Daily percentage changes in USO’s NAV may not correlate with daily percentage changes in the price of the Benchmark Oil Futures Contract. It is possible that the daily percentage changes in USO’s NAV per share may not closely correlate to daily percentage changes in the price of the Benchmark Oil Futures Contract. Non-correlation may be attributable to disruptions in the market for light, sweet crude oil, the imposition of position or accountability limits by regulators or exchanges, or other extraordinary circumstances. As USO approaches or reaches position limits with respect to the Benchmark Oil Futures Contract and other Oil Futures Contracts or in view of market conditions, USO may begin investing in Other Oil-Related Investments. In addition, USO is not able to replicate exactly the changes in the price of the Benchmark Oil Futures Contract because the total return generated by USO is reduced by expenses and transaction costs, including those incurred in connection with USO’s trading activities, and increased by interest income from USO’s holdings of Treasuries (defined below). Tracking the Benchmark Oil Futures Contract requires trading of USO’s portfolio with a view to tracking the Benchmark Oil Futures Contract over time and is dependent upon the skills of USCF and its trading principals, among other factors.
Daily percentage changes in the price of the Benchmark Oil Futures Contract may not correlate with daily percentage changes in the spot price of light, sweet crude oil. The correlation between changes in prices of the Benchmark Oil Futures Contract and the spot price of crude oil may at times be only approximate. The degree of imperfection of correlation depends upon circumstances such as variations in the speculative oil market, supply of and demand for Oil Futures Contracts (including the Benchmark Oil Futures Contract) and Other Oil-Related Investments, and technical influences in oil futures trading.
