The United States Oil Fund LP is an exchange-traded security designed to track the daily price movements of West Texas Intermediate (WTI) light, sweet crude oil. USO issues shares that may be purchased and sold on the NYSE Arca. The investment objective of USO is for the daily changes in percentage terms of its shares' NAV to reflect the daily changes in percentage terms of the spot price of light, sweet crude oil delivered to Cushing, Oklahoma, as measured by the daily changes in price of USO's Benchmark Oil Futures Contract, less USO's expenses. USO's Benchmark is the near month crude oil futures contract traded on the NYMEX. If the near month futures contract is within two weeks of expiration, the Benchmark will be the next month contract to expire. The crude oil contract is WTI light, sweet crude oil delivered to Cushing, Oklahoma.
