Special Dow Jones – AIG Commodity Index<SUP>SM</SUP> Composition Adjustment Announcement – Unleaded Gasoline

The Oversight Committee of the Dow Jones – AIG Commodity Index^SM (“DJ-AIGCI^SM”), following a special meeting today, announced an upcoming change to the designated contract for unleaded gasoline for purposes of calculating the Index and related subindices.

The new designated contract will be the Reformulated Gasoline Blendstock for Oxygen Blending (“RB”) futures contract (Reuters ticker RB, Bloomberg ticker XB), traded on the New York Mercantile Exchange (“NYMEX”), which will replace the New York Harbor Unleaded Gasoline (“HU”) futures contract (Reuters ticker HU, Bloomberg ticker HU), also traded on the NYMEX. The shift from the HU futures contract into the RB futures contract is scheduled to occur during the regularly scheduled roll of futures contracts comprising the Index and related subindices in the April 2006 roll period pursuant to the DJ-AIGCI Handbook.

For the purposes of calculating DJ-AIGCI values, the RB contract will be treated as a continuation of the HU futures series which has been used in calculating the DJ-AIGCI from inception. The July 2006 contract will be the first RB future included in the calculation of the DJ-AIGCI, and the May 2006 contract will be the last HU future included in the calculation of the DJ-AIGCI. No changes to the commodity index multipliers will occur as a result of this change in the designated contract for unleaded gasoline.
