Organization

NOTE 1 – ORGANIZATION

Installed Building Products, Inc. (“IBP”), a Delaware corporation formed on October 28, 2011, and its wholly owned subsidiaries (collectively referred to as the “Company” and “we”, “us” and “our”), primarily install insulation, garage doors, rain gutters, shower doors, closet shelving and mirrors, and other products for residential and commercial builders located in the continental United States. The Company operates in over 100 locations within the continental United States and its corporate office is located in Columbus, Ohio.

We have one operating segment and a single reportable segment. Substantially all of our sales come from service-based installation of various products in the residential new construction, repair and remodel and commercial construction end markets. Each of our branches has the capacity to serve all of our end markets. The following table sets forth the annual percentage of our net revenue by end market:

2014 Initial Public Offering (“IPO”)

On February 10, 2014, in anticipation of our IPO, we executed a 19.5-for-one stock split of our common stock, which consisted of 1,129,944 shares of common stock issued and outstanding immediately prior to the stock split. The effect of the stock split on outstanding shares and earnings per share has been retroactively applied to all periods presented. Following the split, we had 22,033,901 stock-split adjusted shares of common stock issued and outstanding.

On February 19, 2014, we completed an IPO of our common stock, which resulted in the sale of 8,567,500 shares. We received total proceeds from the IPO of $94,242 based upon the price of $11.00 per share. We used $6,597 of the proceeds from our IPO to pay underwriting fees, $75,735 to redeem our Series A Preferred Stock, $0.01 par value per share (the “Redeemable Preferred Stock”), and $11,910 to pay down our revolving credit facility. Our common stock is listed on The New York Stock Exchange under the symbol “IBP.”

2014 Secondary Public Offering

On June 17, 2014, we completed a secondary offering of 9,314,196 shares of our common stock at a public offering price of $12.50 per share. The total offering size reflects 8,100,000 shares of common stock offered and sold on behalf of certain selling stockholders (the “Selling Stockholders”) and 1,214,196 shares that were offered and sold by us pursuant to the exercise of the underwriters’ option to purchase additional shares. We did not receive any proceeds from the sale of shares by the Selling Stockholders. However, we received $14,418, after deducting underwriting discounts but before estimated offering expenses payable by us, from the exercise of the underwriters’ option to purchase additional shares.

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 and majority owned subsidiaries. The non-controlling interest relating to a majority owned subsidiary is not significant for presentation. 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 allowance for doubtful accounts, valuation allowance on deferred tax assets, valuation of the reporting unit, intangible assets and other long-lived assets, share based compensation, reserves for general liability, and workers’ compensation and medical insurance. 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. All such items referenced herein are classified as cash and we have no items classified as cash equivalents as of the years ended December 31, 2015 or 2014. Substantially all cash is held in two banks at December 31, 2015. The banks provide FDIC coverage of $0.25 million per depositor.

Revenue Recognition

Revenue from the sale and installation of products is recognized when all of the following have occurred: (i) persuasive evidence of an arrangement exists; (ii) delivery has occurred or services have been rendered; (iii) the price is fixed or determinable; and (iv) the ability to collect is reasonably assured. Revenue from the sale and installation of products is recognized net of adjustments and discounts and at the time the installation is complete.

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, 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 rather than goodwill in accordance with generally accepted accounting principles.

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.

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 sets forth our allowance for doubtful accounts (in thousands):


Allowance for doubtful accounts receivable
January 1, 2013	$	1,412
Charged to costs and expenses		1,038
Charged to other accounts (1)		479
Deductions (2)		(1,191	)

December 31, 2013	$	1,738

Charged to costs and expenses		1,900
Charged to other accounts (1)		292
Deductions (2)		(1,269	)

December 31, 2014	$	2,661

Charged to costs and expenses		919
Charged to other accounts (1)		533
Deductions (2)		(1,627	)

December 31, 2015	$	2,486

(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, 2015, 2014 and 2013.

Inventories

Inventories consist of insulation, garage doors, rain gutters, shower doors, mirrors, closet shelving and other products. We install these products but do not manufacture them. We value inventory at the lower of cost or market with cost determined using the first-in, first-out (“FIFO”) method. As of December 31, 2015 and 2014, all inventory was finished goods.

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 assess qualitative factors to determine if it is more likely than not that the fair value of a 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 and 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, 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—two to five years and business trademarks and trade names—eight to 15 years). We do not have any indefinite-lived intangible assets other than goodwill.

We review long-lived 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 market 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, 2015, 2014 and 2013.

Other Liabilities

Our workers’ compensation insurance is primarily under a high-deductible insurance policy and our general liability insurance is under a self-insured retention program (“SIR”). We are insured for covered claims above the deductible and SIR. 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, 2015 and 2014. 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.

Advertising Costs

Advertising costs are expensed as incurred. Advertising expense was approximately $2.3 million, $1.6 million and $1.6 million for the years ended December 31, 2015, 2014 and 2013, respectively, and is included in selling expense on the Consolidated Statements of Operations.

Other Operating Expenses

We recorded $1.4 million of settlement expenses in 2013 related to two lawsuits against us, of which approximately $0.9 million was included in Other operating expenses and $0.5 million was included in Administrative operating expenses during the year ended December 31, 2013. All expenses were paid by December 31, 2014.

Deferred Financing Costs

Deferred financing costs totaling $1.1 million and $0.6 million, net are amortized over the term of the related debt on a straight-line basis which approximates the effective interest method and are included in other non-current assets on the Consolidated Balance Sheets as of December 31, 2015 and 2014, respectively. The related amortization expense of these costs was $0.3 million, $0.2 million and $0.2 million and is included in interest expense on the Consolidated Statements of Operations for the years ended December 31, 2015, 2014 and 2013, respectively. We also wrote off the remaining loan costs associated with our old credit agreement upon entering into our previous credit agreement. These costs of $0.2 million are included in interest expense on the Consolidated Statements of Operations for the year ended December 31, 2014. See Note 5, Long-Term Debt, for more information on our credit agreement.

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. The awards are deemed to be equity-based with a service condition and do not contain a market condition. Fair value of the 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. 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. The future income tax benefit associated with these awards is recorded over the vesting period. In the event dividends are ultimately declared and paid, a forfeiture rate for the unvested restricted shares would be applied.

Insurance 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.

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 begin with historical results adjusted for the results of discontinued operations 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 continuing 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. Management is not aware of any such changes that would have a material effect on our results of operations, cash flows, or financial position.

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 current liabilities and 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. Accrued interest and penalties are recognized in accrued expenses 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.

Discontinued Operations

We continually review each of our markets in order to refine our overall investment strategy and optimize capital and resource allocations in an effort to enhance our financial position and increase our value. If a component of the Company or a group of components of the Company are disposed, we will report the activities of the component or group of components in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on our operations and financial results. Customers of discontinued locations will not be served by other locations. There were no material assets or liabilities related to our discontinued operations as of December 31, 2015 or 2014. Discontinued operations were not segregated in the Consolidated Statements of Cash Flows.

This policy was implemented upon the adoption of ASU 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity” on January 1, 2015. Prior to the adoption of the new standard, we performed a review of both external market factors and our position in each market. We did not discontinue any operations during the year ended December 31, 2014 and all expenses incurred during that period relate to operations discontinued in prior periods. During the year ended December 31, 2013, we elected to discontinue operations in certain underperforming markets.

Estimated Fair Value of Financial Instruments

Accounts receivable, accounts payable, and accrued liabilities as of December 31, 2015 and 2014 approximate their fair value due to the short-term maturities of these financial instruments. The carrying amounts of the long-term debt, including the term loan, delayed draw term loan and revolving credit facility, under the Prior Credit Agreement and the Term Loan, Delayed Draw Term Loan Facility and Revolving LOC under the new Credit and Security Agreement, approximate their fair values as of December 31, 2015 and 2014 due to the short term maturities of the underlying variable rate LIBOR agreements. The carrying amount of the obligations associated with our capital leases approximate fair value as of December 31, 2015 and 2014 because the associated assets generate sufficient cash to settle the obligations. All debt classifications represent value measurements.

Recently Adopted Accounting Pronouncements

In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” The amendments in this update change the requirements for reporting discontinued operations in Subtopic 205-20. A discontinued operation may include a component of an entity or a group of components of an entity, or a business or nonprofit activity. A disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. We adopted this ASU effective January 1, 2015 and have concluded that it has not had a material impact on our consolidated financial statements.

In November 2015, the FASB issued ASU 2015-17, “Income Taxes (Topic 740), Balance Sheet Classification of Deferred Assets.” This ASU is intended to simplify the presentation of deferred taxes on the balance sheet and will require an entity to present all deferred tax assets and deferred tax liabilities as non-current on the balance sheet. Under the current guidance, entities are required to separately present deferred taxes as current or non-current. Netting deferred tax assets and deferred tax liabilities by tax jurisdiction will still be required under the new guidance. The new accounting guidance is effective for annual periods beginning after December 15, 2016 with early adoption permitted. We adopted ASU 2015-17 as of December 31, 2015 and applied the new guidance prospectively. Our deferred tax balances as of December 31, 2014 have not been revised. We have concluded this new ASU has not had and will not have a material impact on our consolidated financial statements.

Recently Issued Accounting Pronouncements Not Yet Adopted

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” ASU 2014-09 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. In July 2015, the FASB voted to defer the application of the provisions of this standard for public companies until annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. We are still evaluating whether this ASU will have a material impact on our consolidated financial statements.

In April 2015, the FASB issued ASU 2015-03, “Interest—Imputation of Interest.” The amendments in this update require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. For public business entities, the amendments in this update are effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. We are still evaluating whether this ASU will have a material impact on our consolidated financial statements.

In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330).” The amendments in this update require an entity to measure inventory within the scope of this update at the lower of cost and net realizable value. For public business entities, the amendments in this update are effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. We are still evaluating whether this ASU will have a material impact on our consolidated financial statements.

In August 2015, the FASB issued ASU 2015-15, “Imputation of Interest (Subtopic 835-30).” This ASU amends ASU 2015-03 regarding the presentation and subsequent measurement of debt issuance costs related to line of credit arrangements. Specifically, it provides guidance for deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line of credit arrangement, regardless of whether there are any outstanding borrowings on the line of credit arrangement. For public business entities, the amendments in this update are effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. We are still evaluating whether this ASU will have a material impact on our consolidated financial statements.

In September 2015, the FASB issued ASU 2015-16, “Business Combinations (Topic 805).” This ASU requires an acquirer to retrospectively adjust provisional amounts recognized in a business combination during the measurement period. To simplify the accounting for adjustments made to provisional amounts, the amendments in this update require that the acquirer recognize adjustments to provisional amounts that are identified during the measurement-period in the reporting period in which the adjustment amount is determined. The acquirer is required to also record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. In addition, an entity is required to present separately on the face of the income statement or disclose in the notes to the financial statements the portion of the amount recorded in current period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. We are still evaluating whether this ASU will have a material impact on our consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” The amendments in this update amend 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. For public business entities, the amendments in this update are effective for annual reporting periods beginning after December 15, 2018, including interim periods within those fiscal years, and early adoption is permitted as of the standard’s issuance date. ASU 2016-02 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. We are still evaluating whether this ASU will have a material impact on our consolidated financial statements.

As of December 31, 2015, we had $87.7 million of unused borrowing capacity under our $200.0 million credit agreement (the “Prior Credit Agreement”), and we had $12.3 million of letters of credit outstanding under the Prior Credit Agreement. We had no outstanding balance under the revolving line of credit under the Prior Credit Agreement at December 31, 2015 or 2014.

On February 29, 2016 we entered into an amended and restated Credit and Security Agreement with a bank group with an aggregate commitment of $325.0 million and a maturity date of February 21, 2021 (the “Credit and Security Agreement”). We used a portion of the funds from the Credit and Security Agreement to pay off the outstanding balances under our previous credit agreement. See Note 15, Subsequent Events for further information.

Vehicle and Equipment Notes

In 2014 and 2015, we entered into a Master Loan and Security Agreement (“Master Loan Agreement” and a Master Equipment Lease Agreement (“Master Equipment Agreement”) with various lenders to provide financing for the purpose of purchasing or leasing vehicles and equipment used in the normal course of business. Each financing arrangement under these agreements constitutes a separate note and obligation. Vehicles and equipment purchased or leased under each financing arrangement serve as collateral for the note applicable to such financing arrangement. Regular payments are due under each note for a period of typically 60 consecutive months after the incurrence of the obligation. The specific terms of each note are based on specific criteria, including the type of vehicle or equipment and the market interest rates at the time. No termination date applies to these agreements.

Total gross assets relating to our master loan agreements were $25.4 million and $1.4 million as of December 31, 2015 and 2014, respectively, none of which were fully depreciated as of December 31, 2015 and 2014, respectively. The net book value of assets under these agreements was $22.4 million and $1.3 million as of December 31, 2015 and 2014, respectively, net of accumulated depreciation of $3.0 million and $0.1 million as of December 31, 2015 and 2014, respectively. Depreciation of assets held under these agreements is included within cost of sales on the Consolidated Statements of Operations.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

NOTE 6 – FAIR VALUE MEASUREMENTS

Fair Values

Fair value is the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

Accounting Standards Codification (“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.

Estimated Fair Value of Financial Instruments

Accounts receivable, accounts payable, and accrued liabilities as of December 31, 2015 and 2014 approximate their fair value due to the short-term maturities of these financial instruments. The carrying amounts of the long-term debt, including the Term Loan, DDTL and LOC, under the Prior Credit Agreement and the Term Loan, Delayed Draw Term Loan Facility and Revolving LOC under the new Credit and Security Agreement approximate their fair values as of December 31, 2015 and 2014 due to the short term maturities of the underlying variable rate LIBOR agreements. The carrying amounts of the obligations associated with our capital leases approximate fair value as of December 31, 2015 and 2014 because the associated costs generate sufficient cash to settle the obligations.

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.

Our Redeemable Preferred Stock was redeemed in February 2014 with proceeds from our initial public offering (“IPO”), eliminating the associated put option. In addition, the redeemable feature of our Redeemable Common Stock was terminated upon the IPO. As such, these balances were zero as of December 31, 2015 and 2014.

The following is a general description of the valuation methodologies used for liabilities and mezzanine equity (which includes preferred redeemable and common stock) items measured at fair value:

Put option—Redeemable Preferred Stock—We identified a certain embedded feature in the Redeemable Preferred Stock that was required to be bifurcated and accounted for as a derivative. The identified put option allowed Redeemable Preferred stockholders to put their shares upon a change in control. The estimated fair value of the put option on Redeemable Preferred Stock was determined using our estimates of the probability of a change in control during each period the option is outstanding in combination with the accreted fair value of the Redeemable Preferred Stock during the option period. Those resulting probabilities were then calculated at net present value. An increase in the probability of the change in control would have increased the fair value of the embedded derivative. We have not entered into and currently do not hold derivatives for trading or speculative purposes.

Redeemable Common Stock—The estimated fair value of the redeemable feature of certain shares of our outstanding common stock was determined using a combination of discounted cash flows and market multiple approach modeling. The fair value was estimated using this method to mark the Redeemable Common Stock to market at each period end. The weighted average cost of capital (“WACC”) used to estimate fair value was approximately 18% as of December 31, 2013.

Changes in the fair value of recurring fair value measurements using significant unobservable inputs (Level 3) for the year ended December 31, 2014 were as follows (in thousands):


Balance as of January 1, 2013	$	18,028
Adjustments to fair value measurement impacting the Statement of Stockholders’ Deficit and Redeemable Instruments		63,764
Adjustments to fair value measurement impacting the Statement of Operations		(292	)

Balance as of January 1, 2014		81,500
Adjustments to fair value measurement impacting the Statement of Stockholders’ Deficit and Redeemable Instruments		8,357
Adjustments to fair value measurement impacting the Statement of Operations		(490	)
Termination of Redemption Feature on common stock and put option		(89,367	)

Balance as of December 31, 2014	$	—

The unrealized gain related to the put option liabilities is recorded within other expense (income) on the Consolidated Statements of Operations.

Assets Measured at Fair Value on a Nonrecurring Basis

Certain 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, 2015 and 2014 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, 2015, 2014 and 2013, we did not record any impairments on these assets required to be measured at fair value on a nonrecurring basis. See the “Impairment of Other Intangible and Long-Lived Assets” caption of Note 2, Significant Accounting Policies, for more information.

Stockholders' Equity and Redeemable Instruments	Dec. 31, 2015
Equity [Abstract]
Stockholders' Equity and Redeemable Instruments	NOTE 7 – STOCKHOLDERS’ EQUITY AND REDEEMABLE INSTRUMENTS As of December 31, 2015 and 2014, we had 5.0 million shares of preferred stock authorized with no shares issued or outstanding, 100.0 million shares of common stock authorized, approximately 32.0 million and 31.8 million shares of common stock issued and approximately 31.4 million and 31.5 million shares of common stock outstanding, all with par value of $0.01, and approximately 0.6 million and 0.3 million shares of treasury stock at cost, respectively. In December 2014, we entered into a share repurchase agreement with Cetus Capital II, LLC, a related party, for the purchase of 300,000 shares of our common stock for an aggregate purchase price of $5.3 million, or $17.61 per share, which was the last reported sales price of the company’s common stock on December 11, 2014. The effect of these treasury shares reducing the number of common shares outstanding is reflected in our earnings per share calculation. For additional information on the related party relationship, see Note 10, Related Party Transactions. In March 2015, we entered into a share repurchase agreement with Installed Building Systems, Inc. (“IBS”), a related party, for the purchase of approximately 0.3 million shares of our common stock for a purchase price of approximately $6.1 million (or $19.23 per share, which represented a 7.5% discount to the last reported price of our common stock on March 13, 2015). The effect of these treasury shares reducing the number of common shares outstanding is reflected in our earnings per share calculation. For additional information on the related party relationship, see Note 10, Related Party Transactions.

Employee Benefits

Postemployment Benefits [Abstract]

Employee Benefits

NOTE 8 – 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 $11.8 million, $8.1 million and $8.0 million for the years ended December 31, 2015, 2014 and 2013, 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 $1.5 million and $1.1 million as of December 31, 2015 and 2014, respectively.

Workers’ Compensation

We participate in multiple workers’ compensation plans. Under these plans, 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. 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 $12.0 million, $9.8 million and $5.9 million for the years ended December 31, 2015, 2014 and 2013, respectively. Workers’ compensation known claims and IBNR reserves included on the Consolidated Balance Sheets were as follows (in thousands):


	December 31, 2015		December 31, 2014
Included in other current liabilities	$	3,263	$	2,504
Included in other long-term liabilities		7,132		5,752

	$	10,395	$	8,256

We also had an insurance receivable for claims that exceeded the stop loss limit included on the Consolidated Balance Sheets. That receivable offsets an equal liability included within the reserve amounts noted above and was as follows (in thousands):


	December 31, 2015		December 31, 2014
Included in other non-current assets	$	1,542	$	2,286

Profit-Sharing Plans

We also participate in various profit-sharing and 401(k) plans. Certain plans provide that eligible employees can defer a portion of their wages into the trust, subject to current Internal Revenue Code rules and limitations. 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, 2015, 2014 and 2013, we recognized 401(k) plan expenses of $0.8 million, $0.7 million and $0.7 million, respectively, which is included in administrative expenses on the accompanying Consolidated Statements of Operations.

Share-Based Compensation

Directors

We periodically grant shares of restricted stock to members of our Board of Directors. Accordingly, we record compensation expense within administrative expenses on the Consolidated Statements of Operations at the time of the grant.

In 2015 and 2014, we granted approximately 13 thousand and 23 thousand shares of restricted stock, respectively, at a price of $22.74 and $12.77 per share, respectively (which represents market price on the grant dates), to non-employee members of our Board of Directors. Accordingly, for each of the years ended December 31, 2015 and 2014, we recorded $0.3 million in compensation expense related to these grants within administrative expenses on the Consolidated Statements of Operations. These shares effectively vested on the grant date since there is deemed to be no service period associated with these awards. The lack of a vesting or service period may not apply to any future share grants under our 2014 Omnibus Incentive Plan.

The weighted-average grant date fair value is the same as the issue price for all shares.

Employees

During the twelve months ended December 31, 2015, we granted approximately 0.1 million shares of restricted stock which vest between January 7, 2016 and March 31, 2016 for non-executive employees and in three equal installments (rounded to the nearest whole share) on each of March 31, 2016, March 31, 2017 and March 31, 2018 for certain officers. We recorded $1.8 million in compensation expense related to these grants within administrative expenses on the Consolidated Statements of Operations for the year ended December 31, 2015. No shares of restricted stock were awarded during the year ended December 31, 2014, and, accordingly, no expense was incurred.

Nonvested restricted stock for employees as of December 31, 2015 was as follows:


	Restricted Stock Awards			Weighted Average Grant Date Fair Market Value Per Share
Nonvested restricted stock at December 31, 2014		—		$	—
Granted		130,613			21.53
Vested		—			—
Forfeited		(1,560	)		21.79

Nonvested restricted stock at December 31, 2015		129,053		$	21.52

As of December 31, 2015, there was $0.9 million of unrecognized compensation expense related to nonvested restricted stock. 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 1.2 years. Shares forfeited are returned as treasury shares and available for future issuances.

As of December 31, 2015, approximately 2.8 million of the 3.0 million shares of common stock authorized for issuance were available for issuance under the 2014 Omnibus Incentive Plan.

Net deferred tax liabilities	$	(14,110	)	$	(9,698	)

We adopted ASU 2015-17 as of December 31, 2015 and applied the new guidance prospectively. Our deferred tax balances as of December 31, 2014 have not been revised. ASU 2015-17 allows for the classification of all deferred tax assets and liabilities as long-term.

As of December 31, 2015, we have federal and state income tax net operating loss (NOL) carryforwards of $8.0 million, the earliest of which expires in 2030.

Valuation Allowance

We assess the available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize the existing deferred tax assets on a jurisdiction and by tax filing entity basis. A significant piece of objective negative evidence evaluated is cumulative losses incurred over the most recent three-year period. Such objective evidence limits our ability to consider other subjective positive evidence such as our projections for future growth.

Based on this evaluation, a valuation allowance has been recorded as of December 31, 2015 and 2014 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, 2015, our tax years for 2012 through 2014 are subject to examination by the tax authorities. A rollforward of the gross unrecognized tax benefits is as follows (in thousands):


Unrecognized tax benefit, January 1, 2014	$	1,311
Increase as a result of tax positions taken during the period		2,545
Decrease as a result of tax positions taken during the period		(1,039	)

Unrecognized tax benefit, December 31, 2014		2,817
Increase as a result of tax positions taken during the period		2,647
Decrease as a result of tax positions taken during the period		(1,415	)
Decrease as a result of expiring statutes		(463	)

Unrecognized tax benefit, December 31, 2015	$	3,586

The amount of unrecognized tax benefits at December 31, 2015 that would affect the effective tax rate is $1.9 million. Interest expense and penalties accrued related to uncertain tax positions as of December 31, 2015 are $84 thousand.

We expect a decrease to the amount of unrecognized tax benefits (exclusive of penalties and interest) within the next twelve months of zero to $1.7 million.

Determining uncertain tax positions and the related estimated amounts requires judgment and carry estimation risk. If future tax law changes or interpretations should come to light, or additional information should become known, our conclusions regarding unrecognized tax benefits may change.

Related Party Transactions

NOTE 10 – RELATED PARTY TRANSACTIONS

We sell installation services to other companies related to us through common or affiliated ownership and/or Board of Directors and/or management relationships. We also purchase services and materials and pay rent to companies with common or related ownership. See Note 11, Commitments and Contingencies, for future minimum lease payments to be paid to these related parties.

For the years ended December 31, 2015, 2014 and 2013, the amount of sales to common or related parties as well as the purchases from and rent expense paid to common or related parties were as follows (in thousands):


	Years ended December 31,
	2015		2014		2013
Sales	$	6,720	$	6,026	$	1,188
Purchases		480		3,100		10,292
Rent		598		600		671

During the second quarter of 2014, we appointed a new member to our Board of Directors who is the CEO of M/I Homes, Inc. (NYSE: MHO), one of our customers. As a result, we have included all sales to this customer in the above table beginning in the year ended December 31, 2014, which coincides with the year the member joined our Board of Directors.

At December 31, 2015 and 2014, we had related party balances of approximately $1.8 million and $1.3 million, respectively, included in accounts receivable on our Consolidated Balance Sheets. These balances primarily represent trade accounts receivable arising during the normal course of business with various related parties. M/I Homes, Inc. accounted for $1.0 million and $0.6 million of the total accounts receivable, related party balances as of December 31, 2015 and 2014, respectively.

On March 13, 2015, we entered into a share repurchase agreement with IBS for the purchase of 0.3 million shares of our common stock. Jeff Edwards, our Chief Executive Officer, is the President of IBS and, in such role, has sole voting and dispositive power over the shares held by IBS and is deemed beneficial ownership in the shares of our common stock held by IBS. See Note 7, Stockholders’ Equity, for additional information.

In December 2014, we entered into a share repurchase agreement with Cetus Capital II, LLC (“Cetus”) for the purchase of 0.3 million shares of our common stock for an aggregate purchase price of $5.3 million. A member of our Board of Directors is affiliated with Cetus, thus classifying this as a transaction with a related party. See Note 7, Stockholders’ Equity, for additional information.

As a result of our acquisition of TCI Contracting, LLC (“TCI”) in 2012, one of our existing suppliers became classified as a related party until a change in ownership of the supplier resulted in an end to such classification during 2014. While still classified as a related party to us, purchases made from this supplier during the years ended December 31, 2014 and 2013 were approximately $2.6 million and $10.1 million, respectively, and are included in total related party purchases in the preceding table.

As of December 31, 2014, the Company maintained a receivable from IBP Holding Company, related to us through direct control by Jeff Edwards, in the amount of approximately $0.6 million. The receivable represented amounts owed to us for wages and related expenses paid by the Company during 2011 to former employees of IBP Holding Company and was included in other current assets on the Consolidated Balance Sheet as of December 31, 2014. During the year ended December 31, 2015, we received the full remaining balance and accordingly, no such receivable existed as of December 31, 2015.

Leases

We are obligated under capital leases covering vehicles and certain equipment. Total assets relating to capital leases were approximately $64.9 million and $65.2 million as of December 31, 2015 and 2014, respectively, and a total of approximately $19.1 million and $20.5 million were fully depreciated as of December 31, 2015 and 2014, respectively. The vehicle and equipment leases generally have terms ranging from four to six years. The net book value of assets under capital leases was approximately $22.1 and $28.8 million as of December 31, 2015 and 2014, respectively, net of accumulated depreciation of approximately $42.8 million and $36.4 million, respectively. Amortization of assets held under capital leases is included within cost of sales on the Consolidated Statements of Operations.

We also have several noncancellable operating leases, primarily for buildings, improvements, equipment, and certain vehicles. These leases generally contain renewal options for periods ranging from one to five years and require us to pay all executory costs such as property taxes, maintenance and insurance.

Future minimum lease payments under noncancellable operating leases (with initial or remaining lease terms in excess of one year) and future minimum capital lease payments as of December 31, 2015 are as follows (in thousands):

Supply Contract Commitments

As of December 31, 2015, we had two product supply contracts, one extending through December 31, 2016 and one extending through August 31, 2017. The contract extending through August 31, 2017 has been suspended through December 31, 2016. Our obligations for both contracts are based on quantity without a specific rate applied and therefore are not quantifiable. We expect our quantity purchases to exceed the minimum quantity commitments for all years covered by the contracts. Actual purchases made under the contract extending through December 31, 2016 for the years ended December 31, 2015, 2014 and 2013 were approximately $61.0 million, $46.4 million and $16.6 million, respectively.

Other Commitments and Contingencies

From time to time, various claims and litigation are asserted or commenced against us principally arising from contractual matters and personnel and employment disputes. In determining loss contingencies, management considers the likelihood of loss as well as the ability to reasonably estimate the amount of such loss or liability. An estimated loss is recorded when it is considered probable that such a liability has been incurred and when the amount of loss can be reasonably estimated. As litigation is subject to inherent uncertainties, we cannot be certain that we will prevail in these matters. However, we do not believe that the ultimate outcome of any pending matters will have a material adverse effect on our consolidated financial position, results of operations or cash flows.

Business Combinations [Abstract]

Business Combinations

NOTE 12 – BUSINESS COMBINATIONS

As part of our ongoing strategy to increase market share in certain markets, we completed multiple business combinations during each of the years ended December 31, 2015, 2014 and 2013. The goodwill to be recognized in conjunction with these business combinations is attributable to expected improvement in the business of these acquired companies. We estimate approximately $24.0 million of the goodwill resulting from the 2015 acquisitions is expected to be deductible for tax purposes.

2015

On March 12, 2015, we acquired 100% of the stock and membership interests of nine different legal entities, collectively referred to as BDI Insulation (“BDI”). The purchase price consisted of cash of $30.7 million and seller obligations of $5.8 million. Revenue and net income since the date of acquisition included in our Consolidated Statement of Operations for the year ended December 31, 2015 were $32.5 million and $2.0 million, respectively.

On April 6, 2015, we acquired 100% of the common stock of C.Q. Insulation Inc. (“CQ”). The purchase price consisted of cash of $5.2 million and seller obligations of $2.3 million, of which approximately $1.8 million was contingent upon certain requirements of the seller. All requirements were met and the full amount was paid during the year ended December 31, 2015.

On August 10, 2015, we acquired 100% of the common stock of Eastern Contractor Services (“Eastern”). The purchase price consisted of cash of $24.2 million and seller obligations of $2.9 million. Revenue and net income since the date of acquisition included in our Consolidated Statement of Operations for the year ended December 31, 2015 were $7.4 million and $0.3 million, respectively.

On November 9, 2015, we acquired substantially all of the assets of Sierra Insulation Contractors, Inc. (“Sierra”) and Eco-Tect Insulation, Inc. (“Eco-Tect”). The purchase price consisted of cash of $3.2 million and seller obligations of $0.5 million. Revenue and net income since the date of acquisition included in our Consolidated Statement of Operations for the year ended December 31, 2015 were $0.8 million and $40 thousand, respectively.

On November 10, 2015, we acquired substantially all of the assets of Overhead Door Company of Burlington (“Overhead Door”). The purchase price consisted of cash of $5.1 and seller obligations of $0.1 million. Revenue and net income since the date of acquisition included in our Consolidated Statement of Operations for the year ended December 31, 2015 were $1.0 million and $14 thousand, respectively.

The purchase price consisted of cash of $4.7 million and seller obligations of $0.5 million. Revenue and net income since the date of acquisition included in our Consolidated Statement of Operations for the year ended December 31, 2015 were $0.6 million and $20 thousand, respectively.

2014

On March 24, 2014, we acquired 100% of the common stock of U.S. Insulation Corp. (“U.S. Insulation”). The purchase price consisted of cash of $2.0 million and seller obligations of $0.3 million. Revenue and net income since the date of acquisition included in our Consolidated Statement of Operations for the year ended December 31, 2014 were $9.7 million and $0.8 million, respectively.

(“Ace”) and on November 1, 2013 we acquired 100% of the membership interest of KMB Contracting Services, Inc. (“KMB”). The purchase price of our 2013 acquisitions consisted of cash of $1.2 million and a seller obligation for $0.4 million. We combined Ace and KMB with existing branches upon acquisition and as such, we are unable to differentiate the results of operations between Ace, KMB, and the existing branches for the year ended December 31, 2013.

The estimated fair values of the assets acquired and liabilities assumed for the acquisitions, as well as total purchase prices and cash paid, approximated the following (in thousands):

Goodwill and Intangibles, net per the above table do not agree to the total gross increases of these assets, as shown in Note 4—Goodwill and Intangibles, to our audited consolidated financial statements included in this Form 10-K for the Company. Goodwill and intangibles, net for the Company were increased due to a small tuck-in acquisition and therefore do not appear in the above table. Intangibles, net also increased for other minor intangible assets added during the ordinary course of business.

The fair value of the net assets acquired, including identifiable intangible assets, relating to one of the business combinations included within the “Other” column in the above table was approximately $4.8 million, which exceeds the purchase price of $3.7 million. Accordingly, we recognized the excess of the fair value of the net assets acquired over purchase price paid of approximately $1.1 million as a gain on bargain purchase. The gain on bargain purchase was included in Other income in our Consolidated Statements of Operations. Prior to recognizing the gain, we reassessed the fair value of the assets acquired and liabilities assumed in the business combination including consultation with our external valuation experts. Assets were valued using the same methodology as our other business combinations, including the use of a discounted cash flow model as well as several other factors. We believe we were able to acquire this entity for less than the fair value of its net assets due to an absence of multiple bidders combined with the significant improvement of our purchasing power.

The provisional amounts for BDI originally reported in our Condensed Consolidated Balance Sheets included in our Quarterly Report on Form 10-Q for the period ended March 31, 2015 were adjusted to reflect the review and ongoing analysis of the fair value measurements. As a result of an independent appraisal, we increased goodwill by approximately $1.4 million and our seller obligations by approximately $0.3 million for an adjustment to the fair value of a working capital contingent liability. These adjustments, as well as various other insignificant adjustments, resulted in a total purchase price increase for BDI of approximately $0.3 million as reflected within the above table and were within applicable measurement period guidelines.

The provisional amounts for CQ originally reported in our Condensed Consolidated Balance Sheets included in our Quarterly Report on Form 10-Q for the period ended June 30, 2015 were adjusted to reflect the review and ongoing analysis of the fair value measurements. As a result of an independent appraisal, we increased goodwill by approximately $0.5 million and our seller obligations by approximately $0.3 million for an adjustment to the fair value of a contingent consideration liability. These adjustments, as well as various other insignificant adjustments, resulted in a total purchase price increase for CQ of approximately $0.5 million as reflected within the above table and were within applicable measurement period guidelines.

Further adjustments to the allocation for all acquisitions described above are expected as third-party or internal valuations are finalized, certain tax aspects of the transaction are completed, and customary post-closing reviews are concluded during the measurement period attributable to each individual business combination. As a result, additional minor 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.

Included in other noncurrent assets in the above table as of the year ended December 31, 2015 is an insurance receivable of $2.0 million and an indemnification asset associated with the acquisition of BDI in the amount of $1.7 million. These assets offset equal liabilities included in other long-term liabilities in the above table, which represent additional insurance reserves and an uncertain tax position liability for which we may be liable. All amounts are measured at their acquisition date fair value.

Estimates of acquired intangible assets related to the acquisitions are as follows (dollars in thousands):


	2015				2014				2013
Acquired intangibles assets	Estimated Fair Value		Weighted Average Estimated Useful Life (yrs)		Estimated Fair Value		Weighted Average Estimated Useful Life (yrs)		Estimated Fair Value		Weighted Average Estimated Useful Life (yrs)

Pro Forma Information (unaudited)

The unaudited pro forma information has been prepared as if the 2015 acquisitions had taken place on January 1, 2014, the 2014 acquisitions had taken place on January 1, 2013 and the 2013 acquisitions had taken place on January 1, 2012. The unaudited pro forma information is not necessarily indicative of the results that we would have achieved had the transactions actually taken place on January 1, 2014 and 2013, and the unaudited pro forma information does not purport to be indicative of future financial operating results (in thousands, except for per share data).


	Pro Forma for the years ended December 31,
	2015		2014			2013
Net revenue	$	710,438	$	637,434		$	459,195
Net income	$	28,083	$	15,219		$	6,811
Accretion charges on Series A Redeemable Preferred Stock		—		(19,897	)		(6,223	)

Net income (loss) attributable to common stockholders	$	28,083	$	(4,678	)	$	588
Net income (loss) per share attributable to common stockholders (basic and diluted)	$	0.90	$	(0.16	)	$	0.03

Pro forma data for Parker Insulation and Building Products (“Parker”), a subsidiary of Eastern, is not included in the above table. Results for Parker represent an insignificant portion of the financial data of Eastern as a whole. We were unable to obtain complete financial data prior to the date of acquisition despite reasonable efforts. As a result, only financial information since the date of acquisition is included.

Unaudited pro forma net income has been calculated after adjusting our consolidated results to reflect additional intangible asset amortization expense of $3.3 million, $6.8 million and $0.6 million for the years ended December 31, 2015, 2014 and 2013, respectively. In addition, unaudited pro forma net income includes income tax effects of $0.9 million and $0.8 million for the years ended December 31, 2015 and 2014, respectively. We included approximately $1.0 million in transaction costs incurred by a seller resulting from a business combination occurring in the year ended December 31, 2015 in earnings for the year ended December 31, 2014 as though the acquisition occurred as of the beginning of the comparable period.

- Definition

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).

Discontinued Operations

NOTE 13 – DISCONTINUED OPERATIONS

During the years ended December 31, 2015 and 2014, we did not discontinue operations in any of our markets since no closures representing a strategic shift in operations were made. During the year ended December 31, 2013, we made the decision to close our branches in Oklahoma City, Oklahoma and Williston, North Dakota along with our distribution facility in Hebron, Ohio. We have presented the operations of these closed branches as discontinued operations in the Consolidated Statements of Operations for the years ended December 31, 2015, 2014 and 2013.

All closures made during the year ended December 31, 2013 were made in order to optimize capital and resource allocations and enhance our financial position. We have no continuing involvement with or cash flows from the closed branches. Further, the customers associated with closed branches and other discontinued operations will not be served by other branches. A summary of operations we discontinued in these markets for the years ended December 31, 2015, 2014 and 2013 is as follows (in thousands):

Income (Loss) Per Common Share

NOTE 14 – INCOME (LOSS) PER COMMON SHARE

Basic net income (loss) per common share is calculated by dividing net income (loss) attributable to common stockholders by the weighted average shares outstanding during the period, without consideration for common stock equivalents.

Diluted net income (loss) 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 (loss) per common share calculation when dilutive. Basic and diluted income (loss) per common share was as follows (in thousands, except share and per share data):

Subsequent Events [Abstract]
Subsequent Events	NOTE 15 – SUBSEQUENT EVENTS Business Combination On January 25, 2016, we acquired substantially all of the assets of Key Green Builder Services, LLC d/b/a Key Insulation for total consideration of approximately $5.6 million, subject to a working capital adjustment. The initial accounting for the business combination was not complete at the time the financial statements were issued due to the timing of the acquisition and the filing of this Annual Report on Form 10-K. As a result, disclosures required under ASC 805-10-50, Business Combinations, cannot be made at this time. On February 2, 2016, we acquired substantially all of the assets of Marshall Insulation, LLC for total consideration of approximately $1.0 million, subject to a working capital adjustment. The initial accounting for the business combination was not complete at the time the financial statements were issued due to the timing of the acquisition and the filing of this Annual Report on Form 10-K. As a result, disclosures required under ASC 805-10-50, Business Combinations, cannot be made at this time. On February 29, 2016, we acquired substantially all of the assets of Kern Door Company for total consideration of approximately $3.1 million, subject to a working capital adjustment. The initial accounting for the business combination was not complete at the time the financial statements were issued due to the timing of the acquisition and the filing of this Annual Report on Form 10-K. As a result, disclosures required under ASC 805-10-50, Business Combinations, cannot be made at this time. New Credit Facility On February 29, 2016, we entered into the Credit and Security Agreement with the lenders named therein and KeyBank National Association, as joint lead arranger, sole book runner, administrative agent, swing line lender and issuing lender. The Credit and Security Agreement amends and restates the Prior Credit and Security Agreement, which was scheduled to mature in April 2020. We used a portion of the funds from the Credit and Security Agreement to pay off the outstanding balances under our previous credit agreement. The Credit and Security Agreement provides for a five-year senior secured credit facility in an aggregate principal amount of up to $325.0 million, exclusive of the available accordion feature, consisting of a $100.0 million revolving line of credit (the “Revolving LOC”), a $100.0 million term loan (the “Term Loan”), which was borrowed at closing, and a delayed draw term loan facility (the “Delayed Draw Term Loan Facility”) providing for up to $125.0 million in additional term loan draws during the first year of the Credit and Security Agreement. Under the Revolving LOC, up to an aggregate of $20.0 million will be available to us for the issuance of letters of credit and up to an aggregate of $5.0 million will be available to us for swing line loans. The Credit and Security Agreement also includes an accordion feature which allows us, at our option but subject to lender and certain other approvals, to add up to an aggregate of $75.0 million in principal amount of term loans or additional revolving credit commitments, subject to the same terms as the Revolving LOC and Term Loan. As of February 29, 2016, there were approximately $12.3 million in letters of credit issued and no other borrowings outstanding under the Revolving LOC, and no borrowings under the Delayed Draw Term Loan Facility. The Term Loan amortizes in quarterly principal payments of $1.1 million starting on June 30, 2016, with the quarterly payment amount increasing to $2.5 million through December 31, 2020. Draws under the Delayed Draw Term Loan Facility convert to an amortizing term loan (the “DDTL Term Loan”) on the earlier of (1) the date the Delayed Draw Term Loan Facility is fully drawn and (2) February 28, 2017, when it will begin to amortize in quarterly principal payments equal (on a percentage basis) to the then-current amortization rate on the Term Loan. Draws under the Delayed Draw Term Loan Facility may be used only for acquisitions or major capital expenditures. In addition to scheduled amortization payments, if our leverage ratio for any fiscal year is greater than or equal to 3.00 to 1.00, we would be required to make additional payments on the Term Loan and DDTL Term Loan for such fiscal year in an amount of not less than 50% of our excess cash flow (as defined in the Credit and Security Agreement) for such fiscal year within 10 days of our delivery of the financial reports required under the Credit and Security Agreement. Any remaining unpaid balances of the Term Loan or the DDTL Term Loan Facility are due on February 28, 2021 (the “Maturity Date”). Loans under the Credit and Security Agreement bear interest at either the eurodollar rate or the base rate, at our election, plus a margin based on the type of rate applied and the value (represented as a ratio) of our total debt to earnings. In addition to interest, we are required to pay commitment fees on the unused portion of the Revolving LOC. The commitment fee rate for the period from February 29, 2016 through August 31, 2016, will be 0.225%. Thereafter, the commitment fee rate, like the interest rate spreads, is subject to adjustment based on our leverage ratio, with possible future commitment fees ranging from 0.200% to 0.300% per annum. We are also required to pay a ticking fee of 0.375% per annum on the unused portion of the Delayed Draw Term Loan Facility until it is borrowed or the end of the Delayed Draw Term Loan Facility period on February 28, 2017. All of the obligations under the Credit and Security Agreement will be guaranteed by our existing and future direct and indirect material domestic subsidiaries, other than Suburban Insulation, Inc. (the “Guarantors”). Subject to certain restrictions, all of our and each Guarantor’s obligations under the Credit and Security Agreement are secured by: (1) all of our and each Guarantor’s tangible and intangible personal property and real property, excluding those assets pledged under capital leases and capital equipment loans; (2) a pledge of, and first priority perfected lien on, 100% of the capital stock or other equity interests of our and each Guarantor’s domestic subsidiaries; and (3) a negative pledge on all of our and each Guarantor’s assets. The Credit and Security Agreement contains covenants (as defined in the Credit and Security Agreement) that require us, commencing with the first quarter ending June 30, 2016, to (1) maintain a fixed charge coverage ratio of not less than 1.10 to 1.0 and (2) maintain a leverage ratio of no greater than (a) 3.50 to 1.00 through December 30, 2016; (b) 3.25 to 1.00 on December 31, 2016 through June 29, 2017; (c) 3.00 to 1.00 on June 30, 2017 through December 30, 2017; (d) 2.75 to 1.00 on December 31, 2017 through June 29, 2018; and (e) 2.50 to 1.00 on June 30, 2018 and thereafter. The Credit and Security Agreement also contains various restrictive non-financial covenants and a provision that, upon an event of default (as defined by the Credit and Security Agreement), amounts outstanding under the Credit and Security Agreement would bear interest at the rate as determined above plus 2.0%.

(a)

Net loss attributable to common stockholders for the quarter ended March 31, 2014 included approximately $19.9 million of accretion of Redeemable Preferred Stock to its redemption value at the time of our IPO. Prior to the redemption, we accounted for the difference between the carrying amount of the Redeemable Preferred Stock and the redemption amount by increasing the carrying amount for the periodic accretion which reduces net income to arrive at net loss attributable to common stockholders.

Earnings-per-share amounts are computed independently each quarter for net income from continuing operations attributable to common stockholders and net income (loss) attributable to common stockholders. As a result, the sum of each quarter’s per-share amount may not equal the total per-share amount for the respective year, and the sum of per-share amounts from continuing operations and discontinued operations may not equal the total per-share amounts for net loss attributable to common stockholders for the respective quarters.

Estimated Fair Value of Financial Instruments

Accounts receivable, accounts payable, and accrued liabilities as of December 31, 2015 and 2014 approximate their fair value due to the short-term maturities of these financial instruments. The carrying amounts of the long-term debt, including the term loan, delayed draw term loan and revolving credit facility, under the Prior Credit Agreement and the Term Loan, Delayed Draw Term Loan Facility and Revolving LOC under the new Credit and Security Agreement approximate their fair values as of December 31, 2015 and 2014 due to the short term maturities of the underlying variable rate LIBOR agreements. The carrying amount of the obligations associated with our capital leases approximate fair value as of December 31, 2015 and 2014 because the associated assets generate sufficient cash to settle the obligations. All debt classifications represent value measurements.

Credit facility, amortization description	The Term Loan amortizes in quarterly principal payments of $1.1 million starting on June 30, 2016, with the quarterly payment amount increasing to $2.5 million through December 31, 2020. Draws under the Delayed Draw Term Loan Facility convert to an amortizing term loan (the “DDTL Term Loan”) on the earlier of (1) the date the Delayed Draw Term Loan Facility is fully drawn and (2) February 28, 2017, when it will begin to amortize in quarterly principal payments equal (on a percentage basis) to the then-current amortization rate on the Term Loan. Draws under the Delayed Draw Term Loan Facility may be used only for acquisitions or major capital expenditures. In addition to scheduled amortization payments, if our leverage ratio for any fiscal year is greater than or equal to 3.00 to 1.00, we would be required to prepay the Term Loan and DDTL Term Loan for such fiscal year in an amount of not less than 50% of our excess cash flow for such fiscal year within 10 days of our delivery of the financial reports required under the Credit and Security Agreement. Any remaining unpaid balances of the Term Loan or the DDTL Term Loan Facility are due on February 28, 2021 (the “Maturity Date”).
