Accounting Policies [Abstract] |
Principles of Consolidation [Policy Text Block] | Principles of Consolidation The consolidated financial statements include the accounts of Boise Cascade and its subsidiaries. Intercompany balances and transactions have been eliminated.
Use of Estimates [Policy Text Block] | Use of Estimates The preparation of financial statements in conformity 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. Such estimates include the valuation of accounts receivable, inventories, goodwill, intangible assets, and other long-lived assets; legal contingencies; guarantee obligations; indemnifications; assumptions used in retirement, medical, and workers' compensation benefits; assumptions used in the determination of right-of-use (ROU) assets and related lease liabilities; stock-based compensation; fair value measurements; income taxes; and vendor and customer rebates, among others. These estimates and assumptions are based on management's best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. We adjust such estimates and assumptions when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in these estimates resulting from continuing changes in the economic environment will be reflected in the consolidated financial statements in future periods.
Revenue Recognition [Policy Text Block] | Revenue Recognition Revenues are recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Wood Products Segment Our Wood Products segment manufactures EWP, consisting of laminated veneer lumber (LVL), I-joists, and laminated beams, which are structural products used in applications where extra strength and consistent quality are required, such as headers and beams. LVL is also used in the manufacture of I-joists, which are assembled by combining a vertical web of OSB with top and bottom LVL or solid wood flanges. In addition, we manufacture structural, appearance, and industrial plywood panels, and ponderosa pine lumber. Our wood products are used primarily in new residential construction, residential repair-and-remodeling markets, and light commercial construction. The majority of our wood products are sold to leading wholesalers (including our BMD segment), home improvement centers, dealers, and industrial converters. For EWP, plywood and veneer, byproducts, and other products, we transfer control and recognize a sale when we ship the product from our manufacturing facility to our customer. Control transfers when product is shipped because the customer has legal title, a present obligation to pay, and risk and rewards of ownership. The amount of consideration we receive and revenue we recognize varies with changes in rebates and cash discounts we offer to our customers. See "Rebates and Cash Discounts" below. Building Materials Distribution Segment Our BMD segment is a leading national stocking wholesale distributor of building materials. We distribute a broad line of building materials, including OSB, plywood, and lumber (collectively referred to as commodities); general line items such as siding, composite decking, doors, metal products, insulation, and roofing; and EWP. Except for EWP, we purchase most of these building materials from third-party suppliers and market them primarily to dealers, home improvement centers, and specialty distributors that then sell the products to the end customers, who are typically homebuilders, independent contractors, and homeowners engaged in residential construction projects. Substantially all of BMD's EWP is sourced from our Wood Products segment. We sell products using two primary distribution methods: warehouse sales and direct sales. Warehouse sales are distributed from our warehouses to our customers. Direct sales are shipped from the manufacturer to the customer without us taking physical possession of inventory. We report direct sales on a gross basis, that is, the amounts billed to our customers are recorded as "Sales," and inventory purchased from manufacturers are recorded as "Materials, labor, and other operating expenses (excluding depreciation)." We are the principal of direct sales because we control the inventory, as we have the ability to direct its use before it is transferred to our customers. For warehouse sales, we transfer control and recognize a sale when the customer takes physical possession of the product. Control transfers when the customer takes physical possession of the product because the customer has legal title, a present obligation to pay, and risk and rewards of ownership. For direct sales, we transfer control and recognize a sale when the product is shipped from the manufacturer to the customer. Control transfers when product is shipped because the customer has legal title, a present obligation to pay, and risk and rewards of ownership. The amount of consideration we receive and revenue we recognize varies with changes in customer rebates and cash discounts we offer to our customers. See "Rebates and Cash Discounts" below. Rebates an d Cash Discounts Rebates are provided to our customers and our customers' customers based on the volume of their purchases, among other factors such as customer loyalty, conversion, and commitment, as well as temporary protection from price increases. We provide the rebates to increase the sell-through of our products. Rebates are generally estimated based on the expected amount to be paid and recorded as a decrease in "Sales." At December 31, 2022 and 2021, we had $92.9 million and $138.1 million, respectively, of rebates payable to our customers recorded in "Accrued liabilities, Other" on our Consolidated Balance Sheets. We also estimate expected cash discounts on trade accounts receivable based on an analysis of historical experience and record cash discounts as a decrease in "Sales." We adjust our estimate of revenue at the earlier of when the probability of rebates paid and cash discounts provided ch anges or when the amounts become fixed. There have not been significant changes to our estimates of rebates, although it is reasonably possible that a change in the estimate may occur. Shipping and Handling Fees for shipping and handling charged to customers for sales transactions are included in "Sales" in our Consolidated Statements of Operations. When control over products has transferred to the customer, we have elected to recognize costs related to shipping and handling as fulfillment costs. For our Wood Products segment, costs related to shipping and handling are included in "Materials, labor, and other operating expenses (excluding depreciation)" in our Consolidated Statements of Operations. In our Wood Products segment, we view our shipping and handling costs as a cost of the manufacturing process and the movement of product to our end customers. For our BMD segment, costs related to shipping and handling of $226.1 million, $195.7 million, and $177.1 million for the years ended December 31, 2022, 2021, and 2020, respectively, are included in "Selling and distribution expenses" in our Consolidated Statements of Operations. In our BMD segment, our activities relate to the purchase and resale of finished products, and excluding shipping and handling costs from "Materials, labor, and other operating expenses (excluding depreciation)" provides us a clearer view of our operating performance and the effectiveness of our sales and purchasing functions. Other Our payment terms vary by the type of customer and the products offered. The term between invoicing and when payment is due is not significant.
Cash and Cash Equivalents [Policy Text Block] | Cash and Cash Equivalents Cash equivalents consist of short-term investments that have an original maturity of three months or less at the date of purchase. At December 31, 2022 and 2021, the majority of our cash and cash equivalents were comprised of money market funds that are broadly diversified and invested in high-quality, short-duration securities, including commercial paper, certificates of deposit, U.S. government agency securities, and similar instruments. We have significant amounts of cash and cash equivalents that are in excess of federally insured limits. Though we have not experienced any losses on our cash and cash equivalents to date and we do not anticipate incurring any losses, we cannot be assured that we will not experience losses on our cash and cash equivalents.
Trade Accounts Receivables and Allowance for Doubtful Accounts [Policy Text Block] | Trade Accounts Receivables and Allowance for Doubtful Accounts Trade accounts receivable are stated at the amount we expect to collect. Trade accounts receivable do not bear interest. We make ongoing estimates relating to the collectability of our accounts receivable and maintain a reserve for estimated losses resulting from the inability of our customers to meet their financial obligations to us. At December 31, 2022 and 2021, we had $3.3 million and $2.1 million, respectively, recorded as allowances for doubtful accounts. In determining the amount of the reserve and in order to manage credit risk, we consider our historical level of credit losses, customer concentrations, and current economic trends and monitor the creditworthiness of significant customers based on ongoing credit evaluations. Our sales are principally to customers in the building products industry located in the U.S. and Canada. A significant portion of our sales are concentrated with a relatively small number of customers. In 2022, our top ten customers represented approximately 46% of sales, with one customer accounting for approximately 12% of total sales. At December 31, 2022, receivables from two customers accounted for approximately 17% and 14% of total receivables. At December 31, 2021, receivables from these two customers accounted for approximately 20% and 12% of total receivables. No other customer accounted for 10% or more of total receivables. Adjustments to allowances are charged to income. Trade accounts receivable balances that remain outstanding after we have used reasonable collection efforts are written off through a charge to the valuation allowance and a credit to accounts receivable. Although we have not experienced material credit losses in recent years, our actual future losses from uncollectable accounts may differ materially from our current estimates. As additional information becomes known, we may change our estimates. In the event we determine that a change in the reserve is appropriate, we will record a charge to "Selling and distribution expenses" in our Consolidated Statements of Operations in the period we make such a determination.
Fair Value [Policy Text Block] | Fair Value Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy under GAAP gives the highest priority to quoted market prices (Level 1) and the lowest priority to unobservable inputs (Level 3). In general, and where applicable, we use quoted prices in active markets for identical assets or liabilities to determine fair value (Level 1). If quoted prices in active markets for identical assets or liabilities are not available to determine fair value, we use quoted prices for similar assets and liabilities or inputs that are observable either directly or indirectly (Level 2). If quoted prices for identical or similar assets are not available or are unobservable, we may use internally developed valuation models, whose inputs include bid prices, and third-party valuations utilizing underlying asset assumptions (Level 3).
Financial Instruments [Policy Text Block] | Financial Instruments Our financial instruments are cash and cash equivalents, accounts receivable, accounts payable, long-term debt, and interest rate swaps. Our cash is recorded at cost, which approximates fair value, and our cash equivalents are money market funds. As of December 31, 2022 and 2021, we held $954.4 million and $701.6 million, respectively, in money market funds that are measured at fair value on a recurring basis using Level 1 inputs. The recorded values of accounts receivable and accounts payable approximate fair values based on their short-term nature. At December 31, 2022 and 2021, the book value of our fixed-rate debt for each period was $400.0 million, and the fair value was estimated to be $348.5 million and $420.0 million, respectively. The difference between the book value and the fair value is derived from the difference between the period-end market interest rate and the stated rate of our fixed-rate, long-term debt. We estimated the fair value of our fixed-rate debt using quoted market prices of our debt in inactive markets (Level 2 inputs). The interest rate on our variable-rate debt is based on market conditions such as the Secured Overnight Financing Rate (SOFR) or a base rate. Because the interest rate on the variable-rate debt is based on current market conditions, we believe that the estimated fair value of the outstanding balance on our variable-rate debt approximates book value.
Vendor Rebates and Allowances [Policy Text Block] | Rebates and allowances received from our vendors are recognized as a reduction of "Materials, labor, and other operating expenses (excluding depreciation)" when the product is sold, unless the rebates and allowances are linked to a specific incremental cost to sell a vendor's product. Amounts received from vendors that are linked to specific selling and distribution expenses are recognized as a reduction of "Selling and distribution expenses" in the period the expense is incurred.
Foreign Currency [Policy Text Block] | Foreign Currency The functional currency for our operations outside the United States is the U.S. dollar. Nonmonetary assets and liabilities and related depreciation and amortization for these foreign operations are remeasured into U.S. dollars using historical exchange rates. Monetary assets and liabilities are remeasured into U.S. dollars using the exchange rates as of the Consolidated Balance Sheet date. Revenue and expense items are remeasured into U.S. dollars using an average exchange rate prevailing during the year.
Leases [Policy Text Block] | Leases We primarily lease land, building, and equipment under operating and finance leases. We determine if an arrangement is a lease at inception and assess lease classification as either operating or finance at lease inception or upon modification. Substantially all of our leases with initial terms greater than one year are for real estate, including distribution centers, corporate headquarters, land, and other office space. Substantially all of these lease agreements have fixed payment terms based on the passage of time and are recorded in our BMD segment. Many of our leases include fixed escalation clauses, renewal options and/or termination options that are factored into our determination of lease term and lease payments when appropriate. Renewal options generally range from one to ten years with fixed payment terms similar to those in the original lease agreements. Some lease agreements provide us with the option to purchase the leased property at market value. Our lease agreements do not contain any residual value guarantees. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of fixed lease payments over the lease term. The current portion of our operating and finance lease liabilities are recorded in "Accrued liabilities, Other" on our Consolidated Balance Sheets. We use our estimated incremental borrowing rate, which is derived from information available at the lease commencement date, in determining the present value of lease payments. In determining our incremental borrowing rates, we give consideration to publicly available interest rates for instruments with similar characteristics, including credit rating, term, and collateralization. For purposes of determining straight-line rent expense, the lease term is calculated from the date we first take possession of the facility, including any periods of free rent and any renewal option periods we are reasonably certain of exercising. Variable lease expense generally includes reimbursement of actual costs for common area maintenance, property taxes, and insurance on leased real estate and are recorded as incurred. Most of our operating lease expense is recorded in "Selling and distribution expenses" in our Consolidated Statements of Operations. In addition, we do not separate lease and non-lease components for all of our leases. Our short-term leases primarily include equipment rentals with lease terms on a month-to-month basis, which provide for our seasonal needs and flexibility in the use of equipment. Our short-term leases also include certain real estate for which either party has the right to cancel upon providing notice of 30 to 90 days. We do not recognize ROU assets or lease liabilities for short-term leases.
Income Taxes [Policy Text Block] | Income Taxes We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and respective tax bases and operating loss and tax credit carryforwards, as measured using enacted tax rates expected to be in effect in the periods where temporary differences are expected to be realized or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. We recognize deferred tax assets to the extent that we believe that these assets are more likely than not to be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If we determine that we would be unable to realize our deferred tax assets in the future, we would make an adjustment to the deferred tax asset valuation allowance, which would increase the provision for income taxes. We review and update our tax positions as necessary to add any new uncertain tax positions taken, or to remove previously identified uncertain positions that have been adequately resolved. Additionally, uncertain positions may be remeasured as warranted by changes in facts or law. Accounting for uncertain tax positions requires estimating the amount, timing and likelihood of ultimate settlement. Although we believe that these estimates are reasonable, actual results could differ from these estimates.
Inventory Valuation [Policy Text Block] | Inventory Valuation Inventories are valued at the lower of cost or net realizable value. Cost is based on the first-in, first-out (FIFO) method of inventory valuation or average cost. Wholesale distribution inventories include costs incurred in bringing inventory to its existing location. Manufactured inventories include costs for materials, labor, and factory overhead. Log inventories include costs to harvest and deliver the logs.
Property and Equipment [Policy Text Block] | Property and Equipment Property and equipment are recorded at cost. Cost includes expenditures for major improvements and replacements and the amount of interest cost associated with significant capital additions. For the years ended December 31, 2022, 2021, and 2020, an insignificant amount of interest was capitalized. We expense all repair and maintenance costs as incurred. When property and equipment are retired, sold, or otherwise disposed of, the asset's carrying amount and related accumulated depreciation are removed from the accounts and any gain or loss is included in income (loss). We use the straight-line method of depreciation.
Long-Lived Asset Impairment [Policy Text Block] | Long-Lived Asset Impairment We review long-lived assets for impairment when events or changes in circumstances indicate that the carrying amount of assets may not be recoverable (triggering event). An impairment of long-lived assets 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.
Goodwill and Intangible Assets [Policy Text Block] | Goodwill and Intangible Assets Impairment We maintain two reporting units for purposes of our goodwill impairment testing, Wood Products and BMD, which are the same as our operating segments discussed in Note 16, Segment Information. We test goodwill in each of our reporting units and intangible assets with indefinite lives for impairment annually in the fourth quarter or sooner if events or changes in circumstances indicate that the carrying value of the asset may exceed fair value. We also evaluate the remaining useful lives of our finite-lived purchased intangible assets to determine whether any adjustments to the useful lives are necessary. We completed our annual assessment of goodwill in fourth quarter 2022 using a qualitative approach. The qualitative goodwill impairment assessment requires evaluating factors, based on the weight of evidence, to determine whether a reporting unit's carrying value would more likely than not exceed its fair value. As part of our goodwill qualitative testing process for each reporting unit, we evaluate various factors that are specific to the reporting unit as well as industry and macroeconomic factors in order to determine whether they are reasonably likely to have a material impact on the fair value of our reporting units. Based on the qualitative analysis performed in 2022, we concluded that there were no changes that were reasonably likely to cause the fair value of the reporting units to be less than the reporting units' carrying value and determined that there was no impairment of our goodwill. In the event we were to determine that a reporting unit's carrying value would more likely than not exceed its fair value, quantitative testing would be performed comparing carrying values to estimated fair values.
Asset Retirement Obligations [Policy Text Block] | Asset Retirement Obligations We recognize our asset retirement obligations in the period in which they are incurred if sufficient information is available to reasonably estimate the fair value of the obligation. Fair value estimates are determined using Level 3 inputs in the fair value hierarchy. The fair values of our asset retirement obligations are measured using expected future cash outflows discounted using the company's credit-adjusted risk-free interest rate. When we record the liability, we capitalize the cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its settlement value, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, we will recognize a gain or loss for any difference between the settlement amount and the liability recorded.
Deferred Software Costs [Policy Text Block] | Deferred Software Costs We defer internal-use software costs that benefit future years. These costs are amortized using the straight-line method over the expected life of the software, typically three to five years.
Self-Insurance [Policy Text Block] | Self-Insurance We are self-insured for certain losses related to workers' compensation and medical claims, general and auto liability, as well as property and business interruption losses. The expected ultimate costs for claims incurred are recognized as liabilities in the Consolidated Balance Sheets and are estimated based principally on an analysis of historical claims data and estimates of claims incurred but not reported. Losses are accrued and charged to operations when it is probable that a loss has been incurred and the amount can be reasonably estimated. We maintain third-party stop-loss insurance policies to cover these liability costs in excess of predetermined retained amounts. Costs related to the administration of the plans and related claims are expensed as incurred.
New and Recently Adopted Accounting Standards [Policy Text Block] | New and Recently Adopted Accounting Standards In October 2021, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which is intended to improve the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to recognition of an acquired contract liability and payment terms and their effect on subsequent revenue recognized by the acquirer. This ASU requires an acquirer to account for revenue contracts in accordance with Topic 606 as if it had originated the contracts. To achieve this, an acquirer may assess how the acquiree applied Topic 606 to determine what to record for the acquired revenue contracts. The updated guidance is effective for interim and annual reporting periods beginning after December 15, 2022. We adopted this standard in first quarter 2023, and it did not have a material effect on our financial statements. There were no other accounting standards recently issued that had or are expected to have a material impact on our consolidated financial statements and associated disclosures.
Revenue , transaction price measurement, tax exclusion [Policy Text Block] | Sales, value add, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue.
Commissions Expense, Policy [Policy Text Block] | We expense sales commissions when incurred as they are earned. These costs are recorded within "Selling and distribution expenses."
Business Combinations [Policy Text Block] | We account for acquisition transactions in accordance with ASC 805, Business Combinations. Accordingly, the results of operations of the acquiree are included in our consolidated financial statements from the acquisition date. The consideration transferred is allocated to the identifiable assets acquired and liabilities assumed based on estimated fair values at the acquisition date, with any excess recorded as goodwill. Transaction-related costs are expensed in the period the costs are incurred. During the measurement period, which may be up to one year from the acquisition date, we may record adjustments to the assets acquired and liabilities assumed with the corresponding adjustment to goodwill.
Compensation Related Costs [Policy Text Block] | We record compensation expense over the awards' vesting period and account for share-based award forfeitures as they occur, rather than making estimates of future forfeitures. Any shares not vested are forfeited. We recognize compensation expense for stock awards with only service conditions on a straight-line basis over the requisite service period.
Derivatives [Policy Text Block] | In accordance with our risk management strategy, we actively monitor our interest rate exposure and use derivative instruments from time to time to manage the related risk. We do not speculate using derivative instruments.
Segment Reporting [Policy Text Block] | We measure and evaluate our reportable segments based on net sales and segment operating income (loss). Accordingly, our chief operating decision maker reviews the performance of the company and allocates resources based primarily on net sales and segment operating income (loss) for our business segments. Unallocated corporate costs are presented as reconciling items to arrive at operating income. Unallocated corporate costs include corporate support staff services, related assets and liabilities, and nonqualified pension plan activity. Support services include, but are not limited to, information technology, human resources, finance, accounting, and legal functions. Specified expenses are allocated to the segments. For many of these allocated expenses, the related assets and liabilities remain in corporate.
