Type Fund
The fund itself has not been rated by an independent rating agency. 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.

Notional value represents a fund’s use of derivatives, including but not limited to futures, options, and swaps. This value captures the fund exposures as if the derivative was replaced with the underlying asset and the corresponding financing or lending, such that all exposures sum to the net asset value. For non-derivatives, the market value and the notional value are identical.

Allocations are subject to change.
