In tax-exempt funds, income may be subject to state and local taxes, as well as the alternative federal minimum tax.

Capital gains, if any, will be subject to taxes. Income for state specific funds may be exempt from state and local taxes for in-state residents only. The information provided is not tax or investment advice. Each investor's tax and investment considerations may be different.

BlackRock does not provide tax advice. Distributions and yields may be affected by: 1) changes in the portfolio as when bonds paying higher interest rates are called or mature and are replaced by bonds paying lower current interest rates and 2) in the case of leveraged funds, by changes in the variable rate paid by the fund for leverage. Current year distributions are not classified as "Income", "Short-Term Capital Gains", "Long Term Capital Gains",

or "Return of Capital" until calendar year-end and may be paid from non-income sources such as return of capital. Note that closed-end funds often trade at a discount to NAV but may trade at a premium.

All other information is reported by BlackRock as of December 31, 2019. Past performance is no guarantee of future results. The price of fund shares will fluctuate so that they may be worth more or less than their original cost.
