Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	General In the opinion of management, all adjustments necessary for a fair presentation of the financial position and results of operations for the periods presented have been included, and all intercompany transactions have been eliminated in consolidation. Results of operations for the three and six months ended June 30, 2023 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2023. The Condensed Consolidated Balance Sheet as of December 31, 2022 has been derived from the audited consolidated financial statements contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, filed with the Securities Exchange Commission (“SEC”) on February 23, 2023 (SEC File No. 001-37497) (the “2022 Form 10-K”). A summary description of the significant accounting policies followed by the Company is set forth in Note 1 of the Notes to Consolidated Financial Statements in the Company’s 2022 Form 10-K. These Unaudited Interim Condensed Consolidated Financial Statements should be read in conjunction with the audited consolidated financial statements and footnotes in the Company's 2022 Form 10-K. The preparation of financial statements in conformity with United States (“US”) generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and the reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from those estimates. Amounts in all tables in the Notes to Unaudited Condensed Consolidated Financial Statements have been presented in thousands, except percentage, time period, share and per share data or where otherwise indicated.
Business Segments	Business SegmentsOperating segments are components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. Management has determined that the Company has two reportable operating segments: Banking and Fintech, as discussed more fully in Note 11. Segments.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In March 2020, the FASB issued Accounting Standards Update (“ASU”) No. 2020-04 “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU 2020-04”). ASU 2020-04 provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. In December 2022, ASU 2022-06 “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848” was issued deferring the sunset date of Topic 848. With the amendments, the ASU can be adopted by the Company as of March 12, 2020, through December 31, 2024. The Company does not believe these standards will have a material impact on its consolidated financial statements. To address the discontinuance of LIBOR, the Company stopped originating variable LIBOR-based loans effective December 31, 2021 and started to negotiate loans using the preferred replacement index, the Secured Overnight Financing Rate (“SOFR”) or a relevant duration U.S. Treasury rate. For currently outstanding LIBOR-based loans, the timing and manner in which each customer’s contract transitions from LIBOR to another rate will vary on a case-by-case basis. As of June 30, 2023, the Company has transitioned nearly all its LIBOR-based loan exposure to an alternative index. The remaining LIBOR-based loans will transition to an alternative index at their next repricing date. In March 2022, the FASB issued ASU No. 2022-02 “Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings (“TDRs”) and Vintage Disclosures” (“ASU 2022-02”). ASU 2022-02 eliminates the accounting guidance for TDRs by creditors in ASC 310-40, Receivables – Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings when a borrower is experiencing financial difficulty. Additionally, for public business entities, ASU 2022-02 requires that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of ASC 326-20, Financial Instruments – Credit Losses – Measured at Amortized Cost. The Company adopted the standard on January 1, 2023 using the modified retrospective method resulting in a net increase to retained earnings of $676 thousand. In June 2022, the FASB issued ASU No. 2022-03 “Fair Value Measurement (Topic 820) Fair Value Measurement of Equity Securities Subject to Contractual Restrictions” (“ASU 2022-03”). ASU 2022-03 indicates a contractual sale restriction on equity securities should not be considered in measuring fair value, however, disclosure should be made about such restrictions. The amendments in this standard will be effective for the Company on January 1, 2024. The Company does not believe this standard will have a material impact on its consolidated financial statements. In March 2023, the 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” (“ASU 2023-02”). ASU 2023-02 permits companies to account for tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. The amendments in this standard will be effective for the Company on January 1, 2024. The Company does not believe this standard will have a material impact on its consolidated financial statements.
Variable Interest Entities	Variable Interest Entities Variable interests are defined as contractual ownership or other interests in an entity that change with fluctuations in the fair value of an entity's net asset value (a “VIE”). The primary beneficiary consolidates the VIE. The primary beneficiary is defined as the enterprise that has both the power to direct the activities of the VIE that most significantly impact the entity's economic performance and the obligation to absorb losses or the right to receive benefits that could be significant to the VIE. Solar Renewable Energy Tax Credit Investments The Company has equity interests in several limited liability companies that own and operate solar renewable energy projects which are accounted for as equity method investments. Over the course of the investments, the Company will receive federal and state tax credits, tax-related benefits, and excess cash available for distribution, if any. The Company may be called to sell its interest in the limited partnerships through a call option once all investment tax credits have been recognized. Affordable Housing The Company has an equity investment in a limited liability company (“LIHTC”) that qualifies as an affordable housing project, managed by an unrelated general partner. The Company accounts for the investment under the proportional amortization method. Under this method an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance as a component of income tax expense. The Company also has equity interests in two limited liability companies that invest in the acquisition, rehabilitation, or new construction of local qualified housing projects which are accounted for as equity method investments. Canapi Funds The Company’s limited partnership investments in the Canapi Funds focus on providing venture capital to new and emerging financial technology companies. After initial commitment and over the course of the investment period, the Company will make capital contributions and receive profit and return of capital distributions as a result of fund performance until the funds wind down. Non-marketable and Other Equity Investments The Company also has limited interests in several non-marketable funds, including Small Business Investment Company (“SBIC”) and venture capital funds, which are accounted for as equity security investments. After the initial commitment and over the course of the investment period, the Company will make capital contributions and receive profit and return of capital distributions as a result of fund performance until the funds wind down. While the partnership agreements allow the Company to remove the general partner, this right is not deemed to be substantive as the general partner can only be removed for cause. All investments are generally non-redeemable and distributions are expected to be received through the liquidation of the underlying investments throughout the life of the investment fund. Investments may only be sold or transferred subject to the notice and approval provisions of the underlying investment agreement. The above investments meet the criteria of a VIE, however, the Company is not the primary beneficiary of the entities, as it does not have the power to direct the activities that most significantly impact the economic performance of the entities. The Company’s investment in the unconsolidated VIEs are carried in other assets and the Company’s unfunded capital and other commitments related to the unconsolidated VIEs are carried in other liabilities on the Unaudited Condensed Consolidated Balance Sheets. The Company’s maximum exposure to loss from unconsolidated VIEs includes the investment recorded on the Company’s Unaudited Condensed Consolidated Balance Sheets. For solar ITC investments, the balance sheet figures are net of any impairment recognized, and includes previously recorded tax credits which remain subject to recapture by taxing authorities based on compliance features required to be met at the project level. While the Company believes the potential for loss from these investments is remote, the maximum exposure for solar tax credit investments was determined by assuming a scenario where related tax credits were recaptured.
