5. Segment Information

The Fund’s operations are managed through a single operating segment. As such, the Fund has only a single reportable segment that derives its revenue from the sale of oil and gas. The Fund’s chief operating decision-maker is the Executive Vice President, Chief Financial Officer and Assistant Secretary of the Fund, who reviews the Fund’s operating results to make decisions about allocating resources and assessing performance for the Fund. The profit or loss metric used to evaluate segment performance is net income; consistent with net income reported on the statement of operations.

The measure of segment assets is reported on the balance sheet as total assets.

The following table is a summary of segment information for the three months ended March 31, 2026 and 2025.
