Operations
The electrical and mechanical construction services industry has grown over the years due principally to the increased content, complexity and sophistication of electrical and mechanical systems, as well as the installation of more technologically advanced voice and data communications, lighting, and environmental control systems in all types of facilities, in large part due to the integration of digital processing and information technology. For these reasons, buildings need extensive electrical distribution systems. In addition, advanced voice and data communication systems require sophisticated power supplies and extensive low-voltage and fiber-optic communications cabling. Moreover, the need for substantial environmental controls within a building, due to the heightened need for climate control to maintain extensive computer systems at optimal temperatures, and the demand for energy savings and environmental controlcontrols in individual spaces have over the years expanded opportunities for our electrical and mechanical services businesses. The demand for these services is typically driven by non-residential construction and renovation activity.

Electrical and mechanical construction services primarily involve the design, integration, installation and start-up, and provision of services relating to: (a) electric power transmission and distribution systems, including power cables, conduits, distribution panels, transformers, generators, uninterruptible power supply systems and related switch gear and controls; (b) premises electrical and lighting systems, including fixtures and controls; (c) process instrumentation in the refining, chemical process, food process and mining industries; (d) low-voltage systems, such as fire alarm, security and process control systems; (d)(e) voice and data communications systems, including fiber-optic and low-voltage cabling; (e)(f) roadway and transit lighting and fiber-optic lines; (f)(g) heating, ventilation, air conditioning, refrigeration and clean-room process ventilation systems; (g)(h) fire protection systems; (h)(i) plumbing, process and high-purity piping systems; (i)(j) controls and filtration systems; (j)(k) water and wastewater treatment systems; (k)(l) central plant heating and cooling systems; (l)(m) cranes and rigging; (m)(n) millwrighting; and (n)(o) steel fabrication, erection and welding.
Electrical and mechanical construction services generally fall into one of twothree categories: (a) large installation projects with contracts often in the multi-million dollar range that involve construction of manufacturing and commercial buildings and institutional and public works projects or the fit-out of large blocks of space within commercial buildings, (b) large and (b)medium sized capital and maintenance projects for manufacturing, petrochemical, oil and industrial clients and (c) smaller installation projects typically involving fit-out, renovation and retrofit work.
Our United States electrical and mechanical construction services operations accounted for about 53%54% of our 20132016 revenues, approximately 67%62% of which were related to new construction and approximately 33%38% of which were related to renovation and retrofit projects. Our United Kingdom electrical and mechanical construction services operations accounted for approximately 2% of our 2013 revenues, approximately 46% of which were related to new construction and approximately 54% of which were related to renovation and retrofit projects. However, in mid-2013, we announced our decision to end our construction operations in the United Kingdom due to recurring losses over the last several years and our negative assessment of construction market conditions in the United Kingdom. We plan to focus in the United Kingdom solely on building services.
We provide electrical and mechanical construction services for both large and small installation and renovation projects. Our largest projects have included those: (a) for institutional purposes (such as educational and correctional facilities and research laboratories); (b) for manufacturing purposes (such as pharmaceutical plants, steel, pulp and paper mills, chemical, food, automotive and semiconductor manufacturing facilities and power generation); (c) for transportation purposes (such as highways, bridges, airports and transit systems); (d) for commercial purposes (such as office buildings, data centers, convention centers, sports stadiums and shopping malls and resorts)malls); (e) for hospitality purposes (such as resorts, hotels and casinos); (f) for water and wastewater purposes; and (g) for healthcare purposes.purposes; (h) for process facilities such as oil and gas refineries and chemical processing plants; and (i) for oil and gas pipeline compressor stations and terminal and metering facilities. Our largest projects, which typically range in size from $10.0 million up to and occasionally exceeding $150.0 million and are frequently multi-year projects, represented approximately 33%29% of our worldwide construction services revenues in 2013.2016.
Our projects of less than $10.0 million accounted for approximately 67%71% of our worldwide construction services revenues in 2013.2016. These projects are typically completed in less than one year. They usually involve electrical and mechanical construction services when an end-user or owner undertakes construction or modification of a facility to accommodate a specific use. These projects frequently require electrical and mechanical systems to meet special needs such as critical systems power supply, fire protection systems, special environmental controls and high-purity air systems, sophisticated electrical and mechanical systems for data centers, new production lines in manufacturing plants, and office arrangements in existing office buildings. They are not usually dependent upon the new construction market. Demand for these projects and types of services is often prompted by the expiration of leases, changes in technology, or changes in the customer'scustomer’s plant or office layout in the normal course of a customer'scustomer’s business.
We have a broad customer base with many long-standing relationships. We perform construction services pursuant to contracts with owners such(such as corporations, municipalities and other governmental entities,entities), general contractors, systems suppliers, construction managers, developers, other subcontractors and tenants of commercial properties. Institutional and public works

3


projects are frequently long-term complex projects that require significant technical and management skills and the financial strength to obtain bid and performance bonds, which are often a condition to bidding for and winning these projects.
We also install and maintain lighting for streets, highways, bridges and tunnels, traffic signals, computerized traffic control systems, and signal and communication systems for mass transit systems in several metropolitan areas. In addition, in the United States, we manufacture and install sheet metal air handling systems for both our own mechanical construction operations and for unrelated mechanical contractors. We also maintain welding and pipe fabrication shops in support of some of our mechanical operations.
Our United States building services segment offers a broad range of services, including operation, maintenance and service of electrical and mechanical systems; commercial and government site-based operations and maintenance; facility maintenance and services, including outage services to utilities and manufacturing facilities; military base operations support services; mobile mechanical maintenance and services; floor care and janitorial services; landscaping, lot sweeping and snow removal; facilities management; vendor management; call center services; installation and support for building systems; program development, management and maintenance with respect to energy systems; technical consulting and diagnostic services; infrastructure and building projects for federal, state and local governmental agencies and bodies; and small modification and retrofit projects; and retrofit projects to comply with clean air laws.projects.

These building services, which generated approximately 37%31% of our 20132016 revenues, are provided to owners, operators, tenants and managers of all types of facilities both on a contract basis for a specified period of time and on an individual task order basis. Of our 20132016 building services revenues, approximately 88%89% were generated in the United States and approximately 12%11% were generated in the United Kingdom.
Our building services operations have built upon our traditional electrical and mechanical services operations facilities services activities of our electrical and mechanical contracting subsidiaries, and our client relationships as well as acquisitions, to expand the scope of services being offered and to develop packages of services for customers on a regional and national basis.
Demand for our building services is often driven by customers'customers’ decisions to focus on their core competencies, customers'customers’ programs to reduce costs, the increasing technical complexity of their facilities and their mechanical, electrical, voice and data and other systems, and the need for increased reliability, especially in electrical and mechanical systems. These trends have led to outsourcing and privatization programs whereby customers in both the private and public sectors seek to contract out those activities that support, but are not directly associated with, the customer'scustomer’s core business. Clients of our building services business include federal and state governments, utilities, independent power producers, pulp and paper producers, and major corporations engaged in information technology, telecommunications, pharmaceuticals, financial services, publishing and other manufacturing, and large retailers and other businesses with multiple locationsgeographically dispersed portfolios throughout the United States.
We currently provide building services in a majority of the states in the United States to commercial, industrial, institutional and governmental customers and as part of our operations are responsible for: (a) the oversight of all or most of the facilities operations of a business, including operation and maintenance; (b) servicing, upgrade and retrofit of HVAC, electrical, plumbing and industrial piping and sheet metal systems in existing facilities; (c) interior and exterior services, including floor care and janitorial services, landscaping, lot sweeping and snow removal; (d) diagnostic and solution engineering for building systems and their components; and (e) maintenance and support services to manufacturers and power producers.
In the Washington D.C. metropolitan area, we provide building services at a number of preeminent buildings, including those that house the Secret Service, The Federal Deposit Insurance Corporation, the National Foreign Affairs Training Center, and the Department of Health and Human Services, as well as other government facilities, including the NASA Jet Propulsion Laboratory in Pasadena, California. We also provide building services to a number of military bases, including base operations support services to the Navy National Capital Region and the Army'sArmy’s Fort Huachuca, Arizona, and are also involved in a joint venturesventure providing building services to the Naval Support Activity Mid-South Base Kitsap in the State of Washington.Tennessee. The agreements pursuant to which this division provides services to the federal government are frequently for a termbase year and a number of fiveoption years exercisable at the sole discretion of the government, are often subject to renegotiation of terms and prices by the government in terms of scope of services, and are subject to termination by the government prior to the expiration of the applicable term.
Our United Kingdom subsidiary primarily focuses on building services and currently provides a broad range of services under multi-year agreements to public and private sector customers, including airlines, airports, real estate property managers, manufacturers and governmental agencies.
Our industrial services business, which generated approximately 14% of our 2016 revenues, is a recognized leader in the refinery turnaround market and has a growing presence in the petrochemical market. In July 2013, we acquired RepconStrickland, Inc., expanding services we provide to our refinery and petrochemical customers and significantly increasing the size of our industrial services business. Our industrial services business: (a) provides after-market maintenance, repair and cleaning services for highly engineered shell and tube heat exchangers for refineries and petrochemical plants both in the field and at our own shops, including tube and shell repairs, bundle repairs, and

4


extraction services, and (b) designs and manufactures new highly engineered shell and tube heat exchangers. We also perform a broad range of turnaround and maintenance services for critical units of refineries so as to upgrade, repair and maintain them. Such services include turnaround and maintenance services relating to: (i) engineering and planning services in advance of complex refinery turnarounds,turnarounds; (ii) overhaul and maintenance of critical process units (including hydrofluoric alkylation units, fluid catalytic cracking units, coking units, heaters, heat exchangers and related mechanical equipment) during refinery and petrochemical plant shut downs,downs; (iii) general revampsreplacement and new construction capital projects for refineries and petrochemical plants,plants; and (iv) other related specialty technical services such as (a) welding including(including pipe welding,welding) and fabrication; heater, boiler, and reformer repairs and revamps;replacements; converter repair and revamps; and vessel, exchanger and tower services; (b) tower and column repairs in refineries and revamps in refineries;petrochemical facilities; (c) installation and repair of refractory materials for critical units in process plants so as to protect equipment from corrosion, erosion, and extreme temperatures; and (d) acid-proofing services to protect critical components at refineries from chemical exposure.

Competition
In our construction services, building services and industrial services businesses, we compete with national, regional and local companies, many of which are small, owner-operated entities that carry on their businesses in a limited geographic area.area, as well as with certain foreign companies.
We believe that the electrical and mechanical construction services businesses are highly fragmented and our competition includes thousands of small companies across the United States. In the United States, there are a few public companies focused on providing either electrical and/or mechanical construction services, such as Integrated Electrical Services, Inc., Comfort Systems USA, Inc. and Tutor Perini Corporation. A majority of our revenues are derived from projects requiring competitive bids; however, an invitation to bid is often conditioned upon prior experience, technical capability and financial strength. Because we have total assets, annual revenues, net worth, access to bank credit and surety bonding and expertise significantly greater than most of our competitors, we believe we have a significant competitive advantage over our competitors in providing electrical and mechanical construction services. Competitive factors in the electrical and mechanical construction services business include: (a) the availability of qualified and/or licensed personnel; (b) reputation for integrity and quality; (c) safety record; (d) cost structure; (e) relationships with customers; (f) geographic diversity; (g) the ability to control project costs; (h) experience in specialized markets; (i) the ability to obtain surety bonding; (j) adequate working capital; (k) access to bank credit; and (l) price. However, there are relatively few significant barriers to entry to several types of our construction services business.
While the building services business is also highly fragmented, with most competitors operating in a specific geographic region, a number of large United States based corporations such as AECOM Technology Corporation, Johnson Controls, Inc., Fluor Corp., J&J Worldwide Services, DTZ, the Washington Division of URS Corporation,Cushman & Wakefield Inc., CB Richard Ellis, Inc., Jones Lang LaSalle Incorporated, Sodexo, Inc., Aramark Corporation and ABM Facility ServicesIndustries Incorporated are engaged in this field, as are large original equipment manufacturers such as Carrier Corp. and Trane Air Conditioning.Inc. In addition, we compete with several regional firms serving all or portions of the markets we target, such as FM Facility Maintenance,Brickman Valley Crest, Inc., Kellermeyer Bergensons Property Services, Inc., SMS Assist, LLC and Ferandino & Sons, Inc. Our principal services competitors in the United Kingdom include ISS UK Ltd. and MITIE Group plc. The key competitive factors in the building services business include price, service, quality, technical expertise, geographic scope and the availability of qualified personnel and managers. Due to our size, both financial and geographic, and our technical capability and management experience, we believe we are in a strong competitive position in the building services business. However, there are relatively few barriers to entry to most of our building services businesses.
In our industrial services business, we are thea leading North American provider of after-market maintenance and repair services for, and manufacturing of, highly engineered shell and tube heat exchangers and related equipment and a leader in providing specialized services to refineries and petrochemical plants. The market for providing these services and products to refineries and petrochemical plants is highly fragmented and includes large national industrial services providers, as well as numerous regional companies, including JV Industrial Companies Ltd., Matrix Service Company, Starcon, Turner Industries, Team, Inc., Cust-O-Fab, Dunn Heat, and Wyatt Field Service Company. In the manufacture of heat exchangers, we compete with both U.S. and foreign manufacturers. The key competitive factors in the industrial services market include service, quality, ability to respond quickly, technical expertise, price, safety record and availability of qualified personnel. Due to our technical capabilities, safety record and skilled workforce, we believe that we are in a strong competitive position in the industrial services market we serve. Because of the complex tasks associated with turnarounds and the precision required in the manufacture of heat exchangers, we believe that the barriers to entry in this business are significant.
Employees
At December 31, 2013,2016, we employed over 27,000approximately 31,000 people, approximately 57%55% of whom are represented by various unions pursuant to more than 375approximately 400 collective bargaining agreements between our individual subsidiaries and local unions. We believe that our employee relations are generally good. Only two of these collective bargaining agreements are national or regional in scope.

Backlog
Our backlog at December 31, 20132016 was $3.36$3.90 billion compared to $3.37$3.77 billion of backlog at December 31, 2012.2015. Backlog increases with awards of new contracts and decreases as we perform work on existing contracts. Backlog is not a term recognized under United States generally accepted accounting principles; however, it is a common measurement used in our industry. We include a project within our backlog at such time as a contract is awarded.awarded and agreement on contract terms has been reached. Backlog includes unrecognized revenues to be realized from uncompleted construction contracts plus unrecognized revenues expected to be realized over the remaining term of services contracts. However, we do not include in backlog contracts for which we are paid on a time and material basis and a fixed amount cannot be determined, and if the remaining term of a services contract exceeds 12 months, the unrecognized revenues attributable to such contract included in backlog are limited to only the next 12

months of revenues provided for in the initial contract award. Our backlog also includes amounts related to services contracts for which a fixed price contract value is not assigned; however,assigned when a reasonable estimate of total revenues can be made from budgeted amounts agreed to with our customer.customers. Our backlog is comprised of: (a) original contract amounts, (b) change orders for which we have received written confirmations from our customers, (c) pending change orders for which we expect to receive confirmations in the ordinary course of business and (d) claim amounts that we have made against customers for which we have determined we have a legal basis under existing contractual arrangements and as to which we consider collectionrecovery to be probable. ClaimSuch claim amounts recorded were immaterial for all periods presented. Our backlog does not include anticipated revenues from unconsolidated joint ventures or variable interest entities and anticipated revenues from pass-through costs on contracts for which we are acting in the capacity of an agent and which are reported on the net basis. We believe our backlog is firm, although many contracts are subject to cancellation at the election of our customers. Historically, cancellations have not had a material adverse effect on us. We estimate that 84% of our backlog as of December 31, 20132016 will be recognized as revenues during 2014.2017.

ITEM 1A. RISK FACTORS
Our business is subject to a variety of risks, including the risks described below as well as adverse business and market conditions and risks associated with foreign operations. The risks and uncertainties described below are not the only ones facing us. Additional risks and uncertainties not known to us or not described below which we have not determined to be material may also impair our business operations. You should carefully consider the risks described below, together with all other information in this report, including information contained in the “Business,” “Management's“Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Quantitative and Qualitative Disclosures about Market Risk” sections. If any of the following risks actually occur, our business, financial position, results of operations and/or cash flows could be adversely affected, and we may not be able to achieve our goals. Such events may cause actual results to differ materially from expected and historical results, and the trading price of our common stock could decline.
Economic downturns have led to reductions in demand for our services. Negative conditions in the credit markets may adversely impact our ability to operate our business. The level of demand from our clients for our services has been, in the past, adversely impacted by slowdowns in the industries we service, as well as in the economy in general. When the general level of economic

6


activity has been reduced from historical levels, certain of our ultimate customers have delayed or cancelled projects or capital spending, especially with respect to more profitable private sector work, and such slowdowns adversely affect our ability to grow, reducing our revenues and profitability. A number of economic factors, including financing conditions for the industries we serve, have, in the past, adversely affected our ultimate customers and their ability or willingness to fund expenditures. General concerns about the fundamental soundness of domestic and foreign economies may cause ultimate customers to defer projects even if they

have credit available to them. Worsening of financial and macroeconomic conditions could have a significant adverse effect on our revenues and profitability.
Many of our clients depend on the availability of credit to help finance their capital and maintenance projects. At times, tightened availability of credit has negatively impacted the ability of existing and prospective ultimate customers to fund projects we might otherwise perform, particularly those in the more profitable private sector. As a result, our ultimate customers may defer such projects for an unknown, and perhaps lengthy, period. Any such deferrals would inhibit our growth and would adversely affect our results of operations.
In a weak economic environment, particularly in a period of restrictive credit markets, we may experience greater difficulties in collecting payments from, and negotiating change orders and/or claims with, our clients due to, among other reasons, a diminution in our ultimate customers'customers’ access to the credit markets. If clients delay in paying or fail to pay a significant amount of our outstanding receivables, or we fail to successfully negotiate a significant portion of our change orders and/or claims with clients, it could have an adverse effect on our liquidity, results of operations and financial position.
Our business has traditionally lagged recoveries in the general economy and, therefore, after an economic downtown we may not recover as quickly as the economy at large.
Our business is vulnerable to the cyclical nature of the markets in which our clients operate and is dependent upon the timing and funding of new awards. We provide construction and maintenance services to ultimate customers operating in a number of markets which have been, and we expect will continue to be, cyclical and subject to significant fluctuations due to a variety of factors beyond our control, including economic conditions and changes in client spending.
Regardless of economic or market conditions, investment decisions by our ultimate customers may vary by location or as a result of other factors like the availability of labor, relative construction costs or competitive conditions in their industry.industries. Because we are dependent on the timing and funding of new awards, we are therefore vulnerable to changes in our clients'clients’ markets and investment decisions. Our business has traditionally lagged recoveries in the general economy and, therefore, may not recover as quickly as the economy at large.
Our business may be adversely affected by significant delays and reductions in government appropriations. Federal legislation adopted in 2013Curtailed spending aimed at curtailing spending byreducing federal, agenciesstate and departments and reducing the federallocal budget deficit has resulteddeficits could result in federal governmental agencies or departments deferring or canceling projects that we might otherwise have sought to perform. We expect that budgetaryBudgetary constraints and ongoing concerns regarding the U.S. national debt will continue tomay place downward pressure on spending levels of the U.S. government. In addition, significant budget deficits faced by state and local governments as a result of declining tax and other revenues may result in curtailment of future spending on their government infrastructure projects and/or expenditures. Some of our businesses derive a significant portion of their revenues from federal, state and local governmental bodies.
An increase in the prices of certain materials used in our businesses could adversely affect our businesses. We are exposed to market risk of fluctuationsincreases in certain commodity prices of materials, such as copper and steel, which are used as components of supplies or materials utilized in all of our operations. We are also exposed to increases in energy prices, particularly as they relate to gasoline prices for our fleet of over 8,5009,500 vehicles. While we believe we can increase our prices to adjust for some price increases in commodities, there can be no assurance that price increases of commodities, if they were to occur, would be recoverable. Additionally, our fixed price contracts do not allow us to adjust our prices and, as a result, increases in material or fuel costs could reduce our profitability with respect to such projects. Fluctuations in energy prices as well as in commodity prices of materials may adversely affect our customers and as a result cause them to curtail the use of our services. Recent volatility in the price of oil has caused some of our refinery customers to curtail or delay maintenance or capital projects. Further volatility in the price of oil may adversely affect some of our refinery customers causing them to defer maintenance and/or capital projects performed by companies in our United States industrial services segment or delay purchases or repairs of heat exchangers that are manufactured and repaired by some of our companies.
Our industry is highly competitive. Our industry is served by numerous small, owner-operated private companies, a few public companies and several large regional companies. In addition, relatively few barriers prevent entry into most of our businesses. As a result, any organization that has adequate financial resources and access to technical expertise may become one of our competitors.a competitor. Competition in our industry depends on numerous factors, including price. Certain of our competitors have lower overhead cost structures and, therefore, are able to provide their services at lower rates than we are currently able to provide. In addition, some of our competitors have greater resources than we do. We cannot be certain that our competitors will not develop the expertise, experience and resources necessary to provide services that are superior in quality and lower in price to ours. Similarly, we cannot be certain that we will be able to maintain or enhance our competitive position within the industryour industries or maintain a customer base at current levels. We may also face competition from the in-house service organizations of existing or prospective customers, particularly with respect to building services. Many of our customers employ personnel who perform some of the same types of building services that we do. We cannot be certain that our existing or prospective customers will continue to outsource building services in the future.

7


We are a decentralized company, which presents certain risks. While we believe decentralization has enhanced our growth and enabled us to remain responsive to opportunities and to our customers'customers’ needs, it necessarily places significant control and decision-making powers in the hands of local management. This presents various risks, including the risk that we may be slower or less able to identify or react to problems affecting a key business than we would in a more centralized environment.
Our business may also be affected by adverse weather conditions. Adverse weather conditions, particularly during the winter season, could impact our construction services operations as those conditions affect our ability to perform efficient work outdoors in certain regions of the United States, adversely affecting the revenues and the United Kingdom.profitability of those operations. However, the absence of snow in the United States during the winter could also cause us to experience reduced revenues and profitability in our United States building services segment, which has meaningful snow removal operations. In addition, cooler than normal temperatures during the summer months could reduce the need for our services, particularly in our businesses that provideinstall or service air conditioning units, and result in reduced revenues and profitability during the period such unseasonal weather conditions persist.
Our business may be affected by the work environment. We perform our work under a variety of conditions, including but not limited to, difficult terrain, difficult site conditions and busy urban centers where delivery of materials and availability of labor may be impacted, clean-room environments where strict procedures must be followed, and sites which may have been exposed to environmental hazards.harsh and hazardous conditions, especially at chemical plants, refineries and other process facilities. Performing work under these conditions can negatively affect efficiency and, therefore, our profitability.
Our dependence upon fixed price contracts could adversely affect our business. We currently generate, and expect to continue to generate, a significant portion of our revenues from fixed price contracts. We must estimate the total costs of a particular project to bid for fixed price contracts. The actual cost of labor and materials, however, may vary from the costs we originally estimated. These variations, along with other risks, inherent in performing fixed price contracts, may cause actual gross profits from projects to differ from those we originally estimated and could result in reduced profitability or losses on projects. Depending upon the size of a particular project, variations from the estimated contract costs can have a significant impact on our operating results for any fiscal quarter or year.
We could incur additional costs to cover certain guarantees. In some instances, we guarantee completion of a project by a specific date or price, cost savings, achievement of certain performance standards or performance of our services at a certain standard of quality. If we subsequently fail to meet such guarantees, we may be held responsible for costs resulting from such failures. Such a failure could result in our payment of liquidated or other damages. To the extent that any of these events occur, the total costs of a project could exceed the original estimated costs, and we would experience reduced profits or, in some cases, a loss.
Many of our contracts, especially our building services contracts for governmental and non-governmental entities, may be canceled on short notice, and we may be unsuccessful in replacing such contracts if they are canceled or as they are completed or expire. We could experience a decrease in revenues, net income and liquidity if any of the following occur:
customers cancel a significant number of contracts;
we fail to win a significant number of our existing contracts upon re-bid;
we complete a significant number of non-recurring projects and cannot replace them with similar projects; or
we fail to reduce operating and overhead expenses consistent with any decrease in our revenues.
We may be unsuccessful in generating internal growth. Our ability to generate internal growth will be affected by, among other factors, our ability to:
expand the range of services offered to customers to address their evolving needs;
attract new customers; and
retain and/or increase the number of projects performed for existing customers.
In addition, existing and potential customers in the past have reduced, and may continue to reduce, the number or size of projects available to us because of general economic conditions or due to their inability to obtain capital or pay for services provided or because of general economic conditions.we provide. Many of the factors affecting our ability to generate internal growth are beyond our control, and we cannot be certain that our strategies will be successful or that we will be able to generate cash flow sufficient to fund our operations and to support internal growth. If we are not successful, we may not be able to achieve internal growth, expand operations or grow our business.

The departure of key personnel could disrupt our business. We depend on the continued efforts of our senior management. The loss of key personnel, or the inability to hire and retain qualified executives, could negatively impact our ability to manage our business. However, we have executive development and management succession plans in place in order to minimize any such negative impact.

8


We may be unable to attract and retain skilled employees. Our ability to grow and maintain productivity and profitability will be limited by our ability to employ, train and retain skilled personnel necessary to meet our requirements. We are dependent upon our project managers and field supervisors who are responsible for managing our projects; and there can be no assurance that any individual will continue in his or her capacity for any particular period of time, and the loss of such qualified employees could have an adverse effect on our business. We cannot be certain that we will be able to maintain an adequate skilled labor force necessary to operate efficiently and to support our business strategy or that labor expenses will not increase as a result of a shortage in the supply of these skilled personnel. Labor shortages or increased labor costs could impair our ability to maintain our business or grow our revenues.
Our unionized workforce could adversely affect our operations, and we participate in many multiemployer union pension plans which could result in substantial liabilities being incurred. As of December 31, 2013,2016, approximately 57%55% of our employees were covered by collective bargaining agreements. Although the majority of these agreements prohibit strikes and work stoppages, we cannot be certain that strikes or work stoppages will not occur in the future. However, only two of our collective bargaining agreements are national or regional in scope, and not all of our collective bargaining agreements expire at the same time. Strikes or work stoppages would adversely impact our relationships with our customers and could have a material adverse effect on our financial position, results of operations and cash flows. We contribute to overapproximately 200 multiemployer union pension plans based upon wages paid to our union employees that could result in our being responsible for a portion of the unfunded liabilities under such plans. Our potential liability for unfunded liabilities could be material. Under the Employee Retirement Income Security Act, we may become liable for our proportionate share of a multiemployer pension plan'splan’s underfunding, if we cease to contribute to that pension plan or significantly reduce the employees in respect of which we make contributions to that pension plan. See Note 14 - Retirement Plans of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data for additional information regarding multiemployer plans.
Fluctuating foreign currency exchange rates impact our financial results. We have foreign operations in the United Kingdom, which in 20132016 accounted for 7%approximately 4% of our revenues. Our reported financial position and results of operations are exposed to the effects (both positive and negative) that fluctuating exchange rates have on the process of translating the financial statements of our United Kingdom operations, which are denominated in local currencies, into the U.S. dollar.
Our failure to comply with environmental laws could result in significant liabilities. Our operations are subject to various laws, including environmental laws and regulations, among which many deal with the handling and disposal of asbestos and other hazardous or universal waste products, PCBs and fuel storage. A violation of such laws and regulations may expose us to various claims, including claims by third parties, as well as remediation costs and fines. We own and lease many facilities. Some of these facilities contain fuel storage tanks, which may be above or below ground. If these tanks were to leak, we could be responsible for the cost of remediation as well as potential fines. As a part of our business, we also install fuel storage tanks and are sometimes required to deal with hazardous materials, all of which may expose us to environmental liability.
In addition, new laws and regulations, stricter enforcement of existing laws and regulations, the discovery of previously unknown contamination or leaks, or the imposition of new clean-up requirements could require us to incur significant costs or become the basis for new or increased liabilities that could harm our financial position and results of operations, although certain of these costs might be covered by insurance. In some instances, we have obtained indemnification or covenants from third parties (including predecessors or lessors) for such clean-up and other obligations and liabilities, thatand we believe such indemnities and covenants are adequate to cover such obligations and liabilities. However, such third-party indemnities or covenants may not cover all of such costs or third-party indemnitors may default on their obligations. In addition, unanticipated obligations or liabilities, or future obligations and liabilities, may have a material adverse effect on our business operations. Further, we cannot be certain that we will be able to identify, or be indemnified for, all potential environmental liabilities relating to any acquired business.
Adverse resolution of litigation and other legal and regulatory proceedings may harm our operating results or financial position. WeFrom time to time, we are a party to lawsuits and other legal proceedings, most of which occur in the normal course of our business. These actions and proceedings may involve actual or threatened claims by customers and/or employees for, among other things, compensation for alleged personal injury, workers’ compensation, employment discrimination, breach of contract, property damage or other general commercial disputes. In addition, we may be subject to class action claims alleging violations of the Fair Labor Standards Act and state wage and hour laws. Litigation and other legal proceedings can be expensive, lengthy and disruptive to normal business operations. Moreover, the results of complex legal proceedings areoperations, and their outcome is inherently uncertain and difficult to predict.accurately predict or quantify. In addition, plaintiffs in many types of actions may seek punitive damages, civil penalties, consequential damages or other losses, or injunctive or declaratory relief. An unfavorable resolution of a particular legal proceeding or claim, whether through a settlement, mediation, court judgment or otherwise, could have a material adverse effect on our business, operating results, financial position and cash flows, and in some cases, on our reputation or our ability to obtain projects from customers, including governmental entities. See

Item 3. Legal Proceedings and Note 15 - Commitments and Contingencies of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data, for more information regarding legal proceedings in which we are involved.
Opportunities within the government sector could lead to increased governmental regulation applicable to us and unrecoverable startup costs.us. Most government contracts are awarded through a regulated competitive bidding process. As we pursue increased opportunities in the government arena, particularly in our building services segment, management's focus associated with the start-up and bidding process may be diverted away from other opportunities. If we are to be successful in being awarded additional government contracts, a significant amount of costs could be required before any revenues are realized from these contracts. In addition, as a government contractor we are subject to a number of procurement rules and other regulations, any deemed violation of which could lead to fines or penalties or a loss of business. Government agencies routinely audit and investigate government

9


contractors. Government agencies may review a contractor'scontractor’s performance under its contracts, cost structure and compliance with applicable laws, regulations and standards. If government agencies determine through these audits or reviews that costs are improperly allocated to specific contracts, they will not reimburse the contractor for those costs or may require the contractor to refund previously reimbursed costs. If government agencies determine that we are engaged in improper activity, we may be subject to civil and criminal penalties and debarment or suspension from doing business with the government. Government contracts are also subject to renegotiation of profitterms by the government, termination by the government prior to the expiration of the term, and non-renewal by the government.
A significantmaterial portion of our business depends on our ability to provide surety bonds. We may be unable to compete for or work on certain projects if we are not able to obtain the necessary surety bonds. Our construction contracts frequently require that we obtain from surety companies and provide to our customers payment and performance bonds as a condition to the award of such contracts. Such surety bonds secure our payment and performance obligations. Under standard terms in the surety market, surety companies issue bonds on a project-by-project basis and can decline to issue bonds at any time or require the posting of additional collateral as a condition to issuing any bonds. Current or future market conditions, as well as changes in our sureties'sureties’ assessment of our or their own operating and financial risk, could cause our surety companies to decline to issue, or substantially reduce the amount of, bonds for our work and couldor to increase our bonding costs. These actions can be taken on short notice. If our surety companies were to limit or eliminate our access to bonding, our alternatives would include seeking bonding capacity from other surety companies, increasing business with clients that do not require bonds and posting other forms of collateral for project performance, such as letters of credit, parent company guarantees or cash. We may be unable to secure these alternatives in a timely manner, on acceptable terms, or at all. Accordingly, if we were to experience an interruption or reduction in the availability of bonding, we may be unable to compete for or work on certain projects. Increases in the costs of surety bonds could also adversely impact our profitability.
We are effectively self-insured against many potential liabilities. Although we maintain insurance policies with respect to a broad range of risks, including automobile liability, general liability, workers'workers’ compensation and employee group health, these policies do not cover all possible claims and certain of the policies are subject to large deductibles. Accordingly, we are effectively self-insured for a substantial number of actual and potential claims. In addition, if any of our insurance carriers defaulted on its obligations to provide insurance coverage by reason of its insolvency or for other reasons, our exposure to claims would increase and our profits would be adversely affected. Our estimates for unpaid claims and expenses are based on known facts, historical trends and industry averages, utilizing the assistance of an actuary. We reflect these liabilities in our balance sheet as “Other accrued expenses and liabilities” and “Other long-term obligations.” The determination of such estimated liabilities and their appropriateness are reviewed and updated at least quarterly. However, these liabilities are difficult to assess and estimate due to many relevant factors, the effects of which are often unknown, including the severity of an injury or damage, the determination of liability in proportion to other parties, the timeliness of reported claims, the effectiveness of our risk management and safety programs and the terms and conditions of our insurance policies. Our accruals are based upon known facts, historical trends and our reasonable estimate of future expenses, and we believe such accruals are adequate. However, unknown or changing trends, risks or circumstances, such as increases in claims, a weakening economy, increases in medical costs, changes in case law or legislation or changes in the nature of the work we perform, could render our current estimates and accruals inadequate. In such case, adjustments to our balance sheet may be required and these increased liabilities would be recorded in the period that the experience becomes known. Insurance carriers may be unwilling, in the future, to provide our current levels of coverage without a significant increase in insurance premiums and/or collateral requirements to cover our obligations to them. Increased collateral requirements may be in the form of additional letters of credit and/or cash, and an increase in collateral requirements could significantly reduce our liquidity. If insurance premiums increase, and/or if insurance claims are higher than our estimates, our profitability could be adversely affected.
Health care reform could adversely affect our operating results. In 2010, the United States government enacted comprehensive health care reform legislation. Due to the breadth and complexity of this legislation, as well as its phased-in nature of implementation, it is difficult for us to predict the overall effects it will have on our business over the coming years. To date, we have not experienced material costs related to the health care reform legislation; however, it is possible that our operating results and/or cash flows could be adversely affected in the future by increased costs, expanded liability exposure and requirements that change the ways we provide healthcare and other benefits to our employees.
We may incur liabilities or suffer negative financial impact relating to occupational, health and safety matters. Our operations are subject to extensive laws and regulations relating to the maintenance of safe conditions in the workplace. While we have invested, and will continue to invest, substantial resources in our robust occupational, health and safety programs, many of our industry involvesbusinesses involve a high degree of operational risk, and there can be no assurance that we will avoid significant liability exposure. These hazards can cause personal injury and loss of life, severe damage to or destruction of property and equipment and other consequential damages and could lead to suspension of operations, large damage claims and, in extreme cases, criminal liability.
Our customers seek to minimize safety risks on their sites and they frequently review the safety records of contractors during the bidding process. If our safety record were to substantially deteriorate over time, we might become ineligible to bid on certain work and our customers could cancel our contracts and/or not award us future business.

10


If we fail to integrate future acquisitions successfully, thisAcquisitions could adversely affect our business and results of operations. As part of our growth strategy, we acquire companies that expand, complement and/or diversify our business.businesses. Realization of the anticipated benefits of an acquisition will depend, among other things, upon our ability to: (a) effectively conduct due diligence on companies we propose to integrateacquire to identify problems at these companies or (b) recognize incompatibilities or other obstacles to successful integration of the acquired business successfully with our other operations and gain greater efficiencies and scale that will translate into reduced costs in a timely manner. However, there can be no assurance that an acquisition we may make in the future will provide the benefits anticipated when entering into the transaction. Acquisitions we have made and future acquisitions may expose us to operational challenges and risks, including the diversion of management'smanagement’s attention from our existing business,businesses, the failure to retain key personnel or customers of the acquired business and the assumption of unknown liabilities of the acquired business for which there are inadequate reserves and the potential impairment of acquired identifiable intangible assets, including goodwill.reserves. Our ability to sustain our growth and maintain our competitive position may be affected by our ability to identify and acquire desirable businesses and successfully integrate any business acquired.
Our results of operations could be adversely affected as a result of goodwill and other identifiable intangible asset impairments. When we acquire a business, we record an asset called “goodwill” equal to the excess amount paid for the business, including liabilities assumed, over the fair value of the tangible and identifiable intangible assets of the business acquired. The Financial Accounting Standards Board (“FASB”) requires that all business combinations be accounted for using the acquisition method of accounting and that certain identifiable intangible assets acquired in a business combination be recognized as assets apart from goodwill. FASB Accounting Standard Codification (“ASC”) Topic 350, “Intangibles-Goodwill and Other” (“ASC 350”), provides that goodwill and other identifiable intangible assets that have indefinite useful lives not be amortized, but instead must be tested at least annually for impairment, and identifiable intangible assets that have finite useful lives should continue to be amortized over their useful lives and be tested for impairment whenever facts and circumstances indicate that the carrying values may not be fully recoverable. ASC 350 also provides specific guidance for testing goodwill and other non-amortized identifiable intangible assets for impairment, which we test annually each October 1. ASC 350 requires management to make certain estimates and assumptions to allocate goodwill to reporting units and to determine the fair value of reporting unit net assets and liabilities. Such fair value is determined using discounted estimated future cash flows. Our development of the present value of future cash flow projections is based upon assumptions and estimates by management from a review of our operating results, business plans, anticipated growth rates and margins and the weighted average cost of capital, among others. Much of the information used in assessing fair value is outside the control of management, such as interest rates, and these assumptions and estimates can change in future periods. There can be no assurance that our estimates and assumptions made for purposes of our goodwill and identifiable intangible asset impairment testing will prove to be accurate predictions of the future. If our assumptions regarding business plans or anticipated growth rates and/or margins are not achieved, or there is a rise in interest rates, we may be required to record goodwill and/or identifiable intangible asset impairment charges in future periods, whether in connection with our next annual impairment testing on October 1, 20142017 or earlier, if an indicator of an impairment is present prior to the quarter in which the annual goodwill impairment test is to be performed. It is not possible at this time to determine if any such additional impairment charge would result or, if it does, whether such a charge would be material to our results of operations.
The annual impairment review of our indefinite lived intangible assets for the year ended December 31, 2016 resulted in a $2.4 million non-cash impairment charge as a result of a change in the fair value of a subsidiary trade name associated with a prior acquisition reported within our United States mechanical construction and facilities services segment. We did not record an impairment of our goodwill or identifiable intangible assets for the year ended December 31, 2013.2016.
Amounts included in our backlog may not result in actual revenues or translate into profits. Many contracts are subject to cancellation or suspension on short notice at the discretion of the client, and the contracts in our backlog are subject to changes in the scope of services to be provided as well as adjustments to the costs relating to the contract. We have historically experienced variances in the components of backlog related to project delays or cancellations resulting from weather conditions, external market factors and economic factors beyond our control, and we may experience more delays or cancellations in the future. The risk of contracts in backlog being cancelled or suspended generally increases during periods of widespread slowdowns. Accordingly, there is no assurance that backlog will actually be realized. If our backlog fails to materialize, we could experience a reduction in revenues and a decline in profitability, which could result in a deterioration of our financial position and liquidity.
We account for the majority of our construction projects using the percentage-of-completion method of accounting; therefore, variations of actual results from our assumptions may reduce our profitability. We recognize revenues on construction contracts using the percentage-of-completion method of accounting in accordance with ASC Topic 605-35, “Revenue Recognition-Construction-Type and Production-Type Contracts”. See Application of Critical Accounting Policies in Item 7. Management'sManagement’s Discussion and Analysis of Financial Condition and Results of Operations. Under the percentage-of-completion method of accounting, we record revenue as work on the contract progresses. The cumulative amount of revenues recorded on a contract at a specified point in time is that percentage of total estimated revenues that costs incurred to date bear to estimated total costs. Accordingly, contract revenues and total cost estimates are reviewed and revised as the work progresses. Adjustments are reflected in contract revenues in the period when such estimates are revised. Estimates are based on management'smanagement’s reasonable assumptions and experience, but are only estimates. Variations of actual results from assumptions on an unusually large project or on a number

of average size projects could be material. We are also required to immediately recognize the full amount of the estimated loss on a contract when estimates indicate such a loss. Such adjustments and accrued losses could result in reduced profitability, which could negatively impact our cash flow from operations.

11


The loss of one or a few customers could have an adverse effect on us. A few clients have in the past and may in the future account for a significant portion of our revenues in any one year or over a period of several consecutive years. Although we have long-standing relationships with many of our significant clients, our clients may unilaterally reduce, fail to renew or terminate their contracts with us at any time. A loss of business from a significant client could have a material adverse effect on our business, financial position and results of operations.
We are increasingly dependent on sophisticated information technology systems; disruption, failure or cyber-security breaches of these systems could adversely affect our business and results of operations. We and our customers and third party providers rely on information technology systems and hardware and third party software to run critical accounting, project management and financial information systems. We rely upon security measures, products and services to secure our information technology systems and the confidential, proprietary and sensitive information they contain. However, our information technology systems and those of our customers and third-party providers could become subject to cyber-attacks, hacking, or other intrusions, failure or damage, which could result in operational disruptions or information misappropriation, such as theft of intellectual property or inappropriate disclosure of customer data or confidential or personal information. In addition, the proper functioning of these systems may be impacted by other causes and circumstances beyond our control, including the decision by software vendors to discontinue further development, integration or long-term software maintenance support for our information systems, or hardware interruption, damage or disruption as a result of power outages, natural disasters, or computer network failures. To the extent that our information technology systems, or those of our customers or third party providers, are disabled for a long period of time, certain key business processes could be interrupted. Any such operational disruptions and/or misappropriation or inappropriate disclosure of information could result in lost or reduced revenues, negative publicity, or business delays that could have a material adverse effect on our business, financial position and results of operations. We may also be required to expend significant resources to protect against the threat of such system disruptions and security breaches or to alleviate problems caused by such disruptions and breaches.
Natural disasters, terrorist attacks and other catastrophic events could disrupt our operations and services. Natural disasters, acts of terrorism and other catastrophic events, and the actions taken by the United States and/or other governments or actors in response to such events, may result in property damage, supply disruption or economic dislocations throughout the country. Although it is not possible to predict such events or their consequences, these events could increase the volatility of our financial results due to decreased demand and unforeseen costs, with partial or no corresponding compensation from clients.

Our failure to comply with anti-bribery statutes such as the Foreign Corrupt Practices Act and the U.K. Bribery Act of 2010 could result in fines, criminal penalties and other sanctions that could have an adverse effect on our business. The U.S. Foreign Corrupt Practices Act (the “FCPA”), the U.K. Bribery Act of 2010 (the “Bribery Act”) and similar anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments to foreign officials for the purpose of obtaining or retaining business. We conduct a modest amount of business in a few countries that have experienced corruption to some degree. If we were found to be liable for violations under the FCPA, the Bribery Act or similar anti-bribery laws, either due to our own acts or omissions or due to the acts or omissions of others, we could incur substantial legal expenses and suffer civil and criminal penalties or other sanctions, which could have a material adverse effect on our business, financial condition and results of operations, as well as our reputation.
Certain provisions of our corporate governance documents could make an acquisition of us, or a substantial interest in us, more difficult. The following provisions of our certificate of incorporation and bylaws,by-laws, as currently in effect, as well as Delaware law, could discourage potential proposals to acquire us, delay or prevent a change in control of us, or limit the price that investors may be willing to pay in the future for shares of our common stock:
our certificate of incorporation permits our board of directors to issue “blank check” preferred stock and to adopt amendments to our bylaws;by-laws;
our bylawsby-laws contain restrictions regarding the right of our stockholders to nominate directors and to submit proposals to be considered at stockholder meetings;
our certificate of incorporation and bylawsby-laws limit the right of our stockholders to call a special meeting of stockholders and to act by written consent; and
we are subject to provisions of Delaware law, which prohibit us from engaging in any of a broad range of business transactions with an “interested stockholder” for a period of three years following the date such stockholder becomes classified as an interested stockholder.

ITEM 3. LEGAL PROCEEDINGS
One of our subsidiaries, USM, Inc. ("USM"), doing business in California provides, among other things, janitorial services to its customers by having those services performed by independent janitorial companies. USM and one of its customers, which owns retail stores (the “Customer”), are co-defendants in a federal class action lawsuit brought by employees of two of USM’s California local janitorial contractors. The action captioned Federico Vilchiz Vasquez, Jesus Vilchiz Vasquez, Francisco Domingo Claudio, for themselves and all others similarly situated vs. USM, Inc. dba USM Services, Inc., a Pennsylvania Corporation, et al., was commenced on September 5, 2013 in a Superior Court of California and was removed by USM on November 22, 2013 to the United States District Court for the Northern District of California. The employees allege in their complaint, among other things, that USM and the Customer violated a California statute that prohibits USM from entering into a contract with a janitorial contractor when it knows or should know that the contract does not include funds sufficient to allow the janitorial contractor to comply with all local, state and federal laws or regulations governing the labor or services to be provided. The employees have asserted that the amounts USM pays to its janitorial contractors are insufficient to allow those janitorial contractors to meet their obligations regarding, among other things, wages due for all hours their employees worked, minimum wages and overtime pay. These employees seek to represent not only themselves, but also all other individuals who provided janitorial services at the Customer’s stores in California during the relevant four year time period. We do not believe USM or the Customer has violated the California statute or that the employees may bring the action as a class action on behalf of other employees of janitorial companies with whom USM contracted for the provision of janitorial services to the Customer. However, if the pending lawsuit is certified as a class action and USM is found to have violated the California statute, USM might have to pay significant damages and might be subject to similar lawsuits regarding the provision of janitorial services to its other customers in California. The plaintiffs seek a declaratory judgment that USM has violated the California statute, monetary damages, including all unpaid wages and thereon, restitution for unpaid wages, and an award of attorney fees and costs.
We are involved in several other proceedings in which damages and claims have been asserted against us. Other potential claims may exist that have not yet been asserted against us. We believe that we have a number of valid defenses to such proceedings and claims and intend to vigorously defend ourselves. We do not believe that any such matters will have a material adverse effect on our financial position, results of operations or liquidity. Litigation is subject to many uncertainties and the outcome of litigation is not predictable with assurance. It is possible that some litigation matters for which reserves have not been established could be decided unfavorably to us, and that any such unfavorable decisions could have a material adverse effect on our financial position, results of operations or liquidity. See Note 15 - Commitments and Contingencies of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data for a discussion regarding certain legal proceedings.

Dividends. We have paid quarterly dividends since October 25, 2011. During 2012, we paid a regular quarterly dividend of $0.05 per common share, and on December 7, 2012, our Board of Directors declared a special dividend of $0.25 per share, payable in December 2012, and announced its intention to increase the regular quarterly dividend to $0.06 per share. In addition, at the December 7, 2012 meeting of our Board of Directors, the regular quarterly dividend that would have been paid in January 2013 was declared, its amount increased to $0.06 per share and its payment date accelerated to December 28, 2012.

ITEM 7. MANAGEMENT'SMANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
We are one of the largest electrical and mechanical construction and facilities services firms in the United States. In addition, we provide a number of building services and industrial services. Our services are provided to a broad range of commercial, industrial, utility and institutional customers through approximately 7075 operating subsidiaries and joint venture entities. We had conducted businessOur offices are located in Canada through an indirect wholly owned subsidiary. We sold our Canadian subsidiary in August 2011.
During the third quarter of 2013, we completed the acquisition of RepconStrickland, Inc. (“RSI”), a leading provider of turnaround and specialty services to the North American refinery and petrochemical markets. In connection with the acquisition of RSI and to reflect changes in our internal reporting structure and the information used by management to make operating decisions and assess performance, we created a new segment that includes RSI and certain businesses that had been part of our United States facilities services segment. The new segment is called the United States industrial services segment and the segment formerly named the United States facilities services segment has been renamed the United States building services segment.
Our reportable segments have been restated in all periods presented to reflect the changes in our segments referred to above. The segment formally named the United Kingdom construction and facilities services segment has been renamed the United Kingdom construction and building services segment. In addition, the results of operations for all periods presented reflect: (a) discontinued operations accounting due to the disposition in August 2011 of our Canadian subsidiary and (b) certain reclassifications of prior period amounts from our United States building services segment to our United States mechanical construction and facilities services segment due to changes in our internal reporting structure.

During 2013, we made two strategic decisions to position ourselves for long-term growth and improved profitability. We completed the acquisition of RSI during the third quarter of 2013. This acquisition will expand and further strengthen our service offerings to new and existing customers and enhance our position within the industrial services and energy market sectors. In addition, due to recurring losses over the last several years from the construction operations of our United Kingdom construction and building services segment and our negative assessment of construction market conditions in the United Kingdom for the foreseeable future, we announced our decision to withdraw from the construction market in the United Kingdom.
Although revenues for 2013 slightly increased compared
Impact of Acquisitions
In order to 2012,provide a more meaningful period-over-period discussion of our operating incomeresults, we may discuss amounts generated or incurred (revenues, gross profit, selling, general and administrative expenses and operating margin (operating income as a percentage of revenues) decreased in 2013 compared to 2012. The increase in 2013 revenues compared to 2012 was primarily attributable to $133.3 million in revenuesincome) from companies acquired. The amounts discussed reflect the acquired in 2013, which are reported in our United States industrial services segment and our United States mechanical construction and facilities services segment. Excluding the impact of these acquisitions, most of our segments reported lower revenues in 2013, with the largest decline in revenues from our United Kingdom construction and building services segment. The decrease in 2013 revenues within the United Kingdom construction and building services segment is due to our decision earlier this year to withdraw from the United Kingdom construction market. These decreases were partially offset by higher revenues from our United States electrical construction and facilities services segment.
Both operating income and operating margin in 2013 were below that of 2012 due to: (a) declines in operating income and operating margin from our United States mechanical construction and facilities services segment, primarily as a result of poor performance by one of our subsidiaries at two projects located in the southeastern United States (resulting in aggregate losses of approximately $24.5 million) and (b) operating losses and restructuring expenses of $30.1 million related to the construction operations reported in our United Kingdom construction and building services segment. Offsetting this unfavorable performance in 2013 were improvedcompanies’ operating results in our United States building services segment. Companies acquiredthe current reported period only for the time period these entities were not owned by EMCOR in 2013, which arethe comparable prior reported in our United States industrial segment and our United States mechanical construction and facilities services segment,period.

contributed $2.0 million to operating income, net of $5.8 million of amortization expense associated with identifiable intangible assets.
As previously discussed, we completed the acquisition of RSI during 2013, and its results have been included in our United States industrial services segment since its acquisition. In addition, we completed two other acquisitions during 2013, and their results have been included in our United States mechanical construction and facilities services segment. All of these businesses expand our service capabilities into new technical areas.
Operating Segments
Our reportable segments have been restated in all periods presented to reflect the changes in our segments referred to above. The segment formally named the United Kingdom construction and facilities services segment has been renamed the United Kingdom construction and building services segment. In addition, the results of operations for all periods presented reflect: (a) discontinued operations accounting due to the disposition in August 2011 of our Canadian subsidiary and (b) certain reclassifications of prior period amounts from our United States building services segment to our United States mechanical construction and facilities services segment due to changes in our internal reporting structure.
We have the following reportable segments which provide services associated with the design, integration, installation, start-up, operation and maintenance of various systems: (a) United States electrical construction and facilities services (involving systems for electrical power transmission and distribution; premises electrical and lighting systems; process instrumentation in the refining, chemical process, food process and mining industries; low-voltage systems, such as fire alarm, security and process control; voice and data communication; roadway and transit lighting; and fiber optic lines); (b) United States mechanical construction and facilities services (involving systems for heating, ventilation, air conditioning, refrigeration and clean-room process ventilation; fire protection; plumbing, process and high-purity piping; controls and filtration; water and wastewater treatment; central plant heating and cooling; cranes and rigging; millwrighting; and steel fabrication, erection and welding); (c) United States building services; (d) United States industrial services; and (e) United Kingdom construction and building services. The segment “United States building services” and “United Kingdom building services” segments principally consistsconsist of those operations which provide a portfolio of services needed to support the operation and maintenance of customers'customers’ facilities, (commercialincluding commercial and government site-based operations and maintenance; facility maintenance and services, including reception, security and catering services; outage services to utilities and industrial plants; military base operations support services; mobile maintenance and services; floor care and janitorial services; landscaping, lot sweeping and snow removal; facilities management; vendor management; call center services; installation and support for building systems; program development, management and maintenance for energy systems; technical consulting and diagnostic services; infrastructure and building projects for federal, state and local governmental agencies and bodies; and small modification and retrofit projects; and retrofit projects, to comply with clean air laws), which services are not generally related to customers'customers’ construction programs. The segment "United“United States industrial services"services” segment principally consists of those operations which provide industrial maintenance and services, mainlyincluding those for refineries and petrochemical plants, including on-site repairs, maintenance and service of heat exchangers, towers, vessels and piping; design, manufacturing, repair and hydro blast cleaning of shell and tube heat exchangers and related equipment; refinery turnaround planning and engineering services; specialty welding services; overhaul and maintenance of critical process units in refineries and petrochemical plants; and specialty technical services for refineries and petrochemical plants.
We completed the acquisition of Ardent Services, L.L.C. and Rabalais Constructors, LLC (collectively, “Ardent”) during 2016. This acquisition has been included in our United States electrical construction and facilities services segment. Ardent provides electrical and instrumentation services to the petrochemical and energy infrastructure market in North America, and this acquisition further strengthens our position in electrical construction and services and broadens our capabilities across the industrial and energy sectors, especially in the Gulf Coast, Midwest and Western regions of the United States. Additionally during 2016, we acquired another company for an immaterial amount. This company provides mobile mechanical services within the Southeastern region of the United States, and its results have been included in our United States building services segment.
We acquired three companies in 2015, each for an immaterial amount. Two of the companies acquired primarily provide mechanical construction services, and their results of operations have been included in our United States mechanical construction and facilities services segment. The results of operations for the other company acquired have been included in our United Kingdom construction andStates building services segment performs electrical construction, mechanical construction and were de minimus.

2013 versus 2012
Revenues
As described in more detail below, revenues for 2013 were $6.4 billion compared to $6.3 billion for 2012.services segment. The increase in revenues for 20132016 was primarily attributable to: (a) incremental revenuesour domestic construction segments, due to increased activity within the majority of approximately $133.3 million generated bythe market sectors in which we operate, (b) our United States industrial services segment, as a result of increased demand for specialty services offerings within our field services operations, and (c) our United States building services segment, primarily due to higher volume within our mobile mechanical services operation. In addition, companies acquired in 2013,2016 and 2015, which are reported in our United States electrical construction and facilities services segment, our United States mechanical construction and facilities services segment and our United States building services segment, generated incremental revenues of $250.8 million for the year ended December 31, 2016.
The increase in operating income was attributable to improved operating performance within all of our reportable segments, except for our United States mechanical construction and facilities services segment. Our operating income was favorably impacted by: (a) our United States industrial services segment, as a result of large project activity within our field services operations, (b) our United States electrical construction and facilities services segment, primarily attributable to an increase in gross profit from commercial, transportation and hospitality construction projects, and (c) our United States building services segment, as a result of increased gross profit within our mobile mechanical services operations. In addition, companies acquired in 2016 and 2015 generated incremental operating income of $14.3 million, net of $4.1 million of amortization expense associated with identifiable intangible assets. Our 2016 operating results were negatively impacted by: (a) $27.9 million of aggregate losses incurred on two construction projects reported within our United States mechanical construction and facilities services segment and (b) higher revenues from$19.4 million of losses incurred on a transportation construction project in the Northeastern region of the United States reported within our United States electrical construction and facilities services segment, partially offset by lower revenues fromsegment. These three projects were substantially complete at the end of 2016, and we will seek recovery for our United Kingdomlosses. Corporate administration operating loss increased as a result of: (a) an increase in employment costs, such as incentive compensation and salaries, (b) $3.8 million of transaction costs associated with the acquisition of Ardent in April 2016, (c) an increase in certain non-income related taxes and (d) an increase in software licensing costs and legal costs.
Our operating margin (operating income as a percentage of revenues) was 4.1% and 4.3% for 2016 and 2015, respectively. The decrease in operating margin was attributable to the cumulative impact of the three construction and building services segment and our United States mechanical construction and facilities services segment, excluding the effectprojects referenced above, which incurred losses of acquisitions in 2013. We continue to be disciplined by only accepting work$47.3 million. These three projects resulted in a very competitive marketplace that we believe can be performed at reasonable margins.0.7% negative impact on the Company’s operating margin for 2016.

As described in more detail below, revenues for 2016 were $7.6 billion compared to $6.7 billion for 2015.
Revenues of our United States electrical construction and facilities services segment were $1,345.8$1,704.4 million for the year ended December 31, 20132016 compared to revenues of $1,211.7$1,367.1 million for the year ended December 31, 2012. This2015. Excluding the acquisition of Ardent, the increase in revenues was primarily attributable to higher levels of workan increase in revenues from commercial, institutional, manufacturingtransportation and transportationhospitality construction projects, primarily in the Southern California and New York City markets, partially offset by a decrease in revenues from watermanufacturing and wastewaterhealthcare construction projects. The results for the year ended December 31, 2016 included $158.5 million of revenues generated by Ardent.
Our United States mechanical construction and facilities services segment revenues for the year ended December 31, 20132016 were $2,329.8$2,661.8 million, a $56.7$349.0 million decreaseincrease compared to revenues of $2,386.5$2,312.8 million for the year ended December 31, 2012. This decrease2015. The increase in revenues was primarily attributable to declines in revenues from institutional, healthcare and water and wastewater construction projects. In addition, this segment’s results for 2012 included approximately $224.0 million of revenues attributable to a large manufacturing project compared to $23.1 million of revenues recognized on the same project in 2013. These decreases were partially offset by an increase in revenues from other manufacturing construction projects andactivity within the majority of the market sectors in which we operate. The results for the year ended December 31, 2016 included $45.9 million of incremental revenues of approximately $9.7 million generated by companies acquired in 2013.2015.
Revenues of our United States building services segment were $1,795.0$1,791.8 million and $1,807.9$1,739.3 million in 20132016 and 2012,2015, respectively. This decreaseThe increase in revenues was primarily attributable to increased revenues from: (a) our mobile mechanical services operations as a reductionresult of greater project, service and controls activities and (b) our energy services operations, as a result of an increase in large project activity. The results for the year ended December 31, 2016 included $46.4 million of revenues from our government site-based services and our commercial site-based services,generated by a company acquired in 2016. These increases were partially offset by an increase in revenues from our energy services and our mobile mechanical services. Thea decrease in revenues from our government site-based services was primarily due to a reduction in discretionary government project spending and the loss in 2012 of certain maintenance contracts, and the decrease in our commercial site-based services was primarily due tooperations as a result of the terminationloss of certain unprofitable contracts. The increasecontracts not renewed pursuant to rebid, and in revenues fromthe case of our energygovernment site-based services was due to large project work, andoperations, the increase in revenues from our mobile mechanical services was due to higher project and services revenues.result of certain scope reductions within their current contract portfolio.
Revenues of our United States industrial services segment for the year ended December 31, 20132016 increased by $117.6$145.2 million compared to the year ended December 31, 2012. This2015. The increase in revenues was primarily due to increased demand for specialty services offerings within our field services operations, including large project activity. The increase in revenues from our field services operations was partially offset by a decrease in revenues from our shop services operations due to lower demand for new heat exchangers as a result of the $123.6 millioncontinued curtailment in capital spending by many large integrated oil companies. In addition, revenues for the first half of incremental revenues generated2015 were negatively impacted by RSI. Excludinga nationwide strike by union employees of certain major oil refineries which led to the resultscancellation of this acquisition, revenues decreased fromcertain turnaround and maintenance services work performed compared to revenues in 2012. The results in 2012 benefited from the favorable impact of three large non-recurring turnaround and repair projects.

Our United Kingdom construction and building services segment revenues were $427.2$326.3 million in 20132016 compared to $538.8$377.5 million in 2012.2015. This decrease insegment’s revenues was attributable to a reduction in our construction operations in the United Kingdom, as a consequence of both weak market conditions and our decision earlier this year to withdraw from the construction market in the United Kingdom. This decision was based on recurring losses over the last several years in the construction operations of our United Kingdom segment and our negative assessment of construction market conditions in the United Kingdomdecreased by $41.0 million for the foreseeable future. This decrease in revenues was also attributable to: (a) lower revenues within this segment’s building services business as a result of reduced activity in the commercial and transportation markets and (b) a decrease of $6.4 million relatingyear ended December 31, 2016 related to the effect of unfavorable exchange rates for the British pound versus the United States dollar.dollar resulting, in part, from the decision by the United Kingdom to exit the European Union. In addition, the decrease in this segment’s revenues was partially attributable to a decrease in small project activity within the institutional market sector.

Our backlog at December 31, 20132016 was $3.36$3.90 billion compared to $3.37$3.77 billion at December 31, 2012.2015. This slight decreaseincrease in backlog was primarily attributable to lower backlog within most of our segments, partially offset by an increase in backlog from all of our reportable segments, except for our United States electrical constructionbuilding services segment and facilitiesour United States industrial services segment. Backlog increases with awards of new contracts and decreases as we perform work on existing contracts. Backlog is not a term recognized under United States generally accepted accounting principles; however, it is a common measurement used in our industry. We include a project within our backlog at such time as a contract is awarded.awarded and agreement on contract terms has been reached. Backlog includes unrecognized revenues to be realized from uncompleted construction contracts plus unrecognized revenues expected to be realized over the remaining term of services contracts. However, we do not include in backlog contracts for which we are paid on a time and material basis and a fixed amount cannot be determined, and if the remaining term of a services contract exceeds 12 months, the unrecognized revenues attributable to such contract included in backlog are limited to only the next 12 months of revenues provided for in the initial contract award. Our backlog also includes amounts related to services contracts for which a fixed price contract value is not assigned; however,assigned when a reasonable estimate of total revenues can be made from budgeted amounts agreed to with our customer.customers. Our backlog is comprised of: (a) original contract amounts, (b) change orders for which we have received written confirmations from our customers, (c) pending change orders for which we expect to receive confirmations in the ordinary course of business and (d) claim amounts that we have made against customers for which we have determined we have a legal basis under existing contractual arrangements and as to which we consider collectionrecovery to be probable. ClaimSuch claim amounts recorded were immaterial for all periods presented. Our backlog does not include anticipated revenues from unconsolidated joint ventures or variable interest entities and anticipated revenues from pass-through costs on contracts for which we are acting in the capacity of an agent and which are reported on the net basis. We believe our backlog is firm, although many contracts are subject to cancellation at the election of our customers. Historically, cancellations have not had a material adverse effect on us.

gross profit from a company acquired in 2013, (b) companies acquired in 2013 reported within our United States industrial services segment and our United States mechanical construction and facilities services segment, which contributed approximately $23.0 million to gross profit, and (c) the receipt of an insurance recovery of approximately $2.6 million during the first quarter of 2013 associated with a previously disposed of operation, which is classified as a component of "Cost of sales" on the Consolidated Statements of Operations. Gross profit was negatively impacted by asegment. The decrease in gross profit from: (a) our United States mechanicalmargin was attributable to the cumulative impact of the three construction and facilities services segment, as a consequence of aggregateprojectsreferenced above, which incurred losses of approximately $24.5 million from one of our subsidiaries at two$47.3 million. These three projects locatedresulted in a 0.8% negative impact on the southeastern United States and (b) our United Kingdom construction and building services segment.
OurCompany’s gross profit margin was 12.7% for both 2013 and 2012. Gross profit margin for the year ended December 31, 2013 increased in our United States building services segment and our United States industrial services segment primarily due to improved project execution and the termination of certain unprofitable contracts. Gross profit margin decreased in all our other reportable segments. Gross profit margin declined in our United States mechanical construction and facilities services segment and our United Kingdom construction and building services segment due to construction contract losses, resulting in a 0.8% impact on consolidated gross profit margin. Gross profit margin in 2013 in our United States electrical construction and facilities services segment declined as 2012 gross profit margin had benefited from the resolution of construction claims, resulting in approximately $9.5 million of gross profit.2016.

Our selling, general and administrative expenses for the year ended December 31, 20132016 were $591.1$725.5 million, a $34.8$69.0 million increase compared to selling, general and administrative expenses of $556.2$656.6 million for the year ended December 31, 2012.2015. Selling, general and administrative expenses as a percentage of revenues were 9.2%9.6% and 8.8%9.8% for the years ended December 31, 20132016 and 2012,2015, respectively. ThisThe increase in selling, general and administrative expenses primarily resulted from: (a) $21.0for the year ended December 31, 2016 included $30.3 million of incremental expenses directly related to companies acquired in 2013,2016 and 2015, including amortization expense attributable to identifiable intangible assets of $5.8 million, (b) $6.1$3.4 million. Additionally, selling, general and administrative expenses included $3.8 million of transaction costs associated with the acquisition of RSIArdent in April 2016. Excluding the impact of acquisitions, the increase in selling, general and (c)administrative expenses was primarily due to higher legalemployee related costs such as incentive compensation, salaries and other professional fees. In addition, we recognized commissions. Increased incentive compensation was principally due to higher annual operating results than in the same prior year period, which resulted in increased accrualsfor the years ended December 31, 2013 and 2012, respectively, $6.8 million and $6.4 millioncertain of incomeour incentive compensation plans. The increase in salaries was attributable to an increase in headcount due to higher revenues than in the reversalsame prior year period, as well as cost of contingent consideration accruals relatingliving adjustments and merit pay increases. The increase in selling, general and administrative expenses was also due to acquisitions made priorincreases in the provision for doubtful accounts, information technology costs and certain non-income related taxes. The decrease in SG&A margin was partially attributable to 2013.an increase in revenues without commensurate increases in our overhead cost structure.

These projects resulted in a 0.7% negative impact on the Company’s operating margin for 2016.
Operating income of our United States electrical construction and facilities services segment for the year ended December 31, 20132016 was $98.1$101.8 million compared to operating income of $100.7$82.2 million for the year ended December 31, 2012.2015. The decreaseincrease in operating income was partially attributable to an increase in gross profit from commercial, transportation and hospitality construction contracts. The increase in operating income was also partially attributable to the acquisition of Ardent, which contributed operating income of $8.1 million, net of $2.1 million of amortization expense associated with identifiable intangible assets, for the year ended December 31, 20132016. Operating income was primarilynegatively impacted by a transportation construction project in the Northeastern region of the United States, which incurred losses of $19.4 million as a result of a reduction in gross profit from water and wastewater construction projects, partially offset by an increase in gross profitproductivity issues attributable to commercial, institutional and manufacturing construction projects.

These projects were substantially complete at the end of 2016, and we will seek recovery for our losses. Additionally, the results for 2015 included aggregate lossesrevenues of approximately $24.5$12.1 million from onerecognized as a result of our subsidiaries at two projectsthe settlement of a claim on an institutional project located in the southeastern United States, resulting in a 1.1% impact on this segment's operating margin. One of these projects was in progress at the time of acquisitionSoutheastern region of the subsidiary and will be completedUnited States. The decrease in 2014. The other project, which was contracted for post-acquisition, has incurred losses principally due to poor performance by one of our subcontractors on the project which we have replaced and is substantially complete. In addition to the effect of these two projects, operating income in 2012 was favorably impactedpartially offset by an increase in gross profit from commercial and hospitality construction projects. Additionally, the results for the year ended December 31, 2016 included the receipt of $24.1$2.0 million recognized onfrom the former owner of a large manufacturing project.company we had previously acquired as a result of a settlement of a claim by us under the acquisition agreement. Companies acquired in 20132015 generated incremental operating lossesincome of approximately $1.0$3.4 million, includingnet of $0.6 million of amortization expense of $0.1 million attributable toassociated with identifiable intangible assets, for the year ended December 31, 2013. The decrease in operating income for the year ended December 31, 2013 was partially offset by higher gross profit from commercial construction projects and a decrease in selling, general and administrative expenses primarily due to lower incentive compensation expense. In addition, we recognized for the years ended December 31, 2013 and 2012, respectively, $6.7 million and $5.4 million of income attributable to the reversal of contingent consideration accruals relating to acquisitions made prior to 2013.2016. The decrease in operating margin was primarily attributable to the cumulative impact of the two projects referenced above, which resulted in a reduction in gross profit margin.1.2% negative impact on this segment’s operating margin for 2016.

Operating income of our United States building services segment was $67.2$75.8 million and $43.3$70.5 million in 20132016 and 2012,2015, respectively. The increase in operating income was primarily attributable to an increase in gross profit from this segment's: (a) commercial site-basedproject, service and controls activities within our mobile mechanical services partiallyoperations. Additionally, a company acquired during the second quarter of 2016, within our mobile mechanical services operations, generated operating income of $2.8 million, net of $1.4 million of amortization expense associated with identifiable intangible assets, for the year ended December 31, 2016. The increase in operating margin for the year ended December 31, 2016 was attributable to an increase in revenues from snow removal and the termination of certain unprofitable contracts, (b) mobile mechanical services, partially as a result of greater project and services revenues and improved job execution, and (c) energy services, as a result of increased gross profits on large project work. The increase in operating income

This2015. The increase in operating income was primarily attributable to an increase in gross profit from project activity within the commercial market sector, partially as a result of several contract awards won in 2015, offset in part by a decrease of $1.5 million relating to the effect of unfavorable resultexchange rates for the British pound versus the United States dollar. The increase in operating margin was due to: (a)attributable to an increase in gross profit margin.
Our corporate administration operating loss of $19.0was $88.7 million for 2016 compared to $71.6 million in 2015. The increase in expenses for the year ended December 31, 2013 from its construction operations due to lower volume and project write-downs attributable to both weak market conditions and our decision earlier this year to withdraw from the construction market in the United Kingdom and (b) lower volume from its building services operations as a result of reduced project activity, partially offset by lower selling general and administrative expenses predominantly as a result of lower employee related costs. Operating margin in this segment decreased for 2013 compared to 2012 due to operating losses from its construction operations.
Our corporate administration expenses were $69.9 million for 2013 compared to $63.5 million in 2012. The increase in expenses2016 was primarily due to: (a) an increase in employment costs, such as incentive compensation, primarily due to $6.1higher annual operating results in 2016 compared to the same prior year period, (b) an increase in certain non-income related taxes, (c) an increase in software licensing costs and (d) an increase in legal costs. Additionally, operating results for the year ended December 31, 2016 included $3.8 million of transaction costs associated with the RSI acquisition.

Our operating results for 2015 were negatively impacted by: (a) our United States electrical construction and facilities services segment, (b) our United States industrial services segment and (c) our United Kingdom building services segment. Decreases in both operating income and operating margin within our United States electrical construction and facilities services segment were partially attributable to approximately $10.1 million of losses incurred on several transportation projects. Decreases in both operating income and operating margin within our United States industrial services segment were primarily due to: (a) the negative impact of a nationwide strike by union employees of certain major oil refineries in the first half of 2015, which led to both deferrals and losses of certain turnaround projects that generate relatively high gross profit margins, and (b) a decrease in the billing rates and related gross profit margins within our industrial shop services operations due to competitive market conditions resulting from decreased demand for new heat exchangers as a result of volatility in crude oil prices that led to a curtailment in capital spending.
Two of the companies acquired in 2015, which are reported in our United States mechanical construction and facilities services segment, generated incremental revenues of $12.5 million and less than $0.1 million of operating income, net of $0.3 million of amortization expense associated with identifiable intangible assets. The results of operations for the third company acquired in 2015, which are reported in our United States building services segment, were de minimis.

As described in more detail below, revenues for 2015 were $6.7 billion compared to $6.4 billion for 2014. The increase in revenues for 2015 was primarily attributable to: (a) increased revenues from both of our domestic construction segments, (b) increased demand for our industrial field services within our United States industrial services segment and (c) increased revenues from our mobile mechanical services operations within our United States building services segment. AnRevenues increased within our United States industrial services segment despite a nationwide strike by union employees of certain major oil refineries that negatively impacted the first half of 2015.
Revenues of our United States electrical construction and facilities services segment were $1,367.1 million for the year ended December 31, 2015 compared to revenues of $1,312.0 million for the year ended December 31, 2014. The increase in revenues atwas primarily attributable to an increase in revenues from commercial, healthcare and manufacturing construction projects, partially offset by a decrease in revenues from institutional construction projects.
Our United States mechanical construction and facilities services segment revenues for the year ended December 31, 2015 were $2,312.8 million, a $111.6 million increase compared to revenues of $2,201.2 million for the year ended December 31, 2014. The increase in revenues was primarily attributable to an increase in revenues from commercial and institutional construction projects, partially offset by a decline in revenues from manufacturing, water and wastewater and transportation construction projects. The results for the year ended December 31, 2015 included $12.5 million of revenues generated by companies acquired in 2015.
Revenues of our United States building services segment were $1,739.3 million and $1,721.3 million in 2015 and 2014, respectively. The increase in revenues was primarily attributable to increased revenues from: (a) our mobile mechanical services operations, in part due to significant activity in the California and New England regions and increased project and retrofit activities, and (b) our energy services operations. These increases were partially offset by decreased revenues from: (a) our government site-based services operations as a result of the completion in 2014 of twolarge long-term site-based joint venture projects not renewed pursuant to rebid and (b) our commercial site-based services operations as a result of: (i) a decline in add-on project activities, (ii) a decrease in revenues from its snow removal activities, as a result of less snowfall in geographical areas in which many of our contracts are billed on a per snow event basis, and (iii) a decrease in revenues from supplier management contracts.
Revenues of our United States industrial services segment for the year ended December 31, 2015 increased by $82.1 million compared to the year ended December 31, 2014. The increase in revenues was primarily due to large capital and maintenance project activity within our industrial field services operations. Revenues increased within this segment despite a nationwide strike by union employees of certain major oil refineries that negatively impacted the first half of 2015.
Our United Kingdom operationsbuilding services segment revenues were $377.5 million in 2015 compared to $350.4 million in 2014. The increase in revenues was due to an increase in activity in the commercial market attributable to several new contract awards as well as increased work under existing contracts. The increase in revenues was partially offset by a decrease of $6.5$29.2 million relating to the effect of unfavorable exchange rates for the British pound versus the United States dollar.

Revenues of our United States electrical construction and facilities services segment were $1,211.7 million for the year ended December 31, 2012 compared to revenues of $1,155.1 million for the year ended December 31, 2011. This increase in revenues was primarily attributable to higher levels of work from manufacturing, institutional and commercial construction projects, partially offset by a decrease in revenues from healthcare, transportation and hospitality construction projects.
Our United States mechanical construction and facilities services segment revenues for the year ended December 31, 2012 were $2,386.5 million, a $377.4 million increase compared to revenues of $2,009.1 million for the year ended December 31, 2011. This increase in revenues was primarily attributable to: (a) an increase in revenues from manufacturing, commercial and transportation construction projects, excluding the effect of acquisitions made in 2012 and 2011, and (b) incremental revenues of approximately $128.6 million generated by companies acquired in 2012 and 2011, partially offset by a decrease in revenues from healthcare, institutional, hospitality and water and wastewater construction projects.
Revenues of our United States building services segment were $1,807.9 million and $1,603.0 million in 2012 and 2011, respectively. This increase in revenues was primarily attributable to incremental revenues of approximately $175.3 million generated by companies acquired in 2011, which perform building maintenance services and mobile mechanical services, and from an increase in revenues at: (a) our commercial site-based operations, excluding the effect of the acquisition made in 2011, primarily the result of new project awards and (b) our government services operations, primarily due to new contract awards and organic growth in the medical building services portfolio. This increase was partially offset by a decrease in revenues from our energy services operations primarily as a result of the loss of a large contract at the end of 2011.
Revenues of our United States industrial services segment for the year ended December 31, 2012 increased by $84.4 million compared to the year ended December 31, 2011. This increase in revenues was primarily due to an increase in demand for our services in the refinery market and the favorable impact of three large non-recurring turnaround and repair service projects.
Our United Kingdom construction and building services segment revenues were $538.8 million in 2012 compared to $529.0 million in 2011. This increase in revenues was primarily attributable to growth in revenues in our building services business as a result of an expansion in scope of contract activity with our existing customers in the commercial and transportation markets, partially offset by a decrease in revenues from our United Kingdom construction business as a result of lower volume from institutional and healthcare construction projects and a decrease of $6.5 million relating to the effect of unfavorable exchange rates for the British pound versus the United States dollar.

Our backlog at December 31, 20122015 was $3.37$3.77 billion compared to $3.33$3.63 billion of backlog at December 31, 2011.2014. This slight increase in backlog excluding the effect of acquisitions, was primarily attributable to: (a)to an increase in contracts awarded for work in all of our domestic segments and (b) an increase of $27.7 million in backlog associated with a company acquired in 2012, which is included infrom our United States mechanical construction and facilities services segment. This increase wassegment and our United States building services segment, partially offset by lower backlog withinfrom our United Kingdom segment.other reportable segments.

The increase in gross profit was primarily attributable to: (a) companies acquired in 2012 and 2011 reported within our United States mechanical construction and facilities services segment and our United States building services segment, which contributed approximately $29.2 million to gross profit, net of amortization expense attributable to identifiable intangible assets of $0.2 million, (b) our United States industrial services segment, (c) our United States electrical construction and facilities services segment and (d) our United States mechanical construction and facilities services segment, excluding the gross profit from companies acquired in 2012 and 2011. These increases were partially offset by lower gross profit from our United Kingdom operations, whose construction business experienced several project write-downs. The increase in gross profit was also negatively impacted by changes in the exchange rates for the British pound versus the United States dollar.

Favorable variances in both gross profit and gross profit margin was primarily the result of lower gross profit margin at:within: (a) our United States mechanical construction and facilities services segment, primarilywhich included revenues of $12.1 million recognized as a result of the favorable resolution in 2011 of various uncertainties on projects and the settlement of a long outstanding construction claim on an institutional project located in the Southeastern region of the United States, and (b) our United States building services segment were partially attributable to theoffset by decreases in gross profit and gross profit margin dilutive impact of an acquisition in 2011, and (c)within our United Kingdom operations, as a result of the operating loss from its construction business. The decrease in gross profit margin in 2012 was partially offset by higher gross profit margin at our United States industrialbuilding services segment and our United States electrical construction and facilities services segment. Gross profit within our United States industrial services segment primarily asslightly increased; however, gross profit margin within this segment declined due to a result of: (a)decrease in the favorable resolution of a long outstanding construction claim on a waterbilling rates and wastewater construction project and (b) higherrelated gross profit margins within our industrial shop services operations due to competitive market conditions resulting from certain other construction projects,decreased demand for new heat exchangers as a result of claim settlements and better than anticipated project execution on other contracts.volatility in crude oil prices that led to a curtailment in capital spending.

Our selling, general and administrative expenses for the year ended December 31, 20122015 were $556.2$656.6 million, a $38.1$30.1 million increase compared to selling, general and administrative expenses of $518.1$626.5 million for the year ended December 31, 2011. This increase was primarily attributable to: (a) $26.9 million of incremental expenses directly related to companies acquired in 2012 and 2011, including amortization expense attributable to identifiable intangible assets of $4.9 million, and (b) higher employee related costs such as incentive compensation and employee benefits, partially as a result of improved results and share-based compensation costs, partially offset by a decrease in professional fees, as we had incurred $4.7 million of transaction costs associated with an acquisition made in 2011. In addition, we recognized for the years ended December 31, 2012 and 2011, respectively, $6.4 million and $2.8 million of income attributable to the reversal of contingent consideration accruals relating to acquisitions made prior to 2012.2014. Selling, general and administrative expenses as a percentage of revenues decreasedwere 9.8% for 2012 compared to 2011, primarily related to our ability to increase revenues at a greater rate than theboth 2015 and 2014. The increase in overheadselling, general and administrative expenses was due to higher employee related costs such as incentive compensation, salaries and medical insurance costs, as well as certain other costs including computer hardware and software expenses, partially offset by a decrease in legal costs. Increased incentive compensation was principally due to higher annual operating results within certain operations than in 2014, which resulted in increased accruals for their incentive compensation plans. The increase in salaries was attributable to an increase in headcount, commensurate with an increase in revenues, as well as cost of living adjustments and merit pay increases.

Restructuring expenses
Restructuring expenses primarily relating to employee severance obligations and/or the termination of leased facilities, were $0.1$0.8 million and $1.2 million for 20122015 and 2011,2014, respectively. The 20122015 restructuring expenses were primarily attributable to

Impairment loss on goodwill and identifiable intangible assets
In conjunction with our 2011 annualNo impairment test on October 1, 2011, we recognized a $3.8 million non-cash impairment charge related to customer relationships and trade names within the United States building services segment during the fourth quarter of 2011. This impairment primarily resulted from both lower forecasted revenues from, and lower operating margins at, specific companies within this segment.
Based upon our annual impairment testing as of October 1, 2012, no additional impairment of our goodwill or our identifiable intangible assets was recognized for the year ended December 31, 2012.2015. In conjunction with our 2014 annual impairment test on October 1, we recognized a $1.5 million non-cash impairment charge related to subsidiary trade names within the United States mechanical construction and facilities services segment and the United States building services segment. The 2014 impairment primarily resulted from lower forecasted revenues from two companies within these segments. Additionally, no impairment of our goodwill was recognized for the years ended December 31, 2015 and 2014.

The decrease in operating income of $84.6 million for the year ended December 31, 2011. This2015 was due to a decrease in gross profit from transportation, institutional and manufacturing construction projects and an increase in selling, general and administrative expenses due to higher employee related costs such as incentive compensation and salaries. The decrease in gross profit from transportation construction projects

included approximately $10.1 million of losses incurred on several projects due to productivity issues and delays. The increase in incentive compensation was principally due to higher annual operating results within certain operations than in 2014, which resulted in increased accruals for certain of our incentive compensation plans. The decrease in operating income primarily resulted fromwas partially offset by an increase in gross profit from: (a) water and wastewatercommercial construction projects, partially due to profits recognized on contracts in the Mid-Atlantic region, and (b) manufacturing and institutionalhealthcare construction projects. In addition, operating income in 2012 benefited from the favorable resolution of a construction claim on a healthcare project, as well as from a long outstanding construction claim on a water and wastewater construction project. This increase in operating income was partially offset by aThe decrease in gross profit attributable to: (a) hospitality construction projects and (b) smaller quick turn project work. Additionally, operating income in 2011 benefited from the favorable resolution of uncertainties on a hospitality construction project and from the favorable resolution of an institutional construction claim. Selling, general and administrative expenses increased for the year ended December 31, 2012, compared to 2011, principally due to higher employee related costs, primarily incentive compensation accruals as a result of improved results, and higher professional fees.

The increase in operating income was primarily due to higher operating income as a result of an increase in demand for our services in the refinery market and the favorable impact of three large non-recurring turnaround and repair service projects.
Our United Kingdom construction and building services segment operating income was $7.1 million in 2012 compared to $9.2 million in 2011. This decrease in operating income was primarily attributable to: (a) a decrease in gross profit from our industrial shop services operations due to: (i) a decrease in the billing rates and related gross profit margins due to an operating loss within our United Kingdom construction businesscompetitive market conditions resulting from decreased demand for new heat exchangers as a result of volatility in crude oil prices that led to a curtailment in capital spending and (ii) the mix of work, which included fewer repair projects than in 2014, that generate relatively high gross profit margins, (b) the negative impact of a nationwide strike by union employees of certain major oil refineries in the first half of 2015, which led to both deferrals and losses recognized on various hospitality, institutionalof certain turnaround projects that generate relatively high gross profit margins, and commercial construction projects(c) an increase in selling, general and administrative expenses due to higher employee related costs such as salaries and employee benefits, partially as a result of increased headcount. The decrease in operating income was partially offset by large capital and maintenance project activity within our industrial field services operations. The decrease in operating margin for the year ended December 31, 2015 was attributable to a decrease in gross profit margin.
Our United Kingdom building services segment’s operating income for the year ended December 31, 2015 was $11.6 million compared to operating income of $0.2$15.0 million for the year ended December 31, 2014. The decrease in operating income and operating margin was primarily attributable to the impact of $4.8 million of income recognized in the second quarter of 2014 as a result of a reduction in the estimate of certain accrued contract costs that were no longer expected to be incurred. The overall decrease in gross profit in this segment was partially offset by an increase in gross profit from both new contract awards and increased project activity within the commercial market sector. This segment recorded a decrease in operating income of $0.9 million relating to the effect of unfavorable exchange rates for the British pound versus the United States dollar. The decrease in operating income was partially offset by an increase in operating income from its building services business as a result of better performance on its commercial and institutional portfolio of contracts. The decrease in operating margin for 2012 was brought about by a combination of lower gross profit margins, partially offset by a decrease in selling, general and administrative expenses as a percentage of revenues.

Our consolidated cash balance increased by approximately $54.8 million from $432.1 million at December 31, 2014 to $486.8 million at December 31, 2015. Net cash provided by operating activities for 2015 was $266.7 million compared to $246.7 million of net cash provided by operating activities for 2014. The increase in cash provided by operating activities was primarily attributabledue to improved cash flows from: (a) net over-billings of $70.7 million, (b) accounts payable of $50.6 million and (c) other working capital changes of $40.5 million, partially offset by a reduction in cash flows from accounts receivable of $142.7 million. Net cash used in investing activities was $59.8 million for 2015 compared to net cash used in investing activities of $21.7 million for 2014. The increase in cash used in investing activities was primarily due to payments to acquire businesses in 2015. Net cash used in financing activities for 2015 decreased by approximately $80.5 million compared to 2014. The decrease in net cash used in financing activities was primarily due to a decrease in funds used for the paymentrepurchase of dividends.common stock.

(1)On November 25, 2013,August 3, 2016, we entered into a $1.1 billion credit agreement (the "2013 Credit Agreement"), which is comprised of a $750.0$900.0 million revolving credit facility (the “2013“2016 Revolving Credit Facility”) and a $350.0$400.0 million term loan (the "Term Loan"“2016 Term Loan”) (collectively referred to as the “2016 Credit Agreement”). The proceeds of the 2016 Term Loan were used to repay amounts drawn under our previousprior credit agreement. As of December 31, 2013,2016, the amount outstanding under the 2016 Term Loan was $350.0$300.0 million. As of December 31, 2016, there were borrowings outstanding of $125.0 million under the 2016 Revolving Credit Facility.
(2)Represents open purchase orders for material and subcontracting costs related to construction and service contracts. These purchase orders are not reflected in our consolidated balance sheetsthe Consolidated Balance Sheets and should not impact future cash flows, as amounts should be recovered through customer billings.
(3)Represents primarily insurance related liabilities, and liabilities for deferred income taxes, incentive compensation and earn-out arrangements,deferred compensation, classified as other long-term liabilities in the consolidated balance sheets.Consolidated Balance Sheets. Cash payments for insurance and deferred compensation related liabilities may be payable beyond three years, but it is not practical to estimate these payments.payments; therefore, these liabilities are reflected in the 1-3 years payment period. We provide funding to our post retirement plans based on at least the minimum funding required by applicable regulations. In determining the minimum required funding, we utilize current actuarial assumptions and exchange rates to forecast estimates of amounts that may be payable for up to five years in the future. In our judgment, minimum funding estimates beyond a five year time horizon cannot be reliably estimated, and therefore, have not been included in the table.
(4)Includes $0.5 million of accrued interest.

Until August 3, 2016, we had a credit agreement dated as of November 25, 2013 we had a revolving credit agreement (the “2011(as amended, the “2013 Credit Agreement”) as amended,, which provided for a revolving credit facility of $750.0 million. The 2011 Credit Agreement was effective November 21, 2011. Effective November 25, 2013, we amended and restated the 2011 Credit Agreement with a $1.1 billion credit agreement (the "2013 Credit Agreement"), which is comprised of a $750.0 million revolving credit facility (the “2013 Revolving Credit Facility”) and a term loan of $350.0 million (the “2013 Term Loan”). On August 3, 2016, we amended and restated the 2013 Credit Agreement to provide for a $900.0 million revolving credit facility (the “2016 Revolving Credit Facility”) and a $400.0 million term loan (the "Term Loan"“2016 Term Loan”). (collectively referred to as the “2016 Credit Agreement”) expiring August 3, 2021. The proceeds of the 2016 Term Loan were used to repay amounts drawn under the 20112013 Term Loan, as well as a portion of the outstanding balance under the 2013 Revolving Credit Agreement. Both facilities expire on November 25, 2018.Facility. We may increase the 20132016 Revolving Credit Facility to $1.05$1.3 billion if additional lenders are identified and/or existing lenders are willing to increase their current commitments; and wecommitments. We may allocate up to $250.0$300.0 million of available borrowingscapacity under the 20132016 Revolving Credit Facility to letters of credit for our account ofor for the account of any of our subsidiaries. The 2013 RevolvingObligations under the 2016 Credit Facility and the Term LoanAgreement are both guaranteed by most of our direct and indirect subsidiaries and are secured by substantially all of our assets and most of the assets of most of our subsidiaries. The 2013 Revolving2016 Credit Facility and the Term Loan containAgreement contains various covenants providing for, among other things, maintenance of certain financial ratios and certain limitations on payment of dividends, common stock

repurchases, investments, acquisitions, indebtedness and capital expenditures. We were in compliance with all such covenants as of December 31, 2016 with respect to the 2016 Credit Agreement, and as of December 31, 2015 with respect to the 2013 Credit Agreement. A commitment fee is payable on the average daily unused amount underof the 20132016 Revolving Credit Facility, which ranges from 0.20%0.15% to 0.30%, based on certain financial tests. The fee iswas 0.20% of the unused amount as of December 31, 2013.2016. Borrowings under the 2013 Revolving2016 Credit Facility and the Term LoanAgreement bear interest at (1) a base rate which is the prime commercial lending rate announced by Bankplus a margin of Montreal from time to time (3.25% at December 31, 2013) plus 0.25%0.00% to 0.75%, based on certain financial tests, or (2) United States dollar LIBOR (0.17%0.76% at December 31, 2013)2016) plus 1.25%1.00% to 1.75%, based on certain financial tests. The base rate is determined by the greater of (a) the prime commercial lending rate announced by Bank of Montreal from time to time (3.75% at December 31, 2016), (b) the federal funds effective rate, plus ½ of 1.00%, (c) the daily one month LIBOR rate, plus 1.00%, or (d) 0.00%.

2013 2016 Revolving Credit Facility range from 1.25%1.00% to 1.75% of the respective face amounts of outstanding letters of credit and are chargedcomputed based on certain financial tests. We capitalized approximatelyan additional $3.0 million of debt issuance costs associated with the 20132016 Credit Agreement. This amount is beingDebt issuance costs are amortized over the life of the agreement and isare included as part of interest expense. In connection with the amendment and restatement of the 20112013 Credit Agreement, $0.3$0.1 million attributable to the acceleration of expense for debt issuance costs in connection with the 20112013 Credit Agreement was recorded as part of interest expense. We areexpense during the third quarter of 2016. The 2016 Term Loan required us to make principal payments on the Term Loan in installmentsof $5.0 million on the last day of March, June, September and December of each year, commencing with the calendar quarter ended December 31, 2016. On December 30, 2016, we made a payment of $100.0 million, of which $5.0 million represented our required quarterly payment and $95.0 million represented a prepayment of outstanding principal. Such prepayment was applied against the remaining mandatory quarterly payments on a ratable basis. As a result, commencing with the calendar quarter ending March 31, 2014, in the amount of $4.4 million, with a final2017, our required quarterly payment of allhas been reduced to $3.8 million. All unpaid principal and interest not yet paidis due and payable on November 25, 2018.August 3, 2021. As of December 31, 2013,2016 and December 31, 2015, the balance onof the 2016 Term Loan and the 2013 Term Loan was $350.0 million.$300.0 million and $315.0 million, respectively. As of December 31, 20132016 and December 31, 2012,2015, we had approximately $83.391.9 million and $84.099.0 million of letters of credit outstanding, respectively. We hadThere were $125.0 million in borrowings of $150.0 million outstanding under the 20112016 Revolving Credit Agreement atFacility as of December 31, 2012.2016. There were no borrowings outstanding under the 2013 Revolving Credit Facility as of December 31, 2013.2015.
On September 26, 2011, our Board of Directors authorized us to repurchase up to $100.0 million of our outstanding common stock. During 2013, we repurchased approximately 0.7 million shares of our common stock for approximately $26.1 million. Since the inception of this repurchase program, we have repurchased 2.8 million shares of our common stock for approximately $77.5 million, and there remains authorization for us to repurchase approximately $22.5 million of our shares under that authorization. On December 5, 2013, our Board of Directors authorized us to repurchase up to an additional $100.0 million of our outstanding common stock. As a result, $122.5 million was available for repurchase as of December 31, 2013. The repurchase program does not obligate us to acquire any particular amount of common stock and may be suspended, recommenced or discontinued at any time or from time to time without prior notice. Acquisitions under our repurchase program may be made from time to time to the extent permitted by securities laws and other legal requirements, including provisions in our credit agreement placing limitations on such repurchases. The repurchase program has been and will be funded from our operations.
The terms of our construction contracts frequently require that we obtain from surety companies (“Surety Companies”) and provide to our customers payment and performance bonds (“Surety Bonds”) as a condition to the award of such contracts. The Surety Bonds secure our payment and performance obligations under such contracts, and we have agreed to indemnify the Surety Companies for amounts, if any, paid by them in respect of Surety Bonds issued on our behalf. In addition, at the request of labor unions representing certain of our employees, Surety Bonds are sometimes provided to secure obligations for wages and benefits payable to or for such employees. Public sector contracts require Surety Bonds more frequently than private sector contracts, and accordingly, our bonding requirements typically increase as the amount of public sector work increases. As of December 31, 2013,2016, based on our percentage-of-completion of our projects covered by Surety Bonds, our aggregate estimated exposure, assuming defaults on all our then existing contractual obligations, was approximately $0.8 billion.$1.1 billion, which represents approximately 29% of our total backlog. The Surety Bonds are issued by Surety Companies in return for premiums, which vary depending on the size and type of bond.
We continually monitor our available limits of Surety Bonds, whichFrom time to time, we believe to be adequate, and discuss with our current and other Surety Bond providers the amountamounts of Surety Bonds that may be available to us based on our financial strength and the absence of any default by us on any Surety Bond issued on our behalf.behalf, and we believe those amounts are currently adequate for our needs. However, if we experience changes in our bonding relationships or if there are adverse changes in the surety industry, we may seek to satisfy certain customer requests for Surety Bonds by posting other forms of collateral in lieu of Surety Bonds such as letters of credit, or parent company guarantees or cash, seeking to convince customers to forego the requirement for Surety Bonds, by increasing our activities in our business segments that rarely require Surety Bonds such as theour building and industrial services segments, and/or by refraining from bidding for certain projects that require Surety Bonds. There can be no assurance that we willwould be able to effectuate alternatives to providing Surety Bonds to our customers or to obtain, on favorable terms, sufficient additional work that does not require Surety Bonds to replace projects requiring Surety Bonds that we may decide not to pursue.Bonds. Accordingly, if we were to experience a reduction in the availability of Surety Bonds, we could experience a material adverse effect on our financial position, results of operations and/or cash flows.
From time to time inIn the ordinary course of business, we, at times, guarantee obligations of our subsidiaries under certain contracts. Generally, we are liable under such an arrangement only if our subsidiary fails to perform its obligations under the contract. Historically, we have not incurred any substantial liabilities as a consequence of these guarantees.
We do not have any other material financial guarantees or off-balance sheet arrangements other than those disclosed herein.
We are a party to lawsuits and other proceedings in which other parties seek to recover from us amounts ranging from a few thousand dollars to over $10.0 million. We do not believe that any such matters will have a material adverse effect on our financial position, results of operations or liquidity.

On September 26, 2011, our Board of Directors authorized us to repurchase up to $100.0 million of our outstanding common stock. On December 5, 2013, October 23, 2014 and October 28, 2015, our Board of Directors authorized us to repurchase up to an additional $100.0 million, $250.0 million and $200.0 million of our outstanding common stock, respectively. During 2016, we repurchased approximately 1.5 million shares of our common stock for approximately $88.6 million. Since the inception of the repurchase programs through December 31, 2016, we have repurchased 11.4 million shares of our common stock for approximately $484.4 million. As of December 31, 2016, there remained authorization for us to repurchase approximately $165.6 million of our shares. The repurchase programs do not obligate the Company to acquire any particular amount of common stock and may be suspended, recommenced or discontinued at any time or from time to time without prior notice. We may repurchase our shares from time to time to the extent permitted by securities laws and other legal requirements, including provisions in our credit agreement placing limitations on such repurchases. The repurchase programs have been and will be funded from our operations.
We have paid quarterly dividends since October 25, 2011. We currently pay a regular quarterly dividend of $0.08 per share. Our 2016 Credit Agreement places limitations on the payment of dividends on our common stock. However, we do not believe that the terms of such agreement currently materially limit our ability to pay a quarterly dividend of $0.08 per share for the foreseeable future. The payment of dividends has been and will be funded from our operations.
Our primary source of liquidity has been, and is expected to continue to be, cash generated by operating activities. We also maintain our 20132016 Revolving Credit Facility that may be utilized, among other things, to meet short-term liquidity needs in the event cash generated by operating activities is insufficient or to enable us to seize opportunities to participate in joint ventures or to make acquisitions that may require access to cash on short notice or for any other reason. However, negativeNegative macroeconomic trends may have an adverse effect on liquidity. During economic downturns, there have been typically fewer small discretionary projects from the private sector, and our competitors have aggressively bid larger long-term infrastructure and public sector contracts. Short-term liquidity is also impacted by the type and length of construction contracts in place. During economic downturns, there were typically fewer small discretionary projects fromplace and large turnaround activities in our United States industrial services segment that are billed in arrears pursuant to contractual terms that are standard within the private sector, and our competitors aggressively bid larger long-term infrastructure and public sector contracts.industry. Performance of long duration contracts typically requires greater amounts of working capital. While we strive to maintain a net over-billed position with our customers,

33


there can be no assurance that a net over-billed position can be maintained. Our net over-billings, defined as the balance sheet accounts “Billings in excess of costs and estimated earnings on uncompleted contracts” less “Cost and estimated earnings in excess of billings on uncompleted contracts”, were $290.6358.5 million and $290.5311.5 million as of December 31, 20132016 and 2012,2015, respectively.
Long-term liquidity requirements can be expected to be met initially through cash generated from operating activities and our 20132016 Revolving Credit Facility. Based upon our current credit ratings and financial position, we can reasonably expect to be able to incur long-term debt to fund acquisitions. Over the long term, our primary revenue risk factor continues to be the level of demand for non-residential construction services and for building and industrial services, which is influenced by macroeconomic trends including interest rates and governmental economic policy. In addition, our ability to win and perform work is critical to meeting long-term liquidity requirements.
We are a party to lawsuits and other proceedings in which other parties seek to recover from us amounts ranging from a few thousand dollars to over $10.0 million. We do not believe that any such matters will have a materially adverse effect on our financial position, results of operations or liquidity.
We believe that our current cash balances, and ourthe borrowing capacity available under our 20132016 Revolving Credit Facility orand other forms of financing available to us through borrowings, combined with cash expected to be generated from operations, will be sufficient to provide our short-term and foreseeable long-term liquidity and meet our expected capital expenditure requirements.
On September 26, 2011, we announced plans to pay a regular quarterly dividend of $0.05 per common share. We have paid quarterly dividends since October 25, 2011. On December 7, 2012, our Board of Directors declared a special dividend of $0.25 per share, payable in December 2012, and announced its intention to increase the regular quarterly dividend to $0.06 per share. In addition, at the December 7, 2012 meeting of our Board of Directors, the regular quarterly dividend that would have been paid in January 2013 was declared, its amount increased to $0.06 per share and its payment date accelerated to December 28, 2012. In December 2013, our Board of Directors announced its intention to increase the regular quarterly dividend to $0.08 per share commencing with the dividend to be paid in the first quarter of 2014. We expect that such quarterly dividends will be paid in the foreseeable future. Prior to October 25, 2011, no cash dividends had been paid on the Company's common stock. Our credit agreement places limitations on the payment of dividends on our common stock. However, we do not believe that the terms of the credit agreement currently materially limit our ability to pay a quarterly dividend of $0.08 per share for the foreseeable future. The payment of dividends has been and will be funded from our operations.
Certain Insurance Matters
As of December 31, 20132016 and 2012,2015, we utilized approximately $83.3$91.5 million and $84.0$97.8 million, respectively, of letters of credit obtained under our 20132016 Revolving Credit Facility and our 20112013 Revolving Credit Agreement,Facility, respectively, as collateral for insurance obligations.
New Accounting Pronouncements
We review new accounting standards to determine the expected financial impact, if any, that the adoption of such standards will have. As of the filing of this Annual Report on Form 10-K, there were no new accounting standards that were projected to have a material impact on our consolidated financial position and/or results of operations or liquidity.operations. See Note 2 - Summary of Significant Accounting Policies of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data for further information regarding new accounting standards, recently issued and/including the anticipated dates of adoption and the effects on our consolidated financial position, results of operations or adopted by us.liquidity.
Application of Critical Accounting Policies
Our consolidated financial statements are based on the application of significant accounting policies, which require management to make significant estimates and assumptions. Our significant accounting policies are described in Note 2 - Summary of Significant Accounting Policies of the notes to consolidated financial statements included in Item 8. Financial Statements and Supplementary Data of this Form 10-K. We believe that some of the more critical judgment areas in the application of accounting policies that

affect our financial condition and results of operations are the impact of changes in the estimates and judgments pertaining to: (a) revenue recognition from (i) long-term construction contracts for which the percentage-of-completion method of accounting is used and (ii) services contracts; (b) collectibility or valuation of accounts receivable; (c) insurance liabilities; (d) income taxes; and (e) goodwill and identifiable intangible assets.
Revenue Recognition from Long-term Construction Contracts and Services Contracts
We believe our most critical accounting policy is revenue recognition from long-term construction contracts for which we use the percentage-of-completion method of accounting. Percentage-of-completion accounting is the prescribed method of accounting for long-term contracts in accordance with Accounting Standards Codification (“ASC”) Topic 605-35, “Revenue Recognition-Construction-Type and Production-Type Contracts”, and, accordingly, is the method used for revenue recognition within our

34


industry. Percentage-of-completion is measured principally by the percentage of costs incurred to date for each contract to the estimated total costs for such contract at completion. Certain of our electrical contracting business units measure percentage-of-completion by the percentage of labor costs incurred to date for each contract to the estimated total labor costs for such contract. Pre-contract costs from our construction projects are generally expensed as incurred. Application of percentage-of-completion accounting results in the recognition of costs and estimated earnings in excess of billings on uncompleted contracts in ourthe Consolidated Balance Sheets. Costs and estimated earnings in excess of billings on uncompleted contracts reflected in the Consolidated Balance Sheets arise when revenues have been recognized but the amounts cannot be billed under the terms of contracts. Such amounts are recoverable from customers based upon various measures of performance, including achievement of certain milestones, completion of specified units or completion of a contract.
Costs and estimated earnings in excess of billings on uncompleted contracts also include amounts we seek or will seek to collect from customers or others for errors or changes in contract specifications or design, contract change orders in dispute or unapproved as to both scope and price or other customer-related causes of unanticipated additional contract costs (claims and unapproved change orders). Such amounts are recorded at estimated net realizable value and take into account factors that may affect our ability to bill and ultimately collect unbilled revenues and collect amounts after billing.revenues. The profit associated with claim amounts is not recognized until the claim has been settled and payment has been received. During 2012,2015, we recognized approximately $9.5revenues of $12.1 million as a result of profit from the settlement and payment of two claimsa claim within theour United States electricalmechanical construction and facilities services segment.segment, which represented the partial recovery of cost on a project in which we incurred significant losses in a prior year. There waswere no other significant profit recognized from settlements or paymentpayments of claims in 2013.2016 and 2015. As of December 31, 20132016 and 2012,2015, costs and estimated earnings in excess of billings on uncompleted contracts included unbilled revenues for unapproved change orders of approximately $19.221.6 million and $13.818.9 million, respectively, and claims of approximately $0.46.0 million and $0.70.9 million, respectively. In addition, accounts receivable as of December 31, 20132016 and 20122015 included claims of approximately $2.90.0 million and $0.80.3 million, respectively. In addition, there areThere were contractually billed amounts and retention related to such contracts with unapproved change orders and claims of approximately $56.180.5 million and $41.052.0 million as of December 31, 20132016 and 2012,2015, respectively. Generally,For contracts in claim status, contractually billed amounts will generally not be paid by the customer to us until final resolution of related claims. Due to uncertainties inherent in estimates employed in applying percentage-of-completion accounting, estimates may be revised as project work progresses. Application of percentage-of-completion accounting requires that the impact of revised estimates be reported prospectively in the consolidated financial statements. In addition to revenue recognition for long-term construction contracts, we recognize revenues from the performance of services for maintenance, repair and retrofit work consistent with the performance of the services, which are generally on a pro-rata basis over the life of the contractual arrangement. Expenses related to all services arrangements are recognized as incurred. Revenues related to the engineering, manufacturing and repairing of shell and tube heat exchangers are recognized when the product is shipped and all other revenue recognition criteria have been met. Costs related to this work are included in inventory until the product is shipped. Provisions for the entirety of estimated losses on contracts are made in the period in which such losses are determined. During 2013,2016, we recognized aggregateincurred $19.4 million of losses on a transportation project within our United States electrical construction and facilities services segment as a result of approximately $24.5 million associated with two contractsproductivity issues attributable to unfavorable job-site conditions. In addition, within the United States mechanical construction and facilities services segment, we incurred $18.3 million of losses on a project at a process facility as a result of a changecontract dispute with our customer and $9.6 million of losses on an institutional project due to project delays and unfavorable job-site conditions. There were no other significant losses recognized in contract estimates.2016 and 2015.
Accounts Receivable
We are required to estimate the collectibility of accounts receivable. A considerable amount of judgment is required in assessing the likelihood of realization of receivables. Relevant assessment factors include the creditworthiness of the customer, our prior collection history with the customer and related aging of past due balances. The provision for doubtful accounts during 2013, 20122016, 2015 and 20112014 amounted to approximately $3.56.2 million, $1.22.9 million and $2.22.9 million, respectively. At December 31, 20132016 and 2012,2015, our accounts receivable of $1,268.21,495.4 million and $1,222.01,359.9 million, respectively, included allowances for doubtful accounts of $11.912.3 million and $11.511.2 million, respectively. The increase in our allowance for doubtful accounts was primarily due to thean increase in ourthe provision for doubtful accounts, primarily within our United States building services segment.partially offset by the write-off of previously reserved accounts receivable. Specific accounts receivable are evaluated when we believe a customer may not be able to meet its financial obligations due to deterioration of its

financial condition or its credit ratings. The allowance for doubtful accounts requirements are based on the best facts available and are re-evaluated and adjusted on a regular basis as additional information is received.
Insurance Liabilities
We have loss payment deductibles for certain workers'workers’ compensation, automobile liability, general liability and property claims, have self-insured retentions for certain other casualty claims and are self-insured for employee-related health care claims. Losses are recorded based upon estimates of our liability for claims incurred and for claims incurred but not reported. The liabilities are derived from known facts, historical trends and industry averages utilizing the assistance of an actuary to determine the best estimate for the majority of these obligations. We believe the liabilities recognized on our balance sheets for these obligations are adequate. However, such obligations are difficult to assess and estimate due to numerous factors, including severity of injury, determination of liability in proportion to other parties, timely reporting of occurrences and effectiveness of safety and risk management programs. Therefore, if our actual experience differs from the assumptions and estimates used for recording the liabilities, adjustments may be required and will be recorded in the period that the experience becomes known. Our estimated

net insurance liabilities for workers'workers’ compensation, automobile liability, general liability and property claims increased by $10.7$12.3 million for the year ended December 31, 20132016 compared to the year ended December 31, 2012,2015, primarily due to acquisitions.higher revenues, including the impact of acquired companies. If our estimated net insurance liabilities for workers'workers’ compensation, automobile liability, general liability and property claims were to increase by 10%, it would have resulted in $13.7$15.7 million of additional expense for the year ended December 31, 2013.2016.
Income Taxes
We had net deferred income tax liabilities at December 31, 20132016 and 20122015 of $126.8$117.4 million and $35.6$120.6 million, respectively, primarily resulting from differences between the carrying value and income tax basis of certain identifiable intangible assets and depreciable fixed assets, which will impact our taxable income in future periods. Included within these net deferred income tax liabilities are $139.4 million and $121.4 million of deferred income tax assets as of December 31, 2016 and 2015, respectively. A valuation allowance is required when it is more likely than not that all or a portion of a deferred income tax asset will not be realized. As of December 31, 20132016 and 2012,2015, the total valuation allowance on deferred income tax assets, related solely to state net operating carryforwards, was approximately $2.2$3.5 million and $2.5$0.8 million, respectively. WeThe ultimate realization of deferred income tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Based on our taxable income, which has generally exceeded the amount of our net deferred tax asset balance and projections of future taxable income, we have determined that as of December 31, 2013, a valuation allowance wasit is more likely than not required on any ofthat the remainingnet deferred income tax assets because of significant deferred tax liabilities after consideration of the above mentioned deferred tax liabilities related to indefinite-lived intangible assets and projected future income.will be realized.
Goodwill and Identifiable Intangible Assets
As of December 31, 2013,2016, we had $834.8979.6 million and $541.5487.4 million, respectively, of goodwill and net identifiable intangible assets (primarily consisting of our contract backlog, developed technology/vendor network, customer relationships, non-competition agreements and trade names), primarily arising out of the acquisition of companies. As of December 31, 2012,2015, goodwill and net identifiable intangible assets were $566.6843.2 million and $343.7472.8 million, respectively. The changes to goodwill since December 31, 2015 were related to the acquisition of two companies in 2016 and a purchase price adjustment related to an acquisition made in 2015. The determination of related estimated useful lives for identifiable intangible assets and whether those assets are impaired involves significant judgments based upon short and long-term projections of future performance. These forecasts reflect assumptions regarding the ability to successfully integrate acquired companies, as well as macroeconomic conditions. ASC Topic 350, “Intangibles-Goodwill and Other” (“ASC 350”) requires goodwill and other identifiable intangible assets with indefinite useful lives not be amortized, but instead must be tested at least annually for impairment (which we test each October 1, absent any impairment indicators), and be written down if impaired. ASC 350 requires that goodwill be allocated to its respective reporting unit and that identifiable intangible assets with finite lives be amortized over their useful lives.
We test for impairment of our goodwill at the reporting unit level. Our reporting units are consistent with the reportable segments identified in Note 17, "Segment Information"“Segment Information”, of the notes to consolidated financial statements.statements included in Item 8. Financial Statements and Supplementary Data. In assessing whether our goodwill is impaired, we first qualitatively assess whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount using various factors. If after this assessment we are unable to determine that the fair value of a reporting unit exceeds the carrying amount, we proceed toutilize the two-step process as prescribed by ASC 350. The first step of this test compares the fair value of the reporting unit, determined based upon discounted estimated future cash flows, to the carrying amount, including goodwill. If the fair value exceeds the carrying amount, no further workanalysis is required and no impairment loss is recognized. If the carrying amount of the reporting unit exceeds the fair value, the goodwill of the reporting unit is potentially impaired and step two of the goodwill impairment test would need to be performed to measure the amount of an impairment loss, if any. In the second step, the impairment is computed by comparing the implied fair value of the reporting unit'sunit’s goodwill with the carrying amount of the goodwill. If the carrying amount of the reporting unit'sunit’s goodwill is greater than the implied fair value of its goodwill, an impairment loss in the amount of the excess is recognized and charged to operations. The weighted average cost of capital used in our annual testing for impairment as of October 1, 20132016 was 12.1%11.4%, 12.6% 11.0%

and 11.1%11.5% for our domestic construction segments, our United States building services segment and our United States industrial services segment, respectively. The perpetual growth rate used for our annual testing was 2.7% for all of our domestic segments. Unfavorable changes in these key assumptions may affect future testing results and cause us to fail step one of the goodwill impairment testing process. For example, keeping all other assumptions constant, a 50 basis point increase in the weighted average costs of capital would cause the estimated fair value of our United StatedStates industrial services segment to approach its carrying value. A 50 basis point increase in the weighted average costs of capital would not significantly reduce the excess of the estimated fair value compared to the carrying value for any of our other domestic segments. In addition, keeping all other assumptions constant, a 50 basis point reduction in the perpetual growth rate would not significantly reduce the excess of the estimated fair value compared to the carrying value for any of our domestic segments. For the years ended December 31, 2013, 20122016, 2015 and 2011,2014, no impairment of our goodwill was recognized.
As of December 31, 2013,2016, we had $834.8979.6 million of goodwill on our balance sheet and, of this amount, approximately 46.1%39.3% relates to our United States industrial services segment, approximately 27.4%25.0% relates to our United States building services segment, approximately 26.0%23.1% relates to our United States mechanical construction and facilities services segment and approximately 0.5%12.6% relates to our United States electrical construction and facilities services segment. As of the date of our latest impairment test, the carrying values of our United States industrial services, United States building services, United States mechanical construction and facilities services and United States electrical construction and facilities services segments were approximately $744.9$695.1 million, $487.7$462.4 million, $237.7$277.3 million and $58.7$268.8 million, respectively. The fair values of our United States industrial services, United

36


States building services, United States mechanical construction and facilities services and United States electrical construction and facilities services segments exceeded their carrying values by approximately $45.0$69.2 million, $126.0$268.6 million, $519.9$791.4 million and $366.8$526.3 million, respectively.
We also test for the impairment of trade names that are not subject to amortization by calculating the fair value of such trade names using the “relief from royalty payments” methodology. This approach involves two steps: (a) estimating reasonable royalty rates for each trade name and (b) applying these royalty rates to a net revenue stream and discounting the resulting cash flows to determine fair value. This fair value is then compared with the carrying value of each trade name. If the carrying amount of the trade name is greater than the implied fair value of the trade name, an impairment in the amount of the excess is recognized and charged to operations. The annual impairment review of our trade names for the yearyears ended December 31, 20112016 and 2014 resulted in a $1.0$2.4 million and $1.5 million, respectively, of non-cash impairment chargecharges as a result of a change in the fair value of subsidiary trade names associated with certain prior acquisitions reported within our United States buildingmechanical construction and facilities services segment. This impairment primarily resulted from both lower forecasted revenues from,segment and operating margins at, specific companies within our United States building services segment. For the yearsyear ended December 31, 2013 and 2012,2015, no impairment of our trade names was recognized.
In addition, we review for the impairment of other identifiable intangible assets that are being amortized whenever facts and circumstances indicate that their carrying values may not be fully recoverable. This test compares their carrying values to the undiscounted pre-tax cash flows expected to result from the use of the assets. If the assets are impaired, the assets are written down to their fair values, generally determined based on their future discounted cash flows. Based on facts and circumstances that indicated an impairment may exist, we performed an impairment review of certain of our other identifiable intangible assets for the year ended December 31, 2011. As a result of this review, we recognized a $2.8 million non-cash impairment charge as a result of a change in the fair value of customer relationships associated with certain prior acquisitions reported within our United States building services segment for the year ended December 31, 2011. For the years ended December 31, 20132016, 2015 and 2012,2014, no impairment of our other identifiable intangible assets was recognized.
We have certain businesses, particularly within our United States industrial services segment, whose results are highly impacted by the demand for some of our offerings within the industrial and oil and gas markets. Future performance of this segment, along with a continued evaluation of the conditions of its end user markets, will be important to ongoing impairment assessments. Should itsthis segment’s actual results suffer a decline or expected future results be revised downward, the risk of goodwill impairment or impairment of other identifiable intangible assets would increase.
Our development of the present value of future cash flow projections used in impairment testing is based upon assumptions and estimates by management from a review of our operating results, business plans, anticipated growth rates and margins, and weighted average cost of capital, among others. Those assumptions and estimates can change in future periods, and other factors used in assessing fair value are outside the control of management, such as interest rates. There can be no assurances that estimates and assumptions made for purposes of our goodwill and identifiable intangible asset impairment testing will prove to be accurate predictions of the future. If our assumptions regarding future business performance or anticipated growth rates and/or margins are not achieved, or there is a rise in interest rates, we may be required as we did in 2011, to record further goodwill and/or identifiable intangible asset impairment charges in future periods.
During 2011, we recognized a $3.8 million non-cash impairment charge as discussed above. Of this amount, $2.8 million related to customer relationships and $1.0 million related to trade names. It is not possible at this time to determine if any such future impairment charge would result or, if it does, whether such a charge would be material.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
We have not used any derivative financial instruments during the years ended December 31, 20132016 and 2012,2015, including trading or speculating on changes in interest rates or commodity prices of materials used in our business.
We are exposed to market risk for changes in interest rates for borrowings under the 20132016 Credit Agreement.Agreement, which provides for a revolving credit facility and a term loan. Borrowings under the 20132016 Credit Agreement bear interest at variable rates. For further information on borrowing rates and interest rate sensitivity, refer to the Liquidity and Capital Resources discussion in Item 7. Management'sManagement’s Discussion and Analysis of Financial Condition and Results of Operations. As of December 31, 2013,2016, there were no borrowings of $125.0 million outstanding under the 20132016 Revolving Credit Facility and the balance onof the 2016 Term Loan was $350.0$300.0 million. Based on the $350.0$425.0 million borrowings outstanding onunder the 20132016 Credit Agreement, if overall interest rates were to increase by 25100 basis points, interest expense, net of income taxes, would increase by approximately $0.4$2.6 million infor the next twelve months. Conversely, if overall interest rates were to decrease by 25100 basis points, interest expense, net of income taxes, would decrease by approximately $0.4$2.6 million infor the next twelve months.
We are also exposed to construction market risk and its potential related impact on accounts receivable or costs and estimated earnings in excess of billings on uncompleted contracts. The amounts recorded may be at risk if our customers'customers’ ability to pay these obligations is negatively impacted by economic conditions. We continually monitor the creditworthiness of our customers and

maintain on-going discussions with customers regarding contract status with respect to change orders and billing terms. Therefore, we believe we take appropriate action to manage market and other risks, but there is no assurance that we will be able to reasonably identify all risks with respect to collectibility of these assets. See also the previous discussions of Revenue Recognition from Long-term Construction Contracts and Services Contracts and Accounts Receivable under Application of Critical Accounting Policies in Item 7. Management'sManagement’s Discussion and Analysis of Financial Condition and Results of Operations.
Amounts invested in our foreign operations are translated into U.S. dollars at the exchange rates in effect at year end. The resulting translation adjustments are recorded as accumulated other comprehensive income (loss), a component of equity, in ourthe Consolidated Balance Sheets. We believe the exposure to the effects that fluctuating foreign currencies may have on our consolidated results of operations is limited because the foreign operations primarily invoice customers and collect obligations in their respective local currencies. Additionally, expenses associated with these transactions are generally contracted and paid for in their same local currencies.
In addition, we are exposed to market risk of fluctuations in certain commodity prices of materials, such as copper and steel, which are used as components of supplies or materials utilized in our construction, and building services and industrial services operations. We are also exposed to increases in energy prices, particularly as they relate to gasoline prices for our fleet of over 8,5009,500 vehicles. While we believe we can increase our contract prices to adjust for some price increases in commodities, there can be no assurance that price increases, of commodities, if they were to occur, would be recoverable. Additionally, our fixed price contracts do not allow us to adjust our prices and, as a result, increases in material or fuel costs could reduce our profitability with respect to projects in progress.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
NOTE 1- NATURE OF OPERATIONS
References to the “Company,” “EMCOR,” “we,” “us,” “our” and similar words refer to EMCOR Group, Inc. and its consolidated subsidiaries unless the context indicates otherwise.
We are one of the largest electrical and mechanical construction and facilities services firms in the United States. In addition, we provide a number of building services and industrial services. We specialize principally in providing construction services relating to electrical and mechanical systems in all types of non-residential and certain residential facilities and in providing various services relating to the operation, maintenance and management of facilities, including refineries and petrochemical plants.
NOTE 2- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Principles of Consolidation
The consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries.subsidiaries and joint ventures. Significant intercompany accounts and transactions have been eliminated. All investments over which we exercise significant influence, but do not control (a 20% to 50% ownership interest), are accounted for using the equity method of accounting. Additionally, we participate in a joint venture with another company, and we have consolidated this joint venture as we have determined that through our participation we have a variable interest and are the primary beneficiary as defined by the Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) Topic 810, “Consolidation”.
For joint ventures that have been accounted for using the consolidation method of accounting, noncontrolling interest representsinterests represent the allocation of earnings to our joint venture partners who either have a minority-ownership interest in the joint venture or are not at risk for the majority of losses of the joint venture.
The results of operations of companies acquired have been included in the results of operations from the date of the respective acquisition.
Principles of Preparation
The preparation of the consolidated financial statements, in conformity with accounting principles generally accepted in the United States, requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates.
During the third quarter of 2013,2014, we completedceased construction operations in the acquisitionUnited Kingdom. The results of RepconStrickland, Inc. (“RSI”), a leading provider of turnaround and specialty services to the North American refinery and petrochemical markets. In connection with the acquisition of RSI and to reflect changes in our internal reporting structure and the information used by management to make operating decisions and assess performance, we created a new segment that includes RSI and certain businesses that had been partconstruction operations of our United States facilities services segment. The newKingdom segment is called the United States industrial services segment and the segment formerly named the United States facilities services segment has been renamed the United States building services segment.
Our reportable segments have been restated infor all periods are presented to reflect the changes in our segments referred to above.as discontinued operations. The segment formally named the United Kingdom construction and facilitiesbuilding services segment has been renamed the United Kingdom construction and building services segment. In addition, the results of operations for all periods presented reflect: (a) discontinued operations accounting due to the disposition in August 2011 of our Canadian subsidiary and (b) certain reclassifications of prior period amounts from our United States building services segment to our United States mechanical construction and facilities services segment due to changes in our internal reporting structure.
Revenue Recognition
Revenues from long-term construction contracts are recognized on the percentage-of-completion method in accordance with ASC Topic 605-35, “Revenue Recognition-Construction-Type and Production-Type Contracts”. Percentage-of-completion is measured principally by the percentage of costs incurred to date for each contract to the estimated total costs for such contract at completion. Certain of our electrical contracting business units measure percentage-of-completion by the percentage of labor costs incurred to date for each contract to the estimated total labor costs for such contract. Pre-contract costs from our construction projects are generally expensed as incurred. Revenues from the performance of services for maintenance, repair and retrofit work are recognized consistent with the performance of the services, which are generally on a pro-rata basis over the life of the contractual arrangement. Expenses related to all services arrangements are recognized as incurred. Revenues related to the engineering,

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (Continued)

manufacturing and repairing of shell and tube heat exchangers are recognized when the product is shipped and all other revenue recognition criteria have been met. Costs related to this work are included in inventory until the product is shipped. In the case of customer change orders for uncompleted long-term construction contracts, estimated recoveries are included for work performed in forecasting ultimate profitability on certain contracts. Due to uncertainties inherent in the estimation process, it is possible that completion costs, including those arising from contract penalty provisions and final contract settlements, will be revised in the near-term. Such revisions to costs and income are recognized in the period in which the revisions are determined. Provisions for the entirety of estimated losses on uncompleted contracts are made in the period in which such losses are determined. During 2013,2016, we recognized aggregateincurred $19.4 million of losses of approximately $24.5 million associated with two contractson a transportation project within the United States mechanicalelectrical construction and facilities services segment as a result of productivity issues attributable to unfavorable job-site conditions. In addition, within the United

States mechanical construction and facilities services segment, we incurred $18.3 million of losses on a changeproject at a process facility as a result of a contract dispute with our customer and $9.6 million of losses on an institutional project due to project delays and unfavorable job-site conditions. There were no significant losses recognized in contract estimates.2015.
Costs and estimated earnings on uncompleted contracts
Costs and estimated earnings in excess of billings on uncompleted contracts arise in the consolidated balance sheets when revenues have been recognized but the amounts cannot be billed under the terms of the contracts. Such amounts are recoverable from customers upon various measures of performance, including achievement of certain milestones, completion of specified units, or completion of a contract. Also included in costs and estimated earnings on uncompleted contracts are amounts we seek or will seek to collect from customers or others for errors or changes in contract specifications or design, contract change orders in dispute or unapproved as to both scope and/or price or other customer-related causes of unanticipated additional contract costs (claims and unapproved change orders). Such amounts are recorded at estimated net realizable value when realization is probable and can be reasonably estimated. No profit is recognized on construction costs incurred in connection with claim amounts. Claims and unapproved change orders made by us involve negotiation and, in certain cases, litigation. In the event litigation costs are incurred by us in connection with claims or unapproved change orders, such litigation costs are expensed as incurred, although we may seek to recover these costs. We believe that we have established legal bases for pursuing recovery of our recorded unapproved change orders and claims, and it is management'smanagement’s intention to pursue and litigate such claims, if necessary, until a determination or settlement is reached. Unapproved change orders and claims also involve the use of estimates, and it is reasonably possible that revisions to the estimated recoverable amounts of recorded claims and unapproved change orders may be made in the near term. If we do not successfully resolve these matters, a net expense (recorded as a reduction in revenues) may be required, in addition to amounts that may have been previously provided for. We record the profit associated with the settlement of claims upon receipt of final payment. During 2012,2015, we recognized approximately $9.5revenues of $12.1 million as a result of profit from the settlement and payment of two claimsa claim within theour United States electricalmechanical construction and facilities services segment.segment, which represented the partial recovery of cost on a project in which we incurred significant losses in a prior year. There waswere no significant profit recognized from settlements or paymentpayments of claims in 2013.2016. Claims against us are recognized when a loss is considered probable and amounts are reasonably determinable.

of approximately $2.9 million and $0.8 million, respectively. Additionally, there are contractually billed amounts and retention related to such contracts of $56.1 million and $41.0 million as of December 31, 2013 and 2012, respectively. Generally, contractually billed amounts will not be paid by the customer to us until final resolution of related claims.
Classification of Contract Amounts
In accordance with industry practice, we classify as current all assets and liabilities relating to the performance of long-term contracts. The term of our contracts ranges from one month to four years and, accordingly, collection or payment of amounts relating to these contracts may extend beyond one year. Accounts receivable at December 31, 20132016 and 20122015 included $189.7222.6 million and $178.6189.2 million, respectively, of retainage billed under terms of our contracts. We estimate that approximately 85%77% of this retainage recorded at December 31, 2013 will be collected during 2014.2017. Accounts payable at December 31, 20132016 and 20122015 included $47.040.1 million and $39.734.6 million, respectively, of retainage withheld under terms of the contracts. We estimate that approximately 95%74% of this retainage withheld at December 31, 2013 will be paid during 2014.2017.
Cash and cash equivalents
For purposes of the consolidated financial statements, we consider all highly liquid instruments with original maturities of three months or less to be cash equivalents. We maintain a centralized cash management system whereby our excess cash balances are invested in high quality, short-term money market instruments, which are considered cash equivalents. We have cash balances in certain of our domestic bank accounts that exceed federally insured limits.
Allowance for Doubtful Accounts
Accounts receivable are recorded at the invoiced amount and do not bear interest. The Company maintains an allowance for doubtful accounts. This allowance is based upon the best estimate of the probable losses in existing accounts receivable. The Company determines the allowances based upon individual accounts when information indicates the customers may have an inability to meet their financial obligations, as well as historical collection and write-off experience. These amounts are re-evaluated and adjusted on a regular basis as additional information is received. Actual write-offs are charged against the allowance when collection efforts have been unsuccessful. At December 31, 20132016 and 20122015, our accounts receivable of $1,268.21,495.4 million and $1,222.01,359.9 million, respectively, included allowances for doubtful accounts of $11.912.3 million and $11.511.2 million, respectively. The provision for doubtful accounts during 20132016, 20122015 and 20112014 amounted to approximately $3.56.2 million, $1.22.9 million and $2.22.9 million, respectively.
Inventories
Inventories are stated at the lower of cost or market. Cost is determined principally using the average cost method.
Property, plant and equipment
Property, plant and equipment is stated at cost. Depreciation, including amortization of assets under capital leases, is recorded principally using the straight-line method over estimated useful lives of 3 to 10 years for machinery and equipment, 3 to 7 years for vehicles, furniture and fixtures and computer hardware/software, and 25 years for buildings. Leasehold improvements are amortized over the shorter of the remaining life of the lease term or the expected service life of the improvement.
The carrying values of property, plant and equipment are reviewed for impairment whenever facts and circumstances indicate that the carrying amount may not be fully recoverable. In performing this review for recoverability, property, plant and equipment is assessed for possible impairment by comparing their carrying values to their undiscounted net pre-tax cash flows expected to result from the use of the asset. Impaired assets are written down to their fair values, generally determined based on their estimated future discounted cash flows. Based on the results of our testing for the years ended December 31, 20132016, 20122015 and 20112014, no impairment of property, plant and equipment was recognized.
Goodwill and Identifiable Intangible Assets
Goodwill and other identifiable intangible assets with indefinite lives that are not being amortized, such as trade names, are instead tested at least annually for impairment (which we test each October 1, absent any impairment indicators) and are written down if impaired. Identifiable intangible assets with finite lives are amortized over their useful lives and are reviewed for impairment whenever facts and circumstances indicate that their carrying values may not be fully recoverable. See Note 8 - Goodwill and Identifiable Intangible Assets of the notes to consolidated financial statements for additional information.

Insurance Liabilities
Our insurance liabilities are determined actuarially based on claims filed and an estimate of claims incurred but not yet reported. At December 31, 20132016 and 20122015, the estimated current portion of undiscounted insurance liabilities of $29.242.5 million and $25.529.9 million, respectively, were included in “Other accrued expenses and liabilities” in the accompanying Consolidated Balance Sheets. The estimated non-current portion of the undiscounted insurance liabilities included in “Other long-term obligations” at December 31, 20132016 and 20122015 were $112.8167.9 million and $108.1114.3 million, respectively. During 2016, the Company began reporting its insurance liabilities on a gross basis, resulting in the presentation of current anticipated insurance recoveries of $10.8 million included in “Prepaid expenses and other” and non-current anticipated insurance recoveries of $43.0 million included in “Other assets” in the accompanying Consolidated Balance Sheets. Prior to 2016, insurance liabilities were presented net of estimated insurance recoveries.
Foreign Operations
The financial statements and transactions of our foreign subsidiaries are maintained in their functional currency and translated into U.S. dollars in accordance with ASC Topic 830, “Foreign Currency Matters”. Translation adjustments have been recorded as “Accumulated other comprehensive loss”, a separate component of “Equity”.
Income Taxes
We account for income taxes in accordance with the provisions of ASC Topic 740, “Income Taxes” (“ASC 740”). ASC 740 requires an asset and liability approach which requires the recognition of deferred income tax assets and deferred income tax liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Valuation allowances are established when necessary to reduce deferred income tax assets when it is more likely than not that a tax benefit will not be realized.
We account for uncertain tax positions in accordance with the provisions of ASC 740. We recognize accruals of interest related to unrecognized tax benefits as a component of the income tax provision.
Valuation of Share-Based Compensation Plans
We have various types of share-based compensation plans and programs, which are administered by our Board of Directors or its Compensation and Personnel Committee. See Note 13 - Share-Based Compensation Plans of the notes to consolidated financial statements for additional information regarding the share-based compensation plans and programs.
We account for share-based payments in accordance with the provisionprovisions of ASC Topic 718, “Compensation-Stock Compensation” (“ASC 718”). ASC 718 requires that all share-based payments issued to acquire goods or services, including grants of employee stock options, be recognized in the statement of operations based on their fair values, net of estimated forfeitures. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Compensation expense related to share-based awards is recognized over the requisite service period, which is generally the vesting period. For shares subject to graded vesting, our policy is to apply the straight-line method in recognizing compensation expense. ASC 718 requires the benefits of tax deductions in excess of recognized compensation expense to be reported as a financing cash inflow, rather than as an operating cash inflow onrecognized in the Consolidated Statements of Cash Flows. This requirement reduces net operating cash flows and increases net financing cash flows.Operations when the underlying awards vest or are settled.
New Accounting Pronouncements
OnIn January 1, 2013, we adopted2017, an accounting pronouncement giving companieswas issued by the optionFinancial Accounting Standards Board (“FASB”) to perform a qualitative impairment assessmentsimplify the accounting for their indefinite-lived intangible assetsgoodwill impairment. This guidance eliminates the requirement that may allow them to skipan entity calculates the annual fair value calculation. To perform a qualitative assessment, a company must identify and evaluate changes in economic, industry and company-specific events and circumstances that could affect the significant inputs used to determine theimplied fair value of goodwill when measuring an indefinite-lived intangible asset.impairment charge. Instead, an entity would record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value. This pronouncement is effective for fiscal years beginning after December 15, 2019, with early adoption permitted. The adoption ofis required to be applied on a prospective basis. We do not believe this pronouncement did notguidance will have any effecta material impact on our financial position or results of operations, though it may impact the manner in which we perform future or prospective testing for indefinite-lived intangible asset impairment.
On January 1, 2013, we adopted an accounting pronouncement requiring preparers to report, in one place, information about reclassifications out of accumulated other comprehensive income ("AOCI"). It also required companies to report changes in AOCI balances. Public companies must provide the required information (e.g., changes in AOCI balances and reclassifications out of AOCI) in interim and annual periods. The adoption of this pronouncement did not have any effect on our financial position and/or results of operations.
In March 2016, we adopted the accounting pronouncement issued by the FASB to update guidance on how companies account for certain aspects of share-based payments to employees. This pronouncement is effective for fiscal years beginning after December 15, 2016, and interim periods within those years, with early adoption permitted. This guidance requires all income tax effects of awards to be recognized in the income statement when the awards vest or are settled and changes the presentation of excess tax benefits on the statement of cash flows. We adopted these provisions on a prospective basis. In addition, this pronouncement

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - (Continued)

changes guidance on: (a) accounting for forfeitures of share-based awards and (b) employers’ accounting for an employee’s use of shares to satisfy the employer’s statutory income tax withholding obligation. As a result of the adoption, we recorded an adjustment to retained earnings of $1.0 million to recognize net operating loss carryforwards, net of a valuation allowance, attributable to excess tax benefits on stock compensation that had not been previously recognized to additional paid in capital. The adoption of this pronouncement did not have a material impact on our financial position and/or results of operations.
In February 2016, an accounting pronouncement was issued by the FASB to replace existing lease accounting guidance. This pronouncement is intended to provide enhanced transparency and comparability by requiring lessees to record right-of-use assets and corresponding lease liabilities on the balance sheet for most leases. Expenses associated with leases will continue to be recognized in a manner similar to current accounting guidance. This pronouncement is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted. The adoption is required to be applied on a modified retrospective basis for each prior reporting period presented. We have not yet determined the effect that the adoption of this pronouncement may have on our financial position and/or results of operations.
On January 1, 2016, we adopted the accounting pronouncement issued by the FASB which eliminates the requirement that an acquirer in a business combination account for measurement-period adjustments retrospectively. Instead, an acquirer will recognize a measurement-period adjustment during the period in which it determines the amount of the adjustment. The adoption of this pronouncement did not have a material impact on our financial position and/or results of operations.
On January 1, 2016, we adopted the accounting pronouncement issued by the FASB to update the guidance related to the presentation of debt issuance costs. This guidance requires debt issuance costs, related to a recognized debt liability, be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability rather than being presented as an asset. We adopted this pronouncement on a retrospective basis, and the adoption did not have a material impact on our financial position and/or results of operations.
In November 2015, an accounting pronouncement was issued by the FASB to simplify the presentation of deferred income taxes within the balance sheet. This pronouncement eliminates the requirement that deferred tax assets and liabilities are presented as current or noncurrent based on the nature of the underlying assets and liabilities. Instead, the pronouncement requires all deferred tax assets and liabilities, including valuation allowances, be classified as noncurrent. This pronouncement is effective for fiscal years beginning after December 15, 2016, with early adoption permitted. We intend to adopt this pronouncement on January 1, 2017, and the adoption will not have a material impact on our financial position and/or results of operations.
In May 2014, an accounting pronouncement was issued by the FASB to clarify existing guidance on revenue recognition. This guidance includes the required steps to achieve the core principle that a company should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. This pronouncement is effective for fiscal years and interim periods beginning after December 15, 2017, with early adoption permitted. The guidance permits the use of one of two retrospective transition methods. We currently anticipate adopting the standard on January 1, 2018 using the modified retrospective method. We have commenced a process to evaluate the impact of the new pronouncement on our contracts, including identifying potential differences that would result from applying the requirements of the new guidance. In 2016, we have made progress in reviewing our various types of revenue arrangements and expect to be substantially complete with such review in the second quarter of 2017. We have also started drafting accounting policies and evaluating the new disclosure requirements on our business processes, controls and systems. As a result of the review performed to date, we do not anticipate that the adoption will have a material impact on our financial position and/or results of operations, particularly as it relates to revenues generated from long-term construction, service maintenance, and time and materials contracts. However, our initial conclusion may change as we finalize our assessment. We are still evaluating the impact of the new standard on our shop services operations, which currently recognize revenue related to the engineering, manufacturing and repair of shell and tube heat exchangers when the product is shipped and all other revenue recognition criteria have been met. The adoption of the new standard may accelerate the timing of revenue recognition for such shop services if we determine control is transferred to our customers over time instead of at a point in time.
NOTE 3 - ACQUISITIONS OF BUSINESSES

NOTE 8 - GOODWILL AND IDENTIFIABLE INTANGIBLE ASSETS
Goodwill at December 31, 20132016 and 20122015 was approximately $834.8979.6 million and $566.6843.2 million, respectively, and reflects the excess of cost over fair market value of net identifiable assets of companies acquired. Goodwill attributable to companies acquired in 20132016 and 2015 has been valued at $268.2$135.9 million. and $9.6 million, respectively. ASC Topic 805, “Business Combinations” (“ASC 805”) requires that all business combinations be accounted for using the acquisition method and that certain identifiable intangible assets acquired in a business combination be recognized as assets apart from goodwill. ASC Topic 350, “Intangibles-Goodwill and Other” (“ASC 350”) requires goodwill and other identifiable intangible assets with indefinite useful lives not be amortized, such as trade names, but instead must be tested at least annually for impairment (which we test each October 1, absent any impairment indicators) and be written down if impaired. ASC 350 requires that goodwill be allocated to its respective reporting unit and that identifiable intangible assets with finite lives be amortized over their useful lives. As of December 31, 20132016, approximately 46.1%39.3% of our goodwill related to our United States industrial services segment, approximately 27.4%25.0% of our goodwill related to our United States building services segment, approximately 26.0%23.1% of our goodwill related to our United States mechanical construction and facilities services segment and approximately 0.5%12.6% of our goodwill related to our United States electrical construction and facilities services segment.
We test for impairment of goodwill at the reporting unit level. Our reporting units are consistent with the reportable segments identified in Note 17, "Segment Information"“Segment Information”, of the notes to consolidated financial statements. In assessing whether our goodwill is impaired, we first qualitatively assess whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount using various factors. If after this assessment we are unable to determine that the fair value of a reporting unit exceeds the carrying amount, we proceed toutilize the two-step process as prescribed by ASC 350. The first step of this test compares the fair value of the reporting unit, determined based upon discounted estimated future cash flows, to the carrying amount, including goodwill. If the fair value exceeds the carrying amount, no further workanalysis is required and no impairment loss is recognized. If the carrying amount of the reporting unit exceeds the fair value, the goodwill of the reporting unit is potentially impaired and step two of the goodwill impairment test would need to be performed to measure the amount of an impairment loss, if any. In the second step, the impairment is computed by comparing the implied fair value of the reporting unit'sunit’s goodwill with the carrying amount of the goodwill. If the carrying amount of the reporting unit'sunit’s goodwill is greater than the implied fair value of its goodwill, an impairment loss in the amount of the excess is recognized and charged to operations.

amount of the excess is recognized and charged to operations. The weighted average cost of capital used in our annual testing for impairment as of October 1, 20132016 was 12.1%11.4%, 12.6%11.0% and 11.1%11.5% for our domestic construction segments, our United States building services segment and our United States industrial services segment, respectively. The perpetual growth rate used for our annual testing was 2.7% for all of our domestic segments. Unfavorable changes in these key assumptions may affect future testing results and cause us to fail step one of the goodwill impairment testing process. For example, keeping all other assumptions constant, a 50 basis point increase in the weighted average costs of capital would cause the estimated fair value of our United StatedStates industrial services segment to approach its carrying value. A 50 basis point increase in the weighted average costs of capital would not significantly reduce the excess of the estimated fair value compared to the carrying value for any of our other domestic segments. In addition, keeping all other assumptions constant, a 50 basis point reduction in the perpetual growth rate would not significantly reduce the excess of the estimated fair value compared to the carrying value for any of our domestic segments. For the years ended December 31, 2013, 20122016, 2015 and 2011,2014, no impairment of our goodwill was recognized.
We also test for the impairment of trade names that are not subject to amortization by calculating the fair value of such trade names using the “relief from royalty payments” methodology. This approach involves two steps: (a) estimating reasonable royalty rates for each trade name and (b) applying these royalty rates to a net revenue stream and discounting the resulting cash flows to determine fair value. This fair value is then compared with the carrying value of each trade name. If the carrying amount of the trade name is greater than the implied fair value of the trade name, an impairment in the amount of the excess is recognized and charged to operations. The annual impairment review of our trade names for the yearyears ended December 31, 20112016 and 2014 resulted in a $1.0$2.4 million and $1.5 million, respectively, of non-cash impairment chargecharges as a result of a change in the fair value of subsidiary trade names associated with certain prior acquisitions reported within our United States buildingmechanical construction and facilities services segment. This impairment primarily resulted from both lower forecasted revenues from,segment and lower operating margins at, specific companies within our United States building services segment. For the yearsyear ended December 31, 2013 and 2012, 2015, no impairment of our trade names was recognized.
In addition, we review for the impairment of other identifiable intangible assets that are being amortized whenever facts and circumstances indicate that their carrying values may not be fully recoverable. This test compares their carrying values to the undiscounted pre-tax cash flows expected to result from the use of the assets. If the assets are impaired, the assets are written down to their fair values, generally determined based on their future discounted cash flows. Based on facts and circumstances that indicated an impairment may exist, we performed an impairment review of certain of our other identifiable intangible assets for the year ended December 31, 2011. As a result of this review, we recognized a $2.8 million non-cash impairment charge as a result of a change in the fair value of customer relationships associated with certain prior acquisitions reported within our United States building services segment for the year ended December 31, 2011. For the years ended December 31, 20132016, 2015 and 2012,2014, no impairment of our other identifiable intangible assets was recognized.
Our development of the present value of future cash flow projections used in impairment testing is based upon assumptions and estimates by management from a review of our operating results, business plans, anticipated growth rates and margins and weighted average cost of capital, among others. Those assumptions and estimates can change in future periods, and other factors used in assessing fair value are outside the control of management, such as interest rates. There can be no assurances that our estimates and assumptions made for purposes of our goodwill and identifiable intangible asset impairment testing will prove to be accurate predictions of the future. If our assumptions regarding future business performance plans or anticipated growth rates and/or margins are not achieved, or there is a rise in interest rates, we may be required as we did in 2011, to record goodwill and/or identifiable intangible asset impairment charges in future periods.
During 2011, we recognized a $3.8 million non-cash impairment charge as discussed above. Of this amount, $2.8 million related to customer relationships and $1.0 million related to trade names. It is not possible at this time to determine if any such future impairment charge would result or, if it does, whether such a charge would be material.

NOTE 10 - FAIR VALUE MEASUREMENTS
We use a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy, which gives the highest priority to quoted prices in active markets, is comprised of the following three levels:
Level 1 – Unadjusted quoted market prices in active markets for identical assets and liabilities.
Level 2 – Observable inputs, other than Level 1 inputs. Level 2 inputs would typically include quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly.
Level 3 – Prices or valuations that require inputs that are both significant to the measurement and unobservable.

NOTE 10 - FAIR VALUE MEASUREMENTS - (Continued)

We believe that the carrying values of our financial instruments, which include accounts receivable and other financing commitments, approximate their fair values due primarily to their short-term maturities and low risk of counterparty default. The carrying value of our 2013debt associated with the 2016 Credit Agreement approximates theits fair value due to the variable rate on such debt.
 
NOTE 11 - INCOME TAXES    
Our 20132016 income tax provision from continuing operations was $75.3111.2 million compared to $95.4106.3 million for 20122015 and $76.8103.5 million for 20112014.

We file a consolidated federal income tax return including all of our U.S. subsidiaries. As of December 31, 20132016 and 20122015, the total valuation allowance on net deferred income tax assets was approximately $2.23.5 million and $2.50.8 million, respectively, primarily related to state and local net operating losses. The reason for the net decreaseincrease in the valuation allowance for 20122016 was related to the expirationuncertainty of net capital loss carryforwards, partially offset by state and localprojected future earnings required to realize the benefit of net operating loss carryforwards. At December 31, 2013, we had trading and capital lossescarryforwards for United Kingdom income tax purposes of approximately $34.7 million, which have no expiration date. Such losses are subject to review by the United Kingdom taxing authority. Realization of the deferred income tax assets is dependent on our generating sufficient taxable income. We believe that the deferred income tax assets will be realized through the future reversal of existing taxable temporary differences and projected future income.certain subsidiaries. Although realization is not assured, we believe it is more likely than not that the deferred income tax asset, net of the valuation allowance discussed above, will be realized. The amount of the deferred income tax asset considered realizable, however, could be reduced if estimates of future income are reduced.
At December 31, 2016, we had trading losses for United Kingdom income tax purposes of approximately $17.9 million, which have no expiration date. Such losses are subject to review by the United Kingdom taxing authority. Realization of the deferred income tax assets is dependent on our generating sufficient taxable income. We believe that the deferred income tax assets will be realized through projected future income.

Generally, our corporate employees and non-union employees of our United States subsidiaries are eligible to participate in this plan. Employees covered by collective bargaining agreements generally are not eligible to participate in this plan.
NOTE 14 - RETIREMENT PLANS
Defined Benefit Plans
Our United Kingdom subsidiary has a defined benefit pension plan covering all eligible employees (the “UK Plan”); however, no individual joining the company after October 31, 2001 may participate in the plan. On May 31, 2010, we curtailed the future accrual of benefits for active employees under this plan.
We account for our UK Plan and other defined benefit plans in accordance with ASC 715, “Compensation-Retirement Benefits” (“ASC 715”). ASC 715 requires that (a) the funded status, which is measured as the difference between the fair value of plan assets and the projected benefit obligations, be recorded in our balance sheet with a corresponding adjustment to accumulated other comprehensive income (loss) and (b) gains and losses for the differences between actuarial assumptions and actual results, and unrecognized service costs, be recognized through accumulated other comprehensive income (loss). These amounts will be subsequently recognized as net periodic pension cost.
The change in benefit obligations and assets of the UK Plan for the years ended December 31, 20132016 and 20122015 consisted of the following components (in thousands):

For 2013 and 2012, theThe annual rate of return on plan assets has been determined by modeling possible returns using the actuary'sactuary’s portfolio return calculator.calculator and the fair value of plan assets. This models the long term expected returns of the various asset classes held in the portfolio and allows fortakes into account the additional benefits of holding a diversified portfolio. The annual rate of return on plan assets for 2011 was based on the yield of risk-free bonds, plus an estimated equity-risk premium, at each year's measurement date. This annual rate approximates the historical annual return on plan assets and considers the expected asset allocation between equity and debt securities. For measurement purposes of the liability, the annual rates of inflation of covered pension benefits assumed for 20132016 and 20122015 were 2.3%2.2% and 2.0%, respectively.

Actuarial gains and losses are amortized using a corridor approach whereby cumulative gains and losses in excess of the greater of 10% of the pension benefit obligation or the fair value of plan assets are amortized over the average life expectancy of plan participants. The amortization period for 2016 was 27 years.
The reclassification adjustment, net of income taxes, for the UK Plan from Accumulatedaccumulated other comprehensive loss into net periodic pension cost for the years ended December 31, 2013, 20122016, 2015 and 20112014 was approximately $1.7 million, $2.0 million $1.9 million and $1.2$1.6 million, respectively, which was classified as a component of "Cost“Cost of sales"sales” and "Selling,“Selling, general and administrative expenses" onexpenses” in the Consolidated Statements of Operations.

In regards to the plan assets of our UK Plan, investment amounts have been allocated within the fair value hierarchy across all three levels.based on the nature of the investment. The characteristics of the assets that sit within each level are summarized as follows:
Level 1-This asset represents cash.
Level 2-These assets are a combination of the following:
(a)Assets that are not exchange traded but have a unit price that is based on the net asset value of the fund. The unit prices are not quoted but the underlying assets held by the fund are either:
(i)held in a variety of listed investments
(ii)held in UK treasury bonds or corporate bonds with the asset value being based on fixed income streams. Some of the underlying bonds are also listed on regulated markets.
It is the value of the underlying assets that have been used to calculate the unit price of the fund.

Multiemployer Plans
We participate in overapproximately 200 multiemployer pension plans (“MEPPs”) that provide retirement benefits to certain union employees in accordance with various collective bargaining agreements (“CBAs”). As one of many participating employers in these MEPPs, we are responsible with the other participating employers for any plan underfunding. Our contributions to a particular MEPP are established by the applicable CBAs; however, our required contributions may increase based on the funded status of an MEPP and legal requirements of the Pension Protection Act of 2006 (the “PPA”), which requires substantially underfunded MEPPs to implement a funding improvement plan (“FIP”) or a rehabilitation plan (“RP”) to improve their funded status. Factors that could impact the funded status of an MEPP include, without limitation, investment performance, changes in the participant demographics, decline in the number of contributing employers, changes in actuarial assumptions and the utilization of extended amortization provisions.
An FIP or RP requires a particular MEPP to adopt measures to correct its underfunding status. These measures may include, but are not limited to: (a) an increase in our contribution rate as a signatory to the applicable CBA, (b) a reallocation of the contributions already being made by participating employers for various benefits to individuals participating in the MEPP and/or (c) a reduction in the benefits to be paid to future and/or current retirees. In addition, the PPA requires that a 5% surcharge be levied on employer contributions for the first year commencing shortly after the date the employer receives notice that the MEPP is in critical status and a 10% surcharge on each succeeding year until a CBA is in place with terms and conditions consistent with the RP.
We could also be obligated to make payments to MEPPs if we either cease to have an obligation to contribute to the MEPP or significantly reduce our contributions to the MEPP because we reduce our number of employees who are covered by the relevant MEPP for various reasons, including, but not limited to, layoffs or closure of a subsidiary assuming the MEPP has unfunded vested benefits. The amount of such payments (known as a complete or partial withdrawal liability) would equal our proportionate share of the MEPPs'MEPPs’ unfunded vested benefits. We believe that certain of the MEPPs in which we participate may have unfunded vested benefits. Due to uncertainty regarding future factors that could trigger withdrawal liability, as well as the absence of specific information regarding the MEPP'sMEPP’s current financial situation, we are unable to determine (a) the amount and timing of any future withdrawal liability, if any, and (b) whether our participation in these MEPPs could have a material adverse impact on our financial position, results of operations or liquidity. We recorded a withdrawal liability of approximately $0.1 million for the year ended December 31, 2013. We did not record any withdrawal liability for the years ended December 31, 20122016, 2015 and 2011.2014.
The following table lists all domestic MEPPs to which our contributions exceeded $2.0 million in 20132016. Additionally, this table also lists all domestic MEPPs to which we contributed in 20132016 in excess of $0.5 million for MEPPs in the critical status, “red“red zone”, and $1.0 million in the endangered status, “orange or yellow zones”, as defined by the PPA (in thousands):

(1)The zone status represents the most recent available information for the respective MEPP, which may be 20122015 or earlier for the 20132016 year and 20112014 or earlier for the 20122015 year.
(2)This information was obtained from the respective plans'plan’s Form 5500 (“Forms”) for the most current available filing. These dates may not correspond with our fiscal year contributions. The above noted percentages of contributions are based upon disclosures contained in the plans' Form 5500 filing (“Forms”).plans’ Forms. Those Forms, among other things, disclose the names of individual participating employers whose annual contributions account for more than 5% of the aggregate annual amount contributed by all participating employers for a plan year. Accordingly, if the annual contribution of two or more of our subsidiaries each accounted for less than 5% of such contributions, but in the aggregate accounted for in excess of 5% of such contributions, that greater percentage is not available and accordingly is not disclosed.
(3)For these respective plans, a funding surcharge was currently in effect for 2013.2016.
The nature and diversity of our business may result in volatility in the amount of our contributions to a particular MEPP for any given period. That is because, in any given market, we could be working on a significant project and/or projects, which could result in an increase in our direct labor force and a corresponding increase in our contributions to the MEPP(s) dictated by the applicable CBA. When that particular project(s) finishes and is not replaced, the number of participants in the MEPP(s) who are employed by us would also decrease, as would our level of contributions to the particular MEPP(s). Additionally, the amount of contributions to a particular MEPP could also be affected by the terms of the CBA, which could require at a particular time, an increase in the contribution rate and/or surcharges. We have also acquired various companies since 2011, some of which participate in MEPPs, and as a result, our contributions have increased. As a result of acquisitions made in 2011, ourOur contributions to various MEPPs increased by $5.4 million for the year ended December 31, 2011. No additional contributions were made to MEPPs for the years ended December 31, 2013 and 2012,did not significantly increase as a result of acquisitions made in each respective year since the acquired companies were not parties to any MEPPs.2014.
We also participate in two MEPPs that are located within the United Kingdom for which we have contributed $0.30.2 million for each of the years ended December 31, 20132016, , 20122015 and 20112014. The information that we have obtained relating to these plans is not as readily available and/or as comparable as the information that has been ascertained in the United States. Based upon the most recently available information, one of the plans is 100% funded, and the other plan is between 65% and less than 65%80% funded. A recovery plan has been put in place for the plan that is less than 65%80% funded, which requires higher contribution amounts to be paid by our UK operations.
Additionally, we contribute to certain multiemployer plans that provide post retirement benefits such as health and welfare benefits and/or defined contribution/annuity plans, among others. Our contributions to these plans approximated $93.5130.5 million, $89.9108.1 million and $76.598.3 million for the years ended December 31, 20132016, 20122015 and 20112014, respectively. Acquisitions made in 2011 accounted for an increase in ourOur contributions to these types of plans of $2.5 million for the year ended December 31, 2011. No additional contributions were made to other post retirement benefit plans for the years ended December 31, 2013 and 2012,did not significantly increase as a result of acquisitions made in each respective year since the acquired companies were not parties to any of these types of plans.2014. The amount of contributions to these plans is also subject for the most part to the factors discussed above in conjunction with the MEPPs.
Defined Contribution Plans
We have defined contribution retirement and savings plans that cover eligible employees in the United States. Contributions to these plans are based on a percentage of the employee'semployee’s base compensation. The expenses recognized for the years endedDecember 31, 2016, 2015 and 2014 for these plans were $26.8 million, $26.5 million and $25.3 million, respectively. At our discretion and subject to applicable plan documents, we may make additional supplemental matching contributions to one of our defined contribution retirement and savings plans. The expenses recognized related to additional supplemental matching for the years ended December 31, 2016, 2015 and 2014 were $5.4 million, $4.8 million and $4.3 million, respectively.

December 31, 2013, 2012 and 2011 for these plans were $22.6 million, $20.7 million and $12.8 million, respectively. The increase in 2012 compared to 2011 was primarily attributable to an increase in matching contributions for one of these plans. At our discretion, we may make additional supplemental matching contributions to a defined contribution retirement and savings plan. The expenses recognized related to additional supplemental matching for the years ended December 31, 2013, 2012 and 2011 were $4.0 million, $3.6 million and $3.0 million, respectively.
Our United Kingdom subsidiary has defined contribution retirement plans. The expense recognized for the years ended December 31, 20132016, 20122015 and 20112014 was $5.03.6 million, $5.74.0 million and $6.04.5 million, respectively.

Contractual Guarantees
We have agreements with our executive officers and certain other key management personnel providing for severance benefits for such employees upon termination of their employment under certain circumstances.
From time to time in the ordinary course of business, we guarantee obligations of our subsidiaries under certain contracts. Generally, we are liable under such an arrangement only if our subsidiary fails to perform its obligations under the contract. Historically, we have not incurred any substantial liabilities as a consequence of these guarantees.
The terms of our construction contracts frequently require that we obtain from surety companies (“Surety Companies”) and provide to our customers payment and performance bonds (“Surety Bonds”) as a condition to the award of such contracts. The Surety Bonds secure our payment and performance obligations under such contracts, and we have agreed to indemnify the Surety Companies for amounts, if any, paid by them in respect of Surety Bonds issued on our behalf. In addition, at the request of labor unions representing certain of our employees, Surety Bonds are sometimes provided to secure obligations for wages and benefits payable to or for such employees. Public sector contracts require Surety Bonds more frequently than private sector contracts, and accordingly, our bonding requirements typically increase as the amount of public sector work increases. As of December 31, 20132016, based on our percentage-of-completion of our projects covered by Surety Bonds, our aggregate estimated exposure, had there been

defaults on all our then existing contractual obligations, was approximately $0.81.1 billion. The Surety Bonds are issued by Surety Companies in return for premiums, which vary depending on the size and type of bond.
We are subject to regulation with respect to the handling of certain materials used in construction, which are classified as hazardous or toxic by federal, state and local agencies. Our practice is to avoid participation in projects principally involving the remediation or removal of such materials. However, when remediation is required as part of our contract performance, we believe

Government Contracts
As a government contractor, we are subject to U.S. government audits and investigations relating to our operations, fines, penalties and compensatory and treble damages, and possible suspension or debarment from doing business with the government. Based on currently available information, we believe the outcome of ongoing government disputes and investigations will not have a material impact on our financial position, results of operations or liquidity.

Legal Matters
One of our subsidiaries was a subcontractor to a mechanical contractor ("(“Mechanical Contractor"Contractor”) on a construction project where an explosion occurred.occurred in 2010. An investigation of the matter could not determine who was responsible for the explosion. As a result of the explosion, lawsuits have been commenced against various parties, but, to date, no lawsuits have been commenced against our subsidiary with respect to personal injury or damage to property as a consequence of the explosion. However, the Mechanical Contractor has asserted claims, in the context of an arbitration proceeding against our subsidiary, alleging that our subsidiary is responsible for a portion of the damages for which the Mechanical Contractor may be liable as a result of: (a) losses asserted by the owner of the project and/or the owner's general contractor because of delays in completion of the project and damages to its property, (b) personal injury suffered by individuals as a result of the explosion and (c)(b) the Mechanical Contractor'sContractor’s legal fees and associated management costs in defending against any and all such claims. The Mechanical Contractor previously asserted claims under the Connecticut and Massachusetts Unfair and Deceptive Practices Acts, but such claims were recently withdrawn. The general contractor (as assignee of the Mechanical Contractor) on the construction project, and for whom the Mechanical Contractor worked, has alleged that our subsidiary is responsible for losses asserted by the owner of the project and/or the general contractor because of delays in completion of the project and for damages to the owner’s property. We believe, and have been advised by counsel, that we have a number of meritorious defenses to all such matters. We believe that the ultimate outcome of such matters will not have a material adverse effect on our consolidated financial position, results of operations or liquidity. Notwithstanding our assessment of the final impact of this matter, we are not able to estimate with any certainty the amount of loss, if any, which would be associated with an adverse resolution.
One of our subsidiaries, USM, Inc. ("USM"), doing business in California provides, among other things, janitorial services to its customers by having those services performed by independent janitorial companies. USM and one of its customers, which owns retail stores (the “Customer”), are co-defendants in a federal class action lawsuit brought by employees of two of USM’s California local janitorial contractors. The action was commenced on September 5, 2013 in a Superior Court of California and was removed by USM on November 22, 2013 to the United States District Court for the Northern District of California. The employees allege in their complaint, among other things, that USM and the Customer violated a California statute that prohibits USM from entering into a contract with a janitorial contractor when it knows or should know that the contract does not include funds sufficient to allow the janitorial contractor to comply with all local, state and federal laws or regulations governing the labor or services to be provided. The employees have asserted that the amounts USM pays to its janitorial contractors are insufficient to allow those janitorial contractors to meet their obligations regarding, among other things, wages due for all hours their employees worked, minimum wages, overtime pay and meal and rest breaks. These employees seek to represent not only themselves, but also all other individuals who provided janitorial services at the Customer’s stores in California during the relevant four year time period. We do not believe USM or the Customer has violated the California statute or that the employees may bring the action as a class action on behalf of other employees of janitorial companies with whom USM contracted for the provision of janitorial services to the Customer. However, if the pending lawsuit is certified as a class action and USM is found to have violated the California statute, USM might have to pay significant damages and might be subject to similar lawsuits regarding the provision of janitorial services to its other customers in California. The plaintiffs seek a declaratory judgment that USM has violated the California statute, monetary damages, including all unpaid wages and thereon, restitution for unpaid wages, and an award of attorney fees and costs.
We are involved in several other proceedings in which damages and claims have been asserted against us. Other potential claims may exist that have not yet been asserted against us. We believe that we have a number of valid defenses to such proceedings and claims and intend to vigorously defend ourselves. We do not believe that any such matters will have a material adverse effect on our financial position, results of operations or liquidity. Litigation is subject to many uncertainties and the outcome of litigation is not predictable with assurance. It is possible that some litigation matters for which reservesliabilities have not been establishedrecorded could be decided unfavorably to us, and that any such unfavorable decisions could have a material adverse effect on our financial position, results of operations or liquidity.

During 2016, we incurred $19.4 million of losses on a transportation project within our United States electrical construction and facilities services segment as a result of productivity issues attributable to unfavorable job-site conditions. In addition, within the United States mechanical construction and facilities services segment, we incurred $18.3 million of losses on a project at a process facility as a result of a contract dispute with our customer and $9.6 million of losses on an institutional project due to project delays and unfavorable job-site conditions. The results of our United States mechanical construction and facilities services segment included revenues of $12.1 million recognized during 2015 as a result of the settlement of a claim on an institutional project located in the Southeastern region of the United States. Our United Kingdom building services segment recognized income of $4.8 million during 2014, which has been recorded as a reduction of "Cost of sales" in the Consolidated Statements of Operations for the year ended December 31, 2014, as a result of a reduction in the estimate of certain accrued contract costs that were no longer expected to be incurred within its building services operations.

Report of Independent Registered Public Accounting Firm
The Board of Directors and ShareholdersStockholders of EMCOR Group, Inc.: and subsidiaries:
We have audited EMCOR Group, Inc. and subsidiaries' (the “Company”)subsidiaries’ internal control over financial reporting as of December 31, 2013,2016, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992(2013 Framework) (the COSO criteria). The Company'sEMCOR Group, Inc. and subsidiaries’ 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'sManagement’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company'sCompany’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'scompany’s internal control over financial reporting is a process designed 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'scompany’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'scompany’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

As indicated in the accompanying Management’s Report on Internal Control over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of RepconStrickland, Inc. ("RSI"), which is included in the 2013 consolidated financial statements of the Company and constituted $560.0 million, or 16.2%, of the Company's total assets as of December 31, 2013 and $123.6 million, or 1.9%, of the Company's revenues for the year then ended. Our audit of internal control over financial reporting of the Company also did not include an evaluation of the internal control over financial reporting of RSI.
In our opinion, the CompanyEMCOR Group, Inc. and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013,2016, based on the COSO criteria.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of the CompanyEMCOR Group, Inc. and subsidiaries as of December 31, 20132016 and 2012,2015, and the related consolidated statements of operations, comprehensive income, equity and cash flows for each of the three years in the period ended December 31, 2013 of the Company2016 and our report dated February 25, 201423, 2017 expressed an unqualified opinion thereon.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE
Not applicable.
ITEM 9A. CONTROLS AND PROCEDURES
Based on an evaluation of our disclosure controls and procedures (as required by Rules 13a-15(b) of the Securities Exchange Act of 1934), our President and Chief Executive Officer, Anthony J. Guzzi, and our Executive Vice President and Chief Financial Officer, Mark A. Pompa, have concluded that our disclosure controls and procedures (as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934) are effective as of the end of the period covered by this report.
Management'sManagement’s Report on Internal Control over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities and Exchange Act of 1934). Our internal control over financial reporting is a process designed with the participation of our principal executive officer and principal financial officer or persons performing similar functions to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our financial statements for external reporting purposes in accordance with U.S. generally accepted accounting principles.
Our internal control over financial reporting includes policies and procedures that: (a) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect our transactions and dispositions of assets, (b) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and Board of Directors and (c) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.
Because of its inherent limitations, our disclosure controls and procedures may not prevent or detect misstatements. A control system, no matter how well conceived and operated, can only provide reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.
In July 2013, EMCOR acquired RepconStrickland, Inc. ("RSI"). Since EMCOR has not yet fully incorporated the internal controls and procedures of RSI into EMCOR's internal control over financial reporting as of December 31, 2013, management excluded this business from its assessment of the effectiveness of internal control over financial reporting as of December 31, 2013. RSI accounted for $560.0 million, or 16.2%, of EMCOR's total assets as of December 31, 2013 and $123.6 million of revenues, or 1.9%, of EMCOR's total revenues for the year then ended.
As of December 31, 2013,2016, our management conducted an evaluation of the effectiveness of our internal control over financial reporting with the exception of the previously mentioned RSI acquisition, based on the framework established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”).Commission. Based on this evaluation, management has determined that EMCOR'sEMCOR’s internal control over financial reporting is effective as of December 31, 2013.2016.
The effectiveness of our internal control over financial reporting as of December 31, 20132016 has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in its report appearing in this Annual Report on Form 10-K, which such report expressed an unqualified opinion on the effectiveness of our internal control over financial reporting as of December 31, 2013.2016.
Changes in Internal Control over Financial Reporting
In addition, our management with the participation of our principal executive officer and principal financial officer or persons performing similar functions has determined that no change in our internal control over financial reporting (as that term is defined in Rules 13(a)-15(f) and 15(d)-15(f) of the Securities Exchange Act of 1934) occurred during the fourth quarter of our fiscal year ended December 31, 20132016 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting aside from the previously mentioned acquisition of RSI. As part of its ongoing integration activities, EMCOR is continuing to incorporate its controls and procedures into RSI..
