Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of presentation | Basis of presentation The accompanying consolidated interim financial statements were prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Interim financial statements do not include all disclosures provided in annual financial statements and, accordingly, these financial statements should be read in conjunction with those appearing in the 2021 Annual Report. The information is unaudited but includes all adjustments that are, in the opinion of management, necessary for a fair presentation of the accompanying consolidated interim financial statements and are of a normal recurring nature. Depreciation, depletion and amortization expense is reported separately on the Consolidated Statements of Income and therefore is excluded from the other line items within operating expenses. On August 4, 2022, the Company announced its Board of Directors unanimously approved a plan to pursue the separation of Knife River from the Company. The separation is planned as a tax-free spinoff transaction to the Company’s stockholders for U.S. federal income tax purposes. As the next step of the Company’s strategic planning, on November 2, 2022, the board of directors unanimously determined the best way to optimize value would be to create two pure-play companies: a leading construction materials company and a regulated energy delivery company. Accordingly, the board has authorized management to commence a strategic review process for MDU Construction Services with the objective of achieving the board’s goal of creating two pure-play public companies. Discontinued operations include the supporting activities of Fidelity and are shown in income from discontinued operations on the Consolidated Statements of Income. Unless otherwise indicated, the amounts presented in the accompanying notes to the consolidated financial statements relate to the Company's continuing operations. In the fourth quarter of 2021, the Company made changes to the presentation of the Consolidated Statements of Cash Flows to provide further clarity on the sources and uses of net cash provided by operating activities and net cash provided by (used in) financing activities. Certain prior period amounts have been reclassified to conform to the current year presentation. These reclassifications did not impact total net cash provided by operating activities or net cash provided by financing activities for the nine months ended September 30, 2021. Management has also evaluated the impact of events occurring after September 30, 2022, up to the date of the issuance of these consolidated interim financial statements on November 3, 2022, that would require recognition or disclosure in the Consolidated Financial Statements.
