2. | BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and the instructions to Form
10-Q
and Article 10 of Regulation
S-X
and, accordingly, the accompanying unaudited condensed consolidated financial statements do not include all of the information and notes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, all adjustments (consisting of normal and recurring adjustments, except as otherwise described herein) considered necessary for a fair presentation have been included in the accompanying unaudited condensed consolidated financial statements. Certain reclassifications have been made to prior period balances to conform to current year presentation. The unaudited condensed consolidated financial statements include the accounts of the Company for all periods presented. Intercompany accounts and transactions have been eliminated in consolidation.
The unaudited consolidated results of operations for the three and nine months ended September 30, 2022, are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2022. 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, consumer spending and preferences, interest rates, the impact of any supply chain disruptions, economic conditions, and/or any adverse effects from the
COVID-19
pandemic and geopolitical conflicts. Towards the end of June 2022, we experienced a reduction in demand from our distribution partners, which we believe was primarily spurred by concerns over a potential easing in consumer demand due to rising interest rates, declining consumer sentiment and expectations of a general slowing in the economy. As a result, beginning in the third quarter our channel partners met demand partially through inventory drawdown rather than reordering products and maintaining current inventories. The drawdown negatively impacted third quarter sales and will likely impact fourth quarter sales.
These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements as of December 31, 2021, and December 31, 2020, and for each of the three years in the period ended December 31, 2021, included in the Annual Report of Trex Company, Inc. on Form
10-K,
as filed with the U.S. Securities and Exchange Commission.

3. | RECENTLY ADOPTED ACCOUNTING STANDARDS

In November 2021, the FASB issued ASU
No. 2021-10,
“
Government Assistance (Topic 832):
Disclosures by Business Entities about Government Assistance
”. The guidance requires business entities to make annual disclosures about transactions with a government they account for by analogizing to a grant or contribution accounting model, such as IAS 20, ASC
958-605.
The annual disclosure requirements include: the nature of the transactions, the entities related accounting policy used, the line items on the balance sheet and income statement that are affected and the amounts applicable to each financial statement line item, and significant terms and conditions of the transactions. The disclosure requirements could be applied either prospectively to all transactions in the scope of the amendments that are reflected in the financial statements at the date of initial application and new transactions that are entered into after the date of initial application, or retrospectively.

Table of Contents
The guidance was effective for fiscal years beginning after December 15, 2021, with early application permitted. Adoption of the guidance did not have a material effect on the Company’s consolidated financial statements.

4. | NEW ACCOUNTING STANDARDS NOT YET ADOPTED

In March 2020, the FASB issued ASU
No. 2020-04,
“
Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting
”. The guidance provides temporary optional expedients and exceptions related to contract modifications and hedge accounting to ease entities’ financial reporting burdens as the market transitions from the London Interbank Offered Rate and other interbank offered rates to alternative reference rates. The new guidance allows entities to elect not to apply certain modification accounting requirements, if certain criteria are met, to contracts affected by what the guidance calls reference rate reform. An entity that makes this election would consider changes in reference rates and other contract modifications related to reference rate reform to be events that do not require contract remeasurement at the modification date or reassessment of a previous accounting determination. The ASU notes that changes in contract terms that are made to effect the reference rate reform transition are considered related to the replacement of a reference rate if they are not the result of a business decision that is separate from or in addition to changes to the terms of a contract to effect that transition. The guidance is effective upon issuance and generally could be applied as of March 12, 2020, through December 31, 2022. The Company does not expect adoption of the guidance to have a material effect on its consolidated financial statements.

5. | INVENTORIES

Inventories valued at LIFO
(last-in,
first-out),
consist of the following (in thousands):

|  | September 30, 2022 |  |  | December 31, 2021 |
Finished goods |  | $ | 89,551 |  |  | $ | 58,401 |
Raw materials |  |  | 71,092 |  |  |  | 56,441 |
Total FIFO (first-in, first-out) inventories |  |  | 160,643 |  |  |  | 114,842 |
Reserve to adjust inventories to LIFO value |  |  | (36,467 | ) |  |  | (36,467 | )
Total LIFO inventories |  | $ | 124,176 |  |  | $ | 78,375 |

The Company utilizes the LIFO method of accounting related to its Trex Residential wood-alternative decking and residential railing products, which generally provides for the matching of current costs with current revenues. However, under the LIFO method, reductions in annual inventory balances cause a portion of the Company’s cost of sales to be based on historical costs rather than current year costs (LIFO liquidation). Reductions in interim inventory balances expected to be replenished by
year-end
do not result in a LIFO liquidation. Accordingly, interim LIFO calculations are based, in part, on management’s estimates of expected
year-end
inventory levels and costs, which may differ from actual results. Since inventory levels and costs are subject to factors beyond management’s control, interim results are subject to the final
year-end
LIFO inventory valuation. There were no LIFO inventory liquidations or related impact on cost of sales in the nine months ended September 30, 2022.
Inventories valued at lower of cost (FIFO method) and net realizable value were $7.9 million at, September 30, 2022, and $5.4 million at December 31, 2021, consisting primarily of raw materials. The Company utilizes the FIFO method of accounting related to its Trex Commercial products.

7. | GOODWILL AND OTHER INTANGIBLE ASSETS, NET

The carrying amount of goodwill at September 30, 2022, and December 31, 2021, was $14.2 million for Trex Residential. The Company’s intangible assets consist of domain names for Trex Residential. At September 30, 2022, and December 31, 2021, intangible assets were $6.3 million and accumulated amortization was $1.8 million and $1.5 million, respectively. Intangible asset amounts were determined based on the estimated economics of the asset and are amortized over the estimated useful lives on a straight-line basis over 15 years, which approximates the pattern in which the economic benefits are expected to be received. The Company evaluates the recoverability of intangible assets periodically and considers events or circumstances that may warrant revised estimates of useful lives or that may indicate an impairment. Intangible asset amortization expense for the nine months ended September 30, 2022, and September 30, 2021, was $0.3 million and $0.3 million, respectively.

The Base Rate for any day is a fluctuating rate per annum equal to the highest of (a) the Federal Funds Rate plus 0.50%, (b) the rate of interest in effect for such day as publicly announced from time to time by BOA as its prime rate, and (c) the Term SOFR plus 1.0% subject to certain interest rate floors. Repayment of all then outstanding principal, interest, fees and costs is due at the end of the Term.

Diluted earnings per share is computed using the weighted average number of shares determined for the basic earnings per share computation plus the dilutive effect of common stock equivalents using the treasury stock method. The computation of diluted earnings per share excludes the following potentially dilutive securities because the effect would be anti-dilutive:​​​​​​​

|  | Three Months Ended September 30, |  |  | Nine Months Ended September 30, |
|  | 2022 |  |  | 2021 |  |  | 2022 |  |  | 2021 |

Stock Repurchase Program
On February 16, 2018, the Trex Board of Directors adopted a stock repurchase program of up to 11.6 million shares of its outstanding common stock (Stock Repurchase Program). As of September 30, 2022, Trex has repurchased 9.0 million shares of its outstanding common stock under the Stock Repurchase Program.

13. | REVENUE FROM CONTRACTS WITH CUSTOMERS

Trex Residential Products
Trex Residential principally generates revenue from the manufacture and sale of its high-performance,
low-maintenance,
eco-friendly
wood-alternative composite decking and residential railing products and accessories. Substantially all of its revenues are from contracts with customers, which are purchase orders of short-term duration of less than one year. Its customers, in turn, sell primarily to the residential market, which includes replacement, remodeling and new construction related to outdoor living products. 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, is 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 the Condensed Consolidated Financial Statements.
Trex Commercial Products
Trex Commercial generates revenue from the manufacture and sale of its modular and architectural railing and staging systems. All of its revenues are from fixed-price contracts with customers. Trex Commercial contracts have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contract and is, therefore, not distinct. The transaction price allocated to remaining performance obligations on contracts with an original duration greater than one year was $42.5 million as of September 30, 2022. The Company will recognize this revenue as contracts are completed, which is expected to occur within the next 24 months.
For the three months and nine months ended September 30, 2022, and September 30, 2021, net sales were disaggregated in the following tables by (1) market, (2) timing of revenue recognition, and (3) type of contract. The tables also include a reconciliation of the respective disaggregated net sales with the Company’s reportable segments (in thousands).​​​​​​​

14. | STOCK-BASED COMPENSATION

The Company has one stock-based compensation plan, the 2014 Stock Incentive Plan (Plan), approved by Trex stockholders in April 2014. The Plan is administered by the Compensation Committee of the Trex Board of Directors. Stock-based compensation is granted to officers, directors and certain key employees in accordance with the provisions of the Plan. The Plan provides for grants of stock options, restricted stock, restricted stock units, stock appreciation rights (SARs), and unrestricted stock. The total aggregate number of shares of Trex common stock that may be issued under the Plan is 25,680,000 and as of September 30, 2022, the total number of shares available for future issuance is 11,060,097.​​​​​​​

Table of Contents
The following table summarizes the Company’s stock-based compensation grants for the nine months ended September 30, 2022:

|  | Stock Awards Granted |  |  | Weighted-Average Grant Price Per Share |
Time-based restricted stock units |  |  | 56,818 |  |  | $ | 56.18 |
Performance-based restricted stock units (a) |  |  | 72,152 |  |  | $ | 76.14 |
Stock appreciation rights |  |  | 32,971 |  |  | $ | 82.01 |

(a) | Includes 47,072 of target performance-based restricted stock unit awards granted during the nine months ended September 30, 2022, and adjustments of 8,160, 11,684, and 5,236 to grants due to the actual performance level achieved for restricted stock and restricted stock units awarded in 2021, 2020, and 2019, respectively.

The fair value of each SAR is estimated on the date of grant using a Black-Scholes option-pricing formula. For SARs issued in the nine months ended September 30, 2022, and September 30, 2021, the data and assumptions shown in the following table were used:

|  | Nine Months Ended September 30, 2022 |  |  | Nine Months Ended September 30, 2021 |
Weighted-average fair value of grants |  | $ | 33.9 |  |  | $ | 51.84 |
Dividend yield |  |  | 0 | % |  |  | 0 | %
Average risk-free interest rate |  |  | 1.9 | % |  |  | 0.6 | %
Expected term (years) |  |  | 5 |  |  |  | 5 |

16. | SEGMENT INFORMATION

The Company operates in two reportable segments:

| • |  | Trex Residential manufactures wood-alternative decking and residential railing and related products marketed under the brand name Trex ® . Trex Residential products are sold to distributors and home centers for final resale primarily to the residential market, which includes replacement, remodeling and new construction related to outdoor living products.

| • |  | Trex Commercial designs, engineers, and markets modular and architectural railing and staging systems for the commercial and multi-family market, including sports stadiums and performing arts venues. Trex Commercial products are marketed to architects, specifiers, contractors, and others doing business within the commercial and multi-family market.

The Company’s reportable segments have been determined in accordance with its internal management structure, which is organized based on residential and commercial sales activities. The Company evaluates performance of each segment primarily based on net sales and earnings before interest, income taxes, depreciation and amortization (EBITDA). The Company uses net sales to assess performance and allocate resources as this measure represents the amount of business the segment engaged in during a given period of time, is an indicator of market growth and acceptance of segment products and represents the segment’s customers’ spending habits along with the amount of product the segment sells relative to its competitors. The Company uses EBITDA to assess performance and allocate resources because it believes that EBITDA facilitates performance comparison between the segments by eliminating interest, income taxes, and depreciation and amortization charges to income. The below segment data for the three months and nine months ended September 30, 2022 and September 30, 2021 includes data for Trex Residential and Trex Commercial (in thousands):​​​​​​​

17. | SEASONALITY

The operating results for Trex Residential have historically varied from quarter to quarter. Seasonal, erratic or prolonged adverse weather conditions in certain geographic regions reduce the level of home improvement and construction activity and can shift demand for its products to a later period. As part of its normal business practice and consistent with industry practice, Trex Residential has historically offered incentive programs to its distributors and dealers to build inventory levels before the start of the prime deck-building season in order to ensure adequate availability of its product to meet anticipated seasonal consumer demand. The seasonal effects are often offset by the positive effect of the incentive programs. The operating results for Trex Commercial have not historically varied from quarter to quarter as a result of seasonality. However, they are driven by the timing of individual projects, which may vary each quarterly period.

18. | COMMITMENTS AND CONTINGENCIES

Product Warranty
The Company warrants that its decking and residential railing products will be free from material defects in workmanship and materials for warranty periods ranging from 10 years to 25 years, depending on the product and its 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. Depending on the product and its use, the Company also warrants its Trex Commercial products will be free of manufacturing defects for one to three years.
The Company continues to receive and settle claims for products manufactured at its Nevada facility prior to 2007 that exhibit surface flaking and maintains a warranty reserve to provide for the settlement of these claims. Estimating the warranty reserve for surface flaking claims requires management to estimate (1) the number of claims to be settled with payment and (2) the average cost to settle each claim.
To estimate the number of claims to be settled with payment, the Company utilizes actuarial techniques to quantify both the expected number of claims to be received and the percentage of those claims that will ultimately require payment (collectively, elements). Estimates for these elements are quantified using a range of assumptions derived from claim count history and the identification of factors influencing the claim counts. The cost per claim varies due to a number of factors, including the size of affected decks, the availability and type of replacement material used, the cost of production of replacement material and the method of claim settlement.
15

Table of Contents
The Company monitors surface flaking claims activity each quarter for indications that its estimates require revision. Typically, a majority of surface flaking claims received in a year are received during the summer outdoor season, which spans the second and third quarters. It has been the Company’s practice to utilize the actuarial techniques discussed above during the third quarter, after a significant portion of all claims has been received for the fiscal year and variances to annual claims expectations are more meaningful.
The number of incoming claims received in the nine months ended September 30, 2022, was significantly lower than the number of claims received in the nine months ended September 30, 2021 and lower than the Company’s expectations for 2022. Average cost per claim experienced in the nine months ended September 30, 2022 was significantly higher than that experienced in the nine months ended September 30, 2021 and higher than the Company’s expectations for the current year. The elevated average cost per claim experienced in the nine months ended September 30, 2022, was primarily the result of the closure of three large claims, which were considered in the Company’s estimation of its surface flaking warranty reserve. The Company believes its reserve at September 30, 2022 is sufficient to cover future surface flaking obligations.
The Company’s analysis is based on currently known facts and a number of assumptions, as discussed above, and current expectations. Projecting future events such as the number of claims to be received, the number of claims that will require payment and the average cost of claims could cause actual warranty liabilities to be higher or lower than those projected, which could materially affect the Company’s consolidated financial condition, results of operations or cash flows. The Company estimates that the annual number of claims received will decline over time and that the average cost per claim will increase. If the level of claims received or average cost per claim differs materially from expectations, it could result in additional increases or decreases to the warranty reserve and a decrease or an increase in earnings and cash flows in future periods. The Company estimates that a 10% change in the expected number of remaining claims to be settled with payment or the expected cost to settle claims may result in approximately a $1.6 million change in the surface flaking warranty reserve.
The following is a reconciliation of the Company’s residential product warranty reserve (in thousands):

|  | Nine Months Ended September 30, 2022 |
|  | Surface Flaking |  |  | Other Residential |  |  | Total |

Legal Matters
The Company has 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 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.

®
and manufactured in the United States. We offer a comprehensive set of aesthetically appealing and durable,
low-maintenance
product offerings in the decking, residential railing, fencing and outdoor lighting categories. A majority of the products are
eco-friendly
and leverage recycled and reclaimed materials to the extent possible. Trex Residential decking is made in a proprietary process that combines reclaimed wood fibers and recycled polyethylene film, making Trex Residential one of the largest recyclers of plastic film in North America. In addition to resisting fading and surface staining, Trex Residential products require no sanding and sealing, resist moisture damage, provide a splinter-free surface and do not require chemical treatment against rot or insect infestation. Combined, these aspects yield significant aesthetic advantages and lower maintenance than wood decking and railing and ultimately render Trex Residential products less costly than wood over the life of the deck. Special characteristics (including resistance to splitting, the ability to bend, and ease and consistency of machining and finishing) facilitate installation, reduce contractor call-backs and afford consumers a wide range of design options. Trex Residential products are sold to distributors and home centers for final resale primarily to the residential market.

Capital expenditures
. During the 2022 third quarter, our capital expenditures were $41.6 million primarily at Trex Residential related to cost reduction initiatives, the new Arkansas manufacturing facility, capacity expansion in our existing facilities, our new corporate headquarters, and safety, environmental and general support.
Repurchase of common shares
. We repurchased 1.7 million shares of our outstanding common stock in the 2022 third quarter under our Stock Repurchase Program for a total 9.0 million shares repurchased under the program as of September 30, 2022.
RESULTS OF OPERATIONS
General.
Our 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, interest rates, consumer spending and preferences, the impact of any supply chain disruptions, economic conditions, and any adverse effects from the
COVID-19
pandemic and geopolitical conflicts.
Strong sales growth in the first and second quarters of 2022 reflected an increase in Trex Residential net sales driven by pricing actions taken in 2021 and 2022, volume growth that continued to reflect strong secular trends in the outdoor living category, continued execution of our
wood-to-composite
market strategy share conversion, and channel inventory build to support historically high growth rates. The channel inventory build was due in part to expected consumer demand along the lines of what was seen in 2020 and 2021, but also was a consequence of improved product availability following more than two years of capacity constraints and product allocations.
However, towards the end of June Trex Residential experienced a reduction in demand from its distribution partners, spurred by concerns over a potential easing in consumer demand due to rising interest rates, declining consumer sentiment and expectations of a general slowing in the economy. As a result, beginning in the third quarter Trex Residential’s channel partners met demand partially through inventory drawdown. The drawdown negatively impacted third quarter sales and will impact fourth quarter sales. In response to this changed environment, Trex Residential immediately took measures to manage a production slowdown, including labor force reductions, production optimization, as well as other cost actions.
Net Sales
. Net sales consist of sales and freight, net of discounts. The level of net sales is principally affected by sales volume and the prices paid for Trex products. Trex Residential operating results have historically varied from quarter to quarter. Seasonal, erratic or prolonged adverse weather conditions in certain geographic regions reduce the level of home and commercial improvement and residential and commercial construction and can shift demand for our products to a later period. As part of our normal business practice and consistent with industry practice, we have historically provided our distributors and dealers of our Trex Residential products incentives to build inventory levels before the start of the prime deck-building season to ensure adequate availability of our product to meet anticipated seasonal consumer demand and to enable production planning. These incentives include payment discounts, favorable payment terms, price discounts, or volume rebates on specified products and other incentives based on increases in purchases as part of specific promotional programs. The timing of our incentive programs can significantly impact sales, receivables and inventory levels during the offering period. In addition, the operating results for Trex Commercial are driven by the timing of individual projects, which may vary each quarterly period.
Gross Profit.
Gross profit represents the difference between net sales and cost of sales. Cost of sales consists of raw material costs, direct labor costs, manufacturing costs, subcontract costs and freight. Raw material costs generally include the costs to purchase and transport reclaimed wood fiber, reclaimed polyethylene, pigmentation for coloring our products, and commodities used in the production of railing and staging. Direct labor costs include wages and benefits of personnel engaged in the manufacturing process. Manufacturing costs consist of costs of depreciation, utilities, maintenance supplies and repairs, indirect labor, including wages and benefits, and warehouse and equipment rental activities.
Selling, General and Administrative Expenses.
The largest component of selling, general and administrative expenses is personnel related costs, which includes salaries, commissions, incentive compensation, and benefits of personnel engaged in sales and marketing, accounting, information technology, corporate operations, research and development, and other business functions. Another component of selling, general and administrative expenses is branding and other sales and marketing costs, which are used to build brand awareness. These costs consist primarily of advertising, merchandising, and other promotional costs. Other general and administrative expenses include professional fees, office occupancy costs attributable to the business functions previously referenced, and consumer relations expenses. As a percentage of net sales, selling, general and administrative expenses may vary from quarter to quarter due, in part, to the seasonality of our business.
Below is the discussion and analysis of our operating results and material changes in our operating results for the three months ended September 30, 2022 (2022 quarter) compared to the three months ended September 30, 2021 (2021 quarter), and for the nine months ended September 30, 2022 (2022 nine-month period) compared to the nine months ended September 30, 2021 (2021 nine-month period).

Total net sales decreased by 43.9% in the 2022 quarter compared to the 2021 quarter reflecting a 44.3% decrease in Trex Residential net sales and a 35.8% decrease in Trex Commercial net sales. The decrease in Trex Residential net sales was primarily due to a 48.2% decline in volume. Beginning in the third quarter, our channel partners looked to rightsize their inventory and meet demand partially through inventory drawdown rather than reordering products, which adversely impacted third quarter sales.

Gross profit as a percentage of net sales, gross margin, was 24.5% in the 2022 quarter compared to 38.2% in the 2021 quarter. Gross margin for Trex Residential and Trex Commercial was 25.4% and 10.2%, respectively, in the 2022 quarter compared to 38.9% and 24.0%, respectively, in the 2021 quarter. The decrease in consolidated gross margin was driven by the decrease in Trex Residential gross margin. The decrease was primarily due to reduced production resulting from our channel partners inventory drawdown to rightsize their inventories and additional costs as we rightsize our inventory with current production levels. The decrease was offset by labor force reductions, production optimization, and other actions to improve our cost position.

Selling, general and administrative expenses decreased $7.1 million in the 2022 quarter. Excluding the $1.2 million severance charge related to labor force reductions in the 2022 quarter, the decrease in selling, general and administrative expenses in the 2022 quarter was $8.3 million compared to the 2021 quarter. The $8.3 million decrease was primarily the result of a $10.2 million decrease in personnel related expenses, offset by a $1.9 million increase in marketing and branding spend, and a $1.7 million increase in other operating expenses.

EBITDA as a percentage of net sales, EBITDA margin, was 16.4% for the 2022 quarter compared to 32.2% in the 2021 quarter. The decrease in EBITDA and EBITDA margin was driven by a 70.1% decrease in Trex Residential EBITDA, primarily due to the decrease in net sales and gross margin.

1 | EBITDA represents net income before interest, income taxes, depreciation and amortization. EBITDA is not a measurement of financial performance under accounting principles generally accepted in the United States (GAAP). We have included data with respect to EBITDA and EBITDA as a percentage of net sales (EBITDA margin) because management believes it facilitates performance comparison between the Company and its competitors, and management evaluates the performance of its reportable segments using several measures, including EBITDA and EBITDA margin. Management considers EBITDA to be an important supplemental indicator of our core operating performance because it eliminates interest, income taxes, and depreciation and amortization charges to net income or loss. In relation to competitors, EBITDA and EBITDA margin eliminate differences among companies in capitalization and tax structures, capital investment cycles and ages of related assets. For these reasons, management believes that EBITDA and EBITDA margin provide important information regarding the operating performance of the Company and its reportable segments. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, the Company’s reported results prepared in accordance with GAAP and are not meant to be considered superior to or a substitute for our GAAP results.

Indebtedness On and After May
18, 2022
. On May 18, 2022, the Company, as borrower; Trex Commercial Products, Inc. (TCP), as guarantor; Bank of America, N.A. (BOA), as a Lender, Administrative Agent, Swing Line Lender and L/C Issuer; Wells Fargo Bank, National Association (Wells Fargo), as lender and Syndication Agent; Regions Bank, PNC Bank, National Association, and TD Bank, N.A. (each, a Lender and collectively, the Lenders), arranged by BofA Securities, Inc. as Sole Lead Arranger and Sole Bookrunner, entered into a Credit Agreement (Credit Agreement) to amend and restate the Fourth Amended and Restated Credit Agreement dated as of November 5, 2019.
Under the Credit Agreement, the Lenders agreed to provide the Company with one or more Revolving Loans in a collective maximum principal amount of $400,000,000 (Loan Limit) throughout the term, which ends May 18, 2027 (Term). Included within the Loan Limit are sublimits for a Letter of Credit facility in an amount not to exceed $60,000,000; and Swing Line Loans in an aggregate principal amount at any time outstanding not to exceed $20,000,000. The Revolving Loans, the Letter of Credit facility and the Swing Line Loans are for the purpose of raising working capital and supporting general business operations.
The Facility provides the Company, in the aggregate, the ability to borrow an amount up to the Loan Limit during the Term. The Company is not obligated to borrow any amount under the Loan Limit. Within the Loan Limit, the Company may borrow, repay and reborrow at any time or from time to time while the Notes are in effect. Base Rate Loans (as defined in the Credit Agreement) under the Revolving Loans and the Swing Line Loans accrue interest at the Base Rate plus the Applicable Rate (as defined in the Credit Agreement) and Term SOFR Loans for the Revolving Loans accrue interest at the rate per annum equal to the sum of Term SOFR for such interest period plus the Applicable Rate (as defined in the Credit Agreement). The Base Rate for any day is a fluctuating rate per annum equal to the highest of (a) the Federal Funds Rate plus 0.50%, (b) the rate of interest in effect for such day as publicly announced from time to time by BOA as its prime rate, and (c) the Term SOFR plus 1.0% subject to certain interest rate floors. Repayment of all then outstanding principal, interest, fees and costs is due at the end of the Term.

The Company and BofA Securities, Inc. as a sustainability coordinator, are entitled to establish specified key performance indicators (KPIs) with respect to certain environmental, social and governance targets of the Company and its subsidiaries. The sustainability coordinator and the Company may amend the Credit Agreement for the purpose of incorporating the KPIs and other related provisions, unless the Lenders object to such amendment on or prior to the date that is ten business days after the date on which such amendment is posted for review by the Lenders. Based on the performance of the Company and its subsidiaries against the KPIs, certain adjustments (increase, decrease or no adjustment) to otherwise applicable pricing will be made; provided that the amount of such adjustments shall not exceed certain aggregate caps as in the definitive loan documentation.
Under the terms of the Security and Pledge Agreement, the Company and TCP, subject to certain permitted encumbrances, as collateral security for the above-stated loans and all other present and future indebtedness of the Company owing to the Lenders grants to BOA, as Administrative Agent for the Lenders, a continuing security interest in certain collateral described and defined in the Security and Pledge Agreement but excluding the Excluded Property (as defined in the Security and Pledge Agreement).
Indebtedness Prior to May
18, 2022.
Our Fourth Amended and Restated Credit Agreement (Fourth Amended Credit Agreement) provides us with revolving loan capacity in a collective maximum principal amount of $250 million from January 1 through June 30 of each year, and a maximum principal amount of $200 million from July 1 through December 31 of each year throughout the term, which ends November 5, 2024.
On May 26, 2020, the Company entered into a First Amendment to the Original Credit Agreement (the First Amendment) to provide for an additional $100 million line of credit. As a matter of convenience, the parties incorporated the amendments to the Original Credit Agreement made by the First Amendment into a new Fourth Amended and Restated Credit Agreement (New Credit Agreement). In the New Credit Agreement, the revolving commitments under the Original Credit Agreement are referred to as Revolving A Commitments and the new $100 million line of credit is referred to as Revolving B Commitments. In the New Credit Agreement, all of the material terms and conditions related to the original line of credit (Revolving A Commitments) remained unchanged from the Original Credit Agreement.
The Company entered into the First Amendment, as borrower; Trex Commercial Products, Inc. (TCP), as guarantor; Bank of America, N.A. (BOA), as a Lender, Administrative Agent, Swing Line Lender and L/C Issuer; and certain other lenders including Wells Fargo Bank, N.A. (Wells Fargo), who is also Syndication Agent; Truist Bank (Truist); and Regions Bank (Regions) (each, a Lender and collectively, the Lenders), arranged by BofA Securities, Inc. as Sole Lead Arranger and Sole Bookrunner. The First Amendment further provides that the New Credit Agreement is amended and restated by changing Schedule 2.01 to add applicable Lender percentages related to the Revolving B Commitment for BOA of 47.5%, Well Fargo of 28.0% and Regions of 24.5%.
The Company’s revolving credit facility executed November 5, 2019 was completely replaced by the Company’s revolving credit facility executed May 18, 2022. At September 30, 2022, we had $76 million in outstanding borrowings under the revolving credit facility and borrowing capacity under the facility of $324 million.
Compliance with Debt Covenants.
Pursuant to the terms of the Credit Agreement, the Company is subject to certain loan compliance covenants. The Company was in compliance with all covenants as of September 30, 2022. Failure to comply with the financial covenants could be considered a default of repayment obligations and, among other remedies, could accelerate payment of any amounts outstanding.
We believe that cash on hand, cash from operations and borrowings expected to be available under our revolving credit facilities will provide sufficient funds to fund planned capital expenditures, make scheduled principal and interest payments, fund warranty payments, and meet other cash requirements. We currently expect to fund future capital expenditures from operations and financing activities. The actual amount and timing of future capital requirements may differ materially from our estimate depending on the demand for Trex products and new market developments and opportunities.
Capital Requirements.
In October 2021, we announced plans to add a third U.S.-based Trex Residential manufacturing facility in Little Rock, Arkansas. The new campus will sit on approximately 300 acres of land and will address increased demand for Trex Residential outdoor living products. The development approach for the new campus will be modular and calibrated to demand trends for Trex Residential outdoor living products. Construction began on the new facility in the second quarter 2022, and in July 2022, the Company entered into a design-build agreement. As previously announced, the Company anticipates spending approximately $400 million on the facility and the budget for the design-build agreement is contained within this amount. Construction for the new facility will be funded primarily through the Company’s ongoing cash generation or its line of credit.

Our capital expenditure guidance for 2022 is $170 million to $180 million. In addition to the construction of our third facility, which will be located in Arkansas, our capital allocation priorities include expenditures for internal growth opportunities, manufacturing cost reductions, upgrading equipment and support systems, and acquisitions which fit our long-term growth strategy as we continue to evaluate opportunities that would be a good strategic fit for Trex, and return of capital to shareholders
Inventory in Distribution Channels.
We sell our Trex Residential decking and railing products through a tiered distribution system. We have over 50 distributors worldwide and two national retail merchandisers to which we sell our products. The distributors in turn sell the products to dealers and retail locations who in turn sell the products to end users. Significant increases in inventory levels in the distribution channel without a corresponding change in
end-use
demand could have an adverse effect on future sales.
Product Warranty.
We warrant that our Trex Residential products will be free from material defects in workmanship and materials for warranty periods ranging from 10 years to 25 years, depending on the product and its use. If there is a breach of such warranties, we have an obligation either to replace the defective product or refund the purchase price. Depending on the product and its use, we also warrant our Trex Commercial products will be free of manufacturing defects for periods ranging from 1 year to 3 years.
We continue to receive and settle claims for decking products manufactured at our Trex Residential Nevada facility prior to 2007 that exhibit surface flaking and maintain a warranty reserve to provide for the settlement of these claims. We monitor surface flaking claims activity each quarter for indications that our estimates require revision. Typically, a majority of surface flaking claims received in a fiscal year are received during the summer outdoor season, which spans the second and third fiscal quarters.
It has been our practice to utilize actuarial techniques during the third quarter, after a significant portion of all claims has been received for the fiscal year and variances to annual claims expectations are more meaningful. Our actuarial analysis is based on currently known facts and a number of assumptions. Projecting future events such as the number of claims to be received, the number of claims that will require payment and the average cost of claims 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 flows.
The number of incoming claims received in the nine months ended September 30, 2022, was significantly lower than the number of claims received in the nine months ended September 30, 2021 and lower than our expectations for 2022. Average cost per claim experienced in the nine months ended September 30, 2022 was significantly higher than that experienced in the nine months ended September 30, 2021 and higher than our expectations for the current year. The elevated average cost per claim experienced in the nine months ended September 30, 2022, was primarily the result of the closure of three large claims, which were considered in our estimation of the surface flaking warranty reserve. We believe the reserve at September 30, 2022 is sufficient to cover future surface flaking obligations. Refer to Note 18,
Commitments and Contingencies, Product Warranty
, in the Notes to the Condensed Consolidated Financial Statements in Part I. Item 1.
Condensed Consolidated Financial Statements
of this Quarterly Report on Form
10-Q
for additional information.
We estimate that the annual number of claims received will decline over time and that the average cost per claim will increase. If the level of claims received or average cost per claim differs materially from expectations, it could result in additional increases or decreases to the warranty reserve and a decrease or increase in earnings and cash flows in future periods. We estimate that a 10% change in the expected number of remaining claims to be settled with payment or the expected cost to settle claims may result in approximately a $1.6 million change in the surface flaking warranty reserve.
The following table details surface flaking claims activity related to our warranty:

|  | Nine Months Ended September 30, |

Seasonality
. The operating results for Trex Residential have historically varied from quarter to quarter. Seasonal, erratic or prolonged adverse weather conditions in certain geographic regions reduce the level of home improvement and construction activity and can shift demand for its products to a later period. As part of its normal business practice and consistent with industry practice, Trex Residential has historically offered incentive programs to its distributors and dealers to build inventory levels before the start of the prime deck-building season in order to ensure adequate availability of its product to meet anticipated seasonal consumer demand. The seasonal effects are often offset by the positive effect of the incentive programs. The operating results for Trex Commercial have not historically varied from quarter to quarter as a result of seasonality. However, they are driven by the timing of individual projects, which may vary significantly each quarterly period.
