Summary of Significant Events and Accounting Policies |
Principles of Consolidation and Reporting | Principles of Consolidation and Reporting. The unaudited condensed consolidated financial statements include the accounts of Evolution Petroleum Corporation and its wholly-owned subsidiaries (the “Company”). All significant intercompany transactions have been eliminated in consolidation. The unaudited condensed consolidated financial statements for the previous year may include certain reclassifications to conform to the current presentation. To conform with the current year presentation, “Other receivables” disclosed in Footnote 13, “Additional Financial Statement Information” is included with “Prepaids expenses and other current assets” instead of “Receivables from crude oil, natural gas, and natural gas liquids sales” at June 30, 2022 on the unaudited condensed consolidated balance sheets. This reclassification has no impact on previously reported net income or stockholders’ equity.
Risk and Uncertainties | Risk and Uncertainties. The Company’s oil and natural gas interests are operated by third-party operators and involve other third-party working interest owners. As a result, the Company has limited ability to influence the operation or future development of such properties. However, the Company is proactive with its third-party operators to review spending and present alternative plans.
Use of Estimates | Use of Estimates. The preparation of the Company’s unaudited condensed consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities, if any, at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the respective reporting periods. Significant estimates include (a) reserve quantities and estimated future cash flows associated with proved reserves, which may significantly impact depletion expense and potential impairments of oil and natural gas properties, (b) asset retirement obligations, (c) stock-based compensation, (d) fair values of derivative contract assets and liabilities, (e) income taxes and the valuation of deferred income tax assets, (f) commitments and contingencies, and (g) accruals of crude oil, natural gas, and natural gas liquids (“NGL”) revenues and expenses. The Company analyzes estimates and judgements based on historical experience and various other assumptions and information that are believed to be reasonable. Estimates and assumptions about future events and their effects cannot be predicted with certainty and, accordingly, these estimates may change as additional information is obtained, as new events occur, and as the Company’s environment changes. Actual results may differ from the estimates and assumptions used in the preparation of the Company’s unaudited condensed consolidated financial statements.
Correction of Immaterial Error | Correction of Immaterial Error During the year ended June 30, 2022, the Company identified an issue related to its historical process of calculating the Company’s earnings (loss) per common share (“EPS”). The Company grants restricted stock awards which entitle the recipient to all of the rights of a shareholder of the Company including non-forfeitable rights to receive all dividends or other distributions paid with respect to such shares. Unvested restricted stock is forfeitable until earned and therefore not considered outstanding for basic EPS. Because restricted stock awards have the non-forfeitable right to share in dividends and earnings with common shareholders prior to vesting, the Company must apply the two-class method of allocating distributed and undistributed earnings to unvested restricted stock and outstanding common shares. Historically, it was identified by management that the Company had not been applying the two-class method of calculating basic and diluted EPS in accordance with Accounting Standards Codification (“ASC”) 260, Earnings Per Share (“ASC 260”). Rather, the Company was considering all restricted stock grants as outstanding at the time of issuance in the calculation of EPS. At March 31, 2022, the Company determined that its unvested restricted stock awards were participating securities which contain non-forfeitable rights to dividends. As a result, the Company was required to adjust “Net income (loss) attributable to common stockholders” on the unaudited condensed consolidated statements of operations to allocate dividends paid to unvested shares as well as undistributed earnings. In addition, the Company determined that its basic and diluted weighted average shares outstanding were not adjusted correctly to reflect these participating securities. The Company concluded the adjustments were immaterial to its 2022 interim financial statements in accordance with the guidance in SEC Staff Accounting Bulletin (“SAB”) No. 99, Materiality and SAB No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in the Current Year Financial Statements. The correction resulted in a decrease of $0.01 per basic and diluted share for the three months ended September 30, 2021. See Note 12, “Earnings (Loss) per Common Share” for more details. The Company noted the following adjustments to its EPS presentation for the three months ended September 30, 2021 (in thousands, except per share amounts):

Recently Adopted and Issued Accounting Pronouncements | ​ Recently Issued Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (“ASU 2016-13”). ASU 2016-13 changes the impairment model for most financial assets and certain other instruments, including trade and other receivables, and requires the use of a new forward-looking expected loss model that will result in the earlier recognition of allowances for losses. Early adoption is permitted and entities must adopt the amendment using a modified retrospective approach to the first reporting period in which the guidance is effective. For smaller reporting companies, as provided by ASU 2019-10, Financial Instruments - Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842), ASU 2016-13 is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2022. The Company is currently evaluating the impact of ASU 2016-13 but does not expect that it will have a material effect on the Company’s financial position, results of operations, cash flows or disclosures. Other accounting pronouncements that have recently been issued by the FASB or other standards-setting bodies are not expected to have a material impact on the Company’s financial position, results of operations, cash flows or disclosures.
