Unamortized premiums, net of unearned discounts and deferred fees	(15,202)		(13,003)
Loans after the allowance for loan losses, unamortized premiums, unearned discounts and deferred fees	$	13,798,721	$	13,420,317

(1)The balance of accrued interest receivable excluded from amortized cost and the calculation of the allowance for loan losses amounted to $49.1 million and $45.2 million as of June 30, 2023 and December 31, 2022, respectively, and is included within other assets on the Consolidated Balance Sheets.

(2)Automobile loans are included in the other consumer portfolio and amounted to $10.1 million and $18.1 million at June 30, 2023 and December 31, 2022, respectively.

There are no other loan categories that exceed 10% of total loans not already reflected in the preceding table.

The Company’s lending activities are conducted principally in the New England area with the exception of its Shared National Credit Program (“SNC Program”) portfolio. The Company participates in the SNC Program in an effort to improve its industry and geographical diversification. The SNC Program portfolio is included in the Company’s commercial and industrial portfolio. The SNC Program portfolio is defined as loan syndications with exposure over $100 million and with three or more lenders participating.

Most loans originated by the Company are either collateralized by real estate or other assets or guaranteed by federal and local governmental authorities. The ability and willingness of the single-family residential and consumer borrowers to honor their repayment commitments is generally dependent on the level of overall economic activity within the borrowers’ geographic areas and real estate values. The ability and willingness of commercial real estate, commercial and industrial, and construction loan borrowers to honor their repayment commitments is generally dependent on the health of the real estate economy in the borrowers’ geographic areas and the general economy.

Loans Pledged as Collateral

The carrying value of loans pledged to secure advances from the Federal Home Loan Bank (“FHLB”) of Boston (“FHLBB”) were $4.2 billion and $3.9 billion at June 30, 2023 and December 31, 2022, respectively. The balance of funds borrowed from the FHLBB were $314.0 million and $704.1 million at June 30, 2023 and December 31, 2022, respectively.

The carrying value of loans pledged to secure advances from the Federal Reserve Bank (“FRB”) were $1.1 billion at both June 30, 2023 and December 31, 2022, respectively. There were no funds borrowed from the FRB outstanding at June 30, 2023 or December 31, 2022.

Serviced Loans

At June 30, 2023 and December 31, 2022, mortgage loans partially or wholly-owned by others and serviced by the Company amounted to approximately $80.4 million and $84.0 million, respectively.

Purchased Loans

The Company began purchasing residential real estate mortgage loans during the third quarter of 2022. Loans purchased were subject to the same underwriting criteria as those loans originated directly by the Company. During the six months ended June 30, 2023, the Company purchased $32.0 million of residential real estate mortgage loans. The Company

ceased purchases of residential real estate mortgage loans in the first quarter of 2023. Accordingly, no residential real estate mortgage loans were purchased during the three months ended June 30, 2023. No residential real estate mortgage loans were purchased during the six months ended June 30, 2022. As of June 30, 2023 and December 31, 2022, the amortized cost balance of loans purchased was $396.4 million and $376.1 million, respectively.

Allowance for Loan Losses

The allowance for loan losses is established to provide for management’s estimate of expected lifetime credit losses on loans measured at amortized cost at the balance sheet date through a provision for loan losses charged to net income. Charge-offs, net of recoveries, are charged directly to the allowance for loan losses. Commercial and residential loans are charged-off in the period in which they are deemed uncollectible. Delinquent loans in these product types are subject to ongoing review and analysis to determine if a charge-off in the current period is appropriate. For consumer loans, policies and procedures exist that require charge-off consideration upon a certain triggering event depending on the product type.

The following tables summarize the changes in the allowance for loan losses by loan category for the periods indicated:

(1)Represents the adjustment needed to reflect the cumulative day one impact pursuant to the Company’s adoption of ASU 2022-02 (i.e., cumulative effect adjustment related to the adoption of ASU 2022-02 as of January 1, 2023). The adjustment represents a $1.1 million decrease to the allowance attributable to the change in accounting methodology for estimating the allowance for loan losses resulting from the Company’s adoption of the standard.

(2)Represents the adjustment needed to reflect the cumulative day one impact pursuant to the Company’s adoption of ASU 2016-13 (i.e., cumulative effect adjustment related to the adoption of ASU 2016-13 as of January 1, 2022). The adjustment represents a $27.1 million increase to the allowance attributable to the change in accounting methodology for estimating the allowance for loan losses resulting from the Company’s adoption of the standard. The adjustment also includes the adjustment needed to reflect the day one reclassification of the Company’s PCI loan balances to PCD and the associated gross-up of $0.1 million, pursuant to the Company’s adoption of ASU 2016-13.

Reserve for Unfunded Commitments

Management evaluates the need for a reserve on unfunded lending commitments in a manner consistent with loans held for investment. The Company’s adoption of ASU 2022-02 on January 1, 2023 did not impact the reserve for unfunded lending commitments. Upon adoption of ASU 2016-13 on January 1, 2022, the Company recorded a transition adjustment related to the reserve for unfunded lending commitments of $1.0 million, resulting in a total reserve for unfunded lending commitments of $11.1 million as of January 1, 2022. As of June 30, 2023 and December 31, 2022, the Company’s reserve for unfunded lending commitments was $16.0 million and $13.2 million, respectively, which is recorded within other liabilities in the Company's Consolidated Balance Sheets.

Portfolio Segmentation

Management uses a methodology to systematically estimate the amount of expected losses in each segment of loans in the Company’s portfolio. Commercial and industrial business banking, investment commercial real estate, and commercial and industrial loans are evaluated based upon loan-level risk characteristics, historical losses and other factors which form the basis for estimating expected losses. Other portfolios, including owner occupied commercial real estate (which includes business banking owner occupied commercial real estate), commercial construction, residential mortgages, home equity and consumer loans, are analyzed as groups taking into account delinquency ratios, and the Company’s and peer banks’ historical loss experience. For the purposes of estimating the allowance for loan losses, management segregates the loan portfolio into loan categories that share similar risk characteristics such as the purpose of the loan, repayment source, and collateral. These characteristics are considered when determining the appropriate level of the allowance for each category. Some examples of these risk characteristics unique to each loan category include:

Commercial Lending

Commercial and industrial: The primary risk associated with commercial and industrial loans is the ability of borrowers to achieve business results consistent with those projected at origination. Collateral frequently consists of a first lien position on business assets including, but not limited to, accounts receivable, inventory, aircraft and equipment. The primary repayment source is operating cash flow and, secondarily, the liquidation of assets. Under its lending guidelines, the Company generally requires a corporate or personal guarantee from individuals that hold material ownership in the borrowing entity when the loan-to-value of a commercial and industrial loan is in excess of a specified threshold.

Commercial real estate: Collateral values are established by independent third-party appraisals and evaluations. Primary repayment sources include operating income generated by the real estate, permanent debt refinancing, sale of the real

estate and, secondarily, liquidation of the collateral. Under its lending guidelines, the Company generally requires a corporate or personal guarantee from individuals that hold material ownership in the borrowing entity when the loan-to-value of a commercial real estate loan is in excess of a specified threshold.

Commercial construction: These loans are generally considered to present a higher degree of risk than other real estate loans and may be affected by a variety of factors, such as adverse changes in interest rates and the borrower’s ability to control costs and adhere to time schedules. Construction loans are underwritten utilizing feasibility studies, independent appraisal reviews, sensitivity analysis of absorption and lease rates and financial analysis of the developers and property owners. Construction loans are generally based upon estimates of costs and value associated with the completed project. Construction loan repayment is substantially dependent on the ability of the borrower to complete the project and obtain permanent financing.

Business banking: These loans are typically secured by all business assets or commercial real estate. Business banking originations include traditionally underwritten loans as well as partially automated scored loans. Business banking scored loans are determined by utilizing the Company’s proprietary decision matrix that has a number of quantitative factors including, but not limited to, a guarantor’s credit score, industry risk, and time in business. The Company also engages in Small Business Association (“SBA”) lending. The SBA guarantees reduce the Company’s loss due to default and are considered a credit enhancement to the loan structure.

Residential Lending

These loans are made to borrowers who demonstrate the ability to repay principal and interest on a monthly basis. Underwriting considerations include, among others, income sources and their reliability, willingness to repay as evidenced by credit repayment history, financial resources (including cash reserves) and the value of the collateral. The Company maintains policy standards for minimum credit score and cash reserves and maximum loan-to-value consistent with a “prime” portfolio. Collateral consists of mortgage liens on 1-4 family residential dwellings. The policy standards applied to loans originated by the Company are the same as those applied to purchased loans. The Company does not originate or purchase sub-prime or other high-risk loans. Residential loans are originated either for sale to investors or retained in the Company’s loan portfolio. Decisions about whether to sell or retain residential loans are made based on the interest rate characteristics, pricing for loans in the secondary mortgage market, competitive factors and the Company’s capital needs.

Consumer Lending

Consumer home equity: Home equity lines of credit are granted for ten years with monthly interest-only repayment requirements. Full principal repayment is required at the end of the ten-year draw period. Home equity loans are term loans that require the monthly payment of principal and interest such that the loan will be fully amortized at maturity. Underwriting considerations are materially consistent with those utilized in residential real estate. Collateral consists of a senior or subordinate lien on owner-occupied residential property.

Other consumer: The Company’s policy and underwriting in this category, which is comprised primarily of home improvement, automobile and aircraft loans, include the following factors, among others: income sources and reliability, credit histories, term of repayment, and collateral value, as applicable. These are typically granted on an unsecured basis, with the exception of aircraft and automobile loans.

Credit Quality

Commercial Lending Credit Quality

The credit quality of the Company’s commercial loan portfolio is actively monitored and supported by a comprehensive credit approval process and all large dollar transactions are sent for approval to a committee of seasoned business line and credit professionals. The Company maintains an independent credit risk review function that reports directly to the Risk Management Committee of the Board of Directors. Credits that demonstrate significant deterioration in credit quality are transferred to a specialized group of experienced officers for individual attention.

The Company monitors credit quality indicators and utilizes portfolio scorecards to assess the risk of its commercial portfolio. Specifically, the Company utilizes a 15-point credit risk-rating system to manage risk and identify potential problem loans. Under this point system, risk-rating assignments are based upon a number of quantitative and qualitative factors that are under continual review. Factors include cash flow, collateral coverage, liquidity, leverage, position within the industry, internal controls and management, financial reporting, and other considerations. Commercial loan risk ratings are (re)evaluated for each loan at least once-per-year. The risk-rating categories under the credit risk-rating system are defined as follows:

0 Risk Rating - Unrated

Certain segments of the portfolios are not rated. These segments include aircraft loans, business banking scored loan products, and other commercial loans managed by exception. Loans within this unrated loan segment are monitored by delinquency status; and for lines of credit greater than $100,000 in exposure, an annual review is conducted which includes the review of the business score and loan and deposit account performance. The Company supplements performance data with current business credit scores for the business banking portfolio on a quarterly basis. Unrated commercial and business banking loans are generally restricted to commercial exposure of less than $1.5 million. Loans included in this category generally are not required to provide regular financial reporting or regular covenant monitoring.

For purposes of estimating the allowance for loan losses, unrated loans are considered in the same manner as “Pass” rated loans. Unrated loans are included with “Pass” rated loans for disclosure purposes.

1-10 Risk Rating – Pass

Loans with a risk rating of 1-10 are classified as “Pass” and are comprised of loans that range from “substantially risk free” which indicates borrowers of unquestioned credit standing, well-established national companies with a very strong financial condition, and loans fully secured by policy conforming cash levels, through “low pass” which indicates acceptable rated loans that may be experiencing weak cash flow, impending lease rollover or minor liquidity concerns.

11 Risk Rating – Special Mention (Potential Weakness)

Loans to borrowers in this category exhibit potential weaknesses or downward trends deserving management’s close attention. While potentially weak, no loss of principal or interest is envisioned. Included in this category are borrowers who are performing as agreed, are weak when compared to industry standards, may be experiencing an interim loss and may be in declining industries. An element of asset quality, financial flexibility or management is below average. The Company does not consider borrowers within this category as new business prospects. Borrowers rated special mention may find it difficult to obtain alternative financing from traditional bank sources.

12 Risk Rating – Substandard (Well-Defined Weakness)

Loans with a risk-rating of 12 exhibit well-defined weaknesses that, if not corrected, may jeopardize the orderly liquidation of the debt. A loan is classified as substandard if it is inadequately protected by the repayment capacity of the obligor or by the collateral pledged. Specifically, repayment under market rates and terms, or by the requirements under the existing loan documents, is in jeopardy, but no loss of principal or interest is envisioned. There is a possibility that a partial loss of principal and/or interest will occur in the future if the deficiencies are not corrected. Loss potential, while existing in the aggregate portfolio of substandard assets, does not have to exist in individual assets classified as substandard. Non-accrual is possible, but not mandatory, in this class.

13 Risk Rating – Doubtful (Loss Probable)

Loans classified as doubtful have comparable weaknesses as found in the loans classified as substandard, with the added provision that such weaknesses make collection of the debt in full (based on currently existing facts, conditions and values) highly questionable and improbable. Serious problems exist such that a partial loss of principal is likely. The probability of loss exists, but because of reasonably specific pending factors that may work to strengthen the credit, estimated losses are deferred until a more exact status can be determined. Specific reserves will be the amount identified after specific review. Non-accrual is mandatory in this class.

14 Risk Rating – Loss

Loans to borrowers in this category are deemed incapable of repayment. Loans to such borrowers are considered uncollectible and of such little value that continuance as active assets of the Company is not warranted. This classification does not mean that the loans have no recovery or salvage value, but rather, it is not practical or desirable to defer writing off these assets even though partial recovery may occur in the future. Loans in this category have a recorded investment of $0 at the time of the downgrade.

Residential and Consumer Lending Credit Quality

For the Company’s residential and consumer portfolios, the quality of the loan is best indicated by the repayment performance of an individual borrower. Updated appraisals, broker opinions of value and other collateral valuation methods are employed in the residential and consumer portfolios, typically for credits that are deteriorating. Delinquency status is determined using payment performance, while accrual status may be determined using a combination of payment performance,

expected borrower viability and collateral value. Delinquent consumer loans are handled by a team of seasoned collection specialists.

Asset Quality

The Company manages its loan portfolio with careful monitoring. As a general rule, loans more than 90 days past due with respect to principal and interest are classified as non-accrual loans. Exceptions may be made if management believes that collateral held by the Company is clearly sufficient and in full satisfaction of both principal and interest. The Company may also use discretion regarding other loans over 90 days delinquent if the loan is well secured and in the process of collection. Non-accrual loans and loans that are more than 90 days past due but still accruing interest are considered non-performing loans.

Non-accrual loans may be returned to an accrual status when principal and interest payments are no longer delinquent, and the risk characteristics of the loan have improved to the extent that there no longer exists a concern as to the collectability of principal and interest. Loans are considered past due based upon the number of days delinquent according to their contractual terms.

A loan is expected to remain on non-accrual status until it becomes current with respect to principal and interest, the loan is liquidated, or the loan is determined to be uncollectible and is charged-off against the allowance for loan losses.

The following tables show the age analysis of past due loans as of the dates indicated:

(1)The loans on non-accrual status and without an ACL as of both June 30, 2023 and December 31, 2022, were primarily comprised of collateral dependent loans for which the fair value of the underlying loan collateral exceeded the loan carrying value.

The amount of interest income recognized on non-accrual loans during the three and six months ended June 30, 2023 and 2022 was not significant. As of both June 30, 2023 and December 31, 2022, there were no loans greater than 90 days past due and still accruing.

It is the Company’s policy to reverse any accrued interest when a loan is put on non-accrual status and, generally, to record any payments received from a borrower related to a loan on non-accrual status as a reduction of the amortized cost basis of the loan. Accrued interest reversed against interest income for the three and six months ended June 30, 2023 and 2022 was insignificant.

For collateral values for residential mortgage and home equity loans, the Company relies primarily upon third-party valuation information from certified appraisers and values are generally based upon recent appraisals of the underlying collateral, brokers’ opinions based upon recent sales of comparable properties, or estimated auction or liquidation values less estimated costs to sell. As of June 30, 2023 and December 31, 2022, the Company had collateral-dependent residential mortgage and home equity loans totaling $0.4 million and $0.6 million, respectively.

For collateral-dependent commercial loans, the amount of the allowance for loan losses is individually assessed based upon the fair value of the collateral. Various types of collateral are used, including real estate, inventory, equipment, accounts receivable, securities and cash, among others. For commercial real estate loans, the Company relies primarily upon third-party valuation information from certified appraisers and values are generally based upon recent appraisals of the underlying collateral, brokers’ opinions based upon recent sales of comparable properties, estimated equipment auction or liquidation values, income capitalization, or a combination of income capitalization and comparable sales. As of June 30, 2023 and December 31, 2022, the Company had collateral-dependent commercial loans totaling $9.7 million and $16.2 million, respectively.

Appraisals for all loan types are obtained at the time of loan origination as part of the loan approval process and are updated at the time of a loan modification and/or refinance and as considered necessary by management for impairment review purposes. In addition, appraisals are updated as required by regulatory pronouncements.

As of both June 30, 2023 and December 31, 2022, the Company had no residential real estate held in other real estate owned (“OREO”). As of both June 30, 2023 and December 31, 2022, there were no mortgage loans collateralized by residential real estate property for which formal foreclosure proceedings were in-process.

Troubled Debt Restructurings (“TDR”)

As described previously in Note 2, “Summary of Significant Accounting Policies,” the Company adopted ASU 2022-02 on January 1, 2023 which eliminated TDR accounting. Previously, in cases where a borrower experienced financial difficulty and the Company made certain concessionary modifications to contractual terms, the loan was classified as a TDR. The process through which management identified loans as TDR loans, the methodology employed to record any loan losses, and the calculation of any shortfall on collateral dependent loans is described within Note 2, “Summary of Significant Accounting Policies” within the Notes to the Consolidated Financial Statements included within the Company’s 2022 Form 10-K. The below disclosures regarding TDRs relate to prior periods and were included for comparative purposes.

The Company’s policy was to have any TDR loan which was on non-accrual status prior to being modified remain on non-accrual status for approximately six months subsequent to being modified before management considered its return to accrual status. If the TDR loan was on accrual status prior to being modified, it was reviewed to determine if the modified loan should remain on accrual status.

TDR loan information as of December 31, 2022 and the six months ended June 30, 2022 was prepared in accordance with GAAP effective for the Company as of December 31, 2022, or prior to the Company’s adoption of ASU 2022-02.

The following table shows the TDR loans on accrual and non-accrual status as of December 31, 2022:
