Summary of Significant Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

2.	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Accounting

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and include the accounts of the Company and its wholly-owned subsidiary, Trex Wood-Polymer Espana, S.L. (“TWPE”). Intercompany accounts and transactions have been eliminated in consolidation.

TWPE was formed to hold the Company’s 35% equity interest in Denplax, S.A. (“Denplax”), a joint venture with a Spanish Company responsible for public environmental programs in southern Spain and with an Italian equipment manufacturer. The joint venture was formed to recycle polyethylene at a facility in El Ejido, Spain. The Company’s investment in Denplax is accounted for using the equity method. During 2010, the Company determined that its investment in Denplax and a related note receivable were no longer recoverable and recorded a $2.4 million charge to earnings to fully reserve the equity investment and note. Both the equity investment and note remain fully reserved as of December 31, 2012.

Iron Deck Acquisition

On May 2, 2011, the Company completed the acquisition of substantially all of the assets of Iron Deck Corporation, a manufacturer of steel deck framing systems located in Denver, Colorado, for approximately $2 million in cash plus the assumption of certain liabilities. As a result of the acquisition, the Company recorded an increase of $3.7 million to Goodwill. No other material tangible or intangible assets were identified. The provisions of the purchase agreement allow for future payments contingent upon certain future sales targets. The contingent payments were estimated as purchase consideration at the acquisition date and may be revised if actual sales differ from projected sales. As a result of decreased near-term sales projections of steel deck framing systems, the Company reduced its provision for future contingent payments and recorded a $1.4 million benefit to selling, general and administrative expenses in the year ended December 31, 2012.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and the accompanying notes. Actual results could differ from those estimates.

Cash and Cash Equivalents

Cash equivalents consist of highly liquid investments purchased with original maturities of three months or less.

Concentrations and Credit Risk

The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, and trade accounts receivable. The Company from time to time may have bank deposits in excess of insurance limits of the Federal Deposit Insurance Corporation. As of December 31, 2012, substantially all deposits are maintained in one financial institution. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk related to its cash and cash equivalents.

The Company routinely assesses the financial strength of its customers and believes that its trade receivables credit risk exposure is limited. Trade receivables are carried at the original invoice amount less an estimate made for payment discounts and doubtful accounts. A valuation allowance is provided for known and anticipated credit losses and disputed amounts, as determined by management in the course of regularly evaluating individual customer receivables. This evaluation takes into consideration a customer’s financial condition and credit history, as well as current economic conditions.

In the years ended December 31, 2012, 2011 and 2010, sales to certain customers accounted for 10% or more of the Company’s total net sales. For the year ended December 31, 2012, two customers of the Company represented approximately 26% and 10% of the Company’s net sales. For the year ended December 31, 2011, one customer of the Company represented approximately 24% of the Company’s net sales. For the year ended December 31, 2010, one customer of the Company represented approximately 28% of the Company’s net sales. As of December 31, 2012, two customers represented 31% and 20%, respectively, of the Company’s accounts receivable balance.

Approximately 40%, 33%, and 41% of the Company’s raw materials purchases for the years ended December 31, 2012, 2011 and 2010, respectively, were purchased from its four largest suppliers.

Inventories

Inventories are stated at the lower of cost (last-in, first-out, or “LIFO” method) or market value. The Company periodically reviews its inventory for slow moving or obsolete items and writes down the related products to estimated realizable value. The Company has not established significant reserves for estimated slow moving products or obsolescence. At December 31, 2012, the excess of the replacement cost of inventory over the LIFO value of inventory was approximately $23.7 million. Due to the nature of the LIFO valuation methodology, liquidations of inventories will result in a portion of the Company’s cost of sales being based on historical rather than current year costs.

The majority of the Company’s products are made in a proprietary process that combines waste wood fibers and reclaimed polyethylene. The Company grinds up scrap materials generated from its manufacturing process and inventories deemed no longer salable and reintroduces the “reclaimed” material into the manufacturing process as a substitute for raw materials. The reclaimed material is valued at the costs of the raw material components of the material.

Property, Plant and Equipment

Property, plant and equipment are stated at historical cost. The costs of additions and improvements are capitalized, while maintenance and repairs are expensed as incurred. Depreciation is provided using the straight-line method over the following estimated useful lives:


Buildings			40 years
Machinery and equipment			5-11 years
Furniture and equipment			10 years
Forklifts and tractors			5 years
Computer equipment and software			3-5 years

Leasehold improvements are amortized over the shorter of the lease term or the estimated useful life of the asset.

The Company reviews its long-lived assets, including property, plant and equipment, whenever events or changes in circumstances indicate that the carrying amount of the assets may not be fully recoverable. To determine the recoverability of its long-lived assets, the Company evaluates the probability that future estimated undiscounted net cash flows will be less than the carrying amount of the long-lived assets. If the estimated cash flows are less than the carrying amount of the long-lived assets, the assets are written down to their fair value. The Company’s estimates of anticipated cash flows and the remaining estimated useful lives of long-lived assets could be reduced in the future. As a result, the carrying amount of long-lived assets could be reduced in the future.

Contract Termination Costs

In anticipation of relocating its corporate headquarters, the Company entered into a lease agreement in 2005. The Company reconsidered and decided not to move its headquarters. The lease, which began on January 1, 2006 and extends through June 30, 2019, obligates the Company to lease 55,047 square feet. The Company has executed subleases for the entire 55,047 square feet it currently leases. The terms of the existing subleases expire in years 2013 to 2019. The Company estimates that the present value of the estimated future sublease rental receipts, net of transaction costs, will be less than the Company’s remaining minimum lease payment obligations under its lease for the office space and have recorded a liability for the expected shortfall.

To estimate future sublease receipts for the periods beyond the term of the existing subleases, the Company has assumed that the existing subleases will be renewed or new subleases will be executed at rates consistent with rental rates in the current subleases. However, management cannot be certain that the timing of future subleases or the rental rates contained in future subleases will not differ from current estimates. Factors such as the availability of commercial office space, economic conditions and subtenant preferences will influence the terms achieved in future subleases. The inability to sublet the office space in the future or unfavorable changes to key management assumptions used in the estimate of the future sublease receipts may result in material charges to selling, general and administrative expenses in future periods.

Goodwill

Goodwill represents the excess of cost over net assets acquired resulting from the Company’s 1996 purchase of the Mobil Composite Products Division and the 2011 purchase of the assets of the Iron Deck Corporation. The Company evaluates the recoverability of goodwill annually or more frequently if an event occurs or circumstances change in the interim that would more likely than not reduce the fair value of the asset below its carrying amount. Goodwill is considered to be impaired when the net book value of the reporting unit exceeds its estimated fair value.

In the evaluation of goodwill for impairment, the Company first compares the fair value of the reporting unit to its carrying value. If the carrying value of a reporting unit exceeds its fair value, the goodwill of that reporting unit is potentially impaired and step two of the impairment analysis is performed. In step two of the analysis, an impairment loss is recorded equal to the excess of the carrying value of the reporting unit’s goodwill over its implied fair value should such a circumstance arise.

The Company measures fair value of the reporting unit based on a present value of future discounted cash flows and a market valuation approach. The discounted cash flows model indicates the fair value of the reporting unit based on the present value of the cash flows that the reporting unit is expected to generate in the future. Significant estimates in the discounted cash flows model include: the weighted average cost of capital; long-term rate of growth and profitability of the business; and working capital effects. The market valuation approach indicates the fair value of the business based on a comparison of the Company against certain market information. Significant estimates in the market approach model include identifying appropriate market multiples and assessing earnings before interest, income taxes, depreciation and amortization (EBITDA) in estimating the fair value of the reporting unit.

For the years ended December 31, 2012, 2011 and 2010, the Company completed its annual impairment test of goodwill and noted no impairment. The Company performs the annual impairment testing of its goodwill as of October 31 of each year. However, actual results could differ from the Company’s estimates and projections, which would affect the assessment of impairment. As of December 31, 2012, the Company had goodwill of $10.5 million that is subject to at least annual review of impairment.

Product Warranty

The Company warrants that its products will be free from material defects in workmanship and material and will not check, split, splinter, rot or suffer structural damage from termites or fungal decay. This warranty extends for a period of 25 years for residential use and 10 years for commercial use. With respect to the Company’s Transcend ^®, Enhance^® and Universal Fascia product, the Company further warrants that the product will not fade in color more than a certain amount and will be resistant to permanent staining from food substances or mold (provided the stain is cleaned within seven days of appearance). This warranty extends for a period of 25 years for residential use and 10 years for commercial use. If there is a breach of such warranties, the Company has an obligation either to replace the defective product or refund the purchase price. The Company establishes warranty reserves to provide for estimated future expenses as a result of product defects that result in claims. Reserve estimates are based on management’s judgment, considering such factors as cost per claim, historical experience, anticipated rates of claims, and other available information. Management reviews and adjusts these estimates, if necessary, on a quarterly basis based on the differences between actual experience and historical estimates.

Revenue Recognition

The Company recognizes revenue when title is transferred to customers, which is generally upon shipment of the product to the customer. The Company does not grant contractual product return rights to customers other than pursuant to its product warranty. The Company does not expect future product returns to be material and, consequently, does not maintain an allowance for product returns.

The Company records all shipping and handling fees in sales and records all of the related costs in cost of sales. The Company offers several sales incentive programs to dealers and distributors, including rebates, pricing discounts, favorable payment terms and cooperative advertising, many of which result in cash consideration made to dealers and distributors. The Company accounts for consideration made pursuant to these programs in accordance with accounting guidance that governs consideration given by a vendor to a customer. With the exception of cooperative advertising, the Company classifies sales incentives as a reduction in revenue in “Net sales.” Sales incentives are recorded in the period in which they are earned by customers. The Company’s cooperative advertising program meets the requirements for exclusion from net sales and the costs are recorded as expenses in “Selling, general and administrative expenses” in the accompanying consolidated statements of comprehensive income. Cooperative advertising costs are accrued as incurred.

Stock-Based Compensation

The Company recognizes share-based compensation at the grant date of the award based on the fair value, and is recognized on a straight line basis as expense in the accompanying consolidated statements of comprehensive income over the vesting periods of the award, net of an estimated forfeiture rate.

Income Taxes

The Company accounts for income taxes and the related accounts in accordance with FASB ASC Topic 740, “Income Taxes”. Deferred tax liabilities and assets are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted rates expected to be in effect during the year in which the differences reverse. Management periodically assesses the likelihood that the Company will be able to recover its deferred tax assets and reflects any changes in estimates in the valuation allowance. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion, or all, of the deferred tax asset will not be realized. At December 31, 2012, the Company had a valuation allowance of $24.1 million primarily attributable to the uncertainty related to the realizability of its deferred tax assets. The Company considered all available evidence, both positive and negative, in determining the need for a valuation allowance. Based upon this analysis, including a consideration of the Company’s cumulative loss history in the three-year period ended December 31, 2012, management determined that it is not more likely than not that its deferred tax assets will be realized.

Research and Development Costs

Research and development costs are expensed as incurred. For the years ended December 31, 2012, 2011 and 2010, research and development costs were $2.9 million, $2.5 million and $1.9 million, respectively, and have been included in “Selling, general and administrative expenses” in the accompanying consolidated statements of comprehensive income.

Advertising Costs

The Company expenses its branding and advertising communication costs as incurred. Significant production costs are deferred and recognized as expense in the period that the related advertisement is first used. At December 31, 2012 and December 31, 2011, $0.6 million and $0.9 million, respectively, were included in prepaid expenses for production costs.

For the years ended December 31, 2012, 2011 and 2010, branding expenses, including advertising expenses as described above, were $20.5 million, $19.4 million and $20.6 million, respectively.

Fair Value of Financial Instruments

The Company considers the recorded value of its financial assets and liabilities, consisting primarily of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, accrued expenses and other current liabilities to approximate the fair value of the respective assets and liabilities at December 31, 2012 and 2011.

Comprehensive Income (Loss)

Comprehensive income (loss) consists of net income (loss) and net unrealized gains and losses on interest rate swap contracts. Amounts related to interest rate swap contracts that were previously included in “Accumulated other comprehensive loss” and reclassified to “Interest expense, net” were immaterial for the years ended December 31, 2011 and 2010.

Investment in Denplax

The Company owns 35% of a joint venture, Denplax, with a Spanish environmental company and an Italian equipment manufacturer to operate a plant in Spain designed to recycle waste polyethylene. Denplax qualifies as a variable interest entity per relevant accounting guidance. Denplax was financed with initial equity contributions from the Company and the other partners and debt financing. The Company is not contingently liable for any of Denplax’s obligations. The Company does not control Denplax and records its proportional 35% share of Denplax’s operating results using the equity method. During 2010, the Company determined that its investment in Denplax and a related note receivable were no longer recoverable and recorded a $2.4 million charge to earnings to fully reserve the equity investment and the note. Both the equity investment and note remain fully reserved as of December 31, 2012.

New Accounting Standards

In June 2011, the FASB issued ASU 2011-05, “Presentation of Comprehensive Income.” ASU 2011-05 requires the components of net income and other comprehensive income to be either presented in one continuous statement, referred to as the statement of comprehensive income, or in two separate, but consecutive statements. An entity is also required to present on the face of the financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement(s) where the components of net income and the components of other comprehensive income are presented. In December 2011, the FASB issued ASU 2011-12, “Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in ASU No. 2011-05,” which defers the effective date for the portion of ASU 2011-05 that pertains to the presentation of reclassification adjustments out of accumulated other comprehensive income. While ASU 2011-05 changes the presentation of comprehensive income, there are no changes to the components that are recognized in net income or other comprehensive income under current accounting guidance. The Company adopted ASU 2011-05 effective January 1, 2012. As this guidance only amends the presentation of the components of comprehensive income, the adoption did not have an impact on the Company’s consolidated financial position or results of operations.

Inventory is stated at the lower of LIFO cost or net realizable value. The Company periodically reviews its inventory for slow moving or obsolete items and writes down the related products to estimated net realizable value.

During the year ended December 31, 2012, due to the liquidation of inventories, a portion of the Company’s cost of sales is based on prior year costs rather than current year costs. As a result, the Company recognized a benefit of $4.5 million in 2012. The effect of the liquidation of inventories in 2011 and 2010 on the Company’s cost of sales was immaterial.

Revolving Credit Facility. On January 6, 2012, the Company entered into an Amended and Restated Credit Agreement (the “Amended Credit Agreement”) with BB&T, as a lender, Administrative Agent, Swing Line Lender, Letter of Credit Issuer and a Collateral Agent; Wells Fargo Capital Finance, LLC (“Wells Fargo”) as a lender and a Collateral Agent; and BB&T Capital Markets (“BB&T Capital”), as Lead Arranger to amend the Credit Agreement. BB&T and Wells Fargo are referenced herein as the “Lenders.” These new agreements replace the previous revolver note, the swing advance note and the letter of credit facility, in their entireties and account for all of the Company’s debt capacity. No additional fees were due or owing as a result of the termination of the previous agreements.

Under the Amended Credit Agreement, the Lenders agreed to provide the Company with one or more revolving loans in a collective maximum principal amount of $100,000,000 (the “Revolver Loans”).

Included within the Revolver Loan limit are sublimits for a Letter of Credit Facility in an amount not to exceed $15,000,000 (the “Letter of Credit Facility”); and Swing Advances in an aggregate principal amount at any time outstanding not to exceed $5,000,000 (the “Swing Advance Loan”). The Revolver Loans, the Letter of Credit Facility and the Swing Advance Loan are collectively referred to herein as the “Loans.” The Loans were obtained for the purpose of raising working capital and refinancing the Company’s existing indebtedness.

The Revolver Loans, the Swing Advances and the Letter of Credit Facility provide the Company, in the aggregate, the ability to borrow a principal amount not to exceed $100,000,000 at any one time outstanding (the “Revolving Loan Limit”) (subject to certain Borrowing Base requirements as described in the Amended Credit Agreement which include limits on Eligible Accounts and Inventory as described in the Amended Credit Agreement and any written agreement which may be executed from time to time by the Company and each of the Collateral Agents). The Company is not obligated to borrow any amount under the Revolving Loan Limit. Within the Revolving Loan Limit, the Company may borrow or repay at any time or from time to time while the Revolving Loans are in effect.

Base Rate Advances (as defined in the Amended Credit Agreement) under the Revolver Loans and the Swing Advances accrue interest at the Base Rate plus the Applicable Margin (as defined in the Amended Credit Agreement) and Euro-Dollar Advances for the Revolver Loans and Swing Advances accrue interest at the Adjusted London InterBank Offered Rate plus the Applicable Margin (as defined in the Amended Credit Agreement). Repayment of all then outstanding principal, interest, fees and costs is due on January 9, 2015.

The Letter of Credit Facility provides that upon the Company’s application, BB&T shall issue to the Company’s credit one or more letters of credit in the aggregate amount of up to $15,000,000, or such lesser amount as may be required by law. The Company shall reimburse BB&T for all amounts payable, including interest, under a Letter of Credit at the earlier of (i) the date set forth in the application or (ii) on business day after the payment under such Letter of Credit by BB&T.

Amounts drawn under the Revolver Loans are subject to a borrowing base consisting of certain accounts receivables, inventories, machinery and equipment and real estate. At December 31, 2012, the Company had $5.0 million of outstanding borrowings under the Revolver Loans and additional available borrowing capacity of approximately $56.7 million.

Compliance with Debt Covenants and Restrictions. The Company’s ability to make scheduled principal and interest payments, borrow and repay amounts under any outstanding revolving credit facility, and continue to comply with any loan covenants depends primarily on the Company’s ability to generate sufficient cash flow from operations. To remain in compliance with financial covenants in the Amended Credit Agreement, the Company is required to maintain specified financial ratios based on levels of debt, capital, net worth, fixed charges, and earnings (excluding extraordinary gains and extraordinary non-cash losses) before interest, taxes, depreciation and amortization, all of which are subject to the risks of the business, some of which are discussed in this report under “Risk Factors.” The Company was in compliance with all covenants contained in the Loans at December 31, 2012. Under the Amended Credit Agreement, the material financial covenants and restrictions are as follows:

(a)

Minimum Consolidated Net Worth. The Company agreed that it will maintain Consolidated Net Worth, measured as of the end of each Fiscal Quarter, commencing with the Fiscal Quarter ended December 31, 2011, of not less than $85,000,000.

(b)

Fixed Charge Coverage Ratio. The Company agreed that it will not permit the Fixed Charge Coverage Ratio to be less than 1.15 to 1.0, measured as of the end of each Fiscal Quarter, commencing with the Fiscal Quarter ended December 31, 2011.

(c)

Consolidated Debt to Consolidated EBITDA Ratio. The Company agreed that it will not permit the Consolidated Debt to Consolidated EBITDA Ratio to exceed 3.5 to 1.0 measured as of the end of each Fiscal Quarter (and in the case of Consolidated EBITDA, for the four-quarter period ending on such date) after the date on which the Senior Subordinated Notes have been redeemed in full.

Failure to comply with the financial covenants in the Amended Credit Agreement could be considered a default of the Company’s repayment obligations and, among other remedies, could accelerate payment of any amounts outstanding under the Amended Credit Agreement.

Long-Term Debt. The Company’s convertible notes have been reduced by debt discount of $5.5 million as of December 31, 2011 in accordance with the terms of ASC 470-20.

Long-term debt consists of the following as of December 31 (in thousands):

Stock-Based Compensation

Stock-Based Compensation [Abstract]

STOCK-BASED COMPENSATION

8.	STOCK-BASED COMPENSATION

The Company has one stock-based compensation plan, the 2005 Stock Incentive Plan (the “2005 Plan”), which was amended by its shareholders on May 7, 2008. The 2005 Plan is administered by the Compensation Committee of the Company’s Board of Directors. Stock-based compensation is granted to officers, directors and certain key employees in accordance with the provisions of the 2005 Plan. The 2005 Plan provides for grants of stock options, stock appreciation rights (“SARs”), restricted stock and performance share awards. The total aggregate number of shares of the Company’s common stock that may be issued under the 2005 Plan is 3,150,000 shares. For the years ended December 31, 2012, 2011 and 2010, stock compensation expense related to awards under the 2005 Plan was $3.5 million, $3.1 million and $3.6 million, respectively. This expense is included in “Selling, general and administrative expenses” in the accompanying consolidated statements of comprehensive income.

Stock Options and Stock Appreciation Rights

The 2005 Plan authorizes the grant of stock options and SARs. Stock options are granted with an exercise price and SARs are granted with a grant price equal to the closing market price of the Company’s common stock on the date of grant. These awards have ten-year contractual terms and vest based on the terms of the individual awards. The options and SARs are generally forfeitable upon termination of a holder’s service as an employee or director, unless the individual’s service is terminated due to retirement, death or permanent disability. The Company recognizes compensation cost on a straight-line basis over the vesting period for the award. Prior to 2006, the Company granted stock options and all stock options outstanding at December 31, 2012 are fully vested. In 2006, the Company began the use of SARs instead of stock options.

As of December 31, 2012, there was $1.3 million of unrecognized compensation cost related to SARs expected to be recognized over a weighted-average period of approximately 1.7 years. The fair value of each stock option award and SAR is estimated on the date of grant using a Black-Scholes option-pricing model. For SARs issued in the years ended December 31, 2012, 2011 and 2010, respectively, the assumptions shown in the following table were used:


	Year Ended December 31,
	2012			2011			2010
Dividend yield		0	%		0	%		0	%
Average risk-free interest rate		0.8	%		2.0	%		2.6	%
Expected term (years)		5			5			5
Volatility		65.9	%		65.0	%		66.3	%

Expected Volatility. Volatility is a measure of the amount by which a financial variable such as a share price has fluctuated (historical volatility) or is expected to fluctuate (expected volatility) during a period. The Company has used the historical volatility over the average expected term of the options granted as the expected volatility.

Risk-Free Interest Rate. This is the U.S. Treasury rate having a term that most closely resembles the expected term of the option.

Expected Term. The expected term is the period of time that the SARs granted is expected to remain unexercised. SARs granted during the year ended December 31, 2012 had a maximum term of ten years. The Company used historical exercise behavior with further consideration given to the class of employees to whom the equity awards were granted to estimate the expected term of the SAR.

The forfeiture rate is the estimated percentage of equity awards granted that are expected to be forfeited or canceled before becoming fully vested. The Company estimates forfeitures based on historical experience with further consideration given to the class of employees to whom the equity awards were granted.

The weighted-average grant date fair value of SARs granted during the year ended December 31, 2012 was $25.75.

Stock option activity under the 2005 Plan and a predecessor stock incentive plan is as follows:

Restricted Stock

The fair value of the restricted stock is determined based on the closing price of the Company’s shares on the grant date. Shares of restricted stock vest based on the terms of the awards. Unvested restricted stock is generally forfeitable upon termination of a holder’s service as an employee, unless the individual’s service is terminated due to retirement, death or permanent disability. In the years ended December 31, 2012, 2011 and 2010, 156,927, 67,945 and 91,845 restricted shares were granted at $27.18, $25.86 and $17.41 per share, respectively. The total fair value of restricted shares vested for the years ended December 31, 2012, 2011 and 2010 was $2.5 million, $4.1 million, and $2.7 million, respectively. In the years ended December 31, 2012, 2011 and 2010, $2.0 million, $1.6 million and $1.7 million of compensation expense, respectively, was recognized related to restricted stock awards. At December 31, 2012, there was $3.9 million of total compensation expense related to unvested restricted stock remaining to be recognized over a weighted-average period of approximately 2.6 years. Compensation expense related to restricted stock is included in “Selling, general and administrative expenses” in the accompanying consolidated statements of comprehensive income.

Employee Stock Purchase Plan

The Company has an employee stock purchase plan (“ESPP”) that permits eligible employees to purchase shares of common stock of the Company at a purchase price which is the lesser of 85% of the market price on either the first day of the calendar quarter or the last day of the calendar quarter. Eligible employees may elect to participate in the plan by authorizing payroll deductions from 1% to 15% of gross compensation for each payroll period. On the last day of each quarter, each participant’s contribution account is used to purchase the maximum number of whole shares of common stock determined by dividing the contribution account’s balance by the purchase price. The aggregate number of shares of common stock that may be purchased under the plan is 300,000. Through December 31, 2012, employees had purchased approximately 194,000 shares under the plan. In the years ended December 31, 2012, 2011 and 2010, compensation expense of $65.3 thousand, $86.3 thousand and $52.1 thousand, respectively, was recognized related to the discount on ESPP purchases. Compensation expense related to ESPP purchases is included in “Selling, general and administrative expenses” in the accompanying consolidated statements of comprehensive income.

Gross deferred tax liabilities		(20,758	)		(23,695	)

Net deferred tax asset (liability)	$	(3,561	)	$	(2,943	)

The valuation allowance as of December 31, 2012 of $24.1 million is primarily attributable to the uncertainty related to the realizability of the Company’s deferred tax assets. The Company has considered all available evidence, both positive and negative, in determining the need for a valuation allowance. Based upon this analysis, including a consideration of the Company’s cumulative loss history in the three-year period ended December 31, 2012, management determined that it is not more likely than not that its deferred tax assets will be realized. The Company’s future realization of its deferred tax assets ultimately depends on the existence of sufficient taxable income in the carry-forward periods under the tax laws. The Company will analyze its position in subsequent reporting periods, considering all available positive and negative evidence, in determining the expected realization of its deferred tax assets.

The Company has federal net operating losses of $40.9 million at December 31, 2012 which expire starting 2027.

As of December 31, 2012, the Company has effectively eliminated all unrecognized tax benefits. The following table illustrates changes to recorded unrecognized tax benefits for the years ended December 31, 2012, 2011 and 2010 (in thousands):


	Year Ended December 31,
	2012			2011			2010
Unrecognized tax benefits balance at January 1	$	60		$	3,126		$	3,752
Gross increases related to prior year tax positions		—			1			—
Gross decreases related to prior year tax positions		(36	)		(2,760	)		—
Settlements		(22	)		(245	)		(609	)
Lapse of statute of limitations		(2	)		(62	)		(17	)

Unrecognized tax benefits balance at December 31	$	—		$	60		$	3,126

The Company recognizes interest and penalties related to tax matters as a component of “Selling, general and administrative expenses” in the accompanying consolidated statements of comprehensive income. As of December 31, 2012 and December 31, 2011, the Company had no material amounts accrued for interest or penalties related to uncertain tax positions.

The Company operates in multiple tax jurisdictions and, in the normal course of business, its tax returns are subject to examination by various taxing authorities. Such examinations may result in future assessments by these taxing authorities and the Company has accrued a liability when it believes that it is not more likely than not that it will realize the benefits of tax positions that it has taken or for the amount of any tax benefit that exceeds the cumulative probability threshold in accordance with ASC 740. The Company believes that adequate provisions have been made for all tax returns subject to examination.

COMMITMENTS AND CONTINGENCIES

Legal Matters

On January 19, 2009, a purported class action case was commenced against the Company in the Superior Court of California, Santa Cruz County, by the lead law firm of Lieff, Cabraser, Heimann & Bernstein, LLP and certain other law firms (the “Lieff Cabraser Group”) on behalf of Eric Ross and Bradley S. Hureth and similarly situated plaintiffs. These plaintiffs generally allege certain defects in the Company’s products, and that the Company has failed to provide adequate remedies for defective products. On February 13, 2009, the Company removed this case to the United States District Court, Northern District of California. On January 21, 2009, a purported class action case was commenced against the Company in the United States District Court, Western District of Washington by the law firm of Hagens Berman Sobol Shapiro LLP (the “Hagens Berman Firm”) on behalf of Mark Okano and similarly situated plaintiffs, generally alleging certain product defects in the Company’s products, and that the Company has failed to provide adequate remedies for defective products. This case was transferred by the Washington Court to the California Court as a related case to the Lieff Cabraser Group’s case.

On July 30, 2009, the U.S. District Court for the Northern District of California preliminarily approved a settlement of the claims of the lawsuit commenced by the Lieff Cabraser Group involving surface flaking of the Company’s product, and on March 15, 2010, it granted final approval of the settlement. On April 14, 2010, the Hagens Berman Firm filed a notice to appeal the District Court’s ruling to the United States Court of Appeals for the Ninth Circuit. On July 9, 2010, the Hagens Berman Firm dismissed their appeal, effectively making the settlement final.

On March 25, 2010, the Lieff Cabraser Group amended its complaint to add claims relating to alleged defects in the Company’s products and alleged misrepresentations relating to mold growth. The Hagens Berman firm has alleged similar claims in its original complaint. In its Final Order approving the surface flaking settlement, the District Court consolidated these pending actions relating to the mold claims, and appointed the Hagens Berman Firm as lead counsel in this case.

On December 15, 2010, a purported class action case was commenced against the Company in the United States District Court, Western District of Kentucky, by the lead law firm of Cohen & Malad, LLP (“Cohen & Malad”) on behalf of Richard Levin and similarly situated plaintiffs, and on June 13, 2011, a purported class action was commenced against the Company in the Marion Circuit/Superior Court of Indiana by Cohen & Malad on behalf of Ellen Kopetsky and similarly situated plaintiffs. On June 28, 2011, the Company removed the Kopetsky case to the United States District Court, Southern District of Indiana. On August 11, 2011, a purported class action was commenced against the Company in the 50^th Circuit Court for the County of Chippewa, Michigan on behalf of Joel and Lori Peffers and similarly situated plaintiffs. On August 26, 2011, the Company removed the Peffers case to the United States District Court, Western District of Michigan. On April 4, 2012, a purported class action was commenced against the Company in Superior Court of New Jersey, Essex County on behalf of Caryn Borger, M.D. and similarly situated plaintiffs. On May 1, 2012, the Company removed the Borger case to the United States District Court, District of New Jersey. The plaintiffs in these purported class actions generally allege certain defects in the Company’s products and alleged misrepresentations relating to mold growth.

The Company believes that the claims discussed above relating to mold growth are without merit and denies all liability with respect to the facts and claims alleged. However, the Company is aware of the substantial burden, expense, inconvenience and distraction of continued litigation. During the three months ended December 31, 2012, the Company recorded $1.5 million to expense related to these claims. It is reasonably possible that the Company may incur costs in excess of the recorded amounts; however, the Company expects that the total net cost to resolve the lawsuit will not exceed $10 million.

The Company has other lawsuits, as well as other claims, pending against it which are ordinary routine litigation and claims incidental to the business. Management has evaluated the merits of these other lawsuits and claims, and believes that their ultimate resolution will not have a material effect on the Company’s consolidated financial condition, results of operations, liquidity or competitive position.

Purchase Commitments

The Company fulfills requirements for raw materials under both purchase orders and supply contracts. In the year ended December 31, 2012, the Company purchased substantially all of its waste wood fiber requirements under purchase orders, which do not involve long-term supply commitments. Substantially all of the Company’s PE material purchases are under short-term supply contracts that average approximately two years, for which pricing is negotiated as needed. The PE material supply contracts have not had a material adverse effect on the Company’s business.

The waste wood and PE material supply contracts generally provide that the Company is obligated to purchase all of the waste wood or PE material a supplier provides, if the waste wood or PE material meets certain specifications. The amount of waste wood and PE material the Company is required to purchase under these contracts varies with the production of its suppliers and, accordingly, is not fixed or determinable. As of December 31, 2012, the Company has purchase commitments under waste wood and PE material supply contracts of $18.5 million, $8.6 million, $0.5 million and $12 thousand for the years ending December 31, 2013, 2014, 2015 and 2016, respectively.

The Company outsources the production of certain products to third-party manufacturers under supply contracts that commit the Company to purchase minimum levels for each year extending through 2015. The Company has purchase commitments under the third-party manufacturing contracts of $7.3 million, $4.4 million, and $1.9 million for the years ending December 31, 2013, 2014 and 2015, respectively.

Contract Termination Costs

In anticipation of relocating the Company’s corporate headquarters, the Company entered into a lease agreement in 2005. The Company reconsidered and decided not to move its headquarters. The lease, which began on January 1, 2006 and extends through June 30, 2019, obligates the Company to lease 55,047 square feet. The Company has executed subleases for the entire 55,047 square feet it currently leases. The terms of the existing subleases expire in years 2013 to 2019. The Company estimates that the present value of the estimated future sublease rental receipts, net of transaction costs, will be less than the Company’s remaining minimum lease payment obligations under its lease for the office space and has recorded a liability for the expected shortfall.

To estimate future sublease receipts for the periods beyond the term of the existing subleases, the Company has assumed that the existing subleases will be renewed or new subleases will be executed at rates consistent with rental rates in the current subleases. However, management cannot be certain that the timing of future subleases or the rental rates contained in future subleases will not differ from current estimates. Factors such as the availability of commercial office space, poor economic conditions and subtenant preferences will influence the terms achieved in future subleases. The inability to sublet the office space in the future or unfavorable changes to key management assumptions used in the estimate of the future sublease receipts may result in material charges to selling, general and administrative expenses in future periods.

As of December 31, 2012, the minimum payments remaining under the Company’s lease over the years ending December 31, 2013, 2014, 2015, 2016, and 2017 are $1.7 million, $1.7 million, $1.7 million, $1.8 million and $1.8 million, respectively, and $2.7 million thereafter. The minimum receipts remaining under the Company’s existing subleases over the years ending December 31, 2013, 2014, 2015, 2016, and 2017 are $1.5 million, $1.5 million, $0.6 million, $0.6 million and $0.6 million, respectively, and $1.0 million thereafter. As a result of new leases executed with subtenants, the Company recognized an increase in estimated contract termination costs of $0.7 million during the year ended December 31, 2012.

The following table provides information about the Company’s liability under the lease (in thousands):


	2012			2011
Balance as of January 1,	$	452		$	567
Net rental receipts (payments)		(115	)		(161	)
Accretion of discount		39			46
Increase in net estimated contract termination costs		727			—

Balance as of December 31,	$	1,103		$	452

Product Warranty

The Company continues to receive and settle claims related to material produced at its Nevada facility prior to 2007 that exhibits surface flaking and maintains a warranty reserve to provide for the settlement of these claims. Projecting future surface flaking settlement costs requires management to estimate the number of claims to be received, the number of claims that will ultimately result in payment and the average cost to settle each claim, all of which are subject to variables that are difficult to predict.

The average cost per claim may vary due to a number of factors, including the average size of affected decks, the type of replacement material used, changes in the cost of production and the method of claim settlement. Although the cost per claim varies over time, it is less volatile and more predictable than the number of claims to be received, which is inherently uncertain. The Company is not aware of any analogous industry data that might be referenced in predicting future claims to be received. The Company evaluates its historical surface flaking claims activity in developing its estimate of future claims. The Company anticipated that the effects of a previously settled class action lawsuit would subside and the number of claims received would substantially diminish. Payments for surface flaking claims decreased from $28 million in 2007 to $9 million in 2012, and the number of claims received continues to decline.

During the three months ended September 30, 2012, the Company concluded, based on an analysis of recent claims activity, that the payments for surface flaking claims and the rate of decline in claims in 2012 would approximate the levels experienced in 2011, falling short of the Company’s estimated decline. As a result, the Company revised its estimate of the future claims to be received to reflect a rate of decline consistent with the trend emerging from the claims activity. The effect of reducing the anticipated rate of decline both increases the number of claims expected in future years and extends the number of years in which claims will be received. As a result of these changes in estimate, the Company recorded an increase to the warranty reserve of $20 million during the three months ended September 30, 2012, and $21.5 million for the year ended December 31, 2012.

The Company’s analysis is based on currently known facts and a number of assumptions. However, projecting future events such as new claims to be received each year and the average cost of resolving each claim could cause the actual warranty liabilities to be higher or lower than those projected which could materially affect our financial condition, results of operations or cash flow. The Company estimates that the number of claims received will continue to decline over time. If the level of claims does not diminish consistent with the Company’s expectations, it could result in additional increases to the warranty reserve and reduced earnings in future periods. The Company estimates that a 10% change in the expected number of remaining claims or the expected cost to settle claims may result in approximately a $3.0 million change in the warranty reserve.

The following is a reconciliation of the Company’s warranty reserve (in thousands):


	2012			2011
Beginning balance, January 1	$	16,345		$	14,472
Provision for estimated warranties		21,487			9,976
Settlements made during the period		(8,845	)		(8,103	)

Ending balance, December 31	$	28,987		$	16,345

The Company’s net sales, gross profit and income from operations have historically varied from quarter to quarter. Such variations are principally attributable to seasonal trends in the demand for Trex. The Company has historically experienced lower net sales during the fourth quarter because holidays and adverse weather conditions in certain regions reduce the level of home improvement and new construction activity.

(a)	Three months ended September 30, 2012 was materially affected by a pre-tax increase of $20.0 million to the warranty reserve.

(b)	Three months ended December 31, 2011 was materially affected by a pre-tax increase of $10.0 million to the warranty reserve.

- Definition

- Definition

The estimated measure of the percentage by which a share price is expected to fluctuate during a period. Volatility also may be defined as a probability-weighted measure of the dispersion of returns about the mean. The volatility of a share price is the standard deviation of the continuously compounded rates of return on the share over a specified period. That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period.
