Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations and Basis of Presentation	Nature of Operations and Basis of Presentation
	We are a building products company headquartered in Boise, Idaho. Our operations began on October 29, 2004 (inception), when we acquired the forest products assets of OfficeMax (the Forest Products Acquisition). As used in these consolidated financial statements, the terms "Boise Cascade," "we," and "our" refer to Boise Cascade, L.L.C., and its consolidated subsidiaries prior to our conversion to a Delaware corporation and to Boise Cascade Company and its consolidated subsidiaries on or after such conversion. On February 4, 2013, we converted to a Delaware corporation from a Delaware limited liability company by filing a certificate of conversion in Delaware. The common stock authorized and outstanding, par values, net income per share amounts, and other per-share disclosures for all periods presented have been adjusted to reflect the impact of this conversion. We completed an initial public offering of our common stock on February 11, 2013. We are one of the largest producers of plywood and engineered wood products (EWP) in North America and a leading U.S. wholesale distributor of building products.
	We operate our business using three reportable segments: (1) Wood Products, which manufactures plywood, EWP, studs, particleboard, and ponderosa pine lumber, (2) Building Materials Distribution, which is a wholesale distributor of building materials, and (3) Corporate and Other, which includes corporate support staff services, related assets and liabilities, and foreign currency exchange gains and losses. For more information, see Note 15, Segment Information.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies
	Principles of Consolidation
	The consolidated financial statements include the accounts of Boise Cascade and its subsidiaries. Intercompany balances and transactions have been eliminated.
	Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 benefits; stock-based compensation; 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
	We recognize revenue when the following criteria are met: persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, our price to the buyer is fixed or determinable, and collectibility is reasonably assured. Delivery is not considered to have occurred until the customer takes title and assumes the risks and rewards of ownership. The timing of revenue recognition is dependent on shipping terms. Revenue is recorded at the time of shipment for terms designated free on board (fob) shipping point. For sales transactions designated fob destination, revenue is recorded when the product is delivered to the customer's delivery site.
	Fees for shipping and handling charged to customers for sales transactions are included in "Sales." For our Wood Products segment, costs related to shipping and handling are included in "Materials, labor, and other operating expenses (excluding depreciation)." 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 $104.8 million, $94.8 million, and $89.3 million are included primarily in "Selling and distribution expenses" for the years ended December 31, 2014, 2013, and 2012, respectively. 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. We present sales taxes collected from customers and remitted to governmental authorities on a net basis in our Consolidated Statements of Operations.
	Cash and Cash Equivalents
	Cash equivalents consist of short-term investments that have a maturity of three months or less at the date of purchase. At December 31, 2014 and 2013, the majority of our cash and cash equivalents were invested in money market funds that are broadly diversified and invested in high-quality, short-duration securities, including commercial paper, certificates of deposit, U.S. government agency securities, and similar instruments. We have significant amounts of cash and cash equivalents that are in excess of federally insured limits. Though we have not experienced any losses on our cash and cash equivalents to date and we do not anticipate incurring any losses, we cannot be assured that we will not experience losses on our cash and cash equivalents.
	Trade Accounts Receivables and Allowance for Doubtful Accounts
	Trade accounts receivable are stated at the amount we expect to collect. Trade accounts receivable do not bear interest. We make ongoing estimates relating to the collectibility of our accounts receivable and maintain a reserve for estimated losses resulting from the inability of our customers to meet their financial obligations to us. At December 31, 2014 and 2013, we had $2.1 million and $2.5 million, respectively, recorded as allowances for doubtful accounts. In determining the amount of the reserve and in order to manage credit risk, we consider our historical level of credit losses, customer concentrations, and current economic trends and monitor the creditworthiness of significant customers based on ongoing credit evaluations. Our sales are principally to customers in the building products industry located in the United States and Canada. A significant portion of our sales are concentrated with a relatively small number of customers. In 2014, our top ten customers represented approximately 28% of sales. At December 31, 2014 and 2013, receivables from a single customer accounted for approximately 11% and 13%, respectively, of total receivables. No other customer accounted for 10% or more of total receivables. Adjustments to the valuation allowance are charged to income. Trade accounts receivable balances that remain outstanding after we have used reasonable collection efforts are written off through a charge to the valuation allowance and a credit to accounts receivable. Although we have not experienced material credit losses in recent years, our actual future losses from uncollectible accounts may differ materially from our current estimates. As additional information becomes known, we may change our estimates. In the event we determine that a change in the reserve is appropriate, we will record a charge to "Selling and distribution expenses" in our Consolidated Statements of Operations in the period we make such a determination.
	Fair Value
	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 U.S. generally accepted accounting principles (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). See Note 7, Retirement and Benefit Plans, for the fair value measurements of our defined benefit plans' assets.
	Financial Instruments
	Our financial instruments are cash and cash equivalents, accounts receivable, accounts payable, and long-term debt. Our cash is recorded at cost, which approximates fair value, and our cash equivalents are money market funds measured at fair value. As of December 31, 2014 and 2013, we held $137.6 million and $85.8 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 December 31, 2014, the book value of our fixed-rate debt was $300.0 million, and the fair value was estimated to be $315.0 million. 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 based on quoted market prices for similar traded debt (Level 2 measurement).
	We are exposed to financial risks such as changes in interest rates, foreign currency exchange rates, and commodity price risk. We employ a variety of practices to manage these risks, including operating and financing activities and, where deemed appropriate, the use of derivative instruments. During the years ended December 31, 2014 and 2013, we had no derivative instruments.
	Vendor and Customer Rebates and Allowances
	We receive rebates and allowances from our vendors under a number of different programs, including vendor marketing programs. At December 31, 2014 and 2013, we had $6.1 million and $4.7 million, respectively, of vendor rebates and allowances recorded in "Receivables, Other" on the 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.
	We also provide rebates to our customers and our customers' customers based on the volume of their purchases. We provide the rebates to increase the sell-through of our products. The rebates are recorded as a decrease in "Sales." At December 31, 2014 and 2013, we had $24.7 million and $24.2 million, respectively, of rebates payable to our customers recorded in "Accrued liabilities, Other" on our Consolidated Balance Sheets.
	Foreign Currency
	The functional currency for our operations outside the United States is the U.S. dollar. Nonmonetary assets and liabilities and related depreciation and amortization for these foreign operations are remeasured into U.S. dollars using historical exchange rates. Monetary assets and liabilities are remeasured into U.S. dollars using the exchange rates as of the Consolidated Balance Sheet date. Revenue and expense items are remeasured into U.S. dollars using an average exchange rate prevailing during the year.
	Leases
	We assess lease classification as either capital or operating at lease inception or upon modification. We lease a portion of our distribution centers as well as other property and equipment under operating leases. Substantially all lease agreements have fixed payment terms based on the passage of time. Some lease agreements provide us with the option to purchase the leased property. Additionally, some agreements contain renewal options generally ranging from one to ten years, with fixed payment terms similar to those in the original lease agreements. 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 assured of exercising.
	Inventory Valuation
	Inventories are valued at the lower of cost or market. Cost is based on the first-in, first-out (FIFO) method of inventory valuation or average cost. Manufactured inventories include costs for materials, labor, and factory overhead. Log inventories include costs to harvest and deliver the timber.
	Inventories include the following (work in process is not material):
		December 31,			December 31,
		2014			2013
		(thousands)
	Finished goods and work in process	$	308,359		$	292,218
	Logs	57,065			65,423
	Other raw materials and supplies	29,037			25,718
		$	394,461		$	383,359
	Property and Equipment
	Property and equipment are recorded at cost. Cost includes expenditures for major improvements and replacements and the amount of interest cost associated with significant capital additions. For the years ended December 31, 2014, 2013, and 2012, we did not capitalize any interest. We expense all repair and maintenance costs as incurred. When property and equipment are retired, sold, or otherwise disposed of, the asset's carrying amount and related accumulated depreciation are removed from the accounts and any gain or loss is included in income (loss). We use the straight-line method of depreciation.
	Property and equipment consisted of the following asset classes with the following general range of estimated useful lives:
		December 31,			December 31,			General Range of Estimated Useful Lives in Years
		2014			2013
		(thousands)
	Land	$	36,819		$	37,345
	Buildings	96,804			91,594			20	-	40
	Improvements	42,699			41,372			10	-	15
	Office equipment and vehicles	93,620			80,340			3	-	7
	Machinery and equipment	410,633			380,456			7	-	12
	Construction in progress	11,118			10,063
		691,693			641,170
	Less accumulated depreciation	(323,565		)	(280,185		)
		$	368,128		$	360,985
	During 2013, we acquired $85.0 million of property and equipment through the acquisition of two plywood manufacturing facilities.
	Long-Lived Asset Impairment
	We review long-lived assets for impairment when events or changes in circumstances indicate that the carrying amount of assets may not be recoverable. An impairment of long-lived assets exists when the carrying value is not recoverable through future undiscounted cash flows from operations and when the carrying value of an asset or asset group exceeds its fair value.
	Goodwill and Intangible Assets
	We maintain two reporting units for purposes of our goodwill impairment testing, Wood Products and Building Materials Distribution, which are the same as our operating segments discussed in Note 15, Segment Information. We test goodwill in each of our reporting units and intangible assets with indefinite lives for impairment annually in the fourth quarter or sooner if events or changes in circumstances indicate that the carrying value of the asset may exceed fair value. We also evaluate the remaining useful lives of our finite-lived purchased intangible assets to determine whether any adjustments to the useful lives are necessary.
	We completed our annual assessment of goodwill in fourth quarter 2014 using a qualitative approach. The qualitative goodwill impairment assessment requires evaluating factors, based on the weight of evidence, to determine whether a reporting unit's carrying value would more likely than not exceed its fair value. As part of our goodwill qualitative testing process for each reporting unit, we evaluate various factors that are specific to the reporting unit as well as industry and macroeconomic factors in order to determine whether it is reasonably likely to have a material impact on the fair value of our reporting units. Examples of the factors that were considered include the results of the most recent quantitative impairment test, current and long-term forecasted financial results, changes in the discount rate between current and prior years, and operating strategy for each reporting unit. Based on the qualitative analysis performed in 2014, we concluded that there were no changes that were reasonably likely to cause the fair value of the reporting units to be less than the reporting units' carrying value and determined that there was no impairment of our goodwill. In the event we were to determine that a reporting unit's carrying value would more likely than not exceed its fair value, quantitative testing would be performed comparing carrying values to estimated fair values.
	For our intangible asset impairment testing, we use a discounted cash flow approach, based on a relief from royalty method (Level 3 measurement). This method assumes that, through ownership of trademarks and trade names, we avoid royalty expenses associated with licensing, resulting in cost savings. An estimated royalty rate, determined as a percentage of the related net sales, is used to estimate the value of the intangible assets. Based on the impairment tests of our intangible assets with indefinite lives performed in fourth quarter 2014, we determined that the fair value of our intangible assets exceeds their carrying value.
	See Note 11, Goodwill and Intangible Assets, for additional information.
	Asset Retirement Obligations
	We recognize our asset retirement obligations in the period in which they are incurred if sufficient information is available to reasonably estimate the fair value of the obligation. Fair value estimates are determined using Level 3 inputs in the fair value hierarchy. The fair values of our asset retirement obligations are measured using expected future cash outflows discounted using the company's credit-adjusted risk-free interest rate. When we record the liability, we capitalize the cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its settlement value, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, we will recognize a gain or loss for any difference between the settlement amount and the liability recorded.
	At December 31, 2014 and 2013, we had $0.2 million and $0.4 million, respectively, of asset retirement obligations recorded in "Other long-term liabilities" on our Consolidated Balance Sheets. At December 31, 2014, these liabilities related primarily to landfill closure costs. The liabilities are based on the best estimate of current costs and are updated periodically to reflect current technology, laws and regulations, inflation, and other economic factors. We do not have any assets legally restricted for purposes of settling asset retirement obligations.
	We have additional asset retirement obligations with indeterminate settlement dates. The fair value of these asset retirement obligations cannot be estimated due to the lack of sufficient information to estimate the settlement dates of the obligations. These asset retirement obligations include, for example, (i) removal and disposal of potentially hazardous materials on equipment and/or an operating facility if the equipment and/or facility were to undergo major maintenance, renovation, or demolition; (ii) retention ponds that may be required to be drained and/or cleaned if the related operating facility is closed; and (iii) storage sites or owned facilities for which removal and/or disposal of chemicals and other related materials are required if the operating facility is closed. We will recognize a liability in the period in which sufficient information becomes available to reasonably estimate the fair value of these obligations.
	Pension Benefits
	Several estimates and assumptions are required to record pension costs and liabilities, including discount rates, expected return on plan assets, expected rate of compensation increases, retirement and mortality rates, expected contributions, and other factors. We review and update these assumptions annually unless a plan curtailment or other event occurs requiring that we update the estimates on an interim basis. See Note 7, Retirement and Benefit Plans, for additional information related to our pension plan. While we believe that the assumptions used to measure our pension obligations are reasonable, differences in actual experience or changes in assumptions may materially affect our pension obligations and future expense.
	Long-Term Incentive Cash Plan
In 2012, key managers participated in a long-term incentive plan (LTIP) that pays awards in cash. The LTIP provided an annual award notice to participants granting them the opportunity to earn a cash award that was based on a target percentage of the participant's base salary and the company's achievement against corporate goals, both of which were set annually. Under the LTIP, the award, if any, is paid in three equal installments due no later than March 15 of the three years following the year the award was granted with continued employment as a precondition for receipt of each award installment. We recognize compensation expense based on the probability of the performance goals being met over the vesting period. We recognized $6.7 million of LTIP expense in 2012.
Deferred Software Costs
We defer internal-use software costs that benefit future years. These costs are amortized using the straight-line method over the expected life of the software, typically three to five years. "Other assets" in the Consolidated Balance Sheets includes $4.4 million and $3.7 million, respectively, of deferred software costs at December 31, 2014 and 2013. We amortized $1.3 million of deferred software costs for each of the years ended December 31, 2014 and 2013, and $1.2 million for the year ended December 31, 2012.
Labor Concentration and Unions
As of December 31, 2014, we had approximately 5,650 employees. Approximately 26% of these employees work pursuant to collective bargaining agreements. As of December 31, 2014, we had nine collective bargaining agreements. None of our employees are working pursuant to a collective bargaining agreement that will expire within the next 12 months.
Self-Insurance
We are self-insured for certain losses related to workers' compensation and medical claims as well as general and auto liability. The expected ultimate costs for claims incurred are recognized as liabilities in the Consolidated Balance Sheets and are estimated based principally on an analysis of historical claims data and estimates of claims incurred but not reported. Losses are accrued and charged to operations when it is probable that a loss has been incurred and the amount can be reasonably estimated. We maintain third-party stop-loss insurance policies to cover these liability costs in excess of predetermined retained amounts. Costs related to the administration of the plans and related claims are expensed as incurred. At December 31, 2014 and 2013, self-insurance related liabilities of $7.8 million and $7.9 million were classified within "Accrued liabilities," and $10.7 million and $10.1 million were classified within "Other long-term liabilities" on our Consolidated Balance Sheets, respectively.
New and Recently Adopted Accounting Standards
In June 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-12, Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. This ASU requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. We adopted the provisions of this guidance on January 1, 2015, and it had no effect on our financial statements.
In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. This ASU requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for annual and interim reporting periods beginning after December 15, 2016. Early adoption is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that this guidance will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our financial statements.
There were no other accounting standards recently issued that had or are expected to have a material impact on our consolidated financial statements and associated disclosures.

Income Taxes	Income Taxes
	Income Tax Provision
	As a corporation, we are subject to typical corporate U.S. federal, state, and foreign income tax rates. The effective tax rate differed from the U.S. federal statutory income tax rate principally due to the following (dollars in thousands):
			Year Ended December 31

	Income tax provision (benefit)		$	43,296		$	(38,788	)
	During the years ended December 31, 2014, 2013, and 2012, cash paid for taxes, net of refunds received, was $40.3 million, $22.7 million, and $0.2 million, respectively.
	On February 4, 2013, we converted from a limited liability company to a corporation. In addition, we elected to be treated as a corporation for federal and state income tax purposes effective as of January 1, 2013. Therefore, we are subject to federal and state income tax expense beginning January 1, 2013. For tax purposes, our conversion from a limited liability company to a corporation was deemed a nontaxable transfer of Boise Cascade, L.L.C., assets and liabilities to Boise Cascade Company. As a result of our conversion to a corporation in February 2013, we recorded net deferred tax assets of $68.7 million, the effect of which was recorded as an income tax benefit in our Consolidated Statement of Operations for the year ended December 31, 2013.
	As a limited liability company, we were treated as a disregarded entity for federal income tax purposes and, as such, were included in the income tax return for Boise Cascade Holdings, L.L.C. (BC Holdings), former parent of Boise Cascade. Our income tax provision generally consisted of income taxes payable to state jurisdictions that do not allow for the income tax liability to be passed through to our former sole member as well as income taxes payable by our separate subsidiaries that are taxed as corporations. As a limited liability company, we had an effective tax rate of less than 1%. For the year ended December 31, 2012, income tax expense was $0.3 million.
	Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts for income tax purposes. The components of our net deferred tax assets and liabilities at December 31, 2014 and 2013, are as follows (dollars in thousands):
			31-Dec-14			31-Dec-13
	Deferred tax assets
	Employee benefits (a)		$	81,414		$	55,331
	Deferred financing costs		455			540

	Deferred tax liabilities		$	55,421		$	45,806
	As reported on our Consolidated Balance Sheets
	Current deferred tax assets, net		$	20,311		$	18,151
	Noncurrent deferred tax assets, net		16,684			760
	Total deferred tax assets, net		$	36,995		$	18,911
	___________________________________
	(a)	As of December 31, 2014, the increase relates to the tax effect of changes in recorded pension liabilities. See Note 7, Retirement and Benefit Plans, for more information.
	(b)	We have an investment in foreign subsidiaries, which at December 31, 2014 and 2013, had $15.8 million and $17.2 million, respectively, of deferred tax assets. The deferred tax assets resulted primarily from net operating losses and were fully offset by a valuation allowance. The net operating losses will expire beginning in 2015 and the proceeding 20 years.
	Pretax income (loss) from domestic and foreign sources is as follows (dollars in thousands):
			Year Ended December 31
			2014			2013
	Domestic		$	122,727		$	82,529
	Foreign		578			(4,381		)
	Income before income taxes		$	123,305		$	78,148
	In September 2013, the Internal Revenue Service and Treasury Department released final 263(a) regulations regarding the deduction and capitalization of expenditures related to tangible property. The application of the new regulations to the 2014 taxable year did not materially affect our income tax provision.
Income Tax Uncertainties
We file federal income tax returns in the U.S. and Canada as well as various state and local income tax returns. Tax years 2011 to present remain open to examination in the U.S. and tax years 2010 to present remain open to examination in Canada and various states. As discussed above, prior to January 1, 2013, we were a limited liability company. Therefore, with limited exceptions, tax years prior to 2013 are the responsibility of the members of BC Holdings and not Boise Cascade.
We recognize tax liabilities and adjust these liabilities when our judgment changes as a result of the evaluation of new information not previously available or as new uncertainties occur. As of December 31, 2014, we had $0.3 million of unrecognized tax benefits attributable to research and development tax credits recorded on our Consolidated Balance Sheets, and we do not expect a significant change over the next twelve months. If all uncertain tax benefits were recognized, $0.3 million would benefit the effective tax rate. We had no unrecognized tax benefits recorded as of December 31, 2013.
We recognize interest and penalties related to uncertain tax positions as income tax expense in our Consolidated Statements of Operations. For the years ended December 31, 2014, 2013, and 2012, we recognized an insignificant amount of interest and penalties related to taxes.

Net Income Per Common Share	12 Months Ended
	Dec. 31, 2014
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 vested restricted stock units (RSUs) granted to nonemployee directors as there are no conditions under which those shares will not be issued. For more information about common share activity during the period, see Note 9, Stockholders' Equity. Diluted net income per common share is computed by dividing net income by the combination of other potentially dilutive weighted average common shares and the weighted average number of common shares outstanding during the period. Other potentially dilutive weighted average common shares include the dilutive effect of stock options, RSUs, and performance stock units (PSUs) for each period using the treasury stock method. Under the treasury stock method, the exercise price of a share, the amount of compensation expense, if any, for future service that has not yet been recognized, and the amount of tax benefits that would be recorded in additional paid-in-capital, if any, when the share is exercised 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:
		Year Ended December 31
		2014		2013		2012
		(thousands, except per-share data)
	Net income	$	80,009	$	116,936	$	41,496
	Weighted average common shares outstanding during the period (for basic calculation)	39,412		40,203		29,700
	Dilutive effect of other potential common shares	80		23		—
	Weighted average common shares and potential common shares (for diluted calculation)	39,492		40,226		29,700
	Net income per common share - Basic	$	2.03	$	2.91	$	1.4
	Net income per common share - Diluted	$	2.03	$	2.91	$	1.4
	The computation of the dilutive effect of other potential common shares excludes stock awards representing 0.2 million and 0.1 million shares of common stock in the years ended December 31, 2014 and 2013, respectively, and no shares of common stock in the year ended December 31, 2012. Under the treasury stock method, the inclusion of these stock awards would have been antidilutive.

	Asset-Based Revolving Credit Facility
	Boise Cascade and its principal operating subsidiaries, Boise Cascade Wood Products, L.L.C., and Boise Cascade Building Materials Distribution, L.L.C., are borrowers, and Boise Cascade Wood Products Holdings Corp. is guarantor under a $350 million senior secured asset-based revolving credit facility (Revolving Credit Facility), with a maturity date of July 31, 2018. Borrowings under the Revolving Credit Facility are constrained by a borrowing base formula dependent upon levels of eligible receivables and inventory reduced by outstanding borrowings and letters of credit (Availability). On February 6, 2014, we entered into a sixth amendment to our Revolving Credit Facility that primarily provides more administrative flexibility and reduces the notice period we must provide to receive London Interbank Offered Rate (LIBOR) based advances under the facility.
	The Revolving Credit Facility 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.
	Interest rates under the Revolving Credit Facility are based, at the company's election, on either the London Interbank Offered Rate (LIBOR) or a base rate, as defined in the credit agreement, plus a spread over the index elected that ranges from 1.50% to 2.00% for loans based on LIBOR and from 0.50% to 1.00% 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 ranging from 0.25% to 0.375% per annum (based on facility utilization) of the average unused portion of the lending commitments.
	The Revolving Credit Facility contains customary nonfinancial covenants, including a negative pledge covenant and restrictions on new indebtedness, investments, distributions to equityholders, asset sales, and affiliate transactions, the scope of which are dependent on the Availability existing from time to time. The Revolving Credit Facility 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 lending commitments (or $35 million). Availability exceeded the minimum threshold amounts required for testing of the FCCR at all times since entering into the Revolving Credit Facility, and Availability at December 31, 2014, was $266.8 million.
	The Revolving Credit Facility generally permits dividends only if certain conditions are met, including complying with either (i) pro forma Excess Availability (as defined in the Revolving Credit Facility) equal to or exceeding 25% of the aggregate Revolver Commitments (as defined in the Revolving Credit Facility) or (ii) (x) pro forma Excess Availability equal to or exceeding 15% of the aggregate Revolver Commitment and (y) a fixed-charge coverage ratio of 1:1 on a pro forma basis.
	At both December 31, 2014 and 2013, we had no borrowings outstanding under the Revolving Credit Facility and $8.0 million and $8.4 million, respectively, of letters of credit outstanding. These letters of credit and borrowings, if any, reduced our borrowing capacity under the Revolving Credit Facility by an equivalent amount. The maximum borrowings under the Revolving Credit Facility were $15.6 million during the year ended December 31, 2014. During the year ended December 31, 2014, the average interest rate on borrowings was approximately 1.65%.
	Senior Notes
	On October 22, 2012, Boise Cascade and its wholly owned subsidiary, Boise Cascade Finance Corporation (Boise Finance and together with Boise Cascade, the Co-issuers), issued $250 million of 6.375% senior notes due November 1, 2020 (Senior Notes) through a private placement that was exempt from the registration requirements of the Securities Act of 1933, as amended (Securities Act). Interest on our Senior Notes is payable semiannually in arrears on May 1 and November 1. On March 28, 2013, Boise Finance was merged with and into Boise Cascade, with Boise Cascade as the surviving entity and sole issuer of the Senior Notes. The Senior Notes are guaranteed by each of our existing and future direct or indirect domestic subsidiaries that is a guarantor or co-borrower under our Revolving Credit Facility.
	On August 15, 2013, we issued an additional $50 million in aggregate principal amount of Senior Notes in a private offering that was exempt from registration under the Securities Act. The additional $50 million of Senior Notes were priced at 103.5% of their principal amount plus accrued interest from May 1, 2013, and were issued as additional Senior Notes under the indenture dated as of October 22, 2012.
	On May 8, 2013 and November 26, 2013, we completed an offer to exchange any and all of our $250 million and $50 million, respectively, outstanding Senior Notes for a like principal amount of new 6.375% Senior Notes due 2020 having substantially identical terms to those of the Senior Notes. $250 million and $49,990,000 in aggregate principal amount (or 100% and 99.98%, respectively) of the outstanding Senior Notes were tendered and accepted for exchange upon closing of the related exchange offers and have been registered under the Securities Act.
	The Senior 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 Revolving Credit Facility 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 Senior Notes.
	The terms of the indenture governing the Senior Notes, among other things, limit the ability of Boise Cascade Company and certain Boise Cascade Company 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 Senior Notes provides for customary events of default, which include (subject in certain cases to customary grace and cure periods and notification requirements) among others: nonpayment of principal or interest; breach of other agreements in the indenture governing the Senior Notes; defaults in failure to pay certain other indebtedness; the rendering of judgments to pay certain amounts of money against the Co-issuers, the guarantors, or certain Boise Cascade subsidiaries; the failure of certain guarantees to be enforceable; and certain events of bankruptcy or insolvency.
	Cash Paid for Interest
	For the years ended December 31, 2014, 2013, and 2012, cash payments for interest were $20.2 million, $18.4 million, and $18.1 million, respectively.

As of December 31, 2014, we have one qualified defined benefit pension plan, which includes the merging of a salaried plan and two plans for hourly employees to simplify administration of the plans. The following summarizes recent activity of each individual plan:
	•	Benefits for salaried employees were frozen so that no future benefits have accrued since December 31, 2009.
	•	From 2011 through 2014, plan amendments affected certain union and non-union hourly employees by closing participation and freezing future benefits. The benefit for hourly employees is generally based on a fixed amount per year of service (years of service determined as of the freeze dates). In connection with these amendments, we recognized $0.2 million and $0.3 million, respectively, of noncash curtailment losses during the years ended December 31, 2013 and 2012. As a result, only certain hourly employees continue to accrue benefits after the effective dates of these amendments.
	We also have nonqualified salaried pension plans, which were frozen so that no future benefits have accrued since December 31, 2009.
	Defined Contribution Plans
	We sponsor contributory defined contribution savings plans for most of our salaried and hourly employees, and we generally provide company contributions to the savings plans. Since March 1, 2010, we have contributed 4% of each salaried participant's eligible compensation to the plan as a nondiscretionary company contribution. In addition, beginning in 2012, for the years that a performance target is met, we will contribute an additional amount of the employee's eligible compensation, depending on company performance and the employee's years of service. During the years ended December 31, 2014, 2013, and 2012, company performance resulted in additional contributions in the range of 1% to 2%, 1% to 2%, and 3% to 5%, respectively. The company contributions for union and nonunion hourly employees vary by location. Company contributions paid, or to be paid, to our defined contribution savings plans for the years ended December 31, 2014, 2013, and 2012, were $13.6 million, $13.2 million, and $14.3 million, respectively.
	Defined Contributory Trust
	We have participated in a multiemployer defined contributory trust plan for certain union hourly employees since 2013. As of December 31, 2014 and 2013, approximately 1,378 and 647, respectively, of our employees participated in this plan. For certain of these employees, per the terms of the representative collective bargaining agreements, we were required to contribute $0.50 and $0.45, respectively, per hour per active employee during 2014 and 2013. For certain other of these employees, we were required to contribute 4% of the employee's earnings during 2014. Company contributions to the multiemployer defined contributory trust plan for the years ended December 31, 2014 and 2013, were $2.1 million and $0.6 million, respectively. After required contributions, we have no further obligation to the plan. The plan and its assets are managed by a joint board of trustees.
	Deferred Compensation Plan
	We sponsor a deferred compensation plan. No compensation deferrals were allowed to be made under the plan from 2009 until our conversion from a limited liability company to a corporation in 2013, as deferrals to the plan were prohibited because Boise Cascade, L.L.C., was a disqualified entity under Internal Revenue Code Section 457A. Deferrals, company match, and interest on contributions made to the plan on or before December 31, 2008, were not affected by 457A. In July 2013, the deferred compensation plan was amended to effect certain administrative updates, and employee deferrals to the deferred compensation plan began again on January 1, 2014.
	Under the plan, participating employees irrevocably elect each year to defer receipt of a portion of their base salary and incentive compensation. A participant's account is credited with imputed interest at a rate equal to 130% of Moody's Composite Average of Yields on Corporate Bonds. Participants may receive payment of their deferred compensation plan balance in a lump sum or in monthly installments over a specified period of years following the termination of their employment with the company. The deferred compensation plan is unfunded; therefore, benefits are paid from our general assets.
	We recognized $0.6 million of interest expense related to the plan for each of the years ended December 31, 2014, 2013, and 2012. At December 31, 2014 and 2013, we had $10.7 million and $10.9 million, respectively, of liabilities related to the plan, of which $1.4 million and $1.8 million, respectively, were recorded in "Accrued liabilities, Compensation and benefits" and $9.3 million and $9.1 million, respectively, were recorded in "Other, Compensation and benefits" on our Consolidated Balance Sheets.
	Multiemployer Health and Welfare Plan
	We participate in a multiemployer health and welfare plan that covers medical, dental, and life insurance benefits for certain active employees as well as benefits for retired employees. As of December 31, 2014, approximately 652 of our employees participated in this plan. Per the terms of the representative collective bargaining agreements, we were required to contribute $5.50 per hour per active employee through May 31, 2012. From June 1, 2012 to May 31, 2014, we were required to contribute $5.00 per hour per active employee. Since June 1, 2014, we are required to contribute $5.25 per hour per active employee. Company contributions to the multiemployer health and welfare plan for the years ended December 31, 2014, 2013, and 2012, were $7.3 million, $6.9 million, and $6.7 million, respectively. After required contributions, we have no further obligation to the plan. The trustees of the plan determine the allocation of benefits between active and retired employees.
	Defined Benefit Obligations and Funded Status
	The following table, which includes only company-sponsored defined benefit plans, reconciles the beginning and ending balances of our projected benefit obligation and fair value of plan assets. We recognize the underfunded status of our defined benefit pension plans on our Consolidated Balance Sheets. We recognize changes in funded status in the year changes occur through other comprehensive income (loss).

	(a)	Benefits paid during the year ended December 31, 2014 includes approximately $15 million of lump-sum cash payments to certain terminated and vested participants in settlement of pension obligations.
	The accumulated benefit obligation for all defined benefit pension plans was $513.8 million and $443.3 million at December 31, 2014 and 2013, respectively. All of our defined benefit pension plans have accumulated benefit obligations that exceed the fair value of plan assets.
	Net Periodic Benefit Cost and Other Comprehensive (Income) Loss
	The components of net periodic benefit cost and other amounts recognized in other comprehensive (income) loss are as follows:
		Year Ended December 31

Total recognized in net periodic cost and other comprehensive (income) loss	$	75,877			$	(95,688	)		$	13,037
In 2015, we estimate net periodic pension expense will be approximately $6.3 million, including $6.4 million of net actuarial loss that will be amortized from accumulated other comprehensive loss.
Assumptions
The assumptions used in accounting for our plans are estimates of factors that will determine, among other things, the amount and timing of future contributions. The following table presents the assumptions used in the measurement of our benefit obligations:
	31-Dec
	2014			2013
Weighted average assumptions
Discount rate	3.75	%		4.65	%
Rate of compensation increases (a)	—	%		—	%
The following table presents the assumptions used in the measurement of net periodic benefit cost:

Rate of compensation increases (a)		—	%		—	%		—	%
_______________________________________
(a)	Pension benefits for all salaried employees are frozen, resulting in an assumption for the rate of compensation increase of zero. In addition to the salaried benefits being frozen, there are currently no scheduled increases in pension benefit rates applicable to past service covering hourly employees who continue to accrue benefits.
Discount Rate Assumption. The discount rate reflects the current rate at which the pension obligations could be settled based on the measurement date of the plans — December 31. In all years presented, the discount rates were determined by matching the expected plan benefit payments against a spot rate yield curve constructed to replicate the yields of Aa-graded corporate bonds.
Asset Return Assumption. We base our expected long-term rate of return on plan assets on a weighted average of our expected returns for the major asset classes (equities, fixed-income securities, a hedge fund, and real estate) in which we invest. The weights we assign each asset class are based on our investment strategy. Expected returns for the asset classes are based on long-term historical returns, inflation expectations, forecasted gross domestic product, earnings growth, and other economic factors. We developed our return assumption based on a review of the fund manager's estimates of future market expectations by broad asset class, actuarial projections, and expected long-term rates of return from external investment managers. The weighted average expected return on plan assets we will use in our calculation of 2015 net periodic benefit cost is 6.15%.
Retirement and Mortality Rates. These rates are developed to reflect actual and projected plan experience. In 2014, we used the new RP-2014 mortality tables along with the new two-dimensional mortality improvement scale MP-2014. In 2013, we used the RP-2000 mortality tables. The new tables reflect updated projected mortality rates based on actuarial studies by the Society of Actuaries.
Investment Policies and Strategies
At December 31, 2014, 56% of our pension plan assets were invested in equity securities, 35% in fixed-income securities, 4% in a hedge fund, and 5% in real estate. The general investment objective for all of our plan assets is to optimize growth of the pension plan trust assets, while minimizing the risk of significant losses in order to enable the plans to satisfy their benefit payment obligations over time. The objectives take into account the long-term nature of the benefit obligations, the liquidity needs of the plans, and the expected risk/return trade-offs of the asset classes in which the plans may choose to invest. The Retirement Funds Investment Committee is responsible for establishing and overseeing the implementation of our investment policy. Russell Investments (Russell) oversees the active management of our pension investments through its manager of managers program in order to achieve broad diversification in a cost-effective manner. At December 31, 2014, our investment policy governing our relationship with Russell allocated 30% to large-capitalization U.S. equity securities, 5% to small- and mid-capitalization U.S. equity securities, 21% to international equity securities, 35% to fixed-income securities, 4% to a hedge fund, and 5% to real estate. Our arrangement with Russell allows monthly rebalancing to the policy targets noted above.
Investment securities, in general, are exposed to various risks, such as interest rate, credit, and overall market volatility risk, all of which are subject to change. In addition, our overall investment strategy and related allocations between equity and fixed-income securities may change from time to time based on market conditions, external economic factors, and the funded status of our plans. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term, and such changes could materially affect the reported amounts.

_______________________________________
(a)	Equity and fixed-income securities represent common collective trusts managed by Russell Trust Company. The funds are valued at the net asset value (NAV) provided by Russell Trust Company, the administrator of the funds. The NAV is a practical expedient for fair value and is based on the value of the assets owned by the fund, less liabilities at year-end. While the underlying assets are actively traded on an exchange, the funds are not. We have the ability to redeem these equity and fixed-income securities with a one-day notice.
(b)	Invested in the Russell Equity I Fund at December 31, 2014 and 2013. The fund seeks returns that exceed the Russell 1000 Index by investing in large-capitalization stocks of the U.S. stock market. In addition, at December 31, 2014 and 2013, our investments in this category included the Russell 1000 Index Fund, which seeks to track the investment results of an index composed of large- and mid-capitalization stocks of the U.S. stock market.
(c)	Invested in the Russell Equity II Fund. The fund seeks returns that exceed the Russell 2500 Index by investing in the small- and mid-capitalization stocks of the U.S. stock market.
(d)	Invested in the Russell International Fund with Active Currency at December 31, 2014 and 2013, which benchmarks against the Russell Developed ex-U.S. Large Cap Index Net and seeks favorable total returns and additional diversification through investment in non-U.S. equity securities and active currency management. The fund participates primarily in the stock markets of Europe and the Pacific Rim and seeks to opportunistically add value through active investment in foreign currencies. In addition, at December 31, 2014 and 2013, our investments in this category included the Russell Emerging Market Fund, which benchmarks against the Russell Emerging Markets Index and is designed to maintain a broadly diversified exposure to emerging market countries. At December 31, 2014 and 2013, investments in emerging markets represent approximately 23% and 20%, respectively, of our international portfolio.
(e)	Invested in the Russell Multi-Manager Bond Fund at December 31, 2014 and 2013. The fund seeks to outperform the Barclays Capital U.S. Aggregate Bond Index over a full market cycle. The fund is designed to provide current income and, as a secondary objective, capital appreciation through a variety of diversified strategies, including sector rotation, modest interest rate timing, security selection, and tactical use of high-yield and emerging market bonds. In addition, at December 31, 2014, our investments in this category included the Russell Long Duration Fixed Income Fund, which is designed to provide maximum total return through diversified strategies including sector rotation, modest interest rate timing, security selection, and tactical use of high-yield, emerging market bonds and other non-index securities.
(f)	The fund seeks to produce high risk-adjusted returns while targeting a low long-term average correlation to traditional markets. The fund invests internationally in a broad range of instruments, including, but not limited to, equities, currencies, convertible securities, futures, forwards, options, swaps, and other derivative products. The fair value of the hedge fund is estimated using the NAV of the investments as a practical expedient for fair value. We have the ability to redeem these investments at NAV within the near term, and they are thus classified within Level 2.
(g)	Invested in the Russell Real Estate Equity Fund. Real estate investments include those in limited partnerships that invest in various domestic commercial and residential real estate projects. The fair values of real estate assets are typically determined by using income and/or cost approaches or a comparable sales approach, taking into consideration discount and capitalization rates, financial conditions, local market conditions, and the status of the capital markets, and they are thus classified within Level 3. Notwithstanding the above, the variety of valuation bases adopted and quality of management data of the underlying assets means that there are inherent difficulties in determining the value of the investments. Amounts realized on the sale of these investments may differ from the calculated values. We have the ability to redeem the real estate investments with a 110-calendar-day written notice prior to a quarterly trade date.
The following table sets forth a summary of changes in the fair value of the pension plans' Level 3 assets for the years ended December 31, 2014 and 2013:
		31-Dec
		2014				2013
		(thousands)
Balance, beginning of year		$	16,055			$	14,310

Balance, end of year		$	17,802			$	16,055
Cash Flows
On August 26, 2013 and July 13, 2012, we contributed company-owned real property to the pension plans from certain locations in our Building Materials Distribution segment. The pension plans obtained independent appraisals of the properties, and based on these appraisals, the plans recorded the contributions at fair value of $4 million and $10 million, respectively, during the years ended December 31, 2013 and 2012.
We are leasing back the contributed properties for an initial term of ten years with two five-year extension options and continue to use the properties in our distribution operations. Rent payments are made quarterly, with first-year annual rents of $1.1 million and 2% annual escalation rates thereafter. Each lease provides us a right of first refusal on any subsequent sale by the pension plans, as well as repurchase options at the end of the initial term and extension periods. The plans engaged an independent fiduciary who negotiated the lease terms and also manages the properties on behalf of the plans.
We determined that the contribution of the properties does not meet the accounting definition of a plan asset within the scope of Accounting Standards Codification 715, Compensation — Retirement Benefits. Accordingly, the contributed properties are not considered a contribution for accounting purposes and, as a result, are not included in plan assets and have no impact on the net pension liability recorded on our Consolidated Balance Sheets. We continue to depreciate the carrying value of the properties in our financial statements, and no gain or loss was recognized at the contribution date for accounting purposes. Lease payments are recorded as pension contributions.
Our practice is to fund the pension plans in amounts sufficient to meet the minimum requirements of U.S. federal laws and regulations. Additional discretionary funding may be provided as deemed appropriate. For the years ended December 31, 2014, 2013, and 2012, we made cash contributions to our pension plans totaling $12.1 million, $10.7 million, and $8.5 million, respectively. Cash contributions in 2014, 2013, and 2012 include $1.1 million, $1.0 million, and $0.4 million, respectively, of lease payments. The total cash contributions satisfied U.S. Department of Labor minimum pension contribution requirements for 2014. While we have no required contributions for 2015, we expect to make cash contributions of approximately $15 million to our pension plans.
The following benefit payments are expected to be paid to plan participants. Qualified pension benefit payments are paid from plan assets, while nonqualified pension benefit payments are paid by the company.

Stock-Based Compensation	12 Months Ended

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation
	In connection with our initial public offering, we adopted the 2013 Incentive Compensation Plan (2013 Incentive Plan). The 2013 Incentive Plan provides for grants of stock options, stock appreciation rights, restricted stock, other stock-based awards, other cash-based compensation, and performance awards. Directors, officers, and other employees, as well as others performing consulting or advisory services for us, are eligible for grants under the 2013 Incentive Plan. These awards are at the discretion of the Compensation Committee of our board of directors, and they vest and expire in accordance with terms established at the time of grant. All awards under the 2013 Incentive Plan are eligible to participate in dividend or dividend equivalent payments, if any, which we would accrue to be paid when the awards vest.
	Shares issued pursuant to awards under the 2013 Incentive Plan are from our authorized but unissued shares. The maximum number of shares approved for grant under the 2013 Incentive Plan is 3.1 million shares. We issue new shares of common stock upon exercise of stock options and vesting of other stock-based awards. As of December 31, 2014, 2.6 million shares remained available for future issuance under the 2013 Incentive Plan.
	In February 2014, we granted two types of stock-based awards under the 2013 Incentive Plan: performance stock units (PSUs) and restricted stock units (RSUs). In February 2013, we granted three types of stock-based awards under the 2013 Incentive Plan: PSUs, RSUs, and stock options.
	PSU and RSU Awards
	In 2014, we granted 100,692 PSUs to our officers and other employees, subject to performance and service conditions. The number of shares actually awarded will range from 0% to 200% of the target amount, depending upon Boise Cascade's 2014 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 and subject to final determination of 2014 EBITDA by the Compensation Committee of our board of directors. Because the EBITDA component contains a performance condition, we record compensation expense, net of estimated forfeitures, over the requisite service period based on the most probable number of shares expected to vest.
	In 2013, we granted 90,124 PSUs to our officers and other employees, subject to performance and service conditions. During the 2013 performance period, participants earned 112% of the target based on Boise Cascade’s 2013 EBITDA, determined by our Compensation Committee in accordance with the related grant agreement.
	In 2014, we granted an aggregate of 128,497 RSUs to our officers, other employees, and nonemployee directors with only service conditions. In 2013, we granted an aggregate of 14,161 RSUs to our nonemployee directors with only service conditions.
	The PSUs, if earned, vest in three equal tranches on December 31 of each year after the grant date, subject to final determination of meeting the performance condition by the Compensation Committee of our board of directors. The RSUs granted to officers and other employees vest in three equal tranches on December 31 of each year after the grant date. However, 100% of PSUs and RSUs granted to retirement-eligible employees (age 62 or older with 15 years of service, or age 65 or older) vest on the later of December 31 after grant date or the date upon which they become retirement eligible. The RSUs granted to nonemployee directors vest over a one-year period, provided that such vested shares will not be delivered to the directors until six months following termination from the board of directors.
	We based the fair value of PSU and RSU awards on the closing market price of our common stock on the grant date, and we record compensation expense over the awards' vesting period. Any shares not vested are forfeited. During the year ended December 31, 2014, the total fair value of PSUs and RSUs vested was $4.6 million.
	The following summarizes the activity of our PSUs and RSUs awarded under the 2013 Incentive Plan for the year ended December 31, 2014:
			PSUs					RSUs

	Stock Options
	In February 2013, we granted 161,257 nonqualified stock options to our officers and other employees, subject to service conditions. The stock options generally vest and become exercisable on a pro rata basis over a three-year period from the date of grant. Our stock options generally have a contractual term of ten years, meaning the option must be exercised by the holder before the tenth anniversary of the grant date, subject to earlier expiration for vested options not exercised following termination of employment. The following is a summary of our stock option activity:
			Number of Options		Weighted Average Exercise Price Per Option			Weighted Average Remaining Contractual Life		Aggregate Intrinsic Value

	Exercisable, December 31, 2014		45,276		$	27.19		8.2		$	451
	During the year ended December 31, 2014, the total intrinsic value of stock options exercised was $0.1 million. Cash received from stock options exercised was $0.2 million for the year ended December 31, 2014, with an immaterial amount of actual tax benefit realized from stock options exercised.
	The fair value for stock option awards was estimated at the grant date using the Black-Scholes option valuation model with the following weighted average assumptions:
		Year Ended December 31, 2013
	Expected volatility	60.9		%
	Expected life (in years)	6
	Risk-free interest rate	1		%
	Expected dividends	—
	Weighted average fair value per option granted	$	14.87
	The expected volatility of our stock price is based on the volatility of related industry stocks. As these 2013 grants were our first issuances of stock options and our equity shares have been traded for a short period of time, we did not have sufficient historical data to provide a reasonable basis upon which to estimate the expected life. Therefore, we used the simplified method allowed by the Securities and Exchange Commission. The risk-free interest rate is based on the yields of U.S. Treasury issues with terms similar to the expected life of the options.
	Compensation Expense
	Stock-based compensation expense is recognized only for those awards that are expected to vest, with forfeitures estimated at the date of grant based on our historical experience and future expectations. We recognize the effect of adjusting the estimated forfeiture rates in the period in which we change such estimated rates. 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, RSUs, and stock options net of estimated forfeitures, was as follows:
			Year Ended December 31
			2014			2013
			(thousands)
	PSUs		$	3,169		$	1,932
	RSUs		2,018			274
	Stock options		729			663
	Total		$	5,916		$	2,869
	The related tax benefit for the years ended December 31, 2014 and 2013, was $2.2 million and $1.1 million, respectively. As of December 31, 2014, total unrecognized compensation expense related to nonvested share-based compensation arrangements was $3.6 million, net of estimated forfeitures. This expense is expected to be recognized over a weighted-average period of 1.5 years.

Stockholders' Equity	12 Months Ended

Stockholders' Equity Note [Abstract]
Stockholders' Equity	Stockholders' Equity
	Upon our conversion from a limited liability company to a corporation, our certificate of incorporation authorized 300,000,000 shares of common stock and 50,000,000 shares of preferred stock. No preferred stock was issued or outstanding as of December 31, 2014 and 2013. We had 43,282,201 and 43,229,412 shares of common stock issued and 39,418,139 and 39,365,350 shares of common stock outstanding as of December 31, 2014 and 2013, respectively. Each share of common stock entitles the holder to one vote on matters to be voted on by the stockholders of Boise Cascade.
	On February 11, 2013, we issued 13,529,412 shares of common stock in our initial public offering. Following this initial public offering, we received proceeds of $262.5 million, after deducting underwriting discounts and commissions of $19.2 million and offering expenses of $2.5 million. On July 30, 2013, we repurchased 3,864,062 shares of common stock from BC Holdings for $100.0 million funded with cash on hand, which shares are recorded as "Treasury stock" on our Consolidated Balance Sheet.
	See Note 3, Income Taxes, for a discussion of our conversion from a limited liability company to a corporation. The common stock authorized and outstanding, par values, net income per share amounts, and other per-share disclosures for all periods presented have been adjusted to reflect the impact of this conversion. Upon this conversion, we reclassified $32.0 million of accumulated deficits through February 4, 2013, to additional paid-in capital.
	Redeemable Equity
	Redeemable equity represented equity units of Forest Products Holdings, L.L.C. (FPH), former majority owner of BC Holdings, held by certain members of our senior management team, which units were redeemable at the option of the holder in the event of death or disability or the sale of a division resulting in the termination of his or her employment. We had historically classified these units outside of our permanent equity because these units were subject to mandatory redemption (and could have been subject to repayment by us) upon an event outside our control (i.e., death or disability). In 2012, we reclassified certain redeemable equity units into "Stockholders' Equity" on our Consolidated Balance Sheets, which resulted from employee retirements or terminations causing the equity units to no longer be subject to mandatory redemption in an event that is outside of BC Holdings' control. In 2013, following our initial public offering, we reclassified the remaining equity units as permanent equity because we no longer have an obligation to satisfy this redemption obligation on FPH's behalf.
	Distributions
	In 2012, we made $228.3 million of cash distributions to BC Holdings. Both our senior credit facility and the indenture governing our senior subordinated notes permitted these distributions. In 2014 and 2013, we did not make any cash distributions.
	Accumulated Other Comprehensive Loss

	On September 30, 2013, our wholly owned subsidiary, Boise Cascade Wood Products, L.L.C., completed the acquisition of 100% of the outstanding limited liability company interests of both Chester Wood Products LLC and Moncure Plywood LLC (Wood Resources LLC Southeast Operations) for an aggregate purchase price of $103.0 million, including a post-closing adjustment of $1.0 million based upon a working capital target (the Acquisition).
	The following pro forma financial information presents the combined results of operations as if the Wood Resources LLC Southeast Operations had been combined with us on January 1, 2012. The pro forma financial information also gives effect to the issuance of $50 million in aggregate principal amount of Senior Notes on August 15, 2013, and the $25.0 million borrowed under our revolving credit facility to partially finance the Acquisition, as if such transactions had occurred on January 1, 2012. The pro forma results are intended for information purposes only and do not purport to represent what the combined companies' results of operations would actually have been had the related transactions in fact occurred on January 1, 2012. They also do not reflect any cost savings, operating synergies, or revenue enhancements that we may achieve or the costs necessary to achieve those cost savings, operating synergies, revenue enhancements, or integration efforts.

Outsourcing Services Agreement [Abstract]
Outsourcing services agreement	Outsourcing Services Agreement
	Under an Outsourcing Services Agreement, a wholly-owned subsidiary of Packaging Corporation of America (PCA) provides a number of corporate staff services to us. These services include, but are not limited to, information technology, accounting, and human resource transactional services. On November 17, 2014, we entered into the Fifth Amendment to Outsourcing Services Agreement (the “Amendment”) with PCA, which amends the Outsourcing Services Agreement, dated February 22, 2008 (the “Agreement”), to, among other things, provide expiration dates for the termination of substantially all administrative services provided by PCA to us pursuant to the Agreement. For those services scheduled to be terminated, the expiration dates are planned to occur between March 2015 and December 2015. Services for which the Amendment does not provide expiration dates will generally continue under the same terms and conditions of the Agreement. These administration services will transition from PCA to us upon expiration. During and after transition, our information technology systems will remain in place with many of the administrative services performed by newly hired employees, many of whom we expect to transition from PCA to Boise Cascade employment. Total expenses incurred under the Outsourcing Services Agreement were $15.1 million, $15.5 million, and $15.0 million, respectively, for the years ended December 31, 2014, 2013, and 2012. The majority of these expenses are recorded in "General and administrative expenses" in our Consolidated Statements of Operations.

Related Party Transactions [Abstract]
Transactions With Related Parties	Transactions With Related Parties
	Louisiana Timber Procurement Company, L.L.C. (LTP) is an unconsolidated variable-interest entity that is 50% owned by us and 50% owned by 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 $28.7 million, $22.1 million, and $19.8 million, respectively, during the years ended December 31, 2014, 2013, and 2012. These pulpwood and chip sales were made at prices designed to approximate market. These sales are recorded in "Sales" in our Consolidated Statements of Operations.
	Costs and Expenses
	Related-party wood fiber purchases from LTP were $75.8 million, $67.5 million, and $60.3 million, respectively, during the years ended December 31, 2014, 2013, and 2012. We purchased wood fiber at prices designed to approximate market. These costs are recorded in "Materials, labor, and other operating expenses (excluding depreciation)" in our Consolidated Statements of Operations.

Financial Instrument Risk [Abstract]
Financial Instrument Risk	Financial Instrument Risk
	In the normal course of business, we are exposed to financial risks such as changes in interest rates, foreign currency exchange rates, and commodity price risk. In 2014, 2013, and 2012, we did not use derivative instruments.
	Interest Rate Risk
	When we have loan amounts outstanding on our Revolving Credit Facility, we are exposed to interest rate risk arising from fluctuations in interest rates.
	Foreign Currency Risk
	We have sales in countries outside the United States. As a result, we are exposed to movements in foreign currency exchange rates, primarily in Canada, but we do not believe our exposure to currency fluctuations is significant.
	Commodity Price Risk
	Many of the products we manufacture or purchase and resell and some of our key production inputs are commodities whose price is determined by the market's supply and demand for such products. Price fluctuations in our selling prices and key costs have a significant effect on our financial performance. The markets for most of these commodities are cyclical and are primarily affected by various economic and industry factors, including the strength of the U.S. housing market, changes in or disruptions to industry production capacity, changes in inventory levels, and other factors beyond our control.

Segment Reporting [Abstract]
Segment Information	Segment Information
	We operate our business using three reportable segments: Wood Products, Building Materials Distribution, and Corporate and Other. These segments represent distinct businesses that are managed separately because of differing products and services. Each of these businesses requires distinct operating and marketing strategies. Management reviews the performance of the company based on these segments.
	Our Wood Products segment manufactures structural, appearance, and industrial plywood panels. In addition, we manufacture engineered wood products (EWP), consisting of laminated veneer lumber (LVL), I-joists, and laminated beams, which are structural products used in applications where extra strength and consistent quality are required, such as headers and beams. LVL is also used in the manufacture of I-joists, which are assembled by combining a vertical web of oriented strand board (OSB) with top and bottom LVL or solid wood flanges. We also produce studs, particleboard, and ponderosa pine lumber. Our wood products are used primarily in new residential construction, residential repair-and-remodeling markets, and light commercial construction. The majority of our wood products are sold to leading wholesalers (including our Building Materials Distribution segment), home improvement centers, retail lumberyards, and industrial converters. During 2014, approximately 40% of Wood Products' overall sales were to our Building Materials Distribution segment.
	Our Building Materials Distribution segment is a leading national stocking wholesale distributor of building materials. We distribute a broad line of building materials, including EWP, OSB, plywood, lumber, and general line items such as siding, metal products, insulation, roofing, and composite decking. Except for EWP, we purchase most of these building materials from third-party suppliers and market them primarily to retail lumberyards and home improvement centers that then sell the products to the final end customers, who are typically professional builders, independent contractors, and homeowners engaged in residential construction projects.
	Our Corporate and Other segment includes corporate support staff services, related assets and liabilities, and foreign currency exchange gains and losses. These support services include, but are not limited to, finance, accounting, legal, information technology, and human resource functions. We purchase many of these services from PCA, under an Outsourcing Services Agreement, under which PCA provides a number of corporate staff services to us. See Note 12, Outsourcing Services Agreement, for more information.
	The segments' profits and losses are measured on operating profits and losses before interest expense and interest income. Specified expenses are allocated to the segments. For many of these allocated expenses, the related assets and liabilities remain in the Corporate and Other segment.
	The segments follow the accounting principles described in Note 2, Summary of Significant Accounting Policies.
	For the year ended December 31, 2014, no customers accounted for 10% or more of total sales. For the years ended December 31, 2013 and 2012, sales to one customer accounted for $350.9 million and $304.9 million, respectively, or approximately 11% of total sales for both periods. Sales to this customer were recorded in our Building Materials Distribution and our Wood Products segments.
	Sales to foreign unaffiliated customers were $76.2 million, $87.2 million, and $82.0 million for the years ended December 31, 2014, 2013, and 2012, respectively.
	At December 31, 2014, 2013, and 2012, and for the years then ended, long-lived assets located in foreign countries and net sales originating in foreign countries were not material.

(b)	EBITDA is defined as income (loss) before interest (interest expense and interest income), income taxes, and depreciation and amortization. EBITDA is the primary measure used by our chief operating decision maker to evaluate segment operating performance and to decide how to allocate resources to segments. We believe EBITDA is useful to investors because it provides a means to evaluate the operating performance of our segments and our company on an ongoing basis using criteria that are used by our internal decision makers and because it is frequently used by investors and other interested parties when comparing companies in our industry that have different financing and capital structures and/or tax rates. We believe EBITDA is a meaningful measure because it presents a transparent view of our recurring operating performance and allows management to readily view operating trends, perform analytical comparisons, and identify strategies to improve operating performance. EBITDA, however, is not a measure of our liquidity or financial performance under generally accepted accounting principles (GAAP) and should not be considered as an alternative to net income (loss), income (loss) from operations, or any other performance measure derived in accordance with GAAP or as an alternative to cash flow from operating activities as a measure of our liquidity. The use of EBITDA instead of net income (loss) or segment income (loss) has limitations as an analytical tool, including the inability to determine profitability; the exclusion of interest expense, interest income, and associated significant cash requirements; and the exclusion of depreciation and amortization, which represent unavoidable operating costs. Management compensates for the limitations of EBITDA by relying on our GAAP results. Our measure of EBITDA is not necessarily comparable to other similarly titled captions of other companies due to potential inconsistencies in the methods of calculation.
The following is a reconciliation of net income to EBITDA for the consolidated company:

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 5, Debt, and Note 6, 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 and fiber supply agreements. At December 31, 2014, our total obligation for log and fiber purchases under contracts with third parties was approximately $80 million based on fixed contract pricing or first quarter 2015 pricing for variable contracts. Under certain log and fiber 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 and fiber obligations 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 and fiber availability, and the status of environmental appeals. Except for deposits required pursuant to wood supply contracts, these obligations are not recorded in our consolidated financial statements until the contract payment terms take effect.
	We enter into contracts for the purchase of electricity and natural gas. We also purchase these services under utility tariffs. At December 31, 2014, we had approximately $13.8 million of energy purchase commitments. These payment obligations were valued either at market prices as of December 31, 2014, or at a fixed price, in each case in accordance with the terms of the related contract or tariff. Because we consume the energy in the manufacture of our products, these obligations represent the face value of the contracts, not resale value.
	Legal Proceedings and Contingencies
	We are a party to routine legal proceedings that arise in the ordinary course of our business. We are not currently a party to any legal proceedings or environmental claims that we believe would, 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, described in Note 5, Debt. Their obligations are guaranteed by each of our remaining domestic subsidiaries.
	Boise Cascade has issued $300.0 million of 6.375% senior notes due in 2020 (Senior Notes). At December 31, 2014, $300.0 million of the Senior Notes were outstanding. The Senior 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 5, 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 the obligations of Boise Cascade Wood Products, L.L.C., with respect to present and future timber sale agreements and several facility and rolling stock leases entered into by such subsidiaries and by Boise Cascade Building Materials Distribution, L.L.C. Boise Cascade's exposure under these agreements is limited to future timber purchases and the minimum lease payment requirements under the agreements. Boise Cascade also enters into guarantees of various raw material or energy supply agreements arising in the ordinary course of business.
	All surety bonds and most letters of credit supporting obligations of subsidiaries sold or liabilities assumed by Boise Inc., which became a wholly-owned subsidiary of PCA, in connection with the sale of our Paper and Packaging & Newsprint assets in 2008 have been replaced by new surety bonds or letters of credit issued without our credit support. The principal exception is letters of credit supporting workers' compensation obligations assumed by Boise Inc., which as a matter of state law must remain in our name even though the underlying liabilities and exposures have been assumed by Boise Inc. We are entitled to an indemnification from the purchaser for liabilities with respect to such letters of credit arising from workers' compensation claims assumed by Boise Inc. and for our costs of maintaining Boise Inc.'s share of any such letter of credit.
	We enter into a wide range of indemnification arrangements in the ordinary course of business. These include tort indemnifications, tax indemnifications, financing transactions, indemnifications against third-party claims arising out of arrangements to provide services to us, and indemnifications in merger and acquisition agreements. At December 31, 2014, we are unable to estimate the maximum potential liability under these indemnifications, and we are not aware of any material liabilities arising from these indemnifications.

Consolidating Guarantor and Nonguarantor Financial Information	12 Months Ended

Disclosure Text Block Supplement [Abstract]
Consolidating Guarantor and Nonguarantor Financial Information	Consolidating Guarantor and Nonguarantor Financial Information
	The following consolidating financial information presents the Statements of Comprehensive Income (Loss), Balance Sheets, and Statements of Cash Flows related to Boise Cascade. The Senior Notes are guaranteed fully and unconditionally and jointly and severally by each of our existing and future subsidiaries (other than our foreign subsidiaries). Each of our existing subsidiaries that is a guarantor of the Senior Notes is 100% owned by Boise Cascade. Other than the consolidated financial statements and footnotes for Boise Cascade and the consolidating financial information, financial statements and other disclosures concerning the guarantors have not been presented because management believes that such information is not material to investors. The reclassifications to net income from accumulated other comprehensive loss are recorded primarily in our guarantor subsidiaries.
	Furthermore, the cancellation provisions in the related indenture regarding guarantor subsidiaries are customary, and they do not include an arrangement that permits a guarantor subsidiary to opt out of the obligation prior to or during the term of the debt. Each guarantor subsidiary is automatically released from its obligations as a guarantor upon the sale of the subsidiary or substantially all of its assets to a third party, the designation of the subsidiary as an unrestricted subsidiary for purposes of the covenants included in the indenture, the release of the indebtedness under the indenture, or if the issuer exercises its legal defeasance option or the discharge of its obligations in accordance with the indenture governing the Senior Notes.
	On October 1, 2013, we entered into a supplemental indenture (Supplemental Indenture) with certain of our subsidiaries and U.S. Bank National Association, the trustee for our Senior Notes, to add Chester Wood Products LLC and Moncure Plywood LLC as guarantors of the Senior Notes. Entry into the Supplemental Indenture was consummated in connection with the Acquisition on September 30, 2013. As such, Chester Wood Products LLC and Moncure Plywood LLC are included as guarantor subsidiaries in the consolidating guarantor and nonguarantor financial statements effective October 1, 2013.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Principles of Consolidation [Policy Text Block]	Principles of Consolidation
	The consolidated financial statements include the accounts of Boise Cascade and its subsidiaries. Intercompany balances and transactions have been eliminated.
Use of Estimates [Policy Text Block]	Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 benefits; stock-based compensation; 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
	We recognize revenue when the following criteria are met: persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, our price to the buyer is fixed or determinable, and collectibility is reasonably assured. Delivery is not considered to have occurred until the customer takes title and assumes the risks and rewards of ownership. The timing of revenue recognition is dependent on shipping terms. Revenue is recorded at the time of shipment for terms designated free on board (fob) shipping point. For sales transactions designated fob destination, revenue is recorded when the product is delivered to the customer's delivery site.
Shipping and Handling Costs [Policy Text Block]	Fees for shipping and handling charged to customers for sales transactions are included in "Sales." For our Wood Products segment, costs related to shipping and handling are included in "Materials, labor, and other operating expenses (excluding depreciation)." 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 $104.8 million, $94.8 million, and $89.3 million are included primarily in "Selling and distribution expenses" for the years ended December 31, 2014, 2013, and 2012, respectively.
Cash and Cash Equivalents [Policy Text Block]	Cash and Cash Equivalents
	Cash equivalents consist of short-term investments that have a maturity of three months or less at the date of purchase. At December 31, 2014 and 2013, the majority of our cash and cash equivalents were invested in money market funds that are broadly diversified and invested in high-quality, short-duration securities, including commercial paper, certificates of deposit, U.S. government agency securities, and similar instruments. We have significant amounts of cash and cash equivalents that are in excess of federally insured limits. Though we have not experienced any losses on our cash and cash equivalents to date and we do not anticipate incurring any losses, we cannot be assured that we will not experience losses on our cash and cash equivalents.
Trade Accounts Receivables and Allowance for Doubtful Accounts [Policy Text Block]	Trade Accounts Receivables and Allowance for Doubtful Accounts
	Trade accounts receivable are stated at the amount we expect to collect. Trade accounts receivable do not bear interest. We make ongoing estimates relating to the collectibility of our accounts receivable and maintain a reserve for estimated losses resulting from the inability of our customers to meet their financial obligations to us. At December 31, 2014 and 2013, we had $2.1 million and $2.5 million, respectively, recorded as allowances for doubtful accounts. In determining the amount of the reserve and in order to manage credit risk, we consider our historical level of credit losses, customer concentrations, and current economic trends and monitor the creditworthiness of significant customers based on ongoing credit evaluations. Our sales are principally to customers in the building products industry located in the United States and Canada. A significant portion of our sales are concentrated with a relatively small number of customers. In 2014, our top ten customers represented approximately 28% of sales. At December 31, 2014 and 2013, receivables from a single customer accounted for approximately 11% and 13%, respectively, of total receivables. No other customer accounted for 10% or more of total receivables. Adjustments to the valuation allowance are charged to income. Trade accounts receivable balances that remain outstanding after we have used reasonable collection efforts are written off through a charge to the valuation allowance and a credit to accounts receivable. Although we have not experienced material credit losses in recent years, our actual future losses from uncollectible accounts may differ materially from our current estimates. As additional information becomes known, we may change our estimates. In the event we determine that a change in the reserve is appropriate, we will record a charge to "Selling and distribution expenses" in our Consolidated Statements of Operations in the period we make such a determination.
Fair Value [Policy Text Block]	Fair Value
	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy under U.S. generally accepted accounting principles (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). See Note 7, Retirement and Benefit Plans, for the fair value measurements of our defined benefit plans' assets.
Financial Instruments [Policy Text Block]	Financial Instruments
	Our financial instruments are cash and cash equivalents, accounts receivable, accounts payable, and long-term debt. Our cash is recorded at cost, which approximates fair value, and our cash equivalents are money market funds measured at fair value. As of December 31, 2014 and 2013, we held $137.6 million and $85.8 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 December 31, 2014, the book value of our fixed-rate debt was $300.0 million, and the fair value was estimated to be $315.0 million. 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 based on quoted market prices for similar traded debt (Level 2 measurement).
Vendor and Customer 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.
	We also provide rebates to our customers and our customers' customers based on the volume of their purchases. We provide the rebates to increase the sell-through of our products. The rebates are recorded as a decrease in "Sales."
Foreign Currency [Policy Text Block]	Foreign Currency
	The functional currency for our operations outside the United States is the U.S. dollar. Nonmonetary assets and liabilities and related depreciation and amortization for these foreign operations are remeasured into U.S. dollars using historical exchange rates. Monetary assets and liabilities are remeasured into U.S. dollars using the exchange rates as of the Consolidated Balance Sheet date. Revenue and expense items are remeasured into U.S. dollars using an average exchange rate prevailing during the year.
Leases [Policy Text Block]	Leases
	We assess lease classification as either capital or operating at lease inception or upon modification. We lease a portion of our distribution centers as well as other property and equipment under operating leases. Substantially all lease agreements have fixed payment terms based on the passage of time. Some lease agreements provide us with the option to purchase the leased property. Additionally, some agreements contain renewal options generally ranging from one to ten years, with fixed payment terms similar to those in the original lease agreements. 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 assured of exercising.
Inventory Valuation [Policy Text Block]	Inventory Valuation
	Inventories are valued at the lower of cost or market. Cost is based on the first-in, first-out (FIFO) method of inventory valuation or average cost. Manufactured inventories include costs for materials, labor, and factory overhead. Log inventories include costs to harvest and deliver the timber.
Property and Equipment [Policy Text Block]	Property and Equipment
	Property and equipment are recorded at cost. Cost includes expenditures for major improvements and replacements and the amount of interest cost associated with significant capital additions. For the years ended December 31, 2014, 2013, and 2012, we did not capitalize any interest. We expense all repair and maintenance costs as incurred. When property and equipment are retired, sold, or otherwise disposed of, the asset's carrying amount and related accumulated depreciation are removed from the accounts and any gain or loss is included in income (loss). We use the straight-line method of depreciation.
Long-Lived Asset Impairment [Policy Text Block]	Long-Lived Asset Impairment
	We review long-lived assets for impairment when events or changes in circumstances indicate that the carrying amount of assets may not be recoverable. An impairment of long-lived assets exists when the carrying value is not recoverable through future undiscounted cash flows from operations and when the carrying value of an asset or asset group exceeds its fair value.
Goodwill and Intangible Assets [Policy Text Block]	Goodwill and Intangible Assets
	We maintain two reporting units for purposes of our goodwill impairment testing, Wood Products and Building Materials Distribution, which are the same as our operating segments discussed in Note 15, Segment Information. We test goodwill in each of our reporting units and intangible assets with indefinite lives for impairment annually in the fourth quarter or sooner if events or changes in circumstances indicate that the carrying value of the asset may exceed fair value. We also evaluate the remaining useful lives of our finite-lived purchased intangible assets to determine whether any adjustments to the useful lives are necessary.
	We completed our annual assessment of goodwill in fourth quarter 2014 using a qualitative approach. The qualitative goodwill impairment assessment requires evaluating factors, based on the weight of evidence, to determine whether a reporting unit's carrying value would more likely than not exceed its fair value. As part of our goodwill qualitative testing process for each reporting unit, we evaluate various factors that are specific to the reporting unit as well as industry and macroeconomic factors in order to determine whether it is reasonably likely to have a material impact on the fair value of our reporting units. Examples of the factors that were considered include the results of the most recent quantitative impairment test, current and long-term forecasted financial results, changes in the discount rate between current and prior years, and operating strategy for each reporting unit. Based on the qualitative analysis performed in 2014, we concluded that there were no changes that were reasonably likely to cause the fair value of the reporting units to be less than the reporting units' carrying value and determined that there was no impairment of our goodwill. In the event we were to determine that a reporting unit's carrying value would more likely than not exceed its fair value, quantitative testing would be performed comparing carrying values to estimated fair values.
	For our intangible asset impairment testing, we use a discounted cash flow approach, based on a relief from royalty method (Level 3 measurement). This method assumes that, through ownership of trademarks and trade names, we avoid royalty expenses associated with licensing, resulting in cost savings. An estimated royalty rate, determined as a percentage of the related net sales, is used to estimate the value of the intangible assets. Based on the impairment tests of our intangible assets with indefinite lives performed in fourth quarter 2014, we determined that the fair value of our intangible assets exceeds their carrying value.
	See Note 11, Goodwill and Intangible Assets, for additional information.
Asset Retirement Obligations [Policy Text Block]	Asset Retirement Obligations
	We recognize our asset retirement obligations in the period in which they are incurred if sufficient information is available to reasonably estimate the fair value of the obligation. Fair value estimates are determined using Level 3 inputs in the fair value hierarchy. The fair values of our asset retirement obligations are measured using expected future cash outflows discounted using the company's credit-adjusted risk-free interest rate. When we record the liability, we capitalize the cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its settlement value, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, we will recognize a gain or loss for any difference between the settlement amount and the liability recorded.
Pension and Other Postretirement Benefits [Policy Text Block]	Pension Benefits
	Several estimates and assumptions are required to record pension costs and liabilities, including discount rates, expected return on plan assets, expected rate of compensation increases, retirement and mortality rates, expected contributions, and other factors. We review and update these assumptions annually unless a plan curtailment or other event occurs requiring that we update the estimates on an interim basis. See Note 7, Retirement and Benefit Plans, for additional information related to our pension plan. While we believe that the assumptions used to measure our pension obligations are reasonable, differences in actual experience or changes in assumptions may materially affect our pension obligations and future expense.
Long-Term Incentive Cash Plan [Policy Text Block]	Long-Term Incentive Cash Plan
	In 2012, key managers participated in a long-term incentive plan (LTIP) that pays awards in cash. The LTIP provided an annual award notice to participants granting them the opportunity to earn a cash award that was based on a target percentage of the participant's base salary and the company's achievement against corporate goals, both of which were set annually. Under the LTIP, the award, if any, is paid in three equal installments due no later than March 15 of the three years following the year the award was granted with continued employment as a precondition for receipt of each award installment. We recognize compensation expense based on the probability of the performance goals being met over the vesting period.
Deferred Software Costs [Policy Text Block]	Deferred Software Costs
	We defer internal-use software costs that benefit future years. These costs are amortized using the straight-line method over the expected life of the software, typically three to five years. "Other assets" in the Consolidated Balance Sheets includes $4.4 million and $3.7 million, respectively, of deferred software costs at December 31, 2014 and 2013.
Self-Insurance [Policy Text Block]	Self-Insurance
	We are self-insured for certain losses related to workers' compensation and medical claims as well as general and auto liability. The expected ultimate costs for claims incurred are recognized as liabilities in the Consolidated Balance Sheets and are estimated based principally on an analysis of historical claims data and estimates of claims incurred but not reported. Losses are accrued and charged to operations when it is probable that a loss has been incurred and the amount can be reasonably estimated. We maintain third-party stop-loss insurance policies to cover these liability costs in excess of predetermined retained amounts. Costs related to the administration of the plans and related claims are expensed as incurred.
New and Recently Adopted Accounting Standards [Policy Text Block]	New and Recently Adopted Accounting Standards
	In June 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-12, Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. This ASU requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. We adopted the provisions of this guidance on January 1, 2015, and it had no effect on our financial statements.
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. This ASU requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for annual and interim reporting periods beginning after December 15, 2016. Early adoption is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that this guidance will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our financial statements.
	There were no other accounting standards recently issued that had or are expected to have a material impact on our consolidated financial statements and associated disclosures.

	_______________________________________
	(a)	Equity and fixed-income securities represent common collective trusts managed by Russell Trust Company. The funds are valued at the net asset value (NAV) provided by Russell Trust Company, the administrator of the funds. The NAV is a practical expedient for fair value and is based on the value of the assets owned by the fund, less liabilities at year-end. While the underlying assets are actively traded on an exchange, the funds are not. We have the ability to redeem these equity and fixed-income securities with a one-day notice.
	(b)	Invested in the Russell Equity I Fund at December 31, 2014 and 2013. The fund seeks returns that exceed the Russell 1000 Index by investing in large-capitalization stocks of the U.S. stock market. In addition, at December 31, 2014 and 2013, our investments in this category included the Russell 1000 Index Fund, which seeks to track the investment results of an index composed of large- and mid-capitalization stocks of the U.S. stock market.
	(c)	Invested in the Russell Equity II Fund. The fund seeks returns that exceed the Russell 2500 Index by investing in the small- and mid-capitalization stocks of the U.S. stock market.
	(d)	Invested in the Russell International Fund with Active Currency at December 31, 2014 and 2013, which benchmarks against the Russell Developed ex-U.S. Large Cap Index Net and seeks favorable total returns and additional diversification through investment in non-U.S. equity securities and active currency management. The fund participates primarily in the stock markets of Europe and the Pacific Rim and seeks to opportunistically add value through active investment in foreign currencies. In addition, at December 31, 2014 and 2013, our investments in this category included the Russell Emerging Market Fund, which benchmarks against the Russell Emerging Markets Index and is designed to maintain a broadly diversified exposure to emerging market countries. At December 31, 2014 and 2013, investments in emerging markets represent approximately 23% and 20%, respectively, of our international portfolio.
	(e)	Invested in the Russell Multi-Manager Bond Fund at December 31, 2014 and 2013. The fund seeks to outperform the Barclays Capital U.S. Aggregate Bond Index over a full market cycle. The fund is designed to provide current income and, as a secondary objective, capital appreciation through a variety of diversified strategies, including sector rotation, modest interest rate timing, security selection, and tactical use of high-yield and emerging market bonds. In addition, at December 31, 2014, our investments in this category included the Russell Long Duration Fixed Income Fund, which is designed to provide maximum total return through diversified strategies including sector rotation, modest interest rate timing, security selection, and tactical use of high-yield, emerging market bonds and other non-index securities.
	(f)	The fund seeks to produce high risk-adjusted returns while targeting a low long-term average correlation to traditional markets. The fund invests internationally in a broad range of instruments, including, but not limited to, equities, currencies, convertible securities, futures, forwards, options, swaps, and other derivative products. The fair value of the hedge fund is estimated using the NAV of the investments as a practical expedient for fair value. We have the ability to redeem these investments at NAV within the near term, and they are thus classified within Level 2.
	(g)	Invested in the Russell Real Estate Equity Fund. Real estate investments include those in limited partnerships that invest in various domestic commercial and residential real estate projects. The fair values of real estate assets are typically determined by using income and/or cost approaches or a comparable sales approach, taking into consideration discount and capitalization rates, financial conditions, local market conditions, and the status of the capital markets, and they are thus classified within Level 3. Notwithstanding the above, the variety of valuation bases adopted and quality of management data of the underlying assets means that there are inherent difficulties in determining the value of the investments. Amounts realized on the sale of these investments may differ from the calculated values. We have the ability to redeem the real estate investments with a 110-calendar-day written notice prior to a quarterly trade date.
Expected Future Benefit Payments [Table Text Block]	The following benefit payments are expected to be paid to plan participants. Qualified pension benefit payments are paid from plan assets, while nonqualified pension benefit payments are paid by the company.

	(a)	Capital spending in 2013 for Wood Products includes $103.0 million for the acquisition of two plywood manufacturing facilities in the Carolinas. Capital spending in 2012 for Wood Products includes $2.4 million for the acquisition of a sawmill in Arden, Washington.
	(b)	EBITDA is defined as income (loss) before interest (interest expense and interest income), income taxes, and depreciation and amortization. EBITDA is the primary measure used by our chief operating decision maker to evaluate segment operating performance and to decide how to allocate resources to segments. We believe EBITDA is useful to investors because it provides a means to evaluate the operating performance of our segments and our company on an ongoing basis using criteria that are used by our internal decision makers and because it is frequently used by investors and other interested parties when comparing companies in our industry that have different financing and capital structures and/or tax rates. We believe EBITDA is a meaningful measure because it presents a transparent view of our recurring operating performance and allows management to readily view operating trends, perform analytical comparisons, and identify strategies to improve operating performance. EBITDA, however, is not a measure of our liquidity or financial performance under generally accepted accounting principles (GAAP) and should not be considered as an alternative to net income (loss), income (loss) from operations, or any other performance measure derived in accordance with GAAP or as an alternative to cash flow from operating activities as a measure of our liquidity. The use of EBITDA instead of net income (loss) or segment income (loss) has limitations as an analytical tool, including the inability to determine profitability; the exclusion of interest expense, interest income, and associated significant cash requirements; and the exclusion of depreciation and amortization, which represent unavoidable operating costs. Management compensates for the limitations of EBITDA by relying on our GAAP results. Our measure of EBITDA is not necessarily comparable to other similarly titled captions of other companies due to potential inconsistencies in the methods of calculation.

[1]	Benefits paid during the year ended December 31, 2014 includes approximately $15 million of lump-sum cash payments to certain terminated and vested participants in settlement of pension obligations.
[2]	Represents amounts reclassified from accumulated other comprehensive loss. These amounts are included in the computation of net periodic pension cost. For additional information, see Note 7, Retirement and Benefit Plans.
[3]	Pension benefits for all salaried employees are frozen, resulting in an assumption for the rate of compensation increase of zero. In addition to the salaried benefits being frozen, there are currently no scheduled increases in pension benefit rates applicable to past service covering hourly employees who continue to accrue benefits.
[4]	Invested in the Russell EquityB I Fund at December 31, 2014 and 2013. The fund seeks returns that exceed the Russell 1000 Index by investing in large-capitalization stocks of the U.S. stock market. In addition, at December 31, 2014 and 2013, our investments in this category included the Russell 1000 Index Fund, which seeks to track the investment results of an index composed of large- and mid-capitalization stocks of the U.S. stock market.
[5]	Invested in the Russell EquityB II Fund. The fund seeks returns that exceed the Russell 2500 Index by investing in the small- and mid-capitalization stocks of the U.S. stock market.
[6]	Invested in the Russell International Fund with Active Currency at DecemberB 31, 2014 and 2013, which benchmarks against the Russell Developed ex-U.S. Large Cap Index Net and seeks favorable total returns and additional diversification through investment in non-U.S. equity securities and active currency management. The fund participates primarily in the stock markets of Europe and the Pacific Rim and seeks to opportunistically add value through active investment in foreign currencies. In addition, at DecemberB 31, 2014 and 2013, our investments in this category included the Russell Emerging Market Fund, which benchmarks against the Russell Emerging Markets Index and is designed to maintain a broadly diversified exposure to emerging market countries. At December 31, 2014 and 2013, investments in emerging markets represent approximately 23% and 20%, respectively, of our international portfolio.
[7]	Invested in the Russell Multi-Manager Bond Fund at DecemberB 31, 2014 and 2013. The fund seeks to outperform the Barclays Capital U.S. Aggregate Bond Index over a full market cycle. The fund is designed to provide current income and, as a secondary objective, capital appreciation through a variety of diversified strategies, including sector rotation, modest interest rate timing, security selection, and tactical use of high-yield and emerging market bonds. In addition, at December 31, 2014, our investments in this category included the Russell Long Duration Fixed Income Fund, which is designed to provide maximum total return through diversified strategies including sector rotation, modest interest rate timing, security selection, and tactical use of high-yield, emerging market bonds and other non-index securities.
[8]	The fund seeks to produce high risk-adjusted returns while targeting a low long-term average correlation to traditional markets. The fund invests internationally in a broad range of instruments, including, but not limited to, equities, currencies, convertible securities, futures, forwards, options, swaps, and other derivative products. The fair value of the hedge fund is estimated using the NAV of the investments as a practical expedient for fair value. We have the ability to redeem these investments at NAV within the near term, and they are thus classified within Level 2.
[9]	Invested in the Russell Real Estate Equity Fund. Real estate investments include those in limited partnerships that invest in various domestic commercial and residential real estate projects. The fair values of real estate assets are typically determined by using income and/or cost approaches or a comparable sales approach, taking into consideration discount and capitalization rates, financial conditions, local market conditions, and the status of the capital markets, and they are thus classified within Level 3. Notwithstanding the above, the variety of valuation bases adopted and quality of management data of the underlying assets means that there are inherent difficulties in determining the value of the investments. Amounts realized on the sale of these investments may differ from the calculated values. We have the ability to redeem the real estate investments with a 110-calendar-day written notice prior to a quarterly trade date.

The fund is designed to provide current income and, as a secondary objective, capital appreciation through a variety of diversified strategies, including sector rotation, modest interest rate timing, security selection, and tactical use of high-yield and emerging market bonds. In addition, at December 31, 2014, our investments in this category included the Russell Long Duration Fixed Income Fund, which is designed to provide maximum total return through diversified strategies including sector rotation, modest interest rate timing, security selection, and tactical use of high-yield, emerging market bonds and other non-index securities.
[5]	The fund seeks to produce high risk-adjusted returns while targeting a low long-term average correlation to traditional markets. The fund invests internationally in a broad range of instruments, including, but not limited to, equities, currencies, convertible securities, futures, forwards, options, swaps, and other derivative products. The fair value of the hedge fund is estimated using the NAV of the investments as a practical expedient for fair value. We have the ability to redeem these investments at NAV within the near term, and they are thus classified within Level 2.
[6]	Invested in the Russell Real Estate Equity Fund. Real estate investments include those in limited partnerships that invest in various domestic commercial and residential real estate projects. The fair values of real estate assets are typically determined by using income and/or cost approaches or a comparable sales approach, taking into consideration discount and capitalization rates, financial conditions, local market conditions, and the status of the capital markets, and they are thus classified within Level 3. Notwithstanding the above, the variety of valuation bases adopted and quality of management data of the underlying assets means that there are inherent difficulties in determining the value of the investments. Amounts realized on the sale of these investments may differ from the calculated values. We have the ability to redeem the real estate investments with a 110-calendar-day written notice prior to a quarterly trade date.
[7]	Equity and fixed-income securities represent common collective trusts managed by Russell Trust Company. The funds are valued at the net asset value (NAV) provided by Russell Trust Company, the administrator of the funds. The NAV is a practical expedient for fair value and is based on the value of the assets owned by the fund, less liabilities at year-end. While the underlying assets are actively traded on an exchange, the funds are not. We have the ability to redeem these equity and fixed-income securities with a one-day notice.

[2]	EBITDA is defined as income (loss) before interest (interest expense and interest income), income taxes, and depreciation and amortization. EBITDA is the primary measure used by our chief operating decision maker to evaluate segment operating performance and to decide how to allocate resources to segments. We believe EBITDA is useful to investors because it provides a means to evaluate the operating performance of our segments and our company on an ongoing basis using criteria that are used by our internal decision makers and because it is frequently used by investors and other interested parties when comparing companies in our industry that have different financing and capital structures and/or tax rates. We believe EBITDA is a meaningful measure because it presents a transparent view of our recurring operating performance and allows management to readily view operating trends, perform analytical comparisons, and identify strategies to improve operating performance. EBITDA, however, is not a measure of our liquidity or financial performance under generally accepted accounting principles (GAAP) and should not be considered as an alternative to net income (loss), income (loss) from operations, or any other performance measure derived in accordance with GAAP or as an alternative to cash flow from operating activities as a measure of our liquidity. The use of EBITDA instead of net income (loss) or segment income (loss) has limitations as an analytical tool, including the inability to determine profitability; the exclusion of interest expense, interest income, and associated significant cash requirements; and the exclusion of depreciation and amortization, which represent unavoidable operating costs. Management compensates for the limitations of EBITDA by relying on our GAAP results. Our measure of EBITDA is not necessarily comparable to other similarly titled captions of other companies due to potential inconsistencies in the methods of calculation.The following is a reconciliation of net income to EBITDA for the consolidated company: Year Ended December 31 2014B 2013B 2012 (millions)Net income (1)B $80.0B $116.9B $41.5Interest expenseB 22.0B 20.4B 21.8Interest incomeB (0.2)B (0.2)B (0.4)Income tax provision (benefit) (1)B 43.3B (38.8)B 0.3Depreciation and amortizationB 51.4B 38.0B 33.4EBITDAB $196.6B $136.4B $96.6 _______________________________________B (1)The year ended DecemberB 31, 2013, includes a $68.7 million income tax benefit associated with the recording of net deferred tax assets upon our conversion to a corporation.
