NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of Ply Gem Holdings, Inc. and its subsidiaries (referred to herein as “Ply Gem Holdings”, “Ply Gem”, the “Company”, “we”, “us”, or “our”) have been prepared in accordance with U.S. generally accepted accounting principles as described in the consolidated financial statements and related notes included in our 2015 Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 14, 2016.  These statements do not include all of the information and footnotes required by U.S. generally accepted accounting principles and should be read in conjunction with our 2015 Annual Report on Form 10-K.  In management’s opinion, all normal and recurring adjustments considered necessary for a fair presentation have been included.  Operating results for the period from January 1, 2016 through October 1, 2016 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016.

The condensed consolidated balance sheet at December 31, 2015 has been derived from the audited consolidated financial statements of Ply Gem Holdings at that date, but does not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements.

The Company’s fiscal quarters are based on periods ending on the Saturday of the last week in the quarter.  Therefore, the financial results of certain fiscal quarters will not be comparable to the prior and subsequent fiscal quarters.  The accompanying financial statements include the Company’s condensed consolidated statements of operations and comprehensive income (loss) for the three and nine months ended October 1, 2016 and October 3, 2015, the condensed consolidated statements of cash flows for the nine months endedOctober 1, 2016 and October 3, 2015, and the condensed consolidated balance sheets as of October 1, 2016 and December 31, 2015.

Ply Gem is a diversified manufacturer of residential and commercial building products, which are sold primarily in the United States and Canada, and include a wide variety of products for the residential and commercial construction, the do-it-yourself and the professional remodeling and renovation markets.  The demand for the Company’s products is seasonal, particularly in the Northeast and Midwest regions of the United States and Canada where inclement weather during the winter months usually reduces the level of building and remodeling activity in both the home repair and remodeling and new home construction sectors.  The Company’s sales are usually lower during the first and fourth quarters.

To a significant extent our performance is dependent upon the levels of home repair and remodeling and new home construction spending, all of which are affected by such factors as interest rates, inflation, consumer confidence, unemployment, and availability of consumer credit.

Principles of Consolidation

The condensed consolidated financial statements include the accounts of Ply Gem Holdings and its subsidiaries, all of which are wholly owned.  All intercompany accounts and transactions have been eliminated.

Reclassifications

Due to the adoption of ASU No. 2015-03, Interest-Imputation of Interest, certain balance sheet amounts in the prior fiscal year have been reclassified to conform to the presentation adopted in the current fiscal year, with no effect on net income, accumulated deficit, or net cash provided by (used in) operating, investing, and financing activities. Refer to Note 5, Long-Term Debt, for the presentation impact on net debt.

Accounting Policies and Use of Estimates

The preparation of these condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles involves estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of income and expense during the reporting periods.  Certain of the Company’s accounting policies require the application of judgment in selecting the appropriate assumptions for calculating financial estimates.  By their nature, these judgments are subject to an inherent degree of uncertainty.  The Company periodically evaluates the judgments and estimates used in their critical accounting policies to ensure that such judgments and estimates are reasonable.  Such estimates include the allowance for doubtful accounts receivable, rebates, pensions, valuation of inventories, warranty reserves, insurance reserves, legal contingencies, assumptions used in the calculation of income taxes and the tax receivable agreement liability, projected cash flows used in the goodwill and intangible asset impairment tests, and environmental accruals and other contingencies.  These judgments are based on the Company’s historical experience, current trends and information available from other sources, and are based on management’s best estimates and judgments.  The Company adjusts such estimates and assumptions when facts and circumstances dictate.  Volatile equity markets, foreign currency, and litigation risk have combined to increase the uncertainty inherent in such estimates and assumptions.  If different conditions result from those assumptions used in the Company’s judgments, actual results could be materially different from the Company’s estimates.

Cash and Cash Equivalents

Cash equivalents consist of short-term highly liquid investments with original maturities of three months or less and which are readily convertible into cash.

Accounts Receivable

Accounts receivable-trade are recorded at their net realizable value.  The allowance for doubtful accounts was $3.0 million at October 1, 2016 and $3.6 million at December 31, 2015.  The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The Company estimates the allowance for doubtful accounts based on a variety of factors including the length of time receivables are past due, the financial health of its customers, unusual macroeconomic conditions and historical experience. If the financial condition of its customers deteriorates or other circumstances occur that result in an impairment of customers’ ability to make payments, the Company records additional allowances as needed. The Company writes off uncollectible trade accounts receivable against the allowance for doubtful accounts when collection efforts have been exhausted and/or any legal action taken by the Company has concluded.

Inventories

Inventories in the accompanying condensed consolidated balance sheets are valued at the lower of cost or net realizable value and are determined primarily by the first-in, first-out (FIFO) method.  The Company records provisions, as appropriate, to write-down obsolete and excess inventory to estimated net realizable value.  The process for evaluating obsolete and excess inventory often requires the Company to make subjective judgments and estimates concerning future sales levels, quantities and prices at which such inventory will be able to be sold in the normal course of business.  Accelerating the disposal process or incorrect estimates of future sales potential may cause actual results to differ from the estimates at the time such inventory is disposed or sold. As of October 1, 2016, the Company has no inventory purchase commitments.

Inventory provisions were approximately $9.6 million at October 1, 2016, increasing during the nine months endedOctober 1, 2016 by $1.3 million compared to the December 31, 2015 provision balance of approximately $8.3 million.

Property and Equipment

Property and equipment are presented at cost.  Depreciation of property and equipment are provided on a straight-line basis over estimated useful lives, which are generally as follows: 

Buildings and improvements	10-37 years
Machinery and equipment, including leases	3-15 years
Leasehold improvements	Term of lease or useful life, whichever is shorter

7

Expenditures for maintenance and repairs are expensed when incurred. Expenditures for renewals and betterments are capitalized.  When assets are sold, or otherwise disposed, the cost and related accumulated depreciation are eliminated and the resulting gain or loss is recognized in operations.  

Intangible Assets, Goodwill and Other Long-lived Assets

Acquisitions

On May 29, 2015, Ply Gem completed an acquisition for cash consideration of approximately $21.0 million to acquire substantially all of the assets of Canyon Stone Inc. ("Canyon Stone"), a manufacturer and distributor of stone veneer and accessories in the United States. Canyon Stone has manufacturing facilities in Olathe, Kansas and Youngsville, North Carolina. The purchase agreement also includes contingent consideration in the form of potential earn-out payments of up to $1.0 million based on Canyon Stone's earnings for fiscal years 2015 through 2017. This acquisition expanded the Company's stone veneer manufacturing footprint across the United States as it complements the existing Ply Gem Stone manufacturing facility. The Company accounted for the transaction as an acquisition in accordance with the provisions of Accounting Standards Codification 805, Business Combinations, which results in a new valuation for the assets and liabilities of Canyon Stone based upon fair values as of the acquisition date.

The Company determined the fair value of the tangible and intangible assets and the liabilities acquired, and recorded goodwill based on the excess of fair value of the acquisition consideration over such fair values, as follows:

(Amounts in thousands)
Accounts receivable	$	3,559
Inventories	712
Prepaid expenses and other current assets	41
Property and equipment	2,019
Intangible assets	9,300
Goodwill	7,642
Accounts payable, accrued expenses and other long-term liabilities	(2,273		)
	$	21,000

The $7.6 million of goodwill was allocated to the Siding, Fencing and Stone segment and the goodwill is expected to be deductible for tax purposes. The Company has recognized a liability of approximately $0.8 million as the estimated acquisition date fair value of the earn-out as of October 1, 2016 and December 31, 2015. This amount is included within other long-term liabilities in the condensed consolidated balance sheets. Any change in the fair value of the contingent consideration subsequent to the acquisition date will be recognized in earnings in the period of change.

Long-lived assets

The Company reviews long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable.  The Company performs an undiscounted operating cash flow analysis to determine if impairment exists.  If an impairment is determined to exist, any related impairment loss is calculated based on the asset’s fair value and the discounted cash flows.

The Company tests for long-lived asset impairment at the following asset group levels: (i) the combined U.S. Siding, Fencing and Stone companies in the Siding, Fencing and Stone segment (“Siding”), (ii) the combined U.S. Windows companies in the Windows and Doors segment (“U.S. Windows”), (iii) the combined Simonton windows companies in the Windows and Doors segment, (iv) Gienow Canada Inc. ("Gienow Canada") (a combined Western Canadian company created by the January 2014 amalgamation of the Company's legacy Western Canadian business and the Gienow entity acquired in April 2013) in the Windows and Doors segment, and (v) Mitten in the Siding, Fencing and Stone segment. For purposes of recognition and measurement of an impairment loss, a long-lived asset or asset group should represent the lowest level for which an entity can separately identify cash flows that are largely independent of the cash flows of other assets and liabilities.  There were no indicators of impairment during the three and nine months ended October 1, 2016.

8

Goodwill and other intangible assets

The Company evaluates goodwill for impairment on an annual basis and whenever events or business conditions warrant.  All other intangible assets are amortized over their estimated useful lives and are assessed for impairment as necessary.  The Company assesses goodwill for impairment at the November month end each year and also at any other date when events or changes in circumstances indicate that the carrying value of these assets may exceed their fair value.  To evaluate goodwill for impairment, the Company estimates the fair value of reporting units considering such factors as discounted cash flows and valuation multiples for comparable publicly traded companies.  A significant reduction in projected sales and earnings, which would lead to a reduction in future cash flows, could indicate potential impairment.  There were no indicators of impairment during the three and nine months ended October 1, 2016 that would trigger an interim impairment test.  The Company will continue to evaluate goodwill during future periods and future declines in the residential housing and repair and remodeling markets could result in goodwill impairments.

Debt Issuance Costs

Debt issuance costs, composed of facility, agency, and certain legal fees associated with issuing new debt financing, are amortized over the contractual term of the related agreement using the effective interest method.  Net debt issuance costs totaled approximately $18.8 million and $22.2 million as of October 1, 2016 and December 31, 2015, respectively, and have been recorded within long-term debt ($16.4 million at October 1, 2016 and $19.3 million at December 31, 2015) and other non-current assets ($2.5 million at October 1, 2016 and $2.9 million at December 31, 2015) in the accompanying condensed consolidated balance sheets. The debt issuance costs included in other long term assets relate to the Senior Secured Asset Based Revolving Credit Facility due 2020 ("ABL Facility"). Amortization of debt issuance costs for the three months ended October 1, 2016 and October 3, 2015 was approximately $0.8 million and $0.8 million, respectively. Amortization of debt issuance costs for the nine months endedOctober 1, 2016 and October 3, 2015 was approximately $2.5 million and $2.3 million, respectively. Amortization of debt issuance costs is recorded in interest expense in the accompanying condensed consolidated statements of operations and comprehensive income.

Income Taxes

The Company utilizes the asset and liability method of accounting for income taxes which requires that deferred tax assets and liabilities be recorded to reflect the future tax consequences of temporary differences between the book and tax basis of various assets and liabilities.  Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.  The effect of changes in tax rates on deferred tax assets and liabilities is recognized as income or expense in the period in which the rate change occurs.  A valuation allowance is established to offset any deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

Estimates are required with respect to, among other things, the appropriate state income tax rates used in the various states that the Company and its subsidiaries are required to file, the potential utilization of operating and capital loss carry-forwards for both federal and state income tax purposes and valuation allowances required, if any, for deferred tax assets that may not be realized in the future.  The Company establishes reserves when, despite our belief that our tax return positions are fully supportable, certain positions could be challenged, and the positions may not be fully sustained.  The Company, along with its U.S. subsidiaries, file a consolidated federal income tax return, separate state income tax returns, combined state returns, and unitary state returns. Gienow Canada and Mitten both file separate Canadian federal income tax returns and separate provincial returns.

9

Tax receivable agreement ("TRA") liability

The TRA liability generally provides for the payment by the Company to the Tax Receivable Entity of 85% of the amount of cash savings, if any, in the U.S. federal, state and local income tax that the Company actually realizes in periods ending after the Company's initial public offering as a result of (i) net operating loss carryovers ("NOLs") from periods ending before January 1, 2013, (ii) deductible expenses attributable to the initial public offering and (iii) deductions related to imputed interest. Since the inception of the TRA liability with the Company’s 2013 initial public offering, the Company has been in a full valuation allowance for federal purposes and had partial valuation allowances on certain state and Canadian jurisdictions. As a result of the Company’s tax valuation allowance position for federal and state purposes, the Company calculated the TRA liability considering (i) current year taxable income only (due to the uncertainty of future taxable income associated with the Company’s cumulative loss position) and (ii) future income due to the expected reversals of deferred tax liabilities. During the three and nine months ended October 1, 2016, the Company released its valuation allowance on its federal deferred tax assets and certain state deferred tax assets for approximately $50.1 million due to positive factors outweighing negative evidence thereby allowing the Company to achieve the “more likely than not” realization threshold. This release thereby eliminated any uncertainty as to future taxable income. Consequently, for purposes of calculating the TRA liability, the Company during the three months ended October 1, 2016 utilized future forecasts of taxable income beyond the 2016 tax year to determine the TRA liability. The Company’s future taxable income estimate was used to determine the cumulative NOLs that are expected to be utilized and the TRA liability was accordingly adjusted using the 85% TRA rate as the Company retains the benefit of 15% of the tax savings.

Environmental

The Company accrues for losses associated with environmental remediation obligations when such losses are probable and reasonably estimable. Environmental remediation obligation accruals are adjusted as further information develops or circumstances change.  Costs of future expenditures for environmental remediation obligations are not discounted to their present value.  Recoveries of environmental remediation costs from other parties are recorded as assets when their receipt is deemed probable.

Commitments and Contingencies

The Company accrues for all direct costs associated with the estimated resolution of contingencies at the earliest date at which it is deemed probable that a liability has been incurred and the amount of such liability can be reasonably estimated.  Costs accrued have been estimated based upon an analysis of potential results, assuming a combination of litigation and settlement strategies and outcomes. Insurance recoveries are recorded as assets when their receipt is deemed probable.

Foreign Currency

Gienow Canada and Mitten, the Company’s Canadian subsidiaries, utilize the Canadian dollar as their functional currency.  For reporting purposes, the Company translates the assets and liabilities of its foreign entities at the exchange rates in effect at period-end.  Net sales and expenses are translated using average exchange rates in effect during the period.  Gains and losses from foreign currency translation are credited or charged to accumulated other comprehensive income or loss in the accompanying condensed consolidated balance sheets.

The Company recorded a loss from foreign currency transactions of approximately $0.1 million and $1.1 million for the three months ended October 1, 2016 and October 3, 2015, respectively. The Company recorded a gain from foreign currency transactions of approximately $0.7 million for the nine months ended October 1, 2016 and a loss of approximately $2.1 million for the nine months ended October 3, 2015. During the nine months ended October 1, 2016, accumulated other comprehensive income (loss) included a currency translation gain of approximately $4.1 million and a loss of approximately $11.3 million for the nine months ended October 3, 2015.

Derivative Financial Instruments

As of October 1, 2016, the Company had entered into foreign currency forward contract agreements to hedge approximately $78.1 million of its 2016 and 2017 non-functional currency inventory purchases to protect the Company from variability in cash flows attributable to changes in the U.S. dollar relative to the Canadian dollar.

10

The Company has designated these forward contracts as cash flow hedges. As a cash flow hedge, unrealized gains are recognized as assets while unrealized losses are recognized as liabilities. These forward contract agreements are highly correlated to the changes in foreign currency rates to which the Company is exposed. Unrealized gains and losses on these agreements are designated as effective or ineffective. The effective portion of such gains or losses is recorded as a component of accumulated other comprehensive income or loss, while the ineffective portion of such gains or losses is recorded as a component of cost of goods sold. Future realized gains and losses in connection with each inventory purchase will be reclassified from accumulated other comprehensive income or loss to cost of goods sold.

The changes in fair values of derivatives that have been designated and qualify as cash flow hedges are recorded in accumulated other comprehensive income or loss and are reclassified into cost of goods sold in the same period the hedged item affects earnings. Due to the high degree of effectiveness between the hedging instruments and the underlying exposures being hedged, fluctuations in the value of the derivative instrument are generally offset by changes in the fair value or cash flows of the underlying exposures being hedged. The changes in the fair value of derivatives that do not qualify as effective are immediately recognized in earnings.

The gains and losses on derivative contracts that are reclassified from accumulated other comprehensive income or loss to current period earnings are included in the line item in which the hedged item is recorded in the same period the forecasted transaction affects earnings. As of October 1, 2016, approximately $0.3 million of the deferred net asset on derivative instruments included in accumulated other comprehensive loss is expected to be reclassified to cost of goods sold during the next twelve months. This expectation is based on the expected timing of the occurrence of the hedged forecasted transactions. During the three and nine months ended October 1, 2016, the Company recognized $0.2 million and $0.5 million, respectively, within earnings as an increase to cost of goods sold in the condensed consolidated statement of operations and comprehensive income. During the three and nine months ended October 3, 2015, the Company recognized $1.8 million and $3.9 million, respectively, within earnings as a reduction of cost of goods sold in the condensed consolidated statement of operations and comprehensive income.

The fair value of the foreign currency forward contract agreements are estimated using industry standard valuation models using market-based observable inputs, including spot rates, forward points, interest rates and volatility inputs (Level 2). A summary of the recorded asset and liability included in the accompanying condensed consolidated balance sheets is as follows:

Fair Value Measurement

The accounting standard for fair value discusses valuation techniques, such as the market approach (comparable market prices), the income approach (present value of future income or cash flows), and the cost approach (cost to replace the service capacity of an asset or replacement cost). The standard utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels:

• Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities.

• Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.

• Level 3: Inputs that reflect the reporting entity’s own assumptions.

The hierarchy requires the use of observable market data, when available, and to minimize the use of unobservable inputs when determining fair value.  The fair value of the long-term debt instruments was determined by utilizing available market information.  The carrying value of the Company’s other assets and liabilities approximates their fair value. The Company’s population of recurring financial assets and liabilities subject to fair value measurements and the necessary disclosures are as follows:

Earnings (Loss) Per Common Share

Basic earnings (loss) per share ("EPS") is computed based upon weighted-average shares outstanding during the period. Dilutive earnings per share is computed consistently with the basic computation while giving effect to all dilutive potential common shares and common share equivalents that were outstanding during the period. Ply Gem Holdings uses the treasury stock method to reflect the potential dilutive effect of unvested stock awards and unexercised options.

The computation of the dilutive effect of other potential common shares included options and unvested restricted stock representing approximately 0.2 million and 0.1 million shares of common stock for the three and nine months endedOctober 1, 2016, respectively. The computation of the dilutive effect of other potential common shares included options and unvested restricted stock representing approximately 0.1 million and 0.1 million shares of common stock for the three and nine months ended October 3, 2015, respectively.

New Accounting Pronouncements

In August 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 addresses how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230, Statement of Cash Flow, and Other Topics. ASU 2016-15 is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2017. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements.

In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting. The amendments in this updated guidance include changes to simplify the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This guidance is effective for fiscal years beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is permitted. The Company is in the process of evaluating the potential impacts of this new guidance on its consolidated financial statements.

In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606), Principal versus Agent Considerations (Reporting Revenue Gross versus Net). This update provides guidance on recording revenue on a gross basis versus a net basis based on the determination of whether an entity is a principal or an agent when another party is involved in providing goods or services to a customer. The amendments in this update affect the guidance in ASU No. 2014-09 and are effective in the same timeframe as ASU No. 2014-09 as discussed below.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The core principal of the guidance is that an entity should recognize assets and liabilities arising from a lease for both financing and operating leases, along with additional qualitative and quantitative disclosures. The standard will be effective for fiscal years beginning after December 15, 2018, including interim periods within such fiscal years. Early adoption is permitted. The guidance is to be applied using a modified retrospective transition method with the option to elect a package of practical expedients. The Company is currently evaluating the impact of the adoption of this accounting standard update on its internal processes, operating results and financial reporting. The impact is currently not known or reasonably estimable.

12

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which completes the joint effort by the FASB and the International Accounting Standards Board to clarify the principles for recognizing revenue and improve financial reporting by creating common revenue recognition guidance for U.S. generally accepted accounting principles ("GAAP") and International Financial Reporting Standards ("IFRS"). ASU 2014-09 provides enhancements to the quality and consistency of how revenue is reported while also improving comparability in the financial statements of companies reporting using IFRS and GAAP. The core principle of this update is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB finalized a one-year deferral of the effective date of the new revenue recognition standard. The new standard will become effective for Ply Gem beginning with the first quarter of 2018 and can be adopted either retrospectively to each prior reporting period presented or as a cumulative effect adjustment as of the date of adoption. The method of adoption has not been determined yet by the Company. The Company is currently reviewing the revised guidance and assessing the potential impact on the consolidated financial statements.

2.   GOODWILL

The Company records the excess of the fair value of the acquisition consideration over the net tangible and intangible assets of acquired companies as goodwill.  The Company performs an annual test for goodwill impairment at the November month end each year and also at any other date when events or changes in circumstances indicate that the carrying value of these assets may exceed their fair value.  The Company has defined its reporting units and performs the impairment testing of goodwill at the operating segment level.  The Company has two reporting units: (1) Siding, Fencing and Stone and (2) Windows and Doors.  Separate valuations are performed for each of these reporting units in order to test for impairment.    

The Company uses the two-step method to determine goodwill impairment.  If the carrying amount of a reporting unit exceeds its fair value (“Step One”), the Company measures the possible goodwill impairment based upon a hypothetical allocation of the fair value estimate of the reporting unit to all of the underlying assets and liabilities of the reporting unit, including previously unrecognized intangible assets (“Step Two”).  The excess of the reporting unit’s fair value over the amounts assigned to its assets and liabilities is the implied fair value of goodwill.  An impairment loss is recognized to the extent that a reporting unit’s recorded goodwill exceeds the implied fair value of goodwill. The Company has elected not to utilize the qualitative Step Zero impairment assessment. There was no goodwill impairment for the year ended December 31, 2015 and no impairment indicators which would trigger an interim impairment test during the three and nine months ended October 1, 2016. However, the Company will continue to evaluate goodwill during future periods and future declines in the residential housing and repair and remodeling markets or the Company's market capitalization could result in goodwill impairments.  

To determine the fair value of its reporting units, the Company equally considers both the income and market valuation methodologies.  The income valuation methodology uses the fair value of the cash flows that the reporting unit can be expected to generate in the future. This method requires management to project revenues, operating expenses, working capital investment, capital spending and cash flows for the reporting unit over a multi-year period as well as determine the weighted average cost of capital to be used as the discount rate.  The Company also utilizes the market valuation method to estimate the fair value of the reporting units by utilizing comparable public company multiples.  These comparable public company multiples are then applied to the reporting unit’s financial performance.  The market approach is more volatile as an indicator of fair value as compared to the income approach as internal forecasts and projections have historically been more stable.  Since each approach has its merits, the Company equally weights the approaches to balance the internal and external factors affecting the Company’s fair value.

The Company’s fair value estimates of its reporting units and goodwill are sensitive to a number of assumptions including discount rates, cash flow projections, operating margins, and comparable market multiples.  In order to accurately forecast future cash flows, the Company estimates single family housing starts and the repair and remodeling market's growth rates.  However, there is no assurance that: (1) valuation multiples will not decline, (2) discount rates will not increase, or (3) the earnings, book values or projected earnings and cash flows of the Company's reporting units will not decline.

2015 Debt Transaction

On November 5, 2015, Ply Gem Industries entered into a second amended and restated ABL Facility. Among other things, the second amended and restated ABL Facility: (i) increased the overall facility to $350.0 million, (ii) provided an accordion feature of $50.0 million, and (iii) established the applicable margin for borrowings under the ABL Facility to a range of 1.25% to 2.00% for Eurodollar rate loans, depending on availability. All outstanding loans under the second amended and restated ABL Facility are due and payable in full on November 5, 2020.

6.50% Senior Notes due 2022

15

On January 30, 2014, Ply Gem Industries issued $500.0 million aggregate principal amount of 6.50% Senior Notes due 2022 (the "6.50% Senior Notes") at par. On September 19, 2014, Ply Gem Industries issued an additional $150.0 million aggregate principal amount of 6.50% Senior Notes at an issue price of 93.25%. Interest accrues at 6.50% per annum and is paid semi-annually on February 1 and August 1 of each year. All issued and outstanding 6.50% Senior Notes are registered under the Securities Act. The 6.50% Senior Notes will mature on February 1, 2022.

Prior to February 1, 2017, Ply Gem Industries may redeem up to 40% of aggregate principal amount of the 6.50% Senior Notes with the net cash proceeds from certain equity offerings at a redemption price equal to 106.50% of the aggregate principal amount of the 6.50% Senior Notes to be redeemed, plus accrued and unpaid interest, if any, provided that at least 50% of the aggregate principal amount of the 6.50% Senior Notes remains outstanding after the redemption. Prior to February 1, 2017, Ply Gem Industries may redeem the 6.50% Senior Notes, in whole or in part, at a redemption price equal to 100% of the principal amount plus a “make-whole” premium plus accrued and unpaid interest, if any. At any time on or after February 1, 2017, Ply Gem Industries may redeem the 6.50% Senior Notes, in whole or in part, at declining redemption prices set forth in the indenture governing the 6.50% Senior Notes plus, in each case, accrued and unpaid interest, if any, to the redemption date. The effective interest rate for the 6.50% Senior Notes is 8.39% after considering each of the different interest expense components of this instrument, including the coupon payment and the deferred debt issuance costs.

The 6.50% Senior Notes are fully and unconditionally and jointly and severally guaranteed on a senior unsecured basis by Ply Gem Holdings and all of the wholly-owned domestic subsidiaries of Ply Gem Industries (the “Guarantors”).  The indenture governing the 6.50% Senior Notes contains certain covenants that limit the ability of Ply Gem Industries and its restricted subsidiaries to incur additional indebtedness, pay dividends or make other distributions or repurchase or redeem their stock, make loans and investments, sell assets, incur certain liens, enter into agreements restricting their ability to pay dividends, enter into transactions with affiliates, and consolidate, merge or sell assets.  In particular, Ply Gem Industries and its restricted subsidiaries may not incur additional debt (other than permitted debt (as defined in the indenture) in limited circumstances) unless, after giving effect to such incurrence, the consolidated interest coverage ratio of Ply Gem Industries would be at least 2.00 to 1.00.  

In the absence of satisfying the consolidated interest coverage ratio test, Ply Gem Industries and its restricted subsidiaries may only incur additional debt under certain circumstances, including, but not limited to, debt under credit facilities (as defined in the indenture) (x) in an amount not to exceed the greater of (a) $350.0 million and (b) the borrowing base (as defined in the indenture) and (y) in an amount not to exceed the greater of (A) $575.0 million and (B) the aggregate amount of indebtedness (as defined in the indenture) that would cause the consolidated secured debt ratio (as defined in the indenture) to be equal to 4.00 to 1.00; purchase money indebtedness in an aggregate amount not to exceed the greater of (x) $35.0 million and (y) 10% of consolidated net tangible assets (as defined in the indenture) at any one time outstanding; debt of foreign subsidiaries in an aggregate amount not to exceed the greater of (x) $60.0 million and (y) 15% of consolidated net tangible assets (as defined in the indenture) at any one time outstanding; debt pursuant to a general basket in an aggregate amount at any one time outstanding not to exceed the greater of (x) $75.0 million and (y) 20% of consolidated net tangible assets; and the refinancing of debt under certain circumstances.

Term Loan Facility due 2021

On January 30, 2014, Ply Gem Industries entered into a credit agreement governing the terms of its $430.0 million Term Loan Facility. Ply Gem Industries originally borrowed $430.0 million under the Term Loan Facility on January 30, 2014, with an original discount of approximately $2.2 million, yielding proceeds of approximately $427.9 million. The Term Loan Facility will mature on January 30, 2021. The Term Loan Facility requires scheduled quarterly payments in an aggregate annual amount equal to 1.00% of the original aggregate principal amount of the Term Loan Facility with the balance due at maturity. Interest on outstanding borrowings under the Term Loan Facility is paid quarterly.

Borrowings under the Term Loan Facility bear interest at a rate equal to, at Ply Gem Industries’ option, either (a) a base rate determined by reference to the highest of (i) the prime rate of the administrative agent under the credit agreement, (ii) the federal funds rate plus 0.50% and (iii) the adjusted LIBO rate for a one-month interest period plus 1.00% or (b) a LIBO rate determined by reference to the cost of funds for eurocurrency deposits in dollars for the interest period relevant to such borrowing, adjusted for certain additional costs, subject to a 1.00% floor, plus, in each case, an applicable margin of 3.00% for any eurocurrency loan and 2.00% for any alternate base rate loan. As of October 1, 2016, the Company's interest rate on the Term Loan Facility was 4.00%. The effective interest rate for the Term Loan is 7.38% after considering each of the different interest expense components of this instrument, including the coupon payment, the deferred debt issuance costs and the original issue discount.

16

The Term Loan Facility allows Ply Gem Industries to request one or more incremental term loan facilities in an aggregate amount not to exceed the greater of (x) $140.0 million and (y) an amount such that Ply Gem Industries’ consolidated senior secured debt ratio (as defined in the credit agreement), on a pro forma basis, does not exceed 3.75 to 1.00, in each case, subject to certain conditions and receipt of commitments by existing or additional financial institutions or institutional lenders.

The Term Loan Facility requires Ply Gem Industries to prepay outstanding term loans, subject to certain exceptions, with: (i) 50% (which percentage will be reduced to 25% if our consolidated senior secured debt ratio is equal or less than 2.50 to 1.00 but greater than 2.00 to 1.00 and to 0% if our consolidated senior secured debt ratio is equal to or less than 2.00 to 1.00) of our annual excess cash flow (as defined in the credit agreement), to the extent such excess cash flow exceeds $15.0 million; (ii) 100% of the net cash proceeds of certain non-ordinary course asset sales or certain insurance and condemnation proceeds, in each case subject to certain exceptions and reinvestment rights; and (iii) 100% of the net cash proceeds of certain issuances of debt, other than proceeds from debt permitted under the Term Loan Facility. Ply Gem Industries may voluntarily repay outstanding loans under the Term Loan Facility at any time without premium or penalty, other than customary “breakage” costs with respect to LIBOR loans. As of and for the year ended December 31, 2015, the Company's consolidated senior secured debt ratio was 1.97 and as a result no excess cash flow payment under the Term Loan Facility was required. However, the Company elected on March 10, 2016 and August 4, 2016 to voluntarily prepay $30.0 million on each date on the Term Loan Facility to reduce its outstanding indebtedness. The Company further elected on November 4, 2016 to voluntarily pay an additional $100.0 million on the Term Loan Facility to further reduce its outstanding indebtedness bringing our cumulative voluntary 2016 Term Loan Facility payments to $160.0 million.

The Term Loan Facility is secured on a first-priority lien basis by the stock of Ply Gem Industries and by substantially all of the assets (other than the assets securing the obligations under the ABL Facility, which primarily consist of accounts receivable, inventory, cash, deposit accounts, securities accounts, chattel paper, contract rights, instruments, documents related thereto and proceeds of the foregoing) of Ply Gem Industries and the Guarantors that are subsidiaries of Ply Gem Industries and on a second-priority lien basis by the assets that secure the ABL Facility.

The Term Loan Facility includes negative covenants, subject to certain exceptions, that are substantially the same as the negative covenants in the 6.50% Senior Notes but does not contain any restrictive financial covenants. The Term Loan Facility also restricts the ability of Ply Gem Industries’ subsidiaries to enter into agreements restricting their ability to grant liens to secure the Term Loan Facility and contains a restriction on changes in fiscal year.

Senior Secured Asset Based Revolving Credit Facility due 2020

On November 5, 2015, Ply Gem Holdings, Inc., Ply Gem Industries, Inc., Gienow Canada Inc., and Mitten Inc. (together with Gienow, the “Canadian Borrowers”) entered into a second amended and restated credit agreement governing the ABL Facility. Among other things, the second amendment and restatement of the credit agreement governing the ABL Facility: (i) increased the overall facility to $350.0 million from $300.0 million, (ii) established an accordion feature of $50.0 million, (iii) reduced the applicable margin for borrowings under the ABL Facility to a range from 1.25% to 2.00% for Eurodollar rate loans, depending on availability, and (iv) extended the maturity until November 5, 2020. Under the ABL Facility, $300.0 million is available to Ply Gem Industries and $50.0 million is available to the Canadian Borrowers. The following summary describes the ABL Facility after giving effect to the second amendment and restatement. As a result of the November 2015 ABL Facility amendment in which the loan syndication consisted of previous members who either maintained or increased their position as well as new syndication members, the Company capitalized new debt issuance costs of $1.5 million and will amortize these costs through 2020.

Borrowings under the ABL Facility bear interest at a rate per annum equal to, at Ply Gem Industries’ option, either (a) a base rate determined by reference to the higher of (1) the corporate base rate of the administrative agent under the ABL Facility and (2) the federal funds rate plus 0.5% or (b) a Eurodollar rate determined by reference to the costs of funds for U.S. dollar deposits for the interest period relevant to such borrowing adjusted for certain additional costs, in each case plus an applicable margin.  The initial applicable margin for borrowings under the ABL Facility was 0.50% for base rate loans and 1.50% for Eurodollar rate loans.  The applicable margin for borrowings under the ABL Facility is subject to step ups and step downs based on average excess availability under the ABL Facility.  Swingline loans bear interest at a rate per annum equal to the base rate plus the applicable margin.

In addition to paying interest on outstanding principal under the ABL Facility, Ply Gem Industries is required to pay a commitment fee in respect of the unutilized commitments thereunder, which fee will be determined based on utilization of the ABL Facility (increasing when utilization is low and decreasing when utilization is high) multiplied by a commitment fee rate determined by reference to average excess availability under the ABL Facility. The commitment fee rate during any fiscal quarter is 0.375% when average excess availability is greater than $100.0 million for the preceding fiscal quarter and 0.25% when average availability is less than or equal to $100.0 million for the preceding fiscal quarter.  Ply Gem Industries must also pay customary letter of credit fees equal to the applicable margin on Eurodollar loans and agency fees.   As of October 1, 2016, the Company’s interest rate on the ABL Facility was approximately 1.88%.  The ABL Facility requires that if (a) excess availability is less than the greater of (x) 10.0% of the lower of the borrowing base and the aggregate commitments and (y) $25.0 million or (b) any event of default has occurred and is continuing, Ply Gem Industries must comply with a minimum fixed charge coverage ratio test of 1.0 to 1.0.  If the excess availability under the ABL Facility is less than the greater of (a) 12.5% of the lesser of the borrowing base and the aggregate commitments and (b) $30.0 million ($27.5 million for the months of January, February, March and April) for a period of 5 consecutive days or an event of default has occurred and is continuing, all cash from Ply Gem Industries material deposit accounts (including all concentration accounts) will be swept daily into a collection account controlled by the administrative agent under the ABL Facility and used to repay outstanding loans and cash collateralize letters of credit.

All obligations under the ABL Facility are unconditionally guaranteed by Ply Gem Holdings and substantially all of Ply Gem Industries’ existing and future, direct and indirect, wholly owned domestic subsidiaries.  All obligations under the ABL Facility, and the guarantees of those obligations, are secured, subject to certain exceptions, by substantially all of the assets of Ply Gem Industries and the guarantors, including a first-priority security interest in personal property consisting of accounts receivable, inventory, cash, deposit accounts, and certain related assets and proceeds of the foregoing and a second-priority security interest in, and mortgages on, substantially all of Ply Gem Industries’ and the Guarantors’ material owned real property and equipment and all assets that secure the Term Loan Facility on a first-priority basis.  In addition to being secured by the collateral securing the obligations of Ply Gem Industries under the domestic collateral package, the obligations of the Canadian Borrowers, which are borrowers under the Canadian sub-facility under the ABL Facility, are also secured by a first-priority security interest in substantially all of the assets of such Canadian subsidiaries, plus additional mortgages in Canada, and a pledge by Ply Gem Industries of the remaining 35% of the equity interests of the Canadian Borrowers pledged only to secure the Canadian sub-facility.

The ABL Facility contains certain covenants that limit Ply Gem Industries’ ability and the ability of Ply Gem Industries’ subsidiaries to incur additional indebtedness, pay dividends or make other distributions or repurchase or redeem their stock, make loans and investments, sell assets, incur certain liens, enter into transactions with affiliates, and consolidate, merge or sell assets.  

As of October 1, 2016, Ply Gem Industries had approximately $339.4 million of contractual availability and approximately $274.0 million of borrowing base availability under the ABL Facility, reflecting $0.0 million of borrowings outstanding and approximately $10.6 million of letters of credit and priority payables reserves.

Loss on debt modification or extinguishment

During both March and August 2016, the Company made voluntarily payments of $30.0 million on the Term Loan Facility to reduce its outstanding indebtedness as allowable under the terms of the Term Loan Facility totaling $60.0 million during 2016. The Company performed an analysis to determine the proper accounting treatment for each of these voluntary payments by evaluating the change in cash flows and determined that there were no changes in creditors as a result of the payments. Consequently, the Company recognized a loss on debt modification or extinguishment of approximately $2.3 million and $4.7 million for the three and nine months endedOctober 1, 2016, respectively, reflecting the proportionate write-off of the related debt discount and debt issuance costs associated with each $30.0 million payment, as summarized in the table below.

(Amounts in thousands)	For the three months ended				For the nine months ended
	October 1, 2016		October 3, 2015		October 1, 2016		October 3, 2015

7.   COMMITMENTS AND CONTINGENCIES

Indemnifications

In connection with the Ply Gem acquisition, in which Ply Gem Industries was acquired from Nortek, Inc. (“Nortek”) in February 2004, Nortek has agreed to indemnify the Company for certain liabilities as set forth in the stock purchase agreement governing the Ply Gem acquisition.  In the event Nortek is unable to satisfy amounts due under these indemnifications, the Company would be liable.  The Company believes that Nortek has the financial capacity to honor its indemnification obligations and therefore does not anticipate incurring any losses related to liabilities indemnified by Nortek under the stock purchase agreement.  A receivable related to this indemnification has been recorded in other long-term assets of approximately $1.5 million and $1.8 million at October 1, 2016 and December 31, 2015, respectively.  As of October 1, 2016 and December 31, 2015, the Company has recorded liabilities related to these indemnifications of approximately $0.5 million and $0.5 million, respectively, in current liabilities and $1.0 million and $1.3 million, respectively, in long-term liabilities, consisting of the following:

(Amounts in thousands)	October 1, 2016		December 31, 2015
Product claim liabilities	$	138	$	138
Multi-employer pension plan withdrawal liability	823		960
Other	528		664
	$	1,489	$	1,762

Warranty claims

The Company sells a number of products and offers a number of warranties.  The specific terms and conditions of these warranties vary depending on the product sold.  The Company estimates the costs that may be incurred under their warranties and records a liability for such costs at the time of sale.  Factors that affect the Company’s warranty liabilities include the number of units sold, historical and anticipated rates of warranty claims, cost per claim and new product introduction.  The Company assesses the adequacy of the recorded warranty claims and adjusts the amounts as necessary.  As of October 1, 2016 and December 31, 2015, warranty liabilities of approximately $19.4 million and $16.6 million, respectively, have been recorded in current liabilities and approximately $57.4 million and $59.9 million, respectively, have been recorded in long term liabilities in the Company's condensed consolidated balance sheets.

Environmental

The Company is subject to United States and Canadian federal, state, provincial and local laws and regulations relating to pollution and the protection of the environment, including those governing emissions to air, discharges to water, use, storage and transport of hazardous materials, storage, treatment and disposal of waste, remediation of contaminated sites, and protection of worker health and safety. From time to time, the Company's facilities are subject to investigation by governmental regulators. In addition, the Company has been identified as one of many potentially responsible parties for contamination present at certain offsite locations to which it or its predecessors are alleged to have sent hazardous materials for recycling or disposal. The Company may be held liable, or incur fines or penalties, in connection with such requirements or liabilities for, among other things, releases of hazardous substances occurring on or emanating from current or formerly owned or operated properties or any associated offsite disposal location, or for known or newly-discovered contamination at any of the Company's properties from activities conducted by us or previous occupants. The amount of any liability, fine or penalty may be material, and certain environmental laws impose strict, and under certain circumstances joint and several, liability for the cost of addressing releases of hazardous substances upon certain classes of persons, including site owners or operators and persons that disposed or arranged for the disposal of hazardous substances at contaminated sites.

MW Manufacturers Inc. (“MW”), a subsidiary of MWM Holding, Inc., entered into an Administrative Order on Consent (the “Consent Order”), effective September 12, 2011, with the United States Environmental Protection Agency (“EPA”), Region III, under Section 3008(h) of the Resource Conservation and Recovery Act ("RCRA"), with respect to its Rocky Mount, Virginia property.  During 2011, as part of the Consent Order, MW provided the EPA, among other things, a RCRA Facility Investigation Workplan (the “Workplan”) as well as a preliminary cost estimate of approximately $1.8 million for the predicted assessment, remediation and monitoring activities to be conducted pursuant to the Consent Order over the remediation period, which is currently estimated through 2023. During 2012, the EPA approved the Workplan, and MW is currently implementing the Workplan. The Company has recorded approximately $0.3 million of this environmental liability within current liabilities and approximately $1.2 million within other long-term liabilities in the Company’s condensed consolidated balance sheet at October 1, 2016 and December 31, 2015.  The Company will adjust this environmental remediation liability in future periods, if necessary, as further information develops or circumstances change.

Certain liabilities with respect to this contamination relate to the previous closure of an underground storage tank and were assumed by U.S. Industries, Inc., pursuant to its indemnity obligation under the stock purchase agreement dated August 11, 1995, whereby U.S. Industries, Inc. sold the stock of MW to FPI Acquisition Corp. (“Fenway Partners”). As the successor-in-interest of Fenway Partners, the Company is similarly indemnified by U.S. Industries, Inc. Notwithstanding this indemnity, however, under applicable Federal and State laws, MW, and the Company as its parent, could be held liable for all or part of the costs associated with the matter under certain circumstances. Moreover, the Company’s ability to seek indemnification from U.S. Industries, Inc. is limited by the terms and limits of the indemnity as well as the strength of U.S. Industries, Inc. is, however, limited by the terms and limits of the indemnity as well as the strength of U.S. Industries, Inc.’s financial condition, which could change in the future.  As of October 1, 2016, no recovery has been recognized on the Company’s condensed consolidated balance sheet, but the Company will actively pursue this indemnity in future periods and will recognize future recoveries in the period in which they become probable.

The State of Nebraska is investigating certain groundwater contamination in northern York, Nebraska, comprised primarily of volatile organic compounds (VOC) (predominantly trichloroethene (TCE)). In December 2013, the EPA announced its proposal to add this groundwater contamination site to the Superfund National Priorities List (NPL) after it was referred to the EPA by the State of Nebraska. Sampling was conducted at the Kroy Building Products, Inc. (“Kroy”) facility in York, Nebraska during the first quarter of 2010. In February 2015, the EPA sent a request for information pursuant to Section 104 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), and Kroy has responded to this request for information. Given the preliminary stage of this matter, the Company has not recorded a liability for this matter in its condensed consolidated balance sheet as of October 1, 2016. Alcan Aluminum Corporation (“Alcan”) has assumed the obligation to indemnify the Company with respect to certain liabilities for environmental contamination of the Kroy facility occurring prior to 1994. Notwithstanding this indemnity, however, under applicable Federal and State laws, Kroy, and Ply Gem as its parent, could be held liable for all or part of the costs associated with the matter under certain circumstances. Moreover, the ability of Kroy and Ply Gem to seek indemnification may be limited by the terms and limits of the indemnity as well as the strength of Alcan’s financial condition, which could change in the future.

The Company is currently involved in environmental proceedings involving Gienow Canada Inc. (f/k/a Ply Gem Canada, Inc.) and Alberta Environment (arising from subsurface contamination discovered at our Calgary, Alberta property) for which the Company has a $0.1 million liability included in its condensed consolidated balance sheet, and the Company may in the future be subject to environmental proceedings involving Thermal-Gard, Inc. (arising from groundwater contamination in Punxsutawney, Pennsylvania), Mastic Home Exteriors, Inc. (“MHE”) (relating to a closed landfill site in Sidney, Ohio as well as participating as a potentially responsible party in nine contaminated sites in Indiana, Ohio and South Carolina), and Simonton (relating to closed lagoons and certain contamination in Paris, Illinois as well as certain contamination associated with certain 7-Eleven convenience food stores). Under the stock purchase agreement governing the MHE acquisition, Alcoa Securities Corporation and Alcoa, Inc. are to indemnify the Company for certain environmental liabilities in excess of $2.5 million including liabilities relating to the landfill site in Sidney, Ohio and the nine contaminated sites in Indiana, Ohio and South Carolina. Under the stock purchase agreement governing the Simonton acquisition, Fortune Brands Windows & Doors, Inc., is to indemnify the Company for any environmental claims associated with the 7-Eleven convenience food stores. The Company's ability to seek indemnification or enforce these and other obligations is, however, limited by the strength of the financial condition of the indemnitor or responsible party, which could change in the future, as well as the terms and limits of any such indemnities or obligations.

Based on current information, the Company is not aware of any compliance obligations, claims, releases or investigations that will have a material adverse effect on our results of operations, cash flows or financial position except as otherwise disclosed in the Company's condensed consolidated financial statements. However, there can be no guarantee that previously known or newly-discovered matters or any inability to enforce our available indemnification rights against previous owners of the Company, its subsidiaries, or their businesses or properties will not result in material costs or liabilities. While the purchase agreements governing certain of our acquisitions provide that the sellers will indemnify us, subject to certain limitations, for certain environmental liabilities, our ability to seek indemnification from the respective sellers is limited by various factors, including the financial condition of the indemnitor or responsible party as well as by the terms and limits of such indemnities or obligations. As a result, there can be no assurance that we could receive any indemnification from the sellers, and any related environmental liabilities, costs or penalties could have a material adverse effect on our financial condition and results of operations.

Self-insured risks

The Company maintains a broad range of insurance policies which include general liability insurance coverage and workers compensation. These insurance policies protect the Company against a portion of the risk of loss from claims. However, the Company retains a portion of the overall risk for such claims through its self-insured per occurrence and aggregate retentions, deductibles, and claims in excess of available insurance policy limits. The Company's general liability insurance includes coverage for certain damages arising out of product design and manufacturing defects. The Company's insurance coverage is generally subject to a per occurrence retention.

The Company reserves for costs associated with claims, as well as incurred but not reported losses (“IBNR”), based on an outside actuarial analysis of its historical claims. These estimates make up a significant portion of the Company's liability and are subject to a high degree of uncertainty due to a variety of factors, including changes in type of claims, claims reporting and resolution patterns, frequency and timing of claims, third party recoveries, estimates of claim values, claims management expenses (including legal fees and expert fees), insurance industry practices, the regulatory environment, and legal precedent. Adjustments to estimated reserves are recorded in the period in which the change in estimate occurs.

Litigation

During the past several years, the Company incurred increased litigation expense primarily related to the claims discussed below. The Company believes it has valid defenses to the outstanding claims discussed below and will vigorously defend all such claims; however, litigation is subject to many uncertainties and there cannot be any assurance that the Company will ultimately prevail or, in the event of an unfavorable outcome or settlement of litigation, that the ultimate liability would not be material and would not have a material adverse effect on the business, results of operations, cash flows or financial position of the Company.

In John Gulbankian v. MW Manufacturers, Inc. (“Gulbankian”), a purported class action filed in March 2010 in the United States District Court for the District of Massachusetts, plaintiffs, on behalf of themselves and all others similarly situated, alleged damages as a result of the defective design and manufacture of certain MW vinyl clad windows. In Eric Hartshorn and Bethany Perry v. MW Manufacturers, Inc. (“Hartshorn”), a purported class action filed in July 2012 in the District Court, plaintiffs, on behalf of themselves and all others similarly situated, alleged damages as a result of the defective design and manufacture of certain MW vinyl clad windows. On April 22, 2014, plaintiffs in both the Gulbankian and Hartshorn cases filed a Consolidated Amended Class Action Complaint, making similar claims against all MW vinyl clad windows.

MW entered into a settlement agreement with plaintiffs as of April 18, 2014 to settle both the Gulbankian and Hartshorn cases on a nationwide basis (the “Vinyl Clad Settlement Agreement”). The Vinyl Clad Settlement Agreement provides that this settlement applies to any and all MW vinyl clad windows manufactured from January 1, 1987 through May 23, 2014, and provides for a cash payment for eligible consumers submitting qualified claims showing, among other requirements, certain damage to their MW vinyl clad windows. The period for submitting qualified claims is the later of: (i) May 28, 2016, or (ii) the last day of the warranty period for the applicable window. On December 29, 2014, the District Court granted final approval of this settlement, as well as MW’s payment of attorneys' fees and costs to plaintiffs' counsel in the amount of $2.5 million, issuing a Final Approval Order, Final Judgment, and Order of Dismissal with Prejudice (the "Final Approval Order"). A notice of appeal of the Final Approval Order (the “Appeal”) was given by certain objectors to the settlement, and on May 6, 2015, MW entered into a settlement agreement with, among others, the objectors to fully and finally resolve their claims, including the dismissal of Karl Memari v. Ply Gem Prime Holdings, Inc. et al., another lawsuit seeking class certification with respect to MW's vinyl clad windows, making the Vinyl Clad Settlement Agreement final and binding on the parties. The Company and MW deny all liability in the settlements with respect to the facts and claims alleged. The Company, however, is aware of the substantial burden, expense, inconvenience and distraction of continued litigation, and therefore agreed to settle these matters.

As a result of the Vinyl Clad Settlement Agreement, the Company recognized a $5.0 million expense during the year ended December 31, 2014 within selling, general, and administrative expenses in the Company’s consolidated statement of operations and comprehensive income (loss) in the Company's Windows and Doors segment. It is possible that the Company may incur costs in excess of the recorded amounts; however, the Company currently expects that the total net cost will not exceed $5.0 million. As of October 1, 2016, approximately $1.4 million of this liability is currently outstanding with $0.7 million as a current liability within accrued expenses and $0.7 million as a noncurrent liability within other long-term liabilities in the Company’s condensed consolidated balance sheet.

In Anthony Pagliaroni et al. v. Mastic Home Exteriors, Inc. and Deceuninck North America, LLC, a purported class action filed in January 2012 in the United States District Court for the District of Massachusetts, plaintiffs, on behalf of themselves and all others similarly situated, allege damages as a result of the defective design and manufacture of Oasis composite deck and railing, which was manufactured by Deceuninck North America, LLC (“Deceuninck”) and sold by Mastic Home Exteriors, Inc. (“MHE”). The plaintiffs seek a variety of relief, including (i) economic and compensatory damages, (ii) treble damages, (iii) punitive damages, and (iv) attorneys' fees and costs of litigation. The damages sought in this action have not yet been quantified. The hearing regarding plaintiffs’ motion for class certification was held on March 10, 2015, and the District Court denied plaintiffs’ motion for class certification on September 22, 2015. On October, 6, 2015, plaintiffs filed a petition for interlocutory appeal of the denial of class certification to the U.S. Court of Appeals for the First Circuit, and on April 12, 2016, the Court of Appeals denied this petition for appeal. Deceuninck, as the manufacturer of Oasis deck and railing, has agreed to indemnify MHE for certain liabilities related to this claim pursuant to the sales and distribution agreement, as amended, between Deceuninck and MHE. MHE's ability to seek indemnification from Deceuninck is, however, limited by the terms and limits of the indemnity as well as the strength of Deceuninck's financial condition, which could change in the future.

In rePly Gem Holdings, Inc. Securities Litigation isa purported federal securities class action filed on May 19, 2014 in the United States District Court for the Southern District of New York against Ply Gem Holdings, Inc., several of its directors and officers, and the underwriters associated with the Company’s initial public offering ("IPO"). It is filed on behalf of all persons or entities, other than the defendants, who purchased the common shares of the Company pursuant and/or traceable to the Company’s IPO and seeks remedies under Sections 11 and 15 of the Securities Act of 1933, alleging that the Company’s Form S-1 registration statement was negligently prepared and materially inaccurate, containing untrue statements of material fact and omitting material information which was required to be disclosed. The plaintiffs seek a variety of relief, including (i) damages together with interest thereon and (ii) attorneys’ fees and costs of litigation. On October 14, 2014, Strathclyde Pension Fund was certified as lead plaintiff, and class counsel was appointed. On February 13, 2015, the defendants filed their motion to dismiss the complaint. On September 29, 2015, the District Court granted defendants’ motion to dismiss, but ruled that plaintiff could file an amended complaint. On November 6, 2015, plaintiff filed an amended complaint, and on January 13, 2016, the defendants filed their motion to dismiss this amended complaint. On September 23, 2016, the District Court granted in part and denied in part this motion to dismiss. The damages sought in this action have not yet been quantified. Pursuant to the Underwriting Agreement, dated May 22, 2013, entered into in connection with the IPO, the Company has agreed to reimburse the underwriters for the legal fees and other expenses reasonably incurred by the underwriters’ law firm in its representation of the underwriters in connection with this matter. Pursuant to Indemnification Agreements, dated as of May 22, 2013, between the Company and each of the directors and officers named in this action, the Company has agreed to assume the defense of such directors and officers. We believe the purported federal securities class action is without merit and will vigorously defend the lawsuit.

In Raul Carrillo-Hueso and Chec Xiong v. Ply Gem Industries, Inc. and Ply Gem Pacific Windows Corporation, a purported class action filed on November 25, 2015 in the Superior Court of the State of California, County of Alameda, plaintiffs, on behalf of themselves and all others similarly situated, allege damages as a result of, among other things, the defendants’ failure to provide (i) statutorily required meal breaks at the Sacramento, California facility, (ii) accurate wage statements to employees in California, and (iii) all wages due on termination in California. The plaintiffs seek a variety of relief, including (i) economic and compensatory damages, (ii) statutory damages, (iii) penalties, (iv) pre- and post-judgment interest, and (v) attorneys' fees and costs of litigation. The damages sought in this action have not yet been quantified.

In Tina Morgan v. Ply Gem Industries, Inc. and Simonton Industries, Inc., a purported class action filed on December 11, 2015 in the Superior Court of the State of California, County of Solano, plaintiff, on behalf of herself and all others similarly situated, alleges damages as a result of, among other things, the defendants’ failure at the Vacaville, California facility to (i) pay overtime wages, (ii) provide statutorily required meal breaks, (iii) provide accurate wage statements, and (iv) pay all wages owed upon termination. The plaintiff seeks a variety of relief, including (i) economic and compensatory damages, (ii) statutory damages, (iii) penalties, (iv) pre- and post-judgment interest, and (v) attorneys' fees and costs of litigation. The damages sought in this action have not yet been quantified.

In Kiefer et al. v. Simonton Building Products, LLC et al., a purported class action filed on October 17, 2016 in the United States District Court for the District of Minnesota, plaintiffs, on behalf of themselves and all others similarly situated, allege damages as a result of, among other things, the defective design and manufacture of certain Simonton windows containing two-pane insulating glass units. The plaintiffs seek a variety of relief, including (i) economic and compensatory damages, (ii) punitive or other exemplary damages, (iii) pre- and post-judgment interest, and (iv) attorneys' fees and costs of litigation. The damages sought in this action have not yet been quantified.

Other contingencies

The Company is subject to other contingencies, including legal proceedings and claims arising out of its operations and businesses that cover a wide range of matters, including, among others, environmental, contract, employment, intellectual property, securities, personal injury, property damage, product liability, warranty, and modification, adjustment or replacement of component parts or units sold, which may include product recalls.  Product liability, environmental and other legal proceedings also include matters with respect to businesses previously owned.  The Company has used various substances in their products and manufacturing operations, which have been or may be deemed to be hazardous or dangerous, and the extent of its potential liability, if any, under environmental, product liability and workers’ compensation statutes, rules, regulations and case law is unclear.  Further, due to the lack of adequate information and the potential impact of present regulations and any future regulations, there are certain circumstances in which no range of potential exposure may be reasonably estimated.  Also, it is not possible to ascertain the ultimate legal and financial liability with respect to certain contingent liabilities, including lawsuits, and therefore no such estimate has been made as of October 1, 2016.

Long-term incentive plan

The Company has a long-term incentive plan (“LTIP”) for certain employees. The long-term incentive plan was implemented to retain and incentivize key employees. During the three months ended October 1, 2016 and October 3, 2015, the Company recognized a LTIP expense of $1.4 million and $0.7 million, respectively, which has been recorded within selling, general, and administrative expenses in the condensed consolidated statements of operations and comprehensive income (loss). During the nine months ended October 1, 2016 and October 3, 2015, the Company recognized a LTIP expense of $4.9 million and $2.2 million, respectively, which has been recorded within selling, general, and administrative expenses in the condensed consolidated statements of operations and comprehensive income (loss). The LTIP liability was $7.6 million and $5.9 million as of October 1, 2016 and December 31, 2015, respectively, of which $5.1 million and $3.1 million has been recorded within accrued expenses and $2.5 million and $2.8 million in other long-term liabilities in the condensed consolidated balance sheets as of October 1, 2016 and December 31, 2015, respectively.

Other liabilities

During the nine months ended October 1, 2016 and October 3, 2015, the Company made approximately $0.6 million and $1.8 million, in cash payments on restructuring liabilities, respectively. These payments were for a restructuring and integration program implemented in Western Canada and general back office centralization efforts incurred as well as product simplification costs incurred for the entire Windows and Doors segment.

9.   INCOME TAXES

Effective tax rate

Under FASB Accounting Standards Codification 740-270, Income Taxes - Interim Reporting, each interim period is considered an integral part of the annual period and tax expense is measured using an estimated annual effective rate. Estimates of the annual effective tax rate at the end of interim periods are, of necessity, based on evaluation of possible future events and transactions and may be subject to subsequent refinement or revision. The Company calculates its quarterly tax provision consistent with the guidance provided by ASC 740-270, whereby the Company forecasts its estimated annual effective tax rate then applies that rate to its year-to-date pre-tax book income (loss). In addition, we exclude jurisdictions with a projected loss for the year or the year-to-date loss where we cannot recognize a tax benefit from our estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter, based upon the mix and timing of actual earnings versus annual projections. In addition to the tax resulting from applying the estimated annual effective tax rate to pre-tax income (loss), the Company includes certain items treated as discrete events to arrive at an estimated effective tax rate. Future changes in the forecasted annual income (loss) projections, tax rate changes, or discrete tax items could result in significant adjustments to quarterly income tax expense (benefit) in future periods in accordance with ASC 740-270.

For the nine months endedOctober 1, 2016, the Company's estimated annual effective income tax rate was approximately 3.8%, which varied from the statutory rate primarily due to state income tax expense, valuation allowances, and foreign income taxes. The effective tax rate including discrete items, primarily related to the valuation allowance release, was 240.3% for the nine months ended October 1, 2016. The tax benefit for the three months ended October 1, 2016 was approximately $49.1 million, and the tax expense for the three months ended October 3, 2015 was approximately $2.1 million. The tax benefit for the nine months ended October 1, 2016 was approximately $48.6 million, and the tax benefit for the nine months ended October 3, 2015 was approximately $1.8 million. The tax benefit increased during the three and nine months ended October 1, 2016 from the valuation allowance release for federal and certain state jurisdictions, partially offset by state income tax, remaining valuation allowances, and foreign income taxes.

Valuation allowance

During the three and nine months ended October 1, 2016, the Company determined that a valuation allowance was no longer required against its federal deferred tax assets and a portion of its state deferred tax assets. Therefore, the Company released approximately $50.1 million of its valuation allowance since positive evidence outweighed negative evidence thereby allowing the Company to achieve the “more likely than not” realization threshold. As of October 1, 2016, the Company was no longer in a three-year cumulative pre-tax loss position due to the significant improvement in the Company’s profitability from the housing market recovery. The housing market has experienced steady improvement from a demand perspective over the last several years which has benefited the Company’s financial performance and profitability for both new construction and repair and remodeling reflected in the Company’s net sales and earnings growth. This annual financial improvement was further evidenced by the Company continuing to have net sales and profitability growth in the Company’s second and third quarters which are traditionally the Company’s strongest financial quarters based on seasonality. Finally, the consensus expectation and outlook for both new construction and repair and remodeling both show positive growth rates over the next few years which result in future forecasted profitability for the Company. Based on the preponderance of these positive factors, the valuation allowance was released during the three and nine months ended October 1, 2016. The valuation allowance release is reflected within our provision (benefit) for income taxes in the accompanying condensed consolidated statement of operations and comprehensive income (loss) during the three and nine months ended October 1, 2016.

The Company determined that when a change in valuation allowance is recognized in an interim period, a portion of the valuation allowance to be released must be allocated to the remaining interim periods. Accordingly, a portion of the remaining valuation allowance, approximately $16.8 million, will release for the Company in the fourth quarter of 2016. The Company still remains in a valuation allowance position against its deferred tax assets for certain state and Canadian jurisdictions as it is currently deemed "more likely than not" that the benefit of such net tax assets will not be utilized as the Company continues to be in a three-year cumulative loss position for these states and Canadian jurisdictions. The Company will continue to monitor the positive and negative factors for these jurisdictions and make further changes to the valuation allowances as necessary.

Tax uncertainties

Despite the Company’s belief that its tax return positions are consistent with applicable tax laws, the Company believes that certain positions could be challenged by taxing authorities. The Company’s tax reserves reflect the difference between the tax benefit claimed on tax returns and the amount recognized in the condensed consolidated financial statements. These reserves have been established based on management’s assessment as to potential exposure attributable to permanent differences and interest and penalties applicable to both permanent and temporary differences. The tax reserves are reviewed periodically and adjusted in light of changing facts and circumstances, such as progress of tax audits, lapse of applicable statutes of limitations and changes in tax law. Certain income tax returns are currently under examination by various taxing authorities. During the nine months endedOctober 1, 2016, approximately $0.2 million of interest expense was recorded on the remaining uncertain tax positions. The Company made no other adjustments to the tax reserves or penalties during the nine months endedOctober 1, 2016.

The liability for unrecognized tax benefits as of October 1, 2016 was approximately $3.1 million and is recorded in other long-term liabilities in the accompanying condensed consolidated balance sheet. The corresponding amount of gross unrecognized tax benefit was approximately $15.9 million. The difference between the total unrecognized tax benefits and the amount of the liability for unrecognized tax benefits represents unrecognized tax benefits that have been netted against deferred tax assets related to net operating losses in accordance with ASC 740 in addition to accrued penalties and interest.

Tax Receivable Agreement

On May 22, 2013, the Company entered into a Tax Receivable Agreement (the “Tax Receivable Agreement”) with PG ITR Holdco, L.P. (the “Tax Receivable Entity”). The Tax Receivable Agreement generally provides for the payment by the Company to the Tax Receivable Entity of 85% of the amount of cash savings, if any, in U.S. federal, state and local income tax that the Company actually realizes in periods ending after the IPO as a result of (i) NOL carryovers from periods (or portions thereof) ending before January 1, 2013, (ii) deductible expenses attributable to the transactions related to the IPO and (iii) deductions related to imputed interest deemed to be paid by the Company as a result of or attributable to payments under the Tax Receivable Agreement. The term of the Tax Receivable Agreement will continue until all such benefits have been utilized or expired. The Company will retain the benefit of the remaining 15% of these tax savings. The Tax Receivable Agreement will obligate the Company to make payments to the Tax Receivable Entity generally equal to 85% of the applicable cash savings that is actually realized as a result of utilizing NOL carryovers once the tax returns are filed for that respective tax year.

The Company estimates that the total anticipated amount of future payments under the Tax Receivable Agreement could be up to approximately $89.0 million assuming no material changes in the relevant tax law, that the Company earns sufficient taxable income to utilize the net operating loss carry forwards, and that utilization of such tax attributes is not subject to limitation under Section 382 of the Internal Revenue Code of 1986, as amended (the "Code") as the result of an “ownership change”. It is possible that future transactions or events or changes in estimates could increase or decrease the actual tax benefits realized from these tax attributes and the corresponding Tax Receivable Agreement payments and liability.

Since the inception of the TRA liability with the Company’s 2013 initial public offering, the Company has had a full valuation allowance on its federal deferred tax assets and a partial valuation allowance on certain state and Canadian jurisdictions. As a result of the Company’s tax valuation allowance position for federal and state purposes, the Company calculated the TRA liability considering (i) current year taxable income only (due to the uncertainty of future taxable income associated with the Company’s cumulative loss position) and (ii) future income due to the expected reversals of deferred tax liabilities. During the three and nine months ended October 1, 2016, the Company released its valuation allowance on its federal deferred tax assets and certain state deferred tax assets for approximately $50.1 million due to positive factors outweighing negative evidence and specifically, the Company no longer being in a cumulative loss position. This release thereby eliminated any uncertainty as to future taxable income. Consequently, for purposes of calculating the Company’s TRA liability it was able to utilize future forecasts of taxable income beyond the 2016 tax year to determine the liability as of October 1, 2016. As a result of including future taxable income beyond 2016, the Company recognized a $42.2 million increase to the TRA liability during the three months ended October 1, 2016 bringing the total TRA liability to $84.4 million as of October 1, 2016. This amount represents the originally anticipated TRA liability at the initial public offering date with approximately $4.4 million remaining to be expensed through operations for state purposes as the Company remains in a tax valuation allowance position as of October 1, 2016 for certain states. This remaining liability will be recognized as the state valuation allowances are released in future years.

26

As of October 1, 2016 and December 31, 2015, the Company had a long-term liability of approximately $79.9 million and $20.8 million, respectively, and a current liability of $4.5 million and $3.0 million, respectively, for the amount due pursuant to the Tax Receivable Agreement. The Company recognized a $42.2 million expense and $1.7 million benefit for this liability during the three months ended October 1, 2016 and October 3, 2015, respectively. The Company recognized a $60.6 million and $13.5 million expense for this liability during the nine months ended October 1, 2016 and October 3, 2015, respectively.

Other

As of October 1, 2016, the Company has not established U.S. deferred taxes on unremitted earnings of the Company’s foreign subsidiaries. Notwithstanding the provisions within the American Jobs Creation Act of 2004, the Company continues to consider these amounts to be permanently reinvested.

Item 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The information contained in this discussion and in the unaudited condensed consolidated financial statements and accompanying notes presented in this Quarterly Report on Form 10-Q should be read in conjunction with information set forth in Ply Gem Holdings’ Annual Report on Form 10-K for the year ended December 31, 2015.  Certain statements in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations” are “forward-looking statements”.  See “Special Note Regarding Forward-Looking Statements.”  As used in this Quarterly Report on Form 10-Q, the “Company”, “we”, “us”, and “our” refer to Ply Gem Holdings and its subsidiaries, except where the context otherwise requires or as otherwise indicated.

Overview

We are a leading manufacturer of exterior building products in North America, operating in two reportable segments: (i) Siding, Fencing and Stone and (ii) Windows and Doors, which comprised approximately 49% and 51% of our net sales, respectively, for the three months ended October 1, 2016.  These two segments produce a comprehensive product line of vinyl siding, designer accents, cellular PVC trim, vinyl fencing, vinyl railing, stone veneer, roofing, and vinyl windows and doors used in both the new construction market and the home repair and remodeling market in the United States and Canada.  Vinyl building products have the leading share of sales volume in siding and windows in the United States.  We also manufacture vinyl and aluminum soffit and siding accessories, aluminum trim coil, wood windows, aluminum windows, vinyl and aluminum-clad windows and steel and fiberglass doors, enabling us to bundle complementary and color-matched products and accessories with our core products.  We believe that our comprehensive product portfolio and geographically diverse, low cost manufacturing platform allow us to better serve our customers and provide us with a competitive advantage over other exterior building products suppliers.  

Since we incorporated in 2004, we have acquired ten additional businesses to complement and expand our product portfolio and geographic diversity, including one acquisition during 2014 and one during 2015.  On September 19, 2014, we acquired all of the issued and outstanding shares of common stock of Fortune Brands Windows, Inc. ("Simonton"), a manufacturer of windows, for a purchase price of $130.0 million. On May 29, 2015, we acquired substantially all of the assets of Canyon Stone, Inc. (“Canyon Stone”), a manufacturer of stone veneer, for a purchase price of $21.0 million. Simonton is included in our Windows and Doors segment while Canyon Stone is included in our Siding, Fencing, and Stone segment.

Prior to January 11, 2010, Ply Gem Holdings was a wholly owned subsidiary of Ply Gem Investment Holdings, which was a wholly owned subsidiary of Ply Gem Prime.  On January 11, 2010, Ply Gem Investment Holdings merged with and into Ply Gem Prime, with Ply Gem Prime being the surviving corporation.  In May 2013, as part of the reorganization in connection with our initial public offering ("IPO"), Ply Gem Prime merged with and into us. The Company issued 18,157,895 shares of common stock at its IPO and received gross proceeds of approximately $381.3 million.

We are a holding company with no operations or assets of our own other than the capital stock of our subsidiaries. The terms of Ply Gem Industries' $350.0 million ABL Facility and the credit agreement governing the terms of its $430.0 million Term Loan Facility place restrictions on the ability of Ply Gem Industries and our other subsidiaries to pay dividends and otherwise transfer assets to us.  Further, the terms of the indenture governing Ply Gem Industries' $650.0 million 6.50% Senior Notes place restrictions on the ability of Ply Gem Industries and our other subsidiaries to pay dividends and otherwise transfer assets to us.

Financial statement presentation

Net Sales.  Net sales represent the fixed selling price of our products plus certain shipping charges less applicable provisions for discounts and allowances.  Allowances include cash discounts, volume rebates and returns.

Cost of products sold.  Cost of products sold includes direct material and manufacturing costs, manufacturing depreciation, third-party and in-house delivery costs and product warranty expense.

Selling, general and administrative expenses.  Selling, general and administrative expenses (“SG&A expense”) includes all non-product related operating expenses, including selling, marketing, research and development costs, information technology, and other general and administrative expenses.

36

Operating earnings (loss).  Operating earnings (loss) represents net sales less cost of products sold, SG&A expense and amortization of intangible assets.

Impact of commodity pricing

PVC resin and aluminum are major components in the production of our products and changes in PVC resin and aluminum prices have a direct impact on our cost of products sold.  Historically, we have been able to pass on a substantial portion of significant price increases to our customers.  The results of operations for individual quarters can be negatively impacted by a delay between the time of raw material cost increases and price increases that we implement in our products, or conversely can be positively impacted by a delay between the time of a raw material price decrease and competitive pricing moves that we implement accordingly.

Impact of weather

Since our building products are intended for exterior use, our sales and operating earnings tend to be lower during periods of inclement weather.  Weather conditions in the first and fourth quarters of each calendar year historically result in these quarters producing significantly less sales revenue than in any other period of the year.  As a result, we have historically had lower profits or higher losses in the first quarter, and reduced profits in the fourth quarter of each calendar year due to the weather.  Our results of operations for individual quarters in the future may be impacted by adverse weather conditions. In addition, favorable or unfavorable weather conditions may influence the comparability of our results from year to year or from quarter to quarter.

Critical Accounting Policies

Our discussion and analysis of financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States, or GAAP.  The preparation of our financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent liabilities.  We base these estimates on our historical experience and on various other assumptions that we believe to be reasonable under the circumstances, and these estimates form the basis for our judgments concerning the carrying values of assets and liabilities that are not readily apparent from other sources.  By their nature, these estimates and judgments are subject to an inherent degree of uncertainty.  We periodically evaluate these estimates and judgments based on available information and experience.  Actual results could differ from our estimates under different assumptions and conditions.  If actual results significantly differ from our estimates, our financial condition and results of operations could be materially impacted.  For more information regarding our critical accounting policies and estimates please refer to Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies contained in our Annual Report on Form 10-K for the year ended December 31, 2015 and Note 1 to our consolidated financial statements. There have been no material changes to the critical accounting policies previously disclosed in that report.

Results of Operations

The following table summarizes net sales and operating earnings (loss) by segment and is derived from the accompanying condensed consolidated statements of operations and comprehensive income (loss) included in this report.

This review of performance is organized by business segment, reflecting the way we manage our business.  Each business group leader is responsible for operating results down to operating earnings.  We use operating earnings as a performance measure as it captures the income and expenses within the management control of our business leaders.  Corporate management is responsible for making all financing decisions.  Therefore, each segment discussion focuses on the factors affecting operating earnings, while interest expense and income taxes and certain other unallocated expenses are separately discussed at the corporate level.

The following tables set forth our results of operations based on the amounts and the percentage relationship of the items listed to net sales for the periods indicated.  However, our results of operations set forth in the tables below may not necessarily be representative of our future operating results.

Net Sales

Net sales for the three months ended October 1, 2016 increased $3.9 million or 1.5% as compared to the three months ended October 3, 2015. The 1.5% net sales increase was driven by a $4.9 million net sales increase or 2.2% in the U.S. market partially offset by a net sales decrease of $1.0 million or 3.0% in Canada. In the U.S. market, the 2.2% net sales increase for the three months ended October 1, 2016 resulted from improved U.S. market demand for our products and new business wins. We achieved increased unit sales of approximately 6.8% from this demand increase partially offset by lower average selling prices of approximately 4.4% that were reduced in response to lower material costs during the three months ended October 1, 2016 as compared to the three months ended October 3, 2015. The lower average selling prices for our products negatively impacted our net sales by approximately $8.9 million during the three months ended October 1, 2016 as compared to the three months ended October 3, 2015. The positive demand factors in the U.S. market were partially offset by continued weaker market demand in Canada which, when combined with $0.2 million of negative foreign currency attributed to our Canadian net sales, caused the Canadian $1.0 million net sales decrease. Market demand in Canada has been negatively impacted by the 2016 decline in energy prices, particularly in Western Canada, where housing starts have declined significantly in Alberta.

Our building products are typically installed on a new construction home 90 to 120 days after the start of the home, therefore, single family housing starts commencing in the period from April 2016 to June 2016 directly impacts the demand for our products in the three months ended October 1, 2016. According to the U.S. Census Bureau, single family housing starts increased 9.0% during this lag affected time period reflecting improved market conditions. In addition to the new construction market improvement, remodeling activity, according to the Leading Indicator of Remodeling Activity (“LIRA”), reflected the 2016 third quarter trailing twelve months increasing 6.6% compared to the prior year period. Our Siding, Fencing and Stone segment is heavily weighted to the repair and remodeling market. Our unit sales increase of 6.8% in the U.S. and decrease of 5.9% in Canada for the three months ended October 1, 2016 reflect the broader market indicators but exceeded the overall vinyl siding industry which according to the Vinyl Siding Institute reported increased U.S. shipments of 4.2%, while Canada decreased 10.8%.

39

The improved U.S. market conditions drove our net sales increase during the three months ended October 1, 2016; however, our sales also benefited from new business wins which is demonstrated by maintaining our leading U.S. vinyl siding market position at 38.9% for the three months ended October 1, 2016 and October 3, 2015, while our share of the Canadian vinyl siding market improved from 32.5% to 34.3% for the comparable three month period. For the three months ended October 1, 2016 and October 3, 2015, the percentage of net sales in vinyl siding and metal accessories represented approximately 59.4% and 23.3% and 59.5% and 24.4%, respectively, with our net sales of other products comprising approximately 17.3% and 16.1%.

Gross Profit

Gross profit for the three months ended October 1, 2016 increased $3.4 million or 4.4% as compared to the three months ended October 3, 2015. The gross profit increase for the three months ended October 1, 2016 resulted from the 1.5% net sales increase generated from improved U.S. market demand for our products and new business wins. The higher sales volumes experienced during the three months ended October 1, 2016 in the U.S. enabled us to increase our operating leverage relative to the three months ended October 3, 2015. In addition, we continued to experience favorable material cost pricing during the three months ended October 1, 2016 relative to the three months ended October 3, 2015, specifically for PVC resin and aluminum as a result of strategic purchases we made throughout the period. This favorable material cost pricing increased gross profit by approximately $9.2 million during the three months ended October 1, 2016 relative to the three months ended October 3, 2015. However, the favorable material cost pricing, was largely offset by lower average selling prices for the three months ended October 1, 2016 as compared to the three months ended October 3, 2015 of approximately 4.4%. In addition, our Canadian gross profit declined 10.8% or $1.1 million during the three months ended October 1, 2016 relative to the three months ended October 3, 2015 based on the declining Canadian economic conditions prevalent in Western Canada which are heavily dependent on energy prices to sustain their economy.

As a percentage of net sales, gross profit increased from 30.3% for the three months ended October 3, 2015 to 31.2% for the three months ended October 1, 2016. The 90 basis point improvement for the three months ended October 1, 2016 resulted predominantly from improved operating leverage from higher U.S. unit volume sales partially offset by weakening demand in Canada. Our Canadian business experienced a 260 basis point decrease in gross profit percentage from reduced leverage associated with lower unit volume sales, unfavorable material costs associated with foreign currency movements, and unfavorable product mix.

Selling, general and administrative expenses

SG&A expense for the three months ended October 1, 2016 decreased a nominal $0.4 million or 1.6% compared to the three months ended October 3, 2015. As a percentage of net sales, SG&A expense decreased 30 basis points from 9.0% for the three months ended October 3, 2015 to 8.7% for the three months ended October 1, 2016 as a result of improved leverage on the fixed component of our SG&A expense.

Amortization of intangible assets

Amortization expense for the three months ended October 1, 2016 remained consistent with the three months ended October 3, 2015 at approximately $3.3 million each period. In addition, as a percentage of net sales, amortization expense remained consistent at 1.3% for the three months ended October 1, 2016 and October 3, 2015.

Currency transaction gain (loss)

The currency transaction gain for the three months ended October 1, 2016 was $0.1 million resulting from the impact of the Canadian dollar fluctuation. The currency transaction loss for the three months ended October 3, 2015 was a nominal $0.5 million resulting from the fluctuation in the Canadian dollar during the period.

Net Sales

Net sales for the nine months ended October 1, 2016 increased $29.6 million or 4.6% as compared to the nine months ended October 3, 2015. The 4.6% net sales increase resulted from a $34.3 million net sales increase or 6.1% in the U.S. market partially offset by a net sales decrease of $4.7 million or 5.5% for Canada. In the U.S. market, the 6.1% net sales increase for the nine months ended October 1, 2016 was driven by improved U.S. market demand for our products, new business wins, and $11.7 million of net sales attributed to our Canyon Stone acquisition, which was completed on May 29, 2015. Excluding Canyon Stone, our net sales in the U.S. market would have increased 4.0% for the nine months ended October 1, 2016 compared to the nine months ended October 3, 2015. Our net sales growth in the U.S. market resulted from increased unit sales of approximately 10.1% partially offset by lower average selling prices of approximately 4.9% that were reduced in response to lower raw material input costs during the nine months ended October 1, 2016 as compared to the nine months ended October 3, 2015. The lower average selling prices for our products negatively impacted our net sales by approximately $29.5 million during the nine months ended October 1, 2016 as compared to the nine months ended October 3, 2015. In addition, our net sales for the nine months ended October 1, 2016 were negatively impacted by $2.2 million having one less shipping day based on the timing of our fiscal calendar. The positive demand factors in the U.S. market were partially offset by continued weaker market demand in Canada which when combined with $3.9 million of negative foreign currency resulted in the $4.7 million Canadian net sales decrease. Market demand in Canada has been negatively impacted by the 2016 decline in energy prices, particularly in Western Canada, where housing starts have declined significantly in Alberta (31.0%).

Our building products are typically installed on a new construction home 90 to 120 days after the start of the home, therefore, single family housing starts commencing in the period from September 2015 to June 2016 directly impacts the demand for our products in the nine months ended October 1, 2016. According to the U.S. Census Bureau, single family housing starts increased 12.2% during this lag affected time period reflecting improved market conditions. In addition to the new construction market improvement, remodeling activity, according to LIRA, reflected the 2016 third quarter trailing twelve months increasing 6.6% compared to the prior year period. Since our segment is heavily weighted to the repair and remodeling market, we estimate the weighted average U.S. market increase was 8.5% for the nine months ended October 1, 2016. Our U.S. unit sales increase of 10.1% outperformed the estimated market increase but was partially offset by lower average selling prices which lowered net sales by $29.5 million. The improvement in single family housing starts and remodeling expenditures as well as our ability to exceed these market indicators on a unit basis is evidenced by the Vinyl Siding Institute reporting that U.S. vinyl siding industry shipments increased 6.9% while shipments in Canada decreased 9.5% for the first nine months of 2016 relative to the same period in 2015 compared to our vinyl industry shipments increase of 8.9% in the U.S. and our 4.2% decrease in Canada.

The improved U.S. market conditions drove our 4.0% net sales increase during the nine months ended October 1, 2016, however our sales also benefited from new business wins which we believe is demonstrated by the improvement in our U.S. market position in vinyl siding which increased from 38.5% to 39.2% for the comparable nine month period, while our share of the Canadian vinyl siding market improved from 29.8% to 31.6% for the comparable nine month period.

For the nine months ended October 1, 2016 and October 3, 2015, the percentage of net sales in vinyl siding and metal accessories represented approximately 58.4% and 24.3% and 60.7% and 24.4%, respectively, with our net sales of other products comprising approximately 17.3% and 14.9%. The net sales decrease in vinyl siding on a percentage basis was due in part to a sales increase of our manufactured stone product as a result of our Canyon Stone acquisition which was completed on May 29, 2015.

Gross Profit

41

Gross profit for the nine months ended October 1, 2016 increased $21.9 million or 12.0% as compared to the nine months ended October 3, 2015. The gross profit increase for the nine months ended October 1, 2016 resulted from the 4.6% net sales increase and included approximately $3.4 million of gross profit from our Canyon Stone acquisition, which was completed on May 29, 2015. Excluding Canyon Stone, our gross profit increase would have been $18.5 million or 10.1% for the nine months ended October 1, 2016 as compared to the nine months ended October 3, 2015. The higher sales volumes experienced during the nine months ended October 1, 2016 in the U.S. enabled us to increase our operating leverage relative to the nine months ended October 3, 2015. In addition, we experienced favorable material cost pricing during the nine months ended October 1, 2016 relative to the nine months ended October 3, 2015 specifically for PVC resin and aluminum. The favorable net material cost pricing increased gross profit by approximately $34.5 million during the nine months ended October 1, 2016 relative to the nine months ended October 3, 2015. As a result of this favorable material cost pricing, we did experience lower average selling prices for the nine months ended October 1, 2016 as compared to the nine months ended October 3, 2015 of approximately 4.9% which partially offset the favorable material costing impact on gross profit. In addition, our Canadian gross profit declined 17.2% or $4.5 million during the nine months ended October 1, 2016 relative to the nine months ended October 3, 2015 as a result of unfavorable foreign currency impact of $2.7 million, as well as the declining Canadian economic conditions prevalent in Western Canada which are heavily dependent on energy prices to sustain their economy partially offset by favorable material costing of $0.7 million.

As a percentage of net sales, gross profit increased from 28.1% for the nine months ended October 3, 2015 to 30.1% for the nine months ended October 1, 2016 excluding the impact of the Canyon Stone acquisition. The 200 basis point increase for the nine months ended October 1, 2016 resulted from improved operating leverage from the 4.6% net sales increase as well as favorable material cost pricing and freight expense partially offset by lower average sales prices, an unfavorable foreign currency impact from a weakening Canadian dollar as well as weakening demand in Canada related to a slowdown in the Canadian economy.

Selling, general and administrative expenses

SG&A expense for the nine months ended October 1, 2016 increased $1.1 million or 1.6% as compared to the nine months ended October 3, 2015. Excluding the impact of the Canyon Stone acquisition which was completed on May 29, 2015 and incurred SG&A expense of approximately $2.6 million, SG&A expense decreased $1.5 million or 2.3%.

As a percentage of net sales excluding Canyon Stone, SG&A expense decreased from 10.3% for the nine months ended October 3, 2015 to 9.8% for the nine months ended October 1, 2016. The decrease reflects improved leverage on the fixed component of our SG&A expenses relative to the net sales increase with our sales and marketing expenses decreasing $2.5 million or 6.2% during the nine months ended October 1, 2016 compared to the nine months ended October 3, 2015.

Amortization of intangible assets

Amortization expense for the nine months ended October 1, 2016 increased $0.4 million or 4.4% compared to the nine months ended October 3, 2015. The $0.4 million increase can be attributed to the Canyon Stone acquisition which was completed on May 29, 2015 and incurred amortization expense of $0.6 million. Excluding Canyon Stone, amortization expense would have decreased $0.1 million or a nominal 1.4%.

As a percentage of net sales excluding the impact of Canyon Stone, amortization expense as a percentage of net sales was consistent at 1.4% for the nine months ended October 1, 2016 and 1.5% for the nine months ended October 3, 2015.

Currency transaction gain (loss)

The currency transaction gain for the nine months ended October 1, 2016 was $0.3 million resulting from the impact of the Canadian dollar fluctuation. The currency transaction loss for the nine months ended October 3, 2015 was $0.8 million resulting from the fluctuation in the Canadian dollar during the period.

Net Sales

Net sales for the three months ended October 1, 2016 decreased $4.3 million or 1.6% as compared to the three months ended October 3, 2015. The net sales decrease for the three months ended October 1, 2016 can be predominantly attributed to our sales performance in Canada where net sales decreased $3.4 million or 11.6% during the three months ended October 1, 2016 as compared to the three months ended October 3, 2015. Market demand in Canada has been negatively impacted by the 2016 decline in energy prices, particularly in Western Canada, where housing starts have significantly declined, particularly in Alberta. These economic conditions have negatively impacted demand leading to a 17.4% decrease in Canadian window units or $4.7 million in net sales. These net sales decreases were partially offset by achieving higher average selling prices of 4.3% for the three months ended October 1, 2016 compared to the three months ended October 3, 2015 increasing net sales by approximately $1.5 million. In addition to the overall Canadian demand environment, net sales were negatively impacted $0.2 million for the three months ended October 1, 2016 due to negative foreign currency impact.

In the U.S. market, our new construction business achieved a net sales increase of $1.5 million or 0.9% while our repair and remodeling business incurred a net sales decline of $2.4 million or 2.8%. The U.S. Census Bureau summarized U.S. market conditions stating that single family housing starts increased 9.0% during the lag effected period. Our building products are typically installed on a new construction home 90 to 120 days after the start of the home, therefore single family starts commencing in the period from April 2016 to June 2016 directly impacts the demand for our products in the three months ended October 1, 2016. Due to the favorable weather conditions that existed in the first quarter of 2016, we believe that net sales were pulled forward into the first quarter where our new construction business experienced a net sales increase of 14.5% versus the previous lag effected stated single family housing start increase of 7.8% for the first quarter. This net sales pull forward negatively impacted our net sales for the second and third quarters relative to market conditions. For the repair and remodeling business, LIRA reported that the 2016 third quarter trailing twelve months increased 6.6% compared to the prior year period creating a favorable demand environment. Our net sales for repair and remodeling lagged this LIRA market indicator for the three months ended October 1, 2016 reflecting the net sales pull forward impact into the first quarter in which our repair and remodeling sales increased $3.5 million or 5.6%.

Despite these lower net sales amounts relative to market indicators for the three months ended October 1, 2016 for new construction and repair and remodeling, we achieved higher average selling prices of 3.6% for the three months ended October 1, 2016 relative to the three months ended October 3, 2015. These higher selling prices increased our net sales by approximately $7.5 million for the three months ended October 1, 2016 compared to the three months ended October 3, 2015. These net sales increases were offset by lower sales in certain geographical areas, namely Texas and specifically Houston, due to extraordinarily high levels of rainfall which negatively impacted the construction industry and generally slower economic conditions related to the oil and gas industry. These factors contributed to our window sales in the Houston market decreasing 22.5%, while the broader Texas market decreased 7.6%. The negative market factors for Houston and Texas caused a net sales decline of $3.3 million for the three months ended October 1, 2016 compared to the three months ended October 3, 2015.

Gross Profit

Gross profit for the three months ended October 1, 2016 decreased $1.4 million or 2.4% as compared to the three months ended October 3, 2015. The gross profit decrease for the three months ended October 1, 2016 can be attributed to the overall net sales decrease of 1.6% for the period and unfavorable foreign currency impact of $1.2 million. Although we incurred higher costs in our U.S. new construction window business related to increased labor and freight, these higher costs were offset by improved average selling prices in the U.S. of 3.6% and 4.3% in Canada, favorable product mix and material cost pricing as well as cost savings and synergies that we realized from our Simonton acquisition.

43

As a percentage of net sales, gross profit experienced a nominal decrease from 20.8% for the three months ended October 3, 2015 to 20.6% for the three months ended October 1, 2016. The 20 basis point margin decrease reflects lower operating leverage and the unfavorable labor and freight cost in our U.S. new construction business partially offset by improved selling prices for our U.S. and Canadian window businesses.

Selling, general and administrative expenses

SG&A expense for the three months ended October 1, 2016 decreased $1.5 million or 4.1% as compared to the three months ended October 3, 2015. The decrease in SG&A expenses is primarily attributed to lower management incentive compensation expense partially offset by unfavorable legal expenses associated with the resolution of class action litigation for our new construction window business during the three months ended October 3, 2015.

As a percentage of net sales, SG&A expense decreased from 12.9% for the three months ended October 3, 2015 to 12.5% for the three months ended October 1, 2016. The 40 basis point decrease resulted from lower management incentive compensation expenses partially offset by increased legal expenses.

Amortization of intangible assets

Amortization expense for the three months ended October 1, 2016 remained consistent at $3.1 million and 1.1% of net sales with the three months ended October 3, 2015.

Currency transaction loss

The currency transaction loss for the three months ended October 1, 2016 was $0.2 million resulting from the impact of the Canadian dollar fluctuation. The currency transaction loss for the three months ended October 3, 2015 was $0.5 million resulting from the fluctuation in the Canadian dollar during the period.

Net Sales

Net sales for the nine months ended October 1, 2016 increased $10.7 million or 1.4% as compared to the nine months ended October 3, 2015. The net sales increase for the nine months ended October 1, 2016 can be attributed to the improved U.S. market conditions favorably impacting both our new construction business as well as our repair and remodeling business. For the nine months ended October 1, 2016 compared to the nine months ended October 3, 2015, our new construction business increased $27.1 million or 6.1% while our repair and remodeling business increased $4.1 million or 1.8%. This U.S. net sales increase was partially offset by a $20.5 million net sales decline or 22.9% of our Canadian net sales for the nine months ended October 1, 2016 compared to the nine months ended October 3, 2015 due to a weakening Canadian market.

44

The net sales increase for the U.S. market can be attributed to improved market conditions as evidenced by the U.S. Census Bureau stating that single family housing starts increased 12.2% during the lag effected period which resulted in higher net sales for our new construction products. Our building products are typically installed on a new construction home 90 to 120 days after the start of the home, therefore single family starts commencing in the period from September 2015 to June 2016 directly impacts the demand for our products in the nine months ended October 1, 2016. For the repair and remodeling business, LIRA reported that the 2016 third quarter trailing twelve months increased 6.6% compared to the prior year period creating a favorable demand environment. Our net sales for new construction and repair and remodeling were lower than the demand market indicators for the nine months ended October 1, 2016 due primarily to lower sales in certain geographical areas, namely Texas, specifically Houston, due to extraordinary high levels of rainfall which negatively impacted the construction industry and economic conditions in the Houston market related to the oil and gas industry. Our net sales of window products in the Houston market declined $7.1 million during the nine months ended October 1, 2016 compared to the nine months ended October 3, 2015. Our net sales for the nine months ended October 1, 2016 were also negatively impacted by $3.3 million having one less shipping day based on the timing of our fiscal calendar.

In addition to these improved demand market conditions for new construction and repair and remodeling, we experienced higher average selling prices of 4.0% for the nine months ended October 1, 2016 relative to the nine months ended October 3, 2015. These higher average selling prices increased our U.S. net sales by approximately $22.4 million for the nine months ended October 1, 2016 compared to the nine months ended October 3, 2015. The overall U.S. net sales increase of $31.2 million was partially offset by a $20.5 million net sales decline for our Western Canadian business which endured challenging market conditions negatively impacted by demand softness due to declining energy prices as well as a negative foreign currency impact of $3.5 million.

Gross Profit

Gross profit for the nine months ended October 1, 2016 increased $17.1 million or 12.5% as compared to the nine months ended October 3, 2015. The gross profit increase for the nine months ended October 1, 2016 can be attributed to the continued improvement in our new construction and repair and remodeling businesses partially offset by the negative impact from lower sales in Canada. Gross profit for our U.S. new construction and repair and remodeling business increased $12.3 million and $8.0 million, respectively, during the nine months ended October 1, 2016 compared to the nine months ended October 3, 2015. The gross profit improvement for our U.S. businesses was driven by increased selling prices of 4.0%, favorable product mix and lower raw material costs and cost savings and synergies that were realized from our Simonton acquisition. These favorable factors were partially offset by higher costs in our U.S. new construction window business related to labor and freight. These overall net gross profit improvements in the U.S. were partially offset by a gross profit decrease of $3.2 million for our Western Canadian business which experienced weaker market demand due to depressed economic conditions including a negative foreign currency impact of $2.5 million during the nine months ended October 1, 2016 compared to the nine months ended October 3, 2015.

As a percentage of net sales, gross profit increased from 18.0% for the nine months ended October 3, 2015 to 20.0% for the nine months ended October 1, 2016. The 200 basis point increase in gross profit reflects improvements for both our U.S. new construction and repair and remodeling window products from improved demand levels, higher average selling prices, and favorable material costs partially offset by a decrease for our Canadian business driven by the 22.9% net sales decrease which decreased operating leverage during the nine months ended October 1, 2016 as compared to the nine months ended October 3, 2015.

Selling, general and administrative expenses

SG&A expense for the nine months ended October 1, 2016 decreased $6.6 million or 5.7% as compared to the nine months ended October 3, 2015. The decrease in SG&A expense was attributable primarily to 2015 activity for acquisition integration and restructuring activities related to our repair and remodeling window acquisition which originally occurred in September 2014 as well as combining our Canadian window manufacturing facilities into a single facility. Specifically, our U.S. window repair and remodeling business incurred lower severance expenses of $1.3 million during the nine months ended October 1, 2016 compared to the nine months ended October 3, 2015. In addition, our U.S. window businesses incurred a combined $4.1 million in lower management incentive compensation, bad debt and marketing related expenses during the nine months ended October 1, 2016 compared to the nine months ended October 3, 2015. These expense decreases were partially offset by increased legal expense associated with the 2015 resolution of class action litigation for our new construction business of $3.2 million. For our Canadian window business, we experienced lower restructuring and integration charges of $2.3 million, as well as lower personnel costs of $1.7 million during the nine months ended October 1, 2016 compared to the nine months ended October 3, 2015 due to integration activities that occurred during 2015 finalizing our combination of our Western Canadian manufacturing facilities into a single location in Alberta.

45

As a percentage of net sales, SG&A expense decreased from 15.2% for the nine months ended October 3, 2015 to 14.2% for the nine months ended October 1, 2016. The 100 basis point decrease resulted from lower severance expense for our U.S. repair and remodeling window business, lower management compensation, lower selling and marketing expenses partially offset by increased legal expenses for the nine months ended October 1, 2016 compared to the nine months ended October 3, 2015. In addition, our Canadian window business incurred lower restructuring and personnel expenses during the nine months ended October 1, 2016 compared to the nine months ended October 3, 2015 from integration activities that were incurred during 2015 finalizing our combination our manufacturing operations into a single location in Alberta.

Amortization of intangible assets

Amortization expense for the nine months ended October 1, 2016 remained consistent at $9.3 million and 1.2% of net sales compared to the nine months ended October 3, 2015 of $9.3 million and 1.2% of net sales.

Currency transaction gain (loss)

The currency transaction gain for the nine months ended October 1, 2016 was $0.5 million resulting from the impact of the Canadian dollar fluctuation. The currency transaction loss for the nine months ended October 3, 2015 was $1.3 million resulting from the fluctuation in the Canadian dollar during the period.

Combined quarterly profitability and seasonality trend

Our consolidated gross profit margin increased from 25.4% for the three months ended October 3, 2015 to 25.8% for the three months ended October 1, 2016. This gross profit increase was primarily attributed to our improvement within the Siding, Fencing, and Stone segment which experienced an increase of $3.4 million or 4.4% as compared to the three months ended October 3, 2015. The gross profit increase for the three months ended October 1, 2016 resulted from a 1.5% net sales increase generated from improved U.S. market demand for our products and new business wins. The higher U.S. sales volumes experienced during the three months ended October 1, 2016 enabled us to increase our operating leverage relative to the three months ended October 3, 2015. In addition, we continued to experience favorable material cost pricing during the three months ended October 1, 2016 relative to the three months ended October 3, 2015 specifically for PVC resin and aluminum based on strategic purchases throughout the quarter. This favorable net material cost pricing increased gross profit by approximately $9.2 million during the three months ended October 1, 2016 relative to the three months ended October 3, 2015. As a result of this favorable material cost pricing, we experienced lower average selling prices for the three months ended October 1, 2016 as compared to the three months ended October 3, 2015 of approximately 4.4% which partially offset the favorable material costing impact on gross profit. This increase was partially offset by our Canadian gross profit within the Siding, Fencing, and Stone segment which declined 10.8% or $1.1 million during the three months ended October 1, 2016 relative to the three months ended October 3, 2015 based on the declining Canadian economic conditions prevalent in Western Canada which are heavily dependent on energy prices to sustain their economy. In addition to the Canadian decrease, our Windows and Doors segment incurred a gross profit decrease of $1.4 million or 2.4% during the three months ended October 1, 2016. This gross profit decrease can be attributed to the overall net sales decrease of 1.6% for the Windows and Doors segment as well as increased labor and freight expense in our new construction window business.

SG&A expense as a percentage of net sales was 11.8% for the three months ended October 1, 2016 as compared to 12.5% for the three months ended October 3, 2015. The decrease in SG&A expenses as a percentage of net sales can be attributed to lower management incentive compensation and marketing related expenses.

Overall, our key performance metrics and trends have improved relative to the prior year comparable period and to our first quarter which is typically our lower performing quarter due to seasonality. The positive trend in our 2016 operating performance continued during the three months ended October 1, 2016 with continued gross profit margin expansion from improved market conditions, improved average selling prices in our Windows and Doors segment, improved product mix, favorable materials costs partially offset by poor economic conditions for our Western Canadian business and the negative foreign currency impact for our Canadian business.

Operating loss

Unallocated losses include items which are not directly attributed to or allocated to either of our reporting segments.  Such items include legal costs, corporate payroll, and unallocated finance and accounting expenses.  The unallocated operating loss for the three months ended October 1, 2016 decreased by $2.2 million or 27.3% compared to the same period in 2015 due primarily to decreased stock compensation of $0.3 million, decreased health insurance expenses of $0.7 million and decreased other general professional expenses of $1.2 million.

Interest expense

Interest expense for the three months ended October 1, 2016 decreased by approximately $1.0 million or 5.4% compared to the same period in 2015 as a result of the reduction in the Term Loan Facility principal balance period over period. During March and August 2016, we made two separate $30.0 million voluntary payments on the Term Loan Facility in addition to our normal quarterly amortization payments of $1.1 million, or $4.3 million annually, which reduced our outstanding borrowings and our quarterly interest expense.

Tax receivable agreement ("TRA") liability adjustment

Since the inception of the TRA liability with the Company’s 2013 initial public offering, we have been in a full valuation allowance for federal purposes and a partial valuation allowance for certain state and Canadian jurisdictions. As a result of the Company’s tax valuation allowance position for federal and state purposes, we calculated the TRA liability considering (i) current year taxable income only (due to the uncertainty of future taxable income associated with our cumulative loss position) and (ii) future income due to the expected reversals of deferred tax liabilities. During the three months ended October 1, 2016, we released our federal valuation allowance and a portion of our state valuation allowance for $50.1 million due to positive factors outweighing negative evidence, specifically no longer being in a cumulative loss position. This release thereby eliminated any uncertainty as to future taxable income. Consequently, we were able to utilize future forecasts of taxable income beyond the 2016 tax year to determine the TRA liability as of October 1, 2016. Our future taxable income estimates were used to determine the cumulative NOLs that are expected to be utilized and the TRA liability was accordingly adjusted using the 85% TRA rate. As a result of including future taxable income beyond 2016, we recognized a $42.2 million increase to the TRA liability during the three months ended October 1, 2016 bringing the total TRA liability to $84.4 million as of October 1, 2016. This amount represents the originally anticipated TRA liability at the initial public offering date with approximately $4.4 million remaining to be expensed through operations for state purposes as we remain in a state tax valuation allowance position as of October 1, 2016 for certain states. This remaining liability will be recognized as the state valuation allowances are released in future years.

Loss on modification or extinguishment of debt

During August 2016, we voluntarily paid $30.0 million on the Term Loan Facility to reduce our outstanding indebtedness as allowable under the terms of the agreement governing the Term Loan Facility. We performed an analysis to determine the proper accounting treatment for this voluntary payment by evaluating the change in cash flows and determining that there were no changes in the creditors as a result of the payment. Consequently, we recognized a loss on debt modification or extinguishment of approximately $2.3 million for the three months ended October 1, 2016 consisting of the proportionate write off of the related debt issuance costs and debt discount.

47

Income taxes

Our pre-tax income for the three months ended October 1, 2016 was approximately $5.6 million including the $42.2 million tax receivable agreement liability adjustment compared to pre-tax income of $43.8 million including the $1.7 million tax receivable agreement liability adjustment for the three months ended October 3, 2015. The income tax benefit for the three months ended October 1, 2016 increased by $51.2 million compared to the same period in 2015 due primarily to the reversal of the valuation allowance on the federal deferred tax assets and the partial reversal of the valuation allowances on certain state jurisdictions of $50.1 million partially offset by state income taxes, remaining valuation allowances, and foreign income tax. We released the federal and certain state valuation allowances as positive factors outweighed negative evidence, specifically no longer being in a cumulative loss position. As of October 1, 2016, we still remain in a valuation allowance position for certain state and Canadian jurisdictions.

Operating loss

Unallocated losses include items which are not directly attributed to or allocated to either of our reporting segments.  Such items include legal costs, corporate payroll, and unallocated finance and accounting expenses.  The unallocated operating loss for the nine months ended October 1, 2016 decreased by $2.0 million or 8.3% compared to the same period in 2015 due primarily to decreased audit fee expenses of $0.5 million, decreased health insurance expenses of $0.7 million, decreased other general professional expenses of $2.5 million, decreased legal fee expense of $0.5 million, and decreased stock compensation of $0.8 million, partially offset by increased incentive compensation of $3.0 million.

Interest expense

Interest expense for the nine months ended October 1, 2016 decreased by approximately $1.6 million or 2.8% compared to the same period in 2015 as a result of the reduction in the Term Loan Facility principal balance period over period and lower average borrowings on the ABL Facility period over period. During both March and August 2016, we made $30.0 million voluntary payments on the Term Loan Facility in addition to our normal quarterly amortization payments of $1.1 million, or $4.3 million annually, which reduced our outstanding borrowings and our quarterly interest expense.

TRA liability adjustment

48

Since the inception of the TRA liability with the Company’s 2013 initial public offering, we have been in a full valuation allowance for federal purposes and a partial valuation allowance for certain state and Canadian jurisdictions. As a result of the Company’s tax valuation allowance position for federal and state purposes, we calculated the TRA liability considering (i) current year taxable income only (due to the uncertainty of future taxable income associated with our cumulative loss position) and (ii) future income due to the expected reversals of deferred tax liabilities. During the nine months ended October 1, 2016, we released our federal valuation allowance and a portion of our state valuation allowance for $50.1 million due to positive factors outweighing negative evidence, specifically no longer being in a cumulative loss position. This release thereby eliminated any uncertainty as to future taxable income. Consequently, we were able to utilize future forecasts of taxable income beyond the 2016 tax year to determine the TRA liability as of October 1, 2016. Our future taxable income estimates were used to determine the cumulative net operating loss carryforwards ("NOLs") that are expected to be utilized and the TRA liability was accordingly adjusted using the 85% TRA rate. As a result of including future taxable income beyond 2016, we recognized a $60.6 million adjustment to the TRA liability during the nine months ended October 1, 2016 bringing the total TRA liability to $84.4 million as of October 1, 2016. This amount represents the originally anticipated TRA liability at the initial public offering date with approximately $4.4 million remaining to be expensed through operations for state purposes as we remain in a state tax valuation allowance position as of October 1, 2016 for certain states. This remaining liability will be recognized as the state valuation allowances are released in future years.

The $47.1 million increase for the TRA liability adjustment for the nine months ended October 1, 2016 relative to the nine months ended October 3, 2015 resulted primarily from the valuation allowance release as well as increases in taxable income estimates. The increase in the 2016 estimated taxable income resulted from the industry increasing their projections of single family housing starts (“SFHS”) for 2016 by 11.0% compared to 2015 actual SFHS of 714 which increased our forecasts and estimates for 2016 taxable income. Furthermore, we have estimated an increase in repair and remodeling which also increased our forecasts and estimates for 2016 taxable income. All of these factors increased our 2016 taxable income estimate and therefore increased the TRA liability in addition to the inclusion of taxable income for years after 2016 as a result of the release of the valuation allowance during the nine months ended October 1, 2016.

Loss on modification or extinguishment of debt

During both March and August 2016, we voluntarily paid $30.0 million on the Term Loan Facility to reduce our outstanding indebtedness as allowable under the terms of the Term Loan Facility by a total of $60.0 million during 2016. We performed an analysis on both of these transactions to determine the proper accounting treatment for these voluntary payments by evaluating the change in cash flows and determining that there were no changes in the creditors as a result of the payment. Consequently, we recognized a loss on debt modification or extinguishment of approximately $4.7 million for the nine months ended October 1, 2016 consisting of the proportionate write off of the related debt issuance costs and debt discount.

Income taxes

The income tax benefit for the nine months ended October 1, 2016 increased by approximately $46.8 million compared to the same period in 2015 primarily from the release of the valuation allowance of $50.1 million.  Our pre-tax income for the nine months ended October 1, 2016 was approximately $20.2 million including the $60.6 million tax receivable agreement liability adjustment compared to pre-tax income of $21.5 million including the $13.5 million tax receivable agreement liability adjustment for the nine months ended October 3, 2015.  For the nine months ended October 1, 2016, the income tax benefit increase resulted primarily from the release of the valuation allowance, partially offset by state income tax, remaining valuation allowances, and foreign income taxes.    

Liquidity and Capital Resources

During the nine months endedOctober 1, 2016, cash decreased by approximately $46.7 million compared to an increase of approximately $10.1 million during the nine months endedOctober 3, 2015.  The decrease in cash during the comparative nine month period was primarily driven by the $60.0 million in voluntary payments on the Term Loan Facility and a $20.0 million decrease in borrowings under the ABL Facility offset by the $46.2 million improvement in operating earnings period over period and the $21.0 million acquisition of Canyon Stone that occurred in 2015.

49

Two of the largest changes in operating cash flows during the nine months endedOctober 1, 2016 were the movement in accounts receivable and inventory. The approximate $88.5 million accounts receivable increase and $17.4 million inventory increase from December 31, 2015 to October 1, 2016 can be attributed to the seasonality of our business as we reach the peak building season in our second and third quarters. Net sales in the final two months of each respective quarter drove the receivables increase and the requirement for increased inventory as aging profiles were relatively consistent. Net sales for August and September 2016 were approximately $165.6 million and $208.4 million, respectively, versus approximately $136.2 million and $133.8 million for November and December 2015, respectively, an increase of $104.0 million. The improvement in August and September's net sales reflects the Company’s normal seasonal business as the weather in August and September is generally improved compared to November and December, which allows for further construction activity, increasing the Company’s sales with a corresponding increase in accounts receivable and inventory.

Our business is seasonal because inclement weather during the winter months typically reduces the level of building and remodeling activity in both the home repair and remodeling and new home construction sectors, especially in the Northeast and Midwest regions of the United States and Canada.  As a result, our liquidity typically increases during the second and third quarters as our ABL Facility borrowing base increases, reaching a peak early in the fourth quarter, and decreases late in the fourth quarter and throughout the first quarter.

Our primary cash needs are for working capital, capital expenditures, and debt service.  As of October 1, 2016, our annual cash interest charges for debt service for the year ending December 31, 2016, including the ABL Facility, is estimated to be approximately $59.0 million.  We do not have any scheduled debt maturities until 2020.  The specific debt instruments and their corresponding terms and due dates are described in the following sections.  Our capital expenditures have historically been approximately 1.5% to 2.0% of net sales on an annual basis.  Historically, we have been able to manage our capital expenditures based on market conditions for the new construction and repair and remodeling markets during any given fiscal year. As of October 1, 2016, we had no purchase commitments for inventory.  We finance these cash requirements, including payments under the Tax Receivable Agreement through internally generated cash flow and funds borrowed under the ABL Facility.

Our outstanding indebtedness will mature in 2020 (ABL Facility), 2021 (Term Loan Facility), and 2022 (6.50% Senior Notes).  Although we expect to refinance or pay off such indebtedness, we may not be successful in refinancing, extending the maturity or otherwise amending the terms of such indebtedness because of market conditions, disruptions in the debt markets, our financial performance or other reasons. Furthermore, the terms of any refinancing, extension or amendment may not be as favorable as the current terms of our indebtedness. If we are not successful in refinancing our indebtedness or extending its maturity, we and our subsidiaries could face substantial liquidity problems and may be forced to reduce or delay capital expenditures, sell assets, seek additional capital or restructure our indebtedness.

Our specific cash flow movement for the nine months endedOctober 1, 2016 and October 3, 2015 is summarized below:

Cash provided by operating activities

Net cash provided by operating activities for the nine months endedOctober 1, 2016 was $40.0 million as compared to approximately $35.8 million provided by operations for the nine months endedOctober 3, 2015. The net cash provided by operating activities was impacted by the operating earnings increase of $46.2 million which was driven by improved operating performance for our Windows and Doors segment of $23.7 million and $20.4 million operating earnings improvement in the Siding, Fencing and Stone segment based on improved U.S. housing market conditions for new construction and repair and remodeling. These improved housing conditions resulted in an unfavorable $36.8 million impact in our primary working capital for the nine months ended October 1, 2016 compared to the nine months ended October 3, 2015 as our net sales increased 2.9% which resulted in higher receivables and increased inventory requirements.

Cash used in investing activities

Net cash used in investing activities for the nine months endedOctober 1, 2016 and October 3, 2015 was approximately $26.3 million and $41.2 million, respectively, primarily used for capital expenditures on various ongoing capital projects. Capital expenditures for 2016 were higher than the 2015 comparable period at $26.4 million in 2016 versus $20.3 million, but were relatively consistent as a percentage of net sales at 1.8% for 2016 and 1.4% for 2015, which is comparable to our historical average of 1.5% to 2.0%. Additionally, the Company acquired Canyon Stone in May 2015 for $21.0 million.

Cash provided by (used in) financing activities

50

Net cash used in financing activities for the nine months endedOctober 1, 2016 was approximately $62.5 million, primarily from the two voluntary $30.0 million Term Loan Facility payments. Net cash provided by financing activities for the nine months endedOctober 3, 2015 was approximately $19.0 million, primarily from net revolver borrowings of $20.0 million. The decrease in borrowings under the revolver for 2016 related to improved operating performance during the nine months ended October 1, 2016 relative to the nine months ended October 3, 2015 as well as the $109.4 million cash balance carried forward from December 31, 2015.

Our specific debt instruments and terms are described below:

2015 Debt Transaction

On November 5, 2015, Ply Gem Industries entered into a second amended and restated ABL Facility. Among other things, the second amended and restated ABL Facility: (i) increased the overall facility to $350.0 million, (ii) provided an accordion feature of $50.0 million, and (iii) established the applicable margin for borrowings under the ABL Facility to a range of 1.25% to 2.00% for Eurodollar rate loans, depending on availability. All outstanding loans under the second amended and restated ABL Facility are due and payable in full on November 5, 2020.

6.50% Senior Notes due 2022

On January 30, 2014, Ply Gem Industries issued $500.0 million aggregate principal amount of 6.50% Senior Notes due 2022 (the "6.50% Senior Notes") at par. On September 19, 2014, Ply Gem Industries issued an additional $150.0 million aggregate principal amount of 6.50% Senior Notes at an issue price of 93.25%. Interest accrues at 6.50% per annum and is paid semi-annually on February 1 and August 1 of each year. All issued and outstanding 6.50% Senior Notes are registered under the Securities Act. The 6.50% Senior Notes will mature on February 1, 2022.

Prior to February 1, 2017, Ply Gem Industries may redeem up to 40% of aggregate principal amount of the 6.50% Senior Notes with the net cash proceeds from certain equity offerings at a redemption price equal to 106.50% of the aggregate principal amount of the 6.50% Senior Notes to be redeemed, plus accrued and unpaid interest, if any, provided that at least 50% of the aggregate principal amount of the 6.50% Senior Notes remains outstanding after the redemption. Prior to February 1, 2017, Ply Gem Industries may redeem the 6.50% Senior Notes, in whole or in part, at a redemption price equal to 100% of the principal amount plus a “make-whole” premium plus accrued and unpaid interest, if any. At any time on or after February 1, 2017, Ply Gem Industries may redeem the 6.50% Senior Notes, in whole or in part, at declining redemption prices set forth in the indenture governing the 6.50% Senior Notes plus, in each case, accrued and unpaid interest, if any, to the redemption date. The effective interest rate for the 6.50% Senior Notes is 8.39% after considering each of the different interest expense components of this instrument, including the coupon payment and the deferred debt issuance costs.

The 6.50% Senior Notes are fully and unconditionally and jointly and severally guaranteed on a senior unsecured basis by Ply Gem Holdings and all of the wholly-owned domestic subsidiaries of Ply Gem Industries (the “Guarantors”).  The indenture governing the 6.50% Senior Notes contains certain covenants that limit the ability of Ply Gem Industries and its restricted subsidiaries to incur additional indebtedness, pay dividends or make other distributions or repurchase or redeem their stock, make loans and investments, sell assets, incur certain liens, enter into agreements restricting their ability to pay dividends, enter into transactions with affiliates, and consolidate, merge or sell assets.  In particular, Ply Gem Industries and its restricted subsidiaries may not incur additional debt (other than permitted debt (as defined in the indenture) in limited circumstances) unless, after giving effect to such incurrence, the consolidated interest coverage ratio of Ply Gem Industries would be at least 2.00 to 1.00.  

In the absence of satisfying the consolidated interest coverage ratio test, Ply Gem Industries and its restricted subsidiaries may only incur additional debt under certain circumstances, including, but not limited to, debt under credit facilities (as defined in the indenture) (x) in an amount not to exceed the greater of (a) $350.0 million and (b) the borrowing base (as defined in the indenture) and (y) in an amount not to exceed the greater of (A) $575.0 million and (B) the aggregate amount of indebtedness (as defined in the indenture) that would cause the consolidated secured debt ratio (as defined in the indenture) to be equal to 4.00 to 1.00; purchase money indebtedness in an aggregate amount not to exceed the greater of (x) $35.0 million and (y) 10% of consolidated net tangible assets (as defined in the indenture) at any one time outstanding; debt of foreign subsidiaries in an aggregate amount not to exceed the greater of (x) $60.0 million and (y) 15% of consolidated net tangible assets (as defined in the indenture) at any one time outstanding; debt pursuant to a general basket in an aggregate amount at any one time outstanding not to exceed the greater of (x) $75.0 million and (y) 20% of consolidated net tangible assets; and the refinancing of debt under certain circumstances.

51

Term Loan Facility due 2021

On January 30, 2014, Ply Gem Industries entered into a credit agreement governing the terms of its $430.0 million Term Loan Facility. Ply Gem Industries originally borrowed $430.0 million under the Term Loan Facility on January 30, 2014, with an original discount of approximately $2.2 million, yielding proceeds of approximately $427.9 million. The Term Loan Facility will mature on January 30, 2021. The Term Loan Facility requires scheduled quarterly payments in an aggregate annual amount equal to 1.00% of the original aggregate principal amount of the Term Loan Facility with the balance due at maturity. Interest on outstanding borrowings under the Term Loan Facility is paid quarterly.

Borrowings under the Term Loan Facility bear interest at a rate equal to, at Ply Gem Industries’ option, either (a) a base rate determined by reference to the highest of (i) the prime rate of the administrative agent under the credit agreement, (ii) the federal funds rate plus 0.50% and (iii) the adjusted LIBO rate for a one-month interest period plus 1.00% or (b) a LIBO rate determined by reference to the cost of funds for eurocurrency deposits in dollars for the interest period relevant to such borrowing, adjusted for certain additional costs, subject to a 1.00% floor, plus, in each case, an applicable margin of 3.00% for any eurocurrency loan and 2.00% for any alternate base rate loan. As of October 1, 2016, the Company's interest rate on the Term Loan Facility was 4.00%. The effective interest rate for the Term Loan is 7.38% after considering each of the different interest expense components of this instrument, including the coupon payment, the deferred debt issuance costs and the original issue discount.

The Term Loan Facility allows Ply Gem Industries to request one or more incremental term loan facilities in an aggregate amount not to exceed the greater of (x) $140.0 million and (y) an amount such that Ply Gem Industries’ consolidated senior secured debt ratio (as defined in the credit agreement), on a pro forma basis, does not exceed 3.75 to 1.00, in each case, subject to certain conditions and receipt of commitments by existing or additional financial institutions or institutional lenders.

The Term Loan Facility requires Ply Gem Industries to prepay outstanding term loans, subject to certain exceptions, with: (i) 50% (which percentage will be reduced to 25% if our consolidated senior secured debt ratio is equal or less than 2.50 to 1.00 but greater than 2.00 to 1.00 and to 0% if our consolidated senior secured debt ratio is equal to or less than 2.00 to 1.00) of our annual excess cash flow (as defined in the credit agreement), to the extent such excess cash flow exceeds $15.0 million; (ii) 100% of the net cash proceeds of certain non-ordinary course asset sales or certain insurance and condemnation proceeds, in each case subject to certain exceptions and reinvestment rights; and (iii) 100% of the net cash proceeds of certain issuances of debt, other than proceeds from debt permitted under the Term Loan Facility. Ply Gem Industries may voluntarily repay outstanding loans under the Term Loan Facility at any time without premium or penalty, other than customary “breakage” costs with respect to LIBOR loans. As of and for the year ended December 31, 2015, the Company's consolidated senior secured debt ratio was 1.97 and as a result no excess cash flow payment under the Term Loan Facility was required. However, the Company elected on March 10, 2016 and August 4, 2016 to voluntarily prepay $30.0 million on each date on the Term Loan Facility to reduce its outstanding indebtedness. The Company further elected on November 4, 2016 to voluntarily pay an additional $100.0 million on the Term Loan Facility to further reduce its outstanding indebtedness bringing our cumulative voluntary 2016 Term Loan Facility payments to $160.0 million.

The Term Loan Facility is secured on a first-priority lien basis by the stock of Ply Gem Industries and by substantially all of the assets (other than the assets securing the obligations under the ABL Facility, which primarily consist of accounts receivable, inventory, cash, deposit accounts, securities accounts, chattel paper, contract rights, instruments, documents related thereto and proceeds of the foregoing) of Ply Gem Industries and the Guarantors that are subsidiaries of Ply Gem Industries and on a second-priority lien basis by the assets that secure the ABL Facility.

The Term Loan Facility includes negative covenants, subject to certain exceptions, that are substantially the same as the negative covenants in the 6.50% Senior Notes but does not contain any restrictive financial covenants. The Term Loan Facility also restricts the ability of Ply Gem Industries’ subsidiaries to enter into agreements restricting their ability to grant liens to secure the Term Loan Facility and contains a restriction on changes in fiscal year.

Senior Secured Asset Based Revolving Credit Facility due 2020

52

On November 5, 2015, Ply Gem Holdings, Inc., Ply Gem Industries, Inc., Gienow Canada Inc., and Mitten Inc. (together with Gienow, the “Canadian Borrowers”) entered into a second amended and restated credit agreement governing the ABL Facility. Among other things, the second amendment and restatement of the credit agreement governing the ABL Facility: (i) increased the overall facility to $350.0 million from $300.0 million, (ii) established an accordion feature of $50.0 million, (iii) reduced the applicable margin for borrowings under the ABL Facility to a range from 1.25% to 2.00% for Eurodollar rate loans, depending on availability, and (iv) extended the maturity until November 5, 2020. Under the ABL Facility, $300.0 million is available to Ply Gem Industries and $50.0 million is available to the Canadian Borrowers. The following summary describes the ABL Facility after giving effect to the second amendment and restatement. As a result of the November 2015 ABL Facility amendment in which the loan syndication consisted of previous members who either maintained or increased their position as well as new syndication members, the Company capitalized new debt issuance costs of $1.5 million and will amortize these costs through 2020.

Borrowings under the ABL Facility bear interest at a rate per annum equal to, at Ply Gem Industries’ option, either (a) a base rate determined by reference to the higher of (1) the corporate base rate of the administrative agent under the ABL Facility and (2) the federal funds rate plus 0.5% or (b) a Eurodollar rate determined by reference to the costs of funds for U.S. dollar deposits for the interest period relevant to such borrowing adjusted for certain additional costs, in each case plus an applicable margin.  The initial applicable margin for borrowings under the ABL Facility was 0.50% for base rate loans and 1.50% for Eurodollar rate loans.  The applicable margin for borrowings under the ABL Facility is subject to step ups and step downs based on average excess availability under the ABL Facility.  Swingline loans bear interest at a rate per annum equal to the base rate plus the applicable margin.

In addition to paying interest on outstanding principal under the ABL Facility, Ply Gem Industries is required to pay a commitment fee in respect of the unutilized commitments thereunder, which fee will be determined based on utilization of the ABL Facility (increasing when utilization is low and decreasing when utilization is high) multiplied by a commitment fee rate determined by reference to average excess availability under the ABL Facility. The commitment fee rate during any fiscal quarter is 0.375% when average excess availability is greater than $100.0 million for the preceding fiscal quarter and 0.25% when average availability is less than or equal to $100.0 million for the preceding fiscal quarter.  Ply Gem Industries must also pay customary letter of credit fees equal to the applicable margin on Eurodollar loans and agency fees.   As of October 1, 2016, the Company’s interest rate on the ABL Facility was approximately 1.88%.  The ABL Facility requires that if (a) excess availability is less than the greater of (x) 10.0% of the lower of the borrowing base and the aggregate commitments and (y) $25.0 million or (b) any event of default has occurred and is continuing, Ply Gem Industries must comply with a minimum fixed charge coverage ratio test of 1.0 to 1.0.  If the excess availability under the ABL Facility is less than the greater of (a) 12.5% of the lesser of the borrowing base and the aggregate commitments and (b) $30.0 million ($27.5 million for the months of January, February, March and April) for a period of 5 consecutive days or an event of default has occurred and is continuing, all cash from Ply Gem Industries material deposit accounts (including all concentration accounts) will be swept daily into a collection account controlled by the administrative agent under the ABL Facility and used to repay outstanding loans and cash collateralize letters of credit.

All obligations under the ABL Facility are unconditionally guaranteed by Ply Gem Holdings and substantially all of Ply Gem Industries’ existing and future, direct and indirect, wholly owned domestic subsidiaries.  All obligations under the ABL Facility, and the guarantees of those obligations, are secured, subject to certain exceptions, by substantially all of the assets of Ply Gem Industries and the guarantors, including a first-priority security interest in personal property consisting of accounts receivable, inventory, cash, deposit accounts, and certain related assets and proceeds of the foregoing and a second-priority security interest in, and mortgages on, substantially all of Ply Gem Industries’ and the Guarantors’ material owned real property and equipment and all assets that secure the Term Loan Facility on a first-priority basis.  In addition to being secured by the collateral securing the obligations of Ply Gem Industries under the domestic collateral package, the obligations of the Canadian Borrowers, which are borrowers under the Canadian sub-facility under the ABL Facility, are also secured by a first-priority security interest in substantially all of the assets of such Canadian subsidiaries, plus additional mortgages in Canada, and a pledge by Ply Gem Industries of the remaining 35% of the equity interests of the Canadian Borrowers pledged only to secure the Canadian sub-facility.

The ABL Facility contains certain covenants that limit Ply Gem Industries’ ability and the ability of Ply Gem Industries’ subsidiaries to incur additional indebtedness, pay dividends or make other distributions or repurchase or redeem their stock, make loans and investments, sell assets, incur certain liens, enter into transactions with affiliates, and consolidate, merge or sell assets.  

As of October 1, 2016, Ply Gem Industries had approximately $339.4 million of contractual availability and approximately $274.0 million of borrowing base availability under the ABL Facility, reflecting $0.0 million of borrowings outstanding and approximately $10.6 million of letters of credit and priority payables reserves.

Loss on debt modification or extinguishment

During both March and August 2016, the Company made voluntarily payments of $30.0 million on the Term Loan Facility to reduce its outstanding indebtedness as allowable under the terms of the Term Loan Facility totaling $60.0 million during 2016. The Company performed an analysis to determine the proper accounting treatment for each of these voluntary payments by evaluating the change in cash flows and determined that there were no changes in creditors as a result of the payments. Consequently, the Company recognized a loss on debt modification or extinguishment of approximately $2.3 million and $4.7 million for the three and nine months endedOctober 1, 2016, respectively, reflecting the proportionate write-off of the related debt discount and debt issuance costs associated with each $30.0 million payment, as summarized in the table below.

(Amounts in thousands)	For the three months ended				For the nine months ended
	October 1, 2016		October 3, 2015		October 1, 2016		October 3, 2015

Total loss on modification or extinguishment of debt	$	2,251	$	—	$	4,650	$	—

Liquidity requirements

We intend to fund our ongoing capital and working capital requirements, including our internal growth, through a combination of cash flows from operations and, if necessary, from borrowings under our ABL Facility.  We believe that we will continue to meet our liquidity requirements over the next 12 months.  We believe that our operating units are positive cash flow generating units and will continue to sustain their operations without any significant liquidity concerns.  The performance of these operating units is significantly impacted by the performance of the housing industry, specifically single family housing starts and the repair and remodeling activity.  Any unforeseen or unanticipated downturn in the housing industry could have a negative impact on our liquidity position.

Management anticipates that our current liquidity position, as well as expected cash flows from our operations, should be sufficient to meet ongoing operational cash flow needs, capital expenditures, debt service obligations, and other fees payable under other contractual obligations for the foreseeable future.  As of October 1, 2016, we had cash and cash equivalents of approximately $62.7 million, approximately $339.4 million of contractual availability under the ABL Facility and approximately $274.0 million of borrowing base availability.  

In order to further supplement our operating cash flow, we have from time to time opportunistically accessed capital markets based on prevailing economic and financial conditions.  Based on market conditions, we may elect to pursue additional financing alternatives in the future. 

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements.

Contractual Obligations

In addition to the items listed in the Contractual Obligations table presented in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015, we have a potential obligation related to certain tax matters of approximately $3.1 million, including interest and penalties of approximately $1.3 million.  The timing of the potential tax payments is unknown.

As of October 1, 2016, the Company had no inventory purchase commitments.

54

Inflation; Seasonality

Our performance is dependent to a significant extent upon the levels of home repair and remodeling and new home construction spending, all of which are affected by such factors as interest rates, inflation, consumer confidence and unemployment.  We do not believe that inflation has had a material impact on our business, financial condition or results of operations during the past three fiscal years.

The demand for our products is seasonal, particularly in the Northeast and Midwest regions of the United States and Canada where inclement weather conditions during the winter months usually reduces the level of building and remodeling activity in both the home repair and remodeling and the new home construction sectors.  Our sales in both segments are usually lower during the first and fourth quarters.  Since a portion of our manufacturing overhead and operating expenses are relatively fixed throughout the year, operating income and net earnings tend to be lower in quarters with lower sales levels.  In addition, the demand for cash to fund our working capital is greater from late in the fourth quarter through the first quarter.

Recent Accounting Pronouncements

See Note 1 – Summary of Significant Accounting Policies to the condensed consolidated financial statements, regarding the impact of certain recent accounting pronouncements on our condensed consolidated financial statements.

Special Note Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995.  These statements relate to future events or our future financial performance.  In some cases, you can identify forward-looking statements by terminology such as "may", "will", "should", "expect", "plan", "anticipate", "believe", "estimate", "predict", "potential" or "continue", the negative of such terms or other comparable terminology.  These statements are only predictions.  Actual events or results may differ materially.

Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance or achievements. Moreover, neither we nor any other person assumes responsibility for the accuracy and completeness of the forward-looking statements.  All written and oral forward-looking statements made in connection with this Quarterly Report on Form 10-Q that are attributable to us or persons acting on our behalf are expressly qualified in their entirety by the Risk Factors set forth in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015 and other cautionary statements included therein and herein.

There can be no assurance that other factors will not affect the accuracy of these forward-looking statements or that our actual results will not differ materially from the results anticipated in such forward-looking statements. While it is impossible to identify all such factors, factors which could cause actual results to differ materially from those estimated by us include, but are not limited to, those factors or conditions described under Risk Factors in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015, and the following:

• our high degree of leverage and significant debt service obligations;

• restrictions under the indenture governing the 6.50% Senior Notes and the restrictions under our Term Loan Facility and ABL Facility;

• the competitive nature of our industry;

• changes in interest rates, and general economic, home repair and remodeling and new home construction market conditions;

• changes in the price and availability of raw materials; and

• changes in our relationships with our significant customers.

Other factors that could cause actual results to differ from those implied by the forward-looking statements contained in this Quarterly Report on Form 10-Q include those set forth in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015.  We undertake no obligation to update the forward-looking statements in this report.

55

Item 3.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

Our principal interest rate exposure relates to the loans outstanding under our Term Loan Facility and our ABL Facility, which provides for borrowings of $430.0 million on the Term Loan and up to $350.0 million on the ABL, bearing interest at a variable rate, based on an adjusted LIBOR rate plus an applicable interest margin or the base rate plus an applicable interest margin.  Each quarter point increase or decrease in the interest rate would change our interest expense by approximately $1.1 million per year for the Term Loan Facility.  Assuming the ABL Facility is fully drawn, each quarter point increase or decrease in the interest rate would change our interest expense by approximately $0.9 million per year. At October 1, 2016, we were not party to any interest rate swaps or caps to manage our interest rate risk. In the future, we may enter into interest rate swaps or interest rate caps, involving exchange of floating for fixed rate interest payments, to reduce our exposure to interest rate volatility.

Foreign Currency Risk

Our results of operations are affected by fluctuations in the value of the U.S. dollar as compared to the value of the Canadian dollar.  For the three and nine months ended October 1, 2016, the net impact of foreign currency changes to our results of operations was a loss of $0.1 million and a gain of approximately $0.7 million, respectively. The impact of foreign currency changes related to translation resulted in an decrease in stockholders' deficit of approximately $4.1 million for the nine months endedOctober 1, 2016. The revenue or expense reported by us as a result of currency fluctuations will be greater in times of U.S. dollar devaluation and less in times of U.S. dollar appreciation. During 2015 and 2016, we entered into forward contracts to mitigate the exposure risk of currency fluctuation against the Canadian dollar.  At October 1, 2016, our foreign currency hedging contract had a fair value of $0.3 million and is recorded as an asset as of October 1, 2016.

Commodity pricing risk

We are subject to significant market risk with respect to the pricing of our principal raw materials, which include PVC resin, aluminum, and wood.  If prices of these raw materials were to increase dramatically, we may not be able to pass such increases on to our customers and, as a result, gross margins could decline significantly.  We manage the exposure to commodity pricing risk by increasing our selling prices for corresponding material cost increases, continuing to diversify our product mix, strategic buying programs and vendor partnering. The Midwest Ingot price of aluminum decreased approximately 14.5% for the nine months ended October 1, 2016 compared to the nine months ended October 3, 2015. The average market price for PVC resin was estimated to have increased approximately 3.2% for the nine months ended October 1, 2016 compared to the nine months ended October 3, 2015.

Inflation

We do not believe that inflation, net of our corresponding price increases for material cost, has had a material effect on our business, financial condition or results of operations.  Our lease payments related to our sale/leaseback agreement include an annual increase based on the Consumer Price Index, which could expose us to potential higher costs in years with high inflation. The CPI increase for the twelve months ended September 2016 was approximately 1.5%.

Labor force risk

Our manufacturing process is highly engineered but involves manual assembly, fabrication, and manufacturing processes. We believe that our success depends upon our ability to employ, train, and retain qualified personnel with the ability to design, utilize and enhance these services and products. In addition, our ability to expand our operations depends in part on our ability to increase our labor force as the U.S. housing market recovers and minimize labor inefficiencies. A significant increase in the wages paid by competing employers could result in a reduction of our labor force, increases in the wage rates that we must pay, or both. If either of these events were to occur, our cost structure could increase, our margins could decrease and any growth potential could be impaired. Historically, the Company has believed that the lag period between breaking ground on a new housing start and the utilization of our products on the exterior of a home is between 90 to 120 days.

56

Item 4.     CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management maintains disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding the required disclosure.

Our management is responsible for establishing and maintaining our disclosure controls and procedures. Our Chief Executive Officer and Chief Financial Officer participated with our management in evaluating the effectiveness of our disclosure controls and procedures as of October 1, 2016.  Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures as of October 1, 2016 were effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and (ii) accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding the required disclosure.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting during the three months ended October 1, 2016 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Our Chief Executive Officer and Chief Financial Officer have each concluded that the consolidated financial statements included in this Quarterly Report on Form 10-Q present fairly, in all material respects, the financial position, results of operations and cash flows of the Company and its subsidiaries in conformity with GAAP.

Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of Ply Gem Holdings, Inc. and its subsidiaries (referred to herein as “Ply Gem Holdings”, “Ply Gem”, the “Company”, “we”, “us”, or “our”) have been prepared in accordance with U.S. generally accepted accounting principles as described in the consolidated financial statements and related notes included in our 2015 Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 14, 2016.  These statements do not include all of the information and footnotes required by U.S. generally accepted accounting principles and should be read in conjunction with our 2015 Annual Report on Form 10-K.  In management’s opinion, all normal and recurring adjustments considered necessary for a fair presentation have been included.  Operating results for the period from January 1, 2016 through October 1, 2016 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016.

The condensed consolidated balance sheet at December 31, 2015 has been derived from the audited consolidated financial statements of Ply Gem Holdings at that date, but does not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements.

The Company’s fiscal quarters are based on periods ending on the Saturday of the last week in the quarter.  Therefore, the financial results of certain fiscal quarters will not be comparable to the prior and subsequent fiscal quarters.  The accompanying financial statements include the Company’s condensed consolidated statements of operations and comprehensive income (loss) for the three and nine months ended October 1, 2016 and October 3, 2015, the condensed consolidated statements of cash flows for the nine months endedOctober 1, 2016 and October 3, 2015, and the condensed consolidated balance sheets as of October 1, 2016 and December 31, 2015.

Ply Gem is a diversified manufacturer of residential and commercial building products, which are sold primarily in the United States and Canada, and include a wide variety of products for the residential and commercial construction, the do-it-yourself and the professional remodeling and renovation markets.  The demand for the Company’s products is seasonal, particularly in the Northeast and Midwest regions of the United States and Canada where inclement weather during the winter months usually reduces the level of building and remodeling activity in both the home repair and remodeling and new home construction sectors.  The Company’s sales are usually lower during the first and fourth quarters.

To a significant extent our performance is dependent upon the levels of home repair and remodeling and new home construction spending, all of which are affected by such factors as interest rates, inflation, consumer confidence, unemployment, and availability of consumer credit.

Principles of Consolidation

The condensed consolidated financial statements include the accounts of Ply Gem Holdings and its subsidiaries, all of which are wholly owned.  All intercompany accounts and transactions have been eliminated.

Reclassifications

Due to the adoption of ASU No. 2015-03, Interest-Imputation of Interest, certain balance sheet amounts in the prior fiscal year have been reclassified to conform to the presentation adopted in the current fiscal year, with no effect on net income, accumulated deficit, or net cash provided by (used in) operating, investing, and financing activities. Refer to Note 5, Long-Term Debt, for the presentation impact on net debt.

Accounting Policies and Use of Estimates

The preparation of these condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles involves estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of income and expense during the reporting periods.  Certain of the Company’s accounting policies require the application of judgment in selecting the appropriate assumptions for calculating financial estimates.  By their nature, these judgments are subject to an inherent degree of uncertainty.  The Company periodically evaluates the judgments and estimates used in their critical accounting policies to ensure that such judgments and estimates are reasonable.  Such estimates include the allowance for doubtful accounts receivable, rebates, pensions, valuation of inventories, warranty reserves, insurance reserves, legal contingencies, assumptions used in the calculation of income taxes and the tax receivable agreement liability, projected cash flows used in the goodwill and intangible asset impairment tests, and environmental accruals and other contingencies.  These judgments are based on the Company’s historical experience, current trends and information available from other sources, and are based on management’s best estimates and judgments.  The Company adjusts such estimates and assumptions when facts and circumstances dictate.  Volatile equity markets, foreign currency, and litigation risk have combined to increase the uncertainty inherent in such estimates and assumptions.  If different conditions result from those assumptions used in the Company’s judgments, actual results could be materially different from the Company’s estimates.

Cash and Cash Equivalents

Cash equivalents consist of short-term highly liquid investments with original maturities of three months or less and which are readily convertible into cash.

Accounts Receivable

Accounts receivable-trade are recorded at their net realizable value.  The allowance for doubtful accounts was $3.0 million at October 1, 2016 and $3.6 million at December 31, 2015.  The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The Company estimates the allowance for doubtful accounts based on a variety of factors including the length of time receivables are past due, the financial health of its customers, unusual macroeconomic conditions and historical experience. If the financial condition of its customers deteriorates or other circumstances occur that result in an impairment of customers’ ability to make payments, the Company records additional allowances as needed. The Company writes off uncollectible trade accounts receivable against the allowance for doubtful accounts when collection efforts have been exhausted and/or any legal action taken by the Company has concluded.

Inventories

Inventories in the accompanying condensed consolidated balance sheets are valued at the lower of cost or net realizable value and are determined primarily by the first-in, first-out (FIFO) method.  The Company records provisions, as appropriate, to write-down obsolete and excess inventory to estimated net realizable value.  The process for evaluating obsolete and excess inventory often requires the Company to make subjective judgments and estimates concerning future sales levels, quantities and prices at which such inventory will be able to be sold in the normal course of business.  Accelerating the disposal process or incorrect estimates of future sales potential may cause actual results to differ from the estimates at the time such inventory is disposed or sold. As of October 1, 2016, the Company has no inventory purchase commitments.

Inventory provisions were approximately $9.6 million at October 1, 2016, increasing during the nine months endedOctober 1, 2016 by $1.3 million compared to the December 31, 2015 provision balance of approximately $8.3 million.

Property and Equipment

Property and equipment are presented at cost.  Depreciation of property and equipment are provided on a straight-line basis over estimated useful lives, which are generally as follows: 

Buildings and improvements	10-37 years
Machinery and equipment, including leases	3-15 years
Leasehold improvements	Term of lease or useful life, whichever is shorter

Expenditures for maintenance and repairs are expensed when incurred. Expenditures for renewals and betterments are capitalized.  When assets are sold, or otherwise disposed, the cost and related accumulated depreciation are eliminated and the resulting gain or loss is recognized in operations.  

Intangible Assets, Goodwill and Other Long-lived Assets

Acquisitions

On May 29, 2015, Ply Gem completed an acquisition for cash consideration of approximately $21.0 million to acquire substantially all of the assets of Canyon Stone Inc. ("Canyon Stone"), a manufacturer and distributor of stone veneer and accessories in the United States. Canyon Stone has manufacturing facilities in Olathe, Kansas and Youngsville, North Carolina. The purchase agreement also includes contingent consideration in the form of potential earn-out payments of up to $1.0 million based on Canyon Stone's earnings for fiscal years 2015 through 2017. This acquisition expanded the Company's stone veneer manufacturing footprint across the United States as it complements the existing Ply Gem Stone manufacturing facility. The Company accounted for the transaction as an acquisition in accordance with the provisions of Accounting Standards Codification 805, Business Combinations, which results in a new valuation for the assets and liabilities of Canyon Stone based upon fair values as of the acquisition date.

The Company determined the fair value of the tangible and intangible assets and the liabilities acquired, and recorded goodwill based on the excess of fair value of the acquisition consideration over such fair values, as follows:

(Amounts in thousands)
Accounts receivable	$	3,559
Inventories	712
Prepaid expenses and other current assets	41
Property and equipment	2,019
Intangible assets	9,300
Goodwill	7,642
Accounts payable, accrued expenses and other long-term liabilities	(2,273		)
	$	21,000

The $7.6 million of goodwill was allocated to the Siding, Fencing and Stone segment and the goodwill is expected to be deductible for tax purposes. The Company has recognized a liability of approximately $0.8 million as the estimated acquisition date fair value of the earn-out as of October 1, 2016 and December 31, 2015. This amount is included within other long-term liabilities in the condensed consolidated balance sheets. Any change in the fair value of the contingent consideration subsequent to the acquisition date will be recognized in earnings in the period of change.

Long-lived assets

The Company reviews long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable.  The Company performs an undiscounted operating cash flow analysis to determine if impairment exists.  If an impairment is determined to exist, any related impairment loss is calculated based on the asset’s fair value and the discounted cash flows.

The Company tests for long-lived asset impairment at the following asset group levels: (i) the combined U.S. Siding, Fencing and Stone companies in the Siding, Fencing and Stone segment (“Siding”), (ii) the combined U.S. Windows companies in the Windows and Doors segment (“U.S. Windows”), (iii) the combined Simonton windows companies in the Windows and Doors segment, (iv) Gienow Canada Inc. ("Gienow Canada") (a combined Western Canadian company created by the January 2014 amalgamation of the Company's legacy Western Canadian business and the Gienow entity acquired in April 2013) in the Windows and Doors segment, and (v) Mitten in the Siding, Fencing and Stone segment. For purposes of recognition and measurement of an impairment loss, a long-lived asset or asset group should represent the lowest level for which an entity can separately identify cash flows that are largely independent of the cash flows of other assets and liabilities.  There were no indicators of impairment during the three and nine months ended October 1, 2016.

Goodwill and other intangible assets

The Company evaluates goodwill for impairment on an annual basis and whenever events or business conditions warrant.  All other intangible assets are amortized over their estimated useful lives and are assessed for impairment as necessary.  The Company assesses goodwill for impairment at the November month end each year and also at any other date when events or changes in circumstances indicate that the carrying value of these assets may exceed their fair value.  To evaluate goodwill for impairment, the Company estimates the fair value of reporting units considering such factors as discounted cash flows and valuation multiples for comparable publicly traded companies.  A significant reduction in projected sales and earnings, which would lead to a reduction in future cash flows, could indicate potential impairment.  There were no indicators of impairment during the three and nine months ended October 1, 2016 that would trigger an interim impairment test.  The Company will continue to evaluate goodwill during future periods and future declines in the residential housing and repair and remodeling markets could result in goodwill impairments.

Debt Issuance Costs

Debt issuance costs, composed of facility, agency, and certain legal fees associated with issuing new debt financing, are amortized over the contractual term of the related agreement using the effective interest method.  Net debt issuance costs totaled approximately $18.8 million and $22.2 million as of October 1, 2016 and December 31, 2015, respectively, and have been recorded within long-term debt ($16.4 million at October 1, 2016 and $19.3 million at December 31, 2015) and other non-current assets ($2.5 million at October 1, 2016 and $2.9 million at December 31, 2015) in the accompanying condensed consolidated balance sheets. The debt issuance costs included in other long term assets relate to the Senior Secured Asset Based Revolving Credit Facility due 2020 ("ABL Facility"). Amortization of debt issuance costs for the three months ended October 1, 2016 and October 3, 2015 was approximately $0.8 million and $0.8 million, respectively. Amortization of debt issuance costs for the nine months endedOctober 1, 2016 and October 3, 2015 was approximately $2.5 million and $2.3 million, respectively. Amortization of debt issuance costs is recorded in interest expense in the accompanying condensed consolidated statements of operations and comprehensive income.

Income Taxes

The Company utilizes the asset and liability method of accounting for income taxes which requires that deferred tax assets and liabilities be recorded to reflect the future tax consequences of temporary differences between the book and tax basis of various assets and liabilities.  Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.  The effect of changes in tax rates on deferred tax assets and liabilities is recognized as income or expense in the period in which the rate change occurs.  A valuation allowance is established to offset any deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

Estimates are required with respect to, among other things, the appropriate state income tax rates used in the various states that the Company and its subsidiaries are required to file, the potential utilization of operating and capital loss carry-forwards for both federal and state income tax purposes and valuation allowances required, if any, for deferred tax assets that may not be realized in the future.  The Company establishes reserves when, despite our belief that our tax return positions are fully supportable, certain positions could be challenged, and the positions may not be fully sustained.  The Company, along with its U.S. subsidiaries, file a consolidated federal income tax return, separate state income tax returns, combined state returns, and unitary state returns. Gienow Canada and Mitten both file separate Canadian federal income tax returns and separate provincial returns.

Tax receivable agreement ("TRA") liability

The TRA liability generally provides for the payment by the Company to the Tax Receivable Entity of 85% of the amount of cash savings, if any, in the U.S. federal, state and local income tax that the Company actually realizes in periods ending after the Company's initial public offering as a result of (i) net operating loss carryovers ("NOLs") from periods ending before January 1, 2013, (ii) deductible expenses attributable to the initial public offering and (iii) deductions related to imputed interest. Since the inception of the TRA liability with the Company’s 2013 initial public offering, the Company has been in a full valuation allowance for federal purposes and had partial valuation allowances on certain state and Canadian jurisdictions. As a result of the Company’s tax valuation allowance position for federal and state purposes, the Company calculated the TRA liability considering (i) current year taxable income only (due to the uncertainty of future taxable income associated with the Company’s cumulative loss position) and (ii) future income due to the expected reversals of deferred tax liabilities. During the three and nine months ended October 1, 2016, the Company released its valuation allowance on its federal deferred tax assets and certain state deferred tax assets for approximately $50.1 million due to positive factors outweighing negative evidence thereby allowing the Company to achieve the “more likely than not” realization threshold. This release thereby eliminated any uncertainty as to future taxable income. Consequently, for purposes of calculating the TRA liability, the Company during the three months ended October 1, 2016 utilized future forecasts of taxable income beyond the 2016 tax year to determine the TRA liability. The Company’s future taxable income estimate was used to determine the cumulative NOLs that are expected to be utilized and the TRA liability was accordingly adjusted using the 85% TRA rate as the Company retains the benefit of 15% of the tax savings.

Environmental

The Company accrues for losses associated with environmental remediation obligations when such losses are probable and reasonably estimable. Environmental remediation obligation accruals are adjusted as further information develops or circumstances change.  Costs of future expenditures for environmental remediation obligations are not discounted to their present value.  Recoveries of environmental remediation costs from other parties are recorded as assets when their receipt is deemed probable.

Commitments and Contingencies

The Company accrues for all direct costs associated with the estimated resolution of contingencies at the earliest date at which it is deemed probable that a liability has been incurred and the amount of such liability can be reasonably estimated.  Costs accrued have been estimated based upon an analysis of potential results, assuming a combination of litigation and settlement strategies and outcomes. Insurance recoveries are recorded as assets when their receipt is deemed probable.

Foreign Currency

Gienow Canada and Mitten, the Company’s Canadian subsidiaries, utilize the Canadian dollar as their functional currency.  For reporting purposes, the Company translates the assets and liabilities of its foreign entities at the exchange rates in effect at period-end.  Net sales and expenses are translated using average exchange rates in effect during the period.  Gains and losses from foreign currency translation are credited or charged to accumulated other comprehensive income or loss in the accompanying condensed consolidated balance sheets.

The Company recorded a loss from foreign currency transactions of approximately $0.1 million and $1.1 million for the three months ended October 1, 2016 and October 3, 2015, respectively. The Company recorded a gain from foreign currency transactions of approximately $0.7 million for the nine months ended October 1, 2016 and a loss of approximately $2.1 million for the nine months ended October 3, 2015. During the nine months ended October 1, 2016, accumulated other comprehensive income (loss) included a currency translation gain of approximately $4.1 million and a loss of approximately $11.3 million for the nine months ended October 3, 2015.

Derivative Financial Instruments

As of October 1, 2016, the Company had entered into foreign currency forward contract agreements to hedge approximately $78.1 million of its 2016 and 2017 non-functional currency inventory purchases to protect the Company from variability in cash flows attributable to changes in the U.S. dollar relative to the Canadian dollar.

The Company has designated these forward contracts as cash flow hedges. As a cash flow hedge, unrealized gains are recognized as assets while unrealized losses are recognized as liabilities. These forward contract agreements are highly correlated to the changes in foreign currency rates to which the Company is exposed. Unrealized gains and losses on these agreements are designated as effective or ineffective. The effective portion of such gains or losses is recorded as a component of accumulated other comprehensive income or loss, while the ineffective portion of such gains or losses is recorded as a component of cost of goods sold. Future realized gains and losses in connection with each inventory purchase will be reclassified from accumulated other comprehensive income or loss to cost of goods sold.

The changes in fair values of derivatives that have been designated and qualify as cash flow hedges are recorded in accumulated other comprehensive income or loss and are reclassified into cost of goods sold in the same period the hedged item affects earnings. Due to the high degree of effectiveness between the hedging instruments and the underlying exposures being hedged, fluctuations in the value of the derivative instrument are generally offset by changes in the fair value or cash flows of the underlying exposures being hedged. The changes in the fair value of derivatives that do not qualify as effective are immediately recognized in earnings.

The gains and losses on derivative contracts that are reclassified from accumulated other comprehensive income or loss to current period earnings are included in the line item in which the hedged item is recorded in the same period the forecasted transaction affects earnings. As of October 1, 2016, approximately $0.3 million of the deferred net asset on derivative instruments included in accumulated other comprehensive loss is expected to be reclassified to cost of goods sold during the next twelve months. This expectation is based on the expected timing of the occurrence of the hedged forecasted transactions. During the three and nine months ended October 1, 2016, the Company recognized $0.2 million and $0.5 million, respectively, within earnings as an increase to cost of goods sold in the condensed consolidated statement of operations and comprehensive income. During the three and nine months ended October 3, 2015, the Company recognized $1.8 million and $3.9 million, respectively, within earnings as a reduction of cost of goods sold in the condensed consolidated statement of operations and comprehensive income.

The fair value of the foreign currency forward contract agreements are estimated using industry standard valuation models using market-based observable inputs, including spot rates, forward points, interest rates and volatility inputs (Level 2). A summary of the recorded asset and liability included in the accompanying condensed consolidated balance sheets is as follows:

(Amounts in thousands)	October 1, 2016		December 31, 2015
Foreign currency hedge included in other current assets	$	335	$	829

Fair Value Measurement

The accounting standard for fair value discusses valuation techniques, such as the market approach (comparable market prices), the income approach (present value of future income or cash flows), and the cost approach (cost to replace the service capacity of an asset or replacement cost). The standard utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels:

• Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities.

• Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.

• Level 3: Inputs that reflect the reporting entity’s own assumptions.

The hierarchy requires the use of observable market data, when available, and to minimize the use of unobservable inputs when determining fair value.  The fair value of the long-term debt instruments was determined by utilizing available market information.  The carrying value of the Company’s other assets and liabilities approximates their fair value. The Company’s population of recurring financial assets and liabilities subject to fair value measurements and the necessary disclosures are as follows:

Earnings (Loss) Per Common Share

Basic earnings (loss) per share ("EPS") is computed based upon weighted-average shares outstanding during the period. Dilutive earnings per share is computed consistently with the basic computation while giving effect to all dilutive potential common shares and common share equivalents that were outstanding during the period. Ply Gem Holdings uses the treasury stock method to reflect the potential dilutive effect of unvested stock awards and unexercised options.

The computation of the dilutive effect of other potential common shares included options and unvested restricted stock representing approximately 0.2 million and 0.1 million shares of common stock for the three and nine months endedOctober 1, 2016, respectively. The computation of the dilutive effect of other potential common shares included options and unvested restricted stock representing approximately 0.1 million and 0.1 million shares of common stock for the three and nine months ended October 3, 2015, respectively.

New Accounting Pronouncements

In August 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 addresses how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230, Statement of Cash Flow, and Other Topics. ASU 2016-15 is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2017. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements.

In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting. The amendments in this updated guidance include changes to simplify the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This guidance is effective for fiscal years beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is permitted. The Company is in the process of evaluating the potential impacts of this new guidance on its consolidated financial statements.

In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606), Principal versus Agent Considerations (Reporting Revenue Gross versus Net). This update provides guidance on recording revenue on a gross basis versus a net basis based on the determination of whether an entity is a principal or an agent when another party is involved in providing goods or services to a customer. The amendments in this update affect the guidance in ASU No. 2014-09 and are effective in the same timeframe as ASU No. 2014-09 as discussed below.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The core principal of the guidance is that an entity should recognize assets and liabilities arising from a lease for both financing and operating leases, along with additional qualitative and quantitative disclosures. The standard will be effective for fiscal years beginning after December 15, 2018, including interim periods within such fiscal years. Early adoption is permitted. The guidance is to be applied using a modified retrospective transition method with the option to elect a package of practical expedients. The Company is currently evaluating the impact of the adoption of this accounting standard update on its internal processes, operating results and financial reporting. The impact is currently not known or reasonably estimable.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which completes the joint effort by the FASB and the International Accounting Standards Board to clarify the principles for recognizing revenue and improve financial reporting by creating common revenue recognition guidance for U.S. generally accepted accounting principles ("GAAP") and International Financial Reporting Standards ("IFRS"). ASU 2014-09 provides enhancements to the quality and consistency of how revenue is reported while also improving comparability in the financial statements of companies reporting using IFRS and GAAP. The core principle of this update is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB finalized a one-year deferral of the effective date of the new revenue recognition standard. The new standard will become effective for Ply Gem beginning with the first quarter of 2018 and can be adopted either retrospectively to each prior reporting period presented or as a cumulative effect adjustment as of the date of adoption. The method of adoption has not been determined yet by the Company. The Company is currently reviewing the revised guidance and assessing the potential impact on the consolidated financial statements.

GOODWILL

Goodwill [Abstract]

GOODWILL

The Company records the excess of the fair value of the acquisition consideration over the net tangible and intangible assets of acquired companies as goodwill.  The Company performs an annual test for goodwill impairment at the November month end each year and also at any other date when events or changes in circumstances indicate that the carrying value of these assets may exceed their fair value.  The Company has defined its reporting units and performs the impairment testing of goodwill at the operating segment level.  The Company has two reporting units: (1) Siding, Fencing and Stone and (2) Windows and Doors.  Separate valuations are performed for each of these reporting units in order to test for impairment.    

The Company uses the two-step method to determine goodwill impairment.  If the carrying amount of a reporting unit exceeds its fair value (“Step One”), the Company measures the possible goodwill impairment based upon a hypothetical allocation of the fair value estimate of the reporting unit to all of the underlying assets and liabilities of the reporting unit, including previously unrecognized intangible assets (“Step Two”).  The excess of the reporting unit’s fair value over the amounts assigned to its assets and liabilities is the implied fair value of goodwill.  An impairment loss is recognized to the extent that a reporting unit’s recorded goodwill exceeds the implied fair value of goodwill. The Company has elected not to utilize the qualitative Step Zero impairment assessment. There was no goodwill impairment for the year ended December 31, 2015 and no impairment indicators which would trigger an interim impairment test during the three and nine months ended October 1, 2016. However, the Company will continue to evaluate goodwill during future periods and future declines in the residential housing and repair and remodeling markets or the Company's market capitalization could result in goodwill impairments.  

To determine the fair value of its reporting units, the Company equally considers both the income and market valuation methodologies.  The income valuation methodology uses the fair value of the cash flows that the reporting unit can be expected to generate in the future. This method requires management to project revenues, operating expenses, working capital investment, capital spending and cash flows for the reporting unit over a multi-year period as well as determine the weighted average cost of capital to be used as the discount rate.  The Company also utilizes the market valuation method to estimate the fair value of the reporting units by utilizing comparable public company multiples.  These comparable public company multiples are then applied to the reporting unit’s financial performance.  The market approach is more volatile as an indicator of fair value as compared to the income approach as internal forecasts and projections have historically been more stable.  Since each approach has its merits, the Company equally weights the approaches to balance the internal and external factors affecting the Company’s fair value.

The Company’s fair value estimates of its reporting units and goodwill are sensitive to a number of assumptions including discount rates, cash flow projections, operating margins, and comparable market multiples.  In order to accurately forecast future cash flows, the Company estimates single family housing starts and the repair and remodeling market's growth rates.  However, there is no assurance that: (1) valuation multiples will not decline, (2) discount rates will not increase, or (3) the earnings, book values or projected earnings and cash flows of the Company's reporting units will not decline.

2015 Debt Transaction

On November 5, 2015, Ply Gem Industries entered into a second amended and restated ABL Facility. Among other things, the second amended and restated ABL Facility: (i) increased the overall facility to $350.0 million, (ii) provided an accordion feature of $50.0 million, and (iii) established the applicable margin for borrowings under the ABL Facility to a range of 1.25% to 2.00% for Eurodollar rate loans, depending on availability. All outstanding loans under the second amended and restated ABL Facility are due and payable in full on November 5, 2020.

6.50% Senior Notes due 2022

On January 30, 2014, Ply Gem Industries issued $500.0 million aggregate principal amount of 6.50% Senior Notes due 2022 (the "6.50% Senior Notes") at par. On September 19, 2014, Ply Gem Industries issued an additional $150.0 million aggregate principal amount of 6.50% Senior Notes at an issue price of 93.25%. Interest accrues at 6.50% per annum and is paid semi-annually on February 1 and August 1 of each year. All issued and outstanding 6.50% Senior Notes are registered under the Securities Act. The 6.50% Senior Notes will mature on February 1, 2022.

Prior to February 1, 2017, Ply Gem Industries may redeem up to 40% of aggregate principal amount of the 6.50% Senior Notes with the net cash proceeds from certain equity offerings at a redemption price equal to 106.50% of the aggregate principal amount of the 6.50% Senior Notes to be redeemed, plus accrued and unpaid interest, if any, provided that at least 50% of the aggregate principal amount of the 6.50% Senior Notes remains outstanding after the redemption. Prior to February 1, 2017, Ply Gem Industries may redeem the 6.50% Senior Notes, in whole or in part, at a redemption price equal to 100% of the principal amount plus a “make-whole” premium plus accrued and unpaid interest, if any. At any time on or after February 1, 2017, Ply Gem Industries may redeem the 6.50% Senior Notes, in whole or in part, at declining redemption prices set forth in the indenture governing the 6.50% Senior Notes plus, in each case, accrued and unpaid interest, if any, to the redemption date. The effective interest rate for the 6.50% Senior Notes is 8.39% after considering each of the different interest expense components of this instrument, including the coupon payment and the deferred debt issuance costs.

The 6.50% Senior Notes are fully and unconditionally and jointly and severally guaranteed on a senior unsecured basis by Ply Gem Holdings and all of the wholly-owned domestic subsidiaries of Ply Gem Industries (the “Guarantors”).  The indenture governing the 6.50% Senior Notes contains certain covenants that limit the ability of Ply Gem Industries and its restricted subsidiaries to incur additional indebtedness, pay dividends or make other distributions or repurchase or redeem their stock, make loans and investments, sell assets, incur certain liens, enter into agreements restricting their ability to pay dividends, enter into transactions with affiliates, and consolidate, merge or sell assets.  In particular, Ply Gem Industries and its restricted subsidiaries may not incur additional debt (other than permitted debt (as defined in the indenture) in limited circumstances) unless, after giving effect to such incurrence, the consolidated interest coverage ratio of Ply Gem Industries would be at least 2.00 to 1.00.  

In the absence of satisfying the consolidated interest coverage ratio test, Ply Gem Industries and its restricted subsidiaries may only incur additional debt under certain circumstances, including, but not limited to, debt under credit facilities (as defined in the indenture) (x) in an amount not to exceed the greater of (a) $350.0 million and (b) the borrowing base (as defined in the indenture) and (y) in an amount not to exceed the greater of (A) $575.0 million and (B) the aggregate amount of indebtedness (as defined in the indenture) that would cause the consolidated secured debt ratio (as defined in the indenture) to be equal to 4.00 to 1.00; purchase money indebtedness in an aggregate amount not to exceed the greater of (x) $35.0 million and (y) 10% of consolidated net tangible assets (as defined in the indenture) at any one time outstanding; debt of foreign subsidiaries in an aggregate amount not to exceed the greater of (x) $60.0 million and (y) 15% of consolidated net tangible assets (as defined in the indenture) at any one time outstanding; debt pursuant to a general basket in an aggregate amount at any one time outstanding not to exceed the greater of (x) $75.0 million and (y) 20% of consolidated net tangible assets; and the refinancing of debt under certain circumstances.

Term Loan Facility due 2021

On January 30, 2014, Ply Gem Industries entered into a credit agreement governing the terms of its $430.0 million Term Loan Facility. Ply Gem Industries originally borrowed $430.0 million under the Term Loan Facility on January 30, 2014, with an original discount of approximately $2.2 million, yielding proceeds of approximately $427.9 million. The Term Loan Facility will mature on January 30, 2021. The Term Loan Facility requires scheduled quarterly payments in an aggregate annual amount equal to 1.00% of the original aggregate principal amount of the Term Loan Facility with the balance due at maturity. Interest on outstanding borrowings under the Term Loan Facility is paid quarterly.

Borrowings under the Term Loan Facility bear interest at a rate equal to, at Ply Gem Industries’ option, either (a) a base rate determined by reference to the highest of (i) the prime rate of the administrative agent under the credit agreement, (ii) the federal funds rate plus 0.50% and (iii) the adjusted LIBO rate for a one-month interest period plus 1.00% or (b) a LIBO rate determined by reference to the cost of funds for eurocurrency deposits in dollars for the interest period relevant to such borrowing, adjusted for certain additional costs, subject to a 1.00% floor, plus, in each case, an applicable margin of 3.00% for any eurocurrency loan and 2.00% for any alternate base rate loan. As of October 1, 2016, the Company's interest rate on the Term Loan Facility was 4.00%. The effective interest rate for the Term Loan is 7.38% after considering each of the different interest expense components of this instrument, including the coupon payment, the deferred debt issuance costs and the original issue discount.

The Term Loan Facility allows Ply Gem Industries to request one or more incremental term loan facilities in an aggregate amount not to exceed the greater of (x) $140.0 million and (y) an amount such that Ply Gem Industries’ consolidated senior secured debt ratio (as defined in the credit agreement), on a pro forma basis, does not exceed 3.75 to 1.00, in each case, subject to certain conditions and receipt of commitments by existing or additional financial institutions or institutional lenders.

The Term Loan Facility requires Ply Gem Industries to prepay outstanding term loans, subject to certain exceptions, with: (i) 50% (which percentage will be reduced to 25% if our consolidated senior secured debt ratio is equal or less than 2.50 to 1.00 but greater than 2.00 to 1.00 and to 0% if our consolidated senior secured debt ratio is equal to or less than 2.00 to 1.00) of our annual excess cash flow (as defined in the credit agreement), to the extent such excess cash flow exceeds $15.0 million; (ii) 100% of the net cash proceeds of certain non-ordinary course asset sales or certain insurance and condemnation proceeds, in each case subject to certain exceptions and reinvestment rights; and (iii) 100% of the net cash proceeds of certain issuances of debt, other than proceeds from debt permitted under the Term Loan Facility. Ply Gem Industries may voluntarily repay outstanding loans under the Term Loan Facility at any time without premium or penalty, other than customary “breakage” costs with respect to LIBOR loans. As of and for the year ended December 31, 2015, the Company's consolidated senior secured debt ratio was 1.97 and as a result no excess cash flow payment under the Term Loan Facility was required. However, the Company elected on March 10, 2016 and August 4, 2016 to voluntarily prepay $30.0 million on each date on the Term Loan Facility to reduce its outstanding indebtedness. The Company further elected on November 4, 2016 to voluntarily pay an additional $100.0 million on the Term Loan Facility to further reduce its outstanding indebtedness bringing our cumulative voluntary 2016 Term Loan Facility payments to $160.0 million.

The Term Loan Facility is secured on a first-priority lien basis by the stock of Ply Gem Industries and by substantially all of the assets (other than the assets securing the obligations under the ABL Facility, which primarily consist of accounts receivable, inventory, cash, deposit accounts, securities accounts, chattel paper, contract rights, instruments, documents related thereto and proceeds of the foregoing) of Ply Gem Industries and the Guarantors that are subsidiaries of Ply Gem Industries and on a second-priority lien basis by the assets that secure the ABL Facility.

The Term Loan Facility includes negative covenants, subject to certain exceptions, that are substantially the same as the negative covenants in the 6.50% Senior Notes but does not contain any restrictive financial covenants. The Term Loan Facility also restricts the ability of Ply Gem Industries’ subsidiaries to enter into agreements restricting their ability to grant liens to secure the Term Loan Facility and contains a restriction on changes in fiscal year.

Senior Secured Asset Based Revolving Credit Facility due 2020

On November 5, 2015, Ply Gem Holdings, Inc., Ply Gem Industries, Inc., Gienow Canada Inc., and Mitten Inc. (together with Gienow, the “Canadian Borrowers”) entered into a second amended and restated credit agreement governing the ABL Facility. Among other things, the second amendment and restatement of the credit agreement governing the ABL Facility: (i) increased the overall facility to $350.0 million from $300.0 million, (ii) established an accordion feature of $50.0 million, (iii) reduced the applicable margin for borrowings under the ABL Facility to a range from 1.25% to 2.00% for Eurodollar rate loans, depending on availability, and (iv) extended the maturity until November 5, 2020. Under the ABL Facility, $300.0 million is available to Ply Gem Industries and $50.0 million is available to the Canadian Borrowers. The following summary describes the ABL Facility after giving effect to the second amendment and restatement. As a result of the November 2015 ABL Facility amendment in which the loan syndication consisted of previous members who either maintained or increased their position as well as new syndication members, the Company capitalized new debt issuance costs of $1.5 million and will amortize these costs through 2020.

Borrowings under the ABL Facility bear interest at a rate per annum equal to, at Ply Gem Industries’ option, either (a) a base rate determined by reference to the higher of (1) the corporate base rate of the administrative agent under the ABL Facility and (2) the federal funds rate plus 0.5% or (b) a Eurodollar rate determined by reference to the costs of funds for U.S. dollar deposits for the interest period relevant to such borrowing adjusted for certain additional costs, in each case plus an applicable margin.  The initial applicable margin for borrowings under the ABL Facility was 0.50% for base rate loans and 1.50% for Eurodollar rate loans.  The applicable margin for borrowings under the ABL Facility is subject to step ups and step downs based on average excess availability under the ABL Facility.  Swingline loans bear interest at a rate per annum equal to the base rate plus the applicable margin.

In addition to paying interest on outstanding principal under the ABL Facility, Ply Gem Industries is required to pay a commitment fee in respect of the unutilized commitments thereunder, which fee will be determined based on utilization of the ABL Facility (increasing when utilization is low and decreasing when utilization is high) multiplied by a commitment fee rate determined by reference to average excess availability under the ABL Facility. The commitment fee rate during any fiscal quarter is 0.375% when average excess availability is greater than $100.0 million for the preceding fiscal quarter and 0.25% when average availability is less than or equal to $100.0 million for the preceding fiscal quarter.  Ply Gem Industries must also pay customary letter of credit fees equal to the applicable margin on Eurodollar loans and agency fees.   As of October 1, 2016, the Company’s interest rate on the ABL Facility was approximately 1.88%.  The ABL Facility requires that if (a) excess availability is less than the greater of (x) 10.0% of the lower of the borrowing base and the aggregate commitments and (y) $25.0 million or (b) any event of default has occurred and is continuing, Ply Gem Industries must comply with a minimum fixed charge coverage ratio test of 1.0 to 1.0.  If the excess availability under the ABL Facility is less than the greater of (a) 12.5% of the lesser of the borrowing base and the aggregate commitments and (b) $30.0 million ($27.5 million for the months of January, February, March and April) for a period of 5 consecutive days or an event of default has occurred and is continuing, all cash from Ply Gem Industries material deposit accounts (including all concentration accounts) will be swept daily into a collection account controlled by the administrative agent under the ABL Facility and used to repay outstanding loans and cash collateralize letters of credit.

All obligations under the ABL Facility are unconditionally guaranteed by Ply Gem Holdings and substantially all of Ply Gem Industries’ existing and future, direct and indirect, wholly owned domestic subsidiaries.  All obligations under the ABL Facility, and the guarantees of those obligations, are secured, subject to certain exceptions, by substantially all of the assets of Ply Gem Industries and the guarantors, including a first-priority security interest in personal property consisting of accounts receivable, inventory, cash, deposit accounts, and certain related assets and proceeds of the foregoing and a second-priority security interest in, and mortgages on, substantially all of Ply Gem Industries’ and the Guarantors’ material owned real property and equipment and all assets that secure the Term Loan Facility on a first-priority basis.  In addition to being secured by the collateral securing the obligations of Ply Gem Industries under the domestic collateral package, the obligations of the Canadian Borrowers, which are borrowers under the Canadian sub-facility under the ABL Facility, are also secured by a first-priority security interest in substantially all of the assets of such Canadian subsidiaries, plus additional mortgages in Canada, and a pledge by Ply Gem Industries of the remaining 35% of the equity interests of the Canadian Borrowers pledged only to secure the Canadian sub-facility.

The ABL Facility contains certain covenants that limit Ply Gem Industries’ ability and the ability of Ply Gem Industries’ subsidiaries to incur additional indebtedness, pay dividends or make other distributions or repurchase or redeem their stock, make loans and investments, sell assets, incur certain liens, enter into transactions with affiliates, and consolidate, merge or sell assets.  

As of October 1, 2016, Ply Gem Industries had approximately $339.4 million of contractual availability and approximately $274.0 million of borrowing base availability under the ABL Facility, reflecting $0.0 million of borrowings outstanding and approximately $10.6 million of letters of credit and priority payables reserves.

Loss on debt modification or extinguishment

During both March and August 2016, the Company made voluntarily payments of $30.0 million on the Term Loan Facility to reduce its outstanding indebtedness as allowable under the terms of the Term Loan Facility totaling $60.0 million during 2016. The Company performed an analysis to determine the proper accounting treatment for each of these voluntary payments by evaluating the change in cash flows and determined that there were no changes in creditors as a result of the payments. Consequently, the Company recognized a loss on debt modification or extinguishment of approximately $2.3 million and $4.7 million for the three and nine months endedOctober 1, 2016, respectively, reflecting the proportionate write-off of the related debt discount and debt issuance costs associated with each $30.0 million payment, as summarized in the table below.

Indemnifications

In connection with the Ply Gem acquisition, in which Ply Gem Industries was acquired from Nortek, Inc. (“Nortek”) in February 2004, Nortek has agreed to indemnify the Company for certain liabilities as set forth in the stock purchase agreement governing the Ply Gem acquisition.  In the event Nortek is unable to satisfy amounts due under these indemnifications, the Company would be liable.  The Company believes that Nortek has the financial capacity to honor its indemnification obligations and therefore does not anticipate incurring any losses related to liabilities indemnified by Nortek under the stock purchase agreement.  A receivable related to this indemnification has been recorded in other long-term assets of approximately $1.5 million and $1.8 million at October 1, 2016 and December 31, 2015, respectively.  As of October 1, 2016 and December 31, 2015, the Company has recorded liabilities related to these indemnifications of approximately $0.5 million and $0.5 million, respectively, in current liabilities and $1.0 million and $1.3 million, respectively, in long-term liabilities, consisting of the following:

(Amounts in thousands)	October 1, 2016		December 31, 2015
Product claim liabilities	$	138	$	138
Multi-employer pension plan withdrawal liability	823		960
Other	528		664
	$	1,489	$	1,762

Warranty claims

The Company sells a number of products and offers a number of warranties.  The specific terms and conditions of these warranties vary depending on the product sold.  The Company estimates the costs that may be incurred under their warranties and records a liability for such costs at the time of sale.  Factors that affect the Company’s warranty liabilities include the number of units sold, historical and anticipated rates of warranty claims, cost per claim and new product introduction.  The Company assesses the adequacy of the recorded warranty claims and adjusts the amounts as necessary.  As of October 1, 2016 and December 31, 2015, warranty liabilities of approximately $19.4 million and $16.6 million, respectively, have been recorded in current liabilities and approximately $57.4 million and $59.9 million, respectively, have been recorded in long term liabilities in the Company's condensed consolidated balance sheets.

Changes in the Company’s short-term and long-term warranty liabilities are as follows:

Environmental

The Company is subject to United States and Canadian federal, state, provincial and local laws and regulations relating to pollution and the protection of the environment, including those governing emissions to air, discharges to water, use, storage and transport of hazardous materials, storage, treatment and disposal of waste, remediation of contaminated sites, and protection of worker health and safety. From time to time, the Company's facilities are subject to investigation by governmental regulators. In addition, the Company has been identified as one of many potentially responsible parties for contamination present at certain offsite locations to which it or its predecessors are alleged to have sent hazardous materials for recycling or disposal. The Company may be held liable, or incur fines or penalties, in connection with such requirements or liabilities for, among other things, releases of hazardous substances occurring on or emanating from current or formerly owned or operated properties or any associated offsite disposal location, or for known or newly-discovered contamination at any of the Company's properties from activities conducted by us or previous occupants. The amount of any liability, fine or penalty may be material, and certain environmental laws impose strict, and under certain circumstances joint and several, liability for the cost of addressing releases of hazardous substances upon certain classes of persons, including site owners or operators and persons that disposed or arranged for the disposal of hazardous substances at contaminated sites.

MW Manufacturers Inc. (“MW”), a subsidiary of MWM Holding, Inc., entered into an Administrative Order on Consent (the “Consent Order”), effective September 12, 2011, with the United States Environmental Protection Agency (“EPA”), Region III, under Section 3008(h) of the Resource Conservation and Recovery Act ("RCRA"), with respect to its Rocky Mount, Virginia property.  During 2011, as part of the Consent Order, MW provided the EPA, among other things, a RCRA Facility Investigation Workplan (the “Workplan”) as well as a preliminary cost estimate of approximately $1.8 million for the predicted assessment, remediation and monitoring activities to be conducted pursuant to the Consent Order over the remediation period, which is currently estimated through 2023. During 2012, the EPA approved the Workplan, and MW is currently implementing the Workplan. The Company has recorded approximately $0.3 million of this environmental liability within current liabilities and approximately $1.2 million within other long-term liabilities in the Company’s condensed consolidated balance sheet at October 1, 2016 and December 31, 2015.  The Company will adjust this environmental remediation liability in future periods, if necessary, as further information develops or circumstances change.

Certain liabilities with respect to this contamination relate to the previous closure of an underground storage tank and were assumed by U.S. Industries, Inc., pursuant to its indemnity obligation under the stock purchase agreement dated August 11, 1995, whereby U.S. Industries, Inc. sold the stock of MW to FPI Acquisition Corp. (“Fenway Partners”). As the successor-in-interest of Fenway Partners, the Company is similarly indemnified by U.S. Industries, Inc. Notwithstanding this indemnity, however, under applicable Federal and State laws, MW, and the Company as its parent, could be held liable for all or part of the costs associated with the matter under certain circumstances. Moreover, the Company’s ability to seek indemnification from U.S. Industries, Inc. is limited by the terms and limits of the indemnity as well as the strength of U.S. Industries, Inc. is, however, limited by the terms and limits of the indemnity as well as the strength of U.S. Industries, Inc.’s financial condition, which could change in the future.  As of October 1, 2016, no recovery has been recognized on the Company’s condensed consolidated balance sheet, but the Company will actively pursue this indemnity in future periods and will recognize future recoveries in the period in which they become probable.

The State of Nebraska is investigating certain groundwater contamination in northern York, Nebraska, comprised primarily of volatile organic compounds (VOC) (predominantly trichloroethene (TCE)). In December 2013, the EPA announced its proposal to add this groundwater contamination site to the Superfund National Priorities List (NPL) after it was referred to the EPA by the State of Nebraska. Sampling was conducted at the Kroy Building Products, Inc. (“Kroy”) facility in York, Nebraska during the first quarter of 2010. In February 2015, the EPA sent a request for information pursuant to Section 104 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), and Kroy has responded to this request for information. Given the preliminary stage of this matter, the Company has not recorded a liability for this matter in its condensed consolidated balance sheet as of October 1, 2016. Alcan Aluminum Corporation (“Alcan”) has assumed the obligation to indemnify the Company with respect to certain liabilities for environmental contamination of the Kroy facility occurring prior to 1994. Notwithstanding this indemnity, however, under applicable Federal and State laws, Kroy, and Ply Gem as its parent, could be held liable for all or part of the costs associated with the matter under certain circumstances. Moreover, the ability of Kroy and Ply Gem to seek indemnification may be limited by the terms and limits of the indemnity as well as the strength of Alcan’s financial condition, which could change in the future.

The Company is currently involved in environmental proceedings involving Gienow Canada Inc. (f/k/a Ply Gem Canada, Inc.) and Alberta Environment (arising from subsurface contamination discovered at our Calgary, Alberta property) for which the Company has a $0.1 million liability included in its condensed consolidated balance sheet, and the Company may in the future be subject to environmental proceedings involving Thermal-Gard, Inc. (arising from groundwater contamination in Punxsutawney, Pennsylvania), Mastic Home Exteriors, Inc. (“MHE”) (relating to a closed landfill site in Sidney, Ohio as well as participating as a potentially responsible party in nine contaminated sites in Indiana, Ohio and South Carolina), and Simonton (relating to closed lagoons and certain contamination in Paris, Illinois as well as certain contamination associated with certain 7-Eleven convenience food stores). Under the stock purchase agreement governing the MHE acquisition, Alcoa Securities Corporation and Alcoa, Inc. are to indemnify the Company for certain environmental liabilities in excess of $2.5 million including liabilities relating to the landfill site in Sidney, Ohio and the nine contaminated sites in Indiana, Ohio and South Carolina. Under the stock purchase agreement governing the Simonton acquisition, Fortune Brands Windows & Doors, Inc., is to indemnify the Company for any environmental claims associated with the 7-Eleven convenience food stores. The Company's ability to seek indemnification or enforce these and other obligations is, however, limited by the strength of the financial condition of the indemnitor or responsible party, which could change in the future, as well as the terms and limits of any such indemnities or obligations.

Based on current information, the Company is not aware of any compliance obligations, claims, releases or investigations that will have a material adverse effect on our results of operations, cash flows or financial position except as otherwise disclosed in the Company's condensed consolidated financial statements. However, there can be no guarantee that previously known or newly-discovered matters or any inability to enforce our available indemnification rights against previous owners of the Company, its subsidiaries, or their businesses or properties will not result in material costs or liabilities. While the purchase agreements governing certain of our acquisitions provide that the sellers will indemnify us, subject to certain limitations, for certain environmental liabilities, our ability to seek indemnification from the respective sellers is limited by various factors, including the financial condition of the indemnitor or responsible party as well as by the terms and limits of such indemnities or obligations. As a result, there can be no assurance that we could receive any indemnification from the sellers, and any related environmental liabilities, costs or penalties could have a material adverse effect on our financial condition and results of operations.

Self-insured risks

The Company maintains a broad range of insurance policies which include general liability insurance coverage and workers compensation. These insurance policies protect the Company against a portion of the risk of loss from claims. However, the Company retains a portion of the overall risk for such claims through its self-insured per occurrence and aggregate retentions, deductibles, and claims in excess of available insurance policy limits. The Company's general liability insurance includes coverage for certain damages arising out of product design and manufacturing defects. The Company's insurance coverage is generally subject to a per occurrence retention.

The Company reserves for costs associated with claims, as well as incurred but not reported losses (“IBNR”), based on an outside actuarial analysis of its historical claims. These estimates make up a significant portion of the Company's liability and are subject to a high degree of uncertainty due to a variety of factors, including changes in type of claims, claims reporting and resolution patterns, frequency and timing of claims, third party recoveries, estimates of claim values, claims management expenses (including legal fees and expert fees), insurance industry practices, the regulatory environment, and legal precedent. Adjustments to estimated reserves are recorded in the period in which the change in estimate occurs.

Litigation

During the past several years, the Company incurred increased litigation expense primarily related to the claims discussed below. The Company believes it has valid defenses to the outstanding claims discussed below and will vigorously defend all such claims; however, litigation is subject to many uncertainties and there cannot be any assurance that the Company will ultimately prevail or, in the event of an unfavorable outcome or settlement of litigation, that the ultimate liability would not be material and would not have a material adverse effect on the business, results of operations, cash flows or financial position of the Company.

In John Gulbankian v. MW Manufacturers, Inc. (“Gulbankian”), a purported class action filed in March 2010 in the United States District Court for the District of Massachusetts, plaintiffs, on behalf of themselves and all others similarly situated, alleged damages as a result of the defective design and manufacture of certain MW vinyl clad windows. In Eric Hartshorn and Bethany Perry v. MW Manufacturers, Inc. (“Hartshorn”), a purported class action filed in July 2012 in the District Court, plaintiffs, on behalf of themselves and all others similarly situated, alleged damages as a result of the defective design and manufacture of certain MW vinyl clad windows. On April 22, 2014, plaintiffs in both the Gulbankian and Hartshorn cases filed a Consolidated Amended Class Action Complaint, making similar claims against all MW vinyl clad windows.

MW entered into a settlement agreement with plaintiffs as of April 18, 2014 to settle both the Gulbankian and Hartshorn cases on a nationwide basis (the “Vinyl Clad Settlement Agreement”). The Vinyl Clad Settlement Agreement provides that this settlement applies to any and all MW vinyl clad windows manufactured from January 1, 1987 through May 23, 2014, and provides for a cash payment for eligible consumers submitting qualified claims showing, among other requirements, certain damage to their MW vinyl clad windows. The period for submitting qualified claims is the later of: (i) May 28, 2016, or (ii) the last day of the warranty period for the applicable window. On December 29, 2014, the District Court granted final approval of this settlement, as well as MW’s payment of attorneys' fees and costs to plaintiffs' counsel in the amount of $2.5 million, issuing a Final Approval Order, Final Judgment, and Order of Dismissal with Prejudice (the "Final Approval Order"). A notice of appeal of the Final Approval Order (the “Appeal”) was given by certain objectors to the settlement, and on May 6, 2015, MW entered into a settlement agreement with, among others, the objectors to fully and finally resolve their claims, including the dismissal of Karl Memari v. Ply Gem Prime Holdings, Inc. et al., another lawsuit seeking class certification with respect to MW's vinyl clad windows, making the Vinyl Clad Settlement Agreement final and binding on the parties. The Company and MW deny all liability in the settlements with respect to the facts and claims alleged. The Company, however, is aware of the substantial burden, expense, inconvenience and distraction of continued litigation, and therefore agreed to settle these matters.

As a result of the Vinyl Clad Settlement Agreement, the Company recognized a $5.0 million expense during the year ended December 31, 2014 within selling, general, and administrative expenses in the Company’s consolidated statement of operations and comprehensive income (loss) in the Company's Windows and Doors segment. It is possible that the Company may incur costs in excess of the recorded amounts; however, the Company currently expects that the total net cost will not exceed $5.0 million. As of October 1, 2016, approximately $1.4 million of this liability is currently outstanding with $0.7 million as a current liability within accrued expenses and $0.7 million as a noncurrent liability within other long-term liabilities in the Company’s condensed consolidated balance sheet.

In Anthony Pagliaroni et al. v. Mastic Home Exteriors, Inc. and Deceuninck North America, LLC, a purported class action filed in January 2012 in the United States District Court for the District of Massachusetts, plaintiffs, on behalf of themselves and all others similarly situated, allege damages as a result of the defective design and manufacture of Oasis composite deck and railing, which was manufactured by Deceuninck North America, LLC (“Deceuninck”) and sold by Mastic Home Exteriors, Inc. (“MHE”). The plaintiffs seek a variety of relief, including (i) economic and compensatory damages, (ii) treble damages, (iii) punitive damages, and (iv) attorneys' fees and costs of litigation. The damages sought in this action have not yet been quantified. The hearing regarding plaintiffs’ motion for class certification was held on March 10, 2015, and the District Court denied plaintiffs’ motion for class certification on September 22, 2015. On October, 6, 2015, plaintiffs filed a petition for interlocutory appeal of the denial of class certification to the U.S. Court of Appeals for the First Circuit, and on April 12, 2016, the Court of Appeals denied this petition for appeal. Deceuninck, as the manufacturer of Oasis deck and railing, has agreed to indemnify MHE for certain liabilities related to this claim pursuant to the sales and distribution agreement, as amended, between Deceuninck and MHE. MHE's ability to seek indemnification from Deceuninck is, however, limited by the terms and limits of the indemnity as well as the strength of Deceuninck's financial condition, which could change in the future.

In rePly Gem Holdings, Inc. Securities Litigation isa purported federal securities class action filed on May 19, 2014 in the United States District Court for the Southern District of New York against Ply Gem Holdings, Inc., several of its directors and officers, and the underwriters associated with the Company’s initial public offering ("IPO"). It is filed on behalf of all persons or entities, other than the defendants, who purchased the common shares of the Company pursuant and/or traceable to the Company’s IPO and seeks remedies under Sections 11 and 15 of the Securities Act of 1933, alleging that the Company’s Form S-1 registration statement was negligently prepared and materially inaccurate, containing untrue statements of material fact and omitting material information which was required to be disclosed. The plaintiffs seek a variety of relief, including (i) damages together with interest thereon and (ii) attorneys’ fees and costs of litigation. On October 14, 2014, Strathclyde Pension Fund was certified as lead plaintiff, and class counsel was appointed. On February 13, 2015, the defendants filed their motion to dismiss the complaint. On September 29, 2015, the District Court granted defendants’ motion to dismiss, but ruled that plaintiff could file an amended complaint. On November 6, 2015, plaintiff filed an amended complaint, and on January 13, 2016, the defendants filed their motion to dismiss this amended complaint. On September 23, 2016, the District Court granted in part and denied in part this motion to dismiss. The damages sought in this action have not yet been quantified. Pursuant to the Underwriting Agreement, dated May 22, 2013, entered into in connection with the IPO, the Company has agreed to reimburse the underwriters for the legal fees and other expenses reasonably incurred by the underwriters’ law firm in its representation of the underwriters in connection with this matter. Pursuant to Indemnification Agreements, dated as of May 22, 2013, between the Company and each of the directors and officers named in this action, the Company has agreed to assume the defense of such directors and officers. We believe the purported federal securities class action is without merit and will vigorously defend the lawsuit.

In Raul Carrillo-Hueso and Chec Xiong v. Ply Gem Industries, Inc. and Ply Gem Pacific Windows Corporation, a purported class action filed on November 25, 2015 in the Superior Court of the State of California, County of Alameda, plaintiffs, on behalf of themselves and all others similarly situated, allege damages as a result of, among other things, the defendants’ failure to provide (i) statutorily required meal breaks at the Sacramento, California facility, (ii) accurate wage statements to employees in California, and (iii) all wages due on termination in California. The plaintiffs seek a variety of relief, including (i) economic and compensatory damages, (ii) statutory damages, (iii) penalties, (iv) pre- and post-judgment interest, and (v) attorneys' fees and costs of litigation. The damages sought in this action have not yet been quantified.

In Tina Morgan v. Ply Gem Industries, Inc. and Simonton Industries, Inc., a purported class action filed on December 11, 2015 in the Superior Court of the State of California, County of Solano, plaintiff, on behalf of herself and all others similarly situated, alleges damages as a result of, among other things, the defendants’ failure at the Vacaville, California facility to (i) pay overtime wages, (ii) provide statutorily required meal breaks, (iii) provide accurate wage statements, and (iv) pay all wages owed upon termination. The plaintiff seeks a variety of relief, including (i) economic and compensatory damages, (ii) statutory damages, (iii) penalties, (iv) pre- and post-judgment interest, and (v) attorneys' fees and costs of litigation. The damages sought in this action have not yet been quantified.

In Kiefer et al. v. Simonton Building Products, LLC et al., a purported class action filed on October 17, 2016 in the United States District Court for the District of Minnesota, plaintiffs, on behalf of themselves and all others similarly situated, allege damages as a result of, among other things, the defective design and manufacture of certain Simonton windows containing two-pane insulating glass units. The plaintiffs seek a variety of relief, including (i) economic and compensatory damages, (ii) punitive or other exemplary damages, (iii) pre- and post-judgment interest, and (iv) attorneys' fees and costs of litigation. The damages sought in this action have not yet been quantified.

Other contingencies

The Company is subject to other contingencies, including legal proceedings and claims arising out of its operations and businesses that cover a wide range of matters, including, among others, environmental, contract, employment, intellectual property, securities, personal injury, property damage, product liability, warranty, and modification, adjustment or replacement of component parts or units sold, which may include product recalls.  Product liability, environmental and other legal proceedings also include matters with respect to businesses previously owned.  The Company has used various substances in their products and manufacturing operations, which have been or may be deemed to be hazardous or dangerous, and the extent of its potential liability, if any, under environmental, product liability and workers’ compensation statutes, rules, regulations and case law is unclear.  Further, due to the lack of adequate information and the potential impact of present regulations and any future regulations, there are certain circumstances in which no range of potential exposure may be reasonably estimated.  Also, it is not possible to ascertain the ultimate legal and financial liability with respect to certain contingent liabilities, including lawsuits, and therefore no such estimate has been made as of October 1, 2016.

INCOME TAXES

Income Tax Disclosure [Abstract]

INCOME TAXES

 INCOME TAXES

Effective tax rate

Under FASB Accounting Standards Codification 740-270, Income Taxes - Interim Reporting, each interim period is considered an integral part of the annual period and tax expense is measured using an estimated annual effective rate. Estimates of the annual effective tax rate at the end of interim periods are, of necessity, based on evaluation of possible future events and transactions and may be subject to subsequent refinement or revision. The Company calculates its quarterly tax provision consistent with the guidance provided by ASC 740-270, whereby the Company forecasts its estimated annual effective tax rate then applies that rate to its year-to-date pre-tax book income (loss). In addition, we exclude jurisdictions with a projected loss for the year or the year-to-date loss where we cannot recognize a tax benefit from our estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter, based upon the mix and timing of actual earnings versus annual projections. In addition to the tax resulting from applying the estimated annual effective tax rate to pre-tax income (loss), the Company includes certain items treated as discrete events to arrive at an estimated effective tax rate. Future changes in the forecasted annual income (loss) projections, tax rate changes, or discrete tax items could result in significant adjustments to quarterly income tax expense (benefit) in future periods in accordance with ASC 740-270.

For the nine months endedOctober 1, 2016, the Company's estimated annual effective income tax rate was approximately 3.8%, which varied from the statutory rate primarily due to state income tax expense, valuation allowances, and foreign income taxes. The effective tax rate including discrete items, primarily related to the valuation allowance release, was 240.3% for the nine months ended October 1, 2016. The tax benefit for the three months ended October 1, 2016 was approximately $49.1 million, and the tax expense for the three months ended October 3, 2015 was approximately $2.1 million. The tax benefit for the nine months ended October 1, 2016 was approximately $48.6 million, and the tax benefit for the nine months ended October 3, 2015 was approximately $1.8 million. The tax benefit increased during the three and nine months ended October 1, 2016 from the valuation allowance release for federal and certain state jurisdictions, partially offset by state income tax, remaining valuation allowances, and foreign income taxes.

Valuation allowance

During the three and nine months ended October 1, 2016, the Company determined that a valuation allowance was no longer required against its federal deferred tax assets and a portion of its state deferred tax assets. Therefore, the Company released approximately $50.1 million of its valuation allowance since positive evidence outweighed negative evidence thereby allowing the Company to achieve the “more likely than not” realization threshold. As of October 1, 2016, the Company was no longer in a three-year cumulative pre-tax loss position due to the significant improvement in the Company’s profitability from the housing market recovery. The housing market has experienced steady improvement from a demand perspective over the last several years which has benefited the Company’s financial performance and profitability for both new construction and repair and remodeling reflected in the Company’s net sales and earnings growth. This annual financial improvement was further evidenced by the Company continuing to have net sales and profitability growth in the Company’s second and third quarters which are traditionally the Company’s strongest financial quarters based on seasonality. Finally, the consensus expectation and outlook for both new construction and repair and remodeling both show positive growth rates over the next few years which result in future forecasted profitability for the Company. Based on the preponderance of these positive factors, the valuation allowance was released during the three and nine months ended October 1, 2016. The valuation allowance release is reflected within our provision (benefit) for income taxes in the accompanying condensed consolidated statement of operations and comprehensive income (loss) during the three and nine months ended October 1, 2016.

The Company determined that when a change in valuation allowance is recognized in an interim period, a portion of the valuation allowance to be released must be allocated to the remaining interim periods. Accordingly, a portion of the remaining valuation allowance, approximately $16.8 million, will release for the Company in the fourth quarter of 2016. The Company still remains in a valuation allowance position against its deferred tax assets for certain state and Canadian jurisdictions as it is currently deemed "more likely than not" that the benefit of such net tax assets will not be utilized as the Company continues to be in a three-year cumulative loss position for these states and Canadian jurisdictions. The Company will continue to monitor the positive and negative factors for these jurisdictions and make further changes to the valuation allowances as necessary.

Tax uncertainties

Despite the Company’s belief that its tax return positions are consistent with applicable tax laws, the Company believes that certain positions could be challenged by taxing authorities. The Company’s tax reserves reflect the difference between the tax benefit claimed on tax returns and the amount recognized in the condensed consolidated financial statements. These reserves have been established based on management’s assessment as to potential exposure attributable to permanent differences and interest and penalties applicable to both permanent and temporary differences. The tax reserves are reviewed periodically and adjusted in light of changing facts and circumstances, such as progress of tax audits, lapse of applicable statutes of limitations and changes in tax law. Certain income tax returns are currently under examination by various taxing authorities. During the nine months endedOctober 1, 2016, approximately $0.2 million of interest expense was recorded on the remaining uncertain tax positions. The Company made no other adjustments to the tax reserves or penalties during the nine months endedOctober 1, 2016.

The liability for unrecognized tax benefits as of October 1, 2016 was approximately $3.1 million and is recorded in other long-term liabilities in the accompanying condensed consolidated balance sheet. The corresponding amount of gross unrecognized tax benefit was approximately $15.9 million. The difference between the total unrecognized tax benefits and the amount of the liability for unrecognized tax benefits represents unrecognized tax benefits that have been netted against deferred tax assets related to net operating losses in accordance with ASC 740 in addition to accrued penalties and interest.

Tax Receivable Agreement

On May 22, 2013, the Company entered into a Tax Receivable Agreement (the “Tax Receivable Agreement”) with PG ITR Holdco, L.P. (the “Tax Receivable Entity”). The Tax Receivable Agreement generally provides for the payment by the Company to the Tax Receivable Entity of 85% of the amount of cash savings, if any, in U.S. federal, state and local income tax that the Company actually realizes in periods ending after the IPO as a result of (i) NOL carryovers from periods (or portions thereof) ending before January 1, 2013, (ii) deductible expenses attributable to the transactions related to the IPO and (iii) deductions related to imputed interest deemed to be paid by the Company as a result of or attributable to payments under the Tax Receivable Agreement. The term of the Tax Receivable Agreement will continue until all such benefits have been utilized or expired. The Company will retain the benefit of the remaining 15% of these tax savings. The Tax Receivable Agreement will obligate the Company to make payments to the Tax Receivable Entity generally equal to 85% of the applicable cash savings that is actually realized as a result of utilizing NOL carryovers once the tax returns are filed for that respective tax year.

The Company estimates that the total anticipated amount of future payments under the Tax Receivable Agreement could be up to approximately $89.0 million assuming no material changes in the relevant tax law, that the Company earns sufficient taxable income to utilize the net operating loss carry forwards, and that utilization of such tax attributes is not subject to limitation under Section 382 of the Internal Revenue Code of 1986, as amended (the "Code") as the result of an “ownership change”. It is possible that future transactions or events or changes in estimates could increase or decrease the actual tax benefits realized from these tax attributes and the corresponding Tax Receivable Agreement payments and liability.

Since the inception of the TRA liability with the Company’s 2013 initial public offering, the Company has had a full valuation allowance on its federal deferred tax assets and a partial valuation allowance on certain state and Canadian jurisdictions. As a result of the Company’s tax valuation allowance position for federal and state purposes, the Company calculated the TRA liability considering (i) current year taxable income only (due to the uncertainty of future taxable income associated with the Company’s cumulative loss position) and (ii) future income due to the expected reversals of deferred tax liabilities. During the three and nine months ended October 1, 2016, the Company released its valuation allowance on its federal deferred tax assets and certain state deferred tax assets for approximately $50.1 million due to positive factors outweighing negative evidence and specifically, the Company no longer being in a cumulative loss position. This release thereby eliminated any uncertainty as to future taxable income. Consequently, for purposes of calculating the Company’s TRA liability it was able to utilize future forecasts of taxable income beyond the 2016 tax year to determine the liability as of October 1, 2016. As a result of including future taxable income beyond 2016, the Company recognized a $42.2 million increase to the TRA liability during the three months ended October 1, 2016 bringing the total TRA liability to $84.4 million as of October 1, 2016. This amount represents the originally anticipated TRA liability at the initial public offering date with approximately $4.4 million remaining to be expensed through operations for state purposes as the Company remains in a tax valuation allowance position as of October 1, 2016 for certain states. This remaining liability will be recognized as the state valuation allowances are released in future years.

As of October 1, 2016 and December 31, 2015, the Company had a long-term liability of approximately $79.9 million and $20.8 million, respectively, and a current liability of $4.5 million and $3.0 million, respectively, for the amount due pursuant to the Tax Receivable Agreement. The Company recognized a $42.2 million expense and $1.7 million benefit for this liability during the three months ended October 1, 2016 and October 3, 2015, respectively. The Company recognized a $60.6 million and $13.5 million expense for this liability during the nine months ended October 1, 2016 and October 3, 2015, respectively.

Other

As of October 1, 2016, the Company has not established U.S. deferred taxes on unremitted earnings of the Company’s foreign subsidiaries. Notwithstanding the provisions within the American Jobs Creation Act of 2004, the Company continues to consider these amounts to be permanently reinvested.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

9 Months Ended

Oct. 01, 2016

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of Ply Gem Holdings, Inc. and its subsidiaries (referred to herein as “Ply Gem Holdings”, “Ply Gem”, the “Company”, “we”, “us”, or “our”) have been prepared in accordance with U.S. generally accepted accounting principles as described in the consolidated financial statements and related notes included in our 2015 Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 14, 2016.  These statements do not include all of the information and footnotes required by U.S. generally accepted accounting principles and should be read in conjunction with our 2015 Annual Report on Form 10-K.  In management’s opinion, all normal and recurring adjustments considered necessary for a fair presentation have been included.  Operating results for the period from January 1, 2016 through October 1, 2016 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016.

The condensed consolidated balance sheet at December 31, 2015 has been derived from the audited consolidated financial statements of Ply Gem Holdings at that date, but does not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements.

The Company’s fiscal quarters are based on periods ending on the Saturday of the last week in the quarter.  Therefore, the financial results of certain fiscal quarters will not be comparable to the prior and subsequent fiscal quarters.  The accompanying financial statements include the Company’s condensed consolidated statements of operations and comprehensive income (loss) for the three and nine months ended October 1, 2016 and October 3, 2015, the condensed consolidated statements of cash flows for the nine months endedOctober 1, 2016 and October 3, 2015, and the condensed consolidated balance sheets as of October 1, 2016 and December 31, 2015.

Ply Gem is a diversified manufacturer of residential and commercial building products, which are sold primarily in the United States and Canada, and include a wide variety of products for the residential and commercial construction, the do-it-yourself and the professional remodeling and renovation markets.  The demand for the Company’s products is seasonal, particularly in the Northeast and Midwest regions of the United States and Canada where inclement weather during the winter months usually reduces the level of building and remodeling activity in both the home repair and remodeling and new home construction sectors.  The Company’s sales are usually lower during the first and fourth quarters.

To a significant extent our performance is dependent upon the levels of home repair and remodeling and new home construction spending, all of which are affected by such factors as interest rates, inflation, consumer confidence, unemployment, and availability of consumer credit.

Principles of Consolidation

Principles of Consolidation

The condensed consolidated financial statements include the accounts of Ply Gem Holdings and its subsidiaries, all of which are wholly owned.  All intercompany accounts and transactions have been eliminated.

Reclassifications [Text Block]

Reclassifications

Due to the adoption of ASU No. 2015-03, Interest-Imputation of Interest, certain balance sheet amounts in the prior fiscal year have been reclassified to conform to the presentation adopted in the current fiscal year, with no effect on net income, accumulated deficit, or net cash provided by (used in) operating, investing, and financing activities.

Accounting Policies and Use of Estimates

Accounting Policies and Use of Estimates

The preparation of these condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles involves estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of income and expense during the reporting periods.  Certain of the Company’s accounting policies require the application of judgment in selecting the appropriate assumptions for calculating financial estimates.  By their nature, these judgments are subject to an inherent degree of uncertainty.  The Company periodically evaluates the judgments and estimates used in their critical accounting policies to ensure that such judgments and estimates are reasonable.  Such estimates include the allowance for doubtful accounts receivable, rebates, pensions, valuation of inventories, warranty reserves, insurance reserves, legal contingencies, assumptions used in the calculation of income taxes and the tax receivable agreement liability, projected cash flows used in the goodwill and intangible asset impairment tests, and environmental accruals and other contingencies.  These judgments are based on the Company’s historical experience, current trends and information available from other sources, and are based on management’s best estimates and judgments.  The Company adjusts such estimates and assumptions when facts and circumstances dictate.  Volatile equity markets, foreign currency, and litigation risk have combined to increase the uncertainty inherent in such estimates and assumptions.  If different conditions result from those assumptions used in the Company’s judgments, actual results could be materially different from the Company’s estimates.

Cash and Cash Equivalents

Cash and Cash Equivalents

Cash equivalents consist of short-term highly liquid investments with original maturities of three months or less and which are readily convertible into cash.

Accounts Receivable

Accounts Receivable

Accounts receivable-trade are recorded at their net realizable value.  The allowance for doubtful accounts was $3.0 million at October 1, 2016 and $3.6 million at December 31, 2015.  The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The Company estimates the allowance for doubtful accounts based on a variety of factors including the length of time receivables are past due, the financial health of its customers, unusual macroeconomic conditions and historical experience. If the financial condition of its customers deteriorates or other circumstances occur that result in an impairment of customers’ ability to make payments, the Company records additional allowances as needed. The Company writes off uncollectible trade accounts receivable against the allowance for doubtful accounts when collection efforts have been exhausted and/or any legal action taken by the Company has concluded.

Inventories

Inventories

Inventories in the accompanying condensed consolidated balance sheets are valued at the lower of cost or net realizable value and are determined primarily by the first-in, first-out (FIFO) method.  The Company records provisions, as appropriate, to write-down obsolete and excess inventory to estimated net realizable value.  The process for evaluating obsolete and excess inventory often requires the Company to make subjective judgments and estimates concerning future sales levels, quantities and prices at which such inventory will be able to be sold in the normal course of business.  Accelerating the disposal process or incorrect estimates of future sales potential may cause actual results to differ from the estimates at the time such inventory is disposed or sold. As of October 1, 2016, the Company has no inventory purchase commitments.

Inventory provisions were approximately $9.6 million at October 1, 2016, increasing during the nine months endedOctober 1, 2016 by $1.3 million compared to the December 31, 2015 provision balance of approximately $8.3 million.

Property and Equipment

Property and Equipment

Property and equipment are presented at cost.  Depreciation of property and equipment are provided on a straight-line basis over estimated useful lives, which are generally as follows: 

Buildings and improvements	10-37 years
Machinery and equipment, including leases	3-15 years
Leasehold improvements	Term of lease or useful life, whichever is shorter

(Amounts in thousands)
Accounts receivable	$	3,559
Inventories	712
Prepaid expenses and other current assets	41
Property and equipment	2,019
Intangible assets	9,300
Goodwill	7,642
Accounts payable, accrued expenses and other long-term liabilities	(2,273		)
	$	21,000

Long-lived assets

Long-lived assets

The Company reviews long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable.  The Company performs an undiscounted operating cash flow analysis to determine if impairment exists.  If an impairment is determined to exist, any related impairment loss is calculated based on the asset’s fair value and the discounted cash flows.

The Company tests for long-lived asset impairment at the following asset group levels: (i) the combined U.S. Siding, Fencing and Stone companies in the Siding, Fencing and Stone segment (“Siding”), (ii) the combined U.S. Windows companies in the Windows and Doors segment (“U.S. Windows”), (iii) the combined Simonton windows companies in the Windows and Doors segment, (iv) Gienow Canada Inc. ("Gienow Canada") (a combined Western Canadian company created by the January 2014 amalgamation of the Company's legacy Western Canadian business and the Gienow entity acquired in April 2013) in the Windows and Doors segment, and (v) Mitten in the Siding, Fencing and Stone segment. For purposes of recognition and measurement of an impairment loss, a long-lived asset or asset group should represent the lowest level for which an entity can separately identify cash flows that are largely independent of the cash flows of other assets and liabilities.  There were no indicators of impairment during the three and nine months ended October 1, 2016.

Goodwill and other intangible assets

Goodwill and other intangible assets

The Company evaluates goodwill for impairment on an annual basis and whenever events or business conditions warrant.  All other intangible assets are amortized over their estimated useful lives and are assessed for impairment as necessary.  The Company assesses goodwill for impairment at the November month end each year and also at any other date when events or changes in circumstances indicate that the carrying value of these assets may exceed their fair value.  To evaluate goodwill for impairment, the Company estimates the fair value of reporting units considering such factors as discounted cash flows and valuation multiples for comparable publicly traded companies.  A significant reduction in projected sales and earnings, which would lead to a reduction in future cash flows, could indicate potential impairment.  There were no indicators of impairment during the three and nine months ended October 1, 2016 that would trigger an interim impairment test.  The Company will continue to evaluate goodwill during future periods and future declines in the residential housing and repair and remodeling markets could result in goodwill impairments.

Debt Issuance Costs

Debt Issuance Costs

Debt issuance costs, composed of facility, agency, and certain legal fees associated with issuing new debt financing, are amortized over the contractual term of the related agreement using the effective interest method.  Net debt issuance costs totaled approximately $18.8 million and $22.2 million as of October 1, 2016 and December 31, 2015, respectively, and have been recorded within long-term debt ($16.4 million at October 1, 2016 and $19.3 million at December 31, 2015) and other non-current assets ($2.5 million at October 1, 2016 and $2.9 million at December 31, 2015) in the accompanying condensed consolidated balance sheets. The debt issuance costs included in other long term assets relate to the Senior Secured Asset Based Revolving Credit Facility due 2020 ("ABL Facility"). Amortization of debt issuance costs for the three months ended October 1, 2016 and October 3, 2015 was approximately $0.8 million and $0.8 million, respectively. Amortization of debt issuance costs for the nine months endedOctober 1, 2016 and October 3, 2015 was approximately $2.5 million and $2.3 million, respectively. Amortization of debt issuance costs is recorded in interest expense in the accompanying condensed consolidated statements of operations and comprehensive income.

Income Taxes

Income Taxes

The Company utilizes the asset and liability method of accounting for income taxes which requires that deferred tax assets and liabilities be recorded to reflect the future tax consequences of temporary differences between the book and tax basis of various assets and liabilities.  Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.  The effect of changes in tax rates on deferred tax assets and liabilities is recognized as income or expense in the period in which the rate change occurs.  A valuation allowance is established to offset any deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

Estimates are required with respect to, among other things, the appropriate state income tax rates used in the various states that the Company and its subsidiaries are required to file, the potential utilization of operating and capital loss carry-forwards for both federal and state income tax purposes and valuation allowances required, if any, for deferred tax assets that may not be realized in the future.  The Company establishes reserves when, despite our belief that our tax return positions are fully supportable, certain positions could be challenged, and the positions may not be fully sustained.  The Company, along with its U.S. subsidiaries, file a consolidated federal income tax return, separate state income tax returns, combined state returns, and unitary state returns. Gienow Canada and Mitten both file separate Canadian federal income tax returns and separate provincial returns.

Tax receivable agreement ("TRA") liability

The TRA liability generally provides for the payment by the Company to the Tax Receivable Entity of 85% of the amount of cash savings, if any, in the U.S. federal, state and local income tax that the Company actually realizes in periods ending after the Company's initial public offering as a result of (i) net operating loss carryovers ("NOLs") from periods ending before January 1, 2013, (ii) deductible expenses attributable to the initial public offering and (iii) deductions related to imputed interest. Since the inception of the TRA liability with the Company’s 2013 initial public offering, the Company has been in a full valuation allowance for federal purposes and had partial valuation allowances on certain state and Canadian jurisdictions. As a result of the Company’s tax valuation allowance position for federal and state purposes, the Company calculated the TRA liability considering (i) current year taxable income only (due to the uncertainty of future taxable income associated with the Company’s cumulative loss position) and (ii) future income due to the expected reversals of deferred tax liabilities. During the three and nine months ended October 1, 2016, the Company released its valuation allowance on its federal deferred tax assets and certain state deferred tax assets for approximately $50.1 million due to positive factors outweighing negative evidence thereby allowing the Company to achieve the “more likely than not” realization threshold. This release thereby eliminated any uncertainty as to future taxable income. Consequently, for purposes of calculating the TRA liability, the Company during the three months ended October 1, 2016 utilized future forecasts of taxable income beyond the 2016 tax year to determine the TRA liability. The Company’s future taxable income estimate was used to determine the cumulative NOLs that are expected to be utilized and the TRA liability was accordingly adjusted using the 85% TRA rate as the Company retains the benefit of 15% of the tax savings.

Environmental

Environmental

The Company accrues for losses associated with environmental remediation obligations when such losses are probable and reasonably estimable. Environmental remediation obligation accruals are adjusted as further information develops or circumstances change.  Costs of future expenditures for environmental remediation obligations are not discounted to their present value.  Recoveries of environmental remediation costs from other parties are recorded as assets when their receipt is deemed probable.

Commitments and Contingencies, Policy

Commitments and Contingencies

The Company accrues for all direct costs associated with the estimated resolution of contingencies at the earliest date at which it is deemed probable that a liability has been incurred and the amount of such liability can be reasonably estimated.  Costs accrued have been estimated based upon an analysis of potential results, assuming a combination of litigation and settlement strategies and outcomes. Insurance recoveries are recorded as assets when their receipt is deemed probable.

Foreign Currency

Foreign Currency

Gienow Canada and Mitten, the Company’s Canadian subsidiaries, utilize the Canadian dollar as their functional currency.  For reporting purposes, the Company translates the assets and liabilities of its foreign entities at the exchange rates in effect at period-end.  Net sales and expenses are translated using average exchange rates in effect during the period.  Gains and losses from foreign currency translation are credited or charged to accumulated other comprehensive income or loss in the accompanying condensed consolidated balance sheets.

The Company recorded a loss from foreign currency transactions of approximately $0.1 million and $1.1 million for the three months ended October 1, 2016 and October 3, 2015, respectively. The Company recorded a gain from foreign currency transactions of approximately $0.7 million for the nine months ended October 1, 2016 and a loss of approximately $2.1 million for the nine months ended October 3, 2015. During the nine months ended October 1, 2016, accumulated other comprehensive income (loss) included a currency translation gain of approximately $4.1 million and a loss of approximately $11.3 million for the nine months ended

Derivatives, Policy [Policy Text Block]

Derivative Financial Instruments

As of October 1, 2016, the Company had entered into foreign currency forward contract agreements to hedge approximately $78.1 million of its 2016 and 2017 non-functional currency inventory purchases to protect the Company from variability in cash flows attributable to changes in the U.S. dollar relative to the Canadian dollar.

The Company has designated these forward contracts as cash flow hedges. As a cash flow hedge, unrealized gains are recognized as assets while unrealized losses are recognized as liabilities. These forward contract agreements are highly correlated to the changes in foreign currency rates to which the Company is exposed. Unrealized gains and losses on these agreements are designated as effective or ineffective. The effective portion of such gains or losses is recorded as a component of accumulated other comprehensive income or loss, while the ineffective portion of such gains or losses is recorded as a component of cost of goods sold. Future realized gains and losses in connection with each inventory purchase will be reclassified from accumulated other comprehensive income or loss to cost of goods sold.

The changes in fair values of derivatives that have been designated and qualify as cash flow hedges are recorded in accumulated other comprehensive income or loss and are reclassified into cost of goods sold in the same period the hedged item affects earnings. Due to the high degree of effectiveness between the hedging instruments and the underlying exposures being hedged, fluctuations in the value of the derivative instrument are generally offset by changes in the fair value or cash flows of the underlying exposures being hedged. The changes in the fair value of derivatives that do not qualify as effective are immediately recognized in earnings.

The gains and losses on derivative contracts that are reclassified from accumulated other comprehensive income or loss to current period earnings are included in the line item in which the hedged item is recorded in the same period the forecasted transaction affects earnings. As of October 1, 2016, approximately $0.3 million of the deferred net asset on derivative instruments included in accumulated other comprehensive loss is expected to be reclassified to cost of goods sold during the next twelve months. This expectation is based on the expected timing of the occurrence of the hedged forecasted transactions. During the three and nine months ended October 1, 2016, the Company recognized $0.2 million and $0.5 million, respectively, within earnings as an increase to cost of goods sold in the condensed consolidated statement of operations and comprehensive income. During the three and nine months ended October 3, 2015, the Company recognized $1.8 million and $3.9 million, respectively, within earnings as a reduction of cost of goods sold in the condensed consolidated statement of operations and comprehensive income.

The fair value of the foreign currency forward contract agreements are estimated using industry standard valuation models using market-based observable inputs, including spot rates, forward points, interest rates and volatility inputs (Level 2).

Fair Value Measurement

Fair Value Measurement

The accounting standard for fair value discusses valuation techniques, such as the market approach (comparable market prices), the income approach (present value of future income or cash flows), and the cost approach (cost to replace the service capacity of an asset or replacement cost). The standard utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels:

• Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities.

• Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.

• Level 3: Inputs that reflect the reporting entity’s own assumptions.

The hierarchy requires the use of observable market data, when available, and to minimize the use of unobservable inputs when determining fair value.  The fair value of the long-term debt instruments was determined by utilizing available market information.  The carrying value of the Company’s other assets and liabilities approximates their fair value.

Earnings (loss) per common share

Earnings (Loss) Per Common Share

Basic earnings (loss) per share ("EPS") is computed based upon weighted-average shares outstanding during the period. Dilutive earnings per share is computed consistently with the basic computation while giving effect to all dilutive potential common shares and common share equivalents that were outstanding during the period. Ply Gem Holdings uses the treasury stock method to reflect the potential dilutive effect of unvested stock awards and unexercised options.

The computation of the dilutive effect of other potential common shares included options and unvested restricted stock representing approximately 0.2 million and 0.1 million shares of common stock for the three and nine months endedOctober 1, 2016, respectively. The computation of the dilutive effect of other potential common shares included options and unvested restricted stock representing approximately 0.1 million and 0.1 million shares of common stock for the three and nine months ended October 3, 2015, respectively.

New accounting pronouncements

New Accounting Pronouncements

In August 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 addresses how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230, Statement of Cash Flow, and Other Topics. ASU 2016-15 is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2017. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements.

In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting. The amendments in this updated guidance include changes to simplify the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This guidance is effective for fiscal years beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is permitted. The Company is in the process of evaluating the potential impacts of this new guidance on its consolidated financial statements.

In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606), Principal versus Agent Considerations (Reporting Revenue Gross versus Net). This update provides guidance on recording revenue on a gross basis versus a net basis based on the determination of whether an entity is a principal or an agent when another party is involved in providing goods or services to a customer. The amendments in this update affect the guidance in ASU No. 2014-09 and are effective in the same timeframe as ASU No. 2014-09 as discussed below.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The core principal of the guidance is that an entity should recognize assets and liabilities arising from a lease for both financing and operating leases, along with additional qualitative and quantitative disclosures. The standard will be effective for fiscal years beginning after December 15, 2018, including interim periods within such fiscal years. Early adoption is permitted. The guidance is to be applied using a modified retrospective transition method with the option to elect a package of practical expedients. The Company is currently evaluating the impact of the adoption of this accounting standard update on its internal processes, operating results and financial reporting. The impact is currently not known or reasonably estimable.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which completes the joint effort by the FASB and the International Accounting Standards Board to clarify the principles for recognizing revenue and improve financial reporting by creating common revenue recognition guidance for U.S. generally accepted accounting principles ("GAAP") and International Financial Reporting Standards ("IFRS"). ASU 2014-09 provides enhancements to the quality and consistency of how revenue is reported while also improving comparability in the financial statements of companies reporting using IFRS and GAAP. The core principle of this update is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB finalized a one-year deferral of the effective date of the new revenue recognition standard. The new standard will become effective for Ply Gem beginning with the first quarter of 2018 and can be adopted either retrospectively to each prior reporting period presented or as a cumulative effect adjustment as of the date of adoption. The method of adoption has not been determined yet by the Company. The Company is currently reviewing the revised guidance and assessing the potential impact on the consolidated financial statements.
