Accounting Policies [Abstract]
New and Pending Accounting Pronouncements	Adoption of New Accounting Standards In March 2016, the FASB issued ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, as part of its simplification initiative. The areas for simplification in this update involve several aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, and the classification on the statement of cash flows. The updated standard is effective for annual and interim periods beginning after December 31, 2016. Effective first quarter 2017, stock-based compensation (SBC) excess tax benefits or deficiencies are reflected in the consolidated statements of income (loss) and comprehensive income (loss) as a component of the provision for income taxes, whereas they previously were recognized in equity to the extent additional paid-in capital pool was available. Additionally, our consolidated statements of cash flows now presents excess tax benefits as an operating activity, with the prior periods adjusted accordingly. Finally, we have elected to account for forfeitures as they occur, rather than estimate expected forfeitures. As a result of the adoption of ASU 2016-09 in first quarter 2017, there were no material impacts to our consolidated financial statements. Pending Accounting Standards In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), requiring an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The updated standard will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method. Early adoption is not permitted. The updated standard becomes effective for annual and interim periods beginning after December 15, 2017. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect initially applying the guidance recognized at the date of initial application (the cumulative catch-up transition method). We currently anticipate adopting the standard using the cumulative catch-up transition method. We anticipate this standard will not have a material impact on our consolidated financial statements. While we are continuing to assess all potential impacts of the standard, we expect revenue related to lot and tract sales to remain substantially unchanged. Due to the complexity of certain of our real estate sale transactions, the revenue recognition treatment required under the standard will be dependent on contract-specific terms, and may vary in some instances from recognition at the time of the sale closing. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), in order to provide increased transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The updated standard is effective for financial statements issued for annual periods beginning after December 15, 2019 and interim periods within fiscal years beginning after December 31, 2020 with early adoption permitted. We are currently evaluating the effect that the updated standard will have on our earnings, financial position and disclosures. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), in order to address eight specific cash flow issues with the objective of reducing the existing diversity in practice. The updated standard is effective for financial statements issued for annual periods beginning after December 15, 2017 and interim periods within those fiscal years with early adoption permitted. We are currently evaluating the effect that the updated standard will have on our earnings, financial position and disclosures. In November, 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230). This ASU requires that a statement of cash flow explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash investments. This standard is effective for fiscal years beginning after December 15, 2017. The adoption of ASU 2016-18 will modify our current disclosures and reclassifications relating to the consolidated statements of cash flows, but we do not expect it to have a material effect on our consolidated financial statements.
