[1]	For the nine months ended September 30, 2016 and 2015, net periodic costs associated with our pension and other postretirement employee benefit, or OPEB, plans included in other comprehensive income and reclassified from accumulated other comprehensive loss included $2.8 million and $9.5 million, respectively, of actuarial loss amortization, as well as $1.3 million and $1.6 million, respectively, of prior service credit amortization, all net of tax totaling $0.6 million and $3.1 million, respectively. These accumulated other comprehensive loss components are included in the computation of net periodic pension and OPEB costs in Note 10, “Pension and Other Postretirement Employee Benefit Plans.” 2 Included in "Amounts reclassified from accumulated other comprehensive loss" above for the nine months ended September 30, 2016 is settlement expense of $3.5 million associated with the remeasurement of our salaried pension plan, which is discussed further in Note 10, “Pension and Other Postretirement Employee Benefit Plans.” The remeasurement resulted in a settlement loss of $0.8 million recorded to the pension liability and reclassified from accumulated other comprehensive loss. The settlement expense and corresponding remeasurement are net of tax totaling $1.1 million.

Nature of Operations and Basis of Presentation	Sep. 30, 2016
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. In the third quarter of 2016, an indemnity escrow account established in connection with the December 2014 sale of our former specialty business and mills was settled, resulting in the release of $2.3 million from a restricted cash escrow account. We recorded a net $1.8 million gain in "Selling, general and administrative expenses" in our Consolidated Statement of Operations for the three and nine months ended September 30, 2016, which included the release of the escrow account less $0.5 million of other settlement related costs. FINANCIAL STATEMENT PREPARATION AND PRESENTATION The accompanying Consolidated Balance Sheets at September 30, 2016 and December 31, 2015 , the related Consolidated Statements of Operations and Comprehensive Income for the three and nine months ended September 30, 2016 and 2015 , and the Consolidated Statements of Cash Flows for the nine months ended September 30, 2016 and 2015 , 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 statement 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, 2015 , as filed with the Securities and Exchange Commission, or SEC, on February 22, 2016 . 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 requiring 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, 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 to be cash equivalents. SHORT-TERM INVESTMENTS AND RESTRICTED CASH Our short-term investments are invested primarily in demand deposits, which have very short maturity periods, and therefore earn an interest rate commensurate with low-risk instruments. Our restricted cash in which the underlying instrument has a term of greater than twelve months from the balance sheet date is classified as non-current and is included in “Other assets, net” on our Consolidated Balance Sheet. As discussed above, the indemnity escrow related to the sale of our former specialty business and mills was settled during the three months ended September 30, 2016 . Consequently, the $2.3 million restricted cash escrow account, reflected in "Restricted cash" on our Consolidated Balance Sheet at December 31, 2015, was released during the third quarter of 2016, and we had no restricted cash on our Consolidated Balance Sheet at September 30, 2016 . TRADE ACCOUNTS RECEIVABLE 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 September 30, 2016 and December 31, 2015 , we had allowances for doubtful accounts of $1.3 million and $1.4 million , respectively. 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 $1,571.9 million and $1,512.1 million at September 30, 2016 and December 31, 2015 , respectively. For the three and nine months ended September 30, 2016 , we capitalized $0.7 million and $1.6 million , respectively, of interest expense associated with the construction of a continuous pulp digester at our Lewiston, Idaho pulp and paperboard facility. For the three and nine months ended September 30, 2015, we capitalized $0.1 million and $0.2 million , respectively, of interest expense associated with this project. 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 On December 15, 2015, we announced that our Board of Directors had approved a new 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 1,098,568 shares of our outstanding common stock as of September 30, 2016, pursuant to this repurchase program, of which 263,537 shares were repurchased during the third quarter of 2016 at an average price of $62.08 per share. As of September 30, 2016 , we had up to $48.5 million of authorization remaining pursuant to this stock repurchase program. On December 15, 2014, 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. We completed that program during the fourth quarter of 2015. In total, we repurchased 1,881,921 shares of our outstanding common stock under that program at an average price of $53.13 per share. DERIVATIVES We had no activity during the nine months ended September 30, 2016 and 2015 that required hedge or derivative accounting treatment. However, 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 September 30, 2016 , these contracts covered approximately 21% of our expected average monthly natural gas requirements for the remainder of 2016. Historically, these contracts have qualified for treatment as “normal purchases or normal sales” under authoritative guidance and thus required no mark-to-market adjustment.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Adopted and New Accounting Standards	Recently Adopted and New Accounting Standards In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments . The update amends the guidance in Accounting Standards Codification 230, Statement of Cash Flows, and clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows with the objective of reducing the existing diversity in practice related to eight specific cash flow issues. The amendments in this update are effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted; however, we currently anticipate adopting the standard on its effective date. We do not expect the adoption of ASU 2016-15 to have a material impact on our consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments (Topic 326), which establishes guidance on the measurement and recognition of credit losses on most financial assets. For trade receivables, loans, and held-to-maturity debt securities, the current probable loss recognition methodology is being replaced by an expected credit loss model. The guidance will become effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The guidance is consistent with our current methodology for calculating the allowance on trade receivables, and therefore, we do not anticipate that the adoption of this standard will have a material impact on our consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (Topic 718). Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”), which simplifies several aspects related to the accounting for share-based payment transactions, including the accounting for income taxes, statutory tax withholding requirements and classification on the statement of cash flows. The standard requires all excess tax benefits and deficiencies to be recognized discretely as income tax expenses or benefits in the reporting period in which they occur. The standard is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods, with early adoption permitted. We will adopt ASU 2016-09 in the first quarter of 2017 and, based on our preliminary assessment, currently believe the most significant impact of our adoption of ASU 2016-09 to our consolidated financial statements will be to recognize in our provision for income taxes line on our Consolidated Statement of Operations, instead of to consolidated equity, certain tax benefits or tax shortfalls upon a restricted stock award vesting, performance share award settlement, or stock option exercise relative to the deferred tax asset position established. 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. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. Based on our preliminary assessment, we determined the adoption 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. We are continuing our assessment, which may identify other impacts, and we are addressing necessary policy and process changes in preparation for adoption. 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 will also result in enhanced disclosures about revenue, provide guidance for transactions that were not previously addressed comprehensively, such as service revenue and contract modifications, and clarify guidance for multiple-element arrangements. This standard was originally issued as effective for fiscal years and interim periods within those years beginning after December 15, 2016, with early adoption prohibited. However, in July 2015, the FASB approved deferring the effective date by one year to December 15, 2017 for annual reporting periods beginning after that date. In its approval, the FASB also permitted the early adoption of the standard, but not before the original effective date of fiscal years beginning after December 15, 2016. The standard may be applied under either a retrospective or cumulative effect adoption method. We plan on adopting the standard on the deferred effective date under the cumulative effect adoption method. Additionally, the new guidance requires enhanced disclosures, including revenue recognition policies to identify performance obligations to customers and significant judgments in measurement and recognition. Based on our preliminary assessment, we do not anticipate the adoption of this standard will have a material impact on our consolidated financial statements. We anticipate enhancing our disclosures upon the adoption of this standard. We are continuing our assessment, which may identify other impacts. We reviewed all other new accounting pronouncements issued in the period and concluded that they are not applicable to our business.

Income Tax Disclosure [Abstract]
Taxes	Income Taxes Consistent with authoritative guidance, our estimated annual effective tax rate is used to allocate our expected annual income tax provision to interim periods. The rate is the ratio of our estimated annual income tax provision 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 provision 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 quarterly tax provision and our quarterly estimate of our annual effective tax rate is subject to significant variation due to several factors, including variability in our pre-tax and taxable income. During the quarter, we recorded the year-to-date impact of a 0.4% increase to the estimated annual effective tax rate. For the three months ended September 30, 2016, low pre-tax income due primarily to our major maintenance in the period, coupled with immaterial adjustments to permanent items in the period arising from the change in the estimated annual effective rate, resulted in a quarterly tax rate of 48.8% . Our estimated annual effective tax rate for 2016 is approximately 36% .

During the nine months ended September 30, 2015 , we made contributions of $3.2 million to our qualified pension plans. We do not expect, nor are we required, to make contributions in 2016 . During the nine months ended September 30, 2016 , we made contributions of $0.3 million to our company-sponsored non-qualified pension plan. We estimate contributions will total $0.4 million in 2016 . We do not anticipate funding our OPEB plans in 2016 except to pay benefit costs as incurred during the year by plan participants. During the three and nine months ended September 30, 2016 , less than $0.1 million and $0.8 million , respectively, of net periodic pension and OPEB costs were charged to "Cost of sales," and $0.1 million and $0.6 million , respectively, were charged to "Selling, general and administrative expenses" in the accompanying Consolidated Statements of Operations, excluding the settlement charge discussed below. During the three and nine months ended September 30, 2015 , $1.7 million and $5.1 million , respectively, of net periodic pension and OPEB costs were charged to "Cost of sales" and $0.8 million and $2.3 million , respectively, were charged to "Selling, general and administrative expenses" in the accompanying Consolidated Statements of Operations. We announced a voluntary, limited-time opportunity for former employees who are vested participants in certain of our qualified pension plans to request early payment of their entire pension plan benefit in the form of a single lump sum payment. The amount of total payments under this program totaled approximately $10.6 million for salaried employees and $4.8 million for hourly employees and were made from the applicable plan's trust assets during the third quarter of 2016. Based on the level of payments made, settlement accounting rules applied to our salaried plan and resulted in a remeasurement of that plan as of August 31, 2016. As a result of the plan remeasurement, the net salaried plan liability, included in the "Liabilities for pensions and other postretirement employee benefits" balance in our accompanying Consolidated Balance Sheet, increased $0.8 million primarily due to a decrease in the discount rate. The discount rate used in the salaried plan remeasurement was 3.80% , compared to 4.70% at December 31, 2015. The increase in the net salaried plan liability was offset by asset returns and other year to date activity for the salaried pension plan. Additionally, as a result of settlement accounting, we recognized a pro-rata portion of the unamortized net actuarial loss, after remeasurement, resulting in a $3.5 million non-cash charge to our earnings in the third quarter of 2016. This settlement charge was recorded to "Cost of sales" and "Selling, general and administrative expenses" for $1.9 million and $1.6 million , respectively, in our Consolidated Statement of Operations for the three and nine months ended September 30, 2016.

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 September 30, Nine Months Ended September 30, (In thousands) 2016 2015 2016 2015 Restricted stock units $ 352 $ 572 $ 1,012 $ 1,535 Performance shares 877 1,182 2,313 3,225 Stock options 792 636 2,076 1,577 Total employee equity-based compensation $ 2,021 $ 2,390 $ 5,401 $ 6,337 During the first nine months of 2016 , 3,000 RSUs were settled and distributed in the first quarter, 20,000 were settled and distributed in the second quarter, and 1,250 were settled and distributed in the third quarter. After adjusting for minimum tax withholdings, a net 1,892 shares, 13,252 shares, and 908 shares were issued during each respective period. For the nine months ended September 30, 2016 , the minimum tax withholding payments made totaled $0.5 million . The following table summarizes the number of share-based awards granted under the Clearwater Paper Corporation 2008 Stock Incentive Plan during the nine months ended September 30, 2016 and the grant-date fair value of the awards: Nine Months Ended September 30, 2016 Number of Shares Subject to Award Average Fair Value of Award Per Share Restricted stock units 44,627 $ 39.10 Performance shares 93,397 39.70 Stock options 280,191 14.42 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 expense of $0.1 million and a benefit of $1.9 million for the three months ended September 30, 2016 and 2015 , respectively. For the nine months ended September 30, 2016 and 2015 , we recorded director equity-based compensation expense of $4.4 million and a benefit of $3.8 million , respectively. As of September 30, 2016 , 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 $7.6 million and $3.2 million , respectively. At December 31, 2015 , all liability amounts associated with director equity-based compensation were included in "Other long-term obligations" totaled $9.4 million .

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, 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.

Risks and Uncertainties [Abstract]
Business Insurance Recoveries [Text Block]	NOTE 14 Business Interruption and Insurance Recovery On July 6, 2016, our Lewiston, Idaho facility experienced an electrical incident that caused a complete plant-wide power outage. Power was restored in approximately 18 hours. However, damage to certain equipment limited pulping operations throughout the remainder of July. In addition to repair costs, we incurred other various costs, including incremental pulp replacement costs, incremental natural gas costs, lost electrical generation and increased labor, chemical and wood costs. We maintain property and business interruption insurance and filed a claim with our insurance provider to recover the cost of repairs to the equipment and estimated lost profits due to the disruption of the operations during the repair period. All associated costs and insurance recoveries were recorded in "Cost of sales" in our Consolidated Statement of Operations and included in the "Net earnings" line in our Consolidated Statement of Cash Flows. The insurance claim for this event totaled $8.5 million . The claim was settled in its entirety in September 2016, and, net of the policy deductible and certain exclusions totaling $3.5 million , we received $5.0 million from our property insurance provider as final payment of the claim.

Nature of Operations and Basi24

Nature of Operations and Basis of Presentation (Policies)	9 Months Ended
Nature of Operations and Basis of Presentation (Policies)	Sep. 30, 2016
Accounting Policies [Abstract]
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 requiring 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, 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 to be cash equivalents. SHORT-TERM INVESTMENTS AND RESTRICTED CASH Our short-term investments are invested primarily in demand deposits, which have very short maturity periods, and therefore earn an interest rate commensurate with low-risk instruments. Our restricted cash in which the underlying instrument has a term of greater than twelve months from the balance sheet date is classified as non-current and is included in “Other assets, net” on our Consolidated Balance Sheet. As discussed above, the indemnity escrow related to the sale of our former specialty business and mills was settled during the three months ended September 30, 2016 . Consequently, the $2.3 million restricted cash escrow account, reflected in "Restricted cash" on our Consolidated Balance Sheet at December 31, 2015, was released during the third quarter of 2016, and we had no restricted cash on our Consolidated Balance Sheet at September 30, 2016 .
TRADE ACCOUNTS RECEIVABLE	TRADE ACCOUNTS RECEIVABLE 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 September 30, 2016 and December 31, 2015 , we had allowances for doubtful accounts of $1.3 million and $1.4 million , respectively.
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 $1,571.9 million and $1,512.1 million at September 30, 2016 and December 31, 2015 , respectively. For the three and nine months ended September 30, 2016 , we capitalized $0.7 million and $1.6 million , respectively, of interest expense associated with the construction of a continuous pulp digester at our Lewiston, Idaho pulp and paperboard facility. For the three and nine months ended September 30, 2015, we capitalized $0.1 million and $0.2 million , respectively, of interest expense associated with this project. 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 new 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 1,098,568 shares of our outstanding common stock as of September 30, 2016, pursuant to this repurchase program, of which 263,537 shares were repurchased during the third quarter of 2016 at an average price of $62.08 per share. As of September 30, 2016 , we had up to $48.5 million of authorization remaining pursuant to this stock repurchase program. On December 15, 2014, 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. We completed that program during the fourth quarter of 2015. In total, we repurchased 1,881,921 shares of our outstanding common stock under that program at an average price of $53.13 per share.
DERIVATIVES	DERIVATIVES We had no activity during the nine months ended September 30, 2016 and 2015 that required hedge or derivative accounting treatment. However, 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 September 30, 2016 , these contracts covered approximately 21% of our expected average monthly natural gas requirements for the remainder of 2016. Historically, these contracts have qualified for treatment as “normal purchases or normal sales” under authoritative guidance and thus required no mark-to-market adjustment.

[1]	For the nine months ended September 30, 2016 and 2015, net periodic costs associated with our pension and other postretirement employee benefit, or OPEB, plans included in other comprehensive income and reclassified from accumulated other comprehensive loss included $2.8 million and $9.5 million, respectively, of actuarial loss amortization, as well as $1.3 million and $1.6 million, respectively, of prior service credit amortization, all net of tax totaling $0.6 million and $3.1 million, respectively. These accumulated other comprehensive loss components are included in the computation of net periodic pension and OPEB costs in Note 10, “Pension and Other Postretirement Employee Benefit Plans.” 2 Included in "Amounts reclassified from accumulated other comprehensive loss" above for the nine months ended September 30, 2016 is settlement expense of $3.5 million associated with the remeasurement of our salaried pension plan, which is discussed further in Note 10, “Pension and Other Postretirement Employee Benefit Plans.” The remeasurement resulted in a settlement loss of $0.8 million recorded to the pension liability and reclassified from accumulated other comprehensive loss. The settlement expense and corresponding remeasurement are net of tax totaling $1.1 million.

[1]	For the nine months ended September 30, 2016 and 2015, net periodic costs associated with our pension and other postretirement employee benefit, or OPEB, plans included in other comprehensive income and reclassified from accumulated other comprehensive loss included $2.8 million and $9.5 million, respectively, of actuarial loss amortization, as well as $1.3 million and $1.6 million, respectively, of prior service credit amortization, all net of tax totaling $0.6 million and $3.1 million, respectively. These accumulated other comprehensive loss components are included in the computation of net periodic pension and OPEB costs in Note 10, “Pension and Other Postretirement Employee Benefit Plans.” 2 Included in "Amounts reclassified from accumulated other comprehensive loss" above for the nine months ended September 30, 2016 is settlement expense of $3.5 million associated with the remeasurement of our salaried pension plan, which is discussed further in Note 10, “Pension and Other Postretirement Employee Benefit Plans.” The remeasurement resulted in a settlement loss of $0.8 million recorded to the pension liability and reclassified from accumulated other comprehensive loss. The settlement expense and corresponding remeasurement are net of tax totaling $1.1 million.
