Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation The unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission, or SEC, for Form 10-Q. Certain information and note disclosures normally included in the annual financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are adequate to make the information provided not misleading. Accordingly, these condensed consolidated financial statements and related notes should be read in conjunction with the consolidated financial statements and related notes thereto in the Company's annual report on Form 10-K for fiscal year 2024 as filed with the SEC on March 26, 2025. The condensed consolidated financial statements include the accounts of Artesian Resources Corporation and its wholly-owned subsidiaries, including its principal operating company, Artesian Water. In the opinion of the Company, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments (unless otherwise noted) necessary to present fairly the Company's balance sheet position as of September 30, 2025, the results of its operations for the three and nine-month periods ended September 30, 2025 and September 30, 2024, its cash flows for the nine-month periods ended September 30, 2025 and September 30, 2024 and the changes in stockholders’ equity for the three and nine-month periods ended September 30, 2025 and September 30, 2024. The December 31, 2024 Condensed Consolidated Balance Sheet was derived from the Company’s December 31, 2024 audited consolidated financial statements but does not include all disclosures and notes normally provided in annual financial statements. The results of operations for the interim periods presented are not necessarily indicative of the results for the full year or for future periods.
Regulated Utility Accounting | Regulated Utility Accounting The accounting records of Artesian Water, Artesian Wastewater, and TESI are maintained in accordance with the uniform system of accounts as prescribed by the Delaware Public Service Commission, or the DEPSC. The accounting records of Artesian Water Pennsylvania are maintained in accordance with the uniform system of accounts as prescribed by the Pennsylvania Public Utility Commission, or the PAPUC. The accounting records of Artesian Water Maryland, and Artesian Wastewater Maryland, are maintained in accordance with the uniform system of accounts as prescribed by the Maryland Public Service Commission, or the MDPSC. All these subsidiaries follow the provisions of Accounting Standards Codification, or ASC, 980, Regulated Operations, which provides guidance for companies in regulated industries. These regulated subsidiaries account for the majority of our operating revenue. See Note 16 – Business Segment Information to our Condensed Consolidated Financial Statements for a full description of our segment information.
Use of Estimates | Use of Estimates The condensed consolidated financial statements were prepared in conformity with generally accepted accounting principles in the U.S., which require management to make certain estimates and assumptions that could impact the Company’s financial condition, results of operations and cash flows. Actual results could differ from management's estimates. Management makes certain estimates and assumptions regarding unbilled revenues, accounting for income taxes, credit losses and reserves for bad debt, lease agreements, goodwill and contingent assets and liabilities at the date of the condensed consolidated financial statements.
Utility Plant | Utility Plant All additions to utility plant are recorded at cost. Business combinations pursuant to ASC 805, Business Combinations, may result in a purchase price allocation and the acquired assets are required to be evaluated by the applicable regulatory agency.
Depreciation and Amortization | Depreciation and Amortization For financial reporting purposes, depreciation is recorded using the straight-line method at rates based on estimated economic useful lives, which range from 5 to 85 years. Composite depreciation rates for water utility plant were 1.92%, and 1.93% for September 30, 2025 and December 31, 2024, respectively. In a rate order issued by the DEPSC, the Company was directed, effective June 12, 2024, to begin using revised depreciation rates for utility plant in Artesian Water, which are based on the estimated useful life years. Artesian Water offsets depreciation recorded on utility plant by depreciation on utility property funded by Contributions in Aid of Construction, or CIAC, and Advances for Construction, or Advances. This reduction in depreciation expense is also netted against outstanding CIAC and Advances on the Condensed Consolidated Balance Sheet. Regulatory assets are amortized using the straight-line method over future periods, which range from 5 to 80 years.
