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. 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 Company’s consolidated balance sheets. If an investment in a joint venture contains a recourse or unfunded commitments to provide additional equity, distributions and/or losses in excess of the investment a liability is recorded in other current liabilities on the Company's 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 17—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 Company’s consolidated statements of operations. For the year ended December 31, 2019, the Company recorded foreign currency gains of approximately $0.1 million. 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 Company’s consolidated statements of comprehensive income. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("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. As of December 31, 2019 and 2018, the Company recognized revenues of $35.9 million and $3.4 million, respectively, 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. These aggregate amounts, which were included in "Contract assets" in the accompanying consolidated balance sheets, represent the Company's estimates of additional contract revenues that were earned and probable of collection, however, the amount ultimately realized could be significantly higher or lower than the estimated amount. 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, 2019, changes in estimates pertaining to certain projects decreased consolidated gross margin by 0.8%, which resulted in decreases in operating income of $11.7 million, net income attributable to MYR Group Inc. of $7.5 million and diluted earnings per common share attributable to MYR Group Inc. of $0.45. The estimates are reviewed and revised quarterly, as needed. 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. 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. Advertising Advertising costs are expensed when incurred. Advertising costs, included in selling, general and administrative expenses, were $0.8 million for the year ended December 31, 2019, and $0.7 million for the years ended December 31, 2018 and 2017, 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 on the Company's 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. 2016‑09, 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, 2019 and 2018, 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 on the Company’s consolidated balance sheets and are reflected as a financing activity on the Company’s 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, 2019 and 2018. The Company’s consolidated balance sheets present contract liabilities that 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 On January 1, 2019, the Company adopted ASU No. 2016-02, Leases (Topic 842) using the modified retrospective method. Under this guidance, the net present value of future lease payments are recorded as right-of-use assets and liabilities. In addition, the Company elected the 'package of practical expedients' permitted under the transition guidance within the new standard, which among other things, allowed the Company to carry forward the historical lease classification. In addition, the Company elected not to utilize the hindsight practical expedient to determine the lease term for existing leases. The Company elected the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, the Company did not recognize right-of-use assets or lease liabilities, including not recognizing right-of-use assets or lease liabilities for existing short-term leases of those assets in transition. The Company also elected the practical expedient to not separate lease and non-lease components for our real estate and vehicle leases. The Company enters into non-cancelable leases for some of our facility, vehicle and equipment needs. These leases allow the Company to conserve cash by paying a monthly lease rental fee for the use of facilities, vehicles and equipment rather than purchasing them. The Company’s leases have remaining terms ranging from one to seven years, some of which may include options to extend the leases for up to five years, and some of which may include options to terminate the leases within one year. Currently, all the Company’s leases contain fixed payment terms. The Company may decide to cancel or terminate a lease before the end of its term, in which case we are typically liable to the lessor for the remaining lease payments under the term of the lease. Additionally, all of the Company’s month-to-month leases are cancelable, by the Company or the lessor, at any time and are not included in our right-of-use asset or liability. As of December 31, 2019, the Company had several leases with residual value guarantees, due to the acquisition of CSI. The total amount probable of being owed of residual leases guarantees is not significant. Typically, the Company has purchase options on the equipment underlying its long-term leases and many of its short-term rental arrangements. The Company may exercise some of these purchase options when the need for equipment is on-going and the purchase option price is attractive. 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 842-10-25. Leases are accounted for as operating or finance leases, depending on the terms of the lease. Finance Leases. The Company leases some vehicles and certain equipment under finance leases. The economic substance of the leases is a financing transaction for acquisition of the vehicles and equipment. Accordingly, the right-of-use assets for these leases are included on the Company’s consolidated balance sheets in property and equipment, net of accumulated depreciation, with a corresponding amount recorded in current portion of finance lease obligations or finance lease obligations, net of current maturities, as appropriate. The finance lease assets are amortized over the life of the lease or, if shorter, the life of the leased asset, on a straight-line basis and included in depreciation expense. The financing component associated with finance lease obligations is included in interest expense. Generally, for the Company's finance leases an implicit rate to calculate present value is provided in the lease agreement, however if a rate in not provided the Company determines this rate by estimating the Company's incremental borrowing rate, utilizing the borrowing rates associated with the Company's various debt instruments. Operating Right-of-Use Leases. Operating right-of-use leases are included in operating lease right-of-use assets, current portion of operating lease obligations and operating lease obligations, net of current maturities on the Company’s consolidated balance sheets, as appropriate. Operating lease right-of-use assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the Company’s leases do not provide an implicit rate to calculate present value, the Company determines this rate by estimating the Company’s incremental borrowing rate, utilizing the borrowing rates associated with the Company’s various debt instruments. The operating lease right-of-use asset also includes any lease payments made and initial direct costs incurred and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. Prior to January, 2019 the Company accounted for its leases in accordance with Leases (Topic 840). Leases with characteristics of operating leases were expensed on a straight-line basis over the life of the lease on the Company’s consolidated statements of operations. Leases with the characteristics of capital leases were recorded at fair value on the Company’s consolidated balance sheets. The asset portion was included in property and equipment on the Company’s consolidated balance sheets and was amortized as depreciation expense on the Company’s consolidated statements of operations. The liability portion was included on the Company’s consolidated balance sheets as current and long term portions of capital leases. These liabilities were amortized as interest expense and lease expense on the Company’s consolidated statements of operations. 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 on the Company’s 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 2019 and 2017, 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 30.8%, 32.9%, and 40.4% of consolidated revenues for the years ended December 31, 2019, 2018 and 2017, respectively. For the years ended December 31, 2019 and 2018, no single customer accounted for more than 10.0% of annual revenues. For the year ended December 31, 2017, one T&D customer accounted for 10.7% of our 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, 2019 and 2018, none of the Company's 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, 2019, approximately 90% 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 February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The amendments under this pronouncement changed the way all leases with durations in excess of one year are treated. Under this guidance, lessees are required to recognize virtually all leases on the balance sheet as a right-of-use asset and an associated finance lease liability or operating 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 finance leases or operating leases. Finance lease liabilities, which contain provisions similar to capitalized leases under the prior accounting standards, are amortized as amortization expense and interest expense in the statement of operations. Operating lease liabilities and right-of-use assets are adjusted to result in a single straight-line lease expense over the life of the lease. On January 1, 2019, the Company adopted ASU No. 2016-02, Leases (Topic 842) using the modified retrospective method. The modified retrospective basis provides a method for recording existing leases at adoption and in comparative periods that approximates the results of a full retrospective approach using the cumulative-effect approach for recording the transition adjustment as of the effective date. Financial results reported in prior periods are unchanged. See Note 4–Lease Obligations for further information related to the Company’s accounting policy and transition disclosures associated with the adoption of this pronouncement. 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 June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments, which introduced an expected credit loss methodology for the measurement and recognition of credit losses on most financial instruments, including trade receivables and off-balance sheet credit exposures. Under this guidance, an entity is required to consider a broader range of information to estimate expected credit losses, which may result in earlier recognition of losses. This ASU also requires disclosure of information regarding how a company developed its allowance, including changes in the factors that influenced management’s estimate of expected credit losses and the reasons for those changes. The ASU and its related clarifying updates are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted. The adoption of this standard will be through a cumulative-effect adjustment to retained earnings as of the effective date. Based on our historical experience, the Company does not expect that this pronouncement will have a significant impact in its financial statements or on the estimate of the allowance for uncollectable accounts. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements for Level 1, Level 2 and Level 3 instruments in the fair value hierarchy. The guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted for any eliminated or modified disclosures. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements or disclosures. In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance to promote consistent application among reporting entities. The guidance is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years, with early adoption permitted. Upon adoption, the Company must apply certain aspects of this standard retrospectively for all periods presented while other aspects are applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. The Company is evaluating the impact this update will have on its financial statements.

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.

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 Company’s consolidated balance sheets. If an investment in a joint venture contains a recourse or unfunded commitments to provide additional equity, distributions and/or losses in excess of the investment a liability is recorded in other current liabilities on the Company's 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 17—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 Company’s consolidated statements of operations. For the year ended December 31, 2019, the Company recorded foreign currency gains of approximately $0.1 million. 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 Company’s consolidated statements of comprehensive income.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("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.

As of December 31, 2019 and 2018, the Company recognized revenues of $35.9 million and $3.4 million, respectively, 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. These aggregate amounts, which were included in "Contract assets" in the accompanying consolidated balance sheets, represent the Company's estimates of additional contract revenues that were earned and probable of collection, however, the amount ultimately realized could be significantly higher or lower than the estimated amount.

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, 2019, changes in estimates pertaining to certain projects decreased consolidated gross margin by 0.8%, which resulted in decreases in operating income of $11.7 million, net income attributable to MYR Group Inc. of $7.5 million and diluted earnings per common share attributable to MYR Group Inc. of $0.45. The estimates are reviewed and revised quarterly, as needed. 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. 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.

Advertising

Advertising costs are expensed when incurred. Advertising costs, included in selling, general and administrative expenses, were $0.8 million for the year ended December 31, 2019, and $0.7 million for the years ended December 31, 2018 and 2017, 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 on the Company's 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. 2016‑09, 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, 2019 and 2018, 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 on the Company’s consolidated balance sheets and are reflected as a financing activity on the Company’s 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, 2019 and 2018.

The Company’s consolidated balance sheets present contract liabilities that 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

On January 1, 2019, the Company adopted ASU No. 2016-02, Leases (Topic 842) using the modified retrospective method. Under this guidance, the net present value of future lease payments are recorded as right-of-use assets and liabilities. In addition, the Company elected the 'package of practical expedients' permitted under the transition guidance within the new standard, which among other things, allowed the Company to carry forward the historical lease classification. In addition, the Company elected not to utilize the hindsight practical expedient to determine the lease term for existing leases. The Company elected the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, the Company did not recognize right-of-use assets or lease liabilities, including not recognizing right-of-use assets or lease liabilities for existing short-term leases of those assets in transition. The Company also elected the practical expedient to not separate lease and non-lease components for our real estate and vehicle leases.

The Company enters into non-cancelable leases for some of our facility, vehicle and equipment needs. These leases allow the Company to conserve cash by paying a monthly lease rental fee for the use of facilities, vehicles and equipment rather than purchasing them. The Company’s leases have remaining terms ranging from one to seven years, some of which may include options to extend the leases for up to five years, and some of which may include options to terminate the leases within one year. Currently, all the Company’s leases contain fixed payment terms. The Company may decide to cancel or terminate a lease before the end of its term, in which case we are typically liable to the lessor for the remaining lease payments under the term of the lease. Additionally, all of the Company’s month-to-month leases are cancelable, by the Company or the lessor, at any time and are not included in our right-of-use asset or liability. As of December 31, 2019, the Company had several leases with residual value guarantees, due to the acquisition of CSI. The total amount probable of being owed of residual leases guarantees is not significant. Typically, the Company has purchase options on the equipment underlying its long-term leases and many of its short-term rental arrangements. The Company may exercise some of these purchase options when the need for equipment is on-going and the purchase option price is attractive. 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 842-10-25. Leases are accounted for as operating or finance leases, depending on the terms of the lease.

Finance Leases. The Company leases some vehicles and certain equipment under finance leases. The economic substance of the leases is a financing transaction for acquisition of the vehicles and equipment. Accordingly, the right-of-use assets for these leases are included on the Company’s consolidated balance sheets in property and equipment, net of accumulated depreciation, with a corresponding amount recorded in current portion of finance lease obligations or finance lease obligations, net of current maturities, as appropriate. The finance lease assets are amortized over the life of the lease or, if shorter, the life of the leased asset, on a straight-line basis and included in depreciation expense. The financing component associated with finance lease obligations is included in interest expense. Generally, for the Company's finance leases an implicit rate to calculate present value is provided in the lease agreement, however if a rate in not provided the Company determines this rate by estimating the Company's incremental borrowing rate, utilizing the borrowing rates associated with the Company's various debt instruments.

Operating Right-of-Use Leases. Operating right-of-use leases are included in operating lease right-of-use assets, current portion of operating lease obligations and operating lease obligations, net of current maturities on the Company’s consolidated balance sheets, as appropriate. Operating lease right-of-use assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the Company’s leases do not provide an implicit rate to calculate present value, the Company determines this rate by estimating the Company’s incremental borrowing rate, utilizing the borrowing rates associated with the Company’s various debt instruments. The operating lease right-of-use asset also includes any lease payments made and initial direct costs incurred and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.

Prior to January, 2019 the Company accounted for its leases in accordance with Leases (Topic 840). Leases with characteristics of operating leases were expensed on a straight-line basis over the life of the lease on the Company’s consolidated statements of operations. Leases with the characteristics of capital leases were recorded at fair value on the Company’s consolidated balance sheets. The asset portion was included in property and equipment on the Company’s consolidated balance sheets and was amortized as depreciation expense on the Company’s consolidated statements of operations. The liability portion was included on the Company’s consolidated balance sheets as current and long term portions of capital leases. These liabilities were amortized as interest expense and lease expense on the Company’s consolidated statements of operations.

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 on the Company’s 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 2019 and 2017, 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 30.8%, 32.9%, and 40.4% of consolidated revenues for the years ended December 31, 2019, 2018 and 2017, respectively. For the years ended December 31, 2019 and 2018, no single customer accounted for more than 10.0% of annual revenues. For the year ended December 31, 2017, one T&D customer accounted for 10.7% of our 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, 2019 and 2018, none of the Company's 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, 2019, approximately 90% 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 February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The amendments under this pronouncement changed the way all leases with durations in excess of one year are treated. Under this guidance, lessees are required to recognize virtually all leases on the balance sheet as a right-of-use asset and an associated finance lease liability or operating 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 finance leases or operating leases. Finance lease liabilities, which contain provisions similar to capitalized leases under the prior accounting standards, are amortized as amortization expense and interest expense in the statement of operations. Operating lease liabilities and right-of-use assets are adjusted to result in a single straight-line lease expense over the life of the lease. On January 1, 2019, the Company adopted ASU No. 2016-02, Leases (Topic 842) using the modified retrospective method. The modified retrospective basis provides a method for recording existing leases at adoption and in comparative periods that approximates the results of a full retrospective approach using the cumulative-effect approach for recording the transition adjustment as of the effective date. Financial results reported in prior periods are unchanged. See Note 4–Lease Obligations for further information related to the Company’s accounting policy and transition disclosures associated with the adoption of this pronouncement.

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 June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments, which introduced an expected credit loss methodology for the measurement and recognition of credit losses on most financial instruments, including trade receivables and off-balance sheet credit exposures. Under this guidance, an entity is required to consider a broader range of information to estimate expected credit losses, which may result in earlier recognition of losses. This ASU also requires disclosure of information regarding how a company developed its allowance, including changes in the factors that influenced management’s estimate of expected credit losses and the reasons for those changes. The ASU and its related clarifying updates are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted. The adoption of this standard will be through a cumulative-effect adjustment to retained earnings as of the effective date. Based on our historical experience, the Company does not expect that this pronouncement will have a significant impact in its financial statements or on the estimate of the allowance for uncollectable accounts.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements for Level 1, Level 2 and Level 3 instruments in the fair value hierarchy. The guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted for any eliminated or modified disclosures. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements or disclosures.

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance to promote consistent application among reporting entities. The guidance is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years, with early adoption permitted. Upon adoption, the Company must apply certain aspects of this standard retrospectively for all periods presented while other aspects are applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. The Company is evaluating the impact this update will have on its financial statements.
