Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Basis of Consolidation The accompanying condensed consolidated financial statements include the accounts of Lennar Corporation and all subsidiaries, partnerships and other entities in which Lennar Corporation has a controlling interest and variable interest entities ("VIEs") (see Note 10 of the Notes to the Condensed Consolidated Financial Statements) in which Lennar Corporation is deemed to be the primary beneficiary (the "Company"). The Company’s investments in both unconsolidated entities in which a significant, but less than controlling, interest is held and in VIEs in which the Company is not deemed to be the primary beneficiary, are accounted for by the equity method. All intercompany transactions and balances have been eliminated in 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, 2019. 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 29, 2020 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 29, 2020 and November 30, 2019 included $502.2 million and $565.8 million, respectively, of cash held in escrow for approximately three days. Share-based Payments During the three months ended February 29, 2020, the Company granted employees 0.9 million nonvested shares. During the three months ended February 28, 2019, the Company granted employees an immaterial number of nonvested shares. Recently Adopted Accounting Pronouncements In March 2016, the FASB issued ASU 2016-02, Leases ("ASU 2016-02"), which provides guidance for accounting for leases. ASU 2016-02 requires lessees to classify leases as either finance or operating leases and to record a right-of-use (“ROU”) asset and a lease liability for all leases with a term greater than 12 months regardless of the lease classification. The lease classification determined whether the lease expense was recognized based on an effective interest rate method or on a straight line basis over the term of the lease. Accounting for lessors remains largely unchanged from current GAAP. ASU 2016-02 was effective for the Company beginning December 1, 2019. The Company elected the available practical expedients on adoption. Additionally, in preparation for adoption of the standard, the Company has implemented internal controls and key system functionality to enable the preparation of financial information. The standard did not have a material impact on our condensed consolidated statements of operations and comprehensive income (loss) or our condensed consolidated statements of cash flows. As a result of the adoption, as of February 29, 2020, the Company has recorded $143.7 million of ROU assets and $150.8 million of lease liabilities on its condensed consolidated balance sheets within other assets and other liabilities of the respective segments.
