demand for a particular currency, monetary policies of governments (including exchange control programs, restrictions on local exchanges or markets and limitations on foreign investment in a country or on investment by residents of a country in other countries), and currency devaluations and revaluations.

For example, the government of Brazil imposes a tax on foreign investment in Brazilian stocks and bonds, which may affect the value of the Fund's investments in the securities of Brazilian issuers.

■	Structural Risk. Certain Latin American countries are subject to a considerable degree of economic, political and social instability, which could adversely affect investments in the Fund.
■	Economic Risk. Certain Latin American countries have experienced economic instability resulting from periods of high inflation and currency devaluations.
■	Political and Social Risk. Certain Latin American countries have experienced periods of instability and social unrest in the past. For example, Mexico has been destabilized by local insurrections, social upheavals and drug related violence. Disparities of wealth, the pace and success of democratization and capital market development and ethnic, religious and racial disaffection may exacerbate social unrest, violence and labor unrest in a number of Latin American countries. Certain Latin American countries experience significant unemployment in certain regions, as well as widespread underemployment.

Market Trading Risk

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

■	Lower levels of liquidity and market efficiency;
■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;
■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;

■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements; and

■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the U.S.

Risk of Investing in Brazil. Investment in Brazilian issuers involves risks that are specific to Brazil, including legal, regulatory, political, currency and economic risks. Specifically, Brazilian issuers are subject to possible regulatory and economic interventions by the Brazilian government, including the imposition of wage and price controls and the limitation of imports. In addition, the market for Brazilian securities is directly influenced by the flow of international capital and economic and market conditions of certain countries, especially other emerging market countries in Central and South America. The Brazilian economy has historically been exposed to high rates of inflation and a high level of debt, each of which may reduce and/or prevent economic growth. A rising unemployment rate could also have the same effect.

Risk of Investing in Mexico. Investment in Mexican issuers involves risks that are specific to Mexico, including regulatory, political, and economic risks. The Mexican economy is dependent upon external trade with other economies, specifically with the U.S. and certain Latin American countries. As a result, Mexico is dependent on, among other things, the U.S. economy and any change in the price or demand for Mexican exports may have an adverse impact on the Mexican economy. For example, lower oil prices have negatively impacted Petróleos Mexicanos, the Mexican State-owned petroleum company, which accounts for a significant percentage of the Mexican government's tax revenue. Recently, Mexico has experienced adverse economic impacts as a result of earthquakes and hurricanes, as well as outbreaks of violence. Incidents involving Mexico’s security may have an adverse effect on the Mexican economy and cause uncertainty in its financial markets. In the past, Mexico has experienced high interest rates, economic volatility and high unemployment rates.

Political and Social Risk. Disparities of wealth, the pace and success of democratization

and ethnic, religious and racial disaffection, among other factors, may exacerbate social unrest, violence and labor unrest in some of the countries in which the Fund may invest. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.

Large Government Debt Risk. Chronic structural public sector deficits in some countries in which the Fund may invest may adversely impact securities held by the Fund.

other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund's NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using prevailing market rates on the date of valuation as quoted by one or more data service providers. This conversion may result in a difference between the prices used to calculate the Fund's NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund's performance and the performance of the Underlying Index. Authorized Participants who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received had the Fund not fair-valued securities or used a different valuation methodology. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Management

and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

For its investment advisory services to the Fund, BFA is paid a management fee from the Fund calculated based on the aggregate average daily net assets of the following iShares funds: iShares Latin America 40 ETF, iShares MSCI Pacific ex Japan ETF, iShares Russell 2000 ETF, iShares Russell 2000 Growth ETF, iShares Russell 2000 Value ETF, iShares Select Dividend ETF and iShares U.S. Preferred Stock ETF. The management fee for the Fund equals the ratio of the Fund's net assets over the aggregate net assets of the above iShares funds multiplied by the amount calculated as follows: 0.5000% per annum of the aggregate net assets less than or equal to $46 billion, plus 0.4750% per annum of the aggregate net assets over $46 billion, up to and including $81 billion, plus 0.4513% per annum of the aggregate net assets over $81 billion, up to and including $111 billion, plus 0.4287% per annum of the aggregate net assets over $111 billion, up to and including $141 billion, plus 0.4073% of the aggregate net assets in excess of $141 billion. Based on the assets of the iShares funds listed above as of March 31, 2018, for its investment advisory services to the Fund, BFA was paid a management fee from the Fund, as a percentage of the Fund's average daily net assets, at the annual rate of 0.48%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Alan Mason has been employed by BFA as a portfolio manager since 1991. Mr. Mason has been a Portfolio Manager of the Fund since 2016.

Non-U.S. securities whose values are affected by volatility that occurs in the local markets or in related or highly correlated assets (e.g., American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) or substantially identical ETFs) on a trading day after the close of non-U.S. securities markets may be fair valued.

Dividends and Distributions

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general

information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

Brazilian Tax Disclosure. With respect to Brazil, the following transactions are potentially subject to the “IOF” tax (Imposto sobre Operacões Financeiras), but the current tax rate for all of them is presently reduced to zero: (i) foreign currency exchange (“FX”) transactions entered into in connection to the inflow of funds into Brazil for investments of non-Brazilian residents in the Brazilian financial and capital markets, including investments in publicly traded shares (equities/stocks), other types of securities traded on Brazilian exchanges or organized over-the-counter markets, futures contracts, options, swaps, investments in local funds, and other fixed or variable income investments; (ii) assignment of Brazilian equities with the specific purpose of backing issuances (creation) of new depositary receipts (ADRs or GDRs)

with respect to Brazilian equities; (iii) FX transactions entered into in connection with symbolic inflows of funds into Brazil due to cancellation of ADRs or GDRs and consequent foreign investment in the underlying Brazilian equities; and (iv) FX transactions entered into in connection with outflows for return (repatriation) of funds invested by foreign residents in the Brazilian financial and capital markets, including investments in Brazilian equities, other types of securities traded on Brazilian exchanges or organized over-the-counter markets, futures contracts, options, swaps, investments in local funds, and other fixed or variable income investments. Transactions involving certain types of securities may, however, be subject to a non-zero IOF, depending upon the securities negotiated, term of the investment, parties involved and other variables.

Current IOF rates are lower than their legal limits, but rates may be increased or reduced by the Brazilian federal government via executive decree at any time, regardless of Brazilian congressional approval, up to the limits set forth by law. Changes in IOF rates are immediately applicable to new transactions. The maximum rates of IOF on FX transactions and of IOF on transactions with securities are, respectively, legally limited to 25% of the amount of the FX transaction and 1.5% per day of the amount of the transaction with securities. If incurred by the Fund, an IOF tax would not be creditable against U.S. income tax liability.

Provided that the Fund invests in Brazilian equities in accordance with the terms and conditions set forth by Resolution No. 4.373, of September 29, 2014, from the Brazilian Monetary Council (“CMN”), and is not domiciled in a tax haven jurisdiction (as defined by Brazilian legislation, which does not include the U.S.), capital gains earned by the Fund upon dispositions of Brazilian equities within Brazilian exchanges shall be exempt from Brazilian Income Tax. Dividends stemming from such equity investments are also currently exempt from Brazilian Withholding Income Tax and benefit from a 0% IOF rate on the FX transaction.

Interest on equity (a form of equity distribution that, subject to certain limitations, the issuer may deduct for income tax purposes) paid to the Fund with respect to Brazilian equities, as well as any income earned by the Fund in connection with the lending of equities or securities (except for reimbursements, made by the borrower, of income distributed during the loan, which are exempt from Brazilian Withholding Income Tax for the lender), will be subject to Brazilian Withholding Income Tax at a rate of 15%.

Income from other types of investments made by the Fund in the Brazilian financial and capital markets in accordance with CMN Resolution No. 4.373/14 will generally be subject to Brazilian Withholding Income Tax at rates of 15% or 10%, except for certain specific investments that benefit from a 0% rate.

Brazilian Withholding Income Tax incurred and paid in Brazil by the Fund could be creditable against U.S. federal income tax liability.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 250,000 shares or multiples thereof. Each “creator” or authorized participant (an “Authorized Participant”) has entered into an agreement with the Fund's distributor, BlackRock Investments, LLC (the “Distributor”), an affiliate of BFA.

iSHARES^® MICRO-CAP ETF

Ticker: IWC

Stock Exchange: NYSE Arca

Investment Objective

The iShares Micro-Cap ETF (the “Fund”) seeks to track the investment results of an index composed of micro-capitalization U.S. equities.

Fees and Expenses

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

S-1

Principal Investment Strategies

The Fund seeks to track the investment results of the Russell Microcap Index (the “Underlying Index”), which measures the performance of the microcap sector of the U.S. equity market, as defined by FTSE Russell (the “Index Provider” or “Russell”). The Underlying Index is a float-adjusted capitalization-weighted index and includes equity securities issued by issuers with total market capitalizations ranging from approximately $4 million to $4.6 billion, although this range may change from time to time. The Underlying Index consists of approximately the 1,000 smallest issuers in the Russell 3000^® Index plus the next 1,000 smallest issuers in the equity universe as determined by Russell. Total market capitalization reflects all equity shares outstanding, while total market value reflects float-adjusted capitalizations based on equity shares available for general investment. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the financials and healthcare

industries or sectors. The components of the Underlying Index are likely to change over time.

S-2

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

The Underlying Index is sponsored by Russell which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

Summary of Principal Risks

net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

S-3

Healthcare Sector Risk. The profitability of companies in the healthcare sector may be affected by

government regulations and government healthcare programs, increases or decreases in the cost of medical products and services, an increased emphasis on outpatient services, and product liability claims, among other factors. Many healthcare companies are heavily dependent on patent protection, and the expiration of a company’s patent may adversely affect that company’s profitability. Healthcare companies are subject to competitive forces that may result in price discounting, and may be thinly capitalized and susceptible to product obsolescence.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over

S-4

longer periods during more prolonged market downturns.

Micro-Capitalization Companies Risk. Stock prices of microcap companies are significantly more volatile, and more vulnerable to adverse business and economic developments, than those of larger companies. Microcap stocks may also be thinly traded, making it difficult for the Fund to buy and sell them.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Risk of Investing in the United States. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets

decline, may have an adverse effect on the securities to which the Fund has exposure.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and

may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

issuer may also be subject to risks associated with the countries, states and regions in which the issuer resides, invests, sells products, or otherwise conducts operations.

Market Trading Risk

those of funds that invest solely in stocks issued by larger capitalization companies. Stock prices of micro-capitalization companies are also more vulnerable than those of larger companies to adverse business and economic developments and the stocks of micro-capitalization companies may be thinly traded, making it difficult for the Fund to buy and sell them. In addition, micro-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of key personnel, making them highly vulnerable to loss of personnel. These companies also generally have less diverse product lines than larger capitalization companies and are more susceptible to adverse developments related to their products.

The U.S. has developed increasingly strained relations with a number of foreign countries, including traditional allies, such as major European countries, the United Kingdom, Canada and Mexico, and historical adversaries, such as North Korea, Iran, China and Russia. If these relations were to worsen, it could adversely affect U.S. issuers as well as non-U.S. issuers that rely on the U.S. for trade. The U.S. has also experienced increased internal unrest and discord. If this trend were to continue, it may have an adverse impact on the U.S. economy and the issuers in which the Fund invests.

take into account the tax impact to shareholders of substitute payments for dividends when managing the Fund's securities lending program.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and

international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

Producer Durables Industry Group Risk. The producer durables industry group includes companies involved in the design, manufacture or distribution of industrial durables such as electrical equipment and components, industrial products, and housing and telecommunications equipment. These companies may be affected by changes in domestic and international economies and politics, consolidation, and excess capacity. Companies in the producer durables industry group face intense competition, which may have an adverse effect on their profitability. The success of companies in the producer durables industry group may be strongly affected by changes in consumer demands, spending, tastes and preferences. Companies in the producer durables industry group may be dependent on outside financing, which may be difficult to obtain. Producer durables companies may be unable to protect their intellectual property rights or may be liable for infringing the intellectual property rights of others. In addition, these companies may be significantly affected by other factors such as economic cycles, rapid technological obsolescence, government regulations, labor relations, delays in modernization, overall capital spending levels and product liability lawsuits.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Dividends and Distributions

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Principal Investment Strategies

The Fund seeks to track the investment results of the FTSE NAREIT All Mortgage Capped Index (the “Underlying Index”), which measures the performance of the residential and commercial mortgage real estate, mortgage finance and savings associations sectors of the U.S. equity market, as defined by FTSE International Limited (the “Index Provider” or “FTSE”). The Underlying Index generally measures the performance of the residential and commercial mortgage real estate sector and generally invests all of its assets in REITs. If the number of constituents in the Underlying Index falls below 20, FTSE will consider companies from the mortgage finance and savings associations sectors for inclusion in the Underlying Index, and each company in the mortgage finance and savings associations sectors will be capped at 3% of the Underlying Index, and these sectors in the aggregate will not exceed 30% of the Underlying Index. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, approximately

100% of the market capitalization of the Underlying Index is represented by REITs. As of March 31, 2018, the Underlying Index includes 36 component securities. The components of the Underlying Index are likely to change over time.

The Fund generally will invest at least 90% of its assets in the component

S-2

securities of the Underlying Index and may invest up to 10% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, as well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

The Underlying Index is sponsored by FTSE which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. The Fund

Cyber Security Risk. Failures or breaches of the electronic systems of

S-3

the Fund, the Fund's adviser, distributor, and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions and negatively impact the Fund’s business operations, potentially resulting in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cyber security plans and systems of the Fund’s service providers, the Index Provider, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Market Trading Risk. The Fund faces numerous market trading risks,

S-4

including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Mortgage Finance Companies Risk. Mortgage finance companies are subject to the credit risk of their borrowers, the risk that the value of a mortgaged property may be less than the amount owed on the property, and interest rate risk, among other risks.

Mortgage REITs Risk. Mortgage REITs are exposed to risks specific to the real estate market, including, among others, credit risk, interest rate risk and leverage risk.

through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

S-5

Savings Associations Risk. Savings associations are affected by extensive regulations, interest rates, loan losses, decreased availability of money or asset valuation and market conditions. The historically low interest rate environment has created certain risks to savings associations as they continue to re-evaluate their business models and risk appetites to generate returns.

Tracking Error Risk. The Fund may be subject to tracking error, which is the

divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences, differences in transaction costs, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or interest, tax gains or losses, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

More Information About the Fund

Effective December 29, 2017, the name of the Fund changed from iShares Mortgage Real Estate Capped ETF to iShares Mortgage Real Estate ETF.

“Tracking error” is the divergence of the performance (return) of the Fund's portfolio from that of the Underlying Index. BFA expects that, over time, the Fund’s tracking

error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

the securities of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

Market Trading Risk

Mortgage Finance Companies Risk. Mortgage finance companies provide mortgages, mortgage insurance, and related services to commercial and individual borrowers. Mortgage finance companies are subject to many of the same risks as mortgage REITs, including the credit risk of their borrowers, the risk that the value of a mortgaged property may be less than the amount owed on the property, and interest rate risk.

Mortgage REITs Risk. Mortgage REITs lend money to developers and owners of properties and invest primarily in mortgages and similar real estate interests. Mortgage REITs receive interest payments from the owners of the mortgaged properties. Accordingly, mortgage REITs are subject to the credit risk of the borrowers to whom they extend funds, which is the risk that the borrower will not be able to make timely interest and principal payments on the loan to the mortgage REIT. Mortgage REITs also are subject to the risk that the value of mortgaged properties may be less than the amounts owed on the properties. If a mortgage REIT is required to foreclose on a borrower, the amount recovered in connection with the foreclosure may be less than the amount owed to the mortgage REIT.

Mortgage REITs are subject to significant interest rate risk. During periods when interest rates are declining, mortgages are often refinanced or prepaid. Refinancing or prepayment of mortgages may reduce the yield of mortgage REITs. When interest rates decline, the value of a mortgage REIT’s investment in fixed rate obligations can be expected to rise. Conversely, when interest rates rise, the value of a mortgage REIT’s investment in fixed rate obligations can be expected to decline. In addition, rising interest rates generally increase the costs of obtaining financing, which could cause the value of a mortgage REIT’s investments to decline. A mortgage REIT’s investment in adjustable rate obligations may react differently to interest rate changes than an investment in fixed rate obligations. As interest rates on adjustable rate mortgage loans are reset periodically, yields on a mortgage REIT’s investment in such loans will gradually align themselves to reflect changes in market interest rates, causing the

value of such investments to fluctuate less dramatically in response to interest rate fluctuations than would investments in fixed rate obligations.

Mortgage REITs typically use leverage (and in many cases, may be highly leveraged), which increases investment risk and could adversely affect a mortgage REIT’s operations and market value in periods of rising interest rates, increased interest rate volatility, downturns in the economy, reductions in the availability of financing or deterioration in the conditions of the mortgage REIT’s mortgage-related assets.

Real Estate Investment Risk. The Fund invests in Real Estate Companies, such as REITs or real estate holding companies, which expose investors to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which Real Estate Companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments and is characterized by intense competition and periodic overbuilding. Many Real Estate Companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially increase the Fund’s losses. Rising interest rates could result in higher costs of capital for Real Estate Companies, which could negatively affect a Real Estate Company's ability to meet its payment obligations or its financing activity, and could decrease the market prices for REITs and for properties held by such REITs. The U.S. residential and commercial real estate markets may, in the future, experience and have, in the past, experienced a decline in value, with certain regions experiencing significant losses in property values. Exposure to such real estate may adversely affect Fund performance. In addition, to the extent a Real Estate Company has its own expenses, the Fund (and indirectly, its shareholders) will bear its proportionate share of such expenses.

Concentration Risk. Real Estate Companies may own a limited number of properties and concentrate their investments in a particular geographic region, industry or

property type. Economic downturns affecting a particular region, industry or property type may lead to a high volume of defaults within a short period.

and self-liquidation. In addition, transactions between Real Estate Companies and their affiliates may be subject to conflicts of interest, which may adversely affect a Real Estate Company’s shareholders. A Real Estate Company may also have joint ventures in certain of its properties and, consequently, its ability to control decisions relating to such properties may be limited.

U.S. Tax Risk. Certain U.S. Real Estate Companies are subject to special U.S. federal tax requirements. A REIT that fails to comply with such tax requirements may be subject to U.S. federal income taxation, which may affect the value of the REIT and the characterization of the REIT's distributions. The U.S. federal tax requirement that a REIT distributes substantially all of its net income to its shareholders may result in the REIT having insufficient capital for future expenditures. A REIT that successfully maintains its qualification may still become subject to U.S. federal, state and local taxes, including excise, penalty, franchise, payroll, mortgage recording, and transfer taxes, both directly and indirectly through its subsidiaries.

Savings Associations Risk. Federally- and state-chartered savings associations, such as savings and loans and other “thrift” institutions, provide banking services, including mortgage lending, and operate under the supervisory authority of the Office of the Comptroller of the Currency. Such “thrift” institutions formerly operated under the supervisory authority of the Office of Thrift Supervision. These associations are subject to extensive regulation affecting the scope of their activities, the prices they can charge, and the amount of capital they must maintain. This regulation can have the effect of limiting the profitability of these associations, and their profitability may change frequently. Savings associations may be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations and adverse conditions in other related markets. The historically low interest rate environment has created certain risks to savings associations as they continue to re-evaluate their business models and risk appetites to generate returns.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

The Fund's activities may be limited because of regulatory restrictions applicable to one or more Affiliates and/or their internal policies designed to comply with such restrictions.

on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Dividends and Distributions

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains, if any, in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, with a 25% capital gain tax rate to the extent attributable to 25% rate gain distributions received by the Fund from REITs, regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates. Long-term capital gains and qualified dividend income are generally eligible for taxation at a maximum rate of 15% or 20% for non-corporate shareholders, depending on whether their income exceeds certain threshold amounts. In addition, a 3.8% U.S. federal Medicare contribution tax is imposed on “net investment income,” including, but not limited to, interest, dividends, and net gain, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly) and of estates and trusts.

gains or upon the sale or other disposition of shares of the Fund.

Distributions to certain foreign shareholders by a Fund at least 50% of the assets of which are “U.S. real property interests” (as defined in the U.S. Internal Revenue Code and U.S. Treasury regulations) at any time during the five-year period ending on the date of the distributions, to the extent the distributions are attributable to gains from sales or exchanges of U.S. real property interests (including shares in certain “U.S. real property holding corporations” such as certain REITs, although exceptions may apply if any class of stock of such a corporation is regularly traded on an established securities market and the Fund has held no more than 5% of such class of stock at any time during the five-year period ending on the date of the distributions), generally must be treated by such foreign shareholders as income effectively connected to a trade or business within the U.S., which is generally subject to tax at the graduated rates applicable to U.S. shareholders, except for distributions to foreign shareholders that held no more than 5% of any class of stock of the Fund at any time during the previous one-year period ending on the date of the distributions. Such distributions may be subject to U.S. withholding tax and may require a foreign shareholder to file a U.S. federal income tax return. In addition, sales or redemptions of shares held by certain foreign shareholders in such a Fund generally will be subject to U.S. withholding tax and generally will require the foreign shareholder to file a U.S. federal income tax return, although exceptions may apply if more than 50% of the value of the Fund’s shares are held by U.S. shareholders or the foreign shareholder selling or redeeming the shares has held no more than 5% of any class of stock of the Fund at any time during the five-year period ending on the date of the sale or redemption.

Provided that more than 50% of the value of a Fund’s stock is held by U.S. shareholders, redemptions and other distributions made in the form of U.S. real property interests (including shares in certain “U.S. real property holding corporations”, although exceptions may apply if any class of stock of such a corporation is regularly traded on an established securities market and the Fund has held no more than 5% of such class of stock at any time during the five-year period ending on the date of the distribution) generally will cause the Fund to recognize a portion of any unrecognized gain in the U.S. real property interests equal to the product of (i) the excess of fair market value of such U.S. real property interests over the Fund’s adjusted bases in such interests and (ii) the greatest foreign ownership percentage of the Fund during the five-year period ending on the date of distribution. In addition, the same rules apply with respect to distributions to a non-U.S. shareholder from the Fund and redemptions of a non-U.S. shareholder’s interest in the Fund attributable to a REIT’s distribution to the Fund of gain from the sale or exchange of U.S. real property or an interest in a U.S. real property holding corporation. The rule with respect to distributions and redemptions attributable to a REIT’s distribution to the Fund will not expire.

account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to (i) enter into agreements with the IRS that state that they will provide the IRS information, including the names, addresses and taxpayer identification numbers of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information concerning their account holders, or (ii) in the event that an applicable intergovernmental agreement and implementing legislation are adopted, provide local revenue authorities with similar account holder information. Other foreign entities may need to report the name, address, and taxpayer identification number of each substantial U.S. owner or provide certifications of no substantial U.S. ownership unless certain exceptions apply.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and

Principal Investment Strategies

The Fund seeks to track the investment results of the NASDAQ Biotechnology Index (the “Underlying Index”), which contains securities of companies listed on NASDAQ that are classified according to the Industry Classification Benchmark as either biotechnology or pharmaceuticals and that also meet other eligibility criteria determined by Nasdaq, Inc. (the “Index Provider”), including minimum market capitalization and liquidity requirements. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the biotechnology industry or sector. The components of the Underlying Index are likely to change over time.

results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

The Underlying Index is sponsored by Nasdaq, Inc. which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

Summary of Principal Risks

Asset Class Risk. Securities and other assets in the Underlying Index or in the Fund's portfolio may underperform in comparison to the general financial

markets, a particular financial market or other asset classes.

market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions and negatively impact the Fund’s business operations, potentially resulting in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cyber security plans and systems of the Fund’s service providers, the Index Provider, market makers, Authorized Participants or issuers of securities in which the Fund invests.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Healthcare Sector Risk. The profitability of companies in the healthcare sector is affected by the following factors, among others: extensive government regulations, restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure, an increased emphasis on outpatient services, limited number of products, industry innovation, changes in technologies and other market developments. A number of issuers in the healthcare sector have recently merged or otherwise experienced consolidation. The effects of this trend toward consolidation are unknown and may be far-reaching. Many healthcare companies are heavily dependent on patent protection. The expiration of a company’s patents may adversely affect that company’s profitability. Many healthcare companies are subject to extensive litigation based on product liability and similar claims. Healthcare companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the healthcare sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly, and such efforts ultimately may be unsuccessful. Companies in the healthcare sector may be thinly capitalized and may be susceptible to product obsolescence. Companies in the life sciences tools and services industry work to develop technologies and instruments to facilitate scientific and medical research; therefore, this industry, in particular, may be negatively affected by a company’s failure to develop new or improved products that integrate technological advances.

liability in relation to the quality, accuracy or completeness of the Underlying Index or its related data, and they do not guarantee that the Underlying Index will be in line with the Index Provider’s methodology. BFA’s mandate as described in this Prospectus is to manage the Fund consistently with the Underlying Index provided by the Index Provider to BFA. BFA does not provide any warranty or guarantee against the Index Provider’s or any agent’s errors. Errors in respect of the quality, accuracy and completeness of the data used to compile the Underlying Index may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, particularly where the indices are less commonly used as benchmarks by funds or managers. Therefore, gains, losses or costs associated with errors of the Index Provider or its agents will generally be borne by the Fund and its shareholders. For example, during a period where the Underlying Index contains incorrect constituents, the Fund would have market exposure to such constituents and would be underexposed to the Underlying Index’s other constituents. Such errors may negatively or positively impact the Fund and its shareholders.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to

the risk that BFA’s investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Trading Risk

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below the Fund’s most recent NAV. The NAV of

failed or inadequate processes and technology or systems failures. The Fund and BFA seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

The U.S. has developed increasingly strained relations with a number of foreign countries, including traditional allies, such as major European countries, the United Kingdom (the “U.K.”), Canada and Mexico, and historical adversaries, such as North Korea, Iran, China and Russia. If these relations were to worsen, it could adversely affect U.S. issuers as well as non-U.S. issuers that rely on the U.S. for trade. The U.S. has also experienced increased internal unrest and discord. If this trend were to continue, it may have an adverse impact on the U.S. economy and many of the issuers in which the Fund invests.

Stock prices of small-capitalization companies are generally more vulnerable than those of mid- or large-capitalization companies to adverse business and economic developments. Securities of small-capitalization companies may be thinly traded, making it difficult for the Fund to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making these companies more vulnerable to experiencing adverse effects due to the loss of personnel. Small-capitalization companies also normally have less diverse product lines than those of mid- or large-capitalization companies and are more susceptible to adverse developments concerning their products.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

countries), the default or threat of default by an EU member state on its sovereign debt and/or an economic recession in an EU member state may have a significant adverse effect on the economies of EU member states and their trading partners. The European financial markets have historically experienced volatility and adverse trends due to concerns about economic downturns or rising government debt levels in several European countries, including, but not limited to, Austria, Belgium, Cyprus, France, Greece, Ireland, Italy, Portugal, Spain and Ukraine. These events have adversely affected the exchange rate of the euro and may continue to significantly affect European countries.

Responses to financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest, may limit future growth and economic recovery or may have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. In a referendum held on June 23, 2016, the U.K. resolved to leave the EU. The referendum may introduce significant uncertainties and instability in the financial markets as the U.K. negotiates its exit from the EU. Although the precise timeframe for the U.K.’s withdrawal is uncertain, on March 29, 2017, the U.K. initiated the withdrawal process by sending a formal notice of the country’s intention to withdraw from the EU. An agreement has been reached between the U.K. and the EU to continue negotiations on the U.K.’s exit from the EU. The outcome of negotiations remain uncertain.

Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These

deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

■	Lower levels of liquidity and market efficiency;
■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;
■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements; and

■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the U.S.

economies of individual developed countries can be impacted by slowdowns in other sectors. In the past, certain developed countries have been targets of terrorism, and some geographic areas in which the Fund invests have experienced strained international relations due to territorial disputes, historical animosities, defense concerns and other security concerns. These situations may cause uncertainty in the financial markets in these countries or geographic areas and may adversely affect the performance of the issuers to which the Fund has exposure. Heavy regulation of certain markets, including labor and product markets, may have an adverse effect on certain issuers. Such regulations may negatively affect economic growth or cause prolonged periods of recession. Many developed countries are heavily indebted and face rising healthcare and retirement expenses. In addition, price fluctuations of certain commodities and regulations impacting the import of commodities may negatively affect developed country economies.

Shareholder Information

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as

the supply of and demand for ETF shares and shares of underlying securities held by the Fund, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout each trading day by the national securities exchange on which the Fund's shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities or other assets and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities or other assets held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund's NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and price quotations obtained from broker-dealers and other market intermediaries that may trade in the portfolio securities or other assets held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the U.S. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

liquidity or other reasons, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, when there is a significant event subsequent to the most recent market quotation, or if the trading market on which a security is listed is suspended or closed and no appropriate alternative trading market is available. A “significant event” is deemed to occur if BFA determines, in its reasonable business judgment prior to or at the time of pricing the Fund’s assets or liabilities, that the event is likely to cause a material change to the closing market price of one or more assets or liabilities held by the Fund. Non-U.S. securities whose values are affected by volatility that occurs in the local markets or in related or highly correlated assets (e.g., American Depositary Receipts, Global Depositary Receipts or substantially identical ETFs) on a trading day after the close of non-U.S. securities markets may be fair valued.

Dividends and Distributions

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a

designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance for the past five years. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. Per share amounts were adjusted to reflect a three-for-one forward stock split effective after the close of trading on November 30, 2017. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund's financial statements, in the Fund's Annual Report (available upon request).

Investment Objective

The iShares North American Natural Resources ETF (the “Fund”) seeks to track the investment results of an index composed of North American equities in the natural resources sector.

Fees and Expenses

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

S-1

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P North American Natural Resources Index (the “Underlying Index”), which measures the performance of U.S.-traded stocks of natural resource-related companies in the U.S. and Canada, as determined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). The Underlying Index includes companies in the following categories: producers of oil, gas and consumable fuels; providers of energy equipment and services; metals and mining companies; manufacturers of paper and forest products; and producers of construction materials, containers and packaging. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the energy and materials industries or sectors. The components of the Underlying Index are likely to change over time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s

S-2

Index, but which BFA believes will help the Fund track the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

Asset Class Risk. Securities and other assets in the Underlying Index or in the Fund's portfolio may underperform in

comparison to the general financial markets, a particular financial market or other asset classes.

S-3

the Fund cannot control the cyber security plans and systems of the Fund’s service providers, the Index Provider, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Changes in the financial condition or credit rating of an issuer of

those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

S-4

damage claims, changes in exchange rates or depletion of natural resources.

North American Economic Risk. Economic events in any North American country can have a significant economic effect on the entire North American region and on some or all of the North American countries in which the Fund invests. Political developments in the U.S., including possible termination of trade treaties with Canada and imposition of tariffs by the U.S. and Canada on the other’s products, could negatively impact the value of securities held by the Fund.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Risk of Investing in the United States. Certain changes in the U.S. economy, such as when the U.S. economy

weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

More Information About the Fund

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Market Trading Risk

competition. Companies in the natural resources industry may be adversely affected by depletion of natural resources, technological developments, and labor relations.

Risk of Investing in the United States. The U.S. is a significant, and in some cases the most significant, trading partner of, or foreign investor in, certain markets, and the economies of these countries may be particularly affected by adverse changes in the U.S. economy. A decrease in U.S. imports, new trade regulations, changes in the U.S. dollar exchange rate or an economic slowdown in the U.S. may have a material adverse effect on the economies of these countries and, as a result, securities to which the Fund has exposure.

China and Russia. If these relations were to worsen, it could adversely affect U.S. issuers as well as non-U.S. issuers that rely on the U.S. for trade. The U.S. has also experienced increased internal unrest and discord. If this trend were to continue, it may have an adverse impact on the U.S. economy and many of the issuers in which the Fund invests.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Dividends and Distributions

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

shareholder's cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, price movement and other costs and expenses related to cash transactions (which may, in certain instances, be based on a good faith estimate of transaction costs). Investors who use the services of a broker or other financial intermediary to acquire or dispose of Fund shares may pay fees for such services.

Approximate Value of a Creation Unit		Creation Unit Size		Standard Creation/ Redemption Transaction Fee		Maximum Additional Charge for Creations*		Maximum Additional Charge for Redemptions*
$1,782,500		50,000		$500		3.0%		2.0%

*	As a percentage of the net asset value per Creation Unit, inclusive, in the case of redemptions, of the standard redemption transaction fee.

S-1

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P North American Technology Index (the “Underlying Index”), which measures the performance of U.S.-traded stocks of technology-related companies in the U.S. and Canada, as determined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). The Underlying Index includes companies in the following categories: producers of sophisticated computer-related devices; providers of communications equipment and internet services; producers of computer and internet software; consultants for information technology; providers of computer services; and semiconductors and semiconductor equipment manufacturers. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the information technology industry or sector. The components of the Underlying Index are likely to change over time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many

investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

S-2

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of

Equity Securities Risk. Equity securities are subject to changes in

S-3

value, and their values may be more volatile than those of other asset classes. The Underlying Index is comprised of common stocks, which generally subject their holders to more risks than holders of preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Large-Capitalization Companies Risk. Large-capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large-capitalization

companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large-capitalization companies has trailed the overall performance of the broader securities markets.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

S-4

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Technology Sector Risk. Technology companies, including information

technology companies, may have limited product lines, markets, financial resources or personnel. Technology companies typically face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by the loss or impairment of those rights.

substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Market Trading Risk

Risk of Investing in the United States. The U.S. is a significant, and in some cases the most significant, trading partner of, or foreign investor in, certain markets, and the

economies of these countries may be particularly affected by adverse changes in the U.S. economy. A decrease in U.S. imports, new trade regulations, changes in the U.S. dollar exchange rate or an economic slowdown in the U.S. may have a material adverse effect on the economies of these countries and, as a result, securities to which the Fund has exposure.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Portfolio Holdings Information

Management

The Fund's activities may be limited because of regulatory restrictions applicable to one or more Affiliates and/or their internal policies designed to comply with such restrictions.

Shareholder Information

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity or other reasons, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, when there is a significant event subsequent to the most recent market quotation, or if the trading market on which a security is listed is suspended or closed and no appropriate alternative trading market is available. A “significant event” is deemed to occur if BFA determines, in its reasonable business judgment prior to or at the time of pricing the Fund’s assets or liabilities, that the event is likely to cause a material change to the closing market price of one or more assets or liabilities held by the Fund. Non-U.S. securities whose values are affected by volatility that occurs in the local markets or in related or highly correlated assets (e.g., American Depositary Receipts, Global Depositary Receipts or substantially identical ETFs) on a trading day after the close of non-U.S. securities markets may be fair valued.

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P North American Technology Software Index (the “Underlying Index”), which measures the performance of U.S.-traded stocks of software-related companies in the U.S. and Canada, as determined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). The Underlying Index includes companies that are producers of client/server applications; enterprise software; application software; and home entertainment software. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the information technology industry or sector. The components of the Underlying Index are likely to change over time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and

does not seek temporary defensive positions when markets decline or appear overvalued.

S-2

results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

S-3

Provider, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

S-4

trade treaties with Canada and imposition of tariffs by the U.S. and Canada on the other’s products, could negatively impact the value of securities held by the Fund.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

These events could also trigger adverse tax consequences for the Fund.

holders to more risks than holders of preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Information Technology Sector Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect

the profitability of these companies. Companies in the application software industry, in particular, may also be negatively affected by the decline or fluctuation of subscription renewal rates for their products and services, which may have an adverse effect on profit margins. Companies in the systems software industry may be adversely affected by, among other things, actual or perceived security vulnerabilities in their products and services, which may result in individual or class action lawsuits, state or federal enforcement actions and other remediation costs.

Market Trading Risk

through funds or structured investment vehicles similar to depositary receipts. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund's shares may be less actively traded in certain markets than in others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

Shareholder Information

redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Dividends and Distributions

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

To the extent the Fund engages in in-kind transactions, the Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying

good faith estimate of transaction costs). Investors who use the services of a broker or other financial intermediary to acquire or dispose of Fund shares may pay fees for such services.

iSHARES^® PHLX SEMICONDUCTOR ETF

Ticker: SOXX

Stock Exchange: NASDAQ

Investment Objective

The iShares PHLX Semiconductor ETF (the “Fund”) seeks to track the investment results of an index composed of U.S. equities in the semiconductor sector.

Fees and Expenses

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

S-1

Principal Investment Strategies

The Fund seeks to track the investment results of the PHLX Semiconductor Sector Index (the “Underlying Index”), which measures the performance of U.S.-traded securities of companies engaged in the semiconductor business, as determined by Nasdaq, Inc. (the “Index Provider”). The Underlying Index includes companies engaged in the design, distribution, manufacture and sale of semiconductors. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the information technology and semiconductor industries or sectors. The components of the Underlying Index are likely to change over time.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

affected by the loss or impairment of those rights.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

S-4

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

These events could also trigger adverse tax consequences for the Fund.

substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Market Trading Risk

or its underlying investments, which may contribute to the Fund’s shares trading at a premium or discount to NAV.

The U.S. has developed increasingly strained relations with a number of foreign countries, including traditional allies, such as certain major European countries, the United Kingdom, Canada and Mexico, and historical adversaries, such as North Korea,

Iran, China and Russia. If these relations were to worsen, it could adversely affect U.S. issuers as well as non-U.S. issuers that rely on the U.S. for trade. The U.S. has also experienced increased internal unrest and discord. If this trend were to continue, it may have an adverse impact on the U.S. economy and many of the issuers in which the Fund invests.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks of investing in the markets where such issuers are located,

■	Lower levels of liquidity and market efficiency;
■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;
■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements; and

■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the U.S.

impaired. The capacity of the Fund to make investments in certain securities may be affected by the relevant threshold limits, and such limitations may have adverse effects on the liquidity and performance of the Fund’s portfolio holdings compared to the performance of the Underlying Index. This may increase the risk of the Fund being underinvested to the Underlying Index and increase the risk of tracking error.

Management

BFA was paid a management fee from the Fund, as a percentage of the Fund's average daily net assets, at the annual rate of 0.47%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Alan Mason has been employed by BFA as a portfolio manager since 1991. Mr. Mason has been a Portfolio Manager of the Fund since 2016.

name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Generally, trading in non-U.S. securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at

various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

Dividends and Distributions

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Approximate Value of a Creation Unit		Creation Unit Size		Standard Creation/ Redemption Transaction Fee		Maximum Additional Charge for Creations*		Maximum Additional Charge for Redemptions*
$8,433,000		50,000		$250		3.0%		2.0%

*	As a percentage of the net asset value per Creation Unit, inclusive, in the case of redemptions, of the standard redemption transaction fee.

Investment Objective

The iShares Residential Real Estate ETF (the “Fund”) seeks to track the investment results of an index composed of U.S. residential, healthcare and self-storage real estate equities.

Fees and Expenses

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

S-1

Principal Investment Strategies

The Fund seeks to track the investment results of the FTSE NAREIT All Residential Capped Index (the “Underlying Index”), which measures the performance of the residential apartments, manufactured homes, healthcare and self-storage real estate sectors of the U.S. equity market, as defined by FTSE International Limited (the “Index Provider” or “FTSE”). The Underlying Index may include large-, mid- or small-capitalization companies. Only companies with a full market capitalization greater than US $100 million by full market capitalization (on the date at which the data for the review are taken) will be included in the Underlying Index. As of March 31, 2018, a significant portion of the Underlying Index is represented by real estate investment trusts (“REITs”). The components of the Underlying Index are likely to change over time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and

does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will invest at least 90% of its assets in the component securities of the Underlying Index and may invest up to 10% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, as well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. The Fund seeks to track the investment results of the

S-2

Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

The Underlying Index is sponsored by FTSE, which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

Summary of Principal Risks

Asset Class Risk. Securities and other assets in the Underlying Index or in the Fund's portfolio may underperform in comparison to the general financial

markets, a particular financial market or other asset classes.

a period of time or at all, which may have an adverse impact on the Fund and its shareholders.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

conditions and developments, and characterized by intense competition and periodic overbuilding. Many Real Estate Companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially magnify the Fund’s losses. Rising interest rates could result in higher costs of capital for Real Estate Companies, which could negatively affect a Real Estate Company's ability to meet its payment obligations or its financing activity, and could decrease the market prices for REITs and for properties held by such REITs.

Residential and Residential-Related REIT Sub-Industry Risk. Equity REITs have exposure to residential real estate and certain types of commercial real estate, including properties operated by healthcare providers and self-storage companies. Investments in these REITs may be affected by the conditions of the rental market, property and rental values, and interest rates, among other things.

S-5

investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or interest, tax gains or losses, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

A Further Discussion of Principal Risks

market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

Market Trading Risk

decrease the market prices for REITs and for properties held by such REITs. The U.S. residential and commercial real estate markets may, in the future, experience and have, in the past, experienced a decline in value, with certain regions experiencing significant losses in property values. Exposure to such real estate may adversely affect Fund performance. In addition, to the extent a Real Estate Company has its own expenses, the Fund (and indirectly, its shareholders) will bear its proportionate share of such expenses.

U.S. Tax Risk. Certain U.S. Real Estate Companies are subject to special U.S. federal tax requirements. A REIT that fails to comply with such tax requirements may be subject to U.S. federal income taxation, which may affect the value of the REIT and the characterization of the REIT's distributions. The U.S. federal tax requirement that a REIT distributes substantially all of its net income to its shareholders may result in the REIT having insufficient capital for future expenditures. A REIT that successfully maintains its qualification may still become subject to U.S. federal, state and local taxes, including excise, penalty, franchise, payroll, mortgage recording, and transfer taxes, both directly and indirectly through its subsidiaries.

Residential and Residential-Related REIT Sub-Industry Risk. The Fund invests in Equity REITs that have exposure to residential real estate and certain types of commercial real estate, including properties operated by healthcare providers and self-storage companies. In addition to the risks related to REITs generally, investments in these Equity REITs are subject to additional subsector-specific risks. Residential real estate may be affected by unique supply and demand factors that do not apply to other REIT sub-sectors. In addition, many investors may already have exposure to residential real estate through ownership of a home. The value of healthcare-focused REITs may be affected by changes in federal or state regulation of healthcare providers and reimbursement rates to healthcare providers under Medicare, Medicaid and other public or private health insurance plans. Investments in self-storage REITs are subject to changes in demand levels for self-storage.

Distributions by the Fund of net long-term capital gains, if any, in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, with a 25% capital gain tax rate to the extent attributable to 25% rate gain distributions received by the Fund from REITs, regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates. Long-term capital gains and qualified dividend income are generally eligible for taxation at a maximum rate of 15% or 20% for non-corporate shareholders, depending on whether their income exceeds certain threshold amounts. In addition, a 3.8% U.S. federal Medicare contribution tax is imposed on “net investment income,” including, but not limited to, interest, dividends, and net gain, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly) and of estates and trusts.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and

iSHARES^® RUSSELL 1000 ETF

Ticker: IWB

Stock Exchange: NYSE Arca

Investment Objective

The iShares Russell 1000 ETF (the “Fund”) seeks to track the investment results of an index composed of large- and mid-capitalization U.S. equities.

Fees and Expenses

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

Principal Investment Strategies

The Fund seeks to track the investment results of the Russell 1000^® Index (the “Underlying Index”), which measures the performance of the large- and mid-capitalization sectors of the U.S. equity market, as defined by FTSE Russell (the “Index Provider” or “Russell”). The Underlying Index is a subset of the Russell 3000 Index, which measures the performance of the broad U.S. equity market, as defined by Russell. As of March 31, 2018, the Underlying Index included issuers representing approximately 92% of the market capitalization of all publicly-traded U.S. equity securities. The Underlying Index is a float-adjusted capitalization-weighted index of equity securities issued by the approximately 1,000 largest issuers in the Russell 3000 Index. As of March 31, 2018, the Underlying Index represented approximately 92% of the total market capitalization of the Russell 3000 Index. Total market capitalization reflects all equity shares outstanding, while total market value reflects float-adjusted capitalizations based on equity shares

available for general investment. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the financials and technology industries or sectors. The components of the Underlying Index are likely to change over time.

The Fund generally invests at least 90% of its assets in securities of the

S-2

Underlying Index and in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, as well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

The Underlying Index is sponsored by Russell, which is part of the London Stock Exchange Group and is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

liquidity in credit markets. The extent to which the Fund may invest in a company that engages in securities-related activities or banking is limited by applicable law. The impact of changes in capital requirements and recent or future regulation of any individual financial company, or of the financials sector as a whole, cannot be predicted. In recent years, cyber-attacks and technology malfunctions and failures have become increasingly frequent in this sector and have caused significant losses to companies in this sector, which may negatively impact the Fund.

Large-Capitalization Companies Risk. Large-capitalization companies may be less able than smaller capitalization companies to adapt to changing market

S-4

conditions. Large-capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large-capitalization companies has trailed the overall performance of the broader securities markets.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

or systems failures. The Fund and BFA seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

A Further Discussion of Principal Risks

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and

may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Market Trading Risk

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests

increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

relatively small number of customers, including governmental entities and utilities. As a result, governmental budget constraints may have a material adverse effect on the stock prices of companies in this sector. Energy companies may also operate in, or engage in, transactions involving countries with less developed regulatory regimes or a history of expropriation, nationalization or other adverse policies. Energy companies also face a significant risk of liability from accidents resulting in injury or loss of life or property, pollution or other environmental problems, equipment malfunctions or mishandling of materials and a risk of loss from terrorism, political strife or natural disasters. Any such event could have serious consequences for the general population of the affected area and could have an adverse impact on the Fund’s portfolio and the performance of the Fund. Energy companies can be significantly affected by the supply of, and demand for, specific products (e.g., oil and natural gas) and services, exploration and production spending, government subsidization, world events and general economic conditions. Energy companies may have relatively high levels of debt and may be more likely than other companies to restructure their businesses if there are downturns in energy markets or in the global economy.

In addition, these companies may be significantly affected by other factors such as economic cycles, rapid technological obsolescence, government regulations, labor relations, delays in modernization, overall capital spending levels and product liability lawsuits.

BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired

fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Alan Mason has been employed by BFA as a portfolio manager since 1991. Mr. Mason has been a Portfolio Manager of the Fund since 2016.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Dividends and Distributions

Other foreign entities may need to report the name, address, and taxpayer identification number of each substantial U.S. owner or provide certifications of no substantial U.S. ownership unless certain exceptions apply.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

A Further Discussion of Principal Risks

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and

may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Dividends and Distributions

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a

iSHARES^® RUSSELL 1000 PURE U.S. REVENUE ETF

Ticker: AMCA

Stock Exchange: NASDAQ

Investment Objective

The iShares Russell 1000 Pure U.S. Revenue ETF (the “Fund”) seeks to track the investment results of an index composed of U.S. companies exhibiting higher domestic sales as a proportion of the company’s total sales relative to other large- and mid-capitalization U.S. equities.

Fees and Expenses

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

Annual Fund Operating Expenses (ongoing expenses that you pay each year as a percentage of the value of your investments)
Management Fees	Distribution and Service (12b-1) Fees	Other Expenses	Total Annual Fund Operating Expenses
0.15%	None	None	0.15%

1 Year		3 Years		5 Years		10 Years
$15		$48		$85		$192

S-1

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. From inception (August 8, 2017) to the most recent fiscal year end, the Fund's portfolio turnover rate was 4% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to track the investment results of the Russell 1000^® Pure Domestic Exposure Index (the “Underlying Index”), which is designed to reflect the performance of the common stock of companies that earn a higher percentage of their revenues through sales in the U.S. as compared to other large- and mid-capitalization companies in the U.S. equity market. The Underlying Index is a subset of market capitalization-weighted Russell 1000 Index. All companies in the Russell 1000 Index that have a domestic sales ratio of 90% or greater will be included in the Underlying Index. Domestic sales ratio is calculated as the percentage of a company’s latest reported domestic revenues compared to the company's total revenues as of the data cut-off date. The Underlying Index will be reviewed and reconstituted annually in September using data at the close of the last business day of August (the data cut-off date). As of March 31, 2018, a significant portion of the Underlying Index is represented by

securities of companies in the consumer services and financials industries or sectors. The components of the Underlying Index are likely to change over time. The companies included in the Underlying Index may change over time, including changes based on a company's domestic sales ratio for inclusion in the Underlying Index. In addition, the weighting of a particular company in the Underlying Index may change over time depending on its market capitalization relative to other companies included in the Underlying Index.

S-2

fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of an applicable underlying index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

The Underlying Index is sponsored by FTSE Russell (the “Index Provider” or “Russell”), which is part of the London Stock Exchange Group and is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

Assets Under Management (AUM) Risk. From time to time, an Authorized Participant (as defined in the Creations and Redemptions section of this prospectus (the “Prospectus”)), a third-party investor, the Fund’s adviser or an affiliate of the Fund’s adviser, or a fund may invest in the Fund and hold its investment for a specific period of time in order to facilitate commencement of the Fund’s operations or to allow the Fund to achieve size or scale. There can be no assurance that any such entity would not redeem its investment or that the size of the Fund would be maintained at such levels, which could negatively impact the Fund.

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of

S-3

Consumer Services Industry Risk. Companies in the consumer services industry may be affected by, among other things, changes in the domestic and international economies, exchange rates, competition, consumers' disposable income and consumer preferences.

S-4

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

S-5

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

resulting liquidation of the Fund could cause the Fund to incur elevated transaction costs for the Fund and negative tax consequences for its shareholders.

Performance Information

As of the date of the Prospectus, the Fund has been in operation for less than one full calendar year and therefore does not report its performance information.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

Consumer Services Industry Risk. The success of consumer product manufacturers and retailers (including food and drug retailers, general retailers, media, and travel and leisure companies) is tied closely to the performance of the domestic and international economies, interest rates, exchange rates and consumer confidence. The consumer services industry depends heavily on disposable household income and consumer spending. Companies in the consumer services industry may be subject to severe competition, which may also have an adverse impact on their profitability. Changes in consumer demographics may affect the success of consumer products.

render records of Fund assets and transactions, shareholder ownership of Fund shares, and other data integral to the functioning of the Fund inaccessible or inaccurate or incomplete. Substantial costs may be incurred by the Fund in order to resolve or prevent cyber incidents in the future. While the Fund has established business continuity plans in the event of, and risk management systems to prevent, such cyber attacks, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified and that prevention and remediation efforts will not be successful. Furthermore, the Fund cannot control the cyber security plans and systems put in place by service providers to the Fund, issuers in which the Fund invests, the Index Provider, market makers or Authorized Participants. The Fund and its shareholders could be negatively impacted as a result.

Large-Capitalization Companies Risk. Large-capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions.

Large-capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large-capitalization companies has trailed the overall performance of the broader securities markets.

Market Trading Risk

restrictions on foreign investments or repatriation of capital, military coups, social or political unrest, violence or labor unrest). Companies in the oil and gas industry may have significant capital investments in, or engage in transactions involving, emerging market countries, which may heighten these risks.

Telecommunications Sector Risk. The telecommunications sector is subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new regulatory requirements may negatively affect the business of telecommunications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. The domestic telecommunications market is characterized by increasing competition and regulation by various state and federal regulatory authorities. Companies in the telecommunications sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in developing new products and services using new technology. Technological innovations may make the products and services of certain telecommunications companies obsolete. Telecommunications providers are generally required to obtain franchises or licenses in order to provide services in a given location. Licensing and franchise rights in the telecommunications sector are limited, which may provide an advantage to certain participants. Limited availability of such rights, high barriers to market entry and regulatory oversight, among other factors, have led to consolidation of companies within the sector, which could lead to further regulation or other negative effects in the future.

man-made or natural disasters. Existing and future regulations or legislation may make it difficult for utility companies to operate profitably. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. There is no assurance that regulatory authorities will grant rate increases in the future or that such increases will be adequate to permit the payment of dividends on stocks issued by a utility company. Energy conservation and changes in climate policy may also have a significant adverse impact on the revenues and expenses of utility companies.

national securities exchange on which the Fund's shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities or other assets and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities or other assets held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund's NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and price quotations obtained from broker-dealers and other market intermediaries that may trade in the portfolio securities or other assets held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the U.S. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

A “significant event” is deemed to occur if BFA determines, in its reasonable business judgment prior to or at the time of pricing the Fund’s assets or liabilities, that the event is likely to cause a material change to the closing market price of one or more assets or liabilities held by the Fund.

Dividends and Distributions

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, in which case your distributions generally

will be taxable when withdrawn, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

In the event of a system failure or other interruption, including disruptions at market makers or Authorized Participants, orders to purchase or redeem Creation Units either

may not be executed according to the Fund's instructions or may not be executed at all, or the Fund may not be able to place or change orders.

Approximate Value of a Creation Unit		Creation Unit Size		Standard Creation/ Redemption Transaction Fee		Maximum Additional Charge for Creations*		Maximum Additional Charge for Redemptions*

S-1

Principal Investment Strategies

The Fund seeks to track the investment results of the Russell 1000^® Value Index (the “Underlying Index”), which measures the performance of large- and mid-capitalization value sectors of the U.S. equity market, as defined by FTSE Russell (the “Index Provider” or “Russell”). The Underlying Index is a subset of the Russell 1000^® Index, which measures the performance of the large- and mid-capitalization sector of the U.S. equity market, as defined by Russell. As of March 31, 2018, the Underlying Index represented approximately 50% of the total market value of the Russell 1000 Index. The Underlying Index measures the performance of equity securities of Russell 1000 Index issuers with lower price-to-book ratios relative to all securities included in the Russell 1000 Index. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the financials industry or sector. The components of the Underlying Index are likely to change over time.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

trading price, yield, total return and ability to meet its investment objective.

S-3

Index-Related Risk. There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Underlying

Index or that the Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from

S-4

trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund

may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

A Further Discussion of Principal Risks

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and

may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

Market Trading Risk

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Utilities Sector Risk. Deregulation may subject utility companies to greater competition and may adversely affect their profitability. As deregulation allows utility companies to diversify outside of their original geographic regions and their traditional lines of business, utility companies may engage in riskier ventures. In addition, deregulation may eliminate restrictions on the profits of certain utility companies, but may also subject these companies to greater risk of loss. Companies in the utilities industry may have difficulty obtaining an adequate return on invested capital, raising capital, or financing large construction projects during periods of inflation or unsettled capital markets; face restrictions on operations and increased cost and delays attributable to environmental considerations and regulation; find that existing plants, equipment or products have been rendered obsolete by technological innovations; or be subject to increased costs because of the scarcity of certain fuels or the effects of man-made or natural disasters. Existing and future regulations or legislation may make it difficult for utility companies to operate profitably. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. There is no assurance that regulatory authorities will grant rate increases in the future or that such increases will be adequate to permit the payment of dividends on stocks issued by a utility company. Energy conservation and changes in climate policy may also have a significant adverse impact on the revenues and expenses of utility companies.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of

business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Investment Objective

The iShares Russell 2000 ETF (the “Fund”) seeks to track the investment results of an index composed of small-capitalization U.S. equities.

S-1

Principal Investment Strategies

The Fund seeks to track the investment results of the Russell 2000^® Index (the “Underlying Index”), which measures the performance of the small-capitalization sector of the U.S. equity market, as defined by FTSE Russell (the “Index Provider” or “Russell”). The Underlying Index is a subset of the Russell 3000 Index, which measures the performance of the broad U.S. equity market, as defined by Russell. As of March 31, 2018, the Underlying Index included issuers representing approximately 8% of the total market capitalization of all publicly-traded U.S. equity securities. The Underlying Index is a float-adjusted capitalization-weighted index of equity securities issued by the approximately 2,000 smallest issuers in the Russell 3000 Index. As of March 31, 2018, the Underlying Index represented approximately 8% of the total market capitalization of the Russell 3000 Index. Total market capitalization reflects all equity shares outstanding, while total market value reflects float-adjusted capitalizations based on equity shares available for general investment. As of March 31, 2018, a significant portion of the Underlying Index is represented by

securities of companies in the financials and health care industries or sectors. The components of the Underlying Index are likely to change over time.

S-2

securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

Asset Class Risk. Securities and other assets in the Underlying Index or in the Fund's portfolio may underperform in

comparison to the general financial markets, a particular financial market or other asset classes.

S-3

among other factors. Many healthcare companies are heavily dependent on patent protection, and the expiration of a company’s patent may adversely affect that company’s profitability. Healthcare companies are subject to competitive forces that may result in price discounting, and may be thinly capitalized and susceptible to product obsolescence.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active

S-4

market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the loaned securities fails to return

the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

A Further Discussion of Principal Risks

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and

may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

Market Trading Risk

mid- or large-capitalization companies and are more susceptible to adverse developments concerning their products.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Micro-Capitalization Companies Risk. Stock prices of micro-capitalization companies are significantly more volatile than those of larger companies and therefore the Fund's share price may increase or decrease by a much greater percentage than those of funds that invest solely in stocks issued by larger capitalization companies. Stock prices of micro-capitalization companies are also more vulnerable than those of larger companies to adverse business and economic developments and the stocks of micro-capitalization companies may be thinly traded, making it difficult for the Fund to buy and sell them. In addition, micro-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of key personnel, making them highly vulnerable to loss of personnel. These companies also generally have less diverse product lines than larger capitalization companies and are more susceptible to adverse developments related to their products.

Portfolio Holdings Information

Management

For its investment advisory services to the Fund, BFA is paid a management fee from the Fund calculated based on the aggregate average daily net assets of the following iShares funds: iShares Latin America 40 ETF, iShares MSCI Pacific ex Japan ETF, iShares Russell 2000 ETF, iShares Russell 2000 Growth ETF, iShares Russell 2000 Value ETF, iShares Select Dividend ETF and iShares U.S. Preferred Stock ETF. The management fee for the Fund equals the ratio of the Fund's net assets over the aggregate net assets of the above iShares funds multiplied by the amount calculated as follows: 0.2000% per annum of the aggregate net assets less than or equal to $46 billion, plus 0.1900% per annum of the aggregate net assets over $46 billion, up to and including $81 billion, plus 0.1805% per annum of the aggregate net assets over $81 billion, up to and including $111 billion, plus 0.1715% per annum of the aggregate net assets over $111 billion, up to and including $141 billion, plus 0.1630% of the aggregate net assets in excess of $141 billion. Based on the assets of the iShares funds listed above as of March 31, 2018, for its investment advisory services to the Fund, BFA was paid a management fee from the Fund, as a percentage of the Fund's average daily net assets, at the annual rate of 0.19%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund

operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Alan Mason has been employed by BFA as a portfolio manager since 1991. Mr. Mason has been a Portfolio Manager of the Fund since 2016.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

The prices at which creations and redemptions occur are based on the next calculation of NAV after a creation or redemption order is received in an acceptable form under

the authorized participant agreement. If the Trust determines, based on information available to the Trust when a redemption request is submitted by an Authorized Participant, that (i) the short interest of the Fund in the marketplace is greater than or equal to 150% and (ii) the orders in the aggregate from all Authorized Participants redeeming Fund shares on such Business Day represent 25% or more of the outstanding shares of the Fund, such Authorized Participant will be required to verify to the Trust the accuracy of its deemed representations (as described in the Fund's SAI). If, after receiving notice of the verification requirement, the Authorized Participant does not verify the accuracy of its deemed representations in accordance with this requirement, its redemption request will be considered not to have been timely received in proper form.

Approximate Value of a Creation Unit		Creation Unit Size		Standard Creation/ Redemption Transaction Fee		Maximum Additional Charge for Creations*		Maximum Additional Charge for Redemptions*
$7,664,000		50,000		$3,000		3.0%		2.0%

Principal Investment Strategies

The Fund seeks to track the investment results of the Russell 2000 Growth Index (the “Underlying Index”), which measures the performance of the small-capitalization growth sector of the U.S. equity market, as defined by FTSE Russell (the “Index Provider” or “Russell”). The Underlying Index is a subset of the Russell 2000^® Index, which measures the performance of the small-capitalization sector of the U.S. equity market, as defined by Russell. As of March 31, 2018, the Underlying Index represented approximately 49% of the total market value of the Russell 2000 Index. The Underlying Index measures the performance of equity securities of Russell 2000 Index issuers with higher price-to-book ratios and higher forecasted growth relative to all issuers included in the Russell 2000 Index. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the consumer discretionary, healthcare, producer durables and technology industries or sectors. The components of the

Underlying Index are likely to change over time.

securities with different investment parameters. Under certain market conditions, growth securities have performed better during the later stages of economic recovery. Therefore, growth securities may go in and out of favor over time.

S-4

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Passive Investment Risk. The Fund is not actively managed, and BFA generally

does not attempt to take defensive positions under any market conditions, including declining markets.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and

may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

Market Trading Risk

Producer Durables Industry Group Risk. The producer durables industry group includes companies involved in the design, manufacture or distribution of industrial

durables such as electrical equipment and components, industrial products, and housing and telecommunications equipment. These companies may be affected by changes in domestic and international economies and politics, consolidation, and excess capacity. Companies in the producer durables industry group face intense competition, which may have an adverse effect on their profitability. The success of companies in the producer durables industry group may be strongly affected by changes in consumer demands, spending, tastes and preferences. Companies in the producer durables industry group may be dependent on outside financing, which may be difficult to obtain. Producer durables companies may be unable to protect their intellectual property rights or may be liable for infringing the intellectual property rights of others. In addition, these companies may be significantly affected by other factors such as economic cycles, rapid technological obsolescence, government regulations, labor relations, delays in modernization, overall capital spending levels and product liability lawsuits.

making it difficult for the Fund to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making these companies more vulnerable to experiencing adverse effects due to the loss of personnel. Small-capitalization companies also normally have less diverse product lines than those of mid- or large-capitalization companies and are more susceptible to adverse developments concerning their products.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

stock prices of companies in this sector. Energy companies may also operate in, or engage in, transactions involving countries with less developed regulatory regimes or a history of expropriation, nationalization or other adverse policies. Energy companies also face a significant risk of liability from accidents resulting in injury or loss of life or property, pollution or other environmental problems, equipment malfunctions or mishandling of materials and a risk of loss from terrorism, political strife or natural disasters. Any such event could have serious consequences for the general population of the affected area and could have an adverse impact on the Fund’s portfolio and the performance of the Fund. Energy companies can be significantly affected by the supply of, and demand for, specific products (e.g., oil and natural gas) and services, exploration and production spending, government subsidization, world events and general economic conditions. Energy companies may have relatively high levels of debt and may be more likely than other companies to restructure their businesses if there are downturns in energy markets or in the global economy.

it difficult for utility companies to operate profitably. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. There is no assurance that regulatory authorities will grant rate increases in the future or that such increases will be adequate to permit the payment of dividends on stocks issued by a utility company. Energy conservation and changes in climate policy may also have a significant adverse impact on the revenues and expenses of utility companies.

of the Fund's average daily net assets, at the annual rate of 0.24%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Alan Mason has been employed by BFA as a portfolio manager since 1991. Mr. Mason has been a Portfolio Manager of the Fund since 2016.

Shareholder Information

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Generally, trading in non-U.S. securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at

various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

Dividends and Distributions

may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

Other foreign entities may need to report the name, address, and taxpayer identification number of each substantial U.S. owner or provide certifications of no substantial U.S. ownership unless certain exceptions apply.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

iSHARES^® RUSSELL 2500 ETF

Ticker: SMMD

Stock Exchange: Cboe BZX

Investment Objective

The iShares Russell 2500 ETF (the “Fund”) seeks to track the investment results of an index composed of mid- and small-capitalization U.S. equities.

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except the management fees, interest expenses, taxes, expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, distribution fees or expenses, litigation expenses and any extraordinary expenses. The Fund may incur “Acquired Fund Fees and Expenses.” Acquired Fund Fees and Expenses reflect the Fund's pro rata share of the fees and expenses incurred by investing in other investment companies. As the Fund has not commenced operations prior to the date of the Fund’s prospectus (the “Prospectus”), Acquired Fund Fees and Expenses are based on an estimate of the Fund’s allocation to other investment companies for the current fiscal year. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees in an amount equal to the Acquired Fund Fees and Expenses, if any, attributable to the Fund's investments in other series of the Trust and iShares, Inc. through July 31, 2022, provided that the waiver be no greater than the Fund's management fee of 0.15%. The contractual waiver may be terminated prior to July 31, 2022 only upon written agreement of the Trust and BFA.

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

Portfolio Turnover. The Fund and the underlying fund in which the Fund invests, the iShares Russell 2000 ETF (the “Underlying Fund”), may pay transaction costs, such as commissions, when they buy and sell securities (or “turn over” their portfolios). A higher portfolio turnover rate for the Fund or the Underlying Fund may indicate higher transaction costs and may cause the Fund or the Underlying Fund to incur increased expenses. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example (except costs to the Underlying Fund included as part of Acquired Fund Fees and Expenses), affect the Fund’s performance. From inception (July 6, 2017) to the most recent fiscal year end, the Fund's portfolio turnover rate was 5% of the average value of its portfolio. To the extent the Underlying Fund incurs costs from high portfolio turnover, such costs may have a negative effect on the performance of the Fund.

Principal Investment Strategies

The Fund seeks to track the investment results of the Russell 2500^TMIndex (the “Underlying Index”), which measures the performance of the small- to mid-

capitalization sector of the U.S. equity market, as defined by FTSE Russell (the “Index Provider” or “Russell”). The Underlying Index is a subset of the Russell 3000 Index, which measures the performance of the broad U.S. equity market, as defined by Russell. As of March 31, 2018, the Underlying Index included issuers representing approximately 19% of the market capitalization of all publicly-traded U.S. equity securities. The Underlying Index is a float-adjusted capitalization-weighted index of equity securities issued by approximately 2,500 of the smallest issuers in the Russell 3000 Index. As of March 31, 2018, the Underlying Index represented approximately 18% of the total market capitalization of the Russell 3000 Index. Total market capitalization reflects all equity shares outstanding, while total market value reflects float-adjusted capitalizations based on equity shares available for general investment. As of March 31, 2018 a significant portion of the Underlying Index is represented by securities of companies in the financials and producer durables industries or sectors. The components of the Underlying Index are likely to change over time.

Currently, the Fund seeks to achieve its investment objective by investing a

S-2

substantial portion of its assets in the Underlying Fund. However, BFA is not required to invest any portion, or any particular percentage, of the Fund's assets in the Underlying Fund.

BFA uses a representative sampling indexing strategy to manage the Fund and the Underlying Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to that of an applicable underlying index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of an applicable underlying index. The Fund may or may not hold all of the securities in the applicable Underlying Index.

The Fund generally will invest at least 90% of its assets in the component securities, including indirect

investments through the Underlying Fund, of the Underlying Index and may invest up to 10% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates, as well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

The Underlying Index is sponsored by Russell, which is part of the London Stock Exchange Group and is independent of the Fund and BFA. Russell determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the

S-3

Fund, and the Fund's performance could trail that of other investments. The Fund is subject to certain risks, including the principal risks noted below (either directly or through its investments in the Underlying Fund), any of which may adversely affect the Fund's net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Assets Under Management (AUM) Risk. From time to time, an Authorized Participant (as defined in the Creations and Redemptions section of the Prospectus), a third-party investor, the Fund’s adviser or an affiliate of the Fund’s adviser, or a fund may invest in the Fund and hold its investment for a specific period of time in order to facilitate commencement of the Fund’s operations or to allow the Fund to achieve size or scale. There can be no assurance that any such entity would not redeem its investment or that the size of the Fund would be maintained at such levels, which could negatively impact the Fund.

Cyber Security Risk. Failures or breaches of the electronic systems of the Fund or the Underlying Fund, the Fund's or the Underlying Fund's adviser, distributor, or other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund or the Underlying Fund invests have the ability to cause disruptions and negatively impact the Fund’s business operations, potentially resulting in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cyber security plans and systems of the Fund’s service providers, the Index Provider, market makers, Authorized Participants or issuers of securities in which the Fund or the Underlying Fund invests.

S-4

Investment in the Underlying Fund Risk. The Fund may invest a substantial portion of its assets in the Underlying Fund, so the Fund’s investment performance may be directly related to the performance of the Underlying Fund. The Fund’s NAV will change with changes in the value of the Underlying Fund and other securities in which the Fund invests based on their market valuations. To the extent the Fund invests in the Underlying Fund, an investment in the Fund may entail more costs and expenses than a direct investment in the Underlying Fund.

As the Fund’s allocation to the Underlying Fund changes from time to time, or to the extent that the expense ratio of the Underlying Fund changes, the weighted average operating

S-5

expenses borne by the Fund may increase or decrease.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund and the Underlying Fund have exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund and the Underlying Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Market Trading Risk. The Fund and the Underlying Fund face numerous market trading risks, including the potential lack of an active market for their shares, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Operational Risk. The Fund and the Underlying Fund are exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and

communication errors, errors of the Fund’s or the Underlying Fund's service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund, the Underlying Fund and BFA seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

S-6

securities fails to return the securities in a timely manner or at all. The Fund or the Underlying Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Tracking Error Risk. The Fund may be subject to tracking error, which is the

divergence of the Fund’s or the underlying fund's performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s or the underlying fund's portfolio and those included in the Underlying Index, pricing differences, differences in transaction costs, the Fund’s or the underlying fund's holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or interest, tax gains or losses, changes to the Underlying Index or the costs to the Fund or the underlying fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund or the underlying fund incurs fees and expenses, while the Underlying Index does not.

Performance Information

As of the date of the Prospectus, the Fund has been in operation for less than one full calendar year and therefore does not report its performance information.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. The Fund may be exposed to these risks directly or indirectly through the Fund's investments in the Underlying Fund. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asset Class Risk. The securities and other assets in the Underlying Index or in the Fund’s or the Underlying Fund's portfolio may underperform in comparison to other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities, currencies and indexes may experience cycles of outperformance and underperformance in comparison to the general financial markets depending upon a number of factors including, among other things, inflation, interest rates, productivity, global demand for local products or resources, and regulation and governmental controls. This may cause the Fund to underperform other investment vehicles that invest in different asset classes.

basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's or the Underlying Fund's investments are concentrated in the securities of a particular issuer or issuers, country, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

Cyber Security Risk. With the increased use of technologies such as the internet to conduct business, the Fund, the Underlying Fund, Authorized Participants, service providers and the relevant listing exchange are susceptible to operational, information security and related “cyber” risks both directly and through their service providers. Similar types of cyber security risks are also present for issuers of securities in which the Fund or the Underlying Fund invests, which could result in material adverse consequences for such issuers and may cause the Fund’s or the Underlying Fund's investment in such portfolio companies to lose value. Unlike many other types of risks faced by the Fund and the Underlying Fund, these risks typically are not covered by insurance. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber incidents include, but are not limited to, gaining unauthorized access to digital systems (e.g., through “hacking” or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cyber attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make network services unavailable to intended users). Cyber security failures by or breaches of the systems of the Fund’s or the Underlying Fund's adviser, distributor and other service providers (including, but not limited to, index providers, fund accountants, custodians, transfer agents and administrators), market makers, Authorized Participants or the issuers of securities in which the Fund or the Underlying Fund invests, have the ability to cause disruptions and impact business operations, potentially resulting in: financial losses, interference with the Fund’s or the Underlying Fund's ability to calculate its NAV, disclosure of confidential trading information, impediments to trading, submission of erroneous trades or erroneous creation or redemption orders, the inability of the Fund, the Underlying Fund or their service providers to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. In addition, cyber attacks may render records of Fund assets and transactions, shareholder ownership of Fund shares, and other data integral to the functioning of the Fund or the Underlying Fund inaccessible or inaccurate or incomplete. Substantial costs may be incurred by the Fund or the Underlying Fund in order to resolve or

prevent cyber incidents in the future. While the Fund and the Underlying Fund have established business continuity plans in the event of, and risk management systems to prevent, such cyber attacks, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified and that prevention and remediation efforts will not be successful. Furthermore, the Fund cannot control the cyber security plans and systems put in place by service providers to the Fund, issuers in which the Fund invests, the Index Provider, market makers or Authorized Participants. The Fund and its shareholders could be negatively impacted as a result.

Index-Related Risk. The Fund seeks to achieve a return that corresponds generally to the price and yield performance, before fees and expenses, of the Underlying Index as

published by the Index Provider. There is no assurance that the Index Provider or any agents that may act on its behalf will compile the Underlying Index accurately, or that the Underlying Index will be determined, composed or calculated accurately. While the Index Provider provides descriptions of what the Underlying Index is designed to achieve, neither the Index Provider nor its agents provide any warranty or accept any liability in relation to the quality, accuracy or completeness of the Underlying Index or its related data, and they do not guarantee that the Underlying Index will be in line with the Index Provider’s methodology. BFA’s mandate as described in this Prospectus is to manage the Fund consistently with the Underlying Index provided by the Index Provider to BFA. BFA does not provide any warranty or guarantee against the Index Provider’s or any agent’s errors. Errors in respect of the quality, accuracy and completeness of the data used to compile the Underlying Index may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, particularly where the indices are less commonly used as benchmarks by funds or managers. Therefore, gains, losses or costs associated with errors of the Index Provider or its agents will generally be borne by the Fund and its shareholders. For example, during a period where the Underlying Index contains incorrect constituents, the Fund would have market exposure to such constituents and would be underexposed to the Underlying Index’s other constituents. Such errors may negatively or positively impact the Fund and its shareholders.

Similar risks exist for the Underlying Fund in tracking its benchmark, which may result in the Fund's performance deviating from the return of the Underlying Index.

in this sector tend to rely to a significant extent on government demand for their products and services.

Investment in the Underlying Fund Risk. The Fund may invest a substantial portion of its assets in the Underlying Fund, so the Fund’s investment performance may be directly related to the performance of the Underlying Fund. The Fund may also invest in other funds, including money market funds. The Fund’s NAV will change with changes in the value of the Underlying Fund and other securities in which the Fund invests based on their market valuations. To the extent the Fund invests in the Underlying Fund, an investment in the Fund may entail more direct and indirect costs and expenses than a direct investment in the Underlying Fund. For example, the Fund indirectly pays a portion of the expenses (including operating expenses and management fees) incurred by the Underlying Fund, although some of such fees will be offset by the fee waiver by BFA.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund or the Underlying Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures, credit deterioration of the issuer or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline. An issuer may also be subject to risks associated with the countries, states and regions in which the issuer resides, invests, sells products, or otherwise conducts operations.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to

the risk that BFA’s investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund and the Underlying Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. The value of a security or other asset may decline due to changes in general market conditions, economic trends or events that are not specifically related to the issuer of the security or other asset, or factors that affect a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class. During a general market downturn, multiple asset classes may be negatively affected. Changes in market conditions and interest rates generally do not have the same impact on all types of securities and instruments.

Market Trading Risk

Risk of Secondary Listings. The Fund's and the Underlying Fund's shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund's primary listing is maintained, and may otherwise be made available to non-U.S. investors through funds or structured investment vehicles similar to depositary receipts. There can be no assurance that the Fund’s or the Underlying Fund's shares will continue to trade on any such stock exchange or in any market or that the Fund’s or the Underlying Fund's shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund's or the Underlying Fund's shares may be less actively traded in certain markets than in others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund or Underlying Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market.

Shares of the Fund and the Underlying Fund May Trade at Prices Other Than NAV. Shares of the Fund and the Underlying Fund each trade on stock exchanges at prices at, above or below the Fund’s most recent NAV. The NAV of the Fund and the Underlying Fund are calculated at the end of each business day and fluctuate with changes in the market value of the Fund’s or the Underlying Fund's holdings. The trading price of each of the Fund's and the Underlying Fund's shares fluctuates continuously throughout trading hours based on both market supply of and demand for their shares and the underlying value of their portfolio holdings or NAV. As a result, the trading prices of the Fund’s and the Underlying Fund's shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S OR THE UNDERLYING FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV, BFA believes that large discounts or premiums to the NAV of the Fund or the Underlying Fund, as applicable, are not likely to be sustained over the long term (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs). While the creation/redemption feature is designed to make it more likely that the Fund’s or the Underlying Fund's shares normally will trade on stock exchanges at prices close to the Fund’s or the Underlying Fund's next calculated NAV, exchange prices are not expected to correlate exactly with the NAV due to timing reasons, supply and demand imbalances and other factors. In addition, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants, or other market participants, and during periods of significant market volatility, may result in trading prices for shares of the Fund or the Underlying Fund that differ significantly from their respective NAV. Authorized Participants may be less willing to create or redeem Fund or Underlying Fund shares if there is a lack of an active market for such shares or its underlying investments, which may contribute to the Fund’s or Underlying Fund's shares trading at a premium or discount to NAV.

significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments through a brokerage account.

Mid-Capitalization Companies Risk. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, the Fund’s or the Underlying Fund's respective share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell shares of mid-capitalization companies. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments.

Passive Investment Risk. The Fund and the Underlying Fund are not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index, regardless of their investment merits. BFA generally does not attempt to invest the Fund's assets in defensive positions under any market conditions, including declining markets.

liquidation of the Fund could cause the Fund to incur elevated transaction costs for the Fund and negative tax consequences for its shareholders.

Tracking Error Risk. The Fund may be subject to tracking error, which is the divergence of the Fund’s or the underlying fund's performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s or the underlying fund's portfolio and those included in the Underlying Index, pricing differences, differences in transaction costs, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or interest, tax gains or losses, changes to the Underlying Index or the costs to the Fund or the underlying fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund or the underlying fund incurs fees and expenses, while the Underlying Index does not.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies either directly or indirectly through the Fund's investments in the Underlying Fund.

sector have recently merged or otherwise experienced consolidation. The effects of this trend toward consolidation are unknown and may be far-reaching. Many healthcare companies are heavily dependent on patent protection. The expiration of a company’s patents may adversely affect that company’s profitability. Many healthcare companies are subject to extensive litigation based on product liability and similar claims. Healthcare companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the healthcare sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly, and such efforts ultimately may be unsuccessful. Companies in the healthcare sector may be thinly capitalized and may be susceptible to product obsolescence. In addition, a number of legislative proposals concerning healthcare have been considered by the U.S. Congress in recent years. It is unclear what proposals will ultimately be enacted, if any, and what effect they may have on companies in the healthcare sector.

Real Estate Investment Risk. The Fund may invest in companies that invest in real estate (“Real Estate Companies”), such as real estate investment trusts (“REITs”), real estate holding companies, or real estate management or development companies which expose investors to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which Real Estate Companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments and is characterized by intense competition and periodic overbuilding. Many Real Estate Companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially increase the Fund’s losses. Rising interest rates could result in higher costs of capital for Real Estate Companies, which could negatively affect a Real Estate Company's ability to meet its payment obligations or its financing activity, and could decrease the market prices for REITs and for properties held by such REITs. In addition, to the extent a Real Estate Company has its own expenses, the Fund (and indirectly, its shareholders) will bear its proportionate share of such expenses.

U.S. Tax Risk. Certain U.S. Real Estate Companies are subject to special U.S. federal tax requirements. A REIT that fails to comply with such tax requirements may be subject to U.S. federal income taxation, which may affect the value of the REIT and the characterization of the REIT's distributions. The U.S. federal tax requirement that a REIT distributes substantially all of its net income to its shareholders may result in the REIT having insufficient capital for future expenditures. A REIT that successfully maintains its qualification may still become subject to U.S. federal, state and local taxes, including excise, penalty, franchise, payroll, mortgage recording, and transfer taxes, both directly and indirectly through its subsidiaries.

A Further Discussion of Principal Investment Strategies

Overview

The Fund allocates and reallocates its assets among direct investments in securities and investments in the Underlying Fund, consistent with the allocation and reallocation of securities in the Underlying Index as determined by Russell. In addition to investing in the Underlying Fund and securities of the Underlying Index, the Fund may borrow and may lend its portfolio securities to brokers, dealers and financial institutions and invest the collateral in certain short-term instruments, either directly or through one or more money market funds, as described in greater detail in the Fund’s SAI.

The Underlying Fund

The Fund may invest a substantial portion of its assets in the Underlying Fund, so the Fund’s investment performance may be directly related to the performance of the Underlying Fund. To the extent the Fund invests in the Underlying Fund, an investment in the Fund may entail more direct and indirect costs and expenses than a direct investment in the Underlying Fund.

Currently, the Fund seeks to achieve its investment objective by investing a substantial portion of its assets in the Underlying Fund. However, BFA is not required to invest any portion, or any particular portion of, the Fund’s assets in the Underlying Fund.

The Underlying Fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the Russell 2000 Index. The Russell 2000 Index is a servicemark of the Index Provider and has been licensed for use for certain purposes by BFA or its affiliates. The Underlying Fund is not sponsored, endorsed, sold, or promoted by the Index Provider, and the Index Provider makes no representation regarding the advisability of investing in the Underlying Fund.

return variability and yield) and liquidity measures similar to those of the applicable underlying index. The Underlying Fund may or may not hold all of the securities that are included in its underlying index and may hold certain securities or other instruments that are not included in its underlying index.

Management

For its investment advisory services to the Fund, BFA is paid a management fee from the Fund based on a percentage of the Fund's average daily net assets, at the annual rate of 0.15%. BFA has contractually agreed to waive a portion of its management fees in an amount equal to the Acquired Fund Fees and Expenses, if any, attributable to the Fund's investments in other series of the Trust and iShares, Inc. through July 31, 2022, provided that the waiver be no greater than the Fund's management fee of 0.15%. The contractual waiver may be terminated prior to July 31, 2022 only upon written agreement of the Trust and BFA. In addition, BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit Total Annual Fund Operating Expenses (excluding Acquired Fund Fees and Expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

research provider, investment manager, commodity pool operator, commodity trading advisor, financier, underwriter, adviser, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests in securities, currencies, commodities, derivatives and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA or an Affiliate performs or seeks to perform investment banking or other services. Specifically, the Fund may invest in securities of, or engage in other transactions with, companies with which an Affiliate has developed or is trying to develop investment banking relationships or in which an Affiliate has significant debt or equity investments or other interests. The Fund also may invest in securities of, or engage in other transactions with, companies for which an Affiliate provides or may in the future provide research coverage. An Affiliate may have business relationships with, and purchase, distribute or sell services or products from or to, distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates in connection with the Fund's portfolio investment transactions.

The Fund's activities may be limited because of regulatory restrictions applicable to one or more Affiliates and/or their internal policies designed to comply with such restrictions.

Shareholder Information

price quotations obtained from broker-dealers and other market intermediaries that may trade in the portfolio securities or other assets held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the U.S. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets, which includes the values of the Underlying Fund shares in which the Fund invests, less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Dividends and Distributions

sales.” Capital loss carryforwards of the Underlying Fund, if any, would not offset net capital gains of the Fund.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. Distributions in excess of the Fund’s minimum distribution requirements, but not in excess of the Fund’s earnings and profits, will be taxable to shareholders and will not constitute nontaxable returns of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder's cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

In the event of a system failure or other interruption, including disruptions at market makers or Authorized Participants, orders to purchase or redeem Creation Units either

may not be executed according to the Fund's instructions or may not be executed at all, or the Fund may not be able to place or change orders.

Approximate Value of a Creation Unit		Creation Unit Size		Standard Creation/ Redemption Transaction Fee		Maximum Additional Charge for Creations*		Maximum Additional Charge for Redemptions*

Principal Investment Strategies

The Fund seeks to track the investment results of the Russell 3000^® Index (the “Underlying Index”), which measures the performance of the broad U.S. equity market, as defined by FTSE Russell (the “Index Provider” or “Russell”). As of March 31, 2018, the Underlying Index included issuers representing approximately 99% of the total market capitalization of all publicly-traded U.S.-domiciled equity securities. The Underlying Index is a float-adjusted capitalization-weighted index of the approximately 3,000 largest public issuers domiciled in the U.S. and its territories, as determined by Russell. Total market capitalization reflects all equity shares outstanding, while total market value reflects float-adjusted capitalizations based on equity shares available for general investment. The Underlying Index includes large-, mid- and small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the financials and technology industries or sectors. The

components of the Underlying Index are likely to change over time.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

A Further Discussion of Principal Risks

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and

may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Market Trading Risk

economic growth and the securities to which the Fund has exposure.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Close-out Risk for Qualified Financial Contracts. Recently adopted regulations of the Prudential Regulators, which are scheduled to take effect with respect to the Fund

in 2019, will require counterparties that are part of U.S. or foreign global systemically important banking organizations to include contractual restrictions on close-out and cross-default in agreements relating to qualified financial contracts. Qualified financial contracts include agreements relating to swaps, currency forwards and other derivatives as well as repurchase agreements and securities lending agreements. The restrictions prevent the Fund from closing out a qualified financial contract during a specified time period if the counterparty is subject to resolution proceedings and prohibit the Fund from exercising default rights due to a receivership or similar proceeding of an affiliate of the counterparty. Implementation of these requirements may increase credit and other risks to the Fund.

Energy companies can be significantly affected by the supply of, and demand for, specific products (e.g., oil and natural gas) and services, exploration and production spending, government subsidization, world events and general economic conditions. Energy companies may have relatively high levels of debt and may be more likely than other companies to restructure their businesses if there are downturns in energy markets or in the global economy.

Producer durables companies may be unable to protect their intellectual property rights or may be liable for infringing the intellectual property rights of others. In addition, these companies may be significantly affected by other factors such as economic cycles, rapid technological obsolescence, government regulations, labor relations, delays in modernization, overall capital spending levels and product liability lawsuits.

iSHARES^® RUSSELL MID-CAP ETF

Ticker: IWR

Stock Exchange: NYSE Arca

Investment Objective

The iShares Russell Mid-Cap ETF (the “Fund”) seeks to track the investment results of an index composed of mid-capitalization U.S. equities.

Fees and Expenses

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

S-1

Principal Investment Strategies

The Fund seeks to track the investment results of the Russell Midcap Index (the “Underlying Index”), which measures the performance of the mid-capitalization sector of the U.S. equity market, as defined by FTSE Russell (the “Index Provider” or “Russell”). The Underlying Index is a subset of the Russell 1000^® Index, which measures the performance of the large- and mid-capitalization sectors of the U.S. equity market, as defined by Russell. As of March 31, 2018, the Underlying Index represented approximately 27% of the total market capitalization of all publicly-traded U.S. equity securities. The Underlying Index is a float-adjusted capitalization-weighted index of equity securities issued by the approximately 800 smallest issuers in the Russell 1000 Index. Total market capitalization reflects all equity shares outstanding, while total market value reflects float-adjusted capitalizations based on equity shares available for general investment. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies

in the financials industry or sector. The components of the Underlying Index are likely to change over time.

S-2

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

principal risks noted below, any of which may adversely affect the Fund's net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Cyber Security Risk. Failures or breaches of the electronic systems of the Fund, the Fund's adviser,

S-3

financial company, or of the financials sector as a whole, cannot be predicted. In recent years, cyber-attacks and technology malfunctions and failures have become increasingly frequent in this sector and have caused significant losses to companies in this sector, which may negatively impact the Fund.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

S-4

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Risk of Investing in the United States. Certain changes in the U.S. economy, such as when the U.S. economy

weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and

may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Market Trading Risk

Proposed and adopted policy and legislative changes in the U.S. are changing many aspects of financial and other regulation and may have a significant effect on the U.S. markets generally, as well as on the value of certain securities. In addition, a continued rise in the U.S. public debt level or U.S. austerity measures may adversely affect U.S. economic growth and the securities to which the Fund has exposure.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Utilities Sector Risk. Deregulation may subject utility companies to greater competition and may adversely affect their profitability. As deregulation allows utility companies to diversify outside of their original geographic regions and their traditional lines of business, utility companies may engage in riskier ventures. In addition, deregulation may eliminate restrictions on the profits of certain utility companies, but may also subject these companies to greater risk of loss. Companies in the utilities industry may have difficulty obtaining an adequate return on invested capital, raising capital, or financing large construction projects during periods of inflation or unsettled capital markets; face restrictions on operations and increased cost and delays attributable to environmental considerations and regulation; find that existing plants, equipment or products have been rendered obsolete by technological innovations; or be subject to increased costs because of the scarcity of certain fuels or the effects of man-made or natural disasters. Existing and future regulations or legislation may make it difficult for utility companies to operate profitably. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. There is no assurance that regulatory authorities will grant rate increases in the future or that such increases will be adequate to permit the payment of dividends on stocks issued by a utility company. Energy conservation and changes in climate policy may also have a significant adverse impact on the revenues and expenses of utility companies.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Dividends and Distributions

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities (including any portion of such securities for which cash may be

substituted) held by the Fund and a specified amount of cash. Except when aggregated in Creation Units, shares are not redeemable by the Fund.

Principal Investment Strategies

The Fund seeks to track the investment results of the Russell Midcap Growth Index (the “Underlying Index”), which measures the performance of the mid-capitalization growth sector of the U.S. equity market, as defined by FTSE Russell (the “Index Provider” or “Russell”). The Underlying Index is a subset of the Russell Midcap^® Index, which measures the performance of the mid-capitalization sector of the U.S. equity market, as defined by Russell. As of March 31, 2018, the Underlying Index represented approximately 45% of the total market value of the Russell Midcap Index. The Underlying Index measures the performance of equity securities of Russell Midcap Index issuers with higher price-to-book ratios and higher forecasted growth relative to all securities included in the Russell Midcap Index. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the consumer discretionary, financials and technology industries or sectors. The components of the Underlying Index are likely to change over time.

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, region, market, industry, group of industries, sector or asset class.

Companies in the technology sector are heavily dependent on patent and other intellectual property rights.

Companies in the healthcare sector may be thinly capitalized and may be susceptible to product obsolescence.

It is unclear what proposals will ultimately be enacted, if any, and what effect they may have on companies in the healthcare sector.

Based on the assets of the iShares funds listed above as of March 31, 2018, for its investment advisory services to the Fund, BFA was paid a management fee from the Fund, as a percentage of the Fund's average daily net assets, at the annual rate of 0.24%.

Alan Mason has been employed by BFA as a portfolio manager since 1991. Mr. Mason has been a Portfolio Manager of the Fund since 2016.

Shareholder Information

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might

reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the prices at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

Dividends and Distributions

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice.

You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax advisor about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Principal Investment Strategies

The Fund seeks to track the investment results of the Russell Midcap Value Index (the “Underlying Index”), which measures the performance of the mid-capitalization value sector of the U.S. equity market, as defined by FTSE Russell (the “Index Provider” or “Russell”). The Underlying Index is a subset of the Russell Midcap^® Index, which measures the performance of the mid-capitalization sector of the U.S. equity market, as defined by Russell. As of March 31, 2018, the Underlying Index represented approximately 55% of the total market value of the Russell Midcap Index. The Underlying Index measures the performance of equity securities of Russell Midcap Index issuers with relatively lower price-to-book ratios and lower forecasted growth relative to all securities included in the Russell Midcap Index. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the financials industry or sector. The components of the Underlying Index are likely to change over time.

A Further Discussion of Principal Risks

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and

may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Market Trading Risk

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

important banking organizations to include contractual restrictions on close-out and cross-default in agreements relating to qualified financial contracts. Qualified financial contracts include agreements relating to swaps, currency forwards and other derivatives as well as repurchase agreements and securities lending agreements. The restrictions prevent the Fund from closing out a qualified financial contract during a specified time period if the counterparty is subject to resolution proceedings and prohibit the Fund from exercising default rights due to a receivership or similar proceeding of an affiliate of the counterparty. Implementation of these requirements may increase credit and other risks to the Fund.

and may be more likely than other companies to restructure their businesses if there are downturns in energy markets or in the global economy.

Utilities Sector Risk. Deregulation may subject utility companies to greater competition and may adversely affect their profitability. As deregulation allows utility companies to diversify outside of their original geographic regions and their traditional lines of business, utility companies may engage in riskier ventures. In addition, deregulation may eliminate restrictions on the profits of certain utility companies, but may also subject these companies to greater risk of loss. Companies in the utilities industry may have difficulty obtaining an adequate return on invested capital, raising capital, or financing large construction projects during periods of inflation or unsettled capital markets; face restrictions on operations and increased cost and delays attributable to environmental considerations and regulation; find that existing plants, equipment or products have been rendered obsolete by technological innovations; or be subject to increased costs because of the scarcity of certain fuels or the effects of man-made or natural disasters. Existing and future regulations or legislation may make it difficult for utility companies to operate profitably. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. There is no assurance that regulatory authorities will grant rate increases in the future or that such increases will be adequate to permit the payment of dividends on stocks issued by a utility company. Energy conservation and changes in climate policy may also have a significant adverse impact on the revenues and expenses of utility companies.

Principal Investment Strategies

The Fund seeks to track the investment results of the Russell Top 200^® Index (the “Underlying Index”), which measures the performance of the largest capitalization sector of the U.S. equity market, as defined by FTSE Russell (the “Index Provider” or “Russell”). The Underlying Index is a subset of the Russell 3000 Index, which measures the performance of the broad U.S. equity market, as defined by Russell. The Underlying Index is a float-adjusted capitalization-weighted index of equity securities issued by the approximately 200 largest issuers in the Russell 3000 Index. As of March 31, 2018, the Underlying Index represented approximately 62% of the total market capitalization of the Russell 3000 Index. Total market capitalization reflects all equity shares outstanding, while total market value reflects float-adjusted capitalizations based on equity shares available for general investment. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the financials and technology industries or sectors.

A Further Discussion of Principal Risks

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and

may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

underlying securities held by the Fund, particularly for newly launched or smaller funds or in instances of significant volatility of the underlying securities.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Dividends and Distributions

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, in which case your distributions generally

will be taxable when withdrawn, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

distribution requirements, but not in excess of the Fund’s earnings and profits, will be taxable to shareholders and will not constitute nontaxable returns of capital. The Fund’s capital loss carryforwards, if any, carried from taxable years beginning before 2011 do not reduce current earnings and profits, even if such carryforwards offset current year realized gains. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder's cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been

held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Any such capital gains, including from sales of Fund shares or from capital gain dividends, are included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Principal Investment Strategies

The Fund seeks to track the investment results of the Russell Top 200 Growth Index (the “Underlying Index”), which measures the performance of the largest capitalization growth sector of the U.S. equity market, as defined by FTSE Russell (the “Index Provider” or “Russell”). The Underlying Index is a subset of the Russell Top 200^® Index, which measures the performance of the largest capitalization sector of the U.S. equity market, as defined by Russell. As of March 31, 2018, the Underlying Index represented approximately 52% of the total market value of the Russell Top 200 Index. The Underlying Index measures the performance of equity securities of Russell Top 200 Index issuers with higher price-to-book ratios and higher forecasted growth relative to all securities included in the Russell Top 200 Index. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the consumer discretionary and technology industries or sectors. The components of the

Underlying Index are likely to change over time.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

A Further Discussion of Principal Risks

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and

may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

issuer may also be subject to risks associated with the countries, states and regions in which the issuer resides, invests, sells products, or otherwise conducts operations.

Market Trading Risk

advisable for investors who anticipate regularly making small investments through a brokerage account.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Utilities Sector Risk. Deregulation may subject utility companies to greater competition and may adversely affect their profitability. As deregulation allows utility companies to diversify outside of their original geographic regions and their traditional lines of business, utility companies may engage in riskier ventures. In addition, deregulation may eliminate restrictions on the profits of certain utility companies, but may also subject these companies to greater risk of loss. Companies in the utilities industry may have difficulty obtaining an adequate return on invested capital, raising capital, or financing large construction projects during periods of inflation or unsettled capital markets; face restrictions on operations and increased cost and delays attributable to environmental considerations and regulation; find that existing plants, equipment or products have been rendered obsolete by technological innovations; or be subject to increased costs because of the scarcity of certain fuels or the effects of man-made or natural disasters. Existing and future regulations or legislation may make it difficult for utility companies to operate profitably. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. There is no assurance that regulatory authorities will grant rate increases in the future or that such increases will be adequate to permit the payment of dividends on stocks issued by a utility company. Energy conservation and changes in climate policy may also have a significant adverse impact on the revenues and expenses of utility companies.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

iSHARES^® S&P 100 ETF

Ticker: OEF

Stock Exchange: NYSE Arca

Investment Objective

The iShares S&P 100 ETF (the “Fund”) seeks to track the investment results of an index composed of 100 large-capitalization U.S. equities.

Fees and Expenses

You may also incur usual and customary brokerage commissions and other charges when buying or selling shares of the Fund, which are not reflected in the Example that follows:

Annual Fund Operating Expenses (ongoing expenses that you pay each year as a percentage of the value of your investments)

S-1

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P 100^® (the “Underlying Index”), which measures the performance of the large-capitalization sector of the U.S. equity market. It is a subset of the S&P 500^® and consists of blue chip stocks from a broad range of industries in the S&P 500 with exchange listed options. As of March 31, 2018, the Underlying Index represented approximately 63% of the market capitalization of U.S. equities. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the information technology industry or sector. The components of the Underlying Index are likely to change over time.

S-2

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

Asset Class Risk. Securities and other assets in the Underlying Index or in the Fund's portfolio may underperform in comparison to the general financial

markets, a particular financial market or other asset classes.

S-3

Information Technology Sector Risk. Information technology companies face intense competition and potentially

rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by the loss or impairment of those rights.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

S-4

TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower

of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

The IOPV is based on the current market value of the securities or other assets and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities or other assets held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund's NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and price quotations obtained from broker-dealers and other market intermediaries that may trade in the portfolio securities or other assets held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the U.S. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

will be taxable when withdrawn, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

The components of the Underlying Index are likely to change over time.

The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

The spread, which varies over time for shares of the Fund based on trading volume and market liquidity, is generally narrower if the Fund has more trading volume and market liquidity and wider if the Fund has less trading volume and market liquidity. In addition, increased market volatility may cause wider spreads. There may also be regulatory and other charges that are incurred as a result of trading activity.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

iSHARES^® S&P MID-CAP 400 VALUE ETF

Ticker: IJJ

Stock Exchange: NYSE Arca

S-1

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P MidCap 400 Value Index^TM (the “Underlying Index”), which measures the performance of the mid-capitalization value sector of the U.S. equity market. It is a subset of the S&P MidCap 400^® and consists of those stocks in the S&P MidCap 400 exhibiting the strongest value characteristics, as determined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”), a subsidiary of S&P Global, Inc., representing approximately 47% of the market capitalization of the S&P MidCap 400 as of March 31, 2018. The stocks in the Underlying Index have a market capitalization between $1.4 billion and $5.9 billion (which may fluctuate depending on the overall level of the equity markets). The Underlying Index consists of stocks from a broad range of industries. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the financials and industrials industries or sectors. The

components of the Underlying Index are likely to change over time.

S-2

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

trading price, yield, total return and ability to meet its investment objective.

S-3

technology malfunctions and failures have become increasingly frequent in this sector and have caused significant losses to companies in this sector, which may negatively impact the Fund.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

S-4

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Risk of Investing in the United States. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on

the securities to which the Fund has exposure.

Market Trading Risk

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

engage in, transactions involving countries with less developed regulatory regimes or a history of expropriation, nationalization or other adverse policies. Energy companies also face a significant risk of liability from accidents resulting in injury or loss of life or property, pollution or other environmental problems, equipment malfunctions or mishandling of materials and a risk of loss from terrorism, political strife or natural disasters. Any such event could have serious consequences for the general population of the affected area and could have an adverse impact on the Fund’s portfolio and the performance of the Fund. Energy companies can be significantly affected by the supply of, and demand for, specific products (e.g., oil and natural gas) and services, exploration and production spending, government subsidization, world events and general economic conditions. Energy companies may have relatively high levels of debt and may be more likely than other companies to restructure their businesses if there are downturns in energy markets or in the global economy.

Materials Sector Risk. Companies in the materials sector may be adversely affected by commodity price volatility, exchange rates, import controls, increased competition,

depletion of resources, technical advances, labor relations, over-production, litigation and government regulations, among other factors. Companies in the materials sector are also at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

Real Estate Investment Risk. The Fund may invest in companies that invest in real estate (“Real Estate Companies”), such as real estate investment trusts (“REITs”), real estate holding companies, or real estate management or development companies, which expose investors to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which Real Estate Companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments and is characterized by intense competition and periodic overbuilding. Many Real Estate Companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially increase the Fund’s losses. Rising interest rates could result in higher costs of capital for Real Estate Companies, which could negatively affect a Real Estate Company's ability to meet its payment obligations or its financing activity, and could decrease the market prices for REITs and for properties held by such REITs. In addition, to the extent a Real Estate Company has its own expenses, the Fund (and indirectly, its shareholders) will bear its proportionate share of such expenses.

Repayment Risk. The prices of Real Estate Company securities may drop because of the failure of borrowers to repay their loans, poor management, or the inability to

U.S. Tax Risk. Certain U.S. Real Estate Companies are subject to special U.S. federal tax requirements. A REIT that fails to comply with such tax requirements may be subject to U.S. federal income taxation, which may affect the value of the REIT and the characterization of the REIT's distributions. The U.S. federal tax requirement that a REIT distributes substantially all of its net income to its shareholders may result in the REIT having insufficient capital for future expenditures. A REIT that successfully maintains its qualification may still become subject to U.S. federal, state and local taxes, including excise, penalty, franchise, payroll, mortgage recording, and transfer taxes, both directly and indirectly through its subsidiaries.

Utilities Sector Risk. Deregulation may subject utility companies to greater competition and may adversely affect their profitability. As deregulation allows utility companies to diversify outside of their original geographic regions and their traditional lines of business, utility companies may engage in riskier ventures. In addition, deregulation may eliminate restrictions on the profits of certain utility companies, but may also subject these companies to greater risk of loss. Companies in the utilities industry may have difficulty obtaining an adequate return on invested capital, raising capital, or financing large construction projects during periods of inflation or unsettled capital markets; face restrictions on operations and increased cost and delays attributable to environmental considerations and regulation; find that existing plants, equipment or products have been rendered obsolete by technological innovations; or be subject to increased costs because of the scarcity of certain fuels or the effects of man-made or natural disasters. Existing and future regulations or legislation may make it difficult for utility companies to operate profitably. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. There is no assurance that regulatory authorities will grant rate increases in the future or that such increases will be adequate to permit the payment of dividends on stocks issued by a utility company. Energy conservation and changes in climate policy may also have a significant adverse impact on the revenues and expenses of utility companies.

Portfolio Holdings Information

Management

For its investment advisory services to the Fund, BFA is paid a management fee from the Fund calculated based on the average daily net assets of the Fund. The management fee is calculated as follows: 0.25% per annum of the net assets less than or equal to $5.0 billion, plus 0.24% per annum of the net assets over $5.0 billion, up to and including $7.5 billion, plus 0.23% per annum of the net assets over $7.5 billion, up to and including $10.0 billion, plus 0.21% per annum of the net assets in excess of $10.0 billion. Based on assets of the Fund as of March 31, 2018, for its investment advisory services to the Fund, BFA was paid a management fee from the Fund, as a percentage of the Fund’s average daily net assets, at the annual rate of 0.25%.

Dividends and Distributions

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, in which case your distributions generally

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P SmallCap 600 Growth Index^TM (the “Underlying Index”), which measures the performance of the small-capitalization growth sector of the U.S. equity market. It is a subset of the S&P SmallCap 600^® and consists of those stocks in the S&P SmallCap 600 exhibiting the strongest growth characteristics, as determined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”), a subsidiary of S&P Global, Inc., representing approximately 51% of the market capitalization of the S&P SmallCap 600 as of March 31, 2018. The stocks in the Underlying Index have a market capitalization between $400 million and $1.8 billion (which may fluctuate depending on the overall level of the equity markets). As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the health care, industrials and information technology industries or sectors. The components of the Underlying Index are likely to change over time.

Risk of Investing in the United States. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on

the securities to which the Fund has exposure.

be identified and corrected by the Index Provider for a period of time or at all, particularly where the indices are less commonly used as benchmarks by funds or managers. Therefore, gains, losses or costs associated with errors of the Index Provider or its agents will generally be borne by the Fund and its shareholders. For example, during a period where the Underlying Index contains incorrect constituents, the Fund would have market exposure to such constituents and would be underexposed to the Underlying Index’s other constituents. Such errors may negatively or positively impact the Fund and its shareholders.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform

poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures, credit deterioration of the issuer or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline. An issuer may also be subject to risks associated with the countries, states and regions in which the issuer resides, invests, sells products, or otherwise conducts operations.

Market Trading Risk

advisable for investors who anticipate regularly making small investments through a brokerage account.

developments. Securities of small-capitalization companies may be thinly traded, making it difficult for the Fund to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making these companies more vulnerable to experiencing adverse effects due to the loss of personnel. Small-capitalization companies also normally have less diverse product lines than those of mid- or large-capitalization companies and are more susceptible to adverse developments concerning their products.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Financials Sector Risk. Companies in the financials sector of an economy are subject to extensive governmental regulation and intervention, which may adversely affect the

scope of their activities, the prices they can charge, the amount of capital they must maintain and, potentially, their size. The extent to which the Fund may invest in a company that engages in securities-related activities or banking is limited by applicable law. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financials sector, including effects not intended by such regulation. Recently enacted legislation in the U.S. has relaxed capital requirements and other regulatory burdens on certain U.S. banks. While the effect of the legislation may benefit certain companies in the financials sector, increased risk taking by affected banks may also result in greater overall risk in the financials sector. The impact of changes in capital requirements, or recent or future regulation in various countries, on any individual financial company or on the financials sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financials sector more severely than those of investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financials sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Insurance companies, in particular, may be subject to severe price competition and/or rate regulation, which may have an adverse impact on their profitability. The financials sector is particularly sensitive to fluctuations in interest rates. The financials sector is also a target for cyber attacks, and may experience technology malfunctions and disruptions. In recent years, cyber attacks and technology malfunctions and failures have become increasingly frequent in this sector and have reportedly caused losses to companies in this sector, which may negatively impact the Fund.

Real Estate Investment Risk. The Fund may invest in companies that invest in real estate (“Real Estate Companies”), such as real estate investment trusts (“REITs”), real estate holding companies, or real estate management or development companies, which expose investors to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which Real Estate Companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments and is characterized by intense competition and periodic overbuilding. Many Real Estate Companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially increase the Fund’s losses. Rising interest rates could result in higher costs of capital for Real Estate Companies, which could negatively affect a Real Estate Company's ability to meet its payment obligations or its financing activity, and could decrease the market prices for REITs and for properties held by such REITs. In addition, to the extent a Real Estate Company has its own expenses, the Fund (and indirectly, its shareholders) will bear its proportionate share of such expenses.

in certain of its properties and, consequently, its ability to control decisions relating to such properties may be limited.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Dividends and Distributions

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

companies are subject to extensive litigation based on product liability and similar claims. Healthcare companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the healthcare sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly, and such efforts ultimately may be unsuccessful. Companies in the healthcare sector may be thinly capitalized and may be susceptible to product obsolescence. In addition, a number of legislative proposals concerning healthcare have been considered by the U.S. Congress in recent years. It is unclear what proposals will ultimately be enacted, if any, and what effect they may have on companies in the healthcare sector.

Real Estate Investment Risk. The Fund may invest in companies that invest in real estate (“Real Estate Companies”), such as real estate investment trusts (“REITs”), real estate holding companies, or real estate management or development companies, which expose investors to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which Real Estate Companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments and is characterized by intense competition and periodic overbuilding. Many Real Estate Companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially increase the Fund’s losses. Rising interest rates could result in higher costs of capital for Real Estate Companies, which could negatively affect a Real Estate Company's ability to meet its payment obligations or its financing activity, and could decrease the market prices for REITs and for properties held by such REITs. In addition, to the extent a Real Estate Company has its own expenses, the Fund (and indirectly, its shareholders) will bear its proportionate share of such expenses.

Concentration Risk. Real Estate Companies may own a limited number of properties and concentrate their investments in a particular geographic region, industry or

property type. Economic downturns affecting a particular region, industry or property type may lead to a high volume of defaults within a short period.

Equity REITs Risk. The Fund may make direct investments in real estate. These REITs are often referred to as “Equity REITs.” Equity REITs invest primarily in real properties and may earn rental income from leasing those properties. Equity REITs may also realize gains or losses from the sale of properties. Equity REITs will be affected by conditions in the real estate rental market and by changes in the value of the properties they own. A decline in rental income may occur because of extended vacancies, limitations on rents, the failure to collect rents, increased competition from other properties or poor management. Equity REITs also can be affected by rising interest rates. Rising interest rates may cause investors to demand a high annual yield from future distributions that, in turn, could decrease the market prices for such REITs and for the properties held by such REITs. In addition, rising interest rates also increase the costs of obtaining financing for real estate projects. Because many real estate projects are dependent upon receiving financing, this could cause the value of the Equity REITs in which the Fund invests to decline.

the performance of the Underlying Index. This may increase the risk of the Fund being underinvested to the Underlying Index and increase the risk of tracking error.

Shareholder Information

not be viewed as a “real-time” update of the Fund's NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and price quotations obtained from broker-dealers and other market intermediaries that may trade in the portfolio securities or other assets held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the U.S. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Dividends and Distributions

taxable to you as long-term capital gains, regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates. Long-term capital gains and qualified dividend income are generally eligible for taxation at a maximum rate of 15% or 20% for non-corporate shareholders, depending on whether their income exceeds certain threshold amounts. In addition, a 3.8% U.S. federal Medicare contribution tax is imposed on “net investment income,” including, but not limited to, interest, dividends, and net gain, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly) and of estates and trusts.

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

authorized participant (an “Authorized Participant”) has entered into an agreement with the Fund's distributor, BlackRock Investments, LLC (the “Distributor”), an affiliate of BFA.

To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Approximate Value of a Creation Unit		Creation Unit Size		Standard Creation/ Redemption Transaction Fee		Maximum Additional Charge for Creations*		Maximum Additional Charge for Redemptions*

iSHARES^® U.S. AEROSPACE & DEFENSE ETF

Ticker: ITA

Stock Exchange: Cboe BZX

Principal Investment Strategies

The Fund seeks to track the investment results of the Dow Jones U.S. Select Aerospace & Defense Index (the “Underlying Index”), which measures the performance of the aerospace and defense sector of the U.S. equity market, as defined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). Aerospace companies in the Underlying Index include manufacturers, assemblers and distributors of aircraft and aircraft parts. Defense companies in the Underlying Index include producers of components and equipment for the defense industry, such as military aircraft, radar equipment and weapons. The Underlying Index may include
large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the aerospace and defense industries or sectors. The components of the Underlying Index are likely to change over time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s

S-2

Index, but which BFA believes will help the Fund track the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

The Underlying Index is sponsored by SPDJI which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

Summary of Principal Risks

Aerospace and Defense Industry Risk. The aerospace and defense

industry may be significantly affected by changes in government regulations and spending policies, changes in economic conditions and industry consolidation.

Cyber Security Risk. Failures or breaches of the electronic systems of the Fund, the Fund's adviser, distributor, and other service providers,

S-3

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

S-4

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the loaned securities fails to return

Management

For its investment advisory services to the Fund, BFA is paid a management fee from the Fund corresponding to the Fund's allocable portion of an aggregate management fee calculated based on the aggregate average daily net assets of the following iShares funds: iShares Transportation Average ETF, iShares U.S. Aerospace & Defense ETF, iShares U.S. Basic Materials ETF, iShares U.S. Broker-Dealers & Securities Exchanges ETF, iShares U.S. Consumer Goods ETF, iShares U.S. Consumer Services ETF, iShares U.S. Energy ETF, iShares U.S. Financial Services ETF, iShares U.S. Financials ETF, iShares U.S. Healthcare ETF, iShares U.S. Healthcare Providers ETF, iShares U.S. Home Construction ETF, iShares U.S. Industrials ETF, iShares U.S. Insurance ETF, iShares U.S. Medical Devices ETF, iShares U.S. Oil & Gas Exploration & Production ETF, iShares U.S. Oil Equipment & Services ETF, iShares U.S. Pharmaceuticals ETF, iShares U.S. Real Estate ETF, iShares U.S. Regional Banks ETF, iShares U.S. Technology ETF, iShares U.S. Telecommunications ETF and iShares U.S. Utilities ETF.

Based on assets of the iShares funds listed above as of March 31, 2018, for its investment advisory services to the Fund, BFA was paid a management fee from the Fund, as a percentage of the Fund's average daily net assets, at the annual rate of 0.43%.

Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Principal Investment Strategies

The Fund seeks to track the investment results of the Dow Jones U.S. Select Investment Services Index (the “Underlying Index”), which measures the performance of the investment services sector of the U.S. equity market, as defined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). The Underlying Index includes companies providing a range of specialized financial services, including securities brokers and dealers, online brokers and securities or commodities exchanges. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the financials industry or sector. The components of the Underlying Index are likely to change over time.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Changes in the financial

condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund's performance

may depend on the performance of a small number of issuers.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

The aggregate management fee is calculated as follows: 0.48% per annum of the aggregate net assets less than or equal to $10.0 billion, plus 0.43% per annum of the aggregate net assets over $10.0 billion, up to and including $20.0 billion, plus 0.38% per annum of the aggregate net assets over $20.0 billion, up to and including $30.0 billion, plus 0.34% per annum of the aggregate net assets over $30.0 billion, up to and including $40.0 billion, plus 0.33% per annum of the aggregate net assets over $40.0 billion, up to and including $50.0 billion, plus 0.31% per annum of the aggregate net assets in excess of $50.0 billion. Based on assets of the iShares funds listed above as of March 31, 2018, for its investment advisory services to the Fund, BFA was paid a management fee from the Fund, as a percentage of the Fund's average daily net assets, at the annual rate of 0.43%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired

fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Principal Investment Strategies

The Fund seeks to track the investment results of the Dow Jones U.S. Select Health Care Providers Index (the “Underlying Index”), which measures the performance of the healthcare providers sector of the U.S. equity market, as defined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). The Underlying Index includes companies that are healthcare providers, such as owners and operators of health maintenance organizations, hospitals, clinics, dental and eye care facilities, nursing homes and rehabilitation and retirement centers. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the healthcare industry or sector. The components of the Underlying Index are likely to change over time.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets

(including the value of any collateral received).

Summary of Principal Risks

Equity Securities Risk. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. The Underlying Index is

S-3

comprised of common stocks, which generally subject their holders to more risks than holders of preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Changes in the financial

condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the

S-4

Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and BFA seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

A Further Discussion of Principal Risks

common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Market Trading Risk

Risk of Investing in the United States. A decrease in imports or exports, changes in trade regulations and/or an economic recession in the U.S. may have a material

adverse effect on the U.S. economy and the securities listed on U.S. exchanges. Proposed and adopted policy and legislative changes in the U.S. are changing many aspects of financial and other regulation and may have a significant effect on the U.S. markets generally, as well as on the value of certain securities. In addition, a continued rise in the U.S. public debt level or U.S. austerity measures may adversely affect U.S. economic growth and the securities to which the Fund has exposure.

increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Portfolio Holdings Information

Fund fact sheets provide information regarding the Fund's top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

For its investment advisory services to the Fund, BFA is paid a management fee from the Fund corresponding to the Fund's allocable portion of an aggregate management fee calculated based on the aggregate average daily net assets of the following iShares funds: iShares Transportation Average ETF, iShares U.S. Aerospace & Defense ETF, iShares U.S. Basic Materials ETF, iShares U.S. Broker-Dealers & Securities Exchanges ETF, iShares U.S. Consumer Goods ETF, iShares U.S. Consumer Services ETF, iShares U.S. Energy ETF, iShares U.S. Financial Services ETF, iShares U.S. Financials ETF, iShares U.S. Healthcare ETF, iShares U.S. Healthcare Providers ETF, iShares U.S. Home Construction ETF, iShares U.S. Industrials ETF, iShares U.S. Insurance ETF, iShares U.S. Medical Devices ETF, iShares U.S. Oil & Gas Exploration & Production ETF, iShares U.S. Oil Equipment & Services ETF, iShares U.S. Pharmaceuticals ETF, iShares U.S. Real Estate ETF, iShares U.S. Regional Banks ETF, iShares U.S. Technology ETF, iShares U.S. Telecommunications ETF and iShares U.S. Utilities ETF. The aggregate management fee is calculated as follows: 0.48% per annum of the aggregate net assets less than or equal to $10.0 billion, plus 0.43% per annum of the aggregate net assets over $10.0 billion, up to and including $20.0 billion, plus 0.38% per annum of the aggregate net assets over $20.0 billion, up to and including $30.0 billion, plus 0.34% per annum of the aggregate net assets over $30.0 billion, up to and including $40.0 billion, plus 0.33% per annum of the aggregate net assets over $40.0 billion, up to and including $50.0 billion, plus 0.31% per annum of the aggregate net assets in excess of $50.0 billion. Based on assets of the iShares funds listed above as of March 31, 2018, for its investment advisory services to the Fund, BFA was paid a management fee from the Fund, as a percentage of the Fund's average daily net assets, at the annual rate of 0.43%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired

fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Principal Investment Strategies

The Fund seeks to track the investment results of the Dow Jones U.S. Select Home Construction Index (the “Underlying Index”), which measures the performance of the home construction sector of the U.S. equity market, as defined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). The Underlying Index includes companies that are constructors of residential homes, including manufacturers of mobile and prefabricated homes; manufacturers and distributors of furniture; retailers and wholesalers concentrating on the sale of home improvement products; and producers of materials used in the construction and refurbishment of buildings and structures. The companies selected for inclusion in the Underlying Index must meet minimum market capitalization and liquidity requirements. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the home

construction industry or sector. The components of the Underlying Index are likely to change over time.

S-2

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

A Further Discussion of Principal Risks

Home Construction Industry Risk. The home construction industry may be significantly affected by changes in government spending, zoning laws, general economic conditions, interest rates, commodity prices, consumer confidence and spending, taxation, demographic patterns, real estate values, overbuilding, housing starts, and new and existing home sales. Rising interest rates, reductions in mortgage availability to consumers, increasing foreclosure rates or increases in the costs of owning a home could reduce the market for new homes and adversely affect the profitability of home construction companies. Certain segments of the home construction industry can be significantly affected by environmental clean-up costs and catastrophic events such as earthquakes, hurricanes, tornadoes and terrorist acts. Home construction companies may lack diversification, due to ownership of a limited number of properties and concentration in a particular geographic region or property type.

Index may expose the Fund to additional tracking error risk, which is the risk that the Fund's returns may not track those of the Underlying Index. Therefore, errors and additional ad hoc rebalances carried out by the Index Provider or its agents to the Underlying Index may increase the costs to and the tracking error risk of the Fund.

Market Trading Risk

requirements for listing or trading on any exchange or in any market. The Fund's shares may be less actively traded in certain markets than in others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Management

and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

For its investment advisory services to the Fund, BFA is paid a management fee from the Fund corresponding to the Fund's allocable portion of an aggregate management fee calculated based on the aggregate average daily net assets of the following iShares funds: iShares Transportation Average ETF, iShares U.S. Aerospace & Defense ETF, iShares U.S. Basic Materials ETF, iShares U.S. Broker-Dealers & Securities Exchanges ETF, iShares U.S. Consumer Goods ETF, iShares U.S. Consumer Services ETF, iShares U.S. Energy ETF, iShares U.S. Financial Services ETF, iShares U.S. Financials ETF, iShares U.S. Healthcare ETF, iShares U.S. Healthcare Providers ETF, iShares U.S. Home Construction ETF, iShares U.S. Industrials ETF, iShares U.S. Insurance ETF, iShares U.S. Medical Devices ETF, iShares U.S. Oil & Gas Exploration & Production ETF, iShares U.S. Oil Equipment & Services ETF, iShares U.S. Pharmaceuticals ETF, iShares U.S. Real Estate ETF, iShares U.S. Regional Banks ETF, iShares U.S. Technology ETF, iShares U.S. Telecommunications ETF and iShares U.S. Utilities ETF. The aggregate management fee is calculated as follows: 0.48% per annum of the aggregate net assets less than or equal to $10.0 billion, plus 0.43% per annum of the aggregate net assets over $10.0 billion, up to and including $20.0 billion, plus 0.38% per annum of the aggregate net assets over $20.0 billion, up to and including $30.0 billion, plus 0.34% per annum of the aggregate net assets over $30.0 billion, up to and including $40.0 billion, plus 0.33% per annum of the aggregate net assets over $40.0 billion, up to and including $50.0 billion, plus 0.31% per annum of the aggregate net assets in excess of $50.0 billion. Based on assets of the iShares funds listed above as of March 31, 2018, for its investment advisory services to the Fund, BFA was paid a management fee from the Fund, as a percentage of the Fund's average daily net assets, at the annual rate of 0.43%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Alan Mason has been employed by BFA as a portfolio manager since 1991. Mr. Mason has been a Portfolio Manager of the Fund since 2016.

activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA or one or more of the other Affiliates acts, or may act, as an investor, investment banker, research provider, investment manager, commodity pool operator, commodity trading advisor, financier, underwriter, adviser, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests in securities, currencies, commodities, derivatives and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA or an Affiliate performs or seeks to perform investment banking or other services. Specifically, the Fund may invest in securities of, or engage in other transactions with, companies with which an Affiliate has developed or is trying to develop investment banking relationships or in which an Affiliate has significant debt or equity investments or other interests. The Fund also may invest in securities of, or engage in other transactions with, companies for which an Affiliate provides or may in the future provide research coverage. An Affiliate may have business relationships with, and purchase, distribute or sell services or products from or to, distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates in connection with the Fund's portfolio investment transactions.

The Fund's activities may be limited because of regulatory restrictions applicable to one or more Affiliates and/or their internal policies designed to comply with such restrictions.

Shareholder Information

a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities or other assets held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund's NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and price quotations obtained from broker-dealers and other market intermediaries that may trade in the portfolio securities or other assets held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the U.S. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

is likely to cause a material change to the closing market price of one or more assets or liabilities held by the Fund.

Dividends and Distributions

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities

lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains, if any, in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates. Long-term capital gains and qualified dividend income are generally eligible for taxation at a maximum rate of 15% or 20% for non-corporate shareholders, depending on whether their income exceeds certain threshold amounts. In addition, a 3.8% U.S. federal Medicare contribution tax is imposed on “net investment income,” including, but not limited to, interest, dividends, and net gain, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly) and of estates and trusts.

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

capital gain dividends, are included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Approximate Value of a Creation Unit		Creation Unit Size		Standard Creation/ Redemption Transaction Fee		Maximum Additional Charge for Creations*		Maximum Additional Charge for Redemptions*
$1,923,000		50,000		$250		3.0%		2.0%

*	As a percentage of the net asset value per Creation Unit, inclusive, in the case of redemptions, of the standard redemption transaction fee.

Principal Investment Strategies

The Fund seeks to track the investment results of the NYSE^® FactSet U.S. Infrastructure Index (the “Underlying Index”), which is designed to measure the performance of equity securities of U.S. companies involved in U.S. focused infrastructure activities (as determined by ICE Data Indices, LLC or its affiliates (the “Index Provider” or “IDI”)).

The Underlying Index is composed of equity securities primarily listed on the New York Stock Exchange (“NYSE”), NYSE American or NASDAQ (excluding master limited partnerships (MLPs), royalty trusts, business development companies (BDCs), and American depository receipts (ADRs)) that are classified to be under one of the 95 infrastructure-related industries as defined by FactSet Revere Business Industry Classification System (“RBICS”). Each company in the Underlying Index is classified as either Category 1 or Category 2, where Category 1 companies are infrastructure enablers and Category 2 are infrastructure asset owners and operators.

Infrastructure enablers are potential beneficiaries of infrastructure investment in the U.S. Category 1

companies in the Underlying Index include companies in construction and engineering services, machineries and materials. Infrastructure asset owners and operators are companies associated with traditional equity infrastructure investing. Category 2 companies in the Underlying Index include companies in energy transportation and storage, railroad transportation, and utilities.

At the time of inclusion, eligible companies must derive 50% or more of their annual revenues from the U.S. The Underlying Index applies equal weighting to Category 1 and Category 2, and within each category, equal weighting is also applied to all individual securities.

The Underlying Index will be reviewed and reconstituted annually in March each year. Constituent weights of the Underlying Index are rebalanced quarterly. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the capital goods, industrials, materials, non-energy materials, and utilities industries or sectors. The components of the Underlying Index are likely to change over time.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may

S-2

reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

The Underlying Index is sponsored by IDI, which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. RBICS is an industry classification system defined by FactSet Research Systems, Inc., which has full discretion over the classification system and is not affiliated with the Index Provider, the Fund or BFA. The classification methodology utilized for RBICS combines both market-defined information and a bottom-up approach to classify companies from all economic sectors and industries, including those in the infrastructure industry. RBICS's assignment for companies is reviewed at least once a year, with corporate actions being monitored on an ongoing basis.

More Information About the Fund

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

shares, and other data integral to the functioning of the Fund inaccessible or inaccurate or incomplete. Substantial costs may be incurred by the Fund in order to resolve or prevent cyber incidents in the future. While the Fund has established business continuity plans in the event of, and risk management systems to prevent, such cyber attacks, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified and that prevention and remediation efforts will not be successful. Furthermore, the Fund cannot control the cyber security plans and systems put in place by service providers to the Fund, issuers in which the Fund invests, the Index Provider, market makers or Authorized Participants. The Fund and its shareholders could be negatively impacted as a result.

costs and market exposure arising from such portfolio rebalancing will be borne directly by the Fund and its shareholders. Unscheduled rebalances to the Underlying Index may expose the Fund to additional tracking error risk, which is the risk that the Fund's returns may not track those of the Underlying Index. Therefore, errors and additional ad hoc rebalances carried out by the Index Provider or its agents to the Underlying Index may increase the costs to and the tracking error risk of the Fund.

Infrastructure Industry Risk. Companies in the infrastructure industry may be subject to a variety of factors that could adversely affect their business or operations, including high interest costs in connection with capital construction programs, high degrees of leverage, costs associated with governmental, environmental and other regulations, the effects of economic slowdowns, increased competition from other providers of services, uncertainties concerning costs, the level of government spending on infrastructure projects, and other factors. Infrastructure companies may be adversely affected by commodity price volatility, changes in exchange rates, import controls, depletion of resources, technological developments, and labor relations. There is also the risk that corruption may negatively affect publicly funded infrastructure projects, especially in emerging markets, resulting in delays and cost overruns. Infrastructure issuers can be significantly affected by government spending policies because companies involved in this industry rely to a significant extent on U.S. and other government demand for their products.

Infrastructure companies in the oil and gas sector may be adversely affected by government regulation or world events in the regions that the companies operate (e.g., expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and repatriation of capital, military coups, social unrest, violence or labor unrest).

Interest Rate Risk. Rising interest rates could result in higher costs of capital for infrastructure companies, which could negatively impact their ability to meet payment obligations.

Leverage Risk. Infrastructure companies can be highly leveraged which increases investments risk and other risks normally associated with debt financing, and could adversely affect an infrastructure company’s operations and market value in periods of rising interest rates.

Market Trading Risk

Utilities Sector Risk. Deregulation may subject utility companies to greater competition and may adversely affect their profitability. As deregulation allows utility companies to diversify outside of their original geographic regions and their traditional lines of business, utility companies may engage in riskier ventures. In addition, deregulation may eliminate restrictions on the profits of certain utility companies, but may also subject these companies to greater risk of loss. Companies in the utilities industry may have difficulty obtaining an adequate return on invested capital, raising capital, or financing large construction projects during periods of inflation or unsettled capital markets; face restrictions on operations and increased cost and delays attributable to environmental considerations and regulation; find that existing plants, equipment or products have been rendered obsolete by technological innovations; or be subject to increased costs because of the scarcity of certain fuels or the effects of man-made or natural disasters. Existing and future regulations or legislation may make it difficult for utility companies to operate profitably. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. There is no assurance that regulatory authorities will grant rate increases in the future or that such increases will be adequate to permit the payment of dividends on stocks issued by a utility company. Energy conservation and changes in climate policy may also have a significant adverse impact on the revenues and expenses of utility companies.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Shareholder Information

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the NYSE (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Dividends and Distributions

will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. Distributions in excess of the Fund’s minimum distribution requirements, but not in excess of the Fund’s earnings and profits, will be taxable to shareholders and will not constitute nontaxable returns of capital. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder's cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Principal Investment Strategies

The Fund seeks to track the investment results of the Dow Jones U.S. Select Insurance Index (the “Underlying Index”), which measures the performance of the insurance sector of the U.S. equity market, as defined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”).

The components of the Underlying Index are likely to change over time.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Principal Investment Strategies

The Fund seeks to track the investment results of the Dow Jones U.S. Select Medical Equipment Index (the “Underlying Index”), which measures the performance of the medical equipment sector of the U.S. equity market, as defined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). The Underlying Index includes medical equipment companies, including manufacturers and distributors of medical devices such as magnetic resonance imaging (MRI) scanners, prosthetics, pacemakers, X-ray machines, and other nondisposable medical devices. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the healthcare and medical equipment industries or sectors. The components of the Underlying Index are likely to change over time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many

investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

S-2

the Fund track the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

Asset Class Risk. Securities and other assets in the Underlying Index or in the Fund's portfolio may underperform in

comparison to the general financial markets, a particular financial market or other asset classes.

S-3

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

S-4

Medical Equipment Industry Group Risk. Companies in the medical equipment industry group may be affected by the expiration of patents, litigation based on product liability, industry competition, product obsolescence and regulatory approvals, among other factors.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Risk of Investing in the United States. Certain changes in the U.S. economy, such as when the U.S. economy

weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Market Trading Risk

Medical Equipment Industry Group Risk. Companies in the medical equipment industry group may be heavily dependent on patent protection, and the expiration of patents may adversely affect the profitability of these companies. Companies in the medical equipment industry group may be subject to extensive litigation based on product liability and similar claims as well as competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. The profitability of some medical equipment companies may be dependent on a relatively limited number of products. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the medical equipment industry group are subject to regulatory approvals, and the process of obtaining such approvals may be long and costly.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

A Further Discussion of Principal Risks

Energy Exploration and Production Industry Risk. The profitability of companies in the energy exploration and production industry is related to worldwide energy prices and costs related to exploration and production. The energy industry is cyclical and highly dependent on commodity prices. Energy-related companies can be significantly affected by the supply of, and demand for, particular energy products (such as oil and

natural gas). Companies in the energy exploration and production industry may be adversely affected by natural disasters or other catastrophes. These companies may be at risk for environmental damage claims and other types of litigation. Companies in the energy exploration and production industry also may be adversely affected by changes in exchange rates, interest rates, economic conditions, tax treatment, government regulation and intervention, negative perception, efforts at energy conservation and world events in the regions in which the companies operate (e.g., expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and repatriation of capital, military coups, social unrest, violence or labor unrest). Companies in the energy exploration and production industry may have significant capital investments in, or engage in transactions involving, emerging market countries, which may heighten these risks.

Large-Capitalization Companies Risk. Large-capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions.

Market Trading Risk

extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market.

Oil and Gas Industry Risk. The profitability of companies in the oil and gas industry is related to worldwide energy prices, exploration costs and production spending. Companies in the oil and gas industry may be at risk for environmental damage claims and other types of litigation. Companies in the oil and gas industry may be adversely affected by: natural disasters or other catastrophes; changes in exchange rates or interest rates; prices for competitive energy services, economic conditions, tax treatment, or government regulation; government intervention; negative public perception; or unfavorable events in the regions where companies operate (e.g., expropriation, nationalization, confiscation of assets and property, imposition of restrictions on foreign investments or repatriation of capital, military coups, social or political unrest, violence or labor unrest). Companies in the oil and gas industry may have significant capital investments in, or engage in transactions involving, emerging market countries, which may heighten these risks. Companies that own or operate gas pipelines are subject to certain risks, including pipeline and equipment leaks and ruptures, explosions, fires, unscheduled downtime, transportation interruptions, discharges or releases of toxic or hazardous gases and other environmental risks.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell shares of mid-capitalization companies. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Principal Investment Strategies

The Fund seeks to track the investment results of the Dow Jones U.S. Select Oil Equipment & Services Index (the “Underlying Index”), which measures the performance of the oil equipment and services sector of the U.S. equity market, as defined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). The Underlying Index includes companies that are suppliers of equipment or services to oil fields and offshore platforms, such as drilling, exploration, seismic information services and platform construction. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the energy, oil and gas and oil equipment and services industries or sectors. The components of the Underlying Index are likely to change over time.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets

(including the value of any collateral received).

Summary of Principal Risks

Energy Sector Risk. The market value of securities in the energy sector may decline for many reasons, including, among others, changes in energy prices, energy supply and demand, government

cycles, the performance of large-capitalization companies has trailed the overall performance of the broader securities markets.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Oil Equipment and Services Sub-Industry Risk. Companies in the oil equipment and services sub-industry are affected by worldwide energy

prices, exploration and production costs. Companies in the oil equipment and services sub-industry may have significant operations in areas at risk for natural disasters, social unrest and environmental damage. These companies may also be at risk for increased government regulation and intervention, litigation, and negative publicity and public perception.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

conservation efforts, increased competition and technological advances. Companies in this sector may be subject to substantial government regulation and contractual fixed pricing, which may increase the cost of doing business and limit the earnings of these companies. A significant portion of the revenues of these companies may depend on a relatively small number of customers, including governmental entities and utilities. As a result, governmental budget constraints may have a material adverse effect on the stock prices of companies in this sector. Energy companies may also operate in, or engage in, transactions involving countries with less developed regulatory regimes or a history of expropriation, nationalization or other adverse policies. Energy companies also face a significant risk of liability from accidents resulting in injury or loss of life or property, pollution or other environmental problems, equipment malfunctions or mishandling of materials and a risk of loss from terrorism, political strife or natural disasters. Any such event could have serious consequences for the general population of the affected area and could have an adverse impact on the Fund’s portfolio and the performance of the Fund. Energy companies can be significantly affected by the supply of, and demand for, specific products (e.g., oil and natural gas) and services, exploration and production spending, government subsidization, world events and general economic conditions. Energy companies may have relatively high levels of debt and may be more likely than other companies to restructure their businesses if there are downturns in energy markets or in the global economy.

Market Trading Risk

Oil and Gas Industry Risk. The oil equipment and services sector, which the Underlying Index seeks to track, is a subsector of the oil and gas industry. The profitability of companies in the oil and gas industry is related to worldwide energy prices, exploration costs and production spending. Companies in the oil and gas industry may be at risk for environmental damage claims and other types of litigation. Companies in the oil and gas industry may be adversely affected by: natural disasters or other catastrophes; changes in exchange rates or interest rates; prices for competitive energy services, economic conditions, tax treatment, or government regulation; government intervention; negative public perception; or unfavorable events in the regions where companies operate (e.g., expropriation, nationalization, confiscation of assets and property, imposition of restrictions on foreign investments or repatriation of capital, military coups, social or political unrest, violence or labor unrest). Companies in the oil and gas industry may have significant capital investments in, or engage in transactions involving, emerging market countries, which may heighten

these risks. Companies that own or operate gas pipelines are subject to certain risks, including pipeline and equipment leaks and ruptures, explosions, fires, unscheduled downtime, transportation interruptions, discharges or releases of toxic or hazardous gases and other environmental risks.

Oil Equipment and Services Sub-Industry Risk. The profitability of companies in the oil equipment and services sub-industry is related to worldwide energy prices, exploration, and production spending. Companies in the oil equipment and services sub-industry may be adversely affected by natural disasters or other catastrophes, and may be at risk for environmental damage claims and other types of litigation. Companies in the oil equipment and services sub-industry may be adversely affected by changes in exchange rates, interest rates, economic conditions, tax treatment, imposition of import controls and increased competition, oil deposits, technological developments, labor relations, government regulation and intervention, negative perception and world events in the regions that the companies operate (e.g., expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and repatriation of capital, military coups, social unrest, violence or labor unrest). Companies in the oil equipment and services sub-industry may have significant capital investments in, or engage in transactions involving, emerging market countries, which may heighten these risks.

increased internal unrest and discord. If this trend were to continue, it may have an adverse impact on the U.S. economy and the issuers in which the Fund invests.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

contracts include agreements relating to swaps, currency forwards and other derivatives as well as repurchase agreements and securities lending agreements. The restrictions prevent the Fund from closing out a qualified financial contract during a specified time period if the counterparty is subject to resolution proceedings and prohibit the Fund from exercising default rights due to a receivership or similar proceeding of an affiliate of the counterparty. Implementation of these requirements may increase credit and other risks to the Fund.

Portfolio Holdings Information

Management

and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

For its investment advisory services to the Fund, BFA is paid a management fee from the Fund corresponding to the Fund's allocable portion of an aggregate management fee calculated based on the aggregate average daily net assets of the following iShares funds: iShares Transportation Average ETF, iShares U.S. Aerospace & Defense ETF, iShares U.S. Basic Materials ETF, iShares U.S. Broker-Dealers & Securities Exchanges ETF, iShares U.S. Consumer Goods ETF, iShares U.S. Consumer Services ETF, iShares U.S. Energy ETF, iShares U.S. Financial Services ETF, iShares U.S. Financials ETF, iShares U.S. Healthcare ETF, iShares U.S. Healthcare Providers ETF, iShares U.S. Home Construction ETF, iShares U.S. Industrials ETF, iShares U.S. Insurance ETF, iShares U.S. Medical Devices ETF, iShares U.S. Oil & Gas Exploration & Production ETF, iShares U.S. Oil Equipment & Services ETF, iShares U.S. Pharmaceuticals ETF, iShares U.S. Real Estate ETF, iShares U.S. Regional Banks ETF, iShares U.S. Technology ETF, iShares U.S. Telecommunications ETF and iShares U.S. Utilities ETF. The aggregate management fee is calculated as follows: 0.48% per annum of the aggregate net assets less than or equal to $10.0 billion, plus 0.43% per annum of the aggregate net assets over $10.0 billion, up to and including $20.0 billion, plus 0.38% per annum of the aggregate net assets over $20.0 billion, up to and including $30.0 billion, plus 0.34% per annum of the aggregate net assets over $30.0 billion, up to and including $40.0 billion, plus 0.33% per annum of the aggregate net assets over $40.0 billion, up to and including $50.0 billion, plus 0.31% per annum of the aggregate net assets in excess of $50.0 billion. Based on assets of the iShares funds listed above as of March 31, 2018, for its investment advisory services to the Fund, BFA was paid a management fee from the Fund, as a percentage of the Fund's average daily net assets, at the annual rate of 0.43%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Alan Mason has been employed by BFA as a portfolio manager since 1991. Mr. Mason has been a Portfolio Manager of the Fund since 2016.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

of the securities or other assets and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities or other assets held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund's NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and price quotations obtained from broker-dealers and other market intermediaries that may trade in the portfolio securities or other assets held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the U.S. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

judgment prior to or at the time of pricing the Fund’s assets or liabilities, that the event is likely to cause a material change to the closing market price of one or more assets or liabilities held by the Fund.

Dividends and Distributions

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

2011 do not reduce current earnings and profits, even if such carryforwards offset current year realized gains. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder's cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Any such capital gains, including from sales of Fund shares or from capital gain dividends, are included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

not a “qualified institutional buyer,” as such term is defined in Rule 144A under the 1933 Act, will not be able to receive restricted securities eligible for resale under Rule 144A.

The Fund seeks to track the investment results of the Dow Jones U.S. Select Pharmaceuticals Index (the “Underlying Index”), which measures the performance of the pharmaceuticals sector of the U.S. equity market, as defined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). The Underlying Index includes pharmaceutical companies such as manufacturers of prescription or over-the-counter drugs or vaccines, but excludes producers of vitamins. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the healthcare and pharmaceuticals industries or sectors. The components of the Underlying Index are likely to change over time.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund's performance

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less

total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

S-1

Principal Investment Strategies

The Fund seeks to track the investment results of the S&P U.S. Preferred Stock Index (the “Underlying Index”), which measures the performance of a select group of preferred stocks listed on the New York Stock Exchange (“NYSE”), NYSE Arca, Inc. (“NYSE Arca”), NYSE Amex, NASDAQ Global Select Market, NASDAQ Select Market or NASDAQ Capital Market. The Underlying Index does not seek to directly reflect the performance of the companies issuing the preferred stock. The Underlying Index includes issuances of preferred stocks with a market capitalization over $100 million that meet minimum price, liquidity, trading volume, maturity and other requirements determined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”), a subsidiary of S&P Global, Inc. The Underlying Index excludes certain issues of preferred stock, such as those that are issued by special ventures (e.g., toll roads or dam operators) or structured products and brand name products issued by financial institutions that are packaged securities linked to indices or other stocks. As of

March 31, 2018, the Underlying Index consisted of the securities of 149 issuers, of which 25 were non-U.S. issuers.

Although preferred stocks represent a partial ownership interest in a company, preferred stocks generally do not carry voting rights and have economic characteristics similar to fixed-income securities. Preferred stocks generally are issued with a fixed par value and pay dividends based on a percentage of that par value at a fixed or variable rate. Additionally, preferred stocks often have a liquidation value that generally equals the original purchase price of the preferred stock at the date of issuance. The Underlying Index may include many different categories of preferred stock, such as floating, variable and fixed-rate preferreds, fixed-to-floating rate preferreds, callable preferreds, convertible preferreds, cumulative and non-cumulative preferreds, trust preferreds or various other traditional and hybrid issues of preferred stock.

The Underlying Index may include large-, mid- or small-capitalization companies and includes preferred stocks of non-U.S. issuers. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the financials industry or sector. The components of the Underlying Index are likely to change over time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many

S-2

investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

when conditions warrant, however, the Fund may invest at least 80% of its assets in the component securities of the Underlying Index and may invest up to 20% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of BlackRock Cash Funds, as well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could

S-3

trail that of other investments. The Fund is subject to certain risks, including the principal risks noted below, any of which may adversely affect the Fund's net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units (as defined in the Purchase and Sale of Fund Shares section of this Prospectus (the “Prospectus”)), Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

Equity Securities Risk. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. The Underlying Index is comprised of preferred stocks, holders of which generally are subject to more risks than debt securities because preferred stockholders’ claims are subordinated to those of holders of debt securities upon the bankruptcy of the issuer.

Financials Sector Risk. Performance of companies in the financials sector may be adversely impacted by many factors, including, among others, changes in government regulations, economic

S-4

conditions, and interest rates, credit rating downgrades, and decreased liquidity in credit markets. The extent to which the Fund may invest in a company that engages in securities-related activities or banking is limited by applicable law. A fund that invests in preferred securities may be more likely to be impacted by such legal limits since companies in the financials sector have historically issued a significant portion of the preferred securities marketplace. Moreover, such legal limits are more likely to impact the Fund's investments in preferred securities of financials sector issuers given the amount of net assets available for the Fund to invest. The impact of changes in capital requirements and recent or future regulation of any individual financial company, or of the financials sector as a whole, cannot be predicted. In recent years, cyber-attacks and technology malfunctions and failures have become increasingly frequent in this sector and have caused significant losses to companies in this sector, which may negatively impact the Fund.

Fixed-to-Floating Rate Securities Risk. The Fund invests in fixed-to-floating rate preferred securities, which are securities that have an initial term with a fixed dividend rate and following this initial term bear a floating dividend rate. Securities which include a floating or variable interest rate component can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. Although floating rate preferred securities can be less sensitive to interest rate risk than fixed-rate preferred securities, they are

subject to the risks applicable to preferred securities more generally.

Hybrid Securities Risk. Hybrid securities are subject to the risks of equity securities and risks of debt securities. The claims of holders of hybrid securities of an issuer are generally subordinated to those of holders of traditional debt securities in bankruptcy, and thus hybrid securities may be more volatile and subject to greater risk than traditional debt securities, and may in certain circumstances even be more volatile than traditional equity securities. At the same time, hybrid securities may not fully participate in gains of their issuer and thus potential returns of such securities are generally more limited than traditional equity securities, which would participate in such gains.

Interest Rate Risk. An increase in interest rates may cause the value of securities held by the Fund to decline, may lead to heightened volatility in the preferred securities market and may

S-5

adversely affect the liquidity of certain preferred investments. The historically low interest rate environment, together with recent modest rate increases, heightens the risks associated with rising interest rates.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Money Market Instruments Risk. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund's assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objective. An investment in a money market fund is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any other government agency. It is possible to lose money by investing in a money market fund. Money market funds other than government money market funds or retail money market funds “float” their NAV instead of using a stable $1.00 per share price.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Preferred Stock Risk. Preferred stocks are subject not only to issuer-specific and market risks generally applicable to equity securities, but also risks

S-6

associated with fixed-income securities, such as interest rate risk. A company’s preferred stock, which may pay fixed or variable rates of return, generally pays dividends only after the company makes required payments to creditors, including vendors, depositors, counterparties, holders of its bonds and other fixed-income securities. As a result, the value of a company’s preferred stock will react more strongly than bonds and other debt to actual or perceived changes in the company’s financial condition or prospects. Preferred stock may be less liquid than many other types of securities, such as common stock, and generally has limited or no voting rights. In addition, preferred stock is subject to the risks that a company may defer or not pay dividends, and, in certain situations, may call or redeem its preferred stock or convert it to common stock. An issuer may decide to call its outstanding preferred stock in various environments based on its assessment of the relative cost of capital across the company’s capital structure. A market-wide increase in preferred stock being called may reduce the aggregate size of the preferred stock universe and the number of issuers with preferred stock outstanding. Such reductions may make it more challenging for the Fund to invest in the component securities of the Underlying Index, increasing the risk of the Fund being underinvested in the Underlying Index and thus increasing the risk of tracking error. To the extent that the Fund invests a substantial portion of its assets in convertible preferred stocks, declining common stock values may also cause the value of the Fund’s investments to decline.

Risk of Investing in the United States. Certain changes in the U.S. economy,

such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

More Information About the Fund

substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the FDIC or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened because ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that are less widely traded often involve greater settlement and operational issues and capital costs for Authorized Participants, which may limit the availability of Authorized Participants.

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than

the market as a whole, to the extent that the Fund's investments are concentrated in the securities of a particular issuer or issuers, country, region, market, industry, group of industries, sector or asset class. The Fund may be more adversely affected by the underperformance of those securities, may experience increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those securities than a fund that does not concentrate its investments.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes. The Underlying Index is comprised of preferred stocks, holders of which generally are subject to more risks than debt securities because preferred stockholders’ claims are subordinated to those of holders of debt securities upon the bankruptcy of the issuer.

Fixed-to-Floating Rate Securities Risk. The Fund invests in fixed-to-floating rate preferred securities, which are securities that have an initial term with a fixed dividend rate and following this initial term bear a floating dividend rate. Securities which include a floating or variable interest rate component can be less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. Conversely, floating rate securities will not generally increase in value if interest rates decline. A decline in interest rates may result in a reduction in income received from

floating rate securities held by the Fund and may adversely affect the value of the Fund’s shares. Generally, floating rate securities carry lower yields than similar fixed rate securities. The interest rate for a floating rate security resets or adjusts periodically by reference to a benchmark interest rate. The impact of interest rate changes on floating rate investments is typically mitigated by the periodic interest rate reset of the investments. Fixed-to-floating rate securities generally are subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such securities. Benchmark interest rates, such as the LIBOR, may not accurately track market interest rates. There is no guarantee or assurance that: (i) the Fund will be able to invest in a desired amount of fixed-to-floating rate securities, (ii) the Fund will be able to buy such securities at a desirable price, or (iii) floating rate securities in which it invests or seeks to invest will be actively traded. Any or all of the foregoing, should they occur, could negatively impact the Fund.

Hybrid Securities Risk. Hybrid securities are securities which contain characteristics of both a debt security and an equity security. Therefore, hybrid securities are subject to the risks of equity securities and risks of debt securities. The terms of hybrid instruments may vary substantially. The claims of holders of hybrid securities of an issuer are generally subordinated to those of holders of traditional debt securities in bankruptcy, and thus hybrid securities may be more volatile and subject to greater risk than traditional debt securities, and may in certain circumstances even be more volatile than traditional equity securities. At the same time, hybrid securities may not fully participate in gains of their issuer and thus potential returns of such securities are generally more limited than traditional equity securities, which would participate in such gains. Hybrid securities may also be more limited in their rights to participate in management decisions of an issuer (such as voting for the board of directors). Certain hybrid securities may be more thinly traded and less liquid than either publicly issued equity securities or debt securities, especially hybrid securities that are “customized” to meet the needs of particular investors, potentially making it difficult for the Fund to sell such securities at a favorable price or at all. Any of these features could cause a loss in market value of hybrid securities held by the Fund or otherwise adversely affect the Fund.

Market Trading Risk

Money Market Instruments Risk. The value of money market instruments may be affected by changing interest rates and by changes in the credit ratings of the investments. If a significant amount of the Fund's assets are invested in money market instruments, it will be more difficult for the Fund to achieve its investment objective. An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. It is possible to lose money by investing in a money market fund. Money market funds other than government money market funds or retail money market funds “float” their NAV instead of using a stable $1.00 per share price.

Extension Risk. During periods of rising interest rates, certain obligations will be paid off substantially more slowly than originally anticipated, and the value of those

securities may fall sharply, resulting in a decline to the Fund’s income and potentially in the value of the Fund’s investments.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of the Fund's investments.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

■	Lower levels of liquidity and market efficiency;
■	Greater securities price volatility;
■	Exchange rate fluctuations and exchange controls;
■	Less availability of public information about issuers;
■	Limitations on foreign ownership of securities;
■	Imposition of withholding or other taxes;
■	Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
■	Higher transaction and custody costs and delays in settlement procedures;
■	Difficulties in enforcing contractual obligations;
■	Lower levels of regulation of the securities markets;
■	Weaker accounting, disclosure and reporting requirements; and
■	Legal principles relating to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the U.S.

Real Estate Investment Risk. The Fund may invest in Real Estate Companies, such as real estate investment trusts (“REITs”), real estate holding companies, or real estate management or development companies, which expose investors to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which Real Estate Companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments and is characterized by intense competition and periodic overbuilding. Many Real Estate Companies, including REITs, utilize leverage (and some may be highly leveraged), which increases investment risk and the risk normally associated with debt financing, and could potentially increase the Fund’s losses. Rising interest rates could result in higher costs of capital for Real Estate Companies, which could negatively affect a Real Estate Company's ability to meet its payment obligations or its financing activity, and could decrease the market prices for REITs and for properties held by such REITs. In addition, to the extent a Real Estate Company has its own expenses, the Fund (and indirectly, its shareholders) will bear its proportionate share of such expenses.

U.S. Tax Risk. Certain U.S. Real Estate Companies are subject to special U.S. federal tax requirements. A REIT that fails to comply with such tax requirements may be subject to U.S. federal income taxation, which may affect the value of the REIT and the characterization of the REIT's distributions. The U.S. federal tax requirement that a REIT distributes substantially all of its net income to its shareholders may result in the REIT having insufficient capital for future expenditures. A REIT that successfully maintains its qualification may still become subject to U.S. federal, state and local taxes, including excise, penalty, franchise, payroll, mortgage recording, and transfer taxes, both directly and indirectly through its subsidiaries.

(including the Fund) to purchase or dispose of investments, or exercise rights or undertake business transactions, may be restricted by regulation or otherwise impaired. The capacity of the Fund to make investments in certain securities may be affected by the relevant threshold limits, and such limitations may have adverse effects on the liquidity and performance of the Fund’s portfolio holdings compared to the performance of the Underlying Index. This may increase the risk of the Fund being underinvested to the Underlying Index and increase the risk of tracking error.

Management

For its investment advisory services to the Fund, BFA is paid a management fee from the Fund calculated based on the aggregate average daily net assets of the following iShares funds: iShares Latin America 40 ETF, iShares MSCI Pacific ex Japan ETF, iShares Russell 2000 ETF, iShares Russell 2000 Growth ETF, iShares Russell 2000 Value ETF, iShares Select Dividend ETF and iShares U.S. Preferred Stock ETF. The management fee for the Fund equals the ratio of the Fund's net assets over the aggregate net assets of the above iShares funds multiplied by the amount calculated as follows: 0.4800% per annum of the aggregate net assets less than or equal to $46 billion, plus 0.4560% per annum of the aggregate net assets over $46 billion, up to and including $81 billion, plus 0.4332% per annum of the aggregate net assets over $81 billion, up to and including $111 billion, plus 0.4116% per annum of the aggregate net assets over $111 billion, up to and including $141 billion, plus 0.3910% of the aggregate net assets in excess of $141 billion. Based on the assets of the iShares funds listed above as of March 31, 2018, for its investment advisory services to the

Fund, BFA was paid a management fee from the Fund, as a percentage of the Fund's average daily net assets, at the annual rate of 0.48%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Alan Mason has been employed by BFA as a portfolio manager since 1991. Mr. Mason has been a Portfolio Manager of the Fund since 2016.

Shareholder Information

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the NYSE (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Dividends and Distributions

availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and

with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

Separately, a 30% withholding tax is currently imposed on U.S.-source dividends, interest and other income items and will be imposed on proceeds from the sale,

redemption or other disposition of property producing U.S.-source dividends and interest paid after December 31, 2018, to (i) foreign financial institutions, including non-U.S. investment funds, unless they agree to collect and disclose to the U.S. Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to (i) enter into agreements with the IRS that state that they will provide the IRS information, including the names, addresses and taxpayer identification numbers of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information concerning their account holders, or (ii) in the event that an applicable intergovernmental agreement and implementing legislation are adopted, provide local revenue authorities with similar account holder information. Other foreign entities may need to report the name, address, and taxpayer identification number of each substantial U.S. owner or provide certifications of no substantial U.S. ownership unless certain exceptions apply.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Investment Objective

The iShares U.S. Real Estate ETF (the “Fund”) seeks to track the investment results of an index composed of U.S. equities in the real estate sector.

Principal Investment Strategies

The Fund seeks to track the investment results of the Dow Jones U.S. Real Estate Index (the “Underlying Index”), which measures the performance of the real estate sector of the U.S. equity market, as defined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by real estate investment trusts (“REITs”). The components of the Underlying Index are likely to change over time.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security

selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

companies. During different market cycles, the performance of large-capitalization companies has trailed the overall performance of the broader securities markets.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

U.S. Tax Risk. Certain U.S. Real Estate Companies are subject to special U.S. federal tax requirements. A REIT that fails to comply with such tax requirements may be subject to U.S. federal income taxation, which may affect the value of the REIT and the characterization of the REIT's distributions. The U.S. federal tax requirement that a REIT distributes substantially all of its net income to its shareholders may result in the REIT having insufficient capital for future expenditures. A REIT that successfully maintains its qualification may still become subject to U.S. federal, state and local taxes, including excise, penalty, franchise, payroll, mortgage recording, and transfer taxes, both directly and indirectly through its subsidiaries.

rise in the U.S. public debt level or U.S. austerity measures may adversely affect U.S. economic growth and the securities to which the Fund has exposure.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Retail REIT Sub-Industry Risk. The Fund invests in Equity REITs that own and operate properties available for lease to retail companies. In addition to the risks related to REITs generally, investments in these retail REITs are especially sensitive to local and national economic cycles. During times of down cycles, retail REITs are subject to decreases in demand for retail rental properties, defaults by tenants, store closings, and declines in rental market rates resulting from unanticipated economic, legal, or technological developments. Retail REITs are also negatively impacted by retail company bankruptcies and restructuring as a result of, among other things, changes in consumer confidence and spending, intense competition, changes in demographics, and changes in consumer tastes and preferences.

Management

For its investment advisory services to the Fund, BFA is paid a management fee from the Fund corresponding to the Fund's allocable portion of an aggregate management fee calculated based on the aggregate average daily net assets of the following iShares funds: iShares Transportation Average ETF, iShares U.S. Aerospace & Defense ETF, iShares U.S. Basic Materials ETF, iShares U.S. Broker-Dealers & Securities Exchanges ETF, iShares U.S. Consumer Goods ETF, iShares U.S. Consumer Services ETF, iShares U.S. Energy ETF, iShares U.S. Financial Services ETF, iShares U.S. Financials ETF, iShares U.S. Healthcare ETF, iShares U.S. Healthcare Providers ETF, iShares U.S. Home Construction ETF, iShares U.S. Industrials ETF, iShares U.S. Insurance ETF, iShares U.S. Medical Devices ETF, iShares U.S. Oil & Gas Exploration & Production ETF, iShares U.S. Oil Equipment & Services ETF, iShares U.S. Pharmaceuticals ETF, iShares U.S. Real Estate ETF, iShares U.S. Regional Banks ETF, iShares U.S. Technology ETF, iShares U.S. Telecommunications ETF and iShares U.S. Utilities ETF. The aggregate management fee is calculated as follows: 0.48% per annum of the aggregate net assets less than or equal to $10.0 billion, plus 0.43% per annum of the aggregate net assets over $10.0 billion, up to and including $20.0 billion, plus 0.38% per annum of the aggregate net assets over $20.0 billion, up to and including $30.0 billion, plus 0.34% per annum of the aggregate net assets over $30.0 billion, up to and including $40.0 billion, plus 0.33% per annum of the aggregate net assets over $40.0 billion, up to and including $50.0 billion, plus 0.31% per annum of the aggregate net assets in excess of $50.0 billion. Based on assets of the iShares funds listed above as of March 31, 2018, for its investment advisory services to the Fund, BFA was paid a management fee from the Fund, as a percentage of the Fund's average daily net assets, at the annual rate of 0.43%. BFA may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses (excluding acquired fund fees and expenses, if any). Any such voluntary waiver or reimbursement may be eliminated by BFA at any time.

Shareholder Information

underlying securities held by the Fund, particularly for newly launched or smaller funds or in instances of significant volatility of the underlying securities.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Dividends and Distributions

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, in which case your distributions generally

will be taxable when withdrawn, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains, if any, in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, with a 25% capital gain tax rate to the extent attributable to 25% rate gain distributions received by the Fund from REITs, regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates. Long-term capital gains and qualified dividend income are generally eligible for taxation at a maximum rate of 15% or 20% for non-corporate shareholders, depending on whether their income exceeds certain threshold amounts. In addition, a 3.8% U.S. federal Medicare contribution tax is imposed on “net investment income,” including, but not limited to, interest, dividends, and net gain, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly) and of estates and trusts.

Fund’s capital loss carryforwards, if any, carried from taxable years beginning before 2011 do not reduce current earnings and profits, even if such carryforwards offset current year realized gains. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder's cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

U.S. real property or an interest in a U.S. real property holding corporation. The rule with respect to distributions and redemptions attributable to a REIT’s distribution to the Fund will not expire.

authorized participant (an “Authorized Participant”) has entered into an agreement with the Fund's distributor, BlackRock Investments, LLC (the “Distributor”), an affiliate of BFA.

To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Principal Investment Strategies

The Fund seeks to track the investment results of the Dow Jones U.S. Select Regional Banks Index (the “Underlying Index”), which measures the performance of the regional bank sector of the U.S. equity market, as defined by S&P Dow Jones Indices LLC (the “Index Provider” or “SPDJI”). The Underlying Index is a subset of the Dow Jones U.S. Bank Index (the “Parent Index”). Small and mid-size banks are selected for inclusion in the Underlying Index based on their relative three-year average total assets as a percentage of the three-year average total assets held by all banks in the Parent Index, as determined by SPDJI. As of March 31, 2018, each bank in the Underlying Index had three-year average total assets that represented less than 5% of the three-year average total assets held by all banks in the Parent Index. The Underlying Index may include large-, mid- or small-capitalization companies. As of March 31, 2018, a significant portion of the Underlying Index is represented by securities of companies in the financials industry or sector. The components of

the Underlying Index are likely to change over time.

The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).

Summary of Principal Risks

trading price, yield, total return and ability to meet its investment objective.

S-3

technology malfunctions and failures have become increasingly frequent in this sector and have caused significant losses to companies in this sector, which may negatively impact the Fund.

S-4

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Regional Bank Risk. Performance of small- and mid-sized regional banks may involve greater risk, more volatility and less liquidity than customarily is associated with investments in larger, more established banks. Regional bank securities may have returns that vary, sometimes significantly, from the overall securities market and/or the overall financials sector. The regional banking industry is highly competitive, and failure to maintain or increase market share may result in a decline in market value. Recently enacted legislation in the United States has relaxed capital requirements and other regulatory burdens on certain U.S. banks. While the effect of the legislation may benefit certain regional banks, increased risk taking by affected banks may also result in greater overall risk in the regional banking industry. The impact of changes in capital requirements and the regulation of banking activities by U.S. prudential authorities may also adversely impact the value of the securities included in the Underlying Index.

S-5

other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences, differences in transaction costs, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or interest, tax gains or losses, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

More Information About the Fund

substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

Financials Sector Risk. Companies in the banking industry of an economy are subject to extensive governmental regulation and intervention, which may adversely affect the scope of their activities, the prices they can charge, the amount of capital they must maintain and, potentially, their size. The extent to which the Fund may invest in a company that engages in securities-related activities or banking is limited by applicable law. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financials sector, including effects not intended by such regulation. Recently enacted legislation in the U.S. has relaxed capital requirements and other regulatory burdens on certain U.S. banks. While the effect of the legislation may benefit certain companies in the financials sector, increased risk taking by affected banks may also result in greater overall risk in the financials sector. The impact of changes in capital requirements, or recent or future regulation in various countries, on any individual financial company or on the financials sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financials sector more severely than those of investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financials sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Insurance companies, in particular, may be subject to severe price competition and/or rate regulation, which may have an adverse impact on their profitability. The financials sector is particularly sensitive to fluctuations in interest rates. The financials sector is also a target for cyber attacks, and may experience technology malfunctions and disruptions. In recent years, cyber attacks and technology malfunctions and failures have become increasingly frequent in this sector and have reportedly caused losses to companies in this sector, which may negatively impact the Fund.

Market Trading Risk

seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Regional Bank Risk. Performance of small- and mid-sized regional banks may involve greater risk, more volatility and less liquidity than customarily is associated with investments in larger, more established banks. The performance of regional banks may be tied to the economic performance of the region that they serve. Regional bank securities may have returns that vary, sometimes significantly, from the overall securities market and/or the overall financials sector. The regional banking industry is highly competitive and failure to maintain or increase market share may result in a decline in market value. The marketing and expansion strategies of many regional banks may place a significant strain on their management, financial controls, operations systems, personnel and other resources. There is no guarantee that these banks will effectively complete the improvements to their systems, procedures and controls necessary to support their future operations or rapid growth. Recently enacted legislation in the United States has relaxed capital requirements and other regulatory burdens on certain U.S. banks. While the effect of the legislation may benefit certain regional banks, increased risk taking by affected banks may also result in greater overall risk in the regional banking industry. The impact of changes in capital requirements and the regulation of banking activities by U.S. prudential authorities may also adversely impact the value of the securities referenced by the Underlying Index.

could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund. BlackRock Institutional Trust Company, N.A., the Fund's securities lending agent, will take into account the tax impact to shareholders of substitute payments for dividends when managing the Fund's securities lending program.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

(including the value of any collateral received).

Summary of Principal Risks

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The

Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units (as defined in the Purchase and Sale of Fund Shares section of the Prospectus), Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

S-3

Provider, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Issuer Risk. The performance of the Fund depends on the performance of

individual securities to which the Fund has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns.

Media Sub-Industry Risk. Companies in the media sub-industry may be affected by industry competition, substantial capital requirements, state and federal government regulations and obsolescence of certain media products

S-4

and services due to competition and changing consumer tastes and interests.

Passive Investment Risk. The Fund is not actively managed, and BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Market Trading Risk

Media Sub-Industry Risk. Companies in the media sub-industry may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology. Media companies are subject to risks that include cyclicality of revenues and earnings, a potential decrease in the discretionary income of targeted individuals, changing consumer tastes and interests, competition in the industry and the potential for increased state and federal regulation. Advertising spending is an important source of revenue for media companies. During economic downturns advertising spending typically decreases and as a result, media companies tend to generate less revenue.

economic growth and the securities to which the Fund has exposure.

Telecommunications Sector Risk. The domestic telecommunications market is characterized by increasing competition and regulation by various state and federal regulatory authorities. Companies in the telecommunications sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in developing new products and services using new technology. Technological innovations may make the products and services of certain telecommunications companies obsolete. Telecommunications providers are generally required to obtain franchises or licenses in order to provide services in a given location. Licensing and franchise rights in the telecommunications sector are limited, which may provide an advantage to certain participants. Limited availability of such rights, high barriers to market entry and regulatory oversight, among other factors, have led to consolidation of companies within the sector, which could lead to further regulation or other negative effects in the future.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Shareholder Information

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing, provided that (i) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers and (ii) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board.

Equity investments and other instruments for which market quotations are readily available, as well as investments in an underlying fund, if any, are valued at market

Dividends and Distributions

Dividends received by the Fund from a RIC generally are qualified dividend income only to the extent such dividend distributions are made out of qualified dividend income received by such RIC.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ. The Fund may, in certain circumstances, offer Creation Units partially or solely for cash.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities (including any portion of such securities for which cash may be

substituted) held by the Fund and a specified amount of cash. Except when aggregated in Creation Units, shares are not redeemable by the Fund.

Approximate Value of a Creation Unit		Creation Unit Size		Standard Creation/ Redemption Transaction Fee		Maximum Additional Charge for Creations*		Maximum Additional Charge for Redemptions*
$1,368,500		50,000		$250		3.0%		2.0%

*	As a percentage of the net asset value per Creation Unit, inclusive, in the case of redemptions, of the standard redemption transaction fee.

General Description of the Trust and the Fund

The Trust currently consists of more than 280 investment series or portfolios. The Trust was organized as a Delaware statutory trust on December 16, 1999 and is authorized to have multiple series or portfolios. The Trust is an open-end management investment company registered with the SEC under the 1940 Act. The offering of the Trust’s shares is registered under the Securities Act of 1933, as amended (the “1933 Act”). This SAI relates solely to the Fund.

The Fund is managed by BFA, an indirect wholly owned subsidiary of BlackRock, Inc., and generally seeks to track the investment results of the specific benchmark index identified in the Fund's Prospectus (the “Underlying Index”).

The Fund offers and issues shares at their net asset value per share (“NAV”) only in aggregations of a specified number of shares (each, a “Creation Unit”), generally in exchange for a designated portfolio of securities (including any portion of such securities for which cash may be substituted) included in its Underlying Index (the “Deposit Securities”), together with the deposit of a specified cash payment (the “Cash Component”). Shares of the Fund are listed and trade on NYSE Arca, Inc. (“NYSE Arca” or the “Listing Exchange”), a national securities exchange. Shares of the Fund are traded in the secondary market and elsewhere at market prices that may be at, above or below the Fund's NAV. Shares are redeemable only in Creation Units by Authorized Participants (as defined in the Portfolio Holdings Information section of this SAI), and, generally, in exchange for portfolio securities and a Cash Amount (as defined in the Redemption of Creation Units section of this SAI). Creation Units typically are a specified number of shares, generally 50,000 or multiples thereof.

The Trust reserves the right to permit or require that creations and redemptions of shares are effected fully or partially in cash and reserves the right to permit or require the substitution of Deposit Securities in lieu of cash. Shares may be issued in advance of receipt of Deposit Securities, subject to various conditions, including a requirement that the Authorized Participant maintain with the Trust a cash deposit equal to at least 105% and up to 115%, which percentage BFA may change from time to time, of the market value of the omitted Deposit Securities. The Trust may use such cash deposit at any time to purchase Deposit Securities. See the Creation and Redemption of Creation Units section of this SAI. Transaction fees and other costs associated with creations or redemptions that include a cash portion may be higher than the transaction fees and other costs associated with in-kind creations or redemptions. In all cases, conditions with respect to creations and redemptions of shares and fees will be limited in accordance with the requirements of SEC rules and regulations applicable to management investment companies offering redeemable securities.

Exchange Listing and Trading

A discussion of exchange listing and trading matters associated with an investment in the Fund is contained in the Shareholder Information section of the Fund's Prospectus. The discussion below supplements, and should be read in conjunction with, that section of the Prospectus.

Shares of the Fund are listed for trading, and trade throughout the day, on the Listing Exchange and in other secondary markets. Shares of the Fund may also be listed on certain non-U.S. exchanges. There can be no assurance that the requirements of the Listing Exchange necessary to maintain the listing of shares of the Fund will continue to be met. The Listing Exchange may, but is not required to, remove the shares of the Fund from listing if, among other things: (i) following the initial 12-month period beginning upon the commencement of trading of Fund shares, there are fewer than 50 record and/or beneficial owners of shares of the Fund for 30 or more consecutive trading days, (ii) the value of the Underlying Index on which the Fund is based is no longer calculated or available, or (iii) any other event shall occur or condition shall exist that, in the opinion of the Listing Exchange, makes further dealings on the Listing Exchange inadvisable. The Listing Exchange will also remove shares of the Fund from listing and trading upon termination of the Fund or in the event the Fund does not comply with the continuous listing standards of the Listing Exchange, as described in the Fund’s Prospectus.

As in the case of other publicly-traded securities, when you buy or sell shares of the Fund through a broker, you may incur a brokerage commission determined by that broker, as well as other charges.

or through other widely disseminated means, an updated indicative optimized portfolio value (“IOPV”) for the Fund as calculated by an information provider or market data vendor. The Trust is not involved in or responsible for any aspect of the calculation or dissemination of the IOPV and makes no representation or warranty as to the accuracy of the IOPV.

An IOPV has a securities component and a cash component. The securities values included in an IOPV are the values of the Deposit Securities for the Fund. While the IOPV reflects the current value of the Deposit Securities required to be deposited in connection with the purchase of a Creation Unit, it does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time because the current portfolio of the Fund may include securities that are not a part of the current Deposit Securities. Therefore, the Fund’s IOPV disseminated during the Listing Exchange trading hours should not be viewed as a real-time update of the Fund’s NAV, which is calculated only once a day.

The cash component included in an IOPV consists of estimated accrued interest, dividends and other income, less expenses. If applicable, each IOPV also reflects unhedged changes in currency exchange rates between the U.S. dollar and the applicable currency.

The Trust reserves the right to adjust the share prices of the Fund in the future to maintain convenient trading ranges for investors. Any adjustments would be accomplished through stock splits or reverse stock splits, which would have no effect on the net assets of the Fund or an investor's equity interest in the Fund.

Investment Strategies and Risks

The Fund seeks to achieve its investment objective by investing a substantial portion of its assets in one Underlying Fund, the iShares JPX-Nikkei 400 ETF. The Fund may also invest in securities and other instruments that comprise the Underlying Index and in investments that provide substantially similar exposure to securities in the Underlying Index. The Fund also seeks to track the currency hedging transactions embedded in the Underlying Index by entering into currency forward contracts. The Fund operates as an index fund and is not actively managed. Adverse performance of a security or currency hedging transaction in the Fund’s portfolio will ordinarily not result in the elimination of the security or currency hedging transaction from the Fund’s portfolio.

The Fund engages in representative sampling, which is investing in a sample of securities selected by BFA to have a collective investment profile similar to that of the securities or other instruments comprising the Underlying Index. Securities selected have aggregate investment characteristics (based on market capitalization and industry weightings), fundamental characteristics (such as return variability, earnings valuation and yield) and liquidity measures similar to those of the Underlying Index. A fund that uses representative sampling generally does not hold all of the securities that are in its underlying index.

Although the Fund does not seek leveraged returns, certain instruments used by the Fund may have a leveraging effect as described below.

The Underlying Index applies a methodology that sells forward the total value of the non-U.S. dollar denominated securities included in the Underlying Index at a one-month forward rate to effectively create a “hedge” against fluctuations in the relative value of the Japanese yen in relation to the U.S. dollar. The hedge is reset on a monthly basis. The Underlying Index is designed to have higher returns than an equivalent unhedged investment when the Japanese yen is weakening relative to the U.S. dollar. Conversely, the Underlying Index is designed to have lower returns than an equivalent unhedged investment when the Japanese yen is rising relative to the U.S. dollar.

In order to track the “hedging” component of the Underlying Index, the Fund intends to enter into foreign currency forward contracts designed to offset the Fund’s exposure to the Japanese yen. A foreign currency forward contract is an over-the-counter (“OTC”) contract between two parties, each of which is an eligible contract participant, as defined in the Commodity Exchange Act (the “CEA”), to buy or sell a specified amount of a specific currency in the future at an agreed-upon exchange rate. The Fund’s exposure to foreign currency forward contracts is based on the aggregate exposure of the Fund to the Japanese yen. While this approach is designed to minimize the impact of currency fluctuations on Fund returns, it does not necessarily eliminate the Fund’s exposure to the Japanese yen. The return of the foreign currency forward contracts may not perfectly offset the actual fluctuations between the Japanese yen and the U.S. dollar.

The Fund may also use non-deliverable forward (“NDF”) contracts to execute its hedging transactions. NDFs are cash settled, short-term forward contracts that may be thinly traded or are denominated in non-convertible foreign currencies, where the profit or loss at the time of settlement date is calculated by taking the difference between the agreed-upon exchange rate and the spot rate at the time of settlement, for an agreed-upon notional amount of funds. NDFs generally have a fixing date and a settlement date. The fixing date is the valuation date at which the difference between the prevailing market exchange rate and the agreed-upon exchange rate is calculated. The settlement date is the date by which the payment of the difference is due to the party receiving payment. NDFs are commonly quoted for time periods ranging from one month to up to two years, and are normally quoted and settled in U.S. dollars. They are often used to gain exposure to and/or hedge exposure to foreign currencies that are not internationally traded.

Foreign currency forward contracts and NDFs are subject to regulation under The Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”) in the U.S. and under comparable regimes in Europe, Asia and other non-U.S. jurisdictions. Physically-settled forwards between eligible contract participants, such as the Fund, are generally subject to lighter regulation in the U.S. than NDFs and cash-settled foreign currency forward contracts. Under the Dodd-Frank Act, NDFs are regulated as swaps and are subject to rules requiring central clearing and mandatory trading on an exchange or facility that is regulated by the Commodity Futures Trading Commission (the “CFTC”). NDFs traded in the OTC market are subject to margin requirements that are expected to be finalized in the near future. Implementation of the regulations regarding clearing, mandatory trading and margining of NDFs are likely to increase the cost to the Fund of hedging currency risk and, as a result, may affect returns to investors in the Fund.

As a result of regulatory requirements under the 1940 Act, the Fund is required to maintain an amount of liquid assets, accrued on a daily basis, having an aggregate value at least equal to the value of the Fund’s obligations under the foreign currency forward contract or NDF. To the extent that foreign currency forward contracts are settled on a physical basis, the Fund will generally be required to maintain an amount of liquid assets equal to the notional value of the contract. In connection with NDFs and cash-settled foreign currency forward contracts, on the other hand, which are performed on a net basis, with the Fund receiving or paying only the net amount of a specified exchange rate, the Fund will generally maintain liquid assets, accrued daily, equal to the accrued excess, if any, of the Fund’s obligations over those of its counterparty under the contract. Accordingly, reliance by the Fund on physically-settled foreign currency forward contracts may adversely impact investors by requiring the Fund to set aside a greater amount of liquid assets than would generally be required if the Fund were relying on cash-settled foreign currency forward contracts or NDFs.

Set forth below is more detailed information regarding types of instruments in which the Fund or the Underlying Fund may invest, strategies BFA may employ in pursuit of the Fund’s or the Underlying Fund’s investment objective and related risks.

Borrowing. The Fund may borrow for temporary or emergency purposes, including to meet payments due from redemptions or to facilitate the settlement of securities or other transactions. Under normal market conditions, any borrowing by the Fund will not exceed 10% of the Fund’s net assets; however, the Fund generally does not intend to borrow money.

The purchase of securities while borrowings are outstanding may have the effect of leveraging the Fund. The incurrence of leverage increases the Fund’s exposure to risk, and borrowed funds are subject to interest costs that will reduce net income. Purchasing securities while borrowings are outstanding creates special risks, such as the potential for greater volatility in the net asset value of Fund shares and in the yield on the Fund’s portfolio. In addition, the interest expenses from borrowings may exceed the income generated by the Fund’s portfolio and, therefore, the amount available (if any) for distribution to shareholders as dividends may be reduced. BFA may determine to maintain outstanding borrowings if it expects that the benefits to the Fund’s shareholders will outweigh the current reduced return.

Certain types of borrowings by the Fund must be made from a bank or may result in the Fund being subject to covenants in credit agreements relating to asset coverage, portfolio composition requirements and other matters. It is not anticipated that observance of such covenants would impede BFA’s management of the Fund’s portfolio in accordance with the Fund’s investment objectives and policies. However, a breach of any such covenants not cured within the specified cure period may result in acceleration of outstanding indebtedness and require the Fund to dispose of portfolio investments at a time when it may be disadvantageous to do so.

Currency Transactions. A currency forward contract is an OTC obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days greater than two days from the date on which the contract is agreed upon by the parties, at a price set at the time of the contract. A non-deliverable currency forward is an OTC currency forward settled in a specified currency, on a specified date, based on the difference between the agreed-upon exchange rate and the market exchange rate. A currency futures contract is a contract that trades on an organized futures exchange involving an obligation to deliver or acquire a specified amount of a specific currency, at a specified price and at a specified future time. Currency futures contracts may be settled on a net cash payment basis rather than by the sale and delivery of the underlying currency. To the extent required by law, liquid assets committed to futures contracts will be maintained. The Fund expects to engage in currency transactions for the purpose of hedging against declines in the value of the Fund's assets that are denominated in a non-U.S. currency. The Fund may also enter into physically-settled non-U.S. currency forwards, and non-U.S. currency futures transactions and spot currency transactions to facilitate local securities settlements or to protect against currency exposure in connection with its distributions to shareholders. As described above, reliance on physically-settled foreign currency may require the Fund to set aside a greater amount of liquid assets than would generally be required if the fund were relying on cash-settled foreign currency forward contracts or NDFs. This would also generally be true if the Fund were to use other types of physically-settled currency contracts to track the Underlying Index, facilitate local securities settlements or protect against currency exposure.

Foreign exchange transactions may involve a significant degree of risk and the markets in which foreign exchange transactions are effected may be highly volatile, highly specialized and highly technical. Significant changes, including changes in liquidity and prices, can occur in such markets within very short periods of time, often within minutes. Foreign exchange trading risks include, but are not limited to, exchange rate risk, counterparty risk, maturity gap, interest rate risk, and potential interference by foreign governments through regulation of local exchange markets, foreign investment or particular transactions in non-U.S. currency. If BFA utilizes foreign exchange transactions at an inappropriate time or judges market conditions, trends or correlations incorrectly, foreign exchange transactions may not serve their intended purpose of improving the correlation of the Fund's return with the performance of its Underlying Index and may lower the Fund’s return. The Fund could experience losses if the value of its currency forwards and other currency transactions positions were poorly correlated with its other investments or with its other currency hedges or if it could not close out its positions because of an illiquid market or otherwise. In addition, the Fund could incur transaction costs, including trading commissions, in connection with non-U.S. currency transactions and costs related to investment opportunities due to the fact it will be required to set aside liquid assets equal to its obligations under its currency forwards in order to satisfy applicable requirements under the 1940 Act. Similarly, because the Fund seeks to hedge currency risk in accordance with the Underlying Index, investors will not share in appreciation in the securities comprising the Underlying Index to the extent that such appreciation is due to increases in the currency value of the underlying securities.

Derivatives. The Fund may use instruments referred to as derivatives. Derivatives are financial instruments the value of which is derived from another security, a commodity (such as gold or oil), a currency or an index (a measure of value or rates, such as the S&P 500 Index or the prime lending rate). Derivatives allow the Fund to increase or decrease the level of risk to which the Fund is exposed more quickly and efficiently than transactions in other types of instruments. The Fund may use derivatives for hedging purposes. The Fund may also use derivatives for speculative purposes to seek to enhance returns. The use of a derivative is speculative if the Fund is primarily seeking to achieve gains, rather than to offset the risk of other positions. When the Fund invests in a derivative for speculative purposes, the Fund will be fully exposed to the risks of loss of that derivative, which may sometimes be greater than the derivative’s cost. Unless otherwise permitted, the Fund may not use any derivatives to gain exposure to an asset or class of assets that it would be prohibited by its investment restrictions from purchasing directly.

Diversification Status. The Fund is classified as “non-diversified.” A non-diversified fund is a fund that is not limited by the 1940 Act with regard to the percentage of its assets that may be invested in the securities of a single issuer. The securities of a particular issuer (or securities of issuers in particular industries) may constitute a significant percentage of the underlying index of such a fund and, consequently, the fund’s investment portfolio. This may adversely affect the fund’s performance or subject the fund’s shares to greater price volatility than that experienced by more diversified investment companies.

The Fund intends to maintain the required level of diversification and otherwise conduct its operations so as to qualify as a regulated investment company (“RIC”) for purposes of the U.S. Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), and to relieve the Fund of any liability for U.S. federal income tax to the extent that its earnings are distributed to shareholders, provided that the Fund satisfies a minimum distribution requirement. Compliance with the diversification requirements of the Internal Revenue Code may limit the investment flexibility of the Fund and may make it less likely that the Fund will meet its investment objective.

Futures, Options on Futures and Securities Options. Futures contracts, options on futures and securities options may be used by the Fund to simulate investment in its Underlying Index, to facilitate trading or to reduce transaction costs. The Fund may enter into futures contracts and options on futures that are traded on a U.S. or non-U.S. futures exchange. The Fund does not currently intend to use futures, options on futures or securities options for speculative purposes. The Fund intends to use futures and options on futures in accordance with Rule 4.5 of the CFTC promulgated under the CEA. BFA, with respect to the Fund, has claimed an exclusion from the definition of the term “commodity pool operator” in accordance with Rule 4.5 so that BFA, with respect to the Fund, is not subject to registration or regulation as a commodity pool operator under the CEA. See the Regulation Regarding Derivatives section of this SAI for more information.

Futures contracts provide for the future sale by one party and purchase by another party of a specified amount of a specific instrument or index at a specified future time and at a specified price. Stock index contracts are based on investments that reflect the market value of common stock of the firms included in the investments. The Fund may enter into futures contracts to purchase securities indexes when BFA anticipates purchasing the underlying securities and believes prices will rise before the purchase will be made. Upon entering into a futures contract, the Fund will be required to deposit with the broker an amount of cash or cash equivalents known as “initial margin,” which is similar to a performance bond or good faith deposit on the contract and is returned to the Fund upon termination of the futures contract if all contractual obligations have been satisfied. Subsequent payments, known as “variation margin,” will be made to and from the broker daily as the price of the instrument or index underlying the futures contract fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as “marking-to-market.” At any time prior to the expiration of a futures contract, the Fund may elect to close the position by taking an opposite position, which will operate to terminate the Fund’s existing position in the contract. To the extent required by law, the Fund will segregate liquid assets in an amount equal to its delivery obligations under the futures contracts. An option on a futures contract, as contrasted with a direct investment in such a contract, gives the purchaser the right, but no obligation, in return for the premium paid, to assume a position in the underlying futures contract at a specified exercise price at any time prior to the expiration date of the option. Upon exercise of an option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer’s futures margin account that represents the amount by which the market price of the futures contract exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the futures contract. The potential for loss related to the purchase of an option on a futures contract is limited to the premium paid for the option plus transaction costs. Because the value of the option is fixed at the point of sale, there are no daily cash payments by the purchaser to reflect changes in the value of the underlying contract; however, the value of the option changes daily and that change would be reflected in the NAV of the Fund. The potential for loss related to writing call options is unlimited. The potential for loss related to writing put options is limited to the agreed-upon price per share, also known as the “strike price,” less the premium received from writing the put. The Fund may purchase and write put and call options on futures contracts that are traded on an exchange as a hedge against changes in value of its portfolio securities or in anticipation of the purchase of securities, and may enter into closing transactions with respect to such options to terminate existing positions. There is no guarantee that such closing transactions can be effected.

whether or not such option is exercised. The Fund may purchase put options to hedge its portfolio against the risk of a decline in the market value of securities held and may purchase call options to hedge against an increase in the price of securities it is committed to purchase. The Fund may write put and call options along with a long position in options to increase its ability to hedge against a change in the market value of the securities it holds or is committed to purchase. The Fund may purchase or sell securities options on a U.S. or non-U.S. securities exchange or in the OTC market through a transaction with a dealer. Options on a securities index are typically settled on a net basis based on the appreciation or depreciation of the index level over the strike price. Options on single name securities may be cash- or physically-settled, depending upon the market in which they are traded. Options may be structured so as to be exercisable only on certain dates or on a daily basis. Options may also be structured to have conditions to exercise (i.e., “Knock-in Events”) or conditions that trigger termination (i.e., “Knock-out Events”). Investments in futures contracts and other investments that contain leverage may require the Fund to maintain liquid assets in an amount equal to its delivery obligations under these contracts and other investments. Generally, the Fund maintains an amount of liquid assets equal to its obligations relative to the position involved, adjusted daily on a marked-to-market basis. With respect to futures contracts that are contractually required to “cash-settle,” the Fund maintains liquid assets in an amount at least equal to the Fund’s daily marked-to-market obligation (i.e., the Fund’s daily net liability, if any), rather than the contracts’ notional value (i.e., the value of the underlying asset). By maintaining assets equal to its net obligation under cash-settled futures contracts, the Fund may employ leverage to a greater extent than if the Fund were required to set aside assets equal to the futures contracts’ full notional value. The Fund bases its asset maintenance policies on methods permitted by the SEC and its staff and may modify these policies in the future to comply with any changes in the guidance articulated from time to time by the SEC or its staff. Changes in SEC guidance regarding the use of derivatives by registered investment companies may adversely impact the Fund’s ability to invest in futures, options or other derivatives or make investments in such instruments more expensive.

Hedging. Hedging is a strategy in which a derivative is used to offset particular risks associated with other Fund holdings. Losses on the other investment may be substantially reduced by gains on a derivative that reacts in an opposite manner to market movements. While hedging can reduce losses, it can also reduce or eliminate gains or cause losses if the market moves in a manner different from that anticipated by the Fund or if the cost of the derivative outweighs the benefit of the hedge. Establishment of hedges, if not tailored properly or timed in accordance with market changes, may not be effective in meeting the Fund’s intended objectives. This is due to the fact that hedging also involves correlation risk, i.e., the risk that changes in the value of the derivative will not match those of the holdings being hedged as expected by the Fund, in which case any losses on the holdings being hedged may not be reduced or may be increased. In connection with its trading in foreign currency forward contracts, the Fund will contract with a foreign or domestic bank, foreign or domestic securities dealer or other intermediary, to make or take future delivery of a specified amount of a particular currency. Physically settled currency contracts are not subject to centralized clearing and trading requirements in the U.S. but may be in other jurisdictions. In the U.S., NDFs must be traded into foreign currency contracts on a regulated exchange or facility and cleared through a central counterparty (a “CCP”). The Fund may also be subject to position limits in respect to the contracts established by a regulatory authority or exchange. There are no limitations on daily price moves in such foreign currency forward contracts, and banks and dealers are not required to continue to make markets in such contracts. There have been periods during which certain banks or dealers have refused to quote prices for such foreign currency forward contracts or have quoted prices with an unusually wide spread between the price at which the bank or dealer is prepared to buy and that at which it is prepared to sell. Governmental imposition of credit controls might limit any such foreign currency forward contract trading. With respect to its trading of foreign currency forward contracts, if any, the Fund will be subject to the risk of bank or dealer failure and the inability of, or refusal by, a bank or dealer to perform with respect to such contracts or, in the case of cleared contracts, the refusal of a CCP to clear a contract that is subject to mandatory clearing. Any such default would deprive the Fund of any potential profit or force the Fund to cover its commitments for resale at the then market price and could result in a loss to the Fund. The cost to the Fund of engaging in foreign currency forward contracts varies with such factors as the currencies involved, the length of the contract period, whether the contract is cash settled and, thus, would be subject to posting and collection of margin in the U.S. and the market conditions then prevailing. The inability to close options and futures positions also could have an adverse impact on the Fund’s ability to hedge effectively its portfolio. There is also a risk of loss by the Fund of margin deposits or collateral in the event of bankruptcy of a broker or other intermediary with whom the Fund has an open position in a currency forward or NDF, a swap, an option, a futures contract, a related option or another hedging instrument.

Illiquid Securities. The Fund may invest up to an aggregate amount of 15% of its net assets in illiquid securities (calculated at the time of investment). Illiquid securities may include securities subject to contractual or other restrictions on resale and other instruments that lack readily available markets, as determined in accordance with SEC staff guidance. The liquidity of a

security relates to the ability to readily dispose of the security and the price to be obtained upon disposition of the security, which may be lower than the price that would be obtained for a comparable, more liquid security. Illiquid securities may trade at a discount to comparable, more liquid securities and the Fund may not be able to dispose of illiquid securities in a timely fashion or at their expected prices.

Investments in Underlying Funds and Other Investment Companies. To implement its strategy, the Fund may invest some or all of its assets in the Underlying Fund. The Underlying Fund generally invests directly in portfolio securities. The Fund and the Underlying Fund may also invest in other investment companies, including exchange-traded funds (commonly referred to as “ETFs”) that are not iShares ETFs, to the extent permitted by law.

Lending Portfolio Securities. The Fund may lend portfolio securities to certain borrowers that BFA determines to be creditworthy, including borrowers affiliated with BFA. The borrowers provide collateral that is maintained in an amount at least equal to the current market value of the securities loaned. No securities loan shall be made on behalf of the Fund if, as a result, the aggregate value of all securities loaned by the Fund exceeds one-third of the value of the Fund's total assets (including the value of the collateral received). The Fund may terminate a loan at any time and obtain the return of the securities loaned. The Fund receives, by way of substitute payment, the value of any interest or cash or non-cash distributions paid on the loaned securities that it would have received if the securities were not on loan.

With respect to loans that are collateralized by cash, the borrower may be entitled to receive a fee based on the amount of cash collateral. The Fund is typically compensated by the difference between the amount earned on the reinvestment of cash collateral and the fee paid to the borrower. In the case of collateral other than cash, the Fund is typically compensated by a fee paid by the borrower equal to a percentage of the market value of the loaned securities. Any cash collateral may be reinvested in certain short-term instruments either directly on behalf of the lending fund or through one or more joint accounts or money market funds, including those affiliated with BFA; such investments are subject to investment risk. Other investment companies in which the Fund invests can be expected to incur fees and expenses for operations, such as investment advisory and administration fees, that would be in addition to those incurred by the Fund.

The Fund conducts its securities lending pursuant to an exemptive order from the SEC permitting it to lend portfolio securities to borrowers affiliated with the Fund and to retain an affiliate of the Fund to act as securities lending agent. To the extent that the Fund engages in securities lending, BlackRock Institutional Trust Company, N.A. (“BTC”) acts as securities lending agent for the Fund, subject to the overall supervision of BFA. BTC administers the lending program in accordance with guidelines approved by the Trust's Board of Trustees (the “Board,” the trustees of which are the “Trustees”).

Securities lending involves exposure to certain risks, including operational risk (i.e., the risk of losses resulting from problems in the settlement and accounting process), “gap” risk (i.e., the risk of a mismatch between the return on cash collateral reinvestments and the fees the Fund has agreed to pay a borrower), and credit, legal, counterparty and market risk. If a securities lending counterparty were to default, the Fund would be subject to the risk of a possible delay in receiving collateral or in recovering the loaned securities, or to a possible loss of rights in the collateral. In the event a borrower does not return the Fund’s securities as agreed, the Fund may experience losses if the proceeds received from liquidating the collateral do not at least equal the value of the loaned security at the time the collateral is liquidated, plus the transaction costs incurred in purchasing replacement securities. This event could trigger adverse tax consequences for the Fund. The Fund could lose money if its short-term investment of the collateral declines in value over the period of the loan. Substitute payments for dividends received by the Fund for securities loaned out by the Fund will not be considered qualified dividend income. BTC will take into account the tax effects on shareholders caused by this difference in connection with the Fund’s securities lending program. Substitute payments received on tax-exempt securities loaned out will not be tax-exempt income.

Non-U.S. Securities. The Fund, either directly or through its investments in the Underlying Fund, intends to purchase publicly-traded common stocks of non-U.S. issuers. To the extent the Fund invests in stocks of non-U.S. issuers, the Fund's investment in such stocks may be in the form of American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) and European Depositary Receipts (“EDRs”) (collectively, “depositary receipts”). Depositary receipts are receipts, typically issued by a bank or trust issuer, which evidence ownership of underlying securities issued by a non-U.S. issuer. Depositary receipts may not necessarily be denominated in the same currency as their underlying securities. ADRs typically are issued by an American bank or trust company and evidence ownership of underlying securities issued by a foreign corporation. EDRs, which are sometimes referred to as Continental Depositary Receipts, are receipts issued in Europe, typically by foreign banks and trust companies, that evidence ownership of either foreign or domestic underlying securities.

GDRs are depositary receipts structured like global debt issues to facilitate trading on an international basis. Generally, ADRs, issued in registered form, are designed for use in the U.S. securities markets, and EDRs, issued in bearer form, are designed for use in European securities markets. GDRs are tradable both in the U.S. and in Europe and are designed for use throughout the world.

The Fund will not invest in any unlisted depositary receipt or any depositary receipt that BFA deems illiquid at the time of purchase or for which pricing information is not readily available. In general, depositary receipts must be sponsored, but the Fund may invest in unsponsored depositary receipts under certain limited circumstances.

Depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted. In addition to investment risks associated with the underlying issuer, depositary receipts expose the Fund to additional risks associated with the non-uniform terms that apply to depositary receipt programs, credit exposure to the depository bank and to the sponsors and other parties with whom the depository bank establishes the programs, currency risk and liquidity risk. Unsponsored programs, which are not sanctioned by the issuer of the underlying common stock, generally expose investors to greater risks than sponsored programs and do not provide holders with many of the shareholder benefits that come from investing in a sponsored depositary receipts.

Investing in the securities of non-U.S. issuers involves special risks and considerations not typically associated with investing in U.S. issuers. These include differences in accounting, auditing and financial reporting standards; the possibility of expropriation or confiscatory taxation; adverse changes in investment or exchange control regulations; political instability, which could affect U.S. investments in non-U.S. countries; and potential restrictions on the flow of international capital. Non-U.S. issuers may be subject to less governmental regulation than U.S. issuers. Moreover, individual non-U.S. economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rate of inflation, capital reinvestment, resource self-sufficiency and balance of payment positions.

Regulation Regarding Derivatives. The CFTC subjects advisers to registered investment companies to regulation by the CFTC if a fund that is advised by the adviser either (i) invests, directly or indirectly, more than a prescribed level of its liquidation value in CFTC-regulated futures, options and swaps (“CFTC Derivatives”), or (ii) markets itself as providing investment exposure to such instruments. The CFTC also subjects advisers to registered investment companies to regulation by the CFTC if the registered investment company invests in one or more commodity pools. NDFs and cash-settled currency forwards as well as futures, options on futures, currency options and swaps entered into by the Fund will be treated as CFTC Derivatives for these purposes, whereas physically-settled foreign currency forward contracts generally will not be treated as CFTC Derivatives. To the extent the Fund uses CFTC Derivatives, it intends to do so below such prescribed levels and intends not to market itself as a “commodity pool” or a vehicle for trading such instruments.

Derivative contracts, including, without limitation, swaps, currency forwards, and non-deliverable forwards, are subject to regulation under the Dodd-Frank Act in the U.S. and under comparable regimes in Europe, Asia and other non-U.S. jurisdictions. Swaps, non-deliverable forwards and certain other derivatives traded in the OTC market are subject to variation margin requirements, and initial margining requirements will be phased in through 2020. Implementation of the margining and other provisions of the Dodd-Frank Act regarding clearing, mandatory trading, reporting and documentation of swaps and other derivatives have impacted and may continue to impact the costs to the Fund of trading in these instruments and, as a result, may affect returns to investors in the Fund.

As a result of regulatory requirements under the 1940 Act, the Fund is required to maintain an amount of liquid assets, accrued on a daily basis, having an aggregate value at least equal to the value of the Fund’s obligations under the applicable derivatives contract. To the extent that derivatives contracts are settled on a physical basis, the Fund will generally be required to maintain an amount of liquid assets equal to the notional value of the contract. On the other hand, in connection with derivatives contracts that are performed on a net basis, the Fund will generally be required to maintain liquid assets, accrued daily, equal only to the accrued excess, if any, of the Fund’s obligations over those of its counterparty under the contract. Accordingly, reliance by the Fund on physically-settled derivatives contracts may adversely impact investors by requiring the Fund to set aside a greater amount of liquid assets than would generally be required if the Fund were relying on cash-settled derivatives contracts.

Repurchase Agreements. A repurchase agreement is an instrument under which the purchaser (i.e., the Fund) acquires the security and the seller agrees, at the time of the sale, to repurchase the security at a mutually agreed-upon time and price, thereby determining the yield during the purchaser’s holding period. Repurchase agreements may be construed to be collateralized loans by the purchaser to the seller secured by the securities transferred to the purchaser. If a repurchase

agreement is construed to be a collateralized loan, the underlying securities will not be considered to be owned by the Fund but only to constitute collateral for the seller’s obligation to pay the repurchase price, and, in the event of a default by the seller, the Fund may suffer time delays and incur costs or losses in connection with the disposition of the collateral.

In any repurchase transaction, the collateral for a repurchase agreement may include: (i) cash items; (ii) obligations issued by the U.S. government or its agencies or instrumentalities; or (iii) obligations that, at the time the repurchase agreement is entered into, are determined to (A) have exceptionally strong capacity to meet their financial obligations and (B) are sufficiently liquid such that they can be sold at approximately their carrying value in the ordinary course of business within seven days.

Repurchase agreements pose certain risks for the Fund, should it decide to utilize them. Such risks are not unique to the Fund, but are inherent in repurchase agreements. The Fund seeks to minimize such risks, but because of the inherent legal uncertainties involved in repurchase agreements, such risks cannot be eliminated. Lower quality collateral and collateral with a longer maturity may be subject to greater price fluctuations than higher quality collateral and collateral with a shorter maturity. If the repurchase agreement counterparty were to default, lower quality collateral may be more difficult to liquidate than higher quality collateral. Should the counterparty default and the amount of collateral not be sufficient to cover the counterparty’s repurchase obligation, the Fund would likely retain the status of an unsecured creditor of the counterparty (i.e., the position the Fund would normally be in if it were to hold, pursuant to its investment policies, other unsecured debt securities of the defaulting counterparty) with respect to the amount of the shortfall. As an unsecured creditor, the Fund would be at risk of losing some or all of the principal and income involved in the transaction.

Reverse Repurchase Agreements. Reverse repurchase agreements involve the sale of securities with an agreement to repurchase the securities at an agreed-upon price, date and interest payment and have the characteristics of borrowing. Generally, the effect of such transactions is that the Fund can recover all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement, while in many cases the Fund is able to keep some of the interest income associated with those securities. Such transactions are advantageous only if the Fund has an opportunity to earn a rate of interest on the cash derived from these transactions that is greater than the interest cost of obtaining the same amount of cash. Opportunities to realize earnings from the use of the proceeds equal to or greater than the interest required to be paid may not always be available, and the Fund intends to use the reverse repurchase technique only when BFA believes it will be advantageous to the Fund. The use of reverse repurchase agreements may exaggerate any increase or decrease in the value of the Fund’s assets. The Fund’s exposure to reverse repurchase agreements will be covered by liquid assets having a value equal to or greater than the Fund’s obligations under such commitments. The use of reverse repurchase agreements is a form of leverage, and the proceeds obtained by the Fund through reverse repurchase agreements may be invested in additional securities.

Securities of Investment Companies. The Fund may invest in the securities of other investment companies (including money market funds) to the extent permitted by law. Pursuant to the 1940 Act, the Fund’s investment in registered investment companies is generally limited to, subject to certain exceptions: (i) 3% of the total outstanding voting stock of any one investment company; (ii) 5% of the Fund’s total assets with respect to any one investment company; and (iii) 10% of the Fund’s total assets with respect to investment companies in the aggregate. To the extent allowed by law or regulation, the Fund intends from time to time to invest their assets in the securities of investment companies, including, but not limited to, money market funds, including those advised by or otherwise affiliated with BFA, in excess of the general limits discussed above. Other investment companies in which the Fund may invest can be expected to incur fees and expenses for operations, such as investment advisory and administration fees, which would be in addition to those incurred by the Fund. Pursuant to guidance issued by the SEC staff, fees and expenses of money market funds used for cash collateral received in connection with loans of securities are not treated as Acquired Fund Fees and Expenses, which reflect the Fund’s pro rata share of the fees and expenses incurred by investing in other investment companies (as disclosed in the Prospectus, as applicable).

Short-Term Instruments and Temporary Investments. The Fund may invest in short-term instruments, including money market instruments, on an ongoing basis to provide liquidity or for other reasons. Money market instruments are generally short-term investments that may include, but are not limited to: (i) shares of money market funds (including those advised by BFA or otherwise affiliated with BFA); (ii) obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities (including government-sponsored enterprises); (iii) negotiable certificates of deposit, bankers’ acceptances, fixed-time deposits and other obligations of U.S. and non-U.S. banks (including non-U.S. branches) and similar institutions; (iv) commercial paper rated, at the date of purchase, “Prime-1” by Moody's^® Investors Service, Inc., “F-1” by Fitch Ratings, Inc., or “A-1” by Standard & Poor's^® Financial Services LLC, a subsidiary of S&P Global, Inc. (“S&P Global Ratings”), or if

unrated, of comparable quality as determined by BFA; (v) non-convertible corporate debt securities (e.g., bonds and debentures) with remaining maturities at the date of purchase of not more than 397 days and that have been determined to present minimal credit risks, in accordance with the requirements set forth in Rule 2a-7 under the 1940 Act; (vi) repurchase agreements; and (vii) short-term U.S. dollar-denominated obligations of non-U.S. banks (including U.S. branches) that, in the opinion of BFA, are of comparable quality to obligations of U.S. banks that may be purchased by the Fund. Any of these instruments may be purchased on a current or forward-settled basis. Time deposits are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates. Bankers’ acceptances are time drafts drawn on commercial banks by borrowers, usually in connection with international transactions.

Swap Agreements. Swap agreements are contracts between parties in which one party agrees to make periodic payments to the other party based on the change in market value or level of a specified rate, index or asset. In return, the other party agrees to make periodic payments to the first party based on the return of a different specified rate, index or asset. Swap agreements will usually be performed on a net basis, with the Fund receiving or paying only the net amount of the two payments. The net amount of the excess, if any, of the Fund’s obligations over its entitlements with respect to each swap is accrued on a daily basis, and an amount of liquid assets having an aggregate value at least equal to the accrued excess will be maintained by the Fund.

The Fund may enter into currency, interest rate or index swaps. The use of currency, interest rate and index swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. These transactions generally do not involve the delivery of securities or other underlying assets.

Tracking Stocks. A tracking stock is a separate class of common stock whose value is linked to a specific business unit or operating division within a larger company and is designed to “track” the performance of such business unit or division. The tracking stock may pay dividends to shareholders independent of the parent company. The parent company, rather than the business unit or division, generally is the issuer of tracking stock. However, holders of the tracking stock may not have the same rights as holders of the company’s common stock.

Future Developments. The Board may, in the future, authorize the Fund to invest in securities contracts and investments, other than those listed in this SAI and in the Prospectus, provided they are consistent with the Fund's investment objective and do not violate any of its investment restrictions or policies.

General Considerations and Risks

A discussion of some of the principal risks associated with an investment in the Fund is contained in the Prospectus. Because the Fund expects to obtain its exposure to the securities in the Underlying Index substantially through its investment in the Underlying Fund, shareholders should be aware that the risks of investment in particular types of securities, economic sectors and geographic locations discussed below may be borne by the Fund through its investment in the Underlying Fund. Through its investment in the Underlying Fund, the Fund will also bear the risks described below associated with the Underlying Fund’s use of portfolio management techniques, such as borrowing arrangements and use of derivatives, in addition to the risks associated with those activities if the Fund engages in them directly.

An investment in the Fund should be made with an understanding that the value of the Fund’s portfolio securities, including its investment in the Underlying Fund, may fluctuate in accordance with changes in the financial condition of the issuers of the portfolio securities, the value of stocks in general, and other factors that affect the market.

Borrowing Risk. Borrowing may exaggerate changes in the net asset value of Fund shares and in the return on the Fund’s portfolio. Borrowing will cost the Fund interest expense and other fees. The costs of borrowing may reduce the Fund’s return. Borrowing may cause the Fund to liquidate positions when it may not be advantageous to do so to satisfy its obligations.

problems. Practices in relation to the settlement of securities transactions in emerging markets involve higher risks than those in developed markets, in part because of the use of brokers and counterparties that are often less well capitalized, and custody and registration of assets in some countries may be unreliable. The possibility of fraud, negligence or undue influence being exerted by the issuer or refusal to recognize ownership exists in some emerging markets, and, along with other factors, could result in ownership registration being lost. In addition, the laws of certain countries may put limits on the Fund’s ability to recover its assets if a foreign bank or depository or issuer of a security or an agent of any of the foregoing goes bankrupt. The Fund would absorb any loss resulting from such custody problems and may have no successful claim for compensation.

Liquidity Risk Management Rule Risk. In October 2016, the SEC adopted a liquidity risk management rule requiring open-end funds, including ETFs such as the Fund, to establish a liquidity risk management program and enhance disclosures regarding fund liquidity. There are exclusions from certain portions of the liquidity risk management program requirements for “in-kind” ETFs . The Fund will be required to comply with portions of the rule by December 1, 2018. The effect the rule will have on the Fund, including the Fund’s ability to rely on the exclusions, is not yet known, but the rule may impact the Fund’s performance and ability to achieve its investment objective.

National Closed Market Trading Risk. To the extent that the underlying securities held by the Fund trade on foreign exchanges that are closed when the securities exchange on which the Fund’s shares trade is open, there are likely to be deviations between the current price of such an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations may result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other ETFs.

Operational Risk. BFA and the Fund's other service providers may experience disruptions or operating errors such as processing errors or human errors, inadequate or failed internal or external processes, or systems or technology failures, that could negatively impact the Fund. While service providers are required to have appropriate operational risk management policies and procedures, their methods of operational risk management may differ from the Fund’s in the setting of priorities, the personnel and resources available or the effectiveness of relevant controls. BFA, through its monitoring and oversight of service providers, seeks to ensure that service providers take appropriate precautions to avoid and mitigate risks that could lead to disruptions and operating errors. However, it is not possible for BFA or the other Fund service providers to identify all of the operational risks that may affect the Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects.

Risk of Derivatives. A derivative is a financial contract, the value of which depends on, or is derived from, the value of an underlying asset, such as a security, a commodity (such as gold or silver), a currency or an index (a measure of value or rates, such as the S&P 500^® or the prime lending rate). The Fund may invest in futures contracts, securities options and other derivatives. Compared to conventional securities, derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices and thus the Fund’s losses may be greater if it invests in derivatives than if it invests only in conventional securities. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations. Derivatives generally involve the incurrence of leverage. To address such leverage and to prevent the Fund from being deemed to have issued senior securities as a result of an investment in derivatives, the Fund will segregate liquid assets equal to its obligations under the derivatives throughout the life of the investment.

When a derivative is used as a hedge against a position that the Fund holds or is committed to purchase, any loss generated by the derivative generally should be substantially offset by gains on the hedged investment, and vice versa. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains and, in some cases, hedging can cause losses that are not offset by gains, and the Fund will recognize losses on both the investment and the hedge. Hedges are sometimes subject to imperfect matching between the derivative and the underlying security, and there can be no assurance that the Fund's hedging transactions, which entail additional transaction costs, will be effective.

and to increases and decreases in value as market confidence and perceptions of their issuers change. These investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies, inflation and interest rates, economic expansion or contraction, and global or regional political, economic or banking crises. Holders of common stocks incur more risks than holders of preferred stocks and debt obligations because common stockholders generally have rights to receive payments from stock issuers that are inferior to the rights of creditors, or holders of debt obligations or preferred stocks. Further, unlike debt securities, which typically have a stated principal amount payable at maturity (the value of which, however, is subject to market fluctuations prior to maturity), or preferred stocks, which typically have a liquidation preference and which may have stated optional or mandatory redemption provisions, common stocks have neither a fixed principal amount nor a maturity date. In addition, issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock price to decline.

Although most of the securities in the Underlying Index are listed on a securities exchange, the principal trading market for some of the securities may be in the OTC market. The existence of a liquid trading market for certain securities may depend on whether dealers will make a market in such securities. There can be no assurance that a market will be made or maintained or that any such market will be or remain liquid. The price at which securities may be sold and the value of the Fund’s shares will be adversely affected if trading markets for the Fund’s portfolio securities are limited or absent, or if bid/ask spreads are wide.

Risk of Futures and Options on Futures Transactions. There are several risks accompanying the utilization of futures contracts and options on futures contracts. A position in futures contracts and options on futures contracts may be closed only on the exchange on which the contract was made (or a linked exchange). While the Fund plans to utilize futures contracts only if an active market exists for such contracts, there is no guarantee that a liquid market will exist for the contract at a specified time. Futures contracts, by definition, project price levels in the future and not current levels of valuation; therefore, market circumstances may result in a discrepancy between the price of the future and the movement in the Fund's Underlying Index. In the event of adverse price movements, the Fund would continue to be required to make daily cash payments to maintain its required margin. In such situations, if the Fund has insufficient cash, it may have to sell portfolio securities to meet daily margin requirements at a time when it may be disadvantageous to do so. In addition, the Fund may be required to deliver the instruments underlying the futures contracts it has sold.

The risk of loss in trading futures contracts or uncovered call options in some strategies (e.g., selling uncovered stock index futures contracts) is potentially unlimited. The Fund does not plan to use futures and options contracts in this way. The risk of a futures position may still be large as traditionally measured due to the low margin deposits required. In many cases, a relatively small price movement in a futures contract may result in immediate and substantial loss or gain to the investor relative to the size of a required margin deposit.

Utilization of futures and options on futures by the Fund involves the risk of imperfect or even negative correlation to the Underlying Index if the index underlying the futures contract differs from the Underlying Index. There is also the risk of loss of margin deposits in the event of bankruptcy of a broker with whom the Fund has an open position in the futures contract or option. The purchase of put or call options will be based upon predictions by BFA as to anticipated trends, which predictions could prove to be incorrect.

Because the futures market generally imposes less burdensome margin requirements than the securities market, an increased amount of participation by speculators in the futures market could result in price fluctuations. Certain financial futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. The daily limit establishes the maximum amount by which the price of a futures contract may vary either up or down from the previous day’s settlement price at the end of a trading session. Once the daily limit has been reached in a particular type of contract, no trades may be made on that day at a price beyond that limit. It is possible that futures contract prices could move to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and subjecting the Fund to substantial losses. In the event of adverse price movements, the Fund would be required to make daily cash payments of variation margin.

Risk of Investing in Non-U.S. Equity Securities. An investment in the Fund involves risks similar to those of investing in portfolios of equity securities traded on non-U.S. exchanges. These risks include market fluctuations caused by such factors as economic and political developments in those foreign countries, changes in interest rates and perceived trends in stock prices. Investing in securities issued by issuers domiciled in countries other than the domicile of the investor and

denominated in currencies other than an investor’s local currency entails certain considerations and risks not typically encountered by the investor in making investments in its home country and in that country’s currency. These considerations include favorable or unfavorable changes in interest rates, currency exchange rates, exchange control regulations and the costs that may be incurred in connection with conversions between various currencies. Investing in the Fund also involves certain risks and considerations not typically associated with investing in a fund whose portfolio contains exclusively securities of U.S. issuers. These risks include generally less liquid and less efficient securities markets; generally greater price volatility; less publicly available information about issuers; the imposition of withholding or other taxes; the imposition of restrictions on the expatriation of funds or other assets of the Fund; higher transaction and custody costs; delays and risks attendant in settlement procedures; difficulties in enforcing contractual obligations; lower liquidity and significantly smaller market capitalization; different accounting and disclosure standards; lower levels of regulation of the securities markets; more substantial government interference with the economy and businesses; higher rates of inflation; greater social, economic, and political uncertainty; the risk of nationalization or expropriation of assets; and the risk of war.

Risk of Swap Agreements. The risk of loss with respect to swaps (including NDFs) is generally limited to the net amount of payments that the Fund is contractually obligated to make. Swap agreements are subject to the risk that the swap counterparty will default on its obligations. If such a default occurs, the Fund will have contractual remedies pursuant to the agreements related to the transaction. However, such remedies may be subject to bankruptcy and insolvency laws, which could affect the Fund’s rights as a creditor (e.g., the Fund may not receive the net amount of payments that it is contractually entitled to receive), which could result in the Fund losing the benefits of any hedging position.

The Fund is required to post and collect variation margin (comprised of specified liquid securities subject to haircuts) in connection with trading of OTC swaps. Implementation of regulations requiring posting of initial margin is being phased in through 2020. These requirements may raise the costs for the Fund’s investment in swaps.

Risk of Investing in Large-Capitalization Companies. Large-capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large-capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large-capitalization companies has trailed the overall performance of the broader securities markets.

Risk of Investing in Mid-Capitalization Companies. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies, and, therefore, the Fund’s share price may be more volatile than that of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it more difficult for the Fund to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments.

Risk of Investing in Small-Capitalization Companies. Stock prices of small-capitalization companies may be more volatile than those of larger companies, and, therefore, the Fund's share price may be more volatile than that of funds that invest a larger percentage of their assets in stocks issued by large-capitalization or mid-capitalization companies. Stock prices of small-capitalization companies are generally more vulnerable than those of large-capitalization or mid-capitalization companies to adverse business and economic developments. The stocks of small-capitalization companies may be thinly traded, making it difficult for the Fund to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making them more vulnerable to loss of personnel. Small-capitalization companies also normally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments concerning their products.

Risk of Investing in Asia. Investments in securities of issuers in certain Asian countries involve risks not typically associated with investments in securities of issuers in other regions. Such heightened risks include, among others, expropriation and/or nationalization of assets, confiscatory taxation, piracy of intellectual property, data and other security breaches (especially of data stored electronically), political instability, including authoritarian and/or military involvement in governmental decision-making, armed conflict and social instability as a result of religious, ethnic and/or socio-economic unrest. Certain Asian economies have experienced rapid rates of economic growth and industrialization in recent years, and there is no assurance that these rates of economic growth and industrialization will be maintained.

securities markets. Indonesia and the Philippines have each experienced violence and terrorism, which has negatively impacted their economies. North Korea and South Korea each have substantial military capabilities, and historical tensions between the two countries present the risk of war. Escalated tensions involving the two countries and any outbreak of hostilities between the two countries, or even the threat of an outbreak of hostilities, could have a severe adverse effect on the entire Asian region. Political, religious, and border disputes persist in India. India has recently experienced and may continue to experience civil unrest and hostilities with certain of its neighboring countries. Increased political and social unrest in these geographic areas could adversely affect the performance of investments in this region.

Certain governments in this region administer prices on several basic goods, including fuel and electricity, within their respective countries. Certain governments may exercise substantial influence over many aspects of the private sector in their respective countries and may own or control many companies. Future government actions could have a significant effect on the economic conditions in this region, which in turn could have a negative impact on private sector companies. There is also the possibility of diplomatic developments adversely affecting investments in the region.

Corruption and the perceived lack of a rule of law in dealings with international companies in certain Asian countries may discourage foreign investment and could negatively impact the long-term growth of certain economies in this region. In addition, certain countries in the region are experiencing high unemployment and corruption, and have fragile banking sectors.

Some economies in this region are dependent on a range of commodities, including oil, natural gas and coal. Accordingly, they are strongly affected by international commodity prices and particularly vulnerable to any weakening in global demand for these products. The market for securities in this region may also be directly influenced by the flow of international capital, and by the economic and market conditions of neighboring countries. Adverse economic conditions or developments in neighboring countries may increase investors' perception of the risk of investing in the region as a whole, which may adversely impact the market value of the securities issued by companies in the region.

Risk of Investing in Japan. Japan may be subject to political, economic, nuclear, labor and other risks. Any of these risks, individually or in the aggregate, can impact an investment made in Japan.

Economic Risk. The growth of Japan’s economy has recently lagged that of its Asian neighbors and other major developed economies. Since 2000, Japan’s economic growth rate has generally remained low relative to other advanced economies, and it may remain low in the future. The Japanese economy is heavily dependent on international trade and has been adversely affected by trade tariffs, other protectionist measures, competition from emerging economies and the economic conditions of its trading partners. Japan is also heavily dependent on oil imports, and higher commodity prices could therefore have a negative impact on the Japanese economy.

Political Risk. Historically, Japan has had unpredictable national politics and may experience frequent political turnover. Future political developments may lead to changes in policy that might adversely affect the Fund’s investments. In addition, China has become an important trading partner with Japan. Japan’s political relationship with China, however, has been strained. Should political tension increase, it could adversely affect the Japanese economy and destabilize the region as a whole.

Currency Risk. The Japanese yen has fluctuated widely at times and any increase in its value may cause a decline in exports that could weaken the Japanese economy. Japan has, in the past, intervened in the currency markets to attempt to maintain or reduce the value of the yen. Japanese intervention in the currency markets could cause the value of the yen to fluctuate sharply and unpredictably and could cause losses to investors.

Geographic Risk. Natural disasters, such as earthquakes, volcanic eruptions, typhoons and tsunamis, could occur in Japan or surrounding areas and could negatively affect the Japanese economy, and, in turn, could negatively affect the Fund.

U.S. Economic Trading Partners Risk. The U.S. is a significant, and in some cases the most significant, trading partner of, or foreign investor in, the country or countries in which the Fund invests. As a result, economic conditions of such countries may be particularly affected by changes in the U.S. economy. The U.S. economy has recently experienced very difficult conditions and increased volatility, as well as significant adverse trends. While government intervention and recent legislation has been enacted to improve the U.S. economy, the recovery has been fragile and modest. A decrease in U.S. imports, new trade and financial regulations, changes in the U.S. dollar exchange rate or an economic slowdown in the U.S. may have a material adverse effect on a country’s economic conditions and, as a result, securities to which the Fund has exposure.

Risk of Investing in the Consumer Discretionary Sector. Companies engaged in the design, production or distribution of products or services for the consumer discretionary sector (including, without limitation, television and radio broadcasting, manufacturing, publishing, recording and musical instruments, motion pictures, photography, amusement and theme parks, gaming casinos, sporting goods and sports arenas, camping and recreational equipment, toys and games, apparel, travel-related services, automobiles, hotels and motels, and fast food and other restaurants) are subject to the risk that their products or services may become obsolete quickly. The success of these companies can depend heavily on disposable household income and consumer spending. During periods of an expanding economy, the consumer discretionary sector may outperform the consumer staples sector, but may underperform when economic conditions worsen. Moreover, the consumer discretionary sector can be significantly affected by several factors, including, without limitation, the performance of domestic and international economies, exchange rates, changing consumer preferences, demographics, marketing campaigns, cyclical revenue generation, consumer confidence, commodity price volatility, labor relations, interest rates, import and export controls, intense competition, technological developments and government regulation.

Risk of Investing in the Consumer Staples Sector. Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. Companies in the consumer staples sector may also be affected by changes in global economic, environmental and political events, economic conditions, the depletion of resources, and government regulation. For instance, government regulations may affect the permissibility of using various food additives and production methods of companies that make food products, which could affect company profitability. In addition, tobacco companies may be adversely affected by the adoption of proposed legislation and/or by litigation. Companies in the consumer staples sector also may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The prices of raw materials fluctuate in response to a number of factors, including, without limitation, changes in government agricultural support programs, exchange rates, import and export controls, changes in international agricultural and trading policies, and seasonal and weather conditions. Companies in the consumer staples sector may be subject to severe competition, which may also have an adverse impact on their profitability.

Risk of Investing in the Financials Sector. Companies in the financials sector include regional and money center banks, securities brokerage firms, asset management companies, savings banks and thrift institutions, specialty finance companies (e.g., credit card, mortgage providers), insurance and insurance brokerage firms, consumer finance firms, financial conglomerates and foreign banking and financial companies.

Most financial companies are subject to extensive governmental regulation, which limits their activities and may affect their ability to earn a profit from a given line of business. Government regulation may change frequently and may have significant adverse consequences for companies in the financials sector, including effects not intended by the regulation. Direct governmental intervention in the operations of financial companies and financial markets may materially and adversely affect the companies in which the Fund invests, including legislation in many countries that may increase government regulation, repatriation and other intervention. The impact of governmental intervention and legislative changes on any individual financial company or on the financials sector as a whole cannot be predicted. The valuation of financial companies has been and continues to be subject to unprecedented volatility and may be influenced by unpredictable factors, including interest rate risk and sovereign debt default. Certain financial businesses are subject to intense competitive pressures, including market share and price competition. Financial companies in foreign countries are subject to market specific and general regulatory and interest rate concerns. In particular, government regulation in certain foreign countries may include taxes and controls on interest rates, credit availability, minimum capital requirements, bans on short sales, limits on prices and restrictions on currency transfers. In addition, companies in the financials sector may be the targets of hacking and potential theft of proprietary or customer information or disruptions in service, which could have a material adverse effect on their businesses.

The profitability of banks, savings and loan associations and financial companies is largely dependent on the availability and cost of capital funds and can fluctuate significantly when interest rates change; for instance, when interest rates go up, the value of securities issued by many types of companies in the financials sector generally goes down. In other words, financial companies may be adversely affected in certain market cycles, including, without limitation, during periods of rising interest rates, which may restrict the availability and increase the cost of capital, and during periods of declining economic conditions, which may cause, among other things, credit losses due to financial difficulties of borrowers.

In addition, general economic conditions are important to the operations of these companies, and financial difficulties of borrowers may have an adverse effect on the profitability of financial companies. Financial companies can be highly dependent upon access to capital markets, and any impediments to such access, such as adverse overall economic conditions or a negative perception in the capital markets of a financial company’s financial condition or prospects, could adversely affect its business. Deterioration of credit markets can have an adverse impact on a broad range of financial markets, causing certain financial companies to incur large losses. In these conditions, companies in the financials sector may experience significant declines in the valuation of their assets, take actions to raise capital and even cease operations. Some financial companies may also be required to accept or borrow significant amounts of capital from government sources and may face future government-imposed restrictions on their businesses or increased government intervention. In addition, there is no guarantee that governments will provide any such relief in the future. These actions may cause the securities of many companies in the financials sector to decline in value.

Risk of Investing in the Healthcare Sector. Companies in the healthcare sector are often issuers whose profitability may be affected by extensive government regulation, restrictions on government reimbursement for medical expenses, rising or falling costs of medical products and services, pricing pressure, an increased emphasis on outpatient services, a limited number of products, industry innovation, changes in technologies and other market developments. Many healthcare companies are heavily dependent on patent protection and the actual or perceived safety and efficiency of their products.

Patents have a limited duration, and, upon expiration, other companies may market substantially similar “generic” products that are typically sold at a lower price than the patented product, which can cause the original developer of the product to lose market share and/or reduce the price charged for the product, resulting in lower profits for the original developer. As a result, the expiration of patents may adversely affect the profitability of these companies.

companies offer products and services that are subject to governmental regulation and may be adversely affected by changes in governmental policies or laws. Changes in governmental policies or laws may span a wide range of topics, including cost control, national health insurance, incentives for compensation in the provision of healthcare services, tax incentives and penalties related to healthcare insurance premiums, and promotion of prepaid healthcare plans. In addition, a number of legislative proposals concerning healthcare have been considered by the U.S. Congress in recent years. It is unclear what proposals will ultimately be enacted, if any, and what effect they may have on companies in the healthcare sector.

Additionally, the expansion of facilities by healthcare-related providers may be subject to “determinations of need” by certain government authorities. This process not only generally increases the time and costs involved in these expansions, but also makes expansion plans uncertain, limiting the revenue and profitability growth potential of healthcare-related facilities operators and negatively affecting the prices of their securities. Moreover, in recent years, both local and national governmental budgets have come under pressure to reduce spending and control healthcare costs, which could both adversely affect regulatory processes and public funding available for healthcare products, services and facilities.

Risk of Investing in the Information Technology Sector. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face product obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Finally, while all companies may be susceptible to network security breaches, certain companies in the information technology sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses. These risks are heightened for information technology companies in foreign markets.

Risk of Investing in the Materials Sector. Companies in the materials sector may be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical progress, labor relations and government regulations, and mandated expenditures for safety and pollution control, among other factors. Companies in the materials sector are also at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns. These risks are heightened for companies in the materials sector located in foreign markets.

Risk of Investing in the Real Estate Industry. Companies in the real estate industry include companies that invest in real estate, such as real estate investment trusts (“REITs”), real estate holding companies or real estate development companies (collectively, “Real Estate Companies”). Investing in Real Estate Companies exposes investors to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which Real Estate Companies are organized and operated. The real estate industry is highly sensitive to general and local economic conditions and developments, and characterized by intense competition and periodic overbuilding. Investing in Real Estate Companies involves various risks. Some risks that are specific to Real Estate Companies are discussed in greater detail below.

Interest Rate Risk. Rising interest rates could result in higher costs of capital for Real Estate Companies, which could negatively impact a Real Estate Company’s ability to meet its payment obligations. Declining interest rates could result in increased prepayment on loans and require redeployment of capital in less desirable investments.

Leverage Risk. Real Estate Companies may use leverage (and some may be highly leveraged), which increases investment risk and could adversely affect a Real Estate Company’s operations and market value in periods of rising interest rates. Real Estate Companies are also exposed to the risks normally associated with debt financing. Financial covenants related to a Real Estate Company’s leverage may affect the ability of the Real Estate Company to operate effectively. In addition, real property may be subject to the quality of credit extended and defaults by borrowers and tenants. If the properties do not generate sufficient income to meet operating expenses, including, where applicable, debt service, ground lease payments, tenant improvements, third-party leasing commissions and other capital expenditures, the income and ability of a Real Estate Company to make payments of any interest and principal on its debt securities will be adversely affected.

Loan Foreclosure Risk. Real Estate Companies may foreclose on loans that the Real Estate Company originated or acquired. Foreclosure may generate negative publicity for the underlying property that affects its market value. In addition to length and expense, foreclosure proceedings may not fully uphold the validity of all of the terms of the applicable loan. Claims and defenses asserted by borrowers or other lenders may interfere with the enforcement of rights by a Real Estate Company. Parallel proceedings, such as bankruptcy, may also delay resolution and limit the amount of recovery on a foreclosed loan by a Real Estate Company even where the property underlying the loan is liquidated.

Property Risk. Real Estate Companies may be subject to risks relating to functional obsolescence or reduced desirability of properties; extended vacancies due to economic conditions and tenant bankruptcies; catastrophic events such as earthquakes, hurricanes and terrorist acts; and casualty or condemnation losses. Real estate income and values also may be greatly affected by demographic trends, such as population shifts or changing tastes and values, or increasing vacancies or declining rents resulting from legal, cultural, technological, global or local economic developments.

Distressed Investment Risk. Real Estate Companies may invest in distressed, defaulted or out-of-favor bank loans. Identification and implementation by a Real Estate Company of loan modification and restructure programs involves a high degree of uncertainty. Even successful implementation may still require adverse compromises and may not prevent bankruptcy. Real Estate Companies may also invest in other debt instruments that may become non-performing, including the securities of companies with higher credit and market risk due to financial or operational difficulties. Higher risk securities may be less liquid and more volatile than the securities of companies not in distress.

Underlying Investment Risk. Real Estate Companies make investments in a variety of debt and equity instruments with varying risk profiles. For instance, Real Estate Companies may invest in debt instruments secured by commercial property that have higher risks of delinquency and foreclosure than loans on single family homes due to a variety of factors associated with commercial property, including the tie between income available to service debt and productive use of the property. Real Estate Companies may also invest in debt instruments and preferred equity that are junior in an issuer’s capital structure and that involve privately negotiated structures. Subordinated debt investments, such as B-Notes and mezzanine loans, involve a greater credit risk of default due to the need to service more senior debt of the issuer. Similarly, preferred equity investments involve a greater risk of loss than conventional debt financing due to their non-collateralized nature and subordinated ranking. Investments in commercial mortgage-backed securities may also be junior in priority in the event of bankruptcy or similar proceedings. Investments in senior loans may be effectively subordinated if the senior loan is pledged as collateral. The ability of a holder of junior claims to proceed against a defaulting issuer is circumscribed by the terms of the particular contractual arrangement, which vary considerably from transaction to transaction.

Management Risk. Real Estate Companies are dependent upon management skills and may have limited financial resources. Real Estate Companies are generally not diversified and may be subject to heavy cash flow dependency, default by borrowers and voluntary liquidation. In addition, transactions between Real Estate Companies and their affiliates may be subject to conflicts of interest, which may adversely affect a Real Estate Company’s shareholders. A Real Estate Company may also have joint venture investments in certain of its properties, and, consequently, its ability to control decisions relating to such properties may be limited.

Liquidity Risk. Investing in Real Estate Companies may involve risks similar to those associated with investing in small-capitalization companies. Real Estate Company securities, like the securities of small-capitalization companies, may be more volatile than, and perform differently from, shares of large-capitalization companies. There may be less trading in Real Estate Company shares, which means that buy and sell transactions in those shares could have a magnified impact on share price, resulting in abrupt or erratic price fluctuations. In addition, real estate is relatively illiquid, and, therefore, a Real Estate Company may have a limited ability to vary or liquidate properties in response to changes in economic or other conditions.

Concentration Risk. Real Estate Companies may own a limited number of properties and concentrate their investments in a particular geographic region or property type. Economic downturns affecting a particular region, industry or property type may lead to a high volume of defaults within a short period.

Regulatory Risk. Real estate income and values may be adversely affected by such factors as applicable domestic and foreign laws (including tax laws). Government actions, such as tax increases, zoning law changes or environmental regulations, also may have a major impact on real estate income and values. In addition, quarterly compliance with regulations limiting the proportion of asset types held by a U.S. REIT may force certain Real Estate Companies to liquidate or restructure otherwise attractive investments. Some countries may not recognize REITs or comparable structures as a viable form of real estate funds.

Risk of Investing in the Telecommunications Sector. The telecommunications sector of a country’s economy is often subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new regulatory requirements may negatively affect the business of telecommunications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. Companies in the telecommunications sector may experience distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in developing new products and services using new technology. Technological innovations may make the products and services of certain telecommunications companies obsolete. Finally, while all companies may be susceptible to network security breaches, certain companies in the telecommunications sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.

Risk of Investing in the Utilities Sector. The utilities sector may be adversely affected by changing commodity prices, government regulation stipulating rates charged by utilities, increased tariffs, changes in tax laws, interest rate fluctuations and changes in the cost of providing specific utility services. The utilities industry is also subject to potential terrorist attacks, natural disasters and severe weather conditions, as well as regulatory and operational burdens associated with the operation and maintenance of nuclear facilities. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. In certain countries, regulatory authorities may also restrict a company’s access to new markets, thereby diminishing the company’s long-term prospects.

There are substantial differences among the regulatory practices and policies of various jurisdictions, and any regulatory agency may make major shifts in policy from time to time. There is no assurance that regulatory authorities will, in the future, grant rate increases. Additionally, existing and possible future regulatory legislation may make it even more difficult for utilities to obtain adequate relief. Certain of the issuers of securities held in the Fund's portfolio may own or operate nuclear generating facilities. Governmental authorities may from time to time review existing policies and impose additional requirements governing the licensing, construction and operation of nuclear power plants. Prolonged changes in climate conditions can also have a significant impact on both the revenues of an electric and gas utility as well as the expenses of a utility, particularly a hydro-based electric utility.

The rates that traditional regulated utility companies may charge their customers generally are subject to review and limitation by governmental regulatory commissions. Rate changes may occur only after a prolonged approval period or may not occur at all, which could adversely affect utility companies when costs are rising. The value of regulated utility debt securities (and, to a lesser extent, equity securities) tends to have an inverse relationship to the movement of interest rates. Certain utility companies have experienced full or partial deregulation in recent years. These utility companies are frequently more similar to industrial companies in that they are subject to greater competition and have been permitted by regulators to diversify outside of their original geographic regions and their traditional lines of business. As a result, some companies may be forced to defend their core business and may be less profitable. Deregulation may also permit a utility company to expand outside of its traditional lines of business and engage in riskier ventures.

Proxy Voting Policy

The Board has delegated the voting of proxies for the Fund’s securities to BFA pursuant to BFA’s proxy voting guidelines and procedures (the “BlackRock Proxy Voting Guidelines”). Under the BlackRock Proxy Voting Guidelines, BFA will vote proxies related to Fund securities in the best interests of the Fund and its shareholders. From time to time, a vote may present a conflict between the interests of the Fund’s shareholders, on the one hand, and those of BFA, or any affiliated person of the

Fund or BFA, on the other. BFA maintains policies and procedures that are designed to prevent undue influence on BFA’s proxy voting activity that might stem from any relationship between the issuer of a proxy (or any dissident shareholder) and BFA, BFA’s affiliates, the Fund or the Fund’s affiliates. Most conflicts are managed through a structural separation of BFA’s Corporate Governance Group from BFA’s employees with sales and client responsibilities. In addition, BFA maintains procedures to ensure that all engagements with corporate issuers or dissident shareholders are managed consistently and without regard to BFA’s relationship with the issuer of the proxy or the dissident shareholder. In certain instances, BFA may determine to engage an independent fiduciary to vote proxies as a further safeguard to avoid potential conflicts of interest or as otherwise required by applicable law. Copies of the Fund's Proxy Voting Policy and the BlackRock Proxy Voting Guidelines are attached as Appendix A.

Information with respect to how BFA voted proxies relating to the Fund's portfolio securities during the 12-month period ending June 30 will be available: (i) without charge, upon request, by calling 1-800-iShares (1-800-474-2737) or through the Fund's website at www.iShares.com; and (ii) on the SEC’s website at www.sec.gov.

Portfolio Holdings Information

The Board has adopted a policy regarding the disclosure of the Fund's portfolio holdings information that requires that such information be disclosed in a manner that: (i) is consistent with applicable legal requirements and in the best interests of the Fund’s shareholders; (ii) does not put the interests of BFA, the Distributor or any affiliated person of BFA or the Distributor, above those of Fund shareholders; (iii) does not advantage any current or prospective Fund shareholders over any other current or prospective Fund shareholders, except to the extent that certain Entities (as described below) may receive portfolio holdings information not available to other current or prospective Fund shareholders in connection with the dissemination of information necessary for transactions in Creation Units, as discussed below, and certain information may be provided to personnel of BFA and its affiliates who manage funds that invest a significant percentage of their assets in shares of the Fund for the purpose of facilitating risk management and hedging activities; and (iv) does not provide selective access to portfolio holdings information except pursuant to the procedures outlined below and to the extent appropriate confidentiality arrangements limiting the use of such information are in effect. The “Entities” referred to in sub-section (iii) above are generally limited to National Securities Clearing Corporation (“NSCC”) members, subscribers to various fee-based subscription services, large institutional investors (known as “Authorized Participants”) that have been authorized by the Distributor to purchase and redeem large blocks of shares pursuant to legal requirements and market makers and other institutional market participants and entities that provide information or transactional services.

Each business day, the Fund's portfolio holdings information will be provided to the Distributor or other agent for dissemination through the facilities of the NSCC and/or other fee-based subscription services to NSCC members and/or subscribers to those other fee-based subscription services, including market makers and Authorized Participants, and to entities that publish and/or analyze such information in connection with the process of purchasing or redeeming Creation Units or trading shares of the Fund in the secondary market or evaluating such potential transactions. This information typically reflects the Fund’s anticipated holdings on the following business day.

Daily access to information concerning the Fund's portfolio holdings is permitted: (i) to certain personnel of those service providers that are involved in portfolio management and providing administrative, operational, risk management, or other support to portfolio management; and (ii) to other personnel of the Fund's investment adviser, the Distributor and their affiliates, and the administrator, custodian and fund accountant who deal directly with, or assist in, functions related to investment management, distribution, administration, custody, securities lending and fund accounting, as may be necessary to conduct business in the ordinary course in a manner consistent with federal securities laws and regulations thereunder. In addition, the Fund discloses its fixed-income and/or equity portfolio holdings daily at www.iShares.com. More information about this disclosure is available at www.iShares.com.

Portfolio holdings information made available in connection with the creation/redemption process may be provided to other entities that provide services to the Fund in the ordinary course of business after it has been disseminated to the NSCC. From time to time, information concerning portfolio holdings other than portfolio holdings information made available in connection with the creation/redemption process, as discussed above, may be provided to other entities that provide services to the Fund, including rating or ranking organizations, in the ordinary course of business, no earlier than one business day following the date of the information.

The Fund will disclose its complete portfolio holdings schedule in public filings with the SEC within 70 days of the end of the second and fourth fiscal quarters and within 60 days of the end of the first and third fiscal quarters and will provide such information to shareholders as required by federal securities laws and regulations thereunder. The Fund may, however, voluntarily disclose all or part of its portfolio holdings other than in connection with the creation/redemption process, as discussed above, in advance of required filings with the SEC, provided that such information is made generally available to all shareholders and other interested parties in a manner that is consistent with the above policy for disclosure of portfolio holdings information. Such information may be made available through a publicly available website or other means that make the information available to all likely interested parties contemporaneously.

The Trust's Chief Compliance Officer or his delegate may authorize disclosure of portfolio holdings information pursuant to the above policy and procedures, subject to restrictions on selective disclosure imposed by applicable law.

The Board reviews the policy and procedures for disclosure of portfolio holdings information at least annually.

Construction and Maintenance of the Underlying Index

A description of the Underlying Index is provided below.

JPX-Nikkei 400 Net Total Return USD Hedged Index

Number of Components: approximately 399

Index Description. The JPX-Nikkei 400 Net Total Return USD Hedged Index provides exposure to broad-based Japanese equities with the currency risk of the securities included in the Underlying Index hedged to the U.S. dollar on a monthly basis.

Calculation Methodology. The daily return of the Underlying Index is calculated by the combination of the following two returns: (1) the return of the JPX-Nikkei 400 Net Total Return Index (the “Target Index”) in foreign currency, which is the return accruing from an unhedged Target Index investment to an investor whose home currency is not the Japanese yen; and (2) the return from the hedge, calculated by a linear interpolation of spot and forward prices. The hedge ratio is 100%.

Investment Restrictions

The Fund has adopted its investment objective as a non-fundamental investment policy. Therefore, the Fund may change its investment objective and its Underlying Index without shareholder approval.The Board has adopted as fundamental policies the following numbered investment restrictions, which cannot be changed without the approval of the holders of a majority of the Fund’s outstanding voting securities. A vote of a majority of the outstanding voting securities of the Fund is defined in the Investment Company Act as the lesser of (i) 67% or more of the voting securities present at a shareholder meeting, if the holders of more than 50% of the outstanding voting securities of the Fund are present or represented by proxy, or (ii) more than 50% of the outstanding voting securities of the Fund.

The Fund may not:

1.	Concentrate its investments in a particular industry, as that term is used in the Investment Company Act, except that the Fund will concentrate to approximately the same extent that its Underlying Index concentrates in the securities of a particular industry or group of industries.
2.	Borrow money, except as permitted under the Investment Company Act.
3.	Issue senior securities to the extent such issuance would violate the Investment Company Act.
4.	Purchase or hold real estate, except the Fund may purchase and hold securities or other instruments that are secured by, or linked to, real estate or interests therein, securities of real estate investment trusts, mortgage-related securities and securities of issuers engaged in the real estate business, and the Fund may purchase and hold real estate as a result of the ownership of securities or other instruments.
5.	Underwrite securities issued by others, except to the extent that the sale of portfolio securities by the Fund may be deemed to be an underwriting or as otherwise permitted by applicable law.

6.	Purchase or sell commodities or commodity contracts, except as permitted by the Investment Company Act.
7.	Make loans to the extent prohibited by the Investment Company Act.

Notations Regarding the Fund's Fundamental Investment Restrictions

The following notations are not considered to be part of the Fund's fundamental investment restrictions and are subject to change without shareholder approval.

With respect to the fundamental policy relating to concentration set forth in (1) above, the Investment Company Act does not define what constitutes “concentration” in an industry. The SEC staff has taken the position that investment of 25% or more of a fund’s total assets in one or more issuers conducting their principal activities in the same industry or group of industries constitutes concentration. It is possible that interpretations of concentration could change in the future. The policy in (1) above will be interpreted to refer to concentration as that term may be interpreted from time to time. The policy also will be interpreted to permit investment without limit in the following: securities of the U.S. government and its agencies or instrumentalities; securities of state, territory, possession or municipal governments and their authorities, agencies, instrumentalities or political subdivisions; and repurchase agreements collateralized by any such obligations. Accordingly, issuers of the foregoing securities will not be considered to be members of any industry. There also will be no limit on investment in issuers domiciled in a single jurisdiction or country. Finance companies will be considered to be in the industries of their parents if their activities are primarily related to financing the activities of the parents. Each foreign government will be considered to be a member of a separate industry. With respect to the Fund's industry classifications, the Fund currently utilizes any one or more of the industry sub-classifications used by one or more widely recognized market indexes or rating group indexes, and/or as defined by Fund management. The policy also will be interpreted to give broad authority to the Fund as to how to classify issuers within or among industries.

With respect to the fundamental policy relating to borrowing money set forth in (2) above, the Investment Company Act permits the Fund to borrow money in amounts of up to one-third of the Fund’s total assets from banks for any purpose, and to borrow up to 5% of the Fund’s total assets from banks or other lenders for temporary purposes. (The Fund’s total assets include the amounts being borrowed.) To limit the risks attendant to borrowing, the Investment Company Act requires the Fund to maintain at all times an “asset coverage” of at least 300% of the amount of its borrowings. Asset coverage means the ratio that the value of the Fund's total assets (including amounts borrowed), minus liabilities other than borrowings, bears to the aggregate amount of all borrowings. Borrowing money to increase portfolio holdings is known as “leveraging.” Certain trading practices and investments, such as reverse repurchase agreements, may be considered to be borrowings or involve leverage and thus are subject to the Investment Company Act restrictions. In accordance with SEC guidance and staff interpretations, when the Fund engages in such transactions, the Fund instead of maintaining asset coverage of at least 300%, may segregate or earmark liquid assets, or enter into an offsetting position, in an amount at least equal to the Fund’s exposure, on a mark-to-market basis, to the transaction (as calculated pursuant to requirements of the SEC). The policy in (2) above will be interpreted to permit the Fund to engage in trading practices and investments that may be considered to be borrowing or to involve leverage to the extent permitted by the Investment Company Act and to permit the Fund to segregate or earmark liquid assets or enter into offsetting positions in accordance with the Investment Company Act. Short-term credits necessary for the settlement of securities transactions and arrangements with respect to securities lending will not be considered to be borrowings under the policy. Practices and investments that may involve leverage but are not considered to be borrowings are not subject to the policy.

With respect to the fundamental policy relating to underwriting set forth in (5) above, the Investment Company Act does not prohibit the Fund from engaging in the underwriting business or from underwriting the securities of other issuers; in fact, in the case of diversified funds, the Investment Company Act permits the Fund to have underwriting commitments of up to 25% of its assets under certain circumstances. Those circumstances currently are that the amount of the Fund's underwriting commitments, when added to the value of the Fund’s investments in issuers where the Fund owns more than 10% of the outstanding voting securities of those issuers, cannot exceed the 25% cap. A fund engaging in transactions involving the acquisition or disposition of portfolio securities may be considered to be an underwriter under the 1933 Act. Although it is not believed that the application of the 1933 Act provisions described above would cause the Fund to be engaged in the business of underwriting, the policy in (5) above will be interpreted not to prevent the Fund from engaging in transactions involving the acquisition or disposition of portfolio securities, regardless of whether the Fund may be considered to be an underwriter under the 1933 Act or is otherwise engaged in the underwriting business to the extent permitted by applicable law.

With respect to the fundamental policy relating to lending set forth in (7) above, the Investment Company Act does not prohibit the Fund from making loans (including lending its securities); however, SEC staff interpretations currently prohibit funds from lending more than one-third of their total assets (including lending its securities), except through the purchase of debt obligations or the use of repurchase agreements. In addition, collateral arrangements with respect to options, forward currency and futures transactions and other derivative instruments (as applicable), as well as delays in the settlement of securities transactions, will not be considered loans.

Under its non-fundamental investment restrictions, which may be changed by the Board without shareholder approval, the Fund may not:

Purchase securities of other investment companies, except to the extent permitted by the Investment Company Act. As a matter of policy, however, the Fund will not purchase shares of any registered open-end investment company or registered unit investment trust, in reliance on Section 12(d)(1)(F) or (G) (the “fund of funds” provisions) of the Investment Company Act, at any time the Fund has knowledge that its shares are purchased by another investment company investor in reliance on the provisions of subparagraph (G) of Section 12(d)(1); provided that such policy will only be in effect if the Fund ceases to invest its assets in reliance on Section 12(d)(1)(G) in the iShares JPX-Nikkei 400 ETF.

Make short sales of securities or maintain a short position, except to the extent permitted by the Fund's Prospectus and SAI, as amended from time to time, and applicable law.

Unless otherwise indicated, all limitations under the Fund's fundamental or non-fundamental investment restrictions apply only at the time that a transaction is undertaken. Any change in the percentage of the Fund's assets invested in certain securities or other instruments resulting from market fluctuations or other changes in the Fund’s total assets will not require the Fund to dispose of an investment until BFA determines that it is practicable to sell or close out the investment without undue market or tax consequences.

The Fund has adopted a non-fundamental investment policy in accordance with Rule 35d-1 under the Investment Company Act to invest, under normal circumstances, at least 80% of the value of its net assets, plus the amount of any borrowings for investment purposes, in the component securities (including indirect investments through the Underlying Fund) and other instruments of its Underlying Index or in depositary receipts representing component securities in the Underlying Index. The Fund also has adopted a policy to provide its shareholders with at least 60 days’ prior written notice of any change in such policy. If, subsequent to an investment, the 80% requirement is no longer met, the Fund’s future investments will be made in a manner that will bring the Fund into compliance with this policy.

The Fund has adopted a non-fundamental limitation such that, under normal market conditions, any borrowings by the Fund will not exceed 10% of the Fund's net assets.

Although the SEC has granted an exemptive order to the Trust permitting registered investment companies and unit investment trusts that enter into a participation agreement with the Trust (“Investing Funds”) to invest in iShares Funds beyond the limits set forth in Section 12(d)(1) of the 1940 Act subject to certain terms and conditions, the exemptive order is not applicable to the Fund. Accordingly, Investing Funds must adhere to the limits set forth in Section 12(d)(1) of the 1940 Act when investing in the Fund.

Continuous Offering

The method by which Creation Units are created and traded may raise certain issues under applicable securities laws. Because new Creation Units are issued and sold by the Fund on an ongoing basis, at any point a “distribution,” as such term is used in the 1933 Act, may occur. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject them to the prospectus delivery requirement and liability provisions of the 1933 Act.

facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case and the examples mentioned above should not be considered a complete description of all the activities that could lead to a categorization as an underwriter.

Broker-dealer firms should also note that dealers who are not “underwriters” but are effecting transactions in shares, whether or not participating in the distribution of shares, generally are required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(a)(3) of the 1933 Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. Firms that incur a prospectus delivery obligation with respect to shares of the Fund are reminded that, pursuant to Rule 153 under the 1933 Act, a prospectus delivery obligation under Section 5(b)(2) of the 1933 Act owed to an exchange member in connection with a sale on the Listing Exchange generally is satisfied by the fact that the prospectus is available at the Listing Exchange upon request. The prospectus delivery mechanism provided in Rule 153 is available only with respect to transactions on an exchange.

Management

Trustees and Officers. The Board has responsibility for the overall management and operations of the Fund, including general supervision of the duties performed by BFA and other service providers. Each Trustee serves until he or she resigns, is removed, dies, retires or becomes incapacitated. Each officer shall hold office until his or her successor is elected and qualifies or until his or her death, resignation or removal. Trustees who are not “interested persons” (as defined in the 1940 Act) of the Trust are referred to as independent trustees (“Independent Trustees”).

The Board has concluded that, based on each Trustee’s experience, qualifications, attributes or skills on an individual basis and in combination with those of the other Trustees, each Trustee should serve as a Trustee of the Board. Among the attributes common to all Trustees are their ability to review critically, evaluate, question and discuss information provided to them, to interact effectively with the Fund's investment adviser, other service providers, counsel and the independent registered public accounting firm, and to exercise effective business judgment in the performance of their duties as Trustees. A Trustee’s ability to perform his or her duties effectively may have been attained through the Trustee’s educational background or professional training; business, consulting, public service or academic positions; experience from service as a Board member of the Fund and the other funds in the Trust (and any predecessor funds), other investment funds, public companies, or non-profit entities or other organizations; and/or other life experiences.

Board – Leadership Structure and Oversight Responsibilities

Overall responsibility for oversight of the Fund rests with the Board. The Board has engaged BFA to manage the Fund on a day-to-day basis. The Board is responsible for overseeing BFA and other service providers in the operations of the Fund in accordance with the provisions of the 1940 Act, applicable provisions of state and other laws and the Trust’s charter. The Board is currently composed of ten members, eight of whom are Independent Trustees. The Board currently conducts regular in person meetings four times a year. In addition, the Board frequently holds special in person or telephonic meetings or informal conference calls to discuss specific matters that may arise or require action between regular meetings. The Independent Trustees meet regularly outside the presence of management, in executive session or with other service providers to the Trust.

The Board has appointed an Independent Trustee to serve in the role of Board Chair. The Board Chair’s role is to preside at all meetings of the Board and to act as a liaison with service providers, officers, attorneys, and other Trustees generally between meetings. The Board Chair may also perform such other functions as may be delegated by the Board from time to time. The Board has established seven standing Committees: a Nominating and Governance Committee, an Audit Committee, a 15(c) Committee, a Securities Lending Committee, a Risk Committee, an Equity Plus Committee and a Fixed Income Plus Committee to assist the Board in the oversight and direction of the business and affairs of the Fund, and from time to time the Board may establish ad hoc committees or informal working groups to review and address the policies and practices of the Fund with respect to certain specified matters. The Chair of each standing Committee is an Independent Trustee. The role of the Chair of each Committee is to preside at all meetings of the Committee and to act as a liaison with service providers, officers, attorneys and other Trustees between meetings. Each standing Committee meets regularly to conduct the oversight functions delegated to the Committee by the Board and reports its finding to the Board. The Board and each standing Committee conduct annual assessments of their oversight function and structure. The Board has determined that the Board’s leadership structure is appropriate because it allows the Board to exercise independent judgment over management and it allocates areas of responsibility among committees of Independent Trustees and the full Board to enhance effective oversight.

Day-to-day risk management with respect to the Fund is the responsibility of BFA or other service providers (depending on the nature of the risk), subject to the supervision of BFA. The Fund is subject to a number of risks, including investment, compliance, operational, reputational, counterparty and valuation risks, among others. While there are a number of risk management functions performed by BFA and other service providers, as applicable, it is not possible to identify and eliminate all of the risks applicable to the Fund. The Trustees have an oversight role in this area, satisfying themselves that risk management processes and controls are in place and operating effectively. Risk oversight forms part of the Board’s general oversight of the Fund and is addressed as part of various Board and committee activities. In some cases, risk management issues are specifically addressed in presentations and discussions. For example, BFA has an independent dedicated Risk and Quantitative Analysis Group (“RQA”) that assists BFA in managing fiduciary and corporate risks, including investment, operational, counterparty credit and enterprise risk. Representatives of RQA meet with the Board to discuss their analysis and methodologies, as well as specific risk topics such as operational and counterparty risks relating to the Fund. The Board, directly or through a committee, also reviews reports from, among others, management and the independent registered public accounting firm for the Trust, as appropriate, regarding risks faced by the Fund and management’s risk functions. The Board has appointed a Chief Compliance Officer who oversees the implementation and testing of the Trust's compliance program, including assessments by independent third parties, and reports to the Board regarding compliance matters for the Trust and its principal service providers. In testing and maintaining the compliance program, the Chief Compliance Officer (and his or her delegates) assesses key compliance risks affecting the Fund, and addresses them in periodic reports to the Board. In addition, the Audit Committee meets with both the Fund's independent registered public accounting firm and BFA’s internal audit group to review risk controls in place that support the Fund as well as test results. Board oversight of risk is also performed as needed between meetings through communications between BFA and the Board. The Independent Trustees have engaged independent legal counsel to assist them in performing their oversight responsibilities. From time to time, the Board may modify the manner in which it conducts risk oversight. The Board’s oversight role does not make it a guarantor of the Fund's investment performance or other activities.

Potential Conflicts of Interest. The PNC Financial Services Group, Inc. (“PNC”) has a significant economic interest in BlackRock, Inc., the parent of BFA, the Fund's investment adviser. BlackRock, Inc. and PNC are considered to be affiliated persons of one another under the 1940 Act. Certain activities of BFA, BlackRock, Inc. and their affiliates (collectively, “BlackRock”) and PNC and its affiliates (collectively, “PNC” and together with BlackRock, “Affiliates”), with respect to the Fund and/or other accounts managed by BlackRock or PNC, may give rise to actual or perceived conflicts of interest such as those described below.

BlackRock is one of the world's largest asset management firms. PNC is a diversified financial services organization spanning the retail, business and corporate markets. BlackRock, PNC and their respective affiliates (including, for these purposes, their directors, partners, trustees, managing members, officers and employees), including the entities and personnel who may be involved in the investment activities and business operations of the Fund, are engaged worldwide in businesses, including managing equities, fixed-income securities, cash and alternative investments, and banking and other financial services, and have interests other than that of managing the Fund. These are considerations of which investors in the Fund should be aware, and which may cause conflicts of interest that could disadvantage the Fund and its shareholders. These businesses and interests include potential multiple advisory, transactional, financial and other relationships with, or interests in, companies and interests in securities or other instruments that may be purchased or sold by the Fund.

BlackRock and the other Affiliates have proprietary interests in, and may manage or advise with respect to, accounts or funds (including separate accounts and other funds and collective investment vehicles) that have investment objectives similar to those of the Fund and/or that engage in transactions in the same types of securities, currencies and instruments as the Fund. One or more Affiliates are also major participants in the global currency, equities, swap and fixed-income markets, in each case, for the accounts of customers and, in some cases, on a proprietary basis. As such, one or more Affiliates are or may be actively engaged in transactions in the same securities, currencies, and instruments in which the Fund invests. Such activities could affect the prices and availability of the securities, currencies, and instruments in which the Fund invests, which could have an adverse impact on the Fund's performance. Such transactions, particularly in respect of most proprietary accounts or client accounts, will be executed independently of the Fund's transactions and thus at prices or rates that may be more or less favorable than those obtained by the Fund.

When BlackRock and the other Affiliates seek to purchase or sell the same assets for their managed accounts, including the Fund, the assets actually purchased or sold may be allocated among the accounts on a basis determined in their good faith discretion to be equitable. In some cases, this system may adversely affect the size or price of the assets purchased or sold for the Fund. In addition, transactions in investments by one or more other accounts managed by BlackRock or the other Affiliates may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund, particularly, but not limited to, with respect to small-capitalization, emerging market or less liquid strategies. This may occur when investment decisions regarding the Fund are based on research or other information that is also used to support decisions for other accounts. When BlackRock or the other Affiliates implement a portfolio decision or strategy on behalf of another account ahead of, or contemporaneously with, similar decisions or strategies for the Fund, market impact, liquidity constraints, or other factors could result in the Fund receiving less favorable trading results and the costs of implementing such decisions or strategies could be increased or the Fund could otherwise be disadvantaged. BlackRock or the other Affiliates may, in certain cases, elect to implement internal policies and procedures designed to limit such consequences, which may cause the Fund to be unable to engage in certain activities, including purchasing or disposing of securities, when it might otherwise be desirable for it to do so.

Conflicts may also arise because portfolio decisions regarding the Fund may benefit other accounts managed by BlackRock or the other Affiliates. For example, the sale of a long position or establishment of a short position by the Fund may impair the price of the same security sold short by (and therefore benefit) one or more Affiliates or their other accounts or funds, and the purchase of a security or covering of a short position in a security by the Fund may increase the price of the same security held by (and therefore benefit) one or more Affiliates or their other accounts or funds.

In certain circumstances, BlackRock, on behalf of the Fund, may seek to buy from or sell securities to another fund or account advised by BlackRock or an Affiliate. BlackRock may (but is not required to) effect purchases and sales between BlackRock clients or clients of Affiliates (“cross trades”), including the Fund, if BlackRock believes such transactions are appropriate based on each party's investment objectives and guidelines, subject to applicable law and regulation. There may be potential conflicts of interest or regulatory issues relating to these transactions which could limit BlackRock’s decision to engage in these transactions for the Fund. BlackRock may have a potentially conflicting division of loyalties and responsibilities to the parties in such transactions. On any occasion when the Fund participates in a cross trade, BlackRock will comply with procedures adopted under applicable rules and SEC guidance.

BlackRock and the other Affiliates and their clients may pursue or enforce rights with respect to an issuer in which the Fund has invested, and those activities may have an adverse effect on the Fund. As a result, prices, availability, liquidity and terms of the Fund's investments may be negatively impacted by the activities of BlackRock or the other Affiliates or their clients, and transactions for the Fund may be impaired or effected at prices or terms that may be less favorable than would otherwise have been the case.

The results of the Fund’s investment activities may differ significantly from the results achieved by BlackRock and the other Affiliates for their proprietary accounts or other accounts (including investment companies or collective investment vehicles) managed or advised by them. It is possible that one or more Affiliate-managed accounts and such other accounts will achieve investment results that are substantially more or less favorable than the results achieved by the Fund. Moreover, it is possible that the Fund will sustain losses during periods in which one or more Affiliates or Affiliate-managed accounts achieve significant profits on their trading for proprietary or other accounts. The opposite result is also possible.

From time to time, the Fund may be restricted from purchasing or selling securities, or from engaging in other investment activities because of regulatory, legal or contractual requirements applicable to BlackRock or one or more Affiliates or other accounts managed or advised by BlackRock or the other Affiliates for clients worldwide, and/or the internal policies of BlackRock and the other Affiliates designed to comply with such requirements. As a result, there may be periods, for example, when BlackRock and/or one or more Affiliates will not initiate or recommend certain types of transactions in certain securities or instruments with respect to which BlackRock and/or one or more Affiliates are performing services or when position limits have been reached. For example, the investment activities of one or more Affiliates for their proprietary accounts and accounts under their management may limit the investment opportunities for the Fund in certain emerging and other markets in which limitations are imposed upon the amount of investment, in the aggregate or in individual issuers, by affiliated foreign investors.

transactions on behalf of the Fund in accordance with such analysis and models. In addition, neither BlackRock nor any of the other Affiliates will have any obligation to make available any information regarding their proprietary activities or strategies, or the activities or strategies used for other accounts managed by them, for the benefit of the management of the Fund and it is not anticipated that BlackRock will have access to such information for the purpose of managing the Fund. The proprietary activities or portfolio strategies of BlackRock and the other Affiliates, or the activities or strategies used for accounts managed by them or other customer accounts could conflict with the transactions and strategies employed by BlackRock in managing the Fund.

The Fund may be included in investment models developed by BlackRock and the other Affiliates for use by clients and financial advisors. The price, availability and liquidity of the Fund may be impacted by purchases and redemptions of the Fund by model-driven investment portfolios.

In addition, certain principals and certain employees of BlackRock are also principals or employees of Affiliates. As a result, these principals and employees may have obligations to such other entities or their clients and such obligations to other entities or clients may be a consideration of which investors in the Fund should be aware.

BlackRock may enter into transactions and invest in securities, instruments and currencies on behalf of the Fund in which clients of BlackRock or the other Affiliates, or, to the extent permitted by the SEC and applicable law, BlackRock or another Affiliate, serves as the counterparty, principal or issuer. In such cases, such party's interests in the transaction will be adverse to the interests of the Fund, and such party may have no incentive to assure that the Fund obtains the best possible prices or terms in connection with the transactions. In addition, the purchase, holding and sale of such investments by the Fund may enhance the profitability of BlackRock or the other Affiliates. One or more Affiliates may also create, write or issue derivatives for their clients, the underlying securities, currencies or instruments of which may be those in which the Fund invests or which may be based on the performance of the Fund. The Fund may, subject to applicable law, purchase investments that are the subject of an underwriting or other distribution by one or more Affiliates and may also enter into transactions with other clients of an Affiliate where such other clients have interests adverse to those of the Fund.

At times, these activities may cause departments of BlackRock or the other Affiliates to give advice to clients that may cause these clients to take actions adverse to the interests of the Fund. To the extent affiliated transactions are permitted, the Fund will deal with BlackRock and the other Affiliates (except with respect to BFA or affiliated sub-advisers of the Fund, as applicable) on an arms-length basis.

To the extent authorized by applicable law, one or more Affiliates may act as broker, dealer, agent, lender or adviser or in other commercial capacities for the Fund. It is anticipated that the commissions, markups, markdowns, financial advisory fees, underwriting and placement fees, sales fees, financing and commitment fees, brokerage fees, other fees, compensation or profits, rates, terms and conditions charged by an Affiliate will be in its view commercially reasonable, although each Affiliate, including its sales personnel, will have an interest in obtaining fees and other amounts that are favorable to the Affiliate and such sales personnel, which may have an adverse effect on the Fund.

Subject to applicable law, the Affiliates (and their personnel and other distributors) will be entitled to retain fees and other amounts that they receive in connection with their service to the Fund as broker, dealer, agent, lender, adviser or in other commercial capacities. No accounting to the Fund or its shareholders will be required, and no fees or other compensation payable by the Fund or its shareholders will be reduced by reason of receipt by an Affiliate of any such fees or other amounts.

When an Affiliate acts as broker, dealer, agent, adviser or in other commercial capacities in relation to the Fund, the Affiliate may take commercial steps in its own interests, which may have an adverse effect on the Fund. The Fund will be required to establish business relationships with its counterparties based on the Fund's own credit standing. Neither BlackRock nor any of the Affiliates will have any obligation to allow their credit to be used in connection with the Fund's establishment of its business relationships, nor is it expected that the Fund's counterparties will rely on the credit of BlackRock or any of the other Affiliates in evaluating the Fund's creditworthiness.

Lending on behalf of the Fund is done by BTC pursuant to SEC exemptive relief, enabling BTC to act as securities lending agent to, and receive a share of securities lending revenues from, the Fund. An Affiliate will also receive compensation for managing the reinvestment of the cash collateral from securities lending. There are potential conflicts of interest in managing a securities lending program, including but not limited to: (i) BTC as securities lending agent may have an incentive to increase or decrease the amount of securities on loan or to lend particular securities in order to generate additional risk-adjusted revenue for BTC and its affiliates; and (ii) BTC as securities lending agent may have an incentive to allocate loans to

clients that would provide more revenue to BlackRock. As described further below, BlackRock seeks to mitigate this conflict by providing its securities lending clients with equal lending opportunities over time in order to approximate pro-rata allocation.

As part of its securities lending program, BlackRock indemnifies certain clients or funds against a shortfall in collateral in the event of borrower default. BlackRock’s RQA calculates, on a regular basis, BlackRock’s potential dollar exposure to the risk of collateral shortfall upon counterparty default (“shortfall risk”) under the securities lending program for both indemnified and non-indemnified clients. On a periodic basis, RQA also determines the maximum amount of potential indemnified shortfall risk arising from securities lending activities (“indemnification exposure limit”) and the maximum amount of counterparty-specific credit exposure (“credit limits”) BlackRock is willing to assume as well as the program’s operational complexity. RQA oversees the risk model that calculates projected shortfall values using loan-level factors such as loan and collateral type and market value as well as specific borrower counterparty credit characteristics. When necessary, RQA may further adjust other securities lending program attributes by restricting eligible collateral or reducing counterparty credit limits. As a result, the management of the indemnification exposure limit may affect the amount of securities lending activity BlackRock may conduct at any given point in time and impact indemnified and non-indemnified clients by reducing the volume of lending opportunities for certain loans (including by asset type, collateral type and/or revenue profile).

BlackRock uses a predetermined systematic process in order to approximate pro-rata allocation over time. In order to allocate a loan to a portfolio: (i) BlackRock as a whole must have sufficient lending capacity pursuant to the various program limits (i.e., indemnification exposure limit and counterparty credit limits); (ii) the lending portfolio must hold the asset at the time a loan opportunity arrives; and (iii) the lending portfolio must also have enough inventory, either on its own or when aggregated with other portfolios into one single market delivery, to satisfy the loan request. In doing so, BlackRock seeks to provide equal lending opportunities for all portfolios, independent of whether BlackRock indemnifies the portfolio. Equal opportunities for lending portfolios does not guarantee equal outcomes. Specifically, short and long-term outcomes for individual clients may vary due to asset mix, asset/liability spreads on different securities, and the overall limits imposed by the firm.

Purchases and sales of securities and other assets for the Fund may be bunched or aggregated with orders for other BlackRock client and fund accounts, including with accounts that pay different transaction costs due to the fact that they have different research payment arrangements. BlackRock, however, is not required to bunch or aggregate orders if portfolio management decisions for different accounts or funds are made separately, or if it determines that bunching or aggregating is not practicable or required, is not in the best interest of the Fund, or in cases involving client direction.

Prevailing trading activity frequently may make impossible the receipt of the same price or execution on the entire volume of securities purchased or sold. When this occurs, the various prices may be averaged, and the Fund will be charged or credited with the average price. Thus, the effect of the aggregation may operate on some occasions to the disadvantage of the Fund. In addition, under certain circumstances, the Fund will not be charged the same commission or commission equivalent rates in connection with a bunched or aggregated order.

BlackRock may select brokers (including, without limitation, Affiliates, to the extent permitted by applicable law) that furnish BlackRock, the Fund, other BlackRock client accounts or other Affiliates or personnel, directly or through correspondent relationships, with research or other appropriate services which provide, in BlackRock's view, appropriate assistance to BlackRock in the investment decision-making process (including with respect to futures, fixed-price offerings and OTC transactions). Such research or other services may include, to the extent permitted by law, research reports on companies, industries and securities; economic and financial data; financial publications; proxy analysis; trade industry seminars; computer data bases; research-oriented software and other services and products. Research or other services obtained in this manner may be used in servicing other BlackRock client accounts, including in connection with BlackRock client accounts other than those that pay commissions to the broker relating to the research or other service arrangements. Such products and services may disproportionately benefit other BlackRock client accounts relative to the Fund based on the amount of brokerage commissions paid by the Fund and such other BlackRock client accounts. For example, research or other services that are paid for through one client's commissions may not be used in managing that client's account. In addition, other BlackRock client accounts may receive the benefit, including disproportionate benefits, of economies of scale or price discounts in connection with products and services that may be provided to the Fund and to such other BlackRock client accounts. To the extent that BlackRock uses soft dollars, it will not have to pay for those products and services itself.

BlackRock does not currently enter into arrangements to use the Fund's assets for, or participate in, soft dollars, although BlackRock may receive research that is bundled with the trade execution, clearing, and/or settlement services provided by a particular broker-dealer. To the extent that BlackRock receives research on this basis, many of the same conflicts related to traditional soft dollars may exist. For example, the research effectively will be paid by client commissions that also will be used to pay for the execution, clearing, and settlement services provided by the broker-dealer and will not be paid by BlackRock.

BlackRock may endeavor to execute trades through brokers who, pursuant to such arrangements, provide research or other services in order to ensure the continued receipt of research or other services BlackRock believes are useful in its investment decision-making process. BlackRock may from time to time choose not to engage in the above described arrangements to varying degrees. BlackRock may also enter into commission sharing arrangements under which BlackRock may execute transactions through a broker-dealer, including, where permitted, an Affiliate, and request that the broker-dealer allocate a portion of the commissions or commission credits to another firm that provides research to BlackRock. To the extent that BlackRock engages in commission sharing arrangements, many of the same conflicts related to traditional soft dollars may exist.

BlackRock may utilize certain electronic crossing networks (“ECNs”) (including, without limitation, ECNs in which BlackRock or the other Affiliates have an investment or other interest, to the extent permitted by applicable law) in executing client securities transactions for certain types of securities. These ECNs may charge fees for their services, including access fees and transaction fees. The transaction fees, which are similar to commissions or markups/markdowns, will generally be charged to clients and, like commissions and markups/markdowns, would generally be included in the cost of the securities purchased. Access fees may be paid by BlackRock even though incurred in connection with executing transactions on behalf of clients, including the Fund. In certain circumstances, ECNs may offer volume discounts that will reduce the access fees typically paid by BlackRock. BlackRock will only utilize ECNs consistent with its obligation to seek to obtain best execution in client transactions.

BlackRock has adopted policies and procedures designed to prevent conflicts of interest from influencing proxy voting decisions that it makes on behalf of advisory clients, including the Fund, and to help ensure that such decisions are made in accordance with BlackRock's fiduciary obligations to its clients. Nevertheless, notwithstanding such proxy voting policies and procedures, actual proxy voting decisions of BlackRock may have the effect of favoring the interests of other clients or businesses of other divisions or units of BlackRock and/or the other Affiliates, provided that BlackRock believes such voting decisions to be in accordance with its fiduciary obligations. For a more detailed discussion of these policies and procedures, see the Proxy Voting Policy section of this SAI.

It is also possible that, from time to time, BlackRock or the other Affiliates may, subject to compliance with applicable law, purchase and hold shares of the Fund. Increasing the Fund’s assets may enhance liquidity, investment flexibility and diversification and may contribute to economies of scale that tend to reduce the Fund's expense ratio. BlackRock and the other Affiliates reserve the right, subject to compliance with applicable law, to sell into the market or redeem in Creation Units through an Authorized Participant at any time some or all of the shares of the Fund acquired for their own accounts. A large sale or redemption of shares of the Fund by BlackRock or the other Affiliates could significantly reduce the asset size of the Fund, which might have an adverse effect on the Fund's liquidity, investment flexibility, portfolio diversification, expense ratio or ability to comply with the listing requirements for the Fund. BlackRock seeks to consider the effect of redemptions on the Fund and other shareholders in deciding whether to redeem its shares but is not obligated to do so and may elect not to do so.

It is possible that the Fund may invest in securities of, or engage in transactions with, companies with which an Affiliate has developed or is trying to develop investment banking relationships as well as securities of entities in which BlackRock or the other Affiliates has significant debt or equity investments or other interests or in which an Affiliate makes a market. The Fund also may invest in securities of, or engage in transactions with, companies to which an Affiliate provides or may in the future provide research coverage. Such investments or transactions could cause conflicts between the interests of the Fund and the interests of BlackRock, other clients of BlackRock or the other Affiliates. In making investment decisions for the Fund, BlackRock is not permitted to obtain or use material non-public information acquired by any division, department or Affiliate of BlackRock in the course of these activities. In addition, from time to time, the activities of an Affiliate may limit the Fund's flexibility in purchases and sales of securities. When an Affiliate is engaged in an underwriting or other distribution of securities of an entity, BlackRock may be prohibited from purchasing or recommending the purchase of certain securities of

that entity for the Fund. As indicated below, BlackRock or the other Affiliates may engage in transactions with companies in which BlackRock-advised funds or other clients of BlackRock or of an Affiliate have an investment.

BlackRock and Chubb Limited (“Chubb”), a public company whose securities are held by BlackRock-advised funds and other accounts, partially funded the creation of a re-insurance company (“Re Co”) pursuant to which each has approximately a 9.9% ownership interest and each has representation on the board of directors. Certain employees and executives of BlackRock have a less than ½ of 1% ownership interest in Re Co. BlackRock manages the investment portfolio of Re Co, which is held in a wholly-owned subsidiary. Re Co participates as a reinsurer with reinsurance contracts underwritten by subsidiaries of Chubb. An independent director of certain BlackRock-advised funds also serves as an independent director of Chubb and has no interest or involvement in the Re Co transaction.

BlackRock and the other Affiliates, their personnel and other financial service providers may have interests in promoting sales of the Fund. With respect to BlackRock and the other Affiliates and their personnel, the remuneration and profitability relating to services to and sales of the Fund or other products may be greater than remuneration and profitability relating to services to and sales of certain funds or other products that might be provided or offered. BlackRock and the other Affiliates and their sales personnel may directly or indirectly receive a portion of the fees and commissions charged to the Fund or its shareholders. BlackRock and its advisory or other personnel may also benefit from increased amounts of assets under management. Fees and commissions may also be higher than for other products or services, and the remuneration and profitability to BlackRock or the other Affiliates and such personnel resulting from transactions on behalf of or management of the Fund may be greater than the remuneration and profitability resulting from other funds or products.

BlackRock and the other Affiliates and their personnel may receive greater compensation or greater profit in connection with an account for which BlackRock serves as an adviser than with an account advised by an unaffiliated investment adviser. Differentials in compensation may be related to the fact that BlackRock may pay a portion of its advisory fee to its Affiliate, or relate to compensation arrangements, including for portfolio management, brokerage transactions or account servicing. Any differential in compensation may create a financial incentive on the part of BlackRock or the other Affiliates and their personnel to recommend BlackRock over unaffiliated investment advisers or to effect transactions differently in one account over another.

Third parties, including service providers to BlackRock or the Fund, may sponsor events (including, but not limited to, marketing and promotional activities and presentations, educational training programs and conferences) for registered representatives, other professionals and individual investors. There is a potential conflict of interest as such sponsorships may defray the costs of such activities to BlackRock, and may provide an incentive to BlackRock to retain such third parties to provide services to the Fund.

BlackRock and the other Affiliates may provide valuation assistance to certain clients with respect to certain securities or other investments and the valuation recommendations made for their clients' accounts may differ from the valuations for the same securities or investments assigned by the Fund's pricing vendors, especially if such valuations are based on broker-dealer quotes or other data sources unavailable to the Fund's pricing vendors. While BlackRock will generally communicate its valuation information or determinations to the Fund's pricing vendors and/or fund accountants, there may be instances where the Fund's pricing vendors or fund accountants assign a different valuation to a security or other investment than the valuation for such security or investment determined or recommended by BlackRock.

As disclosed in more detail in the Determination of Net Asset Value section of the Fund’s Prospectus and this SAI, when market quotations are not readily available or are believed by BlackRock to be unreliable, the Fund’s investments are valued at fair value by BlackRock in accordance with procedures adopted by the Board. When determining “fair value price,” BlackRock seeks to determine the price that the Fund might reasonably expect to receive from the current sale of that asset or liability in an arm’s-length transaction. The price generally may not be determined based on what the Fund might expect to receive for selling an asset or liability at a later time or if it holds the asset or liability to maturity. While fair value determinations will be based upon all available factors that BlackRock deems relevant at the time of the determination, and may be based on analytical values determined by BlackRock using proprietary or third-party valuation models, fair value represents only a good faith approximation of the value of an asset or liability. The fair value of one or more assets or liabilities may not, in retrospect, be the price at which those assets or liabilities could have been sold during the period in which the particular fair values were used in determining the Fund’s net asset value. As a result, the Fund’s sale or redemption of its shares at net asset value, at a time when a holding or holdings are valued by BlackRock (pursuant to Board-adopted procedures) at fair value, may have the

effect of diluting or increasing the economic interest of existing shareholders and may affect the amount of revenue received by BlackRock with respect to services for which it receives an asset-based fee.

To the extent permitted by applicable law, the Fund may invest all or some of its short-term cash investments in any money market fund or similarly-managed private fund advised or managed by BlackRock. In connection with any such investments, the Fund, to the extent permitted by the 1940 Act, may pay its share of expenses of a money market fund or other similarly-managed private fund in which it invests, which may result in the Fund bearing some additional expenses.

BlackRock and the other Affiliates and their directors, officers and employees, may buy and sell securities or other investments for their own accounts and may have conflicts of interest with respect to investments made on behalf of the Fund. As a result of differing trading and investment strategies or constraints, positions may be taken by directors, officers, employees and Affiliates that are the same, different from or made at different times than positions taken for the Fund. To lessen the possibility that the Fund will be adversely affected by this personal trading, the Fund, BFA and BlackRock, Inc. have each adopted a code of ethics in compliance with Section 17(j) of the 1940 Act that restricts securities trading in the personal accounts of investment professionals and others who normally come into possession of information regarding the Fund's portfolio transactions. Each code of ethics is available by contacting BlackRock or by accessing the EDGAR Database on the SEC's Internet site at http://www.sec.gov, and copies may be obtained, after paying a duplicating fee, by e-mail at publicinfo@sec.gov or by writing the SEC's Public Reference Room, Washington, DC 20549-1520. Information about accessing documents on the SEC’s website may be obtained by calling the SEC at (800) SEC-0330.

BlackRock and the other Affiliates will not purchase securities or other property from, or sell securities or other property to, the Fund, except that the Fund may in accordance with rules or guidance adopted under the 1940 Act engage in transactions with accounts that are affiliated with the Fund as a result of common officers, directors, or investment advisers or pursuant to exemptive orders granted to the Fund and/or BlackRock by the SEC. These transactions would be effected in circumstances in which BlackRock determined that it would be appropriate for the Fund to purchase and another client of BlackRock to sell, or the Fund to sell and another client of BlackRock to purchase, the same security or instrument on the same day. From time to time, the activities of the Fund may be restricted because of regulatory requirements applicable to BlackRock or the other Affiliates and/or BlackRock's internal policies designed to comply with, limit the applicability of, or otherwise relate to such requirements. A client not advised by BlackRock would not be subject to some of those considerations. There may be periods when BlackRock may not initiate or recommend certain types of transactions, or may otherwise restrict or limit their advice in certain securities or instruments issued by or related to companies for which an Affiliate is performing investment banking, market making, advisory or other services or has proprietary positions. For example, when an Affiliate is engaged in an underwriting or other distribution of securities of, or advisory services for, a company, the Fund may be prohibited from or limited in purchasing or selling securities of that company. In addition, when BlackRock provides advisory or risk management services for a company, BlackRock may be prohibited from or limited in purchasing or selling securities of that company on behalf of the Fund, particularly where such services result in BlackRock obtaining material non-public information about the company (e.g., in connection with participation in a creditors’ committee). Similar situations could arise if personnel of BlackRock or the other Affiliates serve as directors of companies the securities of which the Fund wishes to purchase or sell. However, if permitted by applicable law, and where consistent with BlackRock’s policies and procedures (including the necessary implementation of appropriate information barriers), the Fund may purchase securities or instruments that are issued by such companies, are the subject of an underwriting, distribution or advisory assignment by an Affiliate, or are the subject of an advisory or risk management assignment by BlackRock, or where personnel of BlackRock or the other Affiliates are directors or officers of the issuer.

The investment activities of one or more Affiliates for their proprietary accounts and for client accounts may also limit the investment strategies and rights of the Fund. For example, in certain circumstances where the Fund invests in securities issued by companies that operate in certain regulated industries or in certain emerging or international markets, or is subject to corporate or regulatory ownership restrictions, or invests in certain futures or other derivative transactions, there may be limits on the aggregate amount invested by Affiliates (including BlackRock) for their proprietary accounts and for client accounts (including the Fund) that may not be exceeded without the grant of a license or other regulatory or corporate consent or, if exceeded, may cause BlackRock, the Fund or other client accounts to suffer disadvantages or business restrictions.

a result, BlackRock, on behalf of clients (including the Fund), may limit purchases, sell existing investments, or otherwise restrict, forgo or limit the exercise of rights (including transferring, outsourcing or limiting voting rights or forgoing the right to receive dividends) when BlackRock, in its sole discretion, deems it appropriate in light of potential regulatory or other restrictions on ownership or other consequences resulting from reaching investment thresholds.

In those circumstances where ownership thresholds or limitations must be observed, BlackRock seeks to allocate limited investment opportunities equitably among clients (including the Fund), taking into consideration benchmark weight and investment strategy. BlackRock has adopted certain controls designed to prevent the occurrence of a breach of any applicable ownership threshold or limits, including, for example, when ownership in certain securities nears an applicable threshold, BlackRock may remove such securities from the list of Deposit Securities to be delivered to the Fund in connection with purchases of Creation Units of such Fund and may limit purchases in such securities to the issuer's weighting in the applicable benchmark used by BlackRock to manage such Fund. If client (including Fund) holdings of an issuer exceed an applicable threshold and BlackRock is unable to obtain relief to enable the continued holding of such investments, it may be necessary to sell down these positions to meet the applicable limitations. In these cases, benchmark overweight positions will be sold prior to benchmark positions being reduced to meet applicable limitations.

In addition to the foregoing, other ownership thresholds may trigger reporting requirements to governmental and regulatory authorities, and such reports may entail the disclosure of the identity of a client or BlackRock’s intended strategy with respect to such security or asset.

BlackRock and the other Affiliates may not serve as Authorized Participants in the creation and redemption of iShares ETFs, but may serve as authorized participants of third-party ETFs.

BlackRock may enter into contractual arrangements with third-party service providers to the Fund (e.g., custodians and administrators) pursuant to which BlackRock receives fee discounts or concessions in recognition of BlackRock’s overall relationship with such service providers. To the extent that BlackRock is responsible for paying these service providers out of its management fee, the benefits of any such fee discounts or concessions may accrue, in whole or in part, to BlackRock.

BlackRock or the other Affiliates own or have an ownership interest in certain trading, portfolio management, operations and/or information systems used by Fund service providers. These systems are, or will be, used by a Fund service provider in connection with the provision of services to accounts managed by BlackRock and funds managed and sponsored by BlackRock, including the Fund, that engage the service provider (typically the custodian). The Fund’s service provider remunerates BlackRock or the other Affiliates for the use of the systems. The Fund service provider’s payments to BlackRock or the other Affiliates for the use of these systems may enhance the profitability of BlackRock and the other Affiliates. BlackRock’s or the other Affiliates’ receipt of fees from a service provider in connection with the use of systems provided by BlackRock or the other Affiliates may create an incentive for BlackRock to recommend that the Fund enter into or renew an arrangement with the service provider.

Present and future activities of BlackRock and the other Affiliates, including BFA, in addition to those described in this section, may give rise to additional conflicts of interest.

Legal Proceedings. On June 16, 2016, investors (the “Plaintiffs”) in certain iShares funds (iShares Core S&P Small-Cap ETF, iShares Russell 1000 Growth ETF, iShares Core S&P 500 ETF, iShares Russell Mid-Cap Growth ETF, iShares Russell Mid-Cap ETF, iShares Russell Mid-Cap Value ETF, iShares Select Dividend ETF, iShares Morningstar Mid-Cap ETF, iShares Morningstar Large-Cap ETF, iShares U.S. Aerospace & Defense ETF and iShares U.S. Preferred Stock ETF) filed a putative class action lawsuit against the Trust, BlackRock, Inc. and certain of its advisory affiliates, and certain directors/trustees and officers of the Trust (collectively, “Defendants”) in California State Court. The lawsuit alleges the Defendants violated federal securities laws by failing to adequately disclose in the prospectuses issued by the funds noted above the risks of using stop-loss orders in the event of a “flash crash,” such as the one that occurred on May 6, 2010. On September 18, 2017, the court issued a Statement of Decision holding that the Plaintiffs lack standing to assert their claims. On October 11, 2017, the court entered final judgment dismissing all of Plaintiffs’ claims with prejudice. Plaintiffs have appealed the court’s decision.

Investment Advisory, Administrative and Distribution Services

Investment Adviser. BFA serves as investment adviser to the Fund pursuant to an investment advisory agreement between the Trust, on behalf of the Fund, and BFA. BFA is a California corporation indirectly owned by BlackRock, Inc. and is registered as an investment adviser under the Investment Advisers Act of 1940, as amended. Under the investment advisory agreement, BFA, subject to the supervision of the Board and in conformity with the stated investment policies of the Fund, manages and administers the Trust and the investment of the Fund’s assets. BFA is responsible for placing purchase and sale orders and providing continuous supervision of the investment portfolio of the Fund.

Pursuant to the investment advisory agreement, BFA may, from time to time, in its sole discretion and to the extent permitted by applicable law, appoint one or more sub-advisers, including, without limitation, affiliates of BFA, to perform investment advisory or other services with respect to the Fund. In addition, BFA may delegate certain of its investment advisory functions under the investment advisory agreement to one or more of its affiliates to the extent permitted by applicable law. BFA may terminate any or all sub-advisers or such delegation arrangements in its sole discretion upon appropriate notice at any time to the extent permitted by applicable law.

BFA is responsible, under the investment advisory agreement, for substantially all expenses of the Fund, including the cost of transfer agency, custody, fund administration, legal, audit and other services. BFA is not responsible for, and the Fund will bear, the management fees, interest expenses, taxes, expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, distribution fees or expenses, litigation expenses and any extraordinary expenses (as determined by a majority of the Independent Trustees).

The following table sets forth the management fee at the annual rate (as a percentage of the Fund's average daily net assets) BFA received from the Fund for the fiscal year ended March 31, 2018 and the management fees (net of waivers) the Fund paid BFA for the fiscal years noted:

Management Fee for Fiscal Year Ended March 31, 2018¹		Fund Inception Date		Management Fees Paid Net of Waivers for Fiscal Year Ended March 31, 2018		Management Fees Paid Net of Waivers for Fiscal Year Ended March 31, 2017		Management Fees Paid Net of Waivers for Fiscal Year Ended March 31, 2016
0.59%		09/29/15		$0		$0		$50

BFA has contractually agreed to waive a portion of its management fees so that the Fund's total annual fund operating expenses after fee waiver is equal to the Acquired Fund Fees and Expenses attributable to the Fund's investment in the iShares JPX-Nikkei 400 ETF (“JPXN”), after taking into account any fee waivers by JPXN through July 31, 2020. The contractual waiver may be terminated prior to July 31, 2020 only upon written agreement of the Trust and BFA. For the fiscal years ended March 31, 2018, March 31, 2017 and March 31, 2016, BFA waived $15,908, $14,949 and $12,704 of management fees, respectively.

The investment advisory agreement with respect to the Fund continues in effect for two years from its effective date, and thereafter is subject to annual approval by (i) the Board, or (ii) the vote of a majority of the outstanding voting securities (as defined in the 1940 Act) of the Fund, provided that in either event such continuance also is approved by a majority of the Board members who are not interested persons (as defined in the 1940 Act) of the Fund, by a vote cast in person at a meeting called for the purpose of voting on such approval.

The investment advisory agreement with respect to the Fund is terminable without penalty, on 60 days’ notice, by the Board or by a vote of the holders of a majority of the Fund’s outstanding voting securities (as defined in the 1940 Act). The investment advisory agreement is also terminable upon 60 days’ notice by BFA and will terminate automatically in the event of its assignment (as defined in the 1940 Act).

Portfolio Managers. As of March 31, 2018, the individuals named as Portfolio Managers in the Fund's Prospectus were also primarily responsible for the day-to-day management of other iShares funds and certain other types of portfolios and/or accounts as follows:

Each of the portfolios or accounts for which the Portfolio Managers are primarily responsible for the day-to-day management seeks to track the rate of return, risk profile and other characteristics of independent third-party indexes by either replicating the same combination of securities and other financial instruments that constitute those indexes or through a representative sampling of the securities and other financial instruments that constitute those indexes based on objective criteria and data. Pursuant to BFA’s policy, investment opportunities are allocated equitably among the Fund and other portfolios and accounts. For example, under certain circumstances, an investment opportunity may be restricted due to limited supply in the market, legal constraints or other factors, in which event the investment opportunity will be allocated equitably among those portfolios and accounts, including the Fund, seeking such investment opportunity. As a consequence, from time to time the Fund may receive a smaller allocation of an investment opportunity than it would have if the Portfolio Managers and BFA and its affiliates did not manage other portfolios or accounts.

Like the Fund, the other portfolios or accounts for which the Portfolio Managers are primarily responsible for the day-to-day portfolio management generally pay an asset-based fee to BFA or its affiliates, as applicable, for its advisory services. One or more of those other portfolios or accounts, however, may pay BFA or its affiliates a performance-based fee in lieu of, or in addition to, an asset-based fee for its advisory services. A portfolio or account with a performance-based fee would pay BFA or its affiliates a portion of that portfolio’s or account’s gains, or would pay BFA or its affiliates more for its services than would otherwise be the case if BFA or any of its affiliates meets or exceeds specified performance targets. Performance-based fee arrangements could present an incentive for BFA or its affiliates to devote greater resources, and allocate more investment opportunities, to the portfolios or accounts that have those fee arrangements, relative to other portfolios or accounts, in order to earn larger fees. Although BFA and each of its affiliates have an obligation to allocate resources and opportunities equitably among portfolios and accounts and intend to do so, shareholders of the Fund should be aware that,

as with any group of portfolios and accounts managed by an investment adviser and/or its affiliates pursuant to varying fee arrangements, including performance-based fee arrangements, there is the potential for a conflict of interest, which may result in the Portfolio Managers favoring those portfolios or accounts with performance-based fee arrangements.

The tables below show, for each Portfolio Manager, the number of portfolios or accounts of the types set forth in the above tables and the aggregate of total assets in those portfolios or accounts with respect to which the investment management fees are based on the performance of those portfolios or accounts as of March 31, 2018:

The discussion below describes the Portfolio Managers' compensation as of March 31, 2018.

Portfolio Manager Compensation Overview

include a base salary, a performance-based discretionary bonus, participation in various benefits programs and one or more of the incentive compensation programs established by BlackRock, Inc.

Base compensation. Generally, portfolio managers receive base compensation based on their position with the firm.

Discretionary Incentive Compensation. Discretionary incentive compensation is a function of several components: the performance of BlackRock, Inc., the performance of the portfolio manager's group within BlackRock, Inc. and the individual's performance and contribution to the overall performance of these portfolios and BlackRock, Inc.

Distribution of Discretionary Incentive Compensation. Discretionary incentive compensation is distributed to portfolio managers in a combination of cash and BlackRock, Inc. restricted stock units which vest ratably over a number of years. The BlackRock, Inc. restricted stock units, if properly vested, will be settled in BlackRock, Inc. common stock. Typically, the cash bonus, when combined with base salary, represents more than 60% of total compensation for the portfolio managers. Paying a portion of annual bonuses in stock puts compensation earned by a portfolio manager for a given year “at risk” based on BlackRock, Inc.'s ability to sustain and improve its performance over future periods.

Long-Term Incentive Plan Awards — From time to time, long-term incentive equity awards are granted to certain key employees to aid in retention, align their interests with long-term shareholder interests and motivate performance. Equity awards are generally granted in the form of BlackRock, Inc. restricted stock units that, once vested, settle in BlackRock, Inc. common stock.

Other Compensation Benefits. In addition to base compensation and discretionary incentive compensation, portfolio managers may be eligible to receive or participate in one or more of the following:

Incentive Savings Plans — BlackRock, Inc. has created a variety of incentive savings plans in which BlackRock, Inc. employees are eligible to participate, including a 401(k) plan, the BlackRock Retirement Savings Plan (“RSP”), and the BlackRock Employee Stock Purchase Plan (“ESPP”). The employer contribution components of the RSP include a company match equal to 50% of the first 8% of eligible pay contributed to the plan capped at $5,000 per year, and a company retirement contribution equal to 3-5% of eligible compensation up to the U.S. Internal Revenue Service (the “IRS”) limit ($275,000 for 2018). The RSP offers a range of investment options, including registered investment companies and collective investment funds managed by the firm. BlackRock, Inc. contributions follow the investment direction set by participants for their own contributions or, absent participant investment direction, are invested into an index target date fund that corresponds to, or is closest to, the year in which the participant attains age 65. The ESPP allows for investment in BlackRock, Inc. common stock at a 5% discount on the fair market value of the stock on the purchase date. Annual participation in the ESPP is limited to the purchase of 1,000 shares of common stock or a dollar value of $25,000 based on its fair market value on the Purchase Date. Diane Hsiung, Jennifer Hsui, Alan Mason, Orlando Montalvo and Greg Savage are each eligible to participate in these plans.

As of March 31, 2018, the Portfolio Managers did not beneficially own shares of the Fund.

Codes of Ethics. The Trust, BFA and the Distributor have adopted codes of ethics pursuant to Rule 17j-1 under the 1940 Act. The codes of ethics permit personnel subject to the codes of ethics to invest in securities, subject to certain limitations, including securities that may be purchased or held by the Fund. The codes of ethics are on public file with, and are available from, the SEC.

Anti-Money Laundering Requirements. The Fund is subject to the USA PATRIOT Act (the “Patriot Act”). The Patriot Act is intended to prevent the use of the U.S. financial system in furtherance of money laundering, terrorism or other illicit activities. Pursuant to requirements under the Patriot Act, the Fund may request information from Authorized Participants to enable it to form a reasonable belief that it knows the true identity of its Authorized Participants. This information will be used to verify the identity of Authorized Participants or, in some cases, the status of financial professionals; it will be used only for compliance with the requirements of the Patriot Act.

The Fund reserves the right to reject purchase orders from persons who have not submitted information sufficient to allow the Fund to verify their identity. The Fund also reserves the right to redeem any amounts in the Fund from persons whose identity it is unable to verify on a timely basis. It is the Fund's policy to cooperate fully with appropriate regulators in any investigations conducted with respect to potential money laundering, terrorism or other illicit activities.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) serves as administrator, custodian and transfer agent for the Fund under the Master Services Agreement and related Service Schedule (the “Service Module”). State Street’s principal address is 1 Lincoln Street, Boston, MA 02111. Pursuant to the Service Module for Fund Administration and Accounting Services with the Trust, State Street provides necessary administrative, legal, tax and accounting and financial reporting services for the maintenance and operations of the Trust and the Fund. In addition, State Street makes available the office space, equipment, personnel and facilities required to provide such services. Pursuant to the Service Module for Custodial Services with the Trust, State Street maintains, in separate accounts, cash, securities and other assets of the Trust and the Fund, keeps all necessary accounts and records and provides other services. State Street is required, upon the order of the Trust, to deliver securities held by State Street and to make payments for securities purchased by the Trust for the Fund. State Street is authorized to appoint certain foreign custodians or foreign custody managers for Fund investments outside the U.S. Pursuant to the Service Module for Transfer Agency Services with the Trust, State Street acts as a transfer agent for the Fund’s authorized and issued shares of beneficial interest, and as dividend disbursing agent of the Trust. As compensation for these services, State Street receives certain out-of-pocket costs, transaction fees and asset-based fees which are accrued daily and paid monthly by BFA from its management fee.

The following table sets forth the administration, custodian and transfer agency expenses of the Fund paid by BFA to State Street for the fiscal years noted:

Fund Inception Date		Custody, Administration & Transfer Agency Expenses Paid During Fiscal Year Ended March 31, 2018		Custody, Administration & Transfer Agency Expenses Paid During Fiscal Year Ended March 31, 2017		Custody, Administration & Transfer Agency Expenses Paid During Fiscal Year Ended March 31, 2016
09/29/15		$3,047		$1,371		$886

Distributor. The Distributor's principal address is 1 University Square Drive, Princeton, NJ 08540. Shares are continuously offered for sale by the Fund through the Distributor or its agent only in Creation Units, as described in the Prospectus and below in the Creation and Redemption of Creation Units section of this SAI. Fund shares in amounts less than Creation Units are generally not distributed by the Distributor or its agent. The Distributor or its agent will arrange for the delivery of the Prospectus and, upon request, this SAI to persons purchasing Creation Units and will maintain records of both orders placed with it or its agents and confirmations of acceptance furnished by it or its agents. The Distributor is a broker-dealer registered under the Securities Exchange Act of 1934, as amended (the “1934 Act”), and a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). The Distributor is also licensed as a broker-dealer in all 50 U.S. states, as well as in Puerto Rico, the U.S. Virgin Islands and the District of Columbia.

The Distribution Agreement for the Fund provides that it may be terminated at any time, without the payment of any penalty, on at least 60 days' prior written notice to the other party following (i) the vote of a majority of the Independent Trustees, or (ii) the vote of a majority of the outstanding voting securities (as defined in the 1940 Act) of the Fund. The Distribution Agreement will terminate automatically in the event of its assignment (as defined in the 1940 Act).

The Distributor may also enter into agreements with securities dealers (“Soliciting Dealers”) who will solicit purchases of Creation Units of Fund shares. Such Soliciting Dealers may also be Authorized Participants (as described below), DTC participants and/or investor services organizations.

BFA or its affiliates may, from time to time and from its own resources, pay, defray or absorb costs relating to distribution, including payments out of its own resources to the Distributor, or to otherwise promote the sale of shares.

Securities Lending. To the extent that the Fund engages in securities lending, the Fund conducts its securities lending pursuant to SEC exemptive relief, and BTC acts as securities lending agent for the Fund, subject to the overall supervision of BFA, pursuant to a written agreement (the “Securities Lending Agency Agreement”).

a money market fund managed by BFA (the “collateral investment fees”); however, BTC has agreed to reduce the amount of securities lending income it receives in order to effectively limit the collateral investment fees the Fund bears to an annual rate of 0.04%. Such money market fund shares will not be subject to a sales load, redemption fee, distribution fee or service fee.

Pursuant to the Securities Lending Agency Agreement:

(i) Fund-of-funds, such as the Fund, retain 80% of securities lending income (which excludes collateral investment fees) and (ii) this amount can never be less than 70% of the sum of securities lending income plus collateral investment fees.

Under the securities lending program, the Fund is categorized into one of several specific asset classes. The determination of the Fund’s asset class category (fixed-income, domestic equity, international equity or fund-of-funds), each of which may be subject to a different fee arrangement, is based on a methodology agreed to by the Trust and BTC.

In addition, commencing the business day following the date that the aggregate securities lending income (which includes, for this purpose, collateral investment fees) earned across the Exchange-Traded Fund Complex (as defined under “Management—Trustees and Officers”) in a calendar year exceeds the aggregate securities lending income earned across the Exchange-Traded Fund Complex in calendar year 2013 (the Hurdle Date), each applicable fund-of-funds, pursuant to the securities lending agreement, will receive for the remainder of that calendar year securities lending income as follows:

(i) 85% of securities lending income (which excludes collateral investment fees) and (ii) this amount can never be less than 70% of the sum of securities lending income plus collateral investment fees.

The services provided to the Funds by BTC in the most recent fiscal year ended March 31, 2018 primarily included the following:

(1) selecting borrowers from an approved list of borrowers and executing a securities lending agreement as agent on behalf of the Funds with each such borrower;

(2) negotiating the terms of securities loans, including the amount of fees;

(3) directing the delivery of loaned securities;

(4) monitoring the daily value of the loaned securities and directing the payment of additional collateral or the return of excess collateral, as necessary;

(5) investing cash collateral received in connection with any loaned securities;

(6) monitoring distributions on loaned securities (for example, interest and dividend activity);

(7) in the event of default by a borrower with respect to any securities loan, using the collateral or the proceeds of the liquidation of collateral to purchase replacement securities of the same issue, type, class and series as that of the loaned securities; and

(8) terminating securities loans and arranging for the return of loaned securities to the Funds at loan termination.

The following tables show the dollar amounts of income and fees/compensation related to the securities lending activities of the Fund during its most recent fiscal year ended March 31, 2018.

Payments by BFA and its Affiliates. BFA and/or its affiliates (“BFA Entities”) may pay certain broker-dealers, registered investment advisers, banks and other financial intermediaries (“Intermediaries”) for certain activities related to the Fund, other iShares funds or exchange-traded products in general. BFA Entities make these payments from their own assets and not from the assets of the Fund. Although a portion of BFA Entities’ revenue comes directly or indirectly in part from fees paid by the Fund, other iShares funds or exchange-traded products, these payments do not increase the price paid by investors for the purchase of shares of, or the cost of owning, the Fund, other iShares funds or exchange-traded products. BFA Entities make payments for Intermediaries’ participation in activities that are designed to make registered representatives, other professionals and individual investors more knowledgeable about exchange-traded products, including the Fund and other iShares funds, or for other activities, such as participation in marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems (“Education Costs”). BFA Entities also make payments to Intermediaries for certain printing, publishing and mailing costs or materials relating to the Fund, other iShares funds or exchange-traded products (“Publishing Costs”). In addition, BFA Entities make payments to Intermediaries that make shares of the Fund, other iShares funds or exchange-traded products available to their clients, develop new products that feature iShares or otherwise promote the Fund, other iShares funds and exchange-traded products. BFA Entities may also reimburse expenses or make payments from their own assets to Intermediaries or other persons in consideration of services or other activities that the BFA Entities believe may benefit the iShares business or facilitate investment in the Fund, other iShares funds or exchange-traded products. Payments of the type described above are sometimes referred to as revenue-sharing payments.

Payments to an Intermediary may be significant to the Intermediary, and amounts that Intermediaries pay to your salesperson or other investment professional may also be significant for your salesperson or other investment professional. Because an Intermediary may make decisions about which investment options it will recommend or make available to its clients or what services to provide for various products based on payments it receives or is eligible to receive, such payments may create conflicts of interest between the Intermediary and its clients and these financial incentives may cause the Intermediary to recommend the Fund, other iShares funds or exchange-traded products over other investments. The same conflicts of interest and financial incentives exist with respect to your salesperson or other investment professional if he or she receives similar payments from his or her Intermediary firm.

In addition to the payments described above, BFA Entities have developed proprietary tools, calculators and related interactive or digital content that is made available through the www.BlackRock.com website at no additional cost to Intermediaries. BlackRock may configure these tools and calculators and localizes the content for Intermediaries as part of its customary digital marketing support and promotion of the Fund, other iShares funds, exchange-traded products and BlackRock mutual funds.

As of March 1, 2013, BFA Entities have contractual arrangements to make payments (in addition to payments for Education Costs or Publishing Costs) to one Intermediary, Fidelity Brokerage Services LLC (“FBS”). Effective June 4, 2016, this relationship was expanded to include National Financial Services, LLC (“NFS”), an affiliate of FBS. Pursuant to this special, long-term and significant arrangement (the “Marketing Program”), FBS, NFS and certain of their affiliates (collectively “Fidelity”) have agreed, among other things, to actively promote iShares funds to customers, investment professionals and other intermediaries and in advertising campaigns as the preferred exchange-traded product, to offer certain iShares funds in certain Fidelity platforms and investment programs, in some cases at a waived or reduced commission rate or ticket charge, and to provide marketing data to BFA Entities. BFA Entities have agreed to facilitate the Marketing Program by, among other things, making certain payments to FBS and NFS for marketing and implementing certain brokerage and investment programs. Upon termination of the arrangement, the BFA Entities will make additional payments to FBS and/or NFS based upon a number of criteria, including the overall success of the Marketing Program and the level of services provided by FBS and NFS during the wind-down period.

In addition, BFA Entities may enter into other contractual arrangements with Intermediaries and certain other third parties that the BFA Entities believe may benefit the iShares business or facilitate investment in iShares funds. Such agreements may include payments by BFA Entities to such Intermediaries and third parties for data collection and provision, technology support, platform enhancement, or co-marketing and cross-promotional efforts. Payments made pursuant to such arrangements may vary in any year and may be different for different Intermediaries and third parties. In certain cases, the payments described in the preceding sentence may be subject to certain minimum payment levels. Such payments will not be asset- or revenue-based. As of the date of this SAI, the Intermediaries and other third parties receiving such contractual payments include: Commonwealth Equity Services, Inc., Dorsey Wright and Associates, LLC, E*Trade Securities LLC, FDx Advisors, Inc., Ladenburg Thalmann Advisor Network LLC, LPL Financial LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, Morgan Stanley Smith Barney LLC, Orion Advisors Services, LLC, Pershing LLC, Raymond James Financial Services, Inc., TD Ameritrade, Inc. and UBS Financial Services Inc. Any additions, modifications, or deletions to Intermediaries and other third parties listed above that have occurred since the date of this SAI are not included in the list.

Further, BFA Entities make Education Costs and Publishing Costs payments to other Intermediaries that are not listed above. BFA Entities may determine to make such payments based on any number of metrics. For example, BFA Entities may make payments at year-end or other intervals in a fixed amount, an amount based upon an Intermediary’s services at defined levels or an amount based on the Intermediary’s net sales of one or more iShares funds in a year or other period, any of which arrangements may include an agreed-upon minimum or maximum payment, or any combination of the foregoing. As of the date of this SAI, BFA anticipates that the payments paid by BFA Entities in connection with the Fund, iShares funds and exchange-traded products in general will be immaterial to BFA Entities in the aggregate for the next year. Please contact your salesperson or other investment professional for more information regarding any such payments or financial incentives his or her Intermediary firm may receive. Any payments made, or financial incentives offered, by the BFA Entities to an Intermediary may create the incentive for the Intermediary to encourage customers to buy shares of the Fund, other iShares funds or other exchange-traded products.

then be credited by the exchange to one or more market makers that meet or exceed liquidity and market quality standards with respect to the securities of the Fund. Each market maker incentive program is subject to approval from the SEC. Any such fee payments made to an exchange will be made by an affiliate of the Fund solely for the benefit of the Fund and will not be paid from any Fund assets. Other funds managed by BFA may also participate in such programs.

Valuation of Shares. The NAV for the Fund is generally calculated as of the close of business on the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each business day the NYSE is open. Valuation of securities held by the Fund is as follows:

Equity Investments. Equity securities traded on a recognized securities exchange (e.g., NYSE), on separate trading boards of a securities exchange or through a market system that provides contemporaneous transaction pricing information (each, an “Exchange”) are valued using information obtained via independent pricing services, generally at the closing price on the Exchange on which the security is primarily traded, or if an Exchange closing price is not available, the last traded price on that Exchange prior to the time as of which the Fund’s assets or liabilities are valued. However, under certain circumstances, other means of determining current market value may be used. If an equity security is traded on more than one Exchange, the current market value of the security where it is primarily traded generally will be used. In the event that there are no sales involving an equity security held by the Fund on a day on which the Fund values such security, the prior day’s price will be used, unless, in accordance with valuation procedures approved by the Board (the “Valuation Procedures”), BlackRock determines in good faith that such prior day’s price no longer reflects the fair value of the security, in which case such asset would be treated as a Fair Value Asset (as defined below).

Fixed-Income Investments. Fixed-income securities for which market quotations are readily available are generally valued using such securities’ current market value. The Fund values fixed-income portfolio securities using the last available bid prices or current market quotations provided by dealers or prices (including evaluated prices) supplied by the Fund’s approved independent third-party pricing services, each in accordance with the Valuation Procedures. The pricing services may use matrix pricing or valuation models that utilize certain inputs and assumptions to derive values, including transaction data (e.g., recent representative bids and offers), credit quality information, perceived market movements, news, and other relevant information and by other methods, which may include consideration of: yields or prices of securities of comparable quality, coupon, maturity and type; indications as to values from dealers; general market conditions; and/or other factors and assumptions. Pricing services generally value fixed-income securities assuming orderly transactions of an institutional round lot size, but the Fund may hold or transact in such securities in smaller, odd lot sizes. Odd lots may trade at lower prices than institutional round lots. The amortized cost method of valuation may be used with respect to debt obligations with sixty days or less remaining to maturity unless BlackRock determines in good faith that such method does not represent fair value. Loan participation notes are generally valued at the mean of the last available bid prices from one or more brokers or dealers as obtained from independent third-party pricing services. Certain fixed-income investments, including asset-backed and mortgage-related securities, may be valued based on valuation models that consider the estimated cash flows of each tranche of the entity, establish a benchmark yield and develop an estimated tranche-specific spread to the benchmark yield based on the unique attributes of the tranche.

Options, Futures, Swaps and Other Derivatives. Exchange-traded equity options for which market quotations are readily available are valued at the mean of the last bid and ask prices as quoted on the Exchange or the board of trade on which such options are traded. In the event that there is no mean price available for an exchange traded equity option held by the Fund on a day on which the Fund values such option, the last bid (long positions) or ask (short positions) price, if available, will be used as the value of such option. If no such bid or ask price is available on a day on which the Fund values such option, the prior day’s price will be used, unless BlackRock determines in good faith that such prior day’s price no longer reflects the fair value of the option, in which case such option will be treated as a Fair Value Asset (as defined below). OTC derivatives are valued using the last available bid prices or current market quotations provided by dealers or prices (including evaluated prices) supplied by the Fund’s approved independent third-party pricing services, each in accordance with the Valuation Procedures. OTC derivatives may be valued using a mathematical model which may incorporate a number of market data factors. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their settle price as of the close of such exchanges. Swap agreements and other derivatives are generally valued daily based upon quotations from market makers or by a pricing service in accordance with the Valuation Procedures.

Underlying Funds. Shares of underlying ETFs will be valued at their most recent closing price on an Exchange. Shares of underlying money market funds will be valued at their NAV.

General Valuation Information. The price the Fund could receive upon the sale of any particular portfolio investment may differ from the Fund’s valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair valuation methodology or a price provided by an independent pricing service. As a result, the price received upon the sale of an investment may be less than the value ascribed by the Fund, and the Fund could realize a greater than expected loss or lesser than expected gain upon the sale of the investment. The Fund’s ability to value its investment may also be impacted by technological issues and/or errors by pricing services or other third-party service providers.

All cash, receivables and current payables are carried on the Fund’s books at their face value.

Prices obtained from independent third-party pricing services, broker-dealers or market makers to value the Fund’s securities and other assets and liabilities are based on information available at the time the Fund values its assets and liabilities. In the event that a pricing service quotation is revised or updated subsequent to the day on which the Fund valued such security or other asset or liability, the revised pricing service quotation generally will be applied prospectively. Such determination will be made considering pertinent facts and circumstances surrounding the revision.

In the event that application of the methods of valuation discussed above result in a price for a security which is deemed not to be representative of the fair market value of such security, the security will be valued by, under the direction of or in accordance with a method approved by the Board as reflecting fair value. All other assets and liabilities (including securities for which market quotations are not readily available) held by the Fund (including restricted securities) are valued at fair value as determined in good faith by the Board or by BlackRock (its delegate) pursuant to the Valuation Procedures. Any assets and liabilities that are denominated in a foreign currency are converted into U.S. dollars using prevailing market rates on the date of valuation as quoted by one or more data service providers.

Certain of the securities acquired by the Fund may be traded on foreign exchanges or OTC markets on days on which the Fund’s NAV is not calculated. In such cases, the NAV of the Fund’s shares may be significantly affected on days when Authorized Participants can neither purchase nor redeem shares of the Fund.

Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used in the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

Fair Value. When market quotations are not readily available or are believed in good faith by BlackRock to be unreliable, the Fund’s investments are valued at fair value (“Fair Value Assets”). Fair Value Assets are valued by BlackRock in accordance with the Valuation Procedures. BlackRock may reasonably conclude that a market quotation is not readily available or is unreliable if, among other things, a security or other asset or liability does not have a price source due to its complete lack of trading, if BlackRock believes in good faith that a market quotation from a broker-dealer or other source is unreliable (e.g., where it varies significantly from a recent trade, or no longer reflects the fair value of the security or other asset or liability subsequent to the most recent market quotation), or where the security or other asset or liability is only thinly traded or due to the occurrence of a significant event subsequent to the most recent market quotation. For this purpose, a “significant event” is deemed to occur if BlackRock determines, in its reasonable business judgment, that an event has occurred after the close of trading for an asset or liability but prior to or at the time of pricing the Fund’s assets or liabilities, and that the event is likely to cause a material change to the closing market price of the assets or liabilities held by the Fund. Non-U.S. securities whose values are affected by volatility that occurs in the markets or in related or highly correlated assets (e.g., ADRs, GDRs or ETFs that invest in components of the Underlying Index) on a trading day after the close of non-U.S. securities markets may be fair valued. On any day the NYSE is open and a foreign market or the primary exchange on which a foreign asset or liability is traded is closed, such asset or liability will be valued using the prior day’s price, provided that BlackRock is not aware of any significant event or other information that would cause such price to no longer reflect the fair value of the asset or liability, in which case such asset or liability would be treated as a Fair Value Asset.

BlackRock, with input from the BlackRock Investment Strategy Group, will submit its recommendations regarding the valuation and/or valuation methodologies for Fair Value Assets to BlackRock’s Valuation Committee. The BlackRock Valuation Committee may accept, modify or reject any recommendations. In addition, the Fund’s accounting agent periodically endeavors to confirm the prices it receives from all third-party pricing services, index providers and broker-dealers, and, with the assistance of BlackRock, to regularly evaluate the values assigned to the securities and other assets and liabilities of the Fund. The pricing of all Fair Value Assets is subsequently reported to and, where appropriate, ratified by the Board.

When determining the price for a Fair Value Asset, the BlackRock Valuation Committee (or BlackRock’s Pricing Group) will seek to determine the price that the Fund might reasonably expect to receive upon the current sale of that asset or liability in an arm’s-length transaction on the date on which the assets or liabilities are being valued, and does not seek to determine the price that the Fund might expect to receive for selling the asset, or the cost of extinguishing a liability, at a later time or if it holds the asset or liability to maturity. Fair value determinations will be based upon all available factors that the BlackRock Valuation Committee (or BlackRock’s Pricing Group) deems relevant at the time of the determination, and may be based on analytical values determined by BlackRock using proprietary or third-party valuation models.

Fair value represents a good faith approximation of the value of an asset or liability. When determining the fair value of an asset, one or more of a variety of fair valuation methodologies may be used (depending on certain factors, including the asset type). For example, the asset may be priced on the basis of the original cost of the investment or, alternatively, using proprietary or third-party models (including models that rely upon direct portfolio management pricing inputs and which reflect the significance attributed to the various factors and assumptions being considered). Prices of actual, executed or historical transactions in the relevant asset and/or liability (or related or comparable assets and/or liabilities) or, where appropriate, an appraisal by a third-party experienced in the valuation of similar assets and/or liabilities, may also be used as a basis for establishing the fair value of an asset or liability. The fair value of one or more assets or liabilities may not, in retrospect, be the price at which those assets or liabilities could have been sold during the period in which the particular fair values were used in determining the Fund’s NAV. As a result, the Fund’s sale or redemption of its shares at NAV, at a time when a holding or holdings are valued at fair value, may have the effect of diluting or increasing the economic interest of existing shareholders.

The Fund’s annual audited financial statements, which are prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”), follow the requirements for valuation set forth in Financial Accounting Standards Board Accounting Standards Codification Topic 820, “Fair Value Measurements and Disclosures” (“ASC 820”), which defines and establishes a framework for measuring fair value under US GAAP and expands financial statement disclosure requirements relating to fair value measurements. Generally, ASC 820 and other accounting rules applicable to funds and various assets in which they invest are evolving. Such changes may adversely affect the Fund. For example, the evolution of rules governing the determination of the fair market value of assets or liabilities to the extent such rules become more stringent would tend to increase the cost and/or reduce the availability of third-party determinations of fair market value. This may in turn increase the costs associated with selling assets or affect their liquidity due to the Fund’s inability to obtain a third-party determination of fair market value.

Brokerage Transactions

Subject to policies established by the Board, BFA is primarily responsible for the execution of the Fund’s portfolio transactions and the allocation of brokerage. BFA does not execute transactions through any particular broker or dealer, but seeks to obtain the best net results for the Fund, taking into account such factors as price (including the applicable brokerage commission or dealer spread), size of order, difficulty of execution, operational facilities of the firm and the firm’s risk and skill in positioning blocks of securities. While BFA generally seeks reasonable trade execution costs, the Fund does not necessarily pay the lowest spread or commission available, and payment of the lowest commission or spread is not necessarily consistent with obtaining the best price and execution in particular transactions. Subject to applicable legal requirements, BFA may select a broker based partly upon brokerage or research services provided to BFA and its clients, including the Fund. In return for such services, BFA may cause the Fund to pay a higher commission than other brokers would charge if BFA determines in good faith that the commission is reasonable in relation to the services provided.

security or instrument being traded and the markets in which it is purchased or sold; (ii) the desired timing of the transaction; (iii) BFA’s knowledge of the expected commission rates and spreads currently available; (iv) the activity existing and expected in the market for the particular security or instrument, including any anticipated execution difficulties; (v) the full range of brokerage services provided; (vi) the broker’s or dealer’s capital; (vii) the quality of research and research services provided; (viii) the reasonableness of the commission, dealer spread or its equivalent for the specific transaction; and (ix) BFA’s knowledge of any actual or apparent operational problems of a broker or dealer. Brokers may also be selected because of their ability to handle special or difficult executions, such as may be involved in large block trades, less liquid securities, or other circumstances.

When transacting in securities traded on a non-U.S. exchange or in the secondary market, the Fund will generally be required to trade through a locally-licensed firm. As a result, the Fund may be more limited in the number of firms it will be able to select from in seeking to obtain the best price and most favorable execution for the Fund.

Section 28(e) of the 1934 Act (“Section 28(e)”) permits a U.S. investment adviser, under certain circumstances, to cause an account to pay a broker or dealer a commission for effecting a transaction in securities that exceeds the amount another broker or dealer would have charged for effecting the same transaction in recognition of the value of brokerage and research services provided by that broker or dealer. This includes commissions paid on riskless principal transactions in securities under certain conditions.

From time to time, the Fund may purchase new issues of securities in a fixed price offering. In these situations, the broker may be a member of the selling group that will, in addition to selling securities, provide BFA with research services. FINRA has adopted rules expressly permitting these types of arrangements under certain circumstances. Generally, the broker will provide research “credits” in these situations at a rate that is higher than that available for typical secondary market transactions. These arrangements may not fall within the safe harbor of Section 28(e).

The Fund anticipates that brokerage transactions involving foreign equity securities generally will be conducted primarily on the principal stock exchanges of the applicable country. Foreign equity securities may be held by the Fund in the form of depositary receipts, or other securities convertible into foreign equity securities. Depositary receipts may be listed on stock exchanges, or traded in OTC markets in the U.S. or Europe, as the case may be. ADRs, like other securities traded in the U.S., will be subject to negotiated commission rates.

OTC issues, including most fixed-income securities such as corporate debt and U.S. Government securities, are normally traded on a “net” basis without a stated commission, through dealers acting for their own account and not as brokers. The Fund will primarily engage in transactions with these dealers or deal directly with the issuer unless a better price or execution could be obtained by using a broker. Prices paid to a dealer with respect to both foreign and domestic securities will generally include a “spread,” which is the difference between the prices at which the dealer is willing to purchase and sell the specific security at the time, and includes the dealer’s normal profit.

Under the 1940 Act, persons affiliated with the Fund and persons who are affiliated with such affiliated persons are prohibited from dealing with the Fund as principal in the purchase and sale of securities unless a permissive order allowing such transactions is obtained from the SEC. Since transactions in the OTC market usually involve transactions with the dealers acting as principal for their own accounts, the Fund will not deal with affiliated persons and affiliated persons of such affiliated persons, including PNC and its affiliates, in connection with such transactions. The Fund will not purchase securities during the existence of any underwriting or selling group relating to such securities of which BFA, PNC, BRIL or any affiliated person (as defined in the 1940 Act) thereof is a member except pursuant to procedures adopted by the Board in accordance with Rule 10f-3 under the 1940 Act.

Purchases of money market instruments by the Fund are made from dealers, underwriters and issuers. The Fund does not currently expect to incur any brokerage commission expense on such transactions because money market instruments are generally traded on a “net” basis with dealers acting as principal for their own accounts without a stated commission. The price of the security, however, usually includes a profit to the dealer.

BFA may, from time to time, effect trades on behalf of and for the account of the Fund with brokers or dealers that are affiliated with BFA, in conformity with Rule 17e-1 under the 1940 Act and SEC rules and regulations. Under these provisions, any commissions paid to affiliated brokers or dealers must be reasonable and fair compared to the commissions charged by other brokers or dealers in comparable transactions.

Securities purchased in underwritten offerings include a fixed amount of compensation to the underwriter, generally referred to as the underwriter’s concession or discount. When securities are purchased or sold directly from or to an issuer, no commissions or discounts are paid.

Investment decisions for the Fund and for other investment accounts managed by BFA and the other Affiliates are made independently of each other in light of differing conditions. A variety of factors will be considered in making investment allocations. These factors include: (i) investment objectives or strategies for particular accounts, including sector, industry, country or region and capitalization weightings; (ii) tax considerations of an account; (iii) risk or investment concentration parameters for an account; (iv) supply or demand for a security at a given price level; (v) size of available investment; (vi) cash availability and liquidity requirements for accounts; (vii) regulatory restrictions; (viii) minimum investment size of an account; (ix) relative size of account; and (x) such other factors as may be approved by BlackRock’s general counsel. Moreover, investments may not be allocated to one client account over another based on any of the following considerations: (i) to favor one client account at the expense of another; (ii) to generate higher fees paid by one client account over another or to produce greater performance compensation to BlackRock; (iii) to develop or enhance a relationship with a client or prospective client; (iv) to compensate a client for past services or benefits rendered to BlackRock or to induce future services or benefits to be rendered to BlackRock; or (v) to manage or equalize investment performance among different client accounts. BFA and the other Affiliates may deal, trade and invest for their own respective accounts in the types of securities in which the Fund may invest.

Initial public offerings (“IPOs”) of securities may be over-subscribed and subsequently trade at a premium in the secondary market. When BFA is given an opportunity to invest in such an initial offering or “new” or “hot” issue, the supply of securities available for client accounts is often less than the amount of securities the accounts would otherwise take. In order to allocate these investments fairly and equitably among client accounts over time, each portfolio manager or a member of his or her respective investment team will indicate to BFA’s trading desk their level of interest in a particular offering with respect to eligible clients’ accounts for which that team is responsible. IPOs of U.S. equity securities will be identified as eligible for particular client accounts that are managed by portfolio teams who have indicated interest in the offering based on market capitalization of the issuer of the security and the investment mandate of the client account and in the case of international equity securities, the country where the offering is taking place and the investment mandate of the client account. Generally, shares received during the IPO will be allocated among participating client accounts within each investment mandate on a pro rata basis. This pro rata allocation may result in the Fund receiving less of a particular security than if pro-rating had not occurred. All allocations of securities will be subject, where relevant, to share minimums established for accounts and compliance constraints. In situations where supply is too limited to be allocated among all accounts for which the investment is eligible, portfolio managers may rotate such investment opportunities among one or more accounts so long as the rotation system provides for fair access for all client accounts over time. Other allocation methodologies that are considered by BFA to be fair and equitable to clients may be used as well.

Because different accounts may have differing investment objectives and policies, BFA may buy and sell the same securities at the same time for different clients based on the particular investment objective, guidelines and strategies of those accounts. For example, BFA may decide that it may be entirely appropriate for a growth fund to sell a security at the same time a value fund is buying that security. To the extent that transactions on behalf of more than one client of BFA or the other Affiliates during the same period may increase the demand for securities being purchased or the supply of securities being sold, there may be an adverse effect on price. For example, sales of a security by BlackRock on behalf of one or more of its clients may decrease the market price of such security, adversely impacting other BlackRock clients that still hold the security. If purchases or sales of securities arise for consideration at or about the same time that would involve the Fund or other clients or funds for which BFA or another Affiliate act as investment manager, transactions in such securities will be made, insofar as feasible, for the respective funds and clients in a manner deemed equitable to all.

be beneficial to the Fund. Transactions effected by BFA or the other Affiliates on behalf of more than one of its clients during the same period may increase the demand for securities being purchased or the supply of securities being sold, causing an adverse effect on price. The trader will give the bunched order to the broker-dealer that the trader has identified as being able to provide the best execution of the order. Orders for purchase or sale of securities will be placed within a reasonable amount of time of the order receipt and bunched orders will be kept bunched only long enough to execute the order.

The table below sets forth the brokerage commissions paid by the Fund for the fiscal years noted. Any differences in brokerage commissions paid by the Fund from year to year are principally due to increases or decreases in the Fund’s assets over those periods or the magnitude of changes to the components of the Fund's Underlying Index:

Fund Inception Date		Brokerage Commissions Paid During Fiscal Year Ended March 31, 2018		Brokerage Commissions Paid During Fiscal Year Ended March 31, 2017		Brokerage Commissions Paid During Fiscal Year Ended March 31, 2016
09/29/15		$68		$115		$119

The Fund did not pay any brokerage commissions to BRIL, an affiliate of BFA, or to any other broker-dealer that is part of the BlackRock group of companies, during the fiscal year ended March 31, 2018.

The Fund's purchase and sale orders for securities may be combined with those of other investment companies, clients or accounts that BlackRock manages or advises. If purchases or sales of portfolio securities of the Fund and one or more other accounts managed or advised by BlackRock are considered at or about the same time, transactions in such securities are allocated among the Fund and the other accounts in a manner deemed equitable to all by BlackRock. In some cases, this procedure could have a detrimental effect on the price or volume of the security as far as the Fund is concerned. However, in other cases, it is possible that the ability to participate in volume transactions and to negotiate lower transaction costs will be beneficial to the Fund. BlackRock may deal, trade and invest for its own account in the types of securities in which the Fund may invest. BlackRock may, from time to time, effect trades on behalf of and for the account of the Fund with brokers or dealers that are affiliated with BFA, in conformity with the 1940 Act and SEC rules and regulations. Under these provisions, any commissions paid to affiliated brokers or dealers must be reasonable and fair compared to the commissions charged by other brokers or dealers in comparable transactions. The Fund will not deal with affiliates in principal transactions unless permitted by applicable SEC rules or regulations, or by SEC exemptive order.

Portfolio turnover may vary from year to year, as well as within a year. High turnover rates may result in comparatively greater brokerage expenses. The table below sets forth the portfolio turnover rates of the Fund for the fiscal years noted:

	Fiscal Year Ended March 31, 2018		Fiscal Year Ended March 31, 2017
	11%		20%

Additional Information Concerning the Trust

Shares. The Trust currently consists of more than 280 separate investment series or portfolios called funds. The Trust issues shares of beneficial interests in the funds with no par value. The Board may designate additional iShares funds.

Each share issued by a fund has a pro rata interest in the assets of that fund. Shares have no preemptive, exchange, subscription or conversion rights and are freely transferable. Each share is entitled to participate equally in dividends and distributions declared by the Board with respect to the relevant fund, and in the net distributable assets of such fund on liquidation.

Each share has one vote with respect to matters upon which the shareholder is entitled to vote. In any matter submitted to shareholders for a vote, the fund shall hold a separate vote, provided that shareholders of all affected funds will vote together when: (i) required by the 1940 Act, or (ii) the Trustees determine that the matter affects the interests of more than one fund.

Act. All shares (regardless of the fund) have noncumulative voting rights in the election of members of the Board. Under Delaware law, Trustees of the Trust may be removed by vote of the shareholders.

Following the creation of the initial Creation Unit(s) of shares of a fund and immediately prior to the commencement of trading in the fund’s shares, a holder of shares may be a “control person” of the fund, as defined in Rule 0-1 under the 1940 Act. The fund cannot predict the length of time for which one or more shareholders may remain a control person of the fund.

Shareholders may make inquiries by writing to iShares Trust, c/o BlackRock Investments, LLC, 1 University Square Drive, Princeton, NJ 08540.

Absent an applicable exemption or other relief from the SEC or its staff, beneficial owners of more than 5% of the shares of a fund may be subject to the reporting provisions of Section 13 of the 1934 Act and the SEC’s rules promulgated thereunder. In addition, absent an applicable exemption or other relief from the SEC or its staff, officers and trustees of a fund and beneficial owners of 10% of the shares of the fund (“Insiders”) may be subject to the insider reporting, short-swing profit and short sale provisions of Section 16 of the 1934 Act and the SEC’s rules promulgated thereunder. Beneficial owners and Insiders should consult with their own legal counsel concerning their obligations under Sections 13 and 16 of the 1934 Act and existing guidance provided by the SEC staff.

In accordance with the Trust's current Agreement and Declaration of Trust (the “Declaration of Trust”), the Board may, without shareholder approval (unless such shareholder approval is required by the Declaration of Trust or applicable law, including the 1940 Act), authorize certain funds to merge, reorganize, consolidate, sell all or substantially all of their assets, or take other similar actions with, to or into another fund. The Trust or the Fund may be terminated by a majority vote of the Board, subject to the affirmative vote of a majority of the shareholders of the Trust or the Fund entitled to vote on termination; however, in certain circumstances described in the Declaration of Trust, only a majority vote of the Board is required. Although the shares are not automatically redeemable upon the occurrence of any specific event, the Declaration of Trust provides that the Board will have the unrestricted power to alter the number of shares in a Creation Unit. Therefore, in the event of a termination of the Trust or the Fund, the Board, in its sole discretion, could determine to permit the shares to be redeemable in aggregations smaller than Creation Units or to be individually redeemable. In such circumstance, the Trust or the Fund may make redemptions in-kind, for cash or for a combination of cash or securities. Further, in the event of a termination of the Trust or the Fund, the Trust or the Fund might elect to pay cash redemptions to all shareholders, with an in-kind election for shareholders owning in excess of a certain stated minimum amount.

DTC as Securities Depository for Shares of the Fund. Shares of the Fund are represented by securities registered in the name of DTC or its nominee and deposited with, or on behalf of, DTC.

DTC was created in 1973 to enable electronic movement of securities between its participants (“DTC Participants”), and NSCC was established in 1976 to provide a single settlement system for securities clearing and to serve as CCP for securities trades among DTC Participants. In 1999, DTC and NSCC were consolidated within The Depository Trust & Clearing Corporation (“DTCC”) and became wholly-owned subsidiaries of DTCC. The common stock of DTCC is owned by the DTC Participants, but NYSE and FINRA, through subsidiaries, hold preferred shares in DTCC that provide them with the right to elect one member each to the DTCC board of directors. Access to the DTC system is available to entities, such as banks, brokers, dealers and trust companies, that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly (“Indirect Participants”).

Beneficial ownership of shares is limited to DTC Participants, Indirect Participants and persons holding interests through DTC Participants and Indirect Participants. Ownership of beneficial interests in shares (owners of such beneficial interests are referred to herein as “Beneficial Owners”) is shown on, and the transfer of ownership is effected only through, records maintained by DTC (with respect to DTC Participants) and on the records of DTC Participants (with respect to Indirect Participants and Beneficial Owners that are not DTC Participants). Beneficial Owners will receive from or through the DTC Participant a written confirmation relating to their purchase of shares. The laws of some jurisdictions may require that certain purchasers of securities take physical delivery of such securities in definitive form. Such laws may impair the ability of certain investors to acquire beneficial interests in shares of the Fund.

Participant. The Trust shall provide each such DTC Participant with copies of such notice, statement or other communication, in such form, number and at such place as such DTC Participant may reasonably request, in order that such notice, statement or communication may be transmitted by such DTC Participant, directly or indirectly, to such Beneficial Owners. In addition, the Trust shall pay to each such DTC Participant a fair and reasonable amount as reimbursement for the expenses attendant to such transmittal, all subject to applicable statutory and regulatory requirements.

Share distributions shall be made to DTC or its nominee, Cede & Co., as the registered holder of all shares of the Trust. DTC or its nominee, upon receipt of any such distributions, shall credit immediately DTC Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in shares of the Fund as shown on the records of DTC or its nominee. Payments by DTC Participants to Indirect Participants and Beneficial Owners of shares held through such DTC Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a “street name,” and will be the responsibility of such DTC Participants.

The Trust has no responsibility or liability for any aspect of the records relating to or notices to Beneficial Owners, or payments made on account of beneficial ownership interests in such shares, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests, or for any other aspect of the relationship between DTC and the DTC Participants or the relationship between such DTC Participants and the Indirect Participants and Beneficial Owners owning through such DTC Participants. DTC may decide to discontinue providing its service with respect to shares of the Trust at any time by giving reasonable notice to the Trust and discharging its responsibilities with respect thereto under applicable law. Under such circumstances, the Trust shall take action to find a replacement for DTC to perform its functions at a comparable cost.

Distribution of Shares. In connection with the Fund's launch, the Fund was seeded through the sale of one or more Creation Units by the Fund to one or more initial investors. Initial investors participating in the seeding may be Authorized Participants, a lead market maker or other third party investor or an affiliate of the Fund or the Fund’s adviser. Each such initial investor may sell some or all of the shares underlying the Creation Unit(s) held by them pursuant to the registration statement for the Fund (each, a “Selling Shareholder”), which shares have been registered to permit the resale from time to time after purchase. The Fund will not receive any of the proceeds from the resale by the Selling Shareholders of these shares.

Selling Shareholders may sell shares owned by them directly or through broker-dealers, in accordance with applicable law, on any national securities exchange on which the shares may be listed or quoted at the time of sale, through trading systems, in the OTC market or in transactions other than on these exchanges or systems at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. These sales may be effected through brokerage transactions, privately negotiated trades, block sales, entry into options or other derivatives transactions or through any other means authorized by applicable law. Selling Shareholders may redeem the shares held in Creation Unit size by them through an Authorized Participant.

Any Selling Shareholder and any broker-dealer or agents participating in the distribution of shares may be deemed to be “underwriters” within the meaning of Section 2(a)(11) of the 1933 Act, in connection with such sales.

Any Selling Shareholder and any other person participating in such distribution will be subject to applicable provisions of the 1934 Act and the rules and regulations thereunder.

Creation and Redemption of Creation Units

General. The Trust issues and sells shares of the Fund only in Creation Units on a continuous basis through the Distributor or its agent, without a sales load, at a price based on the Fund's NAV next determined after receipt, on any Business Day (as defined below), of an order received by the Distributor or its agent in proper form. On days when the Listing Exchange closes earlier than normal, the Fund may require orders to be placed earlier in the day. The following table sets forth the number of shares of the Fund that constitute a Creation Unit for the Fund and the approximate value of such Creation Unit as of April 30, 2018:

Shares Per Creation Unit		Approximate Value Per Creation Unit (U.S.$)

In its discretion, the Trust reserves the right to increase or decrease the number of the Fund’s shares that constitute a Creation Unit. The Board reserves the right to declare a split or a consolidation in the number of shares outstanding of the Fund, and to make a corresponding change in the number of shares constituting a Creation Unit, in the event that the per share price in the secondary market rises (or declines) to an amount that falls outside the range deemed desirable by the Board.

A “Business Day” with respect to the Fund is any day on which the Listing Exchange on which the Fund is listed for trading is open for business. As of the date of this SAI, the Listing Exchange observes the following holidays, as observed: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

Fund Deposit. The consideration for purchase of Creation Units of the Fund generally consists of Deposit Securities and the Cash Component computed as described below. Together, the Deposit Securities and the Cash Component constitute the “Fund Deposit,” which, when combined with the Fund’s portfolio securities is designed to generate performance that has a collective investment profile similar to that of the Underlying Index. The Fund Deposit represents the minimum initial and subsequent investment amount for a Creation Unit of the Fund.

The “Cash Component” is an amount equal to the difference between the NAV of the shares (per Creation Unit) and the “Deposit Amount,” which is an amount equal to the market value of the Deposit Securities, and serves to compensate for any differences between the NAV per Creation Unit and the Deposit Amount. Payment of any stamp duty or other similar fees and expenses payable upon transfer of beneficial ownership of the Deposit Securities are the sole responsibility of the Authorized Participant purchasing the Creation Unit.

BFA makes available through the NSCC on each Business Day prior to the opening of business on the Listing Exchange, the list of names and the required number of shares of each Deposit Security and the amount of the Cash Component to be included in the current Fund Deposit (based on information as of the end of the previous Business Day for the Fund). Such Fund Deposit is applicable, subject to any adjustments as described below, to purchases of Creation Units of shares of the Fund until such time as the next-announced Fund Deposit is made available.

The identity and number of shares of the Deposit Securities change pursuant to changes in the composition of the Fund's portfolio and as rebalancing adjustments and corporate action events are reflected from time to time by BFA with a view to the investment objective of the Fund. The composition of the Deposit Securities may also change in response to adjustments to the weighting or composition of the component securities constituting the Underlying Index.

The Fund reserves the right to permit or require the substitution of a “cash in lieu” amount to be added to the Cash Component to replace any Deposit Security that may not be available in sufficient quantity for delivery or that may not be eligible for transfer through DTC or the clearing process (as discussed below) or that the Authorized Participant is not able to trade due to a trading restriction. The Fund also reserves the right to permit or require a “cash in lieu” amount in certain circumstances, including circumstances in which the delivery of the Deposit Security by the Authorized Participant would be restricted under applicable securities or other local laws or in certain other situations.

Cash Purchase Method. Although the Trust does not generally permit partial or full cash purchases of Creation Units of its funds, when partial or full cash purchases of Creation Units are available or specified for the Fund, they will be effected in essentially the same manner as in-kind purchases thereof. In the case of a partial or full cash purchase, the Authorized Participant must pay the cash equivalent of the Deposit Securities it would otherwise be required to provide through an in-kind purchase, plus the same Cash Component required to be paid by an in-kind purchaser.

redemptions of Creation Units (“Authorized Participant Agreement”) (discussed below). A Participating Party or DTC Participant who has executed an Authorized Participant Agreement is referred to as an “Authorized Participant.” All shares of the Fund, however created, will be entered on the records of DTC in the name of Cede & Co. for the account of a DTC Participant.

Role of the Authorized Participant. Creation Units may be purchased only by or through a DTC Participant that has entered into an Authorized Participant Agreement with the Distributor (an “Authorized Participant”). Such Authorized Participant will agree, pursuant to the terms of such Authorized Participant Agreement and on behalf of itself or any investor on whose behalf it will act, to certain conditions, including that such Authorized Participant will make available in advance of each purchase of shares an amount of cash sufficient to pay the Cash Component, once the net asset value of a Creation Unit is next determined after receipt of the purchase order in proper form, together with the transaction fees described below. An Authorized Participant, acting on behalf of an investor, may require the investor to enter into an agreement with such Authorized Participant with respect to certain matters, including payment of the Cash Component. Investors who are not Authorized Participants must make appropriate arrangements with an Authorized Participant. Investors should be aware that their particular broker may not be a DTC Participant or may not have executed an Authorized Participant Agreement and that orders to purchase Creation Units may have to be placed by the investor's broker through an Authorized Participant. As a result, purchase orders placed through an Authorized Participant may result in additional charges to such investor. The Trust does not expect to enter into an Authorized Participant Agreement with more than a small number of DTC Participants. A list of current Authorized Participants may be obtained from the Distributor. The Distributor has adopted guidelines regarding Authorized Participants’ transactions in Creation Units that are made available to all Authorized Participants. These guidelines set forth the processes and standards for Authorized Participants to transact with the Distributor and its agents in connection with creation and redemption transactions. In addition, the Distributor may be appointed as the proxy of the Authorized Participant and may be granted a power of attorney under its Authorized Participant Agreement.

Purchase Orders. To initiate an order for a Creation Unit, an Authorized Participant must submit to the Distributor or its agent an irrevocable order to purchase shares of the Fund, in proper form, generally before 4:00 p.m., Eastern time on any Business Day to receive that day’s NAV. The Distributor or its agent will notify BFA and the custodian of such order. The custodian will then provide such information to any appropriate sub-custodian. Procedures and requirements governing the delivery of the Fund Deposit are set forth in the procedures handbook for Authorized Participants and may change from time to time. Investors, other than Authorized Participants, are responsible for making arrangements for a creation request to be made through an Authorized Participant. The Distributor or its agent will provide a list of current Authorized Participants upon request. Those placing orders to purchase Creation Units through an Authorized Participant should allow sufficient time to permit proper submission of the purchase order to the Distributor or its agent by the Cutoff Time (as defined below) on such Business Day.

The Authorized Participant must also make available on or before the contractual settlement date, by means satisfactory to the Fund, immediately available or same day funds estimated by the Fund to be sufficient to pay the Cash Component next determined after acceptance of the purchase order, together with the applicable purchase transaction fees. Those placing orders should ascertain the deadline for cash transfers by contacting the operations department of the broker or depositary institution effectuating the transfer of the Cash Component. This deadline is likely to be significantly earlier than the Cutoff Time of the Fund. Investors should be aware that an Authorized Participant may require orders for purchases of shares placed with it to be in the particular form required by the individual Authorized Participant.

The Authorized Participant is responsible for any and all expenses and costs incurred by the Fund, including any applicable cash amounts, in connection with any purchase order.

Timing of Submission of Purchase Orders. An Authorized Participant must submit an irrevocable order to purchase shares of the Fund generally before 4:00 p.m., Eastern time on any Business Day in order to receive that day's NAV. Creation Orders must be transmitted by an Authorized Participant in the form required by the Fund to the Distributor or its agent pursuant to procedures set forth in the Authorized Participant Agreement. Economic or market disruptions or changes, or telephone or other communication failure, may impede the ability to reach the Distributor or its agent or an Authorized Participant. Orders to create shares of the Fund that are submitted on the Business Day immediately preceding a holiday or a day (other than a weekend) when the equity markets in the relevant non-U.S. market are closed may not be accepted. The Fund's deadline specified above for the submission of purchase orders is referred to as the Fund's “Cutoff Time.” The Distributor or its agent, in their discretion, may permit the submission of such orders and requests by or through an Authorized Participant at any time (including on days on which the Listing Exchange is not open for business) via communication through the facilities of

the Distributor's or its agent's proprietary website maintained for this purpose. Purchase orders and redemption requests, if accepted by the Trust, will be processed based on the NAV next determined after such acceptance in accordance with the Fund's Cutoff Times as provided in the Authorized Participant Agreement and disclosed in this SAI.

Acceptance of Orders for Creation Units. Subject to the conditions that (i) an irrevocable purchase order has been submitted by the Authorized Participant (either on its own or another investor's behalf) and (ii) arrangements satisfactory to the Fund are in place for payment of the Cash Component and any other cash amounts which may be due, the Fund will accept the order, subject to the Fund's right (and the right of the Distributor and BFA) to reject any order until acceptance, as set forth below.

Once the Fund has accepted an order, upon the next determination of the net asset value of the shares, the Fund will confirm the issuance of a Creation Unit, against receipt of payment, at such net asset value. The Distributor or its agent will then transmit a confirmation of acceptance to the Authorized Participant that placed the order.

The Fund reserves the absolute right to reject or revoke a creation order transmitted to it by the Distributor or its agent if (i) the order is not in proper form; (ii) the investor(s), upon obtaining the shares ordered, would own 80% or more of the currently outstanding shares of the Fund; (iii) the Deposit Securities delivered do not conform to the identity and number of shares specified, as described above; (iv) acceptance of the Deposit Securities would have certain adverse tax consequences to the Fund; (v) acceptance of the Fund Deposit would, in the opinion of counsel, be unlawful; (vi) acceptance of the Fund Deposit would, in the discretion of the Fund or BFA, have an adverse effect on the Fund or the rights of beneficial owners; or (vii) circumstances outside the control of the Fund, the Distributor or its agent and BFA make it impracticable to process purchase orders. The Distributor or its agent shall notify a prospective purchaser of a Creation Unit and/or the Authorized Participant acting on behalf of such purchaser of its rejection of such order. The Fund, State Street, the sub-custodian and the Distributor or its agent are under no duty, however, to give notification of any defects or irregularities in the delivery of Fund Deposits nor shall any of them incur any liability for failure to give such notification.

Issuance of a Creation Unit. Except as provided herein, a Creation Unit will not be issued until the transfer of good title to the Fund of the Deposit Securities and the payment of the Cash Component have been completed. When the sub-custodian has confirmed to the custodian that the securities included in the Fund Deposit (or the cash value thereof) have been delivered to the account of the relevant sub-custodian or sub-custodians, the Distributor or its agent and BFA shall be notified of such delivery and the Fund will issue and cause the delivery of the Creation Unit. Creation Units are generally issued on a “T+2 basis” (i.e., two Business Days after trade date). However, the Fund reserves the right to settle Creation Unit transactions on a basis other than T+2, including a shorter settlement period, if necessary or appropriate under the circumstances and compliant with applicable law. For example, the Fund reserves the right to settle Creation Unit transactions on a basis other than T+2 in order to accommodate non-U.S. market holiday schedules (as discussed in Appendix B of this SAI), to account for different treatment among non-U.S. and U.S. markets of dividend record dates and ex-dividend dates (i.e., the last day the holder of a security can sell the security and still receive dividends payable on the security) and in certain other circumstances.

To the extent contemplated by an Authorized Participant Agreement with the Distributor, the Fund will issue Creation Units to such Authorized Participant, notwithstanding the fact that the corresponding Fund Deposits have not been received in part or in whole, in reliance on the undertaking of the Authorized Participant to deliver the missing Deposit Securities as soon as possible, which undertaking shall be secured by such Authorized Participant's delivery and maintenance of collateral having a value at least equal to 105% and up to 115%, which percentage BFA may change at any time, in its sole discretion, of the value of the missing Deposit Securities in accordance with the Fund's then-effective procedures. The Trust may use such cash deposit at any time to buy Deposit Securities for the Fund. The only collateral that is acceptable to the Fund is cash in U.S. dollars. Such cash collateral must be delivered no later than the time specified by the Fund or its custodian on the contractual settlement date. The cash collateral posted by the Authorized Participant may be invested at the risk of the Authorized Participant, and income, if any, on invested cash collateral will be paid to that Authorized Participant. Information concerning the Fund's current procedures for collateralization of missing Deposit Securities is available from the Distributor or its agent. The Authorized Participant Agreement will permit the Fund to buy the missing Deposit Securities at any time and will subject the Authorized Participant to liability for any shortfall between the cost to the Fund of purchasing such securities and the cash collateral including, without limitation, liability for related brokerage, borrowings and other charges.

Authorized Participants that the creation and redemption transactions are for separate beneficial owners. All questions as to the number of shares of each security in the Deposit Securities and the validity, form, eligibility and acceptance for deposit of any securities to be delivered shall be determined by the Fund and the Fund's determination shall be final and binding.

Costs Associated with Creation Transactions. A standard creation transaction fee is imposed to offset the transfer and other transaction costs associated with the issuance of Creation Units. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same, regardless of the number of Creation Units purchased by the Authorized Participant on the applicable Business Day. If a purchase consists solely or partially of cash, the Authorized Participant may also be required to cover (up to the maximum amount shown below) certain brokerage, tax, foreign exchange, execution, price movement and other costs and expenses related to the execution of trades resulting from such transaction (which may, in certain instances, be based on a good faith estimate of transaction costs). Authorized Participants will also bear the costs of transferring the Deposit Securities to the Fund. Certain fees/costs associated with creation transactions may be waived in certain circumstances. Investors who use the services of a broker or other financial intermediary to acquire Fund shares may be charged a fee for such services.

The following table sets forth the Fund's standard creation transaction fees and maximum additional charge (as described above):

Standard Creation Transaction Fee		Maximum Additional Charge*
$100		3.0%

*	As a percentage of the net asset value per Creation Unit.

Redemption of Creation Units. Shares of the Fund may be redeemed by Authorized Participants only in Creation Units at their NAV next determined after receipt of a redemption request in proper form by the Distributor or its agent and only on a Business Day. The Fund will not redeem shares in amounts less than Creation Units. There can be no assurance, however, that there will be sufficient liquidity in the secondary market at any time to permit assembly of a Creation Unit. Investors should expect to incur brokerage and other costs in connection with assembling a sufficient number of shares to constitute a Creation Unit that could be redeemed by an Authorized Participant. Beneficial owners also may sell shares in the secondary market.

The Fund generally redeems Creation Units for Fund Securities (as defined below). Please see the Cash Redemption Method section below and the following discussion summarizing the in-kind method for further information on redeeming Creation Units of the Fund.

BFA makes available through the NSCC, prior to the opening of business on the Listing Exchange on each Business Day, the designated portfolio of securities (including any portion of such securities for which cash may be substituted) that will be applicable (subject to possible amendment or correction) to redemption requests received in proper form (as defined below) on that day (“Fund Securities”), and an amount of cash (the “Cash Amount,” as described below). Such Fund Securities and the corresponding Cash Amount (each subject to possible amendment or correction) are applicable, in order to effect redemptions of Creation Units of the Fund until such time as the next announced composition of the Fund Securities and Cash Amount is made available. Fund Securities received on redemption may not be identical to Deposit Securities that are applicable to creations of Creation Units. Procedures and requirements governing redemption transactions are set forth in the handbook for Authorized Participants and may change from time to time.

Unless cash redemptions are available or specified for the Fund, the redemption proceeds for a Creation Unit generally consist of Fund Securities, plus the Cash Amount, which is an amount equal to the difference between the net asset value of the shares being redeemed, as next determined after the receipt of a redemption request in proper form, and the value of Fund Securities, less a redemption transaction fee (as described below).

amount of cash paid out in such cases will be equivalent to the value of the substituted security listed as a Fund Security. In the event that the Fund Securities have a value greater than the NAV of the shares, a compensating cash payment equal to the difference is required to be made by or through an Authorized Participant by the redeeming shareholder. The Fund generally redeems Creation Units for Fund Securities, but the Fund reserves the right to utilize a cash option for redemption of Creation Units. The Fund may, in its sole discretion, provide such redeeming Authorized Participant a portfolio of securities that differs from the exact composition of the Fund Securities, but does not differ in NAV.

Cash Redemption Method. Although the Trust does not generally permit partial or full cash redemptions of Creation Units of its funds, when partial or full cash redemptions of Creation Units are available or specified for the Fund, they will be effected in essentially the same manner as in-kind redemptions thereof. In the case of partial or full cash redemption, the Authorized Participant receives the cash equivalent of the Fund Securities it would otherwise receive through an in-kind redemption, plus the same Cash Amount to be paid to an in-kind redeemer.

Costs Associated with Redemption Transactions. A standard redemption transaction fee is imposed to offset transfer and other transaction costs that may be incurred by the Fund. The standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by an Authorized Participant on the applicable Business Day. If a redemption consists solely or partially of cash, the Authorized Participant may also be required to cover (up to the maximum amount shown below) certain brokerage, tax, foreign exchange, execution, price movement and other costs and expenses related to the execution of trades resulting from such transaction (which may, in certain instances, be based on a good faith estimate of transaction costs). Authorized Participants will also bear the costs of transferring the Fund Securities from the Fund to their account on their order. Certain fees/costs associated with redemption transactions may be waived in certain circumstances. Investors who use the services of a broker or other financial intermediary to dispose of Fund shares may be charged a fee for such services.

The following table sets forth the Fund's standard redemption transaction fees and maximum additional charge (as described above):

Standard Redemption Transaction Fee		Maximum Additional Charge*
$100		2.0%

*	As a percentage of the net asset value per Creation Unit, inclusive of the standard redemption transaction fee.

Placement of Redemption Orders. Redemption requests for Creation Units of the Fund must be submitted to the Distributor or its agent by or through an Authorized Participant. An Authorized Participant must submit an irrevocable request to redeem shares of the Fund generally before 4:00 p.m., Eastern time on any Business Day in order to receive that day's NAV. On days when the Listing Exchange closes earlier than normal, the Fund may require orders to redeem Creation Units to be placed earlier that day. Investors, other than Authorized Participants, are responsible for making arrangements for a redemption request to be made through an Authorized Participant. The Distributor or its agent will provide a list of current Authorized Participants upon request.

The Authorized Participant must transmit the request for redemption in the form required by the Fund to the Distributor or its agent in accordance with procedures set forth in the Authorized Participant Agreement. Investors should be aware that their particular broker may not have executed an Authorized Participant Agreement and that, therefore, requests to redeem Creation Units may have to be placed by the investor's broker through an Authorized Participant who has executed an Authorized Participant Agreement. At any time, only a limited number of broker-dealers will have an Authorized Participant Agreement in effect. Investors making a redemption request should be aware that such request must be in the form specified by such Authorized Participant. Investors making a request to redeem Creation Units should allow sufficient time to permit proper submission of the request by an Authorized Participant and transfer of the shares to the Fund's transfer agent; such investors should allow for the additional time that may be required to effect redemptions through their banks, brokers or other financial intermediaries if such intermediaries are not Authorized Participants.

request in form satisfactory to the Fund is received by the Distributor or its agent from the Authorized Participant on behalf of itself or another redeeming investor within the time periods specified above; and (iii) all other procedures set forth in the Authorized Participant Agreement are properly followed.

Upon receiving a redemption request, the Distributor or its agent shall notify the Fund and the Fund's transfer agent of such redemption request. The tender of an investor's shares for redemption and the distribution of the securities and/or cash included in the redemption payment made in respect of Creation Units redeemed will be made through DTC and the relevant Authorized Participant to the Beneficial Owner thereof as recorded on the book-entry system of DTC or the DTC Participant through which such investor holds, as the case may be, or by such other means specified by the Authorized Participant submitting the redemption request.

A redeeming Authorized Participant, whether on its own account or acting on behalf of a Beneficial Owner, must maintain appropriate security arrangements with a qualified broker-dealer, bank or other custody providers in each jurisdiction in which any of the portfolio securities are customarily traded, to which account such portfolio securities will be delivered.

Deliveries of redemption proceeds by the Fund are generally made within two Business Days (i.e., “T+2”). However, the Fund reserves the right to settle redemption transactions on a basis other than T+2, including a shorter settlement period, if necessary or appropriate under the circumstances and compliant with applicable law. For example, the Fund reserves the right to settle redemption transactions on a basis other than T+2 in order to accommodate non-U.S. market holiday schedules (as discussed in Appendix B to this SAI), to account for different treatment among non-U.S. and U.S. markets of dividend record dates and dividend ex-dates (i.e., the last date the holder of a security can sell the security and still receive dividends payable on the security sold) and in certain other circumstances. Appendix B of this SAI identifies the instances, if any, where more than seven days would be needed to deliver redemption proceeds. Pursuant to an order of the SEC, the Trust will make delivery of redemption proceeds within the number of days stated in Appendix B of this SAI to be the maximum number of days necessary to deliver redemption proceeds.

If neither the redeeming Beneficial Owner nor the Authorized Participant acting on behalf of such redeeming Beneficial Owner has appropriate arrangements to take delivery of Fund Securities in the applicable non-U.S. jurisdiction and it is not possible to make other such arrangements, or if it is not possible to effect deliveries of Fund Securities in such jurisdiction, the Fund may in its discretion exercise its option to redeem such shares in cash, and the redeeming Beneficial Owner will be required to receive its redemption proceeds in cash. In such case, the investor will receive a cash payment equal to the net asset value of its shares based on the NAV of the Fund next determined after the redemption request is received in proper form (minus a redemption transaction fee and additional charges specified above to offset the Fund's brokerage and other transaction costs associated with the disposition of Fund Securities). Redemptions of shares for Fund Securities will be subject to compliance with applicable U.S. federal and state securities laws and the Fund (whether or not it otherwise permits cash redemptions) reserves the right to redeem Creation Units for cash to the extent that the Fund cannot lawfully deliver specific Fund Securities upon redemptions or cannot do so without first registering the Fund Securities under such laws.

Although the Trust does not ordinarily permit cash redemptions of Creation Units, in the event that cash redemptions are permitted or required by the Trust, proceeds will be paid to the Authorized Participant redeeming shares as soon as practicable after the date of redemption (within seven calendar days thereafter, except for the instances listed in the Appendix B to this SAI in which more than seven calendar days would be needed).

To the extent contemplated by an Authorized Participant's agreement with the Distributor or its agent, in the event an Authorized Participant has submitted a redemption request in proper form but is unable to transfer all or part of the Creation Unit to be redeemed to the Fund, at or prior to 10:00 a.m., Eastern time on the Listing Exchange business day after the date of submission of such redemption request, the Distributor or its agent will accept the redemption request in reliance on the undertaking by the Authorized Participant to deliver the missing shares as soon as possible. Such undertaking shall be secured by the Authorized Participant's delivery and maintenance of collateral consisting of cash, in U.S. dollars in immediately available funds, having a value at least equal to 105% and up to 115%, which percentage BFA may change at any time, in its sole discretion, of the value of the missing shares. Such cash collateral must be delivered no later than the time specified by the Fund or its custodian on the day after the date of submission of such redemption request and shall be held by State Street and marked-to-market daily. The fees of State Street and any sub-custodians in respect of the delivery, maintenance and redelivery of the cash collateral shall be payable by the Authorized Participant. The cash collateral posted by the Authorized Participant may be invested at the risk of the Authorized Participant, and income, if any, on invested cash

collateral will be paid to that Authorized Participant. The Authorized Participant Agreement permits the Fund to acquire shares of the Fund at any time and subjects the Authorized Participant to liability for any shortfall between the aggregate of the cost to the Fund of purchasing such shares, plus the value of the Cash Amount, and the value of the cash collateral together with liability for related brokerage and other charges.

Because the portfolio securities of the Fund may trade on exchange(s) on days that the Listing Exchange is closed or are otherwise not Business Days for the Fund, shareholders may not be able to redeem their shares of the Fund, or purchase or sell shares of the Fund on the Listing Exchange on days when the NAV of the Fund could be significantly affected by events in the relevant non-U.S. markets.

The right of redemption may be suspended or the date of payment postponed with respect to the Fund: (i) for any period during which the Listing Exchange is closed (other than customary weekend and holiday closings); (ii) for any period during which trading on the Listing Exchange is suspended or restricted; (iii) for any period during which an emergency exists as a result of which disposal of the shares of the Fund's portfolio securities or determination of its net asset value is not reasonably practicable; or (iv) in such other circumstance as is permitted by the SEC.

Taxation on Creations and Redemptions of Creation Units. An Authorized Participant generally will recognize either gain or loss upon the exchange of Deposit Securities for Creation Units. This gain or loss is calculated by taking the market value of the Creation Units purchased over the Authorized Participant’s aggregate basis in the Deposit Securities exchanged therefor. However, the IRS may apply the wash sales rules to determine that any loss realized upon the exchange of Deposit Securities for Creation Units is not currently deductible. Authorized Participants should consult their own tax advisors.

Current U.S. federal income tax laws dictate that capital gain or loss realized from the redemption of Creation Units will generally create long-term capital gain or loss if the Authorized Participant holds the Creation Units for more than one year, or short-term capital gain or loss if the Creation Units were held for one year or less, if the Creation Units are held as capital assets.

Taxes

The following is a summary of certain material U.S. federal income tax considerations regarding the purchase, ownership and disposition of shares of the Fund. This summary does not address all of the potential U.S. federal income tax consequences that may be applicable to the Fund or to all categories of investors, some of which may be subject to special tax rules. Current and prospective shareholders are urged to consult their own tax advisors with respect to the specific U.S. federal, state, local and non-U.S. tax consequences of investing in the Fund. The summary is based on the laws and judicial and administrative interpretations thereof in effect on the date of this SAI, all of which are subject to change, possibly with retroactive effect. References to the Fund will also generally apply to the Underlying Fund as well.

Tax reform legislation commonly known as the Tax Cuts and Jobs Act (the “Tax Act”) was enacted on December 22, 2017. The Tax Act makes significant changes to the U.S. federal income tax rules for individuals and corporations, generally effective for taxable years beginning after December 31, 2017. Most of the changes applicable to individuals are temporary and, without further legislation, will not apply after 2025. The application of certain provisions of the Tax Act is uncertain, and the changes in the act may have indirect effects on the Fund, its investments and its shareholders that cannot be predicted. In addition, legislative, regulatory or administrative changes could be enacted or promulgated at any time, either prospectively or with retroactive effect. Prospective investors should consult their tax advisors regarding the implications of the Tax Act on their investment in the Fund.

Regulated Investment Company Qualifications. The Fund intends to qualify for treatment as a separate RIC under Subchapter M of the Internal Revenue Code. To qualify for treatment as a RIC, the Fund must annually distribute at least 90% of its investment company taxable income (which includes dividends, interest and net short-term capital gains) and meet several other requirements. Among such other requirements are the following: (i) at least 90% of the Fund’s annual gross income must be derived from dividends, interest, payments with respect to securities loans, gains from the sale or other disposition of stock or securities or non-U.S. currencies, other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies, and net income derived from interests in qualified publicly-traded partnerships (i.e., partnerships that are traded on an established securities market or tradable on a secondary market, other than partnerships that derive at least 90% of their income from interest, dividends, capital gains and other traditionally permitted RIC income); and (ii) at the close of each quarter of the

Fund's taxable year, (a) at least 50% of the market value of the Fund’s total assets must be represented by cash and cash items, U.S. government securities, securities of other RICs and other securities, with such other securities limited for purposes of this calculation in respect of any one issuer to an amount not greater than 5% of the value of the Fund’s assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of the Fund's total assets may be invested in the securities (other than U.S. government securities or the securities of other RICs) of any one issuer, of two or more issuers of which 20% or more of the voting stock is held by the Fund and that are engaged in the same or similar trades or businesses or related trades or businesses, or the securities of one or more qualified publicly-traded partnerships.

The Fund may be able to cure a failure to derive at least 90% of its income from the sources specified above or a failure to diversify its holdings in the manner described above by paying a tax and/or by disposing of certain assets. If, in any taxable year, the Fund fails one of these tests and does not timely cure the failure, the Fund will be taxed in the same manner as an ordinary corporation and distributions to its shareholders will not be deductible by the Fund in computing its taxable income.

Although, in general, the passive loss rules of the Internal Revenue Code do not apply to RICs, such rules do apply to a RIC with respect to items attributable to interests in qualified publicly-traded partnerships. The Fund's investments in partnerships, including in qualified publicly-traded partnerships, may result in the Fund being subject to state, local, or non-U.S. income, franchise or withholding tax liabilities.

Taxation of RICs. As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its taxable investment income and capital gains that it distributes to its shareholders, provided that it satisfies a minimum distribution requirement. To satisfy the minimum distribution requirement, the Fund must distribute to its shareholders at least the sum of (i) 90% of its “investment company taxable income” (i.e., income other than its net realized long-term capital gain over its net realized short-term capital loss), plus or minus certain adjustments, and (ii) 90% of its net tax-exempt income for the taxable year. The Fund will be subject to income tax at regular corporate rates on any taxable income or gains that it does not distribute to its shareholders. If the Fund fails to qualify for any taxable year as a RIC or fails to meet the distribution requirement, all of its taxable income will be subject to tax at regular corporate income tax rates without any deduction for distributions to shareholders, and such distributions generally will be taxable to shareholders as ordinary dividends to the extent of the Fund’s current and accumulated earnings and profits. In such event, distributions to individuals should be eligible to be treated as qualified dividend income and distributions to corporate shareholders generally should be eligible for the dividends received deduction. Although the Fund intends to distribute substantially all of its net investment income and its capital gains for each taxable year, the Fund will be subject to U.S. federal income taxation to the extent any such income or gains are not distributed. If the Fund fails to qualify as a RIC in any year, it must pay out its earnings and profits accumulated in that year in order to qualify again as a RIC. If the Fund fails to qualify as a RIC for a period greater than two taxable years, the Fund may be required to recognize any net built-in gains with respect to certain of its assets (i.e., the excess of the aggregate gains, including items of income, over aggregate losses that would have been realized with respect to such assets if the Fund had been liquidated) if it qualifies as a RIC in a subsequent year.

Excise Tax. The Fund will be subject to a 4% excise tax on certain undistributed income if it does not distribute to its shareholders in each calendar year at least 98% of its ordinary income for the calendar year plus at least 98.2% of its capital gain net income for the 12 months ended October 31 of such year. For this purpose, however, any ordinary income or capital gain net income retained by the Fund that is subject to corporate income tax will be considered to have been distributed by year-end. In addition, the minimum amounts that must be distributed in any year to avoid the excise tax will be increased or decreased to reflect any underdistribution or overdistribution, as the case may be, from the previous year. The Fund intends to declare and distribute dividends and distributions in the amounts and at the times necessary to avoid the application of this 4% excise tax.

Net Capital Loss Carryforwards. Net capital loss carryforwards may be applied against any net realized capital gains in each succeeding year, until they have been reduced to zero.

In the event that the Fund were to experience an ownership change as defined under the Internal Revenue Code, the loss carryforwards and other favorable tax attributes of the Fund and the Underlying Fund, if any, may be subject to limitation.

The Fund had tax basis net capital loss carryforwards as set forth in the table below as of March 31, 2018, the tax year-end for the Fund:

Taxation of U.S. Shareholders. Dividends and other distributions by the Fund are generally treated under the Internal Revenue Code as received by the shareholders at the time the dividend or distribution is made. However, any dividend or distribution declared by the Fund in October, November or December of any calendar year and payable to shareholders of record on a specified date in such a month shall be deemed to have been received by each shareholder on December 31 of such calendar year and to have been paid by the Fund not later than such December 31, provided such dividend is actually paid by the Fund during January of the following calendar year.

The Fund intends to distribute annually to its shareholders substantially all of its investment company taxable income and any net realized long-term capital gains in excess of net realized short-term capital losses (including any capital loss carryovers). However, if the Fund retains for investment an amount equal to all or a portion of its net long-term capital gains in excess of its net short-term capital losses (including any capital loss carryovers), it will be subject to a corporate tax (at a flat rate of 21%) on the amount retained. In that event, the Fund will designate such retained amounts as undistributed capital gains in a notice to its shareholders who (a) will be required to include in income for U.S. federal income tax purposes, as long-term capital gains, their proportionate shares of the undistributed amount, (b) will be entitled to credit their proportionate shares of the tax paid by the Fund on the undistributed amount against their U.S. federal income tax liabilities, if any, and to claim refunds to the extent their credits exceed their liabilities, if any, and (c) will be entitled to increase their tax basis, for U.S. federal income tax purposes, in their shares by an amount equal to the excess of the amount in clause (a) over the amount in clause (b). Organizations or persons not subject to U.S. federal income tax on such capital gains will be entitled to a refund of their pro rata share of such taxes paid by the Fund upon filing appropriate returns or claims for refund with the IRS.

Distributions of net realized long-term capital gains, if any, that the Fund reports as capital gains dividends are taxable as long-term capital gains, whether paid in cash or in shares and regardless of how long a shareholder has held shares of the Fund. All other dividends of the Fund (including dividends from short-term capital gains) from its current and accumulated earnings and profits (“regular dividends”) are generally subject to tax as ordinary income, subject to the discussion of qualified dividend income below. Short-term capital gains earned by the Underlying Fund will be ordinary income when distributed to the Fund and will not be offset by the Fund’s capital losses. Long-term capital gains are eligible for taxation at a maximum rate of 15% or 20% for non-corporate shareholders, depending on whether their income exceeds certain threshold amounts.

If an individual receives a regular dividend qualifying for the long-term capital gains rates and such dividend constitutes an “extraordinary dividend,” and the individual subsequently recognizes a loss on the sale or exchange of stock in respect of which the extraordinary dividend was paid, then the loss will be long-term capital loss to the extent of such extraordinary dividend. An “extraordinary dividend” on common stock for this purpose is generally a dividend (i) in an amount greater than or equal to 10% of the taxpayer’s tax basis (or trading value) in a share of stock, aggregating dividends with ex-dividend dates within an 85-day period, or (ii) in an amount greater than 20% of the taxpayer’s tax basis (or trading value) in a share of stock, aggregating dividends with ex-dividend dates within a 365-day period.

Distributions in excess of the Fund’s current and accumulated earnings and profits will, as to each shareholder, be treated as a tax-free return of capital to the extent of a shareholder’s basis in shares of the Fund, and as a capital gain thereafter (if the shareholder holds shares of the Fund as capital assets). Distributions in excess of the Fund’s minimum distribution requirements, but not in excess of the Fund’s earnings and profits, will be taxable to shareholders and will not constitute nontaxable returns of capital. Shareholders receiving dividends or distributions in the form of additional shares should be treated for U.S. federal income tax purposes as receiving a distribution in an amount equal to the amount of money that the shareholders receiving cash dividends or distributions will receive and should have a cost basis in the shares received equal to such amount.

A 3.8% U.S. federal Medicare contribution tax is imposed on net investment income, including, but not limited to, interest, dividends, and net gain from investments, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly) and of estates and trusts.

may nevertheless be taxable to them. If the Fund is the holder of record of any security on the record date for any dividends payable with respect to such security, such dividends will be included in the Fund’s gross income not as of the date received but as of the later of (a) the date such security became ex-dividend with respect to such dividends (i.e., the date on which a buyer of the security would not be entitled to receive the declared, but unpaid, dividends); or (b) the date the Fund acquired such security. Accordingly, in order to satisfy its income distribution requirements, the Fund may be required to pay dividends based on anticipated earnings, and shareholders may receive dividends in an earlier year than would otherwise be the case.

In certain situations, the Fund may, for a taxable year, defer all or a portion of its net capital loss (or if there is no net capital loss, then any net long-term or short-term capital loss) realized after October and its late-year ordinary loss (defined as the sum of (i) the excess of post-October foreign currency and passive foreign investment company (“PFIC”) losses over post-October foreign currency and PFIC gains and (ii) the excess of post-December ordinary losses over post-December ordinary income) until the next taxable year in computing its investment company taxable income and net capital gain, which will defer the recognition of such realized losses. Such deferrals and other rules regarding gains and losses realized after October (or December) may affect the tax character of shareholder distributions.

Sales of Shares. Upon the sale or exchange of shares of the Fund, a shareholder will realize a taxable gain or loss equal to the difference between the amount realized and the shareholder’s basis in shares of the Fund. A redemption of shares by the Fund will be treated as a sale for this purpose. Such gain or loss will be treated as capital gain or loss if the shares are capital assets in the shareholder’s hands and will be long-term capital gain or loss if the shares are held for more than one year and short-term capital gain or loss if the shares are held for one year or less. Any loss realized on a sale or exchange will be disallowed to the extent the shares disposed of are replaced, including replacement through the reinvesting of dividends or capital gains distributions, or by an option or contract to acquire substantially identical shares, within a 61-day period beginning 30 days before and ending 30 days after the disposition of the shares. In such a case, the basis of the shares acquired will be increased to reflect the disallowed loss. Any loss realized by a shareholder on the sale of Fund shares held by the shareholder for six months or less will be treated for U.S. federal income tax purposes as a long-term capital loss to the extent of any distributions or deemed distributions of long-term capital gains received by the shareholder with respect to such share. The Medicare contribution tax described above will apply to the sale of Fund shares.

If a shareholder incurs a sales charge in acquiring shares of the Fund, disposes of those shares within 90 days and then, on or before January 31 of the following calendar year, acquires shares in a mutual fund for which the otherwise applicable sales charge is reduced by reason of a reinvestment right (e.g., an exchange privilege), the original sales charge will not be taken into account in computing gain/loss on the original shares to the extent the subsequent sales charge is reduced. Instead, the disregarded portion of the original sales charge will be added to the tax basis of the newly acquired shares. Furthermore, the same rule also applies to a disposition of the newly acquired shares made within 90 days of the second acquisition. This provision prevents shareholders from immediately deducting the sales charge by shifting their investments within a family of mutual funds.

Backup Withholding. In certain cases, the Fund will be required to withhold at a 24% rate and remit to the U.S. Treasury such amounts withheld from any distributions paid to a shareholder who: (i) has failed to provide a correct taxpayer identification number; (ii) is subject to backup withholding by the IRS; (iii) has failed to certify to the Fund that such shareholder is not subject to backup withholding; or (iv) has not certified that such shareholder is a U.S. person (including a U.S. resident alien). Backup withholding is not an additional tax and any amount withheld may be credited against a shareholder's U.S. federal income tax liability.

Sections 351 and 362. The Trust, on behalf of the Fund, has the right to reject an order for a purchase of shares of the Fund if the purchaser (or group of purchasers) would, upon obtaining the shares so ordered, own 80% or more of the outstanding shares of the Fund and if, pursuant to Sections 351 and 362 of the Internal Revenue Code, the Fund would have a basis in the securities different from the market value of such securities on the date of deposit. If the Fund’s basis in such securities on the date of deposit was less than market value on such date, the Fund, upon disposition of the securities, would recognize more taxable gain or less taxable loss than if its basis in the securities had been equal to market value. It is not anticipated that the Trust will exercise the right of rejection except in a case where the Trust determines that accepting the order could result in material adverse tax consequences to the Fund or its shareholders. The Trust also has the right to require information necessary to determine beneficial share ownership for purposes of the 80% determination.

Taxation of Certain Derivatives. The Fund’s transactions in zero coupon securities, non-U.S. currencies, forward contracts, options and futures contracts (including options and futures contracts on non-U.S. currencies), to the extent permitted, will be subject to special provisions of the Internal Revenue Code (including provisions relating to “hedging transactions” and “straddles”) that, among other consequences, may affect the character of gains and losses realized by the Fund (i.e., may affect whether gains or losses are ordinary or capital), accelerate recognition of income to the Fund and defer Fund losses. These rules could therefore affect the character, amount and timing of distributions to shareholders. These provisions also (a) will require the Fund to mark-to-market certain types of the positions in its portfolio (i.e., treat them as if they were closed out at the end of each year) and (b) may cause the Fund to recognize income without receiving cash with which to pay dividends or make distributions in amounts necessary to satisfy the distribution requirements for avoiding income and excise taxes. The Fund will monitor its transactions, will make the appropriate tax elections and will make the appropriate entries in its books and records when it acquires any zero coupon security, non-U.S. currency, forward contract, option, futures contract or hedged investment in order to mitigate the effect of these rules and prevent disqualification of the Fund as a RIC.

The Fund’s investments in so-called “Section 1256 contracts,” such as regulated futures contracts, most non-U.S. currency forward contracts traded in the interbank market and options on most security indexes, are subject to special tax rules. All Section 1256 contracts held by the Fund at the end of its taxable year are required to be marked to their market value, and any unrealized gain or loss on those positions will be included in the Fund’s income as if each position had been sold for its fair market value at the end of the taxable year. The resulting gain or loss will be combined with any gain or loss realized by the Fund from positions in Section 1256 contracts closed during the taxable year. Provided such positions were held as capital assets and were not part of a “hedging transaction” nor part of a “straddle,” 60% of the resulting net gain or loss will be treated as long-term capital gain or loss, and 40% of such net gain or loss will be treated as short-term capital gain or loss, regardless of the period of time the positions were actually held by the Fund.

As a result of entering into swap contracts, the Fund may make or receive periodic net payments. The Fund may also make or receive a payment when a swap is terminated prior to maturity through an assignment of the swap or other closing transaction. Periodic net payments will generally constitute ordinary income or deductions, while termination of a swap will generally result in capital gain or loss (which will be a long-term capital gain or loss if the Fund has been a party to the swap for more than one year). With respect to certain types of swaps, the Fund may be required to currently recognize income or loss with respect to future payments on such swaps or may elect under certain circumstances to mark such swaps to market annually for tax purposes as ordinary income or loss.

Qualified Dividend Income. Distributions by the Fund of investment company taxable income (including any short-term capital gains), whether received in cash or shares, will be taxable either as ordinary income or as qualified dividend income, which is eligible to be taxed at long-term capital gain rates to the extent the Fund receives qualified dividend income on the securities it holds and the Fund reports the distribution as qualified dividend income. Qualified dividend income is, in general, dividend income from taxable U.S. corporations (but generally not from U.S. REITs) and certain non-U.S. corporations (e.g., non-U.S. corporations that are not PFICs and which are incorporated in a possession of the U.S. or in certain countries with a comprehensive tax treaty with the U.S., or the stock of which is readily tradable on an established securities market in the U.S. (where the dividends are paid with respect to such stock)). Under current IRS guidance, the U.S. has appropriate comprehensive income tax treaties with the following countries: Australia, Austria, Bangladesh, Barbados, Belgium, Bulgaria, Canada, China (but not with Hong Kong, which is treated as a separate jurisdiction for U.S. tax purposes), Cyprus, the Czech Republic, Denmark, Egypt, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, India, Indonesia, Ireland, Israel, Italy, Jamaica, Japan, Kazakhstan, Latvia, Lithuania, Luxembourg, Malta, Mexico, Morocco, the Netherlands, New Zealand, Norway, Pakistan, the Philippines, Poland, Portugal, Romania, Russia, the Slovak Republic, Slovenia, South Africa, South Korea, Spain, Sri Lanka, Sweden, Switzerland, Thailand, Trinidad and Tobago, Tunisia, Turkey, Ukraine, the United Kingdom and Venezuela. Substitute payments received by the Fund for securities lent out by the Fund will not be qualified dividend income.

A dividend from the Fund will not be treated as qualified dividend income to the extent that: (i) the shareholder has not held the shares on which the dividend was paid for 61 days during the 121-day period that begins on the date that is 60 days before the date on which the shares become ex-dividend with respect to such dividend or the Fund fails to satisfy those holding period requirements with respect to the securities it holds that paid the dividends distributed to the shareholder (or, in the case of certain preferred stocks, the holding requirement of 91 days during the 181-day period beginning on the date that is 90 days before the date on which the stock becomes ex-dividend with respect to such dividend); (ii) the Fund or the shareholder is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to substantially similar or related property; or (iii) the shareholder elects to treat such dividend as investment income under Section 163(d)(4)(B) of the Internal Revenue Code. Dividends received by the Fund from a REIT or another RIC may be

treated as qualified dividend income only to the extent the dividend distributions are attributable to qualified dividend income received by such REIT or other RIC. In addition, the Tax Act permits a direct REIT shareholder to claim a 20% “qualified business income” deduction for ordinary REIT dividends, but does not permit a RIC paying dividends attributable to such income to pass through this special treatment to its shareholders. Unless future legislation or regulations provide for a pass-through, investors in such a RIC will treat such distributions as ordinary dividend income, as under prior law, whereas a direct REIT investor would benefit from the special treatment. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income. Distributions by the Fund of its net short-term capital gains will be taxable as ordinary income.

Corporate Dividends Received Deduction. Dividends paid by the Fund that are attributable to dividends received by the Fund from U.S. corporations may qualify for the U.S. federal dividends received deduction for corporations. A 46-day minimum holding period during the 90-day period that begins 45 days prior to ex-dividend date (or 91-day minimum holding period during the 180 period beginning 90 days prior to ex-dividend date for certain preference dividends) during which risk of loss may not be diminished is required for the applicable shares, at both the Fund and shareholder level, for a dividend to be eligible for the dividends received deduction. Restrictions may apply if indebtedness, including a short sale, is attributable to the investment.

Excess Inclusion Income. Under current law, the Fund serves to block unrelated business taxable income (“UBTI”) from being realized by its tax-exempt shareholders. Notwithstanding the foregoing, a tax-exempt shareholder could realize UBTI by virtue of its investment in the Fund if shares in the Fund constitute debt-financed property in the hands of the tax-exempt shareholder within the meaning of Section 514(b) of the Internal Revenue Code. Certain types of income received by the Fund from REITs, real estate mortgage investment conduits, taxable mortgage pools or other investments may cause the Fund to report some or all of its distributions as “excess inclusion income.” To Fund shareholders, such excess inclusion income may: (i) constitute taxable income, as UBTI for those shareholders who would otherwise be tax-exempt such as individual retirement accounts, 401(k) accounts, Keogh plans, pension plans and certain charitable entities; (ii) not be offset by otherwise allowable deductions for tax purposes; (iii) not be eligible for reduced U.S. withholding for non-U.S. shareholders even from tax treaty countries; and (iv) cause the Fund to be subject to tax if certain “disqualified organizations,” as defined by the Internal Revenue Code, are Fund shareholders. If a charitable remainder annuity trust or a charitable remainder unitrust (each as defined in Section 664 of the Internal Revenue Code) has UBTI for a taxable year, a 100% excise tax on the UBTI is imposed on the trust.

Non-U.S. Investments. Under Section 988 of the Internal Revenue Code, gains or losses attributable to fluctuations in exchange rates between the time the Fund accrues income or receivables or expenses or other liabilities denominated in a non-U.S. currency and the time the Fund actually collects such income or pays such liabilities are generally treated as ordinary income or ordinary loss. In general, gains (and losses) realized on debt instruments will be treated as Section 988 gain (or loss) to the extent attributable to changes in exchange rates between the U.S. dollar and the currencies in which the instruments are denominated. Similarly, gains or losses on non-U.S. currency, non-U.S. currency forward contracts and certain non-U.S. currency options or futures contracts denominated in non-U.S. currency, to the extent attributable to fluctuations in exchange rates between the acquisition and disposition dates, are also treated as ordinary income or loss unless the Fund were to elect otherwise.

The Fund may be subject to non-U.S. income taxes withheld at the source. The Fund, if permitted to do so, may elect to “pass through” to its investors the amount of non-U.S. income taxes paid by the Fund provided that the Fund held the security on the dividend settlement date and for at least 15 additional days immediately before and/or thereafter, with the result that each investor with respect to shares of the Fund held for a minimum 16-day holding period at the time of deemed distribution will (i) include in gross income, even though not actually received, the investor’s pro rata share of the Fund’s non-U.S. income taxes, and (ii) either deduct (in calculating U.S. taxable income, but only for investors who itemize their deductions on their personal tax returns) or credit (in calculating U.S. federal income tax) the investor’s pro rata share of the Fund’s non-U.S. income taxes. Withholding taxes on dividends on non-U.S. securities while such securities are lent out by the Fund are not eligible for non-U.S. tax credit pass through. Taxes not “passed through” for tax purposes will not be available to shareholders for foreign tax credit purposes. A non-U.S. person invested in the Fund in a year that the Fund elects to “pass through” its non-U.S. taxes may be treated as receiving additional dividend income subject to U.S. withholding tax. A non-U.S. tax credit may not exceed the investor’s U.S. federal income tax otherwise payable with respect to the investor’s non-U.S. source income. For this purpose, shareholders must treat as non-U.S. source gross income (i) their proportionate shares of non-U.S. taxes paid by the Fund and (ii) the portion of any dividend paid by the Fund that represents income derived from non-U.S. sources; the Fund’s gain from the sale of securities will generally be treated as U.S.-source income. Certain

limitations will be imposed to the extent to which the non-U.S. tax credit may be claimed. If your Fund shares are loaned pursuant to securities lending arrangements, you may lose the ability to use any non-U.S. tax credits passed through by a Fund or to treat Fund dividends (paid while the shares are held by the borrower) as qualified dividends. Regarding a short sale with respect to shares of a Fund, substitute payments made to the lender of such shares may not be deductible under certain circumstances. Consult your financial intermediary or tax advisor.

The Underlying Fund invests in non-U.S. positions and may be subject to non-U.S. income taxes and non-U.S. financial transactions taxes. The Underlying Fund may elect to “pass through” to its investors, including the Fund, the amount of non-U.S. income taxes paid by the Underlying Fund. The Fund will be eligible to elect to “pass through” such amounts to their stockholders and may do so, depending upon circumstances.

Passive Foreign Investment Companies. If the Fund purchases shares in PFICs, it may be subject to U.S. federal income tax on a portion of any “excess distribution” or gain from the disposition of such shares even if such income is distributed as a taxable dividend by the Fund to its shareholders. Additional charges in the nature of interest may be imposed on the Fund in respect of deferred taxes arising from such distributions or gains.

If the Fund were to invest in a PFIC and elect to treat the PFIC as a “qualified electing fund” under the Internal Revenue Code, in lieu of the foregoing requirements, the Fund might be required to include in income each year a portion of the ordinary earnings and net capital gains of the qualified electing fund, even if not distributed to the Fund, and such amounts would be subject to the 90% and excise tax distribution requirements described above. In order to make this election, the Fund would be required to obtain certain annual information from the PFICs in which it invests, which may be difficult or impossible to obtain. Currently proposed IRS regulations, if adopted, would treat such included amounts as nonqualifying RIC income to the Fund unless such amounts were also distributed to the Fund.

Alternatively, the Fund may make a mark-to-market election that would result in the Fund being treated as if it had sold and repurchased its PFIC stock at the end of each year. In such case, the Fund would report any such gains as ordinary income and would deduct any such losses as ordinary losses to the extent of previously recognized gains. The election must be made separately for each PFIC owned by the Fund and, once made, would be effective for all subsequent taxable years, unless revoked with the consent of the IRS. By making the election, the Fund could potentially ameliorate the adverse tax consequences with respect to its ownership of shares in a PFIC, but in any particular year may be required to recognize income in excess of the distributions it receives from PFICs and its proceeds from dispositions of PFIC stock. The Fund may have to distribute this “phantom” income and gain to satisfy the 90% distribution requirement and to avoid imposition of the 4% excise tax.

The Fund will make the appropriate tax elections, if possible, and take any additional steps that are necessary to mitigate the effects of these rules.

Reporting. If a shareholder recognizes a loss with respect to the Fund’s shares of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder must file with the IRS a disclosure statement on IRS Form 8886. Direct shareholders of portfolio securities are in many cases exempted from this reporting requirement, but under current guidance, shareholders of a RIC are not exempted. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer’s treatment of the loss is proper. Shareholders should consult their tax advisors to determine the applicability of these regulations in light of their individual circumstances.

Other Taxes. Dividends, distributions and redemption proceeds may also be subject to additional state, local and non-U.S. taxes depending on each shareholder’s particular situation.

Taxation of Non-U.S. Shareholders. Dividends paid by the Fund to non-U.S. shareholders are generally subject to withholding tax at a 30% rate or a reduced rate specified by an applicable income tax treaty to the extent derived from investment income and short-term capital gains. Dividends paid by the Fund from net tax-exempt income or long-term capital gains are generally not subject to such withholding tax. In order to obtain a reduced rate of withholding, a non-U.S. shareholder will be required to provide an IRS Form W-8BEN or IRS Form W-8BEN-E certifying its entitlement to benefits under a treaty. The withholding tax does not apply to regular dividends paid to a non-U.S. shareholder who provides an IRS Form W-8ECI, certifying that the dividends are effectively connected with the non-U.S. shareholder’s conduct of a trade or

business within the U.S. Instead, the effectively connected dividends will be subject to regular U.S. income tax as if the non-U.S. shareholder were a U.S. shareholder. A non-U.S. corporation receiving effectively connected dividends may also be subject to additional “branch profits tax” imposed at a rate of 30% (or lower treaty rate). A non-U.S. shareholder who fails to provide an IRS Form W-8BEN, IRS Form W-8BEN-E or other applicable form may be subject to backup withholding at the appropriate rate.

Properly-reported dividends are generally exempt from U.S. federal withholding tax where they (i) are paid in respect of the Fund’s “qualified net interest income” (generally, the Fund’s U.S. source interest income, other than certain contingent interest and interest from obligations of a corporation or partnership in which the Fund is at least a 10% shareholder or partner, reduced by expenses that are allocable to such income) or (ii) are paid in respect of the Fund’s “qualified short-term capital gains” (generally, the excess of the Fund’s net short-term capital gain over the Fund’s long-term capital loss for such taxable year). However, depending on its circumstances, the Fund may report all, some or none of its potentially eligible dividends as such qualified net interest income or as qualified short-term capital gains and/or treat such dividends, in whole or in part, as ineligible for this exemption from withholding. In order to qualify for this exemption from withholding, a non-U.S. shareholder will need to comply with applicable certification requirements relating to its non-U.S. status (including, in general, furnishing an IRS Form W-8BEN, IRS Form W-8BEN-E or substitute Form). In the case of shares held through an intermediary, the intermediary may withhold even if the Fund reports the payment as qualified net interest income or qualified short-term capital gain. Non-U.S. shareholders should contact their intermediaries with respect to the application of these rules to their accounts.

Distributions that the Fund reports as “short-term capital gain dividends” or “long-term capital gain dividends” will not be treated as such to a recipient foreign shareholder if the distribution is attributable to gain received from the sale or exchange of U.S. real property or an interest in a U.S. real property holding corporation and the Fund’s direct or indirect interests in U.S. real property exceeded certain levels. Instead, if the foreign shareholder has not owned more than 5% of the outstanding shares of the Fund at any time during the one year period ending on the date of distribution, such distributions will be subject to 30% withholding by the Fund and will be treated as ordinary dividends to the foreign shareholder; if the foreign shareholder owned more than 5% of the outstanding shares of the Fund at any time during the one year period ending on the date of the distribution, such distribution will be treated as real property gain subject to 21% withholding tax and could subject the foreign shareholder to U.S. filing requirements. Additionally, if the Fund’s direct or indirect interests in U.S. real property were to exceed certain levels, a foreign shareholder realizing gains upon redemption from the Fund could be subject to the 21% withholding tax and U.S. filing requirements unless more than 50% of the Fund’s shares were owned by U.S. persons at such time or unless the foreign person had not held more than 5% of the Fund’s outstanding shares throughout either such person’s holding period for the redeemed shares or, if shorter, the previous five years.

The rules laid out in the previous paragraph, other than the withholding rules, will apply notwithstanding the Fund’s participation in a wash sale transaction or its payment of a substitute dividend.

Distributions to certain foreign shareholders by a Fund at least 50% of the assets of which are “U.S. real property interests” (as defined in the Internal Revenue Code and U.S. Treasury regulations) at any time during the five-year period ending on the date of the distributions, to the extent the distributions are attributable to gains from sales or exchanges of U.S. real property interests (including shares in certain “U.S. real property holding corporations” such as certain REITs, although exceptions may apply if any class of stock of such a corporation is regularly traded on an established securities market and the Fund has held no more than 5% of such class of stock at any time during the five-year period ending on the date of the distributions), generally must be treated by such foreign shareholders as income effectively connected to a trade or business within the U.S., which is generally subject to tax at the graduated rates applicable to U.S. shareholders, except for distributions to foreign shareholders that held no more than 5% of any class of stock of the Fund at any time during the previous one-year period ending on the date of the distributions. Such distributions may be subject to U.S. withholding tax and may require a foreign shareholder to file a U.S. federal income tax return. In addition, sales or redemptions of shares held by certain foreign shareholders in such a Fund generally will be subject to U.S. withholding tax and generally will require the foreign shareholder to file a U.S. federal income tax return, although exceptions may apply if more than 50% of the value of the Fund’s shares are held by U.S. shareholders or the foreign shareholder selling or redeeming the shares has held no more than 5% of any class of stock of the Fund at any time during the five-year period ending on the date of the sale or redemption.

market and the Fund has held no more than 5% of such class of stock at any time during the five-year period ending on the date of the distribution) generally will cause the Fund to recognize a portion of any unrecognized gain in the U.S. real property interests equal to the product of (i) the excess of fair market value of such U.S. real property interests over the Fund’s adjusted bases in such interests and (ii) the greatest foreign ownership percentage of the Fund during the five-year period ending on the date of distribution.

Separately, a 30% withholding tax is currently imposed on U.S.-source dividends, interest and other income items, and will be imposed on proceeds from the sale, redemption or other disposition of property producing U.S.-source dividends and interest paid after December 31, 2018, to: (i) foreign financial institutions, including non-U.S. investment funds, unless they agree to collect and disclose to the IRS information regarding their direct and indirect U.S. account holders; and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to: (i) enter into agreements with the IRS that state that they will provide the IRS information, including the names, addresses and taxpayer identification numbers of direct and indirect U.S. account holders; comply with due diligence procedures with respect to the identification of U.S. accounts; report to the IRS certain information with respect to U.S. accounts maintained; agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information; and determine certain other information concerning their account holders, or (ii) in the event an intergovernmental agreement and implementing legislation are adopted, provide local revenue authorities with similar account holder information. Other foreign entities may need to report the name, address, and taxpayer identification number of each substantial U.S. owner or provide certifications of no substantial U.S. ownership unless certain exceptions apply.

Shares of the Fund held by a non-U.S. shareholder at death will be considered situated within the U.S. and subject to the U.S. estate tax.

The foregoing discussion is a summary of certain material U.S. federal income tax considerations only and is not intended as a substitute for careful tax planning. Purchasers of shares should consult their own tax advisors as to the tax consequences of investing in such shares, including consequences under state, local and non-U.S. tax laws. Finally, the foregoing discussion is based on applicable provisions of the Internal Revenue Code, regulations, judicial authority and administrative interpretations in effect on the date of this SAI. Changes in applicable authority could materially affect the conclusions discussed above, and such changes often occur.

BlackRock U.S. Registered Funds

Open-End Fund and iShares ETF¹ Proxy Voting Policy

Procedures Governing Delegation of Proxy Voting to Fund Adviser

July 1, 2017

The Boards of Trustees/Directors (“Directors”) of open-end funds advised by BlackRock Fund Advisors or BlackRock Advisors, LLC (“BlackRock”) (the “Funds”), have the responsibility for the oversight of voting proxies relating to portfolio securities of the Funds, and have determined that it is in the best interests of the Funds and their shareholders to delegate that responsibility to BlackRock as part of BlackRock’s authority to manage, acquire and dispose of account assets, all as contemplated by the Funds’ respective investment management agreements.

BlackRock has adopted guidelines and procedures (together and as from time to time amended, the “BlackRock Proxy Voting Guidelines”) governing proxy voting by accounts managed by BlackRock.

BlackRock will cast votes on behalf of each of the Funds on specific proxy issues in respect of securities held by each such Fund in accordance with the BlackRock Proxy Voting Guidelines.¹

BlackRock will report on an annual basis to the Directors on (1) all proxy votes that BlackRock has made on behalf of the Funds in the preceding year together with a certification from the Funds’ Chief Compliance Officer that all votes were in accordance with the BlackRock Proxy Voting Guidelines, and (2) any changes to the BlackRock Proxy Voting Guidelines that have not previously been reported.

iShares ESG 1-5 Year USD Corporate Bond ETF, iShares ESG USD Corporate Bond ETF, iShares MSCI ACWI Low Carbon Target ETF, iShares MSCI EAFE ESG Optimized ETF, iShares MSCI EM ESG Optimized ETF, iShares MSCI Global Impact ETF, iShares MSCI KLD 400 Social ETF, iShares MSCI Peru ETF, iShares MSCI USA ESG Optimized ETF, iShares MSCI USA ESG Select ETF and iShares MSCI USA Small-Cap ESG Optimized ETF have separate Fund Proxy Voting Policies.

INTRODUCTION TO BLACKROCK

BlackRock is the world’s preeminent asset management firm and a premier provider of global investment management, risk management and advisory services to institutional and individual clients around the world. BlackRock offers a wide range of investment strategies and product structures to meet clients’ needs, including individual and institutional separate accounts, mutual funds, closed-end funds, and other pooled investment vehicles and the industry-leading iShares exchange traded funds. Through BlackRock Solutions^®, we offer risk management, strategic advisory and enterprise investment system services to a broad base of clients.

PHILOSOPHY ON CORPORATE GOVERNANCE

BlackRock’s corporate governance program is focused on protecting and enhancing the economic value of the companies in which it invests on behalf of clients. We do this through engagement with boards and management of investee companies and, for those clients who have given us authority, through voting at shareholder meetings.

We believe that there are certain fundamental rights attached to share ownership. Companies and their boards should be accountable to shareholders and structured with appropriate checks and balances to ensure that they operate in shareholders’ interests. Effective voting rights are central to the rights of ownership and there should be one vote for one share. Shareholders should have the right to elect, remove and nominate directors, approve the appointment of the auditor and to amend the corporate charter or by-laws. Shareholders should be able to vote on matters that are material to the protection of their investment including but not limited to changes to the purpose of the business, dilution levels and pre-emptive rights, the distribution of income and the capital structure. In order to exercise these rights effectively, we believe shareholders have the right to sufficient and timely information to be able to take an informed view of the proposals, and of the performance of the company and management.

Our focus is on the board of directors, as the agent of shareholders, which should set the company’s strategic aims within a framework of prudent and effective controls which enables risk to be assessed and managed. The board should provide direction and leadership to the management and oversee management’s performance. Our starting position is to be supportive of boards in their oversight efforts on our behalf and we would generally expect to support the items of business they put to a vote at shareholder meetings. Votes cast against or withheld from resolutions proposed by the board are a signal that we are concerned that the directors or management have either not acted in the interests of shareholders or have not responded adequately to shareholder concerns regarding strategy or performance.

These principles set out our approach to engaging with companies, provide guidance on our position on corporate governance and outline how our views might be reflected in our voting decisions. Corporate governance practices vary internationally and our expectations in relation to individual companies are based on the legal and regulatory framework of each market. However, as noted above, we do believe that there are some overarching principles of corporate governance that apply globally. We assess voting matters on a case-by-case basis and in light of each company’s unique circumstances. We are interested to understand from the company’s reporting its approach to corporate governance, particularly where it is different from the usual market practice, and how it benefits shareholders.

BlackRock also believes that shareholders have responsibilities in relation to monitoring and providing feedback to companies, sometimes known as stewardship. These ownership responsibilities include, in our view, engaging with management or board members on corporate governance matters, voting proxies in the best long-term economic interests of shareholders and engaging with regulatory bodies to ensure a sound policy framework consistent with promoting long-term shareholder value creation. Institutional shareholders also have responsibilities to their clients to have appropriate resources and oversight structures. Our own approach to oversight in relation to our corporate governance activities is set out in the section below titled “BlackRock’s oversight of its corporate governance activities”.

CORPORATE GOVERNANCE, ENGAGEMENT AND VOTING

We recognize that accepted standards of corporate governance differ between markets but we believe that there are sufficient common threads globally to identify an overarching set of principles. The primary objective of our corporate governance activities is the protection and enhancement of the value of our clients’ investments in public corporations. Thus, these principles focus on practices and structures that we consider to be supportive of long-term value creation. We discuss below the principles under six key themes. In our regional and market-specific voting guidelines we explain how these

A-3

principles inform our voting decisions in relation to specific resolutions that may appear on the agenda of a shareholder meeting in the relevant market.

The six key themes are:

•	Boards and directors
•	Auditors and audit-related issues
•	Capital structure, mergers, asset sales and other special transactions
•	Remuneration and benefits
•	Social, ethical and environmental issues
•	General corporate governance matters

At a minimum we would expect companies to observe the accepted corporate governance standard in their domestic market or to explain why doing so is not in the interests of shareholders. Where company reporting and disclosure is inadequate or the approach taken is inconsistent with our view of what is in the best interests of shareholders, we typically will engage with the company and/or use our vote to encourage a change in practice. In making voting decisions, we take into account research from proxy advisors, other internal and external research, information published by the company or provided through engagement and the views of our equity portfolio managers.

BlackRock views engagement as an important activity; engagement provides BlackRock with the opportunity to improve our understanding of investee companies and their governance structures, so that our voting decisions may be better informed. Engagement also allows us to share our philosophy and approach to investment and corporate governance with companies to enhance their understanding of our objectives. There are a range of approaches we may take in engaging companies depending on the nature of the issue under consideration, the company and the market.

Boards and directors

The performance of the board is critical to the economic success of the company and to the protection of shareholders’ interests. Board members serve as agents of shareholders in overseeing the strategic direction and operation of the company. For this reason, BlackRock focuses on directors in many of its engagements and sees the election of directors as one of its most important responsibilities in the proxy voting context.

We expect the board of directors to promote and protect shareholder interests by:

•	establishing an appropriate corporate governance structure;
•	supporting and overseeing management in setting strategy;
•	ensuring the integrity of financial statements;
•	making decisions regarding mergers, acquisitions and disposals;
•	establishing appropriate executive compensation structures; and
•	addressing business issues including social, ethical and environmental issues when they have the potential to materially impact company reputation and performance.

There should be clear definitions of the role of the board, the sub-committees of the board and the senior management such that the responsibilities of each are well understood and accepted. Companies should report publicly the approach taken to governance (including in relation to board structure) and why this approach is in the interest of shareholders. We will engage with the appropriate directors where we have concerns about the performance of the board or the company, the broad strategy of the company or the performance of individual board members. Concerns about directors may include their role on the board of a different company where that board has performed poorly and failed to protect shareholder interests.

BlackRock believes that directors should stand for re-election on a regular basis. We assess directors nominated for election or re-election in the context of the composition of the board as a whole. There should be detailed disclosure of the relevant credentials of the individual directors in order that shareholders can assess the caliber of an individual nominee. We expect there to be a sufficient number of independent directors on the board to ensure the protection of the interests of all shareholders. Common impediments to independence may include but are not limited to:

•	current employment at the company or a subsidiary;

A-4

•	former employment within the past several years as an executive of the company;
•	providing substantial professional services to the company and/or members of the company’s management;
•	having had a substantial business relationship in the past three years;
•	having, or representing a shareholder with, a substantial shareholding in the company;
•	being an immediate family member of any of the aforementioned; and
•	interlocking directorships.

BlackRock believes that the operation of the board is enhanced when there is a clearly independent, senior non-executive director to lead it. Where the chairman is also the CEO or is otherwise not independent the company should have an independent lead director. The role of this director is to enhance the effectiveness of the independent members of the board through shaping the agenda, ensuring adequate information is provided to the board and encouraging independent participation in board deliberations. The lead independent board director should be available to shareholders if they have concerns that they wish to discuss.

To ensure that the board remains effective, regular reviews of board performance should be carried out and assessments made of gaps in skills or experience amongst the members. BlackRock believes it is beneficial for new directors to be brought onto the board periodically to refresh the group’s thinking and to ensure both continuity and adequate succession planning. In identifying potential candidates, boards should take into consideration the diversity of experience and expertise of the current directors and how that might be augmented by incoming directors. We believe that directors are in the best position to assess the optimal size for the board, but we would be concerned if a board seemed too small to have an appropriate balance of directors or too large to be effective.

There are matters for which the board has responsibility that may involve a conflict of interest for executives or for affiliated directors. BlackRock believes that shareholders’ interests are best served when the independent members of the board form a sub-committee to deal with such matters. In many markets, these sub-committees of the board specialize in audit, director nominations and compensation matters. An ad hoc committee might also be formed to decide on a special transaction, particularly one with a related party.

Auditors and audit-related issues

BlackRock recognizes the critical importance of financial statements which should provide a complete and accurate picture of a company’s financial condition. We will hold the members of the audit committee or equivalent responsible for overseeing the management of the audit function. We take particular note of cases involving significant financial restatements or ad hoc notifications of material financial weakness.

The integrity of financial statements depends on the auditor being free of any impediments to being an effective check on management. To that end, we believe it is important that auditors are, and are seen to be, independent. Where the audit firm provides services to the company in addition to the audit, the fees earned should be disclosed and explained. Audit committees should also have in place a procedure for assuring annually the independence of the auditor.

Capital structure, mergers, asset sales and other special transactions

The capital structure of a company is critical to its owners, the shareholders, as it impacts the value of their investment and the priority of their interest in the company relative to that of other equity or debt investors. Pre-emption rights are a key protection for shareholders against the dilution of their interests.

In assessing mergers, asset sales or other special transactions, BlackRock’s primary consideration is the long-term economic interests of shareholders. Boards proposing a transaction need to clearly explain the economic and strategic rationale behind it. We will review a proposed transaction to determine the degree to which it enhances long-term shareholder value. We would prefer that proposed transactions have the unanimous support of the board and have been negotiated at arm’s length. We may seek reassurance from the board that executive and/or board members’ financial interests in a given transaction have not affected their ability to place shareholders’ interests before their own. Where the transaction involves related parties, we would expect the recommendation to support it to come from the independent directors and would prefer only non-conflicted shareholders to vote on the proposal.

A-5

BlackRock believes that shareholders have a right to dispose of company shares in the open market without unnecessary restriction. In our view, corporate mechanisms designed to limit shareholders’ ability to sell their shares are contrary to basic property rights. Such mechanisms can serve to protect and entrench interests other than those of the shareholders. We believe that shareholders are broadly capable of making decisions in their own best interests. We would expect any so-called ‘shareholder rights plans’ being proposed by a board to be subject to shareholder approval on introduction and periodically thereafter for continuation.

Remuneration and benefits

BlackRock expects a company’s board of directors to put in place a compensation structure that incentivizes and rewards executives appropriately and is aligned with shareholder interests, particularly long-term shareholder returns. We would expect the compensation committee to take into account the specific circumstances of the company and the key individuals the board is trying to incentivize. We encourage companies to ensure that their compensation packages incorporate appropriate and challenging performance conditions consistent with corporate strategy and market practice. We use third party research, in addition to our own analysis, to evaluate existing and proposed compensation structures. We hold members of the compensation committee or equivalent accountable for poor compensation practices or structures.

BlackRock believes that there should be a clear link between variable pay and company performance as reflected in returns to shareholders. We are not supportive of one-off or special bonuses unrelated to company or individual performance. We support incentive plans that pay out rewards earned over multiple and extended time periods. We believe consideration should be given to building claw back provisions into incentive plans such that executives would be required to repay rewards where they were not justified by actual performance. Compensation committees should guard against contractual arrangements that would entitle executives to material compensation for early termination of their contract. Finally, pension contributions should be reasonable in light of market practice.

Outside directors should be compensated in a manner that does not risk compromising their independence or aligning their interests too closely with those of the management, whom they are charged with overseeing.

Social, ethical, and environmental issues

Our fiduciary duty to clients is to protect and enhance their economic interest in the companies in which we invest on their behalf. It is within this context that we undertake our corporate governance activities. We believe that well-managed companies will deal effectively with the social, ethical and environmental (“SEE”) aspects of their businesses.

BlackRock expects companies to identify and report on the material, business-specific SEE risks and opportunities and to explain how these are managed. This explanation should make clear how the approach taken by the company best serves the interests of shareholders and protects and enhances the long-term economic value of the company. The key performance indicators in relation to SEE matters should also be disclosed and performance against them discussed, along with any peer group benchmarking and verification processes in place. This helps shareholders assess how well management is dealing with the SEE aspects of the business. Any global standards adopted should also be disclosed and discussed in this context.

We may vote against the election of directors where we have concerns that a company might not be dealing with SEE issues appropriately. Sometimes we may reflect such concerns by supporting a shareholder proposal on the issue, where there seems to be either a significant potential threat or realized harm to shareholders’ interests caused by poor management of SEE matters. In deciding our course of action, we will assess whether the company has already taken sufficient steps to address the concern and whether there is a clear and material economic disadvantage to the company if the issue is not addressed.

More commonly, given that these are often not voting issues, we will engage directly with the board or management. The trigger for engagement on a particular SEE concern is our assessment that there is potential for material economic ramifications for shareholders.

We do not see it as our role to make social, ethical or political judgments on behalf of clients. We expect investee companies to comply, at a minimum, with the laws and regulations of the jurisdictions in which they operate. They should explain how they manage situations where such laws or regulations are contradictory or ambiguous.

A-6

General corporate governance matters

BlackRock believes that shareholders have a right to timely and detailed information on the financial performance and viability of the companies in which they invest. In addition, companies should also publish information on the governance structures in place and the rights of shareholders to influence these. The reporting and disclosure provided by companies helps shareholders assess whether the economic interests of shareholders have been protected and the quality of the board’s oversight of management. BlackRock believes shareholders should have the right to vote on key corporate governance matters, including on changes to governance mechanisms, to submit proposals to the shareholders’ meeting and to call special meetings of shareholders.

BLACKROCK’S OVERSIGHT OF ITS CORPORATE GOVERNANCE ACTIVITIES

Oversight

BlackRock holds itself to a very high standard in its corporate governance activities, including in relation to executing proxy votes. This function is executed by a team of dedicated BlackRock employees without sales responsibilities (the “Corporate Governance Group”), and which is considered an investment function. BlackRock maintains three regional oversight committees (“Corporate Governance Committees”) for the Americas, Europe, the Middle East and Africa (EMEA) and Asia-Pacific, consisting of senior BlackRock investment professionals. All of the regional Corporate Governance Committees report to a Global Corporate Governance Oversight Committee, which is a risk-focused committee composed of senior representatives of the active and index equity investment businesses, the Deputy General Counsel, the Global Executive Committee member to whom the Corporate Governance Group reports and the head of the Corporate Governance Group. The Corporate Governance Committees review and approve amendments to their respective proxy voting guidelines (“Guidelines”) and grant authority to the Global Head of Corporate Governance (“Global Head”), a dedicated BlackRock employee without sales responsibilities, to vote in accordance with the Guidelines. The Global Head leads the Corporate Governance Group to carry out engagement, voting and vote operations in a manner consistent with the relevant Corporate Governance Committee’s mandate. The Corporate Governance Group engages companies in conjunction with the portfolio managers in discussions of significant governance issues, conducts research on corporate governance issues and participates in industry discussions to keep abreast of the field of corporate governance. The Corporate Governance Group, or vendors overseen by the Corporate Governance Group, also monitor upcoming proxy votes, execute proxy votes and maintain records of votes cast. The Corporate Governance Group may refer complicated or particularly controversial matters or discussions to the appropriate investors and/or regional Corporate Governance Committees for their review, discussion and guidance prior to making a voting decision.

BlackRock’s Equity Policy Oversight Committee (EPOC) is informed of certain aspects of the work of the Global Corporate Governance Oversight Committee and the Corporate Governance Group.

Vote execution

BlackRock carefully considers proxies submitted to funds and other fiduciary accounts (“Funds”) for which it has voting authority. BlackRock votes (or refrains from voting) proxies for each Fund for which it has voting authority based on BlackRock’s evaluation of the best long-term economic interests of shareholders, in the exercise of its independent business judgment, and without regard to the relationship of the issuer of the proxy (or any dissident shareholder) to the Fund, the Fund’s affiliates (if any), BlackRock or BlackRock’s affiliates.

When exercising voting rights, BlackRock will normally vote on specific proxy issues in accordance with its Guidelines for the relevant market. The Guidelines are reviewed regularly and are amended consistent with changes in the local market practice, as developments in corporate governance occur, or as otherwise deemed advisable by BlackRock’s Corporate Governance Committees. The Corporate Governance Committees may, in the exercise of their business judgment, conclude that the Guidelines do not cover the specific matter upon which a proxy vote is requested or that an exception to the Guidelines would be in the best long-term economic interests of BlackRock’s clients.

In the uncommon circumstance of there being a vote with respect to fixed-income securities or the securities of privately held issuers the decision generally will be made by a Fund’s portfolio managers and/or the Corporate Governance Group based on their assessment of the particular transactions or other matters at issue.

In certain markets, proxy voting involves logistical issues which can affect BlackRock’s ability to vote such proxies, as well as the desirability of voting such proxies. These issues include but are not limited to: (i) untimely notice of shareholder

A-7

meetings; (ii) restrictions on a foreigner’s ability to exercise votes; (iii) requirements to vote proxies in person; (iv) “share- blocking” (requirements that investors who exercise their voting rights surrender the right to dispose of their holdings for some specified period in proximity to the shareholder meeting); (v) potential difficulties in translating the proxy; and (vi) requirements to provide local agents with unrestricted powers of attorney to facilitate voting instructions. We are not supportive of impediments to the exercise of voting rights such as shareblocking or overly burdensome administrative requirements.

As a consequence, BlackRock votes proxies in these markets only on a “best-efforts” basis. In addition, the Corporate Governance Committees may determine that it is generally in the best interests of BlackRock clients not to vote proxies of companies in certain countries if the committee determines that the costs (including but not limited to opportunity costs associated with shareblocking constraints) associated with exercising a vote are expected to outweigh the benefit the client would derive by voting on the issuer’s proposal.

While it is expected that BlackRock, as a fiduciary, will generally seek to vote proxies over which BlackRock exercises voting authority in a uniform manner for all BlackRock clients, the relevant Corporate Governance Committee, in conjunction with the portfolio manager of an account, may determine that the specific circumstances of such an account require that such account’s proxies be voted differently due to such account’s investment objective or other factors that differentiate it from other accounts. In addition, BlackRock believes portfolio managers may from time to time legitimately reach differing but equally valid views, as fiduciaries for their funds and the client assets in those Funds, on how best to maximize economic value in respect of a particular investment. Accordingly, portfolio managers retain full discretion to vote the shares in the Funds they manage based on their analysis of the economic impact of a particular ballot item.

Conflicts management

BlackRock maintains policies and procedures that are designed to prevent undue influence on BlackRock’s proxy voting activity that might stem from any relationship between the issuer of a proxy (or any dissident shareholder) and BlackRock, BlackRock’s affiliates, a Fund or a Fund’s affiliates. Some of the steps BlackRock has taken to prevent conflicts include, but are not limited to:

•	BlackRock has adopted a proxy voting oversight structure whereby the Corporate Governance Committees oversee the voting decisions and other activities of the Corporate Governance Group, and particularly its activities with respect to voting in the relevant region of each Corporate Governance Committee’s jurisdiction.
•	The Corporate Governance Committees have adopted Guidelines for each region, which set forth the firm’s views with respect to certain corporate governance and other issues that typically arise in the proxy voting context. The Corporate Governance Committees receive periodic reports regarding the specific votes cast by the Corporate Governance Group and regular updates on material process issues, procedural changes and other matters of concern to the Corporate Governance Committees.
•	BlackRock’s Global Corporate Governance Oversight Committee oversees the Global Head, the Corporate Governance Group and the Corporate Governance Committees. The Global Corporate Governance Oversight Committee conducts a review, at least annually, of the proxy voting process to ensure compliance with BlackRock’s risk policies and procedures.
•	BlackRock maintains a reporting structure that separates the Global Head and Corporate Governance Group from employees with sales responsibilities. In addition, BlackRock maintains procedures intended to ensure that all engagements with corporate issuers or dissident shareholders are managed consistently and without regard to BlackRock’s relationship with the issuer of the proxy or dissident shareholder. Within the normal course of business, the Global Head or Corporate Governance Group may engage directly with BlackRock clients, and with employees with sales responsibilities, in discussions regarding general corporate governance policy matters, and to otherwise ensure that proxy-related client service levels are met. The Global Head or Corporate Governance Group does not discuss any specific voting matter with a client prior to the disclosure of the vote decision to all applicable clients after the shareholder meeting has taken place, except if the client is acting in the capacity as issuer of the proxy or dissident shareholder and is engaging through the established procedures independent of the client relationship.
•	In certain instances, BlackRock may determine to engage an independent fiduciary to vote proxies as a further safeguard to avoid potential conflicts of interest or as otherwise required by applicable law. The independent fiduciary may either vote such proxies or provide BlackRock with instructions as to how to vote such proxies. In the latter case, BlackRock votes the proxy in accordance with the independent fiduciary’s determination. Use of an independent fiduciary has been

A-8

adopted for voting the proxies related to any company that is affiliated with BlackRock or any company that includes BlackRock employees on its board of directors.

With regard to the relationship between securities lending and proxy voting, BlackRock’s approach is driven by our clients’ economic interests. The evaluation of the economic desirability of recalling loans involves balancing the revenue producing value of loans against the likely economic value of casting votes. Based on our evaluation of this relationship, we believe that generally the likely economic value of casting most votes is less than the securities lending income, either because the votes will not have significant economic consequences or because the outcome of the vote would not be affected by BlackRock recalling loaned securities in order to ensure they are voted. Periodically, BlackRock analyzes the process and benefits of voting proxies for securities on loan, and will consider whether any modification of its proxy voting policies or procedures is necessary in light of future conditions. In addition, BlackRock may in its discretion determine that the value of voting outweighs the cost of recalling shares, and thus recall shares to vote in that instance.

Voting guidelines

The issue-specific voting Guidelines published for each region/country in which we vote are intended to summarize BlackRock’s general philosophy and approach to issues that may commonly arise in the proxy voting context in each market where we invest. These Guidelines are not intended to be exhaustive. BlackRock applies the Guidelines on a case-by-case basis, in the context of the individual circumstances of each company and the specific issue under review.

As such, these Guidelines do not provide a guide to how BlackRock will vote in every instance. Rather, they share our view about corporate governance issues generally, and provide insight into how we typically approach issues that commonly arise on corporate ballots.

Reporting

We report our proxy voting activity directly to clients and publicly as required. In addition, we publish for clients a more detailed discussion of our corporate governance activities, including engagement with companies and with other relevant parties.

Appendix B - Regular Holidays and Redemptions

Regular Holidays. For every occurrence of one or more intervening holidays in the applicable non-U.S. market that are not holidays observed in the U.S. equity market, the redemption settlement cycle may be extended by the number of such intervening holidays. In addition to holidays, other unforeseeable closings in a non-U.S. market due to emergencies and delivery cycles for transferring securities to redeeming investors may also prevent the Trust from delivering securities within the normal settlement period.

The securities delivery cycles currently practicable for transferring portfolio securities to redeeming investors, coupled with non-U.S. market holiday schedules, will require a delivery process longer than seven calendar days, in certain circumstances. The holidays applicable to the Fund during such periods are listed below, as are instances where more than seven days will be needed to deliver redemption proceeds. Although certain holidays may occur on different dates in subsequent years, the number of days required to deliver redemption proceeds in any given year is not expected to exceed the maximum number of days listed below for the Fund. The proclamation of new holidays, the treatment by market participants of certain days as “informal holidays” (e.g., days on which no or limited securities transactions occur, as a result of substantially shortened trading hours), the elimination of existing holidays, or changes in local securities delivery practices, could affect the information set forth herein in the future.

In calendar year 2018 (the only year for which holidays are known at the time of filing of this SAI), the dates of regular holidays affecting the relevant securities markets in which the Fund invests are as follows (please note that these holiday schedules are subject to potential changes in the relevant securities markets):

2018

Japan
January 1	April 30	October 8
January 2	May 3	November 23
January 3	May 4	December 24
January 8	July 16	December 31
February 12	September 17
March 21	September 24

Redemptions.The longest redemption cycle for the Fund is a function of the longest redemption cycle among the countries and regions whose securities comprise the Fund. In the calendar year 2018 (the only year for which holidays are known at the time of this SAI filing), the dates of regular holidays affecting the following securities markets present the worst-case redemption cycles* for the Fund as follows:

2018
Country	Trade Date	Settlement Date	Number of Days to Settle
Japan	04/27/18	05/07/18	10

*	These worst-case redemption cycles are based on information regarding regular holidays, which may be out of date. Based on changes in holidays, longer (worse) redemption cycles are possible.

A discussion of exchange listing and trading matters associated with an investment in each Fund is contained in the Shareholder Information section of each Fund's Prospectus. The discussion below supplements, and should be read in conjunction with, that section of the applicable Prospectus.

Shares of each Fund are listed for trading, and trade throughout the day, on the Listing Exchange and in other secondary markets. Shares of the Funds may also be listed on certain non-U.S. exchanges. There can be no assurance that the requirements of the Listing Exchange necessary to maintain the listing of shares of any Fund will continue to be met. The Listing Exchange may, but is not required to, remove the shares of a Fund from listing if, among other things: (i) following the initial 12-month period beginning upon the commencement of trading of Fund shares, there are fewer than 50 record and/or beneficial owners of shares of the Fund for 30 or more consecutive trading days, (ii) the value of the Underlying Index on which a Fund is based is no longer calculated or available, or (iii) any other event shall occur or condition shall exist that, in the opinion of the Listing Exchange, makes further dealings on the Listing Exchange inadvisable. The Listing Exchange will also remove shares of a Fund from listing and trading upon termination of the Fund or in the event a Fund does not comply with the continuous listing standards of the Listing Exchange, as described in the Fund’s Prospectus.

As in the case of other publicly-traded securities, when you buy or sell shares of a Fund through a broker, you may incur a brokerage commission determined by that broker, as well as other charges.

In order to provide additional information regarding the indicative value of shares of the Funds, the Listing Exchange or a market data vendor disseminates information every 15 seconds through the facilities of the Consolidated Tape Association, or through other widely disseminated means, an updated indicative optimized portfolio value (“IOPV”) for the Funds as calculated by an information provider or market data vendor. The Trust is not involved in or responsible for any aspect of the calculation or dissemination of the IOPV and makes no representation or warranty as to the accuracy of the IOPV.

An IOPV has a fixed-income securities component and a cash component. The fixed income securities values included in an IOPV are the values of the Deposit Securities for a Fund. While the IOPV reflects the current value of the Deposit Securities required to be deposited in connection with the purchase of a Creation Unit, it does not necessarily reflect the precise composition of the current portfolio of securities held by the Funds at a particular point in time because the current portfolio of the Funds may include securities that are not a part of the current Deposit Securities. Therefore, a Fund’s IOPV disseminated during the Listing Exchange trading hours should not be viewed as a real-time update of the Fund’s NAV, which is calculated only once a day.

The cash component included in an IOPV consists of estimated accrued interest, dividends and other income, less expenses. If applicable, each IOPV also reflects changes in currency exchange rates between the U.S. dollar and the applicable currency.

The Trust reserves the right to adjust the share prices of the Funds in the future to maintain convenient trading ranges for investors. Any adjustments would be accomplished through stock splits or reverse stock splits, which would have no effect on the net assets of the Funds or an investor's equity interest in the Funds.

Investment Strategies and Risks

Each Fund seeks to achieve its objective by investing primarily in both fixed-income securities issued by issuers that comprise its relevant Underlying Index and through transactions that provide substantially similar exposure to securities in the Underlying Index. Each Fund operates as an index fund and is not actively managed. Adverse performance of a security in a Fund’s portfolio will ordinarily not result in the elimination of the security from the Fund’s portfolio.

Each Fund engages in representative sampling, which is investing in a sample of securities selected by BFA to have a collective investment profile similar to that of the Fund's Underlying Index. Securities selected have aggregate investment characteristics (based on market capitalization and industry weightings), fundamental characteristics (such as yield, credit rating, maturity and duration) and liquidity measures similar to those of the Underlying Index. A fund that uses representative sampling generally does not hold all of the securities that are in its underlying index.

Although the Funds do not seek leveraged returns, certain instruments used by the Funds may have a leveraging effect as described below.

Each Fund generally will invest at least 90% of its assets in the component securities of its Underlying Index, except during the last months of the Fund’s operations, as described below, and may invest up to 10% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates (“BlackRock Cash Funds”), as well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. From time to time when conditions warrant, however, each Fund may invest at least 80% of its assets in the component securities of its Underlying Index and may invest up to 20% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of BlackRock Cash Funds, as well as in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. Additionally, under normal circumstances, each Fund will invest at least 80% of the value of its net assets, plus the amount of any borrowings for investment purposes, in investments the income of which is free from federal income tax, including the federal alternative minimum tax (“AMT”). This policy is a fundamental policy of each Fund and may not be changed without a vote of a majority of the Fund’s outstanding voting securities, as defined in the 1940 Act. Each Fund may invest the remainder of its assets in securities not included in its Underlying Index, but which BFA believes will help the Fund track its Underlying Index, except during the last months of the Fund's operations as described below. Each Fund also may invest its other assets in cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

In addition, each Fund may invest any cash assets in one or more affiliated money market funds. In the last months of each Fund's operation, as the bonds held by the Fund mature, the proceeds will not be reinvested in bonds, but instead will be held in cash and cash equivalents which will facilitate liquidation at the Fund's termination date, including, without limitation, AMT-free tax-exempt municipal notes (tax anticipation notes, revenue anticipation notes, tax and revenue anticipation notes, grant anticipation notes and bond anticipation notes); variable rate demand notes and obligations; tender option bonds; and municipal commercial paper. These cash equivalents may not be included in the Underlying Index. On or about September 1 of the relevant year, each Fund intends to wind up and terminate. Upon its termination, each Fund will distribute substantially all of its net assets, after making appropriate provision for any liabilities of the Fund, to then-current shareholders.

Bonds. Each Fund invests a substantial portion of its assets in U.S. dollar-denominated bonds. A bond is an interest-bearing security issued by a U.S. or non-U.S. company, or U.S. or non-U.S. governmental unit. The issuer of a bond has a contractual obligation to pay interest at a stated rate on specific dates and to repay principal (the bond’s face value) periodically or on a specified maturity date. Bonds generally are used by corporations and governments to borrow money from investors.

An issuer may have the right to redeem or “call” a bond before maturity, in which case a Fund may have to reinvest the proceeds at lower market rates. Similarly, a Fund may have to reinvest interest income or payments received when bonds mature, sometimes at lower market rates. Most bonds bear interest income at a “coupon” rate that is fixed for the life of the bond. The value of a fixed-rate bond usually rises when market interest rates fall, and falls when market interest rates rise. Accordingly, a fixed-rate bond’s yield (income as a percent of the bond’s current value) may differ from its coupon rate as its value rises or falls. When an investor purchases a fixed-rate bond at a price that is greater than its face value, the investor is purchasing the bond at a premium. Conversely, when an investor purchases a fixed-rate bond at a price that is less than its face value, the investor is purchasing the bond at a discount. Fixed-rate bonds that are purchased at a discount pay less current income than securities with comparable yields that are purchased at face value, with the result that prices for such fixed-rate securities can be more volatile than prices for such securities that are purchased at face value. Other types of bonds bear interest at an interest rate that is adjusted periodically. Interest rates on “floating rate” or “variable rate” bonds may be higher or lower than current market rates for fixed-rate bonds of comparable quality with similar final maturities. Because of their adjustable interest rates, the value of “floating rate” or “variable rate” bonds fluctuates much less in response to market interest rate movements than the value of fixed-rate bonds, but their value may decline if their interest rates do not rise as much, or as quickly, as interest rates in general. Each Fund may treat some of these bonds as having a shorter maturity for purposes of calculating the weighted average maturity of its investment portfolio. Generally, prices of higher quality issues tend to fluctuate less with changes in market interest rates than prices of lower quality issues and prices of longer maturity issues tend to fluctuate more than prices of shorter maturity issues. Bonds may be senior or subordinated obligations. Senior obligations generally have the first claim on a corporation’s earnings and assets and, in the event of liquidation, are paid before subordinated obligations. Bonds may be unsecured (backed only by the issuer’s general creditworthiness) or secured (backed by specified collateral).

The purchase of securities while borrowings are outstanding may have the effect of leveraging a Fund. The incurrence of leverage increases a Fund’s exposure to risk, and borrowed funds are subject to interest costs that will reduce net income. Purchasing securities while borrowings are outstanding creates special risks, such as the potential for greater volatility in the net asset value of Fund shares and in the yield on a Fund’s portfolio. In addition, the interest expenses from borrowings may exceed the income generated by a Fund’s portfolio and, therefore, the amount available (if any) for distribution to shareholders as dividends may be reduced. BFA may determine to maintain outstanding borrowings if it expects that the benefits to a Fund’s shareholders will outweigh the current reduced return.

Certain types of borrowings by a Fund must be made from a bank or may result in a Fund being subject to covenants in credit agreements relating to asset coverage, portfolio composition requirements and other matters. It is not anticipated that observance of such covenants would impede BFA’s management of a Fund’s portfolio in accordance with a Fund’s investment objectives and policies. However, a breach of any such covenants not cured within the specified cure period may result in acceleration of outstanding indebtedness and require a Fund to dispose of portfolio investments at a time when it may be disadvantageous to do so.

Diversification Status. Each Fund is classified as a diversified fund under the 1940 Act. This means that each Fund may not purchase securities of an issuer (other than (i) obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities and (ii) securities of other investment companies) if, with respect to 75% of its total assets, (a) more than 5% of the fund’s total assets would be invested in securities of that issuer or (b) the fund would hold more than 10% of the outstanding voting securities of that issuer. With respect to the remaining 25% of its total assets, the fund may invest more than 5% of its assets in one issuer. Under the 1940 Act, the fund cannot change its classification from diversified to non-diversified without shareholder approval.

Each Fund intends to maintain the required level of diversification and otherwise conduct its operations so as to qualify as a regulated investment company (“RIC”) for purposes of the U.S. Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), and to relieve the Fund of any liability for U.S. federal income tax to the extent that its earnings are distributed to shareholders, provided that the Fund satisfies a minimum distribution requirement. Compliance with the diversification requirements of the Internal Revenue Code may limit the investment flexibility of the Funds and may make it less likely that the Funds will meet their respective investment objectives.

Illiquid Securities. Each Fund may invest up to an aggregate amount of 15% of its net assets in illiquid securities (calculated at the time of investment). Illiquid securities may include securities subject to contractual or other restrictions on resale and other instruments that lack readily available markets, as determined in accordance with SEC staff guidance. The liquidity of a security relates to the ability to readily dispose of the security and the price to be obtained upon disposition of the security, which may be lower than the price that would be obtained for a comparable, more liquid security. Illiquid securities may trade at a discount to comparable, more liquid securities and a Fund may not be able to dispose of illiquid securities in a timely fashion or at their expected prices.

Lending Portfolio Securities. Each Fund may lend portfolio securities to certain borrowers that BFA determines to be creditworthy, including borrowers affiliated with BFA. The borrowers provide collateral that is maintained in an amount at least equal to the current market value of the securities loaned. No securities loan shall be made on behalf of a Fund if, as a result, the aggregate value of all securities loaned by the particular Fund exceeds one-third of the value of such Fund's total assets (including the value of the collateral received). A Fund may terminate a loan at any time and obtain the return of the securities loaned. Each Fund receives, by way of substitute payment, the value of any interest or cash or non-cash distributions paid on the loaned securities that it would have received if the securities were not on loan. Substitute payments received on tax-exempt securities loaned out will not be tax-exempt income.

With respect to loans that are collateralized by cash, the borrower may be entitled to receive a fee based on the amount of cash collateral. The Funds are typically compensated by the difference between the amount earned on the reinvestment of cash collateral and the fee paid to the borrower. In the case of collateral other than cash, a Fund is typically compensated by a fee paid by the borrower equal to a percentage of the market value of the loaned securities. Any cash collateral may be reinvested in certain short-term instruments either directly on behalf of each lending Fund or through one or more joint accounts or money market funds, including those affiliated with BFA; such investments are subject to investment risk.

Each Fund conducts its securities lending pursuant to an exemptive order from the SEC permitting it to lend portfolio securities to borrowers affiliated with the Fund and to retain an affiliate of the Fund to act as securities lending agent. To the extent that a Fund engages in securities lending, BlackRock Institutional Trust Company, N.A. (“BTC”) acts as securities lending agent for the Fund, subject to the overall supervision of BFA. BTC administers the lending program in accordance with guidelines approved by the Trust's Board of Trustees (the “Board,” the trustees of which are the “Trustees”).

Securities lending involves exposure to certain risks, including operational risk (i.e., the risk of losses resulting from problems in the settlement and accounting process), “gap” risk (i.e., the risk of a mismatch between the return on cash collateral reinvestments and the fees a Fund has agreed to pay a borrower), and credit, legal, counterparty and market risk. If a securities lending counterparty were to default, a Fund would be subject to the risk of a possible delay in receiving collateral or in recovering the loaned securities, or to a possible loss of rights in the collateral. In the event a borrower does not return a Fund’s securities as agreed, the Fund may experience losses if the proceeds received from liquidating the collateral do not at least equal the value of the loaned security at the time the collateral is liquidated, plus the transaction costs incurred in purchasing replacement securities. This event could trigger adverse tax consequences for a Fund. A Fund could lose money if its short-term investment of the collateral declines in value over the period of the loan. Substitute payments for dividends received by a Fund for securities loaned out by the Fund will not be considered qualified dividend income. BTC will take into

account the tax effects on shareholders caused by this difference in connection with a Fund’s securities lending program. Substitute payments received on tax-exempt securities loaned out will not be tax-exempt income.

Ratings. An investment-grade rating generally means the security or issuer is rated investment-grade by one or more of Moody’s Investors Service, Inc. (“Moody’s”), S&P Global Ratings, Fitch Ratings, Inc. (“Fitch”), or another credit rating agency designated as a nationally-recognized statistical rating organization (“NRSRO”) by the SEC, or is unrated but considered to be of equivalent quality by BFA. Generally, bonds rated Baa3 or above by Moody’s or BBB- or above by S&P Global Ratings and Fitch are considered “investment-grade” securities, bonds rated Baa are considered medium grade obligations subject to moderate credit risk and may possess certain speculative characteristics, while bonds rated BBB are regarded as having adequate capacity to meet financial commitments.

Subsequent to purchase by a Fund, a rated security may cease to be rated or its rating may be reduced below an investment-grade rating. Bonds rated lower than Baa3 by Moody’s or BBB- by S&P Global Ratings or Fitch are generally considered below investment-grade quality and are obligations of issuers that are generally considered predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal according to the terms of the obligation and, therefore, carry greater investment risk, including the possibility of issuer default and bankruptcy and increased market price volatility. Such lower-rated securities are commonly referred to as “junk bonds” and are subject to a substantial degree of credit risk. Please see Appendix B of this SAI for a description of each rating category of Moody's, S&P Global Ratings and Fitch.

Regulation Regarding Derivatives. The Commodity Futures Trading Commission (“CFTC”) subjects advisers to registered investment companies to regulation by the CFTC if a fund that is advised by the adviser either (i) invests, directly or indirectly, more than a prescribed level of its liquidation value in CFTC-regulated futures, options and swaps (“CFTC Derivatives”), or (ii) markets itself as providing investment exposure to such instruments. The CFTC also subjects advisers to registered investment companies to regulation by the CFTC if the registered investment company invests in one or more commodity pools. To the extent a Fund uses CFTC Derivatives, it intends to do so below such prescribed levels and intends not to market itself as a “commodity pool” or a vehicle for trading such instruments.

BFA has claimed an exclusion from the definition of the term “commodity pool operator” under the Commodity Exchange Act (“CEA”) pursuant to Rule 4.5 under the CEA with respect to the Funds. BFA is not, therefore, subject to registration or regulation as a “commodity pool operator” under the CEA with respect to the Funds.

Derivative contracts, including, without limitation, swaps, currency forwards, and non-deliverable forwards, are subject to regulation under the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”) in the U.S. and under comparable regimes in Europe, Asia and other non-U.S. jurisdictions. Swaps, non-deliverable forwards and certain other derivatives traded in the OTC market are subject to variation margin requirements, and initial margining requirements will be phased in through 2020. Implementation of the margining and other provisions of the Dodd-Frank Act regarding clearing, mandatory trading, reporting and documentation of swaps and other derivatives have impacted and may continue to impact the costs to a Fund of trading these instruments and, as a result, may affect returns to investors in a Fund.

As a result of regulatory requirements under the 1940 Act, a Fund is required to maintain an amount of liquid assets, accrued on a daily basis, having an aggregate value at least equal to the value of a Fund’s obligations under the applicable derivatives contract. To the extent that derivatives contracts are settled on a physical basis, a Fund will generally be required to maintain an amount of liquid assets equal to the notional value of the contract. On the other hand, in connection with derivatives contracts that are performed on a net basis, a Fund will generally be required to maintain liquid assets, accrued daily, equal only to the accrued excess, if any, of a Fund’s obligations over those of its counterparty under the contract. Accordingly, reliance by a Fund on physically-settled derivatives contracts may adversely impact investors by requiring a Fund to set aside a greater amount of liquid assets than would generally be required if a Fund were relying on cash-settled derivatives contracts.

Repurchase Agreements. A repurchase agreement is an instrument under which the purchaser (i.e., a Fund) acquires the security and the seller agrees, at the time of the sale, to repurchase the security at a mutually agreed-upon time and price, thereby determining the yield during the purchaser’s holding period. Repurchase agreements may be construed to be collateralized loans by the purchaser to the seller secured by the securities transferred to the purchaser. If a repurchase agreement is construed to be a collateralized loan, the underlying securities will not be considered to be owned by a Fund but only to constitute collateral for the seller’s obligation to pay the repurchase price, and, in the event of a default by the seller, the Fund may suffer time delays and incur costs or losses in connection with the disposition of the collateral.

Repurchase agreements pose certain risks for a Fund that utilizes them. Such risks are not unique to the Funds, but are inherent in repurchase agreements. The Funds seek to minimize such risks, but because of the inherent legal uncertainties involved in repurchase agreements, such risks cannot be eliminated. Lower quality collateral and collateral with a longer maturity may be subject to greater price fluctuations than higher quality collateral and collateral with a shorter maturity. If the repurchase agreement counterparty were to default, lower quality collateral may be more difficult to liquidate than higher quality collateral. Should the counterparty default and the amount of collateral not be sufficient to cover the counterparty’s repurchase obligation, a Fund would likely retain the status of an unsecured creditor of the counterparty (i.e., the position a Fund would normally be in if it were to hold, pursuant to its investment policies, other unsecured debt securities of the defaulting counterparty) with respect to the amount of the shortfall. As an unsecured creditor, a Fund would be at risk of losing some or all of the principal and income involved in the transaction.

Reverse Repurchase Agreements. Reverse repurchase agreements involve the sale of securities with an agreement to repurchase the securities at an agreed-upon price, date and interest payment and have the characteristics of borrowing. Generally, the effect of such transactions is that a Fund can recover all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement, while in many cases the Fund is able to keep some of the interest income associated with those securities. Such transactions are advantageous only if a Fund has an opportunity to earn a rate of interest on the cash derived from these transactions that is greater than the interest cost of obtaining the same amount of cash. Opportunities to realize earnings from the use of the proceeds equal to or greater than the interest required to be paid may not always be available, and a Fund intends to use the reverse repurchase technique only when BFA believes it will be advantageous to the Fund. The use of reverse repurchase agreements may exaggerate any increase or decrease in the value of a Fund’s assets. A Fund’s exposure to reverse repurchase agreements will be covered by liquid assets having a value equal to or greater than the Fund’s obligations under such commitments. The use of reverse repurchase agreements is a form of leverage, and the proceeds obtained by a Fund through reverse repurchase agreements may be invested in additional securities.

Securities of Investment Companies. Each Fund may invest in the securities of other investment companies (including money market funds) to the extent permitted by law, regulation, exemptive order or SEC staff guidance. Under the 1940 Act, a fund’s investment in investment companies is limited to, subject to certain exceptions, (i) 3% of the total outstanding voting stock of any one investment company, (ii) 5% of the fund’s total assets with respect to any one investment company, and (iii) 10% of the fund’s total assets with respect to investment companies in the aggregate. To the extent allowed by law or regulation, the Funds intend from time to time to invest their assets in securities of investment companies, including, but not limited to, money market funds, including those advised by BFA or otherwise affiliated with BFA, in excess of the limits discussed above. Other investment companies in which a Fund invests can be expected to incur fees and expenses for operations, such as investment advisory and administration fees, which would be in addition to those incurred by a Fund. Pursuant to guidance issued by the SEC staff, fees and expenses of money market funds used for cash collateral received in connection with loans of securities are not treated as Acquired Fund Fees and Expenses, which reflect the Fund’s pro rata share of the fees and expenses incurred by investing in other investment companies (as disclosed in the Prospectus, as applicable).

Short-Term Instruments and Temporary Investments. Each Fund may invest in short-term instruments, including variable rate demand notes, short-term municipal securities, short-term municipal money market funds and money market instruments, on an ongoing basis to provide liquidity or for other reasons. Money market instruments are generally short-term investments that may include, but are not limited to: (i) shares of money market funds (including those advised by BFA or otherwise affiliated with BFA); (ii) obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities (including government-sponsored enterprises); (iii) negotiable certificates of deposit, bankers’ acceptances, fixed-time deposits and other obligations of U.S. and non-U.S. banks (including non-U.S. branches) and similar institutions; (iv) commercial paper rated, at the date of purchase, “Prime-1” by Moody's, “F-1” by Fitch or “A-1” by S&P Global Ratings, or if unrated, of comparable quality as determined by BFA; (v) non-convertible corporate debt securities (e.g., bonds and debentures) with remaining maturities at the date of purchase of not more than 397 days and that have been determined to present minimal credit risks, in accordance with the requirements set forth in Rule 2a-7 under the 1940 Act; (vi) repurchase

agreements; and (vii) short-term U.S. dollar-denominated obligations of non-U.S. banks (including U.S. branches) that, in the opinion of BFA, are of comparable quality to obligations of U.S. banks that may be purchased by a Fund. Any of these instruments may be purchased on a current or forward-settled basis. Time deposits are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates. Bankers’ acceptances are time drafts drawn on commercial banks by borrowers, usually in connection with international transactions.

Future Developments. The Board may, in the future, authorize each Fund to invest in securities contracts and investments other than those listed in this SAI and in the Prospectus, provided they are consistent with each Fund's investment objective and do not violate any investment restrictions or policies.

General Considerations and Risks

A discussion of some of the principal risks associated with an investment in a Fund is contained in each Fund's Prospectus. An investment in a Fund should be made with an understanding that the value of the Fund’s portfolio securities may fluctuate in accordance with changes in the financial condition of the issuers of the portfolio securities, the value of bonds in general, and other factors that affect the market.

Borrowing Risk. Borrowing may exaggerate changes in the net asset value of Fund shares and in the return on a Fund’s portfolio. Borrowing will cost a Fund interest expense and other fees. The costs of borrowing may reduce a Fund’s return. Borrowing may cause a Fund to liquidate positions when it may not be advantageous to do so to satisfy its obligations.

Issuer Insolvency Risk. Each Fund's potential exposure to financially or operationally troubled issuers involves a high degree of credit and market risk, which may be heightened during an economic downturn or recession. Should an issuer of securities held by a Fund become involved in a bankruptcy proceeding, reorganization or financial restructuring, a wide variety of considerations make an evaluation of the outcome of a Fund’s exposure to the issuer uncertain. Insolvency of municipal issuers exposes investors to increased uncertainty and risks as compared to corporate issuers because municipalities typically are not subject to formalized bankruptcy proceedings and there often is not a process whereby creditor claims can be considered and addressed.

During the period of a bankruptcy proceeding, reorganization or financial restructuring, it is unlikely that each Fund will receive any interest payments on the securities of the issuer. Each Fund will be subject to significant uncertainty as to whether the reorganization or restructuring will be completed, and each Fund may bear certain extraordinary expenses to protect and recover its investment. Each Fund will also be subject to significant uncertainty as to when and in what manner and for what value the obligations evidenced by the securities of the issuer held by each Fund will eventually be satisfied. Even if a plan of reorganization or restructuring is adopted with respect to the securities of the issuer held by each Fund, there can be no assurance that the securities or other assets received by each Fund in connection with such plan of reorganization or restructuring will not have a lower value or income potential than may have been anticipated or no value. A Fund may be unable to enforce its claims or rights in any collateral or may have its claims or security interest in any collateral challenged, disallowed or subordinated to the claims or security interests of other creditors. In addition, amendments to the U.S. Bankruptcy Code or other relevant laws could alter the expected outcome or introduce greater uncertainty regarding the outcome of each Fund’s securities holdings in the issuer. In a bankruptcy proceeding, a reorganization or restructuring, the securities of the issuer held by each Fund could be re-characterized or each Fund may receive different securities or other assets, including equity securities. These types of equity securities include, but are not limited to: common stock; preferred stock (including convertible preferred stock); bonds, notes and debentures convertible into common or preferred stock; stock purchase warrants and rights; equity interests in trusts; and depositary receipts. The value of equity securities received by each Fund could decline if the financial condition of the issuer deteriorates or if overall market and economic conditions, or conditions within the issuer’s region or industry, deteriorate. Equity securities received by a Fund through a bankruptcy proceeding, reorganization or restructuring of an issuer would not be component securities of a Fund’s Underlying Index, which could subject a Fund to additional tracking error risk.

To the extent that each Fund receives other assets in connection with a bankruptcy proceeding, reorganization or financial restructuring, each Fund may also be subject to additional risks associated with the assets received. One example of assets that each Fund could receive is an interest in one or more loans made to the issuer as part of a workout agreed to by a consortium of lienholders and creditors of the issuer. Each Fund may receive such interests in loans to the extent permitted by the 1940 Act.

Securities or other assets received in a reorganization or restructuring typically entail a higher degree of risk than investments in securities of issuers that have not undergone a reorganization or restructuring and may be subject to heavy selling or downward pricing pressure after completion of the reorganization or restructuring. The post-reorganization/restructuring assets and securities may also be illiquid and difficult to sell or value. If each Fund participates in negotiations with respect to a plan of reorganization or restructuring with respect to securities of the issuer held by each Fund, each Fund also may be restricted from disposing such securities for a period of time. If each Fund becomes involved in such proceedings, each Fund may have more active participation in the affairs of the issuer than that assumed generally by an investor.

Liquidity Risk Management Rule Risk. In October 2016, the SEC adopted a liquidity risk management rule requiring open-end funds, including exchange-traded funds (“ETFs”) such as the Funds, to establish a liquidity risk management program and enhance disclosures regarding fund liquidity. There are exclusions from certain portions of the liquidity risk management program requirements for “in-kind” ETFs . The Funds will be required to comply with portions of the rule by December 1, 2018. The effect the rule will have on the Funds, including a Fund’s ability to rely on the exclusions, is not yet known, but the rule may impact a Fund’s performance and ability to achieve its investment objective.

Municipal Insurance. A municipal security may be covered by insurance that guarantees the bond’s scheduled payment of interest and repayment of principal. This type of insurance may be obtained by either (i) the issuer at the time the bond is issued (primary market insurance), or (ii) another party after the bond has been issued (secondary market insurance).

Both primary and secondary market insurance guarantee timely and scheduled repayment of all principal and payment of all interest on a municipal security in the event of default by the issuer, and cover a municipal security to its maturity, enhancing its credit quality and value.

Municipal security insurance does not insure against market fluctuations or fluctuations in each of the Funds' share price. In addition, a municipal security insurance policy will not cover: (i) repayment of a municipal security before maturity (redemption), (ii) nonpayment of principal or interest caused by negligence or bankruptcy of the paying agent, or (iii) prepayment or payment of an acceleration premium (except for a mandatory sinking fund redemption) or any other provision of a bond indenture that advances the maturity of the bond. A mandatory sinking fund redemption may be a provision of a municipal security issue whereby part of the municipal security issue may be retired before maturity.

Because a significant portion of the municipal securities issued and outstanding are insured by a small number of insurance companies, an event involving one or more of these insurance companies could have a significant adverse effect on the value of the securities insured by that insurance company and on the municipal markets as a whole.

Certain significant providers of insurance for municipal securities have recently incurred significant losses as a result of exposure to sub-prime mortgages and other lower credit quality investments that have experienced recent defaults or otherwise suffered extreme credit deterioration. As a result, such losses have reduced the insurers’ capital and called into question their continued ability to perform their obligations under such insurance if they are called upon to do so in the future. While an insured municipal security will typically be deemed to have the rating of its insurer, if the insurer of a municipal security suffers a downgrade in its credit rating or if the market discounts the value of the insurance provided by the insurer, the value of the municipal security would be more, if not entirely, dependent on the rating of the municipal security independent of insurance.

Municipal Market Disruption Risk. The value of municipal securities may be affected by uncertainties in the municipal market related to legislation or litigation involving the taxation of municipal securities or the rights of municipal securities holders in the event of a bankruptcy. Proposals to restrict or eliminate the U.S. federal income tax exemption for interest on municipal securities are introduced before the U.S. Congress from time to time. Proposals also may be introduced before state legislatures that would affect the state tax treatment of a municipal fund’s distributions. If such proposals were enacted, the availability of municipal securities and the value of a Fund’s holdings would be affected, and the Trustees would reevaluate the Fund’s investment objective and policies. Municipal bankruptcies are relatively rare, and certain provisions of the U.S. Bankruptcy Code governing such bankruptcies are unclear and remain untested. Further, the application of state law to municipal issuers could produce varying results among the states or among municipal securities issuers within a state. These legal uncertainties could affect the municipal securities market generally, certain specific segments of the market, or the relative credit quality of particular securities. Any of these effects could have a significant impact on the prices of some or all of the municipal securities held by a Fund.

Municipal Securities. The Funds invest in securities issued by states, municipalities and other political subdivisions, agencies, authorities and instrumentalities of states and multistate agencies or authorities. Municipal securities share the attributes of debt/fixed-income securities in general, but are generally issued by states, municipalities and other political subdivisions, agencies, authorities and instrumentalities of states and multi-state agencies or authorities. The municipal securities which the Funds may purchase include general obligation bonds and limited obligation bonds (or revenue bonds), including industrial development bonds issued pursuant to former U.S. federal tax law. General obligation bonds are obligations involving the credit of an issuer possessing taxing power and are payable from such issuer’s general revenues and not from any particular source. Limited obligation bonds are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise or other specific revenue source. Industrial development bonds generally are also revenue bonds and thus are not payable from the issuer’s general revenues. The credit and quality of industrial development bonds are usually related to the credit of the corporate user of the facilities. Payment of interest on and repayment of principal of such bonds is the responsibility of the corporate user (and/or any guarantor). The Funds may invest in private activity bonds, which are bonds issued by or on behalf of public authorities to obtain funds to provide privately operated housing facilities, airport, mass transit or port facilities, sewage disposal, solid waste disposal or hazardous waste treatment or disposal facilities and certain local facilities for water supply, gas or electricity. Other types of private activity bonds, the proceeds of which are used for the construction, equipment, repair or improvement of privately operated industrial or commercial facilities, may constitute municipal securities, although the current U.S. federal tax laws place substantial limitations on the size of such issues.

As each Fund approaches its termination date, it will transition its holdings to tax-free instruments, including AMT-free tax-exempt municipal notes (e.g., tax anticipation notes, revenue anticipation notes, tax and revenue anticipation notes, grant anticipation notes and bond anticipation notes); variable rate demand notes and obligations; tender option bonds; and municipal commercial paper.

Municipal notes are shorter-term municipal debt obligations. They may provide interim financing in anticipation of tax collection, receipt of grants, bond sales or revenue receipts. If there is a shortfall in the anticipated proceeds, repayment on a municipal note may be delayed or the note may not be fully repaid, and the Funds may lose money.

Municipal commercial paper is generally unsecured and issued to meet short-term financing needs. The lack of security presents some risk of loss to the Funds since, in the event of an issuer’s bankruptcy, unsecured creditors are repaid only out of the assets, if any, that remain after secured creditors are repaid.

Tender option bonds are synthetic floating rate or variable rate securities issued when long-term bonds are purchased in the primary or secondary market and then deposited into a trust. Custodial receipts are then issued to investors, such as the Funds, evidencing ownership interests in the trust. The remarketing agent for the trust sets a floating or variable rate on typically a weekly basis. The sponsor of a highly leveraged tender option bond trust generally will retain a liquidity provider to purchase the short-term floating rate interests at their original purchase price upon the occurrence of certain specified events. However, the liquidity provider may not be required to purchase the floating rate interests upon the occurrence of certain other events, for example, the downgrading of the municipal bonds owned by the tender option bond trust below investment grade. The general effect of these provisions is to pass to the holders of the floating rate interests the most severe credit risks associated with the municipal bonds owned by the tender option bond trust and to leave with the liquidity provider the interest rate risk (subject to a cap) and certain other risks associated with the municipal bonds. Tender option bonds may be considered derivatives, and may expose the Funds to the same risks as investments in derivatives, as well as risks associated with leverage, especially the risk of increased volatility. To the extent the Funds invest in tender option bonds, they also are exposed to credit risk associated with the liquidity provider retained by the sponsor of a tender bond option trust.

Variable rate demand obligations (“VRDOs”) are tax-exempt obligations that contain a floating or variable interest rate adjustment formula and a right of demand on the part of the holder thereof to receive payment of the unpaid principal balance plus accrued interest upon a short notice period not to exceed seven days. There is the possibility that because of default or insolvency the demand feature of VRDOs may not be honored. The interest rates are adjustable at intervals (ranging from daily to up to one year) to some prevailing market rate for similar investments, such adjustment formula being calculated to maintain the market rate of the VRDOs at approximately the par value of the VRDOs on the adjustment date. The adjustments typically are based upon the Public Securities Association Index or some other appropriate interest rate adjustment index.

Because of the interest rate adjustment formula, VRDOs are not comparable to fixed-rate securities. During periods of declining interest rates, a Fund’s yield on a VRDO will decrease and its shareholders will forego the opportunity for capital appreciation. During periods of rising interest rates, however, a Fund’s yield on a VRDO will increase and its shareholders will have a reduced risk of capital depreciation.

The market for municipal bonds may be less liquid than for taxable bonds. This means that it may be harder to buy and sell municipal securities, especially on short notice, than non-municipal securities. In addition, the municipal securities market is generally characterized as a buy and hold investment strategy. As a result, the accessibility of municipal securities in the market is generally greater closer to the original date of issue of the securities and lessens as the securities move further away from such issuance date.

Some longer-term municipal securities give the investor the right to “put” or sell the security at par (face value) within a specified number of days following the investor's request - usually one to seven days. This demand feature enhances a security's liquidity by shortening its effective maturity and enables it to trade at a price equal to or very close to par. If a demand feature terminates prior to being exercised, a Fund would hold the longer-term security, which could experience substantially more volatility.

Municipal securities are subject to credit and market risk. Generally, prices of higher quality issues tend to fluctuate more with changes in market interest rates than prices of lower quality issues and prices of longer maturity issues tend to fluctuate more than prices of shorter maturity issues.

Prices and yields on municipal securities are dependent on a variety of factors, including general money-market conditions, the financial condition of the issuer, general conditions of the municipal security market, the size of a particular offering, the maturity of the obligation and the rating of the issue. A number of these factors, including the ratings of particular issues, are subject to change from time to time. Information about the financial condition of an issuer of municipal securities may not be as extensive as that which is made available by corporations whose securities are publicly-traded. As a result, municipal securities may be more difficult to value than securities of public corporations.

Obligations of issuers of municipal securities are subject to insolvency concerns and, unlike obligations of corporate issuers, may not be subject to resolution in the event of insolvency or default through a bankruptcy proceeding. The U.S. Congress or state legislatures may seek to extend the time for payment of principal or interest, or both, or to impose other constraints upon enforcement of such obligations. In addition, municipal securities are subject to the risk that their tax treatment could be changed, thereby affecting the value of outstanding municipal securities. There is also the possibility that as a result of litigation or other conditions, such as passing of a referendum, the power or ability of issuers to meet their obligations for the payment of interest and principal on their municipal securities may be materially affected or their obligations may be found to be invalid or unenforceable. Such litigation or conditions may from time to time have the effect of introducing uncertainties in the market for municipal securities or certain segments thereof, or of materially affecting the credit risk with respect to particular bonds. Adverse economic, business, legal or political developments might affect all or a substantial portion of a Fund’s municipal securities in the same manner.

New or Unseasoned Municipal Issuers. A Fund may invest in municipal securities issued by entities that have not previously issued securities or that do not have an extensive history of issuing securities. Information regarding these issuers may be more limited than for other issuers. Securities of these issuers may be subject to volatility in their prices and may have a limited trading market, which could adversely affect a Fund’s ability to dispose of them and could reduce the price a Fund might be able to obtain for them.

Operational Risk. BFA and a Fund's other service providers may experience disruptions or operating errors such as processing errors or human errors, inadequate or failed internal or external processes, or systems or technology failures, that could negatively impact the Fund. While service providers are required to have appropriate operational risk management policies and procedures, their methods of operational risk management may differ from a Fund’s in the setting of priorities, the personnel and resources available or the effectiveness of relevant controls. BFA, through its monitoring and oversight of service providers, seeks to ensure that service providers take appropriate precautions to avoid and mitigate risks that could lead to disruptions and operating errors. However, it is not possible for BFA or the other Fund service providers to identify all of the operational risks that may affect a Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects.

Repurchase Agreement Risk. A repurchase agreement is an instrument under which the purchaser (i.e., a Fund) acquires a security and the seller agrees, at the time of the sale, to repurchase the security at a mutually agreed upon time and price. Repurchase agreements may be construed to be collateralized loans by the purchaser to the seller secured by the securities transferred to the purchaser. If a repurchase agreement is construed to be a collateralized loan, the underlying securities will not be considered to be owned by a Fund but only to constitute collateral for the seller’s obligation to pay the repurchase price. If the seller defaults on its obligation under the agreement, a Fund may suffer delays and incur costs or lose money in exercising its rights under the agreement. If the seller fails to repurchase the security and the market value of the security declines, a Fund may lose money.

Risk of Derivatives. A derivative is a financial contract, the value of which depends on, or is derived from, the value of an underlying asset, such as a security, a commodity (such as gold or silver), a currency or an index (a measure of value or rates, such as the S&P 500 or the prime lending rate). Each Fund may invest in variable rate demand notes and obligations, and tender option bonds, which may be considered derivatives. Compared to conventional securities, derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices and thus a Fund's losses may be greater if it invests in derivatives than if it invests only in conventional securities. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations. Derivatives generally involve the incurrence of leverage. To address such leverage and to prevent a Fund from being deemed to have issued senior securities as a result of an investment in derivatives, such Fund will segregate liquid assets equal to its obligations under the derivatives throughout the life of the investment.

When a derivative is used as a hedge against a position that a Fund holds or is committed to purchase, any loss generated by the derivative generally should be substantially offset by gains on the hedged investment, and vice versa. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains, and in some cases, hedging can cause losses that are not offset by gains, and the Fund will recognize losses on both the investment and the hedge. Hedges are sometimes subject to imperfect matching between the derivative and the underlying security, and there can be no assurance that a Fund’s hedging transactions, which entail additional transaction costs, will be effective.

Securities Lending Risk. A Fund may engage in securities lending. Securities lending involves the risk that a Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. A Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for a Fund. Substitute payments received by the Funds with respect to municipal securities lent, if any, will not constitute tax-exempt interest income to the Funds.

Risk of Investing in the Capital Goods Industry. Companies in the capital goods industry may be affected by fluctuations in the business cycle and by other factors affecting manufacturing demands. Companies in the capital goods industry depend heavily on corporate spending. Companies in the capital goods industry may perform well during times of economic expansion, and as economic conditions worsen, the demand for capital goods may decrease due to weakening demand, worsening business cash flows, tighter credit controls and deteriorating profitability. During times of economic volatility, corporate spending may fall and adversely affect the capital goods industry. This industry may also be affected by changes in interest rates, corporate tax rates and other government policies. Many capital goods are sold internationally and such companies are subject to market conditions in other countries and regions.

Risk of Investing in the Energy Sector. Companies in the energy sector are strongly affected by the levels and volatility of global energy prices, energy supply and demand, government regulations and policies, energy production and conservation efforts, technological change, development of alternative energy sources, and other factors that they cannot control. These companies may also lack resources and have limited business lines. Energy companies may have relatively high levels of debt and may be more likely to restructure their businesses if there are downturns in certain energy markets or in the global economy. If an energy company in a Fund's portfolio becomes distressed, a Fund could lose all or a substantial portion of its investment.

The energy sector is cyclical and is highly dependent on commodity prices; prices and supplies of energy may fluctuate significantly over short and long periods of time due to, among other things, national and international political changes, Organization of Petroleum Exporting Countries (“OPEC”) policies, changes in relationships among OPEC members and between OPEC and oil-importing nations, the regulatory environment, taxation policies, and the economy of the key energy-consuming countries. Commodity prices have recently been subject to increased volatility and declines, which may negatively affect companies in which a Fund invests.

Companies in the energy sector may be adversely affected by terrorism, natural disasters or other catastrophes. Companies in the energy sector are at risk of civil liability from accidents resulting in injury, loss of life or property, pollution or other environmental damage claims. Disruptions in the oil industry or shifts in fuel consumption may significantly impact companies in this sector. Significant oil and gas deposits are located in emerging markets countries where corruption and security may raise significant risks, in addition to the other risks of investing in emerging markets. Additionally, the Middle East, where many companies in the energy sector may operate, has historically and recently experienced widespread social unrest.

Companies in the energy sector may also be adversely affected by changes in exchange rates, interest rates, economic conditions, tax treatment, government regulation and intervention, negative perception, efforts at energy conservation and world events in the regions in which the companies operate (e.g., expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and repatriation of capital, military coups, social unrest, violence or labor unrest). Because a significant portion of revenues of companies in this sector is derived from a relatively small number of customers that are largely composed of governmental entities and utilities, governmental budget constraints may have a significant impact on the stock prices of companies in this sector. The energy sector is highly regulated. Entities operating in the energy sector are subject to significant regulation of nearly every aspect of their operations by federal, state and local governmental agencies. Such regulation can change rapidly or over time in both scope and intensity. Stricter laws, regulations or enforcement policies could be enacted in the future which would likely increase compliance costs and may materially adversely affect the financial performance of companies in the energy sector.

governmental intervention in the operations of financial companies and financial markets may materially and adversely affect the companies in which a Fund invests, including legislation in many countries that may increase government regulation, repatriation and other intervention. The impact of governmental intervention and legislative changes on any individual financial company or on the financials sector as a whole cannot be predicted. The valuation of financial companies has been and continues to be subject to unprecedented volatility and may be influenced by unpredictable factors, including interest rate risk and sovereign debt default. Certain financial businesses are subject to intense competitive pressures, including market share and price competition. Financial companies in foreign countries are subject to market specific and general regulatory and interest rate concerns. In particular, government regulation in certain foreign countries may include taxes and controls on interest rates, credit availability, minimum capital requirements, bans on short sales, limits on prices and restrictions on currency transfers. In addition, companies in the financials sector may be the targets of hacking and potential theft of proprietary or customer information or disruptions in service, which could have a material adverse effect on their businesses.

In addition, because the products and services of many companies in the healthcare sector affect the health and well-being of many individuals, these companies are especially susceptible to extensive litigation based on product liability and similar claims. Healthcare companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the healthcare sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly, which can result in increased development costs, delayed cost recovery and loss of competitive advantage to the extent that rival companies have developed competing products or procedures, adversely affecting the company’s revenues and profitability. In other words, delays in the regulatory approval process may diminish the opportunity for a company to profit from a new product or to bring a new product to market, which could have a material adverse effect on a company’s business. Healthcare companies may also be strongly affected by scientific biotechnology or technological developments, and their products may quickly become obsolete. Also, many healthcare companies offer products and services that are subject to governmental regulation and may be adversely affected by changes in governmental policies or laws. Changes in governmental policies or laws may span a wide range of topics, including cost control, national health insurance, incentives for compensation in the provision of healthcare services, tax incentives and

penalties related to healthcare insurance premiums, and promotion of prepaid healthcare plans. In addition, a number of legislative proposals concerning healthcare have been considered by the U.S. Congress in recent years. It is unclear what proposals will ultimately be enacted, if any, and what effect they may have on companies in the healthcare sector.

Risk of Investing in the Industrials Sector. The value of securities issued by companies in the industrials sector may be adversely affected by supply of and demand for both their specific products or services and for industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events and economic conditions may affect the performance of companies in the industrials sector. Aerospace and defense companies, a component of the industrials sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on government demand for their products and services. Thus, the financial condition of, and investor interest in, aerospace and defense companies are heavily influenced by governmental defense spending policies, which are typically under pressure from efforts to control government budgets. Transportation stocks, a component of the industrials sector, are cyclical and can be significantly affected by economic changes, fuel prices, labor relations and insurance costs. Transportation companies in certain countries may also be subject to significant government regulation and oversight, which may adversely affect their businesses. For example, commodity price declines and unit volume reductions resulting from an over-supply of materials used in the industrials sector can adversely affect the sector. Furthermore, companies in the industrials sector may be subject to liability for environmental damage, product liability claims, depletion of resources, and mandated expenditures for safety and pollution control.

Risk of Investing in Municipal Securities in the Utilities Sector. Certain municipal securities are issued by public bodies, including state and municipal utility authorities, to, among other things, finance the operation or expansion of utility entities. Various future economic and other conditions may adversely affect utility entities, including inflation, increases in financing requirements, increases in raw material costs and other operating costs, changes in demand for services and the effects of environmental and other governmental regulations. Municipal securities that are issued to finance a particular utility project often depend on revenues from that project to make principal and interest payments. Adverse conditions and developments affecting a particular utility project can result in lower revenues to the issuer of the municipal securities. Certain utilities are subject to specific risks. Gas utilities are subject to risks of supply conditions and increased competition from other providers

of utility services. In addition, gas utilities are affected by gas prices, which may be magnified to the extent that a gas utility enters into long-term contracts for the purchase or sale of gas at a fixed price, since such prices may change significantly and to the disadvantage of the gas utility.

Risk of Investing in Municipal Securities Issued By School Districts. School districts rely, in part, on funding appropriations from, among others, the federal government and state governments. As a result, municipal securities issued by school districts may be adversely affected by political and economic changes at the state or federal levels, such as decreased tax or other revenues, spending reductions or changes in appropriations. Municipal securities that are issued to finance a particular school district project often depend on revenues from that project to make principal and interest payments. Adverse conditions and developments affecting a particular project can result in lower revenues to the issuer of the municipal securities. Investors in these securities, similar to investors in municipal securities generally, face heightened risk of loss upon insolvency of the school district issuers because there is often no ready source of funding to pay the bonds other than the local tax base, which a bankruptcy court or administrator does not control.

Risk of Investing in the Technology Sector. Technology companies are characterized by periodic new product introductions, innovations and evolving industry standards, and, as a result, face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Companies in the technology sector are often smaller and less experienced companies and may be subject to greater risks than larger companies; these risks may be heightened for technology companies in foreign markets. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face product obsolescence due to rapid technological developments and frequent new product introduction, changes in consumer and business purchasing patterns, unpredictable changes in growth rates and competition for the services of qualified personnel. In addition, a rising interest rate environment tends to negatively affect companies in the technology sector because, in such an environment, those companies with high market valuations may appear less attractive to investors, which may cause sharp decreases in the companies’ market prices. Companies in the technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. The technology sector may also be adversely affected by changes or trends in commodity prices, which may be influenced or characterized by unpredictable factors. Finally, while all companies may be susceptible to network security breaches, certain companies in the technology sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.

Risk of Investing in the Transportation Infrastructure Industry. Municipal securities include, among others, bonds payable from fuel taxes and tolls for municipal toll roads, as well as general airport bonds. Issuers in the transportation infrastructure industry can be significantly affected by economic changes, fuel prices, labor relations, technology developments, exchange rates, industry competition, insurance costs and deteriorating public infrastructure, such as bridges, roads, rails, ports and airports. Municipal securities that are issued to finance a particular transportation project often depend on revenues from that project to make principal and interest payments. Adverse conditions and developments affecting a particular project can result in lower revenues to the issuer of the municipal securities. Other risk factors that may affect the transportation infrastructure industry include the risk of increases in fuel and other operating costs and the effects of regulatory changes or other government decisions.

Tax Risks Associated with Municipal Securities. As with any investment, you should consider how your investment in shares of each Fund will be taxed. The tax information in the relevant Prospectus and this SAI is provided as general information. You should consult your own tax professional about the tax consequences of an investment in shares of each Fund.

Unless your investment in shares is made through a tax-exempt entity or tax-deferred retirement account, such as an individual retirement account, you need to be aware of the possible tax consequences when each Fund makes distributions or you sell Fund shares. In general, given its investment strategy, each Fund would not be an appropriate investment for a tax deferred retirement account such as an IRA or a tax-exempt investor.

In response to the national economic downturn in recent years, governmental cost burdens may be reallocated among federal, state and local governments. Also, as a result of the downturn, many state and local governments are experiencing significant reductions in revenues and are consequently experiencing difficulties meeting ongoing expenses. Certain of these state or local governments may have difficulty paying principal or interest on their outstanding debt and may experience ratings downgrades of their debt.

Proxy Voting Policy

The Board has delegated the voting of proxies for each Fund’s securities to BFA pursuant to BFA’s proxy voting guidelines and procedures (the “BlackRock Proxy Voting Guidelines”). Under the BlackRock Proxy Voting Guidelines, BFA will vote proxies related to Fund securities in the best interests of a Fund and its shareholders. From time to time, a vote may present a conflict between the interests of a Fund’s shareholders, on the one hand, and those of BFA, or any affiliated person of a Fund or BFA, on the other. BFA maintains policies and procedures that are designed to prevent undue influence on BFA’s proxy voting activity that might stem from any relationship between the issuer of a proxy (or any dissident shareholder) and BFA, BFA’s affiliates, a Fund or a Fund’s affiliates. Most conflicts are managed through a structural separation of BFA’s Corporate Governance Group from BFA’s employees with sales and client responsibilities. In addition, BFA maintains procedures to ensure that all engagements with corporate issuers or dissident shareholders are managed consistently and without regard to BFA’s relationship with the issuer of the proxy or the dissident shareholder. In certain instances, BFA may determine to engage an independent fiduciary to vote proxies as a further safeguard to avoid potential conflicts of interest or as otherwise required by applicable law. Copies of the Funds' Proxy Voting Policy and the BlackRock Proxy Voting Guidelines are attached as Appendix A.

Information with respect to how BFA voted proxies relating to the Funds' portfolio securities during the 12-month period ended June 30 is available: (i) without charge, upon request, by calling 1-800-iShares (1-800-474-2737) or through the Funds' website at www.iShares.com; and (ii) on the SEC’s website at www.sec.gov.

Portfolio Holdings Information

The Board has adopted a policy regarding the disclosure of the Funds' portfolio holdings information that requires that such information be disclosed in a manner that: (i) is consistent with applicable legal requirements and in the best interests of each Fund’s respective shareholders; (ii) does not put the interests of BFA, the Distributor or any affiliated person of BFA or the Distributor, above those of Fund shareholders; (iii) does not advantage any current or prospective Fund shareholders over any other current or prospective Fund shareholders, except to the extent that certain Entities (as described below) may receive portfolio holdings information not available to other current or prospective Fund shareholders in connection with the dissemination of information necessary for transactions in Creation Units, as discussed below, and certain information may be provided to personnel of BFA and its affiliates who manage funds that invest a significant percentage of their assets in shares of the Fund for the purpose of facilitating risk management and hedging activities; and (iv) does not provide selective access to portfolio holdings information except pursuant to the procedures outlined below and to the extent appropriate confidentiality arrangements limiting the use of such information are in effect. The “Entities” referred to in sub-section (iii) above are generally limited to National Securities Clearing Corporation (“NSCC”) members, subscribers to various fee-based subscription services, large institutional investors (known as “Authorized Participants”) that have been authorized by the Distributor to purchase and redeem large blocks of shares pursuant to legal requirements and market makers and other institutional market participants and entities that provide information or transactional services.

Each business day, each Fund's portfolio holdings information is provided to the Distributor or other agent for dissemination through the facilities of the NSCC and/or other fee-based subscription services to NSCC members and/or subscribers to those other fee-based subscription services, including market makers and Authorized Participants, and to entities that publish and/or analyze such information in connection with the process of purchasing or redeeming Creation Units or

trading shares of the Funds in the secondary market or evaluating such potential transactions. This information typically reflects each Fund’s anticipated holdings on the following business day.

Daily access to information concerning the Funds' portfolio holdings is permitted: (i) to certain personnel of those service providers that are involved in portfolio management and providing administrative, operational, risk management, or other support to portfolio management; and (ii) to other personnel of the Funds' investment adviser, the Distributor and their affiliates, and the administrator, custodian and fund accountant who deal directly with, or assist in, functions related to investment management, distribution, administration, custody, securities lending and fund accounting, as may be necessary to conduct business in the ordinary course in a manner consistent with federal securities laws and regulations thereunder. In addition, each Fund discloses its fixed-income and/or equity portfolio holdings daily at www.iShares.com. More information about this disclosure is available at www.iShares.com.

Portfolio holdings information made available in connection with the creation/redemption process may be provided to other entities that provide services to the Funds in the ordinary course of business after it has been disseminated to the NSCC. From time to time, information concerning portfolio holdings other than portfolio holdings information made available in connection with the creation/redemption process, as discussed above, may be provided to other entities that provide services to the Funds, including rating or ranking organizations, in the ordinary course of business, no earlier than one business day following the date of the information.

Each Fund discloses its complete portfolio holdings schedule in public filings with the SEC within 70 days of the end of the second and fourth fiscal quarters and within 60 days of the end of the first and third fiscal quarters and will provide such information to shareholders as required by federal securities laws and regulations thereunder. A Fund may, however, voluntarily disclose all or part of its portfolio holdings other than in connection with the creation/redemption process, as discussed above, in advance of required filings with the SEC, provided that such information is made generally available to all shareholders and other interested parties in a manner that is consistent with the above policy for disclosure of portfolio holdings information. Such information may be made available through a publicly available website or other means that make the information available to all likely interested parties contemporaneously.

The Board reviews the policy and procedures for disclosure of portfolio holdings information at least annually.

Construction and Maintenance of the Underlying Indexes

Descriptions of the Underlying Indexes are provided below.

The S&P Fixed Income Indexes

Issue Changes. General oversight responsibility for the Standard & Poor’s Financial Services LLC (“S&P”) indexes, including overall policy guidelines and methodology, is handled by an S&P Index Committee. Maintenance of component investments, including additions and deletions to these investments, is the responsibility of separate regional index committees composed of S&P Dow Jones Indices LLC (“S&P DJI”) staff specialized in the various fixed-income markets. Public announcements of index changes as the result of committee decisions will generally be made two business days in advance of the anticipated effective date whenever possible, although for exceptional corporate events announcements may be made earlier.

Index Maintenance. Maintaining the S&P Fixed Income Indexes includes monitoring and completing the adjustments for bond additions and deletions, par amount changes, rating changes and corporate actions.

Index Availability. Most S&P Fixed Income Indexes are calculated at the end of the business day. All S&P Indexes are available from major data vendors.

S&P AMT-Free Municipal Series 2018 Index^TM

Number of Components: approximately 4,259

Index Description. The S&P AMT-Free Municipal Series 2018 Index^TM is a broad, comprehensive, market value weighted index designed to measure the performance of the investment-grade, non-callable U.S. municipal bond market with maturities in 2018. As of March 31, 2018, the Underlying Index consisted of 4,259 bonds, with a total market value of $35.2 billion.

S&P AMT-Free Municipal Series 2019 Index^TM

Number of Components: approximately 4,150

Index Description. The S&P AMT-Free Municipal Series 2019 Index^TM is a broad, comprehensive, market value weighted index designed to measure the performance of the investment-grade, non-callable U.S. municipal bond market with maturities in 2019. As of March 31, 2018, the Underlying Index consisted of 4,150 bonds, with a total market value of $35.8 billion.

S&P AMT-Free Municipal Series 2020 Index^TM

Number of Components: approximately 3,866

Index Description. The S&P AMT-Free Municipal Series 2020 Index^TM is a broad, comprehensive, market value weighted index designed to measure the performance of the investment-grade, non-callable U.S. municipal bond market with maturities in 2020. As of March 31, 2018, the Underlying Index consisted of 3,866 bonds, with a total market value of $33.1 billion.

Index Methodology. In order for a bond to be classified as eligible for inclusion in an Underlying Index, a bond must meet all of the following criteria: (i) the bond issuer is a state or local government or agency such that interest on the bonds is exempt from U.S. federal income taxes and the federal AMT as determined by the Index Provider in accordance with its methodology; (ii) the bond must be denominated in U.S. dollars; (iii) the bond must have a rating of at least BBB- by S&P Global Ratings, Baa3 by Moody's, or BBB- by Fitch. A bond must be rated by only one of these three rating agencies in order to qualify for the index. A bond with an “expected” rating, as denoted by data providers, of at least BBB- by S&P Global Ratings, Baa3 by Moody’s, or BBB- by Fitch will qualify for the index as well. For the avoidance of doubt, the lowest rating will be used in determining if a bond is investment grade; and (iv) each bond in the Underlying Index must have a minimum maturity par amount of $2 million to be eligible for inclusion. To remain in an Underlying Index, bonds must maintain a minimum maturity par amount greater than or equal to $2 million as of each rebalancing date and must maintain a minimum maturity par amount greater than or equal to $2 million as of six days prior to last Business Day of each month (“Rebalancing Reference Date”). “Business Day” is defined as any day that U.S. municipal bonds are traded, as determined by The Securities Industry and Financial Markets Association and/or the New York Stock Exchange (“NYSE”). All bonds in each Underlying Index will mature between June 1 and September 1 of the relevant year. When a bond that is included in an Underlying Index matures, its maturity value will be represented in the Underlying Index by cash throughout the remaining life of the Underlying Index. For each Underlying Index, by September 1 of the relevant year, the Underlying Index value will be represented by cash as no securities will remain in the Underlying Index. At each monthly rebalancing, no index constituent can represent more than 30% of the weight of the Underlying Index, and the five highest weighted index constituents do not account for more than 65% of the weight of the index in aggregate. The following types of bonds are specifically excluded from each Underlying Index: bonds subject to the AMT, bonds with early redemption dates (callable provisions), housing bonds, industrial bonds, tobacco bonds, health care bonds, conduit bonds where the obligor is a for-profit institution, non-rated bonds, notes, taxable municipals, variable rate debt, commercial paper, derivative securities (inverse floaters, forwards, and swaps).

Component Selection Criteria. Eligible bonds are approved by the S&P Index Committee that oversees the management of the Underlying Indexes and are added to an Underlying Index on the next Rebalancing Reference Date, subject to the schedule of the monthly rebalancing procedures.

Index Maintenance. Each Underlying Index is a market value weighted index. S&P's pricing division, Standard & Poors Securities Evaluations, Inc., reports the price of each bond in the index each day. The prices used in the index calculation will add the accrued interest for each bond to the price reported by S&P. The total return is calculated by aggregating the interest return, reflecting the return due to paid and accrued interest, and principal return, reflecting the capital gains or losses due to changes in S&P's end-of-day price and principal repayments and the reinvestment return, reflecting the reinvestment of related cash flows. Each Underlying Index is generally reviewed and rebalanced on a monthly basis. The S&P Index Committee, nevertheless, reserves the right to make adjustments to an Underlying Index at any time that it believes appropriate. Additions, deletions and other changes to an Underlying Index arising from the monthly rebalancing are

published three Business Days prior to the last business day of the month (the Announcement Date). Publicly available information, up to and including the close on the sixth Business Day preceding the Rebalancing Date, is considered in the rebalancing. Underlying Index changes published in the announcement will not normally be subject to revision and will become effective after the close. However, credit rating changes that occur on a Business Day prior to the Rebalancing Date will be reflected in the rebalancing, where such changes would cause any one of the following: (i) deletion of an index bond because it no longer meets the eligibility criteria; (ii) removal of a bond from the additions list because it is no longer an eligible bond; or (iii) removal of an index bond from the deletions list because it is once again eligible. Users will be notified of any ratings-driven changes to the rebalancing.

Investment Restrictions

Each Fund has adopted its investment objective as a non-fundamental investment policy. Therefore, each Fund may change its investment objective and its Underlying Index without shareholder approval. The Board has adopted as fundamental policies the following numbered investment restrictions, which cannot be changed without the approval of the holders of a majority of the applicable Fund’s outstanding voting securities. A vote of a majority of the outstanding voting securities of a Fund is defined in the 1940 Act as the lesser of (i) 67% or more of the voting securities present at a shareholder meeting, if the holders of more than 50% of the outstanding voting securities of the Fund are present or represented by proxy, or (ii) more than 50% of outstanding voting securities of the Fund.

Each of the Funds (except the iShares iBonds Sep 2020 Term Muni Bond ETF) will not:

1.	Concentrate its investments (i.e., invest 25% or more of its total assets in the securities of a particular industry or group of industries), except that each Fund will concentrate to approximately the same extent that its Underlying Index concentrates in the securities of such particular industry or group of industries. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities), repurchase agreements collateralized by U.S. government securities, and securities of state or municipal governments and their political subdivisions are not considered to be issued by members of any industry.
2.	Borrow money, except that (i) each Fund may borrow from banks for temporary or emergency (not leveraging) purposes, including the meeting of redemption requests which might otherwise require the untimely disposition of securities; and (ii) each Fund may, to the extent consistent with its investment policies, enter into repurchase agreements, reverse repurchase agreements, forward roll transactions and similar investment strategies and techniques. To the extent that it engages in transactions described in (i) and (ii), each Fund will be limited so that no more than 33 1/3% of the value of its total assets (including the amount borrowed) is derived from such transactions. Any borrowings which come to exceed this amount will be reduced in accordance with applicable law.
3.	Issue any senior security, except as permitted under the 1940 Act, as interpreted, modified or otherwise permitted by regulatory authority having jurisdiction, from time to time.
4.	Make loans, except as permitted under the 1940 Act, as interpreted, modified or otherwise permitted by regulatory authority having jurisdiction, from time to time.
5.	Purchase or sell real estate unless acquired as a result of ownership of securities or other instruments (but this restriction shall not prevent each Fund from investing in securities of companies engaged in the real estate business or securities or other instruments backed by real estate or mortgages), or commodities or commodity contracts (but this restriction shall not prevent each Fund from trading in futures contracts and options on futures contracts, including options on currencies to the extent consistent with each Fund’s investment objective and policies).
6.	Engage in the business of underwriting securities issued by other persons, except to the extent that each Fund may technically be deemed to be an underwriter under the 1933 Act, in disposing of portfolio securities.

The iShares iBonds Sep 2020 Term Muni Bond ETF will not:

1. Concentrate its investments in a particular industry, as that term is used in the Investment Company Act, except that the Fund will concentrate to approximately the same extent that its Underlying Index concentrates in the securities of a particular industry or group of industries.

2. Borrow money, except as permitted under the Investment Company Act.

3. Issue senior securities to the extent such issuance would violate the Investment Company Act.

4. Purchase or hold real estate, except the Fund may purchase and hold securities or other instruments that are secured by, or linked to, real estate or interests therein, securities of real estate investment trusts, mortgage-related securities and securities of issuers engaged in the real estate business, and the Fund may purchase and hold real estate as a result of the ownership of securities or other instruments.

5. Underwrite securities issued by others, except to the extent that the sale of portfolio securities by the Fund may be deemed to be an underwriting or as otherwise permitted by applicable law.

6. Purchase or sell commodities or commodity contracts, except as permitted by the Investment Company Act.

7. Make loans to the extent prohibited by the Investment Company Act.

In addition to the investment restrictions adopted as fundamental policies, set forth above, each Fund (except the iShares iBonds Sep 2020 Term Muni Bond ETF) has adopted a non-fundamental policy not to invest in the securities of a company for the purpose of exercising management or control, or purchase or otherwise acquire any illiquid security, except as permitted under the 1940 Act, which currently permits up to 15% of each Fund’s net assets to be invested in illiquid securities (calculated at the time of investment). Except with regard to the fundamental policy relating to senior securities set forth in (3) above, if any percentage restriction described above is complied with at the time of an investment, a later increase or decrease in percentage resulting from a change in values of assets will not constitute a violation of such restriction.

BFA monitors the liquidity of restricted securities in each Fund’s portfolio. In reaching liquidity decisions, BFA considers the following factors:

•	The frequency of trades and quotes for the security;
•	The number of dealers wishing to purchase or sell the security and the number of other potential purchasers;
•	Dealer undertakings to make a market in the security; and
•	The nature of the security and the nature of the marketplace in which it trades (e.g., the time needed to dispose of the security, the method of soliciting offers and the mechanics of transfer).

Under normal circumstances, each Fund will invest at least 80% of the value of its net assets, plus the amount of any borrowings for investment purposes, in investments the income of which is free from federal income tax, including AMT. This policy is a fundamental policy of the Fund and may not be changed without a vote of a majority of the Fund’s outstanding voting securities, as defined in the 1940 Act. Each Fund has adopted a non-fundamental investment policy to invest, under normal circumstances, at least 80% of the value of its net assets, plus the amount of any borrowings for investment purposes, in securities in each Fund's Underlying Index. Each Fund also has adopted a policy to provide its shareholders with at least 60 days’ prior written notice of any change in such policy. If, subsequent to an investment, an 80% requirement is no longer met, a Fund’s future investments will be made in a manner that will bring the Fund into compliance with this policy.

Each Fund has adopted a non-fundamental limitation such that, under normal market conditions, any borrowings by the Fund will not exceed 10% of the Fund’s net assets.

Each Fund may not purchase securities of other investment companies, except to the extent permitted by the 1940 Act. As a matter of policy, however, a Fund will not purchase shares of any registered open-end investment company or registered unit investment trust, in reliance on Section 12(d)(1)(F) or (G) (the “fund of funds” provisions) of the 1940 Act, at any time the Fund has knowledge that its shares are purchased by another investment company investor in reliance on the provisions of subparagraph (G) of Section 12(d)(1).

Notations Regarding the iShares iBonds Sep 2020 Term Muni Bond ETF's Fundamental Investment Restrictions

The following notations are not considered to be part of the Fund's fundamental investment restrictions and are subject to change without shareholder approval.

more of a fund’s total assets in one or more issuers conducting their principal activities in the same industry or group of industries constitutes concentration. It is possible that interpretations of concentration could change in the future. The policy in (1) above will be interpreted to refer to concentration as that term may be interpreted from time to time. The policy also will be interpreted to permit investment without limit in the following: securities of the U.S. government and its agencies or instrumentalities; securities of state, territory, possession or municipal governments and their authorities, agencies, instrumentalities or political subdivisions; and repurchase agreements collateralized by any such obligations. Accordingly, issuers of the foregoing securities will not be considered to be members of any industry. There also will be no limit on investment in issuers domiciled in a single jurisdiction or country. Finance companies will be considered to be in the industries of their parents if their activities are primarily related to financing the activities of the parents. Each foreign government will be considered to be a member of a separate industry. With respect to the Fund's industry classifications, the Fund currently utilizes any one or more of the industry sub-classifications used by one or more widely recognized market indexes or rating group indexes, and/or as defined by Fund management. The policy also will be interpreted to give broad authority to the Fund as to how to classify issuers within or among industries.

With respect to the fundamental policy relating to borrowing money set forth in (2) above, the Investment Company Act permits each Fund to borrow money in amounts of up to one-third of the Fund’s total assets from banks for any purpose, and to borrow up to 5% of the Fund’s total assets from banks or other lenders for temporary purposes. (The Fund’s total assets include the amounts being borrowed.) To limit the risks attendant to borrowing, the Investment Company Act requires each Fund to maintain at all times an “asset coverage” of at least 300% of the amount of its borrowings. Asset coverage means the ratio that the value of the Fund's total assets (including amounts borrowed), minus liabilities other than borrowings, bears to the aggregate amount of all borrowings. Borrowing money to increase portfolio holdings is known as “leveraging.” Certain trading practices and investments, such as reverse repurchase agreements, may be considered to be borrowings or involve leverage and thus are subject to the Investment Company Act restrictions. In accordance with SEC staff guidance and interpretations, when the Fund engages in such transactions, the Fund instead of maintaining asset coverage of at least 300%, may segregate or earmark liquid assets, or enter into an offsetting position, in an amount at least equal to the Fund’s exposure, on a mark-to-market basis, to the transaction (as calculated pursuant to requirements of the SEC). The policy in (2) above will be interpreted to permit each Fund to engage in trading practices and investments that may be considered to be borrowing or to involve leverage to the extent permitted by the Investment Company Act and to permit the Fund to segregate or earmark liquid assets or enter into offsetting positions in accordance with the Investment Company Act. Short-term credits necessary for the settlement of securities transactions and arrangements with respect to securities lending will not be considered to be borrowings under the policy. Practices and investments that may involve leverage but are not considered to be borrowings are not subject to the policy.

With respect to the fundamental policy relating to underwriting set forth in (5) above, the Investment Company Act does not prohibit each Fund from engaging in the underwriting business or from underwriting the securities of other issuers; in fact, in the case of diversified funds, the Investment Company Act permits the Fund to have underwriting commitments of up to 25% of its assets under certain circumstances. Those circumstances currently are that the amount of the Fund's underwriting commitments, when added to the value of the Fund’s investments in issuers where the Fund owns more than 10% of the outstanding voting securities of those issuers, cannot exceed the 25% cap. A fund engaging in transactions involving the acquisition or disposition of portfolio securities may be considered to be an underwriter under the 1933 Act. Although it is not believed that the application of the 1933 Act provisions described above would cause the Fund to be engaged in the business of underwriting, the policy in (5) above will be interpreted not to prevent the Fund from engaging in transactions involving the acquisition or disposition of portfolio securities, regardless of whether the Fund may be considered to be an underwriter under the 1933 Act or is otherwise engaged in the underwriting business to the extent permitted by applicable law.

With respect to the fundamental policy relating to lending set forth in (7) above, the Investment Company Act does not prohibit each Fund from making loans (including lending its securities); however, SEC staff interpretations currently prohibit funds from lending more than one-third of their total assets (including lending its securities), except through the purchase of debt obligations or the use of repurchase agreements. In addition, collateral arrangements with respect to options, forward currency and futures transactions and other derivative instruments (as applicable), as well as delays in the settlement of securities transactions, will not be considered loans.

Under the iShares iBonds Sep 2020 Term Muni Bond ETF's non-fundamental investment restrictions, which may be changed by the Board without shareholder approval, the iShares iBonds Sep 2020 Term Muni Bond ETF may not:

Make short sales of securities or maintain a short position, except to the extent permitted by the Fund's Prospectus and SAI, as amended from time to time, and applicable law.

Continuous Offering

The method by which Creation Units are created and traded may raise certain issues under applicable securities laws. Because new Creation Units are issued and sold by the Funds on an ongoing basis, at any point a “distribution,” as such term is used in the 1933 Act, may occur. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject them to the prospectus delivery requirement and liability provisions of the 1933 Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into constituent shares and sells such shares directly to customers or if it chooses to couple the creation of new shares with an active selling effort involving solicitation of secondary market demand for shares. A determination of whether one is an underwriter for purposes of the 1933 Act must take into account all of the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case and the examples mentioned above should not be considered a complete description of all the activities that could lead to a categorization as an underwriter.

Broker-dealer firms should also note that dealers who are not “underwriters” but are effecting transactions in shares, whether or not participating in the distribution of shares, generally are required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(a)(3) of the 1933 Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. Firms that incur a prospectus delivery obligation with respect to shares of the Funds are reminded that, pursuant to Rule 153 under the 1933 Act, a prospectus delivery obligation under Section 5(b)(2) of the 1933 Act owed to an exchange member in connection with a sale on the Listing Exchange generally is satisfied by the fact that the prospectus is available at the Listing Exchange upon request. The prospectus delivery mechanism provided in Rule 153 is available only with respect to transactions on an exchange.

The Board has concluded that, based on each Trustee’s experience, qualifications, attributes or skills on an individual basis and in combination with those of the other Trustees, each Trustee should serve as a Trustee of the Board. Among the attributes common to all Trustees are their ability to review critically, evaluate, question and discuss information provided to them, to interact effectively with the Funds' investment adviser, other service providers, counsel and the independent registered public accounting firm, and to exercise effective business judgment in the performance of their duties as Trustees. A Trustee’s ability to perform his or her duties effectively may have been attained through the Trustee’s educational background or professional training; business, consulting, public service or academic positions; experience from service as a Board member of the Funds and the other funds in the Trust (and any predecessor funds), other investment funds, public companies, or non-profit entities or other organizations; and/or other life experiences.

Board – Leadership Structure and Oversight Responsibilities

Overall responsibility for oversight of the Funds rests with the Board. The Board has engaged BFA to manage the Funds on a day-to-day basis. The Board is responsible for overseeing BFA and other service providers in the operations of the Funds in accordance with the provisions of the 1940 Act, applicable provisions of state and other laws and the Trust’s charter. The Board is currently composed of ten members, eight of whom are Independent Trustees. The Board currently conducts regular in person meetings four times a year. In addition, the Board frequently holds special in person or telephonic meetings or informal conference calls to discuss specific matters that may arise or require action between regular meetings. The Independent Trustees meet regularly outside the presence of management, in executive session or with other service providers to the Trust.

The Board has appointed an Independent Trustee to serve in the role of Board Chair. The Board Chair’s role is to preside at all meetings of the Board and to act as a liaison with service providers, officers, attorneys, and other Trustees generally between meetings. The Board Chair may also perform such other functions as may be delegated by the Board from time to time. The Board has established seven standing Committees: a Nominating and Governance Committee, an Audit Committee, a 15(c) Committee, a Securities Lending Committee, a Risk Committee, an Equity Plus Committee and a Fixed Income Plus Committee to assist the Board in the oversight and direction of the business and affairs of the Funds, and from time to time the Board may establish ad hoc committees or informal working groups to review and address the policies and practices of the Funds with respect to certain specified matters. The Chair of each standing Committee is an Independent Trustee. The role of the Chair of each Committee is to preside at all meetings of the Committee and to act as a liaison with service providers, officers, attorneys and other Trustees between meetings. Each standing Committee meets regularly to conduct the oversight functions delegated to the Committee by the Board and reports its finding to the Board. The Board and each standing Committee conduct annual assessments of their oversight function and structure. The Board has determined that the Board’s leadership structure is appropriate because it allows the Board to exercise independent judgment over management and it allocates areas of responsibility among committees of Independent Trustees and the full Board to enhance effective oversight.

Day-to-day risk management with respect to the Funds is the responsibility of BFA or other service providers (depending on the nature of the risk), subject to the supervision of BFA. Each Fund is subject to a number of risks, including investment, compliance, operational, reputational, counterparty and valuation risks, among others. While there are a number of risk management functions performed by BFA and other service providers, as applicable, it is not possible to identify and eliminate all of the risks applicable to the Funds. The Trustees have an oversight role in this area, satisfying themselves that risk management processes and controls are in place and operating effectively. Risk oversight forms part of the Board’s general oversight of each Fund and is addressed as part of various Board and committee activities. In some cases, risk management issues are specifically addressed in presentations and discussions. For example, BFA has an independent dedicated Risk and Quantitative Analysis Group (“RQA”) that assists BFA in managing fiduciary and corporate risks, including investment, operational, counterparty credit and enterprise risk. Representatives of RQA meet with the Board to discuss their analysis and methodologies, as well as specific risk topics such as operational and counterparty risks relating to the Funds. The Board, directly or through a committee, also reviews reports from, among others, management and the independent registered public accounting firm for the Trust, as appropriate, regarding risks faced by each Fund and management’s risk functions. The Board has appointed a Chief Compliance Officer who oversees the implementation and testing of the Trust's compliance program, including assessments by independent third parties, and reports to the Board regarding compliance matters for the Trust and its principal service providers. In testing and maintaining the compliance program, the Chief Compliance Officer (and his or her delegates) assesses key compliance risks affecting each Fund, and addresses them in periodic reports to the Board. In addition, the Audit Committee meets with both the Funds' independent registered public accounting firm and BFA’s internal audit group to review risk controls in place that support each Fund as well as test results. Board oversight of risk is also performed as needed between meetings through communications between BFA and the Board. The Independent Trustees have engaged independent legal counsel to assist them in performing their oversight responsibilities. From time to time, the Board may modify the manner in which it conducts risk oversight. The Board’s oversight role does not make it a guarantor of the Funds' investment performance or other activities.

Each Independent Trustee serves on the 15(c) Committee. The Chair of the 15(c) Committee is Drew E. Lawton. The principal responsibilities of the 15(c) Committee are to support, oversee and organize on behalf of the Board the process for the annual review and renewal of the Trust's advisory and sub-advisory agreements. These responsibilities include: (i) meeting with BlackRock, Inc. in advance of the Board meeting at which the Trust's advisory and sub-advisory agreements are to be considered to discuss generally the process for providing requested information to the Board and the format in which information will be provided; and (ii) considering and discussing with BlackRock, Inc. such other matters and information as may be necessary and appropriate for the Board to evaluate the investment advisory and sub-advisory agreements of the Trust. The 15(c) Committee met two times during the fiscal year ended March 31, 2018.

The members of the Risk Committee are Jane D. Carlin (Chair), Charles A. Hurty, Drew E. Lawton and John E. Martinez, each of whom is an Independent Trustee. The principal responsibility of the Risk Committee is to consider and organize on behalf of the Board risk related matters of the Funds so the Board may most effectively structure itself to oversee them. The Risk Committee commenced on January 1, 2016. The Risk Committee met five times during the fiscal year ended March 31, 2018.

As the Chair of the Board, Cecilia H. Herbert may serve as an ex-officio member of each Committee.

Potential Conflicts of Interest. The PNC Financial Services Group, Inc. (“PNC”) has a significant economic interest in BlackRock, Inc., the parent of BFA, the Funds' investment adviser. BlackRock, Inc. and PNC are considered to be affiliated persons of one another under the 1940 Act. Certain activities of BFA, BlackRock, Inc. and their affiliates (collectively, “BlackRock”) and PNC and its affiliates (collectively, “PNC” and together with BlackRock, “Affiliates”), with respect to the Funds and/or other accounts managed by BlackRock or PNC, may give rise to actual or perceived conflicts of interest such as those described below.

BlackRock is one of the world's largest asset management firms. PNC is a diversified financial services organization spanning the retail, business and corporate markets. BlackRock, PNC and their respective affiliates (including, for these purposes, their directors, partners, trustees, managing members, officers and employees), including the entities and personnel who may be involved in the investment activities and business operations of a Fund, are engaged worldwide in businesses, including managing equities, fixed-income securities, cash and alternative investments, and banking and other financial services, and have interests other than that of managing a Fund. These are considerations of which investors in a Fund should be aware, and which may cause conflicts of interest that could disadvantage a Fund and its shareholders. These businesses and interests include potential multiple advisory, transactional, financial and other relationships with, or interests in, companies and interests in securities or other instruments that may be purchased or sold by a Fund.

BlackRock and the other Affiliates have proprietary interests in, and may manage or advise with respect to, accounts or funds (including separate accounts and other funds and collective investment vehicles) that have investment objectives similar to those of a Fund and/or that engage in transactions in the same types of securities, currencies and instruments as a Fund. One or more Affiliates are also major participants in the global currency, equities, swap and fixed-income markets, in each case, for the accounts of customers and, in some cases, on a proprietary basis. As such, one or more Affiliates are or may be actively engaged in transactions in the same securities, currencies, and instruments in which a Fund invests. Such activities could affect the prices and availability of the securities, currencies, and instruments in which a Fund invests, which could have an adverse impact on a Fund's performance. Such transactions, particularly in respect of most proprietary accounts or client accounts, will be executed independently of a Fund's transactions and thus at prices or rates that may be more or less favorable than those obtained by a Fund.

When BlackRock and the other Affiliates seek to purchase or sell the same assets for their managed accounts, including a Fund, the assets actually purchased or sold may be allocated among the accounts on a basis determined in their good faith discretion to be equitable. In some cases, this system may adversely affect the size or price of the assets purchased or sold for a Fund. In addition, transactions in investments by one or more other accounts managed by BlackRock or the other Affiliates may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of a Fund, particularly, but not limited to, with respect to small-capitalization, emerging market or less liquid strategies. This may occur when investment decisions regarding a Fund are based on research or other information that is also used to support decisions for other accounts. When BlackRock or the other Affiliates implement a portfolio decision or strategy on behalf of another account ahead of, or contemporaneously with, similar decisions or strategies for a Fund, market impact, liquidity constraints, or other factors could result in the Fund receiving less favorable trading results and the costs of implementing such decisions or strategies could be increased or the Fund could otherwise be disadvantaged. BlackRock or the other Affiliates may, in certain cases, elect to implement internal policies and procedures designed to limit such consequences, which may cause a Fund to be unable to engage in certain activities, including purchasing or disposing of securities, when it might otherwise be desirable for it to do so.

Conflicts may also arise because portfolio decisions regarding a Fund may benefit other accounts managed by BlackRock or the other Affiliates. For example, the sale of a long position or establishment of a short position by a Fund may impair the price of the same security sold short by (and therefore benefit) one or more Affiliates or their other accounts or funds, and the purchase of a security or covering of a short position in a security by a Fund may increase the price of the same security held by (and therefore benefit) one or more Affiliates or their other accounts or funds.

In certain circumstances, BlackRock, on behalf of a Fund, may seek to buy from or sell securities to another fund or account advised by BlackRock or an Affiliate. BlackRock may (but is not required to) effect purchases and sales between BlackRock clients or clients of Affiliates (“cross trades”), including a Fund, if BlackRock believes such transactions are appropriate based on each party's investment objectives and guidelines, subject to applicable law and regulation. There may be potential conflicts of interest or regulatory issues relating to these transactions which could limit BlackRock’s decision to engage in these transactions for a Fund. BlackRock may have a potentially conflicting division of loyalties and responsibilities to the parties in such transactions. On any occasion when a Fund participates in a cross trade, BlackRock will comply with procedures adopted under applicable rules and SEC guidance.

BlackRock and the other Affiliates and their clients may pursue or enforce rights with respect to an issuer in which a Fund has invested, and those activities may have an adverse effect on the Fund. As a result, prices, availability, liquidity and terms of a Fund's investments may be negatively impacted by the activities of BlackRock or the other Affiliates or their clients, and transactions for the Fund may be impaired or effected at prices or terms that may be less favorable than would otherwise have been the case.

The results of a Fund’s investment activities may differ significantly from the results achieved by BlackRock and the other Affiliates for their proprietary accounts or other accounts (including investment companies or collective investment vehicles) managed or advised by them. It is possible that one or more Affiliate-managed accounts and such other accounts will achieve investment results that are substantially more or less favorable than the results achieved by a Fund. Moreover, it is possible that a Fund will sustain losses during periods in which one or more Affiliates or Affiliate-managed accounts achieve significant profits on their trading for proprietary or other accounts. The opposite result is also possible.

From time to time, a Fund may be restricted from purchasing or selling securities, or from engaging in other investment activities because of regulatory, legal or contractual requirements applicable to BlackRock or one or more Affiliates or other accounts managed or advised by BlackRock or the other Affiliates for clients worldwide, and/or the internal policies of BlackRock and the other Affiliates designed to comply with such requirements. As a result, there may be periods, for example, when BlackRock and/or one or more Affiliates will not initiate or recommend certain types of transactions in certain securities or instruments with respect to which BlackRock and/or one or more Affiliates are performing services or when position limits have been reached. For example, the investment activities of one or more Affiliates for their proprietary accounts and accounts under their management may limit the investment opportunities for a Fund in certain emerging and other markets in which limitations are imposed upon the amount of investment, in the aggregate or in individual issuers, by affiliated foreign investors.

In connection with its management of a Fund, BlackRock may have access to certain fundamental analysis and proprietary technical models developed by one or more Affiliates. BlackRock will not be under any obligation, however, to effect transactions on behalf of a Fund in accordance with such analysis and models. In addition, neither BlackRock nor any of the other Affiliates will have any obligation to make available any information regarding their proprietary activities or strategies, or the activities or strategies used for other accounts managed by them, for the benefit of the management of a Fund and it is not anticipated that BlackRock will have access to such information for the purpose of managing the Fund. The proprietary activities or portfolio strategies of BlackRock and the other Affiliates, or the activities or strategies used for accounts managed by them or other customer accounts could conflict with the transactions and strategies employed by BlackRock in managing a Fund.

A Fund may be included in investment models developed by BlackRock and the other Affiliates for use by clients and financial advisors. The price, availability and liquidity of a Fund may be impacted by purchases and redemptions of a Fund by model-driven investment portfolios.

BlackRock may enter into transactions and invest in securities, instruments and currencies on behalf of a Fund in which clients of BlackRock or the other Affiliates, or, to the extent permitted by the SEC and applicable law, BlackRock or another Affiliate, serves as the counterparty, principal or issuer. In such cases, such party's interests in the transaction will be adverse to the interests of the Fund, and such party may have no incentive to assure that the Fund obtains the best possible prices or terms in connection with the transactions. In addition, the purchase, holding and sale of such investments by a Fund may enhance the profitability of BlackRock or the other Affiliates. One or more Affiliates may also create, write or issue derivatives for their clients, the underlying securities, currencies or instruments of which may be those in which a Fund invests or which may be based on the performance of the Fund. A Fund may, subject to applicable law, purchase investments that are the subject of an underwriting or other distribution by one or more Affiliates and may also enter into transactions with other clients of an Affiliate where such other clients have interests adverse to those of the Fund.

At times, these activities may cause departments of BlackRock or the other Affiliates to give advice to clients that may cause these clients to take actions adverse to the interests of a Fund. To the extent affiliated transactions are permitted, a Fund will deal with BlackRock and the other Affiliates (except with respect to BFA or affiliated sub-advisers of a Fund, as applicable) on an arms-length basis.

To the extent authorized by applicable law, one or more Affiliates may act as broker, dealer, agent, lender or adviser or in other commercial capacities for a Fund. It is anticipated that the commissions, markups, markdowns, financial advisory fees, underwriting and placement fees, sales fees, financing and commitment fees, brokerage fees, other fees, compensation or profits, rates, terms and conditions charged by an Affiliate will be in its view commercially reasonable, although each Affiliate,

including its sales personnel, will have an interest in obtaining fees and other amounts that are favorable to the Affiliate and such sales personnel, which may have an adverse effect on the Funds.

Subject to applicable law, the Affiliates (and their personnel and other distributors) will be entitled to retain fees and other amounts that they receive in connection with their service to the Funds as broker, dealer, agent, lender, adviser or in other commercial capacities. No accounting to a Fund or its shareholders will be required, and no fees or other compensation payable by a Fund or its shareholders will be reduced by reason of receipt by an Affiliate of any such fees or other amounts.

When an Affiliate acts as broker, dealer, agent, adviser or in other commercial capacities in relation to the Funds, the Affiliate may take commercial steps in its own interests, which may have an adverse effect on the Funds. A Fund will be required to establish business relationships with its counterparties based on the Fund's own credit standing. Neither BlackRock nor any of the Affiliates will have any obligation to allow their credit to be used in connection with a Fund's establishment of its business relationships, nor is it expected that the Fund's counterparties will rely on the credit of BlackRock or any of the other Affiliates in evaluating the Fund's creditworthiness.

Lending on behalf of a Fund is done by BTC pursuant to SEC exemptive relief, enabling BTC to act as securities lending agent to, and receive a share of securities lending revenues from, a Fund. An Affiliate will also receive compensation for managing the reinvestment of the cash collateral from securities lending. There are potential conflicts of interest in managing a securities lending program, including but not limited to: (i) BTC as securities lending agent may have an incentive to increase or decrease the amount of securities on loan or to lend particular securities in order to generate additional risk-adjusted revenue for BTC and its affiliates; and (ii) BTC as securities lending agent may have an incentive to allocate loans to clients that would provide more revenue to BlackRock. As described further below, BlackRock seeks to mitigate this conflict by providing its securities lending clients with equal lending opportunities over time in order to approximate pro-rata allocation.

Purchases and sales of securities and other assets for a Fund may be bunched or aggregated with orders for other BlackRock client and fund accounts, including with accounts that pay different transaction costs due to the fact that they have different research payment arrangements. BlackRock, however, is not required to bunch or aggregate orders if portfolio management decisions for different accounts or funds are made separately, or if it determines that bunching or aggregating is not practicable or required, is not in the best interest of a Fund, or in cases involving client direction.

the Funds. In addition, under certain circumstances, the Funds will not be charged the same commission or commission equivalent rates in connection with a bunched or aggregated order.

BlackRock may select brokers (including, without limitation, Affiliates, to the extent permitted by applicable law) that furnish BlackRock, the Funds, other BlackRock client accounts or other Affiliates or personnel, directly or through correspondent relationships, with research or other appropriate services which provide, in BlackRock's view, appropriate assistance to BlackRock in the investment decision-making process (including with respect to futures, fixed-price offerings and OTC transactions). Such research or other services may include, to the extent permitted by law, research reports on companies, industries and securities; economic and financial data; financial publications; proxy analysis; trade industry seminars; computer data bases; research-oriented software and other services and products. Research or other services obtained in this manner may be used in servicing other BlackRock client accounts, including in connection with BlackRock client accounts other than those that pay commissions to the broker relating to the research or other service arrangements. Such products and services may disproportionately benefit other BlackRock client accounts relative to the Funds based on the amount of brokerage commissions paid by the Funds and such other BlackRock client accounts. For example, research or other services that are paid for through one client's commissions may not be used in managing that client's account. In addition, other BlackRock client accounts may receive the benefit, including disproportionate benefits, of economies of scale or price discounts in connection with products and services that may be provided to the Funds and to such other BlackRock client accounts. To the extent that BlackRock uses soft dollars, it will not have to pay for those products and services itself.

BlackRock does not currently enter into arrangements to use the Funds' assets for, or participate in, soft dollars, although BlackRock may receive research that is bundled with the trade execution, clearing, and/or settlement services provided by a particular broker-dealer. To the extent that BlackRock receives research on this basis, many of the same conflicts related to traditional soft dollars may exist. For example, the research effectively will be paid by client commissions that also will be used to pay for the execution, clearing, and settlement services provided by the broker-dealer and will not be paid by BlackRock.

BlackRock may utilize certain electronic crossing networks (“ECNs”) (including, without limitation, ECNs in which BlackRock or the other Affiliates have an investment or other interest, to the extent permitted by applicable law) in executing client securities transactions for certain types of securities. These ECNs may charge fees for their services, including access fees and transaction fees. The transaction fees, which are similar to commissions or markups/markdowns, will generally be charged to clients and, like commissions and markups/markdowns, would generally be included in the cost of the securities purchased. Access fees may be paid by BlackRock even though incurred in connection with executing transactions on behalf of clients, including the Funds. In certain circumstances, ECNs may offer volume discounts that will reduce the access fees typically paid by BlackRock. BlackRock will only utilize ECNs consistent with its obligation to seek to obtain best execution in client transactions.

BlackRock has adopted policies and procedures designed to prevent conflicts of interest from influencing proxy voting decisions that it makes on behalf of advisory clients, including the Funds, and to help ensure that such decisions are made in accordance with BlackRock's fiduciary obligations to its clients. Nevertheless, notwithstanding such proxy voting policies and procedures, actual proxy voting decisions of BlackRock may have the effect of favoring the interests of other clients or businesses of other divisions or units of BlackRock and/or the other Affiliates, provided that BlackRock believes such voting decisions to be in accordance with its fiduciary obligations. For a more detailed discussion of these policies and procedures, see the Proxy Voting Policy section of this SAI.

other Affiliates reserve the right, subject to compliance with applicable law, to sell into the market or redeem in Creation Units through an Authorized Participant at any time some or all of the shares of a Fund acquired for their own accounts. A large sale or redemption of shares of a Fund by BlackRock or the other Affiliates could significantly reduce the asset size of the Fund, which might have an adverse effect on the Fund's liquidity, investment flexibility, portfolio diversification, expense ratio or ability to comply with the listing requirements for the Fund. BlackRock seeks to consider the effect of redemptions on a Fund and other shareholders in deciding whether to redeem its shares but is not obligated to do so and may elect not to do so.

It is possible that a Fund may invest in securities of, or engage in transactions with, companies with which an Affiliate has developed or is trying to develop investment banking relationships as well as securities of entities in which BlackRock or the other Affiliates has significant debt or equity investments or other interests or in which an Affiliate makes a market. A Fund also may invest in securities of, or engage in transactions with, companies to which an Affiliate provides or may in the future provide research coverage. Such investments or transactions could cause conflicts between the interests of a Fund and the interests of BlackRock, other clients of BlackRock or the other Affiliates. In making investment decisions for a Fund, BlackRock is not permitted to obtain or use material non-public information acquired by any division, department or Affiliate of BlackRock in the course of these activities. In addition, from time to time, the activities of an Affiliate may limit a Fund's flexibility in purchases and sales of securities. When an Affiliate is engaged in an underwriting or other distribution of securities of an entity, BlackRock may be prohibited from purchasing or recommending the purchase of certain securities of that entity for a Fund. As indicated below, BlackRock or the other Affiliates may engage in transactions with companies in which BlackRock-advised funds or other clients of BlackRock or of an Affiliate have an investment.

BlackRock and the other Affiliates, their personnel and other financial service providers may have interests in promoting sales of a Fund. With respect to BlackRock and the other Affiliates and their personnel, the remuneration and profitability relating to services to and sales of a Fund or other products may be greater than remuneration and profitability relating to services to and sales of certain funds or other products that might be provided or offered. BlackRock and the other Affiliates and their sales personnel may directly or indirectly receive a portion of the fees and commissions charged to a Fund or its shareholders. BlackRock and its advisory or other personnel may also benefit from increased amounts of assets under management. Fees and commissions may also be higher than for other products or services, and the remuneration and profitability to BlackRock or the other Affiliates and such personnel resulting from transactions on behalf of or management of a Fund may be greater than the remuneration and profitability resulting from other funds or products.

Third parties, including service providers to BlackRock or a Fund, may sponsor events (including, but not limited to, marketing and promotional activities and presentations, educational training programs and conferences) for registered representatives, other professionals and individual investors. There is a potential conflict of interest as such sponsorships may defray the costs of such activities to BlackRock, and may provide an incentive to BlackRock to retain such third parties to provide services to a Fund.

quotes or other data sources unavailable to the Fund's pricing vendors. While BlackRock will generally communicate its valuation information or determinations to a Fund's pricing vendors and/or fund accountants, there may be instances where the Fund's pricing vendors or fund accountants assign a different valuation to a security or other investment than the valuation for such security or investment determined or recommended by BlackRock.

As disclosed in more detail in the Determination of Net Asset Value section of each Fund’s Prospectus and this SAI, when market quotations are not readily available or are believed by BlackRock to be unreliable, a Fund’s investments are valued at fair value by BlackRock in accordance with procedures adopted by the Board. When determining “fair value price,” BlackRock seeks to determine the price that a Fund might reasonably expect to receive from the current sale of that asset or liability in an arm’s-length transaction. The price generally may not be determined based on what a Fund might expect to receive for selling an asset or liability at a later time or if it holds the asset or liability to maturity. While fair value determinations will be based upon all available factors that BlackRock deems relevant at the time of the determination, and may be based on analytical values determined by BlackRock using proprietary or third-party valuation models, fair value represents only a good faith approximation of the value of an asset or liability. The fair value of one or more assets or liabilities may not, in retrospect, be the price at which those assets or liabilities could have been sold during the period in which the particular fair values were used in determining a Fund’s net asset value. As a result, a Fund’s sale or redemption of its shares at net asset value, at a time when a holding or holdings are valued by BlackRock (pursuant to Board-adopted procedures) at fair value, may have the effect of diluting or increasing the economic interest of existing shareholders and may affect the amount of revenue received by BlackRock with respect to services for which it receives an asset-based fee.

To the extent permitted by applicable law, a Fund may invest all or some of its short-term cash investments in any money market fund or similarly-managed private fund advised or managed by BlackRock. In connection with any such investments, a Fund, to the extent permitted by the 1940 Act, may pay its share of expenses of a money market fund or other similarly-managed private fund in which it invests, which may result in a Fund bearing some additional expenses.

BlackRock and the other Affiliates and their directors, officers and employees, may buy and sell securities or other investments for their own accounts and may have conflicts of interest with respect to investments made on behalf of a Fund. As a result of differing trading and investment strategies or constraints, positions may be taken by directors, officers, employees and Affiliates that are the same, different from or made at different times than positions taken for the Fund. To lessen the possibility that a Fund will be adversely affected by this personal trading, each Fund, BFA and BlackRock, Inc. have each adopted a code of ethics in compliance with Section 17(j) of the 1940 Act that restricts securities trading in the personal accounts of investment professionals and others who normally come into possession of information regarding a Fund's portfolio transactions. Each code of ethics is available by contacting BlackRock or by accessing the EDGAR Database on the SEC's Internet site at http://www.sec.gov, and copies may be obtained, after paying a duplicating fee, by e-mail at publicinfo@sec.gov or by writing the SEC's Public Reference Room, Washington, DC 20549-1520. Information about accessing documents on the SEC’s website may be obtained by calling the SEC at (800) SEC-0330.

BlackRock and the other Affiliates will not purchase securities or other property from, or sell securities or other property to, a Fund, except that a Fund may in accordance with rules or guidance adopted under the 1940 Act engage in transactions with accounts that are affiliated with a Fund as a result of common officers, directors, or investment advisers or pursuant to exemptive orders granted to the Funds and/or BlackRock by the SEC. These transactions would be effected in circumstances in which BlackRock determined that it would be appropriate for a Fund to purchase and another client of BlackRock to sell, or the Fund to sell and another client of BlackRock to purchase, the same security or instrument on the same day. From time to time, the activities of a Fund may be restricted because of regulatory requirements applicable to BlackRock or the other Affiliates and/or BlackRock's internal policies designed to comply with, limit the applicability of, or otherwise relate to such requirements. A client not advised by BlackRock would not be subject to some of those considerations. There may be periods when BlackRock may not initiate or recommend certain types of transactions, or may otherwise restrict or limit their advice in certain securities or instruments issued by or related to companies for which an Affiliate is performing investment banking, market making, advisory or other services or has proprietary positions. For example, when an Affiliate is engaged in an underwriting or other distribution of securities of, or advisory services for, a company, the Funds may be prohibited from or limited in purchasing or selling securities of that company. In addition, when BlackRock provides advisory or risk management services for a company, BlackRock may be prohibited from or limited in purchasing or selling securities of that company on behalf of a Fund, particularly where such services result in BlackRock obtaining material non-public information about the company (e.g., in connection with participation in a creditors’ committee). Similar situations could arise if personnel of BlackRock or the other Affiliates serve as directors of companies the securities of which a Fund wishes to purchase or sell. However, if permitted by applicable law, and where consistent with BlackRock’s policies and procedures

(including the necessary implementation of appropriate information barriers), the Funds may purchase securities or instruments that are issued by such companies, are the subject of an underwriting, distribution or advisory assignment by an Affiliate, or are the subject of an advisory or risk management assignment by BlackRock, or where personnel of BlackRock or the other Affiliates are directors or officers of the issuer.

The investment activities of one or more Affiliates for their proprietary accounts and for client accounts may also limit the investment strategies and rights of the Funds. For example, in certain circumstances where the Funds invest in securities issued by companies that operate in certain regulated industries or in certain emerging or international markets, or are subject to corporate or regulatory ownership restrictions, or invest in certain futures or other derivative transactions, there may be limits on the aggregate amount invested by Affiliates (including BlackRock) for their proprietary accounts and for client accounts (including the Funds) that may not be exceeded without the grant of a license or other regulatory or corporate consent or, if exceeded, may cause BlackRock, the Funds or other client accounts to suffer disadvantages or business restrictions.

If certain aggregate ownership thresholds are reached either through the actions of BlackRock or a Fund or as a result of third-party transactions, the ability of BlackRock, on behalf of clients (including the Funds), to purchase or dispose of investments, or exercise rights or undertake business transactions, may be restricted by regulation or otherwise impaired. As a result, BlackRock, on behalf of clients (including the Funds), may limit purchases, sell existing investments, or otherwise restrict, forgo or limit the exercise of rights (including transferring, outsourcing or limiting voting rights or forgoing the right to receive dividends) when BlackRock, in its sole discretion, deems it appropriate in light of potential regulatory or other restrictions on ownership or other consequences resulting from reaching investment thresholds.

In those circumstances where ownership thresholds or limitations must be observed, BlackRock seeks to allocate limited investment opportunities equitably among clients (including the Funds), taking into consideration benchmark weight and investment strategy. BlackRock has adopted certain controls designed to prevent the occurrence of a breach of any applicable ownership threshold or limits, including, for example, when ownership in certain securities nears an applicable threshold, BlackRock may remove such securities from the list of Deposit Securities to be delivered to the Fund in connection with purchases of Creation Units of such Fund and may limit purchases in such securities to the issuer's weighting in the applicable benchmark used by BlackRock to manage such Fund. If client (including Fund) holdings of an issuer exceed an applicable threshold and BlackRock is unable to obtain relief to enable the continued holding of such investments, it may be necessary to sell down these positions to meet the applicable limitations. In these cases, benchmark overweight positions will be sold prior to benchmark positions being reduced to meet applicable limitations.

BlackRock and the other Affiliates may not serve as Authorized Participants in the creation and redemption of iShares ETFs, but may serve as authorized participants of third-party ETFs.

BlackRock may enter into contractual arrangements with third-party service providers to a Fund (e.g., custodians and administrators) pursuant to which BlackRock receives fee discounts or concessions in recognition of BlackRock’s overall relationship with such service providers. To the extent that BlackRock is responsible for paying these service providers out of its management fee, the benefits of any such fee discounts or concessions may accrue, in whole or in part, to BlackRock.

BlackRock or the other Affiliates own or have an ownership interest in certain trading, portfolio management, operations and/or information systems used by Fund service providers. These systems are, or will be, used by a Fund service provider in connection with the provision of services to accounts managed by BlackRock and funds managed and sponsored by BlackRock, including the Funds, that engage the service provider (typically the custodian). A Fund’s service provider remunerates BlackRock or the other Affiliates for the use of the systems. A Fund service provider’s payments to BlackRock or the other Affiliates for the use of these systems may enhance the profitability of BlackRock and the other Affiliates. BlackRock’s or the other Affiliates’ receipt of fees from a service provider in connection with the use of systems provided by BlackRock or the other Affiliates may create an incentive for BlackRock to recommend that a Fund enter into or renew an arrangement with the service provider.

Present and future activities of BlackRock and the other Affiliates, including BFA, in addition to those described in this section, may give rise to additional conflicts of interest.

Investment Advisory, Administrative and Distribution Services

Investment Adviser. BFA serves as investment adviser to each Fund pursuant to an investment advisory agreement between the Trust, on behalf of each Fund, and BFA. BFA is a California corporation indirectly owned by BlackRock, Inc. and is registered as an investment adviser under the Investment Advisers Act of 1940, as amended. Under the investment advisory agreement, BFA, subject to the supervision of the Board and in conformity with the stated investment policies of each Fund, manages and administers the Trust and the investment of each Fund’s assets. BFA is responsible for placing purchase and sale orders and providing continuous supervision of the investment portfolio of each Fund.

Pursuant to the investment advisory agreement, BFA may, from time to time, in its sole discretion and to the extent permitted by applicable law, appoint one or more sub-advisers, including, without limitation, affiliates of BFA, to perform investment advisory or other services with respect to a Fund. In addition, BFA may delegate certain of its investment advisory functions under the investment advisory agreement to one or more of its affiliates to the extent permitted by applicable law. BFA may terminate any or all sub-advisers or such delegation arrangements in its sole discretion upon appropriate notice at any time to the extent permitted by applicable law.

BFA is responsible, under the investment advisory agreement, for substantially all expenses of the Funds, including the cost of transfer agency, custody, fund administration, legal, audit and other services. BFA is not responsible for, and the Funds will bear, the management fees, interest expenses, taxes, expenses incurred with respect to the acquisition and disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions, distribution fees or expenses, litigation expenses and any extraordinary expenses (as determined by a majority of the Independent Trustees).

The following table sets forth the management fee at the annual rate (as a percentage of each Fund's average daily net assets) BFA received from each Fund for the fiscal year ended March 31, 2018 and the management fees (net of waivers) each Fund paid BFA for the fiscal years noted:

Fund	Management Fee for the Fiscal Year Ended March 31, 2018	Fund Inception Date	Management Fees Paid Net of Waivers for Fiscal Year Ended March 31, 2018	Management Fees Paid Net of Waivers for Fiscal Year Ended March 31, 2017	Management Fees Paid Net of Waivers for Fiscal Year Ended March 31, 2016
iShares iBonds Sep 2018 Term Muni Bond ETF¹	0.18%	03/19/13	$363,640	$ 255,615	$170,970
iShares iBonds Sep 2019 Term Muni Bond ETF²	0.18%	02/04/14	381,590	225,157	129,618
iShares iBonds Sep 2020 Term Muni Bond ETF³	0.18%	08/12/14	387,439	215,867	96,402

Prior to August 1, 2016, for the iShares iBonds Sep 2018 Term Muni Bond ETF, BFA contractually agreed to waive a portion of its management fees in order to limit the Total Annual Fund Operating Expenses to 0.18% of the average daily net assets through the termination date of the Fund, on or about September 1, 2018. For the fiscal years ended March 31, 2018, March 31, 2017 and March 31, 2016, BFA waived $0, $47,741and $114,384 of its management fees, respectively. The contractual waiver was discontinued on August 1, 2016.

Prior to August 1, 2016, for the iShares iBonds Sep 2019 Term Muni Bond ETF, BFA contractually agreed to waive a portion of its management fees in order to limit the Total Annual Fund Operating Expenses to 0.18% of the average daily net assets through the termination date of the Fund, on or about September 1, 2019. For the fiscal years ended March 31, 2018, March 31, 2017 and March 31, 2016, BFA waived $0, $42,256 and $86,937 of its management fees, respectively. The contractual waiver was discontinued on August 1, 2016.

Prior to August 1, 2016, for the iShares iBonds Sep 2020 Term Muni Bond ETF, BFA contractually agreed to waive a portion of its management fees in order to limit the Total Annual Fund Operating Expenses to 0.18% of the average daily net assets through the termination date of the Fund, on or about September 1, 2020. For the fiscal years ended March 31, 2018, March 31, 2017 and March 31, 2016, BFA waived $0, $37,154 and $64,729 of its management fees, respectively. The contractual waiver was discontinued on August 1, 2016.

The investment advisory agreement with respect to each Fund continues in effect for two years from its effective date, and thereafter is subject to annual approval by (i) the Board, or (ii) the vote of a majority of the outstanding voting securities (as defined in the 1940 Act) of the applicable Fund, provided that in either event such continuance also is approved by a majority of the Board members who are not interested persons (as defined in the 1940 Act) of the applicable Fund, by a vote cast in person at a meeting called for the purpose of voting on such approval.

The investment advisory agreement with respect to each Fund is terminable without penalty, on 60 days’ notice, by the Board or by a vote of the holders of a majority of the applicable Fund’s outstanding voting securities (as defined in the 1940 Act). The investment advisory agreement is also terminable upon 60 days’ notice by BFA and will terminate automatically in the event of its assignment (as defined in the 1940 Act).

Portfolio Managers. As of March 31, 2018, the individuals named as Portfolio Managers in each Fund’s Prospectus were also primarily responsible for the day-to-day management of other iShares funds and certain other types of portfolios and/or accounts as follows:

James Mauro
Types of Accounts	Number	Total Assets
Registered Investment Companies	82	$268,966,000,000
Other Pooled Investment Vehicles	8	27,710,000,000
Other Accounts	8	6,309,000,000

Scott Radell
Types of Accounts	Number	Total Assets
Registered Investment Companies	93	$278,112,000,000
Other Pooled Investment Vehicles	8	13,248,000,000
Other Accounts	11	6,312,000,000

Each of the portfolios or accounts for which the Portfolio Managers are primarily responsible for the day-to-day management seeks to track the rate of return, risk profile and other characteristics of independent third-party indexes by either replicating the same combination of securities and other financial instruments that compose those indexes or through a representative sampling of the securities and other financial instruments that compose those indexes based on objective criteria and data. Pursuant to BFA policy, investment opportunities are allocated equitably among the Funds and other portfolios and accounts. For example, under certain circumstances, an investment opportunity may be restricted due to limited supply in the market, legal constraints or other factors, in which event the investment opportunity will be allocated equitably among those portfolios and accounts, including the Funds, seeking such investment opportunity. As a consequence, from time to time the Funds may receive a smaller allocation of an investment opportunity than they would have if the Portfolio Managers and BFA and its affiliates did not manage other portfolios or accounts.

Like the Funds, the other portfolios or accounts for which the Portfolio Managers are primarily responsible for the day-to-day portfolio management generally pay an asset-based fee to BFA or its affiliates, as applicable, for its advisory services. One or more of those other portfolios or accounts, however, may pay BFA or its affiliates a performance-based fee in lieu of, or in addition to, an asset-based fee for its advisory services. A portfolio or account with a performance-based fee would pay BFA or its affiliates a portion of that portfolio's or account's gains, or would pay BFA or its affiliates more for its services than would otherwise be the case if BFA or its affiliates meets or exceeds specified performance targets. Performance-based fee arrangements could present an incentive for BFA or its affiliates to devote greater resources, and allocate more investment opportunities, to the portfolios or accounts that have those fee arrangements, relative to other portfolios or accounts, in order to earn larger fees. Although BFA and its affiliates have an obligation to allocate resources and opportunities equitably among portfolios and accounts and intends to do so, shareholders of the Funds should be aware that, as with any group of portfolios and accounts managed by an investment adviser and/or its affiliates pursuant to varying fee arrangements,

including performance-based fee arrangements, there is the potential for a conflict-of-interest, which may result in the Portfolio Managers' favoring those portfolios or accounts with performance-based fee arrangements.

The discussion below describes the Portfolio Managers' compensation as of March 31, 2018.

Portfolio Manager Compensation Overview

BlackRock, Inc.'s financial arrangements with its portfolio managers, its competitive compensation and its career path emphasis at all levels reflect the value senior management places on key resources. Compensation may include a variety of components and may vary from year to year based on a number of factors. The principal components of compensation include a base salary, a performance-based discretionary bonus, participation in various benefits programs and one or more of the incentive compensation programs established by BlackRock, Inc.

Base compensation. Generally, portfolio managers receive base compensation based on their position with the firm.

Other Compensation Benefits. In addition to base compensation and discretionary incentive compensation, portfolio managers may be eligible to receive or participate in one or more of the following:

to 50% of the first 8% of eligible pay contributed to the plan capped at $5,000 per year, and a company retirement contribution equal to 3-5% of eligible compensation up to the U.S. Internal Revenue Service (the “IRS”) limit ($275,000 for 2018). The RSP offers a range of investment options, including registered investment companies and collective investment funds managed by the firm. BlackRock, Inc. contributions follow the investment direction set by participants for their own contributions or, absent participant investment direction, are invested into an index target date fund that corresponds to, or is closest to, the year in which the participant attains age 65. The ESPP allows for investment in BlackRock, Inc. common stock at a 5% discount on the fair market value of the stock on the purchase date. Annual participation in the ESPP is limited to the purchase of 1,000 shares of common stock or a dollar value of $25,000 based on its fair market value on the Purchase Date. James Mauro and Scott Radell are each eligible to participate in these plans.

As of March 31, 2018, the Portfolio Managers did not beneficially own shares of the Funds.

Codes of Ethics. The Trust, BFA and the Distributor have adopted codes of ethics pursuant to Rule 17j-1 under the 1940 Act. The codes of ethics permit personnel subject to the codes of ethics to invest in securities, subject to certain limitations, including securities that may be purchased or held by the Funds. The codes of ethics are on public file with, and are available from, the SEC.

Anti-Money Laundering Requirements. The Funds are subject to the USA PATRIOT Act (the “Patriot Act”). The Patriot Act is intended to prevent the use of the U.S. financial system in furtherance of money laundering, terrorism or other illicit activities. Pursuant to requirements under the Patriot Act, a Fund may request information from Authorized Participants to enable it to form a reasonable belief that it knows the true identity of its Authorized Participants. This information will be used to verify the identity of Authorized Participants or, in some cases, the status of financial professionals; it will be used only for compliance with the requirements of the Patriot Act.

The Funds reserve the right to reject purchase orders from persons who have not submitted information sufficient to allow the Fund to verify their identity. Each Fund also reserves the right to redeem any amounts in a Fund from persons whose identity it is unable to verify on a timely basis. It is the Funds' policy to cooperate fully with appropriate regulators in any investigations conducted with respect to potential money laundering, terrorism or other illicit activities.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) serves as administrator, custodian and transfer agent for the Funds under the Master Services Agreement and related Service Schedule (the “Service Module”). State Street’s principal address is 1 Lincoln Street, Boston, MA 02111. Pursuant to the Service Module for Fund Administration and Accounting Services with the Trust, State Street provides necessary administrative, legal, tax and accounting and financial reporting services for the maintenance and operations of the Trust and each Fund. In addition, State Street makes available the office space, equipment, personnel and facilities required to provide such services. Pursuant to the Service Module for Custodial Services with the Trust, State Street maintains, in separate accounts, cash, securities and other assets of the Trust and each Fund, keeps all necessary accounts and records and provides other services. State Street is required, upon the order of the Trust, to deliver securities held by State Street and to make payments for securities purchased by the Trust for each Fund. State Street is authorized to appoint certain foreign custodians or foreign custody managers for Fund investments outside the U.S. Pursuant to the Service Module for Transfer Agency Services with the Trust, State Street acts as a transfer agent for each Fund’s authorized and issued shares of beneficial interest, and as dividend disbursing agent of the Trust. As compensation for these services, State Street receives certain out-of-pocket costs, transaction fees and asset-based fees which are accrued daily and paid monthly by BFA from its management fee.

The following table sets forth the administration, custodian and transfer agency expenses of each Fund paid by BFA to State Street for the fiscal years noted:

Distributor. The Distributor's principal address is 1 University Square Drive, Princeton, NJ 08540. Shares are continuously offered for sale by the Funds through the Distributor or its agent only in Creation Units, as described in the applicable Prospectus and below in the Creation and Redemption of Creation Units section of this SAI. Fund shares in amounts less than Creation Units are generally not distributed by the Distributor or its agent. The Distributor or its agent will arrange for the delivery of the applicable Prospectus and, upon request, this SAI to persons purchasing Creation Units and will maintain records of both orders placed with it or its agents and confirmations of acceptance furnished by it or its agents. The Distributor is a broker-dealer registered under the Securities Exchange Act of 1934, as amended (the “1934 Act”), and a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). The Distributor is also licensed as a broker-dealer in all 50 U.S. states, as well as in Puerto Rico, the U.S. Virgin Islands and the District of Columbia.

The Distribution Agreement for each Fund provides that it may be terminated at any time, without the payment of any penalty, on at least 60 days' prior written notice to the other party following (i) the vote of a majority of the Independent Trustees, or (ii) the vote of a majority of the outstanding voting securities (as defined in the 1940 Act) of the relevant Fund. The Distribution Agreement will terminate automatically in the event of its assignment (as defined in the 1940 Act).

Securities Lending. To the extent that a Fund engages in securities lending, each Fund conducts its securities lending pursuant to SEC exemptive relief, and BTC acts as securities lending agent for the Funds, subject to the overall supervision of BFA, pursuant to a written agreement (the “Securities Lending Agency Agreement”).

Each Fund retains a portion of the securities lending income and remits the remaining portion to BTC as compensation for its services as securities lending agent. Securities lending income is generally equal to the total of income earned from the reinvestment of cash collateral (and excludes collateral investment fees as defined below), and any fees or other payments to and from borrowers of securities. As securities lending agent, BTC bears all operational costs directly related to securities lending. Each Fund is responsible for fees in connection with the investment of cash collateral received for securities on loan in a money market fund managed by BFA (the “collateral investment fees”); however, BTC has agreed to reduce the amount of securities lending income it receives in order to effectively limit the collateral investment fees the Fund bears to an annual rate of 0.04%. Such money market fund shares will not be subject to a sales load, redemption fee, distribution fee or service fee.

Pursuant to the Securities Lending Agency Agreement:

(i) Fixed income funds, such as the Funds, retain 80% of securities lending income (which excludes collateral investment fees) and (ii) this amount can never be less than 70% of the sum of securities lending income plus collateral investment fees.

Under the securities lending program, the Funds are categorized into one of several specific asset classes. The determination of a Fund’s asset class category (fixed-income, domestic equity, international equity or fund-of-funds), each of which may be subject to a different fee arrangement, is based on a methodology agreed to by the Trust and BTC.

In addition, commencing the business day following the date that the aggregate securities lending income (which includes, for this purpose, collateral investment fees) earned across the Exchange-Traded Fund Complex (as defined under “Management—Trustees and Officers”) in a calendar year exceeds the aggregate securities lending income earned across the Exchange-Traded Fund Complex in calendar year 2013 (the Hurdle Date), each applicable fixed income fund, pursuant to the securities lending agreement, will receive for the remainder of that calendar year securities lending income as follows:

The services provided to the Funds by BTC in the most recent fiscal year ended March 31, 2018 primarily included the following:

(1) selecting borrowers from an approved list of borrowers and executing a securities lending agreement as agent on behalf of the Funds with each such borrower;

(2) negotiating the terms of securities loans, including the amount of fees;

(3) directing the delivery of loaned securities;

(4) monitoring the daily value of the loaned securities and directing the payment of additional collateral or the return of excess collateral, as necessary;

(5) investing cash collateral received in connection with any loaned securities;

(6) monitoring distributions on loaned securities (for example, interest and dividend activity);

(8) terminating securities loans and arranging for the return of loaned securities to the Funds at loan termination.

The following tables show the dollar amounts of income and fees/compensation related to the securities lending activities of each Fund during its most recent fiscal year ended March 31, 2018.

not from the assets of the Funds. Although a portion of BFA Entities’ revenue comes directly or indirectly in part from fees paid by the Funds, other iShares funds or exchange-traded products, these payments do not increase the price paid by investors for the purchase of shares of, or the cost of owning, the Funds, other iShares funds or exchange-traded products. BFA Entities make payments for Intermediaries’ participation in activities that are designed to make registered representatives, other professionals and individual investors more knowledgeable about exchange-traded products, including the Funds and other iShares funds, or for other activities, such as participation in marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems (“Education Costs”). BFA Entities also make payments to Intermediaries for certain printing, publishing and mailing costs or materials relating to the Funds, other iShares funds or exchange-traded products (“Publishing Costs”). In addition, BFA Entities make payments to Intermediaries that make shares of the Funds, other iShares funds or exchange-traded products available to their clients, develop new products that feature iShares or otherwise promote the Funds, other iShares funds and exchange-traded products. BFA Entities may also reimburse expenses or make payments from their own assets to Intermediaries or other persons in consideration of services or other activities that the BFA Entities believe may benefit the iShares business or facilitate investment in the Funds, other iShares funds or exchange-traded products. Payments of the type described above are sometimes referred to as revenue-sharing payments.

Payments to an Intermediary may be significant to the Intermediary, and amounts that Intermediaries pay to your salesperson or other investment professional may also be significant for your salesperson or other investment professional. Because an Intermediary may make decisions about which investment options it will recommend or make available to its clients or what services to provide for various products based on payments it receives or is eligible to receive, such payments may create conflicts of interest between the Intermediary and its clients and these financial incentives may cause the Intermediary to recommend the Funds, other iShares funds or exchange-traded products over other investments. The same conflicts of interest and financial incentives exist with respect to your salesperson or other investment professional if he or she receives similar payments from his or her Intermediary firm.

In addition to the payments described above, BFA Entities have developed proprietary tools, calculators and related interactive or digital content that is made available through the www.BlackRock.com website at no additional cost to Intermediaries. BlackRock may configure these tools and calculators and localizes the content for Intermediaries as part of its customary digital marketing support and promotion of the Funds, other iShares funds, exchange-traded products and BlackRock mutual funds.

Further, BFA Entities make Education Costs and Publishing Costs payments to other Intermediaries that are not listed above. BFA Entities may determine to make such payments based on any number of metrics. For example, BFA Entities may make payments at year-end or other intervals in a fixed amount, an amount based upon an Intermediary’s services at defined levels or an amount based on the Intermediary’s net sales of one or more iShares funds in a year or other period, any of which arrangements may include an agreed-upon minimum or maximum payment, or any combination of the foregoing. As of the date of this SAI, BFA anticipates that the payments paid by BFA Entities in connection with the Funds, iShares funds and exchange-traded products in general will be immaterial to BFA Entities in the aggregate for the next year. Please contact your salesperson or other investment professional for more information regarding any such payments or financial incentives his or her Intermediary firm may receive. Any payments made, or financial incentives offered, by the BFA Entities to an Intermediary may create the incentive for the Intermediary to encourage customers to buy shares of the Funds, other iShares funds or other exchange-traded products.

The Funds may participate in certain market maker incentive programs of a national securities exchange in which an affiliate of the Funds would pay a fee to the exchange used for the purpose of incentivizing one or more market makers in the securities of a Fund to enhance the liquidity and quality of the secondary market of securities of a Fund. The fee would then be credited by the exchange to one or more market makers that meet or exceed liquidity and market quality standards with respect to the securities of a Fund. Each market maker incentive program is subject to approval from the SEC. Any such fee payments made to an exchange will be made by an affiliate of a Fund solely for the benefit of a Fund and will not be paid from any Fund assets. Other funds managed by BFA may also participate in such programs.

Determination of Net Asset Value

Valuation of Shares. The NAV for each Fund is generally calculated as of the close of business on the NYSE (normally 4:00 p.m., Eastern time) on each business day the NYSE is open. Valuation of securities held by a Fund is as follows:

Equity Investments. Equity securities traded on a recognized securities exchange (e.g., NYSE), on separate trading boards of a securities exchange or through a market system that provides contemporaneous transaction pricing information (each, an “Exchange”) are valued using information obtained via independent pricing services, generally at the closing price on the Exchange on which the security is primarily traded, or if an Exchange closing price is not available, the last traded price on that Exchange prior to the time as of which a Fund’s assets or liabilities are valued. However, under certain circumstances, other means of determining current market value may be used. If an equity security is traded on more than one Exchange, the current market value of the security where it is primarily traded generally will be used. In the event that there are no sales involving an equity security held by a Fund on a day on which a Fund values such security, the prior day’s price will be used, unless, in accordance with valuation procedures approved by the Board (the “Valuation Procedures”), BlackRock determines in good faith that such prior day’s price no longer reflects the fair value of the security, in which case such asset would be treated as a Fair Value Asset (as defined below).

Fixed-Income Investments. Fixed-income securities for which market quotations are readily available are generally valued using such securities’ current market value. A Fund values fixed-income portfolio securities using the last available bid prices or current market quotations provided by dealers or prices (including evaluated prices) supplied by a Fund’s approved independent third-party pricing services, each in accordance with the Valuation Procedures. The pricing services may use matrix pricing or valuation models that utilize certain inputs and assumptions to derive values, including transaction data (e.g., recent representative bids and offers), credit quality information, perceived market movements, news, and other relevant information and by other methods, which may include consideration of: yields or prices of securities of comparable quality, coupon, maturity and type; indications as to values from dealers; general market conditions; and/or other factors and assumptions. Pricing services generally value fixed-income securities assuming orderly transactions of an institutional round lot size, but a Fund may hold or transact in such securities in smaller, odd lot sizes. Odd lots may trade at lower prices than institutional round lots. The amortized cost method of valuation may be used with respect to debt obligations with sixty days or less remaining to maturity unless BlackRock determines in good faith that such method does not represent fair value. Loan participation notes are generally valued at the mean of the last available bid prices from one or more brokers or dealers as obtained from independent third-party pricing services. Certain fixed-income investments, including asset-backed and mortgage-related securities, may be valued based on valuation models that consider the estimated cash flows of each tranche of the entity, establish a benchmark yield and develop an estimated tranche-specific spread to the benchmark yield based on the unique attributes of the tranche.

Options, Futures, Swaps and Other Derivatives. Exchange-traded equity options for which market quotations are readily available are valued at the mean of the last bid and ask prices as quoted on the Exchange or the board of trade on which such options are traded. In the event that there is no mean price available for an exchange traded equity option held by a Fund on a day on which a Fund values such option, the last bid (long positions) or ask (short positions) price, if available, will be used as the value of such option. If no such bid or ask price is available on a day on which a Fund values such option, the prior day’s price will be used, unless BlackRock determines in good faith that such prior day’s price no longer reflects the fair value of the option, in which case such option will be treated as a Fair Value Asset (as defined below). OTC derivatives are valued using the last available bid prices or current market quotations provided by dealers or prices (including evaluated prices) supplied by a Fund’s approved independent third-party pricing services, each in accordance with the Valuation Procedures. OTC derivatives may be valued using a mathematical model which may incorporate a number of market data factors. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their settle price as of the close of such exchanges. Swap agreements and other derivatives are generally valued daily based upon quotations from market makers or by a pricing service in accordance with the Valuation Procedures.

Underlying Funds. Shares of underlying ETFs will be valued at their most recent closing price on an Exchange. Shares of underlying money market funds will be valued at their NAV.

General Valuation Information. The price a Fund could receive upon the sale of any particular portfolio investment may differ from a Fund’s valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair valuation methodology or a price provided by an independent pricing service. As a result, the price received upon the sale of an investment may be less than the value ascribed by a Fund, and a Fund could realize a greater than expected loss or lesser than expected gain upon the sale of the investment. A Fund’s ability to value its investment may also be impacted by technological issues and/or errors by pricing services or other third-party service providers.

All cash, receivables and current payables are carried on a Fund’s books at their face value.

Prices obtained from independent third-party pricing services, broker-dealers or market makers to value a Fund’s securities and other assets and liabilities are based on information available at the time a Fund values its assets and liabilities. In the event that a pricing service quotation is revised or updated subsequent to the day on which a Fund valued such security or other asset or liability, the revised pricing service quotation generally will be applied prospectively. Such determination will be made considering pertinent facts and circumstances surrounding the revision.

In the event that application of the methods of valuation discussed above result in a price for a security which is deemed not to be representative of the fair market value of such security, the security will be valued by, under the direction of or in accordance with a method approved by the Board as reflecting fair value. All other assets and liabilities (including securities for which market quotations are not readily available) held by a Fund (including restricted securities) are valued at fair value as determined in good faith by the Board or by BlackRock (its delegate) pursuant to the Valuation Procedures. Any assets and liabilities that are denominated in a foreign currency are converted into U.S. dollars using prevailing market rates on the date of valuation as quoted by one or more data service providers.

Certain of the securities acquired by a Fund may be traded on foreign exchanges or OTC markets on days on which a Fund’s NAV is not calculated. In such cases, the NAV of a Fund’s shares may be significantly affected on days when Authorized Participants can neither purchase nor redeem shares of a Fund.

Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate a Fund’s NAV and the prices used in the Underlying Index, which, in turn, could result in a difference between a Fund’s performance and the performance of the Underlying Index.

where it varies significantly from a recent trade, or no longer reflects the fair value of the security or other asset or liability subsequent to the most recent market quotation), or where the security or other asset or liability is only thinly traded or due to the occurrence of a significant event subsequent to the most recent market quotation. For this purpose, a “significant event” is deemed to occur if BlackRock determines, in its reasonable business judgment, that an event has occurred after the close of trading for an asset or liability but prior to or at the time of pricing a Fund’s assets or liabilities, and that the event is likely to cause a material change to the closing market price of the assets or liabilities held by a Fund. Non-U.S. securities whose values are affected by volatility that occurs in the markets or in related or highly correlated assets (e.g., American Depositary Receipts, Global Depositary Receipts or ETFs that invest in components of the Underlying Index) on a trading day after the close of non-U.S. securities markets may be fair valued. On any day the NYSE is open and a foreign market or the primary exchange on which a foreign asset or liability is traded is closed, such asset or liability will be valued using the prior day’s price, provided that BlackRock is not aware of any significant event or other information that would cause such price to no longer reflect the fair value of the asset or liability, in which case such asset or liability would be treated as a Fair Value Asset.

BlackRock, with input from the BlackRock Investment Strategy Group, will submit its recommendations regarding the valuation and/or valuation methodologies for Fair Value Assets to BlackRock’s Valuation Committee. The BlackRock Valuation Committee may accept, modify or reject any recommendations. In addition, a Fund’s accounting agent periodically endeavors to confirm the prices it receives from all third-party pricing services, index providers and broker-dealers, and, with the assistance of BlackRock, to regularly evaluate the values assigned to the securities and other assets and liabilities of a Fund. The pricing of all Fair Value Assets is subsequently reported to and, where appropriate, ratified by the Board.

When determining the price for a Fair Value Asset, the BlackRock Valuation Committee (or BlackRock’s Pricing Group) will seek to determine the price that a Fund might reasonably expect to receive upon the current sale of that asset or liability in an arm’s-length transaction on the date on which the assets or liabilities are being valued, and does not seek to determine the price that a Fund might expect to receive for selling the asset, or the cost of extinguishing a liability, at a later time or if it holds the asset or liability to maturity. Fair value determinations will be based upon all available factors that the BlackRock Valuation Committee (or BlackRock’s Pricing Group) deems relevant at the time of the determination, and may be based on analytical values determined by BlackRock using proprietary or third-party valuation models.

Fair value represents a good faith approximation of the value of an asset or liability. When determining the fair value of an asset, one or more of a variety of fair valuation methodologies may be used (depending on certain factors, including the asset type). For example, the asset may be priced on the basis of the original cost of the investment or, alternatively, using proprietary or third-party models (including models that rely upon direct portfolio management pricing inputs and which reflect the significance attributed to the various factors and assumptions being considered). Prices of actual, executed or historical transactions in the relevant asset and/or liability (or related or comparable assets and/or liabilities) or, where appropriate, an appraisal by a third-party experienced in the valuation of similar assets and/or liabilities, may also be used as a basis for establishing the fair value of an asset or liability. The fair value of one or more assets or liabilities may not, in retrospect, be the price at which those assets or liabilities could have been sold during the period in which the particular fair values were used in determining a Fund’s NAV. As a result, a Fund’s sale or redemption of its shares at NAV, at a time when a holding or holdings are valued at fair value, may have the effect of diluting or increasing the economic interest of existing shareholders.

Each Fund’s annual audited financial statements, which are prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”), follow the requirements for valuation set forth in Financial Accounting Standards Board Accounting Standards Codification Topic 820, “Fair Value Measurements and Disclosures” (“ASC 820”), which defines and establishes a framework for measuring fair value under US GAAP and expands financial statement disclosure requirements relating to fair value measurements. Generally, ASC 820 and other accounting rules applicable to funds and various assets in which they invest are evolving. Such changes may adversely affect a Fund. For example, the evolution of rules governing the determination of the fair market value of assets or liabilities to the extent such rules become more stringent would tend to increase the cost and/or reduce the availability of third-party determinations of fair market value. This may in turn increase the costs associated with selling assets or affect their liquidity due to a Fund’s inability to obtain a third-party determination of fair market value.

Brokerage Transactions

Subject to policies established by the Board, BFA is primarily responsible for the execution of a Fund’s portfolio transactions and the allocation of brokerage. BFA does not execute transactions through any particular broker or dealer, but seeks to obtain the best net results for the Funds, taking into account such factors as price (including the applicable brokerage commission or dealer spread), size of order, difficulty of execution, operational facilities of the firm and the firm’s risk and skill in positioning blocks of securities. While BFA generally seeks reasonable trade execution costs, a Fund does not necessarily pay the lowest spread or commission available, and payment of the lowest commission or spread is not necessarily consistent with obtaining the best price and execution in particular transactions. Subject to applicable legal requirements, BFA may select a broker based partly upon brokerage or research services provided to BFA and its clients, including a Fund. In return for such services, BFA may cause a Fund to pay a higher commission than other brokers would charge if BFA determines in good faith that the commission is reasonable in relation to the services provided.

In selecting brokers or dealers to execute portfolio transactions, BFA seeks to obtain the best price and most favorable execution for a Fund and may take into account a variety of factors including: (i) the size, nature and character of the security or instrument being traded and the markets in which it is purchased or sold; (ii) the desired timing of the transaction; (iii) BFA’s knowledge of the expected commission rates and spreads currently available; (iv) the activity existing and expected in the market for the particular security or instrument, including any anticipated execution difficulties; (v) the full range of brokerage services provided; (vi) the broker’s or dealer’s capital; (vii) the quality of research and research services provided; (viii) the reasonableness of the commission, dealer spread or its equivalent for the specific transaction; and (ix) BFA’s knowledge of any actual or apparent operational problems of a broker or dealer. Brokers may also be selected because of their ability to handle special or difficult executions, such as may be involved in large block trades, less liquid securities, or other circumstances.

From time to time, a Fund may purchase new issues of securities in a fixed price offering. In these situations, the broker may be a member of the selling group that will, in addition to selling securities, provide BFA with research services. FINRA has adopted rules expressly permitting these types of arrangements under certain circumstances. Generally, the broker will provide research “credits” in these situations at a rate that is higher than that available for typical secondary market transactions. These arrangements may not fall within the safe harbor of Section 28(e).

OTC issues, including most fixed-income securities such as corporate debt and U.S. Government securities, are normally traded on a “net” basis without a stated commission, through dealers acting for their own account and not as brokers. The Funds will primarily engage in transactions with these dealers or deal directly with the issuer unless a better price or execution could be obtained by using a broker. Prices paid to a dealer with respect to both foreign and domestic securities will generally include a “spread,” which is the difference between the prices at which the dealer is willing to purchase and sell the specific security at the time, and includes the dealer’s normal profit.

Under the 1940 Act, persons affiliated with a Fund and persons who are affiliated with such affiliated persons are prohibited from dealing with the Fund as principal in the purchase and sale of securities unless a permissive order allowing such transactions is obtained from the SEC. Since transactions in the OTC market usually involve transactions with the dealers acting as principal for their own accounts, the Funds will not deal with affiliated persons and affiliated persons of such affiliated persons, including PNC and its affiliates, in connection with such transactions. The Funds will not purchase securities during the existence of any underwriting or selling group relating to such securities of which BFA, PNC, BRIL or any affiliated person (as defined in the 1940 Act) thereof is a member except pursuant to procedures adopted by the Board in accordance with Rule 10f-3 under the 1940 Act.

Purchases of money market instruments by the Funds are made from dealers, underwriters and issuers. The Funds do not currently expect to incur any brokerage commission expense on such transactions because money market instruments are generally traded on a “net” basis with dealers acting as principal for their own accounts without a stated commission. The price of the security, however, usually includes a profit to the dealer.

BFA may, from time to time, effect trades on behalf of and for the account of the Funds with brokers or dealers that are affiliated with BFA, in conformity with Rule 17e-1 under the 1940 Act and SEC rules and regulations. Under these provisions, any commissions paid to affiliated brokers or dealers must be reasonable and fair compared to the commissions charged by other brokers or dealers in comparable transactions.

Investment decisions for the Funds and for other investment accounts managed by BFA and the other Affiliates are made independently of each other in light of differing conditions. A variety of factors will be considered in making investment allocations. These factors include: (i) investment objectives or strategies for particular accounts, including sector, industry, country or region and capitalization weightings; (ii) tax considerations of an account; (iii) risk or investment concentration parameters for an account; (iv) supply or demand for a security at a given price level; (v) size of available investment; (vi) cash availability and liquidity requirements for accounts; (vii) regulatory restrictions; (viii) minimum investment size of an account; (ix) relative size of account; and (x) such other factors as may be approved by BlackRock’s general counsel. Moreover, investments may not be allocated to one client account over another based on any of the following considerations: (i) to favor one client account at the expense of another; (ii) to generate higher fees paid by one client account over another or to produce greater performance compensation to BlackRock; (iii) to develop or enhance a relationship with a client or prospective client; (iv) to compensate a client for past services or benefits rendered to BlackRock or to induce future services or benefits to be rendered to BlackRock; or (v) to manage or equalize investment performance among different client accounts. BFA and the other Affiliates may deal, trade and invest for their own respective accounts in the types of securities in which the Funds may invest.

Initial public offerings (“IPOs”) of securities may be over-subscribed and subsequently trade at a premium in the secondary market. When BFA is given an opportunity to invest in such an initial offering or “new” or “hot” issue, the supply of securities available for client accounts is often less than the amount of securities the accounts would otherwise take. In order to allocate these investments fairly and equitably among client accounts over time, each portfolio manager or a member of his or her respective investment team will indicate to BFA’s trading desk their level of interest in a particular offering with respect to eligible clients’ accounts for which that team is responsible. IPOs of U.S. equity securities will be identified as eligible for particular client accounts that are managed by portfolio teams who have indicated interest in the offering based on market capitalization of the issuer of the security and the investment mandate of the client account and in the case of international equity securities, the country where the offering is taking place and the investment mandate of the client account. Generally, shares received during the IPO will be allocated among participating client accounts within each investment mandate on a pro rata basis. This pro rata allocation may result in a Fund receiving less of a particular security than if pro-rating had not occurred. All allocations of securities will be subject, where relevant, to share minimums established for accounts and compliance constraints. In situations where supply is too limited to be allocated among all accounts for which the investment is eligible, portfolio managers may rotate such investment opportunities among one or more accounts so long as the rotation system provides for fair access for all client accounts over time. Other allocation methodologies that are considered by BFA to be fair and equitable to clients may be used as well.

Because different accounts may have differing investment objectives and policies, BFA may buy and sell the same securities at the same time for different clients based on the particular investment objective, guidelines and strategies of those accounts. For example, BFA may decide that it may be entirely appropriate for a growth fund to sell a security at the same time a value fund is buying that security. To the extent that transactions on behalf of more than one client of BFA or the other Affiliates during the same period may increase the demand for securities being purchased or the supply of securities being sold, there may be an adverse effect on price. For example, sales of a security by BlackRock on behalf of one or more of its clients may decrease the market price of such security, adversely impacting other BlackRock clients that still hold the security. If purchases or sales of securities arise for consideration at or about the same time that would involve the Funds or other clients or funds for which BFA or another Affiliate act as investment manager, transactions in such securities will be made, insofar as feasible, for the respective funds and clients in a manner deemed equitable to all.

more favorable execution at a potentially lower execution cost. The costs associated with a bunched order will be shared pro rata among the clients in the bunched order. Generally, if an order for a particular portfolio manager or management team is filled at several different prices through multiple trades, all accounts participating in the order will receive the average price (except in the case of certain international markets where average pricing is not permitted). While in some cases this practice could have a detrimental effect upon the price or value of the security as far as the Funds are concerned, in other cases it could be beneficial to the Funds. Transactions effected by BFA or the other Affiliates on behalf of more than one of its clients during the same period may increase the demand for securities being purchased or the supply of securities being sold, causing an adverse effect on price. The trader will give the bunched order to the broker-dealer that the trader has identified as being able to provide the best execution of the order. Orders for purchase or sale of securities will be placed within a reasonable amount of time of the order receipt and bunched orders will be kept bunched only long enough to execute the order.

There were no brokerage commissions paid on behalf of each Fund for the fiscal years ended March 31, 2018, March 31, 2017 and March 31, 2016.

The Funds did not pay any brokerage commissions to BRIL, an affiliate of BFA, during the fiscal year ended March 31, 2018.

The Funds' purchase and sale orders for securities may be combined with those of other investment companies, clients or accounts that BlackRock manages or advises. If purchases or sales of portfolio securities of the Funds and one or more other accounts managed or advised by BlackRock are considered at or about the same time, transactions in such securities are allocated among the Funds and the other accounts in a manner deemed equitable to all by BlackRock. In some cases, this procedure could have a detrimental effect on the price or volume of the security as far as the Funds are concerned. However, in other cases, it is possible that the ability to participate in volume transactions and to negotiate lower transaction costs will be beneficial to the Funds. BlackRock may deal, trade and invest for its own account in the types of securities in which the Funds may invest. BlackRock may, from time to time, effect trades on behalf of and for the account of the Funds with brokers or dealers that are affiliated with BFA, in conformity with the 1940 Act and SEC rules and regulations. Under these provisions, any commissions paid to affiliated brokers or dealers must be reasonable and fair compared to the commissions charged by other brokers or dealers in comparable transactions. The Funds will not deal with affiliates in principal transactions unless permitted by applicable SEC rules or regulations, or by SEC exemptive order.

Portfolio turnover may vary from year to year, as well as within a year. High turnover rates may result in comparatively greater brokerage expenses.

The table below sets forth the portfolio turnover rates of each Fund for the fiscal years noted:

Fund	Fiscal Year ended March 31, 2018	Fiscal Year ended March 31, 2017
iShares iBonds Sep 2018 Term Muni Bond ETF	6%	0%
iShares iBonds Sep 2019 Term Muni Bond ETF	0%	0%
iShares iBonds Sep 2020 Term Muni Bond ETF	0%	0%

Additional Information Concerning the Trust

Each share has one vote with respect to matters upon which the shareholder is entitled to vote. In any matter submitted to shareholders for a vote, each fund shall hold a separate vote, provided that shareholders of all affected funds will vote together when: (i) required by the 1940 Act, or (ii) the Trustees determine that the matter affects the interests of more than one fund.

Under Delaware law, the Trust is not required to hold an annual meeting of shareholders unless required to do so under the 1940 Act. The policy of the Trust is not to hold an annual meeting of shareholders unless required to do so under the 1940 Act. All shares (regardless of the fund) have noncumulative voting rights in the election of members of the Board. Under Delaware law, Trustees of the Trust may be removed by vote of the shareholders.

Following the creation of the initial Creation Unit(s) of shares of a fund and immediately prior to the commencement of trading in such fund’s shares, a holder of shares may be a “control person” of the fund, as defined in Rule 0-1 under the 1940 Act. A fund cannot predict the length of time for which one or more shareholders may remain a control person of the fund.

Shareholders may make inquiries by writing to iShares Trust, c/o BlackRock Investments, LLC, 1 University Square Drive, Princeton, NJ 08540.

Absent an applicable exemption or other relief from the SEC or its staff, beneficial owners of more than 5% of the shares of a fund may be subject to the reporting provisions of Section 13 of the 1934 Act and the SEC’s rules promulgated thereunder. In addition, absent an applicable exemption or other relief from the SEC or its staff, officers and trustees of a fund and beneficial owners of 10% of the shares of a fund (“Insiders”) may be subject to the insider reporting, short-swing profit and short sale provisions of Section 16 of the 1934 Act and the SEC’s rules promulgated thereunder. Beneficial owners and Insiders should consult with their own legal counsel concerning their obligations under Sections 13 and 16 of the 1934 Act and existing guidance provided by the SEC staff.

In accordance with the Trust's current Agreement and Declaration of Trust (the “Declaration of Trust”), the Board may, without shareholder approval (unless such shareholder approval is required by the Declaration of Trust or applicable law, including the 1940 Act), authorize certain funds to merge, reorganize, consolidate, sell all or substantially all of their assets, or take other similar actions with, to or into another fund. The Trust or a Fund may be terminated by a majority vote of the Board, subject to the affirmative vote of a majority of the shareholders of the Trust or such Fund entitled to vote on termination; however, in certain circumstances described in the Declaration of Trust, only a majority vote of the Board is required. Although the shares are not automatically redeemable upon the occurrence of any specific event, the Declaration of Trust provides that the Board will have the unrestricted power to alter the number of shares in a Creation Unit. Therefore, in the event of a termination of the Trust or a Fund, the Board, in its sole discretion, could determine to permit the shares to be redeemable in aggregations smaller than Creation Units or to be individually redeemable. In such circumstance, the Trust or a Fund may make redemptions in-kind, for cash or for a combination of cash or securities. Further, in the event of a termination of the Trust or a Fund, the Trust or a Fund might elect to pay cash redemptions to all shareholders, with an in-kind election for shareholders owning in excess of a certain stated minimum amount.

Each Fund will wind up and terminate on or about September 1 of the relevant year. Upon a Fund's termination, it will distribute substantially all of its net assets, after making appropriate provision for any liabilities of the Fund, to then-current shareholders pursuant to a plan of liquidation. In accordance with the Declaration of Trust, each Fund will terminate on or about the date above as approved by a majority of the Board without requiring additional shareholder approval. The Board may extend the termination date if a majority of the Board determines the extension to be in the best interest of the Fund.

DTC as Securities Depository for Shares of the Funds. Shares of each Fund are represented by securities registered in the name of DTC or its nominee and deposited with, or on behalf of, DTC.

DTC was created in 1973 to enable electronic movement of securities between its participants (“DTC Participants”), and NSCC was established in 1976 to provide a single settlement system for securities clearing and to serve as central counterparty for securities trades among DTC Participants. In 1999, DTC and NSCC were consolidated within The Depository Trust & Clearing Corporation (“DTCC”) and became wholly-owned subsidiaries of DTCC. The common stock of DTCC is owned by the DTC Participants, but NYSE and FINRA, through subsidiaries, hold preferred shares in DTCC that provide them with the right to elect one member each to the DTCC board of directors. Access to the DTC system is available to entities, such as banks, brokers, dealers and trust companies, that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly (“Indirect Participants”).

Participant a written confirmation relating to their purchase of shares. The laws of some jurisdictions may require that certain purchasers of securities take physical delivery of such securities in definitive form. Such laws may impair the ability of certain investors to acquire beneficial interests in shares of the Fund.

Conveyance of all notices, statements and other communications to Beneficial Owners is effected as follows. Pursuant to the Depositary Agreement between the Trust and DTC, DTC is required to make available to the Trust upon request and for a fee to be charged to the Trust a listing of the shares of each Fund held by each DTC Participant. The Trust shall inquire of each such DTC Participant as to the number of Beneficial Owners holding shares, directly or indirectly, through such DTC Participant. The Trust shall provide each such DTC Participant with copies of such notice, statement or other communication, in such form, number and at such place as such DTC Participant may reasonably request, in order that such notice, statement or communication may be transmitted by such DTC Participant, directly or indirectly, to such Beneficial Owners. In addition, the Trust shall pay to each such DTC Participant a fair and reasonable amount as reimbursement for the expenses attendant to such transmittal, all subject to applicable statutory and regulatory requirements.

Share distributions shall be made to DTC or its nominee, Cede & Co., as the registered holder of all shares of the Trust. DTC or its nominee, upon receipt of any such distributions, shall credit immediately DTC Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in shares of each Fund as shown on the records of DTC or its nominee. Payments by DTC Participants to Indirect Participants and Beneficial Owners of shares held through such DTC Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a “street name,” and will be the responsibility of such DTC Participants.

Distribution of Shares. In connection with each Fund's launch, each Fund was seeded through the sale of one or more Creation Units by each Fund to one or more initial investors. Initial investors participating in the seeding may be Authorized Participants, a lead market maker or other third party investor or an affiliate of each Fund or each Fund’s adviser. Each such initial investor may sell some or all of the shares underlying the Creation Unit(s) held by them pursuant to the registration statement for each Fund (each, a “Selling Shareholder”), which shares have been registered to permit the resale from time to time after purchase. Each Fund will not receive any of the proceeds from the resale by the Selling Shareholders of these shares.

Any Selling Shareholder and any other person participating in such distribution will be subject to applicable provisions of the 1934 Act and the rules and regulations thereunder.

Creation and Redemption of Creation Units

General. The Trust issues and sells shares of each Fund only in Creation Units on a continuous basis through the Distributor or its agent, without a sales load, at a price based on the NAV next determined after receipt, on any Business Day (as defined below), of an order received by the Distributor or its agent in proper form. On days when the Listing Exchange or the bond markets close earlier than normal, the Funds may require orders to be placed earlier in the day. The following table sets forth the number of shares of a Fund that constitute a Creation Unit for such Fund and the approximate value of such Creation Unit as of April 30, 2018:

Fund	Shares Per Creation Unit	Approximate Value Per Creation Unit (U.S.$)
iShares iBonds Sep 2018 Term Muni Bond ETF	50,000	$1,270,000
iShares iBonds Sep 2019 Term Muni Bond ETF	50,000	1,264,500
iShares iBonds Sep 2020 Term Muni Bond ETF	50,000	1,261,000

In its discretion, the Trust reserves the right to increase or decrease the number of a Fund’s shares that constitute a Creation Unit. The Board reserves the right to declare a split or a consolidation in the number of shares outstanding of any Fund, and to make a corresponding change in the number of shares constituting a Creation Unit, in the event that the per share price in the secondary market rises (or declines) to an amount that falls outside the range deemed desirable by the Board.

A “Business Day” with respect to each Fund is any day on which the Listing Exchange on which the Fund is listed for trading is open for business. As of the date of this SAI, each Listing Exchange observes the following holidays, as observed: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

Fund Deposit. The consideration for purchase of Creation Units of each Fund generally consists of the in-kind deposit of a designated portfolio of securities (including any portion of such securities for which cash may be substituted) (Deposit Securities) and the Cash Component computed as described below. Together, the Deposit Securities and the Cash Component constitute the “Fund Deposit,” which, when combined with the Fund's portfolio securities, is designed to generate performance that has a collective investment profile similar to that of the Underlying Index. The Fund Deposit represents the minimum initial and subsequent investment amount for a Creation Unit of any Fund.

To facilitate efficient management of each Fund and to enable each Fund to track its Underlying Index, the Deposit Securities required for purchase of a Creation Unit may not be identical to the Fund Securities (as defined below under “Redemption of Creation Units”) a Fund will deliver upon redemption of Fund shares. The Deposit Securities and Fund Securities, as applicable, in connection with a purchase or redemption of a Creation Unit, generally will correspond pro rata, to the extent practicable, to the securities held by a Fund. As the planned termination date of the Fund approaches, and particularly as the bonds held by the Fund begin to mature, the Fund expects to effect both creations and redemptions increasingly for cash. Consistent with the exemptive orders granted to the Funds by the SEC, Creation Baskets will correspond generally to the price and yield performance of each Fund's Underlying Index.

BFA makes available through the NSCC on each Business Day prior to the opening of business on the Listing Exchange, the list of names and the required number or par value of each Deposit Security and the amount of the Cash Component to be included in the current Fund Deposit (based on information as of the end of the previous Business Day for each Fund). Such Fund Deposit is applicable, subject to any adjustments as described below, to purchases of Creation Units of shares of a given Fund until such time as the next-announced Fund Deposit is made available.

The identity and number or par value of the Deposit Securities change pursuant to changes in the composition of a Fund's portfolio and as rebalancing adjustments and corporate action events are reflected from time to time by BFA with a view to the investment objective of the Fund. The composition of the Deposit Securities may also change in response to adjustments to the weighting or composition of the component securities constituting the relevant Underlying Index.

The Funds reserve the right to permit or require the substitution of a “cash in lieu” amount to be added to the Cash Component to replace any Deposit Security that may not be available in sufficient quantity for delivery or that may not be eligible for transfer through DTC or the clearing process (as discussed below) or that the Authorized Participant is not able to trade due to a trading restriction. The Funds also reserve the right to permit or require a “cash in lieu” amount in certain circumstances, including circumstances in which the delivery of the Deposit Security by the Authorized Participant would be restricted under applicable securities or other local laws or in certain other situations.

Cash Purchase Method. Although the Trust does not generally permit partial or full cash purchases of Creation Units of its funds, when partial or full cash purchases of Creation Units are available or specified for a Fund, they will be effected in essentially the same manner as in-kind purchases thereof. In the case of a partial or full cash purchase, the Authorized Participant must pay the cash equivalent of the Deposit Securities it would otherwise be required to provide through an in-kind purchase, plus the same Cash Component required to be paid by an in-kind purchaser.

Procedures for Creation of Creation Units. To be eligible to place orders with the Distributor and to create a Creation Unit of the Funds, an entity must be: (i) a “Participating Party,” i.e., a broker-dealer or other participant in the clearing process through the Continuous Net Settlement System of the NSCC (the “Clearing Process”), a clearing agency that is registered with the SEC, or (ii) a DTC Participant, and must have executed an agreement with the Distributor, with respect to creations and redemptions of Creation Units (“Authorized Participant Agreement”) (discussed below). A Participating Party or DTC Participant who has executed an Authorized Participant Agreement is referred to as an “Authorized Participant.” All shares of the Funds, however created, will be entered on the records of DTC in the name of Cede & Co. for the account of a DTC Participant.

Role of the Authorized Participant. Creation Units may be purchased only by or through a DTC Participant that has entered into an Authorized Participant Agreement with the Distributor. Such Authorized Participant will agree, pursuant to the terms of such Authorized Participant Agreement and on behalf of itself or any investor on whose behalf it will act, to certain conditions, including that such Authorized Participant will make available in advance of each purchase of shares an amount of cash sufficient to pay the Cash Component, once the net asset value of a Creation Unit is next determined after receipt of the purchase order in proper form, together with the transaction fees described below. An Authorized Participant, acting on behalf of an investor, may require the investor to enter into an agreement with such Authorized Participant with respect to certain matters, including payment of the Cash Component. Investors who are not Authorized Participants must make appropriate arrangements with an Authorized Participant. Investors should be aware that their particular broker may not be a DTC Participant or may not have executed an Authorized Participant Agreement and that orders to purchase Creation Units may have to be placed by the investor's broker through an Authorized Participant. As a result, purchase orders placed through an Authorized Participant may result in additional charges to such investor. The Trust does not expect to enter into an Authorized Participant Agreement with more than a small number of DTC Participants. A list of current Authorized Participants may be obtained from the Distributor. The Distributor has adopted guidelines regarding Authorized Participants’ transactions in Creation Units that are made available to all Authorized Participants. These guidelines set forth the processes and standards for Authorized Participants to transact with the Distributor and its agents in connection with creation and redemption transactions. In addition, the Distributor may be appointed as the proxy of the Authorized Participant and may be granted a power of attorney under its Authorized Participant Agreement.

Placement of Creation Orders. Fund Deposits must be delivered through the Federal Reserve System (for cash and U.S. government securities), through DTC (for corporate and municipal securities) or through a central depository account, such as with Euroclear or DTC, maintained by State Street or a sub-custodian (a “Central Depository Account”). Any portion of a Fund Deposit that may not be delivered through the Federal Reserve System or DTC must be delivered through a Central Depository Account. The Fund Deposit transfers made through DTC must be ordered by the DTC Participant in a timely fashion so as to ensure the delivery of the requisite number of Deposit Securities through DTC to the account of the Funds generally before 3:00 p.m., Eastern time on the Settlement Date. Fund Deposit transfers made through the Federal Reserve System must be deposited by the participant institution in a timely fashion so as to ensure the delivery of the requisite number or amount of Deposit Securities or cash through the Federal Reserve System to the account of the Fund generally before 3:00 p.m., Eastern time on the Settlement Date. Fund Deposit transfers made through a Central Depository Account

must be completed pursuant to the requirements established by the Custodian or sub-custodian for such Central Depository Account generally before 2:00 p.m., Eastern time on the Settlement Date. The “Settlement Date” for all funds is generally the second business day after the Transmittal Date. All questions as to the number of Deposit Securities to be delivered, and the validity, form and eligibility (including time of receipt) for the deposit of any tendered securities, will be determined by the Trust, whose determination shall be final and binding. The amount of cash equal to the Cash Component must be transferred directly to State Street through the Federal Reserve Bank wire transfer system in a timely manner so as to be received by State Street generally before 3:00 p.m., Eastern time on the Settlement Date. If the Cash Component and the Deposit Securities are not received by 3:00 p.m., Eastern time on the Settlement Date, the creation order may be canceled. Upon written notice to the Distributor, such canceled order may be resubmitted the following Business Day using a Fund Deposit as newly constituted to reflect the then current NAV of the Funds. The delivery of Creation Units so created generally will occur no later than the second Business Day following the day on which the purchase order is deemed received by the Distributor, provided that the relevant Fund Deposit has been received by the Funds prior to such time.

Purchase Orders. To initiate an order for a Creation Unit, an Authorized Participant must submit to the Distributor or its agent an irrevocable order to purchase shares of a Fund, in proper form, generally before 4:00 p.m., Eastern time on any Business Day to receive that day’s NAV. The Distributor or its agent will notify BFA and the custodian of such order. The custodian will then provide such information to any appropriate sub-custodian. Procedures and requirements governing the delivery of the Fund Deposit are set forth in the procedures handbook for Authorized Participants and may change from time to time. Investors, other than Authorized Participants, are responsible for making arrangements for a creation request to be made through an Authorized Participant. The Distributor or its agent will provide a list of current Authorized Participants upon request. Those placing orders to purchase Creation Units through an Authorized Participant should allow sufficient time to permit proper submission of the purchase order to the Distributor or its agent by the Cutoff Time (as defined below) on such Business Day.

The Authorized Participant must also make available on or before the contractual settlement date, by means satisfactory to the Funds, immediately available or same day funds estimated by the Funds to be sufficient to pay the Cash Component next determined after acceptance of the purchase order, together with the applicable purchase transaction fees. Those placing orders should ascertain the applicable deadline for cash transfers by contacting the operations department of the broker or depositary institution effectuating the transfer of the Cash Component. This deadline is likely to be significantly earlier than the Cutoff Time of the Funds. Investors should be aware that an Authorized Participant may require orders for purchases of shares placed with it to be in the particular form required by the individual Authorized Participant.

The Authorized Participant is responsible for any and all expenses and costs incurred by a Fund, including any applicable cash amounts, in connection with any purchase order.

Timing of Submission of Purchase Orders. An Authorized Participant must submit an irrevocable order to purchase shares of a Fund generally before 4:00 p.m., Eastern time on any Business Day in order to receive that day's NAV. Creation Orders must be transmitted by an Authorized Participant in the form required by the Funds to the Distributor or its agent pursuant to procedures set forth in the Authorized Participant Agreement. Economic or market disruptions or changes, or telephone or other communication failure, may impede the ability to reach the Distributor or its agent or an Authorized Participant. Each Fund's deadline specified above for the submission of purchase orders is referred to as that Fund's “Cutoff Time.” The Distributor or its agent, in their discretion, may permit the submission of such orders and requests by or through an Authorized Participant at any time (including on days on which the Listing Exchange is not open for business) via communication through the facilities of the Distributor's or its agent's proprietary website maintained for this purpose. Purchase orders and redemption requests, if accepted by the Trust, will be processed based on the NAV next determined after such acceptance in accordance with a Fund's Cutoff Times as provided in the Authorized Participant Agreement and disclosed in this SAI.

Acceptance of Orders for Creation Units. Subject to the conditions that (i) an irrevocable purchase order has been submitted by the Authorized Participant (either on its own or another investor's behalf) and (ii) arrangements satisfactory to the Funds are in place for payment of the Cash Component and any other cash amounts which may be due, the Funds will accept the order, subject to each Fund's right (and the right of the Distributor and BFA) to reject any order until acceptance, as set forth below.

Once a Fund has accepted an order, upon the next determination of the net asset value of the shares, the Fund will confirm the issuance of a Creation Unit, against receipt of payment, at such net asset value. The Distributor or its agent will then transmit a confirmation of acceptance to the Authorized Participant that placed the order.

Each Fund reserves the absolute right to reject or revoke a creation order transmitted to it by the Distributor or its agent if (i) the order is not in proper form; (ii) the investor(s), upon obtaining the shares ordered, would own 80% or more of the currently outstanding shares of the Fund; (iii) the Deposit Securities delivered do not conform to the identity and number of shares specified, as described above; (iv) acceptance of the Deposit Securities would have certain adverse tax consequences to the Fund; (v) acceptance of the Fund Deposit would, in the opinion of counsel, be unlawful; (vi) acceptance of the Fund Deposit would, in the discretion of the Fund or BFA, have an adverse effect on the Fund or the rights of beneficial owners; or (vii) circumstances outside the control of the Fund, the Distributor or its agent and BFA make it impracticable to process purchase orders. The Distributor or its agent shall notify a prospective purchaser of a Creation Unit and/or the Authorized Participant acting on behalf of such purchaser of its rejection of such order. The Funds, State Street, the sub-custodian and the Distributor or its agent are under no duty, however, to give notification of any defects or irregularities in the delivery of Fund Deposits nor shall any of them incur any liability for failure to give such notification.

To the extent contemplated by an Authorized Participant Agreement with the Distributor, each Fund will issue Creation Units to such Authorized Participant, notwithstanding the fact that the corresponding Fund Deposits have not been received in part or in whole, in reliance on the undertaking of the Authorized Participant to deliver the missing Deposit Securities as soon as possible, which undertaking shall be secured by such Authorized Participant's delivery and maintenance of collateral having a value at least equal to 105% and up to 115%, which percentage BFA may change at any time, in its sole discretion, of the value of the missing Deposit Securities in accordance with the Funds' then-effective procedures. The Trust may use such cash deposit at any time to buy Deposit Securities for the Funds. The only collateral that is acceptable to the Funds is cash in U.S. dollars. Such cash collateral must be delivered no later than the time specified by a Fund or its custodian on the contractual settlement date. The cash collateral posted by the Authorized Participant may be invested at the risk of the Authorized Participant, and income, if any, on invested cash collateral will be paid to that Authorized Participant. Information concerning the Funds' current procedures for collateralization of missing Deposit Securities is available from the Distributor or its agent. The Authorized Participant Agreement will permit the Funds to buy the missing Deposit Securities at any time and will subject the Authorized Participant to liability for any shortfall between the cost to the Funds of purchasing such securities and the cash collateral including, without limitation, liability for related brokerage, borrowings and other charges.

In certain cases, Authorized Participants may create and redeem Creation Units on the same trade date and in these instances, the Funds reserve the right to settle these transactions on a net basis or require a representation from the Authorized Participants that the creation and redemption transactions are for separate beneficial owners. All questions as to the number of shares of each security in the Deposit Securities and the validity, form, eligibility and acceptance for deposit of any securities to be delivered shall be determined by each Fund and the Fund's determination shall be final and binding.

Costs Associated with Creation Transactions. A standard creation transaction fee is imposed to offset the transfer and other transaction costs associated with the issuance of Creation Units. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same, regardless of the number of Creation Units purchased by the Authorized Participant on the applicable Business Day. If a purchase consists solely or partially of cash, the Authorized Participant may also be required to cover (up to the maximum amount shown below) certain brokerage, tax, foreign exchange, execution, price movement and other costs and expenses related to the execution of trades resulting from such transaction (which may, in certain instances, be based on a good faith estimate of transaction costs). Authorized Participants will also bear the costs of transferring the Deposit Securities to the Funds. Certain fees/costs associated with creation transactions may be waived in certain circumstances. Investors who use the services of a broker or other financial intermediary to acquire Fund shares may be charged a fee for such services.

The following table sets forth each Fund's standard creation transaction fees and maximum additional charge (as described above):

Fund	Standard Creation Transaction Fee	Maximum Additional Charge for Creations*
iShares iBonds Sep 2018 Term Muni Bond ETF	$ 125	3.0%
iShares iBonds Sep 2019 Term Muni Bond ETF	150	3.0%
iShares iBonds Sep 2020 Term Muni Bond ETF	150	3.0%

*	As a percentage of the net asset value per Creation Unit.

Redemption of Creation Units. Shares of a Fund may be redeemed by Authorized Participants only in Creation Units at their NAV next determined after receipt of a redemption request in proper form by the Distributor or its agent and only on a Business Day. The Funds will not redeem shares in amounts less than Creation Units. There can be no assurance, however, that there will be sufficient liquidity in the secondary market at any time to permit assembly of a Creation Unit. Investors should expect to incur brokerage and other costs in connection with assembling a sufficient number of shares to constitute a Creation Unit that could be redeemed by an Authorized Participant. Beneficial owners also may sell shares in the secondary market.

Each Fund generally redeems Creation Units for Fund Securities (as defined below). Please see the Cash Redemption Method section below and the following discussion summarizing the in-kind method for further information on redeeming Creation Units of the Funds.

BFA makes available through the NSCC, prior to the opening of business on the Listing Exchange on each Business Day, the designated portfolio of securities (including any portion of such securities for which cash may be substituted) that will be applicable (subject to possible amendment or correction) to redemption requests received in proper form (as defined below) on that day (“Fund Securities”), and an amount of cash (the “Cash Amount,” as described below). Such Fund Securities and the corresponding Cash Amount (each subject to possible amendment or correction) are applicable, in order to effect redemptions of Creation Units of a Fund until such time as the next announced composition of the Fund Securities and Cash Amount is made available. Fund Securities received on redemption may not be identical to Deposit Securities that are applicable to creations of Creation Units. Procedures and requirements governing redemption transactions are set forth in the handbook for Authorized Participants and may change from time to time.

Unless cash redemptions are available or specified for a Fund, the redemption proceeds for a Creation Unit generally consist of Fund Securities, plus the Cash Amount, which is an amount equal to the difference between the net asset value of the shares being redeemed, as next determined after the receipt of a redemption request in proper form, and the value of Fund Securities, less a redemption transaction fee (as described below).

The Trust may, in its sole discretion, substitute a “cash in lieu” amount to replace any Fund Security. The Trust also reserves the right to permit or require a “cash in lieu” amount in certain circumstances, including circumstances in which: (i) the delivery of a Fund Security to the Authorized Participant would be restricted under applicable securities or other local laws; or (ii) the delivery of a Fund Security to the Authorized Participant would result in the disposition of the Fund Security by the Authorized Participant due to restrictions under applicable securities or other local laws, or in certain other situations. The amount of cash paid out in such cases will be equivalent to the value of the substituted security listed as a Fund Security. In the event that the Fund Securities have a value greater than the NAV of the shares, a compensating cash payment equal to the difference is required to be made by or through an Authorized Participant by the redeeming shareholder. Each Fund generally redeems Creation Units for Fund Securities, but the Fund reserves the right to utilize a cash option for redemption of Creation Units. Each Fund may, in its sole discretion, provide such redeeming Authorized Participant a portfolio of securities that differs from the exact composition of the Fund Securities, but does not differ in NAV.

Cash Redemption Method. Although the Trust does not generally permit partial or full cash redemptions of Creation Units of its funds, when partial or full cash redemptions of Creation Units are available or specified for a Fund, they will be effected in essentially the same manner as in-kind redemptions thereof. In the case of partial or full cash redemption, the Authorized Participant receives the cash equivalent of the Fund Securities it would otherwise receive through an in-kind redemption, plus the same Cash Amount to be paid to an in-kind redeemer.

Costs Associated with Redemption Transactions. A standard redemption transaction fee is imposed to offset transfer and other transaction costs that may be incurred by the relevant Fund. The standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by an Authorized Participant on the applicable Business Day. If a redemption consists solely or partially of cash, the Authorized Participant may also be required to cover (up to the maximum amount shown below) certain brokerage, tax, foreign exchange, execution, price movement and other costs and expenses related to the execution of trades resulting from such transaction (which may, in certain instances, be based on a good faith estimate of transaction costs). Authorized Participants will also bear the costs of transferring the Fund Securities from a Fund to their account on their order. Certain fees/costs associated with redemption transactions may be waived in certain circumstances. Investors who use the services of a broker or other financial intermediary to dispose of Fund shares may be charged a fee for such services.

The following table sets forth each Fund's standard redemption transaction fees and maximum additional charge (as described above):

Fund	Standard Redemption Transaction Fee	Maximum Additional Charge for Redemptions*
iShares iBonds Sep 2018 Term Muni Bond ETF	$ 125	2.0%
iShares iBonds Sep 2019 Term Muni Bond ETF	150	2.0%
iShares iBonds Sep 2020 Term Muni Bond ETF	150	2.0%

*	As a percentage of the net asset value per Creation Unit, inclusive of the standard redemption transaction fee.

Placement of Redemption Orders. Redemption requests for Creation Units of the Funds must be submitted to the Distributor or its agent by or through an Authorized Participant. An Authorized Participant must submit an irrevocable request to redeem shares of a Fund generally before 4:00 p.m., Eastern time on any Business Day in order to receive that day's NAV. On days when the Listing Exchange closes earlier than normal, a Fund may require orders to redeem Creation Units to be placed earlier that day. Investors, other than Authorized Participants, are responsible for making arrangements for a redemption request to be made through an Authorized Participant. The Distributor or its agent will provide a list of current Authorized Participants upon request.

The Authorized Participant must transmit the request for redemption in the form required by the Funds to the Distributor or its agent in accordance with procedures set forth in the Authorized Participant Agreement. Investors should be aware that their particular broker may not have executed an Authorized Participant Agreement and that, therefore, requests to redeem Creation Units may have to be placed by the investor's broker through an Authorized Participant who has executed an Authorized Participant Agreement. At any time, only a limited number of broker-dealers will have an Authorized Participant Agreement in effect. Investors making a redemption request should be aware that such request must be in the form specified by such Authorized Participant. Investors making a request to redeem Creation Units should allow sufficient time to permit proper submission of the request by an Authorized Participant and transfer of the shares to the Funds' transfer agent; such investors should allow for the additional time that may be required to effect redemptions through their banks, brokers or other financial intermediaries if such intermediaries are not Authorized Participants.

A redemption request is considered to be in “proper form” if: (i) an Authorized Participant has transferred or caused to be transferred to the Funds' transfer agent the Creation Unit redeemed through the book-entry system of DTC so as to be effective by the Listing Exchange closing time on any Business Day on which the redemption request is submitted; (ii) a request in form satisfactory to the applicable Fund is received by the Distributor or its agent from the Authorized Participant on behalf of itself or another redeeming investor within the time periods specified above; and (iii) all other procedures set forth in the Authorized Participant Agreement are properly followed.

Upon receiving a redemption request, the Distributor or its agent shall notify the applicable Fund and the Fund's transfer agent of such redemption request. The tender of an investor's shares for redemption and the distribution of the securities and/or cash included in the redemption payment made in respect of Creation Units redeemed will be made through DTC and the relevant Authorized Participant to the Beneficial Owner thereof as recorded on the book-entry system of DTC or the DTC Participant through which such investor holds, as the case may be, or by such other means specified by the Authorized Participant submitting the redemption request.

Deliveries of redemption proceeds by each Fund are generally made within two Business Days (i.e., “T+2”). Each Fund reserves the right to settle redemption transactions on a basis other than T+2 but by T+7, if necessary or appropriate under the circumstances and compliant with applicable law. Delayed settlement may occur due to a number of different reasons, including, without limitation, settlement cycles for the underlying securities, unscheduled market closings, an effort to link distribution to dividend record dates and ex-dates and newly announced holidays. For example, the redemption settlement process may be extended beyond T+2 because of the occurrence of a holiday in a non-U.S. market or in the U.S. bond market that is not a holiday observed in the U.S. equity market.

To the extent contemplated by an Authorized Participant's agreement with the Distributor or its agent, in the event an Authorized Participant has submitted a redemption request in proper form but is unable to transfer all or part of the Creation Unit to be redeemed to the Fund, at or prior to 10:00 a.m., Eastern time on the Listing Exchange business day after the date of submission of such redemption request, the Distributor or its agent will accept the redemption request in reliance on the undertaking by the Authorized Participant to deliver the missing shares as soon as possible. Such undertaking shall be secured by the Authorized Participant's delivery and maintenance of collateral consisting of cash, in U.S. dollars in immediately available funds, having a value at least equal to 105% and up to 115%, which percentage BFA may change at any time, in its sole discretion, of the value of the missing shares. Such cash collateral must be delivered no later than the time specified by a Fund or its custodian on the day after the date of submission of such redemption request and shall be held by State Street and marked-to-market daily. The fees of State Street and any sub-custodians in respect of the delivery, maintenance and redelivery of the cash collateral shall be payable by the Authorized Participant. The cash collateral posted by the Authorized Participant may be invested at the risk of the Authorized Participant, and income, if any, on invested cash collateral will be paid to that Authorized Participant. The Authorized Participant Agreement permits the Funds to acquire shares of the Funds at any time and subjects the Authorized Participant to liability for any shortfall between the aggregate of the cost to the Funds of purchasing such shares, plus the value of the Cash Amount, and the value of the cash collateral together with liability for related brokerage and other charges.

The right of redemption may be suspended or the date of payment postponed with respect to any Fund: (i) for any period during which the Listing Exchange is closed (other than customary weekend and holiday closings); (ii) for any period during which trading on the Listing Exchange is suspended or restricted; (iii) for any period during which an emergency exists as a result of which disposal of the shares of the Fund's portfolio securities or determination of its net asset value is not reasonably practicable; or (iv) in such other circumstance as is permitted by the SEC.

Taxes

The following is a summary of certain material U.S. federal income tax considerations regarding the purchase, ownership and disposition of shares of a Fund. This summary does not address all of the potential U.S. federal income tax consequences that may be applicable to a Fund or to all categories of investors, some of which may be subject to special tax rules. Current and prospective shareholders are urged to consult their own tax advisors with respect to the specific federal, state, local and non-U.S. tax consequences of investing in a Fund. The summary is based on the laws and judicial and administrative interpretations thereof in effect on the date of this SAI, all of which are subject to change, possibly with retroactive effect.

Tax reform legislation commonly known as the Tax Cuts and Jobs Act (the “Tax Act”) was enacted on December 22, 2017. The Tax Act makes significant changes to the U.S. federal income tax rules for individuals and corporations, generally effective for taxable years beginning after December 31, 2017. Most of the changes applicable to individuals are temporary and, without further legislation, will not apply after 2025. The application of certain provisions of the Tax Act is uncertain, and the changes in the act may have indirect effects on a Fund, its investments and its shareholders that cannot be predicted. In addition, legislative, regulatory or administrative changes could be enacted or promulgated at any time, either prospectively or with retroactive effect. Prospective investors should consult their tax advisors regarding the implications of the Tax Act on their investment in a Fund.

Regulated Investment Company Qualifications. Each Fund intends to continue to qualify for and to elect treatment as a separate RIC under Subchapter M of the Internal Revenue Code. To qualify for treatment as a RIC, each Fund must annually distribute at least 90% of its investment company taxable income (which includes dividends, interest and net short-term capital gains) and meet several other requirements. Among such other requirements are the following: (i) at least 90% of each Fund’s annual gross income must be derived from dividends, interest, payments with respect to securities loans, gains from the sale or other disposition of stock or securities or non-U.S. currencies, other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies, and net income derived from interests in qualified publicly-traded partnerships (i.e., partnerships that are traded on an established securities market or tradable on a secondary market, other than a partnership that derives at least 90% of its income from interest, dividends, capital gains and other traditionally permitted RIC income); and (ii) at the close of each quarter of each Fund’s taxable year, (a) at least 50% of the market value of each Fund’s total assets must be represented by cash and cash items, U.S. government securities, securities of other RICs and other securities, with such other securities limited for purposes of this calculation in respect of any one issuer to an amount not greater than 5% of the value of the Fund’s assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of the Fund’s total assets may be invested in the securities of any one issuer, of two or more issuers of which 20% or more of the voting stock is held by the Fund and that are engaged in the same or similar trades or businesses or related trades or businesses (other than the securities of other RICs) or the securities of one or more qualified publicly-traded partnerships.

A Fund may be able to cure a failure to derive at least 90% of its income from the sources specified above or a failure to diversify its holdings in the manner described above by paying a tax and/or by disposing of certain assets. If, in any taxable year, a Fund fails one of these tests and does not timely cure the failure, that Fund will be taxed in the same manner as an ordinary corporation and distributions to its shareholders will not be deductible by that Fund in computing its taxable income.

Although in general the passive loss rules of the Internal Revenue Code do not apply to RICs, such rules do apply to a RIC with respect to items attributable to an interest in a qualified publicly-traded partnership. A Fund’s investments in partnerships, including in qualified publicly-traded partnerships, may result in the Fund being subject to state, local, or non-U.S. income, franchise or withholding tax liabilities.

Fund will be subject to income tax at regular corporate rates on any taxable income or gains that it does not distribute to its shareholders. If a Fund fails to qualify for any taxable year as a RIC or fails to meet the distribution requirement, all of its taxable income will be subject to tax at regular corporate income tax rates without any deduction for distributions to shareholders, and such distributions generally will be taxable to shareholders as ordinary dividends to the extent of the Fund’s current and accumulated earnings and profits. In such event, distributions to individuals should be eligible to be treated as qualified dividend income and distributions to corporate shareholders generally should be eligible for the dividends-received deduction. Although each Fund intends to distribute substantially all of its net investment income and its capital gains for each taxable year, each Fund will be subject to U.S. federal income taxation to the extent any such income or gains are not distributed. Moreover, if a Fund fails to qualify as a RIC in any year, it must pay out its earnings and profits accumulated in that year in order to qualify again as a RIC. If a Fund fails to qualify as a RIC for a period greater than two taxable years, the Fund may be required to recognize any net built-in gains with respect to certain of its assets (i.e., the excess of the aggregate gains, including items of income, over aggregate losses that would have been realized with respect to such assets if the Fund had been liquidated) if it qualifies as a RIC in a subsequent year.

Net Capital Loss Carryforwards. Net capital loss carryforwards may be applied against any net realized capital gains in each succeeding year, until they have been reduced to zero.

In the event that a Fund were to experience an ownership change as defined under the Internal Revenue Code, the loss carryforwards and other favorable tax attributes of a Fund, if any, may be subject to limitation.

The following Funds had net capital loss carryforwards, as set forth in the table below, as of March 31, 2018, the tax year-end for the Funds:

Fund		Non-Expiring
iShares iBonds Sep 2018 Term Muni Bond ETF		$77,687
iShares iBonds Sep 2019 Term Muni Bond ETF		1,385
iShares iBonds Sep 2020 Term Muni Bond ETF		3,981

Excise Tax. A Fund will be subject to a 4% excise tax on certain undistributed income if it does not distribute to its shareholders in each calendar year at least 98% of its ordinary income for the calendar year plus at least 98.2% of its capital gain net income for the 12 months ended October 31 of such year. For this purpose, however, any ordinary income or capital gain net income retained by a Fund that is subject to corporate income tax will be considered to have been distributed by year-end. In addition, the minimum amounts that must be distributed in any year to avoid the excise tax will be increased or decreased to reflect any underdistribution or overdistribution, as the case may be, from the previous year. Each Fund intends to declare and distribute dividends and distributions in the amounts and at the times necessary to avoid the application of this 4% excise tax.

Taxation of U.S. Shareholders. Dividends and other distributions by a Fund are generally treated under the Internal Revenue Code as received by the shareholders at the time the dividend or distribution is made. However, any dividend or capital gain distribution declared by a Fund in October, November or December of any calendar year and payable to shareholders of record on a specified date in such a month shall be deemed to have been received by each shareholder on December 31 of such calendar year and to have been paid by the Fund not later than such December 31, provided such dividend is actually paid by the Fund during January of the following calendar year.

Each Fund intends to distribute annually to its shareholders substantially all of its net tax-exempt income, investment company taxable income and any net realized long-term capital gains in excess of net realized short-term capital losses (including any capital loss carryovers). However, if a Fund retains for investment an amount equal to all or a portion of its net long-term capital gains in excess of its net short-term capital losses (including any capital loss carryovers), it will be subject to a corporate tax (at a flat rate of 21%) on the amount retained. In that event, the Fund will report such retained amounts as undistributed capital gains in a notice to its shareholders who (a) will be required to include in income for U.S. federal income tax purposes, as long-term capital gains, their proportionate shares of the undistributed amount, (b) will be entitled to credit their proportionate shares of the tax paid by the Fund on the undistributed amount against their U.S. federal income tax liabilities, if any, and to claim refunds to the extent their credits exceed their liabilities, if any, and (c) will be entitled to

increase their tax basis, for U.S. federal income tax purposes, in their shares by an amount equal to the excess of the amount in clause (a) over the amount in clause (b). Organizations or persons not subject to U.S. federal income tax on such capital gains will be entitled to a refund of their pro rata share of such taxes paid by the Fund upon filing appropriate returns or claims for refund with the IRS.

Distributions of net realized long-term capital gains, if any, that a Fund reports as capital gain dividends are taxable as long-term capital gains, whether paid in cash or in shares and regardless of how long a shareholder has held shares of the Fund. All other dividends of a Fund (including dividends from short-term capital gains) from its current and accumulated earnings and profits (“regular dividends”) are generally subject to tax as ordinary income. Long-term capital gains are eligible for taxation at a maximum rate of 15% or 20% for non-corporate shareholders, depending on whether their income exceeds certain threshold amounts.

If an individual receives a regular dividend qualifying for the long-term capital gain rates and such dividend constitutes an “extraordinary dividend,” and the individual subsequently recognizes a loss on the sale or exchange of stock in respect of which the extraordinary dividend was paid, then the loss will be long-term capital loss to the extent of such extraordinary dividend. An “extraordinary dividend” on common stock for this purpose is generally a dividend (i) in an amount greater than or equal to 10% of the taxpayer’s tax basis (or trading value) in a share of stock, aggregating dividends with ex-dividend dates within an 85-day period, or (ii) in an amount greater than 20% of the taxpayer’s tax basis (or trading value) in a share of stock, aggregating dividends with ex-dividend dates within a 365-day period.

Distributions in excess of a Fund’s current and accumulated earnings and profits will, as to each shareholder, be treated as a tax-free return of capital to the extent of a shareholder’s basis in shares of the Fund, and as a capital gain thereafter (if the shareholder holds shares of the Fund as capital assets). Distributions in excess of a Fund’s minimum distribution requirements, but not in excess of the Fund’s earnings and profits, will be taxable to shareholders and will not constitute nontaxable returns of capital. The Fund's capital loss carryovers, if any, carried from taxable years beginning before 2011 do not reduce current earnings and profits, even if such carryforwards offset current year realized gains. Shareholders receiving dividends or distributions in the form of additional shares should be treated for U.S. federal income tax purposes as receiving a distribution in an amount equal to the amount of money that the shareholders receiving cash dividends or distributions will receive and should have a cost basis in the shares received equal to such amount. No deduction would be allowed to an investor for interest on indebtedness incurred or continued to purchase or carry shares of the Fund to the extent the interest deduction would relate to exempt-interest dividends received.

Investors considering buying shares just prior to a dividend or capital gain distribution should be aware that, although the price of shares purchased at that time may reflect the amount of the forthcoming distribution, such dividend or distribution may nevertheless be taxable to them. If a Fund is the holder of record of any security on the record date for any dividends payable with respect to such security, such dividends will be included in the Fund’s gross income not as of the date received but as of the later of (i) the date such security became ex-dividend with respect to such dividends (i.e., the date on which a buyer of the security would not be entitled to receive the declared, but unpaid, dividends); or (ii) the date the Fund acquired such security. Accordingly, in order to satisfy its income distribution requirements, a Fund may be required to pay dividends based on anticipated earnings, and shareholders may receive dividends in an earlier year than would otherwise be the case.

In certain situations, a Fund may, for a taxable year, defer all or a portion of its net capital loss (or if there is no net capital loss, then any net long-term or short-term capital loss) realized after October and its late-year ordinary loss (defined as the sum of the excess of post-October foreign currency and passive foreign investment company (“PFIC”) losses over post-October foreign currency and PFIC gains, plus the excess of post-December ordinary losses over post-December ordinary income) until the next taxable year in computing its investment company taxable income and net capital gain, which will defer the recognition of such realized losses. Such deferrals and other rules regarding gains and losses realized after October (or December) may affect the tax character of shareholder distributions.

in the shareholder’s hands and will be long-term capital gain or loss if the shares are held for more than one year and short-term capital gain or loss if the shares are held for one year or less. Any loss realized on a sale or exchange will be disallowed to the extent the shares disposed of are replaced, including replacement through the reinvesting of dividends or capital gains distributions, or by an option, or contract to acquire substantially identical shares, within a 61-day period beginning 30 days before and ending 30 days after the disposition of the shares. In such a case, the basis of the shares acquired will be increased to reflect the disallowed loss. Any loss realized by a shareholder on the sale of Fund shares held by the shareholder for six months or less will be treated for U.S. federal income tax purposes as a long-term capital loss to the extent of any distributions or deemed distributions of long-term capital gains received by the shareholder with respect to such share. The Medicare contribution tax described above will apply to the sale of Fund shares.

If a shareholder incurs a sales charge in acquiring shares of a Fund, disposes of those shares within 90 days and then, on or before January 31 of the following calendar year, acquires shares in a mutual fund for which the otherwise applicable sales charge is reduced by reason of a reinvestment right (e.g., an exchange privilege), the original sales charge will not be taken into account in computing gain/loss on the original shares to the extent the subsequent sales charge is reduced. Instead, the disregarded portion of the original sales charge will be added to the tax basis of the newly acquired shares. Furthermore, the same rule also applies to a disposition of the newly acquired shares made within 90 days of the second acquisition. This provision prevents a shareholder from immediately deducting the sales charge by shifting his or her investment within a family of mutual funds.

Backup Withholding. In certain cases, a Fund will be required to withhold at a 24% rate and remit to the U.S. Treasury such amounts withheld from any distributions paid to a shareholder who: (i) has failed to provide a correct taxpayer identification number; (ii) is subject to backup withholding by the IRS; (iii) has failed to certify to a Fund that such shareholder is not subject to backup withholding; or (iv) has not certified that such shareholder is a U.S. person (including a U.S. resident alien). Backup withholding is not an additional tax and any amount withheld may be credited against a shareholder's U.S. federal income tax liability.

Sections 351 and 362. The Trust, on behalf of each Fund, has the right to reject an order for a purchase of shares of the Fund if the purchaser (or group of purchasers) would, upon obtaining the shares so ordered, own 80% or more of the outstanding shares of a given Fund and if, pursuant to Sections 351 and 362 of the Internal Revenue Code, that Fund would have a basis in the securities different from the market value of such securities on the date of deposit. If a Fund’s basis in such securities on the date of deposit was less than market value on such date, the Fund, upon disposition of the securities, would recognize more taxable gain or less taxable loss than if its basis in the securities had been equal to market value. It is not anticipated that the Trust will exercise the right of rejection except in a case where the Trust determines that accepting the order could result in material adverse tax consequences to a Fund or its shareholders. The Trust also has the right to require information necessary to determine beneficial share ownership for purposes of the 80% determination.

Tax-Exempt Interest Income. Dividends paid by a Fund that are properly reported as exempt-interest dividends will not be subject to regular federal income tax. Dividends paid on Fund shares that are loaned out pursuant to securities lending arrangements will not be exempt from income tax. Each Fund intends to invest its assets in a manner such that dividend distributions to its shareholders will generally be exempt from U.S. federal income taxation, including the federal AMT. In the last year of operation, when a Fund’s target date is reached, the Fund may invest in AMT-free tax-exempt municipal notes, including tax anticipation notes, revenue anticipation notes, tax and revenue anticipation notes, grant anticipation notes and bond anticipation notes; municipal commercial paper; tender option bonds and variable rate demand notes and obligations. The 3.8% Medicare contribution tax (discussed above) will not apply to exempt-interest dividends paid by a Fund.

Dividends paid by a Fund reported as exempt-interest dividends will be exempt from federal income tax (though not necessarily exempt from state and local taxation) to the extent of the Fund’s net tax-exempt income as long as 50% or more of the value of the Fund’s assets at the end of each quarter is invested in state, municipal or other bonds that are excluded from gross income for U.S. federal income tax purposes as long as the Fund properly reports such dividends as exempt-interest dividends. Exempt-interest dividends paid by a Fund allocable to interest income from the municipal bonds of a particular state may be exempt from income taxation for shareholders who are residents of such state. Exempt-interest dividends from interest from municipal bonds of other states generally are not so exempt. However, the receipt of exempt-interest dividends may require a shareholder to recharacterize a portion of certain non-taxable social security and railroad retirement benefit payments as taxable income. Shareholders should consult their own tax advisors.

Taxation of Certain Derivatives. A Fund’s transactions in zero coupon securities, non-U.S. currencies, forward contracts, options and futures contracts (including options and futures contracts on non-U.S. currencies), to the extent permitted, will be subject to special provisions of the Internal Revenue Code (including provisions relating to “hedging transactions” and “straddles”) that, among other consequences, may affect the character of gains and losses realized by the Fund (i.e., may affect whether gains or losses are ordinary or capital), accelerate recognition of income to the Fund and defer Fund losses. These rules could therefore affect the character, amount and timing of distributions to shareholders. These provisions also (a) will require the Fund to mark-to-market certain types of the positions in its portfolio (i.e., treat them as if they were closed out at the end of each year) and (b) may cause the Fund to recognize income without receiving cash with which to pay dividends or make distributions in amounts necessary to satisfy the distribution requirements for avoiding income and excise taxes. Each Fund will monitor its transactions, will make the appropriate tax elections and will make the appropriate entries in its books and records when it acquires any zero coupon security, non-U.S. currency, forward contract, option, futures contract or hedged investment in order to mitigate the effect of these rules and prevent disqualification of the Fund as a RIC.

A Fund’s investments in so-called “section 1256 contracts,” such as regulated futures contracts, most non-U.S. currency forward contracts traded in the interbank market and options on most security indexes, are subject to special tax rules. All section 1256 contracts held by the Fund at the end of its taxable year are required to be marked to their market value, and any unrealized gain or loss on those positions will be included in the Fund’s income as if each position had been sold for its fair market value at the end of the taxable year. The resulting gain or loss will be combined with any gain or loss realized by the Fund from positions in section 1256 contracts closed during the taxable year. Provided such positions were held as capital assets and were not part of a “hedging transaction” nor part of a “straddle,” 60% of the resulting net gain or loss will be treated as long-term capital gain or loss, and 40% of such net gain or loss will be treated as short-term capital gain or loss, regardless of the period of time the positions were actually held by the Fund.

As a result of entering into swap contracts, a Fund may make or receive periodic net payments. A Fund may also make or receive a payment when a swap is terminated prior to maturity through an assignment of the swap or other closing transaction. Periodic net payments will generally constitute ordinary income or deductions, while termination of a swap will generally result in capital gain or loss (which will be a long-term capital gain or loss if the Fund has been a party to the swap for more than one year). The cost of any payments made by the Fund on a swap transaction will be netted pro rata against both tax exempt and taxable gross income. With respect to certain types of swaps, a Fund may be required to currently recognize income or loss with respect to future payments on such swaps or may elect under certain circumstances to mark such swaps to market annually for tax purposes as ordinary income or loss. Periodic net payments that would otherwise constitute ordinary deductions but are allocable under the Internal Revenue Code to exempt-interest dividends will not be allowed as deductions but instead will reduce net tax-exempt income.

Market Discount. Any market discount recognized on a bond is taxable as ordinary income. A market discount bond is a bond acquired in the secondary market at a price below redemption value or adjusted issue price if issued with original issue discount (“OID”). To the extent a Fund does not include the market discount in income as it accrues, gain on the Fund’s disposition of such an obligation will be treated as ordinary income rather than capital gain to the extent of the accrued market discount.

Original Issue Discount. OID on tax-exempt bonds is recognized over the term of the bond and is tax-exempt to the holder of the bond. Special U.S. federal income tax rules apply to inflation-indexed bonds. Generally, all stated interest on such bonds is taken into income by a Fund under its regular method of accounting for interest income. The amount of a positive inflation adjustment, which results in an increase in the inflation-adjusted principal amount of the bond, is treated as original issue discount. The OID is included in a Fund’s gross income ratably during the period ending with the maturity of the bond, under the general OID inclusion rules. The amount of a Fund’s OID in a taxable year with respect to a bond will increase a Fund’s taxable income for such year without a corresponding receipt of cash, until the bond matures. As a result, a Fund may need to use other sources of cash to satisfy its distributions for such year. The amount of negative inflation adjustment, which results in a decrease in the inflation-adjusted principal amount of the bond, reduces the amount of interest (including stated, interest, OID, and market discount, if any) otherwise includible in a Fund’s income with respect to the bond for the taxable year.

but under current guidance, shareholders of a RIC are not exempted. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer’s treatment of the loss is proper. Shareholders should consult their tax advisors to determine the applicability of these regulations in light of their individual circumstances.

Taxation of Non-U.S. Shareholders. Dividends paid by a Fund to non-U.S. shareholders are generally subject to withholding tax at a 30% rate or a reduced rate specified by an applicable income tax treaty to the extent derived from investment income and short-term capital gains. Dividends paid by a Fund from net tax-exempt income or long-term capital gains are generally not subject to such withholding tax. In order to obtain a reduced rate of withholding, a non-U.S. shareholder will be required to provide an IRS Form W-8BEN or IRS Form W-8BEN-E certifying its entitlement to benefits under a treaty. The withholding tax does not apply to regular dividends paid to a non-U.S. shareholder who provides an IRS Form W-8ECI, certifying that the dividends are effectively connected with the non-U.S. shareholder’s conduct of a trade or business within the U.S. Instead, the effectively connected dividends will be subject to regular U.S. income tax as if the non-U.S. shareholder were a U.S. shareholder. A non-U.S. corporation receiving effectively connected dividends may also be subject to additional “branch profits tax” imposed at a rate of 30% (or lower treaty rate). A non-U.S. shareholder who fails to provide an IRS Form W-8BEN, IRS Form W-8BEN-E or other applicable form may be subject to backup withholding at the appropriate rate.

Properly-reported dividends are generally exempt from U.S. federal withholding tax where they (i) are paid in respect of a Fund’s “qualified net interest income” (generally, a Fund’s U.S. source interest income, other than certain contingent interest and interest from obligations of a corporation or partnership in which a Fund is at least a 10% shareholder or partner, reduced by expenses that are allocable to such income); or (ii) are paid in respect of a Fund’s “qualified short-term capital gains” (generally, the excess of a Fund’s net short-term capital gain over a Fund’s long-term capital loss for such taxable year). However, depending on its circumstances, a Fund may report all, some or none of its potentially eligible dividends as such qualified net interest income or as qualified short-term capital gains and/or treat such dividends, in whole or in part, as ineligible for this exemption from withholding. In order to qualify for this exemption from withholding, a non-U.S. shareholder will need to comply with applicable certification requirements relating to its non-U.S. status (including, in general, furnishing an IRS Form W-8BEN, IRS Form W-8BEN-E or substitute Form). In the case of shares held through an intermediary, the intermediary may withhold even if a Fund reports the payment as qualified net interest income or qualified short-term capital gain. Non-U.S. shareholders should contact their intermediaries with respect to the application of these rules to their accounts.

Distributions that a Fund reports as “short-term capital gain dividends” or “long-term capital gain dividends” will not be treated as such to a recipient foreign shareholder if the distribution is attributable to gain received from the sale or exchange of U.S. real property or an interest in a U.S. real property holding corporation and a Fund’s direct or indirect interests in U.S. real property exceeded certain levels. Instead, if the foreign shareholder has not owned more than 5% of the outstanding shares of a Fund at any time during the one year period ending on the date of distribution, such distributions will be subject to 30% withholding by a Fund and will be treated as ordinary dividends to the foreign shareholder; if the foreign shareholder owned more than 5% of the outstanding shares of a Fund at any time during the one year period ending on the date of the distribution, such distribution will be treated as real property gain subject to 21% withholding tax and could subject the foreign shareholder to U.S. filing requirements. Additionally, if a Fund’s direct or indirect interests in U.S. real property were to exceed certain levels, a foreign shareholder realizing gains upon redemption from a Fund could be subject to the 21% withholding tax and U.S. filing requirements unless more than 50% of a Fund’s shares were owned by U.S. persons at such time or unless the foreign person had not held more than 5% of a Fund’s outstanding shares throughout either such person’s holding period for the redeemed shares or, if shorter, the previous five years.

ending on the date of the distributions. Such distributions may be subject to U.S. withholding tax and may require a foreign shareholder to file a U.S. federal income tax return. In addition, sales or redemptions of shares held by certain foreign shareholders in such a Fund generally will be subject to U.S. withholding tax and generally will require the foreign shareholder to file a U.S. federal income tax return, although exceptions may apply if more than 50% of the value of the Fund’s shares are held by U.S. shareholders or the foreign shareholder selling or redeeming the shares has held no more than 5% of any class of stock of the Fund at any time during the five-year period ending on the date of the sale or redemption.

Separately, a 30% withholding tax is currently imposed on U.S.-source dividends, interest and other income items, and will be imposed on proceeds from the sale, redemption or other disposition of property producing U.S.-source dividends and interest paid after December 31, 2018, to: (i) foreign financial institutions, including non-U.S. investment funds, unless they agree to collect and disclose to the IRS information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to: (i) enter into agreements with the IRS that state that they will provide the IRS information including the names, addresses and taxpayer identification numbers of direct and indirect U.S. account holders; comply with due diligence procedures with respect to the identification of U.S. accounts; report to the IRS certain information with respect to U.S. accounts maintained; agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information; and determine certain other information as to their account holders, or (ii) in the event that an applicable intergovernmental agreement and implementing legislation are adopted, provide local revenue authorities with similar account holder information. Other foreign entities will need to provide the name, address and taxpayer identification number of each substantial U.S. owner or provide certifications of no substantial U.S. ownership, unless certain exceptions apply.

Shares of a Fund held by a non-U.S. shareholder at death will be considered situated within the U.S. and subject to the U.S. estate tax.

INTRODUCTION TO BLACKROCK

PHILOSOPHY ON CORPORATE GOVERNANCE

CORPORATE GOVERNANCE, ENGAGEMENT AND VOTING

A-3

principles inform our voting decisions in relation to specific resolutions that may appear on the agenda of a shareholder meeting in the relevant market.

The six key themes are:

•	Boards and directors
•	Auditors and audit-related issues
•	Capital structure, mergers, asset sales and other special transactions
•	Remuneration and benefits
•	Social, ethical and environmental issues
•	General corporate governance matters

Boards and directors

We expect the board of directors to promote and protect shareholder interests by:

•	establishing an appropriate corporate governance structure;
•	supporting and overseeing management in setting strategy;
•	ensuring the integrity of financial statements;
•	making decisions regarding mergers, acquisitions and disposals;
•	establishing appropriate executive compensation structures; and
•	addressing business issues including social, ethical and environmental issues when they have the potential to materially impact company reputation and performance.

•	current employment at the company or a subsidiary;

A-4

•	former employment within the past several years as an executive of the company;
•	providing substantial professional services to the company and/or members of the company’s management;
•	having had a substantial business relationship in the past three years;
•	having, or representing a shareholder with, a substantial shareholding in the company;

Oversight

BlackRock’s Equity Policy Oversight Committee (EPOC) is informed of certain aspects of the work of the Global Corporate Governance Oversight Committee and the Corporate Governance Group.

Vote execution

A-7

Conflicts management

•	BlackRock has adopted a proxy voting oversight structure whereby the Corporate Governance Committees oversee the voting decisions and other activities of the Corporate Governance Group, and particularly its activities with respect to voting in the relevant region of each Corporate Governance Committee’s jurisdiction.
•	The Corporate Governance Committees have adopted Guidelines for each region, which set forth the firm’s views with respect to certain corporate governance and other issues that typically arise in the proxy voting context. The Corporate Governance Committees receive periodic reports regarding the specific votes cast by the Corporate Governance Group and regular updates on material process issues, procedural changes and other matters of concern to the Corporate Governance Committees.
•	BlackRock’s Global Corporate Governance Oversight Committee oversees the Global Head, the Corporate Governance Group and the Corporate Governance Committees. The Global Corporate Governance Oversight Committee conducts a review, at least annually, of the proxy voting process to ensure compliance with BlackRock’s risk policies and procedures.
•	BlackRock maintains a reporting structure that separates the Global Head and Corporate Governance Group from employees with sales responsibilities. In addition, BlackRock maintains procedures intended to ensure that all engagements with corporate issuers or dissident shareholders are managed consistently and without regard to BlackRock’s relationship with the issuer of the proxy or dissident shareholder. Within the normal course of business, the Global Head or Corporate Governance Group may engage directly with BlackRock clients, and with employees with sales responsibilities, in discussions regarding general corporate governance policy matters, and to otherwise ensure that proxy-related client service levels are met. The Global Head or Corporate Governance Group does not discuss any specific voting matter with a client prior to the disclosure of the vote decision to all applicable clients after the shareholder meeting has taken place, except if the client is acting in the capacity as issuer of the proxy or dissident shareholder and is engaging through the established procedures independent of the client relationship.
•	In certain instances, BlackRock may determine to engage an independent fiduciary to vote proxies as a further safeguard to avoid potential conflicts of interest or as otherwise required by applicable law. The independent fiduciary may either vote such proxies or provide BlackRock with instructions as to how to vote such proxies. In the latter case, BlackRock votes the proxy in accordance with the independent fiduciary’s determination. Use of an independent fiduciary has been

A-8

adopted for voting the proxies related to any company that is affiliated with BlackRock or any company that includes BlackRock employees on its board of directors.

Appendix B – Description of Fixed-Income Ratings

A rating is generally assigned to a fixed-income security at the time of issuance by a credit rating agency designated as a nationally recognized statistical rating organization (“NRSRO”) by the SEC. While NRSROs may from time to time revise such ratings, they undertake no obligation to do so, and the ratings given to securities at issuance do not necessarily represent ratings which would be given to these securities on a particular subsequent date.

NRSROs may rate specific investments (e.g., bonds), issuers (e.g., corporations, governments and financial institutions) and/or programs (e.g., commercial paper programs). However, certain types of investments generally are not rated by NRSROs, such as certain government/sovereign obligations, US agency securities, commercial paper, time deposits at financial institutions, and derivative instruments such as credit default swaps. For these types of investments, as well as US Treasury securities (some of which are not rated), where a NRSRO has not rated the specific investment but has rated the investment’s issuer, program, financial institution or underlying reference asset, BFA may consider the investment to have the same NRSRO rating as its issuer, program, financial institution or underlying reference asset, as applicable. In the case of municipal securities, where one NRSRO provides multiple ratings for the same security (e.g., “underlying,” “insured” and/or “enhanced” ratings), BFA may consider the security to have the highest of the multiple ratings.

New issue securities (regardless of type) rarely are rated by a NRSRO at the time of their initial offering. Preliminary prospectuses or term sheets for new issue securities often include an expected rating for the security (as determined by the underwriter and/or issuer) or a NRSRO rating for the issuer of the security. If applicable, when deciding whether to purchase a new issue security that has not yet been rated by a NRSRO, BFA may attribute an expected rating to the security based on: (i) the expected rating of the security set forth in the preliminary prospectus or term sheet for the security; (ii) the NRSRO’s rating for the issuer of the security set forth in the preliminary prospectus or term sheet for the security; or (iii) with respect to asset-backed securities, the rating of a prior issuance having a similar structure or the same sponsor.

Where the investment objective of a Fund is to track the performance of an index that includes credit ratings eligibility criteria as part of its index methodology, a Fund may purchase any security within the index, such security having been determined by the index provider as meeting its credit ratings eligibility criteria. The credit ratings practices of an index provider may differ from BlackRock’s practices, as described above. Further, a Fund may invest, directly or indirectly, in securities that are not rated by a rating agency or securities with a credit rating that differs from the credit rating specified in its index methodology in various circumstances, including where a security is downgraded but not yet removed from an index, following the removal of a security from an index prior to its sale by the Fund or as a result of a corporate action or restructuring affecting an issuer of a security held by a Fund.

Fixed-income securities which are unrated expose the investor to risks with respect to capacity to pay interest or repay principal which are similar to the risks of lower-rated speculative bonds. Evaluation of these securities is dependent on the investment adviser’s judgment, analysis and experience in the evaluation of such securities.

Investors should note that the assignment of a rating to a security by an NRSRO may not reflect the effect of recent developments on the issuer’s ability to make interest and principal payments or on the likelihood of default.

Securities deemed to be high yield are rated below Baa3 by Moody’s and below BBB- by S&P Global Ratings and Fitch.

The descriptions below relate to general long-term and short-term obligations of an issuer.

Moody’s Ratings

Long-Term Obligations

Aaa: Obligations rated Aaa are judged to be of the highest quality, subject to the lowest level of credit risk.

Aa: Obligations rated Aa are judged to be of high quality and are subject to very low credit risk.

A: Obligations rated A are judged to be upper-medium grade and are subject to low credit risk.

Baa: Obligations rated Baa are judged to be medium-grade and subject to moderate credit risk and as such may possess certain speculative characteristics.

B-1

Ba: Obligations rated Ba are judged to be speculative and are subject to substantial credit risk.

B: Obligations rated B are considered speculative and are subject to high credit risk.

Caa: Obligations rated Caa are judged to be speculative, of poor standing and are subject to very high credit risk.

Ca: Obligations rated Ca are highly speculative and are likely in, or very near, default, with some prospect of recovery of principal and interest.

C: Obligations rated C are the lowest rated and are typically in default, with little prospect for recovery of principal or interest.

Note: Moody's appends numerical modifiers 1, 2 and 3 in each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of that generic rating category.

Absence of Rating: Where no rating has been assigned or where a rating has been withdrawn, it may be for reasons unrelated to the creditworthiness of the issue.

Should no rating be assigned, the reason may be one of the following:

1. An application was not received or accepted.

2. The issue or issuer belongs to a group of securities or entities that are not rated as a matter of policy.

3. There is a lack of essential data pertaining to the issue or issuer.

4. The issue was privately placed, in which case the rating is not published in Moody’s publications.

Withdrawal may occur if new and material circumstances arise, the effects of which preclude satisfactory analysis; if there is no longer available reasonable up-to-date data to permit a judgment to be formed; if a bond is called for redemption; or for other reasons.

Short-Term Obligations

Moody’s short-term debt ratings are opinions of the ability of issuers to honor short-term financial obligations, generally with an original maturity not exceeding thirteen months.

Moody's employs the following designations to indicate the relative repayment ability of rated issuers:

P-1: Issuers (or supporting institutions) rated Prime-1 have a superior ability to repay short-term debt obligations.

P-2: Issuers (or supporting institutions) rated Prime-2 have a strong ability to repay short-term debt obligations.

P-3: Issuers (or supporting institutions) rated Prime-3 have an acceptable ability to repay short-term obligations.

NP: Issuers (or supporting institutions) rated Not Prime do not fall within any of the Prime rating categories.

US Municipal Short-Term Debt Obligations

There are three rating categories for short-term municipal obligations that are considered investment grade and are designated as Municipal Investment Grade (MIG). In addition, those short-term obligations that are of speculative quality are designated SG, or speculative grade. MIG ratings expire at the maturity of the obligation.

MIG 1: This designation denotes superior credit quality. Excellent protection is afforded by established cash flows, highly reliable liquidity support, or demonstrated broad-based access to the market for refinancing.

MIG 2: This designation denotes strong credit quality. Margins of protection are ample, although not as large as in the preceding group.

MIG 3: This designation denotes acceptable credit quality. Liquidity and cash-flow protection may be narrow, and market access for refinancing is likely to be less well-established.

B-2

SG: This designation denotes speculative-grade credit quality. Debt instruments in this category may lack sufficient margins of protection.

S&P Global Ratings

Long-Term Obligations

AAA: An obligation rated AAA has the highest rating assigned by S&P Global Ratings. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.

AA: An obligation rated AA differs from the highest-rated obligations only to a small degree. The obligor’s capacity to meet its financial commitment is very strong.

A: An obligation rated A is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher-rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.

BBB: An obligation rated BBB exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

BB; B; CCC; CC; and C: Obligations rated BB, B, CCC, CC, and C are regarded as having significant speculative characteristics. BB indicates the least degree of speculation and C the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

BB: An obligation rated BB is less vulnerable to nonpayment than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor’s inadequate capacity to meet its financial commitment on the obligation.

B: An obligation rated B is more vulnerable to nonpayment than obligations rated BB, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor’s capacity or willingness to meet its financial commitment on the obligation.

CCC: An obligation rated CCC is currently vulnerable to nonpayment, and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.

CC: An obligation rated CC is currently highly vulnerable to nonpayment. The CC rating is used when a default has not yet occurred, but S&P Global Ratings expects default to be a virtual certainty, regardless of the anticipated time to default.

C: An obligation rated C is currently highly vulnerable to nonpayment, and the obligation is expected to have lower relative seniority or lower ultimate recovery compared to obligations that are rated higher.

D: An obligation rated D is in default or in breach of an imputed promise. For non-hybrid capital instruments, the D rating category is used when payments on an obligation are not made on the date due, unless S&P Global Ratings believes that such payments will be made within five business days in the absence of a stated grace period or within the earlier of the stated grace period or 30 calendar days. The D rating also will be used upon the filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. An obligation's rating is lowered to D if it is subject to a distressed exchange offer.

NR: NR indicates no rating has been requested, or that there is insufficient information on which to base a rating, or that S&P Global Ratings does not rate a particular obligation as a matter of policy.

Note: The ratings from AA to CCC may be modified by the addition of a plus (+) or minus (-) sign to show relative standing within the major rating categories.

Short-Term Obligations

B-3

A-1: A short-term obligation rated A-1 is rated in the highest category by S&P Global Ratings. The obligor's capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor's capacity to meet its financial commitment on these obligations is extremely strong.

A-2: A short-term obligation rated A-2 is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor's capacity to meet its financial commitment on the obligation is satisfactory.

A-3: A short-term obligation rated A-3 exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

B: A short-term obligation rated B is regarded as vulnerable and has significant speculative characteristics. The obligor currently has the capacity to meet its financial commitments; however, it faces major ongoing uncertainties which could lead to the obligor's inadequate capacity to meet its financial commitments.

C: A short-term obligation rated C is currently vulnerable to nonpayment and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation.

D: A short-term obligation rated D is in default or in breach of an imputed promise. For non-hybrid capital instruments, the D rating category is used when payments on an obligation are not made on the date due, unless S&P Global Ratings believes that such payments will be made within any stated grace period. However, any stated grace period longer than five business days will be treated as five business days. The D rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. An obligation's rating is lowered to D if it is subject to a distressed exchange offer.

Municipal Short-Term Obligations

An S&P U.S. municipal note rating reflects S&P Global Ratings opinion about the liquidity factors and market access risks unique to the notes. Notes due in three years or less will likely receive a note rating. Notes with an original maturity of more than three years will most likely receive a long-term debt rating.

SP-1: Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus (+) designation.

SP-2: Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.

SP-3: Speculative capacity to pay principal and interest.

Fitch Ratings

Long-Term Obligations

AAA: Highest credit quality. AAA ratings denote the lowest expectation of credit risk. They are assigned only in cases of exceptionally strong capacity for payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.

AA: Very high credit quality. AA ratings denote expectations of very low credit risk. They indicate very strong capacity for payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.

A: High credit quality. A ratings denote expectations of low credit risk. The capacity for payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to adverse business or economic conditions than is the case for higher ratings.

BBB: Good credit quality. BBB ratings indicate that expectations of credit risk are currently low. The capacity for payment of financial commitments is considered adequate but adverse business or economic conditions are more likely to impair this capacity.

B-4

BB: Speculative. BB ratings indicate an elevated vulnerability to credit risk, particularly in the event of adverse changes in business or economic conditions over time; however, business or financial alternatives may be available to allow financial commitments to be met.

B: Highly speculative. B ratings indicate that material credit risk is present.

CCC: Substantial credit risk. CCC ratings indicate that substantial credit risk is present.

CC: Very high levels of credit risk. CC ratings indicate very high levels of credit risk.

C: Exceptionally high levels of credit risk. C indicates exceptionally high levels of credit risk.

Defaulted obligations typically are not assigned RD or D ratings, but are instead rated in the B to C rating categories, depending upon their recovery prospects and other relevant characteristics. This approach better aligns obligations that have comparable overall expected loss but varying vulnerability to default and loss.

Note: The modifiers “+” or “-” may be appended to a rating to denote relative status within major rating categories. Such suffixes are not added to the AAA obligation rating category, or to corporate finance obligation ratings in the categories below CCC.

The subscript 'emr' is appended to a rating to denote embedded market risk which is beyond the scope of the rating. The designation is intended to make clear that the rating solely addresses the counterparty risk of the issuing bank. It is not meant to indicate any limitation in the analysis of the counterparty risk, which in all other respects follows published Fitch criteria for analyzing the issuing financial institution. Fitch does not rate these instruments where the principal is to any degree subject to market risk.

Short-Term Obligations (Corporate and Public Finance)

A short-term issuer or obligation rating is based in all cases on the short-term vulnerability to default of the rated entity or security stream and relates to the capacity to meet financial obligations in accordance with the documentation governing the relevant obligation. Short-Term Ratings are assigned to obligations whose initial maturity is viewed as “short-term” based on market convention. Typically, this means up to 13 months for corporate, sovereign, and structured obligations, and up to 36 months for obligations in U.S. public finance markets.

F1: Highest short-term credit quality. Indicates the strongest intrinsic capacity for timely payment of financial commitments; may have an added “+” to denote any exceptionally strong credit feature.

F2: Good short-term credit quality. Good intrinsic capacity for timely payment of financial commitments.

F3: Fair short-term credit quality. The intrinsic capacity for timely payment of financial commitments is adequate.

B: Speculative short-term credit quality. Minimal capacity for timely payment of financial commitments, plus heightened vulnerability to near term adverse changes in financial and economic conditions.

C: High short-term default risk. Default is a real possibility.

RD: Restricted default. Indicates an entity that has defaulted on one or more of its financial commitments, although it continues to meet other financial obligations. Typically applicable to entity ratings only.

D: Default. Indicates a broad-based default event for an entity, or the default of a short-term obligation.

Dated August 1, 2018

Fund		Ticker		Listing Exchange
iShares Russell 2500 ETF (the “Fund”)		SMMD		Cboe BZX

The Fund invests its assets in individual securities and also may invest in another iShares fund, the iShares Russell 2000 ETF (the “Underlying Fund”) as a means of obtaining exposure to securities included in the Fund's underlying index. BlackRock Fund Advisors (“BFA” or the “Investment Adviser”), an indirect wholly-owned subsidiary of BlackRock, Inc., serves as investment adviser to the Fund and also serves as investment adviser to the Underlying Fund. References to the investments and risks of the Fund, unless otherwise indicated, should be understood as references to the investments and risks of both the Fund and the Underlying Fund.

The Prospectus for the Fund is dated August 1, 2018, as amended and supplemented from time to time. Capitalized terms used herein that are not defined have the same meaning as in the Prospectus, unless otherwise noted. A copy of the Prospectus for the Fund may be obtained without charge by writing to the Trust’s distributor, BlackRock Investments, LLC (the “Distributor” or “BRIL”), 1 University Square Drive, Princeton, NJ 08540, calling 1-800-iShares (1-800-474-2737) or visiting www.iShares.com. The Fund's Prospectus is incorporated by reference into this SAI.

iShares^® and BlackRock^® are registered trademarks of BlackRock Fund Advisors and its affiliates.

General Description of the Trust and the Fund

The Fund is managed by BFA, an indirect wholly-owned subsidiary of BlackRock, Inc., and generally seeks to track the investment results of the specific benchmark index identified in the Fund's Prospectus (the “Underlying Index”).

The Fund offers and issues shares at their net asset value per share (“NAV”) only in aggregations of a specified number of shares (each, a “Creation Unit”), generally in exchange for a designated portfolio of securities (including any portion of such securities for which cash may be substituted) included in its Underlying Index (the “Deposit Securities”), together with the deposit of a specified cash payment (the “Cash Component”). Shares of the Fund are listed and trade on Cboe BZX Exchange, Inc. (the “Listing Exchange” or “Cboe BZX”) (formerly known as BATS Exchange, Inc.), a national securities exchange. Shares of the Fund are traded in the secondary market and elsewhere at market prices that may be at, above or below the Fund's NAV. Shares are redeemable only in Creation Units by Authorized Participants (as defined in the Portfolio Holdings Information section of this SAI), and, generally, in exchange for portfolio securities and a Cash Amount (as defined in the Redemption of Creation Units section of this SAI). Creation Units typically are a specified number of shares, generally 50,000 or multiples thereof.

Exchange Listing and Trading

As in the case of other publicly-traded securities, when you buy or sell shares of the Fund through a broker, you may incur a brokerage commission determined by that broker, as well as other charges.

In order to provide additional information regarding the indicative value of shares of the Fund, the Listing Exchange or a market data vendor disseminates information every 15 seconds through the facilities of the Consolidated Tape Association, or through other widely disseminated means, an updated indicative optimized portfolio value (“IOPV”) for the Fund as calculated by an information provider or market data vendor. The Trust is not involved in or responsible for any aspect of the calculation or dissemination of the IOPV and makes no representation or warranty as to the accuracy of the IOPV.

An IOPV has an equity securities component and a cash component. The equity securities values included in an IOPV are the values of the Deposit Securities for the Fund. While the IOPV reflects the current value of the Deposit Securities required to be deposited in connection with the purchase of a Creation Unit, it does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time because the current portfolio of the Fund may include securities that are not a part of the current Deposit Securities. Therefore, the Fund’s IOPV disseminated during the Listing Exchange trading hours should not be viewed as a real-time update of the Fund’s NAV, which is calculated only once a day.

Investment Strategies and Risks of the Fund

The Fund is managed by BFA and generally seeks to meet its investment objective by investing in securities of its Underlying Index either directly or through holding shares of the Underlying Fund. Because the Fund may periodically obtain its exposure to the securities in the Underlying Index by investing in the Underlying Fund, shareholders should be aware that the Fund’s exposure to the types of investments discussed below may be obtained by the Fund through an investment in the Underlying Fund. However, BFA is not required to invest any portion, or any particular percentage, of the Fund’s assets in the Underlying Fund. The Fund operates as an index fund and is not actively managed. Adverse performance of a security in the Fund’s portfolio will ordinarily not result in the elimination of the security from the Fund’s portfolio.

The Fund engages in representative sampling, which is investing in a sample of securities selected by BFA to have a collective investment profile similar to that of the Fund's Underlying Index. Securities selected have aggregate investment characteristics (based on market capitalization and industry weightings), fundamental characteristics (such as return variability, earnings valuation and yield) and liquidity measures similar to those of the Underlying Index. A fund that uses representative sampling generally does not hold all of the securities that are in its underlying index.

Although the Fund does not seek leveraged returns, certain instruments used by the Fund may have a leveraging effect as described below.

investment objectives and policies. However, a breach of any such covenants not cured within the specified cure period may result in acceleration of outstanding indebtedness and require the Fund to dispose of portfolio investments at a time when it may be disadvantageous to do so.

Diversification Status. The Fund is classified as a diversified fund under the 1940 Act. This means that the Fund may not purchase securities of an issuer (other than (i) obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities and (ii) securities of other investment companies) if, with respect to 75% of its total assets, (a) more than 5% of the Fund’s total assets would be invested in securities of that issuer or (b) the Fund would hold more than 10% of the outstanding voting securities of that issuer. With respect to the remaining 25% of its total assets, the Fund may invest more than 5% of its assets in one issuer. Under the 1940 Act, the Fund cannot change its classification from diversified to non-diversified without shareholder approval.

Futures, Options on Futures and Securities Options. Futures contracts, options on futures and securities options may be used by the Fund to simulate investment in its Underlying Index, to facilitate trading or to reduce transaction costs. The Fund or the Underlying Fund may enter into futures contracts and options on futures that are traded on a U.S. or non-U.S. futures exchange. The Fund or the Underlying Fund will not use futures, options on futures or securities options for speculative purposes. The Fund intends to use futures and options on futures in accordance with Rule 4.5 of the Commodity Futures Trading Commission (the “CFTC”) promulgated under the Commodity Exchange Act (“CEA”). BFA, with respect to the Fund, has claimed an exclusion from the definition of the term “commodity pool operator” in accordance with Rule 4.5 so that BFA, with respect to the Fund, is not subject to registration or regulation as a commodity pool operator under the CEA. See the Regulation Regarding Derivatives section of this SAI for more information.

Futures contracts provide for the future sale by one party and purchase by another party of a specified amount of a specific instrument or index at a specified future time and at a specified price. Stock index contracts are based on investments that reflect the market value of common stock of the firms included in the investments. The Fund or the Underlying Fund may enter into futures contracts to purchase securities indexes when BFA anticipates purchasing the underlying securities and believes prices will rise before the purchase will be made. Upon entering into a futures contract, the Fund or the Underlying Fund will be required to deposit with the broker an amount of cash or cash equivalents known as “initial margin,” which is similar to a performance bond or good faith deposit on the contract and is returned to the Fund or the Underlying Fund upon termination of the futures contract if all contractual obligations have been satisfied. Subsequent payments, known as “variation margin,” will be made to and from the broker daily as the price of the instrument or index underlying the futures contract fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as “marking-to-market.” At any time prior to the expiration of a futures contract, the Fund or the Underlying Fund may elect to close the position by taking an opposite position, which will operate to terminate the Fund’s or the Underlying Fund's existing position in the contract. To the extent required by law, the Fund will segregate liquid assets in an amount equal to its delivery obligations under the futures contracts. An option on a futures contract, as contrasted with a direct investment in such a contract, gives the purchaser the right, but no obligation, in return for the premium paid, to assume a position in the underlying futures contract at a specified exercise price at any time prior to the expiration date of the option. Upon exercise of an option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer’s futures margin account that represents the amount by which the market price of the futures contract exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the futures contract. The potential for loss related to the purchase of an option on a futures contract is limited to the premium paid for the option plus transaction costs. Because the value of the option is fixed at the point of sale, there are no daily cash payments by the purchaser to reflect changes in the value of the underlying contract; however, the value of the option changes daily and that change would be reflected in the NAV of the Fund. The potential for loss related to writing call options is unlimited. The potential for loss related to writing put options is limited to the agreed-upon price per share, also known as the “strike price,” less the premium received from writing the put. The Fund or the Underlying Fund may purchase and write put and call options on futures contracts that are traded on an exchange as a hedge against changes in value of its

portfolio securities or in anticipation of the purchase of securities, and may enter into closing transactions with respect to such options to terminate existing positions. There is no guarantee that such closing transactions can be effected.

Securities options may be used by the Fund to obtain access to securities in the Underlying Index or to dispose of securities in the Underlying Index at favorable prices, to invest cash in a securities index that offers similar exposure to that provided by the Underlying Index or otherwise to achieve the Fund’s objective of tracking the Underlying Index. A call option gives a holder the right to purchase a specific security at a specified price (“exercise price”) within a specified period of time. A put option gives a holder the right to sell a specific security at an exercise price within a specified period of time. The initial purchaser of a call option pays the “writer” a premium, which is paid at the time of purchase and is retained by the writer whether or not such option is exercised. The Fund or the Underlying Fund may purchase put options to hedge its portfolio against the risk of a decline in the market value of securities held and may purchase call options to hedge against an increase in the price of securities it is committed to purchase. The Fund or the Underlying Fund may write put and call options along with a long position in options to increase its ability to hedge against a change in the market value of the securities it holds or is committed to purchase. The Fund or the Underlying Fund may purchase or sell securities options on a U.S. or non-U.S. securities exchange or in the OTC market through a transaction with a dealer. Options on a securities index are typically settled on a net basis based on the appreciation or depreciation of the index level over the strike price. Options on single name securities may be cash- or physically-settled, depending upon the market in which they are traded. Options may be structured so as to be exercisable only on certain dates or on a daily basis. Options may also be structured to have conditions to exercise (i.e., “Knock-in Events”) or conditions that trigger termination (i.e., “Knock-out Events”). Investments in futures contracts and other investments that contain leverage may require the Fund to maintain liquid assets in an amount equal to its delivery obligations under these contracts and other investments. Generally, the Fund maintains an amount of liquid assets equal to its obligations relative to the position involved, adjusted daily on a marked-to-market basis. With respect to futures contracts that are contractually required to “cash-settle,” the Fund maintains liquid assets in an amount at least equal to the Fund’s or the Underlying Fund's daily marked-to-market obligation (i.e., the Fund’s or the Underlying Fund's daily net liability, if any), rather than the contracts’ notional value (i.e., the value of the underlying asset). By maintaining assets equal to its net obligation under cash-settled futures contracts, the Fund or the Underlying Fund may employ leverage to a greater extent than if the Fund were required to set aside assets equal to the futures contracts’ full notional value. The Fund or the Underlying Fund bases its asset maintenance policies on methods permitted by the SEC and its staff and may modify these policies in the future to comply with any changes in the guidance articulated from time to time by the SEC or its staff. Changes in SEC guidance regarding the use of derivatives by registered investment companies may adversely impact the Fund’s or the Underlying Fund's ability to invest in futures, options or other derivatives or make investments in such instruments more expensive.

Illiquid Securities. The Fund and the Underlying Fund each may invest up to an aggregate amount of 15% of its net assets in illiquid securities (calculated at the time of investment). Illiquid securities may include securities subject to contractual or other restrictions on resale and other instruments that lack readily available markets, as determined in accordance with SEC staff guidance. The liquidity of a security relates to the ability to readily dispose of the security and the price to be obtained upon disposition of the security, which may be lower than the price that would be obtained for a comparable, more liquid security. Illiquid securities may trade at a discount to comparable, more liquid securities and the Fund or the Underlying Fund may not be able to dispose of illiquid securities in a timely fashion or at their expected prices.

Investments in Underlying Funds and Other Investment Companies. To implement its strategy, the Fund may invest some or all of its assets in the Underlying Fund. The Underlying Fund generally invests directly in portfolio securities. The Fund may also invest in other investment companies, including exchange-traded funds (commonly referred to as “ETFs”) that are not iShares ETFs, to the extent permitted by law.

Lending Portfolio Securities. The Fund and the Underlying Fund may lend portfolio securities to certain borrowers that BFA determines to be creditworthy, including borrowers affiliated with BFA. The borrowers provide collateral that is maintained in an amount at least equal to the current market value of the securities loaned. No securities loan shall be made on behalf of the Fund or the Underlying Fund if, as a result, the aggregate value of all securities loaned by the Fund or the Underlying Fund exceeds one-third of the value of the Fund's or the Underlying Fund's total assets (including the value of the collateral received). The Fund or the Underlying Fund may terminate a loan at any time and obtain the return of the securities loaned. The Fund or the Underlying Fund receives, by way of substitute payment, the value of any interest or cash or non-cash distributions paid on the loaned securities that it would have received if the securities were not on loan.

With respect to loans that are collateralized by cash, the borrower may be entitled to receive a fee based on the amount of cash collateral. The Fund or the Underlying Fund is typically compensated by the difference between the amount earned on the reinvestment of cash collateral and the fee paid to the borrower. In the case of collateral other than cash, the Fund or the Underlying Fund is typically compensated by a fee paid by the borrower equal to a percentage of the market value of the loaned securities. Any cash collateral may be reinvested in certain short-term instruments either directly on behalf of the lending Fund or through one or more joint accounts or money market funds, including those affiliated with BFA; such investments are subject to investment risk. Other investment companies in which the Fund or the Underlying Fund invests can be expected to incur fees and expenses for operations, such as investment advisory and administration fees, that would be in addition to those incurred by the Fund or the Underlying Fund.

The Fund conducts its securities lending pursuant to an exemptive order from the SEC permitting it to lend portfolio securities to borrowers affiliated with the Fund and to retain an affiliate of the Fund to act as securities lending agent. To the extent that the Fund or the Underlying Fund engages in securities lending, BlackRock Institutional Trust Company, N.A. (“BTC”) acts as securities lending agent for the Fund and the Underlying Fund, subject to the overall supervision of BFA. BTC administers the lending program in accordance with guidelines approved by the Trust's Board of Trustees (the “Board,” the trustees of which are the “Trustees”).

Securities lending involves exposure to certain risks, including operational risk (i.e., the risk of losses resulting from problems in the settlement and accounting process), “gap” risk (i.e., the risk of a mismatch between the return on cash collateral reinvestments and the fees the Fund or the Underlying Fund has agreed to pay a borrower), and credit, legal, counterparty and market risk. If a securities lending counterparty were to default, the Fund or the Underlying Fund would be subject to the risk of a possible delay in receiving collateral or in recovering the loaned securities, or to a possible loss of rights in the collateral. In the event a borrower does not return the Fund’s or the Underlying Fund's securities as agreed, the Fund or the Underlying Fund may experience losses if the proceeds received from liquidating the collateral do not at least equal the value of the loaned security at the time the collateral is liquidated, plus the transaction costs incurred in purchasing replacement securities. This event could trigger adverse tax consequences for the Fund and the Underlying Fund. The Fund or the Underlying Fund could lose money if its short-term investment of the collateral declines in value over the period of the loan. Substitute payments for dividends received by the Fund or the Underlying Fund for securities loaned out by the Fund or the Underlying Fund will not be considered qualified dividend income. BTC will take into account the tax effects on shareholders caused by this difference in connection with the Fund’s securities lending program. Substitute payments received on tax-exempt securities loaned out will not be tax-exempt income.

Non-U.S. Securities. The Fund, either directly or through its investments in the Underlying Fund, may purchase publicly-traded common stocks of non-U.S. issuers. To the extent the Fund invests in stocks of non-U.S. issuers, the Fund's investment in such stocks may be in the form of American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) and European Depositary Receipts (“EDRs”) (collectively, “depositary receipts”). Depositary receipts are receipts, typically issued by a bank or trust issuer, which evidence ownership of underlying securities issued by a non-U.S. issuer. Depositary receipts may not necessarily be denominated in the same currency as their underlying securities. ADRs typically are issued by an American bank or trust company and evidence ownership of underlying securities issued by a foreign corporation. EDRs, which are sometimes referred to as Continental Depositary Receipts, are receipts issued in Europe, typically by foreign banks and trust companies, that evidence ownership of either foreign or domestic underlying securities. GDRs are depositary receipts structured like global debt issues to facilitate trading on an international basis. Generally, ADRs, issued in registered form, are designed for use in the U.S. securities markets, and EDRs, issued in bearer form, are designed for use in European securities markets. GDRs are tradable both in the U.S. and in Europe and are designed for use throughout the world.

generally expose investors to greater risks than sponsored programs and do not provide holders with many of the shareholder benefits that come from investing in a sponsored depositary receipts.

Investing in the securities of non-U.S. issuers involves special risks and considerations not typically associated with investing in U.S. issuers. These include differences in accounting, auditing and financial reporting standards; the possibility of expropriation or confiscatory taxation; adverse changes in investment or exchange control regulations; political instability, which could affect U.S. investments in non-U.S. countries; and potential restrictions on the flow of international capital. Non-U.S. issuers may be subject to less governmental regulation than U.S. issuers. Moreover, individual non-U.S. economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product (“GDP”), rate of inflation, capital reinvestment, resource self-sufficiency and balance of payment positions.

Regulation Regarding Derivatives. The CFTC subjects advisers to registered investment companies to regulation by the CFTC if a fund that is advised by the adviser either (i) invests, directly or indirectly, more than a prescribed level of its liquidation value in CFTC-regulated futures, options and swaps (“CFTC Derivatives”), or (ii) markets itself as providing investment exposure to such instruments. The CFTC also subjects advisers to registered investment companies to regulation by the CFTC if the registered investment company invests in one or more commodity pools. To the extent the Fund uses CFTC Derivatives, it intends to do so below such prescribed levels and intends not to market itself as a “commodity pool” or a vehicle for trading such instruments.

The Fund may also have investments in “underlying funds” (and such underlying funds themselves may invest in underlying funds) not advised by BFA (which for purposes of the no-action letter referenced below may include certain securitized vehicles, mortgage real estate investment trusts (“REITs”) and/or investment companies that may invest in CFTC Derivatives), and therefore may be viewed by the CFTC as commodity pools. BFA has no transparency into the holdings of these underlying funds because they are not advised by BFA. To address this issue of lack of transparency, the CFTC staff issued a no-action letter on November 29, 2012 permitting the adviser of a fund that invests in such underlying funds and that would otherwise have filed a claim of exclusion pursuant to CFTC Rule 4.5 to delay registration as a “commodity pool operator” until six months from the date on which the CFTC issues additional guidance on the treatment of CFTC Derivatives held by underlying funds. BFA, the adviser of the Fund, has filed a claim with the CFTC for such Fund to rely on this no-action relief. Accordingly, BFA is not currently subject to registration or regulation as a “commodity pool operator” under the CEA in respect of such Fund.

Derivative contracts, including, without limitation, swaps, currency forwards, and non-deliverable forwards, are subject to regulation under the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”) in the U.S. and under comparable regimes in Europe, Asia and other non-U.S. jurisdictions. Swaps, non-deliverable forwards and certain other derivatives traded in the OTC market are subject to variation margin requirements, and initial margining requirements will be phased in through 2020. Implementation of the margining and other provisions of the Dodd-Frank Act regarding clearing, mandatory trading, reporting and documentation of swaps and other derivatives have impacted and may continue to impact the costs to the Fund of trading these instruments and, as a result, may affect returns to investors in the Fund.

As a result of regulatory requirements under the 1940 Act, the Fund is required to maintain an amount of liquid assets, accrued on a daily basis, having an aggregate value at least equal to the value of the Fund’s obligations under the applicable derivatives contract. To the extent that derivatives contracts are settled on a physical basis, the Fund will generally be required to maintain an amount of liquid assets equal to the notional value of the contract. On the other hand, in connection with derivatives contracts that are performed on a net basis, the Fund will generally be required to maintain liquid assets, accrued daily, equal only to the accrued excess, if any, of the Fund’s obligations over those of its counterparty under the contract. Accordingly, reliance by the Fund on physically-settled derivatives contracts may adversely impact investors by requiring the Fund to set aside a greater amount of liquid assets than would generally be required if the Fund were relying on cash-settled derivatives contracts.

Repurchase Agreements. A repurchase agreement is an instrument under which the purchaser (i.e., the Fund or the Underlying Fund) acquires the security and the seller agrees, at the time of the sale, to repurchase the security at a mutually agreed-upon time and price, thereby determining the yield during the purchaser’s holding period. Repurchase agreements may be construed to be collateralized loans by the purchaser to the seller secured by the securities transferred to the purchaser. If a repurchase agreement is construed to be a collateralized loan, the underlying securities will not be considered

to be owned by the Fund or the Underlying Fund but only to constitute collateral for the seller’s obligation to pay the repurchase price, and, in the event of a default by the seller, the Fund may suffer time delays and incur costs or losses in connection with the disposition of the collateral.

Repurchase agreements pose certain risks for the Fund or the Underlying Fund, should it decide to utilize them. Such risks are not unique to the Fund, but are inherent in repurchase agreements. The Fund seeks to minimize such risks, but because of the inherent legal uncertainties involved in repurchase agreements, such risks cannot be eliminated. Lower quality collateral and collateral with a longer maturity may be subject to greater price fluctuations than higher quality collateral and collateral with a shorter maturity. If the repurchase agreement counterparty were to default, lower quality collateral may be more difficult to liquidate than higher quality collateral. Should the counterparty default and the amount of collateral not be sufficient to cover the counterparty’s repurchase obligation, the Fund or the Underlying Fund would likely retain the status of an unsecured creditor of the counterparty (i.e., the position the Fund or the Underlying Fund would normally be in if it were to hold, pursuant to its investment policies, other unsecured debt securities of the defaulting counterparty) with respect to the amount of the shortfall. As an unsecured creditor, the Fund or the Underlying Fund would be at risk of losing some or all of the principal and income involved in the transaction.

Reverse Repurchase Agreements. Reverse repurchase agreements involve the sale of securities with an agreement to repurchase the securities at an agreed-upon price, date and interest payment and have the characteristics of borrowing. Generally, the effect of such transactions is that the Fund or the Underlying Fund can recover all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement, while in many cases the Fund or the Underlying Fund is able to keep some of the interest income associated with those securities. Such transactions are advantageous only if the Fund or the Underlying Fund has an opportunity to earn a rate of interest on the cash derived from these transactions that is greater than the interest cost of obtaining the same amount of cash. Opportunities to realize earnings from the use of the proceeds equal to or greater than the interest required to be paid may not always be available, and the Fund or the Underlying Fund intends to use the reverse repurchase technique only when BFA believes it will be advantageous to the Fund. The use of reverse repurchase agreements may exaggerate any increase or decrease in the value of the Fund’s or the Underlying Fund's assets. The Fund’s or the Underlying Fund's exposure to reverse repurchase agreements will be covered by liquid assets having a value equal to or greater than the Fund’s obligations under such commitments. The use of reverse repurchase agreements is a form of leverage, and the proceeds obtained by the Fund through reverse repurchase agreements may be invested in additional securities.

Securities of Investment Companies. The Fund and the Underlying Fund may invest in the securities of other investment companies (including money market funds) to the extent permitted by law. Pursuant to the 1940 Act, the Fund’s or the Underlying Fund's investment in registered investment companies is generally limited to, subject to certain exceptions: (i) 3% of the total outstanding voting stock of any one investment company; (ii) 5% of the Fund’s or the Underlying Fund's total assets with respect to any one investment company; and (iii) 10% of the Fund’s or the Underlying Fund's total assets with respect to investment companies in the aggregate. To the extent allowed by law or regulation, the Fund and the Underlying Fund intends from time to time to invest its assets in the securities of investment companies, including, but not limited to, money market funds, including those advised by or otherwise affiliated with BFA, in excess of the general limits discussed above. Other investment companies in which the Fund and the Underlying Fund may invest can be expected to incur fees and expenses for operations, such as investment advisory and administration fees, which would be in addition to those incurred by the Fund and the Underlying Fund. Pursuant to guidance issued by the SEC staff, fees and expenses of money market funds used for cash collateral received in connection with loans of securities are not treated as Acquired Fund Fees and Expenses, which reflect the Fund’s pro rata share of the fees and expenses incurred by investing in other investment companies (as disclosed in the Prospectus, as applicable).

Short-Term Instruments and Temporary Investments. The Fund and the Underlying Fund may invest in short-term instruments, including money market instruments, on an ongoing basis to provide liquidity or for other reasons. Money market instruments are generally short-term investments that may include, but are not limited to: (i) shares of money market funds (including those advised by BFA or otherwise affiliated with BFA); (ii) obligations issued or guaranteed by the U.S.

government, its agencies or instrumentalities (including government-sponsored enterprises); (iii) negotiable certificates of deposit (“CDs”), bankers’ acceptances, fixed-time deposits and other obligations of U.S. and non-U.S. banks (including non-U.S. branches) and similar institutions; (iv) commercial paper rated, at the date of purchase, “Prime-1” by Moody's^® Investors Service, Inc., “F-1” by Fitch Ratings, Inc., or “A-1” by Standard & Poor's^® Financial Services LLC, a subsidiary of S&P Global, Inc., or if unrated, of comparable quality as determined by BFA; (v) non-convertible corporate debt securities (e.g., bonds and debentures) with remaining maturities at the date of purchase of not more than 397 days and that have been determined to present minimal credit risks, in accordance with the requirements set forth in Rule 2a-7 under the 1940 Act; (vi) repurchase agreements; and (vii) short-term U.S. dollar-denominated obligations of non-U.S. banks (including U.S. branches) that, in the opinion of BFA, are of comparable quality to obligations of U.S. banks that may be purchased by the Fund. Any of these instruments may be purchased on a current or forward-settled basis. Time deposits are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates. Bankers’ acceptances are time drafts drawn on commercial banks by borrowers, usually in connection with international transactions.

The Fund or Underlying Fund may enter into currency, interest rate or index swaps. The use of currency, interest rate and index swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. These transactions generally do not involve the delivery of securities or other underlying assets.

Future Developments. The Board may, in the future, authorize the Fund or the Underlying Fund to invest in securities contracts and investments, other than those listed in this SAI and in the Prospectus, provided they are consistent with the Fund's or Underlying Fund's investment objective and do not violate any of its investment restrictions or policies.

General Considerations and Risks

A discussion of some of the principal risks associated with an investment in the Fund is contained in the Prospectus. Because the Fund expects to obtain its exposure to the securities in the Underlying Index substantially through its investment in the Underlying Fund, shareholders should be aware that the risks of investment in particular types of securities, economic sectors and geographic locations discussed below may be borne by the Fund through its investment in the Underlying Fund. Through its investment in the Underlying Fund, the Fund will also bear the risks described below associated with the Underlying Fund's use of portfolio management techniques, such as borrowing arrangements and use of derivatives, in addition to the risks associated with those activities if the Fund engages in them directly.

An investment in the Fund should be made with an understanding that the value of the Fund’s portfolio securities, including its investment in the Underlying Fund, may fluctuate in accordance with changes in the financial condition of the issuers of the portfolio securities, the value of preferred or common stocks in general, and other factors that affect the market.

Borrowing Risk. Borrowing may exaggerate changes in the net asset value of Fund shares and in the return on the Fund’s portfolio. Borrowing will cost the Fund interest expense and other fees. The costs of borrowing may reduce the Fund’s return. Borrowing may cause the Fund to liquidate positions when it may not be advantageous to do so to satisfy its obligations.

Risk of Equity Securities. An investment in the Fund should be made with an understanding of the risks inherent in an investment in equity securities, including the risk that the financial condition of issuers may become impaired or that the general condition of stock markets may deteriorate (either of which may cause a decrease in the value of the portfolio securities and thus in the value of shares of the Fund). Common stocks are susceptible to general stock market fluctuations and to increases and decreases in value as market confidence and perceptions of their issuers change. These investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies, inflation and interest rates, economic expansion or contraction, and global or regional political, economic or banking crises. Holders of common stocks incur more risks than holders of preferred stocks and debt obligations because common stockholders generally have rights to receive payments from stock issuers that are inferior to the rights of creditors, or holders of debt obligations or preferred stocks. Further, unlike debt securities, which typically have a stated principal amount payable at maturity (the value of which, however, is subject to market fluctuations prior to maturity), or preferred stocks, which typically have a liquidation preference and which may have stated optional or mandatory redemption provisions, common stocks have neither a fixed principal amount nor a maturity date. In addition, issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock price to decline.

Fund’s shares will be adversely affected if trading markets for the Fund’s portfolio securities are limited or absent, or if bid/ask spreads are wide.

Risk of Swap Agreements. The risk of loss with respect to swaps is generally limited to the net amount of payments that the Fund is contractually obligated to make. Swap agreements are subject to the risk that the swap counterparty will default on its obligations. If such a default occurs, the Fund will have contractual remedies pursuant to the agreements related to the transaction. However, such remedies may be subject to bankruptcy and insolvency laws, which could affect the Fund’s rights as a creditor (e.g., the Fund may not receive the net amount of payments that it is contractually entitled to receive).

business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it more difficult for the Fund to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments.

Risk of Investing in Small-Capitalization Companies. Stock prices of small-capitalization companies may be more volatile than those of larger companies, and, therefore, the Fund's or the Underlying Fund's share price may be more volatile than that of funds that invest a larger percentage of their assets in stocks issued by large-capitalization or mid-capitalization companies. Stock prices of small-capitalization companies are generally more vulnerable than those of large-capitalization or mid-capitalization companies to adverse business and economic developments. The stocks of small-capitalization companies may be thinly traded, making it difficult for the Fund to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making them more vulnerable to loss of personnel. Small-capitalization companies also normally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments concerning their products.

Risk of Investing in the Energy Sector. Companies in the energy sector are strongly affected by the levels and volatility of global energy prices, energy supply and demand, government regulations and policies, energy production and conservation efforts, technological change, development of alternative energy sources, and other factors that they cannot control. These companies may also lack resources and have limited business lines. Energy companies may have relatively high levels of debt and may be more likely to restructure their businesses if there are downturns in certain energy markets or in the global economy. If an energy company in the Fund's portfolio becomes distressed, the Fund could lose all or a substantial portion of its investment.

and may face future government-imposed restrictions on their businesses or increased government intervention. In addition, there is no guarantee that governments will provide any such relief in the future. These actions may cause the securities of many companies in the financials sector to decline in value.

Risk of Investing in the Producer Durables Industry. The producer durables industry includes companies involved in the design, manufacture or distribution of industrial durables such as electrical equipment and components, industrial products, and housing and telecommunications equipment. These companies may be affected by changes in domestic and international economies and politics, consolidation, and excess capacity. Companies in the producer durables industry face intense competition, which may have an adverse effect on their profitability. The success of companies in the producer durables industry may be strongly affected by changes in consumer demands, spending, tastes and preferences. Companies in the producer durables industry may be dependent on outside financing, which may be difficult to obtain. Producer durables companies may be unable to protect their intellectual property rights or may be liable for infringing the intellectual

property rights of others. In addition, these companies may be significantly affected by other factors such as economic cycles, rapid technical obsolescence, government regulations, labor relations, delays in modernization, overall capital spending levels and product liability lawsuits.

Proxy Voting Policy

proxy voting activity that might stem from any relationship between the issuer of a proxy (or any dissident shareholder) and BFA, BFA’s affiliates, the Fund or the Fund’s affiliates. Most conflicts are managed through a structural separation of BFA’s Corporate Governance Group from BFA’s employees with sales and client responsibilities. In addition, BFA maintains procedures to ensure that all engagements with corporate issuers or dissident shareholders are managed consistently and without regard to BFA’s relationship with the issuer of the proxy or the dissident shareholder. In certain instances, BFA may determine to engage an independent fiduciary to vote proxies as a further safeguard to avoid potential conflicts of interest or as otherwise required by applicable law. Copies of the Fund's Proxy Voting Policy and the BlackRock Proxy Voting Guidelines are attached as Appendix A.

Information with respect to how BFA voted proxies relating to the Fund's portfolio securities during the 12-month period ended June 30 is available: (i) without charge, upon request, by calling 1-800-iShares (1-800-474-2737) or through the Fund's website at www.iShares.com; and (ii) on the SEC’s website at www.sec.gov.

Portfolio Holdings Information

Each business day, the Fund's portfolio holdings information is provided to the Distributor or other agent for dissemination through the facilities of the NSCC and/or other fee-based subscription services to NSCC members and/or subscribers to those other fee-based subscription services, including market makers and Authorized Participants, and to entities that publish and/or analyze such information in connection with the process of purchasing or redeeming Creation Units or trading shares of the Fund in the secondary market or evaluating such potential transactions. This information typically reflects the Fund’s anticipated holdings on the following business day.

Daily access to information concerning the Fund's portfolio holdings is permitted: (i) to certain personnel of those service providers that are involved in portfolio management and providing administrative, operational, risk management, or other support to portfolio management; and (ii) to other personnel of BFA, the Distributor and their affiliates, and the administrator, custodian and fund accountant who deal directly with, or assist in, functions related to investment management, distribution, administration, custody, securities lending and fund accounting, as may be necessary to conduct business in the ordinary course in a manner consistent with federal securities laws and regulations thereunder. In addition, the Fund discloses its fixed-income and/or equity portfolio holdings daily at www.iShares.com. More information about this disclosure is available at www.iShares.com.

The Fund discloses its complete portfolio holdings schedule in public filings with the SEC within 70 days of the end of the second and fourth fiscal quarters and within 60 days of the end of the first and third fiscal quarters and will provide such information to shareholders as required by federal securities laws and regulations thereunder. The Fund may, however, voluntarily disclose all or part of its portfolio holdings other than in connection with the creation/redemption process, as discussed above, in advance of required filings with the SEC, provided that such information is made generally available to all shareholders and other interested parties in a manner that is consistent with the above policy for disclosure of portfolio holdings information. Such information may be made available through a publicly available website or other means that make the information available to all likely interested parties contemporaneously.

The Board reviews the policy and procedures for disclosure of portfolio holdings information at least annually.

Construction and Maintenance of the Underlying Index

A description of the Underlying Index is provided below.

The Russell Indexes

Component Selection Criteria. Generally, the securities in the Russell indexes (sometimes referred to as the “components”) are reviewed and reconstituted annually, typically after the close on the last Friday in June to reflect changes in the marketplace. However, the Underlying Index will be reviewed and reconstituted annually in September using data at the close of the last business day of August. The Russell Top 200^® Index, Russell 2000^® Index, Russell 1000^® Index and the Russell 2500^TMIndex are subsets of the Russell 3000^® Index. The starting universe for the Russell 3000^® Index includes all issuers listed on a U.S. Exchange that are either U.S. incorporated or incorporated in certain non-U.S. jurisdictions as Benefit-Driven Incorporations (typically tax benefit incorporations), subject to the following rules and exceptions:

•	stocks must trade at or above $1.00 on the last business day of August to be eligible for inclusion. If a stock in the index has a price lower than $1, it can remain in the index if the average price for the month is greater than $1;
•	for ranking and membership determination, all common share classes for a single company are combined to determine total market capitalization;
•	in cases where there are multiple common stock share classes and the share classes act independently of each other, each class is considered for inclusion separately; and
•	also excluded are preferred and convertible preferred stock, participating preferred stock, redeemable shares, warrants and rights, trust receipts, royalty trusts, limited liability issuers, OTC bulletin boards and pink sheet stocks, mutual funds, limited partnerships, and foreign stocks.

All eligible securities are sorted by decreasing total market capitalization to determine index eligibility.

For all Russell indexes, the weights of component issuers are adjusted based on available float-weighted capitalization according to the market value of their available outstanding shares. The impact of a component’s price change is proportional to the issuer’s total market value, which is the share price times the number of shares available. Each Russell index is adjusted to reflect changes in capitalization resulting from mergers, acquisitions, stock rights, substitutions and other capital events.

Frank Russell Company uses a probability measure to assign stocks to the growth and value style indexes. The probability measure is used to indicate the degree of certainty that a stock is value or growth, based on three fundamental indicators: relative price-to-book ratio, Institutional Brokers’ Estimate System forecast medium-term growth (2 years) and sales per share historical growth (5 years). This method allows stocks to be represented as having both growth and value characteristics, while preserving the additive nature of the indexes. As a result, a stock may be a component of a Russell growth style index and also a component of the corresponding value style index, although the stock would likely have a different weight in each index.

Issue Changes. Securities that leave the Russell indexes between reconstitution dates are not replaced. Thus, the number of securities in the investments over the year will fluctuate according to corporate activity. When a stock is acquired, delisted or moves to the pink sheets or OTC bulletin boards, the stock is deleted from the relevant indexes.

When acquisitions or mergers take place, the stock’s capitalization moves to the acquiring stock, hence, mergers have no effect on index total capitalization if the acquiring stock is part of the index. The only additions between reconstitution dates are as a result of spin-offs and initial public offerings.

Index Maintenance. Maintaining the Russell indexes includes monitoring and completing the adjustments for company additions and deletions, share changes, stock splits, stock dividends, and stock price adjustments due to restructuring and spin-offs and quarterly initial public offerings. In addition, significant share capital changes are made at month-end. The divisor is adjusted for all changes in company market value to leave the value of the investments unaffected. All divisor adjustments are made after the close of trading and after the calculation of the closing value of the Russell indexes.

Index Availability. The Russell indexes are calculated continuously and are available from major data vendors.

Russell 2500^TM Index

Number of Components: approximately 2,469

Index Description. The Russell 2500^TM Index measures the performance of the small- to mid-capitalization sector of the U.S. equity market. It is a float-adjusted capitalization-weighted index of equity securities issued by approximately 2500 of the smallest issuers in the Russell 3000^® Index. As of March 31, 2018, the Underlying Index represents approximately 17% of the total market capitalization of the Russell 3000^® Index.

Investment Restrictions

The Board has adopted as fundamental policies the following numbered investment restrictions, which cannot be changed without the approval of the holders of a majority of the Fund’s outstanding voting securities. A vote of a majority of the outstanding voting securities of the Fund is defined in the Investment Company Act as the lesser of (i) 67% or more of the voting securities present at a shareholder meeting, if the holders of more than 50% of the outstanding voting securities of the Fund are present or represented by proxy, or (ii) more than 50% of the outstanding voting securities of the Fund.The Fund has also adopted certain non-fundamental investment policies, including its investment objective. Non-fundamental investment policies may be changed by the Board without shareholder approval. Therefore, the Fund may change its investment objective and its Underlying Index without shareholder approval.

Fundamental Investment Policies

The Fund may not:

1.	Concentrate its investments in a particular industry, as that term is used in the Investment Company Act, except that the Fund will concentrate to approximately the same extent that its Underlying Index concentrates in the securities of a particular industry or group of industries.
2.	Borrow money, except as permitted under the Investment Company Act.
3.	Issue senior securities to the extent such issuance would violate the Investment Company Act.
4.	Purchase or hold real estate, except the Fund may purchase and hold securities or other instruments that are secured by, or linked to, real estate or interests therein, securities of REITs, mortgage-related securities and securities of issuers engaged in the real estate business, and the Fund may purchase and hold real estate as a result of the ownership of securities or other instruments.

Notations Regarding the Fund's Fundamental Investment Restrictions

The following notations are not considered to be part of the Fund's fundamental investment restrictions and are subject to change without shareholder approval.

With respect to the fundamental policy relating to borrowing money set forth in (2) above, the Investment Company Act permits the Fund to borrow money in amounts of up to one-third of the Fund’s total assets from banks for any purpose, and to borrow up to 5% of the Fund’s total assets from banks or other lenders for temporary purposes. (The Fund’s total assets include the amounts being borrowed.) To limit the risks attendant to borrowing, the Investment Company Act requires the Fund to maintain at all times an “asset coverage” of at least 300% of the amount of its borrowings. Asset coverage means the ratio that the value of the Fund's total assets (including amounts borrowed), minus liabilities other than borrowings, bears to the aggregate amount of all borrowings. Borrowing money to increase portfolio holdings is known as “leveraging.” Certain trading practices and investments, such as reverse repurchase agreements, may be considered to be borrowings or involve leverage and thus are subject to the Investment Company Act restrictions. In accordance with SEC staff guidance and interpretations, when the Fund engages in such transactions, the Fund instead of maintaining asset coverage of at least 300%, may segregate or earmark liquid assets, or enter into an offsetting position, in an amount at least equal to the Fund’s exposure, on a mark-to-market basis, to the transaction (as calculated pursuant to requirements of the SEC). The policy in (2) above will be interpreted to permit the Fund to engage in trading practices and investments that may be considered to be borrowing or to involve leverage to the extent permitted by the Investment Company Act and to permit the Fund to segregate or earmark liquid assets or enter into offsetting positions in accordance with the Investment Company Act. Short-term credits necessary for the settlement of securities transactions and arrangements with respect to securities lending will not be considered to be borrowings under the policy. Practices and investments that may involve leverage but are not considered to be borrowings are not subject to the policy.

currency and futures transactions and other derivative instruments (as applicable), as well as delays in the settlement of securities transactions, will not be considered loans.

Non-Fundamental Investment Policies

The Fund has adopted a non-fundamental policy not to make short sales of securities or maintain a short position, except to the extent permitted by the Fund's Prospectus and SAI, as amended from time to time, and applicable law.

The Fund has adopted a non-fundamental investment policy in accordance with Rule 35d-1 under the Investment Company Act to invest, under normal circumstances, at least 80% of the value of its net assets, plus the amount of any borrowings for investment purposes, in the securities of its Underlying Index or in depositary receipts representing component securities in its Underlying Index. The Fund also has adopted a policy to provide its shareholders with at least 60 days’ prior written notice of any change in such policy. If, subsequent to an investment, the 80% requirement is no longer met, the Fund’s future investments will be made in a manner that will bring the Fund into compliance with this policy.

The Fund has adopted a non-fundamental limitation such that, under normal market conditions, any borrowings by the Fund will not exceed 10% of the Fund’s net assets.

The Fund may not purchase securities of other investment companies, except to the extent permitted by the Investment Company Act. As a matter of policy, however, the Fund will not purchase shares of any registered open-end investment company or registered unit investment trust, in reliance on Section 12(d)(1)(F) or (G) (the “fund of funds” provisions) of the Investment Company Act, at any time the Fund has knowledge that its shares are purchased by another investment company investor in reliance on the provisions of subparagraph (G) of Section 12(d)(1); provided that such policy will only be in effect if the Fund ceases to invest its assets in reliance on Section 12(d)(1)(G) in the iShares Russell 2000 ETF (or a different underlying fund), as applicable.

In connection with its management of the Fund, BlackRock may have access to certain fundamental analysis and proprietary technical models developed by one or more Affiliates. BlackRock will not be under any obligation, however, to effect transactions on behalf of the Fund in accordance with such analysis and models. In addition, neither BlackRock nor any of the other Affiliates will have any obligation to make available any information regarding their proprietary activities or strategies, or the activities or strategies used for other accounts managed by them, for the benefit of the management of the Fund and it is not anticipated that BlackRock will have access to such information for the purpose of managing the Fund. The proprietary activities or portfolio strategies of BlackRock and the other Affiliates, or the activities or strategies used for accounts managed by them or other customer accounts could conflict with the transactions and strategies employed by BlackRock in managing the Fund.

for their clients, the underlying securities, currencies or instruments of which may be those in which the Fund invests or which may be based on the performance of the Fund. The Fund may, subject to applicable law, purchase investments that are the subject of an underwriting or other distribution by one or more Affiliates and may also enter into transactions with other clients of an Affiliate where such other clients have interests adverse to those of the Fund.

provide equal lending opportunities for all portfolios, independent of whether BlackRock indemnifies the portfolio. Equal opportunities for lending portfolios does not guarantee equal outcomes. Specifically, short and long-term outcomes for individual clients may vary due to asset mix, asset/liability spreads on different securities, and the overall limits imposed by the firm.

of clients, including the Fund. In certain circumstances, ECNs may offer volume discounts that will reduce the access fees typically paid by BlackRock. BlackRock will only utilize ECNs consistent with its obligation to seek to obtain best execution in client transactions.

Differentials in compensation may be related to the fact that BlackRock may pay a portion of its advisory fee to its Affiliate, or relate to compensation arrangements, including for portfolio management, brokerage transactions or account servicing. Any differential in compensation may create a financial incentive on the part of BlackRock or the other Affiliates and their personnel to recommend BlackRock over unaffiliated investment advisers or to effect transactions differently in one account over another.

circumstances in which BlackRock determined that it would be appropriate for the Fund to purchase and another client of BlackRock to sell, or the Fund to sell and another client of BlackRock to purchase, the same security or instrument on the same day. From time to time, the activities of the Fund may be restricted because of regulatory requirements applicable to BlackRock or the other Affiliates and/or BlackRock's internal policies designed to comply with, limit the applicability of, or otherwise relate to such requirements. A client not advised by BlackRock would not be subject to some of those considerations. There may be periods when BlackRock may not initiate or recommend certain types of transactions, or may otherwise restrict or limit their advice in certain securities or instruments issued by or related to companies for which an Affiliate is performing investment banking, market making, advisory or other services or has proprietary positions. For example, when an Affiliate is engaged in an underwriting or other distribution of securities of, or advisory services for, a company, the Fund may be prohibited from or limited in purchasing or selling securities of that company. In addition, when BlackRock provides advisory or risk management services for a company, BlackRock may be prohibited from or limited in purchasing or selling securities of that company on behalf of the Fund, particularly where such services result in BlackRock obtaining material non-public information about the company (e.g., in connection with participation in a creditors’ committee). Similar situations could arise if personnel of BlackRock or the other Affiliates serve as directors of companies the securities of which the Fund wishes to purchase or sell. However, if permitted by applicable law, and where consistent with BlackRock’s policies and procedures (including the necessary implementation of appropriate information barriers), the Fund may purchase securities or instruments that are issued by such companies, are the subject of an underwriting, distribution or advisory assignment by an Affiliate, or are the subject of an advisory or risk management assignment by BlackRock, or where personnel of BlackRock or the other Affiliates are directors or officers of the issuer.

If certain aggregate ownership thresholds are reached either through the actions of BlackRock or the Fund or as a result of third-party transactions, the ability of BlackRock, on behalf of clients (including the Fund), to purchase or dispose of investments, or exercise rights or undertake business transactions, may be restricted by regulation or otherwise impaired. As a result, BlackRock, on behalf of clients (including the Fund), may limit purchases, sell existing investments, or otherwise restrict, forgo or limit the exercise of rights (including transferring, outsourcing or limiting voting rights or forgoing the right to receive dividends) when BlackRock, in its sole discretion, deems it appropriate in light of potential regulatory or other restrictions on ownership or other consequences resulting from reaching investment thresholds.

BlackRock and the other Affiliates may not serve as Authorized Participants in the creation and redemption of iShares ETFs, but may serve as authorized participants of third-party ETFs.

The discussion below describes the Portfolio Managers' compensation as of March 31, 2018.

Portfolio Manager Compensation Overview

Base compensation. Generally, portfolio managers receive base compensation based on their position with the firm.

Other Compensation Benefits. In addition to base compensation and discretionary incentive compensation, portfolio managers may be eligible to receive or participate in one or more of the following:

Incentive Savings Plans — BlackRock, Inc. has created a variety of incentive savings plans in which BlackRock, Inc. employees are eligible to participate, including a 401(k) plan, the BlackRock Retirement Savings Plan (“RSP”), and the BlackRock Employee Stock Purchase Plan (“ESPP”). The employer contribution components of the RSP include a company match equal to 50% of the first 8% of eligible pay contributed to the plan capped at $5,000 per year, and a company retirement contribution equal to 3-5% of eligible compensation up to the U.S. Internal Revenue Service (the “IRS”) limit ($275,000 for 2018). The RSP offers a range of investment options, including registered investment companies and collective investment funds managed by the firm. BlackRock, Inc. contributions follow the investment direction set by participants for their own contributions or, absent participant investment direction, are invested into an index target date fund that corresponds to, or is closest to, the year in which the participant attains age 65. The ESPP allows for investment in BlackRock, Inc. common stock at a 5% discount on the fair market value of the stock on the purchase date. Annual participation in the ESPP is limited to the purchase of 1,000 shares of common stock or a dollar value of $25,000 based on its fair market value on the Purchase Date. Rachel Aguirre, Diane Hsiung, Jennifer Hsui, Alan Mason, Greg Savage and Amy Whitelaw are each eligible to participate in these plans.

As of March 31, 2018, the Portfolio Managers did not beneficially own shares of the Fund.

by the Trust for the Fund. State Street is authorized to appoint certain foreign custodians or foreign custody managers for Fund investments outside the U.S. Pursuant to the Service Module for Transfer Agency Services with the Trust, State Street acts as a transfer agent for the Fund’s authorized and issued shares of beneficial interest, and as dividend disbursing agent of the Trust. As compensation for these services, State Street receives certain out-of-pocket costs, transaction fees and asset-based fees which are accrued daily and paid monthly by BFA from its management fee.

The following table sets forth the administration, custodian and transfer agency expenses of the Fund paid by BFA to State Street for the fiscal years noted:

Fund Inception Date		Custody, Administration & Transfer Agency Expenses Paid During Fiscal Year Ended March 31, 2018		Custody, Administration & Transfer Agency Expenses Paid During Fiscal Year Ended March 31, 2017		Custody, Administration & Transfer Agency Expenses Paid During Fiscal Year Ended March 31, 2016
07/06/17		$7,429		N/A		N/A

The Fund retains a portion of the securities lending income and remits the remaining portion to BTC as compensation for its services as securities lending agent. Securities lending income is generally equal to the total of income earned from the reinvestment of cash collateral (and excludes collateral investment fees as defined below), and any fees or other payments to and from borrowers of securities. As securities lending agent, BTC bears all operational costs directly related to securities lending. The Fund is responsible for fees in connection with the investment of cash collateral received for securities on loan in a money market fund managed by BFA (the “collateral investment fees”); however, BTC has agreed to reduce the amount of securities lending income it receives in order to effectively limit the collateral investment fees the Fund bears to an annual rate of 0.04%. Such money market fund shares will not be subject to a sales load, redemption fee, distribution fee or service fee.

Pursuant to the Securities Lending Agency Agreement:

(i) Domestic equity funds, such as the Fund, retain 71.5% of securities lending income (which excludes collateral investment fees) and (ii) this amount can never be less than 65% of the sum of securities lending income plus collateral investment fees.

In addition, commencing the business day following the date that the aggregate securities lending income (which includes, for this purpose, collateral investment fees) earned across the Exchange-Traded Fund Complex (as defined under “Management—Trustees and Officers”) in a calendar year exceeds the aggregate securities lending income earned across the Exchange-Traded Fund Complex in calendar year 2013 (the Hurdle Date), each applicable domestic equity fund, pursuant to the securities lending agreement, will receive for the remainder of that calendar year securities lending income as follows:

(i) 75% of securities lending income (which excludes collateral investment fees) and (ii) this amount can never be less than 65% of the sum of securities lending income plus collateral investment fees.

The services provided to the Funds by BTC in the most recent fiscal year ended March 31, 2018 primarily included the following:

(1) selecting borrowers from an approved list of borrowers and executing a securities lending agreement as agent on behalf of the Funds with each such borrower;

(2) negotiating the terms of securities loans, including the amount of fees;

(3) directing the delivery of loaned securities;

(4) monitoring the daily value of the loaned securities and directing the payment of additional collateral or the return of excess collateral, as necessary;

(5) investing cash collateral received in connection with any loaned securities;

(6) monitoring distributions on loaned securities (for example, interest and dividend activity);

(8) terminating securities loans and arranging for the return of loaned securities to the Funds at loan termination.

The following tables show the dollar amounts of income and fees/compensation related to the securities lending activities of the Fund during its most recent fiscal year ended March 31, 2018 (the Fund’s inception date was July 6, 2017).

The Fund may participate in certain market maker incentive programs of a national securities exchange in which an affiliate of the Fund would pay a fee to the exchange used for the purpose of incentivizing one or more market makers in the securities of the Fund to enhance the liquidity and quality of the secondary market of securities of the Fund. The fee would then be credited by the exchange to one or more market makers that meet or exceed liquidity and market quality standards with respect to the securities of the Fund. Each market maker incentive program is subject to approval from the SEC. Any such fee payments made to an exchange will be made by an affiliate of the Fund solely for the benefit of the Fund and will not be paid from any Fund assets. Other funds managed by BFA may also participate in such programs.

Determination of Net Asset Value

Underlying Funds. Shares of underlying ETFs will be valued at their most recent closing price on an Exchange. Shares of underlying money market funds will be valued at their NAV.

All cash, receivables and current payables are carried on the Fund’s books at their face value.

Valuation Committee (or BlackRock’s Pricing Group) deems relevant at the time of the determination, and may be based on analytical values determined by BlackRock using proprietary or third-party valuation models.

Brokerage Transactions

In selecting brokers or dealers to execute portfolio transactions, BFA seeks to obtain the best price and most favorable execution for the Fund and may take into account a variety of factors including: (i) the size, nature and character of the security or instrument being traded and the markets in which it is purchased or sold; (ii) the desired timing of the transaction; (iii) BFA’s knowledge of the expected commission rates and spreads currently available; (iv) the activity existing and expected in the market for the particular security or instrument, including any anticipated execution difficulties; (v) the full range of brokerage services provided; (vi) the broker’s or dealer’s capital; (vii) the quality of research and research services provided; (viii) the reasonableness of the commission, dealer spread or its equivalent for the specific transaction; and (ix) BFA’s knowledge of any actual or apparent operational problems of a broker or dealer. Brokers may also be selected because of their ability to handle special or difficult executions, such as may be involved in large block trades, less liquid securities, or other circumstances.

services provided by that broker or dealer. This includes commissions paid on riskless principal transactions in securities under certain conditions.

allocate these investments fairly and equitably among client accounts over time, each portfolio manager or a member of his or her respective investment team will indicate to BFA’s trading desk their level of interest in a particular offering with respect to eligible clients’ accounts for which that team is responsible. IPOs of U.S. equity securities will be identified as eligible for particular client accounts that are managed by portfolio teams who have indicated interest in the offering based on market capitalization of the issuer of the security and the investment mandate of the client account and in the case of international equity securities, the country where the offering is taking place and the investment mandate of the client account. Generally, shares received during the IPO will be allocated among participating client accounts within each investment mandate on a pro rata basis. This pro rata allocation may result in the Fund receiving less of a particular security than if pro-rating had not occurred. All allocations of securities will be subject, where relevant, to share minimums established for accounts and compliance constraints. In situations where supply is too limited to be allocated among all accounts for which the investment is eligible, portfolio managers may rotate such investment opportunities among one or more accounts so long as the rotation system provides for fair access for all client accounts over time. Other allocation methodologies that are considered by BFA to be fair and equitable to clients may be used as well.

In certain instances, BFA may find it efficient for purposes of seeking to obtain best execution, to aggregate or “bunch” certain contemporaneous purchases or sale orders of its advisory accounts and advisory accounts of affiliates. In general, all contemporaneous trades for client accounts under management by the same portfolio manager or investment team will be bunched in a single order if the trader believes the bunched trade would provide each client with an opportunity to achieve a more favorable execution at a potentially lower execution cost. The costs associated with a bunched order will be shared pro rata among the clients in the bunched order. Generally, if an order for a particular portfolio manager or management team is filled at several different prices through multiple trades, all accounts participating in the order will receive the average price (except in the case of certain international markets where average pricing is not permitted). While in some cases this practice could have a detrimental effect upon the price or value of the security as far as the Fund is concerned, in other cases it could be beneficial to the Fund. Transactions effected by BFA or the other Affiliates on behalf of more than one of its clients during the same period may increase the demand for securities being purchased or the supply of securities being sold, causing an adverse effect on price. The trader will give the bunched order to the broker-dealer that the trader has identified as being able to provide the best execution of the order. Orders for purchase or sale of securities will be placed within a reasonable amount of time of the order receipt and bunched orders will be kept bunched only long enough to execute the order.

allocated among the Fund and the other accounts in a manner deemed equitable to all by BlackRock. In some cases, this procedure could have a detrimental effect on the price or volume of the security as far as the Fund is concerned. However, in other cases, it is possible that the ability to participate in volume transactions and to negotiate lower transaction costs will be beneficial to the Fund. BlackRock may deal, trade and invest for its own account in the types of securities in which the Fund may invest. BlackRock may, from time to time, effect trades on behalf of and for the account of the Fund with brokers or dealers that are affiliated with BFA, in conformity with the 1940 Act and SEC rules and regulations. Under these provisions, any commissions paid to affiliated brokers or dealers must be reasonable and fair compared to the commissions charged by other brokers or dealers in comparable transactions. The Fund will not deal with affiliates in principal transactions unless permitted by applicable SEC rules or regulations, or by SEC exemptive order.

Additional Information Concerning the Trust

Shareholders may make inquiries by writing to iShares Trust, c/o BlackRock Investments, LLC, 1 University Square Drive, Princeton, NJ 08540.

DTC as Securities Depository for Shares of the Fund. Shares of the Fund are represented by securities registered in the name of DTC or its nominee and deposited with, or on behalf of, DTC.

DTC was created in 1973 to enable electronic movement of securities between its participants (“DTC Participants”), and NSCC was established in 1976 to provide a single settlement system for securities clearing and to serve as central counterparty for securities trades among DTC Participants. In 1999, DTC and NSCC were consolidated within The Depository Trust & Clearing Corporation (“DTCC”) and became wholly-owned subsidiaries of DTCC. The common stock of DTCC is owned by the DTC Participants, but NYSE and FINRA, through subsidiaries, hold preferred shares in DTCC that provide them with the right to elect one member each to the DTCC board of directors. Access to the DTC system is available to entities, such as banks, brokers, dealers and trust companies, that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly (“Indirect Participants”).

Conveyance of all notices, statements and other communications to Beneficial Owners is effected as follows. Pursuant to the Depositary Agreement between the Trust and DTC, DTC is required to make available to the Trust upon request and for a fee to be charged to the Trust a listing of the shares of the Fund held by each DTC Participant. The Trust shall inquire of each such DTC Participant as to the number of Beneficial Owners holding shares, directly or indirectly, through such DTC Participant. The Trust shall provide each such DTC Participant with copies of such notice, statement or other communication, in such form, number and at such place as such DTC Participant may reasonably request, in order that such notice, statement or communication may be transmitted by such DTC Participant, directly or indirectly, to such Beneficial Owners. In addition, the Trust shall pay to each such DTC Participant a fair and reasonable amount as reimbursement for the expenses attendant to such transmittal, all subject to applicable statutory and regulatory requirements.

through such DTC Participants. DTC may decide to discontinue providing its service with respect to shares of the Trust at any time by giving reasonable notice to the Trust and discharging its responsibilities with respect thereto under applicable law. Under such circumstances, the Trust shall take action to find a replacement for DTC to perform its functions at a comparable cost.

Any Selling Shareholder and any other person participating in such distribution will be subject to applicable provisions of the 1934 Act and the rules and regulations thereunder.

Creation and Redemption of Creation Units

Shares Per Creation Unit		Approximate Value Per Creation Unit (U.S.$)
50,000		$2,168,500

Fund Deposit. The consideration for purchase of Creation Units of the Fund generally consists of Deposit Securities and the Cash Component computed as described below. Together, the Deposit Securities and the Cash Component constitute the “Fund Deposit,” which, when combined with the Fund's portfolio securities is designed to generate performance that has a collective investment profile similar to that of the Underlying Index. The Fund Deposit represents the minimum initial and subsequent investment amount for a Creation Unit of the Fund.

The Cash Component is an amount equal to the difference between the NAV of the shares (per Creation Unit) and the “Deposit Amount,” which is an amount equal to the market value of the Deposit Securities, and serves to compensate for any differences between the NAV per Creation Unit and the Deposit Amount. Payment of any stamp duty or other similar fees and expenses payable upon transfer of beneficial ownership of the Deposit Securities are the sole responsibility of the Authorized Participant purchasing the Creation Unit.

Cash Purchase Method. Although the Trust does not generally permit partial or full cash purchases of Creation Units of its funds, when partial or full cash purchases of Creation Units are available or specified for the Fund, they will be effected in essentially the same manner as in-kind purchases thereof. In the case of a partial or full cash purchase, the Authorized Participant must pay the cash equivalent of the Deposit Securities it would otherwise be required to provide through an in-kind purchase, plus the same Cash Component required to be paid by an in-kind purchaser.

Procedures for Creation of Creation Units. To be eligible to place orders with the Distributor and to create a Creation Unit of the Fund, an entity must be: (i) a “Participating Party,” i.e., a broker-dealer or other participant in the clearing process through the Continuous Net Settlement System of the NSCC (the “Clearing Process”), a clearing agency that is registered with the SEC, or (ii) a DTC Participant, and must have executed an agreement with the Distributor, with respect to creations and redemptions of Creation Units (“Authorized Participant Agreement”) (discussed below). A Participating Party or DTC Participant who has executed an Authorized Participant Agreement is referred to as an “Authorized Participant.” All shares of the Fund, however created, will be entered on the records of DTC in the name of Cede & Co. for the account of a DTC Participant.

result, purchase orders placed through an Authorized Participant may result in additional charges to such investor. The Trust does not expect to enter into an Authorized Participant Agreement with more than a small number of DTC Participants. A list of current Authorized Participants may be obtained from the Distributor. The Distributor has adopted guidelines regarding Authorized Participants’ transactions in Creation Units that are made available to all Authorized Participants. These guidelines set forth the processes and standards for Authorized Participants to transact with the Distributor and its agents in connection with creation and redemption transactions. In addition, the Distributor may be appointed as the proxy of the Authorized Participant and may be granted a power of attorney under its Authorized Participant Agreement.

The Authorized Participant is responsible for any and all expenses and costs incurred by the Fund, including any applicable cash amounts, in connection with any purchase order.

Timing of Submission of Purchase Orders. An Authorized Participant must submit an irrevocable order to purchase shares of the Fund generally before 4:00 p.m., Eastern time on any Business Day in order to receive that day's NAV. Creation Orders must be transmitted by an Authorized Participant in the form required by the Fund to the Distributor or its agent pursuant to procedures set forth in the Authorized Participant Agreement. Economic or market disruptions or changes, or telephone or other communication failure, may impede the ability to reach the Distributor or its agent or an Authorized Participant. The Fund's deadline specified above for the submission of purchase orders is referred to as the Fund's “Cutoff Time.” The Distributor or its agent, in their discretion, may permit the submission of such orders and requests by or through an Authorized Participant at any time (including on days on which the Listing Exchange is not open for business) via communication through the facilities of the Distributor's or its agent's proprietary website maintained for this purpose. Purchase orders and redemption requests, if accepted by the Trust, will be processed based on the NAV next determined after such acceptance in accordance with the Fund's Cutoff Times as provided in the Authorized Participant Agreement and disclosed in this SAI.

to the Fund; (v) acceptance of the Fund Deposit would, in the opinion of counsel, be unlawful; (vi) acceptance of the Fund Deposit would, in the discretion of the Fund or BFA, have an adverse effect on the Fund or the rights of beneficial owners; or (vii) circumstances outside the control of the Fund, the Distributor or its agent and BFA make it impracticable to process purchase orders. The Distributor or its agent shall notify a prospective purchaser of a Creation Unit and/or the Authorized Participant acting on behalf of such purchaser of its rejection of such order. The Fund, State Street, the sub-custodian and the Distributor or its agent are under no duty, however, to give notification of any defects or irregularities in the delivery of Fund Deposits nor shall any of them incur any liability for failure to give such notification.

In certain cases, Authorized Participants may create and redeem Creation Units on the same trade date and in these instances, the Fund reserves the right to settle these transactions on a net basis or require a representation from the Authorized Participants that the creation and redemption transactions are for separate beneficial owners. All questions as to the number of shares of each security in the Deposit Securities and the validity, form, eligibility and acceptance for deposit of any securities to be delivered shall be determined by the Fund and the Fund's determination shall be final and binding.

The following table sets forth the Fund's standard creation transaction fees and maximum additional charge (as described above):

Standard Creation Transaction Fee		Maximum Additional Charge*
$1,400		3.0%

*	As a percentage of the net asset value per Creation Unit.

The Trust may, in its sole discretion, substitute a “cash in lieu” amount to replace any Fund Security. The Trust also reserves the right to permit or require a “cash in lieu” amount in certain circumstances, including circumstances in which: (i) the delivery of a Fund Security to the Authorized Participant would be restricted under applicable securities or other local laws; or (ii) the delivery of a Fund Security to the Authorized Participant would result in the disposition of the Fund Security by the Authorized Participant due to restrictions under applicable securities or other local laws, or in certain other situations. The amount of cash paid out in such cases will be equivalent to the value of the substituted security listed as a Fund Security. In the event that the Fund Securities have a value greater than the NAV of the shares, a compensating cash payment equal to the difference is required to be made by or through an Authorized Participant by the redeeming shareholder. The Fund generally redeems Creation Units for Fund Securities, but the Fund reserves the right to utilize a cash option for redemption of Creation Units. The Fund may, in its sole discretion, provide such redeeming Authorized Participant a portfolio of securities that differs from the exact composition of the Fund Securities, but does not differ in NAV.

below) certain brokerage, tax, foreign exchange, execution, price movement and other costs and expenses related to the execution of trades resulting from such transaction (which may, in certain instances, be based on a good faith estimate of transaction costs). Authorized Participants will also bear the costs of transferring the Fund Securities from the Fund to their account on their order. Certain fees/costs associated with redemption transactions may be waived in certain circumstances. Investors who use the services of a broker or other financial intermediary to dispose of Fund shares may be charged a fee for such services.

The following table sets forth the Fund's standard redemption transaction fees and maximum additional charge (as described above):

Standard Redemption Transaction Fee		Maximum Additional Charge*
$1,400		2.0%

*	As a percentage of the net asset value per Creation Unit, inclusive of the standard redemption transaction fee.

A redemption request is considered to be in “proper form” if: (i) an Authorized Participant has transferred or caused to be transferred to the Fund's transfer agent the Creation Unit redeemed through the book-entry system of DTC so as to be effective by the Listing Exchange closing time on any Business Day on which the redemption request is submitted; (ii) a request in form satisfactory to the Fund is received by the Distributor or its agent from the Authorized Participant on behalf of itself or another redeeming investor within the time periods specified above; and (iii) all other procedures set forth in the Authorized Participant Agreement are properly followed.

Deliveries of redemption proceeds by the Fund are generally made within two Business Days (i.e., “T+2”). The Fund reserves the right to settle redemption transactions on a basis other than T+2 but by T+7, if necessary or appropriate under the circumstances and compliant with applicable law.

Taxes

several other requirements. Among such other requirements are the following: (i) at least 90% of the Fund’s annual gross income must be derived from dividends, interest, payments with respect to securities loans, gains from the sale or other disposition of stock or securities or non-U.S. currencies, other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies, and net income derived from interests in qualified publicly-traded partnerships (i.e., partnerships that are traded on an established securities market or tradable on a secondary market, other than partnerships that derive at least 90% of their income from interest, dividends, capital gains and other traditionally permitted RIC income); and (ii) at the close of each quarter of the Fund's taxable year, (a) at least 50% of the market value of the Fund’s total assets must be represented by cash and cash items, U.S. government securities, securities of other RICs and other securities, with such other securities limited for purposes of this calculation in respect of any one issuer to an amount not greater than 5% of the value of the Fund’s assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of the Fund's total assets may be invested in the securities (other than U.S. government securities or the securities of other RICs) of any one issuer, of two or more issuers of which 20% or more of the voting stock is held by the Fund and that are engaged in the same or similar trades or businesses or related trades or businesses, or the securities of one or more qualified publicly-traded partnerships.

Net Capital Loss Carryforwards. Net capital loss carryforwards may be applied against any net realized capital gains in each succeeding year, until they have been reduced to zero.

The Fund had tax basis net capital loss carryforwards as set forth in the table below as of March 31, 2018, the tax year-end for the Fund:

Investors considering buying shares just prior to a dividend or capital gain distribution should be aware that, although the price of shares purchased at that time may reflect the amount of the forthcoming distribution, such dividend or distribution may nevertheless be taxable to them. If the Fund is the holder of record of any security on the record date for any dividends payable with respect to such security, such dividends will be included in the Fund’s gross income not as of the date received but as of the later of (a) the date such security became ex-dividend with respect to such dividends (i.e., the date on which a buyer of the security would not be entitled to receive the declared, but unpaid, dividends); or (b) the date the Fund acquired such security. Accordingly, in order to satisfy its income distribution requirements, the Fund may be required to pay dividends based on anticipated earnings, and shareholders may receive dividends in an earlier year than would otherwise be the case.

that the Trust will exercise the right of rejection except in a case where the Trust determines that accepting the order could result in material adverse tax consequences to the Fund or its shareholders. The Trust also has the right to require information necessary to determine beneficial share ownership for purposes of the 80% determination.

that is 90 days before the date on which the stock becomes ex-dividend with respect to such dividend); (ii) the Fund or the shareholder is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to substantially similar or related property; or (iii) the shareholder elects to treat such dividend as investment income under Section 163(d)(4)(B) of the Internal Revenue Code. Dividends received by the Fund from a REIT or another RIC may be treated as qualified dividend income only to the extent the dividend distributions are attributable to qualified dividend income received by such REIT or other RIC. In addition, the Tax Act permits a direct REIT shareholder to claim a 20% “qualified business income” deduction for ordinary REIT dividends, but does not permit a RIC paying dividends attributable to such income to pass through this special treatment to its shareholders. Unless future legislation or regulations provide for a pass-through, investors in such a RIC will treat such distributions as ordinary dividend income, as under prior law, whereas a direct REIT investor would benefit from the special treatment. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income. Distributions by the Fund of its net short-term capital gains will be taxable as ordinary income.

through” its non-U.S. taxes may be treated as receiving additional dividend income subject to U.S. withholding tax. A non-U.S. tax credit may not exceed the investor’s U.S. federal income tax otherwise payable with respect to the investor’s non-U.S. source income. For this purpose, shareholders must treat as non-U.S. source gross income (i) their proportionate shares of non-U.S. taxes paid by the Fund and (ii) the portion of any dividend paid by the Fund that represents income derived from non-U.S. sources; the Fund’s gain from the sale of securities will generally be treated as U.S.-source income. Certain limitations will be imposed to the extent to which the non-U.S. tax credit may be claimed. If your Fund shares are loaned pursuant to securities lending arrangements, you may lose the ability to use any non-U.S. tax credits passed through by the Fund or to treat Fund dividends (paid while the shares are held by the borrower) as qualified dividends. Regarding a short sale with respect to shares of the Fund, substitute payments made to the lender of such shares may not be deductible under certain circumstances. Consult your financial intermediary or tax advisor.

The Underlying Fund, if invested in non-U.S. positions, may be subject to non-U.S. income taxes and non-U.S. financial transactions taxes. Each Underlying Fund that is permitted to do so may elect to “pass through” to its investors, including the Fund, the amount of non-U.S. income taxes paid by the Underlying Fund. The Fund will be eligible to elect to “pass through” such amounts to their stockholders and may do so, depending upon circumstances.

The Fund will make the appropriate tax elections, if possible, and take any additional steps that are necessary to mitigate the effects of these rules.

Other Taxes. Dividends, distributions and redemption proceeds may also be subject to additional state, local and non-U.S. taxes depending on each shareholder’s particular situation.

under a treaty. The withholding tax does not apply to regular dividends paid to a non-U.S. shareholder who provides an IRS Form W-8ECI, certifying that the dividends are effectively connected with the non-U.S. shareholder’s conduct of a trade or business within the U.S. Instead, the effectively connected dividends will be subject to regular U.S. income tax as if the non-U.S. shareholder were a U.S. shareholder. A non-U.S. corporation receiving effectively connected dividends may also be subject to additional “branch profits tax” imposed at a rate of 30% (or lower treaty rate). A non-U.S. shareholder who fails to provide an IRS Form W-8BEN, IRS Form W-8BEN-E or other applicable form may be subject to backup withholding at the appropriate rate.

Shares of the Fund held by a non-U.S. shareholder at death will be considered situated within the U.S. and subject to the U.S. estate tax.

INTRODUCTION TO BLACKROCK

PHILOSOPHY ON CORPORATE GOVERNANCE

CORPORATE GOVERNANCE, ENGAGEMENT AND VOTING

principles inform our voting decisions in relation to specific resolutions that may appear on the agenda of a shareholder meeting in the relevant market.

The six key themes are:

•	Boards and directors
•	Auditors and audit-related issues
•	Capital structure, mergers, asset sales and other special transactions
•	Remuneration and benefits
•	Social, ethical and environmental issues
•	General corporate governance matters

Boards and directors

We expect the board of directors to promote and protect shareholder interests by:

•	establishing an appropriate corporate governance structure;
•	supporting and overseeing management in setting strategy;
•	ensuring the integrity of financial statements;
•	making decisions regarding mergers, acquisitions and disposals;
•	establishing appropriate executive compensation structures; and
•	addressing business issues including social, ethical and environmental issues when they have the potential to materially impact company reputation and performance.

•	current employment at the company or a subsidiary;

Oversight

BlackRock’s Equity Policy Oversight Committee (EPOC) is informed of certain aspects of the work of the Global Corporate Governance Oversight Committee and the Corporate Governance Group.

Vote execution

A-7

Conflicts management

•	BlackRock has adopted a proxy voting oversight structure whereby the Corporate Governance Committees oversee the voting decisions and other activities of the Corporate Governance Group, and particularly its activities with respect to voting in the relevant region of each Corporate Governance Committee’s jurisdiction.
•	The Corporate Governance Committees have adopted Guidelines for each region, which set forth the firm’s views with respect to certain corporate governance and other issues that typically arise in the proxy voting context. The Corporate Governance Committees receive periodic reports regarding the specific votes cast by the Corporate Governance Group and regular updates on material process issues, procedural changes and other matters of concern to the Corporate Governance Committees.
•	BlackRock’s Global Corporate Governance Oversight Committee oversees the Global Head, the Corporate Governance Group and the Corporate Governance Committees. The Global Corporate Governance Oversight Committee conducts a review, at least annually, of the proxy voting process to ensure compliance with BlackRock’s risk policies and procedures.
•	BlackRock maintains a reporting structure that separates the Global Head and Corporate Governance Group from employees with sales responsibilities. In addition, BlackRock maintains procedures intended to ensure that all engagements with corporate issuers or dissident shareholders are managed consistently and without regard to BlackRock’s relationship with the issuer of the proxy or dissident shareholder. Within the normal course of business, the Global Head or Corporate Governance Group may engage directly with BlackRock clients, and with employees with sales responsibilities, in discussions regarding general corporate governance policy matters, and to otherwise ensure that proxy-related client service levels are met. The Global Head or Corporate Governance Group does not discuss any specific voting matter with a client prior to the disclosure of the vote decision to all applicable clients after the shareholder meeting has taken place, except if the client is acting in the capacity as issuer of the proxy or dissident shareholder and is engaging through the established procedures independent of the client relationship.
•	In certain instances, BlackRock may determine to engage an independent fiduciary to vote proxies as a further safeguard to avoid potential conflicts of interest or as otherwise required by applicable law. The independent fiduciary may either vote such proxies or provide BlackRock with instructions as to how to vote such proxies. In the latter case, BlackRock votes the proxy in accordance with the independent fiduciary’s determination. Use of an independent fiduciary has been

adopted for voting the proxies related to any company that is affiliated with BlackRock or any company that includes BlackRock employees on its board of directors.

Each Fund is managed by BlackRock Fund Advisors (“BFA”), an indirect wholly-owned subsidiary of BlackRock, Inc., and generally seeks to track the investment results of the specific benchmark index identified in the applicable Prospectus for that Fund (each, an “Underlying Index”). BlackRock International Limited, an affiliate of BFA, serves as the sub-adviser (the “Sub-Adviser”) to the iShares International Preferred Stock ETF.

generally, in exchange for portfolio securities and a Cash Amount (as defined in the Redemption of Creation Units section of this SAI). Creation Units typically are a specified number of shares, generally ranging from 50,000 to 150,000 shares or multiples thereof.

Exchange Listing and Trading

Shares of each Fund are listed for trading, and trade throughout the day, on the applicable Listing Exchange and in other secondary markets. Shares of certain Funds may also be listed on certain non-U.S. exchanges. There can be no assurance that the requirements of the Listing Exchange necessary to maintain the listing of shares of any Fund will continue to be met. The Listing Exchange may, but is not required to, remove the shares of a Fund from listing if, among other things: (i) following the initial 12-month period beginning upon the commencement of trading of Fund shares, there are fewer than 50 record and/or beneficial owners of shares of the Fund for 30 or more consecutive trading days, (ii) the value of the Underlying Index on which a Fund is based is no longer calculated or available, or (iii) any other event shall occur or condition shall exist that, in the opinion of the Listing Exchange, makes further dealings on the Listing Exchange inadvisable. The Listing Exchange will also remove shares of a Fund from listing and trading upon termination of the Fund or in the event a Fund does not comply with the continuous listing standards of the Listing Exchange, as described in the Fund’s Prospectus.

As in the case of other publicly-traded securities, when you buy or sell shares of a Fund through a broker, you may incur a brokerage commission determined by that broker, as well as other charges.

An IOPV has an equity securities component and a cash component. The equity securities values included in an IOPV are the values of the Deposit Securities for a Fund. While the IOPV reflects the current value of the Deposit Securities required to be deposited in connection with the purchase of a Creation Unit, it does not necessarily reflect the precise composition of the current portfolio of securities held by the Funds at a particular point in time because the current portfolio of the Funds may include securities that are not a part of the current Deposit Securities. Therefore, a Fund’s IOPV disseminated during the Listing Exchange trading hours should not be viewed as a real-time update of the Fund’s NAV, which is calculated only once a day.

Investment Strategies and Risks

Each Fund seeks to achieve its objective by investing primarily in securities issued by issuers that comprise its relevant Underlying Index and through transactions that provide substantially similar exposure to securities in the Underlying Index. Each Fund operates as an index fund and is not actively managed. Adverse performance of a security in a Fund’s portfolio will ordinarily not result in the elimination of the security from the Fund’s portfolio.

Each Fund engages in representative sampling, which is investing in a sample of securities selected by BFA to have a collective investment profile similar to that of the Fund's Underlying Index. Securities selected have aggregate investment characteristics (based on market capitalization and industry weightings), fundamental characteristics (such as return variability, earnings valuation and yield) and liquidity measures similar to those of the Underlying Index. A fund that uses representative sampling generally does not hold all of the securities that are in its underlying index.

Although the Funds do not seek leveraged returns, certain instruments used by the Funds may have a leveraging effect as described below.

Currency Transactions. A currency forward contract is an over-the-counter (“OTC”) obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days greater than two days from the date on which the contract is agreed upon by the parties, at a price set at the time of the contract. A non-deliverable currency forward is an OTC currency forward settled in a specified currency, on a specified date, based on the difference between the agreed-upon exchange rate and the market exchange rate. A currency futures contract is a contract that trades on an organized futures exchange involving an obligation to deliver or acquire a specified amount of a specific currency, at a specified price and at a specified future time. Currency futures contracts may be settled on a net cash payment basis rather than by the sale and delivery of the underlying currency. To the extent required by law, liquid assets committed to futures contracts will be maintained. Certain of the Funds do not expect to engage in currency transactions for the purpose of hedging against declines in the value of the Funds' assets that are denominated in a non-U.S. currency. A Fund may enter into non-U.S. currency forwards, non-deliverable currency forwards and non-U.S. currency futures transactions to facilitate local securities settlements or to protect against currency exposure in connection with its distributions to shareholders, but may not enter into such contracts for speculative purposes.

correlations incorrectly, foreign exchange transactions may not serve their intended purpose of improving the correlation of a Fund's return with the performance of its Underlying Index and may lower the Fund’s return. Each Fund could experience losses if the value of its currency forwards, options or futures positions were poorly correlated with its other investments or if it could not close out its positions because of an illiquid market or otherwise. In addition, a Fund could incur transaction costs, including trading commissions, in connection with certain non-U.S. currency transactions.

A fund classified as “diversified” under the 1940 Act may not purchase securities of an issuer (other than (i) obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities and (ii) securities of other investment companies) if, with respect to 75% of its total assets, (a) more than 5% of the fund’s total assets would be invested in securities of that issuer or (b) the fund would hold more than 10% of the outstanding voting securities of that issuer. With respect to the remaining 25% of its total assets, the fund may invest more than 5% of its assets in one issuer. Under the 1940 Act, a fund cannot change its classification from diversified to non-diversified without shareholder approval.

A “non-diversified” fund is a fund that is not limited by the 1940 Act with regard to the percentage of its assets that may be invested in the securities of a single issuer. The securities of a particular issuer (or securities of issuers in particular industries) may constitute a significant percentage of the underlying index of such a fund and, consequently, the fund’s investment portfolio. This may adversely affect a fund’s performance or subject the fund’s shares to greater price volatility than that experienced by more diversified investment companies.

Each Fund (whether diversified or non-diversified) intends to maintain the required level of diversification and otherwise conduct its operations so as to qualify as a regulated investment company (“RIC”) for purposes of the U.S. Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), and to relieve the Fund of any liability for U.S. federal income tax to the extent that its earnings are distributed to shareholders, provided that the Fund satisfies a minimum distribution requirement. Compliance with the diversification requirements of the Internal Revenue Code may limit the investment flexibility of the Funds and may make it less likely that the Funds will meet their respective investment objectives.

Futures, Options on Futures and Securities Options. Futures contracts, options on futures and securities options may be used by a Fund to simulate investment in its Underlying Index, to facilitate trading or to reduce transaction costs. Each Fund may enter into futures contracts and options on futures that are traded on a U.S. or non-U.S. futures exchange. Each Fund will not use futures, options on futures or securities options for speculative purposes. Each Fund intends to use futures and options on futures in accordance with Rule 4.5 of the Commodity Futures Trading Commission (the “CFTC”) promulgated under the Commodity Exchange Act (“CEA”). BFA, with respect to certain Funds, has claimed an exclusion from the definition of the term “commodity pool operator” in accordance with Rule 4.5 so that BFA, with respect to such Funds, is not subject to registration or regulation as a commodity pool operator under the CEA. See the Regulation Regarding Derivatives section of this SAI for more information.

price of the futures contract exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the futures contract. The potential for loss related to the purchase of an option on a futures contract is limited to the premium paid for the option plus transaction costs. Because the value of the option is fixed at the point of sale, there are no daily cash payments by the purchaser to reflect changes in the value of the underlying contract; however, the value of the option changes daily and that change would be reflected in the NAV of each Fund. The potential for loss related to writing call options is unlimited. The potential for loss related to writing put options is limited to the agreed-upon price per share, also known as the “strike price,” less the premium received from writing the put. Certain of the Funds may purchase and write put and call options on futures contracts that are traded on an exchange as a hedge against changes in value of their portfolio securities or in anticipation of the purchase of securities, and may enter into closing transactions with respect to such options to terminate existing positions. There is no guarantee that such closing transactions can be effected.

Securities options may be used by a Fund to obtain access to securities in its Underlying Index or to dispose of securities in its Underlying Index at favorable prices, to invest cash in a securities index that offers similar exposure to that provided by its Underlying Index or otherwise to achieve the Fund’s objective of tracking its Underlying Index. A call option gives a holder the right to purchase a specific security at a specified price (“exercise price”) within a specified period of time. A put option gives a holder the right to sell a specific security at an exercise price within a specified period of time. The initial purchaser of a call option pays the “writer” a premium, which is paid at the time of purchase and is retained by the writer whether or not such option is exercised. Each Fund may purchase put options to hedge its portfolio against the risk of a decline in the market value of securities held and may purchase call options to hedge against an increase in the price of securities it is committed to purchase. Each Fund may write put and call options along with a long position in options to increase its ability to hedge against a change in the market value of the securities it holds or is committed to purchase. Each Fund may purchase or sell securities options on a U.S. or non-U.S. securities exchange or in the OTC market through a transaction with a dealer. Options on a securities index are typically settled on a net basis based on the appreciation or depreciation of the index level over the strike price. Options on single name securities may be cash- or physically-settled, depending upon the market in which they are traded. Options may be structured so as to be exercisable only on certain dates or on a daily basis. Options may also be structured to have conditions to exercise (i.e., “Knock-in Events”) or conditions that trigger termination (i.e., “Knock-out Events”). Investments in futures contracts and other investments that contain leverage may require each Fund to maintain liquid assets in an amount equal to its delivery obligations under these contracts and other investments. Generally, each Fund maintains an amount of liquid assets equal to its obligations relative to the position involved, adjusted daily on a marked-to-market basis. With respect to futures contracts that are contractually required to “cash-settle,” each Fund maintains liquid assets in an amount at least equal to the Fund’s daily marked-to-market obligation (i.e., each Fund’s daily net liability, if any), rather than the contracts’ notional value (i.e., the value of the underlying asset). By maintaining assets equal to its net obligation under cash-settled futures contracts, each Fund may employ leverage to a greater extent than if the Fund were required to set aside assets equal to the futures contracts’ full notional value. Each Fund bases its asset maintenance policies on methods permitted by the SEC and its staff and may modify these policies in the future to comply with any changes in the guidance articulated from time to time by the SEC or its staff. Changes in SEC guidance regarding the use of derivatives by registered investment companies may adversely impact a Fund’s ability to invest in futures, options or other derivatives or make investments in such instruments more expensive.

Securities lending involves exposure to certain risks, including operational risk (i.e., the risk of losses resulting from problems in the settlement and accounting process), “gap” risk (i.e., the risk of a mismatch between the return on cash collateral reinvestments and the fees a Fund has agreed to pay a borrower), and credit, legal, counterparty and market risk. If a securities lending counterparty were to default, a Fund would be subject to the risk of a possible delay in receiving collateral or in recovering the loaned securities, or to a possible loss of rights in the collateral. In the event a borrower does not return a Fund’s securities as agreed, the Fund may experience losses if the proceeds received from liquidating the collateral do not at least equal the value of the loaned security at the time the collateral is liquidated, plus the transaction costs incurred in purchasing replacement securities. This event could trigger adverse tax consequences for a Fund. A Fund could lose money if its short-term investment of the collateral declines in value over the period of the loan. Substitute payments for dividends received by a Fund for securities loaned out by the Fund will not be considered qualified dividend income. BTC will take into account the tax effects on shareholders caused by this difference in connection with a Fund’s securities lending program. Substitute payments received on tax-exempt securities loaned out will not be tax-exempt income.

Non-U.S. Securities. Certain Funds purchase publicly-traded common stocks of non-U.S. issuers. To the extent a Fund invests in stocks of non-U.S. issuers, certain of the Fund's investments in such stocks may be in the form of American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) and European Depositary Receipts (“EDRs”) (collectively, “depositary receipts”). Depositary receipts are receipts, typically issued by a bank or trust issuer, which evidence ownership of underlying securities issued by a non-U.S. issuer. Depositary receipts may not necessarily be denominated in the same currency as their underlying securities. ADRs typically are issued by an American bank or trust company and evidence ownership of underlying securities issued by a foreign corporation. EDRs, which are sometimes referred to as Continental Depositary Receipts, are receipts issued in Europe, typically by foreign banks and trust companies, that evidence ownership of either foreign or domestic underlying securities. GDRs are depositary receipts structured like global debt issues to facilitate trading on an international basis. Generally, ADRs, issued in registered form, are designed for use in the U.S. securities markets, and EDRs, issued in bearer form, are designed for use in European securities markets. GDRs are tradable both in the U.S. and in Europe and are designed for use throughout the world.

The Funds will not invest in any unlisted depositary receipt or any depositary receipt that BFA deems illiquid at the time of purchase or for which pricing information is not readily available. In general, depositary receipts must be sponsored, but a Fund may invest in unsponsored depositary receipts under certain limited circumstances.

Depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted. In addition to investment risks associated with the underlying issuer, depositary receipts expose a Fund to additional risks associated with the non-uniform terms that apply to depositary receipt programs, credit exposure to the depository bank and to the sponsors and other parties with whom the depository bank establishes the programs, currency risk and liquidity risk. Unsponsored programs, which are not sanctioned by the issuer of the underlying common stock, generally expose investors to greater risks than sponsored programs and do not provide holders with many of the shareholder benefits that come from investing in a sponsored depositary receipts.

differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product (“GDP”), rate of inflation, capital reinvestment, resource self-sufficiency and balance of payment positions.

Regulation Regarding Derivatives. The CFTC subjects advisers to registered investment companies to regulation by the CFTC if a fund that is advised by the adviser either (i) invests, directly or indirectly, more than a prescribed level of its liquidation value in CFTC-regulated futures, options and swaps (“CFTC Derivatives”), or (ii) markets itself as providing investment exposure to such instruments. The CFTC also subjects advisers to registered investment companies to regulation by the CFTC if the registered investment company invests in one or more commodity pools. To the extent a Fund uses CFTC Derivatives, it intends to do so below such prescribed levels and intends not to market itself as a “commodity pool” or a vehicle for trading such instruments.

BFA has claimed an exclusion from the definition of the term “commodity pool operator” under the CEA pursuant to Rule 4.5 under the CEA with respect to the iShares Core S&P 500 ETF, iShares Global Clean Energy ETF, iShares Global Consumer Discretionary ETF, iShares Global Consumer Staples ETF, iShares Global Energy ETF, iShares Global Financials ETF, iShares Global Industrials ETF, iShares Global Infrastructure ETF, iShares Global Telecom ETF, iShares Global Utilities ETF, iShares International Preferred Stock ETF, iShares JPX-Nikkei 400 ETF, iShares Nasdaq Biotechnology ETF, iShares North American Natural Resources ETF, iShares North American Tech ETF, iShares North American Tech-Multimedia Networking ETF, iShares North American Tech-Software ETF, iShares PHLX Semiconductor ETF, iShares Russell 1000 Pure U.S. Revenue ETF, iShares Russell Mid-Cap Growth ETF, iShares Russell Top 200 ETF, iShares Russell Top 200 Growth ETF, iShares Russell Top 200 Value ETF, iShares S&P 100 ETF, iShares S&P 500 Growth ETF, iShares S&P 500 Value ETF, iShares S&P Mid-Cap 400 Growth ETF, iShares S&P Small-Cap 600 Growth ETF, iShares U.S. Aerospace & Defense ETF, iShares U.S. Broker-Dealers & Securities Exchanges ETF, iShares U.S. Healthcare Providers ETF, iShares U.S. Home Construction ETF, iShares U.S. Infrastructure ETF, iShares U.S. Insurance ETF, iShares U.S. Medical Devices ETF, iShares U.S. Oil & Gas Exploration & Production ETF, iShares U.S. Oil Equipment & Services ETF, iShares U.S. Pharmaceuticals ETF and iShares U.S. Telecommunications ETF. BFA is not, therefore, subject to registration or regulation as a “commodity pool operator” under the CEA with respect to the Funds.

The iShares Core S&P Mid-Cap ETF, iShares Core S&P Small-Cap ETF, iShares Core S&P Total U.S. Stock Market ETF, iShares Core S&P U.S. Growth ETF, iShares Core S&P U.S. Value ETF, iShares Europe ETF, iShares Global 100 ETF, iShares International Developed Property ETF, iShares Micro-Cap ETF, iShares Mortgage Real Estate ETF, iShares Residential Real Estate ETF, iShares Russell 1000 ETF, iShares Russell 1000 Growth ETF, iShares Russell 1000 Value ETF, iShares Russell 2000 ETF, iShares Russell 2000 Growth ETF, iShares Russell 2000 Value ETF, iShares Russell 3000 ETF, iShares Russell Mid-Cap ETF, iShares Russell Mid-Cap Value ETF, iShares S&P Mid-Cap 400 Value ETF, iShares S&P Small-Cap 600 Value ETF, iShares U.S. Preferred Stock ETF, iShares U.S. Real Estate ETF and iShares U.S. Regional Banks ETF (the “No-Action Letter Funds”) may also have investments in “underlying funds” (and such underlying funds themselves may invest in underlying funds) not advised by BFA (which for purposes of the no-action letter referenced below may include certain securitized vehicles, mortgage real estate investment trusts (“REITs”) and/or investment companies that may invest in CFTC Derivatives), and therefore may be viewed by the CFTC as commodity pools. BFA has no transparency into the holdings of these underlying funds because they are not advised by BFA. To address this issue of lack of transparency, the CFTC staff issued a no-action letter on November 29, 2012 permitting the adviser of a fund that invests in such underlying funds and that would otherwise have filed a claim of exclusion pursuant to CFTC Rule 4.5 to delay registration as a “commodity pool operator” until six months from the date on which the CFTC issues additional guidance on the treatment of CFTC Derivatives held by underlying funds. BFA, the adviser of the No-Action Letter Funds, has filed a claim with the CFTC for such Funds to rely on this no-action relief. Accordingly, BFA is not currently subject to registration or regulation as a “commodity pool operator” under the CEA in respect of such Funds.

As a result of regulatory requirements under the 1940 Act, each Fund is required to maintain an amount of liquid assets, accrued on a daily basis, having an aggregate value at least equal to the value of a Fund’s obligations under the applicable derivatives contract. To the extent that derivatives contracts are settled on a physical basis, a Fund will generally be required to maintain an amount of liquid assets equal to the notional value of the contract. On the other hand, in connection with

derivatives contracts that are performed on a net basis, a Fund will generally be required to maintain liquid assets, accrued daily, equal only to the accrued excess, if any, of a Fund’s obligations over those of its counterparty under the contract. Accordingly, reliance by a Fund on physically-settled derivatives contracts may adversely impact investors by requiring a Fund to set aside a greater amount of liquid assets than would generally be required if a Fund were relying on cash-settled derivatives contracts.

Reverse Repurchase Agreements. Reverse repurchase agreements involve the sale of securities with an agreement to repurchase the securities at an agreed-upon price, date and interest payment and have the characteristics of borrowing. Generally, the effect of such transactions is that a Fund can recover all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement, while in many cases the Fund is able to keep some of the interest income associated with those securities. Such transactions are advantageous only if a Fund has an opportunity to earn a rate of interest on the cash derived from these transactions that is greater than the interest cost of obtaining the same amount of cash. Opportunities to realize earnings from the use of the proceeds equal to or greater than the interest required to be paid may not always be available, and a Fund intends to use the reverse repurchase technique only when BFA believes it will be advantageous to the Fund. The use of reverse repurchase agreements may exaggerate any increase or decrease in the value of a Fund’s assets. A Fund’s exposure to reverse repurchase agreements will be covered by liquid assets having a value equal to or greater than the Fund’s obligations under such commitments. The use of reverse repurchase agreements is a form of leverage, and the proceeds obtained by a Fund through reverse repurchase agreements may be invested in additional securities.

issued by the SEC staff, fees and expenses of money market funds used for cash collateral received in connection with loans of securities are not treated as Acquired Fund Fees and Expenses, which reflect a Fund’s pro rata share of the fees and expenses incurred by investing in other investment companies (as disclosed in the Prospectus, as applicable).

Short-Term Instruments and Temporary Investments. Each Fund may invest in short-term instruments, including money market instruments, on an ongoing basis to provide liquidity or for other reasons. Money market instruments are generally short-term investments that may include, but are not limited to: (i) shares of money market funds (including those advised by BFA or otherwise affiliated with BFA); (ii) obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities (including government-sponsored enterprises); (iii) negotiable certificates of deposit (“CDs”), bankers’ acceptances, fixed-time deposits and other obligations of U.S. and non-U.S. banks (including non-U.S. branches) and similar institutions; (iv) commercial paper rated, at the date of purchase, “Prime-1” by Moody's^® Investors Service, Inc., “F-1” by Fitch Ratings, Inc., or “A-1” by Standard & Poor's^® Financial Services LLC, a subsidiary of S&P Global, Inc. (S&P Global Ratings), or if unrated, of comparable quality as determined by BFA; (v) non-convertible corporate debt securities (e.g., bonds and debentures) with remaining maturities at the date of purchase of not more than 397 days and that have been determined to present minimal credit risks, in accordance with the requirements set forth in Rule 2a-7 under the 1940 Act; (vi) repurchase agreements; and (vii) short-term U.S. dollar-denominated obligations of non-U.S. banks (including U.S. branches) that, in the opinion of BFA, are of comparable quality to obligations of U.S. banks that may be purchased by a Fund. Any of these instruments may be purchased on a current or forward-settled basis. Time deposits are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates. Bankers’ acceptances are time drafts drawn on commercial banks by borrowers, usually in connection with international transactions.

Swap Agreements. Swap agreements are contracts between parties in which one party agrees to make periodic payments to the other party based on the change in market value or level of a specified rate, index or asset. In return, the other party agrees to make periodic payments to the first party based on the return of a different specified rate, index or asset. Swap agreements will usually be performed on a net basis, with a Fund receiving or paying only the net amount of the two payments. The net amount of the excess, if any, of a Fund’s obligations over its entitlements with respect to each swap is accrued on a daily basis, and an amount of liquid assets having an aggregate value at least equal to the accrued excess will be maintained by the Fund.

Certain of the Funds may enter into currency, interest rate or index swaps, or, for the iShares S&P Small-Cap 600 Value ETF, total return swaps (some of which may be referred to as contracts for difference or “CFDs”). The use of currency, interest rate and index swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. These transactions generally do not involve the delivery of securities or other underlying assets.

Future Developments. The Board may, in the future, authorize each Fund to invest in securities contracts and investments, other than those listed in this SAI and in the applicable Prospectus, provided they are consistent with each Fund's investment objective and do not violate any of its investment restrictions or policies.

General Considerations and Risks

A discussion of some of the principal risks associated with an investment in a Fund is contained in the applicable Prospectus.

An investment in a Fund should be made with an understanding that the value of the Fund’s portfolio securities may fluctuate in accordance with changes in the financial condition of the issuers of the portfolio securities, the value of preferred or common stocks in general, and other factors that affect the market.

Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades and to the holding of securities, cash and other assets by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that may not be subject to independent evaluation. Local agents are held only to the standards of care of their local markets, and thus may be subject to limited or no government oversight. Communications between the U.S. and emerging market countries may be unreliable, increasing the risk of delayed settlements or losses of security certificates. In general, the less developed a country’s securities market is, the greater the likelihood of custody problems. Practices in relation to the settlement of securities transactions in emerging markets involve higher risks than those in developed markets, in part because of the use of brokers and counterparties that are often less well capitalized, and custody and registration of assets in some countries may be unreliable. The possibility of fraud, negligence or undue influence being exerted by the issuer or refusal to recognize ownership exists in some emerging markets, and, along with other factors, could result in ownership registration being lost. In addition, the laws of certain countries may put limits on a Fund’s ability to recover its assets if a foreign bank or depository or issuer of a security or an agent of any of the foregoing goes bankrupt. A Fund would absorb any loss resulting from such custody problems and may have no successful claim for compensation.

Dividend Risk. There is no guarantee that issuers of the stocks held by a Fund will declare dividends in the future or that, if declared, they will either remain at current levels or increase over time.

National Closed Market Trading Risk. To the extent that the underlying securities held by a Fund trade on foreign exchanges that are closed when the securities exchange on which a Fund’s shares trade is open, there are likely to be deviations between the current price of such an underlying security and the last quoted price for the underlying security (i.e., a Fund’s quote from the closed foreign market). These deviations may result in premiums or discounts to a Fund’s NAV that may be greater than those experienced by other ETFs.

Operational Risk. BFA and a Fund's other service providers may experience disruptions or operating errors such as processing errors or human errors, inadequate or failed internal or external processes, or systems or technology failures, that could negatively impact the Funds. While service providers are required to have appropriate operational risk management policies and procedures, their methods of operational risk management may differ from a Fund’s in the setting of priorities, the personnel and resources available or the effectiveness of relevant controls. BFA, through its monitoring and oversight of service providers, seeks to ensure that service providers take appropriate precautions to avoid and mitigate risks that could lead to disruptions and operating errors. However, it is not possible for BFA or the other Fund service providers to identify all of the operational risks that may affect a Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects.

Risk of Derivatives. A derivative is a financial contract, the value of which depends on, or is derived from, the value of an underlying asset, such as a security, a commodity (such as gold or silver), a currency or an index (a measure of value or rates, such as the S&P 500^® or the prime lending rate). A Fund may invest in futures contracts, securities options, CFDs (for the iShares S&P Small-Cap 600 Value ETF) and other derivatives. Compared to conventional securities, derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices and thus a Fund’s losses may be greater if it invests in derivatives than if it invests only in conventional securities. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations. Derivatives generally involve the incurrence of leverage. To address such leverage and to prevent a Fund from being deemed to have issued senior securities as a result of an investment in derivatives, such Fund will segregate liquid assets equal to its obligations under the derivatives throughout the life of the investment.

offset by gains, and the Fund will recognize losses on both the investment and the hedge. Hedges are sometimes subject to imperfect matching between the derivative and the underlying security, and there can be no assurance that a Fund's hedging transactions, which entail additional transaction costs, will be effective.

Risk of Equity Securities. An investment in a Fund should be made with an understanding of the risks inherent in an investment in equity securities, including the risk that the financial condition of issuers may become impaired or that the general condition of stock markets may deteriorate (either of which may cause a decrease in the value of the portfolio securities and thus in the value of shares of the Fund). Common stocks are susceptible to general stock market fluctuations and to increases and decreases in value as market confidence and perceptions of their issuers change. These investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies, inflation and interest rates, economic expansion or contraction, and global or regional political, economic or banking crises. Holders of common stocks incur more risks than holders of preferred stocks and debt obligations because common stockholders generally have rights to receive payments from stock issuers that are inferior to the rights of creditors, or holders of debt obligations or preferred stocks. Further, unlike debt securities, which typically have a stated principal amount payable at maturity (the value of which, however, is subject to market fluctuations prior to maturity), or preferred stocks, which typically have a liquidation preference and which may have stated optional or mandatory redemption provisions, common stocks have neither a fixed principal amount nor a maturity date. In addition, issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock price to decline.

Each of the iShares U.S. Preferred Stock ETF and the iShares International Preferred Stock ETF invests a significant portion of its assets in preferred stock, although all of the Funds may invest in preferred stock. A Fund that invests in preferred stock may be exposed to certain risks not typically encountered by investing in common stock. Many preferred stocks pay dividends at a fixed rate, therefore, a preferred stock’s market price may be sensitive to changes in interest rates in a manner similar to bonds — that is, as interest rates rise, the value of the preferred stock is likely to decline. Many preferred stocks also allow holders to convert the preferred stock into common stock of the issuer; the market price of such preferred stocks may be sensitive to changes in the value of the issuer’s common stock. In addition, the ability of an issuer of preferred stock to pay dividends may deteriorate or the issuer may default (i.e., fail to make scheduled dividend payments on the preferred stock or scheduled interest payments on other obligations of the issuer), which would negatively affect the value of any such holding. Dividend payments on a preferred stock typically must be declared by the issuer’s board of directors. An issuer’s board of directors is generally not under any obligation to pay a dividend (even if such dividends have accrued), and may suspend payment of dividends on preferred stock at any time. Preferred stock is also subject to market volatility and the price of preferred stock will fluctuate based on market demand. Preferred stock often has a call feature which allows the issuer to redeem the security at its discretion. Therefore, preferred stocks having a higher than average yield may be called by the issuer, which may cause a decrease in the yield of a Fund that invested in the preferred stock.

Although most of the securities in each Underlying Index are listed on a securities exchange, the principal trading market for some of the securities may be in the OTC market. The existence of a liquid trading market for certain securities may depend on whether dealers will make a market in such securities. There can be no assurance that a market will be made or maintained or that any such market will be or remain liquid. The price at which securities may be sold and the value of a Fund’s shares will be adversely affected if trading markets for the Fund’s portfolio securities are limited or absent, or if bid/ask spreads are wide.

Risk of Futures and Options on Futures Transactions. There are several risks accompanying the utilization of futures contracts and options on futures contracts. A position in futures contracts and options on futures contracts may be closed only on the exchange on which the contract was made (or a linked exchange). While each Fund plans to utilize futures contracts only if an active market exists for such contracts, there is no guarantee that a liquid market will exist for the contract at a specified time. Futures contracts, by definition, project price levels in the future and not current levels of valuation; therefore, market circumstances may result in a discrepancy between the price of the future and the movement in a Fund's Underlying Index. In the event of adverse price movements, a Fund would continue to be required to make daily cash payments to maintain its required margin. In such situations, if a Fund has insufficient cash, it may have to sell portfolio securities to meet daily margin requirements at a time when it may be disadvantageous to do so. In addition, a Fund may be required to deliver the instruments underlying the futures contracts it has sold.

a futures position may still be large as traditionally measured due to the low margin deposits required. In many cases, a relatively small price movement in a futures contract may result in immediate and substantial loss or gain to the investor relative to the size of a required margin deposit. The Funds, however, intend to utilize futures and options contracts in a manner designed to limit their risk exposure to levels comparable to a direct investment in the types of stocks in which they invest.

Utilization of futures and options on futures by a Fund involves the risk of imperfect or even negative correlation to its Underlying Index if the index underlying the futures contract differs from the Underlying Index. There is also the risk of loss of margin deposits in the event of bankruptcy of a broker with whom a Fund has an open position in the futures contract or option. The purchase of put or call options will be based upon predictions by BFA as to anticipated trends, which predictions could prove to be incorrect.

Because the futures market generally imposes less burdensome margin requirements than the securities market, an increased amount of participation by speculators in the futures market could result in price fluctuations. Certain financial futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. The daily limit establishes the maximum amount by which the price of a futures contract may vary either up or down from the previous day’s settlement price at the end of a trading session. Once the daily limit has been reached in a particular type of contract, no trades may be made on that day at a price beyond that limit. It is possible that futures contract prices could move to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and subjecting each Fund to substantial losses. In the event of adverse price movements, each Fund would be required to make daily cash payments of variation margin.

Risk of Investing in Non-U.S. Equity Securities. An investment in any of the Funds that invest, directly or indirectly, in non-U.S. equity securities involves risks similar to those of investing in portfolios of equity securities traded on non-U.S. exchanges. These risks include market fluctuations caused by such factors as economic and political developments in those foreign countries, changes in interest rates and perceived trends in stock prices. Investing in securities issued by issuers domiciled in countries other than the domicile of the investor and denominated in currencies other than an investor’s local currency entails certain considerations and risks not typically encountered by the investor in making investments in its home country and in that country’s currency. These considerations include favorable or unfavorable changes in interest rates, currency exchange rates, exchange control regulations and the costs that may be incurred in connection with conversions between various currencies. Investing in any of these Funds also involves certain risks and considerations not typically associated with investing in a fund whose portfolio contains exclusively securities of U.S. issuers. These risks include generally less liquid and less efficient securities markets; generally greater price volatility; less publicly available information about issuers; the imposition of withholding or other taxes; the imposition of restrictions on the expatriation of funds or other assets of the Funds; higher transaction and custody costs; delays and risks attendant in settlement procedures; difficulties in enforcing contractual obligations; lower liquidity and significantly smaller market capitalization; different accounting and disclosure standards; lower levels of regulation of the securities markets; more substantial government interference with the economy and businesses; higher rates of inflation; greater social, economic, and political uncertainty; the risk of nationalization or expropriation of assets; and the risk of war.

Risk of Investing in Micro-Capitalization Companies. Certain of the Funds may invest in securities of micro-capitalization companies. Micro-capitalization companies may have limited operational histories and new or unproven product lines, or may have product lines that are still in development. These companies may be more vulnerable than larger companies to key personnel losses due to reliance on a smaller number of management personnel. Micro-capitalization companies may have limited financial resources and little or no access to additional credit and therefore may be more susceptible to market down turns or rising credit costs than larger, more established companies. Share prices of micro-capitalization companies may be more volatile than those of larger companies and therefore a Fund’s share price may be more volatile than the share prices of funds that invest a larger percentage of assets in shares issued by small-, mid-, or large-capitalization companies. The shares of micro-capitalization companies may be thinly traded and may be at risk for delisting from a securities exchange, making it difficult for a Fund to buy and sell shares of a particular micro-capitalization company. In addition, there may be less public information available about these companies.

Risk of Investing in Mid-Capitalization Companies. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies, and, therefore, a Fund’s share price may be more volatile than that of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it more difficult for the Funds to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments.

Risk of Investing in Small-Capitalization Companies. Stock prices of small-capitalization companies may be more volatile than those of larger companies, and, therefore, a Fund's share price may be more volatile than that of funds that invest a larger percentage of their assets in stocks issued by large-capitalization or mid-capitalization companies. Stock prices of small-capitalization companies are generally more vulnerable than those of large-capitalization or mid-capitalization companies to adverse business and economic developments. The stocks of small-capitalization companies may be thinly traded, making it difficult for the Funds to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making them more vulnerable to loss of personnel. Small-capitalization companies also normally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments concerning their products.

Risk of Non-U.S. Preferred Stock. A Fund that invests in preferred stock may be exposed to certain risks not typically encountered by investing in common stock. Many preferred stocks pay dividends at a fixed rate, therefore, a preferred stock’s market price may be sensitive to changes in interest rates in a manner similar to bonds — that is, as interest rates rise, the value of the preferred stock is likely to decline. Many preferred stocks also allow holders to convert the preferred stock into common stock of the issuer; the market price of such preferred stocks can be sensitive to changes in the value of the issuer’s common stock. In addition, the ability of an issuer of preferred stock to pay dividends may deteriorate or the issuer may default (i.e., fail to make scheduled dividend payments on the preferred stock or scheduled interest payments on other obligations of the issuer), which would negatively affect the value of any such holding. Dividend payments on a preferred stock typically must be declared by the issuer’s board of directors. An issuer’s board of directors is generally not under any obligation to pay a dividend (even if such dividends have accrued), and may suspend payment of dividends on preferred stock at any time. Preferred stock is also subject to market volatility and the price of preferred stock will fluctuate based on market demand. Preferred stock often has a call feature which allows the issuer to redeem the security at its discretion. Therefore, preferred stocks having a higher than average yield may be called by the issuer, which may cause a decrease in the yield of a fund that invested in the preferred stock. Also, non U.S. preferred stock may have different rights or privileges than those commonly associated with U.S. preferred stock. In addition to the risks listed above, investors in non U.S. preferred stock may experience difficulty or uncertainty in determining and enforcing their rights related to preferred stock.

Risk of Swap Agreements. The risk of loss with respect to swaps is generally limited to the net amount of payments that a Fund is contractually obligated to make. Swap agreements are subject to the risk that the swap counterparty will default on its obligations to pay a Fund and the risk that a Fund will not be able to meet its obligations to pay the other party to the agreement. If such a default occurs, the parties will have contractual remedies pursuant to the agreements related to the transaction. However, such remedies may be subject to bankruptcy and insolvency laws, which could affect such Fund’s rights as a creditor (e.g., a Fund may not receive the net amount of payments that it is contractually entitled to receive). Swap agreements may also involve the risk that there is an imperfect correlation between the return on a Fund's obligation to its counterparty and the return on the referenced asset. In addition, swap agreements are subject to market and liquidity risk, leverage risk and hedging risk.

A Fund is required to post and collect variation margin (comprised of specified liquid securities subject to haircuts) in connection with trading of OTC swaps. Implementation of regulations requiring posting of initial margin is being phased in through 2020. These requirements may raise the costs for a Fund’s investment in swaps.

Certain Asian countries have democracies with relatively short histories, which may increase the risk of political instability. These countries have faced political and military unrest, and further unrest could present a risk to their local economies and securities markets. Indonesia and the Philippines have each experienced violence and terrorism, which has negatively impacted their economies. North Korea and South Korea each have substantial military capabilities, and historical tensions between the two countries present the risk of war. Escalated tensions involving the two countries and any outbreak of hostilities between the two countries, or even the threat of an outbreak of hostilities, could have a severe adverse effect on the entire Asian region. Political, religious, and border disputes persist in India. India has recently experienced and may continue to experience civil unrest and hostilities with certain of its neighboring countries. Increased political and social unrest in these geographic areas could adversely affect the performance of investments in this region.

Risk of Investing in Australasia. The economies of Australasia, which include Australia and New Zealand, are dependent on exports from the agricultural and mining sectors. This makes Australasian economies susceptible to fluctuations in the commodity markets. Australasian economies are also increasingly dependent on their growing service industries. Australia and New Zealand are located in a part of the world that has historically been prone to natural disasters, such as drought and flooding. Any such event in the future could have a significant adverse impact on the economies of Australia and New Zealand and affect the value of securities held by a Fund. The economies of Australia and New Zealand are dependent on trading with certain key trading partners, including Asia, Europe and the U.S. The Australia–U.S. Free Trade Agreement has significantly expanded the trading relationship between the U.S. and Australia. Economic events in the U.S., Asia, or in other key trading countries can have a significant economic effect on the Australian economy. The economies of Australia and New Zealand are heavily dependent on the mining sector. Passage of new regulations limiting foreign ownership of companies in the mining sector or imposition of new taxes on profits of mining companies may dissuade foreign investment, and as a result, have a negative impact on companies to which a Fund has exposure.

Risk of Investing in Canada. The U.S. is Canada’s largest trading and investment partner, and the Canadian economy is significantly affected by developments in the U.S. economy. Since the implementation of the North American Free Trade Agreement (“NAFTA”) in 1994 among Canada, the U.S. and Mexico, total two-way merchandise trade between the U.S. and Canada has more than doubled. Any downturn in U.S. or Mexican economic activity is likely to have an adverse impact on the Canadian economy. The U.S. government has indicated that it may drop out of NAFTA. If this were to occur, it could have a material adverse impact on the Canadian economy, which could impact the value of the securities whose value is linked to the Canadian economy. The U.S. has also recently imposed tariffs on Canadian aluminum and steel and threatened that it may impose additional tariffs. These actions may have an adverse impact on Canadian securities. The Canadian economy is also dependent upon external trade with other key trading partners, specifically China and the United Kingdom (the “U.K.”). As a result, Canada is dependent on the economies of these other countries. In addition, Canada is a large supplier of natural resources (e.g., oil, natural gas and agricultural products). As a result, the Canadian economy is sensitive to fluctuations in certain commodity prices.

Risk of Investing in Central and South America. The economies of certain Central and South American countries have experienced high interest rates, economic volatility, inflation, currency devaluations, government defaults, high unemployment rates and political instability which can adversely affect issuers in these countries. In addition, commodities (such as oil, gas and minerals) represent a significant percentage of exports for the regions and many economies in these regions are particularly sensitive to fluctuations in commodity prices. Adverse economic events in one country may have a significant adverse effect on other countries of these regions.

The governments of certain countries in Central and South America may exercise substantial influence over many aspects of the private sector and may own or control many companies. Future government actions could have a significant effect on the economic conditions in such countries, which could have a negative impact on the securities in which a Fund invests. Diplomatic developments may also adversely affect investments in certain countries in Central and South America. Some countries in Central and South America may be affected by public corruption and crime, including organized crime.

Certain countries in Central and South America may be heavily dependent upon international trade and, consequently, have been and may continue to be negatively affected by trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which they trade. These countries also have been and may continue to be adversely affected by economic conditions in the countries with which they trade. In addition, certain issuers located in countries in Central and South America in which a Fund invests may have dealings with countries subject to sanctions and/or embargoes imposed by the U.S. government and the United Nations and/or countries identified by the U.S. government as state sponsors of terrorism. An issuer may sustain damage to its reputation if it is identified as an issuer that has dealings with such countries. A Fund may be adversely affected if it invests in such issuers.

Risk of Investing in China. Investments in securities of companies domiciled in China involve a high degree of risk and special considerations not typically associated with investing in the U.S. securities markets. Such heightened risks include, among others, an authoritarian government, popular unrest associated with demands for improved political, economic and social conditions, the impact of regional conflict on the economy and hostile relations with neighboring countries.

Military conflicts, either in response to internal social unrest or conflicts with other countries, could disrupt economic development. The Chinese economy is vulnerable to the long-running disagreements with Hong Kong related to integration and religious and nationalist disputes with Tibet and the Xinjiang region. China has a complex territorial dispute regarding the sovereignty of Taiwan that has included threats of invasion; Taiwan-based companies and individuals are significant investors in China. Military conflict between China and Taiwan may adversely affect securities of Chinese issuers. In addition, China has strained international relations with Japan, India, Russia and other neighbors due to territorial disputes, historical animosities and other defense concerns. China could be affected by military events on the Korean peninsula or internal instability within North Korea. These situations may cause uncertainty in the Chinese market and may adversely affect performance of the Chinese economy.

The Chinese government has implemented significant economic reforms in order to liberalize trade policy, promote foreign investment in the economy, reduce government control of the economy and develop market mechanisms. However, there can be no assurance that these reforms will continue or that they will be effective. Despite reforms and privatizations of companies in certain sectors, the Chinese government still exercises substantial influence over many aspects of the private sector and may own or control many companies. The Chinese government continues to maintain a major role in economic policy making and investing in China involves risk of loss due to expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested. In addition, there is less regulation and monitoring of Chinese securities markets and the activities of investors, brokers and other participants than in the U.S. Accordingly, issuers of securities in China are not subject to the same degree of regulation as are U.S. issuers with respect to such matters as insider trading rules, tender offer regulation, stockholder proxy requirements and the requirements mandating timely and accurate disclosure of information. Stock markets in China are in the process of change and further development. This may lead to trading volatility, difficulty in the settlement and recording of transactions and difficulty in interpreting and applying the relevant regulation.

and services, institution of tariffs or other trade barriers or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the securities of Chinese issuers.

The tax laws and regulations in the PRC are subject to change, including the issuance of authoritative guidance or enforcement, possibly with retroactive effect. The interpretation, applicability and enforcement of such laws by PRC tax authorities are not as consistent and transparent as those of more developed nations, and may vary over time and from region to region. The application and enforcement of PRC tax rules could have a significant adverse effect on a Fund and its investors, particularly in relation to capital gains withholding tax imposed upon non-residents.

Risk of Investing in the Chinese Equity Markets. The iShares Global Clean Energy ETF may invest in H-shares (securities of companies incorporated in the PRC that are denominated in Hong Kong dollars and listed on the Stock Exchange of Hong Kong (“SEHK”)) and/or B-shares (securities of companies incorporated in the PRC that are denominated in U.S. dollars (in the case of the Shanghai Stock Exchange (“SSE”)) or Hong Kong dollars (in the case of the Shenzhen Stock Exchange (“SZSE”)) and listed on the SSE and the SZSE). The iShares Global Clean Energy ETF may also invest in certain Hong Kong listed securities known as Red-Chips (securities issued by companies incorporated in certain foreign jurisdictions, which are controlled, directly or indirectly, by entities owned by the national government or local governments in the PRC and derive substantial revenues or allocate substantial assets in the PRC) and P-Chips (securities issued by companies incorporated in certain foreign jurisdictions, which are controlled, directly or indirectly, by individuals in the PRC and derive substantial revenues or allocate substantial assets in the PRC).

Securities listed on the SSE or the SZSE are divided into two classes: A-shares (securities of companies incorporated in the PRC that are denominated in renminbi and listed on the SSE and SZSE), which are mostly limited to domestic investors, and B-shares, which are allocated for both international and domestic investors. The A-shares market is generally subject to greater government restrictions, including trading suspensions, which may lead to increased liquidity risks. The B-shares market is generally smaller, less liquid and has a smaller issuer base than the A-shares market, which may lead to significant price volatility. B-shares, H-shares, P-Chips or Red-Chips of issuers that also issue A-shares may trade at significant discounts to their A-shares counterparts. The issuance of B-shares and H-shares by Chinese companies and the ability to obtain a “back-door listing” through Red-Chips or P-Chips is still regarded by the Chinese authorities as an experiment in economic reform. “Back-door listing” is a means by which a mainland Chinese company issues Red-Chips or P-Chips to obtain quick access to international listing and international capital. All of these share mechanisms are relatively untested and subject to political and economic policy in China. Market developments, adverse investor perceptions, regulatory and government intervention (including the possibility of widespread trading suspensions implemented by regulators) and other factors may make it difficult to acquire, dispose of or value Chinese securities, which would lead to adverse effects to the Fund.

Risk of Investing in Denmark. Investments in Danish issuers subject the Fund to legal, regulatory, political, currency, security, and economic risks specific to Denmark. Denmark’s industrialized market economy depends on imported raw materials and foreign trade. As a result, Denmark is dependent on trading relationships with certain key trading partners, including other European Union (“EU”) countries and the United States. Denmark’s economy has also been characterized by slow growth and is facing demographic challenges that could lead to labor supply shortages in the near future. Secessionist movements, such as the Catalan movement in Spain or Scotland, may have an adverse effect on the Danish economy.

Risk of Investing in Developed Countries. Many countries with developed markets have recently experienced significant economic pressures. These countries generally tend to rely on the services sectors (e.g., the financial services sector) as the primary source of economic growth and may be susceptible to the risks of individual service sectors. For example, companies in the financial services sector are subject to governmental regulation and, recently, government intervention, which may adversely affect the scope of their activities, the prices they can charge and amount of capital they must maintain. Recent dislocations in the financial sector and perceived or actual governmental influence over certain financial companies may lead to credit rating downgrades and, as a result, impact, among other things, revenue growth for such companies. If financial companies experience a prolonged decline in revenue growth, certain developed countries that rely heavily on financial companies as an economic driver may experience a correlative slowdown. Recently, new concerns have emerged with respect to the economic health of certain developed countries. These concerns primarily stem from heavy indebtedness of many developed countries and their perceived inability to continue to service high debt loads without simultaneously implementing stringent austerity measures. Such concerns have led to tremendous downward pressure on the economies of these countries. As a result, it is possible that interest rates on debt of certain developed countries may rise to levels that make it difficult for such countries to service such debt. Spending on health care and retirement pensions in most developed countries has risen dramatically over the last few years. Medical innovation, extended life expectancy and higher public

expectations are likely to continue the increase in health care and pension costs. Any increase in health care and pension costs will likely have a negative impact on the economic growth of many developed countries. Certain developed countries rely on imports of certain key items, such as crude oil, natural gas, and other commodities. As a result, an increase in demand for, or price fluctuations of, certain commodities may negatively affect developed country economies. Developed market countries generally are dependent on the economies of certain key trading partners. Changes in any one economy may cause an adverse impact on several developed countries. In addition, heavy regulation of, among others, labor and product markets may have an adverse effect on certain issuers. Such regulations may negatively affect economic growth or cause prolonged periods of recession. Such risks, among others, may adversely affect the value of a Fund’s investments.

Risk of Investing in Emerging Markets. Investments in emerging market countries may be subject to greater risks than investments in developed countries. These risks include: (i) less social, political, and economic stability; (ii) greater illiquidity and price volatility due to smaller or limited local capital markets for such securities, or low or non-existent trading volumes; (iii) custodians, clearinghouses, foreign exchanges and broker-dealers may be subject to less scrutiny and regulation by local authorities; (iv) local governments may decide to seize or confiscate securities held by foreign investors and/or local governments may decide to suspend or limit an issuer's ability to make dividend or interest payments; (v) local governments may limit or entirely restrict repatriation of invested capital, profits, and dividends; (vi) capital gains may be subject to local taxation, including on a retroactive basis; (vii) issuers facing restrictions on dollar or euro payments imposed by local governments may attempt to make dividend or interest payments to foreign investors in the local currency; (viii) investors may experience difficulty in enforcing legal claims related to the securities and/or local judges may favor the interests of the issuer over those of foreign investors; (ix) bankruptcy judgments may only be permitted to be paid in the local currency; (x) limited public information regarding the issuer may result in greater difficulty in determining market valuations of the securities; and (xi) lack of financial reporting on a regular basis, substandard disclosure and differences in accounting standards may make it difficult to ascertain the financial health of an issuer.

Emerging market securities markets are typically marked by a high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries, as well as a high concentration of ownership of such securities by a limited number of investors. In addition, brokerage and other costs associated with transactions in emerging market securities can be higher, sometimes significantly, than similar costs incurred in securities markets in developed countries. Although some emerging markets have become more established and tend to issue securities of higher credit quality, the markets for securities in other emerging market countries are in the earliest stages of their development, and these countries issue securities across the credit spectrum. Even the markets for relatively widely traded securities in emerging market countries may not be able to absorb, without price disruptions, a significant increase in trading volume or trades of a size customarily undertaken by institutional investors in the securities markets of developed countries. The limited size of many of these securities markets can cause prices to be erratic for reasons apart from factors that affect the soundness and competitiveness of the securities issuers. For example, prices may be unduly influenced by traders who control large positions in these markets. Additionally, market making and arbitrage activities are generally less extensive in such markets, which may contribute to increased volatility and reduced liquidity of such markets. The limited liquidity of emerging market country securities may also affect a Fund's ability to accurately value its portfolio securities or to acquire or dispose of securities at the price and time it wishes to do so or in order to meet redemption requests.

Many emerging market countries suffer from uncertainty and corruption in their legal frameworks. Legislation may be difficult to interpret and laws may be too new to provide any precedential value. Laws regarding foreign investment and private property may be weak or non-existent. Sudden changes in governments may result in policies which are less favorable to investors such as policies designed to expropriate or nationalize “sovereign” assets. Certain emerging market countries in the past have expropriated large amounts of private property, in many cases with little or no compensation, and there can be no assurance that such expropriation will not occur in the future.

Investment in the securities markets of certain emerging market countries is restricted or controlled to varying degrees. These restrictions may limit a Fund's investment in certain emerging market countries and may increase the expenses of the Fund. Certain emerging market countries require governmental approval prior to investments by foreign persons or limit investment by foreign persons to only a specified percentage of an issuer's outstanding securities or a specific class of securities which may have less advantageous terms (including price) than securities of the company available for purchase by nationals.

labor strikes, civil wars, and religious oppression. Economic instability in emerging market countries may take the form of: (i) high interest rates; (ii) high levels of inflation, including hyperinflation; (iii) high levels of unemployment or underemployment; (iv) changes in government economic and tax policies, including confiscatory taxation; and (v) imposition of trade barriers.

A Fund's income and, in some cases, capital gains from foreign securities will be subject to applicable taxation in certain of the emerging market countries in which it invests, and treaties between the U.S. and such countries may not be available in some cases to reduce the otherwise applicable tax rates.

Emerging markets also have different clearance and settlement procedures, and in certain of these emerging markets there have been times when settlements have been unable to keep pace with the volume of securities transactions, making it difficult to conduct such transactions.

In the past, certain governments in emerging market countries have become overly reliant on the international capital markets and other forms of foreign credit to finance large public spending programs, which in the past have caused huge budget deficits. Often, interest payments have become too overwhelming for a government to meet, representing a large percentage of total GDP. These foreign obligations have become the subject of political debate and served as fuel for political parties of the opposition, which pressure the government not to make payments to foreign creditors, but instead to use these funds for, among other things, social programs. Either due to an inability to pay or submission to political pressure, foreign governments have been forced to seek a restructuring of their loan and/or bond obligations, have declared a temporary suspension of interest payments or have defaulted. These events have adversely affected the values of securities issued by foreign governments and corporations domiciled in those countries and have negatively affected not only their cost of borrowing, but their ability to borrow in the future as well.

Risk of Investing in Europe. Investing in European countries may expose a Fund to the economic and political risks associated with Europe in general and the specific European countries in which it invests. The economies and markets of European countries are often closely connected and interdependent, and events in one European country can have an adverse impact on other European countries. A Fund makes investments in securities of issuers that are domiciled in, or have significant operations in, member states of the Economic and Monetary Union of the EU, which requires member states to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Changes in imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro (the common currency of certain EU countries), the default or threat of default by an EU member state on its sovereign debt, and/or an economic recession in an EU member state may have a significant adverse effect on the economies of EU member states and their trading partners. Although certain European countries do not use the euro, many of these countries are obliged to meet the criteria for joining the euro zone. Consequently, these countries must comply with many of the restrictions noted above. The European financial markets have experienced volatility and adverse trends in recent years due to concerns about economic downturns, rising government debt levels and the possible default of government debt in several European countries, including, but not limited to, Cyprus, France, Greece, Ireland, Italy, Portugal, Spain and Ukraine. In order to prevent further economic deterioration, certain countries, without prior warning, can institute “capital controls.” Countries may use these controls to restrict volatile movements of capital entering and exiting their country. Such controls may negatively affect a Fund’s investments. A default or debt restructuring by any European country would adversely impact holders of that country’s debt and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed above. In addition, the credit ratings of certain European countries were recently downgraded. These downgrades may result in further deterioration of investor confidence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including countries that do not use the euro and non-EU member states. Responses to the financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest and may limit future growth and economic recovery or have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. The impact of these actions, especially if they occur in a disorderly fashion, is not clear but could be significant and far-reaching and could adversely impact the value of a Fund’s investments in the region. In a referendum held on June 23, 2016, the U.K. resolved to leave the EU. The referendum may introduce significant uncertainties and instability in the financial markets as the U.K. negotiates its exit from the EU. Although the precise timeframe for the U.K.’s withdrawal is uncertain, on March 29, 2017, the U.K. initiated the withdrawal process by sending a formal notice of the country’s intention to withdraw from the EU. An

agreement has been reached between the U.K. and the EU to continue negotiations on the U.K.’s exit from the EU. The outcome of negotiations remains uncertain. Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of a Fund's investments.

Risk of Investing in Japan. Japan may be subject to political, economic, nuclear, labor and other risks. Any of these risks, individually or in the aggregate, can impact an investment made in Japan.

Political Risk. Historically, Japan has had unpredictable national politics and may experience frequent political turnover. Future political developments may lead to changes in policy that might adversely affect a Fund’s investments. In addition, China has become an important trading partner with Japan. Japan’s political relationship with China, however, has been strained. Should political tension increase, it could adversely affect the Japanese economy and destabilize the region as a whole.

Risk of Investing in the Middle East. Many Middle Eastern countries have little or no democratic tradition, and the political and legal systems in such countries may have an adverse impact on a Fund. Many economies in the Middle East are highly reliant on income from the sale of oil or trade with countries involved in the sale of oil, and their economies are therefore vulnerable to changes in the market for oil and foreign currency values. As global demand for oil fluctuates, many Middle Eastern economies may be significantly impacted.

In addition, many Middle Eastern governments have exercised and continue to exercise substantial influence over many aspects of the private sector. In certain cases, a Middle Eastern country’s government may own or control many companies, including some of the largest companies in the country. Accordingly, governmental actions in the future could have a significant effect on economic conditions in Middle Eastern countries. This could affect private sector companies and a Fund, as well as the value of securities in the Fund's portfolio.

Certain Middle Eastern markets are in the earliest stages of development. As a result, there may be a high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries, as well as a high concentration of investors and financial intermediaries. Brokers in Middle Eastern countries typically are fewer in number and less capitalized than brokers in the U.S.

The legal systems in certain Middle Eastern countries also may have an adverse impact on a Fund. For example, the potential liability of a shareholder in a U.S. corporation with respect to acts of the corporation generally is limited to the amount of the shareholder’s investment. However, the notion of limited liability is less clear in certain Middle Eastern countries. A Fund therefore may be liable in certain Middle Eastern countries for the acts of a corporation in which it invests for an amount greater than its actual investment in that corporation. Similarly, the rights of investors in Middle Eastern issuers may be more limited than those of shareholders of a U.S. corporation. It may be difficult or impossible to obtain or enforce a legal judgment in a Middle Eastern country. Some Middle Eastern countries prohibit or impose substantial restrictions on investments in their capital markets, particularly their equity markets, by foreign entities such as a Fund. For example, certain countries may require governmental approval prior to investment by foreign persons or limit the amount of investment by foreign persons in a particular issuer. Certain Middle Eastern countries may also limit investment by foreign persons to only a specific class of securities of an issuer that may have less advantageous terms (including price) than securities of the issuer available for purchase by nationals of the relevant Middle Eastern country.

The manner in which foreign investors may invest in companies in certain Middle Eastern countries, as well as limitations on those investments, may have an adverse impact on the operations of a Fund. For example, in certain of these countries, a Fund may be required to invest initially through a local broker or other entity and then have the shares that were purchased re-registered in the name of a Fund. Re-registration in some instances may not be possible on a timely basis. This may result in a delay during which a Fund may be denied certain of its rights as an investor, including rights as to dividends or to be made aware of certain corporate actions. There also may be instances where a Fund places a purchase order but is subsequently informed, at the time of re-registration, that the permissible allocation of the investment to foreign investors has already been filled and, consequently, a Fund may not be able to invest in the relevant company.

Substantial limitations may exist in certain Middle Eastern countries with respect to a Fund’s ability to repatriate investment income or capital gains. A Fund could be adversely affected by delays in, or a refusal to grant, any required governmental approval for repatriation of capital, as well as by the application to a Fund of any restrictions on investment.

Certain Middle Eastern countries may be heavily dependent upon international trade and, consequently, have been and may continue to be negatively affected by trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which they trade. These countries also have been and may continue to be adversely impacted by economic conditions in the countries with which they trade. In addition, certain issuers located in Middle Eastern countries in which a Fund invests may operate in, or have dealings with, countries subject to sanctions and/or embargoes imposed by the U.S. government and the United Nations, and/or countries identified by the U.S. government as state sponsors of terrorism. As a result, an issuer may sustain damage to its reputation if it is identified as an issuer which operates in, or has dealings with, such countries. A Fund, as an investor in such issuers, will be indirectly subject to those risks.

Certain Middle Eastern countries have strained relations with other Middle Eastern countries due to territorial disputes, historical animosities, defense concerns or other reasons, which may adversely affect the economies of these Middle Eastern countries. Certain Middle Eastern countries experience significant unemployment, as well as widespread underemployment. There has also been a recent increase in recruitment efforts and an aggressive push for territorial control by terrorist groups in the region, which has led to an outbreak of warfare and hostilities. Warfare in Syria has spread to surrounding areas, including many portions of Iraq and Turkey. Such hostilities may continue into the future or may escalate at any time due to ethnic, racial, political, religious or ideological tensions between groups in the region or foreign intervention or lack of intervention, among other factors.

Risk of Investing in North America. A decrease in imports or exports, changes in trade regulations or an economic recession in any North American country can have a significant economic effect on the entire North American region and on some or all of the North American countries in which a Fund invests.

The U.S. is Canada's and Mexico's largest trading and investment partner. The Canadian and Mexican economies are significantly affected by developments in the U.S. economy. Since the implementation of NAFTA in 1994 among Canada, the U.S. and Mexico, total merchandise trade among the three countries has increased. However, political developments in the

U.S., including possible termination of NAFTA and imposition of tariffs by the U.S. on Canadian aluminum and steel, may have implications for the trade arrangements among the U.S., Mexico and Canada, which could negatively affect the value of securities held by a Fund. Policy and legislative changes in one country may have a significant effect on North American markets generally, as well as on the value of certain securities held by a Fund.

U.S. Economic Trading Partners Risk. The U.S. is a significant, and in some cases the most significant, trading partner of, or foreign investor in, the country or countries in which a Fund invests. As a result, economic conditions of such countries may be particularly affected by changes in the U.S. economy. The U.S. economy has recently experienced very difficult conditions and increased volatility, as well as significant adverse trends. While government intervention and recent legislation has been enacted to improve the U.S. economy, the recovery has been fragile and modest. A decrease in U.S. imports, new trade and financial regulations, changes in the U.S. dollar exchange rate or an economic slowdown in the U.S. may have a material adverse effect on a country’s economic conditions and, as a result, securities to which a Fund has exposure.

Risk of Investing in the Aerospace and Defense Industry. The aerospace and defense industry can be significantly affected by government defense and aerospace regulation and spending policies. The aerospace industry in particular has recently been affected by adverse economic conditions and consolidation within the industry.

Risk of Investing in the Automotive Sub-Industry. The automotive sub-industry can be highly cyclical, and companies in the automotive sub-industry may suffer periodic losses. The automotive sub-industry is also highly competitive and there may be, at times, excess capacity in the global and domestic automotive sub-industry. Over the last several decades, the U.S. automotive sub-industry has experienced periodic downturns; certain automotive companies required stimulus from the U.S. government, while others formed strategic industry alliances in order to weather the substantially difficult market conditions. In general, the automotive sub-industry is susceptible to labor disputes, product defect litigation, patent expiration, increased pension liabilities, rise in material or component prices and changing consumer tastes.

Risk of Investing in the Biotechnology Industry. Biotechnology companies depend on the successful development of new and proprietary technologies. There can be no assurance that the development of new technologies will be successful or that intellectual property rights will be obtained with respect to new technologies. The loss or impairment of intellectual property rights may adversely affect the profitability of biotechnology companies. In addition, companies in the biotechnology industry spend heavily on research and development and their products or services may not prove commercially successful or may become obsolete quickly. The risks of high development costs may be exacerbated by the inability to raise prices as a result of managed care pressure, government regulation or price controls. Biotechnology companies can suffer persistent losses during the transition of new products from development to production or when products are or may be subject to regulatory approval processes or regulatory scrutiny and, as a consequence, the earnings of biotechnology companies may be erratic. Companies in the biotechnology industry are also exposed to the risk that they will be subject to products liability claims. Companies involved in the biotechnology industry may be subject to extensive government regulations by the U.S. Food and Drug Administration, the U.S. Environmental Protection Agency and the U.S. Department of Agriculture, among other foreign and domestic regulators. Such regulation may significantly affect and limit biotechnology research, product development and approval of products.

Risk of Investing in the Clean Energy Sub-Industry. Many clean energy companies are involved in the development and commercialization of new technologies, which may be subject to delays resulting from budget constraints and technological difficulties. Clean energy companies may be highly dependent upon government subsidies and contracts with government entities, and may be negatively affected if such subsidies or contracts are unavailable. Clean energy companies may depend on the successful development of new and proprietary technologies. There can be no assurance that the development of new technologies will be successful or that intellectual property rights will be obtained with respect to new technologies. The loss or impairment of intellectual property rights may adversely affect the profitability of clean energy companies. In addition,

seasonal weather conditions, fluctuations in supply of, and demand for, clean energy products, changes in energy prices, international political events, the success of project development and change in government regulatory policies may cause fluctuations in the performance of clean energy companies and the prices of their securities.

Risk of Investing in the Commercial and Professional Services Industry. The success of commercial and professional service providers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, availability of qualified personnel and corporate demand. The commercial and professional services industry depends heavily on corporate spending. Companies in the commercial and professional services industry may be subject to severe competition, which may also have an adverse impact on their profitability.

Risk of Investing in the Consumer Goods Industry. Companies in the consumer goods industry include companies involved in the design, production or distribution of goods for consumers, including food, household, home, personal and office products, clothing and textiles. The success of the consumer goods industry is tied closely to the performance of the domestic and international economy, interest rates, exchange rates, competition, consumer confidence and consumer disposable income. The consumer goods industry may be affected by trends, marketing campaigns and other factors affecting consumer demand. Governmental regulation affecting the use of various food additives may affect the profitability of certain companies in the consumer goods industry. Moreover, international events may affect food and beverage companies that derive a substantial portion of their net income from foreign countries. In addition, tobacco companies may be adversely affected by new laws, regulations and litigation. Many consumer goods may be marketed globally, and consumer goods companies may be affected by the demand and market conditions in other countries and regions. Companies in the consumer goods industry may be subject to severe competition, which may also have an adverse impact on their profitability. Changes in demographics and consumer preferences may affect the success of consumer products.

Risk of Investing in the Consumer Services Industry. The success of consumer product manufacturers and retailers (including food and drug retailers, general retailers, media, and travel and leisure) is tied closely to the performance of the domestic and international economy, interest rates, exchange rates, competition and consumer confidence. The consumer services industry depends heavily on disposable household income and consumer spending. Companies in the consumer services industry may be subject to severe competition, which may also have an adverse impact on their profitability. Changes in demographics and consumer preferences may affect the success of consumer service providers.

Most financial companies are subject to extensive governmental regulation, which limits their activities and may affect their ability to earn a profit from a given line of business. Government regulation may change frequently and may have significant adverse consequences for companies in the financials sector, including effects not intended by the regulation. Direct governmental intervention in the operations of financial companies and financial markets may materially and adversely affect the companies in which a Fund invests, including legislation in many countries that may increase government regulation, repatriation and other intervention. The impact of governmental intervention and legislative changes on any individual financial company or on the financials sector as a whole cannot be predicted. The valuation of financial companies has been and continues to be subject to unprecedented volatility and may be influenced by unpredictable factors, including interest rate risk and sovereign debt default. Certain financial businesses are subject to intense competitive pressures, including market share and price competition. Financial companies in foreign countries are subject to market specific and general regulatory and interest rate concerns. In particular, government regulation in certain foreign countries may include taxes and controls on interest rates, credit availability, minimum capital requirements, bans on short sales, limits on prices and restrictions on currency transfers. In addition, companies in the financials sector may be the targets of hacking and potential theft of proprietary or customer information or disruptions in service, which could have a material adverse effect on their businesses.

Risk of Investing in the Home Construction Industry. The home construction industry may be significantly affected by changes in government spending, zoning laws, economic conditions, interest rates, commodity prices, consumer confidence and spending, taxation, demographic patterns, real estate values, overbuilding, housing starts, and new and existing home sales. Rising interest rates, reductions in mortgage availability to consumers, increasing foreclosure rates or increases in the costs of owning a home could reduce the market for new homes and adversely affect the profitability of home construction companies. Different segments of the home construction industry can be significantly affected by environmental clean-up costs and catastrophic events such as earthquakes, hurricanes and terrorist acts. Home construction companies may lack diversification, due to ownership of a limited number of properties and concentration in a particular geographic region or property type.

Risk of Investing in the Industrials Sector. The value of securities issued by companies in the industrials sector may be adversely affected by supply of and demand for both their specific products or services and for industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events and economic conditions may affect the performance of companies in the industrials sector. The industrials sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors. Aerospace and defense companies, a component of the industrials sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on government demand for their products and services. Thus, the financial condition of, and investor interest in, aerospace and defense companies are heavily influenced by governmental defense spending policies, which are typically under pressure from efforts to control government budgets. Transportation stocks, a component of the industrials sector, are cyclical and can be significantly affected by economic changes, fuel prices, labor relations and insurance costs. Transportation companies in certain countries may also be subject to significant government regulation and oversight, which may adversely affect their businesses. For example, commodity price declines and unit volume reductions resulting from an over-supply of materials used in the industrials sector can adversely affect the sector. Furthermore, companies in the industrials sector may be subject to liability for environmental damage, product liability claims, depletion of resources, and mandated expenditures for safety and pollution control.

Risk of Investing in the Infrastructure Industry. Companies in the infrastructure industry may be subject to a variety of factors that could adversely affect their business or operations, including high interest costs in connection with capital construction programs, high degrees of leverage, costs associated with governmental, environmental and other regulations, the effects of economic slowdowns, increased competition from other providers of services, uncertainties concerning costs, the level of government spending on infrastructure projects, and other factors. Infrastructure companies may be adversely affected by commodity price volatility, changes in exchange rates, import controls, depletion of resources, technological developments, and labor relations. There is also the risk that corruption may negatively affect publicly funded infrastructure projects, especially in emerging markets, resulting in delays and cost overruns. Infrastructure issuers can be significantly affected by government spending policies because companies involved in this industry rely to a significant extent on U.S. and other government demand for their products.

Infrastructure companies in the oil and gas industry may be adversely affected by government regulation or world events in the regions where the companies operate (e.g., expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and repatriation of capital, military coups, social unrest, violence or labor unrest). Infrastructure companies may have significant capital investments in, or engage in transactions involving, emerging market countries, which may heighten these risks.

Interest Rate Risk. Rising interest rates could result in higher costs of capital for infrastructure companies, which could negatively impact their ability to meet payment obligations.

Leverage Risk. Infrastructure companies can be highly leveraged, which increases investments risk and other risks normally associated with debt financing and could adversely affect an infrastructure company's operations and market value in periods of rising interest rates.

Oil and Gas Risk. The profitability of oil and gas companies is related to worldwide energy prices, exploration, and production spending.

Utilities Risk. Utilities companies face intense competition, both domestically and internationally, which may have an adverse effect on their profit margins. The rates charged by regulated utility companies are subject to review and limitation by governmental regulatory commissions.

Risk of Investing in the Insurance Industry. The insurance industry is subject to extensive government regulation in some countries and can be significantly affected by changes in interest rates, general economic conditions, price and marketing competition, the imposition of premium rate caps or other changes in government regulation or tax law. Different segments of the insurance industry can be significantly affected by changes in mortality and morbidity rates, environmental clean-up costs and catastrophic events such as earthquakes, hurricanes and terrorist acts.

Risk of Investing in the Media Sub-Industry. Companies in the media sub-industry may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology. Media companies are subject to risks that include cyclicality of revenues and earnings, a potential decrease in the discretionary income of targeted individuals, changing consumer tastes and interests, competition

in the industry and the potential for increased state and federal regulation. Advertising spending is an important source of revenue for media companies. During economic downturns, advertising spending typically decreases and, as a result, media companies tend to generate less revenue.

Risk of Investing in the Medical Equipment Industry. Many companies in the medical equipment industry are heavily dependent on patent protection, and the expiration of patents may adversely affect the profitability of these companies. Companies in the medical equipment industry may be subject to extensive litigation based on product liability and similar claims as well as competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. The profitability of some medical equipment companies may be dependent on a relatively limited number of products. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the medical equipment industry are subject to regulatory approvals, and the process of obtaining such approvals is long and costly.

Risk of Investing in the Natural Resources Industry. The profitability of companies in the natural resources industry can be affected by worldwide energy prices, limits on exploration, and production spending. Companies in the natural resources industry are affected by government regulation, world events and economic conditions. Companies in the natural resources industry are at risk for environmental damage claims. Companies in the natural resources industry could be adversely affected by commodity price volatility, changes in exchange rates, imposition of import controls and increased competition. Companies in the natural resources industry may be adversely affected by depletion of natural resources, technological developments, and labor relations.

Risk of Investing in the Oil and Gas Industry. Companies in the oil and gas industry are strongly affected by the levels and volatility of global energy prices, oil and gas supply and demand, government regulations and policies, oil and gas production and conservation efforts and technological change. The oil and gas industry is cyclical and from time to time may experience a shortage of drilling rigs, equipment, supplies or qualified personnel, or due to significant demand, such services may not be available on commercially reasonable terms. Prices and supplies of oil and gas may fluctuate significantly over short and long periods of time due to national and international political changes, OPEC policies, changes in relationships among OPEC members and between OPEC and oil-importing nations, the regulatory environment, taxation policies, and the economies of key energy-consuming countries. Disruptions in the oil sub-industry or shifts in energy consumption may significantly impact companies in this industry. For instance, significant oil and gas deposits are located in emerging market countries where corruption and security may raise significant risks, in addition to the other risks of investing in emerging markets. In addition, the Middle East, where many companies in the oil and gas industry may operate, has recently experienced widespread social unrest. Oil and gas companies operate in a highly competitive industry, with intense price competition. A significant portion of their revenues may depend on a relatively small number of customers, including governmental entities and utilities.

Risk of Investing in the Oil Equipment and Services Sub-Industry. The profitability of companies in the oil equipment and services sub-industry is related to worldwide energy prices, exploration, and production spending. Companies in the oil equipment and services sub-industry may be adversely affected by natural disasters or other catastrophes. Companies in the oil equipment and services sub-industry may be at risk for environmental damage claims and other types of litigation. Companies in the oil equipment and services sub-industry may be adversely affected by changes in exchange rates, interest rates, economic conditions, tax treatment, imposition of import controls and increased competition. Companies in the oil equipment and services sub-industry may be adversely affected by oil deposits, technological developments and labor relations. Companies in the oil equipment and services sub-industry may be adversely affected by government regulation and intervention, negative perception and world events in the regions that the companies operate (e.g., expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and repatriation of capital, military coups, social unrest, violence or labor unrest). Companies in the oil equipment and services sub-industry may have significant capital investments in, or engage in transactions involving, emerging market countries, which may heighten these risks.

Risk of Investing in the Pharmaceuticals Industry. Companies in the pharmaceuticals industry are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. The profitability of some companies in the pharmaceuticals industry may be dependent on a relatively limited number of products. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the pharmaceuticals industry are subject to government approvals, regulation and reimbursement rates. The process of obtaining government approvals may be long and costly. Many companies in the pharmaceuticals industry are

heavily dependent on patents and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Companies in the pharmaceutical industry may be subject to extensive litigation based on product liability and similar claims.

Risk of Investing in the Real Estate Industry. Companies in the real estate industry include companies that invest in real estate, such as REITs, real estate holding companies or real estate development companies (collectively, “Real Estate Companies”). Investing in Real Estate Companies exposes investors to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which Real Estate Companies are organized and operated. The real estate industry is highly sensitive to general and local economic conditions and developments, and characterized by intense competition and periodic overbuilding. Investing in Real Estate Companies involves various risks. Some risks that are specific to Real Estate Companies are discussed in greater detail below.

Property Risk. Real Estate Companies may be subject to risks relating to functional obsolescence or reduced desirability of properties; extended vacancies due to economic conditions and tenant bankruptcies; catastrophic events such as earthquakes, hurricanes and terrorist acts; and casualty or condemnation losses. Real estate income and values also may be greatly affected by demographic trends, such as population shifts or changing tastes and values, or increasing vacancies or declining rents resulting from legal, cultural, technological, global or local economic developments.

Liquidity Risk. Investing in Real Estate Companies may involve risks similar to those associated with investing in small-capitalization companies. Real Estate Company securities, like the securities of small-capitalization companies, may be more volatile than, and perform differently from, shares of large-capitalization companies. There may be less trading in Real Estate Company shares, which means that buy and sell transactions in those shares could have a magnified impact on share price, resulting in abrupt or erratic price fluctuations. In addition, real estate is relatively illiquid, and, therefore, a Real Estate Company may have a limited ability to vary or liquidate properties in response to changes in economic or other conditions.

U.S. Tax Risk. Certain U.S. Real Estate Companies are subject to special U.S. federal tax requirements. A REIT that fails to comply with such tax requirements may be subject to U.S. federal income taxation, which may affect the value of the REIT and the characterization of the REIT’s distributions. The U.S. federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. A REIT that successfully maintains its qualification may still become subject to U.S. federal, state and local taxes, including excise, penalty, franchise, payroll, mortgage recording, and transfer taxes, both directly and indirectly through its subsidiaries.

Risk of Investing in the Retail Industry. The retail industry may be affected by changes in domestic and international economies, consumer confidence, disposable household income and spending, and consumer tastes and preferences. Companies in the retail industry face intense competition, which may have an adverse effect on their profitability. The success of companies in the retail industry may be strongly affected by social trends, marketing campaigns and public perceptions. Companies in the retail industry may be dependent on outside financing, which may be difficult to obtain. Many of these companies are dependent on third party suppliers and distribution systems. Retail companies may be unable to protect their intellectual property rights or may be liable for infringing the intellectual property rights of others.

technology companies in foreign markets. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face product obsolescence due to rapid technological developments and frequent new product introduction, changes in consumer and business purchasing patterns, unpredictable changes in growth rates and competition for the services of qualified personnel. In addition, a rising interest rate environment tends to negatively affect companies in the technology sector because, in such an environment, those companies with high market valuations may appear less attractive to investors, which may cause sharp decreases in the companies’ market prices. Companies in the technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. The technology sector may also be adversely affected by changes or trends in commodity prices, which may be influenced or characterized by unpredictable factors. Finally, while all companies may be susceptible to network security breaches, certain companies in the technology sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.

Risk of Investing in the Transportation Infrastructure Industry. Issuers in the transportation infrastructure industry can be significantly affected by economic changes, fuel prices, labor relations, technology developments, exchange rates, industry competition, insurance costs and deteriorating public infrastructure, such as bridges, roads, rails, ports and airports. Transportation companies in certain countries may also be subject to significant government regulation and oversight, which may adversely affect their businesses. Other risk factors that may affect the transportation infrastructure industry include the risk of increases in fuel and other operating costs and the effects of regulatory changes or other government decisions. Companies in the transportation infrastructure industry may be adversely affected by adverse weather, acts of terrorism or catastrophic events, such as air accidents, train crashes or tunnel fires. Companies in the transportation infrastructure industry may also be subject to the risk of widespread disruption of technology systems and increasing equipment and operational costs.

There are substantial differences among the regulatory practices and policies of various jurisdictions, and any regulatory agency may make major shifts in policy from time to time. There is no assurance that regulatory authorities will, in the future, grant rate increases. Additionally, existing and possible future regulatory legislation may make it even more difficult for utilities to obtain adequate relief. Certain of the issuers of securities held in a Fund's portfolio may own or operate nuclear generating facilities. Governmental authorities may from time to time review existing policies and impose additional requirements governing the licensing, construction and operation of nuclear power plants. Prolonged changes in climate conditions can also have a significant impact on both the revenues of an electric and gas utility as well as the expenses of a utility, particularly a hydro-based electric utility.

Certain utility companies have experienced full or partial deregulation in recent years. These utility companies are frequently more similar to industrial companies in that they are subject to greater competition and have been permitted by regulators to diversify outside of their original geographic regions and their traditional lines of business. As a result, some companies may be forced to defend their core business and may be less profitable. Deregulation may also permit a utility company to expand outside of its traditional lines of business and engage in riskier ventures.

Construction and Maintenance of the Underlying Indexes

Descriptions of the Underlying Indexes are provided below.

The Dow Jones Indexes

Component Selection Criteria. Securities of companies listed on a major U.S. exchange (such as the New York Stock Exchange, Inc. (“NYSE”), the NYSE MKT Equities or the NASDAQ) are considered for inclusion in the Underlying Indexes, with the following general rules and exceptions. Foreign issues, including ADRs and GDRs, non-common equity issues such as preferred stocks, convertible notes, warrants, rights, closed-end funds, trust receipts, limited liabilities companies, royalty trusts, units, limited partnerships, over-the-counter bulletin boards and pink sheet stocks generally are not eligible for inclusion in the indexes.

Issue Changes. Each Underlying Index is reviewed and rebalanced quarterly to maintain accurate representation of the market segment represented by the Underlying Index. Securities that are removed from an Index between reconstitution dates are not replaced.

Index Maintenance. Maintaining the Underlying Indexes includes monitoring and completing the adjustments for additions and deletions to each Underlying Index, share changes, stock splits, stock dividends, and stock price adjustments due to restructuring and spin-offs. Generally (other than with respect to the Dow Jones Select Sector and Subsector Indexes (as defined below)) each component security in an Underlying Index is limited to a maximum market capitalization of 25% of the index weight, and sum of the weights of all component securities greater than 5% of the index is limited to 50% of the index total. If components fail either rule, their market capitalization will be reduced to meet the set guidelines.

Weighting. The component stocks are weighted according to the total value of their outstanding shares. The impact of a component’s price change is proportional to the issue’s total market value, which is the share price multiplied by the number of shares outstanding. Each Underlying Index is adjusted to reflect changes in capitalization resulting from mergers,

acquisitions, stock rights, substitutions and other capital events. Each of the Underlying Indexes (except the Dow Jones Select Sector and Subsector Indexes) as described below, is a free-float adjusted market capitalization-weighted index, so the impact of a component’s price change is proportional to the component’s free-float adjusted market value, which is the share price multiplied by the number of float-adjusted shares outstanding. S&P Dow Jones Indices LLC (“SPDJI”) defines the free-float of a security as the proportion of shares outstanding that are deemed to be available for purchase in the public equity markets by investors. In practice, limitations on free-float available to investors include: cross ownership (shares that are owned by other companies), ownership by governments (central or municipal) or their agencies, certain substantial levels of private ownership (by individuals, families or charitable trusts and foundations), and restricted shares. Under SPDJI's free-float adjustment methodology, a company’s outstanding shares are adjusted if, and only if, an entity in any of the four qualified categories listed above owns 5% or more of the company. The company’s shares will not be adjusted if the block ownership is less than 5%. A constituent’s inclusion factor is equal to its estimated percentage of free-float shares outstanding. For example, a constituent security with a free-float of 67% will be included in the index at 67% of its market capitalization. However, a company’s outstanding shares are not adjusted by institutional investors’ holdings, which include, but are not limited to, the following categories: custodian nominees, trustee companies, mutual funds (open-end and closed-end funds), and other investment companies.

Index Availability. The Underlying Indexes are calculated continuously and are available from major data vendors.

Component Selection Criteria Applicable to Dow Jones Subsector Indexes. The following indexes are collectively referred to herein as the “Dow Jones Select Sectors Indexes”: Dow Jones U.S. Select Aerospace & Defense Index, Dow Jones U.S. Select Health Care Providers Index, Dow Jones U.S. Select Home Construction Index, Dow Jones U.S. Select Insurance Index, Dow Jones U.S. Select Investment Services Index, Dow Jones U.S. Select Medical Equipment Index, Dow Jones U.S. Select Oil Equipment & Services Index, Dow Jones U.S. Select Oil Exploration & Production Index, Dow Jones U.S. Select Pharmaceuticals Index, Dow Jones U.S. Select Regional Banks Index and Dow Jones U.S. Select Telecommunications Index and the “Dow Jones Subsector Index”: Dow Jones U.S. Real Estate Index. On a quarterly basis, SPDJI conducts reviews of the float-adjusted market capitalizations and weightings of the securities in each Dow Jones Subsector Index. Other than the Dow Jones U.S. Select Home Construction Index, the Dow Jones U.S. Select Regional Banks Index and the Dow Jones U.S. Select Telecommunications Index, on the last business day of the month prior to the quarterly review, a security must have a $500 million float-adjusted market capitalization to be added to a Dow Jones Select Sector and Subsector Index; securities with a float-adjusted market capitalization below $250 million will be removed from the applicable Dow Jones Select Sector and Subsector Index.

For the Dow Jones U.S. Select Home Construction Index and the Dow Jones U.S. Select Telecommunications Index, on the last business day of the month prior to the quarterly review, a security must have a $500 million float-adjusted market capitalization to be added to a Dow Jones Select Sectors Index; securities with a float-adjusted market capitalization below $100 million will be removed from the applicable Dow Jones Select Sectors Index.

For the Dow Jones U.S. Select Regional Banks Index, index composition is reconstituted annually as part of the June rebalancing. However, if a constituent is deleted from the Dow Jones U.S. Banks Index (i.e. the index selection universe) during a quarterly rebalancing, it is also deleted from the Dow Jones U.S. Select Regional Banks Index at that quarter’s rebalancing. A company is excluded from the Dow Jones U.S. Select Regional Banks Index if its three-year average total assets account for more than 5% of the three-year average total assets of the index selection universe. Any company that failed this asset screen during the previous annual reconstitution and that accounts for at least 4% of the selection universe’s three-year average total assets at the next review will continue to be excluded from the index.

After the close of trading on the NYSE on the second Friday in March, June, September and December, each Dow Jones Select Sector and Subsector Index’s composition is adjusted to meet the following concentration limits:

•	No single Underlying Index component may have a weight greater than 25% of the Index.
•	The sum of the weights of the Index components that are individually greater than 5% may not be greater than 45% of the Index.
•	The sum of the weights of the five largest Index components may not be greater than 65% of the Index.

The FTSE NAREIT Indexes

Component Selection Criteria. The FTSE NAREIT U.S. Real Estate Indexes (“FTSE NAREIT Indexes”) are primarily rule-based, but are also monitored by the FTSE NAREIT Index Advisory Committee. All tax-qualified REITs that are listed on the NYSE, the NYSE Amex Equities or the NASDAQ are eligible for inclusion in the FTSE NAREIT Indexes. Potential constituents for the FTSE NAREIT All Mortgage Capped Index and the FTSE NAREIT All Residential Capped Index are determined by sector classifications of constituents in the FTSE NAREIT Composite Index. The FTSE NAREIT Indexes are reviewed for changes in free-float on a quarterly basis in March, June, September and December for companies which do not qualify for fast entry, but which meet the criteria for eligible securities set out in the index rules. Meetings to review the constituents will be held on the Thursday following the first Friday of March, June, September and December. The review is based on data at the close of business on the last trading day of February, May, August and November. The FTSE NAREIT Index Advisory Committee meets quarterly, in March, June, September and December or more frequently, if required.

When calculating index component weights, component companies’ shares are adjusted for available free-float. In general, shares held by governments, corporations, strategic partners, or other control groups are excluded from a constituent company’s outstanding shares.

Index Maintenance. FTSE International Limited (“FTSE”) is responsible for the daily operation of the FTSE NAREIT Indexes. FTSE will maintain records of the market capitalization of all constituents, and will make changes to the constituents and their weightings in accordance with index rules. FTSE will also carry out the periodic company reviews of the FTSE NAREIT Indexes and implement the resulting constituent changes as required by index rules.

Issue Changes. New issues of companies that do not qualify for “Fast Entry” but meet the criteria for eligible securities and have been listed for over 20 business trading days will be eligible for inclusion in the FTSE NAREIT Indexes. The data will be compiled as of the close of business on the last business day in February, May, August and November. The changes will be effective after the close of business on the third Friday in March, June, September and December.

If a constituent is delisted, or ceases to have a firm quotation, or is subject to a takeover offer which has been declared wholly unconditional, it will be removed from the indexes of which it is a constituent.

Index Availability. The FTSE NAREIT Indexes are calculated continuously during normal trading hours of the NASDAQ, NYSE Amex Equities and NYSE, and are closed on U.S. holidays.

Exchange Rates and Pricing. The prices used to calculate the FTSE NAREIT Indexes are the Reuters daily closing prices or those figures accepted as such.

JPX-Nikkei Index 400

Number of Components: approximately 399

Index Description. The JPX-Nikkei Index 400 was jointly developed by Japan Exchange Group, Inc. and Tokyo Stock Exchange, Inc. (“TSE”) (collectively referred to as the “JPX Group”) and Nikkei Inc. (the “Nikkei”). The JPX-Nikkei Index 400 is constructed based on market capitalization adjusted by free-float weight. Free-float weight is the percentage of listed shares deemed to be available for trading in the market. As a general matter, shares held by the top 10 major shareholders, treasury and other similar shares, shares held by board members and other representatives, and other shares deemed by the JPX Group and the Nikkei to be unavailable for trading in the market are considered to be non-free float shares.

Eligibility. Underlying Index eligibility is limited to (i) common stocks traded primarily on the TSE, including the First Section, Second Section, Mothers and JASDAQ Securities Exchange (“JASDAQ”) (in principle) and (ii) TSE First Section, TSE Second Section, Mothers or JASDAQ-listed securities other than common stocks that are regarded by the JPX Group and the Nikkei as equivalent to common stocks in each case if their inclusion is deemed to be particularly necessary- as determined by the JPX Group and the Nikkei.

Index Maintenance and Issue Changes. The constituents are reviewed annually at the end of August. Selection as particularly necessary is based on: (i) trading value over the past three years, (ii) market value on the selection base date (the end of June), (iii) scoring by stock by three-year average returns on equity, cumulative operating profit and market value on the selection base date using specified weightings and (iv) qualitative factors tied to corporate governance and disclosure. The JPX Group and the Nikkei have indicated that securities will be dropped from the Underlying Index during the year if they are delisted or are the subject of a merger or bankruptcy and that new securities will not be added to replace dropped securities until the annual review. As a result, at different points throughout the calendar year, the Underlying Index may have less than 400 components.

Index Availability. Information regarding adjustments to the Underlying Index and other related data is available through Tokyo Market Information service provided by TSE.

NASDAQ Biotechnology Index^®

Number of Components: approximately 193

Index Description. The NASDAQ Biotechnology Index is designed to track the performance of a set of securities listed on NASDAQ that are classified as either biotechnology or pharmaceutical according to the Industry Classification Benchmark (ICB) and that also meet other eligibility criteria determined by The NASDAQ OMX Group, Inc. (“NASDAQ OMX”). The NASDAQ Biotechnology Index is a modified market capitalization-weighted index.

Eligibility. Underlying Index eligibility is limited to common stocks, ordinary shares, ADRs, and shares of beneficial interest or limited partnership interests that are listed on NASDAQ. Companies must also meet certain minimum market capitalization, liquidity, and other criteria to be eligible for inclusion in the Underlying Index.

Index Maintenance and Issue Changes. Index securities are evaluated annually in December. Generally, the list of additions and deletions is publicly announced via a press release in the early part of December. Security additions and deletions are made effective after the close of trading on the third Friday in December. Moreover, if at any time during the year other than the evaluation, an index security no longer meets the eligibility criteria, or is otherwise determined to have become ineligible for continued inclusion in the Underlying Index, the security is removed from the Underlying Index and will not be replaced.

Quarterly Index Rebalancing. The Underlying Index employs a modified market capitalization-weighting methodology. At each quarter, the Index is rebalanced such that the maximum weight of any index security does not exceed 8% and no more than 5 securities are at that cap. The excess weight of any capped security is distributed proportionally across the remaining index securities. If after redistribution, any of the 5 highest ranked index securities are weighted below 8%, these securities are not capped. Next, any remaining index securities in excess of 4% are capped at 4% and the excess weight is redistributed proportionally across the remaining index securities. The process is repeated, if necessary, to derive the final weights.

The modified market capitalization-weighting methodology is applied to the capitalization of each index security using the last sale price of the security at the close of trading on the last trading day in February, May, August and November and after applying quarterly changes to the total shares outstanding. The changes are effective after trading on the third Friday in March, June, September and December.

NASDAQ OMX may, from time to time, exercise reasonable discretion as it deems appropriate in order to ensure Underlying Index integrity.

NYSE^® FactSet U.S. Infrastructure Index

Number of Components: approximately 158

Index Description. The NYSE FactSet U.S. Infrastructure Index is designed to measure the performance of equity securities of U.S. companies involved in U.S. focused infrastructure activities (as determined by the index provider of the Underlying Index).

Companies are eligible to be included in the Underlying Index if they are classified to be under one of the 95 infrastructure-related industries as defined by FactSet Revere Business Industry Classification System (“RBICS”). Each company in the Underlying Index is classified as either Category 1 or Category 2, where Category 1 companies are infrastructure enablers and Category 2 are infrastructure asset owners and operators.

Infrastructure enablers are potential beneficiaries of infrastructure investment in the U.S. Category 1 companies in the Underlying Index include companies in construction and engineering services, machineries and materials. Infrastructure asset owners and operators are companies associated with traditional equity infrastructure investing, which generally exhibit characteristics such as stable cash flows, high barrier to entry, and inflation hedge. Category 2 companies in the Underlying Index include companies in energy transportation and storage, railroad transportation, and utilities.

The Underlying Index will be reviewed and reconstituted annually in March each year. Constituent weights of the Underlying Index are rebalanced quarterly in March, June, September and December.

Eligibility. The following rules are used for the initial constituent selection and ongoing reconstitution:

•	Underlying Index eligibility is limited to common stocks traded primarily on the New York Stock Exchange (“NYSE”), NYSE American and NASDAQ, excluding master limited partnerships (MLPs), royalty trusts, business development companies (BDCs), and American depository receipts (ADRs).
•	Initial Public Offering (“IPO”) securities newer than 3 month relative to reconstitution day are excluded.
•	The securities must have a minimum float-adjusted market capitalization of U.S. $300 million or greater, and three-month Average Daily Trading Value (“ADTV”) of U.S. $1 million or greater on selection day.

Existing constituents may remain in the Underlying Index if they have a minimum float-adjusted market capitalization of U.S. $225 million or greater, and a three-month ADTV of U.S. $0.75 million or greater on selection day.

•	The securities must be classified as having a focus (deriving 50% or more revenues) in one of the 95 infrastructure-related industries as defined by RBICS in either Category 1 or 2, where Category 1 companies are infrastructure enablers and Category 2 companies are infrastructure asset owners and operators.
•	An eligible company must derive 50% or more of its annual revenues from the U.S. to be included in the Underlying Index.

Existing constituents may remain in the Underlying Index if they derive 40% or more its annual revenues from the U.S.

•	If a company has multiple share classes, only the most liquid issue based on the highest three-month ADTV on selection day will be included.

The PHLX Semiconductor Sector Index

Number of Components: approximately 30

Index Description. The PHLX Semiconductor Sector Index is designed to track the performance of U.S.-traded securities of a set of companies engaged in the design, distribution, manufacture and sale of semiconductors.

Index Calculation. The Underlying Index is a modified capitalization-weighted index. The value of the Underlying Index equals the aggregate value of the Underlying Index share weights, also known as the Index Shares, of each of the Underlying Index securities multiplied by each such security’s Last Sale Price¹, and divided by the divisor of the Underlying Index. The divisor serves the purpose of scaling such aggregate index value to a lower order of magnitude which is more desirable for reporting purposes. The Underlying Index began on December 1, 1993 at a base value of 100.00, as adjusted.

The formula for index value is as follows:

•	Aggregate Adjusted Market Value/Divisor

The formula for the divisor is as follows:

•	(Market Value after Adjustments/Market Value before Adjustments) X Divisor before Adjustments

Two versions of the Underlying Index are calculated – a price return index and a total return index.

The price return index (NASDAQ: SOX) is ordinarily calculated without regard to cash dividends on Underlying Index securities.

The total return index (NASDAQ: XSOX) reinvests cash dividends on the ex-date.

Both Indexes reflect extraordinary cash distributions. The total return index was synchronized to the value of the price return index at the close on December 22, 2009.

The Underlying Index is calculated during the trading day and is disseminated once per second from 09:30:01 to 17:16:00 ET. The closing value of the Underlying Index may change up until 17:15:00 ET due to corrections to the Last Sale Price of the Underlying Index securities. If trading in an Underlying Index security is halted on its primary listing market, the most recent

Last Sale Price is used for all index computations until trading on such market resumes. Likewise, the most recent Last Sale Price is used if trading in a security is halted on its primary listing market before the market is open.

Initial Security Eligibility Criteria. Index eligibility is limited to specific security types only. The security types eligible for the Underlying Index include common stocks, ordinary shares, ADRs, shares of beneficial interest or limited partnership interests.

To be eligible for inclusion in the Underlying Index, a security must meet the following criteria:

•	a security must be listed on NASDAQ, the NYSE, or NYSE MKT;
•	the issuer of the security must be classified as a company whose primary business is involved in the design, distribution, manufacture, and sale of semiconductors under the Industry Classification Benchmark² code 9576;
•	one security per issuer is permitted. If an issuer has multiple securities, the security with the largest market capitalization will be selected for possible inclusion in the Underlying Index;
•	the security must have a minimum market capitalization of at least $100 million;
•	the security must have traded at least 1.5 million shares in each of the last six months;
•	the security must have listed options on a recognized options market in the U.S. or be eligible for listed-options trading on a recognized options market in the U.S.;
•	the security may not be issued by an issuer currently in bankruptcy proceedings;
•	the issuer of the security may not have entered into a definitive agreement or other arrangement which would likely result in the security no longer being Index eligible;
•	the issuer of the security may not have annual financial statements with an audit opinion that is currently withdrawn;
•	the issuer of the security must have been “seasoned” on a recognized market for at least 3 months; and
•	one security per issuer is permitted. If an issuer has multiple securities, the security with the largest market capitalization will be selected for possible inclusion in the Index.

Index Evaluation. The Underlying Index securities are evaluated annually in September. The above Eligibility Criteria are applied using market data as of the end of July. Securities meeting the Criteria are then ranked by market capitalization. The top 30 securities by market capitalization are included in the Underlying Index. Security additions and deletions are made effective after the close of trading on the third Friday in September.

Additionally, if at any time during the year other than during the ranking review, an Underlying Index security is determined to have become ineligible for continued inclusion in the Underlying Index, or at the end of January, April, July or October does not have a Last Sale Price of at least $3.00, then the security will be replaced with the largest market capitalization security not currently in the Index and that both meets the Eligibility Criteria listed above and has at least a $3.00 Last Sale Price. Ordinarily, a security will be removed from the Index at its Last Sale Price. If, however, at the time of its removal a security is halted from trading on its primary listing market and an official closing price cannot be readily determined, the security may, in NASDAQ’s discretion, be removed at a zero price. The zero price will be applied to the security after the close of the market but prior to the time the official closing value of the Index is disseminated, which is ordinarily 17:16:00 ET.

Index Maintenance. Changes in the price and/or Index Shares driven by corporate events such as stock dividends, stock splits and certain spin-offs and rights issuances are adjusted on the ex-date. If the change in total shares outstanding arising from other corporate actions is greater than or equal to 10.0%, the change is made as soon as practicable. (If a security is a depositary receipt, the total shares outstanding is the actual depositary shares outstanding as reported by the depositary banks.) Otherwise, if the change in total shares outstanding is less than 10.0%, then all such changes are accumulated through the end of February, May, August and November and made effective at one time on a quarterly basis after the close of trading on the third Friday in each of March, June, September and December. The Index Shares are adjusted by the same percentage amount by which the total shares outstanding have changed.

A special cash dividend announced by the listing exchange will result in an adjustment to the Last Sale Price of an Underlying Index security prior to market open on the ex-date for the special amount distributed. A special dividend may also be referred to as extra, extraordinary, non-recurring, one-time, unusual, etc.

Ordinarily, whenever there is a change in Index Shares, a change in a security, or a change to the price of a security due to spin-offs, rights issuances or special cash dividends, the Divisor is adjusted to ensure that there is no discontinuity in the value of the Underlying Index which might otherwise be caused by any such change. All changes are announced in advance and are reflected in the Underlying Index prior to market open on the Underlying Index effective date.

Index Rebalancing. The Underlying Index employs a modified market capitalization-weighting methodology. At each quarter, the Underlying Index is rebalanced such that the maximum weight of any security does not exceed 8% and no more than 5 securities are at that cap. The excess weight of any capped security is distributed proportionally across the remaining securities in the Underlying Index. If after redistribution, any of the five highest ranked securities in the Underlying Index are weighted below 8%, these securities are not capped. Next, any remaining securities in excess of 4% are capped at 4% and the excess weight is redistributed proportionally across the remaining securities in the Underlying Index. The process is repeated, if necessary, to derive the final weights.

The modified market capitalization-weighting methodology is applied to the capitalization of each security, using the Last Sale Price of the security at the close of trading on the last trading day in February, May, August and November. Index Shares are then calculated by multiplying the weight of the security derived above by the new market value of the Underlying Index and dividing the modified market capitalization for each security by its corresponding Last Sale Price. The changes are effective after trading on the third Friday in March, June, September and December.

In administering the Underlying Index, NASDAQ OMX may, from time to time, exercise reasonable discretion as it deems appropriate in order to ensure the integrity of the Underlying Index.

Index Availability. The Underlying Index is calculated continuously and widely disseminated to major data vendors.

¹ For purposes of this document, “Last Sale Price” refers to the following: For a security listed on NASDAQ, it is the last sale price on NASDAQ, which normally would be the Nasdaq Official Closing Price (“NOCP”) when NASDAQ is closed. For any NYSE-listed or NYSE MKT-listed security, it is the last regular way trade reported on such security’s primary U.S. listing market. If a security does not trade on its primary listing market on a given day, the most recent last sale price from the primary listing market (adjusted for corporate actions, if any) is used.

The Russell Indexes

•	stocks must trade at or above $1.00 on the last business day of August to be eligible for inclusion. If a stock in the index has a price lower than $1, it can remain in the index if the average price for the month is greater than $1;
•	for ranking and membership determination, all common share classes for a single company are combined to determine total market capitalization;
•	in cases where there are multiple common stock share classes and the share classes act independently of each other, each class is considered for inclusion separately; and
•	also excluded are preferred and convertible preferred stock, participating preferred stock, redeemable shares, warrants and rights, trust receipts, royalty trusts, limited liability issuers, OTC bulletin boards and pink sheet stocks, mutual funds, limited partnerships, and foreign stocks.

All eligible securities are sorted by decreasing total market capitalization to determine index eligibility.

Frank Russell Company uses a probability measure to assign stocks to the growth and value style indexes. The probability measure is used to indicate the degree of certainty that a stock is value or growth, based on three fundamental indicators: relative price-to-book (“PB”) ratio, Institutional Brokers’ Estimate System forecast medium-term growth (2 years) and sales per share historical growth (5 years). This method allows stocks to be represented as having both growth and value characteristics, while preserving the additive nature of the indexes. As a result, a stock may be a component of a Russell growth style index and also a component of the corresponding value style index, although the stock would likely have a different weight in each index.

Index Availability. The Russell indexes are calculated continuously and are available from major data vendors.

The S&P Indexes

Component Selection Criteria for Domestic Indexes. S&P Dow Jones Indices LLC’s (“SPDJI”) various Index Committees are responsible for the overall management of SPDJI's indices (“S&P DJI Indices”). Issuers (i.e., the “components”) selected for the S&P U.S. indexes represent a broad range of industry segments within the U.S. economy. The starting universe of publicly traded U.S. issuers classified by the Global Industry Classification Standard (GICS^®) is screened to eliminate ADRs, mutual funds, limited partnerships, royalty trusts, certain holding issuers, OTC bulletin board issues, pink sheet-listed issues, closed-end funds, ETFs and tracking stocks. REITs, except for mortgage REITs, are eligible for inclusion in the Indexes. The stock of each constituent must trade on either the NYSE, the NYSE Amex Equities or on NASDAQ. Additionally, only one share class per constituent will be included in an Index. The share class is selected by SPDJI and is generally defined as the largest, most liquid share class. Issuers with multiple share classes will have the classes combined for purposes of calculation of market capitalization. The following criteria are then analyzed to determine an issuer’s eligibility for inclusion in the S&P Indexes: (i)

ownership of an issuer’s outstanding common stock, in order to screen out closely held issuers; (ii) trading volume of an issuer’s shares, in order to ensure ample liquidity and efficient share pricing; and (iii) the financial and operating condition of an issuer.

The S&P DJI’s Indices are capitalization-weighted, based on the following formula: number of outstanding shares of a constituent (as determined by the float-adjusted market capitalization using SPDJI’s methodology) multiplied by the constituent’s share price. Issuers with float-adjusted market capitalizations below certain thresholds are not eligible for the Indexes. In addition, the market capitalization of an issuer eligible for inclusion typically must be greater than the Index’s minimum market capitalization at the time it is being considered for Index inclusion. The market capitalizations of an Index’s constituents are adjusted to reflect changes in capitalization resulting from mergers, acquisitions, stock rights, substitutions and other capital events. The market capitalizations of an Index’s constituent are adjusted for all strategic holdings, including private, corporate, and government holdings.

Component Selection Criteria for International Indexes. Stocks are eligible for the S&P Global Indices if they meet criteria for size, liquidity, profitability, and sector and market representation. Each of the S&P Global Indices is balanced across country and sector weights in the region/market. The S&P Global Indices begin with an eligible investable universe of stocks covering approximately 95% of each country’s total market capitalization. In some cases, the S&P Global Indexes may include ADRs and GDRs. Stocks with relatively small market capitalization or insufficient liquidity are excluded by SPDJI. To identify a candidate pool for index constituent selection, all stocks are carefully examined using a set of general criteria. The specific securities are then screened for industry sector classification; thus, the eligible securities are ranked according to GICS. Then, the Index components, now determined, are weighted on the basis of SPDJI’s float-adjusted, market capitalization methodology. Generally, SPDJI observes a prospective constituent’s liquidity over a period of at least six months before consideration for inclusion. However, there may be extraordinary situations when issuers should be added immediately (e.g., certain privatizations). When a particular issuer dominates its home market, it may be excluded from an Index if analysis of the sectors reveals that its securities are not as liquid as those of similar issuers in other countries. Once a year, the float adjustments will be reviewed and potentially changed based on such review. The values of an Index’s constituents are adjusted to reflect changes in capitalization resulting from mergers, acquisitions, stock rights, substitutions and other capital events. The market capitalization of index constituent issuers is adjusted for all strategic holdings, including private, corporate, and government holdings.

With respect to the non-U.S. components of the S&P Global Indexes, the eligible universe of index components that are considered for inclusion are from the following S&P DJI Indices: (i) the S&P/TSX 60 (Toronto Stock Exchange), which represents the liquid, large-cap stocks of the publicly listed issuers in the Canadian equities market; (ii) the S&P/TOPIX 150 (TSE) which represents the liquid, large-cap stocks of the publicly-listed issuers in the Japanese equities market; (iii) S&P/ASX All-Australian 50 Index (Australian Stock Exchange), which represents the liquid, large-cap stocks in the Australian equities market; (iv) the S&P Asia 50, which represents the liquid, large-cap stocks of four major equities markets in Asia (Hong Kong, South Korea, Taiwan and Singapore); (v) the S&P Latin America 40, which represents the liquid, large-cap stocks from major sectors of the Mexico, Brazil, Peru, Colombia and Chilé equity markets; and (vi) the S&P Europe 350, which represents the liquid, large-cap stocks of the publicly listed issuers in the region, covering approximately 70% of the region’s market capitalization.

Issue Changes. General oversight responsibility for the S&P DJI Indices, including overall policy guidelines and methodology, is handled by the S&P Global Index Committee. Maintenance of component investments, including additions and deletions to these investments, is the responsibility of separate regional index committees composed of S&P staff specialized in the various regional equity markets and, in some cases, with the assistance of local stock exchanges. Public announcements of index changes as the result of committee decisions will generally be made two business days in advance of the anticipated effective date whenever possible, although for exceptional corporate events announcements may be made earlier.

Index Maintenance. Maintaining the S&P DJI Indices includes monitoring and completing the adjustments for issuer additions and deletions, share changes, stock splits, stock dividends, and stock price adjustments due to restructuring and spin-offs. An issuer will be removed from the S&P DJI Indices as a result of mergers/acquisitions, bankruptcy, or restructuring. An issuer is removed from the relevant index as close as possible to the actual date on which the event occurred. An issuer can be removed from an index because it no longer meets current criteria for inclusion and/or is no longer representative of its industry group. All replacement issuers are selected based on the above component section criteria.

When calculating index weights, individual constituents’ shares held by governments, corporations, strategic partners, or other control groups are excluded from the issuer’s shares outstanding. Shares owned by other issuers are also excluded regardless of whether they are index constituents. In countries with regulated environments, where a foreign investment limit exists at the sector or issuer level, the constituent’s weight will reflect either the foreign investment limit or the percentage float, whichever is the more restrictive.

Each issuer’s financial statements will be used to update the major shareholders’ ownership. However, during the course of the year, SPDJI also monitors each issuer’s Investable Weight Factor (“IWF”) which is SPDJI’s term for the mathematical float factor used to calculate the float adjustment. If a change in IWF is caused by a major corporate action (i.e., privatization, merger, takeover, or share offering) and the change equal to or greater than 5%, a float adjustment will be implemented as soon as reasonably possible.

Changes in the number of shares outstanding driven by corporate events such as stock dividends, splits, and rights issues will be adjusted on the ex-date. Share changes of 5% or greater are implemented when they occur. Share changes of less than 5% are only updated on a quarterly basis on the Friday near the end of the calendar quarter. Generally, index changes due to rebalancing are announced two days before the effective date by way of a news release posted on www.us.spindices.com.

Index Availability. The S&P Indexes are calculated continuously and are available from major data vendors.

Exchange Rates. SPDJI uses the World Markets/Reuters Closing Spot Rates taken at 4:00 p.m. London time for the following funds: iShares Europe ETF, iShares Global 100 ETF, iShares Global Clean Energy ETF, iShares Global Consumer Discretionary ETF, iShares Global Consumer Staples ETF, iShares Global Energy ETF, iShares Global Financials ETF, iShares Global Industrials ETF, iShares Global Telecom ETF, iShares Global Utilities ETF, iShares North American Natural Resources ETF, iShares North American Tech ETF, iShares North American Tech-Multimedia Networking ETF and iShares North American Tech-Software ETF. Prior to January 31, 2013, SPDJI used the currency exchange (FX) rate corresponding to 5:15 p.m. Eastern time. In case World Markets/Reuters does not provide rates for specific markets on given days (for example, Christmas Day and New Year’s Day), the previous business day’s rates are normally used. SPDJI independently monitors the exchange rates on all its indexes. SPDJI may under exceptional circumstances elect to use alternative sources of exchange rates if the World Markets/Reuters rates are not available, or if SPDJI determines that the World Markets/Reuters rates are not reflective of market circumstances for a given currency on a particular day.

S&P International Preferred Stock Index^TM

Number of Components: approximately 113

Index Description. The S&P International Preferred Stock Index^TM measures the performance of a select group of preferred stocks trading on non-U.S. developed market exchanges, as defined by S&P. The preferred stocks included in the Underlying Index are selected by S&P using the methodology described below.

In general terms, the Underlying Index includes developed-market preferred stocks with a market capitalization of over $100 million that meet minimum price, liquidity, maturity and other requirements determined by S&P. S&P excludes from the Underlying Index: (i) preferred stocks which are structured products and brand-name products issued by financial institutions or are packaged securities linked to indexes, baskets of stocks or another company’s stock; (ii) preferred stocks that are issued by special ventures such as highway, airport, or dam operators; (iii) preferred stocks that have a mandatory conversion or scheduled maturity within the next 12 months; and (iv) trust preferred stocks. Once an issue of preferred stock is included in the Underlying Index, the removal criteria listed below are used to test its continuing eligibility as opposed to the exclusion factors listed above.

All additions to the Underlying Index are made on a quarterly rebalancing date, and there are no intra-quarter additions made to the Underlying Index. Inclusion in the Underlying Index is limited to issues whose indicated dividend yield is greater than or equal to 1% and less than or equal to 20%. In addition, for initial inclusion eligibility, each individual issue must be a preferred stock which has traded an average of 250,000 shares per month over the previous six months, as of the rebalancing reference date. Issues with fewer than six months of trading history are evaluated over the available period and may be included should size and available trading history infers the issue satisfies this requirement.

Preferred stocks are removed from the Underlying Index on a quarterly rebalancing date if they: (i) have an outstanding market capitalization of less than $100 million; (ii) have a six-month average monthly trading volume of less than 100,000 shares and have been a component of the Index for at least 12 months; or (iii) have an undetermined indicated dividend yield or an indicated dividend yield of less than 1% or greater than 20%.

Share changes for existing Underlying Index components occur semiannually in January and July. The data reference date for additions to and deletions from the Underlying Index is the last trading date of the month immediately preceding the rebalancing month. The Underlying Index is rebalanced on a quarterly basis; and changes are effective after the close of trading on the third Friday of January, April, July and October. The Underlying Index is calculated with a modified capitalization weighted scheme, with modifications being made to Underlying Index shares to prevent single stock concentration. There is no limit to the number of lines of a single company’s preferred stock is allowed in the Underlying Index; however, a maximum weight of 10% is set per issuer. All eligible lines for an issuer are included in the Underlying Index and capped on a pro rata basis to a maximum of 4% by issue of the Underlying Index market capitalization. For purposes of this limitation, S&P defines a single issuer to include companies that are under common control or are guaranteed by the same entity which is also affiliated with such companies. In the event the market capitalization weight of an issuer would exceed 10% or an issue would exceed 4% of the Underlying Index, all other stock weights in the Index are increased proportionately to account for such difference.

A constituent is removed intra-quarter if it is called or undergoes mandatory conversion or redemption. Subject to market conditions, S&P will provide clients with five-days advance notice of a deletion. Should an existing member of the Underlying

Index delist during the five-day notification period, it is removed at the closing price from its last day of trading. The quarterly rebalancing also results in deletions if constituents no longer meet continued eligibility requirements.

The index is rebalanced quarterly, with Underlying Index changes implemented after the close of trading on the third Fridays of January, April, July, and October.

Index Methodology. In general terms, the Underlying Index contains preferred stocks that meet minimum size, liquidity, exchange listing, maturity and other requirements determined by S&P. The Underlying Index may include preferred stocks that are issued in the U.S. by U.S-domiciled entities whose parent companies or guarantors may be non-U.S. entities. The Underlying Index is calculated with a modified capitalization weighted scheme, with modifications being made to Underlying Index shares to limit single issuer concentration.

There is no limit to the number of lines of a single company’s preferred stock allowed in the Underlying Index; however a maximum weight of 10% of index market capitalization is set per issuer with all eligible lines capped on a pro rata basis. For purposes of this limitation, S&P defines a single issuer to include companies that are under common control or are guaranteed by the event that fewer than 15 preferred issuers qualify based on the other Underlying Index criteria, the liquidity constraints below will be relaxed and the largest stocks included until the issuer count reaches 15. The Underlying Index is rebalanced quarterly, effective after the close of trading on the third Friday of January, April, July, and October. Share changes occur semi-annually at the January and July rebalances.

Component Selection Criteria. The Underlying Index excludes: (i) preferred stocks with a market capitalization of less than $100 million as of the rebalancing reference date; (ii) preferred stocks for which S&P cannot determine an indicated dividend yield; (iii) over-the-counter, bulletin board, and unregistered (144A) securities; (iv) preferred stocks that are structured products and brand-name products issued by financial institutions and that are packaged securities linked to indices, baskets of stocks or another company’s stock; and (v) preferred stocks that are issued by special ventures such as highway, airport, or dam operators. In addition, S&P applies the following inclusion and exclusion criteria. For preferred stocks that are not already in the Underlying Index, S&P may include: (i) issues that do not have a mandatory conversion or scheduled maturity within 12 months of the rebalancing date; and (ii) that have also traded an average of 250,000 shares per month over the previous six months. Issues with between one and six months of trading history will be evaluated over the available period and may be included should size and available trading history infer the issue will satisfy the volume requirement. For preferred stocks that have been in the Underlying Index for more than 12 months, S&P excludes issues that have not traded

an average of 125,000 shares per month over the previous six months as of the rebalancing reference date. The reference date for additions and deletions is the last trading date of the month immediately preceding the rebalancing month. Additions occur only at the quarterly rebalancing. Deletions occur at the quarterly rebalancing based on the above eligibility criteria, but may also occur intra-quarter due to mandatory conversions, redemptions, or delistings.

Investment Restrictions

The Board has adopted as fundamental policies the following numbered investment restrictions, which cannot be changed without the approval of the holders of a majority of the applicable Fund’s outstanding voting securities. A vote of a majority of the outstanding voting securities of a Fund is defined in the 1940 Act as the lesser of (i) 67% or more of the voting securities present at a shareholder meeting, if the holders of more than 50% of the outstanding voting securities of the Fund are present or represented by proxy, or (ii) more than 50% of outstanding voting securities of the Fund. Each Fund has also adopted certain non-fundamental investment policies, including its investment objective. Non-fundamental investment

policies may be changed by the Board without shareholder approval. Therefore, each Fund may change its investment objective and its Underlying Index without shareholder approval.

Notations Regarding the iShares Russell 1000 Pure U.S. Revenue ETF's and iShares U.S. Infrastructure ETF's Fundamental Investment Restrictions

The following notations are not considered to be part of each Fund's fundamental investment restrictions and are subject to change without shareholder approval.

With respect to the fundamental policy relating to concentration set forth in (1) above, the Investment Company Act does not define what constitutes “concentration” in an industry. The SEC staff has taken the position that investment of 25% or more of a fund’s total assets in one or more issuers conducting their principal activities in the same industry or group of industries constitutes concentration. It is possible that interpretations of concentration could change in the future. The policy in (1) above will be interpreted to refer to concentration as that term may be interpreted from time to time. The policy also will be interpreted to permit investment without limit in the following: securities of the U.S. government and its agencies or instrumentalities; securities of state, territory, possession or municipal governments and their authorities, agencies, instrumentalities or political subdivisions; and repurchase agreements collateralized by any such obligations. Accordingly, issuers of the foregoing securities will not be considered to be members of any industry. There also will be no limit on investment in issuers domiciled in a single jurisdiction or country. Finance companies will be considered to be in the industries of their parents if their activities are primarily related to financing the activities of the parents. Each foreign government will be considered to be a member of a separate industry. With respect to a Fund's industry classifications, each Fund currently utilizes any one or more of the industry sub-classifications used by one or more widely recognized market indexes or rating group indexes, and/or as defined by Fund management. The policy also will be interpreted to give broad authority to a Fund as to how to classify issuers within or among industries.

and to borrow up to 5% of the Fund’s total assets from banks or other lenders for temporary purposes. (The Fund’s total assets include the amounts being borrowed.) To limit the risks attendant to borrowing, the Investment Company Act requires each Fund to maintain at all times an “asset coverage” of at least 300% of the amount of its borrowings. Asset coverage means the ratio that the value of each Fund's total assets (including amounts borrowed), minus liabilities other than borrowings, bears to the aggregate amount of all borrowings. Borrowing money to increase portfolio holdings is known as “leveraging.” Certain trading practices and investments, such as reverse repurchase agreements, may be considered to be borrowings or involve leverage and thus are subject to the Investment Company Act restrictions. In accordance with SEC staff guidance interpretations, when a Fund engages in such transactions, the Fund instead of maintaining asset coverage of at least 300%, may segregate or earmark liquid assets, or enter into an offsetting position, in an amount at least equal to the Fund’s exposure, on a mark-to-market basis, to the transaction (as calculated pursuant to requirements of the SEC). The policy in (2) above will be interpreted to permit each Fund to engage in trading practices and investments that may be considered to be borrowing or to involve leverage to the extent permitted by the Investment Company Act and to permit each Fund to segregate or earmark liquid assets or enter into offsetting positions in accordance with the Investment Company Act. Short-term credits necessary for the settlement of securities transactions and arrangements with respect to securities lending will not be considered to be borrowings under the policy. Practices and investments that may involve leverage but are not considered to be borrowings are not subject to the policy.

With respect to the fundamental policy relating to underwriting set forth in (5) above, the Investment Company Act does not prohibit each Fund from engaging in the underwriting business or from underwriting the securities of other issuers; in fact, in the case of diversified funds, the Investment Company Act permits the Fund to have underwriting commitments of up to 25% of its assets under certain circumstances. Those circumstances currently are that the amount of each Fund's underwriting commitments, when added to the value of the Fund’s investments in issuers where each Fund owns more than 10% of the outstanding voting securities of those issuers, cannot exceed the 25% cap. A fund engaging in transactions involving the acquisition or disposition of portfolio securities may be considered to be an underwriter under the 1933 Act. Although it is not believed that the application of the 1933 Act provisions described above would cause a Fund to be engaged in the business of underwriting, the policy in (5) above will be interpreted not to prevent the Fund from engaging in transactions involving the acquisition or disposition of portfolio securities, regardless of whether the Fund may be considered to be an underwriter under the 1933 Act or is otherwise engaged in the underwriting business to the extent permitted by applicable law.

Non-Fundamental Investment Policies

iShares Russell 1000 Pure U.S. Revenue ETF and iShares U.S. Infrastructure ETF Only

Each Fund has adopted a non-fundamental policy not to make short sales of securities or maintain a short position, except to the extent permitted by each Fund’s Prospectus and SAI, as amended from time to time, and applicable law.

Unless otherwise indicated, all limitations under each Fund's fundamental or non-fundamental investment restrictions apply only at the time that a transaction is undertaken. Any change in the percentage of each Fund's assets invested in certain securities or other instruments resulting from market fluctuations or other changes in each Fund’s total assets will not require each Fund to dispose of an investment until BFA determines that it is practicable to sell or close out the investment without undue market or tax consequences.

All Funds Other Than the iShares Russell 1000 Pure U.S. Revenue ETF and iShares U.S. Infrastructure ETF

Each Fund has adopted a non-fundamental policy not to invest in the securities of a company for the purpose of exercising management or control, or purchase or otherwise acquire any illiquid security, except as permitted under the 1940 Act, which currently permits up to 15% of each Fund’s net assets to be invested in illiquid securities (calculated at the time of investment).

BFA monitors the liquidity of restricted securities in each Fund's portfolio. In reaching liquidity decisions, BFA considers the following factors:

•	The frequency of trades and quotes for the security;
•	The number of dealers wishing to purchase or sell the security and the number of other potential purchasers;
•	Dealer undertakings to make a market in the security; and
•	The nature of the security and the nature of the marketplace in which it trades (e.g., the time needed to dispose of the security, the method of soliciting offers and the mechanics of transfer).

If any percentage restriction described above is complied with at the time of an investment, a later increase or decrease in percentage resulting from a change in values of assets will not constitute a violation of such restriction, except that certain percentage limitations will be observed continuously in accordance with applicable law.

All Funds

Each Fund has adopted a non-fundamental investment policy in accordance with Rule 35d-1 under the 1940 Act to invest, under normal circumstances, at least 80% of the value of its net assets, plus the amount of any borrowings for investment purposes, for all Funds other than the iShares U.S. Infrastructure ETF, in component securities of the Underlying Index or in depositary receipts representing component securities in the Underlying Index, and for the iShares U.S. Infrastructure ETF, in component securities of its Underlying Index. Each Fund also has adopted a policy to provide its shareholders with at least 60 days’ prior written notice of any change in such policy. If, subsequent to an investment, the 80% requirement is no longer met, a Fund’s future investments will be made in a manner that will bring the Fund into compliance with this policy.

Each Fund has adopted a non-fundamental limitation such that, under normal market conditions, any borrowings by the Fund will not exceed 10% of the Fund's net assets.

Continuous Offering

Broker-dealer firms should also note that dealers who are not “underwriters” but are effecting transactions in shares, whether or not participating in the distribution of shares, generally are required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(a)(3) of the 1933 Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. Firms that incur a prospectus delivery obligation with respect to shares of the Funds are reminded that, pursuant to Rule 153 under the 1933 Act, a prospectus delivery obligation under Section 5(b)(2) of the 1933 Act owed to an exchange member in connection with a sale on the Listing Exchange generally is satisfied by the fact that the prospectus is available at the Listing Exchange upon request. The prospectus delivery mechanism provided in Rule 153 is available only with respect to transactions on an exchange.

Management

The registered investment companies advised by BFA or its affiliates (the “BlackRock-advised Funds”) are organized into one complex of closed-end funds, two complexes of open-end funds and one complex of ETFs (“Exchange-Traded Fund Complex”) (each, a “BlackRock Fund Complex”). Each Fund is included in the BlackRock Fund Complex referred to as the Exchange-Traded Fund Complex. Each Trustee also serves as a Director of iShares, Inc. and a Trustee of iShares U.S. ETF Trust and, as a result, oversees all of the funds within the Exchange-Traded Fund Complex, which consists of 358 funds as of August 1, 2018. Drew E. Lawton, from October 2016 to June 2017, and Richard L. Fagnani, from April 2017 to June 2017, served as members of the advisory board (“Advisory Board,” members of which are “Advisory Board Members”) for the Trust, iShares, Inc. and iShares U.S. ETF Trust with respect to all funds within the Exchange-Traded Fund Complex. With the exception of Robert S. Kapito, Mark K. Wiedman, Charles Park, Martin Small and Benjamin Archibald, the address of each Trustee and officer is c/o BlackRock, Inc., 400 Howard Street, San Francisco, CA 94105. The address of Mr. Kapito, Mr. Wiedman, Mr. Park, Mr. Small and Mr. Archibald is c/o BlackRock, Inc., Park Avenue Plaza, 55 East 52^nd Street, New York, NY 10055. The Board has designated Cecilia H. Herbert as its Independent Board Chair. Additional information about the Funds' Trustees and officers may be found in this SAI, which is available without charge, upon request, by calling toll-free 1-800-iShares (1-800-474-2737).

The Board has concluded that, based on each Trustee’s experience, qualifications, attributes or skills on an individual basis and in combination with those of the other Trustees, each Trustee should serve as a Trustee of the Board. Among the attributes common to all Trustees are their ability to review critically, evaluate, question and discuss information provided to them, to interact effectively with the Funds' investment adviser, other service providers, counsel and the independent registered public accounting firm, and to exercise effective business judgment in the performance of their duties as Trustees. A Trustee’s ability to perform his or her duties effectively may have been attained through the Trustee’s educational background or professional training; business, consulting, public service or academic positions; experience from service as a Board member of the Funds and the other funds in the Trust (and any predecessor funds), other investment funds, public companies, or non-profit entities or other organizations; and/or other life experiences. Also, set forth below is a brief discussion of the specific experience, qualifications, attributes or skills of each Trustee that led the Board to conclude that he or she should serve (or continue to serve) as a Trustee.

Board – Leadership Structure and Oversight Responsibilities

The Board has appointed an Independent Trustee to serve in the role of Board Chair. The Board Chair’s role is to preside at all meetings of the Board and to act as a liaison with service providers, officers, attorneys, and other Trustees generally between meetings. The Board Chair may also perform such other functions as may be delegated by the Board from time to time. The Board has established seven standing Committees: a Nominating and Governance Committee, an Audit Committee, a 15(c) Committee, a Securities Lending Committee, a Risk Committee, an Equity Plus Committee and a Fixed Income Plus Committee to assist the Board in the oversight and direction of the business and affairs of the Funds, and from time to time the Board may establish ad hoc committees or informal working groups to review and address the policies and practices of the Funds with respect to certain specified matters. The Chair of each standing Committee is an Independent Trustee. The role of the Chair of each Committee is to preside at all meetings of the Committee and to act as a liaison with service providers, officers, attorneys and other Trustees between meetings. Each standing Committee meets regularly to conduct the oversight functions delegated to the Committee by the Board and reports its finding to the Board. The Board and each standing Committee conduct annual assessments of their oversight function and structure. The Board has determined that the Board’s leadership structure is appropriate because it allows the Board to exercise independent judgment over management and it allocates areas of responsibility among committees of Independent Trustees and the full Board to enhance effective oversight.

The members of the Risk Committee are Jane D. Carlin (Chair), Charles A. Hurty, Drew E. Lawton and John E. Martinez, each of whom is an Independent Trustee. The principal responsibility of the Risk Committee is to consider and organize on behalf of the Board risk related matters of the Funds so the Board may most effectively structure itself to oversee them. The Risk Committee commenced on January 1, 2016. The Risk Committee met five times during the fiscal year ended March 31, 2018.

As the Chair of the Board, Cecilia H. Herbert may serve as an ex-officio member of each Committee.

BlackRock is one of the world's largest asset management firms. PNC is a diversified financial services organization spanning the retail, business and corporate markets. BlackRock, PNC and their respective affiliates (including, for these purposes, their directors, partners, trustees, managing members, officers and employees), including the entities and personnel who may be involved in the investment activities and business operations of a Fund, are engaged worldwide in businesses, including managing equities, fixed-income securities, cash and alternative investments, and banking and other financial services, and have interests other than that of managing a Fund. These are considerations of which investors in a Fund should be aware, and which may cause conflicts of interest that could disadvantage a Fund and its shareholders. These businesses and interests include potential multiple advisory, transactional, financial and other relationships with, or interests in, companies and interests in securities or other instruments that may be purchased or sold by a Fund.

BlackRock and the other Affiliates have proprietary interests in, and may manage or advise with respect to, accounts or funds (including separate accounts and other funds and collective investment vehicles) that have investment objectives similar to those of a Fund and/or that engage in transactions in the same types of securities, currencies and instruments as a Fund. One or more Affiliates are also major participants in the global currency, equities, swap and fixed-income markets, in each case, for the accounts of customers and, in some cases, on a proprietary basis. As such, one or more Affiliates are or may be actively engaged in transactions in the same securities, currencies, and instruments in which a Fund invests. Such activities could affect the prices and availability of the securities, currencies, and instruments in which a Fund invests, which could have an adverse impact on a Fund's performance. Such transactions, particularly in respect of most proprietary accounts or client accounts, will be executed independently of a Fund's transactions and thus at prices or rates that may be more or less favorable than those obtained by a Fund.

105

Fund to be unable to engage in certain activities, including purchasing or disposing of securities, when it might otherwise be desirable for it to do so.

106

At times, these activities may cause departments of BlackRock or the other Affiliates to give advice to clients that may cause these clients to take actions adverse to the interests of a Fund. To the extent affiliated transactions are permitted, a Fund will deal with BlackRock and the other Affiliates (except with respect to BFA or affiliated sub-advisers of a Fund, as applicable) on an arms-length basis.

Subject to applicable law, the Affiliates (and their personnel and other distributors) will be entitled to retain fees and other amounts that they receive in connection with their service to the Funds as broker, dealer, agent, lender, adviser or in other commercial capacities. No accounting to a Fund or its shareholders will be required, and no fees or other compensation payable by a Fund or its shareholders will be reduced by reason of receipt by an Affiliate of any such fees or other amounts.

Lending on behalf of a Fund is done by BTC pursuant to SEC exemptive relief, enabling BTC to act as securities lending agent to, and receive a share of securities lending revenues from, the Fund. An Affiliate will also receive compensation for managing the reinvestment of the cash collateral from securities lending. There are potential conflicts of interest in managing a securities lending program, including but not limited to: (i) BTC as securities lending agent may have an incentive to increase or decrease the amount of securities on loan or to lend particular securities in order to generate additional risk-adjusted revenue for BTC and its affiliates; and (ii) BTC as securities lending agent may have an incentive to allocate loans to clients that would provide more revenue to BlackRock. As described further below, BlackRock seeks to mitigate this conflict by providing its securities lending clients with equal lending opportunities over time in order to approximate pro-rata allocation.

107

management of the indemnification exposure limit may affect the amount of securities lending activity BlackRock may conduct at any given point in time and impact indemnified and non-indemnified clients by reducing the volume of lending opportunities for certain loans (including by asset type, collateral type and/or revenue profile).

Prevailing trading activity frequently may make impossible the receipt of the same price or execution on the entire volume of securities purchased or sold. When this occurs, the various prices may be averaged, and the Funds will be charged or credited with the average price. Thus, the effect of the aggregation may operate on some occasions to the disadvantage of the Funds. In addition, under certain circumstances, the Funds will not be charged the same commission or commission equivalent rates in connection with a bunched or aggregated order.

108

portion of the commissions or commission credits to another firm that provides research to BlackRock. To the extent that BlackRock engages in commission sharing arrangements, many of the same conflicts related to traditional soft dollars may exist.

BlackRock may utilize certain electronic crossing networks (“ECNs”) (including, without limitation, ECNs in which BlackRock or the other Affiliates have an investment or other interest, to the extent permitted by applicable law) in executing client securities transactions for certain types of securities. These ECNs may charge fees for their services, including access fees and transaction fees. The transaction fees, which are similar to commissions or markups/markdowns, will generally be charged to clients and, like commissions and markups/markdowns, would generally be included in the cost of the securities purchased. Access fees may be paid by BlackRock even though incurred in connection with executing transactions on behalf of clients, including the Funds. In certain circumstances, ECNs may offer volume discounts that will reduce the access fees typically paid by BlackRock. BlackRock will only utilize ECNs consistent with its obligation to seek to obtain best execution in client transactions.

BlackRock has adopted policies and procedures designed to prevent conflicts of interest from influencing proxy voting decisions that it makes on behalf of advisory clients, including the Funds, and to help ensure that such decisions are made in accordance with BlackRock's fiduciary obligations to its clients. Nevertheless, notwithstanding such proxy voting policies and procedures, actual proxy voting decisions of BlackRock may have the effect of favoring the interests of other clients or businesses of other divisions or units of BlackRock and/or the other Affiliates, provided that BlackRock believes such voting decisions to be in accordance with its fiduciary obligations. For a more detailed discussion of these policies and procedures, see the Proxy Voting Policy section of this SAI.

It is also possible that, from time to time, BlackRock or the other Affiliates may, subject to compliance with applicable law, purchase and hold shares of a Fund. Increasing a Fund’s assets may enhance liquidity, investment flexibility and diversification and may contribute to economies of scale that tend to reduce the Fund's expense ratio. BlackRock and the other Affiliates reserve the right, subject to compliance with applicable law, to sell into the market or redeem in Creation Units through an Authorized Participant at any time some or all of the shares of a Fund acquired for their own accounts. A large sale or redemption of shares of a Fund by BlackRock or the other Affiliates could significantly reduce the asset size of the Fund, which might have an adverse effect on the Fund's liquidity, investment flexibility, portfolio diversification, expense ratio or ability to comply with the listing requirements for the Fund. BlackRock seeks to consider the effect of redemptions on a Fund and other shareholders in deciding whether to redeem its shares but is not obligated to do so and may elect not to do so.

109

to services to and sales of a Fund or other products may be greater than remuneration and profitability relating to services to and sales of certain funds or other products that might be provided or offered. BlackRock and the other Affiliates and their sales personnel may directly or indirectly receive a portion of the fees and commissions charged to a Fund or its shareholders. BlackRock and its advisory or other personnel may also benefit from increased amounts of assets under management. Fees and commissions may also be higher than for other products or services, and the remuneration and profitability to BlackRock or the other Affiliates and such personnel resulting from transactions on behalf of or management of a Fund may be greater than the remuneration and profitability resulting from other funds or products.

BlackRock and the other Affiliates may provide valuation assistance to certain clients with respect to certain securities or other investments and the valuation recommendations made for their clients' accounts may differ from the valuations for the same securities or investments assigned by a Fund's pricing vendors, especially if such valuations are based on broker-dealer quotes or other data sources unavailable to the Fund's pricing vendors. While BlackRock will generally communicate its valuation information or determinations to a Fund's pricing vendors and/or fund accountants, there may be instances where the Fund's pricing vendors or fund accountants assign a different valuation to a security or other investment than the valuation for such security or investment determined or recommended by BlackRock.

110

personal accounts of investment professionals and others who normally come into possession of information regarding a Fund's portfolio transactions. Each code of ethics is available by contacting BlackRock or by accessing the EDGAR Database on the SEC's Internet site at http://www.sec.gov, and copies may be obtained, after paying a duplicating fee, by e-mail at publicinfo@sec.gov or by writing the SEC's Public Reference Room, Washington, DC 20549-1520. Information about accessing documents on the SEC’s website may be obtained by calling the SEC at (800) SEC-0330.

BlackRock and the other Affiliates will not purchase securities or other property from, or sell securities or other property to, a Fund, except that a Fund may in accordance with rules or guidance adopted under the 1940 Act engage in transactions with accounts that are affiliated with a Fund as a result of common officers, directors, or investment advisers or pursuant to exemptive orders granted to the Funds and/or BlackRock by the SEC. These transactions would be effected in circumstances in which BlackRock determined that it would be appropriate for a Fund to purchase and another client of BlackRock to sell, or a Fund to sell and another client of BlackRock to purchase, the same security or instrument on the same day. From time to time, the activities of a Fund may be restricted because of regulatory requirements applicable to BlackRock or the other Affiliates and/or BlackRock's internal policies designed to comply with, limit the applicability of, or otherwise relate to such requirements. A client not advised by BlackRock would not be subject to some of those considerations. There may be periods when BlackRock may not initiate or recommend certain types of transactions, or may otherwise restrict or limit their advice in certain securities or instruments issued by or related to companies for which an Affiliate is performing investment banking, market making, advisory or other services or has proprietary positions. For example, when an Affiliate is engaged in an underwriting or other distribution of securities of, or advisory services for, a company, the Funds may be prohibited from or limited in purchasing or selling securities of that company. In addition, when BlackRock provides advisory or risk management services for a company, BlackRock may be prohibited from or limited in purchasing or selling securities of that company on behalf of a Fund, particularly where such services result in BlackRock obtaining material non-public information about the company (e.g., in connection with participation in a creditors’ committee). Similar situations could arise if personnel of BlackRock or the other Affiliates serve as directors of companies the securities of which a Fund wishes to purchase or sell. However, if permitted by applicable law, and where consistent with BlackRock’s policies and procedures (including the necessary implementation of appropriate information barriers), the Funds may purchase securities or instruments that are issued by such companies, are the subject of an underwriting, distribution or advisory assignment by an Affiliate, or are the subject of an advisory or risk management assignment by BlackRock, or where personnel of BlackRock or the other Affiliates are directors or officers of the issuer.

In those circumstances where ownership thresholds or limitations must be observed, BlackRock seeks to allocate limited investment opportunities equitably among clients (including the Funds), taking into consideration benchmark weight and investment strategy. BlackRock has adopted certain controls designed to prevent the occurrence of a breach of any applicable ownership threshold or limits, including, for example, when ownership in certain securities nears an applicable threshold, BlackRock may remove such securities from the list of Deposit Securities to be delivered to the Fund in connection with purchases of Creation Units of such Fund and may limit purchases in such securities to the issuer's weighting in the applicable benchmark used by BlackRock to manage such Fund. If client (including Fund) holdings of an issuer exceed an applicable threshold and BlackRock is unable to obtain relief to enable the continued holding of such investments, it may be

111

necessary to sell down these positions to meet the applicable limitations. In these cases, benchmark overweight positions will be sold prior to benchmark positions being reduced to meet applicable limitations.

BlackRock and the other Affiliates may not serve as Authorized Participants in the creation and redemption of iShares ETFs, but may serve as authorized participants of third-party ETFs.

BlackRock or the other Affiliates own or have an ownership interest in certain trading, portfolio management, operations and/or information systems used by Fund service providers. These systems are, or will be, used by a Fund service provider in connection with the provision of services to accounts managed by BlackRock and funds managed and sponsored by BlackRock, including the Funds, that engage the service provider (typically the custodian). A Fund’s service provider remunerates BlackRock or the other Affiliates for the use of the systems. A Fund service provider’s payments to BlackRock or the other Affiliates for the use of these systems may enhance the profitability of BlackRock and the other Affiliates. BlackRock’s or the other Affiliates’ receipt of fees from a service provider in connection with the use of systems provided by BlackRock or the other Affiliates may create an incentive for BlackRock to recommend that a Fund enter into or renew an arrangement with the service provider.

Present and future activities of BlackRock and the other Affiliates, including BFA, in addition to those described in this section, may give rise to additional conflicts of interest.

Investment Advisory, Administrative and Distribution Services

Pursuant to the investment advisory agreement, BFA may, from time to time, in its sole discretion and to the extent permitted by applicable law, appoint one or more sub-advisers, including, without limitation, affiliates of BFA, to perform investment advisory or other services with respect to a Fund. In addition, BFA may delegate certain of its investment advisory functions under the investment advisory agreement to one or more of its affiliates to the extent permitted by applicable law. BFA may terminate any or all sub-advisers or such delegation arrangements in its sole discretion upon appropriate notice at any time to the extent permitted by applicable law.

Investment Sub-Adviser. Pursuant to the Investment Advisory Agreement between BFA and the Trust entered into on behalf of the iShares International Preferred Stock ETF, BFA may from time to time, in its sole discretion, to the extent permitted by applicable law, appoint one or more sub-advisers, including, without limitation, affiliates of BFA, to perform investment advisory services with respect to the Fund. In addition, BFA may delegate certain of its investment advisory functions under the Investment Advisory Agreement to one or more of its affiliates to the extent permitted by applicable law. BFA may terminate any or all sub-advisers or such delegation arrangements in its sole discretion at any time to the extent permitted by applicable law.

BFA has entered into an investment sub-advisory agreement (the “Sub-Advisory Agreement” and together with the Investment Advisory Agreement, the “Advisory Agreements”) with the Sub-Adviser. The Sub-Adviser is an investment adviser located in the U.K. The Sub-Adviser is an affiliate of BFA and is a registered investment adviser and a commodity pool operator organized in 1999. As of June 30, 2018, the Sub-Adviser’s total assets under management were approximately $16.40 billion.

Under the Sub-Advisory Agreement, subject to the supervision and oversight of the Board and BFA, the Sub-Adviser will be primarily responsible for execution of securities transactions outside the U.S. and Canada and may, from time to time, participate in the management of specified assets in the Fund’s portfolio.

Pursuant to the Sub-Advisory Agreement, BFA pays the Sub-Adviser for services it provides either: (i) a fee equal to a percentage of the management fee paid to BFA under the Investment Advisory Agreement, or (ii) an amount based on the cost of the services provided. If the Sub-Adviser provides services related to both portfolio management and trading it is entitled to receive, from BFA, an amount equal to 20% of BFA’s management fee, and if the Sub-Adviser provides services

117

related solely to trading then it is entitled to receive, from BFA, an amount equal to 110% of the actual pre-tax costs incurred by the Sub-Adviser. The Sub-Adviser may be responsible for the day-to-day management of the Fund or portions of the Fund.

Unless earlier terminated as described below, each Advisory Agreement will remain in effect for an initial two year period and from year to year if approved annually (i) by the Board or by a vote of a majority of the outstanding voting securities of the Fund, and (ii) by a majority of the Trustees who are not parties to such agreement or interested persons (as defined in the 1940 Act) of any such party.

Each Advisory Agreement with respect to each Fund is terminable without penalty, on 60 days' notice, by the Board or by a vote of the holders of a majority of the applicable Fund’s outstanding voting securities (as defined in the 1940 Act). The Investment Advisory Agreement is also terminable upon 60 days' notice by BFA. The Sub-Advisory Agreement is also terminable on 60 days' written notice at the option of either BFA or the Sub-Adviser. Each Advisory Agreement will terminate automatically in the event of its assignment (as defined in the 1940 Act).

Portfolio Managers. As of March 31, 2018, the individuals named as Portfolio Managers in the Funds' Prospectuses were also primarily responsible for the day-to-day management of other iShares funds and certain other types of portfolios and/or accounts as follows:

Each of the portfolios or accounts for which the Portfolio Managers are primarily responsible for the day-to-day management seeks to track the rate of return, risk profile and other characteristics of independent third-party indexes by either replicating the same combination of securities and other financial instruments that constitute those indexes or through a representative sampling of the securities and other financial instruments that constitute those indexes based on objective criteria and data. Pursuant to BFA’s policy, investment opportunities are allocated equitably among the Funds and other portfolios and accounts. For example, under certain circumstances, an investment opportunity may be restricted due to limited supply in the market, legal constraints or other factors, in which event the investment opportunity will be allocated equitably among those portfolios and accounts, including the Funds, seeking such investment opportunity. As a consequence, from time to time each Fund may receive a smaller allocation of an investment opportunity than they would have if the Portfolio Managers and BFA and its affiliates did not manage other portfolios or accounts.

Like the Funds, the other portfolios or accounts for which the Portfolio Managers are primarily responsible for the day-to-day portfolio management generally pay an asset-based fee to BFA or its affiliates, as applicable, for its advisory services. One or more of those other portfolios or accounts, however, may pay BFA or its affiliates a performance-based fee in lieu of, or in addition to, an asset-based fee for its advisory services. A portfolio or account with a performance-based fee would pay BFA or its affiliates a portion of that portfolio’s or account’s gains, or would pay BFA or its affiliates more for its services than would otherwise be the case if BFA or any of its affiliates meets or exceeds specified performance targets. Performance-based fee arrangements could present an incentive for BFA or its affiliates to devote greater resources, and allocate more investment opportunities, to the portfolios or accounts that have those fee arrangements, relative to other portfolios or accounts, in order to earn larger fees. Although BFA and each of its affiliates have an obligation to allocate resources and opportunities equitably among portfolios and accounts and intend to do so, shareholders of the Funds should be aware that, as with any group of portfolios and accounts managed by an investment adviser and/or its affiliates pursuant to varying fee arrangements, including performance-based fee arrangements, there is the potential for a conflict of interest, which may result in the Portfolio Managers favoring those portfolios or accounts with performance-based fee arrangements.

The discussion below describes the Portfolio Managers' compensation as of March 31, 2018.

Portfolio Manager Compensation Overview

Base compensation. Generally, portfolio managers receive base compensation based on their position with the firm.

120

Other Compensation Benefits. In addition to base compensation and discretionary incentive compensation, portfolio managers may be eligible to receive or participate in one or more of the following:

Incentive Savings Plans — BlackRock, Inc. has created a variety of incentive savings plans in which BlackRock, Inc. employees are eligible to participate, including a 401(k) plan, the BlackRock Retirement Savings Plan (“RSP”), and the BlackRock Employee Stock Purchase Plan (“ESPP”). The employer contribution components of the RSP include a company match equal to 50% of the first 8% of eligible pay contributed to the plan capped at $5,000 per year, and a company retirement contribution equal to 3-5% of eligible compensation up to the U.S. Internal Revenue Service (the “IRS”) limit ($275,000 for 2018). The RSP offers a range of investment options, including registered investment companies and collective investment funds managed by the firm. BlackRock, Inc. contributions follow the investment direction set by participants for their own contributions or, absent participant investment direction, are invested into an index target date fund that corresponds to, or is closest to, the year in which the participant attains age 65. The ESPP allows for investment in BlackRock, Inc. common stock at a 5% discount on the fair market value of the stock on the purchase date. Annual participation in the ESPP is limited to the purchase of 1,000 shares of common stock or a dollar value of $25,000 based on its fair market value on the Purchase Date. Rachel Aguirre, Diane Hsiung, Jennifer Hsui, Alan Mason, Greg Savage and Amy Whitelaw are each eligible to participate in these plans.

As of March 31, 2018, the Portfolio Managers beneficially owned shares of the Funds, for which they are primarily responsible for the day-to-day management, in the amounts reflected in the following tables:

Each Fund retains a portion of the securities lending income and remits the remaining portion to BTC as compensation for its services as securities lending agent. Securities lending income is generally equal to the total of income earned from the reinvestment of cash collateral (and excludes collateral investment fees as defined below), and any fees or other payments to and from borrowers of securities. As securities lending agent, BTC bears all operational costs directly related to securities lending. Each Fund is responsible for fees in connection with the investment of cash collateral received for securities on loan in a money market fund managed by BFA (the “collateral investment fees”); however, BTC has agreed to reduce the amount of securities lending income it receives in order to effectively limit the collateral investment fees a Fund bears to an annual rate of 0.04%. Such money market fund shares will not be subject to a sales load, redemption fee, distribution fee or service fee.

Pursuant to the Securities Lending Agency Agreement:

(i) All Funds except for the iShares Europe ETF, iShares Global 100 ETF, iShares Global Clean Energy ETF, iShares Global Consumer Discretionary ETF, iShares Global Consumer Staples ETF, iShares Global Energy ETF, iShares Global Financials ETF, iShares Global Healthcare ETF, iShares Global Industrials ETF, iShares Global Infrastructure ETF, iShares Global Telecom ETF, iShares Global Utilities ETF, iShares International Developed Property ETF, iShares International Preferred Stock ETF and iShares JPX-Nikkei 400 ETF (“Domestic Equity Funds”) retain 71.5% of securities lending income (which excludes collateral investment fees) and (ii) this amount can never be less than 65% of the sum of securities lending income plus collateral investment fees.

(i) The iShares Europe ETF, iShares Global 100 ETF, iShares Global Clean Energy ETF, iShares Global Consumer Discretionary ETF, iShares Global Consumer Staples ETF, iShares Global Energy ETF, iShares Global Financials ETF, iShares Global Healthcare ETF, iShares Global Industrials ETF, iShares Global Infrastructure ETF, iShares Global Telecom ETF, iShares Global Utilities ETF, iShares International Developed Property ETF, iShares International Preferred Stock ETF and iShares JPX-Nikkei 400 ETF (“International Equity Funds”) retain 80% of securities lending income (which excludes collateral investment fees) and (ii) this amount can never be less than 70% of the sum of securities lending income plus collateral investment fees.

In addition, commencing the business day following the date that the aggregate securities lending income (which includes, for this purpose, collateral investment fees) earned across the Exchange-Traded Fund Complex (as defined under “Management—Trustees and Officers”) in a calendar year exceeds the aggregate securities lending income earned across the Exchange-Traded Fund Complex in calendar year 2013 (the Hurdle Date), each applicable Fund, pursuant to the securities lending agreement, will receive for the remainder of that calendar year securities lending income as follows:

Domestic Equity Funds

International Equity Funds

The services provided to the Funds by BTC in the most recent fiscal year ended March 31, 2018 primarily included the following:

134

(1) selecting borrowers from an approved list of borrowers and executing a securities lending agreement as agent on behalf of the Funds with each such borrower;

(2) negotiating the terms of securities loans, including the amount of fees;

(3) directing the delivery of loaned securities;

(4) monitoring the daily value of the loaned securities and directing the payment of additional collateral or the return of excess collateral, as necessary;

(5) investing cash collateral received in connection with any loaned securities;

(6) monitoring distributions on loaned securities (for example, interest and dividend activity);

(8) terminating securities loans and arranging for the return of loaned securities to the Funds at loan termination.

The following tables show the dollar amounts of income and fees/compensation related to the securities lending activities of each Fund during its most recent fiscal year ended March 31, 2018.

For the iShares U.S. Infrastructure ETF, because the inception date of the Fund is April 3, 2018, no services have been provided by BTC as the Fund’s securities lending agent, and the Fund had no income and fees/compensation related to its securities lending activities for the fiscal year ended March 31, 2018.

Payments by BFA and its Affiliates. BFA and/or its affiliates (“BFA Entities”) may pay certain broker-dealers, registered investment advisers, banks and other financial intermediaries (“Intermediaries”) for certain activities related to the Funds, other iShares funds or exchange-traded products in general. BFA Entities make these payments from their own assets and not from the assets of the Funds. Although a portion of BFA Entities’ revenue comes directly or indirectly in part from fees paid by the Funds, other iShares funds or exchange-traded products, these payments do not increase the price paid by investors for the purchase of shares of, or the cost of owning, the Funds, other iShares funds or exchange-traded products. BFA Entities make payments for Intermediaries’ participation in activities that are designed to make registered representatives, other professionals and individual investors more knowledgeable about exchange-traded products, including the Funds and other iShares funds, or for other activities, such as participation in marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems (“Education Costs”). BFA Entities also make payments to Intermediaries for certain printing, publishing and mailing costs or materials relating to the Funds, other iShares funds or exchange-traded products (“Publishing Costs”). In addition, BFA Entities make payments to Intermediaries that make shares of the Funds, other iShares funds or exchange-traded products available to their clients, develop new products that feature iShares or otherwise promote the Funds, other iShares funds and exchange-traded products. BFA Entities may also reimburse expenses or make payments from their own assets to Intermediaries or other persons in consideration of services or other activities that the BFA Entities believe may benefit the iShares business or facilitate investment in the Funds, other iShares funds or exchange-traded products. Payments of the type described above are sometimes referred to as revenue-sharing payments.

Payments to an Intermediary may be significant to the Intermediary, and amounts that Intermediaries pay to your salesperson or other investment professional may also be significant for your salesperson or other investment professional. Because an Intermediary may make decisions about which investment options it will recommend or make available to its clients or what services to provide for various products based on payments it receives or is eligible to receive, such payments may create conflicts of interest between the Intermediary and its clients and these financial incentives may cause the Intermediary to recommend the Funds, other iShares funds or exchange-traded products over other investments. The same conflicts of interest and financial incentives exist with respect to your salesperson or other investment professional if he or she receives similar payments from his or her Intermediary firm.

150

customary digital marketing support and promotion of the Funds, other iShares funds, exchange-traded products and BlackRock mutual funds.

Further, BFA Entities make Education Costs and Publishing Costs payments to other Intermediaries that are not listed above. BFA Entities may determine to make such payments based on any number of metrics. For example, BFA Entities may make payments at year-end or other intervals in a fixed amount, an amount based upon an Intermediary’s services at defined levels or an amount based on the Intermediary’s net sales of one or more iShares funds in a year or other period, any of which arrangements may include an agreed-upon minimum or maximum payment, or any combination of the foregoing. As of the date of this SAI, BFA anticipates that the payments paid by BFA Entities in connection with the Funds, iShares funds and exchange-traded products in general will be immaterial to BFA Entities in the aggregate for the next year. Please contact your salesperson or other investment professional for more information regarding any such payments or financial incentives his or her Intermediary firm may receive. Any payments made, or financial incentives offered, by the BFA Entities to an Intermediary may create the incentive for the Intermediary to encourage customers to buy shares of the Funds, other iShares funds or other exchange-traded products.

Determination of Net Asset Value

151

Equity Investments. Equity securities traded on a recognized securities exchange (e.g., NYSE), on separate trading boards of a securities exchange or through a market system that provides contemporaneous transaction pricing information (each, an “Exchange”) are valued using information obtained via independent pricing services, generally at the closing price on the Exchange on which the security is primarily traded, or if an Exchange closing price is not available, the last traded price on that Exchange prior to the time as of which a Fund’s assets or liabilities are valued. However, under certain circumstances, other means of determining current market value may be used. If an equity security is traded on more than one Exchange, the current market value of the security where it is primarily traded generally will be used. In the event that there are no sales involving an equity security held by a Fund on a day on which a Fund values such security, the prior day’s price will be used, unless, in accordance with valuation procedures approved by the Board (the “Valuation Procedures”), BlackRock determines in good faith that such prior day’s price no longer reflects the fair value of the security, in which case such asset would be treated as a Fair Value Asset (as defined below).

Options, Futures, Swaps and Other Derivatives. Exchange-traded equity options for which market quotations are readily available are valued at the mean of the last bid and ask prices as quoted on the Exchange or the board of trade on which such options are traded. In the event that there is no mean price available for an exchange traded equity option held by a Fund on a day on which a Fund values such option, the last bid (long positions) or ask (short positions) price, if available, will be used as the value of such option. If no such bid or ask price is available on a day on which a Fund values such option, the prior day’s price will be used, unless BlackRock determines in good faith that such prior day’s price no longer reflects the fair value of the option, in which case such option will be treated as a Fair Value Asset (as defined below). OTC derivatives are valued using the last available bid prices or current market quotations provided by dealers or prices (including evaluated prices) supplied by a Fund’s approved independent third-party pricing services, each in accordance with the Valuation Procedures. OTC derivatives may be valued using a mathematical model which may incorporate a number of market data factors. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their settle price as of the close of such exchanges. Swap agreements and other derivatives are generally valued daily based upon quotations from market makers or by a pricing service in accordance with the Valuation Procedures.

Underlying Funds. Shares of underlying ETFs will be valued at their most recent closing price on an Exchange. Shares of underlying money market funds will be valued at their NAV.

All cash, receivables and current payables are carried on a Fund’s books at their face value.

152

In the event that application of the methods of valuation discussed above result in a price for a security which is deemed not to be representative of the fair market value of such security, the security will be valued by, under the direction of or in accordance with a method approved by the Board as reflecting fair value. All other assets and liabilities (including securities for which market quotations are not readily available) held by a Fund (including restricted securities) are valued at fair value as determined in good faith by the Board or by BlackRock (its delegate) pursuant to the Valuation Procedures. Any assets and liabilities that are denominated in a foreign currency are converted into U.S. dollars using prevailing market rates on the date of valuation as quoted by one or more data service providers.

Fair Value. When market quotations are not readily available or are believed in good faith by BlackRock to be unreliable, a Fund’s investments are valued at fair value (“Fair Value Assets”). Fair Value Assets are valued by BlackRock in accordance with the Valuation Procedures. BlackRock may reasonably conclude that a market quotation is not readily available or is unreliable if, among other things, a security or other asset or liability does not have a price source due to its complete lack of trading, if BlackRock believes in good faith that a market quotation from a broker-dealer or other source is unreliable (e.g., where it varies significantly from a recent trade, or no longer reflects the fair value of the security or other asset or liability subsequent to the most recent market quotation), or where the security or other asset or liability is only thinly traded or due to the occurrence of a significant event subsequent to the most recent market quotation. For this purpose, a “significant event” is deemed to occur if BlackRock determines, in its reasonable business judgment, that an event has occurred after the close of trading for an asset or liability but prior to or at the time of pricing a Fund’s assets or liabilities, and that the event is likely to cause a material change to the closing market price of the assets or liabilities held by a Fund. Non-U.S. securities whose values are affected by volatility that occurs in the markets or in related or highly correlated assets (e.g., ADRs, GDRs or ETFs that invest in components of the Underlying Index) on a trading day after the close of non-U.S. securities markets may be fair valued. On any day the NYSE is open and a foreign market or the primary exchange on which a foreign asset or liability is traded is closed, such asset or liability will be valued using the prior day’s price, provided that BlackRock is not aware of any significant event or other information that would cause such price to no longer reflect the fair value of the asset or liability, in which case such asset or liability would be treated as a Fair Value Asset.

BlackRock, with input from the BlackRock Investment Strategy Group, will submit its recommendations regarding the valuation and/or valuation methodologies for Fair Value Assets to BlackRock’s Valuation Committee. The BlackRock Valuation Committee may accept, modify or reject any recommendations. In addition, a Fund’s accounting agent periodically endeavors to confirm the prices it receives from all third-party pricing services, index providers and broker-dealers, and, with the assistance of BlackRock, to regularly evaluate the values assigned to the securities and other assets and liabilities of a Fund. The pricing of all Fair Value Assets is subsequently reported to and, where appropriate, ratified by the Board.

153

Fair value represents a good faith approximation of the value of an asset or liability. When determining the fair value of an asset, one or more of a variety of fair valuation methodologies may be used (depending on certain factors, including the asset type). For example, the asset may be priced on the basis of the original cost of the investment or, alternatively, using proprietary or third-party models (including models that rely upon direct portfolio management pricing inputs and which reflect the significance attributed to the various factors and assumptions being considered). Prices of actual, executed or historical transactions in the relevant asset and/or liability (or related or comparable assets and/or liabilities) or, where appropriate, an appraisal by a third-party experienced in the valuation of similar assets and/or liabilities, may also be used as a basis for establishing the fair value of an asset or liability. The fair value of one or more assets or liabilities may not, in retrospect, be the price at which those assets or liabilities could have been sold during the period in which the particular fair values were used in determining a Fund’s NAV. As a result, a Fund’s sale or redemption of its shares at NAV, at a time when a holding or holdings are valued at fair value, may have the effect of diluting or increasing the economic interest of existing shareholders.

Brokerage Transactions

154

services provided by that broker or dealer. This includes commissions paid on riskless principal transactions in securities under certain conditions.

The Funds anticipate that brokerage transactions involving foreign equity securities generally will be conducted primarily on the principal stock exchanges of the applicable country. Foreign equity securities may be held by the Funds in the form of depositary receipts, or other securities convertible into foreign equity securities. Depositary receipts may be listed on stock exchanges, or traded in OTC markets in the U.S. or Europe, as the case may be. ADRs, like other securities traded in the U.S., will be subject to negotiated commission rates.

OTC issues, including most fixed-income securities such as corporate debt and U.S. Government securities, are normally traded on a “net” basis without a stated commission, through dealers acting for their own account and not as brokers. The Funds will primarily engage in transactions with these dealers or deal directly with the issuer unless a better price or execution could be obtained by using a broker. Prices paid to a dealer with respect to both foreign and domestic securities will generally include a “spread,” which is the difference between the prices at which the dealer is willing to purchase and sell the specific security at the time, and includes the dealer’s normal profit.

155

accounts. BFA and the other Affiliates may deal, trade and invest for their own respective accounts in the types of securities in which the Funds may invest.

Initial public offerings (“IPOs”) of securities may be over-subscribed and subsequently trade at a premium in the secondary market. When BFA is given an opportunity to invest in such an initial offering or “new” or “hot” issue, the supply of securities available for client accounts is often less than the amount of securities the accounts would otherwise take. In order to allocate these investments fairly and equitably among client accounts over time, each portfolio manager or a member of his or her respective investment team will indicate to BFA’s trading desk their level of interest in a particular offering with respect to eligible clients’ accounts for which that team is responsible. IPOs of U.S. equity securities will be identified as eligible for particular client accounts that are managed by portfolio teams who have indicated interest in the offering based on market capitalization of the issuer of the security and the investment mandate of the client account and in the case of international equity securities, the country where the offering is taking place and the investment mandate of the client account. Generally, shares received during the IPO will be allocated among participating client accounts within each investment mandate on a pro rata basis. This pro rata allocation may result in a Fund receiving less of a particular security than if pro-rating had not occurred. All allocations of securities will be subject, where relevant, to share minimums established for accounts and compliance constraints. In situations where supply is too limited to be allocated among all accounts for which the investment is eligible, portfolio managers may rotate such investment opportunities among one or more accounts so long as the rotation system provides for fair access for all client accounts over time. Other allocation methodologies that are considered by BFA to be fair and equitable to clients may be used as well.

Because different accounts may have differing investment objectives and policies, BFA may buy and sell the same securities at the same time for different clients based on the particular investment objective, guidelines and strategies of those accounts. For example, BFA may decide that it may be entirely appropriate for a growth fund to sell a security at the same time a value fund is buying that security. To the extent that transactions on behalf of more than one client of BFA or the other Affiliates during the same period may increase the demand for securities being purchased or the supply of securities being sold, there may be an adverse effect on price. For example, sales of a security by BlackRock on behalf of one or more of its clients may decrease the market price of such security, adversely impacting other BlackRock clients that still hold the security. If purchases or sales of securities arise for consideration at or about the same time that would involve the Funds or other clients or funds for which BFA or another Affiliate act as investment manager, transactions in such securities will be made, insofar as feasible, for the respective funds and clients in a manner deemed equitable to all.

In certain instances, BFA may find it efficient for purposes of seeking to obtain best execution, to aggregate or “bunch” certain contemporaneous purchases or sale orders of its advisory accounts and advisory accounts of affiliates. In general, all contemporaneous trades for client accounts under management by the same portfolio manager or investment team will be bunched in a single order if the trader believes the bunched trade would provide each client with an opportunity to achieve a more favorable execution at a potentially lower execution cost. The costs associated with a bunched order will be shared pro rata among the clients in the bunched order. Generally, if an order for a particular portfolio manager or management team is filled at several different prices through multiple trades, all accounts participating in the order will receive the average price (except in the case of certain international markets where average pricing is not permitted). While in some cases this practice could have a detrimental effect upon the price or value of the security as far as the Funds are concerned, in other cases it could be beneficial to the Funds. Transactions effected by BFA or the other Affiliates on behalf of more than one of its clients during the same period may increase the demand for securities being purchased or the supply of securities being sold, causing an adverse effect on price. The trader will give the bunched order to the broker-dealer that the trader has identified as being able to provide the best execution of the order. Orders for purchase or sale of securities will be placed within a reasonable amount of time of the order receipt and bunched orders will be kept bunched only long enough to execute the order.

The table below sets forth the brokerage commissions paid by each Fund for the fiscal years noted. Any differences in brokerage commissions paid by a Fund from year to year are principally due to increases or decreases in that Fund’s assets over those periods or the magnitude of changes to the components of a Fund's Underlying Index:

Additional Information Concerning the Trust

Shareholders may make inquiries by writing to iShares Trust, c/o BlackRock Investments, LLC, 1 University Square Drive, Princeton, NJ 08540.

Absent an applicable exemption or other relief from the SEC or its staff, beneficial owners of more than 5% of the shares of a fund may be subject to the reporting provisions of Section 13 of the 1934 Act and the SEC’s rules promulgated thereunder. In addition, absent an applicable exemption or other relief from the SEC or its staff, officers and trustees of a fund and beneficial owners of 10% of the shares of a fund (“Insiders”) may be subject to the insider reporting, short-swing profit and short sale provisions of Section 16 of the 1934 Act and the SEC’s rules promulgated thereunder. Beneficial owners and Insiders should consult with their own legal counsel concerning their obligations under Sections 13 and 16 of the 1934 Act and existing guidance provided by the SEC staff.

163

In accordance with the Trust's current Agreement and Declaration of Trust (the “Declaration of Trust”), the Board may, without shareholder approval (unless such shareholder approval is required by the Declaration of Trust or applicable law, including the 1940 Act), authorize certain funds to merge, reorganize, consolidate, sell all or substantially all of their assets, or take other similar actions with, to or into another fund. The Trust or a Fund may be terminated by a majority vote of the Board, subject to the affirmative vote of a majority of the shareholders of the Trust or such Fund entitled to vote on termination; however, in certain circumstances described in the Declaration of Trust, only a majority vote of the Board is required. Although the shares are not automatically redeemable upon the occurrence of any specific event, the Declaration of Trust provides that the Board will have the unrestricted power to alter the number of shares in a Creation Unit. Therefore, in the event of a termination of the Trust or a Fund, the Board, in its sole discretion, could determine to permit the shares to be redeemable in aggregations smaller than Creation Units or to be individually redeemable. In such circumstance, the Trust or a Fund may make redemptions in-kind, for cash or for a combination of cash or securities. Further, in the event of a termination of the Trust or a Fund, the Trust or a Fund might elect to pay cash redemptions to all shareholders, with an in-kind election for shareholders owning in excess of a certain stated minimum amount.

DTC as Securities Depository for Shares of the Funds. Shares of each Fund are represented by securities registered in the name of DTC or its nominee and deposited with, or on behalf of, DTC.

DTC was created in 1973 to enable electronic movement of securities between its participants (“DTC Participants”), and NSCC was established in 1976 to provide a single settlement system for securities clearing and to serve as central counterparty for securities trades among DTC Participants. In 1999, DTC and NSCC were consolidated within The Depository Trust & Clearing Corporation (“DTCC”) and became wholly-owned subsidiaries of DTCC. The common stock of DTCC is owned by the DTC Participants, but NYSE and FINRA, through subsidiaries, hold preferred shares in DTCC that provide them with the right to elect one member each to the DTCC board of directors. Access to the DTC system is available to entities, such as banks, brokers, dealers and trust companies, that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly (“Indirect Participants”).

Share distributions shall be made to DTC or its nominee, Cede & Co., as the registered holder of all shares of the Trust. DTC or its nominee, upon receipt of any such distributions, shall credit immediately DTC Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in shares of each Fund as shown on the records of DTC or its nominee. Payments by DTC Participants to Indirect Participants and Beneficial Owners of shares held through such DTC Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a “street name,” and will be the responsibility of such DTC Participants.

164

Any Selling Shareholder and any other person participating in such distribution will be subject to applicable provisions of the 1934 Act and the rules and regulations thereunder.

Creation and Redemption of Creation Units

General. The Trust issues and sells shares of each Fund only in Creation Units on a continuous basis through the Distributor or its agent, without a sales load, at a price based on the NAV next determined after receipt, on any Business Day (as defined below), of an order received by the Distributor or its agent in proper form. On days when the applicable Listing Exchange closes earlier than normal, the Funds may require orders to be placed earlier in the day. The following table sets forth the number of shares of a Fund that constitute a Creation Unit for such Fund and the approximate value of such Creation Unit as of April 30, 2018 (except as noted):

Fund Deposit. The consideration for purchase of Creation Units of a Fund generally consists of the Deposit Securities and the Cash Component computed as described below. Together, the Deposit Securities and the Cash Component constitute the “Fund Deposit,” which, when combined with the Fund's portfolio securities, is designed to generate performance that has a collective investment profile similar to that of the Underlying Index. The Fund Deposit represents the minimum initial and subsequent investment amount for a Creation Unit of any Fund.

BFA makes available through the NSCC on each Business Day prior to the opening of business on the Listing Exchange, the list of names and the required number of shares of each Deposit Security and the amount of the Cash Component to be included in the current Fund Deposit (based on information as of the end of the previous Business Day for each Fund). Such Fund Deposit is applicable, subject to any adjustments as described below, to purchases of Creation Units of shares of a given Fund until such time as the next-announced Fund Deposit is made available.

The identity and number of shares of the Deposit Securities change pursuant to changes in the composition of a Fund's portfolio and as rebalancing adjustments and corporate action events are reflected from time to time by BFA with a view to the investment objective of the Fund. The composition of the Deposit Securities may also change in response to adjustments to the weighting or composition of the component securities constituting the relevant Underlying Index.

Cash Purchase Method. Although the Trust does not generally permit partial or full cash purchases of Creation Units of its funds, when partial or full cash purchases of Creation Units are available or specified for a Fund, they will be effected in essentially the same manner as in-kind purchases thereof. In the case of a partial or full cash purchase, the Authorized Participant must pay the cash equivalent of the Deposit Securities it would otherwise be required to provide through an in-kind purchase, plus the same Cash Component required to be paid by an in-kind purchaser.

167

The Authorized Participant is responsible for any and all expenses and costs incurred by a Fund, including any applicable cash amounts, in connection with any purchase order.

Timing of Submission of Purchase Orders. An Authorized Participant must submit an irrevocable order to purchase shares of a Fund generally before 4:00 p.m., Eastern time on any Business Day in order to receive that day's NAV. Creation Orders must be transmitted by an Authorized Participant in the form required by the Funds to the Distributor or its agent pursuant to procedures set forth in the Authorized Participant Agreement. Economic or market disruptions or changes, or telephone or other communication failure, may impede the ability to reach the Distributor or its agent or an Authorized Participant. Orders to create shares of a Fund that are submitted on the Business Day immediately preceding a holiday or a day (other than a weekend) when the equity markets in the relevant non-U.S. market are closed may not be accepted. Each Fund's deadline specified above for the submission of purchase orders is referred to as that Fund's “Cutoff Time.” The Distributor or its agent, in their discretion, may permit the submission of such orders and requests by or through an Authorized Participant at any time (including on days on which the Listing Exchange is not open for business) via communication through the facilities of the Distributor's or its agent's proprietary website maintained for this purpose. Purchase orders and redemption requests, if accepted by the Trust, will be processed based on the NAV next determined after such acceptance in accordance with a Fund's Cutoff Times as provided in the Authorized Participant Agreement and disclosed in this SAI.

168

Acceptance of Orders for Creation Units. Subject to the conditions that (i) an irrevocable purchase order has been submitted by the Authorized Participant (either on its own or another investor's behalf) and (ii) arrangements satisfactory to the Funds are in place for payment of the Cash Component and any other cash amounts which may be due, the Funds will accept the order, subject to each Fund's right (and the right of the Distributor and BFA) to reject any order until acceptance, as set forth below.

Issuance of a Creation Unit. Except as provided herein, a Creation Unit will not be issued until the transfer of good title to the applicable Fund of the Deposit Securities and the payment of the Cash Component have been completed. When the sub-custodian has confirmed to the custodian that the securities included in the Fund Deposit (or the cash value thereof) have been delivered to the account of the relevant sub-custodian or sub-custodians, the Distributor or its agent and BFA shall be notified of such delivery and the applicable Fund will issue and cause the delivery of the Creation Unit.

For the iShares Global Consumer Discretionary ETF, iShares Global Industrials ETF, iShares Global Telecom ETF, iShares International Developed Property ETF and iShares JPX-Nikkei 400 ETF, Creation Units are generally issued on a “T+3 basis” (i.e., three Business Days after trade date). However, each Fund reserves the right to settle Creation Unit transactions on a basis other than T+2 or T+3, including a shorter settlement period, if necessary or appropriate under the circumstances and compliant with applicable law. For example, certain Funds reserve the right to settle Creation Unit transactions on a basis other than T+2 or T+3, in order to accommodate non-U.S. market holiday schedules (as discussed in Appendix B of this SAI), to account for different treatment among non-U.S. and U.S. markets of dividend record dates and ex-dividend dates (i.e., the last day the holder of a security can sell the security and still receive dividends payable on the security) and in certain other circumstances.

part or in whole, in reliance on the undertaking of the Authorized Participant to deliver the missing Deposit Securities as soon as possible, which undertaking shall be secured by such Authorized Participant's delivery and maintenance of collateral having a value at least equal to 105% and up to 115%, which percentage BFA may change at any time, in its sole discretion, of the value of the missing Deposit Securities in accordance with the Funds' then-effective procedures. The Trust may use such cash deposit at any time to buy Deposit Securities for the Funds. The only collateral that is acceptable to the Funds is cash in U.S. dollars. Such cash collateral must be delivered no later than the time specified by a Fund or its custodian on the contractual settlement date. The cash collateral posted by the Authorized Participant may be invested at the risk of the Authorized Participant, and income, if any, on invested cash collateral will be paid to that Authorized Participant. Information concerning the Funds' current procedures for collateralization of missing Deposit Securities is available from the Distributor or its agent. The Authorized Participant Agreement will permit the Funds to buy the missing Deposit Securities at any time and will subject the Authorized Participant to liability for any shortfall between the cost to the Funds of purchasing such securities and the cash collateral including, without limitation, liability for related brokerage, borrowings and other charges.

Costs Associated with Creation Transactions. A standard creation transaction fee is imposed to offset the transfer and other transaction costs associated with the issuance of Creation Units. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same, regardless of the number of Creation Units purchased by the Authorized Participant on the applicable Business Day. If a purchase consists solely or partially of cash, the Authorized Participant may also be required to cover (up to the maximum amount shown below) certain brokerage, tax, foreign exchange, execution, price movement and other costs and expenses related to the execution of trades resulting from such transaction (which may, in certain instances, be based on a good faith estimate of transaction costs). Authorized Participants will also bear the costs of transferring the Deposit Securities to the Funds. Certain fees/costs associated with creation transactions may be waived in certain circumstances. Investors who use the services of a broker or other financial intermediary to acquire Fund shares may be charged a fee for such services.

The following table sets forth each Fund's standard creation transaction fees and maximum additional charge (as described above):

Redemption of iShares Russell 2000 ETF During Certain Market Conditions. By submitting a redemption request, an Authorized Participant is deemed to represent to the Trust, consistent with the Authorized Participant Agreement, that (1) it has the requisite number of shares to deliver to the Trust to satisfy the redemption request, (2) such shares have not been loaned or pledged to any other party and are free and clear of any liens and encumbrances, and (3) it will not lend, hypothecate or otherwise encumber the shares after the submission of the redemption request. These deemed representations are subject to verification under certain circumstances with respect to the iShares Russell 2000 ETF.

171

Specifically, if an Authorized Participant submits a redemption request with respect to the iShares Russell 2000 ETF on a Business Day on which the Trust determines, based on information available to the Trust on such Business Day, that (i) the short interest of the Fund in the marketplace is greater than or equal to 150% and (ii) the orders in the aggregate from all Authorized Participants redeeming Fund shares on such Business Day represent 25% or more of the shares outstanding of the Fund, such Authorized Participant will be required to verify to the Trust (in a form specified by the Trust) the accuracy of its deemed representations. If, after receiving notice of the verification requirement, the Authorized Participant does not verify the accuracy of its deemed representations in accordance with this requirement, its redemption request will be considered not to have been timely received in proper form.

BFA makes available through the NSCC, prior to the opening of business on the Listing Exchange on each Business Day, the designated portfolio of securities (including any portion of such securities for which cash may be substituted) that will be applicable (subject to possible amendment or correction) to redemption requests received in proper form (as defined below) on that day (“Fund Securities”), and an amount of cash (the “Cash Amount,” as described below). Such Fund Securities and the corresponding Cash Amount (each subject to possible amendment or correction) are applicable, in order to effect redemptions of Creation Units of a Fund until such time as the next announced composition of the Fund Securities and Cash Amount is made available. Fund Securities received on redemption may not be identical to Deposit Securities that are applicable to creations of Creation Units. Procedures and requirements governing redemption transactions are set forth in the handbook for Authorized Participants and may change from time to time.

The Trust may, in its sole discretion, substitute a “cash in lieu” amount to replace any Fund Security. The Trust also reserves the right to permit or require a “cash in lieu” amount in certain circumstances, including circumstances in which: (i) the delivery of a Fund Security to the Authorized Participant would be restricted under applicable securities or other local laws; or (ii) the delivery of a Fund Security to the Authorized Participant would result in the disposition of the Fund Security by the Authorized Participant due to restrictions under applicable securities or other local laws, or in certain other situations. The amount of cash paid out in such cases will be equivalent to the value of the substituted security listed as a Fund Security. In the event that the Fund Securities have a value greater than the NAV of the shares, a compensating cash payment equal to the difference is required to be made by or through an Authorized Participant by the redeeming shareholder. Each Fund generally redeems Creation Units for Fund Securities, but each Fund reserves the right to utilize a cash option for redemption of Creation Units. Each Fund may, in its sole discretion, provide such redeeming Authorized Participant a portfolio of securities that differs from the exact composition of the Fund Securities, but does not differ in NAV.

Cash Redemption Method. Although the Trust does not generally permit partial or full cash redemptions of Creation Units of its funds, when partial or full cash redemptions of Creation Units are available or specified for a Fund, they will be effected in essentially the same manner as in-kind redemptions thereof. In the case of partial or full cash redemption, the Authorized Participant receives the cash equivalent of the Fund Securities it would otherwise receive through an in-kind redemption, plus the same Cash Amount to be paid to an in-kind redeemer.

number of Creation Units redeemed by an Authorized Participant on the applicable Business Day. If a redemption consists solely or partially of cash, the Authorized Participant may also be required to cover (up to the maximum amount shown below) certain brokerage, tax, foreign exchange, execution, price movement and other costs and expenses related to the execution of trades resulting from such transaction (which may, in certain instances, be based on a good faith estimate of transaction costs). Authorized Participants will also bear the costs of transferring the Fund Securities from a Fund to their account on their order. Certain fees/costs associated with redemption transactions may be waived in certain circumstances. Investors who use the services of a broker or other financial intermediary to dispose of Fund shares may be charged a fee for such services.

For the iShares Global Consumer Discretionary ETF, iShares Global Industrials ETF, iShares Global Telecom ETF, iShares International Developed Property ETF and iShares JPX-Nikkei 400 ETF, deliveries of redemption proceeds are generally made within three Business Days (i.e., “T+3”). However, each Fund reserves the right to settle deliveries of redemption proceeds on a basis other than T+2 or T+3, including a shorter settlement period, if necessary or appropriate under the circumstances and compliance with applicable law. For example, certain Funds reserve the right to settle redemption transactions on a basis other than T+2 or T+3 to accommodate non-U.S. market holiday schedules (as discussed in Appendix B of this SAI), to account for different treatment among non-U.S. and U.S. markets of dividend record dates and dividend ex-dates (i.e., the last date the holder of a security can sell the security and still receive dividends payable on the security sold) and in certain other circumstances. Appendix B of this SAI identifies the instances, if any, where more than seven days would be needed to deliver redemption proceeds for such Funds. Pursuant to an order of the SEC, for such Funds, the Trust will make delivery of redemption proceeds within the number of days stated in Appendix B of this SAI to be the maximum number of days necessary to deliver redemption proceeds.

If neither the redeeming Beneficial Owner nor the Authorized Participant acting on behalf of such redeeming Beneficial Owner has appropriate arrangements to take delivery of Fund Securities in the applicable non-U.S. jurisdiction and it is not possible to make other such arrangements, or if it is not possible to effect deliveries of Fund Securities in such jurisdiction, a Fund may in its discretion exercise its option to redeem such shares in cash, and the redeeming Beneficial Owner will be required to receive its redemption proceeds in cash. In such case, the investor will receive a cash payment equal to the net asset value of its shares based on the NAV of the relevant Fund next determined after the redemption request is received in proper form (minus a redemption transaction fee and additional charges specified above to offset the Fund's brokerage and other transaction costs associated with the disposition of Fund Securities). Redemptions of shares for Fund Securities will be subject to compliance with applicable U.S. federal and state securities laws and each Fund (whether or not it otherwise permits cash redemptions) reserves the right to redeem Creation Units for cash to the extent that the Fund cannot lawfully deliver specific Fund Securities upon redemptions or cannot do so without first registering the Fund Securities under such laws.

Although the Trust does not ordinarily permit cash redemptions of Creation Units, in the event that cash redemptions are permitted or required by the Trust, proceeds will be paid to the Authorized Participant redeeming shares as soon as practicable after the date of redemption (within seven calendar days thereafter, except for the instances listed in Appendix B to this SAI in which more than seven calendar days would be needed).

To the extent contemplated by an Authorized Participant's agreement with the Distributor or its agent, in the event an Authorized Participant has submitted a redemption request in proper form but is unable to transfer all or part of the Creation Unit to be redeemed to a Fund, at or prior to 10:00 a.m., Eastern time on the Listing Exchange business day after the date of submission of such redemption request, the Distributor or its agent will accept the redemption request in reliance on the undertaking by the Authorized Participant to deliver the missing shares as soon as possible. Such undertaking shall be secured by the Authorized Participant's delivery and maintenance of collateral consisting of cash, in U.S. dollars in immediately available funds, having a value at least equal to 105% and up to 115%, which percentage BFA may change at any time, in its sole discretion, of the value of the missing shares. Such cash collateral must be delivered no later than the time specified by a Fund or its Custodian on the day after the date of submission of such redemption request and shall be held by State Street and marked-to-market daily. The fees of State Street and any sub-custodians in respect of the delivery, maintenance and redelivery of the cash collateral shall be payable by the Authorized Participant. The cash collateral posted by the Authorized Participant may be invested at the risk of the Authorized Participant, and income, if any, on invested cash collateral will be paid to that Authorized Participant. The Authorized Participant Agreement permits the Funds to acquire shares of the Funds at any time and subjects the Authorized Participant to liability for any shortfall between the aggregate of the cost to the Funds of purchasing such shares, plus the value of the Cash Amount, and the value of the cash collateral together with liability for related brokerage and other charges.

Because the portfolio securities of a Fund may trade on exchange(s) on days that the Listing Exchange is closed or are otherwise not Business Days for such Fund, shareholders may not be able to redeem their shares of such Fund, or purchase or sell shares of such Fund on the Listing Exchange on days when the NAV of such a Fund could be significantly affected by events in the relevant non-U.S. markets.

The right of redemption may be suspended or the date of payment postponed with respect to any Fund: (i) for any period during which the applicable Listing Exchange is closed (other than customary weekend and holiday closings); (ii) for any period during which trading on the applicable Listing Exchange is suspended or restricted; (iii) for any period during which an emergency exists as a result of which disposal of the shares of the Fund's portfolio securities or determination of its net asset value is not reasonably practicable; or (iv) in such other circumstance as is permitted by the SEC.

Taxes

The following is a summary of certain material U.S. federal income tax considerations regarding the purchase, ownership and disposition of shares of a Fund. This summary does not address all of the potential U.S. federal income tax consequences that may be applicable to a Fund or to all categories of investors, some of which may be subject to special tax rules. Current and prospective shareholders are urged to consult their own tax advisors with respect to the specific U.S. federal, state, local and non-U.S. tax consequences of investing in a Fund. The summary is based on the laws and judicial and administrative interpretations thereof in effect on the date of this SAI, all of which are subject to change, possibly with retroactive effect.

and, without further legislation, will not apply after 2025. The application of certain provisions of the Tax Act is uncertain, and the changes in the act may have indirect effects on a Fund, its investments and its shareholders that cannot be predicted. In addition, legislative, regulatory or administrative changes could be enacted or promulgated at any time, either prospectively or with retroactive effect. Prospective investors should consult their tax advisors regarding the implications of the Tax Act on their investment in a Fund.

Regulated Investment Company Qualifications. Each Fund intends to continue to qualify for treatment as a separate RIC under Subchapter M of the Internal Revenue Code. To qualify for treatment as a RIC, each Fund must annually distribute at least 90% of its investment company taxable income (which includes dividends, interest and net short-term capital gains) and meet several other requirements. Among such other requirements are the following: (i) at least 90% of each Fund’s annual gross income must be derived from dividends, interest, payments with respect to securities loans, gains from the sale or other disposition of stock or securities or non-U.S. currencies, other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies, and net income derived from interests in qualified publicly-traded partnerships (i.e., partnerships that are traded on an established securities market or tradable on a secondary market, other than partnerships that derive at least 90% of their income from interest, dividends, capital gains and other traditionally permitted RIC income); and (ii) at the close of each quarter of each Fund's taxable year, (a) at least 50% of the market value of each Fund’s total assets must be represented by cash and cash items, U.S. government securities, securities of other RICs and other securities, with such other securities limited for purposes of this calculation in respect of any one issuer to an amount not greater than 5% of the value of the Fund’s assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of each Fund's total assets may be invested in the securities (other than U.S. government securities or the securities of other RICs) of any one issuer, of two or more issuers of which 20% or more of the voting stock is held by the Fund and that are engaged in the same or similar trades or businesses or related trades or businesses, or the securities of one or more qualified publicly-traded partnerships.

Although, in general, the passive loss rules of the Internal Revenue Code do not apply to RICs, such rules do apply to a RIC with respect to items attributable to interests in qualified publicly-traded partnerships. A Fund's investments in partnerships, including in qualified publicly-traded partnerships, may result in the Fund being subject to state, local, or non-U.S. income, franchise or withholding tax liabilities.

Taxation of RICs. As a RIC, a Fund will not be subject to U.S. federal income tax on the portion of its taxable investment income and capital gains that it distributes to its shareholders, provided that it satisfies a minimum distribution requirement. To satisfy the minimum distribution requirement, a Fund must distribute to its shareholders at least the sum of (i) 90% of its “investment company taxable income” (i.e., income other than its net realized long-term capital gain over its net realized short-term capital loss), plus or minus certain adjustments, and (ii) 90% of its net tax-exempt income for the taxable year. A Fund will be subject to income tax at regular corporate rates on any taxable income or gains that it does not distribute to its shareholders. If a Fund fails to qualify for any taxable year as a RIC or fails to meet the distribution requirement, all of its taxable income will be subject to tax at regular corporate income tax rates without any deduction for distributions to shareholders, and such distributions generally will be taxable to shareholders as ordinary dividends to the extent of the Fund’s current and accumulated earnings and profits. In such event, distributions to individuals should be eligible to be treated as qualified dividend income and distributions to corporate shareholders generally should be eligible for the dividends received deduction. Although each Fund intends to distribute substantially all of its net investment income and its capital gains for each taxable year, each Fund will be subject to U.S. federal income taxation to the extent any such income or gains are not distributed. If a Fund fails to qualify as a RIC in any year, it must pay out its earnings and profits accumulated in that year in order to qualify again as a RIC. If a Fund fails to qualify as a RIC for a period greater than two taxable years, the Fund may be required to recognize any net built-in gains with respect to certain of its assets (i.e., the excess of the aggregate gains, including items of income, over aggregate losses that would have been realized with respect to such assets if the Fund had been liquidated) if it qualifies as a RIC in a subsequent year.

177

Net Capital Loss Carryforwards. Net capital loss carryforwards may be applied against any net realized capital gains in each succeeding year, until they have been reduced to zero or until their respective expiration dates, whichever occurs first. Capital loss carryforwards from taxable years beginning after 2010 are not subject to expiration, and short-term and long-term capital loss carryforwards from such taxable years may only be applied against net realized short-term and long-term capital gains, respectively.

The following Funds had net capital loss carryforwards, as set forth in the table below, as of March 31, 2018, the tax year-end for the Funds:

¹	Must be utilized prior to losses subject to expiration.

Taxation of U.S. Shareholders. Dividends and other distributions by a Fund are generally treated under the Internal Revenue Code as received by the shareholders at the time the dividend or distribution is made. However, any dividend or distribution declared by a Fund in October, November or December of any calendar year and payable to shareholders of record on a specified date in such a month shall be deemed to have been received by each shareholder on December 31 of such calendar year and to have been paid by the Fund not later than such December 31, provided such dividend is actually paid by the Fund during January of the following calendar year.

179

Each Fund intends to distribute annually to its shareholders substantially all of its investment company taxable income and any net realized long-term capital gains in excess of net realized short-term capital losses (including any capital loss carryovers). However, if a Fund retains for investment an amount equal to all or a portion of its net long-term capital gains in excess of its net short-term capital losses (including any capital loss carryovers), it will be subject to a corporate tax (at a flat rate of 21%) on the amount retained. In that event, the Fund will designate such retained amounts as undistributed capital gains in a notice to its shareholders who (a) will be required to include in income for U.S. federal income tax purposes, as long-term capital gains, their proportionate shares of the undistributed amount, (b) will be entitled to credit their proportionate shares of the tax paid by the Fund on the undistributed amount against their U.S. federal income tax liabilities, if any, and to claim refunds to the extent their credits exceed their liabilities, if any, and (c) will be entitled to increase their tax basis, for U.S. federal income tax purposes, in their shares by an amount equal to the excess of the amount in clause (a) over the amount in clause (b). Organizations or persons not subject to U.S. federal income tax on such capital gains will be entitled to a refund of their pro rata share of such taxes paid by the Fund upon filing appropriate returns or claims for refund with the IRS.

Distributions of net realized long-term capital gains, if any, that a Fund reports as capital gains dividends are taxable as long-term capital gains, whether paid in cash or in shares and regardless of how long a shareholder has held shares of the Fund. All other dividends of a Fund (including dividends from short-term capital gains) from its current and accumulated earnings and profits (“regular dividends”) are generally subject to tax as ordinary income, subject to the discussion of qualified dividend income below. Long-term capital gains are eligible for taxation at a maximum rate of 15% or 20% for non-corporate shareholders, depending on whether their income exceeds certain threshold amounts.

Investors considering buying shares just prior to a dividend or capital gain distribution should be aware that, although the price of shares purchased at that time may reflect the amount of the forthcoming distribution, such dividend or distribution may nevertheless be taxable to them. If a Fund is the holder of record of any security on the record date for any dividends payable with respect to such security, such dividends will be included in the Fund’s gross income not as of the date received but as of the later of (a) the date such security became ex-dividend with respect to such dividends (i.e., the date on which a buyer of the security would not be entitled to receive the declared, but unpaid, dividends); or (b) the date the Fund acquired such security. Accordingly, in order to satisfy its income distribution requirements, a Fund may be required to pay dividends based on anticipated earnings, and shareholders may receive dividends in an earlier year than would otherwise be the case.

In certain situations, a Fund may, for a taxable year, defer all or a portion of its net capital loss (or if there is no net capital loss, then any net long-term or short-term capital loss) realized after October and its late-year ordinary loss (defined as the sum of (i) the excess of post-October foreign currency and passive foreign investment company (“PFIC”) losses over post-October foreign currency and PFIC gains and (ii) the excess of post-December ordinary losses over post-December ordinary income) until the next taxable year in computing its investment company taxable income and net capital gain, which will

180

defer the recognition of such realized losses. Such deferrals and other rules regarding gains and losses realized after October (or December) may affect the tax character of shareholder distributions.

Sales of Shares. Upon the sale or exchange of shares of a Fund, a shareholder will realize a taxable gain or loss equal to the difference between the amount realized and the shareholder’s basis in shares of the Fund. A redemption of shares by a Fund will be treated as a sale for this purpose. Such gain or loss will be treated as capital gain or loss if the shares are capital assets in the shareholder’s hands and will be long-term capital gain or loss if the shares are held for more than one year and short-term capital gain or loss if the shares are held for one year or less. Any loss realized on a sale or exchange will be disallowed to the extent the shares disposed of are replaced, including replacement through the reinvesting of dividends or capital gains distributions, or by an option or contract to acquire substantially identical shares, within a 61-day period beginning 30 days before and ending 30 days after the disposition of the shares. In such a case, the basis of the shares acquired will be increased to reflect the disallowed loss. Any loss realized by a shareholder on the sale of Fund shares held by the shareholder for six months or less will be treated for U.S. federal income tax purposes as a long-term capital loss to the extent of any distributions or deemed distributions of long-term capital gains received by the shareholder with respect to such share. The Medicare contribution tax described above will apply to the sale of Fund shares.

If a shareholder incurs a sales charge in acquiring shares of a Fund, disposes of those shares within 90 days and then, on or before January 31 of the following calendar year, acquires shares in a mutual fund for which the otherwise applicable sales charge is reduced by reason of a reinvestment right (e.g., an exchange privilege), the original sales charge will not be taken into account in computing gain/loss on the original shares to the extent the subsequent sales charge is reduced. Instead, the disregarded portion of the original sales charge will be added to the tax basis of the newly acquired shares. Furthermore, the same rule also applies to a disposition of the newly acquired shares made within 90 days of the second acquisition. This provision prevents shareholders from immediately deducting the sales charge by shifting their investments within a family of mutual funds.

Taxation of Certain Derivatives. A Fund’s transactions in zero coupon securities, non-U.S. currencies, forward contracts, options and futures contracts (including options and futures contracts on non-U.S. currencies), to the extent permitted, will be subject to special provisions of the Internal Revenue Code (including provisions relating to “hedging transactions” and “straddles”) that, among other consequences, may affect the character of gains and losses realized by the Fund (i.e., may affect whether gains or losses are ordinary or capital), accelerate recognition of income to the Fund and defer Fund losses. These rules could therefore affect the character, amount and timing of distributions to shareholders. These provisions also (a) will require a Fund to mark-to-market certain types of the positions in its portfolio (i.e., treat them as if they were closed out at the end of each year) and (b) may cause a Fund to recognize income without receiving cash with which to pay dividends or make distributions in amounts necessary to satisfy the distribution requirements for avoiding income and excise taxes. Each Fund will monitor its transactions, will make the appropriate tax elections and will make the appropriate entries in its books and records when it acquires any zero coupon security, non-U.S. currency, forward contract, option, futures contract or hedged investment in order to mitigate the effect of these rules and prevent disqualification of a Fund as a RIC.

181

A Fund’s investments in so-called “Section 1256 contracts,” such as regulated futures contracts, most non-U.S. currency forward contracts traded in the interbank market and options on most security indexes, are subject to special tax rules. All Section 1256 contracts held by a Fund at the end of its taxable year are required to be marked to their market value, and any unrealized gain or loss on those positions will be included in a Fund’s income as if each position had been sold for its fair market value at the end of the taxable year. The resulting gain or loss will be combined with any gain or loss realized by a Fund from positions in Section 1256 contracts closed during the taxable year. Provided such positions were held as capital assets and were not part of a “hedging transaction” nor part of a “straddle,” 60% of the resulting net gain or loss will be treated as long-term capital gain or loss, and 40% of such net gain or loss will be treated as short-term capital gain or loss, regardless of the period of time the positions were actually held by a Fund.

Qualified Dividend Income. Distributions by a Fund of investment company taxable income (including any short-term capital gains), whether received in cash or shares, will be taxable either as ordinary income or as qualified dividend income, which is eligible to be taxed at long-term capital gain rates to the extent a Fund receives qualified dividend income on the securities it holds and a Fund reports the distribution as qualified dividend income. Qualified dividend income is, in general, dividend income from taxable U.S. corporations (but generally not from U.S. REITs) and certain non-U.S. corporations (e.g., non-U.S. corporations that are not PFICs and which are incorporated in a possession of the U.S. or in certain countries with a comprehensive tax treaty with the U.S., or the stock of which is readily tradable on an established securities market in the U.S. (where the dividends are paid with respect to such stock)). Under current IRS guidance, the U.S. has appropriate comprehensive income tax treaties with the following countries: Australia, Austria, Bangladesh, Barbados, Belgium, Bulgaria, Canada, China (but not with Hong Kong, which is treated as a separate jurisdiction for U.S. tax purposes), Cyprus, the Czech Republic, Denmark, Egypt, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, India, Indonesia, Ireland, Israel, Italy, Jamaica, Japan, Kazakhstan, Latvia, Lithuania, Luxembourg, Malta, Mexico, Morocco, the Netherlands, New Zealand, Norway, Pakistan, the Philippines, Poland, Portugal, Romania, Russia, the Slovak Republic, Slovenia, South Africa, South Korea, Spain, Sri Lanka, Sweden, Switzerland, Thailand, Trinidad and Tobago, Tunisia, Turkey, Ukraine, the U.K. and Venezuela. Substitute payments received by a Fund for securities lent out by a Fund will not be qualified dividend income.

A dividend from a Fund will not be treated as qualified dividend income to the extent that: (i) the shareholder has not held the shares on which the dividend was paid for 61 days during the 121-day period that begins on the date that is 60 days before the date on which the shares become ex-dividend with respect to such dividend or a Fund fails to satisfy those holding period requirements with respect to the securities it holds that paid the dividends distributed to the shareholder (or, in the case of certain preferred stocks, the holding requirement of 91 days during the 181-day period beginning on the date that is 90 days before the date on which the stock becomes ex-dividend with respect to such dividend); (ii) a Fund or the shareholder is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to substantially similar or related property; or (iii) the shareholder elects to treat such dividend as investment income under Section 163(d)(4)(B) of the Internal Revenue Code. Dividends received by a Fund from a REIT or another RIC may be treated as qualified dividend income only to the extent the dividend distributions are attributable to qualified dividend income received by such REIT or other RIC. In addition, the Tax Act permits a direct REIT shareholder to claim a 20% “qualified business income” deduction for ordinary REIT dividends, but does not permit a RIC paying dividends attributable to such income to pass through this special treatment to its shareholders. Unless future legislation or regulations provide for a pass-through, investors in such a RIC will treat such distributions as ordinary dividend income, as under prior law, whereas a direct REIT investor would benefit from the special treatment. It is expected that dividends received by a Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income. Distributions by a Fund of its net short-term capital gains will be taxable as ordinary income.

182

during the 180 period beginning 90 days prior to ex-dividend date for certain preference dividends) during which risk of loss may not be diminished is required for the applicable shares, at both the Fund and shareholder level, for a dividend to be eligible for the dividends received deduction. Restrictions may apply if indebtedness, including a short sale, is attributable to the investment.

Excess Inclusion Income. Under current law, the Funds serve to block unrelated business taxable income (“UBTI”) from being realized by their respective tax-exempt shareholders. Notwithstanding the foregoing, a tax-exempt shareholder could realize UBTI by virtue of its investment in a Fund if shares in the Fund constitute debt-financed property in the hands of the tax-exempt shareholder within the meaning of Section 514(b) of the Internal Revenue Code. Certain types of income received by a Fund from REITs, real estate mortgage investment conduits, taxable mortgage pools or other investments may cause the Fund to report some or all of its distributions as “excess inclusion income.” To Fund shareholders, such excess inclusion income may: (i) constitute taxable income, as UBTI for those shareholders who would otherwise be tax-exempt such as individual retirement accounts, 401(k) accounts, Keogh plans, pension plans and certain charitable entities; (ii) not be offset by otherwise allowable deductions for tax purposes; (iii) not be eligible for reduced U.S. withholding for non-U.S. shareholders even from tax treaty countries; and (iv) cause the Fund to be subject to tax if certain “disqualified organizations,” as defined by the Internal Revenue Code, are Fund shareholders. If a charitable remainder annuity trust or a charitable remainder unitrust (each as defined in Section 664 of the Internal Revenue Code) has UBTI for a taxable year, a 100% excise tax on the UBTI is imposed on the trust.

Non-U.S. Investments. Under Section 988 of the Internal Revenue Code, gains or losses attributable to fluctuations in exchange rates between the time a Fund accrues income or receivables or expenses or other liabilities denominated in a non-U.S. currency and the time a Fund actually collects such income or pays such liabilities are generally treated as ordinary income or ordinary loss. In general, gains (and losses) realized on debt instruments will be treated as Section 988 gain (or loss) to the extent attributable to changes in exchange rates between the U.S. dollar and the currencies in which the instruments are denominated. Similarly, gains or losses on non-U.S. currency, non-U.S. currency forward contracts and certain non-U.S. currency options or futures contracts denominated in non-U.S. currency, to the extent attributable to fluctuations in exchange rates between the acquisition and disposition dates, are also treated as ordinary income or loss unless a Fund was to elect otherwise.

Each Fund may be subject to non-U.S. income taxes withheld at the source. Each Fund, if permitted to do so, may elect to “pass through” to its investors the amount of non-U.S. income taxes paid by the Fund provided that the Fund held the security on the dividend settlement date and for at least 15 additional days immediately before and/or thereafter, with the result that each investor with respect to shares of the Fund held for a minimum 16-day holding period at the time of deemed distribution will (i) include in gross income, even though not actually received, the investor’s pro rata share of the Fund’s non-U.S. income taxes, and (ii) either deduct (in calculating U.S. taxable income, but only for investors who itemize their deductions on their personal tax returns) or credit (in calculating U.S. federal income tax) the investor’s pro rata share of the Fund’s non-U.S. income taxes. Withholding taxes on dividends on non-U.S. securities while such securities are lent out by the Fund are not eligible for non-U.S. tax credit pass through. Taxes not “passed through” for tax purposes will not be available to shareholders for foreign tax credit purposes. A non-U.S. person invested in a Fund in a year that the Fund elects to “pass through” its non-U.S. taxes may be treated as receiving additional dividend income subject to U.S. withholding tax. A non-U.S. tax credit may not exceed the investor’s U.S. federal income tax otherwise payable with respect to the investor’s non-U.S. source income. For this purpose, shareholders must treat as non-U.S. source gross income (i) their proportionate shares of non-U.S. taxes paid by a Fund and (ii) the portion of any dividend paid by the Fund that represents income derived from non-U.S. sources; the Fund’s gain from the sale of securities will generally be treated as U.S.-source income. Certain limitations will be imposed to the extent to which the non-U.S. tax credit may be claimed. If your Fund shares are loaned pursuant to securities lending arrangements, you may lose the ability to use any non-U.S. tax credits passed through by a Fund or to treat Fund dividends (paid while the shares are held by the borrower) as qualified dividends. Regarding a short sale with respect to shares of a Fund, substitute payments made to the lender of such shares may not be deductible under certain circumstances. Consult your financial intermediary or tax advisor.

Passive Foreign Investment Companies. If a Fund purchases shares in PFICs, it may be subject to U.S. federal income tax on a portion of any “excess distribution” or gain from the disposition of such shares even if such income is distributed as a taxable dividend by the Fund to its shareholders. Additional charges in the nature of interest may be imposed on a Fund in respect of deferred taxes arising from such distributions or gains.

183

If a Fund were to invest in a PFIC and elect to treat the PFIC as a “qualified electing fund” under the Internal Revenue Code, in lieu of the foregoing requirements, a Fund might be required to include in income each year a portion of the ordinary earnings and net capital gains of the qualified electing fund, even if not distributed to a Fund, and such amounts would be subject to the 90% and excise tax distribution requirements described above. In order to make this election, a Fund would be required to obtain certain annual information from the PFICs in which it invests, which may be difficult or impossible to obtain. Currently proposed IRS regulations, if adopted, would treat such included amounts as nonqualifying RIC income to a Fund unless such amounts were also distributed to the Fund.

Alternatively, a Fund may make a mark-to-market election that would result in a Fund being treated as if it had sold and repurchased its PFIC stock at the end of each year. In such case, a Fund would report any such gains as ordinary income and would deduct any such losses as ordinary losses to the extent of previously recognized gains. The election must be made separately for each PFIC owned by a Fund and, once made, would be effective for all subsequent taxable years, unless revoked with the consent of the IRS. By making the election, a Fund could potentially ameliorate the adverse tax consequences with respect to its ownership of shares in a PFIC, but in any particular year may be required to recognize income in excess of the distributions it receives from PFICs and its proceeds from dispositions of PFIC stock. A Fund may have to distribute this “phantom” income and gain to satisfy the 90% distribution requirement and to avoid imposition of the 4% excise tax.

A Fund will make the appropriate tax elections, if possible, and take any additional steps that are necessary to mitigate the effects of these rules.

Reporting. If a shareholder recognizes a loss with respect to a Fund’s shares of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder must file with the IRS a disclosure statement on IRS Form 8886. Direct shareholders of portfolio securities are in many cases exempted from this reporting requirement, but under current guidance, shareholders of a RIC are not exempted. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer’s treatment of the loss is proper. Shareholders should consult their tax advisors to determine the applicability of these regulations in light of their individual circumstances.

Other Taxes. Dividends, distributions and redemption proceeds may also be subject to additional state, local and non-U.S. taxes depending on each shareholder’s particular situation.

Properly-reported dividends are generally exempt from U.S. federal withholding tax where they (i) are paid in respect of a Fund’s “qualified net interest income” (generally, the Fund’s U.S. source interest income, other than certain contingent interest and interest from obligations of a corporation or partnership in which the Fund is at least a 10% shareholder or partner, reduced by expenses that are allocable to such income) or (ii) are paid in respect of a Fund’s “qualified short-term capital gains” (generally, the excess of the Fund’s net short-term capital gain over the Fund’s long-term capital loss for such taxable year). However, depending on its circumstances, a Fund may report all, some or none of its potentially eligible dividends as such qualified net interest income or as qualified short-term capital gains and/or treat such dividends, in whole or in part, as ineligible for this exemption from withholding. In order to qualify for this exemption from withholding, a non-U.S. shareholder will need to comply with applicable certification requirements relating to its non-U.S. status (including, in general, furnishing an IRS Form W-8BEN, IRS Form W-8BEN-E or substitute Form). In the case of shares held through an intermediary, the intermediary may withhold even if a Fund reports the payment as qualified net interest income or qualified short-term capital gain. Non-U.S. shareholders should contact their intermediaries with respect to the application of these rules to their accounts.

184

Distributions that a Fund reports as “short-term capital gain dividends” or “long-term capital gain dividends” will not be treated as such to a recipient foreign shareholder if the distribution is attributable to gain received from the sale or exchange of U.S. real property or an interest in a U.S. real property holding corporation and the Fund’s direct or indirect interests in U.S. real property exceeded certain levels. Instead, if the foreign shareholder has not owned more than 5% of the outstanding shares of the Fund at any time during the one year period ending on the date of distribution, such distributions will be subject to 30% withholding by the Fund and will be treated as ordinary dividends to the foreign shareholder; if the foreign shareholder owned more than 5% of the outstanding shares of a Fund at any time during the one year period ending on the date of the distribution, such distribution will be treated as real property gain subject to 21% withholding tax and could subject the foreign shareholder to U.S. filing requirements. Additionally, if a Fund’s direct or indirect interests in U.S. real property were to exceed certain levels, a foreign shareholder realizing gains upon redemption from the Fund could be subject to the 21% withholding tax and U.S. filing requirements unless more than 50% of the Fund’s shares were owned by U.S. persons at such time or unless the foreign person had not held more than 5% of the Fund’s outstanding shares throughout either such person’s holding period for the redeemed shares or, if shorter, the previous five years.

185

Shares of a Fund held by a non-U.S. shareholder at death will be considered situated within the U.S. and subject to the U.S. estate tax.

Regulation Under the Alternative Investment Fund Managers Directive. The Alternative Investment Fund Managers Directive (“AIFMD”) imposes detailed and prescriptive obligations on fund managers established in the EU (“EU Operative Provisions”). These do not currently apply to managers established outside of the EU, such as BFA. Rather, non-EU managers are only required to comply with certain disclosure, reporting and transparency obligations of AIFMD (“AIFMD Disclosure Provisions”) if such managers market a fund to EU investors.

Where the AIFMD Disclosure Provisions relate to EU Operative Provisions that do not apply to BFA, no meaningful disclosure can be made. These EU Operative Provisions include prescriptive rules on: measuring and capping leverage in line with known European standards; the treatment of investors; the use of “depositaries”; and coverage for professional liability risks.

AIFMD imposes certain conditions on the marketing of funds, such as the Funds, to EU investors. AIFMD requires that an ‘alternative investment fund manager’ (“AIFM”) be identified to meet such conditions where such marketing is sought. For these purposes BFA, as the legal entity responsible for performing the portfolio and risk management of the Funds, shall be the AIFM.

186

appropriate, disclose in its annual report information on the Fund's leverage, risk profile and risk management systems employed by BFA. Each Fund will also disclose material changes, if any, to the liquidity management systems and procedures employed in respect of the Fund.

A-7

Conflicts management

•	BlackRock has adopted a proxy voting oversight structure whereby the Corporate Governance Committees oversee the voting decisions and other activities of the Corporate Governance Group, and particularly its activities with respect to voting in the relevant region of each Corporate Governance Committee’s jurisdiction.
•	The Corporate Governance Committees have adopted Guidelines for each region, which set forth the firm’s views with respect to certain corporate governance and other issues that typically arise in the proxy voting context. The Corporate Governance Committees receive periodic reports regarding the specific votes cast by the Corporate Governance Group and regular updates on material process issues, procedural changes and other matters of concern to the Corporate Governance Committees.
•	BlackRock’s Global Corporate Governance Oversight Committee oversees the Global Head, the Corporate Governance Group and the Corporate Governance Committees. The Global Corporate Governance Oversight Committee conducts a review, at least annually, of the proxy voting process to ensure compliance with BlackRock’s risk policies and procedures.
•	BlackRock maintains a reporting structure that separates the Global Head and Corporate Governance Group from employees with sales responsibilities. In addition, BlackRock maintains procedures intended to ensure that all engagements with corporate issuers or dissident shareholders are managed consistently and without regard to BlackRock’s relationship with the issuer of the proxy or dissident shareholder. Within the normal course of business, the Global Head or Corporate Governance Group may engage directly with BlackRock clients, and with employees with sales responsibilities, in discussions regarding general corporate governance policy matters, and to otherwise ensure that proxy-related client service levels are met. The Global Head or Corporate Governance Group does not discuss any specific voting matter with a client prior to the disclosure of the vote decision to all applicable clients after the shareholder meeting has taken place, except if the client is acting in the capacity as issuer of the proxy or dissident shareholder and is engaging through the established procedures independent of the client relationship.
•	In certain instances, BlackRock may determine to engage an independent fiduciary to vote proxies as a further safeguard to avoid potential conflicts of interest or as otherwise required by applicable law. The independent fiduciary may either vote such proxies or provide BlackRock with instructions as to how to vote such proxies. In the latter case, BlackRock votes the proxy in accordance with the independent fiduciary’s determination. Use of an independent fiduciary has been

A-8

adopted for voting the proxies related to any company that is affiliated with BlackRock or any company that includes BlackRock employees on its board of directors.

Appendix B - Regular Holidays and Redemptions

The securities delivery cycles currently practicable for transferring portfolio securities to redeeming investors, coupled with non-U.S. market holiday schedules, will require a delivery process longer than seven calendar days, in certain circumstances. The holidays applicable to each Fund during such periods are listed below, as are instances where more than seven days will be needed to deliver redemption proceeds. Although certain holidays may occur on different dates in subsequent years, the number of days required to deliver redemption proceeds in any given year is not expected to exceed the maximum number of days listed below for each Fund. The proclamation of new holidays, the treatment by market participants of certain days as “informal holidays” (e.g., days on which no or limited securities transactions occur, as a result of substantially shortened trading hours), the elimination of existing holidays, or changes in local securities delivery practices, could affect the information set forth herein in the future.

In calendar year 2018 (the only year for which holidays are known at the time of filing of this SAI), the dates of regular holidays affecting the relevant securities markets in which a Fund invests are as follows (please note that these holiday schedules are subject to potential changes in the relevant securities markets):

General Description of the Trust and the Funds

•	iShares Asia 50 ETF
•	iShares Emerging Markets Infrastructure ETF

•	iShares Global Healthcare ETF
•	iShares Global Materials ETF

•	iShares Global Tech ETF
•	iShares Global Timber & Forestry ETF
•	iShares India 50 ETF
•	iShares International Dividend Growth ETF
•	iShares Latin America 40 ETF

Each Fund offers and issues shares at their net asset value per share (“NAV”) only in aggregations of a specified number of shares (each, a “Creation Unit”), generally in exchange for a designated portfolio of securities (including any portion of such securities for which cash may be substituted) included in its Underlying Index (the “Deposit Securities”), together with the deposit of a specified cash payment (the “Cash Component”) (other than the iShares India 50 ETF, which currently issues Creation Units of its shares solely for cash). Shares of the Funds are listed for trading on national securities exchanges such as Cboe BZX Exchange, Inc. (“Cboe BZX”) (formerly known as BATS Exchange, Inc.), The Nasdaq Stock Market (“NASDAQ”) or NYSE Arca, Inc. (“NYSE Arca”) (each, a “Listing Exchange”). Shares of each Fund are traded in the secondary market and elsewhere at market prices that may be at, above or below the Fund's NAV. Shares are redeemable only in Creation Units by Authorized Participants (as defined in the Portfolio Holdings Information section of this SAI), and, generally, in exchange for portfolio securities and a Cash Amount (as defined in the Redemption of Creation Units section of this SAI) (other than the iShares India 50 ETF, which currently redeems Creation Units of its shares solely for cash). Creation Units typically are a specified number of shares, generally ranging from 50,000 to 250,000 shares or multiples thereof.

Exchange Listing and Trading

Shares of each Fund are listed for trading, and trade throughout the day, on the applicable Listing Exchange and in other secondary markets. Shares of each Fund may also be listed on certain non-U.S. exchanges. There can be no assurance that the requirements of the Listing Exchange necessary to maintain the listing of shares of any Fund will continue to be met. The Listing Exchange may, but is not required to, remove the shares of a Fund from listing if, among other things: (i) following the initial 12-month period beginning upon the commencement of trading of Fund shares, there are fewer than 50 record and/or beneficial owners of shares of the Fund for 30 or more consecutive trading days, (ii) the value of the Underlying Index on which a Fund is based is no longer calculated or available, or (iii) any other event shall occur or condition shall exist that, in the opinion of the Listing Exchange, makes further dealings on the Listing Exchange inadvisable. The Listing Exchange will also remove shares of a Fund from listing and trading upon termination of the Fund or in the event a Fund does not comply with the continuous listing standards of the Listing Exchange, as described in the Fund’s Prospectus.

As in the case of other publicly-traded securities, when you buy or sell shares of a Fund through a broker, you may incur a brokerage commission determined by that broker, as well as other charges.

An IOPV has an equity securities component and a cash component. The equity securities values included in an IOPV are the values of the Deposit Securities for a Fund. While the IOPV reflects the current value of the Deposit Securities required to be deposited in connection with the purchase of a Creation Unit, it does not necessarily reflect the precise composition of the current portfolio of securities held by the Funds at a particular point in time because the current portfolio of the Fund may include securities that are not a part of the current Deposit Securities. Therefore, a Fund’s IOPV disseminated during the Listing Exchange trading hours should not be viewed as a real-time update of the Fund’s NAV, which is calculated only once a day.

Investment Strategies and Risks

The iShares India 50 ETF seeks to achieve its objective by investing all its assets that are invested in Indian securities in a wholly-owned subsidiary located in the Republic of Mauritius (the “Subsidiary”). BFA serves as investment adviser to both the Fund and the Subsidiary. Unless otherwise indicated, references made in this SAI to the iShares India 50 ETF refer to the Subsidiary and/or the Fund as applicable.

Each Fund engages in representative sampling, which is investing in a sample of securities selected by BFA to have a collective investment profile similar to that of the Fund's Underlying Index. Securities selected have aggregate investment characteristics (based on market capitalization and industry weightings), fundamental characteristics (such as return variability, earnings valuation and yield) and liquidity measures similar to those of the Underlying Index. A fund that uses representative sampling generally does not hold all of the securities that are in its underlying index.

Although the Funds do not seek leveraged returns, certain instruments used by the Funds may have a leveraging effect as described below.

Borrowing. Each Fund may borrow for temporary or emergency purposes, including to meet payments due from redemptions or to facilitate the settlement of securities or other transactions. Under normal market conditions, any borrowing by a Fund (except the iShares India 50 ETF) will not exceed 10% of the Fund's net assets; however, each Fund (except the iShares India 50 ETF) generally does not intend to borrow money. iShares International Dividend Growth ETF, along with certain other iShares funds, has entered into a line of credit with State Street Bank and Trust Company (“State Street”) that may be used for temporary or emergency purposes, including redemption, settlement of trades and rebalancing of portfolio holdings.

Currency Transactions. A currency forward contract is an over-the-counter (“OTC”) obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days greater than two days from the date on which the contract is agreed upon by the parties, at a price set at the time of the contract. A non-deliverable currency forward is an OTC currency forward settled in a specified currency, on a specified date, based on the difference between the agreed-upon exchange rate and the market exchange rate. A currency futures contract is a contract that trades on an organized futures exchange involving an obligation to deliver or acquire a specified amount of a specific currency, at a specified price and at a specified future time. Currency futures contracts may be settled on a net cash payment basis rather than by the sale and delivery of the underlying currency. To the extent required by law, liquid assets committed to futures contracts will be maintained. Each Fund does not expect to engage in currency transactions for the purpose of hedging against declines in the value of the Funds' assets that are denominated in a non-U.S. currency. A Fund may enter into non-U.S. currency forward and non-U.S. currency futures transactions to facilitate local securities settlements or to protect against currency exposure in connection with its distributions to shareholders, but may not enter into such contracts for speculative purposes.

Foreign exchange transactions involve a significant degree of risk and the markets in which foreign exchange transactions are effected may be highly volatile, highly specialized and highly technical. Significant changes, including changes in liquidity and prices, can occur in such markets within very short periods of time, often within minutes. Foreign exchange trading risks include, but are not limited to, exchange rate risk, counterparty risk, maturity gap, interest rate risk, and potential interference by foreign governments through regulation of local exchange markets, foreign investment or particular transactions in non-U.S. currency. If BFA utilizes foreign exchange transactions at an inappropriate time or judges market conditions, trends or correlations incorrectly, foreign exchange transactions may not serve their intended purpose of improving the correlation of a Fund's return with the performance of its Underlying Index and may lower the Fund’s return. Each Fund could experience losses if the value of its currency forwards, options or futures positions were poorly correlated with its other investments or if it could not close out its positions because of an illiquid market or otherwise. In addition, a Fund could incur transaction costs, including trading commissions, in connection with certain non-U.S. currency transactions.

Diversification Status. The following table sets forth the diversification status of each Fund:

Diversified Funds		Non-Diversified Funds
iShares Global Healthcare ETF		iShares Asia 50 ETF
iShares Global Materials ETF		iShares Emerging Markets Infrastructure ETF
		iShares Global Tech ETF

Diversified Funds		Non-Diversified Funds
		iShares Global Timber & Forestry ETF
		iShares India 50 ETF
		iShares International Dividend Growth ETF
		iShares Latin America 40 ETF

on the futures contract. The potential for loss related to the purchase of an option on a futures contract is limited to the premium paid for the option plus transaction costs. Because the value of the option is fixed at the point of sale, there are no daily cash payments by the purchaser to reflect changes in the value of the underlying contract; however, the value of the option changes daily and that change would be reflected in the NAV of each Fund. The potential for loss related to writing call options is unlimited. The potential for loss related to writing put options is limited to the agreed-upon price per share, also known as the “strike price,” less the premium received from writing the put. Certain of the Funds may purchase and write put and call options on futures contracts that are traded on an exchange as a hedge against changes in value of their portfolio securities or in anticipation of the purchase of securities, and may enter into closing transactions with respect to such options to terminate existing positions. There is no guarantee that such closing transactions can be effected.

cash collateral and the fee paid to the borrower. In the case of collateral other than cash, a Fund is typically compensated by a fee paid by the borrower equal to a percentage of the market value of the loaned securities. Any cash collateral may be reinvested in certain short-term instruments either directly on behalf of each lending Fund or through one or more joint accounts or money market funds, including those affiliated with BFA; such investments are subject to investment risk.

Securities lending involves exposure to certain risks, including operational risk (i.e., the risk of losses resulting from problems in the settlement and accounting process), “gap” risk (i.e., the risk of a mismatch between the return on cash collateral reinvestments and the fees a Fund has agreed to pay a borrower), and credit, legal, counterparty and market risk. If a securities lending counterparty were to default, a Fund would be subject to the risk of a possible delay in receiving collateral or in recovering the loaned securities, or to a possible loss of rights in the collateral. In the event a borrower does not return a Fund’s securities as agreed, the Fund may experience losses if the proceeds received from liquidating the collateral do not at least equal the value of the loaned security at the time the collateral is liquidated, plus the transaction costs incurred in purchasing replacement securities. This event could trigger adverse tax consequences for a Fund. A Fund could lose money if its short-term investment of the collateral declines in value over the period of the loan. Substitute payments for dividends received by a Fund for securities loaned out by the Fund will not be considered qualified dividend income. BTC will take into account the tax effects on shareholders caused by this difference in connection with a Fund’s securities lending program. Substitute payments received on tax-exempt securities loaned out will not be tax-exempt income.

Non-U.S. Securities. Each Fund intends to purchase publicly-traded common stocks of non-U.S. issuers. To the extent a Fund invests in stocks of non-U.S. issuers, the Fund's investment in such stocks may be in the form of American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) and European Depositary Receipts (“EDRs”) (collectively, “depositary receipts”). Depositary receipts are receipts, typically issued by a bank or trust issuer, which evidence ownership of underlying securities issued by a non-U.S. issuer. Depositary receipts may not necessarily be denominated in the same currency as their underlying securities. ADRs typically are issued by an American bank or trust company and evidence ownership of underlying securities issued by a foreign corporation. EDRs, which are sometimes referred to as Continental Depositary Receipts, are receipts issued in Europe, typically by foreign banks and trust companies, that evidence ownership of either foreign or domestic underlying securities. GDRs are depositary receipts structured like global debt issues to facilitate trading on an international basis. Generally, ADRs, issued in registered form, are designed for use in the U.S. securities markets, and EDRs, issued in bearer form, are designed for use in European securities markets. GDRs are tradable both in the U.S. and in Europe and are designed for use throughout the world.

Depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted. In addition to investment risks associated with the underlying issuer, depositary receipts expose a Fund to additional risks associated with the non-uniform terms that apply to depositary receipt programs, credit exposure to the depository bank and to the sponsors and other parties with whom the depository bank establishes the programs, currency risk and liquidity risk. Unsponsored programs, which are not sanctioned by the issuer of the underlying common stock, generally expose investors to greater risks than sponsored programs and do not provide holders with many of the shareholder benefits that come from investing in a sponsored depositary receipts.

Investing in the securities of non-U.S. issuers involves special risks and considerations not typically associated with investing in U.S. issuers. These include differences in accounting, auditing and financial reporting standards; the possibility of expropriation or confiscatory taxation; adverse changes in investment or exchange control regulations; political instability, which could affect U.S. investments in non-U.S. countries; and potential restrictions on the flow of international capital. Non-U.S. issuers may be subject to less governmental regulation than U.S. issuers. Moreover, individual non-U.S. economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product (“GDP”), rate of inflation, capital reinvestment, resource self-sufficiency and balance of payment positions.

Regulation Regarding Derivatives. The CFTC subjects advisers to registered investment companies to regulation by the CFTC if a fund that is advised by the adviser either (i) invests, directly or indirectly, more than a prescribed level of its liquidation value in CFTC-regulated futures, options and swaps (“CFTC Derivatives”), or (ii) markets itself as providing investment exposure to such instruments. The CFTC also subjects advisers to registered investment companies to regulation by the CFTC if the registered investment company invests in one or more commodity pools. To the extent a Fund uses CFTC Derivatives, it intends to do so below such prescribed levels and intends not to market itself as a “commodity pool” or a vehicle for trading such instruments.

BFA has claimed an exclusion from the definition of the term “commodity pool operator” under the CEA pursuant to Rule 4.5 under the CEA with respect to the iShares Emerging Markets Infrastructure ETF, iShares Global Healthcare ETF, iShares Global Materials ETF, iShares Global Tech ETF, iShares Global Timber & Forestry ETF, iShares India 50 ETF and iShares International Dividend Growth ETF. BFA is not, therefore, subject to registration or regulation as a “commodity pool operator” under the CEA with respect to the Funds.

The iShares Asia 50 ETF and iShares Latin America 40 ETF (the “No-Action Letter Funds”) may also have investments in “underlying funds” (and such underlying funds themselves may invest in underlying funds) not advised by BFA (which for purposes of the no-action letter referenced below may include certain securitized vehicles, mortgage real estate investment trusts (“REITs”) and/or investment companies that may invest in CFTC Derivatives), and therefore may be viewed by the CFTC as commodity pools. BFA has no transparency into the holdings of these underlying funds because they are not advised by BFA. To address this issue of lack of transparency, the CFTC staff issued a no-action letter on November 29, 2012 permitting the advisor of a fund that invests in such underlying funds and that would otherwise have filed a claim of exclusion pursuant to CFTC Rule 4.5 to delay registration as a “commodity pool operator” until six months from the date on which the CFTC issues additional guidance on the treatment of CFTC Derivatives held by underlying funds. BFA, the advisor of the No-Action Letter Funds, has filed a claim with the CFTC for such Fund to rely on this no-action relief. Accordingly, BFA is not currently subject to registration or regulation as a “commodity pool operator” under the CEA in respect of such Fund.

entered into, are determined to (A) have exceptionally strong capacity to meet their financial obligations and (B) are sufficiently liquid such that they can be sold at approximately their carrying value in the ordinary course of business within seven days.

Reverse Repurchase Agreements. Reverse repurchase agreements involve the sale of securities with an agreement to repurchase the securities at an agreed-upon price, date and interest payment and have the characteristics of borrowing. Generally, the effect of such transactions is that a Fund can recover all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement, while in many cases the Fund is able to keep some of the interest income associated with those securities. Such transactions are advantageous only if a Fund has an opportunity to earn a rate of interest on the cash derived from these transactions that is greater than the interest cost of obtaining the same amount of cash. Opportunities to realize earnings from the use of the proceeds equal to or greater than the interest required to be paid may not always be available, and a Fund intends to use the reverse repurchase technique only when BFA believes it will be advantageous to the Fund. The use of reverse repurchase agreements may exaggerate any increase or decrease in the value of a Fund’s assets. A Fund’s exposure to reverse repurchase agreements will be covered by liquid assets having a value equal to or greater than the Fund’s obligations under such commitments. The use of reverse repurchase agreements is a form of leverage, and the proceeds obtained by a Fund through reverse repurchase agreements may be invested in additional securities.

Securities of Investment Companies. Each Fund may invest in the securities of other investment companies (including money market funds) to the extent permitted by law. Pursuant to the 1940 Act, a Fund’s investment in registered investment companies is generally limited to, subject to certain exceptions: (i) 3% of the total outstanding voting stock of any one investment company; (ii) 5% of a Fund’s total assets with respect to any one investment company; and (iii) 10% of a Fund’s total assets with respect to investment companies in the aggregate. To the extent allowed by law or regulation, each Fund intends from time to time to invest its assets in the securities of investment companies, including, but not limited to, money market funds, including those advised by or otherwise affiliated with BFA, in excess of the general limits discussed above. Other investment companies in which a Fund may invest can be expected to incur fees and expenses for operations, such as investment advisory and administration fees, which would be in addition to those incurred by the Fund. In addition, the iShares Emerging Markets Infrastructure ETF, in order to improve its portfolio liquidity and its ability to track its Underlying Index, may invest up to 10% of its assets in shares of other iShares funds that provide exposure similar to certain of the markets included in its Underlying Index. BFA has contractually agreed to waive its management fees and expenses in an amount equal to the iShares Emerging Markets Infrastructure ETF's pro rata share of the fees and expenses attributable to the Fund's investments in other iShares funds. Pursuant to guidance issued by the SEC staff, fees and expenses of money market funds used for cash collateral received in connection with loans of securities are not treated as Acquired Fund Fees and Expenses, which reflect a Fund’s pro rata share of the fees and expenses incurred by investing in other investment companies (as disclosed in the Prospectus, as applicable).

remaining maturities at the date of purchase of not more than 397 days and that have been determined to present minimal credit risks, in accordance with the requirements set forth in Rule 2a-7 under the 1940 Act; (vi) repurchase agreements; and (vii) short-term U.S. dollar-denominated obligations of non-U.S. banks (including U.S. branches) that, in the opinion of BFA, are of comparable quality to obligations of U.S. banks that may be purchased by a Fund. Any of these instruments may be purchased on a current or forward-settled basis. Time deposits are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates. Bankers’ acceptances are time drafts drawn on commercial banks by borrowers, usually in connection with international transactions.

Swap Agreements. Swap agreements are contracts between parties in which one party agrees to make periodic payments to the other party based on the change in market value or level of a specified rate, index or asset. In return, the other party agrees to make periodic payments to the first party based on the return of a different specified rate, index or asset. Swap agreements will usually be performed on a net basis, with a Fund receiving or paying only the net amount of the two payments. The net amount of the excess, if any, of a Fund’s obligations over its entitlements with respect to each swap is accrued on a daily basis, and an amount of liquid assets having an aggregate value at least equal to the accrued excess will be maintained by the Fund.

Certain of the Funds may enter into currency, interest rate or index swaps. The use of currency, interest rate and index swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. These transactions generally do not involve the delivery of securities or other underlying assets.

General Considerations and Risks

A discussion of some of the principal risks associated with an investment in a Fund is contained in the applicable Prospectus.

An investment in a Fund should be made with an understanding that the value of the Fund’s portfolio securities may fluctuate in accordance with changes in the financial condition of the issuers of the portfolio securities, the value of stocks in general, and other factors that affect the market.

other factors, could result in ownership registration being lost. In addition, the laws of certain countries may put limits on a Fund’s ability to recover its assets if a foreign bank or depository or issuer of a security or an agent of any of the foregoing goes bankrupt. A Fund would absorb any loss resulting from such custody problems and may have no successful claim for compensation.

Dividend-Paying Stock Risk. A Fund's strategy of investing in dividend-paying stocks involves the risk that such stocks may fall out of favor with investors and underperform the market. Companies that issue dividend-paying stocks are not required to continue to pay dividends on such stocks. Therefore, there is the possibility that such companies could reduce or eliminate the payment of dividends in the future or the anticipated acceleration of dividends may not occur. Depending upon market conditions, dividend-paying stocks that meet the Fund’s investment criteria may not be widely available and/or may be highly concentrated in only a few market sectors.

Operational Risk. BFA and a Fund's other service providers may experience disruptions or operating errors such as processing errors or human errors, inadequate or failed internal or external processes, or systems or technology failures, that could negatively impact the Funds. While service providers are required to have appropriate operational risk management policies and procedures, their methods of operational risk management may differ from a Fund’s in the setting of priorities, the personnel and resources available or the effectiveness of relevant controls. BFA, through its monitoring and oversight of service providers, seeks to ensure that service providers take appropriate precautions to avoid and mitigate risks that could lead to disruptions and operating errors. However, it is not possible for BFA or the other Fund service providers to identify all of the operational risks that may affect a Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects.

Risk of Derivatives. A derivative is a financial contract, the value of which depends on, or is derived from, the value of an underlying asset, such as a security, a commodity (such as gold or silver), a currency or an index (a measure of value or rates, such as the S&P 500^® or the prime lending rate). A Fund may invest in futures contracts, securities options and other derivatives. Compared to conventional securities, derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices and thus a Fund’s losses may be greater if it invests in derivatives than if it invests only in conventional securities. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations. Derivatives generally involve the incurrence of leverage. To address such leverage and to prevent a Fund from being deemed to have issued senior securities as a result of an investment in derivatives, such Fund will segregate liquid assets equal to its obligations under the derivatives throughout the life of the investment.

When a derivative is used as a hedge against a position that a Fund holds or is committed to purchase, any loss generated by the derivative generally should be substantially offset by gains on the hedged investment, and vice versa. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains and, in some cases, hedging can cause losses that are not offset by gains, and a Fund will recognize losses on both the investment and the hedge. Hedges are sometimes subject to imperfect matching between the derivative and the underlying security, and there can be no assurance that a Fund's hedging transactions, which entail additional transaction costs, will be effective.

Risk of Futures and Options on Futures Transactions. There are several risks accompanying the utilization of futures contracts and options on futures contracts. A position in futures contracts and options on futures contracts may be closed only on the exchange on which the contract was made (or a linked exchange). While each Fund plans to utilize futures contracts only if an active market exists for such contracts, there is no guarantee that a liquid market will exist for the contract at a specified time. Futures contracts, by definition, project price levels in the future and not current levels of valuation; therefore, market circumstances may result in a discrepancy between the price of the future and the movement in a Fund's Underlying Index. In the event of adverse price movements, a Fund would continue to be required to make daily cash payments to maintain its required margin. In such situations, if a Fund has insufficient cash, it may have to sell portfolio securities to meet daily margin requirements at a time when it may be disadvantageous to do so. In addition, a Fund may be required to deliver the instruments underlying the futures contracts it has sold.

The risk of loss in trading futures contracts or uncovered call options in some strategies (e.g., selling uncovered stock index futures contracts) is potentially unlimited. The Funds do not plan to use futures and options contracts in this way. The risk of a futures position may still be large as traditionally measured due to the low margin deposits required. In many cases, a relatively small price movement in a futures contract may result in immediate and substantial loss or gain to the investor relative to the size of a required margin deposit. The Funds, however, intend to utilize futures and options contracts in a manner designed to limit their risk exposure to levels comparable to a direct investment in the types of stocks in which they invest.

futures positions and subjecting each Fund to substantial losses. In the event of adverse price movements, each Fund would be required to make daily cash payments of variation margin.

Risk of Investing in Non-U.S. Equity Securities. An investment in each Fund involves risks similar to those of investing in portfolios of equity securities traded on non-U.S. exchanges. These risks include market fluctuations caused by such factors as economic and political developments in those foreign countries, changes in interest rates and perceived trends in stock prices. Investing in securities issued by issuers domiciled in countries other than the domicile of the investor and denominated in currencies other than an investor’s local currency entails certain considerations and risks not typically encountered by the investor in making investments in its home country and in that country’s currency. These considerations include favorable or unfavorable changes in interest rates, currency exchange rates, exchange control regulations and the costs that may be incurred in connection with conversions between various currencies. Investing in the Funds also involves certain risks and considerations not typically associated with investing in a fund whose portfolio contains exclusively securities of U.S. issuers. These risks include generally less liquid and less efficient securities markets; generally greater price volatility; less publicly available information about issuers; the imposition of withholding or other taxes; the imposition of restrictions on the expatriation of funds or other assets of the Funds; in the case of the iShares India 50 ETF, restrictions on ownership of Indian and other foreign countries' securities by foreign entities; higher transaction and custody costs; delays and risks attendant in settlement procedures; difficulties in enforcing contractual obligations; lower liquidity and significantly smaller market capitalization; different accounting and disclosure standards; lower levels of regulation of the securities markets; more substantial government interference with the economy and businesses; higher rates of inflation; greater social, economic, and political uncertainty; the risk of nationalization or expropriation of assets; and the risk of war.

Treaty/Tax Risk. The iShares India 50 ETF operates, in part, through the Subsidiary, which in turn invests in securities of Indian issuers. The Subsidiary should be eligible to take advantage of the benefits of the Double Tax Avoidance Agreement between India and Mauritius (“DTAA”) in relation to investments in shares made until March 31, 2017. Numerous investors have relied on the benefits of the DTAA to invest in India through Mauritius in the past.

An investor is required to submit the tax residency certificate (“TRC”) as issued in the country of residence and provide other documents and information as prescribed by the Government of India to claim benefits under the DTAA.

Under the DTAA, India has right to tax capital gains that arise from alienation of shares of an Indian company acquired by a Mauritian tax resident. However, the DTAA provides for grandfathering of investments in shares made before April 1, 2017. Returns from investments in shares made on or after April 1, 2017 are subject to capital gains tax in India, although the DTAA provides for a limitation of benefits provision which shall be a prerequisite for a reduced rate of tax (50% of domestic tax rate) on capital gains arising during a two year transition period from April 1, 2017 to March 31, 2019. The application of such provisions of the DTAA could result in the imposition of withholding and capital gains taxes and/or other taxes on the Subsidiary by tax authorities in India. This could significantly reduce the return to the iShares India 50 ETF on its investments in shares and the return received by the Fund’s shareholders.

Criteria for Residence of Companies in India.

A foreign company will be considered a resident in India if its place of effective management (“POEM”) (defined as a place where key management and commercial decisions that are necessary for the conduct of the business of an entity as a whole are in substance made) is in India in the relevant financial year. This test is to be applied taking the relevant financial year as a whole into consideration. The Central Board of Direct Taxes (“CBDT”) has clarified that the provisions of POEM shall not apply to a company having turnover of INR 500 million or less in a year.

Indirect Transfers.

The Income Tax Act, 1961 (“IT Act”) imposes Indian tax and withholding obligations with respect to the transfer of shares and interest in an overseas company that derives its value substantially from assets situated in India (“indirect transfers”). It has been clarified that Indian tax authorities will not reopen any assessment proceedings that were completed before April 1, 2012 and where no notice for reassessment has been issued prior to that date. It has also been clarified that any assessment or any other order which stands validated due to the amendments in the Finance Act would be enforced. Given this clarification issued by the CBDT, the iShares India 50 ETF does not expect that their respective shareholders or each Fund will become subject to tax or to withholding obligations with respect to completed assessments.

It has been clarified that the share or interest of the foreign entity shall be deemed to derive its value substantially from the assets located in India, if the value of such Indian assets exceeds INR 100 million, and represents at least 50% of the value of all the assets owned by the foreign entity. The value of an asset shall be the fair market value as of the specified date, of such an asset without reduction of liabilities. The fair market value will be determined in accordance with the final Rule 11UB of the Income Tax Rules, 1962 (“IT Rules”). It has also been provided that where all the assets of the foreign entity are not located in India, only such part of the income as is reasonably attributable to the Indian assets shall be subject to capital gains tax in India. The indirect transfer shall not be applicable in following cases:

•

If the gains arising from transfer of share or interest in a foreign entity are taxable in India in accordance with the aforementioned provisions of indirect transfer, the purchaser of the securities will be required to withhold applicable Indian taxes.

Gains realized when a non-resident acquires shares of a foreign company from another non-resident and the foreign company derives “substantial value” from Indian assets, (meaning that the value of Indian assets (i) exceeds INR 100 million, and (ii) represents at least 50% of the value of the company’s assets), such gains are taxable in India and subject to withholding, to the extent that they are reasonably attributable to the Indian assets.

Because the iShares India 50 ETF invests in Indian securities through the Subsidiary, the Subsidiary or the iShares India 50 ETF may be considered to derive “substantial value” from Indian assets. Accordingly, shareholder redemptions of the iShares India 50 ETF shares and sales of the iShares India 50 ETF shares may have been subject to Indian tax and withholding obligations. The IT Act provides for an exemption to shareholders in Category I and Category II foreign portfolio investors (“FPI”) from the applicability of indirect transfer taxation. The Subsidiary is a Category II FPI. Therefore, any redemptions or transfers by the iShares India 50 ETF or the shareholders in the iShares India 50 ETF should not be subject to Indian indirect transfer tax.

The IT Act further provides that aforesaid indirect transfer provisions will not apply to foreign investors making an investment directly or indirectly in a Securities and Exchange Board of India (“SEBI”) registered Category I and Category II foreign portfolio investor.

General Anti-Avoidance Rules.

The current legislation provides for the general anti-avoidance rules (“GAAR”) to curb aggressive tax planning with the use of sophisticated structures. CBDT has clarified that where a FPI (such as the Subsidiary) is located in a particular jurisdiction based on non-tax commercial reasons and the main purpose of the choice of location/residence of the FPI is not to obtain a treaty benefit, the GAAR provisions will not be resorted to by the tax authorities.

•	creates rights, or obligations, which are not ordinarily created between persons dealing at arm's length;
•	results, directly or indirectly, in the misuse, or abuse, of the provisions of IT Act;
•	lacks commercial substance; or
•	is entered into, or carried out, by means, or in a manner, which are not ordinarily employed for bona fide purposes.

As per the provisions of IT Rules, GAAR shall not apply in the following circumstances:

•	any arrangement where the aggregate tax benefit to all the parties of the arrangement in the relevant financial year does not exceed INR 30 Million;
•	foreign institutional investors (“FIIs”) that choose not to take any benefit under any tax treaty entered with India and has invested in listed or unlisted securities with prior permission of the competent authority in accordance with the applicable regulations;
•	non-resident investor in an FII who has invested in an FII, directly or indirectly, by way of an offshore derivative instrument or otherwise; or

•	any income derived from the transfer of shares or interests made prior to April 1, 2017.

GAAR may, irrespective of existing treaty provisions, lead to the imposition of tax liabilities and withholding obligations, and may lead the iShares India 50 ETF to modify the structure.

Indian Minimum Alternate Tax.

Recent amendments to the DTAA and GAAR could change the manner in which the Subsidiary is currently taxed in India and could adversely impact the returns to the iShares India 50 ETF/Subsidiary and their shareholders. The iShares India 50 ETF will continue to monitor developments in India with respect to these matters. Investors are urged to consult their own tax advisers with respect to their own tax situations and the tax consequences of an investment in the iShares India 50 ETF.

Risk of Investing in Mid-Capitalization Companies. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies, and, therefore, a Fund’s share price may be more volatile than that of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it more difficult for the Funds to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments.

financially stable than larger, more established companies and may depend on a small number of essential personnel, making them more vulnerable to loss of personnel. Small-capitalization companies also normally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments concerning their products.

Risk of Investing in Africa. Investments in securities of issuers in certain African countries involve heightened risks including, among others, expropriation and/or nationalization of assets, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision-making, armed conflict, civil war, and social instability as a result of religious, ethnic and/or socio-economic unrest or widespread outbreaks of disease and, in certain countries, genocidal warfare.

Certain countries in Africa generally have less developed capital markets than traditional emerging market countries, and, consequently, the risks of investing in foreign securities are magnified in such countries. Because securities markets of countries in Africa are generally underdeveloped and are generally less correlated to global economic cycles than those markets located in more developed countries, securities markets in African countries are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations and uncertainty regarding the existence of trading markets. Moreover, trading on African securities markets may be suspended altogether.

Market volatility may also be heightened by the actions of a small number of investors. Brokerage firms in certain countries in Africa may be fewer in number and less established than brokerage firms in more developed markets. Since a Fund may need to effect securities transactions through these brokerage firms, the Fund is subject to the risk that these brokerage firms will not be able to fulfill their obligations to the Fund (i.e., counterparty risk). This risk is magnified to the extent that a Fund effects securities transactions through a single brokerage firm or a small number of brokerage firms.

Certain governments in African countries restrict or control to varying degrees the ability of foreign investors to invest in securities of issuers located or operating in those countries. Moreover, certain countries in Africa require governmental approval or special licenses prior to investment by foreign investors and may limit the amount of investment by foreign investors in a particular industry and/or issuer, and may limit such foreign investment to a certain class of securities of an issuer that may have less advantageous rights than the classes available for purchase by domestic investors of the countries and/or impose additional taxes on foreign investors. A delay in obtaining a government approval or a license would delay investments in a particular country, and, as a result, a Fund may not be able to invest in certain securities while approval is pending. The government of a particular country may also withdraw or decline to renew a license that enables a Fund to invest in such country. These factors make investing in issuers located or operating in countries in Africa significantly riskier than investing in issuers located or operating in more developed countries, and any one of these factors could cause a decline in the value of a Fund’s investments. Issuers located or operating in countries in Africa are generally not subject to the same rules and regulations as issuers located or operating in more developed countries. Therefore, there may be less financial and other information publicly available with regard to issuers located or operating in countries in Africa and such issuers are generally not subject to the uniform accounting, auditing and financial reporting standards applicable to issuers located or operating in more developed countries.

In addition, governments of certain countries in Africa in which a Fund may invest may levy withholding or other taxes on income such as dividends, interest and realized capital gains. Although in certain countries in Africa a portion of these taxes are recoverable, the non-recovered portion of foreign withholding taxes will reduce the income received from investments in such countries.

Investment in countries in Africa may be subject to a greater degree of risk associated with governmental approval in connection with the repatriation of investment income, capital or the proceeds of sales of securities by foreign investors. In addition, there is the risk that if an African country’s balance of payments declines, such African country may impose temporary restrictions on foreign capital remittances. Consequently, a Fund could be adversely affected by delays in, or a refusal to grant, required governmental approval for repatriation of capital, as well as by the application to the Fund of any restrictions on investments. Additionally, investments in countries in Africa may require a Fund to adopt special procedures, seek local government approvals or take other actions, each of which may involve additional costs to the Fund.

Securities laws in many countries in Africa are relatively new and unsettled and, consequently, there is a risk of rapid and unpredictable change in laws regarding foreign investment, securities regulation, title to securities and shareholder rights. Accordingly, foreign investors may be adversely affected by new or amended laws and regulations. In addition, there may be no single centralized securities exchange on which securities are traded in certain countries in Africa and the systems of

corporate governance to which issuers located in countries in Africa are subject may be less advanced than those systems to which issuers located in more developed countries are subject, and, therefore, shareholders of issuers located in such countries may not receive many of the protections available to shareholders of issuers located in more developed countries. Even in circumstances where adequate laws and shareholder rights exist, it may not be possible to obtain swift and equitable enforcement of the law. In addition, the enforcement of systems of taxation at federal, regional and local levels in countries in Africa may be inconsistent and subject to sudden change.

Certain countries in Africa may be heavily dependent upon international trade and, consequently, have been and may continue to be negatively affected by trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which they trade. These countries also have been and may continue to be adversely affected by economic conditions in the countries with which they trade. Certain countries in Africa depend to a significant extent upon exports of primary commodities such as gold, silver, copper and diamonds. These countries therefore are vulnerable to changes in commodity prices, which may be affected by a variety of factors. In addition, certain issuers located in countries in Africa in which a Fund invests may operate in, or have dealings with, countries subject to sanctions and/or embargoes imposed by the U.S. government and the United Nations, and/or countries identified by the U.S. government as state sponsors of terrorism. As a result, an issuer may sustain damage to its reputation if it is identified as an issuer which operates in, or has dealings with, such countries. A Fund, as an investor in such issuers, will be indirectly subject to those risks.

The governments of certain countries in Africa may exercise substantial influence over many aspects of the private sector and may own or control many companies. Future government actions could have a significant effect on the economic conditions in such countries, which could have a negative impact on private sector companies. There is also the possibility of diplomatic developments that could adversely affect investments in certain countries in Africa. Some countries in Africa may be affected by a greater degree of public corruption and crime, including organized crime.

Recent political instability and protests in North Africa and the Middle East have caused significant disruptions to many industries. In addition, the outbreak of Ebola in Western Africa severely challenged health care industries in those countries and adversely impacted the region’s economy due to quarantines and disruptions of trade, which has further increased instability in the region. This instability has demonstrated that political and social unrest can spread quickly through the region, and that developments in one country can influence the political events in neighboring countries. Some protests have turned violent, and civil war and political reconstruction in certain countries such as Libya, Iraq and Syria pose a risk to investments in the region. Continued political and social unrest in these regions, including the ongoing warfare and terrorist activities in the Middle East and Africa, may negatively affect the value of an investment in a Fund.

the economic conditions in this region, which in turn could have a negative impact on private sector companies. There is also the possibility of diplomatic developments adversely affecting investments in the region.

Risk of Investing in Brazil. Investment in securities of companies domiciled in Brazil involves a high degree of risk and special considerations not typically associated with investing in the U.S. securities markets. Such heightened risks include, among others, a high level of price volatility in the Brazilian equity and currency markets, chronic structural public sector deficits, a rising unemployment rate and disparities of wealth.

Brazil has historically experienced high rates of inflation and may continue to do so in the future. An increase in prices for commodities, the depreciation of the Brazilian currency (the real) and potential future governmental measures seeking to maintain the value of the real in relation to the U.S. dollar, may trigger increases in inflation in Brazil and may slow the rate of growth of the Brazilian economy. Inflationary pressures also may limit the ability of certain Brazilian issuers to access foreign financial markets and may lead to further government intervention in the economy, including the introduction of government policies that may adversely affect the overall performance of the Brazilian economy, which in turn could adversely affect a Fund's investments.

The Brazilian government has exercised, and continues to exercise, significant influence over the Brazilian economy, which may have significant effects on Brazilian companies and on market conditions and prices of Brazilian securities. The Brazilian economy has been characterized by frequent, and occasionally drastic, intervention by the Brazilian government. The Brazilian government has often changed monetary, taxation, credit, tariff and other policies to influence the core of Brazil’s economy. The Brazilian government’s actions to control inflation and affect other economic policies have involved, among others, the setting of wage and price controls, blocking access to bank accounts, fluctuation of the base interest rates, imposing exchange controls and limiting imports into Brazil. In the past, the Brazilian government has maintained domestic price controls, and no assurances can be given that price controls will not be re-imposed in the future.

Investments in Brazilian securities may be subject to certain restrictions on foreign investment. Brazilian law provides that whenever a serious imbalance in Brazil’s balance of payments exists or is anticipated, the Brazilian government may impose temporary restrictions on the remittance to foreign investors of the proceeds of their investment in Brazil and on the conversion of Brazilian currency into foreign currency. The likelihood of such restrictions may be affected by the extent of Brazil’s foreign currency reserves, the size of Brazil’s debt service burden relative to the economy as a whole, and political constraints to which Brazil may be subject. There can be no assurance that the Brazilian government will not impose

restrictions or restrictive exchange control policies in the future, which could have the effect of preventing or restricting access to foreign currency.

The market for Brazilian securities is directly influenced by the flow of international capital, and economic and market conditions of certain countries, especially other emerging market countries in Central and South America. Adverse economic conditions or developments in other emerging market countries have at times significantly affected the availability of credit in the Brazilian economy and resulted in considerable outflows of funds and declines in the amount of foreign currency invested in Brazil. Crises in neighboring emerging market countries also may increase investors’ risk aversion, which may adversely impact the market value of the securities issued by Brazilian companies, including securities in which a Fund may invest.

with respect to such matters as insider trading rules, tender offer regulation, stockholder proxy requirements and the requirements mandating timely and accurate disclosure of information. Stock markets in China are in the process of change and further development. This may lead to trading volatility, difficulty in the settlement and recording of transactions and difficulty in interpreting and applying the relevant regulation.

While the Chinese economy has experienced past periods of rapid growth, there is no assurance that such growth rates will recur. China may experience substantial rates of inflation or economic recessions, causing a negative effect on the economy and securities market. China’s economy is heavily dependent on export growth. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers, including as a result of heightened trade tensions between China and the U.S., or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the securities of Chinese issuers.

The tax laws and regulations in the People’s Republic of China (“PRC”) are subject to change, including the issuance of authoritative guidance or enforcement, possibly with retroactive effect. The interpretation, applicability and enforcement of such laws by PRC tax authorities are not as consistent and transparent as those of more developed nations, and may vary over time and from region to region. The application and enforcement of PRC tax rules could have a significant adverse effect on a Fund and its investors, particularly in relation to capital gains withholding tax imposed upon non-residents. In addition, the accounting, auditing and financial reporting standards and practices applicable to Chinese companies may be less rigorous, and may result in significant differences between financial statements prepared in accordance with the PRC accounting standards and practice and those prepared in accordance with international accounting standards.

Risk of Investing in the Chinese Equity Markets. Certain Funds may invest in H-shares (securities of companies incorporated in the PRC that are denominated in Hong Kong dollars and listed on the Stock Exchange of Hong Kong (“SEHK”)) and/or B-shares (securities of companies incorporated in the PRC that are denominated in U.S. dollars (in the case of the Shanghai Stock Exchange (“SSE”)) or Hong Kong dollars (in the case of the Shenzhen Stock Exchange (“SZSE”)) and listed on the SSE and the SZSE). Certain Funds may also invest in certain Hong Kong listed securities known as Red-Chips (securities issued by companies incorporated in certain foreign jurisdictions, which are controlled, directly or indirectly, by entities owned by the national government or local governments in the PRC and derive substantial revenues or allocate substantial assets in the PRC) and P-Chips (securities issued by companies incorporated in certain foreign jurisdictions, which are controlled, directly or indirectly, by individuals in the PRC and derive substantial revenues or allocate substantial assets in the PRC).

many developed countries and their perceived inability to continue to service high debt loads without simultaneously implementing stringent austerity measures. Such concerns have led to tremendous downward pressure on the economies of these countries. As a result, it is possible that interest rates on debt of certain developed countries may rise to levels that make it difficult for such countries to service such debt. Spending on health care and retirement pensions in most developed countries has risen dramatically over the last few years. Medical innovation, extended life expectancy and higher public expectations are likely to continue the increase in health care and pension costs. Any increase in health care and pension costs will likely have a negative impact on the economic growth of many developed countries. Certain developed countries rely on imports of certain key items, such as crude oil, natural gas, and other commodities. As a result, an increase in demand for, or price fluctuations of, certain commodities may negatively affect developed country economies. Developed market countries generally are dependent on the economies of certain key trading partners. Changes in any one economy may cause an adverse impact on several developed countries. In addition, heavy regulation of, among others, labor and product markets may have an adverse effect on certain issuers. Such regulations may negatively affect economic growth or cause prolonged periods of recession. Such risks, among others, may adversely affect the value of a Fund’s investments.

Risk of Investing in Eastern Europe. Investing in the securities of issuers located or operating in Eastern Europe is highly speculative and involves risks not usually associated with investing in the more developed markets of Western Europe. Political and economic reforms are too recent to establish a definite trend away from centrally planned economies and state-owned industries. In the past, some Eastern European governments have expropriated substantial amounts of private property, and many claims of the property owners have never been fully settled.

Many Eastern European countries continue to move toward market economies at different paces with different characteristics. Most Eastern European securities markets suffer from thin trading activity, dubious investor protections, and often a dearth of reliable corporate information. Information and transaction costs, differential taxes, and sometimes political or transfer risk give a comparative advantage to the domestic investor rather than the foreign investor. In addition, these markets are particularly sensitive to social, political, economic, and currency events in Russia and may suffer heavy losses as a result of their trading and investment links to the Russian economy and currency. Russia also may attempt to assert its influence in the region through economic or even military measures, as it did with Georgia in the summer of 2008 and Ukraine beginning in 2014. Eastern European economies may also be particularly susceptible to changes in the international credit markets due to their reliance on bank related inflows of capital. The global economic crisis has restricted international credit supplies, and several Eastern European economies have faced significant credit and economic crises. Although some Eastern European economies are expanding again, major challenges are still present as a result of their continued dependence on the Western European zone for credit.

trades of a size customarily undertaken by institutional investors in the securities markets of developed countries. The limited size of many of these securities markets can cause prices to be erratic for reasons apart from factors that affect the soundness and competitiveness of the securities issuers. For example, prices may be unduly influenced by traders who control large positions in these markets. Additionally, market making and arbitrage activities are generally less extensive in such markets, which may contribute to increased volatility and reduced liquidity of such markets. The limited liquidity of emerging market country securities may also affect a Fund's ability to accurately value its portfolio securities or to acquire or dispose of securities at the price and time it wishes to do so or in order to meet redemption requests.

Many emerging market countries lack the social, political, and economic stability characteristic of the U.S. Political instability among emerging market countries can be common and may be caused by an uneven distribution of wealth, social unrest, labor strikes, civil wars, and religious oppression. Economic instability in emerging market countries may take the form of: (i) high interest rates; (ii) high levels of inflation, including hyperinflation; (iii) high levels of unemployment or underemployment; (iv) changes in government economic and tax policies, including confiscatory taxation; and (v) imposition of trade barriers.

recession in an EU member state may have a significant adverse effect on the economies of EU member states and their trading partners. Although certain European countries do not use the euro, many of these countries are obliged to meet the criteria for joining the euro zone. Consequently, these countries must comply with many of the restrictions noted above. The European financial markets have experienced volatility and adverse trends in recent years due to concerns about economic downturns, rising government debt levels and the possible default of government debt in several European countries, including, but not limited to, Cyprus, France, Greece, Ireland, Italy, Portugal, Spain and Ukraine. In order to prevent further economic deterioration, certain countries, without prior warning, can institute “capital controls.” Countries may use these controls to restrict volatile movements of capital entering and exiting their country. Such controls may negatively affect a Fund’s investments. A default or debt restructuring by any European country would adversely impact holders of that country’s debt and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed above. In addition, the credit ratings of certain European countries were recently downgraded. These downgrades may result in further deterioration of investor confidence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including countries that do not use the euro and non-EU member states. Responses to the financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest and may limit future growth and economic recovery or have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. The impact of these actions, especially if they occur in a disorderly fashion, is not clear but could be significant and far-reaching and could adversely impact the value of a Fund’s investments in the region. In a referendum held on June 23, 2016, the United Kingdom (the “U.K.”) resolved to leave the EU. The referendum may introduce significant uncertainties and instability in the financial markets as the U.K. negotiates its exit from the EU. Although the precise timeframe for the U.K.’s withdrawal is uncertain, on March 29, 2017, the U.K. initiated the withdrawal process by sending a formal notice of the country’s intention to withdraw from the EU. An agreement has been reached between the U.K. and the EU to continue negotiations on the U.K.’s exit from the EU. The outcome of negotiations remains uncertain. Secessionist movements, such as in Scotland or the Catalan movement in Spain, as well as governmental or other responses to such movements, may also create instability and uncertainty in the region. The occurrence of terrorist incidents throughout Europe also could impact financial markets. The impact of these events is not clear but could be significant and far-reaching and could adversely affect the value and liquidity of a Fund's investments.

Risk of Investing in India. India is an emerging market and demonstrates significantly higher volatility from time to time in comparison to more developed markets. Political, religious, and border disputes persist in India. India has recently experienced and may continue to experience civil unrest and hostilities with certain of its neighboring countries, including Pakistan, and the Indian government has confronted separatist movements in several Indian states, including Kashmir. Government control over the economy, currency fluctuations or blockage, and the risk of nationalization or expropriation of assets offer higher potential for losses. Governmental actions could have a negative effect on the economic conditions in India, which could adversely affect the value and liquidity of investments made by a Fund. The securities markets in India are comparatively underdeveloped and with some exceptions, consist of a small number of listed companies with small market capitalization, greater price volatility and substantially less liquidity than companies in more developed markets. Stockbrokers and other intermediaries in India may not perform as well as their counterparts in the U.S. or other, more developed countries. The limited liquidity of the Indian securities markets may also affect a Fund’s ability to acquire or dispose of securities at the price or time that it desires or the Fund’s ability to track its Underlying Index.

Global factors and foreign actions may inhibit the flow of foreign capital on which India is dependent to sustain its growth. In addition, the Reserve Bank of India has imposed limits on foreign ownership of Indian companies, which may decrease the liquidity of a Fund’s portfolio and result in extreme volatility in the prices of Indian securities. In November 2016, the Indian government eliminated certain large denomination cash notes as legal tender, causing uncertainty in certain financial markets. These factors, coupled with the lack of extensive accounting, auditing and financial reporting standards and practices, as applicable in the U.S., may increase the risk of loss for a Fund.

Securities laws in India are relatively new and unsettled and, as a result, there is a risk of significant and unpredictable change in laws governing foreign investment, securities regulation, title to securities and shareholder rights. Foreign investors in particular may be adversely affected by new or amended laws and regulations. Certain Indian regulatory approvals, including approvals from SEBI, the central government and the tax authorities (to the extent that tax benefits need to be utilized), may be required before a Fund can make investments in Indian companies. Capital gains from Indian securities may be subject to local taxation.

Technology and software sectors represent a significant portion of the total capitalization of the Indian securities markets. The value of these companies will generally fluctuate in response to technological and regulatory developments, and, as a result, a Fund’s holdings are expected to experience correlated fluctuations.

Natural disasters, such as tsunamis, flooding or droughts, could occur in India or surrounding areas and could negatively affect the Indian economy or operations of a Subsidiary, and, in turn, could negatively affect a Fund.

Risk of Investing in Latin America. A number of Latin American countries are among the largest debtors of developing countries and have a long history of foreign debt and default. In 2001, Argentina defaulted on its debt and many investors suffered significant losses.

The majority of the region's economies have become highly dependent upon foreign credit and loans from external sources to fuel their state-sponsored economic plans. Historically, government profligacy and ill-conceived plans for modernization have exhausted these resources with little benefit accruing to the economy. Most countries have been forced to restructure their loans or risk default on their debt obligations. In addition, interest on the debt is subject to market conditions and may reach levels that would impair economic activity and create a difficult and costly environment for borrowers. Accordingly, these governments may be forced to reschedule or freeze their debt repayment, which could negatively affect local markets. Because of their dependence on foreign credit and loans, a number of Latin American economies face significant economic difficulties and some economies fell into recession as the recent global economic crisis tightened international credit supplies. While the region has recently shown signs of economic improvement, recovery from past economic downturns in Latin America has historically been slow, and any such recovery, if sustained, may be gradual.

Substantial limitations may exist in certain Latin American countries with respect to a Fund’s ability to repatriate investment income, capital or the proceeds of sales of securities. A Fund could be adversely affected by delays in, or a refusal to grant, any required governmental approval for repatriation of capital, as well as by the application to the Fund of any restrictions on investments and difficulties in enforcing legal judgments in non-U.S. courts. Legal remedies available to investors in certain Latin American countries may be less extensive than those available to investors in the U.S. or other countries. In addition, certain Latin American countries may have legal systems that may make it difficult for the Fund to vote proxies, exercise shareholder rights, and pursue legal remedies with respect to its investments. In the past, many Latin American countries have experienced substantial, and in some periods extremely high, rates of inflation for many years. For companies that keep accounting records in the local currency, inflation accounting rules in some Latin American countries require, for both tax and accounting purposes, that certain assets and liabilities be restated on the company’s balance sheet in order to express items in terms of currency of constant purchasing power. Inflation accounting may indirectly generate losses or profits for certain Latin American companies.

Certain Latin American countries have entered into regional trade agreements that are designed to, among other things, reduce barriers between countries, increase competition among companies and reduce government subsidies in certain industries. No assurance can be given that these changes will be successful in the long term, or that these changes will result in the economic stability intended. There is a possibility that these trade arrangements will not be fully implemented, or will be partially or completely unwound. It is also possible that a significant participant could choose to abandon a trade agreement, which could diminish its credibility and influence. Any of these occurrences could have adverse effects on the markets of both participating and non-participating countries, including sharp appreciation or depreciation of participants’ national currencies and a significant increase in exchange rate volatility, a resurgence in economic protectionism, an undermining of confidence in the Latin American markets, an undermining of Latin American economic stability, the collapse or slowdown of the drive towards Latin American economic unity, and/or reversion of the attempts to lower government debt and inflation rates that were introduced in anticipation of such trade agreements. Such developments could have an adverse impact on a Fund’s investments in Latin America generally or in specific countries participating in such trade agreements.

Risk of Investing in Mexico. Investment in Mexican issuers involves risks that are specific to Mexico, including regulatory, political, and economic risks. In the past, Mexico has experienced high interest rates, economic volatility, significant devaluation of its currency (the peso), and high unemployment rates. The Mexican economy, among other things, is dependent upon external trade with other economies, specifically with the U.S. and certain Latin American countries. Recent political developments in the U.S. have potential implications for the current trade arrangements between the U.S. and Mexico, which could negatively affect the value of securities held by a Fund.

As a result, Mexico is dependent on, among other things, the U.S. economy and the economies of other Central and South American countries, and any change in the price or demand for Mexican exports may have an adverse impact on the Mexican economy. Because commodities such as oil and gas, minerals and metals represent a large portion of the region’s exports, the economies of these countries are particularly sensitive to fluctuations in commodity prices. For example, lower prices have negatively impacted Petróleos Mexicanos, the Mexican state-owned petroleum company, which accounts for approximately 30% of the Mexican government’s revenue.

Mexico’s economy has become increasingly oriented toward manufacturing, including electronic equipment and machinery, in the years since the North American Free Trade Agreement (“NAFTA”) entered into force. As Mexico’s top export is automotive vehicles, its economy is strongly tied to the U.S. automotive market, and changes to certain segments in the U.S. market could have an impact on the Mexican economy. The automotive industry and other industrial products can be highly cyclical, and companies in these industries may suffer periodic operating losses. These industries can be significantly affected by labor relations and fluctuating component prices.

The agricultural and mining sectors of Mexico’s economy also account for a large portion of its exports; Mexico is therefore susceptible to fluctuations in the price and demand for agricultural products and natural resources. In addition, Mexico has privatized or has begun the process of privatization of certain entities and industries, and some investors have suffered losses due to the inability of the newly privatized entities to adjust to a competitive environment and changing regulatory standards.

Recently, Mexico has experienced an outbreak of violence related to criminal gang activity, drug trafficking and terrorist actions. Violence near border areas, border-related political disputes, and other social upheaval may lead to strained international relations. Incidents involving Mexico’s security may have an adverse effect on the Mexican economy and cause uncertainty in its financial markets. Mexico has also experienced contentious and very closely decided elections. Changes in political parties and other political events may affect the economy and contribute to additional instability.

The U.S. is Canada's and Mexico's largest trading and investment partner. The Canadian and Mexican economies are significantly affected by developments in the U.S. economy. Since the implementation of NAFTA in 1994 among Canada, the U.S. and Mexico, total merchandise trade among the three countries has increased. However, political developments in the U.S., including possible termination of NAFTA and imposition of tariffs by the U.S. on Canadian aluminum and steel, may have implications for the trade arrangements among the U.S., Mexico and Canada, which could negatively affect the value of securities held by a Fund. Policy and legislative changes in one country may have a significant effect on North American markets generally, as well as on the value of certain securities held by a Fund.

Risk of Investing in Russia. Investing in the Russian securities market involves a high degree of risk and special considerations not typically associated with investing in the U.S. securities market, and should be considered highly speculative. Risks include: the absence of developed legal structures governing private and foreign investments and private property; the possibility of the loss of all or a substantial portion of a Fund’s assets invested in Russia as a result of expropriation; certain national policies which may restrict the Fund’s investment opportunities, including, without limitation, restrictions on investing in issuers or industries deemed sensitive to relevant national interests; and potentially greater price volatility in, significantly smaller capitalization of, and relative illiquidity of, the Russian market. There can also be no assurance that a Fund’s investments in the Russian securities market would not be expropriated, nationalized or otherwise confiscated. In the event of the settlement of any such claims or such expropriation, nationalization or other confiscation, a Fund could lose its entire investment. In addition, it may be difficult and more costly to obtain and enforce a judgment in the Russian court system.

Russia may also be subject to a greater degree of economic, political and social instability than is the case in other developed countries. Such instability may result from, among other things, the following: (i) an authoritarian government or military involvement in political and economic decision-making, including changes in government through extra-constitutional means; (ii) popular unrest associated with demands for improved political, economic and social conditions; (iii) internal insurgencies; (iv) hostile relations with neighboring countries; and (v) ethnic, religious and racial disaffection.

The Russian economy is heavily dependent upon the export of a range of commodities including most industrial metals, forestry products and oil and gas. Accordingly, it is strongly affected by international commodity prices and is particularly

vulnerable to any weakening in global demand for these products. Any acts of terrorism or armed conflicts in Russia or internationally could have an adverse effect on the financial and commodities markets and the global economy. As Russia produces and exports large amounts of crude oil and gas, any acts of terrorism or armed conflict causing disruptions of Russian oil and gas exports could negatively affect the Russian economy and, thus, adversely affect the financial condition, results of operations or prospects of related companies. Current and future economic sanctions may also adversely affect the Russian oil, banking, mining, metals, rail, pipeline and gas sectors, among other sectors.

The Russian government may exercise substantial influence over many aspects of the private sector and may own or control many companies. Future government actions could have a significant effect on the economic conditions in Russia, which could have a negative impact on private sector companies. There is also the possibility of diplomatic developments that could adversely affect investments in Russia. In recent years, the Russian government has begun to take bolder steps to re-assert its regional geopolitical influence (including military steps). Such steps may increase tensions between Russia and its neighbors and Western countries and may negatively affect economic growth.

Russia Sanctions. The U.S. and the EMU of the EU, along with the regulatory bodies of a number of countries including Japan, Australia, Norway, Switzerland and Canada (collectively, “Sanctioning Bodies”), have imposed economic sanctions, which can consist of prohibiting certain securities trades, prohibiting certain private transactions in the energy sector, asset freezes and prohibition of all business, against certain Russian individuals and Russian corporate entities. The Sanctioning Bodies could also institute broader sanctions on Russia. These sanctions, or even the threat of further sanctions, may result in the decline of the value and liquidity of Russian securities, a weakening of the ruble or other adverse consequences to the Russian economy. These sanctions could also result in the immediate freeze of Russian securities and/or funds invested in prohibited assets, impairing the ability of a Fund to buy, sell, receive or deliver those securities and/or assets. Additional sanctions against Russia have been, and may in the future be, imposed by the U.S. or other countries.

The sanctions against certain Russian issuers include prohibitions on transacting in or dealing in issuances of debt or equity of such issuers. Compliance with each of these sanctions may impair the ability of a Fund to buy, sell, hold, receive or deliver the affected securities or other securities of such issuers. If it becomes impracticable or unlawful for a Fund to hold securities subject to, or otherwise affected by, sanctions (collectively, “affected securities”), or if deemed appropriate by BFA, a Fund may prohibit in-kind deposits of the affected securities in connection with creation transactions and instead require a cash deposit, which may also increase a Fund's transaction costs. A Fund may also be legally required to freeze assets in a blocked account.

Also, if an affected security is included in a Fund's Underlying Index, a Fund may, where practicable, seek to eliminate its holdings of the affected security by employing or augmenting its representative sampling strategy to seek to track the investment results of its Underlying Index. The use of (or increased use of) a representative sampling strategy may increase a Fund’s tracking error risk. If the affected securities constitute a significant percentage of the Underlying Index, a Fund may not be able to effectively implement a representative sampling strategy, which may result in significant tracking error between a Fund’s performance and the performance of its Underlying Index.

Current or future sanctions may result in Russia taking counter measures or retaliatory actions, which may further impair the value and liquidity of Russian securities. These retaliatory measures may include the immediate freeze of Russian assets held by a Fund. In the event of such a freeze of any Fund assets, including depositary receipts, a Fund may need to liquidate non-restricted assets in order to satisfy any Fund redemption orders. The liquidation of Fund assets during this time may also result in a Fund receiving substantially lower prices for its securities.

These sanctions may also lead to changes in a Fund’s Underlying Index. A Fund’s index provider may remove securities from its Underlying Index or implement caps on the securities of certain issuers that have been subject to recent economic sanctions. In such an event, it is expected that a Fund will rebalance its portfolio to bring it in line with its Underlying Index as a result of any such changes, which may result in transaction costs and increased tracking error. These sanctions, the volatility that may result in the trading markets for Russian securities and the possibility that Russia may impose investment or currency controls on investors may cause a Fund to invest in, or increase a Fund’s investments in, depositary receipts that represent the securities of its Underlying Index. These investments may result in increased transaction costs and increased tracking error.

or even the threat of an outbreak of hostilities, could have a severe adverse effect on the South Korean economy. In addition, South Korea's economic growth potential has recently been on a decline, because of a rapidly aging population and structural problems, among other factors. The South Korean economy is heavily reliant on trading exports and disruptions or decreases in trade activity could lead to further declines.

Risk of Investing in the Consumer Cyclical Industry. A Fund may invest in consumer cyclical companies, which rely heavily on business cycles and economic conditions. Consumer cyclical companies include automotive manufacturers, retail companies, and housing-related companies. The consumer cyclical industry can be significantly affected by several factors, including, without limitation, the performance of domestic and international economies, exchange rates, changing consumer tastes and trends, marketing campaigns, cyclical revenue generation, consumer confidence, commodity price volatility, labor relations, interest rates, import and export controls, intense competition, technological developments and government regulation.

Risk of Investing in the Consumer Defensive Industry. A Fund is subject to risks faced by companies in the consumer defensive industry, including: governmental regulation affecting the permissibility of using various food additives and production methods, which could affect profitability; new laws or litigation that may adversely affect tobacco companies; fads, marketing campaigns and other factors affecting supply and demand that may strongly affect securities prices and profitability of food, soft drink and fashion related products; and international events that may affect food and beverage companies that derive a substantial portion of their net income from foreign countries.

gaming casinos, sporting goods and sports arenas, camping and recreational equipment, toys and games, apparel, travel-related services, automobiles, hotels and motels, and fast food and other restaurants) are subject to the risk that their products or services may become obsolete quickly. The success of these companies can depend heavily on disposable household income and consumer spending. During periods of an expanding economy, the consumer discretionary sector may outperform the consumer staples sector, but may underperform when economic conditions worsen. Moreover, the consumer discretionary sector can be significantly affected by several factors, including, without limitation, the performance of domestic and international economies, exchange rates, changing consumer preferences, demographics, marketing campaigns, cyclical revenue generation, consumer confidence, commodity price volatility, labor relations, interest rates, import and export controls, intense competition, technological developments and government regulation.

security may raise significant risks, in addition to the other risks of investing in emerging markets. Additionally, the Middle East, where many companies in the energy sector may operate, has historically and recently experienced widespread social unrest.

Most financial companies are subject to extensive governmental regulation, which limits their activities and may affect their ability to earn a profit from a given line of business. Government regulation may change frequently and may have significant adverse consequences for companies in the financials sector, including effects not intended by the regulation. Direct governmental intervention in the operations of financial companies and financial markets may materially and adversely affect the companies in which a Fund invests, including legislation in many countries that may increase government regulation, repatriation and other intervention. The impact of governmental intervention and legislative changes on any individual financial company or on the financials sector as a whole cannot be predicted. The valuation of financial companies has been and continues to be subject to unprecedented volatility and may be influenced by unpredictable factors, including interest rate risk and sovereign debt default. Certain financial businesses are subject to intense competitive pressures, including market share and price competition. Financial companies in foreign countries are subject to market specific and general regulatory and interest rate concerns. In particular, government regulation in certain foreign countries may include taxes and controls on interest rates, credit availability, minimum capital requirements, bans on short sales, limits on prices and restrictions on currency transfers. In addition, companies in the financials sector may be the targets of hacking and potential theft of proprietary or customer information or disruptions in service, which could have a material adverse effect on their businesses.

Risk of Investing in the Industrials Sector. The value of securities issued by companies in the industrials sector may be adversely affected by supply of and demand for both their specific products or services and for industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events and economic conditions may affect the performance of companies in the industrials sector. The industrials sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors. Aerospace and defense companies, a component of the industrials sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on government demand for their products and services. Thus, the financial condition of, and investor interest in, aerospace and defense companies are heavily influenced by governmental defense spending policies, which are typically under pressure from efforts to control government budgets. Transportation stocks, a component of the industrials sector, are cyclical and can be significantly affected by economic changes, fuel prices, labor relations and insurance costs. Transportation companies in certain countries may also be subject to significant government regulation and oversight, which may adversely affect their businesses. For example, commodity price declines and unit volume reductions resulting from an over-supply of materials used in the industrials sector can adversely affect the sector. Furthermore, companies in the industrials sector may be subject to liability for environmental damage, product liability claims, depletion of resources, and mandated expenditures for safety and pollution control.

new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Finally, while all companies may be susceptible to network security breaches, certain companies in the information technology sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses. These risks are heightened for information technology companies in foreign markets.

Interest Rate Risk. Rising interest rates could result in higher costs of capital for infrastructure companies, which could negatively impact their ability to meet payment obligations.

Oil and Gas Risk. The profitability of oil and gas companies is related to worldwide energy prices, exploration, and production spending.

subject to the quality of credit extended and defaults by borrowers and tenants. If the properties do not generate sufficient income to meet operating expenses, including, where applicable, debt service, ground lease payments, tenant improvements, third-party leasing commissions and other capital expenditures, the income and ability of a Real Estate Company to make payments of any interest and principal on its debt securities will be adversely affected.

Property Risk. Real Estate Companies may be subject to risks relating to functional obsolescence or reduced desirability of properties; extended vacancies due to economic conditions and tenant bankruptcies; catastrophic events such as earthquakes, hurricanes and terrorist acts; and casualty or condemnation losses. Real estate income and values also may be greatly affected by demographic trends, such as population shifts or changing tastes and values, or increasing vacancies or declining rents resulting from legal, cultural, technological, global or local economic developments.

Liquidity Risk. Investing in Real Estate Companies may involve risks similar to those associated with investing in small-capitalization companies. Real Estate Company securities, like the securities of small-capitalization companies, may be more volatile than, and perform differently from, shares of large-capitalization companies. There may be less trading in Real Estate Company shares, which means that buy and sell transactions in those shares could have a magnified impact on share price, resulting in abrupt or erratic price fluctuations. In addition, real estate is relatively illiquid, and, therefore, a Real Estate Company may have a limited ability to vary or liquidate properties in response to changes in economic or other conditions.

U.S. Tax Risk. Certain U.S. Real Estate Companies are subject to special U.S. federal tax requirements. A REIT that fails to comply with such tax requirements may be subject to U.S. federal income taxation, which may affect the value of the REIT and the characterization of the REIT’s distributions. The U.S. federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. A REIT that successfully maintains its qualification may still become subject to U.S. federal, state and local taxes, including excise, penalty, franchise, payroll, mortgage recording, and transfer taxes, both directly and indirectly through its subsidiaries.

Risk of Investing in the Timber and Forestry Industry. The market value of timber and forestry companies may be negatively affected by events occurring in nature and by international and local politics. Natural disasters such as wild fires, volcanic eruptions, flooding, and severe weather conditions may affect the output of timber and timber-related products, and demand for timber and timber-related products in the U.S. and internationally may decrease due to new or changed tariffs, quotas or trade agreements. Rising interest rates or unfavorable economic conditions could also negatively affect the prices of or demand for timber and timber-related products.

Companies in the transportation infrastructure industry may be adversely affected by adverse weather, acts of terrorism or catastrophic events, such as air accidents, train crashes or tunnel fires. Companies in the transportation infrastructure industry may also be subject to the risk of widespread disruption of technology systems and increasing equipment and operational costs.

There are substantial differences among the regulatory practices and policies of various jurisdictions, and any regulatory agency may make major shifts in policy from time to time. There is no assurance that regulatory authorities will, in the future, grant rate increases. Additionally, existing and possible future regulatory legislation may make it even more difficult for utilities to obtain adequate relief. Certain of the issuers of securities held in a Fund's portfolio may own or operate nuclear generating facilities. Governmental authorities may from time to time review existing policies and impose additional requirements governing the licensing, construction and operation of nuclear power plants. Prolonged changes in climate conditions can also have a significant impact on both the revenues of an electric and gas utility as well as the expenses of a utility, particularly a hydro-based electric utility.

Proxy Voting Policy

Portfolio Holdings Information

The Board has adopted a policy regarding the disclosure of the Funds' portfolio holdings information that requires that such information be disclosed in a manner that: (i) is consistent with applicable legal requirements and in the best interests of each Fund’s shareholders; (ii) does not put the interests of BFA, the Distributor or any affiliated person of BFA or the Distributor, above those of Fund shareholders; (iii) does not advantage any current or prospective Fund shareholders over any other current or prospective Fund shareholders, except to the extent that certain Entities (as described below) may receive portfolio holdings information not available to other current or prospective Fund shareholders in connection with the dissemination of information necessary for transactions in Creation Units, as discussed below, and certain information may be provided to personnel of BFA and its affiliates who manage funds that invest a significant percentage of their assets in shares of the Fund for the purpose of facilitating risk management and hedging activities; and (iv) does not provide selective access to portfolio holdings information except pursuant to the procedures outlined below and to the extent appropriate confidentiality arrangements limiting the use of such information are in effect. The “Entities” referred to in sub-section (iii) above are generally limited to National Securities Clearing Corporation (“NSCC”) members, subscribers to various fee-based subscription services, large institutional investors (known as “Authorized Participants”) that have been authorized by the Distributor to purchase and redeem large blocks of shares pursuant to legal requirements and market makers and other institutional market participants and entities that provide information or transactional services.

The Board reviews the policy and procedures for disclosure of portfolio holdings information at least annually.

Construction and Maintenance of the Underlying Indexes

Descriptions of the Underlying Indexes are provided below.

Nifty 50 Index^TM

Number of Components: 50

Index Description. The Nifty 50 Index^TM is designed to measure the equity performance of the top 50 companies by free float market capitalization whose equity securities trade in the Indian securities markets that are available to international investors on the National Stock Exchange of India Ltd. (“NSE”). The securities in the Underlying Index are free float market capitalization-weighted so that securities with higher total free float market capitalization have a larger representation in the Underlying Index.

Index Committee. India Index Services & Products Ltd. (“IISL”), a group company of NSE, are primarily rules-based and monitored by a governing committee.

IISL has constituted an Index Policy Committee that is involved in the policy and guidelines for managing indices. The Index Maintenance Subcommittee takes all decisions on additions and deletions of companies in indices.

Index Maintenance. Changes in the Nifty 50 Index^TM level reflect changes in the free-float market capitalization of the constituents of the Nifty 50 Index^TM which are caused by stock price movements in the market. When a stock is replaced by another stock within the Nifty 50 Index^TM, the index divisor is adjusted so the change in Nifty 50 Index^TM market value that results from the addition and deletion does not change the index level.

Index Availability. The Nifty 50 Index^TM is calculated continuously and is available from major data vendors. For purposes of reporting performance of the Fund, the index provider will also make available to the Fund Nifty 50 Index^TM values in U.S. dollars on an end of day basis by applying a foreign exchange rate calculation to the Nifty 50 Index^TM as determined by the index provider.

Component Selection Criteria. In addition to domicile within India and a listing on the NSE, component security selection decisions include the following criteria:

Eligibile Securities:

Constituents of Nifty 100 Index that are available for trading in NSE’s Futures & Options segment, and the company’s trading frequency is 100% in the last six months, are eligible for inclusion in the Nifty 50 Index^TM.

Liquidity:

For inclusion in the index, the security should have traded at an average impact cost of 0.50% or less during the last six months for 90% of the observations for a portfolio of 100 million Indian Rupees. Impact cost is the cost of executing a transaction in a security in proportion to its index weight, measured by market capitalization at any point in time. This is the percentage mark-up suffered while buying/selling the desired quantity of a security compared to its ideal price – (best buy + best sell)/2.

Float-Adjusted Market Capitalization:

Companies will be eligible for inclusion in the Nifty 50 Index^TMprovided the average free-float market capitalization is at least 1.5 times the average free-float market capitalization of the smallest constituent in the index.

Listing History:

A company which comes out with an Initial Public Offering (“IPO”) is eligible for inclusion in the index if it fulfills the normal eligibility criteria for the index – impact cost and float-adjusted market capitalization – for a three-month period instead of a six-month period.

The Morningstar Indexes

Component Selection Criteria. The Morningstar^® Global ex-US Dividend Growth Index^SM is a subset of the Morningstar^® Global Markets ex-US Index^SM, which is a diversified broad market index that represents approximately 97% of the market capitalization in international developed and emerging markets. To be eligible for inclusion in the Morningstar^® Global Markets ex-US Index^SM, companies must pay a qualified dividend, must have at least five years of uninterrupted annual dividend growth and their earnings payout ratio must be less than 75%. Companies that are in the top decile based on dividend yield are excluded from the Underlying Index prior to the dividend growth and payout ratio screens.

Issue Changes. Securities are added or deleted from the index based on rules outlined for security selection, exclusion, rebalancing, and adjustments for corporate actions as set forth in the Morningstar Index Rulebook. Morningstar makes no subjective determinations related to index composition.

Index Maintenance. The Morningstar^® Global Markets ex-US Index^SM is reconstituted twice annually, on the Monday following the third Friday of June and the Monday following the third Friday of December. The Morningstar^® Global ex-US Dividend Growth Index^SM is reconstituted once annually on the Monday following the third Friday December. If the Monday is a holiday, reconstitution occurs on the Tuesday immediately following. Reconstitution is carried out after the day’s closing index values have been determined.

Index Availability. Morningstar Indexes are calculated continuously and are available from major data vendors.

Morningstar^® Global ex-US Dividend Growth Index^SM

Number of Components: approximately 660

Index Description. The Morningstar^® Global ex-US Dividend Growth Index^SM, the Underlying Index, is a dividend dollars weighted index that seeks to measure the performance of international equities selected based on a consistent history of growing dividends. The Underlying Index is a subset of the Morningstar^® Global Markets ex-US Index^SM, which is a diversified broad market index that represents approximately 97% of the market capitalization in international developed and emerging markets. As of March 31, 2018, the Underlying Index was comprised of securities of companies in the following markets: Australia, Austria, Belgium, Brazil, Canada, China, Colombia, Denmark, Finland, France, Germany, Hong Kong, Hungary, India, Indonesia, Ireland, Israel, Italy, Japan, Malaysia, Mexico, the Netherlands, New Zealand, Norway, Pakistan, Peru, the Philippines, Portugal, the Russian Federation, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand, Turkey, United Arab Emirates and the U.K. Eligible companies must pay a qualified dividend, must have at least five years of uninterrupted annual dividend growth and their earnings payout ratio must be less than 75%. Companies that are in the top decile based on dividend yield are excluded from the Underlying Index prior to the dividend growth, payout ratio, and passive foreign investment company (“PFIC”) screens.

Index Methodology. The Underlying Index methodology is as follows:

(1) a security must be a member of the Morningstar^® Global Markets ex-US Index^SM

(2) security must pay a qualified dividend (e.g., REITs are excluded);

(3) top decile yield payers are excluded;

(4.1) apply dividend growth screen: must be currently paying dividends and have at least five years of uninterrupted annual dividend growth; dividend growth condition is considered met if the trailing twelve months aggregated dividend increased from the previous to the current reconstitution date;

(4.2) spinoff exception to growth rule: for a current constituent of the index, the requirement to raise dividend year-over-year to remain in the index after reconstitution will be waived if the constituent completed a spin-off in the preceding twelve months; any publicly trading spun-off entity of a current constituent will be immediately included in the index, but it will have to start increasing its dividend starting with the year following the next reconstitution to remain in the index. The current constituent will not require dividend growth in the spin-off year, where “year” means the twelve-month period between annual index reconstitutions;

(4.3) share repurchase exception to growth rule: for a current constituent of the index, the requirement to raise dividend year-over-year to remain in the index after reconstitution will be waived if the constituent kept the dividend constant and executed share repurchases in the preceding twelve months resulting in net decrease in its shares outstanding; this exception does not apply to constituents that decreased their dividend;

(5) apply growth sustainability screen: payout ratio must be less than 75%, and must have positive consensus earnings forecast. Payout ratio is forward looking and is calculated by the trailing twelve month divided by the forward 12 month consensus earnings forecast;

(6) apply PFIC screen: exclude PFICs based on best efforts to identify them;

(7) weight by dividend dollars (float adjusted common shares multiplied by the current trailing twelve month dividend rate per share);

(8) apply 3% weight cap on individual names to maintain sufficient diversification. The weight capping algorithm will preserve, starting with the smallest security, the relative weights between as many constituents as possible while enforcing the weight cap;

(9) apply 20% single country cap to maintain sufficient geographical diversification. The weight capping algorithm will preserve, starting with the smallest country, the relative weights between as many countries as possible while enforcing the weight cap; and

(10) the index is reconstituted annually and rebalanced quarterly; at rebalance, index constituent list is not altered, but the weights of the constituents are re-adjusted back to the dividend dollar weighting and the weight constraints are re-applied.

The S&P Indexes

Component Selection Criteria for Domestic Indexes. S&P Dow Jones Indices LLC’s (“SPDJI”) various Index Committees are responsible for the overall management of S&P Dow Jones Indices LLC's indices (“S&P DJI Indices”). Issuers (i.e., the “components”) selected for the Standard & Poor’s Financial Services LLC (“S&P”) U.S. indexes represent a broad range of industry segments within the U.S. economy. The starting universe of publicly traded U.S. issuers classified by the Global Industry Classification Standard (GICS^®) is screened to eliminate ADRs, mutual funds, limited partnerships, royalty trusts, certain holding issuers, OTC bulletin board issues, pink sheet-listed issues, closed-end funds, ETFs and tracking stocks. REITs, except for mortgage REITs, are eligible for inclusion in the Indexes. The stock of each constituent must trade on either the New York Stock Exchange (“NYSE”), the NYSE Amex Equities or on NASDAQ. Additionally, only one share class per constituent will be included in an Index. The share class is selected by SPDJI and is generally defined as the largest, most liquid share class. Issuers with multiple share classes will have the classes combined for purposes of calculation of market capitalization. The following criteria are then analyzed to determine an issuer’s eligibility for inclusion in the S&P Indexes: (i) ownership of an issuer’s outstanding common stock, in order to screen out closely held issuers; (ii) trading volume of an issuer’s shares, in order to ensure ample liquidity and efficient share pricing; and (iii) the financial and operating condition of an issuer.

securities are then screened for industry sector classification; thus, the eligible securities are ranked according to GICS. Then, the Index components, now determined, are weighted on the basis of SPDJI’s float-adjusted, market capitalization methodology. Generally, SPDJI observes a prospective constituent’s liquidity over a period of at least six months before consideration for inclusion. However, there may be extraordinary situations when issuers should be added immediately (e.g., certain privatizations). When a particular issuer dominates its home market, it may be excluded from an Index if analysis of the sectors reveals that its securities are not as liquid as those of similar issuers in other countries. Once a year, the float adjustments will be reviewed and potentially changed based on such review. The values of an Index’s constituents are adjusted to reflect changes in capitalization resulting from mergers, acquisitions, stock rights, substitutions and other capital events. The market capitalization of index constituent issuers is adjusted for all strategic holdings, including private, corporate, and government holdings.

With respect to the non-U.S. components of the S&P Global Indexes, the eligible universe of index components that are considered for inclusion are from the following S&P DJI Indices: (i) the S&P/TSX 60 (Toronto Stock Exchange), which represents the liquid, large-cap stocks of the publicly listed issuers in the Canadian equities market; (ii) the S&P/TOPIX 150 (Tokyo Stock Exchange) which represents the liquid, large-cap stocks of the publicly-listed issuers in the Japanese equities market; (iii) S&P/ASX All-Australian 50 Index (Australian Stock Exchange), which represents the liquid, large-cap stocks in the Australian equities market; (iv) the S&P Asia 50, which represents the liquid, large-cap stocks of four major equities markets in Asia (Hong Kong, South Korea, Taiwan and Singapore); (v) the S&P Latin America 40, which represents the liquid, large-cap stocks from major sectors of the Mexico, Brazil, Peru, Colombia and Chilé equity markets; and (vi) the S&P Europe 350, which represents the liquid, large-cap stocks of the publicly listed issuers in the region, covering approximately 70% of the region’s market capitalization.

Index Availability. The S&P Indexes are calculated continuously and are available from major data vendors.

Exchange Rates. SPDJI uses the World Markets/Reuters Closing Spot Rates taken at 4:00 p.m. London time for the following funds: iShares Global Healthcare ETF, iShares Global Materials ETF, iShares Global Tech ETF and iShares Latin America 40 ETF. Prior to January 31, 2013, SPDJI used the currency exchange (FX) rate corresponding to 5:15 p.m. Eastern time (with the exception of iShares Asia 50 ETF). In case World Markets/Reuters does not provide rates for specific markets on given days (for example, Christmas Day and New Year’s Day), the previous business day’s rates are normally used. SPDJI independently monitors the exchange rates on all its indexes. SPDJI may under exceptional circumstances elect to use alternative sources of exchange rates if the World Markets/Reuters rates are not available, or if SPDJI determines that the World Markets/Reuters rates are not reflective of market circumstances for a given currency on a particular day.

Notations Regarding the iShares International Dividend Growth ETF’s Fundamental Investment Restrictions

The following notations are not considered to be part of the iShares International Dividend Growth ETF's fundamental investment restrictions and are subject to change without shareholder approval.

With respect to the fundamental policy relating to concentration set forth in (1) above, the Investment Company Act does not define what constitutes “concentration” in an industry. The SEC staff has taken the position that investment of 25% or more of a fund’s total assets in one or more issuers conducting their principal activities in the same industry or group of industries constitutes concentration. It is possible that interpretations of concentration could change in the future. The policy in (1) above will be interpreted to refer to concentration as that term may be interpreted from time to time. The policy also will be interpreted to permit investment without limit in the following: securities of the U.S. government and its agencies or instrumentalities; securities of state, territory, possession or municipal governments and their authorities, agencies, instrumentalities or political subdivisions; and repurchase agreements collateralized by any such obligations. Accordingly, issuers of the foregoing securities will not be considered to be members of any industry. There also will be no limit on investment in issuers domiciled in a single jurisdiction or country. Finance companies will be considered to be in the industries of their parents if their activities are primarily related to financing the activities of the parents. Each foreign government will be considered to be a member of a separate industry. With respect to the iShares International Dividend Growth ETF's industry classifications, the Fund currently utilizes any one or more of the industry sub-classifications used by one or more widely recognized market indexes or rating group indexes, and/or as defined by Fund management. The policy also will be interpreted to give broad authority to the iShares International Dividend Growth ETF as to how to classify issuers within or among industries.

With respect to the fundamental policy relating to borrowing money set forth in (2) above, the Investment Company Act permits the iShares International Dividend Growth ETF to borrow money in amounts of up to one-third of the Fund’s total assets from banks for any purpose, and to borrow up to 5% of the Fund’s total assets from banks or other lenders for temporary purposes. (The iShares International Dividend Growth ETF’s total assets include the amounts being borrowed.) To limit the risks attendant to borrowing, the Investment Company Act requires the iShares International Dividend Growth ETF to maintain at all times an “asset coverage” of at least 300% of the amount of its borrowings. Asset coverage means the ratio that the value of the iShares International Dividend Growth ETF's total assets (including amounts borrowed), minus liabilities other than borrowings, bears to the aggregate amount of all borrowings. Borrowing money to increase portfolio holdings is known as “leveraging.” Certain trading practices and investments, such as reverse repurchase agreements, may be considered to be borrowings or involve leverage and thus are subject to the Investment Company Act restrictions. In accordance with SEC staff guidance and interpretations, when the iShares International Dividend Growth ETF engages in such transactions, the Fund instead of maintaining asset coverage of at least 300%, may segregate or earmark liquid assets, or enter into an offsetting position, in an amount at least equal to the Fund’s exposure, on a mark-to-market basis, to the transaction (as calculated pursuant to requirements of the SEC). The policy in (2) above will be interpreted to permit the iShares International Dividend Growth ETF to engage in trading practices and investments that may be considered to be borrowing or to involve leverage to the extent permitted by the Investment Company Act and to permit the Fund to segregate or earmark liquid assets or enter into offsetting positions in accordance with the Investment Company Act. Short-term credits necessary for the settlement of securities transactions and arrangements with respect to securities lending will not be considered to be borrowings under the policy. Practices and investments that may involve leverage but are not considered to be borrowings are not subject to the policy.

With respect to the fundamental policy relating to underwriting set forth in (5) above, the Investment Company Act does not prohibit the iShares International Dividend Growth ETF from engaging in the underwriting business or from underwriting the securities of other issuers; in fact, in the case of diversified funds, the Investment Company Act permits the Fund to have underwriting commitments of up to 25% of its assets under certain circumstances. Those circumstances currently are that the amount of the iShares International Dividend Growth ETF's underwriting commitments, when added to the value of the Fund’s investments in issuers where the Fund owns more than 10% of the outstanding voting securities of those issuers, cannot exceed the 25% cap. A fund engaging in transactions involving the acquisition or disposition of portfolio securities may be considered to be an underwriter under the 1933 Act. Although it is not believed that the application of the 1933 Act provisions described above would cause the iShares International Dividend Growth ETF to be engaged in the business of underwriting, the policy in (5) above will be interpreted not to prevent the Fund from engaging in transactions involving the acquisition or disposition of portfolio securities, regardless of whether the Fund may be considered to be an underwriter under the 1933 Act or is otherwise engaged in the underwriting business to the extent permitted by applicable law.

With respect to the fundamental policy relating to lending set forth in (7) above, the Investment Company Act does not prohibit the iShares International Dividend Growth ETF from making loans (including lending its securities); however, SEC staff interpretations currently prohibit funds from lending more than one-third of their total assets (including lending its securities), except through the purchase of debt obligations or the use of repurchase agreements. In addition, collateral arrangements with respect to options, forward currency and futures transactions and other derivative instruments (as applicable), as well as delays in the settlement of securities transactions, will not be considered loans.

Non-Fundamental Investment Policies

iShares International Dividend Growth ETF

The Fund has adopted a non-fundamental policy not to make short sales of securities or maintain a short position, except to the extent permitted by the Fund’s Prospectus and SAI, as amended from time to time, and applicable law.

Unless otherwise indicated, all limitations under the Fund’s fundamental or non-fundamental investment restrictions apply only at the time that a transaction is undertaken. Any change in the percentage of the Fund’s assets invested in certain securities or other instruments resulting from market fluctuations or other changes in the Fund’s total assets will not require the Fund to dispose of an investment until BFA determines that it is practicable to sell or close out the investment without undue market or tax consequences.

All Funds Other Than the iShares International Dividend Growth ETF

BFA monitors the liquidity of restricted securities in each Fund's (other than the iShares International Dividend Growth ETF's) portfolio. In reaching liquidity decisions, BFA considers the following factors:

•	The frequency of trades and quotes for the security;
•	The number of dealers wishing to purchase or sell the security and the number of other potential purchasers;
•	Dealer undertakings to make a market in the security; and
•	The nature of the security and the nature of the marketplace in which it trades (e.g., the time needed to dispose of the security, the method of soliciting offers and the mechanics of transfer).

All Funds

purposes, in securities of the Underlying Index or in depositary receipts representing component securities in the Underlying Index. Each Fund also has adopted a policy to provide its shareholders with at least 60 days’ prior written notice of any change in such policy. If, subsequent to an investment, the 80% requirement is no longer met, a Fund’s future investments will be made in a manner that will bring the Fund into compliance with this policy.

Each Fund (except the iShares India 50 ETF) has adopted a non-fundamental limitation such that, under normal market conditions, any borrowings by the Fund will not exceed 10% of the Fund's net assets.

Continuous Offering

Broker-dealer firms should also note that dealers who are not “underwriters” but are effecting transactions in shares, whether or not participating in the distribution of shares, generally are required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(a)(3) of the 1933 Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. Firms that incur a prospectus delivery obligation with respect to shares of the Funds are reminded that, pursuant to Rule 153 under the 1933 Act, a prospectus delivery obligation under Section 5(b)(2) of the 1933 Act owed to an exchange member in connection with a sale on the Listing Exchange generally is satisfied by the fact that the prospectus is available at the Listing Exchange upon request. The prospectus delivery mechanism provided in Rule 153 is available only with respect to transactions on an exchange.

The Board has concluded that, based on each Trustee’s experience, qualifications, attributes or skills on an individual basis and in combination with those of the other Trustees, each Trustee should serve as a Trustee of the Board. Among the attributes common to all Trustees are their ability to review critically, evaluate, question and discuss information provided to them, to interact effectively with the Funds' investment adviser, other service providers, counsel and the independent registered public accounting firm, and to exercise effective business judgment in the performance of their duties as Trustees. A Trustee’s ability to perform his or her duties effectively may have been attained through the Trustee’s educational background or professional training; business, consulting, public service or academic positions; experience from service as a Board member of the Funds and the other funds in the Trust (and any predecessor funds), other investment funds, public companies, or non-profit entities or other organizations; and/or other life experiences. Also, set forth below is a brief discussion of the specific experience, qualifications, attributes or skills of each Trustee that led the Board to conclude that he or she should serve (or continue to serve) as a Trustee.

Board – Leadership Structure and Oversight Responsibilities

The Board has appointed an Independent Trustee to serve in the role of Board Chair. The Board Chair’s role is to preside at all meetings of the Board and to act as a liaison with service providers, officers, attorneys, and other Trustees generally between meetings. The Board Chair may also perform such other functions as may be delegated by the Board from time to time. The Board has established seven standing Committees: a Nominating and Governance Committee, an Audit Committee, a 15(c) Committee, a Securities Lending Committee, a Risk Committee, an Equity Plus Committee and a Fixed Income Plus Committee to assist the Board in the oversight and direction of the business and affairs of the Funds, and from time to time the Board may establish ad hoc committees or informal working groups to review and address the policies and practices of the Funds with respect to certain specified matters. The Chair of each standing Committee is an Independent Trustee. The role of the Chair of each Committee is to preside at all meetings of the Committee and to act as a liaison with service providers, officers, attorneys and other Trustees between meetings. Each standing Committee meets regularly to conduct the oversight functions delegated to the Committee by the Board and reports its finding to the Board. The Board and each standing Committee conduct annual assessments of their oversight function and structure. The Board has determined that the Board’s leadership structure is appropriate because it allows the Board to exercise independent judgment over management and it allocates areas of responsibility among committees of Independent Trustees and the full Board to enhance effective oversight.

The members of the Risk Committee are Jane D. Carlin (Chair), Charles A. Hurty, Drew E. Lawton and John E. Martinez, each of whom is an Independent Trustee. The principal responsibility of the Risk Committee is to consider and organize on behalf of the Board risk related matters of the Funds so the Board may most effectively structure itself to oversee them. The Risk Committee commenced on January 1, 2016. The Risk Committee met five times during the fiscal year ended March 31, 2018.

As the Chair of the Board, Cecilia H. Herbert may serve as an ex-officio member of each Committee.

BlackRock is one of the world's largest asset management firms. PNC is a diversified financial services organization spanning the retail, business and corporate markets. BlackRock, PNC and their respective affiliates (including, for these purposes, their directors, partners, trustees, managing members, officers and employees), including the entities and personnel who may be involved in the investment activities and business operations of a Fund, are engaged worldwide in businesses, including managing equities, fixed-income securities, cash and alternative investments, and banking and other financial services, and have interests other than that of managing a Fund. These are considerations of which investors in a Fund should be aware, and which may cause conflicts of interest that could disadvantage a Fund and its shareholders. These businesses and interests include potential multiple advisory, transactional, financial and other relationships with, or interests in, companies and interests in securities or other instruments that may be purchased or sold by a Fund.

BlackRock and the other Affiliates have proprietary interests in, and may manage or advise with respect to, accounts or funds (including separate accounts and other funds and collective investment vehicles) that have investment objectives similar to those of a Fund and/or that engage in transactions in the same types of securities, currencies and instruments as a Fund. One or more Affiliates are also major participants in the global currency, equities, swap and fixed-income markets, in each case, for the accounts of customers and, in some cases, on a proprietary basis. As such, one or more Affiliates are or may be actively engaged in transactions in the same securities, currencies, and instruments in which a Fund invests. Such activities could affect the prices and availability of the securities, currencies, and instruments in which a Fund invests, which could have an adverse impact on a Fund's performance. Such transactions, particularly in respect of most proprietary accounts or client accounts, will be executed independently of a Fund's transactions and thus at prices or rates that may be more or less favorable than those obtained by a Fund.

accounts managed or advised by BlackRock or the other Affiliates for clients worldwide, and/or the internal policies of BlackRock and the other Affiliates designed to comply with such requirements. As a result, there may be periods, for example, when BlackRock and/or one or more Affiliates will not initiate or recommend certain types of transactions in certain securities or instruments with respect to which BlackRock and/or one or more Affiliates are performing services or when position limits have been reached. For example, the investment activities of one or more Affiliates for their proprietary accounts and accounts under their management may limit the investment opportunities for a Fund in certain emerging and other markets in which limitations are imposed upon the amount of investment, in the aggregate or in individual issuers, by affiliated foreign investors.

At times, these activities may cause departments of BlackRock or the other Affiliates to give advice to clients that may cause these clients to take actions adverse to the interests of a Fund. To the extent affiliated transactions are permitted, a Fund will deal with BlackRock and the other Affiliates (except with respect to BFA or affiliated sub-advisers of a Fund, as applicable) on an arms-length basis.

Subject to applicable law, the Affiliates (and their personnel and other distributors) will be entitled to retain fees and other amounts that they receive in connection with their service to the Funds as broker, dealer, agent, lender, adviser or in other commercial capacities. No accounting to a Fund or its shareholders will be required, and no fees or other compensation payable by a Fund or its shareholders will be reduced by reason of receipt by an Affiliate of any such fees or other amounts.

establish business relationships with its counterparties based on the Fund's own credit standing. Neither BlackRock nor any of the Affiliates will have any obligation to allow their credit to be used in connection with a Fund's establishment of its business relationships, nor is it expected that the Fund's counterparties will rely on the credit of BlackRock or any of the other Affiliates in evaluating the Fund's creditworthiness.

Lending on behalf of a Fund is done by BTC pursuant to SEC exemptive relief, enabling BTC to act as securities lending agent to, and receive a share of securities lending revenues from, the Fund. An Affiliate will also receive compensation for managing the reinvestment of the cash collateral from securities lending. There are potential conflicts of interest in managing a securities lending program, including but not limited to: (i) BTC as securities lending agent may have an incentive to increase or decrease the amount of securities on loan or to lend particular securities in order to generate additional risk-adjusted revenue for BTC and its affiliates; and (ii) BTC as securities lending agent may have an incentive to allocate loans to clients that would provide more revenue to BlackRock. As described further below, BlackRock seeks to mitigate this conflict by providing its securities lending clients with equal lending opportunities over time in order to approximate pro-rata allocation.

Prevailing trading activity frequently may make impossible the receipt of the same price or execution on the entire volume of securities purchased or sold. When this occurs, the various prices may be averaged, and the Funds will be charged or credited with the average price. Thus, the effect of the aggregation may operate on some occasions to the disadvantage of the Funds. In addition, under certain circumstances, the Funds will not be charged the same commission or commission equivalent rates in connection with a bunched or aggregated order.

this manner may be used in servicing other BlackRock client accounts, including in connection with BlackRock client accounts other than those that pay commissions to the broker relating to the research or other service arrangements. Such products and services may disproportionately benefit other BlackRock client accounts relative to the Funds based on the amount of brokerage commissions paid by the Funds and such other BlackRock client accounts. For example, research or other services that are paid for through one client's commissions may not be used in managing that client's account. In addition, other BlackRock client accounts may receive the benefit, including disproportionate benefits, of economies of scale or price discounts in connection with products and services that may be provided to the Funds and to such other BlackRock client accounts. To the extent that BlackRock uses soft dollars, it will not have to pay for those products and services itself.

BlackRock may utilize certain electronic crossing networks (“ECNs”) (including, without limitation, ECNs in which BlackRock or the other Affiliates have an investment or other interest, to the extent permitted by applicable law) in executing client securities transactions for certain types of securities. These ECNs may charge fees for their services, including access fees and transaction fees. The transaction fees, which are similar to commissions or markups/markdowns, will generally be charged to clients and, like commissions and markups/markdowns, would generally be included in the cost of the securities purchased. Access fees may be paid by BlackRock even though incurred in connection with executing transactions on behalf of clients, including the Funds. In certain circumstances, ECNs may offer volume discounts that will reduce the access fees typically paid by BlackRock. BlackRock will only utilize ECNs consistent with its obligation to seek to obtain best execution in client transactions.

BlackRock has adopted policies and procedures designed to prevent conflicts of interest from influencing proxy voting decisions that it makes on behalf of advisory clients, including the Funds, and to help ensure that such decisions are made in accordance with BlackRock's fiduciary obligations to its clients. Nevertheless, notwithstanding such proxy voting policies and procedures, actual proxy voting decisions of BlackRock may have the effect of favoring the interests of other clients or businesses of other divisions or units of BlackRock and/or the other Affiliates, provided that BlackRock believes such voting decisions to be in accordance with its fiduciary obligations. For a more detailed discussion of these policies and procedures, see the Proxy Voting Policy section of this SAI.

other Affiliates has significant debt or equity investments or other interests or in which an Affiliate makes a market. A Fund also may invest in securities of, or engage in transactions with, companies to which an Affiliate provides or may in the future provide research coverage. Such investments or transactions could cause conflicts between the interests of a Fund and the interests of BlackRock, other clients of BlackRock or the other Affiliates. In making investment decisions for a Fund, BlackRock is not permitted to obtain or use material non-public information acquired by any division, department or Affiliate of BlackRock in the course of these activities. In addition, from time to time, the activities of an Affiliate may limit a Fund's flexibility in purchases and sales of securities. When an Affiliate is engaged in an underwriting or other distribution of securities of an entity, BlackRock may be prohibited from purchasing or recommending the purchase of certain securities of that entity for a Fund. As indicated below, BlackRock or the other Affiliates may engage in transactions with companies in which BlackRock-advised funds or other clients of BlackRock or of an Affiliate have an investment.

BlackRock and the other Affiliates may provide valuation assistance to certain clients with respect to certain securities or other investments and the valuation recommendations made for their clients' accounts may differ from the valuations for the same securities or investments assigned by a Fund's pricing vendors, especially if such valuations are based on broker-dealer quotes or other data sources unavailable to the Fund's pricing vendors. While BlackRock will generally communicate its valuation information or determinations to a Fund's pricing vendors and/or fund accountants, there may be instances where the Fund's pricing vendors or fund accountants assign a different valuation to a security or other investment than the valuation for such security or investment determined or recommended by BlackRock.

selling an asset or liability at a later time or if it holds the asset or liability to maturity. While fair value determinations will be based upon all available factors that BlackRock deems relevant at the time of the determination, and may be based on analytical values determined by BlackRock using proprietary or third-party valuation models, fair value represents only a good faith approximation of the value of an asset or liability. The fair value of one or more assets or liabilities may not, in retrospect, be the price at which those assets or liabilities could have been sold during the period in which the particular fair values were used in determining a Fund’s net asset value. As a result, a Fund’s sale or redemption of its shares at net asset value, at a time when a holding or holdings are valued by BlackRock (pursuant to Board-adopted procedures) at fair value, may have the effect of diluting or increasing the economic interest of existing shareholders and may affect the amount of revenue received by BlackRock with respect to services for which it receives an asset-based fee.

BlackRock and the other Affiliates and their directors, officers and employees, may buy and sell securities or other investments for their own accounts and may have conflicts of interest with respect to investments made on behalf of a Fund. As a result of differing trading and investment strategies or constraints, positions may be taken by directors, officers, employees and Affiliates that are the same, different from or made at different times than positions taken for a Fund. To lessen the possibility that a Fund will be adversely affected by this personal trading, each Fund, BFA and BlackRock, Inc. have each adopted a code of ethics in compliance with Section 17(j) of the 1940 Act that restricts securities trading in the personal accounts of investment professionals and others who normally come into possession of information regarding a Fund's portfolio transactions. Each code of ethics is available by contacting BlackRock or by accessing the EDGAR Database on the SEC's Internet site at http://www.sec.gov, and copies may be obtained, after paying a duplicating fee, by e-mail at publicinfo@sec.gov or by writing the SEC's Public Reference Room, Washington, DC 20549-1520. Information about accessing documents on the SEC’s website may be obtained by calling the SEC at (800) SEC-0330.

BlackRock and the other Affiliates will not purchase securities or other property from, or sell securities or other property to, a Fund, except that a Fund may in accordance with rules or guidance adopted under the 1940 Act engage in transactions with accounts that are affiliated with a Fund as a result of common officers, directors, or investment advisers or pursuant to exemptive orders granted to the Funds and/or BlackRock by the SEC. These transactions would be effected in circumstances in which BlackRock determined that it would be appropriate for a Fund to purchase and another client of BlackRock to sell, or a Fund to sell and another client of BlackRock to purchase, the same security or instrument on the same day. From time to time, the activities of a Fund may be restricted because of regulatory requirements applicable to BlackRock or the other Affiliates and/or BlackRock's internal policies designed to comply with, limit the applicability of, or otherwise relate to such requirements. A client not advised by BlackRock would not be subject to some of those considerations. There may be periods when BlackRock may not initiate or recommend certain types of transactions, or may otherwise restrict or limit their advice in certain securities or instruments issued by or related to companies for which an Affiliate is performing investment banking, market making, advisory or other services or has proprietary positions. For example, when an Affiliate is engaged in an underwriting or other distribution of securities of, or advisory services for, a company, the Funds may be prohibited from or limited in purchasing or selling securities of that company. In addition, when BlackRock provides advisory or risk management services for a company, BlackRock may be prohibited from or limited in purchasing or selling securities of that company on behalf of a Fund, particularly where such services result in BlackRock obtaining material non-public information about the company (e.g., in connection with participation in a creditors’ committee). Similar situations could arise if personnel of BlackRock or the other Affiliates serve as directors of companies the securities of which a Fund wishes to purchase or sell. However, if permitted by applicable law, and where consistent with BlackRock’s policies and procedures (including the necessary implementation of appropriate information barriers), the Funds may purchase securities or instruments that are issued by such companies, are the subject of an underwriting, distribution or advisory assignment by an Affiliate, or are the subject of an advisory or risk management assignment by BlackRock, or where personnel of BlackRock or the other Affiliates are directors or officers of the issuer.

client accounts (including the Funds) that may not be exceeded without the grant of a license or other regulatory or corporate consent or, if exceeded, may cause BlackRock, the Funds or other client accounts to suffer disadvantages or business restrictions.

In those circumstances where ownership thresholds or limitations must be observed, BlackRock seeks to allocate limited investment opportunities equitably among clients (including the Funds), taking into consideration benchmark weight and investment strategy. BlackRock has adopted certain controls designed to prevent the occurrence of a breach of any applicable ownership threshold or limits, including, for example, when ownership in certain securities nears an applicable threshold, BlackRock may remove such securities from the list of Deposit Securities to be delivered to the Fund in connection with purchases of Creation Units of such Fund and may limit purchases in such securities to the issuer's weighting in the applicable benchmark used by BlackRock to manage such Fund. If client (including Fund) holdings of an issuer exceed an applicable threshold and BlackRock is unable to obtain relief to enable the continued holding of such investments, it may be necessary to sell down these positions to meet the applicable limitations. In these cases, benchmark overweight positions will be sold prior to benchmark positions being reduced to meet applicable limitations.

BlackRock and the other Affiliates may not serve as Authorized Participants in the creation and redemption of iShares ETFs, but may serve as authorized participants of third-party ETFs.

BlackRock or the other Affiliates own or have an ownership interest in certain trading, portfolio management, operations and/or information systems used by Fund service providers. These systems are, or will be, used by a Fund service provider in connection with the provision of services to accounts managed by BlackRock and funds managed and sponsored by BlackRock, including the Funds, that engage the service provider (typically the custodian). A Fund’s service provider remunerates BlackRock or the other Affiliates for the use of the systems. A Fund service provider’s payments to BlackRock or the other Affiliates for the use of these systems may enhance the profitability of BlackRock and the other Affiliates. BlackRock’s or the other Affiliates’ receipt of fees from a service provider in connection with the use of systems provided by BlackRock or the other Affiliates may create an incentive for BlackRock to recommend that a Fund enter into or renew an arrangement with the service provider.

Present and future activities of BlackRock and the other Affiliates, including BFA, in addition to those described in this section, may give rise to additional conflicts of interest.

in the event of a “flash crash,” such as the one that occurred on May 6, 2010. On September 18, 2017, the court issued a Statement of Decision holding that the Plaintiffs lack standing to assert their claims. On October 11, 2017, the court entered final judgment dismissing all of Plaintiffs’ claims with prejudice. Plaintiffs have appealed the court’s decision.

Investment Advisory, Administrative and Distribution Services

Pursuant to the investment advisory agreement, BFA may, from time to time, in its sole discretion and to the extent permitted by applicable law, appoint one or more sub-advisers, including, without limitation, affiliates of BFA, to perform investment advisory or other services with respect to a Fund. In addition, BFA may delegate certain of its investment advisory functions under the investment advisory agreement to one or more of its affiliates to the extent permitted by applicable law. BFA may terminate any or all sub-advisers or such delegation arrangements in its sole discretion upon appropriate notice at any time to the extent permitted by applicable law.

For its investment advisory services to the iShares Global Healthcare ETF, iShares Global Materials ETF, iShares Global Tech ETF and iShares Global Timber & Forestry ETF, BFA is paid a management fee from each Fund corresponding to the Fund’s allocable portion of an aggregate management fee calculated based on the aggregate average daily net assets of the following iShares funds: iShares Global Clean Energy ETF, iShares Global Consumer Discretionary ETF, iShares Global Consumer Staples ETF, iShares Global Energy ETF, iShares Global Financials ETF, iShares Global Healthcare ETF, iShares Global Industrials ETF, iShares Global Infrastructure ETF, iShares Global Materials ETF, iShares Global Tech ETF, iShares Global Telecom ETF, iShares Global Timber & Forestry ETF, iShares Global Utilities ETF, iShares North American Natural Resources ETF, iShares North American Tech ETF, iShares North American Tech-Multimedia Networking ETF, iShares North American Tech-Software ETF and iShares PHLX Semiconductor ETF. The aggregate management fee for the iShares funds listed above is calculated as follows: 0.48% per annum of the aggregate net assets of those Funds less than or equal to $10.0 billion, plus 0.43% per annum of the aggregate net assets over $10.0 billion, up to and including $20.0 billion, plus 0.38% per annum of the aggregate net assets in excess of $20.0 billion.

For its investment advisory services to the iShares Latin America 40 ETF, BFA is paid a management fee from the Fund calculated based on the aggregate average daily net assets of the following iShares funds: iShares Latin America 40 ETF, iShares MSCI Pacific ex Japan ETF, iShares Russell 2000 ETF, iShares Russell 2000 Growth ETF, iShares Russell 2000 Value ETF, iShares Select Dividend ETF and iShares U.S. Preferred Stock ETF. The management fee for the Fund equals the ratio of the Fund’s net assets over the aggregate net assets of the above iShares funds multiplied by the amount calculated as follows: 0.5000% per annum of the aggregate net assets less than or equal to $46.0 billion, plus 0.4750% per annum of the aggregate net assets over $46.0 billion, up to and including $81.0 billion, plus 0.4513% per annum of the aggregate net assets over $81.0 billion, up to an including $111.0 billion, plus 0.4287% per annum of the aggregate net assets over $111.0 billion, up to and including $141.0 billion, plus 0.4073% per annum of the aggregate net assets in excess of $141.0 billion.

For the iShares Emerging Markets Infrastructure ETF, BFA has contractually agreed to waive its management fees in an amount equal to the “Acquired Fund Fees and Expenses,” if any, attributable to the Fund’s investments in other series of iShares Trust and iShares, Inc., through July 31, 2022. The contractual waiver may be terminated prior to July 31, 2022 only upon written agreement of the Trust and BFA. For the fiscal years ended March 31, 2018 and March 31, 2017, BFA waived $0 and $0 of management fees.

For the iShares India 50 ETF, the Subsidiary has entered into a separate contract with BFA whereby BFA provides investment advisory services to the Subsidiary. BFA does not receive separate compensation from the Subsidiary for providing it with investment advisory services. The Fund pays BFA a management fee based on the Fund's assets, including the assets invested in the Subsidiary. The Subsidiary has also entered into separate arrangements that provide for the provision of other services to the Subsidiary (including administrative, custody, transfer agency and other services), and BFA shall pay the costs and expenses related to the provision of those services.

Each of the portfolios or accounts for which the Portfolio Managers are primarily responsible for the day-to-day management seeks to track the rate of return, risk profile and other characteristics of independent third-party indexes by either replicating the same combination of securities and other financial instruments that constitute those indexes or through a representative sampling of the securities and other financial instruments that constitute those indexes based on objective criteria and data. Pursuant to BFA’s policy, investment opportunities are allocated equitably among the Funds and other portfolios and accounts. For example, under certain circumstances, an investment opportunity may be restricted due to limited supply in the market, legal constraints or other factors, in which event the investment opportunity will be allocated equitably among those portfolios and accounts, including the Funds, seeking such investment opportunity. As a consequence, from time to time each Fund may receive a smaller allocation of an investment opportunity than it would have if the Portfolio Managers and BFA and its affiliates did not manage other portfolios or accounts.

Like the Funds, the other portfolios or accounts for which the Portfolio Managers are primarily responsible for the day-to-day portfolio management generally pay an asset-based fee to BFA or its affiliates, as applicable, for its advisory services. One or more of those other portfolios or accounts, however, may pay BFA or its affiliates a performance-based fee in lieu of, or in addition to, an asset-based fee for its advisory services. A portfolio or account with a performance-based fee would pay BFA or its affiliates a portion of that portfolio’s or account’s gains, or would pay BFA or its affiliates more for its services than would otherwise be the case if BFA or any of its affiliates meets or exceeds specified performance targets. Performance-based fee arrangements could present an incentive for BFA or its affiliates to devote greater resources, and allocate more investment opportunities, to the portfolios or accounts that have those fee arrangements, relative to other portfolios or accounts, in order to earn larger fees. Although BFA and each of its affiliates have an obligation to allocate resources and opportunities equitably among portfolios and accounts and intend to do so, shareholders of the Funds should be aware that,

The discussion below describes the Portfolio Managers' compensation as of March 31, 2018.

Portfolio Manager Compensation Overview

Base compensation. Generally, portfolio managers receive base compensation based on their position with the firm.

Other Compensation Benefits. In addition to base compensation and discretionary incentive compensation, portfolio managers may be eligible to receive or participate in one or more of the following:

Incentive Savings Plans — BlackRock, Inc. has created a variety of incentive savings plans in which BlackRock, Inc. employees are eligible to participate, including a 401(k) plan, the BlackRock Retirement Savings Plan (“RSP”), and the BlackRock Employee Stock Purchase Plan (“ESPP”). The employer contribution components of the RSP include a company match equal to 50% of the first 8% of eligible pay contributed to the plan capped at $5,000 per year, and a company retirement contribution equal to 3-5% of eligible compensation up to the U.S. Internal Revenue Service (the “IRS”) limit ($275,000 for 2018). The RSP offers a range of investment options, including registered investment companies and collective investment funds managed by the firm. BlackRock, Inc. contributions follow the investment direction set by participants for their own contributions or, absent participant investment direction, are invested into an index target date fund that corresponds to, or is closest to, the year in which the participant attains age 65. The ESPP allows for investment in BlackRock, Inc. common stock at a 5% discount on the fair market value of the stock on the purchase date. Annual participation in the ESPP is limited to the purchase of 1,000 shares of common stock or a dollar value of $25,000 based on its fair market value on the Purchase Date. Rachel Aguirre, Diane Hsiung, Jennifer Hsui, Alan Mason, Greg Savage and Amy Whitelaw are each eligible to participate in these plans.

As of March 31, 2018, the Portfolio Managers did not beneficially own shares of the Funds.

Codes of Ethics. The Trust, BFA and the Distributor have adopted codes of ethics pursuant to Rule 17j-1 under the 1940 Act. The codes of ethics permit personnel subject to the codes of ethics to invest in securities, subject to certain limitations, including securities that may be purchased or held by the Funds. The codes of ethics are on public file with, and are available from, the SEC.

Administrator, Custodian and Transfer Agent. State Street serves as administrator, custodian and transfer agent for the Funds under the Master Services Agreement and related Service Schedule (the “Service Module”). State Street’s principal address is 1 Lincoln Street, Boston, MA 02111. Pursuant to the Service Module for Fund Administration and Accounting Services with the Trust, State Street provides necessary administrative, legal, tax and accounting and financial reporting services for the maintenance and operations of the Trust and each Fund. In addition, State Street makes available the office space, equipment, personnel and facilities required to provide such services. Pursuant to the Service Module for Custodial Services with the Trust, State Street maintains, in separate accounts, cash, securities and other assets of the Trust and each Fund, keeps all necessary accounts and records and provides other services. State Street is required, upon the order of the Trust, to deliver securities held by State Street and to make payments for securities purchased by the Trust for each Fund. State Street is authorized to appoint certain foreign custodians or foreign custody managers for Fund investments outside the U.S. Pursuant to the Service Module for Transfer Agency Services with the Trust, State Street acts as a transfer agent for each Fund’s authorized and issued shares of beneficial interest, and as dividend disbursing agent of the Trust. As compensation for these services, State Street receives certain out-of-pocket costs, transaction fees and asset-based fees which are accrued daily and paid monthly by BFA from its management fee.

The following table sets forth the administration, custodian and transfer agency expenses of each Fund paid by BFA to State Street for the fiscal years noted:

records of both orders placed with it or its agents and confirmations of acceptance furnished by it or its agents. The Distributor is a broker-dealer registered under the Securities Exchange Act of 1934, as amended (the “1934 Act”), and a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”).

Pursuant to the Securities Lending Agency Agreement:

(i) The iShares Global Tech ETF (“Domestic Equity Fund”) retains 71.5% of securities lending income (which excludes collateral investment fees) and (ii) this amount can never be less than 65% of the sum of securities lending income plus collateral investment fees.

(i) All Funds except for the iShares Global Tech ETF (“International Equity Funds”) retain 80% of securities lending income (which excludes collateral investment fees) and (ii) this amount can never be less than 70% of the sum of securities lending income plus collateral investment fees.

In addition, commencing the business day following the date that the aggregate securities lending income (which includes, for this purpose, collateral investment fees) earned across the Exchange-Traded Fund Complex (as defined under “Management—Trustees and Officers”) in a calendar year exceeds the aggregate securities lending income earned across the Exchange-Traded Fund Complex in calendar year 2013 (the Hurdle Date), each applicable Fund, pursuant to the securities lending agreement, will receive for the remainder of that calendar year securities lending income as follows:

Domestic Equity Fund

International Equity Funds

the Funds and other iShares funds, or for other activities, such as participation in marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems (“Education Costs”). BFA Entities also make payments to Intermediaries for certain printing, publishing and mailing costs or materials relating to the Funds, other iShares funds or exchange-traded products (“Publishing Costs”). In addition, BFA Entities make payments to Intermediaries that make shares of the Funds, other iShares funds or exchange-traded products available to their clients, develop new products that feature iShares or otherwise promote the Funds, other iShares funds and exchange-traded products. BFA Entities may also reimburse expenses or make payments from their own assets to Intermediaries or other persons in consideration of services or other activities that the BFA Entities believe may benefit the iShares business or facilitate investment in the Funds, other iShares funds or exchange-traded products. Payments of the type described above are sometimes referred to as revenue-sharing payments.

Payments to an Intermediary may be significant to the Intermediary, and amounts that Intermediaries pay to your salesperson or other investment professional may also be significant for your salesperson or other investment professional. Because an Intermediary may make decisions about which investment options it will recommend or make available to its clients or what services to provide for various products based on payments it receives or is eligible to receive, such payments may create conflicts of interest between the Intermediary and its clients and these financial incentives may cause the Intermediary to recommend the Funds, other iShares funds or exchange-traded products over other investments. The same conflicts of interest and financial incentives exist with respect to your salesperson or other investment professional if he or she receives similar payments from his or her Intermediary firm.

In addition to the payments described above, BFA Entities have developed proprietary tools, calculators and related interactive or digital content that is made available through the www.BlackRock.com website at no additional cost to Intermediaries. BlackRock may configure these tools and calculators and localizes the content for Intermediaries as part of its customary digital marketing support and promotion of the Funds, other iShares funds, exchange-traded products and BlackRock mutual funds.

arrangements may include an agreed-upon minimum or maximum payment, or any combination of the foregoing. As of the date of this SAI, BFA anticipates that the payments paid by BFA Entities in connection with the Funds, iShares funds and exchange-traded products in general will be immaterial to BFA Entities in the aggregate for the next year. Please contact your salesperson or other investment professional for more information regarding any such payments or financial incentives his or her Intermediary firm may receive. Any payments made, or financial incentives offered, by the BFA Entities to an Intermediary may create the incentive for the Intermediary to encourage customers to buy shares of the Funds, other iShares funds or other exchange-traded products.

Determination of Net Asset Value

Equity Investments. Equity securities traded on a recognized securities exchange (e.g., NYSE), on separate trading boards of a securities exchange or through a market system that provides contemporaneous transaction pricing information (each, an “Exchange”) are valued using information obtained via independent pricing services, generally at the closing price on the Exchange on which the security is primarily traded, or if an Exchange closing price is not available, the last traded price on that Exchange prior to the time as of which a Fund’s assets or liabilities are valued. However, under certain circumstances, other means of determining current market value may be used. If an equity security is traded on more than one Exchange, the current market value of the security where it is primarily traded generally will be used. In the event that there are no sales involving an equity security held by a Fund on a day on which a Fund values such security, the prior day’s price will be used, unless, in accordance with valuation procedures approved by the Board (the “Valuation Procedures”), BlackRock determines in good faith that such prior day’s price no longer reflects the fair value of the security, in which case such asset would be treated as a Fair Value Asset (as defined below).

as the value of such option. If no such bid or ask price is available on a day on which a Fund values such option, the prior day’s price will be used, unless BlackRock determines in good faith that such prior day’s price no longer reflects the fair value of the option, in which case such option will be treated as a Fair Value Asset (as defined below). OTC derivatives are valued using the last available bid prices or current market quotations provided by dealers or prices (including evaluated prices) supplied by a Fund’s approved independent third-party pricing services, each in accordance with the Valuation Procedures. OTC derivatives may be valued using a mathematical model which may incorporate a number of market data factors. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their settle price as of the close of such exchanges. Swap agreements and other derivatives are generally valued daily based upon quotations from market makers or by a pricing service in accordance with the Valuation Procedures.

Underlying Funds. Shares of underlying ETFs will be valued at their most recent closing price on an Exchange. Shares of underlying money market funds will be valued at their NAV.

All cash, receivables and current payables are carried on a Fund’s books at their face value.

In the event that application of the methods of valuation discussed above result in a price for a security which is deemed not to be representative of the fair market value of such security, the security will be valued by, under the direction of or in accordance with a method approved by the Board as reflecting fair value. All other assets and liabilities (including securities for which market quotations are not readily available) held by a Fund (including restricted securities) are valued at fair value as determined in good faith by the Board or by BlackRock (its delegate) pursuant to the Valuation Procedures. Any assets and liabilities that are denominated in a foreign currency are converted into U.S. dollars using prevailing market rates on the date of valuation as quoted by one or more data service providers.

close of trading for an asset or liability but prior to or at the time of pricing a Fund’s assets or liabilities, and that the event is likely to cause a material change to the closing market price of the assets or liabilities held by a Fund. Non-U.S. securities whose values are affected by volatility that occurs in the markets or in related or highly correlated assets (e.g., ADRs, GDRs or ETFs that invest in components of the Underlying Index) on a trading day after the close of non-U.S. securities markets may be fair valued. On any day the NYSE is open and a foreign market or the primary exchange on which a foreign asset or liability is traded is closed, such asset or liability will be valued using the prior day’s price, provided that BlackRock is not aware of any significant event or other information that would cause such price to no longer reflect the fair value of the asset or liability, in which case such asset or liability would be treated as a Fair Value Asset.

BlackRock, with input from the BlackRock Investment Strategy Group, will submit its recommendations regarding the valuation and/or valuation methodologies for Fair Value Assets to BlackRock’s Valuation Committee. The BlackRock Valuation Committee may accept, modify or reject any recommendations. In addition, a Fund’s accounting agent periodically endeavors to confirm the prices it receives from all third-party pricing services, index providers and broker-dealers, and, with the assistance of BlackRock, to regularly evaluate the values assigned to the securities and other assets and liabilities of a Fund. The pricing of all Fair Value Assets is subsequently reported to and, where appropriate, ratified by the Board.

Fair value represents a good faith approximation of the value of an asset or liability. When determining the fair value of an asset, one or more of a variety of fair valuation methodologies may be used (depending on certain factors, including the asset type). For example, the asset may be priced on the basis of the original cost of the investment or, alternatively, using proprietary or third-party models (including models that rely upon direct portfolio management pricing inputs and which reflect the significance attributed to the various factors and assumptions being considered). Prices of actual, executed or historical transactions in the relevant asset and/or liability (or related or comparable assets and/or liabilities) or, where appropriate, an appraisal by a third-party experienced in the valuation of similar assets and/or liabilities, may also be used as a basis for establishing the fair value of an asset or liability. The fair value of one or more assets or liabilities may not, in retrospect, be the price at which those assets or liabilities could have been sold during the period in which the particular fair values were used in determining a Fund’s NAV. As a result, a Fund’s sale or redemption of its shares at NAV, at a time when a holding or holdings are valued at fair value, may have the effect of diluting or increasing the economic interest of existing shareholders.

Brokerage Transactions

pay the lowest spread or commission available, and payment of the lowest commission or spread is not necessarily consistent with obtaining the best price and execution in particular transactions. Subject to applicable legal requirements, BFA may select a broker based partly upon brokerage or research services provided to BFA and its clients, including a Fund. In return for such services, BFA may cause a Fund to pay a higher commission than other brokers would charge if BFA determines in good faith that the commission is reasonable in relation to the services provided.

OTC issues, including most fixed-income securities such as corporate debt and U.S. Government securities, are normally traded on a “net” basis without a stated commission, through dealers acting for their own account and not as brokers. The Funds will primarily engage in transactions with these dealers or deal directly with the issuer unless a better price or execution could be obtained by using a broker. Prices paid to a dealer with respect to both foreign and domestic securities will generally include a “spread,” which is the difference between the prices at which the dealer is willing to purchase and sell the specific security at the time, and includes the dealer’s normal profit.

IPOs of securities may be over-subscribed and subsequently trade at a premium in the secondary market. When BFA is given an opportunity to invest in such an initial offering or “new” or “hot” issue, the supply of securities available for client accounts is often less than the amount of securities the accounts would otherwise take. In order to allocate these investments fairly and equitably among client accounts over time, each portfolio manager or a member of his or her respective investment team will indicate to BFA’s trading desk their level of interest in a particular offering with respect to eligible clients’ accounts for which that team is responsible. IPOs of U.S. equity securities will be identified as eligible for particular client accounts that are managed by portfolio teams who have indicated interest in the offering based on market capitalization of the issuer of the security and the investment mandate of the client account and in the case of international equity securities, the country where the offering is taking place and the investment mandate of the client account. Generally, shares received during the IPO will be allocated among participating client accounts within each investment mandate on a pro rata basis. This pro rata allocation may result in a Fund receiving less of a particular security than if pro-rating had not occurred. All allocations of securities will be subject, where relevant, to share minimums established for accounts and compliance constraints. In situations where supply is too limited to be allocated among all accounts for which the investment is eligible, portfolio managers may rotate such investment opportunities among one or more accounts so long as the rotation system provides for fair access for all client accounts over time. Other allocation methodologies that are considered by BFA to be fair and equitable to clients may be used as well.

Because different accounts may have differing investment objectives and policies, BFA may buy and sell the same securities at the same time for different clients based on the particular investment objective, guidelines and strategies of those accounts. For example, BFA may decide that it may be entirely appropriate for a growth fund to sell a security at the same time a value fund is buying that security. To the extent that transactions on behalf of more than one client of BFA or the other Affiliates during the same period may increase the demand for securities being purchased or the supply of securities being sold, there may be an adverse effect on price. For example, sales of a security by BlackRock on behalf of one or more of its clients may decrease the market price of such security, adversely impacting other BlackRock clients that still hold the security. If purchases or sales of securities arise for consideration at or about the same time that would involve the Funds or other clients or funds for which BFA or another Affiliate act as investment manager, transactions in such securities will be made, insofar as feasible, for the respective funds and clients in a manner deemed equitable to all.

Portfolio turnover may vary from year to year, as well as within a year. High turnover rates may result in comparatively greater brokerage expenses. The iShares India 50 ETF may also incur interest expenses arising from borrowings related to the acquisition of portfolio securities.

The table below sets forth the portfolio turnover rates of each Fund for the fiscal years noted:

Fund	Fiscal Year ended March 31, 2018	Fiscal Year ended March 31, 2017

iShares International Dividend Growth ETF	42%	42% ¹
iShares Latin America 40 ETF	16%	13%

¹ The portfolio turnover for iShares International Dividend Growth ETF relates to the period of May 17, 2016 to March 31, 2017 and is not annualized.

Creation or redemption transactions, to the extent consisting of cash, may require the Funds to contemporaneously transact with broker-dealers for purchases of Deposit Securities (as defined below under Fund Deposit) or sales of Fund Securities (as defined below under Redemption of Creation Units), as applicable. Such transactions with a particular broker-dealer may be conditioned upon the broker-dealers agreement to transact at guaranteed price levels in order to reduce transaction costs the Funds would otherwise incur as a consequence of settling creation or redemption baskets in cash rather than in-kind.

Following the Funds' receipt of an order to purchase or redeem creation or redemption baskets, to the extent such purchases or redemptions consist of a cash portion, the Funds will enter an order with a broker or dealer to purchase or sell the Deposit Securities or Fund Securities, as applicable. The terms of such order may, depending on the timing of the transaction and certain other factors, require the broker or dealer to guarantee that the Funds will achieve execution of their order at a price at least as favorable to the Funds as the Funds' valuation of the Deposit Securities/Fund Securities used for purposes of calculating the NAV applied to the creation or redemption transactions giving rise to the orders (the “Execution Performance Guarantee”). Such orders may be placed with the purchasing or redeeming Authorized Participant in its capacity as a broker-dealer, with its affiliated broker-dealer or with a third-party broker-dealer. The amount payable to the Funds in respect of any Execution Performance Guarantee will depend on the results achieved by the executing firm and will vary depending on market activity, timing and a variety of other factors.

To ensure that an Execution Performance Guarantee will be honored on orders arising from creation transactions executed by an Authorized Participant or its affiliate as broker-dealer, an Authorized Participant is required to deposit an amount with the Funds (the “Execution Performance Deposit”). If the broker-dealer executing the order achieves executions in market transactions at a price equal to or more favorable than the Funds' valuation of the Deposit Securities, the Funds receive the benefit of the favorable executions and returns to the Authorized Participant the Execution Performance Deposit. If, however, the broker-dealer executing the order is unable to achieve executions in market transactions at a price at least equal to the Funds' valuation of the securities, the Funds retain the portion of the Execution Performance Deposit equal to the full amount of the execution shortfall (including any taxes, brokerage, commissions or other costs) and may require the Authorized Participant to deposit any additional amount required to cover the full amount of the actual Execution Performance Guarantee.

To ensure that an Execution Performance Guarantee will be honored for brokerage orders arising from redemption transactions executed by an Authorized Participant or its affiliate as broker-dealer, an Authorized Participant agrees to pay the shortfall amount (the “Execution Performance Offset”). If the broker-dealer executing the order achieves executions in market transactions at a price equal to or more favorable than the Funds' valuation of the Fund Securities, the Funds receive the benefit of the favorable executions and the Authorized Participant is not called upon to honor the Execution Performance Offset. If, however, the broker-dealer is unable to achieve executions in market transactions at a price at least equal to the Funds' valuation of the securities, the Funds will be entitled to the portion of the Execution Performance Offset equal to the full amount of the execution shortfall (including any taxes, brokerage commissions or other costs).

The circumstances under which the Execution Performance Guarantee will be used and the expected amount, if any, of any Execution Performance Deposit or Execution Performance Offset for the Funds will be disclosed in the procedures handbook for Authorized Participants and may change from time to time based on the actual experience of the Funds.

Additional Information Concerning the Trust

Shareholders may make inquiries by writing to iShares Trust, c/o BlackRock Investments, LLC, 1 University Square Drive, Princeton, NJ 08540.

Absent an applicable exemption or other relief from the SEC or its staff, beneficial owners of more than 5% of the shares of a fund may be subject to the reporting provisions of Section 13 of the 1934 Act and the SEC’s rules promulgated thereunder. In addition, absent an applicable exemption or other relief from the SEC or its staff, officers and trustees of a fund and beneficial owners of 10% of the shares of a fund (“Insiders”) may be subject to the insider reporting, short-swing profit and short sale provisions of Section 16 of the 1934 Act and the SEC’s rules promulgated thereunder. Beneficial owners and Insiders should consult with their own legal counsel concerning their obligations under Sections 13 and 16 of the 1934 Act and existing guidance provided by the SEC staff.

In accordance with the Trust's current Agreement and Declaration of Trust (the “Declaration of Trust”), the Board may, without shareholder approval (unless such shareholder approval is required by the Declaration of Trust or applicable law, including the 1940 Act), authorize certain funds to merge, reorganize, consolidate, sell all or substantially all of their assets, or take other similar actions with, to or into another fund. The Trust or a Fund may be terminated by a majority vote of the Board, subject to the affirmative vote of a majority of the shareholders of the Trust or such Fund entitled to vote on termination; however, in certain circumstances described in the Declaration of Trust, only a majority vote of the Board is required. Although the shares are not automatically redeemable upon the occurrence of any specific event, the Declaration of Trust provides that the Board will have the unrestricted power to alter the number of shares in a Creation Unit. Therefore, in the event of a termination of the Trust or a Fund, the Board, in its sole discretion, could determine to permit the shares to be redeemable in aggregations smaller than Creation Units or to be individually redeemable. In such circumstance, the Trust or a Fund may make redemptions in-kind, for cash or for a combination of cash or securities. Further, in the event of a termination of the Trust or a Fund, the Trust or a Fund might elect to pay cash redemptions to all shareholders, with an in-kind election for shareholders owning in excess of a certain stated minimum amount.

DTC as Securities Depository for Shares of the Funds. Shares of each Fund are represented by securities registered in the name of DTC or its nominee and deposited with, or on behalf of, DTC.

DTC was created in 1973 to enable electronic movement of securities between its participants (“DTC Participants”), and NSCC was established in 1976 to provide a single settlement system for securities clearing and to serve as central counterparty for securities trades among DTC Participants. In 1999, DTC and NSCC were consolidated within The Depository Trust & Clearing Corporation (“DTCC”) and became wholly-owned subsidiaries of DTCC. The common stock of DTCC is owned by the DTC Participants, but NYSE and FINRA, through subsidiaries, hold preferred shares in DTCC that provide them with the right to elect one member each to the DTCC board of directors. Access to the DTC system is available to entities, such as banks, brokers, dealers and trust companies, that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly (“Indirect Participants”).

Share distributions shall be made to DTC or its nominee, Cede & Co., as the registered holder of all shares of the Trust. DTC or its nominee, upon receipt of any such distributions, shall credit immediately DTC Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in shares of each Fund as shown on the records of DTC or its nominee. Payments by DTC Participants to Indirect Participants and Beneficial Owners of shares held through such DTC Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a “street name,” and will be the responsibility of such DTC Participants.

brokerage transactions, privately negotiated trades, block sales, entry into options or other derivatives transactions or through any other means authorized by applicable law. Selling Shareholders may redeem the shares held in Creation Unit size by them through an Authorized Participant.

Any Selling Shareholder and any other person participating in such distribution will be subject to applicable provisions of the 1934 Act and the rules and regulations thereunder.

Creation and Redemption of Creation Units

General. The Trust issues and sells shares of each Fund only in Creation Units on a continuous basis through the Distributor or its agent, without a sales load, at a price based on each Fund's NAV next determined after receipt, on any Business Day (as defined below), of an order received by the Distributor or its agent in proper form. On days when the applicable Listing Exchange closes earlier than normal, a Fund may require orders to be placed earlier in the day. The following table sets forth the number of shares of a Fund that constitute a Creation Unit for such Fund and the approximate value of such Creation Unit as of April 30, 2018:

Fund	Shares Per Creation Unit	Approximate Value Per Creation Unit (U.S.$)
iShares Asia 50 ETF	50,000	$3,398,500
iShares Emerging Markets Infrastructure ETF	50,000	1,584,500
iShares Global Healthcare ETF¹	50,000	2,776,000
iShares Global Materials ETF	50,000	3,431,000
iShares Global Tech ETF	50,000	7,885,500
iShares Global Timber & Forestry ETF	60,000	4,824,600
iShares India 50 ETF	50,000	1,807,000
iShares International Dividend Growth ETF	50,000	2,848,000
iShares Latin America 40 ETF	250,000	9,175,000

¹ The approximate value per creation unit for the iShares Global Healthcare ETF is as of May 2, 2018.

Fund Deposit. The consideration for purchase of Creation Units of each Fund (except for the iShares India 50 ETF, which is generally offered in Creation Units solely for cash) generally consists of Deposit Securities and the Cash Component computed as described below. Together, the Deposit Securities and the Cash Component constitute the “Fund Deposit,” which, when combined with a Fund's portfolio securities, is designed to generate performance that has a collective investment profile similar to that of the Underlying Index. The Fund Deposit represents the minimum initial and subsequent investment amount for a Creation Unit of any Fund.

expenses payable upon transfer of beneficial ownership of the Deposit Securities are the sole responsibility of the Authorized Participant purchasing a Creation Unit.

The iShares India 50 ETF’s current policy is to accept cash in substitution for the Deposit Securities it might otherwise accept as in-kind consideration for the purchase of Creation Units. The Fund may, at times, elect to receive Deposit Securities (i.e., the in-kind deposit of a designated portfolio of securities) and a Cash Component as consideration for the purchase of Creation Units. If the Fund elects to accept Deposit Securities, a purchaser’s delivery of the Deposit Securities together with the Cash Component will constitute the “Fund Deposit,” which will represent the consideration for a Creation Unit of the Fund. All other Funds discussed in this SAI generally offer Creation Units partially for cash, but may, in certain circumstances, offer Creation Units solely for cash. Please see the Cash Purchase Method section below and the following discussion summarizing the Deposit Security method for further information on purchasing Creation Units of the Funds.

BFA makes available through the NSCC on each Business Day prior to the opening of business on the Listing Exchange, the list of names and the required number of shares of each Deposit Security and the amount of the Cash Component to be included in the current Fund Deposit (based on information as of the end of the previous Business Day for each Fund). Such Fund Deposit is applicable, subject to any adjustments as described below, to purchases of Creation Units of shares of the Fund until such time as the next-announced Fund Deposit is made available.

Cash Purchase Method. Although the Trust does not generally permit partial or full cash purchases of Creation Units of its funds, when partial or full cash purchases of Creation Units are available or specified for a Fund (Creation Units of the iShares India 50 ETF are generally offered solely for cash, while Creation Units of all other Funds in this SAI are generally offered partially for cash), they will be effected in essentially the same manner as in-kind purchases thereof. In the case of a partial or full cash purchase, the Authorized Participant must pay the cash equivalent of the Deposit Securities it would otherwise be required to provide through an in-kind purchase, plus the same Cash Component required to be paid by an in-kind purchaser. The Authorized Participant will also be required to pay certain transaction fees and charges for cash purchases, as described below, and, if transacting as broker with each Fund, may be required to cover certain brokerage, tax, foreign exchange, execution and price movement costs through an Execution Performance Guarantee, as described in the Brokerage Transactions section of this SAI.

next determined after receipt of the purchase order in proper form, together with the transaction fees described below. An Authorized Participant, acting on behalf of an investor, may require the investor to enter into an agreement with such Authorized Participant with respect to certain matters, including payment of the Cash Component. Investors who are not Authorized Participants must make appropriate arrangements with an Authorized Participant. Investors should be aware that their particular broker may not be a DTC Participant or may not have executed an Authorized Participant Agreement and that orders to purchase Creation Units may have to be placed by the investor's broker through an Authorized Participant. As a result, purchase orders placed through an Authorized Participant may result in additional charges to such investor. The Trust does not expect to enter into an Authorized Participant Agreement with more than a small number of DTC Participants. A list of current Authorized Participants may be obtained from the Distributor. The Distributor has adopted guidelines regarding Authorized Participants’ transactions in Creation Units that are made available to all Authorized Participants. These guidelines set forth the processes and standards for Authorized Participants to transact with the Distributor and its agents in connection with creation and redemption transactions. In addition, the Distributor may be appointed as the proxy of the Authorized Participant and may be granted a power of attorney under its Authorized Participant Agreement.

The Authorized Participant is responsible for any and all expenses and costs incurred by a Fund, including any applicable cash amounts, in connection with any purchase order.

Timing of Submission of Purchase Orders. An Authorized Participant must submit an irrevocable order to purchase shares of a Fund generally before 4:00 p.m., Eastern time on any Business Day in order to receive that day's NAV. Creation Orders must be transmitted by an Authorized Participant in the form required by the Funds to the Distributor or its agent pursuant to procedures set forth in the Authorized Participant Agreement. Economic or market disruptions or changes, or telephone or other communication failure, may impede the ability to reach the Distributor or its agent or an Authorized Participant. Orders to create shares of a Fund that are submitted on the Business Day immediately preceding a holiday or a day (other than a weekend) when the equity markets in the relevant non-U.S. market are closed may not be accepted. Each Fund's deadline specified above for the submission of purchase orders is referred to as that Fund's “Cutoff Time.” The Distributor or its agent, in their discretion, may permit the submission of such orders and requests by or through an Authorized Participant at any time (including on days on which the Listing Exchange is not open for business) via communication through the facilities of the Distributor's or its agent's proprietary website maintained for this purpose. Purchase orders and redemption requests, if accepted by the Trust, will be processed based on the NAV next determined after such acceptance in accordance with a Fund's Cutoff Times as provided in the Authorized Participant Agreement and disclosed in this SAI.

Acceptance of Orders for Creation Units. Subject to the conditions that (i) an irrevocable purchase order has been submitted by the Authorized Participant (either on its own or another investor's behalf) and (ii) arrangements satisfactory to the Funds are in place for payment of the Cash Component and any other cash amounts which may be due, the Funds will accept the order, subject to each Fund's right (and the right of the Distributor and BFA) to reject any order until acceptance, as set forth below.

In addition, the iShares India 50 ETF may exercise its right to reject any creation order for shares of the Fund on any Business Day that is a holiday in the Indian market, but not a holiday observed in the U.S. equity market, and certain other holidays during the settlement cycle for Fund shares, in order to protect Fund shareholders from any dilutive costs that may be associated with the purchase of Deposit Securities in connection with creation orders on such days.

the number of shares of each security in the Deposit Securities and the validity, form, eligibility and acceptance for deposit of any securities to be delivered shall be determined by each Fund and the Fund's determination shall be final and binding.

Costs Associated with Creation Transactions. A standard creation transaction fee is imposed to offset the transfer, processing and other transaction costs associated with the issuance of Creation Units. The standard creation transaction fee is charged on each Creation Unit created by an Authorized Participant on the day of the transaction. The standard creation transaction fee is generally fixed at the amount shown in the table regardless of the number of Creation Units being purchased, but may be reduced by each Fund if transfer and processing expenses associated with the creation are anticipated to be lower than the stated fee. If a purchase consists of a cash portion, the Authorized Participant may also be required to pay an additional transaction charge (up to the maximum amount shown below) to cover brokerage and certain other costs related to the creation transaction (which may, in certain instances, be based on a good faith estimate of transaction costs). Authorized Participants will also bear the costs of transferring the Deposit Securities to the Funds. Certain fees/costs associated with creation transactions may be waived in certain circumstances. Investors who use the services of a broker or other financial intermediary to acquire Fund shares may be charged a fee for such services.

The following table sets forth each Fund's standard creation transaction fees and maximum additional charge (as described above):

Fund	Standard Creation Transaction Fee	Maximum Additional Charge for Creations¹
iShares Asia 50 ETF²	$2,500	7.0%
iShares Emerging Markets Infrastructure ETF²	250	7.0%
iShares Global Healthcare ETF	700	3.0%
iShares Global Materials ETF	1,700	3.0%
iShares Global Tech ETF²	1,400	7.0%
iShares Global Timber & Forestry ETF	300	3.0%
iShares India 50 ETF	2,500	3.0%
iShares International Dividend Growth ETF	8,400	7.0%
iShares Latin America 40 ETF	450	3.0%

¹	As a percentage of the net asset value per Creation Unit.
²	The Maximum Additional Charge for Creations for each of the iShares Asia 50 ETF, iShares Emerging Markets Infrastructure ETF and iShares Global Tech ETF is as of July 20, 2016.

If a purchase consists of a cash portion and each Fund places a brokerage transaction to purchase portfolio securities with the Authorized Participant or its affiliated broker-dealer, the Authorized Participant (or its affiliated broker-dealer) may be required, in its capacity as broker-dealer with respect to that transaction, to cover certain brokerage, tax, foreign exchange, execution, and price movement costs through an Execution Performance Guarantee, as described in the Brokerage Transactions section of this SAI.

The iShares India 50 ETF generally redeems Creation Units solely for cash. However, the Fund reserves the right to distribute securities in-kind as payment for Creation Units being redeemed. All other Funds discussed in this SAI generally redeem Creation Units partially for cash. However, the Funds reserve the right to distribute securities and other portfolio instruments in kind as payment for Creation Units being redeemed. Please see the Cash Redemption Method section below and the following discussion summarizing the in-kind method for further information on redeeming Creation Units of the Funds.

With respect to each Fund, BFA makes available through the NSCC, prior to the opening of business on the Listing Exchange on each Business Day, the designated portfolio of securities (including any portion of such securities for which cash may be

substituted) that will be applicable (subject to possible amendment or correction) to redemption requests received in proper form (as defined below) on that day (“Fund Securities”), and an amount of cash (the “Cash Amount,” as described below). Such Fund Securities and the corresponding Cash Amount (each subject to possible amendment or correction) are applicable, in order to effect redemptions of Creation Units of a Fund until such time as the next announced composition of the Fund Securities and Cash Amount is made available. Fund Securities received on redemption may not be identical to Deposit Securities that are applicable to creations of Creation Units. Procedures and requirements governing redemption transactions are set forth in the handbook for Authorized Participants and may change from time to time.

The Trust may, in its sole discretion, substitute a “cash in lieu” amount to replace any Fund Security. The Trust also reserves the right to permit or require a “cash in lieu” amount in certain circumstances, including circumstances in which: (i) the delivery of a Fund Security to the Authorized Participant would be restricted under applicable securities or other local laws; or (ii) the delivery of a Fund Security to the Authorized Participant would result in the disposition of the Fund Security by the Authorized Participant due to restrictions under applicable securities or other local laws, or in certain other situations. The amount of cash paid out in such cases will be equivalent to the value of the substituted security listed as a Fund Security. In the event that the Fund Securities have a value greater than the NAV of the shares, a compensating cash payment equal to the difference is required to be made by or through an Authorized Participant by the redeeming shareholder. The iShares India 50 ETF generally redeems Creation Units generally for cash. All other Funds discussed in this SAI generally redeem Creation Units partially for cash. Each Fund may, in its sole discretion, provide such redeeming Authorized Participant a portfolio of securities that differs from the exact composition of the Fund Securities, but does not differ in NAV.

Cash Redemption Method. Although the Trust does not generally permit full cash redemptions of Creation Units of its funds, when partial or full cash redemptions of Creation Units are available or specified (e.g., Creation Units of the iShares India 50 ETF are generally redeemed solely for cash, while Creation Units of all other Funds in this SAI are generally redeemed partially for cash), they will be effected in essentially the same manner as in-kind redemptions thereof. In the case of partial or full cash redemption, the Authorized Participant receives the cash equivalent of the Fund Securities and other instruments it would otherwise receive through an in-kind redemption, plus the same Cash Amount to be paid to an in-kind redeemer. The Authorized Participant will also be required to pay certain transaction fees and charges for cash redemptions, as described below, and, if transacting as broker with each Fund, may be required to cover certain brokerage, tax, foreign exchange, execution and price movement costs through an Execution Performance Guarantee, as described in the Brokerage Transactions section of this SAI.

Costs Associated with Redemption Transactions. A standard redemption transaction fee is imposed to offset transfer, processing and other transaction costs that may be incurred by the relevant Fund. The standard redemption transaction fee is charged on each Creation Unit redeemed by an Authorized Participant on the day of the transaction. The standard redemption transaction fee is generally fixed at the amount shown in the table regardless of the number of Creation Units being redeemed, but may be reduced by each Fund if transfer and processing expenses associated with the redemption are anticipated to be lower than the stated fee. If a redemption consists of a cash portion, the Authorized Participant may also be required to pay an additional transaction charge (up to the maximum amount shown below) to cover brokerage and certain other costs related to the redemption transaction. Authorized Participants will also bear the costs of transferring the Fund Securities from a Fund to their account on their order. Certain fees/costs associated with redemption transactions may be waived in certain circumstances. Investors who use the services of a broker or other financial intermediary to dispose of Fund shares may be charged a fee for such services.

The following table sets forth each Fund's standard redemption transaction fees and maximum additional charge (as described above):

Fund	Standard Redemption Transaction Fee	Maximum Additional Charge for Redemptions*
iShares Asia 50 ETF	$2,500	2.0%
iShares Emerging Markets Infrastructure ETF	250	2.0%

Fund	Standard Redemption Transaction Fee	Maximum Additional Charge for Redemptions*
iShares Global Healthcare ETF	700	2.0%
iShares Global Materials ETF	1,700	2.0%
iShares Global Tech ETF	1,400	2.0%
iShares Global Timber & Forestry ETF	300	2.0%
iShares India 50 ETF	2,500	2.0%
iShares International Dividend Growth ETF	8,400	2.0%
iShares Latin America 40 ETF	450	2.0%

^*	As a percentage of the net asset value per Creation Unit, inclusive of the standard redemption transaction fee.

If a redemption consists of a cash portion and each Fund places a brokerage transaction to sell portfolio securities with the Authorized Participant or its affiliated broker-dealer, the Authorized Participant (or its affiliated broker-dealer) may be required, in its capacity as broker-dealer with respect to that transaction, to cover certain brokerage, tax, foreign exchange, execution, and price movement costs through an Execution Performance Guarantee, as described in the Brokerage Transactions section of this SAI.

For the iShares Asia 50 ETF, iShares Global Healthcare ETF, iShares Global Materials ETF and iShares Global Tech ETF, deliveries of redemption proceeds are generally made within two Business Days (i.e., “T+2”). For the iShares Emerging Markets Infrastructure ETF, iShares Global Timber & Forestry ETF, iShares India 50 ETF, iShares International Dividend Growth ETF and iShares Latin America 40 ETF, deliveries of redemption proceeds are generally made within three Business Days (i.e., “T+3”). However, each Fund reserves the right to settle redemption transactions on a basis other than T+2 or T+3, including a shorter settlement period, if necessary or appropriate under the circumstances and compliant with applicable law. For example, each Fund reserves the right to settle redemption transactions on a basis other than T+2 or T+3 in order to accommodate non-U.S. market holiday schedules (as discussed in Appendix B to this SAI), to account for different treatment among non-U.S. and U.S. markets of dividend record dates and dividend ex-dates (i.e., the last date the holder of a security can sell the security and still receive dividends payable on the security sold) and in certain other circumstances. Appendix B of this SAI identifies the instances, if any, where more than seven days would be needed to deliver redemption proceeds. Pursuant to an order of the SEC, the Trust will make delivery of redemption proceeds within the number of days stated in Appendix B of this SAI to be the maximum number of days necessary to deliver redemption proceeds.

If neither the redeeming Beneficial Owner nor the Authorized Participant acting on behalf of such redeeming Beneficial Owner has appropriate arrangements to take delivery of Fund Securities in the applicable non-U.S. jurisdiction and it is not possible to make other such arrangements, or if it is not possible to effect deliveries of Fund Securities in such jurisdiction, a Fund may in its discretion exercise its option to redeem such shares in cash, and the redeeming Beneficial Owner will be required to receive its redemption proceeds in cash. In such case, the investor will receive a cash payment equal to the net asset value of its shares based on the NAV of the relevant Fund next determined after the redemption request is received in proper form (minus a redemption transaction fee and additional charges specified above to offset the Fund's brokerage and other transaction costs associated with the disposition of Fund Securities). Redemptions of shares for Fund Securities will be subject to compliance with applicable U.S. federal and state securities laws and each Fund (whether or not it otherwise permits cash redemptions) reserves the right to redeem Creation Units for cash to the extent that the Fund cannot lawfully deliver specific Fund Securities upon redemptions or cannot do so without first registering the Fund Securities under such laws.

Although the Trust does not ordinarily permit cash redemptions of Creation Units (except that, as noted above, Creation Units of each Fund generally will be redeemed partially for cash, with the exception Creation Units of the iShares India 50 ETF, which generally will be redeemed for cash), in the event that cash redemptions are permitted or required by the Trust, proceeds will be paid to the Authorized Participant redeeming shares as soon as practicable after the date of redemption (within seven calendar days thereafter, except for the instances listed in Appendix B to this SAI in which more than seven calendar days would be needed).

To the extent contemplated by an Authorized Participant's agreement with the Distributor or its agent, in the event an Authorized Participant has submitted a redemption request in proper form but is unable to transfer all or part of the Creation Unit to be redeemed to a Fund, at or prior to 10:00 a.m., Eastern time on the Listing Exchange business day after the date of submission of such redemption request, the Distributor or its agent will accept the redemption request in reliance on the undertaking by the Authorized Participant to deliver the missing shares as soon as possible. Such undertaking shall be secured by the Authorized Participant's delivery and maintenance of collateral consisting of cash, in U.S. dollars in immediately available funds, having a value at least equal to 105% and up to 115%, which percentage BFA may change at any time, in its sole discretion, of the value of the missing shares. Such cash collateral must be delivered no later than the time specified by a Fund or its custodian on the day after the date of submission of such redemption request and shall be held by State Street and marked-to-market daily. The fees of State Street and any sub-custodians in respect of the delivery, maintenance and redelivery of the cash collateral shall be payable by the Authorized Participant. The cash collateral posted by the Authorized Participant may be invested at the risk of the Authorized Participant, and income, if any, on invested cash collateral will be paid to that Authorized Participant. The Authorized Participant Agreement permits the Funds to acquire shares of the Funds at any time and subjects the Authorized Participant to liability for any shortfall between the aggregate of the cost to the Funds of purchasing such shares, plus the value of the Cash Amount, and the value of the cash collateral together with liability for related brokerage and other charges.

Taxes

The following is a summary of certain material U.S. federal income tax considerations regarding the purchase, ownership and disposition of shares of a Fund. This summary does not address all of the potential U.S. federal income tax consequences that may be applicable to a Fund or to all categories of investors, some of which may be subject to special tax rules. Current and prospective shareholders are urged to consult their own tax advisors with respect to the specific U.S. federal, state, local and non-U.S. tax consequences of investing in a Fund. The summary is based on the laws and judicial and administrative interpretations thereof in effect on the date of this SAI, all of which are subject to change, possibly with retroactive effect.

Tax reform legislation commonly known as the Tax Cuts and Jobs Act (the “Tax Act”) was enacted on December 22, 2017. The Tax Act makes significant changes to the U.S. federal income tax rules for individuals and corporations, generally effective for taxable years beginning after December 31, 2017. Most of the changes applicable to individuals are temporary and, without further legislation, will not apply after 2025. The application of certain provisions of the Tax Act is uncertain, and the changes in the act may have indirect effects on a Fund, its investments and its shareholders that cannot be predicted. In addition, legislative, regulatory or administrative changes could be enacted or promulgated at any time, either prospectively or with retroactive effect. Prospective investors should consult their tax advisors regarding the implications of the Tax Act on their investment in a Fund.

Although, in general, the passive loss rules of the Internal Revenue Code do not apply to RICs, such rules do apply to a RIC with respect to items attributable to interests in qualified publicly-traded partnerships. A Fund's investments in partnerships, including in qualified publicly-traded partnerships, may result in the Fund being subject to state, local, or non-U.S. income, franchise or withholding tax liabilities.

Taxation of U.S. Shareholders. Dividends and other distributions by a Fund are generally treated under the Internal Revenue Code as received by the shareholders at the time the dividend or distribution is made. However, any dividend or distribution declared by a Fund in October, November or December of any calendar year and payable to shareholders of record on a specified date in such a month shall be deemed to have been received by each shareholder on December 31 of such calendar year and to have been paid by the Fund not later than such December 31, provided such dividend is actually paid by the Fund during January of the following calendar year.

101

treated for U.S. federal income tax purposes as receiving a distribution in an amount equal to the amount of money that the shareholders receiving cash dividends or distributions will receive and should have a cost basis in the shares received equal to such amount.

Investors considering buying shares just prior to a dividend or capital gain distribution should be aware that, although the price of shares purchased at that time may reflect the amount of the forthcoming distribution, such dividend or distribution may nevertheless be taxable to them. If a Fund is the holder of record of any security on the record date for any dividends payable with respect to such security, such dividends will be included in the Fund’s gross income not as of the date received but as of the later of (a) the date such security became ex-dividend with respect to such dividends (i.e., the date on which a buyer of the security would not be entitled to receive the declared, but unpaid, dividends); or (b) the date the Fund acquired such security. Accordingly, in order to satisfy its income distribution requirements, a Fund may be required to pay dividends based on anticipated earnings, and shareholders may receive dividends in an earlier year than would otherwise be the case.

In certain situations, a Fund may, for a taxable year, defer all or a portion of its net capital loss (or if there is no net capital loss, then any net long-term or short-term capital loss) realized after October and its late-year ordinary loss (defined as the sum of (i) the excess of post-October foreign currency and passive foreign investment company (“PFIC”) losses over post-October foreign currency and PFIC gains and (ii) the excess of post-December ordinary losses over post-December ordinary income) until the next taxable year in computing its investment company taxable income and net capital gain, which will defer the recognition of such realized losses. Such deferrals and other rules regarding gains and losses realized after October (or December) may affect the tax character of shareholder distributions.

If a shareholder incurs a sales charge in acquiring shares of a Fund, disposes of those shares within 90 days and then, on or before January 31 of the following calendar year, acquires shares in a mutual fund for which the otherwise applicable sales charge is reduced by reason of a reinvestment right (e.g., an exchange privilege), the original sales charge will not be taken into account in computing gain/loss on the original shares to the extent the subsequent sales charge is reduced. Instead, the disregarded portion of the original sales charge will be added to the tax basis of the newly acquired shares. Furthermore, the same rule also applies to a disposition of the newly acquired shares made within 90 days of the second acquisition. This provision prevents shareholders from immediately deducting the sales charge by shifting their investments within a family of mutual funds.

102

a basis in the securities different from the market value of such securities on the date of deposit. If a Fund’s basis in such securities on the date of deposit was less than market value on such date, the Fund, upon disposition of the securities, would recognize more taxable gain or less taxable loss than if its basis in the securities had been equal to market value. It is not anticipated that the Trust will exercise the right of rejection except in a case where the Trust determines that accepting the order could result in material adverse tax consequences to a Fund or its shareholders. The Trust also has the right to require information necessary to determine beneficial share ownership for purposes of the 80% determination.

Taxation of Certain Derivatives. A Fund’s transactions in zero coupon securities, non-U.S. currencies, forward contracts, options and futures contracts (including options and futures contracts on non-U.S. currencies), to the extent permitted, will be subject to special provisions of the Internal Revenue Code (including provisions relating to “hedging transactions” and “straddles”) that, among other consequences, may affect the character of gains and losses realized by the Fund (i.e., may affect whether gains or losses are ordinary or capital), accelerate recognition of income to the Fund and defer Fund losses. These rules could therefore affect the character, amount and timing of distributions to shareholders. These provisions also (a) will require a Fund to mark-to-market certain types of the positions in its portfolio (i.e., treat them as if they were closed out at the end of each year) and (b) may cause a Fund to recognize income without receiving cash with which to pay dividends or make distributions in amounts necessary to satisfy the distribution requirements for avoiding income and excise taxes. Each Fund will monitor its transactions, will make the appropriate tax elections and will make the appropriate entries in its books and records when it acquires any zero coupon security, non-U.S. currency, forward contract, option, futures contract or hedged investment in order to mitigate the effect of these rules and prevent disqualification of a Fund as a RIC.

103

before the date on which the shares become ex-dividend with respect to such dividend or a Fund fails to satisfy those holding period requirements with respect to the securities it holds that paid the dividends distributed to the shareholder (or, in the case of certain preferred stocks, the holding requirement of 91 days during the 181-day period beginning on the date that is 90 days before the date on which the stock becomes ex-dividend with respect to such dividend); (ii) a Fund or the shareholder is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to substantially similar or related property; or (iii) the shareholder elects to treat such dividend as investment income under Section 163(d)(4)(B) of the Internal Revenue Code. Dividends received by a Fund from a REIT or another RIC may be treated as qualified dividend income only to the extent the dividend distributions are attributable to qualified dividend income received by such REIT or other RIC. In addition, the Tax Act permits a direct REIT shareholder to claim a 20% “qualified business income” deduction for ordinary REIT dividends, but does not permit a RIC paying dividends attributable to such income to pass through this special treatment to its shareholders. Unless future legislation or regulations provide for a pass-through, investors in such a RIC will treat such distributions as ordinary dividend income, as under prior law, whereas a direct REIT investor would benefit from the special treatment. It is expected that dividends received by a Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income. Distributions by a Fund of its net short-term capital gains will be taxable as ordinary income.

Corporate Dividends Received Deduction. Dividends paid by a Fund that are attributable to dividends received by the Fund from U.S. corporations may qualify for the U.S. federal dividends received deduction for corporations. A 46-day minimum holding period during the 90-day period that begins 45 days prior to ex-dividend date (or 91-day minimum holding period during the 180 period beginning 90 days prior to ex-dividend date for certain preference dividends) during which risk of loss may not be diminished is required for the applicable shares, at both the Fund and shareholder level, for a dividend to be eligible for the dividends received deduction. Restrictions may apply if indebtedness, including a short sale, is attributable to the investment.

Issues Related to India and Mauritius Taxes. The following discussion does not address the effect on investors, including residents of India and citizens of India (whether or not residing in India or other countries, including the U.S.), of holding shares of the iShares India 50 ETF. Investors should consult their own tax advisors as to these issues based upon their own personal situations.

Indian tax matters discussed herein are based on the provisions of the IT Act, the provisions of the DTAA and other laws currently in force as of the date of this SAI. All such laws and the DTAA are subject to prospective and retroactive legislative amendment, administrative rulings and judicial review.

The iShares India 50 ETF invests in India through the Subsidiary. For U.S. federal income tax purposes, the Subsidiary has elected to be treated as an entity disregarded from its owner. Thus, for U.S. federal tax purposes, any income or loss realized by the Subsidiary will be treated as realized by the applicable fund . Therefore, any investment made by each Fund into the Subsidiary and any distributions received by the Fund from the Subsidiary are disregarded for U.S. federal tax purposes. Furthermore, there is no tax on each Fund's investment in the Subsidiary or on distributions made from the Subsidiary to the Fund .

No investor in the iShares India 50 ETF will be subject to taxation in India unless such investor is a resident of India or, if a non-resident, has an Indian source income or income received (whether accrued or otherwise) in India or triggers the indirect transfer provisions (discussed below). The IT Act provides for the concept of POEM for the determination of the residency of a foreign company. Accordingly, a company would be said to be resident in India if its POEM is situated in India. POEM is defined as a place where the key management and commercial decisions that are necessary for the conduct of the business of an entity as a whole are, in substance made. The taxation of the Subsidiary and the Fund in India is governed by the provisions of the IT Act, read with the provisions of the DTAA. As per Section 90(2) of the IT Act, the provisions of the IT Act would apply to the extent they are more beneficial than the provisions of the DTAA. In order to claim the beneficial provisions of the DTAA, the Subsidiary must be a tax resident of Mauritius.

An investor is required to submit a TRC as issued in the country of residence and provide other documents and information as prescribed by the Government to claim benefits under the DTAA.

The Subsidiary has been incorporated in Mauritius and has obtained its TRC from the Mauritius authorities that establishes its residency in Mauritius under the DTAA. The TRC must be renewed annually. The iShares India 50 ETF expects the Subsidiary to maintain its Mauritius tax residency, but it cannot be assured that the Mauritius authorities will successfully

104

renew its TRC annually or that it will continue to be eligible to the DTAA benefits, particularly in light of the new requirements that may be introduced if the DTAA is re-negotiated.

The Subsidiary holds a Category 1 Global Business License issued by the Financial Services Commission of Mauritius. The Subsidiary is subject to tax in Mauritius on its net income at the rate of 15%. However, a system of foreign tax credits which allows a tax credit against Mauritian taxes for foreign tax on a Mauritian entity’s foreign source income effectively reduces the Mauritius income tax rate to a maximum of 3% because the system presumes, in the absence of evidence, that the foreign tax paid is equal to 80% of the Mauritian tax. Further, the Subsidiary is not subject to capital gains tax in Mauritius nor is it subject to tax in Mauritius on any gains from the sale of securities. Any dividends paid by the Subsidiary to the iShares India 50 ETF will also be exempt from tax in Mauritius.

The DTAA gives India the right to tax capital gains that arise from alienation of shares of an Indian company acquired by a Mauritian tax resident. However, the DTAA also provides for grandfathering of investments in shares made before April 1, 2017. Returns from investments in shares made on or after April 1, 2017 will be subject to capital gains tax in India, although the DTAA provides for a limitation of benefits provision which shall be a prerequisite for a reduced rate of tax (50% of domestic tax rate) on capital gains arising during a two year transition period from April 1, 2017 to March 31, 2019.

The Subsidiary will attempt to abide by the requirements of the DTAA, to maintain its residency in Mauritius, and to ensure that management and control of the Subsidiary remain in Mauritius. Any change in the applicability of the provisions of the DTAA or in its applicability to the Subsidiary could result in the Subsidiary and indirectly the iShares India 50 ETF being subject to Indian income taxes, withholding taxes, and other taxes, as well as being subject to administrative or judicial assertion of such tax liabilities by the tax authorities of India. This could significantly reduce the return of the Fund on its investments in shares and the return received by Fund shareholders.

The Subsidiary is expected to have income in the form of capital gains, income from dividends and income from interest. The Indian tax consequences for the Subsidiary on account of the application of the DTAA, read with the provisions of the IT Act, would be as follows (the rates are inclusive of the highest applicable surcharges):

•

Capital gains resulting from the sale of Indian securities (including depositary receipts issued by Indian companies) acquired prior to April 1, 2017 will not be subject to tax in India, provided the Subsidiary does not have a Permanent Establishment in India. Capital gains resulting from sale of shares in Indian companies acquired on or after April 1, 2017 will be subject to tax in India as per the domestic tax rates (provided below). If the Subsidiaries are able to satisfy the conditions under the limitation of benefits article, capital gains on shares acquired on or after April 1, 2017 and sold prior to April 1, 2019 may be taxed at 50% of the applicable Indian tax rate;

•	Dividends on shares received from an Indian company on which dividend distribution tax has been paid are exempt from tax in the hands of the shareholders. However, the Indian company distributing dividends is subject to a dividend distribution tax at the rate of 20.36%; and

•

Interest paid to the Subsidiary in respect of the debt obligations of Indian issuers will be subject to Indian income tax. The tax rate, in the case of rupee-denominated debt obligations, is 43.68%. However if the Subsidiary is a SEBI registered foreign portfolio investor, interest income earned from June 1, 2013 to June 30, 2020 on rupee-denominated bonds of Indian companies and Government securities, will be subject to tax at the rate of 5.46%, provided that the rate of interest does not exceed the prescribed rates. In the case of foreign currency-denominated debt obligations, the tax rate is 21.84%. For approved foreign currency loans advanced from July 1, 2012 to June 30, 2020, the tax rate on interest is 5.46% and for approved foreign currency long-term bonds issued from October 1, 2014 to June 30, 2020, the tax rate on interest is 5.46%. As per the IT Act the withholding tax rate on rupee-denominated bonds issued before July 1, 2020 to 5.46%. The Protocol provides for a withholding rate of 7.5% on the interest payments made on or after April 1, 2017.

In the event that the benefits of the DTAA are not available to the Subsidiary, taxation of dividend income of the Subsidiary would be the same as described above, however, the reduced interest withholding rate under the DTAA, will not be available.

In view of the provisions of the IT Act, since the Subsidiary is a SEBI registered foreign portfolio investor, the gains arising from transfer of securities would be characterized as “capital gains” and not business income. The taxation of capital gains under the IT Act would be as follows, assuming total income will be more than INR 100 million:

•	Long-term capital gains (being gains on sale of shares held for a period of more than twelve months) listed on a recognized stock exchange would be taxable in India at rate of 10.92%, provided Securities Transaction Tax (“STT”)

105

	has been paid, both on acquisition and sale (subject to certain transactions to which the provisions of applicability of payment of STT upon acquisition shall not be applicable) of such shares. Capital gains tax would be calculated on gains exceeding INR 0.1 million (without any indexation and foreign exchange fluctuation benefits). It may also be noted that any capital gains arising up to January 31, 2018 have been grandfathered;
•	Short-term capital gains (being gains on sale of shares held for a period of twelve months or less) from the sale of Indian shares listed on a recognized stock exchange will be taxed at the rate of 16.38% provided STT has been paid on the same;
•	Long-term capital gains (being gains on sale of shares held for a period of more than 24 months) arising to the Subsidiary from the sale of unlisted securities will be taxed at the rate of 10.92% (without indexation) and short-term capital gains (being gains on sale of shares held for a period of 24 months or less) will be taxed at the rate of 43.68%;*
•	Capital gains realized on sale of listed equity shares not executed on a recognized stock exchange in India would be taxed at the rate of 10.92% for long-term gains (being gains on sale of shares held for a period of more than 12 months) and at 43.68% in the case of short-term gains (being gains on sale of shares held for a period of 12 months or less);* and

•	Capital gains arising from the transfer of depositary receipts outside India between non-resident investors will not be subject to tax in India.

*	However, as the Subsidiary is a SEBI registered foreign portfolio investor, the rates will be 10.92% and 32.76%, respectively.

As per current provisions, gains arising from transfer of securities to foreign portfolio investor will be regarded as capital gains and will be taxable at the aforesaid rates.

Indian Minimum Alternate Tax

The question of whether foreign companies (which would include FIIs) are liable for MAT has been a subject matter of controversy in India. Under the MAT provisions, in the event a company’s tax liability is less than 18.5% of its book profits, then instead of paying income tax at rates provided otherwise under the IT Act, the company is liable to pay MAT on the adjusted book profits at the rate of 21.55% (inclusive of applicable taxes and surcharges, assuming total income of more than INR 100 million).

The IT Act provides that MAT is not applicable on foreign company where the foreign company is a resident of a country with which India has signed a DTAA and the foreign company does not have a permanent establishment in India in accordance with such DTAA.

Indian Securities Transaction Tax

All transactions entered on a recognized stock exchange in India are subject to an STT. STT has been introduced under Section 98 of the Finance (No.2) Act, 2004 on transactions relating to sale, purchases and redemption of shares made by purchasers or sellers of Indian securities and equity oriented mutual fund units. The current STT as levied on the transaction value as follows:

•	0.1% payable by the buyer and 0.1% by the seller on the value of transactions of delivery based transfer of an equity share in an Indian company entered in a recognized stock exchange;
•	0.001% on the value of transactions of delivery based sale of a unit of an equity oriented mutual fund entered in a recognized stock exchange, payable by the seller;
•	0.025% on the value of transactions of non-delivery based sale of an equity share in an Indian company or a unit of an equity oriented mutual fund, entered in a recognized stock exchange payable by the seller;
•	0.05% on the value of transactions of derivatives being options, entered in a recognized stock exchange. STT is to be paid by the seller;
•	0.01% on the value of transactions of sale of derivatives being futures, entered in a recognized stock exchange. STT is to be paid by the seller;
•	0.001% on the value of transactions of sale of units of an equity-oriented fund to the Mutual Fund, payable by the seller in accordance with the Finance Act, 2013;

106

•	0.125% on the value of transactions of sale of derivatives being options, where the option is exercised, entered in a recognized stock exchange. STT is to be paid by buyer;

•	0.2% on the value of transactions of the sale of unlisted shares by existing shareholders in an initial public offer.

The foregoing is based upon current interpretation and practice and is subject to future changes in the tax laws of India or Mauritius and in the DTAA. Any change in the DTAA's application could have a material adverse effect on the returns of the iShares India 50 ETF. Further, it is possible that the Indian tax authorities may seek to take the position that the Fund is not entitled to the benefits of the DTAA.

Indirect Transfers

The current legislation imposes Indian tax and withholding obligations with respect to the transfer of shares and interest in an overseas company that derives its value substantially from assets situated in India (indirect transfers). It has been clarified that Indian tax authorities will not reopen any assessment proceedings that were completed before April 1, 2012 and where no notice for reassessment has been issued prior to that date. The CBDT also clarified that any assessment or any other order which stands validated due to the amendments in the Finance Act would be enforced. Given this clarification issued by the CBDT, the Funds does not expect that shareholders or the Funds will become subject to tax or to withholding obligations with respect to completed assessments.

It has been clarified that the share or interest of the foreign entity shall be deemed to derive its value substantially from the assets located in India, if the value of such Indian assets exceeds INR 100 million, and represents at least 50% of the value of all the assets owned by the foreign entity. The value of an asset shall be the fair market value as of the specified date, of such an asset without reduction of liabilities. The fair market value will be determined in accordance with the Rule 11UB of the IT Rules. It has been provided that where all the assets of the foreign entity are not located in India, only such part of the income as is reasonably attributable to the Indian assets shall be subject to capital gains tax in India.

Further, it provides exemption from indirect transfer provisions to the small shareholders of such foreign entity in the following cases:

•

The IT Act provides that aforesaid indirect transfer provisions will not apply to foreign investors making an investment directly or indirectly in a SEBI registered Category I and Category II foreign portfolio investor.

Under IT Act, gains realized when a non-resident acquires shares of a foreign company from another non-resident and the foreign company derives “substantial value” from Indian assets, (meaning that the value of Indian assets (i) exceeds INR 100 million, and (ii) represents at least 50% of the value the company’s assets), such gains are taxable in India and subject to withholding, to the extent that they are reasonably attributable to the Indian assets.

Because the Fund invests in Indian securities through the Subsidiary, the Subsidiary or the Fund may be considered to derive “substantial value” from Indian assets. Accordingly, shareholder redemptions of Fund/Subsidiary shares and sales of Fund shares may have been subject to Indian tax and withholding obligations. However, the IT Act provides for an exemption to shareholders in Category I and Category II FPI from the applicability of indirect transfer taxation. The Subsidiary is a Category

107

II FPI. Therefore, any redemptions or transfers by the Fund or the shareholders in the Fund should not be subject to Indian indirect transfer tax.

General Anti-Avoidance Rules.

The GAAR introduced in the IT Act provides the Indian tax authorities a mechanism to deny any tax benefits in a transaction or any other arrangement that is believed to not have any commercial substance or purpose other than to obtain tax benefit(s) under a treaty. The provisions of GAAR will be applicable to arrangements (including a step in or a part thereof) entered into by a taxpayer, which may be declared as an “impermissible avoidance arrangement”.

CBDT has clarified that where a FPI (such as the Subsidiary) is located in a particular jurisdiction based on non-tax commercial reasons and the main purpose of the choice of location/residence of the FPI is not to obtain a treaty benefit, the GAAR provisions will not be resorted to by the tax authorities.

As per the provisions of the IT Rules, GAAR shall not apply in the following circumstances:

•	any arrangement where the aggregate tax benefit to all the parties of the arrangement in the relevant financial year does not exceed INR 30 Million;
•	FIIs that choose not to take any benefit under any tax treaty entered with India and have invested in listed or unlisted securities with prior permission of the competent authority in accordance with the applicable regulations;
•	non-resident investor in an FII who has invested in an FII, directly or indirectly, by way of an offshore derivative instrument or otherwise; or

•	any income derived from the transfer of shares or interests made prior to April 1, 2017.

If the iShares India 50 ETF's use of the Subsidiary were considered to be such an impermissible avoidance arrangement, the Fund may become subject directly to taxation in India. The burden of proof in enforcing the rule will reside with the Indian government, not the taxpayer, and India’s current double tax treaty arrangements will remain in force. However, GAAR may, irrespective of existing treaty provisions, lead to the imposition of tax liabilities and withholding obligations, which may lead the Fund to modify the structure.

Recent amendments to DTAA and GAAR could change the manner in which the Subsidiary are currently taxed in India and could adversely impact the returns to the iShares India 50 ETF/Subsidiary and their respective shareholders. The Funds will continue to monitor developments in India with respect to these matters. Investors are urged to consult their own tax advisers with respect to their own tax situations and the tax consequences of an investment in each of the Funds.

108

certain non-U.S. currency options or futures contracts denominated in non-U.S. currency, to the extent attributable to fluctuations in exchange rates between the acquisition and disposition dates, are also treated as ordinary income or loss unless a Fund was to elect otherwise.

A Fund will make the appropriate tax elections, if possible, and take any additional steps that are necessary to mitigate the effects of these rules.

Other Taxes. Dividends, distributions and redemption proceeds may also be subject to additional state, local and non-U.S. taxes depending on each shareholder’s particular situation.

Distributions that a Fund reports as “short-term capital gain dividends” or “long-term capital gain dividends” will not be treated as such to a recipient foreign shareholder if the distribution is attributable to gain received from the sale or exchange of U.S. real property or an interest in a U.S. real property holding corporation and the Fund’s direct or indirect interests in U.S. real property exceeded certain levels. Instead, if the foreign shareholder has not owned more than 5% of the outstanding shares of a Fund at any time during the one year period ending on the date of distribution, such distributions will be subject to 30% withholding by the Fund and will be treated as ordinary dividends to the foreign shareholder; if the foreign shareholder owned more than 5% of the outstanding shares of the Fund at any time during the one year period ending on the date of the distribution, such distribution will be treated as real property gain subject to 21% withholding tax and could subject the foreign shareholder to U.S. filing requirements. Additionally, if a Fund’s direct or indirect interests in U.S. real property were to exceed certain levels, a foreign shareholder realizing gains upon redemption from the Fund could be subject to the 21% withholding tax and U.S. filing requirements unless more than 50% of the Fund’s shares were owned by U.S. persons at such time or unless the foreign person had not held more than 5% of the Fund’s outstanding shares throughout either such person’s holding period for the redeemed shares or, if shorter, the previous five years.

generally must be treated by such foreign shareholders as income effectively connected to a trade or business within the U.S., which is generally subject to tax at the graduated rates applicable to U.S. shareholders, except for distributions to foreign shareholders that held no more than 5% of any class of stock of the Fund at any time during the previous one-year period ending on the date of the distributions. Such distributions may be subject to U.S. withholding tax and may require a foreign shareholder to file a U.S. federal income tax return. In addition, sales or redemptions of shares held by certain foreign shareholders in such a Fund generally will be subject to U.S. withholding tax and generally will require the foreign shareholder to file a U.S. federal income tax return, although exceptions may apply if more than 50% of the value of the Fund’s shares are held by U.S. shareholders or the foreign shareholder selling or redeeming the shares has held no more than 5% of any class of stock of the Fund at any time during the five-year period ending on the date of the sale or redemption.

Shares of a Fund held by a non-U.S. shareholder at death will be considered situated within the U.S. and subject to the U.S. estate tax.

INTRODUCTION TO BLACKROCK

PHILOSOPHY ON CORPORATE GOVERNANCE

CORPORATE GOVERNANCE, ENGAGEMENT AND VOTING

A-3

principles inform our voting decisions in relation to specific resolutions that may appear on the agenda of a shareholder meeting in the relevant market.

The six key themes are:

•	Boards and directors
•	Auditors and audit-related issues
•	Capital structure, mergers, asset sales and other special transactions
•	Remuneration and benefits
•	Social, ethical and environmental issues
•	General corporate governance matters

Boards and directors

We expect the board of directors to promote and protect shareholder interests by:

•	establishing an appropriate corporate governance structure;
•	supporting and overseeing management in setting strategy;
•	ensuring the integrity of financial statements;
•	making decisions regarding mergers, acquisitions and disposals;
•	establishing appropriate executive compensation structures; and
•	addressing business issues including social, ethical and environmental issues when they have the potential to materially impact company reputation and performance.

•	current employment at the company or a subsidiary;

A-4

•	former employment within the past several years as an executive of the company;
•	providing substantial professional services to the company and/or members of the company’s management;

Oversight

BlackRock’s Equity Policy Oversight Committee (EPOC) is informed of certain aspects of the work of the Global Corporate Governance Oversight Committee and the Corporate Governance Group.

A-7

Conflicts management

•	BlackRock has adopted a proxy voting oversight structure whereby the Corporate Governance Committees oversee the voting decisions and other activities of the Corporate Governance Group, and particularly its activities with respect to voting in the relevant region of each Corporate Governance Committee’s jurisdiction.
•	The Corporate Governance Committees have adopted Guidelines for each region, which set forth the firm’s views with respect to certain corporate governance and other issues that typically arise in the proxy voting context. The Corporate Governance Committees receive periodic reports regarding the specific votes cast by the Corporate Governance Group and regular updates on material process issues, procedural changes and other matters of concern to the Corporate Governance Committees.
•	BlackRock’s Global Corporate Governance Oversight Committee oversees the Global Head, the Corporate Governance Group and the Corporate Governance Committees. The Global Corporate Governance Oversight Committee conducts a review, at least annually, of the proxy voting process to ensure compliance with BlackRock’s risk policies and procedures.
•	BlackRock maintains a reporting structure that separates the Global Head and Corporate Governance Group from employees with sales responsibilities. In addition, BlackRock maintains procedures intended to ensure that all engagements with corporate issuers or dissident shareholders are managed consistently and without regard to BlackRock’s relationship with the issuer of the proxy or dissident shareholder. Within the normal course of business, the Global Head or Corporate Governance Group may engage directly with BlackRock clients, and with employees with sales responsibilities, in discussions regarding general corporate governance policy matters, and to otherwise ensure that proxy-related client service levels are met. The Global Head or Corporate Governance Group does not discuss any specific voting matter with a client prior to the disclosure of the vote decision to all applicable clients after the shareholder meeting has taken place, except if the client is acting in the capacity as issuer of the proxy or dissident shareholder and is engaging through the established procedures independent of the client relationship.
•	In certain instances, BlackRock may determine to engage an independent fiduciary to vote proxies as a further safeguard to avoid potential conflicts of interest or as otherwise required by applicable law. The independent fiduciary may either vote such proxies or provide BlackRock with instructions as to how to vote such proxies. In the latter case, BlackRock votes the proxy in accordance with the independent fiduciary’s determination. Use of an independent fiduciary has been

A-8

adopted for voting the proxies related to any company that is affiliated with BlackRock or any company that includes BlackRock employees on its board of directors.

Appendix B - Regular Holidays and Redemptions

The securities delivery cycles currently practicable for transferring portfolio securities to redeeming investors, coupled with non-U.S. market holiday schedules, will require a delivery process longer than seven calendar days, in certain circumstances. The holidays applicable to each Fund during such periods are listed below, as are instances where more than seven days will be needed to deliver redemption proceeds. Although certain holidays may occur on different dates in subsequent years, the number of days required to deliver redemption proceeds in any given year is not expected to exceed the maximum number of days listed below for each Fund. The proclamation of new holidays, the treatment by market participants of certain days as “informal holidays” (e.g., days on which no or limited securities transactions occur, as a result of substantially shortened trading hours), the elimination of existing holidays, or changes in local securities delivery practices, could affect the information set forth herein in the future.

In calendar year 2018 (the only year for which holidays are known at the time of filing of this SAI), the dates of regular holidays affecting the relevant securities markets in which a Fund invests are as follows (please note that these holiday schedules are subject to potential changes in the relevant securities markets):

The Trust (also referred to in this section as the “Fund”) is organized as a Delaware statutory trust and is operated pursuant to an Amended and Restated Agreement and Declaration of Trust (the “Declaration of Trust”) that permits the Trust to indemnify its trustees and officers under certain circumstances. Such indemnification, however, is subject to the limitations imposed by the Securities Act of 1933, as amended (the “1933 Act”), and the Investment Company Act of 1940, as amended (the “1940 Act”). The Declaration of Trust provides that officers and trustees of the Trust shall be indemnified by the Trust to the fullest extent permitted by law against liability and against all expenses reasonably incurred or paid in connection with any claim, action, suit, proceeding in which he or she becomes involved as a party or otherwise by virtue of being or having been a trustee or officer and against amounts paid as incurred in the settlement thereof. This indemnification is subject to the following conditions:

(a) no trustee or officer of the Trust is indemnified against any liability to the Trust or its security holders, as adjudicated by a court or body before which the proceeding was brought, that was the result of any willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of his office; and

(b) as adjudicated by a court or body before which the proceeding was brought, officers and trustees of the Trust are indemnified only for actions taken in good faith that the officers and trustees reasonably believed were in or not opposed to the best interests of the Trust.

The Declaration of Trust provides that if indemnification is not ordered by a court, indemnification may be authorized by a majority vote of a quorum of the trustees who were not parties to the proceedings or, if this quorum is not obtainable, if directed by a quorum of disinterested trustees, or by independent legal counsel in a written opinion, that the persons to be indemnified have met the applicable standard; provided, however, that any shareholder, by appropriate legal proceedings, may challenge any such determination by the trustees or by independent legal counsel.

Article IX of the Registrant’s Amended and Restated By-Laws provides as follows:

The Amended and Restated By-Laws provides that the Trust may purchase and maintain insurance on behalf of any Covered Person or employee of the Trust, including any Covered Person or employee of the Trust who is or was serving at the request of the Trust as a trustee, officer, or employee of a corporation, partnership, association, joint venture, trust, or other enterprise, against any liability asserted against and incurred by such Covered Person or employee in any such capacity or arising out of his or her status as such, whether or not the trustees would have the power to indemnify him or her against such liability. The Trust may not acquire or obtain a contract for insurance that protects or purports to protect any trustee or officer of the Trust against any liability to the Trust or its Shareholders to which such trustee or officer otherwise would be subject by reason of willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of his or her office.

Insofar as indemnification for liabilities arising under the 1933 Act may be permitted to directors, officers and controlling persons of the Fund pursuant to the foregoing provisions, or otherwise, the Fund has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the 1933 Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Fund of expenses incurred or paid by a director, officer or controlling person of the Fund in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Fund will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the 1933 Act and will be governed by the final adjudication of such issue.

Section 17.1 of the Master Services Agreement between Registrant and State Street provides as follows:

The Master Services Agreement provides that State Street will indemnify, defend and hold harmless the applicable Fund, its Affiliates, and its respective officers, directors, employees, agents and permitted successors and assigns from any and all damages, fines, penalties, deficiencies, losses, liabilities (including judgments and amounts reasonably paid in settlement) and expenses (including interest, court costs, reasonable fees and expenses of attorneys, accountants and other experts or other reasonable fees and expenses of litigation or other proceedings or of any claim, default or assessment) (“Losses”) arising from or in connection with any third party claim or threatened third party claim to the extent that such Losses are based on or arising out of any of the following: (a) breach by State Street or any State Street Personnel of any of its data protection, information security or confidentiality obligations hereunder or under a Service Module to which such Fund is a signatory; (b) any claim of infringement or misappropriation of any Intellectual Property Right alleged to have occurred because of systems or other Intellectual Property provided by or on behalf of State Street or based upon the performance of the Services (collectively, the “State Street Infringement Items”), except to the extent that such infringement or misappropriation relates to or results from; (i) changes made by any Fund or by a third party at the direction of a Fund to the State Street Infringement Items; (ii) changes to the State Street Infringement Items recommended by State Street and not made due to a request from any Fund, provided that State Street has notified such Fund that failure to implement such recommendation would result in infringement within a reasonable amount of time for such Fund to so implement following such notification; (iii) any Fund’s combination of the State Street Infringement Items with products or services not provided or approved in writing by State Street, except to the extent such combination arises out of any Fund’s use of the State Street Infringement Items in a manner consistent with the applicable business requirements documentation; (iv) designs or specifications that in themselves infringe and that are provided by or at the direction of any Fund (except in the event of a knowing infringement by State Street); or (v) use by a Fund of any of the State Street Infringement Items in a manner that is not consistent with the applicable business requirements documentation or otherwise not permitted under the Master Services Agreement or any Service Module; (c) any claim or action by, on behalf of, or related to, any prospective, then-current or former employees of State Street, arising from or in connection with a Service Module to which a Fund is a signatory, including: (i) any claim arising under occupational health and safety, worker’s compensation, ERISA or other applicable Law; (ii) any claim arising from the interview or hiring practices, actions or omissions of employees of State Street; (iii) any claim relating to any violation by employees of State Street, or its respective officers, directors, employees, representatives or agents, of any Law or any common law protecting persons or members of protected classes or categories, such laws or regulations prohibiting discrimination or harassment on the basis of a protected characteristic; and (iv) any claim based on a theory that such Fund is an employer or joint employer of any such prospective, then-current or former employees of State Street; (d) the failure by State Street to obtain, maintain, or comply with any governmental approvals as required under the Master Services Agreement and/or a Service Module to which such Fund is a signatory or such other failures as otherwise agreed by the Parties from time to time; (e) claims by third parties arising from claims by governmental authorities against such Customer for fines, penalties, sanctions, late fees or other remedies to the extent arising from or in connection with State Street’s failure to perform its responsibilities under the Master Services Agreement or any Service Module (except to the extent a Fund is not permitted as a matter of public policy to have such an indemnity for financial penalties arising from criminal actions); (f) claims by clients of State Street relating to services, products or systems provided by State Street or a Subcontractor to such client(s) in a shared or leveraged environment; (g) any claim initiated by an Affiliate or potential or actual Subcontractor of State Street asserting rights in connection with a Service Module to which such Fund is a signatory; or (h) other claims as otherwise agreed by the Parties from time to time.

Section 8.02 of the Distribution Agreement between Registrant and BRIL provides as follows:

The Distribution Agreement provides that BRIL agrees to indemnify and hold harmless the Trust, each of its trustees, officers, employees and each person, if any, who controls the Trust within the meaning of Section 15 of the 1933 Act (collectively, the “Trust Indemnified Parties”) from and against any and all losses to which the Trust Indemnified Parties become subject, arising out of or based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading, in reliance upon and in conformity with written information furnished to the Trust by BRIL about BRIL expressly for use therein; (ii) any breach of any representation, warranty or covenant made by BRIL in the Distribution Agreement; and (iii) the actions or omissions of any person acting under the supervision of BRIL in providing services under the Distribution Agreement; provided, however, that BRIL shall not be liable in any such case to the extent that any loss arises out of or is based upon (A) the Trust’s own willful misfeasance, willful misconduct or gross negligence or the Trust’s reckless disregard of its obligations under the Distribution Agreement or (B) the Trust’s material breach of the Distribution Agreement.

The Authorized Participant Agreement provides that the Authorized Participant (the “Participant”) agrees to indemnify and hold harmless the Fund and its respective subsidiaries, affiliates, directors, officers, employees and agents, and each person, if any, who controls such persons within the meaning of Section 15 of the 1933 Act (each an “Indemnified Party”) from and against any loss, liability, cost and expense (including attorneys’ fees) incurred by such Indemnified Party as a result of (i) any breach by the Participant of any provision of the Authorized Participant Agreement that relates to the Participant; (ii) any failure on the part of the Participant to perform any of its obligations set forth in the Authorized Participant Agreement; (iii) any failure by the Participant to

comply with applicable laws, including rules and regulations of self-regulatory organizations; or (iv) actions of such Indemnified Party in reliance upon any instructions issued in accordance with Annex II, III or IV (as each may be amended from time to time) of the Authorized Participant Agreement reasonably believed by the distributor and/or the transfer agent to be genuine and to have been given by the Participant.

Section 5.1(c) of the Amended and Restated Securities Lending Agency Agreement provides as follows:

The Amended and Restated Securities Lending Agency Agreement provides that BTC shall indemnify and hold harmless the Trust and each Fund, its Board of Trustees and its agents and BFA and any investment adviser for the Funds from any and all loss, liability, costs, damages, actions, and claims (“Loss”) to the extent that any such Loss arises out of the material breach of this Agreement by or negligent acts or omissions or willful misconduct of BTC, its officers, directors or employees or any of its agents or subcustodians in connection with the securities lending activities undertaken pursuant to this Agreement, provided that BTC’s indemnification obligation with respect to the acts or omissions of its subcustodians shall not exceed the indemnification provided by the applicable subcustodian to BTC.
