Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2018

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 and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates include the revenue, costs and reserves established under the percentage-of-completion method, allowance for doubtful accounts, valuation allowance on deferred tax assets, valuation of acquired intangible assets, periodic impairment evaluation of intangible assets and other long-lived assets, share-based compensation and the accounting for self-insurance reserves. 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. We had $69.8 million and $55.6 million of cash equivalents as of December 31, 2018 and 2017, 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

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 9, Derivatives and Hedging, for additional information on our accounting policy for derivative instruments and hedging activities.

Investment Policy

Marketable securities with original maturities longer than three months but less than one year from the settlement date are classified as investments within current assets. These investments consist of highly liquid investment grade instruments primarily including corporate bonds and commercial paper. Investments for which we have the ability and positive intent to hold to maturity are carried at amortized cost. The difference between the acquisition costs and face values of held-to-maturity investments is amortized over the remaining term of the investments and added to or subtracted from the acquisition cost and interest income. As of December 31, 2018, all of our investments were classified as 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 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 primarily using the income approach and 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 $28.0 million and $23.1 million as of December 31, 2018 and 2017, respectively. As of December 31, 2018, all but $0.6 million of retainage receivables, which are recorded in other long-term assets, were estimated to be contractually due within one year.

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):


Allowance for doubtful accounts receivable
January 1, 2016	$	2,486
Charged to costs and expenses		2,928
Charged to other accounts (1)		435
Deductions (2)		(2,452	)

December 31, 2016	$	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

(1)	Recovery of receivables previously written off as bad debt and other

(2)	Write-off of uncollectible accounts receivable

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 4% of net revenue for the years ended December 31, 2018, 2017 and 2016.

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 (“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, 2018 and 2017, 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 to five years for furniture, fixtures and equipment and 30 years for buildings.

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 goodwill impairment test. If we perform the quantitative test, we compare the carrying value of the reporting unit to an estimate of the reporting unit’s fair value to identify potential impairment. 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. If the estimated fair value of the reporting unit is less than the carrying value, a second step is performed to determine the amount of the potential goodwill impairment. If impaired, goodwill is written down to its estimated implied fair value.

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 to 15 years, non-competition agreements – one to five years and business trademarks and trade names – two to 15 years). We do not have any indefinite-lived intangible assets other than goodwill.

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, 2018, 2017 and 2016.

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 $0.5 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, 2018 and 2017. 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 $3.8 million, $3.2 million and $3.0 million for the years ended December 31, 2018, 2017 and 2016, 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 $6.4 million and $6.8 million, net of accumulated amortization as of December 31, 2018 and 2017, 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, 2018 and 2017, respectively. The related amortization expense of these costs combined was $1.2 million, $1.1 million and $0.4 million and is included in interest expense, net on the Consolidated Statements of Operations and Comprehensive Income for the years ended December 31, 2018, 2017 and 2016, respectively. In addition, we expensed loan costs of approximately $1.1 million and $1.0 million for the years ended December 31, 2018 and 2017, respectively, associated with our Senior Secured Credit Agreements because they did not meet the requirements for capitalization. For the years ended December 31, 2018 and 2017, we wrote off $0.1 million and $2.1 million, respectively, in previously capitalized loan costs as a result of refinancing our credit facilities. For additional information, see Note 7, Long-Term Debt.

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. 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 12, 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.

Recently Adopted Accounting Pronouncements


Standard		Adoption
ASU 2014-09, Revenue from Contracts with Customers (Topic 606)		ASC 606 sets forth a new revenue recognition model that requires identifying the contract(s) with a customer, identifying the performance obligations in the contract, determining the transaction price, allocating the transaction price to the performance obligations and recognizing the revenue upon satisfaction of performance obligations. We adopted the provisions of ASU 2014-09 and related subsequently-issued amendments beginning on January 1, 2018 using the modified retrospective approach and, as such, recognized a $2.1 million cumulative effect, net of tax, of initially applying the standard as an increase to the opening balance of retained earnings on January 1, 2018. See Note 3, Revenue Recognition, for further information regarding our revenue recognition policies and the revisions to correct certain immaterial misstatements.
ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities		ASU 2017-12 better aligns a company’s risk management activities and financial reporting for hedging relationships and makes certain improvements to simplify the application of hedge accounting guidance. For public business entities, this update is effective for financial statements issued for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years, with early adoption permitted. We elected to early adopt this ASU effective January 1, 2018 and, as such, recognized a $0.1 million adjustment to our opening retained earnings and accumulated other comprehensive income as of January 1, 2018 to reclassify the cash flow hedge ineffectiveness previously recorded in net income in the fourth quarter of 2017 to accumulated other comprehensive income.
ASU 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118		In March 2018, the Financial Accounting Standards Board issued ASU 2018-05, which became effective immediately. ASU 2018-05 adds various SEC paragraphs pursuant to the issuance of the December 2017 SEC Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Act (“SAB 118”). See Note 12, Income Taxes, for additional information regarding the adoption of ASU 2018-05.
ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a Consensus of the FASB Emerging Issues Task Force)		ASU 2018-15 amends the existing accounting standards for capitalizing implementation costs of internal-use software by including service contracts in a cloud computing arrangement. For public business entities, this update is effective for financial statements issued for fiscal years beginning after December 15, 2019 and interim periods therein, with early adoption permitted. We elected to early adopt this ASU using the prospective approach effective July 1, 2018 and, as such, have capitalized certain implementation costs associated with service contracts in a cloud computing arrangement. The effects of adoption were not significant.

Recently Issued Accounting Pronouncements Not Yet Adopted

We are currently evaluating the impact of certain ASUs on our Consolidated Financial Statements or Notes to Consolidated Financial Statements, which are described below:


Standard	Description	Effective date	Effect on the financial statements or other significant matters
ASU 2016-02, Leases (Topic 842)	This pronouncement and related subsequently-issued amendments change the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. ASC 842 requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief.	Annual periods beginning after December 15, 2018, including interim periods therein. Early adoption is permitted.	This ASU requires substantially all leases, with the exception of leases with a term of one year or less, to be recorded on the balance sheet as a lease liability measured as the present value of the future lease payments with a corresponding right-of-useasset. This ASU also requires disclosures designed to give financial statement users information on the amount, timing and uncertainty of cash flows. We are currently finalizing the evaluation of our leases including the impact on our consolidated financial statements. As part of our evaluation, we elected a number of practical expedients, including the “practical expedients package” determined in ASC 842-10-65-1. We estimate we will record an increase of lease-related assets and liabilities as of January 1, 2019 of approximately $43.0 million in the consolidated balance sheets. The impact to our consolidated statements of operations and comprehensive income and consolidated statements of cash flows
			is not expected to be material.
ASU 2016-13, Financial Instruments-Credit Losses (Topic 326)	This pronouncement amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. In addition, these amendments require the measurement of all expected credit losses for financial assets, including trade accounts receivable, held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts.	Annual periods beginning after December 15, 2019, including interim periods therein. Early adoption is permitted.	We are currently evaluating whether this ASU will have a material impact on our consolidated financial statements.
ASU 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment	To address concerns over the cost and complexity of the two-step goodwill impairment test, this pronouncement removes the second step of the goodwill impairment test. Going forward, an entity will apply a one-step quantitative test and record the amount of goodwill impairment as the excess of a reporting unit’s carrying amount over its fair value, not to exceed the total amount of goodwill allocated to the reporting unit.	Annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019, including interim periods therein. Early adoption is permitted.	We are currently evaluating the provisions of this ASU and the impact it will have on our disclosures.
ASU 2018-13, Fair Value Measurement (Topic 820):Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement	This pronouncement amends Topic 820 to eliminate, add and modify certain disclosure requirements for fair value measurements.	Annual periods beginning after December 15, 2019, including interim periods therein. Early adoption is permitted.	We are currently evaluating the provisions of this ASU and the impact it will have on our disclosures.
ASU 2018-16, Derivatives and Hedging (Topic 815)—Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes	This pronouncement permits the use of the Overnight Index Swap (“OIS”) Rate based on the Secured Overnight Financing Rate (“SOFR”) as a U.S. benchmark interest rate for hedge accounting purposes.	For public business entities that already have adopted the amendments in ASU 2017-12, the amendments are effective for annual periods beginning after December 15, 2018, including interim periods therein. As we have already adopted ASU 2017-12effective January 1, 2018, we will adopt this ASU as of January 1, 2019.	We do not expect this ASU to have a material impact on our financial statements until we transition from LIBOR to SOFR rates, which will likely not occur in 2019. We will reevaluate whether these changes will have a material impact at the time of transition.
