(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, 2010. The Company has made no significant changes to these policies during the nine months ended September 30, 2011.

In accordance with normal practice in the construction industry, the Company includes in current assets and current liabilities amounts related to construction contracts realizable and payable over a period in excess of one year. Costs and estimated earnings in excess of billings related to the Company's contracts and joint venture contracts at September 30, 2011 and December 31, 2010, consisted of the following (in thousands):

	September 30,		December 31,
	2011		2010
Unbilled costs and profits incurred to date*	$	131,038	$	14,285
Unapproved change orders		139,298		49,949
Claims		103,989		75,215
	$	374,325	$	139,449

*	Represents the excess of contract costs and profits recognized to date on the percentage of completion accounting method over the amount of contract billings to date on certain contracts.

Of the balance of “Unapproved change orders” and “Claims” included above in costs and estimated earnings in excess of billings at September 30, 2011 and December 31, 2010, approximately $87.2 million and $74.1 million, respectively, are amounts subject to pending litigation or dispute resolution proceedings as described in Note 7. These amounts are management's estimate of the probable cost recovery from the disputed claims considering such factors as evaluation of entitlement, settlements reached to date and experience with the customer. In the event that future facts and circumstances, including the resolution of disputed claims, cause a reduction in the aggregate amount of the estimated probable cost recovery from the disputed claims, the amount of such reduction will be recorded against earnings in the relevant future period.

In May 2011, the Financial Accounting Standard Board (“FASB”) issued a staff position amending existing guidance for fair value measurements and disclosures in both interim and annual financial statements. This update expands the disclosures for fair value measurements that are estimated using significant unobservable (Level 3) inputs. This update will be effective for the Company with the interim and annual reporting periods for fiscal years beginning after December 15, 2011. Other than requiring additional disclosures, adoption of this update will not have a material effect on the Company's consolidated financial statements.

In June 2011, the FASB issued a staff position which requires an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income, or in two separate but consecutive statements. This update eliminates the option to present components of other comprehensive income as part of the statement of equity. This update will be effective for the Company with the interim and annual reporting periods for fiscal years beginning after December 15, 2011. The adoption of this update will not have a material effect on the Company's consolidated financial statements.

In September 2011, the FASB issued a staff position that gives an entity the option to make a qualitative evaluation about the likelihood of Goodwill impairment. An entity will be required to perform the two-step impairment test only if it concludes that the fair value of a reporting unit is more likely than not less than its carrying value. This update is effective for annual and interim Goodwill impairment tests performed for fiscal years beginning after December 15, 2011, with early adoption permitted. This update will be effective for the Company with the interim and annual reporting periods for fiscal years beginning after December 15, 2011. The adoption of this update will not have a material effect on the Company's consolidated financial statements.

In September 2011, the FASB issued a staff position that revises the way in which entities disclose participation in a multiemployer plan. This update will be effective for the Company with the annual reporting period for the fiscal year ending after December 15, 2011. Other than requiring additional disclosures, adoption of this update will not have a material effect on the Company's consolidated financial statements.
