Item 8.01. Other Events.

On January 26, 2007, DB Commodity Services LLC, the managing owner of each of PowerShares DB Commodity Index Tracking Fund (the “Fund”) and DB Commodity Index Tracking Master Fund (the “Master Fund”) filed a Prospectus Supplement dated January 26, 2007 (the “Prospectus Supplement”) to the Prospectus dated August 14, 2006 (the “Prospectus”) relating to the Fund and the Master Fund.

The Prospectus Supplement provides, in part, as follows:

“The last paragraph under the sub-heading “Tax-Exempt Organizations” on page 81 of the Prospectus is hereby deleted and replaced, in its entirety, by the following:

‘All of the income realized by the Master Fund is expected to be short-term or long-term capital gain income, interest income or other passive investment income of the type specifically exempt from UBTI as discussed above. Neither the Fund nor the Master Fund will borrow funds for the purpose of acquiring or holding any investments or otherwise incur “acquisition indebtedness” with respect to such investments. Therefore, a tax-exempt entity purchasing Shares would not incur any UBTI by reason of its investment in the Shares or upon sale of such Shares provided that such tax-exempt entity does not borrow funds for the purpose of investing in the Shares.’”

The Prospectus Supplement also updates certain other performance information and Index closing levels as set forth in the Prospectus through December 31, 2006 in accordance with CFTC regulations.
