SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
Sep. 30, 2023
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements have been prepared pursuant to rules and regulations of the SEC and in compliance with U.S. generally accepted accounting principles ("GAAP"). Because this report is based on an interim period, certain information and footnote disclosures normally included in the consolidated financial statements prepared in accordance with GAAP have been condensed or omitted.
Use of Estimates	Use of Estimates To prepare financial statements in conformity with GAAP, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the condensed consolidated financial statements and the disclosures provided and future results could differ.
Operating Segments	Operating Segments While the Corporation's chief operating decision makers monitor the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Corporation-wide basis, and operating segments are aggregated into one as operating results for all segments are similar. Accordingly, all of the financial services operations are considered by management to be aggregated in one reportable operating segment.
Goodwill Assessment	Goodwill Assessment The Corporation's policy is to test goodwill for impairment annually on December 31 or on an interim basis if an event triggering impairment may have occurred. During the nine months ended September 30, 2023, the economic uncertainty and market volatility resulting from the rising interest rate environment and the recent banking industry stresses resulted in a decrease in the Corporation's stock price and market capitalization. Management believed such a decrease was a triggering indicator requiring an interim goodwill impairment analysis. At September 30, 2023, the Corporation elected to perform a qualitative assessment to determine if it was more likely than not that the fair value exceeded its carrying value, including goodwill. The qualitative assessment indicated that it was more likely than not that the fair value exceeded its carrying value, resulting in no impairment. Management will continue to evaluate the economic conditions at future reporting periods for any potential applicable changes.
Accounting Standards Adopted and Accounting Pronouncements Pending Adoption	Accounting Standards Adopted in 2022 In December 2022, the Financial Accounting Standards Board (the “FASB”) issued ASU No. 2022-06 - Reference Rate Reform (Topic 848). ASU 2022-06 extends the period of time preparers can utilize the reference rate reform relief guidance provided by ASU 2020-04 and ASU 2021-01, which are discussed above. ASU 2022-06, which was effective upon issuance, defers the sunset date of this prior guidance from December 31, 2022 to December 31, 2024, after which entities will no longer be permitted to apply the relief guidance in Topic 848. ASU 2022-06 did not have a material impact on the Corporation's financial statements and related disclosures. Accounting Standards Adopted in 2023 In October 2021, the FASB issued ASU No. 2021-08, "Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers." This ASU requires that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, "Revenue from Contracts with Customers." ASU 2021-08 was effective for the Corporation on January 1, 2023 and did not have a material impact on its condensed consolidated financial statements and related disclosures. In March 2022, the FASB issued ASU 2022-01, "Derivatives and Hedging (Topic 815): Fair Value Hedging - Portfolio Layer Method." Under prior guidance, entities can apply the last-of-layer hedging method to hedge the exposure of a closed portfolio of prepayable financial assets to fair value changes due to changes in interest rates for a portion of the portfolio that is not expected to be affected by prepayments, defaults, and other events affecting the timing and amount of cash flows. ASU 2022-01 expands the last-of-layer method, which permits only one hedge layer, to allow multiple hedged layers of a single closed portfolio. To reflect that expansion, the last-of-layer method is renamed the portfolio layer method. ASU 2022-01 also (i) expands the scope of the portfolio layer method to include non-prepayable financial assets, (ii) specifies eligible hedging instruments in a single-layer hedge, (iii) provides additional guidance on the accounting for and disclosure of hedge basis adjustments under the portfolio layer method and (iv) specifies how hedge basis adjustments should be considered when determining credit losses for the assets included in the closed portfolio. ASU 2022-01 was effective for the Corporation on January 1, 2023 and did not have a material impact on its condensed consolidated financial statements and related disclosures. In March 2022, the FASB issued ASU No. 2022-02, "Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures." This ASU eliminates the separate recognition and measurement guidance for Troubled Debt Restructurings ("TDRs") by creditors. The elimination of the TDRs guidance may be adopted prospectively for loan modifications after adoption or on a modified retrospective basis, which would also apply to loans previously modified, resulting in a cumulative effect adjustment to retained earnings in the period of adoption for changes in the allowance for credit losses. ASU 2022-02 was effective for the Corporation on January 1, 2023 and did not have a material impact on its condensed consolidated financial statements and related disclosures. In July 2023, FASB issued ASU No. 2023-03, "Presentation of Financial Statements (Topic 205), Income Statement - Reporting Comprehensive Income (Topic 220), Distinguishing Liabilities from Equity (Topic 480), Equity (Topic 505), and Compensation - Stock Compensation (Topic 718): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 120, SEC Staff Announcement at the March 24, 2022 EITF Meeting, and Staff Accounting Bulletin Topic 6.B, Accounting Series Release 280 - General Revision of Regulation S-X: Income or Loss Applicable to Common Stock." This ASU amends the FASB Accounting Standards Codification for SEC updates pursuant to SEC Staff Accounting Bulletin No. 120; SEC Staff Announcement at the March 24, 2022 Emerging Issues Task Force (“EITF”) Meeting; and Staff Accounting Bulletin Topic 6.B, Accounting Series Release 280 - General Revision of Regulation S-X: Income or Loss Applicable to Common Stock. The updates were effective immediately. These updates did not have a material impact on the Corporation's consolidated financial statements and related disclosures. Accounting Pronouncements Pending Adoption In June 2022, FASB issued ASU No. 2022-03, "Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions." In this ASU, a contractual restriction on the sale of an equity security is not considered in measuring the security's fair value. The ASU also requires certain disclosures for equity securities that are subject to contractual restrictions. This guidance is effective for the Corporation on January 1, 2024, with early adoption permitted. The Corporation is evaluating the effect that ASU 2022-03 will have on its consolidated financial statements and related disclosures. In March 2023, FASB issued ASU No. 2023-01, "Leases (Topic 842): Common Control Arrangements." This ASU requires the Corporation to amortize leasehold improvements associated with common control leases over the useful life to the common control group. This guidance is effective for the Corporation on January 1, 2024 with early adoption permitted. The Corporation is evaluating the effect that ASU 2023-01 will have on its consolidated financial statements and related disclosures. In March 2023, FASB issued ASU No. 2023-02, "Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method." In this ASU, these amendments allow the Corporation to elect to account for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. This guidance is effective for the Corporation on January 1, 2024 with early adoption permitted. The Corporation is evaluating the effect that ASU 2023-02 will have on its consolidated financial statements and related disclosures. In August 2023, FASB issued ASU No. 2023-05, "Business Combinations - Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement." ASU 2023-05 requires certain joint ventures to apply a new basis of accounting upon formation by recognizing and initially measuring most of their assets and liabilities at fair value. The objectives of the amendments are to provide decision-useful information to investors and other allocators of capital in a joint venture’s financial statements and also to reduce diversity in practice. ASU 2023-05 should be applied prospectively and is effective for all newly formed joint venture entities with a formation date on or after January 1, 2025. Early adoption is permitted, and joint ventures formed prior to the adoption date may elect to apply the new guidance retrospectively back to their original formation date. The Corporation is evaluating the effect that ASU 2023-05 will have on its consolidated financial statements and related disclosures. In October 2023, FASB issued ASU No. 2023-06, "Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative." The ASU amends the ASC to incorporate certain disclosure requirements from SEC Release No. 33-10532 - Disclosure Update and Simplification that was issued in 2018. The effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. The Corporation is evaluating the effect that ASU 2023-06 will have on its consolidated financial statements and related disclosures.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

9 Months Ended

Sep. 30, 2023

Organization, Consolidation and Presentation of Financial Statements [Abstract]

The accompanying condensed consolidated financial statements have been prepared pursuant to rules and regulations of the SEC and in compliance with U.S. generally accepted accounting principles ("GAAP"). Because this report is based on an interim period, certain information and footnote disclosures normally included in the consolidated financial statements prepared in accordance with GAAP have been condensed or omitted.

Use of Estimates

To prepare financial statements in conformity with GAAP, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the condensed consolidated financial statements and the disclosures provided and future results could differ.

Operating Segments

While the Corporation's chief operating decision makers monitor the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Corporation-wide basis, and operating segments are aggregated into one as operating results for all segments are similar. Accordingly, all of the financial services operations are considered by management to be aggregated in one reportable operating segment.

Goodwill Assessment

The Corporation's policy is to test goodwill for impairment annually on December 31 or on an interim basis if an event triggering impairment may have occurred. During the nine months ended September 30, 2023, the economic uncertainty and market volatility resulting from the rising interest rate environment and the recent banking industry stresses resulted in a decrease in the Corporation's stock price and market capitalization. Management believed such a decrease was a triggering indicator requiring an interim goodwill impairment analysis. At September 30, 2023, the Corporation elected to perform a qualitative assessment to determine if it was more likely than not that the fair value exceeded its carrying value, including goodwill. The qualitative assessment indicated that it was more likely than not that the fair value exceeded its carrying value, resulting in no impairment. Management will continue to evaluate the economic conditions at future reporting periods for any potential applicable changes.
