Call script sequence for reference

Shareholder answers:

Good morning/afternoon/evening. This is [your name] calling from Vanguard on a recorded line.

May I please speak with Mr./Mrs./Ms. [state shareholder’s first and last name]

Moving into the reason for the call:

How are you doing today?

Do you have a moment to speak?

Yes

o	First, let me begin by thanking you for entrusting Vanguard with your investments. I am calling to follow-up on the Vanguard proxy materials sent to you by [state how shareholder received e-delivery or mail]. Have you had the opportunity to review them?

Yes

o	Are there any questions that I can help answer for you regarding the proposals contained in the proxy materials (have proxy resources ready)?

Yes

I can provide information for you about the proposal(s). Vanguard plans to hold a special shareholder meeting on January 22, 2021, so that shareholders of six U.S.-domiciled funds can vote on important proposals affecting their funds. The meeting will be held virtually. Ahead of the meeting, the funds will conduct a proxy campaign to encourage shareholders to vote.

You are being asked to vote on (describe the proposal(s) applicable to the shareholder):

Merger of two value funds—The proposed merger of Vanguard U.S. Value Fund into Vanguard Value Index Fund. Vanguard’s fund trustees determined that a merger was in the best interest of shareholders, as it would place U.S. Value shareholders in a comparable fund with better historical long-term investment performance and offer them a large expense ratio reduction, while shareholders of both funds would benefit from additional economies of scale. The fund’s board of trustees will recommend a vote FOR this proposal.

Change in diversification status of five funds

—The proposed reclassification of Vanguard Health Care Fund, Vanguard Energy Fund, Vanguard U.S. Growth Fund, Vanguard Variable Insurance Funds—Growth Portfolio, and Vanguard Variable Insurance Funds—Real Estate Index Portfolio as “non-diversified” under the Investment Company Act of 1940. We believe that reclassifying the funds as non-diversified is in the best interests of the funds and their shareholders, as it gives the funds’ portfolio managers increased investment flexibility and potential for better investment performance. Notwithstanding the potential for improved investment performance, a non-diversified fund typically presents a heightened degree of investment risk due to its ability to make more concentrated investments. Each fund’s board of trustees will recommend a vote FOR this proposal.

Important information about our shareholder vote

Dear Shareholder,

Vanguard opened an important proxy voting campaign on October 30, 2020, where shareholders are being asked to approve several changes across our U.S. fund lineup. Voting ends January 22, 2021.

We want to make you aware of some communications related to this effort:

·	Voting materials and instructions were sent to shareholders on October 30 by regular mail or email, based on your preference. You may vote online, by phone, or by mail.

We've partnered with Computershare Fund Services as our authorized agent for proxy voting and tabulation services. If you vote online, you'll be directed to a secure personalized online proxy ballot hosted on Computershare's website. If you prefer to cast your vote by phone, please call 1-888-218-4371. For general proxy voting questions, you can speak with a Computershare representative at 866-963-5746.

·	Separate ballots were delivered for mutual fund and brokerage accounts, as well as any annuity holdings you may have. While those communications may look similar, you must vote each separate ballot for your vote to count for those shares and units.

·	During the voting period, you may receive a phone call from Computershare on behalf of Vanguard. Computershare will be periodically calling our shareholders to encourage participation in the voting effort.

By voting promptly, you help minimize the need for additional communications to solicit sufficient shareholder participation, which can be costly for the funds and, therefore, for you as a shareholder.

Thank you for belonging to the Vanguard community of investors.
