Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation | The accompanying unaudited, consolidated financial statements include the accounts of D.R. Horton, Inc. and all of its 100% owned, majority-owned and controlled subsidiaries, which are collectively referred to as the Company, unless the context otherwise requires. Noncontrolling interests represent the proportionate equity interests in consolidated entities that are not 100% owned by the Company. As of December 31, 2021, the Company owns a 63% controlling interest in Forestar Group Inc. (Forestar) and therefore is required to consolidate 100% of Forestar within its consolidated financial statements, and the 37% interest the Company does not own is accounted for as noncontrolling interests. All intercompany accounts, transactions and balances have been eliminated in consolidation. The financial statements have been prepared in accordance with U.S. Generally Accepted Accounting Principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, these financial statements reflect all adjustments considered necessary to fairly state the results for the interim periods shown, including normal recurring accruals and other items. These financial statements, including the consolidated balance sheet as of September 30, 2021, which was derived from audited financial statements, do not include all of the information and notes required by GAAP for complete financial statements and should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s annual report on Form 10-K for the fiscal year ended September 30, 2021.
Reclassifications | Reclassifications During the fourth quarter of fiscal 2021, the Company changed its internal organization and reporting of its operating segments and reportable segments to combine its single-family rental operations and its multi-family rental operations into a new reporting segment and realigned the aggregation of its homebuilding operating segments into six new reportable segments to better allocate its homebuilding operating segments across geographic reporting regions. The prior year presentation of the Company’s segment information in Note B and in Management’s Discussion and Analysis of Financial Condition and Results of Operations has been conformed to the current presentation for all periods presented.
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates.
Recent Accounting Pronouncements | Pending Accounting Standards In March 2020, the Financial Accounting Standards Board (FASB) issued ASU 2020-04, “Reference Rate Reform,” which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by the discontinuation of the London Interbank Offered Rate (LIBOR) or by another reference rate expected to be discontinued. The guidance was effective beginning March 12, 2020 and can be applied prospectively through December 31, 2022. In January 2021, the FASB issued ASU 2021-01, “Reference Rate Reform - Scope,” which clarified the scope and application of the original guidance. The Company will adopt these standards when LIBOR is discontinued and does not expect them to have a material impact on its consolidated financial statements or related disclosures. In October 2021, the FASB issued ASU 2021-08, which requires application of ASC 606, “Revenue from Contracts with Customers,” to recognize and measure contract assets and liabilities from contracts with customers acquired in a business combination. ASU 2021-08 creates an exception to the general recognition and measurement principle in ASC 805 and will result in recognition of contract assets and contract liabilities consistent with those recorded by the acquiree immediately before the acquisition date. The guidance is effective for the Company beginning October 1, 2023 and interim periods therein, with early adoption permitted. The Company is currently evaluating the impact of this guidance, and it is not expected to have a material impact on its consolidated financial position, results of operations or cash flows.
