New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued Accounting Standards In May 2017, the FASB issued ASU 2017-09 that provides guidance about when a change to the terms or conditions of a share-based payment award must be accounted for as a modification. The new guidance requires modification accounting if the fair value, vesting condition or the classification of the award is not the same immediately before and after a change to the terms and conditions of the award. This standard is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. As the Company does not currently have any modified share-based payment awards, the Company does not expect the adoption of this standard to have a significant impact on its Consolidated Financial Statements, but will continue to assess the impact on an ongoing basis. The Company plans to adopt this standard on January 1, 2018. In March 2017, the Financial Accounting Standards Board (“FASB”) issued ASU 2017-07 primarily to improve the presentation of net periodic pension cost and net periodic post-retirement benefit cost. The new guidance requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. This standard is effective for public business entities for annual periods or any interim periods beginning after December 15, 2017, including interim periods within those periods. Early adoption is permitted. The Company does not expect the new guidance to have a significant impact on its Consolidated Financial Statements and plans to adopt this standard on January 1, 2018. In January 2017, the FASB issued ASU 2017-01, which requires a reporting entity to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or liabilities. This standard is effective for public business entities for annual periods beginning after December 15, 2017, including interim periods within those periods. Early adoption is permitted under specific circumstances. The Company does not expect the new guidance to have a significant impact on its Consolidated Financial Statements and plans to adopt this standard on January 1, 2018. In August 2016, the FASB issued ASU 2016-15 with the objective of reducing the existing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The new guidance requires evaluation of cash receipts and payments on the basis of the nature of the underlying cash flows and provides clarity for categorization for specific transactions. This standard is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company has not yet determined the effect of the standard on its ongoing financial reporting and plans to adopt this standard on January 1, 2018. In February 2016, the FASB issued ASU 2016-02, which requires a lessee to recognize a lease liability and asset for all leases, including operating leases, with a term greater than 12 months on its balance sheet. The standard requires a modified retrospective transition method for all entities. This ASU also provides clarification surrounding the presentation of the effects of the leases in the income statement and statement of cash flows. This standard is effective for public business entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The Company has not yet determined the effect of the standard on its ongoing financial reporting and plans to adopt this standard on January 1, 2019. In January 2016, the FASB issued ASU 2016-01, which requires a company to present separately in other comprehensive income, the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk if the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. This standard is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company has not yet determined the effect of the standard on its ongoing financial reporting and plans to adopt this standard on January 1, 2018. In May 2014, the FASB issued ASU 2014-09 and issued subsequent amendments to the initial guidance in August 2015, March 2016, April 2016, May 2016 and December 2016 within ASU 2015-14, ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20, respectively. The core principal of the guidance is to provide a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. The guidance also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts. Subsequently, in July 2015, the FASB elected to delay the effective date of the standard by one year to annual and interim periods beginning after December 15, 2017, which will require the Company to adopt these provisions in the first quarter of fiscal year 2018. Early application is permitted beginning with annual and interim periods beginning after December 15, 2016. This update permits the use of either the retrospective or cumulative effect transition method. The ASU 2016-12 issued in May of 2016 removes the requirement to disclose the effect of the accounting change in the period of adoption, but still requires the Company to disclose the effect of the changes on any prior periods retrospectively adjusted. The Company commenced its assessment of ASU 2014-09 in 2015 and developed a project plan to guide the implementation. This project plan includes analyzing the ASU’s impact on the Company’s contract portfolio, comparing its historical accounting policies and practices to the requirements of the new guidance, and identifying potential differences from applying the requirements of the new guidance to its contracts. The Company is also in the process of evaluating new disclosure requirements, as well as identifying and implementing appropriate changes to its business processes and controls to support recognition and disclosure under the new guidance. The Company will adopt this new guidance on January 1, 2018 using the modified retrospective method that will result in a cumulative effect adjustment as of the date of adoption. The Company is currently evaluating this guidance and the impact it will have on its Consolidated Financial Statements. Recently Adopted Accounting Standards In January 2017, the FASB issued ASU 2017-04, which simplifies an entity's measurement of goodwill for impairment testing purposes by eliminating the requirement to perform a hypothetical purchase price allocation. A goodwill impairment charge will now be recognized for the amount by which the carrying value of a reporting unit exceeds its fair value, not to exceed the carrying amount of goodwill. This standard is effective for public business entities for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company adopted this guidance on January 1, 2017. The Company's adoption of this standard did not have a significant impact on its Consolidated Financial Statements. In October 2016, the FASB issued ASU 2016-16, which requires the recognition of the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. This standard is effective for public business entities for annual periods beginning after December 15, 2018, and interim periods within annual periods beginning after December 15, 2019. Early adoption is permitted. The Company adopted this guidance effective January 1, 2017. The Company's adoption of this standard did not have a significant impact on its Consolidated Financial Statements. Refer to Note 1. Basis of Presentation for further details. In March 2016, the FASB issued ASU 2016-09. The updated guidance changes how companies account for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as the classification of related matters in the statement of cash flows. This standard is effective for public business entities for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted. The Company adopted this guidance effective January 1, 2017. The Company's adoption of this standard did not have a significant impact on its Consolidated Financial Statements. In July 2015, the FASB issued ASU 2015-11, a final standard that simplifies the subsequent measurement of inventory by replacing the lower of cost or market test under current U.S. GAAP. Under the previous guidance, the subsequent measurement of inventory was measured at the lower of cost or market, where “market” may have multiple possible outcomes. The new guidance requires subsequent measurement of inventory at the lower of cost or net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs to sell (completion, disposal, and transportation). This standard is effective for public business entities for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted. The Company adopted this guidance effective January 1, 2017. The Company's adoption of this standard did not have a significant impact on its Consolidated Financial Statements. Certain amounts in prior years have been reclassified to conform to the current year presentation as a result of recently adopted accounting standards as described in Note 1. Basis of Presentation.
