The Dow Jones-AIG Commodity Index is composed of 19 futures contracts on physical commodities and was introduced in 1999. The DJ-AIGCI family of indexes includes nine sector sub-indexes, multiple forward month indexes; sub-indexes for each individual commodity in the original DJ-AIGCI as well as for cocoa, lead, platinum and tin.

Also available are Euro-, Yen-, Swiss Franc-, and British Pound-denominated versions of the Dow Jones-AIG Commodity Index; Dow Jones-AIG Commodity Spot IndexSM; and total return versions of each of the excess return indexes and sub-indexes.

As of the end of the fourth quarter of 2008, an estimated $23 billion tracked the DJ-AIGCI group of indexes.
