Nature of Operations and Basis

Nature of Operations and Basis of Presentation	6 Months Ended

Accounting Policies [Abstract]
Nature of Operations and Basis of Presentation	Nature of Operations and Basis of Presentation GENERAL Clearwater Paper manufactures quality consumer tissue, away-from-home tissue, parent roll tissue, bleached paperboard and pulp at manufacturing facilities across the nation. The company is a premier supplier of private label tissue to major retailers and wholesale distributors, including grocery, drug, mass merchants and discount stores. In addition, the company produces bleached paperboard used by quality-conscious printers and packaging converters, and offers services that include custom sheeting, slitting and cutting. Clearwater Paper's employees build shareholder value by developing strong customer relationships through quality and service. In the second half of 2017, we began a review of our selling, general and administrative cost structure as part of our effort to maintain our longer-term competitiveness. As a result of this review, in the fourth quarter of 2017 we began executing on a plan that is expected to result in lower selling, general and administrative expenses beginning in 2018. For the six months ended June 30, 2018 , we incurred $6.2 million of expenses associated with these efforts, which consisted primarily of severance and professional services expenses. On March 31, 2017, we closed our Oklahoma City, Oklahoma facility. In the first half of 2017, we incurred $6.0 million of costs associated with this closure, which included $3.7 million in accelerated depreciation. FINANCIAL STATEMENT PREPARATION AND PRESENTATION The accompanying Consolidated Balance Sheets at June 30, 2018 and December 31, 2017 , the related Consolidated Statements of Operations, and Comprehensive Income for the three and six months ended June 30, 2018 and 2017, and Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2018 and 2017 , have been prepared in conformity with accounting principles generally accepted in the United States of America, or GAAP. We believe that all adjustments necessary for a fair presentation of the results of the interim periods presented have been included. The results of operations for any interim period are not necessarily indicative of the results of operations to be expected for the full year. This Quarterly Report on Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2017 , as filed with the Securities and Exchange Commission, or SEC, on February 21, 2018 . SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES SIGNIFICANT ESTIMATES The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting periods. Significant areas that may require the use of estimates and measurement of uncertainty include determination of net realizable value for deferred tax assets, uncertain tax positions, assessment of impairment of long-lived assets, variable consideration or reductions to revenue, revenue recognition estimates related to allocating the transaction price to various performance obligations, goodwill and intangibles, assessment of environmental matters, equity-based compensation and pension and postretirement obligation assumptions. Actual results could differ from those estimates and assumptions. CASH AND CASH EQUIVALENTS We consider all highly liquid instruments with maturities of three months or less at date of purchase to be cash equivalents. PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment are stated at cost, including any interest costs capitalized, less accumulated depreciation. Depreciation of buildings, equipment and other depreciable assets is determined using the straight-line method. Assets we acquire through business combinations have estimated lives that are typically shorter than the assets we construct or buy new. Accumulated depreciation totaled $1,678.6 million and $1,636.3 million at June 30, 2018 and December 31, 2017 , respectively. For the six months ended June 30, 2018 , we capitalized $2.6 million of interest expense associated with the construction of a paper machine at our Shelby, North Carolina consumer products facility and $0.6 million of interest expense associated with the construction of a continuous pulp digester at our Lewiston, Idaho pulp and paperboard facility. For the six months ended June 30, 2017, we capitalized $1.8 million of interest expense associated with the continuous pulp digester project and $0.2 million associated with the Shelby paper machine. Consistent with authoritative guidance, we assess the carrying amount of long-lived assets with definite lives that are held-for-use and evaluate them for recoverability whenever events or changes in circumstances indicate that we may be unable to recover the carrying amount of the assets. REVENUE RECOGNITION We enter into contracts that can include various combinations of tissue and paperboard products, which are generally capable of being distinct and accounted for as separate performance obligations. Revenue is recognized at a point in time upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. Transfer of control typically occurs when the title and risk of loss passes to the customer. Shipping terms generally indicate when title and the risk of loss have passed. Revenue is recognized at shipment for sales when shipping terms are free on board, or FOB, shipping point. For sales where shipping terms are FOB destination, revenue is recognized when the goods are received by the customer. Revenue from both domestic and foreign sales of our products can involve shipping terms of either FOB shipping point or FOB destination or other shipping terms, depending upon the sales agreement with the customer. We have elected to treat shipping and handling costs for FOB shipping point contracts as a fulfillment cost, not as a separate performance obligation. No revenue is recognized over time. We typically expense incremental direct costs of obtaining a contract (sales commissions) when incurred because the amortization period is generally 12 months or less. We have also elected to use the practical expedient to not disclose unsatisfied or partially satisfied performance obligations as we have no unsatisfied contracts where the remaining portions are expected to be satisfied in a period greater than one year. We provide for trade promotions, customer cash discounts, customer returns and other deductions as reductions to net sales, which are accounted for as variable consideration when estimating the amount of revenue to recognize . Returns and credits are estimated at contract inception and updated at the end of each reporting period as additional information becomes available. Revenue net of returns and credits is only recognized to the extent that it is probable that a significant reversal of any incremental revenue will not occur. Significant judgment is required to determine the most probable amount of variable consideration to apply as a reduction to net sales. Revenue is recognized net of any taxes collected from customers, which are subsequently remitted to governmental authorities. Payment terms and conditions vary by contract type. Terms generally include a requirement of payment within 30 days, and do not include a significant financing component. Trade accounts receivable are stated at the amount we expect to collect. Trade accounts receivable do not bear interest. The allowance for doubtful accounts is our best estimate of the losses we expect will result from the inability of our customers to make required payments. We generally determine the allowance based on a combination of actual historical write-off experience and an analysis of specific customer accounts. As of June 30, 2018 and December 31, 2017 , we had allowances for doubtful accounts of $ 1.3 million and $1.4 million , respectively. Refer to Note 15, "Segment Information," for further information, including the disaggregation of revenue by segment, primary geographical market, and major product type. ACCOUNT PURCHASE AGREEMENT In June 2018, we entered into an agreement (the “Account Purchase Agreement”) to offer to sell, on a revolving and discounted basis, certain trade accounts receivable balances to an unrelated third-party financial institution. If the financial institution purchases receivables thereunder, in its sole discretion, such transfers are accounted for as sales of receivables resulting in the receivables being de-recognized from our Consolidated Balance Sheet. The Account Purchase Agreement provides for the continuing sale of certain receivables on a revolving basis until June 2020 and automatically renews for successive one year terms, unless either party elects to terminate the Account Purchase Agreement in accordance with its terms. The maximum amount of receivables that may be sold at any time, prior to the settlement thereof, is $60.0 million . For the quarter ended June 30, 2018, $22.0 million of receivables had been sold under the Account Purchase Agreement. The proceeds from these sales of receivables are included within the change in receivables in the operating activities section of the Condensed Consolidated Statements of Cash Flows. The recorded factoring expense on sale of receivables is less than $0.1 million for the quarter ended June 30, 2018 and is included in the "Selling, general and administrative expenses" line in the Consolidated Statement of Operations. We have no retained interest in the receivables sold under the Account Purchase Agreement, however, we do have collection and administrative responsibilities for the sold receivables. The fair value of the servicing arrangement was not material to the financial statements. STOCKHOLDERS’ EQUITY On December 15, 2015, we announced that our Board of Directors had approved a stock repurchase program authorizing the repurchase of up to $100 million of our common stock. The repurchase program authorizes purchases of our common stock from time to time through open market purchases, negotiated transactions or other means, including accelerated stock repurchases and 10b5-1 trading plans in accordance with applicable securities laws and other restrictions. We have no obligation to repurchase stock under this program and may suspend or terminate the program at any time. In total, we have repurchased 1,440,696 shares of our outstanding common stock pursuant to this repurchase program, of which 84,750 shares were repurchased during the first half of 2017 at an average price of $57.53 per share. We did not repurchase shares during the first half of 2018. As of June 30, 2018 , we had up to $29.8 million of authorization remaining pursuant to this stock repurchase program. DERIVATIVES We had no activity during the three and six months ended June 30, 2018 and 2017 that required hedge or derivative accounting treatment. To help mitigate our exposure to market risk for changes in utility commodity pricing, we use firm price contracts to supply a portion of the natural gas requirements for our manufacturing facilities. As of June 30, 2018 , these contracts covered approximately 29% of our expected average monthly natural gas requirements for the remainder of 2018 . Historically, these contracts have qualified for treatment as “normal purchases or normal sales” under authoritative guidance and thus required no mark-to-market adjustment.

Recently Adopted and New Accoun

Recently Adopted and New Accounting Standards	6 Months Ended

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Adopted and New Accounting Standards	Recently Adopted and New Accounting Standards Recently Adopted In February 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income to allow for reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (Act). This ASU also requires certain disclosures about stranded tax effects. We adopted this standard on January 1, 2018, which resulted in the reclassification of $12.9 million between retained earnings and accumulated other comprehensive loss (AOCL), increasing retained earnings and AOCL within the equity section of our Consolidated Balance Sheet. In May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting to clarify when to account for a change to the terms or conditions of a share-based payment award as a modification. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions. The ASU was effective prospectively for annual periods beginning after December 15, 2017, including interim periods within those annual periods. We adopted this standard on January 1, 2018. The adoption of this ASU did not have a material impact on our consolidated financial statements. In March 2017, the FASB issued ASU 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost . The standard requires that an employer disaggregate the service cost component, presented within the "Cost of sales" and "Selling, general, and administrative" line items on our Consolidated Statements of Operations, from the other components of net periodic cost (benefit), which are now presented within the "Non-operating pension and other postretirement benefit (costs) income" line item in our Consolidated Statements of Operations. We adopted the standard effective January 1, 2018, which resulted in the retrospective presentation in the income statement of the disaggregated components and the prospective changes to the capitalized portion of both service cost and the other components within inventory. The adoption did not have a material impact on our consolidated financial statements. Refer to Note 10, "Pension and Other Postretirement Employee Benefit Plans," for further information, including the amounts associated with the reclassification of the components of net periodic cost as operating and non-operating. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) . The core principle of the new standard is for companies to recognize revenue in a manner that depicts the transfer of goods or services to customers in amounts that reflect the consideration, or payment, to which the company expects to be entitled in exchange for those goods or services. The standard requires enhanced disclosures about revenue, including revenue recognition policies to identify performance obligations to customers and significant judgments in measurement and recognition. We adopted the new revenue guidance effective January 1, 2018 using the cumulative effect method, and did not have an adjustment to retained earnings upon adoption. The standard was applied to open contracts at the date of initial application. Aside from expanded disclosures, the adoption of Topic 606 did not have a material impact on our consolidated financial statement line items, processes, or internal controls. Refer to Note 1, "Nature of Operations and Basis of Presentation," for information about the basis of revenue recognition, and Note 15, "Segment Information," for further information including the disaggregation of revenue by segment, primary geographical market, and major product type. New Accounting Standards In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) . The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We expect the adoption of this ASU will increase both our assets and liabilities presented on our Consolidated Balance Sheets to reflect the ROU assets and corresponding lease liabilities, as well as increase our leasing disclosures. As of December 31, 2017, the total future minimum lease payments for our operating leases totaled $75.3 million . We plan to adopt this standard on January 1, 2019. We are continuing our assessment and review of existing leases, implementing a leasing software solution, and addressing necessary policy and process changes in preparation for adoption. We reviewed all other new accounting pronouncements issued in the period and concluded that they are not applicable to our business.

For the six months ended June 30, 2018 and 2017 , intangible assets amortization expense was $3.9 million and $4.0 million , respectively. Goodwill is not amortized but is reviewed for impairment annually as of November 1 and at any time when events indicate impairment may have occurred. During the quarter ended June 30, 2018, we identified indicators of possible goodwill impairment for our Consumer Products reporting unit, namely the decline in actual results compared to the forecast used as part of our annual goodwill assessment performed in the fourth quarter of 2017, as well as a decline in our stock price. As a result, we performed a qualitative assessment and determined that it was more likely than not that the fair value of the reporting unit was greater than its carrying amount. Therefore, there was no impairment of goodwill as of June 30, 2018.

Taxes

Income Tax Disclosure [Abstract]
Taxes	Income Taxes Consistent with authoritative guidance, our estimated annual effective tax rate is used to allocate expected annual income tax expense to interim periods. The rate is the ratio of estimated annual income tax expense to estimated pre-tax ordinary income, and excludes "discrete items," which are significant, unusual or infrequent items reported separately net of their related tax effect. The estimated annual effective tax rate is applied to the current interim period's ordinary income to determine the income tax expense allocated to the interim period. The income tax effects of discrete items are then determined separately and recognized in the interim period in which the income or expense items arise. Our estimated annual effective tax rate applied to the second quarter of 2018 is approximately 26% , compared with approximately 33% for the comparable interim period in 2017. The decrease in the rate is primarily due to the rate reduction enacted with the Tax Cuts and Jobs Act.

Earnings Per Share [Abstract]
Earnings per Common Share	Earnings per Common Share Basic earnings per share are based on the weighted average number of shares of common stock outstanding. Diluted earnings per share are based upon the weighted average number of shares of common stock outstanding plus all potentially dilutive securities that were assumed to be converted into common shares at the beginning of the period under the treasury stock method. The following table reconciles the number of common shares used in calculating the basic and diluted net earnings per share: Three Months Ended June 30, Six Months Ended June 30, 2018 2017 2018 2017 Basic weighted-average common shares outstanding 1 16,486,935 16,457,196 16,491,366 16,470,525 Incremental shares due to: Restricted stock units 20,970 37,703 29,530 35,922 Performance shares 47,266 78,351 52,051 74,975 Stock options — 16,868 90 30,636 Diluted weighted-average common shares outstanding 16,555,171 16,590,118 16,573,037 16,612,058 Basic net earnings per common share $ 0.42 $ 0.49 $ 0.58 $ 0.94 Diluted net earnings per common share 0.42 0.48 0.58 0.94 Anti-dilutive shares excluded from calculation 1,029,983 515,322 912,863 493,150 1 Basic average common shares outstanding include restricted stock awards that are fully vested, but are deferred for future issuance.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Equity-Based Compensation	Equity-Based Compensation We recognize equity-based compensation expense for all equity-based payment awards made to employees and directors, including restricted stock units, or RSUs, performance shares and stock options, based on estimated fair values. EMPLOYEE AWARDS Employee equity-based compensation expense was recognized as follows: Three Months Ended June 30, Six Months Ended June 30, (In thousands) 2018 2017 2018 2017 Restricted stock units $ 582 $ 503 $ 1,004 $ 795 Performance shares 377 630 910 1,226 Stock options 593 736 1,128 1,315 Total employee equity-based compensation expense $ 1,552 $ 1,869 $ 3,042 $ 3,336 As provided in the Clearwater Paper Corporation 2008 and 2017 Stock Incentive Plans, the following performance measures are used to determine the number of performance shares ultimately issuable: • For performance shares granted in 2017, the performance measure used for 40% of the grant is a comparison of the percentile ranking of our total stockholder return, or TSR, compared to the TSR of a selected index, and for 60% of the performance share awards granted the performance measure used is a return on invested capital, or ROIC, performance measure. • For performance shares granted in 2018, the performance measure used for 40% of the performance share awards granted is an ROIC performance measure. For the remaining 60% of the grants, a free cash flow performance measure is used. The combined performance of these measures is then subject to an adjustment (increase or decrease) of up to 25% based on our TSR compared to the TSR performance of a selected index. The number of performance shares actually issued, as a percentage of the amount subject to the performance share award, could range from 0% - 200% . During the first six months of 2018 , 19,133 RSUs were settled and distributed. After adjusting for minimum tax withholdings, a net 13,221 shares were issued. In connection with the issued RSUs, the minimum tax withholding payments made during the six months ended June 30, 2018 totaled $0.2 million . During the six months ended June 30, 2018 , we had 4,731 stock option awards expire with a weighted-average exercise price of $ 64.31 . At June 30, 2018 , we had 300,021 stock option awards that were exercisable with a weighted-average exercise price of $63.18 . The following table summarizes the number of share-based awards granted under the Clearwater Paper Corporation 2017 Stock Incentive Plan during the six months ended June 30, 2018 and the grant-date fair value of the awards: Six Months Ended June 30, 2018 Number of Average Fair Restricted stock units 108,816 $ 37.45 Performance shares 49,040 37.45 Stock options 196,488 14.51 DIRECTOR AWARDS Annually, each outside member of our Board of Directors receives deferred equity-based awards that are measured in units of our common stock and ultimately settled in cash at the time of payment. Accordingly, the compensation expense associated with these awards is subject to fluctuations each quarter based on mark-to-market adjustments at each reporting period in line with changes in the market price of our common stock. As a result of the mark-to-market adjustment, we recorded director equity-based compensation benefit of $2.0 million and $1.5 million for the three months ended June 30, 2018 and 2017 , respectively. For the six months ended June 30, 2018 and 2017 , we recorded director equity-based compensation benefit of $2.7 million and $2.9 million , respectively. As of June 30, 2018 , the liability amounts associated with director equity-based compensation included in "Other long-term obligations" and "Accounts payable and accrued liabilities" on the accompanying Consolidated Balance Sheet were $0.8 million and $1.2 million , respectively. At December 31, 2017 , the liability amounts associated with director equity-based compensation included in "Other long-term obligations" and "Accounts payable and accrued liabilities" totaled $3.6 million and $2.4 million , respectively.

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities, or “Level 1” measurements, followed by quoted prices of similar assets or observable market data considering the assets' underlying maturities, or “Level 2” measurements, and the lowest priority to unobservable inputs, or “Level 3” measurements. The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used should seek to maximize the use of observable inputs and minimize the use of unobservable inputs. Cash and cash equivalents, borrowings under the revolving credit facilities and long-term debt are the only items measured at fair value on a recurring basis. We do not have any financial assets measured at fair value on a nonrecurring basis. Nonfinancial assets measured at fair value on a nonrecurring basis include items such as long-lived assets held and used that are measured at fair value resulting from impairment, if deemed necessary.

Nature of Operations and Basi24

Nature of Operations and Basis of Presentation (Policies)	6 Months Ended
	Jun. 30, 2018
Account Purchase Agreement [Line Items]
Account Purchase Agreement [Table Text Block]	ACCOUNT PURCHASE AGREEMENT In June 2018, we entered into an agreement (the “Account Purchase Agreement”) to offer to sell, on a revolving and discounted basis, certain trade accounts receivable balances to an unrelated third-party financial institution. If the financial institution purchases receivables thereunder, in its sole discretion, such transfers are accounted for as sales of receivables resulting in the receivables being de-recognized from our Consolidated Balance Sheet. The Account Purchase Agreement provides for the continuing sale of certain receivables on a revolving basis until June 2020 and automatically renews for successive one year terms, unless either party elects to terminate the Account Purchase Agreement in accordance with its terms. The maximum amount of receivables that may be sold at any time, prior to the settlement thereof, is $60.0 million . For the quarter ended June 30, 2018, $22.0 million of receivables had been sold under the Account Purchase Agreement. The proceeds from these sales of receivables are included within the change in receivables in the operating activities section of the Condensed Consolidated Statements of Cash Flows. The recorded factoring expense on sale of receivables is less than $0.1 million for the quarter ended June 30, 2018 and is included in the "Selling, general and administrative expenses" line in the Consolidated Statement of Operations. We have no retained interest in the receivables sold under the Account Purchase Agreement, however, we do have collection and administrative responsibilities for the sold receivables. The fair value of the servicing arrangement was not material to the financial statements.
SIGNIFICANT ESTIMATES	SIGNIFICANT ESTIMATES The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting periods. Significant areas that may require the use of estimates and measurement of uncertainty include determination of net realizable value for deferred tax assets, uncertain tax positions, assessment of impairment of long-lived assets, variable consideration or reductions to revenue, revenue recognition estimates related to allocating the transaction price to various performance obligations, goodwill and intangibles, assessment of environmental matters, equity-based compensation and pension and postretirement obligation assumptions. Actual results could differ from those estimates and assumptions.
RESTRICTED CASH AND SHORT-TERM INVESTMENTS	CASH AND CASH EQUIVALENTS We consider all highly liquid instruments with maturities of three months or less at date of purchase to be cash equivalents.
TRADE ACCOUNTS RECEIVABLE	REVENUE RECOGNITION We enter into contracts that can include various combinations of tissue and paperboard products, which are generally capable of being distinct and accounted for as separate performance obligations. Revenue is recognized at a point in time upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. Transfer of control typically occurs when the title and risk of loss passes to the customer. Shipping terms generally indicate when title and the risk of loss have passed. Revenue is recognized at shipment for sales when shipping terms are free on board, or FOB, shipping point. For sales where shipping terms are FOB destination, revenue is recognized when the goods are received by the customer. Revenue from both domestic and foreign sales of our products can involve shipping terms of either FOB shipping point or FOB destination or other shipping terms, depending upon the sales agreement with the customer. We have elected to treat shipping and handling costs for FOB shipping point contracts as a fulfillment cost, not as a separate performance obligation. No revenue is recognized over time. We typically expense incremental direct costs of obtaining a contract (sales commissions) when incurred because the amortization period is generally 12 months or less. We have also elected to use the practical expedient to not disclose unsatisfied or partially satisfied performance obligations as we have no unsatisfied contracts where the remaining portions are expected to be satisfied in a period greater than one year. We provide for trade promotions, customer cash discounts, customer returns and other deductions as reductions to net sales, which are accounted for as variable consideration when estimating the amount of revenue to recognize . Returns and credits are estimated at contract inception and updated at the end of each reporting period as additional information becomes available. Revenue net of returns and credits is only recognized to the extent that it is probable that a significant reversal of any incremental revenue will not occur. Significant judgment is required to determine the most probable amount of variable consideration to apply as a reduction to net sales. Revenue is recognized net of any taxes collected from customers, which are subsequently remitted to governmental authorities. Payment terms and conditions vary by contract type. Terms generally include a requirement of payment within 30 days, and do not include a significant financing component. Trade accounts receivable are stated at the amount we expect to collect. Trade accounts receivable do not bear interest. The allowance for doubtful accounts is our best estimate of the losses we expect will result from the inability of our customers to make required payments. We generally determine the allowance based on a combination of actual historical write-off experience and an analysis of specific customer accounts. As of June 30, 2018 and December 31, 2017 , we had allowances for doubtful accounts of $ 1.3 million and $1.4 million , respectively. Refer to Note 15, "Segment Information," for further information, including the disaggregation of revenue by segment, primary geographical market, and major product type.
PROPERTY, PLANT AND EQUIPMENT	PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment are stated at cost, including any interest costs capitalized, less accumulated depreciation. Depreciation of buildings, equipment and other depreciable assets is determined using the straight-line method. Assets we acquire through business combinations have estimated lives that are typically shorter than the assets we construct or buy new. Accumulated depreciation totaled $1,678.6 million and $1,636.3 million at June 30, 2018 and December 31, 2017 , respectively. For the six months ended June 30, 2018 , we capitalized $2.6 million of interest expense associated with the construction of a paper machine at our Shelby, North Carolina consumer products facility and $0.6 million of interest expense associated with the construction of a continuous pulp digester at our Lewiston, Idaho pulp and paperboard facility. For the six months ended June 30, 2017, we capitalized $1.8 million of interest expense associated with the continuous pulp digester project and $0.2 million associated with the Shelby paper machine. Consistent with authoritative guidance, we assess the carrying amount of long-lived assets with definite lives that are held-for-use and evaluate them for recoverability whenever events or changes in circumstances indicate that we may be unable to recover the carrying amount of the assets.
STOCKHOLDERS' EQUITY	STOCKHOLDERS’ EQUITY On December 15, 2015, we announced that our Board of Directors had approved a stock repurchase program authorizing the repurchase of up to $100 million of our common stock. The repurchase program authorizes purchases of our common stock from time to time through open market purchases, negotiated transactions or other means, including accelerated stock repurchases and 10b5-1 trading plans in accordance with applicable securities laws and other restrictions. We have no obligation to repurchase stock under this program and may suspend or terminate the program at any time. In total, we have repurchased 1,440,696 shares of our outstanding common stock pursuant to this repurchase program, of which 84,750 shares were repurchased during the first half of 2017 at an average price of $57.53 per share. We did not repurchase shares during the first half of 2018. As of June 30, 2018 , we had up to $29.8 million of authorization remaining pursuant to this stock repurchase program.
DERIVATIVES	DERIVATIVES We had no activity during the three and six months ended June 30, 2018 and 2017 that required hedge or derivative accounting treatment. To help mitigate our exposure to market risk for changes in utility commodity pricing, we use firm price contracts to supply a portion of the natural gas requirements for our manufacturing facilities. As of June 30, 2018 , these contracts covered approximately 29% of our expected average monthly natural gas requirements for the remainder of 2018 . Historically, these contracts have qualified for treatment as “normal purchases or normal sales” under authoritative guidance and thus required no mark-to-market adjustment.

Account Purchase Agreement [Table Text Block]			ACCOUNT PURCHASE AGREEMENT In June 2018, we entered into an agreement (the “Account Purchase Agreement”) to offer to sell, on a revolving and discounted basis, certain trade accounts receivable balances to an unrelated third-party financial institution. If the financial institution purchases receivables thereunder, in its sole discretion, such transfers are accounted for as sales of receivables resulting in the receivables being de-recognized from our Consolidated Balance Sheet. The Account Purchase Agreement provides for the continuing sale of certain receivables on a revolving basis until June 2020 and automatically renews for successive one year terms, unless either party elects to terminate the Account Purchase Agreement in accordance with its terms. The maximum amount of receivables that may be sold at any time, prior to the settlement thereof, is $60.0 million . For the quarter ended June 30, 2018, $22.0 million of receivables had been sold under the Account Purchase Agreement. The proceeds from these sales of receivables are included within the change in receivables in the operating activities section of the Condensed Consolidated Statements of Cash Flows. The recorded factoring expense on sale of receivables is less than $0.1 million for the quarter ended June 30, 2018 and is included in the "Selling, general and administrative expenses" line in the Consolidated Statement of Operations. We have no retained interest in the receivables sold under the Account Purchase Agreement, however, we do have collection and administrative responsibilities for the sold receivables. The fair value of the servicing arrangement was not material to the financial statements.
