1. SIGNIFICANT ACCOUNTING POLICIES

SECURITY VALUATION

The securities and other assets of each Fund are valued pursuant to the pricing policy and procedures approved by the Board of Trustees of the Trust (the “Board”) using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. Inputs may be based on independent market data (“observable inputs”) or they may be internally developed (“unobservable inputs”). The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows:

 

  •  

Level 1 – Inputs that reflect unadjusted quoted prices in active markets for identical assets or liabilities that the Fund has the ability to access at the measurement date (a “Level 1 Price”);

 

  •  

Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not considered to be active, inputs other than quoted prices that are observable for the asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means (a “Level 2 Price”);

 

  •  

Level 3 – Inputs that are unobservable for the asset or liability (a “Level 3 Price”).

The availability of observable inputs can vary from security to security and is affected by a wide variety of factors, including, for example, the type of security, whether the security is new and not yet established in the marketplace, the liquidity of markets, and other characteristics particular to the security. Inputs may include price information, volatility statistics, specific and broad credit data, liquidity statistics, and other factors. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3 of the fair value hierarchy.

The level of a value determined for a financial instrument within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement in its entirety. The categorization of a value determined for a financial instrument within the hierarchy is based upon the pricing transparency of the instrument and does not necessarily correspond to the Funds’ perceived risk of that instrument.

Investments whose values are based on quoted market prices in active markets, and whose values are therefore classified as Level 1 Prices, include active listed equities. The Funds do not adjust the quoted price for such instruments, even in situations where the Funds hold a large position and a sale could reasonably impact the quoted price.

Investments that trade in markets that are not considered to be active, but whose values are based on inputs such as quoted market prices, dealer quotations or valuations provided by alternative pricing sources supported by observable inputs are classified within Level 2. These generally include U.S. government and sovereign obligations, most government agency securities, investment-grade corporate bonds, certain mortgage products, less liquid listed equities, and state, municipal and provincial obligations. As Level 2 investments include positions that are not traded in active markets and/or are subject to transfer restrictions, valuations may be adjusted to reflect illiquidity and/or non-transferability, which are generally based on available market information.

Investments whose values are classified as Level 3 Prices have significant unobservable inputs, as they may trade infrequently or not at all. Investments whose values are classified as Level 3 Prices may include unlisted securities related to corporate actions, securities whose trading have been suspended or which have been de-listed from their primary trading exchange, less liquid corporate debt securities (including distressed debt instruments), collateralized debt obligations, and less liquid mortgage securities (backed by either commercial or residential real estate). When observable prices are not available for these securities, the Funds use one or more valuation techniques (e.g., the market approach or the income approach) for which sufficient and reliable data is available. Within Level 3 of the fair value hierarchy, the use of the market approach generally consists of using comparable market transactions, while the use of the income approach generally consists of the net present value of estimated future cash flows, adjusted as appropriate for liquidity, credit, market and/or other risk factors.

The inputs used by the Funds in estimating the value of Level 3 Prices may include the original transaction price, recent transactions in the same or similar instruments, completed or pending third-party transactions in the underlying investment or comparable issuers, and changes in financial ratios or cash flows. Level 3 Prices may also be adjusted to reflect illiquidity and/or non-transferability, with the amount of such discount estimated by the Funds in the absence of market information. The fair value measurement of Level 3 Prices does not include transaction costs that may have been capitalized as part of the security’s cost basis. Assumptions used by the Funds due to the lack of observable inputs may significantly impact the resulting fair value and therefore the Funds’ results of operations.

The following table summarizes the values of each Fund’s investments according to the fair value hierarchy as of June 30, 2010. The breakdown of each Fund’s investments into major categories is disclosed in its respective Schedule of Investments.

Each Fund may invest its positive cash balances in certain money market funds managed by BlackRock Fund Advisors (“BFA”) or an affiliate.

3. LOANS OF PORTFOLIO SECURITIES

Each Fund may lend its investment securities to approved borrowers, such as brokers, dealers and other financial institutions. The borrower pledges and maintains with the Fund collateral consisting of cash, an irrevocable letter of credit issued by a bank, or securities issued or guaranteed by the U.S. government. The initial collateral received by each Fund is required to have a value of at least 102% of the market value of the loaned securities plus the interest accrued on such securities, if any, for securities traded on U.S. exchanges and a value of at least 105% for all other securities. The collateral is maintained thereafter, at a value equal to at least 100% of the current market value of the securities on loan plus accrued interest, if any. 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. Any securities lending cash collateral

may be reinvested in certain short-term instruments either directly on behalf of a Fund or through one or more joint accounts or money market funds, including those managed by BFA; such reinvestments are subject to investment risk.

As of June 30, 2010, certain Funds had loaned securities which were collateralized by cash. The cash collateral received was invested in money market funds managed by BFA or an affiliate.
