Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Basis of Consolidation The condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended November 30, 2020. The basis of consolidation is unchanged from the disclosure in the Company's Notes to Consolidated Financial Statements section in its Form 10-K for the year ended November 30, 2020. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for the fair presentation of the accompanying condensed consolidated financial statements have been made. The Company has historically experienced, and expects to continue to experience, variability in quarterly results. The condensed consolidated statements of operations for the three months ended February 28, 2021 are not necessarily indicative of the results to be expected for the full year. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Cash and Cash Equivalents Homebuilding cash and cash equivalents as of February 28, 2021 and November 30, 2020 included $752.5 million and $314.3 million, respectively, of cash held in escrow for approximately three days. Share-based Payments During the three months ended February 28, 2021 and February 29, 2020, the Company granted employees 1.4 million and 0.9 million nonvested shares, respectively. Recently Adopted Accounting Pronouncements In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("ASU 2016-13"). ASU 2016-13 significantly changes the impairment model for most financial assets and certain other instruments. ASU 2016-13 requires immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets, which generally results in earlier recognition of allowances for credit losses on loans and other financial instruments. ASU 2016-13 was effective for the Company's fiscal year beginning December 1, 2020. The adoption of ASU 2016-13 did not have a material impact on the Company's condensed consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350), Simplifying the Accounting for Goodwill Impairment ("ASU 2017-04"). ASU 2017-04 removes the requirement to perform a hypothetical purchase price allocation to measure goodwill impairment. A goodwill impairment will now be the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 was effective for the Company’s fiscal year beginning December 1, 2020. The impact of the adoption of ASU 2017-04 did not have a material impact on the Company's consolidated financial statements. New Accounting Pronouncements In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740), Simplifying the Accounting for Income Taxes ("ASU 2019-12"). ASU 2019-12 will be effective for the Company’s fiscal year beginning December 1, 2022. The Company is currently evaluating the impact the adoption of ASU 2019-12 will have on the Company's condensed consolidated financial statements. Reclassifications Certain prior year amounts in the condensed consolidated financial statements have been reclassified to conform with the 2021 presentation. The Company reclassed the balance of its investment in Doma, formerly States Title, to which the Company sold the majority of the Financial Services segment's retail title agency business and title insurance underwriter in the first quarter of 2019, from the Financial Services segment to the Lennar Other segment in the Condensed Consolidated Balance Sheets for all periods presented. This was reclassed to be included in our strategic technology investments as the entity has announced that it will merge with a publicly traded special purpose acquisition company. In addition, the Company reflected its contributions to its charitable foundation in a new line on its Condensed Consolidated Statements of Operations for all periods presented. This was previously reflected in the Corporate general and administrative line. These reclassifications had no impact on the Company's total assets, total equity, revenues or net earnings in its condensed consolidated financial statements.
