Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Principles of Consolidation The consolidated financial statements present the results of operations, financial position, and cash flows of Builders FirstSource, Inc. and its wholly-owned subsidiaries. All intercompany transactions have been eliminated in consolidation. Accounting Estimates The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates. Estimates are used when accounting for items such as revenue, vendor rebates, allowance for returns, discounts and doubtful accounts, employee compensation programs, depreciation and amortization periods, income taxes, inventory values, insurance programs, goodwill, other intangible assets and long-lived assets. Sales Recognition We recognize sales of building products upon delivery to the customer. For contracts with service elements, sales are generally recognized on the completed contract method as these contracts are usually completed within 30 days with the percentage of completion method applied on a limited basis to certain contracts. Percentage of completion revenue represents less than 2% of our consolidated sales for each year presented. Contract costs include all direct material and labor, equipment costs and those indirect costs related to contract performance. Provisions for estimated losses on uncompleted contracts are recognized in the period in which such losses are determined. Prepayments for materials or services are deferred until such materials have been delivered or services have been provided. All sales recognized are net of allowances for discounts and estimated returns, based on historical experience. We present all sales tax on a net basis in our consolidated financial statements. The Company records sales incentives provided to customers as a reduction of revenue. Cash and Cash Equivalents & Checks Outstanding Cash and cash equivalents consist of cash on hand and all highly liquid investments with an original maturity date of three months or less. Also included in cash and cash equivalents are proceeds due from credit card transactions that generally settle within two business days. We maintain cash at financial institutions in excess of federally insured limits. Further, we maintain various banking relationships with different financial institutions. Accordingly, when there is a negative book cash balance resulting from outstanding checks that had not yet been paid by any single financial institution; they are reflected in checks outstanding on the accompanying consolidated balance sheets. Financial Instruments We use financial instruments in the normal course of business as a tool to manage our assets and liabilities. We do not hold or issue financial instruments for trading purposes. We issued detachable warrants in 2011, which were measured at fair value on a recurring basis until exercised in 2015 as discussed in Note 8. Accounts Receivable We extend credit to qualified professional homebuilders and contractors, in many cases on a non-collateralized basis. Accounts receivable potentially expose us to concentrations of credit risk. Because our customers are dispersed among our various markets, our credit risk to any one customer or state economy is not significant. Our customer mix is a balance of large national homebuilders, regional homebuilders, local homebuilders and repair and remodeling contractors. For the year ended December 31, 2016, our top 10 customers accounted for approximately 16.8% of our sales, and no single customer accounted for more than 5% of sales. The allowance for doubtful accounts is based on management’s assessment of the amount which may become uncollectible in the future and is estimated using specific review of problem accounts, overall portfolio quality, current economic conditions that may affect the borrower’s ability to pay, and historical experience. Accounts receivable are written off when deemed uncollectible. Other receivables consist primarily of vendor rebates receivable. We also establish reserves for credit memos and customer returns. The reserve balance was $5.6 million and $3.8 million at December 31, 2016 and 2015, respectively. The activity in this reserve was not significant for each year presented. Accounts receivable consisted of the following at December 31: 2016 2015 (In thousands) Accounts Receivable $ 580,779 $ 536,593 Less: allowances for returns and doubtful accounts 11,571 8,049 Accounts receivable, net $ 569,208 $ 528,544 The following table shows the changes in our allowance for doubtful accounts: 2016 2015 2014 (In thousands) Balance at January 1, $ 4,245 $ 1,734 $ 2,413 Additions 1,390 2,285 (274 ) Deductions (write-offs, net of recoveries) 287 226 (405 ) Balance at December 31, $ 5,922 $ 4,245 $ 1,734 Inventories Inventories consist principally of materials purchased for resale, including lumber, sheet goods, windows, doors and millwork, as well as certain manufactured products and are stated at the lower of cost or market. Cost is determined using the weighted average method, the use of which approximates the first-in, first-out method. We accrue for shrink based on the actual historical shrink results of our most recent physical inventories adjusted, if necessary, for current economic conditions. These estimates are compared with actual results as physical inventory counts are taken and reconciled to the general ledger. During the year, we monitor our inventory levels by market and record provisions for excess inventories based on slower moving inventory. We define potential excess inventory as the amount of inventory on hand in excess of the historical usage, excluding special order items purchased in the last six months. We then apply our judgment as to forecasted demand and other factors, including liquidation value, to determine the required adjustments to net realizable value. Our inventories are generally not susceptible to technological obsolescence. Our arrangements with vendors provide for rebates of a specified amount of consideration, payable when certain measures, generally related to a stipulated level of purchases, have been achieved. We account for estimated rebates as a reduction of the prices of the vendor’s inventory until the product is sold, at which time such rebates reduce cost of sales in the accompanying consolidated statements of operations and comprehensive loss. Throughout the year we estimate the amount of the rebates based upon the expected level of purchases. We continually revise these estimates based on actual purchase levels. We source products from a large number of suppliers. No materials purchased from any single supplier represented more than 7% of our total materials purchased in 2016. Shipping and Handling Costs Handling costs incurred in manufacturing activities are included in cost of sales. All other shipping and handling costs are included in selling, general and administrative expenses in the accompanying consolidated statements of operations and comprehensive income (loss) and totaled $269.8 million, $171.9 million and $79.7 million in 2016, 2015 and 2014, respectively. Income Taxes We account for income taxes utilizing the liability method described in the Income Taxes Warranty Expense We have warranty obligations with respect to most manufactured products; however, the liability for the warranty obligations is not significant as a result of third-party inspection and acceptance processes. Debt Issuance Costs and Debt Discount Loan costs are capitalized upon the issuance of long-term debt and amortized over the life of the related debt. Debt issuance costs associated with term debt are presented as a reduction to long-term debt. Debt issuance costs associated with revolving debt arrangements are presented as a component of other assets. Debt issuance costs incurred in connection with revolving debt arrangements are amortized using the straight-line method. Debt issuance costs incurred in connection with term debt are amortized using the effective interest method. Debt discount is amortized over the life of the related debt using the effective interest method. Amortization of debt issuance costs and the debt discount are included in interest expense. Upon changes to our debt structure, we evaluate debt issuance costs in accordance with the Debt Property, Plant and Equipment Property, plant and equipment are recorded at cost and depreciated using the straight-line method over the estimated useful lives of the assets. The estimated lives of the various classes of assets are as follows: Buildings and improvements 20 to 40 years Machinery and equipment 3 to 10 years Furniture and fixtures 3 to 5 years Leasehold improvements The shorter of the estimated useful life or the remaining lease term Major additions and improvements are capitalized, while maintenance and repairs that do not extend the useful life of the property are charged to expense as incurred. Gains or losses from dispositions of property, plant and equipment are recorded in the period incurred. We also capitalize certain costs of computer software developed or obtained for internal use, including interest, provided that those costs are not research and development, and certain other criteria are met. Internal use computer software costs are included in machinery and equipment and generally depreciated using the straight-line method over the estimated useful lives of the assets, generally three years. We periodically evaluate the commercial and strategic operation of the land, related buildings and improvements of our facilities. In connection with these evaluations, some facilities may be consolidated, and others may be sold or leased. Nonoperating assets primarily related to land and building real estate assets associated with location closures that are actively being marketed for sale within a year are classified as assets held for sale and recorded at fair value, usually the quoted market price obtained from an independent third-party less the cost to sell. Until the assets are sold, an estimate of the fair value is reassessed at each reporting period. Net gains or losses related to the sale of real estate and equipment or impairment adjustments related to assets held for sale are recorded as selling, general and administrative expenses. Long-Lived Assets We evaluate our long-lived assets, other than goodwill, for impairment when events or changes in circumstances indicate, in our judgment, that the carrying value of such assets may not be recoverable. The determination of whether or not impairment exists is based on our estimate of undiscounted future cash flows before interest attributable to the assets as compared to the net carrying value of the assets. If impairment is indicated, the amount of the impairment recognized is determined by estimating the fair value of the assets based on estimated discounted future cash flows and recording a provision for loss if the carrying value is greater than estimated fair value. The net carrying value of assets identified to be disposed of in the future is compared to their estimated fair value, usually the quoted market price obtained from an independent third-party less the cost to sell, to determine if impairment exists. Until the assets are disposed of, an estimate of the fair value is reassessed when related events or circumstances change. Asset impairment charges are presented in the consolidated statements of operations and comprehensive income (loss) for the respective years. Insurance We have established insurance programs to cover certain insurable risks consisting primarily of physical loss to property, business interruptions resulting from such loss, workers’ compensation, employee healthcare, and comprehensive general and auto liability. Third party insurance coverage is obtained for exposures above predetermined deductibles as well as for those risks required to be insured by law or contract. Provisions for losses are developed from valuations that rely upon our past claims experience, which considers both the frequency and settlement of claims. We discount our workers’ compensation liability based upon estimated future payment streams at our risk-free rate. Our total insurance reserve balances were $80.4 million and $84.3 million as of December 31, 2016 and 2015, respectively. Of these balances $43.6 million and $40.3 million were recorded as other long-term liabilities as of December 31, 2016 and 2015, respectively. Included in these reserve balances as of December 31, 2016 and 2015, were approximately $9.4 million and $9.9 million, respectively, of claims that exceeded stop-loss limits and are expected to be recovered under insurance policies which are also recorded as other receivables and other assets in the accompanying consolidated balance sheets. Net Income (Loss) per Common Share Net income (loss) per common share, or earnings per share (“EPS”), is calculated in accordance with the Earnings per Share The table below presents a reconciliation of weighted average common shares used in the calculation of basic and diluted EPS for the years ended December 31: 2016 2015 2014 (In thousands) Weighted average shares for basic EPS 110,754 103,190 98,050 Dilutive effect of options, warrants, and RSUs 2,831 — 2,472 Weighted average shares for diluted EPS 113,585 103,190 100,522 Our restricted stock shares include rights to receive dividends that are not subject to the risk of forfeiture even if the underlying restricted stock shares on which the dividends were paid do not vest. In accordance with the Earnings Per Share For the purpose of computing diluted EPS, weighted average shares outstanding have been adjusted for common shares underlying 3,515,000 options to purchase common stock and 2,177,000 restricted stock units (“RSUs”) for 2016. Options to purchase 4,998,000 shares of common stock and 1,516,000 RSUs were not included in the computation of diluted EPS for 2015 because their effect was anti-dilutive. Incremental shares attributable to average warrants outstanding during 2015 were not included in the computation of diluted EPS for 2015 as their effect was anti-dilutive. There were no warrants outstanding at December 31, 2016 as all of the remaining warrants were exercised in April 2015. Weighted average shares outstanding have been adjusted for common shares underlying 6,246,000 options, 700,000 warrants, and 1,855,000 RSUs for 2014. In addition, $0.5 million of income due to fair value adjustments related to the warrants was excluded from net income in the computation of diluted EPS for 2014. Goodwill and Other Intangible Assets Intangibles subject to amortization We recognize an acquired intangible asset apart from goodwill whenever the intangible asset arises from contractual or other legal rights, or whenever it can be separated or divided from the acquired entity and sold, transferred, licensed, rented, or exchanged, either individually or in combination with a related contract, asset or liability. Impairment losses are recognized if the carrying value of an intangible asset subject to amortization is not recoverable from expected future cash flows and its carrying amount exceeds its estimated fair value. Goodwill We recognize goodwill as the excess cost of an acquired entity over the net amount assigned to assets acquired and liabilities assumed. Goodwill is tested for impairment on an annual basis and between annual tests whenever impairment is indicated. This annual test takes place as of December 31 each year. Impairment losses are recognized whenever the implied fair value of goodwill is less than its carrying value. Stock-based Compensation We have four stock-based employee compensation plans, which are described more fully in Note 10. We issue new common stock shares upon exercises of stock options, grants of restricted stock, and vesting of RSUs. The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions for the year ended December 31: 2016 2015 2014 Expected life 6.0 years 6.0 years 5.8 years Expected volatility 60.88% 75.2% 92.1% Expected dividend yield 0.00% 0.00% 0.00% Risk-free rate 1.41% 1.75% 1.83% The expected life represents the period of time the options are expected to be outstanding. We used the simplified method for determining the expected life assumption due to limited historical exercise experience on our stock options. The expected volatility is based on the historical volatility of our common stock over the most recent period equal to the expected life of the option. The expected dividend yield is based on our history of not paying regular dividends in the past and our current intention to not pay regular dividends in the foreseeable future. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant and has a term equal to the expected life of the options. The fair value of RSU awards subject to market conditions is estimated on the date of grant using the Monte Carlo simulation model with the following weighted average assumptions for the year ended December 31: 2016 Expected volatility (company) 53.6% Expected volatility (peer group median) 17.3% Correlation between the company and peer group median 0.47 Expected dividend yield 0.00% Risk-free rate 1.29% The expected volatilities are based on the historical volatilities of our common stock and the common stocks of the constituents of the Company’s peer group over the most recent period equal to the measurement period. The expected dividend yield is based on our history of not paying regular dividends in the past and our current intention to not pay regular dividends in the foreseeable future. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant and has a term equal to the measurement period. We did not grant any RSUs subject to market conditions in 2015 or 2014. Fair Value The Fair Value Measurements and Disclosures Level 1 — unadjusted quoted prices for identical assets or liabilities in active markets accessible by us Level 2 — inputs that are observable in the marketplace other than those inputs classified as Level 1 Level 3 — inputs that are unobservable in the marketplace and significant to the valuation If a financial instrument uses inputs that fall in different levels of the hierarchy, the instrument will be categorized based upon the lowest level of input that is significant to the fair value calculation. The only financial instruments measured at fair value on a recurring basis were our warrants as discussed in Note 8. As of December 31, 2016 and 2015 the Company does not have any financial instruments which are measured at fair value on a recurring basis. We have elected to report the value of our 10.75% senior unsecured notes due 2023 (“2023 notes”), 5.625% senior secured notes due 2024 (“2024 notes”), and $600.0 million term loan facility due 2022 (“2015 term loan”) at amortized cost. The fair values of the 2023 notes, the 2024 notes and the 2015 term loan at December 31, 2016 were approximately $421.8 million, $758.0 million and $471.2 million, respectively, and were determined using Level 2 inputs based on market prices.

Timber Tech is based in Cibolo, Texas, which is approximately 25 miles northeast of downtown San Antonio. Timber Tech is a manufacturer of roof trusses, floor trusses, wall panels and sub-components, as well as a supplier of glue laminated timber and veneer lumber beams. On July 31, 2015, the Company acquired all of the operating affiliates of ProBuild through the purchase of all issued and outstanding equity interests in ProBuild for $1.63 billion in cash, subject to certain adjustments. The purchase price was funded by the net proceeds received from the financing transactions described in Note 8. Previously headquartered in Denver, Colorado, ProBuild is one of the nation’s largest professional building materials suppliers. As a result of the ProBuild acquisition, the Company has a greater diversification of products and services and a significantly improved geographic footprint. These acquisitions were accounted for by the acquisition method, and accordingly the results of operations were included in the Company’s consolidated financial statements from the acquisition date. The purchase price was allocated to the assets acquired based on estimated fair values at the acquisition date, with the excess of purchase price over the estimated fair value of the net assets acquired recorded as goodwill. The fair value of acquired intangible assets of $184.5 million, primarily related to tradenames, customer relationships and lease contract intangibles, was estimated by applying an income approach. That measure is based on significant Level 3 inputs not observable in the market. Key assumptions developed based on the Company’s historical experience, future projections and comparable market data include future cash flows, long-term growth rates, royalty rates, attrition rates and discount rates. We incurred acquisition related costs of $20.9 million and $0.6 million related to these acquisitions during the years ended December 31, 2015 and 2014, respectively. These costs include due diligence costs and transaction costs to complete the acquisitions, and have been recognized in selling, general and administrative expense in the accompanying condensed consolidated statements of operations and comprehensive income (loss). We did not incur any acquisition costs related to these acquisitions during the year ended December 31, 2016. The following table summarizes the aggregate fair values of the assets acquired and liabilities assumed for ProBuild and all other acquisitions, net of cash (in thousands) for the year ended: 2015 2014 ProBuild All Other All Other Accounts receivable $ 470,105 $ 306 $ 9,544 Other receivables 34,718 — — Inventory 411,160 1,095 5,417 Other current assets 12,101 — — Property, plant and equipment 658,540 3,961 8,580 Assets held for sale 10,911 — — Goodwill (Note 5) 602,690 (2,839 ) 28,581 Intangible assets (Note 6) 184,509 3,311 17,467 Other assets 2,016 — 34 Total assets acquired 2,386,750 5,834 69,623 Checks outstanding (32,378 ) — — Current maturities of long term debt and lease obligations (25,456 ) — — Accounts payable (339,673 ) — — Accrued liabilities (210,436 ) (37 ) (286 ) Other long-term liabilities (53,703 ) — — Long-term debt and lease obligations, net of current maturities (262,390 ) — — Total liabilities assumed (924,036 ) (37 ) (286 ) Total net assets acquired $ 1,462,714 $ 5,797 $ 69,337 All of the goodwill and intangible assets recognized from the ProBuild and all other acquisitions are expected to be deductible for tax purposes, with the goodwill recognized from these acquisitions being amortized ratably over a 15 year period. The ProBuild acquisition was treated as an asset purchase for tax purposes. The operating results of the acquisitions have been included in the consolidated statements of operations and comprehensive income (loss) from their acquisition dates through December 31, 2016. Net sales and net income attributable to ProBuild were approximately $4,520 million and $190 million, respectively for the year ended December 31, 2016. Net sales and net income attributable to ProBuild were approximately $1,860 million and $50 million, respectively, for the period of August 1, 2015 through December 31, 2015. Net income attributable to ProBuild does not include an allocation of the additional interest expense incurred by the Company as a result of the ProBuild acquisition financing transactions. Net sales and net income attributable to the other acquisitions are not material, individually or in the aggregate. The following table reflects the pro forma operating results for the Company which gives effect to the acquisition of ProBuild as if it had occurred on January 1, 2014. The pro forma results are based on assumptions that the Company believes are reasonable under the circumstances. The pro forma results are not necessarily indicative of future results. The pro forma financial information includes the historical results of the Company and ProBuild adjusted for certain items, which are described below, and does not include the effects of any synergies or cost reduction initiatives related to the acquisition of ProBuild. Pro forma information for the other acquisitions is not presented as it is not material, individually or in the aggregate. Year Ended December 31, 2015 2014 (pro forma) (in thousands, except per share amounts) Net sales $ 6,066,792 $ 6,082,819 Net loss $ (10,433 ) $ (127,880 ) Basic net loss per share $ (0.10 ) $ (1.19 ) Diluted net loss per share $ (0.10 ) $ (1.19 ) Pro forma net loss for the years ended December 31, 2015 and 2014 reflects adjustments primarily related to depreciation and amortization, the conversion from last-in, first-out to first-in, first out inventory valuation, and interest expense. Pro forma net loss for 2015 was adjusted to exclude transaction-related expenses of $46.9 million ($34.6 million incurred by the Company and $12.3 million incurred by ProBuild). Pro forma net loss for 2014 was adjusted to include these transaction-related expenses. Alaska Truss Acquisition On May 13, 2016, the Company acquired certain assets and the operations of Alaska Truss Manufacturing, LLC and ATM, LLC (collectively “Alaska Truss”) for cash of $4.0 million and $1.0 million of other consideration, subject to certain adjustments. Of the total consideration, $3.4 million was allocated to tangible assets acquired, primarily property, plant and equipment, $0.8 million was allocated to intangible assets and $0.8 million was allocated to goodwill. Based in Chugiak, Alaska, Alaska Truss supplies roof trusses to both residential and commercial contractors throughout the greater Anchorage area. Acquisition costs related to Alaska Truss were not material in the year ended December 31, 2016. Pro forma results of operations are not presented as this acquisition is not material.

In 2015, the change in the carrying amount of goodwill is attributable to our acquisitions of ProBuild and Timber Tech. The amount allocated to goodwill is attributable to the assembled workforce of the acquired companies as well as the diversification of products and services, the significantly improved geographic footprint, and the synergies expected to arise as a result of these acquisitions. We closely monitor trends in economic factors and their effects on operating results to determine if an impairment trigger was present that would warrant a reassessment of the recoverability of the carrying amount of goodwill prior to the required annual impairment test in accordance with the Intangibles – Goodwill and Other The process of evaluating goodwill for impairment involves the determination of fair value of our reporting units. Inherent in such fair value determinations are certain judgments and estimates relating to future cash flows, including our interpretation of current economic indicators and market valuations and assumptions about our strategic plans with regard to our operations. Due to the uncertainties associated with such estimates, actual results could differ from such estimates resulting in further impairment of goodwill. In performing our impairment analysis, we developed a range of fair values for our reporting units using a discounted cash flow methodology. The discounted cash flow methodology establishes fair value by estimating the present value of the projected future cash flows to be generated from the reporting unit. The discount rate applied to the projected future cash flows to arrive at the present value is intended to reflect all risks of ownership and the associated risks of realizing the stream of projected future cash flows. The discounted cash flow methodology uses our projections of financial performance for a five-year period. The most significant assumptions used in the discounted cash flow methodology are the discount rate, the terminal value and the expected future revenues, gross margins and operating expenses, which vary among reporting units. Significant assumptions used in our financial projections include housing starts, lumber commodity prices, and market share gains. We recorded no goodwill impairment charges in 2016, 2015, and 2014.

The purchase price was funded with the net cash proceeds from (i) the sale of $700.0 million in aggregate principal amount of 10.75% senior unsecured notes due 2023 (the “2023 notes”), (ii) entry into a $600.0 million term loan credit agreement (the “2015 term loan”) provided by a syndicate of financial institutions led by Deutsche Bank AG, New York Branch, as administrative and collateral agent, (iii) a $295.0 million draw on an amended and restated $800.0 million senior secured revolving credit facility (the “2015 facility”) provided by a syndicate of financial institutions led by SunTrust Bank as administrative and collateral agent, and (iv) a public offering of 9.2 million new shares of our common stock at an offering price of $12.80 per share (the “equity offering”). In connection with the financing transactions described above, we incurred approximately $65.0 million of various third-party fees and expenses. Of these costs, $18.1 million were allocated to the 2023 notes, $16.0 million were allocated to the 2015 term loan, $11.2 million were allocated to the 2015 facility and $6.5 million were allocated to the equity offering. The costs allocated to the 2023 notes and the 2015 term loan were recorded as reductions to long-term debt and are being amortized over their respective terms using the effective interest method. The costs allocated to the 2015 facility were recorded as other assets and are being amortized over its term on a straight-line basis. The costs allocated to the equity offering were recorded as a reduction to additional paid-in capital. In addition, $13.2 million in costs relate to commitment fees paid for bridge and backstop financing facilities entered into in connection with these financing transactions, neither of which was utilized. As such, these fees were recorded as interest expense in the third quarter of 2015. At the closing of these transactions, there were approximately $3.0 million in unamortized debt issuance costs associated with our previous revolving credit facility, of which approximately $0.9 million were recorded as interest expense in the third quarter of 2015. The remaining $2.1 million in unamortized costs associated with our previous revolving credit facility are being amortized over the term of the 2015 facility. 2016 Debt Transactions During the year ended December 31, 2016, the Company executed several debt transactions which are described in more detail below. These transactions include two debt exchanges, complete extinguishment of our 7.625% senior secured notes due 2021 (the “2021 notes”), repricing and partially repaying our 2015 term loan and a cash tender offer in which we further reduced the aggregate principal amount of outstanding 2023 notes. These transactions have extended our debt maturity profile and reduced our annual cash interest on a go forward basis. Note Exchange Transactions On February 12, 2016, we completed separate privately negotiated note exchange transactions in which $218.6 million in aggregate principal amount of our 2023 notes was exchanged for $207.6 million in aggregate principal amount of our previously outstanding 2021 notes. On February 29, 2016, we completed additional separate privately negotiated note exchange transactions in which $63.8 million in aggregate principal amount of our 2023 notes was exchanged for $60.0 million in aggregate principal amount of our previously outstanding 2021 notes. The note exchange transactions were considered to be debt extinguishments. As such, we recognized a net gain of $7.8 million which was recorded as an offset to interest expense in the accompanying consolidated statements of operations and comprehensive income (loss) for the year ended December 31, 2016. Of this $7.8 million gain, $14.8 million was attributable to the reduction in outstanding principal which was partially offset by the write-off of $7.0 million of unamortized debt issuance costs associated with the 2023 notes which were extinguished in the exchange transactions. In connection with issuance of the 2021 notes in the exchange transactions, we incurred $4.9 million of various third-party fees and expenses. These costs were previously recorded as a reduction to long-term debt and were subsequently written off to interest expense in the third quarter of 2016 in connection with the extinguishment of the 2021 notes as described in the “2016 Refinancing Transactions” section below. Note Redemption Transaction In May 2016, the Company exercised its contractual right to redeem $35.0 million in aggregate principal amount of 2021 notes at a price of 103.0%, plus accrued and unpaid interest. The redemption transaction was considered to be a debt extinguishment. As such, we recognized a loss of $1.7 million which was recorded as a component of interest expense in the accompanying consolidated statements of operations and comprehensive income (loss) for the year ended December 31, 2016. Of this $1.7 million loss, 2016 Refinancing Transactions In August 2016, we completed a private offering of $750.0 million in aggregate principal amount of 5.625% senior secured notes due 2024 (“2024 notes”) at an issue price equal to 100% of their face value. At the same time the Company also repriced its 2015 term loan. This repricing lowered the applicable margin to 3.75% in the case of Eurodollar loans and 2.75% in the case of base rate loans. This reduction represents a 1.25% decrease in the applicable margin for both Eurodollar and base rate loans. In connection with the repricing, the mandatory quarterly principal repayments were reduced from $1.375 million to $1.175 million. All other material terms of the 2015 term loan remain unchanged. The proceeds from the issuance of the 2024 notes were used, together with cash on hand and borrowings on the 2015 facility, to fully redeem the $582.6 million in aggregate outstanding principal amount of 2021 notes, to pay down $125.9 million of the 2015 term loan and to pay related transaction fees and expenses. The redemption of the 2021 notes was considered to be a debt extinguishment. As such, we recognized a loss of $43.9 million which was recorded as a component of interest expense in the accompanying consolidated statements of operations and comprehensive income (loss) for the year ended December 31, 2016. Of this $43.9 million loss, In connection with the issuance of the 2024 notes and the 2015 term loan repricing, we incurred approximately $12.0 million of various third-party fees and expenses. Of these costs $10.5 million were allocated to the 2024 notes and have been recorded as a reduction to long-term debt. These costs are being amortized over the contractual life of the 2024 notes using the effective interest method. The remaining $1.5 million in costs incurred were allocated to the 2015 term loan. Of this $1.5 million, $1.2 million was recorded to interest expense in the third quarter of 2016. The remaining $0.3 million of new third-party costs together with $10.9 million in remaining unamortized debt discount and debt issuance costs have been recorded as a reduction of long-term debt and are being be amortized over the remaining contractual life of the 2015 term loan using the effective interest method. Tender Offer In October 2016, we purchased $50.0 million in aggregate principal amount of our 2023 notes pursuant to the terms of a cash tender offer at a price of 117.0% of par value plus accrued and unpaid interest. The purchase of the 2023 notes was funded with cash on hand and borrowings under our 2015 facility. The tender offer transaction was considered to be a debt extinguishment. As such, we recognized a loss on extinguishment of $9.7 million which was recorded as a component of interest expense in the accompanying consolidated statements of operations and comprehensive income (loss) for the year ended December 31, 2016. Of this loss, approximately $8.5 million was attributable to the purchase premium paid to the lenders and $1.2 million was attributable to the write-off of unamortized debt issuance costs associated with the redeemed notes. In addition to the loss described above, we incurred approximately $0.1 million in third party costs which were recorded to selling, general, and administrative expense in the fourth quarter of 2016. Senior Unsecured Notes due 2023 As of December 31, 2016, we have $367.6 million outstanding in aggregate principal amount of the 2023 notes that mature on August 15, 2023. The 2023 notes were sold in a private offering at an issue price equal to 100% of their face value. Interest accrues on the 2023 notes at a rate of 10.75% per annum and is payable semi-annually on March 1 and September 1 of each year, commencing on March 1, 2016. The terms of the notes are governed by an indenture and a supplemental indenture, each dated as of July 31, 2015, among the Company, the guarantors named therein and Wilmington Trust, National Association, as trustee (the “trustee”). Pursuant to the indenture and supplemental indenture, the company’s significant operating subsidiaries serve as guarantors of the 2023 notes. The 2023 notes are the Company’s senior unsecured obligations and will rank equally with all of its existing and future senior unsecured debt and will be senior to all of its existing and future subordinated debt. The indenture contains certain restrictive covenants, which among other things, limit the ability of the Company to incur additional debt, issue preferred stock, create liens, pay dividends, make certain investments, sell certain assets, enter into certain types of transactions with affiliates, and effect mergers and consolidations. At any time prior to August 15, 2018, the Company may redeem the 2023 notes in whole or in part at a redemption price equal to 100% of the principal amount of the 2023 notes plus a premium as specified in the indenture. At any time on or after August 15, 2018, the Company may redeem the 2023 notes at the redemption prices set forth in the indenture plus accrued and unpaid interest. In addition, the Company may redeem up to 40% of the aggregate principal amount of the 2023 notes with the net cash proceeds of one or more equity offerings, as described in the indenture, at a price equal to 110.75% of the principal amount thereof, plus accrued and unpaid interest. In the event of a change in control, we may be required to repurchase all or part of the 2023 notes at a price equal to 101% of the principal amount thereof, plus accrued and unpaid interest. 2015 Term Loan Credit Agreement As of December 31, 2016, we have $467.7 million outstanding under the 2015 term loan, which matures on July 31, 2022. The 2015 term loan, which was issued at 99%, bears interest, at our option, at either a eurodollar rate or a base rate, plus, in each case an applicable margin. The margin will be 3.75% per annum in the case of eurodollar rate loans and 2.75% per annum in the case of base rate loans. The 2015 term loan has mandatory principal repayments of $1.175 million which are payable in March, June, September, and December of each year provided that each such payment is subject to reduction as a result of certain prepayments of the loans in accordance with the loan documentation. The weighted average interest rate of the term loan was 5.6% during the year ended December 31, 2016. 2015 Senior Secured Revolving Credit Facility The 2015 facility provides for an $800.0 million revolving credit line to be used for working capital and general corporate purposes. The available borrowing capacity, or borrowing base, is derived from a percentage of the Company’s eligible receivables and inventory, as defined by the agreement, subject to certain reserves. As of December 31, 2016, the net borrowing availability under the 2015 facility is $667.2 million after being reduced by outstanding letters of credit of $84.8 million. During the year ended December 31, 2016, we borrowed $907.0 million and repaid $967.0 million at a weighted average interest rate of 2.5%. There were no outstanding borrowings under the 2015 facility as of December 31, 2016. The 2015 facility matures on July 31, 2020. Borrowings under the 2015 facility bear interest, at our option, at either a eurodollar rate or a base rate, plus, in each case an applicable margin. The applicable margin ranges from 1.25% to 1.75% per annum in the case of eurodollar rate loans and 0.25% to 0.75% per annum in the case of base rate loans. The margin in either case is based on a measure of availability under the 2015 facility. A variable commitment fee, currently 0.375% per annum, is charged on the unused amount of the revolver based on quarterly average loan utilization. Letters of credit under the 2015 facility are assessed at a rate equal to the applicable eurodollar margin, currently 1.5%, as well as a fronting fee at a rate of 0.125% per annum. These fees are payable quarterly in arrears at the end of March, June, September, and December. All obligations under the 2015 term loan and 2015 facility will be guaranteed jointly and severally by the Company and all other subsidiaries that guarantee the 2024 notes. All obligations and the guarantees of those obligations will be secured by substantially all of the assets of the Company and the guarantors subject to certain exceptions and permitted liens, including (i) with respect to the 2015 term loan, a first-priority security interest in such assets that constitute Notes Collateral (as defined below) and a second priority security interest in such assets that constitute ABL Collateral (as defined below), and (ii) with respect to the 2015 facility, a first-priority security interest in such assets that constitute ABL Collateral and a second-priority security interest in such assets that constitute Notes Collateral. “ABL Collateral” includes substantially all presently owned and after-acquired accounts receivable, inventory, rights of unpaid vendors with respect to inventory, deposit accounts, commodity accounts, securities accounts and lock boxes, investment property, cash and cash equivalents, and general intangibles, books and records, supporting obligations and documents and related letters of credit, commercial tort claims or other claims related to and proceeds of each of the foregoing. “Notes Collateral” includes all collateral which is not ABL collateral. The 2015 term loan and the 2015 facility contain restrictive covenants which, among other things, limit the Company’s ability to incur additional indebtedness, incur liens, engage in mergers or other fundamental changes, sell certain assets, pay dividends, make acquisitions or investments, prepay certain indebtedness, change the nature of our business, and engage in certain transactions with affiliates. In addition, the 2015 facility also contains a financial covenant requiring the satisfaction of a minimum fixed charge ratio of 1.00 to 1.00 in the event that the Company does not meet a minimum measure of availability, currently the larger of $80.0 million or 10% of the maximum borrowing amount under the 2015 facility. Senior Secured Notes due 2024 As of December 31, 2016 we have $750.0 million outstanding in aggregate principal amount of the 2024 notes which mature on September 1, 2024. Interest accrues on the 2024 notes at a rate of 5.625% per annum and is payable semi-annually on March 1 and September 1 of each year, commencing on March 1, 2017. The terms of the 2024 notes are governed by the indenture, dated as of August 22, 2016 (the “Indenture”), among the Company, the guarantors named therein (the “Guarantors”) and Wilmington Trust, National Association, as trustee (the “Trustee”) and notes collateral agent (the “Notes Collateral Agent”). The 2024 notes, subject to certain exceptions, are guaranteed, jointly and severally, on a senior secured basis, by certain of our direct and indirect wholly owned subsidiaries. All obligations under the 2024 notes, and the guarantees of those obligations, are secured by substantially all of the assets of the Company and the Guarantors subject to certain exceptions and permitted liens, including a first-priority security interest in such assets that constitute Notes Collateral (as defined above) and a second-priority security interest in such assets that constitute ABL Collateral (as defined above). The Notes Collateral Agent became a party to the ABL/Bond Intercreditor Agreement, dated as of May 29, 2013, among SunTrust Bank, as agent under the Company’s 2015 facility, the Wilmington Trust, National Association, the Company and the Guarantors, and the Pari Passu Intercreditor Agreement, dated as of July 31, 2015, among Deutsche Bank AG New York Branch, as term collateral agent under the Company’s 2015 term loan, Wilmington Trust, National Association, the Company and the Guarantors. These documents govern all arrangements in respect of the priority of the security interests in the ABL Collateral and the Notes Collateral among the parties to the Indenture, the 2015 facility and the 2015 term loan. The 2024 notes constitute senior secured obligations of the Company and Guarantors, rank senior in right of payment to all future debt of the Company and Guarantors that is expressly subordinated in right of payment to the 2024 notes, and rank equally in right of payment with all existing and future liabilities of the Company and Guarantors that are not so subordinated, including the 2015 facility. The Indenture contains restrictive covenants that limit the ability of the Company and its restricted subsidiaries to, among other things, incur additional debt or issue preferred stock; create liens; create restrictions on the Company’s subsidiaries’ ability to make payments to the Company; pay dividends and make other distributions in respect of the Company’s and its subsidiaries’ capital stock; make certain investments or certain other restricted payments; guarantee indebtedness; designate unrestricted subsidiaries; sell certain kinds of assets; enter into certain types of transactions with affiliates; and effect mergers and consolidations. At any time prior to September 1, 2019, the Company may redeem the 2024 notes in whole or in part at a redemption price equal to 100% of the principal amount of the 2024 notes plus the “applicable premium” set forth in the Indenture. At any time on or after September 1, 2019, the Company may redeem the 2024 notes at the redemption prices set forth in the Indenture, plus accrued and unpaid interest, if any, to the redemption date. At any time and from time to time during the 36-month period following August 22, 2016 (“the Closing Date”), the Company may redeem up to 10% of the aggregate principal amount of the 2024 notes during each twelve-month period commencing on the Closing Date at a redemption price of 103% of the aggregate principal amount thereof plus accrued and unpaid interest to the redemption date. In addition, at any time prior to September 1, 2019, the Company may redeem up to 40% of the aggregate principal amount of the 2024 notes with the net cash proceeds of one or more equity offerings, as described in the Indenture, at a price equal to 105.625% of the principal amount thereof, plus accrued and unpaid interest, if any, to the redemption date. If the Company experiences certain change of control events, holders of the 2024 notes may require it to repurchase all or part of their 2024 notes at 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the repurchase date. As of December 31, 2016 we were not in violation of any covenants or restrictions imposed by any of our debt agreements. Future maturities of long-term debt as of December 31, 2016 were as follows (in thousands): Year ending December 31, 2017 $ 4,700 2018 4,700 2019 4,700 2020 4,700 2021 4,700 Thereafter 1,561,758 Total long-term debt (including current maturities) $ 1,585,258 Warrants Our previous term loan included detachable warrants that allowed for the purchase of up to 1.6 million shares of our common stock at a price of $2.50 per share. In April 2015, the remaining 0.7 million of outstanding, detachable warrants were exercised. The warrants were considered to be derivative financial instruments and were classified as liabilities. As such, they were measured at fair value on a recurring basis. Our share price and, to a lesser extent, the historical volatility of our common stock were the primary factors in the changes to our fair value measurements related to the warrants. All other inputs being equal, an increase or decrease in our share price or volatility resulted in an increase or decrease in the fair value of our warrants and an increase or decrease in interest expense. Non-cash fair value adjustments related to our derivative financial instrument recorded as interest expense in the consolidated statements of operations and comprehensive income (loss) for the years ended December 31 (in thousands) were as follows: Derivative Not Designated as Hedging Instruments Location of Gain (Loss) Recognized in Income Amount of Gain (Loss) 2016 2015 2014 Warrants Interest expense, net — (4,563) 456 We used the income approach to value our warrants by using the Black-Scholes option-pricing model. Using this model, the risk-free interest rate was based on the U.S. Treasury yield curve in effect on the valuation date. The expected life was based on the period of time until the expiration of the warrants. Expected volatility was based on the historical volatility of our common stock over the most recent period equal to the expected life of the warrants. The expected dividend yield was based on our history of not paying regular dividends in the past. These techniques incorporated Level 1 and Level 2 inputs. Significant inputs to the derivative valuation for the warrants were observable in the active markets and are classified as Level 2 in the hierarchy. Lease Finance Obligations As a result of the ProBuild acquisition, the Company is party to 150 individual property lease agreements with a single lessor as of December 31, 2016. These lease agreements have initial terms ranging from nine to fifteen years (expiring from 2016 through 2021) and renewal options in five-year increments providing for up to approximately 30-year remaining total lease terms. A related agreement between the lessor and the Company gives the Company the right to acquire a limited number of the leased facilities at fair market value. As a result of these purchase rights, the Company treats all of the properties that it leases from this lessor as a financing arrangement. The Company is also party to certain additional agreements with the same lessor which commit the Company to perform certain repair and maintenance obligations under the leases in a specified manner and timeframe. In 2006, we completed construction on a new multi-purpose facility. Based on the evaluation of the construction project in accordance with the Leases As of December 31, 2016, lease finance obligations consist of $238.5 million, with cash payments of $23.8 million for the year ended December 31, 2016. These lease finance obligations are included on the consolidated balance sheet as a component of long-term debt and lease obligations. The related assets are recorded as components of property, plant, and equipment on the consolidated balance sheet. Future minimum commitments for lease finance obligations as of December 31, 2016 were as follows (in thousands): Year ending December 31, 2017 $ 19,009 2018 18,974 2019 18,975 2020 18,893 2021 18,230 Thereafter 262,481 Total $ 356,562

The 2014 Plan also provides that all awards will become fully vested and/or exercisable upon a change in control (as defined in the 2014 Plan) if those awards (i) are not assumed or equitably substituted by the surviving entity or (ii) have been assumed or equitably substituted by the surviving entity, and the grantee’s employment is terminated under certain circumstances. Other specific terms for awards granted under the 2014 Plan shall be determined by our Compensation Committee (or the board of directors if so determined by the board of directors).

As of December 31, 2016, 6.0 million shares were available for issuance under the 2014 Plan. 2007 Incentive Plan Under our 2007 Incentive Plan (“2007 Plan”), the Company is authorized to grant awards in the form of incentive stock options, non-qualified stock options, restricted stock, other common stock-based awards and cash-based awards. In January 2010, our shareholders approved an amendment to our 2007 Plan which increased the number of shares of common stock that may be granted pursuant to awards under the 2007 Plan from 2.5 million shares to 7.0 million shares. The maximum number of common shares reserved for the grant of awards under the 2007 Plan is 7.0 million, subject to adjustment as provided by the 2007 Plan. No more than 7.0 million shares may be made subject to options or SARs granted under the 2007 Plan, and no more than 3.5 million shares may be made subject to stock-based awards other than options or SARs. Stock options and SARs granted under the 2007 Plan may not have a term exceeding 10 years from the date of grant.

The 1998 Plan also authorized the sale of common stock on terms determined by our board of directors. Stock options granted under the 1998 Plan generally cliff vest after a period of seven to nine years with certain option grants subject to acceleration if certain financial targets were met. The expiration date is generally 10 years subsequent to date of issuance. As of January 1, 2005, no further grants will be made under the 1998 Plan.

Facility Closure Costs	11. Facility Closure Costs When we close certain facilities, primarily related to location consolidation initiatives, we recognize expense related to the minimum future lease obligations over the remaining lease terms on closed facilities, net of estimated sub-rental income as well as employee severance costs. These expenses are recorded in selling, general, and administrative expense in the accompanying consolidated statement of operations and comprehensive income (loss). An analysis of our facility closure reserves for the periods reflected is as follows: 2014 Additions Assumed in Acquisition Payments 2015 Additions Payments 2016 (In thousands) Facility and other exit costs, net of estimated sub-lease rental income $ 1,147 $ 2,836 $ 12,494 $ (3,942 ) $ 12,535 $ 464 $ (4,776 ) $ 8,223 Employee severance and termination benefits — 1,434 — (1,181 ) 253 117 (358 ) 12 Total facility closure reserve $ 1,147 $ 4,270 $ 12,494 $ (5,123 ) $ 12,788 $ 581 $ (5,134 ) $ 8,235 The Company assumed $12.5 million of exit cost reserves as part of the ProBuild acquisition during 2015. The facility and other exit cost reserves of $8.2 million at December 31, 2016, of which $4.3 million is recorded as other long-term liabilities, are primarily related to future minimum lease payments on vacated facilities. As plans to close facilities are developed and executed, assets that can be used at other facilities are transferred and assets to be abandoned or sold are written down to their net realizable value, including any long-lived assets. In situations where multiple facilities serve the same market we may temporarily close, or idle, facilities with plans to reopen these facilities once demand returns to the market. In these situations, finite lived assets continue to be depreciated and assessed for impairment. Should conditions in our markets worsen, or recovery take significantly longer than forecasted, we may temporarily idle or permanently close additional facilities, at which time we may incur additional facility closure costs or asset impairment charges. Future non-cash impairment charges would have the effect of decreasing our earnings or increasing our losses in such period, but would not impact our current outstanding debt obligations or compliance with covenants contained in the related debt agreements. We continuously monitor economic conditions in all of our markets and changes in market conditions may warrant future closings or idling of facilities. In addition, as we continue the integration of ProBuild we may close or idle other facilities.

In general terms, an ownership change may result from transactions that increase the aggregate ownership of certain stockholders in the Company’s stock by more than 50 percentage points over a three year testing period (“Section 382 Ownership Change”). If the Company were to experience a Section 382 Ownership Change, an annual limitation would be imposed on certain of the Company’s tax attributes, including NOL and capital loss carryforwards, and certain other losses, credits, deductions or tax basis. At December 31, 2016 and 2015, the Company had deferred tax assets, net of deferred tax liabilities, of $120.1 million and $127.1 million, respectively, offset by valuation allowances of $4.8 million and $136.5 million, respectively. We have $411.4 million of state net operating loss carry-forwards, which includes $2.5 million of state tax credit carry-forwards expiring at various dates through 2036. We also have $226.5 million of federal net operating loss carry-forwards that will expire at various dates through 2036. The federal and state net operating loss carry-forwards include approximately $23.3 million of gross windfall tax benefits from stock option exercises that have not been recorded as of December 31, 2016. At December 31, 2016, the Company needed to generate approximately $287.6 million of pre-tax income in future periods to realize its federal deferred tax assets. We evaluate our deferred tax assets on a quarterly basis to determine whether a valuation allowance is required. In accordance with the Income Taxes We recorded a full valuation allowance in 2008 due to our cumulative three-year loss position at that time, compounded by the negative industry-wide business trends and outlook. At December 31, 2015, the Company had given significant weight to the negative objective evidence of the historically weak housing market conditions during the housing downturn that contributed to our three-year cumulative pre-tax loss position when reporting a valuation allowance of $136.5 million against our deferred income tax assets, representing a valuation allowance against substantially all of our net deferred income tax assets. In the second quarter of 2016, we moved from a cumulative loss position over the previous three years to a cumulative income position for the first time since we established the full valuation allowance in 2008. We continued to maintain a cumulative income position over the previous three years into the third quarter of 2016. In the Company’s evaluation at September 30, 2016, we gave the most significant weight to this objective positive evidence related to its recent financial results. Additionally, even conservative projections of the Company’s estimated future annual pre-tax income would indicate realization of all of its federal net operating losses well in advance of the expiration of the Company’s NOL carryforwards and it would also absorb all federal deductible temporary differences as they reverse in future years. The Company considered, at a lower weighting, the subjective positive evidence that it expects to increase its pre-tax income in future years as the homebuilding industry continues to recover and strengthen as currently projected by a composite of third-party sources, including the NAHB. Therefore, at September 30, 2016, with this positive historical evidence and the projection of future profitability, management determined that there was sufficient positive evidence to conclude that it is more likely than not that we would realize our net federal and certain state deferred tax assets, resulting in a $117.6 million and $3.2 million benefit being recognized in our provision for income taxes for the third and fourth quarter of 2016, respectively. Prior to the quarter ended June 30, 2016, the Company had given significant weight to the negative objective evidence of its three-year cumulative pre-tax loss position as a result of losses incurred in prior years during the housing downturn. As of June 30, 2016 and September 30, 2016, the Company had generated positive cumulative pre-tax income for the past three years and therefore, the prior year losses were weighted less than the recent positive financial results in the Company’s evaluation at September 30, 2016. Other negative subjective evidence, such as the cyclical, slower-than-anticipated housing market recovery, was considered at a lower weighting because the Company’s recent financial performance has been achieved in this environment. As of December 31, 2016, we have certain states where we are not currently projecting future taxable income levels that would be sufficient to utilize the carryover net operating losses and as such continue to maintain a valuation allowance against certain of these state deferred tax assets. We will continue to assess quarterly whether it is more likely than not that some or all of these state deferred tax assets will be realizable in the future. Changes in the positive and negative evidence, including differences in the Company’s future operating results as compared to the estimates utilized in the determination of the valuation allowance, could result in changes in the Company’s estimate of the valuation allowance related to its tax benefits for state net operating loss carryforwards. In 2016 we recorded a reduction to the valuation allowance of $131.7 million against our net deferred tax assets as we released valuation allowances on our net deferred tax assets as noted above. In 2015, we recorded a valuation allowance of $9.7 million related to our continuing operations. In 2014, we reduced our valuation allowance by $7.2 million due to the utilization of net operating losses against federal and state taxable income. We base our estimate of deferred tax assets and liabilities on current tax laws and rates. In certain cases, we also base our estimate on business plan forecasts and other expectations about future outcomes. Changes in existing tax laws or rates could affect our actual tax results, and future business results may affect the amount of our deferred tax liabilities or the valuation of our deferred tax assets over time. Due to uncertainties in the estimation process, particularly with respect to changes in facts and circumstances in future reporting periods, as well as the residential homebuilding industry’s cyclicality and sensitivity to changes in economic conditions, it is possible that actual results could differ from the estimates used in previous analyses. Accounting for deferred taxes is based upon estimates of future results. Differences between the anticipated and actual outcomes of these future results could have a material impact on our consolidated results of operations or financial position. The following table shows the changes in our valuation allowance: 2016 2015 2014 (In thousands) Balance at January 1, $ 136,548 $ 133,183 $ 143,682 Additions charged to expense: Continuing operations — 9,679 — Discontinued operations — — 131 Reductions credited to expense: Continuing operations (131,727 ) — (7,178 ) Discontinued operations — (55 ) — Deductions — (6,259 ) (3,452 ) Balance at December 31, $ 4,821 $ 136,548 $ 133,183 We accrue interest and penalties on our uncertain tax positions as a component of our provision for income taxes. We accrued no significant interest and penalties in 2016, 2015 or 2014. We had a total of $0.3 million and $0.3 million accrued for interest and penalties for our uncertain tax positions as of December 31, 2016 and 2015, respectively. The following table shows the changes in the amount of our uncertain tax positions (exclusive of the effect of interest and penalties): 2016 2015 2014 (In thousands) Balance at January 1, $ 208 $ 378 $ 950 Tax positions taken in prior periods: Gross increases 18 — 2 Gross decreases — — — Tax positions taken in current period: Gross increases 23 12 13 Settlements with taxing authorities — — — Lapse of applicable statute of limitations (0 ) (182 ) (587 ) Balance at December 31, $ 249 $ 208 $ 378 The balance for uncertain tax positions was $0.2 million as of December 31, 2016 excluding penalties and interest. We are subject to U.S. federal income tax as well as income tax of multiple state jurisdictions. Based on completed examinations and the expiration of statutes of limitations, we have concluded all U.S. federal income tax matters for years through 2012. We report in 41 states with various years open to examination.

Compensation And Retirement Disclosure [Abstract]
Employee Benefit Plans	13. Employee Benefit Plans As a result of the ProBuild acquisition we maintain two active defined contribution 401(k) plans. Our employees are eligible to participate in the plans subject to certain employment eligibility provisions. Participants can contribute up to 15% of their annual compensation, subject to federally mandated maximums. Participants are immediately vested in their own contributions. We match a certain percentage of the contributions made by participating employees, subject to IRS limitations. Our matching contributions are subject to a pro-rata five-year vesting schedule. We recognized expense of $4.6 million, $6.5 million and $0.4 million in 2016, 2015 and 2014, respectively, for contributions to the plan. Through the ProBuild acquisition, the Company acquired a defined benefit plan, the ProBuild Retirement Plan, which was terminated as of January 30, 2015. The Company has made all remaining plan benefit distributions and the plan was fully terminated and settled as of December 31, 2015. The Company contributes to multiple collectively bargained union retirement plans including multiemployer plans. The Company does not administer the multiemployer plans, and contributions are determined in accordance with the provisions of negotiated labor contracts. The risks of participating in multiemployer plans are different from single-employer plans. Assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers. If a participating employer stops contributing to a multiemployer plan, the unfunded obligations of that multiemployer plan may be borne by the remaining participating employers. If the Company chooses to stop participating in a multiemployer plan, the Company may be required to pay that plan an amount (“withdrawal liability”) based on the plan’s formula and the underfunded status of the plan attributable to the Company. Contributions to the plans for the years ended December 31, 2016 and 2015 were not significant.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	14. Commitments and Contingencies We lease certain land, buildings and equipment used in operations. These leases are generally accounted for as operating leases with initial terms ranging from one to 20 years and they generally contain renewal options. Certain operating leases are subject to contingent rentals based on various measures, primarily consumer price index increases. We also lease certain properties from related parties, including current employees and non-affiliate stockholders. Total rent expense under operating leases was approximately $68.7 million, $43.6 million and $25.4 million for the years ended December 31, 2016, 2015, and 2014, respectively. In addition, we have residual value guarantees on certain equipment leases. Under these leases we have the option of (a) purchasing the equipment at the end of the lease term, (b) arranging for the sale of the equipment to a third party, or (c) returning the equipment to the lessor to sell the equipment. If the sales proceeds in any case are less than the residual value, we are required to reimburse the lessor for the deficiency up to a specified level as stated in each lease agreement. If the sales proceeds exceed the residual value, we are entitled to all of such excess amounts. The guarantees under these leases for the residual values of equipment at the end of the respective operating lease periods approximated $3.9 million as of December 31, 2016. Based upon the expectation that none of these leased assets will have a residual value at the end of the lease term that is materially less than the value specified in the related operating lease agreement or that we will purchase the equipment at the end of the lease term, we do not believe it is probable that we will be required to fund any amounts under the terms of these guarantee arrangements. Accordingly, no accruals have been recognized for these guarantees. Future minimum commitments for noncancelable operating leases with initial or remaining lease terms in excess of one year are as follows: Related Party Total* (In thousands) Year ending December 31, 2017 $ 1,010 $ 67,213 2018 336 57,619 2019 350 46,536 2020 360 33,056 2021 375 22,915 Thereafter 1,019 56,192 $ 3,450 $ 283,531 * Includes related party future minimum commitments for noncancelable operating leases. As of December 31, 2016, we had outstanding letters of credit totaling $84.8 million under our 2015 facility that principally support our self-insurance programs. Beginning in the fourth quarter, the Company has seen an increased occurrence of known and threatened construction defect legal claims primarily in two states. While these claims are generally covered under the Company’s existing insurance programs to the extent any loss exceeds the deductible, there is a reasonable possibility of loss that is not able to be estimated at this time because (i) many of the proceedings are in the discovery stage, (ii) the outcome of future litigation is uncertain, and/or (iii) the complex nature of the claims. Although the Company cannot estimate a reasonable range of loss based on currently available information, the resolution of these matters could have an adverse effect on the Company's financial position, results of operations or cash flows. We are a party to various legal proceedings in the ordinary course of business. Although the ultimate disposition of these proceedings cannot be predicted with certainty, management believes the outcome of any claim that is pending or threatened, either individually or on a combined basis, will not have a material adverse effect on our consolidated financial position, cash flows or results of operations. However, there can be no assurances that future adverse judgments and costs would not be material to our results of operations or liquidity for a particular period.

Segment Reporting [Abstract]
Segment and Product Information	15. Segment and Product Information We offer an integrated solution to our customers providing manufacturing, supply, and installation of a full range of structural and related building products. We provide a wide variety of building products and services directly to homebuilder customers. We manufacture floor trusses, roof trusses, wall panels, stairs, millwork, windows, and doors. We also provide a full range of construction services. These product and service offerings are distributed across 400 locations operating in 40 states across the United States, which have been reorganized into nine geographical regions following the ProBuild acquisition. Centralized financial and operational oversight, including resource allocation and assessment of performance on an income (loss) from continuing operations before income taxes basis, is performed by our CEO, whom we have determined to be our chief operating decision maker (“CODM”). As a result of the reorganization following the ProBuild acquisition, the Company has nine operating segments aligned with its nine geographical regions (Regions 1 through 9). While all of our operating segments have similar nature of products, distribution methods and customers, certain of our operating segments have been aggregated due to also containing similar economic characteristics, resulting in the following composition of reportable segments: • Regions 1 and 2 have been aggregated to form the “Northeast” reportable segment • Regions 3 and 5 have been aggregated to form the “Southeast” reportable segment • Regions 4 and 6 have been aggregated to form the “South” reportable segment • Region 7, 8 and 9 have been aggregated to form the “West” reportable segment In addition to our reportable segments, our consolidated results include corporate overhead, other various operating activities that are not internally allocated to a geographical region nor separately reported to the CODM, and certain reconciling items primarily related to allocations of corporate overhead and rent expense, which have collectively been presented as “All Other”. The accounting policies of the segments are consistent with those described in Note 2, except for noted reconciling items. The following tables present Net sales, Income (loss) before income taxes and certain other measures for the reportable segments, reconciled to consolidated total operations, for the years ended December 31, (in thousands): 2016 Reportable segments Net Sales Depreciation & Amortization Interest Income (loss) before income taxes Northeast $ 1,204,099 $ 18,220 $ 18,660 $ 35,356 Southeast 1,367,933 11,384 19,956 37,158 South 1,704,753 22,139 22,331 69,846 West 1,939,206 33,775 27,143 72,649 Total reportable segments 6,215,991 85,518 88,090 215,009 All other 151,293 24,275 126,577 (193,340 ) Total consolidated $ 6,367,284 $ 109,793 $ 214,667 $ 21,669 2015 Reportable segments Net Sales Depreciation & Amortization Interest Income (loss) before income taxes Northeast $ 626,985 $ 4,201 $ 7,508 $ 28,862 Southeast 917,022 5,296 14,598 14,607 South 1,073,240 10,649 12,707 50,878 West 786,476 5,824 6,118 35,170 Total reportable segments 3,403,723 25,970 40,931 129,517 All other 160,702 32,310 68,268 (147,961 ) Total consolidated $ 3,564,425 $ 58,280 $ 109,199 $ (18,444) 2014 Reportable segments Net Sales Depreciation & Amortization Interest Income (loss) before income taxes Northeast $ 229,998 $ 1,068 $ 3,634 $ 3,464 Southeast 672,059 2,743 11,925 5,465 South 558,446 2,621 7,666 17,804 West — — — — Total reportable segments 1,460,503 6,432 23,225 26,733 All other 143,593 3,087 7,124 (7,472 ) Total consolidated $ 1,604,096 $ 9,519 $ 30,349 $ 19,261 Asset information by segment is not reported internally or otherwise reviewed by the CODM nor does the company earn revenues or have long-lived assets located in foreign countries.

Sherman, our chief executive officer, and Brett Milgrim, a member of the Company’s board of directors, serve on the board of directors for PGT, Inc.. We purchased windows from PGT, Inc. totaling $11.4 million, $9.3 million and $6.3 million in 2016, 2015 and 2014, respectively. We had accounts payable to PGT, Inc. in the amounts of $1.4 million and $1.1 million as of December 31, 2016 and 2015, respectively. In 2016, 2015 and 2014, we paid approximately $0.7 million, $1.0 million and $0.9 million, respectively, in rental expense to employees or our non-affiliate stockholders for leases of land and buildings. Transactions between the Company and other related parties occur in the ordinary course of business. However, the Company carefully monitors and assesses related party relationships. Management does not believe that any of these transactions with related parties had a material impact on the Company’s results for the years ended December 31, 2016, 2015 or 2014.

Subsequent Events [Abstract]
Subsequent Event	18. Subsequent Event On February 23, 2017, we repriced our existing 2015 term loan through an amendment and extension of the term loan credit agreement providing for a $467.7 million senior secured term loan facility due 2024 (“2024 term loan”). This repricing reduces the interest rate by 0.75% and extends the maturity by 19 months to February 29, 2024. The 2024 term loan bears interest based on either a eurodollar or base rate (a rate equal to the highest of an agreed commercially available benchmark rate, the federal funds effective rate plus 0.50% or the eurodollar rate plus 1.0%, as selected by the Company) plus, in each case, an applicable margin. The applicable margin in the 2024 term loan is (x) 3% in the case of Eurodollar rate loans and (y) 2% in the case of base rate loans. These rates represents a 0.75% reduction from the 2015 term loan. Deutsche Bank AG New York Branch continues to serve as administrative agent and collateral agent under the 2024 term loan.

Principles of Consolidation	Principles of Consolidation The consolidated financial statements present the results of operations, financial position, and cash flows of Builders FirstSource, Inc. and its wholly-owned subsidiaries. All intercompany transactions have been eliminated in consolidation.
Accounting Estimates	Accounting Estimates The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates. Estimates are used when accounting for items such as revenue, vendor rebates, allowance for returns, discounts and doubtful accounts, employee compensation programs, depreciation and amortization periods, income taxes, inventory values, insurance programs, goodwill, other intangible assets and long-lived assets.
Sales Recognition	Sales Recognition We recognize sales of building products upon delivery to the customer. For contracts with service elements, sales are generally recognized on the completed contract method as these contracts are usually completed within 30 days with the percentage of completion method applied on a limited basis to certain contracts. Percentage of completion revenue represents less than 2% of our consolidated sales for each year presented. Contract costs include all direct material and labor, equipment costs and those indirect costs related to contract performance. Provisions for estimated losses on uncompleted contracts are recognized in the period in which such losses are determined. Prepayments for materials or services are deferred until such materials have been delivered or services have been provided. All sales recognized are net of allowances for discounts and estimated returns, based on historical experience. We present all sales tax on a net basis in our consolidated financial statements. The Company records sales incentives provided to customers as a reduction of revenue.
Cash and Cash Equivalents & Check Outstanding	Cash and Cash Equivalents & Checks Outstanding Cash and cash equivalents consist of cash on hand and all highly liquid investments with an original maturity date of three months or less. Also included in cash and cash equivalents are proceeds due from credit card transactions that generally settle within two business days. We maintain cash at financial institutions in excess of federally insured limits. Further, we maintain various banking relationships with different financial institutions. Accordingly, when there is a negative book cash balance resulting from outstanding checks that had not yet been paid by any single financial institution; they are reflected in checks outstanding on the accompanying consolidated balance sheets.
Financial Instruments	Financial Instruments We use financial instruments in the normal course of business as a tool to manage our assets and liabilities. We do not hold or issue financial instruments for trading purposes. We issued detachable warrants in 2011, which were measured at fair value on a recurring basis until exercised in 2015 as discussed in Note 8.
Accounts Receivable	Accounts Receivable We extend credit to qualified professional homebuilders and contractors, in many cases on a non-collateralized basis. Accounts receivable potentially expose us to concentrations of credit risk. Because our customers are dispersed among our various markets, our credit risk to any one customer or state economy is not significant. Our customer mix is a balance of large national homebuilders, regional homebuilders, local homebuilders and repair and remodeling contractors. For the year ended December 31, 2016, our top 10 customers accounted for approximately 16.8% of our sales, and no single customer accounted for more than 5% of sales. The allowance for doubtful accounts is based on management’s assessment of the amount which may become uncollectible in the future and is estimated using specific review of problem accounts, overall portfolio quality, current economic conditions that may affect the borrower’s ability to pay, and historical experience. Accounts receivable are written off when deemed uncollectible. Other receivables consist primarily of vendor rebates receivable. We also establish reserves for credit memos and customer returns. The reserve balance was $5.6 million and $3.8 million at December 31, 2016 and 2015, respectively. The activity in this reserve was not significant for each year presented. Accounts receivable consisted of the following at December 31: 2016 2015 (In thousands) Accounts Receivable $ 580,779 $ 536,593 Less: allowances for returns and doubtful accounts 11,571 8,049 Accounts receivable, net $ 569,208 $ 528,544 The following table shows the changes in our allowance for doubtful accounts: 2016 2015 2014 (In thousands) Balance at January 1, $ 4,245 $ 1,734 $ 2,413 Additions 1,390 2,285 (274 ) Deductions (write-offs, net of recoveries) 287 226 (405 ) Balance at December 31, $ 5,922 $ 4,245 $ 1,734
Inventories	Inventories Inventories consist principally of materials purchased for resale, including lumber, sheet goods, windows, doors and millwork, as well as certain manufactured products and are stated at the lower of cost or market. Cost is determined using the weighted average method, the use of which approximates the first-in, first-out method. We accrue for shrink based on the actual historical shrink results of our most recent physical inventories adjusted, if necessary, for current economic conditions. These estimates are compared with actual results as physical inventory counts are taken and reconciled to the general ledger. During the year, we monitor our inventory levels by market and record provisions for excess inventories based on slower moving inventory. We define potential excess inventory as the amount of inventory on hand in excess of the historical usage, excluding special order items purchased in the last six months. We then apply our judgment as to forecasted demand and other factors, including liquidation value, to determine the required adjustments to net realizable value. Our inventories are generally not susceptible to technological obsolescence. Our arrangements with vendors provide for rebates of a specified amount of consideration, payable when certain measures, generally related to a stipulated level of purchases, have been achieved. We account for estimated rebates as a reduction of the prices of the vendor’s inventory until the product is sold, at which time such rebates reduce cost of sales in the accompanying consolidated statements of operations and comprehensive loss. Throughout the year we estimate the amount of the rebates based upon the expected level of purchases. We continually revise these estimates based on actual purchase levels. We source products from a large number of suppliers. No materials purchased from any single supplier represented more than 7% of our total materials purchased in 2016.
Shipping and Handling Costs	Shipping and Handling Costs Handling costs incurred in manufacturing activities are included in cost of sales. All other shipping and handling costs are included in selling, general and administrative expenses in the accompanying consolidated statements of operations and comprehensive income (loss) and totaled $269.8 million, $171.9 million and $79.7 million in 2016, 2015 and 2014, respectively.
Income Taxes	Income Taxes We account for income taxes utilizing the liability method described in the Income Taxes
Warranty Expense	Warranty Expense We have warranty obligations with respect to most manufactured products; however, the liability for the warranty obligations is not significant as a result of third-party inspection and acceptance processes.
Debt Issuance Costs and Debt Discount	Debt Issuance Costs and Debt Discount Loan costs are capitalized upon the issuance of long-term debt and amortized over the life of the related debt. Debt issuance costs associated with term debt are presented as a reduction to long-term debt. Debt issuance costs associated with revolving debt arrangements are presented as a component of other assets. Debt issuance costs incurred in connection with revolving debt arrangements are amortized using the straight-line method. Debt issuance costs incurred in connection with term debt are amortized using the effective interest method. Debt discount is amortized over the life of the related debt using the effective interest method. Amortization of debt issuance costs and the debt discount are included in interest expense. Upon changes to our debt structure, we evaluate debt issuance costs in accordance with the Debt
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are recorded at cost and depreciated using the straight-line method over the estimated useful lives of the assets. The estimated lives of the various classes of assets are as follows: Buildings and improvements 20 to 40 years Machinery and equipment 3 to 10 years Furniture and fixtures 3 to 5 years Leasehold improvements The shorter of the estimated useful life or the remaining lease term Major additions and improvements are capitalized, while maintenance and repairs that do not extend the useful life of the property are charged to expense as incurred. Gains or losses from dispositions of property, plant and equipment are recorded in the period incurred. We also capitalize certain costs of computer software developed or obtained for internal use, including interest, provided that those costs are not research and development, and certain other criteria are met. Internal use computer software costs are included in machinery and equipment and generally depreciated using the straight-line method over the estimated useful lives of the assets, generally three years. We periodically evaluate the commercial and strategic operation of the land, related buildings and improvements of our facilities. In connection with these evaluations, some facilities may be consolidated, and others may be sold or leased. Nonoperating assets primarily related to land and building real estate assets associated with location closures that are actively being marketed for sale within a year are classified as assets held for sale and recorded at fair value, usually the quoted market price obtained from an independent third-party less the cost to sell. Until the assets are sold, an estimate of the fair value is reassessed at each reporting period. Net gains or losses related to the sale of real estate and equipment or impairment adjustments related to assets held for sale are recorded as selling, general and administrative expenses.
Long-Lived Assets	Long-Lived Assets We evaluate our long-lived assets, other than goodwill, for impairment when events or changes in circumstances indicate, in our judgment, that the carrying value of such assets may not be recoverable. The determination of whether or not impairment exists is based on our estimate of undiscounted future cash flows before interest attributable to the assets as compared to the net carrying value of the assets. If impairment is indicated, the amount of the impairment recognized is determined by estimating the fair value of the assets based on estimated discounted future cash flows and recording a provision for loss if the carrying value is greater than estimated fair value. The net carrying value of assets identified to be disposed of in the future is compared to their estimated fair value, usually the quoted market price obtained from an independent third-party less the cost to sell, to determine if impairment exists. Until the assets are disposed of, an estimate of the fair value is reassessed when related events or circumstances change. Asset impairment charges are presented in the consolidated statements of operations and comprehensive income (loss) for the respective years.
Insurance	Insurance We have established insurance programs to cover certain insurable risks consisting primarily of physical loss to property, business interruptions resulting from such loss, workers’ compensation, employee healthcare, and comprehensive general and auto liability. Third party insurance coverage is obtained for exposures above predetermined deductibles as well as for those risks required to be insured by law or contract. Provisions for losses are developed from valuations that rely upon our past claims experience, which considers both the frequency and settlement of claims. We discount our workers’ compensation liability based upon estimated future payment streams at our risk-free rate. Our total insurance reserve balances were $80.4 million and $84.3 million as of December 31, 2016 and 2015, respectively. Of these balances $43.6 million and $40.3 million were recorded as other long-term liabilities as of December 31, 2016 and 2015, respectively. Included in these reserve balances as of December 31, 2016 and 2015, were approximately $9.4 million and $9.9 million, respectively, of claims that exceeded stop-loss limits and are expected to be recovered under insurance policies which are also recorded as other receivables and other assets in the accompanying consolidated balance sheets.
Net Income (Loss) per Common Share	Net Income (Loss) per Common Share Net income (loss) per common share, or earnings per share (“EPS”), is calculated in accordance with the Earnings per Share The table below presents a reconciliation of weighted average common shares used in the calculation of basic and diluted EPS for the years ended December 31: 2016 2015 2014 (In thousands) Weighted average shares for basic EPS 110,754 103,190 98,050 Dilutive effect of options, warrants, and RSUs 2,831 — 2,472 Weighted average shares for diluted EPS 113,585 103,190 100,522 Our restricted stock shares include rights to receive dividends that are not subject to the risk of forfeiture even if the underlying restricted stock shares on which the dividends were paid do not vest. In accordance with the Earnings Per Share For the purpose of computing diluted EPS, weighted average shares outstanding have been adjusted for common shares underlying 3,515,000 options to purchase common stock and 2,177,000 restricted stock units (“RSUs”) for 2016. Options to purchase 4,998,000 shares of common stock and 1,516,000 RSUs were not included in the computation of diluted EPS for 2015 because their effect was anti-dilutive. Incremental shares attributable to average warrants outstanding during 2015 were not included in the computation of diluted EPS for 2015 as their effect was anti-dilutive. There were no warrants outstanding at December 31, 2016 as all of the remaining warrants were exercised in April 2015. Weighted average shares outstanding have been adjusted for common shares underlying 6,246,000 options, 700,000 warrants, and 1,855,000 RSUs for 2014. In addition, $0.5 million of income due to fair value adjustments related to the warrants was excluded from net income in the computation of diluted EPS for 2014.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Intangibles subject to amortization We recognize an acquired intangible asset apart from goodwill whenever the intangible asset arises from contractual or other legal rights, or whenever it can be separated or divided from the acquired entity and sold, transferred, licensed, rented, or exchanged, either individually or in combination with a related contract, asset or liability. Impairment losses are recognized if the carrying value of an intangible asset subject to amortization is not recoverable from expected future cash flows and its carrying amount exceeds its estimated fair value. Goodwill We recognize goodwill as the excess cost of an acquired entity over the net amount assigned to assets acquired and liabilities assumed. Goodwill is tested for impairment on an annual basis and between annual tests whenever impairment is indicated. This annual test takes place as of December 31 each year. Impairment losses are recognized whenever the implied fair value of goodwill is less than its carrying value.
Stock-based Compensation	Stock-based Compensation We have four stock-based employee compensation plans, which are described more fully in Note 10. We issue new common stock shares upon exercises of stock options, grants of restricted stock, and vesting of RSUs. The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions for the year ended December 31: 2016 2015 2014 Expected life 6.0 years 6.0 years 5.8 years Expected volatility 60.88% 75.2% 92.1% Expected dividend yield 0.00% 0.00% 0.00% Risk-free rate 1.41% 1.75% 1.83% The expected life represents the period of time the options are expected to be outstanding. We used the simplified method for determining the expected life assumption due to limited historical exercise experience on our stock options. The expected volatility is based on the historical volatility of our common stock over the most recent period equal to the expected life of the option. The expected dividend yield is based on our history of not paying regular dividends in the past and our current intention to not pay regular dividends in the foreseeable future. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant and has a term equal to the expected life of the options. The fair value of RSU awards subject to market conditions is estimated on the date of grant using the Monte Carlo simulation model with the following weighted average assumptions for the year ended December 31: 2016 Expected volatility (company) 53.6% Expected volatility (peer group median) 17.3% Correlation between the company and peer group median 0.47 Expected dividend yield 0.00% Risk-free rate 1.29% The expected volatilities are based on the historical volatilities of our common stock and the common stocks of the constituents of the Company’s peer group over the most recent period equal to the measurement period. The expected dividend yield is based on our history of not paying regular dividends in the past and our current intention to not pay regular dividends in the foreseeable future. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant and has a term equal to the measurement period. We did not grant any RSUs subject to market conditions in 2015 or 2014.
Fair Value	Fair Value The Fair Value Measurements and Disclosures Level 1 — unadjusted quoted prices for identical assets or liabilities in active markets accessible by us Level 2 — inputs that are observable in the marketplace other than those inputs classified as Level 1 Level 3 — inputs that are unobservable in the marketplace and significant to the valuation If a financial instrument uses inputs that fall in different levels of the hierarchy, the instrument will be categorized based upon the lowest level of input that is significant to the fair value calculation. The only financial instruments measured at fair value on a recurring basis were our warrants as discussed in Note 8. As of December 31, 2016 and 2015 the Company does not have any financial instruments which are measured at fair value on a recurring basis. We have elected to report the value of our 10.75% senior unsecured notes due 2023 (“2023 notes”), 5.625% senior secured notes due 2024 (“2024 notes”), and $600.0 million term loan facility due 2022 (“2015 term loan”) at amortized cost. The fair values of the 2023 notes, the 2024 notes and the 2015 term loan at December 31, 2016 were approximately $421.8 million, $758.0 million and $471.2 million, respectively, and were determined using Level 2 inputs based on market prices.
Supplemental Cash Flow Information	Supplemental Cash Flow Information Supplemental cash flow information was as follows for the years ended December 31: 2016 2015 2014 (In thousands) Cash payments for interest $ 197,384 $ 55,028 $ 28,338 Cash payments for income taxes 2,875 1,409 456
Comprehensive Income (Loss)	Comprehensive Income (Loss) Comprehensive income (loss) is defined as the change in equity (net assets) of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. It consists of net income (loss) and other gains and losses affecting stockholders’ equity that, under GAAP, are excluded from net income. We had no items of other comprehensive income (loss) for the years ended December 31, 2016, 2015, and 2014.
