Fund Investment Overview

(3) Fund Investment Overview

The Fund establishes long positions in certain futures contracts (the “DX Contracts”), with a view to tracking the changes, whether positive or negative, in the level of the Deutsche Bank Long US Dollar Index (USDX^®) Futures Index–Excess Return (the “Long Index” or the “Index”), over time. The performance of the Fund also is intended to reflect the excess, if any, of its interest income from its holdings of United States Treasury Obligations (“Treasury Income”) and dividends from its holdings in money market mutual funds (affiliated or otherwise) (“Money Market Income”) over the expenses of the Fund. For the avoidance of doubt, the Fund may hold United States Treasury Obligations and money market mutual funds (affiliated or otherwise) for margin and/or cash management purposes.

The Index is calculated to reflect the changes in market value over time, whether positive or negative, of long positions in DX Contracts. DX Contracts are traded through the currency markets of ICE Futures U.S. (formerly known as the New York Board of Trade^®), under the symbol “DX.” The changes in market value over time, whether positive or negative, of the DX Contracts are related to the changes, whether positive or negative, in the level of the U.S. Dollar Index^® (the “USDX^®”). The Index provides a general indication of the international value of the U.S. dollar relative to the six major world currencies (each an “Index Currency,” and collectively, the “Index Currencies”), which comprise the USDX^®–Euro, Japanese Yen, British Pound, Canadian Dollar, Swedish Krona and Swiss Franc.
