New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU No. 2014-09”). ASU No. 2014-09 clarifies the principles for recognizing revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance affects entities that enter into contracts with customers to transfer goods or services, and supersedes prior GAAP guidance, namely Accounting Standards Codification Topic 605—Revenue Recognition. In August 2015, the FASB issued ASU No. 2015-14, “Revenue from Contracts with Customers (Topic 606)”, which delays the effective date of ASU No. 2014-09 by one year. As a result, ASU No. 2014-09 will be effective for fiscal years beginning after December 15, 2017, with early adoption permitted but not prior to the original effective date of annual periods beginning after December 15, 2016. ASU 2014-09 is to be applied retrospectively, or on a modified retrospective basis. The Company plans to apply ASU 2014-09 retrospectively as of January 1, 2018 and is currently evaluating the impact on its Consolidated Financial Statements. In April 2015, the FASB issued ASU No. 2015-03, “Interest—Imputation of Interest (Subtopic 835-30)” (“ASU No. 2015-03”). ASU No. 2015-03 aims to simplify the presentation of debt issuance costs by requiring debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. Currently, debt issuance costs are presented as a deferred charge under GAAP. ASU No. 2015-03 is effective for fiscal years beginning after December 15, 2015, and is to be applied retrospectively, with early adoption permitted. The Company has early adopted ASU No. 2015-03 during the year ended December 31, 2015 resulting in $1.2 million of debt issuance costs, net of accumulated amortization, presented as a direct deduction to the Company’s Long-term debt in the Consolidated Balance Sheet as of December 31, 2015. The retrospective application of ASU No. 2015-03 decreased Other assets and Long-term debt by $2.4 million in the Consolidated Balance Sheet as of December 31, 2014. The Company has applied the provisions of ASU No. 2015-15, “Interest—Imputation of Interest (Subtopic 835-30)” and presents deferred costs associated with its line-of-credit agreements as an asset in the Consolidated Balance Sheet. In May 2015, the FASB issued ASU No. 2015-07, “Fair Value Measurement (Topic 820)—Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent) (Subtopic 835-30)” (“ASU No. 2015-07”). ASU No. 2015-07 aims to remove the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. ASU 2015-07 also removes the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practical expedient. Investments that calculate net asset value per share (or its equivalent), but for which the practical expedient is not applied will continue to be included in the fair value hierarchy along with the related required disclosures. ASU No. 2015-07 is effective for fiscal years beginning after December 15, 2015, and is to be applied retrospectively, with early adoption permitted. The Company has early adopted ASU No. 2015-07 in the Notes to Financial Statements as of December 31, 2015 and has applied the disclosure provisions of ASU No. 2015-07 to all investments measured using the net asset value per share practical expedient. See Note 13, “Defined Benefit Plans” for further discussion on the impact of ASU No. 2015-07. In July 2015, the FASB issued ASU No. 2015-11, “Inventory (Topic 330)—Simplifying the Measurement of Inventory” (“ASU No. 2015-11”). ASU No. 2015-11 requires an entity to measure inventory at the lower of cost and net realizable value, except for inventory that is measured using the last-in, first-out method or the retail inventory method. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. ASU No. 2015-11 is effective for fiscal years beginning after December 15, 2016 and is to be applied prospectively with early adoption permitted. The Company is currently evaluating the impact of adopting ASU No. 2015-11 on its Consolidated Financial Statements. In September 2015, the FASB issued ASU No. 2015-16, “Business Combinations (Topic 805)— Simplifying the Accounting for Measurement-Period Adjustments” (“ASU No. 2015-16”). ASU No. 2015-16 aims to simplify measurement period adjustments resulting from business combinations by requiring that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date, will be recorded in the same period’s financial statements as the measurement period adjustment. ASU No. 2015-16 is effective for fiscal years beginning after December 15, 2015, and is to be applied prospectively to adjustments to provisional amounts that occur after the effective date of ASU No. 2015-16. The Company will adopt ASU No. 2015-16 prospectively in the fiscal period beginning after December 15, 2015. In November 2015, the FASB issued ASU No. 2015-17, “Income Taxes (Topic 740)—Balance Sheet Classification of Deferred Taxes” (“ASU No. 2015-17”). ASU No. 2015-17 requires deferred tax assets and liabilities to be classified as noncurrent in the Consolidated Balance Sheets. The standard will be effective for fiscal years beginning after December 15, 2016. Early adoption is permitted for financial statements that have not been previously issued. ASU No. 2015-17 may be applied either prospectively or retrospectively to all periods presented. The Company has early adopted ASU No. 2015-17 during the year ended December 31, 2015. The retrospective application of ASU No. 2015-17 decreased Other current assets, Accrued liabilities and Other liabilities by $26.2 million, $6.2 million and $18.6 million, respectively, and increased Other assets by $1.4 million in the Consolidated Balance Sheet as of December 31, 2014.
