Significant Accounting Policies

Consolidation

The accompanying Financial Statements include the results of operations of the Company and its subsidiaries. Significant intercompany transactions and balances have been eliminated. Certain reclassifications were made to prior year amounts to conform to the current year presentation.

In connection with the adoption of

Revenue from Contracts with Customers (Topic 606)

, the Company adjusted its presentation of costs and estimated earnings in excess of billings on uncompleted contracts and billings in excess of costs, which impacted both the Company’s consolidated balance sheet as of December 31, 2017 and consolidated statements of cash flows for the years ended December 31, 2017 and 2016. Specifically, costs and estimated earnings in excess of billings became contract assets in the Company’s consolidated balance sheets and $42.7 million of contract retainages previously classified as accounts receivable, net of allowances were reclassified into contract assets as of December 31, 2017. Additionally, billings in excess of costs and estimated earnings on uncompleted contracts became contract liabilities in the Company’s consolidated balance sheets and accruals for contracts in a loss position previously classified in other current liabilities were reclassified into contract liabilities as of December 31, 2017. See Note 3 — Revenue Recognition to the Financial Statements for additional information.

Revenue Recognition

On January 1, 2018, the Company adopted

accounting standards update (“ASU”) No

. 2014-09,

Revenue from Contracts with Customers (Topic

606)

using the modified retrospective method for contracts that were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under this new pronouncement, while prior period amounts were not adjusted and continue to be reported under the accounting standard

Revenue Recognition (Topic

605

), which was in effect for those periods. Differences in revenue recognition under Topic 606 were due to accelerated recognition of contract provisions related to variable consideration previously not permitted to be recognized under Topic 605 until no remaining contingency existed related to this consideration.

Under Topic 606,

the Company recognizes revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for goods or services provided. Revenue associated with contracts with customers is recognized over time as the Company’s performance creates or enhances customer controlled assets or creates or enhances an asset with no alternative use, for which the Company has an enforceable right to receive compensation as defined under the contract. To determine the amount of revenue to recognize over time, the Company estimates profit by determining the difference between total estimated revenue and total estimated cost of a contract. In addition, the Company estimates a cost accrual every quarter that represents unbilled invoicing activity for services performed by subcontractors and suppliers during the quarter, and estimates revenue from the contract cost portion of this accrual based on current gross margin rates to be consistent with its cost method of revenue recognition. The estimated value of unbilled amounts are determined using a regression analysis that estimates value based on the Company’s historical experience, and is adjusted for large individual projects. The profit and corresponding revenue is recognized over the contract term based on costs incurred under the cost-to-cost method. The Company utilizes the cost-to-cost method as it believes cost incurred best represents the amount of work completed and remaining on projects, and is the most common basis for computing percentage of completion in the industry. For purposes of recognizing revenue, the Company follows the five-step approach outlined in Accounting Standards Codification (“ASC”)

606-10-25.

As the cost-to-cost method is driven by incurred cost, the Company calculates the percentage of completion by dividing costs incurred to date by the total estimated cost. The percentage of completion is then multiplied by estimated revenues to determine inception-to-date revenue. Revenue recognized for the period is the current inception-to-date recognized revenue less the prior period inception-to-date recognized revenue. If a contract is projected to result in a loss, the entire contract loss is recognized in the period when the loss was first determined and the amount of the loss is updated in subsequent reporting periods. Because the Company’s billings are based on contract terms and do not coincide with our progress in a project, revenue recognition also includes an amount related to a contract asset or contract liability. If the recognized revenue is greater than the amount billed to the customer, a contract asset is recorded. Additionally, the contract asset includes retainage billed to the customer that cannot be collected until the contract work has been completed and approved. Conversely, if the amount billed to the customer is greater than the recognized revenue, a contract liability is recorded. Additionally, the contract liability includes a liability for the excess of costs over revenues for all contracts that are in a loss position.

Contract costs incurred to date and expected total contract costs are continuously monitored during the term of the contract. Changes in the job performance, job conditions and final contract settlements are factors that influence management’s assessment of total contract value and the total estimated costs to complete those contracts, and therefore, profit and revenue recognition. Additionally, the Company estimates costs to complete on fixed price contracts which are determined on an individual contract basis by evaluating each project’s status as of the balance sheet date, and using our historical experience with the level of effort required to complete the underlying project. Claims and change orders are also measured based on our historical experience with individual customers and similar contracts, and are evaluated by management individually. A change order is a modification to a contract that changes the provisions of the contract, typically resulting from changes in scope, specifications, design, manner of performance, facilities, equipment, materials, sites, or period of completion of the work under the contract. A claim is an amount in excess of the agreed-upon contract price that the Company seeks to collect from its clients or others for client-caused delays, errors in specifications and designs, contract terminations, change orders that are either in dispute or are unapproved as to both scope and price, or other causes. The Company includes these estimated amounts of variable consideration to the extent that it is probable there will not be a significant reversal of revenue.

Some of the Company’s contracts may have contract terms that include variable consideration such as safety or performance bonuses or liquidated damages. In accordance with ASC

606-10-32, the Company estimates the variable consideration using one of two methods. In contracts in which there is a binary outcome, the most likely amount method is used. In instances in which there is a range of possible outcomes, the expected value method is used. In accordance with ASC 606-10-32-11,

the Company includes the estimated amount of variable consideration in the transaction price only to the extent that it is probable that a significant reversal in the amount of cumulative recognized revenue will not occur when the final outcome of the variable consideration is determined. In contracts in which a significant reversal may occur, the Company uses constraint in recognizing revenue on variable consideration. Although the Company often enters into contracts that contain liquidated damage clauses, the Company rarely incurs them, and as such, the Company does not include amounts associated with liquidated damage clauses until it is probable that liquidated damages will occur. These items are continually monitored by multiple levels of management throughout the reporting period.

A portion of the work the Company performs requires financial assurances in the form of performance and payment bonds or letters of credit at the time of execution of the contract. Many of the Company’s contracts include retention provisions of up to

10%,

which are generally withheld from each progress payment as retainage until the contract work has been completed and approved.

The Company provides warranties to customers on a basis customary to the industry; however, the warranty period does not typically exceed one year. Historically, warranty claims have not been material to the Company.

Total revenues do not include sales tax as the Company considers itself a pass-through conduit for collecting and remitting sales taxes. Sales tax and value added tax collected from customers is included in other current liabilities on the Company’s consolidated balance sheets.

Prior to January 1, 2018

the Company reported revenue under the accounting standard

Revenue Recognition (Topic

605

), under which revenues from long-term contracts were accounted for using the percentage-of-completion method of accounting. Under the percentage-of-completion method, the Company estimated profit as the difference between total estimated revenue and total estimated cost of a contract and recognized that profit over the contract term based on costs incurred under the cost-to-cost method.

Under Topic 605,

revenues from the Company’s construction services were performed under fixed-price, time-and-equipment, time-and-materials, unit-price, and cost-plus fee contracts. For fixed-price and unit-price contracts, the Company used the ratio of cost incurred to date on the contract to management’s estimate of the contract’s total cost, to determine the percentage of completion on each contract. This method was used as management considered expended costs to be the best available measure of progression of these contracts. Contract cost included all direct costs on contracts, including labor and material, subcontractor costs and those indirect costs related to contract performance, such as supplies, fuel, tool repairs and depreciation. The Company recognized revenues from construction services with fees based on time-and-materials, or cost-plus fee as the services were performed and amounts were earned. If contracts included contract incentive or bonus provisions, they were included in estimated contract revenues only when the achievement of such incentive or bonus was reasonably certain.

Under Topic 605,

contract costs incurred to date and expected total contract costs were continuously monitored during the term of the contract. Changes in job performance, job conditions and final contract settlements were factors that influenced management’s assessment of total contract value and the total estimated costs to complete those contracts and therefore, the Company’s profit recognition. These changes, which included contracts with estimated costs in excess of estimated revenues, were recognized in contract costs in the period in which the revisions were determined. At the point the Company anticipated a loss on a contract, the Company estimated the ultimate loss through completion and recognized that loss in the period in which the possible loss was identified.

Joint Ventures and Noncontrolling Interests

The Company accounts for investments in joint ventures using the proportionate consolidation method for income statement reporting and under the equity method for balance sheet reporting, unless the Company has a controlling interest causing the joint venture to be consolidated with equity owned by other joint venture partners recorded as noncontrolling interests. Under the proportionate consolidation method, joint venture activity is allocated to the appropriate line items found on the consolidated statements of operations in proportion to the percentage of participation the Company has in the joint venture. Under the equity method the net investment in joint ventures is stated as a single item on the consolidated balance sheets. For joint ventures which the Company does not have a controlling interest, the Company’s share of any profits and assets and its share of any losses and liabilities are recognized based on the Company’s stated percentage partnership interest in the joint venture, and are normally recorded by the Company one month in arrears. The investments in joint ventures are recorded at cost and the carrying amounts are adjusted to recognize the Company’s proportionate share of cumulative income or loss, additional contributions made and dividends and capital distributions received. The Company records the effect of any impairment or any other-than-temporary decrease in the value of the joint venture investment as incurred, which may or may not be one month in arrears, depending on when the Company obtains the joint venture activity information. Additionally, the Company continually assesses the fair value of its investment in unconsolidated joint ventures despite using information that is one month in arrears for regular reporting purposes. The Company includes only its percentage ownership of each joint venture in its backlog. See Note 16 — Noncontrolling Interests to the Financial Statements for further information related to joint ventures in which the Company has a majority controlling interest.

Foreign Currency

The functional currency for the Company’s Canadian operations is the Canadian dollar. Assets and liabilities denominated in Canadian dollars are translated into U.S. dollars at the end-of-period exchange rate. Revenues and expenses are translated using average exchange rates for the periods reported. Equity accounts are translated at historical rates. Cumulative translation adjustments are included as a separate component of accumulated other comprehensive income in shareholders’ equity. Foreign currency transaction gains and losses, arising primarily from changes in exchange rates on short-term monetary assets and liabilities, and ineffective long-term monetary assets and liabilities are recorded in the “other income, net” line on the consolidated statements of operations. For the year ended December 31, 2018, the Company recorded an insignificant amount of foreign currency losses. Effective foreign currency transaction gains and losses, arising primarily from long-term assets and liabilities are recorded in the foreign currency translation adjustment line on the consolidated statements of comprehensive income.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the period reported. Actual results could differ from those estimates.

The most significant estimates are related to estimates of costs to complete on contracts, pending change orders and claims, shared savings, insurance reserves, income tax reserves, estimates surrounding stock-based compensation, the recoverability of goodwill and intangibles and accounts receivable reserves. Actual results could differ from these estimates.

In 2018, the Company recognized revenues of $3.4 million related to significant change orders and/or claims that had been included as contract price adjustments on certain contracts which were in the process of being negotiated in the normal course of business.

The cost-to-cost method of accounting requires the Company to make estimates about the expected revenue and gross profit on each of its contracts in process. During the year ended December 31, 2018, changes in estimates pertaining to certain projects decreased consolidated gross margin by 0.7%, which resulted in decreases in operating income of $10.5 million, net income attributable to MYR Group Inc. of $8.2 million and diluted earnings per common share

attributable to MYR Group Inc.

of $0.49. The estimates are reviewed and revised quarterly, as needed. During the year ended December 31, 2017, changes in estimates pertaining to certain projects decreased consolidated gross margin by 0.7%, which resulted in decreases in operating income of $10.4 million, net income attributable to MYR Group Inc. of $6.2 million and diluted earnings per common share

attributable to MYR Group Inc. of

$0.38. During the year ended December 31, 2016, changes in estimates pertaining to certain projects decreased consolidated gross margin by 0.2%, which resulted in decreases in operating income of $2.6 million, net income attributable to MYR Group Inc. of $1.4 million and diluted earnings per common share attributable to MYR Group Inc. of $0.08.

Advertising

Advertising costs are expensed when incurred. Advertising costs, included in selling, general and administrative expenses, were $0.7 million, $0.7 million and $0.6 million for the years ended December 31, 2018, 2017 and 2016, respectively.

Income Taxes

The Company follows the liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recorded for future tax consequences of temporary differences between the financial reporting and tax basis of assets and liabilities, and are measured using the enacted tax rates and laws that are expected to be in effect when the underlying assets or liabilities are recovered or settled. The Company also evaluates whether the recorded deferred tax assets and valuation allowances can be realized and, when necessary, reduces the amounts to what is expected to be realized.

Interest and penalties related to uncertain income tax positions are included in income tax expense in the accompanying consolidated statements of operations. Interest and penalties actually incurred are charged to interest expense and the “other income, net” line, respectively.

Stock-Based Compensation

The Company determines compensation expense for stock-based awards based on the estimated fair values at the grant date and recognize the related compensation expense over the vesting period. The Company uses the straight-line amortization method to recognize compensation expense related to stock-based awards, such as restricted stock, restricted stock units and phantom stock units, that have only service conditions. This method recognizes stock compensation expense on a straight-line basis over the requisite service period for the entire award. The Company recognizes compensation expense related to performance awards that vest based on internal performance metrics and service conditions on a straight-line basis over the service period, but adjust inception-to-date expense based upon our determination of the potential achievement of the performance target at each reporting date. The Company recognizes compensation expense related to performance awards with market-based performance metrics on a straight-line basis over the requisite service period. Upon adoption ASU No.

Compensation

—

Stock Compensation (Topic 718)

in January of 2017, the Company elected to discontinue estimating future forfeitures and recognize forfeitures as they occur. Prior to the adoption, the Company used historical data to estimate the forfeiture rate applied to stock grants. Shares issued under the Company’s stock-based compensation program are taken out of authorized but unissued shares.

Earnings Per Share

The Company computes earnings per share using the treasury stock method. Under the treasury stock method, basic earnings per share attributable to MYR Group Inc. are computed by dividing net income attributable to MYR Group Inc. by the weighted average number of common shares outstanding during the period. Diluted earnings per share attributable to MYR Group Inc. are computed by dividing net income attributable to MYR Group Inc. by the weighted average number of common shares outstanding during the period plus all potentially dilutive common stock equivalents, except in cases where the effect of the common stock equivalent would be anti-dilutive.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. As of December 31, 2018 and 2017, the Company held its cash in checking accounts or in highly liquid money market funds. The Company’s banking arrangements allow the Company to fund outstanding checks when presented to financial institutions for payment. The Company funds all intraday bank balances overdrafts during the same business day. Checks issued and outstanding in excess of bank balance are recorded in accounts payable in the Consolidated Balance Sheets and are reflected as a financing activity in the Consolidated Statements of Cash Flows.

Accounts Receivable and Allowance for Doubtful Accounts

The Company does not charge interest to its customers and carries its customer receivables at their face amounts, less an allowance for doubtful accounts. Based on the Company’s experience in recent years, the majority of customer balances at each balance sheet date are collected within twelve months. As is common practice in the industry, the Company classifies all accounts receivable as current assets.

The Company grants trade credit, on a non-collateralized basis (with the exception of lien rights against the property in certain cases), to its customers and is subject to potential credit risk related to changes in business and overall economic activity. The Company analyzes specific accounts receivable balances, historical bad debts, customer credit-worthiness, current economic trends and changes in customer payment terms when evaluating the adequacy of the allowance for doubtful accounts. In the event that a customer balance is deemed to be uncollectible, the account balance is written-off against the allowance for doubtful accounts.

Classification of Contract Assets and Liabilities

The Company recognizes revenue associated with its contracts with customers over time, for which the Company has an enforceable right to receive compensation. Many of our contracts contain specific provisions that determine when the Company can bill for its work performed under these contracts. Any revenue earned on a contract that has not yet been billed to the customer is recorded as a contract asset on the Company’s consolidated balance sheets. Contract retainages associated with contract work that has been completed and billed but not paid by its customers until the contracts are substantially complete, pursuant to contract retainage provisions under the contract, are also included in contract assets. The allowance for collection of contract retainage was not significant as of December 31, 2018 and 2017.

The Company’s consolidated balance sheets present contract liabilities which contain deferred revenue that represent any costs incurred on contracts in process for which revenue has not yet been recognized. Additionally, accruals for contracts in a loss provision are included in contract liabilities.

Property and Equipment

Property and equipment is carried at cost. Depreciation is computed using the straight-line method over estimated useful lives. Major modifications or refurbishments which extend the useful life of the assets are capitalized and depreciated over the adjusted remaining useful life of the assets. Upon retirement or disposition of property and equipment, the cost and related accumulated depreciation are removed and any resulting gain or loss is recognized in income from operations. The cost of maintenance and repairs is charged to expense as incurred. Property and equipment is reviewed for impairment and tested for recoverability whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the carrying value of property and equipment exceeds its fair value, an impairment charge would be recorded in the statement of operations.

Leases

The Company leases certain real estate, construction equipment and office equipment. Real estate is generally leased for terms up to ten years in duration. The terms and conditions of leases (such as renewal or purchase options and escalation clauses), if material, are reviewed at inception to determine the classification (operating or capital) of the lease. Nonperformance-related default covenants, cross-default provisions, subjective default provisions and material adverse change clauses contained in material lease agreements, if any, are also evaluated to determine whether those clauses affect lease classification in accordance with ASC Topic 840-10-25.

Insurance

The Company carries insurance policies,

which are subject to certain deductibles, for workers’ compensation, general liability, automobile liability and other coverages. The deductible for each line of coverage is up to $

1.0

million, except for wildfire coverage which has a deductible of $

2.0

million. Certain health benefit plans are subject to a deductible up to $

0.2

million, for qualified individuals. Losses up to the deductible amounts are accrued based upon the Company’s estimates of the ultimate liability for claims reported and an estimate of claims incurred but not yet reported.

The insurance and claims accruals are based on known facts, actuarial estimates and historical trends. While recorded accruals are based on the ultimate liability, which includes amounts in excess of the deductible, a corresponding receivable for amounts in excess of the deductible is included in current assets in the consolidated balance sheets.

Goodwill and Intangible Assets

Goodwill and intangible assets with indefinite lives are not amortized. Intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives. The Company reviews goodwill and intangible assets with indefinite lives for impairment on an annual basis at the beginning of the fourth quarter, or when circumstances change, such as a significant adverse change in the business climate or the decision to sell a business, both of which would indicate that impairment may have occurred. Intangible assets with finite lives are also reviewed for impairment and tested for recoverability whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. The Company may perform either a qualitative assessment or a two-step goodwill impairment test. The qualitative assessment considers financial, industry, segment and macroeconomic factors. If the qualitative assessment indicates a potential for impairment, the two-step method is used to determine if impairment exists. The two-step method begins with a comparison of the fair value of the reporting unit with its carrying value. If the carrying amount of the reporting unit exceeds its fair value, the second step of the process involves a comparison of the implied fair value and carrying value of the goodwill of that reporting unit. The company also performs a qualitative assessment on intangible assets with indefinite lives. If the qualitative assessment indicates a potential for impairment, a quantitative impairment test would be performed to compare the fair value of the indefinite-lived intangible asset with its carrying value. If the carrying value of goodwill or other indefinite-lived assets exceeds its implied fair value, an impairment charge would be recorded in the statement of operations.

As a result of the annual qualitative review process in 2017 and 2016, the Company determined it was not necessary to perform a two-step analysis.

In 2018,

the Company performed a two-step analysis on goodwill and intangible assets with indefinite lives. The first step involves a comparison of the fair value of the reporting unit with its carrying value. If the carrying amount of the reporting unit exceeds its fair value, the second step of the process involves a comparison of the implied fair value and carrying value of the goodwill of that reporting unit. If the carrying value of goodwill exceeds its implied fair value, an impairment charge is recorded in the statement of operations. The step-one analysis did not indicate that the Company’s goodwill or indefinite-lived intangible assets were impaired. As a result, no step-two analysis was performed.

Concentrations

Financial instruments that potentially subject the Company to a concentration of credit risk consist principally of cash and cash equivalents and accounts receivable. The Company maintains substantially all of its cash and cash equivalent balances with large financial institutions which are believed to be high quality institutions.

The Company is subject to a concentration of risk because it derives a significant portion of its revenues from a few customers. The Company’s top ten customers accounted for approximately 32.9%, 40.4%, and 46.4% of consolidated revenues for the years ended December 31, 2018, 2017 and 2016, respectively. For the year ended December 31, 2017, one T&D customer accounted for 10.7% of our revenues. For the years ended December 31, 2018 and 2016, no single customer accounted for more than 10.0% of annual revenues.

The Company grants trade credit under contractual payment terms, generally without collateral, to its customers, which include high credit quality electric utilities, governmental entities, general contractors and builders, owners and managers of commercial and industrial properties. Consequently, the Company is subject to potential credit risk related to changes in business and economic factors. However, the Company generally has certain statutory lien rights with respect to services provided. Under certain circumstances such as foreclosures or negotiated settlements, the Company may take title to the underlying assets in lieu of cash in settlement of receivables. As of December 31, 2018 and 2017, none of our customers individually exceeded 10.0% of accounts receivable. The Company believes the terms and conditions in its contracts, billing and collection policies are adequate to minimize the potential credit risk.

As of December 31, 2018, approximately 88% of the Company’s craft labor employees were covered by collective bargaining agreements. Although the majority of these agreements prohibit strikes and work stoppages, the Company cannot be certain that strikes or work stoppages will not occur in the future.

Recent Accounting Pronouncements

Changes to GAAP are typically established by the Financial Accounting Standards Board (“FASB”) in the form of accounting standards updates (“ASUs”) to the FASB’s Accounting Standards Codification (“ASC”). The Company considers the applicability and impact of all ASUs. The Company, based on its assessment, determined that any recently issued or proposed ASUs not listed below are either not applicable to the Company or may have minimal impact on its Financial Statements.

Recently Adopted Accounting Pronouncements

In May 2014, the FASB issued ASU No. 2014-09,

Revenue from Contracts with Customers (Topic

606)

. The amendments under this pronouncement changed how an entity recognizes revenue from contracts it enters to transfer goods, services or nonfinancial assets to its customers. These changes created a comprehensive framework for all entities in all industries to apply in the determination of when to recognize revenue, and, therefore, supersede virtually all existing revenue recognition requirements and guidance. This framework is expected to result in less complex guidance in application while providing a consistent and comparable methodology for revenue recognition. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, the amendments require expanded disclosure to enable the users of the financial statements to understand the nature, timing and uncertainty of revenue and cash flow arising from contracts with customers. On January 1, 2018, the Company adopted this ASU on a modified retrospective basis. Results for reporting periods beginning after January 1, 2018 are presented under

Revenue from Contracts with Customers (Topic 606)

, while prior period amounts

reported on the Company’s consolidated statement of operations

were

not adjusted and continue to be reported in accordance with the Company’s historical accounting under Revenue Recognition Topic 605. See Note 3

—

Revenue Recognition to the Financial Statements for further information related to the Company’s accounting policy and transition disclosures associated with the adoption of this pronouncement.

In January 2017, the FASB issued ASU No. 2017-01,

Business Combinations (Topic 805): Clarifying the Definition of a Business

, which clarified the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The Company adopted this ASU on a prospective basis in January 2018 and there was no effect on the Company’s financial position, results of operations or cash flows.

In October 2016, the FASB issued ASU No. 2016-16,

Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory

, which modified existing guidance and intended to reduce the diversity in practice with respect to the accounting for income tax consequences of intra-entity transfers of assets. This update requires entities to immediately recognize the tax consequences on intercompany asset transfers (excluding inventory) at the transaction date, and eliminated the recognition exception within previous guidance. The Company adopted this ASU using a modified retrospective approach in January 2018 and there was no effect on the Company’s financial position, results of operations or cash flows.

In August 2016, the FASB issued ASU No. 2016-15,

Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments

, which intended to reduce diversity in practice in how eight specific transactions are classified in the statement of cash flows. The Company adopted this ASU on a retrospective basis in January 2018 and there was no effect on the Company’s financial position, results of operations or cash flows.

Recently Issued Accounting Pronouncements

In January 2017, the FASB issued ASU No. 2017-04,

Intangibles

—

Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment

, which simplifies the subsequent measurement of goodwill, through elimination of Step 2 from the goodwill impairment test. Instead, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. The update is effective for any annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The guidance requires application on a prospective basis. The Company does not expect that this pronouncement will have a significant impact on its financial statements.

In February 2016, the FASB issued ASU No. 2016-02,

Leases (Topic 842)

. The amendments under this pronouncement will change the way all leases with durations in excess of one year are treated. Under this guidance, lessees will be required to recognize virtually all leases on the balance sheet as a right-of-use asset and an associated financing lease liability or capital lease liability. The right-of-use asset represents the lessee’s right to use, or control the use of, a specified asset for the specified lease term. The lease liability represents the lessee’s obligation to make lease payments arising from the lease, measured on a discounted basis. Based on certain characteristics, leases are classified as financing leases or operating leases. Financing lease liabilities, which contain provisions similar to capitalized leases, are amortized like capital leases under current accounting, as amortization expense and interest expense in the statement of operations. Operating lease liabilities are amortized on a straight-line basis over the life of the lease as lease expense in the statement of operations. This update is effective for annual reporting periods, and interim periods within those reporting periods, beginning after December 15, 2018. The Company intends to adopt this new guidance using the cumulative effect method, which would apply to all new lease contracts initiated on or after January 1, 2019. For existing lease contracts that have remaining obligations as of January 1, 2019, the difference between the recognition criteria in the new guidance and the Company’s current practices would be recognized using a cumulative effect adjustment to the opening balance of retained earnings.

The Company continues to evaluate the impact that this pronouncement, and all amendments relating to this pronouncement, will have on its policies and procedures pertaining to its existing and future lease arrangements, disclosure requirements and on the Company’s financial statements. The Company has appointed a committee to transition its policies and procedures based on the requirements of this pronouncement and has purchased lease software to support the additional requirements relating to this pronouncement.

When this pronouncement is adopted in 2019, the

Company

expects that most existing operating lease commitments that extend beyond twelve months at the time of adoption will be recognized as lease liabilities and right-of-use (“ROU”) assets upon adoption. Based on preliminary evaluations, the Company estimates that the value of lease liabilities will be between $17 million and $19 million upon adoption with corresponding ROU assets of the same amount based on the present value of the remaining minimum lease payments under current leasing standards. Additionally, we expect to elect the

’

package of practical expedients,’ which permits the Company to not reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. The Company currently does not expect to elect the use of the hindsight practical expedient or the practical expedient pertaining to land easements. The Company, however, expects to elect the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, the Company will not recognize ROU assets or lease liabilities, and this includes not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition. The Company also currently expects to elect the practical expedient to not separate lease and non-lease components for our real estate and vehicle leases. While the Company is still evaluating the requirements of this update, it currently does not expect the adoption to have a material impact on the recognition, measurement or presentation of lease expenses within the Consolidated Statements of Operations and Comprehensive Income or Consolidated Statements of Cash Flows.

Acquisitions

2. Acquisitions

Huen Electric, Inc.

On July 2, 2018,

the Company completed the acquisition of substantially all of the assets of Huen Electric, Inc., an electrical contracting firm based in Illinois, Huen Electric New Jersey Inc., an electrical contracting firm based in New Jersey, and Huen New York, Inc., an electrical contracting firm based in New York (collectively, the “Huen Companies”). The Huen Companies provide a wide range of commercial and industrial electrical construction capabilities under the Company’s C&I segment in Illinois, New Jersey and New York. The total consideration paid was approximately

47.1

million, subject to working capital and net asset adjustments, which was funded through borrowings on the line of credit. Total consideration paid may include a portion subject to potential net asset adjustments which are expected to be finalized in early 2019. The Company’s preliminary estimate of these net asset adjustments was approximately

10.7

million as of the July 2, 2018 closing date and approximately $11.2 million as of December 31, 2018,

which will increase the total consideration to be paid, and is recorded in other current liabilities on the consolidated balance sheets.

The purchase agreement also includes contingent consideration provisions for margin guarantee adjustments based upon performance subsequent to the acquisition on certain contracts. The contracts are valued at fair value at the acquisition date, causing no margin guarantee estimate or adjustments for fair value. Changes in contract estimates, such as modified costs to complete or change order recognition, have resulted and will continue to result in changes to these margin guarantee estimates. Changes in contingent consideration, subsequent to the acquisition, related to the margin guarantee adjustments on certain contracts of approximately

$3.9 million were recorded in other expense for the year ended

December 31, 2018

. Future margin guarantee adjustments, if any, are expected to be recognized through

2019

. The Company could also be required to make compensation payments contingent on the successful achievement of certain performance targets and continued employment of certain key executives of the Huen Companies. These payments are recognized as compensation expense in the consolidated statements of operations as incurred. For the year ended

December 31, 2018

the Company recognized $

0.6 million of compensation expense associated with these contingent payments.

The results of operations for Huen Companies are included in the Company’s consolidated statement of operations and the C&I segment from the date of acquisition. Costs of approximately $0.3 million related to the acquisition were included in selling, general and administrative expenses in the consolidated statement of operations for the year ended December 31, 2018.

The following table summarizes the preliminary allocation of the opening balance sheet from the date of acquisition through December 31, 2018:

(in thousands)	(as of acquisition date) July 2, 2018			Measurement Period Adjustments			Adjusted acquisition amounts as of December 31, 2018

Fair value of aquired noncontrolling interests		(1,273	)		(7	)		(1,280	)
Goodwill	$	24,111		$	(14,500	)	$	9,611

The Company has developed preliminary estimates of fair value of the assets acquired and liabilities assumed for the purposes of allocating the purchase price. In conjunction with the acquisition of the Huen Companies, the Company acquired a majority-ownership of an ongoing joint venture. The assets acquired within the joint venture are recorded at their fair value at the time of the acquisition, relate to a specific contract, and no assets or liabilities outside of the operations of the contract existed at the acquisition date. The goodwill to be recognized, which represents the excess of the purchase price over the net amount of the fair values assigned to assets acquired and liabilities assumed, is primarily attributable to the value of an assembled workforce and other non-identifiable assets. No synergies were anticipated in the acquisition as the three companies will function as individual districts within the Company’s operating structure. There may be further adjustments to the total consideration as the net asset adjustments are finalized. Additionally, the Company will perform an analysis of the purchase price allocation and make appropriate adjustments based on the analysis. All of the goodwill and identifiable intangible assets are expected to be tax deductible per applicable Internal Revenue Service regulations.

The following unaudited supplemental pro forma results of operations have been provided for illustrative purposes only and do not purport to be indicative of the actual results that would have been achieved by the combined companies for the periods presented or that may be achieved by the combined companies in the future. Future results may vary significantly from the results reflected in the following pro forma financial information because of future events and transactions, as well as other factors:

	Year ended December 31,
(In thousands, except per share data)	2018		2017
	(unaudited)		(unaudited)
Contract revenues	$	1,612,618	$	1,523,328
Net income	$	35,872	$	26,531
Net income attributable to MYR Group, Inc.	$	34,947	$	25,561
Income per common share:
– Basic	$	2.13	$	1.57
– Diluted	$	2.11	$	1.55
Weighted average number of common shares and potential common shares outstanding:
– Basic		16,441		16,273
– Diluted		16,585		16,496

The pro forma combined results of operations for years ended December 31, 2018 and 2017 were prepared by adjusting the historical results of the Company to include the historical results of the Huen Companies as if the acquisition occurred on January 1, 2017. These pro forma results were adjusted for the following:



To include additional depreciation associated with the estimated step-up in fair value of the property and equipment acquired.



To record the net reduction in lease expense associated with the revised real estate lease contracts that were completed at the time of the acquisition.



To record transaction costs associated with the acquisition.



To record the estimated amortization related to the acquired intangible assets discussed above.



To record the additional interest expense related to the incremental borrowings of $

47.1

million on the Company’s credit facility as if the borrowing occurred on January 1, 2017.



To reflect the income tax effect of pro forma adjustments at the statutory tax rate.



To record estimated compensation payments contingent on the successful achievement of certain performance targets.

Revenues of approximately $69.0 million and income before income taxes of approximately $0.5 million, were included in the Company’s consolidated results of operations for the year ended December 31, 2018 related to the acquisition of the Huen Companies.

Western Pacific Enterprises Ltd.

On October 28, 2016, the Company completed the acquisition of substantially all of the assets of Western Pacific Enterprises GP and Western Pacific Enterprises Ltd., except for certain real estate owned by Western Pacific Enterprises Ltd., with the company continuing operations under the name Western Pacific Enterprises Ltd. (“WPE”), an electrical contracting firm in western Canada. With its main headquarters in Coquitlam, British Columbia, WPE provides a wide range of commercial and industrial electrical construction capabilities under the Company’s C&I segment. WPE also provides substation construction capabilities under the Company’s T&D segment. The total consideration paid was approximately $12.1 million, which was funded through borrowings from our line of credit. Total consideration paid included $2.2 million subject to potential net asset adjustments. These net asset adjustments were approximately $0.8 million as of the October 28, 2016 closing date and as of December 31, 2017. The Company accounted for the net asset adjustments as a reduction to consideration paid which was funded through the return of funds held in a $1.9 million escrow account, established at the time of purchase. The purchase agreement also included provisions for margin guarantee adjustments based upon performance subsequent to the acquisition on certain contracts. In early 2018, the Company finalized an agreement to settle all amounts outstanding under the margin guarantee adjustment provision as well as previous contingent compensation agreements that were being recognized as compensation expense in the consolidated statement of operations as incurred. As a result, the Company recorded other expense of $2.3 million for the year ended December 31, 2017 and reversed the compensation expense that was previously recorded. The Company had previously recognized other income of $1.4 million relating to the margin guarantee adjustments provision for the year ended December 31, 2016.

3. Revenue Recognition

Change in Accounting Policy

On January 1, 2018, the Company adopted ASU No. 2014-09,

Revenue from Contracts with Customers (Topic 606)

using the modified retrospective method for contracts that were not completed as of January 1, 2018. Results on the Company’s consolidated statement of operations for reporting periods beginning after December 31, 2017 are presented under this new pronouncement, while prior period amounts reported on the Company’s consolidated statement of operations are not adjusted and continue to be reported under the accounting standard Revenue Recognition Topic 605, which was in effect for prior periods. In connection with the adoption of this ASU, certain changes have been made to the Company’s consolidated balance sheet. The accounts previously named “Costs and estimated earnings in excess of billings on uncompleted contracts” and “Billings in excess of costs and estimated earnings on uncompleted contracts” have been renamed “Contract assets” and “Contract liabilities”, respectively. In addition, contract retainages previously classified in accounts receivable, net of allowances were reclassified into contract assets and accruals for contracts in a loss position previously classified in other current liabilities were reclassified into contract liabilities.

The Company

recorded an increase to opening retained earnings of $0.7 million, net of tax, as of January 1, 2018 due to the cumulative impact of adopting Topic 606, representing revenues which would have been recognized in prior periods under Topic

606

. The impact of adopting Topic

606

for

2018

was an increase of $

0.2

million to revenue. The cumulative adjustment and the impact experienced during

2018

were due to accelerated recognition of contract provisions related to variable consideration previously not permitted to be recognized under Topic

605

until no remaining contingency existed related to this consideration. For additional information related to impact of this

pronouncement, see Note 1 — Organization, Business and Summary of Significant Accounting Policies to our Financial Statements.

Disaggregation of Revenue

A majority of the Company’s revenues are earned through contracts with customers that normally provide for payment upon completion of specified work or units of work as identified in the contract. Although there is considerable variation in the terms of these contracts, they are primarily structured as fixed-price contracts, under which the Company agrees to do the entire project for a fixed amount, or unit-price contracts, under which the Company agrees to do the work at a fixed price per unit of work as specified in the contract. The Company also enters into time-and-equipment and time-and-materials contracts under which the Company is paid for labor and equipment at negotiated hourly billing rates and for other expenses, including materials, as

incurred

at rates agreed to in the contract

. Finally, the Company sometimes enters into cost-plus contracts, where the Company is paid for costs plus a negotiated margin. On occasion, time-and-equipment, time-and-materials and cost-plus contracts require the Company to include a guaranteed not-to-exceed maximum price.

Historically, fixed-price and unit-price contracts have had the highest potential margins; however, they have had a greater risk in terms of profitability because cost overruns may not be recoverable. Time-and-equipment, time-and-materials and cost-plus contracts have historically had less margin upside, but generally have had a lower risk of cost overruns. The Company also provides services under master service agreements (“MSAs”) and other variable-term service agreements. MSAs normally cover maintenance, upgrade and extension services, as well as new construction. Work performed under MSAs is typically billed on a unit-price, time-and-materials or time-and-equipment basis. MSAs are typically one to three years in duration; however, most of the Compa

ny’s contracts, includin

g MSAs, may be terminated by the customer on short notice, typically 30 to 90 days, even if the Company is not in default under the contract. Under MSAs, customers generally agree to use the Company for certain services in a specified geographic region. Most MSAs include no obligation for the contract counterparty to assign specific volumes of

work to the Company and do not require the counterparty to use the Company exclusively, although in some cases the MSA contract gives the Comp

any a right of first refusal for certain work. Additional information related to the Company’s market types is provided in Note 16

Contract Assets and Liabilities

Contracts with customers usually stipulate the timing of payment, which is defined by the terms found within the various contracts under which work was performed during the period. Therefore, contract assets and liabilities are created when the timing of costs incurred on work performed does not coincide with the billing terms, which frequently include retention provisions contained in each contract.

The Company’s consolidated balance sheets present contract assets which contains unbilled revenue (previously identified as costs and estimated earnings in excess of billings) and contract retainages associated with contract work that has been completed and billed but not paid by customers, pursuant to retainage provisions, which are generally due once the job is completed and approved. The allowance for collection of contract retainage was not significant as of December 31, 2018 and 2017.

Contract assets consisted of the following at December 31:

(in thousands)	2018		2017		Change
Unbilled revenue	$	111,153	$	78,260	$	32,893
Contract retainages, net		49,128		42,732		6,396
Contract assets	$	160,281	$	120,992	$	39,289

The Company’s consolidated balance sheets present contract liabilities which contains deferred revenue (previously identified as billings in excess of costs and estimated earnings on uncompleted contracts) and an accrual for contracts in a loss provision.

Contract liabilities consisted of the following at December 31:

(in thousands)	2018		2017		Change
Deferred revenue	$	57,051	$	28,919	$	28,132
Accrued loss provision		1,483		1,305		178
Contract liabilities	$	58,534	$	30,224	$	28,310

The following table provides information about contract assets and contract liabilities from contracts with customers:

(in thousands)	2018			2017			Change

Net contract assets (liabilities)	$	101,747		$	90,768		$	10,979

The difference between the opening and closing balances of the Company’s contract assets and contract liabilities primarily results from the timing of the Company’s performance and customer payment. The amount of revenue recognized in the period that was included in the opening contract liability balances was $

22.1 million for

2018

. This revenue consists primarily of work performed on previous billings to customers.

Remaining Performance Obligations

December 31, 2018

, the Company had $1.06 billion of remaining performance obligations. The Company’s remaining performance obligations includes projects that have a written award, a letter of intent, a notice to proceed or an agreed upon work order to perform work on mutually accepted terms and conditions. The following table summarizes that amount of remaining performance obligations that the Company expects to be realized as of

December 31, 2018

and the amount of the remaining performance obligations that the Company reasonably estimates will not be recognized within the next twelve months.

	Remaining Performance Obligations as of December 31, 2018
(In thousands)	Total		Amount estimated to not be recognized within 12 months
T&D	$	418,178	$	19,698
C&I		644,547		167,652
Total	$	1,062,725	$	187,350

The Company expects a vast majority of the remaining performance obligations to be recognized within twenty-four months, although the timing of the Company’s performance is not always under its control. Additionally, the difference between the remaining performance obligations and backlog is due to the exclusion of a portion of the Company’s MSAs under certain contract types from the Company’s remaining performance obligations as these contracts can be canceled for convenience at any time by the Company or the customer without considerable cost incurred by the customer. Additional information related to backlog is provided in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

4. Fair Value Measurements

The Company uses the three-tier hierarchy of fair value measurement, which prioritizes the inputs used in measuring fair value based upon their degree of availability in external active markets. These tiers include: Level 1 (the highest priority), defined as observable inputs, such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3 (the lowest priority), defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

As of December 31, 2018 and 2017, the Company determined that the carrying value of cash and cash equivalents approximated fair value based on Level 1 inputs. As of December 31, 2018 and 2017, the fair value of the Company’s long-term debt and capital lease obligations, were based on Level 2 inputs. The Company’s long-term debt was based on variable and fixed interest rates at December 31, 2018 and variable interest rates at December 31, 2017. Long-term debt with variable interest rates was based on rates for new issues with similar remaining maturities and approximated carrying value. In addition, based on borrowing rates currently available to the Company for borrowings with similar terms, the carrying values of the Company’s capital lease obligations and long term debt with fixed interest rates also approximated fair value.

- Definition

The increase in goodwill as of December 31, 2018 compared to December 31, 2017 was due to the allocation of $9.6 million of goodwill related to the

acquisition of the

Huen

Companies identified during the ongoing analysis of the purchase accounting.

The increase in intangible

assets also related to the

acquisition of the

Huen

Companies and are being amortized on a straight-line basis over periods ranging up to 12 years. Additional financial information related to this acquisition is provided in Note 2 — Acquisitions to the Financial Statements. Immaterial foreign currency translation adjustments related to goodwill and intangible assets are netted with the amounts indicated above.

Customer relationships and backlog are being amortized on a straight-line method over an estimated useful life

ranging up to

12 years and the remaining life of the contract, respectively, and have been determined to have no residual value. Amortizable trade names are being amortized on a straight-line basis over an estimated useful life of approximately 15 years. Certain trade names have indefinite lives and, therefore, are not being amortized. Intangible asset amortization expense was $1.8 million, $0.5 million and $0.9 million for the years ended December 31, 2018, 2017 and 2016, respectively.

As of December 31, 2018, estimated future intangible asset amortization expense for the each of the next five years and thereafter was as follows:

Credit Agreement

June 30, 2016, the Company entered into a five-year amended and restated credit agreement, as amended from time to time (the “Credit Agreement”), with a syndicate of banks led by JPMorgan Chase Bank, N.A. and Bank of America, N.A, that provided for a $250 million facility (the “Facility”), which could be used for revolving loans and letters of credit. On September 28, 2018, the Company amended the Credit Agreement. This amendment, among other things, reduces the amount of the Facility available to be used for letters of credit to a maximum of $150 million. The Facility also allows for revolving loans and letters of credit in Canadian dollars and other currencies, up to the U.S. dollar equivalent of $50 million. The Company has an expansion option to increase the commitments under the Facility or enter into incremental term loans, subject to certain conditions, by up to an additional $100 million upon receipt of additional commitments from new or existing lenders. Subject to certain exceptions, the Facility is secured by substantially all of the assets of the Company and its domestic subsidiaries and by a pledge of substantially all of the capital stock of the Company’s domestic subsidiaries and 65% of the capital stock of the direct foreign subsidiaries of the Company. Additionally, subject to certain exceptions, the Company’s domestic subsidiaries also guarantee the repayment of all amounts due under the Credit Agreement. If an event of default occurs and is continuing, on the terms and subject to the conditions set forth in the Credit Agreement, amounts outstanding under the Facility may be accelerated and may become or be declared immediately due and payable. Borrowings under the Credit Agreement are used for working capital, capital expenditures, acquisitions, stock repurchases and other general corporate purposes.

Amounts borrowed under the Credit Agreement bear interest, at the Company’s option, at a rate equal to either (1) the Alternate Base Rate (as defined in the Credit Agreement), plus an applicable margin ranging from 0.00

% to

1.00%; or (2) Adjusted LIBO Rate (as defined in the Credit Agreement) plus an applicable margin ranging from 1.00

% to

2.00%. The applicable margin is determined based on the Company’s consolidated leverage ratio (the “Leverage Ratio”) which is defined in the Credit Agreement as Consolidated Total Indebtedness divided by Consolidated EBITDA (as defined in the Credit Agreement). Letters of credit issued under the Facility are subject to a letter of credit fee of 1.125% to 2.125% for non-performance letters of credit or 0.625

% to

1.125% for performance letters of credit, based on the Company’s consolidated Leverage Ratio. The Company is subject to a commitment fee of 0.20

% to

0.375%, based on the Company’s consolidated Leverage Ratio, on any unused portion of the Facility. The Credit Agreement restricts certain types of payments when the Company’s consolidated Leverage Ratio exceeds 2.25. The weighted average interest rate on borrowings outstanding on the Facility for the year ended

December 31, 2018

was 3.08

% per annum.

Under the Credit Agreement, the Company is subject to certain financial covenants and must maintain a maximum consolidated Leverage Ratio of 3.0 and a minimum interest coverage ratio of

3.0

, which is defined in the Credit Agreement as Consolidated EBITDA (as defined in the Credit Agreement) divided by interest expense (as defined in the Credit Agreement). The Credit Agreement also contains a number of covenants, including limitations on asset sales, investments, indebtedness and liens. In connection with any permitted acquisition where the total consideration exceeds $50 million, the Company may request that the maximum permitted consolidated Leverage Ratio increase from 3.0 to 3.5. Any such increase shall begin in the quarter in which such permitted acquisition is consummated and shall continue in effect for four consecutive fiscal quarters. The Company was in compliance with all of its financial covenants under the Credit Agreement as of

December 31, 2018

As of

December 31, 2018

, the Company had letters of credit outstanding under the Facility of approximately $21.2

million, including $

17.6

million related to the Company’s payment obligation under its insurance programs and approximately $

3.6 million related to contract performance obligations. As of December 31, 2017

, the Company had letters of credit outstanding under the Facility of approximately $

20.9

million, including $

17.6

million related to the Company’s payment obligation under its insurance programs and approximately $

3.3 million related to contract performance obligations.

The Company has remaining deferred debt issuance costs totaling $

0.6 million as of

December 31, 2018

, related to the line of credit. As permitted under ASU No. 2015

, debt issuance costs have been deferred and are presented as an asset within other assets, which is amortized as interest expense over the term of the line of credit.

Equipment Notes

On September 28, 2018, the Company entered into a Master Equipment Loan and Security Agreement (the “Master Loan Agreement”) with Banc of America Leasing & Capital, LLC (“BofA”). The Master Loan Agreement may be used for the financing of equipment between the Company and BofA pursuant to one or more “Equipment Notes”. Each Equipment Note executed under the Master Loan Agreement constitutes a separate, distinct and independent financing of equipment and a contractual obligation of the Company, which may contain prepayment clauses.

As of December 31, 2018, we have five Equipment Notes outstanding under the Master Loan Agreement that are collateralized by equipment and vehicles owned by the Company. The following table sets forth our remaining principal payments for the Company’s outstanding Equipment Notes as of December 31, 2018:

The Company determined that it is more-likely-than-not that it will not realize the deferred tax assets on certain Canadian subsidiaries and recorded a valuation allowance against the entire related deferred tax assets.

As of December 31, 2018, the Company had no undistributed earnings of our Canadian subsidiaries. We expect future earnings to be reinvested. Accordingly, as of December 31, 2018 no provision for U.S. income taxes or foreign withholding taxes has been made.

The Company is subject to taxation in various jurisdictions.

The Company is currently under examination by U. S. federal authorities for its 2016

tax returns and

its 2017 tax return is

subject

to examination by U. S. federal authorities. The Company’s tax returns are subject to examination by various state authorities for the years 2014 through 2017.

The Company has recorded a liability for unrecognized tax benefits related to tax positions taken on its various income tax returns. If recognized, the entire amount of unrecognized tax benefits would favorably impact the effective tax rate that is reported in future periods. The decrease in the unrecognized tax benefits as of

December 31, 2018

was primarily due to the reclassification of reserves for state tax expenses from unrecognized tax benefits to deferred tax liability during the year ended December 31, 2018. These state tax expenses were deducted on the federal tax returns for the

2011 through 2017. The total unrecognized tax benefits is expected to be reduced by less than $

0.1

million within the next 12 months. Interest and penalties related to uncertain income tax positions are included as a component of income tax expense in the Financial Statements.

The following is a reconciliation of the beginning and ending liability for unrecognized tax benefits at December 31:

(in thousands)	2018			2017
Balance at beginning of period	$	751		$	271
Gross increases in current period tax positions		25			63
Gross increases in prior period tax positions		—			434

Balance at end of period		327			751
Accrued interest and penalties at end of period		48			36
Total liability for unrecognized tax benefits	$	375		$	787

The liability for unrecognized tax benefits, including accrued interest and penalties, was included in other liabilities in the accompanying consolidated balance sheets. The amount of interest and penalties charged or credited to income tax expense as a result of the unrecognized tax benefits was not significant in the years ended December 31, 2018, 2017 and 2016.

Purchase Commitments

As of

December 31, 2018

, the Company had approximately $

15.0 million in outstanding purchase orders for certain construction equipment, with cash outlay scheduled to occur over the next nine months.

Insurance and Claims Accruals

The Company carries insurance policies, which are subject to certain deductibles, for workers’ compensation, general liability, automobile liability and other coverages. The deductible per occurrence for each line of coverage is up to $1.0

million, except for wildfire coverage which has a deductible of $

2.0

million. The Company’s health benefit plans are subject to deductibles of up to $

0.2 million for qualified individuals. Losses up to the deductible amounts are accrued based upon the Company’s estimates of the ultimate liability for claims reported and an estimate of claims incurred but not yet reported.

Insurance expense, including premiums, for workers’ compensation, general liability, automobile liability, employee health benefits, and other coverages for the years ended December 31, 2018, 2017 and 2016 was $30.4 million, $29.5 million and $25.6 million, respectively.

Performance and Payment Bonds and Parent Guarantees

In certain circumstances, the Company is required to provide performance and payment bonds in connection with its future performance on certain contractual commitments. The Company has indemnified its sureties for any expenses paid out under these bonds. As of

December 31, 2018

, an aggregate of approximately $

614.9 million in original face amount of bonds issued by the Company’s sureties were outstanding. Our estimated remaining cost to complete these bonded projects was approximately $324.7

million as of

December 31, 2018

From time to time the Company guarantees the obligations of wholly owned subsidiaries, including obligations under certain contracts with customers, certain lease agreements, and obligations in connection with obtaining contractors’ licenses. Additionally, from time to time the Company is required to post letters of credit to guarantee the obligations of its wholly owned subsidiaries, which reduces the borrowing availability under our Facility.

Indemnities

From time to time, pursuant to its service arrangements, the Company indemnifies its customers for claims related to the services it provides under those service arrangements. These indemnification obligations may subject the Company to indemnity claims, liabilities and related litigation. The Company is not aware of any material unrecorded liabilities for asserted claims in connection with these indemnification obligations.

Collective Bargaining Agreements

Most of the Company’s subsidiaries’ craft labor employees are covered by collective bargaining agreements. The agreements require the subsidiaries to pay specified wages, provide certain benefits and contribute certain amounts to multi-employer pension plans. If a subsidiary withdraws from any of the multi-employer pension plans or if the plans were to otherwise become underfunded, the subsidiary could incur liabilities for additional contributions related to these plans. Although the Company has been informed that the status of some multi-employer pension plans to which its subsidiaries contribute have been classified as “critical” the Company is not currently aware of any potential liabilities related to this issue. See Note 14 — Employee Benefit Plans to the Financial Statements for further information related to the Company’s participation in multi-employer plans.

Litigation and Other Legal Matters

The Company is from time-to-time party to various lawsuits, claims, and other legal proceedings that arise in the ordinary course of business. These actions typically seek, among other things, compensation for alleged personal injury, breach of contract, property damages, punitive damages, civil penalties or other losses, or injunctive or declaratory relief. With respect to all such lawsuits, claims and proceedings, the Company records reserves when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. The Company does not believe that any of these proceedings, separately or in the aggregate, would be expected to have a material adverse effect on the Company’s financial position, results of operation or cash flows.

The Company is routinely subject to other civil claims, litigation and arbitration, and regulatory investigations arising in the ordinary course of our present business as well as in respect of our divested businesses. Some of these claims and litigations include claims related to the Company’s current services and operations, and asbestos-related claims concerning historic operations of a predecessor affiliate. The Company believes that it has strong defenses to these claims as well as insurance coverages that could contribute to any settlement or liability in the event any asbestos-related claim is not resolved in the Company’s favor. These claims have not had a material impact on the Company to date, and the Company believes that the likelihood that a future material adverse outcome will result from these claims is remote. However, if facts and circumstances change in the future, the Company cannot be certain that an adverse outcome of one or more of these claims would not have a material adverse effect on the Company’s financial condition, results of operations or cash flows.

Leases [Abstract]

Lease Obligations

12. Lease Obligations

From time to time, the Company enters into leasing arrangements for real estate, vehicles and construction equipment. In 2017, the Company entered into master leasing arrangements for vehicles and construction equipment. Some of the leases entered into under these agreements met the requirements for capitalization and were recorded as capital leases, while others were treated as operating leases. As of December 31, 2018, the Company had no outstanding commitments to enter into future leases under its master lease agreements.

Capital Leases

The Company leases vehicles and certain equipment under capital leases. The economic substance of the leases is a financing transaction for acquisition of the vehicles and equipment and, accordingly, the leases are included in the balance sheets in property and equipment, net of accumulated depreciation, with a corresponding amount recorded in current portion of capital lease obligations or capital lease obligations, net of current maturities, as appropriate. The capital lease assets are amortized on a straight-line basis over the life of the lease or, if shorter, the life of the leased asset, and included in depreciation expense in the statements of operations. The interest associated with capital leases is included in interest expense in the statements of operations.

As of

December 31, 2018

, the Company had approximately $

2.7

million of capital lease obligations outstanding, $

1.1 million of which was classified as a current liability.

As of

December 31, 2018

and

2017

, $

2.6

million and $

3.7 million, respectively, of leased assets were capitalized in construction equipment, net of accumulated depreciation. Additional information related to property and equipment is provided in Note 6 — Property and Equipment to the Financial Statements.

Operating Leases

The Company leases real estate, construction equipment and office equipment under operating leases with remaining terms ranging from one to eight years.

Rent expense includes lease payments as well as rent on items that are rented under cancellable rental agreements. Total rent expense for the years ended December 31, 2018, 2017 and 2016, was $60.5 million, $44.6 million and $44.9 million, respectively.

The future minimum lease payments required under capital leases, less interest, and future minimum lease payments required under operating leases as of December 31, 2018 were as follows:

(In thousands)	Capital Lease Obligations			Operating Lease Obligations
2019	$	1,185		$	4,829

Certain subsidiaries of the Company have operating leases for facilities from third party companies that are owned, in whole or part, by employees of the subsidiaries. The terms and rental rates of these leases are at market rental rates. As of December 31, 2018, the minimum lease payments required under these leases totaled approximately $2.8 million, which is to be paid over the next 4.5 years.

Stock-Based Compensation

13. Stock-Based Compensation

The Company maintains two equity compensation plans under which stock-based compensation has been granted, the 2017 Long-Term Incentive Plan, (the “LTIP”) and the 2007 Long-Term Incentive Plan (Amended and Restated as of May 1, 2014) (the “2007 LTIP” and, collectively with the LTIP, the “Long-Term Incentive Plans”). Upon the adoption of the LTIP, awards were no longer granted under the 2007 LTIP. The LTIP was approved by our stockholders and provides for grants of (a) incentive stock options qualified as such under U.S. federal income tax laws, (b) stock options that do not qualify as incentive stock options, (c) stock appreciation rights, (d) restricted stock awards, (e) restricted stock units, (f) performance awards, (g) phantom stock, (h) stock bonuses, (i) dividend equivalents, or (j) any combination of such awards. The LTIP permits the granting of up to 900,000 shares to directors, officers and other employees of the Company. Grants of awards to employees are approved by the Compensation Committee of the Board of Directors and grants to independent members of the Board of Directors are approved by the Board of Directors. All awards are made with an exercise price or base price, as the case may be, that is not less than the full fair market value per share on the date of grant. No stock option or stock appreciation right may be exercised more than 10 years from the date of grant.

Shares issued as a result of stock option exercises or stock grants are made available from authorized unissued shares of common stock or treasury stock.

Stock Options

The Company has not awarded any stock options since 2013. Stock options granted to employees or directors vested ratably over a three- or four-year vesting period and were granted with an exercise price equal to the market price of the Company’s stock on the date of grant. The Company used the Black-Scholes-Merton option-pricing model to estimate the fair value of options as of the date of grant. All stock options were fully expensed as of December 31, 2016.

Following is a summary of stock option activity for the three-year period ending December 31, 2018:

	Options			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term		Aggregate Intrinsic Value (in thousands)

Time-Vested Stock Awards

The company grants time-vested stock awards under the LTIP in the form of restricted stock awards, restricted stock units or equity-settled phantom stock. The grant date fair value of the time-vested stock awards is equal to the closing market price of the Company’s common stock on the date of grant. Time-vested stock awards granted under the LTIP to eligible employees in

2018

generally vest ratably, on an annual basis, over three years. Time-vested stock awards granted under the LTIP to non-employee directors in

2018 vest over a one year period.

Following is a summary of time-vested stock awards activity for the three-year period ending December 31, 2018:

	Shares			Per Share Weighted - Average Grant Date Fair Value
Outstanding unvested at January 1, 2016		201,949		$	24.58

Performance Awards

The Company grants performance awards under the LTIP. Under these awards, shares of the Company’s common stock may be earned based on the Company’s performance compared to defined metrics. The number of shares earned under a performance award may vary from zero to 200% of the target shares awarded, based upon the Company’s performance compared to the metrics. The metrics used for the grant are determined by the Compensation Committee of the Board of Directors and may be either based on internal measures such as the Company’s financial performance compared to target or on a market-based metric such as the Company’s stock performance compared to a peer group. Performance awards cliff vest upon attainment of at least the minimum stated performance targets and minimum service requirements and are paid in common shares of the Company’s stock. During 2018, management concluded that it was probable that the minimum performance threshold would not be met for certain performance shares that were granted during 2016 and 2017. As a result, the Company reversed $

0.7

million in stock compensation from previous accruals.

The Company recognizes stock-based compensation expense related to market-based performance awards based on the grant date fair value, which is computed using a Monte Carlo simulation. The Company recognizes stock-based compensation expense related to internal measure-based performance awards based on the grant date fair value, which is the closing price of the Company’s stock on the date of grant. The Company adjusts the stock-based compensation expense related to internal metric-based performance awards according to its determination of the potential achievement of the performance target at each reporting date. The fair value of performance grants are expensed over the service period of approximately 2.8 years.

Following is a summary of performance share award activity for the three-year period ending December 31, 2018:

	Shares			Per Share Weighted- Average Grant Date Fair Value
Outstanding at January 1, 2016		143,608		$	32.68

Stock-based Compensation Expense

The Company recognized stock-based compensation expense of approximately $3.2 million, $4.4 million and $4.7 million for the years ended December 31, 2018, 2017 and 2016, respectively, in selling, general and administrative expenses. As of December 31, 2018, there was approximately $4.4 million of total unrecognized stock-based compensation expense related to awards granted under the Plans. This included $2.6 million of unrecognized compensation cost related to unvested time-vested stock awards expected to be recognized over a remaining weighted average vesting period of approximately 1.6 years and $1.8 million of unrecognized compensation cost related to unvested performance awards, expected to be recognized over a remaining weighted average vesting period of approximately 1.6 years.

Time-vested stock awards granted to non-employee directors in 2018 vest at the end of a one year period and those granted prior to 2018 vest over a period of three years. The grant provision of the time-vested stock awards granted to non-employee directors prior to 2018 contain provisions which call for the vesting of all shares awarded upon a change in control or resignation from the board for any reason except breach of fiduciary duty. As a result of these provisions, the fair value of time-vested stock awards granted to the non-employee directors after 2013 and all directors after 2016, was expensed on the date of the grant.

Employee Benefit Plans

14. Employee Benefit Plans

The Company has a profit sharing and thrift employee benefit plan in effect for all eligible employees. Company contributions under this defined contribution plan are based upon a percentage of income with limitations as defined by the plan. Contributions for the years ended December 31, 2018, 2017 and 2016 amounted to $4.7 million, $3.4 million, and $4.6 million, respectively. The Company also has an employee benefit plan in effect for certain non-union hourly employees. Company contributions under this defined contribution plan are based upon a percentage of income with limitations as defined by the plan. Contributions for the years ended December 31, 2018, 2017 and 2016 amounted to $1.0 million, $0.6 million and $0.6 million, respectively. The Company also has a registered retirement saving plan for certain Canadian employees, contributions to this plan for the years ended December 31, 2018 and 2017 amounted to $0.1 million.

The Company contributes to a number of multiemployer defined benefit pension plans under the terms of collective-bargaining agreements that cover its union-represented employees, who are represented by over 100 local unions. The related collective-bargaining agreements between those organizations and the Company, which specify the rate at which the Company must contribute to the multi-employer defined pension plan, expire at different times between 2019 and 2021.

The risks of participating in these multiemployer defined benefit pension plans are different from single-employer plans in the following aspects:

Assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers.

If a participating employer stops contributing to a plan, the unfunded obligations of the plan may be borne by the remaining participating employers.

If the Company chooses to stop participating in a multiemployer plan, it may be required to pay the plan an amount based on the underfunded status of the plan, referred to as a withdrawal liability.

The amount of additional funds, if any, that the Company may be obligated to contribute to these plans in the future cannot be estimated due to uncertainty of the future levels of work that require the specific use of union employees covered by these plans, as well as the future contribution levels and possible surcharges on contributions applicable to these plans.

The following table summarizes plan information relating to the Company’s participation in multi-employer defined benefit pension plans, including company contributions for the last three years, the status under the Pension Protection Act of 2006, as amended by the Consolidated and Further Continuing Appropriations Act of 2015 (“PPA”) of the plans and whether the plans are subject to a funding improvement or rehabilitation plan, or contribution surcharges. The most recent zone status is for the plan’s year-end indicated in the table. The zone status is based on information that the Company received from the plan, as well as from publicly available information on the U.S. Department of Labor website. The PPA zone status for the plan year ended on December 31, 2018 has not been listed because Forms 5500 were not yet available. Among other factors, plans in the red “critical” zone are generally less than 65 percent funded, plans in the yellow “endangered” zone are between 65 and 80 percent funded, and plans in the green zone are at least 80 percent funded. Also listed in the table below are the Company’s contributions to defined contribution plans.

Information in the table has been presented separately for individually significant plans and in the aggregate for all other plans.

Segment Reporting [Abstract]

Segment Information

15. Segment Information

MYR Group is a holding company of specialty contractors serving electrical utility infrastructure and commercial construction markets in the United States and western Canada. The Company has two reporting segments, each a separate operating segment, which are referred to as T&D and C&I. Performance measurement and resource allocation for the reporting segments are based on many factors. The primary financial measures used to evaluate the segment information are contract revenues and income from operations, excluding general corporate expenses. General corporate expenses include corporate facility and staffing costs, which includes safety costs, professional fees, IT expenses, management fees, and intangible amortization. The accounting policies of the segments are the same as those described in the Summary of Significant Accounting Policies.

Transmission and Distribution:

The T&D segment provides a broad range of services on electric transmission and distribution networks and substation facilities which include design, engineering, procurement, construction, upgrade, maintenance and repair services with a particular focus on construction, maintenance and repair. T&D services include the construction and maintenance of high voltage transmission lines, substations and lower voltage underground and overhead distribution systems. The T&D segment also provides emergency restoration services in response to hurricane, ice or other storm-related damage. T&D customers include investor-owned utilities, cooperatives, private developers, government-funded utilities, independent power producers, independent transmission companies, industrial facility owners and other contractors.

Commercial and Industrial:

The C&I segment provides services including the design, installation, maintenance and repair of commercial and industrial wiring, installation of traffic networks and the installation of bridge, roadway and tunnel lighting. Typical C&I contracts cover electrical contracting services for airports, hospitals, data centers, hotels, stadiums, convention centers, manufacturing plants, processing facilities, waste-water treatment facilities, mining facilities and transportation control and management systems. The C&I segment generally provides electric construction and maintenance services as a subcontractor to general contractors in the C&I industry, but also contracts directly with facility owners.

The information in the following table is derived from the segment’s internal financial reports used for corporate management purposes:

Noncontrolling Interest [Abstract]

Noncontrolling Interests

16. Noncontrolling Interests

On July 2, 2018, through the acquisition of certain assets of the Huen Companies, the Company became the majority controlling interest in a joint venture. As a result, the Company has consolidated the carrying value of the joint ventures’ assets and liabilities and results of operations in the Company’s consolidated financial statements. The equity owned by the other joint venture partners has been recorded as noncontrolling interests in the Company’s consolidated balance sheets, and their portions, if material, of net income and other comprehensive income shown as net income or other comprehensive income attributable to noncontrolling interests in the Company’s consolidated statements of operations and other comprehensive income. Additionally the joint venture associated with the Company’s noncontrolling interests is a partnership, and consequently, the tax effect of only the Company’s share of the joint venture income is recognized by the Company.

The acquired joint venture made no distributions to its partners, and the Company made no capital contributions to the joint venture during the year ended December 31, 2018. Additionally, there have been no changes in ownership during the year ended December 31, 2018. The project is expected to be completed in 2019. The balance of the Company’s noncontrolling interest consists of the preliminary fair value of noncontrolling interest acquired on July 2, 2018 with the Huen Companies. Net income attributable to the noncontrolling interest, subsequent to the acquisition through December 31, 2018, was $0.2 million.

All of the Company’s non-participating unvested restricted shares were included in the computation of weighted average dilutive securities. The following table summarizes the shares of common stock underlying the Company’s unvested stock options and performance awards that were excluded from the calculation of dilutive securities:
