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 accounting principles generally accepted in the U.S. 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 U.S. generally accepted accounting principles (“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 February 28, 2014, the results of our consolidated operations for the three months ended February 28, 2014 and 2013, and our consolidated cash flows for the three months ended February 28, 2014 and 2013. The results of our consolidated operations for the three months ended February 28, 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 $124.2 million at February 28, 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 $42.1 million at February 28, 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 (“LOC Facilities”). Comprehensive Income (Loss). Our comprehensive income for the three months ended February 28, 2014 was $10.6 million. For the three months ended February 28, 2013, our comprehensive loss was $12.5 million. Our comprehensive income (loss) for each of the three-month periods ended February 28, 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 February 28, 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. Reclassifications. Certain amounts in the consolidated financial statements of prior years have been reclassified to conform to the 2014 presentation.
