BOISE CASCADE Co

The preparation of financial statements in accordance with generally accepted accounting principles (GAAP) requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Actual results could differ from these estimates. We believe that the accounting estimates discussed below represent the accounting estimates requiring the exercise of judgment where a different set of judgments could result in the greatest changes to reported results. We reviewed the development, selection, and disclosure of our critical accounting estimates with the Audit Committee of our board of directors. Our current critical accounting estimates are as follows:

EWP Rebates and Allowances

We provide EWP rebates at various stages of the supply chain (including distributors, dealers, and homebuilders) as a means to increase sales. EWP rebates are based on the volume of purchases (measured in dollars or units), among other factors such as customer loyalty, conversion, and commitment incentives, as well as temporary protection from price increases. EWP rebate estimates are based on the most likely amount to be paid and are recorded as a decrease in "Sales" as revenue is recognized. The estimate of EWP rebates is inherently difficult due to the time lag of information and it is challenging to estimate sales subject to rebate as the products transition beyond our wholesale customers and through the supply chain to homebuilders. In addition, some EWP rebate accruals are estimated based on achievement of tiered sales levels, which require management to forecast sales throughout the supply chain, using incentive terms that vary at each level. Information that we consider when estimating sales activity at dealers and homebuilders includes historical sales information, sales projections, publicly available information of housing starts by homebuilder, residential development audits, and economic forecasts of new residential construction, among other economic data. We update these forecasts on a regular basis. We adjust our estimate of revenue at the earlier of the time when the probability of EWP rebates paid changes or the time when the amounts of rebates become fixed. Because of the complexity of some of these rebates, the ultimate resolution may result in payments that are materially different from our current estimate of EWP rebates payable. At December 31, 2025 and 2024, we had $52.2 million and $63.0 million, respectively, of EWP rebates payable recorded in "Accrued liabilities, Other" on our Consolidated Balance Sheets.

Long-Lived Asset Impairment

We review the carrying value of long-lived assets for impairment when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable (triggering event). No triggering event was identified during the year ended December 31, 2025. An impairment of a long-lived asset exists when the carrying value is not recoverable through future undiscounted cash flows from operations and when the carrying value of an asset or asset group exceeds its fair value.

To the extent the carrying value of the asset or asset group exceeds future undiscounted cash flows, we would be required to estimate the fair value of the asset or asset group, and long-lived asset impairment would become a critical accounting estimate. To measure future cash flows, we are required to make assumptions about future sales volumes, future product pricing, and future expenses to be incurred. Estimates of future cash flows may change based on overall economic conditions, the cost and availability of wood fiber, environmental requirements, capital spending, and other strategic management decisions. We estimate the fair value of an asset or asset group based on quoted market prices for similar assets (the amount for which the asset(s) could be bought or sold in a current transaction with a third party) when available (Level 2 measurement) or the expected proceeds from the sale of the assets (Level 3 measurement). When quoted market prices are not available, we use a discounted cash flow model to estimate fair value (Level 3 measurement).

Future events or circumstances such as sustained negative economic impacts, declines in single-family housing starts, environmental regulations or restrictions, sustained periods of weak commodity prices, loss of key customers, capacity additions by competitors, changes in the competitive position of our products, or changes in raw materials or manufacturing costs that lead us to believe the long-lived asset will no longer provide a sufficient return on investment, could prompt decisions to invest capital differently than expected, sell facilities, or curtail operations. Any of these factors, among others, could result in non-cash impairment or accelerated depreciation charges in the future with respect to long-lived assets, which could have a material impact on our results of operations in the period in which an impairment is recognized. Due to the numerous variables associated with our judgments and assumptions relating to the valuation of assets and the effects of changes on these valuations, the timing, precision, and reliability of our estimates are subject to uncertainty. As additional information becomes known, we may change our estimates.
