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, 2014, the results of our consolidated operations for the three months and six months ended May 31, 2014 and 2013, and our consolidated cash flows for the six months ended May 31, 2014 and 2013. The results of our consolidated operations for the three months and six months ended May 31, 2014 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, 2013 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, 2013, 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 these estimates. Cash and Cash Equivalents and Restricted Cash. 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 $357.2 million at May 31, 2014 and $436.2 million at November 30, 2013. The majority of our cash and cash equivalents were invested in money market funds and interest-bearing bank deposit accounts. Restricted cash of $44.2 million at May 31, 2014 and $41.9 million at November 30, 2013 consisted of cash deposited with various financial institutions that was required as collateral for our cash-collateralized letter of credit facilities (the “LOC Facilities”). Comprehensive Income (Loss). Our comprehensive income was $26.6 million for the three months ended May 31, 2014 and $37.2 million for the six months ended May 31, 2014. Our comprehensive loss was $3.0 million for the three months ended May 31, 2013 and $15.4 million for the six months ended May 31, 2013. Our comprehensive income (loss) for each of the three-month and six-month periods ended May 31, 2014 and 2013 was equal to our net income (loss) for the same periods. The accumulated other comprehensive loss in our consolidated balance sheets as of May 31, 2014 and November 30, 2013 was comprised solely of adjustments recorded directly to accumulated other comprehensive loss in accordance with Accounting Standards Codification Topic No. 715, “Compensation – Retirement Benefits” (“ASC 715”). Such adjustments are made annually as of November 30, when our benefit plan obligations are remeasured. ASC 715 requires an employer to recognize the funded status of defined postretirement benefit plans as an asset or liability on the balance sheet and requires any unrecognized prior service costs and actuarial gains/losses to be recognized in accumulated other comprehensive income (loss). Recent Accounting Pronouncements. In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2013-11, “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (a consensus of the FASB Emerging Issues Task Force)” (“ASU 2013-11”), which states that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. ASU 2013-11 applies to all entities that have unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. The amendments in ASU 2013-11 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date. Retrospective application is permitted. We believe the adoption of this guidance will not have a material impact on our consolidated financial statements. In April 2014, the FASB issued Accounting Standards Update No. 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity” (“ASU 2014-08”), which raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the new definition of a discontinued operation. It also allows an entity to present a discontinued operation even when it has continuing cash flows and significant continuing involvement with the disposed component. The amendments in ASU 2014-08 are effective prospectively for disposals (or classifications as held for sale) of components of an entity that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years. Early adoption is permitted but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. We believe the adoption of this guidance will not have a material effect on our consolidated financial statements. In May 2014, the 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. To achieve that core principle, an entity should apply the following steps: identify the contract(s) with a customer; identify the performance obligations in the contract; determine the transaction price; allocate the transaction price to the performance obligations in the contract; and recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 supersedes the revenue recognition requirements in Accounting Standards Codification Topic No. 605, “Revenue Recognition,” most industry-specific guidance throughout the industry topics of the accounting standards codification, and some cost guidance related to construction-type and production-type contracts. 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 June 2014, the FASB issued Accounting Standards Update No. 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period” (“ASU 2014-12”). The amendments in ASU 2014-12 require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Accounting Standards Codification Topic No. 718, “Compensation — Stock Compensation” (“ASC 718”), as it relates to awards with performance conditions that affect vesting to account for such awards. The amendments in ASU 2014-12 are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted. Entities may apply the amendments in ASU 2014-12 either: (a) prospectively to all awards granted or modified after the effective date; or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. We believe the adoption of this guidance will not have a material effect on our consolidated financial statements. Reclassifications. Certain amounts in the consolidated financial statements of prior years have been reclassified to conform to the 2014 presentation.

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, 2014, the results of our consolidated operations for the three months and six months ended May 31, 2014 and 2013, and our consolidated cash flows for the six months ended May 31, 2014 and 2013. The results of our consolidated operations for the three months and six months ended May 31, 2014 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, 2013 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, 2013, 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.
