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

Supplement dated February 28, 2020 to the Investor A and/or Investor C Shares Prospectus of each Fund (each, a “Prospectus”)

The following is added to the end of the section of each Prospectus entitled “Intermediary-Defined Sales Charge Waiver Policies”:

Janney Montgomery Scott LLC:

Effective May 1, 2020, if you purchase fund shares through a Janney Montgomery Scott LLC (“Janney”) brokerage account, you will be eligible for the following sales charge waivers (front-end sales charge waivers and contingent deferred sales charge (“CDSC”), or back-end sales charge, waivers) and discounts, which may differ from those disclosed elsewhere in this Fund’s prospectus or SAI.

Front-end sales charge* waivers on Investor A shares available at Janney

∎ Shares purchased through reinvestment of capital gains distributions and dividend reinvestment when purchasing shares of the same fund (but not any other BlackRock Fund).

∎ Shares purchased by employees and registered representatives of Janney or its affiliates and their family members as designated by Janney.

∎ Shares purchased from the proceeds of redemptions from another BlackRock Fund, provided (1) the repurchase occurs within ninety (90) days following the redemption, (2) the redemption and purchase occur in the same account, and (3) redeemed shares were subject to a front-end or deferred sales charge (i.e., right of reinstatement).

∎ Employer-sponsored retirement plans (e.g., 401(k) plans, 457 plans, employer-sponsored 403(b) plans, profit sharing and money purchase pension plans and defined benefit plans). For purposes of this provision, employer-sponsored retirement plans do not include SEP IRAs, Simple IRAs, SAR-SEPs or Keogh plans.

∎ Shares acquired through a right of reinstatement.

∎ Investor C shares that are no longer subject to a contingent deferred sales charge and are converted to Investor A shares of the same fund pursuant to Janney’s policies and procedures.

- 2 -

CDSC waivers on Investor A and C shares available at Janney

∎ Shares sold upon the death or disability of the shareholder.

∎ Shares sold as part of a systematic withdrawal plan as described in the Fund’s prospectus or SAI.

∎ Shares purchased in connection with a return of excess contributions from an IRA account.

∎ Shares sold as part of a required minimum distribution for IRA and retirement accounts pursuant to the Internal Revenue Code.

∎ Shares sold to pay Janney fees but only if the transaction is initiated by Janney.

∎ Shares acquired through a right of reinstatement.

∎ Shares exchanged into the same share class of a different fund.

Front-end sales charge* discounts available at Janney: breakpoints, rights of accumulation, and/or letters of intent

∎ Breakpoints as described in the Fund’s prospectus or SAI.

∎ Rights of accumulation (“ROA”), which entitle shareholders to breakpoint discounts, will be automatically calculated based on the aggregated holding of BlackRock Fund assets held by accounts within the purchaser’s household at Janney. Eligible BlackRock Fund assets not held at Janney may be included in the ROA calculation only if the shareholder notifies his or her financial advisor about such assets.

∎ Letters of intent which allow for breakpoint discounts based on anticipated purchases within a BlackRock Fund, over a 13-month time period. Eligible BlackRock Fund assets not held at Janney Montgomery Scott may be included in the calculation of letters of intent only if the shareholder notifies his or her financial advisor about such assets.

*Also referred to as an “initial sales charge.”

Shareholders should retain this Supplement for future reference.
