Additionally, the Fund invests in securities maturing in 397 days or less and maintains a portfolio dollar-weighted average maturity of 60 days or less and a dollar-weighted average life of 120 days or less. Furthermore, the Fund will hold securities that are sufficiently liquid to meet reasonably foreseeable shareholder redemptions and maintain at least 25% of its total assets in daily liquid assets and at least 50% of its total assets in weekly liquid assets. U.S. Government securities are obligations issued or guaranteed as to principal or interest by the U.S. Government, its agencies or instrumentalities. Certain obligations that are issued by U.S. government agencies or instrumentalities (also referred to as government sponsored enterprises or GSEs, which have been created under Congressional charter) are not fully guaranteed by the U.S. Treasury. For example, debt issued by the Federal National Mortgage Association (Fannie Mae), the Federal Home Loan Mortgage Corporation (Freddie Mac) and the Federal Home Loan Banks are not supported by the full faith and credit of the United States. The maturity of certain variable and floating rate instruments is measured by reference to the next interest rate reset date rather than the absolute maturity of the instrument. The Fund may transact in securities on a when-issued, delayed delivery or forward commitment basis. Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in U.S. Government securities. For this purpose, U.S. Government securities are as defined above plus repurchase agreements fully collateralized by U.S. Government securities. This 80% policy is a non-fundamental policy and the Fund will not change it without providing shareholders with at least 60 days prior notice. The Funds Board of Trustees (the Board) has determined that the Fund will qualify as a government money market fund pursuant to Rule 2a-7. Many U.S. government money market instruments pay income that is generally exempt from state and local income tax, although they may be subject to corporate franchise tax in some states. The Fund may invest a significant percentage of its assets in repurchase agreements. Repurchase agreements are transactions in which the Fund purchases government securities and simultaneously commits to resell them to the same counterparty at a future time and at a price reflecting a market rate of interest. The Fund expects to focus initially in overnight repurchase agreements. However, in the future, the Fund may invest in repurchase agreements with longer maturities. Income from repurchase agreements may not be exempt from state and local income taxation. Repurchase agreements often offer a higher yield than investments directly in government securities. Although the Fund will seek to continue to qualify as a government money market fund, it will not seek to maintain a stable net asset value (NAV) per share using the amortized cost or penny rounding method of valuation. Instead, the Fund will calculate its NAV per share based on the market value of its investments. In addition, unlike a traditional money market fund, the Fund operates as an exchange traded fund (ETF). As an ETF, the Funds shares will be traded on the Cboe BZX Exchange, Inc. (the Exchange) and will generally fluctuate in accordance with changes in NAV per share as well as the relative supply of, and demand for, shares on the Exchange. An investment in the Fund is not a bank account and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Funds sponsor is not required to reimburse the Fund for losses, and you should not expect that the sponsor will provide financial support to the Fund at any time, including during periods of market stress. You could lose money by investing in the Fund. The Fund is an actively managed ETF that does not seek to replicate the performance of a specified index. Show less
