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, 2015, the results of our consolidated operations for the three months and six months ended May 31, 2015 and 2014, and our consolidated cash flows for the six months ended May 31, 2015 and 2014. The results of our consolidated operations for the three months and six months ended May 31, 2015 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, 2014 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, 2014, 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 informed 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 $285.3 million at May 31, 2015 and $197.7 million at November 30, 2014. 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, 2015 and November 30, 2014 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 $9.6 million for the three months ended May 31, 2015 and $26.6 million for the three months ended May 31, 2014. For the six months ended May 31, 2015 and 2014, our comprehensive income was $17.4 million and $37.2 million, respectively. Our comprehensive income for each of the three-month and six-month periods ended May 31, 2015 and 2014 was equal to our net income for the same 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. ASU 2014-09 is effective for public entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2016. Early adoption is not permitted. Companies may use either a full retrospective or a modified retrospective approach to adopt ASU 2014-09. We are currently evaluating the potential impact of adopting this guidance on our consolidated financial statements. In January 2015, the FASB issued Accounting Standards Update No. 2015-01, “Income Statement — Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items” (“ASU 2015-01”). ASU 2015-01 eliminates the concept of extraordinary items from GAAP but retains the presentation and disclosure guidance for items that are unusual in nature or occur infrequently and expands the guidance to include items that are both unusual in nature and infrequently occurring. ASU 2015-01 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015. A reporting entity may apply ASU 2015-01 prospectively. A reporting entity may also apply ASU 2015-01 retrospectively to all periods presented in the financial statements. We believe the adoption of ASU 2015-01 will not have a material effect on our consolidated financial statements. In February 2015, the FASB issued Accounting Standards Update No. 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis” (“ASU 2015-02”). ASU 2015-02 changes the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. ASU 2015-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. We believe the adoption of ASU 2015-02 will not have a material effect 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. For public entities, ASU 2015-03 is 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. ASU 2015-03 is to be applied on a retrospective basis and represents a change in accounting principle. We believe the adoption of ASU 2015-03 will not have a material effect 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.

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, 2015, the results of our consolidated operations for the three months and six months ended May 31, 2015 and 2014, and our consolidated cash flows for the six months ended May 31, 2015 and 2014. The results of our consolidated operations for the three months and six months ended May 31, 2015 are not necessarily indicative of the results to be expected for the full year due to seasonal variations in operating results and other factors.
