Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies [Text Block]	Impact of Recently Issued Accounting Standards In August 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2017-12, Derivatives and Hedging (Topic 815) ("ASU No. 2017-12"). ASU No. 2017-12 simplifies certain aspects of hedge accounting and results in a more accurate portrayal of the economics of an entity’s risk management activities in its financial statements. ASU No. 2017-12 is effective for the company in the first quarter of 2019, with early adoption permitted, and is to be applied on a modified retrospective basis. The company is currently evaluating the potential effects of adopting the provisions of ASU No. 2017-12. In May 2017, the FASB issued Accounting Standards Update No. 2017-09, Compensation - Stock Compensation (Topic 718) ("ASU No. 2017-09"). ASU No. 2017-09 clarifies which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. Effective April 2, 2017, the company adopted the provisions of ASU No. 2017-09 on a prospective basis. The adoption of the provisions of ASU No. 2017-09 did not materially impact the company's consolidated financial position or results of operations. In March 2017, the FASB issued Accounting Standards Update No. 2017-07, Compensation - Retirement Benefits (Topic 715) ("ASU No. 2017-07"). ASU No. 2017-07 requires that the service cost component of pension expense be included in the same line item as other compensation costs arising from services rendered by employees, with the other components of pension expense being classified outside of a subtotal of income from operations. ASU No. 2017-07 is effective for the company in the first quarter of 2018 and is to be applied retrospectively for the presentation requirements and prospectively for the capitalization of the service cost component requirements. The adoption of the provisions of ASU No. 2017-07 is not expected to have a material impact on the company's consolidated financial position or results of operations. In January 2017, the FASB issued Accounting Standards Update No. 2017-04, Intangibles - Goodwill and Other (Topic 350) ("ASU No. 2017-04"). ASU No. 2017-04 eliminates step 2 from the annual goodwill impairment test. Effective January 1, 2017, the company adopted the provisions of ASU No. 2017-04 on a prospective basis. The adoption of the provisions of ASU No. 2017-04 would not materially impact the company's consolidated financial position or results of operations unless step 1 of the annual goodwill impairment test fails. In October 2016, the FASB issued Accounting Standards Update No. 2016-16, Income Taxes - Intra-Entity Transfers of Assets Other Than Inventory (Topic 740) ("ASU No. 2016-16"). ASU No. 2016-16 clarifies the accounting for the current and deferred income taxes for an intra-entity transfer of an asset other than inventory. Effective April 2, 2017, the company adopted the provisions of ASU No. 2016-16 on a modified retrospective basis. The adoption of the provisions of ASU No. 2016-16 did not materially impact the company's consolidated financial position or results of operations. In August 2016, the FASB issued Accounting Standards Update No. 2016-15, Statement of Cash Flows (Topic 230) ("ASU No. 2016-15"). ASU No. 2016-15 addresses how certain cash receipts and cash payments are presented and classified in the statement of cash flows. Effective January 1, 2017, the company adopted the provisions of ASU No. 2016-15 on a retrospective basis. The adoption of the provisions of ASU No. 2016-15 did not materially impact the company's consolidated financial position or results of operations. In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments - Credit Losses (Topic 326) ("ASU No. 2016-13"). ASU No. 2016-13 revises the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. ASU No. 2016-13 is effective for the company in the first quarter of 2020, with early adoption permitted, and is to be applied using a modified retrospective approach. The company is currently evaluating the potential effects of adopting the provisions of ASU No. 2016-13. In March 2016, the FASB issued Accounting Standards Update No. 2016-09, Stock Compensation - Improvements to Employee Share-Based Payment Accounting (Topic 718) ("ASU No. 2016-09"). ASU No. 2016-09 revises the accounting treatment for excess tax benefits, minimum statutory tax withholding requirements, and forfeitures related to share-based awards. Effective January 1, 2017, the company adopted the recognition of excess tax benefits and tax deficiencies on a prospective basis and reclassified excess tax benefits in the consolidated statements of cash flows on a retrospective basis. The company elected to continue to estimate forfeitures expected to occur to determine the amount of compensation cost to be recognized in each period. The adoption of the provisions of ASU No. 2016-09 did not materially impact the company's consolidated financial position or results of operations. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) ("ASU No. 2016-02"). ASU No. 2016-02 requires the entity to recognize the assets and liabilities for the rights and obligations created by leased assets. Leases will be classified as either finance or operating, with classification affecting expense recognition in the income statement. ASU No. 2016-02 is effective for the company in the first quarter of 2019, with early adoption permitted, and is to be applied using a modified retrospective approach. While the company continues to evaluate the effects of adopting the provisions of ASU No. 2016-02, the company expects most existing operating lease commitments will be recognized as operating lease liabilities and right-of-use assets upon adoption. In January 2016, the FASB issued Accounting Standards Update No. 2016-01, Financial Instruments - Recognition and Measurement of Financial Assets and Financial Liabilities (Topic 825) ("ASU No. 2016-01"). ASU No. 2016-01 revises the classification and measurement of investments in certain equity investments and the presentation of certain fair value changes for certain financial liabilities measured at fair value. ASU No. 2016-01 requires the change in fair value of many equity investments to be recognized in net income. ASU No. 2016-01 is effective for the company in the first quarter of 2018, with early adoption permitted, and is to be applied prospectively. The company is currently evaluating the potential effects of adopting the provisions of ASU No. 2016-01. In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU No. 2014-09"). ASU No. 2014-09 supersedes all existing revenue recognition guidance. Under ASU No. 2014-09, an entity should recognize revenue when it transfers 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. ASU No. 2014-09 is effective for the company in the first quarter of 2018, with early adoption permitted in the first quarter of 2017. ASU No. 2014-09 allows for either full retrospective or modified retrospective adoption. In March, April, May, and December 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers: Principal versus Agent Considerations (Reporting Revenue Gross versus Net) ("ASU No. 2016-08"); ASU No. 2016-10, Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing ("ASU No. 2016-10"); ASU No. 2016-12, Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients ("ASU No. 2016-12"); and ASU No. 2016-19, Technical Corrections and Improvements ("ASU No. 2016-19"), respectively. ASU No. 2016-08, ASU No. 2016-10, ASU No. 2016-12, and ASU No. 2016-19 provide supplemental adoption guidance and clarification to ASU No. 2014-09, and must be adopted concurrently with the adoption of ASU No. 2014-09. The company is currently evaluating the potential effects of adopting the provisions of ASU No. 2014-09, ASU No. 2016-08, ASU No. 2016-10, ASU No. 2016-12, and ASU No. 2016-19. In 2014, the company established an implementation team (“team”) and engaged external advisers to develop a multi-phase plan to assess the company’s business and contracts, as well as any changes to processes or systems to adopt the requirements of the new revenue standard. The team has updated the assessment for new ASU updates and for newly acquired businesses. The team is in the process of finalizing its conclusions on several aspects of the standard including principal versus agent considerations, identification of performance obligations, and the determination of when control of goods and services transfers to the company’s customers. Additionally, the team is in the process of evaluating the impact of the expanded disclosure requirements.
