RE: Vanguard Variable Insurance Funds
File No. 33-32216
Dear Mr. Cowan,
This letter responds to your comments of June 24, 2011 on the Post-Effective Amendment No. 56 of the above-referenced registrant that was filed on May 23, 2010 pursuant to Rule 485(a). The following comments pertain to VVIF Conservative Allocation Portfolio, and VVIF Moderate Allocation Portfolio, each a new series of the registrant.
Comment 1: Prospectus: Fees and Expenses
Comment: As the funds are new, please disclose in a footnote to the table that Acquired Fund Fees and Expenses and Other expenses are based on estimated amounts for the current fiscal year.
Response: We will revise the table in response to your comment.
Comment 2: Prospectus: Fees and Expenses – Example
Comment: Please disclose that the example does not reflect additional fees and expenses associated with the annuity or life insurance program through which you invest and that if such expenses were reflected, expenses would be higher.
Response: The disclosure in the paragraph following the “Fees and Expenses” heading addresses your comment and applies to the entire “Fees and Expenses” section, which includes the example. Accordingly, we do not plan to revise the disclosure.
Comment 3: Prospectus: Primary Risks
Comment: Please include fund-of-funds risk disclosure about the layering of fees described in Item 2.
Response: Item 4 requires "the principal risks of investing in the Fund, including the risks to which the Fund's portfolio as a whole is subject and the circumstances reasonably likely to affect adversely the Fund's net asset value, yield, and total return." Because Vanguard’s funds-of-funds do not layer fees on top of the acquired funds fees, there is no risk to the funds-of-funds. Accordingly, we do not plan to revise the disclosure.
