Item 8.01.

Other Events.

As disclosed in the prospectus of PowerShares DB Commodity Index Tracking Fund (the “Fund”), the Commodity Futures Trading Commission and commodity exchange rules impose speculative position limits on market participants trading in five commodities included in the Deutsche Bank Liquid Commodity Index–Optimum Yield Excess Return™ (the “Index”), namely, light, sweet crude oil, heating oil, gold, corn and wheat (the “Index Commodities”). The Index is comprised of futures contracts on the Index Commodities that expire in a specific month and trade on a specific exchange (the “Index Contracts”). Because the Fund is approaching position limits with respect to certain of the Index Contracts, the Fund plans to invest in other futures contracts based on the Index Commodities (“Replacement Futures Contracts”) when (and if) the 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 the Fund, which may be found at http://www.dbfunds.db.com/dbc/weights.aspx. This webpage will continue to disclose the Index Weights as it has since inception of the Fund, and will also disclose the Fund weights, which will reflect the weights of the underlying futures contracts of the Fund.
