The Tax-Managed US Marketwide Value Portfolio is a no-load mutual fund designed to capture the returns and diversifications of a broad cross-section of US value companies, on a market cap-weighted basis. The Portfolio invests in securities of US companies whose size (market capitalization) falls within the range of total market capitalization. The available universe is comprised of companies listed on the New York Stock Exchange, American Stock Exchange, or NASDAQ National Market System. Securities are considered value stocks primarily because a company's shares have a high book value in relation to their market value (BtM). This BtM sort excludes firms with negative or zero book values. In assessing value, additional factors such as price to cash flow or price to earning ratios may be considered, as well as economic conditions and developments in the issuer's industry. The criteria for assessing value are subject to change from time to time. The Portfolio seeks to minimize the impact of federal taxes by deferring the realization of net capital gains and attempting to minimize the receipt of dividend income in order to minimize the taxable distributions to investors.

Performance data represents past performance. Past performance is no guarantee of future results, and current performance may be higher or lower than the performance displayed. The investment return and principal value of an investment will fluctuate such that an investor's shares, when redeemed, may be worth more or less than their original cost. Total returns include reinvestment of dividends and capital gains and are net of all fees and expenses. Prior to April 2002, certain international equity portfolios charged a reimbursement fee to the purchasers of shares of those portfolios.

Market Risk
Even a long-term investment approach cannot guarantee a profit. Economic, political, and issuer-specific events will cause the value of securities, and the funds that own them, to rise or fall. Because the value of your investment in a fund will fluctuate, there is a risk that you will lose money.

Small Company Risk
Securities of small firms are often less liquid than those of large companies. As a result, small company stocks may fluctuate relatively more in price.

Tax Management Strategy Risk
Tax-management strategies may alter investment decisions and affect the portfolio holdings when compared to those of non-tax-managed mutual funds. Performance of the fund may deviate from that of non-tax-managed mutual funds.
