Derivative Financial Instruments The Master Portfolio may invest in various derivative financial instruments.

The use of these instruments may result in losses greater than if they had not been used, may limit the amount of appreciation the Master Portfolio can realize on an investment and/or may result in lower distributions paid to shareholders.

1. ORGANIZATION

Master Investment Portfolio (“MIP”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end management investmentcompany. MIP is organized as a Delaware statutory trust. Active Stock Master Portfolio (the “Master Portfolio”) is a series of MIP. The Master Portfolio is classified asdiversified.

The Master Portfolio, together with certain other registered investment companies advised by BlackRock Fund Advisors (the “Manager”) or its affiliates, is included in acomplex of equity, multi-asset, index and money market funds referred to as the BlackRock Multi-Asset Complex.

2. SIGNIFICANT ACCOUNTING POLICIES

The financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which may requiremanagement to make estimates and assumptions that affect the reported amounts of assets and liabilities in the financial statements, disclosure of contingent assets andliabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actualresults could differ from those estimates. The Master Portfolio is considered an investment company under U.S. GAAP and follows the accounting and reporting guidanceapplicable to investment companies. Below is a summary of significant accounting policies:

Investment Transactions and Income Recognition: For financial reporting purposes, investment transactions are recorded on the dates the transactions are executed(the “trade dates”). Realized gains and losses on investment transactions are determined on the identified cost basis. Dividend income is recorded on the ex-dividend date.Dividends from foreign securities where the ex-dividend date may have passed are subsequently recorded when the Master Portfolio is informed of the ex-dividend date.Under the applicable foreign tax laws, a withholding tax at various rates may be imposed on capital gains, dividends and interest. Upon notification from issuers, a portionof the dividend income received from a real estate investment trust may be redesignated as a reduction of cost of the related investment and/or realized gain. Interestincome, including amortization and accretion of premiums and discounts on debt securities is recognized on an accrual basis.

Foreign Currency Translation: The Master Portfolio’s books and records are maintained in U.S. dollars. Securities and other assets and liabilities denominated in foreigncurrencies are translated into U.S. dollars using exchange rates determined as of the close of trading on the New York Stock Exchange (“NYSE”). Purchases and sales ofinvestments are recorded at the rates of exchange prevailing on the respective dates of such transactions. Generally, when the U.S. dollar rises in value against a foreigncurrency, the investments denominated in that currency will lose value; the opposite effect occurs if the U.S. dollar falls in relative value.

The Master Portfolio does not isolate the portion of the results of operations arising as a result of changes in the exchange rates from the changes in the market prices ofinvestments held or sold for financial reporting purposes. Accordingly, the effects of changes in exchange rates on investments are not segregated in the Statement ofOperations from the effects of changes in market prices of those investments, but are included as a component of net realized and unrealized gain (loss) from investments.The Master Portfolio reports realized currency gains (losses) on foreign currency related transactions as components of net realized gain (loss) for financial reportingpurposes, whereas such components are generally treated as ordinary income for U.S. federal income tax purposes.

Segregation and Collateralization: In cases where the Master Portfolio enters into certain investments (e.g., futures contracts) that would be treated as “seniorsecurities” for 1940 Act purposes, the Master Portfolio may segregate or designate on its books and records cash or liquid assets having a market value at least equal tothe amount of its future obligations under such investments. Doing so allows the investment to be excluded from treatment as a “senior security.” Furthermore, if requiredby an exchange or counterparty agreement, the Master Portfolio may be required to deliver/deposit cash and/or securities to/with an exchange, or broker-dealer orcustodian as collateral for certain investments or obligations.

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

Other: Expenses directly related to the Master Portfolio are charged to the Master Portfolio. Other operating expenses shared by several funds, including other fundsmanaged by the Manager, are prorated among those funds on the basis of relative net assets or other appropriate methods.

3. INVESTMENT VALUATION AND FAIR VALUE MEASUREMENTS

Investment Valuation Policies: The Master Portfolio’s investments are valued at fair value (also referred to as “market value” within the financial statements) as of theclose of trading on the NYSE (generally 4:00 p.m., Eastern time) (or if the reporting date falls on a day the NYSE is closed, investments are valued at fair value as of theperiod end). U.S. GAAP defines fair value as the price the Master Portfolio would receive to sell an asset or pay to transfer a liability in an orderly transaction betweenmarket participants at the measurement date. The Master Portfolio determines the fair values of its financial instruments using various independent dealers or pricingservices under policies approved by the Board of Trustees of MIP (the “Board”). The BlackRock Global Valuation Methodologies Committee (the “Global ValuationCommittee”) 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 Master Portfolio’s assets and liabilities:

• Equity investments traded on a recognized securities exchange are valued at the official closing price each day, if available. For equity investments traded on morethan one exchange, the official closing price on the exchange where the stock is primarily traded is used. Equity investments traded on a recognized exchange forwhich there were no sales on that day may be valued at the last available bid (long positions) or ask (short positions) price.

Generally, trading in foreign instruments is substantially completed each day at various times prior to the close of trading on the NYSE. Occasionally, eventsaffecting the values of such instruments may occur between the foreign market close and the close of trading on the NYSE that may not be reflected in the

Page 24: Portfolio Information - BlackRock€¦ · For Active Stock Master Portfolio (the “Master Portfolio”) compliance purposes, the Master Portfolio’s sector classifications refer

Notes to Financial Statements (unaudited) (continued)

computation of the Master Portfolio’s net assets. Each business day, the Master Portfolio uses a pricing service to assist with the valuation of certain foreignexchange-traded equity securities and foreign exchange-traded and over-the-counter (“OTC”) options (the “Systematic Fair Value Price”). Using current marketfactors, the Systematic Fair Value Price is designed to value such foreign securities and foreign options at fair value as of the close of trading on the NYSE, whichfollows the close of the local markets.

• Investments in open-end U.S. mutual funds are valued at net asset value (“NAV”) each business day.

• Futures contracts traded on exchanges are valued at their last sale price.

If events (e.g., a company announcement, market volatility or a natural disaster) occur that are expected to materially affect the value of such investments, or in the eventthat the 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 aprice is not available, the investment will be valued by the Global Valuation Committee, or its delegate, in accordance with a policy approved by the Board as reflecting fairvalue (“Fair Valued Investments”). The fair valuation approaches that may be used by the Global Valuation Committee will include market approach, income approach andcost approach. Valuation techniques such as discounted cash flow, use of market comparables and matrix pricing are types of valuation approaches and are typically usedin determining fair value. When determining the price for Fair Valued Investments, the Global Valuation Committee, or its delegate, seeks to determine the price that theMaster Portfolio might reasonably expect to receive or pay from the current sale or purchase of that asset or liability in an arm’s-length transaction. Fair valuedeterminations shall be based upon all available factors that the Global Valuation Committee, or its delegate, deems relevant and consistent with the principles of fair valuemeasurement. The pricing of all Fair Valued Investments is subsequently reported to the Board or a committee thereof on a quarterly basis.

Fair Value Hierarchy: Various inputs are used in determining the fair value of investments and derivative financial instruments. These inputs to valuation techniques arecategorized into a fair value hierarchy consisting of three broad levels for financial statement purposes as follows:

• Level 1 — Unadjusted price quotations in active markets/exchanges for identical assets or liabilities that the Master Portfolio has the ability to access

• Level 2 — Other observable inputs (including, but not limited to, quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical orsimilar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yieldcurves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market–corroborated inputs)

• Level 3 — Unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available (including the MasterPortfolio’s own assumptions used in determining the fair value of investments and derivative 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 judgment 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. Investments classified within Level 3 have significantunobservable inputs used by the Global Valuation Committee in determining the price for Fair Valued Investments. Level 3 investments include equity or debt issued byprivately held companies or funds. There may not be a secondary market, and/or there are a limited number of investors. The categorization of a value determined forinvestments and derivative financial instruments is based on the pricing transparency of the investments and derivative financial instruments and is not necessarily anindication of the risks associated with investing in those securities.

4. SECURITIES AND OTHER INVESTMENTS

Preferred Stocks: Preferred stock has a preference over common stock in liquidation (and generally in receiving dividends as well), but is subordinated to the liabilities ofthe issuer in all respects. As a general rule, the market value of preferred stock with a fixed dividend rate and no conversion element varies inversely with interest ratesand perceived credit risk, while the market price of convertible preferred stock generally also reflects some element of conversion value. Because preferred stock is juniorto debt securities and other obligations of the issuer, deterioration in the credit quality of the issuer will cause greater changes in the value of a preferred stock than in amore senior debt security with similar stated yield characteristics. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by theissuer’s board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions.

Securities Lending: The Master Portfolio may lend its securities to approved borrowers, such as brokers, dealers and other financial institutions. The borrower pledgesand maintains with the Master Portfolio collateral consisting of cash, an irrevocable letter of credit issued by a bank, or securities issued or guaranteed by the U.S.Government. The initial collateral received by the Master Portfolio is required to have a value of at least 102% of the current value of the loaned securities for securitiestraded 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 currentmarket value of the securities on loan. The market value of the loaned securities is determined at the close of each business day of the Master Portfolio and any additionalrequired collateral is delivered to the Master Portfolio, or excess collateral returned by the Master Portfolio, on the next business day. During the term of the loan, theMaster Portfolio 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. Loansof 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 securitiestransactions.

The market value of any securities on loan, all of which were classified as common stocks in the Master Portfolio’s Schedule of Investments, and the value of any relatedcollateral are shown separately in the Statement of Assets and Liabilities as a component of investments at value-unaffiliated, and collateral on securities loaned at value,respectively. As of period end, any securities on loan were collateralized by cash and/or U.S. Government obligations. Cash collateral invested by the securities lendingagent, BlackRock Institutional Trust Company, N.A. (“BTC”), if any, is disclosed in the Schedule of Investments.

Securities lending transactions are entered into by the Master Portfolio under Master Securities Lending Agreements (each, an “MSLA”), which provide the right, in theevent 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 Master Portfolio, as lender, would offset the market value of the collateral received against the market valueof the securities loaned. When the value of the collateral is greater than that of the market value of the securities loaned, the lender is left with a net amount payable to thedefaulting 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 ofan 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 MasterPortfolio can reinvest cash collateral received in connection with loaned securities. Upon an event of default, the parties’ obligations to return the securities or collateral tothe other party are extinguished, and the parties can resell or re-pledge the loaned securities or the collateral received in connection with the loaned securities in order tosatisfy the defaulting party’s net payment obligation for all transactions under the MSLA. The defaulting party remains liable for any deficiency.

As of period end, the following table is a summary of the Master Portfolio’s securities lending agreements by counterparty which are subject to offset under an MSLA:

(a) Cash collateral with a value of $33,172,979 has been received in connection with securities lending agreements. Collateral received in excess of the value of securities loaned fromthe individual counterparty, if any, is not shown for financial reporting purposes in the table above.

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, the Master Portfolio benefits from a borrower default indemnity provided by BlackRock, Inc. (“BlackRock”). BlackRock’s indemnity allows for full replacement ofthe securities loaned to the extent the collateral received does not cover the value on the securities loaned in the event of borrower default. The Master Portfolio couldincur a loss if the value of an investment purchased with cash collateral falls below the market value of loaned securities or if the value of an investment purchased withcash collateral falls below the value of the original cash collateral received. Such losses are borne entirely by the Master Portfolio.

5. DERIVATIVE FINANCIAL INSTRUMENTS

The Master Portfolio engages in various portfolio investment strategies using derivative contracts both to increase the returns of the Master Portfolio and/or to manage itsexposure to certain risks such as credit risk, equity risk, interest rate risk, foreign currency exchange rate risk, commodity price risk or other risks (e.g., inflation risk).Derivative financial instruments categorized by risk exposure are included in the Schedule of Investments. These contracts may be transacted on an exchange or OTC.

Futures Contracts: Futures contracts are purchased or sold to gain exposure to, or manage exposure to, changes in interest rates (interest rate risk), and changes in thevalue of equity securities (equity risk) or foreign currencies (foreign currency exchange rate risk).

Futures contracts are agreements between the Master Portfolio and a counterparty to buy or sell a specific quantity of an underlying instrument at a specified price and ona specified date. Depending on the terms of a contract, it is settled either through physical delivery of the underlying instrument on the settlement date or by payment of acash amount on the settlement date. Upon entering into a futures contract, the Master Portfolio is required to deposit initial margin with the broker in the form of cash orsecurities in an amount that varies depending on a contract’s size and risk profile. The initial margin deposit must then be maintained at an established level over the life ofthe contract. Amounts pledged, which are considered restricted, are included in cash pledged for futures contracts in the Statement of Assets and Liabilities.

Securities deposited as initial margin are designated in the Schedule of Investments and cash deposited, if any, is shown as cash pledged for futures contracts in theStatement of Assets and Liabilities. Pursuant to the contract, the Master Portfolio agrees to receive from or pay to the broker an amount of cash equal to the dailyfluctuation in market value of the contract (“variation margin”). Variation margin is recorded as unrealized appreciation (depreciation) and, if any, shown as variation marginreceivable (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 ofOperations 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. The use offutures contracts involves the risk of an imperfect correlation in the movements in the price of futures contracts and interest, foreign currency exchange rates or underlyingassets.

6. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Investment Advisory: MIP, on behalf of the Master Portfolio, entered into an Investment Advisory Agreement with the Manager, the Master Portfolio’s investment adviserand an indirect, wholly-owned subsidiary of BlackRock, to provide investment advisory services. The Manager is responsible for the management of the Master Portfolio’sportfolio and provides the personnel, facilities, equipment and certain other services necessary to the operations of the Master Portfolio.

For such services, the Master Portfolio pays the Manager a monthly fee at an annual rate equal to the following percentages of the average daily value of the MasterPortfolio’s net assets.

Administration: MIP, on behalf of the Master Portfolio, entered into an Administration Agreement with BlackRock Advisors, LLC (“BAL” or the “Administrator”), which hasagreed to provide general administrative services (other than investment advice and related portfolio activities). BAL, has agreed to bear all of the Master Portfolio’sordinary operating expenses, excluding, generally, investment advisory fees, distribution fees, brokerage and other expenses related to the execution of portfoliotransactions, extraordinary expenses and certain other expenses which are borne by the Master Portfolio. BAL is entitled to receive for these administrative services anannual fee of 0.10% based on the average daily net assets of the Master Portfolio.

From time to time, BAL may waive such fees in whole or in part. Any such waiver will reduce the expenses of the Master Portfolio and, accordingly, have a favorableimpact on its performance. BAL may delegate certain of its administration duties to sub-administrators.

Expense Waivers and Reimbursements: The Manager has voluntarily agreed to waive a portion of the investment advisory fees payable by the Master Portfolio. Thisvoluntary waiver may be terminated at any time. This amount is included in fees waived and/or reimbursed by the Manager in the Statement of Operations. For the sixmonths ended June 30, 2019, the Manager waived $214,869 pursuant to this agreement.

BAL voluntarily agreed to waive a portion of its administration fees payable by the Master Portfolio. This arrangement is voluntary and may be terminated by BAL at anytime. This amount is included in fees waived and/or reimbursed by the Administrator in the Statement of Operations. For the six months ended June 30, 2019, the amountwaived was $226,178.

The fees and expenses of MIP’s trustees who are not “interested persons” of MIP, as defined in the 1940 Act (“Independent Trustees”), counsel to the IndependentTrustees and MIP’s independent registered public accounting firm (together, the “independent expenses”) are paid directly by the Master Portfolio. BAL has contractuallyagreed to reimburse the Master Portfolio or provide an offsetting credit against the administration fees paid by the Master Portfolio in an amount equal to the independentexpenses through April 30, 2020. For the six months ended June 30, 2019, the amount waived and/or reimbursed was $20,135.

With respect to the Master Portfolio, the Manager voluntarily agreed to waive its investment advisory fees by the amount of investment advisory fees the Master Portfoliopays to the Manager indirectly through its investment in affiliated money market funds (the “affiliated money market fund waiver”). This amount is included in fees waivedand/or reimbursed by the Manager in the Statement of Operations. For the six months ended June 30, 2019, the amount waived was $12,204.

The Manager has contractually agreed to waive its investment advisory fee with respect to any portion of the Master Portfolio’s assets invested in affiliated equity andfixed-income mutual funds and affiliated exchange-traded funds that have a contractual management fee through April 30, 2020. The contractual agreement may beterminated upon 90 days’ notice by a majority of the Independent Trustees or by a vote of a majority of the outstanding voting securities of the Master Portfolio. For the sixmonths ended June 30, 2019, there were no fees waived by the Manager pursuant to this arrangement.

Securities Lending: The U.S. Securities and Exchange Commission (“SEC”) has issued an exemptive order which permits BTC, an affiliate of the Manager, to serve assecurities lending agent for the Master Portfolio, subject to applicable conditions. As securities lending agent, BTC bears all operational costs directly related to securitieslending. The Master Portfolio is responsible for fees in connection with the investment of cash collateral received for securities on loan (the “collateral investment fees”).The cash collateral is invested in a money market fund managed by the Manager or its affiliates. However, BTC has agreed to reduce the amount of securities lendingincome it receives in order to effectively limit the collateral investment fees the Master Portfolio bears to an annual rate of 0.04%. The shares of such money market fundshares will not be subject to a sales load, distribution fee or service fee. The money market fund in which the cash collateral has been invested may, under certaincircumstances, impose a liquidity fee of up to 2% of the value redeemed or temporarily restrict redemptions for up to 10 business days during a 90 day period, in the eventthat the money market fund’s weekly liquid assets fall below certain thresholds.

Securities lending income is equal to the total of income earned from the reinvestment of cash collateral, net of fees and other payments to and from borrowers ofsecurities, and less the collateral investment fees. The Master Portfolio retains a portion of securities lending income and remits a remaining portion to BTC ascompensation for its services as securities lending agent.

Pursuant to the current securities lending agreement, the Master Portfolio retains 73.5% of securities lending income (which excludes collateral investment fees), and thisamount 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 earned across the BlackRock Multi-Asset Complex in a calendaryear exceeds a specified threshold, the Master Portfolio, pursuant to the securities lending agreement, will retain for the remainder of that calendar year securities lendingincome in an amount equal to 80% of securities lending income (which excludes collateral investment fees), and this amount retained can never be less than 70% of thetotal of securities lending income plus the collateral investment fees.

Notes to Financial Statements (unaudited) (continued)

The share of securities lending income earned by the Master Portfolio is shown as securities lending income — affiliated — net in the Statement of Operations. For the sixmonths ended June 30, 2019, the Master Portfolio paid BTC $18,179 in total for securities lending agent services.

Interfund Lending: In accordance with an exemptive order (the “Order”) from the SEC, the Master Portfolio may participate in a joint lending and borrowing facility fortemporary purposes (the “Interfund Lending Program”), subject to compliance with the terms and conditions of the Order, and to the extent permitted by the MasterPortfolio’s investment policies and restrictions. The Master Portfolio is currently permitted to borrow and lend under the Interfund Lending Program.

A lending BlackRock fund may lend in aggregate up to 15% of its net assets, but may not lend more than 5% of its net assets to any one borrowing fund through theInterfund Lending Program. A borrowing BlackRock fund may not borrow through the Interfund Lending Program or from any other source more than 33 1/3% of its totalassets (or any lower threshold provided for by the fund’s investment restrictions). If a borrowing BlackRock fund’s total outstanding borrowings exceed 10% of its totalassets, each of its outstanding interfund loans will be subject to collateralization of at least 102% of the outstanding principal value of the loan. All interfund loans are fortemporary or emergency purposes and the interest rate to be charged will be the average of the highest current overnight repurchase agreement rate available to a lendingfund and the bank loan rate, as calculated according to a formula established by the Board.

During the six months ended June 30, 2019, the Master Portfolio did not participate in the Interfund Lending Program.

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

7. PURCHASES AND SALES

For the six months ended June 30, 2019, purchases and sales of investments and excluding short-term securities, were $347,995,657 and $371,237,320, respectively.

8. INCOME TAX INFORMATION

The Master Portfolio is classified as a partnership for U.S. federal income tax purposes. As such, each investor in the Master Portfolio is treated as the owner of itsproportionate share of net assets, income, expenses and realized and unrealized gains and losses of the Master Portfolio. Therefore, no U.S. federal income tax provisionis required. It is intended that the Master Portfolio’s assets will be managed so an investor in the Master Portfolio can satisfy the requirements of Subchapter M of theInternal Revenue Code of 1986, as amended.

The Master Portfolio files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on theMaster Portfolio’s U.S. federal tax returns generally remains open for each of the four years ended December 31, 2018. The statutes of limitations on the Master Portfolio’sstate and local tax returns may remain open for an additional year depending upon the jurisdiction.

Management has analyzed tax laws and regulations and their application to the Master Portfolio as of June 30, 2019, inclusive of the open tax return years, and does notbelieve that there are any uncertain tax positions that require recognition of a tax liability in the Master Portfolio’s financial statements.

9. BANK BORROWINGS

MIP, on behalf of the Master Portfolio along with certain other funds managed by the Manager and its affiliates (“Participating Funds”), is a party to a 364-day, $2.25 billioncredit agreement with a group of lenders. Under this agreement, the Master Portfolio may borrow to fund shareholder redemptions. Excluding commitments designated forcertain individual funds, the Participating Funds, including the Master Portfolio, can borrow up to an aggregate commitment amount of $1.75 billion at any time outstanding,subject to asset coverage and other limitations as specified in the agreement. The credit agreement has the following terms: a fee of 0.10% per annum on unusedcommitment amounts and interest at a rate equal to the higher of (a) one-month LIBOR (but, in any event, not less than 0.00%) on the date the loan is made plus 0.80%per annum or (b) the Fed Funds rate (but, in any event, not less than 0.00%) in effect from time to time plus 0.80% per annum on amounts borrowed. The agreementexpires in April 2020 unless extended or renewed. Prior to April 18, 2019, Participating Funds paid an upfront commitment fee of 0.02% on the total commitment amounts,in addition to administration, legal and arrangement fees, which are included in miscellaneous expenses in the Statement of Operations. These fees were allocated amongsuch funds based upon portions of the aggregate commitment available to them and relative net assets of Participating Funds. During the six months ended June 30,2019, the Master Portfolio did not borrow under the credit agreement.

10. PRINCIPAL RISKS

In the normal course of business, the Master Portfolio invests in securities or other instruments and may enter into certain transactions, and such activities subject theMaster Portfolio 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 securitiesor 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 globalpolitical and/or social instability; (iii) regulation, taxation or international tax treaties between various countries; or (iv) currency, interest rate and price fluctuations. TheMaster Portfolio’s prospectus provides details of the risks to which the Master Portfolio is subject.

Notes to Financial Statements (unaudited) (continued)

The Master Portfolio may be exposed to additional risks when reinvesting cash collateral in money market funds that do not seek to maintain a stable NAV per share of$1.00, which may be subject to redemption gates or liquidity fees under certain circumstances.

Valuation Risk: The market values of equities, such as common stocks and preferred securities or equity related investments, such as futures and options, may declinedue to general market conditions which are not specifically related to a particular company. They may also decline due to factors which affect a particular industry orindustries. The Master Portfolio may invest in illiquid investments. An illiquid investment is any investment that the Master Portfolio reasonably expects cannot be sold ordisposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. TheMaster Portfolio may experience difficulty in selling illiquid investments in a timely manner at the price that it believes the investments are worth. Prices may fluctuatewidely over short or extended periods in response to company, market or economic news. Markets also tend to move in cycles, with periods of rising and falling prices.This volatility may cause the Master Portfolio’s NAV to experience significant increases or decreases over short periods of time. If there is a general decline in thesecurities and other markets, the NAV of the Master Portfolio may lose value, regardless of the individual results of the securities and other instruments in which theMaster Portfolio invests.

Counterparty Credit Risk: The Master Portfolio may be exposed to counterparty credit risk, or the risk that an entity may fail to or be unable to perform on itscommitments related to unsettled or open transactions. The Master Portfolio manages counterparty credit risk by entering into transactions only with counterparties thatthe Manager believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, whichpotentially expose the Master Portfolio to market, issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties.The extent of the Master Portfolio’s exposure to market, issuer and counterparty credit risks with respect to these financial assets is approximately their value recorded inthe Statement of Assets and Liabilities, less any collateral held by the Master Portfolio.

A derivative contract may suffer a mark-to-market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlyinginstrument. Losses can also occur if the counterparty does not perform under the contract.

With exchange-traded futures, there is less counterparty credit risk to the Master Portfolio since the exchange or clearinghouse, as counterparty to such instruments,guarantees against a possible default. The clearinghouse stands between the buyer and the seller of the contract; therefore, credit risk is limited to failure of theclearinghouse. While offset rights may exist under applicable law, the Master Portfolio does not have a contractual right of offset against a clearing broker or clearinghousein the event of a default (including the bankruptcy or insolvency). Additionally, credit risk exists in exchange-traded futures with respect to initial and variation margin that isheld in a clearing broker’s customer accounts. While clearing brokers are required to segregate customer margin from their own assets, in the event that a clearing brokerbecomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the clearing broker for all its clients, typically theshortfall would be allocated on a pro rata basis across all the clearing broker’s customers, potentially resulting in losses to the Master Portfolio.

11. SUBSEQUENT EVENTS

Management has evaluated the impact of all subsequent events on the Master Portfolio through the date the financial statements were issued and has determined thatthere were no subsequent events requiring adjustment or additional disclosure in the financial statements.

Disclosure of Investment Advisory Agreement

The Board of Trustees (the “Board,” the members of which are referred to as “Board Members”) of Master Investment Portfolio (the “Master Fund”) met in person onApril 17, 2019 (the “April Meeting”) and May 14-15, 2019 (the “May Meeting”) to consider the approval of the investment advisory agreement (the “Agreement”) betweenthe Master Fund, on behalf of Active Stock Master Portfolio (the “Portfolio”), a series of the Master Fund, and BlackRock Fund Advisors (the “Manager” or “BlackRock”),the Master Fund’s investment advisor.

Activities and Composition of the Board

On the date of the May Meeting, the Board consisted of fifteen individuals, thirteen of whom were not “interested persons” of the Master Fund as defined in the InvestmentCompany Act of 1940, as amended (the “1940 Act”) (the “Independent Board Members”).

The Board has four quarterly meetings peryear, each typically extending for two days, and additional in-person and telephonic meetings throughout the year, as needed. While the Board also has a fifth one-daymeeting to consider specific information surrounding the renewal of the Agreement, the Board’s consideration entails a year-long deliberative process whereby the Boardand its committees assess BlackRock’s services to the Portfolio. In particular, the Board assessed, among other things, the nature, extent and quality of the servicesprovided to the Portfolio by BlackRock, BlackRock’s personnel and affiliates, including (as applicable): investment management; accounting, administrative andshareholder services; oversight of the Portfolio’s service providers; risk management and oversight; legal and compliance services; and ability to meet applicable legal andregulatory requirements. Throughout the year, including during the contract renewal process, the Independent Board Members were advised by independent legal counsel,and met with independent legal counsel in various executive sessions outside of the presence of management.

During the year, the Board, acting directly and through its committees, considers information that is relevant to its annual consideration of the renewal of the Agreement,including the services and support provided by BlackRock to the Portfolio and its shareholders. BlackRock also furnished additional information to the Board in response tospecific questions from the Board. This additional information is discussed further below in the section titled “Board Considerations in Approving the Agreement.” Amongthe matters the Board considered were: (a) investment performance for one-year, three-year, five-year, ten-year, and/or since inception periods, as applicable, againstpeer funds, applicable benchmark, and performance metrics, as applicable, as well as senior management’s and portfolio managers’ analyses of the reasons for any over-performance or under-performance relative to its peers, benchmarks, and other performance metrics, as applicable; (b) fees, including advisory, administration, ifapplicable, and other amounts paid to BlackRock and its affiliates by the Portfolio for services; (c) Portfolio operating expenses and how BlackRock allocates expenses tothe Portfolio; (d) the resources devoted to, risk oversight of, and compliance reports relating to, implementation of the Portfolio’s investment objective, policies andrestrictions, and meeting regulatory requirements; (e) BlackRock and the Master Fund’s adherence to applicable compliance policies and procedures; (f) the nature,character and scope of non-investment management services provided by BlackRock and its affiliates and the estimated cost of such services; (g) BlackRock’s and otherservice providers’ internal controls and risk and compliance oversight mechanisms; (h) BlackRock’s implementation of the proxy voting policies approved by the Board;(i) the use of brokerage commissions and execution quality of portfolio transactions; (j) BlackRock’s implementation of the Master Fund’s valuation and liquidityprocedures; (k) an analysis of management fees for products with similar investment mandates across the open-end fund, exchange-traded fund (“ETF”), closed-end fund,sub-advised mutual fund, separately managed account, collective investment trust, and institutional separate account product channels, as applicable, and the similaritiesand differences between these products and the services provided as compared to the Portfolio; (l) BlackRock’s compensation methodology for its investmentprofessionals and the incentives and accountability it creates, along with investment professionals’ investments in the fund(s) they manage; and (m) periodic updates onBlackRock’s business.

Board Considerations in Approving the Agreement

The Approval Process: Prior to the April Meeting, the Board requested and received materials specifically relating to the Agreement. The Independent Board Membersare continuously engaged in a process with their independent legal counsel and BlackRock to review the nature and scope of the information provided to better assist itsdeliberations. The materials provided in connection with the April Meeting included, among other things: (a) information independently compiled and prepared byBroadridge Financial Solutions, Inc. (“Broadridge”), based on either a Lipper classification or Morningstar category, regarding the Portfolio’s fees and expenses ascompared with a peer group of funds as determined by Broadridge (“Expense Peers”) and the investment performance of the Portfolio as compared with a peer group offunds (“Performance Peers”) and other metrics, as applicable; (b) information on the composition of the Expense Peers and Performance Peers, and a description ofBroadridge’s methodology; (c) information on the estimated profits realized by BlackRock and its affiliates pursuant to the Agreement and a discussion of fall-out benefitsto BlackRock and its affiliates; (d) a general analysis provided by BlackRock concerning investment management fees received in connection with other types ofinvestment products, such as institutional accounts, sub-advised mutual funds, ETFs, closed-end funds, open-end funds, and separately managed accounts under similarinvestment mandates, as well as the performance of such other products, as applicable; (e) review of non-management fees; (f) the existence, impact and sharing ofpotential economies of scale, if any, with the Portfolio; (g) a summary of aggregate amounts paid by the Portfolio to BlackRock; (h) sales and redemption data regardingthe Portfolio’s shares; and (i) various additional information requested by the Board as appropriate regarding BlackRock’s and the Portfolio’s operations.

At the April Meeting, the Board reviewed materials relating to its consideration of the Agreement. As a result of the discussions that occurred during the April Meeting, andas a culmination of the Board’s year-long deliberative process, the Board presented BlackRock with questions and requests for additional information. BlackRockresponded to these requests with additional written information in advance of the May Meeting.

Disclosure of Investment Advisory Agreement (continued)

At the May Meeting, the Board concluded its assessment of, among other things: (a) the nature, extent and quality of the services provided by BlackRock; (b) theinvestment performance of the Portfolio as compared with Performance Peers and other metrics, as applicable; (c) the advisory fee and the estimated cost of the servicesand estimated profits realized by BlackRock and its affiliates from their relationship with the Portfolio; (d) the Portfolio’s fees and expenses compared to Expense Peers;(e) the sharing of potential economies of scale; (f) fall-out benefits to BlackRock and its affiliates as a result of BlackRock’s relationship with the Portfolio; and (g) otherfactors deemed relevant by the Board Members.

The Board also considered other matters it deemed important to the approval process, such as other payments made to BlackRock or its affiliates relating to securitieslending and cash management, and BlackRock’s services related to the valuation and pricing of portfolio holdings of the Portfolio. The Board noted the willingness ofBlackRock personnel to engage in open, candid discussions with the Board. The Board did not identify any particular information as determinative, and each BoardMember may have attributed different weights to the various items considered.

A. Nature, Extent and Quality of the Services Provided by BlackRock: The Board, including the Independent Board Members, reviewed the nature, extent and qualityof services provided by BlackRock, including the investment advisory services and the resulting performance of the Portfolio. Throughout the year, the Board comparedPortfolio performance to the performance of a comparable group of mutual funds, relevant benchmark, and performance metrics, as applicable. The Board met withBlackRock’s senior management personnel responsible for investment activities, including the senior investment officers. The Board also reviewed the materials providedby the Portfolio’s portfolio management team discussing the Portfolio’s performance and the Portfolio’s investment objective, strategies and outlook.

The Board considered, among other factors, with respect to BlackRock: the number, education and experience of investment personnel generally and the Portfolio’sportfolio management team; BlackRock’s research capabilities; investments by portfolio managers in the funds they manage; portfolio trading capabilities; use oftechnology; commitment to compliance; credit analysis capabilities; risk analysis and oversight capabilities; and the approach to training and retaining portfolio managersand other research, advisory and management personnel. The Board also considered BlackRock’s overall risk management program, including the continued efforts ofBlackRock and its affiliates to address cybersecurity risks and the role of BlackRock’s Risk & Quantitative Analysis Group. The Board engaged in a review of BlackRock’scompensation structure with respect to the Portfolio’s portfolio management team and BlackRock’s ability to attract and retain high-quality talent and create performanceincentives.

In addition to investment advisory services, the Board considered the nature and quality of the administrative and other non-investment advisory services provided to thePortfolio. BlackRock and its affiliates provide the Portfolio with certain administrative, shareholder and other services (in addition to any such services provided to thePortfolio by third parties) and officers and other personnel as are necessary for the operations of the Portfolio. In particular, BlackRock and its affiliates provide the Portfoliowith administrative services including, among others: (i) responsibility for disclosure documents, such as the prospectus, the summary prospectus (as applicable), thestatement of additional information and periodic shareholder reports; (ii) oversight of daily accounting and pricing; (iii) responsibility for periodic filings with regulators;(iv) overseeing and coordinating the activities of other service providers, including, among others, the Portfolio’s custodian, fund accountant, transfer agent, and auditor;(v) organizing Board meetings and preparing the materials for such Board meetings; (vi) providing legal and compliance support; (vii) furnishing analytical and othersupport to assist the Board in its consideration of strategic issues such as the merger, consolidation or repurposing of certain open-end funds; and (viii) performing ormanaging administrative functions necessary for the operation of the Portfolio, such as tax reporting, expense management, fulfilling regulatory filing requirements,overseeing the Portfolio’s distribution partners, and shareholder call center and other services. The Board reviewed the structure and duties of BlackRock’s fundadministration, shareholder services, and legal & compliance departments and considered BlackRock’s policies and procedures for assuring compliance with applicablelaws and regulations.

B. The Investment Performance of the Portfolio and BlackRock: The Board, including the Independent Board Members, also reviewed and considered theperformance history of the Portfolio. In preparation for the April Meeting, the Board was provided with reports independently prepared by Broadridge, which included acomprehensive analysis of the Portfolio’s performance as of December 31, 2018. Broadridge ranks funds in quartiles, ranging from first to fourth, where first is the mostdesirable quartile position and fourth is the least desirable. In connection with its review, the Board received and reviewed information regarding the investmentperformance of the Portfolio as compared to its Performance Peers. The Board and its Performance Oversight Committee regularly review, and meet with Portfoliomanagement to discuss, the performance of the Portfolio throughout the year.

In evaluating performance, the Board focused particular attention on funds with less favorable performance records. The Board also noted that while it found the dataprovided by Broadridge generally useful, it recognized the limitations of such data, including in particular, that notable differences may exist between a fund and thePerformance Peer funds (for example, the investment objective(s) and investment strategies). Further, the Board recognized that the performance data reflects a snapshotof a period as of a particular date and that selecting a different performance period could produce significantly different results. The Board also acknowledged that long-term performance could be impacted by even one period of significant outperformance or underperformance, and that a single investment theme could have the ability toaffect long-term performance disproportionately.

The Board noted that for each of the one-, three- and five-year periods reported, the Portfolio ranked in the first quartile, against its Performance Peers.

C. Consideration of the Advisory/Management Fees and the Estimated Cost of the Services and Estimated Profits Realized by BlackRock and its Affiliates

from their Relationship with the Portfolio: The Board, including the Independent Board Members, reviewed the Portfolio’s contractual advisory fee rate compared withthose of its Expense Peers. The contractual advisory fee rate is shown before taking into account any reimbursements or fee waivers. The Board also compared thePortfolio’s total expense ratio, as well as its actual advisory fee rate, to those of its Expense Peers. The total expense ratio represents a fund’s total net operatingexpenses, including any 12b-1 or non 12b-1 service fees. The total expense ratio gives effect to any expense reimbursements or fee waivers that benefit a fund, and theactual advisory fee rate gives effect to any management fee reimbursements or waivers that benefit a fund. The Board considered the services provided and the feescharged by BlackRock and its affiliates to other types of clients with similar investment mandates, as applicable, including institutional accounts and sub-advised mutualfunds (including mutual funds sponsored by third parties).

Disclosure of Investment Advisory Agreement (continued)

The Board received and reviewed statements relating to BlackRock’s financial condition. The Board reviewed BlackRock’s profitability methodology and was also providedwith an estimated profitability analysis that detailed the revenues earned and the expenses incurred by BlackRock for services provided to the Portfolio. The Boardreviewed BlackRock’s estimated profitability with respect to the Portfolio and other funds the Board currently oversees for the year ended December 31, 2018 compared toavailable aggregate estimated profitability data provided for the prior two years. The Board reviewed BlackRock’s estimated profitability with respect to certain other U.S.fund complexes managed by the Manager and/or its affiliates. The Board reviewed BlackRock’s assumptions and methodology of allocating expenses in the estimatedprofitability analysis, noting the inherent limitations in allocating costs among various advisory products. The Board recognized that profitability may be affected bynumerous factors including, among other things, fee waivers and expense reimbursements by the Manager, the types of funds managed, precision of expense allocationsand business mix. The Board thus recognized that calculating and comparing profitability at individual fund levels is difficult.

The Board noted that, in general, individual fund or product line profitability of other advisors is not publicly available. The Board reviewed BlackRock’s overall operatingmargin, in general, compared to that of certain other publicly-traded asset management firms. The Board considered the differences between BlackRock and these otherfirms, including the contribution of technology at BlackRock, BlackRock’s expense management, and the relative product mix.

In addition, the Board considered the estimated cost of the services provided to the Portfolio by BlackRock, and BlackRock’s and its affiliates’ estimated profits relating tothe management of the Portfolio and the other funds advised by BlackRock and its affiliates. As part of its analysis, the Board reviewed BlackRock’s methodology inallocating its costs of managing the Portfolio, to the Portfolio. The Board considered whether BlackRock has the financial resources necessary to attract and retain highquality investment management personnel to perform its obligations under the Agreement and to continue to provide the high quality of services that is expected by theBoard. The Board further considered factors including but not limited to BlackRock’s commitment of time, assumption of risk, and liability profile in servicing the Portfolio,including in contrast to what is required of BlackRock with respect to other products with similar investment mandates across the open-end fund, ETF, closed-end fund,sub-advised mutual fund, separately managed account, collective investment trust, and institutional separate account product channels, as applicable.

The Board noted that the Portfolio’s contractual advisory fee rate ranked in the first quartile, and that the actual advisory fee rate and total expense ratio each ranked in thefirst quartile, relative to the Portfolio’s Expense Peers. The Board also noted that the Portfolio has an advisory fee arrangement that includes breakpoints that adjust thefee rate downward as the size of the Portfolio increases above certain contractually specified levels. The Board noted that if the size of the Portfolio were to decrease, thePortfolio could lose the benefit of one or more breakpoints. The Board additionally noted that BlackRock has voluntarily agreed to waive a portion of its administration andadvisory fees payable by the Portfolio. The Board further noted that BlackRock and its affiliates have contractually agreed to reimburse or otherwise compensate thePortfolio for certain other fees and expenses.

D. Economies of Scale: The Board, including the Independent Board Members, considered the extent to which economies of scale might be realized as the assets of thePortfolio increase, including the existence of fee waivers and/or expense caps, as applicable, noting that any contractual fee waivers and expense caps had beenapproved by the Board. The Board also considered the extent to which the Portfolio benefits from such economies in a variety of ways and whether there should bechanges in the advisory fee rate or breakpoint structure in order to enable the Portfolio to more fully participate in these economies of scale. The Board considered thePortfolio’s asset levels and whether the current fee schedule was appropriate. In its consideration, the Board Members took into account the existence of any expensecaps and further considered the continuation and/or implementation, as applicable, of such caps.

E. Other Factors Deemed Relevant by the Board Members: The Board, including the Independent Board Members, also took into account other ancillary or “fall-out”benefits that BlackRock or its affiliates may derive from BlackRock’s respective relationships with the Portfolio, both tangible and intangible, such as BlackRock’s ability toleverage its investment professionals who manage other portfolios and risk management personnel, an increase in BlackRock’s profile in the investment advisorycommunity, and the engagement of BlackRock’s affiliates as service providers to the Portfolio, including for administrative, distribution, securities lending and cashmanagement services. The Board also considered BlackRock’s overall operations and its efforts to expand the scale of, and improve the quality of, its operations. TheBoard also noted that, subject to applicable law, BlackRock may use and benefit from third party research obtained by soft dollars generated by certain registered fundtransactions to assist in managing all or a number of its other client accounts.

In connection with its consideration of the Agreement, the Board also received information regarding BlackRock’s brokerage and soft dollar practices. The Board receivedreports from BlackRock which included information on brokerage commissions and trade execution practices throughout the year.

The Board noted the competitive nature of the open-end fund marketplace, and that shareholders are able to redeem their Portfolio shares if they believe that thePortfolio’s fees and expenses are too high or if they are dissatisfied with the performance of the Portfolio.

Conclusion

The Board, including the Independent Board Members, unanimously approved the continuation of the Agreement between the Manager and the Master Fund, on behalf ofthe Portfolio, for a one-year term ending June 30, 2020. Based upon its evaluation of all of the aforementioned factors in their totality, as well as other information, theBoard, including the Independent Board Members, was satisfied that the terms of the Agreement were fair and reasonable and in the best interest of the Portfolio and itsshareholders. In arriving at its decision to approve the Agreement, the Board did not identify any single factor or group of factors as all-important or controlling, butconsidered all factors together, and different Board Members may have attributed different weights to the various factors considered. The Independent Board Memberswere also assisted by the advice of independent legal counsel in making this determination.
