The investment seeks to replicate the changes in percentage terms of the price of light, sweet crude oil delivered to Cushing, Oklahoma, as measured by the changes in the average of the prices of 12 futures contracts on crude oil traded on the NYMEX. The fund will consist of the near month contract to expire and the contracts for the following eleven months, for a total of 12 consecutive months' contracts. When calculating the daily movement of the average price of the 12 contracts each contract month will be equally weighted.
