The Fund seeks to track the investment results of the ICE BofA Commodity Enhanced Carry Total Return Index (the Underlying Index), which measures the performance of the 10 commodity futures contracts representing the underlying commodities with the largest global production value, where more weight in the Underlying Index is given to those contracts having the highest degree of backwardation or lowest degree of contango (i.e., those with the highest positive carry, as explained below) among a universe of 22 futures contracts on physical agricultural, energy, precious metals, and industrial metals commodities listed on U.S. and non-U.S. futures exchanges, as determined by ICE Data Services, LLC (IDI or the Index Provider). The Underlying Index is rebalanced on a monthly basis and could contain more than 10 contracts during the rebalancing period. The Fund seeks to achieve its investment objective primarily by investing in a total return swap on the Underlying Index.
