Calamos Autocallable Income ETF (the "Fund") seeks to generate high monthly income while providing reduced downside risk through exposure to the MerQube US Large Cap Vol Advantage Autocallable Index. The Fund is a non-diversified, actively managed ETF that, invests in U.S. Treasuries, cash and cash equivalents and unfunded total return swaps that provide exposure to the Autocallable Index. The Index is designed to reflect the collective performance of a theoretical portfolio of 52 to 260 synthetic Autocallables arranged in a laddered structure with staggered entry points with similar fixed parameters. The Fund expects to invest substantially all of its assets in U.S. Treasury securities with remaining maturities of one (1) year or less, cash and cash equivalents and unfunded total return swaps providing exposure to an Index. In order to meet its margin requirements on the Swap Agreements, the Fund may allocate all or a significant portion of its cash to investments in eligible collateral instruments such as: investment-grade fixed income and floating rate bonds; notes with variable interest rates tied to benchmarks issued by governments and European or U.S. investment-grade corporate issuers; commercial paper and money market funds.
