ASU 2022-02 eliminated the concept of troubled debt restructurings and introduced broader modification reporting requirements. Previously, troubled debt restructurings included any type of modification that included a below market concession which was granted both to a borrower in financial difficulty and as a result of financial difficulty. Loan modifications made to borrowers experiencing financial difficulty no longer consider whether a market concession has been granted, as was required with troubled debt restructurings, but rather includes as modifications within the four listed reportable modification types to a borrower deemed to be experiencing financial difficulty. An assessment of whether a borrower is experiencing financial difficulty is made on the date of the modification. Loans reported in this classification have a rating of substandard or worse, and may include both accruing and nonaccruing loans. Loans are assessed to determine whether the modification constitutes a new loan or a continuation of the existing loan. Depending on the terms of the modification and nature of the borrower, this may result in a downgrade or placing a loan on nonaccrual status, which in turn would impact the loan's classification within the ALLL. Because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses because of the measurement methodologies used to estimate the allowance, a change to the allowance for credit losses is generally not recorded upon modification.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-indent:13.5pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Business Segments</span></div><div style="margin-bottom:6pt;text-indent:22.5pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We regularly assess our strategic plans, operations, reporting structures and financial information provided to management to identify our reportable segments. Civic, a lending subsidiary we acquired in February 2021, has historically been identified as an operating segment. In the fourth quarter of 2022, Civic met a quantitative threshold which required it to be disclosed as a reportable operating segment. Therefore, we had two reportable operating segments as of December 31, 2022: Commercial Banking and Civic, and a third segment, Other, which was used for inter-segment eliminations. In the first quarter of 2023, we began a restructuring of Civic which included removing most of Civic's top management and transferring day-to-day management of most of Civic's operating functions to managers at the Bank. Due to the restructuring of Civic, discrete financial information is no longer prepared. Our management reporting captures the direct expenses of Civic, however, none of the expenses now being incurred to manage Civic are being directly charged or allocated to Civic. Therefore, it is no longer feasible to produce meaningful, separate full financial statements, and thus, discrete financial information for Civic is no longer prepared or distributed to our chief operating decision maker. Thus, Civic no longer meets the criteria to be considered a reportable operating segment as of March 31, 2023. We sold the Civic business in the second quarter of 2023, and we are retaining and servicing the Civic loans on our balance sheet. At September 30, 2023, June 30, 2023, and March 31, 2023, we operated as one reportable segment - Commercial Banking. </span></div><div style="margin-bottom:6pt;margin-top:12pt;text-indent:13.5pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Accounting Standards Adopted in 2023 </span><span style="color:#ff0000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"> </span></div><div style="margin-bottom:6pt;text-indent:22.5pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Effective January 1, 2023, we completed the adoption of ASU 2022-02, </span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">“Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures,"</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"> by eliminating the accounting guidance for TDRs by creditors, in ASC 310-40, "</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Receivables – Troubled Debt Restructurings by Creditors," </span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">while enhancing disclosure requirements for restructurings involving borrowers that are experiencing financial difficulty.
