Basis of Presentation	'
	NOTE 1. BASIS OF PRESENTATION
	The accompanying unaudited condensed consolidated financial statements include the accounts of PGT, Inc. and its wholly-owned subsidiary, PGT Industries, Inc., and its wholly-owned subsidiary CGI Window and Holdings, Inc. for the period from September 23, 2014, through September 27, 2014, and as of September 27, 2014 (“CGI”) (collectively the “Company”), after elimination of intercompany accounts and transactions. These statements have been prepared in accordance with the instructions to Form 10-Q and do not include all of the information and footnotes required by United States Generally Accepted Accounting Principles (“GAAP”) for complete financial statements. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the interim period are not necessarily indicative of the results that may be expected for the remainder of the current year or for any future periods. Each of our Company’s fiscal quarters ended September 27, 2014, and September 28, 2013, consisted of 13 weeks.
	The Condensed Consolidated Balance Sheet as of December 28, 2013, is derived from the audited consolidated financial statements, but does not include all disclosures required by GAAP. The Condensed Consolidated Balance Sheets as of December 28, 2013, and the unaudited condensed consolidated financial statements as of and for the period ended September 27, 2014, should be read in conjunction with the more detailed audited consolidated financial statements for the year ended December 28, 2013, included in the Company’s most recent Form 10-K annual report. Accounting policies used in the preparation of these unaudited condensed consolidated financial statements are consistent with the accounting policies described in the Notes to Consolidated Financial Statements included in the Company’s Form 10-K.
	Recently Issued Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2013-11, “Income Taxes: Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward Exists,” which requires tax benefits to be presented in the financial statement as a reduction to deferred tax asset for a net operating loss carryforward or a tax credit carryforward. We adopted this standard in the first quarter of 2014, and it did not impact the condensed consolidated financial statements.

Warranty

Guarantees [Abstract]	'
Warranty	'
	NOTE 2. WARRANTY
	Most of our manufactured products are sold with warranties. Warranty periods, which vary by product components, generally range from 1 to 10 years; however, the warranty period for a limited number of specifically identified components in certain applications is a lifetime. The majority of the products sold have warranties on components which range from 1 to 3 years. The reserve for warranties is based on management’s assessment of the cost per service call and the number of service calls expected to be incurred to satisfy warranty obligations on the current net sales.
	During the three months and nine months ended September 27, 2014, we recorded warranty expense at a rate of 2.00% and 1.74% of sales, respectively. These rates are higher than the 1.32% of sales accrued in the first nine months 2013, due to an increase in the number of service claims. This increase in claims is a result of quality related issues driven by a large number of new hires. We assess the adequacy of our warranty accrual on a quarterly basis and adjust the previous amounts recorded, if necessary, to reflect a change in estimate of the future costs of claims yet to be serviced.
	The following table summarizes: current period charges, adjustments to previous estimates, if necessary, as well as settlements, which represent actual costs incurred during the period for the three and nine months ended September 27, 2014, and September 28, 2013. The reserve is determined through specific identification and assessing Company history. Expected future obligations are discounted to a current value using a risk-free rate for obligations with similar maturities.
	The following provides information with respect to our warranty accrual:
	Accrued Warranty	Beginning		Charged to		Adjustments			Settlements			End of
		of Period		Expense								Period
		(in thousands)
	Three months ended September 27, 2014	$	2,736	$	1,535	$	271		$	(1,337	)	$	3,205

	NOTE 4. STOCK COMPENSATION EXPENSE
	On March 28, 2014, the Board of Directors adopted, and on May 7, 2014, our stockholders approved, the PGT, Inc. 2014 Omnibus Equity Incentive Plan. The Board of Directors determined that grants of restricted shares and other share-based awards to our officers, employees, directors, independent contractors and consultants are an important part of our long-term incentive compensation program, which we use in order to strengthen the commitment of such individuals to the Company, motivate them to faithfully and diligently perform their responsibilities, and attract and retain competent and dedicated individuals, whose efforts will result in the long-term growth and profitability of the Company.
	2014 Omnibus Equity Incentive Plan
	The 2014 Omnibus Equity Incentive Plan, among other things:
		•	provides 1,500,000 common shares available for grants of equity awards,
		•	sets forth the types of awards eligible under the plan, including issuances of options, share appreciation rights, restricted shares, restricted share units, share bonuses, other share-based awards and cash awards,
		•	identifies those eligible to receive the equity awards, including company officers, employees, directors, and certain independent contractors and consultants, and
		•	confirms that the governance and administration of such equity plan is the responsibility of the Board of Directors, or Compensation Committee at the direction of the Board.
	Exercises
	In the third quarter of 2014, there were 317,708 options exercised at a weighted average exercise price of $2.22 per share. For the nine months ended September 27, 2014, there were 815,776 options exercised at a weighted average exercise price of $1.84 per share.
	Issuance
	For the nine months ended September 27, 2014, we granted 20,000 options and 178,777 restricted stock awards to certain directors, executive and non-executive employees of the Company. The options vest over a five-year period from March 4, 2014, and have an exercise price of $11.81 per share equal to the NASDAQ market price of the underlying common stock on the close of business on the last trading day before the options were granted. The restricted stock awards granted in the first quarter were issued as two separate grants, the first being both performance and service based awards with a weighted average fair value on date of grant of $11.81 per share equal to the NASDAQ market price of the common stock on the close of business on the day the awards were granted, and vest over a three-year period. The second awards were service based only, with a weighted average fair value on date of grant of $11.81 per share based on the NASDAQ market price of the common stock on the close of business on the day the awards were granted, and vest over various periods up to three years.
	We record stock compensation expense over an award’s vesting period based on the award’s fair value at the date of grant. We recorded compensation expense for stock based awards of $0.3 million for the third quarter of 2014 and $0.2 million for the third quarter of 2013. We recorded compensation expense for stock based awards of $0.9 million for the first nine months of 2014 and $0.8 million for the first nine months of 2013. As of September 27, 2014, and September 28, 2013, there was $1.4 million and $0.7 million, respectively, of total unrecognized compensation cost related to non-vested stock option agreements and restricted share awards. These costs are expected to be recognized in earnings on a straight-line basis over the weighted average remaining vesting period of 1.5 years.

Net Income Per Common Share	'
	NOTE 5. NET INCOME PER COMMON SHARE
	Basic EPS is computed by dividing net income available to common shareholders, by the weighted-average number of common shares outstanding during the period. Diluted EPS reflects the dilutive effect of potential common shares from securities such as stock options.
	Our weighted average shares outstanding for the three months ended September 27, 2014, and September 28, 2013, excludes underlying options and restricted stock awards of 92,463 and 22,510 respectively, because their effects were anti-dilutive. Our weighted average shares outstanding for the nine months ended September 27, 2014, and September 28, 2013, excludes underlying options and restricted stock awards of 70,195 and 15,007, respectively, because their effects were anti-dilutive.

Acquisition	'
	NOTE 6. ACQUISITION
	On September 22, 2014 (the Closing Date), we completed the acquisition of CGI which became a wholly-owned subsidiary of PGT, Inc. The transaction, valued at approximately $110.4 million, is consistent with our plan to grow strategically while contributing to earnings growth through targeted acquisitions of complementary specialty products. This acquisition was financed with a new credit facility totaling $235 million, of which $200.0 million is term debt and $35.0 million is undrawn revolver. Proceeds of the term loan were used to consummate the acquisition, repay existing indebtedness, and pay fees and expenses. The estimated fair value of assets acquired and liabilities assumed as of the Closing Date are as follows:
		Fair
		Values
		(in thousands)
	Accounts receivable, net	$	4,156
	Inventories		3,229
	Prepaid expenses		303
	Property, plant and equipment, net		1,709

	Other liabilities		(351	)
	Net Assets Acquired		43,780
	Purchase Price		110,438
	Goodwill	$	66,658
	The purchase price paid was preliminarily allocated to the net assets acquired based on their fair value on September 22, 2014, in accordance with ASC 805 “Business Combinations”. We are in the process of finalizing the valuation of assets acquired and liabilities assumed, including the valuation of intangible assets. The fair value of working capital related items, such as accounts receivable, inventories, prepaids, and accounts payable and accrued liabilities, were assumed to equal book value at the date of acquisition. The intangible assets (see note 7) were estimated using income and royalty relief approaches based on projections provided by management, which we consider to be Level 3 inputs. Once our final valuation of identified intangibles is complete, we will adjust our preliminary estimates accordingly. Acquisition costs totaling $1.5 million are included in selling, general, and administrative expenses on the condensed consolidated statements of comprehensive income for the three and nine months ended September 27, 2014, and relate to legal expenses, diligence, and accounting services.
	Net sales and net income included in the consolidated condensed statement of comprehensive income for the three and nine months ended September 27, 2014, from CGI for the period from September 23, 2014, to September 27, 2014, are $552 thousand and $8 thousand, respectively.
	Preliminary valuation of identified intangible assets
	We are in the process of finalizing the valuation of the identifiable intangible assets acquired in the CGI acquisition. The preliminary values and our estimate of their respective useful lives are as follows:
					Original
		Asset			Useful Life
		Amount			(in years)
		(in thousands)
	Identifiable Intangible Asset Description:
	Trade names	$	19,000		indefinite
	Customer relationships		24,000		8
	Developed technology		1,700		5
	Non-compete agreements		600		2
	Total identified intangible assets	$	45,300
	Once our final valuation of the identified intangible assets is complete, we will adjust our preliminary estimates accordingly. We use the straight-line method of amortization for the finite lived intangible assets, and recorded an immaterial amount of amortization expense within selling, general, and administrative expenses in the condensed consolidated statements of comprehensive income for the three and nine months ended September 27, 2014.
	Preliminary estimate of goodwill
	The remaining consideration, after adjusting for the preliminary estimate of the identified intangible assets, and the net assets and liabilities recorded at fair value, was preliminarily determined to be $66.7 million, of which $9.3 million is expected to be deductible for tax purposes. Goodwill represents the increased value of the combined entity through additional sales channel opportunities as well as operational efficiencies. To the extent that our preliminary value of identified intangible assets changes, there will be an equal and offsetting change to the recorded goodwill.
	Selected Unaudited Pro Forma financial information
	The following unaudited pro forma financial information assumes the acquisition had occurred at the beginning of the earliest period presented. Pro forma results have been prepared by adjusting our historical results to include the results of CGI adjusted for the following: amortization expense related to the estimated intangible assets arising from the acquisition and interest expense to reflect the new Credit Agreement entered into in connection with the acquisition.
	The unaudited pro forma results do not necessarily reflect the results of operations that would have resulted had the acquisition been completed at the beginning of the applicable periods presented, nor does it indicate the results of operations in future periods. The unaudited pro forma results do not include the impact of synergies, nor any potential impacts on current or future market conditions which could alter the following unaudited pro forma results.

	Indefinite Lived Intangible Asset
	As a result of the acquisition of CGI, we added a trade name with a fair value of $19.0 million. The impairment evaluation of the carrying amount of intangible assets with indefinite lives is conducted annually, or more frequently if events or changes in circumstances indicate that an asset might be impaired. The evaluation is performed by comparing the carrying amounts of these assets to their estimated fair values. If the estimated fair value is less than the carrying amount of the intangible assets, an impairment charge is recorded to reduce the asset to its estimated fair value. The estimated fair value is determined using the relief from royalty method that is based upon the discounted projected cost savings (value) attributable to ownership of our trade names.
	In estimating fair value, the method we use requires us to make assumptions, the most material of which are net sales projections attributable to products sold with these trade names, the anticipated royalty rate we would pay if the trade names were not owned (as a percent of net sales), and a weighted average discount rate. These assumptions are subject to change based on changes in the markets in which these products are sold, which impact our projections of future net sales and the assumed royalty rate. Factors affecting the weighted average discount rate include assumed debt to equity ratios, risk-free interest rates, and equity returns, each for market participants in our industry.
	Our annual test of trade names that existed prior to our acquisition of CGI, performed as of December 28, 2013, utilized a weighted average royalty rate of 4.0% and a discount rate of 16.1%. As of December 28, 2013, the estimated fair value of the trade names exceeded book value by approximately 79%, or $30.3 million. We believe our projected sales are reasonable based on available information regarding our industry and the core markets that we serve. We also believe the royalty rate is appropriate and could improve over time based on market trends and information, including that which is previously set forth. The discount rate was based on current financial market trends and will remain dependent on such trends in the future.
	No impairment test was conducted during the nine months ended September 27, 2014, because no impairment indicators were identified.
	Amortizable Intangible Assets
	We perform an impairment test on our amortizable intangible assets any time that impairment indicators exist. Such assets include customer relationships, intellectual property, and non-compete agreements and were acquired through the acquisition of CGI on September 27, 2014. Going forward, we will monitor and evaluate potential impairment indicators which could result in impairment.

Long-Term Debt	'
	NOTE 8. LONG-TERM DEBT
	On September 22, 2014, we entered into a Credit Agreement (the “Credit Agreement”), among us, the lending institutions identified in the Credit Agreement, and Deutsche Bank AG New York Branch, as Administrative Agent and Collateral Agent. The Credit Agreement establishes new senior secured credit facilities in an aggregate amount of $235.0 million, consisting of a $200.0 million Term B term loan facility maturing in seven years that will amortize on a basis of 1% annually during the seven-year term, and a $35.0 million revolving credit facility maturing in five years that includes a swing line facility and a letter of credit facility. Our obligations under the Credit Agreement are secured by substantially all of our assets as well as our direct and indirect subsidiaries’ assets. As of September 27, 2014, there were $0.6 million of letters of credit outstanding and $34.4 million available on the revolver.
	Interest on all loans under the Credit Agreement is payable either quarterly or at the expiration of any LIBOR interest period applicable thereto. Borrowings under the term loans and the revolving credit facility accrue interest at a rate equal to, at our option, LIBOR (with a floor of 100 basis points in respect of the term loan), or a base rate (with a floor of 200 basis points in respect of the term loan) plus an applicable margin. The applicable margin is 425 basis points in the case of LIBOR and 325 basis points in the case of the base rate. We will pay quarterly fees on the unused portion of the revolving credit facility equal to 50 basis points per annum as well as a quarterly letter of credit fee at 425 basis points per annum on the face amount of any outstanding letters of credit.
	The Credit Agreement contains a springing financial covenant, if we draw in excess of twenty percent (20%) of the revolving facility, which requires us to maintain a maximum total net leverage ratio (based on the ratio of total debt for borrowed money to trailing EBITDA, each as defined in the Credit Agreement), and will be tested quarterly based on the last four fiscal quarters and is set at levels as described in the Credit Agreement. As of September 27, 2014, no such test is required as we have not exceeded 20% of our revolving capacity.
	The Credit Agreement also contains a number of affirmative and restrictive covenants, including limitations on the incurrence of additional debt, liens on property, acquisitions and investments, loans and guarantees, mergers, consolidations, liquidations and dissolutions, asset sales, dividends and other payments in respect of our capital stock, prepayments of certain debt and transactions with affiliates. The Credit Agreement also contains customary events of default. Upon the occurrence of an event of default, the amounts outstanding under the Credit Agreement may be accelerated and may become immediately due and payable.
	In connection with entering into the Credit Agreement, on September 22, 2014, we terminated our prior credit agreement, dated as of May 28, 2013, among PGT Industries, Inc., as the borrower, the Company, as guarantor, the lenders from time to time party thereto and SunTrust Bank, as administrative agent and collateral agent (the “2013 Credit Agreement”). Proceeds from the term loan facility under the Credit Agreement were used to repay amounts outstanding under the 2013 Credit Agreement and the acquisition of CGI, and certain fees and expenses.
	When entering into the 2013 Credit Agreement, we terminated our prior credit agreement, dated as of June 23, 2011, among PGT Industries, Inc., as the borrower, the Company, as guarantor, the lenders from time to time party thereto and General Electric Capital Corporation, as administrative agent and collateral agent (the “2011 Credit Agreement”). Proceeds from the term loan facility under the 2013 Credit Agreement were used to repay amounts outstanding under the 2011 Credit Agreement, repurchase shares of our common stock having an aggregate value of approximately $50 million, and pay certain fees and expenses.
	On September 16, 2013, we entered into two interest rate caps and an interest rate swap to hedge a portion of the 2013 Credit Agreement against volatility in future interest rates. As of September 27, 2014, we have one cap and the swap outstanding. As a result of the termination of the 2013 Credit Agreement, the underlying transaction is no longer probable of occurring and both instruments have been de-designated and will be marked to market in this and future reporting periods (See Note 12).
	The face value of the debt as of September 27, 2014, was $200.0 million. Related debt issuance costs and the debt discount are being amortized to interest expense, net on the Condensed Consolidated Statements of Comprehensive Income over the term of the debt.
	As a result of the refinancing, we recorded $2.8 million in debt extinguishment costs related to the write-off of deferred financing costs on the previous facility, as well as unamortized debt discount, on the Condensed Consolidated Statements of Comprehensive Income for the three and nine months ended September 27, 2014.

	NOTE 11. INCOME TAXES
	We recognized income taxes at a rate of 42.1%, which is higher than the statutory rate of 38.8% for the three months ended September 27, 2014. The rate is higher due mainly to increasing our estimated annual rate to 38.5% from our previously estimated rate of 37.7% as a result of the reduction in our expected Section 199 manufacturing deduction. The reduction is a result of increased taxable stock compensation and the estimated use of acquired net operating losses in 2014.
	We recognized income taxes at a rate of 38.5%, which is slightly lower than the statutory rate of 38.8% for the nine months ended September 27, 2014. The rate, however, is higher than the previously estimated annual rate of 37.7% as a result of the reduction in our expected Section 199 manufacturing deduction. The reduction is a result of increased taxable stock compensation and the estimated use of acquired net operating losses in 2014.
	We recorded an income tax benefit of $3.9 million for the nine months ended September 28, 2013. The income tax benefit in the prior year was due to a reversal of a portion of our deferred tax asset valuation allowance in the second quarter. As of the year ended 2013 and the nine months ended September 27, 2014, we have no valuation allowance on our deferred tax assets.
	In connection with the acquisition of CGI, we recorded a net deferred tax liability of $6.5 million, consisting of $13.6 million in deferred tax liabilities relating to the non-deductible intangible assets acquired, $0.2 million in other net deferred tax liabilities, offset by deferred tax assets relating to $7.3 million of tax affected net operating losses.

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
Derivatives	'
	NOTE 12. DERIVATIVES
	We enter into aluminum forward contracts to hedge the fluctuations in the purchase price of aluminum extrusion we use in production. Our contracts are designated as cash flow hedges since they are highly effective in offsetting changes in the cash flows attributable to forecasted purchases of aluminum.
	In addition, we entered into LIBOR rate hedges on September 16, 2013, to offset the changes in cash flows of the debt interest rate payments that are attributable to the fluctuations of LIBOR rates.
	We net cash collateral from payments of margin calls on deposit with our brokers against the liability position of open contracts for the purchase of hedge instruments on a first-in, first-out basis. For statement of cash flows presentation, we present net cash receipts from and payments to the margin account as investing activities.
	Derivative Financial Instruments – Aluminum Contracts
	Guidance under the Financial Instruments topic of the Codification requires us to record our hedge contracts at fair value and consider both our credit risk for contracts in a liability position, as well as our counter-party’s credit risk for contracts in an asset position, when determining fair value. We assess our counter-party’s risk of non-performance when measuring the fair value of financial instruments in an asset position, by evaluating their financial position, including cash on hand, as well as their credit ratings. We assess our risk of non-performance when measuring the fair value of our financial instruments in a liability position, by evaluating our credit ratings, our current liquidity, including cash on hand, and availability under our revolving credit facility as compared to the maturities of the financial liabilities. In addition, we entered into a master netting arrangement (MNA) with our commodities broker that provides for, among other things, the close-out netting of exchange-traded transactions in the event of the insolvency of either party to the MNA.
	We maintain a $2.0 million line of credit with our commodities broker to cover the liability position of open contracts for the purchase of aluminum in the event that the price of aluminum falls. Should the price of aluminum fall to a level which causes our liability for open aluminum contracts to exceed $2.0 million, we are required to fund daily margin calls to cover the excess.
	At September 27, 2014, the fair value of our aluminum forward contracts was in a net liability position of approximately $30 thousand. We had 32 outstanding forward contracts for the purchase of 10.4 million pounds of aluminum, approximately 34% of our anticipated needs through December 2015, at an average price of $0.90 per pound with maturity dates of between less than one month and fifteen months. We assessed the risk of non-performance of the Company to these contracts and recorded a de minimis adjustment to fair value as of September 27, 2014.
	Although it is our intent to have our aluminum hedges qualify as highly effective for reporting purposes, for the three months ended September 27, 2014, all 32 outstanding contracts did not qualify as effective. Effectiveness of aluminum forward contracts is determined by comparing the change in the fair value of the forward contract to the change in the expected cash to be paid for the hedged item. The effective portion of the gain or loss on our aluminum forward contracts is reported as a component of accumulated other comprehensive loss and is reclassified into earnings in the same line item in the income statement as the hedged item in the same period or periods during which the transaction affects earnings. When a cashflow hedge becomes ineffective, and if the forecasted hedged transaction is still probable of occurrence, amounts previously recorded in accumulated other comprehensive loss remain in accumulated other comprehensive loss and are recognized in earnings in the period in which the hedged transaction affects earnings. The change in value of the aluminum forward contracts occurring after ineffectiveness is recognized in other expense, net on the Condensed Consolidated Statements of Comprehensive Income. The amount of losses recognized in the “accumulated other comprehensive loss” line item in the accompanying Condensed Consolidated Balance Sheets (unaudited) as of September 27, 2014, that will be reclassified to earnings within the next three months, will be immaterial.
	As of December 28, 2013, the fair value of our aluminum forward contracts was in a net asset position of approximately $479 thousand. We had 33 outstanding forward contracts for the purchase of 9.5 million pounds of aluminum at an average price of $0.89 per pound with maturity dates of between less than one month and 18 months through June 2015. We assessed the risk of non-performance of the counterparty on these contracts and recorded a de minimis adjustment to fair value as of December 28, 2013.
	As of December 28, 2013, our aluminum hedges did not qualify as effective for reporting purposes. Amounts previously recorded in accumulated other comprehensive loss, remain in accumulated other comprehensive loss and are recognized in earnings in the period in which the hedged transaction affects earnings. The change in value of the aluminum forward contracts occurring after ineffectiveness is recognized in other expense, net on the Condensed Consolidated Statements of Comprehensive Income.
	Derivative Financial Instruments – Interest Rate Contract
	On September 16, 2013, we entered into two interest rate caps and an interest rate swap to hedge a portion of the 2013 Credit Agreement against volatility in future interest rates. The first interest rate cap expired during the three months ended September 27, 2014. The second interest rate cap is a two-year agreement with a notional amount of $20.0 million; it was designated as a cash flow hedge that protects the variable rate debt from an increase in the floating, one-month LIBOR rate of greater than 0.50%.
	The interest rate swap is a forward-starting, three-year, six-month agreement with a notional amount of $40.0 million that effectively converts a portion of the floating rate debt to a fixed rate of 2.15%. It started September 28, 2014, and has a termination date of May 18, 2018.
	As of September 27, 2014, we have one cap and the swap outstanding. As a result of the termination of the 2013 Credit Agreement, both instruments have been de-designated and will be marked to market in this and future reporting periods.

Fair Value Disclosures [Abstract]	'
Fair Value	'
	NOTE 13. FAIR VALUE
	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A three-tier fair value hierarchy is used to prioritize the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted market prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The three levels of the fair value hierarchy are as follows:
	Level 1 Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.
	Level 2 Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly.
	Level 3 Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.
	The accounting guidance concerning fair value allows us to elect to measure financial instruments at fair value and report the changes in fair value through the Condensed Consolidated Statements of Income and Comprehensive Income. This election can only be made at certain specified dates and is irrevocable once made. We do not have a policy regarding specific assets or liabilities to elect to measure at fair value, but rather make the election on an instrument-by-instrument basis as they are acquired or incurred.
	Items Measured at Fair Value on a Recurring Basis
	The following assets and liabilities are measured in the Condensed Consolidated Balance Sheets at fair value on a recurring basis and are categorized in the table below based upon the lowest level of significant input to the valuation:

	The following is a description of the methods and assumptions used to estimate the fair values of our assets and liabilities measured at fair value on a recurring basis, as well as the basis for classifying these assets and liabilities as Level 2.
	Aluminum forward contracts identical to those held by us trade on the London Metal Exchange (“LME”). The LME provides a transparent forum and is the world’s largest center for the trading of futures contracts for non-ferrous metals. The prices are used by the metals industry worldwide as the basis for contracts for the movement of physical material throughout the production cycle. Based on this high degree of volume and liquidity in the LME, we believe the valuation price at any measurement date for contracts with identical terms as to prompt date, trade date and trade price as those we hold at any time represents a contract’s exit price to be used for purposes of determining fair value.
	Interest rate cap and swap contracts identical to that held by us are sold by financial institutions. The valuation price at any measurement date for a contract with identical terms, exercise price, expiration date, settlement date, and notional quantities, as the one we hold, is used for determining the fair value.

	The following table presents the carrying values and estimated fair values of financial assets and liabilities that are required to be recorded or disclosed at fair value at September 27, 2014, and December 28, 2013, respectively:
