Strategy. Principal Investment Strategies: The Fund is an actively managed exchange-traded fund (ETF).

The Fund has adopted a non-fundamental policy that, under normal circumstances, the Fund will invest at least 80% of its net assets (plus any borrowings for investment purposes) in U.S. Treasury securities and ETFs that invest at least 80% of their assets in U.S. Treasury securities. The Adviser seeks to fulfill the Funds investment objective by using two income strategies: (1) an interest income strategy and (2) an income generating option strategy. The Funds investment strategy seeks to produce income that is reflective of current short term interest rates without large swings in the Funds net asset value per share. However, the Fund is not a money market fund and is not intended to have an unchanging net asset value per share. Interest Income Strategy The Fund invests primarily in interest income producing U.S. Treasury securities such as bills, notes, and bonds, and U.S. Treasury Inflation-Protected Securities (TIPS) and fixed income ETFs that invest primarily in U.S. Treasuries. TIPS are securities whose principal amount increases with inflation, as measured by the Consumer Price Index and are designed to protect investors from inflation risk. The Fund targets an average securities portfolio duration of one year or less but does not restrict individual security maturity. Duration is a measure of the price sensitivity of a debt instrument when interest rates change. For example, if a note has a duration of 1 year, a 1% rise in rates would result in a 1% decline in price. The Adviser selects securities to maximize portfolio yield within the current duration target and the Adviser sells securities primarily to adjust portfolio duration. Income Generating Option Strategy To generate additional income, the Fund employs an exchange-traded and over-the-counter (OTC) option spread writing strategy on equity, fixed income, volatility, commodity, and currency ETFs and exchange traded products (ETPs). The Adviser focuses on index-based domestically-traded ETFs, for example, such as those linked to the Bloomberg US Aggregate Bond Index. The Adviser selects fixed income ETFs holding securities of any maturity or credit quality. A call option gives the owner the right, but not the obligation, to buy an ETF at a specified price (strike price) within a specific time period. A put option gives the owner the right, but not the obligation, to sell an ETF at a specified price (strike price) within a specific time period. By selling put and call options in return for the receipt of premiums (the purchase price of an option), the Adviser attempts to increase Fund income as the passage of time decreases the value of the written options. Gains from written option premiums are capital gains, but commonly referred to as income. The option writing strategy is a form of leveraged investing. The Adviser focuses on writing short-term options with less than one-month to maturity because their value erodes faster than long-term options. Call Spread Sub-Strategy When the Adviser believes an ETFs price will decrease, remain unchanged, or only increase slightly it employs a call spread strategy. In a call option spread, the Fund sells (writes) an out of the money (above current market price) call option while also purchasing a further out of the money call option. Put Spread Sub-Strategy When the Adviser believes an ETFs price will increase, remain unchanged, or only decrease slightly it employs a put spread strategy. In a put option spread, the Fund sells (writes) an out of the money (below current market price) put option while also purchasing a further out of the money put option. The Adviser expects the written options to expire worthless, but purchases lower-cost further out of the money options to insulate the Fund from large losses if the written options increase in value. The Adviser expects options to be held to expiration, but may adjust positions following a large (over 10%) price swing in an options reference ETF. When writing options, the Fund is required to post collateral to assure its performance to the option buyer. The Fund will hold cash and cash-like instruments or high-quality short term fixed income securities (collectively, Collateral). The Collateral may consist of (1) U.S. Government securities, such as bills, notes and bonds issued by the U.S. Treasury; (2) money market funds (including affiliated money market ETFs); (3) fixed income ETFs; and/or (4) corporate debt securities, such as commercial paper and other short-term unsecured promissory notes issued by companies that are rated investment grade or of comparable quality. The Adviser considers an unrated security to be of comparable quality to a security rated investment grade if it believes it has a similar low risk of default. Show less
