Notes to Consolidated Financial Statements (Unaudited)

NOTE 1 Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with instructions to the Quarterly Report on Form 10-Q and Rule 10-01 of Regulation S-X. Consequently, certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted. References to the “Company,” “EMCOR,” “we,” “us,” “our” and similar words refer to EMCOR Group, Inc. and its consolidated subsidiaries unless the context indicates otherwise. Readers of this report should refer to the consolidated financial statements and the notes thereto included in our latest Annual Report on Form 10-K filed with the Securities and Exchange Commission.

In our opinion, the accompanying unaudited consolidated financial statements contain all adjustments (consisting only of those of a normal recurring nature) necessary to present fairly our financial position and the results of our operations. Our reportable segments reflect certain reclassifications of prior year amounts from our United States mechanical construction and facilities services segment to our United States industrial services segment due to changes in our internal reporting structure.

The results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of the results to be expected for the year ending December 31, 2019.

NOTE 2 New Accounting Pronouncements

On January 1, 2019, we adopted the accounting pronouncement issued by the Financial Accounting Standards Board (“FASB”) to replace existing lease accounting guidance. This pronouncement is intended to provide enhanced transparency and comparability by requiring lessees to record right-of-use assets and corresponding lease liabilities on the balance sheet for most leases. Expenses associated with leases continue to be recognized in a manner similar to previous accounting guidance. We adopted this pronouncement utilizing the transition practical expedient added by the FASB, which eliminated the requirement that entities apply the new lease standard to the comparative periods presented in the year of adoption. The adoption of this accounting pronouncement resulted in the recognition of operating lease right-of-use assets and associated lease liabilities on our balance sheet of $220.2 million and $227.1 million, respectively, as of January 1, 2019. Additional required disclosures have been included within Note 14 - Leases of the notes to consolidated financial statements. Such adoption did not have an impact on our liquidity, results of operations or our compliance with the various covenants contained within our 2016 Credit Agreement as described in further detail within Note 8 - Debt of the notes to consolidated financial statements.

On January 1, 2019, we adopted the accounting pronouncement issued by the FASB related to the reporting of certain items in accumulated other comprehensive income (loss) (“AOCI”). This guidance provides entities the option to reclassify to retained earnings certain tax effects stranded in AOCI as a result of tax reform. As part of our adoption of this accounting pronouncement, we elected not to reclassify the stranded tax effects related to the retirement plans of our United States subsidiaries as such amounts are immaterial. Tax effects remaining in AOCI will be released upon liquidation of each individual retirement plan.

In June 2016, an accounting pronouncement was issued by the FASB which changes the way in which entities estimate and present credit losses for most financial assets, including accounts receivable. This pronouncement is effective for annual and interim periods beginning after December 15, 2019, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this accounting pronouncement will have on its financial position and/or results of operations.

NOTE 3 Revenue from Contracts with Customers

The Company recognizes revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services by applying the following five step model:

(1) Identify the contract with a customer

A contract with a customer exists when: (a) the parties have approved the contract and are committed to perform their respective obligations, (b) the rights of the parties can be identified, (c) payment terms can be identified, (d) the arrangement has commercial substance, and (e) collectibility of consideration is probable. Judgment is required when determining if the contractual criteria are met, specifically in the earlier stages of a project when a formally executed contract may not yet exist. In these situations, the Company evaluates all relevant facts and circumstances, including the existence of other forms of documentation or historical experience with our customers that may indicate a contractual agreement is in place and revenue should be recognized. In determining if the collectibility of consideration is probable, the Company considers the customer’s ability and intention to pay

Notes to Consolidated Financial Statements (Unaudited)

NOTE 3 Revenue from Contracts with Customers - (Continued)

such consideration through an evaluation of several factors, including an assessment of the creditworthiness of the customer and our prior collection history with such customer.

(2) Identify the performance obligations in the contract

At contract inception, the Company assesses the goods or services promised in a contract and identifies, as a separate performance obligation, each distinct promise to transfer goods or services to the customer. The identified performance obligations represent the “unit of account” for purposes of determining revenue recognition. In order to properly identify separate performance obligations, the Company applies judgment in determining whether each good or service provided is: (a) capable of being distinct, whereby the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer, and (b) distinct within the context of the contract, whereby the transfer of the good or service to the customer is separately identifiable from other promises in the contract.

In addition, when assessing performance obligations within a contract, the Company considers the warranty provisions included within such contract. To the extent the warranty terms provide the customer with an additional service, other than assurance that the promised good or service complies with agreed upon specifications, such warranty is accounted for as a separate performance obligation. In determining whether a warranty provides an additional service, the Company considers each warranty provision in comparison to warranty terms which are standard in the industry.

Our contracts are often modified through change orders to account for changes in the scope and price of the goods or services we are providing. Although the Company evaluates each change order to determine whether such modification creates a separate performance obligation, the majority of our change orders are for goods or services that are not distinct within the context of our original contract and, therefore, are not treated as separate performance obligations.

(3) Determine the transaction price

The transaction price represents the amount of consideration to which the Company expects to be entitled in exchange for transferring promised goods or services to our customers. The consideration promised within a contract may include fixed amounts, variable amounts, or both. To the extent the performance obligation includes variable consideration, including contract bonuses and penalties that can either increase or decrease the transaction price, the Company estimates the amount of variable consideration to be included in the transaction price utilizing one of two prescribed methods, depending on which method better predicts the amount of consideration to which the entity will be entitled. Such methods include: (a) the expected value method, whereby the amount of variable consideration to be recognized represents the sum of probability weighted amounts in a range of possible consideration amounts, and (b) the most likely amount method, whereby the amount of variable consideration to be recognized represents the single most likely amount in a range of possible consideration amounts. When applying these methods, the Company considers all information that is reasonably available, including historical, current and estimates of future performance. The expected value method is typically utilized in situations where a contract contains a large number of possible outcomes while the most likely amount method is typically utilized in situations where a contract has only two possible outcomes.

Variable consideration is included in the transaction price only to the extent it is probable, in the Company’s judgment, that a significant future reversal in the amount of cumulative revenue recognized under the contract will not occur when the uncertainty associated with the variable consideration is subsequently resolved. This threshold is referred to as the variable consideration constraint. In assessing whether to apply the variable consideration constraint, the Company considers if factors exist that could increase the likelihood or the magnitude of a potential reversal of revenue, including, but not limited to, whether: (a) the amount of consideration is highly susceptible to factors outside of the Company’s influence, such as the actions of third parties, (b) the uncertainty surrounding the amount of consideration is not expected to be resolved for a long period of time, (c) the Company’s experience with similar types of contracts is limited or that experience has limited predictive value, (d) the Company has a practice of either offering a broad range of price concessions or changing the payment terms and conditions of similar contracts in similar circumstances, and (e) the contract has a large number and broad range of possible consideration amounts.

Pending change orders represent one of the most common forms of variable consideration included within contract value and typically represent contract modifications for which a change in scope has been authorized or acknowledged by our customer, but the final adjustment to contract price is yet to be negotiated. In estimating the transaction price for pending change orders, the Company considers all relevant facts, including documented correspondence with the customer regarding acknowledgment of and/or agreement with the modification, as well as historical experience with the customer or similar contractual circumstances.

NOTE 3 Revenue from Contracts with Customers - (Continued)

Based upon this assessment, the Company estimates the transaction price, including whether the variable consideration constraint should be applied.

Contract claims are another form of variable consideration which is common within our industry. Claim amounts represent revenue that has been recognized for contract modifications that are not submitted or are in dispute as to both scope and price. In estimating the transaction price for claims, the Company considers all relevant facts available. However, given the uncertainty surrounding claims, including the potential long-term nature of dispute resolution and the broad range of possible consideration amounts, there is an increased likelihood that any additional contract revenue associated with contract claims is constrained. The resolution of claims involves negotiations and, in certain cases, litigation. In the event litigation costs are incurred by us in connection with claims, such litigation costs are expensed as incurred, although we may seek to recover these costs.

For some transactions, the receipt of consideration does not match the timing of the transfer of goods or services to the customer. For such contracts, the Company evaluates whether this timing difference represents a financing arrangement within the contract. Although rare, if a contract is determined to contain a significant financing component, the Company adjusts the promised amount of consideration for the effects of the time value of money when determining the transaction price of such contract. Although our customers may retain a portion of the contract price until completion of the project and final contract settlement, these retainage amounts are not considered a significant financing component as the intent of the withheld amounts is to provide the customer with assurance that we will complete our obligations under the contract rather than to provide financing to the customer. In addition, although we may be entitled to advanced payments from our customers on certain contracts, these advanced payments generally do not represent a significant financing component as the payments are used to meet working capital demands that can be higher in the early stages of a contract, as well as to protect us from our customer failing to meet its obligations under the contract.

Changes in the estimates of transaction prices are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made. Such changes in estimates can result in the recognition of revenue in a current period for performance obligations which were satisfied or partially satisfied in prior periods. Such changes in estimates may also result in the reversal of previously recognized revenue if the ultimate outcome differs from the Company’s previous estimate. For the three and six months ended June 30, 2019 and 2018, there were no significant amounts of revenue recognized during the period related to performance obligations satisfied in prior periods. In addition, for the three and six months ended June 30, 2019 and 2018, there were no significant reversals of revenue recognized associated with the revision of transaction prices.

(4) Allocate the transaction price to performance obligations in the contract

For contracts that contain multiple performance obligations, the Company allocates the transaction price to each performance obligation based on a relative standalone selling price. The Company determines the standalone selling price based on the price at which the performance obligation would have been sold separately in similar circumstances to similar customers. If the standalone selling price is not observable, the Company estimates the standalone selling price taking into account all available information such as market conditions and internal pricing guidelines. In certain circumstances, the standalone selling price is determined using an expected profit margin on anticipated costs related to the performance obligation.

(5) Recognize revenue as performance obligations are satisfied

The Company recognizes revenue at the time the related performance obligation is satisfied by transferring a promised good or service to its customers. A good or service is considered to be transferred when the customer obtains control. The Company can transfer control of a good or service and satisfy its performance obligations either over time or at a point in time. The Company transfers control of a good or service over time and, therefore, satisfies a performance obligation and recognizes revenue over time if one of the following three criteria are met: (a) the customer simultaneously receives and consumes the benefits provided by the Company’s performance as we perform, (b) the Company’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced, or (c) the Company’s performance does not create an asset with an alternative use to us, and we have an enforceable right to payment for performance completed to date.

For our performance obligations satisfied over time, we recognize revenue by measuring the progress toward complete satisfaction of that performance obligation. The selection of the method to measure progress towards completion can be either an input method or an output method and requires judgment based on the nature of the goods or services to be provided.

NOTE 3 Revenue from Contracts with Customers - (Continued)

For our construction contracts, revenue is generally recognized over time as our performance creates or enhances an asset that the customer controls as it is created or enhanced. Our fixed price construction projects generally use a cost-to-cost input method to measure our progress towards complete satisfaction of the performance obligation as we believe it best depicts the transfer of control to the customer which occurs as we incur costs on our contracts. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. For our unit price construction contracts, progress towards complete satisfaction is measured through an output method, such as the amount of units produced or delivered, when our performance does not produce significant amounts of work in process or finished goods prior to complete satisfaction of such performance obligations.

For our services contracts, revenue is also generally recognized over time as the customer simultaneously receives and consumes the benefits of our performance as we perform the service. For our fixed price service contracts with specified service periods, revenue is generally recognized on a straight-line basis over such service period when our inputs are expended evenly, and the customer receives and consumes the benefits of our performance throughout the contract term.

The timing of revenue recognition for the manufacturing of new build heat exchangers within our United States industrial services segment depends on the payment terms of the contract, as our performance does not create an asset with an alternative use to us. For those contracts for which we have a right to payment for performance completed to date at all times throughout our performance, inclusive of a cancellation, we recognize revenue over time. For these performance obligations, we use a cost-to-cost input method to measure our progress towards complete satisfaction of the performance obligation as we believe it best depicts the transfer of control to the customer which occurs as we incur costs on our contracts. However, for those contracts for which we do not have a right, at all times, to payment for performance completed to date, we recognize revenue at the point in time when control is transferred to the customer. For bill-and-hold arrangements, revenue is recognized when the customer obtains control of the heat exchanger, which may be prior to shipping, if certain recognition criteria are met.

For certain of our revenue streams, such as call-out repair and service work, outage services, refinery turnarounds and specialty welding services that are performed under time and materials contracts, our progress towards complete satisfaction of such performance obligations is measured using an output method as the customer receives and consumes the benefits of our performance completed to date.

Due to uncertainties inherent in the estimation process, it is possible that estimates of costs to complete a performance obligation will be revised in the near-term. For those performance obligations for which revenue is recognized using a cost-to-cost input method, changes in total estimated costs, and related progress towards complete satisfaction of the performance obligation, are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made. When the current estimate of total costs for a performance obligation indicate a loss, a provision for the entire estimated loss on the unsatisfied performance obligation is made in the period in which the loss becomes evident. For the three and six months ended June 30, 2019 and 2018, there were no changes in total estimated costs that had a significant impact on our operating results. In addition, for the three and six months ended June 30, 2019 and 2018, there were no significant losses recognized.

NOTE 3 Revenue from Contracts with Customers - (Continued)

Contract Assets and Contract Liabilities

Accounts receivable are recognized in the period when our right to consideration is unconditional. Accounts receivable are recognized net of an allowance for doubtful accounts. A considerable amount of judgment is required in assessing the likelihood of realization of receivables.

The timing of revenue recognition may differ from the timing of invoicing to customers. Contract assets include unbilled amounts from our long-term construction projects when revenues recognized under the cost-to-cost measure of progress exceed the amounts invoiced to our customers, as the amounts cannot be billed under the terms of our contracts. Such amounts are recoverable from our customers based upon various measures of performance, including achievement of certain milestones, completion of specified units or completion of a contract. In addition, many of our time and materials arrangements, as well as our contracts to perform turnaround services within the United States industrial services segment, are billed in arrears pursuant to contract terms that are standard within the industry, resulting in contract assets and/or unbilled receivables being recorded, as revenue is recognized in advance of billings. Also included in contract assets are amounts we seek or will seek to collect from customers or others for errors or changes in contract specifications or design, contract change orders or modifications in dispute or unapproved as to scope and/or price, or other customer-related causes of unanticipated additional contract costs (claims and unapproved change orders). Our contract assets do not include capitalized costs to obtain and fulfill a contract. Contract assets are generally classified as current within the Consolidated Balance Sheets.

Contract liabilities from our long-term construction contracts arise when amounts invoiced to our customers exceed revenues recognized under the cost-to-cost measure of progress. Contract liabilities additionally include advanced payments from our customers on certain contracts. Contract liabilities decrease as we recognize revenue from the satisfaction of the related performance obligation and are recorded as either current or long-term, depending upon when we expect to recognize such revenue. The long-term portion of contract liabilities is included in “Other long-term obligations” in the Consolidated Balance Sheets.

Net contract liabilities consisted of the following (in thousands):

	June 30, 2019			December 31, 2018
Contract assets, current	$	179,439		$	158,243
Contract assets, non-current	—			—
Contract liabilities, current	(544,346		)	(552,290		)
Contract liabilities, non-current	(2,090		)	(2,069		)
Net contract liabilities	$	(366,997	)	$	(396,116	)

The $29.1 million decrease in net contract liabilities for the six months ended June 30, 2019 was primarily attributable to a decrease in net contract liabilities on our uncompleted long-term construction contracts, partially as a result of the timing of billings to our customers. Contract assets and contract liabilities increased by approximately $5.8 million and $10.5 million, respectively, as a result of acquisitions made by us in 2019. There was no significant impairment of contract assets recognized during either period presented.

Transaction Price Allocated to Remaining Unsatisfied Performance Obligations     

The following table presents the transaction price allocated to remaining unsatisfied performance obligations (“remaining performance obligations”) for each of our reportable segments and their respective percentages of total remaining performance obligations (in thousands, except for percentages):

	June 30, 2019		% of Total
Remaining performance obligations:
United States electrical construction and facilities services	$	1,175,333	28	%
United States mechanical construction and facilities services	2,290,438		54	%
United States building services	545,776		13	%
United States industrial services	89,247		2	%
Total United States operations	4,100,794		97	%
United Kingdom building services	125,201		3	%
Total worldwide operations	$	4,225,995	100	%

Our remaining performance obligations at June 30, 2019 were $4.23 billion. Remaining performance obligations increase with awards of new contracts and decrease as we perform work and recognize revenue on existing contracts. We include a project within our remaining performance obligations at such time the project is awarded and agreement on contract terms has been reached. Our remaining performance obligations include amounts related to contracts for which a fixed price contract value is not assigned when a reasonable estimate of total transaction price can be made.

Remaining performance obligations include unrecognized revenues to be realized from uncompleted construction contracts. Although many of our construction contracts are subject to cancellation at the election of our customers, in accordance with industry practice, we do not limit the amount of unrecognized revenue included within remaining performance obligations due to the inherent substantial economic penalty that would be incurred by our customers upon cancellation. We believe our reported remaining performance obligations for our construction contracts are firm and contract cancellations have not had a material adverse effect on us.

Remaining performance obligations also include unrecognized revenues expected to be realized over the remaining term of service contracts. However, to the extent a service contract includes a cancellation clause which allows for the termination of such contract by either party without a substantive penalty, the remaining contract term, and therefore, the amount of unrecognized revenues included within remaining performance obligations, is limited to the notice period required for the termination.

Our remaining performance obligations are comprised of: (a) original contract amounts, (b) change orders for which we have received written confirmations from our customers, (c) pending change orders for which we expect to receive confirmations in the ordinary course of business, (d) claim amounts that we have made against customers for which we have determined we have a legal basis under existing contractual arrangements and as to which the variable consideration constraint does not apply, and (e) other forms of variable consideration to the extent that such variable consideration has been included within the transaction price of our contracts. Such claim and other variable consideration amounts were immaterial for all periods presented.

Refer to the table below for additional information regarding our remaining performance obligations, including an estimate of when we expect to recognize such remaining performance obligations as revenue (in thousands):

	Within one year		Greater than one year
Remaining performance obligations:
United States electrical construction and facilities services	$	1,120,717	$	54,616
United States mechanical construction and facilities services	1,742,820		547,618

NOTE 4 Acquisitions of Businesses     

Acquisitions are accounted for utilizing the acquisition method of accounting and the prices paid for them are allocated to their respective assets and liabilities based on the estimated fair value of such assets and liabilities at the dates of their respective acquisition by us.

During the first half of 2019, we acquired three companies for a total consideration of $64.4 million. In January 2019, we acquired a company which provides mobile mechanical services within the Southern region of the United States. In April 2019, we acquired a company which provides electrical contracting services in central Iowa. In May 2019, we acquired a company which provides building automation and controls solutions within the Western region of the United States. The results of operations for the companies acquired in January and May have been included within our United States building services segment. The results of operations for the company acquired in April have been included within our United States electrical construction and facilities services segment. In connection with these acquisitions, we acquired working capital of $18.5 million and other net assets of $0.2 million and have preliminarily ascribed $22.8 million to goodwill and $22.9 million to identifiable intangible assets.

During calendar year 2018, we acquired four companies for a total consideration of $71.6 million. Two companies provide mobile mechanical services, one within the Eastern region and the other within the Western region of the United States. The third company is a full service provider of mechanical services within the Southern region of the United States. The results of these three companies have been included in our United States building services segment. The fourth company provides electrical construction and maintenance services for industrial and commercial buildings in North Texas, and its results have been included in our United States electrical construction and facilities services segment. In connection with these acquisitions, we acquired working capital of $8.9 million and have preliminarily ascribed $26.1 million to goodwill and $36.6 million to identifiable intangible assets.

We expect that all of the goodwill acquired in connection with these acquisitions will be deductible for tax purposes. The purchase price allocations for the businesses acquired in 2019 and two of the businesses acquired in 2018 are preliminary and subject to change during their respective measurement periods. The purchase price allocations for the remaining two businesses acquired in 2018 have been finalized with an insignificant impact.

NOTE 5 Disposition of Assets    

Due to a historical pattern of losses in the construction operations of our United Kingdom segment and our negative assessment of construction market conditions in the United Kingdom for the foreseeable future, we ceased construction operations in the United Kingdom during the third quarter of 2014. The results of the construction operations of our United Kingdom segment for all periods are presented in the consolidated financial statements as discontinued operations.

No income or expense was recognized from the discontinued operation for the three and six months ended June 30, 2019.

The results of discontinued operations for the three and six months ended June 30, 2018 were as follows (in thousands):

	For the three months ended June 30, 2018			For the six months ended June 30, 2018
Revenues	$	—		$	—
Loss from discontinued operation, net of income taxes	$	(205	)	$	(487	)
Diluted loss per share from discontinued operation	$	(0.00	)	$	(0.01	)

The loss from discontinued operations in 2018 was primarily due to legal costs related to the settlement of final contract balances on certain construction projects completed in prior years.

Included in the Consolidated Balance Sheet at December 31, 2018 were approximately $3.7 million of current liabilities associated with the discontinued operation, primarily consisting of contract retentions, contract warranty obligations and other accrued expenses. No significant liabilities remain as of June 30, 2019.

Credit Agreement        

We have a credit agreement dated as of August 3, 2016, which provides for a $900.0 million revolving credit facility (the “2016 Revolving Credit Facility”) and a $400.0 million term loan (the “2016 Term Loan”) (collectively referred to as the “2016 Credit Agreement”) expiring August 3, 2021. We may increase the 2016 Revolving Credit Facility to $1.3 billion if additional lenders are identified and/or existing lenders are willing to increase their current commitments. We may allocate up to $300.0 million of available capacity under the 2016 Revolving Credit Facility to letters of credit for our account or for the account of any of our subsidiaries. Obligations under the 2016 Credit Agreement are guaranteed by most of our direct and indirect subsidiaries and are secured by substantially all of our assets. The 2016 Credit Agreement contains various covenants providing for, among other things, maintenance of certain financial ratios and certain limitations on payment of dividends, common stock repurchases, investments, acquisitions, indebtedness and capital expenditures. We were in compliance with all such covenants as of June 30, 2019 and December 31, 2018. A commitment fee is payable on the average daily unused amount of the 2016 Revolving Credit Facility, which ranges from 0.15% to 0.30%, based on certain financial tests. The fee was 0.15% of the unused amount as of June 30, 2019. Borrowings under the 2016 Credit Agreement bear interest at (1) a base rate plus a margin of 0.00% to 0.75%, based on certain financial tests, or (2) United States dollar LIBOR (2.40% at June 30, 2019) plus 1.00% to 1.75%, based on certain financial tests. The base rate is determined by the greater of (a) the prime commercial lending rate announced by Bank of Montreal from time to time (5.50% at June 30, 2019), (b) the federal funds effective rate, plus ½ of 1.00%, (c) the daily one month LIBOR rate, plus 1.00%, or (d) 0.00%. The interest rate in effect at June 30, 2019 was 3.40%. Fees for letters of credit issued under the 2016 Revolving Credit Facility range from 1.00% to 1.75% of the respective face amounts of outstanding letters of credit and are computed based on certain financial tests. Debt issuance costs are amortized over the life of the agreement and are included as part of interest expense. The 2016 Term Loan previously required us to make principal payments of $5.0 million on the last day of March, June, September and December of each year, which commenced with the calendar quarter ended December 31, 2016. On December 30, 2016, we made a payment of $100.0 million, of which $5.0 million represented our required quarterly payment and $95.0 million represented a prepayment of outstanding principal. Such prepayment was applied against the remaining mandatory quarterly payments on a ratable basis. As a result, commencing with the calendar quarter ended March 31, 2017, our required quarterly payment has been reduced to $3.8 million. All unpaid principal and interest is due on August 3, 2021. As of June 30, 2019 and December 31, 2018, the balance of the 2016 Term Loan was $262.0 million and $269.6 million, respectively. As of June 30, 2019 and December 31, 2018, we had approximately $109.0 million of letters of credit outstanding. There were $25.0 million in borrowings outstanding under the 2016 Revolving Credit Facility as of June 30, 2019 and December 31, 2018.

NOTE 9 Fair Value Measurements        

We use a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy, which gives the highest priority to quoted prices in active markets, is comprised of the following three levels:

Level 1 – Unadjusted quoted market prices in active markets for identical assets and liabilities.

Level 2 – Observable inputs, other than Level 1 inputs. Level 2 inputs would typically include quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly.

Level 3 – Prices or valuations that require inputs that are both significant to the measurement and unobservable.

The following tables provide the assets and liabilities carried at fair value measured on a recurring basis as of June 30, 2019 and December 31, 2018 (in thousands):  

	Assets at Fair Value as of June 30, 2019
Asset Category	Level 1		Level 2		Level 3		Total
Cash and cash equivalents (1)	$	213,374	$	—	$	—	$	213,374
Restricted cash (2)	2,394		—		—		2,394
Deferred compensation plan assets (3)	29,927		—		—		29,927
Total	$	245,695	$	—	$	—	$	245,695

	Assets at Fair Value as of December 31, 2018
Asset Category	Level 1		Level 2		Level 3		Total
Cash and cash equivalents (1)	$	363,907	$	—	$	—	$	363,907
Restricted cash (2)	2,307		—		—		2,307
Deferred compensation plan assets (3)	23,124		—		—		23,124
Total	$	389,338	$	—	$	—	$	389,338

 ________

(1) Cash and cash equivalents include money market funds with original maturity dates of three months or less, which are Level 1 assets. At June 30, 2019 and December 31, 2018, we had $42.4 million and $161.3 million, respectively, in money market funds.

(2) Restricted cash is classified as “Prepaid expenses and other” in the Consolidated Balance Sheets. Restricted cash primarily represents cash held in account for use on customer contracts.

(3) Deferred compensation plan assets are classified as “Other assets” in the Consolidated Balance Sheets.

We believe that the carrying values of our financial instruments, which include accounts receivable and other financing commitments, approximate their fair values due primarily to their short-term maturities and low risk of counterparty default. The carrying value of our debt associated with the 2016 Credit Agreement approximates its fair value due to the variable rate on such debt. 

NOTE 10 Income Taxes        

In 2018, we finalized our accounting for the income tax effects of the Tax Cuts and Jobs Act (the “Tax Act”). We continue to monitor for potential future changes in certain state and local tax regulations resulting from the Tax Act which may have an impact on our consolidated income tax provision in future periods.

For the three months ended June 30, 2019 and 2018, our income tax provision from continuing operations was $33.2 million and $26.5 million, respectively, based on an effective income tax rate, before discrete items and less amounts attributable to noncontrolling interests, of 28.4% and 27.8%, respectively. The actual income tax rate on income from continuing operations, less amounts attributable to noncontrolling interests, for the three months ended June 30, 2019 and 2018, inclusive of discrete items, was 28.3% and 27.2%, respectively. For the six months ended June 30, 2019 and 2018, our income tax provision from continuing operations was $60.6 million and $47.2 million, respectively, based on an effective income tax rate, before discrete items and less amounts attributable to noncontrolling interests, of 28.2% and 27.7%, respectively. The actual income tax rate on income from continuing operations, less amounts attributable to noncontrolling interests, for the six months ended June 30, 2019 and 2018, inclusive of discrete items, was 27.9% and 27.1%, respectively. The actual income tax rates differed from the statutory tax rate due to state and local income taxes and other permanent book to tax differences. The increase in the 2019 income tax provision was primarily due to increased income from continuing operations. The increase in the actual income tax rate on income from continuing operations for both the three and six months ended June 30, 2019 compared to the three and six months ended

NOTE 10 Income Taxes - (Continued)

June 30, 2018, was primarily due to the continued application of the Tax Act, including the implementation of interpretative guidance issued throughout 2018 regarding certain permanent differences and other non-deductible expenses.

As of June 30, 2019 and December 31, 2018, we had no unrecognized income tax benefits.

We file income tax returns with the Internal Revenue Service and various state, local and foreign tax agencies. The Company is currently under examination by various taxing authorities for the years 2014 through 2017.

NOTE 11 Common Stock        

As of June 30, 2019 and December 31, 2018, there were 56,129,224 and 55,983,763 shares of our common stock outstanding, respectively.

During the three months ended June 30, 2019 and 2018, we issued 44,514 and 72,777 shares of common stock, respectively. During the six months ended June 30, 2019 and 2018, we issued 145,461 and 170,930 shares of common stock, respectively. These shares were issued primarily upon: (a) the satisfaction of required conditions under certain of our share-based compensation plans and (b) the purchase of common stock pursuant to our employee stock purchase plan.

On September 26, 2011, our Board of Directors authorized us to repurchase up to $100.0 million of our outstanding common stock. On December 5, 2013, October 23, 2014, October 28, 2015, October 25, 2017 and October 23, 2018, our Board of Directors authorized us to repurchase up to an additional $100.0 million, $250.0 million, $200.0 million, $100.0 million and $200.0 million of our outstanding common stock, respectively. No shares of our common stock were repurchased during the six months ended June 30, 2019. Since the inception of the repurchase programs through June 30, 2019, we have repurchased approximately 15.9 million shares of our common stock for approximately $791.5 million. As of June 30, 2019, there remained authorization for us to repurchase approximately $158.5 million of our shares. The repurchase programs have no expiration date and do not obligate the Company to acquire any particular amount of common stock and may be suspended, recommenced or discontinued at any time or from time to time without prior notice. We may repurchase our shares from time to time to the extent permitted by securities laws and other legal requirements, including provisions in our 2016 Credit Agreement, placing limitations on such repurchases. The repurchase programs have been and will be funded from our operations.

NOTE 12 Retirement Plans

Our United Kingdom subsidiary has a defined benefit pension plan covering all eligible employees (the “UK Plan”); however, no individual joining the company after October 31, 2001 may participate in the UK Plan. On May 31, 2010, we curtailed the future accrual of benefits for active employees under such plan. We also sponsor three domestic retirement plans in which participation by new individuals is frozen.

Components of Net Periodic Pension Cost

The components of net periodic pension cost (income) of the UK Plan for the three and six months ended June 30, 2019 and 2018 were as follows (in thousands): 

	For the three months ended June 30,						For the six months ended June 30,
	2019			2018			2019			2018
Interest cost	$	2,004		$	2,045		$	4,043		$	4,144
Expected return on plan assets	(3,064		)	(3,490		)	(6,180		)	(7,071		)
Amortization of unrecognized loss	590			665			1,190			1,347
Net periodic pension cost (income)	$	(470	)	$	(780	)	$	(947	)	$	(1,580	)

The net periodic pension cost associated with the domestic plans was approximately $0.1 million for each of the three and six months ended June 30, 2019 and 2018.

Employer Contributions

For the six months ended June 30, 2019, our United Kingdom subsidiary contributed approximately $2.1 million to the UK Plan and anticipates contributing an additional $2.4 million during the remainder of 2019. Contributions to the domestic plans were approximately $0.2 million for the six months ended June 30, 2019.

NOTE 13 Commitments and Contingencies

Government Contracts

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

Legal Proceedings     

We are involved in several legal proceedings in which damages and claims have been asserted against us. We believe that we have a number of valid defenses to such proceedings and claims and intend to vigorously defend ourselves. Other potential claims may exist that have not yet been asserted against us. We do not believe that any such matters will have a material adverse effect on our financial position, results of operations or liquidity. Litigation is subject to many uncertainties and the outcome of litigation is not predictable with assurance. It is possible that some litigation matters for which liabilities have not been recorded could be decided unfavorably to us, and that any such unfavorable decisions could have a material adverse effect on our financial position, results of operations or liquidity.

Restructuring expenses        

Restructuring expenses, relating to employee severance obligations, were $0.2 million and $0.4 million for the three and six months ended June 30, 2019, respectively, and $0.4 million and $0.5 million for the three and six months ended June 30, 2018, respectively. As of June 30, 2019, the balance of restructuring obligations yet to be paid was $0.7 million. Such remaining amounts will be paid pursuant to our contractual obligations throughout 2020 and 2021. No material expenses in connection with restructuring from continuing operations are expected to be incurred during the remainder of 2019.

The changes in restructuring activity by reportable segment during the six months ended June 30, 2019 and 2018 were as follows (in thousands):

NOTE 14 Leases        

On January 1, 2019, we adopted Accounting Standards Codification Topic 842, “Leases” (“ASC 842”). This pronouncement requires lessees to record right-of-use assets and corresponding lease liabilities on the balance sheet for most leases. We adopted this pronouncement utilizing the transition practical expedient which eliminates the requirement that the new lease standard be applied to comparative periods presented in the year of adoption.

As part of our adoption, we elected to utilize the package of practical expedients permitted under the new standard, which allowed us to not reassess: (a) whether an existing contract is or contains a lease, (b) the classification for existing leases and (c) initial direct costs. Further, as permitted by the standard, we made an accounting policy election not to record right-of-use assets or lease liabilities for leases with an initial term of 12 months or less. Instead, consistent with previous accounting guidance, we will recognize payments for such leases in the statement of operations on a straight-line basis over the lease term.

We lease real estate, vehicles and equipment under various operating and finance leases. A lease exists when a contract or part of a contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. In determining whether a lease exists, we consider whether a contract provides us with both: (a) the right to obtain substantially all of the economic benefits from the use of the identified asset and (b) the right to direct the use of the identified asset.

NOTE 14 Leases - (Continued)

Many of our leases include base rental periods coupled with options to renew or terminate the lease, generally at our discretion. Certain leases additionally include options to purchase the leased asset. In evaluating the lease term, we consider whether we are reasonably certain to exercise such options. To the extent a significant economic incentive exists to exercise an option, that option is included within the lease term. However, based on the nature of our lease arrangements, options generally do not provide us with a significant economic incentive and are therefore excluded from the lease term for the majority of our arrangements.

Our leases typically include a combination of fixed and variable payments. Fixed payments are generally included when measuring the right-of-use asset and lease liability. Variable payments, which primarily represent payments based on usage of the underlying asset, are generally excluded from such measurement and expensed as incurred. In addition, certain of our lease arrangements may contain a lease coupled with an arrangement to provide other services, such as maintenance, or may require us to make other payments on behalf of the lessor related to the leased asset, such as payments for taxes or insurance. As permitted by ASC 842, we have elected to account for these non-lease components together with the associated lease component. This election has been made for each of our asset classes.

The measurement of right-of-use assets and lease liabilities requires us to estimate appropriate discount rates. To the extent the rate implicit in the lease is readily determinable, such rate is utilized. However, based on information available at lease commencement for the majority of our leases, the rate implicit in the lease is not known. In these instances, we utilize an incremental borrowing rate, which represents the rate of interest that we would pay to borrow on a collateralized basis over a similar term.

Our lease arrangements generally do not contain significant restrictions or covenants; however, certain of our vehicle and equipment leases include residual value guarantees, whereby we provide a guarantee to the lessor that the value of the underlying asset will be at least a specified amount at the end of the lease. Amounts probable of being owed under these guarantees are included within the measurement of the right-of-use asset and lease liability.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

We are one of the largest electrical and mechanical construction and facilities services firms in the United States. In addition, we provide a number of building services and industrial services. Our services are provided to a broad range of commercial, industrial, utility and institutional customers through approximately 80 operating subsidiaries and joint venture entities. Our offices are located in the United States and the United Kingdom.

Operating Segments

Our reportable segments reflect certain reclassifications of prior year amounts from our United States mechanical construction and facilities services segment to our United States industrial services segment due to changes in our internal reporting structure.

We have the following reportable segments, which provide services associated with the design, integration, installation, start-up, operation and maintenance of various systems: (a) United States electrical construction and facilities services (involving systems for electrical power transmission and distribution; premises electrical and lighting systems; process instrumentation in the refining, chemical processing, food processing and mining industries; low-voltage systems, such as fire alarm, security and process control; voice and data communication; roadway and transit lighting; and fiber optic lines); (b) United States mechanical construction and facilities services (involving systems for heating, ventilation, air conditioning, refrigeration and clean-room process ventilation; fire protection; plumbing, process and high-purity piping; controls and filtration; water and wastewater treatment; central plant heating and cooling; cranes and rigging; millwrighting; and steel fabrication, erection and welding); (c) United States building services; (d) United States industrial services; and (e) United Kingdom building services. The “United States building services” and “United Kingdom building services” segments principally consist of those operations which provide a portfolio of services needed to support the operation and maintenance of customers’ facilities, including commercial and government site-based operations and maintenance; facility maintenance and services, including reception, security and catering services; outage services to utilities and industrial plants; military base operations support services; mobile mechanical maintenance and services; floor care and janitorial services; landscaping, lot sweeping and snow removal; facilities management; vendor management; call center services; installation and support for building systems; program development, management and maintenance for energy systems; technical consulting and diagnostic services; infrastructure and building projects for federal, state and local governmental agencies and bodies; and small modification and retrofit projects, which services are not generally related to customers’ construction programs. The “United States industrial services” segment principally consists of those operations which provide industrial maintenance and services, including those for refineries and petrochemical plants, including on-site repairs, maintenance and service of heat exchangers, towers, vessels and piping; design, manufacturing, repair and hydro blast cleaning of shell and tube heat exchangers and related equipment; refinery turnaround planning and engineering services; specialty welding services; overhaul and maintenance of critical process units in refineries and petrochemical plants; and specialty technical services for refineries and petrochemical plants.

Overview

The following table presents selected financial data for the three months ended June 30, 2019 and 2018 (in thousands, except percentages and per share data): 

	For the three months ended June 30,
	2019			2018
Revenues	$	2,324,202		$	1,953,886
Revenues increase from prior year	19.0		%	3.1		%
Operating income	$	119,959		$	99,656
Operating income as a percentage of revenues	5.2		%	5.1		%
Net income attributable to EMCOR Group, Inc.	$	83,972		$	70,816
Diluted earnings per common share from continuing operations	$	1.49		$	1.21

The results for the three months ended June 30, 2019 set new company records in terms of quarterly revenues, operating income, net income attributable to EMCOR Group, Inc. and diluted earnings per common share from continuing operations. Revenues for the second quarter of 2019 increased by 19.0% from $1.95 billion for the three months ended June 30, 2018 to $2.32 billion for the three months ended June 30, 2019. Operating income for the three months ended June 30, 2019 of $120.0 million, or 5.2% of revenues, increased by $20.3 million compared to operating income of $99.7 million, or 5.1% of revenues, for the three months ended June 30, 2018.

28

The strong operating results were due to revenue growth and an increase in operating income within all of our reportable segments, as well as operating margin (operating income as a percentage of revenues) expansion across all such segments, except for our United States mechanical construction and facilities services segment.

Impact of Acquisitions

In order to provide a more meaningful period-over-period discussion of our operating results, we may discuss amounts generated or incurred (revenues, gross profit, selling, general and administrative expenses, and operating income) from companies acquired. The amounts discussed reflect the acquired companies’ operating results in the current reported period only for the time period these entities were not owned by EMCOR in the comparable prior reported period.

In January 2019, we acquired a company which provides mobile mechanical services within the Southern region of the United States. Its results have been included within our United States building services segment. In April 2019, we acquired a company which provides electrical contracting services in central Iowa. Its results have been included in our United States electrical construction and facilities services segment. In May 2019, we acquired a company which provides building automation and controls solutions within the Western region of the United States. The results of operations for this company, which have been included within our United States building services segment, were de mimimis.

We acquired four companies in calendar year 2018. Two companies provide mobile mechanical services, one within the Eastern region and the other within the Western region of the United States. The third company is a full service provider of mechanical services within the Southern region of the United States. The results of these three companies have been included in our United States building services segment. The fourth company provides electrical construction and maintenance services for industrial and commercial buildings in North Texas, and its results have been included in our United States electrical construction and facilities services segment.

Companies acquired in 2019 and 2018 generated incremental revenues of $72.8 million and incremental operating income of $5.2 million, inclusive of $1.9 million of amortization expense associated with identifiable intangible assets, for the three months ended June 30, 2019.

As described below in more detail, our revenues for the three months ended June 30, 2019 increased to $2.32 billion compared to $1.95 billion for the three months ended June 30, 2018, and our revenues for the six months ended June 30, 2019 increased to $4.48 billion compared to $3.85 billion for the six months ended June 30, 2018. The increase in revenues for both periods was attributable to increased revenues from all of our reportable segments. Companies acquired in 2019 and 2018, which are reported in our United States electrical construction and facilities services segment and our United States building services segment, generated incremental revenues of $72.8 million and $121.2 million for the three and six months ended June 30, 2019, respectively.

Revenues of our United States electrical construction and facilities services segment were $569.4 million and $1,097.5 million for the three and six months ended June 30, 2019, respectively, compared to revenues of $479.5 million and $934.3 million for the three and six months ended June 30, 2018, respectively. The increase in revenues for the three and six months ended June 30, 2019 was attributable to: (a) an increase in revenues from the commercial market sector, primarily as a result of several large telecommunication construction projects, and (b) an increase in project activities within the manufacturing market sector. In addition, the results for the three and six months ended June 30, 2019 included $44.7 million and $63.0 million, respectively, of incremental revenues generated by companies acquired in 2019 and 2018. These increases were partially offset by a decrease in revenues due to the completion or substantial completion of certain construction projects within the transportation and healthcare market sectors.

Our United States mechanical construction and facilities services segment revenues for the three months ended June 30, 2019 were $823.1 million, a $99.2 million increase compared to revenues of $723.9 million for the three months ended June 30, 2018. Revenues of this segment for the six months ended June 30, 2019 were $1,575.5 million, a $166.9 million increase compared to revenues of $1,408.6 million for the six months ended June 30, 2018. The increase in revenues for the three and six months ended June 30, 2019 was primarily attributable to an increase in revenues from: (a) the manufacturing market sector, due to several new contract awards, including certain food processing construction projects, (b) the commercial market sector, due to increased project activity, inclusive of certain telecommunication and technology construction contracts, and (c) the healthcare, transportation, and water and wastewater market sectors. These increases were partially offset by decreased revenues within the hospitality and institutional market sectors.

Revenues of our United States building services segment were $523.7 million and $1,035.8 million for the three and six months ended June 30, 2019, respectively, compared to revenues of $461.0 million and $915.8 million for the three and six months ended June 30, 2018, respectively. The increase in revenues for both periods was due to: (a) greater project, controls and service activities within our mobile mechanical services operations, (b) increased large project activity within our energy services operations and (c) a net increase in revenues from existing customers within our commercial site-based services operations, partially as a result of scope expansion on certain contracts. In addition, the results for the three and six months ended June 30, 2019 included $28.1 million and $58.2 million, respectively, of incremental revenues generated by companies acquired in 2019 and 2018. These increases were partially offset by a decrease in revenues due to the loss of certain contracts not renewed pursuant to rebid within our government site-based services operations.

Revenues of our United States industrial services segment for the three months ended June 30, 2019 were $295.5 million, a $111.5 million increase compared to revenues of $183.9 million for the three months ended June 30, 2018. Revenues for the six months ended June 30, 2019 were $554.1 million, a $170.9 million increase compared to revenues of $383.2 million for the six months ended June 30, 2018. The increase in revenues for the three and six months ended June 30, 2019 was primarily due to an increase in revenues from our field services operations as such businesses experienced a more normalized demand pattern compared to the prior year, which was negatively impacted by the cancellation or deferral of certain previously scheduled maintenance activities with our customers. In addition, the results for the six months ended June 30, 2019 were favorably impacted by increased revenues from our shop services operations as a result of increased new build heat exchanger sales and an increase in maintenance, repair and hydro blast cleaning services.

Our United Kingdom building services segment revenues for the three months ended June 30, 2019 increased by $7.0 million compared to the three months ended June 30, 2018. Revenues of this segment for the six months ended June 30, 2019 increased by $7.7 million compared to the six months ended June 30, 2018. The increase in revenues for both periods was primarily the result of: (a) increased project activity with existing customers and (b) new contract awards within the commercial market sector. This segment’s revenues for the three and six months ended June 30, 2019 were negatively impacted by $6.6 million and $14.0 million, respectively, related to the effect of unfavorable exchange rates for the British pound versus the United States dollar.

Cost of sales and Gross profit

The following table presents our cost of sales, gross profit (revenues less cost of sales) and gross profit margin (gross profit as a percentage of revenues) (in thousands, except for percentages): 

	For the three months ended June 30,						For the six months ended June 30,
	2019			2018			2019			2018
Cost of sales	$	1,977,822		$	1,663,042		$	3,827,796		$	3,294,311
Gross profit	$	346,380		$	290,844		$	655,134		$	559,963
Gross profit, as a percentage of revenues	14.9		%	14.9		%	14.6		%	14.5		%

Our gross profit increased by $55.5 million for the three months ended June 30, 2019 compared to the three months ended June 30, 2018. Gross profit increased by $95.2 million for the six months ended June 30, 2019 compared to the six months ended June 30, 2018. Our gross profit margin was 14.9% and 14.6% for the three and six months ended June 30, 2019, respectively, compared to gross profit margin of 14.9% and 14.5% for the three and six months ended June 30, 2018, respectively. The increase in gross profit for the three and six months ended June 30, 2019 was the result of an increase in gross profit from all of our reportable segments except, in the case of the three months ended June 30, 2019, our United States mechanical construction and facilities services segment. The increased gross profit within each such segment was attributable to an increase in revenues during the respective period.

Selling, general and administrative expenses

The following table presents our selling, general and administrative expenses and SG&A margin (selling, general and administrative expenses as a percentage of revenues) (in thousands, except for percentages): 

	For the three months ended June 30,						For the six months ended June 30,
	2019			2018			2019			2018
Selling, general and administrative expenses	$	226,248		$	189,907		$	432,417		$	380,932
Selling, general and administrative expenses, as a percentage of revenues	9.7		%	9.7		%	9.6		%	9.9		%

Our selling, general and administrative expenses for the three months ended June 30, 2019 increased by $36.3 million to $226.2 million compared to $189.9 million for the three months ended June 30, 2018. Selling, general and administrative expenses for the six months ended June 30, 2019 increased by $51.5 million to $432.4 million compared to $380.9 million for the six months ended June 30, 2018. The increase in selling, general and administrative expenses for the three and six months ended June 30, 2019 included $9.5 million and $16.7 million, respectively, of incremental expenses directly related to companies acquired in 2019 and 2018, including amortization expense attributable to identifiable intangible assets of $0.8 million and $1.5 million, respectively. In addition to the impact of acquisitions, selling, general and administrative expenses increased due to: (a) an increase in salaries and related employment costs, partially as a result of an increase in headcount due to higher revenues than in the same prior year period, (b) an increase in incentive compensation expense, due to higher projected annual operating results than in the same prior year period, (c) an increase in information technology costs related to certain initiatives currently in process and (d) an increase in the provision for doubtful accounts, primarily within our United States electrical constructions and facilities services segment.

Selling, general and administrative expenses as a percentage of revenues were 9.7% and 9.6% for the three and six months ended June 30, 2019, respectively, compared to 9.7% and 9.9% for the three and six months ended June 30, 2018, respectively. The decrease in SG&A margin for the six months ended June 30, 2019 compared to the six months ended June 30, 2018 was primarily due to an increase in revenues without commensurate increases in our overhead cost structure.

Restructuring expenses    

Restructuring expenses, relating to employee severance obligations, were $0.2 million and $0.4 million for the three and six months ended June 30, 2019, respectively, and $0.4 million and $0.5 million for the three and six months ended June 30, 2018, respectively. As of June 30, 2019, the balance of restructuring obligations yet to be paid was $0.7 million. Such remaining amounts will be paid pursuant to our contractual obligations throughout 2020 and 2021. No material expenses in connection with restructuring from continuing operations are expected to be incurred during the remainder of 2019.

As described below in more detail, operating income was $120.0 million and $222.3 million for the three and six months ended June 30, 2019, respectively, compared to $99.7 million and $177.7 million for the three and six months ended June 30, 2018, respectively. The increase in operating income for the three and six months ended June 30, 2019 was the result of an increase in gross profit from all of our reportable segments except, in the case of the three months ended June 30, 2019, our United States mechanical construction and facilities services segment. Operating margin was 5.2% and 5.0% for the three and six months ended June 30, 2019, respectively, compared to 5.1% and 4.6% for the three and six months ended June 30, 2018, respectively. Operating margin for both periods increased within all of our reportable segments, except for our United States mechanical construction and facilities services segment.

32

Operating income of our United States electrical construction and facilities services segment for the three months ended June 30, 2019 was $43.8 million, a $7.8 million increase compared to operating income of $36.0 million for the three months ended June 30, 2018. Operating income for the six months ended June 30, 2019 was $86.8 million, a $14.9 million increase compared to operating income of $71.8 million for the six months ended June 30, 2018. The increase in operating income for the three and six months ended June 30, 2019 was primarily attributable to an increase in gross profit within the commercial market sector, inclusive of certain telecommunication construction projects, partially offset by a decrease in gross profit within the transportation market sector as a result of the completion or substantial completion of certain construction projects. Additionally, companies acquired in 2019 and 2018 contributed incremental operating income of $2.2 million and $2.3 million, inclusive of $0.6 million and $1.1 million of amortization expense associated with identifiable intangible assets, for the three and six months ended June 30, 2019, respectively. The increase in operating margin for the three and six months ended June 30, 2019 was attributable to an increase in gross profit margin due to favorable revenue mix and project execution throughout this segment.

Our United States mechanical construction and facilities services segment operating income for the three and six months ended June 30, 2019 was $54.0 million and $94.9 million, respectively, compared to operating income of $57.4 million and $97.0 million for the three and six months ended June 30, 2018, respectively. The decrease in operating income for the three and six months ended June 30, 2019 was partially attributable to: (a) the mix of work within the manufacturing market sector, including projects which are in the earlier stages of completion and typically carry lower gross profit margins, and (b) a decrease in gross profit from construction projects within the transportation market sector due to the completion of certain projects in the prior year. Additionally, the decrease in operating income for the three months ended June 30, 2019 was the result of a decrease in gross profit from activities within the hospitality market sector due to the substantial completion of certain large projects. The decrease in operating income for the six months ended June 30, 2019 was partially offset by an increase in gross profit within the commercial market sector, inclusive of certain telecommunication and technology projects currently in process. The decrease in operating margin for the three and six months ended June 30, 2019 was attributable to a decrease in gross profit margin, primarily within the manufacturing market sector, as referenced above.

Operating income of our United States building services segment for the three months ended June 30, 2019 increased by $5.6 million compared to operating income for the three months ended June 30, 2018. Operating income of this segment for the six months ended June 30, 2019 increased by $16.0 million compared to the six months ended June 30, 2018. The increase in operating income for the three and six months ended June 30, 2019 was primarily attributable to: (a) our mobile mechanical services operations, as a result of increased gross profit from project, controls and repair activities, (b) our energy services operations, due to an increase in large project activity, and (c) our commercial site-based services operations, as a result of scope expansion on existing contracts. Additionally, companies acquired in 2019 and 2018 contributed incremental operating income of $3.0 million and $5.0 million, inclusive of $1.3 million and $2.8 million of amortization expense associated with identifiable intangible assets, for the three and six months ended June 30, 2019, respectively. The increase in operating margin for the three and six months ended June 30, 2019 was attributable to an increase in gross profit margin, primarily from project, controls, and repair activities within our mobile mechanical services operations.

Our United States industrial services segment operating income for the three months ended June 30, 2019 was $16.0 million compared to operating income of $1.2 million for the three months ended June 30, 2018. Operating income of this segment for the six months ended June 30, 2019 was $25.6 million compared to operating income of $4.7 million for the six months ended June 30, 2018. The $14.8 million and $21.0 million increases in operating income for the three and six months ended June 30, 2019, respectively, were primarily due to an increase in demand for our service offerings, as well as improved operating performance within both our field and shop services operations. Additionally, the results for the six months ended June 30, 2019 benefited from the recovery of $3.6 million associated with a legal settlement, which has been recorded as a reduction to selling, general and administrative expenses. The increase in operating margin for the three and six months ended June 30, 2019 was attributable to: (a) an increase in gross profit margin, primarily as a result of a favorable mix of work, and (b) a decrease in the ratio of selling, general and administrative expenses to revenues due to: (i) an increase in revenues without commensurate increases in this segment’s overhead cost structure and (ii) the legal settlement referenced above.

Our United Kingdom building services segment operating income was $5.5 million for the three months ended June 30, 2019 compared to operating income of $4.6 million for the three months ended June 30, 2018. Operating income for the six months ended June 30, 2019 was $9.6 million compared to operating income of $8.4 million for the six months ended June 30, 2018. Operating income for the three and six months ended June 30, 2019 increased primarily due to: (a) an increase in gross profit from project activity with existing customers within the commercial and institutional market sectors and (b) new contract awards within the commercial market sector. This segment’s operating income was negatively impacted by $0.3 million and $0.6 million for the three and six months ended June 30, 2019, respectively, related to the effect of unfavorable exchange rates for the British pound versus the United States dollar. The increase in operating margin for the three and six months ended June 30, 2019 was primarily attributable to an increase in gross profit margin and a decrease in the ratio of selling, general and administrative expenses to revenues.

33

Our corporate administration operating loss for the three and six months ended June 30, 2019 was $27.1 million and $49.7 million, respectively, compared to $20.7 million and $42.4 million for the three and six months ended June 30, 2018, respectively. The increase in corporate administration expenses for the three and six months ended June 30, 2019 was primarily due to an increase in employment costs, such as incentive compensation and salaries, as well as an increase in professional fees as a result of certain information technology initiatives currently in process.

Net interest expense for the three months ended June 30, 2019 and 2018 was $3.2 million and $2.8 million, respectively. Net interest expense for the six months ended June 30, 2019 and 2018 was $6.1 million and $5.3 million, respectively. Net interest expense for the three months ended June 30, 2019 and 2018 consisted of interest expense of $3.5 million in each period, partially offset by interest income of $0.3 million and $0.6 million, respectively. Net interest expense for the six months ended June 30, 2019 and 2018 consisted of interest expense of $7.1 million and $6.5 million, respectively, partially offset by interest income of $1.0 million and $1.2 million, respectively. The increase in net interest expense for the three and six months ended June 30, 2019 was due to: (a) the impact of higher interest rates on interest expense, partially offset by the impact of decreased average outstanding borrowings, and (b) reduced interest income as a result of lower average daily cash balances.

For the three months ended June 30, 2019 and 2018, our income tax provision from continuing operations was $33.2 million and $26.5 million, respectively, based on an effective income tax rate, before discrete items and less amounts attributable to noncontrolling interests, of 28.4% and 27.8%, respectively. The actual income tax rate on income from continuing operations, less amounts attributable to noncontrolling interests, for the three months ended June 30, 2019 and 2018, inclusive of discrete items, was 28.3% and 27.2%, respectively. For the six months ended June 30, 2019 and 2018, our income tax provision from continuing operations was $60.6 million and $47.2 million, respectively, based on an effective income tax rate, before discrete items and less amounts attributable to noncontrolling interests, of 28.2% and 27.7%, respectively. The actual income tax rate on income from continuing operations, less amounts attributable to noncontrolling interests, for the six months ended June 30, 2019 and 2018, inclusive of discrete items, was 27.9% and 27.1%, respectively. The increase in the 2019 income tax provision was primarily due to increased income from continuing operations. The increase in the actual income tax rate on income from continuing operations for both the three and six months ended June 30, 2019 compared to the three and six months ended June 30, 2018, was primarily due to the continued application of the Tax Cuts and Jobs Act, including the implementation of interpretative guidance issued throughout 2018 regarding certain permanent differences and other non-deductible expenses.

Discontinued operations

Due to a historical pattern of losses in the construction operations of our United Kingdom segment and our negative assessment of construction market conditions in the United Kingdom for the foreseeable future, we ceased construction operations in the United Kingdom during the third quarter of 2014. The results of the construction operations of our United Kingdom segment for all periods are presented in the consolidated financial statements as discontinued operations.

Remaining Unsatisfied Performance Obligations    

The following table presents the transaction price allocated to remaining unsatisfied performance obligations (“remaining performance obligations”) for each of our reportable segments and their respective percentage total of remaining performance obligations (in thousands, except for percentages):

	June 30, 2019		% of Total		December 31, 2018		% of Total		June 30, 2018		% of Total
Remaining performance obligations:
United States electrical construction and facilities services	$	1,175,333	28	%	$	1,085,571	27	%	$	1,037,796	28	%
United States mechanical construction and facilities services	2,290,438		54	%	2,226,183		57	%	1,954,999		53	%
United States building services	545,776		13	%	435,074		11	%	451,960		12	%
United States industrial services	89,247		2	%	86,930		2	%	98,034		3	%
Total United States operations	4,100,794		97	%	3,833,758		97	%	3,542,789		96	%
United Kingdom building services	125,201		3	%	130,524		3	%	130,342		4	%
Total worldwide operations	$	4,225,995	100	%	$	3,964,282	100	%	$	3,673,131	100	%

Remaining performance obligations increase with awards of new contracts and decrease as we perform work and recognize revenue on existing contracts. We include a project within our remaining performance obligations at such time as the project is awarded and agreement on contract terms has been reached. Our remaining performance obligations include amounts related to contracts for which a fixed price contract value is not assigned when a reasonable estimate of total transaction price can be made.

34

Remaining performance obligations include unrecognized revenues to be realized from uncompleted construction contracts. Although many of our construction contracts are subject to cancellation at the election of our customers, in accordance with industry practice, we do not limit the amount of unrecognized revenue included within remaining performance obligations due to the inherent substantial economic penalty that would be incurred by our customers upon cancellation. We believe our reported remaining performance obligations for our construction contracts are firm and contract cancellations have not had a material adverse effect on us.

Remaining performance obligations also include unrecognized revenues expected to be realized over the remaining term of service contracts. However, to the extent a service contract includes a cancellation clause which allows for the termination of such contract by either party without a substantive penalty, the remaining contract term, and therefore, the amount of unrecognized revenues included within remaining performance obligations, is limited to the notice period required for the termination.

Our remaining performance obligations are comprised of: (a) original contract amounts, (b) change orders for which we have received written confirmations from our customers, (c) pending change orders for which we expect to receive confirmations in the ordinary course of business, (d) claim amounts that we have made against customers for which we have determined we have a legal basis under existing contractual arrangements and as to which the variable consideration constraint does not apply, and (e) other forms of variable consideration to the extent that such variable consideration has been included within the transaction price of our contracts. Such claim and other variable consideration amounts were immaterial for all periods presented.

Our remaining performance obligations at June 30, 2019 were $4.23 billion compared to $3.96 billion at December 31, 2018 and $3.67 billion at June 30, 2018. The increase in remaining performance obligations at June 30, 2019 compared to December 31, 2018 was attributable to an increase in remaining performance obligations within all of our reportable segments, except for our United Kingdom building services segment.

Liquidity and Capital Resources        

The following table presents our net cash used in operating activities, investing activities and financing activities (in thousands):     

	For the six months ended June 30,
	2019			2018
Net cash used in operating activities	$	(42,198	)	$	(32,650	)
Net cash used in investing activities	$	(85,830	)	$	(43,917	)
Net cash used in financing activities	$	(22,243	)	$	(82,504	)
Effect of exchange rate changes on cash, cash equivalents and restricted cash	$	(175	)	$	(1,121	)

Our consolidated cash balance, including cash equivalents and restricted cash, decreased by approximately $150.4 million from $366.2 million at December 31, 2018 to $215.8 million at June 30, 2019. Net cash used in operating activities for the six months ended June 30, 2019 was $42.2 million compared to $32.7 million for the six months ended June 30, 2018. The increase in cash used in operating activities was primarily due to significant organic revenue growth during the period, which resulted in increased working capital levels. Net cash used in investing activities was $85.8 million for the six months ended June 30, 2019 compared to $43.9 million for the six months ended June 30, 2018. The increase in net cash used in investing activities was primarily due to an increase in payments for acquisitions of businesses and purchases of property, plant and equipment. Net cash used in financing activities for the six months ended June 30, 2019 decreased by approximately $60.3 million compared to the six months ended June 30, 2018, primarily as a result of a decrease in funds used for the repurchase of our common stock. Cash flows from discontinued operations were immaterial and are not expected to significantly affect future liquidity.

(1) On August 3, 2016, we entered into a $900.0 million revolving credit facility (the “2016 Revolving Credit Facility”) and a $400.0 million term loan (the “2016 Term Loan”) (collectively referred to as the “2016 Credit Agreement”). As of June 30, 2019, the amounts outstanding under the 2016 Term Loan and the 2016 Revolving Credit Facility were $262.0 million and $25.0 million, respectively.

(2) Represents open purchase orders for material and subcontracting costs related to construction and services contracts. These purchase orders are not reflected in EMCOR’s Consolidated Balance Sheets and should not impact future cash flows as amounts should be recovered through customer billings.

(3) Primarily represents insurance related liabilities and liabilities for deferred income taxes, incentive compensation and deferred compensation, classified as other long-term liabilities in the Consolidated Balance Sheets. Cash payments for insurance and deferred compensation related liabilities may be payable beyond three years, however it is not practical to estimate these payments; therefore, these liabilities are reflected in the 1-3 years payment period. We provide funding to our post retirement plans based on at least the minimum funding required by applicable regulations. In determining the minimum required funding, we utilize current actuarial assumptions and exchange rates to forecast amounts that may be payable for up to five years in the future. In our judgment, minimum funding estimates beyond a five year time horizon cannot be reliably estimated and, therefore, have not been included in the table.

We have a credit agreement dated as of August 3, 2016, which provides for a $900.0 million revolving credit facility (the “2016 Revolving Credit Facility”) and a $400.0 million term loan (the “2016 Term Loan”) (collectively referred to as the “2016 Credit Agreement”) expiring August 3, 2021. We may increase the 2016 Revolving Credit Facility to $1.3 billion if additional lenders are identified and/or existing lenders are willing to increase their current commitments. We may allocate up to $300.0 million of available capacity under the 2016 Revolving Credit Facility to letters of credit for our account or for the account of any of our subsidiaries. Obligations under the 2016 Credit Agreement are guaranteed by most of our direct and indirect subsidiaries and are secured by substantially all of our assets. The 2016 Credit Agreement contains various covenants providing for, among other things, maintenance of certain financial ratios and certain limitations on payment of dividends, common stock repurchases, investments, acquisitions, indebtedness and capital expenditures. We were in compliance with all such covenants as of June 30, 2019 and December 31, 2018. A commitment fee is payable on the average daily unused amount of the 2016 Revolving Credit Facility, which ranges from 0.15% to 0.30%, based on certain financial tests. The fee was 0.15% of the unused amount as of June 30, 2019. Borrowings under the 2016 Credit Agreement bear interest at (1) a base rate plus a margin of 0.00% to 0.75%, based on certain financial tests, or (2) United States dollar LIBOR (2.40% at June 30, 2019) plus 1.00% to 1.75%, based on certain financial tests. The base rate is determined by the greater of (a) the prime commercial lending rate announced by Bank of Montreal from time to time (5.50% at June 30, 2019), (b) the federal funds effective rate, plus ½ of 1.00%, (c) the daily one month LIBOR rate, plus 1.00%, or (d) 0.00%. The interest rate in effect at June 30, 2019 was 3.40%. Fees for letters of credit issued under the 2016 Revolving Credit Facility range from 1.00% to 1.75% of the respective face amounts of outstanding letters of credit and are computed based on certain financial tests. Debt issuance costs are amortized over the life of the agreement and are included as part of interest expense. The 2016 Term Loan previously required us to make principal payments of $5.0 million on the last day of March, June, September and December of each year, which commenced with the calendar quarter ended December 31, 2016. On December 30, 2016, we made a payment of $100.0 million, of which $5.0 million represented our required quarterly payment and $95.0 million represented a prepayment of outstanding principal. Such prepayment was applied against the remaining mandatory quarterly payments on a ratable basis. As a result, commencing with the calendar quarter ended March 31, 2017, our required quarterly payment has been reduced to $3.8 million. All unpaid principal and interest is due on August 3, 2021. As of

36

June 30, 2019 and December 31, 2018, the balance of the 2016 Term Loan was $262.0 million and $269.6 million, respectively. As of June 30, 2019 and December 31, 2018, we had approximately $109.0 million of letters of credit outstanding. There were $25.0 million in borrowings outstanding under the 2016 Revolving Credit Facility as of June 30, 2019 and December 31, 2018.

The terms of our construction contracts frequently require that we obtain from surety companies (“Surety Companies”) and provide to our customers payment and performance bonds (“Surety Bonds”) as a condition to the award of such contracts. The Surety Bonds secure our payment and performance obligations under such contracts, and we have agreed to indemnify the Surety Companies for amounts, if any, paid by them in respect of Surety Bonds issued on our behalf. In addition, at the request of labor unions representing certain of our employees, Surety Bonds are sometimes provided to secure obligations for wages and benefits payable to or for such employees. Public sector contracts require Surety Bonds more frequently than private sector contracts and, accordingly, our bonding requirements typically increase as the amount of public sector work increases. As of June 30, 2019, based on the percentage-of-completion of our projects covered by Surety Bonds, our aggregate estimated exposure, assuming defaults on all our then existing contractual obligations, was approximately $1.3 billion. Surety Bonds are issued by Surety Companies in return for premiums, which vary depending on the size and type of bond.

From time to time, we discuss with our current and other Surety Bond providers the amounts of Surety Bonds that may be available to us based on our financial strength and the absence of any default by us on any Surety Bond issued on our behalf and believe those amounts are currently adequate for our needs. However, if we experience changes in our bonding relationships or if there are adverse changes in the surety industry, we may (i) seek to satisfy certain customer requests for Surety Bonds by posting other forms of collateral in lieu of Surety Bonds, such as letters of credit, parent company guarantees or cash, in order to convince customers to forego the requirement for Surety Bonds, (ii) increase our activities in our business segments that rarely require Surety Bonds, such as our building and industrial services segments, and/or (iii) refrain from bidding for certain projects that require Surety Bonds. There can be no assurance that we would be able to effectuate alternatives to providing Surety Bonds to our customers or to obtain, on favorable terms, sufficient additional work that does not require Surety Bonds. Accordingly, if we were to experience a reduction in the availability of Surety Bonds, we could experience a material adverse effect on our financial position, results of operations and/or cash flows.

In the ordinary course of business, we, at times, guarantee obligations of our subsidiaries under certain contracts. Generally, we are liable under such an arrangement only if our subsidiary fails to perform its obligations under the contract. Historically, we have not incurred any substantial liabilities as a consequence of these guarantees.

We do not have any other material financial guarantees or off-balance sheet arrangements other than those disclosed herein.

We are a party to lawsuits and other proceedings in which other parties seek to recover amounts from us. While litigation is subject to many uncertainties and the outcome of litigation is not predictable with assurance, we do not believe that any such matters will have a material adverse effect on our financial position, results of operations or liquidity.

On September 26, 2011, our Board of Directors authorized us to repurchase up to $100.0 million of our outstanding common stock. On December 5, 2013, October 23, 2014, October 28, 2015, October 25, 2017 and October 23, 2018, our Board of Directors authorized us to repurchase up to an additional $100.0 million, $250.0 million, $200.0 million, $100.0 million and $200.0 million of our outstanding common stock, respectively. No shares of our common stock were repurchased during the six months ended June 30, 2019. Since the inception of the repurchase programs through June 30, 2019, we have repurchased approximately 15.9 million shares of our common stock for approximately $791.5 million. As of June 30, 2019, there remained authorization for us to repurchase approximately $158.5 million of our shares. The repurchase programs have no expiration date and do not obligate the Company to acquire any particular amount of common stock and may be suspended, recommenced or discontinued at any time or from time to time without prior notice. We may repurchase our shares from time to time to the extent permitted by securities laws and other legal requirements, including provisions in our 2016 Credit Agreement, placing limitations on such repurchases. The repurchase programs have been and will be funded from our operations.

We have paid quarterly dividends since October 25, 2011. We currently pay a regular quarterly dividend of $0.08 per share. Our 2016 Credit Agreement places limitations on the payment of dividends on our common stock. However, we do not believe that the terms of such agreement currently materially limit our ability to pay a quarterly dividend of $0.08 per share for the foreseeable future. The payment of dividends has been and will be funded from our operations.

Our primary source of liquidity has been, and is expected to continue to be, cash generated by operating activities. We also maintain our 2016 Revolving Credit Facility that may be utilized, among other things, to meet short-term liquidity needs in the event cash generated by operating activities is insufficient or to enable us to participate in joint ventures or to make acquisitions that may require access to cash on short notice or for any other reason. Negative macroeconomic trends may have an adverse effect on liquidity. During economic downturns, there have typically been fewer small discretionary projects from the private sector, and our competitors have aggressively bid larger long-term infrastructure and public sector contracts. Short-term liquidity is also impacted by the type and length of construction contracts in place and large turnaround activities in our United States

37

industrial services segment that are billed in arrears pursuant to contractual terms that are standard within the industry. Performance of long duration contracts typically requires greater amounts of working capital. While we strive to negotiate favorable billing terms which allow us to invoice in advance of costs incurred on certain of our contracts, there can be no assurance that such terms will be agreed to by our customers.

Long-term liquidity requirements can be expected to be met initially through cash generated from operating activities and our 2016 Revolving Credit Facility. Based upon our current credit ratings and financial position, we can reasonably expect to be able to incur long-term debt to fund acquisitions. Over the long term, our primary revenue risk factor continues to be the level of demand for non-residential construction services and for building and industrial services, which is influenced by macroeconomic trends including interest rates and governmental economic policy. In addition, our ability to perform work is critical to meeting long-term liquidity requirements.

We believe that our current cash balances and our borrowing capacity available under our 2016 Revolving Credit Facility or other forms of financing available to us through borrowings, combined with cash expected to be generated from operations, will be sufficient to provide short-term and foreseeable long-term liquidity and meet our expected capital expenditure requirements.

Certain Insurance Matters

As of June 30, 2019 and December 31, 2018, we utilized approximately $108.9 million of letters of credit obtained under our 2016 Revolving Credit Facility as collateral for our insurance obligations.

New Accounting Pronouncements

We review new accounting standards to determine the expected financial impact, if any, that the adoption of such standards will have. See Note 2 - New Accounting Pronouncements of the notes to consolidated financial statements included in Item 1. Financial Statements for further information regarding new accounting standards, including the anticipated dates of adoption and the effects on our consolidated financial position, results of operations or liquidity.

Application of Critical Accounting Policies

Our consolidated financial statements are based on the application of significant accounting policies, which require management to make significant estimates and assumptions. Our significant accounting policies are described in Note 2 – Summary of Significant Accounting Policies of the notes to consolidated financial statements included in Item 8 of our annual report on Form 10-K for the year ended December 31, 2018. We believe that some of the more critical judgment areas in the application of accounting policies that affect our financial condition and results of operations are the impact of changes in the estimates and judgments pertaining to: (a) revenue recognition from contracts with customers; (b) collectibility or valuation of accounts receivable; (c) insurance liabilities; (d) income taxes; and (e) goodwill and identifiable intangible assets.

Revenue Recognition from Contracts with Customers

We believe our most critical accounting policy is revenue recognition in accordance with Accounting Standards Codification Topic 606, “Revenue from Contracts with Customers” (“ASC 606”). In accordance with ASC 606, the Company recognizes revenue by applying the following five step model: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to performance obligations in the contract, and (5) recognize revenue as performance obligations are satisfied.

The Company recognizes revenue at the time the related performance obligation is satisfied by transferring a promised good or service to its customers. A good or service is considered to be transferred when the customer obtains control. The Company can transfer control of a good or service and satisfy its performance obligations either over time or at a point in time. The Company transfers control of a good or service over time and, therefore, satisfies a performance obligation and recognizes revenue over time if one of the following three criteria are met: (a) the customer simultaneously receives and consumes the benefits provided by the Company’s performance as we perform, (b) the Company’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced, or (c) the Company’s performance does not create an asset with an alternative use to us, and we have an enforceable right to payment for performance completed to date.

For our performance obligations satisfied over time, we recognize revenue by measuring the progress toward complete satisfaction of that performance obligation. The selection of the method to measure progress towards completion can be either an input method or an output method and requires judgment based on the nature of the goods or services to be provided.

38

For our construction contracts, revenue is generally recognized over time as our performance creates or enhances an asset that the customer controls as it is created or enhanced. Our fixed price construction projects generally use a cost-to-cost input method to measure our progress towards complete satisfaction of the performance obligation as we believe it best depicts the transfer of control to the customer which occurs as we incur costs on our contracts. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. For our unit price construction contracts, progress towards complete satisfaction is measured through an output method, such as the amount of units produced or delivered, when our performance does not produce significant amounts of work in process or finished goods prior to complete satisfaction of such performance obligations.

For our services contracts, revenue is also generally recognized over time as the customer simultaneously receives and consumes the benefits of our performance as we perform the service. For our fixed price service contracts with specified service periods, revenue is generally recognized on a straight-line basis over such service period when our inputs are expended evenly, and the customer receives and consumes the benefits of our performance throughout the contract term.

The timing of revenue recognition for the manufacturing of new build heat exchangers within our United States industrial services segment depends on the payment terms of the contract, as our performance does not create an asset with an alternative use to us. For those contracts for which we have a right to payment for performance completed to date at all times throughout our performance, inclusive of a cancellation, we recognize revenue over time. For these performance obligations, we use a cost-to-cost input method to measure our progress towards complete satisfaction of the performance obligation as we believe it best depicts the transfer of control to the customer which occurs as we incur costs on our contracts. However, for those contracts for which we do not have a right, at all times, to payment for performance completed to date, we recognize revenue at the point in time when control is transferred to the customer. For bill-and-hold arrangements, revenue is recognized when the customer obtains control of the heat exchanger, which may be prior to shipping, if certain recognition criteria are met.

For certain of our revenue streams, such as call-out repair and service work, outage services, refinery turnarounds and specialty welding services that are performed under time and materials contracts, our progress towards complete satisfaction of such performance obligations is measured using an output method as the customer receives and consumes the benefits of our performance completed to date.

Due to uncertainties inherent in the estimation process, it is possible that estimates of costs to complete a performance obligation will be revised in the near-term. For those performance obligations for which revenue is recognized using a cost-to-cost input method, changes in total estimated costs, and related progress towards complete satisfaction of the performance obligation, are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made. When the current estimate of total costs for a performance obligation indicate a loss, a provision for the entire estimated loss on the unsatisfied performance obligation is made in the period in which the loss becomes evident. For the three and six months ended June 30, 2019 and 2018, there were no changes in total estimated costs that had a significant impact on our operating results. In addition, for the three and six months ended June 30, 2019 and 2018, there were no significant losses recognized.

The timing of revenue recognition may differ from the timing of invoicing to customers. Contract assets include unbilled amounts from our long-term construction projects when revenues recognized under the cost-to-cost measure of progress exceed the amounts invoiced to our customers, as the amounts cannot be billed under the terms of our contracts. Such amounts are recoverable from our customers based upon various measures of performance, including achievement of certain milestones, completion of specified units or completion of a contract. In addition, many of our time and materials arrangements, as well as our contracts to perform turnaround services within the United States industrial services segment, are billed in arrears pursuant to contract terms that are standard within the industry, resulting in contract assets and/or unbilled receivables being recorded, as revenue is recognized in advance of billings. Also included in contract assets are amounts we seek or will seek to collect from customers or others for errors or changes in contract specifications or design, contract change orders or modifications in dispute or unapproved as to scope and/or price, or other customer-related causes of unanticipated additional contract costs (claims and unapproved change orders). Our contract assets do not include capitalized costs to obtain and fulfill a contract. Contract assets are generally classified as current within the Consolidated Balance Sheets.

Contract liabilities from our long-term construction contracts arise when amounts invoiced to our customers exceed revenues recognized under the cost-to-cost measure of progress. Contract liabilities additionally include advanced payments from our customers on certain contracts. Contract liabilities decrease as we recognize revenue from the satisfaction of the related performance obligation and are recorded as either current or long-term, depending upon when we expect to recognize such revenue. The long-term portion of contract liabilities is included in “Other long-term obligations” in the Consolidated Balance Sheets.

See Note 3 - Revenue from Contracts with Customers of the notes to consolidated financial statements included in Item 1. Financial Statements for further disclosure regarding revenue recognition.

Accounts Receivable

Accounts receivable are recognized in the period we deliver goods or provide services to our customers or when our right to consideration is unconditional. We are required to estimate the collectibility of accounts receivable. A considerable amount of judgment is required in assessing the likelihood of realization of receivables. Relevant assessment factors include the creditworthiness of the customer, our prior collection history with the customer and related aging of the past due balances. At June 30, 2019 and December 31, 2018, our accounts receivable of $1,946.8 million and $1,773.6 million, respectively, were recorded net of allowances for doubtful accounts of $15.3 million and $15.4 million, respectively. Specific accounts receivable are evaluated when we believe a customer may not be able to meet its financial obligations due to the deterioration of its financial condition or its credit ratings. The allowance for doubtful accounts requirements are based on the best facts available and are re-evaluated and adjusted on a regular basis as additional information is received.

Insurance Liabilities

We have loss payment deductibles for certain workers’ compensation, automobile liability, general liability and property claims, have self-insured retentions for certain other casualty claims and are self-insured for employee-related healthcare claims. In addition, we maintain a wholly-owned captive insurance subsidiary to manage certain of our insurance liabilities. Losses are recorded based upon estimates of our liability for claims incurred and for claims incurred but not reported. The liabilities are derived from known facts, historical trends and industry averages utilizing the assistance of an actuary to determine the best estimate for the majority of these obligations. We believe the liabilities recognized on the Consolidated Balance Sheets for these obligations are adequate. However, such obligations are difficult to assess and estimate due to numerous factors, including severity of injury, determination of liability in proportion to other parties, timely reporting of occurrences and effectiveness of safety and risk management programs. Therefore, if our actual experience differs from the assumptions and estimates used for recording the liabilities, adjustments may be required and will be recorded in the period that the experience becomes known. Our estimated net insurance liabilities for workers’ compensation, automobile liability, general liability and property claims increased by $7.2 million at June 30, 2019 compared to December 31, 2018, partially as a result of higher revenues, including the impact of acquired companies. If our estimated insurance liabilities for workers’ compensation, automobile liability, general liability and property claims were to increase by 10%, it would have resulted in $16.9 million of additional expense for the six months ended June 30, 2019.

Income Taxes    

We had net deferred income tax liabilities at June 30, 2019 and December 31, 2018 of $70.2 million and $70.8 million, respectively, primarily resulting from differences between the carrying value and income tax basis of certain identifiable intangible assets and depreciable fixed assets, which will impact our taxable income in future periods. Included within these net deferred income tax liabilities are $103.4 million and $104.1 million of deferred income tax assets as of June 30, 2019 and December 31, 2018, respectively. A valuation allowance is required when it is more likely than not that all or a portion of a deferred income tax asset will not be realized. As of June 30, 2019 and December 31, 2018, the total valuation allowance on deferred income tax assets, primarily related to state net operating loss carryforwards, was approximately $3.9 million.

Goodwill and Identifiable Intangible Assets

As of June 30, 2019, we had $1,013.8 million and $488.0 million, respectively, of goodwill and net identifiable intangible assets (primarily consisting of our contract backlog, developed technology/vendor network, customer relationships, non-competition agreements and trade names), arising out of the acquisition of companies. As of December 31, 2018, goodwill and net identifiable intangible assets were $990.9 million and $488.3 million, respectively. As of June 30, 2019, approximately 14.0% of our goodwill related to our United States electrical construction and facilities services segment, approximately 24.7% related to our United States mechanical construction and facilities services segment, approximately 28.4% related to our United States building services segment, and approximately 32.9% related to our United States industrial services segment. The changes to goodwill since December 31, 2018 were related to three acquisitions in 2019 and a purchase price adjustment related to an acquisition completed in 2018. The determination of related estimated useful lives for identifiable intangible assets and whether those assets are impaired involves significant judgments based upon short and long-term projections of future performance. These forecasts reflect assumptions regarding the ability to successfully integrate acquired companies, as well as macroeconomic conditions. ASC Topic 350, “Intangibles – Goodwill and Other” (“ASC 350”) requires that goodwill and other identifiable intangible assets with indefinite useful lives not be amortized, but instead tested at least annually for impairment (which we test each October 1, absent any impairment indicators), and be written down if impaired. ASC 350 requires that goodwill be allocated to its respective reporting unit and that identifiable intangible assets with finite lives be amortized over their useful lives.

We test for impairment of our goodwill at the reporting unit level. Our reporting units are consistent with the reportable segments identified in Note 15, “Segment Information”, of the notes to consolidated financial statements. In assessing whether our goodwill is impaired, we compare the fair value of the reporting unit to the carrying amount, including goodwill. If the fair

40

value exceeds the carrying amount, no impairment loss is recognized. However, if the carrying amount of the reporting unit exceeds the fair value, the goodwill of the reporting unit is impaired and an impairment loss in the amount of the excess is recognized and charged to operations. The fair value of each of our reporting units is generally determined using discounted estimated future cash flows; however, in certain circumstances, consideration is given to a market approach whereby fair value is measured based on a multiple of earnings.

As of the date of our latest impairment test (October 1, 2018), the carrying values of our United States electrical construction and facilities services segment, our United States mechanical construction and facilities services segment, our United States building services segment and our United States industrial services segment were approximately $251.2 million, $398.8 million, $499.5 million and $657.5 million, respectively. The fair values of our United States electrical construction and facilities services segment, our United States mechanical construction and facilities services segment, our United States building services segment and our United States industrial services segment exceeded their carrying values by approximately $1,203.0 million, $1,710.9 million, $628.2 million and $81.2 million, respectively. No impairment of our goodwill was recognized during the three and six months ended June 30, 2019 and 2018.

The weighted average cost of capital used in our annual testing for impairment as of October 1, 2018 was 9.8%, 9.7% and 10.5% for our domestic construction segments, our United States building services segment and our United States industrial services segment, respectively. The perpetual growth rate used for our annual testing was 2.7% for all of our domestic segments. Unfavorable changes in these key assumptions may affect future testing results. For example, keeping all other assumptions constant, a 50 basis point increase in the weighted average costs of capital would cause the estimated fair values of our United States electrical construction and facilities services segment, our United States mechanical construction and facilities services segment, our United States building services segment and our United States industrial services segment to decrease by approximately $91.7 million, $132.4 million, $71.2 million, and $46.4 million, respectively. In addition, keeping all other assumptions constant, a 50 basis point reduction in the perpetual growth rate would cause the estimated fair values of our United States electrical construction and facilities services segment, our United States mechanical construction and facilities services segment, our United States building services segment, and our United States industrial services segment to decrease by approximately $52.5 million, $74.1 million, $38.3 million, and $23.3 million, respectively.

We also test for the impairment of trade names that are not subject to amortization by calculating the fair value using the “relief from royalty payments” methodology. This approach involves two steps: (a) estimating reasonable royalty rates for each trade name and (b) applying these royalty rates to a net revenue stream and discounting the resulting cash flows to determine fair value. This fair value is then compared with the carrying value of each trade name. If the carrying amount of the trade name is greater than the implied fair value of the trade name, an impairment in the amount of the excess is recognized and charged to operations. No impairment of our indefinite-lived trade names was recognized during the three and six months ended June 30, 2019 and 2018.

In addition, we review for the impairment of other identifiable intangible assets that are being amortized whenever facts and circumstances indicate that their carrying values may not be fully recoverable. This test compares their carrying values to the undiscounted pre-tax cash flows expected to result from the use of the assets. If the assets are impaired, the assets are written down to their fair values, generally determined based on their future discounted cash flows. During the three and six months ended June 30, 2018, we recorded a $0.9 million non-cash impairment charge associated with a finite-lived trade name within our United States industrial services segment. No additional impairment of our other identifiable intangible assets was recognized during the three and six months ended June 30, 2019 and 2018.

We have certain businesses, particularly within our United States industrial services segment, whose results are highly impacted by the demand for some of our offerings within the industrial and oil and gas markets. Future performance of this segment, along with a continued evaluation of the conditions of its end user markets, will be important to ongoing impairment assessments. Should this segment’s actual results suffer a decline or expected future results be revised downward, the risk of goodwill impairment or impairment of other identifiable intangible assets would increase.

Our development of the present value of future cash flow projections used in impairment testing is based upon assumptions and estimates by management from a review of our operating results, business plans, anticipated growth rates and margins, and weighted average cost of capital, among other considerations. Those assumptions and estimates can change in future periods, and other factors used in assessing fair value are outside the control of management, such as interest rates. There can be no assurance that estimates and assumptions made for purposes of our goodwill and identifiable intangible asset impairment testing will prove to be accurate predictions of the future. If our assumptions regarding future business performance or anticipated growth rates and/or margins are not achieved, or there is a rise in interest rates, we may be required to record goodwill and/or identifiable intangible asset impairment charges in future periods.

It is not possible at this time to determine if any future impairment charge will result or, if it does, whether such a charge would be material.

ITEM 3.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

We did not use any derivative financial instruments during the six months ended June 30, 2019, including trading or speculating on changes in interest rates or commodity prices of materials used in our business.

We are exposed to market risk for changes in interest rates for borrowings under the 2016 Credit Agreement, which provides for a revolving credit facility and a term loan. Borrowings under the 2016 Credit Agreement bear interest at variable rates. As of June 30, 2019, there were borrowings of $25.0 million outstanding under the 2016 Revolving Credit Facility and the balance of the 2016 Term Loan was $262.0 million. This instrument bears interest at (1) a base rate plus a margin of 0.00% to 0.75%, based on certain financial tests, or (2) United States dollar LIBOR (2.40% at June 30, 2019) plus 1.00% to 1.75%, based on certain financial tests. The base rate is determined by the greater of (a) the prime commercial lending rate announced by Bank of Montreal from time to time (5.50% at June 30, 2019), (b) the federal funds effective rate, plus ½ of 1.00%, (c) the daily one month LIBOR rate, plus 1.00%, or (d) 0.00%. The interest rate in effect at June 30, 2019 was 3.40%. Fees for letters of credit issued under the 2016 Revolving Credit Facility range from 1.00% to 1.75% of the respective face amounts of outstanding letters of credit and are computed based on certain financial tests. Based on the $287.0 million borrowings outstanding under the 2016 Credit Agreement, if overall interest rates were to increase by 100 basis points, interest expense, net of income taxes, would increase by approximately $2.1 million in the next twelve months. Conversely, if overall interest rates were to decrease by 100 basis points, interest expense, net of income taxes, would decrease by approximately $2.1 million in the next twelve months. The 2016 Credit Agreement expires on August 3, 2021. There is no guarantee that we will be able to renew the 2016 Credit Agreement at its expiration.

It is expected that a number of banks currently reporting information used to set LIBOR will stop doing so after 2021, which could either cause LIBOR to stop publication or cause LIBOR to no longer be representative of the underlying market. We believe our exposure to market risk associated with the discontinuation of LIBOR is limited as our 2016 Credit Agreement expires prior to the end of 2021 and given that we are not exposed to any other material contracts that reference LIBOR.

We are exposed to construction market risk and its potential related impact on accounts receivable or contract assets on uncompleted contracts. The amounts recorded may be at risk if our customers’ ability to pay these obligations is negatively impacted by economic conditions. We continually monitor the creditworthiness of our customers and maintain on-going discussions with customers regarding contract status with respect to change orders and billing terms. Therefore, we believe we take appropriate action to manage market and other risks, but there is no assurance that we will be able to reasonably identify all risks with respect to the collectibility of these assets. See also the previous discussions of Revenue Recognition from Contracts with Customers and Accounts Receivable under the heading, “Application of Critical Accounting Policies” in Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Amounts invested in our foreign operations are translated into U.S. dollars at the exchange rates in effect at the end of the period. The resulting translation adjustments are recorded as accumulated other comprehensive (loss) income, a component of equity, in the Consolidated Balance Sheets. We believe the exposure to the effects that fluctuating foreign currencies may have on our consolidated results of operations is limited because our foreign operations primarily invoice customers and collect obligations in their respective local currencies. Additionally, expenses associated with these transactions are generally contracted and paid for in their same local currencies.

In addition, we are exposed to market risk of fluctuations in certain commodity prices of materials, such as copper and steel, which are used as components of supplies or materials utilized in our construction, building services and industrial services operations. We are also exposed to increases in energy prices, particularly as they relate to gasoline prices for our fleet of approximately 11,000 vehicles. While we believe we can increase our contract prices to adjust for some price increases in commodities, there can be no assurance that such price increases, if they were to occur, would be recoverable. Additionally, our fixed price contracts do not allow us to adjust our prices and, as a result, increases in material costs could reduce our profitability with respect to projects in progress.

ITEM 4.   CONTROLS AND PROCEDURES.

Based on an evaluation of our disclosure controls and procedures (as required by Rule 13a-15(b) of the Securities Exchange Act of 1934), our Chairman, President and Chief Executive Officer, Anthony J. Guzzi, and our Executive Vice President and Chief Financial Officer, Mark A. Pompa, have concluded that our disclosure controls and procedures (as defined in Rule 13a-15(e) of the Securities Exchanges Act of 1934) are effective as of the end of the period covered by this report.

There have not been any changes in the Company’s internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934) during the fiscal quarter ended June 30, 2019 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Basis Of Presentation

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with instructions to the Quarterly Report on Form 10-Q and Rule 10-01 of Regulation S-X. Consequently, certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted. References to the “Company,” “EMCOR,” “we,” “us,” “our” and similar words refer to EMCOR Group, Inc. and its consolidated subsidiaries unless the context indicates otherwise. Readers of this report should refer to the consolidated financial statements and the notes thereto included in our latest Annual Report on Form 10-K filed with the Securities and Exchange Commission.

In our opinion, the accompanying unaudited consolidated financial statements contain all adjustments (consisting only of those of a normal recurring nature) necessary to present fairly our financial position and the results of our operations. Our reportable segments reflect certain reclassifications of prior year amounts from our United States mechanical construction and facilities services segment to our United States industrial services segment due to changes in our internal reporting structure.

The results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of the results to be expected for the year ending December 31, 2019.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

New Accounting Pronouncements

New Accounting Pronouncements

On January 1, 2019, we adopted the accounting pronouncement issued by the Financial Accounting Standards Board (“FASB”) to replace existing lease accounting guidance. This pronouncement is intended to provide enhanced transparency and comparability by requiring lessees to record right-of-use assets and corresponding lease liabilities on the balance sheet for most leases. Expenses associated with leases continue to be recognized in a manner similar to previous accounting guidance. We adopted this pronouncement utilizing the transition practical expedient added by the FASB, which eliminated the requirement that entities apply the new lease standard to the comparative periods presented in the year of adoption. The adoption of this accounting pronouncement resulted in the recognition of operating lease right-of-use assets and associated lease liabilities on our balance sheet of $220.2 million and $227.1 million, respectively, as of January 1, 2019. Additional required disclosures have been included within Note 14 - Leases of the notes to consolidated financial statements. Such adoption did not have an impact on our liquidity, results of operations or our compliance with the various covenants contained within our 2016 Credit Agreement as described in further detail within Note 8 - Debt of the notes to consolidated financial statements.

On January 1, 2019, we adopted the accounting pronouncement issued by the FASB related to the reporting of certain items in accumulated other comprehensive income (loss) (“AOCI”). This guidance provides entities the option to reclassify to retained earnings certain tax effects stranded in AOCI as a result of tax reform. As part of our adoption of this accounting pronouncement, we elected not to reclassify the stranded tax effects related to the retirement plans of our United States subsidiaries as such amounts are immaterial. Tax effects remaining in AOCI will be released upon liquidation of each individual retirement plan.

In June 2016, an accounting pronouncement was issued by the FASB which changes the way in which entities estimate and present credit losses for most financial assets, including accounts receivable. This pronouncement is effective for annual and interim periods beginning after December 15, 2019, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this accounting pronouncement will have on its financial position and/or results of operations.

Revenue from Contracts with Customers

6 Months Ended

Revenue from Contract with Customer [Abstract]

Revenue from Contracts with Customers

Revenue from Contracts with Customers

The Company recognizes revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services by applying the following five step model:

(1) Identify the contract with a customer

A contract with a customer exists when: (a) the parties have approved the contract and are committed to perform their respective obligations, (b) the rights of the parties can be identified, (c) payment terms can be identified, (d) the arrangement has commercial substance, and (e) collectibility of consideration is probable. Judgment is required when determining if the contractual criteria are met, specifically in the earlier stages of a project when a formally executed contract may not yet exist. In these situations, the Company evaluates all relevant facts and circumstances, including the existence of other forms of documentation or historical experience with our customers that may indicate a contractual agreement is in place and revenue should be recognized. In determining if the collectibility of consideration is probable, the Company considers the customer’s ability and intention to pay

such consideration through an evaluation of several factors, including an assessment of the creditworthiness of the customer and our prior collection history with such customer.

(2) Identify the performance obligations in the contract

At contract inception, the Company assesses the goods or services promised in a contract and identifies, as a separate performance obligation, each distinct promise to transfer goods or services to the customer. The identified performance obligations represent the “unit of account” for purposes of determining revenue recognition. In order to properly identify separate performance obligations, the Company applies judgment in determining whether each good or service provided is: (a) capable of being distinct, whereby the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer, and (b) distinct within the context of the contract, whereby the transfer of the good or service to the customer is separately identifiable from other promises in the contract.

In addition, when assessing performance obligations within a contract, the Company considers the warranty provisions included within such contract. To the extent the warranty terms provide the customer with an additional service, other than assurance that the promised good or service complies with agreed upon specifications, such warranty is accounted for as a separate performance obligation. In determining whether a warranty provides an additional service, the Company considers each warranty provision in comparison to warranty terms which are standard in the industry.

Our contracts are often modified through change orders to account for changes in the scope and price of the goods or services we are providing. Although the Company evaluates each change order to determine whether such modification creates a separate performance obligation, the majority of our change orders are for goods or services that are not distinct within the context of our original contract and, therefore, are not treated as separate performance obligations.

(3) Determine the transaction price

The transaction price represents the amount of consideration to which the Company expects to be entitled in exchange for transferring promised goods or services to our customers. The consideration promised within a contract may include fixed amounts, variable amounts, or both. To the extent the performance obligation includes variable consideration, including contract bonuses and penalties that can either increase or decrease the transaction price, the Company estimates the amount of variable consideration to be included in the transaction price utilizing one of two prescribed methods, depending on which method better predicts the amount of consideration to which the entity will be entitled. Such methods include: (a) the expected value method, whereby the amount of variable consideration to be recognized represents the sum of probability weighted amounts in a range of possible consideration amounts, and (b) the most likely amount method, whereby the amount of variable consideration to be recognized represents the single most likely amount in a range of possible consideration amounts. When applying these methods, the Company considers all information that is reasonably available, including historical, current and estimates of future performance. The expected value method is typically utilized in situations where a contract contains a large number of possible outcomes while the most likely amount method is typically utilized in situations where a contract has only two possible outcomes.

Variable consideration is included in the transaction price only to the extent it is probable, in the Company’s judgment, that a significant future reversal in the amount of cumulative revenue recognized under the contract will not occur when the uncertainty associated with the variable consideration is subsequently resolved. This threshold is referred to as the variable consideration constraint. In assessing whether to apply the variable consideration constraint, the Company considers if factors exist that could increase the likelihood or the magnitude of a potential reversal of revenue, including, but not limited to, whether: (a) the amount of consideration is highly susceptible to factors outside of the Company’s influence, such as the actions of third parties, (b) the uncertainty surrounding the amount of consideration is not expected to be resolved for a long period of time, (c) the Company’s experience with similar types of contracts is limited or that experience has limited predictive value, (d) the Company has a practice of either offering a broad range of price concessions or changing the payment terms and conditions of similar contracts in similar circumstances, and (e) the contract has a large number and broad range of possible consideration amounts.

Pending change orders represent one of the most common forms of variable consideration included within contract value and typically represent contract modifications for which a change in scope has been authorized or acknowledged by our customer, but the final adjustment to contract price is yet to be negotiated. In estimating the transaction price for pending change orders, the Company considers all relevant facts, including documented correspondence with the customer regarding acknowledgment of and/or agreement with the modification, as well as historical experience with the customer or similar contractual circumstances.

Based upon this assessment, the Company estimates the transaction price, including whether the variable consideration constraint should be applied.

Contract claims are another form of variable consideration which is common within our industry. Claim amounts represent revenue that has been recognized for contract modifications that are not submitted or are in dispute as to both scope and price. In estimating the transaction price for claims, the Company considers all relevant facts available. However, given the uncertainty surrounding claims, including the potential long-term nature of dispute resolution and the broad range of possible consideration amounts, there is an increased likelihood that any additional contract revenue associated with contract claims is constrained. The resolution of claims involves negotiations and, in certain cases, litigation. In the event litigation costs are incurred by us in connection with claims, such litigation costs are expensed as incurred, although we may seek to recover these costs.

For some transactions, the receipt of consideration does not match the timing of the transfer of goods or services to the customer. For such contracts, the Company evaluates whether this timing difference represents a financing arrangement within the contract. Although rare, if a contract is determined to contain a significant financing component, the Company adjusts the promised amount of consideration for the effects of the time value of money when determining the transaction price of such contract. Although our customers may retain a portion of the contract price until completion of the project and final contract settlement, these retainage amounts are not considered a significant financing component as the intent of the withheld amounts is to provide the customer with assurance that we will complete our obligations under the contract rather than to provide financing to the customer. In addition, although we may be entitled to advanced payments from our customers on certain contracts, these advanced payments generally do not represent a significant financing component as the payments are used to meet working capital demands that can be higher in the early stages of a contract, as well as to protect us from our customer failing to meet its obligations under the contract.

Changes in the estimates of transaction prices are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made. Such changes in estimates can result in the recognition of revenue in a current period for performance obligations which were satisfied or partially satisfied in prior periods. Such changes in estimates may also result in the reversal of previously recognized revenue if the ultimate outcome differs from the Company’s previous estimate. For the three and six months ended June 30, 2019 and 2018, there were no significant amounts of revenue recognized during the period related to performance obligations satisfied in prior periods. In addition, for the three and six months ended June 30, 2019 and 2018, there were no significant reversals of revenue recognized associated with the revision of transaction prices.

(4) Allocate the transaction price to performance obligations in the contract

For contracts that contain multiple performance obligations, the Company allocates the transaction price to each performance obligation based on a relative standalone selling price. The Company determines the standalone selling price based on the price at which the performance obligation would have been sold separately in similar circumstances to similar customers. If the standalone selling price is not observable, the Company estimates the standalone selling price taking into account all available information such as market conditions and internal pricing guidelines. In certain circumstances, the standalone selling price is determined using an expected profit margin on anticipated costs related to the performance obligation.

(5) Recognize revenue as performance obligations are satisfied

The Company recognizes revenue at the time the related performance obligation is satisfied by transferring a promised good or service to its customers. A good or service is considered to be transferred when the customer obtains control. The Company can transfer control of a good or service and satisfy its performance obligations either over time or at a point in time. The Company transfers control of a good or service over time and, therefore, satisfies a performance obligation and recognizes revenue over time if one of the following three criteria are met: (a) the customer simultaneously receives and consumes the benefits provided by the Company’s performance as we perform, (b) the Company’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced, or (c) the Company’s performance does not create an asset with an alternative use to us, and we have an enforceable right to payment for performance completed to date.

For our performance obligations satisfied over time, we recognize revenue by measuring the progress toward complete satisfaction of that performance obligation. The selection of the method to measure progress towards completion can be either an input method or an output method and requires judgment based on the nature of the goods or services to be provided.

For our construction contracts, revenue is generally recognized over time as our performance creates or enhances an asset that the customer controls as it is created or enhanced. Our fixed price construction projects generally use a cost-to-cost input method to measure our progress towards complete satisfaction of the performance obligation as we believe it best depicts the transfer of control to the customer which occurs as we incur costs on our contracts. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. For our unit price construction contracts, progress towards complete satisfaction is measured through an output method, such as the amount of units produced or delivered, when our performance does not produce significant amounts of work in process or finished goods prior to complete satisfaction of such performance obligations.

For our services contracts, revenue is also generally recognized over time as the customer simultaneously receives and consumes the benefits of our performance as we perform the service. For our fixed price service contracts with specified service periods, revenue is generally recognized on a straight-line basis over such service period when our inputs are expended evenly, and the customer receives and consumes the benefits of our performance throughout the contract term.

The timing of revenue recognition for the manufacturing of new build heat exchangers within our United States industrial services segment depends on the payment terms of the contract, as our performance does not create an asset with an alternative use to us. For those contracts for which we have a right to payment for performance completed to date at all times throughout our performance, inclusive of a cancellation, we recognize revenue over time. For these performance obligations, we use a cost-to-cost input method to measure our progress towards complete satisfaction of the performance obligation as we believe it best depicts the transfer of control to the customer which occurs as we incur costs on our contracts. However, for those contracts for which we do not have a right, at all times, to payment for performance completed to date, we recognize revenue at the point in time when control is transferred to the customer. For bill-and-hold arrangements, revenue is recognized when the customer obtains control of the heat exchanger, which may be prior to shipping, if certain recognition criteria are met.

For certain of our revenue streams, such as call-out repair and service work, outage services, refinery turnarounds and specialty welding services that are performed under time and materials contracts, our progress towards complete satisfaction of such performance obligations is measured using an output method as the customer receives and consumes the benefits of our performance completed to date.

Due to uncertainties inherent in the estimation process, it is possible that estimates of costs to complete a performance obligation will be revised in the near-term. For those performance obligations for which revenue is recognized using a cost-to-cost input method, changes in total estimated costs, and related progress towards complete satisfaction of the performance obligation, are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made. When the current estimate of total costs for a performance obligation indicate a loss, a provision for the entire estimated loss on the unsatisfied performance obligation is made in the period in which the loss becomes evident. For the three and six months ended June 30, 2019 and 2018, there were no changes in total estimated costs that had a significant impact on our operating results. In addition, for the three and six months ended June 30, 2019 and 2018, there were no significant losses recognized.

Contract Assets and Contract Liabilities

Accounts receivable are recognized in the period when our right to consideration is unconditional. Accounts receivable are recognized net of an allowance for doubtful accounts. A considerable amount of judgment is required in assessing the likelihood of realization of receivables.

The timing of revenue recognition may differ from the timing of invoicing to customers. Contract assets include unbilled amounts from our long-term construction projects when revenues recognized under the cost-to-cost measure of progress exceed the amounts invoiced to our customers, as the amounts cannot be billed under the terms of our contracts. Such amounts are recoverable from our customers based upon various measures of performance, including achievement of certain milestones, completion of specified units or completion of a contract. In addition, many of our time and materials arrangements, as well as our contracts to perform turnaround services within the United States industrial services segment, are billed in arrears pursuant to contract terms that are standard within the industry, resulting in contract assets and/or unbilled receivables being recorded, as revenue is recognized in advance of billings. Also included in contract assets are amounts we seek or will seek to collect from customers or others for errors or changes in contract specifications or design, contract change orders or modifications in dispute or unapproved as to scope and/or price, or other customer-related causes of unanticipated additional contract costs (claims and unapproved change orders). Our contract assets do not include capitalized costs to obtain and fulfill a contract. Contract assets are generally classified as current within the Consolidated Balance Sheets.

Contract liabilities from our long-term construction contracts arise when amounts invoiced to our customers exceed revenues recognized under the cost-to-cost measure of progress. Contract liabilities additionally include advanced payments from our customers on certain contracts. Contract liabilities decrease as we recognize revenue from the satisfaction of the related performance obligation and are recorded as either current or long-term, depending upon when we expect to recognize such revenue. The long-term portion of contract liabilities is included in “Other long-term obligations” in the Consolidated Balance Sheets.

Net contract liabilities consisted of the following (in thousands):

	June 30, 2019			December 31, 2018
Contract assets, current	$	179,439		$	158,243
Contract assets, non-current	—			—
Contract liabilities, current	(544,346		)	(552,290		)
Contract liabilities, non-current	(2,090		)	(2,069		)
Net contract liabilities	$	(366,997	)	$	(396,116	)

The $29.1 million decrease in net contract liabilities for the six months ended June 30, 2019 was primarily attributable to a decrease in net contract liabilities on our uncompleted long-term construction contracts, partially as a result of the timing of billings to our customers. Contract assets and contract liabilities increased by approximately $5.8 million and $10.5 million, respectively, as a result of acquisitions made by us in 2019. There was no significant impairment of contract assets recognized during either period presented.

Transaction Price Allocated to Remaining Unsatisfied Performance Obligations     

The following table presents the transaction price allocated to remaining unsatisfied performance obligations (“remaining performance obligations”) for each of our reportable segments and their respective percentages of total remaining performance obligations (in thousands, except for percentages):

	June 30, 2019		% of Total
Remaining performance obligations:
United States electrical construction and facilities services	$	1,175,333	28	%
United States mechanical construction and facilities services	2,290,438		54	%
United States building services	545,776		13	%
United States industrial services	89,247		2	%
Total United States operations	4,100,794		97	%
United Kingdom building services	125,201		3	%
Total worldwide operations	$	4,225,995	100	%

Our remaining performance obligations at June 30, 2019 were $4.23 billion. Remaining performance obligations increase with awards of new contracts and decrease as we perform work and recognize revenue on existing contracts. We include a project within our remaining performance obligations at such time the project is awarded and agreement on contract terms has been reached. Our remaining performance obligations include amounts related to contracts for which a fixed price contract value is not assigned when a reasonable estimate of total transaction price can be made.

Remaining performance obligations include unrecognized revenues to be realized from uncompleted construction contracts. Although many of our construction contracts are subject to cancellation at the election of our customers, in accordance with industry practice, we do not limit the amount of unrecognized revenue included within remaining performance obligations due to the inherent substantial economic penalty that would be incurred by our customers upon cancellation. We believe our reported remaining performance obligations for our construction contracts are firm and contract cancellations have not had a material adverse effect on us.

Remaining performance obligations also include unrecognized revenues expected to be realized over the remaining term of service contracts. However, to the extent a service contract includes a cancellation clause which allows for the termination of such contract by either party without a substantive penalty, the remaining contract term, and therefore, the amount of unrecognized revenues included within remaining performance obligations, is limited to the notice period required for the termination.

Our remaining performance obligations are comprised of: (a) original contract amounts, (b) change orders for which we have received written confirmations from our customers, (c) pending change orders for which we expect to receive confirmations in the ordinary course of business, (d) claim amounts that we have made against customers for which we have determined we have a legal basis under existing contractual arrangements and as to which the variable consideration constraint does not apply, and (e) other forms of variable consideration to the extent that such variable consideration has been included within the transaction price of our contracts. Such claim and other variable consideration amounts were immaterial for all periods presented.

Refer to the table below for additional information regarding our remaining performance obligations, including an estimate of when we expect to recognize such remaining performance obligations as revenue (in thousands):

Acquisitions Of Businesses

Acquisitions of Businesses     

Acquisitions are accounted for utilizing the acquisition method of accounting and the prices paid for them are allocated to their respective assets and liabilities based on the estimated fair value of such assets and liabilities at the dates of their respective acquisition by us.

During the first half of 2019, we acquired three companies for a total consideration of $64.4 million. In January 2019, we acquired a company which provides mobile mechanical services within the Southern region of the United States. In April 2019, we acquired a company which provides electrical contracting services in central Iowa. In May 2019, we acquired a company which provides building automation and controls solutions within the Western region of the United States. The results of operations for the companies acquired in January and May have been included within our United States building services segment. The results of operations for the company acquired in April have been included within our United States electrical construction and facilities services segment. In connection with these acquisitions, we acquired working capital of $18.5 million and other net assets of $0.2 million and have preliminarily ascribed $22.8 million to goodwill and $22.9 million to identifiable intangible assets.

During calendar year 2018, we acquired four companies for a total consideration of $71.6 million. Two companies provide mobile mechanical services, one within the Eastern region and the other within the Western region of the United States. The third company is a full service provider of mechanical services within the Southern region of the United States. The results of these three companies have been included in our United States building services segment. The fourth company provides electrical construction and maintenance services for industrial and commercial buildings in North Texas, and its results have been included in our United States electrical construction and facilities services segment. In connection with these acquisitions, we acquired working capital of $8.9 million and have preliminarily ascribed $26.1 million to goodwill and $36.6 million to identifiable intangible assets.

We expect that all of the goodwill acquired in connection with these acquisitions will be deductible for tax purposes. The purchase price allocations for the businesses acquired in 2019 and two of the businesses acquired in 2018 are preliminary and subject to change during their respective measurement periods. The purchase price allocations for the remaining two businesses acquired in 2018 have been finalized with an insignificant impact.

Disposition of Assets

Disposition of Assets    

Due to a historical pattern of losses in the construction operations of our United Kingdom segment and our negative assessment of construction market conditions in the United Kingdom for the foreseeable future, we ceased construction operations in the United Kingdom during the third quarter of 2014. The results of the construction operations of our United Kingdom segment for all periods are presented in the consolidated financial statements as discontinued operations.

No income or expense was recognized from the discontinued operation for the three and six months ended June 30, 2019.

The results of discontinued operations for the three and six months ended June 30, 2018 were as follows (in thousands):

	For the three months ended June 30, 2018			For the six months ended June 30, 2018

Loss from discontinued operation, net of income taxes	$	(205	)	$	(487	)
Diluted loss per share from discontinued operation	$	(0.00	)	$	(0.01	)

The loss from discontinued operations in 2018 was primarily due to legal costs related to the settlement of final contract balances on certain construction projects completed in prior years.

Included in the Consolidated Balance Sheet at December 31, 2018 were approximately $3.7 million of current liabilities associated with the discontinued operation, primarily consisting of contract retentions, contract warranty obligations and other accrued expenses. No significant liabilities remain as of June 30, 2019.

Credit Agreement        

We have a credit agreement dated as of August 3, 2016, which provides for a $900.0 million revolving credit facility (the “2016 Revolving Credit Facility”) and a $400.0 million term loan (the “2016 Term Loan”) (collectively referred to as the “2016 Credit Agreement”) expiring August 3, 2021. We may increase the 2016 Revolving Credit Facility to $1.3 billion if additional lenders are identified and/or existing lenders are willing to increase their current commitments. We may allocate up to $300.0 million of available capacity under the 2016 Revolving Credit Facility to letters of credit for our account or for the account of any of our subsidiaries. Obligations under the 2016 Credit Agreement are guaranteed by most of our direct and indirect subsidiaries and are secured by substantially all of our assets. The 2016 Credit Agreement contains various covenants providing for, among other things, maintenance of certain financial ratios and certain limitations on payment of dividends, common stock repurchases, investments, acquisitions, indebtedness and capital expenditures. We were in compliance with all such covenants as of June 30, 2019 and December 31, 2018. A commitment fee is payable on the average daily unused amount of the 2016 Revolving Credit Facility, which ranges from 0.15% to 0.30%, based on certain financial tests. The fee was 0.15% of the unused amount as of June 30, 2019. Borrowings under the 2016 Credit Agreement bear interest at (1) a base rate plus a margin of 0.00% to 0.75%, based on certain financial tests, or (2) United States dollar LIBOR (2.40% at June 30, 2019) plus 1.00% to 1.75%, based on certain financial tests. The base rate is determined by the greater of (a) the prime commercial lending rate announced by Bank of Montreal from time to time (5.50% at June 30, 2019), (b) the federal funds effective rate, plus ½ of 1.00%, (c) the daily one month LIBOR rate, plus 1.00%, or (d) 0.00%. The interest rate in effect at June 30, 2019 was 3.40%. Fees for letters of credit issued under the 2016 Revolving Credit Facility range from 1.00% to 1.75% of the respective face amounts of outstanding letters of credit and are computed based on certain financial tests. Debt issuance costs are amortized over the life of the agreement and are included as part of interest expense. The 2016 Term Loan previously required us to make principal payments of $5.0 million on the last day of March, June, September and December of each year, which commenced with the calendar quarter ended December 31, 2016. On December 30, 2016, we made a payment of $100.0 million, of which $5.0 million represented our required quarterly payment and $95.0 million represented a prepayment of outstanding principal. Such prepayment was applied against the remaining mandatory quarterly payments on a ratable basis. As a result, commencing with the calendar quarter ended March 31, 2017, our required quarterly payment has been reduced to $3.8 million. All unpaid principal and interest is due on August 3, 2021. As of June 30, 2019 and December 31, 2018, the balance of the 2016 Term Loan was $262.0 million and $269.6 million, respectively. As of June 30, 2019 and December 31, 2018, we had approximately $109.0 million of letters of credit outstanding. There were $25.0 million in borrowings outstanding under the 2016 Revolving Credit Facility as of June 30, 2019 and December 31, 2018.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements        

We use a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy, which gives the highest priority to quoted prices in active markets, is comprised of the following three levels:

Level 1 – Unadjusted quoted market prices in active markets for identical assets and liabilities.

Level 2 – Observable inputs, other than Level 1 inputs. Level 2 inputs would typically include quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly.

Level 3 – Prices or valuations that require inputs that are both significant to the measurement and unobservable.

The following tables provide the assets and liabilities carried at fair value measured on a recurring basis as of June 30, 2019 and December 31, 2018 (in thousands):  

	Assets at Fair Value as of June 30, 2019
Asset Category	Level 1		Level 2		Level 3		Total
Cash and cash equivalents (1)	$	213,374	$	—	$	—	$	213,374
Restricted cash (2)	2,394		—		—		2,394
Deferred compensation plan assets (3)	29,927		—		—		29,927
Total	$	245,695	$	—	$	—	$	245,695

	Assets at Fair Value as of December 31, 2018
Asset Category	Level 1		Level 2		Level 3		Total
Cash and cash equivalents (1)	$	363,907	$	—	$	—	$	363,907
Restricted cash (2)	2,307		—		—		2,307
Deferred compensation plan assets (3)	23,124		—		—		23,124
Total	$	389,338	$	—	$	—	$	389,338

 ________

(1) Cash and cash equivalents include money market funds with original maturity dates of three months or less, which are Level 1 assets. At June 30, 2019 and December 31, 2018, we had $42.4 million and $161.3 million, respectively, in money market funds.

(2) Restricted cash is classified as “Prepaid expenses and other” in the Consolidated Balance Sheets. Restricted cash primarily represents cash held in account for use on customer contracts.

(3) Deferred compensation plan assets are classified as “Other assets” in the Consolidated Balance Sheets.

We believe that the carrying values of our financial instruments, which include accounts receivable and other financing commitments, approximate their fair values due primarily to their short-term maturities and low risk of counterparty default. The carrying value of our debt associated with the 2016 Credit Agreement approximates its fair value due to the variable rate on such debt.

Income Taxes        

In 2018, we finalized our accounting for the income tax effects of the Tax Cuts and Jobs Act (the “Tax Act”). We continue to monitor for potential future changes in certain state and local tax regulations resulting from the Tax Act which may have an impact on our consolidated income tax provision in future periods.

For the three months ended June 30, 2019 and 2018, our income tax provision from continuing operations was $33.2 million and $26.5 million, respectively, based on an effective income tax rate, before discrete items and less amounts attributable to noncontrolling interests, of 28.4% and 27.8%, respectively. The actual income tax rate on income from continuing operations, less amounts attributable to noncontrolling interests, for the three months ended June 30, 2019 and 2018, inclusive of discrete items, was 28.3% and 27.2%, respectively. For the six months ended June 30, 2019 and 2018, our income tax provision from continuing operations was $60.6 million and $47.2 million, respectively, based on an effective income tax rate, before discrete items and less amounts attributable to noncontrolling interests, of 28.2% and 27.7%, respectively. The actual income tax rate on income from continuing operations, less amounts attributable to noncontrolling interests, for the six months ended June 30, 2019 and 2018, inclusive of discrete items, was 27.9% and 27.1%, respectively. The actual income tax rates differed from the statutory tax rate due to state and local income taxes and other permanent book to tax differences. The increase in the 2019 income tax provision was primarily due to increased income from continuing operations. The increase in the actual income tax rate on income from continuing operations for both the three and six months ended June 30, 2019 compared to the three and six months ended

June 30, 2018, was primarily due to the continued application of the Tax Act, including the implementation of interpretative guidance issued throughout 2018 regarding certain permanent differences and other non-deductible expenses.

As of June 30, 2019 and December 31, 2018, we had no unrecognized income tax benefits.

We file income tax returns with the Internal Revenue Service and various state, local and foreign tax agencies. The Company is currently under examination by various taxing authorities for the years 2014 through 2017.

On September 26, 2011, our Board of Directors authorized us to repurchase up to $100.0 million of our outstanding common stock. On December 5, 2013, October 23, 2014, October 28, 2015, October 25, 2017 and October 23, 2018, our Board of Directors authorized us to repurchase up to an additional $100.0 million, $250.0 million, $200.0 million, $100.0 million and $200.0 million of our outstanding common stock, respectively. No shares of our common stock were repurchased during the six months ended June 30, 2019. Since the inception of the repurchase programs through June 30, 2019, we have repurchased approximately 15.9 million shares of our common stock for approximately $791.5 million. As of June 30, 2019, there remained authorization for us to repurchase approximately $158.5 million of our shares. The repurchase programs have no expiration date and do not obligate the Company to acquire any particular amount of common stock and may be suspended, recommenced or discontinued at any time or from time to time without prior notice. We may repurchase our shares from time to time to the extent permitted by securities laws and other legal requirements, including provisions in our 2016 Credit Agreement, placing limitations on such repurchases. The repurchase programs have been and will be funded from our operations.

Retirement Plans

Our United Kingdom subsidiary has a defined benefit pension plan covering all eligible employees (the “UK Plan”); however, no individual joining the company after October 31, 2001 may participate in the UK Plan. On May 31, 2010, we curtailed the future accrual of benefits for active employees under such plan. We also sponsor three domestic retirement plans in which participation by new individuals is frozen.

Government Contracts

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

Legal Proceedings     

We are involved in several legal proceedings in which damages and claims have been asserted against us. We believe that we have a number of valid defenses to such proceedings and claims and intend to vigorously defend ourselves. Other potential claims may exist that have not yet been asserted against us. We do not believe that any such matters will have a material adverse effect on our financial position, results of operations or liquidity. Litigation is subject to many uncertainties and the outcome of litigation is not predictable with assurance. It is possible that some litigation matters for which liabilities have not been recorded could be decided unfavorably to us, and that any such unfavorable decisions could have a material adverse effect on our financial position, results of operations or liquidity.

Restructuring expenses        

Restructuring expenses, relating to employee severance obligations, were $0.2 million and $0.4 million for the three and six months ended June 30, 2019, respectively, and $0.4 million and $0.5 million for the three and six months ended June 30, 2018, respectively. As of June 30, 2019, the balance of restructuring obligations yet to be paid was $0.7 million. Such remaining amounts will be paid pursuant to our contractual obligations throughout 2020 and 2021. No material expenses in connection with restructuring from continuing operations are expected to be incurred during the remainder of 2019.

Leases [Abstract]

Leases

Leases        

On January 1, 2019, we adopted Accounting Standards Codification Topic 842, “Leases” (“ASC 842”). This pronouncement requires lessees to record right-of-use assets and corresponding lease liabilities on the balance sheet for most leases. We adopted this pronouncement utilizing the transition practical expedient which eliminates the requirement that the new lease standard be applied to comparative periods presented in the year of adoption.

As part of our adoption, we elected to utilize the package of practical expedients permitted under the new standard, which allowed us to not reassess: (a) whether an existing contract is or contains a lease, (b) the classification for existing leases and (c) initial direct costs. Further, as permitted by the standard, we made an accounting policy election not to record right-of-use assets or lease liabilities for leases with an initial term of 12 months or less. Instead, consistent with previous accounting guidance, we will recognize payments for such leases in the statement of operations on a straight-line basis over the lease term.

We lease real estate, vehicles and equipment under various operating and finance leases. A lease exists when a contract or part of a contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. In determining whether a lease exists, we consider whether a contract provides us with both: (a) the right to obtain substantially all of the economic benefits from the use of the identified asset and (b) the right to direct the use of the identified asset.

Many of our leases include base rental periods coupled with options to renew or terminate the lease, generally at our discretion. Certain leases additionally include options to purchase the leased asset. In evaluating the lease term, we consider whether we are reasonably certain to exercise such options. To the extent a significant economic incentive exists to exercise an option, that option is included within the lease term. However, based on the nature of our lease arrangements, options generally do not provide us with a significant economic incentive and are therefore excluded from the lease term for the majority of our arrangements.

Our leases typically include a combination of fixed and variable payments. Fixed payments are generally included when measuring the right-of-use asset and lease liability. Variable payments, which primarily represent payments based on usage of the underlying asset, are generally excluded from such measurement and expensed as incurred. In addition, certain of our lease arrangements may contain a lease coupled with an arrangement to provide other services, such as maintenance, or may require us to make other payments on behalf of the lessor related to the leased asset, such as payments for taxes or insurance. As permitted by ASC 842, we have elected to account for these non-lease components together with the associated lease component. This election has been made for each of our asset classes.

The measurement of right-of-use assets and lease liabilities requires us to estimate appropriate discount rates. To the extent the rate implicit in the lease is readily determinable, such rate is utilized. However, based on information available at lease commencement for the majority of our leases, the rate implicit in the lease is not known. In these instances, we utilize an incremental borrowing rate, which represents the rate of interest that we would pay to borrow on a collateralized basis over a similar term.

Our lease arrangements generally do not contain significant restrictions or covenants; however, certain of our vehicle and equipment leases include residual value guarantees, whereby we provide a guarantee to the lessor that the value of the underlying asset will be at least a specified amount at the end of the lease. Amounts probable of being owed under these guarantees are included within the measurement of the right-of-use asset and lease liability.

Revenue from Contracts with Customers (Policies)

6 Months Ended

Jun. 30, 2019

Revenue from Contract with Customer [Abstract]

Revenue Recognition

The Company recognizes revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services by applying the following five step model:

(1) Identify the contract with a customer

A contract with a customer exists when: (a) the parties have approved the contract and are committed to perform their respective obligations, (b) the rights of the parties can be identified, (c) payment terms can be identified, (d) the arrangement has commercial substance, and (e) collectibility of consideration is probable. Judgment is required when determining if the contractual criteria are met, specifically in the earlier stages of a project when a formally executed contract may not yet exist. In these situations, the Company evaluates all relevant facts and circumstances, including the existence of other forms of documentation or historical experience with our customers that may indicate a contractual agreement is in place and revenue should be recognized. In determining if the collectibility of consideration is probable, the Company considers the customer’s ability and intention to pay

such consideration through an evaluation of several factors, including an assessment of the creditworthiness of the customer and our prior collection history with such customer.

(2) Identify the performance obligations in the contract

At contract inception, the Company assesses the goods or services promised in a contract and identifies, as a separate performance obligation, each distinct promise to transfer goods or services to the customer. The identified performance obligations represent the “unit of account” for purposes of determining revenue recognition. In order to properly identify separate performance obligations, the Company applies judgment in determining whether each good or service provided is: (a) capable of being distinct, whereby the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer, and (b) distinct within the context of the contract, whereby the transfer of the good or service to the customer is separately identifiable from other promises in the contract.

In addition, when assessing performance obligations within a contract, the Company considers the warranty provisions included within such contract. To the extent the warranty terms provide the customer with an additional service, other than assurance that the promised good or service complies with agreed upon specifications, such warranty is accounted for as a separate performance obligation. In determining whether a warranty provides an additional service, the Company considers each warranty provision in comparison to warranty terms which are standard in the industry.

Our contracts are often modified through change orders to account for changes in the scope and price of the goods or services we are providing. Although the Company evaluates each change order to determine whether such modification creates a separate performance obligation, the majority of our change orders are for goods or services that are not distinct within the context of our original contract and, therefore, are not treated as separate performance obligations.

(3) Determine the transaction price

The transaction price represents the amount of consideration to which the Company expects to be entitled in exchange for transferring promised goods or services to our customers. The consideration promised within a contract may include fixed amounts, variable amounts, or both. To the extent the performance obligation includes variable consideration, including contract bonuses and penalties that can either increase or decrease the transaction price, the Company estimates the amount of variable consideration to be included in the transaction price utilizing one of two prescribed methods, depending on which method better predicts the amount of consideration to which the entity will be entitled. Such methods include: (a) the expected value method, whereby the amount of variable consideration to be recognized represents the sum of probability weighted amounts in a range of possible consideration amounts, and (b) the most likely amount method, whereby the amount of variable consideration to be recognized represents the single most likely amount in a range of possible consideration amounts. When applying these methods, the Company considers all information that is reasonably available, including historical, current and estimates of future performance. The expected value method is typically utilized in situations where a contract contains a large number of possible outcomes while the most likely amount method is typically utilized in situations where a contract has only two possible outcomes.

Variable consideration is included in the transaction price only to the extent it is probable, in the Company’s judgment, that a significant future reversal in the amount of cumulative revenue recognized under the contract will not occur when the uncertainty associated with the variable consideration is subsequently resolved. This threshold is referred to as the variable consideration constraint. In assessing whether to apply the variable consideration constraint, the Company considers if factors exist that could increase the likelihood or the magnitude of a potential reversal of revenue, including, but not limited to, whether: (a) the amount of consideration is highly susceptible to factors outside of the Company’s influence, such as the actions of third parties, (b) the uncertainty surrounding the amount of consideration is not expected to be resolved for a long period of time, (c) the Company’s experience with similar types of contracts is limited or that experience has limited predictive value, (d) the Company has a practice of either offering a broad range of price concessions or changing the payment terms and conditions of similar contracts in similar circumstances, and (e) the contract has a large number and broad range of possible consideration amounts.

Pending change orders represent one of the most common forms of variable consideration included within contract value and typically represent contract modifications for which a change in scope has been authorized or acknowledged by our customer, but the final adjustment to contract price is yet to be negotiated. In estimating the transaction price for pending change orders, the Company considers all relevant facts, including documented correspondence with the customer regarding acknowledgment of and/or agreement with the modification, as well as historical experience with the customer or similar contractual circumstances.

Based upon this assessment, the Company estimates the transaction price, including whether the variable consideration constraint should be applied.

Contract claims are another form of variable consideration which is common within our industry. Claim amounts represent revenue that has been recognized for contract modifications that are not submitted or are in dispute as to both scope and price. In estimating the transaction price for claims, the Company considers all relevant facts available. However, given the uncertainty surrounding claims, including the potential long-term nature of dispute resolution and the broad range of possible consideration amounts, there is an increased likelihood that any additional contract revenue associated with contract claims is constrained. The resolution of claims involves negotiations and, in certain cases, litigation. In the event litigation costs are incurred by us in connection with claims, such litigation costs are expensed as incurred, although we may seek to recover these costs.

For some transactions, the receipt of consideration does not match the timing of the transfer of goods or services to the customer. For such contracts, the Company evaluates whether this timing difference represents a financing arrangement within the contract. Although rare, if a contract is determined to contain a significant financing component, the Company adjusts the promised amount of consideration for the effects of the time value of money when determining the transaction price of such contract. Although our customers may retain a portion of the contract price until completion of the project and final contract settlement, these retainage amounts are not considered a significant financing component as the intent of the withheld amounts is to provide the customer with assurance that we will complete our obligations under the contract rather than to provide financing to the customer. In addition, although we may be entitled to advanced payments from our customers on certain contracts, these advanced payments generally do not represent a significant financing component as the payments are used to meet working capital demands that can be higher in the early stages of a contract, as well as to protect us from our customer failing to meet its obligations under the contract.

Changes in the estimates of transaction prices are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made. Such changes in estimates can result in the recognition of revenue in a current period for performance obligations which were satisfied or partially satisfied in prior periods. Such changes in estimates may also result in the reversal of previously recognized revenue if the ultimate outcome differs from the Company’s previous estimate. For the three and six months ended June 30, 2019 and 2018, there were no significant amounts of revenue recognized during the period related to performance obligations satisfied in prior periods. In addition, for the three and six months ended June 30, 2019 and 2018, there were no significant reversals of revenue recognized associated with the revision of transaction prices.

(4) Allocate the transaction price to performance obligations in the contract

For contracts that contain multiple performance obligations, the Company allocates the transaction price to each performance obligation based on a relative standalone selling price. The Company determines the standalone selling price based on the price at which the performance obligation would have been sold separately in similar circumstances to similar customers. If the standalone selling price is not observable, the Company estimates the standalone selling price taking into account all available information such as market conditions and internal pricing guidelines. In certain circumstances, the standalone selling price is determined using an expected profit margin on anticipated costs related to the performance obligation.

(5) Recognize revenue as performance obligations are satisfied

The Company recognizes revenue at the time the related performance obligation is satisfied by transferring a promised good or service to its customers. A good or service is considered to be transferred when the customer obtains control. The Company can transfer control of a good or service and satisfy its performance obligations either over time or at a point in time. The Company transfers control of a good or service over time and, therefore, satisfies a performance obligation and recognizes revenue over time if one of the following three criteria are met: (a) the customer simultaneously receives and consumes the benefits provided by the Company’s performance as we perform, (b) the Company’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced, or (c) the Company’s performance does not create an asset with an alternative use to us, and we have an enforceable right to payment for performance completed to date.

For our performance obligations satisfied over time, we recognize revenue by measuring the progress toward complete satisfaction of that performance obligation. The selection of the method to measure progress towards completion can be either an input method or an output method and requires judgment based on the nature of the goods or services to be provided.

For our construction contracts, revenue is generally recognized over time as our performance creates or enhances an asset that the customer controls as it is created or enhanced. Our fixed price construction projects generally use a cost-to-cost input method to measure our progress towards complete satisfaction of the performance obligation as we believe it best depicts the transfer of control to the customer which occurs as we incur costs on our contracts. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. For our unit price construction contracts, progress towards complete satisfaction is measured through an output method, such as the amount of units produced or delivered, when our performance does not produce significant amounts of work in process or finished goods prior to complete satisfaction of such performance obligations.

For our services contracts, revenue is also generally recognized over time as the customer simultaneously receives and consumes the benefits of our performance as we perform the service. For our fixed price service contracts with specified service periods, revenue is generally recognized on a straight-line basis over such service period when our inputs are expended evenly, and the customer receives and consumes the benefits of our performance throughout the contract term.

The timing of revenue recognition for the manufacturing of new build heat exchangers within our United States industrial services segment depends on the payment terms of the contract, as our performance does not create an asset with an alternative use to us. For those contracts for which we have a right to payment for performance completed to date at all times throughout our performance, inclusive of a cancellation, we recognize revenue over time. For these performance obligations, we use a cost-to-cost input method to measure our progress towards complete satisfaction of the performance obligation as we believe it best depicts the transfer of control to the customer which occurs as we incur costs on our contracts. However, for those contracts for which we do not have a right, at all times, to payment for performance completed to date, we recognize revenue at the point in time when control is transferred to the customer. For bill-and-hold arrangements, revenue is recognized when the customer obtains control of the heat exchanger, which may be prior to shipping, if certain recognition criteria are met.

For certain of our revenue streams, such as call-out repair and service work, outage services, refinery turnarounds and specialty welding services that are performed under time and materials contracts, our progress towards complete satisfaction of such performance obligations is measured using an output method as the customer receives and consumes the benefits of our performance completed to date.

Due to uncertainties inherent in the estimation process, it is possible that estimates of costs to complete a performance obligation will be revised in the near-term. For those performance obligations for which revenue is recognized using a cost-to-cost input method, changes in total estimated costs, and related progress towards complete satisfaction of the performance obligation, are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made. When the current estimate of total costs for a performance obligation indicate a loss, a provision for the entire estimated loss on the unsatisfied performance obligation is made in the period in which the loss becomes evident.

Fair Value Disclosures [Abstract]

Fair Value Measurements

We use a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy, which gives the highest priority to quoted prices in active markets, is comprised of the following three levels:

Level 1 – Unadjusted quoted market prices in active markets for identical assets and liabilities.

Level 2 – Observable inputs, other than Level 1 inputs. Level 2 inputs would typically include quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly.

Level 3 – Prices or valuations that require inputs that are both significant to the measurement and unobservable.

Leases (Policies)

Leases [Abstract]

Leases

On January 1, 2019, we adopted Accounting Standards Codification Topic 842, “Leases” (“ASC 842”). This pronouncement requires lessees to record right-of-use assets and corresponding lease liabilities on the balance sheet for most leases. We adopted this pronouncement utilizing the transition practical expedient which eliminates the requirement that the new lease standard be applied to comparative periods presented in the year of adoption.

As part of our adoption, we elected to utilize the package of practical expedients permitted under the new standard, which allowed us to not reassess: (a) whether an existing contract is or contains a lease, (b) the classification for existing leases and (c) initial direct costs. Further, as permitted by the standard, we made an accounting policy election not to record right-of-use assets or lease liabilities for leases with an initial term of 12 months or less. Instead, consistent with previous accounting guidance, we will recognize payments for such leases in the statement of operations on a straight-line basis over the lease term.

We lease real estate, vehicles and equipment under various operating and finance leases. A lease exists when a contract or part of a contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. In determining whether a lease exists, we consider whether a contract provides us with both: (a) the right to obtain substantially all of the economic benefits from the use of the identified asset and (b) the right to direct the use of the identified asset.

Many of our leases include base rental periods coupled with options to renew or terminate the lease, generally at our discretion. Certain leases additionally include options to purchase the leased asset. In evaluating the lease term, we consider whether we are reasonably certain to exercise such options. To the extent a significant economic incentive exists to exercise an option, that option is included within the lease term. However, based on the nature of our lease arrangements, options generally do not provide us with a significant economic incentive and are therefore excluded from the lease term for the majority of our arrangements.

Our leases typically include a combination of fixed and variable payments. Fixed payments are generally included when measuring the right-of-use asset and lease liability. Variable payments, which primarily represent payments based on usage of the underlying asset, are generally excluded from such measurement and expensed as incurred. In addition, certain of our lease arrangements may contain a lease coupled with an arrangement to provide other services, such as maintenance, or may require us to make other payments on behalf of the lessor related to the leased asset, such as payments for taxes or insurance. As permitted by ASC 842, we have elected to account for these non-lease components together with the associated lease component. This election has been made for each of our asset classes.

The measurement of right-of-use assets and lease liabilities requires us to estimate appropriate discount rates. To the extent the rate implicit in the lease is readily determinable, such rate is utilized. However, based on information available at lease commencement for the majority of our leases, the rate implicit in the lease is not known. In these instances, we utilize an incremental borrowing rate, which represents the rate of interest that we would pay to borrow on a collateralized basis over a similar term.

Our lease arrangements generally do not contain significant restrictions or covenants; however, certain of our vehicle and equipment leases include residual value guarantees, whereby we provide a guarantee to the lessor that the value of the underlying asset will be at least a specified amount at the end of the lease. Amounts probable of being owed under these guarantees are included within the measurement of the right-of-use asset and lease liability.
