Organization, Consolidation and Presentation of Financial Statements [Abstract]

During 2016, the Company modified its presentation of byproduct recoveries to include byproduct recoveries as a reduction of cost of sales–products in the condensed consolidated statements of operations. Previously, byproduct recoveries were reported in net sales–products. Classification of byproduct recoveries as a reduction of cost of sales aligns the proceeds from byproduct recoveries with the corresponding manufacturing costs.

Fair Value Measurement

Certain assets and liabilities are required to be recorded at fair value on a recurring basis, while other assets and liabilities are recorded at fair value on a nonrecurring basis, generally as a result of acquisitions or impairment charges. Fair value is determined based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. GAAP also classifies the inputs used to measure fair value into the following hierarchy:


Level 1:	Quoted prices in active markets for identical assets or liabilities.


Level 2:	Quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability.


Level 3:	Unobservable inputs for the asset or liability. There were no Level 3 recurring measurements of assets or liabilities as of June 30, 2016.

The Company records the fair value of its forward contracts and pension plan assets on a recurring basis. The fair value of cash and cash equivalents, receivables, inventories, restricted cash, accounts payable, accrued liabilities and amounts owing in satisfaction of bankruptcy claims approximate their carrying values as of June 30, 2016, and December 31, 2015. See Note 10, "Debt," for further discussion on the fair value of the Company's debt.

In addition to assets and liabilities that are recorded at fair value on a recurring basis, the Company is required to record certain assets and liabilities at fair value on a nonrecurring basis, generally as a result of acquisitions or the remeasurement of assets resulting in impairment charges.

Pension Plans

For 2015, the Company measured interest costs utilizing a single weighted-average discount rate derived from the yield curve used to measure the plan obligations. Beginning in the first quarter of 2016, the Company changed the approach used to measure interest costs for pension benefits and elected to measure interest costs by applying the specific spot rates along that yield curve to the plans' liability cash flows. The new method would also impact the calculation of service costs, but this is not applicable to the Company's pension plans due to their frozen status. The Company made this change to provide a more precise measurement of interest costs by aligning the timing of the plans' liability cash flows to the corresponding spot rates on the yield curve. This change did not affect the measurement of the plan obligations. The Company has reflected this as a change in accounting estimate, and accordingly, has accounted for it on a prospective basis.

Earnings Per Share

The calculation of diluted earnings per share includes the effect of any dilutive equity incentive instruments. The Company uses the treasury stock method to calculate the effect of outstanding dilutive equity incentive instruments, which requires the Company to compute total proceeds as the sum of the following: (1) the amount the employee must pay upon exercise of the award; (2) the amount of unearned stock-based compensation costs attributable to future services; and (3) for the three and six months ended June 30, 2015, the amount of excess tax benefits, if any, that would be credited to additional paid-in capital, assuming exercise of the award. The calculation of total proceeds for the three and six months ended June 30, 2016, excludes the excess tax benefits as a result of the early prospective adoption of new accounting guidance related to share-based compensation during the second quarter of 2016, with retrospective application to January 1, 2016. See Note 21, "New Accounting Pronouncements," for further discussion of the adoption of the new accounting standard related to share-based compensation and its impacts to the condensed consolidated financial statements.

Equity incentive instruments for which the total employee proceeds from exercise exceed the average fair value of the same equity incentive instrument over the period have an anti-dilutive effect on earnings per share during periods with net earnings, and accordingly, the Company excludes them from the calculation. Due to the net loss incurred during the three and six months ended June 30, 2016 and 2015, the assumed exercise of all equity incentive instruments was anti-dilutive and, therefore, not included in the diluted loss per share calculation for those periods.

Share-based Compensation, Option and Incentive Plans Policy

The Company recognizes compensation expense based on estimated grant date fair values for all share-based awards issued to employees and non-employee directors, including stock options, performance shares, performance share units, restricted stock, restricted stock units and deferred stock units. The Company recognizes these compensation costs for only those awards expected to vest, on a straight-line basis over the requisite three to four year service period of the awards, except deferred stock units, which are fully vested and expensed on the grant date. The Company estimated the number of awards expected to vest based, in part, on historical forfeiture rates and also based on management's expectations of employee turnover within the specific employee groups receiving each type of award. Forfeitures are estimated at the time of grant and revised in subsequent periods if actual forfeitures differ from those estimates.

New Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2016-13 "Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" ("ASU 2016-13"), which changes the impairment model for most financial assets and certain other instruments. Under the new guidance, entities will be required to measure expected credit losses for financial instruments, including trade receivables, based on historical experience, current conditions and reasonable forecasts. This guidance is effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted for interim and annual periods beginning after December 15, 2018. This new guidance will require a modified retrospective transition approach, where the entity will need to apply a cumulative-effect adjustment to retained earnings (accumulated deficit) as of the beginning of the first reporting period in which the guidance is adopted. The Company is evaluating the impact of the adoption of ASU 2016-13 on the condensed consolidated financial statements.

In March 2016, the FASB issued Accounting Standards Update 2016-09 "Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting" ("ASU 2016-09"), which simplifies the accounting for share-based payments, including income tax consequences, accounting for forfeitures, classification of awards as either equity or liabilities and classification on the statements of cash flows. This guidance is effective for interim and annual periods beginning after December 15, 2016, with early adoption permitted. During the second quarter of 2016, the Company elected to early adopt ASU 2016-09, with retrospective application to January 1, 2016. Prior to the adoption of the ASU, excess tax benefits or expense related to stock-based compensation transactions were recognized in additional paid-in capital on the condensed consolidated balance sheets; following the adoption of the ASU, all excess tax benefits or expense related to stock-based compensation transactions are recognized prospectively as income tax expense (benefit) in the condensed consolidated statements of operations, and the excess tax benefits or expense from the stock-based compensation transactions previously included in financing activities on the condensed consolidated statements of cash flows are prospectively included as a component of net loss on the condensed consolidated statements of cash flows. See Note 15, "Loss Per Share," for the impacts of the adoption of ASU 2016-09 on the calculation of the effect of outstanding dilutive equity incentive instruments using the treasury stock method. See Note 16, "Equity Incentive Programs," for the Company's policy election on accounting for forfeitures. The adoption of ASU 2016-09 did not have a material impact on the condensed consolidated financial statements.

In March 2016, the FASB issued Accounting Standards Update 2016-07 "Investments—Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting" ("ASU 2016-07"), which simplifies the equity method of accounting by eliminating the requirement to retrospectively apply equity method accounting to an investment that subsequently qualifies for such accounting as a result of an increase in the level of ownership interest or degree of influence. Instead, the equity method of accounting will be applied prospectively as an increase in the level of ownership interest or degree of influence occurs. This guidance is effective for interim and annual periods beginning after December 15, 2016, with early adoption permitted. The Company does not believe the adoption of ASU 2016-07 will have a material impact on the condensed consolidated financial statements.

In February 2016, the FASB issued Accounting Standards Update 2016-02 "Leases (Topic 842)" ("ASU 2016-02"), which establishes a right-of-use model requiring a lessee to record a right-of-use asset and a lease liability on the balance sheet for all leases with terms longer than twelve months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition. The guidance also requires additional disclosures to enable users of financial statements to understand the amount, timing and uncertainty of cash flows arising from leases. This guidance is effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. This new guidance will require a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to elect to use certain transition relief. The modified retrospective transition approach would require the application of the new accounting model for the earliest year presented in the financial statements. The Company is evaluating the impact of the adoption of ASU 2016-02 on the condensed consolidated financial statements.

In May 2014, the FASB issued Accounting Standards Update 2014-09 "Revenue from Contracts with Customers (Topic 606)" ("ASU 2014-09"), which provides revised guidance on recognizing revenue from contracts with customers. Under this guidance, an entity will recognize revenue when it transfers promised goods or services to the customer in the amount that reflects what it expects in exchange for the goods or services. This guidance also requires more detailed disclosures to enable users of the financial statements to understand the nature, amount, timing and uncertainty of the revenue and cash flow arising from contracts with customers. This guidance allows the option of either a full retrospective adoption, meaning the guidance is applied to all periods presented, or a modified retrospective adoption, meaning the guidance is applied only to the most current period. As amended, ASU 2014-09 is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted for interim and annual periods beginning after December 15, 2016. The Company plans to adopt the standard in the first quarter of 2018. The Company is evaluating the impact of ASU 2014-09 on the condensed consolidated financial statements and currently anticipates applying the modified retrospective approach when adopting this guidance.
