Commitments and Contingencies Disclosure [Abstract]
Commitments, Legal Proceedings and Contingencies, and Guarantees	Commitments, Legal Proceedings and Contingencies, and Guarantees Commitments We have commitments for leases and long-term debt that are discussed further in Note 9, Debt, and Note 10, Leases. In addition, we have purchase obligations for goods and services, capital expenditures, and raw materials entered into in the normal course of business. We are a party to a number of long-term log supply agreements. At December 31, 2021, our total obligation for log purchases under contracts with third parties was approximately $190 million based on fixed contract pricing or estimated current contractual index pricing for variable contracts. Under certain log supply agreements, we have the right to cancel or reduce our commitments in the event of a mill curtailment or shutdown. Future purchase prices under most of the variable-price agreements will be set quarterly or semiannually based on regional market prices. Our log requirements and our access to supply, as well as the cost of obtaining logs, are subject to change based on, among other things, the effect of governmental laws and regulations, our manufacturing operations not operating in the normal course of business, log availability, and the status of environmental appeals. Except for deposits required pursuant to log supply contracts, these obligations are not recorded in our consolidated financial statements until contract payment terms take effect. Legal Proceedings and Contingencies 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. Guarantees We provide guarantees, indemnifications, and assurances to others. Boise Cascade Company and its subsidiaries (Boise Cascade Building Materials Distribution, L.L.C., and Boise Cascade Wood Products, L.L.C.) act as co-borrowers under our Revolving Credit Facility and ABL Term Loan, described in Note 9, Debt. Their obligations are guaranteed by each of our remaining domestic subsidiaries. Boise Cascade has issued $400.0 million of 4.875% senior notes due in 2030. At December 31, 2021, $400.0 million of the 2030 Notes were outstanding. The 2030 Notes are guaranteed by each of Boise Cascade Company's existing and future direct or indirect domestic subsidiaries that is a guarantor or co-borrower under our Revolving Credit Facility. See Note 9, Debt, for more information. Boise Cascade issued guarantees to a limited number of trade creditors of one or more of its principal operating subsidiaries, Boise Cascade Building Materials Distribution, L.L.C., and Boise Cascade Wood Products, L.L.C., for trade credit obligations arising in the ordinary course of the business of such operating subsidiaries. These included guarantees of obligations with respect to present and future log agreements of Boise Cascade Wood Products, L.L.C. and several facility leases entered into by Boise Cascade Building Materials Distribution, L.L.C. Boise Cascade's exposure under these agreements is limited to future log purchases and the minimum lease payment requirements under the agreements. We enter into a wide range of indemnification arrangements in the ordinary course of business. At December 31, 2021, we are not aware of any material liabilities arising from these indemnifications.
