Accounting Policies [Abstract]
Significant Accounting Policies	NOTE 2 – 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. 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. We had $99.2 million and $69.8 million of cash equivalents as of December 31, 2019 and 2018, respectively. Substantially all cash is held in banks providing FDIC coverage of $0.25 million per depositor. Revenue and Cost Recognition On January 1, 2018, we adopted the new accounting standard ASC 606, “Revenue from Contracts with Customers,” using the modified retrospective method applied to those contracts that were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under Topic 605. See Note 3, Revenue Recognition, for the detailed revenue recognition policy. 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 10, Derivatives and Hedging, for additional information on our accounting policy for derivative instruments and hedging activities. Investment Policy Marketable securities with held-to-maturity held-to-maturity. 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 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 $33.4 million and $28.0 million as of December 31, 2019 and 2018, respectively. In addition, as of December 31, 2019, $0.5 million of retainage receivables are recorded in other long-term assets. Allowance for Doubtful Accounts We maintain an allowance for doubtful accounts for estimated losses resulting from the failure of customers to make required payments. The allowance is determined by management based on our historical losses, specific customer circumstances and general economic conditions. We analyze aged accounts receivable and generally increase the allowance as receivables age. Management reviews accounts receivable and records an allowance for specific customers based on current circumstances and charges off the receivable against the allowance when all attempts to collect the receivable have failed. This analysis is performed regularly and the allowance is adjusted accordingly. The following table sets forth our allowance for doubtful accounts (in thousands): January 1, 2017 $ 3,397 Charged to costs and expenses 2,834 Charged to other accounts (1) 699 Deductions (2) (2,125 ) December 31, 2017 $ 4,805 Charged to costs and expenses 2,630 Charged to other accounts (1) 675 Deductions (2) (3,025 ) December 31, 2018 $ 5,085 Charged to costs and expenses 4,312 Charged to other accounts (1) 1,269 Deductions (2) (3,788 ) December 31, 2019 $ 6,878 (1) Recovery of receivables previously written off as bad debt and other. (2) Write-off Concentration of Credit Risk Credit risk is our risk of financial loss from the non-performance risk of our is not considered to be significant. In addition, no individual customer made up more than % of accounts receivable or % of net revenue for the years ended December 31, 2019, 2018 and 2017. Inventories Inventories consist of insulation, waterproofing 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 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 five years 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 either perform a quantitative test or assess qualitative factors to determine if it is more likely than not that the fair value of the reporting unit is less than its carrying amount and if it is necessary to perform the quantitative two-step Impairment of Other Intangible and Long-Lived Assets Other intangible assets consist of customer relationships, backlog, non-competition eight non-competition one five years 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, 2019, 2018 and 2017. 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 $2.0 million, subject to an aggregate cap of $8.0 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, 2019 and 2018. 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 $3.9 million, $3.8 million and $3.2 million for the years ended December 31, 2019, 2018 and 2017, 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 $8.2 million and $6.4 million, net of accumulated amortization as of December 31, 2019 and 2018, 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 We wrote off $3.3 million in previously capitalized loan costs during the year ended December 31, 2019. In addition, we expensed loan costs of approximately $0.4 million, $1.1 million and $1.0 million for the years ended December 31, 2019, 2018 and 2017, respectively, associated with our credit facilities because they did not meet the requirements for capitalization. These amounts are included in interest expense, net on the Condensed Consolidated Statements of Operations and Comprehensive Income. We also had $6.7 million in new costs associated with the debt-related financing transactions incurred during the year ended December 31, 2019. The deferred financing costs are included in other non-current For additional information on our debt instruments, see Note 7, Long-Term Debt. Leases On January 1, 2019, we adopted the new accounting standard ASU 2016-02, right-of-use 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 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 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. The Tax Cuts and Jobs Act (the “Tax Act”) was enacted on December 22, 2017 reduced the U.S. federal corporate tax rate from 35% to 21% effective January 1, 2018. During the year end December 31, 2017, the Company recognized a $3.8 million tax benefit as a result of revaluing the ending net deferred tax liabilities from 35% to the newly enacted U.S. corporate income tax rate of 21%, and also recognized a $0.8 million benefit in 2018 due to timing provision to return adjustments which impacted deferred balances at the 35% rate that were then revalued at the lower corporate rate. See Note 13, Income Taxes, for additional information. 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.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	NOTE 3 – REVENUE RECOGNITION 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 sales, is accounted for on a point-in-time 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 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 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. We disaggregate our revenue from contracts with customers by end market and product, as we believe it best depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. The following tables present our revenues disaggregated by end market and product (in thousands): Year ended December 31, 2019 2018 Residential new construction $ 1,138,475 75 % $ 1,026,473 77 % Repair and remodel 98,771 7 % 89,977 7 % Commercial 274,383 18 % 219,982 16 % Net revenues $ 1,511,629 100 % $ 1,336,432 100 % Year ended December 31, 2019 2018 Insulation $ 970,070 64 % $ 876,118 66 % Waterproofing 112,075 7 % 97,683 7 % Shower doors, shelving and mirrors 105,745 7 % 90,352 7 % Garage doors 89,959 6 % 79,539 6 % Rain gutters 49,788 3 % 44,203 3 % Window blinds 41,641 3 % 28,981 2 % Other building products 142,351 10 % 119,556 9 % Net revenues $ 1,511,629 100 % $ 1,336,432 100 % Contract assets and liabilities related to our uncompleted contracts and customer deposits were as follows (in thousands): As of December 31, 2019 2018 Contract assets $ 22,138 $ 15,092 Contract liabilities (8,888 ) (7,468 ) Uncompleted contracts were as follows (in thousands): As of December 31, 2019 2018 Costs incurred on uncompleted contracts $ 110,818 $ 114,826 Estimated earnings 61,185 58,952 Total 172,003 173,778 Less: Billings to date 155,599 163,112 Net under billings $ 16,404 $ 10,666 Net under billings were as follows (in thousands): As of December 31, 2019 2018 Costs and estimated earnings in excess of billings on uncompleted contracts (contract assets) $ 22,138 $ 15,092 Billings in excess of costs and estimated earnings on uncompleted contracts (contract liabilities) (5,734 ) (4,426 ) Net under billings $ 16,404 $ 10,666 The difference between contract assets and contract liabilities as of December 31, 2019 compared to December 31, 2018 is primarily the result of timing differences between our performance of obligations under contracts and customer payments. During the year ended December 31, 2019, we recognized $7.2 million of revenue that was included in the contract liability balance at December 31, 2018. We did no 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, 2019, the aggregate amount of the transaction price allocated to remaining uncompleted contracts was $90.7 million. We expect to satisfy remaining performance obligations and recognize revenue on substantially all of these uncompleted contracts over the next 18 months. Practical Expedients and Exemptions 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.

The ABL Credit Agreement provides for an asset-based lending credit facility (the “ABL Revolver”) of up to $200.0 million with a five aturity, which replaced the Company’s previous revolving credit facility. 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 Amended and Restated Term Loan, we entered into a Second Amendment (the “Second Amendment”) to the ABL/Term Loan Intercreditor Agreement with Bank of America, N.A., as ABL Agent for the lenders under the ABL Credit Agreement, and Bank of America, N.A., as Term Loan Agent for the lenders under the Amended and Restated Term Loan. Including outstanding letters of credit, our remaining availability under the ABL Revolver as of December 31, 2019 was $161.3 million. 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 1.0 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.

Leases [Abstract]
Leases	NOTE 8 – LEASES On January 1, 2019, we adopted ASC 842, “Leases” which, among other changes, requires us to record liabilities classified as operating leases on our Condensed Consolidated Balance Sheets along with a corresponding right-of-use non-lease right-of-use Upon adoption of ASC 842, we recorded a $44.9 million increase in other assets, a $1.4 million decrease to other current assets, a $1.0 million decrease to other current liabilities and a $44.5 million increase to operating lease obligations. These adjustments are the result of assigning a right-of-use 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. We lease various assets in the ordinary course of business as follows: warehouses to store our materials and perform staging activities for certain products we install; various office spaces for selling and administrative activities to support our business; and certain vehicles and equipment to facilitate our operations, including, but not limited to, trucks, forklifts and office equipment. 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. 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.

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, 2019 and 2018 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, 2019, 2018 and 2017, 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, 2019 and 2018 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, 2019 and 2018, approximate fair value due to the variable rate nature of the agreements. The carrying amounts of our operating lease right-of-use 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 to their net present value using the appropriate weighted average cost of capital (WACC). 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, 2019 As of December 31, 2018 Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Financial assets: Cash equivalents $ 99,242 $ 99,242 $ — $ — $ 69,807 $ 69,807 $ — $ — Derivative financial instruments — — — — 1,765 — 1,765 — Total financial assets $ 99,242 $ 99,242 $ — $ — $ 71,572 $ 69,807 $ 1,765 $ — Financial liabilities: Derivative financial instruments $ 9,446 $ — $ 9,446 $ — $ 2,275 $ — $ 2,275 $ — Contingent consideration 3,854 — — 3,854 5,098 — — 5,098 Total financial liabilities $ 13,300 $ — $ 9,446 $ 3,854 $ 7,373 $ — $ 2,275 $ 5,098 See Note 4, Investments, for more information on cash equivalents included in the table above.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	NOTE 10 – 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, 2019, such derivatives were used to hedge the variable cash flows associated with existing variable-rate debt. To accomplish these objectives, we primarily use interest rate swaps as part of our interest rate risk management strategy. 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. As of December 31, 2019, we had two one May 31, 2022 one April 15, 2025 May 31, 2022 April 15, 2025 three non-current 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 Condensed Consolidated Statements of Operations and Comprehensive Income and in accumulated other comprehensive income on the Condensed Consolidated Balance Sheets and subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. We had no 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 $1.6 million will be reclassified as an increase to interest expense, net. Additionally, 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, 2019, we have not posted any collateral related to these agreements.

Employee Benefits	NOTE 12 – EMPLOYEE BENEFITS Healthcare We participate in multiple healthcare plans, of which our primary plan is partially self-funded with an insurance company paying benefits in excess of stop loss limits per individual. Our healthcare benefit expense (net of employee contributions) was approximately $21.9 million, $17.8 million and $17.4 million for the years ended December 31, 2019, 2018 and 2017, 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 $2.6 million and $2.3 million as of December 31, 2019 and 2018, 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 $15.4 million, $12.8 million and $13.5 million for the years ended December 31, 2019, 2018 and 2017, 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, 2019 2018 Included in other current liabilities $ 6,777 $ 5,795 Included in other long-term liabilities 10,874 9,447 $ 17,651 $ 15,242 We also had an insurance receivable for claims that exceeded the stop loss limit for fully insured policies As of December 31, 2019 2018 Included in other non-current $ 2,098 $ 1,888 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, 2019, 2018 and 2017, we recognized 401(k) plan expenses of $2.0 million, $1.7 million and $1.6 million, respectively, which is included in administrative expenses on the accompanying Consolidated Statements of Operations and Comprehensive Income. Share-Based Compensation Common Stock Awards During the years ended December 31, 2019, 2018 and 2017, we granted approximately eight five six share, respectively, which represents market price on the grant dates to non-employee In addition, in each of the years ended December 31, 2019, 2018 and 2017, we granted approximately 0.1 million shares of our common stock under our 2014 Omnibus Incentive Plan to our employees.

This expense is subject to future adjustments for forfeitures and is expected to be recognized over the remaining weighted-average period of 1.6 years using the graded-vesting method. See the table below for changes in shares and related weighted average fair market value per share. Employees – Performance-Based Restricted Stock Units During the year ended December 31, 2018, we established, and our board of directors approved, performance-based stock units in connection with common stock awards which we issued to certain employees during the year ended December 31, 2019. In addition, during the year ended December 31, 2019, we established, and our board of directors approved, performance-based stock units in connection with common stock awards to be issued to certain employees in 2020 contingent upon achievement of a performance target, which was met in 2019, as well as a one-year , and $2.6 million , As of December 31, 2019, there was $0.2 million of unrecognized compensation expense related to nonvested performance-based stock units. This expense is subject to future adjustments for forfeitures and is expected to be recognized on a straight-line basis over the remaining weighted-average period of 0.3 years. See the table below for changes in shares and related weighted average fair market value per share. Share-Based Compensation Summary During the years ended December 31, 2019, 2018 and 2017, our employees surrendered approximately 45 thousand, 41 thousand and 11 thousand, respectively, of our common stock to satisfy tax withholding obligations arising in connection with the vesting of common stock awards issued under our 2014 Omnibus Incentive Plan. We recognized excess tax benefits of approximately $0.3 million, $0.5 million and $0.6 million for the years ended December 31, 2019, 2018 and 2017, respectively, within the income tax provision on 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 Based on this evaluation, a valuation allowance has been recorded as of December 31, 2019 and 2018 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, 2019, our tax years for 2016 2018 Unrecognized tax benefit, January 1, 2017 $ 4,097 Increase as a result of tax positions taken during the period 4,353 Decrease as a result of tax positions taken during the period (2,311 ) Decrease as a result of expiring statutes (1,689 ) Unrecognized tax benefit, December 31, 2017 $ 4,450 Increase as a result of tax positions taken during the period 3,846 Decrease as a result of tax positions taken during the period (2,850 ) Decrease as a result of expiring statutes (97 ) Unrecognized tax benefit, December 31, 2018 $ 5,349 Increase as a result of tax positions taken during the perio d 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 Unrecognized tax benefits of $2.8 million at December 31, 2019 would affect the effective tax rate.

We expect a decrease to the amount of unrecognized tax benefits (exclusive of penalties and interest) within the next twelve months of zero 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.

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. During the year ended December 31, 2018, we entered into an agreement with one of our suppliers to purchase a portion of the insulation materials we utilize across our business. This agreement is effective January 1, 2019 through December 31, 2021 with a purchase obligation of $21.1 million for 2020 and $14.0 million for 2021. During the fourth quarter of 2019, our commitment for the year ended December 31, 2019 was reduced to $11.8 million , which is equal to the total amount we purchased during the year .

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 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 do not agree to the total gross increases of these assets as shown in Note 6, Goodwill and Intangibles, during the years ended December 31, 2019, 2018 and 2017 due to minor adjustments to goodwill for the allocation of certain acquisitions still under measurement, an immaterial goodwill reclassification in the year ended December 31, 2017 related to the prior period, as well as other immaterial intangible assets added during the ordinary course of business. In addition, goodwill and intangibles increased during the years ended December 31, 2019, 2018 and 2017 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	NOTE 17 – INCOME PER COMMON SHARE Basic 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, 2019, 2018 and 2017, was 120 thousand, 122 thousand and 117 thousand, respectively.

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	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	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.
Cash and Cash Equivalents	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. We had $99.2 million and $69.8 million of cash equivalents as of December 31, 2019 and 2018, respectively. Substantially all cash is held in banks providing FDIC coverage of $0.25 million per depositor.
Revenue Recognition	Revenue and Cost Recognition On January 1, 2018, we adopted the new accounting standard ASC 606, “Revenue from Contracts with Customers,” using the modified retrospective method applied to those contracts that were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under Topic 605. See Note 3, Revenue Recognition, for the detailed revenue recognition policy.
Derivative Instruments and Hedging Activities	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 10, Derivatives and Hedging, for additional information on our accounting policy for derivative instruments and hedging activities.
Investment Policy	Investment Policy Marketable securities with held-to-maturity held-to-maturity.
Business Combinations	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 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	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 $33.4 million and $28.0 million as of December 31, 2019 and 2018, respectively. In addition, as of December 31, 2019, $0.5 million of retainage receivables are recorded in other long-term assets.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts We maintain an allowance for doubtful accounts for estimated losses resulting from the failure of customers to make required payments. The allowance is determined by management based on our historical losses, specific customer circumstances and general economic conditions. We analyze aged accounts receivable and generally increase the allowance as receivables age. Management reviews accounts receivable and records an allowance for specific customers based on current circumstances and charges off the receivable against the allowance when all attempts to collect the receivable have failed. This analysis is performed regularly and the allowance is adjusted accordingly. The following table sets forth our allowance for doubtful accounts (in thousands): January 1, 2017 $ 3,397 Charged to costs and expenses 2,834 Charged to other accounts (1) 699 Deductions (2) (2,125 ) December 31, 2017 $ 4,805 Charged to costs and expenses 2,630 Charged to other accounts (1) 675 Deductions (2) (3,025 ) December 31, 2018 $ 5,085 Charged to costs and expenses 4,312 Charged to other accounts (1) 1,269 Deductions (2) (3,788 ) December 31, 2019 $ 6,878 (1) Recovery of receivables previously written off as bad debt and other. (2) Write-off
Concentration of Credit Risk	Concentration of Credit Risk Credit risk is our risk of financial loss from the non-performance risk of our is not considered to be significant. In addition, no individual customer made up more than % of accounts receivable or % of net revenue for the years ended December 31, 2019, 2018 and 2017.
Inventories	Inventories Inventories consist of insulation, waterproofing 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
Property and Equipment	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 five years 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 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 either perform a quantitative test or assess qualitative factors to determine if it is more likely than not that the fair value of the reporting unit is less than its carrying amount and if it is necessary to perform the quantitative two-step
Impairment of Other Intangible and Long-Lived Assets	Impairment of Other Intangible and Long-Lived Assets Other intangible assets consist of customer relationships, backlog, non-competition eight non-competition one five years 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, 2019, 2018 and 2017.
Other Liabilities	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 $2.0 million, subject to an aggregate cap of $8.0 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, 2019 and 2018. 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 Advertising costs are generally expensed as incurred. Advertising expense was approximately $3.9 million, $3.8 million and $3.2 million for the years ended December 31, 2019, 2018 and 2017, respectively, and is included in selling expense on the Consolidated Statements of Operations and Comprehensive Income.
Deferred Financing Costs	Deferred Financing Costs Deferred financing costs and debt issuance costs combined, totaling $8.2 million and $6.4 million, net of accumulated amortization as of December 31, 2019 and 2018, 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 We wrote off $3.3 million in previously capitalized loan costs during the year ended December 31, 2019. In addition, we expensed loan costs of approximately $0.4 million, $1.1 million and $1.0 million for the years ended December 31, 2019, 2018 and 2017, respectively, associated with our credit facilities because they did not meet the requirements for capitalization. These amounts are included in interest expense, net on the Condensed Consolidated Statements of Operations and Comprehensive Income. We also had $6.7 million in new costs associated with the debt-related financing transactions incurred during the year ended December 31, 2019. The deferred financing costs are included in other non-current For additional information on our debt instruments, see Note 7, Long-Term Debt.
Leases	Leases On January 1, 2019, we adopted the new accounting standard ASU 2016-02, right-of-use
Share-Based Compensation	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 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 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	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. The Tax Cuts and Jobs Act (the “Tax Act”) was enacted on December 22, 2017 reduced the U.S. federal corporate tax rate from 35% to 21% effective January 1, 2018. During the year end December 31, 2017, the Company recognized a $3.8 million tax benefit as a result of revaluing the ending net deferred tax liabilities from 35% to the newly enacted U.S. corporate income tax rate of 21%, and also recognized a $0.8 million benefit in 2018 due to timing provision to return adjustments which impacted deferred balances at the 35% rate that were then revalued at the lower corporate rate. See Note 13, Income Taxes, for additional information. 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.
