Performance is shown after deduction of ongoing charges. Any entry and exit charges are excluded from the calculation.

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 returns for Class K Shares prior to August 15, 2016 reflects the performance of the share class when it was classified as BlackRock Shares. The performance information for periods prior to July 18, 2011, the commencement of operations of Class K Shares (when classified as BlackRock Shares), shows the performance of the Fund’s Institutional Shares. The performance of Class K Shares would be substantially similar to Institutional Shares because Class K Shares and Institutional Shares invest in the same portfolio of securities and performance would differ only to the extent that Institutional Shares and Class K Shares have different expenses.

Effective October 1, 2021, the Bloomberg Municipal Bond Index and a customized weighted index comprised of 90% Bloomberg Municipal Bond Index Total Return Index Value Unhedged / 10% Bloomberg Municipal Bond: High Yield (non-Investment Grade) Total Return Index (the “National Customized Reference Benchmark”) replaced the S&P® Municipal Bond Index and the Custom National Index (a customized benchmark that reflects the returns of the S&P® Municipal Bond Index for periods prior to January 1, 2013, and the returns of only those bonds in the S&P® Municipal Bond Index that have maturities greater than five years for periods subsequent to January 1, 2013)  as the performance benchmarks against which the Fund measures its performance.

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.
