Item 8.01. Other Events.

As disclosed in the prospectus of PowerShares DB Multi-Sector Commodity Trust dated May 1, 2009, which includes information regarding the PowerShares DB Energy Fund, DB Energy Master Fund, PowerShares DB Oil Fund and DB Oil Master Fund (collectively, the “Funds”), the Commodity Futures Trading Commission and commodity exchanges impose position limits on market participants trading in certain commodities included in the Deutsche Bank Liquid Commodity Index–Optimum Yield Energy Excess Return™ Index (the “DBE Index”), which includes Light, Sweet Crude Oil (WTI), Heating Oil, Brent Crude Oil, RBOB Gasoline and Natural Gas (the “DBE Index Commodities”) and the Deutsche Bank Liquid Commodity Index–Optimum Yield Crude Oil Excess Return™ Index (the “DBO Index”), which includes only Light, Sweet Crude Oil (WTI) (the “DBO Index Commodity”). The DBE Index and the DBO Index are comprised of futures contracts on the DBE Index Commodities (the “DBE Index Contracts”) and the DBO Index Commodity (the “DBO Index Contracts,” and together with the DBE Index Contracts, the “Index Contracts”) respectively, that expire in a specific month and trade on a specific exchange. Because the Funds have approached position limits with respect to certain of the Index Contracts, the Funds plan to invest in other futures contracts based on the Index Contracts (“Replacement Futures Contracts”) as each Fund surpasses these position limits.

When applicable, the specifications and weights of these Replacement Futures Contracts will be communicated on the Index Weights webpage of each Fund, which may be found at http://dbfunds.db.com/dbe/weights.aspx (with respect to PowerShares DB Energy Fund) and http://dbfunds.db.com/dbo/weights.aspx (with respect to PowerShares DB Oil Fund). These webpages will continue to disclose the Index Weights as it has since inception of the Funds, but will also disclose each Fund’s weights, which will reflect the weights of the underlying futures contracts of each Fund.
