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.

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, 2021, was lower than the number of claims received in the nine months ended September 30, 2020 and lower than the Company’s expectations for 2021. Average cost per claim experienced in the nine months ended September 30, 2021 was higher than that experienced in the nine months ended September 30, 2020 but was consistent with the Company’s expectations for the current year. The Company believes its reserve at September 30, 2021 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 continue to increase, primarily due to inflation. 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 $1.9 million change in the surface flaking warranty reserve.

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

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.

Fire at Virginia Facility

On March 13, 2021, an electrical fire occurred at one of the Company’s manufacturing buildings in its Virginia complex. No injuries occurred from the event. The building was temporarily

off-line

while damage to the building’s electrical systems was addressed. The Company has insurance coverage for repairs, incremental direct costs to serve its customers, and losses in operating income from the loss in net sales and is currently working through the claim process with its insurance company. During the three months and nine months ended September 30, 2021, the Company received partial settlements from its insurance company of $3.7 million and $4.7 million, respectively, resulting in gains on insurance proceeds. The gains on insurance proceeds are reported as a reduction to selling, general and administrative expenses in the Condensed Consolidated Statements of Comprehensive Income.
