DB Commodity Services LLC, the managing owner (the “Managing Owner”) of PowerShares DB Multi-Sector Commodity Trust (the “Trust”), PowerShares DB Energy Fund, PowerShares DB Oil Fund, PowerShares DB Precious Metals Fund, PowerShares DB Gold Fund, PowerShares DB Silver Fund, PowerShares DB Base Metals Fund and PowerShares DB Agriculture Fund (each a “Fund” and collectively, the “Funds”), has determined that distributions will not be made to the shareholders of the Funds for the calendar year ending December 31, 2013.

As disclosed in each Fund’s applicable prospectus, each Fund makes distributions at the discretion of the Managing Owner. To the extent that a Fund’s actual and projected interest income from its 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 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 Fund’s interest income has not exceeded the fees and expenses of such Fund; therefore, the Managing Owner has determined not to make distributions for the calendar year ending December 31, 2013.

SIGNATURES

Pursuant to the requirements of the Securities Exchange Act of 1934, each registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
