Other Events.

DB Commodity Services LLC, the managing owner (the “Managing Owner”) of PowerShares DB US Dollar Index Trust (the “Trust”), PowerShares DB US Dollar Index Bullish Fund and PowerShares DB US Dollar Index Bearish Fund (each a “Fund” and collectively, the “Funds”), DB US Dollar Index Master Trust (the “Master Trust”), and DB US Dollar Index Bullish Master Fund and DB US Dollar Index Bearish Master Fund (each a “Master Fund” and collectively, the “Master Funds”), has determined that distributions will not be made to the shareholders of the Funds for the calendar year ending December 31, 2010.

As disclosed in the Funds’ prospectus, each Fund makes distributions at the discretion of the Managing Owner. To the extent that a Master Fund’s actual and projected interest income from their holdings of United States Treasury securities and other high credit quality short-term fixed income securities exceeded the actual and projected fees and expenses of such Master Fund and corresponding Fund, the Managing Owner has periodically made distributions of a substantial portion of the estimated amount of such excess. In the current interest rate environment, each Master Fund’s interest income has not exceeded the fees and expenses of such Master Fund and corresponding Fund; therefore, the Managing Owner has determined not to make distributions for the calendar year ending December 31, 2010.
