Oil and Natural Gas Reserve and Standardized Measure

The NPI represents a net profit overriding royalty interest in various properties owned by the Operating Partnership. The Royalty Properties consist of producing and nonproducing mineral, royalty, overriding royalty, net profits, and leasehold interests located in 593 counties and parishes in 28 states. Amounts set forth herein attributable to the NPI reflects our 96.97% net share. Although new activity has occurred on certain of the Royalty Properties, based on engineering studies available to date, no events have occurred since December 31, 2023 that would have a material effect on our estimated proved developed reserves.

In accordance with U.S. GAAP and Securities and Exchange Commission rules and regulations, the following information is presented with regard to the Royalty Properties and NPI oil and natural gas reserves, all of which are proved, developed, and located in the United States. These rules require inclusion as a supplement to the basic financial statements a standardized measure of discounted future net cash flows relating to proved oil and natural gas reserves. The standardized measure, in management's opinion, should be examined with caution. The basis for these disclosures are petroleum engineers’ reserve studies which contain estimates of quantities and rates of production of reserves. Revision of prior year estimates can have a significant impact on the results. Changes in production costs may result in significant revisions to previous estimates of proved reserves and their future value. Therefore, the standardized measure is not necessarily a best estimate of the fair value of oil and natural gas properties or of future net cash flows.

The following summaries of changes in reserves and standardized measure of discounted future net cash flows were prepared from estimates of proved reserves. The Standardized Measure of Discounted Future Net Cash Flows reflects adjustments for fuel, shrinkage, and pipeline loss.
