The Fund seeks to track the price and yield performance, before fees and expenses of an index that provides exposure to futures contracts on a diversified basket of commodities indices. In order to achieve this objective, the Fund will gain indirect exposure to the individual constituents of the Optimised Roll Commodity Total Return Index (the “Index”) in the same weighting as the Index through the use of swaps which provides the Fund with the performance of the Index (the “Swap”). As a result, the Fund may have an indirect exposure to the individual constituents of the Index of up to 20% of its Net Asset Value, which limit may be raised to 35% for a single constituent in exceptional market conditions, including (but not limited to) circumstances in which such constituent occupies a dominant market position.
