The investment seeks to provide a duration that is the inverse of its benchmark. The fund will seek to pursue its investment objective primarily by engaging in short sales of U.S. Treasury securities and by investing in derivative instruments that provide returns that are inverse to those available by investing directly in U.S. Treasury securities. Derivative instruments that the fund may invest in include, but are not limited to, futures (including U.S. Treasury futures), options, forward contracts and/or swaps, including interest rate swaps, swaptions and total return swaps.
