(1)Balances of accrued interest receivable excluded from amortized cost and the calculation of allowance for credit losses amounted to $59.3 million and $52.7 million as of March 31, 2024 and March 31, 2023, respectively.

The balance of allowance for credit losses increased to $146.9 million as of March 31, 2024 compared to $142.2 million at December 31, 2023, driven primarily by specific reserve allocations as well as net loan growth during the three months ended March 31, 2024.

For the purpose of estimating the allowance for credit losses, management segregated the loan portfolio into the portfolio segments detailed in the above tables.  Each of these loan categories possesses unique risk characteristics that are considered when determining the appropriate level of allowance for each segment.  Some of the characteristics unique to each loan category include:

Commercial Portfolio

•Commercial and Industrial: Consists of revolving, nonrevolving, and term loan obligations extended to business and corporate enterprises for the purpose of financing working capital and/or capital investment.  Collateral generally consists of accounts receivable, inventory, plant and equipment, real estate, or other business assets. The primary source of repayment is operating cash flow and, secondarily, liquidation of assets.

•Commercial Real Estate: Consists of mortgage loans to finance investment in real property such as multi-family residential, commercial/retail, office, industrial, hotels, educational and healthcare facilities, as well as other specific use properties and is inclusive of owner-occupied commercial properties.  Loans are typically written with amortizing payment structures.  Collateral values are determined based upon third party appraisals and evaluations.  Permissible loan to value ratios at origination are governed by Company policy and regulatory guidelines. The primary source of repayment is cash flow from operating leases and rents and, secondarily, liquidation of assets.

•Commercial Construction: Consists of short-term construction loans, revolving and nonrevolving credit lines and construction/permanent loans to finance the acquisition, development and construction or rehabilitation of real property. 

Project types include residential land development, one-to-four family, condominium, and multi-family home construction, commercial/retail, office, industrial, hotels, educational and healthcare facilities as well as other specific use properties.  Loans may be written with non-amortizing or hybrid payment structures depending upon the type of project.  Collateral values are determined based upon third party appraisals and evaluations.  Permissible loan to value ratios at origination are governed by Company policy and regulatory guidelines.  Repayment sources vary depending upon the type of project and may consist of proceeds from the sale or lease of units, operating cash flows or liquidation of other assets.

•Small Business: Consists of revolving, term loan and mortgage obligations extended to sole proprietors and small businesses for purposes of financing working capital and/or capital investment.  Collateral generally consists of pledges of business assets including, but not limited to, accounts receivable, inventory, plant and equipment, or real estate if applicable.  The primary source of repayment is operating cash flows and, secondarily, liquidation of assets.

For the commercial portfolio the Company typically obtains personal guarantees for payment from individuals holding material ownership interests in the borrowing entities.

Consumer Portfolio

•Residential Real Estate: Residential mortgage loans held in the Company’s portfolio are made to borrowers who demonstrate the ability to make scheduled payments with full consideration to underwriting factors such as current and expected income, employment status, current assets, other financial resources, credit history and the value of the collateral.  Collateral consists of mortgage liens on one-to-four family residential properties.  Residential mortgage loans also include loans to construct owner-occupied one-to-four family residential properties.

•Home Equity: Home equity loans and credit lines are made to qualified individuals and are primarily secured by senior or junior mortgage liens on one-to-four family homes, condominiums or vacation homes. Each home equity loan has a fixed rate and is billed in equal payments comprised of principal and interest. The majority of home equity lines of credit have a variable rate and are billed in interest-only payments during the draw period. At the end of the draw period, the home equity line of credit is billed as a percentage of the then outstanding principal balance plus all accrued interest over a predetermined repayment period, as set forth in the note. Additionally, the Company has the option of renewing each line of credit for additional draw periods.  Borrower qualifications include favorable credit history combined with supportive income requirements and combined loan to value ratios within established policy guidelines.

•Other Consumer: Other consumer loan products include personal lines of credit and amortizing loans made to qualified individuals for various purposes such as debt consolidation, personal expenses or overdraft protection.  Borrower qualifications include favorable credit history combined with supportive income and collateral requirements within established policy guidelines.  These loans may be secured or unsecured.

Credit Quality

The Company continually monitors the asset quality of the loan portfolio using all available information. Based on this information, loans demonstrating certain payment issues or other weaknesses may be categorized as adversely risk-rated, delinquent, nonperforming and/or put on nonaccrual status. Additionally, in the course of resolving such loans, the Company may choose to modify the contractual terms of certain loans to match the borrower’s ability to repay the loan based on their current financial condition.

The Company reviews numerous credit quality indicators when assessing the risk in its loan portfolio. For the commercial portfolio, the Company utilizes a 10-point credit risk-rating system, which assigns a risk-grade to each loan obligation based on a number of quantitative and qualitative factors associated with a commercial or small business loan transaction. Factors considered include industry and market conditions, position within the industry, earnings trends, operating cash flow, asset/liability values, debt capacity, guarantor strength, management and controls, financial reporting, collateral, and other considerations. The risk-rating categories for the commercial portfolio are defined as follows:

•Pass: Risk-rating “1” through “6” comprises loans ranging from ‘Substantially Risk Free’ which indicates borrowers are of unquestioned credit standing and the pinnacle of credit quality, well established companies with a very strong financial condition, and loans fully secured by cash collateral, through ‘Acceptable Risk,’ which indicates borrowers may exhibit declining earnings, strained cash flow, increasing or above average leverage and/or weakening market fundamentals that indicate below average asset quality, margins and market share. Collateral coverage is protective.

•Special Mention: Borrowers exhibit potential credit weaknesses or downward trends deserving management’s close attention. If not checked or corrected, these trends will weaken the Company’s asset and position. While potentially weak, currently these borrowers are marginally acceptable; no loss of principal or interest is envisioned.

•Substandard: Borrowers exhibit well defined weaknesses that jeopardize the orderly liquidation of debt. Loans may be inadequately protected by the current net worth and paying capacity of the obligor or by the collateral pledged, if any. Normal repayment from the borrower is in jeopardy, although no loss of principal is envisioned. However, there is a distinct possibility that a partial loss of interest and/or principal will occur if the deficiencies are not corrected. Collateral coverage may be inadequate to cover the principal obligation.

•Doubtful: Borrowers exhibit well defined weaknesses that jeopardize the orderly liquidation of debt with the added provision that the weaknesses make collection of the debt in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Serious problems exist to the point where partial loss of principal is likely.

•Loss: Borrowers deemed incapable of repayment. Loans to such borrowers are considered uncollectible and of such little value that continuation as active assets of the Company is not warranted.

The Company utilizes a comprehensive, continuous strategy for evaluating and monitoring commercial credit quality. Initially, credit quality is determined at loan origination and is re-evaluated when subsequent actions, such as renewals, modifications or reviews, occur. Actively managed commercial borrowers are required to provide updated financial information at least annually which is carefully evaluated for any changes in credit quality. Larger loan relationships are subject to a full annual credit review by experienced credit professionals, while continuous portfolio monitoring techniques are employed to evaluate changes in credit quality for smaller loan relationships. Any changes in credit quality are reflected in risk-rating changes. Additionally, the Company retains an independent loan review firm to evaluate the credit quality of the commercial loan portfolio. The independent loan review process achieves significant penetration into the commercial loan portfolio and reports the results of these reviews to the Audit Committee of the Board of Directors on a quarterly basis.

For the Company’s consumer portfolio, the quality of the loan is best indicated by the repayment performance of an individual borrower. As a result, for this portfolio the Company utilizes a pass/default risk-rating system, based on an age analysis (i.e., days past due) associated with each consumer loan. Under this structure, consumer loans less than 90 days past due are assigned a "pass" rating, while any consumer loans 90 days or more past due are assigned a "default" rating.

(1)Loan origination dates in the tables above reflect the original origination date, or the date of a material modification of a previously originated loan.

(2)Other consumer portfolio is inclusive of deposit account overdrafts recorded as loan balances and the associated gross write-offs.

    For the Company’s consumer portfolio, the quality of the loan is best indicated by the repayment performance of an individual borrower. However, the Company does supplement performance data with current Fair Isaac Corporation (“FICO”) scores and Loan to Value (“LTV”) estimates. Current FICO data is purchased and appended to all consumer loans on a regular basis. In addition, automated valuation services and broker opinions of value are used to supplement original value data for the residential real estate and home equity portfolios, periodically. The following table shows the weighted average FICO scores and the weighted average combined LTV ratios at the dates indicated below:

	March 31 2024		December 31 2023
Residential real estate portfolio
FICO score (re-scored)(1)	755		754
LTV (re-valued)(2)	59.7	%	59.8	%
Home equity portfolio
FICO score (re-scored)(1)	770		770

Unfunded Commitments

Management evaluates the need for a reserve on unfunded lending commitments in a manner consistent with loans held for investment. At March 31, 2024 and December 31, 2023, the Company's estimated reserve for unfunded commitments amounted to $1.5 million and $1.3 million, respectively.

Asset Quality

The Company’s philosophy toward managing its loan portfolios is predicated upon careful monitoring, which stresses early detection and response to delinquent and default situations. Delinquent loans are managed by a team of collection specialists and the Company seeks to make arrangements to resolve any delinquent or default situation over the shortest possible time frame.  As a general rule, loans 90 days or more past due with respect to principal or interest are classified as nonaccrual loans. The Company also may use discretion regarding other loans 90 days or more delinquent if the loan is well secured and/or in process of collection.

The following table shows information regarding nonaccrual loans as of the dates indicated:

The Company considers a loan to have defaulted when it reaches 90 days past due. At March 31, 2024 there was one $136,000 commercial real estate loan that defaulted during the three months then ended which was modified with a term extension to a borrower experiencing financial difficulty in the prior 12 months.

At March 31, 2024, the Company had $640,000 in additional commitments to lend to one borrower experiencing financial difficulty, pertaining to a construction loan that was modified during the three months then ended with a term extension.

    Loan modifications to borrowers experiencing financial difficulty are evaluated on a collective basis with loans sharing similar risk characteristics in accordance with the current expected credit loss ("CECL") methodology.
