Vanguard Funds

Supplement to the Prospectus

Prospectus Text Changes

The following replaces similar text for the second bullet point under the heading “Frequent Trading or Market-Timing” in the More on the Fund(s) section:

• Each Vanguard fund (other than money market funds and short-term bond funds, but including Vanguard Short-Term Inflation-Protected Securities Index Fund) generally prohibits a contract owner or annuitant from exchanging into a fund contract for 30 calendar days after the contract owner or annuitant has exchanged out of that fund contract.
