Present and Prospective Accounting [Abstract] |
New Accounting Pronouncements, Policy [Policy Text Block] | 2. PRESENT AND PROSPECTIVE ACCOUNTING PRONOUNCEMENTS Recently Adopted Accounting Policies In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326). This ASU sets forth a "current expected credit loss" (CECL) model, which requires the measurement of all expected credit losses for financial instruments or other assets (e.g., trade receivables), held at the reporting date based on historical experience, current conditions, and reasonable supportable forecasts. The Company adopted ASU 2016-13 on January 1, 2020. This adoption did not have a material impact on the Company’s Consolidated Financial Statements. In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350). The standard simplifies the accounting for goodwill impairments by eliminating step 2 from the goodwill impairment test. The Company adopted ASU 2017-14 on January 1, 2020. This adoption did not have a material impact on the Company’s Consolidated Financial Statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (Topic 820). The standard amends ASC 820 to add and remove disclosure requirements related to fair value measurement. The Company adopted ASU 2018-13 on January 1, 2020. This adoption did not have a material impact on the Company’s Consolidated Financial Statements. In August 2018, the FASB issued ASU 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract (Subtopic 350-40). The standard provides additional guidance on the accounting for costs of implementation activities performed in a cloud computing arrangement that is a service contract. The Company adopted ASU 2018-15 on January 1, 2020, using the prospective transition method. This adoption did not have a material impact on the Company’s Consolidated Financial Statements. In August 2018, the FASB issued ASU 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 amended guidance modifies the disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans by removing and adding certain disclosures for these plans. The eliminated disclosures include (a) the amounts in accumulated other comprehensive income expected to be recognized in net periodic benefit costs over the next fiscal year, and (b) the effects of a one percentage point change in assumed health care cost trend rates on the net periodic benefit costs and the benefit obligation for post-retirement health care benefits. Additional disclosures include descriptions of significant gains and losses affecting the benefit obligation for the period. The Company adopted ASU 2018-14 during 2020. The adoption of this guidance modified our disclosures but did not have a material effect on our Consolidated Financial Statements. Accounting Standards Issued But Not Yet Adopted In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (Topic 740). This ASU simplifies the accounting for income taxes by, among other things, eliminating certain existing exceptions related to the general approach in ASC 740 relating to franchise taxes, reducing complexity in the interim-period accounting for year-to-date loss limitations and changes in tax laws, and clarifying the accounting for transactions outside of business combination that result in a step-up in the tax basis of goodwill. The transition requirements are primarily prospective, and the effective date is for interim and annual reporting periods beginning after December 15, 2020, with early adoption permitted. We are currently evaluating the impact of the new guidance on our Consolidated Financial Statements.
