Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	GENERAL Financial Statement Preparation The significant accounting policies followed by the Corporation and its wholly-owned subsidiaries for interim financial reporting are consistent with the accounting policies followed for annual financial reporting. All adjustments, which are of a normal recurring nature and are in the opinion of management necessary for a fair statement of the results for the periods reported, have been included in the accompanying Consolidated Condensed Financial Statements. The Consolidated Condensed Balance Sheet of the Corporation as of December 31, 2019, has been derived from the audited consolidated balance sheet of the Corporation as of that date. Certain information and note disclosures normally included in the Corporation’s annual financial statements, prepared in accordance with accounting principles generally accepted in the United States of America, have been condensed or omitted. These consolidated condensed financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2019 filed with the Securities and Exchange Commission. The results of operations for the three and nine months ended September 30, 2020, are not necessarily indicative of the results to be expected for the year. Reclassifications have been made to prior financial statements to conform to the current financial statement presentation. These reclassifications had no effect on net income. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses and fair value of financial instruments. The uncertainties related to the coronavirus disease 2019 ("COVID-19") could cause significant changes to these estimates compared to what was known at the time these financial statements were prepared. Impact of COVID-19 On January 30, 2020, the World Health Organization (“WHO”) announced that the outbreak of COVID-19 constituted a public health emergency of international concern. On March 11, 2020, WHO declared COVID-19 to be a global pandemic and, on March 13, 2020, the President of the United States declared the COVID-19 outbreak a national emergency. The health concerns relating to the COVID-19 outbreak and related governmental actions taken to reduce the spread of the virus have significantly impacted the global economy (including the states and local economies in which the Corporation operates), disrupted supply chains, lowered equity market valuations, and created significant volatility and disruption in financial markets. The outbreak has resulted in authorities implementing numerous measures to try to contain the virus, such as travel bans and restrictions, quarantines, shelter in place or total lock-down orders and business limitations and shutdowns. As a result of the shelter in place mandates in effect early in the second quarter of 2020, commercial activity throughout our geographic footprint, as well as nationally, decreased significantly during 2020. Most states have reopened, albeit under limited capacities and under other social distancing restrictions; however, commercial activity has not returned to the levels existing prior to the outbreak of the pandemic. Such measures have significantly contributed to rising unemployment and negatively impacted consumer and business spending. As a result, the demand for the Corporation’s products and services has been, and will continue to be, significantly impacted. Recent Accounting Changes Adopted in 2020 FASB Accounting Standards Updates No. 2018-15 - Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract Summary - The FASB issued Accounting Standards Update (ASU) No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which reduces complexity for the accounting for costs of implementing a cloud computing service arrangement. This standard aligns the accounting for implementation costs of hosting arrangements, regardless of whether they convey a license to the hosted software. The ASU aligns the following requirements for capitalizing implementation costs: •Those incurred in a hosting arrangement that is a service contract, and •Those incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). For calendar-year public companies, the changes were effective for fiscal years beginning after December 15, 2019. The Corporation adopted the standard in the first quarter of 2020 and adoption of the standard did not have a significant effect on the Corporation’s consolidated financial statements. FASB Accounting Standards Updates No. 2018-14 - Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans Summary - The FASB issued ASU No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans, that applies to all employers that sponsor defined benefit pension or other postretirement plans. The amendments modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. Disclosure Requirements Deleted •The amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year. •The amount and timing of plan assets expected to be returned to the employer. •Related party disclosures about the amount of future annual benefits covered by insurance and annuity contracts and significant transactions between the employer or related parties and the plan. •For public entities, the effects of a one-percentage-point change in assumed health care cost trend rates on the (a) aggregate of the service and interest cost components of net periodic benefit costs and (b) benefit obligation for postretirement health care benefits. Disclosure Requirements Added •An explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. The amendments also clarify the disclosure requirements in paragraph 715-20-50-3, which state that the following information for defined benefit pension plans should be disclosed: •The projected benefit obligation (PBO) and fair value of plan assets for plans with PBOs in excess of plan assets, and •The accumulated benefit obligation (ABO) and fair value of plan assets for plans with ABOs in excess of plan assets. ASU No. 2018-14 is effective for fiscal years ending after December 15, 2020, for public business entities and for fiscal years ending after December 15, 2021, for all other entities. Early adoption is permitted for all entities. The Corporation adopted the standard in the first quarter of 2020 and adoption of the standard did not have a significant effect on the Corporation’s consolidated financial statements. FASB Accounting Standards Updates No. 2018-13 - Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement Summary - The FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. ASU No. 2018-13 modifies the disclosure requirements on fair value measurements in Topic 820. Certain disclosure requirements related to transfers between Level 1 and Level 2 of the fair value hierarchy and Level 3 valuation process were removed from Topic 820. Disclosures were also added to Topic 820 for changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. In addition, the amendments eliminate "at a minimum" from the phrase “an entity shall disclose at a minimum” to promote the appropriate exercise of discretion by entities when considering fair value measurement disclosures and to clarify that materiality is an appropriate consideration of entities and their auditors when evaluating disclosure requirements. The amendments in ASU No. 2018-13 were effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty were applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments were applied retrospectively to all periods presented upon their effective date. Early adoption was permitted. An entity was permitted to early adopt any removed or modified disclosures upon issuance of ASU No. 2018-13 and delay adoption of the additional disclosures until their effective date. The Corporation adopted the standard in the first quarter of 2020 and adoption of the standard did not have a significant effect on the Corporation’s disclosures. FASB Accounting Standards Updates No. 2017-04 - Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. Summary - The FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill, which simplifies how an entity is required to test goodwill for impairment. To simplify the subsequent measurement of goodwill, the ASU eliminates Step 2 from the goodwill impairment test. The annual, or interim, goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized 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. In addition, the income tax effects of tax deductible goodwill on the carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. The amendments also eliminate the requirements for any reporting unit with a zero or negative carrying amount to perform Step 2 of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the qualitative impairment test is necessary. The amendments were applied on a prospective basis. The Corporation adopted ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill, January 1, 2020 and assessed the recent economic impact and market conditions from the COVID-19 pandemic. At September 30, 2020, the Corporation performed a goodwill impairment test which included various valuation considerations including comparable peer data, precedent transaction comparables, discounted cash flow analysis, overall financial performance, share price of the Corporation's common stock and other factors. The testing resulted in a conclusion that it was not more likely than not that the fair value of the Corporation had declined below its carrying value; therefore, goodwill was not impaired at September 30, 2020. Goodwill assessments are highly sensitive to economic projections and the related assumptions used by management. In the event of a prolonged economic downturn or further deterioration in the economic outlook, continued assessments of our goodwill balance will likely be required in future periods. Details of the goodwill impairment test are included in NOTE 6. GOODWILL of these Notes to Consolidated Condensed Financial Statements. Guidance on Non-TDR Loan Modifications due to COVID-19 On March 22, 2020, a statement was issued by the Bank's banking regulators and titled the “Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus” (the "Interagency Statement") that encourages financial institutions to work prudently with borrowers who are or may be unable to meet their contractual payment obligations due to the effects of COVID-19. Additionally, Section 4013 of the CARES Act further provides that a qualified loan modification is exempt by law from classification as a troubled debt restructure as defined by GAAP, from the period beginning March 1, 2020 until the earlier of December 31, 2020 or the date that is 60 days after the date on which the national emergency concerning the COVID-19 outbreak under the National Emergencies Act (50 U.S.C. 1601 et seq.) terminates. The Interagency Statement was subsequently revised on April 7, 2020 to clarify the interaction of the original guidance with Section 4013 of the CARES Act, as well as setting forth the banking regulators’ views on consumer protection considerations. In accordance with such guidance, the Bank has offered short-term modifications made in response to COVID-19 to borrowers who were current and otherwise not past due. These included short-term, 180 days or less, modifications in the form of payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant. As of September 30, 2020, approximately $176 million of loan balances remained in deferral. Details of the Corporation's modifications are included in the "LOAN QUALITY/PROVISION FOR LOAN LOSSES" section of Management's Discussion and Analysis of Financial Condition and Results of Operations of this Form 10-Q. New Accounting Pronouncements Not Yet Adopted The Corporation continually monitors potential accounting changes and pronouncements. The following pronouncements have been deemed to have the most applicability to the Corporation's financial statements: FASB Accounting Standards Update No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments Summary - The FASB issued Accounting Standards Update (ASU) No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This new guidance was issued to address concerns that current generally accepted accounting principles (GAAP) restricts the ability to record credit losses that are expected, but do not yet meet the “probable” threshold by replacing the current “incurred loss” model for recognizing credit losses with an “expected life of loan loss” model referred to as the Current Expected Credit Loss (CECL) model. Under the CECL model, certain financial assets carried at amortized cost, such as loans held for investment and held-to-maturity debt securities, are required to be presented at the net amount expected to be collected. The measurement of expected credit losses is to be based on information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. This measurement will take place at the time the financial asset is first added to the balance sheet and periodically thereafter. This differs significantly from the “incurred loss” model required under current GAAP, which delays recognition until it is probable a loss has been incurred. The change could materially affect how the allowance for loan losses is determined and cause a charge/credit to earnings through the provision for loan losses. Such could create volatility in earnings and could adversely affect the financial condition of the Corporation. The ASU is effective for SEC filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Pursuant to the CARES Act and the related joint statement of federal banking regulators (which also became effective as of March 27, 2020), and consistent with guidance from the SEC and FASB, the Corporation has elected to delay implementation of ASU No. 2016-13, which would have become effective for the Corporation as of January 1, 2020. As discussed above, ASU No. 2016-13 provides for the replacement of the incurred loss model for recording the allowance for loan losses with CECL. However, as a result of the Corporation’s election, its first, second and third quarter 2020 financial statements have been prepared under the existing incurred loss model. As the temporary relief applicable to the Corporation’s compliance with CECL will end no later than December 31, 2020, the Corporation will implement CECL during the fourth quarter of 2020. The Corporation has developed models that satisfy the requirements of the new standard which will be governed by a system of internal controls and a cross-functional working group consisting of accounting, finance, and credit administration personnel. The loan portfolio was pooled into ten loan segments with similar risk characteristics for which the probability of default/loss given default methodology will be applied. The Corporation intends to utilize a one-year economic forecast period then revert to historical macroeconomic levels for the remaining life of the portfolio. A baseline macroeconomic scenario, along with other scenarios, will be used to develop a range of estimated credit losses for which to determine the best estimate within. The Corporation will record a one-time cumulative-effect adjustment to retained earnings, net of income taxes, on the consolidated balance sheet as of the beginning of the adoption period. If adopted with retrospective measurement to January 1, 2020, the allowance will increase by 55-65 percent from December 31, 2019 because it will cover expected credit losses over the life of the loan portfolio, which approximates four years, and it includes all purchased loans that were previously excluded from the allowance for loan losses calculation. CECL also requires the establishment of a reserve for potential losses from unfunded commitments that is recorded in other liabilities, separate from allowance for credit losses, which is estimated to be approximately $18 million. FASB Accounting Standards Update No. 2019-11 - Codification Improvements to (Topic 326): Financial Instruments - Credit Losses Summary - The FASB issued ASU No. 2019-11, Codification Improvements to Topic 326, Financial Instruments - Credit Losses in order to address issues raised by stakeholders during the implementation of ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses of Financial Instruments. Among other narrow-scope improvements, the new ASU clarifies guidance around how to report expected recoveries. “Expected recoveries” describes a situation in which an organization recognizes a full or partial write-off of the amortized cost basis of a financial asset, but then later determines that the amount written off, or a portion of that amount, will in fact be recovered. While applying the credit losses standard, stakeholders questioned whether expected recoveries were permitted on assets that had already shown credit deterioration at the time of purchase (also known as PCD assets). In response to this question, the ASU permits organizations to record expected recoveries on PCD assets. In addition to other narrow technical improvements, the ASU also reinforces existing guidance that prohibits organizations from recording negative allowances for available-for-sale debt securities. The ASU includes effective dates and transition requirements that vary depending on whether or not an entity has already adopted ASU No. 2016-13. As discussed above, pursuant to the CARES Act, the Corporation elected to defer the adoption of CECL. As the temporary relief applicable to the Corporation’s compliance with CECL will end no later than December 31, 2020, the Corporation will implement CECL during the fourth quarter of 2020. FASB Accounting Standards Updates - No. 2020-04 - Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting Summary - The FASB issued ASU No. 2020-04 to provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. LIBOR and other interbank offered rates are widely used benchmarks or reference rates in the United States and globally. Trillions of dollars in loans, derivatives, and other financial contracts reference LIBOR, the benchmark interest rate banks use to make short-term loans to each other. With global capital markets expected to move away from LIBOR and other interbank offered rates and move toward rates that are more observable or transaction based and 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. The ASU is intended to help stakeholders during the global market-wide reference rate transition period. Entities may apply this ASU as of the beginning of an interim period that includes the March 12, 2020 issuance date of the ASU, through December 31, 2022. The Corporation expects to adopt the practical expedients included in the ASU prior to December 31, 2022. The Corporation is implementing a transition plan to identify and modify its loans and other financial instruments with attributes that are either directly or indirectly influenced by LIBOR. The Corporation is assessing ASU 2020-04 and its impact on the Corporation's transition away from LIBOR for its loans and other financial instruments.

The significant accounting policies followed by the Corporation and its wholly-owned subsidiaries for interim financial reporting are consistent with the accounting policies followed for annual financial reporting. All adjustments, which are of a normal recurring nature and are in the opinion of management necessary for a fair statement of the results for the periods reported, have been included in the accompanying Consolidated Condensed Financial Statements.

The Consolidated Condensed Balance Sheet of the Corporation as of December 31, 2019, has been derived from the audited consolidated balance sheet of the Corporation as of that date. Certain information and note disclosures normally included in the Corporation’s annual financial statements, prepared in accordance with accounting principles generally accepted in the United States of America, have been condensed or omitted. These consolidated condensed financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2019 filed with the Securities and Exchange Commission. The results of operations for the three and nine months ended September 30, 2020, are not necessarily indicative of the results to be expected for the year. Reclassifications have been made to prior financial statements to conform to the current financial statement presentation. These reclassifications had no effect on net income. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses and fair value of financial instruments. The uncertainties related to the coronavirus disease 2019 ("COVID-19") could cause significant changes to these estimates compared to what was known at the time these financial statements were prepared.

On January 30, 2020, the World Health Organization (“WHO”) announced that the outbreak of COVID-19 constituted a public health emergency of international concern. On March 11, 2020, WHO declared COVID-19 to be a global pandemic and, on March 13, 2020, the President of the United States declared the COVID-19 outbreak a national emergency. The health concerns relating to the COVID-19 outbreak and related governmental actions taken to reduce the spread of the virus have significantly impacted the global economy (including the states and local economies in which the Corporation operates), disrupted supply chains, lowered equity market valuations, and created significant volatility and disruption in financial markets. The outbreak has resulted in authorities implementing numerous measures to try to contain the virus, such as travel bans and restrictions, quarantines, shelter in place or total lock-down orders and business limitations and shutdowns. As a result of the shelter in place mandates in effect early in the second quarter of 2020, commercial activity throughout our geographic footprint, as well as nationally, decreased significantly during 2020. Most states have reopened, albeit under limited capacities and under other social distancing restrictions; however, commercial activity has not returned to the levels existing prior to the outbreak of the pandemic. Such measures have significantly contributed to rising unemployment and negatively impacted consumer and business spending. As a result, the demand for the Corporation’s products and services has been, and will continue to be, significantly impacted.

Summary - The FASB issued ASU No. 2020-04 to provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. LIBOR and other interbank offered rates are widely used benchmarks or reference rates in the United States and globally. Trillions of dollars in loans, derivatives, and other financial contracts reference LIBOR, the benchmark interest rate banks use to make short-term loans to each other. With global capital markets expected to move away from LIBOR and other interbank offered rates and move toward rates that are more observable or transaction based and 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. The ASU is intended to help stakeholders during the global market-wide reference rate transition period.

Entities may apply this ASU as of the beginning of an interim period that includes the March 12, 2020 issuance date of the ASU, through December 31, 2022. The Corporation expects to adopt the practical expedients included in the ASU prior to December 31, 2022. The Corporation is implementing a transition plan to identify and modify its loans and other financial instruments with attributes that are either directly or indirectly influenced by LIBOR. The Corporation is assessing ASU 2020-04 and its impact on the Corporation's transition away from LIBOR for its loans and other financial instruments.
