Supplement dated August 15, 2011 to the
GMO Trust Prospectus and Statement of Additional Information (SAI), each dated June 30, 2011
GMO Global Balanced Asset Allocation Fund
The Board of Trustees of GMO Trust has approved changing the name of GMO Global Balanced Asset
Allocation Fund to GMO Global Asset Allocation Fund.
Accordingly, effective September 15, 2011 (the Effective Date), all references to the Funds name as contained in the Prospectus and SAI will be changed to GMO Global Asset Allocation Fund.
In conjunction with the name change, as of the Effective Date, the Fund will no longer be bound
by its policy to invest at least 25% of its assets in fixed income investments and at least 25% of
its assets in equity investments, and the description of the Funds principal investment strategies on page 132 of the Prospectus is
replaced with the following:
Principal investment strategies
The Fund is a fund of funds and invests primarily in shares of other GMO Funds, which may include
the International Equity Funds, the U.S. Equity Funds, the Fixed Income Funds, Alpha Only Fund,
Alternative Asset Opportunity Fund, Debt Opportunities Fund, High Quality Short-Duration Bond Fund,
Special Situations Fund and World Opportunity Overlay Fund (collectively, the underlying Funds)
(see Additional Information About the Funds Investment Strategies, Risks, and Expenses Asset
Allocation Funds). In addition, the Fund may hold securities (particularly asset-backed
securities) directly or through one or more subsidiaries or other entities. The Fund may be exposed
to foreign and U.S. equity investments (which may include emerging country equities, both growth
and value style equities and equities of any market capitalization), U.S. and foreign fixed income
securities (including asset-backed securities and other fixed income securities of any credit
quality and having any maturity or duration), the investment returns of commodities and, from time
to time, other alternative asset classes.
The Manager uses multi-year forecasts of relative value and risk among asset classes (e.g., foreign
equity, U.S. equity, emerging country equity, emerging country debt, U.S. fixed income, foreign
fixed income and commodities) to select the underlying Funds in which the Fund invests and to
decide how much to invest in each. The Manager changes the Funds holdings of underlying Funds in
response to changes in its investment outlook and market valuations and may use redemption/purchase
activity to rebalance the Funds investments. Under normal circumstances, the Manager intends to
invest not more than 85% of the Funds assets in the U.S. Equity and International Equity Funds.
For cash management purposes, the Fund may invest in U.S. Treasury Fund and unaffiliated money
market funds.
