iSHARES® YIELD OPTIMIZED BOND ETF
Ticker: BYLD Stock Exchange: NYSE Arca
 
Investment Objective
 
The iShares Yield Optimized Bond ETF (the “Fund”) seeks to track the investment results of an index composed of underlying fixed income funds that collectively seek to deliver current income.
 
Fees and Expenses
 
The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses. The Fund will also pay Acquired Fund Fees and Expenses. “Acquired Fund Fees and Expenses” reflect the Fund's pro rata share of the fees and expenses incurred by investing in other investment companies. As the Fund has not commenced operations prior to the date of this prospectus (the “Prospectus”), Acquired Fund Fees and Expenses are based on an estimate of the Fund’s allocation to other investment companies for the current fiscal year. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not used to calculate the Fund's net asset value per share (“NAV”). BFA, the investment adviser to the Fund, has contractually agreed to waive a portion of its management fees in an amount equal to the Acquired Fund Fees and Expenses attributable to the Fund's investments in other iShares funds until February 29, 2016. The contractual waiver may be terminated prior to February 29, 2016 only upon written agreement of the Trust and BFA.
 
You may also incur usual and customary brokerage commissions 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)

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    
  $29   $122    
Portfolio Turnover. The Fund and the other funds in which the Fund invests (each, an “Underlying Fund” and collectively, the “Underlying Funds”), may pay transaction costs, such as commissions, when they buy and sell securities (or “turn over” their portfolios). A higher portfolio turnover rate for the Fund or Underlying Funds may indicate higher transaction costs and cause the Fund or Underlying Funds to incur increased expenses. These expenses, which are not reflected in the Annual Fund Operating Expenses or in the Example (except costs to Underlying Funds included as part of Acquired Fund Fees and Expenses), affect the Fund's performance. To the extent the Underlying Funds incur costs from high portfolio turnover, such costs may have a negative effect on the performance of the Fund.
 
Principal Investment Strategies
 
The Fund is a fund of funds and seeks to track the investment results of the Morningstar U.S. Bond Market Yield-Optimized Index (the “Underlying Index”). The Fund invests primarily in Underlying Funds that themselves seek investment results corresponding to their own underlying indexes. The Fund also invests in a combination of other
 
exchange-traded funds (“ETFs”) (including other iShares ETFs), cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates (“BlackRock Cash Funds”).
 
The Underlying Index is a broadly diversified fixed income index that seeks to deliver current income. The Underlying Index is comprised of Underlying Funds within fixed income sectors that collectively have demonstrated relatively high risk adjusted income on a consistent basis and meet liquidity characteristics as determined by Morningstar Inc.’s (“Morningstar”) proprietary index methodology. The goal of the Underlying Index is to represent an allocation to four distinct fixed income sectors, with the exposure to each sector capped at a specified amount of the Underlying Index. The four sectors currently included in the Underlying Index and each sector's respective current caps are: no more than 50% government related fixed income securities, no more than 50% securitized fixed income securities, no more than 50% investment-grade credit securities and no more than 20% non-investment-grade credit securities. These four sectors are represented by Underlying Funds that the index provider, Morningstar, considers to deliver higher
 
S-2


Table of Contents
risk adjusted yields. Each fixed income sector has its own return and risk profile. The combined allocation percentages of the four represented sectors may equal less than 100%. The Underlying Index is rebalanced and reconstituted quarterly.
 
As of February 25, 2014, the Underlying Index included the following Underlying Funds within (i) the government related sector: iShares 1-3 Year Treasury Bond ETF, iShares 3-7 Year Treasury Bond ETF, iShares 7-10 Year Treasury Bond ETF, iShares 10-20 Year Treasury Bond ETF, iShares 20+ Year Treasury Bond ETF, iShares Agency Bond ETF and iShares TIPS Bond ETF; (ii) the securitized sector: iShares MBS ETF; (iii) the investment-grade credit sector: iShares 10+ Year Credit Bond ETF, iShares 1-3 Year Credit Bond ETF, iShares Floating Rate Bond ETF and iShares Intermediate Credit Bond ETF; and (iv) the non-investment-grade sector: iShares iBoxx $ High Yield Corporate Bond ETF. The Underlying Index may add, eliminate or replace Underlying Funds at any time. The Underlying Index may include large-, mid- or small-capitalization companies and securities issued by sovereign entities. The components of the Underlying Index primarily include industrials companies and mortgage-backed pass-through and treasury securities. The components of the Underlying Index, and the degree to which these components represent certain industries, may change over time.
 
BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive
positions when markets decline or appear overvalued.
Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.
BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund or an Underlying Fund may or may not hold all of the securities in its Underlying Index.
 
The Fund generally invests at least 90% of its assets in securities of the Underlying Index. However, the Fund may at times invest up to 20% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including BlackRock Cash Funds, as well as in individual securities and other ETFs (including other iShares ETFs) not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund
 
S-3


Table of Contents
seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.
The Fund may lend securities representing up to one-third of the value of the Fund's total assets (including the value of the collateral received).
The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is Morningstar.
Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.
Summary of Principal Risks
As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. The Fund is subject to the principal risks noted below (either directly or through its investments in the Underlying Funds), any of which may adversely affect the Fund's NAV, trading price, yield, total return and ability to meet its investment objective.
Affiliated Fund Risk. In managing the Fund, BFA will have the ability to select Underlying Funds and substitute other ETFs consistent with the sector allocations of the Underlying Index which it believes will achieve the Fund’s objective. BFA may be subject to potential conflicts of interest in selecting Underlying Funds and substituting other ETFs because the fees paid to BFA by some Underlying Funds and other ETFs managed by BFA may be higher than the fees paid by other Underlying Funds. If an Underlying Fund or other ETF holds interests in an affiliated fund, the Fund may be prohibited from purchasing shares of that Underlying Fund or other ETF.
Agency Debt Risk. The Fund or an Underlying Fund invests in unsecured bonds or debentures issued by government agencies, including the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”). Bonds or debentures issued by government agencies are generally backed only by the general creditworthiness and reputation of the government agency issuing the bond or debenture and are not backed by the full faith and credit of the U.S. government. As a result, there is uncertainty as to the current status of many obligations of Fannie Mae, Freddie Mac and other agencies that are placed under conservatorship of the federal government.
Allocation Risk. The Fund’s ability to achieve its investment objective depends upon BFA’s ability to accurately assess the Fund’s asset class allocation and select an appropriate mix of Underlying Funds and other ETFs to track the Underlying Index. There is a risk that BFA’s evaluations and
S-4


Table of Contents
assumptions regarding asset classes, Underlying Funds or other ETFs may be incorrect in view of actual market conditions. Further, the Fund’s Underlying Index may overweight certain asset classes relative to market capitalization weighted U.S. fixed income benchmarks. The Fund will underperform such benchmarks when asset classes overweighted in the Fund’s Underlying Index underperform other asset classes.
 
Asset Class Risk. Securities in the Underlying Index or in the Fund's portfolio may underperform in comparison to the general securities markets, a particular securities market, or other asset classes.
 
Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund or an Underlying Fund may “call” or repay the security before its stated maturity, and the Fund or an Underlying Fund may have to reinvest the proceeds at lower interest rates, resulting in a decline in the Fund's income.
 
Concentration Risk. The Fund may be susceptible to an increased risk of loss due to adverse occurrences to the extent that the Fund's or an Underlying Fund's investments are concentrated in a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class.
 
Credit Risk. Debt issuers and other counterparties may not honor their obligations or may have their debt downgraded by ratings agencies.
 
Custody Risk. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.
 
Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than those of other asset classes.
Extension Risk. During periods of rising interest rates, certain debt obligations will be paid off substantially more slowly than originally anticipated and the value of those securities may fall sharply, resulting in a decline in the Fund’s income and potentially in the value of the Fund’s investments.
Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund or an Underlying Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund's investments in the affected region.
 
High Yield Securities Risk. Securities that are rated below investment-grade (commonly referred to as “junk bonds,” including those bonds rated lower than “BBB-” by Standard & Poor's Ratings Services and Fitch, Inc. (“Fitch”) or “Baa3” by Moody's Investors Service, Inc. (“Moody's”)), or are unrated, may be deemed speculative and may be more volatile than higher-rated securities of similar maturity.
 
Income Risk. The Fund's income may decline due to a decline in inflation, deflation or changes in inflation expectations.
Index-Related Risk. There is no guarantee that the Fund will achieve a high degree of correlation to the Underlying Index and therefore achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to
S-5


Table of Contents
the required levels in order to track the Underlying Index. Errors in index data may occur from time to time and may not be identified and corrected for a period of time, and may have an adverse impact on the Fund and its shareholders.
Industrials Sector Risk. The industrials sector may be affected by changes in the supply and demand for products and services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors.
Interest Rate Risk. An increase in interest rates may cause the value of fixed-income securities held by the Fund or an Underlying Fund to decline.
Investment in Underlying Funds Risk. The Fund expects to invest substantially all of its assets in the Underlying Funds, so the Fund’s investment performance is directly related to the performance of the Underlying Funds. The Fund’s NAV will change with changes in the value of the Underlying Funds and other securities in which the Fund invests based on their market valuations. An investment in the Fund will entail more costs and expenses than a direct investment in the Underlying Funds.
As the Underlying Funds, or the Fund’s allocations among the Underlying Funds, change from time to time, or to the extent that the expense ratio of any Underlying Fund changes, the weighted average operating expenses borne by the Fund may increase or decrease.
 
Through an investment in Underlying Funds, the Fund may be exposed to Management Risk, Market Risk, Market Trading Risk, Passive Investment Risk, and Tracking Error Risk.
 
Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund or an Underlying Fund has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.
Liquidity Risk. Liquidity risk exists when particular investments are difficult to purchase or sell. This can reduce the Fund's returns because the Fund or an Underlying Fund may be unable to transact at advantageous times or prices.
Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA's investment strategy may not produce the intended results.
Market Risk. The Fund and Underlying Funds could lose money over short periods due to short-term market movements and over longer periods during market downturns.
Market Trading Risk. The Fund and the Underlying Funds face numerous market trading risks, including the potential lack of an active market for their shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund or Underlying Funds. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.
 
Model Risk. Neither the Fund nor BFA can offer assurances that the Underlying Index's allocation model will achieve its intended results or maximize returns or minimize risk, or be appropriate for every investor seeking a particular risk profile.
 
S-6


Table of Contents
Mortgage-Backed Securities Risk. Certain Underlying Funds invest in mortgage-backed securities (“MBS”), some of which may not be backed by the full faith and credit of the U.S. government. MBS are subject to call risk and extension risk. Because of these risks, MBS react differently than other bonds to changes in interest rates. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain MBS. Default or bankruptcy of a counterparty to a to-be-announced (“TBA”) transaction would expose the Fund to possible loss.
 
North American Economic Risk. Economic events in any one North American country can have a significant economic effect on the entire North American region and on some or all of the North American countries in which the Fund or the Underlying Funds invest.
 
Passive Investment Risk. The Fund and Underlying Funds are not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.
Privately-Issued Securities Risk. The Fund or Underlying Funds may invest in privately-issued securities, including those that are normally purchased pursuant to Rule 144A or Regulation S promulgated under the Securities Act of 1933, as amended (the “1933 Act”). Privately-issued securities are securities that have not been registered under the 1933 Act and as a result are subject to legal restrictions on resale. Privately-issued securities are not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. Delay or difficulty
in selling such securities may result in a loss to the Fund.
Reinvestment Risk. The Fund or an Underlying Fund may invest a portion of its assets in short-term fixed-income instruments and, as a result, may be adversely affected if interest rates fall because they may have to invest in lower yielding bonds as bonds in the Underlying Index are substituted.
 
Risk of Investing in the United States. The Fund and certain Underlying Funds have significant exposure to United States issuers. 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 or the Underlying Funds have exposure.
 
Savings Association Risk. Savings associations are affected by extensive regulations, interest rate increases, loan losses, decreased availability of money or asset valuation and market conditions. Recently, the deterioration of the credit market has had an adverse impact on savings associations.
 
Securities Lending Risk. The Fund or an Underlying Fund may engage in securities lending. Securities lending involves the risk that the Fund or an Underlying Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund or an Underlying Fund could also lose money in the event of a decline in the value of the 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.
 
S-7


Table of Contents
 
Sovereign Obligations Risk. The Fund and certain Underlying Funds invest in securities issued by or guaranteed by non-U.S. sovereign governments, which may be unable or unwilling to repay principal or interest when due. In times of economic uncertainty, the prices of these securities may be more volatile than those of corporate debt obligations or of other government debt obligations.
 
Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities held in the Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs, the Fund’s holding of cash, differences in timing of the accrual of dividends, changes to the Underlying Index or the need to meet various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.
U.S. Government Issuers Risk. Obligations of U.S. government agencies and authorities are supported by varying degrees of credit, but generally are not backed by the full faith and credit of the U.S. government. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government or U.S. government agencies and authorities may cause the value of the Fund's investments to decline.
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 or an Underlying Fund's U.S. Treasury obligations to decline.
Performance Information
As of the date of the Fund's prospectus (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. James Mauro and Scott Radell (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Mauro and Mr. Radell have been Portfolio Managers of the Fund since its inception.
 
Purchase and Sale of Fund Shares
 
The Fund is an ETF. Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than at NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund's distributor. The Fund generally will issue or redeem
 
S-8


Table of Contents
Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.
Tax Information
The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an individual retirement account (“IRA”).
Payments to Broker-Dealers and other Financial Intermediaries
If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank),
BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund
This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.
 
BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.
 
ETFs are funds that trade like other publicly traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by Authorized Participants (as defined in the Creations and Redemptions section of this Prospectus). Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.
An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the divergence of the performance (return) of the Fund's portfolio from that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.
An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.
The Fund's investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks
The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. The Fund may be exposed to these risks directly, or indirectly through the Fund's investments in the Underlying Funds. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.
Affiliated Fund Risk. In managing the Fund, BFA will have the ability to select Underlying Funds and substitute other ETFs consistent with the sector allocations of the Underlying Index which it believes will achieve the Fund’s objective. BFA may be subject to potential conflicts of interest in selecting Underlying Funds and substituting other ETFs because the fees paid to BFA by some Underlying Funds and other ETFs managed by BFA may be higher than the fees paid by other Underlying Funds. If an Underlying Fund or other ETF holds interests in an affiliated fund, the Fund may be prohibited from purchasing shares of that Underlying Fund or other ETF.
Agency Debt Risk. The Fund or an Underlying Fund invests in uncollateralized bonds or debentures issued by government agencies, including Fannie Mae and Freddie Mac. Bonds or debentures issued by government agencies are generally backed only by the general creditworthiness and reputation of the government agency issuing the bond or debenture and are not backed by the full faith and credit of the U.S. government.
 
Some government agencies, including Fannie Mae and Freddie Mac, purchase and guarantee residential mortgages and form MBS that they issue to the market. These agencies also hold their own MBS as well as those of other institutions with funding from the agency debentures they issue. The market for MBS has been adversely affected by the value of those MBS held and/or issued by these agencies.
 
Fannie Mae and Freddie Mac were placed under the conservatorship of the U.S. Federal Housing Finance Agency (“FHFA”) in September 2008. Under this conservatorship, the FHFA will operate and manage the agencies, and the U.S. Department of the Treasury has agreed to provide capital as needed (up to $100 billion per agency) to ensure that the agencies continue to provide liquidity to the housing and mortgage markets. It is unclear what effect this conservatorship will have on the securities issued or guaranteed by Fannie Mae or Freddie Mac. As a result, these securities are subject to more credit risk than U.S. government securities that are supported by the full faith and credit of the United States (e.g., U.S. Treasury bonds).
Allocation Risk. The Fund’s ability to achieve its investment objective depends upon BFA’s ability to accurately assess the Fund’s asset class allocation and select an appropriate mix of Underlying Funds and other ETFs to track the Underlying Index. There is a risk that BFA’s evaluations and assumptions regarding asset classes, Underlying Funds or other ETFs may be incorrect in view of actual market conditions. Further, the Fund’s Underlying Index may overweight certain asset classes relative to market capitalization weighted U.S. fixed income benchmarks. The Fund will underperform such benchmarks when asset classes overweighted in the Fund’s Underlying Index underperform other asset classes.

Table of Contents
Asset Class Risk. The securities in the Underlying Index or in the Fund’s or an Underlying Fund's portfolio may underperform the returns of other securities or indexes that track other industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.
Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund or an Underlying Fund may “call” or repay the security before its stated maturity, which may result in the Fund or an Underlying Fund having to reinvest the proceeds at lower interest rates, resulting in a decline in the Fund’s income.
 
Concentration Risk. To the extent that the Fund's or an Underlying Fund's investments are concentrated in the securities of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be more adversely affected by the underperformance of those securities, may be subject to 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.
Credit Risk. Credit risk is the risk that an issuer or guarantor of debt instruments 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 or to otherwise honor its obligations. Debt instruments are subject to varying degrees of credit risk, which may be reflected in their credit ratings. There is the chance that the Fund’s or an Underlying Fund's portfolio holdings will have their credit ratings downgraded or will default (i.e., fail to make scheduled interest or principal payments), potentially reducing such Fund’s  or an Underlying Fund's income level or share price, which can adversely affect the value of the Fund.
Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades and the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that may not be subject to independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities market is, the greater the likelihood of custody problems.
 
Equity Securities Risk. Certain Underlying Funds invest in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.
Extension Risk. During periods of rising interest rates, certain debt obligations will be paid off substantially more slowly than originally anticipated and the value of those securities may fall sharply, resulting in a decline in the Fund’s or an Underlying Fund's income and potentially in the value of the Fund’s or an Underlying Fund's investments.

Geographic Risk. Some of the markets in which the Underlying Funds invest are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, drought, hurricanes or tsunamis and are economically sensitive to environmental events. Any such event may adversely impact the economies of these geographic areas, causing an adverse impact on the value of the Fund.
 
High Yield Securities Risk. Securities that are rated below investment-grade (commonly referred to as “junk bonds,” including those bonds rated lower than “BBB-” by Standard & Poor's Ratings Services and Fitch or “Baa3” by Moody’s), or are unrated, may be deemed speculative and may be more volatile than higher-rated securities of similar maturity.
 
High yield securities may also be subject to greater levels of credit or default risk than higher-rated securities. The value of high yield securities can be adversely affected by overall economic conditions, such as an economic downturn or a period of rising interest rates, and high yield securities may be less liquid and more difficult to sell at an advantageous time or price or to value than higher-rated securities.
In particular, high yield securities are often issued by smaller, less creditworthy countries and companies or by highly leveraged (indebted) countries and companies, which are generally less able than more financially stable countries and companies to make scheduled payments of interest and principal.
Income Risk. The Fund’s income may decline when interest rates fall. This decline can occur because an Underlying Fund must invest in lower-yielding bonds as bonds in its portfolio mature or an Underlying Fund otherwise needs to purchase additional bonds.
Index-Related Risk. The Fund seeks to achieve a return which corresponds generally to the price and yield performance, before fees and expenses, of the Underlying Index as published by the Index Provider. There is no assurance that the Index Provider will compile the Underlying Index accurately, or that the Underlying Index will be determined, composed or calculated accurately. While the Index Provider does provide descriptions of what the Underlying Index is designed to achieve, the Index Provider does not provide any warranty or accept any liability in relation to the quality, accuracy or completeness of data in respect of their indices, and does not guarantee that the Underlying Index will be in line with their described index methodology. BFA’s mandate as described in this Prospectus is to manage the Fund consistently with the Underlying Index provided to BFA. Consequently, BFA does not provide any warranty or guarantee for Index Provider errors. Errors in respect of the quality, accuracy and completeness of the data may occur from time to time and may not be identified and corrected for a period of time, particularly where the indices are less commonly used. Therefore, gains, losses or costs associated with Index Provider errors will generally be borne by the Fund and its shareholders. For example, during a period where the Fund’s Underlying Index contains incorrect constituents, the Fund would have market exposure to such constituents and would be underexposed to the Underlying Index’s other constituents. As such, errors may result in a negative or positive performance impact to the Fund and its shareholders. Shareholders should understand that any
4


Table of Contents
gains from Index Provider errors will be kept by the Fund and its shareholders and any losses resulting from Index Provider errors will be borne by the Fund and its shareholders.
 
Apart from scheduled rebalances, the Index Provider may carry out additional ad hoc rebalances to the Underlying Index in order, for example, to correct an error in the selection of index constituents. Where the Underlying Index of the Fund is rebalanced and the Fund in turn rebalances its portfolio to bring it in line with the Underlying Index, any transaction costs and market exposure arising from such portfolio rebalancing will be borne directly by the Fund and its shareholders. Unscheduled rebalances to the Underlying Index may also expose the Fund to tracking error risk, which is the risk that its returns may not track exactly those of the Underlying Index. Therefore, errors and additional ad hoc rebalances carried out by the Index Provider to the Underlying Index may increase the costs and market exposure risk of the Fund.
 
Similar risks exist for the Underlying Funds in tracking their underlying index, which may result in the Fund's performance deviating from the return of the Underlying Index.
 
Industrials Sector Risk. The value of securities issued by companies in the industrials sector may be affected by supply and demand, both for their specific product or service and for industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates may adversely affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage and product liability claims.
 
Interest Rate Risk. As interest rates rise, the value of a fixed-income security held by the Fund or an Underlying Fund is likely to decrease. Securities with longer durations tend to be more sensitive to interest rate changes, usually making them more volatile than securities with shorter durations. To the extent the Fund or an Underlying 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 or an Underlying Fund’s investments to decline significantly, which can adversely affect the value of the Fund.
Investment in Underlying Funds Risk. The Fund expects to invest substantially all of its assets in the Underlying Funds, so the Fund’s investment performance is directly related to the performance of the Underlying Funds. The Fund may also invest in other funds, including money market funds. The Fund’s NAV will change with changes in the value of the Underlying Funds and other securities in which the Fund invests based on their market valuations. An investment in the Fund will entail more direct and indirect costs and expenses than a direct investment in the Underlying Funds. For example, the Fund indirectly pays a portion of the expenses (including operating expenses and management fees) incurred by the Underlying Funds.
One Underlying Fund may buy the same securities that another Underlying Fund sells. Also, an investor in the Fund may receive taxable gains from portfolio transactions by
5


Table of Contents
 
the Underlying Funds, as well as taxable gains from transactions in shares of the Underlying Funds by the Fund. Certain of the funds may also hold common portfolio securities.
 
As the Underlying Funds, or the Fund's allocations among the Underlying Funds, change from time to time, or to the extent that the expense ratio of the Underlying Funds changes, the weighted average operating expenses borne by the Fund may increase or decrease.
Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.
Liquidity Risk. Liquidity risk exists when particular investments are difficult to purchase or sell. To the extent the Fund or an Underlying Fund invests in illiquid securities or securities that become less liquid, such investments may have a negative effect on the returns of the Fund because the Fund or an Underlying Fund may be unable to sell the illiquid securities at an advantageous time or price. To the extent that the Fund’s or an Underlying Fund's principal investment strategies involve investing in securities with substantial market and/or credit risk, the Fund will tend to have the greatest exposure to liquidity risk. Liquid investments may become illiquid after purchase by the Fund or an Underlying Fund, particularly during periods of market turmoil. Illiquid investments may be harder to value, especially in changing markets, and if the Fund or an Underlying Fund is forced to sell these investments to meet redemption requests or for other cash needs, the Fund may suffer a loss. 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 or an Underlying Fund.
 
Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.
Market Risk. The Fund and the Underlying Funds could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular asset classes or industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or group of industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk
Absence of Active Market. Although shares of the Fund and the Underlying Funds 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 and each Underlying Fund's shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund's and each Underlying Fund's primary listing is maintained. 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 and each Underlying Fund's shares may be less actively traded in certain markets than in others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund 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 and the Underlying Funds may trade in the secondary market at times when the Fund and the Underlying Funds do 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 and Underlying Funds accept purchase and redemption orders. If the Fund purchases shares of an Underlying Fund at a time when the market price of Underlying Fund shares is at a premium to their NAV or sells Underlying Fund shares when their market price is at a discount to their NAV, the Fund may incur losses.
 
Secondary market trading in Fund 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. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.
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 associated with short selling.
 
Shares of the Fund and the Underlying Funds May Trade at Prices Other Than NAV. Shares of the Fund and an Underlying Fund each trade on stock exchanges at prices at, above or below the Fund’s most recent NAV. The NAV of the Fund and each Underlying Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s or an Underlying Fund's holdings. The trading price of each of the Fund's and Underlying Funds' shares fluctuates continuously throughout trading hours based on both market supply of and demand for

Table of Contents
 
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. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund or the Underlying Funds, as applicable, are not likely to be sustained over the long term. While the creation/redemption feature is designed to make it more likely that the Fund’s  or an Underlying Fund's shares normally will trade on stock exchanges at prices close to the Fund’s or an Underlying Fund's next calculated NAV, exchange prices are not expected to correlate exactly with the NAV due to timing reasons, supply and demand imbalances and other factors. In addition, disruptions to creations and redemptions, including disruptions at market makers or Authorized Participants, or to market participants or during periods of significant market volatility, may result in trading prices for shares of the Fund or an Underlying Fund that differ significantly from its 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 or other charges imposed by brokers as determined by that broker. 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). 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.
 
Model Risk. Neither the Fund nor BFA can offer any assurance that the allocation model used to calculate the Underlying Index will achieve its intended results or maximize returns or minimize risks, nor can the Fund or BFA offer assurance that a particular allocation will be the appropriate allocation in all circumstances for every investor seeking a particular risk profile or time horizon.
 
Mortgage-Backed Securities Risk. Certain Underlying Funds invest in MBS issued by Fannie Mae, the Government National Mortgage Association (“GNMA”) or Freddie Mac. While securities issued by GNMA are backed by the full faith and credit of the U.S. government, securities issued by Fannie Mae and Freddie Mac are not backed by the full faith and credit of the U.S. government, and there can be no assurance that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so.
MBS represent interests in “pools” of mortgages and are subject to call risk, which is the risk that during periods of falling interest rates, an issuer of mortgages and other securities may be able to repay principal prior to the security’s maturity causing the Fund to have to reinvest in securities with a lower yield, resulting in a decline in the Fund’s income.
8


Table of Contents
MBS are also subject to extension risk, which is the risk that when interest rates rise, certain MBS will be paid off substantially more slowly than originally anticipated and the value of those securities may fall sharply, resulting in a decline in income and potentially in the value of the investment.
Because of call and extension risk, MBS react differently to changes in interest rates than other bonds. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain MBS. These securities are also subject to the risk of default on the underlying mortgage, particularly during periods of economic downturn.
Certain Underlying Funds seek to obtain exposure to the fixed-rate portion of U.S. agency mortgage-pass through securities, which represent a significant portion of the Underlying Index, primarily through TBA transactions. Default or bankruptcy of a counterparty to a TBA transaction would expose the Fund, through its investments in such an Underlying Fund, to possible loss because of adverse market action, expenses or delays in connection with the purchase or sale of the pools of mortgage-pass-through securities specified in the TBA transaction.
 
North American Economic Risk. Decreasing imports or exports, changes in trade regulations and/or an economic recession in any North American country can have a significant economic effect on the entire North American region, and on some or all of the North American countries in which the Fund invests.
The United States is Canada and Mexico's largest trading and investment partner. The Canadian and Mexican economies are significantly affected by developments in the U.S. economy. Since the implementation of the North American Free Trade Agreement (“NAFTA”) in 1994 among Canada, the United States and Mexico, total merchandise trade between the three countries has increased. To further this relationship, the three NAFTA countries entered into the Security and Prosperity Partnership of North America in March 2005, which may further affect Canada's and Mexico's dependency on the U.S. economy. Policy and legislative changes in one country may have a significant effect on North American markets generally, as well as the value of certain securities.
 
Passive Investment Risk. The Fund and Underlying Funds are not actively managed and may be affected by a general decline in market segments related to their Underlying Indexes. The Fund and Underlying Funds invest in securities included in, or representative of, the Underlying Index, regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.
 
Privately-Issued Securities Risk. The Fund or Underlying Funds may invest in privately-issued securities, including those that are normally purchased pursuant to Rule 144A or Regulation S of the 1933 Act. Privately-issued securities typically may be resold only to qualified institutional buyers, or in a privately negotiated transaction, or to a limited number of purchasers, or in limited quantities after they have been held for a specified period of time and other conditions are met for an exemption from registration. Because there may be relatively few potential purchasers for such securities, especially under adverse markets or economic conditions or in the event of adverse changes in the financial condition of the issuer, the Fund or an Underlying

Fund may find it more difficult to sell such securities when it may be advisable to do so or it may be able to sell such securities only at prices lower than if such securities were more widely held and traded. At times, it also may be more difficult to determine the fair value of such securities for purposes of computing the Fund’s NAV due to the absence of an active trading market. There can be no assurance that a privately-issued security that is deemed to be liquid when purchased will continue to be liquid for as long as it is held by the Fund or an Underlying Fund.
Reinvestment Risk. A Fund or an Underlying Fund may invest a portion of its assets in short-term fixed-income instruments and as a result, may be adversely affected when interest rates fall because they may have to invest in lower yielding bonds as bonds in the Underlying Index are substituted. This may cause the Fund's or an Underlying Fund’s income to decline, which may adversely affect the value of the Fund.
Risk of Investing in the United States. The Fund and certain Underlying Funds have significant exposure to United States issuers. Decreasing imports or exports, changes in trade regulations and/or an economic recession in the United States may have a material adverse effect on the U.S. economy and the securities listed on U.S. exchanges. The financial crisis that began in 2007 caused a significant decline in the value and liquidity of issuers in the United States. Policy and legislative changes in the United States are changing many aspects of financial and other regulation and may have a significant effect on the U.S. markets generally, as well as the value of certain securities. In addition, a continued rise in the U.S. public debt level or U.S. austerity measures may adversely affect U.S. economic growth and the securities to which the Fund has exposure.
 
Savings Associations Risk. Federally- and state-chartered savings associations, such as savings and loans and other “thrift” institutions, provide banking services, including mortgage lending, and operate under the supervisory authority of the Office of the Comptroller of the Currency. Such “thrift” institutions formerly operated under the supervisory authority of the Office of Thrift Supervision. These associations are subject to extensive regulation affecting the scope of their activities, the prices they can charge, and the amount of capital they must maintain. This regulation can have the effect of limiting the profitability of these associations and their profitability may change frequently. Savings associations may be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations and adverse conditions in other related markets. Recently, the deterioration of the credit markets has had an adverse impact in a broad range of mortgage, asset backed, auction rate and other markets, adversely affecting financial institutions, including savings associations.
 
Securities Lending Risk. The Fund or an Underlying Fund may engage in securities lending. Securities lending involves the risk that the Fund or an Underlying Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund or an Underlying Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund or an Underlying Fund. In addition, BlackRock Institutional Trust Company, N.A. (“BTC”), the Fund’s securities lending

agent, will take the tax impact to shareholders of substitute payments for dividends into account when managing the Fund’s securities lending program.
 
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 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 or Underlying Funds 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, including treasury obligations, to decline. During periods of economic uncertainty, the market prices of sovereign debt may be more volatile than prices of U.S. debt obligations and may affect the Fund's NAV. In the past, certain emerging market countries have encountered difficulties in servicing their debt obligations, withheld payments of principal and interest and declared moratoria on the payment of principal and interest on their sovereign debts. Several countries in which the Fund or an Underlying Fund invests have defaulted on their sovereign obligations in the past or encountered downgrades of their sovereign obligations, and those countries (or other countries) may default or risk further downgrades in the future.
Tracking Error Risk. Tracking error is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities held in the Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs, the Fund holding uninvested cash, differences in timing of the accrual of dividends, changes to the Underlying Index or the costs of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.
U.S. Government Issuers Risk. Obligations of U.S. government agencies and authorities are supported by varying degrees of credit but generally are not backed by the full faith and credit of the U.S. government. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government or U.S. government agencies and authorities may cause the value of the Fund's investments to decline. On August 5, 2011, Standard & Poor's Ratings Services downgraded U.S. Treasury securities from AAA rating to AA+ rating. A 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 Standard & Poor's Ratings Services may cause the value of the Fund’s U.S. Treasury obligations to decline.
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 or an Underlying Fund's U.S. Treasury obligations to decline. On August 5, 2011, Standard & Poor's
11


Table of Contents
Ratings Services downgraded U.S. Treasury securities from AAA rating to AA+ rating. A 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 Standard & Poor's Ratings Services may cause the value of the Fund’s U.S. Treasury obligations to decline.
A Further Discussion of Other Risks
The Fund may also be subject to certain other risks associated with its investments and investment strategies.
 
Central and South American Economic Risk. The economies of certain Central and South American countries have experienced high interest rates, economic volatility, inflation, currency devaluations, government defaults and high unemployment rates. In addition, commodities (such as oil, gas and minerals) represent a significant percentage of exports for these regions and as a result many economies in these regions are particularly sensitive to fluctuations in commodity prices. Adverse economic events in one country may have a significant adverse impact on other countries in these regions.
 
Consumer Services Industry Risk. The success of consumer product manufacturers and retailers (including food and drug retailers, general retailers, media, and travel and leisure) is tied closely to the performance of the domestic and international economy, interest rates, exchange rates and consumer confidence. The consumer services industry depends heavily on disposable household income and consumer spending. Companies in the consumer services industry may be subject to severe competition, which may also have an adverse impact on their profitability. Changes in consumer demographics and preferences may affect the success of consumer products.
 
 
European Economic Risk. The Economic and Monetary Union of the EU requires compliance with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro (the common currency of certain EU countries), the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners. The European financial markets have recently experienced volatility and adverse trends due to concerns about economic downturns or rising government debt levels in several European countries, including Greece, Ireland, Italy, Portugal and Spain. These events have adversely affected the exchange rate of the euro and may continue to significantly affect every country in Europe, including countries that do not use the euro.
Responses to the financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest and may limit future growth and economic recovery or have

other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. The impact of these actions, especially if they occur in a disorderly fashion, is not clear but could be significant and far-reaching.
Financials Sector Risk. Companies in the financials sector of an economy are often subject to extensive governmental regulation and intervention, which may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financials sector, including effects not intended by such regulation. The impact of recent or future regulation in various countries on any individual financial company or on the sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financials sector more severely than those of investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financials sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Insurance companies, in particular, may be subject to severe price competition and/or rate regulation, which may have an adverse impact on their profitability. In the recent past, deterioration of the credit markets impacted a broad range of mortgage, asset-backed, auction rate, sovereign debt and other markets, including U.S. and non-U.S. credit and interbank money markets, thereby affecting a wide range of financial institutions and markets. A number of large financial institutions have failed, merged with stronger institutions or have had significant government infusions of capital. Instability in the financial markets has caused certain financial companies to incur large losses. Some financial companies experienced declines in the valuations of their assets, took actions to raise capital (such as the issuance of debt or equity securities), or even ceased operations. Some financial companies borrowed significant amounts of capital from government sources and may face future government-imposed restrictions on their businesses or increased government intervention. Those actions caused the securities of many financial companies to decline in value. The financials sector is particularly sensitive to fluctuations in interest rates.
Mid-Capitalization Companies Risk. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and therefore the share price of an Underlying Fund that invests mostly in mid-capitalization companies may increase or decrease by a greater percentage than those of funds that invest solely in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than large-capitalization stocks to adverse business or economic developments and the stocks of mid-capitalization companies may be less liquid, making it difficult for an Underlying Fund to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

Non-U.S. Issuers Risk. Securities issued by non-U.S. issuers have different risks from securities issued by U.S. issuers. These risks include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in non-U.S. countries, and potential restrictions of the flow of international capital. Non-U.S. issuers may be subject to less governmental regulation than U.S. issuers. Moreover, individual non-U.S. economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rate of inflation, capital reinvestment, resource self-sufficiency and balance of payment positions. In addition, the value of these securities may fluctuate due to changes in the exchange rate of the issuer’s local currency against the U.S. dollar.
 
Oil and Gas Industry Risk. The profitability of companies in the oil and gas industry is related to worldwide energy prices, exploration costs and production spending. Companies in the oil and gas industry may be at risk for environmental damage claims and other types of litigation. Companies in the oil and gas industry may be adversely affected by natural disasters or other catastrophes, changes in exchange rates, interest rates, changes in prices for competitive energy services, economic conditions, tax treatment, government regulation and intervention, negative perception and unfavorable events in the regions where companies operate (e.g., expropriation, nationalization, confiscation of assets and property or imposition of restrictions on foreign investments and repatriation of capital, military coups, social unrest, violence or labor unrest). Companies in the oil and gas industry may have significant capital investments in, or engage in transactions involving, emerging market countries, which may heighten these risks.
 
Risk of Investing in Emerging Markets. Investments in emerging markets are subject to a greater risk of loss than investments in more developed markets. This is due to, among other things, the potential for greater market volatility, lower trading volume, inflation, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments than typically found in more developed markets. In addition, emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risks associated with custody of securities. In addition, emerging markets often have greater risk of capital controls through such measures as taxes or interest rate control. Certain emerging market countries may also lack the infrastructure necessary to attract large amounts of foreign trade and investment.
Local securities markets in emerging market countries may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times. Settlement procedures in emerging market countries are frequently less developed and reliable than those in the United States and other developed countries. In addition, significant delays may occur in certain markets in registering the transfer of securities. Settlement or registration problems may make it more difficult for an Underlying Fund to value its portfolio securities and could cause an Underlying Fund to miss attractive investment opportunities.

Investing in emerging market countries may involve a greater risk of loss than investing in developed markets due to expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested by certain emerging market countries.
 
Small-Capitalization Companies Risk. Stock prices of small-capitalization companies may be more volatile than those of larger companies and, therefore, the share price of an Underlying Fund that invests mostly in small-capitalization companies may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by mid- or large-capitalization companies. Stock prices of small-capitalization companies are generally more vulnerable than those of mid- or large-capitalization companies to adverse business and economic developments. Securities of small-capitalization companies may be thinly traded, making it difficult for the Underlying Fund to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making them more vulnerable to experiencing adverse effects due to the loss of personnel. Small-capitalization companies also normally have less diverse product lines than mid- or large-capitalization companies and are more susceptible to adverse developments concerning their products.

The Fund allocates and reallocates its assets among the Underlying Funds consistent with the allocation and reallocation of securities in the Underlying Index as determined by Morningstar. In addition to investing in the Underlying Funds, the Fund may borrow, lend its portfolio securities to brokers, dealers and financial institutions, and may invest the collateral in certain short-term instruments, either directly or through one or more money market funds, as described in greater detail in the Fund's SAI.
Certain Underlying Funds may invest in non-U.S. securities, emerging markets securities and debt instruments, which are subject to additional risks, as described in this Prospectus and in the Fund’s SAI. The investment model for the Underlying Index is intended to represent a fixed allocation strategy designed to deliver high current income.
The Underlying Funds
The Fund seeks to track the investment results of an index composed of underlying fixed-income funds that collectively seek to deliver high current income. Each Underlying Fund generally holds assets that form a sub-set of the securities comprising

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

21


Table of Contents
designed to provide inflation protection to investors. TIPS are income-generating instruments whose interest and principal payments are adjusted for inflation — a sustained increase in prices that erodes the purchasing power of money. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index, the consumer price index (“CPI”), and TIPS' principal payments are adjusted according to changes in the CPI. A fixed coupon rate is applied to the inflation-adjusted principal so that as inflation rises, both the principal value and the interest payments increase. This can provide investors with a hedge against inflation, as it helps preserve the purchasing power of an investment. Because of this inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds. The Barclays U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L) includes all publicly-issued U.S. Treasury inflation-protected securities that have at least one year remaining to maturity, are rated investment-grade and have $250 million or more of outstanding face value. In addition, the securities in the Barclays U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L) must be denominated in U.S. dollars and must be fixed-rate and non-convertible.

Management
Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund's investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.
Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.
 
For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund based on a percentage of the Fund's average daily net assets, at an annual rate of 0.28%. Because the Fund has been in operation for less than one full fiscal year, this percentage reflects the rate at which BFA will be paid. BFA has contractually agreed to waive a portion of its management fees in an amount equal to the Acquired Fund Fees and Expenses attributable to the Fund's investments in other iShares funds until February 29, 2016. The contractual waiver may be terminated prior to February 29, 2016 only upon written agreement of the Trust and BFA.
BFA is located at 400 Howard Street, San Francisco, CA 94105. It is an indirect wholly-owned subsidiary of BlackRock, Inc. (“BlackRock”). As of December 31, 2013, BFA and its affiliates provided investment advisory services for assets in excess of $4.32

trillion. BFA and its affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.
A discussion regarding the basis for the Trust's Board of Trustees' (the “Board”) approval of the Investment Advisory Agreement with BFA will be available in the Fund's semi-annual report for the six-month period ending April 30.
 
Portfolio Managers. James Mauro and Scott Radell are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his portfolio management team that have more limited responsibilities.
 
James Mauro has been employed by BFA and BTC as a portfolio manager since 2011. Prior to that, Mr. Mauro was a Vice President at State Street Global Advisors. Mr. Mauro has been a Portfolio Manager of the Fund since its inception.
Scott Radell has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a portfolio manager since 2004. Mr. Radell was a credit strategist from 2003 to 2004 and became a portfolio manager at BGFA and BGI in 2004. Mr. Radell has been a Portfolio Manager of the Fund since its 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. BFA wants you to know that it has relationships with certain entities that may give rise to conflicts of interest or the appearance of conflicts of interest. These entities are BFA’s affiliates, including BlackRock and the PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”).
The activities of BFA and the Affiliates in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and the Affiliates provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA and the Affiliates are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA or one or more of the Affiliates acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, adviser, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple
23


Table of Contents
business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA or an Affiliate seeks to perform investment banking or other services.
BFA or one or more Affiliates may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including 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 are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA or an Affiliate having positions that are adverse to those of the Fund.
No Affiliate is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund's investment activities 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.
The Fund may, from time to time, enter into transactions in which BFA’s or an Affiliate’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.
The Fund's activities may be limited because of regulatory restrictions applicable to one or more Affiliates, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate has developed or is trying to develop investment banking relationships or in which an Affiliate has significant debt or equity investments or other interests. The Fund also may invest in securities of companies for which an Affiliate provides or may in the future provide research coverage. An Affiliate may have business relationships with, and purchase, distribute or sell services or products from or to, distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates in connection with the Fund's portfolio investment transactions.
 
Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. BFA may receive compensation for managing the reinvestment of cash collateral. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA or the Affiliates may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund's SAI for further information.
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) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.
Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund's shares trade under the trading symbol “BYLD.”
 
Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. 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 a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity (which is often the case for funds that are newly launched or small in size). The Fund's spread may also be impacted by the liquidity of the underlying securities held by the Fund, particularly for newly launched or smaller iShares funds or in instances of significant volatility of the underlying securities.
 
The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund's shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: 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 NYSE Arca.
 
Although the SEC has granted an exemptive order to the Trust permitting registered investment companies and unit investment trusts that enter into a participation agreement with the Trust (“Investing Funds”) to invest in iShares Funds beyond the limits set forth in Section 12(d)(1) of the 1940 Act subject to certain terms and conditions, the exemptive order is not applicable to the Fund. Accordingly, Investing Funds must adhere to the limits set forth in Section 12(d)(1) of the 1940 Act when investing in the Fund.
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 all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.
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 supply of and demand for ETF shares and underlying securities held by the Fund, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the 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 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 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/or price quotations obtained from broker-dealers that may trade in the portfolio securities 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 United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and make no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the NYSE (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) 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 (b) U.S. fixed-income assets may be valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets, which includes the values of the Underlying Fund shares in which the Fund invests, less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.
 
The value of the securities and other assets and liabilities held by the Fund are determined pursuant to valuation policies and procedures approved by the Board. The Fund's assets and liabilities are valued on the basis of market quotations, when readily available.
Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.
Generally, trading in non-U.S. securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.
 
When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Trust's 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, 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, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Non-U.S. securities whose values are affected by volatility that occurs in U.S. markets for related or highly correlated assets (e.g., American Depositary Receipts, Global Depositary Receipts or ETFs) on a trading day after the close of non-U.S. securities markets may be fair valued.
Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the prices at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the

prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.
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. The Fund generally distributes its net capital gains, if any, to shareholders annually. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.
 
Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.
Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.
 
Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.
Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, 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, including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, regardless of how long you have held the Fund’s shares. Long-term capital gains and qualified dividend income are generally eligible for taxation at a maximum rate of 15% for non-corporate shareholders with incomes below approximately $400,000 ($450,000 if married and filing jointly), adjusted annually for inflation, and 20% for individuals with any income above these amounts that is net long-term capital gain or qualified dividend income. In addition, a 3.8% U.S. federal Medicare contribution tax is imposed on “net investment income,” including, but not limited to, interest, dividends,

Table of Contents
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.
Short term capital gains earned by an Underlying Fund will be ordinary income when distributed to the Fund and will not be offset by the Fund's capital losses.
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.
If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, 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.
 
A 30% withholding tax will be imposed on U.S.-source dividends, interest and other income items paid after June 30, 2014, and proceeds from the sale of property producing U.S.-source dividends and interest paid after December 31, 2016, 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 will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Table of Contents
Dividends, interest and capital gains earned by an Underlying Fund with respect to non-U.S. positions may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of an Underlying Fund at the close of a year consists of non-U.S. stocks or securities (generally, for this purpose, depositary receipts, no matter where traded, of non-U.S. companies are treated as “non-U.S.”) (and 50% of the total assets of the Fund at the close of the year consists of foreign securities, or, at the close of each quarter, shares of Underlying Funds), the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund or an Underlying Fund.
As the Fund invests in only a limited number of positions, the Fund may be required to defer for tax purposes significant amounts of realized losses on the sale of shares in Underlying Funds indefinitely.
If you are a resident or a citizen of the United States, by law, back-up withholding at a 28% 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 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund's distributor, BlackRock Investments, LLC (the “Distributor”), an affiliate of BFA.
 
A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities (including any portion of such securities for which cash may be substituted) and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund. However, creation and redemption baskets may differ.
30


Table of Contents
Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities (including any portion of such securities for which cash may be substituted) held by the Fund and a specified amount of cash. Except when aggregated in Creation Units, shares are not redeemable by the Fund.
The prices at which creations and redemptions occur are based on the next calculation of NAV after a creation or redemption order is received in an acceptable form under the authorized participant agreement.
Only an Authorized Participant may create or redeem Creation Units directly with the Fund.
As a result of any 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 under Rule 144A of the 1933 Act, will not be able to receive securities that are 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 and 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 and 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.

Table of Contents
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 an 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 an 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, market impact and other costs and expenses related to cash transactions. 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 March 20, 2014, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

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.

Table of Contents
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, 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 it is eligible to receive. Therefore, such payments 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 and each Underlying 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 more than 240 investment series or portfolios. The Trust was organized as a Delaware statutory trust on December 16, 1999 and is authorized to have multiple series or portfolios. The Trust is an open-end management investment company registered with the SEC under the 1940 Act. The offering of the Trust’s shares is registered under the Securities Act of 1933, as amended (the “1933 Act”). This SAI relates solely to the Fund.
The Fund is managed by BlackRock Fund Advisors (“BFA”), an indirect wholly-owned subsidiary of BlackRock, Inc., and generally seeks to track the investment results of the specific benchmark index identified in the Fund's Prospectus (the “Underlying Index”).
The Fund offers and issues shares at their net asset value per share (“NAV”) only in aggregations of a specified number of shares (“Creation Unit”), generally in exchange for a designated portfolio of securities (including any portion of such securities for which cash may be substituted) included in its Underlying Index (the “Deposit Securities”), together with the deposit of a specified cash payment (the “Cash Component”). Shares of the Fund are listed for trading on NYSE Arca (the “Listing Exchange”), a national securities exchange. Shares of the Fund are traded in the secondary market and elsewhere at market prices that may be at, above or below the Fund's NAV. Shares are redeemable only in Creation Units, and, generally, in exchange for portfolio securities and a Cash Component. Creation Units typically are a specified number of shares, generally 50,000 or multiples thereof.
The Trust reserves the right to permit or require that creations and redemptions of shares are effected fully or partially in cash. Shares may be issued in advance of receipt of Deposit Securities, subject to various conditions, including a requirement to maintain with the Trust a cash deposit equal to at least 105% and up to 115%, which percentage BFA may change from time to time, of the market value of the omitted Deposit Securities. 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 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 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 (i) following the initial 12-month period beginning upon the commencement of trading of Fund shares, there are fewer than 50 beneficial owners of shares of the Fund for 30 or more consecutive trading days, (ii) the value of the Underlying Index on which the Fund is based is no longer calculated or available, (iii) the “indicative optimized portfolio value” (“IOPV”) of the Fund is no longer calculated or available, or (iv) 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 through a broker, you will incur a brokerage commission determined by that broker.
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 IOPV for the Fund as calculated by an information provider or
1


Table of Contents
market data vendor. The Trust is not involved in or responsible for any aspect of the calculation or dissemination of the IOPVs and makes no representation or warranty as to the accuracy of the IOPVs.
An IOPV has an equity and fixed income securities component and a cash component. The equity and fixed income securities values included in an IOPV are the values of the Deposit Securities for the Fund. While the IOPV reflects the current value of the Deposit Securities required to be deposited in connection with the purchase of a Creation Unit, it does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time because the current portfolio of the Fund may include securities that are not a part of the current Deposit Securities. Therefore, the Fund’s IOPV disseminated during the Listing Exchange trading hours should not be viewed as a real-time update of the Fund’s NAV, which is calculated only once a day.
The cash component included in an IOPV consists of estimated accrued interest, dividends and other income, less expenses. If applicable, each IOPV also reflects changes in currency exchange rates between the U.S. dollar and the applicable currency.
The Trust reserves the right to adjust the share prices of the Fund in the future to maintain convenient trading ranges for investors. Any adjustments would be accomplished through stock splits or reverse stock splits, which would have no effect on the net assets of the Fund or an investor's equity interest in the Fund.
Investment Strategies and Risks
The Fund seeks to achieve its objective by investing primarily in securities that comprise the Underlying Index and through transactions that provide substantially similar exposure to securities in the Underlying Index. The Fund operates as an index fund and will not be actively managed. Adverse performance of a security in the Fund’s portfolio will ordinarily not result in the elimination of the security from the Fund’s portfolio.
The Fund engages in representative sampling, which is investing in a sample of securities selected by BFA to have a collective investment profile similar to that of the Fund's Underlying Index. Securities selected have aggregate investment characteristics (based on market capitalization and industry weightings), fundamental characteristics (such as return variability, earnings valuation and yield) and liquidity measures similar to those of the Underlying Index. A fund that uses representative sampling generally does not hold all of the securities that are in its underlying index.
 
The Fund generally invests at least 90% of its assets in securities of the Underlying Index. However, the Fund may at times invest up to 20% of its assets in certain futures, options and swap contracts, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates (“BlackRock Cash Funds”), as well as in individual securities and other exchange-traded funds (“ETFs”) (including other iShares ETFs) not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index, to the extent permitted under the 1940 Act. The Fund seeks to track the investment results of the Underlying Index before the fees and expenses of the Fund.
 
Set forth below is more detailed information regarding types of instruments in which the Underlying Funds, and in some cases the Funds, may invest, strategies BFA may employ in pursuit of an Underlying Fund's investment objective, and related risks.
 
Asset-Backed and Commercial Mortgage-Backed Securities.  Certain of the Underlying Funds may invest in asset-backed securities (“ABS”) and commercial mortgage-backed securities (“CMBS”). ABS are securities backed by installment contracts, credit-card receivables or other assets. CMBS are securities backed by commercial real estate properties. Both ABS and CMBS represent interests in “pools” of assets in which payments of both interest and principal on the securities are made on a regular basis. The payments are, in effect, “passed through” to the holder of the securities (net of any fees paid to the issuer or guarantor of the securities). The average life of ABS and CMBS varies with the maturities of the underlying instruments and, as a result of prepayments, can often be less than the original maturity of the assets underlying the securities. For this and other reasons, an ABS or CMBS’s stated maturity may be shortened, and the security’s total return may be difficult to predict precisely. Also see Mortgage Pass-Through Securities and Mortgage Securities below.
Beginning in the second half of 2007 through 2009, the market for ABS and mortgage-backed securities (“MBS”) experienced substantially, often dramatically, lower valuations and reduced liquidity. These instruments continue to be subject to liquidity constraints, price volatility, credit downgrades and increases in default rates and, therefore, may be more difficult to value and more difficult to dispose of than previously.

Table of Contents
Bonds. Certain of the Underlying Funds may invest in U.S. and non-U.S. dollar-denominated bonds. A bond is an interest-bearing security issued by a U.S. or non-U.S. company, or U.S. or non-U.S. governmental unit. The issuer of a bond has a contractual obligation to pay interest at a stated rate on specific dates and to repay principal (the bond’s face value) periodically or on a specified maturity date. Bonds generally are used by corporations and governments to borrow money from investors.
An issuer may have the right to redeem or “call” a bond before maturity, in which case a fund may have to reinvest the proceeds at lower market rates. Similarly, a fund may have to reinvest interest income or payments received when bonds mature, sometimes at lower market rates. Most bonds bear interest income at a “coupon” rate that is fixed for the life of the bond. The value of a fixed-rate bond usually rises when market interest rates fall, and falls when market interest rates rise. Accordingly, a fixed-rate bond’s yield (income as a percent of the bond’s current value) may differ from its coupon rate as its value rises or falls. When an investor purchases a fixed-rate bond at a price that is greater than its face value, the investor is purchasing the bond at a premium. Conversely, when an investor purchases a fixed-rate bond at a price that is less than its face value, the investor is purchasing the bond at a discount. Fixed-rate bonds that are purchased at a discount pay less current income than securities with comparable yields that are purchased at face value, with the result that prices for such fixed-rate securities can be more volatile than prices for such securities that are purchased at face value. Other types of bonds bear interest at an interest rate that is adjusted periodically. Interest rates on “floating rate” or “variable rate” bonds may be higher or lower than current market rates for fixed-rate bonds of comparable quality with similar final maturities. Because of their adjustable interest rates, the value of “floating rate” or “variable rate” bonds fluctuates much less in response to market interest rate movements than the value of fixed-rate bonds, but the value may decline if their interest rates do not rise as much, or as quickly, as interest rates in general. Each Underlying Fund may treat some of these bonds as having a shorter maturity for purposes of calculating the weighted average maturity of its investment portfolio. Generally, prices of higher quality issues tend to fluctuate less with changes in market interest rates than prices of lower quality issues and prices of longer maturity issues tend to fluctuate more than prices of shorter maturity issues. Bonds may be senior or subordinated obligations. Senior obligations generally have the first claim on a corporation’s earnings and assets and, in the event of liquidation, are paid before subordinated obligations. Bonds may be unsecured (backed only by the issuer’s general creditworthiness) or secured (backed by specified collateral).
Borrowing. The Fund may borrow as a temporary measure for extraordinary or emergency purposes, including to meet redemptions or to facilitate the settlement of securities or other transactions. Under normal market conditions, any borrowing by the Fund will not exceed 10% of the Fund’s net assets; however, the Fund generally does not intend to borrow money.
The purchase of securities while borrowings are outstanding may have the effect of leveraging the Fund. The incurrence of leverage increases the Fund’s exposure to risk, and borrowed funds are subject to interest costs that will reduce net income. Purchasing securities while borrowings are outstanding creates special risks, such as the potential for greater volatility in the net asset value of Fund shares and in the yield on the Fund’s portfolio. In addition, the interest expenses from borrowings may exceed the income generated by the Fund’s portfolio and, therefore, the amount available (if any) for distribution to shareholders as dividends may be reduced. BFA may determine to maintain outstanding borrowings if it expects that the benefits to the Fund’s shareholders will outweigh the current reduced return.
Certain types of borrowings by the Fund 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 from managing 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.
 
 
Corporate Bonds. Certain of the Underlying Funds may invest in investment grade and/or high yield corporate bonds. High yield corporate bonds may be deemed speculative and more volatile than higher rated securities of similar maturity. The investment return of corporate bonds reflects interest earned on the security and changes in the market value of the security. The market value of a corporate bond may be affected by changes in the market rate of interest, the credit rating of the corporation, the corporation’s performance and perceptions of the corporation in the market place. There is a risk that the issuers of the securities may not be able to meet their obligations on interest or principal payments at the time called for by an instrument.

Table of Contents
Currency Transactions. The Underlying Funds that may engage in currency transactions do not expect to engage in currency transactions for the purpose of hedging against declines in the value of the Underlying Funds' assets that are denominated in a non-U.S. currency. An Underlying Fund may enter into non-U.S. currency forward and non-U.S. currency futures contracts to facilitate local securities settlements or to protect against currency exposure in connection with its distributions to shareholders, but may not enter into such contracts for speculative purposes.
A forward currency contract is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract.
A currency futures contract is a contract involving an obligation to deliver or acquire the specified amount of a specific currency, at a specified price and at a specified future time. Currency futures contracts may be settled on a net cash payment basis rather than by the sale and delivery of the underlying currency. To the extent required by law, liquid assets committed to futures contracts will be maintained.
 
Foreign exchange transactions involve a significant degree of risk and the markets in which foreign exchange transactions are effected are highly volatile, highly specialized and highly technical. Significant changes, including changes in liquidity and prices, can occur in such markets within very short periods of time, often within minutes. Foreign exchange trading risks include, but are not limited to, exchange rate risk, counterparty risk, maturity gap, interest rate risk, and potential interference by foreign governments through regulation of local exchange markets, foreign investment or particular transactions in non-U.S. currency. If BFA utilizes foreign exchange transactions at an inappropriate time or judges market conditions, trends or correlations incorrectly, foreign exchange transactions may not serve their intended purpose of improving the correlation of the Fund's return with the performance of its Underlying Index and may lower the Underlying Fund’s return. Each Underlying Fund could experience losses if the value of its currency forwards, options or futures positions were poorly correlated with its other investments or if it could not close out its positions because of an illiquid market. In addition, each Underlying Fund could incur transaction costs, including trading commissions, in connection with certain non-U.S. currency transactions.
 
Diversification Status. The Fund is classified as “diversified.” With respect to 75% of the Fund's total assets, a “diversified” fund is limited by the 1940 Act such that it does not invest more than 5% of its total assets in securities of any one issuer and does not acquire more than 10% of the outstanding voting securities of any one issuer (excluding cash and cash items, government securities, and securities of other investment companies). The remaining 25% of the Fund's total assets may be invested in any manner.
The Fund intends to maintain the required level of diversification and otherwise conduct its operations so as to qualify as a regulated investment company (“RIC”) for purposes of the U.S. Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”) and to relieve the Fund of any liability for U.S. federal income tax to the extent that its earnings are distributed to shareholders, provided that the Fund satisfies a minimum distribution requirement. Compliance with the diversification requirements of the Internal Revenue Code may limit the investment flexibility of the Fund and may make it less likely that the Fund will meet its investment objective.
Equity Securities. Equity securities generally have greater price volatility than fixed-income securities. The market price of equity securities may go up or down, sometimes rapidly or unpredictably. Equity securities may decline in value due to factors affecting equity securities markets generally; particular industries, sectors or geographic regions represented in those markets; or individual issuers. The types of developments that may affect an issuer of an equity security include management performance, financial leverage and reduced demand for the issuer's goods or services. Common and preferred stock represent equity or ownership interests in an issuer. Preferred stock, however, pays dividends at a specified rate and has precedence over common stock in the payment of dividends. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds and preferred stock take precedence over the claims of those who own common stock.
 
Futures and Options. Futures contracts and options may be used by the Fund and certain of the Underlying Funds to simulate investment in their respective underlying index, to facilitate trading or to reduce transaction costs. The Fund or an Underlying Fund may enter into futures contracts and options that are traded on a U.S. or non-U.S. exchange. The Fund or an Underlying Fund will not use futures or options for speculative purposes. The Fund and each Underlying Fund intend to use futures and options in accordance with Rule 4.5 of the Commodity Exchange Act (“CEA”). BFA, with respect to the Fund and each Underlying Fund, has claimed an exclusion from the definition of the term “commodity pool operator” in accordance with Rule 4.5 so that BFA, with respect to the Fund, or an Underlying Fund is not subject to registration or regulation as a commodity pool operator under the CEA.

Table of Contents
Futures contracts provide for the future sale by one party and purchase by another party of a specified amount of a specific instrument or index at a specified future time and at a specified price. Stock index contracts are based on investments that reflect the market value of common stock of the firms included in the investments. The Fund or an Underlying Fund may enter into futures contracts to purchase securities indexes when BFA anticipates purchasing the underlying securities and believes prices will rise before the purchase will be made. 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 at a specified price (“exercise price”) within a specified period of time. A put option gives a holder the right to sell a specific security at an exercise price within a specified period of time. The initial purchaser of a call option pays the “writer” a premium, which is paid at the time of purchase and is retained by the writer whether or not such option is exercised. The Fund or an Underlying Fund may purchase put options to hedge its portfolio against the risk of a decline in the market value of securities held and may purchase call options to hedge against an increase in the price of securities it is committed to purchase. The Fund or an Underlying Fund may write put and call options along with a long position in options to increase its ability to hedge against a change in the market value of the securities it holds or is committed to purchase. Investments in futures contracts and other investments that contain leverage may require the Fund or such Underlying Fund to maintain liquid assets. Generally, the Fund or such Underlying 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 or such Underlying Fund maintains liquid assets in an amount at least equal to the Fund’s or an Underlying Fund's daily marked-to-market obligation (i.e., the Fund’s or an Underlying Fund's daily net liability, if any), rather than the contracts’ notional value (i.e., the value of the underlying asset). By maintaining assets equal to its net obligation under cash-settled futures contracts, the Fund or an Underlying Fund may employ leverage to a greater extent than if the Fund or such Underlying Fund set aside assets equal to the futures contracts’ full notional value. The Fund or an Underlying 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.
High Yield Securities. Non-investment grade or “high yield” fixed income or convertible securities commonly known to investors as “junk bonds” or “high yield bonds” are debt securities that are rated below investment grade by the major rating agencies or are unrated securities that Fund management believes are of comparable quality. While generally providing greater income and opportunity for gain, non-investment grade debt securities may be subject to greater risks than securities that have higher credit ratings, including a high risk of default, and their yields will fluctuate over time. High yield securities will generally be in the lower rating categories of recognized rating agencies (rated “Ba” or lower by Moody's Investors Service, Inc. (“Moody's”) or BB by Fitch Ratings, Inc. (“Fitch”) or “BB” or lower by Standard & Poor’s Ratings Services) or will be unrated. The credit rating of a high yield security does not necessarily address its market value risk, and ratings may from time to time change, positively or negatively, to reflect developments regarding the issuer’s financial condition. High yield securities are considered to be speculative with respect to the capacity of the issuer to timely repay principal and pay interest in accordance with the terms of the obligation and may have more credit risk than higher rated securities.
 
The major risks of high yield bond investments include the following:
High yield bonds may be issued by less creditworthy companies. These securities are vulnerable to adverse changes in the issuer’s industry and to general economic conditions. Issuers of high yield bonds may be unable to meet their interest or principal payment obligations because of an economic downturn, specific issuer developments or the unavailability of additional financing.
The issuers of high yield bonds may have a larger amount of outstanding debt relative to their assets than issuers of investment grade bonds. If the issuer experiences financial stress, it may be unable to meet its debt obligations. The issuer’s ability to pay its debt obligations also may be lessened by specific issuer developments, or the unavailability of additional financing. Issuers of high yield securities are often in the growth stage of their development and/or involved in a reorganization or takeover.
 
High yield bonds are frequently ranked junior to claims by other creditors. If the issuer cannot meet its obligations, the senior obligations are generally paid off before the junior obligations, which will potentially limit the Fund’s or an Underlying Fund's ability to fully recover principal or to receive interest payments when senior securities are in default. Thus, investors in high yield securities have a lower degree of protection with respect to principal and interest payments than do investors in higher rated securities.
 
High yield bonds frequently have redemption features that permit an issuer to repurchase the security from the
5


Table of Contents
  Fund or an Underlying Fund before it matures. If an issuer redeems the high yield bonds, the Fund or an Underlying Fund may have to invest the proceeds in bonds with lower yields and may lose income.
 
Prices of high yield bonds are subject to extreme fluctuations. Negative economic developments may have a greater impact on the prices of high yield bonds than on those of other higher rated fixed income securities.
High yield bonds may be less liquid than higher rated fixed income securities even under normal economic conditions. Under certain economic and/or market conditions, the Fund or an Underlying Fund may have difficulty disposing of certain high yield securities due to the limited number of investors in that sector of the market. There are fewer dealers in the high yield bond market, and there may be significant differences in the prices quoted for high yield bonds by dealers, and such quotations may not be the actual prices available for a purchase or sale. Because high yield bonds are less liquid, judgment may play a greater role in the prices and values generated for such securities than in the case of securities trading in a more liquid market.
 
The secondary markets for high yield securities are not as liquid as the secondary markets for higher rated securities. The secondary markets for high yield securities are concentrated in relatively few market makers and participants in the markets are mostly institutional investors, including insurance companies, banks, other financial institutions and mutual funds. In addition, the trading volume for high yield securities is generally lower than that for higher rated securities and the secondary markets could contract under adverse market or economic conditions independent of any specific adverse changes in the condition of a particular issuer. Under certain economic and/or market conditions, the Fund or an Underlying Fund may have difficulty disposing of certain high yield securities due to the limited number of investors in that sector of the market. A less liquid secondary market may adversely affect the market price of the high yield security, which may result in increased difficulty selling the particular issue and obtaining accurate market quotations on the issue when valuing the Fund’s or an Underlying Fund's assets. Market quotations on high yield securities are available only from a limited number of dealers, and such quotations may not be the actual prices available for a purchase or sale. When the secondary market for high yield securities becomes more illiquid, or in the absence of readily available market quotations for such securities, the relative lack of reliable objective data makes it more difficult to value such securities, and judgment plays a more important role in determining such valuations.
The Fund or an Underlying Fund may incur expenses to the extent necessary to seek recovery upon default or to negotiate new terms with a defaulting issuer.
The high yield bond markets may react strongly to adverse news about an issuer or the economy, or to the perception or expectation of adverse news, whether or not it is based on fundamental analysis. Additionally, prices for high yield securities may be affected by legislative and regulatory developments. These developments could adversely affect the Fund’s or an Underlying Fund's net asset value and investment practices, the secondary market for high yield securities, the financial condition of issuers of these securities and the value and liquidity of outstanding high yield securities, especially in a thinly traded market. For example, federal legislation requiring the divestiture by federally insured savings and loan associations of their investments in high yield bonds and limiting the deductibility of interest by certain corporate issuers of high yield bonds adversely affected the market in the past.
 
Illiquid Securities. The Fund and certain Underlying Funds may invest up to an aggregate amount of 15% of its net assets in illiquid securities (calculated at the time of investment). Illiquid securities may include securities subject to contractual or other restrictions on resale and other instruments that lack readily available markets, as determined in accordance with SEC staff guidance. The liquidity of a security relates to the ability to readily dispose of the security and the price to be obtained upon disposition of the security, which may be lower than would be obtained for a comparable, more liquid security. Illiquid securities may trade at a discount to comparable, more liquid investments and may impair the Fund’s ability to dispose of investments in a timely fashion at their expected price.
 
Inflation-Protected Obligations.  Certain of the Underlying Funds invest almost exclusively in inflation-protected public obligations of the U.S. Treasury, commonly known as “TIPS.” TIPS are a type of U.S. government obligation issued by the U.S. Treasury that are designed to provide inflation protection to investors. TIPS are income-generating instruments whose interest and principal payments are adjusted for inflation - a sustained increase in prices that erodes the purchasing power of money. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index, the consumer price index (“CPI”), and TIPS’ principal payments are adjusted according to changes in the CPI. A fixed-coupon rate is applied to the inflation-adjusted principal so that as inflation rises, both the principal value and the
6


Table of Contents
interest payments increase. This can provide investors with a hedge against inflation, as it helps preserve the purchasing power of an investment. Because of this inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds.
Investments in Underlying Funds. Each Underlying Fund is a type of investment company referred to as an ETF. Each Underlying Fund is designed to track a particular index and is advised by BFA. Shares of the Underlying Funds are listed for trading on national securities exchanges and trade throughout the day on those exchanges and other secondary markets. There can be no assurance that the requirements of the national securities exchanges necessary to maintain the listing of shares of the Underlying Funds will continue to be met. A national securities exchange may, but is not required to, remove the shares of the Underlying Funds from listing if (i) following the initial 12-month period beginning upon the commencement of trading of an Underlying Fund, there are fewer than 50 beneficial holders of the shares for 30 or more consecutive trading days, (ii) the value of the Underlying Fund's underlying index is no longer calculated or available, or (iii) any other event shall occur or condition exist that, in the opinion of the national securities exchange, makes further dealings on the national securities exchange inadvisable. A national securities exchange will remove the shares of an Underlying Fund from listing and trading upon termination of the Underlying Fund. Shares of each Underlying Fund trade on exchanges at prices at, above or below their most recent NAV. The per share NAV of each Underlying Fund is calculated at the end of each business day and fluctuates with changes in the market value of such Underlying Fund's holdings since the most recent calculation. The trading prices of an Underlying Fund's shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of an Underlying Fund's shares may deviate significantly from NAV during periods of market volatility. Any of these factors may lead to an Underlying Fund's shares trading at a premium or discount to NAV. Exchange prices are not expected to correlate exactly with an Underlying Fund's NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to an Underlying Fund's creations and redemptions or the existence of extreme market volatility may result in trading prices of Underlying Fund shares that differ significantly from NAV. If the Fund purchase shares of Underlying Funds at a time when the market price of an Underlying Fund's shares are at a premium to the NAV or sells at a time when the market price of an Underlying Fund is at a discount to the NAV, then the Fund may sustain losses.
As in the case of other publicly-traded securities, brokers' commissions on buying or selling shares of Underlying Funds will be based on negotiated commission rates at customary levels. An investment in an ETF generally presents the same primary risks as an investment in an open-end investment company that is not exchange-traded and that has the same investment objectives, strategies, and policies. However, ETFs are subject to the following risks that do not apply to an open-end investment company that is not exchange-traded: (i) the market price of the ETF's shares may trade at a discount to their net asset value; (ii) an active trading market for an ETF's shares may not develop or be maintained; or (iii) trading of an ETF's shares may be halted if the listing exchange's officials deem such action appropriate, the shares are delisted from the exchange, or the activation of market-wide “circuit breakers” (which are tied to large decreases in stock prices) halts stock trading generally.
 
Lending Portfolio Securities. The Fund may lend portfolio securities to certain borrowers determined to be creditworthy by BFA, including to 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 loans of 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 the value of any interest or cash or non-cash distributions paid on the loaned securities.
With respect to loans that are collateralized by cash, the borrower may be entitled to receive a fee based on the amount of cash collateral. The Fund or the Underlying Funds are 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 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 as 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
 
7


Table of Contents
 
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” or the “Trustees”).
The Fund retains a portion of the securities lending income and remits a remaining portion to BTC as compensation for its services as securities lending agent. Securities lending income is equal to the total of income earned from the reinvestment of cash collateral (and excludes collateral investment fees as defined below), and any fees or other payments to and from borrowers of securities. As securities lending agent, BTC bears all operational costs directly related to securities lending. The Fund is responsible for fees in connection with the investment of cash collateral received for securities on loan in a money market fund managed by BFA, 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% until December 31, 2014 and 0.05% thereafter (the “collateral investment fees”). Such money market fund shares will not be subject to a sales load, redemption fee, distribution fee or service fee.
Pursuant to the current securities lending agreement:
(i) Fund-of-Funds retain 75% of securities lending income (which excludes collateral investment fees); and (ii) this amount can never be less than 65% of the sum of securities lending income plus collateral investment fees.
Under the securities lending program the Fund is categorized into specific asset classes. The determination of the Fund’s asset class category (fixed income, domestic equity, international equity or fund-of-funds), each of which may be subject to a different fee arrangement, is based on a methodology agreed to between the Trust and BTC.
In addition, commencing the business day following the date that the aggregate securities lending income earned across the Exchange-Traded Fund Complex (as defined under “ManagementTrustees 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”) (or lesser amount as may be agreed to by the Fund and BTC), each Fixed Income Fund, pursuant to the securities lending agreement, will receive for the remainder of that calendar year securities lending income as follows:
(i) 80% of securities lending income (which excludes collateral investment fees); and (ii) this amount can never be less than 65% of the sum of securities lending income plus collateral investment fees.
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 the tax effects on shareholders of this difference into account in connection with the Fund’s securities lending program. Substitute payments received on tax-exempt securities loaned out will not be tax-exempt income.
 
Mortgage Pass-Through Securities. Certain of the Underlying Funds may invest in mortgage pass-through securities which are a category of pass-through securities backed by pools of mortgages and issued by the Government National Mortgage Association (“GNMA”), or by one of several U.S. government-sponsored enterprises, such as the FNMA, FHLMC, or FHLBs. In the basic mortgage pass-through structure, mortgages with similar issuer, term and coupon characteristics are collected and aggregated into a “pool” consisting of multiple mortgage loans. The pool is assigned a CUSIP number and undivided interests in the pool are traded and sold as pass-through securities. The holder of the security is entitled to a pro rata share of principal and interest payments (including unscheduled prepayments) from the pool of mortgage loans.
Mortgage securities issued by non-government entities may be subject to greater credit risk than those issued by government entities. The performance of privately-issued mortgage securities may depend on the integrity and competence of the institutions that originate the underlying mortgages, yet investors in these mortgage securities may have only limited access to information required to evaluate the practices of these mortgage originators. In order to prevent defaults by troubled mortgage borrowers, the sponsors of mortgage securities may have to renegotiate and investors in mortgage

securities may have to accept less favorable interest rates or other terms on the mortgages underlying these securities. Unanticipated mortgage defaults or renegotiations of mortgage terms are likely to depress the prices of related mortgage securities. Although mortgage securities may be supported by some form of government or private guarantee and/or insurance, there is no assurance that private guarantors or insurers will meet their obligations. Guarantees, insurance and other forms of credit enhancement supporting mortgage securities may also be insufficient to cover all losses on underlying mortgages if mortgage borrowers default at a greater than expected rate.
An investment in a specific pool of pass-through securities requires an analysis of the specific prepayment risk of mortgages within the covered pool (since mortgagors typically have the option to prepay their loans). The level of prepayments on a pool of mortgage securities is difficult to predict and can impact the subsequent cash flows and value of the mortgage pool. In addition, when trading specific mortgage pools, precise execution, delivery and settlement arrangements must be negotiated for each transaction. These factors combine to make trading in mortgage pools somewhat cumbersome. For these and other reasons, an Underlying Fund may obtain exposure to U.S. agency mortgage pass-through securities primarily through the use of “to-be-announced” or “TBA transactions.” “TBA” refers to a commonly used mechanism for the forward settlement of U.S. agency mortgage pass-through securities, and not to a separate type of mortgage-backed security. Most transactions in mortgage pass-through securities occur through the use of TBA transactions. TBA transactions generally are conducted in accordance with widely-accepted guidelines that establish commonly observed terms and conditions for execution, settlement and delivery. In a TBA transaction, the buyer and seller decide on general trade parameters, such as agency, settlement date, par amount, and price. The actual pools delivered generally are determined two days prior to the settlement date. An Underlying Fund may use TBA transactions in several ways. For example, an Underlying Fund may regularly enter into TBA agreements and “roll over” such agreements prior to the settlement date stipulated in such agreements. This type of TBA transaction is sometimes known as a “TBA roll.” In a “TBA roll,” an Underlying Fund generally will sell the obligation to purchase the pools stipulated in the TBA agreement prior to the stipulated settlement date and will enter into a new TBA agreement for future delivery of pools of mortgage pass-through securities. In addition, an Underlying Fund may enter into TBA agreements and settle such transactions on the stipulated settlement date by accepting actual receipt or delivery of the pools of mortgage pass-through securities stipulated in the TBA agreement. Default by or bankruptcy of a counterparty to a TBA transaction would expose an Underlying Fund to possible loss because of adverse market action, expenses or delays in connection with the purchase or sale of the pools of mortgage pass-through securities specified in the TBA transaction. To minimize this risk, an Underlying Fund will enter into TBA transactions only with established counterparties (such as major broker-dealers) and BFA will monitor the creditworthiness of such counterparties. The use of “TBA rolls” may cause an Underlying Fund to experience higher portfolio turnover and to pay higher capital gain distributions, which may result in larger amounts of short-term capital gains allocable to interestholders. The Underlying Funds maintain liquid assets in connection with TBA transactions.
Mortgage Securities. Certain of the Underlying Funds may invest in mortgage securities. Mortgage securities are issued by government and non-government entities such as banks, mortgage lenders, or other institutions. A mortgage security is an obligation of the issuer that is backed by a mortgage or pool of mortgages or a direct interest in an underlying pool of mortgages. Some mortgage securities, such as collateralized mortgage obligations, make payments of both principal and interest at a range of specified intervals; others make semi-annual interest payments at a pre-determined rate and repay principal at maturity (like a typical bond). Mortgage securities are based on different types of mortgages, including those on commercial real estate or residential properties. Stripped mortgage securities are created when the interest and principal components of a mortgage security are separated and sold as individual securities. In the case of a stripped mortgage security, the holder of the “principal-only” security (PO) receives the principal payments made by the underlying mortgage, while the holder of the “interest-only” security (IO) receives interest payments from the same underlying mortgage.
The value of mortgage securities may change due to shifts in the market's perception of the creditworthiness of issuers and changes in interest rates or liquidity. The value of some mortgage-backed securities may be particularly sensitive to changes in prevailing interest rates. In addition, regulatory or tax changes may adversely affect the mortgage securities market as a whole. Mortgage securities issued by non-government entities may be subject to greater credit risk than those issued by government entities. The performance of privately-issued mortgage securities may depend on the integrity and competence of the institutions that originate the underlying mortgages, yet investors in these mortgage securities may have only limited access to information required to evaluate the practices of these mortgage originators. In order to prevent defaults by troubled mortgage borrowers, the sponsors of mortgage securities may have to renegotiate and investors in mortgage securities may have to accept less favorable interest rates or other terms on the mortgages underlying these securities. Unanticipated mortgage defaults or renegotiations of mortgage terms are likely to depress the prices of related mortgage securities. Although mortgage securities may be supported by some form of government or private guarantee and/or

insurance, there is no assurance that private guarantors or insurers will meet their obligations. Guarantees, insurance and other forms of credit enhancement supporting mortgage securities may also be insufficient to cover all losses on underlying mortgages if mortgage borrowers default at a greater than expected rate.
Non-government mortgage securities may be subject to greater price changes than government issues. Mortgage securities are subject to prepayment risk. Prepayment risk is the risk that early principal payments made on the underlying mortgages, usually in response to a reduction in interest rates, will result in the return of principal to the investor, causing the investor to be invested subsequently at a lower current interest rate. Alternatively, in a rising interest rate environment, mortgage security values may be adversely affected when prepayments on underlying mortgages do not occur as anticipated, resulting in the extension of the security's effective maturity and the related increase in interest rate sensitivity of a longer-term instrument. The prices of stripped mortgage securities tend to be more volatile in response to changes in interest rates than those of non-stripped mortgage securities. In addition, although mortgages and mortgage-related securities are generally supported by some form of government or private guarantee and/or insurance, there is no assurance that private guarantors or insurers will meet their obligations.
Non-Diversification Risk. Certain of the Underlying Funds may be classified as “non-diversified.” This means that the Underlying Funds may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Underlying Funds may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.
Non-U.S. Securities and Emerging Markets Securities. The Fund and certain of the Underlying Funds may invest in securities of non-U.S. issuers. Investing in the securities of non-U.S. issuers involves special risks and considerations not typically associated with investing in U.S. issuers. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or potentially confiscatory taxation or war, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in non-U.S. countries, potential restrictions of the flow of international capital, generally less liquid and less efficient securities markets, generally greater price volatility, less publicly available information about issuers, the imposition of withholding or other taxes, higher transaction and custody costs, delays and risks attendant in settlement procedures, difficulties in enforcing contractual obligations, lesser liquidity and significantly smaller market capitalization of most non-U.S. securities markets, more substantial government interference with the economy and transaction costs of foreign currency conversions. Non-U.S. issuers may be subject to less governmental regulation than U.S. issuers. Moreover, individual foreign economies may differ favorably or unfavorably from the U.S. economy with respect to growth of gross domestic product (“GDP”), rate of inflation, capital reinvestment, resource self-sufficiency and balance of payment positions. In addition, changes in foreign exchange rates also will affect the value of securities denominated or quoted in currencies other than the U.S. dollar. Certain foreign markets have specific geographical risks such as a heightened likelihood of earthquakes, tsunamis, or volcanoes. Certain foreign markets also experience acts of terrorism, territorial disputes or other defense concerns. These situations may have a significant impact on the economies of, and investments in, these geographic areas.
The Fund and certain of the Underlying Funds may purchase publicly-traded common stocks of non-U.S. issuers. To the extent an Underlying Fund invests in securities of non-U.S. issuers, the Underlying Fund's investment in such securities may also be in the form of American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) and European Depositary Receipts (“EDRs”) (collectively, “Depositary Receipts”). Depositary Receipts are receipts, typically issued by a bank or trust company, that evidence ownership of underlying securities issued by a non-U.S. issuer. For ADRs, the depositary is typically a U.S. financial institution and the underlying securities are issued by a non-U.S. issuer. For other forms of Depositary Receipts, the depositary may be a foreign or a U.S. entity, and the underlying securities may have a foreign or a U.S. issuer. Depositary Receipts are not necessarily denominated in the same currency as their underlying securities. Generally, ADRs, in registered form, are designed for use in the U.S. securities markets, and EDRs, in bearer form, are designed for use in European securities markets. GDRs are tradable both in the United States and in Europe and are designed for use throughout the world. An Underlying Fund may invest in Depositary Receipts through “sponsored” or “unsponsored” facilities. A sponsored facility is established jointly by the issuer of the underlying security and a depositary, whereas a depositary may establish an unsponsored facility without participation by the issuer of the deposited security. Holders of unsponsored Depositary Receipts generally bear all the costs of such facilities and the depositary of an unsponsored facility frequently is under no obligation to distribute interestholder communications received from the issuer of the deposited security or to pass through voting rights to the holders of such receipts in respect of the deposited securities. The issuers of unsponsored Depositary Receipts are not obligated to disclose material information in the United States and, therefore, there may be less information
10


Table of Contents
available regarding such issuers and there may not be a correlation between such information and the market value of the Depositary Receipts.
Obligations of Foreign Governments, Supranational Entities and Banks. The Fund and certain of the Underlying Funds may invest in U.S. dollar-denominated short-term obligations issued or guaranteed by one or more foreign governments or any of their political subdivisions, agencies or instrumentalities that are determined by BFA to be of comparable quality to the other obligations in which the Underlying Funds may invest. Certain foreign governments, specifically foreign governments in emerging markets, historically have encountered difficulties in servicing their debt obligations, withheld payments of principal and interest, and declared moratoria on the payment of principal and interest on their sovereign debts. The Fund and certain of the Underlying Funds may also invest in debt obligations of supranational entities. Supranational entities include international organizations designated or supported by governmental entities to promote economic reconstruction or development and international banking institutions and related government agencies. Examples include the International Bank for Reconstruction and Development (the World Bank), the Asian Development Bank and the InterAmerican Development Bank. The percentage of an Underlying Fund's assets invested in obligations of foreign governments and supranational entities will vary depending on the relative yields of such securities, the economic and financial markets of the countries in which the investments are made and the interest rate climate of such countries. The Fund and certain of the Underlying Funds may invest a portion of their total assets in high-quality, short-term (one year or less) debt obligations of foreign branches of U.S. banks or U.S. branches of foreign banks that are denominated in and pay interest in U.S. dollars.
Emerging Markets. Some non-U.S. markets in which certain of the Underlying Funds invest are considered to be emerging markets. Investment in these emerging markets subjects an Underlying Fund to a greater risk of loss than investments in developed markets. This is due to, among other things, greater market volatility, lower trading volume, political and economic instability, greater risk of market shut down and more governmental limitations on foreign investment policy than those typically found in developed markets.
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.
The Fund or an Underlying Fund may purchase and write put and call options on futures contracts that are traded on an exchange as a hedge against changes in value of its portfolio securities, or in anticipation of the purchase of securities, and may enter into closing transactions with respect to such options to terminate existing positions. There is no guarantee that such closing transactions can be effected.
Upon entering into a futures contract, the Fund or an Underlying 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 or an Underlying Fund upon termination of the futures contract, assuming 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 instrument or index underlying the futures contract fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as “marking-to-market.” At any time prior to the expiration of a futures contract, the Fund or an Underlying Fund may elect to close the position by taking an opposite position, which will operate to terminate the Fund’s or an Underlying Fund's existing position in the contract.
 
Ratings. An investment-grade rating means the security or issuer is rated investment-grade by Moody’s, Standard & Poor's Ratings Services, Fitch, or another credit rating agency designated as a nationally-recognized statistical rating organization (“NRSRO”) by the SEC, or is unrated but considered to be of equivalent quality by BFA. Bonds rated Baa3 or above by Moody’s
 
11


Table of Contents
or BBB- or above by Standard & Poor's Ratings Services and Fitch are considered “investment-grade” securities, bonds rated Baa are considered medium grade obligations subject to moderate credit risk and may possess certain speculative characteristics, while bonds rated BBB are regarded as having adequate capacity to meet financial commitments.
Subsequent to purchase by the applicable Underlying Fund, a rated security may cease to be rated or its rating may be reduced below an investment-grade rating. Bonds rated lower than Baa3 by Moody’s or BBB- by Standard & Poor's Ratings Services or Fitch are considered below investment-grade quality and are obligations of issuers that are considered predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal according to the terms of the obligation and, therefore, carry greater investment risk, including the possibility of issuer default and bankruptcy and increased market price volatility. Such securities (“lower-rated securities”) are commonly referred to as “junk bonds” and are subject to a substantial degree of credit risk. Lower-rated securities are often issued by smaller, less creditworthy companies or by highly leveraged (indebted) firms, which are generally less able than more financially stable firms to make scheduled payments of interest and principal. The risks posed by securities issued under such circumstances are substantial. Bonds rated below investment-grade tend to be less marketable than higher-quality bonds because the market for them is less broad. The market for unrated bonds is even narrower.

Regulation Regarding Derivatives. Effective December 31, 2012, the Commodity Futures Trading Commission (“CFTC”) adopted certain regulatory changes that subject registered investment companies and advisers to registered investment companies to regulation by the CFTC if funds that are registered investment companies, such as the Fund, invest more than a prescribed level of their liquidation value in CFTC-regulated futures, options and swaps (“CFTC Derivatives”), or if such funds market themselves as providing investment exposure to such instruments. To the extent the Fund uses CFTC Derivatives, it intends to do so below such prescribed levels and will not market itself as a “commodity pool” or a vehicle for trading such instruments. Accordingly, BFA has claimed an exclusion from the definition of the term “commodity pool operator” under the CEA pursuant to Rule 4.5 under the CEA. BFA is not, therefore, subject to registration or regulation as a “commodity pool operator” under the CEA in respect of the Fund.
The Fund may also have investments in “underlying funds” (and such underlying funds themselves may invest in underlying funds) not advised by BFA (which for purposes of the no-action letter referenced below may include certain securitized vehicles and/or mortgage real estate investment trusts (“REITs”) that may invest in CFTC Derivatives). BFA has no transparency into the holdings of these underlying funds because they are not advised by BFA. To address this issue of lack of transparency, the CFTC staff issued a no-action letter on November 29, 2012 permitting the adviser of a fund that invests in such underlying funds and that would otherwise have filed a claim of exclusion pursuant to Rule 4.5 to delay registration as a “commodity pool operator” until six months from the date on which the CFTC issues additional guidance on the treatment of CFTC Derivatives held by underlying funds. BFA, the adviser of the Fund, has filed a request with the CFTC to rely on this no-action relief.
 
Repurchase Agreements. A repurchase agreement is an instrument under which the purchaser (i.e., an Underlying Fund) acquires the security and the seller agrees, at the time of the sale, to repurchase the security at a mutually agreed upon time and price, thereby determining the yield during the purchaser’s holding period. Repurchase agreements may be construed to be collateralized loans by the purchaser to the seller secured by the securities transferred to the purchaser. If a repurchase agreement is construed to be a collateralized loan, the underlying securities will not be considered to be owned by an Underlying Fund but only to constitute collateral for the seller’s obligation to pay the repurchase price, and, in the event of a default by the seller, the  Underlying 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 rated in the highest rating category generally by at least two NRSROs, or, if unrated, determined to be of comparable quality by BFA. Collateral, however, is not limited to the foregoing and may include, for example, obligations rated below the highest category by NRSROs. Collateral for a repurchase agreement may also include securities that an Underlying Fund could not hold directly without the repurchase obligation. Irrespective of the type of collateral underlying the repurchase agreement, in the case of a repurchase agreement entered into by a non-money market fund, the repurchase obligation of a seller must be of comparable credit quality to securities that are rated in the highest two short-term credit rating categories by at least one NRSRO or, if unrated, deemed by BFA to be of equivalent quality.

Repurchase agreements pose certain risks for an Underlying Fund, should it decide to utilize them. Such risks are not unique to the  Underlying Funds, but are inherent in repurchase agreements. The  Underlying Funds seek to minimize such risks, but because of the inherent legal uncertainties involved in repurchase agreements, such risks cannot be eliminated. Lower quality collateral and collateral with longer maturities may be subject to greater price fluctuations than higher quality collateral and collateral with shorter maturities. 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, an Underlying Fund would retain the status of an unsecured creditor of the counterparty (i.e., the position the  Underlying Fund would normally be in if it were to hold, pursuant to its investment policies, other unsecured debt securities of the defaulting counterparty) with respect to the amount of the shortfall. As an unsecured creditor, an Underlying Fund would be at risk of losing some or all of the principal and income involved in the transaction.
Reverse Repurchase Agreements. Reverse repurchase agreements involve the sale of securities with an agreement to repurchase the securities at an agreed-upon price, date and interest payment and have the characteristics of borrowing. Generally, the effect of such transactions is that each Underlying Fund can recover all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement, while in many cases the Fund is able to keep some of the interest income associated with those securities. Such transactions are advantageous only if each Underlying Fund has an opportunity to earn a rate of interest on the cash derived from these transactions that is greater than the interest cost of obtaining the same amount of cash. Opportunities to realize earnings from the use of the proceeds equal to or greater than the interest required to be paid may not always be available and each Underlying Fund intends to use the reverse repurchase technique only when BFA believes it will be advantageous to the Underlying Fund. The use of reverse repurchase agreements may exaggerate any increase or decrease in the value of each Underlying Fund’s assets. An Underlying Fund’s exposure to reverse repurchase agreements will be covered by liquid assets having a value equal to or greater than such commitments. The use of reverse repurchase agreements is a form of leverage because the proceeds derived from reverse repurchase agreements may be invested in additional securities.
 
Securities of Investment Companies. Each Underlying Fund may invest in the securities of other investment companies (including money market funds) to the extent allowed by law, regulation, exemptive order or SEC staff guidance. Under the 1940 Act, an Underlying Fund’s investment in investment companies is limited to, subject to certain exceptions, (i) 3% of the total outstanding voting stock of any one investment company, (ii) 5% of the Underlying Fund’s total assets with respect to any one investment company, and (iii) 10% of the Underlying Fund’s total assets with respect to investment companies in the aggregate. To the extent allowed by law or regulation, each Underlying Fund intends from time to time to invest its assets in securities of investment companies, including but not limited to money market funds, including those advised by BFA or otherwise affiliated with BFA, in excess of the limits discussed above. Other investment companies in which an Underlying Fund invests can be expected to incur fees and expenses for operations, such as investment advisory and administration fees, that would be in addition to those incurred by an Underlying Fund.
 
An Underlying Fund may purchase shares of ETFs for the same reason it would purchase (and as an alternative to purchasing) futures contracts – to obtain relatively low-cost exposure to the stock market while maintaining flexibility to meet the liquidity needs of the Underlying Fund. ETF shares enjoy several advantages over futures. Depending on the market, the holding period, and other factors, ETF shares can be less costly than futures. In addition, ETF shares can be purchased for smaller sums and offer exposure to market sectors and styles for which there is no suitable or liquid futures contract. An Underlying Fund may also purchase ETF shares for other purposes, including improving its ability to track its underlying index. An Underlying Fund may invest in shares of ETFs that are advised by BFA.
Short-Term Instruments and Temporary Investments. The Fund and the Underlying Funds 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. (“Moody's”), “F-1” by Fitch Ratings, Inc. (“Fitch”), or “A-1” by Standard & Poor's® Financial Services LLC, a subsidiary of The McGraw-Hill Companies, Inc. (“Standard & Poor's Ratings Services”), 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 satisfy the rating requirements set forth in Rule 2a-7 under the 1940
13

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 which 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 and certain of the Underlying Funds 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 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. 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.
Supranational Entities. The Underlying Funds may invest in debt securities of supranational entities. Examples of such entities include the International Bank for Reconstruction and Development (the World Bank), the European Steel and Coal Community, the Asian Development Bank and the Inter-American Development Bank. The government members, or “stockholders,” usually make initial capital contributions to the supranational entity and in many cases are committed to make additional capital contributions if the supranational entity is unable to repay its borrowings. There is no guarantee that one or more stockholders of a supranational entity will continue to make any necessary additional capital contributions. If such contributions are not made, the entity may be unable to pay interest or repay principal on its debt securities, and the Fund may lose money on such investments.
Swap Agreements. Swap agreements are contracts between parties in which one party agrees to make periodic payments to the other party based on the change in market value or level of a specified rate, index or asset. In return, the other party agrees to make periodic payments to the first party based on the return of a different specified rate, index or asset. Swap agreements will usually be performed on a net basis, with each Underlying Fund receiving or paying only the net amount of the two payments. The net amount of the excess, if any, of an Underlying 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 Underlying Fund.
The use of interest rate and index swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. These transactions generally do not involve the delivery of securities or other underlying assets or principal.
Tracking Stocks. A tracking stock is a separate class of common stock whose value is linked to a specific business unit or operating division within a larger company and is designed to “track” the performance of such business unit or division. The tracking stock may pay dividends to shareholders independent of the parent company. The parent company, rather than the business unit or division, generally is the issuer of tracking stock. However, holders of the tracking stock may not have the same rights as holders of the company’s common stock.
U.S. Government Obligations. The Fund may invest in various types of U.S. government obligations. U.S. government obligations are a type of bond and include securities issued or guaranteed as to principal and interest by the U.S. government, its agencies or instrumentalities. Payment of principal and interest on U.S. government obligations (i) may be backed by the full faith and credit of the United States or (ii) may be backed solely by the issuing or guaranteeing agency or instrumentality itself (as with Federal National Mortgage Association (“Fannie Mae”), Federal Home Loan Mortgage Corporation (“Freddie Mac”) and Federal Home Loan Bank (“FHLB”) notes). In the latter case, the Fund must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be
14

privately owned. There can be no assurance that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so. As a general matter, the value of debt instruments, including U.S. government obligations, declines when market interest rates increase and rises when market interest rates decrease. Certain types of U.S. government obligations are subject to fluctuations in yield or value due to their structure or contract terms.
In 2008, Fannie Mae and Freddie Mac were placed under the conservatorship of the U.S. Federal Housing Finance Agency (“FHFA”). Under this conservatorship, the FHFA operates and manages the agencies, and the U.S. Department of Treasury has agreed to provide capital as needed (up to $100 billion per agency) to ensure that the agencies continue to provide liquidity to the housing and mortgage markets.
Future Developments. The board of each Underlying Fund may, in the future, authorize each Underlying Fund to invest in securities contracts and investments, other than those listed in this SAI and in the Prospectus, provided they are consistent with the Underlying Fund’s investment objective and do not violate any of its investment restrictions or policies.
General Considerations and Risks
A discussion of some of the principal risks associated with an investment in the Fund is contained in the Prospectus. Because the Fund expects to obtain its exposure to the securities in the Underlying Index substantially through its investment in the Underlying Funds, shareholders should be aware that the risks of investment in particular types of securities, economic sectors and geographic locations discussed below may be borne by the Fund through its investment in the Underlying Funds. Through its investment in the Underlying Funds, the Fund will also bear the risks described below associated with the Underlying Funds' use of portfolio management techniques, such as borrowing arrangements and use of derivatives, in addition to the risks associated with those activities if the Funds engage in them directly.
An investment in the Fund should be made with an understanding that the value of the Fund’s portfolio securities, including its investment in the Underlying Funds, 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.
Agency Debt Risk. The Fund or an Underlying Fund may invest in unsecured bonds or debentures issued by government agencies, including Fannie Mae or Freddie Mac. Bonds or debentures issued by government agencies are generally backed only by the general creditworthiness and reputation of the government agency issuing the bond or debenture and are not backed by the full faith and credit of the U.S. government.
Some government agencies, including Fannie Mae and Freddie Mac, purchase and guarantee residential mortgages and form mortgage-backed securities that they issue to the market. These agencies also hold their own mortgage-backed securities as well as those of other institutions with funding from the agency debentures they issue. Recent events in the markets for mortgage-backed securities have adversely affected the value of those mortgage-backed securities held and/or issued by these agencies.
Fannie Mae and Freddie Mac were placed under the conservatorship of the U.S. Federal Housing Finance Agency (“FHFA”) in September 2008. Under this conservatorship, the FHFA will operate and manage the agencies, and the U.S. Department of the Treasury has agreed to provide capital as needed (up to $100 billion per agency) to ensure that the agencies continue to provide liquidity to the housing and mortgage markets. It is unclear what effect this conservatorship will have on the securities issued or guaranteed by Fannie Mae or Freddie Mac. As a result, these securities are subject to more credit risk than U.S. government securities that are supported by the full faith and credit of the United States (e.g., U.S. Treasury bonds).
Borrowing Risk. Borrowing may exaggerate changes in the net asset value of Fund shares and in the return on the Fund’s portfolio. Borrowing will cost the Fund interest expense and other fees. The costs of borrowing may reduce the Fund’s return. Borrowing may cause the Fund to liquidate positions when it may not be advantageous to do so to satisfy its obligations.
 
Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund or an Underlying Fund may “call” or repay the security before its stated maturity, which may result in the Fund or an Underlying Fund having to reinvest the proceeds at lower interest rates, resulting in a decline in the Fund's income.

Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades and to the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that may not be subject to independent evaluation. Local agents are held only to the standards of care of their local markets, and thus may be subject to limited or no government oversight. Communications between the United States and emerging market countries may be unreliable, increasing the risk of delayed settlements or losses of security certificates. The less developed a country’s securities market is, the greater the likelihood of custody problems. Practices in relation to the settlement of securities transactions in emerging markets involve higher risks than those in developed markets, in part because of the use of brokers and counterparties that are less well capitalized, and custody and registration of assets in some countries may be unreliable. The possibility of fraud, negligence, undue influence being exerted by the issuer or refusal to recognize ownership exists in some emerging markets, and, along with other factors, could result in ownership registration being lost. In addition, the laws of certain countries may put limits on the Fund’s ability to recover its assets if a foreign bank or depository or issuer of a security or an agent of any of the foregoing goes bankrupt. The Fund would absorb any loss resulting from such custody problems and may have no successful claim for compensation.
Cyber Security Issues. With the increased use of technologies such as the Internet to conduct business, the Fund is susceptible to operational, information security and related risks. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber attacks include, but are not limited to, gaining unauthorized access to digital systems 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. Cyber security failures or breaches by the Fund’s third party service providers (including, but not limited to, index providers, fund accountants and transfer agents), market makers, Authorized Participants (as defined in the Portfolio Holdings Information section of this SAI) and the issuers of securities in which the Fund invests, have the ability to cause disruptions and impact business operations potentially resulting in financial losses, the inability of Fund shareholders 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, substantial costs may be incurred in order to prevent any 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. Furthermore, the Fund cannot control the cyber security plans and systems put in place by issuers in which the Fund invests, market makers or Authorized Participants. The Fund and its shareholders could be negatively impacted as a result.
Extension Risk. During periods of rising interest rates, certain obligations will be paid off substantially more slowly than originally anticipated and the value of those securities may fall sharply, resulting in a decline to the Fund’s income and potentially in the value of the Fund’s investments.
 
Operational Risk. BFA and the Fund’s other service providers may experience disruptions or operating errors 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. BlackRock, 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 BlackRock 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). Each Underlying Fund may invest in variable rate demand notes and obligations, and tender option bonds, which may be considered derivatives. Compared to conventional securities, derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices and thus 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.
Risk of Futures and Options Transactions. There are several risks accompanying the utilization of futures contracts and options on futures contracts. A position in futures contracts and options on futures contracts may be closed only on the exchange on which the contract was made (or a linked exchange). While each Underlying Fund plans to utilize futures
 
16

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. Furthermore, because, by definition, futures contracts project price levels in the future and not current levels of valuation, market circumstances may result in a discrepancy between the price of the bond index future and the movement in the relevant underlying indexes. 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 an Underlying 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, an Underlying 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. Each Underlying 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. Each Underlying Fund, however, intends to utilize futures and options contracts in a manner designed to limit its risk exposure to levels comparable to a direct investment in the types of bonds in which it invests.
Utilization of futures and options on futures by an Underlying Fund involves the risk of imperfect or even negative correlation to its underlying index if the index underlying the futures contract differs from the underlying index. There is also the risk of loss by an Underlying Fund of margin deposits in the event of bankruptcy of a broker with whom the Underlying 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 an Underlying Fund to substantial losses. In the event of adverse price movements, an Underlying Fund would be required to make daily cash payments of variation margin.
Risk of Investing in Non-U.S. Debt Securities. Certain of the Underlying Funds may invest in non-U.S. debt securities. An investment in the Underlying Funds involves risks associated with investing in a portfolio of debt securities traded on foreign exchanges and over-the-counter in the respective countries covered by the Underlying Funds. These risks typically include market fluctuations caused by such factors as economic and political developments, changes in interest rates and perceived trends in bond prices. Investing in an Underlying Fund whose portfolio contains non-U.S. issuers involves certain risks and considerations not typically associated with investing in the securities of U.S. issuers. These risks include generally less liquid and less efficient securities markets; generally greater price volatility; less publicly-available information about issuers; the imposition of withholding or other taxes; the imposition of restrictions on the expatriation of funds or other assets of the Underlying Funds; higher transaction and custody costs; delays and risks attendant in settlement procedures; difficulties in enforcing contractual obligations; lower liquidity and significantly smaller market capitalization of most non-U.S. securities markets; different accounting and disclosure standards; lower levels of regulation of the securities markets; more substantial government interference with the economy; higher rates of inflation; greater social, economic, and political uncertainty; and the risk of nationalization or expropriation of assets and risk of war.
Risk of Investing in Mid-Capitalization Companies. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, an Underlying Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it more difficult for the Underlying Funds to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies have and are more susceptible to adverse developments related to their products.
 
17


Table of Contents
 
Risk of Investing in Small-Capitalization Companies. Stock prices of small-capitalization companies may be more volatile than those of larger companies and therefore an Underlying Fund's share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of small-capitalization companies are generally more vulnerable than those of large-capitalization companies to adverse business and economic developments. The stocks of small-capitalization companies may be thinly traded, making it difficult for the Underlying Funds to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making them more vulnerable to loss of personnel. Small-capitalization companies also normally have less diverse product lines than those of large-capitalization companies and are more susceptible to adverse developments concerning their products.
Risk of Investing in Asia.  Investments in securities of issuers in certain Asian countries involve risks not typically associated with investments in securities of issuers in other regions. Such heightened risks  include, among others, expropriation and/or nationalization of assets, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision-making, armed conflict and social instability as a result of religious, ethnic and/or socio-economic unrest. Many Asian economies have experienced rapid rates of economic growth and industrialization in recent years, and there is no assurance that these rates of economic growth and industrialization will be maintained.
 
Certain Asian countries have democracies with relatively short histories, which may increase the risk of political instability. These countries have faced political and military unrest, and further unrest could present a risk to their local economies and securities markets. Indonesia and the Philippines have each experienced violence and terrorism, which has negatively impacted their economies. North Korea and South Korea each have substantial military capabilities, and historical tensions between the two countries present the risk of war; in the recent past, these tensions have escalated. Any outbreak of hostilities between the two countries could have a severe adverse effect on the South Korean economy and securities market. Increased political and social unrest in these geographic areas could adversely affect the performance of investments in this region.
Certain governments in this region administer prices on several basic goods, including fuel and electricity, within their respective countries. Certain governments may exercise substantial influence over many aspects of the private sector in their respective countries and may own or control many companies. Future government actions could have a significant effect on the economic conditions in this region, which in turn could have a negative impact on private sector companies. There is also the possibility of diplomatic developments adversely affecting investments in the region.
Corruption and the perceived lack of a rule of law in dealings with international companies in certain Asian countries may discourage foreign investment and could negatively impact the long-term growth of certain economies in this region. In addition, certain countries in the region are experiencing high unemployment and corruption, and have fragile banking sectors.
Some economies in this region are dependent on a range of commodities, including oil, natural gas and coal. Accordingly, they are strongly affected by international commodity prices and particularly vulnerable to any weakening in global demand for these products. The market for securities in this region may also be directly influenced by the flow of international capital, and by the economic and market conditions of neighboring countries. Adverse economic conditions or developments in neighboring countries may increase investors' perception of the risk of investing in the region as a whole, which may adversely impact the market value of the securities issued by companies in the region.
Risk of Investing in Central and South America. The economies of certain countries in which certain of the Underlying Funds invest are affected by the economies of other Central and South American countries, some of which have experienced high interest rates, economic volatility, inflation, currency devaluations, government defaults and high unemployment rates. In addition, commodities (such as oil, gas and minerals) represent a significant percentage of the region's exports and many economies in this region are particularly sensitive to fluctuations in commodity prices. Adverse economic events in one country may have a significant adverse effect on some or all of the countries in which the Underlying Fund invests.
 
Risk of Investing in Eastern Europe. Investing in the securities of issuers located or operating in Eastern Europe is highly speculative and involves risks not usually associated with investing in the more developed markets of Western Europe. Political and economic reforms are too recent to establish a definite trend away from centrally planned economies and state-owned industries. In the past, some Eastern European governments have expropriated substantial amounts of private property, and many claims of the property owners have never been fully settled.

Many Eastern European countries continue to move toward market economies at different paces with appropriately different characteristics. Most Eastern European securities markets suffer from thin trading activity, dubious investor protections, and often a dearth of reliable corporate information. Information and transaction costs, differential taxes, and sometimes political or transfer risk give a comparative advantage to the domestic investor rather than the foreign investor. In addition, these markets are particularly sensitive to social, political, economic, and currency events in Russia and may suffer heavy losses as a result of their trading and investment links to the Russian economy and currency. Russia also may attempt to assert its influence in the region through economic or even military measures, as it did with Georgia in the summer of 2008 and Ukraine in 2014. Eastern European economies may also be particularly susceptible to changes in the international credit markets due to their reliance on bank related inflows of capital. The global economic crisis has restricted international credit supplies, and several Eastern European economies have faced significant credit and economic crises. Although some Eastern European economies are expanding again, major challenges are still present as a result of their continued dependence on the Western European zone for credit.
 
Risk of Investing in Europe. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro (the common currency of certain EU countries), the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners. Although certain European countries do not use the euro, many of these countries are obliged to meet the criteria for joining the euro zone. Consequently, these countries must comply with many of the restrictions noted above. The European financial markets have recently experienced volatility and adverse trends due to concerns about economic downturns, rising government debt levels and the possible default of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. In order to prevent further economic deterioration, certain countries, without prior warning, can institute “capital controls.” Countries may use these controls to restrict volatile movements of capital entering and exiting their country. Such controls may negatively affect the Fund’s investments. A default or debt restructuring by any European country would adversely impact holders of that country's debt and sellers of credit default swaps linked to that country's creditworthiness, which may be located in countries other than those listed above. In addition, the credit ratings of certain European countries were recently downgraded. These downgrades may result in further deterioration of investor confidence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including countries that do not use the euro and non-EU member countries. Responses to the financial problems by European governments, central banks and others, including austerity measures and reforms, may not produce the desired results, may result in social unrest and may limit future growth and economic recovery or have other unintended consequences. Further defaults or restructurings by governments and other entities of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, one or more countries may abandon the euro and/or withdraw from the EU. The impact of these actions, especially if they occur in a disorderly fashion, is not clear but could be significant and far-reaching.
 
Risk of Investing in North America. Decreasing imports or exports, changes in trade regulations and/or an economic recession in any one North American country can have a significant economic effect on the entire North American region, and on some or all of the North American countries in which certain of the Underlying Funds invest.
The United States is Canada and Mexico's largest trading and investment partner. The Canadian and Mexican economies are significantly affected by developments in the U.S. economy. Since the implementation of the North American Free Trade Agreement (“NAFTA”) in 1994 among Canada, the United States and Mexico, total merchandise trade between the three countries has increased. To further this relationship, the three NAFTA countries entered into the Security and Prosperity Partnership of North America in March 2005, which may further affect Canada's and Mexico's dependency on the U.S. economy. Policy and legislative changes in one country may have a significant effect on North American markets generally, as well as the value of certain securities.
 
Risk of Investing in the Middle East. Many Middle Eastern countries have little or no democratic tradition, and the political and legal systems in such countries may have an adverse impact on the Fund. Many economies in the Middle East are highly reliant on income from the sale of oil or trade with countries involved in the sale of oil, and their economies are therefore vulnerable to changes in the market for oil and foreign currency values. As global demand for oil fluctuates, many Middle Eastern economies may be significantly impacted.

In addition, many Middle Eastern governments have exercised and continue to exercise substantial influence over many aspects of the private sector. In certain cases, a Middle Eastern country’s government may own or control many companies, including some of the largest companies in the country. Accordingly, governmental actions in the future could have a significant effect on economic conditions in Middle Eastern countries. This could affect private sector companies and certain of the Underlying Funds, as well as the value of securities in such Underlying Funds' portfolios.
Certain Middle Eastern markets are in the earliest stages of development. As a result, there may be a high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries, as well as a high concentration of investors and financial intermediaries. Brokers in Middle Eastern countries typically are fewer in number and less well capitalized than brokers in the United States.
 
The legal systems in certain Middle Eastern countries also may have an adverse impact on certain of the Underlying Funds. For example, the potential liability of a shareholder in a U.S. corporation with respect to acts of the corporation generally is limited to the amount of the shareholder’s investment. However, the notion of limited liability is less clear in certain Middle Eastern countries. Each such Underlying Fund therefore may be liable in certain Middle Eastern countries for the acts of a corporation in which it invests for an amount greater than its actual investment in that corporation. Similarly, the rights of investors in Middle Eastern issuers may be more limited than those of shareholders of a U.S. corporation. It may be difficult or impossible to obtain and/or enforce a legal judgment in a Middle Eastern country. Some Middle Eastern countries prohibit or impose substantial restrictions on investments in their capital markets, particularly their equity markets, by foreign entities such as an Underlying Fund. For example, certain countries may require governmental approval prior to investment by foreign persons or limit the amount of investment by foreign persons in a particular issuer. Certain Middle Eastern countries may also limit the investment by foreign persons to only a specific class of securities of an issuer that may have less advantageous terms (including price) than securities of the issuer available for purchase by nationals.
 
The manner in which foreign investors may invest in companies in certain Middle Eastern countries, as well as limitations on those investments, may have an adverse impact on the operations of an Underlying Fund. For example, in certain of these countries, an Underlying Fund may be required to invest initially through a local broker or other entity and then have the shares that were purchased re-registered in the name of the Fund. Re-registration in some instances may not be possible on a timely basis. This may result in a delay during which an Underlying Fund may be denied certain of its rights as an investor, including rights as to dividends or to be made aware of certain corporate actions. There also may be instances where an Underlying Fund places a purchase order but is subsequently informed, at the time of re-registration, that the permissible allocation of the investment to foreign investors has been filled.
Substantial limitations may exist in certain Middle Eastern countries with respect to an Underlying Fund’s ability to repatriate investment income or capital gains. An Underlying Fund could be adversely affected by delays in, or a refusal to grant, any required governmental approval for repatriation of capital, as well as by the application to the Underlying Fund of any restrictions on investment.
 
Certain Middle Eastern countries may be heavily dependent upon international trade and, consequently, have been and may continue to be negatively affected by trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which they trade. These countries also have been and may continue to be adversely impacted by economic conditions in the countries with which they trade. In addition, certain issuers located in Middle Eastern countries in which an Underlying Fund invests may operate in, or have dealings with, countries subject to sanctions and/or embargoes imposed by the U.S. government and the United Nations, and/or countries identified by the U.S. government as state sponsors of terrorism. As a result, an issuer may sustain damage to its reputation if it is identified as an issuer which operates in, or has dealings with, such countries. An Underlying Fund, as an investor in such issuers, will be indirectly subject to those risks.
 
Certain Middle Eastern countries have strained relations with other Middle Eastern countries due to territorial disputes, historical animosities or defense concerns, which may adversely affect the economies of these Middle Eastern countries. Certain Middle Eastern countries experience significant unemployment, as well as widespread underemployment. Recently, many Middle Eastern countries have experienced political, economic and social unrest as protestors have called for widespread reform. These protests may adversely affect the economies of these Middle Eastern countries.
 
Risk of Investing in the United States. The Fund has significant exposure to United States issuers. Decreasing imports or exports, changes in trade regulations and/or an economic recession in the United States may have a material adverse effect on the U.S. economy and the securities listed on U.S. exchanges. The financial crisis that began in 2007 caused a significant
 
20

decline in the value and liquidity of issuers in the United States. Policy and legislative changes in the United States are changing many aspects of financial and other regulation and may have a significant effect on the U.S. markets generally, as well as the value of certain securities. In addition, a continued rise in the U.S. public debt level or U.S. austerity measures may adversely affect U.S. economic growth and the securities to which the Fund has exposure.
 
Risk of Investing in the Basic Materials Industry Group. Issuers in the basic materials industry group could be adversely affected by commodity price volatility, exchange rates, import controls and increased competition. Companies in the basic materials industry group may be subject to swift fluctuations in supply and demand. Fluctuations may be caused by events relating to political and economic developments, the environmental impact of basic materials operations, and the success of exploration projects. Production of industrial materials often exceeds demand as a result of over-building or economic downturns, leading to poor investment returns. Issuers in the basic materials industry group are at risk for environmental damage and product liability claims and may be adversely affected by depletion of resources, delays in technical progress, labor relations, tax and government regulations related to changes to, among other things, energy and environmental policies.
Risk of Investing in the Capital Goods Industry Group. The capital goods industry group may be affected by fluctuations in the business cycle and by other factors affecting manufacturing demands. The capital goods industry group depends heavily on corporate spending. The capital goods industry group may perform well during times of economic expansion, and as economic conditions worsen, the demand for capital goods may decrease due to weakening demand, worsening business cash flows, tighter credit controls and deteriorating profitability. During times of economic volatility, corporate spending may fall and adversely affect the capital goods industry group. This industry group may also be affected by changes in interest rates, corporate tax rates and other government policies. Many capital goods are sold internationally and such companies are subject to market conditions in other countries and regions.
Risk of Investing in the Consumer Discretionary Sector. Companies engaged in the design, production or distribution of products or services for the consumer discretionary sector (including, without limitation, television and radio broadcasting, manufacturing, publishing, recording and musical instruments, motion pictures, photography, amusement and theme parks, gaming casinos, sporting goods and sports arenas, camping and recreational equipment, toys and games, apparel, travel-related services, automobiles, hotels and motels, and fast food and other restaurants) are subject to the risk that their products or services may become obsolete quickly. The success of these companies can depend heavily on disposable household income and consumer spending. During periods of an expanding economy, the consumer discretionary sector may outperform the consumer staples sector, but may underperform when economic conditions worsen. Moreover, the consumer discretionary sector can be significantly affected by several factors, including, without limitation, the performance of domestic and international economies, exchange rates, changing consumer preferences, demographics, marketing campaigns, cyclical revenue generation, consumer confidence, commodity price volatility, labor relations, interest rates, import and export controls, intense competition, technological developments and government regulation.
Risk of Investing in the Consumer Goods Industry. The success of the consumer goods industry is tied closely to the performance of the domestic and international economy, interest rates, exchange rates, competition, consumer confidence and consumer disposable income. The consumer goods industry may be strongly affected by trends, marketing campaigns and other factors affecting consumer demand. Governmental regulation affecting the use of various food additives may affect the profitability of certain companies in the consumer goods industry. Moreover, international events may affect food and beverage companies that derive a substantial portion of their net income from foreign countries. In addition, tobacco companies may be adversely affected by new laws, regulations and litigation. Many consumer goods may be marketed globally, and consumer goods companies may be affected by the demand and market conditions in other countries and regions. Companies in the consumer goods industry may be subject to severe competition, which may also have an adverse impact on their profitability. Changes in demographics and consumer preferences may affect the success of consumer products.
Risk of Investing in the Consumer Services Industry. The success of consumer product manufacturers and retailers (including food and drug retailers, general retailers, media, and travel and leisure) is tied closely to the performance of the domestic and international economy, interest rates, exchange rates, competition and consumer confidence. The consumer services industry depends heavily on disposable household income and consumer spending. Companies in the consumer services industry may be subject to severe competition, which may also have an adverse impact on their profitability. Changes in demographics and consumer preferences may affect the success of consumer service providers.

Risk of Investing in the Consumer Staples Sector. Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. Companies in the consumer staples sector may also be affected by changes in global economic, environmental and political events, economic conditions, the depletion of resources, and government regulation. For instance, government regulations may affect the permissibility of using various food additives and production methods of companies that make food products, which could affect company profitability. In addition, tobacco companies may be adversely affected by the adoption of proposed legislation and/or by litigation. Companies in the consumer staples sector also may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The prices of raw materials fluctuate in response to a number of factors, including, without limitation, changes in government agricultural support programs, exchange rates, import and export controls, changes in international agricultural and trading policies, and seasonal and weather conditions. Companies in the consumer staples sector may be subject to severe competition, which may also have an adverse impact on their profitability.
Risk of Investing in the Energy Sector. Companies in the energy sector are strongly affected by the levels and volatility of global energy prices, energy supply and demand, government regulations and policies, energy production and conservation efforts, technological change, and other factors that a company 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.
Companies in the energy sector may be adversely affected by terrorism, natural disasters or other catastrophes. Companies in the energy sector are at risk of civil liability from accidents resulting in injury, loss of life or property, pollution or other environmental damage claims. Disruptions in the oil industry or shifts in fuel consumption may significantly impact companies in this sector. Significant oil and gas deposits are located in emerging markets countries where corruption and security may raise significant risks, in addition to the other risks of investing in emerging markets. Additionally, the Middle East, where many companies in the energy sector may operate, has historically and recently seen widespread social unrest.
 
Companies in the energy sector may also be adversely affected by changes in exchange rates, interest rates, economic conditions, tax treatment, government regulation and intervention, negative perception, efforts at energy conservation and world events in the regions in which the companies operate (e.g., expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and repatriation of capital, military coups, social unrest, violence or labor unrest). Because a significant portion of revenues of companies in this sector is derived from a relatively small number of customers that are largely composed of governmental entities and utilities, governmental budget constraints may have a significant impact on the stock prices of companies in this sector. The energy sector is highly regulated. Entities operating in the energy sector are subject to significant regulation of nearly every aspect of their operations by federal, state and local governmental agencies. Such regulation can change rapidly or over time in both scope and intensity. Stricter laws, regulations or enforcement policies could be enacted in the future which would likely increase compliance costs and may materially adversely affect the financial performance of companies in the energy sector.
 
Risk of Investing in the Financials Sector. Companies in the financials sector include regional and money center banks, securities brokerage firms, asset management companies, savings banks and thrift institutions, specialty finance companies (e.g., credit card, mortgage providers), insurance and insurance brokerage firms, financial conglomerates and foreign banking and financial companies. The global financial markets have experienced very difficult conditions and volatility as well as significant adverse trends. The conditions in these markets have resulted in a decrease in availability of corporate credit, capital and liquidity and have led indirectly to the insolvency, closure or acquisition of a number of financial institutions. These conditions have also contributed to consolidation within the financial industry. In addition, the global financial industry has been materially and adversely affected by a significant decline in the value of mortgage-backed and asset-backed securities, and by the sovereign debt crisis. The prospects of many financial companies are questionable and continue to evolve as financial companies revise their outlooks and write down assets that they hold.
Most financial companies are subject to extensive governmental regulation, which limits their activities and may affect their ability to earn a profit from a given line of business. Government regulation may change frequently and may have significant adverse consequences for companies in the financials sector, including effects not intended by the regulation. Direct governmental intervention in the operations of financial companies and financial markets may materially and adversely affect
22


Table of Contents
the companies in which an Underlying Fund invests, including legislation in many countries that may increase government regulation, repatriation and other intervention. The impact of governmental intervention and legislative changes on any individual financial company or on the financials sector as a whole cannot be predicted. The valuation of financial companies has been and continues to be subject to unprecedented volatility and may be influenced by unpredictable factors, including interest rate risk and sovereign debt default. Certain financial businesses are subject to intense competitive pressures, including market share and price competition. Financial companies in foreign countries are subject to market specific and general regulatory and interest rate concerns. In particular, government regulation in certain foreign countries may include taxes and controls on interest rates, credit availability, minimum capital requirements, ban on short sales, prices and currency transfers.
The profitability of banks, savings and loan associations and financial companies is largely dependent on the availability and cost of capital funds and can fluctuate significantly when interest rates change; for instance, when interest rates go up, the value of securities issued by many types of companies in the financials sector generally goes down. In other words, financial companies may be adversely affected in certain market cycles, including, without limitation, during periods of rising interest rates, which may restrict the availability and increase the cost of capital, and during periods of declining economic conditions, which may cause, among other things, credit losses due to financial difficulties of borrowers.
 
In addition, general economic conditions are important to the operations of these companies, and financial difficulties of borrowers may have an adverse effect on the profitability of financial companies. Financial companies can be highly dependent upon access to capital markets and any impediments to such access, such as adverse overall economic conditions or a negative perception in the capital markets of a financial company’s financial condition or prospects, could adversely affect its business. Deterioration of credit markets, as experienced in 2008 and 2009, can have an adverse impact on a broad range of financial markets, causing certain financial companies to incur large losses. In these conditions, companies in the financials sector may experience significant declines in the valuation of their assets, take actions to raise capital and even cease operations. Some financial companies may also be required to accept or borrow significant amounts of capital from government sources and may face future government-imposed restrictions on their businesses or increased government intervention. In addition, there is no guarantee that governments will provide any such relief in the future. These actions may cause the securities of many companies in the financials sector to decline in value.
 
Risk of Investing in the Healthcare Sector. Companies in the healthcare sector are often issuers whose profitability may be affected by extensive government regulation, restrictions on government reimbursement for medical expenses, rising or falling costs of medical products and services, pricing pressure, an increased emphasis on outpatient services, limited number of products, industry innovation, changes in technologies and other market developments. Many healthcare companies are heavily dependent on patent protection and the actual or perceived safety and efficiency of their products.
Patents have a limited duration and, upon expiration, other companies may market substantially similar “generic” products that are typically sold at a lower price than the patented product, causing the original developer of the product to lose market share and/or reduce the price charged for the product, resulting in lower profits for the original developer. As a result, the expiration of patents may adversely affect the profitability of these companies.
In addition, because the products and services of many companies in the healthcare sector affect the health and well-being of many individuals, these companies are especially susceptible to extensive litigation based on product liability and similar claims. Healthcare companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the healthcare sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly, resulting in increased development costs, delayed cost recovery and loss of competitive advantage to the extent that rival companies have developed competing products or procedures, adversely affecting the company’s revenues and profitability. In other words, delays in the regulatory approval process may diminish the opportunity for a company to profit from a new product or to bring a new product to market, which could have a material adverse effect on a company’s business. Healthcare companies may also be strongly affected by scientific biotechnology or technological developments and their products may quickly become obsolete. Also, many healthcare companies offer products and services that are subject to governmental regulation and may be adversely affected by changes in governmental policies or laws. Legislation introduced or considered by certain governments on any individual healthcare company or on the healthcare sector as a whole cannot be predicted. These laws and proposals span a wide range of topics, including cost control, national health insurance, incentives for compensation in the provision of healthcare services, tax incentives and penalties related to healthcare insurance premiums, and promotion of prepaid healthcare plans. No one can

predict what proposals will be enacted or what potentially adverse effect they may have on healthcare-related or biotechnology-related companies.
Additionally, the expansion of facilities by healthcare related providers is subject to “determinations of need” by certain government authorities. This process not only increases the time and costs involved in these expansions, but also makes expansion plans uncertain, limiting the revenue and profitability growth potential of healthcare related facilities operators and negatively affecting the prices of their securities. Moreover, in recent years both local and national governmental budgets have come under pressure to reduce spending and control healthcare costs, which could both adversely affect regulatory processes and public funding available for healthcare products, services and facilities.
Risk of Investing in the Industrials Sector. The value of securities issued by companies in the industrials sector may be affected by supply and demand both for their specific products or services and for industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events and economic conditions affect the performance of companies in the industrials sector. The industrials sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors. For example, commodity price declines and unit volume reductions resulting from an over-supply of materials used in the industrials sector can adversely affect the sector. Furthermore, companies in the industrials sector may be subject to liability for environmental damage, product liability claims, depletion of resources, and mandated expenditures for safety and pollution control.
Risk of Investing in the Information Technology Sector. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face product obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Finally, while all companies may be susceptible to network security breaches, certain companies in the information technology sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses. These risks are heightened for information technology companies in foreign markets.
Risk of Investing in the Materials Sector. Companies in the materials sector may be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical progress, labor relations and government regulations, and mandated expenditures for safety and pollution control, among other factors. Also, companies in the materials sector are at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns. These risks are heightened for companies in the materials sector located in foreign markets.
 
Risk of Investing in the Oil and Gas Industry. Companies in the oil and gas industry are strongly affected by the levels and volatility of global energy prices, oil and gas supply and demand, government regulations and policies, oil and gas production and conservation efforts and technological change. The oil and gas industry is cyclical and from time to time may experience a shortage of drilling rigs, equipment, supplies or qualified personnel, or due to significant demand such services may not be available on commercially reasonable terms. Prices and supplies of oil and gas may fluctuate significantly over short and long periods of time due to national and international political changes, OPEC policies, changes in relationships among OPEC members and between OPEC and oil-importing nations, the regulatory environment, taxation policies, and the economies of key energy-consuming countries. Disruptions in the oil sub-industry or shifts in energy consumption may significantly impact companies in this industry. For instance, significant oil and gas deposits are located in emerging markets countries where corruption and security may raise significant risks, in addition to the other risks of investing in emerging markets. In addition, the Middle East, where many companies in the oil and gas industry may operate, has recently seen widespread social unrest. Oil and gas companies operate in a highly competitive industry, with intense price competition. A significant portion of their revenues may depend on a relatively small number of customers, including governmental entities and utilities. Companies that own or operate gas pipelines are subject to certain risks, including pipeline and equipment leaks and ruptures, explosions, fires, unscheduled downtime, transportation interruptions, discharges or releases of toxic or hazardous gases and other environmental risks.

Risk of Investing in the Technology Sector. Technology companies are characterized by periodic new product introductions, innovations and evolving industry standards, and, as a result, face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Companies in the technology sector are often smaller and less experienced companies and may be subject to greater risks than larger companies; these risks may be heightened for technology companies in foreign markets. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face product obsolescence due to rapid technological developments and frequent new product introduction, changes in consumer and business purchasing patterns, unpredictable changes in growth rates and competition for the services of qualified personnel. In addition, a rising interest rate environment tends to negatively affect companies in the technology sector because, in such an environment, those companies with high market valuations may appear less attractive to investors, which may cause sharp decreases in the companies’ market prices. Companies in the technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. The technology sector may also be adversely affected by changes or trends in commodity prices, which may be influenced or characterized by unpredictable factors. Finally, while all companies may be susceptible to network security breaches, certain companies in the technology sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.
Risk of Investing in the Telecommunications Sector. The telecommunications sector of an economy is often subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new regulatory requirements may negatively affect the business of telecommunications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. Companies in the telecommunications sector may experience distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology. Technological innovations may make the products and services of certain telecommunications companies obsolete. Finally, while all companies may be susceptible to network security breaches, certain companies in the telecommunications sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.
Risk of Investing in the Utilities Sector. Investments in utility companies involve special considerations, including the risk of changing commodity prices, government regulation stipulating rates charged by utilities, increased tariffs, changes in tax laws, interest rate fluctuations and changes in the cost of providing specific utility services. The utilities industry is also subject to potential terrorist attacks, natural disasters and severe weather conditions, as well as regulatory and operational burdens associated with the operation and maintenance of nuclear facilities. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. In certain countries, regulatory authorities may also restrict a company’s access to new markets, thereby diminishing the company’s long-term prospects.
There are substantial differences among the regulatory practices and policies of various jurisdictions, and any regulatory agency may make major shifts in policy from time to time. There is no assurance that regulatory authorities will, in the future, grant rate increases or that such increases will be adequate to permit the payment of dividends on common stocks issued by a utility company. Additionally, existing and possible future regulatory legislation may make it even more difficult for utilities to obtain adequate relief. Certain of the issuers of securities held in an Underlying Fund's portfolio may own or operate nuclear generating facilities. Governmental authorities may from time to time review existing policies and impose additional requirements governing the licensing, construction and operation of nuclear power plants. Prolonged changes in climate conditions can also have a significant impact on both the revenues of an electric and gas utility as well as the expenses of a utility, particularly a hydro-based electric utility.
The rates that traditional regulated utility companies may charge their customers generally are subject to review and limitation by governmental regulatory commissions. Rate changes may occur only after a prolonged approval period or may not occur at all, which could adversely affect earnings and dividends when costs are rising. The value of regulated utility debt securities (and, to a lesser extent, equity securities) tends to have an inverse relationship to the movement of interest rates. Certain utility companies have experienced full or partial deregulation in recent years. These utility companies are frequently more similar to industrial companies in that they are subject to greater competition and have been permitted by regulators to diversify outside of their original geographic regions and their traditional lines of business. As a result, some companies may be forced to defend their core business and may be less profitable.

Proxy Voting Policy
The Trust has adopted proxy voting policies for the Fund that incorporate and amplify the proxy voting guidelines of BFA, the investment adviser to the Fund. The Trust has delegated to BFA the responsibility for voting proxies on the portfolio securities held by the Fund. The remainder of this section discusses the Fund’s proxy voting guidelines and BFA’s role in implementing such guidelines.
BFA votes (or refrains from voting) proxies for the Fund in a manner that BFA, in the exercise of its independent business judgment, concludes is in the best economic interests of the Fund. In some cases, BFA may determine that it is in the best economic interests of the Fund to refrain from exercising the Fund’s proxy voting rights (such as, for example, proxies on certain non-U.S. securities that might impose costly or time-consuming in-person voting requirements). With regard to the relationship between securities lending and proxy voting, BFA’s approach is also driven by the Fund's 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 the likely economic value of casting a vote generally 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 BFA recalling loaned securities in order to ensure they are voted. Periodically, BFA 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 are necessary in light of any regulatory changes. BFA will normally vote on specific proxy issues in accordance with its proxy voting guidelines. BFA’s proxy voting guidelines provide detailed guidance as to how to vote proxies on certain important or commonly raised issues. BFA may, in the exercise of its business judgment, conclude that the proxy voting guidelines do not cover the specific matter upon which a proxy vote is requested, or that an exception to the proxy voting guidelines would be in the best economic interests of the Fund. BFA votes (or refrains from voting) proxies without regard to the relationship of the issuer of the proxy (or any shareholder of such issuer) to the Fund, the Fund’s affiliates (if any), BFA or BFA’s affiliates, or the Distributor or the Distributor’s affiliates. When voting proxies, BFA attempts to encourage issuers to follow practices that enhance shareholder value and increase transparency and allow the market to place a proper value on their assets. With respect to certain specific issues:
The Fund generally supports the board’s nominees in the election of directors and generally supports proposals that strengthen the independence of boards of directors;
 
When a director has committed himself or herself to service on more than four public company boards (but no more than six public company boards in most circumstances), the Fund will consider such director’s individual circumstances in determining whether the director will be able to commit sufficient focus and time to a particular company;
 
The Fund generally defers to an issuer’s choice of auditors so long as the corporate auditors represent the interests of shareholders and provide an independent view of the propriety of financial reporting decisions of management;
The Fund generally favors disclosure of a company’s compensation and benefits policies and opposes excessive compensation, but believes that compensation matters are normally best determined by a company’s board of directors;
The Fund generally expects to support capital structure requests that it believes enhance the rights of common shareholders and oppose requests that appear to be unreasonably dilutive;
The Fund generally does not support proposals on social issues that lack a demonstrable economic benefit to the issuer and the Fund investing in such issuer; and
The Fund generally votes against anti-takeover proposals and proposals that would create additional barriers or costs to corporate transactions that are likely to deliver a premium to shareholders.
BFA maintains institutional policies and procedures that are designed to prevent any relationship between the issuer of the proxy (or any shareholder of the issuer) and the Fund, the Fund’s affiliates (if any), BFA or BFA’s affiliates (if any) or the Distributor or the Distributor’s affiliates, from having undue influence on BFA’s proxy voting activity. In certain instances, BFA may determine to engage an independent fiduciary to vote proxies as a further safeguard against potential conflicts of interest or as otherwise required by applicable law. The independent fiduciary may either vote such proxies or provide BFA with instructions as to how to vote such proxies. In the latter case, BFA votes the proxy in accordance with the independent fiduciary’s determination.

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 BFA, the Distributor and their affiliates, and the administrator, custodian and fund accountant who deal directly with or assist in, functions related to investment management, distribution, administration, custody, securities lending and fund accounting, as may be necessary to conduct business in the ordinary course in a manner consistent with agreements with the Fund and the terms of the Fund's current registration statement. In addition, the Fund discloses its portfolio holdings and the percentages they represent of the Fund's net assets at least monthly, and as often as 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 after the end of each fiscal quarter and will provide that information to shareholders as required by federal securities laws and regulations thereunder. The Fund may, however, voluntarily disclose all or part of its portfolio holdings other than in connection with the creation/redemption process, as discussed above, in advance of required filings with the SEC, provided that such information is made generally available to all shareholders and other interested parties in a manner that is consistent with the above policy for disclosure of portfolio holdings information. Such information may be made available through a publicly-available website or other means that make the information available to all likely interested parties contemporaneously.

Construction and Maintenance of the Underlying Index
A description of the Underlying Index is provided below.
The Morningstar U.S. Bond Market Yield-Optimized Index
 
The Morningstar U.S. Bond Market Yield-Optimized Index is broadly diversified within the fixed income asset class and seeks to deliver current income. The Underlying Index consists exclusively of U.S.-listed ETFs that collectively target fixed-income asset class sectors in allocation weights with certain upper limit weights set at a sector level. As of February 25, 2014, the Underlying Index consisted of 13 constituent ETFs.
 
Index Construction. The Underlying Index is governed by transparent, objective rules for security election, exclusion, rebalancing, and adjustments for corporate actions; all of which are described in the Morningstar U.S. Bond Market Yield-Optimized Index Rulebook (the “Index Rulebook”). Morningstar, Inc. (“Morningstar”) makes no subjective determinations related to index composition.
To be eligible for inclusion in the Underlying Index, an ETF must track a benchmark that is broadly representative of the asset class and be registered as an investment company under the 1940 Act. It must trade on a U.S. exchange, have at least one year of trading history, a history of dividend payments, a three-month average daily trading volume greater than 25,000 shares, and meet certain asset minimums as elaborated in the Index Rulebook. The goal of the Underlying Index is to represent an allocation strategy to distinct fixed income sectors of no greater than 50% government related, no greater than 50% securitized, no more than 50% investment-grade credit and no more than 20% non-investment-grade credit, which consists of Underlying Funds that, in aggregate, the index provider, Morningstar, considers to exhibit high risk adjusted yield characteristics. Each fixed income sector has its own risk profile.
Ineligible ETFs include those that had more than 10 non-trading days in the prior quarter, those that invest in securities of a single country, sector or industry, or in commodities, managed futures, municipal bonds, or inflation linked strategies, other allocated funds (ETF fund of funds), bank loan funds, convertible bond funds and Master Limited Partnerships and any other exclusions, as defined in the Index Rulebook. Once Morningstar has identified the investable universe, a proprietary model with an explicit preference for risk adjusted yield developed by Morningstar Investment Management is applied to identify index constituents, which are then further subject to liquidity and minimum asset screens. A fixed asset allocation and capping is then applied.
Issue Changes. Securities are added or deleted from each index, on a quarterly basis, based on rules outlined for security selection, exclusion, rebalancing, and adjustments for corporate actions as set forth in the Index Rulebook.
Scheduled Reconstitution Dates. The Index is reconstituted – i.e., the Index membership is reset – quarterly. Adjustments are made on the last business day of the month in February, May, August, and November. The changes become effective on the next business day.
Scheduled Rebalancing Dates. The index is rebalanced – i.e., the target allocation percentage of each constituent ETF is adjusted – quarterly. Adjustments are made at the close of trade on the last business day in February, May, August, and November. The changes become effective on the next business day. Market data used for rebalancing is from the 10th business day of rebalance month.
Index Availability. Morningstar Indexes are calculated continuously and are available from major data vendors.

Investment Restrictions
The Fund has adopted its investment objective as a non-fundamental investment policy. Therefore, the Fund may change its investment objective and its Underlying Index without shareholder approval. The Board has adopted restrictions and policies relating to the investment of the Fund’s assets and its activities. Certain of the restrictions are fundamental policies of the Fund and may not be changed without the approval of the holders of a majority of the Fund’s outstanding voting securities (which, for this purpose and under the Investment Company Act, means the lesser of (i) 67% or more of the shares represented at a meeting at which more than 50% of the outstanding shares are represented or (ii) more than 50% of the outstanding shares).
Under these fundamental investment restrictions, the Fund may not:
1. Concentrate its investments in a particular industry, as that term is used in the Investment Company Act, except that the Fund will concentrate to approximately the same extent that its Underlying Index concentrates in the securities of a particular industry or group of industries.
2. Borrow money, except as permitted under the Investment Company Act.
3. Issue senior securities to the extent such issuance would violate the Investment Company Act.
4. Purchase or hold real estate, except the Fund may purchase and hold securities or other instruments that are secured by, or linked to, real estate or interests therein, securities of real estate investment trusts, mortgage-related securities and securities of issuers engaged in the real estate business, and the Fund may purchase and hold real estate as a result of the ownership of securities or other instruments.
5. Underwrite securities issued by others, except to the extent that the sale of portfolio securities by the Fund may be deemed to be an underwriting or as otherwise permitted by applicable law.
6. Purchase or sell commodities or commodity contracts, except as permitted by the Investment Company Act.
7. Make loans to the extent prohibited by the Investment Company Act.
8. Make any investment inconsistent with the Fund's classification as a diversified company under the Investment Company Act.
Notations Regarding the Fund’s Fundamental Investment Restrictions
The following notations are not considered to be part of the Fund’s fundamental investment restrictions and are subject to change without shareholder approval.
With respect to the fundamental policy relating to concentration set forth in (1) above, the Investment Company Act does not define what constitutes “concentration” in an industry. The Commission staff has taken the position that investment of 25% or more of a fund’s total assets in one or more issuers conducting their principal activities in the same industry or group of industries constitutes concentration. It is possible that interpretations of concentration could change in the future. The policy in (1) above will be interpreted to refer to concentration as that term may be interpreted from time to time. The policy also will be interpreted to permit investment without limit in the following: securities of the U.S. government and its agencies or instrumentalities; securities of state, territory, possession or municipal governments and their authorities, agencies, instrumentalities or political subdivisions; and repurchase agreements collateralized by any such obligations. Accordingly, issuers of the foregoing securities will not be considered to be members of any industry. There also will be no limit on investment in issuers domiciled in a single jurisdiction or country. Finance companies will be considered to be in the industries of their parents if their activities are primarily related to financing the activities of the parents. Each foreign government will be considered to be a member of a separate industry. With respect to the Fund’s industry classifications, the Fund currently utilizes any one or more of the industry sub-classifications used by one or more widely recognized market indexes or rating group indexes, and/or as defined by Fund management. The policy also will be interpreted to give broad authority to the Fund as to how to classify issuers within or among industries.
With respect to the fundamental policy relating to borrowing money set forth in (2) above, the Investment Company Act permits the Fund to borrow money in amounts of up to one-third of the Fund’s total assets from banks for any purpose, and to borrow up to 5% of the Fund’s total assets from banks or other lenders for temporary purposes. (The Fund’s total assets include the amounts being borrowed.) To limit the risks attendant to borrowing, the Investment Company Act requires the Fund to maintain at all times an “asset coverage” of at least 300% of the amount of its borrowings. Asset coverage means the ratio that the value of the Fund’s total assets (including amounts borrowed), minus liabilities other than borrowings,
29


Table of Contents
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 Commission 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 Commission). 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 Securities 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 Securities 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, Commission 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.
The Fund is currently classified as a diversified fund under the Investment Company Act. This means that the Fund may not purchase securities of an issuer (other than obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities) if, with respect to 75% of its total assets, (a) more than 5% of the Fund’s total assets would be invested in securities of that issuer or (b) the Fund would hold more than 10% of the outstanding voting securities of that issuer. With respect to the remaining 25% of its total assets, the Fund can invest more than 5% of its assets in one issuer. Under the Investment Company Act, the Fund cannot change its classification from diversified to non-diversified without shareholder approval.
Under its non-fundamental investment restrictions, which may be changed by the Board without shareholder approval, the Fund may not:
Make short sales of securities or maintain a short position, except to the extent permitted by the Fund’s Prospectus and Statement of Additional Information, as amended from time to time, and applicable law.
Unless otherwise indicated, all limitations under the Fund’s fundamental or non-fundamental investment restrictions apply only at the time that a transaction is undertaken. Any change in the percentage of the Fund’s assets invested in certain securities or other instruments resulting from market fluctuations or other changes in the Fund’s total assets will not require the Fund to dispose of an investment until the Adviser determines that it is practicable to sell or close out the investment without undue market or tax consequences.
 
The Fund has adopted a non-fundamental investment policy in accordance with Rule 35d-1 under the 1940 Act to invest, under normal circumstances, at least 80% of the value of its net assets, plus the amount of any borrowings for investment purposes, in securities in the Fund's Underlying Index. The Fund also has adopted a policy to provide its shareholders with at
 
30


Table of Contents
least 60 days' prior written notice of any change in such policy. If, subsequent to an investment, the 80% requirement is no longer met, the Fund's future investments will be made in a manner that will bring the Fund into compliance with this policy.
The Fund has adopted a non-fundamental limitation such that, under normal market conditions, any borrowings by the Fund will not exceed 10% of the Fund's net assets.
Although the SEC has granted an exemptive order to the Trust permitting registered investment companies and unit investment trusts that enter into a participation agreement with the Trust (“Investing Funds”) to invest in iShares Funds beyond the limits set forth in Section 12(d)(1) of the 1940 Act subject to certain terms and conditions, the exemptive order is not applicable to the Fund. Accordingly, Investing Funds must adhere to the limits set forth in Section 12(d)(1) of the 1940 Act when investing in the Fund.
Continuous Offering
The method by which Creation Units are created and traded may raise certain issues under applicable securities laws. Because new Creation Units are issued and sold by the Fund on an ongoing basis, at any point a “distribution,” as such term is used in the 1933 Act, may occur. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject them to the prospectus delivery requirement and liability provisions of the 1933 Act.
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 is satisfied by the fact that the prospectus is available at the Listing Exchange upon request. The prospectus delivery mechanism provided in Rule 153 is available only with respect to transactions on an exchange.
Management
 
Trustees and Officers. The Board has responsibility for the overall management and operations of the Fund, including general supervision of the duties performed by BFA and other service providers. Each Trustee serves until he or she resigns, is removed, dies, retires or becomes incapacitated. The President, Chief Compliance Officer, Treasurer and Secretary shall each hold office until their successors are chosen and qualify, and all other officers shall hold office until he or she resigns or is removed. Trustees who are not “interested persons” (as defined in the 1940 Act) of the Trust are referred to as independent trustees (“Independent Trustees”).
The registered investment companies advised by BFA or its affiliates are organized into one complex of closed-end funds, two complexes of open-end funds and one complex of exchange-traded funds (“Exchange-Traded Fund Complex”) (each, a “BlackRock Fund Complex”). The Fund is included in the BlackRock Fund Complex referred to as the Exchange-Traded Fund Complex. Each Trustee also serves as a Director of iShares, Inc., a Director of iShares MSCI Russia Capped ETF, Inc. and a Trustee of iShares U.S. ETF Trust and, as a result, oversees a total of 310 funds within the Exchange-Traded Fund Complex. With the exception of Robert S. Kapito, Mark Wiedman and Warren Collier, the address of each Trustee and officer is c/o BlackRock, Inc., 400 Howard Street, San Francisco, CA 94105. The address of Mr. Kapito, Mr. Wiedman and Mr. Collier is c/o BlackRock, Inc., Park Avenue Plaza, 55 East 52nd Street, New York, NY 10055. The Board has designated Robert H. Silver as its

The Board has concluded that, based on each Trustee’s experience, qualifications, attributes or skills on an individual basis and in combination with those of the other Trustees, each Trustee should serve as a Trustee of the Board. Among the attributes common to all Trustees are their ability to review critically, evaluate, question and discuss information provided to them, to interact effectively with the Fund's investment adviser, other service providers, counsel and the independent registered public accounting firm, and to exercise effective business judgment in the performance of their duties as Trustees. A Trustee’s ability to perform his or her duties effectively may have been attained through the Trustee’s educational background or professional training; business, consulting, public service or academic positions; experience from service as a Board member of the Fund and the other funds in the Trust (and any predecessor funds), other investment funds, public companies, or non-profit entities or other organizations; and/or other life experiences. Also, set forth below is a brief discussion of the specific experience, qualifications, attributes or skills of each Trustee that led the Board to conclude that he or she should serve as a Trustee.

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 nine members, seven of whom are Independent Trustees. The Board currently conducts regular meetings five 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 Chairman. The Chairman’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 Chairman may also perform such other functions as may be delegated by the Board from time to time. The Board has established six standing Committees: a Nominating and Governance Committee, an Audit Committee, a 15(c) Committee, a Securities Lending 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 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 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, 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 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. 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. The Independent Trustees have engaged independent legal counsel to assist them in performing their oversight responsibilities.
 
Committees of the Board of Trustees. Each Independent Trustee serves on the Audit Committee. The Chair of the Audit Committee is Charles A. Hurty. The purposes of the Audit Committee are to assist the Board (i) in its oversight of the Trust's accounting and financial reporting principles and policies and related controls and procedures maintained by or on behalf of the Trust; (ii) in its oversight of the Trust's financial statements and the independent audit thereof; (iii) in selecting, evaluating and, where deemed appropriate, replacing the independent accountants (or nominating the independent accountants to be proposed for shareholder approval in any proxy statement); (iv) in evaluating the independence of the independent accountants; (v) in complying with legal and regulatory requirements that relate to the Trust's accounting and financial reporting, internal controls, compliance controls and independent audits; and (vi) to assume such other responsibilities as may be delegated by the Board. The Audit Committee met four times during the fiscal year ended October 31, 2013.
 
The members of the Nominating and Governance Committee are Cecilia H. Herbert (Chair), Charles A. Hurty, Madhav V. Rajan and John E. Kerrigan, all of whom are Independent Trustees. The Nominating and Governance Committee nominates individuals for Independent Trustee membership on the Board. The Nominating and Governance Committee functions include, but are not limited to, the following: (i) reviewing the qualifications of any person properly identified or nominated to serve as an Independent Trustee; (ii) recommending to the Board and current Independent Trustees the nominee(s) for appointment as an Independent Trustee by the Board and current Independent Trustees and/or for election as Independent Trustees by shareholders to fill any vacancy for a position of Independent Trustee(s) on the Board; (iii) recommending to the

1 Appointed to serve as an Interested Trustee effective December 31, 2013.

Remuneration of Trustees. Each current Independent Trustee is paid an annual retainer of $300,000 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. For the period from January 1, 2013 through December 31, 2013, each current Independent Trustee was paid an annual retainer of $275,000 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.

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”) has a significant economic interest in BlackRock, Inc., the parent of BFA, the Fund's investment adviser. PNC is considered to be an affiliate of BlackRock, Inc., under the 1940 Act. Certain activities of BFA, BlackRock, Inc. and their affiliates (collectively, “BlackRock”) and PNC and its affiliates (collectively, “PNC” and together with BlackRock, “Affiliates”), with respect to the Fund and/or other accounts managed by BlackRock or PNC, may give rise to actual or perceived conflicts of interest such as those described below.
BlackRock is one of the world's largest asset management firms. PNC is a diversified financial services organization spanning the retail, business and corporate markets. BlackRock and PNC are affiliates of one another under the 1940 Act. BlackRock and PNC and their respective affiliates (including, for these purposes, their directors, partners, trustees, managing members, officers and employees), including the entities and personnel who may be involved in the investment activities and business operations of the Fund, are engaged worldwide in businesses, including equity, fixed-income, cash management and alternative investments. 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 activities and interests include potential multiple advisory, transactional, financial and other interests in securities and other instruments that may be purchased or sold by the Fund.
BlackRock and its Affiliates have proprietary interests in, and may manage or advise with respect to, accounts or funds (including separate accounts and other funds and collective investment vehicles) that have investment objectives similar to those of the Fund and/or that engage in transactions in the same types of securities, currencies and instruments as the
43


Table of Contents
Fund. One or more Affiliates are also major participants in the global currency, equities, swap and fixed-income markets, in each case both on a proprietary basis and for the accounts of customers. As such, one or more Affiliates are or may be actively engaged in transactions in the same securities, currencies, and instruments in which the Fund invests. Such activities could affect the prices and availability of the securities, currencies, and instruments in which the Fund invests, which could have an adverse impact on the Fund's performance. Such transactions, particularly in respect of most proprietary accounts or customer accounts, will be executed independently of the Fund's transactions and thus at prices or rates that may be more or less favorable than those obtained by the Fund. When BlackRock and its Affiliates purchase or sell the same assets for their managed accounts, including the Fund, the assets actually purchased or sold may be allocated among the accounts on a basis determined in their good faith discretion to be equitable. In some cases, this system may adversely affect the size or price of the assets purchased or sold for the Fund. In addition, transactions in investments by one or more other accounts managed by BlackRock or its Affiliates may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund, particularly, but not limited to, with respect to small capitalization, emerging market or less liquid strategies. This may occur when investment decisions regarding the Fund are based on research or other information that is also used to support decisions for other accounts. When BlackRock or its Affiliates 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 or its Affiliates may, in certain cases, elect to implement internal policies and procedures designed to limit such consequences, which may cause the Fund to be unable to engage in certain activities, including purchasing or disposing of securities, when it might otherwise be desirable for it to do so.
Conflicts may also arise because portfolio decisions regarding the Fund may benefit other accounts managed by BlackRock or its Affiliates. For example, the sale of a long position or establishment of a short position by the Fund may impair the price of the same security sold short by (and therefore benefit) one or more Affiliates or their other accounts, and the purchase of a security or covering of a short position in a security by the Fund may increase the price of the same security held by (and therefore benefit) one or more Affiliates or their other accounts.
 
In certain circumstances, BFA, on behalf of the Fund, may seek to buy from or sell securities to another fund or account advised by BFA or an affiliate. BFA may (but is not required to) effect purchases and sales between BFA clients or clients of affiliates (“cross trades”), including the Fund, if BFA 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 BFA’s decision to engage in these transactions for the Fund. BFA may have a potentially conflicting division of loyalties and responsibilities to the parties in such transactions. Where the Fund participates in a cross trade, BFA will comply with procedures adopted pursuant to Rule 17a-7 under the 1940 Act and applicable SEC guidance.
 
BlackRock and its Affiliates and their clients may pursue or enforce rights with respect to an issuer in which the Fund has invested, and those activities may have an adverse effect on the Fund. As a result, prices, availability, liquidity and terms of the Fund's investments may be negatively impacted by the activities of BlackRock or its Affiliates or their clients, and transactions for the Fund may be impaired or effected at prices or terms that may be less favorable than would otherwise have been the case.
The results of the Fund's investment activities may differ significantly from the results achieved by BlackRock and its Affiliates for their proprietary accounts or other accounts (including investment companies or collective investment vehicles) managed or advised by them. It is possible that one or more Affiliate-managed accounts and such other accounts will achieve investment results that are substantially more or less favorable than the results achieved by the Fund. Moreover, it is possible that the Fund will sustain losses during periods in which one or more Affiliate-managed accounts achieve significant profits on their trading for proprietary or other accounts. The opposite result is also possible. The investment activities of one or more Affiliates for their proprietary accounts and accounts under their management may also 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.
From time to time, the Fund's activities may also be restricted because of regulatory restrictions applicable to one or more Affiliates, and/or their internal policies designed to comply with such restrictions. As a result, there may be periods, for example, when BlackRock, and/or one or more Affiliates, will not initiate or recommend certain types of transactions in
44


Table of Contents
certain securities or instruments with respect to which BlackRock and/or one or more Affiliates are performing services or when position limits have been reached.
In connection with its management of the Fund, BlackRock may have access to certain fundamental analysis and proprietary technical models developed by one or more Affiliates. BlackRock will not be under any obligation, however, to effect transactions on behalf of the Fund in accordance with such analysis and models. In addition, neither BlackRock nor any of its Affiliates will have any obligation to make available any information regarding their proprietary activities or strategies, or the activities or strategies used for other accounts managed by them, for the benefit of the management of the Fund and it is not anticipated that BlackRock will have access to such information for the purpose of managing the Fund. The proprietary activities or portfolio strategies of BlackRock and its Affiliates, or the activities or strategies used for accounts managed by them or other customer accounts could conflict with the transactions and strategies employed by BlackRock in managing the Fund.
 
The Fund may be included in investment models developed by BFA and its affiliates for use by clients and financial advisors. The price, availability and liquidity of the Fund may be impacted by purchases and redemptions of the Fund by model-driven investment portfolios.
 
In addition, certain principals and certain employees of BlackRock are also principals or employees of Affiliates. As a result, the performance by these principals and employees of their obligations to such other entities 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 customers of BlackRock or its Affiliates, or, to the extent permitted by the SEC, BlackRock or another Affiliate, serves as the counterparty, principal or issuer. In such cases, such party's interests in the transaction will be adverse to the interests of the Fund, and such party may have no incentive to assure that the Fund obtains the best possible prices or terms in connection with the transactions. In addition, the purchase, holding and sale of such investments by the Fund may enhance the profitability of BlackRock or its Affiliates. One or more Affiliates may also create, write or issue derivatives for their customers, the underlying securities, currencies or instruments of which may be those in which the Fund invests or which may be based on the performance of the Fund. The Fund may, subject to applicable law, purchase investments that are the subject of an underwriting or other distribution by one or more Affiliates and may also enter into transactions with other clients of an Affiliate where such other clients have interests adverse to those of the Fund.
At times, these activities may cause departments of BlackRock or its Affiliates to give advice to clients that may cause these clients to take actions adverse to the interests of the Fund. To the extent affiliated transactions are permitted, the Fund will deal with BlackRock and its Affiliates on an arms-length basis. BlackRock or its Affiliates may also have an ownership interest in certain trading or information systems used by the Fund. The Fund's use of such trading or information systems may enhance the profitability of BlackRock and its Affiliates.
One or more Affiliates may act as broker, dealer, agent, lender or adviser or in other commercial capacities for the Fund. It is anticipated that the commissions, 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 an Affiliate will be in its view commercially reasonable, although each Affiliate, including its sales personnel, will have an interest in obtaining fees and other amounts that are favorable to the Affiliate and such sales personnel.
Subject to applicable law, the Affiliates (and their personnel and other distributors) will be entitled to retain fees and other amounts that they receive in connection with their service to the Fund as broker, dealer, agent, lender, adviser or in other commercial capacities and no accounting to the Fund or its shareholders will be required, and no fees or other compensation payable by the Fund or its shareholders will be reduced by reason of receipt by an Affiliate of any such fees or other amounts.
When an Affiliate acts as broker, dealer, agent, adviser or in other commercial capacities in relation to the Fund, the Affiliate may take commercial steps in its own interests, which may have an adverse effect on the Fund. The Fund will be required to establish business relationships with its counterparties based on the Fund's own credit standing. Neither BlackRock nor any of the Affiliates will have any obligation to allow their credit to be used in connection with the Fund's establishment of its business relationships, nor is it expected that the Fund's counterparties will rely on the credit of BlackRock or any of the Affiliates in evaluating the Fund's creditworthiness.

Lending on behalf of the Fund is done by BTC pursuant to SEC exemptive relief, enabling BTC to act as securities lending agent to, and receive a share of securities lending revenues from, the Fund. BFA may also receive compensation for managing the reinvestment of the cash collateral from securities lending. There is a potential conflict of interest in that BTC as a lending agent may have an incentive to increase the amount of securities on loan or to lend riskier assets in order to generate additional revenue for BTC and its affiliates. However, BTC’s SEC exemptive relief sets forth certain conditions designed to assist in mitigating such conflicts of interest.
Purchases and sales of securities for the Fund may be bunched or aggregated with orders for other BlackRock client accounts. BlackRock, however, is not required to bunch or aggregate orders if portfolio management decisions for different accounts are made separately, or if it determines 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.
BlackRock may select brokers (including, without limitation, Affiliates) that furnish BlackRock, the Fund, other BlackRock client accounts or other Affiliates or personnel, directly or through correspondent relationships, with research or other appropriate services which provide, in BlackRock's view, appropriate assistance to BlackRock in the investment decision-making process (including with respect to futures, fixed-price offerings and over-the-counter 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 may receive research that is bundled with the trade execution, clearing, and/or settlement services provided by a particular broker-dealer. To the extent that BlackRock receives research on this basis, many of the same conflicts related to traditional soft dollars may exist. For example, the research effectively will be paid by client commissions that also will be used to pay for the execution, clearing, and settlement services provided by the broker-dealer and will not be paid by BlackRock.
BlackRock may endeavor to execute trades through brokers who, pursuant to such arrangements, provide research or other services in order to ensure the continued receipt of research or other services BlackRock believes are useful in its investment decision-making process. BlackRock may from time to time choose not to engage in the above described arrangements to varying degrees. BlackRock may also enter into commission sharing arrangements under which BlackRock may execute transactions through a broker-dealer, including, where permitted, an Affiliate, and request that the broker-dealer allocate a portion of the commissions or commission credits to another firm that provides research to BlackRock. To the extent that BlackRock engages in commission sharing arrangements, many of the same conflicts related to traditional soft dollars may exist.
BlackRock may utilize certain electronic crossing networks (“ECNs”) 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 mark-ups/mark-downs, will generally be charged to clients and, like commissions and mark-ups/mark-downs, 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 its Affiliates, provided that BlackRock believes such voting decisions to be in accordance with its fiduciary obligations. For a more detailed discussion of these policies and procedures, see the Proxy Voting Policy section of this SAI.
It is also possible that, from time to time, BlackRock or its Affiliates may, although they are not required to, 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 its Affiliates reserve the right to sell or redeem 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 its Affiliates could significantly reduce the asset size of the Fund, which might have an adverse effect on the Fund's liquidity, investment flexibility, portfolio diversification and expense ratio. BlackRock will consider the effect of redemptions on the Fund and other shareholders in deciding whether to redeem its shares.
It is possible that the Fund may invest in securities of companies with which an Affiliate has or is trying to develop investment banking relationships as well as securities of entities in which BlackRock or its Affiliates has significant debt or equity investments or in which an Affiliate makes a market. The Fund also may invest in securities of companies to which an Affiliate provides or may someday provide research coverage. Such investments could cause conflicts between the interests of the Fund and the interests of other clients of BlackRock or its Affiliates. In making investment decisions for the Fund, BlackRock is not permitted to obtain or use material non-public information acquired by any division, department or Affiliate of BlackRock in the course of these activities. In addition, from time to time, the activities of an Affiliate may limit the Fund's flexibility in purchases and sales of securities. When an Affiliate is engaged in an underwriting or other distribution of securities of an entity, BlackRock may be prohibited from purchasing or recommending the purchase of certain securities of that entity for the Fund.
BlackRock and its Affiliates, their personnel and other financial service providers may have interests in promoting sales of the Fund. With respect to BlackRock and its Affiliates and their personnel, the remuneration and profitability relating to services to and sales of the Fund or other products may be greater than remuneration and profitability relating to services to and sales of certain funds or other products that might be provided or offered. BlackRock and its Affiliates and their sales personnel may directly or indirectly receive a portion of the fees and commissions charged to the Fund or its shareholders. BlackRock and its advisory or other personnel may also benefit from increased amounts of assets under management. Fees and commissions may also be higher than for other products or services, and the remuneration and profitability to BlackRock or its Affiliates and such personnel resulting from transactions on behalf of or management of the Fund may be greater than the remuneration and profitability resulting from other funds or products.
BlackRock and its Affiliates and their personnel may receive greater compensation or greater profit in connection with an account for which BlackRock serves as an adviser than with an account advised by an unaffiliated investment adviser. Differentials in compensation may be related to the fact that BlackRock may pay a portion of its advisory fee to its Affiliate, or relate to compensation arrangements, including for portfolio management, brokerage transactions or account servicing. Any differential in compensation may create a financial incentive on the part of BlackRock or its Affiliates and their personnel to recommend BlackRock over unaffiliated investment advisers or to effect transactions differently in one account over another.
Third parties, including service providers to BFA 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 BFA, and may provide an incentive to BFA to retain such third parties to provide services to the Fund.
BlackRock and its Affiliates may provide valuation assistance to certain clients with respect to certain securities or other investments and the valuation recommendations made for their clients' accounts may differ from the valuations for the same securities or investments assigned by the Fund's pricing vendors, especially if such valuations are based on broker-dealer quotes or other data sources unavailable to the Fund's pricing vendors. While BlackRock will generally communicate its valuation information or determinations to the Fund's pricing vendors and/or fund accountants, there may be instances
47


Table of Contents
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 valuations are not readily available or such valuations do not reflect current market values, the affected investments will be valued using fair value pricing, pursuant to procedures adopted by the Trust's Board. When determining an asset’s “fair value,” BlackRock seeks to determine the price that the Fund might reasonably expect to receive from the current sale of that asset in an arm’s-length transaction on the date on which the assets or liabilities are being valued, not on what 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. 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 a security. The fair value of one or more securities may not, in retrospect, be the price at which those assets 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 BlackRock receiving additional revenue.
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 in which it invests, which may result in the Fund bearing some additional expenses.
BlackRock and its Affiliates and their directors, officers and employees, may buy and sell securities or other investments for their own accounts, and may have conflicts of interest with respect to investments made on behalf of the Fund. As a result of differing trading and investment strategies or constraints, positions may be taken by directors, officers, employees and Affiliates of BlackRock 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 each has 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 can be reviewed and copied at the SEC's Public Reference Room in Washington, D.C. Information on the operation of the Public Reference Room may be obtained by calling the SEC at (202) 551-8090. Each code of ethics is also available on the EDGAR Database on the SEC's Internet site at http://www.sec.gov, and copies may be obtained, after paying a duplicating fee, by e-mail at publicinfo@sec.gov or by writing the SEC's Public Reference Section, Washington, DC 20549-1520.
BlackRock and its Affiliates will not purchase securities or other property from, or sell securities or other property to, the Fund, except that the Fund may in accordance with rules adopted under the 1940 Act engage in transactions with accounts that are affiliated with the Fund as a result of common officers, directors, or investment advisers or pursuant to exemptive orders granted to the Fund and/or BlackRock by the SEC. These transactions would be effected in circumstances in which BlackRock determined that it would be appropriate for the Fund to purchase and another client of BlackRock to sell, or the Fund to sell and another client of BlackRock to purchase, the same security or instrument on the same day. From time to time, the activities of the Fund may be restricted because of regulatory requirements applicable to BlackRock or its Affiliates and/or BlackRock's internal policies designed to comply with, limit the applicability of, or otherwise relate to such requirements. A client not advised by BlackRock would not be subject to some of those considerations. There may be periods when BlackRock may not initiate or recommend certain types of transactions, or may otherwise restrict or limit their advice in certain securities or instruments issued by or related to companies for which an Affiliate is performing investment banking, market making or other services or has proprietary positions. For example, when an Affiliate is engaged in an underwriting or other distribution of securities of, or advisory services for, a company, the Fund may be prohibited from or limited in purchasing or selling securities of that company. Similar situations could arise if personnel of BlackRock or its Affiliates serve as directors of companies the securities of which the Fund wishes to purchase or sell. However, if permitted by applicable law, the Fund may purchase securities or instruments that are issued by such companies or are the subject of an underwriting, distribution, or advisory assignment by an Affiliate, or in cases in which personnel of BlackRock or its Affiliates are directors or officers of the issuer.
48


Table of Contents
The investment activities of one or more Affiliates for their proprietary accounts and for client accounts may also limit the investment strategies and rights of the Fund. For example, in certain regulated industries, in certain emerging or international markets, in corporate and regulatory ownership definitions, and in certain futures and derivative transactions, there may be limits on the aggregate amount of investment by affiliated investors 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 or certain transactions undertaken, the ability of BlackRock on behalf of clients (including the Fund) to purchase or dispose of investments, or exercise rights or undertake business transactions, may be restricted by regulation or otherwise impaired. As a result, BlackRock, on behalf of clients (including the Fund), may limit purchases, sell existing investments, or otherwise restrict or limit the exercise of rights (including voting rights) 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. When ownership in certain securities nears an applicable threshold, BlackRock may limit purchases in such securities to the issuer's weighting in the applicable benchmark used by BlackRock to manage the 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.
To the extent permitted by applicable laws, BlackRock and its Affiliates may maintain securities indexes as part of their product offerings. Index based funds seek to track the performance of securities indexes and may use the name of the index in the fund name. Index providers, including BlackRock and its Affiliates may be paid licensing fees for use of their index or index name. BlackRock and its Affiliates will not be obligated to license their indexes to BlackRock, and BlackRock cannot be assured that the terms of any index licensing agreement with BlackRock and its Affiliates will be as favorable as those terms offered to other index licensees.
 
BlackRock and its Affiliates may serve as Authorized Participants in the creation and redemption of exchange-traded funds, including funds advised by Affiliates of BlackRock. As described in greater detail in the Creations and Redemptions section of the Prospectus, BlackRock and its Affiliates may therefore be deemed to be participants in a distribution of iShares funds that could render them statutory underwriters.
 
BlackRock may enter into contractual arrangements with third party service providers to the Fund (e.g., custodians, administrators) pursuant to which BlackRock receives fee discounts or concessions in recognition of BlackRock’s overall relationship with such service providers. To the extent that BlackRock is responsible for paying these service providers out of its management fee, the benefits of any such fee discounts or concessions may accrue, in whole or in part, to BlackRock. BlackRock will disclose any material benefits it receives as a result of such fee discounts or concessions to the Fund’s Board.
Present and future activities of BlackRock and its Affiliates, including BFA, in addition to those described in this section, may give rise to additional conflicts of interest.
Investment Advisory, Administrative and Distribution Services
Investment Adviser. BFA serves as investment adviser to 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,

Table of Contents
BFA, subject to the supervision of the Board and in conformity with the stated investment policies of the Fund, manages and administers the Trust and the investment of the Fund’s assets. BFA is responsible for placing purchase and sale orders and providing continuous supervision of the investment portfolio of the Fund.
Pursuant to the investment advisory agreement, BFA may, from time to time, in its sole discretion and to the extent permitted by applicable law, appoint one or more sub-advisers, including, without limitation, affiliates of BFA, to perform investment advisory or other services with respect to the Fund. In addition, BFA may delegate certain of its investment advisory functions under the investment advisory agreement to one or more of its affiliates to the extent permitted by applicable law. BFA may terminate any or all sub-advisers or such delegation arrangements in its sole discretion upon appropriate notice at any time to the extent permitted by applicable law.
BFA is responsible, under the investment advisory agreement, for substantially all expenses of the Fund, including the cost of transfer agency, custody, fund administration, legal, audit and other services. BFA is not responsible for, and the Fund will bear the cost of, interest expense, taxes, brokerage expenses and other expenses connected with the execution of portfolio securities transactions, distribution fees and extraordinary expenses.
 
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 an annual rate of 0.28%. Because the Fund has been in operation for less than one full fiscal year, this percentage reflects the rate at which BFA will be paid. BFA has contractually agreed to waive a portion of its management fees in an amount equal to the Acquired Fund Fees and Expenses attributable to the Fund's investments in other iShares funds until February 29, 2016. The contractual waiver may be terminated prior to February 29, 2016 only upon written agreement of the Trust and BFA.
 
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 February 28, 2014, 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:

Registered Investment Companies   68   $137,600,000,000
Other Pooled Investment Vehicles   16   18,500,000,000

Other Accounts   5   3,000,000,000
Accounts with Incentive-Based Fee Arrangements   1   1,000,000,000
 
Each of the portfolios or accounts for which the Portfolio Managers are primarily responsible for the day-to-day management seeks to track the rate of return, risk profile and other characteristics of independent third-party indexes by either replicating the same combination of securities that constitute those indexes or through a representative sampling of the securities that
50


Table of Contents
 
constitute those indexes based on objective criteria and data. Pursuant to BFA’s policy, investment opportunities are allocated equitably among the Fund and other portfolios and accounts. For example, under certain circumstances, an investment opportunity may be restricted due to limited supply in the market, legal constraints or other factors, in which event the investment opportunity will be allocated equitably among those portfolios and accounts, including the Fund, seeking such investment opportunity. As a consequence, from time to time the Fund may receive a smaller allocation of an investment opportunity than it would have if the Portfolio Managers and BFA and its affiliates did not manage other portfolios or accounts.
 
Like the Fund, the other portfolios or accounts for which the Portfolio Managers are primarily responsible for the day-to-day portfolio management generally pay an asset-based fee to BFA or its affiliates, as applicable, for its advisory services. One or more of those other portfolios or accounts, however, may pay BFA or its affiliates an incentive-based fee in lieu of, or in addition to, an asset-based fee for its advisory services. A portfolio or account with an incentive-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. By their nature, incentive-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 has an obligation to allocate resources and opportunities equitably among portfolios and accounts and intends 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 incentive-based fee arrangements, there is the potential for a conflict of interest that may result in the Portfolio Managers' favoring those portfolios or accounts with incentive-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 February 28, 2014:

The discussion below describes the Portfolio Managers' compensation as of March 20, 2014.
 
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.
51


Table of Contents
Discretionary Incentive Compensation. Discretionary incentive compensation is a function of several components: the performance of BlackRock, Inc., the performance of the portfolio manager's group within BlackRock, Inc. and the individual's performance and contribution to the overall performance of these portfolios and BlackRock, Inc.
Distribution of Discretionary Incentive Compensation. Discretionary incentive compensation is distributed to portfolio managers in a combination of cash and BlackRock, Inc. restricted stock units which vest ratably over a number of years. The BlackRock, Inc. restricted stock units, if properly vested, will be settled in BlackRock, Inc. common stock. Typically, the cash bonus, when combined with base salary, represents more than 60% of total compensation for the portfolio managers. Paying a portion of annual bonuses in stock puts compensation earned by a portfolio manager for a given year “at risk” based on BlackRock, Inc.'s ability to sustain and improve its performance over future periods.
Long-Term Incentive Plan Awards — From time to time, long-term incentive equity awards are granted to certain key employees to aid in retention, align their interests with long-term shareholder interests and motivate performance. Equity awards are generally granted in the form of BlackRock, Inc. restricted stock units that, once vested, settle in BlackRock, Inc. common stock.
Other Compensation Benefits. In addition to base compensation and discretionary incentive compensation, portfolio managers may be eligible to receive or participate in one or more of the following:
Incentive Savings Plans — BlackRock, Inc. has created a variety of incentive savings plans in which BlackRock, Inc. employees are eligible to participate, including a 401(k) plan, the BlackRock Retirement Savings Plan (“RSP”), and the BlackRock Employee Stock Purchase Plan (“ESPP”). The employer contribution components of the RSP include a company match equal to 50% of the first 8% of eligible pay contributed to the plan capped at $5,000 per year, and a company retirement contribution equal to 3-5% of eligible compensation up to the U.S. Internal Revenue Service (the “IRS”) limit ($255,000 for 2013). The RSP offers a range of investment options, including registered investment companies and collective investment funds managed by the firm. BlackRock, Inc. contributions follow the investment direction set by participants for their own contributions or, absent participant investment direction, are invested into an index target date fund that corresponds to, or is closest to, the year in which the participant attains age 65. The ESPP allows for investment in BlackRock, Inc. common stock at a 5% discount on the fair market value of the stock on the purchase date. Annual participation in the ESPP is limited to the purchase of 1,000 shares of common stock or a dollar value of $25,000 based on its fair market value on the Purchase Date. James Mauro and Scott Radell are each eligible to participate in these plans.
 
As of March 20, 2014, 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 of 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 200 Clarendon Street, Boston, MA 02116. 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
52


Table of Contents
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 United States. 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 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 defined 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.
Payments by BFA and its Affiliates. BFA and/or its affiliates (“BFA Entities”) 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 and other iShares funds, these payments do not increase the price paid by investors for the purchase of shares of, or the cost of owning, the Fund or other iShares funds. 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, 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 associated with the Fund or materials relating to exchange-traded products in general (“Publishing Costs”). In addition, BFA Entities make payments to Intermediaries that make shares of the Fund and certain other iShares funds available to their clients, develop new products that feature iShares or otherwise promote the Fund and other iShares funds. 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 iShares funds. 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 and other iShares funds 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.

Table of Contents
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”). Pursuant to this special, long-term and significant arrangement (the “Marketing Program”), FBS and certain affiliates (collectively “Fidelity”) have agreed, among other things, to actively promote iShares funds to customers and investment professionals 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 reduced commission rate or commission free, 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 for marketing and implementing certain brokerage and investment programs. Upon termination of the arrangement, the BFA Entities will make additional payments to FBS based upon a number of criteria, including the overall success of the Marketing Program and the level of services provided by FBS during the wind-down period.
Any additions, modifications, or deletions to Intermediaries listed above that have occurred since the date noted above 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 his or her Intermediary firm may receive. Any payments made by the BFA Entities to an Intermediary may create the incentive for an Intermediary to encourage customers to buy shares of iShares funds.
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.
