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 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, 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.

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 June 30, 2017 and December 31, 2016, we had allowances for doubtful accounts of $1.3 million and $1.5 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 $1,626.0 million and $1,582.0 million at June 30, 2017 and December 31, 2016, respectively.

For the six months ended June 30, 2017, we capitalized $1.8 million of interest expense associated with the construction of a continuous pulp digester at our Lewiston, Idaho pulp and paperboard facility and $0.2 million associated with the construction of a paper machine at our Shelby, North Carolina consumer products facility. For the six months ended June 30, 2016, we capitalized $0.9 million of interest expense associated with the continuous pulp digester project. During the three months ended June 30, 2017, we received land with a fair market value of $4.2 million from the City of Shelby, North Carolina and Cleveland County. We must fulfill certain obligations within five years or repay the value of the land or return the title to the land. This balance is included in "Property, plant, and equipment, net," with a corresponding amount in "Other long-term obligations" on our Consolidated Balance Sheet as of June 30, 2017.

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 millionof 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 repurchased1,440,696 shares of our outstanding common stock as of June 30, 2017, pursuant to this repurchase program, of which84,750shares were repurchased during the first quarter of 2017 at an average price of$57.53per share. We did not repurchase shares during the second quarter. As of June 30, 2017, we had up to $29.8 millionof authorization remaining pursuant to this stock repurchase program.

DERIVATIVES

DERIVATIVES

We had no activity during the three and six months ended June 30, 2017 and 2016 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 June 30, 2017, these contracts covered approximately 30% of our expected average monthly natural gas requirements for the remainder of 2017, and a lesser amount for 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.
