Organization and Basis of Presentation Disclosures	ORGANIZATION AND BASIS OF PRESENTATION Organization and Description of the Business LGI Homes, Inc., a Delaware corporation (the “Company”, “we,” “us,” or “our”), is engaged in the development of communities and the design, construction and sale of new homes in Texas, Arizona, Florida, Georgia, New Mexico, Colorado, North Carolina, South Carolina, Washington, Tennessee, Minnesota, Oklahoma, Alabama, California, Oregon, Nevada, West Virginia, Virginia, Pennsylvania and Maryland. Basis of Presentation The unaudited consolidated 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. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. These financial statements should be read in conjunction with the consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021. The accompanying unaudited consolidated financial statements include all adjustments that are of a normal recurring nature and necessary for the fair presentation of our results for the interim periods presented. Results for interim periods are not necessarily indicative of results to be expected for the full year. The accompanying unaudited financial statements as of September 30, 2022, and for the three and nine months ended September 30, 2022 and 2021, include the accounts of the Company and its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that 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 periods. Actual results could differ from those estimates, and these differences could have a significant impact on the financial statements. Recent Accounting Pronouncements Effective April 28, 2022, we adopted the Financial Accounting Standards Board (the “FASB”) Accounting Standards Update (“ASU”) No. 2020-04, “Reference Rate Reform (“Topic 848”): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU 2020-04”), which provides optional expedients and exceptions for applying 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 because of reference rate reform. Effective April 28, 2022, we adopted FASB ASU No. 2021-01, “Reference Rate Reform (Topic 848): Scope” (“ASU 2021-01”), which clarified the scope and application of the original guidance. The adoption of both ASU 2020-04 and ASU 2021-01 replaced LIBOR as the benchmark interest rate with the Secured Overnight Financing Rate (“SOFR”) and did not have a material effect on our consolidated financial statements or related disclosures.
