The Fund is an actively managed ETF that seeks to achieve its investment objective by investing primarily in low-duration, high-quality fixed income securities, including collateralized loan obligations (“CLOs”), U.S. Treasury securities, repurchase agreements, reverse repurchase agreements, and other investment grade instruments (collectively, “Fixed Income Securities”). The Fund may also invest in other fixed income securities that are backed (implicitly or explicitly) by the full faith and credit of the U.S. government or the governments of other developed countries, as well as other cash management investment techniques that may involve the use of derivatives for hedging purposes. Through dynamic allocation, the Fund seeks to deliver consistent income with low volatility while maintaining a focus on capital preservation. GMO normally seeks to maintain an estimated interest rate duration of one year or less for the Fund’s portfolio, though individual securities in the portfolio may have a maturity date greater than one year.

Under the repurchase agreements entered into by the Fund, the Fund purchases a security backed by the full faith and credit of the U.S. government from a seller who simultaneously commits to repurchase, on an agreed date, the security from the Fund at the original purchase price plus an agreed upon amount representing interest. Under reverse repurchase agreements, the Fund sells a security backed by the full faith and credit of the U.S. government to a buyer and simultaneously commits to repurchase, on an agreed date, the security from the buyer at the original purchase price plus an agreed upon amount representing interest.

In selecting securities for the Fund’s portfolio, GMO focuses primarily on the relative attractiveness of different obligations (such as bonds, notes or bills), which can vary depending on the general level of interest rates as well as supply and demand imbalances and other market conditions. The factors GMO considers and investment methods GMO uses can change over time.

The Fund also may invest in the GMO U.S. Treasury Fund, a mutual fund advised by GMO, in money market funds unaffiliated with GMO, and directly in the types of investments typically held by money market funds.
