USL Tracks This Index: Light, sweet crude oil delivered to Cushing, Oklahoma
Description: The investment objective of USL is to have the changes in percentage terms of the units' net asset value reflect the changes in percentage terms of the price of light, sweet crude oil, as measured by the changes in the average of the prices of 12 futures contracts on crude oil traded on the New York Mercantile Exchange, consisting of the near month contract to expire and the contracts for the following eleven months, for a total of 12 consecutive months' contracts, except when the near month contract is within two weeks of expiration, in which case it will be measured by the futures contracts that are the next month contract to expire and the contracts for the following eleven consecutive months, less USL's expenses.
