Significant Accounting Policies	(2) Significant Accounting Policies The significant accounting policies followed by the Company and its subsidiaries in preparing its consolidated financial statements are set forth in Note 1 to such financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. *Recently Issued Accounting Pronouncements* In January 2013, the FASB issued ASU 2013-01, which clarifies which instruments and transactions are subject to the offsetting disclosure requirements established by ASU 2011-11, “Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities.” ASU 2013-01 is effective for the fiscal years beginning on or after January 1, 2013, and interim periods within. Retrospective application is required for any period presented that begins before the entity’s initial application of the new requirements. The adoption of this guidance did not have a material impact on the Company’s financial statements. In February 2013, the FASB issued ASU 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income,” an amendment to FASB ASC Topic 220, “Comprehensive Income”. The update requires disclosure of amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement of operations or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. For amounts not reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. This ASU is effective prospectively for the Company fiscal years, and interim periods within those years beginning after December 15, 2012. The adoption of this guidance did not have a material impact on the Company’s financial statements. In February 2013, the FASB issued ASU 2013-04, which provides guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date. This ASU is an update to FASB ASC Topic 405, “Liabilities”. The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The Company is currently evaluating the impact of this guidance on its financial statements. In July 2013, the FASB issued ASU 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 Emerging Issues Task Force). This ASU addresses when unrecognized tax benefits should be presented as reductions to deferred tax assets for net operating loss carryforwards in the financial statements. This ASU is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption and retrospective application is permitted. The Company is evaluating the potential impact of this adoption on its consolidated financial statements. *Use of and Changes in Estimates* The Company’s construction business involves making significant estimates and assumptions in the normal course of business relating to its contracts and its joint venture contracts. Management focuses on evaluating the performance of contracts individually. These estimates and assumptions can vary in the normal course of business as projects progress, when estimated productivity assumptions change based on experience to date and uncertainties are resolved. Change orders and claims, as well as changes in related estimates of costs to complete, are considered revisions in estimates. The Company uses the cumulative catch-up method applicable to construction contract accounting to account for revisions in estimates. The impact on operating margin in a reporting period and future periods from a change in estimate will depend on the stage of contract completion. During the three and nine months ended September 30, 2013, the Company’s results of operations were impacted by $9.7 million and $11.5 million, respectively, of increases in the estimated recovery projected for a Building segment project due to changes in facts and circumstances that occurred during those periods. These changes in estimates resulted in increases of $9.7 million and $11.5 million in income from construction operations, $6.2 million and $7.2 million in net income and $0.13 and $0.15 in diluted earnings per common share during the three and nine months ended September 30, 2013, respectively. During both the three and nine months ended September 30, 2012, the Company’s results of operations were impacted by a $12.4 million increase in the estimated recovery projected for a large hospitality and gaming project which was primarily driven by changes in cost recovery assumptions based on evidence presented during the period. Excluding the discrete items that impacted the Company’s estimated tax rate during 2012, this change in estimate resulted in increases of $12.4 million in income from construction operations, $7.2 million in net income, and $0.15 in diluted earnings per common share during both the three and nine months ended September 30, 2012. These changes were the only changes in estimates considered material to the Company’s results of operations during the periods presented herein.
