Performance data is not currently available
The performance quoted represents past performance and does not guarantee future results. Investment return and principal value of an investment will fluctuate so that an investor's shares, when sold or redeemed, may be worth more or less than the original cost. Current performance may be lower or higher than the performance quoted. The fund's investment advisor may, from time to time, voluntarily waive a portion of its fees. Performance shown reflects these fee waivers and would be lower without such waivers. BFA may discontinue voluntary waivers at any time without notice.

Detailed Holdings and Analytics
Holdings are subject to change.


The values shown for “market value,” “weight,” and “notional value” (the “calculated values”) are based off of a price provided by a third-party pricing vendor for the portfolio holding and do not reflect the impact of systematic fair valuation (“the vendor price”). The vendor price is not necessarily the price at which the Fund values the portfolio holding for the purposes of determining its net asset value (the “valuation price”). Holdings data shown reflects the investment book of record, which may differ from the accounting book of record used for the purposes of determining the Net Assets of the Fund. Notional value represents the portfolio's exposures based on the economic value of investments and options are delta-adjusted. Additionally, where applicable, foreign currency exchange rates with respect to the portfolio holdings denominated in non-U.S. currencies for the valuation price will be generally determined as of the close of business on the New York Stock Exchange, whereas for the vendor price will be generally determined as of 4 p.m. London. The calculated values may have been different if the valuation price were to have been used to calculate such values. The vendor price is as of the most recent date for which a price is available and may not necessarily be as of the date shown above.

Please see the “Determination of Net Asset Value” section of each Fund’s prospectus for additional information on the Fund’s valuation policies and procedures.

% of Market Value

Type Fund

Sector exposure is calculated by aggregating the percent par of individual securities in the portfolio by security type. BlackRock uses a proprietary process to determine the security type of individual securities, by conducting a thorough analysis of the issuer/obligor, including but not limited to any support providers or enhancers. The values reported include cash, accrued income, and/or payables/receivables which may result in negative weightings from specific circumstances (including timing differences between trade and settle dates of securities purchased by the funds). Allocations are subject to change.
