Why It Matters
This monthly account statement gives investors a timely snapshot of USO’s monthly performance and changes in net asset value (NAV), which helps assess short-term fund behavior and track monthly results. Because the statement is “furnished” rather than “filed,” it may have more limited legal incorporation into future SEC filings—investors should rely on it for current performance detail but consult formal filings for material legal disclosures.
