The U.S. bond market declined for the 12 months ended October 31, 2018 (“reporting period”). The Bloomberg Barclays U.S. Aggregate Bond Index, a broad measure of U.S. fixed-income performance, returned -2.05%. The negative return for U.S. bonds was primarily due to a stronger U.S. economy and higher interest rates. Driven in part by the stimulative effect of federal tax reform legislation, the U.S. economy grew by 3% for the 12 months ended September 2018, its highest year-over-year growth rate in more than three years. Key components of the strengthening economy included the job market, where the unemployment rate declined to its lowest level since December 1969; industrial production, which increased at its sharpest year-over-year pace in nearly eight years; and retail sales, which accelerated for much of the reporting period before slowing in the last two months.

Faster economic growth led to higher inflation, though it remained low by historical standards. As measured by the consumer price index, the year-over-year U.S. inflation rate rose to 2.9% in mid-2018 — its fastest rate in more than six years — before falling back to 2.3% by the end of the reporting period. By comparison, the long-term historical average inflation rate is 3.3%.

In this environment, the U.S. Federal Reserve Bank (“Fed”) continued its efforts to normalize monetary policy. The Fed increased short-term interest rates four times during the reporting period, increasing its short-term interest rate target to 2.25%, the highest level in more than a decade. In addition, the Fed reduced its holdings of U.S. Treasury and mortgage-backed securities by approximately 7% during the reporting period, after quadrupling its holdings in response to the 2008 financial crisis.

Interest rates increased broadly in response to the improving economy and higher inflation. Short-term interest rates increased the most, reflecting the Fed’s actions. For example, the yield of the two-year U.S. Treasury note increased from 1.60% to 2.87% during the reporting period. Longer-term interest rates rose to a lesser degree; the yield of the 30-year U.S. Treasury bond increased from 2.88% to 3.39%. These developments led to the narrowest yield difference, or spread, between short-term and longer-term U.S. Treasury securities in more than 11 years.

Higher interest rates had the most significant impact on U.S. Treasury securities, which typically have greater sensitivity to changes in interest rates compared with other higher-yielding sectors of the bond market. Consequently, the prices of U.S. Treasury bonds declined as interest rates increased during the reporting period. U.S. Treasury inflation-protected securities also declined but to a lesser degree as the inflation rate increased.

Corporate bonds posted mixed returns for the reporting period. Despite the positive economic environment, investment-grade corporate bonds declined the most among the major bond sectors. In addition to higher interest rates, investor concerns about high corporate debt levels, a decline in average credit quality, and relatively high valuations contributed to the weakness in investment-grade corporate bonds. In contrast, high-yield corporate bonds, which have lower credit ratings, performed relatively well, as their higher yields buffered price declines. Strong investor demand for yield, lower issuance levels, and limited interest rate sensitivity contributed to the positive performance of high-yield corporate bonds.

Among securitized bonds, asset-backed securities (bonds backed by credit card receivables, auto loans, and other debt) posted positive returns for the reporting period, benefiting from their higher yields and relatively short maturities. Mortgage-backed securities, both residential and commercial, declined but to a lesser degree than the broader bond market.

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.

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 an unmanaged index that measures the performance of government and corporate securities with less than 1 year remaining to maturity.

Short-term investment-grade bonds posted positive returns for the reporting period. While longer-term bond prices generally declined in the wake of four interest rate increases by the Fed, the shortest-term bonds are the least sensitive to interest rate changes.

The Fund performed well relative to the Bloomberg Barclays Short-Term Government/Corporate Index. The Fund’s performance relative to the broader short-term bond market benefited from overweight allocations to corporate credit and securitized products, including asset-backed securities (“ABSs”) and commercial mortgage-backed securities (“CMBSs”).

In the Fund’s corporate allocation, the largest contributors to the Fund’s performance were financial and industrial bonds. In general, corporate securities benefited from strong economic growth, tax reform, and healthy earnings. High demand from yield-seeking buyers also boosted corporate bonds.

Banks were the leading contributors to the Fund’s return. These issuers made up 23% of the Fund on average during the reporting period. Despite a flattening yield curve (the difference between short-term and long-term interest rates), banks generally benefited from increasing interest rates, as revenues from longer-term, higher-rate loans outpaced increases in deposit costs. In the industrial sector, overweight allocations to both the consumer non-cyclicals and consumer cyclicals industries were beneficial to the Fund’s performance, reflecting the strong economy, a decades-low unemployment rate, and healthy consumer spending.

Among securitized products, overweight positions in ABSs and CMBSs benefited the Fund, as investors seeking yield drove demand for these products. In addition, CMBSs benefited from falling delinquency rates for commercial loans. Rising property values and the easy availability of financing helped keep commercial mortgage defaults low.

For most of the reporting period, the Fund maintained a similar or shorter interest rate sensitivity (less price sensitivity to interest rate changes) relative to the Bloomberg Barclays Short-Term Government/Corporate Index. This position reflected expectations of interest rate increases by the Fed. By the end of the reporting period, the Fund moved to a slightly longer interest rate sensitivity relative to the broader market.

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. Under normal circumstances, the effective duration of the Fund’s portfolio is expected to be 1.2 years or less, as calculated by the management team, and is not expected to exceed 1.5 years. The Fund is an actively managed exchange-traded fund that does not seek to replicate the performance of a specified index.

The inception date of the Fund was 3/3/15. The first day of secondary market trading was 3/5/15.

The Bloomberg 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.

Short-term municipal bonds posted a positive return for the reporting period. While longer-term municipal bond prices generally declined in the wake of four interest rate increases by the Fed, short-term municipal bonds are the least sensitive to interest rate changes. The Fund further maintained a defensive strategy to minimize the effect of rising interest rates.

Supply and demand were mixed. Supply surged as tax reform led to a spike in refunding issuances in late 2017, but that spike was followed by lower-than-normal issuances in 2018. Tax reform also worked to boost demand for municipal bonds, particularly from investors in higher-income tax states such as New York and California. New limits to the deductibility of state income taxes made tax-exempt municipal bonds more attractive for investors from these areas. This helped to offset a decline in demand for municipal bonds from banks and other corporations, which have a smaller incentive to invest in tax-exempt securities following the reduction of the corporate tax rate.

The Fund performed well relative to the broader market, as represented by the Bloomberg Barclays Municipal Bond: 1 Year (1-2) Index. The Fund benefited from overweight positions in bonds rated in the A and BBB categories by Standard & Poor’s, as the higher yields for this class of credit offered attractive yields relative to higher-quality AAA-rated bonds. Strong demand from income investors and a wave of reinvested coupon and principal payments helped support the market for higher-yielding municipal bonds.

To mitigate the effect of rising interest rates, the Fund maintained an overweight allocation to variable-rate demand notes (“VRDNs”). Since interest rates on VRDN securities reset periodically, bondholders can benefit from these interest rate changes. Consequently, the overweight allocation to VRDNs contributed to the Fund’s relative return.

Overweight allocations to tax-backed state and local bonds and school district bonds also contributed to the Fund’s relative performance. On the downside, an underweight allocation to pre-refunded debt securities detracted from the Fund’s relative return.

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.

The inception date of the Fund was 12/11/13. The first day of secondary market trading was 12/13/13.

The ICE BofAML 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.

Ultra-short-term bonds posted a positive return for the reporting period. While bond prices generally declined in the wake of four interest rate increases by the Fed, the shortest-term bonds are the least sensitive to interest rate changes. In addition, the Fund is designed to exhibit little share price volatility in most interest rate environments, as demonstrated during the reporting period.

The Fund performed well relative to the Bank of America Merrill Lynch 6-Month U.S. Treasury Bill Index. The largest contributor to the Fund’s return relative to the broader ultra-short-term bond market was an overweight allocation to corporate bonds. Corporate debt benefited from strong economic growth, tax reform, and healthy earnings. In addition, high demand from yield-seeking buyers boosted corporate bonds.

Within the corporate sector, banks were the largest contributors to the Fund’s return. These issuers made up 32% of the Fund on average during the reporting period. Despite a flattening yield curve (the difference between short-term and long-term interest rates), banks generally benefited from increasing interest rates, as revenues from longer-term, higher-rate loans outpaced increases in deposit costs. Bonds issued by industrial companies were also contributors to the Fund’s performance, as industrial production increased, driven by strong demand for consumer products and industrial goods.

Floating-rate notes (“floaters”), which offer some protection from rising interest rates, also contributed to the Fund’s return. Floaters periodically reset their interest rate paid to investors, therefore increasing their payments when interest rates are rising. Toward the end of the reporting period, the Fund reduced its allocation to fully valued floaters in the industrial sector in favor of more attractively valued fixed-rate securities. For example, yields on two-year Treasury notes reached their highest level since 2008 so the Fund added exposure to select maturities with attractive yields. The Fund also increased exposure to asset-backed securities, which offered an attractive risk-reward trade-off.

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 ask 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. Since shares of a fund may not trade in the secondary market until after the fund’s inception, for the period from inception to the first day of secondary market trading in shares of the fund, the NAV of the fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested 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 your 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 at the beginning of the period (or from the commencement of operations if less than 6 months) and held through the end of the period, is intended to help you understand your ongoing costs (in dollars and cents) of investing in your 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 under the heading entitled “Expenses Paid During the Period.”

Hypothetical Example for Comparison Purposes – The table also provides information about hypothetical account values and hypothetical expenses based on your 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.

Investments in issuers considered to be affiliates of the Fund during the year ended October 31, 2018, for purposes of Section 2(a)(3) of the 1940 Act, were as follows:

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 is organized as a Delaware statutory trust and is authorized to have multiple series or portfolios.

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

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 increases and decreases in net assets from operations 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.

Investment Transactions and Income Recognition: Investment 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, and payment-in-kind interest income, if any, are 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.

Foreign Currency Translation: 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 non-U.S. currencies are translated to U.S. dollars using prevailing market rates as quoted by one or more data service providers. Purchases and sales of investments, 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 investments. Such fluctuations are reflected by the Funds as a component of net realized and unrealized gain (loss) from investments for financial reporting purposes. Each Fund reports realized currency gain (loss) on foreign currency related transactions as components of net realized gain (loss) for financial reporting purposes, whereas such components are generally treated as ordinary income for U.S. federal income tax purposes.

Foreign Taxes: 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 each Fund invests. These foreign taxes, if any, are paid by each 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, 2018, if any, are disclosed in the statement of assets and liabilities.

In-kind Redemptions: For financial reporting purposes, in-kind redemptions are treated as sales of securities resulting in realized capital gains or losses to the Funds. Because such gains or losses are not taxable to the Funds and are not distributed to existing Fund shareholders, the gains or losses are reclassified from accumulated net realized gain (loss) to paid-in capital at the end of the Funds’ tax year. These reclassifications have no effect on net assets or net asset value per share.

Distributions: 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.

Recent Accounting Standards: In March 2017, the Financial Accounting Standards Board issued Accounting Standards Update “Premium Amortization on Purchase Callable Debt Securities” which amends the amortization period for certain purchased callable debt securities. Under the new guidance, premium amortization of purchased callable debt securities that have explicit, non-contingent call features and are callable at fixed prices will be amortized to the earliest call date. The guidance will be applied on a modified retrospective basis and is effective for fiscal years, and their interim periods, beginning after December 15, 2018. Management is currently evaluating the impact of this guidance to the Funds.

In August 2018, the Financial Accounting Standards Board issued Accounting Standards Update 2018-13 “Changes to the Disclosure Requirements for Fair Value Measurement” which modifies disclosure requirements for fair value measurements. The guidance is effective for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years. Management is currently evaluating the impact of this guidance to the Funds.

Indemnifications: In the normal course of business, each Fund enters into contracts that contain a variety of representations that provide general indemnification. The Funds’ maximum exposure under these arrangements is unknown because it involves future potential claims against the Funds, which cannot be predicted with any certainty.

Investment Valuation Policies: Each Fund’s investments are valued at fair value (also referred to as “market value” within the financial statements) 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. A fund determines the fair value of its financial instruments using various independent dealers or pricing services under policies approved by the Board of Trustees of the Trust (the “Board”). The BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) is the committee formed by management to develop global pricing policies and procedures and to oversee the pricing function for all financial instruments.

Fair Value Inputs and Methodologies: The following methods and inputs are used to establish the fair value of each Fund’s assets and liabilities:

If events (e.g., a company announcement, market volatility or a natural disaster) occur that are expected to materially affect the value of an investment, or in the event that application of these methods of valuation results in a price for an investment that is deemed not to be representative of the market value of such investment, or if a price is not available, the investment will be valued by the Global Valuation Committee, in accordance with policies approved by the Board as reflecting fair value (“Fair Valued Investments”). The fair valuation approaches that may be used by the Global Valuation Committee include market approach, income approach and the cost approach. Valuation techniques used under these approaches take into consideration inputs that 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 inputs, such as future cash flows, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and/or default rates.

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, regular reviews 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 and large movements in market values, and reviews of any market related activity. The pricing of all Fair Valued Investments is subsequently reported to the Board on a quarterly basis.

Fair Value Hierarchy: Various inputs are used in determining the fair value of financial instruments. These inputs to valuation techniques are categorized into a fair value hierarchy consisting of three broad levels for financial reporting purposes 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 each Fund’s investments is included in its schedule of investments.

Changes in valuation techniques may result in transfers into or out of an assigned level within the 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 a value determined for financial instruments is based on the pricing transparency of the financial instruments and is not necessarily an indication of the risks associated with investing in those securities.

Repurchase Agreements: Repurchase agreements are commitments to purchase 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 upon repurchase amount. Pursuant to the custodial undertaking associated with a tri-party repurchase arrangement, an unaffiliated third party custodian maintains accounts to

hold collateral for a fund and its counterparties. Typically, a fund and counterparty are not permitted to sell, re-pledge or use the collateral absent a default by the counterparty or the fund. In the event the counterparty defaults and the fair value of the collateral declines, a fund could experience losses, delays and costs in liquidating the collateral.

Repurchase agreements are entered into by a fund under Master Repurchase Agreements (each, an “MRA”). The MRA permits the fund, 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 open repurchase agreements as of October 31, 2018 which are subject to offset under an MRA:

Securities Lending: Each Fund may lend its 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 an approved 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 market 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 and any additional required collateral is delivered to the Fund or excess collateral is returned by the Fund, 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.

As of October 31, 2018, 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 BlackRock Fund Advisors (“BFA”), the Funds’ investment adviser, or its affiliates and is disclosed in the schedules of investments. Any non-cash collateral received cannot be sold, re-invested or pledged by the Fund, except in the event of borrower default. The securities on loan for each Fund, if any, are also disclosed in its schedule of investments. The market value of any securities on loan as of October 31, 2018 and the value of the related cash collateral are disclosed in the statements of assets and liabilities.

Securities lending transactions are entered into by a fund under Master Securities Lending Agreements (each, an “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 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, absent an event of default, the borrower can resell or re-pledge the loaned securities, and the fund can reinvest cash collateral received in connection with loaned securities.

The following table is a summary of the securities lending agreements by counterparty which are subject to offset under an MSLA as of October 31, 2018:

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, each Fund benefits from a borrower default indemnity provided by BlackRock, Inc. (“BlackRock”). BlackRock’s indemnity allows for full replacement of the securities loaned if the collateral received does not cover the value of the securities loaned in the event of borrower default. Each Fund could incur a loss if the value of an investment purchased with cash collateral falls below the market value of the loaned securities or if the value of an investment purchased with cash collateral falls below the value of the original cash collateral received. Such losses are borne entirely by each Fund.

Investment Advisory Fees: 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 (i) interest and taxes; (ii) brokerage commissions and other expenses connected with the execution of portfolio transactions; (iii) distribution fees; (iv) the advisory fee payable to BFA; and (v) litigation expenses and any extraordinary expenses (in each case as determined by a majority of the independent trustees).

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

Distributor: 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.

Securities Lending: 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, or its affiliates, 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 (excluding collateral investment fees), net of fees and other payments to and from borrowers of securities. Each 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, each Fund retains 80% of securities lending income (which excludes collateral investment fees) 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.

The share of securities lending income earned by each Fund is shown as securities lending income – affiliated – net in its statement of operations. For the year ended October 31, 2018, the Funds paid BTC the following amounts for securities lending agent services:

Officers and Trustees: Certain officers and/or trustees of the Trust are officers and/or trustees of BlackRock or its affiliates.

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

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 October 31, 2018, 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 shown as dividends – affiliated in the statement of operations.

For the year ended October 31, 2018, purchases and sales of investments, excluding in-kind transactions and short-term investments, were as follows:

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.

Management has analyzed tax laws and regulations and their application to the Funds as of October 31, 2018, inclusive of the open tax return years, and does not believe that there are any uncertain tax positions that require recognition of a tax liability in the Funds’ financial statements.

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. As of October 31, 2018, the following permanent differences attributable to undistributed capital gains were reclassified to the following accounts:

As of October 31, 2018, the tax components of accumulated net earnings (losses) were as follows:

As of October 31, 2018, the Funds had capital loss carryforwards, with no expiration dates, available to offset future realized capital gains as follows:

As of October 31, 2018, gross unrealized appreciation and depreciation based on cost of investments (including short positions and derivatives, if any) for U.S. federal income tax purposes were as follows:

In the normal course of business, each Fund invests in securities or other instruments and may enter into certain transactions, and such activities subject the Fund to various risks, including, among others, fluctuations in the market (market risk) or failure of an issuer to meet all of its obligations. The value of securities or other instruments may also be affected by various factors, including, without limitation: (i) the general economy; (ii) the overall market as well as local, regional or global political and/or social instability; (iii) regulation, taxation or international tax treaties between various countries; or (iv) currency, interest rate or price fluctuations. Each Fund’s prospectus provides details of the risks to which the Fund is subject.

Market 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 its investment in equity, fixed income and/or financial derivative instruments or by 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.

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. Securities with longer durations tend to be more sensitive to interest rate changes, usually making their price more volatile than those of 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: 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.

Municipal securities are subject to the risk that litigation, legislation or other political events, local business or economic conditions, credit rating downgrades, or the bankruptcy of the issuer could have a significant effect on an issuer’s ability to make payments of principal and/or interest or otherwise affect the value of such securities. Municipal securities can be significantly affected by political or economic changes, including changes made in the law after issuance of the securities, as well as uncertainties in the municipal market related to, taxation, legislative changes or the rights of municipal security holders, including in connection with an issuer insolvency. Municipal securities backed by current or anticipated revenues from a specific project or specific assets can be negatively affected by the discontinuance of the tax benefits supporting the project or assets or the inability to collect revenues for the project or from the assets. Municipal securities may be less liquid than taxable bonds, and there may be less publicly available information on the financial condition of municipal security issuers than for issuers of other securities.

Concentration 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 each Fund’s portfolio are disclosed in its schedule of investments.

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 shares sold in the table above.

On June 16, 2016, investors in certain iShares funds (iShares Core S&P Small-Cap ETF, iShares Russell 1000 Growth ETF, iShares Core S&P 500 ETF, iShares Russell Mid-Cap Growth ETF, iShares Russell Mid-Cap ETF, iShares Russell Mid-Cap Value ETF, iShares Select Dividend ETF, iShares Morningstar Mid-Cap ETF, iShares Morningstar Large-Cap ETF, iShares U.S. Aerospace & Defense ETF and iShares U.S. Preferred Stock ETF) filed a class action lawsuit against iShares Trust, BlackRock, Inc. and certain of its advisory affiliates, and certain directors/trustees and officers of the Funds (collectively, “Defendants”) in California State Court. The lawsuit alleges the Defendants violated federal securities laws by failing to adequately disclose in the prospectuses issued by the funds noted above the risks of using stop-loss orders in the event of a ‘flash crash’, such as the one that occurred on May 6, 2010. On September 18, 2017, the court issued a Statement of Decision holding that the Plaintiffs lack standing to assert their claims. On October 11, 2017, the court entered final judgment dismissing all of the Plaintiffs’ claims with prejudice. Plaintiffs have appealed the court’s decision.

On August 17, 2018, the SEC adopted amendments to certain disclosure requirements in Securities Act Release No. 33-10532, Disclosure Update and Simplification. The Funds have adopted the amendments pertinent to Regulation S-X in this shareholder report. The amendments impacted certain disclosure presentation on the statement of assets and liabilities, statement of changes in net assets and notes to the financial statements.

Prior year distribution information and undistributed net investment income in the statement of changes in net assets has been modified to conform to the current year presentation in accordance with the Regulation S-X changes.

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 additional disclosure in the financial statements.

We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of iShares Short Maturity Bond ETF, iShares Short Maturity Municipal Bond ETF and iShares Ultra Short-Term Bond ETF (three of the funds constituting iShares U.S. ETF Trust, hereafter collectively referred to as the “Funds”) as of October 31, 2018, the related statements of operations for the year ended October 31, 2018, the statements of changes in net assets for each of the two years in the period ended October 31, 2018, including the related notes, and the financial highlights for each of the periods indicated therein (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of each of the Funds as of October 31, 2018, the results of each of their operations for the year then ended, the changes in each of their net assets for each of the two years in the period ended October 31, 2018 and each of the financial highlights for each of the periods indicated therein in conformity with accounting principles generally accepted in the United States of America.

These financial statements are the responsibility of the Funds’ management. Our responsibility is to express an opinion on the Funds’ financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of October 31, 2018 by correspondence with the custodian, transfer agent and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinions.

We have served as the auditor of one or more BlackRock investment companies since 2000.

I. iShares Short Maturity Bond ETF, iShares Short Maturity Municipal Bond ETF and iShares Ultra Short-Term 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. At a meeting on May 11, 2018, a committee composed of all of the Independent Trustees (the “15(c) Committee”), with independent counsel, met with management and reviewed and discussed information provided in response to initial requests of the 15(c)Committee and/or their independent counsel, and requested certain additional information, which management agreed to provide. 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 24, 2018, management presented additional information to the Board relating to the continuance of the Advisory Contract, including information requested by the 15(c) Committee during its initial meeting. 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 12-14, 2018, 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. 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 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 various factors, including: (i) the expenses and performance of each Fund; (ii) the nature, extent and quality of the services provided by BFA; (iii) the costs of services provided to each Fund and profits realized by BFA and its affiliates; (iv) economies of scale; (v) the fees and services provided for other comparable funds/accounts managed by BFA and its affiliates; and (vi) other benefits to BFA and/or its affiliates. The material factors, no one of which was controlling, and conclusions that formed the basis for the Board, including the Independent Trustees, to approve the Advisory Contract are discussed below.

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, fees and expenses of another fund in which each Fund invests (if applicable), and waivers/reimbursements (if applicable) of each Fund in comparison with the same information for other ETFs (including, where applicable, funds sponsored by an “at cost” service provider),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 the 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 quarter ended December 31, 2017, to that of relevant comparison fund(s) 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 the Funds manage each 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 reference benchmark. Such periodic comparative performance information, including additional detailed information as requested by the Board, was also considered. The Board noted that the Funds generally performed in line with expectations relative to each Fund’s reference benchmark.

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, technology, portfolio management, product design and quality, compliance and risk management, global public policy 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 support 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 relevant officers and other employees of BFA (and its affiliates) 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 12-14, 2018 meeting and throughout the year, and matters related to BFA’s portfolio compliance policies and procedures.

Based on review of this information, and the performance information discussed above, the Board concluded that the nature, extent and quality of services provided 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 Fund and Profits Realized by BFA and its Affiliates: The Board reviewed information about the profitability to BlackRock in managing the Funds, based on the fees payable to BFA and its affiliates (including fees under the Advisory Contract), and 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 and the Board had focused on the methodology and profitability presentation during their meetings. The Board further noted that it considered the supplemental information the 15(c) Committee requested, which BlackRock provided, regarding the methodology. The Board discussed the sources of direct and ancillary revenue with management, including the revenues to BTC, a BlackRock affiliate, from securities lending by the Funds. The Board also discussed BFA’s profit margin as reflected in the Funds’ 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 Funds and BFA and/or its affiliates, if any, were within a reasonable range in light of the factors and other information 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 by the 15(c) Committee and the Board during their meetings and addressed by management. The 15(c) Committee and the Board 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 showed 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 15(c) Committee and the Board reviewed information provided by BFA regarding the sharing of scale benefits with the iShares funds through various means, including, as applicable, 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 noted that the Advisory Contract for the Funds did not provide for breakpoints in the Funds’ investment advisory fee rates as the assets of the Funds increase. However, the Board noted that a breakpoint structure for the Funds may be appropriate should material economies of scale exist in the future that are not otherwise shared, 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 of the sharing of scale benefits, as well as the other factors considered at the meeting, the Board concluded that the information concerning the sharing of scale benefits 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 (collectively, 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 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 ETFs, as compared to the Other Accounts, particularly those that are institutional clients, in light of differing regulatory requirements and client-imposed mandates. The Board also acknowledged management’s assertion that, for certain iShares funds, and for client segmentation purposes, BlackRock has launched an iShares fund that may provide a similar investment exposure at a lower investment advisory fee rate. The Board also considered the “all-inclusive” nature of the Funds’ advisory fee structure, and the Funds’ expenses borne by BFA under this arrangement. The Board noted that the investment advisory fee rates under the Advisory Contract for the Funds 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 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 (or its 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 also noted the revenue received by BFA and/or its affiliates pursuant to an agreement that permits a service provider to use certain portions of BlackRock’s technology platform to service accounts managed by BFA and/or its affiliates, including the iShares funds. 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 (including associated commissions) 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 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.

Conclusion: Based on a review of the factors described above, as well as such other factors as deemed appropriate by the Board, the Board, including all of the Independent Trustees, determined that the Funds’ investment advisory fee rates under the Advisory Contract do not constitute fees that are 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 to approve the continuance of the Advisory Contract for the coming year.

The amounts and sources of distributions reported in this notice are for financial reporting purposes and are not being provided for tax reporting purposes. The actual amounts and character of the distributions for tax reporting purposes will be reported to shareholders on Form 1099-DIV which is sent to shareholders shortly after calendar year-end.

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 ask on the primary securities exchange on which 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 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.

Premium/discount information for the Funds covering the most recently completed calendar year and the most recently completed calendar quarters since that year (or since the Fund began trading, if shorter) is publicly accessible, free of charge, at www.iShares.com.

The following information shows the frequency of distributions of premiums and discounts for the Funds for the immediately preceding five calendar years (or from the date a Fund began trading on the secondary market, if less than five years) through the date of the most recent calendar quarter-end. Each line in each table shows the number of trading days in which the Fund traded within the premium/discount range indicated. Premium/discount ranges with no trading days are omitted. 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 all of the funds within the Exchange-Traded Fund Complex, which consists of 343 funds as of October 31, 2018. With the exception of Robert S. Kapito, Mark K. Wiedman, Charles Park, Martin Small and Benjamin Archibald, the address of each Trustee and officer is c/o BlackRock, Inc., 400 Howard Street, San Francisco, CA 94105.

The iShares Inflation Hedged Corporate Bond ETF (the “Fund”) seeks to mitigate the inflation 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 inflation risk of the underlying fund by holding inflation swaps.

For the fiscal period ended 10/31/18, the Fund did not have six months of performance and therefore line graphs and portfolio management commentary are not presented.

The inception date of the Fund was 5/8/18. The first day of secondary market trading was 5/10/18.

The Markit iBoxx^® USD Liquid Investment Grade Inflation Hedged Index is an unmanaged index that is designed to reflect the inflation hedged performance of U.S. dollar-denominated investment-grade 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.

The inception date of the Fund was 5/27/14. The first day of secondary market trading was 5/28/14.

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

Favorable credit and supply-and-demand conditions meant high-yield bonds posted a positive return for the reporting period. Both the Fund’s securities and the interest rate hedge contributed to the Fund’s return.

Rising interest rates during the reporting period meant positive returns from hedging activity, which was the largest contributor to the Fund’s return. Typically, increasing interest rates reduce the value of existing bonds, meaning a rise in interest rates detracts from bond fund performance. Conversely, falling interest rates usually serve to increase bond prices. An interest rate hedged fund attempts to avoid these fluctuations by offsetting interest rate risk, primarily using interest rate swaps and Treasury futures contracts.

The Fund’s interest rate hedge seeks near-zero interest rate sensitivity. Consequently, the Fund’s return was minimally affected by interest rate fluctuations during the reporting period. With interest rate sensitivity hedged, the Fund fluctuated based on direct exposure to the yield premium of high-yield corporate bonds, independent of rising interest rates.

High-yield corporate bonds benefited from the strength of the U.S. economy, record high corporate profits, and corporate tax cuts during the reporting period. In addition, strong investor demand for yield helped the performance of corporate bonds at the same time that the issuance of new high-yield bonds declined. Issuance declined as interest rates rose, making borrowing less attractive, and as companies turned to other sources of capital.

The 12-month high-yield corporate bond default rate stood at 3.4% in August 2018. That’s particularly notable because the level of corporate debt to economic growth reached a record high at the end of 2017. Such high levels of corporate debt in the past have been associated with high default rates.

In terms of the Fund’s underlying securities, pharmaceutical bonds contributed the most to the Fund’s performance, amid a wave of new drug approvals and a more innovation-friendly Food and Drug Administration. Healthcare bonds also contributed meaningfully to the Fund’s performance, due to strong performance by healthcare providers that experienced rising procedure and patient treatment volumes.

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.

The inception date of the Fund was 5/27/14. The first day of secondary market trading was 5/28/14.

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

The Fund posted a positive return even as interest rates rose for the reporting period, as interest rate hedging offset the decline in investment-grade corporate bond prices. The interest rate hedge was the largest contributor to the Fund’s return. Typically, increasing interest rates reduce the value of existing bonds, meaning a rise in interest rates detracts from bond fund performance. Conversely, falling interest rates usually serve to increase bond prices. An interest rate hedged fund attempts to avoid these fluctuations by offsetting interest rate risk, primarily using interest rate swaps and Treasury futures contracts.

The Fund’s interest rate hedge seeks near-zero interest rate sensitivity and was successful within its targeted range. Consequently, the Fund’s return was minimally affected by interest rate fluctuations during the reporting period. With interest rate sensitivity hedged, the Fund fluctuated based on direct exposure to the yield premium of corporate bonds, independent of rising interest rates.

In terms of the Fund’s underlying securities, industrial bonds, which made upapproximately 64% of the Fund on average during the reporting period, were the largest detractors from the Fund’s return. Within the sector, companies in the pharmaceuticals and food and beverage industries detracted meaningfully from the Fund’s performance. Global food and beverage companies were negatively affected by currency fluctuations, especially in emerging markets, while pharmaceutical companies were affected by issues ranging from concerns over drug pricing to global regulations for multinational drug manufacturers.

Other detractors included the technology industry, which declined late in the reporting period amid investor concerns about future growth prospects, and energy, which declined despite rising energy prices, as the futures market reflected modest expectations for oil prices. Acquisitions among heavily indebted cable companies and weak car and truck sales despite pricing discounts led to poor performance in the communications and consumer cyclicals industries, which detracted from the Fund’s return.

Bonds in the financial sector also detracted significantly from the Fund’s return, driven by weak performance in the banking industry. Banks contended with deposit pricing pressures that could restrict growth in lending profits, as well as trade disputes and rising tariffs that dampened long-term growth expectations.

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 the Period.”

Hypothetical Example for Comparison Purposes – The table also provides information about hypothetical account values and hypothetical expenses based on your 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.

Balances Reported in the Statements of Assets and Liabilities for Centrally Cleared Swaps

As of October 31, 2018, the fair values of derivative financial instruments located in the Statement of Assets and Liabilities were as follows:

For the year ended October 31, 2018, the effect of derivative financial instruments in the Statement of Operations was as follows:

For more information about the Fund’s investment risks regarding derivative financial instruments, refer to the Notes to Financial Statements.

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 iShares fund (an “underlying fund”). The financial statements and schedules of investments for the underlying funds should be read in conjunction with the Funds’ financial statements.

Recent Accounting Standards: In August 2018, the Financial Accounting Standards Board issued Accounting Standards Update 2018-13 “Changes to the Disclosure Requirements for Fair Value Measurement” which modifies disclosure requirements for fair value measurements. The guidance is effective for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years. Management is currently evaluating the impact of this guidance to the Funds.

Fair Value Inputs and Methodologies: The following methods and inputs are used to establish the fair value of each Fund’s assets and liabilities:

The following table is a summary of the securities lending agreements by counterparty which are subject to offset under an MSLA as of October 31, 2018:

Futures Contracts: U.S. Treasury futures are used by the iShares Inflation Hedged Corporate Bond ETF to mitigate the potential impact of interest rates on the performance of the bonds held by the Fund or its underlying fund. Futures contracts are standardized, exchange-traded agreements to buy or sell a specific quantity of an underlying instrument at a set price on a future date. Depending on the terms of a contract, a futures contract is settled either through physical delivery of the underlying instrument on the settlement date or by payment of a cash amount on the settlement date.

Upon entering into a futures contract, a 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. Securities deposited as initial margin, if any, are designated in the schedule of investments and cash deposited, if any, is shown as cash pledged for futures contracts in the statement of assets and liabilities.

Pursuant to the contract, a fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in market value of the contract (“variation margin”). Variation margin is recorded as unrealized appreciation or depreciation and, if any, shown as variation margin receivable or payable on futures contracts in the statement of assets and liabilities. When the contract is closed, a realized gain or loss is recorded in the statement of operations equal to the difference between the notional amount of the contract at the time it was opened and the notional amount at the time it was closed. Losses may arise if the notional 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 involves the risk of an imperfect correlation in the movements in the price of futures contracts and the assets underlying such contracts.

Swaps: Swaps are financial agreements to exchange cash flows in which one party pays a stream of interest payments, either fixed or floating, in exchange for another party’s stream of interest payments, either fixed or floating, on the same notional amount for a specified period of time. The iShares Inflation Hedged Corporate Bond ETF uses inflation swaps to mitigate the potential impact of inflation on the performance of the bonds held by the Fund or its underlying fund. The iShares Interest Rate Hedged High Yield Bond ETF and iShares Interest Rate Hedged Corporate Bond ETF use interest rate swaps to mitigate the potential impact of interest rates on the performance of the bonds held by each Fund or its underlying fund.

Swap agreements are privately negotiated in the over-the-counter market and may be entered into as a bilateral contract or centrally cleared (“centrally cleared swaps”). Each Fund enters into centrally cleared 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 schedule of investments and cash deposited is shown as cash pledged for centrally cleared swaps on the

statement of assets and liabilities. The daily change in valuation of centrally cleared swaps is recorded as variation margin receivable or payable on centrally cleared swaps in the statement of assets and liabilities. Payments received from (paid to) the counterparty, including at termination, are recorded as realized gains (losses) in the statement of operations. Upfront payments and receipts are shown as swap premiums paid and swap premiums received in the statement of assets and liabilities and represent compensating factors between the stated terms of the swap agreement and prevailing market conditions (interest rate spreads and other relevant factors), at the time the swap was entered into by the Fund. These upfront payments and receipts are amortized over the term of the contract as a realized gain (loss) in the statement of the 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.

For the iShares Inflation Hedged Corporate Bond ETF, BFA has contractually agreed to waive a portion of its investment advisory fee for the Fund through February 28, 2023 so that the Fund’s total annual operating expenses after fee waiver is equal to the acquired fund fees and expenses attributable to the Fund’s investment in the iShares iBoxx $ Investment Grade Corporate Bond ETF (“LQD”), after taking into account any fee waivers by LQD, plus 0.05%.

For the iShares Interest Rate Hedged High Yield Bond ETF, BFA has contractually agreed to waive a portion of its investment advisory fee for the Fund through February 28, 2022 so that the Fund’s total annual operating expenses after fee waiver is equal to the acquired fund fees and expenses attributable to the Fund’s investment in the iShares iBoxx $ High Yield Corporate Bond ETF (“HYG”), after taking into account any fee waivers by HYG, plus 0.05%.

For the iShares Interest Rate Hedged Corporate Bond ETF, BFA has contractually agreed to waive a portion of its investment advisory fee for the Fund through February 28, 2022 so that the Fund’s total annual operating expenses after fee waiver is equal to the acquired fund fees and expenses attributable to the Fund’s investment in LQD, after taking into account any fee waivers by LQD, plus 0.10%.

Officers and Trustees: Certain officers and/or trustees of the Trust are officers and/or trustees of BlackRock or its affiliates.

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

For the year ended October 31, 2018, purchases and sales of investments, excluding in-kind transactions and short-term investments, were as follows:

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. As of October 31, 2018, the following permanent differences attributable to the use of equalization and realized gains (losses) from in-kind redemptions, were reclassified to the following accounts:

As of October 31, 2018, the tax components of accumulated net earnings (losses) were as follows:

As of October 31, 2018, the Funds had capital loss carryforwards, with no expiration dates, available to offset future realized capital gains as follows:

For the year ended October 31, 2018, the Funds utilized the following amounts of their capital loss carryforwards as follows:

rate changes, usually making their price more volatile than those of 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.

Prior year distribution information in the statement of changes in net assets has been modified to conform to the current year presentation in accordance with the Regulation S-X changes.

We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of iShares Inflation Hedged Corporate Bond ETF, iShares Interest Rate Hedged High Yield Bond ETF and iShares Interest Rate Hedged Corporate Bond ETF (three of the funds constituting iShares U.S. ETF Trust, hereafter collectively referred to as the “Funds”) as of October 31, 2018, the related statements of operations and changes in net assets for each of the periods indicated in the table below, including the related notes, and the financial highlights for each of the periods indicated therein (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of each of the Funds as of October 31, 2018, the results of each of their operations and changes in each of their net assets for each of the periods indicated in the table below and each of the financial highlights for each of the periods indicated therein in conformity with accounting principles generally accepted in the United States of America.

We have served as the auditor of one or more BlackRock investment companies since 2000.

The Funds hereby designate the following amounts of distributions from direct federal obligation interest for the fiscal year ended October 31, 2018:

The following distribution amounts are hereby designated for the fiscal year ended October 31, 2018:

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. At a meeting on May 11, 2018, a committee composed of all of the Independent Trustees (the “15(c) Committee”), with independent counsel, met with management and reviewed and discussed information provided in response to initial requests of the 15(c) Committee and/or their independent counsel, and requested certain additional information, which management agreed to provide. 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 24, 2018, management presented additional information to the Board relating to the continuance of the Advisory Contract, including information requested by the 15(c) Committee during its initial meeting. 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 12-14, 2018, 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. 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 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 various factors, including: (i) the expenses and performance of the Fund; (ii) the nature, extent and quality of the services provided by BFA; (iii) the costs of services provided to the Fund and profits realized by BFA and its affiliates; (iv) economies of scale; (v) the fees and services provided for other comparable funds/accounts managed by BFA and its affiliates; and (vi) other benefits to BFA and/or its affiliates. The material factors, no one of which was controlling, and conclusions that formed the basis for the Board, including the Independent Trustees, to approve the Advisory Contract are discussed below.

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, fees and expenses of another fund in which the Fund invests (if applicable), and waivers/reimbursements (if applicable) of the Fund in comparison with the same information for other ETFs (including, where applicable, funds sponsored by an “at cost” service provider), 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 the 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.

Because the Fund had not commenced operations as of December 31, 2017, the Board did not review any performance information for the Fund.

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, technology, portfolio management, product design and quality, compliance and risk management, global public policy 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 support 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 relevant officers and other employees of BFA (and its affiliates) 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 12-14, 2018 meeting and throughout the year, and matters related to BFA’s portfolio compliance policies and procedures.

Based on review of this information, and the performance information discussed above, the Board concluded that the nature, extent and quality of services provided 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 of the iShares complex to BlackRock, based on the fees payable to BFA and its affiliates (including fees under the Advisory Contract), and other sources of revenue and expense to BFA and its affiliates from the iShares funds’ operations for the last calendar year. The Board did not consider the profitability of the Fund to BFA and its affiliates since the Fund had not commenced operations as of December 31, 2017. The Board reviewed BlackRock’s profitability methodology for the iShares funds, noting that the 15(c) Committee and the Board had focused on the methodology and profitability presentation during their meetings. The Board noted that the 15(c)Committee had focused on the methodology and profitability presentation during its meetings. The Board further noted that it considered the supplemental information the 15(c) Committee requested, which BlackRock provided, regarding the methodology. The Board discussed the sources of direct and ancillary revenue with management, including the revenues to BTC, a BlackRock

affiliate, from securities lending by the iShares funds. The Board noted that it expects to receive profitability information from BFA on at least an annual basis following the Fund’s launch and thus be in a position to evaluate whether any new or additional breakpoints or other adjustments in Fund fees would be appropriate.

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 by the 15(c) Committee and the Board during their meetings and addressed by management. The 15(c) Committee and the Board 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 showed 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 15(c) Committee and the Board reviewed information provided by BFA regarding the sharing of scale benefits with the iShares funds through various means, including, as applicable, 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 noted that the Advisory Contract for the Fund did not provide for breakpoints in the Fund’s investment advisory fee rate as the assets of the Fund increase. However, the Board noted that a breakpoint structure for the Fund may be appropriate should material economies of scale exist in the future that are not otherwise shared, 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 (collectively, 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 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 ETF, as compared to the Other Accounts, particularly those that are institutional clients, in light of differing regulatory requirements and client-imposed mandates. The Board also acknowledged management’s assertion that, for certain iShares funds, and for client segmentation purposes, BlackRock has launched an iShares fund that may provide a similar investment exposure at a lower investment advisory fee rate. The Board also considered the “all-inclusive” nature of the Fund’s advisory fee structure, and the Fund’s 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: Except as noted below, the Board did not consider the “fallout” benefits or ancillary revenue to be received by BFA and/or its affiliates in connection with the services to be provided to the Fund by BFA, since the Fund has not commenced operations as of December 31, 2017. The Board reviewed the “fallout” benefits or ancillary revenue received by BFA and/or its affiliates in connection with the services provided to other iShares funds by BFA, such as payment of revenue to BTC, the securities lending agent to the iShares funds, 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 (or its affiliates) in connection with any investments by the iShares funds in other funds for which BFA (or its affiliates) provides investment advisory services and/or administration services. The Board also noted the revenue received by BFA and/or its affiliates pursuant to an agreement that permits a service provider to use certain portions of BlackRock’s technology platform to service accounts managed by BFA and/or its affiliates, including the iShares funds. 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 iShares funds. The Board further noted that any portfolio transactions on behalf of the iShares funds placed through a BFA affiliate or purchased from an underwriting syndicate in which a BFA affiliate participates (including associated commissions) 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 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.

Conclusion: Based on a review of the factors described above, as well as such other factors as deemed appropriate by the Board, the Board, including all of the Independent Trustees, determined that the 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 to approve the continuance of the Advisory Contract for the coming year.

continuance of the Advisory Contract, including information requested by the 15(c) Committee during its initial meeting. 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 12-14, 2018, 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. 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 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 various factors, including: (i) the expenses and performance of each Fund; (ii) the nature, extent and quality of the services provided by BFA; (iii) the costs of services provided to each Fund and profits realized by BFA and its affiliates; (iv) economies of scale; (v) the fees and services provided for other comparable funds/accounts managed by BFA and its affiliates; and (vi) other benefits to BFA and/or its affiliates. The material factors, no one of which was controlling, and conclusions that formed the basis for the Board, including the Independent Trustees, to approve the Advisory Contract are discussed below.

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, fees and expenses of another fund in which each Fund invests (if applicable), and waivers/reimbursements (if applicable) of each Fund in comparison with the same information for other ETFs (including, where applicable, funds sponsored by an “at cost” service provider), 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 the 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 higher 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.

Costs of Services Provided to Fund and Profits Realized by BFA and its Affiliates: The Board reviewed information about the profitability to BlackRock in managing the Funds, based on the fees payable to BFA and its affiliates (including fees under the Advisory Contract), and 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 the15(c) Committee and the Board had focused on the methodology and profitability presentation during their meetings. The Board further noted that it considered the supplemental information the 15(c) Committee requested, which BlackRock provided, regarding the methodology. The Board discussed the sources of direct and ancillary revenue with management, including the revenues to BTC, a BlackRock affiliate, from securities lending by the Funds. The Board also discussed BFA’s profit margin as reflected in the Funds’ profitability analysis and reviewed information regarding potential economies of scale (as discussed below).

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 by the 15(c) Committee and the Board during their meetings and addressed by management. The 15(c) Committee and the Board 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 showed 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 15(c) Committee and the Board reviewed information provided by BFA regarding the sharing of scale benefits with the iShares funds through various means, including, as applicable, 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 noted that the Advisory Contract for the Funds did not provide for breakpoints in the Funds’ investment advisory fee rates as the assets of the Funds increase. However, the Board noted that a breakpoint structure for the Funds may be appropriate should material economies of scale exist in the future that are not otherwise shared, 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 (collectively, 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 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 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 ETFs, as compared to the Other Accounts, particularly those that are institutional clients, in light of differing regulatory requirements and client-imposed mandates. The Board also acknowledged management’s assertion that, for certain iShares funds, and for client segmentation purposes, BlackRock has launched an iShares fund that may provide a similar investment exposure at a lower investment advisory fee rate.

The Board noted that the investment advisory fee rates under the Advisory Contract for the Funds 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.

Investments in issuers considered to be affiliates of the Fund during the year ended February 28, 2018, for purposes of Section 2(a)(3) of the 1940 Act were as follows:

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.

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 by the Global Valuation Committee, in accordance with policies approved by the Board. The fair valuation approaches that may be utilized by the Global Valuation Committee to determine fair value include market approach, income approach and the cost approach. The valuation techniques used under these approaches take into consideration inputs that 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 inputs, such as future cash flows, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and/or default rates. Valuations based on such inputs 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.

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 to valuation techniques are categorized into a fair value hierarchy consisting of three broad levels for financial reporting purposes as follows:

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, and payment-in-kind interest income, if any, are 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.

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 an approved 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.

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 28, 2018, 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. Any non-cash collateral received cannot be sold, re-invested or pledged by the Fund, except in the event of borrower default. 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 28, 2018 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.

investment purchased with cash collateral falls below the value of the loaned securities or if the value of an investment purchased with cash collateral falls below the value of the original 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 February 28, 2018:

In March 2017, the Financial Accounting Standards Board issued Accounting Standards Update “Premium Amortization on Purchase Callable Debt Securities” which amends the amortization period for certain purchased callable debt securities. Under the new guidance, premium amortization of purchased callable debt securities that have explicit, non-contingent call features and are callable at fixed prices will be amortized to the earliest call date. The guidance will be applied on a modified retrospective basis and is effective for fiscal years, and their interim periods, beginning after December 15, 2018. Management is currently evaluating the impact of this guidance to the Funds.

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 (i) interest and taxes; (ii) brokerage commissions and other expenses connected with the execution of portfolio transactions; (iii) distribution fees; (iv) the advisory fee payable to BFA; and (v) litigation expenses and any extraordinary expenses (in each case as determined by a majority of the independent trustees).

For its investment advisory services to the iShares iBoxx $ High Yield Corporate Bond ETF, BFA is entitled to an annual investment advisory fee, accrued daily and paid monthly by the Fund, 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:

(“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 (excluding collateral investment fees), net of fees and other payments to and from borrowers of securities. 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 February 28, 2018, 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.

For the year ended February 28, 2018, 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 “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 February 28, 2018 were as follows:

In-kind transactions (see Note 4) for the year ended February 28, 2018 were as follows:

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.

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 a fund may suffer through holding market positions in the face of market movements. A fund is exposed to market risk by its investment in equity, fixed income and/or financial derivative instruments or by 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.

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: differences in accounting, auditing and financial reporting standards; more substantial governmental involvement in the economy; higher inflation rates, greater social, economic and political uncertainties; possible nationalization or expropriation of assets; less availability of public information about issuers; imposition of withholding or other taxes; higher transaction and custody costs and delays in settlement procedures; and lower level of regulation of the securities markets and issuers. Non-U.S. securities may be less liquid, more difficult to value, and have greater price volatility due to exchange rate fluctuations. These and other risks are heightened for investments in issuers from countries with less developed capital markets.

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. Securities with longer durations tend to be more sensitive to interest rate changes, usually making their prices more volatile than those of securities with shorter durations. 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 (commonly referred to as “junk bonds”) or are unrated may be deemed speculative, involve greater levels of risk than higher-rated securities of similar maturity and are more likely to default. High yield securities may be issued by less creditworthy issuers, and issuers of high yield securities may be unable to meet their interest or principal payment obligations. High yield securities are subject to extreme price fluctuations, may be less liquid than higher rated fixed-income securities, even under normal economic conditions, and frequently have redemption features.

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 February 28, 2018, attributable to the expiration of capital loss carryforwards and realized gains (losses) from in-kind redemptions, were reclassified to the following accounts:

The tax character of distributions paid during the years ended February 28, 2018 and February 28, 2017 was as follows:

As of February 28, 2018, the tax components of accumulated net earnings (losses) were as follows:

As of February 28, 2018, the Funds had non-expiring capital loss carryforwards available to offset future realized capital gains as

For the year ended February 28, 2018, the iShares iBoxx $ Investment Grade Corporate Bond ETF utilized $18,455,658 of its

As of February 28, 2018, gross unrealized appreciation and depreciation based on cost of investments (including short positions and derivatives) for U.S. federal income tax purposes were as follows:

Management has analyzed tax laws and regulations and their application to the Funds as of February 28, 2018, 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.

On June 16, 2016, investors (the “Plaintiffs”) in certain iShares funds (iShares Core S&P Small-Cap ETF, iShares Russell 1000 Growth ETF, iShares Core S&P 500 ETF, iShares Russell Mid-Cap Growth ETF, iShares Russell Mid-Cap ETF, iShares Russell Mid-Cap Value ETF, iShares Select Dividend ETF, iShares Morningstar Mid-Cap ETF, iShares Morningstar Large-Cap ETF, iShares U.S. Aerospace & Defense ETF and iShares U.S. Preferred Stock ETF) filed a putative class action lawsuit against iShares Trust, BlackRock, Inc. and certain of its advisory affiliates, and certain directors/trustees and officers of the Funds (collectively, “Defendants”) in California State Court. The lawsuit alleges the Defendants violated federal securities laws by failing to adequately disclose in the prospectuses issued by the funds noted above the risks of using stop-loss orders in the event of a ‘flash crash’, such as the one that occurred on May 6, 2010. On September 18, 2017, the court issued a Statement of Decision holding that the Plaintiffs lack standing to assert their claims. On October 11, 2017, the court entered final judgment dismissing all of the Plaintiffs’ claims with prejudice. Plaintiffs have appealed the court’s decision.

We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of iShares iBoxx $ High Yield Corporate Bond ETF and iShares iBoxx $ Investment Grade Corporate Bond ETF (two of the funds constituting iShares Trust, hereafter collectively referred to as the “Funds”) as of February 28, 2018, the related statements of operations for the year ended February 28, 2018, the statements of changes in net assets for each of the two years in the period ended February 28, 2018, including the related notes, and the financial highlights for each of the five years in the period ended February 28, 2018 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of each of the Funds as of February 28, 2018, the results of each of their operations for the year then ended, the changes in each of their net assets for each of the two years in the period ended February 28, 2018 and each of the financial highlights for each of the five years in the period ended February 28, 2018 in conformity with accounting principles generally accepted in the United States of America.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of February 28, 2018 by correspondence with the custodian, transfer agent and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinions.

We have served as the auditor of one or more BlackRock investment companies since 2000.

The iShares Interest Rate Hedged Long-Term Corporate Bond ETF (the “Fund”) (formerly the iShares Interest Rate Hedged 10+ Year Credit Bond ETF) seeks to mitigate the interest rate risk of a portfolio composed of U.S. dollar-denominated investment-grade corporate bonds 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 Long-Term Corporate Bond ETF (formerly 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.

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 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 ICE Q70A Custom Index is an unmanaged index that consists of the ICE BofAML 10+ Year US Corporate Index plus interest rate swaps that intend to hedge the interest rate exposure of the ICE BofAML 10+ Year US Corporate Index.

The Fund posted a positive return for the reporting period, as interest rate hedging offset the increase in interest rates and decline in long-term investment-grade corporate bond prices. The interest rate hedge was the largest contributor to the Fund’s return. Increasing interest rates reduce the value of existing bonds, meaning a rise in interest rates typically detracts from bond fund performance. Conversely, falling interest rates usually serve to increase bond prices. An interest rate hedged fund attempts to avoid these fluctuations by offsetting interest rate risk, primarily using interest rate swaps and Treasury futures contracts.

In terms of the Fund’s underlying securities, industrial bonds, which made upapproximately 62% of the Fund on average during the reporting period, were the largest detractors from the Fund’s return. Within the sector, consumer non-cyclical companies detracted the mostfrom the Fund’s performance, particularly in the pharmaceuticals and food and beverage industries. Global food and beverage companies were negatively affected by currency fluctuations, especially in emerging markets, while pharmaceutical companies were affected by issues ranging from concerns over drug pricing to global regulations for multinational drug manufacturers. The utilities sector also detracted from the Fund’s performance, as Moody’s Investors Service placed a negative outlook on the regulated utilities industry. Bonds issued by energy companies declined despite rising energy prices. Acquisitions in the heavily indebted cable industry and credit downgrades for two large multinational manufacturing companies also detracted from the Fund’s performance in the communications and capital goods industries.

For more information about the Fund’s investment risks regarding derivative financial instruments, refer to the Notes to Financial Statements.

Currently the Fund seeks to achieve its investment objective by investing a substantial portion of its assets in an iShares fund (an “underlying fund”). The financial statements and schedule of investments for the underlying fund should be read in conjunction with the Fund’s financial statements.

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 increases and decreases in net assets from operations 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.

In-kind Redemptions: For financial reporting purposes, in-kind redemptions are treated as sales of securities resulting in realized capital gains or losses to the Fund. Because such gains or losses are not taxable to the Fund and are not distributed to existing Fund shareholders, the gains or losses are reclassified from accumulated net realized gain (loss) to paid-in capital at the end of the Fund’s tax year. These reclassifications have no effect on net assets or net asset value per share.

Distributions: 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.

Indemnifications: In the normal course of business, the Fund enters into contracts that contain a variety of representations that provide general indemnification. The Fund’s maximum exposure under these arrangements is unknown because it involves future potential claims against the Fund, which cannot be predicted with any certainty.

Investment Valuation Policies: The Fund’s investments are valued at fair value (also referred to as “market value” within the financial statements) 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. A fund determines the fair value of its financial instruments using various independent dealers or pricing services under policies approved by the Board of Trustees of the Trust (the “Board”). The BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) is the committee formed by management to develop global pricing policies and procedures and to oversee the pricing function for all financial instruments.

Fair Value Inputs and Methodologies: The following methods and inputs are used to establish the fair value of the Fund’s assets and liabilities:

is not available, the investment will be valued by the Global Valuation Committee, in accordance with policies approved by the Board as reflecting fair value (“Fair Valued Investments”). The fair valuation approaches that may be used by the Global Valuation Committee include market approach, income approach and the cost approach. Valuation techniques used under these approaches take into consideration inputs that 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 inputs, such as future cash flows, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and/or default rates.

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.

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.

Securities Lending: The Fund may lend its 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 an approved 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 market 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 and any additional required collateral is delivered to the Fund or 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.

As of October 31, 2018, 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 BlackRock Fund Advisors (“BFA”), the Fund’s investment adviser, or its affiliates and is disclosed in the schedule of investments. Any non-cash collateral received cannot be sold, re-invested or pledged by the Fund, except in the event of borrower default. The securities on loan for the Fund, if any, are also disclosed in its schedule of investments. The market value of any securities on loan as of October 31, 2018 and the value of the related cash collateral are disclosed in the statement of assets and liabilities.

The following table is a summary of the securities lending agreements by counterparty which are subject to offset under an MSLA as of October 31, 2018:

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, Inc. (“BlackRock”). BlackRock’s indemnity allows for full replacement of the securities loaned if the collateral received does not cover the value of the securities loaned in the event of borrower default. The Fund could incur a loss if the value of an investment purchased with cash collateral falls below the market value of the loaned securities or if the value of an investment purchased with cash collateral falls below the value of the original cash collateral received. Such losses are borne entirely by the Fund.

Swap agreements are privately negotiated in the over-the-counter market and may be entered into as a bilateral contract or centrally cleared (“centrally cleared swaps”). The Fund enters into centrally cleared 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 shown as cash pledged for centrally cleared swaps on the statement of assets and liabilities. The daily change in valuation of centrally cleared swaps is recorded as variation margin receivable or payable on centrally cleared swaps in the statement of assets and liabilities. Payments received from (paid to) the counterparty, including at termination, are recorded as realized gains (losses) in the statement of operations. Upfront payments and receipts are shown as swap premiums paid and swap premiums received in the statement of assets and liabilities and represent compensating factors between the stated terms of the swap agreement and prevailing market conditions (interest rate spreads and other relevant factors), at the time the swap was entered into by the Fund. These upfront payments and receipts are amortized over the term of the contract as a realized gain (loss) in the statement of the operations.

Investment Advisory Fees: 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 (i) interest and taxes; (ii) brokerage commissions and other expenses connected with the execution of portfolio transactions; (iii) distribution fees; (iv) the advisory fee payable to BFA; and (v) litigation expenses and any extraordinary expenses (in each case as determined by a majority of the independent trustees).

For its investment advisory services to the Fund, BFA is entitled to an annual investment advisory fee of 0.35%, accrued daily and paid monthly by the Fund, based on the average daily net assets of the Fund.

Expense Waivers: A fund may incur its pro rata share of fees and expenses attributable to its investments in other investment companies (“acquired fund fees and expenses”). The total of the investment advisory fee and acquired fund fees and 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, 2022 so that the Fund’s total annual operating expenses after fee waiver is equal to the acquired fund fees and expenses attributable to the Fund’s investment in the iShares Long-Term Corporate Bond ETF (“IGLB”), after taking into account any fee waivers by IGLB, plus 0.10%.

Distributor: 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.

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, or its affiliates, 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 (excluding collateral investment fees), net of fees and other payments to and from borrowers of securities. 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 (which excludes collateral investment fees) 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.

The share of securities lending income earned by the Fund is shown as securities lending income – affiliated – net in its statement of operations. For the year ended October 31, 2018, the Fund paid BTC $10,339 for securities lending agent services.

Officers and Trustees: Certain officers and/or trustees of the Trust are officers and/or trustees of BlackRock or its affiliates.

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

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 shown as dividends – affiliated in the statement of operations.

For the year ended October 31, 2018, purchases and sales of investments, excluding in-kind transactions and short-term investments, were as follows:

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.

Management has analyzed tax laws and regulations and their application to the Fund as of October 31, 2018, inclusive of the open tax return years, and does not believe that there are any uncertain tax positions that require recognition of a tax liability in the Fund’s financial statements.

As of October 31, 2018, the tax components of accumulated net earnings (losses) were as follows:

For the year ended October 31, 2018, the Fund utilized $758,135 of its capital loss carryforwards.

In the normal course of business, the Fund invests in securities or other instruments and may enter into certain transactions, and such activities subject the Fund to various risks, including, among others, fluctuations in the market (market risk) or failure of an issuer to meet all of its obligations. The value of securities or other instruments may also be affected by various factors, including, without limitation: (i) the general economy; (ii) the overall market as well as local, regional or global political and/or social instability; (iii) regulation, taxation or international tax treaties between various countries; or (iv) currency, interest rate or price fluctuations. The Fund’s prospectus provides details of the risks to which the Fund is subject.

Concentration 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.

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 shares sold in the table above.

On August 17, 2018, the SEC adopted amendments to certain disclosure requirements in Securities Act Release No. 33-10532, Disclosure Update and Simplification. The Fund has adopted the amendments pertinent to Regulation S-X in this shareholder report. The amendments impacted certain disclosure presentation on the statement of assets and liabilities, statement of changes in net assets and notes to the financial statements.

Prior year distribution information in the statement of changes in net assets has been modified to conform to the current year presentation in accordance with the Regulation S-X changes.

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 additional disclosure in the financial statements.

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of iShares Interest Rate Hedged Long-Term Corporate Bond ETF (one of the funds constituting iShares U.S. ETF Trust, referred to hereafter as the “Fund”) as of October 31, 2018, the related statement of operations for the year ended October 31, 2018, the statement of changes in net assets for each of the two years in the period ended October 31, 2018, including the related notes, and the financial highlights for each of the three years in the period ended October 31, 2018 and for the period July 22, 2015 (commencement of operations) through October 31, 2015 (hereafter referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of October 31, 2018, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended October 31, 2018 and the financial highlights for each of the three years in the period ended October 31, 2018 and for the period July 22, 2015 (commencement of operations) through October 31, 2015 in conformity with accounting principles generally accepted in the United States of America.

These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of October 31, 2018 by correspondence with the custodian, transfer agent and brokers. We believe that our audits provide a reasonable basis for our opinion.

We have served as the auditor of one or more BlackRock investment companies since 2000.

For the fiscal year ended October 31, 2018, the Fund hereby designates the following 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. At a meeting on May 11, 2018, a committee composed of all of the Independent Trustees (the “15(c) Committee”), with independent counsel, met with management and reviewed and discussed information provided in response to initial requests of the 15(c) Committee and/or their independent counsel, and requested certain additional information, which management agreed to provide. 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 24, 2018, management presented additional information to the Board relating to the continuance of the Advisory Contract, including information requested by the 15(c) Committee during its initial meeting. 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 12-14, 2018, 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. 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 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 various factors, including: (i) the expenses and performance of the Fund; (ii) the nature, extent and quality of the services provided by BFA; (iii) the costs of services provided to the Fund and profits realized by BFA and its affiliates; (iv) economies of scale; (v) the fees and services provided for other comparable funds/accounts managed by BFA and its affiliates; and (vi) other benefits to BFA and/or its affiliates. The material factors, no one of which was controlling, and conclusions that formed the basis for the Board, including the Independent Trustees, to approve the Advisory Contract are discussed below.

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.

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 quarter ended December 31, 2017, to that of relevant comparison fund(s) 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 reference benchmark. Such periodic comparative performance information, including additional detailed information as requested by the Board, was also considered. The Board noted that the Fund generally performed in line with expectations relative to the Fund’s reference benchmark.

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, technology, portfolio management, product design and quality, compliance and risk management, global public policy 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 support 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 relevant officers and other employees of BFA (and its affiliates) 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 12-14, 2018 meeting and throughout the year, and matters related to BFA’s portfolio compliance policies and procedures.

Costs of Services Provided to Fund and Profits Realized by BFA and its Affiliates: The Board reviewed information about the profitability to BlackRock in managing the Fund, based on the fees payable to BFA and its affiliates (including fees under the Advisory Contract), and 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 and the Board had focused on the methodology and profitability presentation during their meetings. The Board further noted that it considered the supplemental information the 15(c) Committee requested, which BlackRock provided, regarding the methodology. The Board discussed the sources of direct and ancillary revenue with management, including the revenues to BTC, a BlackRock affiliate, 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 and other information 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 (collectively, 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 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 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 ETF, as compared to the Other Accounts, particularly those that are institutional clients, in light of differing regulatory requirements and client-imposed mandates. The Board also acknowledged management’s assertion that, for certain iShares funds, and for client segmentation purposes, BlackRock has launched an iShares fund that may provide a similar investment exposure at a lower investment advisory fee rate. The Board also considered the “all-inclusive” nature of the Fund’s advisory fee structure, and the Fund’s 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 (or its 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 also noted the revenue received by BFA and/or its affiliates pursuant to an agreement that permits a service provider to use certain portions of BlackRock’s technology platform to service accounts managed by BFA and/or its affiliates, including the iShares funds. 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 (including associated commissions) 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 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.

Conclusion: Based on a review of the factors described above, as well as such other factors as deemed appropriate by the Board, the Board, including all of the Independent Trustees, determined that the 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 to approve the continuance of the Advisory Contract for the coming year.

Premium/discount information for the Fund covering the most recently completed calendar year and the most recently completed calendar quarters since that year (or since the Fund began trading, if shorter) is publicly accessible, free of charge, at www.iShares.com.

The following information shows the frequency of distributions of premiums and discounts for the Fund for the immediately preceding five calendar years (or from the date the Fund began trading on the secondary market, if less than five years) through the date of the most recent calendar quarter-end. Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. Premium/discount ranges with no trading days are omitted. 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 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 all of the funds within the Exchange-Traded Fund Complex, which consists of 343 funds as of October 31, 2018. With the exception of Robert S. Kapito, Mark K. Wiedman, Charles Park, Martin Small and Benjamin Archibald, the address of each Trustee and officer is c/o BlackRock, Inc., 400 Howard Street, San Francisco, CA 94105. The address of Mr. Kapito, Mr. Wiedman, Mr. Park, Mr. Small and Mr. Archibald is c/o BlackRock, Inc., Park Avenue Plaza, 55 East 52^nd Street, New York, NY 10055. The Board has designated Cecilia H. Herbert as its Independent Board Chair.

All or a portion of this security was purchased with cash collateral received from loaned securities.

Investments in issuers considered to be affiliates of the Fund during the year ended February 28, 2018, for purposes of Section 2(a)(3) of the 1940 Act were as follows:

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.

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.

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 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.

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 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.

transparency of the financial instruments and are not necessarily an indication of the risks associated with investing in those securities.

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.

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 an approved 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.

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 28, 2018, 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. Any non-cash collateral received cannot be sold, re-invested or pledged by the Fund, except in the event of borrower default. 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 28, 2018 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, Inc. (“BlackRock”). BlackRock’s indemnity allows for full replacement of securities loaned if the collateral received does not cover the value of the securities loaned in the event of borrower default. The Fund could incur a loss if the value of an investment purchased with cash collateral falls below the value of the loaned securities or if the value of an investment purchased with cash collateral falls below the value of the original 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 28, 2018:

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 (i) interest and taxes; (ii) brokerage commissions and other expenses connected with the execution of portfolio transactions; (iii) distribution fees; (iv) the advisory fee payable to BFA; and (v) litigation expenses and any extraordinary expenses (in each case as determined by a majority of the independent trustees).

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

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 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 (excluding collateral investment fees), net of fees and other payments to and from borrowers of securities.

movements. A fund is exposed to market risk by its investment in equity, fixed income and/or financial derivative instruments or by 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 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. Securities with longer durations tend to be more sensitive to interest rate changes, usually making their prices more volatile than those of securities with shorter durations. Given the environment of historically low interest rates, a fund may be subject to a greater risk of price losses if interest rates rise.

As of February 28, 2018, the cost of investments (including short positions and derivatives, if any) for federal income tax purposes was $802,605,275. Net unrealized depreciation was $13,545,783, of which $7,184,501 represented gross unrealized appreciation on securities and 20,730,284 represented gross unrealized depreciation on securities.

Management has analyzed tax laws and regulations and their application to the Fund as of February 28, 2018, 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.

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of iShares 10+ Year Credit Bond ETF (one of the funds constituting iShares Trust, referred to hereafter as the “Fund”) as of February 28, 2018, the related statement of operations for the year ended February 28, 2018, the statement of changes in net assets for each of the two years in the period ended February 28, 2018, including the related notes, and the financial highlights for each of the five years in the period ended February 28, 2018 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of February 28, 2018, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended February 28, 2018 and the financial highlights for each of the five years in the period ended February 28, 2018 in conformity with accounting principles generally accepted in the United States of America.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of February 28, 2018 by correspondence with the custodian, transfer agent and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

We have served as the auditor of one or more BlackRock investment companies since 2000.

Global investment-grade bonds declined for the 12 months ended October 31, 2018 (“reporting period”). The Bloomberg Barclays Global Aggregate Index, a broad measure of global bond market performance, returned -2.05% in U.S. dollar terms for the reporting period.

The negative return for global bonds was driven primarily by rising global interest rates and mixed economic data. After a strong 2017, global economic growth eased in 2018 as areas of weakness appeared in several regions of the world. In addition, the global fixed-income markets were affected by a number of external developments, including escalating trade tensions between the U.S. and several of its trading partners (most notably China and Europe), as well as geopolitical conflicts in Turkey and the Middle East.

Regionally, the U.S. bond market declined as a strengthening U.S. economy led to higher interest rates. Driven in part by the stimulative effect of federal tax reform legislation, the U.S. economy grew by 3% for the 12 months ended September 2018, its highest year-over-year growth rate in more than three years. Faster economic growth drove the inflation rate to its highest level in more than six years in mid-2018. In this environment, the U.S. Federal Reserve Bank (“Fed”) increased short-term interest rates four times during the reporting period, increasing its short-term interest rate target to 2.25%, the highest level in more than a decade. From a sector perspective, corporate bonds declined the most amid investor concerns about high corporate debt levels, a decline in average credit quality, and relatively high valuations. In contrast, asset-backed securities (bonds backed by credit card receivables, auto loans, and other debt) advanced for the reporting period, benefiting from their higher yields and relatively short maturities.

The smaller decline in European bond markets was driven in part by a slowdown in economic activity. After improving notably in 2017, economic growth in the Eurozone slowed markedly through the first three quarters of 2018. In particular, growth in the Italian economy slowed significantly following a debt-heavy budget proposed by Italy’s new populist government, which led to a sharp increase in the country’s bond yields late in the reporting period. Other major Eurozone economies, such as Germany and France, also weakened, but to a lesser extent. Despite the economic slowdown, the European Central Bank (“ECB”) reaffirmed its plan to end its quantitative easing measures by the end of 2018, though the ECB intends to maintain its zero interest-rate policy. In the U.K., slowing economic growth and concerns about the economic impact of Brexit when it takes effect in early 2019 kept bond yields relatively stable, leading to positive returns for British bonds.

Asia-Pacific bond markets also declined modestly for the reporting period as economic growth in the region slowed. In Japan, the nation’s longest period of sustained expansion in more than 20 years came to an end when the Japanese economy contracted in the first quarter of 2018. Japanese bond yields increased slightly during the reporting period but remained near historically low levels. In South Korea, bond yields declined as the nation’s economy grew at its slowest pace in nine years. In contrast, Australian bond yields increased as the country’s economy grew at its fastest rate in six years, benefiting from strong consumer spending and increasing commodities prices.

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.

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^® Global Core Index plus interest rate swaps that intend to hedge the interest rate exposure of the J.P. Morgan EMBI^® Global Core Index.

The Fund posted a negative return for the reporting period, as rising U.S. interest rates and a strengthening U.S. dollar weighed on emerging market bond prices. In terms of the Fund’s underlying securities, debt issued by Venezuela, where an ongoing financial crisis led to a significant economic contraction, was the largest detractor to the Fund’s performance. Hyperinflation and insufficient inflows of foreign currency drove Venezuela to default on some of its U.S. dollar-denominated debt. Similarly, Argentina’s debt was negatively affected by the declining Argentine peso, which lowered investors’ confidence in the government’s ability to service its foreign-currency-denominated bonds.

Turkish bonds were significant detractors from the Fund’s performance. High inflation, the depreciation of the Turkish lira, and large trade deficits put pressure on Turkey’s relatively low reserves of foreign currency. Mexican bonds, which have a particularly high rate of foreign ownership, were adversely affected by the depreciation of the Mexican peso and the cancellation of a bond-financed airport project. High foreign ownership also worked against Indonesian debt as foreign investors shifted capital out of Indonesia in search of higher yields.

In that environment, the interest rate hedge was the largest contributor to the Fund’s return. Increasing interest rates reduce the value of existing bonds, meaning a rise in interest rates typically detracts from bond fund performance. Conversely, falling interest rates usually serve to increase bond prices. An interest rate hedged fund attempts to avoid these fluctuations by offsetting interest rate risk, primarily using interest rate swaps and Treasury futures contracts. Rising interest rates during the reporting period meant positive returns from hedging activity.

The Fund’s interest rate hedge seeks near-zero interest rate sensitivity. Consequently, the Fund’s return was minimally affected by interest rate fluctuations during the reporting period. With interest rate sensitivity hedged, the Fund fluctuated based on direct exposure to the yield premium of emerging market bonds, independent of rising interest rates.
