New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Standards [Text Block]	RECENTLY ISSUED ACCOUNTING STANDARDS: Accounting Standards Not Yet Effective In February 2016, the Financial Accounting Standards Board (FASB) issued ASU 2016-02, Leases (Topic 842), which will require lessees to recognize leases on their balance sheets as a right-of-use asset with a corresponding liability. Lessees are permitted to make an accounting policy election to not recognize an asset and liability for leases with a term of 12 months or less. Additional qualitative and quantitative disclosures, including significant judgments made by management, will also be required. The new standard will become effective for the Company beginning January 1, 2019, and previously required the use of a modified retrospective adoption approach. In July 2018, the FASB approved another, optional, transition method that would instead allow companies to initially apply the new lease standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company plans to elect the cumulative-effect adjustment transition method. Changes to processes and internal controls to meet the standard's reporting and disclosure requirements are being assessed. The Company is currently implementing a lease management system to support the new accounting requirements. At December 31, 2017, the Company disclosed approximately $615 million in aggregate future minimum operating lease payments and continues to evaluate those contracts as well as other existing arrangements to determine whether a right-of-use asset or lease liability will need to be recognized under the new standard and will assess new contracts entered into prior to the adoption of the new standard. The adoption of the new standard will result in a material increase to right of use assets and lease liabilities on the Company's consolidated balance sheet, primarily as a result of operating leases currently not recognized on the balance sheet. The Company, however, does not anticipate a material impact to its operating results or liquidity as a result of the adoption of this new standard and is currently evaluating disclosure requirements. In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment, which simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. The amendments will become effective for the Company beginning January 1, 2020. Early adoption is permitted. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements. In January 2018, the FASB issued ASU 2018-01, Leases (Topic 842), Land Easement Practical Expedient for Transition to Topic 842, which permits an entity to make an election not to apply Topic 842 to land easements that existed or expired before the effective date of Topic 842 provided that they were not previously assessed under ASC 840, Leases. Effective January 1, 2019, Topic 842 will be applied to new and modified land easements to determine whether the arrangement should be accounted for as a lease. Upon the Company's adoption of Topic 842, the Company intends to apply this guidance by making an election to not apply Topic 842 to its land easements that existed or expired before January 1, 2019. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure for Fair Value Measurement. The amendments modify the disclosure requirements for fair value measurements in ASC 820 based on revisions to the FASB Concepts Statement, Conceptual Framework for Financial Reporting (Concepts Statement), and cost/benefit considerations. The amendments will become effective for the Company beginning January 1, 2020. Early adoption is permitted. The Company does not expect the adoption of this guidance to have a material impact on its disclosure requirements. In August 2018, the FASB issued ASU 2018-14, Compensation–Retirement Benefits–Defined Benefit Plans–General (Subtopic 715-20): Changes to the Disclosure Requirements for Defined Benefit Plans. The amendments modify the disclosure requirements for employers that sponsor defined benefit pension plans or other postretirement benefit plans to make disclosure requirements more consistent with the revisions to the Concepts Statement. The amendments will become effective for the Company beginning January 1, 2021. Early adoption is permitted on a retrospective basis to all periods presented. The Company is still evaluating the impact of this guidance on disclosure requirements.

RECENTLY ISSUED ACCOUNTING STANDARDS:

Accounting Standards Not Yet Effective

In February 2016, the Financial Accounting Standards Board (FASB) issued ASU 2016-02, Leases (Topic 842), which will require lessees to recognize leases on their balance sheets as a right-of-use asset with a corresponding liability.
