Vanguard Target Retirement Funds

Supplement to the Prospectus Dated January 28, 2013

Important Changes to the Vanguard Target Retirement Funds

The board of trustees of the Vanguard Target Retirement Funds has approved the following changes to the fixed income exposure of the Funds.

• Twenty percent of each Fund’s fixed income exposure (currently domestic bonds and, in the case of the Target Retirement Income and Target Retirement 2010 Funds, money market instruments) will be reallocated to foreign bonds through investment in Vanguard Total International Bond Index Fund.

• The Target Retirement Income, Target Retirement 2010, and Target Retirement 2015 Funds will obtain their exposure to inflation-protected securities by investing in Vanguard Short-Term Inflation-Protected Securities Index Fund rather than Vanguard Inflation-Protected Securities Fund.

• The Target Retirement Income and Target Retirement 2010 Funds will no longer invest a portion of their assets in Vanguard Prime Money Market Fund.

Although these changes will modify the mix of each Fund’s fixed income investments, they will not affect a Fund’s total fixed income exposure.

The Funds are expected to implement these changes in the coming months.
