Recent Accounting and Regulatory Pronouncements

Accounting Standards Adopted

The Company adopted ASU 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method effective January 1, 2024, and changed the accounting method of its LIHTC structured investments from the equity method to the proportional amortization method. The Company adopted ASU 2023-02 using the modified retrospective approach. Under this adoption approach, management was required to verify the LIHTCs met the conditions for proportional amortization method as of the date the investments were originally made by the Bank. In addition, management evaluated the actual tax credits and other income tax benefits received, as well as the remaining benefits expected to be received, as of the adoption date. The cumulative difference between the equity method and proportional amortization method resulted in a one-time cumulative effect adjustment recorded through retained earnings as of January 1, 2024. The cumulative effect resulting from the adoption of proportional amortization method was a net reduction to retained earnings of $10.2 million.

​

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, to improve disclosures about a public entity’s reportable segments and address requests from investors and other allocators of capital for additional, more detailed information about a reportable segment’s expenses. Segment information gives investors an understanding of overall performance and is key to assessing potential future cash flows. In addition, although information about a segment’s revenue and measure of profit or loss is disclosed in an entity’s financial statements, there is limited information disclosed about a segment’s expenses. The key amendments include annual and interim disclosures of significant expenses and other segment items that are regularly provided to the chief operating decision maker and included within each reported measure of profit or loss, as well as any other key measure of performance used for segment management decisions. This ASU also requires disclosure of key profitability measures used in assessing performance and how to allocate resources. The amendments in this ASU are effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company adopted ASU 2023-07 using the retrospective approach. Aside from the new disclosures required by ASU No. 2023-07, the ASU did not have a material impact on our consolidated financial statements. See Note 29—Segment Reporting for further disclosure.

​

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which aims to address requests for improved income tax disclosures from investors, lenders, creditors and other allocators of capital (collectively, “investors”) that use the financial statements to make capital allocation decisions. The amendments in this ASU address investor requests for more transparency about income tax information, including jurisdictional information, by requiring consistent categories and greater disaggregation of information in both the rate reconciliation and income taxes paid disaggregated by jurisdiction. The amendments are effective for annual periods beginning after December 15, 2024. The adoption of this ASU did not have a material impact on its financial statements beyond the additional required disclosures.

Issued But Not Yet Adopted Accounting Standards

In December 2026, the FASB issued Accounting Standards Update (ASU) No. 2025‑08, Financial Instruments—Credit Losses (Topic 326): Purchased Loans, which expands the population of acquired financial assets subject to the gross‑up approach for accounting for credit losses. This ASU introduces the concept of purchased seasoned loans and requires certain acquired loans (excluding credit cards) that have not experienced significant credit deterioration since origination to be accounted for using the gross‑up approach, addressing longstanding stakeholder concerns regarding the complexity and reduced comparability under previous guidance that distinguished between PCD and non‑PCD assets. The amendments clarify initial and subsequent measurement, including recognition of an allowance for credit losses at acquisition with an offsetting gross‑up to the purchase price, and require purchased seasoned loans to follow the same interest income recognition model as originated financial assets. The ASU also updates disclosure requirements to include separate presentation of the initial allowance recognized for purchased seasoned loans. The amendments are effective for annual reporting periods beginning after December 15, 2026, and for interim reporting periods within those annual periods, with early adoption permitted. The amendments must be applied prospectively to loans acquired on or after the adoption date. In the event of future acquisitions, this ASU will likely have a material impact on the Company’s financial statements.

​

In September 2025, the FASB issued Accounting Standards Update (ASU) No. 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, seeking to update the guidance on accounting for software. This ASU addresses stakeholder and investor concerns on the challenges of applying current internal-use software accounting requirements that do not specifically address software developed using modern incremental and iterative methods, which has led to diversity in practice in determining when to begin capitalizing software costs. The ASU removes all references to a prescriptive and sequential software development method. The amendments require an entity to start capitalizing software costs when management has authorized and committed to funding the software project, and it is probable that the project will be completed and the software will be used to perform the function intended. The amendments in the ASU are effective for annual reporting periods beginning after December 15, 2027, and for interim reporting periods beginning after December 15, 2027. The Company does not anticipate this ASU will have a material impact on its financial statements.

​

In November 2024, the FASB has issued Accounting Standards Update ASU No. 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, to provide investors with more decision-useful information about a public business entity’s expense by improving disclosures on income statement expenses. The amendments in the ASU are effective for public business entities only for annual reporting periods beginning after December 15, 2026, and for interim reporting periods beginning after December 15, 2027. The Company does not anticipate this ASU will have a material impact on its financial statements.
