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 and 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.

In the six months ended June 30, 2023, the Company had a reduction in inventory that it does not expect will be replenished by year end. However, the Company estimates that the LIFO liquidation will not have a material impact on cost of sales for the year ended December 31, 2023 and, accordingly, it did not impact the cost of sales for the six months ended June 30, 2023.
