NEW YORK, Aug. 13, 2008 — Dow Jones Indexes announced the new target weightings for the Dow Jones-AIG Commodity Index(sm) that will become effective in early January 2009. The new target weights for the commodity components, which were determined and approved by the Dow Jones-AIG Commodity Index Supervisory Committee in August 2008 following consultation with the Dow Jones-AIG Commodity Index Advisory Committee, are listed below.

These weights will be used to determine the Dow Jones-AIG Commodity Index Multipliers for 2009 in January 2009. These multipliers, computed once a year, are factors used to express the percentage weights in U.S. dollar-denominated terms when calculating the Index.

Launched in 1998, the Dow Jones-AIG Commodity index family includes nine sector sub-indexes, multiple forward month indexes, indexes for each individual commodity in the original DJ-AIGCI, Euro-, Yen-, Sterling-, and Swiss Franc-denominated versions of the Dow Jones-AIG Commodity Index, and the Dow Jones-AIG Commodity Spot Index. Also available are total return versions of each of the excess return indexes and sub-indexes. As of the end of the second quarter of 2008, an estimated $55 billion tracked the DJ-AIGCI group of indexes.
