Most transactions in fixed-rate mortgage pass-through securities occur through the use of "to-be-announced" or "TBA" transactions. The Fund regularly enters into TBA agreements. The Fund invests cash pending settlement of any TBA transactions in money market instruments, repurchase agreements or other high-quality, liquid short-term instruments, including money market funds advised by BFA, which are not included in the holdings shown.

Holdings are subject to change.

Non-U.S. securities whose values are affected by volatility that occurs in global markets or in related or highly correlated assets (e.g., American Depositary Receipts, Global Depositary Receipts or substantially identical ETFs) on a trading day after the close of non-U.S. securities markets may be fair valued. On days where non-U.S. securities markets are closed, BlackRock Fund Advisors, an affiliate of BlackRock Investments, LLC, will determine the fair value of the stocks traded on that local market, in accordance with policies and procedures approved by the Fund’s Board of Directors/Trustees. Fair value adjustments may be calculated by referring to instruments and markets that have continued to trade, such as exchange-traded funds, correlated stock market indices or index futures. 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.

Type Fund
Credit quality ratings on underlying securities of the fund are received from S&P, Moody’s and Fitch and converted to the equivalent S&P major rating category. This breakdown is provided by BlackRock and takes the median rating of the three agencies when all three agencies rate a security, the lower of the two ratings if only two agencies rate a security, and one rating if that is all that is provided. Unrated securities do not necessarily indicate low quality. Below investment-grade is represented by a rating of BB and below. Ratings and portfolio credit quality may change over time.
