Condensed Notes to Unaudited Quarterly Consolidated Financial Statements

1.    Nature of Operations and Consolidation

Nature of Operations

    Boise Cascade Company is a building products company headquartered in Boise, Idaho. As used in this Form 10-Q, the terms "Boise Cascade," "we," and "our" refer to Boise Cascade Company and its consolidated subsidiaries. We are one of the largest producers of engineered wood products (EWP) and plywood in North America and a leading United States (U.S.) wholesale distributor of building products.

    We operate our business using two reportable segments: (1) Wood Products, which primarily manufactures EWP and plywood, and (2) Building Materials Distribution (BMD), which is a wholesale distributor of building materials. For more information, see Note 12, Segment Information.

Consolidation

    The accompanying quarterly consolidated financial statements have not been audited by an independent registered public accounting firm but, in the opinion of management, include all adjustments necessary to present fairly the financial position, results of operations, cash flows, and stockholders' equity for the interim periods presented. Except as disclosed within these condensed notes to unaudited quarterly consolidated financial statements, the adjustments made were of a normal, recurring nature. Certain information and footnote disclosures normally included in our annual consolidated financial statements have been condensed or omitted. The quarterly consolidated financial statements include the accounts of Boise Cascade and its subsidiaries after elimination of intercompany balances and transactions. Quarterly results are not necessarily indicative of results that may be expected for the full year. These condensed notes to unaudited quarterly consolidated financial statements should be read in conjunction with our 2020 Form 10-K and the other reports we file with the Securities and Exchange Commission (SEC).

2.    Summary of Significant Accounting Policies

Accounting Policies

    The complete summary of significant accounting policies is included in Note 2, Summary of Significant Accounting Policies, of the Notes to Consolidated Financial Statements in "Item 8. Financial Statements and Supplementary Data" in our 2020 Form 10-K.

Use of Estimates

    The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (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 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.  

8

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. For revenue disaggregated by major product line for each reportable segment, see Note 12, Segment Information.

    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 Building Materials Distribution segment, costs related to shipping and handling of $49.7 million and $44.2 million, for the three months ended June 30, 2021 and 2020, respectively, and $96.2 million and $84.9 million for the six months ended June 30, 2021 and 2020, respectively, are included in "Selling and distribution expenses" in our Consolidated Statements of Operations. In our Building Materials Distribution segment, our activities relate to the purchase and resale of finished product, 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.

Customer Rebates and Allowances

    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. 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 June 30, 2021, and December 31, 2020, we had $93.1 million and $56.3 million, respectively, of rebates payable to our customers recorded in "Accrued liabilities, Other" on our Consolidated Balance Sheets. We adjust our estimate of revenue at the earlier of when the probability of rebates paid changes 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.

Vendor Rebates and Allowances

We receive rebates and allowances from our vendors under a number of different programs, including vendor marketing programs. At June 30, 2021, and December 31, 2020, we had $11.6 million and $9.9 million, respectively, of vendor rebates and allowances recorded in "Receivables, Other" on our Consolidated Balance Sheets. 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.

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 Building Materials Distribution 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.

    Right-of-use (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

9

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.

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

    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 June 30, 2021, and December 31, 2020, we held $585.5 million and $371.8 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 June 30, 2021, and December 31, 2020, the book value of our fixed-rate debt for each period was $400.0 million, and the fair value was estimated to be $423.5 million and $432.0 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 London Interbank Offered Rate (LIBOR) 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. As discussed below, we also have interest rate swaps to mitigate our variable interest rate exposure, the fair value of which is measured based on Level 2 inputs.

Interest Rate Risk and Interest Rate Swaps

    We are exposed to interest rate risk arising from fluctuations in variable-rate LIBOR on our term loan and when we have loan amounts outstanding on our Revolving Credit Facility. At June 30, 2021, we had $50.0 million of variable-rate debt outstanding based on one-month LIBOR. Our objective is to limit the variability of interest payments on our debt. To meet this objective, we enter into receive-variable, pay-fixed interest rate swaps to change the variable-rate cash flow exposure to fixed-rate cash flows. 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.

    At June 30, 2021, we had two interest rate swap agreements. Under the interest rate swaps, we receive one-month LIBOR-based variable interest rate payments and make fixed interest rate payments, thereby fixing the interest rate on $50.0 million of variable rate debt exposure. Payments on one interest rate swap, entered into in 2016, with a notional principal amount of $50.0 million are due on a monthly basis at an annual fixed rate of 1.007%, and this swap expires in February 2022 (Initial Swap). During second quarter 2020, we entered into another forward interest rate swap agreement which commences on the expiration date of the Initial Swap. Payments on this interest rate swap with a notional principal amount of $50.0 million will be due on a monthly basis at an annual fixed rate of 0.39%, and this swap expires in June 2025.

The interest rate swap agreements were not designated as cash flow hedges, and as a result, all changes in the fair value are recognized in "Change in fair value of interest rate swaps" in our Consolidated Statements of Operations rather than through other comprehensive income. At June 30, 2021, we recorded a long-term asset of $0.7 million in "Other assets" on our Consolidated Balance Sheets, and we also recorded a long-term liability of $0.3 million in "Other long-term liabilities" on our Consolidated Balance Sheets, representing the fair value of the interest rate swap agreements. At December 31, 2020, we recorded a long-term liability of $0.6 million in "Other long-term liabilities" on our Consolidated Balance Sheets, representing the fair value of the interest rate swap agreements. The swaps were valued based on observable inputs for similar assets and liabilities and other observable inputs for interest rates and yield curves (Level 2 inputs).

11

Concentration of Credit Risk

We are exposed to credit risk related to customer accounts receivable. In order to manage credit risk, we consider customer concentrations and current economic trends and monitor the creditworthiness of significant customers based on ongoing credit evaluations. At June 30, 2021, receivables from two customers accounted for approximately 18% and 10% of total receivables. At December 31, 2020, receivables from these two customers accounted for approximately 13% and 12% of total receivables. No other customer accounted for 10% or more of total receivables.

New and Recently Adopted Accounting Standards

    In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope, which refines the scope of Topic 848 and clarifies some of its guidance as it related to recent rate reform activities. Our current contracts that reference LIBOR include certain debt instruments and interest rate swaps. The amendments are effective for eligible contract modifications subsequent to March 12, 2020, and through December 31, 2022. The adoption of these standards did not and are not expected to have a material effect on our financial statements, but we will assess any eligible contract modifications in the future.

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.

3.    Income Taxes

    For the three and six months ended June 30, 2021, we recorded $101.0 million and $152.5 million, respectively, of income tax expense and had an effective rate of 25.0% and 25.2%, respectively. During the three and six months ended June 30, 2021, the primary reason for the difference between the federal statutory income tax rate of 21% and the effective tax rate was the effect of state taxes. For the three and six months ended June 30, 2020, we recorded $11.3 million and $15.3 million, respectively, of income tax expense and had an effective rate of 25.2% and 25.1%, respectively. During the three and six months ended June 30, 2020, the primary reason for the difference between the federal statutory income tax rate of 21% and the effective tax rate was the effect of state taxes.

    During the six months ended June 30, 2021 and 2020, cash paid for taxes, net of refunds received, were $155.5 million and $8.9 million, respectively.

4.    Net Income Per Common Share

    Basic net income per common share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Weighted average common shares outstanding for the basic net income per common share calculation includes certain vested restricted stock units (RSUs) and performance stock units (PSUs) as there are no conditions under which those shares will not be issued. Diluted net income per common share is computed by dividing net income by the combination of the weighted average number of common shares outstanding during the period and other potentially dilutive weighted average common shares. Other potentially dilutive weighted average common shares include the dilutive effect of stock options, RSUs, and PSUs for each period using the treasury stock method. Under the treasury stock method, the exercise price of a share and the amount of compensation expense, if any, for future service that has not yet been recognized are assumed to be used to repurchase shares in the current period.

12

    The following table sets forth the computation of basic and diluted net income per common share:

	Three Months Ended June 30				Six Months Ended June 30
	2021		2020		2021		2020
	(thousands, except per-share data)
Net income	$	302,556	$	33,586	$	451,712	$	45,786
Weighted average common shares outstanding during the period (for basic calculation)	39,442		39,312		39,399		39,238
Dilutive effect of other potential common shares	246		75		234		143
Weighted average common shares and potential common shares (for diluted calculation)	39,688		39,387		39,633		39,381
Net income per common share - Basic	$	7.67	$	0.85	$	11.47	$	1.17
Net income per common share - Diluted	$	7.62	$	0.85	$	11.40	$	1.16

    The computation of the dilutive effect of other potential common shares excludes stock awards representing no shares and 0.1 million shares of common stock, respectively, in the three months ended June 30, 2021 and 2020, and 0.2 million and 0.1 million shares of common stock, respectively, in the six months ended June 30, 2021 and 2020. Under the treasury stock method, the inclusion of these stock awards would have been antidilutive.

5.    Curtailment of Manufacturing Facility

    On February 20, 2020, we decided to permanently curtail I-joist production at our Roxboro, North Carolina facility by March 31, 2020. As a result of the curtailment, we recorded $15.0 million of accelerated depreciation during first quarter 2020 to fully depreciate the curtailed I-joist assets. In addition, we recorded $1.7 million of various closure-related costs in "Loss on curtailment of facility" in our Consolidated Statements of Operations.

6.    Debt

Long-term debt consisted of the following:

	June 30, 2021		December 31, 2020
	(thousands)
Asset-based revolving credit facility due 2025	$	—	$	—
Asset-based credit facility term loan due 2025	50,000		50,000

Deferred financing costs	(5,790)		(6,208)
Long-term debt	$	444,210	$	443,792

Asset-Based Credit Facility

    On May 15, 2015, Boise Cascade and its principal operating subsidiaries, Boise Cascade Wood Products, L.L.C., and Boise Cascade Building Materials Distribution, L.L.C., as borrowers, and Boise Cascade Wood Products Holdings Corp., as guarantor, entered into an Amended and Restated Credit Agreement, as amended, (Amended Agreement) with Wells Fargo Capital Finance, LLC, as administrative agent, and the banks named therein as lenders. The Amended Agreement includes a $350 million senior secured asset-based revolving credit facility (Revolving Credit Facility) and a $50.0 million term loan (ABL Term Loan) maturing on March 13, 2025. Interest on borrowings under our Revolving Credit Facility and ABL Term Loan are payable monthly. Borrowings under the Amended Agreement are constrained by a borrowing base formula dependent upon levels of eligible receivables and inventory reduced by outstanding borrowings and letters of credit (Availability).

The Amended Agreement is secured by a first-priority security interest in substantially all of our assets, except for property and equipment. The proceeds of borrowings under the agreement are available for working capital and other general corporate purposes.

13

    The Amended Agreement contains customary nonfinancial covenants, including a negative pledge covenant and restrictions on new indebtedness, investments, distributions to equity holders, asset sales, and affiliate transactions, the scope of which are dependent on the Availability existing from time to time. The Amended Agreement also contains a requirement that we meet a 1:1 fixed-charge coverage ratio (FCCR), applicable only if Availability falls below 10% of the aggregate revolving lending commitments (or $35 million). Availability exceeded the minimum threshold amounts required for testing of the FCCR at all times since entering into the Amended Agreement, and Availability at June 30, 2021, was $345.3 million.

    The Amended Agreement permits us to pay dividends only if at the time of payment (i) no default has occurred or is continuing (or would result from such payment) under the Amended Agreement, and (ii) pro forma Excess Availability (as defined in the Amended Agreement) is equal to or exceeds 25% of the aggregate Revolver Commitments (as defined in the Amended Agreement) or (iii) (x) pro forma Excess Availability is equal to or exceeds 15% of the aggregate Revolver Commitment and (y) our fixed-charge coverage ratio is greater than or equal to 1:1 on a pro forma basis.

    Revolving Credit Facility

    Interest rates under the Revolving Credit Facility are based, at our election, on either LIBOR or a base rate, as defined in the Amended Agreement, plus a spread over the index elected that ranges from 1.25% to 1.50% for loans based on LIBOR and from 0.25% to 0.50% for loans based on the base rate. The spread is determined on the basis of a pricing grid that results in a higher spread as average quarterly Availability declines. Letters of credit are subject to a fronting fee payable to the issuing bank and a fee payable to the lenders equal to the LIBOR margin rate. In addition, we are required to pay an unused commitment fee at a rate of 0.25% per annum of the average unused portion of the lending commitments.

    At both June 30, 2021, and December 31, 2020, we had no borrowings outstanding under the Revolving Credit Facility and $4.7 million and $4.8 million, respectively, of letters of credit outstanding. These letters of credit and borrowings, if any, reduce Availability under the Revolving Credit Facility by an equivalent amount. During the six months ended June 30, 2021, the minimum and maximum borrowings under the Revolving Credit Facility were zero and $28.0 million, respectively, and the average interest rate on borrowings was approximately 1.37%.

    ABL Term Loan

    The ABL Term Loan was provided by institutions within the Farm Credit system. Borrowings under the ABL Term Loan may be repaid from time to time at the discretion of the borrowers without premium or penalty. However, any principal amount of ABL Term Loan repaid may not be subsequently re-borrowed.

    Interest rates under the ABL Term Loan are based, at our election, on either LIBOR or a base rate, as defined in the Amended Agreement, plus a spread over the index elected that ranges from 1.75% to 2.00% for LIBOR rate loans and from 0.75% to 1.00% for base rate loans, both dependent on the amount of Average Excess Availability (as defined in the Amended Agreement). During the six months ended June 30, 2021, the average interest rate on the ABL Term Loan was approximately 1.86%.

    We have received and expect to continue receiving patronage credits under the ABL Term Loan. Patronage credits are distributions of profits from banks in the Farm Credit system, which are cooperatives that are required to distribute profits to their members. Patronage distributions, which are generally made in cash, are received in the year after they are earned. Patronage credits are recorded as a reduction to interest expense in the year earned. After giving effect to expected patronage distributions, the effective average net interest rate on the ABL Term Loan was approximately 0.9% during the six months ended June 30, 2021.

14

2030 Notes

On July 27, 2020, we issued $400 million of 4.875% senior notes due July 1, 2030 (2030 Notes) through a private placement that was exempt from the registration requirements of the Securities Act. Interest on our 2030 Notes is payable semiannually in arrears on January 1 and July 1. The 2030 Notes are guaranteed by each of our existing and future direct or indirect domestic subsidiaries that is a guarantor under our Amended Agreement.

The 2030 Notes are senior unsecured obligations and rank equally with all of the existing and future senior indebtedness of Boise Cascade Company and of the guarantors, senior to all of their existing and future subordinated indebtedness, effectively subordinated to all of their present and future senior secured indebtedness (including all borrowings with respect to our Amended Agreement to the extent of the value of the assets securing such indebtedness), and structurally subordinated to the indebtedness of any subsidiaries that do not guarantee the 2030 Notes.

The terms of the indenture governing the 2030 Notes, among other things, limit the ability of Boise Cascade and our restricted subsidiaries to: incur additional debt; declare or pay dividends; redeem stock or make other distributions to stockholders; make investments; create liens on assets; consolidate, merge or transfer substantially all of their assets; enter into transactions with affiliates; and sell or transfer certain assets. The indenture governing the 2030 Notes permits us to pay dividends only if at the time of payment (i) no default has occurred or is continuing (or would result from such payment) under the indenture, and (ii) our consolidated leverage ratio is no greater than 3.5:1, or (iii) the dividend, together with other dividends since the issue date, would not exceed our "builder" basket under the indenture. In addition, the indenture includes certain specific baskets for the payment of dividends.

The indenture governing the 2030 Notes provides for customary events of default and remedies.

Interest Rate Swaps

    During the six months ended June 30, 2021, we paid $0.2 million in cash to the nonqualified pension plan participants. For the remainder of 2021, we expect to make approximately $0.2 million in cash payments to our nonqualified pension plan participants.

9.    Stock-Based Compensation

    In first quarter 2021 and 2020, we granted two types of stock-based awards under our incentive plan: performance stock units (PSUs) and restricted stock units (RSUs).

PSU and RSU Awards

    During the six months ended June 30, 2021, we granted 73,265 PSUs to our officers and other employees, subject to performance and service conditions. For the officers, the number of shares actually awarded will range from 0% and 200% of the target amount, depending upon Boise Cascade's 2021 return on invested capital (ROIC), as approved by our Compensation Committee in accordance with the related grant agreement. For the other employees, the number of shares actually awarded will range from 0% to 200% of the target amount, depending upon Boise Cascade’s 2021 EBITDA, defined as income before interest (interest expense and interest income), income taxes, and depreciation and amortization, determined in accordance with the related grant agreement. Because the ROIC and EBITDA components contain a performance condition, we record compensation expense over the requisite service period based on the most probable number of shares expected to vest.

    During the six months ended June 30, 2020, we granted 94,850 PSUs to our officers and other employees, subject to performance and service conditions. During the 2020 performance period, officers and other employees both earned 200% of the target based on Boise Cascade’s 2020 ROIC and EBITDA, determined by our Compensation Committee in accordance with the related grant agreement.

    The PSUs granted to officers generally vest in a single installment three years from the date of grant, while the PSUs granted to other employees vest in three equal tranches each year after the grant date.

    During the six months ended June 30, 2021 and 2020, we granted an aggregate of 99,588 and 125,716 RSUs, respectively, to our officers, other employees, and nonemployee directors with only service conditions. The RSUs granted to officers and other employees vest in three equal tranches each year after the grant date. The RSUs granted to nonemployee directors vest over a one year period.

    We based the fair value of PSU and RSU awards on the closing market price of our common stock on the grant date. During the six months ended June 30, 2021 and 2020, the total fair value of PSUs and RSUs vested was $9.2 million and $11.1 million, respectively.

17

    The following summarizes the activity of our PSUs and RSUs awarded under our incentive plan for the six months ended June 30, 2021:

	PSUs			RSUs
	Number of shares	Weighted Average Grant-Date Fair Value		Number of shares	Weighted Average Grant-Date Fair Value
Outstanding, December 31, 2020	196,340	$	35.34	212,766	$	34.24

_______________________________ 

(a)    Represents additional PSUs granted during the six months ended June 30, 2021, related to the 2020 performance condition adjustment described above.

Compensation Expense

    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 stock awards with only service conditions on a straight-line basis over the requisite service period. Most of our share-based compensation expense was recorded in "General and administrative expenses" in our Consolidated Statements of Operations. Total stock-based compensation recognized from PSUs and RSUs, net of forfeitures, was as follows:

	Three Months Ended June 30				Six Months Ended June 30
	2021		2020		2021		2020
	(thousands)
PSUs	$	745	$	691	$	1,834	$	1,301
RSUs	666		980		1,669		2,044
Total	$	1,411	$	1,671	$	3,503	$	3,345

    The related tax benefit for the six months ended June 30, 2021 and 2020, was $0.9 million and $0.8 million respectively. As of June 30, 2021, total unrecognized compensation expense related to nonvested share-based compensation arrangements was $14.9 million. This expense is expected to be recognized over a weighted-average period of 2.1 years.

10.    Stockholders' Equity    

Dividends

    On November 14, 2017, we announced that our board of directors approved a dividend policy to pay quarterly cash dividends to holders of our common stock. For more information regarding our dividend declarations and payments made during each of the six months ended June 30, 2021 and 2020, see "Common stock dividends" on our Consolidated Statements of Stockholders' Equity.

     On June 28, 2021, our board of directors declared a supplemental dividend of $2.00 per share on our common stock, payable on July 30, 2021, to stockholders of record on July 15, 2021. At June 30, 2021, we accrued $78.7 million in "Dividends payable" on our Consolidated Balance Sheets, representing our supplemental dividend declaration. On July 29, 2021, our board of directors declared a quarterly dividend of $0.10 per share on our common stock, payable on September 15, 2021, to stockholders of record on September 1, 2021. For a description of the restrictions in our asset-based credit facility and the indenture governing our senior notes on our ability to pay dividends, see Note 6, Debt.

18

    Future dividend declarations, including amount per share, record date and payment date, will be made at the discretion of our board of directors and will depend upon, among other things, legal capital requirements and surplus, our future operations and earnings, general financial condition, contractual obligations, restrictions imposed by our asset-based credit facility and the indenture governing our senior notes, applicable laws, and other factors that our board of directors may deem relevant.

11.    Transactions With Related Party

    Louisiana Timber Procurement Company, L.L.C. (LTP) is an unconsolidated variable-interest entity that is 50% owned by us and 50% owned by Packaging Corporation of America (PCA). LTP procures sawtimber, pulpwood, residual chips, and other residual wood fiber to meet the wood and fiber requirements of us and PCA in Louisiana. We are not the primary beneficiary of LTP as we do not have power to direct the activities that most significantly affect the economic performance of LTP. Accordingly, we do not consolidate LTP's results in our financial statements.

Background

    Boise Cascade Company is a building products company headquartered in Boise, Idaho. As used in this Form 10-Q, the terms "Boise Cascade," "we," and "our" refer to Boise Cascade Company and its consolidated subsidiaries. Boise Cascade is a large, vertically-integrated wood products manufacturer and building materials distributor. We have two reportable segments: (i) Wood Products, which primarily manufactures engineered wood products (EWP) and plywood; and (ii) Building Materials Distribution (BMD), which is a wholesale distributor of building materials. Demand for the products we manufacture, as well as the products we purchase and distribute, is closely correlated with new residential construction in the U.S. To a lesser extent, demand for our products correlates with residential repair-and-remodeling activity and light commercial construction. For more information, see Note 12, Segment Information, of the Condensed Notes to Unaudited Quarterly Consolidated Financial Statements in "Item 1. Financial Statements" of this Form 10-Q.

Executive Overview

    We recorded income from operations of $409.8 million during the three months ended June 30, 2021, compared with income from operations of $51.8 million during the three months ended June 30, 2020. In our Wood Products segment, income increased $196.7 million to $213.8 million for the three months ended June 30, 2021, from $17.1 million for the three months ended June 30, 2020, due primarily to higher plywood, EWP, and lumber sales prices, as well as higher EWP sales volumes, offset partially by higher wood fiber costs. In our Building Materials Distribution segment, income increased $163.1 million to $206.3 million for the three months ended June 30, 2021, from $43.2 million for the three months ended June 30, 2020, driven by a gross margin increase of $187.9 million, resulting primarily from improved sales volumes and gross margins on substantially all products lines, particularly commodity products, compared with second quarter 2020. The margin improvement was offset partially by increased selling and distribution expenses of $25.9 million. These changes are discussed further in "Our Operating Results" below.

    We ended second quarter 2021 with $653.8 million of cash and cash equivalents and $345.3 million of undrawn committed bank line availability, for total available liquidity of $999.1 million. We had $444.2 million of outstanding debt at June 30, 2021. We generated $248.4 million of cash during the six months ended June 30, 2021, as cash provided by operations was offset partially by capital spending, dividends paid on our common stock, and tax withholding payments on stock-based awards. A further description of our cash sources and uses for the six month comparative periods are discussed in "Liquidity and Capital Resources" below.

As both a manufacturer and a distributor, our second quarter 2021 financial results were favorably impacted by higher commodity wood products pricing compared to pricing in the same period last year, driven by continued robust construction activity during second quarter 2021. While not subject to the significant price fluctuations of commodity products, demand also exceeded supply for many of the general line and EWP products distributed by BMD. Lumber pricing peaked in May 2021, then dropped sharply driven by declining repair and remodel and "do-it-yourself" activity, causing hesitancy in the marketplace

22

because of expectations for potential price erosion. With COVID-19 vaccines and easing pandemic restrictions, people are spending less time at home on home improvement projects, resulting in reduced demand from our home center customers.

In recent months, the effects of the COVID-19 vaccine and COVID-19 safety protocols have resulted in fewer pandemic-related disruptions to both our manufacturing and distribution locations. Although many restrictions related to COVID-19 have been lightened, we continue to conduct business with certain modifications to mill and distribution center housekeeping and cleanliness protocols, employee travel, employee work locations, and virtualization or cancellation of certain sales and marketing events, among other modifications. In addition, we continue to actively monitor evolving developments, including the impact of COVID-19 variants, and may take actions that alter our business operations as may be required by federal, state, or local authorities, or that we determine are in the best interests of our employees, customers, suppliers, communities, and stockholders.

Economic uncertainty due to the pandemic continues. However, low mortgage rates, continuation of work-from-home practices by many in the economy, and demographics in the U.S. have created a favorable demand environment for new residential construction, particularly single-family housing starts, which we expect to continue in 2021 and into next year. As of July 2021, the Blue Chip Economic Indicators consensus forecast for 2021 and 2022 single- and multi-family housing starts in the U.S. were 1.60 million and 1.58 million units, respectively, compared with actual housing starts of 1.38 million in 2020, as reported by the U.S. Census Bureau. Although we believe that current U.S. demographics support the higher level of forecasted housing starts, and many national home builders are reporting strong near-term backlogs, labor shortages and supply induced constraints on residential construction activity may continue to extend build times and limit activity. In addition, while the age of the U.S. housing stock and limited home inventory availability will continue to provide a favorable backdrop for repair and remodel spending, we expect the recent decline in home improvement demand to continue near-term as travel restrictions are rescinded and pent-up demand for leisure spending occurs.

As a wholesale distributor of a broad mix of commodity products and a manufacturer of certain commodity products, we have sales and profitability exposure to declines in commodity product prices. Lumber pricing was very volatile during second quarter 2021, with rapidly rising prices in April and most of May followed by sharp price declines during the remainder of the quarter. Our BMD segment purchases and resells a broad mix of commodity products with periods of increasing prices providing the opportunity for higher sales and increased margins, while declining price environments expose us to declines in sales and profitability. Current composite panel and lumber prices have declined by approximately 53% and 48% from levels at the end of second quarter 2021. Future commodity product pricing and commodity input costs could be volatile in response to capacity restoration and industry operating rates, the impact of COVID-19 on residential construction, net import and export activity, transportation constraints or disruptions, inventory levels in various distribution channels, and seasonal demand patterns.

Factors That Affect Our Operating Results and Trends

    Our results of operations and financial performance are influenced by a variety of factors, including the following:

•the commodity nature of our products and their price movements, which are driven largely by industry capacity and operating rates, industry cycles that affect supply and demand, and net import and export activity;

•general economic conditions, including but not limited to housing starts, repair-and-remodeling activity, light commercial construction, inventory levels of new and existing homes for sale, foreclosure rates, interest rates, unemployment rates, household formation rates, prospective home buyers' access to and cost of financing, and housing affordability, that ultimately affect demand for our products;

•the duration and magnitude of impacts of the COVID-19 pandemic and related variants;

•the highly competitive nature of our industry;

•disruptions to information systems used to process and store customer, employee, and vendor information, as well as the technology that manages our operations and other business processes;

•material disruptions and/or major equipment failure at our manufacturing facilities;

•concentration of our sales among a relatively small group of customers, as well as the financial condition and creditworthiness of our customers;

23

•product shortages, loss of key suppliers, and our dependence on third-party suppliers and manufacturers;

•labor disruptions, shortages of skilled and technical labor, or increased labor costs;

•the need to successfully formulate and implement succession plans for key members of our management team;

•impairment of our long-lived assets, goodwill, and/or intangible assets;

•cost and availability of raw materials, including wood fiber and glues and resins;

•cost of compliance with government regulations, in particular environmental regulations;

•our ability to successfully and efficiently complete and integrate acquisitions;

•declines in demand for our products due to competing technologies or materials, as well as changes in building code provisions;

•substantial ongoing capital investment costs, including those associated with acquisitions, and the difficulty in offsetting fixed costs related to those investments;

•the cost and availability of third-party transportation services used to deliver the goods we manufacture and distribute, as well as our raw materials;

•exposure to product liability, product warranty, casualty, construction defect, and other claims;

•our indebtedness, including the possibility that we may not generate sufficient cash flows from operations or that future borrowings may not be available in amounts sufficient to fulfill our debt obligations and fund other liquidity needs;

•restrictive covenants contained in our debt agreements;

•fluctuations in the market for our equity; and

•the other factors described in "Item 1A. Risk Factors" in our 2020 Form 10-K.

Sales

    For the three months ended June 30, 2021, total sales increased $1,200.4 million, or 97%, to $2,443.2 million from $1,242.8 million during the three months ended June 30, 2020. For the six months ended June 30, 2021, total sales increased by $1,851.2 million, or 77%, to $4,264.5 million from $2,413.3 million for the same period in the prior year. As described below, the increase in sales was driven by the changes in sales prices and volumes for the products we manufacture and distribute with single-family residential construction activity being the key demand driver of our sales. In second quarter 2021, U.S. housing starts increased 43%, with single-family starts up 42% from the same period in 2020. On a year-to-date basis through June 2021, total and single-family housing starts increased 25% and 30%, respectively, compared with the same period in 2020. Average composite panel and average composite lumber prices for the three months ended June 30, 2021, were 280% and 210% higher, respectively, than in the same period in the prior year, as reflected by Random Lengths composite panel and lumber pricing. For the six months ended June 30, 2021, average composite panel and average composite lumber prices were 217% and 177% higher, respectively, compared with the same period in the prior year.

    Wood Products.  Sales, including sales to our BMD segment, increased $313.1 million, or 111%, to $594.6 million for the three months ended June 30, 2021, from $281.5 million for the three months ended June 30, 2020. The increase in sales was driven primarily by higher plywood prices of 206%, resulting in increased sales of $199.5 million. Plywood demand in the second quarter outpaced industry production levels, driving the favorable pricing. Higher sales volumes for I-joists and LVL of 53% and 22%, respectively, resulted in increased sales of $33.0 million and $15.7 million, respectively. In addition, sales prices for I-joists and LVL increased 8% and 7%, respectively, resulting in increased sales of $7.8 million and $5.9 million, respectively. Improved lumber sales prices and plywood sales volumes of 124% and 8%, respectively, contributed $14.0 million and $6.8 million, respectively, to the increase in sales.

For the six months ended June 30, 2021, sales, including sales to our BMD segment, increased $425.3 million, or 71%, to $1,026.9 million from $601.6 million for the same period in the prior year. The increase in sales was driven primarily by higher plywood prices of 162%, resulting in increased sales of $287.5 million. Higher sales volumes for I-joists and LVL of 35% and 6%, respectively, resulted in increased sales of $48.6 million and $10.0 million, respectively. In addition, sales prices for I-joists and LVL increased 6% and 5%, respectively, resulting in increased sales of $10.8 million and $8.0 million, respectively. Improved lumber sales prices and plywood sales volumes of 107% and 1%, respectively, contributed $22.8 million and $2.5 million, respectively, to the increase in sales.

Building Materials Distribution.  Sales increased $1,038.5 million, or 92%, to $2,172.7 million for the three months ended June 30, 2021, from $1,134.3 million for the three months ended June 30, 2020. Compared with the same quarter in the prior year, the overall increase in sales was driven by sales price and volume increases of 83% and 9%, respectively. By product line, commodity sales increased 167%, or $818.8 million; general line product sales increased 26%, or $118.5 million; and sales of EWP (substantially all of which are sourced through our Wood Products segment) increased 52%, or $101.2 million.

During the six months ended June 30, 2021, sales increased $1,623.3 million, or 74%, to $3,807.5 million from $2,184.3 million for the same period in the prior year. Compared with the same period in the prior year, the overall increase in sales was driven by sales price and volume increases of 67% and 7%, respectively. By product line, commodity sales increased 138%, or $1,285.0 million; general line product sales increased 23%, or $193.6 million; and sales of EWP increased 35%, or $144.7 million.

Costs and Expenses

    Materials, labor, and other operating expenses (excluding depreciation) increased $815.6 million, or 78%, to $1,864.5 million for the three months ended June 30, 2021, compared with $1,048.9 million during the same period in the prior year. In our Wood Products segment, materials, labor, and other operating expenses increased, due to higher sales volumes, as well as higher per-unit costs of OSB (used in the manufacture of I-joists) and logs of approximately 28% and 17%, compared with second quarter 2020. However, materials, labor, and other operating expenses as a percentage of sales (MLO rate) in our Wood Products segment decreased by 2,560 basis points, which was primarily due to higher plywood, EWP, and lumber sales prices, resulting in improved leveraging of labor costs, wood fiber costs, and other manufacturing costs. In BMD, materials, labor, and other operating expenses increased, driven by higher purchased materials costs as a result of higher sales volumes and higher commodity prices, compared with second quarter 2020. However, the BMD segment MLO rate improved 220 basis points compared with second quarter 2020 due primarily to improved sales volumes and gross margin percentages for commodity products, driven by an increasing commodity price environment during most of second quarter 2021. In addition, higher sales volumes and gross margin percentages for EWP contributed to the improved MLO rate.

27

For the six months ended June 30, 2021, materials, labor, and other operating expenses (excluding depreciation), increased $1,273.8 million or 62%, to $3,315.0 million, compared with $2,041.2 million in the same period in the prior year. In our Wood Products segment, materials, labor, and other operating expenses increased, due to higher sales volumes, as well as higher per-unit costs of OSB and logs of approximately 36% and 15%, compared with the first half of 2020. However, the MLO rate in our Wood Products segment decreased by 2,090 basis points, which was primarily due to higher plywood, EWP, and lumber sales prices, resulting in improved leveraging of labor costs, wood fiber costs, and other manufacturing costs. In BMD, the increase in materials, labor, and other operating expenses was driven by higher purchased materials costs as a result of higher sales volumes and higher commodity prices, compared with the first half of 2020. However, the BMD segment MLO rate improved 240 basis points compared with the first half of 2020 due primarily to improved sales volumes and gross margin percentages for our commodity products, driven by an increasing commodity price environment during most of the first half of 2021. In addition, higher sales volumes and gross margin percentages for EWP contributed to the improved MLO rate.

    Depreciation and amortization expenses increased $0.5 million, or 3%, to $20.4 million for the three months ended June 30, 2021, compared with $19.9 million during the same period in the prior year. For the six months ended June 30, 2021. these expenses decreased $15.3 million, or 28%, to $40.0 million, compared with $55.2 million in the same period in the prior year, due primarily to recording accelerated depreciation of $15.0 million in first quarter 2020 to fully depreciate the curtailed I-joist production assets at our Roxboro, North Carolina facility. For additional information, see Note 5, Curtailment of Manufacturing Facility, of the Condensed Notes to Unaudited Quarterly Consolidated Financial Statements in "Item 1. Financial Statements" of this Form 10-Q.

    Selling and distribution expenses increased $27.2 million, or 26%, to $130.7 million for the three months ended June 30, 2021, compared with $103.6 million during the same period in the prior year, due primarily to higher employee-related expenses of $19.7 million, most of which relates to incentive compensation. In addition, the increase in selling and distribution expenses was driven by an increase in shipping and handling costs of $2.8 million, as well increased other costs associated with higher sales volumes. For the six months ended June 30, 2021, selling and distribution expenses increased $48.6 million, or 24%, to $251.7 million, compared with $203.0 million during the same period in 2020, due primarily to higher employee-related expenses of $41.3 million, most of which relates to incentive compensation, as well as higher shipping and handling costs of $5.0 million.

    General and administrative expenses decreased $0.8 million, or 4%, to $18.0 million for the three months ended June 30, 2021, compared with $18.8 million for the same period in the prior year, due primarily to lower incentive compensation expenses driven by the departure of two officers and related forfeiture of accrued incentive compensation. For the six months ended June 30, 2021, general and administrative expenses increased $8.4 million, or 24%, to $43.3 million, compared with $34.8 million during the same period in 2020. The increase was primarily a result of higher employee-related expenses of $9.0 million, most of which relates to incentive compensation.

    For the six months ended June 30, 2020, loss on curtailment of facility was $1.7 million, representing various closure-related costs from the permanent curtailment of I-joist production at our Roxboro, North Carolina facility. For additional information, see Note 5, Curtailment of Manufacturing Facility, of the Condensed Notes to Unaudited Quarterly Consolidated Financial Statements in "Item 1. Financial Statements" of this Form 10-Q.

Income From Operations

    Income from operations increased $358.0 million to $409.8 million for the three months ended June 30, 2021, compared with $51.8 million for the three months ended June 30, 2020. Income from operations increased $537.7 million to $615.0 million for the six months ended June 30, 2021, compared with $77.3 million for the six months ended June 30, 2020.

    Wood Products.  Segment income increased $196.7 million to $213.8 million for the three months ended June 30, 2021, compared with $17.1 million for the three months ended June 30, 2020. The increase in segment income was due primarily to higher plywood, EWP, and lumber sales prices, as well as higher EWP sales volumes. These increases in segment income were offset partially by higher wood fiber costs, as well as increased selling and distribution expenses of $1.3 million.

For the six months ended June 30, 2021, segment income increased $290.0 million to $310.8 million from $20.8 million for the six months ended June 30, 2020. The increase in segment income was due primarily to higher plywood, EWP, and lumber sales prices, as well as higher EWP sales volumes. In addition, first quarter 2020 results included accelerated depreciation and amortization expense and loss on curtailment of facility of $15.0 million and $1.7 million, respectively, related to the permanent curtailment of I-joist production at our Roxboro, North Carolina facility. These increases were offset partially by higher wood fiber and other manufacturing costs. In addition, selling and distribution expenses and general and administrative expenses increased $2.3 million and $1.7 million, respectively.

28

Building Materials Distribution.  Segment income increased $163.1 million to $206.3 million for the three months ended June 30, 2021, from $43.2 million for the three months ended June 30, 2020. The increase in segment income was driven by a gross margin increase of $187.9 million, resulting from improved sales volumes and gross margins on substantially all product lines, particularly commodity products, compared with second quarter 2020. The margin improvement was offset partially by increased selling and distribution expenses of $25.9 million.

For the six months ended June 30, 2021, segment income increased $254.0 million to $326.6 million from $72.5 million for the six months ended June 30, 2020. The increase in segment income was driven by a gross margin increase of $303.2 million, resulting from improved sales volumes and gross margins on substantially all product lines, particularly commodity products, compared with the first half of 2020. This improvement was offset partially by increased selling and distribution expenses and general and administrative expenses of $46.4 million and $3.5 million, respectively.

Corporate.  Unallocated corporate expenses increased $1.8 million to $10.3 million for the three months ended June 30, 2021, from $8.5 million for the same period in the prior year. As part of our self-insured risk retention program, corporate absorbed approximately $3.4 million of estimated insurance losses resulting from a fire at our BMD Phoenix location. These losses were offset partially by lower incentive compensation driven by the departure of an officer and related forfeiture of accrued incentive compensation.

For the six months ended June 30, 2021, unallocated corporate expenses increased $6.3 million to $22.3 million from $16.0 million for the six months ended June 30, 2020. The increase was due primarily to higher incentive compensation and $3.4 million of estimated insurance losses absorbed by corporate, as discussed above.

Other    

    Change in fair value of interest rate swaps. For information related to our interest rate swaps, see the discussion under "Interest Rate Risk and Interest Rate Swaps" of Note 2, Summary of Significant Accounting Policies, of the Condensed Notes to Unaudited Quarterly Consolidated Financial Statements in "Item 1. Financial Statements" of this Form 10-Q.

Income Tax Provision

    For the three and six months ended June 30, 2021, we recorded $101.0 million and $152.5 million, respectively, of income tax expense and had an effective rate of 25.0% and 25.2%, respectively. During the three and six months ended June 30, 2021, the primary reason for the difference between the federal statutory income tax rate of 21% and the effective tax rate was the effect of state taxes. For the three and six months ended June 30, 2020, we recorded $11.3 million and $15.3 million, respectively, of income tax expense and had an effective rate of 25.2% and 25.1%, respectively. During the three and six months ended June 30, 2020, the primary reason for the difference between the federal statutory income tax rate of 21% and the effective tax rate was the effect of state taxes.

Industry Mergers and Acquisitions

On August 27, 2020, Builders FirstSource, Inc. (BFS) and BMC Stock Holdings (BMC) announced a definitive merger agreement. The merger closed in early January 2021. Prior to the merger, BFS and BMC were both customers of ours. We believe we have a good relationship with the combined company and we do not expect the transaction to have a material impact on our future results of operations. The merger resulted in the combined company accounting for 18% of total receivables as of June 30, 2021.

Liquidity and Capital Resources

    We ended second quarter 2021 with $653.8 million of cash and cash equivalents and $444.2 million of debt. At June 30, 2021, we had $999.1 million of available liquidity (cash and cash equivalents and undrawn committed bank line availability). We generated $248.4 million of cash during the six months ended June 30, 2021, as cash provided by operations was offset partially by capital spending, dividends paid on our common stock, and tax withholding payments on stock-based awards. Further descriptions of our cash sources and uses for the six month comparative periods are noted below.

We believe that our cash flows from operations, combined with our current cash levels and available borrowing capacity, will be adequate to fund debt service requirements and provide cash, as required, to support our ongoing operations, capital expenditures, lease obligations, working capital, income tax payments, and to pay cash dividends to holders of our common stock over the next 12 months. We expect to fund our seasonal and intra-month working capital requirements in the remainder of 2021 from cash on hand and, if necessary, borrowings under our revolving credit facility.

29

Sources and Uses of Cash

    We generate cash primarily from sales of our products, as well as short-term and long-term borrowings. Our primary uses of cash are for expenses related to the manufacture and distribution of building products, including inventory purchased for resale, wood fiber, labor, energy, and glues and resins. In addition to paying for ongoing operating costs, we use cash to invest in our business, service our debt, pay dividends, repurchase our common stock, and meet our contractual obligations and commercial commitments. Below is a discussion of our sources and uses of cash for operating activities, investing activities, and financing activities.

	Six Months Ended June 30
	2021		2020
	(thousands)
Net cash provided by operations	$	291,179	$	118,276
Net cash used for investment	(31,002)		(28,443)
Net cash used for financing	(11,792)		(13,634)

Operating Activities

    For the six months ended June 30, 2021, our operating activities generated $291.2 million of cash, compared with $118.3 million of cash generated in the same period in 2020. The $172.9 million increase in cash provided by operations was due primarily to an improvement in income from operations. See "Our Operating Results" in this Management's Discussion and Analysis of Financial Condition and Results of Operations for more information related to factors affecting our operating results. These increases in cash were offset partially by an increase in working capital of $203.4 million during the six months ended June 30, 2021, compared with a $0.1 million decrease for the same period in the prior year. In addition, cash paid for taxes, net of refunds received, increased $146.6 million, compared to the prior year, resulting from the significant improvement in income from operations during the first half of 2021.

    The increase in working capital during the six months ended June 30, 2021 was primarily attributable to higher receivables and inventories, offset by an increase in accounts payable and accrued liabilities. The changes in working capital during the six months ended June 30, 2020 included an increase in receivables, offset by an increase in accounts payable and accrued liabilities and lower inventories. The increases in receivables in both periods primarily reflect increased sales of approximately 69% and 47%, comparing sales for the months of June 2021 and 2020 with sales for the months of December 2020 and 2019, respectively. Inventories increased during the six months ended June 30, 2021 primarily due to the growth of inventory for the building season, as well as elevated commodity prices. During the six months ended June 30, 2020, distribution inventories decreased due to stronger than expected demand and higher inventory turns, while manufacturing inventories decreased due to reduced production levels in response to lower market demand. The increase in accounts payable and accrued liabilities provided $248.1 million of cash during the six months ended June 30, 2021, compared with $95.5 million in the same period a year ago. During both periods, seasonally higher purchasing activity and extended terms offered by major vendors to our Building Materials Distribution segment led to the increase in accounts payable. During the six months ended June 30, 2021, an increase in accrued rebates contributed to the increase in accrued liabilities. During the six months ended June 30, 2020, the increase in accounts payable was offset partially by a decrease in accrued liabilities, most notably annual employee incentive compensation payouts.

Investment Activities

    During the six months ended June 30, 2021 and 2020, we used $31.5 million and $28.8 million, respectively, of cash for purchases of property and equipment, including business improvement and quality/efficiency projects, replacement and expansion projects, and ongoing environmental compliance.

    We expect capital expenditures in 2021 to total approximately $90 million to $100 million. We expect our capital spending in 2021 will be for business improvement and quality/efficiency projects, replacement projects, and ongoing environmental compliance. Included in our capital spending range is the completion of a log utilization center project at our Florien plywood and veneer plant, a new door assembly operation in Houston, and expansion of our distribution capabilities in the Nashville market. This level of capital expenditures could increase or decrease as a result of a number of factors, including acquisitions, efforts to accelerate organic growth, exercise of lease purchase options, our financial results, future economic conditions, availability of engineering and construction resources, and timing and availability of equipment purchases.

30

Financing Activities

During the six months ended June 30, 2021, our financing activities used $11.8 million of cash, including $8.4 million for common stock dividend payments and $2.7 million of tax withholding payments on stock-based awards. During the six months ended June 30, 2021, we also borrowed $28.0 million under our revolving credit facility, which were subsequently repaid during the same period with cash on hand.

    During the six months ended June 30, 2020, our financing activities used $13.6 million of cash, including $8.6 million for common stock dividend payments and $3.3 million of tax withholding payments on stock-based awards. During the six months ended June 30, 2020, we did not borrow under our revolving credit facility.

    Future dividend declarations, including amount per share, record date and payment date, will be made at the discretion of our board of directors and will depend upon, among other things, legal capital requirements and surplus, our future operations and earnings, general financial condition, contractual obligations, restrictions imposed by our asset-based credit facility and the indenture governing our senior notes, applicable laws, and other factors that our board of directors may deem relevant.

    For more information related to our debt transactions and structure, and our dividend policy, see the discussion in Note 6, Debt, and Note 10, Stockholders' Equity, respectively, of the Condensed Notes to Unaudited Quarterly Consolidated Financial Statements in "Item 1. Financial Statements" of this Form 10-Q.

Contractual Obligations

For information about contractual obligations, see Contractual Obligations in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in our 2020 Form 10-K. As of June 30, 2021, there have been no material changes in contractual obligations outside the ordinary course of business since December 31, 2020.

Off-Balance-Sheet Activities

At June 30, 2021, and December 31, 2020, we had no material off-balance-sheet arrangements with unconsolidated entities.

Guarantees

Note 10, Debt, and Note 18, Commitments, Legal Proceedings and Contingencies, and Guarantees, of the Notes to Consolidated Financial Statements in "Item 8. Financial Statements and Supplementary Data" in our 2020 Form 10-K describe the nature of our guarantees, including the approximate terms of the guarantees, how the guarantees arose, the events or circumstances that would require us to perform under the guarantees, and the maximum potential undiscounted amounts of future payments we could be required to make. As of June 30, 2021, there have been no material changes to the guarantees disclosed in our 2020 Form 10-K.

Seasonal Influences

    We are exposed to fluctuations in quarterly sales volumes and expenses due to seasonal factors. These seasonal factors are common in the building products industry. Seasonal changes in levels of building activity affect our building products businesses, which are dependent on housing starts, repair-and-remodeling activities, and light commercial construction activities. We typically report lower sales volumes in the first and fourth quarters due to the impact of poor weather on the construction market, and we generally have higher sales volumes in the second and third quarters, reflecting an increase in construction due to more favorable weather conditions. We typically have higher working capital in the first and second quarters in preparation and response to the building season. Seasonally cold weather increases costs, especially energy consumption costs, at most of our manufacturing facilities.

31

Employees

As of July 25, 2021, we had approximately 6,130 employees. Approximately 23% of these employees work pursuant to collective bargaining agreements. As of July 25, 2021, we had ten collective bargaining agreements. Two agreements covering approximately 780 employees at our Oakdale and Florien plywood plants expired on July 15, 2021, but the terms and conditions of these agreements remain in effect pending negotiation of new agreements. We may not be able to renew these agreements or may renew them on terms that are less favorable to us than the current agreements. If any of these agreements are not renewed or extended upon their termination, we could experience a material labor disruption, strike, or significantly increased labor costs at one or more of our facilities, either in the course of negotiations of a labor agreement or otherwise. Labor disruptions or shortages could prevent us from meeting customer demands or result in increased costs, thereby reducing our sales and profitability.

Disclosures of Financial Market Risks

    In the normal course of business, we are exposed to financial risks such as changes in commodity prices, interest rates, and foreign currency exchange rates. As of June 30, 2021, there have been no material changes to financial market risks disclosed in our 2020 Form 10-K.

Environmental

    As of June 30, 2021, there have been no material changes to environmental issues disclosed in our 2020 Form 10-K. For additional information, see Environmental in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in our 2020 Form 10-K.

Critical Accounting Estimates

Critical accounting estimates are those that are most important to the portrayal of our financial condition and results. These estimates require management's most difficult, subjective, or complex judgments, often as a result of the need to estimate matters that are inherently uncertain. We review the development, selection, and disclosure of our critical accounting estimates with the Audit Committee of our board of directors. For information about critical accounting estimates, see Critical Accounting Estimates in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in our 2020 Form 10-K. At June 30, 2021, there have been no material changes to our critical accounting estimates from those disclosed in our 2020 Form 10-K.

New and Recently Adopted Accounting Standards

For information related to new and recently adopted accounting standards, see "New and Recently Adopted Accounting Standards" in Note 2, Summary of Significant Accounting Policies, of the Condensed Notes to Unaudited Quarterly Consolidated Financial Statements in "Item 1. Financial Statements" in this Form 10-Q.

ITEM 3.          QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

For information relating to quantitative and qualitative disclosures about market risk, see the discussion under "Item 7A. Quantitative and Qualitative Disclosures About Market Risk" and under the headings "Disclosures of Financial Market Risks" and "Financial Instruments" in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in our 2020 Form 10-K. As of June 30, 2021, there have been no material changes in our exposure to market risk from those disclosed in our 2020 Form 10-K.

32

ITEM 4.          CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain "disclosure controls and procedures," as defined in Rule 13a-15(e) under the Exchange Act. We have designed these controls and procedures to reasonably assure that information required to be disclosed in our reports filed or submitted under the Exchange Act, such as this Form 10-Q, is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission's rules and forms. We have also designed our disclosure controls to provide reasonable assurance that such information is accumulated and communicated to our senior management, including our chief executive officer (CEO) and our chief financial officer (CFO), as appropriate, to allow them to make timely decisions regarding our required disclosures. Based on their evaluation, our CEO and CFO have concluded that as of June 30, 2021, our disclosure controls and procedures were effective in meeting the objectives for which they were designed and were operating at a reasonable assurance level.

Changes in Internal Control Over Financial Reporting

    There were no changes in our internal control over financial reporting that occurred during the three months ended June 30, 2021, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

33

PART II—OTHER INFORMATION

ITEM 1.          LEGAL PROCEEDINGS

    We are a party to legal proceedings that arise in the ordinary course of our business, including commercial liability claims, premises claims, environmental claims, and employment-related claims, among others. As of the date of this filing, we believe it is not reasonably possible that any of the legal actions against us will, individually or in the aggregate, have a material adverse effect on our financial position, results of operations, or cash flows.

SEC regulations require us to disclose certain information about proceedings arising under federal, state or local environmental provisions if we reasonably believe that such proceedings may result in monetary sanctions above a stated threshold. Pursuant to the SEC regulations, we use a threshold of $1 million or more for purposes of determining whether disclosure of any such proceedings is required.

Nature of Operations and Consolidation (Notes)

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Nature of Operations and Consolidation

Nature of Operations and Consolidation

Nature of Operations

    Boise Cascade Company is a building products company headquartered in Boise, Idaho. As used in this Form 10-Q, the terms "Boise Cascade," "we," and "our" refer to Boise Cascade Company and its consolidated subsidiaries. We are one of the largest producers of engineered wood products (EWP) and plywood in North America and a leading United States (U.S.) wholesale distributor of building products.

    We operate our business using two reportable segments: (1) Wood Products, which primarily manufactures EWP and plywood, and (2) Building Materials Distribution (BMD), which is a wholesale distributor of building materials. For more information, see Note 12, Segment Information.

Consolidation

    The accompanying quarterly consolidated financial statements have not been audited by an independent registered public accounting firm but, in the opinion of management, include all adjustments necessary to present fairly the financial position, results of operations, cash flows, and stockholders' equity for the interim periods presented. Except as disclosed within these condensed notes to unaudited quarterly consolidated financial statements, the adjustments made were of a normal, recurring nature. Certain information and footnote disclosures normally included in our annual consolidated financial statements have been condensed or omitted. The quarterly consolidated financial statements include the accounts of Boise Cascade and its subsidiaries after elimination of intercompany balances and transactions. Quarterly results are not necessarily indicative of results that may be expected for the full year. These condensed notes to unaudited quarterly consolidated financial statements should be read in conjunction with our 2020 Form 10-K and the other reports we file with the Securities and Exchange Commission (SEC).

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Accounting Policies

    The complete summary of significant accounting policies is included in Note 2, Summary of Significant Accounting Policies, of the Notes to Consolidated Financial Statements in "Item 8. Financial Statements and Supplementary Data" in our 2020 Form 10-K.

Use of Estimates

    The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (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 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

    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. For revenue disaggregated by major product line for each reportable segment, see Note 12, Segment Information.

    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 Building Materials Distribution segment, costs related to shipping and handling of $49.7 million and $44.2 million, for the three months ended June 30, 2021 and 2020, respectively, and $96.2 million and $84.9 million for the six months ended June 30, 2021 and 2020, respectively, are included in "Selling and distribution expenses" in our Consolidated Statements of Operations. In our Building Materials Distribution segment, our activities relate to the purchase and resale of finished product, 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.

Customer Rebates and Allowances

    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. 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 June 30, 2021, and December 31, 2020, we had $93.1 million and $56.3 million, respectively, of rebates payable to our customers recorded in "Accrued liabilities, Other" on our Consolidated Balance Sheets. We adjust our estimate of revenue at the earlier of when the probability of rebates paid changes 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.

Vendor Rebates and Allowances

We receive rebates and allowances from our vendors under a number of different programs, including vendor marketing programs. At June 30, 2021, and December 31, 2020, we had $11.6 million and $9.9 million, respectively, of vendor rebates and allowances recorded in "Receivables, Other" on our Consolidated Balance Sheets. 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.

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 Building Materials Distribution 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.

    Right-of-use (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.

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

    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 June 30, 2021, and December 31, 2020, we held $585.5 million and $371.8 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 June 30, 2021, and December 31, 2020, the book value of our fixed-rate debt for each period was $400.0 million, and the fair value was estimated to be $423.5 million and $432.0 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 London Interbank Offered Rate (LIBOR) 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. As discussed below, we also have interest rate swaps to mitigate our variable interest rate exposure, the fair value of which is measured based on Level 2 inputs.

Interest Rate Risk and Interest Rate Swaps

    We are exposed to interest rate risk arising from fluctuations in variable-rate LIBOR on our term loan and when we have loan amounts outstanding on our Revolving Credit Facility. At June 30, 2021, we had $50.0 million of variable-rate debt outstanding based on one-month LIBOR. Our objective is to limit the variability of interest payments on our debt. To meet this objective, we enter into receive-variable, pay-fixed interest rate swaps to change the variable-rate cash flow exposure to fixed-rate cash flows. 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.

    At June 30, 2021, we had two interest rate swap agreements. Under the interest rate swaps, we receive one-month LIBOR-based variable interest rate payments and make fixed interest rate payments, thereby fixing the interest rate on $50.0 million of variable rate debt exposure. Payments on one interest rate swap, entered into in 2016, with a notional principal amount of $50.0 million are due on a monthly basis at an annual fixed rate of 1.007%, and this swap expires in February 2022 (Initial Swap). During second quarter 2020, we entered into another forward interest rate swap agreement which commences on the expiration date of the Initial Swap. Payments on this interest rate swap with a notional principal amount of $50.0 million will be due on a monthly basis at an annual fixed rate of 0.39%, and this swap expires in June 2025.

The interest rate swap agreements were not designated as cash flow hedges, and as a result, all changes in the fair value are recognized in "Change in fair value of interest rate swaps" in our Consolidated Statements of Operations rather than through other comprehensive income. At June 30, 2021, we recorded a long-term asset of $0.7 million in "Other assets" on our Consolidated Balance Sheets, and we also recorded a long-term liability of $0.3 million in "Other long-term liabilities" on our Consolidated Balance Sheets, representing the fair value of the interest rate swap agreements. At December 31, 2020, we recorded a long-term liability of $0.6 million in "Other long-term liabilities" on our Consolidated Balance Sheets, representing the fair value of the interest rate swap agreements. The swaps were valued based on observable inputs for similar assets and liabilities and other observable inputs for interest rates and yield curves (Level 2 inputs).

Concentration of Credit Risk

We are exposed to credit risk related to customer accounts receivable. In order to manage credit risk, we consider customer concentrations and current economic trends and monitor the creditworthiness of significant customers based on ongoing credit evaluations. At June 30, 2021, receivables from two customers accounted for approximately 18% and 10% of total receivables. At December 31, 2020, receivables from these two customers accounted for approximately 13% and 12% of total receivables. No other customer accounted for 10% or more of total receivables.

New and Recently Adopted Accounting Standards

    In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope, which refines the scope of Topic 848 and clarifies some of its guidance as it related to recent rate reform activities. Our current contracts that reference LIBOR include certain debt instruments and interest rate swaps. The amendments are effective for eligible contract modifications subsequent to March 12, 2020, and through December 31, 2022. The adoption of these standards did not and are not expected to have a material effect on our financial statements, but we will assess any eligible contract modifications in the future.

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.

Net Income Per Common Share (Notes)

Earnings Per Share [Abstract]

Net Income Per Common Share

Net Income Per Common Share

    Basic net income per common share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Weighted average common shares outstanding for the basic net income per common share calculation includes certain vested restricted stock units (RSUs) and performance stock units (PSUs) as there are no conditions under which those shares will not be issued. Diluted net income per common share is computed by dividing net income by the combination of the weighted average number of common shares outstanding during the period and other potentially dilutive weighted average common shares. Other potentially dilutive weighted average common shares include the dilutive effect of stock options, RSUs, and PSUs for each period using the treasury stock method. Under the treasury stock method, the exercise price of a share and the amount of compensation expense, if any, for future service that has not yet been recognized are assumed to be used to repurchase shares in the current period.

    The following table sets forth the computation of basic and diluted net income per common share:

	Three Months Ended June 30				Six Months Ended June 30
	2021		2020		2021		2020
	(thousands, except per-share data)
Net income	$	302,556	$	33,586	$	451,712	$	45,786
Weighted average common shares outstanding during the period (for basic calculation)	39,442		39,312		39,399		39,238
Dilutive effect of other potential common shares	246		75		234		143
Weighted average common shares and potential common shares (for diluted calculation)	39,688		39,387		39,633		39,381
Net income per common share - Basic	$	7.67	$	0.85	$	11.47	$	1.17
Net income per common share - Diluted	$	7.62	$	0.85	$	11.40	$	1.16

    The computation of the dilutive effect of other potential common shares excludes stock awards representing no shares and 0.1 million shares of common stock, respectively, in the three months ended June 30, 2021 and 2020, and 0.2 million and 0.1 million shares of common stock, respectively, in the six months ended June 30, 2021 and 2020. Under the treasury stock method, the inclusion of these stock awards would have been antidilutive.

Asset-Based Credit Facility

    On May 15, 2015, Boise Cascade and its principal operating subsidiaries, Boise Cascade Wood Products, L.L.C., and Boise Cascade Building Materials Distribution, L.L.C., as borrowers, and Boise Cascade Wood Products Holdings Corp., as guarantor, entered into an Amended and Restated Credit Agreement, as amended, (Amended Agreement) with Wells Fargo Capital Finance, LLC, as administrative agent, and the banks named therein as lenders. The Amended Agreement includes a $350 million senior secured asset-based revolving credit facility (Revolving Credit Facility) and a $50.0 million term loan (ABL Term Loan) maturing on March 13, 2025. Interest on borrowings under our Revolving Credit Facility and ABL Term Loan are payable monthly. Borrowings under the Amended Agreement are constrained by a borrowing base formula dependent upon levels of eligible receivables and inventory reduced by outstanding borrowings and letters of credit (Availability).

The Amended Agreement is secured by a first-priority security interest in substantially all of our assets, except for property and equipment. The proceeds of borrowings under the agreement are available for working capital and other general corporate purposes.

    The Amended Agreement contains customary nonfinancial covenants, including a negative pledge covenant and restrictions on new indebtedness, investments, distributions to equity holders, asset sales, and affiliate transactions, the scope of which are dependent on the Availability existing from time to time. The Amended Agreement also contains a requirement that we meet a 1:1 fixed-charge coverage ratio (FCCR), applicable only if Availability falls below 10% of the aggregate revolving lending commitments (or $35 million). Availability exceeded the minimum threshold amounts required for testing of the FCCR at all times since entering into the Amended Agreement, and Availability at June 30, 2021, was $345.3 million.

    The Amended Agreement permits us to pay dividends only if at the time of payment (i) no default has occurred or is continuing (or would result from such payment) under the Amended Agreement, and (ii) pro forma Excess Availability (as defined in the Amended Agreement) is equal to or exceeds 25% of the aggregate Revolver Commitments (as defined in the Amended Agreement) or (iii) (x) pro forma Excess Availability is equal to or exceeds 15% of the aggregate Revolver Commitment and (y) our fixed-charge coverage ratio is greater than or equal to 1:1 on a pro forma basis.

    Revolving Credit Facility

    Interest rates under the Revolving Credit Facility are based, at our election, on either LIBOR or a base rate, as defined in the Amended Agreement, plus a spread over the index elected that ranges from 1.25% to 1.50% for loans based on LIBOR and from 0.25% to 0.50% for loans based on the base rate. The spread is determined on the basis of a pricing grid that results in a higher spread as average quarterly Availability declines. Letters of credit are subject to a fronting fee payable to the issuing bank and a fee payable to the lenders equal to the LIBOR margin rate. In addition, we are required to pay an unused commitment fee at a rate of 0.25% per annum of the average unused portion of the lending commitments.

    At both June 30, 2021, and December 31, 2020, we had no borrowings outstanding under the Revolving Credit Facility and $4.7 million and $4.8 million, respectively, of letters of credit outstanding. These letters of credit and borrowings, if any, reduce Availability under the Revolving Credit Facility by an equivalent amount. During the six months ended June 30, 2021, the minimum and maximum borrowings under the Revolving Credit Facility were zero and $28.0 million, respectively, and the average interest rate on borrowings was approximately 1.37%.

    ABL Term Loan

    The ABL Term Loan was provided by institutions within the Farm Credit system. Borrowings under the ABL Term Loan may be repaid from time to time at the discretion of the borrowers without premium or penalty. However, any principal amount of ABL Term Loan repaid may not be subsequently re-borrowed.

    Interest rates under the ABL Term Loan are based, at our election, on either LIBOR or a base rate, as defined in the Amended Agreement, plus a spread over the index elected that ranges from 1.75% to 2.00% for LIBOR rate loans and from 0.75% to 1.00% for base rate loans, both dependent on the amount of Average Excess Availability (as defined in the Amended Agreement). During the six months ended June 30, 2021, the average interest rate on the ABL Term Loan was approximately 1.86%.

    We have received and expect to continue receiving patronage credits under the ABL Term Loan. Patronage credits are distributions of profits from banks in the Farm Credit system, which are cooperatives that are required to distribute profits to their members. Patronage distributions, which are generally made in cash, are received in the year after they are earned. Patronage credits are recorded as a reduction to interest expense in the year earned. After giving effect to expected patronage distributions, the effective average net interest rate on the ABL Term Loan was approximately 0.9% during the six months ended June 30, 2021.

2030 Notes

On July 27, 2020, we issued $400 million of 4.875% senior notes due July 1, 2030 (2030 Notes) through a private placement that was exempt from the registration requirements of the Securities Act. Interest on our 2030 Notes is payable semiannually in arrears on January 1 and July 1. The 2030 Notes are guaranteed by each of our existing and future direct or indirect domestic subsidiaries that is a guarantor under our Amended Agreement.

The 2030 Notes are senior unsecured obligations and rank equally with all of the existing and future senior indebtedness of Boise Cascade Company and of the guarantors, senior to all of their existing and future subordinated indebtedness, effectively subordinated to all of their present and future senior secured indebtedness (including all borrowings with respect to our Amended Agreement to the extent of the value of the assets securing such indebtedness), and structurally subordinated to the indebtedness of any subsidiaries that do not guarantee the 2030 Notes.

The terms of the indenture governing the 2030 Notes, among other things, limit the ability of Boise Cascade and our restricted subsidiaries to: incur additional debt; declare or pay dividends; redeem stock or make other distributions to stockholders; make investments; create liens on assets; consolidate, merge or transfer substantially all of their assets; enter into transactions with affiliates; and sell or transfer certain assets. The indenture governing the 2030 Notes permits us to pay dividends only if at the time of payment (i) no default has occurred or is continuing (or would result from such payment) under the indenture, and (ii) our consolidated leverage ratio is no greater than 3.5:1, or (iii) the dividend, together with other dividends since the issue date, would not exceed our "builder" basket under the indenture. In addition, the indenture includes certain specific baskets for the payment of dividends.

The indenture governing the 2030 Notes provides for customary events of default and remedies.

Share-based Payment Arrangement [Abstract]

Stock-Based Compensation

Stock-Based Compensation

    In first quarter 2021 and 2020, we granted two types of stock-based awards under our incentive plan: performance stock units (PSUs) and restricted stock units (RSUs).

PSU and RSU Awards

    During the six months ended June 30, 2021, we granted 73,265 PSUs to our officers and other employees, subject to performance and service conditions. For the officers, the number of shares actually awarded will range from 0% and 200% of the target amount, depending upon Boise Cascade's 2021 return on invested capital (ROIC), as approved by our Compensation Committee in accordance with the related grant agreement. For the other employees, the number of shares actually awarded will range from 0% to 200% of the target amount, depending upon Boise Cascade’s 2021 EBITDA, defined as income before interest (interest expense and interest income), income taxes, and depreciation and amortization, determined in accordance with the related grant agreement. Because the ROIC and EBITDA components contain a performance condition, we record compensation expense over the requisite service period based on the most probable number of shares expected to vest.

    During the six months ended June 30, 2020, we granted 94,850 PSUs to our officers and other employees, subject to performance and service conditions. During the 2020 performance period, officers and other employees both earned 200% of the target based on Boise Cascade’s 2020 ROIC and EBITDA, determined by our Compensation Committee in accordance with the related grant agreement.

    The PSUs granted to officers generally vest in a single installment three years from the date of grant, while the PSUs granted to other employees vest in three equal tranches each year after the grant date.

    During the six months ended June 30, 2021 and 2020, we granted an aggregate of 99,588 and 125,716 RSUs, respectively, to our officers, other employees, and nonemployee directors with only service conditions. The RSUs granted to officers and other employees vest in three equal tranches each year after the grant date. The RSUs granted to nonemployee directors vest over a one year period.

    We based the fair value of PSU and RSU awards on the closing market price of our common stock on the grant date. During the six months ended June 30, 2021 and 2020, the total fair value of PSUs and RSUs vested was $9.2 million and $11.1 million, respectively.

    The following summarizes the activity of our PSUs and RSUs awarded under our incentive plan for the six months ended June 30, 2021:

	PSUs			RSUs

Compensation Expense

    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 stock awards with only service conditions on a straight-line basis over the requisite service period. Most of our share-based compensation expense was recorded in "General and administrative expenses" in our Consolidated Statements of Operations. Total stock-based compensation recognized from PSUs and RSUs, net of forfeitures, was as follows:

	Three Months Ended June 30				Six Months Ended June 30
	2021		2020		2021		2020
	(thousands)
PSUs	$	745	$	691	$	1,834	$	1,301
RSUs	666		980		1,669		2,044
Total	$	1,411	$	1,671	$	3,503	$	3,345

    The related tax benefit for the six months ended June 30, 2021 and 2020, was $0.9 million and $0.8 million respectively. As of June 30, 2021, total unrecognized compensation expense related to nonvested share-based compensation arrangements was $14.9 million. This expense is expected to be recognized over a weighted-average period of 2.1 years.

Stockholders' Equity    

Dividends

    On November 14, 2017, we announced that our board of directors approved a dividend policy to pay quarterly cash dividends to holders of our common stock. For more information regarding our dividend declarations and payments made during each of the six months ended June 30, 2021 and 2020, see "Common stock dividends" on our Consolidated Statements of Stockholders' Equity.

     On June 28, 2021, our board of directors declared a supplemental dividend of $2.00 per share on our common stock, payable on July 30, 2021, to stockholders of record on July 15, 2021. At June 30, 2021, we accrued $78.7 million in "Dividends payable" on our Consolidated Balance Sheets, representing our supplemental dividend declaration. On July 29, 2021, our board of directors declared a quarterly dividend of $0.10 per share on our common stock, payable on September 15, 2021, to stockholders of record on September 1, 2021. For a description of the restrictions in our asset-based credit facility and the indenture governing our senior notes on our ability to pay dividends, see Note 6, Debt.

    Future dividend declarations, including amount per share, record date and payment date, will be made at the discretion of our board of directors and will depend upon, among other things, legal capital requirements and surplus, our future operations and earnings, general financial condition, contractual obligations, restrictions imposed by our asset-based credit facility and the indenture governing our senior notes, applicable laws, and other factors that our board of directors may deem relevant.

Transactions With Related Party

Transactions With Related Party

    Louisiana Timber Procurement Company, L.L.C. (LTP) is an unconsolidated variable-interest entity that is 50% owned by us and 50% owned by Packaging Corporation of America (PCA). LTP procures sawtimber, pulpwood, residual chips, and other residual wood fiber to meet the wood and fiber requirements of us and PCA in Louisiana. We are not the primary beneficiary of LTP as we do not have power to direct the activities that most significantly affect the economic performance of LTP. Accordingly, we do not consolidate LTP's results in our financial statements.

Sales

Related-party sales to LTP from our Wood Products segment in our Consolidated Statements of Operations were $3.4 million and $2.5 million, respectively, during the three months ended June 30, 2021 and 2020, and $6.7 million and $6.8 million, respectively, during the six months ended June 30, 2021 and 2020. These sales are recorded in "Sales" in our Consolidated Statements of Operations.

Costs and Expenses

Related-party wood fiber purchases from LTP were $20.7 million and $13.8 million, respectively, during the three months ended June 30, 2021 and 2020, and $41.0 million and $36.4 million, respectively, during the six months ended June 30, 2021 and 2020. These costs are recorded in "Materials, labor, and other operating expenses (excluding depreciation)" in our Consolidated Statements of Operations.

Summary of Significant Accounting Policies (Policies)

6 Months Ended

Jun. 30, 2021

Accounting Policies [Abstract]

Use of Estimates [Policy Text Block]

Use of Estimates    The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (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 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. For revenue disaggregated by major product line for each reportable segment, see Note 12, Segment Information.

    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 Building Materials Distribution segment, costs related to shipping and handling of $49.7 million and $44.2 million, for the three months ended June 30, 2021 and 2020, respectively, and $96.2 million and $84.9 million for the six months ended June 30, 2021 and 2020, respectively, are included in "Selling and distribution expenses" in our Consolidated Statements of Operations. In our Building Materials Distribution segment, our activities relate to the purchase and resale of finished product, 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.

Customer Rebates and Allowances

    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. 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 June 30, 2021, and December 31, 2020, we had $93.1 million and $56.3 million, respectively, of rebates payable to our customers recorded in "Accrued liabilities, Other" on our Consolidated Balance Sheets. We adjust our estimate of revenue at the earlier of when the probability of rebates paid changes 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.

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.

Lessee, 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 Building Materials Distribution 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.

    Right-of-use (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.

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 June 30, 2021, and December 31, 2020, we held $585.5 million and $371.8 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 June 30, 2021, and December 31, 2020, the book value of our fixed-rate debt for each period was $400.0 million, and the fair value was estimated to be $423.5 million and $432.0 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 London Interbank Offered Rate (LIBOR) 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. As discussed below, we also have interest rate swaps to mitigate our variable interest rate exposure, the fair value of which is measured based on Level 2 inputs.

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.

New and recently adopted accounting standards [Policy Text Block]

New and Recently Adopted Accounting Standards

    In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope, which refines the scope of Topic 848 and clarifies some of its guidance as it related to recent rate reform activities. Our current contracts that reference LIBOR include certain debt instruments and interest rate swaps. The amendments are effective for eligible contract modifications subsequent to March 12, 2020, and through December 31, 2022. The adoption of these standards did not and are not expected to have a material effect on our financial statements, but we will assess any eligible contract modifications in the future.

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.

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 stock awards with only service conditions on a straight-line basis over the requisite service period.
