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. The consolidated financial statements include the accounts of the Company. Intercompany accounts and transactions have been eliminated in consolidation. The Company’s results of operations are affected by a number of factors, including, but not limited to, the cost to manufacture and distribute products, cost of raw materials, inflation, tariffs, consumer spending and preferences, interest rates, the impact of any supply chain disruptions, economic conditions, and/or any adverse effects from global health pandemics and geopolitical conflicts. 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 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, 2024 , 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 recognized at the amount of revenue recognized on each shipment for Trex Residential products as the Company has an unconditional right to consideration from the customer and payment is due based solely on the passage of time. An estimate of expected credit losses is recognized as a valuation allowance and adjusted each reporting period. The estimate is based on the current expected credit loss model and is determined using an aging schedule, including past events, current conditions and reasonable and supportable forecasts about the future. There was no material valuation allowance recorded as of December 31, 2024 and December 31, 2023. In the years ended December 31, 2024 , 2023, and 2022, sales to certain customers of Trex Residential accounted for 10 % or more of the Company’s total net sales. For the year ended December 31, 2024 , three customers of Trex Residential represented approximately 81 % of the Company’s total net sales. For the year ended December 31, 2023 , three customers of Trex Residential represented 72 % of the Company’s total net sales. For the year ended December 31, 2022 , three customers of Trex Residential represented approximately 64 % of the Company’s total net sales. No other customer represented 10% or more of the Company’s total net sales. At December 31, 2024 , two customers represented 33 %, and 32 %, respectively, of the Company’s total accounts receivable balance. At December 31, 2023 , three customers represented 27 %, 23 % and 20 %, respectively, of the Company’s total accounts receivable balance. For each year ended December 31, 2024 , 2023, and 2022, approximately 21.4 %, 26.7 %, and 17.5 %, respectively, of the Company’s materials purchases at Trex Residential were purchased from its four largest suppliers. Inventories Inventories for the composite decking and railing products at Trex Residential are valued at the lower of cost (last-in, first-out, or LIFO, method) and market as this method results in a better matching of costs and revenues. The Company periodically reviews its inventory for slow moving or obsolete items and writes down the related products to the lower of cost or market. The Company’s reserves for estimated slow moving products or obsolescence are not material. At December 31, 2024 , the excess of the replacement cost of inventory over the LIFO value of inventory was approximately $ 49.7 million. Due to the nature of the LIFO valuation methodology, liquidations of inventories result in a portion of the Company's cost of sales being based on historical rather than current year costs. There were no LIFO liquidations or related impact on cost of sales in 2024. A majority of the products at Trex Residential are made in a proprietary process that combines reclaimed wood fibers and scrap polyethylene. Trex Residential 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. Cash flows for capital expenditures as reported in cash flows from investing activities in the Consolidated Statements of Cash Flows are adjusted to exclude unpaid amounts accrued at period end. Depreciation is provided using the straight-line method generally over the following estimated useful lives: Buildings 40 years Machinery and equipment 3 - 11 years Furniture and fixtures 10 years Forklifts and tractors 5 years Computer equipment and software 5 years Leasehold improvements are amortized over the shorter of the lease term or 15 years. 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. Long-lived assets held for sale are stated at the lower of cost or fair value less cost to sell. Leases The Company leases office space, storage warehouses, training and manufacturing facilities, and certain office and plant equipment under various operating leases. At inception of an arrangement, the Company evaluates, among other things, whether it has the right to control the use of an identified asset in order to determine if the arrangement is or contains a lease. Operating leases are included in operating lease right-of-use (ROU) assets, accrued expenses and other current liabilities, and operating lease liabilities in the consolidated balance sheets. Operating leases with an initial term of 12 months or less are not included in the consolidated balance sheet. The Company recognizes lease expense for these leases on a straight-line basis over the lease term. ROU assets represent the right to use an underlying asset for the lease term and operating lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the implicit rates of the Company’s leases are not readily determinable, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The Company considers instruments with similar characteristics when calculating its incremental borrowing rate. Certain events, such as a modification to the arrangement or a change in the lease term, are assessed by the Company to determine if it is required to reassess estimates and judgments and remeasure the lease liability and ROU asset. The Company reviews its ROU asset for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be fully recoverable. The carrying amount of the ROU asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use of the asset. An impairment loss is measured as the amount by which the carrying amount of the ROU asset exceeds its fair value. The Company’s operating leases have remaining lease terms up to 11 years . Lease terms may include options to extend or terminate the lease when the Company determines that it is reasonably certain it will exercise the option. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are accounted for separately. Consideration for non-lease components is stated on a stand-alone basis in the applicable agreements. Fair Value Measurement Assets and liabilities measured at fair value are measured at the amount that would be received for selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and classified into one of the following fair value hierarchies: • Level 1 – Quoted prices for identical instruments in active markets. • Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model derived valuations in which all significant inputs and significant value drivers are observable in active markets. • Level 3 – Valuations derived from management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. Goodwill Goodwill represents the excess of cost over net assets acquired resulting from the Company’s 1996 purchase of the Mobil Composite Products Division, the 2011 purchase of the assets of the Iron Deck Corporation, and the 2017 purchase of certain assets and the assumption of certain liabilities of SC Company. The Company evaluates the recoverability of goodwill in accordance with Accounting Standard Codification Topic 350, “ Intangibles – Goodwill and Other ,” 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. The Company assigned its goodwill to reporting units and tests each reporting unit’s goodwill for impairment at least on an annual basis, or more frequently if an event occurs or circumstances change in the interim that indicate the carrying amount of reporting unit goodwill exceeds the implied fair value of that goodwill. The Company identified its reporting units based on the way it manages its operating segments. Prior to December 30, 2022, the Company had three reporting units: a residential reporting unit in the Trex Residential reportable segment, and a commercial railing reporting unit and a staging reporting unit in the Trex Commercial reportable segment. Subsequent to the sale of Trex Commercial on December 30, 2022, the Company has one reporting unit in the Trex Residential reportable segment. Each reporting unit constitutes a business with discrete financial information and operating segment management, at a level below the Company’s chief operating decision maker regularly reviews the operating results of the reporting unit. The Company assigned goodwill to the reporting units based on the excess of the fair values acquired over the fair value of the sum of the individual assets acquired and liabilities assumed that were assigned to the reporting units. In testing for goodwill impairment, the Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. If the qualitative assessment indicates that the carrying amount of the reporting unit exceeds its fair value, including goodwill, the Company is then required to perform a quantitative goodwill impairment test. The quantitative goodwill impairment test, used to identify both the existence of impairment and the amount of impairment loss, compares the fair value of a reporting unit with its carrying amount, including goodwill. The fair value of a reporting unit refers to the price that would be received to sell the unit as a whole in an orderly transaction between market participants at the measurement date. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. The Company performs the annual impairment testing of its goodwill as of October 31 of each year. For fiscal years 2024, 2023 and 2022, the Company completed its annual impairment test of goodwill for its Trex Residential reporting segment residential reporting unit utilizing the qualitative assessment and concluded it was not more likely than not that the fair value of the residential reporting unit was less than its carrying amount. Qualitative factors the Company considered include events and circumstances such as macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, and other relevant Company-specific events, as applicable. Product Warranty The Company warrants that for the applicable warranty period its Trex Residential products, when properly installed, used and maintained, will be free from material defects in workmanship and materials and its decking, cladding, fascia and railing products will not split, splinter, rot or suffer structural damage from termites or fungal decay. Products sold on or after January 1, 2023: The warranty period for residential use is 50 years for Transcend ® decking, 35 years for Select ® decking and Universal Fascia, and 25 years for Enhance ® decking and Transcend, Select, Enhance and Signature ® railing. The warranty period for commercial use is 10 years, excluding Signature railing and Transcend cladding, which each have a warranty period of 25 years. The Company further warrants that Trex Transcend, Trex Enhance and Trex Select decking and cladding and Universal Fascia products will not fade in color from light and weathering exposure more than a certain amount and will be resistant to permanent staining from food and beverage substances or mold and mildew, provided the stain is cleaned within seven days of appearance, for the warranty period referred to above. If there is a breach of such warranties, the Company has an obligation either to replace the defective product or refund the purchase price. Products sold prior to January 1, 2023: The warranty period is 25 years for residential use and 10 years for commercial use. With respect to Trex Signature railing, the warranty period is 25 years for both residential and commercial use. The Company further warrants that Trex Transcend, Trex Enhance, Trex Select and Universal Fascia products 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, for the warranty period referred to above. 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 maintains a warranty reserve for the settlement of its product warranty claims. The Company accrues for the estimated cost of product warranty claims at the time revenue is recognized based on such factors as historical claims experience and expected future claims experience. Management reviews and adjusts these estimates, if necessary, based on the differences between actual experience and historical estimates. Additionally, the Company accrues for warranty costs associated with occasional or unanticipated product quality issues if a loss is probable and can be reasonably estimated, as necessary. Treasury Stock The Company records the repurchase of shares of its common stock at cost. These shares are considered treasury stock, which is a reduction to stockholders’ equity. Treasury stock is included in authorized and issued shares but excluded from outstanding shares. Revenue Recognition Trex Residential Products. Trex Residential principally generates revenue from the manufacture and sale of its high-performance, low-maintenance, eco-friendly composite decking and railing products and accessories. Substantially all of its revenues are from contracts with customers, which are individual customer purchase orders of short-term duration of less than one year. Trex Residential satisfies its performance obligations at a point in time. The shipment of each product is a separate performance obligation as the customer is able to derive benefit from each product shipped and no performance obligation remains after shipment. Upon shipment of the product, the customer obtains control over the distinct product and Trex Residential satisfies its performance obligation. Any performance obligation that remains unsatisfied at the end of a reporting period is part of a contract that has an original expected duration of one year or less. Any variable consideration related to the unsatisfied performance obligation is allocated wholly to the unsatisfied performance obligation and recognized when the product ships and the performance obligation is satisfied and is included in “Accrued expenses and other liabilities, Sales and marketing” in Note 8 to these Consolidated Financial Statements. Trex Commercial Products. Trex Commercial generated revenue from the manufacture and sale of its modular and architectural railing and staging systems. All of its revenues were from fixed-price contracts with customers. Trex Commercial contracts had a single performance obligation as the promise to transfer the individual goods or services was not separately identifiable from other promises in the contract and was, therefore, not distinct. On December 30, 2022, the Company sold substantially all of the assets of its wholly-owned subsidiary and reportable segment Trex Commercial. Trex Commercial satisfied its performance obligation over time as work progressed because control transferred continuously to its customers. Revenue and estimated profit were recognized over time based on the proportion of actual costs incurred to date relative to total estimated costs at completion to measure progress toward satisfying the performance obligation. Incurred costs represent work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. Incurred costs included all direct material, labor, subcontract and certain indirect costs. The Company reviewed and updated its estimates regularly and recognized adjustments in estimated profit on contracts under the cumulative catch-up method. Under this method, the impact of the adjustment on revenue and estimated profit to date on a contract is recognized in the period the adjustment is identified. If at any time the estimate of contract profitability indicated an anticipated loss on the contract, the Company recognized the total loss in the period it was identified. During the year ended December 31, 2022 , no adjustment to any one contract was material to the Company’s Consolidated Financial Statements and no material impairment loss on any contract was recorded. Stock-Based Compensation The Company measures stock-based compensation at the grant date of the award based on the fair value. For stock options, stock appreciation rights and time-based restricted stock and time-based restricted stock units, stock-based compensation is recognized on a straight-line basis over the vesting periods of the award. The Company recognizes forfeitures as they occur. For performance-based restricted stock and performance-based restricted stock units, expense is recognized ratably over the performance and vesting period of each tranche based on management’s judgment of the ultimate award that is probable to be paid out based on the achievement of predetermined performance measures. Stock-based compensation expense is included in “Selling, general and administrative expenses” in the accompanying Consolidated Statements of Comprehensive Income. Income Taxes The Company recognizes deferred tax assets and liabilities based on the difference between the financial statement basis and tax basis of assets and liabilities using enacted tax laws and statutory tax rates. The Company assesses the likelihood that its deferred tax assets will be realized. Deferred tax assets are reduced by a valuation allowance when, after considering all available positive and negative evidence, it is determined that it is more likely than not that some portion, or all, of the deferred tax asset will not be realized. As of December 31, 2024 , the Company has a valuation allowance of $ 2.6 million against these deferred tax assets related to certain state tax credits. The Company analyzes its position in subsequent reporting periods, considering all available positive and negative evidence, in determining the expected realization of its deferred tax assets. Research and Development Costs Research and development costs are expensed as incurred. For the years ended December 31, 2024 , 2023, and 2022, research and development costs were $ 3.5 million, $ 3.3 million, and $ 0.5 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. Production costs are deferred and recognized as expense in the period that the related advertisement is first used. For the years ended December 31, 2024 , 2023, and 2022, branding expenses, including advertising expenses, were $ 53.5 million, $ 48.8 million, and $ 43.3 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, accounts receivable, accounts payable, accrued expenses and other current liabilities, and debt to approximate the fair value of the respective assets and liabilities on the Consolidated Balance Sheets at December 31, 2024 and 2023. New Accounting Standards Recently Adopted In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” The guidance requires disclosure of significant segment expenses which are regularly provided to the chief operating decision maker (CODM), the composition of and amount of other segment items, the CODM’s title and position within the organization, and how the CODM uses the reported measure(s) of segment’s profit or loss to assess the performance of the segment. In addition, on an interim basis, all segment profit or loss and asset disclosures currently required on an annual basis must be reported, as well as those required by Topic 280. The guidance allows for multiple measure of a segment’s profit or loss to be reported. Entities which have a single reportable segment must apply Topic 280 in its entirety. The guidance was effective for fiscal years beginning after December 15, 2023, and for interim periods beginning after December 15, 2024. Early adoption was permitted. Entities are required to apply the amendments of this update retrospectively for all prior periods presented in the financial statements. The Company adopted the standard in the quarterly period ended December 31, 2024. The Company applied the standard retrospectively and accordingly, prior periods were adjusted. Adoption of this guidance did not impact consolidated results of operations and financial position . New Accounting Standards Not Yet Adopted In November 2024, the FASB issued ASU No. 2024-03, “Income Statement – Reporting Comprehensive Income – Disaggregation Disclosures.” This guidance requires more detailed disclosure about the types of expenses presented within the expense captions of the financial statements. Specifically, disclosure of purchases of inventory, employee compensation, depreciation, and intangible asset amortization are required on both an interim and annual basis. In addition, a qualitative description of remaining amounts in relevant expense captions which have not separately been disaggregated will be required on an interim and annual basis. On an annual basis, disclosure of an entity’s definition of selling expenses and the amount of selling expenses is required. The amendments to this update are effective for annual reporting periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption of this update is permitted. The amendments to this update should be applied prospectively to financial statements issued for reporting periods after the effective date of the update or retrospectively to any or all prior periods presented in the financial statements. The Company believes adoption will result in expanded financial statement footnote disclosure but does not believe adoption of this update will have a material impact on its consolidated results of operations. The Company is continuing to evaluate the impacts of the pending adoption. As such, the Company’s preliminary assessments are subject to change. In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The guidance requires public entities to disclose additional categories of information related to federal, state, and foreign income taxes and additional details related to reconciling items should they meet a quantitative threshold. The guidance requires disclosure of income taxes paid (net of refunds received) disaggregated by federal, state, and foreign taxes and to disaggregate the information by jurisdiction based on quantitative thresholds. The guidance is effective for fiscal year beginning after December 15, 2024. Early adoption is permitted. The guidance should be applied on a prospective basis, retrospective application is permitted. The Company does not expect adoption of the guidance to have a material effect on its consolidated results of operations and financial position. |
