Backlog



Backlog

in our industry is a measure of the total value of work that is remaining to be performed on contracts awarded. We include a construction project in our backlog at such time aswhen a contract is awarded or a letter of commitment is obtained and we believe adequate construction funding is in place. As a result, we believe theour backlog figures areis firm, subject only to the cancellation provisions containedand although cancellations or scope adjustments may occur, historically they have not been material. Our backlog by segment, end market and customer type is presented 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, 2014 and 2013. In accordance with the accounting guidance on segment reporting, the Company has restated the comparative prior period information for the reorganized reportable segments:following tables:











We estimate that approximately $3.7$3.4 billion, or 47.8%54%, of our backlog atas of December 31, 20142016 will be recognized as revenue in 2015.2017.





Backlog by end market for the Civil segment as of December 31, 2014 and 2013 is set forth below:









Backlog by end market for the Building segment as of December 31, 2014 and 2013 is set forth below:







Backlog by end market for the Specialty Contractors segment as of December 31, 2014 and 2013 is set forth below:



We have seen over the past several years a significant shift in the mix of our customers from private to state and local government agencies, which has corresponded with an increased share of our Civil segment’s contributions to revenues and operating profits over the period. We intend to continue our focus on increasing our share of higher-margin public works and specialty contracting projects  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 continued to experience strong 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 and resources required to perform the work. As a result, on these larger projects we face fewer competitors, as smaller contractors are unable to effectively compete or are unable to secure bonding to support large projects.

In our Civil segment, we compete principally with large civil construction firms, including Dragados USA, Flatiron Construction Corp., Fluor Corp., Granite Construction, Kiewit Corp., Skanska USA, Traylor Bros., Inc., and The Walsh Group. In certain end markets of the Building segment, such as hospitality and gaming and multi-unit residential, 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 AECOM (through its acquisitions of Tishman Construction and Hunt Construction Group), Balfour Beatty Construction, Clark Construction Group, DPR Construction, Gilbane, Inc., Hensel Phelps Construction Co., McCarthy Building Companies, Inc., Skanska USA, Turner Construction Co., The Walsh Group, and The Whiting-Turner Contracting Co. In our Specialty Contractors segment, we compete principally with various regional electrical, mechanical, and plumbing subcontractors. 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 fixed price, guaranteed maximum price, and cost plus fee contracts. These contract types and the risks generally inherent therein are discussed below:follows:



Historically,Fixed price contracts account for 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, FP contracts have accounted for an increasingsubstantial portion of our revenues since 2008revenue and are expected to continue to represent a sizeable percentage of both total revenuesrevenue and backlog. The composition of revenuesrevenue and backlog by type of contract for fiscal years2016, 2015 and 2014 2013 and 2012 is as follows:













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, profitability expectations, 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.Competition



DuringThe markets in which we compete include numerous competitors. In the ordinary course of most projects, the customer, and sometimes the contractor, initiate modifications or changessmall to the original contractmid-sized work that we have targeted, we have continued 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 priceexperience strong pricing competition from our competitors. Much of the work to be performed. This process may result in disputes over whether the work performedthat we target, however, is beyond the scopefor larger, more complex projects where there are fewer active market participants because of the work includedenhanced capabilities and resources required to perform the work. As a result, on these larger projects we typically face fewer competitors. Despite this, over the past two years we have seen increased competition especially from foreign competitors that have been pursuing major projects in the original project plansUnited States due to the relatively larger size and specifications or, if the customer agreessignificant number of U.S. opportunities. We anticipate that the work performed qualifies as extra work, the price the customer is willing to payincreased level of foreign competition will persist 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.foreseeable future.



In our Civil segment, we compete principally with large civil construction firms, including (alphabetically) Dragados USA; Fluor Corporation; Granite Construction; Kiewit Corporation; Skanska USA; Traylor Bros., Inc.; and The process for resolving claims varies from one contract to another, but, in general,Walsh Group. In our Building segment, we attempt to resolve claims at the project supervisory level through the normal change order process orcompete 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. Regardlessnational and regional contractors. Our primary competitors are (alphabetically) AECOM (through its acquisitions of the process,Tishman Construction and Hunt Construction Group); Balfour Beatty Construction; Clark Construction Group; DPR Construction; Gilbane, Inc.; Hensel Phelps Construction Co.; McCarthy Building Companies, Inc.; Skanska USA; Suffolk Construction; and Turner Construction Company. In our Specialty Contractors segment, we compete principally with various regional and local electrical, mechanical and plumbing subcontractors. We believe price, experience, reputation, responsiveness, customer relationships, project completion track record, schedule control, risk management and quality of work are key factors customers consider when a potential claim arises on a project, we typically have the contractual obligation to perform the work and incur the related costs. It is not uncommon for the claim resolution process to last months or years, especially if it involves litigation.awarding contracts.



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 customer’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 project contracts often 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 ifIf 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. OnIn our fixed price contracts, we attempt to insulate ourselves from the unfavorable effects of inflation, when possible, 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, and when possible, by purchasing required materials early in the project schedule. 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 workLabor resources for our domestic projects are largely obtained through various labor unions with which we are associated. We have not experienced significant labor shortages in selected overseas areas primarily employsrecent years, nor do we expect to in the future. We employ expatriate and local labor which can usually be obtained as required.in selected overseas areas.



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,discharges; air emissions,emissions; the use, management and disposal of solid or hazardous materials or wasteswastes; 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 stormwater runoff 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 environmental laws and regulations, and we continually evaluate whether we must take additional steps to ensure compliance with environmental laws; however,those laws and regulations. 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 generated waste at, or sent waste 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 orand where we have worked as a contractor in the past, and we have incurred costs for the investigation orand remediation of hazardous substances. We believe that our liabilityliabilities for these sites willare not be material, either individually or in the aggregate, andaggregate. We have pollution liability insurance availablecoverage for such matters. We believe thatmatters, and 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.remediation.



Insurance and Bonding



All of our properties and equipment, both directly owned and owned throughas well as those of our 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. Our wholly owned subsidiary, PCR Insurance Company, issues deductible reimbursement policies for subcontractor default insurance, auto liability, general liability and workers’ compensation insurance, allowing us to centralize our claims and risk management functions to reduce our insurance-related costs.



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 payment of subcontractors and suppliers and to guarantee their performance. Historically,As an alternative to traditional surety bonds, we also have purchased contractsubcontractor default insurance onfor 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. 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.default.



Employees



The total number of personnel employed by us is subject to seasonal fluctuations,our employees varies based on the volume of construction in progress and the relative amount of work performed by subcontractors. Our average number of full-time equivalent employees during 2014 was 10,532,active projects, the type and magnitude of those projects, as well as our position within the lifecycle of those projects. Our total number of employees atas of December 31, 20142016 was 10,939.  The increase in the average from 9,679 in 2013 to 10,532 in 2014 is primarily due to business growth and normal fluctuation in job timing.11,603.  



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,projects; accordingly, 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, 2014,  approximately 7,145 of our total of 10,939 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 known and unknown risks and uncertainties that could materially adversely affecthave a material adverse effect on our operations. Set forth below, and elsewhere in this report, and in other documents we file with the SEC are descriptions of the risks and uncertainties that could cause our actual results to differ materially from the results contemplated by the forward-looking statements contained in this report. Additional risks we do not yet know of or that we currently think are immaterial may also affect our business operations. These risksreport and could have a material adverse effect on our financial condition, results of operations and cash flows.



A significant slowdown or decline in economic conditions could adversely affect our operations.

Any significant decline in economic conditions in any of the markets we serve or uncertainty regarding the economic outlook, could result in a decline in demand for infrastructure projects and commercial building developments. In addition, any instability in the financial and credit markets could negatively impact our customers’ ability to pay us on a timely basis, or at all, for work on projects already under construction, could cause our customers to delay or cancel construction projects in our backlog or could create difficulties for customers to obtain adequate financing to fund new construction projects. Such consequences could have an adverse impact on our future operating results. Lastly, we are more susceptible to adverse economic conditions in New York and California, as a significant portion of our operations are concentrated in those states.

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

Accounting for contract related revenue and costs requires management to make significant estimates and assumptions that may change significantly throughout the project lifecycle, resulting in a material impact to our consolidated financial statements. In addition, cost overruns on fixed price and GMP contracts may result in lower profits or losses.

Our contracts require us to perform extra, or change order, work, which can result in disputes or claims 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 may result in disputes or claims over whether the work performed is beyond the scope of work directed by the customer and/or exceeds the price the customer is willing to pay for the work performed. To the extent we do not recover our costs for this work or there are delays in the recovery of these costs, our cash flows and working capital could be adversely impacted.

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 Note 7 of the Notes to Consolidated Financial Statements. 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, which are inherently subject to risks and uncertainties, regarding potential outcomes of legal proceedings in order to determine an appropriate contingent liability and charge to income. Any result that is materially different than our estimates could have a material adverse effect on our financial condition, results of operations and cash flows. In addition, any adverse judgments could harm our reputation and preclude us from bidding on future projects.

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.

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

New project awards are determined through either a competitive bid basis or on a negotiated basis. Projects are generally awarded based upon price but often take into account other factors, such as technical approach and qualifications, duration of project execution and past performance on similar projects completed. Within our industry, we compete with many international, 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 resources than we do. If we are unable to compete successfully in such markets, our relative market share and profits could be reduced.

We may not fully realize the revenue value reported in our backlog.backlog due to cancellations or reductions in scope.



As of December 31, 2014,2016, our backlog of uncompleted construction work was approximately $7.8$6.2 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, suspendedthe cancellation or reducedreduction 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 aof any 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 adverse effect on future revenues, profits,our financial condition, results of operations and cash flows.



A significant slowdown or decline in economic conditionsWe have a substantial amount of indebtedness which could adversely affect our operations.financial position and prevent us from fulfilling our obligations under our debt agreements.



Although economic conditionsWe currently have, and expect to continue to have, a substantial amount of indebtedness. As of December 31, 2016, we had total debt of $759.5 million. If we are unable to meet the terms of the financial covenants or fail to comply with any of the other restrictions contained in the agreements governing our indebtedness, an event of default could occur, causing the debt related to such agreement to become immediately due. If such acceleration occurs, we may not be able to repay such indebtedness as required. Since indebtedness under our Credit Agreement is secured by substantially all of our assets, acceleration of this debt could result in foreclosure of those assets and a negative impact on our operations. In addition, a failure to meet the terms of our Credit Agreement could result in a reduction of future borrowing capacity under the Credit Agreement, causing a loss of liquidity. A loss of liquidity could adversely impact our ability to execute projects in our backlog, obtain new projects, engage subcontractors, and attract and retain key employees.

Our actual results could differ from the assumptions and estimates used to prepare our financial statements.

In preparing our financial statements, we are required under accounting principles generally accepted in the United States have gradually improved over the past two years following several challenging years during the aftermath(“GAAP”) to make estimates and assumptions as of the global economic downturn in 2008, any significant slowdown or decline in economic conditions could result in renewed demand uncertainty across various partsdate of the country, particularlyfinancial statements. These estimates and assumptions affect the reported values of assets, liabilities, revenue and expenses, and the disclosure of contingent assets and liabilities. Areas requiring significant estimates by our management include, but are not limited to:

• recognition of contract revenue, costs, profits or losses in applying the principles of percentage-of-completion accounting;

• recognition of revenue related to project incentives or awards we expect to receive;

• recognition of recoveries under contract change orders or claims;

• estimated amounts for new commercial building developmentsexpected project losses, warranty costs, contract close-out or renovations to existing infrastructure. In addition, any renewed tightness in theother costs;

• collectability of billed and unbilled accounts receivable;

• asset valuations;

• income tax provisions and related valuation allowances;

• determination of expense and potential liabilities under pension and other post-retirement benefit programs; and

• accruals for other estimated liabilities, including litigation and insurance revenue/reserves.

Our actual business and financial and credit marketsresults could create difficulties for some customers, including certain private owners and state and local governments, to obtain adequate financing to fund new construction projects on satisfactory terms or at all. These financing difficulties may significantly increase the rate atdiffer from our estimates of such results, which our customers defer, delay, or cancel proposed new construction projects. Such deferrals, delays or cancellations could have an adversea material negative impact on our future operating results.financial condition and reported results of operations.



Any renewed instability or worsening conditions in the financial and credit markets could 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. If credit markets tighten and challenging economic conditions return, lenders may become 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 states compared to others.

Reductions in the level of consumer spending within the non-residential building industry and theThe 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,The civil construction and public-works building markets are dependent on the amount of infrastructure work funded by various government agencies, which in turn, depends on many factors, including the condition of the existing infrastructure and buildings; the need for new or expanded infrastructure and buildings; and federal, state orand local government spending levels. A slowdownAs a result, our future operating results could be negatively impacted by any decrease in economic activity in any of the markets that we serve may result in less spending ondemand for public works projects. In addition, aprojects or decrease or delay in government funding, which could result from a variety of infrastructure projects orfactors, including delays in the sale of voter-approved bonds, 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 states in which the Company is involved in significant infrastructure projects and anyor long-term impairment in the ability of state and local governments to finance construction projects by raisingraise capital in the municipal bond marketmarket.

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

Many of our contracts are subject to specific completion schedule requirements. Any failure to meet contractual schedule requirements could subject us to liquidated damages, liability for our customer’s actual cost arising out of our delay the fundingand damage to our reputation.

We require substantial personnel, including construction and project managers and specialty subcontractor resources to execute and perform our contracts in backlog. The successful execution of future projects. Our Building segmentour business strategies is also involveddependent upon our ability to attract, retain and implement succession plans for key officers.

Our ability to execute and perform on our contracts in significant public worksbacklog depends in large part upon our ability to hire and retain highly skilled personnel, including project and construction management and trade labor resources, such as carpenters, masons and other skilled workers. In the event we are unable to attract, hire and retain the requisite personnel and subcontractors necessary to execute and perform our backlog, we may experience delays in completing projects in accordance with project schedules or an increase in expected costs, both of which could have a material adverse effect on our financial results, our reputation and our relationships. 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.

The execution of our business strategies also substantially depends on our ability to retain several key members of our management. Losing any of these individuals could adversely affect our business. The majority of these key officers are not bound by employment agreements. Volatility or lack of positive performance in our stock price may adversely affect our ability to retain key staff to whom we have provided share-based compensation. Additionally, because a substantial portion of our key executives' compensation is placed "at risk" and linked to the performance of our business, when our operating results are negatively impacted, we are at greater risk of employee turnover. If we lose our existing key executives and are unable to execute a succession plan our operating results would likely be harmed.

Systems and information technology interruption and breaches in data security could adversely impact our ability to operate and negatively impact our operating results.

We are reliant on computer and other information technology that could be interrupted or damaged by a variety of factors including, healthcare facilities, educational facilities,but not limited to, cyber-attacks, natural disasters, power loss, telecommunications failures, acts of war, computer viruses and municipalphysical damage. The resulting consequences could include a loss of critical data, a delay in operations or an unintentional disclosure of confidential information, any of which could have a material impact to our Company and government facilitiesits consolidated financial statements.

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 risk profile while enhancing the execution capability and financial reward of project teams. 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

primarilyperformance issues, the customer may terminate the project, which could result in Californialegal liability to us, harm our reputation, reduce our profit on a project or, in some cases, result in a loss.

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.

Failure to comply with laws and regulations related to government contracts could result in contract termination, suspension or debarment from contracting with the southeastern United States. These projects also are dependentU.S. government, civil fines and criminal prosecution, any of which could have a material impact on our consolidated financial statements and future financial condition and performance.

Conversion of our outstanding Convertible Notes could dilute ownership interests of existing stockholders and could adversely affect the market price of our common stock.

Based on the terms of the indenture for the Convertible Notes, we may redeem the Convertible Notes in cash, shares of our common stock or a combination of the two. As a result, a conversion of some or all of the Convertible Notes may dilute the ownership interests of existing stockholders. Any sales in the public market of our common stock issuable upon fundingsuch conversion of the Convertible Notes could cause the price of our common stock to decline. In addition, the existence of the Convertible Notes may encourage short selling by various federal, state and local government agencies. Amarket participants because a conversion of the Convertible Notes could depress the price of our common stock.

We may need to include the potential dilutive impact of our Convertible Notes in our diluted earnings per share calculation.

We currently intend to pay the principal amount of our Convertible Notes in cash; therefore, we have not included the potential dilutive effect of our Convertible Notes in our diluted earnings per share calculations. If, however, there is a change in future circumstances as a result of a decline in our projected cash flow or for other reasons, we may conclude at such time that it will be preferable to use shares to satisfy the Convertible Notes. Such a change in our intentions would result in the inclusion of the potential dilutive impact of the Convertible Notes in our diluted earnings per share calculation, which would result in a decrease in government funding of public healthcareour diluted earnings per share.

Economic,Our international operations expose us to economic, political and other risks, and the level ofas well as uncertainty related to U.S. Government funding, associated with our international operationswhich could adversely affect our revenuesrevenue and earnings. In addition, we could be adversely affected by violations of the U.S. Foreign Corrupt Practices Act and similar worldwide anti-bribery laws.



We derived approximately 4% or $168.8 million of revenues and approximately $27.7 million of income from construction operations forFor the year ended December 31, 20142016, we derived approximately $170.7 million of revenue from our work on projects located outside of the United States, including projects in Afghanistan, Guam, and the Philippine Islands.States. Our international operations expose us to risks inherent in doing business in certain hostile regions outside the United States, including:including political risks,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; logistical challenges; 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 revenuesrevenue and income from construction operations in key international markets.



The U.S. federal government has approved various spending bills for the construction of defense- and diplomacy-related projects and has allocated significant funds to the defense of U.S. interests around the world from the threat of terrorism. The federal government has also approved funds for development in conjunction with the relocation of military personnel into Guam. However, federal government funding levels for construction projects in the Middle East have decreased significantly over the past fewseveral years as the U.S. government has reduced the number of military troops and support personnel in the region. As a result, we have seen a decrease in the number and size of federal government projects available to us in this region. Any decrease in U.S. federal government funding for projects in Guam or in other U.S. Territories or countries in which we are pursuing work may result in project delays or cancellations, which could reduce our revenuesrevenue and earnings.



CompetitionFinally, the U.S. Foreign Corrupt Practices Act (“FCPA”), the U.K. Bribery Act of 2010, and similar anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments for new project awardsthe purpose of obtaining or retaining business. While our policies mandate compliance with these anti-bribery laws, there is intenseno assurance that our internal control policies and our failure to compete effectivelyprocedures will protect us from circumstances or actions that could reduce our market shareresult in possible criminal penalties or other sanctions, including contract cancellations or debarment 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 oftentimes take into account other factors, such as technical approach and/or qualifications, shorter project schedules, or our recordloss of past performance on similar projects completed. Within our industry, we compete with many national, regional and local construction firms. Somereputation, any 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, retain, and implement succession plans for 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 significant 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 effectadverse impact on our business, financial resultscondition, and harm our reputation. Further, the increased demand for personnel and specialty subcontractors may result in higher than expected costs, which could cause us to exceed the budget on a project. This, 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 thisoperations.

risk has been somewhat mitigated through the specialty contracting capabilities which we acquired in 2011, we still rely significantly on 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.

Volatility or lack of positive performance in our stock price and the overall markets may adversely affect our ability to retain key staff who have received equity compensation. Additionally, because a substantial portion of our key executives' compensation is placed "at risk" and linked to the performance of our business, when our operating results are negatively impacted, we are at a competitive disadvantage for retaining and hiring key executives and managers compared to other companies that may pay a relatively higher fixed salary. If we lose our existing key executives or managers or are unable to hire and integrate new key executives or managers, or if we fail to implement succession plans for our key executives, our operating results would likely be harmed.

Weather can significantly affect our revenues and profitability.

Our ability to perform work is significantly affected by weather conditions such as precipitation and temperature. Changes in weather conditions can cause delays and otherwise significantly affect our project costs. The impact of weather conditions can result in variability in our revenues and profitability.

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, reduce our profit on a project or, in some cases, result in a loss.

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 an unfavorable 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 Note1 — 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.

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 three principal types of contracts with our customers: fixed price contracts, guaranteed maximum price contracts and cost plus fee contracts. We derive a significant portion of our Civil and Specialty Contractors segment revenues and backlog from fixed price 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.

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.

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, 2014, these plans were underfunded by approximately $35.0 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 2014, we contributed $5.2 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- in 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 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 impairmentsimpairment charges in the future.



We had approximately $685.3$635.4 million of goodwill and indefinite-lived intangible assets recorded on our Consolidated Balance Sheet atas of December 31, 2014. 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.2016. We test goodwill and intangibleassess these assets for impairment by applyingannually, or more often if required. Our assessments involve a fair value test in the fourth quarternumber of each yearestimates and between annual tests if events or circumstances change which suggestassumptions that the goodwill or intangible assets should be evaluated. For example, if our market capitalization drops significantly below the amountare inherently subjective, require significant judgment and regard highly uncertain matters that are subject to change. The use 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 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 indifferent assumptions or estimates cancould materially affect the determination of fair value. If we determine, based on our assumptions, judgments, estimates and projections, that noas to whether or not an impairment exists as of a specific date, andhas occurred. In addition, if future events turn out to be materiallyare less favorable than what we assumed or estimated in assessing fair value when we tested forour impairment analysis, we may be required atto record impairment charge, which could have 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 intangible assets. If we were required to write down all or a significant part of our goodwill and 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) renewed deterioration 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.

Basedmaterial impact on our annual review of our goodwill and intangible assets, which we performed in the fourth quarter of 2014, we concluded that no impairment had occurred. To the extent that the value of the goodwill or other intangible assets becomes impaired in the future, we will be required to incur non-cash charges relating to the impairment and recognized them in our Consolidated Statement of Operations.consolidated financial statements.



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. 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 continue to 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.

As of December 31, 2014,2016, our chairman and chief executive officer, Ronald N. Tutor, and twothree trusts controlled by Mr. Tutor (the “Tutor Group”) owned approximately 17.3%18% of the outstanding shares of our common stock. Under the terms of Mr. Tutor’s employment agreement, he has the right to designate one nominee for election as a member 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, there are eleven10 current directors, one of whom was appointed by Mr. Tutor in November 2013. Mr. Tutor will 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.

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 $250 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, 2014, we had a total debt of $865.4 million, consisting of $298.8 million of senior unsecured notes (net of unamortized debt discount of $1.2 million) (the “Senior Notes”), $130.0 million of outstanding borrowings on a revolving credit basis (the “Revolving Facility”), a $250 million term loan (the “Term Loan”) which has been paid down to $242.5 million at December 31, 2014, and $194.1 million of other debt. We may also incur significant additional indebtedness in the future.

Our Senior Notes and revolving credit facility impose operating and financial restrictions on us and limit our ability to incur indebtedness from other sources without consent. Our revolving credit facility contains financial covenants that require us to maintain minimum fixed charge coverage and maximum consolidated leverage ratios. Our ability to borrow funds for any purpose is dependent upon satisfying these tests.

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 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.

Systems and information technology interruption and breaches in data security could adversely impact our ability to operate and our operating results.

We are reliant on computer and information technology and systems to properly operate. From time to time, we experience system interruptions and delays. If we are unable to add required software and hardware, effectively upgrade our systems and network infrastructure, and take other steps to improve the efficiency of and protect our systems, systems operation could be interrupted or delayed, or data security could be breached. If any of our key software vendors discontinue further development, integration, or long-term software maintenance support for our systems, or there is any significant system interruption, delay, breach of security, loss of data, or loss of a vendor, we may need to migrate our data to other systems. In addition, our systems and operations could be damaged or interrupted by natural disasters, power loss, telecommunications failures, acts of war or terrorism, acts of God, computer viruses, physical or electronic break-ins, and similar events or disruptions, including breaches by computer hackers and cyber-terrorists. Any of these or other events could cause loss of critical data, delay or prevent operations, or result in the unintentional disclosure of information. While management has taken steps to address these concerns by implementing state-of-the-art network and end-point security, internal control measures, and redundant backups of key data, a system failure or loss or data security breach could materially adversely affect our financial condition and operating results.
