The U.S. bond market posted positive returns for the 12-month period ended October 31, 2016 (the “reporting period”). The Bloomberg Barclays U.S. Aggregate Bond Index, a broad measure of U.S. bond performance, returned 4.37% for the reporting period.

The bond market’s advance reflected continued uncertainty regarding the economic environment. Overall, the U.S. economy grew by 1.5% for the 12 months ended September 30, 2016 (the most recent data available), decelerating from 2.2% for the 12 months ended September 30, 2015. Although employment growth remained robust, other segments of the economy struggled. For example, industrial production contracted during the reporting period, while consumer spending increased by just 2.2%. As a result, the economy generated three consecutive quarters of anemic growth before rebounding in the final quarter of the reporting period.

Inflation generally remained muted as the consumer price index (“CPI”) rose by 1.6% for the reporting period. Although low by historical standards, the increase in the CPI was notably higher than the 0.2% increase for the 12 months ended October 31, 2015, reflecting a recovery in energy prices after they bottomed in February 2016.

In this environment, the U.S. Federal Reserve Bank (the “Fed”) ended a seven-year period of near-zero interest rates by raising its short-term interest rate target in December 2015. The Fed’s first interest rate hike since June 2006 increased the federal funds target rate from a range of 0%-0.25% to a range of 0.25%-0.50%. Despite expectations of more Fed rate increases in 2016, the slowing economic environment and lack of inflationary pressure led the Fed to hold rates steady for the remainder of the reporting period.

The combination of decelerating economic growth and low inflation pushed most U.S. bond yields lower and bond prices higher for the reporting period. Longer-term bonds fared best as long-term yields declined the most, while short-term bond yields rose slightly, reflecting the Fed rate hike in late 2015.

Sector performance was driven by strong investor demand for yield in a low interest rate environment. Consequently, corporate bonds — which offer the highest yields in the U.S. bond market — delivered the best returns for the reporting period. Lower-quality corporate bonds outperformed as the search for yield led investors to seek out riskier segments of the corporate bond market. In particular, high-yield corporate bonds (those with credit ratings below investment grade) returned more than 10% for the reporting period. Within the corporate sector, bonds issued by utility companies produced the highest returns. Industrial bonds also fared well, led by the strong performance of energy and commodity-related securities, while financial bonds lagged.

U.S. Treasury inflation-protected securities (“TIPS”) were also among the leading performers for the reporting period. The rebound in energy prices led to increased investor demand for inflation protection, which aided performance in the TIPS market.

Mortgage-backed securities posted positive returns for the reporting period but trailed the performance of the overall U.S. bond market. Mortgage-backed securities were held in check by prepayment fears as declining interest rates led to concerns about a renewed wave of mortgage refinancing.

U.S. Treasury and government agency bonds posted the lowest returns among U.S. bonds for the reporting period. Limited demand for the relatively low yields of Treasury and agency bonds weighed on their performance, as did the general underperformance of higher-quality securities.

The inception date of the Fund was 9/25/13. The first day of secondary market trading was 9/26/13.

The Bloomberg Barclays Short-Term Government/Corporate Index (formerly the Barclays Short-Term Government/Corporate Index) is an unmanaged index that measures the performance of government and corporate securities with less than 1 year remaining to maturity.

Past performance is no guarantee of future results. Performance results do not reflect the deduction of taxes that a shareholder would pay on fund distributions or on the redemption or sale of fund shares. See “About Fund Performance” on page 12 for more information.

The iShares Short Maturity Bond ETF (the “Fund”) seeks to maximize current income by investing, under normal circumstances, at least 80% of its net assets in a portfolio of U.S. dollar-denominated investment-grade fixed income securities and maintain a weighted average maturity that is less than three years. The Fund is an actively managed exchange-traded fund that does not seek to replicate the performance of a specified index. For the 12-month reporting period ended October 31, 2016, the total return for the Fund was 1.28%, net of fees.

Short-term investment-grade bonds produced modestly positive returns for the reporting period. Short-term bond yields faced conflicting influences during the reporting period that contributed some volatility. The Fed’s decision to raise short-term interest rates in December 2015, for the first time in almost seven years, and investor expectations for more rate hikes in 2016 led to higher short-term bond yields early in the reporting period. However, growing demand for short-term bonds from investors seeking stability, particularly in response to the surprise vote by the United Kingdom to exit the European Union, pushed short-term yields lower. Near the end of the reporting period, yields on short-term bonds rose ahead of regulatory changes relating to money market funds.

In that environment, the Fund performed well on both an absolute basis and relative to the Bloomberg Barclays Short-Term Government/Corporate Index during the reporting period. The decision to underweight U.S. Treasury securities in favor of higher-yielding, non-Treasury sectors was a key contributor to relative performance. For example, the Fund’s stake in securitized bonds contributed meaningfully to performance, led by asset-backed securities (“ABS”) and commercial mortgage-backed securities (“CMBS”). ABS and CMBS were in demand for their combination of comparatively attractive yields and high credit quality. Short-term corporate securities were also a source of strength.

The Fund reduced exposure to European banks and sovereign debt ahead of the Brexit vote in June, shifting those assets into ABS. The Fund also took advantage of short-term imbalances in the market to increase its allocation to cash-equivalent securities — such as certificates of deposit, commercial paper, and repurchase agreements — while maintaining a sizable position in short-term floating-rate bonds.

The Fund’s shorter overall duration (price sensitivity to interest rate changes) and yield curve positioning reduced return contributed by falling interest rates, while also reducing volatility for the reporting period.

The Bloomberg Barclays Municipal Bond: 1 Year (1-2) Index (formerly the Barclays Municipal Bond: 1 Year (1-2) Index) is an unmanaged index comprised of national municipal bond issues having a maturity of at least one year and less than two years.

The iShares Short Maturity Municipal Bond ETF (the “Fund”) seeks to maximize tax-free current income by investing, under normal circumstances, at least 80% of its net assets in municipal securities such that the interest on each bond is exempt from U.S. federal income taxes and the federal alternative minimum tax. The Fund will also seek to maintain a weighted average maturity that is less than three years. The Fund is an actively managed exchange-traded fund that does not seek to replicate the performance of a specified index. For the 12-month reporting period ended October 31, 2016, the total return for the Fund was 0.69%, net of fees.

Short-term municipal bonds produced modestly positive returns for the reporting period. Looking at the broader U.S. bond market, longer-term bond yields fell to record lows amid modest economic growth, low inflation, and demand from investors seeking stability and yield in the wake of the surprise vote by the United Kingdom to exit the European Union. Nevertheless, yields on the shortest-term bills and notes rose following the Fed’s decision to raise interest rates in December 2015 for the first time in almost seven years.

It was a similar story in the municipal bond market, where demand for municipal bonds reached a record high at a time when supply was down year over year through June 2016. As a result, the yield on the broad-based Bloomberg Barclays Municipal Bond Index reached a record low in May 2016. However, municipal bond yields rose over the remainder of the reporting period as municipalities moved aggressively to lock in low borrowing costs. Short-term municipal bond yields rose further ahead of regulatory changes relating to money market funds.

The Fund performed well during the reporting period on both an absolute basis and relative to the Bloomberg Barclays Municipal Bond: 1 Year (1-2) Index. Outperformance was derived mainly from sector allocation decisions among health care, education, and tax-backed local and state general obligation bonds. The Fund increased its exposure to bonds maturing in two to three years, which carried attractive valuations as a result of forthcoming money market reforms.

The Bank of America Merrill Lynch 6-Month US Treasury Bill Index is an unmanaged index that measures the performance of government securities with less than 6 months remaining to maturity.

The iShares Ultra Short-Term Bond ETF (the “Fund”) seeks to provide current income consistent with preservation of capital by investing, under normal circumstances, at least 80% of its net assets in a portfolio of U.S. dollar-denominated investment-grade fixed- and floating-rate debt securities and maintain a dollar-weighted average maturity that is less than 180 days. The Fund is an actively managed exchange-traded fund that does not seek to replicate the performance of a specified index. For the 12-month reporting period ended October 31, 2016, the total return for the Fund was 0.90%, net of fees.

Short-term investment-grade bonds produced modestly positive returns for the reporting period. Short-term bond yields faced conflicting influences during the reporting period that contributed to a measure of volatility. The Fed’s decision to raise short-term interest rates in December 2015, for the first time in almost seven years, and investor expectations for more rate hikes in 2016 led to higher short-term bond yields early in the reporting period. However, growing demand for short-term bonds from investors seeking stability, particularly in response to the surprise vote by the United Kingdom to exit the European Union, pushed short-term yields lower.

The decision to underweight U.S. Treasury securities in favor of higher-yielding, non-Treasury sectors was a key contributor to relative performance. For example, corporate securities generally benefited performance as a result of investor demand for their attractive yields. In particular, the Fund’s high-quality corporate securities, which accounted for nearly 60% of the Fund’s assets on average during the reporting period, were leading sources of strength. The Fund also took advantage of the volatility and short-term imbalances in the market to increase exposure to attractively valued, high-quality securities across multiple sectors.

Past performance is no guarantee of future results. Current performance may be lower or higher than the performance data quoted. Performance data current to the most recent month-end is available at www.ishares.com. Performance results assume reinvestment of all dividends and capital gain distributions and do not reflect the deduction of taxes that a shareholder would pay on fund distributions or on the redemption or sale of fund shares. The investment return and principal value of shares will vary with changes in market conditions. Shares may be worth more or less than their original cost when they are redeemed or sold in the market. Performance for certain funds may reflect a waiver of a portion of investment advisory fees. Without such a waiver, performance would have been lower.

Net asset value or “NAV” is the value of one share of a fund as calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market return (“Market Price”) is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of a fund are listed for trading, as of the time that such fund’s NAV is calculated. Certain funds may have a NAV which is determined prior to the opening of regular trading on its listed exchange and their market returns are calculated using the midpoint of the bid/ask spread as of the opening of regular trading on the exchange. Market and NAV returns assume that dividends and capital gain distributions have been reinvested at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike a fund, an index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by a fund. These expenses negatively impact fund performance. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower.

As a shareholder of a Fund, you incur two types of costs: (1) transaction costs, including brokerage commissions on purchases and sales of fund shares and (2) ongoing costs, including management fees and other fund expenses. The expense example, which is based on an investment of $1,000 invested on May 1, 2016 and held through October 31, 2016, is intended to help you understand your ongoing costs (in dollars and cents) of investing in a Fund and to compare these costs with the ongoing costs of investing in other funds.

Actual Expenses — The table provides information about actual account values and actual expenses. Annualized expense ratios reflect contractual and voluntary fee waivers, if any. To estimate the expenses that you paid on your account over the period, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number corresponding to your Fund under the heading entitled “Expenses Paid During Period.”

Hypothetical Example for Comparison Purposes — The table also provides information about hypothetical account values and hypothetical expenses based on each Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses. You may use this information to compare the ongoing costs of investing in your Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as brokerage commissions paid on purchases and sales of fund shares. Therefore, the hypothetical examples are useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

The following table includes a rollforward for the year ended October 31, 2016 of investments whose values are classified as Level 3 as of the beginning or end of the year.

iShares U.S. ETF Trust (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. The Trust was established as a Delaware statutory trust pursuant to an Agreement and Declaration of Trust dated June 21, 2011.

These financial statements relate only to the following funds (each, a “Fund,” and collectively, the “Funds”):

Pursuant to the Trust’s organizational documents, the Funds’ officers and trustees are indemnified against certain liabilities that may arise out of the performance of their duties to the Funds. Additionally, in the normal course of business, the Funds enter into contracts with service providers that contain general indemnification clauses. The Funds’ maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Funds that have not yet occurred.

The following significant accounting policies are consistently followed by each Fund in the preparation of its financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Each Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

Each Fund’s investments are valued at fair value each day that the Fund’s listing exchange is open and, for financial reporting purposes, as of the report date should the reporting period end on a day that the Fund’s listing exchange is not open. U.S. GAAP defines fair value as the price a fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) provides oversight of the valuation of investments for the Funds. The investments of each Fund are valued pursuant to policies and procedures developed by the Global Valuation Committee and approved by the Board of Trustees of the Trust (the “Board”).

In the event that application of these methods of valuation results in a price for an investment which is deemed not to be representative of the fair value of such investment or if a price is not available, the investment will be valued based upon other available factors deemed relevant by the Global Valuation Committee, in accordance with policies approved by the Board. These factors include but are not limited to (i) attributes specific to the investment; (ii) the principal market for the investment; (iii) the customary participants in the principal market for the investment; (iv) data assumptions by market participants for the investment, if reasonably available; (v) quoted prices for similar investments in active markets; and (vi) other factors, such as future cash flows, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and/or default rates. Valuations based on such factors are reported to the Board on a quarterly basis.

The Global Valuation Committee employs various methods for calibrating valuation approaches for investments where an active market does not exist, including regular due diligence of the Trust’s pricing vendors, a regular review of key inputs and assumptions, transactional back-testing or disposition analysis to compare unrealized gains and losses to realized gains and losses, reviews of missing or stale prices, reviews of large movements in market values, and reviews of market related activity.

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgement exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The fair value hierarchy for each Fund’s investments is included in its schedule of investments.

Changes in valuation techniques may result in transfers in or out of an assigned level within the fair value hierarchy. In accordance with the Trust’s policy, transfers between different levels of the fair value hierarchy are deemed to have occurred as of the beginning of the reporting period. The categorization of values determined for financial instruments are based on the pricing transparency of the financial instruments and are not necessarily an indication of the risks associated with investing in those securities.

Security transactions are accounted for on trade date. Realized gains and losses on investment transactions are determined using the specific identification method. Interest income, including amortization and accretion of premiums and discounts on debt securities, is recognized daily on the accrual basis. Dividend income and capital gain distributions, if any, are recognized on the ex-dividend date, net of any foreign taxes withheld at source.

The Funds may enter into repurchase agreements. In a repurchase agreement, a Fund purchases a security from a counterparty who agrees to repurchase the same security at a mutually agreed upon date and price. On a daily basis, the counterparty is required to maintain collateral subject to the agreement and in value no less than the agreed repurchase amount. The agreements are conditioned upon the collateral being deposited under the Federal Reserve book entry system or held in a segregated account by the Fund’s custodian or designated sub-custodians under tri-party repurchase agreements. In the event the counterparty defaults and the fair value of the collateral declines, the Fund could experience losses, delays and costs in liquidating the collateral.

Repurchase agreements are entered into by the Funds under Master Repurchase Agreements (each, an “MRA”). The MRA permits the Funds, under certain circumstances including an event of default (such as bankruptcy or insolvency), to offset payables and/or receivables with collateral held by and/or posted to the counterparty. As a result, one single net payment is created. Bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against such a right of offset in the event of the MRA counterparty’s bankruptcy or insolvency. Based on the terms of the MRA, the Fund receives securities as collateral with a market value in excess of the repurchase price at maturity. Upon a bankruptcy or insolvency of the MRA counterparty, the Fund would recognize a liability with respect to such excess collateral. The liability reflects the Fund’s obligation under bankruptcy law to return the excess to the counterparty.

The following table summarizes the Fund’s open repurchase agreements as of October 31, 2016 which are subject to offset under an MRA:

The accounting records of the Funds are maintained in U.S. dollars. Foreign currencies, as well as investment securities and other assets and liabilities denominated in foreign currencies, are translated into U.S. dollars using exchange rates deemed appropriate by the investment adviser. Purchases and sales of securities, income receipts and expense payments are translated into U.S. dollars on the respective dates of such transactions.

Each Fund does not isolate the effect of fluctuations in foreign exchange rates from the effect of fluctuations in the market prices of securities. Such fluctuations are reflected by the Funds as a component of realized and unrealized gains and losses from investments for financial reporting purposes.

The Funds may be subject to foreign taxes (a portion of which may be reclaimable) on income, stock dividends, capital gains on investments, or certain foreign currency transactions. All foreign taxes are recorded in accordance with the applicable foreign tax regulations and rates that exist in the foreign jurisdictions in which the Funds invest. These foreign taxes, if any, are paid by the Funds and are reflected in their statements of operations as follows: foreign taxes withheld at source are presented as a reduction of income, foreign taxes on securities lending income are presented as a reduction of securities lending income, foreign taxes on stock dividends are presented as “other foreign taxes”, and foreign taxes on capital gains from sales of investments and foreign taxes on foreign currency transactions are included in their respective net realized gain (loss) categories. Foreign taxes payable or deferred as of October 31, 2016, if any, are disclosed in the Funds’ statements of assets and liabilities.

Dividends and distributions paid by each Fund are recorded on the ex-dividend dates. Distributions are determined on a tax basis and may differ from net investment income and net realized capital gains for financial reporting purposes. Dividends and distributions are paid in U.S. dollars and cannot be automatically reinvested in additional shares of the Funds.

Each Fund may lend its investment securities to approved borrowers, such as brokers, dealers and other financial institutions. The borrower pledges and maintains with the Fund collateral consisting of cash, an irrevocable letter of credit issued by a bank, or securities issued or guaranteed by the U.S. government. The initial collateral received by each Fund is required to have a value of at least 102% of the current value of the loaned securities plus the interest accrued on such securities, if any, for securities traded on U.S. exchanges and a value of at least 105% for all other securities. The collateral is maintained thereafter at a value equal to at least 100% of the current value of the securities on loan plus accrued interest, if any. The market value of the loaned securities is determined at the close of each business day of the Funds. Any additional required collateral is delivered to the Funds and any excess collateral is returned by the Funds on the next business day. During the term of the loan, each Fund is entitled to all distributions made on or in respect of the loaned securities but does not receive interest income on securities received as collateral. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within the standard time period for settlement of securities transactions.

On October 11, 2016, BlackRock, Inc. (“BlackRock”) implemented changes required by amendments to Rule 2a-7 under the 1940 Act, which governs the operations of U.S. money market funds. The Funds may be exposed to additional risks when reinvesting the cash collateral in money market funds that do not seek to maintain a stable NAV per share of $1.00 and which may be subject to redemption gates or liquidity fees under certain circumstances.

Cash received as collateral for securities on loan may be reinvested in certain short-term instruments either directly on behalf of a fund or through one or more joint accounts or money market funds, including those managed by BlackRock Fund Advisors (“BFA”), the Funds’ investment adviser, or its affiliates. As of October 31, 2016, any securities on loan were collateralized by cash and/or U.S. government obligations. Cash collateral received was invested in money market funds managed by BFA and is disclosed in the schedules of investments. The securities on loan for each Fund are also disclosed in its schedule of investments. The total value of any securities on loan as of October 31, 2016 and the total value of the related cash collateral are disclosed in the statements of assets and liabilities. Income earned by the Funds from securities lending is disclosed in the statements of operations.

BlackRock. BlackRock’s indemnity allows for full replacement of securities lent. Each Fund could suffer a loss if the value of the investments purchased with cash collateral falls below the value of the cash collateral received.

Securities lending transactions are entered into by the Funds under Master Securities Lending Agreements (“MSLA”) which provide the right, in the event of default (including bankruptcy or insolvency) for the non-defaulting party to liquidate the collateral and calculate a net exposure to the defaulting party or request additional collateral. In the event that a borrower defaults, a Fund, as lender, would offset the market value of the collateral received against the market value of the securities loaned. The value of the collateral is typically greater than that of the market value of the securities loaned, leaving the lender with a net amount payable to the defaulting party. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against such a right of offset in the event of an MSLA counterparty’s bankruptcy or insolvency. Under the MSLA, the borrower can resell or re-pledge the loaned securities, and a Fund can reinvest cash collateral, or, upon an event of default, resell or re-pledge the collateral.

The following table is a summary of securities lending agreements which are subject to offset under an MSLA as of October 31, 2016:

Pursuant to an Investment Advisory Agreement with the Trust, BFA manages the investment of each Fund’s assets. BFA is a California corporation indirectly owned by BlackRock. Under the Investment Advisory Agreement, BFA is responsible for substantially all expenses of the Funds, except interest, taxes, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution fees, litigation expenses and any extraordinary expenses.

For its investment advisory services to each of the following Funds, BFA is entitled to an annual investment advisory fee based on the average daily net assets of each Fund as follows:

Effective December 16, 2016, for its investment advisory services to the iShares Ultra Short-Term Bond ETF, BFA will be entitled to an annual investment advisory fee of 0.08% based on the average daily net assets of the Fund.

For its investment advisory services to the iShares Short Maturity Municipal Bond ETF, BFA is entitled to an annual investment advisory fee of 0.25% based on the average daily net assets of the Fund. In addition, the Fund indirectly pays its pro rata share of fees and expenses attributable to its investments in other investment companies (“acquired fund fees and expenses”). BFA’s contractual agreement to waive a portion of its investment advisory fees in an amount equal to the acquired fund fees and expenses attributable to the Fund’s investments in other registered investment companies advised by BFA or its affiliates, if any, expired on February 29, 2016.

The U.S. Securities and Exchange Commission (the “SEC”) has issued an exemptive order which permits BlackRock Institutional Trust Company, N.A. (“BTC”), an affiliate of BFA, to serve as securities lending agent for the Funds, subject to applicable conditions. As securities lending agent, BTC bears all operational costs directly related to securities lending. Each Fund is responsible for fees in connection with the investment of cash collateral received for securities on loan in a money market fund managed by BFA, however, BTC has agreed to reduce the amount of securities lending income it receives in order to effectively limit the collateral investment fees each Fund bears to an annual rate of 0.04% (the “collateral investment fees”). Securities lending income is equal to the total of income earned from the reinvestment of cash collateral, net of fees and other payments to and from borrowers of securities, and less the collateral investment fees. The Funds retain a portion of securities lending income and remit the remaining portion to BTC as compensation for its services as securities lending agent.

Pursuant to a securities lending agreement, each Fund retains 80% of securities lending income and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees. In addition, commencing the business day following the date that the aggregate securities lending income plus the collateral investment fees generated across all 1940 Act iShares exchange-traded funds (the “iShares ETF Complex”) in a given calendar year exceeds the aggregate securities lending income generated across the iShares ETF Complex in the calendar year 2013, each Fund, pursuant to a securities lending agreement, will retain for the remainder of that calendar year 85% of securities lending income and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees.

For the year ended October 31, 2016, the total of securities lending agent services and collateral investment fees paid were as follows:

BlackRock Investments, LLC, an affiliate of BFA, is the distributor for each Fund. Pursuant to the distribution agreement, BFA is responsible for any fees or expenses for distribution services provided to the Funds.

Each Fund may invest its positive cash balances in certain money market funds managed by BFA or an affiliate. The income earned on these temporary cash investments is included in “Dividends – affiliated” in the statements of operations.

The PNC Financial Services Group, Inc. is the largest stockholder of BlackRock and is considered to be an affiliate of the Funds for 1940 Act purposes.

Purchases and sales of investments (excluding in-kind transactions and short-term investments) for the year ended October 31, 2016 were as follows:

There were no in-kind transactions (see Note 4) for the year ended October 31, 2016.

Capital shares are issued and redeemed by each Fund only in aggregations of a specified number of shares or multiples thereof (“Creation Units”) at NAV. Except when aggregated in Creation Units, shares of each Fund are not redeemable. Transactions in capital shares for each Fund are disclosed in detail in the statements of changes in net assets.

The consideration for the purchase of Creation Units of a fund in the Trust generally consists of the in-kind deposit of a designated portfolio of securities and a specified amount of cash. Certain funds in the Trust may be offered in Creation Units solely or partially for cash in U.S. dollars. Investors purchasing and redeeming Creation Units may pay a purchase transaction fee and a redemption transaction fee directly to State Street Bank and Trust Company, the Trust’s administrator, to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units, including Creation Units for cash. Investors transacting in Creation Units for cash may also pay an additional variable charge to compensate the relevant fund for certain transaction costs (i.e., stamp taxes, taxes on currency or other financial transactions, and brokerage costs) and market impact expenses relating to investing in portfolio securities. Such variable charges, if any, are included in “Proceeds from shares sold” in the statements of changes in net assets.

Each Fund may enter into forward currency contracts for the purpose of hedging against the effects of foreign currencies on the value of such Fund’s assets that are denominated in a non-U.S. currency. A forward currency contract is an obligation to purchase or sell a currency against another currency at a specified future date at an agreed upon price and quantity. Forward currency contracts are traded over-the-counter (“OTC”) and not on an organized exchange. The contract is marked-to-market daily and the change in market value is recorded as unrealized appreciation or depreciation. When the contract is closed, a realized gain or loss equal to the difference between the value at the time it was opened and the value at the time it was closed is recorded. Losses may arise if there are unfavorable movements in the value of a foreign currency relative to the U.S. dollar or if the counterparties do not meet the terms of the agreement. The Fund’s use of forward currency contracts also involves the risks of imperfect correlation between the value of its currency positions and its other investments or the Fund failing to close out its position due to an illiquid market.

The following table shows the value of forward currency contracts held by the iShares Short Maturity Bond ETF as of October 31, 2016 and the related locations in the statement of assets and liabilities, presented by risk exposure category:

The following table shows the realized and unrealized gains (losses) on forward currency contracts held by the iShares Short Maturity Bond ETF during the year ended October 31, 2016 and the related locations in the statement of operations, presented by risk exposure category:

For the year ended October 31, 2016, the average quarter-end amounts purchased and sold in U.S. dollars for the iShares Short Maturity Bond ETF were $113,816 and $80,483,377, respectively.

The Funds’ risk of loss from counterparty credit risk on OTC derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Funds. In order to better define their contractual rights and to secure rights that will help the Funds to mitigate their counterparty risk, the Funds may enter into an International Swaps and Derivatives Association, Inc. master agreement (“ISDA Master Agreement”) or similar agreement with their derivative contract counterparties. An ISDA Master Agreement is a bilateral agreement between the Funds and a counterparty that governs OTC derivatives and foreign exchange contracts and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default including the bankruptcy or insolvency of the counterparty. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy or insolvency.

The collateral requirements under an ISDA Master Agreement are typically calculated by netting the mark-to-market amount for each transaction under such agreement, and comparing that amount to the value of any collateral currently pledged by the parties. Forward currency contracts held by the Funds generally do not require collateral. To the extent amounts due to the Funds from the counterparty are not fully collateralized, contractually or otherwise, the Funds bear the risk of loss from counterparty non-performance. The Funds attempt to mitigate counterparty risk by only entering into agreements with counterparties that they believe have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.

For financial reporting purposes, the Funds do not offset financial assets and financial liabilities that are subject to netting arrangements in the statements of assets and liabilities.

The following table presents the exposure of the open forward currency contracts held by the iShares Short Maturity Bond ETF that are subject to potential offset in the statement of assets and liabilities as of October 31, 2016:

In the normal course of business, each Fund’s investment activities expose it to various types of risk associated with the financial instruments and markets in which it invests. The significant types of financial risks each Fund is exposed to include market risk and credit risk. Each Fund’s prospectus provides details of these and other types of risk.

Market risk arises mainly from uncertainty about future values of financial instruments influenced by price, currency and interest rate movements. It represents the potential loss a fund may suffer through holding market positions in the face of market movements. A fund is exposed to market risk by virtue of its investment in equity, fixed income and/or financial derivative instruments or indirectly by virtue of its investment in underlying funds. The fair value of securities held by a fund may decline due to general market conditions, economic trends or events that are not specifically related to the issuers of the securities including local, regional or global political, social or economic instability or to factors that affect a particular industry or group of industries. The extent of a fund’s exposure to market risk is the market value of the investments held as shown in the fund’s schedule of investments.

A diversified portfolio, where this is appropriate and consistent with a fund’s objectives, minimizes the risk that a price change of a particular investment will have a material impact on the NAV of a fund. The investment concentrations within each Fund’s portfolio are disclosed in its schedule of investments.

Changes in market interest rates or economic conditions may affect the value and/or liquidity of fixed income investments. Interest rate risk is the risk that prices of bonds and other fixed-income securities will decrease as interest rates rise and increase as interest rates fall. Mortgage-backed securities and securities with longer durations tend to be more sensitive to interest rate changes, usually making them more volatile than other types of bonds or securities with shorter durations. Given the environment of historically low interest rates, a fund may be subject to a greater risk of price losses if interest rates rise.

Credit risk is the risk that an issuer or guarantor of debt instruments or the counterparty to a financial transaction, including derivatives contracts, repurchase agreements or loans of portfolio securities, is unable or unwilling to make timely interest and/or principal payments or to otherwise honor its obligations. BFA and its affiliates manage counterparty credit risk by entering into transactions only with counterparties that they believe have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose a fund to issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of a fund’s exposure to credit and counterparty risks with respect to those financial assets is approximated by their value recorded in its statement of assets and liabilities.

High yield securities that are rated below investment-grade (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 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 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 companies or by highly leveraged (indebted) companies, which are generally less able than more financially stable companies to make scheduled payments of interest and principal.

Municipal securities are subject to the risk that litigation, legislation or other political events, local business or economic conditions, credit rating downgrades, or the bankruptcy of the issuer could have a significant effect on an issuer’s ability to make payments of principal and/or interest or otherwise affect the value of such securities. Municipal securities can be significantly affected by political changes as well as uncertainties in the municipal market related to government regulation, taxation, legislative changes or the rights of municipal security holders. Because many municipal securities are issued to finance similar projects, such as those related to education, health care, housing, transportation, utilities, and water and sewer, conditions in these sectors can affect the overall municipal market. In addition, changes in the financial condition of an individual municipal insurer can affect the overall municipal market. Municipal securities backed by current or anticipated revenues from a specific project or specific assets can be negatively affected by the discontinuance of the taxation supporting the project or assets or the inability to collect revenues for the project or from the assets.

Each Fund is treated as an entity separate from the Trust’s other funds for federal income tax purposes. It is the policy of each Fund to qualify as a regulated investment company by complying with the provisions applicable to regulated investment companies, as defined under Subchapter M of the Internal Revenue Code of 1986, as amended, and to annually distribute substantially all of its ordinary income and any net capital gains (taking into account any capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income and excise taxes. Accordingly, no provision for federal income taxes is required.

U.S. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or NAV per share. The following permanent differences as of October 31, 2016, attributable to the use of amortization methods on fixed income securities, foreign currency transactions and undistributed gains, were reclassified to the following accounts:

The tax character of distributions paid during the years ended October 31, 2016 and October 31, 2015 was as follows:

As of October 31, 2016, the tax components of accumulated net earnings (losses) were as follows:

As of October 31, 2016, the following Funds had non-expiring capital loss carryforwards available to offset future realized capital gains as follows:

Management has analyzed tax laws and regulations and their application to the Funds as of October 31, 2016, inclusive of the open tax return years, and does not believe there are any uncertain tax positions that require recognition of a tax liability in the Funds’ financial statements.

Management has evaluated the impact of all subsequent events on the Funds through the date the financial statements were available to be issued and has determined that there were no subsequent events requiring adjustment or disclosure in the financial statements.

In our opinion, the accompanying statements of assets and liabilities, including the schedules of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of iShares Short Maturity Bond ETF, iShares Short Maturity Municipal Bond ETF and iShares Ultra Short-Term Bond ETF (the “Funds”) at October 31, 2016, the results of each of their operations, the changes in each of their net assets and their financial highlights for each of the periods presented, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at October 31, 2016 by correspondence with the custodian, transfer agent and brokers, provide a reasonable basis for our opinion.

For the fiscal year ended October 31, 2016, the following Funds hereby designate the following maximum amounts allowable as interest-related dividends eligible for exemption from U.S. withholding tax for nonresident aliens and foreign corporations:

The following Funds hereby designate the following amounts of distributions from direct federal obligation interest for the fiscal year ended October 31, 2016:

The law varies in each state as to whether and what percentage of ordinary income dividends attributable to federal obligations is exempt from state income tax. Shareholders are advised to check with their tax advisers to determine if any portion of the dividends received is exempt from state income tax.

I. iShares Short Maturity Bond ETF and iShares Short Maturity Municipal Bond ETF

Under Section 15(c) of the Investment Company Act of 1940 (the “1940 Act”), the Trust’s Board of Trustees (the “Board”), including a majority of Trustees who are not “interested persons” of the Trust (as that term is defined in the 1940 Act) (the “Independent Trustees”), is required annually to consider and approve the Investment Advisory Contract between the Trust and BFA (the “Advisory Contract”) on behalf of the Funds. The Independent Trustees requested, and BFA provided, such information as the Independent Trustees, with advice from independent counsel, deemed reasonably necessary to evaluate the Advisory Contract. A committee of all of the Independent Trustees (the “15(c) Committee”), with independent counsel, met with management on April 28, 2016 and May 9, 2016. At these meetings, the 15(c) Committee reviewed and discussed information provided in response to the 15(c) Committee’s initial requests, and requested certain additional information, which management agreed to provide. At a meeting held on May 17, 2016, management presented information to the Board relating to the continuance of the Advisory Contract, including information requested by the 15(c) Committee during its meetings. The Board, including the Independent Trustees, reviewed and discussed such information at length. The Independent Trustees requested from management certain additional information, which management agreed to provide. At a meeting held on June 21-23, 2016, the Board, including the Independent Trustees, reviewed the additional information provided by management in response to these requests. After extensive discussions, the Board, including all of the Independent Trustees, approved the continuance of the Advisory Contract for the Funds, based on a review of qualitative and quantitative information provided by BFA, including the additional information management provided at the request of the Independent Trustees. The Board noted its satisfaction with the extent and quality of information provided and its frequent interactions with management, as well as the detailed responses and other information provided by BFA. The Board also noted that the Board and BFA agreed to discuss potential enhancements and adjustments to the 15(c) process for the coming year. The Independent Trustees were advised by their independent counsel throughout the process, including about the legal standards applicable to their review. In approving the Advisory Contract for the Funds, the Board, including the Independent Trustees, considered the following factors, no one of which was controlling, and reached the following conclusions:

Expenses and Performance of the Funds — The Board reviewed statistical information prepared by Broadridge Financial Solutions Inc. (“Broadridge”), an independent provider of investment company data, regarding the expense ratio components, including gross and net total expenses, waivers/reimbursements (if any), and underlying fund fees and expenses (if any) of each Fund in comparison with the same information for other exchange traded funds (including, where applicable, funds sponsored by an “at cost” service provider) and, in the limited instances where no comparable ETFs existed and the comparison group would not otherwise be reasonable in Broadridge’s judgment, pure index institutional mutual funds, objectively selected by Broadridge as comprising such Fund’s applicable peer group pursuant to Broadridge’s proprietary ETF methodology (the “Peer Group”). The Board was provided with a detailed description of Broadridge’s proprietary ETF methodology used by Broadridge to determine the applicable Peer Groups. The Board further noted that due to the limitations in providing comparable funds in the various Peer Groups, the statistical information provided in Broadridge’s report may or may not provide meaningful direct comparisons to the Funds in all instances.

The Board also noted that the investment advisory fee rates and overall expenses (net of waivers and reimbursements) for the Funds were lower than the median of the investment advisory fee rates and overall expenses (net of waivers and reimbursements) of the funds in their respective Peer Group, excluding iShares funds.

In addition, to the extent that any of the comparison funds included in the Peer Group, excluding iShares funds, track the same index as any particular Fund, Broadridge also provided, and the Board reviewed, a comparison of such Fund’s performance for the one-, three-, five-, ten-year, and since inception periods, as applicable, and for the “last quarter” period ended December 31, 2015, to that of such relevant comparison funds for the same periods.

The Board noted that each Fund is an actively managed ETF that does not seek to track the performance of a specified index and that the management team for each Fund manages the Fund’s portfolio in accordance with its investment objective. The Board further noted that during the prior year, the Board received periodic reports on each Fund’s short- and longer-term performance in comparison with its peer group and benchmark index. Such periodic comparative performance information, including additional detailed information on certain specific iShares funds requested by the Board, was also considered. The Board noted that each Fund generally performed in line with expectations relative to each Fund’s peer group and benchmark index.

Based on this review, the other factors considered at the meeting, and their general knowledge of ETF pricing, the Board concluded that the investment advisory fee rate and expense level and the historical performance of each Fund supported the Board’s approval of the continuance of the Advisory Contract for the coming year.

Nature, Extent and Quality of Services Provided by BFA — Based on management’s representations, including information about recent and proposed enhancements to the iShares business, including with respect to capital markets support and analysis, product design and other services, the Board expected that there would be no diminution in the scope of services required of or provided by BFA under the Advisory Contract for the coming year as compared to the scope of services provided by BFA during prior years. In reviewing the scope of these services, the Board considered BFA’s investment philosophy and experience, noting that BFA and its affiliates have committed significant resources over time, including during the past year, to supporting the iShares funds and their shareholders. The Board also considered BFA’s compliance program and its compliance record with respect to the Funds. In that regard, the Board noted that BFA reports to the Board about portfolio management and compliance matters on a periodic basis in connection with regularly scheduled meetings of the Board, and on other occasions as necessary and appropriate, and has provided information and made appropriate officers available as needed to provide further assistance with these matters. The Board also reviewed the background and experience of the persons responsible for the day-to-day management of the Funds, as well as the resources available to them in managing the Funds. In addition to the above considerations, the Board reviewed and considered detailed presentations regarding BFA’s investment performance, investment and risk management processes and strategies provided at the June 21-23, 2016 meeting and throughout the previous year, and matters related to BFA’s portfolio compliance policies and procedures. The Board noted that each Fund had met its investment objective consistently since its respective inception date.

Based on review of this information, and the performance information discussed above, the Board concluded that the nature, extent and quality of services provided by BFA to the Funds under the Advisory Contract supported the Board’s approval of the continuance of the Advisory Contract for the coming year.

Costs of Services Provided to the Funds and Profits Realized by BFA and its Affiliates — The Board reviewed information about the profitability to BlackRock of the Funds, on a Fund-by-Fund basis and in the aggregate, based on the fees payable to BFA and its affiliates (including fees under the Advisory Contract), and all other sources of revenue and expense to BFA and its affiliates from the Funds’ operations for the last calendar year. The Board reviewed BlackRock’s profitability methodology for the iShares funds, noting that the 15(c) Committee had focused on the methodology and profitability presentation during its meetings. The Board discussed the sources of direct and ancillary revenue with management, including the revenues to BTC from securities lending by the Funds. The Board also discussed BFA’s profit margin as reflected in the Funds’ profitability analyses and reviewed information regarding potential economies of scale (as discussed below). Based on this review, the Board concluded that the profits realized by BFA and its affiliates under the Advisory Contract and from other relationships between the Funds and BFA and/or its affiliates, if any, were within a reasonable range in light of the factors considered.

Economies of Scale — The Board reviewed information regarding potential economies of scale or other efficiencies that may result from increases in the Funds’ assets, noting that the issue of economies of scale had been focused on extensively by the 15(c) Committee during its meetings and addressed by management. The Board and the 15(c) Committee reviewed information

provided by BFA regarding scale benefits shared with the iShares funds through relatively low fee rates established at inception, breakpoints, waivers, or other fee reductions, as well as through additional investment in the iShares business and the provision of improved or additional infrastructure and services to the iShares funds and their shareholders. The Board and the 15(c) Committee received information regarding BlackRock’s historical profitability, including BFA’s and its affiliates’ costs in providing services. The cost information distinguished, among other things, between fixed and variable costs, and explained how the level of fixed and variable costs, as well as the nature of such costs, may impact the existence or size of scale benefits. The Board noted that the Advisory Contract for the Funds did not provide for any breakpoints in the Funds’ investment advisory fee rates as the assets of the Funds increase. However, the Board noted that should material economies of scale exist in the future that are not otherwise shared, a breakpoint structure for the Funds may be appropriate, and that it would continue to monitor the sharing of economies of scale to determine the appropriateness of adding breakpoints in the future.

Based on this review, as well as the other factors considered at the meeting, the Board, recognizing its responsibility to consider this issue periodically, determined to approve the continuance of the Advisory Contract for the coming year.

Fees and Services Provided for Other Comparable Funds/Accounts Managed by BFA and its Affiliates — The Board received and considered information regarding the investment advisory/management fee rates for other funds/accounts in the U.S. for which BFA (or its affiliates) provides investment advisory/management services, including open-end funds registered under the 1940 Act (including sub-advised funds), collective trust funds, and institutional separate accounts (together, the “Other Accounts”), and acknowledged BFA’s assertion that the iShares funds are fundamentally different investment vehicles from the Other Accounts. The Board noted that BFA and its affiliates do manage Other Accounts with similar investment strategies or investment mandates as the Funds. The Board further noted that BFA provided the Board with detailed information regarding how the Other Accounts (particularly institutional clients) generally differ from the Funds, including in terms of the different and generally more extensive services provided to the Funds, as well as other significant differences. In that regard, the Board considered that the pricing of services to institutional clients is typically based on a number of factors beyond the nature and extent of the specific services to be provided and often depends on the overall relationship between the client and its affiliates and the adviser and its affiliates. In addition, the Board considered the relative complexity and inherent risks and challenges of managing and providing other services to the Funds, as publicly traded exchange traded funds, as compared to the Other Accounts that are institutional clients in light of differing regulatory requirements and client-imposed mandates. The Board also considered the “all-inclusive” nature of the Funds’ advisory fee structure, and the Fund expenses borne by BFA under this arrangement. The Board noted that the investment advisory fee rates under the Advisory Contract for the Funds were generally higher than the investment advisory/management fee rates for certain of the Other Accounts (particularly institutional clients) and concluded that the differences appeared to be consistent with the factors discussed.

Other Benefits to BFA and/or its Affiliates — The Board reviewed the “fallout” benefits or ancillary revenue received by BFA and/or its affiliates in connection with the services provided to the Funds by BFA, such as payment of revenue to BTC, the Funds’ securities lending agent, for loaning portfolio securities (which was included in the profit margins reviewed by the Board pursuant to BFA’s profitability methodology), and payment of advisory fees and/or administration fees to BFA and BTC (or their affiliates) in connection with any investments by the Funds in other funds for which BFA (or its affiliates) provides investment advisory services and/or administration services. The Board noted that BFA generally does not use soft dollars or consider the value of research or other services that may be provided to BFA (including its affiliates) in selecting brokers for portfolio transactions for the Funds. The Board further noted that any portfolio transactions on behalf of the Funds placed through a BFA affiliate or purchased from an underwriting syndicate in which a BFA affiliate participates, are reported to the Board pursuant to Rule 17e-1 or Rule 10f-3, as applicable, under the 1940 Act. The Board concluded that any such ancillary benefits would not be disadvantageous to the Funds’ shareholders and thus would not alter the Board’s conclusion with respect to the appropriateness of approving the continuance of the Advisory Contract for the coming year.

Based on the considerations described above, the Board determined that each Fund’s investment advisory fee rate under the Advisory Contract does not constitute a fee that is so disproportionately large as to bear no reasonable relationship to the services rendered and that could not have been the product of arm’s-length bargaining, and concluded that it is in the best interest of each Fund and its shareholders to approve the continuance of the Advisory Contract for the coming year.

Under Section 15(c) of the Investment Company Act of 1940 (the “1940 Act”), the Trust’s Board of Trustees (the “Board”), including a majority of Trustees who are not “interested persons” of the Trust (as that term is defined in the 1940 Act) (the “Independent Trustees”), is required annually to consider and approve the Investment Advisory Contract between the Trust and BFA (the “Advisory Contract”) on behalf of the Fund. The Independent Trustees requested, and BFA provided, such information as the Independent Trustees, with advice from independent counsel, deemed reasonably necessary to evaluate the Advisory Contract. A committee of all of the Independent Trustees (the “15(c) Committee”), with independent counsel, met with management on April 28, 2016 and May 9, 2016. At these meetings, the 15(c) Committee reviewed and discussed information provided in response to the 15(c) Committee’s initial requests, and requested certain additional information, which management agreed to provide. At a meeting held on May 17, 2016, management presented information to the Board relating to the continuance of the Advisory Contract, including information requested by the 15(c) Committee during its meetings. The Board, including the Independent Trustees, reviewed and discussed such information at length. The Independent Trustees requested from management certain additional information, which management agreed to provide. At a meeting held on June 21-23, 2016, the Board, including the Independent Trustees, reviewed the additional information provided by management in response to these requests. After extensive discussions, the Board, including all of the Independent Trustees, approved the continuance of the Advisory Contract for the Fund, based on a review of qualitative and quantitative information provided by BFA, including the additional information management provided at the request of the Independent Trustees. The Board noted its satisfaction with the extent and quality of information provided and its frequent interactions with management, as well as the detailed responses and other information provided by BFA. The Board also noted that the Board and BFA agreed to discuss potential enhancements and adjustments to the 15(c) process for the coming year. The Independent Trustees were advised by their independent counsel throughout the process, including about the legal standards applicable to their review. In approving the Advisory Contract for the Fund, the Board, including the Independent Trustees, considered the following factors, no one of which was controlling, and reached the following conclusions:

Expenses and Performance of the Fund — The Board reviewed statistical information prepared by Broadridge Financial Solutions Inc. (“Broadridge”), an independent provider of investment company data, regarding the expense ratio components, including gross and net total expenses, waivers/reimbursements (if any), and underlying fund fees and expenses (if any) of the Fund in comparison with the same information for other exchange traded funds (including, where applicable, funds sponsored by an “at cost” service provider) and, in the limited instances where no comparable ETFs existed and the comparison group would not otherwise be reasonable in Broadridge’s judgment, pure index institutional mutual funds, objectively selected by Broadridge as comprising the Fund’s applicable peer group pursuant to Broadridge’s proprietary ETF methodology (the “Peer Group”). The Board was provided with a detailed description of Broadridge’s proprietary ETF methodology used by Broadridge to determine the Fund’s Peer Group. The Board further noted that due to the limitations in providing comparable funds in the Peer Group, the statistical information provided in Broadridge’s report may or may not provide meaningful direct comparisons to the Fund in all instances.

In addition, to the extent that any of the comparison funds included in the Peer Group, excluding iShares funds, track the same index as the Fund, Broadridge also provided, and the Board reviewed, a comparison of the Fund’s performance for the one-, three-, five-, ten-year, and since inception periods, as applicable, and for the “last quarter” period ended December 31, 2015, to that of such relevant comparison funds for the same periods.

The Board noted that the Fund is an actively managed ETF that does not seek to track the performance of a specified index and that the management team for the Fund manages the Fund’s portfolio in accordance with its investment objective. The Board further noted that during the prior year, the Board received periodic reports on the Fund’s short- and longer-term performance in comparison with its peer group and benchmark index. Such periodic comparative performance information, including additional detailed information on certain specific iShares funds requested by the Board, was also considered. The Board noted that the Fund generally performed in line with expectations relative to the Fund’s peer group and benchmark index over the relevant periods over the relevant periods.

Based on this review, the other factors considered at the meeting, and their general knowledge of ETF pricing, the Board concluded that the investment advisory fee rate and expense level and the historical performance of the Fund supported the Board’s approval of the continuance of the Advisory Contract for the coming year.

Nature, Extent and Quality of Services Provided by BFA — Based on management’s representations, including information about recent and proposed enhancements to the iShares business, including with respect to capital markets support and analysis, product design and other services, the Board expected that there would be no diminution in the scope of services required of or provided by BFA under the Advisory Contract for the coming year as compared to the scope of services provided by BFA during prior years. In reviewing the scope of these services, the Board considered BFA’s investment philosophy and experience, noting that BFA and its affiliates have committed significant resources over time, including during the past year, to supporting the iShares funds and their shareholders. The Board also considered BFA’s compliance program and its compliance record with respect to the Fund. In that regard, the Board noted that BFA reports to the Board about portfolio management and compliance matters on a periodic basis in connection with regularly scheduled meetings of the Board, and on other occasions as necessary and appropriate, and has provided information and made appropriate officers available as needed to provide further assistance with these matters. The Board also reviewed the background and experience of the persons responsible for the day-to-day management of the Fund, as well as the resources available to them in managing the Fund. In addition to the above considerations, the Board reviewed and considered detailed presentations regarding BFA’s investment performance, investment and risk management processes and strategies provided at the June 21-23, 2016 meeting and throughout the previous year, and matters related to BFA’s portfolio compliance policies and procedures. The Board noted that the Fund had met its investment objective consistently since its inception date.

Based on review of this information, and the performance information discussed above, the Board concluded that the nature, extent and quality of services provided by BFA to the Fund under the Advisory Contract supported the Board’s approval of the continuance of the Advisory Contract for the coming year.

Costs of Services Provided to the Fund and Profits Realized by BFA and its Affiliates — The Board reviewed information about the profitability to BlackRock of the Fund, based on the fees payable to BFA and its affiliates (including fees under the Advisory Contract), and all other sources of revenue and expense to BFA and its affiliates from the Funds’ operations for the last calendar year. The Board reviewed BlackRock’s profitability methodology for the iShares funds, noting that the 15(c) Committee had focused on the methodology and profitability presentation during its meetings. The Board discussed the sources of direct and ancillary revenue with management, including the revenues to BTC from securities lending by the Fund. The Board also discussed BFA’s profit margin as reflected in the Fund’s profitability analysis and reviewed information regarding potential economies of scale (as discussed below). Based on this review, the Board concluded that the profits realized by BFA and its

affiliates under the Advisory Contract and from other relationships between the Fund and BFA and/or its affiliates, if any, were within a reasonable range in light of the factors considered.

Economies of Scale — The Board reviewed information regarding potential economies of scale or other efficiencies that may result from increases in the Fund’s assets, noting that the issue of economies of scale had been focused on extensively by the 15(c) Committee during its meetings and addressed by management. The Board and the 15(c) Committee reviewed information provided by BFA regarding scale benefits shared with the iShares funds through relatively low fee rates established at inception, breakpoints, waivers, or other fee reductions, as well as through additional investment in the iShares business and the provision of improved or additional infrastructure and services to the iShares funds and their shareholders. The Board and the 15(c) Committee received information regarding BlackRock’s historical profitability, including BFA’s and its affiliates’ costs in providing services. The cost information distinguished, among other things, between fixed and variable costs, and explained how the level of fixed and variable costs, as well as the nature of such costs, may impact the existence or size of scale benefits. The Board noted that the Advisory Contract for the Fund did not provide for any breakpoints in the Fund’s investment advisory fee rate as the assets of the Fund increase. However, the Board noted that should material economies of scale exist in the future that are not otherwise shared, a breakpoint structure for the Fund may be appropriate, and that it would continue to monitor the sharing of economies of scale to determine the appropriateness of adding breakpoints in the future.

Fees and Services Provided for Other Comparable Funds/Accounts Managed by BFA and its Affiliates — The Board received and considered information regarding the investment advisory/management fee rates for other funds/accounts in the U.S. for which BFA (or its affiliates) provides investment advisory/management services, including open-end funds registered under the 1940 Act (including sub-advised funds), collective trust funds, and institutional separate accounts (together, the “Other Accounts”), and acknowledged BFA’s assertion that the iShares funds are fundamentally different investment vehicles from the Other Accounts. The Board noted that BFA and its affiliates do manage Other Accounts with a similar investment strategy or investment mandate as the Fund. The Board further noted that BFA provided the Board with detailed information regarding how the Other Accounts (particularly institutional clients) generally differ from the Fund, including in terms of the different and generally more extensive services provided to the Fund, as well as other significant differences. In that regard, the Board considered that the pricing of services to institutional clients is typically based on a number of factors beyond the nature and extent of the specific services to be provided and often depends on the overall relationship between the client and its affiliates and the adviser and its affiliates. In addition, the Board considered the relative complexity and inherent risks and challenges of managing and providing other services to the Fund, as a publicly traded exchange traded fund, as compared to the Other Accounts that are institutional clients in light of differing regulatory requirements and client-imposed mandates. Further, with respect to comparisons with one or more open-end index mutual funds registered under the 1940 Act managed by BFA (or an affiliate) that track the same index as the Fund and have investment advisory fee rates and overall expenses (net of waivers and reimbursements) that are lower than the investment advisory fee rate and overall expenses (net of waivers and reimbursements) of the Fund, the Board gave weight to management’s explanations of the relevant circumstances applicable to such mutual funds. The Board also considered the “all-inclusive” nature of the Fund’s advisory fee structure, and the Fund expenses borne by BFA under this arrangement. The Board noted that the investment advisory fee rate under the Advisory Contract for the Fund was generally higher than the investment advisory/management fee rates for certain of the Other Accounts (particularly institutional clients) and concluded that the differences appeared to be consistent with the factors discussed.

The Board noted that BFA generally does not use soft dollars or consider the value of research or other services that may be provided to BFA (including its affiliates) in selecting brokers for portfolio transactions for the Fund. The Board further noted that any portfolio transactions on behalf of the Fund placed through a BFA affiliate or purchased from an underwriting syndicate in which a BFA affiliate participates, are reported to the Board pursuant to Rule 17e-1 or Rule 10f-3, as applicable, under the 1940 Act.

The amounts and sources of distributions reported are estimates and are provided pursuant to regulatory requirements and are not being provided for tax reporting purposes. The actual amounts and sources for tax reporting purposes will depend upon each Fund’s investment experience during the year and may be subject to changes based on the tax regulations. Shareholders will receive a Form 1099-DIV each calendar year that will inform them how to report these distributions for federal income tax purposes.

The Premium/Discount Information section is intended to present information about the differences between the daily market price on secondary markets for shares of a fund and that fund’s NAV. NAV is the price at which a fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The “Market Price” of a fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which the shares of such fund are listed for trading, as of the time that the fund’s NAV is calculated. A fund’s Market Price may be at, above or below its NAV. The NAV of a fund will fluctuate with changes in the fair value of its portfolio holdings. The Market Price of a fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

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

The following information shows the frequency of distributions of premiums and discounts for each of the Funds. The information shown for each Fund is for five calendar years (or from the inception date of such Fund if less than five years) through the date of the most recent calendar quarter-end. The specific periods covered for each Fund are disclosed in the table for such Fund.

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

The Board of Trustees has responsibility for the overall management and operations of the Funds, 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 (the “BlackRock-advised Funds”) 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”). Each Fund is included in the BlackRock Fund Complex referred to as the Exchange-Traded Fund Complex. Each Trustee also serves as a Director of iShares, Inc. and a Trustee of iShares Trust, and, as a result, oversees a total of 333 funds (as of October 31, 2016) within the Exchange-Traded Fund Complex. Mr. Lawton also serves as an Advisory Board Member for iShares, Inc. and iShares Trust with respect to 333 funds (as of October 31, 2016) within the Exchange-Traded Fund Complex. With the exception of Robert S. Kapito, Mark Wiedman and Benjamin Archibald, the address of each Trustee, Advisory Board Member and officer is c/o BlackRock, Inc., 400 Howard Street, San Francisco, CA 94105. The address of Mr. Kapito, Mr. Wiedman, and Mr. Archibald is c/o BlackRock, Inc., Park Avenue Plaza, 55 East 52^nd Street, New York, NY 10055. The Board has designated Cecilia H.

The Markit iBoxx USD Liquid High Yield Interest Rate Hedged Index is an unmanaged index that reflects the duration hedged performance of U.S. dollar-denominated high yield corporate debt.

The iShares Interest Rate Hedged High Yield Bond ETF (the “Fund”) seeks to mitigate the interest rate risk of a portfolio composed of U.S. dollar-denominated, high yield corporate bonds. The Fund is an actively managed exchange-traded fund that does not seek to replicate the performance of a specified index.

The Fund currently seeks to achieve its investment objective by investing a substantial portion of its assets in one underlying fund, the iShares iBoxx $ High Yield Corporate Bond ETF. The Fund attempts to mitigate the interest rate risk of the underlying fund by holding short positions in U.S. Treasury futures or interest rate swaps. For the 12-month reporting period ended October 31, 2016, the total return for the Fund was 4.73%, net of fees.

The Fund advanced for the reporting period, reflecting the strong performance of high-yield corporate bonds across all sectors. The most important contributing factor to Fund performance was strong investor demand for yield. With U.S. Treasury bond yields near historically low levels, investors shifted into higher-yielding segments of the bond market, and corporate bonds typically offer some of the highest yields. In addition, lower-quality corporate bonds attracted greater demand because of their yield advantage over higher-rated corporate securities.

Every sector of the Index contributed to performance for the reporting period. Industrial bonds, which represented approximately 85% of the Fund on average during the reporting period, contributed the most to Fund performance, led by the communications industry. Energy and basic materials bonds also contributed to performance, benefiting from rising commodities prices in the second half of the reporting period. Outside of the industrial sector, bonds issued by finance and electric utilities companies contributed to the Fund’s performance for the reporting period.

From a credit perspective, the Fund’s higher-risk, lower credit-quality bonds (Caa-rated) delivered a relatively large contribution to the Fund’s return despite being only 13% of the Fund on average for the reporting period.

The Fund’s interest rate hedging activity detracted from Fund performance for the reporting period. Hedging against interest rate risk can improve returns when bond yields rise, but it can be a drag on performance when bond yields decline, as was the case during the reporting period.

The Markit iBoxx USD Liquid Investment Grade Interest Rate Hedged Index is an unmanaged index that is designed to reflect the duration hedged performance of U.S. dollar-denominated investment-grade corporate debt.

The iShares Interest Rate Hedged Corporate Bond ETF (the “Fund”) seeks to mitigate the interest rate risk of a portfolio composed of U.S. dollar-denominated, investment-grade corporate bonds. The Fund is an actively managed exchange-traded fund that does not seek to replicate the performance of a specified index.

The Fund currently seeks to achieve its investment objective by investing a substantial portion of its assets in one underlying fund, the iShares iBoxx $ Investment Grade Corporate Bond ETF. The Fund attempts to mitigate the interest rate risk of the underlying fund by holding short positions in U.S. Treasury futures or interest rate swaps. For the 12-month reporting period ended October 31, 2016, the total return for the Fund was 2.70%, net of fees.

The Fund’s performance was largely driven by strong investor demand for yield in a low interest rate environment. Corporate bonds — which offer the highest yields in the U.S. bond market — outperformed all other sectors of the bond market. Higher-quality corporate bonds trailed high-yield corporate bonds, as the search for yield led investors to seek out riskier segments of the corporate bond market.

Every sector of the Fund contributed positively to performance for the reporting period. Industrial bonds, which represented approximately 65% of the Fund on average during the reporting period, contributed the most to Fund performance, led by the consumer-oriented and communications industries. Financial bonds, which represented approximately 33% of the Fund on average, also helped performance for the reporting period, with the banking and insurance industries contributing the most to performance. The utilities sector was a modest contributor due to its relatively small weighting in the Fund.

From a credit perspective, the Fund’s position in medium-quality bonds — those rated A and Baa, which represented approximately 84% of the Fund on average for the reporting period — delivered the largest contribution to the Fund’s return.

These financial statements relate only to the following funds (each, a “Fund,” and collectively, the “Funds”):

Currently each Fund seeks to achieve its investment objective by investing a substantial portion of its assets in an exchange-traded fund of iShares Trust (an “underlying fund”), an affiliate of the Funds. The financial statements and schedules of investments for the underlying funds can be found elsewhere in this report and should be read in conjunction with the Funds’ financial statements.

Security transactions are accounted for on trade date. Dividend income and capital gain distributions from underlying funds, if any, are recognized on the ex-dividend date. Interest income is accrued daily. Realized gains and losses on investment transactions are determined using the specific identification method.

Each Fund may lend its investment securities to approved borrowers, such as brokers, dealers and other financial institutions. The borrower pledges and maintains with the Fund collateral consisting of cash, an irrevocable letter of credit issued by a bank, or securities issued or guaranteed by the U.S. government. The initial collateral received by each Fund is required to have a value of at least 102% of the current value of the loaned securities for securities traded on U.S. exchanges and a value of at least 105% for all other securities. The collateral is maintained thereafter at a value equal to at least 100% of the current value of the securities on loan. The market value of the loaned securities is determined at the close of each business day of the Funds. Any additional required collateral is delivered to the Funds and any excess collateral is returned by the Funds on the next business day. During the term of the loan, each Fund is entitled to all distributions made on or in respect of the loaned securities but does not receive interest income on securities received as collateral. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within the standard time period for settlement of securities transactions.

The risks of securities lending include the risk that the borrower may not provide additional collateral when required or may not return the securities when due. To mitigate these risks, the Funds benefit from a borrower default indemnity provided by BlackRock. BlackRock’s indemnity allows for full replacement of securities lent. Each Fund could suffer a loss if the value of the investments purchased with cash collateral falls below the value of the cash collateral received.

as lender, would offset the market value of the collateral received against the market value of the securities loaned. The value of the collateral is typically greater than that of the market value of the securities loaned, leaving the lender with a net amount payable to the defaulting party. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against such a right of offset in the event of an MSLA counterparty’s bankruptcy or insolvency. Under the MSLA, the borrower can resell or re-pledge the loaned securities, and a Fund can reinvest cash collateral, or, upon an event of default, resell or re-pledge the collateral.

The following table is a summary of securities lending agreements which are subject to offset under an MSLA as of October 31, 2016:

For its investment advisory services to the iShares Interest Rate Hedged High Yield Bond ETF, BFA is entitled to an annual investment advisory fee of 0.65% based on the average daily net assets of the Fund. In addition, the Fund indirectly pays its pro rata share of fees and expenses attributable to its investments in other investment companies (“acquired fund fees and expenses”). BFA has contractually agreed to reduce its investment advisory fee for the Fund through February 28, 2022 so that the investment management fee is equal to the acquired fund fees and expenses that would have been experienced by the Fund related to its investments in the iShares iBoxx $ High Yield Corporate Bond ETF (“HYG”), after taking into account any fee waivers by HYG, plus 0.05%.

For its investment advisory services to the iShares Interest Rate Hedged Corporate Bond ETF, BFA is entitled to an annual investment advisory fee of 0.30% based on the average daily net assets of the Fund. In addition, the Fund indirectly pays acquired fund fees and expenses. BFA has contractually agreed to reduce its investment advisory fee for the Fund through February 28, 2022 so that the investment advisory fee is equal to the acquired fund fees and expenses that would have been experienced by the Fund related to its investments in the iShares iBoxx $ Investment Grade Corporate Bond ETF (“LQD”), after taking into account any fee waivers by LQD, plus 0.10%.

and from borrowers of securities, and less the collateral investment fees. The Funds retain a portion of securities lending income and remit the remaining portion to BTC as compensation for its services as securities lending agent.

For the year ended October 31, 2016, the total of securities lending agent services and collateral investment fees paid were as follows:

The PNC Financial Services Group, Inc. is the largest stockholder of BlackRock and is considered to be an affiliate of the Funds for 1940 Act purposes.

Purchases and sales of investments (excluding in-kind transactions and short-term investments) for the year ended October 31, 2016 were as follows:

In-kind transactions (see Note 4) for the year ended October 31, 2016 were as follows:

Each Fund may enter into short positions in interest rate swaps in an attempt to mitigate interest rate risk by economically hedging the value of fixed rate bonds, which may decrease when interest rates rise (interest rate risk). Interest rate swaps are agreements in which one party pays a stream of interest payments, either fixed or floating, for another party’s stream of interest payments, either fixed or floating, on the same notional amount for a specified period of time. Interest rate swaps are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). Swap agreements are privately negotiated in the over-the-counter market. Each Fund enters into centrally cleared interest rate swaps.

In a centrally cleared swap, immediately following execution of the swap agreement, the swap agreement is novated to a central counterparty (“CCP”) and the CCP becomes the Funds’ counterparty on the swap. Each Fund is required to interface with the CCP through a broker. Upon entering into a centrally cleared swap, each Fund is required to deposit initial margin with the broker in the form of cash or securities in an amount that varies depending on the size and risk profile of the particular swap. Securities deposited as initial margin are designated on the schedules of investments and cash deposited is recorded on the statements of assets and liabilities as cash pledged for centrally cleared swaps. The daily change in valuation of centrally cleared swaps is recorded as a receivable or payable for variation margin in the statements of assets and liabilities. Payments received from (paid to) the CCP, including at termination, are recorded as realized gain (loss) in the statements of operations.

Swap transactions involve, to varying degrees, elements of interest rate, credit and market risks in excess of the amounts recognized in the statements of assets and liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of the contractual terms in the agreements, and that there may be unfavorable changes in interest rates and/or market values associated with these transactions.

The following table shows the value of interest rate swaps held as of October 31, 2016 and the related locations in the statements of assets and liabilities, presented by risk exposure category:

The following table shows the realized and unrealized gains (losses) on interest rate swaps held during the year ended October 31, 2016 and the related locations in the statements of operations, presented by risk exposure category:

As of October 31, 2016, the following Funds had non-expiring capital loss carryforwards available to offset future realized capital gains as follows:

In our opinion, the accompanying statements of assets and liabilities, including the schedules of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of iShares Interest Rate Hedged High Yield Bond ETF and iShares Interest Rate Hedged Corporate Bond ETF (the “Funds”) at October 31, 2016, the results of each of their operations, the changes in each of their net assets and their financial highlights for each of the periods presented, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at October 31, 2016 by correspondence with the custodian, transfer agent and brokers, provide a reasonable basis for our opinion.

For the fiscal year ended October 31, 2016, the Funds hereby designate the following maximum amounts allowable as interest-related dividends eligible for exemption from U.S. withholding tax for nonresident aliens and foreign corporations:

Under Section 15(c) of the Investment Company Act of 1940 (the “1940 Act”), the Trust’s Board of Trustees (the “Board”), including a majority of Trustees who are not “interested persons” of the Trust (as that term is defined in the 1940 Act) (the “Independent Trustees”), is required annually to consider and approve the Investment Advisory Contract between the Trust and BFA (the “Advisory Contract”) on behalf of the Fund. The Independent Trustees requested, and BFA provided, such information as the Independent Trustees, with advice from independent counsel, deemed reasonably necessary to evaluate the Advisory Contract. A committee of all of the Independent Trustees (the “15(c) Committee”), with independent counsel, met with management on April 28, 2016 and May 9, 2016. At these meetings, the 15(c) Committee reviewed and discussed information provided in response to the 15(c) Committee’s initial requests, and requested certain additional information, which management agreed to provide. At a meeting held on May 17, 2016, management presented information to the Board relating to the continuance of the Advisory Contract, including information requested by the 15(c) Committee during its meetings. The Board, including the Independent Trustees, reviewed and discussed such information at length. The Independent Trustees requested from management certain additional information, which management agreed to provide. At a meeting held on June 21-23, 2016, the Board, including the Independent Trustees, reviewed the additional information provided by management in response to these requests. After extensive discussions, the Board, including all of the Independent Trustees, approved the continuance of the Advisory Contract for the Fund, based on a review of qualitative and quantitative information provided by BFA, including the additional information management provided at the request of the Independent Trustees. The Board noted its satisfaction with the extent and quality of information provided and its frequent interactions with management, as well as the detailed responses and other information provided by BFA. The Board also noted that the Board and BFA agreed to discuss potential enhancements and adjustments to the 15(c) process for the coming year. The Independent Trustees were advised by their independent counsel throughout the process, including about the legal standards applicable to their review. In approving the Advisory Contract for the Fund, the Board, including the Independent Trustees, considered the following factors, no one of which was controlling, and reached the following conclusions:

not otherwise be reasonable in Broadridge’s judgment, pure index institutional mutual funds, objectively selected by Broadridge as comprising the Fund’s applicable peer group pursuant to Broadridge’s proprietary ETF methodology (the “Peer Group”). The Board was provided with a detailed description of Broadridge’s proprietary ETF methodology used by Broadridge to determine the Fund’s Peer Group. The Board further noted that due to the limitations in providing comparable funds in the Peer Group, the statistical information provided in Broadridge’s report may or may not provide meaningful direct comparisons to the Fund in all instances.

The Board also noted that the investment advisory fee rate and overall expenses (net of waivers and reimbursements) for the Fund were higher than the median of the investment advisory fee rates and overall expenses (net of waivers and reimbursements) of the funds in its Peer Group, excluding iShares funds. The Board further noted that the Fund’s pricing reflects its interest rate hedging strategy, as compared to the competitor funds as determined by Broadridge, which are not interest rate hedged.

Based on this review, the other factors considered at the meeting, and their general knowledge of ETF pricing, the Board concluded that the investment advisory fee rate and expense level and the historical performance of the Fund supported the Board’s approval of the continuance of the Advisory Contract for the coming year.

Nature, Extent and Quality of Services Provided by BFA — Based on management’s representations, including information about recent and proposed enhancements to the iShares business, including with respect to capital markets support and analysis, product design and other services, the Board expected that there would be no diminution in the scope of services required of or provided by BFA under the Advisory Contract for the coming year as compared to the scope of services provided by BFA during prior years. In reviewing the scope of these services, the Board considered BFA’s investment philosophy and experience, noting that BFA and its affiliates have committed significant resources over time, including during the past year, to supporting the iShares funds and their shareholders. The Board also considered BFA’s compliance program and its compliance record with respect to the Fund. In that regard, the Board noted that BFA reports to the Board about portfolio management and compliance matters on a periodic basis in connection with regularly scheduled meetings of the Board, and on other occasions as necessary and appropriate, and has provided information and made appropriate officers available as needed to provide further assistance with these matters. The Board also reviewed the background and experience of the persons responsible for the day-to-day management of the Fund, as well as the resources available to them in managing the Fund. In addition to the above considerations, the Board reviewed and considered detailed presentations regarding BFA’s investment performance, investment and risk management processes and strategies provided at the June 21-23, 2016 meeting and throughout the previous year, and matters related to BFA’s portfolio compliance policies and procedures. The Board noted that the Fund had met its investment objective consistently since its inception date.

Based on review of this information, and the performance information discussed above, the Board concluded that the nature, extent and quality of services provided by BFA to the Fund under the Advisory Contract supported the Board’s approval of the continuance of the Advisory Contract for the coming year.

nature of the Fund’s advisory fee structure, and the Fund expenses borne by BFA under this arrangement. The Board noted that the investment advisory fee rate under the Advisory Contract for the Fund was generally higher than the investment advisory/management fee rates for certain of the Other Accounts (particularly institutional clients) and concluded that the differences appeared to be consistent with the factors discussed.

Other Benefits to BFA and/or its Affiliates — The Board reviewed the “fallout” benefits or ancillary revenue received by BFA and/or its affiliates in connection with the services provided to the Fund by BFA, such as payment of revenue to BTC, the Fund’s securities lending agent, for loaning portfolio securities (which was included in the profit margins reviewed by the Board pursuant to BFA’s profitability methodology), and payment of advisory fees and/or administration fees to BFA and BTC (or their affiliates) in connection with any investments by the Fund in other funds for which BFA (or its affiliates) provides investment advisory services and/or administration services. The Board noted that BFA generally does not use soft dollars or consider the value of research or other services that may be provided to BFA (including its affiliates) in selecting brokers for portfolio transactions for the Fund. The Board further noted that any portfolio transactions on behalf of the Fund placed through a BFA affiliate or purchased from an underwriting syndicate in which a BFA affiliate participates, are reported to the Board pursuant to Rule 17e-1 or Rule 10f-3, as applicable, under the 1940 Act. The Board concluded that any such ancillary benefits would not be disadvantageous to the Fund’s shareholders and thus would not alter the Board’s conclusion with respect to the appropriateness of approving the continuance of the Advisory Contract for the coming year.

Under Section 15(c) of the Investment Company Act of 1940 (the “1940 Act”), the Trust’s Board of Trustees (the “Board”), including a majority of Trustees who are not “interested persons” of the Trust (as that term is defined in the 1940 Act) (the “Independent Trustees”), is required annually to consider and approve the Investment Advisory Contract between the Trust and BFA (the “Advisory Contract”) on behalf of the Fund. The Independent Trustees requested, and BFA provided, such information as the Independent Trustees, with advice from independent counsel, deemed reasonably necessary to evaluate the Advisory Contract. A committee of all of the Independent Trustees (the “15(c) Committee”), with independent counsel, met with management on April 28, 2016 and May 9, 2016. At these meetings, the 15(c) Committee reviewed and discussed information provided in response to the 15(c) Committee’s initial requests, and requested certain additional information, which management agreed to provide.

The Board also noted that the investment advisory fee rate and overall expenses (net of waivers and reimbursements) for the Fund were higher than the median of the investment advisory fee rates and overall expenses (net of waivers and reimbursements) of the funds in its Peer Group, excluding iShares funds. The Board further noted that the Fund’s Peer Group contained only four comparison funds identified by Broadridge, excluding iShares funds.

Based on this review, the other factors considered at the meeting, and their general knowledge of ETF pricing, the Board concluded that the investment advisory fee rate and expense level and the historical performance of the Fund supported the Board’s approval of the continuance of the Advisory Contract for the coming year.

Nature, Extent and Quality of Services Provided by BFA — Based on management’s representations, including information about recent and proposed enhancements to the iShares business, including with respect to capital markets support and analysis, product design and other services, the Board expected that there would be no diminution in the scope of services required of or provided by BFA under the Advisory Contract for the coming year as compared to the scope of services provided by BFA during prior years.

The Board noted that the Fund had met its investment objective consistently since its inception date.

Based on review of this information, and the performance information discussed above, the Board concluded that the nature, extent and quality of services provided by BFA to the Fund under the Advisory Contract supported the Board’s approval of the continuance of the Advisory Contract for the coming year.

the pricing of services to institutional clients is typically based on a number of factors beyond the nature and extent of the specific services to be provided and often depends on the overall relationship between the client and its affiliates and the adviser and its affiliates. In addition, the Board considered the relative complexity and inherent risks and challenges of managing and providing other services to the Fund, as a publicly traded exchange traded fund, as compared to the Other Accounts that are institutional clients in light of differing regulatory requirements and client-imposed mandates. The Board also considered the “all-inclusive” nature of the Fund’s advisory fee structure, and the Fund expenses borne by BFA under this arrangement. The Board noted that the investment advisory fee rate under the Advisory Contract for the Fund was generally higher than the investment advisory/management fee rates for certain of the Other Accounts (particularly institutional clients) and concluded that the differences appeared to be consistent with the factors discussed.

Other Benefits to BFA and/or its Affiliates — The Board reviewed the “fallout” benefits or ancillary revenue received by BFA and/or its affiliates in connection with the services provided to the Fund by BFA, such as payment of revenue to BTC, the Fund’s securities lending agent, for loaning portfolio securities (which was included in the profit margins reviewed by the Board pursuant to BFA’s profitability methodology), and payment of advisory fees and/or administration fees to BFA and BTC (or their affiliates) in connection with any investments by the Fund in other funds for which BFA (or its affiliates) provides investment advisory services and/or administration services. The Board noted that BFA generally does not use soft dollars or consider the value of research or other services that may be provided to BFA (including its affiliates) in selecting brokers for portfolio transactions for the Fund. The Board further noted that any portfolio transactions on behalf of the Fund placed through a BFA affiliate or purchased from an underwriting syndicate in which a BFA affiliate participates, are reported to the Board pursuant to Rule 17e-1 or Rule 10f-3, as applicable, under the 1940 Act. The Board concluded that any such ancillary benefits would not be disadvantageous to the Fund’s shareholders and thus would not alter the Board’s conclusion with respect to the appropriateness of approving the continuance of the Advisory Contract for the coming year.

See notes to financial statements.

iShares Trust (the “Trust”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investment company. The Trust was established as a Delaware statutory trust pursuant to an Agreement and Declaration of Trust dated December 16, 1999.

These financial statements relate only to the following funds (each, a “Fund,” and collectively, the “Funds”):

The investment objective of each Fund is to seek investment results that correspond generally to the price and yield performance, before fees and expenses, of its underlying index. The investment adviser uses a “passive” or index approach to try to achieve each Fund’s investment objective.

The following significant accounting policies are consistently followed by the Funds in the preparation of their financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Each Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

Fair value pricing could result in a difference between the prices used to calculate a Fund’s NAV and the prices used by the Fund’s underlying index, which in turn could result in a difference between the Fund’s performance and the performance of the Fund’s underlying index.

Various inputs are used in determining the fair value of financial instruments. Inputs may be based on independent market data (“observable inputs”) or they may be internally developed (“unobservable inputs”). These inputs are categorized into a disclosure hierarchy consisting of three broad levels for financial reporting purposes. The level of a value determined for a financial instrument within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement in its entirety. The categorization of a value determined for a financial instrument within the hierarchy is based upon the pricing transparency of the instrument and is not necessarily an indication of the risk associated with investing in the instrument. The three levels of the fair value hierarchy are as follows:

Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. In accordance with the Trust’s policy, transfers between different levels of the fair value hierarchy are deemed to have occurred as of the beginning of the reporting period.

The following table summarizes the value of each of the Funds’ investments according to the fair value hierarchy as of February 29, 2016. The breakdown of each Fund’s investments into major categories is disclosed in its respective schedule of investments.

Each Fund may lend its investment securities to approved borrowers, such as brokers, dealers and other financial institutions. The borrower pledges and maintains with the Fund collateral consisting of cash, an irrevocable letter of credit issued by a bank, or securities issued or guaranteed by the U.S. government. The initial collateral received by each Fund is required to have a value of at least 102% of the current value of the loaned securities plus the interest accrued on such securities, if any, for securities traded on U.S. exchanges and a value of at least 105% for all other securities. The collateral is maintained thereafter at a value equal to at least 100% of the current value of the securities on loan plus accrued interest, if any. The market value of the loaned securities is determined at the close of each business day of the Funds. Any additional required collateral is delivered to the Funds and any excess collateral is returned by the Funds on the next business day. During the term of the loan, each Fund is entitled to all distributions made on or in respect of the loaned securities. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within the standard time period for settlement of securities transactions.

Any cash received as collateral for securities on loan may be reinvested in certain short-term instruments either directly on behalf of a fund or through one or more joint accounts or money market funds, including those managed by BlackRock Fund Advisors (“BFA”), the Funds’ investment adviser, or its affiliates. As of February 29, 2016, any securities on loan were collateralized by cash. The cash collateral received was invested in money market funds managed by BFA and is disclosed in the schedules of investments. The securities on loan for each Fund are also disclosed in its schedule of investments. The total value of any securities on loan as of February 29, 2016 and the total value of the related collateral are disclosed in the statements of assets and liabilities. Income earned by the Funds from securities lending is disclosed in the statements of operations.

The risks of securities lending include the risk that the borrower may not provide additional collateral when required or may not return the securities when due. To mitigate these risks, the Funds benefit from a borrower default indemnity provided by BlackRock, Inc. (“BlackRock”). BlackRock’s indemnity allows for full replacement of securities lent. Each Fund could suffer a loss if the value of the investments purchased with cash collateral falls below the value of the cash collateral received.

The following table is a summary of securities lending agreements which are subject to offset under an MSLA as of February 29, 2016:

For its investment advisory services to the iShares iBoxx $ High Yield Corporate Bond ETF, BFA is entitled to an annual investment advisory fee based on the Fund’s allocable portion of the aggregate of the average daily net assets of the Fund and certain other iShares funds, as follows:

For its investment advisory services to the iShares iBoxx $ Investment Grade Corporate Bond ETF, BFA is entitled to an annual investment advisory fee based on the Fund’s allocable portion of the aggregate of the average daily net assets of the Fund and certain other iShares funds, as follows:

Prior to July 1, 2015, for its investment advisory services to the iShares iBoxx $ Investment Grade Corporate Bond ETF, BFA was entitled to an annual investment advisory fee based on the Fund’s allocable portion of the aggregate of the average daily net assets of the Fund and certain other iShares funds, as follows:

The U.S. Securities and Exchange Commission has issued an exemptive order which permits BlackRock Institutional Trust Company, N.A. (“BTC”), an affiliate of BFA, to serve as securities lending agent for the Funds, subject to applicable conditions. As securities lending agent, BTC bears all operational costs directly related to securities lending. Each Fund is responsible for fees in connection with the investment of cash collateral received for securities on loan in a money market fund managed by BFA, however, BTC has agreed to reduce the amount of securities lending income it receives in order to effectively limit the collateral investment fees each Fund bears to an annual rate of 0.04% (the “collateral investment fees”). Securities lending income is equal to the total of income earned from the reinvestment of cash collateral, net of fees and other payments to and from borrowers of securities, and less the collateral investment fees. The Funds retain a portion of securities lending income and remit the remaining portion to BTC as compensation for its services as securities lending agent.

For the year ended February 29, 2016, the total of securities lending agent services and collateral investment fees paid were as follows:

Cross trading is the buying or selling of portfolio securities between funds to which BFA (or an affiliate) serves as investment adviser. At its regularly scheduled quarterly meetings, the Board reviews such transactions as of the most recent calendar quarter for compliance with the requirements and restrictions set forth by Rule 17a-7.

For the year ended February 29, 2016, transactions executed by the Funds pursuant to Rule 17a-7 under the 1940 Act were as follows:

Each Fund may invest its positive cash balances in certain money market funds managed by BFA or an affiliate. The income earned on these temporary cash investments is included in “Interest – affiliated” in the statements of operations.

The PNC Financial Services Group, Inc. is the largest stockholder of BlackRock and is considered to be an affiliate of the Funds for 1940 Act purposes.

Investments in issuers considered to be affiliates of the Funds (excluding money market funds) during the year ended February 29, 2016, for purposes of Section 2(a)(3) of the 1940 Act, were as follows:

Purchases and sales of investments (excluding in-kind transactions and short-term investments) for the year ended February 29, 2016 were as follows:

In-kind transactions (see Note 4) for the year ended February 29, 2016 were as follows:

From time to time, settlement of securities related to in-kind contributions or in-kind redemptions may be delayed. In such cases, securities related to in-kind contributions are reflected as “Due from custodian” and securities related to in-kind redemptions are reflected as “Securities related to in-kind transactions” in the statements of assets and liabilities.

BFA uses a “passive” or index approach to try to achieve each Fund’s investment objective following the securities included in its underlying index during upturns as well as downturns. BFA does not take steps to reduce market exposure or to lessen the effects of a declining market. Divergence from the underlying index and the composition of the portfolio is monitored by BFA.

Market risk arises mainly from uncertainty about future values of financial instruments influenced by price, currency and interest rate movements. It represents the potential loss each Fund may suffer through holding market positions in the face of market movements. Each Fund is exposed to market risk by virtue of its investment in fixed income instruments. The fair value of securities held by the Funds may decline due to general market conditions, economic trends or events that are not specifically related to the issuers of the securities including local, regional or global political, social or economic instability or to factors that affect a particular industry or group of industries. The extent of each Fund’s exposure to market risk is the market value of the investments held as shown in the Fund’s schedule of investments.

Each Fund invests a substantial amount of its assets in fixed-income securities. Changes in market interest rates or economic conditions, may affect the value and/or liquidity of such investments. Interest rate risk is the risk that prices of bonds and other fixed-income securities will decrease as interest rates rise and increase as interest rates fall. Securities with longer durations tend to be more sensitive to interest rate changes, usually making them more volatile than securities with shorter durations. Given the environment of historically low interest rates, each Fund may be subject to a greater risk of price losses if interest rates rise.

Credit risk is the risk that an issuer or guarantor of debt instruments or the counterparty to a financial transaction, including derivatives contracts, repurchase agreements or loans of portfolio securities, is unable or unwilling to make timely interest and/or principal payments or to otherwise honor its obligations. BFA and its affiliates manage counterparty credit risk by entering into transactions only with counterparties that they believe have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose the Funds to issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of each Fund’s exposure to credit and counterparty risks with respect to those financial assets is approximated by their value recorded in its statement of assets and liabilities.

The iShares $ iBoxx High Yield Corporate Bond ETF invests a substantial portion of its assets in high yield securities that are rated below investment-grade (including those bonds rated lower than “BBB- “ by Standard & Poor’s Ratings Services and Fitch or “Baa3” by Moody’s), or are unrated which 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 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 companies or by highly leveraged (indebted) companies, which are generally less able than more financially stable companies to make scheduled payments of interest and principal.

Management has analyzed tax laws and regulations and their application to the Funds as of February 29, 2016, inclusive of the open tax return years, and does not believe there are any uncertain tax positions that require recognition of a tax liability in the Funds’ financial statements.

In our opinion, the accompanying statements of assets and liabilities, including the schedules of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of iShares iBoxx $ High Yield Corporate Bond ETF and iShares iBoxx $ Investment Grade Corporate Bond ETF (the “Funds”) at February 29, 2016, the results of each of their operations, the changes in each of their net assets and their financial highlights for each of the periods presented, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at February 29, 2016 by correspondence with the custodian, transfer agent and brokers, provide a reasonable basis for our opinion.

This report is intended for the Funds’ shareholders. It may not be distributed to prospective investors unless it is preceded or accompanied by the current prospectus.

The iShares Funds are distributed by BlackRock Investments, LLC (together with its affiliates, “BlackRock”).

The inception date of the Fund was 7/22/15. The first day of secondary market trading was 7/23/15.

The Bloomberg Barclays U.S. Long Credit Interest Rate Swaps Hedged Index (formerly the Barclays U.S. Long Credit Interest Rate Swaps Hedged Index) is an unmanaged index that consists of the Bloomberg Barclays U.S. Long Credit Index plus interest rate swaps that intend to hedge the interest rate exposure of the existing Bloomberg Barclays U.S. Long Credit Index.

The iShares Interest Rate Hedged 10+ Year Credit Bond ETF (the “Fund”) seeks to mitigate the interest rate risk of a portfolio composed of investment-grade U.S. corporate bonds and U.S. dollar-denominated bonds, including those of non-U.S. corporations and governments, with remaining maturities greater than ten years. The Fund is an actively managed exchange-traded fund that does not seek to replicate the performance of a specified index.

The Fund currently seeks to achieve its investment objective by investing a substantial portion of its assets in one underlying fund, the iShares 10+ Year Credit Bond ETF. The Fund attempts to mitigate the interest rate risk of the underlying fund by holding short positions in U.S. Treasury futures or interest rate swaps. For the 12-month reporting period ended October 31, 2016, the total return for the Fund was 2.49%, net of fees.

The Fund’s performance was largely driven by strong investor demand for yield in a low interest rate environment, which narrowed the difference in yield between U.S. Treasuries and corporate bonds. Corporate bonds — which typically offer higher yields than U.S. Treasuries — outperformed all other sectors of the bond market. Higher-quality corporate bonds trailed high-yield bonds, as the search for yield led investors to seek out riskier segments of the corporate bond market.

Every sector of the Fund contributed positively to performance for the reporting period. Corporate bonds, which represented approximately 82% of the Fund on average during the reporting period, contributed the majority of the Fund’s return. Within the corporate sector, industrial bonds contributed the most to Fund performance, led by the consumer-oriented and communications industries. The Fund’s energy bonds also performed well as oil and gas prices rebounded in the second half of the reporting period. Financial bonds also helped Fund performance for the reporting period, with the banking and insurance industries contributing the most to performance.

Non-corporate credit securities also contributed to the Fund’s return for the reporting period. These securities tend to be higher quality than corporate bonds, and consequently offer lower yields.

From a credit quality perspective, the Fund’s position in medium-quality bonds — those rated A and Baa, which represented approximately 80% of the Fund on average for the reporting period — delivered the largest contribution to the Fund’s return.

Actual Expenses — The table provides information about actual account values and actual expenses. Annualized expense ratios reflect contractual and voluntary fee waivers, if any. To estimate the expenses that you paid on your account over the period, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number under the heading entitled “Expenses Paid During Period.”

Hypothetical Example for Comparison Purposes — The table also provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses. You may use this information to compare the ongoing costs of investing in your Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Centrally cleared short interest rate swaps outstanding as of October 31, 2016 were as follows:

Currently the Fund seeks to achieve its investment objective by investing a substantial portion of its assets in an exchange-traded fund of iShares Trust (an “underlying fund”), an affiliate of the Fund. The financial statements and schedules of investments for the underlying fund can be found elsewhere in this report and should be read in conjunction with the Fund’s financial statements.

Pursuant to the Trust’s organizational documents, the Fund’s officers and trustees are indemnified against certain liabilities that may arise out of the performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts with service providers that contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred.

The following significant accounting policies are consistently followed by the Fund in the preparation of its financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

The Fund’s investments are valued at fair value each day that the Fund’s listing exchange is open and, for financial reporting purposes, as of the report date should the reporting period end on a day that the Fund’s listing exchange is not open. U.S. GAAP defines fair value as the price a fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) provides oversight of the valuation of investments for the Fund. The investments of the Fund are valued pursuant to policies and procedures developed by the Global Valuation Committee and approved by the Board of Trustees of the Trust (the “Board”).

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgement exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The fair value hierarchy for the Fund’s investments is included in its schedule of investments.

Security transactions are accounted for on trade date. Dividend income and capital gain distributions from the Underlying Funds, if any, are recognized on the ex-dividend date. Interest income is accrued daily. Realized gains and losses on investment transactions are determined using the specific identification method.

Dividends and distributions paid by the Fund are recorded on the ex-dividend dates. Distributions are determined on a tax basis and may differ from net investment income and net realized capital gains for financial reporting purposes. Dividends and distributions are paid in U.S. dollars and cannot be automatically reinvested in additional shares of the Fund.

Pursuant to an Investment Advisory Agreement with the Trust, BlackRock Fund Advisors (“BFA”) manages the investment of the Fund’s assets. BFA is a California corporation indirectly owned by BlackRock, Inc. (“BlackRock”). Under the Investment Advisory Agreement, BFA is responsible for substantially all expenses of the Fund, except interest, taxes, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution fees, litigation expenses and any extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to an annual investment advisory fee of 0.35% based on the average daily net assets of the Fund. In addition, the Fund indirectly pays its pro rata share of fees and expenses attributable to its investments in other investment companies (“acquired fund fees and expenses”). BFA has contractually agreed to reduce its investment advisory fee for the Fund through February 28, 2022 so that the investment advisory fee is equal to the acquired fund fees and expenses that would be been experienced by the Fund related to its investments in the iShares 10+ Year Credit Bond ETF (“CLY”), after taking into account any fee waivers by CLY, plus 0.10%.

BlackRock Investments, LLC, an affiliate of BFA, is the distributor for the Fund. Pursuant to the distribution agreement, BFA is responsible for any fees or expenses for distribution services provided to the Fund.

The Fund may invest its positive cash balances in certain money market funds managed by BFA or an affiliate. The income earned on these temporary cash investments is included in “Dividends – affiliated” in the statement of operations.

The PNC Financial Services Group, Inc. is the largest stockholder of BlackRock and is considered to be an affiliate of the Fund for 1940 Act purposes.

Certain trustees and officers of the Trust are also officers of BlackRock Institutional Trust Company, N.A. and/or BFA.

Purchases and sales of investments (excluding in-kind transactions and short-term investments) for the year ended October 31, 2016, were $611,569 and $1,120,948, respectively.

In-kind purchases and sales (see Note 4) for the year ended October 31, 2016, were $1,129,399 and $1,075,051, respectively.

Capital shares are issued and redeemed by the Fund only in aggregations of a specified number of shares or multiples thereof (“Creation Units”) at NAV. Except when aggregated in Creation Units, shares of the Fund are not redeemable. Transactions in capital shares for the Fund are disclosed in detail in the statements of changes in net assets.

and a redemption transaction fee directly to State Street Bank and Trust Company, the Trust’s administrator, to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units, including Creation Units for cash. Investors transacting in Creation Units for cash may also pay an additional variable charge to compensate the relevant fund for certain transaction costs (i.e., stamp taxes, taxes on currency or other financial transactions, and brokerage costs) and market impact expenses relating to investing in portfolio securities. Such variable charges, if any, are included in “Proceeds from shares sold” in the statement of changes in net assets.

The Fund may enter into short positions in interest rate swaps in an attempt to mitigate interest rate risk by economically hedging the value of fixed rate bonds, which may decrease when interest rates rise (interest rate risk). Interest rate swaps are agreements in which one party pays a stream of interest payments, either fixed or floating, for another party’s stream of interest payments, either fixed or floating, on the same notional amount for a specified period of time. Interest rate swaps are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). Swap agreements are privately negotiated in the over-the-counter market. The Fund enters into centrally cleared interest rate swaps.

In a centrally cleared swap, immediately following execution of the swap agreement, the swap agreement is novated to a central counterparty (“CCP”) and the CCP becomes the Fund’s counterparty on the swap. The Fund is required to interface with the CCP through a broker. Upon entering into a centrally cleared swap, the Fund is required to deposit initial margin with the broker in the form of cash or securities in an amount that varies depending on the size and risk profile of the particular swap. Securities deposited as initial margin are designated on the schedule of investments and cash deposited is recorded on the statement of assets and liabilities as cash pledged for centrally cleared swaps. The daily change in valuation of centrally cleared swaps is recorded as a receivable or payable for variation margin in the statement of assets and liabilities. Payments received from (paid to) the CCP, including at termination, are recorded as realized gain (loss) in the statement of operations.

Swap transactions involve, to varying degrees, elements of interest rate, credit and market risks in excess of the amounts recognized in the statement of assets and liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of the contractual terms in the agreements, and that there may be unfavorable changes in interest rates and/or market values associated with these transactions.

The following table shows the value of interest rate swaps held by the Fund as of October 31, 2016 and the related locations in the statement of assets and liabilities, presented by risk exposure category:

The following table shows the realized and unrealized gains (losses) on interest rate swaps held by the Fund during the year ended October 31, 2016 and the related locations in the statement of operations, presented by risk exposure category:

For the year ended October 31, 2016, the average quarter-end notional amount of open interest rate swaps for the Fund (where the Fund pays the fixed rate), was $6,386,000.

In the normal course of business, the Fund’s investment activities expose it to various types of risk associated with the financial instruments and markets in which it invests. The significant types of financial risks the Fund is exposed to include market risk and credit risk. The Fund’s prospectus provides details of these and other types of risk.

A diversified portfolio, where this is appropriate and consistent with a fund’s objectives, minimizes the risk that a price change of a particular investment will have a material impact on the NAV of a fund. The investment concentrations within the Fund’s portfolio are disclosed in its schedule of investments.

The Fund is treated as an entity separate from the Trust’s other funds for federal income tax purposes. It is the policy of the Fund to qualify as a regulated investment company by complying with the provisions applicable to regulated investment companies, as defined under Subchapter M of the Internal Revenue Code of 1986, as amended, and to annually distribute substantially all of its ordinary income and any net capital gains (taking into account any capital loss carryforwards) sufficient to relieve it from all, or substantially all, federal income and excise taxes. Accordingly, no provision for federal income taxes is required.

U.S. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or NAV per share. The following permanent differences as of October 31, 2016, attributable to the accounting for swap agreements and realized gains (losses) from in-kind redemptions, were reclassified to the following accounts:

The tax character of distributions paid during the years ended October 31, 2016 and October 31, 2015 was as follows:

As of October 31, 2016, the tax components of accumulated net earnings (losses) were as follows:

As of October 31, 2016, the Fund had non-expiring capital loss carryforwards in amount of $837,484 available to offset future realized capital gains.

Management has analyzed tax laws and regulations and their application to the Fund as of October 31, 2016, inclusive of the open tax return years, and does not believe there are any uncertain tax positions that require recognition of a tax liability in the Fund’s financial statements.

Management has evaluated the impact of all subsequent events on the Fund through the date the financial statements were available to be issued and has determined that there were no subsequent events requiring adjustment or disclosure in the financial statements.

In our opinion, the accompanying statement of assets and liabilities, including the schedule of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of iShares Interest Rate Hedged 10+ Year Credit Bond ETF (the “Fund”) at October 31, 2016, the results of its operations, the changes in its net assets and its financial highlights for each of the periods presented, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at October 31, 2016 by correspondence with the custodian, transfer agent and brokers, provide a reasonable basis for our opinion.

For the fiscal year ended October 31, 2016, the Fund hereby designates $194,233 as the maximum amount allowable as interest-related dividends eligible for exemption from U.S. withholding tax for nonresident aliens and foreign corporations.

Under Section 15(c) of the Investment Company Act of 1940 (the “1940 Act”), the Trust’s Board of Trustees (the “Board”), including a majority of Trustees who are not “interested persons” of the Trust (as that term is defined in the 1940 Act) (the “Independent Trustees”), is required annually to consider and approve the Investment Advisory Contract between the Trust and BFA (the “Advisory Contract”) on behalf of the Fund. The Independent Trustees requested, and BFA provided, such information as the Independent Trustees, with advice from independent counsel, deemed reasonably necessary to evaluate the Advisory Contract. A committee of all of the Independent Trustees (the “15(c) Committee”), with independent counsel, met with management on April 28, 2016 and May 9, 2016. At these meetings, the 15(c) Committee reviewed and discussed information provided in response to the 15(c) Committee’s initial requests, and requested certain additional information, which management agreed to provide. At a meeting held on May 17, 2016, management presented information to the Board relating to the continuance of the Advisory Contract, including information requested by the 15(c) Committee during its meetings. The Board, including the Independent Trustees, reviewed and discussed such information at length. The Independent Trustees requested from management certain additional information, which management agreed to provide. At a meeting held on June 21-23, 2016, the Board, including the Independent Trustees, reviewed the additional information provided by management in response to these requests. After extensive discussions, the Board, including all of the Independent Trustees, approved the continuance of the Advisory Contract for the Fund, based on a review of qualitative and quantitative information provided by BFA, including the additional information management provided at the request of the Independent Trustees. The Board noted its satisfaction with the extent and quality of information provided and its frequent interactions with management, as well as the detailed responses and other information provided by BFA. The Board also noted that the Board and BFA agreed to discuss potential enhancements and adjustments to the 15(c) process for the coming year. The Independent Trustees were advised by their independent counsel throughout the process, including about the legal standards applicable to their review. In approving the Advisory Contract for the Fund, the Board, including the Independent Trustees, considered the following factors, no one of which was controlling, and reached the following conclusions:

reimbursements) of the funds in its Peer Group, excluding iShares funds. The Board further noted that the Fund’s Peer Group contained only four comparison funds identified by Broadridge, excluding iShares funds.

Based on this review, the other factors considered at the meeting, and their general knowledge of ETF pricing, the Board concluded that the investment advisory fee rate and expense level and the historical performance of the Fund supported the Board’s approval of the continuance of the Advisory Contract for the coming year.

Nature, Extent and Quality of Services Provided by BFA — Based on management’s representations, including information about recent and proposed enhancements to the iShares business, including with respect to capital markets support and analysis, product design and other services, the Board expected that there would be no diminution in the scope of services required of or provided by BFA under the Advisory Contract for the coming year as compared to the scope of services provided by BFA during prior years. In reviewing the scope of these services, the Board considered BFA’s investment philosophy and experience, noting that BFA and its affiliates have committed significant resources over time, including during the past year, to supporting the iShares funds and their shareholders. The Board also considered BFA’s compliance program and its compliance record with respect to the Fund. In that regard, the Board noted that BFA reports to the Board about portfolio management and compliance matters on a periodic basis in connection with regularly scheduled meetings of the Board, and on other occasions as necessary and appropriate, and has provided information and made appropriate officers available as needed to provide further assistance with these matters. The Board also reviewed the background and experience of the persons responsible for the day-to-day management of the Fund, as well as the resources available to them in managing the Fund. In addition to the above considerations, the Board reviewed and considered detailed presentations regarding BFA’s investment performance, investment and risk management processes and strategies provided at the June 21-23, 2016 meeting and throughout the previous year, and matters related to BFA’s portfolio compliance policies and procedures. The Board noted that the Fund had met its investment objective consistently since its inception date.

Based on review of this information, and the performance information discussed above, the Board concluded that the nature, extent and quality of services provided by BFA to the Fund under the Advisory Contract supported the Board’s approval of the continuance of the Advisory Contract for the coming year.

ancillary revenue with management, including the revenues to BTC from securities lending by the Fund. The Board also discussed BFA’s profit margin as reflected in the Fund’s profitability analysis and reviewed information regarding potential economies of scale (as discussed below). Based on this review, the Board concluded that the profits realized by BFA and its affiliates under the Advisory Contract and from other relationships between the Fund and BFA and/or its affiliates, if any, were within a reasonable range in light of the factors considered.

Fees and Services Provided for Other Comparable Funds/Accounts Managed by BFA and its Affiliates — The Board received and considered information regarding the investment advisory/management fee rates for other funds/accounts in the U.S. for which BFA (or its affiliates) provides investment advisory/management services, including open-end funds registered under the 1940 Act (including sub-advised funds), collective trust funds, and institutional separate accounts (together, the “Other Accounts”), and acknowledged BFA’s assertion that the iShares funds are fundamentally different investment vehicles from the Other Accounts. The Board noted that BFA and its affiliates do not manage Other Accounts with a similar investment strategy or investment mandate as the Fund. The Board further noted that BFA provided the Board with detailed information regarding how the Other Accounts (particularly institutional clients) generally differ from the Fund, including in terms of the different and generally more extensive services provided to the Fund, as well as other significant differences. In that regard, the Board considered that the pricing of services to institutional clients is typically based on a number of factors beyond the nature and extent of the specific services to be provided and often depends on the overall relationship between the client and its affiliates and the adviser and its affiliates. In addition, the Board considered the relative complexity and inherent risks and challenges of managing and providing other services to the Fund, as a publicly traded exchange traded fund, as compared to the Other Accounts that are institutional clients in light of differing regulatory requirements and client-imposed mandates. The Board also considered the “all-inclusive” nature of the Fund’s advisory fee structure, and the Fund expenses borne by BFA under this arrangement. The Board noted that the investment advisory fee rate under the Advisory Contract for the Fund was generally higher than the investment advisory/management fee rates for certain of the Other Accounts (particularly institutional clients) and concluded that the differences appeared to be consistent with the factors discussed.

connection with any investments by the Fund in other funds for which BFA (or its affiliates) provides investment advisory services and/or administration services. The Board noted that BFA generally does not use soft dollars or consider the value of research or other services that may be provided to BFA (including its affiliates) in selecting brokers for portfolio transactions for the Fund. The Board further noted that any portfolio transactions on behalf of the Fund placed through a BFA affiliate or purchased from an underwriting syndicate in which a BFA affiliate participates, are reported to the Board pursuant to Rule 17e-1 or Rule 10f-3, as applicable, under the 1940 Act. The Board concluded that any such ancillary benefits would not be disadvantageous to the Fund’s shareholders and thus would not alter the Board’s conclusion with respect to the appropriateness of approving the continuance of the Advisory Contract for the coming year.

The amounts and sources of distributions reported are estimates and are provided pursuant to regulatory requirements and are not being provided for tax reporting purposes. The actual amounts and sources for tax reporting purposes will depend upon the Fund’s investment experience during the year and may be subject to changes based on the tax regulations. Shareholders will receive a Form 1099-DIV each calendar year that will inform them how to report these distributions for federal income tax purposes.

The following information shows the frequency of distributions of premiums and discounts for the Fund. The information shown for the Fund is for five calendar years (or from the inception date of the Fund if less than five years) through the date of the most recent calendar quarter-end. The specific periods covered for the Fund are disclosed in the table for the Fund.

The registered investment companies advised by BFA or its affiliates (the “BlackRock-advised Funds”) are organized into one complex of closed-end funds, two complexes of open-end funds and one complex of 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. and a Trustee of iShares Trust, and, as a result, oversees a total of 333 funds (as of October 31, 2016) within the Exchange-Traded Fund Complex. Mr. Lawton also serves as an Advisory Board Member for iShares, Inc. and iShares Trust with respect to 333 funds (as of October 31, 2016) within the Exchange-Traded Fund Complex. With the exception of Robert S. Kapito, Mark Wiedman and Benjamin Archibald, the address of each Trustee, Advisory Board Member and officer is c/o BlackRock, Inc., 400 Howard Street, San Francisco, CA 94105. The address of Mr. Kapito, Mr. Wiedman, and Mr. Archibald is c/o BlackRock, Inc., Park Avenue Plaza, 55 East 52^nd Street, New York, NY 10055. The Board has designated Cecilia H. Herbert as its Independent Board Chair.

See notes to financial statements.

The investment objective of the Fund is to seek investment results that correspond generally to the price and yield performance, before fees and expenses, of its underlying index. The investment adviser uses a “passive” or index approach to try to achieve the Fund’s investment objective.

Fair value pricing could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Fund’s underlying index, which in turn could result in a difference between the Fund’s performance and the performance of the Fund’s underlying index.

The following table summarizes the value of each of the Fund’s investments according to the fair value hierarchy as of February 29, 2016. The breakdown of the Fund’s investments into major categories is disclosed in its schedule of investments.

The Fund may lend its investment securities to approved borrowers, such as brokers, dealers and other financial institutions. The borrower pledges and maintains with the Fund collateral consisting of cash, an irrevocable letter of credit issued by a bank, or securities issued or guaranteed by the U.S. government. The initial collateral received by the Fund is required to have a value of at least 102% of the current value of the loaned securities plus the interest accrued on such securities, if any, for securities traded on U.S. exchanges and a value of at least 105% for all other securities. The collateral is maintained thereafter at a value equal to at least 100% of the current value of the securities on loan plus accrued interest, if any. The market value of the loaned securities is determined at the close of each business day of the Fund. Any additional required collateral is delivered to the Fund and any excess collateral is returned by the Fund on the next business day. During the term of the loan, the Fund is entitled to all distributions made on or in respect of the loaned securities. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within the standard time period for settlement of securities transactions.

Any cash received as collateral for securities on loan may be reinvested in certain short-term instruments either directly on behalf of a fund or through one or more joint accounts or money market funds, including those managed by BlackRock Fund Advisors (“BFA”), the Fund’s investment adviser, or its affiliates. As of February 29, 2016, any securities on loan were collateralized by cash. The cash collateral received was invested in money market funds managed by BFA and is disclosed in the schedule of investments. The securities on loan for the Fund are also disclosed in its schedule of investments. The total value of any securities on loan as of February 29, 2016 and the total value of the related collateral are disclosed in the statement of assets and liabilities. Income earned by the Fund from securities lending is disclosed in the statement of operations.

BlackRock, Inc. (“BlackRock”). BlackRock’s indemnity allows for full replacement of securities lent. The Fund could suffer a loss if the value of the investments purchased with cash collateral falls below the value of the cash collateral received.

Securities lending transactions are entered into by the Fund under Master Securities Lending Agreements (“MSLA”) which provide the right, in the event of default (including bankruptcy or insolvency) for the non-defaulting party to liquidate the collateral and calculate a net exposure to the defaulting party or request additional collateral. In the event that a borrower defaults, the Fund, as lender, would offset the market value of the collateral received against the market value of the securities loaned. The value of the collateral is typically greater than that of the market value of the securities loaned, leaving the lender with a net amount payable to the defaulting party. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against such a right of offset in the event of an MSLA counterparty’s bankruptcy or insolvency. Under the MSLA, the borrower can resell or re-pledge the loaned securities, and the Fund can reinvest cash collateral, or, upon an event of default, resell or re-pledge the collateral.

The following table is a summary of securities lending agreements which are subject to offset under an MSLA as of February 29, 2016:

Pursuant to an Investment Advisory Agreement with the Trust, BFA manages the investment of the Fund’s assets. BFA is a California corporation indirectly owned by BlackRock. Under the Investment Advisory Agreement, BFA is responsible for substantially all expenses of the Fund, except interest, taxes, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution fees, litigation expenses and any extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to an annual investment advisory fee of 0.20% based on the average daily net assets of the Fund.

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% (the “collateral investment fees”). Securities lending income is equal to the total of income earned from the reinvestment of cash collateral, net of fees and other payments to and from borrowers of securities, and less the collateral investment fees. The Fund retains a portion of securities lending income and remits the remaining portion to BTC as compensation for its services as securities lending agent.

Pursuant to a securities lending agreement, the Fund retains 80% of securities lending income and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees. In addition, commencing the business day following the date that the aggregate securities lending income plus the collateral investment fees generated across all 1940 Act iShares exchange-traded funds (the “iShares ETF Complex”) in a given calendar year exceeds the aggregate securities lending income generated across the iShares ETF Complex in the calendar year 2013, the Fund, pursuant to a securities lending agreement, will retain for the remainder of that calendar year 85% of securities lending income and the amount retained can never be less than 70% of the total of securities lending income plus the collateral investment fees.

For the year ended February 29, 2016, the Fund paid to BTC securities lending agent services and collateral investment fees in the amount of $43,685.

For the year ended February 29, 2016, the purchase and sales transactions executed by the Fund pursuant to Rule 17a-7 under the 1940 Act were $320,710 and $1,283,829, respectively.

The Fund may invest its positive cash balances in certain money market funds managed by BFA or an affiliate. The income earned on these temporary cash investments is included in “Interest – affiliated” in the statement of operations.

The PNC Financial Services Group, Inc. is the largest stockholder of BlackRock and is considered an affiliate of the Fund for 1940 Act purposes.

Investments in issuers considered to be affiliates of the Fund (excluding money market funds) during the year ended February 29, 2016 , for purposes of Section 2(a)(3) of the 1940 Act, were as follows:

Purchases and sales of investments (excluding in-kind transactions and short-term investments) for the year ended February 29, 2016 were as follows:

In-kind transactions (see Note 4) for the year ended February 29, 2016 were as follows:

BFA uses a “passive” or index approach to try to achieve the Fund’s investment objective following the securities included in its underlying index during upturns as well as downturns. BFA does not take steps to reduce market exposure or to lessen the effects of a declining market. Divergence from the underlying index and the composition of the portfolio is monitored by BFA.

Market risk arises mainly from uncertainty about future values of financial instruments influenced by price, currency and interest rate movements. It represents the potential loss the Fund may suffer through holding market positions in the face of market movements. The Fund is exposed to market risk by virtue of its investment in fixed income instruments. The fair value of securities held by the Fund may decline due to general market conditions, economic trends or events that are not specifically related to the issuers of the securities including local, regional or global political, social or economic instability or to factors that affect a particular industry or group of industries. The extent of the Fund’s exposure to market risk is the market value of the investments held as shown in the Fund’s schedule of investments.

A diversified portfolio, where this is appropriate and consistent with a fund’s objectives, minimizes the risk that a price change of a particular investment will have a material impact on the NAV of a fund. The investment concentrations within the Fund’s portfolio are disclosed in its schedule of investments.

The Fund invests a substantial amount of its assets in securities of non-U.S. issuers that trade in non-U.S. markets. This involves certain considerations and risks not typically associated with securities of U.S. issuers. Such risks include, but are not limited to: generally less liquid and less efficient securities markets; generally greater price volatility; exchange rate fluctuations and exchange controls; imposition of restrictions on the expatriation of funds or other assets of the Fund; less publicly available information about issuers; the imposition of withholding or other taxes; higher transaction and custody costs; settlement delays and risk of loss attendant in settlement procedures; difficulties in enforcing contractual obligations; less regulation of securities markets; different accounting, disclosure and reporting requirements; more substantial governmental involvement in the economy; higher inflation rates; greater social, economic and political uncertainties; the risk of nationalization or expropriation of assets; and the risk of war. These risks are heightened for investments in issuers from countries with less developed markets.

The Fund invests a substantial amount of its assets in fixed-income securities. Changes in market interest rates or economic conditions, may affect the value and/or liquidity of such investments. Interest rate risk is the risk that prices of bonds and other fixed-income securities will decrease as interest rates rise and increase as interest rates fall. Securities with longer durations tend to be more sensitive to interest rate changes, usually making them more volatile than securities with shorter durations. Given the environment of historically low interest rates, the Fund may be subject to a greater risk of price losses if interest rates rise.

Credit risk is the risk that an issuer or guarantor of debt instruments or the counterparty to a financial transaction, including derivatives contracts, repurchase agreements or loans of portfolio securities, is unable or unwilling to make timely interest and/or principal payments or to otherwise honor its obligations. BFA and its affiliates manage counterparty credit risk by entering into transactions only with counterparties that they believe have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose the Fund to issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of the Fund’s exposure to credit and counterparty risks with respect to those financial assets is approximated by their value recorded in its statement of assets and liabilities.

The tax character of distributions paid during the years ended February 29, 2016 and February 28, 2015 was as follows:

As of February 29, 2016, the tax components of accumulated net earnings (losses) were as follows:

As of February 29, 2016, the Fund had non-expiring capital loss carryforwards in the amount of $5,025,605 available to offset future realized capital gains.

As of February 29, 2016, the cost of investments for federal income tax purposes was $876,133,033. Net unrealized depreciation was $45,682,458, of which $6,463,875 represented gross unrealized appreciation on securities and $52,146,333 represented gross unrealized depreciation on securities.

Management has analyzed tax laws and regulations and their application to the Fund as of February 29, 2016, inclusive of the open tax return years, and does not believe there are any uncertain tax positions that require recognition of a tax liability in the Fund’s financial statements.

In our opinion, the accompanying statement of assets and liabilities, including the schedule of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of iShares 10+ Year Credit Bond ETF (the “Fund”) at February 29, 2016, the results of its operations, the changes in its net assets and its financial highlights for each of the periods presented, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at February 29, 2016 by correspondence with the custodian, transfer agent and brokers, provide a reasonable basis for our opinion.

Global investment-grade bonds posted positive returns in U.S. dollar terms for the 12-month period ended October 31, 2016 (the “reporting period”). The Bloomberg Barclays Global Aggregate Index returned 5.59% for the reporting period.

High-quality bonds benefited from solid investor demand, as generally poor global economic growth, low inflation, and stimulative monetary policies meant bond yields in many countries fell to record low, negative levels. Returns in U.S. dollar terms were mixed, however, reflecting the varied performance of the dollar relative to other developed market currencies.

In terms of growth, the U.S. economy improved over the course of the reporting period, expanding at a 0.8% annual rate in the first quarter of 2016 before reaching a 2.9% annual growth rate in the third quarter. Meanwhile, growth in much of the rest of the developed world was barely positive. The U.K. and Eurozone expanded by 0.5% and 0.3%, respectively, in the third quarter of 2016. Similarly, Australia and Japan grew by 0.5% and 0.2%, respectively, in the second quarter of 2016, the latest period for which data were available. Meanwhile, the Chinese economy grew at an annual rate of 6.7% in the third quarter of 2016; however, that was down from 6.9% a year earlier, which was the slowest growth since 1990.

Modest global growth meant inflation remained low. In the U.S., U.K., and the Eurozone, consumer prices increased over the course of the reporting period, reaching the highest levels since 2014, but remained at just 1.6%, 0.9%, and 0.5%, respectively, for the 12 months ended October 2016. In Japan, however, consumer prices were nearly unchanged, gaining by 0.1% for the same period.

To encourage growth and guard against deflation, many central banks around the world took further stimulus measures. Central banks from the U.K., Japan, Eurozone, and Australia all cut interest rates during the period to historic lows. One notable exception was the United States, where the U.S. Federal Reserve Bank (the “Fed”) raised rates in December 2015 for the first time in almost seven years.

Against that backdrop, Japanese long-term bond yields turned negative in early 2016, while bond yields in the Eurozone reached a record low of -0.47% in September 2016; similarly, German and French bonds set their all-time low negative yields in July 2016. The U.S., U.K. and Australia also saw long-term government bond yields reach historic lows during the reporting period, but their yields remained positive.

From a sector perspective, global Treasury bonds performed best, reflecting the sharp decline in long-term bond yields during the period. Other government-related securities also performed well, followed by investment-grade corporate bonds.

In terms of currency effects, the U.S. dollar appreciated by approximately 21% relative to the British pound, and 7% against the Chinese yuan for the reporting period. The U.S. dollar was little changed against the euro and Swiss franc. The Japanese yen and Australian dollar gained 13% and 6%, respectively, against the U.S. dollar. The U.S. dollar’s mixed performance reflects differences in expectations for economic growth and monetary policies between the U.S. and other regions.

On a country basis, U.K. bonds were the strongest performers among developed countries in local currency terms, but performed the worst in U.S. dollar terms. Benefiting from the strength of the yen and positive local currency returns, Japanese bonds performed the best in U.S. dollar terms. Australian bonds also performed very well in both Australian and U.S. dollar terms.

The inception date of the Fund was 7/22/15. The first day of secondary market trading was 7/23/15.

The J.P. Morgan EMBI Global Core Swap Hedged Index is an unmanaged index that consists of the J.P. Morgan EMBI^SMGlobal Core Index plus interest rate swaps that intend to hedge the interest rate exposure of the J.P. Morgan EMBI^SMGlobal Core Index.

The iShares Interest Rate Hedged Emerging Markets Bond ETF (the “Fund”) seeks to mitigate the interest rate risk of a portfolio composed of U.S. dollar-denominated, emerging market bonds. The Fund is an actively managed exchange-traded fund that does not seek to replicate the performance of a specified index.

The Fund currently seeks to achieve its investment objective by investing a substantial portion of its assets in one underlying fund, the iShares J.P. Morgan USD Emerging Markets Bond ETF. The Fund attempts to mitigate the interest rate risk of the underlying fund by holding short positions in U.S. Treasury futures or interest rate swaps. For the 12-month reporting period ended October 31, 2016, the total return for the Fund was 7.49%, net of fees.

The Fund generated a positive return for the reporting period as strong investor demand for yield coupled with modest global growth and low interest rates benefited the Fund’s performance.

The Fund’s Latin American bonds, which represented approximately 35% of the Fund on average during the reporting period, contributed the most to Index performance, led by Venezuela, Brazil, and Argentina. Venezuelan securities carried yields significantly higher than the Fund as a whole because the economic crisis affecting the country increased the likelihood of a bond default. Demand for those higher yields, along with investor belief that the recovery value of the bonds in default would exceed prevailing prices, helped Venezuelan securities during the reporting period. Brazilian bonds benefited from the resolution of impeachment proceedings against Brazil’s president and the initiation of much-anticipated financial reform. Argentina issued bonds for the first time in 15 years, attracting strong demand after resolving a lengthy standoff with creditors over a past debt default.

Emerging market bonds from Eastern Europe and Asia also made significant contributions to the Fund’s return, led by the Russian Federation and Indonesia, respectively. Africa and the Middle East also contributed to performance for the reporting period.

By maturity, longer-term bonds contributed to the Fund’s performance the most due to their higher yields. From a credit perspective, lower-quality bonds outperformed higher-rated securities, reflecting strong investor demand for yield.

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including brokerage commissions on purchases and sales of fund shares and (2) ongoing costs, including management fees and other fund expenses. The expense example, which is based on an investment of $1,000 invested on May 1, 2016 and held through October 31, 2016, is intended to help you understand your ongoing costs (in dollars and cents) of investing in the Fund and to compare these costs with the ongoing costs of investing in other funds.

Actual Expenses — The table provides information about actual account values and actual expenses. Annualized expense ratios reflect contractual and voluntary fee waivers, if any. To estimate the expenses that you paid on your account over the period, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number corresponding to your Fund under the heading entitled “Expenses Paid During Period.”

Hypothetical Example for Comparison Purposes — The table also provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses. You may use this information to compare the ongoing costs of investing in your Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Centrally cleared short interest rate swaps outstanding as of October 31, 2016 were as follows:

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgement exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The fair value hierarchy for the Fund’s investments is included in its schedule of investments.

The Fund may lend its investment securities to approved borrowers, such as brokers, dealers and other financial institutions. The borrower pledges and maintains with the Fund collateral consisting of cash, an irrevocable letter of credit issued by a bank, or securities issued or guaranteed by the U.S. government. The initial collateral received by the Fund is required to have a value of at least 102% of the current value of the loaned securities for securities traded on U.S. exchanges and a value of at least 105% for all other securities. The collateral is maintained thereafter at a value equal to at least 100% of the current value of the securities on loan. The market value of the loaned securities is determined at the close of each business day of the Fund. Any additional required collateral is delivered to the Fund and any excess collateral is returned by the Fund on the next business day. During the term of the loan, the Fund is entitled to all distributions made on or in respect of the loaned securities but does not receive interest income on securities received as collateral. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within the standard time period for settlement of securities transactions.

On October 11, 2016, BlackRock, Inc. (“BlackRock”) implemented changes required by amendments to Rule 2a-7 under the 1940 Act, which governs the operations of U.S. money market funds. The Fund may be exposed to additional risks when reinvesting the cash collateral in money market funds that do not seek to maintain a stable NAV per share of $1.00 and which may be subject to redemption gates or liquidity fees under certain circumstances.

Cash received as collateral for securities on loan may be reinvested in certain short-term instruments either directly on behalf of a fund or through one or more joint accounts or money market funds, including those managed by BlackRock Fund Advisors (“BFA”), the Fund’s investment adviser, or its affiliates. As of October 31, 2016, any securities on loan were collateralized by cash and/or U.S. government obligations. Cash collateral received was invested in money market funds managed by BFA and is disclosed in the schedule of investments. The securities on loan for the Fund are also disclosed in its schedule of investments. The total value of any securities on loan as of October 31, 2016 and the total value of the related cash collateral are disclosed in the statement of assets and liabilities. Income earned by the Fund from securities lending is disclosed in the statement of operations.

The risks of securities lending include the risk that the borrower may not provide additional collateral when required or may not return the securities when due. To mitigate these risks, the Fund benefits from a borrower default indemnity provided by BlackRock. BlackRock’s indemnity allows for full replacement of securities lent. The Fund could suffer a loss if the value of the investments purchased with cash collateral falls below the value of the cash collateral received.

For its investment advisory services to the Fund, BFA is entitled to an annual investment advisory fee of 0.75% based on the average daily net assets of the Fund. In addition, the Fund indirectly pays its pro rata share of fees and expenses attributable to its investments in other investment companies (“acquired fund fees and expenses”). BFA has contractually agreed to reduce its investment advisory fee for the Fund through February 28, 2022 so that the investment advisory fee is equal to the acquired fund fees and expenses that would have been experienced by the Fund related to its investments in the iShares J.P. Morgan USD Emerging Markets Bond ETF (“EMB”), after taking into account any fee waivers by EMB, plus 0.10%.

The U.S. Securities and Exchange Commission (the “SEC”) has issued an exemptive order which permits BlackRock Institutional Trust Company, N.A. (“BTC”), an affiliate of BFA, to serve as securities lending agent for the Fund, subject to applicable conditions. 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% (the “collateral investment fees”). Securities lending income is equal to the total of income earned from the reinvestment of cash collateral, net of fees and other payments to and from borrowers of securities, and less the collateral investment fees. The Fund retains a portion of securities lending income and remits the remaining portion to BTC as compensation for its services as securities lending agent.

For the year ended October 31, 2016, the Fund paid to BTC securities lending agent services and collateral investment fees in the amount of $706.

The PNC Financial Services Group, Inc. is the largest stockholder of BlackRock and is considered to be an affiliate of the Fund for 1940 Act purposes.

Purchases and sales of investments (excluding in-kind transactions and short-term investments) for the year ended October 31, 2016, were $58,141 and $138,010, respectively.

There were no in-kind transactions (see Note 4) for the year ended October 31, 2016.

For the year ended October 31, 2016, the average quarter-end notional amount of open interest rate swaps for the Fund (where the Fund pays the fixed rate) was $2,599,000.

A diversified portfolio, where this is appropriate and consistent with a fund’s objectives, minimizes the risk that a price change of a particular investment will have a material impact on the NAV of a fund. The investment concentrations within the Fund’s portfolio are disclosed in its schedule of investments.

The tax character of distributions paid during the years ended October 31, 2016 and October 31, 2015 was as follows:

As of October 31, 2016, the tax components of accumulated net earnings (losses) were as follows:

As of October 31, 2016, the Fund had non-expiring capital loss carryforwards in the amount of $141,292 available to offset future realized capital gains.

In our opinion, the accompanying statement of assets and liabilities, including the schedule of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of iShares Interest Rate Hedged Emerging Markets Bond ETF (the “Fund”) at October 31, 2016, the results of its operations, the changes in its net assets and its financial highlights for each of the periods presented, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at October 31, 2016 by correspondence with the custodian, transfer agent and brokers, provide a reasonable basis for our opinion.

For the fiscal year ended October 31, 2016, the Fund intends to pass through to its shareholders foreign source income of $116,271 earned by the underlying fund.

Under Section 15(c) of the Investment Company Act of 1940 (the “1940 Act”), the Trust’s Board of Trustees (the “Board”), including a majority of Trustees who are not “interested persons” of the Trust (as that term is defined in the 1940 Act) (the “Independent Trustees”), is required annually to consider and approve the Investment Advisory Contract between the Trust and BFA (the “Advisory Contract”) on behalf of the Fund. The Independent Trustees requested, and BFA provided, such information as the Independent Trustees, with advice from independent counsel, deemed reasonably necessary to evaluate the Advisory Contract. A committee of all of the Independent Trustees (the “15(c) Committee”), with independent counsel, met with management on April 28, 2016 and May 9, 2016. At these meetings, the 15(c) Committee reviewed and discussed information provided in response to the 15(c) Committee’s initial requests, and requested certain additional information, which management agreed to provide. At a meeting held on May 17, 2016, management presented information to the Board relating to the continuance of the Advisory Contract, including information requested by the 15(c) Committee during its meetings. The Board, including the Independent Trustees, reviewed and discussed such information at length. The Independent Trustees requested from management certain additional information, which management agreed to provide. At a meeting held on June 21-23, 2016, the Board, including the Independent Trustees, reviewed the additional information provided by management in response to these requests. After extensive discussions, the Board, including all of the Independent Trustees, approved the continuance of the Advisory Contract for the Fund, based on a review of qualitative and quantitative information provided by BFA, including the additional information management provided at the request of the Independent Trustees. The Board noted its satisfaction with the extent and quality of information provided and its frequent interactions with management, as well as the detailed responses and other information provided by BFA. The Board also noted that the Board and BFA agreed to discuss potential enhancements and adjustments to the 15(c) process for the coming year. The Independent Trustees were advised by their independent counsel throughout the process, including about the legal standards applicable to their review. In approving the Advisory Contract for the Fund, the Board, including the Independent Trustees, considered the following factors, no one of which was controlling, and reached the following conclusions:

The Board also noted that the investment advisory fee rate and overall expenses (net of waivers and reimbursements) for the Fund were within range of the median of the investment advisory fee rates and overall expenses (net of waivers and reimbursements) of the funds in its Peer Group, excluding iShares funds.

comparison with its peer group and benchmark index. Such periodic comparative performance information, including additional detailed information on certain specific iShares funds requested by the Board, was also considered. The Board noted that the Fund generally performed in line with expectations relative to the Fund’s peer group and benchmark index over the relevant periods.

Based on this review, the other factors considered at the meeting, and their general knowledge of ETF pricing, the Board concluded that the investment advisory fee rate and expense level and the historical performance of the Fund supported the Board’s approval of the continuance of the Advisory Contract for the coming year.

Nature, Extent and Quality of Services Provided by BFA — Based on management’s representations, including information about recent and proposed enhancements to the iShares business, including with respect to capital markets support and analysis, product design and other services, the Board expected that there would be no diminution in the scope of services required of or provided by BFA under the Advisory Contract for the coming year as compared to the scope of services provided by BFA during prior years. In reviewing the scope of these services, the Board considered BFA’s investment philosophy and experience, noting that BFA and its affiliates have committed significant resources over time, including during the past year, to supporting the iShares funds and their shareholders. The Board also considered BFA’s compliance program and its compliance record with respect to the Fund. In that regard, the Board noted that BFA reports to the Board about portfolio management and compliance matters on a periodic basis in connection with regularly scheduled meetings of the Board, and on other occasions as necessary and appropriate, and has provided information and made appropriate officers available as needed to provide further assistance with these matters. The Board also reviewed the background and experience of the persons responsible for the day-to-day management of the Fund, as well as the resources available to them in managing the Fund. In addition to the above considerations, the Board reviewed and considered detailed presentations regarding BFA’s investment performance, investment and risk management processes and strategies provided at the June 21-23, 2016 meeting and throughout the previous year, and matters related to BFA’s portfolio compliance policies and procedures. The Board noted that the Fund had met its investment objective consistently since its inception date.

Based on review of this information, and the performance information discussed above, the Board concluded that the nature, extent and quality of services provided by BFA to the Fund under the Advisory Contract supported the Board’s approval of the continuance of the Advisory Contract for the coming year.

providing services. The cost information distinguished, among other things, between fixed and variable costs, and explained how the level of fixed and variable costs, as well as the nature of such costs, may impact the existence or size of scale benefits. The Board noted that the Advisory Contract for the Fund did not provide for any breakpoints in the Fund’s investment advisory fee rate as the assets of the Fund increase. However, the Board noted that should material economies of scale exist in the future that are not otherwise shared, a breakpoint structure for the Fund may be appropriate, and that it would continue to monitor the sharing of economies of scale to determine the appropriateness of adding breakpoints in the future.

Fees and Services Provided for Other Comparable Funds/Accounts Managed by BFA and its Affiliates — The Board received and considered information regarding the investment advisory/management fee rates for other funds/accounts in the U.S. for which BFA (or its affiliates) provides investment advisory/management services, including open-end funds registered under the 1940 Act (including sub-advised funds), collective trust funds, and institutional separate accounts (together, the “Other Accounts”), and acknowledged BFA’s assertion that the iShares funds are fundamentally different investment vehicles from the Other Accounts. The Board noted that BFA and its affiliates do not manage Other Accounts with a similar investment strategy or investment mandate as the Fund. The Board further noted that BFA provided the Board with detailed information regarding how the Other Accounts (particularly institutional clients) generally differ from the Fund, including in terms of the different and generally more extensive services provided to the Fund, as well as other significant differences. In that regard, the Board considered that the pricing of services to institutional clients is typically based on a number of factors beyond the nature and extent of the specific services to be provided and often depends on the overall relationship between the client and its affiliates and the adviser and its affiliates. In addition, the Board considered the relative complexity and inherent risks and challenges of managing and providing other services to the Fund, as a publicly traded exchange traded fund, as compared to the Other Accounts that are institutional clients in light of differing regulatory requirements and client-imposed mandates. The Board also considered the “all-inclusive” nature of the Fund’s advisory fee structure, and the Fund expenses borne by BFA under this arrangement. The Board noted that the investment advisory fee rate under the Advisory Contract for the Fund was generally higher than the investment advisory/management fee rates for certain of the Other Accounts (particularly institutional clients) and concluded that the differences appeared to be consistent with the factors discussed.

Other Benefits to BFA and/or its Affiliates — The Board reviewed the “fallout” benefits or ancillary revenue received by BFA and/or its affiliates in connection with the services provided to the Fund by BFA, such as payment of revenue to BTC, the Fund’s securities lending agent, for loaning portfolio securities (which was included in the profit margins reviewed by the Board pursuant to BFA’s profitability methodology), and payment of advisory fees and/or administration fees to BFA and BTC (or their affiliates) in connection with any investments by the Fund in other funds for which BFA (or its affiliates) provides investment advisory services and/or administration services. The Board noted that BFA generally does not use soft dollars or consider the value of research or other services that may be provided to BFA (including its affiliates) in selecting brokers for portfolio transactions for the Fund. The Board further noted that any portfolio transactions on behalf of the Fund placed through a BFA affiliate or purchased from an underwriting syndicate in which a BFA affiliate participates, are reported to the Board pursuant to Rule 17e-1 or Rule 10f-3, as applicable, under the 1940 Act. The Board concluded that any such ancillary benefits would not be disadvantageous to the Fund’s shareholders and thus would not alter the Board’s conclusion with respect to the appropriateness of approving the continuance of the Advisory Contract for the coming year.

The amounts and sources of distributions reported are estimates and are provided pursuant to regulatory requirements and are not being provided for tax reporting purposes. The actual amounts and sources for tax reporting purposes will depend upon the Fund’s investment experience during the year and may be subject to changes based on the tax regulations. Shareholders will receive a Form 1099-DIV each calendar year that will inform them how to report these distributions for federal income tax purposes.

The Board of Trustees 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 (the “BlackRock-advised Funds”) 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. and a Trustee of iShares Trust, and, as a result, oversees a total of 333 funds (as of October 31, 2016) within the Exchange-Traded Fund Complex. Mr. Lawton also serves as an Advisory Board Member for iShares, Inc. and iShares Trust with respect to 333 funds (as of October 31, 2016) within the Exchange-Traded Fund Complex. With the exception of Robert S. Kapito, Mark Wiedman and Benjamin Archibald, the address of each Trustee, Advisory Board Member and officer is c/o BlackRock, Inc., 400 Howard Street, San Francisco, CA 94105. The address of Mr. Kapito, Mr. Wiedman, and Mr. Archibald is c/o BlackRock, Inc., Park Avenue Plaza, 55 East 52^nd Street, New York, NY 10055. The Board has designated Cecilia H. Herbert as its Independent Board Chair.

^a	Investments are denominated in U.S. dollars.

^b	This security may be resold to qualified foreign investors and foreign institutional buyers under Regulation S of the Securities Act of 1933.

^c	This security may be resold to qualified institutional buyers under Rule 144A of the Securities Act of 1933.

^d	Step coupon security. Coupon rate will either increase (step-up bond) or decrease (step-down bond) at regular intervals until maturity. Interest rate shown reflects the rate currently in effect.

^e	Affiliated money market fund.

^f	The rate quoted is the annualized seven-day yield of the fund at period end.

^g	The cost of investments for federal income tax purposes was $9,461,646,001. Net unrealized appreciation was $2,046,524, of which $140,533,275 represented gross unrealized appreciation on securities and $138,486,751 represented gross unrealized depreciation on securities.

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgement exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The fair value hierarchy for the Fund’s investments is included in its schedule of investments.

The accounting records of the Fund are maintained in U.S. dollars. Foreign currencies, as well as investment securities and other assets and liabilities denominated in foreign currencies, are translated into U.S. dollars using exchange rates deemed appropriate by the investment adviser. Purchases and sales of securities, income receipts and expense payments are translated into U.S. dollars on the respective dates of such transactions.

The Fund does not isolate the effect of fluctuations in foreign exchange rates from the effect of fluctuations in the market prices of securities. Such fluctuations are reflected by the Fund as a component of realized and unrealized gains and losses from investments for financial reporting purposes.

The Fund may be subject to foreign taxes (a portion of which may be reclaimable) on income, stock dividends, capital gains on investments, or certain foreign currency transactions. All foreign taxes are recorded in accordance with the applicable foreign tax regulations and rates that exist in the foreign jurisdictions in which the Fund invests. These foreign taxes, if any, are paid by the Fund and are reflected in its statement of operations as follows: foreign taxes withheld at source are presented as a reduction of income, foreign taxes on securities lending income are presented as a reduction of securities lending income, foreign taxes on stock dividends are presented as “other foreign taxes”, and foreign taxes on capital gains from sales of investments and foreign taxes on foreign currency transactions are included in their respective net realized gain (loss) categories. Foreign taxes payable or deferred as of October 31, 2016, if any, are disclosed in the Fund’s statement of assets and liabilities.

For its investment advisory services to the Fund, BFA is entitled to an annual investment advisory fee based on the Fund’s allocable portion of the aggregate of the average daily net assets of the Fund and certain other iShares funds, as follows:

The total of the investment advisory fee and any other fund expenses are a fund’s total annual operating expenses. BFA has contractually agreed to waive a portion of its investment advisory fee for the Fund through February 28, 2018 in order to limit total annual operating expenses after fee waiver to 0.40% of average daily net assets.

For the year ended October 31, 2016, the purchases and sales transactions executed by the Fund, pursuant to Rule 17a-7 under the 1940 Act were $49,154,283 and $57,042,502, respectively.

A diversified portfolio, where this is appropriate and consistent with a fund’s objectives, minimizes the risk that a price change of a particular investment will have a material impact on the NAV of a fund. The investment concentrations within the Fund’s portfolio are disclosed in its schedule of investments.

Investing in the securities of non-U.S. issuers involves certain considerations and risks not typically associated with securities of U.S. issuers. Such risks include, but are not limited to: generally less liquid and less efficient securities markets; generally greater price volatility; exchange rate fluctuations and exchange controls; imposition of restrictions on the expatriation of funds or other assets of the Fund; less publicly available information about issuers; the imposition of withholding or other taxes; higher transaction and custody costs; settlement delays and risk of loss attendant in settlement procedures; difficulties in enforcing contractual obligations; less regulation of securities markets; different accounting, disclosure and reporting requirements; more substantial governmental involvement in the economy; higher inflation rates; greater social, economic and political uncertainties; the risk of nationalization or expropriation of assets; and the risk of war. These risks are heightened for investments in issuers from countries with less developed markets.

The United States and the European Union, along with the regulatory bodies of a number of countries including Japan, Australia and Canada (collectively, “Sanctioning Bodies”), have imposed sectorial economic sanctions on certain Russian individuals and Russian corporate entities which include prohibitions on transacting in or dealing in new debt of longer than 30 or 90 days maturity or new equity of such issuers. Securities held by a fund issued prior to the date of the sanctions being imposed are not currently subject to any restrictions under the sanctions. However, compliance with each of these sanctions may impair the ability of a fund to buy, sell, hold, receive or deliver the affected securities or other securities of such issuers. The Sanctioning Bodies could also institute broader sanctions on Russia. These sanctions, or even the threat of further sanctions, may result in the decline of the value and liquidity of Russian securities, a weakening of the ruble or other adverse consequences to the Russian economy. Current or future sanctions may result in Russia taking counter measures or retaliatory actions, which may further impair the value and liquidity of Russian securities. These retaliatory measures may include the immediate freeze of Russian assets held by a fund.

In our opinion, the accompanying statement of assets and liabilities, including the schedule of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of iShares J.P. Morgan USD Emerging Markets Bond ETF (the “Fund”) at October 31, 2016, the results of its operations, the changes in its net assets and its financial highlights for each of the periods presented, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at October 31, 2016 by correspondence with the custodian, transfer agent and brokers, provide a reasonable basis for our opinion.

Global equity markets advanced modestly for the 12 months ended October 31, 2016 (the “reporting period”). The MSCI ACWI, a broad global equity index that includes both developed and emerging markets, returned 2.05% for the reporting period.

Early in the reporting period, global stock markets declined broadly amid lower energy prices and weaker global economic growth, including slowdowns in stronger developed economies such as the U.S. and U.K. In response, many of the world’s central banks took more aggressive actions to stimulate economic activity, including expanded quantitative easing measures and negative interest rates.

In the U.S., the Federal Reserve Bank (the “Fed”) ended a seven-year period of near-zero interest rates by raising its short-term interest rate target in December 2015. The Fed’s first interest rate hike since June 2006 increased the federal funds target rate from a range of 0%-0.25% to a range of 0.25%-0.50%.

After bottoming in mid-February 2016, global equity markets reversed course, rallying sharply over the ensuing six months. Central bank stimulus activity and a recovery in energy prices helped global equity markets rebound, as did signs of stabilization in China, which had experienced a marked economic slowdown that put downward pressure on its currency. Despite the overall upward trend, geopolitical factors — including the “Brexit” referendum (an affirmative vote for the U.K. to leave the European Union), terrorist attacks in France, and an attempted coup in Turkey — contributed to increased equity market volatility.

Global equity markets gave back some gains over the last two months of the reporting period amid uncertainty about Fed interest rate policy, the outcome of the U.S. presidential election, and growth prospects for the global economy.

Among developed markets, the Asia/Pacific region delivered the best returns, gaining approximately 6% overall for the reporting period. New Zealand and Australia were the leading markets in the region, benefiting from improving economic growth during the reporting period, while the laggards included Singapore and Japan. In particular, the Japanese equity market declined by approximately 10%, but a strong rally in the Japanese yen (which appreciated by 15% against the U.S. dollar) helped offset the overall market decline, resulting in a 3% gain in U.S. dollar terms.

The U.S. equity market returned approximately 4% for the reporting period. Although employment growth remained robust, other segments of the U.S. economy struggled, leading to three consecutive quarters of growth below a 1.5% annual rate. As a result, the Fed — which was expected to raise short-term interest rates further in 2016 — held rates steady through the first 10 months of the year. However, improving economic activity late in the reporting period led to expectations of another Fed rate hike before the end of the year.

European stock markets declined by approximately 7% for the reporting period. Markets in Italy and Spain, which were adversely affected by political instability and struggling banking sectors, declined the most, while Austria and Portugal performed the best. In the U.K., the equity market advanced by about 13%, but a sharp decline in the British pound in the wake of the Brexit vote in June led to negative returns in U.S. dollar terms.

Emerging markets stocks outperformed developed markets, advancing by more than 9% for the reporting period in U.S. dollar terms. Latin American equity markets generated the best returns, led by rebounding markets in Peru and Brazil, while emerging markets in Europe and the Middle East lagged.

The inception date of the Fund was 10/15/14. The first day of secondary market trading was 10/16/14.

The S&P GSCI^TM Commodity Total Return Index is an unmanaged index that measures the performance of general commodity price movements and inflation in the world economy.

The iShares Commodities Select Strategy ETF (the “Fund”) seeks total return by providing investors with broad commodity exposure. The Fund is an actively managed exchange-traded fund that does not seek to replicate the performance of a specified index. For the 12-month reporting period ended October 31, 2016, the total return for the Fund was -1.23%, net of fees.

The Fund declined slightly overall in a volatile period for commodities and commodity-related investments. The Fund maintained its broad commodities exposure by investing approximately 70% in commodity-linked futures contracts and 30% in commodity-related stocks during the reporting period. While the equity component rose for the reporting period, largely due to positive results from metals and mining stocks, the futures portion of the Fund declined, resulting in a negative overall return.

Commodity prices generally fell in late 2015, reflecting a marked slowdown in global economic activity. After bottoming in early 2016, however, commodity prices staged a broad recovery over the remainder of the reporting period in response to increased economic stimulus efforts and improving global economic growth.

Futures in the energy sector, which represented more than 60% of the total futures exposure at the end of the reporting period, detracted the most from the Fund’s performance. Although energy prices stabilized during the reporting period, they declined overall as a result of continued excess supply and weak demand. Agricultural and livestock futures, which represented more than a quarter of the Fund at the end of the reporting period, benefited from changing consumption patterns, rising demand in China and other emerging markets, and increased investment demand.

In the equity component, commodity-related stocks from the United Kingdom, Australia, the United States, and Canada contributed the most to Fund performance. By industry segment, diversified metals and mining companies were the leading contributors, followed by paper and packaging companies and gold miners. On the downside, energy stocks were the largest detractors from the Fund’s performance for the reporting period.

These consolidated financial statements relate only to the following fund (the “Fund”):

The Fund carries out its investment strategies associated with investment in commodity-linked futures contracts and other derivatives (“commodity-linked investments”) by investing up to 25% of its total assets in iShares Commodities Strategy Cayman Ltd., a wholly-owned subsidiary organized in the Cayman Islands (the “Subsidiary”). The investment adviser of the Fund also serves as the investment adviser to the Subsidiary. Investments in the Subsidiary enable the Fund to hold the commodity-linked investments and satisfy regulated investment company tax requirements. The accompanying consolidated schedule of investments and consolidated financial statements for the Fund include the positions and accounts, respectively, of its Subsidiary. Intercompany accounts and transactions, if any, have been eliminated.

The following table shows a summary of selected financial information of the Subsidiary included in the consolidated financial statements of the Fund, as of and for the year ended October 31, 2016:

the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgement exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The fair value hierarchy for the Fund’s investments is included in its consolidated schedule of investments.

Security transactions are accounted for on trade date. Dividend income and capital gain distributions, if any, are recognized on the ex-dividend date, net of any foreign taxes withheld at source. Any taxes withheld that are reclaimable from foreign tax authorities as of October 31, 2016 are reflected in tax reclaims receivable. Non-cash dividends received in the form of stock in an elective dividend, if any, are recorded as dividend income at fair value. Distributions received by the Fund may include a return of capital that is estimated by management. Such amounts are recorded as a reduction of the cost of investments or reclassified to capital gains. Interest income, including amortization and accretion of premiums and discounts on debt securities, is recognized daily on the accrual basis. Realized gains and losses on investment transactions are determined using the specific identification method.

The Fund may be subject to foreign taxes (a portion of which may be reclaimable) on income, stock dividends, capital gains on investments, or certain foreign currency transactions. All foreign taxes are recorded in accordance with the applicable foreign tax regulations and rates that exist in the foreign jurisdictions in which the Fund invests. These foreign taxes, if any, are paid by the Fund and are reflected in its consolidated statement of operations as follows: foreign taxes withheld at source are presented as a reduction of income, foreign taxes on securities lending income are presented as a reduction of securities lending income, foreign taxes on stock dividends are presented as “other foreign taxes”, and foreign taxes on capital gains from sales of investments and foreign taxes on foreign currency transactions are included in their respective net realized gain (loss) categories. Foreign taxes payable or deferred as of October 31, 2016, if any, are disclosed in the Fund’s consolidated statement of assets and liabilities.

The Fund may lend its investment securities to approved borrowers, such as brokers, dealers and other financial institutions. The borrower pledges and maintains with the Fund collateral consisting of cash, an irrevocable letter of credit issued by a bank, or securities issued or guaranteed by the U.S. government. The initial collateral received by the Fund is required to have a value of at least 102% of the current value of the loaned securities for securities traded on U.S. exchanges and a value of at least 105% for all other securities. The collateral is maintained thereafter at a value equal to at least 100% of the current value of the securities on loan. The market value of the loaned securities is determined at the close of each business day of the Fund. Any additional required collateral is delivered to the Fund and any excess collateral is returned by the Fund on the next business day. During the term of the loan, the Fund is entitled to all distributions made on or in respect of the loaned securities but does not receive interest income on securities received as collateral. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within the standard time period for settlement of securities transactions.

On October 11, 2016, BlackRock, Inc. (“BlackRock”) implemented changes required by amendments to Rule 2a-7 under the 1940 Act, which governs the operations of U.S. money market funds. The Fund may be exposed to additional risks when reinvesting the cash collateral in money market funds that do not seek to maintain a stable NAV per share of $1.00 and which may be subject to redemption gates or liquidity fees under certain circumstances.

Cash received as collateral for securities on loan may be reinvested in certain short-term instruments either directly on behalf of a fund or through one or more joint accounts or money market funds, including those managed by BlackRock Fund Advisors (“BFA”), the Fund’s investment adviser, or its affiliates. As of October 31, 2016, any securities on loan were collateralized by cash and/or U.S. government obligations. Cash collateral received was invested in money market funds managed by BFA and is disclosed in the consolidated schedule of investments. The securities on loan for the Fund are also disclosed in its consolidated schedule of investments. The total value of any securities on loan as of October 31, 2016 and the total value of the related cash collateral are disclosed in the consolidated statement of assets and liabilities. Income earned by the Fund from securities lending is disclosed in the consolidated statement of operations.

The risks of securities lending include the risk that the borrower may not provide additional collateral when required or may not return the securities when due. To mitigate these risks, the Fund benefits from a borrower default indemnity provided by BlackRock. BlackRock’s indemnity allows for full replacement of securities lent. The Fund could suffer a loss if the value of the investments purchased with cash collateral falls below the value of the cash collateral received.

The following table is a summary of securities lending agreements which are subject to offset under an MSLA as of October 31, 2016:

The Subsidiary has entered into a separate contract with BFA under which BFA provides investment advisory services to the Subsidiary but does not receive separate compensation from the Subsidiary for providing it with such services. The Subsidiary has also entered into separate arrangements that provide for the provision of other services to the Subsidiary (including administrative, custody, transfer agency and other services), and BFA pays the costs and expenses related to the provision of those services.

BFA has entered into a sub-advisory agreement with BlackRock International Limited (the “Sub-Adviser”), an affiliate of BFA, under which BFA pays the Sub-Adviser for services it provides to the Fund and the Subsidiary.

For its investment advisory services to the Fund, BFA is entitled to an annual investment advisory fee of 0.48% based on the average daily net assets of the Fund. In addition, the Fund indirectly pays its pro rata share of fees and expenses attributable to its investments in other investment companies (“acquired fund fees and expenses”). BFA has contractually agreed to waive a portion of its investment advisory fees for the Fund through February 28, 2019 in an amount equal to the acquired fund fees and expenses attributable to the Fund’s investments in other registered investment companies advised by BFA or its affiliates, if any.

The U.S. Securities and Exchange Commission (the “SEC”) has issued an exemptive order which permits BlackRock Institutional Trust Company, N.A. (“BTC”), an affiliate of BFA, to serve as securities lending agent for the Fund, subject to applicable conditions. 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% (the “collateral investment fees”). Securities lending income is equal to the total of income earned from the reinvestment of cash collateral, net of fees and other payments to and from borrowers of securities, and less the collateral investment fees. The Fund retains a portion of securities lending income and remits the remaining portion to BTC as compensation for its services as securities lending agent.

For the year ended October 31, 2016, the Fund paid to BTC securities lending agent services and collateral investment fees in the amount of $18,576.

The PNC Financial Services Group, Inc. is the largest stockholder of BlackRock and is considered to be an affiliate of the Fund for 1940 Act purposes.

Purchases and sales of investments (excluding in-kind transactions and short-term investments) for the year ended October 31, 2016, were $35,868,302 and $42,729,759, respectively.

In-kind purchases and sales (see Note 4) for the year ended October 31, 2016, were $33,782,920 and $14,401,362, respectively.

The Fund may purchase or sell futures contracts as part of its investment strategy. A futures contract is a standardized, exchange-traded agreement to buy or sell a financial instrument at a set price on a future date. Upon entering into a futures contract, the Fund is required to pledge to the executing broker which holds segregated from its own assets, an amount of cash, U.S. government securities or other high-quality debt and equity securities equal to the minimum initial margin requirements of the exchange on which the contract is traded. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as margin variation and are recorded by the Fund as unrealized appreciation or depreciation. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Losses may arise if the value of a futures contract decreases due to an unfavorable change in the market rates or values of the underlying instrument during the term of the contract or if the counterparty does not perform under the contract. The use of futures contracts also involves the risk of an imperfect correlation in the movements in the price of futures contracts and the assets underlying such contracts.

The following table shows the value of futures contracts held as of October 31, 2016 and the related locations in the consolidated statement of assets and liabilities, presented by risk exposure category:

The following table shows the realized and unrealized gains (losses) on futures contracts held during the year ended October 31, 2016 and the related locations in the consolidated statement of operations, presented by risk exposure category:

The following table shows the average quarter-end balances of open futures contracts for the year ended October 31, 2016:

A diversified portfolio, where this is appropriate and consistent with a fund’s objectives, minimizes the risk that a price change of a particular investment will have a material impact on the NAV of a fund. The investment concentrations within the Fund’s portfolio are disclosed in its consolidated schedule of investments.

The Fund concentrates its investments in securities and derivatives linked to commodities or commodities markets. Commodity prices may be influenced or characterized by unpredictable factors, including, where applicable, high volatility, changes in supply and demand relationships, weather, agriculture, trade, pestilence, political instability, changes in interest rates and monetary and other governmental policies. Securities of companies held by the Fund that are dependent on a single commodity, or are concentrated in a single commodity sector, may typically exhibit volatility attributable to commodity prices.

the financial stability of those counterparties. Financial assets, which potentially expose a fund to issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of a fund’s exposure to credit and counterparty risks with respect to those financial assets is approximated by their value recorded in its statement of assets and liabilities.

Net income and realized gains from investments held by the Subsidiary are treated as ordinary income for tax purposes and any net income or net gains will pass through to the Fund as such. Accordingly, the net investment income (loss) and realized gains (losses) reported in the Fund’s financial statements for such investments held by the Subsidiary may differ significantly from distributions. In addition, if a net loss is realized by the Subsidiary in any taxable year, the loss will not be available to offset the Fund’s ordinary income and/or capital gains for that year.

U.S. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or NAV per share. The following permanent differences as of October 31, 2016, attributable to the characterization of corporate actions, passive foreign investment companies, foreign currency transactions, the character of income (losses) from a wholly-owned foreign subsidiary and realized gains (losses) from in-kind redemptions, were reclassified to the following accounts:

The tax character of distributions paid during the years ended October 31, 2016 and October 31, 2015 were as follows:

As of October 31, 2016, the tax components of accumulated net earnings (losses) were as follows:

As of October 31, 2016, the Fund had non-expiring capital loss carryforwards in the amount of $16,864,975 available to offset future realized capital gains.

The Fund may own shares in certain foreign investment entities, referred to, under U.S. tax law, as “passive foreign investment companies.” The Fund may elect to mark-to-market annually the shares of each passive foreign investment company and would be required to distribute to shareholders any such marked-to-market gains.

Management has evaluated the impact of all subsequent events on the Fund through the date the consolidated financial statements were available to be issued and has determined that there were no subsequent events requiring adjustment or disclosure in the consolidated financial statements.

In our opinion, the accompanying consolidated statement of assets and liabilities, including the consolidated schedule of investments, and the related consolidated statements of operations and of changes in net assets and the consolidated financial highlights present fairly, in all material respects, the financial position of iShares Commodities Select Strategy ETF and its subsidiary (collectively, the “Fund”) at October 31, 2016, the results of their operations, the changes in their net assets and their financial highlights for each of the periods presented, in conformity with accounting principles generally accepted in the United States of America. These consolidated financial statements and consolidated financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at October 31, 2016 by correspondence with the custodian, transfer agent and brokers, provide a reasonable basis for our opinion.

The Fund hereby designates the maximum amount of $1,347,562 as qualified dividend income for individuals for the fiscal year ended October 31, 2016.

For corporate shareholders, the percentage of income dividends paid by the by the Fund during the fiscal year ended October 31, 2016 that qualified for the dividends-received deduction was 51.27%.

The Fund hereby designates $205,007 as the amount of distributions from direct federal obligation interest for the fiscal year ended October 31, 2016. The law varies in each state as to whether and what percentage of ordinary income dividends attributable to federal obligations is exempt from state income tax. Shareholders are advised to check with their tax advisers to determine if any portion of the dividends received is exempt from state income tax.

Under Section 15(c) of the Investment Company Act of 1940 (the “1940 Act”), the Trust’s Board of Trustees (the “Board”), including a majority of Trustees who are not “interested persons” of the Trust (as that term is defined in the 1940 Act) (the “Independent Trustees”), is required annually to consider and approve the Investment Advisory Contract between the Trust and BFA (the “Advisory Contract”), and the Sub-Advisory Agreement between BFA and BlackRock International Limited (“BIL”) (the “Sub-Advisory Agreement”), on behalf of the Fund. The Advisory Contract and the Sub-Advisory Agreement are referred to hereafter as the “Advisory Agreements”. The Independent Trustees requested, and BFA provided, such information as the Independent Trustees, with advice from independent counsel, deemed reasonably necessary to evaluate the Advisory Agreements. A committee of all of the Independent Trustees (the “15(c) Committee”), with independent counsel, met with management on April 28, 2016 and May 9, 2016. At these meetings, the 15(c) Committee reviewed and discussed information provided in response to the 15(c) Committee’s initial requests, and requested certain additional information, which management agreed to provide. At a meeting held on May 17, 2016, management presented information to the Board relating to the continuance of the Advisory Agreements, including information requested by the 15(c) Committee during its meetings. The Board, including the Independent Trustees, reviewed and discussed such information at length. The Independent Trustees requested from management certain additional information, which management agreed to provide. At a meeting held on June 21-23, 2016, the Board, including the Independent Trustees, reviewed the additional information provided by management in response to these requests. After extensive discussions, the Board, including all of the Independent Trustees, approved the continuance of the Advisory Agreements for the Fund, based on a review of qualitative and quantitative information provided by BFA, including the additional information management provided at the request of the Independent Trustees. The Board noted its satisfaction with the extent and quality of information provided and its frequent interactions with management, as well as the detailed responses and other information provided by BFA. The Board also noted that the Board and BFA agreed to discuss potential enhancements and adjustments to the 15(c) process for the coming year. The Independent Trustees were advised by their independent counsel throughout the process, including about the legal standards applicable to their review. In approving the Advisory Agreements for the Fund, the Board, including the Independent Trustees, considered the following factors, no one of which was controlling, and reached the following conclusions:

The Board also noted that the investment advisory fee rate and overall expenses (net of waivers and reimbursements) for the Fund were lower than the median of the investment advisory fee rates and overall expenses (net of waivers and reimbursements) of the funds in its Peer Group, excluding iShares funds. The Board also noted that BFA pays BIL for its sub-advisory services, and that there are no additional fees imposed on the Fund in respect of the services provided under the Sub-Advisory Agreement.

Based on this review, the other factors considered at the meeting, and their general knowledge of ETF pricing, the Board concluded that the investment advisory fee rate and expense level and the historical performance of the Fund supported the Board’s approval of the continuance of the Advisory Agreements for the coming year.

Nature, Extent and Quality of Services Provided by BFA and BIL or their Affiliates — Based on management’s representations, including information about recent and proposed enhancements to the iShares business, including with respect to capital markets support and analysis, product design and other services, the Board expected that there would be no diminution in the scope of services required of or provided by BFA (and any services provided by BIL on BFA’s behalf or at BFA’s direction) under the Advisory Agreements for the coming year as compared to the scope of services provided by BFA and BIL during prior years. In reviewing the scope of these services, the Board considered the investment philosophy and experience of BFA and BIL, noting that BFA and its affiliates have committed significant resources over time, including during the past year, to supporting the iShares funds and their shareholders. The Board also considered the compliance program of BFA and BIL and their compliance record with respect to the Fund. In that regard, the Board noted that BFA reports to the Board about portfolio management and compliance matters on a periodic basis in connection with regularly scheduled meetings of the Board, and on other occasions as necessary and appropriate, and has provided information and made appropriate officers available as needed to provide further assistance with these matters. The Board also reviewed the background and experience of the persons responsible for the day-to-day management of the Fund, as well as the resources available to them in managing the Fund. In addition to the above considerations, the Board reviewed and considered detailed presentations regarding BFA’s investment performance, investment and risk management processes and strategies provided at the June 21-23, 2016 meeting and throughout the previous year, and matters related to BFA’s and BIL’s portfolio compliance policies and procedures, and BFA’s oversight of the services provided by BIL. The Board noted that the Fund had met its investment objective consistently since its inception date.

Based on review of this information, and the performance information discussed above, the Board concluded that the nature, extent and quality of services provided by BFA and BIL to the Fund under the Advisory Agreements supported the Board’s approval of the continuance of the Advisory Agreements for the coming year.

Costs of Services Provided to the Fund and Profits Realized by BFA and its Affiliates — The Board reviewed information about the profitability to BlackRock of the Fund, based on the fees payable to BFA and its affiliates (including fees under the Advisory Contract), and all other sources of revenue and expense to BFA and its affiliates from the Fund’s operations for the last calendar year. The Board reviewed BlackRock’s profitability methodology for the iShares funds, noting that the 15(c) Committee had focused on the methodology and profitability presentation during its meetings. The Board discussed the sources of direct and ancillary revenue with management, including the revenues to BTC from securities lending by the Fund. The Board also discussed BFA’s profit margin as reflected in the Fund’s profitability analysis and reviewed information regarding potential economies of scale (as discussed below). Based on this review, the Board concluded that the profits realized by BFA and its affiliates under the Advisory Agreements and from other relationships between the Fund and BFA and/or its affiliates, if any, were within a reasonable range in light of the factors considered.

Fees and Services Provided for Other Comparable Funds/Accounts Managed by BFA and its Affiliates — The Board received and considered information regarding the investment advisory/management fee rates for other funds/accounts in the U.S. for which BFA (or its affiliates) provides investment advisory/management services, including open-end funds registered under the 1940 Act (including sub-advised funds), collective trust funds, and institutional separate accounts (together, the “Other Accounts”), and acknowledged BFA’s assertion that the iShares funds are fundamentally different investment vehicles from the Other Accounts. The Board noted that BFA and its affiliates do not manage Other Accounts with a similar investment strategy or investment mandate as the Fund. The Board further noted that BFA provided the Board with detailed information regarding how the Other Accounts (particularly institutional clients) generally differ from the Fund, including in terms of the different and generally more extensive services provided to the Fund, as well as other significant differences. In that regard, the Board considered that the pricing of services to institutional clients is typically based on a number of factors beyond the nature and extent of the specific services to be provided and often depends on the overall relationship between the client and its affiliates and the adviser and its affiliates. In addition, the Board considered the relative complexity and inherent risks and challenges of managing and providing other services to the Fund, as a publicly traded exchange traded fund, as compared to the Other Accounts that are institutional clients in light of differing regulatory requirements and client-imposed mandates. The Board also considered the “all-inclusive” nature of the Fund’s advisory fee structure, and the Fund expenses borne by BFA under this arrangement. The Board noted that the investment advisory fee rate under the Advisory Contract for the Fund was generally higher than the investment advisory/management fee rates for certain of the Other Accounts (particularly institutional clients) and concluded that the differences appeared to be consistent with the factors discussed.

Other Benefits to BFA and/or its Affiliates — The Board reviewed the “fallout” benefits or ancillary revenue received by BFA and/or its affiliates in connection with the services provided to the Fund by BFA, such as payment of revenue to BTC, the Fund’s securities lending agent, for loaning portfolio securities (which was included in the profit margins reviewed by the Board pursuant to BFA’s profitability methodology), and payment of advisory fees and/or administration fees to BFA and BTC (or their affiliates) in connection with any investments by the Fund in other funds for which BFA (or its affiliates) provides investment advisory services and/or administration services. The Board noted that BFA and BIL generally do not use soft dollars or consider the value of research or other services that may be provided to BFA and BIL (including their affiliates) in selecting brokers for portfolio transactions for the Fund. The Board further noted that any portfolio transactions on behalf of the Fund placed through a BFA affiliate or purchased from an underwriting syndicate in which a BFA affiliate participates, are reported to the Board pursuant to Rule 17e-1 or Rule 10f-3, as applicable, under the 1940 Act. The Board concluded that any such ancillary benefits would not be

disadvantageous to the Fund’s shareholders and thus would not alter the Board’s conclusion with respect to the appropriateness of approving the continuance of the Advisory Agreements for the coming year.

The amounts and sources of distributions reported are estimates and are provided pursuant to regulatory requirements and are not being provided for tax reporting purposes. The actual amounts and sources for tax reporting purposes will depend upon the Fund’s investment experience during the year and may be subject to changes based on the tax regulations. Shareholders will receive a Form 1099-DIV each calendar year that will inform them how to report these distributions for federal income tax purposes.

This report is intended for the Fund’s shareholders. It may not be distributed to prospective investors unless it is preceded or accompanied by the current prospectus.

The iShares Funds are distributed by BlackRock Investments, LLC (together with its affiliates, “BlackRock”).

The inception date of the Fund was 2/24/15. The first day of secondary market trading was 2/26/15.

The Bloomberg Barclays U.S. Aggregate Bond Index (formerly the Barclays U.S. Aggregate Bond Index) is a widely recognized unmanaged market-weighted index, comprised of investment-grade corporate bonds rated BBB or better, mortgages and U.S. Treasury and U.S. Government agency issues with at least one year to maturity.

The iShares Edge U.S. Fixed Income Balanced Risk ETF (the “Fund”) (formerly the iShares U.S. Fixed Income Balanced Risk ETF) seeks total return and preservation of capital by investing, under normal circumstances, at least 80% of its net assets in U.S. dollar denominated investment-grade and high-yield fixed-income securities that in the aggregate has approximately equal exposure to credit spread risk and interest rate risk. The Fund is an actively managed exchange-traded fund that does not seek to replicate the performance of a specified index. For the 12-month reporting period ended October 31, 2016, the total return for the Fund was 5.32%, net of fees.

The Fund posted a positive return for the reporting period and outpaced the broad U.S. fixed-income market due to a larger allocation to investment-grade and high-yield corporate securities relative to the Bloomberg Barclays U.S. Aggregate Bond Index. The interest rate hedge component detracted from performance as interest rates declined overall during the reporting period. Similarly, the Fund had a shorter duration (less price sensitivity to interest rate changes) relative to the broader U.S. bond market, which detracted from performance compared with the Bloomberg Barclays U.S. Aggregate Bond Index.

Within the corporate bond allocation, the Fund benefited significantly from an overweight position in financial and industrial securities relative to the Bloomberg Barclays U.S. Aggregate Bond Index. These bonds performed well due to sustained investor demand for higher-yielding securities in an environment of record low interest rates available on U.S. Treasury securities.

An overweight position in government agency mortgage-backed securities (“MBS”) detracted slightly from Fund performance as this segment of the bond market underperformed the Bloomberg Barclays U.S. Aggregate Bond Index. In addition, the Fund’s lower interest rate sensitivity detracted from relative performance.

During the reporting period, risk decreased for MBS and increased for both high-yield and intermediate-term investment-grade corporate securities. Because the managers allocate equal risk among each credit sector, the Fund’s allocation to high-yield and intermediate-term investment-grade corporate bonds declined, while the allocation to MBS increased for the reporting period.

Actual Expenses — The table provides information about actual account values and actual expenses. Annualized expense ratios reflect contractual and voluntary fee waivers, if any. To estimate the expenses that you paid on your account over the period, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number under the heading entitled “Expenses Paid During Period.”

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgement exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The fair value hierarchy for the Fund’s investments is included in its schedule of investments.

The Fund may purchase mortgage pass-through securities on a when-issued or to-be-announced (“TBA”) basis, with payment and delivery scheduled for a future date. The Fund may enter into a TBA agreement, sell the obligation to purchase the pools stipulated in the TBA agreement prior to the stipulated settlement date and enter into a new TBA agreement for future delivery of pools of mortgage pass-through securities (a “TBA roll”). A TBA roll is treated by the Fund as a purchase transaction and a sale transaction in which the Fund realizes a gain or loss. The Fund’s use of TBA rolls may cause the Fund to experience higher portfolio turnover and higher transaction costs. The Fund could be exposed to possible risk if there are adverse market actions, expenses or delays in connection with the TBA transactions, or if the counterparty fails to complete the transaction.

To mitigate counterparty risk, the Fund has entered into a two-way collateral agreement for TBA transactions with certain counterparties. Under such agreement, the “in-the-money” party of a TBA transaction may at any time require the other party to pledge collateral assets (in the form of cash or securities) to offset any loss the in-the-money party would incur upon cancellation of the TBA transaction. A party is in-the-money if they are the buyer and the market value of the TBA transaction increases or if they are the seller and the market value of the TBA transaction decreases. Cash received as collateral from the counterparty may be reinvested in money market funds, including those managed by the Fund’s investment adviser, or its affiliates. Such collateral, if any, is presented in the statement of assets and liabilities as “Investments in securities – affiliated” and “Payable due to broker for TBA collateral.” Securities pledged as collateral by the Fund, if any, are noted in the schedule of investments.

The Fund may lend its investment securities to approved borrowers, such as brokers, dealers and other financial institutions. The borrower pledges and maintains with the Fund collateral consisting of cash, an irrevocable letter of credit issued by a bank, or securities issued or guaranteed by the U.S. government. The initial collateral received by the Fund is required to have a value of at least 102% of the current value of the loaned securities plus the interest accrued on such securities, if any, for securities traded on U.S. exchanges and a value of at least 105% for all other securities. The collateral is maintained thereafter at a value equal to at least 100% of the current value of the securities on loan plus accrued interest, if any. The market value of the loaned securities is determined at the close of each business day of the Fund. Any additional required collateral is delivered to the Fund and any excess collateral is returned by the Fund on the next business day. During the term of the loan, the Fund is entitled to all distributions made on or in respect of the loaned securities but does not receive interest income on securities received as collateral. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within the standard time period for settlement of securities transactions.

On October 11, 2016, BlackRock, Inc. (“BlackRock”) implemented changes required by amendments to Rule 2a-7 under the 1940 Act, which governs the operations of U.S. money market funds. The Fund may be exposed to additional risks when reinvesting the cash collateral in money market funds that do not seek to maintain a stable NAV per share of $1.00 and which may be subject to redemption gates or liquidity fees under certain circumstances.

disclosed in the schedule of investments. The securities on loan for the Fund are also disclosed in its schedule of investments. The total value of any securities on loan as of October 31, 2016 and the total value of the related cash collateral are disclosed in the statement of assets and liabilities. Income earned by the Fund from securities lending is disclosed in the statement of operations.

The risks of securities lending include the risk that the borrower may not provide additional collateral when required or may not return the securities when due. To mitigate these risks, the Fund benefits from a borrower default indemnity provided by BlackRock. BlackRock’s indemnity allows for full replacement of securities lent. The Fund could suffer a loss if the value of the investments purchased with cash collateral falls below the value of the cash collateral received.

The following table is a summary of securities lending agreements which are subject to offset under an MSLA as of October 31, 2016:

For its investment advisory services to the Fund, BFA is entitled to an annual investment advisory fee of 0.25% based on the average daily net assets of the Fund. In addition, the Fund indirectly pays its pro rata share of fees and expenses attributable to its investments in other investment companies (“acquired fund fees and expenses”). BFA has contractually agreed to waive a portion of its investment advisory fees for the Fund through February 28, 2019 in an amount equal to the acquired fund fees and expenses attributable to the Fund’s investments in other registered investment companies advised by BFA or its affiliates, if any.

The U.S. Securities and Exchange Commission (the “SEC”) has issued an exemptive order which permits BlackRock Institutional Trust Company, N.A. (“BTC”), an affiliate of BFA, to serve as securities lending agent for the Fund, subject to applicable conditions. 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% (the “collateral investment fees”). Securities lending income is equal to the total of income earned from the reinvestment of cash collateral, net of fees and other payments to and from borrowers of securities, and less the collateral investment fees. The Fund retains a portion of securities lending income and remits the remaining portion to BTC as compensation for its services as securities lending agent.

For the year ended October 31, 2016, the Fund paid to BTC securities lending agent services and collateral investment fees in the amount of $6,782.

The PNC Financial Services Group, Inc. is the largest stockholder of BlackRock and is considered to be an affiliate of the Fund for 1940 Act purposes.

Purchases and sales of investments (excluding in-kind transactions and short-term investments) for the year ended October 31, 2016 were as follows:

A diversified portfolio, where this is appropriate and consistent with a fund’s objectives, minimizes the risk that a price change of a particular investment will have a material impact on the NAV of a fund. The investment concentrations within the Fund’s portfolio are disclosed in its schedule of investments.

Changes in market interest rates or economic conditions may affect the value and/or liquidity of fixed income investments. Interest rate risk is the risk that prices of bonds and other fixed-income securities will decrease as interest rates rise and increase as interest rates fall. Mortgage-backed securities and securities with longer durations, tend to be more sensitive to interest rate changes, usually making them more volatile than other types of bonds or securities with shorter durations. Given the environment of historically low interest rates, a fund may be subject to a greater risk of price losses if interest rates rise.

The tax character of distributions paid during the years ended October 31, 2016 and October 31, 2015 was as follows:

As of October 31, 2016, the tax components of accumulated net earnings (losses) were as follows:

As of October 31, 2016, the Fund had non-expiring capital loss carryforwards in the amount of $260,711 available to offset future realized capital gain.

In our opinion, the accompanying statement of assets and liabilities, including the schedule of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of iShares Edge U.S. Fixed Income Balanced Risk ETF (the “Fund”) at October 31, 2016, the results of its operations, the changes in its net assets and its financial highlights for each of the periods presented, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at October 31, 2016 by correspondence with the custodian, transfer agent and brokers, provide a reasonable basis for our opinion.

For the fiscal year ended October 31, 2016, the Fund hereby designates $1,506,314 as the maximum amount allowable as interest-related dividends eligible for exemption from U.S. withholding tax for nonresident aliens and foreign corporations.

The Fund hereby designates $112 as the amount of distributions from direct federal obligation interest for the fiscal year ended October 31, 2016. The law varies in each state as to whether and what percentage of ordinary income dividends attributable to federal obligations is exempt from state income tax. Shareholders are advised to check with their tax advisers to determine if any portion of the dividends received is exempt from state income tax.

Under Section 15(c) of the Investment Company Act of 1940 (the “1940 Act”), the Trust’s Board of Trustees (the “Board”), including a majority of Trustees who are not “interested persons” of the Trust (as that term is defined in the 1940 Act) (the “Independent Trustees”), is required annually to consider and approve the Investment Advisory Contract between the Trust and BFA (the “Advisory Contract”) on behalf of the Fund. The Independent Trustees requested, and BFA provided, such information as the Independent Trustees, with advice from independent counsel, deemed reasonably necessary to evaluate the Advisory Contract. A committee of all of the Independent Trustees (the “15(c) Committee”), with independent counsel, met with management on April 28, 2016 and May 9, 2016. At these meetings, the 15(c) Committee reviewed and discussed information provided in response to the 15(c) Committee’s initial requests, and requested certain additional information, which management agreed to provide. At a meeting held on May 17, 2016, management presented information to the Board relating to the continuance of the Advisory Contract, including information requested by the 15(c) Committee during its meetings. The Board, including the Independent Trustees, reviewed and discussed such information at length. The Independent Trustees requested from management certain additional information, which management agreed to provide. At a meeting held on June 21-23, 2016, the Board, including the Independent Trustees, reviewed the additional information provided by management in response to these requests. After extensive discussions, the Board, including all of the Independent Trustees, approved the continuance of the Advisory Contract for the Fund, based on a review of qualitative and quantitative information provided by BFA, including the additional information management provided at the request of the Independent Trustees. The Board noted its satisfaction with the extent and quality of information provided and its frequent interactions with management, as well as the detailed responses and other information provided by BFA. The Board also noted that the Board and BFA agreed to discuss potential enhancements and adjustments to the 15(c) process for the coming year. The Independent Trustees were advised by their independent counsel throughout the process, including about the legal standards applicable to their review. In approving the Advisory Contract for the Fund, the Board, including the Independent Trustees, considered the following factors, no one of which was controlling, and reached the following conclusions:

Based on this review, the other factors considered at the meeting, and their general knowledge of ETF pricing, the Board concluded that the investment advisory fee rate and expense level and the historical performance of the Fund supported the Board’s approval of the continuance of the Advisory Contract for the coming year.

Nature, Extent and Quality of Services Provided by BFA — Based on management’s representations, including information about recent and proposed enhancements to the iShares business, including with respect to capital markets support and analysis, product design and other services, the Board expected that there would be no diminution in the scope of services required of or provided by BFA under the Advisory Contract for the coming year as compared to the scope of services provided by BFA during prior years. In reviewing the scope of these services, the Board considered BFA’s investment philosophy and experience, noting that BFA and its affiliates have committed significant resources over time, including during the past year, to supporting the iShares funds and their shareholders. The Board also considered BFA’s compliance program and its compliance record with respect to the Fund. In that regard, the Board noted that BFA reports to the Board about portfolio management and compliance matters on a periodic basis in connection with regularly scheduled meetings of the Board, and on other occasions as necessary and appropriate, and has provided information and made appropriate officers available as needed to provide further assistance with these matters. The Board also reviewed the background and experience of the persons responsible for the day-to-day management of the Fund, as well as the resources available to them in managing the Fund. In addition to the above considerations, the Board reviewed and considered detailed presentations regarding BFA’s investment performance, investment and risk management processes and strategies provided at the June 21-23, 2016 meeting and throughout the previous year, and matters related to BFA’s portfolio compliance policies and procedures. The Board noted that the Fund had met its investment objective consistently since its inception date.

Based on review of this information, and the performance information discussed above, the Board concluded that the nature, extent and quality of services provided by BFA to the Fund under the Advisory Contract supported the Board’s approval of the continuance of the Advisory Contract for the coming year.

Fees and Services Provided for Other Comparable Funds/Accounts Managed by BFA and its Affiliates — The Board received and considered information regarding the investment advisory/management fee rates for other funds/accounts in the U.S. for which BFA (or its affiliates) provides investment advisory/management services, including open-end funds registered under the 1940 Act (including sub-advised funds), collective trust funds, and institutional separate accounts (together, the “Other Accounts”), and acknowledged BFA’s assertion that the iShares funds are fundamentally different investment vehicles from the Other Accounts. The Board noted that BFA and its affiliates do manage Other Accounts with a similar investment strategy or investment mandate as the Fund. The Board further noted that BFA provided the Board with detailed information regarding how the Other Accounts (particularly institutional clients) generally differ from the Fund, including in terms of the different and generally more extensive services provided to the Fund, as well as other significant differences. In that regard, the Board considered that the pricing of services to institutional clients is typically based on a number of factors beyond the nature and extent of the specific services to be provided and often depends on the overall relationship between the client and its affiliates and the adviser and its affiliates. In addition, the Board considered the relative complexity and inherent risks and challenges of managing and providing other services to the Fund, as a publicly traded exchange traded fund, as compared to the Other Accounts that are institutional clients in light of differing regulatory requirements and client-imposed mandates. The Board also considered the “all-inclusive” nature of the Fund’s advisory fee structure, and the Fund expenses borne by BFA under this arrangement. The Board noted that the investment advisory fee rate under the Advisory Contract for the Fund was generally higher than the investment advisory/management fee rates for certain of the Other Accounts (particularly institutional clients) and concluded that the differences appeared to be consistent with the factors discussed.

Other Benefits to BFA and/or its Affiliates — The Board reviewed the “fallout” benefits or ancillary revenue received by BFA and/or its affiliates in connection with the services provided to the Fund by BFA, such as payment of revenue to BTC, the Fund’s securities lending agent, for loaning portfolio securities (which was included in the profit margins reviewed by the Board pursuant to BFA’s profitability methodology), and payment of advisory fees and/or administration fees to BFA and BTC (or their affiliates) in connection with any investments by the Fund in other funds for which BFA (or its affiliates) provides investment advisory services and/or administration services. The Board noted that BFA generally does not use soft dollars or consider the value of research or other services that may be provided to BFA (including its affiliates) in selecting brokers for portfolio transactions for the Fund. The Board further noted that any portfolio transactions on behalf of the Fund placed through a BFA affiliate or purchased from an underwriting syndicate in which a BFA affiliate participates, are reported to the Board pursuant to Rule 17e-1 or Rule 10f-3, as applicable, under the 1940 Act. The Board concluded that any such ancillary benefits would not be disadvantageous to the Fund’s

shareholders and thus would not alter the Board’s conclusion with respect to the appropriateness of approving the continuance of the Advisory Contract for the coming year.

The amounts and sources of distributions reported are estimates and are provided pursuant to regulatory requirements and are not being provided for tax reporting purposes. The actual amounts and sources for tax reporting purposes will depend upon the Fund’s investment experience during the year and may be subject to changes based on the tax regulations. Shareholders will receive a Form 1099-DIV each calendar year that will inform them how to report these distributions for federal income tax purposes.

This report is intended for the Fund’s shareholders. It may not be distributed to prospective investors unless it is preceded or accompanied by the current prospectus.
