 five years, unless the specific circumstances justify a longer time. All of Magnolia’s proved undeveloped reserves as of December 31, 2024, that are included in this Annual Report, are planned to be developed within one year.

Despite the inherent imprecision in these engineering estimates, Magnolia’s reserves are used throughout the Company’s financial statements. For example, since Magnolia uses the unit-of-production method to amortize its oil and natural gas properties, the quantity of reserves could significantly impact Magnolia’s DD&A expense. A material adverse change in the estimated volumes of reserves could result in property impairments. Finally, these reserves are the basis for Magnolia’s supplemental oil and natural gas disclosures.

Reserves are calculated using an unweighted arithmetic average of commodity prices in effect on the first day of each of the previous 12 months, held flat for the life of the production, except where prices are defined by contractual arrangements. These historical prices often do not approximate the average price that the Company expects to receive for its oil and natural gas production in the future. Operating costs, production and ad valorem taxes, and future development costs are based on current costs with no escalation. Actual costs may be materially higher or lower than the costs utilized in the estimate.

Magnolia has elected not to disclose probable and possible reserves in this filing.

Long-lived Asset Impairments

Long-lived assets used in operations are assessed for impairment whenever changes in facts and circumstances indicate a possible significant deterioration in future cash flows expected to be generated by an asset group. Individual assets are grouped for impairment purposes based on a judgmental assessment of the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets. If there is an indication that the carrying amount of an asset may not be recovered, the asset is assessed by management through an established process in which changes to significant assumptions such as prices, volumes, and future development plans are reviewed. If, upon review, the sum of the undiscounted pre-tax cash flows is less than the carrying value of the asset group, the carrying value is written down to estimated fair value. Because there usually is a lack of quoted market prices for long-lived assets, the fair value of impaired assets is assessed by management using the income approach.

Under the income approach, the fair value of each asset group is estimated based on the present value of expected future cash flows. The income approach is dependent on a number of factors including estimates of forecasted revenue and operating costs, proved reserves, the
