| Accounting Policies [Abstract] | |
| Changes in Significant Accounting Policies | Note 2. Changes in Significant Accounting Policies In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (ASU 2019-12), which simplifies various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in ASC 740 and also clarifies and amends existing guidance to improve consistent application. This guidance is effective for entities for the fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020 on a prospective basis, with early adoption permitted. On July 1, 2021, the Company adopted the new standard and the adoption of ASU 2019-12 did not have a material effect on the Company’s financial statements. |
