The investment objective of USOF is for changes in percentage terms of the units’ net asset value to reflect the changes in percentage terms of the spot price of West Texas Intermediate (“WTI”) light, sweet crude oil delivered to Cushing, Oklahoma (“WTI light, sweet crude oil”), less USOF’s expenses. There is no assurance that USO will meet its investment objective"
