Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	ORGANIZATION Installed Building Products (“IBP”), a Delaware corporation formed on October 28, 2011, and its wholly-owned subsidiaries (collectively referred to as the “Company,” and “we,” “us” and “our”) primarily install insulation, waterproofing, fire-stopping, fireproofing, garage doors, rain gutters, window blinds, shower doors, closet shelving and mirrors and other products for residential and commercial builders located in the continental United States. The Company operates in over 210 locations and its corporate office is located in Columbus, Ohio. We have one operating segment and a single reportable segment. The vast majority of our sales are derived from the service-based installation of various products in the residential new construction, repair and remodel and commercial construction end markets from our national network of branch locations. Each of our branches has the capacity to serve all of our end markets. See Note 3, Revenue Recognition, for information on our revenues by product and end market.

Significant Accounting Policies

Significant Accounting Policies	12 Months Ended

Accounting Policies [Abstract]
Significant Accounting Policies	SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Principles of Consolidation We prepare our consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The accompanying consolidated financial statements include all of our wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated. Use of Estimates Preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, judgements and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Management believes the accounting estimates are appropriate and reasonably determined; however, due to the inherent uncertainties in making these estimates, actual amounts could differ from such estimates. Cash and Cash Equivalents We consider all highly-liquid investments purchased with original term to maturity of three months or less to be cash equivalents. Substantially all cash is held in banks providing FDIC coverage of $0.25 million per depositor. Revenue and Cost Recognition Revenue is measured according to Accounting Standards Codification ("ASC") 606, “Revenue from Contracts with Customers.” Our revenues are derived primarily through contracts with customers whereby we install insulation and other complementary building products and are recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. An insignificant portion of our sales, primarily retail and distribution sales, is accounted for on a point-in-time basis when the sale occurs and the risk of loss transfers to the customer, adjusted accordingly for any return provisions and net of any sales taxes. We do offer assurance-type warranties on certain of our installed products and services that do not represent a separate performance obligation and, as such, do not impact the timing or extent of revenue recognition. For contracts that are not complete at the reporting date, we recognize revenue over time utilizing a cost-to-cost input method as we believe this represents the best measure of when goods and services are transferred to the customer. When this method is used, we estimate the costs to complete individual contracts and record as revenue that portion of the total contract price that is considered complete based on the relationship of costs incurred to date to total anticipated costs. Under the cost-to-cost method, the use of estimated costs to complete each contract is a significant variable in the process of determining recognized revenue, requires judgment and can change throughout the duration of a contract due to contract modifications and other factors impacting job completion. The costs of earned revenue include all direct material and labor costs and those indirect costs related to contract performance, such as indirect labor, supplies, tools and repairs. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Our long-term contracts can be subject to modification to account for changes in contract specifications and requirements. We consider contract modifications to exist when the modification either creates new, or changes the existing, enforceable rights and obligations. Most of our contract modifications are for goods or services that are not distinct from the existing contract due to the significant integration service provided in the context of the contract and are accounted for as if they were part of that existing contract. The effect of a contract modification on the transaction price and our measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis. Payment terms typically do not exceed 30 days for short-term contracts and typically do not exceed 60 days for long-term contracts with customers. All contracts are billed either contractually or as work is performed. Billing on our long-term contracts occurs primarily on a monthly basis throughout the contract period whereby we submit invoices for customer payment based on actual or estimated costs incurred during the billing period. On certain of our long-term contracts the customer may withhold payment on an invoice equal to a percentage of the invoice amount, which will be subsequently paid after satisfactory completion of each installation project. This amount is referred to as retainage and is common practice in the construction industry, as it allows for customers to ensure the quality of the service performed prior to full payment. Retainage receivables are classified as current or long-term assets based on the expected time to project completion. See "Accounts Receivable" below for further discussion of our retainage receivables. We generally expense sales commissions and other incremental costs of obtaining a contract when incurred because the amortization period is usually one year or less. Sales commissions are recorded within selling expenses on the Consolidated Statements of Operations and Comprehensive Income. We do not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less. Derivative Instruments and Hedging Activities We record all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the earnings effect of the hedged forecasted transactions in a cash flow hedge. We may enter into derivative contracts that are intended to economically hedge certain of our risks, even though hedge accounting does not apply or we elect not to apply hedge accounting. See Note 11, Derivatives and Hedging Activities, for additional information on our accounting policy for derivative instruments and hedging activities. Business Combinations The purchase price for business combinations is allocated to the estimated fair values of acquired tangible and intangible assets, including goodwill and assumed liabilities, where applicable. Additionally, we recognize customer relationships, trademarks and trade names, backlog and non-competition agreements as identifiable intangible assets. These assets are recorded at fair value as of the transaction date. The fair value of these intangibles is determined using either the income approach or the market approach using current industry information which involves significant unobservable inputs (Level 3 inputs). These inputs include projected sales, margin and tax rate. At times, the total purchase price for a business combination could be less than the estimated fair values of acquired tangible and intangible assets. In these cases, we record a gain on bargain purchase within other expenses in the Consolidated Statements of Operations and Comprehensive Income rather than goodwill in accordance with U.S. GAAP. Accounts Receivable We account for trade receivables based on amounts billed to customers. Past due receivables are determined based on contractual terms. We do not accrue interest on any of our trade receivables. Retainage receivables represent the amount retained by our customers to ensure the quality of the installation and is received after satisfactory completion of each installation project. Management regularly reviews aging of retainage receivables and changes in payment trends and records an allowance when collection of amounts due are considered at risk. Amounts retained by project owners under construction contracts and included in accounts receivable were $40.5 million and $41.7 million as of December 31, 2021 and 2020, respectively. In addition, as of December 31, 2021, $0.5 million of retainage receivables were recorded in other non-current assets. Credit losses are measured according to ASC 326, “Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments.” We consider forward-looking information to estimate expected credit losses for financial instruments, including trade receivables, retainage receivables and contract assets (unbilled receivables). Our expected loss allowance methodology for accounts receivable is developed using historical losses, current economic conditions and future market forecasts. We also perform ongoing evaluations of our existing and potential customer’s creditworthiness. To date, the COVID-19 pandemic has not yet had a material impact on the collectability of our existing trade receivables. See Note 4, Credit Losses, for additional information. Concentration of Credit Risk Credit risk is our risk of financial loss from the non-performance of a contractual obligation on the part of our counterparty. Such risk arises principally from our receivables from customers and cash and bank balances. Substantially all of our trade accounts receivable are from entities engaged in residential and commercial construction. We perform periodic credit evaluations of our customers’ financial condition. The general credit risk of our counterparties is not considered to be significant. In addition, no individual customer made up more than 3% of accounts receivable or 5% of net revenue for the years ended December 31, 2021, 2020 and 2019. Inventories Inventories consist of insulation, waterproofing materials, fireproofing and fire-stopping materials, garage doors, rain gutters, window blinds, shower doors, mirrors, closet shelving and other products. We value inventory at each balance sheet date to ensure that it is carried at the lower of cost or net realizable value with cost determined using the first-in, first-out (“FIFO”) method. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable cost of completion, disposal and transportation. As of December 31, 2021 and 2020, substantially all inventory was finished goods. Inventory provisions are recorded to reduce inventory to the lower of cost or net realizable value for obsolete or slow moving inventory based on assumptions about future demand and marketability of products, the impact of new product introductions, inventory levels and turns, product spoilage, and specific identification of items such as product discontinuance, engineering/material changes, or regulatory-related changes. Property and Equipment Property and equipment are stated at cost, less accumulated depreciation. We provide for depreciation and amortization of property and equipment using the straight-line method over the expected useful lives of the assets. Expected useful lives of property and equipment vary but generally are the shorter of lease life or five years for vehicles and leasehold improvements, three Major renewals and improvements are capitalized. Maintenance, repairs and minor renewals are expensed as incurred. When assets are retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is recorded. Goodwill Goodwill results from business combinations and represents the excess of the purchase price over the fair value of acquired tangible assets and liabilities and identifiable intangible assets. Annually, on October 1, or if conditions indicate an earlier review is necessary, we perform a one-step quantitative test to determine if it is more likely than not that the fair value of the reporting unit is less than its carrying amount. The estimate of the reporting unit’s fair value is determined by weighting a discounted cash flow model and a market-related model using current industry information that involve significant unobservable inputs (Level 3 inputs). In determining the estimated future cash flow, we consider and apply certain estimates and judgments, including current and projected future levels of income based on management’s plans, business trends, prospects, market and economic conditions and market-participant considerations. An impairment charge is recognized for the amount by which the carrying value exceeds the reporting unit's fair value, not to exceed the total amount of goodwill allocated to the reporting unit. Impairment of Other Intangible and Long-Lived Assets Other intangible assets consist of customer relationships, backlog, non-competition agreements and business trademarks and trade names. Amortization of finite lived intangible assets is recorded to reflect the pattern of economic benefits based on projected revenues over their respective estimated useful lives (customer relationships – eight one two We review long-lived assets and intangible assets whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. An impairment loss is recognized when estimated future cash flows expected to result from the use of an asset and its eventual disposition are less than its carrying amount. When impairment is identified, the carrying amount of the asset is reduced to its estimated fair value. Assets to be disposed of are recorded at the lower of net book value or fair net realizable value less cost to sell at the date management commits to a plan of disposal. There was no impairment loss for the years ended December 31, 2021, 2020, and 2019. Other Liabilities Our workers’ compensation insurance program, for a significant portion of our business, is considered a high deductible program whereby we are responsible for the cost of claims under approximately $0.8 million. Our general liability insurance program is considered a high retention program whereby we are responsible for the cost of claims up to approximately $5.0 million, subject to an aggregate cap of $10.0 million. Our vehicle liability insurance program is considered a high deductible program whereby we are responsible for the cost of claims under approximately $1.0 million. In each case, if we do not pay these claims, our insurance carriers are required to make these payments to the claimants on our behalf. The liabilities represent our best estimate of our costs, using generally accepted actuarial reserving methods, of the ultimate obligations for reported claims plus those incurred but not reported for all claims incurred through December 31, 2021 and 2020. We establish case reserves for reported claims using case-basis evaluation of the underlying claims data and we update as information becomes known. We regularly monitor the potential for changes in estimates, evaluate our insurance accruals and adjust our recorded provisions. The assumptions underlying the ultimate costs of existing claim losses are subject to a high degree of unpredictability, which can affect the liability recorded for such claims. For example, variability in inflation rates of health care costs inherent in workers’ compensation claims can affect the ultimate costs. Similarly, changes in legal trends and interpretations, as well as a change in the nature and method of how claims are settled, can affect ultimate costs. Our estimates of liabilities incurred do not anticipate significant changes in historical trends for these variables and any changes could have a considerable effect on future claim costs and currently recorded liabilities. We carry insurance for a number of risks, including, but not limited to, workers’ compensation, general liability, vehicle liability, property and our obligation for employee-related health care benefits. Liabilities relating to claims associated with these risks are estimated by considering historical claims experience, including frequency, severity, demographic factors and other actuarial assumptions. In estimating our liability for such claims, we periodically analyze our historical trends, including loss development, and apply appropriate loss development factors to the incurred costs associated with the claims with the assistance of external actuarial consultants. While we do not expect the amounts ultimately paid to differ significantly from our estimates, our reserves and corresponding expenses could be affected if future claim experience differs significantly from historical trends and actuarial assumptions. Advertising Costs Advertising costs are generally expensed as incurred. Advertising expense was approximately $4.6 million for the year ended December 31, 2021, and $3.9 million for both the years ended December 31, 2020 and 2019, respectively, and is included in selling expense on the Consolidated Statements of Operations and Comprehensive Income. Deferred Financing Costs Deferred financing costs and debt issuance costs combined, totaling $11.4 million and $7.0 million, net of accumulated amortization as of December 31, 2021 and 2020, respectively, are amortized over the term of the related debt on a straight-line basis which approximates the effective interest method. The deferred financing costs are included in other non-current assets while the debt issuance costs are included in long-term debt on the Consolidated Balance Sheets as of December 31, 2021 and 2020, respectively. The related amortization expense of these costs combined was $1.4 million, $1.3 million and $1.2 million and is included in interest expense, net on the Consolidated Statements of Operations and Comprehensive Income for the years ended December 31, 2021, 2020 and 2019, respectively. We wrote off $0.2 million and $3.3 million in previously capitalized loan costs during the years ended December 31, 2021 and 2019, respectively. In addition, we expensed loan costs of approximately $1.6 million and $0.4 million for the years ended December 31, 2021 and 2019, respectively, associated with our credit facilities because they did not meet the requirements for capitalization. We had no such write offs or expenses during the year ended December 31, 2020. These amounts are included in interest expense, net on the Consolidated Statements of Operations and Comprehensive Income. We also had $7.5 million in new costs associated with the debt-related financing transactions incurred during the year ended December 31, 2021. The deferred financing costs are included in other non-current assets while the debt issuance costs are included in long-term debt on the Consolidated Balance Sheets. These costs are amortized over the term of the related debt on a straight-line basis which approximates the effective interest method. For additional information on our debt instruments, see Note 8, Long-Term Debt. Leases Leases are measure according to ASC 842, “Leases,” which requires substantially all leases, with the exception of leases with a term of one year or less, to be recorded as a lease liability measured as the present value of the future lease payments with a corresponding right-of-use asset. ASC 842 also requires disclosures designed to give financial statement users information on the amount, timing and uncertainty of cash flows. We determine if an arrangement is a lease at inception. Most of our operating leases do not provide an implicit rate so we use our incremental borrowing rate based on the information available at the commencement date to determine the present value of future payments. Leases with an initial term of 12 months or less are not recorded on the balance sheet as we recognize lease expense for these leases on a straight-line basis over the lease term. We elect to not separate lease components from non-lease components for all fixed payments, and we exclude variable lease payments in the measurement of right-of-use assets and lease obligations. Most lease agreements include one or more renewal options, all of which are at our sole discretion. Generally, future renewal options that have not been executed as of the balance sheet date are excluded from right-of-use assets and related lease liabilities. Certain leases also include options to purchase the leased property. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. Some of our vehicle lease agreements include provisions for residual value guarantees and any expected payment is included in our lease liability. Share-Based Compensation Our share-based compensation program is designed to attract and retain employees while also aligning employees’ interests with the interests of our stockholders. Restricted stock awards are periodically granted to certain employees, officers and non-employee members of our board of directors under the stockholder-approved 2014 Omnibus Incentive Plan. Certain of our stock awards are deemed to be equity-based with a service condition and do not contain a market or performance condition with the exception of performance-based awards granted to certain officers and performance-based stock units. Fair value of the non-performance-based awards to employees and officers is measured at the grant date and amortized to expense over the vesting period of the awards using the straight-line attribution method for all service-based awards with a graded vesting feature. This fair value is reduced by assumed forfeitures and adjusted for actual forfeitures until vesting. We also issue performance-based stock awards to certain officers under our 2014 Omnibus Incentive Plan. The performance-based compensation expense is recorded over the requisite service period using the graded-vesting method for the entire award. Performance-based stock awards are accounted for at fair value at date of grant. We also periodically grant performance-based stock units to certain employees under the stockholder-approved 2014 Omnibus Incentive Plan. These units convert to shares upon meeting time- and performance-based requirements. Compensation expense for performance-based stock units is recorded based on an assessment each reporting period of the probability that certain performance goals will be met during the contingent vesting period. If performance goals are not probable to occur, no compensation expense will be recognized. If performance goals that were previously deemed probable are not or are not expected to be met, the previously recognized compensation cost related to such performance goals will be reversed. Employees and officers are subject to tax at the vesting date based on the market price of the shares on that date, or on the grant date if an election is made. Income Taxes We account for income taxes using the asset and liability method. Under this method, the amount of taxes currently payable or refundable are accrued and deferred tax assets and liabilities are recognized for the estimated future tax consequences of temporary differences that currently exist between the tax basis and financial reporting basis of our assets and liabilities. Valuation allowances are established against deferred tax assets when it is more likely than not that the realization of those deferred tax assets will not occur. In evaluating our ability to recover our deferred tax assets within the jurisdiction from which they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, the ability to produce future taxable income, prudent and feasible tax planning strategies and recent financial operations. In projecting future taxable income, we factor in historical results and changes in accounting policies and incorporate assumptions, including the amount of future federal and state pretax operating income, the reversal of temporary differences and the implementation of feasible and prudent tax planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates we use to manage the underlying businesses. Deferred tax assets and liabilities are measured using the enacted tax rates in effect in the years when those temporary differences are expected to reverse. The effect on deferred taxes from a change in tax rate is recognized through operations in the period that includes the enactment date of the change. Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the future. A tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. Income tax positions must meet a more likely than not recognition threshold to be recognized. We recognize tax liabilities for uncertain tax positions and adjust these liabilities when our judgment changes as a result of the evaluation of new information not previously available. Liabilities related to uncertain tax positions are recorded in other long-term liabilities on the Consolidated Balance Sheets. Due to the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from the current estimate of the tax liabilities. These differences will be reflected as increases or decreases to income tax expense and the effective tax rate in the period in which the new information becomes available. Interest and penalties related to unrecognized tax benefits are recognized within income tax expense in the Consolidated Statements of Operations and Comprehensive Income. Accrued interest and penalties are recognized in other current liabilities on the Consolidated Balance Sheets. Our income tax expense, deferred tax assets and liabilities and reserves for unrecognized tax benefits reflect management’s best assessment of estimated future taxes to be paid. We are subject to income taxes in the United States, which includes numerous state and local jurisdictions. Significant judgments and estimates are required in determining the income tax expense, deferred tax assets and liabilities and the reserve for unrecognized tax benefits.

Our contract assets are recorded in other current assets in our Consolidated Balance Sheets. Our contract liabilities consist of customer deposits and billings in excess of revenue recognized, based on costs incurred and are included in other current liabilities in our Consolidated Balance Sheets. Contract assets and liabilities related to our uncompleted contracts and customer deposits were as follows (in thousands): As of December 31, 2021 2020 Contract assets $ 32,679 $ 24,334 Contract liabilities (14,153) (8,965) Uncompleted contracts were as follows (in thousands): As of December 31, 2021 2020 Costs incurred on uncompleted contracts $ 206,050 $ 169,544 Estimated earnings 106,163 90,737 Total 312,213 260,281 Less: Billings to date 285,978 240,665 Net under billings $ 26,235 $ 19,616 Net under billings were as follows (in thousands): As of December 31, 2021 2020 Costs and estimated earnings in excess of billings on uncompleted contracts (contract assets) $ 32,679 $ 24,334 Billings in excess of costs and estimated earnings on uncompleted contracts (contract liabilities) (6,444) (4,718) Net under billings $ 26,235 $ 19,616 The difference between contract assets and contract liabilities as of December 31, 2021 compared to December 31, 2020 is primarily the result of timing differences between our performance of obligations under contracts and customer payments and billings. During the year ended December 31, 2021, we recognized $8.7 million of revenue that was included in the contract liability balance at December 31, 2020. We did not recognize any impairment losses on our receivables and contract assets during the years ended December 31, 2021 and 2020. Remaining performance obligations represent the transaction price of contracts for which work has not been performed and excludes unexercised contract options and potential modifications. As of December 31, 2021, the aggregate amount of the transaction price allocated to remaining uncompleted contracts was $143.2 million. We expect to satisfy remaining performance obligations and recognize revenue on substantially all of these uncompleted contracts over the next 18 months.

Credit Loss [Abstract]
Credit Losses	CREDIT LOSSESOn January 1, 2020 we adopted ASU 2016-13, “Financial Instruments – Credit Losses (ASC 326): Measurement of Credit Losses on Financial Instruments” under the modified retrospective approach. ASC 326 replaces the incurred loss impairment model with an expected credit loss impairment model for financial instruments, including trade receivables, retainage receivables and contract assets (unbilled receivables). Results for reporting periods beginning after January 1, 2020 are presented under ASC 326, while prior period amounts are not adjusted. The amendment requires entities to consider forward-looking information to estimate expected credit losses, resulting in earlier recognition of losses for receivables that are current or not yet due, which were not considered under the previous accounting guidance. Upon adoption of ASC 326, we recorded a cumulative effect adjustment to retained earnings of $1.2 million, net of $0.4 million of income taxes, on the opening consolidated balance sheet as of January 1, 2020. The adoption of the credit loss standard had no impact to cash from or used in operating, financing or investing activities on our consolidated cash flow statements. Changes in our allowance for credit losses were as follows (in thousands): January 1, 2019 $ 5,085 Current period provision 4,312 Recoveries collected and additions 1,269 Amounts written off (3,788) December 31, 2019 $ 6,878 Cumulative effect of change in accounting principle 1,600 Current period provision 4,444 Recoveries collected and additions 503 Amounts written off (4,636) December 31, 2020 $ 8,789 Current period provision 2,227 Recoveries collected and additions 574 Amounts written off (2,873) December 31, 2021 $ 8,717

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangibles	GOODWILL AND INTANGIBLES The homebuilding industry quickly rebounded from the immediate effects of the COVID-19 pandemic but continues to be affected by other pandemic-related factors that could have long-term impacts, such as reduced employment levels, inflation, rising interest rates, and reduced consumer spending and consumer confidence, any of which could decrease demand for homes and adversely affect our business. As such, we considered whether impairment indicators arose through the date of filing of this Form 10-K for our goodwill, long-lived assets and other intangible assets and concluded that no factors caused us to impair any asset group during the year ended December 31, 2021. While we ultimately concluded that our goodwill, long-lived assets and other intangibles assets were not impaired as of December 31, 2021, we will continue to assess impairment indicators related to the impact of the COVID-19 pandemic on our business. Goodwill The change in carrying amount of goodwill was as follows (in thousands): Goodwill Accumulated Goodwill January 1, 2020 $ 265,656 $ (70,004) $ 195,652 Business combinations 21,305 — 21,305 Other (87) — (87) December 31, 2020 286,874 (70,004) 216,870 Business combinations 105,617 — 105,617 Other 30 — 30 December 31, 2021 $ 392,521 $ (70,004) $ 322,517 Other changes included in the above table primarily include minor adjustments for the allocation of certain acquisitions still under measurement for the years ended December 31, 2021 and 2020. For additional information regarding changes to goodwill resulting from acquisitions, see Note 17, Business Combinations. At October 1, 2021 , our measurement date, we tested goodwill for impairment by performing a one-step qualitative assessment in conformity with generally accepted accounting principles and determined that no impairment of goodwill was required. As such, no impairment of goodwill was recognized for the year ended December 31, 2021. In addition, no impairment of goodwill was recognized for the years ended December 31, 2020 or 2019. Accumulated impairment losses included within the above table were incurred over multiple periods, with the latest impairment charge being recorded during the year ended December 31, 2010.

The gross carrying amount of intangibles increased approximately $130.1 million and $46.4 million during the years ended December 31, 2021 and 2020, respectively. Intangibles associated with business combinations accounted for approximately $130.0 million and $46.2 million of the increases during the years ended December 31, 2021 and 2020, respectively. For more information, see Note 17, Business Combinations. Amortization expense on intangible assets totaled approximately $37.1 million, $28.5 million, and $24.5 million during the years ended December 31, 2021, 2020 and 2019, respectively.

The Senior Notes will mature on February 1, 2028 and interest is payable semi-annually in cash in arrears on February 1 and August 1, commencing on February 1, 2020. The net proceeds from the Senior Notes offering were $295.0 million after debt issuance costs. The indenture covering the Senior Notes contains restrictive covenants that, among other things, limit the ability of the Company and certain of our subsidiaries (subject to certain exceptions) to: (i) incur additional debt and issue preferred stock; (ii) pay dividends on, redeem or repurchase stock in an aggregate amount exceeding 2.0% of market capitalization per fiscal year, or in an aggregate amount exceeding certain applicable restricted payment baskets; (iii) prepay subordinated debt; (iv) create liens; (v) make specified types of investments; (vi) apply net proceeds from certain asset sales; (vii) engage in transactions with affiliates; (viii) merge, consolidate or sell substantially all of our assets; and (ix) pay dividends and make other distributions from subsidiaries. Credit Facilities In December 2021, we entered into a new $500 million, seven-year term loan facility due December 2028 (the “Term Loan”) under our credit agreement (the “Term Loan Agreement”), dated as of December 14, 2021 with Royal Bank of Canada as the administrative agent and collateral agent thereunder. The Term Loan amortizes in quarterly principal payments of $1.25 million starting on March 31, 2022, with any remaining unpaid balances due on the maturity date of December 14, 2028. The Term Loan bears interest at either the base rate (which approximates the prime rate) or the Eurodollar rate, plus a margin of (A) 1.25% in the case of base rate loans or (B) 2.25% in the case of Eurodollar rate loans. Proceeds from the Term Loan were used to refinance and repay in full all amounts outstanding under our previous term loan agreement. We intend to use the remaining funds to pay for certain fees and expenses associated with the closing of the Term Loan and for general corporate purposes, including acquisitions and other growth initiatives. As of December 31, 2021, we had $493.3 million, net of unamortized debt issuance costs, due on our Term Loan. Subject to certain exceptions, the Term Loan will be subject to mandatory prepayments of (i) 100% of the net cash proceeds from issuances or incurrence of debt by the Company or any of its restricted subsidiaries (other than with respect to certain permitted indebtedness (excluding any refinancing indebtedness); (ii) 100% (with step-downs to 50% and 0% based on achievement of specified net leverage ratios) of the net cash proceeds from certain sales or dispositions of assets by the Company or any of its restricted subsidiaries in excess of a certain amount and subject to reinvestment provision and certain other exception; and (iii) 50% (with step-downs to 25% and 0% based upon achievement of specified net leverage ratios) of excess cash flow of the Company and its restricted subsidiaries in excess of $15 million, subject to certain exceptions and limitations. In September 2019, we entered into an asset-based lending credit agreement (the “ABL Credit Agreement”). The ABL Credit Agreement provides for an asset-based lending credit facility (the “ABL Revolver”) of up to $200.0 million with a five-year maturity. Borrowing availability under the ABL Revolver is based on a percentage of the value of certain assets securing the Company’s obligations and those of the subsidiary guarantors thereunder. In connection with the Term Loan Agreement, we entered into a Third Amendment (the “Third Amendment”) to the Third ABL/Term Loan Intercreditor Agreement with Bank of America, N.A., as ABL Agent for the lenders under the ABL Credit Agreement, and Royal Bank of Canada as collateral agent under the Term Loan Agreement. Including outstanding letters of credit, our remaining availability under the ABL Revolver as of December 31, 2021 was $155.7 million. In February 2022, we amended and extended our ABL Credit Agreement. See Note 19, Subsequent Events, for additional information. All of the obligations under the Term Loan and ABL Revolver are guaranteed by all of the Company’s existing restricted subsidiaries and will be guaranteed by the Company’s future restricted subsidiaries. Additionally, all obligations under the Term Loan and ABL Revolver, and the guarantees of those obligations, are secured by substantially all of the assets of the Company and the guarantors, subject to certain exceptions and permitted liens, including a first-priority security interest in such assets that constitute ABL Priority Collateral, as defined in the ABL Credit Agreement, and a second- priority security interest in such assets that constitute Term Loan Priority Collateral, as defined in the Term Loan Agreement. The ABL Revolver bears interest at either the Eurodollar rate or the base rate (which approximated the prime rate), at the Company’s election, plus a margin of (A) 1.25% or 1.50% in the case of Eurodollar rate loans (based on a measure of availability under the ABL Credit Agreement) and (B) 0.25% or 0.50% in the case of base rate loans (based on a measure of availability under the ABL Credit Agreement). The ABL Revolver also provides incremental revolving credit facility commitments of up to $50.0 million. The terms and conditions of any incremental revolving credit facility commitments must be no more favorable than the terms of the ABL Revolver. The ABL Revolver also allows for the issuance of letters of credit of up to $75.0 million in aggregate and borrowing of swingline loans of up to $20.0 million in aggregate. The ABL Credit Agreement contains a financial covenant requiring the satisfaction of a minimum fixed charge coverage ratio of 1.0x in the event that we do not meet a minimum measure of availability under the ABL Revolver. The ABL Credit Agreement and the Term Loan Agreement contain restrictive covenants that, among other things, limit the ability of the Company and certain of our subsidiaries (subject to certain exceptions) to: (i) incur additional debt and issue preferred stock; (ii) pay dividends on, redeem or repurchase stock in an aggregate amount exceeding 2.0% of market capitalization per fiscal year, or in an aggregate amount exceeding certain applicable restricted payment baskets; (iii) prepay subordinated debt; (iv) create liens; (v) make specified types of investments; (vi) apply net proceeds from certain asset sales; (vii) engage in transactions with affiliates; (viii) merge, consolidate or sell substantially all of our assets; and (ix) pay dividends and make other distributions from subsidiaries. Vehicle and Equipment Notes We are party to a Master Loan and Security Agreement (“Master Loan and Security Agreement”), a Master Equipment Lease Agreement (“Master Equipment Agreement”) and one or more Master Loan Agreements (“Master Loan Agreements” and together with the Master Loan and Security Agreement and Master Equipment Agreement the “Master Loan Equipment Agreements”) with various lenders to provide financing for the purpose of purchasing or leasing vehicles and equipment used in the normal course of business. Each financing arrangement under these agreements constitutes a separate note and obligation. Vehicles and equipment purchased or leased under each financing arrangement serve as collateral for the note applicable to such financing arrangement. Regular payments are due under each note for a period of typically 60 consecutive months after the incurrence of the obligation. The specific terms of each note are based on specific criteria, including the type of vehicle or equipment and the market interest rates at the time. Total gross assets relating to our Master Loan and Equipment Agreements were $134.5 million and $132.2 million as of December 31, 2021 and 2020, respectively. The net book value of assets under these agreements was $65.3 million and $65.7 million as of December 31, 2021 and 2020, respectively. Depreciation of assets held under these agreements is included within cost of sales on the Consolidated Statements of Operations and Comprehensive Income.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Fair Values Fair value is the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820, “Fair Value Measurement,” establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Assets and Liabilities Measured at Fair Value on a Recurring Basis In many cases, a valuation technique used to measure fair value includes inputs from multiple levels of the fair value hierarchy. The lowest level of significant input determines the placement of the entire fair value measurement in the hierarchy. During the periods presented, there were no transfers between fair value hierarchical levels. Assets Measured at Fair Value on a Nonrecurring Basis Certain assets, specifically other intangible and long-lived assets, are measured at fair value on a nonrecurring basis in periods subsequent to initial recognition. Assets measured at fair value on a nonrecurring basis as of December 31, 2021 and 2020 are categorized based on the lowest level of significant input to the valuation. The assets are measured at fair value when our impairment assessment indicates a carrying value for each of the assets in excess of the asset’s estimated fair value. Undiscounted cash flows, a Level 3 input, are utilized in determining estimated fair values. During each of the years ended December 31, 2021, 2020 and 2019, we did not record any impairments on these assets required to be measured at fair value on a nonrecurring basis. Estimated Fair Value of Financial Instruments Accounts receivable, accounts payable and accrued liabilities as of December 31, 2021 and 2020 approximate fair value due to the short-term maturities of these financial instruments. The carrying amounts of certain long-term debt, including the Term Loan and ABL Revolver as of December 31, 2021 and 2020, approximate fair value due to the variable rate nature of the agreements. The carrying amounts of our operating lease right-of-use assets and the obligations associated with our operating and finance leases as well as our vehicle and equipment notes approximate fair value as of December 31, 2021 and 2020. All debt classifications represent Level 2 fair value measurements. Derivative financial instruments are measured at fair value based on observable market information and appropriate valuation methods. Contingent consideration liabilities arise from future earnout payments to the sellers associated with certain acquisitions and are based on predetermined calculations of certain future results. These future payments are estimated by considering various factors, including business risk and projections. The contingent consideration liabilities are measured at fair value by discounting estimated future payments, calculated based on a weighted average of various future forecast scenarios, to their net present value. The fair values of financial assets and liabilities that are recorded at fair value in the Consolidated Balance Sheets and not described above were as follows (in thousands): As of December 31, 2021 As of December 31, 2020 Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Financial assets: Cash equivalents $ 258,055 $ 258,055 $ — $ — $ 170,398 $ 170,398 $ — $ — Derivative financial instruments 14,830 — 14,830 — 5,130 — 5,130 — Total financial assets $ 272,885 $ 258,055 $ 14,830 $ — $ 175,528 $ 170,398 $ 5,130 $ — Financial liabilities: Contingent consideration $ 11,170 $ — $ — $ 11,170 $ 4,004 $ — $ — $ 4,004 Derivative financial instruments 1,937 — 1,937 — 324 — 324 — Total financial liabilities $ 13,107 $ — $ 1,937 $ 11,170 $ 4,328 $ — $ 324 $ 4,004 See Note 5, Cash and Cash Equivalents, for more information on cash equivalents included in the table above. Also see Note 11, Derivatives and Hedging Activities, for more information on derivative financial instruments. The change in fair value of the contingent consideration (a Level 3 input) was as follows (in thousands): Contingent consideration liability—January 1, 2021 $ 4,004 Preliminary purchase price 8,400 Fair value adjustments (413) Accretion in value 1,154 Amounts cancelled (1,035) Amounts paid to sellers (940) Contingent consideration liability—December 31, 2021 $ 11,170 The accretion in value of contingent consideration liabilities is included within administrative expenses on the Consolidated Statements of Operations and Comprehensive Income. The carrying values and associated fair values of financial assets and liabilities that are not recorded at fair value in the Consolidated Balance Sheets and not described above include our Senior Notes. To estimate fair value of our Senior Notes, we utilized third-party quotes which are derived all or in part from model prices, external sources or market prices. The Senior Notes represent a Level 2 fair value measurement and are as follows (in thousands): As of December 31, 2021 As of December 31, 2020 Carrying Value Fair Value Carrying Value Fair Value Senior Notes (1) $ 300,000 $ 311,028 $ 300,000 $ 320,013 (1) Excludes the impact of unamortized debt issuance costs.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	DERIVATIVES AND HEDGING ACTIVITIES Risk Management Objective of Using Derivatives We are exposed to certain risks arising from both our business operations and economic conditions. We manage exposure to a wide variety of business and operational risks through our core business activities. We manage economic risks, including interest rate, liquidity and credit risk primarily by overseeing the amount, sources and duration of debt funding and the use of derivative financial instruments. Specifically, we have entered into derivative financial instruments to manage exposure to interest rate movements that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. Our derivative financial instruments are used to manage differences in the amount, timing and duration of our known or expected cash receipts and known or expected cash payments principally related to our investments and borrowings. Cash Flow Hedges of Interest Rate Risk Our purpose for using interest rate derivatives is to add stability to interest expense and to manage our exposure to interest rate movements. During the year ended December 31, 2021, we used interest rate swaps to hedge the variable cash flows associated with existing variable-rate debt. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. We do not use derivatives for trading or speculative purposes and we currently do not have any derivatives that are not designated as hedges. As of December 31, 2021, we have not posted any collateral related to these agreements. As of December 31, 2021, we had three interest rate swaps. One interest rate swap began July 30, 2021 and has a fixed notional amount of $200.0 million, a fixed rate of 0.51% and a maturity date of April 15, 2030. We also had two interest rate swaps that began December 31, 2021, each with a fixed notional amount of $100.0 million, a fixed rate of 1.37%, and a maturity date of December 15, 2028. Together, these three swaps serve to hedge $400.0 million of the variable cash flows on our variable rate Term Loan through maturity. The assets and liabilities associated with these interest rate swaps are included in other non-current assets and other current liabilities on the Consolidated Balance Sheets at their fair value amounts as described in Note 10, Fair Value Measurements. During the year ended December 31, 2020, we terminated two then-existing interest rate swaps and one then-existing forward interest rate swap. We settled the terminated swaps by making a cash payment of $17.8 million. This payment is classified within cash flows from operating activities within the Consolidated Statements of Cash Flows for the year ended December 31, 2020. The unrealized loss included in accumulated other comprehensive loss associated with the terminated swaps of $17.8 million at the time of termination will be amortized to interest expense over the course of the originally scheduled settlement dates of the terminated swaps. During the years ended December 31, 2021 and 2020, we amortized $3.2 million and $1.3 million, respectively, of the unrealized loss to interest expense, net. The changes in the fair value of derivatives designated and that qualify as cash flow hedges are recorded in other comprehensive income, net of tax on the Consolidated Statements of Operations and Comprehensive Income and in accumulated other comprehensive income on the Consolidated Balance Sheets and subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. We had no such changes during the years ended December 31, 2021 or 2020. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense, net as interest payments are made on our variable-rate debt. Over the next twelve months, we estimate that an additional $5.7 million will be reclassified as an increase to interest expense, net. LIBOR is used as a reference rate for our interest rate swap agreements we use to hedge our interest rate exposure. During the year ended December 31, 2020, we adopted ASU 2020-04, Reference Rate Reform: Facilitation of the Effects of Reference Rate Reform on Financial Reporting (Topic 848). The purpose of this guidance is to provide relief for impacted areas as it relates to impending reference rate reform. We elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation.

Equity [Abstract]
Stockholders' Equity	STOCKHOLDERS’ EQUITY As of December 31, 2021 and 2020, we had losses of $0.2 million and $8.8 million, respectively, in accumulated other comprehensive loss on our Consolidated Balance Sheets. The loss as of December 31, 2021 represented the unrealized loss on our terminated interest rate swaps of $9.9 million , net of taxes, less the effective portion of the unrealized gain on our interest rate swaps o f $9.7 million , net of taxes. The loss as of December 31, 2020 represented the unrealized loss on our terminated interest rate swaps of $12.2 million, net of tax, less the effective portion of the unrealized gain on our forward interest rate swap o f $3.4 million, net of tax . For additional information, see Note 11, Derivatives and Hedging Activities. Our board of directors approved a stock repurchase program whereby we are authorized to purchase shares of our outstanding common stock. As of December 31, 2021, we had $100.0 million remaining under this repurchase program. On February 24, 2022, we announced that our board of directors extended the program end date from March 1, 2022 through March 1, 2023 and authorized an increase in the total amount of our outstanding common stock we can purchase up to $200.0 million. During the year ended December 31, 2020, we repurchased 633 thousand shares of our outstanding common stock with an aggregate price of approximately $33.9 million, or $53.57 average price per share. We did not repurchase any shares during the year ended December 31, 2021. The effect of these treasury shares reducing the number of common shares outstanding is reflected in our earnings per share calculation. In response to COVID-19, we temporarily suspended our share repurchase program from March 2020 until it was reinstated in November 2020. Dividends During the year ended December 31, 2021, we declared and paid the following cash dividends (amount declared and amount paid in thousands): Declaration Date Record Date Payment Date Dividend Per Share Amount Declared Amount Paid 2/23/2021 3/15/2021 3/31/2021 $ 0.30 $ 8,907 $ 8,786 5/5/2021 6/15/2021 6/30/2021 0.30 8,910 8,821 8/5/2021 9/15/2021 9/30/2021 0.30 8,912 8,821 11/4/2021 12/15/2021 12/31/2021 0.30 8,911 8,866 The amount of dividends declared may vary from the amount of dividends paid in a period due to the vesting of restricted stock awards and performance share awards, which accrue dividend equivalent rights that are paid when the award vests. The payment of future dividends will be at the discretion of our board of directors and will depend on our future earnings, capital requirements, financial condition, future prospects, results of operations, contractual restrictions, legal requirements, and other factors deemed relevant by our board of directors. We did not declare or pay any cash dividends on our capital stock during the year ended December 31, 2020. Our credit facilities place restrictions on the amount of dividends and stock repurchases we can make during a fiscal year. See Note 8, Long-Term Debt, for more information.

Retirement Benefits [Abstract]
Employee Benefits	EMPLOYEE BENEFITS Healthcare We participate in multiple healthcare plans, the largest of which is partially self-funded with an insurance company paying benefits in excess of stop loss limits per individual/family. Our healthcare benefit expense (net of employee contributions) was approximately $28.4 million, $24.1 million and $21.9 million for the years ended December 31, 2021, 2020 and 2019, respectively, for all plans. An accrual for estimated healthcare claims incurred but not reported (“IBNR”) is included within accrued compensation on the Consolidated Balance Sheets and was $3.3 million and $3.1 million as of December 31, 2021 and 2020, respectively. Workers’ Compensation We participate in multiple workers’ compensation plans. Under these plans, for a significant portion of our business, we use a high deductible program to cover losses above the deductible amount on a per claim basis. We accrue for the estimated losses occurring from both asserted and unasserted claims. Workers’ compensation liability for premiums is included in other current liabilities on the Consolidated Balance Sheets. Insurance claims and reserves include accruals of estimated settlements for known claims, as well as accruals of actuarial estimates of IBNR claims. In estimating these reserves, historical loss experience and judgments about the expected levels of costs per claim are considered. These claims are accounted for based on actuarial estimates of the undiscounted claims, including IBNR. We believe the use of actuarial methods to account for these liabilities provides a consistent and effective way to measure these highly judgmental accruals. Workers’ compensation expense totaled $17.6 million, $15.7 million and $15.4 million for the years ended December 31, 2021, 2020 and 2019, respectively, and is included in cost of sales on the Consolidated Statements of Operations and Comprehensive Income. Workers’ compensation known claims and IBNR reserves included on the Consolidated Balance Sheets were as follows (in thousands): As of December 31, 2021 2020 Included in other current liabilities $ 8,048 $ 7,703 Included in other long-term liabilities 13,397 11,986 $ 21,445 $ 19,689 We also had an insurance receivable for claims that exceeded the stop loss limit for fully insured policies included on the Consolidated Balance Sheets. This receivable offsets an equal liability included within the reserve amounts noted above and was as follows (in thousands): As of December 31, 2021 2020 Included in other non-current assets $ 2,137 $ 1,854 Retirement Plans We participate in multiple 401(k) plans, whereby we provide a matching contribution of wages deferred by employees and can also make discretionary contributions to each plan. Certain plans allow for discretionary employer contributions only. These plans cover substantially all our eligible employees. During the years ended December 31, 2021, 2020 and 2019, we recognized 401(k) plan expenses of $2.5 million, $2.2 million and $2.0 million, respectively, which is included in administrative expenses on the accompanying Consolidated Statements of Operations and Comprehensive Income. Multiemployer Pension Plans We participate in various multiemployer pension plans under collective bargaining agreements in Washington, Oregon, California and Illinois with other companies in the construction industry. These plans cover our union-represented employees and contributions to these plans are expensed as incurred. These plans generally provide for retirement, death and/or termination benefits for eligible employees within the applicable collective bargaining units, based on specific eligibility/participation requirements, vesting periods and benefit formulas. We do not participate in any multiemployer pension plans that are considered to be individually significant. The risks of participating in these multiemployer pension plans are different from single-employer pension plans. For example: • 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 the multiemployer plan, the unfunded obligations of the plan may be borne by the remaining participating employers. • If a participating employer chooses to stop participating in these multiemployer plans, the employer may be required to pay those plans a withdrawal liability based upon the underfunded status of the plan. We also participate in various multiemployer health and welfare plans that cover both active and retired participants. Health care benefits are provided to participants who meet certain eligibility requirements under the applicable collective bargaining unit. Our contributions to multiemployer pension and health and welfare benefit plans were as follows (in thousands): Years ended December 31, 2021 2020 2019 Pension plans $ 2,783 $ 1,128 $ 809 Health & welfare plans 2,893 952 674 Total contributions $ 5,676 $ 2,080 $ 1,483 The increase in contributions for the year ended December 31, 2021 was driven by the acquisition of Alert Insulation in 2021 and a full year of operations for 2020 acquisitions Insulation Contractors/Magellan Insulation and Norkote, Inc. See Note 17, Business Combinations for more information. Share-Based Compensation Common Stock Awards We periodically grant shares of our common stock under our 2014 Omnibus Incentive Plan to non-employee members of our board of directors and our employees. During the years ended December 31, 2021, 2020 and 2019, we granted approximately four thousand, six thousand and eight thousand shares of restricted stock, respectively, to non-employee members of our board of directors. Substantially all of the stock will vest over a one-year service period. In addition, we granted approximately 0.1 million, 0.2 million and 0.1 million shares of our common stock to employees in each of the years ended December 31, 2021, 2020 and 2019, respectively. Substantially all of the stock will vest in three equal installments (rounded to the nearest whole share) annually over a three-year service period. Performance-Based Stock Awards We periodically grant nonvested stock awards subject to performance-based vesting conditions to certain officers. During the year ended December 31, 2021, we issued approximately 0.1 million shares of our common stock which vest in two equal installments on each of April 20, 2022 and April 20, 2023. In addition, during the year ended December 31, 2021, we established, and our board of directors approved, performance-based targets in connection with common stock awards to be issued to certain officers in 2022 contingent upon achievement of these targets. In addition, there are long-term performance-based restricted stock awards to be issued to certain employees annually through 2022 contingent upon achievement of certain performance targets. These awards are accounted for as liability-based awards since they represent a predominantly-fixed monetary amount that will be settled with a variable number of common shares and as such are included in other current liabilities on the Consolidated Balance Sheets. During the years ended December 31, 2021, 2020 and 2019 we granted approximately five thousand, seven thousand and 11 thousand shares of our common stock, respectively, all of which will vest in 2022. Performance-Based Restricted Stock Units During 2020, we established, and our board of directors approved, performance-based restricted stock units in connection with common stock awards which were issued to certain employees in 2021 based upon achievement of a performance target. In addition, during the year ended December 31, 2021, we established, and our board of directors approved, performance-based restricted stock units in connection with common stock awards to be issued to certain employees in 2022 based upon achievement of a performance target. These units will be accounted for as equity-based awards that will be settled with a fixed number of common shares. During the years ended December 31, 2021, 2020 and 2019 we granted approximately eight thousand, 14 thousand and 14 thousand units, respectively, each of which will vest over a one-year service period. Share-Based Compensation Summary Amounts and changes for each category of equity-based award were as follows: Common Stock Awards Performance-Based Stock Awards Performance-Based Restricted Stock Units Awards Weighted Average Grant Date Fair Value Per Share Awards Weighted Average Grant Date Fair Value Per Share Units Weighted Average Grant Date Fair Value Per Share Nonvested awards/units at December 31, 2020 231,280 $ 48.05 166,961 $ 59.97 13,273 $ 36.51 Granted 55,815 124.88 42,449 123.32 8,470 126.89 Vested (84,641) 48.87 (64,525) 52.79 (12,952) 36.51 Forfeited/Cancelled (3,101) 62.36 (1,484) 123.26 (539) 73.06 Nonvested awards/units at December 31, 2021 199,353 $ 68.99 143,401 $ 81.30 8,252 $ 126.89 The following table summarizes the share-based compensation expense recognized under our 2014 Omnibus Incentive Plan (in thousands): Years ended December 31, 2021 2020 2019 Common Stock Awards $ 5,285 $ 4,116 $ 4,242 Non-Employee Common Stock Awards 465 333 359 Performance-Based Stock Awards 4,528 3,869 3,034 Liability Performance-Based Stock Awards 2,612 1,969 432 Performance-Based Restricted Stock Units 862 539 660 $ 13,752 $ 10,826 $ 8,727 We recorded the following stock compensation expense, by income statement category (in thousands): Years ended December 31, 2021 2020 2019 Cost of sales $ 448 $ 284 $ 374 Selling 204 202 194 Administrative 13,100 10,340 8,159 $ 13,752 $ 10,826 $ 8,727 Administrative stock compensation expense includes all stock compensation earned by our administrative personnel, while cost of sales and selling stock compensation represents all stock compensation earned by our installation and sales employees, respectively. We recognized windfall tax benefits of $1.7 million and $0.3 million for the years ended December 31, 2021 and 2019, and we recognized a tax shortfall of $0.3 million for the year ended December 31, 2020, respectively, within the income tax provision in the Consolidated Statements of Operations and Comprehensive Income.

Valuation Allowance We assess the available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize the existing deferred tax assets on a jurisdiction and by tax filing entity basis. A significant piece of objective negative evidence evaluated is cumulative losses incurred over the most recent three-year period. Such objective evidence limits our ability to consider other subjective positive evidence such as our projections for future growth. Based on this evaluation, a valuation allowance has been recorded as of December 31, 2021 and 2020 for the net deferred tax assets recorded on certain of our wholly owned subsidiaries. Such deferred tax assets relate primarily to net operating losses that are not more likely than not realizable. However, the amount of the deferred tax asset considered realizable could be adjusted if our estimate of future taxable income during the carryforward period changes, or if objective negative evidence in the form of cumulative losses is no longer present. Additional weight may be given to subjective evidence such as our projections for growth in this situation. Uncertain Tax Positions We are subject to taxation in the United States and various state jurisdictions. As of December 31, 2021, our tax years for 2018 through 2020 are subject to examination by the tax authorities. A rollforward of the gross unrecognized tax benefits is as follows (in thousands): Unrecognized tax benefit, January 1, 2019 $ 5,349 Increase as a result of tax positions taken during the period 2,866 Decrease as a result of tax positions taken during the period (2,482) Decrease as a result of expiring statutes (16) Unrecognized tax benefit, December 31, 2019 $ 5,717 Increase as a result of tax positions taken during the period 3,822 Decrease as a result of tax positions taken during the period (2,873) Increase as a result of expiring statutes 10 Unrecognized tax benefit, December 31, 2020 $ 6,676 Increase as a result of tax positions taken during the period 4,482 Decrease as a result of tax positions taken during the period (3,999) Decrease as a result of expiring statutes (2,857) Unrecognized tax benefit, December 31, 2021 $ 4,302 No unrecognized tax positions would affect the effective tax rate at December 31, 2021. Interest expense and penalties accrued related to uncertain tax positions as of December 31, 2021 are $0.5 million. We expect a decrease to the amount of unrecognized tax benefits (exclusive of penalties and interest) within the next twelve months of zero to $2.4 million. Determining uncertain tax positions and the related estimated amounts requires judgment and carry estimation risk. If future tax law changes or interpretations should come to light, or additional information should become known, our conclusions regarding unrecognized tax benefits may change.

Related Party Transactions [Abstract]
Related Party Transactions	RELATED PARTY TRANSACTIONS We sell installation services to other companies related to us through common or affiliated ownership and/or board of directors and/or management relationships. We also purchase services and materials and pay rent to companies with common or related ownership. We lease our headquarters and certain other facilities from related parties. See Note 9, Leases, for future minimum lease payments to be paid to these related parties. The amount of sales to common or related parties as well as the purchases from and rent expense paid to common or related parties were as follows (in thousands): Years ended December 31, 2021 2020 2019 Sales $ 1,452 $ 3,987 $ 13,488 Purchases 1,544 1,841 1,810 Rent 1,322 1,125 1,040 At December 31, 2021 and 2020, we had related party balances of approximately $0.9 million and $0.7 million, respectively, included in accounts receivable on our Consolidated Balance Sheets. These balances primarily represent trade accounts receivable arising during the normal course of business with various related parties. M/I Homes, Inc., a customer whose Chairman, President and Chief Executive Officer was a member of our board of directors until his resignation from our board effective March 18, 2020, accounted for a significant portion of our related party sales during the first quarter of the year ended December 31, 2020 as well as the year ended December 31, 2019 while it was classified as a related party to the Company.

Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Accrued General Liability and Auto Insurances Accrued general liability and auto insurance reserves included on the Consolidated Balance Sheets were as follows (in thousands): As of December 31, 2021 2020 Included in other current liabilities $ 5,889 $ 5,102 Included in other long-term liabilities 16,050 16,440 $ 21,939 $ 21,542 We also had insurance receivables and indemnification assets included on the Consolidated Balance Sheets that, in aggregate, offset equal liabilities included within the reserve amounts noted above. The amounts were as follows (in thousands): As of December 31, 2021 2020 Insurance receivables and indemnification assets for claims under fully insured policies $ 3,578 $ 4,400 Insurance receivables for claims that exceeded the stop loss limit 278 328 Total insurance receivables and indemnification assets included in other non-current assets $ 3,856 $ 4,728 Leases See Note 9, Leases, for further information on our lease commitments. Other Commitments and Contingencies From time to time, various claims and litigation are asserted or commenced against us principally arising from contractual matters and personnel and employment disputes. In determining loss contingencies, management considers the likelihood of loss as well as the ability to reasonably estimate the amount of such loss or liability. An estimated loss is recorded when it is considered probable that such a liability has been incurred and when the amount of loss can be reasonably estimated. As litigation is subject to inherent uncertainties, we cannot be certain that we will prevail in these matters. However, we do not believe that the ultimate outcome of any pending matters will have a material adverse effect on our consolidated financial position, results of operations or cash flows.

Business Combinations [Abstract]
Business Combinations	BUSINESS COMBINATIONS As part of our ongoing strategy to expand geographically and increase market share in certain markets, as well as diversify our products and end markets, we completed eleven, nine and six business combinations during the years ended December 31, 2021, 2020 and 2019, respectively, as well as several insignificant tuck-in acquisitions merged into existing operations in 2019, in which we acquired 100% of the voting equity interests in each acquired entity. Acquisition-related costs amounted to $2.8 million, $2.8 million and $2.1 million for the years ended December 31, 2021, 2020 and 2019, respectively, and are included in Administrative expenses on the Consolidated Statements of Operations and Comprehensive Income. The goodwill recognized in conjunction with these business combinations represents the excess cost of the acquired entity over the net amount assigned to assets acquired and liabilities assumed. We expect to deduct $100.5 million of goodwill for tax purposes as a result of 2021 acquisitions. Below is a summary of each significant acquisition by year, including revenue and net income (loss) since date of acquisition, shown for the year of acquisition. The largest of our 2021 acquisitions were I.W.

These contingent payments consist primarily of earnouts based on performance that are recorded at fair value at the time of acquisition, and/or non-compete agreements and amounts based on working capital calculations. When these payments are expected to be made over one year from the acquisition date, the contingent consideration is discounted to net present value of future payments based on a weighted average of various future forecast scenarios. Further adjustments to the allocation for each acquisition still under its measurement period are expected as third-party or internal valuations are finalized, certain tax aspects of the transaction are completed, contingent consideration is settled, and customary post-closing reviews are concluded during the measurement period attributable to each individual business combination. As a result, insignificant adjustments to the fair value of assets acquired, and in some cases total purchase price, have been made to certain business combinations since the date of acquisition and future adjustments may be made through the end of each measurement period. Goodwill and intangibles per the above table may not agree to the total gross increases of these assets as shown in Note 7, Goodwill and Intangibles, during the years ended December 31, 2021, 2020 and 2019 due to minor adjustments to goodwill for the allocation of certain acquisitions still under measurement as well as other immaterial intangible assets added during the ordinary course of business. In addition, goodwill and intangibles increased during the year ended December 31, 2019 due to various small acquisitions merged into existing operations that do not appear in the above tables.

Earnings Per Share [Abstract]
Income Per Common Share	INCOME PER COMMON SHAREBasic net income per common share is calculated by dividing net income by the weighted average shares outstanding during the period, without consideration for common stock equivalents.Diluted net income per common share is calculated by adjusting weighted average shares outstanding for the dilutive effect of common stock equivalents outstanding for the period, determined using the treasury stock method. Potential common stock is included in the diluted income per common share calculation when dilutive. The dilutive effect of outstanding restricted stock awards after application of the treasury stock method as of December 31, 2021, 2020 and 2019, was 261 thousand, 213 thousand and 120 thousand, respectively.

Subsequent Events [Abstract]
Subsequent Events	SUBSEQUENT EVENTS During the first quarter of 2022, our Chief Executive Officer, who is also our chief operating decision maker, changed the manner in which he reviews financial information for purposes of assessing business performance and allocating resources. In response, we are in the process of modifying our internal reporting and supporting systems to reflect these changes and are evaluating the future impact on our reporting of segments. In February 2022, we amended and extended our ABL Credit Agreement. The ABL Amendment increased the commitment amount under the ABL Revolver to $250.0 million from $200.0 million and extended the maturity to February 17, 2027 from September 26, 2024, and permits us to further increase the commitment amount to up to $300 million. The ABL Amendment provides that the ABL Revolver will bear interest at either the base rate or term Secured Overnight Financing Rate (“Term SOFR”), at our election, plus a margin of 0.25% or 0.50% for base rate advances or 1.25% or 1.50% for Term SOFR advances (in each case based on a measure of availability under the ABL Credit Agreement). The amendment also provides us with the ability to reduce drawn and unused fees based on sustainability-linked key performance indicator targets and makes other modifications to the ABL Credit Agreement. On February 24, 2022, we announced that our board of directors approved a special annual dividend, payable on March 31, 2022 to stockholders of record on March 15, 2022 at a rate of 90 cents per share. In addition, we recently announced that our board of directors declared a quarterly dividend, payable on March 31, 2022 to stockholders of record on March 15, 2022 at a rate of 31.5 cents per share.

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Basis of Presentation	We prepare our consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).
Consolidation	The accompanying consolidated financial statements include all of our wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated.
Use of Estimates	Preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, judgements and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Management believes the accounting estimates are appropriate and reasonably determined; however, due to the inherent uncertainties in making these estimates, actual amounts could differ from such estimates.
Cash and Cash Equivalents	We consider all highly-liquid investments purchased with original term to maturity of three months or less to be cash equivalents.
Revenue and Cost Recognition	Revenue is measured according to Accounting Standards Codification ("ASC") 606, “Revenue from Contracts with Customers.” Our revenues are derived primarily through contracts with customers whereby we install insulation and other complementary building products and are recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. An insignificant portion of our sales, primarily retail and distribution sales, is accounted for on a point-in-time basis when the sale occurs and the risk of loss transfers to the customer, adjusted accordingly for any return provisions and net of any sales taxes. We do offer assurance-type warranties on certain of our installed products and services that do not represent a separate performance obligation and, as such, do not impact the timing or extent of revenue recognition. For contracts that are not complete at the reporting date, we recognize revenue over time utilizing a cost-to-cost input method as we believe this represents the best measure of when goods and services are transferred to the customer. When this method is used, we estimate the costs to complete individual contracts and record as revenue that portion of the total contract price that is considered complete based on the relationship of costs incurred to date to total anticipated costs. Under the cost-to-cost method, the use of estimated costs to complete each contract is a significant variable in the process of determining recognized revenue, requires judgment and can change throughout the duration of a contract due to contract modifications and other factors impacting job completion. The costs of earned revenue include all direct material and labor costs and those indirect costs related to contract performance, such as indirect labor, supplies, tools and repairs. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Our long-term contracts can be subject to modification to account for changes in contract specifications and requirements. We consider contract modifications to exist when the modification either creates new, or changes the existing, enforceable rights and obligations. Most of our contract modifications are for goods or services that are not distinct from the existing contract due to the significant integration service provided in the context of the contract and are accounted for as if they were part of that existing contract. The effect of a contract modification on the transaction price and our measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis. Payment terms typically do not exceed 30 days for short-term contracts and typically do not exceed 60 days for long-term contracts with customers. All contracts are billed either contractually or as work is performed. Billing on our long-term contracts occurs primarily on a monthly basis throughout the contract period whereby we submit invoices for customer payment based on actual or estimated costs incurred during the billing period. On certain of our long-term contracts the customer may withhold payment on an invoice equal to a percentage of the invoice amount, which will be subsequently paid after satisfactory completion of each installation project. This amount is referred to as retainage and is common practice in the construction industry, as it allows for customers to ensure the quality of the service performed prior to full payment. Retainage receivables are classified as current or long-term assets based on the expected time to project completion. See "Accounts Receivable" below for further discussion of our retainage receivables. We generally expense sales commissions and other incremental costs of obtaining a contract when incurred because the amortization period is usually one year or less. Sales commissions are recorded within selling expenses on the Consolidated Statements of Operations and Comprehensive Income. We do not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less.
Derivative Instruments and Hedging Activities	We record all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the earnings effect of the hedged forecasted transactions in a cash flow hedge. We may enter into derivative contracts that are intended to economically hedge certain of our risks, even though hedge accounting does not apply or we elect not to apply hedge accounting.
Business Combinations	The purchase price for business combinations is allocated to the estimated fair values of acquired tangible and intangible assets, including goodwill and assumed liabilities, where applicable. Additionally, we recognize customer relationships, trademarks and trade names, backlog and non-competition agreements as identifiable intangible assets. These assets are recorded at fair value as of the transaction date. The fair value of these intangibles is determined using either the income approach or the market approach using current industry information which involves significant unobservable inputs (Level 3 inputs). These inputs include projected sales, margin and tax rate.At times, the total purchase price for a business combination could be less than the estimated fair values of acquired tangible and intangible assets. In these cases, we record a gain on bargain purchase within other expenses in the Consolidated Statements of Operations and Comprehensive Income rather than goodwill in accordance with U.S. GAAP.
Accounts Receivable	We account for trade receivables based on amounts billed to customers. Past due receivables are determined based on contractual terms. We do not accrue interest on any of our trade receivables.Retainage receivables represent the amount retained by our customers to ensure the quality of the installation and is received after satisfactory completion of each installation project. Management regularly reviews aging of retainage receivables and changes in payment trends and records an allowance when collection of amounts due are considered at risk.
Allowance for Doubtful Accounts	Credit losses are measured according to ASC 326, “Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments.” We consider forward-looking information to estimate expected credit losses for financial instruments, including trade receivables, retainage receivables and contract assets (unbilled receivables). Our expected loss allowance methodology for accounts receivable is developed using historical losses, current economic conditions and future market forecasts. We also perform ongoing evaluations of our existing and potential customer’s creditworthiness. To date, the COVID-19 pandemic has not yet had a material impact on the collectability of our existing trade receivables. See Note 4, Credit Losses, for additional information.
Concentration of Credit Risk	Credit risk is our risk of financial loss from the non-performance of a contractual obligation on the part of our counterparty. Such risk arises principally from our receivables from customers and cash and bank balances. Substantially all of our trade accounts receivable are from entities engaged in residential and commercial construction. We perform periodic credit evaluations of our customers’ financial condition. The general credit risk of our counterparties is not considered to be significant.
Inventories	Inventories consist of insulation, waterproofing materials, fireproofing and fire-stopping materials, garage doors, rain gutters, window blinds, shower doors, mirrors, closet shelving and other products. We value inventory at each balance sheet date to ensure that it is carried at the lower of cost or net realizable value with cost determined using the first-in, first-out (“FIFO”) method. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable cost of completion, disposal and transportation. As of December 31, 2021 and 2020, substantially all inventory was finished goods. Inventory provisions are recorded to reduce inventory to the lower of cost or net realizable value for obsolete or slow moving inventory based on assumptions about future demand and marketability of products, the impact of new product introductions, inventory levels and turns, product spoilage, and specific identification of items such as product discontinuance, engineering/material changes, or regulatory-related changes.
Property and Equipment	Property and equipment are stated at cost, less accumulated depreciation. We provide for depreciation and amortization of property and equipment using the straight-line method over the expected useful lives of the assets. Expected useful lives of property and equipment vary but generally are the shorter of lease life or five years for vehicles and leasehold improvements, three Major renewals and improvements are capitalized. Maintenance, repairs and minor renewals are expensed as incurred. When assets are retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is recorded.
Goodwill	Goodwill results from business combinations and represents the excess of the purchase price over the fair value of acquired tangible assets and liabilities and identifiable intangible assets. Annually, on October 1, or if conditions indicate an earlier review is necessary, we perform a one-step quantitative test to determine if it is more likely than not that the fair value of the reporting unit is less than its carrying amount. The estimate of the reporting unit’s fair value is determined by weighting a discounted cash flow model and a market-related model using current industry information that involve significant unobservable inputs (Level 3 inputs). In determining the estimated future cash flow, we consider and apply certain estimates and judgments, including current and projected future levels of income based on management’s plans, business trends, prospects, market and economic conditions and market-participant considerations. An impairment charge is recognized for the amount by which the carrying value exceeds the reporting unit's fair value, not to exceed the total amount of goodwill allocated to the reporting unit.
Impairment of Other Intangible and Long-Lived Assets	Other intangible assets consist of customer relationships, backlog, non-competition agreements and business trademarks and trade names. Amortization of finite lived intangible assets is recorded to reflect the pattern of economic benefits based on projected revenues over their respective estimated useful lives (customer relationships – eight one two
Other Liabilities	Our workers’ compensation insurance program, for a significant portion of our business, is considered a high deductible program whereby we are responsible for the cost of claims under approximately $0.8 million. Our general liability insurance program is considered a high retention program whereby we are responsible for the cost of claims up to approximately $5.0 million, subject to an aggregate cap of $10.0 million. Our vehicle liability insurance program is considered a high deductible program whereby we are responsible for the cost of claims under approximately $1.0 million. In each case, if we do not pay these claims, our insurance carriers are required to make these payments to the claimants on our behalf. The liabilities represent our best estimate of our costs, using generally accepted actuarial reserving methods, of the ultimate obligations for reported claims plus those incurred but not reported for all claims incurred through December 31, 2021 and 2020. We establish case reserves for reported claims using case-basis evaluation of the underlying claims data and we update as information becomes known. We regularly monitor the potential for changes in estimates, evaluate our insurance accruals and adjust our recorded provisions. The assumptions underlying the ultimate costs of existing claim losses are subject to a high degree of unpredictability, which can affect the liability recorded for such claims. For example, variability in inflation rates of health care costs inherent in workers’ compensation claims can affect the ultimate costs. Similarly, changes in legal trends and interpretations, as well as a change in the nature and method of how claims are settled, can affect ultimate costs. Our estimates of liabilities incurred do not anticipate significant changes in historical trends for these variables and any changes could have a considerable effect on future claim costs and currently recorded liabilities. We carry insurance for a number of risks, including, but not limited to, workers’ compensation, general liability, vehicle liability, property and our obligation for employee-related health care benefits. Liabilities relating to claims associated with these risks are estimated by considering historical claims experience, including frequency, severity, demographic factors and other actuarial assumptions. In estimating our liability for such claims, we periodically analyze our historical trends, including loss development, and apply appropriate loss development factors to the incurred costs associated with the claims with the assistance of external actuarial consultants. While we do not expect the amounts ultimately paid to differ significantly from our estimates, our reserves and corresponding expenses could be affected if future claim experience differs significantly from historical trends and actuarial assumptions.
Advertising Costs	Advertising costs are generally expensed as incurred.
Deferred Financing Costs	Deferred financing costs and debt issuance costs combined, totaling $11.4 million and $7.0 million, net of accumulated amortization as of December 31, 2021 and 2020, respectively, are amortized over the term of the related debt on a straight-line basis which approximates the effective interest method. The deferred financing costs are included in other non-current assets while the debt issuance costs are included in long-term debt on the Consolidated Balance Sheets as of December 31, 2021 and 2020, respectively. The related amortization expense of these costs combined was $1.4 million, $1.3 million and $1.2 million and is included in interest expense, net on the Consolidated Statements of Operations and Comprehensive Income for the years ended December 31, 2021, 2020 and 2019, respectively. We wrote off $0.2 million and $3.3 million in previously capitalized loan costs during the years ended December 31, 2021 and 2019, respectively. In addition, we expensed loan costs of approximately $1.6 million and $0.4 million for the years ended December 31, 2021 and 2019, respectively, associated with our credit facilities because they did not meet the requirements for capitalization. We had no such write offs or expenses during the year ended December 31, 2020. These amounts are included in interest expense, net on the Consolidated Statements of Operations and Comprehensive Income. We also had $7.5 million in new costs associated with the debt-related financing transactions incurred during the year ended December 31, 2021. The deferred financing costs are included in other non-current assets while the debt issuance costs are included in long-term debt on the Consolidated Balance Sheets. These costs are amortized over the term of the related debt on a straight-line basis which approximates the effective interest method.
Leases	Leases are measure according to ASC 842, “Leases,” which requires substantially all leases, with the exception of leases with a term of one year or less, to be recorded as a lease liability measured as the present value of the future lease payments with a corresponding right-of-use asset. ASC 842 also requires disclosures designed to give financial statement users information on the amount, timing and uncertainty of cash flows. We determine if an arrangement is a lease at inception. Most of our operating leases do not provide an implicit rate so we use our incremental borrowing rate based on the information available at the commencement date to determine the present value of future payments. Leases with an initial term of 12 months or less are not recorded on the balance sheet as we recognize lease expense for these leases on a straight-line basis over the lease term. We elect to not separate lease components from non-lease components for all fixed payments, and we exclude variable lease payments in the measurement of right-of-use assets and lease obligations.
Share-Based Compensation	Our share-based compensation program is designed to attract and retain employees while also aligning employees’ interests with the interests of our stockholders. Restricted stock awards are periodically granted to certain employees, officers and non-employee members of our board of directors under the stockholder-approved 2014 Omnibus Incentive Plan. Certain of our stock awards are deemed to be equity-based with a service condition and do not contain a market or performance condition with the exception of performance-based awards granted to certain officers and performance-based stock units. Fair value of the non-performance-based awards to employees and officers is measured at the grant date and amortized to expense over the vesting period of the awards using the straight-line attribution method for all service-based awards with a graded vesting feature. This fair value is reduced by assumed forfeitures and adjusted for actual forfeitures until vesting. We also issue performance-based stock awards to certain officers under our 2014 Omnibus Incentive Plan. The performance-based compensation expense is recorded over the requisite service period using the graded-vesting method for the entire award. Performance-based stock awards are accounted for at fair value at date of grant. We also periodically grant performance-based stock units to certain employees under the stockholder-approved 2014 Omnibus Incentive Plan. These units convert to shares upon meeting time- and performance-based requirements. Compensation expense for performance-based stock units is recorded based on an assessment each reporting period of the probability that certain performance goals will be met during the contingent vesting period. If performance goals are not probable to occur, no compensation expense will be recognized. If performance goals that were previously deemed probable are not or are not expected to be met, the previously recognized compensation cost related to such performance goals will be reversed. Employees and officers are subject to tax at the vesting date based on the market price of the shares on that date, or on the grant date if an election is made.
Income Taxes	We account for income taxes using the asset and liability method. Under this method, the amount of taxes currently payable or refundable are accrued and deferred tax assets and liabilities are recognized for the estimated future tax consequences of temporary differences that currently exist between the tax basis and financial reporting basis of our assets and liabilities. Valuation allowances are established against deferred tax assets when it is more likely than not that the realization of those deferred tax assets will not occur. In evaluating our ability to recover our deferred tax assets within the jurisdiction from which they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, the ability to produce future taxable income, prudent and feasible tax planning strategies and recent financial operations. In projecting future taxable income, we factor in historical results and changes in accounting policies and incorporate assumptions, including the amount of future federal and state pretax operating income, the reversal of temporary differences and the implementation of feasible and prudent tax planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates we use to manage the underlying businesses. Deferred tax assets and liabilities are measured using the enacted tax rates in effect in the years when those temporary differences are expected to reverse. The effect on deferred taxes from a change in tax rate is recognized through operations in the period that includes the enactment date of the change. Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the future. A tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. Income tax positions must meet a more likely than not recognition threshold to be recognized. We recognize tax liabilities for uncertain tax positions and adjust these liabilities when our judgment changes as a result of the evaluation of new information not previously available. Liabilities related to uncertain tax positions are recorded in other long-term liabilities on the Consolidated Balance Sheets. Due to the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from the current estimate of the tax liabilities. These differences will be reflected as increases or decreases to income tax expense and the effective tax rate in the period in which the new information becomes available. Interest and penalties related to unrecognized tax benefits are recognized within income tax expense in the Consolidated Statements of Operations and Comprehensive Income. Accrued interest and penalties are recognized in other current liabilities on the Consolidated Balance Sheets. Our income tax expense, deferred tax assets and liabilities and reserves for unrecognized tax benefits reflect management’s best assessment of estimated future taxes to be paid. We are subject to income taxes in the United States, which includes numerous state and local jurisdictions. Significant judgments and estimates are required in determining the income tax expense, deferred tax assets and liabilities and the reserve for unrecognized tax benefits.

Fair Values	Fair value is the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820, “Fair Value Measurement,” establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Assets and Liabilities Measured at Fair Value on a Recurring Basis In many cases, a valuation technique used to measure fair value includes inputs from multiple levels of the fair value hierarchy. The lowest level of significant input determines the placement of the entire fair value measurement in the hierarchy. During the periods presented, there were no transfers between fair value hierarchical levels. Assets Measured at Fair Value on a Nonrecurring Basis Certain assets, specifically other intangible and long-lived assets, are measured at fair value on a nonrecurring basis in periods subsequent to initial recognition. Assets measured at fair value on a nonrecurring basis as of December 31, 2021 and 2020 are categorized based on the lowest level of significant input to the valuation. The assets are measured at fair value when our impairment assessment indicates a carrying value for each of the assets in excess of the asset’s estimated fair value. Undiscounted cash flows, a Level 3 input, are utilized in determining estimated fair values. During each of the years ended December 31, 2021, 2020 and 2019, we did not record any impairments on these assets required to be measured at fair value on a nonrecurring basis. Estimated Fair Value of Financial Instruments Accounts receivable, accounts payable and accrued liabilities as of December 31, 2021 and 2020 approximate fair value due to the short-term maturities of these financial instruments. The carrying amounts of certain long-term debt, including the Term Loan and ABL Revolver as of December 31, 2021 and 2020, approximate fair value due to the variable rate nature of the agreements. The carrying amounts of our operating lease right-of-use assets and the obligations associated with our operating and finance leases as well as our vehicle and equipment notes approximate fair value as of December 31, 2021 and 2020. All debt classifications represent Level 2 fair value measurements.
