The Fund may also invest in cash, cash equivalents, and money market instruments that utilize T-Bills as the underlying securities. REX Advisers, LLC (the Adviser) serves as the investment adviser to the Fund. The Funds investment sub-adviser is Tuttle Capital Management, LLC (the Sub-Adviser). The Sub-Adviser employs a laddered maturity structure whereby the Fund invests in T-Bills with different short-term maturity dates designed to maintain a target dollar-weighted average maturity (WAM) of approximately 60 days. As the T-bills mature, the Fund reinvests the proceeds into new T-bills at current market interest rates, a practice referred to as rolling. This continuous rolling process helps the Fund take advantage of changing interest rates and maintain liquidity as securities mature. The Sub-Adviser actively manages both the Funds laddered positioning and reinvestment timing to optimize yield across the front end of the U.S. Treasury curve. The Sub-Adviser may, in its discretion, extend the portfolios WAM beyond the 60-day target if the Sub-Adviser identifies opportunities for higher returns by holding T-Bills with slightly longer maturities (such as when short-term interest rates are high compared to longer-term rates), when there are disruptions in short-term funding markets or when market expectations for future rate cuts cause slightly longer maturities economically advantageous. Conversely, the Sub-Adviser may reduce the portfolios WAM to 30 days or less to preserve liquidity or reduce the risk from interest rate changes. This Funds laddered maturity and practice of rolling may result in high portfolio turnover for the Fund. The Fund is classified as non-diversified under the Investment Company Act of 1940, as amended (the 1940 Act). Show less
