New Target Indexes

The board of trustees of Vanguard European Stock Index Fund and Vanguard Pacific Stock Index Fund has approved the adoption of new target indexes for the Funds. The board believes that the new indexes, listed below, are well-constructed and offer comprehensive coverage of the Funds’ respective market segments. In addition, Vanguard’s agreement with the new index provider may result in considerable savings to shareholders over time in the form of lower expense ratios.


Vanguard Fund	Current Target Index	New Target Index
European Stock Index	MSCI Europe Index	FTSE Developed Europe
Fund		Index
Pacific Stock Index	MSCI Pacific Index	FTSE Developed Asia
Fund		Pacific Index

The Funds are expected to implement these changes sometime over the coming months. To protect the Funds from the potential for harmful “front running” by traders, the exact timing of the index changes and portfolio transitions will not be disclosed to investors. In the meantime, the Funds will continue seeking to track their current indexes.

Each new index measures the same market segment as the corresponding current index, so the investment objectives and risks described in each Fund’s current prospectus will not change. A Fund’s new target index could provide different investment returns (either lower or higher) or different levels of volatility than its existing index over any period of time.

(over, please)

The adjustments to each Fund’s portfolio holdings are expected to result in modest, temporary increases in the Fund’s transaction costs and turnover rate. The transition also may cause each Fund to realize taxable capital gains, although the board of trustees believes that any gains realized are likely to be offset by accumulated tax losses. It is important to note that the actual transaction costs, turnover rate, and capital gains will be highly dependent upon a number of factors, including the market environment at the time of the portfolio adjustments.

Additional information about the new target indexes is available on vanguard.com.

Name Changes for ETF Shares

To better coincide with the new target indexes, the ETF share class of each Fund will change its name as listed below. The name changes will occur at the same time that the index changes become effective.
