Accounting Standards Update and Change in Accounting Principle [Text Block] | Note B - Recent Accounting Pronouncements Recently issued accounting pronouncements not yet adopted In October 2020, the FASB issued ASU 2020 - 10, Codification Improvements. The amendments in this update ensure that all guidance that requires or provides an option for an entity to provide information in the notes of financial statements is codified in the Disclosure section of the codification and also clarifies the guidance in cases in which the original guidance may have been unclear. This guidance is effective for interim and annual reporting periods beginning after December 15, 2020, with early adoption permitted, including adoption in any interim period. The Company is currently evaluating this amendment and does not anticipate a material impact on its consolidated financial statements and related disclosures. In December 2019, the Financial Accounting Standards Board (“FASB”) issued ASU 2019 - 12, which enhances and simplifies various aspects of the income tax accounting guidance, including requirements such as tax basis step-up in goodwill obtained in a transaction that is not a business combination, ownership changes in investments, and interim-period accounting for enacted changes in tax law. The standard will be effective for us in the fiscal year 2021, although early adoption is permitted. We have not elected early adoption and we do not expect that the adoption of this accounting standard update (“ASU”) will have a significant impact on our consolidated financial statements. Recently adopted accounting pronouncements Defined Pension Plan In August 2018, the FASB issued ASU 2018 - 14, Compensation—Retirement Benefits—Defined Benefit Plans—General ( Topic 715 - 20 ): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans ( “ ASU 2018 - 14 ” ) , which modifies the disclosure requirements for defined benefit pension plans and other postretirement plans. ASU 2018 - 14 is effective for fiscal years ending after December 15, 2020, and earlier adoption is permitted. We adopted ASU 2018 - 14 as of December 31, 2020. The adoption did not have a material impact on our consolidated financial statements. Reference Rate Reform In March 2020, the FASB issued ASU 2020 - 04, “ Reference Rate Reform (Topic 848 ) – Facilitation of the Effects of Reference Rate Reform on Financial Reporting Summary ”. This ASU provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. London Inter-bank Offered Rate (“LIBOR”) and other inter-bank offered rates are widely used benchmarks or reference rates in the United States and globally. With global capital markets expected to move away from LIBOR and other inter-bank offered rates and toward more observable or transaction-based rates that are less susceptible to manipulation, the FASB launched a broad project in late 2018 to address potential accounting challenges expected to arise from the transition. The new guidance provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. This ASU is effective March 12, 2020 through December 31, 2022. We adopted this ASU on March 12, 2020 and it did not have a material impact on our consolidated financial statements. Fair Value Measurements On January 1, 2020, we adopted Accounting Standards Update No. 2018 - 13, Changes to Disclosure Requirements for Fair Value Measurements (Topic 820 ) , which improved the effectiveness of disclosure requirements for recurring and nonrecurring fair value measurement. The standard removes, modifies, and adds certain disclosure requirements. The adoption of this new standard did not have a material impact on our consolidated financial statements. Income taxes In February 2018, the FASB issued ASU 2018 - 02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income . This ASU allows for reclassification of stranded tax effects on items resulting from the change in the corporate tax rate as a result of H.R. 1, originally known as the Tax Cuts and Jobs Act of 2017 (the “Tax Reform Act”), from accumulated other comprehensive income to retained earnings. Tax effects unrelated to H.R. 1 are permitted to be released from accumulated other comprehensive income using either the specific identification approach or the portfolio approach, based on the nature of the underlying item. ASU 2018 - 02 is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. We adopted ASU 2018 - 02 in the first quarter of 2019. See Note I, Income Taxes, for a discussion of the impacts of this ASU. Stock-based Compensation In June 2018, the FASB issued ASU 2018 - 07, Compensation-Stock Compensation (Topic 718 ): Improvements to nonemployee share-based payment accounting, which supersedes ASC 505 - 50, Accounting for Distributions to Shareholders with Components of Stock and Cash, and expands the scope of ASC 718 to include all share-based payment arrangements related to the acquisition of goods and services from both non-employees and employees. As a result, most of the guidance in ASC 718 associated with employee share-based payments, including most of its requirements related to classification and measurement, applies to non-employee share-based payment arrangements. The ASU is effective for annual periods beginning after December 15, 2018, and the interim periods within those fiscal years with early adoption permitted after the entity has adopted ASC 606. This standard was adopted as of January 1, 2019 and did not have a material impact on our consolidated financial statements and related disclosures. Leases In February 2016, the FASB issued ASU 2016 - 02, Leases (Topic 842 ) and subsequent amendment ASU 2018 - 11, which requires all operating leases to be recorded on the balance sheet unless the practical expedient is elected for short-term operating leases. The lessee will record a liability for its lease obligations (initially measured at the present value of the future lease payments not yet paid over the lease term, and an asset for its right to use the underlying asset equal to the lease liability, adjusted for lease payments made at or before lease commencement). This ASU is effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. This change is required to be applied using a modified retrospective approach for leases that exist or are entered after the beginning of the earliest comparative period in the financial statements. Full retrospective application is prohibited. In July 2018, the FASB approved an optional transition method to initially account for the impact of the adoption with a cumulative-effect adjustment to the January 1, 2019, rather than the January 1, 2017, financial statements. This would eliminate the need to restate amounts presented prior to January 1, 2019. We adopted the standard effective January 1, 2019, and we elected the optional transition method and the practical expedients permitted under the transition guidance within the standard. Accordingly, we accounted for our existing operating leases as operating leases under the new guidance, without reassessing (a) whether the contracts contain a lease under ASC Topic 842, (b) whether classification of the operating leases would be different in accordance with ASC Topic 842, or (c) whether the unamortized initial direct costs before transition adjustments (as of December 31, 2018) would have met the definition of initial direct costs in ASC Topic 842 at lease commencement. The standard had a material impact on our consolidated balance sheets, but did not have an impact on our consolidated statements of comprehensive loss or cash flows from operations. The cumulative effect of the changes on our retained earnings was $22,000 associated with capital gain. The most significant impact was the recognition of ROU assets and lease liabilities for operating leases. Our accounting for finance leases remained substantially unchanged. See Note D, Leases for further discussion. Restricted Cash In the first quarter of 2019. the Company adopted ASU 2016 - 18, Statement of Cash flows (Topic 230 ): Restricted Cash, which enhances and clarifies the guidance on the classification and presentation of restricted cash in the statement of cash flows and requires additional disclosures about restricted cash balances. The adoption of ASU 2016 - 18 did not have a material impact on our consolidated financial statements and related disclosures.
