Accounting Policies [Abstract]
Allowance for Loan Losses	Allowance for Loan Losses: The allowance for loan losses is regularly reviewed by management to determine that the amount is considered adequate to absorb probable losses in the loan portfolio. If not, an additional provision is made to increase the allowance. This evaluation includes specific loss estimates on certain individually reviewed impaired loans, the pooling of commercial credits risk graded as special mention and substandard that are not individually analyzed, and general loss estimates that are based upon the size, quality, and concentration characteristics of the various loan portfolios, adverse situations that may affect a borrower’s ability to repay, and current economic and industry conditions, among other items. Those judgments and assumptions that are most critical to the application of this accounting policy are assessing the initial and on-going credit-worthiness of the borrower, the amount and timing of future cash flows of the borrower that are available for repayment of the loan, the sufficiency of underlying collateral, the enforceability of third-party guarantees, the frequency and subjectivity of loan reviews and risk ratings, emerging or changing trends that might not be fully captured in the historical loss experience, and charges against the allowance for actual losses that are greater than previously estimated. These judgments and assumptions are dependent upon or can be influenced by a variety of factors, including the breadth and depth of experience of lending officers, credit administration and the corporate loan review staff that periodically review the status of the loan, changing economic and industry conditions, changes in the financial condition of the borrower and changes in the value and availability of the underlying collateral and guarantees.
Use of Estimates	Use of Estimates: To prepare financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in financial statements and the disclosures provided, and future results could differ. The allowance for loan losses, consideration of impairment of goodwill, fair values of financial instruments, deferred taxes, swap assets/liabilities and pension obligations are particularly subject to change.
Adoption of New Accounting Standards	Adoption of New Accounting Standards: In October 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-08, Codification Improvements to Subtopic 310-20, Receivables – Nonrefundable Fees and Other Costs, which clarifies that, for each reporting period, an entity should reevaluate whether a callable debt security is within the scope of ASC 310-20-35-33. We adopted ASU 2020-08 effective January 1, 2021, which did not have a material impact on the Company’s Consolidated Financial Statements.
Effect of Newly Issued but Not Yet Effective Accounting Standards	Effect of Newly Issued but Not Yet Effective Accounting Standards: In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which changes the impairment model for most financial assets. This ASU 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 ASU 2016-13 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 effected 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. ASU 2016-13 was to be effective for annual and interim periods beginning after December 15, 2019, with early adoption permitted for annual and interim periods beginning after December 15, 2018. In November 2019, however, the FASB issued ASU 2019-10, Financial Instruments ‒ Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842). This Update deferred the effective date of ASU 2016-13 for U.S. Securities and Exchange Commission (“SEC”) filers that are eligible to be smaller reporting companies, such as the Company, to fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. Management is in the process of evaluating the impact adoption of ASU 2016-13 will have on the Company’s Consolidated Financial Statements. This process has engaged multiple areas of the Company in evaluating loss estimation methods and application of these methods to specific segments of the loan portfolio. Management has been actively monitoring FASB developments and evaluating the use of different methods allowed. Due to continuing development of our methodology, additional time is required to quantify the effect this ASU will have on the Company’s Consolidated Financial Statements. Management plans on running parallel calculations and finalizing a method or methods of adoption in time for the effective date. In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. To simplify the subsequent measurement of goodwill, the FASB eliminated Step 2 from the goodwill impairment test. In computing the implied fair value of goodwill under Step 2, an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, under the amendments in this Update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. A public business entity that is an SEC filer, such as the Company, was to adopt the amendments in this Update for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. In November 2019, however, the FASB issued ASU 2019-10, Financial Instruments ‒ Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842), which deferred the effective date for ASC 350, Intangibles – Goodwill and Other, for smaller reporting companies, such as the Company, to fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations. In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments – Credit Losses, and Topic 825, Financial Instruments, which affects a variety of topics in the Codification and applies to all reporting entities within the scope of the affected accounting guidance. Topic 326, Financial Instruments – Credit Losses amendments are effective for SEC registrants for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The amendments to Topic 825 were to be effective for interim and annual reporting periods beginning after December 15, 2019. In November 2019, however, the FASB issued ASU 2019-10, Financial Instruments ‒ Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842). This Update defers the effective date of ASU 2016-13 for SEC filers that are eligible to be smaller reporting companies, such as the Company, to fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. This Update is not expected to have a material impact on the Company’s financial statements. In May 2019, the FASB issued ASU 2019-05, Financial Instruments – Credit Losses, Topic 326, which allows entities to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost upon adoption of the new credit losses standard. To be eligible for the transition election, the existing financial asset must otherwise be both within the scope of the new credit losses standard and eligible for applying the fair value option in ASC 825-10.3. The election must be applied on an instrument-by-instrument basis and is not available for either available-for-sale or held-to-maturity debt securities. For entities that elect the fair value option, the difference between the carrying amount and the fair value of the financial asset would be recognized through a cumulative-effect adjustment to opening retained earnings as of the date an entity adopted ASU 2016-13. Changes in fair value of that financial asset would subsequently be reported in current earnings. For entities that have not yet adopted ASU 2016-13, the effective dates and transition requirements are the same as those in ASU 2016-13. For entities that have adopted ASU 2016-13, ASU 2019-05 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted once ASU 2016-13 has been adopted. In November 2019, the FASB issued ASU 2019-10, Financial Instruments ‒ Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842). The Update defers the effective date of ASU 2016-13 for SEC filers that are eligible to be smaller reporting companies, such as the Company, to fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial statements. In November 2019, the FASB issued ASU 2019-10, Financial Instruments ‒ Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842). The Update defers the effective dates of ASU 2016-13 for SEC filers that are eligible to be smaller reporting companies, such as the Company, to fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. This Update also amends the mandatory effective date for the elimination of Step 2 from the goodwill impairment test under ASU No. 2017-04, Intangibles ‒ Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (Goodwill), to align with those used for credit losses. Furthermore, the ASU provides a one-year deferral of the effective dates of the ASUs on derivatives and hedging and leases for companies that are not public business entities. The Company qualified as a smaller reporting company and does not expect to early adopt these ASUs. In November 2019, the FASB issued ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments – Credit Losses, to clarify its new credit impairment guidance in ASC 326, based on implementation issues raised by stakeholders. This Update clarified, among other things, that expected recoveries are to be included in the allowance for credit losses for these financial assets; an accounting policy election can be made to adjust the effective interest rate for existing troubled debt restructurings based on the prepayment assumptions instead of the prepayment assumptions applicable immediately prior to the restructuring event; and extends the practical expedient to exclude accrued interest receivable from all additional relevant disclosures involving amortized cost basis. The effective dates in this Update are the same as those applicable for ASU 2019-10. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations. In March 2020, the FASB issued ASU 2020-03, Codification Improvements to Financial Instruments. This ASU was issued to improve and clarify various financial instruments topics, including the current expected credit losses (CECL) standard issued in 2016. The ASU includes seven issues that describe the areas of improvement and the related amendments to GAAP; they are intended to make the standards easier to understand and apply and to eliminate inconsistencies, and they are narrow in scope and are not expected to significantly change practice for most entities. Among its provisions, the ASU clarifies that all entities, other than public business entities that elected the fair value option, are required to provide certain fair value disclosures under ASC 825, Financial Instruments, in both interim and annual financial statements. It also clarifies that the contractual term of a net investment in a lease under Topic 842 should be the contractual term used to measure expected credit losses under Topic 326. Amendments related to ASU 2019-04 are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is not permitted before an entity’s adoption of ASU 2016-01. Amendments related to ASU 2016-13 for entities that have not yet adopted that guidance are effective upon adoption of the amendments in ASU 2016-13. Early adoption is not permitted before an entity’s adoption of ASU 2016-13. Amendments related to ASU 2016-13 for entities that have adopted that guidance are effective for fiscal years beginning after December 15, 2019, including interim periods within those years. Other amendments are effective upon issuance of this ASU. This Update is not expected to have a significant impact on the Company’s financial statements. 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. The Update is designed to provide relief from the accounting analysis and impacts that may otherwise be required for modifications to agreements necessitated by reference rate reform. The Update also provides optional expedients to enable companies to continue to apply hedge accounting to certain hedging relationships impacted by reference rate reform. The amendments in this Update are effective for all entities as of March 12, 2020 through December 31, 2022. The Company is working through this transition via a multi-disciplinary project team. We are still evaluating the impact the change from LIBOR to a benchmark like SOFR or Prime Rate will have on our financial condition, results of operations or cash flows. Other recent ASU’s issued by the FASB did not, or are not believed by management to have, a material effect on the Company’s present or future Consolidated Financial Statements.

A public business entity that is an SEC filer, such as the Company, was to adopt the amendments in this Update for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. In November 2019, however, the FASB issued ASU 2019-10, Financial Instruments ‒ Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842), which deferred the effective date for ASC 350, Intangibles – Goodwill and Other, for smaller reporting companies, such as the Company, to fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations.

In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments – Credit Losses, and Topic 825, Financial Instruments, which affects a variety of topics in the Codification and applies to all reporting entities within the scope of the affected accounting guidance. Topic 326, Financial Instruments – Credit Losses amendments are effective for SEC registrants for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The amendments to Topic 825 were to be effective for interim and annual reporting periods beginning after December 15, 2019. In November 2019, however, the FASB issued ASU 2019-10, Financial Instruments ‒ Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842). This Update defers the effective date of ASU 2016-13 for SEC filers that are eligible to be smaller reporting companies, such as the Company, to fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. This Update is not expected to have a material impact on the Company’s financial statements.

In May 2019, the FASB issued ASU 2019-05, Financial Instruments – Credit Losses, Topic 326, which allows entities to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost upon adoption of the new credit losses standard. To be eligible for the transition election, the existing financial asset must otherwise be both within the scope of the new credit losses standard and eligible for applying the fair value option in ASC 825-10.3. The election must be applied on an instrument-by-instrument basis and is not available for either available-for-sale or held-to-maturity debt securities. For entities that elect the fair value option, the difference between the carrying amount and the fair value of the financial asset would be recognized through a cumulative-effect adjustment to opening retained earnings as of the date an entity adopted ASU 2016-13. Changes in fair value of that financial asset would subsequently be reported in current earnings. For entities that have not yet adopted ASU 2016-13, the effective dates and transition requirements are the same as those in ASU 2016-13. For entities that have adopted ASU 2016-13, ASU 2019-05 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted once ASU 2016-13 has been adopted. In November 2019, the FASB issued ASU 2019-10, Financial Instruments ‒ Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842). The Update defers the effective date of ASU 2016-13 for SEC filers that are eligible to be smaller reporting companies, such as the Company, to fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial statements.

This Update also amends the mandatory effective date for the elimination of Step 2 from the goodwill impairment test under ASU No. 2017-04, Intangibles ‒ Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (Goodwill), to align with those used for credit losses. Furthermore, the ASU provides a one-year deferral of the effective dates of the ASUs on derivatives and hedging and leases for companies that are not public business entities. The Company qualified as a smaller reporting company and does not expect to early adopt these ASUs.

In November 2019, the FASB issued ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments – Credit Losses, to clarify its new credit impairment guidance in ASC 326, based on implementation issues raised by stakeholders. This Update clarified, among other things, that expected recoveries are to be included in the allowance for credit losses for these financial assets; an accounting policy election can be made to adjust the effective interest rate for existing troubled debt restructurings based on the prepayment assumptions instead of the prepayment assumptions applicable immediately prior to the restructuring event; and extends the practical expedient to exclude accrued interest receivable from all additional relevant disclosures involving amortized cost basis.

It also clarifies that the contractual term of a net investment in a lease under Topic 842 should be the contractual term used to measure expected credit losses under Topic 326. Amendments related to ASU 2019-04 are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is not permitted before an entity’s adoption of ASU 2016-01. Amendments related to ASU 2016-13 for entities that have not yet adopted that guidance are effective upon adoption of the amendments in ASU 2016-13. Early adoption is not permitted before an entity’s adoption of ASU 2016-13. Amendments related to ASU 2016-13 for entities that have adopted that guidance are effective for fiscal years beginning after December 15, 2019, including interim

periods within those years. Other amendments are effective upon issuance of this ASU. This Update is not expected to have a significant impact on the Company’s financial statements.

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. The Update is designed to provide relief from the accounting analysis and impacts that may otherwise be required for modifications to agreements necessitated by reference rate reform. The Update also provides optional expedients to enable companies to continue to apply hedge accounting to certain hedging relationships impacted by reference rate reform. The amendments in this Update are effective for all entities as of March 12, 2020 through December 31, 2022. The Company is working through this transition via a multi-disciplinary project team. We are still evaluating the impact the change from LIBOR to a benchmark like SOFR or Prime Rate will have on our financial condition, results of operations or cash flows.

Other recent ASU’s issued by the FASB did not, or are not believed by management to have, a material effect on the Company’s present or future Consolidated Financial Statements.
