TUTOR PERINI CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

(1) Basis of Presentation

The unaudited consolidated condensed financial statements presented herein include the accounts of Tutor Perini Corporation and its wholly owned subsidiaries (“Tutor Perini” or the “Company”).  The Company’s interests in construction joint ventures are accounted for using the proportionate consolidation method.  These unaudited consolidated condensed financial statements have been prepared in accordance with the instructions to Form 10-Q and do not include all of the information and note disclosures required by accounting principles generally accepted in the United States of America.  These statements should be read in conjunction with the financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2011.  In the opinion of management, the accompanying unaudited consolidated condensed financial statements include all adjustments, consisting only of normal recurring adjustments, necessary to present fairly the Company's financial position as of September 30, 2012 and December 31, 2011, results of operations and comprehensive income for the three and nine months ended September 30, 2012 and 2011, and cash flows for the nine months ended September 30, 2012 and 2011. The results of operations for the three and nine months ended September 30, 2012 are not indicative of the results that may be expected for the year ending December 31, 2012 because, among other reasons, such results can vary depending on the timing of progress achieved and changes in estimated profitability of projects being reported.

Prior to the quarterly reporting period ended June 30, 2012, the Company had presented payments related to the deferred purchase price obligation of previous acquisitions within cash flows used by investing activities in the Consolidated Condensed Statement of Cash Flows.  The Company corrected this presentation to appropriately reflect the cash paid to settle the liability recognized at fair value at the conclusion of the measurement period within cash flows used by financing activities, and the remaining cash paid (e.g., changes in fair value of the liability after the conclusion of the measurement period), was reclassified within cash flows used by operating activities.  For the nine months ended September 30, 2012 and 2011 this correction resulted in a decrease in cash flows provided by operating activities of $0 and $1.1 million, an increase in cash flows provided by investing activities of $1.2 million and $3.0 million, and a decrease in cash flows provided by financing activities of $1.2 million and $1.9 million, respectively, in the Consolidated Condensed Statement of Cash Flows. There was no impact on the Company’s Consolidated Condensed Statements of Operations or Balance Sheets previously reported.

The Company considers events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosures.

(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, 2011.  During the nine months ended September 30, 2012, the Company adopted the following accounting pronouncements that were issued in 2011:

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. Other than requiring additional disclosures, adoption of this update has not had 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. The adoption of this update has not had a material effect on the Company's consolidated financial statements.

TUTOR PERINI CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED CONDENSED 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 that adopts this option 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. On January 1, 2012, the Company adopted this option.  The adoption of this option has not had a material effect on the Company’s consolidated financial statements, but it may impact the manner in which the Company performs testing for goodwill impairment.

In July 2012, the FASB issued a staff position that gives an entity the option to make a qualitative evaluation about the likelihood of indefinite-lived intangible asset impairment. An entity that adopts this option will be required to perform the quantitative test only if it concludes that the fair value of the indefinite-lived intangible asset is more likely than not less than its carrying value. The effective date is for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012.  The Company does not expect the adoption of this option to have a material effect on the Company’s consolidated financial statements, but it may impact the manner in which the Company performs testing for indefinite-lived intangible asset impairment.

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, 2012 and December 31, 2011, consisted of the following (in thousands):

	September 30, 2012		December 31, 2011
Unbilled costs and profits incurred to date*	$	141,980	$	107,645
Unapproved change orders		107,786		136,704
Claims		161,896		114,049
	$	411,662	$	358,398

* 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, 2012 and December 31, 2011, approximately $72.2 million and $85.2 million, respectively, are amounts subject to pending litigation or dispute resolution proceedings as described in Note 7 – Contingencies and Commitments.  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.

The Company recognizes revenues from its contracts under the percentage of completion method. In the ordinary course of business, and at a minimum on a quarterly basis, the Company updates projected total contract revenue, cost and profit or loss for each of our contracts based on changes in facts, such as an approved scope change, and changes in estimates. During the three 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 as discussed in Note 8 – Income Taxes, this change in estimate resulted in a $12.4 million increase in income from construction operations, a $7.2 million increase in net income and a $0.15 increase in diluted earnings per common share during the three and nine months ended September 30, 2012. This change was the only change in estimate considered material to the Company's results of operations during the periods presented herein.

(3) Mergers and Acquisitions

(a) Information regarding acquisitions that are material in the aggregate

On January 3, 2011, the Company completed the acquisition of Fisk Electric Company (“Fisk”), a privately held electrical construction company based in Houston, Texas.  Fisk was acquired because the Company believes that it is a strong strategic fit enabling the Company to expand its nationwide electrical construction capabilities and to realize significant synergies and opportunities in support of the Company’s non-residential building and civil operations.  On April 1, 2011, the Company completed the acquisition of Anderson Companies (“Anderson”), the privately held parent company of Roy Anderson Corporation, Harrell Contracting Group, LLC and Brice Building Company, LLC. Anderson was acquired because the Company believes that it is a strong strategic fit for the Company’s building business and strengthens the Company’s position in the southeastern United States.  On June 1, 2011, the Company completed the acquisition of Frontier-Kemper Constructors, Inc. (“Frontier-Kemper”), a privately held Indiana-based corporation. Frontier-Kemper was acquired because the Company believes that it is a strong strategic fit for the Company’s civil business, bolstering the Company’s tunneling business in the United States and expanding the Company’s geographic reach into Canada.  On August 18, 2011, the Company completed the acquisition of Becho, Inc. (“Becho”), a privately held Utah-based corporation. Becho was acquired because the Company believes that it is a strong strategic fit for the Company’s civil business, bolstering the Company’s drilling capabilities in the southwestern United States.

(b)  Merger with GreenStar Services Corporation

On July 1, 2011, the Company acquired GreenStar Services Corporation (“GreenStar”) via a merger of GreenStar into a wholly-owned subsidiary of the Company.  GreenStar is primarily comprised of the following operating entities: Five Star Electric Corporation and WDF, Inc., which are located in New York, and Nagelbush Mechanical, Inc., which is located in Florida. GreenStar was acquired because it is one of the largest specialty contractors in the United States and it will provide an opportunity to expand the Company’s presence in the northeastern markets.

The transaction was accounted for using the acquisition method of accounting.  During the nine months ended September 30, 2012, the Company did not materially revise any of the assumptions, estimates or amounts used to complete its purchase price accounting as of December 31, 2011.

(c) Acquisition of Lunda Construction Company

On July 1, 2011, the Company completed the acquisition of Lunda Construction Company (“Lunda”).  Headquartered in Black River Falls, Wisconsin, and with offices in Wisconsin and Minnesota, Lunda is a heavy civil contractor engaged in the construction, rehabilitation and maintenance of bridges, railroads, and other civil structures in the Midwest and throughout the United States.  Lunda was acquired because the Company believes it is a strong strategic fit for its civil business and will provide the Company with the opportunity to expand its civil business into the Midwestern United States.

The transaction was accounted for using the acquisition method of accounting.  During the nine months ended September 30, 2012, the Company did not materially revise any of the assumptions, estimates or amounts used to complete its purchase price accounting as of December 31, 2011.

(5) Fair Value Measurements

The Company measures certain financial instruments, including cash and cash equivalents, such as money market funds, at their fair values.  The fair values were determined based on a three-tier valuation hierarchy for disclosure of significant inputs.  These hierarchical tiers are defined as follows:

Level 1 –  inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 – inputs are other than quoted prices in active markets that are either directly or indirectly observable through market corroboration.

Level 3 – inputs are unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions based on the best information available in the circumstances.

The following tables provide the assets and liabilities carried at fair value measured on a recurring basis as of September 30, 2012 and December 31, 2011 (in thousands):

(1) Cash, cash equivalents and restricted cash consist primarily of money market funds with original maturity dates of three months or less, for which fair value is determined through quoted market prices.

(2) Short-term investments are classified as other current assets and are comprised of municipal bonds, the majority of which are rated Aa2 or better.  The fair values of the municipal bonds are obtained from readily-available pricing sources for comparable instruments, and as such, the Company has classified these assets as Level 2.

(3) Bonds substituted for retainage are classified as accounts receivable, including retainage and are comprised of U.S. Treasury Notes and other municipal bonds, the majority of which are rated Aa3 or better.  The fair values of these assets are obtained from readily-available pricing sources for comparable instruments, and as such, the Company has classified these assets as Level 2.

(4) At September 30, 2012 the Company had $46.3 million invested in auction rate securities (“ARS”) which the Company considers as available-for-sale long-term investments.  The long-term investments ARS held by the Company at September 30, 2012 are in securities collateralized by student loan portfolios.  At September 30, 2012 most of the Company’s ARS were rated AAA and AA+.  The Company estimated the fair value of its ARS utilizing an income approach valuation model which considered, among other items, the following inputs: (i) the underlying structure of each security; (ii) the present value of future principal and interest payments discounted at rates considered to reflect current market conditions (discount rates range from 3% to 7%); (iii) consideration of the probabilities of default or repurchase at par for each period (term periods range from 6 to 8 years); (iv) prices from recent comparable transactions; and (v) other third party pricing information without adjustment. See the Level 3 ARS rollforward below for disclosure of the Company’s valuation approach.

(5) As discussed in Note 10 – Financial Commitments, the Company entered into a swap agreement with Bank of America, N.A. to establish a long-term interest rate for its $200 million five-year term loan.  The swap agreement became effective for the term loan principal balance outstanding at January 31, 2012 and will remain effective through the maturity date of the term loan.  The Company values the interest rate swap liability utilizing a discounted cash flow model that takes into consideration forward interest rates observable in the market and the counterparty’s credit risk.  This liability is classified as a component of other long-term liabilities.

(6) The liabilities listed as of September 30, 2012 above represent the contingent consideration for the Company’s recent acquisitions for which the measurement period for purchase price analysis has concluded.  See the Level 3 contingent consideration rollforward below for disclosure of the Company’s valuation approach.

The Company has classified its ARS investment as long-term investments in the Consolidated Condensed Balance Sheets as the Company believes the market for government-backed student loans may take in excess of twelve months to fully recover.

The Company performs a fair market value assessment of its auction rate securities (ARS) on a quarterly basis.  To estimate fair value, the Company utilizes an income approach valuation model, with consideration given to market-based valuation inputs.  The model considers, among other items, the following inputs: (i) the underlying structure of each security; (ii) the present value of future principal and interest payments discounted at rates considered to reflect current market conditions (discount rates range from 3% to 7% for investment grade securities); (iii) consideration of the probabilities of default or repurchase at par for each period (term periods range from 6 to 8 years); (iv) prices from recent comparable transactions; and (v) other third party pricing information.

NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

The inputs and the Company’s analysis consider: (i) contractual terms of the ARS instruments; (ii) government-backed guarantees, if any; (iii) credit ratings on the ARS; (iv) current interest rates on the ARS and other market interest rate data; (v) trade data available, including trade data from secondary markets, for the Company’s ARS or similar ARS; (vi) recovery rates for any non-government guaranteed assets; (vii) historical transactions of the Company’s ARS being called at par; (viii) refunding initiatives of ARS; and (ix) risk of downgrade and default.   Current market conditions, including repayment status of student loans, credit market risk, market liquidity and macro-economic influences are reflected in these inputs.

On a quarterly basis, the Company also assesses the recoverability of the ARS balance by reviewing: (i) the regularity and timely payment of interest on the securities; (ii) the probabilities of default or repurchase at par; (iii) the risk of loss of principal from government-backed versus non-government-backed securities; and (iv) the prioritization of the Company’s tranche of securities within the investment in case of default.  The potential impact of any principal loss is included in the valuation model.

When the Company’s analysis indicates an impairment of a security, several factors are considered to determine the proper classification of the charge including: (i) any requirement or intent to sell the security; (ii) failure of the issuer to pay interest or principal; (iii) volatility of fair value; (iv) changes to the ratings of the security; (v) adverse conditions specific to the security or market; (vi) expected defaults; and (vii) length of time and extent that fair value has been less than the cost basis.  The accumulation of this data is used to conclude if a credit loss exists for the specific security, and then to determine the classification of the impairment charge as temporary or other-than-temporary.

In the first quarter of 2012, the Company sold one ARS at auction for its full par value and two ARS in a secondary market. The settlement of the three securities resulted in a pre-tax impairment charge of $2.7 million.

The fair values of the contingent consideration were estimated utilizing an income approach which is based on the cash flows that the acquired entity is expected to generate in the future. This approach requires management to project revenues, operating expenses, working capital investment, capital spending and cash flows for the reporting unit over a multi-year period, as well as determine the weighted average cost of capital to be used as a discount rate (weighted average cost of capital inputs have ranged from 14%-18%).

The carrying amount of cash and cash equivalents approximates fair value due to the short-term nature of these items. The carrying values of receivables, payables, other amounts arising out of normal contract activities, including retainage, which may be settled beyond one year, are estimated to approximate fair value.  Of the Company’s long-term debt, the fair value of the fixed rate senior unsecured notes as of September 30, 2012 was $303.8 million, compared to its carrying value of $298.2 million.  The fair value of the senior unsecured notes was estimated based on market quotations at September 30, 2012.  The carrying value of the remaining balance of the Company’s long-term debt of $402.6 million at September 30, 2012 is estimated to approximate fair value.

There were no significant transfers between Level 1 and Level 2 financial assets and liabilities that are fair valued on a recurring basis during the nine months ended September 30, 2012 and 2011.

(6) Goodwill and Intangible Assets

The Company tests goodwill and intangible assets with indefinite lives for impairment by applying a fair value test in the fourth quarter of each year and between annual tests if events occur or circumstances change which suggest that the goodwill or intangible assets should be evaluated.  Intangible assets with finite lives are also tested for impairment whenever events or circumstances indicate that the carrying value may not be recoverable.  During the second quarter of 2012, the Company experienced a sustained decrease in its stock price, causing its market capitalization to be substantially less than its carrying value and its implied control premium to increase beyond the implied control premium that was reconciled in its 2011 annual impairment analysis, and beyond the observable market comparable level.  Additionally, deterioration in broader market conditions including stock market volatility, particularly in the construction industry, impacted the weighted average cost of capital rate assumptions used in deriving the fair values of the Company’s reporting units, which are based primarily on market inputs.  Finally, several of the Company’s reporting units experienced degradation in the timing of projected cash flows used in deriving the fair values of those reporting units in its 2011 annual impairment analysis caused by delays in the timing of awards and start of new work that the Company anticipated would enter into backlog in the first half of 2012, and a general decrease in profit margins on new work awards that were factored into the Company’s forecast assumptions.

In the Building reporting unit, the most significant decrease in estimated new work cash flow was the result of political decisions that negatively impacted the advance of a large project for an existing customer.  In addition, the Company observed an unfavorable change in the margin mix of new work obtained in the first half of 2012 compared with prior years.  The majority of the new work awards in the first half of 2012 as well as the near term new work prospects were comprised of lower margin private client work and not the higher margin public works the Building reporting unit completed in the past. The projected cash flows for the Building reporting unit as of June 30, 2012 took into consideration the changes in assumptions on new work awards and unfavorable change in margin mix, consistent with its actual results in the first half of 2012.

In the Civil reporting unit, the fourth quarter of 2011 valuation anticipated the award and start and/or ramp-up of a number of projects during 2012.  Many of these projects were delayed for several reasons including political pressures, timing of funding, and general economic concerns.  The change in the estimated timing of recent awards and resulting ramp-up of production resulted in deterioration in anticipated future cash flows from fourth quarter of 2011 expectations. The projected cash flows for the Civil reporting unit as of June 30, 2012 took into consideration the change in estimated timing of award and ramp-up of new work.

Within the Management Services reporting unit valuation for the fourth quarter of 2011, cash flow projections included the anticipated ramp-up of work associated with the movement of Pacific Marine Corps operations from the island of Okinawa to the island of Guam. During April 2012, United States bipartisan legislators were unable to come to agreement on government spending cuts and certain government projects were suspended.  This left doubt around the timing and magnitude of the proposed move. The projected cash flows for the Management Services reporting unit as of June 30, 2012 took into consideration the uncertainty of timing surrounding significant projects with the Pacific Marine Corps on the island of Guam.

Based on these circumstances and events, the Company performed an interim goodwill and indefinite lived intangible asset impairment test as of June 30, 2012 and, as a result, the Company recorded a goodwill impairment charge of $321.1 million and an indefinite lived intangible assets impairment charge of $16.4 million in the second quarter of 2012.  The Company also evaluated its finite lived tangible and intangible assets due to the degradation in the timing of projected cash flows since the Company’s 2011 impairment analysis and changes in the planned use of certain intangible assets, and this analysis resulted in a $39.1 million impairment charge on the Company’s finite lived intangible assets in the second quarter of 2012. These non-cash charges did not impact the Company’s overall business operations.

The first step in the two-step process of the impairment analysis was to determine the fair value of the Company and each of its reporting units and compare the fair value of each reporting unit to its carrying value. If the carrying value of the reporting unit exceeded its fair value, a second step was followed to calculate the goodwill impairment. The second step involved determining the fair value of the individual assets and liabilities of the reporting unit that failed the first step and calculating the implied fair value of goodwill. To determine the fair value of the Company and each of its reporting units, the Company utilized both an income-based valuation approach as well as a market-based valuation approach.  The income-based valuation approach was based on the cash flows that the reporting unit expected to generate in the future and required the Company to project revenues, operating expenses, working capital investment, capital spending and cash flows for the reporting unit in a discrete period, as well as to determine the weighted average cost of capital to be used as a discount rate and a terminal value growth rate for the non-discrete period.  The market-based valuation approach to estimate the fair value of the Company’s reporting units utilized industry multiples of revenues and operating earnings.  The Company equally weighted the fair values calculated under the income-based and market-based valuation approaches in arriving at the concluded fair values of its reporting units.

As part of the valuation process, the aggregate fair value of the Company was compared to its market capitalization at the valuation date in order to determine the implied control premium.  The implied control premium was then compared to the control premiums paid in recent transactions within the industry.  The Company’s implied market control premium of 78.1% and 42.5%, as of the fourth quarter of 2011 and the second quarter of 2012 valuation, respectively, were determined to be in an acceptable range of market transactions observed in the construction and engineering industry in the past seven years.

As part of the review process for the reporting unit valuations, the Company created multiple income-based and market-based valuation models to understand the sensitivity of the variables used in determining the fair value. These models were reviewed with the Company’s external fair value specialists who assisted in the process by providing insight into acceptable ranges on various valuation assumptions as well as preferred valuation techniques.

Impairment assessment inherently involves management judgments as to the assumptions used to project these amounts and the impact of market conditions on those assumptions. The key assumptions that the Company used to estimate the fair value of its reporting units under the income-based approach were as follows:

· Weighted average cost of capital used to discount the projected cash flows;

· Cash flows generated from existing and new work awards; and

· Projected operating margins.

Weighted average cost of capital rates used to discount the projected cash flows were developed via the capital asset pricing model which is primarily based upon market inputs.  The Company used discount rates that management felt were an accurate reflection of the risks associated with the forecasted cash flows of its respective reporting units.  Weighted average cost of capital inputs ranged from 15% - 16.5% for the Company’s reporting units.  As discussed above, since the Company’s 2011 annual impairment analysis, the weighted average cost of capital rates were impacted by broader market conditions including the recent stock market volatility, particularly in the construction industry.

To develop the cash flows generated from new work awards and future operating margins, the Company tracked prospective work for each of its reporting units primarily on a project-by-project basis as well as the estimated timing of when the work would be bid or prequalified, started and completed.  The Company also gave consideration to its relationships with the prospective owners, the pool of competitors that were capable of performing large, complex work, changes in business strategy, and the Company’s history of success in winning new work in each reporting unit.  With regard to operating margins, the Company gave consideration to its historical reporting unit operating margins in the end markets that the prospective work opportunities were most significant, current market trends in recent new work procurement, and changes in business strategy.

NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

Similar to previous valuations, the Company noted that small changes to valuation assumptions could have a significant impact on the concluded value; however, the Company gained comfort over the assumptions selected for valuation through comparison to historical transaction benchmarks, third party industry expectations, and the Company’s previous models.

The Company also estimated the fair value of its reporting units under a market-based approach by applying industry-comparable multiples of revenues and operating earnings to its reporting units’ projected performance.  The conditions and prospects of companies in the construction industry depend on common factors such as overall demand for services.

Changes in the Company’s assumptions or estimates could materially affect the determination of the fair value of a reporting unit.  Such changes in assumptions could be caused by:

· Terminations, suspensions, reductions in scope or delays in the start up of the revenues and cash flows from backlog as well as the prospective work tracked;

· Reductions in available government, state and local agencies and non-residential private industry funding and spending;

· The Company’s ability to effectively compete for new work and maintain and grow market penetration in the regions that the Company operates in;

· The Company’s ability to successfully control costs, work schedule, and project delivery; or

· Broader market conditions, including stock market volatility in the construction industry and its impact on the weighted average cost of capital assumption.

With regard to the Company’s reporting units, the carrying values of the Company’s Building, Civil and Management Services reporting units were greater than their fair values, and as such, the Company performed the second step of the goodwill impairment test for these reporting units which resulted in goodwill impairments as discussed above. In this second step, the Company determined the fair value of the individual assets and liabilities of the reporting units that failed Step 1 and calculated the implied fair value of goodwill for those reporting units.  The Company included in this calculation the valuation of assets and liabilities that would occur in a theoretical purchase price allocation of the reporting unit in accordance with the Financial Accounting Standards Board’s (the “FASB”) Accounting Standards Codification (“ASC”) 805 – Business Combinations, as well as the value of backlog, trade name, and customer relationships and the impact of deferred tax liabilities and assets arising from the fair valuation of these assets and liabilities.

The fair value of the Specialty Contractors reporting unit substantially exceeded its carrying value, and as such, it was not necessary to perform the second step of the goodwill impairment test for this reporting unit.

In conducting the initial step of its goodwill evaluation, the Company also evaluated its finite lived tangible and intangible assets due to the degradation in the timing of projected cash flows since the Company’s 2011 impairment analysis and changes in the planned use of certain intangible assets.  The Company compared the fair value of the finite lived tangible and intangible assets to their carrying value and determined that the carrying value of a portion of these assets exceeded their fair value as determined by the income-based valuation approach and by benchmarking against observable market prices.  This income-based valuation approach involved key assumptions similar to those used in the goodwill impairment analysis for the Company’s reporting units as discussed above, (e.g. projections of future cash flows associated with the Company’s trade name, contractor license, customer relationship and contract backlog intangible assets that were recorded in previous acquisitions).  This analysis resulted in an impairment charge of $39.1 million associated with its finite lived intangible assets.

(7) Contingencies and Commitments

The Company and certain of its subsidiaries are involved in litigation and are contingently liable for commitments and performance guarantees arising in the ordinary course of business. The Company and certain of its clients have made claims arising from the performance under their contracts. The Company recognizes certain significant claims for recovery of incurred cost when it is probable that the claim will result in additional contract revenue and when the amount of the claim can be reliably estimated. These assessments require judgments concerning matters such as litigation developments and outcomes, the anticipated outcome of negotiations, the number of future claims and the cost of both pending and future claims.  In addition, because most contingencies are resolved over long periods of time, liabilities may change in the future due to various factors.

Several matters are in the litigation and dispute resolution process.  The following discussion provides a background and current status of these matters.

Tutor-Saliba-Perini Joint Venture vs. Los Angeles MTA Matter

During 1995 Tutor-Saliba-Perini (“Joint Venture”) filed a complaint in the Superior Court of the State of California for the County of Los Angeles against the Los Angeles County Metropolitan Transportation Authority (“LAMTA”), seeking to recover costs for extra work required by LAMTA in connection with the construction of certain tunnel and station projects. In 1999, LAMTA countered with civil claims under the California False Claims Act against the Joint Venture, Tutor-Saliba and the Company jointly and severally (together, “TSP”).

Between 2005 and 2010, the court granted certain Joint Venture motions and LAMTA capitulated on others which reduced the number of false claims LAMTA may seek and limited LAMTA’s claims for damages and penalties.  In September 2010, LAMTA dismissed its remaining claims and agreed to pay the entire amount of the Joint Venture’s remaining claims plus interest.   The Court subsequently entered judgment in favor of TSP and against LAMTA in the amount of $3 million.  This amount is after deducting the amount of $0.5 million, representing the tunnel handrail verdict plus accrued interest against TSP.  The parties filed post-trial motions for costs and fees.  The Court ruled TSP’s sureties could recover costs, LAMTA could recover costs for the tunnel handrail trial, and no party could recover attorneys’ fees.  TSP is appealing the false claims jury verdict on the tunnel handrail claim and other issues, including the denial of TSP’s and its Sureties’ request for attorneys’ fees.  LAMTA subsequently filed its notice of cross-appeal.  In March 2012, the Court finalized the preparation of the record for the Court of Appeal; opening briefs were filed in August 2012.  The appeal of this case is expected to take at least a year.

The Company does not expect this matter to have any material effect on its consolidated financial statements.

Perini/Kiewit/Cashman Joint Venture-Central Artery/Tunnel Project Matter

Perini/Kiewit/Cashman Joint Venture (“PKC”), a joint venture in which the Company holds a 56% interest and is the managing partner, is currently pursuing a series of claims, instituted at different times over the course of the past ten years, for additional contract time and/or compensation against the Massachusetts Highway Department (“MHD”) for work performed by PKC on a portion of the Central Artery/Tunnel (“CA/T”) project in Boston, Massachusetts.  During construction, MHD ordered PKC to perform changes to the work and issued related direct cost changes with an estimated value, excluding time delay and inefficiency costs, in excess of $100 million. In addition, PKC encountered a number of unforeseen conditions during construction that greatly increased PKC’s cost of performance. MHD has asserted counterclaims for liquidated damages and backcharges.

Certain of PKC’s claims have been presented to a Disputes Review Board (“DRB”) which consists of three construction experts chosen by the parties. To date, five DRB panels have issued several awards and interim decisions in favor of PKC’s claims, amounting to total awards to PKC in excess of $128 million plus interest, of which $110 million were binding awards.

In December 2010, the Suffolk County Superior Court granted MHD’s motion for summary judgment to vacate the Third DRB Panel’s awards to PKC for approximately $56.5 million.  The Court granted the motion on the grounds that the arbitrators do not have authority to decide whether particular claims are subject to the arbitration provision of the contract.  MHD subsequently moved to vacate approximately $13.7 million of the Fourth DRB Panel’s total awards to PKC on the same arbitrability basis that the Third DRB’s awards were vacated.  In October 2011, the Suffolk County Superior Court followed its earlier arbitrability rulings holding that the Fourth DRB exceeded its authority in deciding arbitrability with respect to certain of the Fourth DRB Panel’s awards (approximately $8 million of the $13.7 million discussed above).  PKC is pursuing an appeal of the Superior Court decisions.

In February 2012, PKC received a $22 million payment for an interest award associated with the Second DRB panel’s awards to PKC.  No trial date has been set in any of the cases as the parties are currently awaiting a decision on the appeal of the Superior Court arbitrability rulings.

Long Island Expressway/Cross Island Parkway Matter

The Company reconstructed the Long Island Expressway/Cross Island Parkway Interchange (the “Project”) for the New York State Department of Transportation (the “NYSDOT”). The $130 million Project was substantially completed in January 2004 and was accepted by the NYSDOT as finally complete in February 2006. The Company incurred significant added costs in completing its work and suffered extended schedule costs due to numerous design errors, undisclosed utility conflicts, lack of coordination with local agencies and other interferences for which the Company believes that the NYSDOT is responsible.

In March 2011, the Company filed its claim and complaint with the New York State Court of Claims and served to the New York State Attorney General’s Office, in the amount of $53.8 million.  In May 2011, the NYSDOT filed a motion to dismiss the Company’s claim on the grounds that the Company had not provided required documentation for project closeout and filing of a claim.  In September 2011, the Company reached agreement on final payment with the Comptroller’s Office on behalf of the NYSDOT which resulted in an amount of $0.5 million payable to the Company and formally closed out the project, which allowed the Company’s claim to be re-filed.  The Company re-filed its claim in the amount of $53.8 million with the NYSDOT in February 2012 and with the Court of Claims in March 2012.  In May 2012, the NYSDOT served its answer and counterclaims in the amount of $151 million alleging fraud in the inducement and punitive damages related to disadvantaged business enterprise (“DBE”) requirements for the Project.  The Company does not expect the counterclaim to have any material effect on its consolidated financial statements.

Management has made an estimate of the total anticipated recovery on this project and it is included in revenue recorded to date.  To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the financial statements at that time.

Queensridge Matter

Tutor Perini Building Corp. (“TPBC”) (formerly Perini Building Company, Inc.), a wholly owned subsidiary of the Company, was the general contractor for the construction of One Queensridge Place, a condominium project in Las Vegas, Nevada.  The developer of the project, Queensridge Towers, LLC / Executive Home Builders, Inc. (“Queensridge”), has failed to pay TPBC for work which PBC and its subcontractors performed on the project.

In October 2012, TPBC and Queensridge reached an agreement to settle their respective claims.  The settlement did not have a material effect on the Company’s consolidated financial statements.

Gaylord Hotel and Convention Center Matter

In 2005, Gaylord National, LLC (“Gaylord”), as Owner, and Perini Building Company, Inc. / Tompkins Builders, Joint Venture (“PTJV”), as Construction Manager, entered into a contract to construct the Gaylord National Resort and Convention Center (the “Project”) in Maryland. The Project is complete and as part of its settlement with Gaylord reached in November 2008, PTJV agreed to pay all subcontractors and defend all claims and lien actions by them relating to the Project.  PTJV has closed out most subcontracts.  Resolution of the issues with the remaining subcontractors may require mediation, arbitration and/or trial.

PTJV is pursuing an insurance claim for approximately $40 million related to work performed by Banker Steel Company, Inc. (“Banker Steel”), a subcontractor, including $11 million for business interruption costs incurred by Gaylord which have effectively been assigned to PTJV. In November 2009, PTJV filed suit against Factory Mutual Insurance Co. (“FM”) in the Maryland federal district court alleging FM breached the insurance contracts and for declaratory judgment with respect to the insurance coverage.  In December 2010, PTJV filed suit against ACE American Insurance Company (“ACE”) in Maryland federal district court alleging ACE breached the general liability insurance contract, requesting a declaratory judgment with respect to the insurance coverage and for bad faith.  FM and ACE each brought separate motions for summary judgment.  In October, 2012, FM’s motion was denied; ACE’s motion was granted.

Fontainebleau Matter

Desert Mechanical Inc. (“DMI”) and Fisk, wholly owned subsidiaries of the Company, were subcontractors on the Fontainebleau Project in Las Vegas (“Fontainebleau”), a hotel/casino complex with approximately 3,800 rooms.  In June 2009, Fontainebleau filed for bankruptcy protection, under Chapter 11 of the U.S. Bankruptcy Code, in the Southern District of Florida.  Fontainebleau is headquartered in Miami, Florida.

DMI and Fisk filed liens in Nevada for approximately $44 million, representing unreimbursed costs to date and lost profits, including anticipated profits.  Other unaffiliated subcontractors have also filed liens. In June 2009, DMI filed suit against Turnberry West Construction, Inc. (“Turnberry”), the general contractor, in the 8th Judicial District Court, Clark County, Nevada, and in May 2010, the court entered an order in favor of DMI for approximately $45 million.  DMI is uncertain as to Turnberry’s present financial condition.

In January 2010, the Bankruptcy Court approved the sale of the property to Icahn Nevada Gaming Acquisition, LLC and this transaction closed in February 2010.  As a result of a July 2010 ruling relating to certain priming liens, there is now approximately $125 million set aside from this sale, which is available for distribution to satisfy the creditor claims based on seniority.  The total estimated sustainable lien amount is approximately $350 million.  The project lender filed suit against the mechanic’s lien claimants, including DMI and Fisk, alleging that certain mechanic’s liens are invalid and that all mechanic’s liens are subordinate to the lender's claims against the property.  The Nevada Supreme Court ruled in October in an advisory opinion at the request of the Bankruptcy Court that lien priorities would be determined in favor of the mechanic lien holders under Nevada law.

Management has made an estimate of the total anticipated recovery on this project and it is included in revenue recorded to date.  To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the financial statements at that time.

MGM CityCenter Matter

Tutor Perini Building Corp. (“TPBC”) (formerly Perini Building Company, Inc.), a wholly owned subsidiary of the Company, contracted with MGM MIRAGE Design Group (“MGM”) in March 2005 to construct the CityCenter project in Las Vegas, Nevada (the “Project”).  The Project, which encompasses nineteen separate contracts, is a 66-acre urban mixed use development consisting of hotels, condominiums, retail space and a casino.

The Company achieved substantial completion of the Project in December 2009, and MGM opened the Project to the public on the same date.  In March 2010, the Company filed suit against MGM and certain other property owners in the Clark County District Court alleging several claims including breach of contract, among other items.

In a Current Report on Form 8-K filed by MGM in March 2010, and in subsequent communications issued, MGM has asserted that it believes it owes substantially less than the claimed amount and that it has claims for losses in connection with the construction of the Harmon Hotel and is entitled to unspecified offsets for other work on the Project. According to MGM, the total of the offsets and the Harmon Hotel claims exceed the amount claimed by the Company.

In May 2010, MGM filed a counterclaim and third party complaint against the Company and its subsidiary TPBC. The court granted the Company and MGM’s joint motion to consolidate all subcontractor initiated actions into the main CityCenter lawsuit.  MGM filed a motion to demolish the Harmon Tower, one of the CityCenter buildings.  In July 2012, the Court determined that MGM can demolish the Harmon Tower as a “business decision” but that doing so would not be the result of any actions by TPBC during the construction of the project and that the Court’s decision is not “a determination as to whether any design defects exist, any noncompliance with code exists, any nonconformance with plans exists or any construction defects exist.”

Evidence had been presented at the hearing that the Harmon Tower could be repaired for approximately $21 million, more than $15 million of which is due to design defects that are MGM’s responsibility.  In August 2012, as part of MGM’s motion to demolish the Harmon Tower, the Court found that MGM's testing methodology of extrapolation cannot be presented to a jury.  In mid-September MGM filed a request for additional destructive testing.  In October 2012, the Court ruled it would allow additional testing but with certain conditions including but not limited to the Court’s withdrawing MGM’s right to demolish the Harmon and severing the Harmon defects issue from the rest of the case.  There will be two cases and two separate juries.

With respect to alleged losses at the Harmon Hotel, the Company has contractual indemnities from the responsible subcontractor, as well as existing insurance coverage that it expects will be available and sufficient to cover any liability that may be associated with this matter.  The Company’s insurance carrier initiated legal proceedings seeking declaratory relief that their insurance policies do not provide for defense or coverage for matters pertaining to the Harmon Towers.  Those proceedings are stayed pending the outcome of the underlying dispute in Nevada District Court.  The Company is not aware of a basis for other claims that would amount to material offsets against what MGM owes to the Company.  The Company does not expect this matter to have any material effect on its consolidated financial statements.

As of September 2012, MGM has reached agreements with subcontractors to settle at a discount $301 million of amounts previously billed to MGM.  The Company has reduced and will continue to reduce amounts included in revenues, cost of construction operations, accounts receivable and accounts payable for the reduction in subcontractor pass-through billings, which the Company would not expect to have an impact on recorded profit.  At September 30, 2012, the Company had approximately $192 million recorded as contract receivables for amounts due and owed to the Company and its subcontractors.  In December 2011, a portion of the amounts owed to one of the Company’s subsidiaries, Fisk, was paid for approximately $15 million.  Included in the Company’s receivables are pass-through subcontractor billings for contract work and retention, and other requests for equitable adjustment for additional work in the amount of $48 million.  As pass-through subcontractor billings are settled, the Company will reduce its mechanic’s lien as appropriate. As of September 30, 2012, the Company’s mechanic’s lien against the project was $191.3 million.

Management has made an estimate of the total anticipated recovery on this project and it is included in revenue recorded to date.  To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the financial statements at that time.

Honeywell Street/Queens Boulevard Bridges Matter

In 1999, the Company was awarded a contract for reconstruction of the Honeywell Street/Queens Boulevard Bridges (the “Project”) for the City of New York (the “City”).  In June 2003, after substantial completion of the Project, the Company initiated an action to recover $8.75 million in claims against the City on behalf of itself and its subcontractors. In March 2010, the City filed counterclaims for $74.6 million and other relief, alleging fraud in connection with the DBE requirements for the Project. In May 2010, the Company served the City with its response to the City’s counterclaims and affirmative defenses.   No trial date has been set.

The Company does not expect this matter to have any material effect on its consolidated financial statements.

Westgate Planet Hollywood Matter

Tutor-Saliba Corporation (“TSC”), a wholly owned subsidiary of the Company, contracted to construct a time share development in Las Vegas (the “Project”) which was substantially completed in December 2009.  The Company’s claims against the owner, Westgate Planet Hollywood Las Vegas, LLC (“WPH”), relate to unresolved owner change orders and other claims.  The Company filed a lien on the project in the amount of $23.2 million, and filed its complaint with the District Court, Clark County, Nevada.  Included in the Company’s receivables are pass-throughsubcontractor billings for contract work and retention of approximately $12 million. Several subcontractors have also recorded liens, some of which have been released by bonds and some of which have been released as a result of subsequent payment.  Westgate has posted a mechanic’s lien release bond for $22.3 million.

WPH filed a cross-complaint alleging non-conforming and defective work for approximately $51 million, primarily related to alleged defects, misallocated costs, and liquidated damages.  Some or all of the allegations will be defended by counsel appointed by TSC’s insurance carrier.  WPH has since revised the amount of their counterclaims to approximately $45 million.

Two subcontractor claims have settled before trial.  Trial on the remaining issues began in October 2012, and is currently ongoing.

The Company does not expect this matter to have any material effect on its consolidated financial statements.  Management has made an estimate of the total anticipated recovery on this project and it is included in revenue recorded to date.  To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the financial statements at that time.

100th Street Bus Depot Matter

The Company constructed the 100th Street Bus Depot for the New York City Transit Authority (“NYCTA”) in New York.  Prior to receiving notice of final acceptance from the NYCTA, this project experienced a failure of the brick façade on the building due to faulty subcontractor work.  The Company has not yet received notice of final acceptance of this project from the NYCTA.  The Company contends defective structural installation by the Company’s steel subcontractor caused or was a causal factor of the brick façade failure.

The Company has tendered its claim to the NYCTA Owner Controlled Insurance Program (“OCIP”) and to Chartis Claims, Inc., its insurance carrier.  Coverage was denied in January 2011.  The OCIP and general liability carriers have filed a declaratory relief action in the United States District Court, Southern District of New York against the Company seeking court determination that no coverage is afforded under their policies.  The Company believes it has legal entitlement to recover costs under the policies and pursuing its claim against the carriers for breach of contract and appropriate associated causes of action.  The Company has filed its amended answer and counterclaims in response to the declaratory relief action.  The Court had scheduled a bench trial for the declaratory relief causes of action for September 2012.  Chartis and Lloyd's filed motions for summary judgment on declaratory relief issues in mid-September.  The Court adjourned the September trial date and set motions for summary judgment for late November 2012.

Management has made an estimate of the total anticipated recovery on this project and it is included in revenue recorded to date.  To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the financial statements at that time.

Brightwater Matter

In 2006, the Department of Natural Resources and Parks Wastewater Treatment Division of King County (“King County”), as Owner, and Vinci Construction Grands Projects/Parsons RCI/Frontier-Kemper, Joint Venture (“VPFK”), as Contractor, entered into a contract to construct the Brightwater Conveyance System and tunnel sections (the “Project”) in Washington State. Frontier-Kemper, a wholly owned subsidiary of the Company, is a 20% minority partner in the joint venture.

In April 2010, King County filed a lawsuit alleging damages in the amount of $74 million, plus costs, for VPFK’s failure to complete specified components of the project in the King County Superior Court, State of Washington. Shortly thereafter, VPFK filed a counterclaim in the amount of approximately $75 million, seeking reimbursement for additional costs incurred as a result of differing site conditions, King County’s defective specifications, for damages sustained on VPFK’s tunnel boring machines (“TBM”), and increased costs as a result of hyperbaric interventions. VPFK’s claims related to differing site conditions, defective design specifications, and damages to the TBM were presented to a Dispute Resolution Board (“DRB”).  King County amended the amount sought in its lawsuit to approximately $132 million.  In August 2011, the DRB generally found that King County was liable to VPFK for VPFK’s claims for encountering differing site conditions, including damages to the TBM, but not on VPFK’s alternative theory of defective specifications.  From June through August 2012, each party filed several motions for summary judgment on certain claims and requests in preparation for trial, which were heard and ruled upon by the Court. The Court granted and denied various requests of each party related to evidence and damages.

Trial started in early September and is currently ongoing.

The ultimate financial impact of King County’s lawsuit is not yet determinable.  Management has made an estimate of the total anticipated recovery on the submitted claims and it is included in revenue recorded to date.  To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the financial statements at that time.

156 Stations Matter

In December 2003, Five Star Electric Corporation (“FSE”), a wholly owned subsidiary of the Company, entered into an agreement with the Prime Contractor Transit Technologies, L.L.C (“Transit”), a Consortium member of Siemens Transportation Transit Technologies, L.L.C (“Siemens”), to assist in the installation of new public address and customer information screens system for each of the 156 stations for the New York City Transit Authority (“NYCTA”) as the owner. Work on the project commenced in early 2004 and is substantially complete.

In June 2007, FSE submitted a Demand for Arbitration against Transit to terminate FSE’s subcontract due to: the execution of a Cure Agreement between the NYCTA, Siemens and Transit, which amended FSE’s rights under the Prime Contract; Transit’s failure to provide information and equipment to allow work to progress according to the approved schedule, and for failure to tender payment in excess of a year. In June 2012, the arbitration panel awarded FSE a total of approximately $11.9 million to be paid within 45 days, and Transit’s claims were denied.  FSE filed a motion to confirm arbitration award in District Court in July 2012.  In late August 2012, Transit Technologies filed a cross petition to vacate the award.  A decision from the Court is expected by the end of 2012.  The eventual resolution of this matter is not expected to have a material effect on the Company’s consolidated financial statements.

(8) Income Taxes

The Company’s effective tax rate for the nine months ended September 30, 2012 and 2011 was 3.9% and 36.8%, respectively.  The effective tax rate for the nine months ended September 30, 2012 excludes $3.6 million of certain discrete expense items related to an increase in unrecognized tax benefits of $1.1 million and an adjustment of $2.5 million, both associated with certain stock-based compensation items identified in March 2012.  Other discrete items include $4.9 million related to the change in the Company’s forward looking state rate and $0.9 million of benefits claimed on the tax return in excess of the prior year’s income tax provision, offset by $5.0 million of additional tax benefits derived from purchased entities and a $1.0 million reversal of tax reserves.  The Company’s provision for income taxes and effective tax rate for the nine months ended September 30, 2012 were significantly impacted by the goodwill and intangible asset impairment charge discussed in Note 6 – Goodwill and Intangible Assets above.  Of the total goodwill and intangible asset impairment charge of $376.6 million, approximately $255.0 million pertained to goodwill or intangible assets that yielded permanent differences between book income and taxable income. The Company has tax effected the impairment charge for the current year-to-date period based on its estimated annual effective tax rate of 3.9%, which resulted in a reduction in its provision for income taxes of approximately $37.4 million during the period.  Additionally, approximately $47.7 million was recorded as a reduction in previously recorded deferred tax liabilities due to the impairment charge.

For financial statement purposes the Company uses the more-likely-than-not recognition threshold and a tax benefit measurement process for recording changes to unrecognized tax benefits. The Company recognizes interest and penalties on any income tax liabilities as a component of its income tax provision. The total amount of gross unrecognized tax benefits recorded was approximately $2.0 million and $1.7 million as of September 30, 2012 and December 31, 2011, respectively.

The Company’s 2010 U.S. Federal tax return is currently being audited by the Internal Revenue Service.

(9) Stock-Based Compensation

The Tutor Perini Long-Term Incentive Plan (the “Plan”) allows the Company to grant stock-based compensation awards in a variety of forms including restricted stock and stock options.  The terms and conditions of the awards granted are established by the Compensation Committee of the Company’s Board of Directors, who administers the Plan.

For the three and nine month periods ended September 30, 2012, the Company recognized total stock-based compensation expense of $2.3 million and $7.4 million, respectively, in general and administrative expenses For the three and nine month periods ended September 30, 2011, the Company recognized a credit of $0.3 million and total stock-based compensation expense of $6.8 million, respectively, in general and administrative expenses.

Restricted Stock Awards

Restricted stock awards vest subject to the satisfaction of service requirements or the satisfaction of both service requirements and achievement of certain performance targets.  Upon vesting, each award is exchanged for one share of the Company’s common stock.  The grant date fair values of these awards are determined based on the closing price of the Company’s common stock on either the award date (if subject only to service conditions), or the date that the Compensation Committee establishes the applicable performance target (if subject to performance conditions).   As of September 30, 2012, the Compensation Committee has approved the grant of an aggregate of 4,875,833 restricted stock awards to eligible participants.

In March 2012, the Compensation Committee established the 2012 pre-tax income performance targets for 220,000 restricted stock units awarded in 2009 and 2010.  In May and June 2012, the Compensation Committee approved the award of 783,333 new restricted stock units.  Additionally, 120,833 restricted stock units were forfeited during the nine months ended September 30, 2012.

Stock Options

Stock option awards generally vest subject to the satisfaction of service requirements or the satisfaction of both service requirements and achievement of certain performance targets. The grant date fair values of these awards are determined based on the Black-Scholes option price model on either the award date (if subject only to service conditions), or, the date that the Compensation Committee establishes the applicable performance target (if subject to performance conditions).  The related compensation expense is amortized over the applicable requisite service period.  The exercise price of the options is equal to the closing price of the Company’s common stock on the date the awards were approved by the Compensation Committee, and the awards expire ten years from the award date. As of September 30, 2012, the Compensation Committee has approved an aggregate of 2,380,465 stock option awards to eligible participants.

In March 2012 the Compensation Committee established the 2012 pre-tax income performance target for 150,000 stock options awarded in 2009. In May and June 2012 the Compensation Committee approved the award of 695,000 new stock options.  Additionally, 75,000 stock options were forfeited during the nine months ended September 30, 2012.

For the three and nine months ended September 30, 2012, the Company recognized compensation expense of $0.5 million and $1.9 million, respectively, related to stock option awards.  As of September 30, 2012, there was $2.4 million of unrecognized compensation expense related to the outstanding options which, absent significant forfeitures in the future, is expected to be recognized over a weighted average period of approximately 2.7 years.

A summary of stock option activity under the Plan for the nine months ended September 30, 2012 is as follows:

				Weighted Average
	Number of Shares			Grant Date Fair Value		Exercise Price
Total Granted and Outstanding - January 1, 2012		1,225,465		$	10.11	$	18.45
Granted		165,000		$	5.65	$	19.51
Forfeited		(75,000	)	$	7.20	$	-
Total Granted and Outstanding		1,315,465		$	9.72	$	18.91

Total Awarded and Outstanding – September 30, 2012		2,145,465		n.a.		$	16.55

(a) Grant date fair value cannot be determined currently because the related performance targets for future years have not yet been established by the Compensation Committee.

There were 490,465 options that have vested and were exercisable at September 30, 2012 at a weighted average exercise price of $19.79 per share. Of the remaining options outstanding, approximately 592,500 will vest based on the satisfaction of service requirements and 1,062,500 will vest based on the satisfaction of both service requirements and the achievement of certain performance targets.

At September 30, 2012, the outstanding options of 1,315,465 shares had an intrinsic value of $0.1 million and a weighted average remaining contractual life of 6.8 years.

(10) Financial Commitments

Amended Credit Agreement

On August 2, 2012, the Company entered into a First Amendment (the “First Amendment”) to its Fifth Amended and Restated Credit Agreement (the “Credit Agreement”) entered into on August 3, 2011 as Borrower, with Bank of America, N.A., as Administrative Agent, Swing Line Lender and L/C Issuer (the “Lender”).  The First Amendment modifies the financial covenants under the Credit Agreement beginning for the period ended September 30, 2012 to allow for more favorable minimum net worth, minimum fixed charge and maximum leverage ratios for the Company and also to add new financial covenants including minimum liquidity and consolidated senior leverage ratio covenants.  The First Amendment also increases the sublimit for letters of credit from $50 million to $150 million.

Under the First Amendment, the minimum net worth covenant is modified such that the consolidated net worth of the Company cannot be less than the sum of: (i) 85% of the consolidated net worth as of March 31, 2012 less the actual goodwill and intangible assets impairment charge taken on or before September 30, 2012, not to exceed $450.0 million; (ii) an amount equal to 50% of net income for each fiscal quarter ending after June 30, 2012 (with no deduction for net losses); and (iii) an amount equal to 100% of the aggregate amount of all equity issuances after June 30, 2012 that increase stockholder’s equity.  The minimum fixed charge ratio covenant is modified such that the minimum fixed charge ratio shall not be less than 1.00 to 1.00 for the quarterly periods ending September 30, 2012 and December 31, 2012, 1.10 to 1.00 for the quarterly periods ending March 31, 2013 and June 30, 2013, and 1.25 to 1.00 for the quarterly periods ending September 30, 2013 and thereafter.  The consolidated leverage ratio covenant is modified such that the consolidated leverage ratio shall not be greater than 4.25 to 1.00 for the quarterly periods ending September 30, 2012 through March 31, 2013, 3.75 to 1.00 for the quarterly periods ending June 30, 2013 through December 31, 2013, 3.25 to 1.00 for the quarterly periods ending March 31, 2014 through September 30, 2014 and 2.75 to 1.00 for the quarterly periods ending December 31, 2014 and thereafter.  The First Amendment allows for an add-back to EBITDA of up to $450.0 million for any goodwill and intangible asset impairment charges that impact the ratios for all fiscal quarters through March 31, 2013.

The First Amendment also modifies the applicable interest rates for amounts outstanding such that they bear interest at a rate equal to, at the Company's option, (a) the adjusted British Bankers Association LIBOR rate, as defined, plus 200 to 400 basis points (floor of 200 basis points) based on the ratio of consolidated funded indebtedness of the Company and its subsidiaries to consolidated EBITDA or (b) the higher of the Federal Funds Rate plus 50 basis points, or the prime rate announced by Bank of America, N.A., plus up to 300 basis points based on the ratio of consolidated funded indebtedness of the Company and its subsidiaries to consolidated EBITDA.  In addition, the Company has agreed to pay quarterly facility fees ranging from 0.375% to 0.700% per annum of the unused portion of the credit facility.

The Credit Agreement allows the Company to borrow up to $300 million on a revolving credit basis (the “Revolving Facility”), with a $150 million sublimit for letters of credit, and an additional $200 million term loan (the “Term Loan”).  Subject to certain conditions, the Company has the option to increase the base facility by up to an additional $50 million.  Substantially all of the Company’s subsidiaries unconditionally guarantee the obligations of the Company under the Credit Agreement.  The obligations under the Credit Agreement are secured by a lien on all personal property of the Company and its subsidiaries party thereto.  Any outstanding loans under the Revolving Facility mature on August 3, 2016, while the Term Loan includes quarterly installments of principal and interest payable over a five-year period.  The Term Loan balance has been paid down to $161.3 million at September 30, 2012.

The Company was in compliance with the modified financial covenants under the First Amendment for the period ended September 30, 2012.

The Company had $70.0 million of outstanding borrowings under its Revolving Facility as of September 30, 2012 and no outstanding borrowings as of December 31, 2011.  The Company utilized the Revolving Facility for letters of credit in the amount of $0.2 million and $3.0 million as of September 30, 2012 and December 31, 2011, respectively.  Accordingly, at September 30, 2012, the Company had $229.8 million available to borrow under the Credit Agreement.

On August 26, 2011, the Company entered into a swap agreement (“Swap Agreement”) with Bank of America, N.A. to establish a long-term interest rate for the Term Loan discussed above.  The Swap Agreement pertains to the Term Loan principal balance outstanding at January 31, 2012 and will remain effective through the maturity date of the Term Loan.  Amounts outstanding under the Swap Agreement will bear interest at a rate equal to the Applicable Rate, as defined in the Credit Agreement (based upon the Company’s consolidated leverage ratio), plus 97.5 basis points. The Swap Agreement includes quarterly installments of principal and monthly installments of interest payable through the maturity date of the Term Loan.

(11) Earnings (Losses) per Common Share

Basic earnings (losses) per common share were computed by dividing net income by the weighted average number of common shares outstanding.  Diluted earnings (losses) per common share were similarly computed after giving consideration to the dilutive effect of stock options and restricted stock awards outstanding on the weighted average number of common shares outstanding. The computation of diluted earnings (loss) per common share for the three months ended September 30, 2012 excludes 1,315,465 stock option shares, and for the nine months ended September 30, 2012 excludes 1,315,465 stock option shares and 1,358,332 restricted stock units, respectively, because these shares would have an antidilutive effect.  The computation of diluted earnings per common share for the three and nine months ended September 30, 2011 excludes 247,500 restricted stock units and 920,465 stock options.

Item 2.  Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discusses our financial position at September 30, 2012, and the results of our operations for the three and nine months ended September 30, 2012 and should be read in conjunction with: (1) the unaudited consolidated condensed financial statements and notes contained herein, and (2) the consolidated financial statements and accompanying notes to our Annual Report on Form 10-K for the fiscal year ended December 31, 2011.

Overview

We were incorporated in 1918 as a successor to businesses that had been engaged in providing construction services since 1894.  We provide diversified general contracting, construction management and design-build services to private clients and public agencies throughout the world.  Our construction business is conducted through four basic segments or operations:  Civil, Building, Specialty Contractors and Management Services.  Our Civil segment specializes in public works construction and the repair, replacement and reconstruction of infrastructure, including highways, bridges, mass transit systems and water and wastewater treatment facilities, primarily in the western, northeastern and mid-Atlantic United States.  Our Building segment has significant experience providing services to a number of specialized building markets, including the hospitality and gaming, transportation, healthcare, municipal offices, sports and entertainment, educational, correctional facilities, biotech, pharmaceutical and high-tech markets.  Our Specialty Contractors segment specializes in plumbing, HVAC, electrical, mechanical, and pneumatically placed concrete for a full range of civil, building and management services construction projects in the industrial, commercial, hospitality and gaming, and transportation end markets, among others.   Our Management Services segment provides diversified construction and design-build services to the U.S. military and federal government agencies, as well as surety companies and multi-national corporations in the United States and overseas.

The contracting and management services that we provide consist of general contracting, pre-construction planning and comprehensive management services, including planning and scheduling the manpower, equipment, materials and subcontractors required for the timely completion of a project in accordance with the terms and specifications contained in a construction contract.  We also offer self-performed construction services including site work, concrete forming and placement, steel erection, electrical and mechanical, plumbing and HVAC.  We provide these services by using traditional general contracting arrangements, such as fixed price, guaranteed maximum price and cost plus fee contracts and, to a lesser extent, construction management or design-build contracting arrangements.  In the ordinary course of our business, we enter into arrangements with other contractors, referred to as “joint ventures,” for certain construction projects.  Each of the joint venture participants is usually committed to supply a predetermined percentage of capital, as required, and to share in a predetermined percentage of the income or loss of the project.  Generally, each joint venture participant is fully liable for the obligations of the joint venture.

We believe our leadership position as the contractor of choice for large, complex civil and nonresidential building projects will support our long term backlog growth and provide further visibility into the future earnings of our business.  We have capitalized on this leadership position with significant new awards and low bids across each of our segments, including the recently announced award for the Hudson Yards development project, which will be booked into backlog as various phases are released.  We expect to continue to leverage our increased self-performance and schedule control capabilities to obtain additional large scale Civil and Building backlog awards in the near term.

For the three months ended September 30, 2012, we recorded revenues of $1,099.4 million, income from construction operations of $54.7 million and net income of $42.6 million, as compared to revenues of $1,166.4 million, income from construction operations of $62.0 million and net income of $35.5 million for the three months ended September 30, 2011.  For the nine months ended September 30, 2012, we recorded revenues of $2,997.3 million, loss from construction operations of $282.5 million and net loss of $307.0 million, as compared to revenues of $2,601.6 million, income from construction operations of $117.6 million and net income of $62.1 million for the nine months ended September 30, 2011. Our results of operations for the nine months ended September 30, 2012 were materially impacted by a $376.6 million goodwill and intangible asset impairment charge ($339.2 million after-tax), as discussed in further detail under the Critical Accounting Policies below.  We performed an interim impairment test of goodwill and intangible assets during the three months ended June 30, 2012, due to the fact that the Company experienced a sustained decrease in its stock price, causing its market capitalization to be substantially less than its carrying value and its implied control premium to increase beyond the implied control premium that was reconciled in our 2011 annual impairment analysis, and beyond the observable market comparable level.  Additionally, deterioration in broader market conditions including recent stock market volatility, particularly in the construction industry, impacted the weighted average cost of capital rate assumptions used in deriving the fair values of our reporting units, which are based primarily on market inputs.  Finally, several of our reporting units experienced degradation in the timing of projected cash flows used in deriving the fair values of those reporting units in our 2011 annual impairment analysis caused by delays in the timing of the award and start of new work.

Our volume increased during 2012 primarily due to the contributions from our acquisitions, partially offset by the substantial completion of several successful large public works and hospitality and gaming projects in 2011. Our income from operations and operating margins decreased due to several factors including: the substantial completion of several successful large public works projects in early 2011, the current under absorption of our general and administrative expenses, particularly in our Building segment, as we are starting up several high-quality pending award and prospect projects, and an unfavorable change in new work margin mix.  This decrease was partially offset by increases in the estimated recoveries on certain large projects based on changes in facts and circumstances surrounding those projects that occurred during the period and by increased contributions from our 2011 acquisitions.  We continue to experience strong contributions from our Specialty Contractors segment, consistent with our strategy of focusing on the growth of our self-performance capabilities.  Our Management Services segment is focused on obtaining new work with various U.S. government agencies, including the U.S. military, both domestically and abroad as evidenced by its consistent backlog.  Our net income reflects the impacts of a $37.4 million reduction in our provision for income taxes recorded due to the goodwill and intangible asset impairment charges, a $3.6 million increase to our provision for income taxes due to discrete tax adjustments identified in March 2012 as well as a $2.7 million loss on the sale of a portion of our auction rate securities.  We also had increased interest expense with our term loan which was entered into in August 2011, and increased amortization of acquisition-related intangible assets.

At September 30, 2012, we had working capital of $638.7 million, a ratio of current assets to current liabilities of 1.48 to 1.00, and a ratio of long-term debt to equity of 0.58 to 1.00 as compared to working capital of $556.8 million, a ratio of current assets to current liabilities of 1.40 to 1.00 and a ratio of long-term debt to equity of 0.44 to 1.00 at December 31, 2011.  Our stockholders’ equity decreased to $1.1 billion as of September 30, 2012, as compared to $1.4 billion as of December 31, 2011.  The increase in our long-term debt to equity ratio and the decrease in our stockholders’ equity at September 30, 2012 primarily reflect the impact of the $376.6 million goodwill and intangible asset impairment charge ($339.2 million after tax) recorded during the second quarter of 2012.

47

To supplement our unaudited consolidated financial statements presented based on accounting principles generally accepted in the United States of America (“GAAP”), we sometimes use non-GAAP measures of income from operations, net income, earnings per share and other measures that we believe are appropriate to enhance an overall understanding of our historical financial performance and future prospects. We are providing these non-GAAP measures to disclose additional information to facilitate the comparison of past and present operations, and they are among the indicators management uses as a basis for evaluating the Company’s financial performance as well as for forecasting future periods. For these reasons, management believes these non-GAAP measures can be useful operating performance measures to be considered by investors, potential investors and others.  These measures are not intended to replace the presentation of our financial results in accordance with GAAP, and they may not be comparable to other similarly titled measures of other companies.

Recent Developments

Backlog of $5.6 Billion and Recent Pending Awards

Our backlog of uncompleted construction work at September 30, 2012 was approximately $5.6 billion compared to $6.1 billion at December 31, 2011.  During the three months ended September 30, 2012 we converted a number of pending awards into backlog across each of our business segments, and we had adjustments to existing contracts.  Significant awards included a $181 million hospitality and gaming project, a $73 million educational facility, and a $63 million stadium renovation project. In addition, we have significant pending contract awards, including projects such as the Hudson Yards development, low bids on civil mass transit and bridge projects and various specialty contracts that we anticipate will enter into backlog in the near future as the contracts for these projects are executed.  We are continuing to track several large scale civil and building prospects for both public and private sector customers as we continue to leverage our self-performance and schedule control capabilities.

Critical Accounting Policies

Our significant accounting policies are described in Note 1 of Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2011.  Our critical accounting policies are also identified and discussed in Item 7 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2011.  During the nine months ended September 30, 2012, we adopted the following accounting pronouncements that were issued in 2011:

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. Other than requiring additional disclosures, adoption of this update has not had a material effect on our 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. The adoption of this update has not had a material effect on our 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 that adopts this option 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. On January 1, 2012, we adopted this option.  The adoption of this option has not had a material effect on our consolidated financial statements, but it may impact the manner in which we perform testing for goodwill impairment.

In July 2012, the FASB issued a staff position that gives an entity the option to make a qualitative evaluation about the likelihood of indefinite-lived intangible asset impairment. An entity that adopts this option will be required to perform the quantitative test only if it concludes that the fair value of the indefinite-lived intangible asset is more likely than not less than its carrying value. The effective date is for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012.  We do not expect the adoption of this option to have a material effect on our consolidated financial statements, but it may impact the manner in which we perform testing for indefinite-lived intangible asset impairment.

Impairment of goodwill and intangible assets -We test goodwill and intangible assets with indefinite lives for impairment by applying a fair value test in the fourth quarter of each year and between annual tests if events occur or circumstances change which suggest that the goodwill or intangible assets should be evaluated.  Intangible assets with finite lives are also tested for impairment whenever events or circumstances indicate that the carrying value may not be recoverable.  During the second quarter of 2012, the Company experienced a sustained decrease in its stock price, causing its market capitalization to be substantially less than its carrying value and its implied control premium to increase beyond the implied control premium that was reconciled in its 2011 annual impairment analysis, and beyond the observable market comparable level.  Additionally, deterioration in broader market conditions including stock market volatility, particularly in the construction industry, impacted the weighted average cost of capital rate assumptions used in deriving the fair values of our reporting units, which are based primarily on market inputs.  Finally, several of our reporting units experienced degradation in the timing of projected cash flows used in deriving the fair values of those reporting units in our 2011 annual impairment analysis caused by delays in the timing of awards and start of new work that we anticipated would enter into backlog in the first half of 2012, and a general decrease in profit margins on new work awards that were factored into our forecast assumptions.

In the Building reporting unit, the most significant decrease in estimated new work cash flow was the result of political decisions that negatively impacted the advance of a large project for an existing customer.  In addition, we observed an unfavorable change in the margin mix of new work obtained in the first half of 2012 compared with prior years.  The majority of the new work awards in the first half of 2012 as well as the near term new work prospects were comprised of lower margin private client work and not the higher margin public works the Building reporting unit completed in the past.  The projected cash flows for the Building reporting unit as of June 30, 2012 took into consideration the changes in assumptions on new work awards and unfavorable change in margin mix, consistent with its actual results in the first half of 2012.

50

In the Civil reporting unit, the fourth quarter of 2011 valuation anticipated the award and start and/or ramp-up of a number of projects during 2012.  Many of these projects were delayed for several reasons including political pressures, timing of funding, and general economic concerns.  The change in estimated  timing of recent awards and resulting ramp-up of production resulted in deterioration in anticipated future cash flows from fourth quarter of 2011 expectations. The projected cash flows for the Civil reporting unit as of June 30, 2012 took into consideration the change in estimated timing of award and ramp-up of new work.

Within the Management Services reporting unit valuation for the fourth quarter of 2011, cash flow projections included the anticipated ramp-up of work associated with the movement of Pacific Marine Corps operations from the island of Okinawa to the island of Guam. During April 2012, United States bipartisan legislators were unable to come to agreement on government spending cuts and certain government projects were suspended.  This left doubt around the timing and magnitude of the proposed move. The projected cash flows for the Management Services reporting unit as of June 30, 2012 took into consideration the uncertainty of timing surrounding the significant projects with the Pacific Marine Corps on the island of Guam.

Based on these circumstances and events, we performed an interim goodwill and indefinite lived intangible asset impairment test as of June 30, 2012 and, as a result, we recorded a goodwill impairment charge of $321.1 million and an indefinite lived intangible assets impairment charge of $16.4 million in the second quarter of 2012.  We also evaluated our finite lived tangible and intangible assets due to the degradation in the timing of projected cash flows since our 2011 impairment analysis and changes in the planned use of certain intangible assets, and this analysis resulted in a $39.1 million impairment charge on our finite lived intangible assets in the second quarter of 2012. These non-cash charges did not impact our overall business operations.

The first step in the two-step process of the impairment analysis was to determine the fair value of the Company and each of its reporting units and compare the fair value of each reporting unit to its carrying value. If the carrying value of the reporting unit exceeded its fair value, a second step was followed to calculate the goodwill impairment. The second step involved determining the fair value of the individual assets and liabilities of the reporting unit that failed the first step and calculating the implied fair value of goodwill. To determine the fair value of the Company and each of its reporting units, we utilized both an income-based valuation approach as well as a market-based valuation approach.  The income-based valuation approach was based on the cash flows that the reporting unit expected to generate in the future and required us to project revenues, operating expenses, working capital investment, capital spending and cash flows for the reporting unit in a discrete period, as well as to determine the weighted average cost of capital to be used as a discount rate and a terminal value growth rate for the non-discrete period.  The market-based valuation approach to estimate the fair value of our reporting units utilized industry multiples of revenues and operating earnings.  We equally weighted the fair values calculated under the income-based and market-based valuation approaches in arriving at the concluded fair values of our reporting units.

As part of the valuation process, the aggregate fair value of the Company was compared to its market capitalization at the valuation date in order to determine the implied control premium.  The implied control premium was then compared to the control premiums paid in recent transactions within the industry.  The Company’s implied market control premium of 78.1% and 42.5%, as of the fourth quarter of 2011 and the second quarter of 2012 valuation, respectively, were determined to be in an acceptable range of market transactions observed in the construction and engineering industry in the past seven years.

51

As part of the review process for the reporting unit valuations, we created multiple income-based and market-based valuation models to understand the sensitivity of the variables used in determining the fair value. These models were reviewed with our external fair value specialists who assisted in the process by providing insight into acceptable ranges on various valuation assumptions as well as preferred valuation techniques.

Impairment assessment inherently involves management judgments as to the assumptions used to project these amounts and the impact of market conditions on those assumptions. The key assumptions that we used to estimate the fair value of our reporting units under the income-based approach were as follows:

· Weighted average cost of capital used to discount the projected cash flows;

· Cash flows generated from existing and new work awards; and

· Projected operating margins.

Weighted average cost of capital rates used to discount the projected cash flows were developed via the capital asset pricing model which is primarily based upon market inputs.  We used discount rates that management felt were an accurate reflection of the risks associated with the forecasted cash flows of our respective reporting units.  Weighted average cost of capital inputs ranged from 15% -16.5% for our reporting units.  As discussed above, since our 2011 annual impairment analysis, the weighted average cost of capital rates were impacted by broader market conditions including the recent stock market volatility, particularly in the construction industry.

To develop the cash flows generated from new work awards and future operating margins, we tracked prospective work for each of our reporting units primarily on a project-by-project basis as well as the estimated timing of when the work would be bid or prequalified, started and completed.  We also gave consideration to our relationships with the prospective owners, the pool of competitors that were capable of performing large, complex work, changes in business strategy, and our history of success in winning new work in each reporting unit.  With regard to operating margins, we gave consideration to our historical reporting unit operating margins in the end markets that the prospective work opportunities were most significant, current market trends in recent new work procurement, and changes in business strategy.

Similar to previous valuations, we noted that small changes to valuation assumptions could have a significant impact on the concluded value; however, we gained comfort over the assumptions selected for our valuation through comparison to historical transaction benchmarks, third party industry expectations, and our previous models.

We also estimated the fair value of our reporting units under a market-based approach by applying industry-comparable multiples of revenues and operating earnings to our reporting units’ projected performance.  The conditions and prospects of companies in the construction industry depend on common factors such as overall demand for services.

Changes in our assumptions or estimates could materially affect the determination of the fair value of a reporting unit.  Such changes in assumptions could be caused by:

· Terminations, suspensions, reductions in scope or delays in the start up of the revenues and cash flows from backlog as well as the prospective work tracked;

· Reductions in available government, state and local agencies and non-residential private industry funding and spending;

· Our ability to effectively compete for new work and maintain and grow market penetration in the regions that we operate in;

52

· Our ability to successfully control costs, work schedule, and project delivery; or

· Broader market conditions, including stock market volatility in the construction industry and its impact on the weighted average cost of capital assumption.

With regard to our reporting units, the carrying values of our Building, Civil and Management Services reporting units were greater than their fair values, and as such, we performed the second step of the goodwill impairment test for these reporting units which resulted in goodwill impairments as discussed above. In this second step, we determined the fair value of the individual assets and liabilities of the reporting units that failed Step 1 and calculated the implied fair value of goodwill for those reporting units.  We included in this calculation the valuation of assets and liabilities that would occur in a theoretical purchase price allocation of the reporting unit in accordance with the Financial Accounting Standards Board’s (the “FASB”) Accounting Standards Codification (“ASC”) 805 – Business Combinations, as well as the value of backlog, trade name, and customer relationships and the impact of deferred tax liabilities and assets arising from the fair valuation of these assets and liabilities.

The fair value of our Specialty Contractors reporting unit substantially exceeded its carrying value, and as such, it was not necessary to perform the second step of the goodwill impairment test for this reporting unit.

In conducting the initial step of our goodwill evaluation, we also evaluated our finite lived tangible and intangible assets due to the degradation in the timing of projected cash flows since our 2011 impairment analysis and changes in the planned use of certain intangible assets.  We compared the fair value of the finite lived tangible and intangible assets to their carrying value and determined that the carrying value of a portion of these assets exceeded their fair value as determined by the income-based valuation approach and by benchmarking against observable market prices.  This income-based valuation approach involved key assumptions similar to those used in the goodwill impairment analysis for our reporting units as discussed above, (e.g. projections of future cash flows associated with our trade name, contractor license, customer relationship and contract backlog intangible assets that were recorded in previous acquisitions).  This analysis resulted in an impairment charge of $39.1 million associated with our finite lived intangible assets.

During the third quarter of 2012, we completed our evaluation of the key assumptions used in our interim impairment analysis of goodwill and intangible assets with indefinite lives, and concluded that there were no adjustments required to be made to the impairment charges recorded in the second quarter of 2012.

Changes in estimates- We recognize revenues from our contracts under the percentage of completion method.  In the ordinary course of business, and at a minimum on a quarterly basis, we update projected total contract revenue, cost and profit or loss for each of our contracts based on changes in facts, such as an approved scope change, and changes in estimates.  Normal, recurring changes in estimates include, but are not limited to: (i) changes in estimated scope as a result of unapproved or unpriced customer change orders; (ii) changes in estimated productivity assumptions based on experience to date; (iii) changes in estimated materials costs based on experience to date; (iv) changes in estimated subcontractor costs based on subcontractor buyout experience; (v) changes in the timing of scheduled work that may impact future costs; (vi) achievement of incentive income; and (vii) changes in estimated recoveries through the settlement of litigation.  During the three months ended September 30, 2012, our 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 our estimated tax rate, this change in estimate resulted in a $12.4 million increase in our income from construction operations, a $7.2 million increase in our net income and a $0.15 increase in our diluted earnings per common share during the three and nine months ended September 30, 2012.  This change was the only change in estimate considered material to our results of operations during the periods presented herein.

Results of Operations

Comparison of the Third Quarter Ended September 30, 2012 with the Third Quarter Ended September 30, 2011

During the third quarter of 2012, we recorded revenues of $1,099.4 million, income from construction operations of $54.7 million and a net income of $42.6 million as compared to revenues of $1,166.4 million, income from construction operations of $62.0 million and net income of $35.5 million during the third quarter of 2011.  Basic and diluted earnings per common share for the third quarter of 2012 were $0.90 and $0.88, respectively, as compared to basic and diluted earnings per common share of $0.75 and $0.74, respectively, for the same period in 2011.  Excluding the impact of the discrete items discussed above, we would have had net income of $25.8 million and diluted earnings per common share of $0.54 for the third quarter of 2012.

Total	$	1,099.4	$	1,166.4	$	(67.0	)		(5.7	)%

Building segment revenues decreased by $102.8 million (or 20.8%), from $493.8 million during the third quarter of 2011 to $391.0 million during the third quarter of 2012 due primarily to the completion of a large, successful public works project and large hospitality and gaming projects. These decreases were partially offset by increased activity in healthcare and office facility projects and a hospitality and gaming project.

Civil segment revenues increased by $69.5 million (or 25.1%), from $276.8 million during the third quarter of 2011 to $346.3 million during the third quarter of 2012, due primarily to increased activity in certain tunnel projects on the West Coast and several highway and bridge projects on the East Coast and Midwest that were awarded in 2011 and early 2012. These increases were partially offset by the substantial completion of a large transportation project.

Specialty Contractors segment revenues decreased by $20.6 million (or 6.1%), from $335.9 million during the third quarter of 2011 to $315.3 million during the third quarter of 2012 due primarily to the substantial completion of several specialty subcontracts for a large hospitality and gaming project in 2011 partially offset by the start up of new work in 2012.

Management Services segment revenues decreased by $13.1 million (or 21.9%), from $59.9 million during the third quarter of 2011 to $46.8 million during the third quarter of 2012 due primarily to the substantial completion of an overhead coverage project in Iraq in 2011 and reduced activity on a task order contract for containerized housing in southern Iraq.

Building segment income from construction operations increased by $12.0 million (or 134.8%), from $8.9 million during the third quarter of 2011 to $20.9 million during the third quarter of 2012 due primarily to increases in the estimated recoveries on certain large hospitality and gaming, healthcare, and condominium projects based on changes in facts and circumstances surrounding those projects that occurred during the period.  Our Building segment income from construction operations and operating margins were also impacted by efficiencies realized on certain healthcare facility projects.  These increases were offset by declines in income from operations due to the decline in revenues discussed above.

Civil segment income from construction operations increased by $2.5 million (or 10.5%), from $23.8 million during the third quarter of 2011 to $26.3 million during the third quarter of 2012, due primarily to the increased volume discussed above.  This increase was partly offset by a decline in operating margin due primarily to the substantial completion of several successful public works projects on the East Coast in 2011 and legal costs incurred during the period on projects where we are actively pursuing recovery.

Specialty Contractors segment income from construction operations decreased by $18.9  million (or 57.1%), from $33.1 million during the third quarter of 2011 to $14.2 million during the third quarter of 2012 due primarily to the favorable performance and successful close out of several projects in 2011 as well as the decline in revenues discussed above.

Management Services segment income from construction operations decreased by $2.6 million (or 48.2%), from $5.4 million during the third quarter of 2011 to $2.8 million during the third quarter of 2012 due primarily to the favorable close out of certain U.S. military facilities in Iraq in 2011.

Corporate general and administrative expenses were relatively flat at $9.5 million during the third quarter of 2012 compared to $9.2 million during the third quarter of 2011.

Other income (expense), net decreased by $5.4 million from $5.9 million during the third quarter of 2011 to $0.5 million during the third quarter of 2012 due primarily to the bargain purchase gain of approximately $4.0 million recorded on the acquisition of Frontier-Kemper in the third quarter of 2011.  Interest expense remained relatively flat at $11.0 million during the third quarter of 2012 compared to $11.6 million during the third quarter of 2011.  Income tax expense decreased by $19.3 million to $1.6 million during the third quarter of 2012 compared to $20.9 million during the third quarter of 2011 due primarily to the impact of the impairment charge discussed above which resulted in a $16.8 million reduction in our provision for income taxes in 2012.  We anticipate our effective tax rate to approximate 3.9% for the remainder of 2012 primarily due to the impairment charge.

Comparison of the Nine Months Ended September 30, 2012 with the Nine Months Ended September 30, 2011

During the nine months ended September 30, 2012, we recorded revenues of $2,997.3 million, loss from construction operations of $282.5 million and a net loss of $307.0 million as compared to revenues of $2,601.6 million, income from construction operations of $117.6 million and net income of $62.1 million during the nine months ended September 30, 2011.  Basic and diluted loss per common share for the nine months ended September 30, 2012 were $6.47 and $6.47, respectively, as compared to basic and diluted earnings per common share of $1.32 and $1.30, respectively, for the nine months ended September 30, 2011.   Excluding the impact of the discrete items discussed above, we would have had income from construction operations and net income of $94.0 million and $37.4 million, respectively, and diluted earnings per common share of $0.78 for the nine months ended September 30, 2012.

Building segment revenues decreased by $317.5 million (or 23.0%), from $1,379.6 million during the nine months ended September 30, 2011 to $1,062.1 million during the same period in 2012 due primarily to the completion of a large, successful public works project and large hospitality and gaming projects. These decreases were partially offset by the acquisition of Anderson Companies (“Anderson”), which contributed approximately $336.2 million to 2012 revenues, an increase of $117.6 million from its contributions of $218.6 million to 2011 revenues, as well as increased activity in certain healthcare facility, office facility, and courthouse projects.

Civil segment revenues increased by $371.1 million (or 67.7%), from $548.3 million during the nine months ended September 30, 2011 to $919.4 million during the same period in 2012 due primarily to the acquisitions of Frontier-Kemper, Lunda and Becho in mid-2011 which contributed approximately $454.1 million to 2012 revenues in the aggregate, an increase of $300.9 million from their contributions of $153.2 million to 2011 revenues.  Civil segment revenues also increased due to increased activity in certain tunnel projects on the West Coast and several highway and bridge projects on the East Coast and Midwest that were awarded in 2011 and early 2012.

Specialty Contractors segment revenues increased by $343.8 million (or 66.8%), from $514.8 million during the nine months ended September 30, 2011 to $858.6 million during the same period in 2012, due primarily to the acquisition of FSE, WDF and Nagelbush in mid-2011 which contributed approximately $605.6 million to 2012 revenues in the aggregate, an increase of approximately $356.5 million from their contributions of $249.1 million to 2011 revenues.

The following discussion of income from construction operations during the nine months ended September 30, 2012 and 2011 has been prepared on a pre-impairment charge basis in order to enable users of this information to better compare normal operating results of each segment between the two periods. Since the impairment charge impacts 2012 only and does not affect revenues, cost of revenues or general expenses we incur to conduct our day-to-day construction operations, management believes the following discussion, analysis and comparison of year-to-date 2012 and 2011 operating results is more meaningful to users when prepared on a pre-impairment charge basis.

Building segment income from construction operations on a pre-impairment charge basis decreased $46.2 million (or 105.7%), from income of $43.7 million during the nine months ended September 30, 2011 to a loss of $2.5 million during the same period in 2012 due primarily to the decline in volume discussed above, sustained general and administrative expenses as we awaited the start up of several large pending projects, the favorable close out of certain projects in 2011, and certain unrecoverable costs incurred on an educational facility in 2012.  Our Building segment operating margins have also been impacted by an underlying change in mix of work from public to the more competitive private market.  These decreases were offset by efficiencies realized on certain healthcare facility projects and an increase in estimated recoveries on certain large hospitality and gaming, and healthcare projects based on changes in facts and circumstances surrounding those projects that occurred during the period.

Civil segment income from construction operations on a pre-impairment charge basis increased by $17.2 million (or 33.3%), from $51.7 million  during the nine months ended September 30, 2011 to $68.9 million during the same period in 2012 due primarily to the contributions from our acquisitions discussed above of approximately $34.3 million (net of intangible assets amortization), an increase of $22.2 million from their contributions of $12.1 million to 2011 income from construction operations, as well as the increased volume discussed above.  This increase was partly offset by a decline in operating margin due primarily to the substantial completion and favorable close out of certain successful public works projects on the East Coast in 2011.

57

Specialty Contractors segment income from construction operations on a pre-impairment charge basis increased by $18.0 million (or 50.3%), from $35.8 million during the nine months ended September 30, 2011 to $53.8 million during the same period in 2012 due primarily to the acquisitions discussed above which contributed approximately $47.2 million in income from construction operations (net of intangible assets amortization) in the aggregate, an increase of $19.1 million from their contributions of $28.1 million to 2011 income from construction operations.

Management Services segment income from construction operations on a pre-impairment charge basis decreased by $8.0 million (or 54.8%), from $14.6 million during the nine months ended September 30, 2011 to $6.6 million during the same period in 2012, due primarily to the favorable close out of certain projects in Iraq in 2011.

Corporate general and administrative expenses increased by $4.5 million (or 16.0%) from $28.2 million during the nine months ended September 30, 2011 to $32.7 million during the same period in 2012 due primarily to increased expenses associated with integration and system conversion activities and a change in the methodology of allocating corporate expenses to our segments.

Other (expense) income, net decreased from income of $6.6 million during the nine months ended September 30, 2011 to an expense of $0.7 million during the same period in 2012, due primarily to a loss of approximately $2.7 million on the sale of a portion of our auction rate securities in the first quarter of 2012, and the bargain purchase gain of approximately $4.0 million recorded on the acquisition of Frontier-Kemper in the third quarter of 2011.  Interest expense increased by $6.7 million from $26.0 million during the nine months ended September 30, 2011 to $32.7 million during the same period in 2012 due primarily to interest expense on our term loan which was entered into in August 2011.  We had an income tax benefit of $8.9 million during the nine months ended September 30, 2012 as compared to an expense of $36.2 million during the same period in 2011.  This change was due primarily to the impairment charge discussed above, which resulted in a $37.4 million reduction in our provision for income taxes in 2012.  We anticipate our effective tax rate to approximate 3.9% for the remainder of 2012, primarily due to the impairment charge.

Liquidity and Capital Resources

Cash and Working Capital

At September 30, 2012 and December 31, 2011, cash held by us and available for general corporate purposes was $70.1 million and $109.2 million, respectively.  Our proportionate share of cash held by joint ventures and available only for joint venture-related uses, including distributions to joint venture partners, was $110.7 million and $95.1 million at September 30, 2012 and December 31, 2011, respectively, and our restricted cash was $38.7 million and $35.4 million at September 30, 2012 and December 31, 2011, respectively. We do not believe that it is likely we will be called upon to contribute significant additional capital in the event of default by any of our partners.

58

We require each partner in the joint ventures in which we participate to accept joint and several responsibility for all obligations of the joint venture.  Prior to forming a joint venture, we conduct a thorough analysis of the prospective partner to determine its capabilities, specifically relating to construction expertise, track record for delivering a quality product on time, reputation in the industry, as well as financial strength and available liquidity.  We utilize a number of resources to verify a potential joint venture partner’s financial condition, including credit rating reports and financial information contained in its audited financial statements.  We specifically review a potential partner’s available liquidity and bonding capacity.  In the event we are concerned with the financial viability of a potential partner, we will require substantial initial cash contributions upon inception of the joint venture to mitigate the risk that we would be required to cover a disproportionate share of the joint venture’s future cash needs.

The majority of our joint venture contracts are for various government agencies that typically require the joint venture and/or our partners to complete a thorough pre-qualification process.  This pre-qualification process typically includes the verification of each partner’s financial condition and capacity to perform the work, as well as the issuance of performance bonds by surety companies who also independently verify each partner’s financial condition.

A summary of cash flows for each of the nine months ended September 30, 2012 and 2011 is set forth below:

	Nine Months Ended September 30,
(in millions)	2012			2011
Cash flows from:
Operating activities	$	(27.9	)	$	(125.0	)
Investing activities		(9.2	)		(370.8	)
Financing activities		13.7			297.7
Net decrease in cash		(23.4	)		(198.1	)
Cash at beginning of year		204.2			471.4
Cash at end of period	$	180.8		$	273.3

During the nine months ended September 30, 2012, we used $27.9 million in cash to fund operating activities, primarily due to the timing of collections in the Building segment and cash payments for interest on our outstanding debt and income taxes.  We used $9.2 million in cash from investing activities, due primarily to purchase construction equipment, offset by the proceeds from the sales of several of our auction rate securities and construction equipment. We received $13.7 million in cash from financing activities, primarily due to borrowings under our revolving facility offset by cash used for scheduled debt repayments and business acquisition related payments.

At September 30, 2012, we had working capital of $638.7 million, a ratio of current assets to current liabilities of 1.48 to 1.00, and a ratio of long-term debt to equity of 0.58 to 1.00 as compared to working capital of $556.8 million, a ratio of current assets to current liabilities of 1.40 to 1.00 and a ratio of long-term debt to equity of 0.44 to 1.00 at December 31, 2011.  Our stockholders’ equity decreased to $1.1 billion as of September 30, 2012, compared to $1.4 billion as of December 31, 2011.  The increase in our long-term debt to equity ratio and the decrease in our stockholders’ equity at September 30, 2012 primarily reflect the impact of the $376.6 million goodwill and intangible asset impairment charge ($339.2 million after tax) recorded during the nine months ended September 30, 2012.

Long-term Investments

At September 30, 2012, we had investments in auction rate securities (“ARS”) of $46.3 million, which are reflected at fair value. Our investment policy is to manage our assets to achieve our goals of preserving principal, maintaining adequate liquidity at all times, and maximizing returns subject to our investment guidelines. The current overall liquidity concerns in capital markets have affected our ability to liquidate many of our investments in ARS. As such, we classified our ARS as “available-for-sale” Long-term Investments.  Based on our ability to access our cash equivalent investments and our available revolving facility, we do not expect that the short-term lack of liquidity of our ARS investments will materially affect our overall liquidity position or our ability to execute our current business plan.  During the nine months ended September 30, 2012, we received approximately $16.6 million in proceeds from the sale of certain of our ARS holdings.  For a description of our accounting for our ARS, see Note 5 – Fair Value Measurements to Consolidated Condensed Financial Statements.

59

Long-term Debt

On August 2, 2012, we entered into a First Amendment (the “First Amendment”) to its Fifth Amended and Restated Credit Agreement (the “Credit Agreement”) entered into on August 3, 2011 as Borrower, with Bank of America, N.A., as Administrative Agent, Swing Line Lender and L/C Issuer (the “Lender”).  The First Amendment modifies the financial covenants under the Credit Agreement to allow for more favorable minimum net worth, minimum fixed charge and maximum leverage ratios for us and also to add several new financial covenants including minimum liquidity and a consolidated senior leverage ratio.  The First Amendment also increases the sublimit for letters of credit from $50 million to $150 million.

Under the First Amendment, the minimum net worth covenant is modified such that the consolidated net worth cannot be less than the sum of: (i) 85% of the consolidated net worth as of March 31, 2012 less the actual goodwill and intangible assets impairment charge taken on or before September 30, 2012, not to exceed $450.0 million; (ii) an amount equal to 50% of net income for each fiscal quarter ending after June 30, 2012 (with no deduction for net losses); and (iii) an amount equal to 100% of the aggregate amount of all equity issuances after June 30, 2012 that increase stockholder’s equity.  The minimum fixed charge ratio covenant is modified such that the minimum fixed charge ratio shall not be less than 1.00 to 1.00 for the quarterly periods ending September 30, 2012 and December 31, 2012, 1.10 to 1.00 for the quarterly periods ending March 31, 2013 and June 30, 2013, and 1.25 to 1.00 for the quarterly periods ending September 30, 2013 and thereafter.  The consolidated leverage ratio covenant is modified such that the consolidated leverage ratio shall not be greater than 4.25 to 1.00 for the quarterly periods ending September 30, 2012 through March 31, 2013, 3.75 to 1.00 for the quarterly periods ending June 30, 2013 through December 31, 2013, 3.25 to 1.00 for the quarterly periods ending March 31, 2014 through September 30, 2014 and 2.75 to 1.00 for the quarterly periods ending December 31, 2014 and thereafter.  The First Amendment allows for an add-back to EBITDA of up to $ 450.0 million for any goodwill and intangible asset impairment charges that impact the ratios for all fiscal quarters through March 31, 2013.

The First Amendment also modifies the applicable interest rates for amounts outstanding under the credit facility as well as the quarterly fees per annum for the unused portion of the credit facility.  As of the filing date of this Form 10-Q, we are in compliance and expect to continue to be in compliance with the modified financial covenants under the First Amendment.

We had $70.0 million in outstanding borrowings under our revolving facility as of September 30, 2012, and we utilized the revolving facility for outstanding letters of credit in the amount of $0.2 million.  Accordingly, at September 30, 2012, we had $229.8 million available to borrow under our credit agreement.  We believe that our financial position and credit arrangements are sufficient to support our current backlog and anticipated new work.

Long-term debt, excluding current maturities of $63.8 million, was $636.9 million at September 30, 2012, an increase of $24.4 million from $612.5 million at December 31, 2011 primarily due to outstanding borrowings on our revolving facility.  Our long-term debt to equity ratio increased to 0.58 at September 30, 2012, from 0.44 at December 31, 2011, primarily due to our goodwill and intangible asset impairment charge recorded during the period.

There were no other material changes in our contractual obligations as of September 30, 2012.

60

Off-Balance Sheet Arrangements

We do not have any financial partnerships with unconsolidated entities, such as entities often referred to as structured finance, special purpose entities or variable interest entities which are often established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. Accordingly, we are not exposed to any financing, liquidity, market or credit risk that could arise if we had such relationships.

Dividends

There were no cash dividends declared or paid on our outstanding common stock during the nine months ended September 30, 2012.

Forward-looking Statements

The statements contained in this Management’s Discussion and Analysis of the Consolidated Condensed Financial Statements on Form 10-Q that are not purely historical are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, including without limitation, statements regarding our management’s expectations, hopes, beliefs, intentions or strategies regarding the future.  These forward-looking statements are based on our current expectations and beliefs concerning future developments and their potential effects on us.  There can be no assurance that future developments affecting us will be those that we have anticipated.  These forward-looking statements involve a number of risks, uncertainties (some of which are beyond our control) or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by such forward-looking statements. These risks and uncertainties include, but are not limited to:

· our ability to win new contracts and convert backlog into revenue;

· our ability to successfully and timely complete construction projects;

· our ability to realize the anticipated economic and business benefits of our acquisitions and our strategy to assemble and operate a Specialty Contractors business segment;

· the potential delay, suspension, termination or reduction in scope of a construction project;

· the continuing validity of the underlying assumptions and estimates of total forecasted project revenues, costs and profits and project schedules;

· the outcomes of pending or future litigation, arbitration or other dispute resolution proceedings;

· the availability of borrowed funds on terms acceptable to us;

· the ability to retain certain members of management;

· the ability to obtain surety bonds to secure our performance under certain construction contracts;

· possible labor disputes or work stoppages within the construction industry;

· changes in federal and state appropriations for infrastructure projects and the impact of changing economic conditions on federal, state and local funding for infrastructure projects;

· possible changes or developments in international or domestic political, social, economic, business, industry, market and regulatory conditions or circumstances;

· actions taken or not taken by third parties including our customers, suppliers, business partners, and competitors and legislative, regulatory, judicial and other governmental authorities and officials; and

· other risks and uncertainties discussed under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2011 filed with the Securities and Exchange Commission on March 2, 2012.

We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws.

61

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

There has been no material change in our exposure to market risk from that described in Item 7A of our Annual Report on Form 10-K for the year ended December 31, 2011, filed with the Securities and Exchange Commission on March 2, 2012.

Item 4.  Controls and Procedures

Disclosure Controls and Procedures

As required by Rule 13a-15(b) under the Securities Exchange Act of 1934 (the “Exchange Act”), as of the end of the period covered by this report, we carried out an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). In designing and evaluating our disclosure controls and procedures, we recognize that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and our management necessarily was required to apply its judgment in evaluating and implementing possible controls and procedures. The effectiveness of our disclosure controls and procedures is necessarily limited by the staff and other resources available to us and, although we have designed our disclosure controls and procedures to address the geographic diversity of our operations, this diversity inherently may limit the effectiveness of those controls and procedures. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Controls Over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the period covered by this report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.  As part of our integration of our recent acquisitions, we have substantially completed the process of incorporating our controls and procedures into the operations of these newly acquired entities.

In connection with Rule 13a-15(b) under the Securities Exchange Act of 1934, we will continue to review and assess the adequacy of our disclosure controls and procedures, including our internal control over financial reporting, and may from time to time make changes aimed at enhancing their effectiveness and to ensure that our systems evolve with our business.

Part II. - Other Information

Item 1. Legal Proceedings

From time to time in the ordinary course of business, we are subject to claims, asserted or unasserted, or named as a party to lawsuits or investigations.  Litigation can be expensive and disruptive to normal business operations.  Moreover, the results of legal proceedings cannot be predicted with any certainty and, in the case of more complex legal proceedings, the results are difficult to predict at all.  We disclosed information about certain of our legal proceedings in Part I, Item 3 of our Annual Report on Form 10-K for the year ended December 31, 2011. For an update to those disclosures, see Note 7 -Contingencies and Commitments to Consolidated Condensed Financial Statements.

62

Item 1A.  Risk Factors

Information regarding risk factors affecting our business is discussed in our Annual Report on Form 10-K for the year ended December 31, 2011.  There have been no material changes from those risk factors during the nine months ended September 30, 2012.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

There were no repurchases by the Company of its equity securities during the nine months ended September 30, 2012.  The Company acquired 19,657 shares from several employees in connection with the settlement of income tax and related benefit withholding obligations arising from vesting in restricted stock units.

Item 3. Defaults Upon Senior Securities

None.

Item 4. Mine Safety Disclosures

Section 1503 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) requires domestic mine operators to disclose violations and orders issued under the Federal Mine Safety and Health Act of 1977 (the “Mine Act”) by the federal Mine Safety and Health Administration.  We do not act as the owner of any mines but we may act as a mining operator as defined under the Mine Act where we may be an independent contractor performing services or construction of such mine.

Information concerning mine safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank Act and Item 104 Regulation S-K is included in Exhibit 95.

Item 5. Other Information

None.

Exhibit 31.1

CERTIFICATION OF PRINCIPAL EXECUTIVE OFFICER PURSUANT TO SECTION 302

OF THE SARBANES-OXLEY ACT OF 2002

I, Ronald N. Tutor, certify that:

1. I have reviewed this quarterly report on Form 10-Q of Tutor Perini Corporation (the “registrant”);

2. Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements made, in light of the circumstances under which such statements were made, not misleading with respect to the period covered by this report;

3. Based on my knowledge, the financial statements, and other financial information included in this report, fairly present in all material respects the financial condition, results of operations and cash flows of the registrant as of, and for, the periods presented in this report;

4. The registrant’s other certifying officer and I are responsible for establishing and maintaining disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the registrant and have:

(1) Cash, cash equivalents and restricted cash consist primarily of money market funds with original maturity dates of three months or less, for which fair value is determined through quoted market prices.

(2) Short-term investments are classified as other current assets and are comprised of municipal bonds, the majority of which are rated Aa2 or better. The fair values of the municipal bonds are obtained from readily-available pricing sources for comparable instruments, and as such, the Company has classified these assets as Level 2.

(3) Bonds substituted for retainage are classified as accounts receivable, including retainage and are comprised of U.S. Treasury Notes and other municipal bonds, the majority of which are rated Aa3 or better. The fair values of these assets are obtained from readily-available pricing sources for comparable instruments, and as such, the Company has classified these assets as Level 2.

(4) At September 30, 2012 the Company had $46.3 million invested in auction rate securities ("ARS") which the Company considers as available-for-sale long-term investments. The long-term investments ARS held by the Company at September 30, 2012 are in securities collateralized by student loan portfolios. At September 30, 2012 most of the Company's ARS were rated AAA and AA+. The Company estimated the fair value of its ARS utilizing an income approach valuation model which considered, among other items, the following inputs: (i) the underlying structure of each security; (ii) the present value of future principal and interest payments discounted at rates considered to reflect current market conditions (discount rates range from 3% to 7%); (iii) consideration of the probabilities of default or repurchase at par for each period (term periods range from 6 to 8 years); (iv) prices from recent comparable transactions; and (v) other third party pricing information without adjustment. See the Level 3 ARS rollforward below for disclosure of the Company's valuation approach.

(5) As discussed in Note 10 – Financial Commitments, the Company entered into a swap agreement with Bank of America, N.A. to establish a long-term interest rate for its $200 million five-year term loan. The swap agreement became effective for the term loan principal balance outstanding at January 31, 2012 and will remain effective through the maturity date of the term loan. The Company values the interest rate swap liability utilizing a discounted cash flow model that takes into consideration forward interest rates observable in the market and the counterparty's credit risk. This liability is classified as a component of other long-term liabilities.

(6) The liabilities listed as of September 30, 2012 above represent the contingent consideration for the Company's recent acquisitions for which the measurement period for purchase price analysis has concluded. See the Level 3 contingent consideration rollforward below for disclosure of the Company's valuation approach.

For the three and nine months ended September 30, 2012, the Company recognized $1.8 million and $5.6 million, respectively, of compensation expense related to restricted stock awards. As of September 30, 2012 there was $6.5 million of unrecognized compensation cost related to the unvested awards which, absent significant forfeitures in the future, is expected to be recognized over a weighted average period of approximately 2.6 years. A summary of restricted stock awards activity under the Plan for the nine months ended September 30, 2012 is as follows:

	Number of Shares			Weighted Average Grant Date Fair Value		Aggregate Intrinsic Value

Key assumptions used in determining fair value of awards

During 2009, the Compensation Committee approved the award of 750,000 stock options that vest in five equal annual tranches from 2010 to 2014 subject to the achievement of pre-tax income performance targets established by the Compensation Committee. In March 2012, the Compensation Committee established the 2012 pre-tax income performance target for the fourth tranche of 150,000 stock options awarded in 2009. During May 2012, the Compensation Committee approved the award of 15,000 stock options that vest subject to service-based requirements only. The fair values of these stock options were determined during the nine months ended September 30, 2012 based on the Black Scholes option pricing model using the following key assumptions:

Number of Shares		150,000		15,000
Risk-free interest rate		0.88%		1.12%
Expected life of options	4.4 years		7.3 years
Expected volatility of underlying stock		53.89%		50.59%
Expected quarterly dividends (per share)		0.00		0.00

Income Taxes [Abstract]

Income Taxes

(8) Income Taxes

The Company's effective tax rate for the nine months ended September 30, 2012 and 2011 was 3.9% and 36.8%, respectively. The effective tax rate for the nine months ended September 30, 2012 excludes $3.6 million of certain discrete expense items related to an increase in unrecognized tax benefits of $1.1 million and an adjustment of $2.5 million, both associated with certain stock-based compensation items identified in March 2012. Other discrete items include $4.9 million related to the change in the Company's forward looking state rate and $0.9 million of benefits claimed on the tax return in excess of the prior year's income tax provision, offset by $5.0 million of additional tax benefits derived from purchased entities and a $1.0 million reversal of tax reserves. The Company's provision for income taxes and effective tax rate for the nine months ended September 30, 2012 were significantly impacted by the goodwill and intangible asset impairment charge discussed in Note 6 – Goodwill and Intangible Assets above. Of the total goodwill and intangible asset impairment charge of $376.6 million, approximately $255.0 million pertained to goodwill or intangible assets that yielded permanent differences between book income and taxable income. The Company has tax effected the impairment charge for the current year-to-date period based on its estimated annual effective tax rate of 3.9%, which resulted in a reduction in its provision for income taxes of approximately $37.4 million during the period. Additionally, approximately $47.7 million was recorded as a reduction in previously recorded deferred tax liabilities due to the impairment charge.

For financial statement purposes the Company uses the more-likely-than-not recognition threshold and a tax benefit measurement process for recording changes to unrecognized tax benefits. The Company recognizes interest and penalties on any income tax liabilities as a component of its income tax provision. The total amount of gross unrecognized tax benefits recorded was approximately $2.0 million and $1.7 million as of September 30, 2012 and December 31, 2011, respectively.

The Company's 2010 U.S. Federal tax return is currently being audited by the Internal Revenue Service.

Stock-Based Compensation [Abstract]

Stock-Based Compensation

(9) Stock-Based Compensation

The Tutor Perini Long-Term Incentive Plan (the "Plan") allows the Company to grant stock-based compensation awards in a variety of forms including restricted stock and stock options. The terms and conditions of the awards granted are established by the Compensation Committee of the Company's Board of Directors, who administers the Plan.

For the three and nine month periods ended September 30, 2012, the Company recognized total stock-based compensation expense of $2.3 million and $7.4 million, respectively, in general and administrative expenses For the three and nine month periods ended September 30, 2011, the Company recognized a credit of $0.3 million and total stock-based compensation expense of $6.8 million, respectively, in general and administrative expenses.

Restricted Stock Awards

Restricted stock awards vest subject to the satisfaction of service requirements or the satisfaction of both service requirements and achievement of certain performance targets. Upon vesting, each award is exchanged for one share of the Company's common stock. The grant date fair values of these awards are determined based on the closing price of the Company's common stock on either the award date (if subject only to service conditions), or the date that the Compensation Committee establishes the applicable performance target (if subject to performance conditions). As of September 30, 2012, the Compensation Committee has approved the grant of an aggregate of 4,875,833 restricted stock awards to eligible participants.

In March 2012, the Compensation Committee established the 2012 pre-tax income performance targets for 220,000 restricted stock units awarded in 2009 and 2010. In May and June 2012, the Compensation Committee approved the award of 783,333 new restricted stock units. Additionally, 120,833 restricted stock units were forfeited during the nine months ended September 30, 2012.

For the three and nine months ended September 30, 2012, the Company recognized $1.8 million and $5.6 million, respectively, of compensation expense related to restricted stock awards. As of September 30, 2012 there was $6.5 million of unrecognized compensation cost related to the unvested awards which, absent significant forfeitures in the future, is expected to be recognized over a weighted average period of approximately 2.6 years. A summary of restricted stock awards activity under the Plan for the nine months ended September 30, 2012 is as follows:

	Number of Shares			Weighted Average Grant Date Fair Value		Aggregate Intrinsic Value
Granted and Unvested - January 1, 2012		1,185,832		$	19.65	$	14,633,167
Vested		(208,332	)	$	24.36		2,626,729
Granted		293,333		$	14.39		3,355,730
Forfeited		(120,833	)	$	13.47		-
Total Granted and Unvested		1,150,000		$	18.10		13,156,000
Approved for grant		888,335		(a)			10,162,552
Total Awarded and Unvested – September 30, 2012		2,038,335		n.a.			23,318,552

(a) Grant date fair value cannot be determined currently because the related performance targets for future years have not yet been established by the Compensation Committee.

The outstanding unvested awards at September 30, 2012 are scheduled to vest as follows, subject where applicable to the achievement of performance targets. As described above, certain performance targets have not yet been established.

Vesting Date	Number of Awards
2013	905,000
2014	408,335
2015	150,000
2016	165,000
2017	410,000
Total	2,038,335

Approximately 245,000 of the unvested awards will vest based on the satisfaction of service requirements and 1,793,335 will vest based on the satisfaction of both service requirements and the achievement of certain performance targets.

Stock Options

Stock option awards generally vest subject to the satisfaction of service requirements or the satisfaction of both service requirements and achievement of certain performance targets. The grant date fair values of these awards are determined based on the Black-Scholes option price model on either the award date (if subject only to service conditions), or, the date that the Compensation Committee establishes the applicable performance target (if subject to performance conditions). The related compensation expense is amortized over the applicable requisite service period. The exercise price of the options is equal to the closing price of the Company's common stock on the date the awards were approved by the Compensation Committee, and the awards expire ten years from the award date. As of September 30, 2012, the Compensation Committee has approved an aggregate of 2,380,465 stock option awards to eligible participants.

In March 2012 the Compensation Committee established the 2012 pre-tax income performance target for 150,000 stock options awarded in 2009. In May and June 2012 the Compensation Committee approved the award of 695,000 new stock options. Additionally, 75,000 stock options were forfeited during the nine months ended September 30, 2012.

For the three and nine months ended September 30, 2012, the Company recognized compensation expense of $0.5 million and $1.9 million, respectively, related to stock option awards. As of September 30, 2012, there was $2.4 million of unrecognized compensation expense related to the outstanding options which, absent significant forfeitures in the future, is expected to be recognized over a weighted average period of approximately 2.7 years.

A summary of stock option activity under the Plan for the nine months ended September 30, 2012 is as follows:

				Weighted Average
	Number of Shares			Grant Date Fair Value		Exercise Price
Total Granted and Outstanding - January 1, 2012		1,225,465		$	10.11	$	18.45
Granted		165,000		$	5.65	$	19.51
Forfeited		(75,000	)	$	7.20	$	-
Total Granted and Outstanding		1,315,465		$	9.72	$	18.91

Total Awarded and Outstanding – September 30, 2012		2,145,465		n.a.		$	16.55

(a) Grant date fair value cannot be determined currently because the related performance targets for future years have not yet been established by the Compensation Committee.

There were 490,465 options that have vested and were exercisable at September 30, 2012 at a weighted average exercise price of $19.79 per share. Of the remaining options outstanding, approximately 592,500 will vest based on the satisfaction of service requirements and 1,062,500 will vest based on the satisfaction of both service requirements and the achievement of certain performance targets.

At September 30, 2012, the outstanding options of 1,315,465 shares had an intrinsic value of $0.1 million and a weighted average remaining contractual life of 6.8 years.

During 2009, the Compensation Committee approved the award of 750,000 stock options that vest in five equal annual tranches from 2010 to 2014 subject to the achievement of pre-tax income performance targets established by the Compensation Committee. In March 2012, the Compensation Committee established the 2012 pre-tax income performance target for the fourth tranche of 150,000 stock options awarded in 2009. During May 2012, the Compensation Committee approved the award of 15,000 stock options that vest subject to service-based requirements only. The fair values of these stock options were determined during the nine months ended September 30, 2012 based on the Black Scholes option pricing model using the following key assumptions:

Number of Shares		150,000		15,000
Risk-free interest rate		0.88%		1.12%
Expected life of options	4.4 years		7.3 years

Mergers and Acquisitions

(3) Mergers and Acquisitions

(a) Information regarding acquisitions that are material in the aggregate

On January 3, 2011, the Company completed the acquisition of Fisk Electric Company ("Fisk"), a privately held electrical construction company based in Houston, Texas. Fisk was acquired because the Company believes that it is a strong strategic fit enabling the Company to expand its nationwide electrical construction capabilities and to realize significant synergies and opportunities in support of the Company's non-residential building and civil operations. On April 1, 2011, the Company completed the acquisition of Anderson Companies ("Anderson"), the privately held parent company of Roy Anderson Corporation, Harrell Contracting Group, LLC and Brice Building Company, LLC. Anderson was acquired because the Company believes that it is a strong strategic fit for the Company's building business and strengthens the Company's position in the southeastern United States. On June 1, 2011, the Company completed the acquisition of Frontier-Kemper Constructors, Inc. ("Frontier-Kemper"), a privately held Indiana-based corporation. Frontier-Kemper was acquired because the Company believes that it is a strong strategic fit for the Company's civil business, bolstering the Company's tunneling business in the United States and expanding the Company's geographic reach into Canada. On August 18, 2011, the Company completed the acquisition of Becho, Inc. ("Becho"), a privately held Utah-based corporation. Becho was acquired because the Company believes that it is a strong strategic fit for the Company's civil business, bolstering the Company's drilling capabilities in the southwestern United States.

The transactions were accounted for using the acquisition method of accounting. During the nine months ended September 30, 2012, the Company did not materially revise any of the assumptions, estimates or amounts used to complete its purchase price accounting as of December 31, 2011.

The following unaudited pro forma summary financial information presents the operating results of the combined Company for the three months and nine months ended September 30, 2011 assuming that the acquisitions occurred on January 1, 2010. This unaudited pro forma summary financial information is presented for informational purposes only and is not indicative either of the operating results that actually would have occurred had the acquisitions been completed on January 1, 2010, or of future results.

(c) Acquisition of Lunda Construction Company

On July 1, 2011, the Company completed the acquisition of Lunda Construction Company ("Lunda"). Headquartered in Black River Falls, Wisconsin, and with offices in Wisconsin and Minnesota, Lunda is a heavy civil contractor engaged in the construction, rehabilitation and maintenance of bridges, railroads, and other civil structures in the Midwest and throughout the United States. Lunda was acquired because the Company believes it is a strong strategic fit for its civil business and will provide the Company with the opportunity to expand its civil business into the Midwestern United States.

The transaction was accounted for using the acquisition method of accounting. During the nine months ended September 30, 2012, the Company did not materially revise any of the assumptions, estimates or amounts used to complete its purchase price accounting as of December 31, 2011.

The following unaudited pro forma summary financial information presents the operating results of the combined Company for the three months and nine months ended September 30, 2011 assuming that the acquisition occurred on January 1, 2010.

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, 2011. During the nine months ended September 30, 2012, the Company adopted the following accounting pronouncements that were issued in 2011:

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. Other than requiring additional disclosures, adoption of this update has not had 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. The adoption of this update has not had 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 that adopts this option 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. On January 1, 2012, the Company adopted this option. The adoption of this option has not had a material effect on the Company's consolidated financial statements, but it may impact the manner in which the Company performs testing for goodwill impairment.

In July 2012, the FASB issued a staff position that gives an entity the option to make a qualitative evaluation about the likelihood of indefinite-lived intangible asset impairment. An entity that adopts this option will be required to perform the quantitative test only if it concludes that the fair value of the indefinite-lived intangible asset is more likely than not less than its carrying value. The effective date is for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. The Company does not expect the adoption of this option to have a material effect on the Company's consolidated financial statements, but it may impact the manner in which the Company performs testing for indefinite-lived intangible asset impairment.

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, 2012 and December 31, 2011, consisted of the following (in thousands):

	September 30, 2012		December 31, 2011
Unbilled costs and profits incurred to date*	$	141,980	$	107,645
Unapproved change orders		107,786		136,704
Claims		161,896		114,049
	$	411,662	$	358,398

* 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, 2012 and December 31, 2011, approximately $72.2 million and $85.2 million, respectively, are amounts subject to pending litigation or dispute resolution proceedings as described in Note 7 – Contingencies and Commitments. 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.

The Company recognizes revenues from its contracts under the percentage of completion method. In the ordinary course of business, and at a minimum on a quarterly basis, the Company updates projected total contract revenue, cost and profit or loss for each of our contracts based on changes in facts, such as an approved scope change, and changes in estimates. During the three 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 as discussed in Note 8 –Income Taxes, this change in estimate resulted in a $12.4 million increase in income from construction operations, a $7.2 million increase in net income and a $0.15 increase in diluted earnings per common share during the three and nine months ended September 30, 2012. This change was the only change in estimate considered material to the Company's results of operations during the periods presented herein.

Amended Credit Agreement

On August 2, 2012, the Company entered into a First Amendment (the "First Amendment") to its Fifth Amended and Restated Credit Agreement (the "Credit Agreement") entered into on August 3, 2011 as Borrower, with Bank of America, N.A., as Administrative Agent, Swing Line Lender and L/C Issuer (the "Lender"). The First Amendment modifies the financial covenants under the Credit Agreement beginning for the period ended September 30, 2012 to allow for more favorable minimum net worth, minimum fixed charge and maximum leverage ratios for the Company and also to add new financial covenants including minimum liquidity and consolidated senior leverage ratio covenants. The First Amendment also increases the sublimit for letters of credit from $50 million to $150 million.

Under the First Amendment, the minimum net worth covenant is modified such that the consolidated net worth of the Company cannot be less than the sum of: (i) 85% of the consolidated net worth as of March 31, 2012 less the actual goodwill and intangible assets impairment charge taken on or before September 30, 2012, not to exceed $450.0 million; (ii) an amount equal to 50% of net income for each fiscal quarter ending after June 30, 2012 (with no deduction for net losses); and (iii) an amount equal to 100% of the aggregate amount of all equity issuances after June 30, 2012 that increase stockholder's equity. The minimum fixed charge ratio covenant is modified such that the minimum fixed charge ratio shall not be less than 1.00 to 1.00 for the quarterly periods ending September 30, 2012 and December 31, 2012, 1.10 to 1.00 for the quarterly periods ending March 31, 2013 and June 30, 2013, and 1.25 to 1.00 for the quarterly periods ending September 30, 2013 and thereafter. The consolidated leverage ratio covenant is modified such that the consolidated leverage ratio shall not be greater than 4.25 to 1.00 for the quarterly periods ending September 30, 2012 through March 31, 2013, 3.75 to 1.00 for the quarterly periods ending June 30, 2013 through December 31, 2013, 3.25 to 1.00 for the quarterly periods ending March 31, 2014 through September 30, 2014 and 2.75 to 1.00 for the quarterly periods ending December 31, 2014 and thereafter. The First Amendment allows for an add-back to EBITDA of up to $450.0 million for any goodwill and intangible asset impairment charges that impact the ratios for all fiscal quarters through March 31, 2013.

The First Amendment also modifies the applicable interest rates for amounts outstanding such that they bear interest at a rate equal to, at the Company's option, (a) the adjusted British Bankers Association LIBOR rate, as defined, plus 200 to 400 basis points (floor of 200 basis points) based on the ratio of consolidated funded indebtedness of the Company and its subsidiaries to consolidated EBITDA or (b) the higher of the Federal Funds Rate plus 50 basis points, or the prime rate announced by Bank of America, N.A., plus up to 300 basis points based on the ratio of consolidated funded indebtedness of the Company and its subsidiaries to consolidated EBITDA. In addition, the Company has agreed to pay quarterly facility fees ranging from 0.375% to 0.700% per annum of the unused portion of the credit facility.

The Credit Agreement allows the Company to borrow up to $300 million on a revolving credit basis (the "Revolving Facility"), with a $150 million sublimit for letters of credit, and an additional $200 million term loan (the "Term Loan"). Subject to certain conditions, the Company has the option to increase the base facility by up to an additional $50 million. Substantially all of the Company's subsidiaries unconditionally guarantee the obligations of the Company under the Credit Agreement. The obligations under the Credit Agreement are secured by a lien on all personal property of the Company and its subsidiaries party thereto. Any outstanding loans under the Revolving Facility mature on August 3, 2016, while the Term Loan includes quarterly installments of principal and interest payable over a five-year period. The Term Loan balance has been paid down to $161.3 million at September 30, 2012.

The Company was in compliance with the modified financial covenants under the First Amendment for the period ended September 30, 2012.

The Company had $70.0 million of outstanding borrowings under its Revolving Facility as of September 30, 2012 and no outstanding borrowings as of December 31, 2011. The Company utilized the Revolving Facility for letters of credit in the amount of $0.2 million and $3.0 million as of September 30, 2012 and December 31, 2011, respectively. Accordingly, at September 30, 2012, the Company had $229.8 million available to borrow under the Credit Agreement.

On August 26, 2011, the Company entered into a swap agreement ("Swap Agreement") with Bank of America, N.A. to establish a long-term interest rate for the Term Loan discussed above. The Swap Agreement pertains to the Term Loan principal balance outstanding at January 31, 2012 and will remain effective through the maturity date of the Term Loan. Amounts outstanding under the Swap Agreement will bear interest at a rate equal to the Applicable Rate, as defined in the Credit Agreement (based upon the Company's consolidated leverage ratio), plus 97.5 basis points. The Swap Agreement includes quarterly installments of principal and monthly installments of interest payable through the maturity date of the Term Loan.

Goodwill and Intangible Assets [Abstract]

Goodwill and Intangible Assets

(6) Goodwill and Intangible Assets

The Company tests goodwill and intangible assets with indefinite lives for impairment by applying a fair value test in the fourth quarter of each year and between annual tests if events occur or circumstances change which suggest that the goodwill or intangible assets should be evaluated. Intangible assets with finite lives are also tested for impairment whenever events or circumstances indicate that the carrying value may not be recoverable. During the second quarter of 2012, the Company experienced a sustained decrease in its stock price, causing its market capitalization to be substantially less than its carrying value and its implied control premium to increase beyond the implied control premium that was reconciled in its 2011 annual impairment analysis, and beyond the observable market comparable level. Additionally, deterioration in broader market conditions including stock market volatility, particularly in the construction industry, impacted the weighted average cost of capital rate assumptions used in deriving the fair values of the Company's reporting units, which are based primarily on market inputs. Finally, several of the Company's reporting units experienced degradation in the timing of projected cash flows used in deriving the fair values of those reporting units in its 2011 annual impairment analysis caused by delays in the timing of awards and start of new work that the Company anticipated would enter into backlog in the first half of 2012, and a general decrease in profit margins on new work awards that were factored into the Company's forecast assumptions.

In the Building reporting unit, the most significant decrease in estimated new work cash flow was the result of political decisions that negatively impacted the advance of a large project for an existing customer. In addition, the Company observed an unfavorable change in the margin mix of new work obtained in the first half of 2012 compared with prior years. The majority of the new work awards in the first half of 2012 as well as the near term new work prospects were comprised of lower margin private client work and not the higher margin public works the Building reporting unit completed in the past. The projected cash flows for the Building reporting unit as of June 30, 2012 took into consideration the changes in assumptions on new work awards and unfavorable change in margin mix, consistent with its actual results in the first half of 2012.

In the Civil reporting unit, the fourth quarter of 2011 valuation anticipated the award and start and/or ramp-up of a number of projects during 2012. Many of these projects were delayed for several reasons including political pressures, timing of funding, and general economic concerns. The change in the estimated timing of recent awards and resulting ramp-up of production resulted in deterioration in anticipated future cash flows from fourth quarter of 2011 expectations. The projected cash flows for the Civil reporting unit as of June 30, 2012 took into consideration the change in estimated timing of award and ramp-up of new work.

Within the Management Services reporting unit valuation for the fourth quarter of 2011, cash flow projections included the anticipated ramp-up of work associated with the movement of Pacific Marine Corps operations from the island of Okinawa to the island of Guam. During April 2012, United States bipartisan legislators were unable to come to agreement on government spending cuts and certain government projects were suspended. This left doubt around the timing and magnitude of the proposed move. The projected cash flows for the Management Services reporting unit as of June 30, 2012 took into consideration the uncertainty of timing surrounding significant projects with the Pacific Marine Corps on the island of Guam.

Based on these circumstances and events, the Company performed an interim goodwill and indefinite lived intangible asset impairment test as of June 30, 2012 and, as a result, the Company recorded a goodwill impairment charge of $321.1 million and an indefinite lived intangible assets impairment charge of $16.4 million in the second quarter of 2012. The Company also evaluated its finite lived tangible and intangible assets due to the degradation in the timing of projected cash flows since the Company's 2011 impairment analysis and changes in the planned use of certain intangible assets, and this analysis resulted in a $39.1 million impairment charge on the Company's finite lived intangible assets in the second quarter of 2012. These non-cash charges did not impact the Company's overall business operations.

The first step in the two-step process of the impairment analysis was to determine the fair value of the Company and each of its reporting units and compare the fair value of each reporting unit to its carrying value. If the carrying value of the reporting unit exceeded its fair value, a second step was followed to calculate the goodwill impairment. The second step involved determining the fair value of the individual assets and liabilities of the reporting unit that failed the first step and calculating the implied fair value of goodwill. To determine the fair value of the Company and each of its reporting units, the Company utilized both an income-based valuation approach as well as a market-based valuation approach. The income-based valuation approach was based on the cash flows that the reporting unit expected to generate in the future and required the Company to project revenues, operating expenses, working capital investment, capital spending and cash flows for the reporting unit in a discrete period, as well as to determine the weighted average cost of capital to be used as a discount rate and a terminal value growth rate for the non-discrete period. The market-based valuation approach to estimate the fair value of the Company's reporting units utilized industry multiples of revenues and operating earnings. The Company equally weighted the fair values calculated under the income-based and market-based valuation approaches in arriving at the concluded fair values of its reporting units.

As part of the valuation process, the aggregate fair value of the Company was compared to its market capitalization at the valuation date in order to determine the implied control premium. The implied control premium was then compared to the control premiums paid in recent transactions within the industry. The Company's implied market control premium of 78.1% and 42.5%, as of the fourth quarter of 2011 and the second quarter of 2012 valuation, respectively, were determined to be in an acceptable range of market transactions observed in the construction and engineering industry in the past seven years.

As part of the review process for the reporting unit valuations, the Company created multiple income-based and market-based valuation models to understand the sensitivity of the variables used in determining the fair value. These models were reviewed with the Company's external fair value specialists who assisted in the process by providing insight into acceptable ranges on various valuation assumptions as well as preferred valuation techniques.

Impairment assessment inherently involves management judgments as to the assumptions used to project these amounts and the impact of market conditions on those assumptions. The key assumptions that the Company used to estimate the fair value of its reporting units under the income-based approach were as follows:

· Weighted average cost of capital used to discount the projected cash flows;

· Cash flows generated from existing and new work awards; and

· Projected operating margins.

Weighted average cost of capital rates used to discount the projected cash flows were developed via the capital asset pricing model which is primarily based upon market inputs. The Company used discount rates that management felt were an accurate reflection of the risks associated with the forecasted cash flows of its respective reporting units. Weighted average cost of capital inputs ranged from 15% - 16.5% for the Company's reporting units. As discussed above, since the Company's 2011 annual impairment analysis, the weighted average cost of capital rates were impacted by broader market conditions including the recent stock market volatility, particularly in the construction industry.

To develop the cash flows generated from new work awards and future operating margins, the Company tracked prospective work for each of its reporting units primarily on a project-by-project basis as well as the estimated timing of when the work would be bid or prequalified, started and completed. The Company also gave consideration to its relationships with the prospective owners, the pool of competitors that were capable of performing large, complex work, changes in business strategy, and the Company's history of success in winning new work in each reporting unit. With regard to operating margins, the Company gave consideration to its historical reporting unit operating margins in the end markets that the prospective work opportunities were most significant, current market trends in recent new work procurement, and changes in business strategy.

Similar to previous valuations, the Company noted that small changes to valuation assumptions could have a significant impact on the concluded value; however, the Company gained comfort over the assumptions selected for valuation through comparison to historical transaction benchmarks, third party industry expectations, and the Company's previous models.

The Company also estimated the fair value of its reporting units under a market-based approach by applying industry-comparable multiples of revenues and operating earnings to its reporting units' projected performance. The conditions and prospects of companies in the construction industry depend on common factors such as overall demand for services.

Changes in the Company's assumptions or estimates could materially affect the determination of the fair value of a reporting unit. Such changes in assumptions could be caused by:

· Terminations, suspensions, reductions in scope or delays in the start up of the revenues and cash flows from backlog as well as the prospective work tracked;

· Reductions in available government, state and local agencies and non-residential private industry funding and spending;

· The Company's ability to effectively compete for new work and maintain and grow market penetration in the regions that the Company operates in;

· The Company's ability to successfully control costs, work schedule, and project delivery; or

· Broader market conditions, including stock market volatility in the construction industry and its impact on the weighted average cost of capital assumption.

With regard to the Company's reporting units, the carrying values of the Company's Building, Civil and Management Services reporting units were greater than their fair values, and as such, the Company performed the second step of the goodwill impairment test for these reporting units which resulted in goodwill impairments as discussed above. In this second step, the Company determined the fair value of the individual assets and liabilities of the reporting units that failed Step 1 and calculated the implied fair value of goodwill for those reporting units. The Company included in this calculation the valuation of assets and liabilities that would occur in a theoretical purchase price allocation of the reporting unit in accordance with the Financial Accounting Standards Board's (the "FASB") Accounting Standards Codification ("ASC") 805 – Business Combinations, as well as the value of backlog, trade name, and customer relationships and the impact of deferred tax liabilities and assets arising from the fair valuation of these assets and liabilities.

The fair value of the Specialty Contractors reporting unit substantially exceeded its carrying value, and as such, it was not necessary to perform the second step of the goodwill impairment test for this reporting unit.

In conducting the initial step of its goodwill evaluation, the Company also evaluated its finite lived tangible and intangible assets due to the degradation in the timing of projected cash flows since the Company's 2011 impairment analysis and changes in the planned use of certain intangible assets. The Company compared the fair value of the finite lived tangible and intangible assets to their carrying value and determined that the carrying value of a portion of these assets exceeded their fair value as determined by the income-based valuation approach and by benchmarking against observable market prices. This income-based valuation approach involved key assumptions similar to those used in the goodwill impairment analysis for the Company's reporting units as discussed above, (e.g. projections of future cash flows associated with the Company's trade name, contractor license, customer relationship and contract backlog intangible assets that were recorded in previous acquisitions). This analysis resulted in an impairment charge of $39.1 million associated with its finite lived intangible assets.

During the third quarter of 2012, the Company completed its evaluation of the key assumptions used in its interim impairment analysis of goodwill and intangible assets with indefinite lives, and concluded that there were no adjustments required to be made to the impairment charges recorded in the second quarter of 2012.

Fair Value Measurements [Abstract]

Fair Value Measurements

(5) Fair Value Measurements

The Company measures certain financial instruments, including cash and cash equivalents, such as money market funds, at their fair values. The fair values were determined based on a three-tier valuation hierarchy for disclosure of significant inputs. These hierarchical tiers are defined as follows:

Level 1 – inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 –inputs are other than quoted prices in active markets that are either directly or indirectly observable through market corroboration.

Level 3 –inputs are unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions based on the best information available in the circumstances.

The following tables provide the assets and liabilities carried at fair value measured on a recurring basis as of September 30, 2012 and December 31, 2011 (in thousands):

(1) Cash, cash equivalents and restricted cash consist primarily of money market funds with original maturity dates of three months or less, for which fair value is determined through quoted market prices.

(2) Short-term investments are classified as other current assets and are comprised of municipal bonds, the majority of which are rated Aa2 or better. The fair values of the municipal bonds are obtained from readily-available pricing sources for comparable instruments, and as such, the Company has classified these assets as Level 2.

(3) Bonds substituted for retainage are classified as accounts receivable, including retainage and are comprised of U.S. Treasury Notes and other municipal bonds, the majority of which are rated Aa3 or better. The fair values of these assets are obtained from readily-available pricing sources for comparable instruments, and as such, the Company has classified these assets as Level 2.

(4) At September 30, 2012 the Company had $46.3 million invested in auction rate securities ("ARS") which the Company considers as available-for-sale long-term investments. The long-term investments ARS held by the Company at September 30, 2012 are in securities collateralized by student loan portfolios. At September 30, 2012 most of the Company's ARS were rated AAA and AA+. The Company estimated the fair value of its ARS utilizing an income approach valuation model which considered, among other items, the following inputs: (i) the underlying structure of each security; (ii) the present value of future principal and interest payments discounted at rates considered to reflect current market conditions (discount rates range from 3% to 7%); (iii) consideration of the probabilities of default or repurchase at par for each period (term periods range from 6 to 8 years); (iv) prices from recent comparable transactions; and (v) other third party pricing information without adjustment. See the Level 3 ARS rollforward below for disclosure of the Company's valuation approach.

(5) As discussed in Note 10 – Financial Commitments, the Company entered into a swap agreement with Bank of America, N.A. to establish a long-term interest rate for its $200 million five-year term loan. The swap agreement became effective for the term loan principal balance outstanding at January 31, 2012 and will remain effective through the maturity date of the term loan. The Company values the interest rate swap liability utilizing a discounted cash flow model that takes into consideration forward interest rates observable in the market and the counterparty's credit risk. This liability is classified as a component of other long-term liabilities.

(6) The liabilities listed as of September 30, 2012 above represent the contingent consideration for the Company's recent acquisitions for which the measurement period for purchase price analysis has concluded. See the Level 3 contingent consideration rollforward below for disclosure of the Company's valuation approach.

Assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the three and nine months ended September 30, 2012 and 2011 are as follows (in thousands):

The Company has classified its ARS investment as long-term investments in the Consolidated Condensed Balance Sheets as the Company believes the market for government-backed student loans may take in excess of twelve months to fully recover.

The Company performs a fair market value assessment of its auction rate securities (ARS) on a quarterly basis. To estimate fair value, the Company utilizes an income approach valuation model, with consideration given to market-based valuation inputs. The model considers, among other items, the following inputs: (i) the underlying structure of each security; (ii) the present value of future principal and interest payments discounted at rates considered to reflect current market conditions (discount rates range from 3% to 7% for investment grade securities); (iii) consideration of the probabilities of default or repurchase at par for each period (term periods range from 6 to 8 years); (iv) prices from recent comparable transactions; and (v) other third party pricing information.

The inputs and the Company's analysis consider: (i) contractual terms of the ARS instruments; (ii) government-backed guarantees, if any; (iii) credit ratings on the ARS; (iv) current interest rates on the ARS and other market interest rate data; (v) trade data available, including trade data from secondary markets, for the Company's ARS or similar ARS; (vi) recovery rates for any non-government guaranteed assets; (vii) historical transactions of the Company's ARS being called at par; (viii) refunding initiatives of ARS; and (ix) risk of downgrade and default. Current market conditions, including repayment status of student loans, credit market risk, market liquidity and macro-economic influences are reflected in these inputs.

On a quarterly basis, the Company also assesses the recoverability of the ARS balance by reviewing: (i) the regularity and timely payment of interest on the securities; (ii) the probabilities of default or repurchase at par; (iii) the risk of loss of principal from government-backed versus non-government-backed securities; and (iv) the prioritization of the Company's tranche of securities within the investment in case of default. The potential impact of any principal loss is included in the valuation model.

When the Company's analysis indicates an impairment of a security, several factors are considered to determine the proper classification of the charge including: (i) any requirement or intent to sell the security; (ii) failure of the issuer to pay interest or principal; (iii) volatility of fair value; (iv) changes to the ratings of the security; (v) adverse conditions specific to the security or market; (vi) expected defaults; and (vii) length of time and extent that fair value has been less than the cost basis. The accumulation of this data is used to conclude if a credit loss exists for the specific security, and then to determine the classification of the impairment charge as temporary or other-than-temporary.

In the first quarter of 2012, the Company sold one ARS at auction for its full par value and two ARS in a secondary market. The settlement of the three securities resulted in a pre-tax impairment charge of $2.7 million.

Liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the three and nine months ended September 30, 2012 and 2011 are as follows (in thousands):

	Contingent Consideration

Fair value measured prior to conclusion of purchase price analysis measurement period		5,500
Balance at June 30, 2011	$	9,700
Fair value adjustments included in other income (expense), net		(1,432	)
Fair value measured prior to conclusion of purchase price analysis measurement period		40,432
Balance at September 30, 2011	$	48,700

The fair values of the contingent consideration were estimated utilizing an income approach which is based on the cash flows that the acquired entity is expected to generate in the future. This approach requires management to project revenues, operating expenses, working capital investment, capital spending and cash flows for the reporting unit over a multi-year period, as well as determine the weighted average cost of capital to be used as a discount rate (weighted average cost of capital inputs have ranged from 14%-18%).

The carrying amount of cash and cash equivalents approximates fair value due to the short-term nature of these items. The carrying values of receivables, payables, other amounts arising out of normal contract activities, including retainage, which may be settled beyond one year, are estimated to approximate fair value. Of the Company's long-term debt, the fair value of the fixed rate senior unsecured notes as of September 30, 2012 was $303.8 million, compared to its carrying value of $298.2 million. The fair value of the senior unsecured notes was estimated based on market quotations at September 30, 2012. The carrying value of the remaining balance of the Company's long-term debt of $402.6 million at September 30, 2012 is estimated to approximate fair value.

There were no significant transfers between Level 1 and Level 2 financial assets and liabilities that are fair valued on a recurring basis during the nine months ended September 30, 2012 and 2011.

Contingencies and Commitments [Abstract]

Contingencies and Commitments

(7) Contingencies and Commitments

The Company and certain of its subsidiaries are involved in litigation and are contingently liable for commitments and performance guarantees arising in the ordinary course of business. The Company and certain of its clients have made claims arising from the performance under their contracts. The Company recognizes certain significant claims for recovery of incurred cost when it is probable that the claim will result in additional contract revenue and when the amount of the claim can be reliably estimated. These assessments require judgments concerning matters such as litigation developments and outcomes, the anticipated outcome of negotiations, the number of future claims and the cost of both pending and future claims. In addition, because most contingencies are resolved over long periods of time, liabilities may change in the future due to various factors.

Several matters are in the litigation and dispute resolution process. The following discussion provides a background and current status of these matters.

Tutor-Saliba-Perini Joint Venture vs. Los Angeles MTA Matter

During 1995 Tutor-Saliba-Perini ("Joint Venture") filed a complaint in the Superior Court of the State of California for the County of Los Angeles against the Los Angeles County Metropolitan Transportation Authority ("LAMTA"), seeking to recover costs for extra work required by LAMTA in connection with the construction of certain tunnel and station projects. In 1999, LAMTA countered with civil claims under the California False Claims Act against the Joint Venture, Tutor-Saliba and the Company jointly and severally (together, "TSP").

Between 2005 and 2010, the court granted certain Joint Venture motions and LAMTA capitulated on others which reduced the number of false claims LAMTA may seek and limited LAMTA's claims for damages and penalties. In September 2010, LAMTA dismissed its remaining claims and agreed to pay the entire amount of the Joint Venture's remaining claims plus interest. The Court subsequently entered judgment in favor of TSP and against LAMTA in the amount of $3 million. This amount is after deducting the amount of $0.5 million, representing the tunnel handrail verdict plus accrued interest against TSP. The parties filed post-trial motions for costs and fees. The Court ruled TSP's sureties could recover costs, LAMTA could recover costs for the tunnel handrail trial, and no party could recover attorneys' fees. TSP is appealing the false claims jury verdict on the tunnel handrail claim and other issues, including the denial of TSP's and its Sureties' request for attorneys' fees. LAMTA subsequently filed its notice of cross-appeal. In March 2012, the Court finalized the preparation of the record for the Court of Appeal; opening briefs were filed in August 2012. The appeal of this case is expected to take at least a year.

The Company does not expect this matter to have any material effect on its consolidated financial statements.

Perini/Kiewit/Cashman Joint Venture-Central Artery/Tunnel Project Matter

Perini/Kiewit/Cashman Joint Venture ("PKC"), a joint venture in which the Company holds a 56% interest and is the managing partner, is currently pursuing a series of claims, instituted at different times over the course of the past ten years, for additional contract time and/or compensation against the Massachusetts Highway Department ("MHD") for work performed by PKC on a portion of the Central Artery/Tunnel ("CA/T") project in Boston, Massachusetts. During construction, MHD ordered PKC to perform changes to the work and issued related direct cost changes with an estimated value, excluding time delay and inefficiency costs, in excess of $100 million. In addition, PKC encountered a number of unforeseen conditions during construction that greatly increased PKC's cost of performance. MHD has asserted counterclaims for liquidated damages and backcharges.

Certain of PKC's claims have been presented to a Disputes Review Board ("DRB") which consists of three construction experts chosen by the parties. To date, five DRB panels have issued several awards and interim decisions in favor of PKC's claims, amounting to total awards to PKC in excess of $128 million plus interest, of which $110 million were binding awards.

In December 2010, the Suffolk County Superior Court granted MHD's motion for summary judgment to vacate the Third DRB Panel's awards to PKC for approximately $56.5 million. The Court granted the motion on the grounds that the arbitrators do not have authority to decide whether particular claims are subject to the arbitration provision of the contract. MHD subsequently moved to vacate approximately $13.7 million of the Fourth DRB Panel's total awards to PKC on the same arbitrability basis that the Third DRB's awards were vacated. In October 2011, the Suffolk County Superior Court followed its earlier arbitrability rulings holding that the Fourth DRB exceeded its authority in deciding arbitrability with respect to certain of the Fourth DRB Panel's awards (approximately $8 million of the $13.7 million discussed above). PKC is pursuing an appeal of the Superior Court decisions.

In February 2012, PKC received a $22 million payment for an interest award associated with the Second DRB panel's awards to PKC. No trial date has been set in any of the cases as the parties are currently awaiting a decision on the appeal of the Superior Court arbitrability rulings.

Management has made an estimate of the anticipated recovery on this project and it is included in revenue recorded to date. To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the financial statements at that time.

Long Island Expressway/Cross Island Parkway Matter

The Company reconstructed the Long Island Expressway/Cross Island Parkway Interchange (the "Project") for the New York State Department of Transportation (the "NYSDOT"). The $130 million Project was substantially completed in January 2004 and was accepted by the NYSDOT as finally complete in February 2006. The Company incurred significant added costs in completing its work and suffered extended schedule costs due to numerous design errors, undisclosed utility conflicts, lack of coordination with local agencies and other interferences for which the Company believes that the NYSDOT is responsible.

In March 2011, the Company filed its claim and complaint with the New York State Court of Claims and served to the New York State Attorney General's Office, in the amount of $53.8 million. In May 2011, the NYSDOT filed a motion to dismiss the Company's claim on the grounds that the Company had not provided required documentation for project closeout and filing of a claim. In September 2011, the Company reached agreement on final payment with the Comptroller's Office on behalf of the NYSDOT which resulted in an amount of $0.5 million payable to the Company and formally closed out the project, which allowed the Company's claim to be re-filed. The Company re-filed its claim in the amount of $53.8 million with the NYSDOT in February 2012 and with the Court of Claims in March 2012. In May 2012, the NYSDOT served its answer and counterclaims in the amount of $151 million alleging fraud in the inducement and punitive damages related to disadvantaged business enterprise ("DBE") requirements for the Project. The Company does not expect the counterclaim to have any material effect on its consolidated financial statements.

Management has made an estimate of the total anticipated recovery on this project and it is included in revenue recorded to date. To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the financial statements at that time.

Queensridge Matter

Tutor Perini Building Corp. ("TPBC") (formerly Perini Building Company, Inc.), a wholly owned subsidiary of the Company, was the general contractor for the construction of One Queensridge Place, a condominium project in Las Vegas, Nevada. The developer of the project, Queensridge Towers, LLC / Executive Home Builders, Inc. ("Queensridge"), has failed to pay TPBC for work which PBC and its subcontractors performed on the project.

In October 2012, TPBC and Queensridge reached an agreement to settle their respective claims. The settlement did not have a material effect on the Company's consolidated financial statements.

Gaylord Hotel and Convention Center Matter

In 2005, Gaylord National, LLC ("Gaylord"), as Owner, and Perini Building Company, Inc. / Tompkins Builders, Joint Venture ("PTJV"), as Construction Manager, entered into a contract to construct the Gaylord National Resort and Convention Center (the "Project") in Maryland. The Project is complete and as part of its settlement with Gaylord reached in November 2008, PTJV agreed to pay all subcontractors and defend all claims and lien actions by them relating to the Project. PTJV has closed out most subcontracts. Resolution of the issues with the remaining subcontractors may require mediation, arbitration and/or trial.

PTJV is pursuing an insurance claim for approximately $40 million related to work performed by Banker Steel Company, Inc. ("Banker Steel"), a subcontractor, including $11 million for business interruption costs incurred by Gaylord which have effectively been assigned to PTJV. In November 2009, PTJV filed suit against Factory Mutual Insurance Co. ("FM") in the Maryland federal district court alleging FM breached the insurance contracts and for declaratory judgment with respect to the insurance coverage. In December 2010, PTJV filed suit against ACE American Insurance Company ("ACE") in Maryland federal district court alleging ACE breached the general liability insurance contract, requesting a declaratory judgment with respect to the insurance coverage and for bad faith. FM and ACE each brought separate motions for summary judgment. In October, 2012, FM's motion was denied; ACE's motion was granted.

Management has made an estimate of the total anticipated recovery on this project and it is included in revenue recorded to date. To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the financial statements at that time.

Fontainebleau Matter

Desert Mechanical Inc. ("DMI") and Fisk, wholly owned subsidiaries of the Company, were subcontractors on the Fontainebleau Project in Las Vegas ("Fontainebleau"), a hotel/casino complex with approximately 3,800 rooms. In June 2009, Fontainebleau filed for bankruptcy protection, under Chapter 11 of the U.S. Bankruptcy Code, in the Southern District of Florida. Fontainebleau is headquartered in Miami, Florida.

DMI and Fisk filed liens in Nevada for approximately $44 million, representing unreimbursed costs to date and lost profits, including anticipated profits. Other unaffiliated subcontractors have also filed liens. In June 2009, DMI filed suit against Turnberry West Construction, Inc. ("Turnberry"), the general contractor, in the 8th Judicial District Court, Clark County, Nevada, and in May 2010, the court entered an order in favor of DMI for approximately $45 million. DMI is uncertain as to Turnberry's present financial condition.

In January 2010, the Bankruptcy Court approved the sale of the property to Icahn Nevada Gaming Acquisition, LLC and this transaction closed in February 2010. As a result of a July 2010 ruling relating to certain priming liens, there is now approximately $125 million set aside from this sale, which is available for distribution to satisfy the creditor claims based on seniority. The total estimated sustainable lien amount is approximately $350 million. The project lender filed suit against the mechanic's lien claimants, including DMI and Fisk, alleging that certain mechanic's liens are invalid and that all mechanic's liens are subordinate to the lender's claims against the property. The Nevada Supreme Court ruled in October in an advisory opinion at the request of the Bankruptcy Court that lien priorities would be determined in favor of the mechanic lien holders under Nevada law.

Management has made an estimate of the total anticipated recovery on this project and it is included in revenue recorded to date. To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the financial statements at that time.

MGM CityCenter Matter

Tutor Perini Building Corp. ("TPBC") (formerly Perini Building Company, Inc.), a wholly owned subsidiary of the Company, contracted with MGM MIRAGE Design Group ("MGM") in March 2005 to construct the CityCenter project in Las Vegas, Nevada (the "Project"). The Project, which encompasses nineteen separate contracts, is a 66-acre urban mixed use development consisting of hotels, condominiums, retail space and a casino.

The Company achieved substantial completion of the Project in December 2009, and MGM opened the Project to the public on the same date. In March 2010, the Company filed suit against MGM and certain other property owners in the Clark County District Court alleging several claims including breach of contract, among other items.

In a Current Report on Form 8-K filed by MGM in March 2010, and in subsequent communications issued, MGM has asserted that it believes it owes substantially less than the claimed amount and that it has claims for losses in connection with the construction of the Harmon Hotel and is entitled to unspecified offsets for other work on the Project. According to MGM, the total of the offsets and the Harmon Hotel claims exceed the amount claimed by the Company.

In May 2010, MGM filed a counterclaim and third party complaint against the Company and its subsidiary TPBC. The court granted the Company and MGM's joint motion to consolidate all subcontractor initiated actions into the main CityCenter lawsuit. MGM filed a motion to demolish the Harmon Tower, one of the CityCenter buildings. In July 2012, the Court determined that MGM can demolish the Harmon Tower as a "business decision" but that doing so would not be the result of any actions by TPBC during the construction of the project and that the Court's decision is not "a determination as to whether any design defects exist, any noncompliance with code exists, any nonconformance with plans exists or any construction defects exist."

Evidence had been presented at the hearing that the Harmon Tower could be repaired for approximately $21 million, more than $15 million of which is due to design defects that are MGM's responsibility. In August 2012, as part of MGM's motion to demolish the Harmon Tower, the Court found that MGM's testing methodology of extrapolation cannot be presented to a jury. In mid-September MGM filed a request for additional destructive testing. In October 2012, the Court ruled it would allow additional testing but with certain conditions including but not limited to the Court's withdrawing MGM's right to demolish the Harmon and severing the Harmon defects issue from the rest of the case. There will be two cases and two separate juries.

With respect to alleged losses at the Harmon Hotel, the Company has contractual indemnities from the responsible subcontractor, as well as existing insurance coverage that it expects will be available and sufficient to cover any liability that may be associated with this matter. The Company's insurance carrier initiated legal proceedings seeking declaratory relief that their insurance policies do not provide for defense or coverage for matters pertaining to the Harmon Towers. Those proceedings are stayed pending the outcome of the underlying dispute in Nevada District Court. The Company is not aware of a basis for other claims that would amount to material offsets against what MGM owes to the Company. The Company does not expect this matter to have any material effect on its consolidated financial statements.

As of September 2012, MGM has reached agreements with subcontractors to settle at a discount $301 million of amounts previously billed to MGM. The Company has reduced and will continue to reduce amounts included in revenues, cost of construction operations, accounts receivable and accounts payable for the reduction in subcontractor pass-through billings, which the Company would not expect to have an impact on recorded profit. At September 30, 2012, the Company had approximately $192 million recorded as contract receivables for amounts due and owed to the Company and its subcontractors. In December 2011, a portion of the amounts owed to one of the Company's subsidiaries, Fisk, was paid for approximately $15 million. Included in the Company's receivables are pass-through subcontractor billings for contract work and retention, and other requests for equitable adjustment for additional work in the amount of $48 million. As pass-through subcontractor billings are settled, the Company will reduce its mechanic's lien as appropriate. As of September 30, 2012, the Company's mechanic's lien against the project was $191.3 million.

Management has made an estimate of the total anticipated recovery on this project and it is included in revenue recorded to date. To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the financial statements at that time.

Honeywell Street/Queens Boulevard Bridges Matter

In 1999, the Company was awarded a contract for reconstruction of the Honeywell Street/Queens Boulevard Bridges (the "Project") for the City of New York (the "City"). In June 2003, after substantial completion of the Project, the Company initiated an action to recover $8.75 million in claims against the City on behalf of itself and its subcontractors. In March 2010, the City filed counterclaims for $74.6 million and other relief, alleging fraud in connection with the DBE requirements for the Project. In May 2010, the Company served the City with its response to the City's counterclaims and affirmative defenses. No trial date has been set.

The Company does not expect this matter to have any material effect on its consolidated financial statements.

Westgate Planet Hollywood Matter

Tutor-Saliba Corporation ("TSC"), a wholly owned subsidiary of the Company, contracted to construct a time share development in Las Vegas (the "Project") which was substantially completed in December 2009. The Company's claims against the owner, Westgate Planet Hollywood Las Vegas, LLC ("WPH"), relate to unresolved owner change orders and other claims. The Company filed a lien on the project in the amount of $23.2 million, and filed its complaint with the District Court, Clark County, Nevada. Included in the Company's receivables are pass-throughsubcontractor billings for contract work and retention of approximately $12 million. Several subcontractors have also recorded liens, some of which have been released by bonds and some of which have been released as a result of subsequent payment. Westgate has posted a mechanic's lien release bond for $22.3 million.

WPH filed a cross-complaint alleging non-conforming and defective work for approximately $51 million, primarily related to alleged defects, misallocated costs, and liquidated damages. Some or all of the allegations will be defended by counsel appointed by TSC's insurance carrier. WPH has since revised the amount of their counterclaims to approximately $45 million.

Two subcontractor claims have settled before trial. Trial on the remaining issues began in October 2012, and is currently ongoing.

The Company does not expect this matter to have any material effect on its consolidated financial statements. Management has made an estimate of the total anticipated recovery on this project and it is included in revenue recorded to date. To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the financial statements at that time.

100th Street Bus Depot Matter

The Company constructed the 100th Street Bus Depot for the New York City Transit Authority ("NYCTA") in New York. Prior to receiving notice of final acceptance from the NYCTA, this project experienced a failure of the brick façade on the building due to faulty subcontractor work. The Company has not yet received notice of final acceptance of this project from the NYCTA. The Company contends defective structural installation by the Company's steel subcontractor caused or was a causal factor of the brick façade failure.

The Company has tendered its claim to the NYCTA Owner Controlled Insurance Program ("OCIP") and to Chartis Claims, Inc., its insurance carrier. Coverage was denied in January 2011. The OCIP and general liability carriers have filed a declaratory relief action in the United States District Court, Southern District of New York against the Company seeking court determination that no coverage is afforded under their policies. The Company believes it has legal entitlement to recover costs under the policies and pursuing its claim against the carriers for breach of contract and appropriate associated causes of action. The Company has filed its amended answer and counterclaims in response to the declaratory relief action. The Court had scheduled a bench trial for the declaratory relief causes of action for September 2012. Chartis and Lloyd's filed motions for summary judgment on declaratory relief issues in mid-September. The Court adjourned the September trial date and set motions for summary judgment for late November 2012.

Management has made an estimate of the total anticipated recovery on this project and it is included in revenue recorded to date. To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the financial statements at that time.

Brightwater Matter

In 2006, the Department of Natural Resources and Parks Wastewater Treatment Division of King County ("King County"), as Owner, and Vinci Construction Grands Projects/Parsons RCI/Frontier-Kemper, Joint Venture ("VPFK"), as Contractor, entered into a contract to construct the Brightwater Conveyance System and tunnel sections (the "Project") in Washington State. Frontier-Kemper, a wholly owned subsidiary of the Company, is a 20% minority partner in the joint venture.

In April 2010, King County filed a lawsuit alleging damages in the amount of $74 million, plus costs, for VPFK's failure to complete specified components of the project in the King County Superior Court, State of Washington. Shortly thereafter, VPFK filed a counterclaim in the amount of approximately $75 million, seeking reimbursement for additional costs incurred as a result of differing site conditions, King County's defective specifications, for damages sustained on VPFK's tunnel boring machines ("TBM"), and increased costs as a result of hyperbaric interventions. VPFK's claims related to differing site conditions, defective design specifications, and damages to the TBM were presented to a Dispute Resolution Board ("DRB"). King County amended the amount sought in its lawsuit to approximately $132 million. In August 2011, the DRB generally found that King County was liable to VPFK for VPFK's claims for encountering differing site conditions, including damages to the TBM, but not on VPFK's alternative theory of defective specifications. From June through August 2012, each party filed several motions for summary judgment on certain claims and requests in preparation for trial, which were heard and ruled upon by the Court. The Court granted and denied various requests of each party related to evidence and damages.

Trial started in early September and is currently ongoing.

The ultimate financial impact of King County's lawsuit is not yet determinable. Management has made an estimate of the total anticipated recovery on the submitted claims and it is included in revenue recorded to date. To the extent new facts become known or the final recovery included in the claim settlement varies from the estimate, the impact of the change will be reflected in the financial statements at that time.

156 Stations Matter

In December 2003, Five Star Electric Corporation ("FSE"), a wholly owned subsidiary of the Company, entered into an agreement with the Prime Contractor Transit Technologies, L.L.C ("Transit"), a Consortium member of Siemens Transportation Transit Technologies, L.L.C ("Siemens"), to assist in the installation of new public address and customer information screens system for each of the 156 stations for the New York City Transit Authority ("NYCTA") as the owner. Work on the project commenced in early 2004 and is substantially complete.

In June 2007, FSE submitted a Demand for Arbitration against Transit to terminate FSE's subcontract due to: the execution of a Cure Agreement between the NYCTA, Siemens and Transit, which amended FSE's rights under the Prime Contract; Transit's failure to provide information and equipment to allow work to progress according to the approved schedule, and for failure to tender payment in excess of a year. In June 2012, the arbitration panel awarded FSE a total of approximately $11.9 million to be paid within 45 days, and Transit's claims were denied. FSE filed a motion to confirm arbitration award in District Court in July 2012. In late August 2012, Transit Technologies filed a cross petition to vacate the award. A decision from the Court is expected by the end of 2012. The eventual resolution of this matter is not expected to have a material effect on the Company's consolidated financial statements.

(1) Basis of Presentation

The unaudited consolidated condensed financial statements presented herein include the accounts of Tutor Perini Corporation and its wholly owned subsidiaries ("Tutor Perini" or the "Company"). The Company's interests in construction joint ventures are accounted for using the proportionate consolidation method. These unaudited consolidated condensed financial statements have been prepared in accordance with the instructions to Form 10-Q and do not include all of the information and note disclosures required by accounting principles generally accepted in the United States of America. These statements should be read in conjunction with the financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2011. In the opinion of management, the accompanying unaudited consolidated condensed financial statements include all adjustments, consisting only of normal recurring adjustments, necessary to present fairly the Company's financial position as of September 30, 2012 and December 31, 2011, results of operations and comprehensive income for the three and nine months ended September 30, 2012 and 2011, and cash flows for the nine months ended September 30, 2012 and 2011. The results of operations for the three and nine months ended September 30, 2012 are not indicative of the results that may be expected for the year ending December 31, 2012 because, among other reasons, such results can vary depending on the timing of progress achieved and changes in estimated profitability of projects being reported.

Prior to the quarterly reporting period ended June 30, 2012, the Company had presented payments related to the deferred purchase price obligation of previous acquisitions within cash flows used by investing activities in the Consolidated Condensed Statement of Cash Flows. The Company corrected this presentation to appropriately reflect the cash paid to settle the liability recognized at fair value at the conclusion of the measurement period within cash flows used by financing activities, and the remaining cash paid (e.g., changes in fair value of the liability after the conclusion of the measurement period), was reclassified within cash flows used by operating activities. For the nine months ended September 30, 2012 and 2011 this correction resulted in a decrease in cash flows provided by operating activities of $0 and $1.1 million, an increase in cash flows provided by investing activities of $1.2 million and $3.0 million, and a decrease in cash flows provided by financing activities of $1.2 million and $1.9 million, respectively, in the Consolidated Condensed Statement of Cash Flows. There was no impact on the Company's Consolidated Condensed Statements of Operations or Balance Sheets previously reported.

The Company considers events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosures.

[1] Cash, cash equivalents and restricted cash consist primarily of money market funds with original maturity dates of three months or less, for which fair value is determined through quoted market prices.

[2] Short-term investments are classified as other current assets and are comprised of municipal bonds, the majority of which are rated Aa2 or better. The fair values of the municipal bonds are obtained from readily-available pricing sources for comparable instruments, and as such, the Company has classified these assets as Level 2.

[3] Bonds substituted for retainage are classified as accounts receivable, including retainage and are comprised of U.S. Treasury Notes and other municipal bonds, the majority of which are rated Aa3 or better. The fair values of these assets are obtained from readily-available pricing sources for comparable instruments, and as such, the Company has classified these assets as Level 2.

[4] At September 30, 2012 the Company had $46.3 million invested in auction rate securities ("ARS") which the Company considers as available-for-sale long-term investments. The long-term investments ARS held by the Company at September 30, 2012 are in securities collateralized by student loan portfolios. At September 30, 2012 most of the Company's ARS were rated AAA and AA+. The Company estimated the fair value of its ARS utilizing an income approach valuation model which considered, among other items, the following inputs: (i) the underlying structure of each security; (ii) the present value of future principal and interest payments discounted at rates considered to reflect current market conditions (discount rates range from 3% to 7%); (iii) consideration of the probabilities of default or repurchase at par for each period (term periods range from 6 to 8 years); (iv) prices from recent comparable transactions; and (v) other third party pricing information without adjustment. See the Level 3 ARS rollforward below for disclosure of the Company's valuation approach.

[5] As discussed in Note 10 – Financial Commitments, the Company entered into a swap agreement with Bank of America, N.A. to establish a long-term interest rate for its $200 million five-year term loan. The swap agreement became effective for the term loan principal balance outstanding at January 31, 2012 and will remain effective through the maturity date of the term loan. The Company values the interest rate swap liability utilizing a discounted cash flow model that takes into consideration forward interest rates observable in the market and the counterparty's credit risk. This liability is classified as a component of other long-term liabilities.

[6] The liabilities listed as of September 30, 2012 above represent the contingent consideration for the Company's recent acquisitions for which the measurement period for purchase price analysis has concluded. See the Level 3 contingent consideration rollforward below for disclosure of the Company's valuation approach.

Earnings (Losses) per Common Share

Earnings (Losses) per Common Share [Abstract]

Earnings (Losses) per Common Share

(11) Earnings (Losses) per Common Share

Basic earnings (losses) per common share were computed by dividing net income by the weighted average number of common shares outstanding. Diluted earnings (losses) per common share were similarly computed after giving consideration to the dilutive effect of stock options and restricted stock awards outstanding on the weighted average number of common shares outstanding. The computation of diluted earnings (loss) per common share for the three months ended September 30, 2012 excludes 1,315,465 stock option shares, and for the nine months ended September 30, 2012 excludes 1,315,465 stock option shares and 1,358,332 restricted stock units, respectively, because these shares would have an antidilutive effect. The computation of diluted earnings per common share for the three and nine months ended September 30, 2011 excludes 247,500 restricted stock units and 920,465 stock options.
