iSHARES^® COMMODITY MULTI-STRATEGY ETF

Ticker: ____

Stock Exchange: _________

Investment Objective

The iShares Commodity Multi-Strategy ETF (the “Fund”) seeks to provide exposure, on a total return basis, to a group of commodities with characteristics of carry, momentum, and value.

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 U.S. ETF 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, commodities or other financial instruments and the execution of portfolio transactions, including brokerage commissions, distribution fees or expenses, litigation expenses and any extraordinary 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
___%	None	None	___%

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
	$__		$__

S-1

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it, directly or indirectly through a subsidiary, buys and sells securities or other assets (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.

Principal Investment Strategies

The Fund is actively managed and seeks to achieve its investment objective in part by investing in a broad range of derivative instruments, including total return swaps that provide exposure to commodities futures contracts referenced by the _____________ (the “___________ Benchmark”). The Fund intends to follow a multifactor strategy reflected by the ___________ Benchmark, which equally weights three sub-indices designed to provide exposure to carry, momentum, and value factors.

commodity by the ratio of its 3-month average spot price to its 5-year average (the “Value Ratio”). Sector weights are held constant versus a broad non-factor-weighted commodity index, but within each sector, commodities with the lowest Value Ratio are overweighted relative to commodities with higher Value Ratios.

In order to maintain exposure to a futures contract on a particular commodity, an investor must sell the position in the expiring contract and buy a new position in a contract with a later delivery month, which is referred to as “rolling.” If the price for the new futures contract is less than the price of the expiring contract, then the market for the commodity is said to be in “backwardation.” In these markets, roll returns are positive, which is referred to as “positive carry.” The term “contango” is used to describe a market in which the price for a new futures contract is more than the price of the expiring contract. In these markets, roll returns are negative, which is referred to as “negative carry.” The ________ Benchmark seeks to employ a positive carry strategy for each of the carry, momentum, and value factors that emphasizes commodities and futures contract months in order to maximize backwardation and minimize contango, with the goal of generating net gains through positive roll returns.

S-2

and value strategies by entering into total return swaps that pay the returns of the commodity futures contracts referenced from time to time in the _________ Benchmark. The ___________ Benchmark includes the 22 futures contracts on physical agricultural, energy, precious metals, and industrial metals listed on the U.S. regulated futures exchanges.

The Fund is expected to establish new swaps contracts on an ongoing basis and replace expiring contracts. Swaps subsequently acquired by the Fund may have terms that differ from the swaps the Fund previously held. In its total return swaps, the Fund generally pays a fixed payment rate and swap-related fees to the counterparty and receives the total return of the _______ Benchmark, including in the event of negative performance by the _________ Benchmark, a negative return (i.e., a payment from the Fund to the swap counterparty). In seeking total return, the Fund additionally aims to generate interest income and capital appreciation through a cash management strategy consisting primarily of cash and cash equivalents, short-term government obligations, and short-term investment-grade fixed-income securities (collectively, “Fixed-Income Investments”). While the Fund will invest in financial instruments that reference the _________ Benchmark and commodities through its subsidiary (described below), the Fund also expects to engage in the cash management strategy through direct holdings by the Fund.

The Fund is an actively managed exchange-traded fund (“ETF”) and does not seek to replicate the performance of a specified index. While the Fund is not an index fund, the Fund's

investment strategy seeks to maximize correlation with the _______ Benchmark and many of the Fund’s swap investments provide returns that are linked to the ________ Benchmark.

The Fund may also invest in swaps on commodity futures contracts that are not included in the _________ Benchmark but are similar to those found in the _______ Benchmark, as well as in futures and options that correlate to the investment returns of commodities without investing directly in physical commodities, and over-the-counter commodity-linked instruments such as commodity-linked notes and forward contracts (together the “Commodity Investments”). The Fund will invest in commodity-related financial instruments solely through its subsidiary. Investing in derivative contracts may have a leveraging effect on the Fund. Although the Fund may hold swaps on, or direct investments in, the same futures contracts as those included in the _______ Benchmark, the Fund is not obligated to invest in any futures contracts included in, and does not seek to replicate the performance of, the _______ Benchmark.

The Fund seeks to gain exposure to total return swaps and other Commodity Investments by investing through a wholly-owned subsidiary organized in the Cayman Islands (the “Subsidiary”). The Subsidiary is advised by BFA and has the same investment objective as the Fund. Unlike the Fund, the Subsidiary is not an investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). The Subsidiary invests solely in Commodity Investments and cash and cash equivalents.

In compliance with Subchapter M of the

S-3

Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), the Fund may invest up to 25% of its total assets in the Subsidiary. The Fund’s Commodity Investments held in the Subsidiary are intended to provide the Fund with exposure to broad commodities consistent with current U.S. federal income tax laws applicable to investment companies such as the Fund, which limit the ability of investment companies to invest directly in Commodity Investments.

The remainder of the Fund’s assets will be invested directly by the Fund, primarily in Fixed-Income Investments, including repurchase agreements, money market instruments, U.S. government and agency securities, Treasury inflation-protected securities, sovereign debt obligations on non-U.S. countries and investment-grade corporate bonds. The Fund invests in Fixed-Income Investments for investment purposes and to provide sufficient assets to account for (or “cover”) mark-to-market changes and to collateralize the Subsidiary’s investments in derivatives.

The Commodity Futures Trading Commission (“CFTC”) has adopted certain requirements that subject registered investment companies and their advisers to regulation by the CFTC if a registered investment company invests more than a prescribed level of its net asset value in CFTC-regulated futures, options and swaps, or if a registered investment company markets itself as providing investment exposure to such instruments. Due to the Fund’s potential use of CFTC-regulated futures, options and swaps above the prescribed levels, it is considered a “commodity pool” under the Commodity Exchange Act (“CEA”).

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. Unlike many ETFs, the Fund is actively managed and is not an index-based ETF.

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

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.

S-4

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.

Carry Strategy Risk. The futures market for a commodity in which the price for a new futures contract is less than the price of an expiring contract, known as a market trading in a state of “backwardation,” may not continue to trade with the same degree of backwardation or with the resulting returns. To the extent that a commodity futures market is not trading in a state of backwardation (or is, but to a lesser degree), the Fund’s cost to maintain exposure to the commodity may increase, the positive carry strategy may prove unsuccessful, and the investment performance of the Fund may suffer.

Cash Management Risk. If a significant amount of the Fund’s assets are invested in cash and cash equivalents, the Fund may underperform other funds that do not similarly invest in cash and cash equivalents for investment purposes and/or to collateralize derivative instruments.

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 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.

Commodity-Linked Derivatives Risk. The value of a commodity-linked derivative instrument typically is based upon the price movements of the underlying commodity or an economic variable linked to such price movements. Spot prices and futures prices for commodities will vary depending upon expectations regarding market conditions. Both spot and futures prices of commodity-related investments may fluctuate quickly and dramatically as a result of changes affecting a particular commodity and may not correlate to price movements in other asset classes, such as stocks, bonds and cash. Commodity-linked derivatives are subject to the risk that the counterparty to the transaction, the exchange or trading facility on which they trade or the applicable clearing house may default or otherwise fail to perform. In addition, each exchange or trading facility on which the derivatives are traded has the right to suspend or limit trading in all futures or other instruments that it lists. The Fund’s use of commodity-linked derivatives may also have a leveraging effect on the Fund’s portfolio. Leverage generally magnifies the effect of a change in the value of an asset and creates a risk of loss of value on a larger pool of assets than the Fund would otherwise have had. The Fund is required to post margin in respect to its holdings in derivatives. Each of these factors and events could have a significant negative impact on the Fund.

S-5

Commodity Regulatory Risk. The Fund and the Subsidiary are deemed commodity pools and BFA is considered a “commodity pool operator” with respect to the Fund under the CEA. BFA is therefore subject to regulation by the SEC and the CFTC. BFA is also subject to regulation by National Futures Association (“NFA”). The regulatory requirements governing the use of commodity futures, options on commodity futures, certain swaps or certain other investments could change at any time.

Commodity Risk. The Fund has substantial exposure to commodities. The Fund invests in instruments and 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.

Counterparty Risk. Certain commodity-linked derivative instruments, uncleared swaps agreements and other forms of financial instruments that involve counterparties subject the Fund to the

risk that the counterparty could default on its obligations under the agreement, either through the counterparty’s bankruptcy or failure to perform its obligations. In the event of a counterparty default, the Fund could experience lengthy delays in recovering some or all of its assets or obtain no recovery at all and, if the counterparty is subject to specified types of resolution proceedings, the Fund may be subject to stays that limit its ability to close out positions and limit risk. The Fund’s investments in the futures markets also introduce the risk that its futures commission merchant (“FCM”) could default on an obligation set forth in an agreement between the Fund and the FCM, including the FCM’s obligation to return margin posted in connection with the Fund’s futures contracts.

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.

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

S-6

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, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Derivatives Risk. The Fund’s use of derivatives may reduce the 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. A risk of the 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.

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.

S-7

is exposed to rolling futures contracts, it may be subject to additional risk. In addition, CFTC regulations limit the types of foreign listed futures contracts that U.S. investors, like the Fund, are allowed to invest in. As a result, the Fund may not be able to gain the exposure it seeks through certain non-U.S. futures contracts.

Income Risk. The Fund's income may decline when yields fall. This decline can occur because the Fund may subsequently invest in lower-yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds are substituted, 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 or other assets to which the Fund has exposure as well as the correlation among the assets. Changes in the financial condition or credit rating of an issuer of those securities or of securities referenced by swaps or other derivatives or the seller or counterparty with respect to derivatives or other assets may cause the value of the securities, derivatives, or other assets 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.

Management Risk. The Fund is subject to management risk, which is the risk that the investment process, techniques and risk analyses applied by BFA will not produce the desired results, and that securities or assets selected by BFA may underperform the market or any relevant benchmark. In addition, legislative, regulatory, or tax developments may affect the investment techniques available to BFA in connection with managing the Fund and may also adversely affect the ability of the Fund to achieve its investment objective.

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. Unlike some ETFs that track specific indexes, the Fund does not seek to replicate the performance of a specified index. Index-based ETFs have generally traded at prices that closely correspond to NAV. However, ETFs that do not seek to replicate the performance of a specified index have a limited trading history and, therefore, there can be no assurance as to whether, and/or the extent to which, the Fund's shares will trade at premiums or discounts to NAV. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S SHARES

S-8

TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Momentum Strategy Risk. Commodities or securities that previously exhibited high momentum characteristics may not experience positive momentum or may experience more volatility than the market as a whole.

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.

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

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.

Risk of Investing in Agriculture and Livestock. Investments in the agricultural and livestock sectors may be volatile and change unpredictably as a result of many factors, such as legislative or regulatory developments relating to food safety, the imposition of tariffs or other trade restraints, and the supply and demand of each commodity. Increased competition and changes in consumer tastes and spending can also influence the demand for agricultural and livestock products, affecting the price of such commodities and the performance of the Fund.

Risk of Investing in Industrial Metals. The industrial metals sector may be adversely affected by changes in international economic and political conditions, increased competition and changes in industrial and commercial demand for industrial metals. As a result, the price of industrial metals has been subject to substantial price fluctuations over short periods of time.

Risk of Investing in the U.S. 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.

Risk of Swap Agreements. A swap is a two-party contract that generally obligates each counterparty to exchange periodic payments based on a pre-determined underlying investment or notional amount and to exchange collateral to secure the obligations of

S-9

each counterparty. Swaps may be leveraged and are subject to counterparty risk, credit risk and pricing risk. Swaps may also be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses. Certain standardized interest rate and credit default swaps are required to be traded on an exchange or trading platform and centrally cleared. Most other swaps are entered into a negotiated, bi-lateral basis and traded in the over-the-counter market. Swaps are subject to bi-lateral variation margin. Initial margin requirements are in the process of being phased in and should be effective by 2020.

Subsidiary Risk. In compliance with Subchapter M of the Internal Revenue Code, the Fund may invest up to 25% of its total assets in the Subsidiary. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this Prospectus, is not subject to the investor protections of the 1940 Act. Changes in the laws of the U.S. and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in the Prospectus and the Statement of Additional Information (“SAI”), and could adversely affect the Fund.

S-10

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.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Alan Mason and Richard Mejzak (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Mason and Mr. Mejzak have been Portfolio Managers of the Fund since inception.

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 ____ 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 specified amount of cash.

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 individual retirement account (“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.

Additional Information on Principal Investment Strategies. The Fund is an actively managed ETF and, thus, does not seek to replicate the performance of a specified index. Accordingly, the management team has discretion on a daily basis to manage the Fund's portfolio in accordance with the Fund's investment objective.

The Fund’s investment objective is a non-fundamental policy and may be changed without shareholder approval.

The Fund seeks to achieve its investment objective in part by investing in total return swaps referencing the ________ Benchmark. The Fund also seeks to generate interest income and capital appreciation through a cash management strategy consisting of investments in Fixed-Income Investments.

Investment Process.

BFA uses its discretion to determine the percentage of the Fund’s assets allocated to swaps and other Commodity Investments. Generally, BFA will take various factors into account on a periodic basis in allocating the assets of the Fund, including, but not limited to, the performance of swaps and Commodity Investments relative to each other, relative price differentials for a range of commodity futures for current delivery as compared to similar commodity futures for future delivery, and other market conditions. The weightings of the Fund’s portfolio will be reviewed and updated at least annually.

In certain situations or market conditions, the Fund may temporarily depart from its normal investment process, provided that the alternative, in the opinion of BFA, is consistent with the Fund’s investment objective and is in the best interest of the Fund. For example, the Fund may hold a higher than normal proportion of its assets in cash in response to adverse market, economic or political conditions.

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.

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.

Asset Class Risk. The securities and other assets in the Fund’s portfolio may underperform in comparison to other securities, assets or indexes that track other issuers, countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors (including the futures market). Various types of securities or assets 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.

Cash Management Risk. To the extent the Fund holds cash, the Fund will earn reduced income (if any) on the cash and will be subject to the credit risk of the depository institution holding the cash and any fees imposed on large cash balances. If a significant amount of the Fund’s assets are invested in cash and cash equivalents, the Fund may underperform other funds that do not similarly invest in cash and cash equivalents for investment purposes and/or to collateralize derivative instruments.

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.

Commodity-Linked Derivatives Risk. The value of a commodity-linked derivative instrument typically is based upon the price movements of the underlying commodity or an economic variable linked to such price movements. Therefore, the value of commodity-linked derivative instruments may be affected by changes in overall economic conditions, interest rates, or factors affecting a particular commodity or industry , such as production, disease, climate conditions, supply or demand, politics, geopolitics, changes in international balance of payments and trade, currency devaluations and revaluations, market liquidity, and economic, political and regulatory developments. Spot prices and futures prices for commodities will vary depending upon expectations regarding market conditions. Both spot and futures prices of commodity-related investments may fluctuate quickly and dramatically as a result of changes affecting a particular commodity and may or may not correlate to price movements in other asset classes, such as stocks, bonds and cash. Investments in commodity-linked derivatives may be subject to greater volatility than non-derivative based investments. A highly liquid secondary market may not exist for certain commodity-linked derivatives, and there can be no assurance that one will develop. Commodity-linked derivatives also may be subject to credit and interest rate risks that in general affect the values of fixed-income securities. Therefore, at maturity, the Fund may receive more or less principal than it originally invested. The Fund might receive interest payments that are more or less than the stated coupon interest payments. Commodity derivatives are subject to the risk that the counterparty to the transaction, the exchange or trading facility on which they trade or the applicable clearing house may default or otherwise fail to perform. In addition, each exchange or trading facility on which derivatives are traded has the right to suspend or limit trading in all futures or other instruments that it lists. The Fund’s use of commodity-linked derivatives can result in large amounts of financial leverage. Although the Fund will not borrow money in order to increase the amount of its trading, the low margin deposits normally required in futures trading permit a high degree of leverage on the investment itself. Accordingly, a relatively small price movement in a futures contract may result in immediate and substantial losses to the Fund. Like other leveraged investments, any trade may result in losses in excess of the amount invested. Each of these factors and events could have a significant negative impact on the Fund.

Commodity Regulatory Risk. The Fund and the Subsidiary are deemed “commodity pools” and BFA is considered a “commodity pool operator” with respect to the Fund under the CEA. BFA is therefore subject to regulation by the SEC and the CFTC. BFA is also subject to regulation by NFA. The regulatory requirements governing the use of commodity futures, or options on commodity futures, certain swaps or certain other investments could change at any time.

Commodity Risk. The Fund’s portfolio 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.

The commodity markets are subject to temporary distortions and other disruptions due to, among other factors, lack of liquidity, the participation of speculators, and government regulation and other actions. U.S. futures exchanges and some foreign exchanges limit the amount of fluctuation in futures contract prices that may occur in a single business day (generally referred to as “daily price fluctuation limits”). The maximum or minimum price of a contract as a result of these limits is referred to as a “limit price.” If the limit price has been reached in a particular contract, no trades may be made beyond the limit price. Limit prices have the effect of precluding trading in a particular contract or forcing the liquidation of contracts at disadvantageous times or prices.

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, representing a particular 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.

Counterparty Risk. Certain commodity-linked derivative instruments, uncleared swaps agreements and other forms of financial instruments that involve counterparties subject the Fund to the risk that the counterparty could default on its obligations under the agreement, either through the counterparty’s bankruptcy or failure to perform its obligations. In the event of a counterparty default, the Fund could experience lengthy delays in recovering some or all of its assets or obtain no recovery at all and, if the counterparty is subject to specified types of resolution proceedings, the Fund may be subject to stays that limit its ability to close out positions and limit risk. The Fund may deposit funds required to margin open positions in the derivative instruments subject to the CEA with a clearing broker, registered as an FCM, an entity that solicits or accepts orders to buy or sell commodity futures, options, swaps or forward contracts and accepts money or other assets from customers to support such orders. The FCM could default on an obligation set forth in an agreement between the Fund and the FCM, including the FCM’s obligation to return margin posted in connection with the Fund’s futures contracts. If a counterparty defaults on its payment obligations, the Fund may lose money and the value of an investment in Fund shares may decrease. In addition, the Fund may engage in such investment transactions with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk.

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.

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, market makers or Authorized Participants. The Fund and its shareholders could be negatively impacted as a result.

Derivatives Risk. The Fund’s use of derivatives may reduce the 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. A risk of the 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.

Energy Sector Risk. The energy sector may be cyclical and highly dependent on energy prices. The market value of securities 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; and energy conservation efforts, increased competition and technological advances. The energy sector may also be subject to substantial government regulation and contractual fixed pricing.

Futures Contract Risk. Futures are standardized, exchange-traded contracts that obligate a purchaser to take delivery, and a seller to make delivery, of a specific amount of an asset at a specified future date at a specified price. Unlike equities, which typically entitle the holder to a continuing ownership stake in a corporation, futures contracts normally specify a certain date for settlement in cash based on the level of the reference rate. The primary risks associated with the use of futures contracts, or swaps or other derivatives referencing futures contracts, are: (i) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the futures contract; (ii) possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (iii) losses caused by unanticipated market movements, which are potentially unlimited; (iv) BFA's inability to predict correctly the direction of prices and other economic factors; and (v) the possibility that the counterparty will default in the performance of its obligations. When a futures contract is rolled forward—which may be done in order to retain the allocation to a specific position beyond the maturity of the futures contract—the Fund may lose money if the two contracts are trading at different prices as compared to fair value. For example, if the futures contract which the Fund has exposure to and is rolling is trading at a discount to fair value and the new contract it rolls into is trading at a premium to fair value, the Fund will lose money. The actual realization of a potential roll cost will be dependent upon the difference in

price of the near and distant contract. The relevant futures contracts may not be “rolled” on a predefined schedule as they approach expiration; instead BFA may determine to gain exposure to another futures contract (chosen from a list of tradable futures that expire in the next 9 months) in an attempt to generate maximum yield. There can be no guarantee that such a strategy will produce the desired results. In addition, CFTC regulations limit the types of foreign listed futures contracts that U.S. investors, like the Fund, are allowed to invest in. As a result, the Fund may not be able to gain the exposure it seeks through certain non-U.S. futures contracts.

Income Risk. The Fund’s income may decline when yields fall because the Fund may hold a significant portion of short duration securities and/or securities that have floating or variable interest rates. The Fund’s income may decline because the Fund invests in lower yielding bonds, as bonds in its portfolio mature, are near maturity or are called, or when the Fund needs to purchase additional bonds.

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, rising interest rates may cause the value of the Fund’s investments to decline significantly. 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.

Issuer Risk. The performance of the Fund depends on the performance of individual securities or assets to which the Fund has exposure. Any issuer of these securities or assets may perform poorly, causing the value of its securities or assets 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. 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 assets, or securities or assets 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 or assets 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, especially in changing or volatile markets. 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 for 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.

Management Risk. The Fund is subject to management risk because it does not seek to replicate the performance of a specified index. BFA and the portfolio managers will utilize a proprietary investment process, techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results. In addition, legislative, regulatory, or tax developments may affect the investment techniques available to BFA in connection with managing the Fund and may also adversely affect the ability of the Fund to achieve its investment objective.

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 volatility in spot prices 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 the prices of securities, commodities, and multiple other 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, commodities and other 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.

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 their shares and the underlying value of their 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 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.

Momentum Strategy Risk. Commodities and securities that have previously exhibited high momentum characteristics may not experience positive momentum in the future or may experience more volatility than the market as a whole. BFA may be unsuccessful in implementing a strategy that emphasizes momentum commodities and securities. In addition, there may be periods when the momentum style of investing is out of favor and the investment performance of the Fund may suffer.

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.

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.

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.

Risk of Investing in Agriculture and Livestock. The agricultural and livestock sectors are subject to government subsidy policies and environmental, health and safety laws and regulations. Specific governmental policies, such as taxes, tariffs, duties, subsidies and import and export restrictions on agricultural commodities, commodity products and livestock, can influence the profitability of investing in agriculture and livestock. Import restrictions and tariffs that have recently been imposed by foreign countries on U.S. agricultural and livestock products are expected to negatively impact the profitability of investing in these products. These industries may also be adversely affected by changes in commercial and consumer demand for their products. A growing competitive landscape and increased availability of such commodities can influence: (i) the planting and raising of certain crops/livestock versus other uses of resources; (ii) the location and size of crop and livestock production; (iii) whether unprocessed or processed commodity products are traded; and (iv) the volume and types of imports and exports. Economic recession or labor difficulties, may also lead to a decrease in demand for the products and services involved in agriculture. As a result, the price of agricultural or livestock commodities could decline, which would affect the performance of the Fund.

The agricultural and livestock sectors also are particularly sensitive to changing weather conditions, such as floods or droughts, natural disasters and other factors, such as disease outbreaks and pollution.

Risk of Investing in Industrial Metals. The price of industrial metals may be adversely affected by unpredictable international economic and political policies, such as currency devaluations or revaluations, economic and social conditions within an individual country, trade imbalances, or trade or currency restrictions between countries. As a result, the price of industrial metals historically has been subject to substantial price fluctuations over short periods of time.

This sector also could be adversely affected by changes in exchange rates and inflation, imposition of import controls, increased competition, and changes in industrial and commercial demand for industrial metals as the principal supplies of metal industries may be concentrated in a small number of countries and regions.

Risk of Investing in the U.S. 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 including derivatives and Commodity Investments. 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 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 the issuers in which the Fund invests.

Risk of Swap Agreements. Swaps can involve greater risks than direct investment in securities because swaps may be leveraged and are subject to counterparty risk (e.g., the risk of a counterparty defaulting on the obligation or bankruptcy), credit risk and pricing risk (i.e., swaps may be difficult to value). Swaps may be subject to liquidity risk, and it may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses. Certain standardized interest rate and credit default swaps are required to be traded on an exchange or trading platform and centrally cleared. Most other swaps are entered into on a negotiated, bi-lateral basis and traded in the over-the-counter market. Swaps are subject to bi-lateral variation margin. Initial margin requirements are in the process of being phased in and should be effective by 2020. Central clearing is expected to reduce counterparty credit risk and increase liquidity, but central clearing does not make swap transactions risk-free. Swaps entered into by the Fund through its Subsidiary are not expected to be centrally cleared and thus will expose the Fund to counter-party default risk and liquidity risk, as liquidity depends on the willingness of counterparties to enter into, and the ability of counterparties to hedge the risks of, such contracts.

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.

Subsidiary Risk. In compliance with Subchapter M of the Internal Revenue Code, the Fund may invest up to 25% of its total assets in the Subsidiary, as determined at the end of each of the Fund’s fiscal quarters. By investing in a Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The swaps and Commodity Investments that may be held by the Subsidiary are subject to the same risks that apply to similar investments if held directly by the Fund. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in the Prospectus, is not subject to the investor protections of the 1940 Act. The Trust’s Board of Trustees (the “Board”) has oversight responsibility for the investment

activities of the Fund, including its investment in the Subsidiary, and the Fund’s role as sole shareholder of the Subsidiary. The Subsidiary’s financial statements will be consolidated with the Fund’s financial statements that are included in the Fund’s annual and semi-annual reports to shareholders.

Tax Risk. The Fund invests in commodity-linked derivatives indirectly through the Subsidiary because income from these investments, if made directly, might not be treated as “qualifying income” for purposes of the Fund qualifying as a RIC for U.S. federal income tax purposes. The Fund expects its income with respect to the Subsidiary to be qualifying income. There is a risk that the IRS could issue regulations or other guidance holding, or could assert, that the Fund’s income with respect to the Subsidiary will not be considered “qualifying income” for purposes of the Fund remaining qualified as a RIC for U.S. federal income tax purposes. In such circumstances, the Fund may be required to make changes to its operations, which may reduce the Fund’s ability to gain investment exposure to commodities. Fund shareholders may also experience adverse tax consequences in such circumstances. Moreover, changes in the laws of the U.S. and/or the Cayman Islands could result in the inability of the Fund and/or Subsidiary to operate as described in the Prospectus and in the SAI, and could adversely affect the Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains taxes, estate duty, inheritance tax, gift tax or withholding tax on the Subsidiary. If Cayman Islands law changes such that the Subsidiary must pay Cayman Islands taxes, Fund shareholders would likely experience decreased investment returns.

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, 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. 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.

Value Strategy Risk. Commodities or securities that may be perceived as undervalued may fail to appreciate for long periods of time and may never realize their full potential value. BFA may be unsuccessful in implementing a strategy that emphasizes undervalued commodities and securities. In addition, there may be periods when the value style of investing is out of favor and the investment performance of the Fund may suffer.

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. Regulations adopted by 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.

Risk of Investing in Precious Metals. Prices of precious metals and of precious metal related securities historically have been very volatile. The high volatility of precious metal prices may adversely affect the financial condition of companies involved with precious metals. The production and sale of precious metals by governments or central banks or other larger holders can be affected by various economic, financial, social and political factors, which may be unpredictable and may have a significant impact on the prices of precious metals. Other factors that may affect the prices of precious metals and securities related to them include changes in inflation, the outlook for inflation and changes in industrial and commercial demand for precious metals.

Some precious metals mining operation companies may hedge, to varying degrees, their exposure to falls in precious metals prices by selling forward future production. This may limit the company’s ability to benefit from future increases in the price of precious metals, thereby lowering returns to the Fund. Hedging techniques also have their own risk, including the possibility that a mining company or other party will be unable to meet its contractual obligations and potential margin requirements.

Other factors that may affect the prices of precious metals and securities related to them include changes in inflation, the outlook for inflation and changes in industrial and commercial demand for precious metals. Additionally, increased environmental or labor costs may depress the value of mining and metal investments.

Sovereign Obligations Risk. An investment in sovereign debt obligations involves special risks not present in corporate debt obligations. Sovereign debt includes securities issued by or guaranteed by a sovereign government. The issuer of the sovereign debt that controls the repayment of the debt may be unable or unwilling to repay principal or interest when due, and the Fund may have limited recourse in the event of a default. Similar to other issuers, changes to the financial condition or credit rating of a government may cause the value of a sovereign debt obligation, including U.S. Treasury obligations, to decline. During periods of economic uncertainty, the market prices of sovereign debt may be more volatile than prices of debt obligations and may affect the Fund's NAV. These risks may be more pronounced with respect to non-U.S. sovereign debt than with respect to U.S. government debt.

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, and derivatives such as options, swaps, and futures, 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 including derivatives such as options, swaps and futures.

U.S. Treasury Obligations Risk. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury obligations to decline. On August 5, 2011, S&P Global Ratings downgraded U.S. Treasury securities from AAA rating to AA+ rating. A further downgrade of the ratings of U.S. government debt obligations, which are often used as a benchmark for other borrowing arrangements, could result in higher interest rates for individual and corporate borrowers, cause disruptions in the international bond markets and have a substantial negative effect on the U.S. economy. A downgrade of U.S. Treasury securities from another ratings agency or a further downgrade below AA+ rating by S&P Global Ratings may cause the value of the Fund's U.S. Treasury obligations to decline.

Portfolio Holdings Information

A description of the Trust's policies and procedures with respect to the disclosure of the Fund’s portfolio securities and other assets is available in the Fund's 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 trading, research and expertise of its asset management affiliates for portfolio decisions and management with respect to portfolio securities and other assets. 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, commodities or other financial instruments 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 the avoidance of doubt, extraordinary expenses do not include expenses related to the organization of any subsidiary for the Fund or the ongoing corporate expenses of maintaining such subsidiary.

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 __%. BFA also serves as investment adviser to the Subsidiary. No fee will be paid to BFA for the advisory services that it provides to the Subsidiary. 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, Inc. (“BlackRock”). As of ___________, 2018, BFA and its affiliates provided investment advisory services for assets in excess of $___ trillion. BFA 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. BFA is considered a “commodity pool operator” with respect to the Fund under the CEA and is therefore subject to regulation by the SEC and the CFTC with respect to the Fund.

A discussion regarding the basis for the approval by the Board of the Investment Advisory Agreement with BFA will be available in the Fund's _________ report for the period ending ________.

From time to time, a manager, analyst, or other employee of BlackRock or its affiliates may express views regarding a particular asset class, company, security, industry, or market sector. The views expressed by any such person are the views of only that individual as of the time expressed and do not necessarily represent the views of BlackRock or any other person within the BlackRock organization. Any such views are subject to change at any time based upon market or other conditions and BlackRock disclaims any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for the Fund are based on numerous factors, may not be relied on as an indication of trading intent on behalf of the Fund.

Portfolio Managers. Alan Mason and Richard Mejzak 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, developing and implementing the Fund’s investment process and investment strategy, researching and reviewing investment strategy and overseeing members of his portfolio management team that have more limited responsibilities. The following information provides additional information about each portfolio manager and member of the iShares Global Investment Research Team.

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

Richard Mejzak has been with BlackRock since 1990, including his years with Merrill Lynch Investment Managers, which was acquired by BlackRock in 2006. Mr. Mejzak became a portfolio manager for BFA in 2012. Mr. Mejzak has been a Portfolio Manager of the Fund since inception.

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.

Conflicts of Interest. The investment activities of BFA and its affiliates (including BlackRock and its subsidiaries (collectively, the “Affiliates”)) and their directors, officers and employees and of The PNC Financial Services Group, Inc. (which, through a subsidiary, has a significant economic interest in BlackRock) and its subsidiaries (each with The PNC Financial Services Group, Inc., an “Entity” and collectively, the “Entities”) 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, its Affiliates and the Entities provide investment management services to other funds and discretionary managed accounts that may follow investment programs similar to that of the Fund. BFA, its Affiliates and the Entities 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 Affiliates or Entities act, 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, index provider, agent and 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 an Affiliate or an Entity 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 or an Entity has developed or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments or other interests. The Fund may also invest in issuances (such as structured notes) by entities for which an Affiliate or an Entity provides and is compensated for cash management services relating to the proceeds from the sale of such issuances. The Fund also may invest in securities of, or engage in other transactions with, companies for which an Affiliate or an Entity provides or may in the future provide research coverage. An Affiliate or an Entity may have business relationships with, and purchase, or 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 Entities in

connection with the Fund's portfolio investment transactions. BFA or one or more Affiliates or Entities 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. This may include transactions in 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 1940 Act). The trading activities of BFA and these Affiliates or Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA or an Affiliate or an Entity having positions in certain securities that are senior or junior to, or have interests different from or adverse to, the securities that are owned by the Fund.

Neither BlackRock nor any 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 or an Affiliate or an Entity or its or their directors, officers or employees or other clients have an adverse interest. Furthermore, transactions undertaken by clients advised or managed by BFA, its Affiliates or Entities may adversely impact the Fund. Transactions by one or more clients or by BFA, its Affiliates or Entities or their directors, officers or employees, 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 BFA, one or more Affiliates or Entities and/or their internal policies designed to comply with such restrictions.

The activities of BFA, its Affiliates and Entities and their respective directors, officers or employees, 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 SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

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 will be 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 “___.”

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

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 and other assets after the close of the primary markets for the Fund’s portfolio securities or assets 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 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 _________.

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 underlying securities or assets 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.

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.

Generally, trading in U.S. Treasury futures, 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 and other assets 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.

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.

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 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.

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 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. However, given the Fund's investment objective and strategies, the Fund generally does not expect its distributions to be treated as qualified dividend income. 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. Because the Fund may have a higher portfolio turnover than funds that seek to replicate the performance of an index, the Fund may, in comparison to such other funds, realize and distribute a higher amount of taxable realized capital gain. 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.

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. 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.

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 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 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.

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 ____ 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.

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.

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 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.

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.

The following table shows, as of __________, 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*
$_______		____		$___		__%		__%

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

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

Financial highlights for the Fund are not available because, as of the effective date of this Prospectus, the Fund has not commenced operations and therefore has no financial highlights to report.

General Description of the Trust and the Fund

The Trust currently consists of __ investment series or portfolios. The Trust was organized as a Delaware statutory trust on June 21, 2011 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 seeks to provide exposure, on a total return basis, to a group of commodities with characteristics of carry, momentum, and value. The Fund uses the ______________ as a benchmark to measure its investment returns (the “ _________ Benchmark”). The Fund is not an index fund and does not seek to track the performance of the _________ Benchmark. The Fund is managed by BlackRock Fund Advisors (“BFA”), an indirect wholly-owned subsidiary of BlackRock, Inc.

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 specified amount of cash. Shares of the Fund are listed for trading on _______ (the “Listing Exchange” or “_____”), 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, and, generally, in exchange for a specified amount of cash. Creation Units typically are a specified number of shares, generally ______ 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. Shares may be issued in advance of receipt of Deposit Securities (as defined in the Exchange Listing and Trading section), 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 122%, 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, or (ii) the indicative optimized portfolio value (IOPV) of the Fund 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.

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, deposit of a specified cash payment (the “Cash Component”) and a component based on other assets held by the Fund. The equity securities values included in an IOPV are the values of a designated portfolio of securities (including any portion of such securities for which cash may be substituted) (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 or other assets held by the Fund at a particular point in time because the current portfolio of the Fund may include securities or other assets 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 may consist of other assets held by the Fund, including cash, 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 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 “carry” sub-index emphasizes commodities and contract months with the greatest degree of backwardation or lowest degree of contango. As further explained below, contango refers to when the futures price of a commodity is above its spot price. Backwardation refers to the opposite, when the spot price of a commodity is above the futures price. The “momentum” sub-index underweights or overweights commodities based on the relative strength of a commodity's performance within the last 12 months. The “value” sub-index measures value for each commodity by the ratio of its 3-month average spot price to its 5-year average (the “Value Ratio”). Sector weights are held constant versus a broad non-factor-weighted commodity index, but within each sector, commodities with the lowest Value Ratio are overweighted relative to commodities with higher Value Ratios.

The Fund expects to obtain exposure to commodities through financial instruments, entered into by a subsidiary of the Fund, which provide exposure to commodities and not in the physical commodities themselves. Although the Fund may invest in a range of financial instruments, the Fund expects to obtain a substantial amount of its exposure to the carry, momentum, and value strategies by entering into total return swaps that pay the returns of the commodity futures contracts referenced from time to time in the _________ Benchmark. The ___________ Benchmark includes the 22 futures contracts on physical agricultural, energy, precious metals, and industrial metals listed on the U.S. regulated futures exchanges.

The Fund is an actively managed exchange-traded fund (“ETF”) and does not seek to replicate the performance of a specified index. While the Fund is not an index fund, the Fund's investment strategy seeks to maximize correlation with the _________ Benchmark and many of the Fund’s swap investments provide returns that are linked to the ________ Benchmark.

The Fund seeks to gain exposure to total return swaps and other Commodity Investments by investing through a wholly-owned subsidiary organized in the Cayman Islands (the “Subsidiary”). The Subsidiary is advised by BFA and has the same investment objective as the Fund. Unlike the Fund, the Subsidiary is not an investment company registered under the 1940 Act. The Subsidiary invests solely in Commodity Investments and cash and cash equivalents.

In compliance with Subchapter M of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), the Fund may invest up to 25% of its total assets in the Subsidiary. The Fund’s Commodity Investments held in the Subsidiary are intended to provide the Fund with exposure to broad commodities consistent with current U.S. federal income tax laws applicable to investment companies such as the Fund, which limit the ability of investment companies to invest directly in Commodity Investments.

Although the Fund does not seek leveraged returns, certain instruments used by the Fund may have a leveraging effect as described below.

Investments in the Subsidiary are expected to provide the Fund with exposure to investment returns of commodities within the limitations of Subchapter M of the Internal Revenue Code, as discussed below. The Subsidiary is a company organized under the laws of the Cayman Islands, whose registered office is located at the offices of Maples Corporate Services Limited, P.O. Box 309, Ugland House, Grand Cayman KYI-1104, Cayman Islands. The Subsidiary’s affairs are overseen by a board of directors, which is comprised of Jack Gee, Treasurer and Chief Financial Officer of the Trust, and Paul Lohrey, Assistant Secretary of the Trust. The Fund is the sole shareholder of the Subsidiary, and shares of the Subsidiary will not be sold or offered to other investors.

The Subsidiary invests primarily in swaps and Commodity Investments. The Fund will gain exposure to the investment returns of commodities indirectly by investing in the Subsidiary. To the extent that BlackRock believes that such instruments provide suitable exposure to commodities, the Fund’s investment in the Subsidiary will likely increase. BlackRock manages the assets of the Subsidiary, but receives no additional compensation for doing so.

BlackRock also provides certain administrative services for the Subsidiary, but receives no additional compensation for doing so. The Subsidiary will also enter into a contract for the provision of custody, transfer agency, and accounting agent services with the same or with affiliates of the same service providers that provide those services to the Fund.

Generally, the Fund and the Subsidiary test for compliance with investment policies and restrictions, including asset segregation requirements, on a consolidated basis for 1940 Act purposes, calculated in accordance with SEC staff guidance, where applicable. For compliance with federal income tax requirements, the Fund and the Subsidiary expect to comply with the asset segregation requirements on a stand-alone basis, with instruments requiring physical settlement being classified on a market value rather than on a notional basis. The Subsidiary is also expected to comply with the other applicable 1940 Act requirements, including those related to custody and affiliated transactions.

The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in the Fund’s Prospectus or this SAI, is not subject to the investor protections of the 1940 Act. However, the Fund wholly owns and controls the Subsidiary, and the Fund and the Subsidiary are managed by BFA. The Trust’s Board of Trustees has oversight responsibility for the investment activities of the Fund, including its investment in the Subsidiary, and the Fund’s role as sole shareholder of the Subsidiary.

The Fund invests in commodity-linked derivatives indirectly through the Subsidiary because income from these investments, if made directly, might not be treated as “qualifying income” for purposes of the Fund qualifying as a regulated investment company (“RIC”) for U.S. federal income tax purposes. The Fund expects its income with respect to the Subsidiary to be qualifying income. There is a risk that the U.S. Internal Revenue Service (“IRS”) could issue regulations or other guidance holding, or could assert, that the Fund’s income with respect to the Subsidiary will not be considered “qualifying income” for purposes of the Fund remaining qualified as a RIC for U.S. federal income tax purposes. In such circumstances, the Fund may be required to make changes to its operations, which may reduce the Fund’s ability to gain investment exposure to commodities. Fund shareholders may also experience adverse tax consequences in such circumstances.

Moreover, changes in the laws of the U.S. and/or the Cayman Islands could result in the inability of the Fund and/or Subsidiary to operate as described in the Fund’s Prospectus and this SAI and could adversely affect the Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains taxes, estate duty, inheritance tax, gift tax or withholding tax on the Subsidiary. If Cayman Islands law changes such that the Subsidiary must pay Cayman Islands taxes, Fund shareholders would likely experience decreased investment returns.

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.

The purchase of securities or other assets 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.

Derivatives. The Fund will 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 or as a vehicle to obtain investment exposure to a security, commodity, currency, or index. 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 investment portfolio of such a fund. 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 RIC for purposes of 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 and Options. To the extent required by law, liquid assets committed to futures contracts will be maintained. A call option gives a holder the right to purchase a specific security or asset 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 or asset 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. Investments in futures contracts and other investments that contain leverage may require the Fund to maintain liquid assets. 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 set aside assets equal to the futures contracts’ full notional value. The Fund bases its asset maintenance policies on methods permitted by the staff of the SEC 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.

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). An illiquid investment is any investment that the Fund reasonably expects cannot be sold in seven calendar days or less without significantly changing the market value of the investment. The liquidity of a security will be determined based on relevant market, trading and investment specific considerations as set out in the Fund's liquidity risk management program (the “Liquidity Program”) as required by Rule 22e-4 under the 1940 Act (the “Liquidity Rule”). 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. If illiquid investments exceed 15% of a Fund’s net assets, the Liquidity Rule and the Liquidity Program will require that certain remedial actions be taken.

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.

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.

Options on Futures Contracts. The Fund may invest in options on futures contracts. An option on a futures contract, as contrasted with the direct investment in such a contract, gives the purchaser the right, 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.

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 in the nature of 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,” to and from the broker will be made daily as the price of the 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.

Regulation Regarding Derivatives. The CFTC subjects advisers to registered investment companies to regulation by the CFTC if a fund that is advised by the investment 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. Due to the Fund’s potential use of CFTC Derivatives above the prescribed levels, the Fund and the subsidiary will each be considered a “commodity pool” under the CEA. Accordingly, BFA, the Fund’s investment adviser, has registered as a “commodity pool operator” and is subject to CFTC regulation with respect to the Fund.

Repurchase Agreements. A repurchase agreement is an instrument under which the purchaser (i.e., the 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, 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.

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 (“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 S&P Global, Inc., a subsidiary of The McGraw-Hill Companies (“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.

Sovereign Obligations. The Fund may invest in sovereign obligations. An investment in sovereign debt obligations involves special risks not present in corporate debt obligations. Sovereign debt includes securities issued or guaranteed by a foreign sovereign government. The issuer of the sovereign debt that controls the repayment of the debt may be unable or unwilling to repay principal or interest when due, and the Fund may have limited recourse in the event of a default. Similar to other

issuers, changes to the financial condition or credit rating of a non-U.S. government may cause the value of a sovereign debt to decline. During periods of economic uncertainty, the market prices of sovereign debt obligations may be more volatile than prices of U.S. debt obligations, which may affect the Fund's NAV. Several sovereign issuers have experienced volatility and adverse trends due to concerns about rising government debt levels, including Greece, Ireland, Italy, Portugal and Spain.

A sovereign debtor's willingness or ability to repay principal and pay interest in a timely manner may be affected by, among other factors, its cash flow situation, the extent of its non-U.S. currency reserves, the availability of sufficient foreign exchange, the relative size of the debt service burden, the sovereign debtor's policy toward principal international lenders and local political constraints. Sovereign debtors may also be dependent on expected disbursements from foreign governments, multilateral agencies and other entities to reduce principal and interest arrears on their debt. The failure of a sovereign debtor to implement economic reforms, achieve specified levels of economic performance or repay principal or interest when due may result in the cancellation of third-party commitments to lend funds to the sovereign debtor, which may further impair such debtor's ability or willingness to service its debts.

Swap Agreements. Swap agreements are contracts between parties in which one party agrees to make periodic payments to the other party based on a pre-determined underlying investment or notional amount. In return, the other party agrees to make periodic payments to the first party based on the return (or differential in rates of return) earned or realized on the underlying investment or notional amount. 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 swap agreements, including commodity swaps, currency swaps, interest rate swaps, securities swaps and index swaps. The use of such 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 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.

An investment in the 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.

Set forth below is more detailed information regarding the types of instruments in which the Fund may invest, strategies BFA may employ in pursuit of the Fund's investment objective and related risks.

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 cause the Fund to incur 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.

Commodities Investment Risk. Exposure to commodities markets may subject the Fund to greater volatility than investments in traditional securities. The commodities markets have experienced periods of extreme volatility. Similar future market conditions may result in rapid and substantial valuation increases or decreases in the Fund’s holdings.

The commodities markets may fluctuate widely based on a variety of factors. Movements in commodity investment prices are outside of the Fund's control and may not be anticipated by BFA. Price movements may be influenced by, among other things: governmental, agricultural, trade, fiscal, monetary and exchange control programs and policies; changing market and economic conditions; market liquidity; weather and climate conditions, including droughts and floods; livestock disease; changing supply and demand relationships and levels of domestic production and imported commodities; changes in

storage costs; the availability of local, intrastate and interstate transportation systems; energy conservation; the success of exploration projects; changes in international balances of payments and trade; domestic and foreign rates of inflation; currency devaluations and revaluations; domestic and foreign political and economic events; domestic and foreign interest rates and/or investor expectations concerning interest rates; foreign currency/exchange rates; domestic and foreign governmental regulation and taxation; war, acts of terrorism and other political upheaval and conflicts; governmental expropriation; investment and trading activities of mutual funds, hedge funds and commodities funds; and changes in philosophies and emotions of market participants. The frequency and magnitude of such changes cannot be predicted. However, it is likely that current declines in trade relations between the U.S. and other countries and tariffs imposed by the U.S. on foreign products and by foreign countries on U.S. commodities will impact commodity prices.

The prices of commodities can also fluctuate widely due to supply and demand disruptions in major producing or consuming regions. Certain commodities or natural resources may be produced in a limited number of countries and may be controlled by a small number of producers or groups of producers. As a result, political, economic, regulatory and supply-related events in such countries could have a disproportionate impact on the prices of such commodities.

A decrease in the production of a physical commodity or a decrease in the volume of such commodity available for transportation, mining, processing, storage or distribution may adversely impact the financial performance of a commodity or commodity-related company that devotes a portion of its business to that commodity. Production declines and volume decreases could be caused by various factors, including catastrophic events affecting production, depletion of resources, labor difficulties, environmental proceedings, increased regulations, equipment failures and unexpected maintenance problems, import supply disruption, governmental expropriation, political upheaval or conflicts or increased competition from alternative energy sources or commodity prices. Agricultural commodities may be adversely affected by weather or other natural phenomena, such as drought, floods and pests.

A sustained decline in demand for such commodities could also adversely affect the financial performance of commodity-related companies. Factors that could lead to a decline in demand include economic recession or other adverse economic conditions, higher taxes on commodities or increased governmental regulations, increases in fuel economy, consumer shifts to the use of alternative commodities or fuel sources, changes in commodity prices, or weather.

The commodity markets are subject to temporary distortions and other disruptions due to, among other factors, lack of liquidity, the participation of speculators, and government regulation and other actions. U.S. futures exchanges and some foreign exchanges limit the amount of fluctuation in futures contract prices which may occur in a single business day (generally referred to as “daily price fluctuation limits”). The maximum or minimum price of a contract as a result of these limits is referred to as a “limit price.” If the limit price has been reached in a particular contract, no trades may be made beyond the limit price. Limit prices have the effect of precluding trading in a particular contract or forcing the liquidation of contracts at disadvantageous times or prices.

Commodity Forward Risk. A commodity forward is a customized, non-standardized agreement that obligates one party to buy, and the other party to sell, a specific quantity of an underlying commodity for an agreed-upon price at a future date, usually for physical delivery. Commodity forwards that are settled by a cash payment at maturity are referred to as a “non-deliverable forward” or NDF. Because commodity forwards do not trade on a centralized exchange, they are subject to a higher degree of default risk and, depending upon the underlying commodity, may be less liquid than futures contracts on the same referenced commodity. In addition, use of commodity forwards creates risk for the Fund because the contracts require the Fund to take or make delivery of a physical commodity, which involves additional cost as well as delivery risk. Unless the Fund were to close out a contract prior to maturity, any failure of the Fund to comply with the contract delivery obligations at maturity would cause the Fund to default, which could have adverse collateral consequences for investors.

Commodity-Linked Derivatives Risk. The value of a commodity-linked derivative instrument typically is based upon the price movements of a commodity or an economic variable linked to such price movements. Therefore, the value of commodity-linked derivative instruments may be affected by changes in overall economic conditions, in interest rates, or factors affecting a particular commodity or industry, such as production, disease, climate conditions, supply or demand, politics, geopolitics, changes in international balance of payments and trade, currency devaluations and revaluations, market liquidity, and economic and regulatory developments. The prices of commodity-related investments may fluctuate quickly and dramatically and may or may not correlate to price movements in other asset classes, such as stocks, bonds and cash. A highly liquid secondary market may not exist for certain commodity-linked derivatives, and there can be no assurance that one will develop. Commodity derivatives are subject to the risk that the counterparty to the transaction may default or

otherwise fail to perform. The Fund’s use of commodity-linked derivatives can result in large amounts of financial leverage. Although the Fund will not borrow money in order to increase the amount of its trading, the low margin deposits normally required in futures trading permit a high degree of leverage on the investment itself. Accordingly, a relatively small price movement in a futures contract may result in immediate and substantial losses to the Fund. Like other leveraged investments, any trade may result in losses in excess of the amount invested. These factors and events could have a significant negative impact on the Fund.

Liquidity Risk Management Rule Risk. In October 2016, the SEC adopted the Liquidity Rule requiring open-end funds, including ETFs such as the Fund, to establish a liquidity risk management program and enhance disclosures regarding fund liquidity. Effective December 1, 2018, as required by the Liquidity Rule, the Fund has implemented the initial portions of the Fund's Liquidity Program, and the Board, including a majority of the Independent Trustees of the Fund has appointed BFA as the liquidity risk program administrator of the Liquidity Program. Under the Liquidity Program, BFA, assesses, manages, and periodically reviews the Fund’s liquidity risk. Certain aspects of the Liquidity Program have been implemented effective December 1, 2018, while the entire Program will take effect on June 1, 2019. There are exclusions from certain portions of the liquidity risk management program requirements for “in-kind” ETFs, as defined in the Liquidity Rule.

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 commodity 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.

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. 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, 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 bond 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 loss by the Fund 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 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).

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.

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.

Valuation Risk. In certain circumstances, the Fund’s securities may be valued using techniques other than market quotations. The value established for a security may be different from what would be produced through the use of another methodology or if the value had been priced using market quotations. Securities that are valued using methods other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their value from one day to the next than would be the case if market quotations were used. In addition, there is no assurance that the Fund could sell a security for the value established for it at any time, and it is possible that the Fund could incur a loss if a security is sold for less than its established value.

U.S. Treasury Obligations Risk. The Fund invests in various types of U.S. Treasury securities. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of U.S. Treasury obligations to decline. U.S. Treasury obligations typically offer lower interest rates than other obligations. Neither the U.S. government nor any of its agencies or instrumentalities guarantees the market value of the securities it issues.

The total public debt of the U.S. as a percent of gross domestic product has grown rapidly since the beginning of the recent financial downturn. Although high debt levels do not necessarily indicate or cause economic problems, they may create systemic risks if sound debt management practices are not implemented. A high national debt level may increase market pressures to meet government funding needs, which may drive debt cost higher and cause a country to sell additional debt, thereby increasing refinancing risk. A high national debt also raises concerns that a government will not be able to make principal or interest payments when they are due. In the worst case, unsustainable debt levels can cause a decline in the value of the dollar (which may lead to inflation), and can prevent the U.S. government from implementing effective counter-cyclical fiscal policy in economic downturns.

On August 5, 2011, S&P Global Ratings downgraded U.S. Treasury securities from an AAA rating to AA+. A further downgrade of the ratings of U.S. government debt obligations, which are often used as a benchmark for other borrowing arrangements, could result in higher interest rates for individual and corporate borrowers, cause disruptions in the international bond markets and generally have a substantial negative effect on the U.S. economy. A downgrade of U.S. Treasury securities from another ratings agency or a further downgrade beyond AA+ rating by S&P Global Ratings may cause the value of the Fund's U.S. Treasury obligations to decline.

Risk of Investing in the Energy Sector. The energy sector is 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. 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 the Fund invests. The value of securities in the energy sector may be adversely affected by terrorism, natural disasters or other catastrophes. 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 much of the energy sector may operate, has historically and recently experienced widespread social unrest. 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.

Proxy Voting Policy

For the Fund, the Board has delegated the voting of proxies for the Fund’s securities to BFA pursuant to the Fund's Proxy Voting Policy (the “iShares ETFs Proxy Voting Policy”), and BlackRock, Inc. has adopted policies and procedures (the “BlackRock Proxy Voting Policies”) governing proxy voting by accounts managed by BlackRock, Inc., including the Fund.

Under the BlackRock Proxy Voting Policies, 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 iShares ETFs Proxy Voting Policy and the BlackRock Proxy Voting Policies are attached as Appendices A1 and A2, respectively.

Information with respect to how proxies relating to the Fund's portfolio securities were voted during the 12-month period ended 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 portfolio holdings and certain other information each day the Fund is open for business 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, exemptive orders granted to the Trust by the SEC, and federal securities laws and regulations thereunder. 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.

Investment Policies

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 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.
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 (“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.
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 Policies

The following notations are not considered to be part of the Fund’s fundamental investment policies 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. Additionally, the policy will be interpreted to not classify commodity as an 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 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.

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.

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 policy such that, under normal market conditions, any borrowings by the Fund will not exceed 10% of the Fund’s net assets.

The Fund has adopted a non-fundamental policy not to 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).

Unless otherwise indicated, all limitations under the Fund's fundamental or non-fundamental investment policies 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.

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.

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 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.

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.

As of December 31, 2017, none of the Independent Trustees or their immediate family members owned beneficially or of record any securities of BFA (the Fund's investment adviser), the Distributor or any person controlling, controlled by or under common control with BFA or the Distributor.

Remuneration of Trustees and Advisory Board Members. Effective January 1, 2017, each current Independent Trustee is paid an annual retainer of $325,000 for his or her services as a Board member to the BlackRock-advised Funds in the Exchange-Traded Fund Complex, together with out-of-pocket expenses in accordance with the Board’s policy on travel and other business expenses relating to attendance at meetings. The annual retainer for services as an Advisory Board Member is the same as the annual retainer for services as a Board member. The Independent Chair of the Board is paid an additional annual retainer of $80,000 (prior to January 1, 2018, the additional annual retainer was $50,000). The Chair of each of the Equity Plus Committee, Fixed Income Plus Committee, Securities Lending Committee, Risk Committee, Nominating and Governance Committee and 15(c) Committee is paid an additional annual retainer of $25,000.

Control Persons and Principal Holders of Securities. Ownership information is not provided for the Fund, as it has not commenced operations as of the date of this SAI.

Potential Conflicts of Interest. The PNC Financial Services Group, Inc. (“PNC”), through a subsidiary, has a significant economic interest in BlackRock, Inc., the parent of BFA, the Fund's investment adviser. Certain activities of BFA, BlackRock, Inc. and the other subsidiaries of BlackRock, Inc. (collectively referred to in this section as “BlackRock”) and PNC and its subsidiaries (collectively referred to in this section as the “Entities”), and their respective directors, officers and employees, with respect to the Fund and/or other accounts managed by BlackRock or Entities, 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 subsidiaries and each of their respective directors, officers and employees, including, in the case of BlackRock, the business units or 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 Entities 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. BlackRock and Entities are also major participants in the global currency, equities, swap and fixed income markets, in each case, for the accounts of clients and, in some cases, on a proprietary basis. As such, BlackRock and Entities 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 seeks to purchase or sell the same assets for managed accounts, including the Fund, the assets actually purchased or sold may be allocated among the accounts on a basis determined in its 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 Entities 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 with respect to BlackRock-advised accounts 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 implements 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 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. 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) BlackRock or its 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) BlackRock or its other accounts or funds. In addition, to the extent permitted by applicable law, the Fund may invest its assets in other funds advised by BlackRock, including funds that are managed by one or more of the same portfolio managers, which could result in conflicts of interest relating to asset allocation, timing of Fund purchases and redemptions, and increased remuneration and profitability for BlackRock, and/or its personnel, including portfolio managers.

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. BlackRock may (but is not required to) effect purchases and sales between BlackRock clients (“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 Entities and their respective 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 Entities or their respective 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 for its proprietary accounts or other accounts (including investment companies or collective investment vehicles) which it manages or advises. It is possible that one or more accounts managed or advised by BlackRock 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 proprietary or other accounts managed or advised by BlackRock achieve significant profits. 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 Entities or other accounts managed or advised by BlackRock or an Entity for clients worldwide, and/or the internal policies of BlackRock and the Entities designed to comply with such requirements. As a result, there may be periods, for example, when BlackRock will not initiate or recommend certain types of transactions in certain securities or instruments with respect to which BlackRock and/or one or more Entities are performing services or when position limits have been reached. For example, the investment activities of BlackRock or one or more Entities 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.

In connection with its management of the Fund, BlackRock may have access to certain fundamental analysis and proprietary technical models developed by BlackRock. 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, BlackRock will not 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, or the activities or strategies used for accounts managed by BlackRock or other client 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 for use by clients and financial advisors. To the extent clients invest in these investment models and increase the assets under management of the Fund, the investment management fee amounts paid by the Fund to BlackRock may also increase. 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 the Fund’s investment adviser are also principals or employees of other business units or entities within BlackRock. As a result, these principals and employees may have obligations to such other business units or entities or their clients and such obligations to other business units or entities or their 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 an Entity, or, to the extent permitted by the SEC and applicable law, BlackRock or an Entity, 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 an Entity.

BlackRock or one or more Entities may also create, write or issue derivatives for their clients, the underlying securities, currencies or instruments in which the Fund may invest or which may be based on the performance of the Fund. BlackRock has entered into an arrangement with Markit Indices Limited, the index provider for certain underlying fixed-income indexes used by iShares funds, related to derivative fixed-income products that are based on such iShares funds. If such products are launched, BlackRock will receive certain payments in connection with their development, for licensing intellectual property belonging to BlackRock and for facilitating data in connection with such fixed-income derivative products, which may include payments based on the trading volumes of, or revenues generated by, the derivative products. Other accounts managed by BlackRock may from time to time transact in such fixed-income derivative products. Trading activity in the derivative products could potentially lead to increased purchase activity with respect to the iShares funds and increased assets under management for BlackRock.

The Fund may, subject to applicable law, purchase investments that are the subject of an underwriting or other distribution by BlackRock or one or more Entities and may also enter into transactions with other clients of BlackRock or an Entity where such other clients have interests adverse to those of the Fund.

At times, these activities may cause business units or entities within BlackRock or an Entity to give advice to clients that may cause these clients to take actions adverse to the interests of the Fund. To the extent such transactions are permitted, the Fund will deal with BlackRock and/or Entities on an arm’s-length basis.

To the extent authorized by applicable law, BlackRock or one or more Entities may act as broker, dealer, agent, lender or adviser, futures commission merchants or in other commercial capacities for the Fund. It is anticipated that the commissions, mark-ups, mark-downs, 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 BlackRock or an Entity will be in its view commercially reasonable, although BlackRock and each Entity, including its sales personnel, will have an interest in obtaining fees and other amounts that are favorable to BlackRock or the Entity and such sales personnel, which may have an adverse effect on the Fund. Index based funds also may use an index provider that is affiliated with another service provider of the Fund or BlackRock that acts as a broker, dealer, agent, lender or in other commercial capacities for the Fund or BlackRock.

Subject to applicable law, BlackRock and the Entities (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, futures commission merchants 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 BlackRock or an Entity of any such fees or other amounts.

When BlackRock or an Entity acts as broker, dealer, agent, adviser, futures commission merchants or in other commercial capacities in relation to the Fund, BlackRock or the Entity 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. BlackRock will not have any obligation to allow its 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 in evaluating the Fund's creditworthiness.

BTC, an affiliate of BFA pursuant to SEC exemptive relief, acts as securities lending agent to, and receives a share of securities lending revenues from, the Fund. BlackRock 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) BlackRock 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 BlackRock and its affiliates; and (ii) BlackRock 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 and/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 accounts, including with accounts that pay different transaction costs solely 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 are made separately, or if they determine that bunching or aggregating is not practicable or required, 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.

Subject to applicable law, BlackRock may select brokers (including, without limitation, certain Entities) that furnish BlackRock, the Fund, other BlackRock client accounts 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 any or all of the Fund and 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, unless prohibited by applicable law, 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, unless prohibited by applicable law, may also enter into commission sharing arrangements under which BlackRock may execute transactions through a broker-dealer, including, where permitted, an Entity, 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 an Entity has 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 an Entity, 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 an Entity 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 Entities 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 an Entity 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 Entity has developed or is trying to develop investment banking relationships as well as securities of entities in which BlackRock or an Entity has significant debt or equity investments or other interests or in which an Entity makes a market. The Fund may also invest in issuances (such as structured notes) by entities for which BlackRock provides and is compensated for cash management services relating to the proceeds from the sale of such issuances. The Fund also may invest in securities of, or engage in transactions with, companies to which an Entity 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 an Entity. In making investment decisions for the Fund, BlackRock is not permitted to obtain or use material non-public information acquired by any unit of BlackRock in the course of these activities. In addition, from time to time, the activities of BlackRock or an Entity may limit the Fund's flexibility in purchases and sales of securities. When an Entity 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 an Entity may engage in transactions with companies in which BlackRock-advised funds or other clients of BlackRock or of an Entity 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 Entities, their personnel and other financial service providers may have interests in promoting sales of the Fund. With respect to BlackRock and the Entities 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 Entities 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 Entities 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.

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 may provide valuation assistance to certain clients with respect to certain securities or other investments and the valuation recommendations made for such 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 reasonably 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 its 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 and employees 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 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.

BlackRock 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 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 BlackRock or an Entity is performing investment banking, market making, advisory or other services or has proprietary positions. For example, when BlackRock is engaged to provide 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 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 Entity, or are the subject of an advisory or risk management assignment by BlackRock, or where personnel of BlackRock are directors or officers of the issuer.

The investment activities of BlackRock 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 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.

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 its 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 may not serve as an Authorized Participant in the creation and redemption of iShares ETFs.

BlackRock may maintain securities indices. To the extent permitted by applicable laws, the Fund may seek to license and use such indices as part of its investment strategy. Index based funds that seek to track the performance of securities indices also may use the name of the index or index provider in the fund name. Index providers, including BlackRock (to the extent permitted by applicable law), may be paid licensing fees for use of their index or index name. BlackRock may benefit from the Fund using BlackRock indices by creating increasing acceptance in the marketplace for such indices. BlackRock is not obligated to license its indices to any Fund and the Fund is under no obligation to use BlackRock indices. Any Fund that enters into a license for a BlackRock index cannot be assured that the terms of any index licensing agreement with BlackRock will be as favorable as those terms offered to other licensees.

The custody arrangement described in “Investment Advisory, Administrative and Distribution Services” may lead to potential conflicts of interest with BlackRock where BlackRock has agreed to waive fees and/or reimburse ordinary operating expenses in order to cap expenses of the Fund (or where BlackRock charges a unitary management fee). This is because the custody arrangements with the Fund's custodian may have the effect of reducing custody fees when the Fund leaves cash balances uninvested. This could be viewed as having the potential to provide BlackRock an incentive to keep high positive cash balances for the Fund in order to offset fund custody fees that BlackRock might otherwise reimburse or pay. However, BlackRock’s portfolio managers do not intentionally keep uninvested balances high, but rather make investment decisions that they anticipate will be beneficial to fund performance. For funds without a unitary management fee, when a fund’s actual operating expense ratio exceeds a stated cap, a reduction in custody fees reduces the amount of waivers and/or reimbursements BlackRock would be required to make to the fund.

BlackRock may enter into contractual arrangements with third-party service providers to the Fund (e.g., custodians, administrators and index providers) 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 owns or has 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 for the use of the systems. The Fund service provider’s payments to BlackRock for the use of these systems may enhance the profitability of BlackRock.

BlackRock has entered into an arrangement with Intercontinental Exchange, Inc. (“ICE”) to be one of ICE’s development partners in connection with ICE’s intention to launch a new open-architecture, centralized industry platform to facilitate creation and redemption orders for ETFs (the “ICE Platform”). As a development partner, BlackRock has licensed certain of its intellectual property to ICE. Once the ICE Platform is launched, BlackRock intends to use the ICE Platform to facilitate creations and redemptions in the Fund and certain other services provided by the ICE Platform. BlackRock may have an incentive to promote the broad adoption of the ICE Platform by the ETF marketplace because BlackRock will earn a fee, based on the total revenues earned by the ICE Platform, for licensing BlackRock’s intellectual property to ICE and for BlackRock’s role as development partner. ICE Data Services, the underlying index provider for certain of the Funds, is a wholly owned subsidiary of ICE.

BlackRock’s receipt of fees from a service provider in connection with the use of systems provided by BlackRock may create an incentive for BlackRock to recommend that the Fund enter into or renew an arrangement with the service provider.

The Fund from time to time may purchase in the secondary market (i) certain mortgage pass-through securities packaged and master serviced by PNC Mortgage Securities Corp. (“PNC Mortgage”) or Midland Loan Services, Inc. (“Midland”), or (ii) mortgage-related securities containing loans or mortgages originated by PNC Bank, National Association (“PNC Bank”) or its affiliates. It is possible that under some circumstances, PNC Mortgage, Midland or other affiliates could have interests that are in conflict with the holders of these mortgage-backed securities, and such holders could have rights against PNC Mortgage, Midland or their affiliates. For example, if PNC Mortgage, Midland or their affiliates engaged in negligence or willful misconduct in carrying out its duties as a master servicer, then any holder of the mortgage-backed security could seek recourse against PNC Mortgage, Midland or their affiliates, as applicable. Also, as a master servicer, PNC Mortgage, Midland or their affiliates may make certain representations and warranties regarding the quality of the mortgages and properties

underlying a mortgage-backed security. If one or more of those representations or warranties is false, then the holders of the mortgage backed securities could trigger an obligation of PNC Mortgage, Midland or their affiliates, as applicable, to repurchase the mortgages from the issuing trust. Finally, PNC Mortgage, Midland or their affiliates may own securities that are subordinate to the senior mortgage-backed securities owned by the Fund.

Present and future activities of BlackRock (including BFA) and the Entities and their respective directors, officers and employees, 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 iShares Trust, BlackRock, Inc. and certain of its advisory affiliates, and certain directors/trustees and officers of iShares 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 making investment decisions for 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 expense, taxes, expenses incurred with respect to the acquisition and disposition of portfolio securities, commodities or other financial instruments 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). For the avoidance of doubt, extraordinary expenses do not include expenses related to the organization of any subsidiary for the Fund or the ongoing corporate expenses of maintaining such subsidiary.

For its investment advisory services to the Fund, BFA will be paid a management fee by the Fund, based on a percentage of the Fund's average daily net assets, at an annual rate of __%. BFA also serves as investment adviser to the Subsidiary. No fee will be paid to BFA for the advisory services that it provides to the Subsidiary.

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 ______, 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:

Alan Mason
Types of Accounts	Number	Total Assets
Registered Investment Companies	____	$____
Other Pooled Investment Vehicles	____	____
Other Accounts	____	____

Richard Mejzak

Pursuant to BFA’s policies, 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 _____, 2018:

The discussion below describes the Portfolio Managers' compensation as of ___________, 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.

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 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. Alan Mason and Richard Mejzak are each eligible to participate in these plans.

As of ___________, 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.

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), Depository Trust Company (“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. The Fund may engage in 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”).

If the Fund were to engage in securities lending, it would retain a portion of the securities lending income and remit 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. To the extent that the Fund engages in 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 retain 71.5% of securities lending income (which excludes collateral investment fees) and this amount can never be less than 65% of the sum of securities lending income plus collateral investment fees;

(ii) international equity funds retain 80% of securities lending income (which excludes collateral investment fees) and this amount can never be less than 70% of the sum of securities lending income plus collateral investment fees;

(iii) fixed-income funds retain 80% of securities lending income (which excludes collateral investment fees) and this amount can never be less than 70% of the sum of securities lending income plus collateral investment fees; and

(iv) fund-of-funds retain 80% of securities lending income (which excludes collateral investment fees) and this amount can never be less than 70% of the sum of securities lending income plus collateral investment fees.

Under the securities lending program, 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) pursuant to the securities lending agreement:

(i) each applicable domestic equity fund will receive 75% of securities lending income (which excludes collateral investment fees) for the remainder of that calendar year and this amount can never be less than 65% of the sum of securities lending income plus collateral investment fees;

(ii) each applicable international equity fund will receive 85% of securities lending income (which excludes collateral investment fees) for the remainder of that calendar year and this amount can never be less than 70% of the sum of securities lending income plus collateral investment fees;

(iii) each applicable fixed-income fund will receive 85% of securities lending income (which excludes collateral investment fees) for the remainder of that calendar year and this amount can never be less than 70% of the sum of securities lending income plus collateral investment fees; and

(iv) each applicable fund-of-funds will receive 85% of securities lending income (which excludes collateral investment fees) for the remainder of that calendar year and this amount can never be less than 70% of the sum of securities lending income plus collateral investment fees.

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 ________________.

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.

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

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. 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 or other assets 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.

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.

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) 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.

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.

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).

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.

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.

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.

Additional Information Concerning the Trust

Shares. The Trust currently consists of __ 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, 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 U.S. ETF 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, or 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 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”).

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.

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.

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 _________, 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 is generally cash. However, in some cases the consideration 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 will be applicable (subject to possible amendment or correction) to creation requests received in proper form. 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.

The Fund’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 other instruments) 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. 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 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 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 Fund's portfolio.

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. As noted above, Creation Units currently are available only for cash purchases.

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 (Creation Units of the Fund are generally offered solely 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.

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.

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. 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 the Trust, be unlawful; (vi) acceptance of the Fund Deposit would, in the discretion of the Fund or the Distributor, 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). 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 the Regular Holidays section 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 122%, 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.

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.

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*

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 solely for cash. However, the Fund reserves the right to distribute securities and other 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 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 and other instruments (including any portion of such securities and other instruments 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 other instruments 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. Procedures and requirements governing redemption transactions are set forth in the handbook for Authorized Participants and may change from time to time.

If redemptions are not paid in cash, the redemption proceeds for a Creation Unit generally consist of Fund Securities and other instruments, 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 and other instruments, 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 or other instrument. 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 or other instrument to the Authorized Participant would be restricted under applicable securities or other local laws; or (ii) the delivery of a Fund Security or other instrument to the Authorized

Participant would result in the disposition of the Fund Security or other instrument 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 cash.

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 (Creation Units of the Fund are generally redeemed solely 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 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 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*
$__		__%

*	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.

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.

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”). 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 to accommodate non-U.S. market holiday schedules (as discussed in the Regular Holidays section 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. The Regular Holidays section 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 the Regular Holidays section of this SAI but up to a maximum of 14 days.

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 122%, 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 and 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.

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.

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 will be extended by the number of such intervening holidays up to a maximum of 14 days. 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 14 days. 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 at some point 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):

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.

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.

The Subsidiary will not be subject to U.S. federal income tax. The Subsidiary will, however, be considered a controlled foreign corporation, and the Fund will be required to include as income annually amounts earned by the Subsidiary during that year. The Fund will be subject to the distribution requirements described above on such Subsidiary income, whether or not the Subsidiary makes a distribution to the Fund during the taxable year. The Fund expects its income with respect to the Subsidiary to be qualifying income. There is a risk that the IRS could issue regulations or other guidance holding, or could assert, that the Fund’s income with respect to the Subsidiary will not be considered “qualifying income” for purposes of the Fund remaining qualified as a RIC for U.S. federal income tax purposes. In such circumstances, the Fund may be required to make changes to its operations, which may reduce the Fund’s ability to gain investment exposure to commodities. Fund shareholders may also experience adverse tax consequences in such circumstances.

In addition, the Fund’s income from the Subsidiary will be treated as ordinary income. If the Fund were able to invest directly in commodity-linked derivatives, its gains and losses would generally be treated as 60% long-term and 40% short-term gain or loss, to the extent such derivatives are subject to the rules for Section 1256 futures contracts. See “Taxation of Certain Derivatives” below.

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, if any, may be subject to limitation.

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. 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.

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.

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)). 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.

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 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 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. Shareholders that are nonresident aliens or foreign entities are urged to consult their own tax advisors concerning the particular tax consequences to them of an investment in a 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 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.

Procedures Governing Delegation of Proxy Voting to Fund Adviser

December 29, 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 (or may refrain from voting) in accordance with the BlackRock Proxy Voting Guidelines.

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 representation that all votes were in accordance with the BlackRock Proxy Voting Guidelines¹, and (2) any changes to the BlackRock Proxy Voting Guidelines that have not previously been reported.

INTRODUCTION TO BLACKROCK

BlackRock is one of the world’s leading asset management firms. We manage assets on behalf of institutional and individual clients worldwide, across equity, fixed income, liquidity, real estate, alternatives, and multi-asset strategies. Our client base includes pension plans, endowments, foundations, charities, official institutions, insurers and other financial institutions, as well as individuals around the world.

PHILOSOPHY ON CORPORATE GOVERNANCE

BlackRock’s Investment Stewardship 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 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 is set out in the section below titled “BlackRock’s oversight of its investment stewardship 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 investment stewardship 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 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:

A-4

•	Boards and directors;
•	Auditors and audit-related issues;
•	Capital structure, mergers, asset sales and other special transactions;
•	Remuneration and benefits;
•	Environmental and social issues; and
•	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 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 environmental and social 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 committees of the board and 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;
•	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;

A-5

•	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 or, where the chairman is also the CEO or is otherwise not independent, 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 board forms committees of fully independent directors to deal with such matters. In many markets, these 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-emptive 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 executives’ and/or board members’ financial interests in a given transaction have not adversely 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 non-conflicted shareholders to vote separately on the proposal.

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.

A-6

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 foster the sustainable achievement of results. The vesting timeframes associated with incentive plans should facilitate a focus on long-term value creation. We believe consideration should be given to building clawback 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.

Non-executive 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.

Environmental and social 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 investment stewardship activities. We believe that well-managed companies will deal effectively with the environmental and social (“E&S”) aspects of their businesses.

BlackRock expects companies to identify and report on the material, business-specific E&S 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 E&S 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 E&S 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 E&S 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 E&S 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 E&S matters are often not voting issues, we will engage directly with the board or management. The trigger for engagement on a particular E&S 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 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.

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 Investment Stewardship believes shareholders should have the right to vote on key

A-7

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 INVESTMENT STEWARDSHIP ACTIVITIES

Oversight

BlackRock holds itself to a very high standard in its investment stewardship activities, including in relation to executing proxy votes. This function is executed by a team of dedicated BlackRock employees without sales responsibilities (“Investment Stewardship Group”), and which is considered an investment function. BlackRock maintains three regional advisory committees (“Stewardship Advisory Committees”) for (a) the Americas; (b) Europe, the Middle East and Africa (“EMEA”); and (c) Asia-Pacific, generally consisting of senior BlackRock investment professionals and/or senior employees with practical boardroom experience. The regional Stewardship Advisory Committees review and advise on amendments to the proxy voting guidelines covering markets within each respective region (“Guidelines”). The Investment Stewardship Global Oversight Committee (“Global Committee”), which is a risk-focused committee, is generally composed of senior representatives of the active and index equity investment businesses, the Deputy General Counsel, the senior executive to whom the Investment Stewardship Group reports, the Global Head of Investment Stewardship (“Global Head”), and other senior representatives of relevant functions, as appropriate. The Global Head, a dedicated BlackRock employee without sales responsibilities, has primary oversight of the activities of the Investment Stewardship Group, including voting in accordance with the Guidelines, which requires the application of professional judgment and consideration of each company’s unique circumstances. The Global Committee reviews and approves amendments to these Global Corporate Governance & Engagement Principles. The Global Committee also reviews and approves amendments to the Guidelines, as proposed by the regional Stewardship Advisory Committees. The Global Committee also receives and reviews periodic reports regarding the votes cast by the Investment Stewardship Group and regular updates on material process issues, procedural changes and other matters of concern to the Global Committee. The Global Committee reviews these reports in an oversight capacity and as informed by BlackRock’s corporate governance engagement program and Guidelines, which set forth each Stewardship Advisory Committees’ views with respect to certain corporate governance and other issues that typically arise in the proxy voting context. In addition, the Investment Stewardship Group carries out engagement with companies (including in conjunction with portfolio managers in discussions of significant governance issues), monitors and executes proxy votes, and conducts vote operations (including maintaining records of votes cast) in a manner consistent with the relevant Guidelines. The Investment Stewardship Group also conducts research on corporate governance issues and participates in industry discussions to keep abreast of important developments in the corporate governance field. The Investment Stewardship Group may utilize vendors for certain of the foregoing activities and performs oversight of those vendors. The Investment Stewardship Group may raise complicated or particularly controversial matters for internal discussion with the appropriate investors (generally, those with relevant knowledge or experience) and/or refer such matters to the appropriate regional Stewardship Advisory Committees for their review, discussion and guidance prior to making a voting decision. BlackRock’s Equity Policy Oversight Committee is informed of certain aspects of the work of the Global Committee and the Investment Stewardship 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 shareholder proponent or dissident shareholder) to the Fund, the Fund’s affiliates (if any), BlackRock or BlackRock’s affiliates, or BlackRock employees (see “Conflicts management policies and procedures”, below).

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 Stewardship Advisory Committees. The Investment Stewardship Group may, in the exercise of their professional judgment, conclude that the Guidelines do not cover the specific matter upon which a proxy vote is required or that an exception to the Guidelines would be in the best long-term economic interests of BlackRock’s clients.

A-8

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 Investment Stewardship 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 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; (vi) regulatory constraints; and (vii) 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 only on a “best-efforts” basis. In addition, the Investment Stewardship Group may determine that it is generally in the best interests of BlackRock’s clients not to vote proxies if 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 Investment Stewardship Group, 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 objectives or other factors that differentiate it from other accounts. In addition, portfolio managers may from time to time reach differing but equally valid views 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 policies and procedures

The Investment Stewardship Group maintains the following policies and procedures that seek to prevent undue influence on BlackRock’s proxy voting activity. Such influence might stem from any relationship between the issuer of a proxy (or any shareholder proponent or dissident shareholder) and BlackRock, BlackRock’s affiliates, a Fund or a Fund’s affiliates, or BlackRock employees. The following are examples of sources of perceived or potential conflicts of interest:

•	BlackRock clients who may be issuers of securities or proponents of shareholder resolutions
•	BlackRock business partners or vendors who may be issuers of securities or proponents of shareholder resolutions
•	BlackRock employees who may sit on the boards of public companies held in BlackRock portfolios
•	Significant BlackRock, Inc. investors who may be issuers of securities held in BlackRock portfolios
•	Securities of BlackRock, Inc. or BlackRock investment funds held in BlackRock portfolios
•	BlackRock, Inc. board members who actively serve as senior executives of public companies held in BlackRock portfolios

BlackRock has taken certain steps to mitigate perceived or potential conflicts including, but not limited to, the following:

•

Adopted the Guidelines which are designed to protect and enhance the economic value of the companies in which BlackRock invests on behalf of clients.

•

Established a reporting structure that separates the Global Head and Investment Stewardship Group from employees with sales, vendor management or business partnership roles. In addition, BlackRock seeks to ensure that all engagements with corporate issuers, dissident shareholders or shareholder proponents are managed consistently and without regard to BlackRock’s relationship with such parties. Clients or business partners are not given special treatment or differentiated access to the Investment Stewardship Group, which seeks to treat equally all issuers and other market participants wishing to engage with BlackRock on corporate governance matters. The Investment Stewardship Group prioritizes based on factors including but not limited to its need for additional information to make a voting decision or its view on the likelihood that an engagement could lead to positive outcomes over time for the economic value of securities held in client portfolios. Within the normal course of business, the Global Head or Investment Stewardship Group may engage directly with BlackRock clients, business partners and/or vendors, and/or with employees with sales, vendor management or business partnership roles, in discussions regarding general corporate governance policy matters, and/or to otherwise ensure that proxy-related client service levels are met.

Determined to engage, in certain instances, an independent fiduciary to vote proxies as a further safeguard to avoid potential conflicts of interest, to satisfy regulatory compliance requirements, or as may be otherwise required by applicable law. In such circumstances, the independent fiduciary provides BlackRock’s proxy voting agent with instructions, in accordance with the Guidelines, as to how to vote such proxies, and BlackRock’s proxy voting agent votes the proxy in accordance with the independent fiduciary’s determination. BlackRock uses an independent fiduciary to vote proxies of (i) any company that is affiliated with BlackRock, Inc., (ii) any public company that includes BlackRock employees on its board of directors, (iii) The PNC Financial Services Group, Inc., (iv) any public company of which a BlackRock, Inc. board member serves as a senior executive, and (v) companies when legal or regulatory requirements compel BlackRock to use an independent fiduciary. In selecting an independent fiduciary, we assess several characteristics, including but not limited to: independence, an ability to analyze proxy issues and vote in the best economic interest of our clients, reputation for reliability and integrity, and operational capacity to accurately deliver the assigned votes in a timely manner. We may engage more than one independent fiduciary, in part in order to mitigate potential or perceived conflicts of interest at an independent fiduciary. The Global Committee appoints and reviews the performance of the independent fiduciar(ies), generally on an annual basis.

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 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. The Investment Stewardship Group 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 the Investment Stewardship Group will vote in every instance. Rather, they share our view about corporate governance issues generally, and provide insight into how BlackRock typically approaches 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 on the BlackRock website more detailed reports of our stewardship activities, including engagement with companies and with other relevant parties.

A-10

The Trust (also referred to in this section as the “Fund”) is organized as a Delaware statutory trust and is operated pursuant to an 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 every person who is, or has been, a trustee or officer of the Trust (a “Covered Person”) shall be indemnified by the Trust or the applicable Fund 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.

(i) who shall have been adjudicated by a court or body before which the proceeding was brought (A) to be liable to the Trust or its shareholders by reason of willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of his office or (B) not to have acted in good faith in the reasonable belief that his action was in the best interest of the Trust; or

(ii) in the event of a settlement, unless there has been a determination that such trustee or officer did not engage in willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of his office: (A) by the court or other body approving the settlement; (B) by at least a majority of those trustees who neither are “interested persons” (as defined in the 1940 Act) of the Trust nor are parties to the matter based upon a review of readily-available facts (as opposed to a full trial-type inquiry); or (C) by written opinion of independent legal counsel based upon a review of readily-available facts (as opposed to a full trial-type inquiry).

The 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 of the Master Services Agreement between Registrant and State Street:

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.

The Master Services Agreement also provides that applicable Fund will indemnify, defend and hold harmless State Street, its Affiliates and their respective officers, directors, employees, agents and permitted successors and assigns from any and all Losses arising from or in connection with any third party claim based 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 such Fund of any of its confidentiality obligations hereunder or under a Service Module to which such Fund is a signatory; (b) any claim or action by, on behalf of, or related to, any prospective, then-current or former employees of such Fund arising from or in connection with a Service Module to which such 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 such Fund; (iii) any claim relating to any violation by such Fund, or its 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 State Street is an employer or joint employer of any such prospective, then current or former employee of such Fund.

Each Party will indemnify, defend and hold harmless the other Party and their respective officers, directors, employees, agents, successors and assigns from any and all Losses arising from or in connection with any of the following, including Losses arising from or in connection with any third party claim or threatened third party claim: (a) the death or bodily injury of an agent, employee, customer, business invitee or business visitor or other person caused by the tortious or criminal conduct of the other Party; or (b) the damage, loss or destruction of real or tangible personal property caused by the tortious or criminal conduct of the other Party.
