Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued Accounting Pronouncements In September 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments, which changes the impairment model for most financial assets. This Update is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The underlying premise of the Update is that financial assets measured at amortized cost should be presented at the net amount expected to be collected, through an allowance for credit losses that is deducted from the amortized cost basis. The allowance for credit losses should reflect management’s current estimate of credit losses that are expected to occur over the remaining life of a financial asset. The income statement will be affected for the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. With certain exceptions, transition to the new requirements will be through a cumulative effect adjustment to opening retained earnings as of the beginning of the first reporting period in which the guidance is adopted. This Update is effective for SEC filers that are eligible to be smaller reporting companies, non-SEC filers, and all other companies, to fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. We expect to recognize a one-time cumulative-effect adjustment to the allowance for loan losses as of the beginning of the first reporting period in which the new standard is effective but cannot yet determine the magnitude of any such one-time adjustment or the overall impact of the new guidance on the consolidated financial statements. Management will continue to monitor model output throughout the deferral period. CECL Adoption. The Company continues to monitor the opportunity to early adopt ASC Topic 326, which replaces the current incurred loss approach for measuring credit losses with an expected loss model ("CECL"). CECL applies to financial assets subject to credit losses and measured at amortized cost and certain off-balance-sheet credit exposures, which include, but are not limited to, loans, leases, held-to-maturity securities, loan commitments, and financial guarantees. Expected results of adoption are challenging to foreshadow due to the evolving macroeconomic landscape. Early adoption of CECL is unlikely. In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt – Modifications and Extinguishments (Subtopic 470-50), Compensation – Stock Compensation (Topic 718), and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40), which requires an entity to treat a modification of an equity-classified warrant that does not cause the warrant to become liability-classified as an exchange of the original warrant for a new warrant. This guidance applies whether the modification is structured as an amendment to the terms and conditions of the warrant or as termination of the original warrant and issuance of a new warrant. An entity should measure the effect of a modification as the difference between the fair value of the modified warrant and the fair value of that warrant immediately before the modification. The amendments in this Update are effective for all entities for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. An entity should apply the amendments prospectively to modifications or exchanges occurring on or after the effective date of the amendments. Early adoption is permitted for all entities, including adoption in an interim period. If an entity elects to early adopt the amendments in this Update in an interim period, the guidance should be applied as of the beginning of the fiscal year that includes that interim period. This Update is not expected to have a significant impact on the Company’s financial statements. In July 2021, the FASB issued ASU 2021-05, Leases (Topic 842), which amends ASC 842 so that lessors are no longer required to recognize a selling loss upon commencement of a lease with variable lease payments that, before the amendments, would have been classified as a sales-type or direct financing lease. Furthermore, a lessor must classify as an operating lease any lease that would otherwise be classified as a sales-type or direct financing lease and that would result in the recognition of a selling loss at lease commencement, provided that the lease includes variable lease payments that do not depend on an index or rate. For public business entities and certain not-for-profit entities and employee benefit plans that have adopted ASC 842, the amendments are effective for fiscal years beginning after December 15, 2021, and for interim periods within those fiscal years. For all other entities that have adopted ASC 842, the amendments are effective for fiscal years beginning after December 15, 2021, and for interim periods within fiscal years beginning after December 15, 2022. All entities that have adopted ASC 842 are permitted to early adopt the amendments in ASU 2021-05. The amendments in ASU 2021-05 are effective as of the same date as the guidance in ASC 842 for entities that have not adopted ASC 842. This Update is not expected to have a significant impact on the Company’s financial statements.
