Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation | Basis of Presentation The accompanying unaudited, condensed consolidated financial statements include the accounts of NVR, Inc. (“NVR”, the “Company”, "we", "us" or "our") and its subsidiaries and certain other entities in which the Company is deemed to be the primary beneficiary (see Notes 2 and 3 to the accompanying condensed consolidated financial statements). Intercompany accounts and transactions have been eliminated in consolidation. The statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. Because the accompanying condensed consolidated financial statements do not include all of the information and footnotes required by GAAP, they should be read in conjunction with the financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2019. In the opinion of management, all adjustments (consisting only of normal recurring accruals except as otherwise noted herein) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.
Revenue from Contract with Customer | Revenue RecognitionHomebuilding revenue is recognized on the settlement date at the contract sales price, when control is transferred to our customers.
Recently Adopted Accounting Pronouncements | Recently Adopted Accounting Pronouncements Effective January 1, 2020, we adopted Accounting Standards Update ("ASU") 2016-13, Financial Instruments - Credit Losses (Topic 326), which changed the impairment recognition of financial assets from an as incurred recognition methodology to requiring immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets. Our adoption of this standard did not have a material effect on our consolidated financial statements and related disclosures. Effective January 1, 2020, we adopted ASU 2017-04, Intangibles – Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment. Under the standard, an impairment charge to goodwill is recorded in the amount that the carrying amount of a reporting unit's goodwill exceeds its fair value, not to exceed the amount of goodwill allocated to that reporting unit. Our adoption of this standard had no impact on our consolidated financial statements and related disclosures.
