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.

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 20182019 Form 10-K and the other reports we file with the Securities and Exchange Commission (SEC).

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 20182019 Form 10-K.

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.  

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 13,12, 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 an expense.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 $46.9$40.7 million and $42.8$36.5 million, for the three months ended September 30, 2019 and 2018, respectively, and $127.3 million and $117.1 million for the nine months ended September 30, 2019 and 2018, respectively, are included in "Selling and distribution expenses" in our Consolidated Statements of Operations.Operations for the three months ended March 31, 2020 and 2019. 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.

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 September 30, 2019,March 31, 2020, and December 31, 2018,2019, we had $53.6$45.5 million and $52.1$49.4 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.

Inventories included the following (work in process is not material):

Property and equipment consisted of the following asset classes:

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).

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 September 30, 2019, receivables from two customers each accounted for approximately 13% and 14%, respectively, of total receivables. At DecemberMarch 31, 2018,2020, receivables from two customers accounted for approximately 13% and 11%, respectively,12% of total receivables. At December 31, 2019, receivables from these two customers accounted for approximately 14% and 12% of total receivables. No other customer accounted for 10% or more of total receivables.

Long-term debt consisted of the following:

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. TheOn March 13, 2020, we entered into the sixth amendment to the Amended Agreement includes ato reduce the maximum amount available for revolving loans from $370 million senior secured asset-based revolving credit facilityto $350 million (Revolving Credit Facility) and ato extend the maturity date of the Credit Agreement from May 1, 2022, to the earlier of (i) March 13, 2025 and (ii) 90 days prior to the maturity of our $350 million of 5.625%senior notes due September 1, 2024 (or the maturity date of any permitted refinancing indebtedness in respect thereof). The term loan within the Amended Agreement remains at $50.0 million term loan (ABL Term Loan) maturing on May 1, 2022.. 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 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 $37$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 September 30, 2019,March 31, 2020, was $365.4$345.4 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.

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 1.75%1.50% for loans based on LIBOR and from 0.25% to 0.75%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 September 30, 2019,March 31, 2020, and December 31, 2018,2019, we had 0 borrowings outstanding under the Revolving Credit Facility and $4.6 million of letters of credit outstanding. These letters of credit and borrowings, if any, reduce Availability under the Revolving Credit Facility by an equivalent amount.

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 2.25%2.00% for LIBOR rate loans and from 0.75% to 1.25%1.00% for base rate loans, both dependent on the amount of Average Excess Availability (as defined in the Amended Agreement). During the ninethree months ended September 30, 2019,March 31, 2020, the average interest rate on the ABL Term Loan was approximately 4.14%3.26%.

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 3.1%2.3% during the ninethree months ended September 30, 2019.March 31, 2020.

On August 29, 2016, Boise Cascade issued $350 million of 5.625% senior notes due September 1, 2024 (2024 Notes), through a private placement that was exempt from the registration requirements of the Securities Act. Interest on our 2024 Notes is payable semiannually in arrears on March 1 and September 1. The 2024 Notes are guaranteed by each of our existing and future direct or indirect domestic subsidiaries that is a guarantor under our Amended Agreement.

The 2024 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 2024 Notes.

The terms of the indenture governing the 2024 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 2024 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 2024 Notes provides for customary events of default and remedies.
