PART I

The terms “Comfort Systems,” “we,” “us,” or “the Company” refer to Comfort Systems USA, Inc. or Comfort Systems USA, Inc. and its consolidated subsidiaries, as appropriate in the context.

ITEM 1. Business

Comfort Systems USA, Inc., a Delaware corporation, provides comprehensive heating, ventilation and air conditioning (“HVAC”) installation, maintenance, repair and replacement services within the mechanical services industry in 49 cities and 55 locations throughout the United States.

We operate primarily in the commercial, industrial and institutional HVAC markets, and perform most of our services within office buildings, retail centers, apartment complexes, manufacturing plants, and healthcare, education and government facilities. In addition to standard HVAC services, we provide specialized applications such as building automation control systems, fire protection, process cooling, electronic monitoring and process piping. Certain locations also perform related activities such as electrical service and plumbing. Approximately 98% of our consolidated 2005 revenues were derived from commercial, industrial and institutional customers with approximately 56% of the revenues attributable to installation services in newly constructed facilities and 44% attributable to maintenance, repair and replacement services. Our consolidated 2005 revenues were derived from the following service activities, all of which are in the mechanical services industry, the single industry segment we serve:

Service Activity	Percentage of Revenue
HVAC		75
Plumbing		16
Building Automation Control Systems		4
Other		5
Total		100	%

We were originally formed in 1997 through an initial public offering, or IPO, and simultaneous acquisition of 12 companies engaged in our business. From the time we completed our IPO through December 1999, we acquired 107 HVAC and complementary businesses, of which 26 were “tuck-in” operations that were integrated upon acquisition with existing operations. From 2000 through 2004 we did not acquire any additional companies but rather shifted our strategy from an emphasis on acquisition-based growth to a focus on improving the performance of our existing operations. During that time, we sold or ceased operations at 35 companies and consolidated another 13 companies into other operations.

In January 2005 we acquired a business in New England. During 2005, we sold or ceased operations at five of our operating companies and consolidated one company into other operations. Today we have 40 operating units.

Our Internet address is http://www.comfortsystemsusa.com. We make available free of charge on or through our website our annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act as soon as reasonably practicable after we electronically file such material with, or furnish it to, the Securities and Exchange Commission, or the Commission. Our website also includes our code of ethics, titled “Corporate Compliance Policy: Standards and Procedures Regarding Business Practices,” together with other governance materials including our corporate governance guidelines and our Board committee charters. Printed versions of our code of ethics and our corporate governance guidelines may be obtained upon written request to our Corporate Compliance Officer at the Company’s headquarters address.

Industry Overview

We believe that the commercial, industrial, and institutional HVAC industry generates annual revenues in excess of $40 billion. HVAC systems are necessary to virtually all commercial, industrial and institutional buildings as well as homes. Because most buildings are sealed, HVAC systems provide the primary method of circulating fresh air in such buildings. In many instances, replacing an aging system with a modern, energy-efficient HVAC system significantly reduces a building’s operating costs and improves air quality and HVAC system effectiveness. Older commercial, industrial and institutional facilities often have poor air quality as well as inadequate air conditioning, and older HVAC systems result in significantly higher energy costs than do modern systems. These factors cause many facility owners to consider replacing older systems before the end of their functioning lives.

Many factors positively affect HVAC industry growth, particularly (i) population growth, which has increased the need for commercial, industrial and institutional space, (ii) an aging installed base of buildings and HVAC equipment, (iii) increasing sophistication, complexity, and efficiency of HVAC systems, (iv) growing emphasis on indoor air quality, and (v) reduction or elimination of the refrigerants commonly used in older HVAC systems. We believe these factors should increase demand for the reconfiguration or replacement of existing HVAC systems and may also mitigate, to some extent, the effect on the HVAC industry of the cyclicality inherent in the traditional construction industry.

The HVAC industry can be broadly divided into two service functions:

· installation in newly constructed facilities, which provided approximately 56% of our revenues in 2005, and

· maintenance, repair and replacement, which provided the remaining 44% of our 2005 revenues.

Installation Services. Installation services consist of “design and build” and “plan and spec” projects. In “design and build” projects, the commercial HVAC firm is responsible for designing, engineering and installing a cost-effective, energy-efficient system customized to the specific needs of the building owner. Costs and other project terms are normally negotiated between the building owner or its representative and the HVAC firm. Firms that specialize in “design and build” projects generally have specially-trained HVAC engineers, CAD/CAM design systems and in-house sheet metal and prefabrication capabilities. These firms use a consultative approach with customers and tend to develop long-term relationships with building owners and developers, general contractors, architects, consulting engineers and property managers. “Plan and spec” installation refers to projects in which a third-party architect or consulting engineer designs the HVAC systems and the installation project is “put out for bid.” We believe that “plan and spec” projects usually take longer to complete than “design and build” projects because the system

design and installation process generally are not integrated, thus resulting in more frequent adjustments to the technical specifications of the project and corresponding changes in work requirements and schedules. These adjustments can occur during the bid process or during the project itself, in either case adding weeks or months to the project schedule. Furthermore, in “plan and spec” projects, the HVAC firm is not responsible for project design and other parties must also approve any changes, thereby increasing overall project time and cost.

Maintenance, Repair and Replacement Services. These services include maintaining, repairing, replacing, reconfiguring and monitoring previously installed HVAC systems and building automation controls. The growth and aging of the installed base of HVAC systems and the demand for more efficient and sophisticated systems and building automation controls have fueled growth in this service line. The increasing complexity of these HVAC systems is leading many commercial, industrial and institutional building owners and property managers to increase attention to maintenance and to outsource maintenance and repair, often through service agreements with HVAC service providers. In addition, further restrictions have been placed on the use of certain types of refrigerants used in HVAC systems, which, along with indoor air quality concerns, may increase demand for the reconfiguration and replacement of existing HVAC systems. State-of-the-art control and monitoring systems feature electronic sensors and microprocessors. These systems require specialized training to install, maintain and repair, and the typical building engineer employed directly by a building owner or manager has not received this training. Increasingly, HVAC systems in commercial, industrial and institutional buildings are being remotely monitored through PC-based communications systems to improve energy efficiency and expedite problem diagnosis and correction, thereby allowing us to provide maintenance and repair services at a lower cost.

Strategy

We focus on strengthening operating competencies and on increasing profit margins. The key elements of our operating strategy are:

Achieve Excellence in Core Competencies. We have identified six core competencies, which we believe are critical to attracting and retaining customers, increasing operating income and cash flow and creating additional employment opportunities. The six core competencies are: (i) customer cultivation and intimacy, (ii) design and build expertise, (iii) estimating, (iv) job costing and job measurements, (v) safety, and (vi) service capability.

Achieve Operating Efficiencies. We think we can achieve operating efficiencies and cost savings through purchasing economies, adopting “best practices” operating programs, and focusing on job management to deliver services in a cost-effective and efficient manner. We have placed great emphasis on improving the “job loop” at our locations—qualifying, estimating, pricing and executing projects effectively and efficiently, then promptly assessing project experience for applicability to current and future projects. We also use our combined purchasing to gain volume discounts on products and services such as HVAC components, raw materials, services, vehicles, bonding, insurance and employee benefits.

Attract, Retain and Invest in our Employees. We seek to attract and retain quality employees by providing them an enhanced career path from working for a larger company, the opportunity to realize a more stable income and attractive benefits packages. Over the preceding two years we have substantially increased our investment in training, including programs for project managers, service managers, and more recently, leadership and development of key managers and leaders. We believe these programs can lead to significantly increased efficiency and growth.

Focus on Commercial, Industrial and Institutional Markets. We primarily focus on the commercial, industrial and institutional markets, with particular emphasis on “design and build” installation services, and on maintenance, repair and replacement services. We believe that the commercial, industrial, and

institutional HVAC markets are attractive because of their growth opportunities, large and diverse customer base, reduced weather exposure as compared to residential markets, attractive margins and potential for long-term relationships with building owners, property managers, general contractors and architects. Approximately 98% of our consolidated 2005 revenues were derived from commercial and industrial customers.

Maintain a Diverse Customer, Geographic and Project Base. We have what we believe is a well-diversified distribution of revenues across end-use sectors that reduces our exposure to negative developments in any given sector. We also believe we have a reasonable degree of geographical diversification, again reducing our exposure to negative developments in any given region. Our distribution of revenues in 2005 by end-use sector was as follows:

Multi-Family	16	%
Manufacturing	12	%
Office Buildings	11	%
Healthcare	13	%
Schools	11	%
Government	8	%
Retail	8	%
Distribution	2	%
Residential	2	%
Hotels	3	%
Banks	1	%
Other	13	%
Total	100	%

Approximately 85% of our revenues are earned on a project basis for installation of HVAC systems in newly constructed facilities or for replacement of HVAC systems in existing facilities. As of December 31, 2005, we had 4,642 projects in process with an aggregate contract value of approximately $1,391.3 million. Our average project takes three to six months to complete, with an average contract price of approximately $300,000. This relatively small average project size, when taken together with the approximately 15% of our revenues derived from maintenance and service, provides us with what we believe is a reasonably broad base of work for a company involved in the construction services sector. Projects with contract prices of $5 million or less accounted for $1,083.4 million, or 78%, of aggregate contract value of projects in process at December 31, 2005. A stratification of projects in progress as of December 31, 2005, by contract price is as follows:

Contract Price of Project	No. of Projects		Aggregate Contract Price Value (millions)
Under $1 million		4,427		$	684.8
$1 million - $5 million		177		398.6
$5 million - $10 million		29		185.1
$10 million - $15 million		8		100.4
$15 million - $25 million		1		22.4
Total		4,642		$	1,391.3

Leveraging Resources and Service Capabilities. We believe significant operating efficiencies can be achieved by leveraging resources among our operating locations. For example, we have shifted certain prefabrication activities into centralized locations thereby increasing asset utilization in these centralized locations and redirecting prefabrication employees into other operational areas. We also allocate our engineering, field and supervisory labor from one operation to another to more fully use our employee

base, meet our customers’ needs, and share expertise. We believe we have realized scale benefits from combining purchasing, insurance, benefits, bonding, and financing activities across our operations. We also believe larger regional and national commercial, industrial, and institutional entities can benefit from consolidating their HVAC needs with service companies that are capable of providing those services regionally or nationally. In response to this opportunity, we operate a national call center to dispatch technicians to regional and national sites requiring service and use web-based proprietary information systems to maintain information on the customer’s sites and equipment.

Seek Growth Through Expansion and Measured Acquisitions. We believe that we can increase our operating income by opportunistically entering new markets or service lines through expansion and acquisition. We have based such expansion on existing customers, relationships or expertise, and expect to selectively pursue such opportunities in the future. When we find opportunities to acquire businesses that have attractive valuations and meet other criteria involving financial, operational, management, geographic and legal due diligence considerations, we will consider such transactions. Under our current credit facility, certain acquisitions must be approved in advance by our bank group.

Operations and Services Provided

We provide a wide range of installation, maintenance, repair and replacement services for HVAC and related systems in commercial, industrial and institutional properties. We manage our locations on a decentralized basis, with local management maintaining responsibility for day-to-day operating decisions. Our local management is augmented by regional leadership that focuses on core business competencies, regional financial performance, cooperation and coordination between locations, implementing best practices, and on major corporate initiatives. In addition to senior management, local personnel generally include design engineers, sales personnel, customer service personnel, installation and service technicians, sheet metal and prefabrication technicians, estimators and administrative personnel. We have centralized certain administrative functions such as insurance, employee benefits, training, safety programs, marketing and cash management to enable our local operating management to focus on pursuing new business opportunities and improving operating efficiencies. We also combine certain back office and administrative functions at various locations.

Installation Services. Our installation business related to newly constructed facilities, which comprised approximately 56% of our consolidated 2005 revenues, involves the design, engineering, integration, installation and start-up of HVAC, building automation controls and related systems. We provide “design and build” and “plan and spec” installation services for office buildings, retail centers, apartment complexes, manufacturing plants, health care, education and government facilities and other commercial, industrial, and institutional facilities. In a “design and build” installation, working with the customer, we determine the needed capacity and energy efficiency of the HVAC system that best suits the proposed facility. We then estimate the amount of time, labor, materials and equipment needed to build the specified system. The final design, terms, price and timing of the project are then negotiated with the customer or its representatives, after which any necessary modifications are made to the system plan. In “plan and spec” installation, we participate in a bid process to provide labor, equipment, materials and installation based on plans and engineering specifications provided by a customer, general contractor or consulting engineer.

Once an agreement has been reached, we order the necessary materials and equipment for delivery to meet the project schedule. In many instances, we fabricate the ductwork and piping and assemble certain components for the system based on the mechanical drawing specifications, eliminating the need to subcontract ductwork or piping fabrication. Then we install the system at the project site, working closely with the general contractor. Our average project takes three to six months to complete, with an average contract price of approximately $300,000. We also perform larger project work, with 215 contracts in progress at December 31, 2005 with contract prices in excess of $1 million. Our largest project currently in

progress has a contract price of $22.4 million. Project contracts typically provide for periodic billings to the customer as we meet progress milestones or incur cost on the project. Project contracts in our industry also frequently allow for a small portion of progress billings or contract price to be withheld by the customer until after we have completed the work, typically for six months. Amounts withheld under this practice are known as retention or retainage.

We also install process cooling systems and building automation controls and monitoring systems. Process cooling systems are used primarily in industrial facilities to provide heating and/or cooling to precise temperature and climate standards for products being manufactured and for the manufacturing equipment. Building automation control systems are used in HVAC and process cooling systems to maintain pre-established temperature or climate standards for commercial or industrial facilities. Building automation control systems are capable not only of controlling a facility’s entire HVAC system, often on a room-by-room basis, but can also be programmed to integrate energy management, and monitoring for purposes of security, fire, card key access, lighting and other building systems. This monitoring can be performed on-site or remotely through a PC-based communications system. The monitoring system communicates an exception when a system is operating outside pre-established parameters. Diagnosis of potential problems and remedial adjustments can often be performed remotely from system monitoring terminals.

Maintenance, Repair and Replacement Services. Our maintenance, repair and replacement services comprised approximately 44% of our consolidated 2005 revenues and include the maintenance, repair, replacement, reconfiguration and monitoring of HVAC systems and industrial process piping. Approximately two-thirds of our maintenance, repair and replacement revenues were derived from replacing and reconfiguring existing HVAC systems for commercial, industrial, and institutional customers. Replacement and reconfiguration are usually performed on a project basis and often use consultative expertise similar to that provided in the “design and build” installation market.

Maintenance and repair services are provided either in response to service calls or under a service agreement. Service calls are coordinated by customer service representatives or dispatchers that use computer and communication technology to process orders, arrange service calls, communicate with customers, dispatch technicians and invoice customers. Service technicians work from service vehicles equipped with commonly used parts, supplies and tools to complete a variety of jobs. Commercial, industrial and institutional service agreements usually have terms of one to three years, with automatic annual renewals, and typically with 30-60 day cancellation notice periods. We also provide remote monitoring of temperature, pressure, humidity and air flow for HVAC systems. If the system is not operating within the specifications set forth by the customer and cannot be remotely adjusted, a service crew is dispatched to analyze and repair the system.

Sources of Supply

The raw materials and components we use include HVAC system components, ductwork, steel, sheet metal and copper tubing and piping. These raw materials and components are generally available from a variety of domestic or foreign suppliers at competitive prices. Delivery times are typically short for most raw materials and standard components, but during periods of peak demand, may extend to one month or more. Over the last two years, many steel, iron and copper products, in particular, have experienced significant price fluctuation and some constrained availability. We estimate that direct purchase of these commodities comprises between 10% and 15% of our average project cost. We began taking steps early in 2004 to reduce commodity cost exposure. Among these steps were early buying of commodities for particular projects, or for general inventory, as well as including escalation and escape provisions in project bids and contracts wherever possible. The negative effects of unrecovered commodity cost inflation in our project results have been modest, and are reviewed further in Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” later in this report.

Chillers for large units typically have the longest delivery time and generally have lead times of up to six months. The major components of commercial HVAC systems are compressors and chillers that are manufactured primarily by York, Carrier, Trane and Lennox. The major suppliers of building automation control systems are Honeywell, Johnson Controls, Siemens, York, Automated Logic, Novar and Andover Control Corporation. We do not have any significant contracts guaranteeing us a supply of raw materials or components.

We administer a portion of our procurement activities with Emcor Group, a larger publicly-held provider of electrical and mechanical services and facilities management. This coordination includes contractual arrangements with Emcor under which certain Emcor employees provide procurement management services to us.

Sales and Marketing

We have a diverse customer base, with no single customer accounting for more than 3% of consolidated 2005 revenues. Management and a dedicated sales force are responsible for developing and maintaining successful long-term relationships with key customers. Customers generally include building owners and developers and property managers, as well as general contractors, architects and consulting engineers. We intend to continue our emphasis on developing and maintaining long-term relationships with our customers by providing superior, high-quality service in a professional manner. We believe we can continue to leverage the diverse technical and marketing strengths at individual locations to expand the services offered in other local markets. With respect to multi-location service opportunities, we maintain a national sales force in our National Accounts group.

Employees

As of December 31, 2005, we had 5,955 employees. We have collective bargaining agreements covering approximately 83 employees. We have not experienced and do not expect any significant strikes or work stoppages and believe our relations with employees covered by collective bargaining agreements are good.

Recruiting, Training and Safety

Our continued success depends, in part, on our ability to continue to attract, retain and motivate qualified engineers, service technicians, field supervisors and project managers. We believe our success in retaining qualified employees will be based on the quality of our recruiting, training, compensation, employee benefits programs and opportunities for advancement. We provide on-the-job training, technical training, apprenticeship programs, attractive benefit packages and career advancement opportunities within our company.

We have established comprehensive safety programs throughout our operations to ensure that all technicians comply with safety standards we have established and that are established under federal, state and local laws and regulations. Additionally, we have implemented a “best practices” safety program throughout our operations, which provides employees with incentives to improve safety performance and decrease workplace accidents. Regional safety directors establish safety programs and benchmarking to improve safety within their region. Finally, our employment screening process seeks to determine that prospective employees have requisite skills, sufficient background references and acceptable driving records, if applicable. Our rate of incidents recordable under the standards of the Occupational Safety and Health Administration per 100 employees per year, also known as the OSHA recordable rate, was 3.88 during 2005. This level was 52% better than the most recently published OSHA rate for our industry. We have improved our OSHA recordable rate every year since we first began tracking it company-wide seven years ago.

Risk Management, Insurance and Litigation

The primary risks in our operations are bodily injury, property damage and workers’ compensation injuries. We retain the risk for worker’s compensation, employer’s liability, auto liability, general liability and employee group health claims resulting from uninsured deductibles per incident or occurrence. Because we have very large deductibles, the vast majority of our claims are paid by us, so as a practical matter we self-insure the great majority of these risks. Losses up to such per-incident deductible amounts are estimated and accrued based upon known facts, historical trends and industry averages utilizing the assistance of an actuary to project the extent of these obligations.

We are subject to certain claims and lawsuits arising in the normal course of business. We maintain various insurance coverages to minimize financial risk associated with these claims. We have estimated and provided accruals for probable losses and related legal fees associated with certain of our litigation in our consolidated financial statements. While we cannot predict the outcome of these proceedings, in our opinion and based on reports of counsel, any liability arising from these matters individually and in the aggregate will not have a material effect on our operating results or financial condition, after giving effect to provisions already recorded.

In addition to the matters described above, we are defending a dispute arising out of an alleged delay related to a multi-family construction project. If we are not successful in this dispute, it could have a material adverse effect on us. However, management believes the likelihood of an adverse result of this magnitude is remote, and management believes our accruals relating to the matter appropriately reflect a probable outcome.

We typically warrant labor for the first year after installation on new HVAC systems and pass through to the customer manufacturers’ warranties on equipment. We generally warrant labor for 30 days after servicing of existing HVAC systems. We do not expect warranty claims to have a material adverse effect on our financial position or results of operations.

Competition

The HVAC industry is highly competitive and consists of thousands of local and regional companies. We believe that purchasing decisions in the commercial, industrial and institutional markets are based on (i) competitive price, (ii) long-term customer relationships, (iii) quality, timeliness and reliability of services provided, (iv) an organization’s perceived stability based on years in business, financial strength, and access to bonding, (v) range of services provided, and (vi) scale of operation. To improve our competitive position we focus on both the consultative “design and build” installation market and the maintenance, repair and replacement market to promote first the development and then the strengthening of long-term customer relationships. In addition, we believe our ability to provide multi-location coverage, access to project financing and specialized technical skills for facilities owners gives us a strategic advantage over smaller competitors who may be unable to provide these services to customers at a competitive price.

We believe that we are larger than most of our competitors, which are generally small, owner-operated companies that typically operate in a limited geographic area. However, there are divisions of larger contracting companies, utilities and HVAC equipment manufacturers that provide HVAC services in some of the same service lines and geographic areas we serve. Some of these competitors and potential competitors have greater financial resources than we do to finance development opportunities and support their operations. We believe our smaller competitors generally compete with us based on price and their long-term relationships with local customers. Our larger competitors compete with us on those factors but may also provide attractive financing and comprehensive service and product packages.

Vehicles

We operate a fleet of various owned or leased service trucks, vans and support vehicles. We believe these vehicles generally are well maintained and sufficient for our current operations.

Governmental Regulation and Environmental Matters

Our operations are subject to various federal, state and local laws and regulations, including: (i) licensing requirements applicable to engineering, construction and service technicians, (ii) building and HVAC codes and zoning ordinances, (iii) regulations relating to consumer protection, including those governing residential service agreements, and (iv) regulations relating to worker safety and protection of the environment. We believe we have all required licenses to conduct our operations and are in substantial compliance with applicable regulatory requirements. If we fail to comply with applicable regulations we could be subject to substantial fines or revocation of our operating licenses.

Many state and local regulations governing the HVAC services trades require individuals to hold permits and licenses. In some cases, a required permit or license held by a single individual may be sufficient to authorize specified activities for all of our service technicians who work in the state or county that issued the permit or license. We seek to ensure that, where possible, we have two employees who hold any such permits or licenses that may be material to our operations in a particular geographic region.

Our operations are subject to the federal Clean Air Act, as amended, which governs air emissions and imposes specific requirements on the use and handling of chlorofluorocarbons, or CFCs, and certain other refrigerants. Clean Air Act regulations require the certification of service technicians involved in the service or repair of equipment containing these refrigerants and also regulate the containment and recycling of these refrigerants. These requirements have increased our training expenses and expenditures for containment and recycling equipment. The Clean Air Act is intended ultimately to eliminate the use of CFCs in the United States and to require alternative refrigerants to be used in replacement HVAC systems. We do not believe these regulations involving CFCs will materially affect our business on the whole because, although they require us to incur modest ongoing training costs, our competitors also incur such costs, and the regulations may encourage our customers to update their HVAC systems.

Executive Officers

We have four executive officers.

William F. Murdy, age 64, has served as our Chairman of the Board and Chief Executive Officer since June 2000. Prior to this he was Interim President and Chief Executive Officer of Club Quarters, a privately-owned chain of membership hotels.

From 1987 to 1995, she held various positions with Arthur Andersen LLP. Ms. Shaeff is a Certified Public Accountant.

ITEM 1A. Company Risk Factors

Because we bear the risk of cost overruns in most of our contracts, we may experience reduced profits or, in some cases, losses under these contracts if costs increase above our estimates.

Our contract prices are established largely upon estimates and assumptions, which include assumptions about future economic conditions, prices and availability of labor, equipment and materials and other exigencies. If these estimates prove to be inaccurate or circumstances change such as unanticipated technical problems, difficulties in obtaining permits or approvals, changes in local laws or labor conditions, weather delays, fluctuations in cost of raw materials, or our suppliers’ or subcontractors’ inability to perform, cost overruns may occur, and we could experience reduced profits or, in some cases, a loss for the project. Additionally, in certain circumstances, we guarantee project completion or the achievement of certain acceptance and performance testing levels by a scheduled date. Failure to meet schedule or performance requirements could result in additional costs to us. While we may seek to recover these amounts as claims from the supplier, vendor, subcontractor or other third party responsible for the delay or for providing non-conforming products or services, we cannot be certain that we will recover all or any part of these costs in all circumstances. Performance problems for existing and future projects could cause our actual results of operations to differ materially from those anticipated by us and could damage our reputation within our industry and our customer base.

Our backlog is subject to unexpected adjustments and cancellations, which means that amounts included in our backlog may not result in actual revenue or translate into profits.

We cannot guarantee that the revenues projected in our backlog will be realized or, if realized, will result in profits. Projects may remain in our backlog for an extended period of time or project cancellations or scope adjustments may occur with respect to contracts reflected in our backlog. Finally, poor project or contract performance could also impact our profits. The revenue projected from our backlog may not be realized or, if realized, may not result in profits.

We may be adversely impacted by the seasonal and cyclical nature of the markets we serve, and an economic downturn in the industries we serve may result in certain of our customers being unable to pay us on a timely basis, or at all, and lead to a decrease in demand for our services.

The demand for our services is dependent upon the existence of construction projects and service requirements within the industries in which we operate. Any downturn in the commercial, industrial and institutional HVAC markets or any other of our markets could adversely impact our performance. The industries we operate in have been and will continue to be vulnerable to general downturns and are cyclical in nature. As a result, our results may vary depending upon the demand for projects within the industries we serve.

We continue to expand our business in areas where bonding is required, but bonding capacity is limited.

In the past we have expanded and we intend to continue to expand the number of total contract dollars that require an underlying bond. Because of an overall industry-wide lack of bonding capacity, we may find it difficult to find sureties who will provide the contractually required bonding. We may not be able to maintain a sufficient level of bonding capacity in the future, which could preclude us from being able to bid for certain contracts and successfully contract with certain customers. Additionally, even if we are able to successfully increase bonding capacity to sufficiently bond future work, we may be required to post collateral to secure bonds which would decrease the liquidity that we would have available for other purposes.

Our use of the percentage-of-completion method of accounting could result in a reduction or reversal of previously recorded revenues or profits.

A material portion of our revenues are recognized using the percentage-of-completion method of accounting. The percentage-of-completion accounting practices that we use result in our recognizing contract revenues and earnings ratably over the contract term in the proportion that our actual costs bear to our estimated contract costs. The earnings or losses recognized on individual contracts are based on estimates of contract revenues, costs and profitability. We review our estimates of contract revenues, costs and profitability on an ongoing basis. Prior to contract completion, we may adjust our estimates on one or more occasions as a result of change orders to the original contract, collection disputes with the customer on amounts invoiced or claims against the customer for increased costs incurred by us due to customer-induced delays and other factors. Contract losses are recognized in the fiscal period when the loss is determined. Contract profit estimates are also adjusted in the fiscal period in which it is determined that an adjustment is required. As a result of the requirements of the percentage-of-completion method of accounting, the possibility exists, for example, that we could have estimated and reported a profit on a contract over several periods and later determined, usually near contract completion, that all or a portion of such previously estimated and reported profits were overstated. If this occurs, the full aggregate amount of the overstatement will be reported for the period in which such determination is made, thereby eliminating all or a portion of any profits from other contracts that would have otherwise been reported in such period or even resulting in a loss being reported for such period. On a historical basis, we believe that we have made reasonably reliable estimates of the progress towards completion on our long-term contracts. However, given the uncertainties associated with these types of contracts, it is possible for actual costs to vary from estimates previously made, which may result in reductions or reversals of previously recorded revenues and profits.

Intense competition in our industry could reduce our market share and our profits.

The markets we serve are highly competitive. Our industry is characterized by many small companies whose activities are geographically concentrated. We compete on the basis of our technical expertise and experience, financial and operational resources, nationwide presence, industry reputation and our

dependability. While we believe our customers consider a number of these factors in awarding available contracts, a large portion of our work is awarded through a bid process. Consequently, price is often the principal factor in determining which contractor is selected, especially on smaller, less complex projects. Smaller competitors are sometimes able to win bids for these projects based on price alone due to their lower cost and financial return requirements. Intense competition is expected to continue in our industry, presenting us with significant challenges in our ability to maintain strong growth rates and acceptable profit margins. If we are unable to meet these competitive challenges, we could lose market share to our competitors and experience an overall reduction in our profits.

If we are unable to attract and retain qualified managers and employees, we will be unable to operate efficiently, which could reduce our profitability.

Our business is labor intensive, and many of our operations experience a high rate of employment turnover. At times of low unemployment rates in the United States, it will be more difficult for us to find qualified personnel at low cost in some geographic areas where we operate. Additionally, our business is managed by a small number of key executive and operational officers. We may be unable to hire and retain the sufficient skilled labor force necessary to operate efficiently and to support our growth strategy. Our labor expenses may increase as a result of a shortage in the supply of skilled personnel. Labor shortages, increased labor costs or the loss of key personnel could result in reduced profitability, which would negatively impact our business.

Past and future environmental, safety and health regulations could impose significant additional costs on us that reduce our profits.

HVAC systems are subject to various environmental statutes and regulations, including the Clean Air Act and those regulating the production, servicing and disposal of certain ozone depleting refrigerants used in HVAC systems. There can be no assurance that the regulatory environment in which we operate will not change significantly in the future. Various local, state and federal laws and regulations impose licensing standards on technicians who install and service HVAC systems. Our failure to comply with these laws and regulations could subject us to substantial fines and potentially the loss of our licenses. It is impossible to predict the full nature and effect of judicial, legislative or regulatory developments relating to health and safety regulations and environmental protection regulations applicable to our operations.

We are effectively self-insured against many potential liabilities, and our risk management policies and procedures may leave us exposed to unidentified or unanticipated risks.

Although we maintain insurance policies with respect to our related exposures, these policies are subject to high deductibles; as such, we are effectively self-insured for substantially most of our claims. We actuarially determine any liabilities for unpaid claims and associated expenses for the three major lines of coverage (Worker’s Compensation, General Liability and Auto Liability). The determination of such claims and expenses and the appropriateness of the estimated liability are reviewed and updated quarterly. However, insurance liabilities are difficult to assess and estimate due to the many relevant factors, the effects of which are often unknown, including the severity of an injury, the determination of our liability in proportion to other parties, the number of incidents that have occurred but are not reported and the effectiveness of our safety program. Our accruals are based upon known facts, historical trends (both internal trends and industry averages) and our reasonable estimate of our future expenses and we believe such accruals to be adequate. However, our risk management strategies and techniques may not be fully effective in mitigating our risk exposure in all market environments or against all types of risk. If any of the variety of instruments, processes and strategies we utilize to mange our exposure to various types of risk are not effective, we may incur losses that are not covered by our insurance policies or that exceed our accruals or that exceed our coverage limits.

If we experience delays and/or defaults in customer payments, we could be unable to recover all expenditures.

Because of the nature of our contracts, at times we commit resources to projects prior to receiving payments from the customer in amounts sufficient to cover expenditures on projects as they are incurred. Delays in customer payments may require us to make a working capital investment. If a customer defaults in making its payments on a project in which we have devoted resources, it could have a material negative effect on our results of operations.

Actual and potential claims, lawsuits and proceedings could ultimately reduce our profitability and liquidity and weaken our financial condition.

We are likely to continue to be named as a defendant in legal proceedings claiming damages from us in connection with the operation of our business. Most of the actions against us arise out of the normal course of our performing services on project sites. We also are and are likely to continue to be a plaintiff in legal proceedings against customers, in which we seek to recover payment of contractual amounts due to us as well as claims for increased costs incurred by us. When appropriate we establish provisions against certain legal exposures, and we adjust such provisions from time to time according to ongoing developments related to each exposure. If in the future our assumptions and estimates related to such exposures prove to be inadequate or wrong, we could experience a reduction in our profitability and liquidity and a weakening of our financial condition. In addition, claims, lawsuits and proceedings may harm our reputation or divert management resources away from operating our business.

Our recent and future acquisitions may not be successful.

We expect to continue to pursue extremely selective acquisitions of businesses. We cannot assure you that we will be able to locate acquisitions or that we will be able to consummate any such transactions on terms and conditions acceptable to us, or that such transactions will be successful. Acquisitions may expose us to additional business risks that are different than those we have traditionally experienced. We also may encounter difficulties integrating acquisitions and successfully managing the growth we expect to experience from these acquisitions.

Our common stock, which is listed on the New York Stock Exchange, has from time-to-time experienced significant price and volume fluctuations. These fluctuations are likely to continue in the future, and our stockholders may not be able to resell their shares of common stock at or above the purchase price paid.

The market price of our common stock may change significantly in response to various factors and events beyond our control. A variety of events may cause the market price of our common stock to fluctuate significantly, including the following: (i) the risk factors described in this Report on Form 10-K; (ii) a shortfall in operating revenue or net income from that expected by securities analysts and investors; (iii) changes in securities analysts’ estimates of our financial performance or the financial performance of our competitors or companies in our industry generally; (iv) general conditions in our customers’ industries; (v) general conditions in the securities markets; (vi) our announcements of significant contracts, milestones, acquisitions; (vii) our relationship with other companies; (viii) our investors’ view of the sectors and markets in which we operate; and (ix) additions or departures of key personnel. Some companies that have volatile market prices for their securities have been subject to security class action suits filed against them. If a suit were to be filed against us, regardless of the outcome, it could result in substantial costs and a diversion of our management’s attention and resources. This could have a material adverse effect on our business, results of operations and financial condition.

If we do not effectively manage our growth, our existing infrastructure may become strained, and we may be unable to increase revenue growth.

The growth that we have experienced, and in the future may experience, may provide challenges to our organization, requiring us to expand our personnel and our operations. Future growth may strain our infrastructure, operations and other managerial and operating resources. If our business resources become strained, we may be unable to increase revenue growth.

Our earnings for fiscal year 2005 were negatively impacted by impairment charges. Earnings for future periods may be further affected by additional impairment charges.

Because we previously grew in large part through acquisitions, goodwill and other acquired intangible assets represent a substantial portion of our assets. We perform an annual goodwill impairment review in the fourth quarter of every fiscal year. In addition, we perform a goodwill impairment review whenever events or changes in circumstances indicate the carrying value may not be recoverable. As a result of our goodwill impairment review in the fourth quarter of 2005, we recorded a goodwill impairment charge of $33.9 million. Additionally, at some future date, we may determine that an additional significant impairment has occurred in the value of our unamortized intangible assets or fixed assets, which could require us to write off an additional portion of our assets and could adversely affect our financial condition or our reported results of operations.

Failure or circumvention of our disclosure controls and procedures or internal controls over financial reporting could seriously harm our business.

We plan to continue to maintain and strengthen internal controls and procedures to enhance the effectiveness of our disclosure controls and internal controls over financial reporting. Any system of controls, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, and not absolute, assurances that the objectives of the system are met. Any failure of our disclosure controls and procedures or internal controls over financial reporting could harm our financial condition and results of operations.

Our charter contains certain anti-takeover provisions that may inhibit or delay a change in control.

Our certificate of incorporation authorizes our Board of Directors to issue, without stockholder approval, one or more series of preferred stock having such preferences, powers and relative, participating, optional and other rights (including preferences over the common stock respecting dividends and distributions and voting rights) as the Board of Directors may determine. The issuance of this “blank-check” preferred stock could render more difficult or discourage an attempt to obtain control by means of a tender offer, merger, proxy contest or otherwise. Additionally, certain provisions of the Delaware General Corporation Law may also discourage takeover attempts that have not been approved by the Board of Directors.

Failure to successfully comply with Section 404 of the Sarbanes-Oxley Act of 2002 on a timely basis could seriously harm our business.

Section 404 of the Sarbanes-Oxley Act of 2002 requires our management to report on our internal controls over financial reporting and also requires our independent registered public accountants to attest to this report. Although we have historically been able to successfully comply with Section 404, in the future, we may not be successful in complying with Section 404 on a timely basis. The failure to comply with Section 404 could harm our financial condition and results of operations.

ITEM 2. Properties

We lease the real property and buildings from which we operate. Our facilities are located in over 24 states and Puerto Rico and consist of offices, shops, maintenance and warehouse facilities. Generally, leases range from three to ten years and are on terms we believe to be commercially reasonable. A majority of these premises are leased from individuals or entities with whom we have no other business relationship. In certain instances these leases are with employees who are also the former owners of companies we purchased from 1997 through 1999. These leases were entered into in connection with the acquisition of the companies these individuals owned. To the extent we renew these leases or otherwise change them, we enter into such agreements on terms that reflect a fair market valuation for the properties. Leased premises range in size from approximately 1,000 square feet to 130,000 square feet. To maximize available capital, we generally intend to continue to lease our properties, but may consider owning properties where we believe ownership would be more economical. We believe that our facilities are sufficient for our current needs.

We lease our executive and administrative offices in Houston, Texas.

ITEM 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with the Consolidated Financial Statements and related notes included elsewhere in this annual report on Form 10-K. Also see “Forward-Looking Statements” discussion.

Introduction and Overview

We are a national provider of comprehensive heating, ventilation and air conditioning (“HVAC”) installation, maintenance, repair and replacement services within the mechanical services industry. The services we provide address a very broad need, as air is circulated through almost all commercial, industrial and institutional buildings virtually year-round. We operate primarily in the commercial, industrial and institutional HVAC markets and perform most of our services within office buildings, retail centers, apartment complexes, manufacturing plants, and healthcare, education and government facilities. In addition to standard HVAC services, we provide specialized applications such as building automation control systems, fire protection, process cooling, electronic monitoring and process piping. Certain locations also perform related activities such as electrical service and plumbing.

Nature and Economics of Our Business

Approximately 85% of our revenues are earned on a project basis for installation of HVAC systems in newly constructed facilities or for replacement of HVAC systems in existing facilities. Customers hire us to ensure such systems deliver specified or generally expected heating, cooling, conditioning and circulation of air in a facility. This entails installing core system equipment such as packaged heating and air conditioning units, or in the case of larger facilities, separate core components such as chillers, boilers, air handlers, and cooling towers. We also typically install connecting and distribution elements such as piping and ducting. Our responsibilities usually require conforming the systems to pre-established engineering drawings and equipment and performance specifications, which we frequently participate in establishing. Our project management responsibilities include staging equipment and materials to project sites, deploying labor to perform the work, and coordinating with other service providers on the project, including any subcontractors we might use to deliver our portion of the work.

When competing for project business, we usually estimate the costs we will incur on a project, then propose a bid to the customer that includes a contract price and other performance and payment terms. Our bid price and terms are intended to cover our estimated costs on the project and provide a profit margin to us commensurate with the value of the installed system to the customer, the risk that project costs or duration will vary from estimate, the schedule on which we will be paid, the opportunities for other work that we might forego by committing capacity to this project, and other costs that we incur more broadly to support our operations but which are not specific to the project. Typically customers will seek bids from competitors for a given project. While the criteria on which customers select the winning bid vary widely and include factors such as quality, technical expertise, on-time performance, post-project support and service, and company history and financial strength, we believe that price is the most influential factor for most customers in choosing an HVAC installation and service provider.

After a customer accepts our bid, we generally enter into a contract with the customer that specifies what we will deliver on the project, what our related responsibilities are, and how much and when we will be paid. Our overall price for the project is typically set at a fixed amount in the contract, although changes in project specifications or work conditions that result in unexpected additional work are usually subject to additional payment from the customer via what are commonly known as change orders. Project contracts typically provide for periodic billings to the customer as we meet progress milestones or incur cost on the project. Project contracts in our industry also frequently allow for a small portion of progress billings or

contract price to be withheld by the customer until after we have completed the work, typically for six months. Amounts withheld under this practice are known as retention or retainage.

Labor and overhead costs account for the majority of our cost of service. Accordingly, labor management and utilization have the most impact on our project performance. Given the fixed price nature of much of our project work, if our initial estimate of project costs is wrong or we incur cost overruns that cannot be recovered in change orders, we can experience reduced profits or even significant losses on fixed price project work. We also perform some project work on a cost-plus or a time and materials basis, under which we are paid our costs incurred plus an agreed-upon profit margin. These margins are typically less than fixed-price contract margins because there is less risk of unrecoverable cost overruns in cost-plus or time and materials work.

As of December 31, 2005, we had 4,642 projects in process. Our average project takes three to six months to complete, with an average contract price of approximately $300,000. Our projects generally require working capital funding of equipment and labor costs. Customer payments on periodic billings generally do not recover these costs until late in the job. Our average project duration together with typical retention terms as discussed above generally allow us to complete the realization of revenue and earnings in cash within one year. Because of the integral nature of HVAC and related controls systems to most buildings, we have the legal right in almost all cases to attach liens to buildings or related funding sources when we have not been fully paid for installing systems, except with respect to some government buildings. The service work that we do, which is discussed further below, usually does not give rise to lien rights.

We also perform larger HVAC projects. As of December 31, 2005, we had one project in process with a contract price of between $15 and $25 million, eight projects between $10 million and $15 million, 29 projects between $5 million and $10 million, and 177 projects between $1 million and $5 million. Taken together, projects with contract prices of $1 million or more totaled $706.5 million of aggregate contract value as of December 31, 2005, or approximately 51%, out of a total contract value for all projects in progress of $1,391.3 million. Generally, projects closer in size to $1 million will be completed in one year or less. It is unusual for us to work on a project that exceeds two years in length.

In addition to project work, approximately 15% of our revenues represent maintenance and repair service on already-installed HVAC and controls systems. This kind of work usually takes from a few hours to a few days to perform. Prices to the customer are usually based on the equipment and materials used in the service as well as technician labor time. We usually bill the customer for service work when it is complete, typically with payment terms of up to thirty days. We also provide maintenance and repair service under ongoing contracts. Under these contracts, we are paid regular monthly or quarterly amounts and provide specified service based on customer requirements. These agreements typically cover periods ranging from one to three years and are cancelable on 30 to 60 days notice.

A relatively small but growing portion of our revenues comes from national and regional account customers. These customers typically have multiple sites, and contract with us to perform maintenance and repair service. These contracts may also provide for us to perform new or replacement systems installation. We operate a national call center to dispatch technicians to sites requiring service. We perform the majority of this work with our own employees, with the balance being subcontracted to third parties that meet our performance qualifications. We will also typically use proprietary information systems to maintain information on the customer’s sites and equipment, including performance and service records, and related cost data. These systems track the status of ongoing service and installation work, and may also monitor system performance data. Under these contractual relationships, we usually provide consolidated billing and credit payment terms to the customer.

Profile and Management of Our Operations

Our company was originally formed in 1997 through an initial public offering, or IPO, and simultaneous acquisition of 12 companies engaged in our business. From the time we completed our IPO through December 1999, we acquired 107 HVAC and complementary businesses, of which 26 were “tuck-in” operations that were integrated upon acquisition with existing operations. From 2000 through 2004 we did not acquire any additional companies but rather shifted our strategy from an emphasis on acquisition-based growth to a focus on improving the performance of our existing operations. During that time, we sold or ceased operations at 35 companies and consolidated another 13 companies into other operations. In January 2005 we acquired a business in New England. During 2005, we sold or ceased operations at five of our operating companies and consolidated one company into other operations. Today we have 40 operating units.

We manage our operations based on a variety of factors. Financial measures we emphasize include profitability, and use of capital as indicated by cash flow and by other measures of working capital principally involving project cost, billings and receivables. We also monitor selling, general, administrative and indirect project support expense, backlog, workforce size and mix, growth in revenues and profits, variation of actual project cost from original estimate, and overall financial performance in comparison to budget and updated forecasts. Operational factors we emphasize include project selection, estimating, pricing, management and execution practices, labor utilization, safety, training, and the make-up of both existing backlog as well as new business being pursued, in terms of project size, technical application and facility type, end-use customers and industries, and location of the work.

Most of our operations compete on a local or regional basis. Attracting and retaining effective operating unit managers is an important factor in our business, particularly in view of the relative uniqueness of each market and operation, the importance of relationships with customers and other market participants such as architects and consulting engineers, and the high degree of competition and low barriers to entry in most of our markets. Accordingly, we devote considerable attention to operating unit management quality, stability, and contingency planning, including related considerations of compensation, and non-competition protection where applicable.

Economic and Industry Factors

As an HVAC and building controls services provider, we operate in the broader nonresidential construction services industry and are affected by trends in this sector. While we do not have operations in all major cities of the US, we believe our national presence is sufficiently large that we experience trends in demand for and pricing of our services that are consistent with trends in the national nonresidential construction sector. As a result, we monitor the views of major construction sector forecasters along with macroeconomic factors they believe drive the sector, including trends in gross domestic product, interest rates, business investment, employment, demographics, and the general fiscal condition of federal, state and local governments. Although nonresidential construction activity has demonstrated periods of both significant growth and decline, it has grown at a compound annual rate of approximately 4.2% over the last twenty-five years.

Spending decisions for building construction, renovation and system replacement are generally made on a project basis, usually with some degree of discretion as to when and if projects proceed. With larger amounts of capital, time, and discretion involved, spending decisions are affected to a significant degree by uncertainty, particularly concerns about macroeconomic and geopolitical trends. We have experienced periods of time, such as after the terrorist incidents on September 11, 2001 in the US, and prior to and during the war in Iraq that occurred in early 2003, when uncertainty caused a significant slowdown in decisions to proceed with installation and replacement project work. The Company believes that the current economic environment is favorable relative to the activity levels of recent years.

Operating Environment and Management Emphasis

Nonresidential building construction and renovation activity, as reported by the federal government, declined over the three year period of 2001 to 2003 and has expanded moderately during 2004 and 2005. During the decline and through 2003, we responded to market challenges by pursuing work in sectors less affected by this downturn, such as government, educational, and health care facilities, and by establishing marketing initiatives that take advantage of our size and range of expertise. We also responded to declining gross profits over those years by reducing our selling, general, and administrative expenses, and our indirect project and service overhead costs. We believe our efforts in these areas partially offset the decline in our profitability over that period. We have experienced notable improvements in both industry activity as well as our own results throughout 2004 and 2005, as discussed further under “Results of Operations” below.

As a result of our sale of certain assets and our continued strong emphasis on cash flow, our debt outstanding is now zero, and we have substantial uncommitted cash balances, as discussed further in “Liquidity and Capital Resources” below. At the end of June 2005, we put a new credit facility in place with considerably less restrictive terms than those of our previous facilities. In addition, we have added a second surety to further support our bonding needs, and we believe our relationships with the surety markets are positive in light of our strong current results and financial position. We have generated positive free cash flow in each of the last five calendar years and will continue our emphasis in this area. We believe that the relative size and strength of our balance sheet and surety support as compared to most companies in our industry represent competitive advantages for us.

As discussed at greater length in “Results of Operations” below, we have seen increased activity levels in our industry in 2004, and throughout 2005. We expect price competition to continue to be strong, as local and regional competitors respond cautiously to changing conditions. We will continue our efforts to find the more active sectors in our markets, and to increase our regional and national account business. However, our primary emphasis for 2006 will be on internal execution and margin improvement, rather than on revenue growth. In addition to the work we have done on our underperforming units, we have increased our focus on project qualification, estimating, pricing and management, and on service performance. This focus includes significant increases in unit level training.

There was substantial cost inflation in 2004 in certain commodities that are used in construction activity, including steel, iron, copper, lumber, and poly-vinyl chloride (“PVC”) pipe. We estimate that direct purchase of these commodities, principally steel, iron and copper, comprises between 10% and 15% of our average project cost. As noted below in “Results of Operations,” for some of the project work we have performed in 2004, the actual cost of certain commodities necessary for these projects was significantly greater than the commodity cost estimates we used when we committed to prices for these projects, which typically was done in 2003 before commodity cost inflation became apparent. We experienced most of the negative effect of this unrecovered commodity cost inflation in the second quarter of 2004. We began taking steps early in 2004 to reduce future commodity cost exposure. Among these steps were early buying of commodities for particular projects, or for general inventory, as well as including escalation and escape provisions in project bids and contracts wherever possible. Following our second quarter impact, we experienced virtually no unrecovered cost inflation in the second half of 2004. However, commodity markets remain unsettled, and while we are taking steps as noted above to minimize unrecoverable commodity cost inflation, these steps cannot guarantee that we will avoid all such exposure. More broadly, it is also possible that further increases in or uncertainty about commodity costs will decrease demand for nonresidential construction activity, which could in turn reduce our future revenues. In 2005, we have not seen an identifiable negative effect of commodity costs on activity in our industry.

Based on indications of stabilizing industry conditions and on our emphasis on internal execution and margin improvement, we expect that our 2006 results will be better than our 2005 results, although there

can be no assurance that we will achieve this outcome. Over the longer term, if industry conditions are stable to improving, we believe we will experience more periods of increased revenues. In addition, given the size and fragmentation of our industry, we believe it makes sense for us to consider acquisition possibilities. However, we plan to do so on a very selective, opportunistic basis, and expect our growth in 2006 will largely be generated internally.

Critical Accounting Policies

In response to the Commission’s Release No. 33-8040, “Cautionary Advice Regarding Disclosure About Critical Accounting Policies,” we identified our critical accounting policies based upon the significance of the accounting policy to our overall financial statement presentation, as well as the complexity of the accounting policy and our use of estimates and subjective assessments. We have concluded that our most critical accounting policy is our revenue recognition policy. As discussed elsewhere in this annual report on Form 10-K, our business has two service functions: (i) installation, which we account for under the percentage of completion method, and (ii) maintenance, repair and replacement, which we account for as the services are performed, or in the case of replacement, under the percentage of completion method. In addition, we identified other critical accounting policies related to our allowance for doubtful accounts receivable, the recording of our self-insurance liabilities, valuation of deferred tax assets and the assessment of goodwill impairment. These accounting policies, as well as others, are described in Note 2 to the Consolidated Financial Statements included elsewhere in this annual report on Form 10-K.

Percentage of Completion Method of Accounting

Approximately 85% of our revenues were earned on a project basis and recognized through the percentage of completion method of accounting. Under this method as provided by American Institute of Certified Public Accountants Statement of Position 81-1, “Accounting for Performance of Construction-Type and Certain Production-Type Contracts,” contract revenue recognizable at any time during the life of a contract is determined by multiplying expected total contract revenue by the percentage of contract costs incurred at any time to total estimated contract costs. More specifically, as part of the negotiation and bidding process in which we engage in connection with obtaining installation contracts, we estimate our contract costs, which include all direct materials (exclusive of rebates), labor and subcontract costs and indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs and depreciation costs. These contract costs are included in our results of operations under the caption “Cost of services.” Then, as we perform under those contracts, we measure such costs incurred, compare them to total estimated costs to complete the contract, and recognize a corresponding proportion of contract revenue. Labor costs are considered to be incurred as the work is performed. Subcontractor labor is recognized as the work is performed, but is generally subjected to approval as to milestones or other evidence of completion. Non-labor project cost consists of purchased equipment, prefabricated materials and other materials. Purchased equipment on our projects are substantially all produced to job specifications and are a value added element to our work. The costs are considered to be incurred when title is transferred to us, which typically is upon delivery to the work site. Prefabricated materials, such as ductwork and piping, are generally performed at our shops and recognized as contract costs when fabricated for the unique specifications of the job. Other materials cost are not significant and are generally recorded when delivered to the work site. This measurement and comparison process requires updates to the estimate of total costs to complete the contract, and these updates may include subjective assessments.

Our contracts typically provide for a schedule of billings or invoices to the customer based on reaching agreed-upon milestones or as we incur costs. The schedules for such billings usually do not precisely match the schedule on which we incur costs. As a result, contract revenues recognized in the statement of

operations can and usually do differ from amounts that can be billed or invoiced to the customer at any point during the contract. Amounts by which cumulative contract revenues recognized on a contract as of a given date exceed cumulative billings to the customer under the contract are reflected as a current asset in our balance sheet under the caption “Costs and estimated earnings in excess of billings.” Amounts by which cumulative billings to the customer under a contract as of a given date exceed cumulative contract revenues recognized on the contract are reflected as a current liability in our balance sheet under the caption “Billings in excess of costs and estimated earnings.”

The percentage of completion method of accounting is also affected by changes in job performance, job conditions, and final contract settlements. These factors may result in revisions to estimated costs and, therefore, revenues. Such revisions are frequently based on further estimates and subjective assessments. We recognize these revisions in the period in which they are determined. If such revisions lead us to conclude that we will recognize a loss on a contract, the full amount of the estimated ultimate loss is recognized in the period we reach that conclusion, regardless of the percentage of completion of the contract.

Revisions to project costs and conditions can give rise to change orders under which the customer agrees to pay additional contract price. Revisions can also result in claims we might make against the customer to recover project variances that have not been satisfactorily addressed through change orders with the customer. Except in certain circumstances, we do not recognize revenues or margin based on change orders or claims until they have been agreed upon with the customer. The amount of revenue associated with unapproved change orders and claims is currently immaterial. Variations from estimated project costs could have a significant impact on our operating results, depending on project size, and the recoverability of the variation via additional customer payments.

Accounting for Allowance for Doubtful Accounts

We are required to estimate the collectibility of accounts receivable and provide an allowance for doubtful accounts for receivable amounts we believe we will not ultimately collect. This requires us to make certain judgments and estimates involving, among others, the creditworthiness of the customer, our prior collection history with the customer, ongoing relationships with the customer, the aging of past due balances, our lien rights, if any, in the property where we performed the work, and the availability, if any, of payment bonds applicable to our contract. These estimates are re-evaluated and adjusted as additional information is received.

Accounting for Self-Insurance Liabilities

We are substantially self-insured for worker’s compensation, employer’s liability, auto liability, general liability and employee group health claims in view of the relatively high per-incident deductibles we absorb under our insurance arrangements for these risks. Losses up to deductible amounts are estimated and accrued based upon known facts, historical trends and industry averages. Loss estimates associated with the larger and longer-developing risks—worker’s compensation, auto liability and general liability—are reviewed by a third party actuary quarterly. We believe these accruals are adequate. However, insurance liabilities are difficult to estimate due to unknown factors, including the severity of an injury, the determination of our liability in proportion to other parties, timely reporting of occurrences, ongoing treatment or loss mitigation, general trends in litigation recovery outcomes and the effectiveness of safety and risk management programs. Therefore, if actual experience differs from the assumptions and estimates used for recording the liabilities, adjustments may be required and would be recorded in the period that such experience becomes known.

Accounting for Deferred Tax Assets

We regularly evaluate valuation allowances established for deferred tax assets for which future realization is uncertain. We perform this evaluation quarterly. Estimations of required valuation allowances include estimates of future taxable income. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which the activity underlying these assets becomes deductible. We consider projected future taxable income and tax planning strategies in making this assessment. If actual future taxable income differs from our estimates, we may not realize deferred tax assets to the extent we have estimated.

Accounting for Goodwill and Other Intangible Assets

In most businesses we have acquired, the value we paid to buy the business was greater than the value of specifically identifiable net assets in the business. Under generally accepted accounting principles, this excess is termed goodwill and is recognized as an asset at the time the business is acquired. It is generally expected that future net earnings from an acquired business will exceed the goodwill asset recognized at the time the business is bought.

Statement of Financial Accounting Standards (“SFAS”) No. 142, “Goodwill and Other Intangible Assets” requires us to assess our goodwill asset amounts for impairment each year, and more frequently if circumstances suggest an impairment may have occurred. Impairment must be reflected when the value of a given business unit in excess of its tangible net assets falls below the goodwill asset balance carried for that unit on our books. If other business units have had increases in the value of their respective goodwill balances, such increases may not be recorded under SFAS No. 142. Accordingly, such increases may not be netted against impairments at other business units. The requirements for assessing whether goodwill assets have been impaired involve market-based information. This information, and its use in assessing goodwill, entails some degree of subjective assessment.

We currently perform our annual impairment testing as of October 1 and any impairment charges resulting from this process are reported in the fourth quarter. We segregated our operations into reporting units based on the degree of operating and financial independence of each unit and our related management of them. These reporting units are tested for impairment by comparing the unit’s fair value to its carrying value. The fair value of each reporting unit was estimated using a discounted cash flow model combined with market valuation approaches. Significant estimates and assumptions are used in assessing the fair value of reporting units. These estimates and assumptions involved future cash flows, growth rates, discount rates, weighted average cost of capital and estimates of market valuations for each of the reporting units.

We recorded goodwill impairment charges of $2.7 million, $0.6 million and $33.9 million in operating results during the fourth quarters of 2003, 2004 and 2005, respectively. We recorded an additional impairment charge of $2.7 million in 2004 related to operations that were subsequently discontinued in 2005. This impairment charge is reflected in operating income (loss) associated with discontinued operations. The impairment charges during 2003 primarily resulted from changes in operating plans that were identified in the fourth quarter of 2003 for certain of our reporting units as part of our annual budgeting and business planning process. The impairment charge during 2004 and 2005 resulted from our estimation that the operating environment, conditions and performance of certain of our entities could no longer support the goodwill balances associated with them.

Table 2—Supplemental Non-GAAP Disclosure—Operating Results of Ongoing Operations Excluding Certain Items

The following table presents information excluding restructuring charges, writeoff of debt costs and discounts, net and goodwill impairment charges. We have included this table because we believe it offers an additional view of the core results of our continuing operations in a way we find useful in managing these operations, and in a way which also responds to frequent questions we receive about the Company from third parties. However, this presentation of operating results is not in accordance with generally accepted accounting principles, and should not be considered an alternative to income as determined under generally accepted accounting principles and presented above in Table 1—Historical Results. In particular, while this table excludes restructuring charges, we recorded them in 2003. In addition, impairment charges under the goodwill accounting rules are generally expected to occur periodically as goodwill recognized in connection with the acquisition of businesses responds over time to changes in those businesses’ markets and operations. We recorded goodwill impairment charges in each of the years 2003-2005.

2005 Compared to 2004

Revenues—Revenues increased $120.9 million, or 15.5%, to $899.5 million in 2005 compared to 2004. Approximately 11.9% of the increase in revenues related to internal growth and the remaining 3.6% resulted from the acquisition of Granite State Plumbing & Heating (“Granite”) in January 2005. The internal revenue growth stemmed primarily from generally improving nonresidential facilities markets throughout the United States especially in the institutional markets such as schools and hospitals (approximately $32.8 million), hotels (approximately $12.5 million), and in the multi-family sector (approximately $23.2 million). We have seen increased activity, primarily in our Alabama, Arizona, Florida and Wisconsin operations, resulting from the start-up of several large projects. These gains were offset to a lesser degree by lower revenues relating to our operations in Southern California that were impacted by continued project delays resulting from extended inclement weather in the first quarter of 2005.

Backlog reflects revenues still to be recognized under contracted or committed installation and replacement project work. Project work generally lasts less than one year. Service agreement revenues and service work and short duration projects which are generally billed as performed do not flow through backlog. Accordingly, backlog represents only a portion of our revenues for any given future period, and it represents revenues that are likely to be reflected in our operating results over the next six to twelve months. As a result, we believe the predictive value of backlog information is limited to indications of general revenue direction over the near term, and should not be interpreted as indicative of ongoing revenue performance over several quarters.

Backlog associated with continuing operations as of December 31, 2005 was $681.7 million (including $13.0 million from the acquisition of Granite), a 7.3% increase from September 30, 2005 backlog of $635.3 million, and a 32.9% increase from December 31, 2004 backlog of $512.8 million. These gains result primarily from significant new multi-family projects in Alabama, as well as office building projects in the Washington, D.C. area.

Following the three-year period of industry activity declines from 2001-2003 noted previously, we saw modest year-over-year revenue increases at our ongoing operations beginning in mid-2003 and continuing throughout 2004 and 2005. We continue to see signs that activity levels in our industry may continue to increase throughout 2006. These observations are based on nonresidential construction spending trends, shipment data from HVAC equipment manufacturers, forecasts from construction industry analysts, and anecdotal indications of renewed project consideration.

Along with the indications noted above that suggest industry activity is improving, there remain the following cautionary factors in the industry environment, each of which is discussed at greater length in the Introduction above. Since HVAC and related installation and replacement decisions are capital decisions usually involving some amount of discretion, they tend to be affected to a greater degree by macroeconomic or geopolitical uncertainty. Negative developments or events in these arenas, should they occur, will likely cause end users to defer HVAC and related spending decisions, thereby reducing our revenues.

We continue to experience a noticeable amount of price competition in our markets, which restrains our ability to increase revenues.

While we believe we will see increased industry activity levels throughout 2006, in view of all of the foregoing factors, we may continue to experience only modest revenue growth or revenue declines in upcoming periods. In addition, if general economic activity in the US slows significantly from current levels, we may realize decreases in revenue and lower operating margins.

Gross Profit—Gross profit increased $25.2 million, or 20.7%, to $147.2 million in 2005 compared to 2004. As a percentage of revenues, historical gross profit for 2005 was 16.4%, up from 15.7% in 2004. The increase in gross profit percentage resulted primarily from increased profitability in our Arizona operations (approximately $3.4 million), higher margin storm-related project repair work performed by our operation in Central Florida (approximately $3.7 million) and improved margins at an operation in Wisconsin which was negatively impacted by increases in the prices for certain commodity materials in 2004 (approximately $3.7 million). These gains were partially offset by job underperformance at one of our larger operations (approximately $5.0 million).

As noted in the Introduction above, we are currently placing a greater emphasis on internal execution and margin improvement than on revenue growth. This includes a strong focus on those of our units that have underperformed, along with increased training efforts on project qualification, estimating, pricing and management, and on service performance. While we believe these efforts will help us increase gross profits, we cannot assure that this will occur. Further, if we are successful in these efforts, we cannot assure that they will offset adverse industry trends, if such trends occur.

Selling, General and Administrative Expenses (“SG&A”)—SG&A increased $13.8 million, or 13.7% for 2005 as compared to 2004. As a percentage of revenues, SG&A declined from 13.0% in 2004 to 12.7% in 2005. This decrease is consistent with our effort to control our SG&A expenses as we experience internal revenue growth, partially offset by an increase resulting from higher medical costs (approximately $3.1 million) in 2005 due to medical inflation in 2005 and favorable claims experience in the prior year.

Goodwill Impairment—We recorded goodwill impairment charges of $0.6 million and $33.9 million during the fourth quarters of 2004 and 2005, respectively. The impairment charges during 2004 and 2005 resulted from our estimation that the operating environment, conditions and performance of certain of our entities could no longer support the goodwill balances associated with them. Impairment must be reflected

when the value of a given business unit in excess of its tangible net assets falls below the goodwill asset balance carried for that unit on the Company’s books. If other business units have had increases in the value of their respective goodwill balances, such increases may not be recorded under SFAS No. 142. Accordingly, such increases may not be netted against impairments at other business units.

Interest Expense, Net—The decrease in interest expense, net is a result of payments on the term loan throughout 2004 and 2005 thereby reducing and eliminating our average debt outstanding, and interest income earned from higher cash balances in the current year. See “Liquidity and Capital Resources” for a detail of the components of interest expense, net for 2004 and 2005.

Write off of debt costs—The second quarter of 2005 includes a non-cash write off of $0.9 million of deferred financing costs resulting from the replacement of our previous credit facility.

Other Income (Expense)—Other expense was $0.4 million for the 2004 and other income was $0.1 million for 2005. Other expense for 2004 includes losses of $0.4 million resulting from mark-to-market adjustments on a warrant with a third-party to buy shares of our stock. The warrant also carried a put obligation. This warrant was exercised in October 2004. This exercise also terminated the related put obligation. As a result, there were no further mark-to-market adjustments to income associated with them.

Income Tax Expense—Our effective tax rate associated with results from continuing operations was (597.7)%. Excluding effects of the goodwill impairment charge, our 2005 effective tax rate was 44.2% as compared to 37.9% in 2004. Our 2004 rate is lower than usual due to an increase in the fourth quarter of 2004 in our estimate of the amount of future state taxable income we will have against which we can apply state tax loss carryforwards. This change in estimate resulted in a reduction in our allowance against state-level deferred tax assets. Our effective tax rate is generally higher than statutory rates because of the effect of certain expenses that are not deductible for tax purposes. In addition, adjustments to tax reserves are analyzed and adjusted quarterly as events occur to warrant such changes. Adjustments to tax reserves are a component of the effective tax rate.

During 2004, the American Jobs Creation Act of 2004 was signed into law. The primary effect of this legislation will be to permit us to claim a deduction for 3% of earnings related to certain of our construction-related activities beginning in 2005. This deduction may decrease our effective tax rate. We currently estimate that our effective tax rate for 2006 will be between 41% and 45%.

Discontinued Operations—On December 31, 2005, we sold 2 operations to Automated Logic Corporation and Automated Logic Contracting Services, Inc. (together, “ALC”) for approximately $22.9 million in cash, net of transaction costs and a purchase price adjustment based upon the closing balance sheet for the transferred assets. We realized an aggregate gain of $9.8 million, including related tax expense, in connection with this sale. The receivable related to this sale was paid during the first quarter of 2006. The after-tax income of these companies of $1.3 million in both 2004 and 2005, has been reported in discontinued operations under “Operating income (loss), net of applicable income taxes.

In 2005, we also sold 2 small operating companies in separate transactions and shutdown the operations at another small operating company. The after-tax loss of these companies was $2.4 million in 2004 and $1.2 million in 2005, and has been reported in discontinued operations under “Operating income (loss), net of applicable income taxes.” The gain recognized on the sale of these units was $0.1 million, including tax expense, and was reported in discontinued operations under “Estimated gain (loss) on disposition, including income taxes.”

In 2004, we sold a small operating company. The after-tax income of this company for the first six months of 2004 was less than $0.1 million and has been reported in discontinued operations under “Operating results, net of tax.” The loss recognized on the sale of this unit in the second quarter of 2004 was $0.5 million, including tax expense, and was reported in discontinued operations under “Estimated loss on disposition, including income taxes.” This loss primarily resulted from the non-cash write off of goodwill associated with this unit. This goodwill write off was not tax deductible. This loss is partially offset

by an after-tax gain of approximately $0.3 million related to a reduction in reserves associated with discontinued operations from previous years.

Outlook—As noted earlier in this review, while we see signs that industry activity levels are continuing to increase in 2006, our primary emphasis for this year is on margin improvement more so than revenue growth. Our ongoing margin efforts include a focus on improving the results of units that incurred losses or subpar income in 2005, and on intensified project and service performance training at the unit level. Based on these margin improvement efforts and developments, on our increased level of backlog as compared to recent periods, and on our belief that industry and economic conditions are improving, we expect that our full-year 2006 operating results will be better than our 2005 results.

2004 Compared to 2003

Revenues—Revenues increased $32.4 million, or 4.3%, to $778.6 million in 2004 compared to 2003. This gain stemmed primarily from growth in our multi-family activity (approximately $36.0 million), primarily in the Washington D.C. area, Atlanta, New England and Florida, and from the generally improving nonresidential facilities markets in the Sunbelt and at our Iowa operations. These gains were offset to a lesser degree by lower revenues relating to consolidation of certain underperforming operations in Northern and Southern California, Western Colorado and Alabama.

Backlog associated with continuing operations as of December 31, 2004 was $512.8 million, a 46.5% increase from December 31, 2003 backlog of $350.1 million, and a 13.1% increase from September 30, 2004 backlog of $453.5 million. These gains result primarily from strong bookings in the multi-family sector, along with significant new government work in California and education work in Wisconsin and Texas.

Gross Profit—Gross profit increased $4.5 million, or 3.8%, to $122.0 million in 2004 compared to 2003. As a percentage of revenues, historical gross profit for 2003 and 2004 remained flat at 15.7%. This was the result of several offsetting items. We realized significantly lower workers compensation and liability costs (approximately $2.4 million) which we believe result in part from our longstanding emphasis on safety and risk management in our operations. We also saw substantially improved gross profit margins at our Houston-based multi-family operations (approximately $3.6 million) as that unit improved its project selection and management performance while benefiting from healthy multi-family demand in a number of markets. These improvements were offset by (a) wind-down of lower profit activities associated with consolidation of operations in Northern California and in San Diego (approximately $3.4 million), along with related consolidation costs; (b) reduced profitability in our Tennessee operations (approximately $2.1 million) resulting from project margin erosion and a settlement on a project claim; and (c) lower margins associated with larger average project size in our Syracuse and Birmingham operations (approximately $3.1 million).

There has been substantial cost inflation in 2004 in certain commodities that are used in construction activity, including steel, iron, and copper. We estimate that direct purchase of these commodities comprises between 10% and 15% of our average project costs. For some projects we performed in 2004, the actual cost of these commodities was significantly greater than the commodity cost estimates we used when we committed to prices for these projects, which typically was done in 2003 before commodity price inflation became apparent. We estimate that unrecovered commodity inflation had a negative effect of approximately $1.0 million on 2004 gross profit, or 0.1% of revenues, most of which occurred during the second quarter. We began taking steps early in 2004 to reduce future commodity cost exposure, such as early buying of commodities for particular projects, or for general inventory, as well as including escalation and escape provisions in project bids and contracts wherever possible. Following our second quarter impact, we experienced virtually no unrecovered cost inflation in the third and fourth quarters. However, commodity markets remain unsettled, and while we are taking steps as noted above to minimize unrecoverable commodity cost inflation, these steps cannot guarantee that we will avoid all such exposure.

Selling, General and Administrative Expenses (“SG&A”)—SG&A decreased $6.6 million, or 6.1%, to $100.8 million in 2004 compared to 2003, and as a percentage of revenues, declined from 14.4% in 2003 to 13.0% in 2004. These decreases resulted primarily from consolidation of certain operating units (approximately $3.4 million) in San Diego, Salt Lake City, Colorado, and Northern California, along with lower medical costs (approximately $1.2 million) resulting from benefit plan structure changes and favorable claims experience.

Goodwill Impairment—Goodwill impairment charges of $2.7 million and $0.6 million were recorded during the fourth quarters of 2003 and 2004, respectively. The impairment charges during 2003 primarily resulted from changes in operating plans that were identified in the fourth quarter of 2003 for certain of our reporting units as part of our annual budgeting and business planning process. The impairment charge during 2004 resulted from our estimation during the fourth quarter of 2004 that the operating environment, conditions and performance of certain of our entities could no longer support the goodwill balances associated with them.

Restructuring Charges—During the first three quarters of 2003, we recorded restructuring charges of approximately $3.2 million pre-tax. These charges included approximately $1.5 million for severance costs and retention bonuses primarily associated with the curtailment of our energy efficiency marketing activities, a reorganization of our national accounts operations as well as a reduction in corporate personnel. The severance costs and retention bonuses related to the termination of 88 employees, all of whom had left the Company by December 31, 2003. The restructuring charges for this period also included approximately $1.6 million for remaining lease obligations and $0.1 million of other costs recorded in connection with the actions described above.

Interest Expense, Net—Interest expense is significantly lower in 2004 as compared to 2003 as a result of much lower debt levels in 2004 stemming from higher cash balances during 2004, and because the credit facility cost noticeably less in upfront fees when it was established in the fourth quarter of 2003, thereby resulting in lower ongoing amortization of these fees in 2004. See “Liquidity and Capital Resources” for a detail of the components of interest expense, net for 2003 and 2004.

Other Expense (Income)—Other expense was $0.4 million for 2004 and other income was $0.2 million for 2003. Other expense for 2004 includes losses of $0.4 million resulting from mark-to-market adjustments on a warrant that was outstanding with a third party to buy shares of our stock. The warrant also carried a put obligation. This warrant was exercised in October 2004. This exercise also terminated the related put obligation. As a result, there will be no further mark-to-market adjustments relating to this warrant and put subsequent to the third quarter of 2004.

Write-off of Debt Costs and Discount, Net—In the fourth quarter of 2003 we recorded a non-cash write-off of $4.7 million of deferred debt arrangement costs and discount when we terminated our previous credit facility. These amounts were partially offset by a $1.3 million gain associated with the reduction in the value of a warrant and put obligation that arose when the facility terminated in the fourth quarter was originally established. This reduction in the value of the warrant and put obligation resulted from a significant restriction in the holder’s ability to exercise the put provision. This restriction was agreed to by the holder in connection with terminating the related facility. We also reflected a non-cash charge of $0.8 million in the first quarter of 2003 for deferred debt costs that were associated with previously higher levels of capacity under this credit facility. The following table recaps these writeoffs (in thousands):

	2003
Write-off of deferred financing fees and transaction costs	$	3,246
Write-off of discount originally arising from issue of stock warrant and related put to credit facility lender	2,250
Reduction in valuation of warrant and put obligation	(1,324		)
Total	$	4,172

Income Tax Expense (Benefit)—Our effective tax rate associated with results from continuing operations for 2004 was 39.2% as compared to 46.2% in 2003. As noted above, we recorded impairments of goodwill in the fourth quarter of 2004 and 2003. Our 2004 rate is lower than usual due to an increase in the fourth quarter of 2004 in our estimate of the amount of future state taxable income we will have against which we can apply state tax loss carryforwards. This change in estimate resulted in a reduction in our allowance against state-level deferred tax assets. While we regularly evaluate the realizability of deferred tax assets relating to tax losses or benefits we have incurred, it should not be expected that such evaluations will regularly result in decreases to our effective tax. For example, in the more difficult economic and operating environments of recent years including 2003 as noted below, such evaluations have led to increases in our related allowances, and thus increases in our effective tax rate. Excluding the effect of our reduction in state deferred tax allowances, as well as the effect of nondeductible goodwill impairment noted above, our effective rate for 2004 would have been larger.

In the fourth quarter of 2003, our year-to-date pre-tax income from continuing operations turned negative as we recognized significant charges for the write-off of deferred debt arrangement costs and for goodwill impairment. The effective benefit rate on our full year 2003 pre-tax loss further increased over statutory rates as a result of additional tax adjustments in the fourth quarter. These adjustments included benefit for the reversal of tax contingency reserves no longer deemed necessary as a result of an updated review of our tax positions across the jurisdictions in which we do business, offset to a lesser degree by additional reserves against state-level deferred tax assets, and recognition of the effect of the nondeductible portion of the goodwill impairment we recorded in the fourth quarter of 2003.

Discontinued Operations—Individual Sales of Operating Companies—During 2004 and 2003, we sold four small operating companies in separate transactions. The after-tax income of these companies has been reported in discontinued operations under “Operating results, net of tax.” Losses we recognized on the sales of these units have been reported in discontinued operations under “Estimated gain (loss) on disposition, including tax.” These losses primarily resulted from the non-cash writeoff of goodwill associated with these units. These goodwill writeoffs were not tax deductible. Additionally, the operating results of the companies sold in 2005, as discussed above, have been presented in discontinued operations for 2003 and 2004.

Discontinued Operations—Sale of Companies to Emcor—On March 1, 2002, we sold 19 operations to Emcor Group. The total purchase price was $186.25 million, including the assumption by Emcor of approximately $22.1 million of subordinated notes to former owners of certain of the divested companies. As of December 31, 2004, we have realized an aggregate loss of $10.9 million, including related tax expense, in connection with the sale of these operations, substantially all of which was recorded in 2002. As a result of the adoption of SFAS No. 142, “Goodwill and Other Intangible Assets,” we also recognized a goodwill impairment charge related to these operations of $32.4 million, net of tax benefit, as of January 1, 2002.

There are ongoing open matters relating to this transaction that we continue to address with Emcor. We do not believe these open matters, either individually or in the aggregate, will have a material effect on our financial position when ultimately resolved. We maintain reserves for these matters, net of amounts receivable from escrow that we believe will ultimately be applied in settling these matters. During the second quarter of 2004, we concluded that the related reserves should be reduced by $0.3 million, net of tax. Additionally, during the fourth quarter of 2004, we reduced these reserves by $0.2 million, net of tax. These amounts are reflected in discontinued operations in 2004 as a reduction in the estimated loss on disposition of discontinued operations.

Free cash flow	$	21,534		$	21,731		$	31,954

Cash Flow—We define free cash flow as cash provided by operating activities excluding items related to sales of businesses, less customary capital expenditures, plus the proceeds from asset sales. Positive free cash flow represents funds available to invest in significant operating initiatives, to acquire other companies, or to reduce a company’s outstanding debt or equity. If free cash flow is negative, additional debt or equity is generally required to fund the outflow of cash. Free cash flow may be defined differently by other companies.

Our business does not require significant amounts of investment in long-term fixed assets. The substantial majority of the capital used in our business is working capital that funds our costs of labor and installed equipment deployed in project work until our customers pay us. Customary terms in our industry allow customers to withhold a small portion of the contract price until after we have completed the work, typically for six months. Amounts withheld under this practice are known as retention or retainage. Our average project duration together with typical retention terms generally allow us to complete the realization of revenue and earnings in cash within one year. Accordingly, we believe free cash flow, by encompassing both profit margins and the use of working capital over our approximately one year working capital cycle, is an effective measure of operating effectiveness and efficiency. We have included free cash flow information here for this reason, and because we are often asked about it by third parties evaluating the Company. However, free cash flow is not considered under generally accepted accounting principles to be a primary measure of an entity’s financial results, and accordingly free cash flow should not be considered an alternative to operating income, net income, or amounts shown in our consolidated statements of cash flows as determined under generally accepted accounting principles.

For the year ended December 31, 2005, we had free cash flow of $32.0 million as compared to $21.7 million in 2004. This increase resulted primarily from increased profitability, net of a slight increase in capital expenditures.

For the year ended December 31, 2004, free cash flow of $21.7 million was essentially unchanged from $21.5 million in 2003. This resulted primarily from increased profitability net of a modest increase in capital expenditures in 2004 as compared to 2003. Excluding taxes related to the sale of businesses, we reduced working capital by about the same amounts in both 2003 and 2004, thus improving our working capital efficiency in both periods.

Credit Facility—On June 30, 2005, the Company entered into a senior credit facility (the “Facility”) provided by a syndicate of banks. The Facility consists of a $75.0 million revolving credit facility which is available for borrowings and letters of credit. As of December 31, 2005, the total of the Facility was $75.0

million, with no outstanding borrowings, $22.1 million in letters of credit outstanding, and $52.9 million of credit available. The facility will expire on June 30, 2009.

The credit facility that preceded our current one was in place from December 2003 to June 2005. Our next previous credit facility had been in place from October 2002 to December 2003. Interest expense for 2003, 2004 and 2005 included the following primary elements (in thousands):

	2003		2004		2005
Interest expense on borrowings, and unused commitment fees	$	1,397	$	704	$	391
Letter of credit fees	512		443		389
Amortization of deferred debt arrangement costs and discount	1,496		419		295
Mark-to-market adjustments on derivatives	488		—		—
Total	$	3,893	$	1,566	$	1,075

When our previous credit facilities were reduced in size or terminated, corresponding amounts of deferred debt arrangement costs were written off. The largest of these write-offs occurred in the fourth quarter of 2003 when we terminated the preceding facility, which had been in place just over one year. This write-off was partially offset by a $1.3 million gain associated with the reduction in the value of a stock warrant and related put obligation that arose when the facility terminated in the fourth quarter was originally established. This reduction in the value of the warrant and put obligation resulted from a significant restriction in the holder’s ability to exercise the put provision. This restriction was agreed to by the holder in connection with terminating the related credit facility. These charges are reported as “Write-off of debt costs and discount, net” in our consolidated statement of operations, and include the following primary elements (in thousands):

	2003			2004			2005
Write-off of deferred financing fees and transaction costs	$	3,246			$	—	$	870
Write-off of discount originally arising from issue of stock warrant and related put to credit facility lender	2,250				—		—
Reduction in valuation of warrant and put obligation	(1,324		)		—		—
Total	$	4,172			$	—	$	870

The warrant was exercised in the fourth quarter of 2004. As a result of the exercise, the related put rights associated with the warrant terminated.

Excluding the amortization of debt financing and arrangement costs, we estimate that the interest rate applicable to the borrowings under the Facility would be approximately 6.39% as of December 31, 2005. Commitment fees of 0.25% per annum are also payable on the portion of the Facility capacity not in use for borrowings or letters of credit at any given time. See Note 9 of the “Notes to Consolidated Financial Statements” for a detailed discussion of the interest rates and fees associated with the Facility.

Our borrowings and letters of credit capacity under the Revolving Loan portion of the Facility at any given time is $75.0 million less borrowings and letters of credit outstanding, subject to a borrowing base. The borrowing base is defined under the Facility as 65% of the following: total trade receivables including costs and estimated earnings in excess of billings, less allowances for doubtful accounts, less receivables related to projects that are subject to payment or performance bonds. The borrowing base as of December 31, 2005 was $96.2 million. This borrowing base is substantially greater than the current $75.0 million face-value limit of the Facility. We do not expect that this borrowing base provision will limit credit available under the Facility in the foreseeable future.

The Facility contains financial covenants defining various financial measures and the levels of these measures with which the Company must comply, as discussed below under Covenants and Restrictions. Covenant compliance is measured as of each quarter-end. While the Facility’s financial covenants do not specifically govern capacity under the Facility, if the Company’s debt level under the Facility at a quarter-end covenant compliance measurement date were to cause the Company to violate the Facility’s debt-to-Credit Facility Adjusted EBITDA covenant (described in more detail below), the Company’s borrowing capacity under the Facility could be restricted by the lenders. Accordingly, available capacity amounts shown below are presented both on a financial covenant basis and on a Facility face value basis.

Amounts Outstanding:
Revolving loan		$	—
Other non-Facility debt		—
Total debt		$	—
Letters of credit		$	22,139

Unused Revolving Loan and letter of credit capacity based on quarter-end debt-to-Credit Facility Adjusted EBITDA covenant		$	52,861

The Facility contains financial covenants defining various financial measures and the levels of these measures with which the Company must comply. Covenant compliance is assessed as of each quarterend. Credit Facility Adjusted EBITDA is defined under the Facility for financial covenant purposes as net earnings for the four quarters ending as of any given quarterly covenant compliance measurement date, plus the corresponding amounts for (a) interest expense; (b) income taxes; (c) depreciation and amortization; and (d) other non-cash charges. The following is a reconciliation of Credit Facility Adjusted EBITDA to net loss (in thousands):

Net loss	$	(6,226	)
Income taxes—continuing operations and discontinued operations	21,133
Interest expense, net	309
Write off of debt cost	870
Depreciation and amortization expense	4,818
Goodwill impairment—continuing operations and discontinued operations	33,877
Credit Facility Adjusted EBITDA	$	54,781

The Facility’s principal financial covenants include:

Fixed Charge Coverage Ratio—The Facility requires that the ratio of Credit Facility Adjusted EBITDA, less non-financed capital expenditures, tax provision, dividends and amounts used to repurchase stock to the sum of interest expense and scheduled principal payments be at least 1.50. Capital expenditures, tax provision, dividends and stock repurchase payments are defined under the Facility for purposes of this covenant to be amounts for the four quarters ending as of any given quarterly covenant compliance measurement date. Interest expense is defined under the Facility as interest expense for the

four quarters ending as of any given quarterly covenant compliance measurement date, excluding corresponding twelve-month amounts for (a) amortization of deferred debt arrangement costs; and (b) mark-to-market interest expense. Scheduled principal payments for this ratio are also measured for the twelve months ending as of any given quarterly covenant compliance measurement date. The Company’s fixed charge coverage ratio as of December 31, 2005 as measured under this covenant was 35.84 as compared to a minimum covenant requirement of 1.50.

Tangible Net Worth—The Facility requires that the Company’s tangible net worth not be less than the sum of (a) $100.5 million; (b) 50% of net income earned beginning April 1, 2005; and (c) the net proceeds of any equity transactions. For purposes of this ratio, the Facility defines tangible net worth as stockholders’ equity less the book value of the following intangible assets: goodwill, patents, copyrights, licenses, franchises, trade names, trade secrets, and operating leases. The Facility also provides that for purposes of this ratio, net income excludes any goodwill impairment charges. The Company’s tangible net worth as of December 31, 2005 as measured under this covenant was $150.6 million, as compared to a covenant minimum of $116.9 million.

Debt to Credit Facility Adjusted EBITDA—The Facility requires that the Company’s ratio of debt to Credit Facility Adjusted EBITDA not exceed 2.5. The Company’s debt-to-Credit Facility Adjusted EBITDA ratio as of December 31, 2005 as measured under this covenant was zero because the Company has no debt.

Capital Expenditures—The Facility limits capital expenditures to $20.0 million per year. The Company’s capital expenditures during the year ended December 31, 2005 were $6.2 million.

Other Restrictions—The Facility limits payment of dividends and repurchase of shares by the Company to a combined maximum of $20.0 million per year, and otherwise limits non-Facility debt, capital lease obligations, acquisitions, investments, and sales of assets. Debt under the Facility is classified as long-term as the facility will expire in June 2009. During the fourth quarter of 2005, the Company amended the Facility to permit the sale of substantially all of the assets of two subsidiaries. That sale is discussed in Note 4 “Discontinued Operations.” The amendment also provides additional flexibility for us to purchase our common shares.

Off-Balance Sheet Arrangements and Other Commitments—As is common in our industry, we have entered into certain off-balance sheet arrangements in the ordinary course of business that result in risks not directly reflected in our balance sheets. Our most significant off-balance sheet transactions include liabilities associated with noncancelable operating leases. We also have other off-balance sheet obligations involving letters of credit and surety guarantees.

We enter into noncancelable operating leases for many of our facility, vehicle and equipment needs. These leases allow us to conserve cash by paying a monthly lease rental fee for use of facilities, vehicles and equipment rather than purchasing them. At the end of the lease, we have no further obligation to the lessor. If we decide to cancel or terminate a lease before the end of its term, we would typically owe the lessor the remaining lease payments under the term of the lease.

Certain of our vendors require letters of credit to ensure reimbursement for amounts they are disbursing on our behalf, such as to beneficiaries under our self-funded insurance programs. We have also occasionally used letters of credit to guarantee performance under our contracts and to ensure payment to our subcontractors and vendors under those contracts. The letters of credit we provide are actually issued by our lenders through the Facility as described above. A letter of credit commits the lenders to pay specified amounts to the holder of the letter of credit if the holder demonstrates that we have failed to perform specified actions. If this were to occur, we would be required to reimburse the lenders. Depending on the circumstances of such a reimbursement, we may also have to record a charge to earnings for the reimbursement. Absent a claim, there is no payment or reserving of funds by us in connection with a letter

of credit. However, because a claim on a letter of credit would require immediate reimbursement by us to our lenders, letters of credit are treated as a use of the Facility’s capacity just the same as actual borrowings. Claims against letters of credit are rare in our industry. To date we have not had a claim made against a letter of credit that resulted in payments by a lender or by us. We believe that it is unlikely that we will have to fund claims under a letter of credit in the foreseeable future.

Many customers, particularly in connection with new construction, require us to post performance and payment bonds issued by a financial institution known as a surety. If we fail to perform under the terms of a contract or to pay subcontractors and vendors who provided goods or services under a contract, the customer may demand that the surety make payments or provide services under the bond. We must reimburse the sureties for any expenses or outlays they incur. To date, we are not aware of any losses to our sureties in connection with bonds the sureties have posted on our behalf, and we do not expect such losses to be incurred in the foreseeable future.

Surety market conditions are currently challenging as a result of significant losses incurred by many sureties in recent periods, both in the construction industry as well as in certain larger corporate bankruptcies. As a result, less bonding capacity is available in the market and terms have become more restrictive. Further, under standard terms in the surety market, sureties issue bonds on a project-by-project basis, and can decline to issue bonds at any time. Historically, approximately 30% of our business has required bonds. While we have enjoyed a longstanding relationship with our primary surety and we have added another surety to further support our bonding needs, current market conditions as well as changes in our sureties’ assessment of our operating and financial risk could cause our sureties to decline to issue bonds for our work. If that were to occur, our alternatives include doing more business that does not require bonds, posting other forms of collateral for project performance such as letters of credit or cash, and seeking bonding capacity from other sureties. We would likely also encounter concerns from customers, suppliers and other market participants as to our creditworthiness. While we believe our general operating and financial characteristics, including a significant amount of cash on our balance sheet, would enable us to ultimately respond effectively to an interruption in the availability of bonding capacity, such an interruption would likely cause our revenues and profits to decline in the near term.

The following recaps the future maturities of our contractual obligations as of December 31, 2005 (in thousands):

	Twelve Months Ended December 31,
	2006		2007		2008	2009	2010	Thereafter		Total
Operating lease obligations	$	8,357	$	7,311	$5,610	$4,199	$1,655		$5,201	$32,333

Absent any significant commitments of capital for items such as capital expenditures, acquisitions, dividends and share repurchases, it is reasonable to expect the Company to continue to maintain excess cash on its balance sheet. Therefore, we assumed that the Company would continue its current status of not utilizing any borrowings under its revolving loan.

As of December 31, 2005 we also have $22.1 million of letter of credit commitments, all of which expire in 2006. The substantial majority of these letters of credit are posted with insurers who disburse funds on our behalf in connection with our worker’s compensation, auto liability and general liability insurance program. These letters of credit provide additional security to the insurers that sufficient financial resources will be available to fund claims on our behalf, many of which develop over long periods of time, should we ever encounter financial duress. Posting of letters of credit for this purpose is a common practice for entities that manage their self-insurance programs through third-party insurers as we do. While these letter of credit commitments expire in 2006, we expect nearly all of them, particularly those supporting our insurance programs, will be renewed annually.

Other than the operating lease obligations noted above, we have no significant purchase or operating commitments outside of commitments to deliver equipment and provide labor in the ordinary course of performing project work.

Outlook—We have generated positive net free cash flow for the last five calendar years, most of which occurred during challenging economic and industry conditions. We also expect to have no debt, significant borrowing capacity under our credit facility, and substantial uncommitted cash balances. We believe these factors will provide us with sufficient liquidity to fund our operations for the foreseeable future.

Seasonality and Cyclicality

The HVAC industry is subject to seasonal variations. Specifically, the demand for new installation and replacement is generally lower during the winter months (the first quarter of the year) due to reduced construction activity during inclement weather and less use of air conditioning during the colder months. Demand for HVAC services is generally higher in the second and third calendar quarters due to increased construction activity and increased use of air conditioning during the warmer months. Accordingly, we expect our revenues and operating results generally will be lower in the first and fourth calendar quarters.

Historically, the construction industry has been highly cyclical. As a result, our volume of business may be adversely affected by declines in new installation and replacement projects in various geographic regions of the United States.

New Accounting Pronouncements

In December 2004, the Financial Accounting Standards Board (“FASB”) issued SFAS 123R “Share-Based Payment.” SFAS 123R addresses the accounting for share-based payments to employees, including grants of employee stock options. Under the new standard, companies will no longer be able to account for share-based compensation transactions using the intrinsic value method in accordance with Accounting Principles Board (APB) Opinion No. 25, “Accounting for Stock Issued to Employees”. Instead, companies will be required to account for such transactions using a fair-value method and recognize the expense in the consolidated statement of income. We expect to use the Black-Scholes option pricing model to determine the fair value of our stock-based awards. SFAS 123R requires companies to use either the modified-prospective or modified-retrospective transition method. We will use the modified-prospective transition method. Under this method, compensation cost is recognized for all awards granted, modified or settled after the adoption date as well as for any awards that were granted prior to the adoption date for which the requisite service has not yet been rendered. We adopted SFAS 123R on January 1, 2006.

As permitted by Statement 123, we currently account for share-based payments to employees using Opinion 25’s intrinsic value method and, as such, generally recognize no compensation cost for employee stock options in our results of operations. Accordingly, the adoption of Statement 123(R)’s fair value method will have a significant impact on our reported results of operations, although it will have no impact on our cash flows. The impact of adoption of Statement 123(R) cannot be predicted at this time because it will depend on levels of share-based payments granted in the future. However, had we adopted Statement 123(R) in prior periods, the impact of that standard would have approximated the impact of Statement 123 as described in the disclosure of pro forma net income and earnings per share in Note 2 to our consolidated financial statements. Statement 123(R) also requires the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing cash flow, rather than as an operating cash flow as required under current literature. This requirement will reduce net operating cash flows and increase net financing cash flows in periods after adoption. While we cannot estimate what those amounts will be in the future (because they depend on, among other things, when employees exercise stock options), the amount of operating cash flows recognized in prior periods for such tax benefits were $0.2 million, $0.7 million and $1.3 million in 2003, 2004 and 2005, respectively.

ITEM 7-A. Quantitative and Qualitative Disclosures about Market Risk

We are exposed to market risk primarily related to potential adverse changes in interest rates as discussed below. Management is actively involved in monitoring exposure to market risk and continues to develop and utilize appropriate risk management techniques. We are not exposed to any other significant financial market risks including commodity price risk (except as discussed in “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations”), foreign currency exchange risk or interest rate risks from the use of derivative financial instruments. The Company does not use derivative financial instruments.

We have limited exposure to changes in interest rates due to our lack of indebtedness for borrowed money. We have a debt facility under which we may borrow funds in the future. We do not currently foresee any borrowing needs.

COMFORT SYSTEMS USA, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2005

1. Business and Organization

Comfort Systems USA, Inc., a Delaware corporation (“Comfort Systems” and collectively with its subsidiaries, the “Company”), is a national provider of comprehensive heating, ventilation and air conditioning (“HVAC”) installation, maintenance, repair and replacement services within the mechanical services industry. The Company operates primarily in the commercial, industrial and institutional HVAC markets, and performs most of its services within office buildings, retail centers, apartment complexes, manufacturing plants, and healthcare, education and government facilities. In addition to standard HVAC services, the Company provides specialized applications such as building automation control systems, fire protection, process cooling, electronic monitoring and process piping. Certain locations also perform related activities such as electrical service and plumbing. Approximately 56% of the Company’s consolidated 2005 revenues are attributable to installation of systems in newly constructed facilities, with the remaining 44% attributable to maintenance, repair and replacement services. The following service activities account for the Company’s consolidated 2005 revenues: HVAC—75%, plumbing—16%, building automation control systems—4%, and other—5%. These service activities are within the mechanical services industry which is the single industry segment served by Comfort Systems.

2. Summary of Significant Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of Comfort Systems and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.

Cash Flow Information

The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.

Cash paid for interest for continuing operations in 2003, 2004 and 2005 was approximately $1.9 million, $0.9 million, and $0.8 million, respectively. Cash paid for income taxes for continuing operations in 2003, 2004 and 2005 was approximately $2.0 million, $6.3 million and $13.0 million, respectively. Cash paid for income taxes for discontinued operations in 2003, 2004 and 2005 was approximately $9.1 million, $0.5 million and $0.1 million, respectively. The cash tax payments for 2003 include approximately $10.4 million associated with the sale in 2002 of 19 operations to Emcor Group, Inc. (“Emcor”). These taxes are included in the caption “Taxes paid related to the sale of businesses” in the accompanying Consolidated Statement of Cash Flows.

In 2005, the Company paid a cash dividend of $0.025 per share, for total cash dividends of $1.0 million. There were no dividends paid in 2003 and 2004.

Inventories

Inventories consist of parts and supplies that the Company purchases and holds for use in the ordinary course of business and are stated at the lower of cost or market using the first-in, first-out method.

Property and Equipment

Property and equipment are stated at cost, and depreciation is computed using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are capitalized and amortized over the lesser of the expected life of the lease or the estimated useful life of the asset.

Expenditures for repairs and maintenance are charged to expense when incurred. Expenditures for major renewals and betterments, which extend the useful lives of existing equipment, are capitalized and depreciated over the remaining useful life of the equipment. Upon retirement or disposition of property and equipment, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is recognized in “Loss (gain) on sale of assets” in the statement of operations.

Goodwill

Goodwill represents the excess of the aggregate purchase price paid by the Company in acquisitions over the fair value of the net tangible and intangible assets acquired.

Long-Lived Assets

Long-lived assets are comprised principally of goodwill, property and equipment, and deferred income tax assets. The Company periodically evaluates whether events and circumstances have occurred that indicate that the remaining balances of these assets may not be recoverable. The Company uses estimates of future income from operations and cash flows, as well as other economic and business factors, to assess the recoverability of these assets.

Revenue Recognition

Approximately 85% of the Company’s revenues were earned on a project basis and recognized through the percentage of completion method of accounting. Under this method as provided by American Institute of Certified Public Accountants Statement of Position 81-1, “Accounting for Performance of Construction-Type and Certain Production-Type Contracts,” (“SOP 81-1”) contract revenue recognizable at any time during the life of a contract is determined by multiplying expected total contract revenue by the percentage of contract costs incurred at any time to total estimated contract costs. More specifically, as part of the negotiation and bidding process in which the Company engages in connection with obtaining installation contracts, the Company estimates its contract costs, which include all direct materials (exclusive of rebates), labor and subcontract costs and indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs and depreciation costs. These contract costs are included in the Company’s results of operations under the caption “Cost of services.” Then, as the Company performs under those contracts, such costs are measured as incurred, compared to total estimated costs to complete the contract, and a corresponding proportion of contract revenue is recognized. Labor costs are considered to be incurred as the work is performed. Subcontractor labor is recognized as the work is performed, but is generally subjected to approval as to milestones or other evidence of completion. Non-labor project cost consists of purchased equipment, prefabricated materials and other materials. Purchased equipment on the Company’s projects are substantially all produced to job specifications and are a value added element to the Company’s work. The costs are considered to be incurred when title is transferred to the Company, which typically is upon delivery to the work site. Prefabricated materials, such as ductwork and piping, are generally performed at the Company’s shops and recognized as contract costs when fabricated for the unique specifications of the job. Other materials cost are not significant and are generally recorded when delivered to the work site. This measurement and comparison process requires updates to the estimate of total costs to complete the contract, and these updates may include subjective assessments. For certain contracts where the Company performs multiple construction-related activities such as HVAC, plumbing, fire protection and other services, the contract may be segmented for revenue recognition purposes into

separate projects if specific criteria are met under SOP 81-1. The contract price is assigned to the different services based upon the relative value of each service to the expected total contract revenue.

Project contracts typically provide for a schedule of billings or invoices to the customer based on reaching agreed-upon milestones or as the Company incurs costs. The schedules for such billings usually do not precisely match the schedule on which costs are incurred. As a result, contract revenues recognized in the statement of operations can and usually do differ from amounts that can be billed or invoiced to the customer at any point during the contract. Amounts by which cumulative contract revenues recognized on a contract as of a given date exceed cumulative billings to the customer under the contract are reflected as a current asset in the Company’s balance sheet under the caption “Costs and estimated earnings in excess of billings.” Amounts by which cumulative billings to the customer under a contract as of a given date exceed cumulative contract revenues recognized on the contract are reflected as a current liability in the Company’s balance sheet under the caption “Billings in excess of costs and estimated earnings.”

The percentage of completion method of accounting is also affected by changes in job performance, job conditions, and final contract settlements. These factors may result in revisions to estimated costs and, therefore, revenues. Such revisions are frequently based on further estimates and subjective assessments. The effects of these revisions are recognized in the period in which the revisions are determined. When such revisions lead to a conclusion that a loss will be recognized on a contract, the full amount of the estimated ultimate loss is recognized in the period such a conclusion is reached, regardless of the percentage of completion of the contract.

Revisions to project costs and conditions can give rise to change orders under which the customer agrees to pay additional contract price. Revisions can also result in claims the Company might make against the customer to recover project variances that have not been satisfactorily addressed through change orders with the customer. Except in certain circumstances, the Company does not recognize revenues or margin based on change orders or claims until they have been agreed upon with the customer. The amount of revenue associated with unapproved change orders and claims is currently immaterial. Variations from estimated project costs could have a significant impact on the Company’s operating results, depending on project size, and the recoverability of the variation via additional customer payments.

Revenues associated with maintenance, repair and monitoring services and related contracts are recognized as services are performed.

Accounts Receivable

Accounts receivable include amounts billed to customers under retention or retainage provisions in construction contracts. Such provisions are standard in the Company’s industry and usually allow for a small portion of progress billings or the contract price to be withheld by the customer until after the Company has completed work on the project, typically for a period of six months. Based on the Company’s experience with similar contracts in recent years, billings for such retention balances at each balance sheet date are finalized and collected within the subsequent year. Retention balances at December 31, 2004 and 2005 are $35.7 million and $45.7 million, respectively, and are included in accounts receivable.

The carrying value of the Company’s receivables, net of the allowance for doubtful accounts, represents their estimated net realizable value. The Company estimates its allowance for doubtful accounts based upon the creditworthiness of its customers, prior collection history, ongoing relationships with its customers, the aging of past due balances, the Company’s lien rights, if any, in the property where the Company performed the work, and the availability, if any, of payment bonds applicable to the contract. The receivables are written off when they are deemed to be uncollectible.

Self-Insurance Liabilities

The Company is substantially self-insured for worker’s compensation, employer’s liability, auto liability, general liability and employee group health claims, in view of the relatively high per-incident deductibles the Company absorbs under its insurance arrangements for these risks. Losses up to deductible amounts are estimated and accrued based upon known facts, historical trends and industry averages. Loss estimates associated with the larger and longer-developing risks—worker’s compensation, auto liability and general liability—are reviewed by a third-party actuary quarterly. The Company’s self-insurance arrangements are further discussed in Note 12 “Commitments and Contingencies.”

Warranty Costs

The Company typically warrants labor for the first year after installation on new HVAC systems. The Company generally warrants labor for 30 days after servicing of existing HVAC systems. A reserve for warranty costs is estimated and recorded based upon the historical level of warranty claims and management’s estimate of future costs.

Income Taxes

The Company files a consolidated return for federal income tax purposes. Income taxes are provided for under the liability method in accordance with SFAS No. 109, “Accounting for Income Taxes,” which takes into account differences between financial statement treatment and tax treatment of certain transactions. Deferred tax assets represent the tax effect of activity that has been reflected in the financial statements but which will not be deductible for tax purposes until future periods. Deferred tax liabilities represent the tax effect of activity that has been reflected in the financial statements but which will not be taxable until future periods.

The Company regularly evaluates valuation allowances established for deferred tax assets for which future realization is uncertain. The Company performs this evaluation each quarter. Estimations of required valuation allowances include estimates of future taxable income. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which the activity underlying these assets becomes deductible. The Company considers projected future taxable income and tax planning strategies in making this assessment. If actual future taxable income differs from the estimates, the Company may not realize deferred tax assets to the extent it has estimated.

New Accounting Pronouncements

In December 2004, the Financial Accounting Standards Board (“FASB”) issued Statement 123R “Share-Based Payment.” Statement 123R addresses the accounting for share-based payments to employees, including grants of employee stock options. Under the new standard, companies will no longer be able to account for share-based compensation transactions using the intrinsic value method in accordance with Accounting Principles Board (APB) Opinion No. 25, “Accounting for Stock Issued to Employees.” Instead, companies will be required to account for such transactions using a fair-value method and recognize the expense in the consolidated statement of operations. The Company expects to use the Black-Scholes option pricing model to determine the fair value of its stock-based awards. Statement 123R requires companies to use either the modified-prospective or modified-retrospective transition method. The Company will use the modified-prospective transition method. Under this method, compensation cost is recognized for all awards granted, modified or settled after the adoption date as well as for any awards that were granted prior to the adoption date for which the requisite service has not yet been rendered. The company adopted Statement 123R on January 1, 2006.

The Company currently accounts for share-based payments to employees using Opinion 25’s intrinsic value method and, as such, generally recognizes no compensation cost for employee stock options in its

statement of operations. Accordingly, the adoption of Statement 123R’s fair value method will have a significant impact on the Company’s reported results of operations, although it will have no impact on the Company’s cash flows. The impact of adoption of Statement 123R cannot be predicted at this time because it will depend on levels of share-based payments granted in the future. However, had the Company adopted Statement 123R in prior periods, the impact of that standard would have approximated the impact of Statement 123 as described in the disclosure of pro forma net income and earnings per share in Note 2 to the Company’s consolidated financial statements. Statement 123R also requires the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing cash flow, rather than as an operating cash flow as required under current literature. This requirement will reduce net operating cash flows and increase net financing cash flows in periods after adoption. While the Company cannot estimate what those amounts will be in the future (because they depend on, among other things, when employees exercise stock options), the amount of operating cash flows recognized in prior periods for such tax benefits were $0.2 million, $0.7 million and $1.3 million in 2003, 2004 and 2005, respectively.

Segment Disclosure

Comfort Systems’ activities are within the mechanical services industry, which is the single industry segment served by the Company. Under SFAS No. 131, “Disclosures About Segments of an Enterprise and Related Information,” each operating subsidiary represents an operating segment and these segments have been aggregated, as no individual operating unit is material and the operating units meet a majority of SFAS No. 131’s aggregation criteria.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires the use of estimates and assumptions by management in determining the reported amounts of assets and liabilities, revenues and expenses, and disclosures regarding contingent assets and liabilities. Actual results could differ from those estimates. The most significant estimates used in the Company’s financial statements affect revenue and cost recognition for construction contracts, the allowance for doubtful accounts, self-insurance accruals, deferred tax assets, warranty accruals, and the quantification of fair value for reporting units in connection with the Company’s goodwill impairment testing.

Concentrations of Credit Risk

The Company provides services in a broad range of geographic regions. The Company’s credit risk primarily consists of receivables from a variety of customers including general contractors, property owners and developers, and commercial and industrial companies. The Company regularly reviews its accounts receivable and estimates an allowance for uncollectible amounts. The Company has a diverse customer base, with no single customer accounting for more than 3% of consolidated 2005 revenues.

Financial Instruments

The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, receivables from related parties, other receivables, accounts payable, a line of credit, notes payable, and long-term debt. The Company believes that the carrying values of these instruments on the accompanying balance sheets approximate their fair values.

Stock-Based Compensation

The Company accounts for its stock-based compensation using the intrinsic value method under Opinion 25. Under this accounting method, no expense in connection with the Company’s stock option plans is recognized in the consolidated statements of operations when the exercise price of the stock options is greater than or equal to the value of the Common Stock on the date of grant. In October 1995, the FASB issued Statement 123, which requires that if a company accounts for stock-based compensation in accordance with Opinion 25, the company must also disclose the effects on its results of operations as if an estimate of the value of stock-based compensation at the date of grant was recorded as an expense in the company’s statement of operations. These effects for the Company are as follows (in thousands, except per share data):

	2003			2004			2005
Net Income (Loss) as reported	$	(5,579	)	$	10,713		$	(6,226	)
Add: Stock-based compensation included in reported net income, net of tax	114			242			337
Less: Compensation expense per SFAS No. 123, net of tax	(2,394		)	(1,431		)	(1,028		)
Pro forma Net Income (Loss)	$	(7,859	)	$	9,524		$	(6,917	)
Net Income (Loss) per share—Basic
Net Income (Loss) per share as reported	$	(0.15	)	$	0.28		(0.16		)
Pro forma Net Income (Loss) per share	$	(0.21	)	$	0.25		(0.18		)
Net Income (Loss) per share—Diluted

Pro forma Net Income (Loss) per share	$	(0.23	)	$	0.24		(0.18		)

Stock Option Plans—The effects of applying SFAS No. 123 in the pro forma disclosure may not be indicative of future amounts, as additional option awards in future years are anticipated. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model with the following assumptions:

	2003	2004	2005
Expected dividend yield	0.00%	0.00%	0.00%
Expected stock price volatility	62.24%	61.24%	61.23% - 63.99%
Risk-free interest rate	2.94% - 3.85%	3.96% - 4.38%	3.91% - 4.31%
Expected life of options	7 years	7 years	7 years

Restricted Stock—The Company has awarded shares of restricted stock to members of senior management, as discussed in Note 13, “Stockholders’ Equity.” The weighted-average fair value of shares awarded during 2004 and 2005 were $6.10 and $5.58, respectively. The Company did not grant any shares of restricted stock in 2003.

Reclassifications

Certain reclassifications have been made in prior period financial statements to conform to current period presentation. These reclassifications have not resulted in any changes to previously reported net income for any periods.

3. Acquisition

On January 17, 2005, the Company completed the acquisition of Granite State Plumbing & Heating (“Granite”), an HVAC contractor located near Manchester, New Hampshire. This acquisition has

increased the Company’s presence in the Northeast, specifically in the Boston region and southern New Hampshire. The total consideration paid in this transaction was approximately $2.9 million, comprised entirely of cash, including cash acquired. The fair value of the tangible net assets acquired exceeded the total consideration paid. As a result, the long-term fixed assets of the acquisition were reduced by this excess amount. The consolidated balance sheet of Comfort Systems includes an allocation of the purchase price to the assets acquired and liabilities assumed based on estimates of fair value. The purchase price was allocated as follows (amounts in thousands):

Accounts receivable, net	$	5,223
Costs and estimated earnings in excess of billings	1,156
Other current assets	284
Property and equipment	210
Less: Accounts payable	(2,983		)
Less: Billings in excess of costs and estimated earnings	(175		)
Less: Other current liabilities	(747		)
Less: Other long-term liabilities	(25		)
Cash paid, including cash acquired	$	2,943

The results of operations of Granite are included in the Company’s consolidated financial statements from January 17, 2005 through December 31, 2005.

4. Discontinued Operations

Sale of Companies to ALC—On December 31, 2005, the Company sold 2 operations to Automated Logic Corporation and Automated Logic Contracting Services, Inc. (together, “ALC”) for approximately $22.9 million in cash, net of transaction costs and a purchase price adjustment based upon the closing balance sheet for the transferred assets. The receivable related to this sale was paid during the first quarter of 2006.

The after-tax income of these companies of $0.9 million, $1.3 million and $1.3 million in 2003, 2004 and 2005, respectively, has been reported in discontinued operations under “Operating income (loss), net of applicable income taxes.” The gain recognized on the sale of these units was $9.8 million, including tax expense, and was reported in discontinued operations under “Estimated gain (loss) on disposition, including income taxes.”

Individual Sales of Operating Companies—From 2003 to 2005, the Company sold 7 small operating companies in separate transactions.

Sale of Companies to Emcor—On March 1, 2002, the Company sold 19 operations to Emcor Group, Inc. (“Emcor”). The total purchase price was $186.25 million, including the assumption by Emcor of approximately $22.1 million of subordinated notes to former owners of certain of the divested companies. The Company has realized an aggregate loss of $10.8 million, including related tax expense, in connection with the sale of these operations. As a result of the adoption of SFAS No. 142, “Goodwill and Other Intangible Assets,” the Company also recognized a goodwill impairment charge related to these operations of $32.4 million, net of tax benefit, as of January 1, 2002.

The transaction with Emcor provided for a post-closing adjustment based on a final accounting, done after the closing of the transaction, of the net assets of the operations that were sold to Emcor. That accounting indicated that the net assets transferred to Emcor were approximately $7 million greater than a target amount that had been agreed to with Emcor. In the second quarter of 2002, Emcor paid the Company that amount, and released $2.5 million that had been escrowed in connection with this element of the transaction.

Of Emcor’s purchase price, $5 million was deposited into an escrow account to secure potential obligations on the Company’s part to indemnify Emcor for future claims and contingencies arising from events and circumstances prior to closing, all as specified in the transaction documents. Of this escrow, $4 million has been applied in determining the Company’s liability to Emcor in connection with the settlement of certain claims as described subsequently in this section. The remaining $1 million of escrow is available for book purposes to apply to any future claims and contingencies in connection with this transaction, and has not been recognized as part of the Emcor transaction purchase price.

The net cash proceeds of approximately $150 million received to date from the Emcor transaction were used to reduce the Company’s debt. The Company paid $10.4 million of taxes related to this transaction in March 2003.

In the fourth quarter of 2002, the Company recognized a charge of $1.2 million, net of tax benefit of $2.7 million, in discontinued operations under “Estimated loss on disposition, including income taxes” in connection with the Emcor transaction. This charge primarily related to a settlement with Emcor for reimbursement of impaired assets and additional liabilities associated with the operations acquired from the Company. The gross amount of the settlement, before application of any escrow amounts or related tax benefits, was $7.9 million. Under this settlement, the Company was released from liability on all other outstanding receivables and issues relating to the profitability of projects that were in process at the time Emcor acquired these operations. The Company applied $4 million of the $5 million general escrow described above to reduce its liability under this settlement. Accordingly, for book purposes, $1.0 million of escrow remains available to apply against future claims that may arise from Emcor in connection with this transaction. The Company recorded a tax benefit of $1.4 million related to the net of the settlement amount and the application of the escrow. In addition, the Company also recognized a separate tax credit of $1.3 million in the fourth quarter of 2002 as a result of lower final tax liabilities in connection with the overall Emcor transaction than were estimated when the transaction originally closed in the first quarter of 2002. These fourth quarter 2002 charges are recapped below along with all other activity related to the Company’s aggregate loss on disposition recognized on the Emcor transaction.

The fourth quarter 2002 settlement with Emcor described above has been funded through $2.7 million of direct payments by the Company in 2003, and by the application of $3.3 million in escrow funds to date.

There are ongoing open matters relating to this transaction that the Company continues to address with Emcor. The Company does not believe these open matters, either individually or in the aggregate, will have a material effect on the Company’s financial position when ultimately resolved. The Company maintains reserves for these matters, net of amounts receivable from escrow that it believes will ultimately be applied in settling these matters. During the second quarter of 2004, the Company concluded that the related reserves should be reduced by $0.3 million, net of tax benefit. Additionally, during the fourth quarter of 2004, the Company reduced these reserves by $0.2 million, net of tax. During the third quarter of 2005, the Company reduced tax reserves by $0.1 million in connection with the resolution of state tax examinations. These amounts are reflected in discontinued operations in 2004 and 2005 in the caption “Estimated gain (loss) on disposition of discontinued operations.”

5. Goodwill

In most businesses the Company has acquired, the value paid to buy the business was greater than the value of specifically identifiable net assets in the business. Under generally accepted accounting principles, this excess is termed goodwill and is recognized as an asset at the time the business is acquired. It is generally expected that future net earnings from an acquired business will exceed the goodwill asset recognized at the time the business is bought. Under previous generally accepted accounting principles, goodwill was required to be amortized, or regularly charged to the Company’s operating results in its statement of operations.

SFAS No. 142, “Goodwill and Other Intangible Assets” requires companies to assess goodwill asset amounts for impairment each year, and more frequently if circumstances suggest an impairment may have occurred. Impairment must be reflected when the value of a given business unit in excess of its tangible net assets falls below the goodwill asset balance carried for that unit on the Company’s books. If other business units have had increases in the value of their respective goodwill balances, such increases may not be recorded under SFAS No. 142. Accordingly, such increases may not be netted against impairments at other business units.

The Company currently performs its annual impairment testing as of October 1 and any impairment charges resulting from this process are reported in the fourth quarter. The Company segregated its operations into reporting units based on the degree of operating and financial independence of each unit and the Company’s related management of them. These reporting units are tested for impairment by comparing the unit’s fair value to its carrying value. The fair value of each reporting unit was estimated using a discounted cash flow model combined with market valuation approaches. Significant estimates and assumptions are used in assessing the fair value of reporting units. These estimates and assumptions involved future cash flows, growth rates, discount rates, weighted average cost of capital and estimates of market valuations for each of the reporting units.

The Company recorded goodwill impairment charges of $2.7 million, $0.6 million and $33.9 million in operating results during the fourth quarters of 2003, 2004 and 2005, respectively. The Company recorded an additional impairment charge of $2.7 million in 2004 related to operations that were subsequently discontinued in 2005. This impairment charge is reflected in the operating income (loss) associated with discontinued operations. The impairment charges during 2003 primarily resulted from changes in operating plans that were identified in the fourth quarter of 2003 for certain of the Company’s reporting units as part of our annual budgeting and business planning process. The impairment charge during 2004 and 2005 resulted from the Company’s estimation that the operating environment, conditions and performance of certain of our entities could no longer support the goodwill balances associated with them.

The changes in the carrying amount of goodwill for the years ended December 31, 2003, 2004 and 2005 are as follows (in thousands):

Goodwill balance as of December 31, 2003(a)	$	104,034
Goodwill related to sale of operation	(564		)
Impairment adjustment	(3,347		)
Goodwill balance as of December 31, 2004(a)	$	100,123
Goodwill related to sales of operations	(3,292		)
Impairment adjustment	(33,877		)
Goodwill balance as of December 31, 2005	$	62,954

(a) A portion of this goodwill balance is included in “Assets Related to Discontinued Operations” in the Company’s consolidated balance sheet.

6. Restructuring Charges

During the first three quarters of 2003, the Company recorded restructuring charges of approximately $3.2 million pre-tax. These charges included approximately $1.5 million for severance costs and retention bonuses primarily associated with the curtailment of the Company’s energy efficiency marketing activities, a reorganization of the Company’s national accounts operations as well as a reduction in corporate personnel. The severance costs and retention bonuses related to the termination of 88 employees, all of whom had left the Company by December 31, 2003. The restructuring charges for this period also included approximately $1.6 million for remaining lease obligations and $0.1 million of other costs recorded in connection with the actions described above. The Company increased its accrual for these remaining lease obligations by $0.6 million in 2004 and $0.3 million in 2005 based on revised estimates of when and to what extent it believes it can sublease the related facilities. These increases to the accrual were included in “Cost of Services” and in “Selling, General and Administrative Expenses” in the Company’s consolidated statement of operations.

Accrued lease termination costs remaining from past restructuring charges are expected to be completed by 2009.

The following table shows the remaining liabilities associated with the cash portion of the restructuring charges as of December 31, 2003, 2004 and 2005 (in thousands):

Credit Facility

On June 30, 2005, the Company entered into a senior credit facility (the “Facility”) provided by a syndicate of banks. The Facility consists of a $75.0 million revolving credit facility which is available for borrowings and letters of credit. The facility will expire on June 30, 2009. As of December 31, 2005, the total of the Facility was $75.0 million, with no outstanding borrowings, $22.1 million in letters of credit outstanding, and $52.9 million of credit available.

Certain of the Company’s vendors require letters of credit to ensure reimbursement for amounts they are disbursing on the Company’s behalf, such as to beneficiaries under the Company’s self-funded insurance programs. The Company has also occasionally used letters of credit to guarantee performance under its contracts and to ensure payment to its subcontractors and vendors under those contracts. The Company’s lenders issue such letters of credit through the Facility. A letter of credit commits the lenders to pay specified amounts to the holder of the letter of credit if the holder demonstrates that the Company has failed to perform specified actions. If this were to occur, the Company would be required to reimburse the lenders for amounts they fund to honor the letter of credit holder’s claim. Absent a claim, there is no payment or reserving of funds by the Company in connection with a letter of credit. However, because a claim on a letter of credit would require immediate reimbursement by the Company to its lenders, letters of credit are treated as a use of Facility capacity just the same as actual borrowings. The Company has never had a claim made against a letter of credit that resulted in payments by a lender or by the Company and believes such claim is unlikely in the foreseeable future.

The Company’s borrowing and letter of credit capacity under the Revolving Loan portion of the Facility at any given time is $75.0 million less borrowings and letters of credit outstanding, subject to a borrowing base. The borrowing base is defined under the Facility as 65% of the following: total trade receivables including costs and estimated earnings in excess of billings, less allowances for doubtful accounts, less receivables related to projects that are subject to payment or performance bonds. The borrowing base as of December 31, 2005 was $96.2 million. This borrowing base is substantially greater than the current $75.0 million face-value limit of the Facility. The Company does not expect that this borrowing base provision will limit credit available under the Facility in the foreseeable future.

	As of December 31, 2005
	(in thousands)
Amounts Outstanding:
Revolving loan		$	—
Other non-Facility debt		—
Total debt		$	—
Letters of credit		$	22,139
Available Capacity:
Unused Revolving Loan and letter of credit capacity based on Revolving Loan face value of $75 million		$	52,861
Unused Revolving Loan and letter of credit capacity based on quarter-end debt-to-Credit Facility Adjusted EBITDA covenant		$	52,861

The Company may terminate the Facility in full at any time, however, a termination of the Facility prior to June 30, 2006 would require payment of a fee of $500,000. From June 30, 2006 and until June 30, 2007, the Company may partially reduce the Facility provided such reduction does not exceed $5 million. From July 1, 2007 through June 30, 2008, the Company may partially reduce the Facility provided such reduction does not exceed $10 million, less any prior reductions.

Collateral

The Facility is secured by first liens on substantially all the assets of the Company except for assets related to projects subject to surety bonds. The Facility is secured by a second lien on these assets, which are discussed further below. The Company’s assets are primarily held by its subsidiaries. Accordingly, the Facility is also secured by the capital stock of current and future subsidiaries, and these entities guarantee repayment of amounts due under the Facility.

A common practice in the Company’s industry is the posting of payment and performance bonds with customers. These bonds are offered by financial institutions known as sureties, and provide assurance to the customer that in the event the Company encounters significant financial or operational difficulties, the surety will arrange for the completion of the Company’s contractual obligations and for the payment of the Company’s vendors on the projects subject to the bonds. In cooperation with its lenders, the Company has granted its surety a first lien on assets such as receivables, costs and estimated earnings in excess of billings, and equipment specifically identifiable to projects for which bonds are outstanding, as collateral for potential obligations under bonds. As of December 31, 2005, the amount of these assets was approximately $72.0 million.

Interest Rates and Fees

The Company has a choice of two interest rate options for borrowings under the Facility. Under one option termed the Base Rate Option, the interest rate is determined based on the higher of the Federal Funds Rate plus 0.5% or the prime lending rate offered by Citibank, N.A. (not one of the banks providing the Facility to the Company). Additional margins are then added to the higher of these two rates. These additional margins are determined based on the ratio of the Company’s total debt outstanding as of a given quarterend to its earnings before interest, taxes, depreciation and amortization (“Credit Facility Adjusted EBITDA”) for the twelve months ending as of that quarterend, as shown below. Credit Facility Adjusted EBITDA as defined under the Facility is discussed in more detail below under “Covenants and Restrictions.”

Under the other interest rate option termed the Eurodollar Rate Option, borrowings bear interest based on designated one to six-month Eurodollar rates that correspond very closely to rates described in various general business media sources as the London Interbank Offered Rate or “LIBOR.” Additional margins are then added to LIBOR for borrowings based on the Company’s ratio of debt to Credit Facility Adjusted EBITDA, as shown below.

Letter of credit fees under the Facility are also based on the Company’s ratio of debt to Credit Facility Adjusted EBITDA, as shown below.

The interest rates underlying the Base Rate and Eurodollar Rate Options under the Facility are floating rates determined by the broad financial markets, meaning they can and do move up and down from time to time. For illustrative purposes, the following are the respective market rates as of December 31, 2005 relating to interest options under the Facility:

Base Rate Option—The higher of:
Federal Funds Rate plus 0.50%	4.75	%
Citibank, N.A. Prime Rate	7.25	%
Eurodollar Rate Option:
One-month LIBOR	4.39	%
Six-month LIBOR	4.70	%

	Debt to Credit Facility Adjusted EBITDA
	Less than 0.75			0.75 to 1.25			1.25 or greater
Additional Per Annum Interest Margin Added Under:
Base Rate Option		1.00	%		1.50	%		2.00	%
Eurodollar Rate Option		2.00	%		2.50	%		3.00	%
Per Annum Letter of Credit Fees (not added to underlying Base Rate or Eurodollar Rate)		1.50	%		1.875	%		2.25	%

Commitment fees of 0.25% per annum are payable on the portion of Revolving Loan capacity not in use for borrowings or letters of credit at any given time.

The Company incurred approximately $0.4 million in financing and professional costs in connection with the arrangement of the Facility. These costs are amortized as a non-cash charge to interest expense over the term of the Facility in an amount of approximately $0.1 million per year. If the size of the Facility is reduced, the Company may have to accelerate amortization of these deferred financing and professional costs. Excluding the amortization of debt financing and arrangement costs, the Company estimates that the interest rate applicable to borrowings under the Facility would be approximately 6.39% as of December 31, 2005.

Covenants and Restrictions

Net loss	$	(6,226	)
Income taxes—continuing operations and discontinued operations	21,133
Interest expense, net	309
Write off of debt costs	870
Depreciation and amortization expense	4,818
Goodwill impairment—continuing operations and discontinued operations	33,877
Credit Facility Adjusted EBITDA	$	54,781

The Facility’s principal financial covenants include:

Fixed Charge Coverage Ratio—The Facility requires that the ratio of Credit Facility Adjusted EBITDA, less non-financed capital expenditures, tax provision, dividends and amounts used to repurchase stock to the sum of interest expense and scheduled principal payments be at least 1.50. Capital expenditures, tax provision, dividends and stock repurchase payments are defined under the Facility for purposes of this covenant to be amounts for the four quarters ending as of any given quarterly covenant compliance measurement date. Interest expense is defined under the Facility as interest expense for the four quarters ending as of any given quarterly covenant compliance measurement date, excluding corresponding twelve-month amounts for (a) amortization of deferred debt arrangement costs; and (b) mark-to-market interest expense. Scheduled principal payments for this ratio are also measured for the twelve months ending as of any given quarterly covenant compliance measurement date. The Company’s fixed charge coverage ratio as of December 31, 2005 as measured under this covenant was 35.84 as compared to a minimum covenant requirement of 1.50.

Tangible Net Worth—The Facility requires that the Company’s tangible net worth not be less than the sum of (a) $100.5 million; (b) 50% of net income earned beginning April 1, 2005; and (c) the net proceeds of any equity transactions. For purposes of this ratio, the Facility defines tangible net worth as stockholders’ equity less the book value of the following intangible assets: goodwill, patents, copyrights, licenses, franchises, trade names, trade secrets, and operating leases. The Facility also provides that for purposes of this ratio, net income (loss) excludes any goodwill impairment charges. The Company’s tangible net worth as of December 31, 2005 as measured under this covenant was $150.6 million, as compared to a covenant minimum of $116.9 million.

Debt to Credit Facility Adjusted EBITDA—The Facility requires that the Company’s ratio of debt to Credit Facility Adjusted EBITDA not exceed 2.5. The Company’s debt-to-Credit Facility Adjusted EBITDA ratio as of December 31, 2005 as measured under this covenant was zero because the Company has no debt.

Capital Expenditures—The Facility limits capital expenditures to $20.0 million per year. The Company’s capital expenditures during the year ended December 31, 2005 were $6.2 million.

Other Restrictions—The Facility limits payment of dividends and repurchase of shares by the Company to a combined maximum of $20.0 million per year, and otherwise limits non-Facility debt,

capital lease obligations, acquisitions, investments, and sales of assets. During the fourth quarter of 2005, the Company amended the Facility to permit the sale of substantially all of the assets of two subsidiaries. That sale is discussed in Note 4 “Discontinued Operations.” The amendment also provides additional flexibility for the Company to purchase its common shares.

Interest Expense and Related Charges in Connection with Previous Credit Facilities

The credit facility that preceded the Company’s current one was in place from December 2003 to June 2005. The Company’s next previous credit facility had been in place from October 2002 to December 2003. Interest expense for 2003, 2004 and 2005 included the following primary elements (in thousands):

	2003		2004		2005
Interest expense on borrowings, and unused commitment fees	$	1,397	$	704	$	391
Letter of credit fees	512		443		389
Amortization of deferred debt arrangement costs and discount	1,496		419		295
Mark-to-market adjustments on derivatives	488		—		—
Total	$	3,893	$	1,566	$	1,075

When the Company’s previous credit facilities were reduced in size or terminated, corresponding amounts of deferred debt arrangement costs were written off. The largest of these write-offs occurred in the fourth quarter of 2003 when the Company terminated the preceding facility, which had been in place just over one year. This write-off was partially offset by a $1.3 million gain associated with the reduction in the value of a stock warrant and related put obligation that arose when the facility terminated in the fourth quarter was originally established. This reduction in the value of the warrant and put obligation resulted from a significant restriction in the holder’s ability to exercise the put provision. This restriction was agreed to by the holder in connection with terminating the related credit facility. These charges are reported as “Write-off of debt costs and discount, net” in the Company’s consolidated statement of operations, and include the following primary elements (in thousands):

	2003			2004			2005
Write-off of deferred financing fees and transaction costs	$	3,246			$	—	$	870
Write-off of discount originally arising from issue of stock warrant and related put to credit facility lender	2,250				—		—
Reduction in valuation of warrant and put obligation	(1,324		)		—		—
Total	$	4,172			$	—	$	870

The warrant was exercised in the fourth quarter of 2004. As a result of the exercise, the related put rights associated with the warrant terminated.

Significant components of the net deferred tax assets and net deferred tax liabilities as reflected on the balance sheet are as follows:

	December 31,
	2004			2005
	(In thousands)
Deferred income tax assets—
Accounts receivable and allowance for doubtful accounts	$	2,209		$	1,423

The deferred income tax assets and liabilities reflected above are included in the consolidated balance sheets as follows (in thousands):

	December 31,
	2004		2005
Deferred income tax assets—
Prepaid expenses and other	$	10,604	$	8,747
Other non-current assets	7,523		6,090
Total deferred income tax assets	$	18,127	$	14,837

As of December 31, 2005 the Company had future tax benefits of $3.9 million related to $60 million of available state net operating loss carryforwards for income tax purposes which expire in 2006 through 2025. Valuation allowances of $1.9 million and $0.1 million, respectively, have been recorded against net operating loss carryforwards and related net state deferred tax assets. Future tax benefits for state net operating losses decreased by $0.7 million, primarily through utilization. The Company recorded an increase in valuation allowances of $0.1 million for the year ending December 31, 2005. A deferred tax asset for state net operating loss carryforwards, net of related valuation allowance, of $0.6 million reflects the Company’s conclusion that is likely that this asset will be realized based upon expected future earnings in certain subsidiaries. The Company updates this assessment of the realizability of deferred tax assets relating to state net operating loss carry-forwards quarterly.

Federal, state and local authorities routinely audit income tax returns filed by the Company. During 2005, the Company concluded an Internal Revenue Service (IRS) examination of its 2003 federal income tax return. No change was made to the Company’s tax return. It is the Company’s policy to establish reserves for taxes that may become payable in future years as a result of tax examinations. The Company establishes reserves for taxes based on management’s assessment of the probability that examinations will result in additional income tax payments. Tax reserves are analyzed quarterly and adjustments are recorded, as events occur to warrant adjustment to reserves. The Company has recorded $0.9 million in income tax reserves as of December 31, 2005. For the years ended December 31, 2004 and 2005 the Company has recorded decreases of $0.04 million and $0.2 million to tax reserves respectively.

During 2005, the Company analyzed certain provisions of the American Jobs Creation Act of 2004 (the Act) as that Act relates to potentially favorable treatment for repatriation of non-U.S. earnings and determined that no non-U.S. earnings should be repatriated solely for purposes of obtaining tax benefits afforded by the Act. For calendar year 2005, the Company recorded tax benefits of approximately $0.2 million in connection with deductions that apply to certain of the Company’s qualified production activities as permitted by the American Jobs Creation Act of 2004.

11. Employee Benefit Plans

The Company and certain of the Company’s subsidiaries sponsor various retirement plans for most full-time and some part-time employees. These plans consist of defined contribution plans and multi-employer pension plans and cover employees at substantially all of the Company’s operating locations. The defined contribution plans generally provide for contributions up to 2.5% of covered employees’ salaries or wages. These contributions totaled $2.5 million for 2003, $2.6 million for 2004 and $3.1 million for 2005. Of these amounts, approximately $0.1 million and $0.3 million were payable to the plans at December 31, 2004 and 2005, respectively.

Certain of the Company’s subsidiaries also participate in various multi-employer pension plans for the benefit of employees who are union members. As of December 31, 2005, the Company had 83 employees who were union members. Company contributions to these plans were approximately $0.5 million for 2003, $0.9 million for 2004 and $0.4 million for 2005. The data available from administrators of the multi-employer pension plans is not sufficient to determine the accumulated benefit obligations, nor the net assets attributable to the multi-employer plans in which Company employees participate.

12. Commitments and Contingencies

Leases

The Company leases certain facilities and equipment under noncancelable operating leases. Rent expense for the years ended December 31, 2003, 2004 and 2005 was $14.9 million, $14.5 million, and $14.9 million, respectively. The Company recognizes escalating rental payments that are quantifiable at the inception of the lease on a straight-line basis over the lease term. Concurrent with the acquisitions of certain acquired companies, the Company entered into various agreements with previous owners to lease land and buildings used in the Company’s operations. The terms of these leases generally range from three to ten years and certain leases provide for escalations in the rental expenses each year, the majority of which are based on inflation. Included in the 2003, 2004 and 2005 rent expense above are approximately $3.6 million, $2.8 million and $2.5 million of rent paid to these related parties, respectively. The following represents future minimum rental payments under noncancelable operating leases (in thousands):

Year ending December 31—
2006	$	8,357
2007	7,311
2008	5,610
2009	4,199
2010	1,655
Thereafter	5,201
	$	32,333

Claims and Lawsuits

The Company is subject to certain claims and lawsuits arising in the normal course of business. The Company maintains various insurance coverages to minimize financial risk associated with these claims.

The Company has estimated and provided accruals for probable losses and related legal fees associated with certain of its litigation in the accompanying consolidated financial statements. While the Company cannot predict the outcome of these proceedings, in management’s opinion and based on reports of counsel, any liability arising from these matters individually and in the aggregate will not have a material effect on the Company’s operating results or financial condition, after giving effect to provisions already recorded.

In addition to the matters described above, the Company is defending a dispute arising out of an alleged delay related to a multi-family construction project. If the Company is not successful in this dispute, it could have a material adverse effect on the Company’s operating results. However, management believes the likelihood of an adverse result of this magnitude is remote, and management believes the accruals relating to the matter appropriately reflect a probable outcome.

Surety

Many customers, particularly in connection with new construction, require the Company to post performance and payment bonds issued by a financial institution known as a surety. If the Company fails to perform under the terms of a contract or to pay subcontractors and vendors who provided goods or services under a contract, the customer may demand that the surety make payments or provide services under the bond. The Company must reimburse the surety for any expenses or outlays it incurs. To date, the Company is not aware of any losses to its sureties in connection with bonds the sureties have posted on the Company’s behalf, and does not expect such losses to be incurred in the foreseeable future.

Surety market conditions are currently challenging as a result of significant losses incurred by many sureties in recent periods, both in the construction industry as well as in certain larger corporate bankruptcies. As a result, less bonding capacity is available in the market and terms have become more restrictive. Further, under standard terms in the surety market, sureties issue bonds on a project-by-project basis, and can decline to issue bonds at any time. Historically, approximately 30% of the Company’s business has required bonds. While the Company has enjoyed a longstanding relationship with its primary surety and has added another surety to further support its bonding needs, current market conditions as well as changes in the sureties’ assessment of the Company’s operating and financial risk could cause the sureties to decline to issue bonds for the Company’s work. If that were to occur, the alternatives include doing more business that does not require bonds, posting other forms of collateral for project performance such as letters of credit or cash, and seeking bonding capacity from other sureties. The Company would likely also encounter concerns from customers, suppliers and other market participants as to its creditworthiness. While the Company believes its general operating and financial characteristics, including a significant amount of cash on its balance sheet, would enable it to ultimately respond effectively to an interruption in the availability of bonding capacity, such an interruption would likely cause the Company’s revenues and profits to decline in the near term.

Self-Insurance

The Company’s self-insurance arrangements currently are as follows:

Worker’s Compensation—The per-incident deductible for worker’s compensation is $500,000. Losses above that amount are determined by statutory rules on a state-by-state basis, and are fully covered by excess worker’s compensation insurance.

General and Employer’s Liability—For general liability and employer’s liability, the Company self-insures the first $500,000 of each loss, is fully insured for the next $500,000 of each loss, then has a single, aggregate excess loss insurance policy that covers losses up to $50 million across both these risk areas (as well as auto liability noted below).

Auto Liability—For auto liability, the Company self-insures the first $500,000 of each loss, is fully insured for the next $1.5 million of each loss, then has a single, aggregate excess loss insurance policy that covers losses up to $50 million.

Employee Medical—The Company’s per-incident deductible for employee group health claims is $300,000. Insurance then covers any Company responsibility for medical claims in excess of the deductible amount.

It is important to note that the Company’s $50 million of aggregate excess loss coverage above applicable per-incident deductibles represents one policy limit that applies to all lines of risk. In other words, the Company does not have a separate $50 million of excess loss coverage for each of general liability, employer’s liability and auto liability.

13. Stockholders’ Equity

Restricted Stock Grants

The Company awarded 82,500 shares of restricted stock to nine members of management on January 21, 2005 under its 2000 Equity Incentive Plan. The shares are subject to full forfeiture if the Company does not meet certain performance levels for the twelve-month period ending March 31, 2006. The grants are also subject to forfeiture if a grantee leaves voluntarily or is terminated for cause. The latter forfeiture provisions lapse pro rata over four-year periods that started on the date of the respective grants. Due to the departure of an individual, 12,500 shares of restricted stock were forfeited in the second quarter of 2005.

The Company awarded 225,000 shares of restricted stock to five members of senior management on June 8, 2004 under its 2000 Equity Incentive Plan. The shares were subject to forfeiture if the Company had not achieved certain performance levels for the twelve-month period ending June 30, 2005. These performance levels were met by the Company. The shares are subject to forfeiture if a grantee leaves voluntarily or is terminated for cause. Such forfeiture provisions lapse pro rata over three-year or four-year periods that started on the date of the respective grants. Due to the departure of an individual, 50,000 shares of restricted stock were forfeited during the second quarter of 2005.

The Company awarded 200,000 shares of restricted stock to its Chief Executive Officer on March 22, 2002 under its 2000 Equity Incentive Plan. The shares were subject to forfeiture if the Company had not achieved certain performance levels for the twelve-month period ending March 31, 2003. These performance levels were met by the Company. The shares are subject to forfeiture if the executive leaves voluntarily or is terminated for cause. Such forfeiture provisions lapse pro rata over a four-year period that started on the date of grant.

Compensation expense relating to the grants is charged to earnings over the respective three-year or four-year periods during which their forfeiture provisions lapse. The initial value of each award was established based on the market price on the date of grant, and was reflected as a reduction of stockholders’ equity for unearned compensation at that time. This value, and the related compensation

expense, is adjusted up or down based on the market price of the Company’s stock during the first year following each respective grant while the performance conditions are in effect. Once the performance conditions are met, the value of the award is fixed based on the market price of the Company’s stock at that time, and is charged to earnings over the remaining two-year or three-year period during which remaining forfeiture provisions lapse.

Warrant

In connection with a previous credit facility, the Company granted a lender a warrant to purchase 409,051 shares of Company common stock (“Common Stock”) for nominal consideration. The warrant was exercised in October 2004 in a cashless transaction, whereby the Company issued 408,144 shares upon exercise of the warrant.

When the warrant was originally issued, it carried additional rights involving increases in, registration of, and sale of shares related to the warrant. The warrant holder also had the right to “put,” or require the Company to repurchase, some or all of the shares related to the warrant in certain circumstances. Some of these rights were waived in December 2003 when the credit facility in connection with which the warrant was originally issued was terminated.

The value of the warrant and put when originally issued of $2.9 million was reflected as a discount of the Company’s obligations under the previous credit facility, and as an obligation in long-term liabilities. When this credit facility was terminated in December 2003, the discount reflected against debt under the credit facility was written off and included in “Write-off of debt costs and discount, net” in the Company’s consolidated statement of operations. Also upon the termination of the credit facility, the warrant holder waived certain of the additional rights under the warrant and put. In connection with this waiver, the Company recognized a $1.3 million gain in December 2003 associated with the reduction in the value of the warrant and put obligation. This gain was also included in the “Write-off of debt costs and discount, net” caption.

As noted above, the warrant was exercised in a cashless transaction in October 2004. As a result of the exercise, all additional rights under the warrant described above have terminated. Also as a result of the exercise, the remaining value of the warrant was eliminated as an obligation and added to stockholders’ equity in October 2004.

While the warrant and put were outstanding, their value changed over time, principally in response to changes in the market price of the Common Stock. The warrant and the put qualified as a derivative for financial reporting purposes. Accordingly, such changes in the value of the warrant and put in any given period were included in the Company’s statement of operations for that period and in the Company’s long-term liabilities, even though the warrant and put had not been terminated and settled in cash during the period. Such adjustments are known as mark-to-market adjustments. During the year ended December 31, 2003, this adjustment was a loss of $0.5 million and was included in interest expense because the warrant and put related to the Company’s then-existing credit facility. Because the warrant and put did not relate to the Company’s current credit facility, mark-to-market adjustments during the year ended December 31, 2004, which were losses of $0.4 million, are reflected as other income (expense) in the Company’s statement of operations. There are no further mark-to-market adjustments to income associated since the warrant and put are no longer outstanding.

Restricted Common Stock

In March 1997, Notre Capital Ventures II, L.L.C. (“Notre”) exchanged 2,742,912 shares of Common Stock for an equal number of shares of restricted voting common stock (“Restricted Voting Common Stock”). The holders of Restricted Voting Common Stock are entitled to elect one member of the Company’s Board of Directors and to 0.55 of one vote for each share on all other matters on which they

are entitled to vote. Holders of Restricted Voting Common Stock are not entitled to vote on the election of any other directors.

Each share of Restricted Voting Common Stock will automatically convert to Common Stock on a share-for-share basis (i) in the event of a disposition of such share of Restricted Voting Common Stock by the holder thereof (other than a distribution which is a distribution by a holder to its partners or beneficial owners, or a transfer to a related party of such holders (as defined in Sections 267, 707, 318 and/or 4946 of the Internal Revenue Code of 1986, as amended)), (ii) in the event any person acquires beneficial ownership of 15% or more of the total number of outstanding shares of Common Stock, or (iii) in the event any person offers to acquire 15% or more of the total number of outstanding shares of Common Stock. After July 1, 1998, the Board of Directors may elect to convert any remaining shares of Restricted Voting Common Stock into shares of Common Stock in the event 80% or more of the originally outstanding shares of Restricted Voting Common Stock are converted into shares of Common Stock. As of December 31, 2005, there were 995,975 shares of Restricted Voting Common Stock remaining.

Earnings Per Share

Basic earnings per share (“EPS”) is computed by dividing net income by the weighted average number of shares of common stock outstanding during the year. Diluted EPS is computed considering the dilutive effect of stock options, warrants and contingently issuable restricted stock.

Under EPS calculation methods established by generally accepted accounting principles, including the effect of options whose exercise price exceeds the average market price of the Common Stock for a given period would increase calculated EPS. This impact is called “anti-dilutive.” Generally accepted accounting principles for determining EPS require that any options or other common stock equivalents whose inclusion in determining EPS would have an anti-dilutive effect be excluded. Accordingly, options to purchase 1.3 million shares of Common Stock at prices ranging from $7.00 to $21.438 per share which were outstanding for the year ended December 31, 2004, were not included in the computation of diluted EPS because they were anti-dilutive.

Including options in an EPS calculation for a period in which a loss is reported is also anti-dilutive. Accordingly, because the Company reported a loss from continuing operations for the years ended December 31, 2003 and 2005, options outstanding for the year ended December 31, 2003, to purchase 5.6 million shares of Common Stock at prices ranging from $1.90 to $21.438 per share were not included in the computation of diluted EPS because they were anti-dilutive. Options to purchase 0.9 million shares of common stock at prices ranging from $1.90 to $21.438 per share were outstanding at December 31, 2005 and were excluded from the computation of diluted EPS because they were anti-dilutive.

The following table summarizes information regarding the Company’s outstanding stock options as of December 31, 2003, 2004 and 2005:

	Number of Options Outstanding
Exercise Price	December 31, 2003		December 31, 2004		December 31, 2005

As noted above in Note 13, “Stockholders’ Equity,” the Company issued a warrant to purchase 409,051 shares of Common Stock along with related put rights for nominal consideration. The dilutive impact of this warrant was computed assuming the issuance of shares equal to the value of the warrant obligation at the end of any given period while it was outstanding, and excluding the income effect for the period of any mark-to-market adjustments made in connection with valuing the warrant. This impact was dilutive for the year ended December 31, 2003. As this impact was anti-dilutive for the year ended December 31, 2004, the effect of the warrant was excluded from earnings per share amounts for that year. As a result of the warrant’s exercise in October 2004, its related shares have now become part of the Company’s outstanding Common Stock.

The following tables reconcile the income (loss) from continuing operations and the net income (loss) on the statement of operations with the corresponding earnings (losses) that are used in computing basic and diluted earnings per share for each of the periods presented (in thousands):

14. Stock Option Plans

Long-Term Incentive Plans

In March 1997, the Company’s stockholders approved the Company’s 1997 Long-Term Incentive Plan (the “1997 Plan”) which provides for the granting of incentive or non-qualified stock options, stock appreciation rights, restricted or deferred stock, dividend equivalents or other incentive awards to directors, employees and consultants to the Company. Aggregate options granted under the 1997 Plan may not exceed 13% of the total number of shares of Common Stock outstanding at the time of any grant under

the plan. The options the Company has granted under the 1997 Plan have exercise prices that were equal to the fair market value of the Common Stock on the date of grant, and which become exercisable in five equal annual installments beginning on the first anniversary of the date of grant. The options expire after seven years from the date of grant if unexercised. Outstanding options may be canceled and reissued under terms specified in the plan. The number of shares available under this plan varies with the total number of shares of Common Stock outstanding. As of December 31, 2005, there were 4.0 million shares available for issuance under this plan. The 1997 Plan will expire in March 2007.

In May 2000, the Company’s stockholders approved the Company’s 2000 Incentive Plan (the “2000 Plan”) which provides for the granting of incentive or non-qualified stock options, restricted stock or performance awards to directors, employees and other persons or entities as approved by the Board of Directors. The options the Company has granted under the 2000 Plan have exercise prices that were equal to the fair market value of the Common Stock on the date of grant, and which become exercisable in four equal annual installments beginning on the first anniversary of the date of grant. The options expire after ten years from the date of grant if unexercised. Under the 2000 Plan, 3.5 million shares were authorized for issuance, of which none remain available for issuance as of December 31, 2005.

Non-Employee Directors’ Stock Plan

In March 1997, the Company’s stockholders approved the 1997 Non-Employee Directors’ Stock Plan (the “Directors’ Plan”), which provides for the granting of stock options or stock appreciation rights to non-employees. The number of shares authorized and reserved for issuance under the Directors’ Plan is 500,000 shares. The Directors’ Plan provided for the automatic grant of options to purchase 10,000 shares to each non-employee director serving at the commencement of the initial public offering of the Company.

Under the Directors’ Plan, each non-employee director is granted options to purchase 10,000 shares at the time of the director’s initial election. In addition, each non-employee director is automatically granted options to purchase an additional 10,000 shares at each annual meeting of the stockholders that is more than two months after the date of the director’s initial election. All options are granted with an exercise price equal to the fair market value at the date of grant and are immediately vested upon grant.

Either at the time of the initial public offering or upon election as a director, options were granted to six members of the Board of Directors to purchase in each case 10,000 shares of Common Stock at the initial public offering price or at the price in effect at the time of their election. Each of these directors received options for shares on the dates of the annual meetings which they have attended. In addition, directors who cease to be employees become eligible for the annual grant. These options will expire at the earlier of ten years from the date of grant or one year after termination of service as a director. As of December 31, 2005, 0.2 million options were outstanding related to this plan.

The Directors’ Plan allows non-employee directors to receive shares (“Deferred Shares”) at future settlement dates in lieu of cash. The number of Deferred Shares will have an aggregate fair market value equal to the fees payable to the directors. No Deferred Shares have been issued as of December 31, 2005.

The Company has never altered the price of any option after its grant.

The Company’s quarterly results of operations and the related earnings per share amounts have been restated to reflect the effects of discontinued operations.

(a) Fourth quarter 2004 includes a goodwill impairment charge of $0.6 million.

(b) Fourth quarter 2005 includes a goodwill impairment charge of $33.9 million.

The sums of the individual quarterly earnings per share amounts do not necessarily agree with year-to-date earnings per share as each quarter’s computation is based on the weighted average number of shares outstanding during the quarter, the weighted average stock price during the quarter and the dilutive effects of options, warrants, and contingently issuable restricted stock in each quarter.
