Fund Investment Overview

(2) Fund Investment Overview

The Fund establishes short 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 Short US Dollar Index (USDX®) Futures Index – Excess Return, the "Short 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 and other high credit quality short-term fixed income securities over the expenses of the Fund. The Index is calculated to reflect the changes in market value over time, whether positive or negative, in short positions on 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.

The Fund does not employ leverage. As of September 30, 2011 and December 31, 2010, the Fund had $125,424,435 (or 100%) and $151,574,112 (or 100%), respectively, of its holdings of cash, United States Treasury Obligations and unrealized appreciation/depreciation on futures contracts on deposit with its Commodity Broker. Of this, $3,212,881 (or 2.56%) and $3,183,089 (or 2.10%), respectively, of the Fund's holdings of cash and United States Treasury Obligations are required to be deposited as margin in support of the Fund's short futures positions on DX Contracts. For additional information, please see the unaudited Schedule of Investments as of September 30, 2011 and the audited Schedule of Investments as of December 31, 2010 for details of the Fund's portfolio holdings.
