Supplement to Prospectuses Dated May 1, 2020

The Board of Directors of each fund has approved a change to each fund’s diversification policy under the Investment Company Act of 1940. Under the revised policy, effective September 24, 2020, each fund will continue to seek to track its benchmark index even if the fund becomes nondiversified (as defined under the Investment Company Act of 1940) as a result of a change in relative market capitalization or index weighting of one or more constituents of the index. Shareholder approval will not be sought if the fund crosses from diversified to nondiversified status under such circumstances.

Accordingly, effective September 24, 2020, section 1 of each fund’s prospectus is supplemented to add the following under the heading “Principal Investment Strategies”:

The fund intends to be diversified in approximately the same proportion as the index is diversified. The fund may become “nondiversified,” as defined under the Investment Company Act of 1940, solely as a result of a change in relative market capitalization or index weighting of one or more constituents of the index.

Effective September 24, 2020, the following is added under the heading “Principal Risks” in section 1 of each fund’s prospectus:

Nondiversification The fund may become nondiversified, and thus invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the fund’s performance may be adversely affected, the fund’s shares may experience greater price volatility; and the fund may be more susceptible to the risks associated with these particular issuers or to a single economic, political, or regulatory occurrence affecting these issuers.

Section 2 of each fund’s prospectus is supplemented to add the following under the heading “Principal Investment Strategies”, effective September 24, 2020:

The fund intends to be diversified in approximately the same proportion as the index is diversified. The fund may become “nondiversified,” as defined in the Investment Company Act of 1940, solely as a result of a change in relative market capitalization or index weighting of one or more constituents of the index. Shareholder approval will not be sought if the fund becomes

“nondiversified” due solely to a change in the relative market capitalization or index weighting of one or more constituents of the index.

The following is added under the heading “Principal Investment Strategies” in section 2 of each fund’s prospectus, effective September 24, 2020:

Nondiversification The fund may, from time to time, become nondiversified and thus invest more of its assets in a smaller number of issuers. A nondiversified fund is more exposed to the risks associated with an individual issuer than a fund that invests more broadly across many issuers. For example, poor performance by a single large holding of the fund would adversely affect the fund’s performance more than if the fund were invested in a larger number of issuers.

The date of this supplement is August 17, 2020.
