Notes to financial statements

Each of the collective investment funds included in this report (individually, a “Fund”, and collectively, the “Funds”)is a trust maintained by BlackRock Institutional Trust Company, N.A. (“BTC”), which serves as trustee of theFunds. Each Fund is an entity that is legally separate from BTC, other collective investment funds, and theinvesting unitholders. The Funds are established under a plan document, as amended from time to time, which isnot within the scope of the audit, and sets forth the terms under which BTC manages and administers the Funds’assets.

Each Fund invests in one or more other collective investment funds (each, an “underlying fund”, and collectively,the “underlying funds”) to seek to meet its investment objectives. The plan document and the financial statementsof the underlying funds, both made available by BTC, provide information about the investment strategy andredemption terms of the underlying funds and should be read in conjunction with each Fund’s financialstatements. Investments in the underlying funds are presented in each Fund’s schedule of investments.

1. Significant accounting policies

The following significant accounting policies are consistently followed by each Fund in the preparation of itsfinancial 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 tomake certain estimates and assumptions that affect the reported amounts of assets and liabilities at the date ofthe financial statements and the reported amounts of revenues and expenses during the reporting period. Actualresults could differ from those estimates. Each Fund is considered an investment company under U.S. GAAP andfollows the accounting and reporting guidance applicable to investment companies.

A. Valuation – Valuation of each Fund’s units occurs, at a minimum, each day the Fund is open for contributionsand redemptions and, for financial reporting purposes, as of the report date should the reporting period end on aday that the Fund is not open (each, a “valuation date”). Unit values are determined by dividing each Fund’s netassets by the number of units outstanding on the valuation date. Each Fund’s investments are valued at fair valueeach valuation date.

U.S. GAAP defines fair value as the price a fund would receive to sell an asset or pay to transfer a liability in anorderly transaction between market participants at the valuation date. The BlackRock Global ValuationMethodologies Committee (the “Global Valuation Committee”) provides oversight of the valuation of investmentsfor the Funds. The investments of each Fund are valued pursuant to the policies and procedures developed bythe Global Valuation Committee and approved by BTC (“BlackRock’s global valuation policy”).

Units of collective investment funds, including short term investment funds, are valued based on the unit valuedetermined for each fund on the valuation date.

In the event that application of these methods of valuation results in a price for an investment which is deemednot to be representative of the fair value of such investment or if a price is not available, the investment will bevalued by the Global Valuation Committee, in accordance with BlackRock’s global valuation policy. The fairvaluation approaches that may be utilized by the Global Valuation Committee to determine fair value includemarket approach, income approach and cost approach. The valuation techniques used under these approachestake into consideration inputs that include but are not limited to (i) attributes specific to the investment; (ii) theprincipal 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 forsimilar 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 default rates.

BLACKROCK®60 December 31, 2017

Notes to financial statements

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

Various inputs are used in determining the fair value of financial instruments. Inputs may be based onindependent 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 forfinancial reporting purposes as follows:

Level 1 Unadjusted quoted prices 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 orliability either directly or indirectly, including quoted prices for similar assets or liabilities inmarkets that are active, quoted prices for identical or similar assets or liabilities in markets thatare not active, inputs other than quoted prices that are observable for the assets or liabilities(such as exchange rates, financing terms, interest rates, yield curves, volatilities, prepaymentspeeds, loss severities, credit risks and default rates) or other market–corroborated inputs; and

Level 3 Unobservable inputs for the asset or liability based on the best information available in thecircumstances, to the extent observable inputs are not available, including the Global ValuationCommittee’s assumptions used in determining the fair value of investments.

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets orliabilities (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 inLevel 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In suchcases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level inputthat is significant to the fair value measurement in its entirety.

Changes in valuation techniques may result in transfers in or out of an assigned level within the fair valuehierarchy. Transfers between different levels of the fair value hierarchy are deemed to have occurred as of thebeginning of the reporting period. The categorization of values determined for financial instruments are based onthe pricing transparency of the financial instruments and are not necessarily an indication of the risks associatedwith investing in those securities.

As of December 31, 2017, the value of each of the Funds’ investments was classified as Level 2. The breakdownof each Fund’s investments into major categories is disclosed in its respective schedule of investments.

B. Security transactions and income recognition – Security transactions are accounted for on trade date. Interestincome and interest expense are accounted for on an accrual basis. Distributions from short term investment funds arerecognized on the ex-dividend date. Realized gains and losses are determined on a first-in, first-out (FIFO) cost basisas a specific identification cost relief method. Realized gains and losses reported by a fund may include a componentattributable to the fund’s pro-rata share of net realized gain or loss recognized by underlying funds.

Collective fund income represents the investing fund’s pro-rata share of net investment income (loss) fromunderlying funds. Collective fund income, as earned, is reinvested as of each valuation date. The components ofcollective fund income include interest income, dividend income, distributions from short term investment fundsreceived from underlying funds, withholding taxes, and expenses, as applicable. The investing fund’s pro-ratashare of the securities lending income from underlying funds is disclosed separately from collective fund incomeand is shown net of interest rebates and securities lending agent fees.

BLACKROCK®61 December 31, 2017

Notes to financial statements

C. Distribution of income – Net investment income and net realized gains are not distributed.

D. Contributions and redemptions of units – The value of units upon contribution to or redemption from a Fund isbased on the Fund’s unit value determined on that day. A unitholder’s ability to contribute to or redeem from eachFund occurs on a daily basis on a day BTC is open for business.

Unitholders may, at BTC’s discretion, contribute securities or other assets in lieu of cash (“in-kind contributions”) orredeem securities and/or units of underlying funds (“in-kind redemptions”) and will be charged any expenses and fees, asagreed, of the transfer. In-kind contributions and in-kind redemptions are priced in accordance with BlackRock’s globalvaluation policy and any expenses and fees, as agreed, of the transfer may be deducted from the contribution orredemption amount. For purposes of U.S. GAAP, these in-kind redemption transactions are treated as a sale of securitiesand the resulting gains and losses are recognized based on the market value of the securities on the date of the transfer.

E. Unitholders’ net assets – Each Fund’s unitholders have an undivided interest in the Fund’s net assets.Unitholders’ interests are represented by accounting entries in each Fund’s records as “units” and are notcertificated. Each Fund may issue an unlimited number of units, and units have no preferences as to conversion,transfer, dividend or redemption.

F. Income taxes – Each Fund complies with the requirements of the Federal and California tax authorities for exemptionfrom income taxes and, accordingly, no tax provision is required. BTC has analyzed tax laws and regulations and theirapplication to the Funds as of December 31, 2017, inclusive of the open tax return years, and does not believe there areany uncertain tax positions that require recognition of a tax liability in the Funds’ financial statements.

G. Expenses – Expenses are accounted for on an accrual basis. Expenses directly related to a Fund are chargedto that Fund. Other operating expenses shared by several funds, including other funds managed by BTC, arepro-rated among those funds on the basis of relative net assets or other appropriate methods.

2. Related party transactions

BTC is the trustee of the Funds and provides investment management and fiduciary services for the Funds. BTCis a subsidiary of BlackRock, Inc.

For its services as trustee and investment manager of the Funds, BTC charges investment management fees, accrueddaily, based on the net assets of the Funds. The Funds listed below have investment management fees as follows:

Notes to financial statements

The Funds may incur, directly or indirectly through their investment in underlying funds, operating expenses foradministration (including custody, fund accounting and related services including Form 5500 reporting), audit(including System and Organization Controls 1 Report review and other services), and other third-party expenses,including fees paid for proxy voting services, certain legal expenses, and shareholder servicing fees (paid at thedirection of the investing plan for services provided to the investing plans). BTC has, without recourse, agreed tobear all operating expenses in excess of a certain percent of the Funds’ respective net assets (“net operatingexpense ratio cap”). A Fund’s investment management fees and shareholder servicing fees are not included inthe operating expenses to which the net operating expense ratio cap applies. The effects of these expensearrangements, if any, have been reflected in the statement of operations as operating expenses borne by BTC.Net operating expense ratio caps in effect for the year ended December 31, 2017, were as follows:

3. Securities lending

A fund may earn securities lending income indirectly by its investment in underlying funds that lend securities. Thestatement of operations provides information on securities lending income earned indirectly by a fund. Securitieslending income earned by an underlying fund consists of borrower fees and/or earnings from the investment ofcash collateral posted by borrowers. A portion of the return from investment of cash collateral may be paid to theborrowers of the securities as a negotiated rebate of interest earned on the cash collateral. The remainingsecurities lending income is allocated between the underlying funds and BTC, the securities lending agent. BTCbears all operational costs with respect to securities lending transactions. Securities lending by underlying fundsinvolves exposure to certain risks, including cash collateral reinvestment risk.

4. Commitments and contingencies

In the normal course of business, each Fund enters into contracts that contain a variety of representations whichprovide general indemnifications. The Funds’ maximum exposure under these arrangements is unknown as thiswould involve future claims that may be made against the Funds that have not yet occurred. However, based onexperience, each Fund expects the risk of loss to be remote.

5. Principal risks

In the normal course of business, each Fund’s investment activities expose it to various types of risk associatedwith the financial instruments and markets in which it invests. The significant types of financial risks each Fund isexposed to include, but are not limited to, market risk and credit risk.

BLACKROCK®63 December 31, 2017

Notes to financial statements

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 marketpositions in the face of market movements. Each Fund is exposed to market risk by its investment in underlyingfunds. The financial statements of the underlying funds should be read in conjunction with these financialstatements. The fair value of securities held by a fund may decline due to general market conditions, economictrends or events that are not specifically related to the issuers of the securities including local, regional or globalpolitical, social or economic instability or to factors that affect a particular industry or group of industries. Theextent of a fund’s exposure to market risk is the market value of the investments held as shown in the fund’sschedule of investments.

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

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 tomake timely interest and/or principal payments or to otherwise honor its obligations. BTC’s evaluation of thecreditworthiness of their counterparties may not prove sufficient and the absence of a regulated market tofacilitate settlement may increase the potential for losses by a fund. Financial assets, which potentially expose afund to issuer and counterparty credit risks, consist principally of financial instruments and receivables due fromcounterparties. The extent of each Fund’s exposure to credit and counterparty risks with respect to those financialassets is approximated by its value recorded in the statement of assets and liabilities.

6. Ownership concentration

The following table shows the number of unitholders with interests in excess of 10% of the net assets of therespective fund as of December 31, 2017. Investment activities of such unitholders could have a material impacton the operations of such fund. Such unitholders may be other collective investment funds with diversifiedunitholders.
