How Does USO Operate?

An investment in USO shares provides a means for diversifying an investor’s portfolio or hedging exposure to changes in oil prices. An investment in the shares allows both retail and institutional investors to easily gain this exposure to the crude oil market in a transparent, cost-effective manner.

In providing such exposure, USCF employs a “neutral” investment strategy in order to track changes in the price of the Benchmark Oil Futures Contract regardless of whether the price goes up or goes down. USO’s “neutral” investment strategy is designed to permit investors generally to purchase and sell USO’s shares for the purpose of investing indirectly in crude oil in a cost-effective manner, and/or to permit participants in the oil or other industries to hedge the risk of losses in their crude oil-related transactions. Accordingly, depending on the investment objective of an individual investor, the risks generally associated with investing in crude oil and/or the risks involved in hedging may exist. In addition, an investment in USO involves the risk that the daily changes in the price of USO’s shares, in percentage terms, will not accurately track the daily changes in the Benchmark Oil Futures Contract, in percentage terms, and that daily changes in the Benchmark Oil Futures Contract, in percentage terms, will not closely correlate with daily changes in the spot prices of light, sweet crude oil, in percentage terms.

To meet its investment objective, USO primarily invests in futures contracts for light, sweet crude oil, other types of crude oil, diesel-heating oil, gasoline, natural gas, and other petroleum-based fuels that are traded on the NYMEX, ICE Futures or other U.S. and foreign exchanges (collectively, “Oil Futures Contracts”) and, to a lesser extent, in order to comply with regulatory requirements or in view of market conditions, other oil-related investments such as cash-settled options on Oil Futures Contracts, forward contracts for oil, cleared swap contracts and non-exchange traded over-the-counter (“OTC”) transactions that are based on the price of oil, other petroleum-based fuels, Oil Futures Contracts and indices based on the foregoing (collectively, “Other Oil-Related Investments”). For convenience and unless otherwise specified, Oil Futures Contracts and Other Oil-Related Investments collectively are referred to as “Oil Interests” in this annual report on Form 10-K. USO invests substantially the entire amount of its assets in Oil Interests while supporting such investments by holding the amounts of its margin, collateral and other requirements relating to these obligations in short-term obligations of the United States of two years or less (“Treasuries”), cash and cash equivalents. The daily holdings of USO are available on USO’s website at www.uscfinvestments.com.

Following the significant market volatility that occurred in the Spring of 2020 and the market conditions, regulatory requirements and risk mitigation measures taken by USO and USO’s FCM that impacted USO as a result thereof, USO disclosed its parameters for making decisions regarding the permitted investments USO would hold, including the intended order of priority in selection investments and the type of investments to be held in its portfolio.

Beginning with the monthly roll in September 2023 and ending with the monthly roll in January 2024, USO transitioned its investment portfolio to primarily invest in the Benchmark Oil Futures Contract, consistent with USO’s investment strategy prior to the Spring of 2020. However, USO has had, and will continue to have, the ability to invest in Oil Futures Contracts beyond the Benchmark Oil Futures Contract and Other Oil-Related Investments, such as OTC swaps, and USO may make such investments if market conditions (including but not limited to those allowing USO to obtain greater liquidity (i.e., liquidity requirements) or to execute transactions with more favorable pricing), regulatory requirements (including, but not limited to, exchange accountability levels and position limits imposed by NYMEX as well as statutory or regulatory limits), risk mitigation measures (including those that may be taken by USO, USO’s FCMs, counterparties or other market participants), liquidity requirements, or other factors require USO to do so in order to meet its investment objective. USO may invest in Oil Futures Contracts beyond the Benchmark Oil Futures Contract, and/or Other Oil-Related Investments, as a result or in response to any of the foregoing factors. In addition, USO may need to hold significant portions of its portfolio in cash beyond what it has historically held for reasons including (but not limited to) the need to address the changes in market conditions, regulatory requirements or risk mitigation measures or the need to satisfy potential margin requirements.

Each month over a five-day period, USO changes the Benchmark Oil Futures Contract, which at the beginning of the month is the futures contract on light, sweet crude oil as traded on the NYMEX that is the near or front month to expire (referred to herein as the first month), into the NYMEX futures contract that is the next month contract to expire (referred to herein as the second month). The Benchmark Oil Futures Contract remains the futures contract on light, sweet crude oil as traded on the NYMEX for the first month before the roll period. During the roll period, the Benchmark Oil Futures Contract will proportionately change each day of the roll to the futures contract on light, sweet crude oil as traded on the NYMEX for the second month, until the roll is completed. On each day over a five-day period, USCF “rolls” USO’s positions in Oil Interests by closing, or selling, a percentage of USO’s positions in Oil Interests and reinvesting the proceeds from closing those positions in new Oil Interests that reflected the change in the Benchmark Oil Futures Contract. USO rolls its positions in Oil Futures Contracts in the first month prior to the end of the month to avoid such contracts’ expiration and having to take delivery of the underlying commodity.

Typically, on each day during the five-day roll period, USO intends to rebalance approximately 20% of the announced percentage of the notional value of its nearest month instrument and other specified instruments (which could be 100% of such notional value of such interests) and reinvest the proceeds in the remaining current portfolio holdings as well as further-dated contracts and any new specified portfolio holdings. In addition, USO may need to adjust the roll/rebalance in light of market conditions, regulatory requirements, risk mitigation measures (including those that may be taken by USO, USO’s FCMs, counterparties or other market participants), or other factors that impact the ability of USO to make its investments and achievement its investment objective.

USO will roll its positions during the first 5 trading days of each subsequent month. The anticipated dates that the monthly roll period will commence are posted on USO’s website at www.uscfinvestments.com, and are subject to change without notice.

Prior to January 1 2026, USO rolled its positions over a ten-day period instead of a five-day period. The change from a ten-day roll period to a five-day roll period did not change USO’s benchmark or its investment objective.

USO’s total portfolio composition is disclosed on its website each business day that the NYSE Arca is open for trading. The website disclosure of portfolio holdings is made daily and includes, as applicable, the name and value of each Oil Interest, the specific types of Other Oil-Related Investments and characteristics of such Other Oil-Related Investments, the name and value of each Treasury and cash equivalent, and the amount of cash held in USO’s portfolio. USO’s website is publicly accessible at no charge. USO’s assets used for margin and collateral are held in segregated accounts pursuant to the Commodity Exchange Act (the “CEA”) and CFTC regulations.

Creation and Redemption Baskets.

The shares issued by USO may only be purchased by Authorized Participants and only in blocks of 100,000 shares, called “Creation Baskets”. The amount of the purchase payment for a Creation Basket is equal to the aggregate NAV of the shares in the Creation Basket. Similarly, only Authorized Participants may redeem shares and only in blocks of 100,000 shares, called “Redemption Baskets”. The amount of the redemption proceeds for a Redemption Basket is equal to the aggregate NAV of shares in the Redemption Basket. The purchase price for Creation Baskets and the redemption price for Redemption Baskets are the actual NAV calculated at the end of the business day when a request for a purchase or redemption is received by USO. The NYSE Arca publishes an approximate per share NAV intra-day based on the prior day’s per share NAV and the current price of the Benchmark Oil Futures Contract and Other Oil-Related Investments held by USO, but the price of Creation Baskets and Redemption Baskets is determined based on the actual per share NAV calculated at the end of the day.

While USO issues shares only in Creation Baskets, shares are listed on the NYSE Arca and investors may purchase and sell shares at market prices like any listed security.

What is USO’s Investment Strategy?

In managing USO’s assets, USCF does not use a technical trading system that issues buy and sell orders. USCF instead employs a quantitative methodology whereby each time a Creation Basket is sold, USCF purchases Oil Interests, such as the Benchmark Oil Futures Contract and other Oil Futures Contracts, that have an aggregate market value that approximates the amount of Treasuries and/or cash received upon the issuance of the Creation Basket.

USO intends to continue to pursue its investment objective as described above. By remaining invested as fully as possible in Oil Futures Contracts or Other Oil-Related Investments, USCF believes that the daily changes in percentage terms of USO’s NAV will continue to closely track the daily changes in percentage terms in the price of the Benchmark Oil Futures Contract. USCF believes that certain arbitrage opportunities result in the price of the shares traded on the NYSE Arca on a percentage basis, closely tracking the per share NAV of USO. Additionally, daily changes in the price of the Benchmark Oil Futures Contracts have closely tracked the daily changes in the spot price of light, sweet crude oil. Based on these expected interrelationships, USCF believes that the daily changes in the price of USO’s shares as traded on the NYSE Arca, on a percentage basis, have closely tracked and will continue to closely track the changes in the spot price of light, sweet crude oil on a percentage basis. For performance data relating to USO’s ability to track its benchmark, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Tracking USO’s Benchmark” in this annual report on Form 10-K.

USO seeks to invest in a combination of Oil Interests such that the daily changes in its NAV, measured in percentage terms, will closely track the daily changes in the price of the Benchmark Oil Futures Contract, also measured in percentage terms. As a specific benchmark, USCF endeavors to place USO’s trades in Oil Interests and otherwise manage USO’s investments so that “A” will be within plus/minus ten percent (10%) of “B”, where:
