(each, a “Fund” and collectively, the “Funds”)

Supplement dated July 29, 2019 to the Statement of Additional Information (“SAI”) of each Fund

Effective immediately, each SAI is amended as follows:

The subsections entitled “Right of Accumulation” and “Letter of Intent” in the section entitled “Purchase of Shares—Reduced Initial Sales Charges” in Part II of each Fund’s SAI are deleted in their entirety and replaced with the following:

Right of Accumulation. Investors have a “right of accumulation” under which any of the following may be combined with the amount of the current purchase in determining whether an investor qualifies for a breakpoint and a reduced front-end sales charge:(i) the current value of an investor’s existing Investor A, Investor A1, Investor C, Investor C1, Investor C2, Investor C3, Investor P, Institutional, Class K and Premier Shares in most BlackRock Funds, (ii) the current value of an investor’s existing shares of certain unlisted closed-end management investment companies sponsored and advised by BlackRock or its affiliates (“Eligible Unlisted

-2-

BlackRock Closed-End Funds”) and (iii) the investment in the BlackRock CollegeAdvantage 529 Program by the investor or by or on behalf of the investor’s spouse and children. Financial intermediaries may value current holdings of their customers differently for purposes of determining whether an investor qualifies for a breakpoint and a reduced front-end sales charge, although customers of the same financial intermediary will be treated similarly. In order to use this right, the investor must alert BlackRock to the existence of any previously purchased shares. Certain funds employ a “passive” management approach and attempt to match the performance of a target index as closely as possible before the deduction of Fund expenses (“Index Funds”). Although Investor A Shares of Index Funds and BlackRock Short Obligations Fund generally are not subject to a sales charge, an investor’s existing Investor A, Investor A1, Investor C, Investor C1, Investor C2, Investor C3, Investor P, Institutional, Class K and Premier Shares in the Index Funds and BlackRock Short Obligations Fund may be combined with the amount of an investor’s current purchase in determining whether an investor qualifies for a breakpoint and a reduced front-end sales charge.

Letter of Intent. An investor may qualify for a reduced front-end sales charge immediately by signing a “Letter of Intent” stating the investor’s intention to make one or more of the following investments within the next 13 months which would, if bought all at once, qualify the investor for a reduced sales charge: (i) buy a specified amount of Investor A, Investor C, Investor P, Institutional, Class K and/or Premier Shares, (ii) make an investment in one or more Eligible Unlisted BlackRock Closed-End Funds and/or (iii) make an investment through the BlackRock CollegeAdvantage 529 Program in one or more BlackRock Funds. The initial investment must meet the minimum initial purchase requirement. The 13-month Letter of Intent period commences on the day that the Letter of Intent is received by the Fund. The market value of current holdings in the BlackRock Funds (including Investor A, Investor C, Investor P, Institutional, Class K and Premier Shares, Eligible Unlisted BlackRock Closed-End Funds and the BlackRock CollegeAdvantage 529 Program Class A and Class C Units) as of the date of commencement that are eligible under the Right of Accumulation may be counted towards the sales charge reduction. The investor must notify the Fund of (i) any current holdings in the BlackRock Funds, Eligible Unlisted BlackRock Closed-End Funds and/or the BlackRock CollegeAdvantage 529 Program that should be counted towards the sales charge reduction and (ii) any subsequent purchases that should be counted towards the Letter of Intent. During the term of the Letter of Intent, the Fund will hold Investor A Shares and/or Investor P Shares, as applicable, representing up to 5% of the indicated amount in an escrow account for payment of a higher sales load if the full amount indicated in the Letter of Intent is not purchased. If the full amount indicated is not purchased within the 13-month period, and the investor does not pay the higher sales load within 20 days, the Fund will redeem enough of the Investor A Shares and/or Investor P Shares, as applicable, held in escrow to pay the difference.

Shareholders should retain this Supplement for future reference.
