In seeking to track the performance of the FTSE US Treasury Bill 3-12 Months Index (the Index), the Fund utilizes a sampling approach, meaning it is not required to buy each security included in the Index. Instead, the Fund may invest in a portion of the Index securities in an effort to maintain a portfolio that, in the aggregate, has generally similar risk and return characteristics to the Index. The number of securities held by the Fund will depend on a number of factors, including the Fund's net asset size relative to the number of Index constituents, the liquidity or prices of Index securities, and transaction costs. The Fund's investment adviser may invest the Fund's assets in a subset of the Index securities or may invest in substantially all of the securities comprising the Index in approximately the same proportions as the Index, as the Adviser determines is in the best interests of the Fund in pursuing its objective.
