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 mostrecent month-end is available at www.ishares.com. Performance results assume reinvestment of all dividends and capital gain distributions and do not reflect the deductionof 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 withchanges 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 mayreflect 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 calculatemarket 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 fundare 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 theperiod 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 doesnot incur the expenses incurred by a fund. These expenses negatively impact fund performance. Also, market returns do not include brokerage commissions that may bepayable on secondary market transactions. If brokerage commissions were included, market returns would be lower.

Shareholder Expenses

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) ongoingcosts, 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 (orfrom 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 andcents) 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 feewaivers, 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 valuedivided 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 yourFund’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 yourFund 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 commissionspaid 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 relativetotal costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

2. SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies are consistently followed by each Fund in the preparation of its financial statements in conformity with accounting principlesgenerally accepted in the United States of America (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to makecertain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financialstatements 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 aredetermined using the specific identification method. Interest income, including amortization and accretion of premiums and discounts on debt securities, andpayment-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-dividenddate, net of any foreign taxes withheld at source.

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 netrealized 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 netinvestment income and net realized capital gains for financial reporting purposes. Dividends and distributions are paid in U.S. dollars and cannot be automatically reinvestedin additional shares of the Funds.

Recent Accounting Standards: In March 2017, the Financial Accounting Standards Board issued Accounting Standards Update “Premium Amortization on PurchaseCallable Debt Securities” which amends the amortization period for certain purchased callable debt securities. Under the new guidance, premium amortization of purchasedcallable 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 appliedon a modified retrospective basis and is effective for fiscal years, and their interim periods, beginning after December 15, 2018. Management continues to evaluate theimpact 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. TheFunds' maximum exposure under these arrangements is unknown because it involves future potential claims against the Funds, which cannot be predicted with anycertainty.

3. INVESTMENT VALUATION AND FAIR VALUE MEASUREMENTS

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 theFund’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 notopen. 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 atthe measurement date. A fund determines the fair value of its financial instruments using various independent dealers or pricing services under policies approved by theBoard of Trustees of the Trust (the “Board”). The BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) is the committee formed bymanagement 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:• Fixed-income investments are valued using the last available bid price or current market quotations provided by independent dealers or prices (including evaluated

prices) supplied by approved independent third-party pricing services. Pricing services generally value fixed income securities assuming orderly transactions of aninstitutional round lot size, but a fund may hold or transact in such securities in smaller, odd lot sizes. Odd lots may trade at lower prices than institutional round lots.The pricing services may use matrix pricing or valuation models that utilize certain inputs and assumptions to derive values, including transaction data, credit qualityinformation, perceived market movements, news, and other relevant information and by other methods, which may include consideration of: yields or prices ofsecurities of comparable quality, coupon, maturity and type; indications as to values from dealers; general market conditions; and/or other factors and assumptions.

• Exchange-traded funds and closed-end funds traded on a recognized securities exchange are valued at that day’s last traded price or official closing price, asapplicable, on the exchange where the fund is primarily traded. Funds traded on a recognized exchange for which there were no sales on that day may be valued atthe last traded price.

• Investments in open-end U.S. mutual funds (including money market funds) are valued at that day’s published net asset value (“NAV”).

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 thatapplication 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 priceis 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 ValuedInvestments”). 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 principalmarket for the investment; (iii) the customary participants in the principal market for the investment; (iv) data assumptions by market participants for the investment, ifreasonably 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 resultin a difference between the fund’s performance and the performance of the fund’s underlying index.

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 valuehierarchy consisting of three broad levels for financial reporting purposes as follows:

• Level 1 – Unadjusted price quotations in active markets for identical assets or liabilities;• Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly, including, but not limited to,

quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not considered tobe active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, yield curves, volatilities, prepayment speeds, lossseverities, credit risks and default rates) or other market-corroborated inputs; and

• Level 3 – Unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available, (including the GlobalValuation Committee’s assumptions used in determining the fair value of financial instruments).

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 tounobservable 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 classificationis 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 includedin its schedule of investments. The categorization of a value determined for financial instruments is based on the pricing transparency of the financial instruments and is notnecessarily an indication of the risks associated with investing in those securities.

4. SECURITIES AND OTHER INVESTMENTS

Securities Lending: Each Fund may lend its securities to approved borrowers, such as brokers, dealers and other financial institutions. The borrower pledges andmaintains 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 securitieson 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 Fundor 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 loanedsecurities 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 requiredto return borrowed securities within the standard time period for settlement of securities transactions.

As of April 30, 2019, any securities on loan were collateralized by cash and/or U.S. government obligations. Cash collateral received was invested in money market fundsmanaged by BlackRock Fund Advisors (“BFA”), the Funds' investment adviser, or its affiliates and is disclosed in the schedules of investments. Any non-cash collateralreceived 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 itsschedule of investments. The market value of any securities on loan as of April 30, 2019 and the value of the related cash collateral are disclosed in the statements of assetsand 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 valueof 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, bankruptcyor 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 orinsolvency. 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 inconnection with loaned securities.

(a) Collateral received in excess of the market value of securities on loan is not presented in this table. The total cash collateral received by each Fund is disclosed in the Fund's statementof assets and liabilities.

(b) Additional collateral is delivered to the Fund on the next business day in accordance with the MSLA. The net amount would be subject to the borrower default indemnity in the eventof default by a counterparty.

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 mitigatethese risks, each Fund benefits from a borrower default indemnity provided by BlackRock, Inc. (“BlackRock”). BlackRock’s indemnity allows for full replacement of thesecurities 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 aninvestment 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 belowthe value of the original cash collateral received. Such losses are borne entirely by each Fund.

5. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Investment Advisory Fees: Pursuant to an Investment Advisory Agreement with the Trust, BFA manages the investment of each Fund’s assets. BFA is a Californiacorporation indirectly owned by BlackRock. Under the InvestmentAdvisoryAgreement, BFA is responsible for substantially all expenses of the Funds, except (i) interest andtaxes; (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 Fund, BFA is entitled to an annual investment advisory fee of 0.10%, accrued daily and paid monthly by the Funds, based onthe average daily net assets of each 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 andexpenses”). BFA has contractually agreed to waive a portion of its investment advisory fee for each Fund through the termination date of such Fund, in an amount equalto acquired fund fees and expenses, if any, attributable to each Fund’s investments in other funds advised by BFA or its affiliates.

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 orexpenses 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 operationalcosts 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 moneymarket 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 collateralinvestment 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 thereinvestment of cash collateral (excluding collateral investment fees), net of fees and other payments to and from borrowers of securities. Each Fund retains a portion ofsecurities lending income and remits the remaining portion to BTC as compensation for its services as securities lending agent.

Pursuant to the current securities lending agreement, each Fund retains 82% of securities lending income (which excludes collateral investment fees) and the amountretained can never be less than 70% of the total of securities lending income plus the collateral investment fees. Prior to January 1, 2019, the Fund retained 80% of securitieslending income (which excludes collateral investment fees) and the amount retained was not less than 70% of the total of securities lending income plus the collateralinvestment 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 ActiShares exchange-traded funds (the “iShares ETF Complex”) in a given calendar year exceeds a specified threshold, each Fund, pursuant to the securities lendingagreement, 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 securitieslending income plus the collateral investment fees. Prior to January 1, 2019, the Fund was subject to the same terms under the previous securities lending fee arrangement.

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 six months endedApril 30, 2019, the Funds paid BTC the following amounts for securities lending agent services:

7. INCOME TAX INFORMATION

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 investmentcompany by complying with the provisions applicable to regulated investment companies, as defined under Subchapter M of the Internal Revenue Code of 1986, asamended, and to annually distribute substantially all of its ordinary income and any net capital gains (taking into account any capital loss carryforwards) sufficient to relieveit 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 April 30, 2019, inclusive of the open tax return years, and does not believe thatthere are any uncertain tax positions that require recognition of a tax liability in the Funds' financial statements.

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

8. PRINCIPAL RISKS

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 variousrisks, 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 mayalso 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 socialinstability; (iii) regulation, taxation or international tax treaties between various countries; or (iv) currency, interest rate or price fluctuations. Each Fund’s prospectus providesdetails of the risks to which the Fund is subject.

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 wellas 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 compositionof the portfolio is monitored by BFA.

Market Risk: Market risk arises mainly from uncertainty about future values of financial instruments influenced by price, currency and interest rate movements. It representsthe 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, fixedincome 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 marketconditions, economic trends or events that are not specifically related to the issuers of the securities including local, regional or global political, social or economic instabilityor 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 inthe fund’s 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 arenot 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 ofwithholding 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 forinvestments 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 bondsand 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 interestrate 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 besubject 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, repurchaseagreements or loans of portfolio securities, is unable or unwilling to make timely interest and/or principal payments or to otherwise honor its obligations.

manage counterparty credit risk by entering into transactions only with counterparties that they believe have the financial resources to honor their obligations and bymonitoring the financial stability of those counterparties. Financial assets, which potentially expose a fund to issuer and counterparty credit risks, consist principally offinancial instruments and receivables due from counterparties. The extent of a fund’s exposure to credit and counterparty risks with respect to those financial assets isapproximated by their value recorded in its statement of assets and liabilities.

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 particularinvestment 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 specifiedamount 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 Unitsmay 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 othertransaction costs associated with the issuance and redemption of Creation Units, including Creation Units for cash. Investors transacting in Creation Units for cash may alsopay an additional variable charge to compensate the relevant fund for certain transaction costs (i.e., stamp taxes, taxes on currency or other financial transactions, andbrokerage 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.

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 transactionsare reflected as a receivable or a payable in the statement of assets and liabilities.

10. LEGAL PROCEEDINGS

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 RussellMid-Cap Growth ETF, iShares Russell Mid-Cap ETF, iShares Russell Mid-Cap Value ETF, iShares Select Dividend ETF, iShares Morningstar Mid-Cap ETF, iSharesMorningstar Large-Cap ETF, iShares U.S. Aerospace & Defense ETF and iShares Preferred and Income Securities 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 lawsuitalleges 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-lossorders 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 thePlaintiffs lack standing to assert their claims. On October 11, 2017, the court entered final judgment dismissing all of the Plaintiffs’ claims with prejudice. Plaintiffs haveappealed the court’s decision.

11. SUBSEQUENT EVENTS

(a) The Fund estimates that it has distributed more than the amount of earned income and net realized gains; therefore, a portion of the distribution may be a return of capital. A returnof capital may occur, for example, when some or all of the shareholder's investment in the Fund is returned to the shareholder. A return of capital does not necessarily reflect theFund's investment performance and should not be confused with "yield" or "income". When distributions exceed total return performance, the difference will incrementally reduce theFund's net asset value per share.
