Item 8.01. Other Events.

On August 14, 2009, DB Commodity Services LLC (“DBCS”), the managing owner of PowerShares DB Commodity Index Tracking Fund and DB Commodity Index Tracking Master Fund (the “Master Fund”), was informed by the Commodity Futures Trading Commission (the “CFTC”) that effective October 31, 2009, the CFTC will withdraw the no-action relief with respect to certain positions in CBOT corn and CBOT wheat, previously granted to DBCS by CFTC Letter 06-09 dated May 5, 2006 (the “Revocation”).

Effective October 31, 2009, the Master Fund will be subject to the current limits set by CFTC Regulation 150.2 of 13,500 CBOT corn contracts in any single non-spot month and 5,000 CBOT wheat contracts in any single non-spot month. The Master Fund will also continue to be subject to all-months-combined limits of 22,000 contracts for CBOT corn and 6,500 contracts for CBOT wheat, as well as to applicable spot month limits.

As a result of the Revocation, the Master Fund’s positions in CBOT corn and CBOT wheat will be aggregated for federal speculative position limits purposes with the positions in CBOT corn and CBOT wheat held by the PowerShares DB Agriculture Fund through the DB Agriculture Master Fund, as to which DBCS is also the managing owner. DBCS is revising its relevant procedures as a result of the Revocation.

DBCS intends to continue to conduct the business of PowerShares DB Commodity Index Tracking Fund and DB Commodity Index Tracking Master Fund in the normal course, including honoring timely orders submitted with respect to both creation and redemption baskets.
