Description of New Accounting Pronouncements Not yet Adopted [Text Block]	Note 3 – Recently Issued Accounting Standards Recently Issued Accounting Standards Adopted The Financial Accounting Standards Board (“FASB”) issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract in August 2018 that clarifies the accounting for implementation costs incurred in a cloud computing arrangement under a service contract. This guidance generally aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement under a service contract with the requirements for capitalizing implementation costs related to internal-use software. The guidance within this accounting standard update is effective for annual periods beginning after December 15, 2019 and should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. Early adoption was permitted. The Company adopted this standard on a prospective basis, effective January 1, 2020. There was no cumulative effect of adoption recorded within retained earnings on January 1, 2020. The FASB issued ASU 2018-14, Disclosure Framework — Changes to the Disclosure Requirements for Defined Benefit Plans in August 2018 that modifies certain disclosure requirements for fair value measurements. The guidance removes certain disclosure requirements regarding transfers between levels of the fair value hierarchy as well as certain disclosures related to the valuation processes for certain fair value measurements. Further, the guidance added certain disclosure requirements including unrealized gains and losses and significant unobservable inputs used to develop certain fair value measurements. The guidance within this accounting standard update is effective for annual and interim periods beginning after December 15, 2019, and should be applied prospectively in the initial year of adoption or prospectively to all periods presented, depending on the amended disclosure requirement. Early adoption was permitted. The Company adopted this standard on a prospective basis, effective January 1, 2020. ASU 2018-14 addresses disclosures only and will not have an impact on the Company’s consolidated financial statements. The FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments in June 2016 related to the accounting for and disclosure of credit losses. The FASB subsequently issued several additional accounting standard updates which amended and clarified the guidance, but did not materially change the guidance or its applicability to the Company. This accounting guidance introduces a new model for recognizing credit losses on financial instruments, including customer accounts receivable, based on an estimate of current expected credit losses. The guidance within this accounting standard update is effective for annual and interim periods beginning after December 15, 2019. Early adoption was permitted. The Company did not early adopt, but did adopt the guidance in this accounting standard update, including all applicable subsequent updates to this accounting guidance, as required, on a modified retrospective basis, effective January 1, 2020. Adoption did not have a material impact to the Company’s financial statements as expected. However, as a result of this adoption, the Company recorded a cumulative effect of accounting change that resulted in an increase to its allowance for doubtful accounts of $0.5 million, a decrease to deferred tax liabilities of $0.1 million and a decrease to retained earnings of $0.4 million. In accordance with this guidance, the Company recognizes an allowance for credit losses reflecting the net amount expected to be collected from its financial assets, primarily trade accounts receivable. This allowance represents the portion of the receivable that the Company does not expect to collect over its contractual life, considering past events and reasonable and supportable forecasts of future economic conditions. The Company’s allowance for credit losses on its trade accounts receivable is based on specific collectability facts and circumstances for each outstanding receivable and customer, the aging of outstanding receivables and the associated collection risk the Company estimates for certain past due aging categories, and also, the general risk to all outstanding accounts receivable based on historical amounts determined to be uncollectible. Recently Issued Accounting Standards Not Yet Adopted The FASB issued Account Standards Update (“ASU”) 2020-01 Investments – Equity Securities (Topic 321), Investments – Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) –Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 in January 2020 clarifying the interaction among the accounting standards related to equity securities, equity method investments, and certain derivatives. The new guidance, among other things, states that a company should consider observable transactions that require a company to either apply or discontinue the equity method of accounting, for the purposes of applying the fair value measurement alternative immediately before applying or upon discontinuing the equity method. The new guidance also addresses the measurement of certain purchased options and forward contracts used to acquire investments. The guidance within this accounting standard update is effective for annual and interim periods beginning after December 15, 2020 and is to be applied prospectively. Early adoption is permitted. The Company has not early adopted the guidance and is currently evaluating its implementation. The FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes in December 2019 to simplify the accounting for income taxes. The guidance within this accounting standard update removes certain exceptions, including the exception to the incremental approach for certain intra-period tax allocations, to the requirement to recognize or not recognize certain deferred tax liabilities for equity method investments and foreign subsidiaries, and to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. Further, the guidance simplifies the accounting related to franchise taxes, the step up in tax basis for goodwill, current and deferred tax expense, and codification improvements for income taxes related to employee stock ownership plans. The guidance is effective for annual and interim periods beginning after December 15, 2020. Early adoption is permitted. The Company has not early adopted the guidance and is currently evaluating its implementation. The FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement in August 2018 that modifies certain disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The amendments in this accounting standard update remove disclosures that are no longer considered cost beneficial, clarify the specific requirements of certain disclosures, and add new disclosure requirements as relevant. The guidance within this accounting standard update is effective for annual periods beginning after December 15, 2020, and should be applied retrospectively to all periods presented. Early adoption is permitted. The Company has not early adopted the guidance and is currently evaluating its implementation.
