The Fund and the Underlying Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate for the Fund or the Underlying Fund may indicate higher transaction costs and may cause the Fund or the Underlying Fund to incur increased expenses. These costs, which are not reflected in the Annual Fund Operating Expenses or in the Example (except costs to the Underlying Fund included as part of Acquired Fund Fees and Expenses), affect the Fund’s performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 3% of the average value of its portfolio. To the extent the Underlying Fund incurs costs from high portfolio turnover, such costs may have a negative effect on the performance of the Fund.

The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets in U.S. dollar-denominated emerging market bonds, in one or more underlying funds that principally invest in emerging market bonds and in U.S. Treasury securities (or cash equivalents). The Fund intends to invest a substantial portion of its assets in the Underlying Fund. The Fund attempts to mitigate the interest rate risk of the underlying securities and/or the Underlying Fund (as determined by BFA) primarily through the use of positions in both U.S. Treasury futures contracts and interest rate swaps (i.e., enter into a contract or contracts in which the Fund will make fixed-rate payments while receiving floating-rate payments based on a reference rate). The bonds in which the Underlying Fund invests include both investment-grade and non-investment-grade bonds and generally have at least two years until maturity at the time of investment. The Fund may also invest in other interest rate futures contracts, including but not limited to, Eurodollar and Federal Funds futures. The Fund’s futures and interest rate swap positions are not intended to mitigate credit risk or other factors influencing the price of emerging market bonds, which may have a greater impact than interest rates.

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

The Fund may also invest in other ETFs (including other iShares funds), U.S. government securities, options and swap contracts, short-term paper, cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may have a higher degree of portfolio turnover than funds that seek to replicate the performance of an index.

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

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. The Fund is subject to certain risks, including the principal risks noted below (either directly or through its investments in the Underlying Fund), any of which may adversely affect the Fund's net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective. Unlike many ETFs, the Fund is not an index-based ETF. The order of the below risk factors does not indicate the significance of any particular risk factor.

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

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

Authorized Participant Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units (as defined in the Purchase and Sale of Fund Shares section of the Prospectus), Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes.

Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund or the Underlying Fund may “call” or repay the security before its stated maturity, and the Fund or the Underlying Fund may have to reinvest the proceeds in securities with lower yields, which would result in a decline in the Fund's or Underlying Fund's income, or in securities with greater risks or with other less favorable features.

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

Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund's or the Underlying Fund's investments are concentrated in the securities and/or other assets of 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 be unable or unwilling to make timely interest and/or principal payments when due or otherwise honor their obligations. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also adversely affect the value of the Fund’s or Underlying Fund's investment in that issuer. The degree of credit risk depends on an issuer's or counterparty's financial condition and on the terms of an obligation.

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

Cybersecurity Risk. Failures or breaches of the electronic systems of the Fund or the Underlying Fund, the Fund's or the Underlying Fund's adviser, distributor, or other service providers (including the benchmark provider), market makers, Authorized Participants, hedging counterparties to the Fund or the issuers of securities in which the Fund or the Underlying Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s service providers, market makers, Authorized Participants, hedging counterparties to the Fund or issuers of securities in which the Fund or the Underlying Fund invests.

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

Geographic Risk. A natural disaster could occur in a geographic region in which the Fund or the 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 or the Underlying Fund's investments in, or which are exposed to, the affected region.

Hedging Risk. The Fund seeks to mitigate the potential impact of interest rates on the performance of emerging market bonds by entering into positions in U.S. Treasury and other futures and interest rate swaps. The Fund’s Treasury and other futures positions are not intended to mitigate credit risk or other factors influencing the price of emerging market bonds, which may have a greater impact than interest rates. There is no guarantee that the Fund’s Treasury and other futures and interest rate swap positions will completely eliminate the interest rate risk of the long positions in emerging market bonds. In addition, when interest rates fall, long–only emerging market bond investments will perform better than the Fund’s investments. In certain falling interest rate environments, the Fund’s hedging strategy could result in disproportionately larger losses in the Treasury and other futures and interest rate swap positions as compared to gains in the long emerging market bond positions attributable to interest rate changes. There is no guarantee the Fund will have positive returns, even in environments of sharply rising interest rates in which the Fund’s Treasury and other futures and interest rate swap positions might be expected to mitigate the effects of such rises. The Fund will incur expenses when entering into Treasury and other futures and interest rate swap positions.

High Yield Securities Risk. Securities that are rated below investment-grade (commonly referred to as “junk bonds,” which may include those bonds rated below “BBB-” by S&P Global Ratings and Fitch Ratings, Inc. (“Fitch”) or “Baa3” by Moody's Investors Service, Inc. (“Moody's”)), or are unrated, may be deemed speculative, may involve greater levels of risk than higher-rated securities of similar maturity and may be more likely to default.

Illiquid Investments Risk. The Fund may invest up to an aggregate amount of 15% of its net assets in illiquid investments. An illiquid investment is any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without significantly changing the market value of the investment. To the extent the Fund holds illiquid investments, the illiquid investments may reduce the returns of the Fund because the Fund may be unable to transact at advantageous times or prices. During periods of market volatility, liquidity in the market for the Fund’s shares may be impacted by the liquidity in the market for the underlying securities or instruments held by the Fund, which could lead to the Fund’s shares trading at a premium or discount to the Fund’s NAV.

Income Risk. The Fund's income may decline when yields fall. This decline can occur because the Fund or the Underlying Fund may subsequently invest in lower-yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Underlying Fund's index are substituted, or the Fund or the Underlying Fund otherwise needs to purchase additional bonds.

Interest Rate Risk. An increase in interest rates may cause the value of securities held by the Fund or the Underlying Fund to decline, may lead to heightened volatility in the fixed-income markets and may adversely affect the liquidity of certain fixed-income investments. The historically low interest rate environment, together with recent modest rate increases, heightens the risks associated with rising interest rates. The Fund will take positions in Treasury and other futures and interest rate swaps. As a result, when interest rates decline, the Fund will underperform funds with long-only investments in the same emerging market bonds as the Fund. There is no guarantee that the Fund or Underlying Fund will have positive performance even in environments of sharply rising interest rates. There is no guarantee that the Fund or Underlying Fund will be able to successfully mitigate interest rate risk.

Interest Rate Swap Risk. Interest rate swaps are subject to risks applicable to swaps generally, including the risk that a counterparty fails to meet its obligations and the risk that the Fund is not able to liquidate such swap in a timely manner or at all, which could result in losses to the Fund. Because the Fund will invest in swaps that are subject to central clearing, these swaps are subject to the risk that a central clearinghouse will go into bankruptcy or become non-operational, and sometimes involve increased transaction costs. Counterparties to OTC swaps are not subject to these risks. An interest rate swap may fail to perform as intended and may not offset adverse changes in interest rates fully or at all. An interest rate swap may also reduce the Fund’s gains due to favorable changes in interest rates and result in losses to the Fund. Counterparties to interest rate swaps are subject to manipulation in the marketplace of the reference benchmark rate, which may affect the utility of the swap as a hedge.

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

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

Through its investment in the Underlying Fund, the Fund is exposed to Management Risk, Market Risk, and Market Trading Risk, among other risks.

Issuer Risk. The performance of the Fund depends on the performance of individual instruments to which the Fund or the Underlying Fund has exposure.The Fund may be adversely affected if an issuer of underlying securities held by the Fund or the Underlying Fund is unable or unwilling to repay principal or interest when due. Changes in the financial condition or credit rating of an issuer of those securities or counterparty on other instruments may cause the value of the securities or instruments to decline.

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

Market Risk. The Fund and the Underlying Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issue, recessions, or other events could have a significant impact on the Fund and its investments.

Market Trading Risk. The Fund and the Underlying Fund face numerous market trading risks, including the potential lack of an active market for their shares, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. Unlike some ETFs that track specific indexes, the Fund does not seek to replicate the performance of a specified index. Index-based ETFs have generally traded at prices that closely correspond to NAV. However, ETFs that do not seek to replicate the performance of a specified index have a limited trading history and, therefore, there can be no assurance as to whether, and/or the extent to which, the Fund's or Underlying Fund's shares will trade at premiums or discounts to NAV. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND'S AND THE UNDERLYING FUND'S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Non-U.S. Agency Debt Risk. The Fund invests in uncollateralized bonds issued by agencies, subdivisions or instrumentalities of foreign governments. Bonds issued by foreign government agencies, subdivisions or instrumentalities are generally backed only by the general creditworthiness and reputation of the entity issuing the bonds and may not be backed by the full faith and credit of the foreign government. Moreover, a foreign government that explicitly provides its full faith and credit to a particular entity may be, due to changed circumstances, unable or unwilling to provide that support. A non-U.S. agency’s operations and financial condition are influenced by the foreign government’s economic and other policies.

Non-U.S. Issuers Risk. Securities issued by non-U.S. issuers carry 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, regulatory and economic differences, and potential restrictions on the flow of international capital. The Fund is specifically exposed to Asian Economic Risk, Central and South American Economic Risk and Middle Eastern Economic Risk.

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

Prepayment Risk. During periods of falling interest rates, issuers of certain debt obligations may repay principal prior to the security’s maturity, which may cause the Fund or the Underlying Fund to have to reinvest in securities with lower yields or higher risk of default, resulting in a decline in the Fund’s income or return potential.

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

Reliance on Trading Partners Risk. The Fund or the Underlying Fund invests in countries or regions whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund's investments. Through its holdings of securities of certain issuers, the Fund is specifically exposed to Asian Economic Risk, Central and South American Economic Risk, European Economic Risk and U.S. Economic Risk.

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

Risk of Investing in Russia. Investing in Russian securities involves significant risks, including legal, regulatory and economic risks that are specific to Russia. In addition, investing in Russian securities involves risks associated with the settlement of portfolio transactions and loss of the Fund’s ownership rights in its portfolio securities as a result of the system of share registration and custody in Russia. A number of jurisdictions, including the U.S., Canada and the European Union (the “EU”), have imposed economic sanctions on certain Russian individuals and Russian corporate entities. Additionally, Russia is alleged to have participated in state-sponsored cyberattacks against foreign companies and foreign governments. Actual and threatened responses to such activity, including purchasing restrictions, sanctions, tariffs or cyberattacks on the Russian government or Russian companies, may impact Russia’s economy and Russian issuers of securities in which the Fund invests.

Risk of Swap Agreements. A swap is a two-party contract that generally obligates each counterparty to exchange periodic payments based on a pre-determined underlying investment or notional amount and to exchange collateral to secure the obligations of each counterparty. Swaps may be leveraged and are subject to counterparty risk, credit risk and pricing risk. Swaps may be subject to illiquidity risk, and it may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

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

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

Small Fund Risk. When the Fund’s size is small, the Fund may experience low trading volume and wide bid/ask spreads. In addition, the Fund may face the risk of being delisted if the Fund does not meet certain conditions of the listing exchange. Any resulting liquidation of the Fund could cause the Fund to incur elevated transaction costs for the Fund and negative tax consequences for its shareholders.

Sovereign and Quasi-Sovereign Obligations Risk. The Fund or the Underlying Fund may invest in securities issued by or guaranteed by sovereign governments and by entities affiliated with or backed 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.

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

Tax Risk. Because the Fund invests in the Underlying Fund, the Fund’s realized losses on sales of shares of the Underlying Fund may be indefinitely or permanently deferred as “wash sales.” Distributions of short-term capital gains by the Underlying Fund will be recognized as ordinary income by the Fund and would not be offset by the Fund’s capital loss carryforwards, if any. Capital loss carryforwards of the Underlying Fund, if any, would not offset net capital gains of the Fund. Each of these effects is caused by the Fund's investment in the Underlying Fund and may result in distributions to Fund shareholders being of higher magnitude and less likely to qualify for lower capital gain tax rates than if the Fund were to invest directly in the securities and other instruments comprising its portfolio.

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

The bar chart and table that follow show how the Fund has performed on a calendar year basis and provide an indication of the risks of investing in the Fund. Both assume that all dividends and distributions have been reinvested in the Fund. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Supplemental information about the Fund’s performance is shown under the heading Total Return Information in the Supplemental Information section of the Prospectus. If BFA had not waived certain Fund fees during certain periods, the Fund's returns would have been lower.
