Basis of Presentation [Abstract] |
Basis of Accounting [Text Block] | The accompanying Unaudited Condensed Consolidated Financial Statements (the “financial statements”) of M/I Homes, Inc. and its subsidiaries (the “Company”) and notes thereto have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial information. The financial statements include the accounts of the Company. All intercompany transactions have been eliminated. Results for the interim period are not necessarily indicative of results for a full year. In the opinion of management, the accompanying financial statements reflect all adjustments (all of which are normal and recurring in nature) necessary for a fair presentation of financial results for the interim periods presented. These financial statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 (the “2021 Form 10-K”). The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during that period. Actual results could differ from these estimates and have a significant impact on the financial condition and results of operations and cash flows. With regard to the Company, estimates and assumptions are inherent in calculations relating to valuation of inventory and investment in unconsolidated joint ventures, property and equipment depreciation, valuation of derivative financial instruments, accounts payable on inventory, accruals for costs to complete inventory, accruals for warranty claims, accruals for self-insured general liability claims, litigation, accruals for health care and workers’ compensation, accruals for guaranteed or indemnified loans, stock-based compensation expense, income taxes, and contingencies. Items that could have a significant impact on these estimates and assumptions include the risks and uncertainties listed in “Item 1A. Risk Factors” in Part I of our 2021 Form 10-K, as the same may be updated from time to time in our subsequent filings with the SEC. Recently Adopted Accounting Standards In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). ASU 2020-04 is intended to provide temporary optional expedients and exceptions to the US GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. This guidance became effective on March 12, 2020 and can be applied prospectively through December 31, 2022. In January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848): Scope (“ASU 2021-01”), which clarified the scope and application of the original guidance. We fully adopted ASU 2020-04 and ASU 2021-01 in October 2022 after we amended our $90 million mortgage repurchase agreement, dated October 30, 2017, as amended (the “MIF Mortgage Repurchase Facility”), which discontinued the use of LIBOR and replaced it with the One-Month Term SOFR (“SOFR”) rate. The adoption of this guidance did not have a material impact on our consolidated financial statements and disclosures. Significant Accounting Policies There have been no significant changes to our significant accounting policies during the quarter ended September 30, 2022 as compared to those disclosed in our 2021 Form 10-K.
