Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies Basis of Presentation. The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with GAAP have been condensed or omitted. In our opinion, the accompanying unaudited consolidated financial statements contain all adjustments (consisting only of normal recurring accruals) necessary to present fairly our consolidated financial position as of May 31, 2016, the results of our consolidated operations for the three months and six months ended May 31, 2016 and 2015, and our consolidated cash flows for the six months ended May 31, 2016 and 2015. The results of our consolidated operations for the three months and six months ended May 31, 2016 are not necessarily indicative of the results to be expected for the full year due to seasonal variations in operating results and other factors. The consolidated balance sheet at November 30, 2015 has been taken from the audited consolidated financial statements as of that date. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended November 30, 2015, which are contained in our Annual Report on Form 10-K for that period. Unless the context indicates otherwise, the terms “we,” “our,” and “us” used in this report refer to KB Home, a Delaware corporation, and its subsidiaries. Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Cash and Cash Equivalents. We consider all highly liquid short-term investments purchased with an original maturity of three months or less to be cash equivalents. Our cash equivalents totaled $109.5 million at May 31, 2016 and $342.3 million at November 30, 2015. The majority of our cash and cash equivalents were invested in money market funds and interest-bearing bank deposit accounts. Restricted Cash. Restricted cash at May 31, 2016 and November 30, 2015 consisted of cash deposited with various financial institutions that was required as collateral for our cash-collateralized letter of credit facilities (“LOC Facilities”). Comprehensive Income. Our comprehensive income was $15.6 million for the three months ended May 31, 2016 and $9.6 million for the three months ended May 31, 2015. For the six months ended May 31, 2016 and 2015, our comprehensive income was $28.7 million and $17.4 million, respectively. Our comprehensive income for each of the three-month and six-month periods ended May 31, 2016 and 2015 was equal to our net income for the respective periods. Recent Accounting Pronouncements. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”). The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Companies may use either a full retrospective or a modified retrospective approach to adopt ASU 2014-09. In August 2015, the FASB issued Accounting Standards Update No. 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date,” which delayed the effective date of ASU 2014-09 by one year. In 2016, the FASB issued accounting standards updates that amended several aspects of ASU 2014-09. For public entities, ASU 2014-09, as amended, is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. We are currently evaluating the potential impact of adopting this guidance on our consolidated financial statements. In April 2015, the FASB issued Accounting Standards Update No. 2015-03, “Interest — Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs” (“ASU 2015-03”). ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. ASU 2015-03 is to be applied on a retrospective basis and represents a change in accounting principle. In August 2015, the FASB issued Accounting Standards Update No. 2015-15, “Interest — Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements — Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting” (“ASU 2015-15”), which clarifies the treatment of debt issuance costs from line-of-credit arrangements after the adoption of ASU 2015-03. In particular, ASU 2015-15 clarifies that the SEC staff would not object to an entity deferring and presenting debt issuance costs related to a line-of-credit arrangement as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of such arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. For public entities, ASU 2015-03 and ASU 2015-15 are effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted for financial statements that have not been previously issued. We believe adopting ASU 2015-03 and ASU 2015-15 will not have a material effect on our consolidated financial statements. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). ASU 2016-02 will require organizations that lease assets — referred to as “lessees” — to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. Under ASU 2016-02, a lessee will be required to recognize assets and liabilities for leases with lease terms of more than 12 months. Lessor accounting remains substantially similar to current GAAP. In addition, disclosures of leasing activities are to be expanded to include qualitative along with specific quantitative information. For public entities, ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. ASU 2016-02 mandates a modified retrospective transition method. We are currently evaluating the potential impact of adopting this guidance on our consolidated financial statements. In March 2016, the FASB issued Accounting Standards Update No. 2016-09, “Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”). ASU 2016-09 simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. For public entities, ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the potential impact of adopting this guidance on our consolidated financial statements. Reclassifications. Certain amounts in our consolidated financial statements for prior years have been reclassified to conform to the current period presentation.
