ITEM 1. BUSINESS

General

Tutor Perini Corporation, formerly known as Perini Corporation, was incorporated in 1918 as a successor to businesses which had been engaged in providing construction services since 1894. Tutor Perini Corporation and its consolidated subsidiaries (or “Tutor Perini,” “Company,” “we,” “us,” and “our,” unless the context indicates otherwise) is a leading construction company, based on revenues, as ranked by Engineering News-Record, or “ENR”, offering diversified general contracting, construction management and design-build services to private customers and public agencies throughout the world.

We and our predecessors have provided construction services since 1894 and have established a strong reputation within our markets by executing large, complex projects on time and within budget while adhering to strict quality control measures. We offer general contracting, pre-construction planning and comprehensive project management services, including the planning and scheduling of the manpower, equipment, materials and subcontractors required for a project. We also offer self-performed construction services including site work, concrete forming and placement, steel erection, electrical and mechanical, plumbing and HVAC.

During 2012, we performed work on over 1,200 construction projects for over 500 federal, state and local government agencies or authorities and private customers. Our corporate headquarters are in Sylmar, California, and we have various other principal office locations throughout the United States and certain U.S. territories (see Item 2. Properties for a listing of our major facilities). Our common stock is listed on the New York Stock Exchange under the symbol “TPC”. We are incorporated under the laws of the Commonwealth of Massachusetts.

Our business is conducted through four basic segments: Building, Civil, Specialty Contractors and Management Services as described below in the “Business Segment Overview”.

Historically we have been recognized as one of the leading building contractors in the United States as evidenced by our performance on several of the largest hospitality and gaming projects, including Project CityCenter, the Cosmopolitan Casino and Resort and the McCarran International Airport Terminal 3 in Las Vegas, Nevada. In 2008, we embarked upon a strategy to better align our business to pursue markets with higher profitability margins and with the best long-term growth potential, while maintaining our presence as a leading contractor in the general building market. In September 2008, we completed a merger with Tutor-Saliba Corporation (“Tutor-Saliba”) to provide us with enhanced opportunities for growth not available to us on a stand-alone basis through increased size, scale, and management capabilities, complementary assets and expertise, particularly Tutor-Saliba’s expertise in civil projects, immediate access to multiple geographic regions, and increased ability to compete for a large number of projects, particularly in the civil construction segment due to an increased bonding capacity. The success of the Tutor-Saliba merger and the execution of the Company’s strategy to focus on acquiring higher-margin building and civil public work are best illustrated by the dramatic growth we have experienced in our Civil segment. Despite the economic challenges associated with state and local funding over the past four years, our Civil segment’s backlog, revenue and income from construction operations have more than tripled since 2008.

Table of Contents

In late 2010, we saw opportunities to continue to build our Company vertically and geographically through strategic acquisitions of companies which have demonstrated success in their respective markets. By the third quarter of 2011, we had completed the acquisition of seven companies with a combined backlog of $2.6 billion at their respective acquisition dates. To fund the acquisitions, we issued $300 million of senior unsecured notes in October 2010 and a $200 million five-year term loan in August 2011. These acquisitions strengthened our geographic presence in our Building and Civil segments and also significantly increased our specialty contracting capabilities. In the third quarter of 2011, we completed an internal reorganization of our reporting segments with the creation of the Specialty Contractors segment, which we describe below. We believe that the successful completion of our acquisition strategy has enabled us to realize cross-selling opportunities across an expanded geographic footprint, while continuing to focus on vertical integration through increased self-performed work capabilities, thus further improving profitability, and providing greater stability during economic cycles.

Business Segment Overview

Civil Segment

Our Civil segment specializes in public works construction and the repair, replacement and reconstruction of infrastructure across most of the major geographic regions of the United States. Our civil contracting services include construction and rehabilitation of highways, bridges, mass transit systems, and wastewater treatment facilities. Our customers primarily award contracts through one of two methods: the traditional public "competitive bid" method, in which price is the major determining factor, or through a request for proposals where contracts are awarded based on a combination of technical capability and price.

Traditionally, our Civil segment customers require each contractor to pre-qualify for construction business by meeting criteria that include technical capabilities and financial strength. Our financial strength and outstanding record of performance on challenging civil works projects often enables us to pre-qualify for projects in situations where smaller, less diversified contractors are unable to meet the qualification requirements. We believe this is a competitive advantage that makes us an attractive partner on the largest infrastructure projects and prestigious design-build, or DBOM (design-build-operate-maintain) contracts, which combine the nation's top contractors with engineering firms, equipment manufacturers and project development consultants in a competitive bid selection process to execute highly sophisticated public works projects. In its 2012 rankings based on revenue, ENR ranked us as the nation’s second largest contractor in the airports market, third largest in the bridge market, fifth largest domestic contractor in heavy construction, sixth largest in the transportation market, seventh largest in wastewater treatment plants, ninth largest overall general contractor, ninth largest in sewerage and solid waste, and tenth largest in mass transit.

We believe the Civil segment provides significant opportunities for growth due to the age and condition of existing infrastructure coupled with large government funding sources aimed at the replacement and repair of aging U.S. infrastructure, including the increase in alternative funding sources such as public-private partnerships. A two-year $105 billion transportation funding bill was passed in June 2012, which provides funding for a significant number of large highway, bridge, and transit infrastructure projects nationwide. Other multiple dedicated sources of funding for transportation at the local, state and federal levels also exist in the form of dedicated taxes, bond funding, and the Federal Highway Trust Fund.

We have been active in civil construction since 1894 and believe we have a particular expertise in large, complex civil construction projects. We have completed or are currently working on some of the most significant civil construction projects in the United States. For example, we are currently working on the Alaskan Way Viaduct Highway (SR-99) bored tunnel project in Seattle, Washington; the Queens Plaza substation project in Queens, New York; the reconstruction of the I-95 MD43 interchange in Baltimore, Maryland; the rehabilitation of the Tappan Zee Bridge in Westchester County, New York; the I-5 Bridge replacement in Shasta County, California; the Caldecott Tunnel project near Oakland, California; the New Irvington Tunnel in Fremont, California; the Harold Structures mass transit project in Queens, New York; and the construction of express toll lanes along I-95 in Maryland. We have also completed work on the John F. Kennedy International Airport runway widening in Queens, New York; the runway paving at Andrews AFB in Maryland; and various segments of the Greenwich Street corridor project in New York, New York.

Table of Contents

In recent years, we have significantly expanded our Civil segment through a number of acquisitions. In June 2011, we acquired Frontier-Kemper, an Indiana-based privately-held corporation that builds tunnels for highways, railroads, subways, rapid transit systems as well as shafts and other facilities for water supply and wastewater transport. It also develops and equips mines with innovative hoisting, elevator and vertical conveyance systems for the mining industry. In July 2011, we acquired Lunda, a privately-held Wisconsin-based 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. In August 2011, we acquired Becho, a privately-held Utah-based corporation specializing in drilling, foundation, and excavation support for shoring, bridges, piers, roads and highway projects primarily in the southwestern United States. We believe that the Company has benefitted through these acquisitions by allowing us to expand our geographic presence, enhance our civil construction capabilities and add experienced management with a proven, successful track record.

Building Segment

Our Building segment has significant experience providing services to a number of specialized building markets for private and public works customers, including the hospitality and gaming, transportation, healthcare, municipal offices, sports and entertainment, education, correctional facilities, biotech, pharmaceutical, industrial and high-tech markets. We believe our success within the Building segment results from our proven ability to manage and perform large, complex projects with aggressive fast-track schedules, elaborate designs and advanced mechanical, electrical and life safety systems, while providing accurate budgeting and strict quality control. Although price is a key competitive factor, we believe our strong reputation, long-standing customer relationships and significant level of repeat and referral business have enabled us to achieve our leading position.

In its 2012 rankings based on revenue, ENR ranked us as the seventh largest contractor in the United States in the general building market. Within the general building category, we were ranked as the largest builder in the entertainment facilities market, the seventh largest in the sports market, the eighth largest in commercial offices, and the eleventh largest in the education and retail markets. We were also ranked the fifth largest green building contractor in the United States and, within that category, the largest green contractor in the sports, entertainment, and civic markets. We are a recognized leader in the hospitality and gaming market, specializing in the construction of high-end destination resorts and casinos and Native American developments. We work with hotel operators, Native American tribal councils, developers and architectural firms to provide diversified construction services to meet the challenges of new construction and renovation of hotel and resort properties. We believe that our reputation for completing projects on time is a significant competitive advantage in this market, as any delay in project completion could result in significant loss of revenues for the customer.

We have been awarded and have recently completed, or are currently working on, large public works and private building projects across a wide array of building end markets including transportation, healthcare and entertainment, among others, including the Graton Rancheria Resort and Casino in Rohnert Park, California; a new academic building at the State University of New York in Brooklyn; the McCarran International Airport Terminal 3 in Las Vegas, Nevada; the Pennsylvania Convention Center in Philadelphia, Pennsylvania; Kaiser Hospital Buildings in San Leandro and Redwood City and courthouses in San Bernardino, California and Broward County, Florida. As a result of our reputation and track record, we were awarded and have completed contracts for several marquee projects in the hospitality and gaming market, including the Resorts World New York Casino at Aqueduct Racetrack in Jamaica, New York, and Project CityCenter, The Cosmopolitan Resort and Casino, the Wynn Encore Hotel and the Planet Hollywood Tower, all in Las Vegas, Nevada. In 2012, we were retained by Related Companies and Oxford Property Group as general contractor for the Hudson Yards development in New York City and for a residential tower just south of Hudson Yards. Hudson Yards is a 26-acre mixed-use development accommodating over 13 million square feet of commercial and residential space. These projects span a wide array of building end markets, and they illustrate our Building segment’s resume of performance on large-scale public and private projects.

Table of Contents

Over the past several years, we have supported our Building segment’s book of business through strategic acquisitions. In January 2009, we acquired Keating Building Company (“Keating”), a privately-held Philadelphia-based construction, construction management and design-build company with expertise in both private and public works building projects. The acquisition of Keating enabled us to expand our building construction market presence in the eastern half of the United States, including the northeast and mid-Atlantic regions. In April 2011, we acquired Anderson Companies (“Anderson”), the privately held parent company of Roy Anderson Corporation, Harrell Contracting Group, LLC and Brice Building Company, LLC. Anderson provides general contracting, design-build, preconstruction, and construction management services to its public and private customers throughout the southeastern United States and has expertise in hospitality and gaming, commercial, government, health care, industrial and educational facilities. We believe that the Company has benefitted through these acquisitions by strengthening our positions in the eastern United States, and we believe that our national resources and strong resume of notable projects will enable future growth potential for these companies on large, complex building projects going forward.

Specialty Contractors Segment

During the third quarter of 2011, we completed an internal reorganization in which we formed a Specialty Contractors segment by grouping together a number of businesses that formerly had operated as part of our Building and Civil segments. The reorganization allowed us to achieve greater vertical integration through increased self-performed work capability, while maintaining a specialty contracting business with third parties that allows us to sell services as a subcontractor. This reorganization strengthened the Company’s position as a full-service contractor with greater control over scheduled work, project delivery and risk management.

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 Specialty Contractors segment has been awarded, has recently completed work on, or is currently working on, the World Trade Center for the Port Authority of New York and New Jersey in New York, New York, and the new hospital at the University of Texas Southwestern Medical Center, and it has also supported several large public works projects in our Building and Civil segments including the Alaskan Way Viaduct (SR-99) bored tunnel project in Seattle Washington; the McCarran International Airport Terminal 3 in Las Vegas, Nevada; the Resorts World New York Casino at Aqueduct Racetrack in Jamaica, New York; various segments of the Greenwich Street Corridor project in New York, New York; the Caldecott Tunnel Project near Oakland, California; the New Irvington Tunnel in Fremont, California and several marquee projects in the hospitality and gaming market, including Project CityCenter, The Cosmopolitan Resort and Casino, and the Planet Hollywood Tower, all in Las Vegas, Nevada.

Prior to the establishment of the Specialty Contractors segment, we significantly increased our specialty contracting capabilities with several acquisitions in 2010 and 2011. We acquired Superior Gunite (“Superior”) in November 2010, Fisk Electric Company (“Fisk”) in January 2011, and Five Star Electric Corporation (“FSE”), WDF, Inc. (“WDF”), and Nagelbush Mechanical, Inc. (“Nagelbush”) in July 2011, because we determined that they could enhance our opportunities for both increased vertical integration and continued (and expanded) stand-alone specialty contracting activities.

Superior specializes in pneumatically placed structural concrete utilized in infrastructure projects such as bridges, dams, tunnels and retaining walls.

Fisk covers many of the major commercial, transportation and industrial electrical construction markets in southwestern and southeastern United States locations with the ability to cover other attractive markets nationwide. Fisk's expertise is in the design and development of electrical and technology systems for major projects spanning a broad variety of project types, including: commercial office buildings, sports arenas, hospitals, research laboratories, hospitality and casinos, convention centers, and industrial facilities.

FSE, WDF and Nagelbush serve a range of customers in a wide variety of markets including transportation, infrastructure, commercial, schools and universities, residential, and specialty construction, with a large presence in the northeastern United States markets.

Management Services Segment

Our Management Services segment provides diversified construction and design-build services to the U.S. military and government agencies, as well as to surety companies and multi-national corporations in the United States and overseas. Our ability to plan and execute rapid-response assignments and multi-year contracts through our diversified construction and design-build capabilities provides us with a competitive edge. Based on superior past performance, we have been selected for and are currently participating in nine multi-year, multi-trade, task order and ID/IQ (Indefinite Delivery/Indefinite Quantity) construction programs for the U.S. Departments of Defense, State, Interior, and Homeland Security. We have been chosen by the federal government for significant projects related to defense and international development reconstruction projects in Iraq, Afghanistan, Haiti, and Guam. For example, we have completed in excess of two million square feet of overhead coverage protection projects throughout Iraq, a housing complex and a helicopter maintenance facility for the U.S. Government. In addition, we completed work on the design and construction of four military bases in Afghanistan for the Afghan National Army, and we are working on electrical infrastructure improvements in Afghanistan and Haiti.

We believe we are well-positioned to capture additional management services projects that involve long-term contracts and provide a recurring source of revenues as the U.S government continues significant expenditures for defense and homeland security given the sustained global threat of terrorism, as well as for international development programs that improve livelihoods, promote governance and democratic states, and bolster diplomatic relations. Despite the recent U.S. military troop reductions in Iraq and Afghanistan, we anticipate winning a sizeable share of the work remaining under the existing ID/IQ programs in those regions, including various vertical structures, energy, and water projects. We also anticipate supporting future growth in this segment through opportunities in regions such as Guam as the United States military expands its presence on the island, as well as through reconstruction projects in Haiti, North Africa, and other regions of the Middle East. Black Construction, one of our subsidiaries and the largest contractor on the island of Guam, is expected to generate a portion of its future revenues from the construction of facilities during the planned expansion of the United States military’s presence in Guam. Our proven capabilities with federal government projects have also enabled us to win contracts from private defense contractors who are executing projects for the federal government.

We also provide diversified management services to surety companies and multi-national corporations. We are under agreement with a major North American surety company to provide rapid response, contract completion services. Upon notification from the surety of a contractor bond default, we provide management or general contracting services to fulfill the contractual and financial obligations of the surety.

Markets and Customers

Our construction services are targeted toward end markets that are diversified across project types, customer characteristics and geographic locations. In conjunction with our 2011 reorganization, we have restated comparative prior period information for the reorganized reportable segments in each of the revenue and backlog tabular disclosures below. We have also restated comparative prior period results to allocate intersegment eliminations of revenues into the applicable Building, Civil or Management Services segments to which the Specialty Contractors segment has provided services.

We provide our services to a broad range of private and public customers. The allocation of our revenues by customer source for fiscal years 2012, 2011 and 2010 is set forth below:

	Revenues by Customer Source

Federal Government Agencies		6	%		10	%		9	%
		100	%		100	%		100	%

State and Local Governments. We derived approximately 53% of our revenues from state and local government customers during 2012. Our state and local government customers include state transportation departments, metropolitan authorities, cities, municipal agencies, school districts and public universities. We provide services to our state and local customers primarily pursuant to contracts awarded through competitive bidding processes. Our building construction services for state and local government customers have included correctional facilities, schools and dormitories, healthcare facilities, convention centers, parking structures and municipal buildings. Our civil contracting and building construction services are in locations throughout the country.

Private Owners. We derived approximately 41% of our revenues from private customers during 2012. Our private customers include major hospitality and gaming resort owners, Native American sovereign nations, public corporations, private developers, healthcare companies and private universities. We provide services to our private customers through negotiated contract arrangements as well as through competitive bids.

Table of Contents

Federal Government Agencies. We derived approximately 6% of our revenues from federal government agencies during 2012. These agencies have included the U.S. State Department, the U.S. Navy, the U.S. Army Corps of Engineers, and the U.S. Air Force. We provide services to federal agencies primarily pursuant to contracts for specific or multi-year assignments that involve new construction or infrastructure improvements. A substantial portion of our revenues from federal agencies is derived from projects in overseas locations. We expect this to continue for the foreseeable future as a result of our expanding base of experience and relationships with federal agencies, together with an anticipated favorable expenditure trend for defense, security and reconstruction work primarily due to the ongoing threats of terrorism.

Most federal, state, and local government contracts contain provisions which permit the termination of contracts, in whole or in part, for the convenience of the government, among other reasons.

For additional information on customers, markets, measures of profit or loss, and total assets, both U.S and foreign, see Note 13 – Business Segments of Notes to Consolidated Financial Statements in Item 15. Exhibits and Financial Statement Schedules.

Backlog

We include a construction project in our backlog at such time as a contract is awarded or a letter of commitment is obtained and adequate construction funding is in place. As a result, we believe the backlog figures are firm, subject only to the cancellation provisions contained in the various contracts. Historically, these provisions have not had a material effect on us.

Backlog is summarized below by business segment as of December 31, 2012 and 2011:

We have seen a significant shift in the mix of our customers from private to state and local government agencies along with an increased share of Civil segment’s contributions to revenues and operating profits over the past three years. We intend to focus on increasing our share of higher margin public works projects and vertically integrating our specialty contracting capabilities to further enhance our consolidated operating margins, as well as continuing to capture our share of large private building work on an opportunistic basis.

Competition

The construction industry is highly competitive and the markets in which we compete include numerous competitors. In the small to mid-size work that we have targeted, we have experienced an increase in pricing competition from our competitors. However, the majority of the work that we target is for larger, more complex projects where the number of active market participants is smaller because of the capabilities required to perform the work. As a result, we face fewer competitors, as smaller contractors are unable to effectively compete or are unable to secure bonding to support large projects.

In certain end markets of the Building segment, such as hospitality and gaming and healthcare, we are one of the largest providers of construction services in the United States. In our Building segment, we compete with a variety of national and regional contractors. Our primary competitors are Balfour Beatty Construction, Clark Construction Group, DPR Construction, Gilbane, Inc., Hensel Phelps Construction Co., Hunt Construction Group, McCarthy Building Companies, Inc., Skanska USA, Tishman Construction, Turner Construction Co., The Walsh Group and The Whiting-Turner Contracting Co. In our Civil segment, we compete principally with large civil construction firms including Alberici Corp., American Infrastructure, Inc., Dragados USA, Flatiron Construction Corp., Fluor Corp., Granite Construction, Kiewit Corp., Skanska USA, SNC-Lavalin Group, Inc., Sterling Construction Co., Traylor Bros., Inc., and The Walsh Group. In our Specialty Contractors segment, we compete principally with Bergelectric Corp., Comfort Systems USA, E-J Electric Installation Co., EMCOR Group, KSW Mechanical Services, Inc., MC Dean, Inc., Primoris Services Corp., Rosendin Electric, Inc., and Zwicker Electric Co., Inc. In our Management Services segment, we compete principally with national engineering and construction firms such as CH2M Hill, Inc., Fluor Corp., Hensel Phelps Construction Co., KBR, Shaw Group, and the Washington Division of URS Corp. We believe price, experience, reputation, responsiveness, customer relationships, project completion track record, schedule control and delivery, risk management and quality of work are key factors in customers awarding contracts across our end markets.

Types of Contracts and The Contract Process

Types of Contracts

The general contracting and management services we provide consist of planning and scheduling the manpower, equipment, materials and subcontractors required for the timely completion of a project in accordance with the terms, plans and specifications contained in a construction contract. We provide these services by entering into traditional general contracting arrangements, such as guaranteed maximum price, cost plus fee and fixed price contracts as well as construction management or design-build contracting arrangements. These contract types and the risks generally inherent therein are discussed below:

Fixed price (FP) contracts, which include fixed unit price contracts, are generally used in competitively bid public civil, building, and specialty construction projects and generally commit the contractor to provide all of the resources required to complete a project for a fixed sum or at fixed unit prices. Usually FP contracts transfer more risk to the contractor but offer the opportunity, under favorable circumstances, for greater profits. FP contracts represent a significant portion of our publicly bid civil construction projects. We also perform publicly bid building and specialty construction projects and certain task order contracts for agencies of the U.S. government in our Management Services segment under FP contracts.

Table of Contents

Guaranteed maximum price (GMP) contracts provide for a cost plus fee arrangement up to a maximum agreed upon price. These contracts place risks on the contractor for amounts in excess of the GMP, but may permit an opportunity for greater profits than under Cost Plus contracts through sharing agreements with the owner on any cost savings that may be realized. Services provided by our Building segment to various private customers often are performed under GMP contracts.

Cost plus fee (Cost Plus) contracts provide for reimbursement of the costs required to complete a project plus a stipulated fee arrangement. Cost Plus contracts include cost plus fixed fee (CPFF) contracts and cost plus award fee (CPAF) contracts. CPFF contracts provide for reimbursement of the costs required to complete a project plus a fixed fee. CPAF contracts provide for reimbursement of the costs required to complete a project plus a base fee as well as an incentive fee based on cost and/or schedule performance. Cost Plus contracts serve to minimize the contractor’s financial risk, but may also limit profits.

Construction management (CM) contracts are those under which a contractor agrees to manage a project for the owner for an agreed-upon fee, which may be fixed or may vary based upon negotiated factors. CM contracts serve to minimize the contractor’s financial risk, but may also limit profit relative to the overall scope of a project.

Design-build contracts are those under which a contractor provides both design and construction services for a customer. These contracts may be GMP, FP or Cost Plus contracts.

Historically, a high percentage of our contracts have been of the GMP and FP type. As a result of increasing opportunities in public works civil and building markets, combined with our increased resume of notable projects and expertise and the execution of our acquisition strategy in 2010 and 2011, FP contracts have accounted for an increasing portion of our revenues since 2008 and are expected to continue to represent a sizeable percentage of both total revenues and backlog. The composition of revenues and backlog by type of contract for fiscal years 2012, 2011 and 2010 is as follows:

	Revenues for the
	Year Ended December 31,
	2012			2011			2010

The Contract Process

We identify potential projects from a variety of sources, including from advertisements by federal, state and local government agencies, through the efforts of our business development personnel and through meetings with other participants in the construction industry such as architects and engineers. After determining which projects are available, we make a decision on which projects to pursue based on factors such as project size, duration, availability of personnel, current backlog, competitive advantages and disadvantages, prior experience, contracting agency or owner, source of project funding, geographic location and type of contract.

After deciding which contracts to pursue, we generally have to complete a prequalification process with the applicable agency or customer. The prequalification process generally limits bidders to those companies that the agencies or customer concludes have the operational experience and financial capability to effectively complete the particular project(s) in accordance with the plans, specifications and construction schedule.

Our estimating process typically involves three phases. Initially, we perform a detailed review of the plans and specifications, summarize the various types of work involved and related estimated quantities, determine the project duration or schedule and highlight the unique aspects of and risks associated with the project. After the initial review, we decide whether to continue to pursue the project. If we elect to pursue the project, we perform the second phase of the estimating process which consists of estimating the cost and availability of labor, material, equipment, subcontractors and the project team required to complete the project on time and in accordance with the plans and specifications. The final phase consists of a detailed review of the estimate by management including, among other things, assumptions regarding cost, approach, means and methods, productivity and risk. After the final review of the cost estimate, management adds an amount for profit to arrive at the total bid amount.

Public bids to various government agencies are generally awarded to the lowest bidder. Requests for proposals or negotiated contracts with public or private customers are generally awarded based on a combination of technical capability and price, taking into consideration factors such as project schedule and prior experience.

During the construction phase of a project, we monitor our progress by comparing actual costs incurred and quantities completed to date with budgeted amounts and the project schedule and periodically, at a minimum on a quarterly basis, prepare an updated estimate of total forecasted revenue, cost and profit for the project.

During the ordinary course of most projects, the customer, and sometimes the contractor, initiate modifications or changes to the original contract to reflect, among other things, changes in specifications or design, construction method or manner of performance, facilities, equipment, materials, site conditions and period for completion of the work. Generally, the scope and price of these modifications are documented in a "change order" to the original contract and are reviewed, approved and paid in accordance with the normal change order provisions of the contract.

Often a contract requires us to perform extra, or change order, work as directed by the customer even if the customer has not agreed in advance on the scope or price of the work to be performed. This process may result in disputes over whether the work performed is beyond the scope of the work included in the original project plans and specifications or, if the customer agrees that the work performed qualifies as extra work, the price the customer is willing to pay for the extra work. Even when the customer agrees to pay for the extra work, we may be required to fund the cost of such work for a lengthy period of time until the change order is approved and funded by the customer. Also, unapproved change orders, contract disputes or claims result in costs being incurred by us that cannot be billed currently and, therefore, are reflected as "costs and estimated earnings in excess of billings" in our Consolidated Balance Sheets. See Note 1 – Description of Business and Summary of Significant Accounting Policies, under the section entitled Method of Accounting for Contracts, of Notes to Consolidated Financial Statements in Item 15. Exhibits and Financial Statement Schedules. In addition, any delay caused by the extra work may adversely impact the timely scheduling of other project work and our ability to meet specified contract milestone dates.

The process for resolving claims varies from one contract to another, but, in general, we attempt to resolve claims at the project supervisory level through the normal change order process or with higher levels of management within our organization and the customer’s organization. Depending upon the terms of the contract, claim resolution may involve a variety of other resolution methods, including mediation, binding or non-binding arbitration or litigation. Regardless of the process, when a potential claim arises on a project, we typically have the contractual obligation to perform the work and incur the related costs. We do not recoup the costs until the claim is resolved. It is not uncommon for the claim resolution process to last months or years, especially if it involves litigation.

There are a number of factors that can create variability in contract performance and results as compared to a project’s original bid. These include costs associated with added scope changes, extended overhead due to owner, weather, and other delays, subcontractor performance issues, changes in site conditions that differ from those assumed in the original bid, the availability and skill level of workers in the geographic location of the project, and a change in the availability and proximity of equipment or materials. In addition, certain efficiencies and cost savings may at times be realized during the course of a project compared to the originally anticipated costs and levels of productivity. Furthermore, our original bids for most contracts are based on the client’s estimates of quantities needed to complete the contract. All of these factors can cause changes in estimates to a project’s at-completion costs, resulting in favorable or unfavorable impacts to profitability in current and future periods. Because of the rigor of our estimating process, we have often encountered opportunities to improve project performance cost estimates through realized project execution efficiencies and cost savings.

Our civil, building and management services contracts generally involve work durations in excess of one year. Revenue from our contracts in process is generally recorded under the percentage of completion contract accounting method. For a more detailed discussion of our policy in these areas, see Note 1 – Description of Business and Summary of Significant Accounting Policies, under the section entitled Method of Accounting for Contracts, of Notes to Consolidated Financial Statements in Item 15. Exhibits and Financial Statement Schedules.

Construction Costs

While our business may experience some adverse consequences if shortages develop or if prices for materials, labor or equipment increase excessively, provisions in certain types of contracts often shift all or a major portion of any adverse impact to the customer. On our fixed price contracts, we attempt to insulate ourselves from the unfavorable effects of inflation by incorporating escalating wage and price assumptions, where appropriate, into our construction cost estimates and by obtaining firm fixed price quotes from major subcontractors and material suppliers at the time of the bid period. Construction and other materials used in our construction activities are generally available locally from multiple sources and have been in adequate supply during recent years. Construction work in selected overseas areas primarily employs expatriate and local labor which can usually be obtained as required.

Environmental Matters

Our properties and operations are subject to federal, state and municipal laws and regulations relating to the protection of the environment, including requirements for water discharges, air emissions, the use, management and disposal of solid or hazardous materials or wastes and the cleanup of contamination. For example, we must apply water or chemicals to reduce dust on road construction projects and to contain contaminants in storm run-off water at construction sites. In certain circumstances, we may also be required to hire subcontractors to dispose of hazardous materials encountered on a project in accordance with a plan approved in advance by the owner. We believe that we are in substantial compliance with all applicable laws and regulations and we continually evaluate whether we must take additional steps to ensure compliance with environmental laws; however, future requirements or amendments to current laws or regulations imposing more stringent requirements could require us to incur additional costs to maintain or achieve compliance.

In addition, some environmental laws, such as the U.S. federal "Superfund" law and similar state statutes, can impose liability for the entire cost of cleanup of contaminated sites upon any of the current or former owners or operators or upon parties who sent wastes to these sites, regardless of who owned the site at the time of the release or the lawfulness of the original disposal activity. Contaminants have been detected at some of the sites that we own, or where we worked as a contractor in the past, and we have incurred costs for investigation or remediation of hazardous substances. We believe that our liability for these sites will not be material, either individually or in the aggregate, and have pollution liability insurance available for such matters. We believe that we have minimal exposure to environmental liability because we generally carry insurance or receive indemnification from customers to cover the risks associated with the remediation business.

We own real estate in several states and in Guam (see Item 2. Properties for a description of our major properties) and, as an owner, are subject to laws governing environmental responsibility and liability based on ownership. We are not aware of any significant environmental liability associated with our ownership of real estate.

Table of Contents

Insurance and Bonding

All of our properties and equipment, both directly owned and owned through joint ventures with others, are covered by insurance and we believe that the amount and scope of such insurance is adequate for the risks we face. In addition, we maintain general liability, excess liability and workers’ compensation insurance in amounts that we believe are consistent with our risk of loss and industry practice.

As a normal part of the construction business, we are often required to provide various types of surety bonds as an additional level of security of our performance. We have surety arrangements with several sureties. We also require many of our higher risk subcontractors to provide surety bonds as security for their performance. Historically, we also have purchased contract default insurance on certain construction projects to insure against the risk of subcontractor default as opposed to having subcontractors provide traditional payment and performance bonds. In 2008, we formed PCR Insurance Company, a wholly-owned subsidiary, to consolidate the risk under our various insurance policies utilizing deductible reimbursement policies issued by PCR Insurance Company, for each of our subsidiaries’ contractor default insurance, auto liability, general liability and workers’ compensation insurance exposure. PCR Insurance Company provides high deductible insurance coverage and reinsurance to other business units. The formation of PCR Insurance Company has allowed us to take advantage of favorable tax opportunities, and to centralize our claims and risk management functions, thus reducing claims and insurance-related costs.

Employees

The total number of personnel employed by us is subject to seasonal fluctuations, the volume of construction in progress and the relative amount of work performed by subcontractors. Our average number of full time equivalent employees during 2012 was 10,085, and our total number of employees at December 31, 2012 was 11,016. The increase in the average from 5,796 in 2011 to 10,085 in 2012 is primarily a reflection of the increased personnel obtained through the completion of our acquisition strategy in 2011.

We are signatory to numerous local and regional collective bargaining agreements, both directly and through trade associations, as a union contractor. These agreements cover all necessary union crafts and are subject to various renewal dates. Estimated amounts for wage escalation related to the expiration of union contracts are included in our bids on various projects and, as a result, the expiration of any union contract in the next fiscal year is not expected to have any material impact on us. As of December 31, 2012, approximately 8,099 of our total of 11,016 employees were union employees. During the past several years, we have not experienced any significant work stoppages caused by our union employees.

ITEM 1A. RISK FACTORS

We are subject to a number of risks, including those summarized below. Such risks could have a material effect on our financial condition, results of operations and cash flows.

We may not fully realize the revenue value reported in our backlog.

As of December 31, 2012, our backlog of uncompleted construction work was approximately $5.6 billion. We include a construction project in our backlog at such time as a contract is awarded or a letter of commitment is obtained and adequate construction funding is in place. The revenue projected in our backlog may not be realized or, if realized, may not result in profits. For example, if a project reflected in our backlog is terminated, suspended or reduced in scope, it would result in a reduction to our backlog which could reduce, potentially to a material extent, the revenues and profits realized. If a customer cancels a project, we may be reimbursed for certain costs and profit thereon but typically have no contractual right to the total revenues reflected in our backlog. Significant cancellations or delays of projects in our backlog could have a material effect on future revenues, profits, and cash flows.

Current economic conditions could adversely affect our operations.

The deterioration of economic and financial market conditions in the United States and overseas throughout 2009-2012, including severe disruptions in the credit markets, could continue to adversely affect our results of operations in future periods. The continued instability in the financial markets has made it difficult for certain of our customers, including private owners and state and local governments, to access the credit markets to obtain financing or refinancing, as the case may be, to fund new construction projects on satisfactory terms or at all. State and local governments continue to face potentially significant budget shortfalls as a result of declining tax and other revenues, which may cause them to defer or cancel planned infrastructure projects. During 2012, we encountered increased levels of deferrals and delays related to new construction projects. Difficulty in obtaining adequate financing due to the unprecedented disruption in the credit markets may significantly increase the rate at which our customers defer, delay or cancel proposed new construction projects. Such deferrals, delays or cancellations could have an adverse impact on our future operating results.

Instability in the financial markets may also impact a customer’s ability to pay us on a timely basis, or at all, for work on projects already under construction in accordance with the contract terms. Customer financing may be subject to periodic renewals and extensions of credit by the lender. As credit markets remain tight and difficult economic conditions persist, lenders may be unwilling to continue renewing or extending credit to a customer. Such deferral, delay or cancellation of credit by the lender could impact the customer’s ability to pay us, which could have an adverse impact on our future operating results. A significant portion of our operations are concentrated in California and New York. As a result, we are more susceptible to fluctuations caused by adverse economic or other conditions in these regions as opposed to others.

Reductions in the level of consumer spending within the non-residential building industry and the level of federal, state and local government spending for infrastructure and other public projects could adversely affect the number of projects available to us in the future.

With regard to the non-residential building industry, consumer spending is discretionary and may decline during economic downturns when consumers have less disposable income. Even an uncertain economic outlook may adversely affect consumer and private industry spending in various business operations, as consumers may spend less in anticipation of a potential economic downturn. Decreased spending in the non-residential building markets could deter new projects within the industry and the expansion or renovation of existing facilities.

With regard to infrastructure and other public works spending, civil construction markets are dependent on the amount of infrastructure work funded by various government agencies which, in turn, depends on the condition of the existing infrastructure, the need for new or expanded infrastructure and federal, state or local government spending levels. A slowdown in economic activity in any of the markets that we serve may result in less spending on public works projects. In addition, a decrease or delay in government funding of infrastructure projects or delays in the implementation of voter-approved bond measures could decrease the number of civil construction projects available and limit our ability to obtain new contracts, which could reduce revenues within our Civil segment. In addition, budget shortfalls and credit rating downgrades in California and other states in which the Company is involved in significant infrastructure projects and any long-term impairment in the ability of state and local governments to finance construction projects by raising capital in the municipal bond market could curtail or delay the funding of future projects. Our Building segment is also involved in significant public works construction projects including healthcare facilities, educational facilities, and municipal and government facilities primarily in California and the southeastern United States. These projects also are dependent upon funding by various federal, state and local government agencies. A decrease in government funding of public healthcare and education facilities, particularly in those regions, could decrease the number and/or size of construction projects available and limit our ability to obtain new contracts in these markets, which could further reduce our revenues and earnings.

Table of Contents

Economic, political and other risks and the level of U.S. government funding associated with our international operations could adversely affect our revenues and earnings.

We derived approximately 5% or $185.7 million of revenues and approximately $18.7 million of income from construction operations for the year ended December 31, 2012 from our work on projects located outside of the United States, including projects in Iraq, Afghanistan and Guam. Our international operations expose us to risks inherent in doing business in certain hostile regions outside the United States, including: political risks, risks of loss due to civil disturbances, guerilla activities and insurrection; acts of terrorism and acts of war; unstable economic, financial and market conditions; potential incompatibility with foreign subcontractors and vendors; foreign currency controls and fluctuations; trade restrictions; variations in taxes; and changes in labor conditions, labor strikes and difficulties in staffing and managing international operations. Failure to successfully manage risks associated with our international operations could result in higher operating costs than anticipated or could delay or limit our ability to generate revenues and income from construction operations in key international markets.

With regard to the U.S. Government’s funding of construction projects in Iraq, Afghanistan and Guam, the United States federal government has approved various spending bills for the reconstruction and defense of Iraq and Afghanistan and has allocated significant funds to the defense of United States interests around the world from the threat of terrorism. The United States federal government has also approved funds for development in conjunction with the relocation of military personnel into Guam. A decrease in government funding of these projects or a decision by the United States federal government to accelerate the withdrawal of troops and support personnel from Afghanistan or reduce or eliminate the use of outside contractors to perform such work would decrease the number of projects available to us and limit our ability to obtain new contracts in this area.

Competition for new project awards is intense and our failure to compete effectively could reduce our market share and profits.

New project awards are often determined through either a competitive bid basis or on a negotiated basis. Bid or negotiated contracts with public or private owners are generally awarded based upon price, but many times take into account other factors, such as shorter project schedules or prior experience with the customer. Within our industry, we compete with many national, regional and local construction firms. Some of these competitors have achieved greater market penetration than we have in the markets in which we compete, and some have greater financial and other resources than we do. As a result, we may need to accept lower contract margins or more fixed price or unit price contracts in order for us to compete against competitors that have the ability to accept awards at lower prices or have a pre-existing relationship with the customer. If we are unable to compete successfully in such markets, our relative market share and profits could be reduced.

The construction services industry is highly schedule driven, and our failure to meet schedule requirements of our contracts could adversely affect our reputation and/or expose us to financial liability.

Many of our contracts are subject to specific completion schedule requirements and subject us to liquidated damages in the event the construction schedules are not achieved. Our failure to meet schedule requirements could subject us not only to liquidated damages, but could further subject us to liability for our customer’s actual cost arising out of our delay and cause us to suffer damage to our reputation within our industry and customer base.

We will require substantial personnel, including construction and project managers and specialty subcontractor resources to execute and perform on our contracts in backlog. The successful execution of our business strategies is also dependent upon our ability to attract and retain key officers.

Our ability to execute and perform on our contracts in backlog depends in large part upon our ability to hire and retain highly skilled personnel, including project and construction management. In addition, our construction projects require a significant amount of trade labor resources, such as carpenters, masons and other skilled workers, as well as certain specialty subcontractor skills. In the event we are unable to attract, hire and retain the requisite personnel and subcontractors necessary to execute and perform on our contract backlog, we may experience delays in completing projects in accordance with project schedules, which may have a material effect on our financial results and harm our reputation. Further, the increased demand for personnel and specialty subcontractors may result in higher costs which could cause us to exceed the budget on a project, which in turn may have a material effect on our results of operations and harm our relationships with our customers. In addition, if we lack the personnel and specialty subcontractors necessary to perform on our current contract backlog, we may find it necessary to curtail our pursuit of new projects. Although the risk has been mitigated with the specialty contracting capabilities that we acquired during 2011, we will still rely on significant external specialty subcontractors to perform our projects.

The execution of our business strategies also substantially depends on our ability to retain the continued service of several key members of our management. Losing the services of these key officers could adversely affect our business until a suitable replacement can be found. The majority of these key officers are not bound by employment agreements with us nor do we maintain key person life insurance policies for them.

An inability to obtain bonding could limit the number of projects we are able to pursue.

As is customary in the construction business, we often are required to provide surety bonds to secure our performance under construction contracts. Our ability to obtain surety bonds primarily depends upon our capitalization, working capital, past performance, management expertise and certain external factors, including the overall capacity of the surety market. Surety companies consider such factors in relation to the amount of our backlog and their underwriting standards, which may change from time to time. The surety industry has undergone significant changes with several companies withdrawing completely from the industry or significantly reducing their bonding commitment. In addition, certain reinsurers of surety risk have limited their participation in this market. Therefore, we could be unable to obtain surety bonds, when required, which could adversely affect our future results of operations and revenues.

Failure to maintain safe work sites could result in significant losses.

Construction and maintenance sites are potentially dangerous workplaces and often put our employees and others in close proximity with mechanized equipment, moving vehicles, chemical and manufacturing processes, and highly regulated materials. On many sites, we are responsible for safety and, accordingly, must implement safety procedures. If we fail to implement these procedures or if the procedures we implement are ineffective, we may suffer the loss of, or injury to our employees, as well as expose ourselves to possible litigation. Despite having invested significant resources in safety programs, a serious accident may nonetheless occur on one of our worksites. As a result, our failure to maintain adequate safety standards could result in reduced profitability or the loss of projects or customers, and could have a material adverse impact on our financial position, results of operations, cash flows and liquidity.

Our participation in construction joint ventures exposes us to liability and/or harm to our reputation for failures by our partners.

As part of our business, we enter into joint venture arrangements typically to jointly bid on and execute particular projects, thereby reducing our financial or operational risk with respect to such projects. Success on these joint projects depends in large part on whether our joint venture partners satisfy their contractual obligations. We and our joint venture partners are generally jointly and severally liable for all liabilities and obligations of our joint ventures. If a joint venture partner fails to perform or is financially unable to bear its portion of required capital contributions or other obligations, including liabilities stemming from lawsuits, we could be required to make additional investments, provide additional services or pay more than our proportionate share of a liability to make up for our partner’s shortfall. Further, if we are unable to adequately address our partner’s performance issues, the customer may terminate the project, which could result in legal liability to us, harm our reputation, and reduce our profit on a projector, in some cases, result in a loss.

Table of Contents

We are subject to significant legal proceedings which, if determined adversely to us, could harm our reputation, preclude us from bidding on future projects and/or have a material effect on us. We also may invest significant working capital on projects while legal proceedings are being settled.

We are involved in various lawsuits, including the legal proceedings described under Item 3. Legal Proceedings. Litigation is inherently uncertain and it is not possible to accurately predict what the final outcome will be of any legal proceeding. We must make certain assumptions and rely on estimates regarding potential outcomes of legal proceedings in order to determine an appropriate charge to income and contingent liabilities. Estimating and recording future outcomes of litigation proceedings requires us to make significant judgments and assumptions about the future, which are inherently subject to risks and uncertainties. If the final recovery turns out to be materially less favorable than our estimates, we would have to record the related liability, which may include losses from money owed pursuant to a disfavorable judgment as well as losses based on the failure to receive an anticipated judgment for sums in our favor, and fund the payment of the judgment and, if such adverse judgment is significant, it could have a material adverse effect on us. Legal proceedings resulting in judgments or findings against us may harm our reputation and prospects for future contract awards. We occasionally bring claims against project owners for additional cost exceeding the contract price or for amounts not included in the original contract price. When these types of events occur and unresolved claims are pending, we may invest significant working capital in projects to cover cost overruns pending the resolution of the relevant claims. A failure to promptly recover on these types of claims could have a material effect on our liquidity and financial results.

Our contracts require us to perform extra or change order work, which can result in disputes and adversely affect our working capital, profits and cash flows.

Our contracts generally require us to perform extra, or change order, work as directed by the customer even if the customer has not agreed in advance on the scope or price of the work to be performed. This process can result in disputes over whether the work performed is beyond the scope of the work included in the original project plans and specifications or, if the customer agrees that the work performed qualifies as extra work, over the price the customer is willing to pay for the extra work. Even when the customer agrees to pay for the extra work, we may be required to fund the cost of such work for a lengthy period of time until the change order is approved and funded by the customer.

Also, unapproved change orders, contract disputes or claims cause us to incur costs that cannot be billed currently and therefore may be reflected as "costs and estimated earnings in excess of billings" in our balance sheet. See Note 1 – Description of Business and Summary of Significant Accounting Policies, under the section entitled Method of Accounting for Contracts of Notes to Consolidated Financial Statements in Item 15. Exhibits and Financial Statement Schedules. To the extent our actual recoveries with respect to unapproved change orders, contract disputes or claims are lower than our estimates, the amount of any shortfall will reduce our revenues and the amount of costs and estimated earnings in excess of billings recorded on our balance sheet, and could have a material effect on our working capital, results of operations and cash flows. Additionally, as we include unapproved change orders in our estimates of revenues and costs to complete a project, our profitability may be diluted via the percentage-of-completion method of accounting for contract revenues. Any delay caused by the extra work may also adversely impact the timely scheduling of other project work and our ability to meet specified contract milestone dates.

Increased regulation of the hospitality and gaming industry could reduce the number of future hospitality and gaming projects available, which, in turn, could adversely affect our future earnings.

The hospitality and gaming industry is regulated extensively by federal and state regulatory bodies, including state gaming commissions, the National Indian Gaming Commission and federal and state taxing and law enforcement agencies. From time to time, legislation is proposed in the legislatures of some of these jurisdictions that, if enacted, could adversely affect the tax, regulatory, operational or other aspects of the hospitality and gaming industry. Legislation of this type may be enacted in the future. New legislation or hospitality and gaming regulations could deter future hospitality and gaming construction projects in jurisdictions in which we derive significant revenues. As a result, the enactment of any such new legislation or regulations could adversely affect our future earnings.

Completing the integration of recent acquisitions into our Company may result in unforeseen operating difficulties and may require significant financial, operational and managerial resources that would otherwise be available for the operation, development and expansion of our existing business.

During 2011 we completed an acquisition strategy, in which we acquired Superior Gunite, Fisk, Anderson, Frontier-Kemper, Lunda, WDF, FSE, Nagelbush and Becho over a period of 10 months. To the extent that we experience unforeseen difficulties in completing the integration of these acquisitions, we may also have difficulty achieving our operating, strategic and financial objectives.

The percentage-of-completion method of accounting for contract revenues involved significant estimates which may result in material adjustments, which could result in a charge against our earnings.

We recognize contract revenues using the percentage-of-completion method. Under this method, estimated contract revenues are recognized by applying the percentage of completion of the project for the period to the total estimated revenues for the contract. Estimated contract losses are recognized in full when determined. Total contract revenues and cost estimates are reviewed and revised at a minimum on a quarterly basis as the work progresses and as change orders are approved. Adjustments based upon the percentage of completion are reflected in contract revenues in the period when these estimates are revised. To the extent that these adjustments result in an increase or a reduction in or an elimination of previously reported contract profit, we recognize a credit or a charge against current earnings, as applicable. Such credits or charges could be material and could cause our results to fluctuate materially from period to period.

Accounting for our contract related revenues and costs, as well as other expenses, require management to make a variety of significant estimates and assumptions. Although we believe we have the experience and processes to enable us to formulate appropriate assumptions and produce reasonably dependable estimates, these assumptions and estimates may change significantly in the future and could result in the reversal of previously recognized revenue and profit. Such changes could have a material adverse effect on our financial position and results of operations.

If we are unable to accurately estimate the overall risks, revenues or costs on a contract, we may achieve a lower than anticipated profit or incur a loss on that contract.

We generally enter into four principal types of contracts with our customers: fixed price contracts, cost plus fee contracts, guaranteed maximum price contracts, and construction management contracts. We derive a significant portion of our Civil, Specialty Contractors and Management Services segment revenues and backlog from fixed price contracts.

Fixed price and certain design-build contracts require us to perform the contract for a fixed price irrespective of our actual costs. As a result, we realize a profit on these contracts only if we successfully control our costs to avoid cost overruns and successfully negotiate change orders for out of scope work.

Cost plus fee contracts provide for reimbursement of the costs required to complete a project, but generally have a lower base fee and an incentive fee based on cost and/or schedule performance. If our costs exceed the revenues available under such a contract or are not allowable under the provisions of the contract, we may not receive reimbursement for these costs.

Guaranteed maximum price contracts provide for a cost plus fee arrangement up to a maximum agreed-upon price. These contracts also place the risk on us for cost overruns that exceed the guaranteed maximum price.

Construction management contracts are those under which we agree to manage a project for a customer for an agreed upon fee, which may be fixed or may vary based upon negotiated factors. Profitability on these types of contracts is impacted by changes in the scope of work or design issues, which could cause cost overruns beyond our control and limit profits on these contracts.

Cost overruns, whether due to inefficiency, faulty estimates or other factors, result in lower profit or even a loss on a project. If our estimates of the overall risks, revenues or costs prove inaccurate or circumstances change, we may incur a lower profit or a loss on that contract.

Table of Contents

We are subject to a number of risks as a U.S. government contractor, which could harm our reputation, result in fines or penalties against us and/or adversely impact our financial condition.

We are a provider of services to U.S. government agencies and therefore are exposed to risks associated with government contracting. We must observe laws and regulations relating to the formation, administration and performance of government contracts which affect how we do business with our U.S. government customers and may impose added costs on our business. For example, the Federal Acquisition Regulations allow our U.S. government customers to terminate our contracts for the failure to comply with regulatory requirements not directly related to performance and in certain cases, require us to disclose and certify cost and pricing data in connection with contract negotiations.

Our failure to comply with these or other laws and regulations could result in contract terminations, suspension or debarment from contracting with the U.S. government, civil fines and damages and criminal prosecution and penalties, any of which could cause our actual results to differ materially from those anticipated.

U.S. government agencies generally can terminate or modify their contracts with us at their convenience and some government contracts must be renewed annually at the U.S. government’s sole discretion. If a government agency terminates or fails to renew a contract, our backlog may be reduced. If a government agency terminates a contract due to our unsatisfactory performance, it could result in liability to us and harm our ability to compete for future contracts.

U.S. government agencies, including the Defense Contract Audit Agency, or DCAA, routinely audit our U.S. government contracts and contractors’ administration processes and systems. These agencies review our performance on contracts, pricing practices, cost structure and compliance with applicable laws, regulations and standards. They also review the adequacy of our internal control systems and policies, including our purchasing, property, estimating, and information systems. Only costs allowable under federal regulations may be properly charged to our government contracts and any costs found to be improperly allocated to a specific contract will not be reimbursed, and any such costs already reimbursed must be refunded or otherwise properly credited to the U.S. government in subsequent invoices. Moreover, if any of the administrative processes or systems is found not to comply with requirements, we may be subjected to increased government oversight and approval that could delay or otherwise adversely affect our ability to compete for or perform contracts. Therefore, an unfavorable outcome to an audit by the DCAA or another agency could cause our results to differ materially from those anticipated. If an investigation uncovers improper or illegal activities, we may be subject to civil and criminal penalties and administrative sanctions, including termination of contracts, forfeitures of profits, suspension of payments, fines and suspension or debarment from doing business with the U.S. government. In addition, we would suffer serious harm to our reputation if allegations of impropriety were made against us. Each of these results could cause actual results to differ materially from those anticipated.

Our pension plan is underfunded and we may be required to make significant future contributions to the plan.

Our defined benefit pension plan and our supplemental retirement plan are non-contributory pension plans covering many of our employees. Benefits under these plans were frozen as of June 1, 2004. As of December 31, 2012, these plans were underfunded by approximately $39.2 million. We are required to make cash contributions to our pension and supplemental retirement plans to the extent necessary to comply with minimum funding requirements imposed by employee benefit and tax laws. The amount of any such required contributions is determined based on an annual actuarial valuation of the plan as performed by the plans’ actuaries. During 2012, we contributed $5.8 million in cash to our defined benefit pension plan and supplemental retirement plan. The amount of our future contributions will depend upon asset returns, then-current discount rates and a number of other factors, and, as a result, the amount we may elect or be required to contribute to these plans in the future may vary significantly. See Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations under the section entitled Critical Accounting Policies.

In connection with mergers and acquisitions, we have recorded goodwill and other intangible assets that could become impaired and adversely affect our operating results. Assessing whether an impairment has occurred requires us to make significant judgments and assumptions about the future, which are inherently subject to risks and uncertainties, and if actual events turn out to be materially less favorable than the judgments we make and the assumptions we use, we may be required to record additional impairments in the future.

We had approximately $621.1 million of goodwill and indefinite-lived intangible assets recorded on our consolidated balance sheet at December 31, 2012. Goodwill represents the excess of cost over the fair value of net assets acquired in business combinations reduced by any impairments recorded subsequent to the date of acquisition. 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 or circumstances change which suggest that the goodwill or intangible assets should be evaluated. For example, if our market capitalization drops significantly below the amount of net equity recorded on our balance sheet, it might indicate a decline in the fair value of our goodwill and intangible assets and would require us to further evaluate whether an impairment has occurred. If we determine that there has been an impairment (meaning that carrying value exceeds fair value), we would be required to write down the carrying value by the amount of the excess (which would represent the impaired portion of these assets).

Impairment assessment inherently involves management judgments as to the assumptions used to project amounts included in the valuation process and as to anticipated future market conditions and their potential effect on future performance. Changes in assumptions or estimates can materially affect the determination of far value. If we determine, based on our assumptions, judgments, estimates and projections, that no impairment exists as of a specific date, and if future events turn out to be materially less favorable than what we assumed or estimated in assessing fair value when we tested for impairment, we may be required at a future date (either as part of a subsequent annual evaluation or on an interim basis) to re-evaluate fair value and to recognize an impairment at that time and write down the carrying value of our goodwill and/or indefinite-lived intangible assets. If we were required to write down all or a significant part of our goodwill and indefinite-lived intangible assets in future periods, our net earnings and equity could be materially and adversely affected.

The forecasts utilized in the discounted cash flow analysis as part of our impairment test assume future revenue and profitability growth in each of our segments. If our operating segments cannot obtain, or we determine at a later date that we no longer expect them to obtain, the projected levels of profitability, future goodwill impairment tests may also result in an impairment charge. There can be no assurances that our operating segments will be able to achieve our estimated levels of profitability. A number of factors, many of which we have no ability to control, could affect our financial condition, operating results and business prospects and could cause our actual results to differ from the estimates and assumptions we employed in our goodwill impairment testing. These factors include, but are not limited to, (i) further weakening in the overall economy; (ii) a significant decline in our stock price and resulting market capitalization; (iii) changes in the discount rate; (iv) successful efforts by our competitors to gain market share in our markets; (v) adverse changes as a result of regulatory actions; (vi) a significant adverse change in legal factors or in the overall business climate; (vii) recognition of a goodwill impairment loss in the financial statements of a subsidiary that is a component of our reporting units; and (viii) the resolution of legal proceedings resulting in judgments less favorable than our estimates. Given these and other factors, we cannot be certain that goodwill impairment will not be required during future periods.

In 2012, our interim review indicated that goodwill and other intangible assets were impaired, and we recorded a charge of $376.6 million in the second quarter of 2012 as discussed in Critical Accounting Policies in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations below. As a result, we incurred a significant loss in 2012 and stockholders’ equity declined by $256.0 million to $1.1 billion at December 31, 2012. Based on our annual review of our goodwill and intangible assets with indefinite lives, which we performed in the fourth quarter of 2012, we concluded that no additional impairment had occurred. The fair value of the Management Services segment exceeded its carrying value by 4.5% while the fair values of all other segments exceeded their carrying values by more than 10%. The carrying value of the goodwill of the Management Services segment was $44.2 million at December 31, 2012.

Conflicts of interest may arise involving certain of our directors.

We have engaged in joint ventures, primarily in civil construction, with O&G Industries, Inc., a Connecticut corporation, whose Vice Chairman is Raymond R. Oneglia, one of our directors. As of December 31, 2012, the Company had a 30% interest in a joint venture with O&G as the sponsor for a highway reconstruction project with an estimated total contract value of approximately $361 million and an estimated completion in 2017. In accordance with the Company’s policy, the terms of this joint venture and any of our joint ventures with any affiliate have been and will be subject to review and approval by our Audit Committee. As in any joint venture, we could have disagreements with our joint venture partner over the operation of a joint venture or a joint venture could be involved in disputes with third parties, where we may or may not have a conflict of interest with our joint venture partner. These relationships also may create conflicts of interest with respect to new business and other corporate opportunities.

Ronald N. Tutor’s ownership interest in the Company, along with his management position and his right to designate nominees to serve as members of our Board of Directors, provides him with significant influence over corporate matters and may make a third party’s acquisition of the Company (or its stock or assets) more difficult.

As of December 31, 2012, Mr. Tutor and two trusts controlled by Mr. Tutor (the “Tutor Group”) owned approximately 19.2% of the outstanding shares of our common stock. In addition, Mr. Tutor is the chairman and chief executive officer of the Company and has the right to designate one nominee for election as members of the Company’s Board of Directors so long as the Tutor Group owns at least 11.25% of the outstanding shares of the Company’s common stock. As of the date of this Form 10-K, none of the current directors have been appointed by Mr. Tutor. Mr. Tutor has advised the Board that should he choose to designate a person for appointment to the Board at a time when the Board already includes eleven members, he would support a temporary expansion of the Board to twelve members to accommodate such additional member. Pursuant to the Shareholders Agreement dated April 2, 2008 and amended by Amendments No. 1, 2, and 3 dated September 17, 2010, June 2, 2011 and September 13, 2011, respectively, by and among Tutor Perini Corporation, Mr. Tutor and certain shareholders of Tutor-Saliba Corporation signatory thereto (the “Amended Shareholders Agreement”) such expansion would continue until the next meeting of shareholders at which directors are elected, at which time the size of the Board would be reduced back to eleven members and the slate of nominees for election adjusted accordingly. The Amended Shareholders Agreement also imposes significant limits on Mr. Tutor’s right to vote the shares of our common stock held by the Tutor Group or to take specified actions that may facilitate an unsolicited acquisition of control of the Company by Mr. Tutor or his affiliates. Mr. Tutor will nonetheless still be able to exert significant influence over the outcome of a range of corporate matters, including significant corporate transactions requiring a shareholder vote, such as a merger or a sale of the Company or its assets. This concentration of ownership and influence in management and Board decision-making also could harm the price of our common stock by, among other things, discouraging a potential acquirer from seeking to acquire shares of our common stock (whether by making a tender offer or otherwise) or otherwise attempting to obtain control of the Company.

Our business, financial position, results of operations and cash flows could be adversely affected by work stoppages and other labor problems.

We are a signatory to numerous local and regional collective bargaining agreements, both directly and through trade associations. If we or our trade associations are unable to negotiate with any of our unions, we might experience strikes, work stoppages or increased operating costs as a result of higher than anticipated wages or benefits. If our unionized workers engage in a strike or other work stoppage, or our non-unionized employees become unionized, we could experience a disruption of our operations and higher ongoing labor costs, which could adversely affect our business, financial position, results of operations and cash flows.

We have a substantial amount of indebtedness which could adversely affect our financial position and prevent us from fulfilling our obligations under our debt agreements, in particular under our $300 million senior unsecured notes and our $200 million term loan under our revolving credit facility.

We currently have and expect to continue to have a substantial amount of indebtedness. As of December 31, 2012, we had a total debt of $737.1 million, consisting of $298.3 million of senior unsecured notes (net of unamortized debt discount of $1.7 million) (the “Senior Notes”), $120.0 million of outstanding borrowings on a revolving credit basis (the “Revolving Facility”), a $200 million term loan (the “Term Loan”) which has been paid down to $152.5 million at December 31, 2012, and $166.3 million of other debt. We may also incur significant additional indebtedness in the future. Our substantial indebtedness may:

make it difficult for us to satisfy our financial obligations, including making scheduled principal and interest payments on the Senior Notes, Term Loan and our other indebtedness;

limit our ability to borrow additional funds for working capital, capital expenditures, acquisitions or other general business purposes;

limit our ability to use our cash flow or obtain additional financing for future working capital, capital expenditures, acquisitions or other general business purposes;

require us to use a substantial portion of our cash flow from operations to make debt service payments;

limit our flexibility to plan for, or react to, changes in our business and industry;

place us at a competitive disadvantage compared to our less leveraged competitors; and

increase our vulnerability to the impact of adverse economic and industry conditions.

We are subject to restrictive covenants under our revolving credit facility and the indenture for our $300 million senior unsecured notes that could limit our flexibility in managing the business.

Our revolving credit facility imposes operating and financial restrictions on us. These restrictions include, among other things, limitations on our ability to:

create liens or other encumbrances;

enter into certain types of transactions with our affiliates;

make certain capital expenditures;

make investments, loans or other guarantees;

sell or otherwise dispose of a portion of our assets; or

merge or consolidate with another entity.

In addition, our revolving credit facility limits our ability to incur indebtedness from other sources without the consent of our lenders. Our revolving credit facility contains financial covenants that require us to maintain minimum net worth, minimum fixed charge coverage and maximum leverage ratios. Our ability to borrow funds for any purpose is dependent upon satisfying these tests.

Table of Contents

Our Senior Notes also impose operating and financial restrictions on us including, among other things, the following limitations on our ability to:

incur additional indebtedness or issue certain preferred stock;

pay dividends on, or make distributions in respect of, our capital stock or repurchase our capital stock;

make certain investments or other restricted payments;

sell certain assets;

create liens or use assets as security in other transactions;

merge, consolidate or transfer or dispose of substantially all of their assets; or

engage in certain transactions with affiliates

If we are unable to meet the terms of the financial covenants or fail to comply with any of the other restrictions contained in these agreements, an event of default could occur. An event of default, if not waived by our lenders, could result in an acceleration of any outstanding indebtedness, causing such debt to become immediately due and payable. If such an acceleration occurs, we may not be able to repay such indebtedness on a timely basis. Since indebtedness under our revolving credit facility and Senior Notes is secured by substantially all of our assets, acceleration of this debt could result in foreclosure of those assets. In the event of a foreclosure, we would be unable to conduct our business and may be forced to discontinue ongoing operations.

Funds associated with auction rate securities may not be liquid or readily available.

As discussed in Note 3 – Fair Value Measurements of Notes to Consolidated Financial Statements in Item 15. Exhibits and Financial Statement Schedules, our investment securities primarily consist of auction rate securities which are not currently liquid or readily available to convert to cash. As of December 31, 2012 and 2011, respectively, we held $46.3 million and $62.3 million in auction rate securities. In conjunction with our estimates of fair value at December 31, 2011 and 2010, we deemed our investment in auction rate securities to be impaired by $4.8 million and $5.7 million in 2011 and 2010, respectively. These impairment charges were deemed to be other-than-temporary, thereby resulting in charges to income. In 2012, we did not deem any of our auction rate securities to be impaired, however, the settlement of three securities in 2012 resulted in a realized loss of $2.7 million. If the auction rate securities market continues to remain relatively illiquid, it is possible that we will be required to further adjust the fair value of our auction rate securities. If we determine that the decline in the fair value of our auction rate securities is other-than-temporary, it would result in additional impairment charges being recognized in our Consolidated Statements of Operations, which could be material and which could adversely affect our financial results. In addition, the lack of liquidity associated with these investments may require us to access our revolving credit facility until some or all of our auction rate securities are liquidated.

We retain a certain level of self-insured risk for workers’ compensation, general liability, automobile liability and subcontractor default insurance. Therefore, large self-insured losses, associated with several insurable events, could adversely affect our operating results.

We self-insure for a portion of our claims exposure resulting from workers' compensation, general liability, automobile liability and certain events of subcontractor default. We maintain insurance coverage with licensed insurance carriers which limits our aggregate exposure to excessive loss experience in a given policy year. In addition, we maintain insurance coverage above the amounts for which we self-insure. We accrue currently for estimated incurred losses and expenses, and periodically evaluate and adjust our claims accrued liability to reflect our experience. However, if excessive loss experience should occur in a policy year or years, ultimate results may differ materially from our estimates, which could adversely affect our operating results and cash flow. Although we believe the level of our insurance coverage should be sufficient to cover reasonably expected claims, it is possible that one or more claims could exceed our aggregate coverage limits. Also, there are some types of losses such as from hurricanes, terrorism, wars, or earthquakes where insurance is limited and/or not economically justifiable. If an uninsured loss occurs, it could adversely affect our operating results and cash flow.

Changes to our information systems as well as any loss, breach of security, disruption, unexpected data or our inability to implement new systems, could have a material adverse effect on our business.

We rely on third-party software to run critical accounting, project management and financial information systems. If software vendors decide to discontinue further development, integration or long-term software maintenance support for our information systems, or there is any system interruption, delay, breach of security, loss of data or loss of a vendor, we may need to migrate some or all of our accounting, project management and financial information to other systems. These disruptions could increase our operational expense as well as impact the management of our business operations, which could have a material adverse effect on our financial position, results of operations, cash flows and liquidity.

ITEM 3. LEGAL PROCEEDINGS

Legal Proceedings are set forth in our financial statement schedules in Part IV, Item 15 of this Annual Report and are incorporated herein by reference. See Note 9 – Contingencies and Commitments of Notes to Consolidated Financial Statements of Part IV, Item 15. Exhibits and Financial Statement Schedules.

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, however, we may be treated as acting as a mining operator as defined under the Mine Act because we are 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. For 2012, revenues from services and construction of a mine were less than $100 million.

Holders

At February 20, 2013, there were 686 holders of record of our common stock, including holders of record on behalf of an indeterminate number of beneficial owners, based on the stockholders list maintained by our transfer agent.

Dividends

On October 25, 2010 our Board of Directors declared a special cash dividend of $1.00 per share of common stock. The dividend was paid on November 12, 2010 to stockholders of record on November 4, 2010. Prior to the special cash dividend paid in 2010, we had not paid any cash dividends on our common stock since 1990, and we currently have no future plans to pay cash dividends. Our revolving facility and senior unsecured notes also restrict us from making dividend payments. See Note 5 – Financial Commitments of Notes to Consolidated Financial Statements in Part IV, Item 15. Exhibits and Financial Statements Schedules.

Performance Graph

The following graph compares the cumulative 5-year total return to shareholders on our common stock relative to the cumulative total returns of the New York Stock Exchange Composite Index (“NYSE”) and the Dow Jones Heavy Construction Index (“DJ Heavy Construction”). We selected the DJ Heavy Construction because we believe the index reflects the market conditions within the industry, in which we primarily operate. The comparison of total return on investment, defined as the change in year-end stock price plus reinvested dividends, for each of the periods assumes that $100 was invested on December 31, 2007, in each of our common stock, the NYSE and the DJ Heavy Construction, with investment weighted on the basis of market capitalization.

The comparisons in the following graph are based on historical data and are not intended to forecast the possible future performance of our common stock.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

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 customers 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 to 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. We continued to experience increased contributions from our Civil and Specialty Contractor segments consistent with our focus on obtaining higher margin public works projects and enhancing our self-performance capabilities. We expect to continue to leverage our increased self-performance and schedule control capabilities to obtain additional large scale Civil and Building awards. We have capitalized on this leadership position and these synergies with significant new awards and pending awards across each of our segments, such as the $235 million Verrazano-Narrows Bridge upper deck replacement project in New York City (Civil); the $167 million signal modernization project for the New York City Transit Authority (Specialty Contractors); the $130 million irrigation and watershed management program for the U.S. government (Management Services); and several large pending awards for the Hudson Yards development project in New York City (Building), which will be booked into backlog as contracts for various phases are executed and work is released.

We have also experienced a shift in the stage of completion of our portfolio of large projects that significantly drive our operating results. As we entered into 2012, we had realized the benefits of successfully completing and closing out several large public works and hospitality and gaming projects across our Building, Civil and Specialty Contractor segments and we replaced several of the large projects discussed above with mid-size awards that are in earlier stages of completion. We continue our strategic focus on growing our business by pursuing and obtaining large complex public works projects.

During 2012, we recorded revenues of $4.1 billion, loss from construction operations of $221.8 million and net loss of $265.4 million, or $5.59 per diluted share as compared to revenues of $3.7 billion, income from construction operations of $168.4 million and net income of $86.1 million, or $1.80 per diluted share during 2011.

Our revenues increased during 2012 by 10.6% primarily due to the full year contributions from our 2011 acquisitions, partially offset by a decline in our Building segment associated with the substantial completion of several large public works and hospitality and gaming projects in 2011.

Our gross profit increased in 2012 by 5.0% due to the reasons discussed above, partly offset by an unfavorable new work margin mix. Despite recent positive trends in the construction market, the current economic environment continues to provide for slower than expected release of large building and civil projects, which have resulted in delayed revenue opportunities and continued margin pressure.

Our general and administrative expenses increased in 2012 by 14.7% primarily due to the full-year impact of our 2011 acquisitions.

Our loss from construction operations of $221.8 million in 2012 was materially impacted by a $376.6 million goodwill and intangible asset impairment charge ($326.4 million after-tax), as discussed in further detail under Critical Accounting Policies below. Excluding the impact of the impairment charge, our results from construction operations decreased $13.6 million primarily due to the substantial completion of large projects discussed above and an unfavorable change in new work margin mix, partially offset by the full year contributions from our 2011 acquisitions.

Table of Contents

Our interest expense increased from $35.8 million in 2011 to $44.2 million in 2012 primarily due to additional borrowings to fund operations and to complete the 2011 acquisitions.

Our income tax expense decreased from a $50.9 million expense in 2011 to an income tax benefit of $2.4 million in 2012 primarily due to the reasons discussed above. The income tax benefit in 2012 includes the impact of a $50.2 million reduction in our provision for income taxes recorded due to the $376.6 million goodwill and intangible asset impairment charges, and a $3.6 million increase to our provision for income taxes due to discrete tax adjustments.

In 2012, we received significant new contract awards, as well as additions to existing contracts, and ended the year with a contract backlog of $5.6 billion, a decrease of $0.5 billion from $6.1 billion as of December 31, 2011. The decrease was due to reduced backlog in our Building and Civil segments associated with continued activity on several large healthcare facility projects and certain tunnel projects on the West Coast, partially offset by increased backlog in our Specialty Contractors and Management Services segments associated with new recent project awards.

At December 31, 2012, we had working capital of $747.6 million, a ratio of current assets to current liabilities of 1.61 to 1.00, and a ratio of debt to equity of 0.64 to 1.00, 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 debt to equity of 0.48 to 1.00 at December 31, 2011. These results reflect the additional leverage we took on during 2011 to finance our acquisition strategy. Our stockholders’ equity decreased to $1.1 billion as of December 31, 2012 from $1.4 billion as of December 31, 2011. The increase in our debt to equity ratio and the decrease in our stockholders’ equity at December 31, 2012 compared to December 31, 2011 primarily reflect the impact of the $376.6 million goodwill and intangible asset impairment charge ($326.4 million after-tax) recorded during the second quarter of 2012.

Non-GAAP Measures

Our consolidated financial statements are presented based on accounting principles generally accepted in the United States (“U.S. 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, prospective investors and others. These non-GAAP 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

Hudson Yards Project Breaks Ground on South Tower (Tower C)

In January 2012, we announced that we had been retained by Related Companies and Oxford Properties Group as general contractor for the Hudson Yards Development in midtown Manhattan (“Hudson Yards”). We were also retained for the construction of a residential tower being developed just south of Hudson Yards on 30th Street and 10th Avenue in New York City. Hudson Yards is a 26-acre mixed-use development accommodating over 13 million square feet of commercial and residential space. The master plan comprises approximately 5,000 residences, 6 million square feet of state-of-the-art commercial office space, a 1 million square-foot destination retail center with an over 130,000 square-foot two-level space of specialty destination restaurants, cafes, markets and bars, a five-star hotel, a unique cultural space, and a new 750-seat school, all carefully planned around 14 acres of public open space. Pre-construction activities related to the 30th Street residential tower began in early 2012 and substantial completion is expected in the spring of 2014. The total construction value of the 30th Street residential tower project is approximately $125 million. Physical construction operations at the Hudson Yards South Tower (Tower C), located across the street from the 30th Street residential tower, began in December 2012 and substantial completion is expected in late 2015. The total construction value of the South Tower phase of the project is approximately $800 million.

The Hudson Yards project will be booked into backlog as contracts for various phases are executed and work is released. It is likely that our backlog and eventual revenues associated with the various phases of our work at Hudson Yards may be significantly lower than the total construction value of each phase because the type of contracts for each phase may initially be construction management not at risk, whereby our backlog and revenues would be reported excluding external subcontractor progress. However, our profits related to each phase will be based on the total construction value, including the externally subcontracted portions. There may be provisions within each contract to allow our customer to convert from a construction management not at risk contract to a guaranteed maximum price contract. If such a conversion were to occur, the Company would then recognize the full construction value for each phase of the project as backlog and revenue.

Backlog Analysis for 2012

Our backlog of uncompleted construction work at December 31, 2012 was approximately $5.6 billion, as compared to $6.1 billion at December 31, 2011. Significant new awards included a $235 million bridge rehabilitation project, a $181 million hospitality and gaming project, a $167 million transit signal modernization project, a $130 million irrigation and watershed management program, a $116 million joint venture bridge and highway 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.

The following table provides an analysis of our backlog by business segment for the year ended December 31, 2012.

New business awarded consists of the original contract price of projects added to our backlog plus or minus subsequent changes to the estimated total contract price of existing contracts.

Critical Accounting Policies

Our accounting and financial reporting policies are in conformity with U.S. GAAP. The preparation of our consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the balance sheet date, and the reported amounts of revenues and expenses during the reporting period. Although our significant accounting policies are described in Note 1 – Description of Business and Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements in Part IV, Item 15. Exhibits and Financial Statement Schedules, the following discussion is intended to describe those accounting policies most critical to the preparation of our consolidated financial statements.

Use of and Changes in Estimates - The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Our construction business involves making significant estimates and assumptions in the normal course of business relating to our contracts and our joint venture contracts due to, among other things, the one-of-a-kind nature of most of our projects, the long-term duration of our contract cycle and the type of contract utilized. Therefore, management believes that the “Method of Accounting for Contracts” is the most important and critical accounting policy. The most significant estimates with regard to these financial statements relate to the estimating of total forecasted construction contract revenues, costs and profits in accordance with accounting for long-term contracts (see Note 1 – Description of Business and Summary of Significant Accounting Policies, under the section entitled (d)Use of and Changes in Estimates of the Notes to Consolidated Financial Statements in Part IV, Item 15. Exhibits and Financial Statement Schedules) and estimating potential liabilities in conjunction with certain contingencies, including the outcome of pending or future litigation, arbitration or other dispute resolution proceedings relating to contract claims (see Note 9 – Contingencies and Commitments of the Notes to Consolidated Financial Statements in Part IV, Item 15. Exhibits and Financial Statement Schedules). Actual results could differ from these estimates and such differences could be material.

Table of Contents

Our estimates of contract revenue and cost are highly detailed. We believe that, based on our experience, our current systems of management and accounting controls allow us to produce materially reliable estimates of total contract revenue and cost during any accounting period. However, many factors can and do change during a contract performance period which can result in a change to contract profitability from one financial reporting period to another. Some of the factors that can change the estimate of total contract revenue and cost include differing site conditions (to the extent that contract remedies are unavailable), the availability of skilled contract labor, the performance of major material suppliers to deliver on time, the performance of major subcontractors, unusual weather conditions and the accuracy of the original bid estimate. Because we have many contracts in process at any given time, these changes in estimates can offset each other minimizing the impact on overall profitability. However, large changes in cost estimates on larger, more complex construction projects can have a material impact on our financial statements and are reflected in our results of operations when they become known.

Management focuses on evaluating the performance of contracts individually. 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 year ended December 31, 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. 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 $7.5 million increase in our net income and a $0.16 increase in our diluted earnings per common share during 2012.

Contracts vary in lengths and larger contracts can span over three to four years. At various stages of a contract’s life cycle, different types of changes in estimates are more typical. Generally during the early ramp up stage, cost estimates relating to purchases of materials and subcontractors are frequently subject to revisions. As a contract moves into the most productive phase of execution, change orders, project cost estimate revisions and claims are frequently the sources for changes in estimates. During the contract’s final phase, remaining estimated costs to complete or provisions for claims will be closed out and adjusted based on actual costs incurred. The impact on operating margin in a reporting period and future periods from a change in estimate will depend on the stage of contract completion. Generally, if the contract is at an early stage of completion, the current period impact is smaller than if the same change in estimate is made to the contract at a later stage of completion. Likewise, if the company’s overall project portfolio was to be at a later stage of completion during the reporting period, the overall gross margin could be subject to greater variability from changes in estimates.

When recording revenue on contracts relating to unapproved change orders and claims, we include in revenue an amount less than or equal to the amount of costs incurred by us to date for contract price adjustments that we seek to collect from customers for delays, errors in specifications or designs, change orders in dispute or unapproved as to scope or price, or other unanticipated additional costs, in each case when recovery of the costs is considered probable. The amount of unapproved change orders and claim revenues is included in our Consolidated Balance Sheets as part of costs and estimated earnings in excess of billings. When determining the likelihood of eventual recovery, we consider such factors as evaluation of entitlement, settlements reached to date and our experience with the customer. The settlement of these issues may take years depending upon whether the item can be resolved directly with the customer or involves litigation or arbitration. When new facts become known, an adjustment to the estimated recovery is made and reflected in the current period results.

Method of Accounting for Contracts – Revenues and profits from our contracts and construction joint venture contracts are recognized by applying percentages of completion for the period to the total estimated revenues for the respective contracts. Percentage of completion is determined by relating the actual cost of the work performed to date to the current estimated total cost of the respective contracts. When the estimate on a contract indicates a loss, the entire loss is recorded during the accounting period in which it is estimated. In the ordinary course of business, at a minimum on a quarterly basis, we prepare updated estimates of the total forecasted revenue, cost and profit or loss for each contract. The cumulative effect of revisions in estimates of the total forecasted revenue and costs, including unapproved change orders and claims, during the course of the work is reflected in the accounting period in which the facts that caused the revision become known. The financial impact of these revisions to any one contract is a function of both the amount of the revision and the percentage of completion of the contract. An amount up to the costs incurred that are attributable to unapproved change orders and claims is included in the total estimated revenue when realization is probable. For a further discussion of unapproved change orders and claims, see Item 1. Business under the section entitled Types of Contracts and The Contract Process and Item 1A. Risk Factors. Profit from unapproved change orders and claims is recorded in the accounting period in which such amounts are resolved.

Table of Contents

Billings in excess of costs and estimated earnings represents the excess of contract billings to date over the amount of contract costs and profits (or contract revenue) recognized to date on the percentage of completion accounting method. Costs and estimated earnings in excess of billings represents the excess of contract costs and profits (or contract revenue) recognized to date on the percentage of completion accounting method over contract billings to date. Costs and estimated earnings in excess of billings results when (1) the appropriate contract revenue amount has been recognized in accordance with the percentage of completion accounting method, but a portion of the revenue recorded cannot be billed currently due to the billing terms defined in the contract and/or (2) costs, recorded at estimated realizable value, related to unapproved change orders or claims are incurred. For unapproved change orders or claims that cannot be resolved in accordance with the normal change order process as defined in the contract, we may employ other dispute resolution methods, including mediation, binding and non-binding arbitration, or litigation. See Item 3. Legal Proceedings and Note 9 - Contingencies and Commitments of the Notes to Consolidated Financial Statements in Part IV, Item 15. Exhibits and Financial Statement Schedules. The prerequisite for billing unapproved change orders and claims is the final resolution and agreement between the parties. Costs and estimated earnings in excess of billings related to our contracts and joint venture contracts at December 31, 2012 is discussed above under “Use of and Changes in Estimates” and in Note 1 - Description of Business and Summary of Significant Accounting Policies of Notes to Consolidated Financial Statements in Part IV, Item 15. Exhibits and Financial Statement Schedules.

Impairment of Goodwill and Other Intangible Assets - Intangible assets with finite lives are amortized over their useful lives. Construction contract backlog is amortized on a weighted average basis over the corresponding contract period. Customer relationships and certain trade names are amortized on a straight-line basis over their estimated useful lives. Goodwill and intangible assets with indefinite lives are not amortized. We evaluate intangible assets that are not being amortized at the end of each reporting period to determine whether events and circumstances continue to support an indefinite useful life.

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 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 primarily based 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 customer 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.

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 it 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 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.

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 for projections and to evaluate 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 are 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.

Table of Contents

Weighted average cost of capital rates used to discount the projected cash flows are 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 are 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 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.

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 its goodwill evaluation, we also evaluated its 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 the Company’s trade name, contractor license, customer relationship and contract backlog intangible assets that were recorded in previous acquisitions).

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, 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.

Table of Contents

Consistent with our expectations and as a result of the goodwill impairment charge we recognized in the second quarter of 2012 the fair value of the Management Services reporting unit exceeded its carrying value, including goodwill of $44.2 million, by 4.5%, while the fair values of the Building, Civil and Specialty Contractors reporting units exceeded their carrying values by more than 10%. Since the interim goodwill impairment test as of June 30, 2012, our annual impairment test, performed in the fourth quarter of 2012, did not indicate any further adjustment to goodwill. Should some of our assumptions not materialize, for example the projected future cash flows for the Management Services reporting unit in connection with anticipated ramp-up of work associated with additional troops moving to Guam, additional impairment of up to $44.2 million may negatively impact future earnings.

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;

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.

Fair Value Measurements – Our investment in auction rate securities (“ARS”) is measured at fair value utilizing unobservable (Level 3) inputs. We have determined the estimated fair values of these securities utilizing an income approach valuation model, with consideration given to market-based valuation inputs such as current market conditions, including repayment status of student loans, credit market risk, market liquidity and macro-economic influences. In addition, we obtained an independent valuation of some of our auction rate security instruments and considered these valuations in determining the estimated fair values of the auction rate securities in our portfolio. Our analyses considered, among other items, the collateralization underlying the security investments, the expected future cash flows, including the final maturity, associated with the securities, and estimates of the next time the security is expected to have a successful auction or return to full par value. See Note 1 - Description of Business and Summary of Significant Accounting Policies of Notes to Consolidated Financial Statements in Part IV, Item 15. Exhibits and Financial Statement Schedules for a detailed discussion of the fair market value assessment of our investment in ARS.

At December 31, 2012, the carrying value of our investment in auction rate securities approximated fair value.

The contingent consideration involved in the purchases of several of our recently acquired entities is also measured at fair value utilizing unobservable (Level 3) inputs. We estimate these fair values 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. See Notes 3 - Fair Value Measurements of Notes to Consolidated Financial Statements in Part IV, Item 15. Exhibits and Financial Statement Schedules for more information on our investment in ARS and contingent consideration.

Share-based Compensation - We have granted restricted stock units and stock options to certain employees and non-employee directors. We recognize share-based compensation expense net of an estimated forfeiture rate and only recognize compensation expense for those shares expected to vest on a straight-line basis over the requisite service period of the award (which corresponds to the vesting period). Determining the appropriate fair value model and calculating the fair value of stock option awards requires the input of highly subjective assumptions, including the expected life of the stock option awards and the expected volatility of our stock price over the life of the awards. We used the Black-Scholes-Merton option pricing model to value our stock option awards, and utilized the historical volatility of our common stock as a reasonable estimate of the future volatility of our common stock over the expected life of the awards. The assumptions used in calculating the fair value of share-based payment awards represent our best estimates, but these estimates involve inherent uncertainties and the application of management’s judgment. As a result, if factors change which require the use of different assumptions, share-based compensation expense could be materially different in the future. In addition, if the actual forfeiture rate is materially different from our estimate, share-based compensation expense could be significantly different from what has been recorded through December 31, 2012.

Insurance Liabilities – We assume the risk for the amount of the self-insured deductible portion of the losses and liabilities primarily associated with workers' compensation, general liability and automobile liability coverage. Losses are accrued based upon our estimates of the aggregate liability for claims incurred using historical experience and certain actuarial assumptions followed in the insurance industry. The estimate of our insurance liability within our self-insured deductible limits includes an estimate of incurred but not reported claims based on data compiled from historical experience. Actual experience could differ significantly from these estimates and could materially impact our consolidated financial position and results of operations. We purchase varying levels of insurance from third parties, including excess liability insurance, to cover losses in excess of our self-insured deductible limits. Currently, our self-insured deductible limit for workers' compensation, general liability and automobile coverage is generally $1.0 million per occurrence, subject to a policy aggregate loss limitation based upon policy exposures. In addition, on certain projects, we assume the risk for the amount of the self-insured deductible portion of losses and a co-payment amount that arise from any subcontractor defaults. Our self-insured deductible limit for subcontractor default on projects covered under our program ranges from $0.5 million to $2.0 million per occurrence, with a co-payment of 20% of the next $5.0 million, subject to an annual aggregate ranging from $3.5 million to $4.0 million.

Accounting for Income Taxes – Information relating to our provision for income taxes and the status of our deferred tax assets and liabilities is presented in Note 6 - Income Taxes of the Notes to Consolidated Financial Statements in Part IV. Item 15. Exhibits and Financial Statement Schedules A key assumption in the determination of our book tax provision is the amount of the valuation allowance, if any, required to reduce the related deferred tax assets. The net deferred tax assets reflect management’s estimate of the amount which will, more likely than not, reduce future taxable income.

Our accounting policy requires us to identify and review potential tax uncertainties for tax positions taken or expected to be taken in a tax return and determine whether the exposure to those uncertainties have a material impact on our results of operations or financial condition as of December 31, 2012.

Defined Benefit Retirement Plan – The status of our defined benefit pension plan obligations, related plan assets and cost is presented in Note 8 - Employee Benefit Plans of the Notes to Consolidated Financial Statements in Part IV. Item 15. Exhibits and Financial Statement Schedules. Plan obligations and annual pension expense are determined by actuaries using a number of key assumptions which include, among other things, the discount rate and the estimated future return on plan assets. The discount rate of 4.10% used for purposes of computing the 2012 annual pension expense was determined at the beginning of the calendar year based upon an analysis performed by our actuaries which matches the cash flows of our plan’s projected liabilities to bond investments of similar amounts and durations. We plan to change the discount rate used for computing the 2013 annual pension expense to 3.58% based upon a similar analysis by our actuaries.

The estimated return on plan assets is primarily based on historical long-term returns of equity and fixed income markets according to our targeted allocation of plan assets (90% equity, 5% fixed income and 5% cash). We plan to use a return on asset rate of 6.75% in 2013 based on projected equity performance compared to long-term historical averages.

The plans’ benefit obligations exceeded the fair value of plan assets on December 31, 2012 and 2011 by $39.2 million and $38.6 million, respectively. Accordingly, we recorded adjustments to our pension liability with an offset to accumulated other comprehensive income (loss), a component of stockholders’ equity.

Effective June 1, 2004, all benefit accruals under our pension plan were frozen; however, the vested benefit was preserved. Due to the expected increase in amortization of prior years’ investment losses, we anticipate that pension expense will increase from $4.7 million in 2012 to $5.4 million in 2013. Cash contributions to our defined benefit pension plan are anticipated to be approximately $1.7 million in 2013. Cash contributions may vary significantly in the future depending upon asset performance and the interest rate environment.

Results of Operations -

2012 Compared to 2011

For the year ended December 31, 2012, we recorded revenues of $4,111.5 million, loss from construction operations of $221.8 million and net loss of $265.4 million as compared to revenues of $3,716.3 million, income from construction operations of $168.4 million and net income of $86.1 million for 2011. Basic and diluted loss per common share for 2012 were $5.59 and $5.59, respectively, as compared to basic and diluted earnings per common share of $1.82 and $1.80, respectively, for 2011. Excluding the impact of the discrete items discussed above in Non-GAAP Measures, we would have had income from construction operations and net income of $159.8 million and $70.3 million, respectively, and diluted earnings per common share of $1.46 in 2012.

Total Revenues	$	4,111.5	$	3,716.3	$	395.2			10.6	%

Building segment revenues decreased by $357.6 million (or 19.6%) from $1,825.5 million in 2011 to $1,467.9 million in 2012, primarily due to the substantial completion of a large public works project and a large hospitality and gaming project in 2011. These decreases were partially offset by increased activity in certain healthcare facility, office facility, and courthouse projects.

Civil segment revenues increased by $363.1 million (or 41.0%), from $885.2 million in 2011 to $1,248.3 million in 2012, primarily due to the acquisitions of Frontier-Kemper, Lunda and Becho in mid-2011 which contributed approximately $601.9 million to 2012 revenues in the aggregate, an increase of $259.6 million, or 75.8%, from their partial-year contributions of $342.3 million to 2011 revenues. Civil segment revenues also increased due to increased activity in certain tunnel projects on the West Coast and several highway projects on the East Coast that were awarded in 2011.

Specialty Contractors segment revenues increased by $380.5 million (or 47.4%), from $802.5 million in 2011 to $1,183.0 million in 2012, primarily due to the acquisition of FSE, WDF and Nagelbush in mid-2011 which contributed approximately $827.9 million to 2012 revenues in the aggregate, an increase of approximately $367.9 million, or 80.0%, from their partial-year contributions of $460.0 million to 2011 revenues.

Management Services segment revenues increased by $9.2 million (or 4.5%), from $203.1 million in 2011 to $212.3 million in 2012, primarily due to increased activity on several smaller awards in 2012.

(Loss) income from construction operations	$	(221.8	)				$	168.4

The following discussion of income (loss) from construction operations for the years ended December 31, 2012 and 2011 has been prepared on a pre-impairment charge basis in order to better compare normal operating results of each segment between the two fiscal years. Since the impairment charge impacts 2012 only and does not affect revenues, cost of revenues or general and administrative expenses we incur to conduct our day-to-day construction operations, management believes the following discussion, analysis and comparison of 2012 and 2011 operating results is more meaningful.

Building segment income from construction operations on a pre-impairment charge basis decreased by $50.4 million (or 108.9%), from operating income of $46.3 million in 2011 to an operating loss of $4.1 million in 2012, primarily due to the decline in volume discussed above under Revenues, and certain additional costs incurred on an educational facility in 2012. Building segment operating margin declined from 2.5% in 2011 to (0.3)% in 2012 primarily due to the higher margin contribution of a large public works completed in 2011, several favorable cost estimate adjustments realized in the close out stage of certain large hospitality and gaming projects in 2011, sustained general and administrative expenses as we awaited the start-up of several large pending projects, and an unfavorable change in new work margin mix as we have experienced an underlying change in the mix of our backlog from public to the private market.

Table of Contents

Civil segment income from construction operations on a pre-impairment charge basis increased by $34.0 million (or 43.3%), from $78.6 million in 2011 to $112.6 million in 2012, primarily due to the contributions from our 2011 acquisitions of approximately $60.0 million, an increase of $30.3 million, or 102.0%, from their partial year contributions of $29.7 million in 2011 as well as the increased volume discussed above under Revenues. This increase was partially offset by the substantial completion and favorable close out of certain large public works projects on the East Coast in 2011. Civil segment operating margin increased from 8.9% in 2011 to 9.0% in 2012 primarily due to better than expected winter weather conditions and equipment mobilization savings on several highway and bridge projects in the mid-West, increased contributions and activity on a higher margin public works tunnel project on the West Coast offset by a $5.0 million litigation provision relating to an adverse court decision.

Specialty Contractors segment income from construction operations on a pre-impairment charge basis increased by $13.5 million (or 20.6%), from $65.6 million in 2011 to $79.1 million in 2012, primarily due to the acquisitions discussed above, which contributed approximately $71.6 million in income from construction operations in the aggregate, an increase of $13.9 million, or 24.1% from their partial year contributions of $57.7 million in 2011. Specialty Contractor segment operating margin declined from 8.2% in 2011 to 6.7% in 2012 primarily due to the substantial completion of a large hospitality and gaming project with a high margin contribution in 2011 as well as increased cost estimates related to several smaller electrical projects in 2012.

Management Services segment income from construction operations on a pre-impairment charge basis decreased by $10.0 million (or 44.8%), from $22.3 million in 2011 to $12.3 million in 2012, primarily due to an increased competitive environment in 2012 and the substantial completion and favorable close out of certain projects in Iraq in 2011. Management Services segment operating margin declined from 11.0% in 2011 to 5.8% in 2012 primarily due to the above mentioned reasons as well as to an unfavorable change in new work margins.

Corporate general and administrative expenses were relatively flat at $45.1 million in 2012 compared to $44.4 million in 2011.

(Benefit) Provision for Income Taxes		(2.4	)		50.9		(53.3	)		(104.7	)%

Other income (expense), net, decreased by $6.3 million, from income of $4.4 million in 2011 to expense of $1.9 million in 2012, primarily due to a net increase of $0.3 million in certain business acquisition related liabilities in 2012, compared to a net reduction of $7.3 million in certain business acquisition related liabilities in 2011.

Interest expense increased by $8.4 million from $35.8 million in 2011 to $44.2 million in 2012 primarily due to additional borrowings to fund operations and to complete the 2011 acquisitions.

We recognized an income tax benefit of $2.4 million in 2012 as compared to an income tax expense of $50.9 million in 2011 primarily due to the goodwill and intangible impairment charge discussed above. The effective tax rate decreased from 37.1% in 2011 to 0.9% in 2012 primarily due to the impact of the impairment charge.

Results of Operations -

2011 Compared to 2010

For the year ended December 31, 2011, we recorded revenues of $3,716.3 million, income from construction operations of $168.4 million and net income of $86.1 million as compared to revenues of $3,199.2 million, income from construction operations of $172.3 million and net income of $103.5 million for 2010. Basic and diluted earnings per common share for 2011 were $1.82 and $1.80, respectively, as compared to $2.15 and $2.13, respectively, for 2010. Consistent with our strategy of focusing on higher margin public works projects and expanding our civil and specialty contracting presence, we experienced continued growth in the contributions from both our Civil and Specialty Contractors segments. Our legacy Building and Civil segment operating results primarily reflect the substantial completion of several successful, large public works projects as well as the start-up of several new public works projects in the eastern and western United States. Our Management Services segment continues its focus on obtaining new work with various U.S government agencies, including the U.S. military, both domestically and abroad. Our operating results decreased in 2011 primarily due to the substantial completion of several successful, large public works projects, and increased interest expense associated with our $300 million senior unsecured notes, $200 million term loan and borrowings under our revolving facility, offset by contributions from the recent acquisitions we have closed.

Revenues

*NM – Not Meaningful

Building segment revenues decreased by $398.0 million (or 17.9%) from $2,223.5 million in 2010 to $1,825.5 million in 2011, primarily due to the substantial completion of large hospitality and gaming and public works projects in Las Vegas and Philadelphia. This decrease was offset by the acquisition of Anderson which contributed $339.7 million in 2011.

Civil segment revenues increased by $218.1 million (or 32.7%), from $667.1 million in 2010 to $885.2 million in 2011, primarily due to the recent acquisitions which contributed approximately $342.3 million in revenues in the aggregate, offset by the substantial completion of projects in the metropolitan New York area.

Specialty Contractors segment revenues increased by $689.6 million, from $112.9 million in 2010 to $802.5 million in 2011, primarily due to the recent acquisitions which contributed approximately $767.9 million in revenues in the aggregate.

Management Services segment revenues increased by $7.4 million (or 3.8%), from $195.7 million in 2010 to $203.1 million in 2011, primarily due to the start-up of a task order contract for containerized housing in southern Iraq offset by the substantial completion of U.S. military facilities in Iraq.

Income from Construction Operations		168.4			172.3			(3.9	)		(2.3	)%

*NM – Not Meaningful

Building segment income from construction operations decreased by $42.9 million (or 48.1%), from $89.2 million in 2010 to $46.3 million in 2011, primarily due to a decline in volume and operating margin caused by the substantial completion of successful large public works projects in Las Vegas and Philadelphia.

Civil segment income from construction operations decreased by $9.5 million (or 10.8%), from $88.1 million in 2010 to $78.6 million in 2011, primarily due to a decline in operating margin caused by the substantial completion and favorable performance on several projects in the metropolitan New York area and the timing of production on other large civil projects currently in backlog. This decrease was partly offset by the recent acquisitions which contributed approximately $27.5 million in income from construction operations (net of intangible assets amortization) in the aggregate.

Specialty Contractors segment income from construction operations increased by $59.3 million, from $6.3 million in 2010 to $65.6 million in 2011, primarily due to the recent acquisitions which contributed approximately $71.9 million in income from construction operations (net of intangible assets amortization) in the aggregate.

Management Services segment income from construction operations increased by $0.1 million (or 0.5%), from $22.2 million in 2010 to $22.3 million in 2011, primarily due to the changes in volume of revenues discussed above.

Corporate G&A expense increased by $10.9 million (or 32.5%) from $33.5 million in 2010 to $44.4 million in 2011 primarily due to a change in our methodology of allocating corporate expenses to our segments, as well as additional acquisition-related expenses incurred in 2011.

*NM – Not Meaningful

Other income (expense), net increased by $6.7 million, from expense of $2.3 million in 2010 to income of $4.4 million in 2011, primarily due to the net reduction in certain business acquisition related liabilities of $7.3 million as compared to a $3.3 million net reduction in certain business acquisition related liabilities in 2010.

Table of Contents

Interest expense increased by $25.2 million (or 237.7%), from $10.6 million in 2010 to $35.8 million in 2011, primarily due to interest recorded on our $300 million senior unsecured notes, which were issued in October 2010, our $200 million term loan, and on borrowings under our revolving facility.

The Provision for Income Taxes decreased by $5.1 million (or 9.1%), from $56.0 million in 2010 to $50.9 million in 2011, due to the decrease in pretax income. The increase in the effective tax rate from 35.1% in 2010 to 37.1% in 2011 was primarily due to a more favorable return to provision adjustment experienced in 2010 versus 2011.

Potential Impact of Current Economic Conditions

Current economic and financial market conditions in the United States and overseas, including severe disruptions in the credit markets, have had an adverse effect on our results of operations. If there is a prolonged economic recession or depression or if government efforts to stabilize and revitalize credit markets and financial institutions are not effective, current economic and financial market conditions could continue to adversely affect our results of operations in future periods. The current instability in the financial markets has made it difficult for certain of our customers, including state and local governments, to access the credit markets to obtain financing or refinancing, as the case may be, to fund new construction projects on satisfactory terms or at all. State and local governments also are facing significant budget shortfalls as a result of declining tax and other revenues, which may cause them to defer or cancel planned infrastructure projects. We may encounter increased levels of deferrals and delays related to new construction projects in the future. Difficulty in obtaining adequate financing due to the unprecedented disruption in the credit markets may increase the rate at which our customers defer, delay or cancel proposed new construction projects. Such deferrals, delays or cancellations could have an adverse impact on our future operating results.

Liquidity and Capital Resources

Cash and Working Capital

Cash and cash equivalents consist of amounts held by us as well as our proportionate share of amounts held by construction joint ventures. Cash held by us is available for general corporate purposes, while cash held by construction joint ventures is available only for joint venture-related uses. Joint venture cash and cash equivalents are not restricted to specific uses within those entities; however, the terms of the joint venture agreements limit our ability to distribute those funds and use them for corporate purposes. Cash held by construction joint ventures is distributed from time to time to us and to the other joint venture participants in accordance with our respective percentage interest after the joint venture partners determine that a cash distribution is prudent. Cash distributions received by us from our construction joint ventures are then available for general corporate purposes.

At December 31, 2012 and 2011, cash held by us and available for general corporate purposes was $70.8 million and $109.2 million, respectively, our proportionate share of cash held by joint ventures and available only for joint venture-related uses was $97.3 million and $95.1 million, respectively, and our restricted cash was $38.7 million and $35.4 million, respectively.

We do not believe that it is likely that we will be called upon to contribute significant additional capital in the event of default by any of our joint venture partners. 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 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.

Table of Contents

Billing procedures in the construction industry are based on the specific billing terms of a contract. For example, billings may be based on various measures of performance, such as cubic yards excavated, architect’s estimates of completion, costs incurred on cost-plus type contracts or weighted progress from a cost loaded construction time schedule. Billings are generally on a monthly basis and are reviewed and approved by the customer prior to submission. Therefore, once a bill is submitted, we are generally able to collect amounts owed to us in accordance with the payment terms of the contract. In addition, receivables of a contractor usually include retentions, or amounts that are held back until contracts are completed or until specified contract conditions or guarantees are met. Retentions are governed by contract provisions and are typically a fixed percentage (for example, 5% or 10%) of each billing. We generally follow the policy of paying our vendors and subcontractors after we receive payment from our customer.

A summary of cash flows for each of fiscal years 2012, 2011, and 2010 is set forth below:

	Year Ended December 31,
	2012			2011			2010
	(In millions)
Cash flows provided (used) by:
Operating activities	$	(67.9	)	$	(31.6	)	$	25.5
Investing activities		(16.8	)		(375.3	)		(70.8	)
Financing activities		48.5			139.7			168.4
Net (decrease) increase in cash		(36.2	)		(267.2	)		123.1
Cash at beginning of year		204.2			471.4			348.3
Cash at end of year	$	168.0		$	204.2		$	471.4

During 2012, we used $67.9 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 $16.8 million in cash from investing activities, primarily due to purchase construction equipment, offset by the proceeds from the sales of several of our auction rate securities and construction equipment. We received $48.5 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.

During 2011, we used $31.6 million in cash flow from operating activities. The operating cash used was primarily due to cash payments made for income taxes and interest, offset by collections on several large projects in our Building, Civil and Management Services segments during 2011. We used $375.3 million in cash to fund investing activities, primarily for the acquisitions discussed above as well as cash used to purchase construction equipment. We received $139.7 million in cash from financing activities, primarily due to our $200 million term loan. Our cash balance decreased by $267.2 million primarily due to the use of cash to fund our acquisition strategy during 2011.

During 2010, we generated $25.5 million in cash from operating activities. The cash flow from operating activities is primarily due to operating cash flow from our Civil segment which more than offset operating cash uses from our Building segment resulting from the timing of receivable collections on certain large projects, including receivables on the CityCenter project. We used $70.8 million in cash to fund investing activities, including $30.9 million to fund the acquisition of Superior Gunite; $25.2 million to purchase construction equipment; and $23.6 million for restricted cash to secure insurance-related contingent obligations, such as insurance claim deductibles, in lieu of utilizing letters of credit. We received $168.4 million from financing activities which primarily reflects proceeds of $297.8 million received in conjunction with our issuance of the senior unsecured notes, net of the debt discount. Cash flow used for financing activities also includes $47.1 million for the payment of a special dividend on our common stock; $39.4 million for the repurchase of shares of our common stock in accordance with our previously announced share repurchase program; a net reduction in debt of $29.0 million; and $7.9 million for costs primarily associated with our issuance of the senior unsecured notes.

Table of Contents

At December 31, 2012, we had working capital of $747.6 million, a ratio of current assets to current liabilities of 1.61 to 1.00, and a ratio of debt to equity of 0.64 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 debt to equity of 0.48 to 1.00 at December 31, 2011. Our stockholders’ equity decreased to $1.1 billion as of December 31, 2012, compared to $1.4 billion as of December 31, 2011. The increase in our debt to equity ratio and the decrease in our stockholders’ equity at December 31, 2012 primarily reflect the impact of the $376.6 million goodwill and intangible asset impairment charge ($326.4 million after-tax) recorded in the second quarter of 2012. At December 31, 2012, we were in compliance with the covenants under our credit agreement.

Long-term Investments

At December 31, 2012, we had investments in auction rate securities (“ARS”) of $46.3 million measured 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 credit facility, we do not expect the short-term lack of liquidity of our ARS investments to materially affect our overall liquidity position or our ability to execute our current business plan. During 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 ARS, see Note 1 – Description of Business and Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements in Part IV, Item 15. Exhibits and Financial Statement Schedules.

We hold a variety of interest bearing ARS, the majority of which were rated AA+ at December 31, 2012, that generally represent interests in pools of interest bearing student loans. These ARS provide liquidity via an auction process that resets the applicable interest rate at predetermined intervals, typically every 7 or 28 days. In the event that such auctions are unsuccessful, the holder of the securities is not able to access these funds until a future auction of these investments is successful. An unsuccessful auction results in a lack of liquidity in the securities but does not signify a default by the issuer. Upon an unsuccessful auction, the interest rates do not reset at a market rate but instead reset based upon a formula contained in the security, which rate is generally higher than the current market rate. During the first quarter of 2008, we made substantial additional investments in ARS. Since mid-February 2008, regularly scheduled auctions for these securities started to fail throughout the market at a significant rate. Since that time, we have been successful in liquidating a significant portion of our investment in ARS at par value. During 2011, we determined that the carrying value of our investment in ARS was in excess of its fair value and we recorded an impairment charge of $4.8 million which were deemed to be other-than-temporary, thereby resulting in a charge to income. We did not record any additional impairment charge during the fourth quarter of 2012 since the carrying value of our ARS as of December 31, 2012 approximated fair value.

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.

Debt

Debt was $737.1 million at December 31, 2012, an increase of $64.6 million from $672.5 million at December 31, 2011, primarily due to outstanding borrowings of $120.0 million on our revolving line of credit partially offset by principal payments. The remaining balance of our outstanding debt is generally secured by the underlying assets. Excluding the unsecured senior notes of $298.3 million and our $200 million term loan (which had been paid down to $152.5 million as of December 31, 2012) as discussed below, approximately $140.7 million of the remaining $166.3 million in total debt outstanding at December 31, 2012 carries interest at a fixed rate.

The Company was in compliance with the modified financial covenants of the Amended Credit Agreement for the period ended December 31, 2012.

On August 2, 2012, we entered into an amendment to our Fifth Amended and Restated 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. See Amended Credit Agreement below for a detailed discussion of this amendment. There were no other material changes in our contractual debt obligations as of December 31, 2012.

7.625% Senior Notes due 2018

On October 20, 2010, we completed a private placement offering of $300 million in aggregate principal amount of its 7.625% senior unsecured notes due November 1, 2018 (the “Senior Notes”). The Senior Notes were priced at 99.258%, resulting in a yield to maturity of 7.75%. The Senior Notes were made available in a private offering that is exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”). The private placement of the Senior Notes resulted in proceeds to us of approximately $293.2 million after a debt discount of $2.2 million and initial debt issuance costs of $4.6 million. The Senior Notes were issued pursuant to an indenture (the “Indenture”), dated as of October 20, 2010 by and among us, our subsidiary guarantors and Wilmington Trust FSB, as trustee (the “Trustee”).

The Senior Notes mature on November 1, 2018, and bear interest at a rate of 7.625% per annum, payable semi-annually in cash in arrears on May 1 and November 1 of each year, beginning on May 1, 2011. The Senior Notes are our senior unsecured obligations and are guaranteed by substantially all of our existing and future subsidiaries that guarantee obligations under our Amended Credit Agreement.

The terms of the Indenture, among other things, limit our ability and our restricted subsidiaries to (i) incur additional indebtedness or issue certain preferred stock; (ii) pay dividends on, or make distributions in respect of, our capital stock or repurchase our capital stock; (iii) make certain investments or other restricted payments; (iv) sell certain assets; (v) create liens or use assets as security in other transactions; (vi) merge, consolidate or transfer or dispose of substantially all of our assets; and (vii) engage in certain transactions with affiliates.

The Senior Notes are redeemable, in whole or in part, at any time on or after November 1, 2014, at the redemption prices specified in the Indenture, together with accrued and unpaid interest, if any, to the redemption date. At any time prior to November 1, 2013, we may redeem up to 35% of the aggregate principal amount of the Senior Notes with the net cash proceeds from certain equity offerings at a redemption price equal to 107.625% of the principal amount thereof, together with accrued and unpaid interest, if any, to the redemption date. In addition, at any time prior to November 1, 2014, we may redeem the Senior Notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the Senior Notes so redeemed, plus a “make whole” premium, together with accrued and unpaid interest, if any, to the redemption date.

Upon the occurrence of a change of control triggering event specified in the Indenture, we must offer to purchase the Senior Notes at a redemption price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of purchase.

The Indenture provides for customary events of default (subject in certain cases to customary grace and cure periods), which include nonpayment, breach of covenants in the Indenture, payment defaults or acceleration of other indebtedness, a failure to pay certain judgments and certain events of bankruptcy and insolvency. If an event of default occurs and is continuing, the Trustee or holders of at least 25% in principal amount of the outstanding Senior Notes may declare the principal, accrued and unpaid interest, if any, on all the Senior Notes to be due and payable.

In April 2011, we filed an amended registration statement with the Securities and Exchange Commission with respect to an offer to exchange the Senior Notes for a new issue of debt securities registered under the Securities Act (the “Exchange Offer”), with terms substantially identical to those of the Senior Notes, (except for provisions relating to the transfer restrictions and payment of additional interest), and to keep the Exchange Offer open for at least 30 business days (the “Registration Statement”). The Exchange Offer was consummated in June 2011.

Amended Credit Agreement

On August 3, 2011 we entered into a Fifth Amended and Restated Credit Agreement (the “Credit Agreement”) with Bank of America, N.A., which has been amended by a Joinder Agreement dated October 21, 2011 executed by Becho, Inc. On August 2, 2012, we entered into a First Amendment (the “First Amendment”) to our 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 with 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. The obligations under the First Amendment are secured by a lien on all personal property of the Company and its subsidiaries party thereto.

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-K, we are in compliance and expect to continue to be in compliance with the modified financial covenants under the First Amendment.

The Amended Credit Agreement allows us 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, we have the option to increase the base facility by up to an additional $50 million. Substantially all of our subsidiaries unconditionally guarantee the obligations of the Company under the Amended Credit Agreement. The obligations under the Amended Credit Agreement are secured by a lien on all our personal property and our 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 $152.5 million at December 31, 2012.

We had $120.0 million of outstanding borrowings under the Revolving Facility as of December 31, 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 December 31, 2012 and 2011, respectively. Accordingly, at December 31, 2012, the Company had $179.8 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.

The Company was in compliance with the modified financial covenants of the Amended Credit Agreement for the period ended December 31, 2012.

On August 26, 2011, we 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 Amended Credit Agreement (based upon our 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.

Debt Agreements from Recent Acquisitions

In connection with the acquisition of Frontier-Kemper, we assumed approximately $52 million of debt of which approximately $35 million was paid off upon the closing of the transaction. Substantially all of the debt remaining existed in the form of a promissory note payable from Frontier-Kemper to the former sole shareholder of Frontier-Kemper in the amount of $17.1 million (the “Frontier-Kemper Seller Note”). Interest under the Frontier-Kemper Seller Note accrues at the rate of 2% per annum with all accrued but unpaid interest payable on September 30, 2011 and December 31, 2011. Additionally, the Frontier-Kemper Seller Note contains an indemnification provision allowing us to offset balances against the principal due under certain circumstances. This provision resulted in a reduction in the principal due under the Frontier-Kemper Seller Note to $14.1 million, and this amount plus all accrued interest was paid off on December 30, 2011.

In connection with the GreenStar merger, we issued to the interest holder representative, on behalf of certain of GreenStar’s former equity holders, a promissory note in the amount of approximately $74.9 million (the “GreenStar Seller Note”). Interest under the GreenStar Seller Note accrued at the rate of 8% per annum with all accrued but unpaid interest payable on August 1, September 1 and October 1, 2011. The GreenStar Seller Note and all accrued interest were paid off on August 3, 2011.

In connection with the acquisition of Lunda, we issued to the former Lunda shareholders promissory notes in an aggregate amount of approximately $21.7 million (the “Lunda Seller Notes”). Interest under the Lunda Seller Notes accrues at the rate of 5% per annum with all accrued but unpaid interest payable annually. The Lunda Seller Notes mature on July 1, 2016. We may prepay all or any portion of the Lunda Seller Notes at any time without premium or penalty. To the extent that the Company prepays all or any portion of its outstanding Senior Notes, it is also required to repay a pro rata portion (based upon the amount being prepaid under the Senior Notes and the total amount outstanding under the Senior Notes) of the Lunda Seller Notes. The Lunda Seller Notes are guaranteed by Lunda, which, as a result of the acquisition, is a wholly owned subsidiary of the Company.

Collateralized Loans

During 2011, we entered into several equipment financing arrangements for our existing and our recently acquired equipment fleets as discussed in more detail below. We attempted to take advantage of the opportunity to fix low interest rates for these fleets which has provided us with additional cash flows available for general corporate purposes.

In September 2011, we entered into two new equipment financing agreements. We obtained two loans for $12.5 million each, which are collateralized by construction equipment owned by us. The terms of each of the loans include equal monthly installments inclusive of principal and interest at an interest rate of 2.21% payable over a five-year period. In August 2011, we entered into a new equipment financing agreement. We obtained a loan totaling $25.0 million, which is collateralized by construction equipment owned by us. The terms of the loan include equal monthly installments inclusive of principal and interest at an interest rate of 2.53% payable over a five-year period. In March 2011, we paid off and subsequently refinanced several of our equipment financing agreements at lower interest rates and also entered into several new equipment financing agreements. The refinancing resulted in payments totaling $27.4 million which paid off the previous agreements in place. We obtained loans totaling $59.7 million, which are collateralized by construction equipment owned by us. The terms of the loans include equal monthly installments inclusive of principal and interest at an interest rate of 3.98% payable over a five-year period, with balloon payments totaling $8.8 million in 2016.

Stockholders' Equity

Our book value per common share was $24.05 at December 31, 2012, compared to $29.58 at December 31, 2011, and $27.88 at December 31, 2010. The major factors impacting stockholders’ equity during the three year period were the net income (loss) recorded in all three years; the annual amortization of stock compensation expense; common stock options exercised; the excess income tax benefit attributable to stock-based compensation; the repurchase of our common stock in 2010 in conjunction with our share repurchase program; and the declaration of a special dividend on our common stock in 2010. Also, we were required to adjust our accrued pension liability by an increase of $1.7 million in 2012, an increase of $14.8 million in 2011, and an increase of $4.9 million in 2010, respectively, and a cumulative increase of $39.5 million in prior years, with the offset to accumulated other comprehensive income (loss) which resulted in an aggregate $60.9 million pretax accumulated other comprehensive loss reduction in stockholders’ equity at December 31, 2012 (see Note 8 – Employee Benefit Plans of the Notes to Consolidated Financial Statements in Part IV, Item 15. Exhibits and Financial Statement Schedules). Adjustments to the amount of this accrued pension liability will be recorded in future years based upon periodic re-evaluation of the funded status of our pension plans.

Related Party Transactions

We are subject to certain related party transactions with our Chairman and Chief Executive Officer, Ronald N. Tutor, and Raymond R. Oneglia, the Vice Chairman of O&G Industries, Inc., one of our directors. A more detailed description of these transactions will be set forth in the sections entitled “Certain Relationships and Related Party Transactions” in the definitive proxy statement in connection with our 2013 Annual Meeting of Stockholders (the “Proxy Statement”), which section is incorporated herein by reference.

New Accounting Pronouncements

During the year ended December 31, 2012, we adopted the following accounting pronouncements that were issued by the Financial Accounting Standards Board (“FASB”) in 2011:

In May 2011, the 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.

Table of Contents

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.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our exposure to market risk for changes in interest rates primarily relates to borrowings under our Amended Credit Agreement, our Term Loan, and our short-term and long-term investment portfolios. Our Revolving Facility is available for us to borrow, when needed, for general corporate purposes, including working capital requirements and capital expenditures. Borrowings under our Revolving Facility and outstanding principal on our Term Loan bear interest at the applicable LIBOR or base rate, as defined, and therefore we are subject to fluctuations in interest rates. We borrowed from our Revolving Facility during a brief period in 2011; however, these borrowings were paid off as of December 31, 2011. Additionally in August 2011, we entered into the Swap Agreement with Bank of America, N.A. to establish a long-term interest rate for the Term Loan. The Swap Agreement will become effective for 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 Amended Credit Agreement (based upon the Company’s consolidated leverage ratio) plus 97.5 basis points. Of our remaining outstanding debt at December 31, 2012 (excluding the Term Loan balance of $152.5 million, the revolving line of credit of $120.0 million and the Senior Notes balance of $298.3 million), totaling $166.3 million, approximately $140.7 million carries interest at a fixed rate. Accordingly, we do not believe our liquidity or our operations are subject to significant market risk for changes in interest rates.

We hold a variety of interest bearing auction rate securities, the majority of which were rated AA+ at December 31, 2012, that generally represent interests in pools of interest bearing student loans. These auction rate securities provide liquidity via an auction process that resets the applicable interest rate at predetermined intervals, typically every 7 or 28 days. In the event that such auctions are unsuccessful, the holder of the securities is not able to access these funds until a future auction of these investments is successful. An unsuccessful auction results in a lack of liquidity in the securities but does not signify a default by the issuer. Upon an unsuccessful auction, the interest rates do not reset at a market rate but instead reset based upon a formula contained in the security, which rate is generally higher than the current market rate. Since mid-February 2008, regularly scheduled auctions for these securities started to fail throughout the market at a significant rate. Since that time, we have been successful in liquidating at par value a significant portion of our investment in auction rate securities. At December 31, 2012, we had investments in auction rate securities of $46.3 million which are reflected at fair value after cumulative net fair value adjustments of $1.0 million. These investments are considered to be “available-for-sale” and are classified as long-term investments. 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 auction rate securities. Based on our ability to access our cash equivalent investments, and our available Revolving Facility, we do not expect the short-term lack of liquidity to affect our overall liquidity position or our ability to execute our current business plan.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures – As required by Rule 13a-15(e) under the Securities Exchange Act of 1934, the Company, with the participation of our Chief Executive Officer and Chief Financial Officer, has carried out an evaluation, of the effectiveness of the design and operation of our disclosure controls and procedures as of December 31, 2012. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2012, our disclosure controls and procedures were effective, in that they provide reasonable assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act were recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. Our disclosure controls and procedures are designed to ensure that information we are required to disclose in such reports is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures.

Management’s Report On Internal Control Over Financial Reporting - Our management, under the supervision of our Chief Executive Officer and Chief Financial Officer, is responsible for establishing and maintaining an adequate system of internal control over financial reporting as such term is defined in Exchange Act Rules 13a–15(f). In designing and evaluating our system of internal control over financial reporting, we recognize that inherent limitations exist in any control system no matter how well designed and operated, and we can only provide reasonable, not absolute, assurance of achieving the desired control objectives.. In making this assessment, management utilized the criteria issued in Internal Control – Integrated Framework by the Committee of Sponsoring Organizations (COSO) of the Treadway Commission. Based on this assessment, management concluded that, as of December 31, 2012, our internal control over financial reporting was effective based on those criteria.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. In addition, projections of any evaluation of the effectiveness to future periods are subject to the risk that controls may become inadequate due to changes in conditions, or that the degree of compliance with policies and procedures may deteriorate.

Deloitte & Touche, LLP, the independent registered public accounting firm that audited our consolidated financial statements included in this Annual Report on Form 10-K, has issued an attestation report on the Company’s internal control over financial reporting as of December 31, 2012. The report is included below in this Item 9A under the heading “Report of Independent Registered Public Accounting Firm.”

Changes in Internal Control Over Financial Reporting - There were no changes in our internal control over financial reporting for the fiscal quarter ended December 31, 2012 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. We have completed the integration of our 2011 acquisitions into our internal control framework that resulted in no further changes in our assessment.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Tutor Perini Corporation

Sylmar, California

We have audited the internal control over financial reporting of Tutor Perini Corporation and subsidiaries (the "Company") as of December 31, 2012, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements as of and for the year ended December 31, 2012 of the Company and our report dated February 22, 2013 expressed an unqualified opinion on those financial statements.

[1] Description of Business and Summary of Significant Accounting Policies

(a) Nature of Business

Tutor Perini Corporation, formerly known as Perini Corporation, was incorporated in 1918 as a successor to businesses which had been engaged in providing construction services since 1894. Tutor Perini Corporation and its wholly owned subsidiaries (the “Company”) provide diversified general contracting, construction management and design-build services to private customers and public agencies throughout the world. The Company’s construction business is conducted through four basic segments or operations: Building, Civil, Specialty Contractors and Management Services. The 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. The 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. The 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. The 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 Company offers general contracting, pre-construction planning and comprehensive project management services, including planning and scheduling of 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. The Company also offers self-performed construction services, including site work, concrete forming and placement, steel erection, electrical and mechanical, plumbing and HVAC. The Company provides these services by using traditional general contracting arrangements, such as fixed price, guaranteed maximum price and cost plus fee contracts and construction management or design-build contracting arrangements.

In an effort to leverage the Company’s expertise and limit its financial and/or operational risk on certain large or complex projects, the Company participates in construction joint ventures, often as the sponsor or manager of the project, for the purpose of bidding and, if awarded, providing the agreed upon construction services. Each participant usually agrees in advance to provide a predetermined percentage of capital, as required, and to share in the same percentage of profit or loss of the project.

(b) Basis of Presentation

The accompanying consolidated financial statements have been prepared in compliance with accounting principles accepted in the United States (“U.S. GAAP”) as codified in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification.

Prior to 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 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 years ended December 31, 2011 and 2010, this correction resulted in a decrease in cash flows provided by operating activities of $1.1 million and $0.7 million, an increase in cash flows provided by investing activities of $3.0 million and $6.7 million, and a decrease in cash flows provided by financing activities of $1.9 million and $6.0 million, respectively, in the Consolidated Statements of Cash Flows. There was no impact on the Company’s Consolidated Statements of Operations or Balance Sheets.

The consolidated financial statements include the accounts of Tutor Perini Corporation and its wholly owned subsidiaries. The Company’s interests in construction joint ventures are accounted for using the proportionate consolidation method whereby the Company’s proportionate share of each joint venture’s assets, liabilities, revenues and cost of operations are included in the appropriate classifications in the consolidated financial statements. All intercompany transactions and balances have been eliminated in consolidation.

(d) Use of and Changes in Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company’s construction business involves making significant estimates and assumptions in the normal course of business relating to its contracts and its joint venture contracts due to, among other things, the one-of-a-kind nature of most of its projects, the long-term duration of its contract cycle and the type of contract utilized. The most significant estimates with regard to these financial statements relate to the estimating of total forecasted construction contract revenues, costs and profits in accordance with accounting for long-term contracts and estimating potential liabilities in conjunction with certain contingencies, including the outcome of pending or future litigation, arbitration or other dispute resolution proceedings relating to contract claims. Actual results could differ from these estimates and such differences could be material.

The Company’s estimates of contract revenue and cost are highly detailed. The Company believes that, based on its experience, its current systems of management and accounting controls allow it to produce materially reliable estimates of total contract revenue and cost during any accounting period. However, many factors can and do change during a contract performance period which can result in a change to contract profitability from one financial reporting period to another. Some of the factors that can change the estimate of total contract revenue and cost include differing site conditions (to the extent that contract remedies are unavailable), the availability of skilled contract labor, the performance of major material suppliers to deliver on time, the performance of major subcontractors, unusual weather conditions and the accuracy of the original bid estimate. Because the Company has many contracts in process at any given time, these changes in estimates can offset each other minimizing the impact on overall profitability. However, large changes in cost estimates on larger, more complex construction projects can have a material impact on the Company’s financial statements and are reflected in results of operations when they become known.

Management focuses on evaluating the performance of contracts individually. 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 its 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 year ended December 31, 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. Excluding the discrete items that impacted the Company’s effective tax rate, this change in estimate resulted in a $12.4 million increase in income from construction operations, a $7.5 million increase in net income and a $0.16 increase in diluted earnings per common share during 2012.

Contracts vary in lengths and larger contracts can span over three to four years. At various stages of a contract’s lifecycle, different types of changes in estimates are more typical. Generally during the early ramp up stage, cost estimates relating to purchases of materials and subcontractors are frequently subject to revisions. As a contract moves into the most productive phase of execution, change orders, project cost estimate revisions and claims are frequently the sources for changes in estimates. During the contract’s final phase, remaining estimated costs to complete or provisions for claims will be closed out and adjusted based on actual costs incurred. The impact on operating margin in a reporting period and future periods from a change in estimate will depend on the stage of contract completion. Generally, if the contract is at an early stage of completion, the current period impact is smaller than if the same change in estimate is made to the contract at a later stage of completion. Likewise, if the company’s overall project portfolio was to be at a later stage of completion during the reporting period, the overall gross margin could be subject to greater variability from changes in estimates.

[1] Description of Business and Summary of Significant Accounting Policies (continued)

When recording revenue on contracts relating to unapproved change orders and claims, the Company includes in revenue an amount less than or equal to the amount of costs incurred by it to date for contract price adjustments that it seeks to collect from customers for delays, errors in specifications or designs, change orders in dispute or unapproved as to scope or price, or other unanticipated additional costs, in each case when recovery of the costs is considered probable. The amount of unapproved change orders and claim revenues is included in Consolidated Balance Sheets as part of costs and estimated earnings in excess of billings. When determining the likelihood of eventual recovery, the Company considers such factors as evaluation of entitlement, settlements reached to date and our experience with the customer. The settlement of these issues may take years depending upon whether the item can be resolved directly with the customer or involves litigation or arbitration. When new facts become known, an adjustment to the estimated recovery is made and reflected in the current period results.

(e) Method of Accounting for Contracts

Revenues and profits from the Company’s contracts and construction joint venture contracts are recognized by applying percentages of completion for the period to the total estimated revenues for the respective contracts. Percentage of completion is determined by relating the actual cost of the work performed to date to the current estimated total cost of the respective contracts. However, on construction management contracts, profit is generally recognized in accordance with the contract terms, usually on the as-billed method, which is generally consistent with the level of effort incurred over the contract period. When the estimate on a contract indicates a loss, the Company's policy is to record the entire loss during the accounting period in which it is estimable. In the ordinary course of business, at a minimum on a quarterly basis, the Company updates estimates projected total contract revenue, cost and profit or loss for each contract based on changes in facts, such as an approved scope change, and changes in estimates. The cumulative effect of revisions in estimates of the total forecasted revenue and costs, including unapproved change orders and claims, during the course of the work is reflected in the accounting period in which the facts that caused the revision become known. The financial impact of these revisions to any one contract is a function of both the amount of the revision and the percentage of completion of the contract. Amounts up to the costs incurred which are attributable to unapproved change orders and claims are included in the total estimated revenue when realization is probable. Profit from unapproved change orders and claims is recorded in the period such amounts are resolved.

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. Billings in excess of costs and estimated earnings represents the excess of contract billings to date over the amount of contract costs and profits (or contract revenue) recognized to date on the percentage of completion accounting method on certain contracts. Costs and estimated earnings in excess of billings represents the excess of contract costs and profits (or contract revenue) recognized to date on the percentage of completion accounting method over the amount of contract billings to date on the remaining contracts. Costs and estimated earnings in excess of billings results when (1) the appropriate contract revenue amount has been recognized in accordance with the percentage of completion accounting method, but a portion of the revenue recorded cannot be billed currently due to the billing terms defined in the contract and/or (2) costs, recorded at estimated realizable value, related to unapproved change orders or claims are incurred.

For unapproved change orders or claims that cannot be resolved in accordance with the normal change order process as defined in the contract, the Company employs other dispute resolution methods, including mediation, binding and non-binding arbitration, or litigation.

For the Years Ended December 31, 2012, 2011 and 2010

[1] Description of Business and Summary of Significant Accounting Policies (continued)

Costs and estimated earnings in excess of billings related to the Company’s contracts and joint venture contracts consisted of the following:

	At December 31,
	2012		2011
	(in thousands)
Unbilled costs and profits incurred to date*	$	157,119	$	107,645
Unapproved change orders		141,596		136,704
Claims		166,287		114,049
	$	465,002	$	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 December 31, 2012 and December 31, 2011, approximately $62.0 million and $85.2 million, respectively, are amounts subject to pending litigation or dispute resolution proceedings as described in Note 9 – 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 prerequisite for billing “Unbilled costs and profits incurred to date” is provided in the defined billing terms of each of the applicable contracts. The prerequisite for billing “Unapproved change orders” or “Claims” is the final resolution and agreement between the parties. The amount of costs and estimated earnings in excess of billings at December 31, 2012 estimated by management to be collected beyond one year is approximately $181.3 million.

(f) Property and Equipment

Land, buildings and improvements, construction and computer-related equipment and other equipment are recorded at cost. Major renewals and betterments are capitalized and maintenance and repairs are charged to operations as incurred. Depreciation is primarily calculated using the straight-line method for all classifications of depreciable property. Construction equipment is depreciated over estimated useful lives ranging from five to twenty years after an allowance for salvage. The remaining depreciable property is depreciated over estimated useful lives ranging from three to forty years after an allowance for salvage.

(g) Long-Lived Assets

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Recoverability is evaluated by comparing the carrying value of the assets to the undiscounted associated cash flows. When this comparison indicates that the carrying value of the asset is greater than the undiscounted cash flows, a loss is recognized for the difference between the carrying value and estimated fair value. Fair value is determined based either on market quotes or appropriate valuation techniques.

(h) Goodwill and Intangible Assets

Intangible assets with finite lives are amortized over their useful lives. Construction contract backlog is amortized on a weighted average basis over the corresponding contract period. Customer relationships and certain trade names are amortized on a straight-line basis over their estimated useful lives. Goodwill and intangible assets with indefinite lives are not amortized. The Company evaluates intangible assets that are not being amortized at the end of each reporting period to determine whether events and circumstances continue to support an indefinite useful life.

[1] Description of Business and Summary of Significant Accounting Policies (continued)

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 tested for impairment whenever events or circumstances indicate that the carrying value may not be recoverable. The first step in the two-step process of the impairment analysis is 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 exceeds its fair value, a second step must be followed to calculate the goodwill impairment. The second step involves 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 utilizes both an income-based valuation approach as well as a market-based valuation approach. The income-based valuation approach is based on the cash flows that the reporting unit expects to generate in the future and it requires 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 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 utilizes industry multiples of revenues and operating earnings. The Company equally weights 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 is compared to its market capitalization at the valuation date in order to determine an implied control premium. In evaluating whether the Company’s implied control premium is reasonable, the Company considers a number of factors including the following factors of greatest significance.

Market control premium: The Company compares its implied control premium to the average control premium paid in transactions of companies in the construction industry during the year of evaluation.

Sensitivity analysis: The Company performs a sensitivity analysis to determine the minimum control premium required to recover the book value of the Company at the testing date. The minimum control premium required is then compared to the average control premium paid in transactions of companies in the construction industry during the year of evaluation.

Impact of low public float and limited trading activity: A significant portion of the Company’s common stock is owned by the Company’s Chairman and CEO. As a result, the public float of the Company’s common stock, calculated as the percentage of shares of common stock freely traded by public investors divided by the Company’s total shares outstanding, is significantly lower than that of its publicly traded peers. This circumstance does not impact the fair value of the Company, however based on its evaluation of third party market data, the Company believes it does lead to an inherent marketability discount impacting its stock price.

Impairment assessment inherently involves management judgments as to the assumptions used for projections and to evaluate the impact of market conditions on those assumptions. The key assumptions that the Company uses to estimate the fair value of its reporting units under the income-based approach are 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 are developed via the capital asset pricing model which is primarily based upon market inputs. The Company uses discount rates that management feels are an accurate reflection of the risks associated with the forecasted cash flows of its respective reporting units.

To develop the cash flows generated from new work awards and future operating margins, the Company primarily tracks prospective work for each of its reporting units 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 gives consideration to its relationships with the prospective owners, the pool of competitors that are 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 gives consideration to its historical reporting unit operating margins in the end markets that the prospective work opportunities are most significant, current market trends in recent new work procurement, and changes in business strategy.

The Company also estimates 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 the Company tracks:

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.

On a quarterly basis the Company considers whether events or changes in circumstances indicate that assets, including goodwill and intangible assets not subject to amortization might be impaired. In conjunction with this analysis, the Company evaluates whether its current market capitalization is less than its stockholders’ equity and specifically considers (1) changes in macroeconomic conditions, (2) changes in general economic conditions in the construction industry including any declines in market-dependent multiples, (3) cost factors such as increases in raw materials, labor, or other costs that have a negative effect on earnings and cash flows analyses, (4) a reconciliation of the implied control premium to a current market control premium, (5) target price assessments by third party analysts and (6) the impact of current market conditions on its forecast of future cash flows including consideration of specific projects in backlog, pending awards, or large prospect opportunities. The Company also evaluates its most recent assessment of the fair value for each of its reporting units, considering whether its current forecast of future cash flows is in line with those used in its annual impairment assessment and whether there are any significant changes in trends or any other material assumptions used.

The Company has concluded that, as of December 31, 2012, there were no adjustments required to be made to the impairment charges recorded in the second quarter of 2012. See Note 4 – Goodwill and Other Intangible Assets for additional discussion about the interim goodwill and indefinite lived intangible asset impairment test as of June 30, 2012.

(i) Income Taxes

Deferred income tax assets and liabilities are recognized for the effects of temporary differences between the financial statement carrying amounts and the income tax basis of assets and liabilities using tax rates expected to be in effect when such differences reverse. In addition, future tax benefits, such as non-deductible accrued expenses, are recognized to the extent such benefits are more likely than not to be realized as an economic benefit in the form of a reduction of income taxes in future years. The Company recognizes interest and penalties related to uncertain tax positions as a component of the income tax provision.

(j) Earnings (Loss) Per Common Share

Basic earnings (loss) per common share is computed by dividing net income (loss) by the weighted average number of common shares outstanding. Diluted earnings (loss) per common share is similarly computed after giving consideration to the dilutive effect of outstanding stock option shares and outstanding restricted stock units on the weighted average number of common shares outstanding.

The computation of diluted earnings (loss) per common share excludes 1,315,465 stock option shares and 1,291,665 restricted stock units during 2012, 880,000 stock option shares during 2011, and 435,000 stock option shares during 2010 because these shares would have an antidilutive effect.

(k) Cash and Cash Equivalents and Restricted Cash

Cash equivalents include short-term, highly liquid investments with original maturities of three months or less when acquired.

Cash and cash equivalents, as reported in the accompanying Consolidated Balance Sheets, consist of amounts held by the Company that are available for general corporate purposes and the Company’s proportionate share of amounts held by construction joint ventures that are available only for joint venture-related uses, including future distributions to joint venture partners. Restricted cash is primarily held to secure insurance-related contingent obligations, such as insurance claim deductibles, in lieu of letters of credit.

Cash and cash equivalents and restricted cash consisted of the following:

	At December 31,
	2012		2011
	(in thousands)

Corporate cash and cash equivalents (available for general corporate purposes)	$	70,780	$	109,180

Company's share of joint venture cash and cash equivalents (available only for joint venture purposes, including future distributions)		97,276		95,060
	$	168,056	$	204,240
Restricted Cash	$	38,717	$	35,437

[1] Description of Business and Summary of Significant Accounting Policies (continued)

(l) Long-term Investments

The Company’s investment in auction rate securities (“ARS”) is classified as available-for-sale securities based on the Company’s intentions. ARS are recorded at cost with unrealized gains and temporary unrealized losses recorded in accumulated other comprehensive income (loss), net of applicable taxes. Upon realization, those amounts are reclassified from accumulated other comprehensive income (loss) to other income, net. Unrealized losses that are other than temporary and due to a decline in expected cash flows are charged against income.

The Company performs a fair market value assessment of its 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.

(m) Stock-Based Compensation

The Company’s long-term incentive plan allows it 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.

Restricted stock awards and 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. For stock awards that vest subject to the satisfaction of service requirements, compensation expense is measured based on the fair value of the award on the date of grant and is recognized as expense on a straight-line basis (net of estimated forfeitures) over the requisite service period. For stock awards which have a performance component, compensation cost is measured based on the fair value on the grant date (the date performance targets are established) and is recognized on a straight-line basis (net of estimated forfeitures) over the applicable requisite service period as achievement of the performance objective becomes probable.

(n) Insurance Liabilities

The Company typically utilizes third party insurance coverage subject to varying deductible or self-insurance levels with aggregate caps on losses retained. The Company assumes the risk for the amount of the self-insured deductible portion of the losses and liabilities primarily associated with workers' compensation and general liability coverage. In addition, on certain projects, the Company assumes the risk for the amount of the self-insured deductible portion of losses that arise from any subcontractor defaults. Losses are accrued based upon the Company's estimates of the aggregate liability for claims incurred using historical experience and certain actuarial assumptions followed in the insurance industry. The estimate of insurance liability within the self-insured deductible limits includes an estimate of incurred but not reported claims based on data compiled from historical experience.

(o) Fair Value of Financial Instruments

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 and other amounts arising out of normal contract activities, including retentions, which may be settled beyond one year, are estimated to approximate fair values. See Note 3 – Fair Value Measurements for disclosure of the fair value of investments, long-term debt and contingent consideration associated with our acquisitions in 2011.

(p) Foreign Currency Translation

The functional currency for the Company’s foreign subsidiaries is the local currency. Accordingly, the assets and liabilities of those operations are translated into U.S. dollars using current exchange rates at the balance sheet date and operating statement items are translated at average exchange rates prevailing during the period. The resulting cumulative translation adjustment is recorded in the foreign currency translation adjustment account as part of accumulated other comprehensive income (loss) in stockholders’ equity. Foreign currency transaction gains and losses, if any, are included in operations as they occur.

(q) New Accounting Pronouncements

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.

[3] 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 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 values of the fixed rate senior unsecured notes as of December 31, 2012 and 2011 were $309.8 million and $280.5 million, respectively, compared to the carrying values of $298.3 million and $298.0 million, respectively. The fair value of the senior unsecured notes was estimated using Level 1 inputs based on market quotations including broker quotes or interest rates for the same or similar financial instruments at December 31, 2012 and 2011. For other fixed rate debt, fair value is determined using Level 3 inputs based on discounted cash flows for the debt at the Company’s current incremental borrowing rate for similar types of debt. The estimated fair values of other fixed rate debt at December 31, 2012 and 2011 were $145.4 million and $167.7 million, respectively, compared to the carrying amounts of $140.7 million and $162.3 million, respectively. The fair value of variable rate debt, which includes the Term Loan, approximated its carrying value of $298.1 million and $212.2 million at December 31, 2012 and 2011, respectively. See Note 5 – Financial Commitments for a discussion of the Term Loan.

[3] Fair Value Measurements (continued)

(1)

Cash, cash equivalents and restricted cash primarily consist 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 the municipal bonds 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)

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

(4)

At December 31, 2012 and 2011 the Company had $46.3 million and $62.3 million, respectively, 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 December 31, 2012 and 2011 are in securities collateralized by student loan portfolios. At December 31, 2012 and 2011, most of the Company’s ARS were rated AA+ and AAA, respectively. 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.

(5)

As discussed in Note 5 – 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 December 31, 2012 and 2011 above represent the contingent consideration for the Company’s acquisitions in 2011 for which the measurement period for purchase price analysis has concluded.

The Company did not have any transfers between Levels 1 and 2 of financial assets or liabilities that are fair valued on a recurring basis during the years ended December 31, 2012 and 2011.

Balance at December 31, 2011	$	62,311

At December 31, 2012 and 2011, the Company had $46.3 million and $62.3 million, respectively, invested in ARS classified as available-for-sale. All of the ARS as of December 31, 2012, and the majority held at December 31, 2011 totaling $54.3 million, are securities collateralized by student loan portfolios guaranteed by the United States government. Additional amounts totaling $8.0 million at December 31, 2011 were invested in securities collateralized by student loan portfolios which are privately insured. At December 31, 2012 and 2011, most of the Company’s ARS were rated AA+ and AAA, respectively. The Company has classified its ARS investment as long-term as the Company believes the market for government-backed student loans may take in excess of twelve months to recover.

During the twelve months ended December 31, 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 realized loss included in other income (expense), net of $2.7 million. During the twelve months ended December 31, 2011, two of the Company’s ARS were redeemed at full par value. The redemption of the two securities resulted in a pre-tax gain of $0.1 million.

The fair values of the contingent consideration were estimated based on 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%).

(1) During the third quarter of 2011, the Company completed a reorganization which resulted in the formation of the Specialty Contractors reporting unit and reportable segment. The Specialty Contractors reporting unit consists of the following subsidiary companies: WDF, FSE, Nagelbush, Fisk, Desert Mechanical, Inc. (“DMI”) (all previously included in the Building reporting unit), and Superior Gunite (previously included in the Civil reporting unit). The reorganization enabled the Company to focus on vertical integration through increased self-performed work capabilities, while maintaining the specialty contractors business with third parties, and strengthened the Company’s position as a full-service contractor with greater control over scheduled delivery and risk management. The Company reallocated goodwill between its reorganized reporting units based on a relative fair value assessment in accordance with the guidance on segment reporting.

The net change in the carrying amount of goodwill for the year ended December 31, 2012 was primarily due to a goodwill impairment charge of $321.1 million recorded in the second quarter of 2012. See “Goodwill Impairment” below. Since the interim goodwill impairment test as of June 30, 2012, the Company’s annual impairment test, performed in the fourth quarter of 2012, did not indicate any further adjustment to goodwill. No events or circumstances have occurred since June 30, 2012 that would indicate any additional impairment adjustment of goodwill. At December 31, 2012, the fair value of the Management Services reporting unit exceeded its carrying value by 4.5%, while the fair values of the Building, Civil and Specialty Contractors reporting units exceeded their carrying values by more than 10%.

Goodwill Impairment

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 primarily based 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 customer 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.

[4] Goodwill and Other Intangible Assets (continued)

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.

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.

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.

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.

[4] Goodwill and Other Intangible Assets (continued)

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).

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.

7.625% Senior Notes due 2018

On October 20, 2010, the Company completed a private placement offering of $300 million in aggregate principal amount of its 7.625% senior unsecured notes due November 1, 2018 (the “Senior Notes”). The Senior Notes were priced at 99.258%, resulting in a yield to maturity of 7.75%. The Senior Notes were made available in a private offering that is exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”). The private placement of the Senior Notes resulted in proceeds to the Company of approximately $293.2 million after a debt discount of $2.2 million and initial debt issuance costs of $4.6 million. The Senior Notes were issued pursuant to an indenture (the “Indenture”), dated as of October 20, 2010 by and among the Company, its subsidiary guarantors and Wilmington Trust FSB, as trustee (the “Trustee”).

The Senior Notes mature on November 1, 2018, and bear interest at a rate of 7.625% per annum, payable semi-annually in cash in arrears on May 1 and November 1 of each year, beginning on May 1, 2011. The Senior Notes are senior unsecured obligations of the Company and are guaranteed by substantially all of the Company’s existing and future subsidiaries that guarantee obligations under the Company’s Amended Credit Agreement.

The terms of the Indenture, among other things, limit the ability of the Company and its restricted subsidiaries to (i) incur additional indebtedness or issue certain preferred stock; (ii) pay dividends on, or make distributions in respect of, the Company’s capital stock or repurchase the Company’s capital stock; (iii) make certain investments or other restricted payments; (iv) sell certain assets; (v) create liens or use assets as security in other transactions; (vi) merge, consolidate or transfer or dispose of substantially all of the Company’s assets; and (vii) engage in certain transactions with affiliates.

The Senior Notes are redeemable, in whole or in part, at any time on or after November 1, 2014, at the redemption prices specified in the Indenture, together with accrued and unpaid interest, if any, to the redemption date. At any time prior to November 1, 2013, the Company may redeem up to 35% of the aggregate principal amount of the Senior Notes with the net cash proceeds from certain equity offerings at a redemption price equal to 107.625% of the principal amount thereof, together with accrued and unpaid interest, if any, to the redemption date. In addition, at any time prior to November 1, 2014, the Company may redeem the Senior Notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the Senior Notes so redeemed, plus a “make whole” premium, together with accrued and unpaid interest, if any, to the redemption date.

Upon the occurrence of a change of control triggering event specified in the Indenture, the Company must offer to purchase the Senior Notes at a redemption price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of purchase.

In April 2011, the Company filed an amended registration statement with the Securities and Exchange Commission with respect to an offer to exchange the Senior Notes for a new issue of debt securities registered under the Securities Act (the “Exchange Offer”), with terms substantially identical to those of the Senior Notes, (except for provisions relating to the transfer restrictions and payment of additional interest), and to keep the Exchange Offer open for at least 30 business days (the “Registration Statement”). The Exchange Offer was consummated in June 2011.

Amended Credit Agreement

On August 3, 2011 the Company entered into a Fifth Amended and Restated Credit Agreement (the “Credit Agreement”) with Bank of America, N.A., which has been amended by a Joinder Agreement dated October 21, 2011 executed by Becho, Inc. The Credit Agreement allows the Company to borrow up to $300 million on a revolving credit basis (the “Revolving Facility”), with a $50 million sublimit for letters of credit, and an additional $200 million term loan (the “Term Loan”).

On August 2, 2012, the Company entered into a First Amendment (the “First Amendment”) to its Fifth Amended and Restated Credit Agreement (the “Amended Credit Agreement”) 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 Amended Credit Agreement beginning with 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 Company was in compliance with the modified financial covenants of the Amended Credit Agreement for the period ended December 31, 2012.

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 Amended Credit Agreement increases the sublimit for letters of credit from $50 million to $150 million. Substantially all of the Company’s subsidiaries unconditionally guarantee the obligations of the Company under the Amended Credit Agreement. The obligations under the Amended 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 $152.5 million at December 31, 2012.

The Amended Credit Agreement also includes certain customary provisions for this type of facility, including operational covenants restricting liens, investments, indebtedness, fundamental changes in corporate organization, and dispositions of property, and events of default, certain of which include corresponding grace periods and notice requirements.

The Amended Credit Agreement provides for customary events of default with corresponding grace periods, including (i) failure to pay any principal or interest when due, (ii) failure to comply with covenants, (iii) any material representation or warranty made by the Company proving to be incorrect in any material respect, (iv) defaults relating to or acceleration of other material indebtedness, (v) certain insolvency or receivership events affecting the Company, (vi) a change in control of the Company, or (vii) the Company becoming subject to certain material judgments.

In the event of a default, the Administrative Agent, at the request of the requisite number of lenders, must terminate the lenders’ commitments to make loans under the Amended Credit Agreement and declare all obligations under the Amended Credit Agreement immediately due and payable. For certain events of default related to insolvency and receivership, the commitments of the lenders will be automatically terminated and all outstanding obligations of the Company under the Amended Credit Agreement will become immediately due and payable.

The Company had $120.0 million of outstanding borrowings under the Revolving Facility as of December 31, 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 December 31, 2012 and 2011, respectively. Accordingly, at December 31, 2012, the Company had $179.8 million available to borrow under the Amended 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 Amended 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.

Debt Agreements from Recent Acquisitions

In connection with the acquisition of Frontier-Kemper, the Company assumed approximately $52 million of debt of which approximately $35 million was paid off upon the closing of the transaction. Substantially all of the debt remaining existed in the form of a promissory note payable from Frontier-Kemper to the former sole shareholder of Frontier-Kemper in the amount of $17.1 million (the “Frontier-Kemper Seller Note”). Interest under the Frontier-Kemper Seller Note accrued at the rate of 2% per annum with all accrued but unpaid interest payable on September 30, 2011. Additionally, the Frontier-Kemper Seller Note contained an indemnification provision allowing the Company to offset balances against the principal due under certain circumstances. This provision resulted in a reduction in the principal due under the Frontier-Kemper Seller Note to $14.1 million, and this amount plus all accrued interest was paid off on December 30, 2011.

In connection with the acquisition of GreenStar, the Company issued to the interest holder representative, on behalf of certain of GreenStar’s former equity holders, a promissory note in the amount of approximately $74.9 million (the “GreenStar Seller Note”). Interest under the GreenStar Seller Note accrued at the rate of 8% per annum with all accrued but unpaid interest payable on August 1, September 1 and October 1, 2011. The GreenStar Seller Note and all accrued interest were paid off on August 3, 2011.

In connection with the acquisition of Lunda, the Company issued to the former Lunda shareholders promissory notes in an aggregate amount of approximately $21.7 million (the “Lunda Seller Notes”). Interest under the Lunda Seller Notes accrues at the rate of 5% per annum with all accrued but unpaid interest payable annually. The Lunda Seller Notes mature on July 1, 2016. The Company may prepay all or any portion of the Lunda Seller Notes at any time without premium or penalty. To the extent that the Company prepays all or any portion of its outstanding Senior Notes, it is also required to repay a pro rata portion (based upon the amount being prepaid under the Senior Notes and the total amount outstanding under the Senior Notes) of the Lunda Seller Notes. The Lunda Seller Notes are guaranteed by Lunda, which, as a result of the acquisition, is a wholly owned subsidiary of the Company.

Collateralized Loans

During 2011, the Company entered into several equipment financing arrangements for its existing and its recently acquired equipment fleets as discussed in more detail below. The Company attempted to take advantage of the opportunity to fix low interest rates for these fleets which has provided additional cash flows available for general corporate purposes.

In September 2011, the Company entered into two new equipment financing agreements. The Company obtained two loans for $12.5 million each, which are collateralized by construction equipment owned by the Company. The terms of each of the loans include equal monthly installments inclusive of principal and interest at an interest rate of 2.21% payable over a five-year period. In August 2011, the Company entered into a new equipment financing agreement. The Company obtained a loan totaling $25.0 million, which is collateralized by construction equipment owned by the Company. The terms of the loan include equal monthly installments inclusive of principal and interest at an interest rate of 2.53% payable over a five-year period. In March 2011, the Company paid off and subsequently refinanced several of its equipment financing agreements at lower interest rates and also entered into several new equipment financing agreements. The refinancing resulted in payments totaling $27.4 million which paid off the previous agreements in place. The Company obtained loans totaling $59.7 million, which are collateralized by construction equipment owned by the Company. The terms of the loans include equal monthly installments inclusive of principal and interest at an interest rate of 3.98% payable over a five-year period, with balloon payments totaling $8.8 million in 2016.

The Company’s provision for income taxes and effective tax rate for the year ended December 31, 2012 were significantly impacted by the goodwill and intangible asset impairment charge discussed in Note 4 – Goodwill and Other Intangible Assets above. Of the total goodwill and intangible asset impairment charge of $376.6 million, approximately $255.0 million pertained to goodwill that had no corresponding tax basis. The tax effect of the impairment charge resulted in a reduction in the Company's provision for income taxes of approximately $50.2 million in 2012.

[6] Income Taxes (continued)

The Company’s 2010 U.S. Federal tax return is currently being audited by the Internal Revenue Service. The Company currently does not expect any material adjustments to arise from this audit.

The net deferred tax liability is classified in the Consolidated Balance Sheets based on when the future benefit (expense) is expected to be realized as follows:

	December 31,
	2012			2011
	(in thousands)
Current deferred tax asset	$	10,071		$	-

Long-term deferred tax liability		(109,900	)		(97,921	)
Net deferred tax liability		(75,993	)		(102,085	)

At December 31, 2012, the Company had a valuation allowance of $2.8 million for federal and state capital loss carryforwards as the ultimate utilization of this item was less than “more likely than not”. The valuation allowance increased in the current year by $2.8 million due to the capital losses realized on the sale of auction rate securities.

In general, it is the practice and intention of the Company to reinvest the earnings of its non-U.S. subsidiaries in those operations. Generally, such amounts become subject to U.S. taxation upon the remittance of dividends and under certain other circumstances. As of December 31, 2012 and 2011, unremitted earnings of foreign subsidiaries, which have been or are intended to be permanently invested, aggregated approximately $14.3 million and $15.3 million, respectively. It is not practicable to estimate the amount of deferred tax liability related to investments in these foreign subsidiaries.

[8] Employee Benefit Plans

Defined Benefit Pension Plan

The Company has a defined benefit pension plan that covers certain of its executive, professional, administrative and clerical employees, subject to certain specified service requirements. The plan is noncontributory and benefits are based on an employee's years of service and "final average earnings", as defined. The plan provides reduced benefits for early retirement and takes into account offsets for social security benefits. The Company also has an unfunded supplemental retirement plan (“Benefit Equalization Plan”) for certain employees whose benefits under the defined benefit pension plan were reduced because of compensation limitations under federal tax laws. Effective June 1, 2004, all benefits accruals under the Company’s pension plan and Benefit Equalization Plan were frozen; however, the current vested benefit was preserved. Pension disclosure as presented below includes aggregated amounts for both of the Company’s plans, except where otherwise indicated.

The Company historically has used the date of its fiscal year-end as its measurement date to determine the funded status of the plan.

A summary of net periodic benefit cost is as follows:

	Year ended December 31,
	2012			2011			2010
	(dollars in thousands)
Interest cost on projected benefit obligation	$	4,011		$	4,526		$	4,531
Return on plan assets		(4,783	)		(5,046	)		(4,960	)
Recognized net actuarial losses		5,487			4,050			2,818
Net periodic benefit cost	$	4,715		$	3,530		$	2,389

Actuarial assumptions used to determine net cost:
Discount rate		4.10	%		5.18	%		5.84	%
Expected return on assets		7.00	%		7.50	%		7.50	%
Rate of increase in compensation	n.a.			n.a.			n.a.

The target asset allocation for the Company’s pension plan by asset category for 2013 and the actual asset allocation at December 31, 2012 and 2011 by asset category are as follows:

	Percentage of Plan Assets at December 31,
	Target
	Allocation
Asset Category	2013			2012			2011
Cash		5.0	%		6.6	%		41.8	%
Equity securities:
Domestic		70.0	%		67.5	%		49.5	%
International		20.0	%		20.8	%		8.7	%
Fixed income securities		5.0	%		5.1	%		0.0	%
Total		100.0	%		100.0	%		100.0	%

During 2012, the Company established a new target asset allocation based on the current economic environment to maximize returns in consideration of the long-term nature of the obligations. The Company purchased fixed income and equity securities of $5.7 million, invested $5.0 million in a global equity partnership fund and increased its net investment in hedge funds by $11.5 million, which resulted in a decreased cash position (35.2%). The Company’s target allocation for 2013 will include 70% domestic equity securities, 20% international equity securities, and 5% fixed income securities.

[8] Employee Benefit Plans (continued)

The net actuarial gain arising during the period, netted against the amortization of the previously existing actuarial loss during the period, resulted in net other comprehensive loss of $1.7 million in 2012, $14.8 million in 2011 and $4.9 million in 2010. Other comprehensive loss attributable to a change in the unfunded projected benefit obligation amounted to a net increase of $39.5 million recognized in prior years. The cumulative net amount of $60.9 million represents the excess of the projected benefit obligations of the Company’s pension plans over the fair value of the plans’ assets as of December 31, 2012, compared to $21.8 million of contributions in excess of the net periodic benefit cost previously recognized. The net amount of $39.2 million is reflected as a liability as of December 31, 2012 with the offset being a reduction in stockholders’ equity. Adjustments to the amount of this pension liability will be recorded in future years, as required, based upon periodic re-evaluation of the funded status of the Company’s pension plans.

The estimated amount of the net accumulated loss that will be amortized from accumulated other comprehensive loss into net period benefit cost in 2013 is $6.3 million.

	Year ended December 31,
	2012			2011
Actuarial assumptions used to determine benefit obligation:
Discount rate		3.58	%		4.10	%
Rate of increase in compensation	n.a.			n.a.
Measurement date	December 31			December 31

The expected long-term rate of return on assets assumption was reduced from 7.00% in 2012 to 6.75% for 2013. The expected long-term rate of return on assets assumption was developed considering forward looking capital market assumptions and historical return expectations for each asset class assuming the Company’s target asset allocation and full availability of invested assets.

Section 401(k) Plans

The Company has several contributory Section 401(k) plans which cover its executive, professional, administrative and clerical employees, subject to certain specified service requirements. The 401(k) expense provision approximated $3.8 million in 2012, $4.2 million in 2011 and $2.4 million in 2010. The Company’s contribution is based on a non-discretionary match of employees’ contributions, as defined.

Cash-Based Compensation Plans

The Company has multiple cash-based compensation plans and a stock-based incentive compensation plan for key employees which are generally based on the Company’s achievement of a certain level of profit. For information on the Company’s stock-based incentive compensation plan, see Note 11 – Stock-Based Compensation.

Multiemployer Plans

The Company also contributes to various multi-employer union retirement plans under collective bargaining agreements which provide retirement benefits for substantially all of its union employees. The Company’s participation in the plans that it considers to be significant for the years ended December 31, 2012 and 2011, is outlined in the tables below. The “EIN/Pension Plan Number” column provides the Employer Identification Number (EIN) and the three-digit plan number, if applicable. Unless otherwise noted, the most recent Pension Protection Act zone status available in 2012 and 2011 is for the plan’s year-end at December 31, 2011, and December 31, 2010, respectively. The zone status is based on information that the Company received from the plan and is certified by the plan’s actuary. Among other factors, plans in the red zone are generally less than 65 percent funded, plans in the yellow zone are less than 80 percent funded, and plans in the green zone are at least 80 percent funded. The “FIP/RP Status Pending/Implemented” column indicates plans for which a financial improvement plan (FIP) or a rehabilitation plan (RP) is either pending or has been implemented. The last column lists the expiration date(s) of the collective-bargaining agreement(s) to which the plans are subject. Finally, the acquisitions of Fisk, Anderson, Frontier-Kemper, WDF, FSE, Nagelbush, Lunda, and Becho during 2011 have increased the number of employees covered by the Company’s multiemployer plans and contributions made. Aside from these acquisitions, there were no other significant changes that affect the comparability of 2010 through 2012 contributions. Under the Employee Retirement Income Security Act, a contributor to a multi-employer plan is liable, only upon termination or withdrawal from a plan, for its proportionate share of a plan’s unfunded vested liability. The Company currently has no intention of withdrawing from any of the multiemployer pension plans in which it participates.

[9] 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 with LAMTA’s opening brief expected in the early part of 2013. 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 appealed the Superior Court decisions and in January 2013, the Superior Court decisions were affirmed in MHDs favor. PKC intends to pursue further appeals. The Appeals Court’s decision becomes effective when the case is transferred back to the Superior Court.

[9] Contingencies and Commitments (continued)

In February 2012, PKC received a $22 million payment for an interest award associated with the Second DRB panel’s awards to PKC. In January 2013, PKC received a $14.8 million payment for backcharges and interest associated with the Fourth DRB panel’s awards to PKC that were confirmed. No trial date has been set in any of the cases or decisions.

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.

[9] Contingencies and Commitments (continued)

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. PTJV is in the process of appealing the ACE decision and exploring a potential mediation with FM.

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 2012 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.

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.

[9] Contingencies and Commitments (continued)

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 December 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. As of December 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 of December 2012, the Company’s mechanic’s lien against the project was $191.3 million.

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. 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.

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 facade 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. In mid-November 2012, the Court granted Chartis’s and Lloyd's respective motions for summary judgment without oral argument. The parties have agreed to discuss settlement and the Company will appeal if the case does not settle.

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 2012. In December 2012, a jury verdict was received in favor of King County in the amount of $155.8 million and a verdict in favor of VPFK in the amount of $26.3 million. VPFK will appeal if the parties are unable to reach a settlement.

The ultimate financial impact of King County’s lawsuit is not yet specifically determinable. In the fourth quarter of 2012, management developed a range of possible outcomes and has recorded a charge to income and a contingent liability of $5.0 million in accrued expenses. In developing a range of possible outcomes, management considered the jury verdict, continued litigation and potential settlement strategies. Management determined that there was no estimate within the range of possible outcomes that was more probable than the other and recorded a liability at the low end of the range. Estimating and recording future outcomes of litigation proceedings require significant judgement and assumptions about the future, which are inherently subject to risks and uncertainties. If a final recovery turns out to be materially less favorable than our estimates, this may have a significant impact on the Company's financial results. 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. In November 2012, the Court granted FSE's petition to confirm the arbitration award and denied Transit Technologies's cross-petition to vacate the award. FSE is in process of entering judgment. The eventual resolution of this matter is not expected to have a material effect on the Company’s consolidated financial statements.

[11] Stock-Based Compensation

(a) Tutor Perini Corporation Long-Term Incentive Plan

The Company is authorized to grant up to 6,900,000 stock-based compensation awards to key executives, employees and directors of the Company under the Tutor Perini Corporation Long-Term Incentive Plan (the “Plan”). The Plan allows stock-based compensation awards to be granted in a variety of forms, including stock options, stock appreciation rights, restricted stock awards, unrestricted stock awards, deferred stock awards and dividend equivalent rights. The terms and conditions of the awards granted are established by the Compensation Committee of the Company’s Board of Directors who also administers the Plan.

A total of 434,399 shares of common stock are available for future grant under the Plan at December 31, 2012.

Restricted Stock Awards

Restricted stock awards generally 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).

Approximately 245,000 of the unvested restricted stock awards will vest based on the satisfaction of service requirements and 1,785,001 will vest based on the satisfaction of both service requirements and the achievement of pre-tax income 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 December 31, 2012, the Compensation Committee has approved an aggregate of 2,365,465 stock option awards to eligible participants.

[13] Business Segments

The Company’s chief operating decision maker is the Chairman and Chief Executive Officer who decides how to allocate resources and assess performance of the business segments. Generally, the Company evaluates performance of its operating segments on the basis of income from operations and cash flow.

As discussed in Note 4 – Goodwill and Other Intangible Assets, the Company completed a reorganization in 2011 which resulted in the formation of the Specialty Contractors reporting segment. The Specialty Contractors reporting segment consists of the following subsidiary companies: WDF, FSE, Nagelbush, Fisk, DMI (all previously included in the Building reporting segment), and Superior Gunite (previously included in the Civil reporting segment). The reorganization enabled the Company to focus on vertical integration through increased self-performed work capabilities while maintaining the specialty contractors business with third parties, and strengthened the Company’s position as a full-service contractor with greater control over scheduled delivery and risk management.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Tutor Perini Corporation

Sylmar, California

We have audited the accompanying consolidated balance sheets of Tutor Perini Corporation and subsidiaries (the "Company") as of December 31, 2012 and 2011, and the related consolidated statements of income, comprehensive income, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2012. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Tutor Perini Corporation and subsidiaries as of December 31, 2012 and 2011, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2012, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company's internal control over financial reporting as of December 31, 2012, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 22, 2013 expressed an unqualified opinion on the Company's internal control over financial reporting.
