Strategy Narrative [Text Block]	GMO seeks to achieve the Fund’s investment objective by investing the Fund’s assets primarily in equities of companies that GMO believes to be of high quality. GMO believes a high quality company generally to be a company that has an established business that will deliver a high level of return on past investments and that will use cash flows to make investments with the potential for a high return on capital or to return cash to shareholders through dividends or share buybacks. In selecting securities for the Fund, GMO uses a combination of investment methods, typically considering both (1) systematic factors, based on profitability, profit stability, leverage, and other publicly available financial information, and (2) judgmental factors, based on GMO’s assessment of future profitability, capital allocation, growth opportunities, and sustainability against competitive forces. GMO also may rely on valuation methodologies, such as discounted cash flow analysis and multiples of price to earnings, revenues, book values or other fundamental metrics. The Fund also is permitted to invest directly and indirectly (e.g., through underlying funds or derivatives) in equities of companies tied economically to any country in the world, including emerging countries.At times, the Fund may have substantial exposure to a single asset class, industry, sector, country, region, issuer, or currency and companies with similar market capitalizations. The Fund may invest in securities of companies of any market capitalization. The factors GMO considers and investment methods GMO uses can change over time. GMO does not manage the Fund to, or control the Fund’s risk relative to, any securities index or securities benchmark.As an alternative to investing directly in equities, the Fund may invest in exchange-traded and over-the-counter (OTC) derivatives and exchange-traded funds (ETFs). The Fund also may invest in derivatives and ETFs in an attempt to obtain or adjust elements of its long or short investment exposure. Derivatives used may include futures, options, forward currency contracts, and swap contracts. In addition, the Fund may lend its portfolio securities.The Fund also may invest in U.S. Treasury Fund, in money market funds unaffiliated with GMO, and directly in the types of investments typically held by money market funds.
