Recently Issued Accounting Pronouncements [Abstract]
Recently Issued Accounting Pronouncements Disclosure [Text Block]	2. Recently Issued Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses rather than incurred losses to estimate credit losses on certain types of financial instruments, including trade receivables. This may result in the earlier recognition of allowances for losses. The ASU is effective for public entities for fiscal years beginning after December 15, 2019, with early adoption permitted. In May 2019, the FASB issued ASU No. 2019-05, Financial Instruments – Credit Losses (Topic 326): Targeted Transition Relief, which provided additional implementation guidance on the previously issued ASU. Management has not yet completed its assessment of the impact of the new standard on the Company’s Consolidated Financial Statements. Currently, the Company believes that the most notable impact of this ASU will relate to its processes around the assessment of the adequacy of its allowance for doubtful accounts on trade accounts receivable and the recognition of credit losses. In August 2018, the FASB issued ASU No. 2018-14, Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans, which amends ASC 715 to add, remove and clarify disclosure requirements related to defined benefit pension and other postretirement plans. The ASU is effective for public entities for fiscal years beginning after December 15, 2020, with early adoption permitted. Management has not yet completed its assessment of the impact of the new standard on the Company’s Consolidated Financial Statements. In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Topic 815, Derivatives and Hedging, which updates certain guidance previously issued in ASU No. 2017-12, Derivatives and Hedging (Topic 815). The ASU is effective as of January 1, 2020, which is the beginning of the first annual period beginning after the issuance of the ASU for public entities that have adopted ASU No. 2017-12. Entities may elect either to retrospectively apply all amendments in the ASU or to prospectively apply all amendments as of the date of adoption of the ASU. Management has not yet completed its assessment of the impact of the new standard on the Company’s Consolidated Financial Statements. Recently Adopted Accounting Pronouncements In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815) which amends the hedge accounting recognition and presentation requirements in ASC 815, Derivatives and Hedging. The Board’s objectives in issuing the ASU are to (1) improve the transparency and understandability of information conveyed to financial statement users about an entity’s risk management activities by better aligning the entity’s financial reporting for hedging relationships with those risk management activities and (2) reduce the complexity of and simplify the application of hedge accounting by preparers. The ASU is effective for annual reporting periods, including interim periods within those annual reporting periods, beginning after December 15, 2018. The Company adopted this guidance as of January 1, 2019, and it did not have a material impact on its consolidated financial position, results of operations and cash flows. In February 2016, the FASB issued ASU No. 2016-02, Leases, which is intended to improve financial reporting about leasing transactions. The update requires a lessee to record on its balance sheet the assets and liabilities for the rights and obligations created by lease terms of more than 12 months. The update is effective for fiscal years beginning after December 15, 2018. A modified retrospective transition approach is required for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company elected to utilize a practical expedient in its method of adoption of the standard and adopted the guidance as of January 1, 2019. Under this expedient, which is a “current-period adjustment method,” the Company applied ASC 842 as of January 2019 and recognized operating lease liabilities of $11.7 million and right of use assets of $9.4 million for all leases with lease terms of more than 12 months. There was no impact to retained earnings as of that date. In addition, the Company adopted the guidance by electing the following practical expedients: (1) the Company did not reassess whether any expired or existing contracts contained leases, (2) the Company did not reassess the lease classification for any expired or existing leases, and (3) the Company excluded variable payments from the lease contract consideration and recorded those as incurred. The Company’s future commitments under lease obligations and additional disclosures are summarized in Note 12.
