RULE 12d1-4

FUND OF FUNDS INVESTMENT AGREEMENT

THIS AGREEMENT, dated as of January 19, 2022, as amended on April 1, 2022, among each of the Trusts listed on Schedule A (each, a "Trust" and collectively, the "Trusts"), on behalf of each series of the Trusts listed on Schedule A, severally and not jointly (each, an "Investing Fund" and collectively, the "Investing Funds"), and each Vanguard Fund, severally and not jointly (each, a "Vanguard Fund" and together with the Investing Funds, the "Funds"), listed on Schedule A.

WHEREAS, each Fund is registered with the U.S. Securities and Exchange Commission ("SEC") as an investment company under the Investment Company Act of 1940, as amended, (the "1940 Act");

WHEREAS, Section 12(d)(1)(A) of the 1940 Act limits the extent to which a registered investment company may invest in shares of other registered investment companies, Section 12(d)(1)(B) limits the extent to which a registered open-end investment company, its principal underwriter ("Distributor") or registered brokers or dealers ("Brokers") may knowingly sell shares of such registered investment company to other investment companies, and Section 12(d)(1)(C) limits the extent to which an investment company may invest in the shares of a registered closed-end investment company;

WHEREAS, Rule 12d1-4 under the 1940 Act (the "Rule") permits (i) registered investment companies, such as the Investing Funds, to invest in shares of other registered investment companies, such as the Vanguard Funds, in excess of the limits of Section 12(d)(1)(A) of the 1940 Act, and (ii) registered investment companies, such as the Vanguard Funds, as well as the Distributor and Brokers, knowingly to sell shares of the Vanguard Funds to the Investing Funds in excess of the limits of Section 12(d)(1)(B) of the 1940 Act, subject to compliance with the conditions of the Rule;

WHEREAS, an Investing Fund may, from time to time, invest in shares of one or more Vanguard Funds in excess of the limitations of Section 12(d)(1)(A) in reliance on the Rule; and

WHEREAS, a Vanguard Fund, Distributor, or Broker, from time to time, may knowingly sell Shares of one or more Vanguard Funds to an Investing Fund in excess of the limitations of Section 12(d)(1)(B) in reliance on the Rule;

NOW THEREFORE, in accordance with the Rule, the Investing Funds and the Vanguard Funds desire to set forth the following terms pursuant to which the Investing Funds may invest in the Vanguard Funds in reliance on the Rule and the Vanguard Funds, Distributor, or Broker may sell shares of the Vanguard Funds to the Investing Funds in reliance on the Rule.

1.Terms of Investment

(a)With respect to investments in Vanguard Funds that operate as exchange-traded funds ("Vanguard ETFs"), the Funds note that each Vanguard ETF is designed to accommodate large investments and redemptions, whether from Investing Funds or other investors. Creation and redemption orders for shares of the Vanguard ETFs can only be submitted by Brokers or other participants of a registered clearing agency (collectively, "Authorized Participants") that have entered into an agreement ("Authorized Participant Agreement") with the Vanguard ETFs' distributor to transact in shares of the Vanguard ETFs. The Vanguard ETFs also have policies and procedures (the "Basket Policies") that have been adopted pursuant to Rule 6c-11 under the 1940 Act, which govern creations and redemptions of the Vanguard ETFs' shares. Any creation or redemption order submitted by an Investing Fund through an Authorized Participant will be satisfied pursuant to the Basket Policies and the relevant Authorized Participant Agreement. The Basket Policies include provisions that govern in-kind creations and redemptions, as well as cash transactions. In any event, the Funds generally expect that the Investing

Funds will transact in shares in the Vanguard ETFs on the secondary market rather than through direct creation and redemption transactions with the Vanguard ETF. The Funds believe that these material terms regarding an Investing Fund's investment in shares of a Vanguard ETF should assist the Vanguard ETF's investment adviser, the Vanguard Group Inc. ("Vanguard), with making the required findings under the Rule.

(b)In order to help reasonably address the risk of undue influence on a Vanguard Fund that operates as a mutual fund ("Vanguard Mutual Fund") by an Investing Fund, and to assist Vanguard with making the required findings under the Rule, each Investing Fund and each Vanguard Mutual Fund agree as follows:

(i)In-kind redemptions. The Investing Fund acknowledges and agrees that, if and to the extent consistent with the Vanguard Mutual Fund's registration statement, as amended from time to time, the Vanguard Mutual Fund may honor any redemption request partially or wholly in-kind.

(ii)Timing/advance notice of redemptions. The Investing Fund will use reasonable efforts to spread large redemption requests over multiple days or to provide advance notification of redemption requests to the Vanguard Mutual Fund(s) whenever practicable and only if consistent with the Investing Fund's and its shareholders' best interests. The Vanguard Mutual Fund acknowledges and agrees that any notification provided pursuant to the foregoing is not a commitment to redeem and constitutes an estimate that may differ materially from the amount, timing and manner in which a redemption request is submitted, if any.

(iii)Scale of investment. Upon a reasonable request by a Vanguard Mutual Fund, the Investing Fund will provide summary information regarding the anticipated timeline of its investment in the Vanguard Mutual Fund and the scale of its contemplated investments in the Vanguard Mutual Fund.

(c)In order to assist the Investing Fund's investment adviser with evaluating the complexity of the structure and fees and expenses associated with an investment in a Vanguard Fund, each Vanguard Fund shall provide each Investing Fund with information on the fees and expenses of the Vanguard Fund reasonably requested by the Investing Fund with reference to the Rule.

2.Representations of the Vanguard Funds.

In connection with any investment by an Investing Fund in a Vanguard Fund in excess of the limitations in Section 12(d)(1)(A) or knowing sale of shares by a Vanguard Fund, Distributor, or Broker to an Investing Fund in excess of the limitations in Section 12(d)(1)(B), the Vanguard Fund agrees to:

(i)comply with all conditions of the Rule, as interpreted or modified by the SEC or its Staff from time to time, applicable to Vanguard Funds; (ii) comply with its obligations under this Agreement; and (iii) promptly notify the Investing Fund if such Vanguard Fund fails to comply with the Rule with respect to an investment by the Investing Fund, as interpreted or modified by the SEC or its Staff from time to time, or this Agreement. A Vanguard Fund will also notify the Investing Fund promptly if such Vanguard Fund purchases or otherwise acquires the securities of an investment company or private fund in contravention of Rule 12d1-4(b)(3)(ii).

3.Representations of the Investing Funds.

In connection with any investment by an Investing Fund in a Vanguard Fund in excess of the limitations in Section 12(d)(1)(A) or knowing sale of Shares by a Vanguard Fund, Distributor, or Broker to an Investing Fund in excess of the limitations in Section 12(d)(1)(B), the Investing Fund agrees to: (i) comply with all conditions of the Rule, as interpreted or modified by the SEC or its Staff from time to time, applicable

to Investing Funds; (ii) comply with its obligations under this Agreement; (iii) promptly notify the Vanguard Fund when it has invested in the Vanguard Fund in an amount which exceeds the limitations in Section 12(d)(1)(A); and (iv) promptly notify the Vanguard Fund if such Investing Fund fails to comply with the Rule with respect to its investment in such Vanguard Fund, as interpreted or modified by the SEC or its Staff from time to time, or this Agreement.

4.Indemnification.

(a)Each Investing Fund, severally and not jointly, agrees to hold harmless, indemnify and defend the Vanguard Funds, including any principals, directors or trustees, officers, employees and agents ("Vanguard Agents"), against and from any and all losses, costs, expenses or liabilities incurred by or claims or actions ("Claims") asserted against the Vanguard Fund, including any Vanguard Agents, to the extent such Claims result from (i) a violation or alleged violation of any provision of this Agreement or (ii) a violation or alleged violation of the terms and conditions of the Rule, as applicable, in each case by the Investing Fund, its principals, directors or trustees, officers, employees, agents, advisers or if applicable, subadvisers.

(b)The Vanguard Funds, severally and not jointly, agree to hold harmless, indemnify and defend each Investing Fund, including any principals, directors or trustees, officers, employees and agents ("Investing Fund Agents"), against and from any and all losses, costs, expenses or liabilities incurred by or Claims asserted against an Investing Fund, including any Investing Fund Agents, to the extent such Claims result from (i) a violation or alleged violation of any provision of this Agreement or (ii) a violation or alleged violation of the terms and conditions of the Rule, as applicable, in each case by the Vanguard Fund, its principals, directors or trustees, officers, employees, agents or advisers.

(c)Any indemnification pursuant to this Section shall include any reasonable counsel fees and expenses incurred in connection with investigating and/or defending the applicable Claims. In any action involving the Vanguard Funds under this Agreement, each Investing Fund agrees to look solely to the individual Vanguard Fund(s) that are involved in the matter in controversy and not to any other series of the Vanguard Funds.
