NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - BASIS OF PRESENTATION

Independent Bank Corp. (the “Company”) is a state chartered, federally registered bank holding company, incorporated in 1985. The Company is the sole stockholder of Rockland Trust Company (“Rockland Trust” or the “Bank”), a Massachusetts trust company chartered in 1907.

All material intercompany balances and transactions have been eliminated in consolidation. Certain previously reported amounts have been reclassified to conform to the current year’s presentation.

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation of the financial statements, primarily consisting of normal recurring adjustments, have been included. Results for the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023 or any other interim period.

For further information, refer to the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, filed with the Securities and Exchange Commission (the "2022 Form 10-K").

NOTE 2 - RECENT ACCOUNTING STANDARDS UPDATES

    Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 848 "Reference Rate Reform" Update No. 2020-04. Update No. 2020-04 was issued in March 2020 to provide optional expedients and exceptions for applying GAAP to certain contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this update apply only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate ("LIBOR") or another reference rate expected to be discontinued because of reference rate reform. The amendments will not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022 for which an entity has elected certain optional expedients that are retained through the end of the hedging relationship. The amendments in this update are effective for all entities as of March 12, 2020 through December 31, 2022 and do not apply to contract modifications made after December 31, 2022. FASB ASC Topic 848 "Reference Rate Reform" Update No. 2021-01 was subsequently issued in January 2021 and expanded application of the optional expedients to derivative transactions affected by the discounting transition. The Company has not yet adopted the amendments in these updates, but has established a working group to guide the Company’s transition from LIBOR and has begun efforts to transition off the LIBOR index consistent with industry timelines. The working group has identified its products that utilize LIBOR and has implemented fallback language to facilitate the transition to alternative rates. The Company is also evaluating existing platforms and systems as well as alternative indices in its preparation to offer new products tied to the alternative indices. The Company does not anticipate that the adoption of these updates will have a material impact on the Company's financial statements.

Excluded from the table above is accrued interest on available for sale securities of $3.2 million and $3.6 million at March 31, 2023 and December 31, 2022, respectively, which is included within other assets on the consolidated balance sheets. Additionally, the Company did not record any write-offs of accrued interest income on available for sale securities during the three months ended March 31, 2023 and 2022. Furthermore, no securities held by the Company were delinquent on contractual payments nor were any securities placed on non-accrual status at March 31, 2023 and December 31, 2022.

When securities are sold, the adjusted cost of the specific security sold is used to compute the gain or loss on the sale. The Company had no sales of securities available for sale during the three months ended March 31, 2023 and 2022, and therefore no gains or losses were realized during the periods presented.

The following tables show the gross unrealized losses and fair value of the Company’s available for sale securities in an unrealized loss position, and for which the Company has not recorded a provision for credit losses, as of the dates indicated. These available for sale securities are aggregated by major security type and length of time that individual securities have been in a continuous unrealized loss position:

The Company does not intend to sell these investments and has determined, based upon available evidence, that it is more likely than not that the Company will not be required to sell each security before the recovery of its amortized cost basis. In addition, management does not believe that any of the securities are impaired due to reasons of credit quality. As a result, the Company did not recognize a provision for credit losses on these investments during the three months ended March 31, 2023 and 2022. The Company made this determination by reviewing various qualitative and quantitative factors regarding each investment category, such as current market conditions, extent and nature of changes in fair value, issuer rating changes and trends, volatility of earnings, and current analysts’ evaluations.

14

As a result of the Company’s review of these qualitative and quantitative factors, the causes of the impairments listed in the table above by category were as follows at March 31, 2023:

•U.S. Government Agency Securities, U.S. Treasury Securities, Agency Mortgage-Backed Securities, Agency Collateralized Mortgage Obligations and Small Business Administration Pooled Securities: These portfolios have contractual terms that generally do not permit the issuer to settle the securities at a price less than the current par value of the investment. The decline in market value of these securities is attributable to changes in interest rates and not credit quality. Additionally, these securities are implicitly guaranteed by the U.S. Government or one of its agencies.

•Pooled Trust Preferred Securities: This portfolio consists of one below investment grade security which is performing. The unrealized loss on this security is attributable to the illiquid nature of the trust preferred market in the current economic and regulatory environment. Management evaluates collateral credit and instrument structure, including current and expected deferral and default rates and timing. In addition, discount rates are determined by evaluating comparable spreads observed currently in the market for similar instruments.

Held to Maturity Securities

The following table summarizes the amortized cost, fair value and allowance for credit losses of held to maturity securities and the corresponding amounts of gross unrealized gains and losses recognized at the dates indicated:

Substantially all held to maturity securities held by the Company are guaranteed by the U.S. federal government or other government sponsored agencies and have a long history of no credit losses. As a result, management has determined these securities to have a zero loss expectation and therefore the Company did not record a provision for estimated credit losses on any held to maturity securities during the three months ended March 31, 2023 and 2022. Excluded from the table above is accrued interest on held to maturity securities of $4.5 million and $4.4 million as of March 31, 2023 and December 31, 2022, respectively, which is included within other assets on the consolidated balance sheets. Additionally, the Company did not record any write-offs of accrued interest income on held to maturity securities during the three months ended March 31, 2023 and 2022. Furthermore, no securities held by the Company were delinquent on contractual payments nor were any securities placed on non-accrual status at March 31, 2023 and December 31, 2022.

While management has the positive intent and ability to hold the Company's held to maturity securities until maturity, if a decision were made to sell a security within this portfolio, the adjusted cost of the specific security sold would be used to compute the gain or loss on the sale. The Company had no sales of held to maturity securities during the three months ended March 31, 2023 and 2022, and therefore no gains or losses were realized during the periods presented.

The Company monitors the credit quality of held to maturity securities through the use of credit ratings. Credit ratings are monitored by the Company on at least a quarterly basis. As of March 31, 2023, all held to maturity securities held by the Company were rated investment grade or higher.

The actual maturities of certain available for sale or held to maturity securities may differ from the contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. A schedule of the contractual maturities of available for sale and held to maturity securities as of March 31, 2023 is presented below:

(1)Balances of accrued interest receivable excluded from amortized cost and the calculation of allowance for credit losses amounted to $52.7 million and $39.4 million as of March 31, 2023 and March 31, 2022, respectively.

The balance of allowance for credit losses increased to $159.1 million as of March 31, 2023 compared to $152.4 million at December 31, 2022, due primarily to an additional reserve allocation associated with further credit deterioration of a large commercial and industrial credit that migrated to nonperforming status during 2022, resulting in a full specific reserve allocation on the loan.

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 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 and 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.

17

•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 and other specific use properties.  Loans may be written with nonamortizing 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 it is the Company’s policy to obtain 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 owner-occupied 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 restructure 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 of 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.

18

•Potential Weakness: 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.

•Definite Weakness Loss Unlikely: 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.

•Partial Loss Probable: 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.

•Definite 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.

The following table details the amortized cost balances of the Company's loan portfolios, presented by credit quality indicator and origination year as of the dates indicated below:

(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)Loans originated as part of the Paycheck Protection Program ("PPP") established by the Coronavirus Aid, Relief and Economic Security Act (the "CARES Act")t are included within commercial and industrial under the 2021 and 2020 vintage year and "pass" category as these loans are 100% guaranteed by the U.S. Government. Outstanding PPP loans totaled $6.6 million and $99.6 million as of March 31, 2023 and 2022, respectively.

(3)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 2023		December 31 2022
Residential real estate portfolio
FICO score (re-scored)(1)	752		753
LTV (re-valued)(2)	58.7	%	57.0	%
Home equity portfolio
FICO score (re-scored)(1)	771		771
LTV (re-valued)(2)(3)	43.8	%	41.3	%

(1)The average FICO scores at March 31, 2023 are based upon rescores from March 2023, as available for previously originated loans, or origination score data for loans booked in March 2023.  The average FICO scores at December 31, 2022 were based upon rescores available from December 2022, as available for previously originated loans, or origination score data for loans booked in December 2022.

(2)The combined LTV ratios for March 31, 2023 are based upon updated automated valuations as of February 2023, when available, and/or the most current valuation data available.  The combined LTV ratios for December 31, 2022 were based upon updated automated valuations as of November 2022, when available, and/or the most current valuation data available as of such date.  The updated automated valuations provide new information on loans that may be available since the previous valuation was obtained.  If no new information is available, the valuation will default to the previously obtained data or most recent appraisal.

(3)For home equity loans and lines in a subordinate lien, the LTV data represents a combined LTV, taking into account the senior lien data for loans and lines.

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, 2023 and December 31, 2022, the Company's estimated reserve for unfunded commitments amounted to $1.6 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.

It is the Company's policy to reverse any accrued interest when a loan is put on nonaccrual status, and, as such, the Company did not record any interest income on nonaccrual loans during the three months ended March 31, 2023 and 2022, except for instances where nonaccrual loans were paid off in excess of the recorded book balance.

Loan Modifications

In the course of resolving nonperforming loans, the Company may choose to restructure the contractual terms of certain loans. The Company attempts to work out an alternative payment schedule with the borrower in order to avoid foreclosure actions. Terms may be modified to fit the ability of the borrower to repay in line with its current financial status and the restructuring of the loan may include principal forgiveness, interest rate reductions, term extensions, other-than-insignificant payment delays, and/or any combinations thereof. Any loans that are modified are reviewed by the Company to determine whether the modification is the direct result of a borrower experiencing financial difficulty, as the Company adopted the accounting and disclosure requirements for loan modifications made to borrowers experiencing financial difficulty and ceased to recognize TDRs effective January 1, 2023.

Loan modifications made 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. Under previously applicable accounting guidance, the Company determined the amount of allowance for credit losses on TDRs using a discounted cash flow analysis or a fair value of collateral approach if the loan was determined to be individually evaluated. This change in methodology did not have a material impact on the Company's allowance for credit loss estimate.

The following table presents the amortized cost basis at March 31, 2023 of loans modified to borrowers experiencing financial difficulty during the three month period then ended, disaggregated by class of financing receivable and type of modification granted:

	Term Extension
	Amortized Cost Basis		% of Total Class of Financing Receivable
Loan Category	(Dollars in thousands)
Commercial real estate	$	2,540	0.03%

The following table describes the financial effect of the modifications made to borrowers experiencing financial difficulty for the period ending March 31, 2023:

Term Extension
Loan Category	Financial Effect
Commercial real estate	Added a weighted-average contractual term of 2 months to the life of the loan, which reduced monthly payment amounts for the borrowers.
Small business	Added a weighted-average contractual term of 4.3 years to the life of loans, which reduced monthly payment amounts for the borrowers.
Interest Rate Reduction
Loan Category	Financial Effect
Small business	Reduced weighted-average contractual interest rate from 10.00% to 6.50%

The following table shows the Company’s total TDRs and other pertinent information as of the date indicated:

		December 31, 2022
	(Dollars in thousands)
TDRs on accrual status		$	11,278
TDRs on nonaccrual		11,520
Total TDRs		$	22,798

25

There were no new TDRs during the three months ended March 31, 2022.

At March 31, 2023, the Company did not have any additional commitments to lend to borrowers experiencing financial difficulty who were party to a loan modification. At December 31, 2022, the Company had additional commitments to lend to borrowers who had been a party to a TDR of $64,000.

The Company closely monitors the performance of loans modified to borrowers experiencing financial difficulty to understand the effectiveness of its modification efforts. The Company considers a loan to have defaulted when it reaches 90 days past due. During the three months ended March 31, 2023 there were no loans modified to borrowers experiencing financial difficulty that subsequently defaulted, and during the three months ended March 31, 2022, there were no TDRs that were modified during the prior twelve months that subsequently defaulted. Accordingly, all loans modified to borrowers experiencing financial difficulty during the period remained current and were performing in accordance with the modified terms as of March 31, 2023.

NOTE 5 - BORROWINGS

During the three months ended March 31, 2023, the Company entered into advances with the Federal Home Loan Bank ("FHLB") of $879.0 million, due primarily to deposit balance reductions, share repurchase activity, and a proactive strategy to bolster on-balance sheet liquidity during the quarter. These borrowings were comprised of comprised of $379.0 million in overnight FHLB borrowings carrying a rate of 4.95% at March 31, 2023, as well as $500.0 million in one-month term FHLB advances carrying a weighted average interest rate of 5.03% at March 31, 2023. In conjunction with the one-month term FHLB advances, the Company entered into hedges to convert the cost of these borrowings to a total weighted average cost of 4.47% at March 31, 2023.

NOTE 6 - STOCK BASED COMPENSATION

During the three months ended March 31, 2023, the Company had the following activity related to stock based compensation:

Time Vested Restricted Stock Awards

The Company made the following awards of time vested restricted stock:

Date	Shares Granted	Plan	Grant Date Fair Value Per Share		Vesting Period
2/16/2023	77,525	2005 Employee Stock Plan	$	80.65	Ratably over 3 years from grant date
2/16/2023	12,309	2005 Employee Stock Plan	$	80.65	Ratably over 5 years, on each anniversary of February 6, 2023 start date

Performance-Based Restricted Stock Awards

    On February 16, 2023, the Company granted 32,200 performance-based restricted stock awards, representing the maximum number of shares that may be earned under the awards, to certain executive level employees. These performance-based restricted stock awards were issued from the 2005 Employee Stock Plan and were determined to have a grant date fair value per share of $80.65. The number of shares to be vested is contingent upon the Company's attainment of certain performance criteria to be measured at the end of a three year performance period ending December 31, 2025. The awards will vest upon the earlier of the date on which it is determined if the performance goal is achieved subsequent to the performance period or March 31, 2026.

    On March 13, 2023, the performance-based restricted stock awards that were awarded on February 27, 2020 vested at 80% of the maximum target shares awarded, or 12,880 shares, net of forfeitures.

NOTE 7 - DERIVATIVE AND HEDGING ACTIVITIES

The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally to manage the Company’s interest rate risk. Additionally, the Company enters into interest rate derivatives, foreign exchange contracts and risk participation agreements to accommodate the business requirements of its customers (“customer related positions”). The Company minimizes the market and liquidity risks of customer related positions by entering into similar offsetting positions with broker-dealers. Derivative instruments are carried at fair value in the Company's financial statements. The accounting for changes in the fair value of a derivative instrument is dependent upon whether or not it qualifies as a hedge for accounting purposes, and further, by the type of hedging relationship.

The Company does not enter into proprietary trading positions for any derivatives.

The Company is subject to over-the-counter derivative clearing requirements which require certain derivatives to be cleared through central clearing houses. Accordingly, the Company clears certain derivative transactions through the Chicago Mercantile Exchange Clearing House ("CME"). This clearing house requires the Company to post initial and variation margin to mitigate the risk of non-payment, the latter of which is received or paid daily based on the net asset or liability position of the contracts.

Interest Rate Positions

The Company may utilize various interest rate derivatives as hedging instruments against interest rate risk associated with the Company’s borrowings and loan portfolios. An interest rate derivative is an agreement whereby one party agrees to pay a floating rate of interest on a notional principal amount in exchange for receiving a fixed rate of interest on the same notional amount, for a predetermined period of time, from a second party. The amounts relating to the notional principal amount are not actually exchanged.

27

The following tables reflect the Company's derivative positions at the dates indicated below for interest rate swaps which qualify as cash flow hedges for accounting purposes:

March 31, 2023

Total	$	1,450,000						$	(52,244)

The maximum length of time over which the Company is currently hedging its exposure to the variability in future cash flows for forecasted transactions related to the payment of variable interest on existing financial instruments is 6.0 years.

For derivative instruments that are designated and qualify as cash flow hedging instruments, the effective portion of the gains or losses is reported as a component of other comprehensive income and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings.  The Company expects approximately $3.1 million (pre-tax) to be reclassified as an increase to interest income and $25.0 million (pre-tax) to be reclassified as an increase to interest expense, from OCI related to the Company’s cash flow hedges in the twelve months following March 31, 2023.  This reclassification is due to anticipated payments that will be made and/or received on the swaps based upon the forward curve at March 31, 2023.

The Company had no fair value hedges as of March 31, 2023 or December 31, 2022.

Customer Related Positions

Loan level derivatives, primarily interest rate swaps, offered to commercial borrowers through the Company’s loan level derivative program do not qualify as hedges for accounting purposes. The Company believes that its exposure to commercial customer derivatives is limited because these contracts are simultaneously matched at inception with an offsetting dealer transaction. Derivatives with dealer counterparties are then either cleared through a clearinghouse or settled directly with a single counterparty. The commercial customer derivative program allows the Company to retain variable-rate commercial loans while allowing the customer to synthetically fix the loan rate by entering into a variable-to-fixed interest rate swap. The amounts relating to the notional principal amount are not actually exchanged.

28

Foreign exchange contracts offered to commercial borrowers through the Company’s derivative program do not qualify as hedges for accounting purposes. The Company acts as a seller and buyer of foreign exchange contracts to accommodate its customers. To mitigate the market and liquidity risk associated with these derivatives, the Company enters into similar offsetting positions. The amounts relating to the notional principal amount are exchanged.

The Company has entered into risk participation agreements with other dealer banks in commercial loan agreements. Participating banks guarantee the performance on borrower-related interest rate swap contracts. These derivatives are not designated as hedges and, therefore, changes in fair value are recognized in earnings. Under a risk participation-out agreement, a derivative asset, the Company participates out a portion of the credit risk associated with the interest rate swap position executed with the commercial borrower for a fee paid to the participating bank. Under a risk participation-in agreement, a derivative liability, the Company assumes, or participates in, a portion of the credit risk associated with the interest rate swap position with the commercial borrower for a fee received from the other bank.

(1)The Company may enter into one dealer swap agreement which offsets multiple commercial borrower swap agreements.

Mortgage Derivatives

The Company enters into commitments to fund residential mortgage loans at specified rates and times in the future, with the intention that loans may be sold subsequently in the secondary market. Mortgage loan commitments are referred to as derivative loan commitments if the loan that will result from exercise of the commitment will be held for sale upon funding. These commitments are recognized at fair value on the consolidated balance sheet in other assets and other liabilities with changes in their fair values recorded within mortgage banking income. In addition, the Company has elected the fair value option to carry loans held for sale at fair value. The change in fair value of loans held for sale is recorded in current period earnings as a component of mortgage banking income in accordance with the Company's fair value election. The change in fair value associated with loans held for sale was a decrease of $17,000 and $548,000 for the three months ended March 31, 2023 and 2022, respectively. These amounts were offset in earnings by the change in the fair value of mortgage derivatives.

30

Outstanding loan commitments expose the Company to the risk that the price of the loans arising from exercise of the loan commitment might change from inception of the rate lock to funding of the loan due to changes in mortgage interest rates. If interest rates increase, the value of these loan commitments decreases. Conversely, if interest rates decrease, the value of these loan commitments increases. To protect against the price risk inherent in derivative loan commitments, the Company utilizes both "mandatory delivery" and "best efforts" forward loan sale commitments to mitigate the risk of potential decreases in the values of loans that would result from the exercise of the derivative loan commitments. Mandatory delivery contracts are accounted for as derivative instruments. Included in the mandatory delivery forward commitments are To Be Announced securities ("TBAs"). Certain assumptions, including pull through rates and rate lock periods, are used in managing the existing and future hedges. The accuracy of underlying assumptions will impact the ultimate effectiveness of any hedging strategies.

With mandatory delivery contracts, the Company commits to deliver a certain principal amount of mortgage loans to an investor at a specified price on or before a specified date. If the Company fails to deliver the amount of mortgages necessary to fulfill the commitment by the specified date, it is obligated to pay a "pair-off" fee, based on then-current market prices, to the investor/counterparty to compensate the investor for the shortfall. Generally, the Company makes this type of commitment once mortgage loans have been funded and are held for sale, in order to minimize the risk of failure to deliver the requisite volume of loans to the investor and paying pair-off fees as a result. The Company also sells TBA securities to offset potential changes in the fair value of derivative loan commitments. Generally, the Company sells TBA securities by entering into derivative loan commitments for settlement in 30 to 90 days. The Company expects that mandatory delivery contracts, including TBA securities, will experience changes in fair value opposite to the changes in the fair value of derivative loan commitments.

With best effort contracts, the Company commits to deliver an individual mortgage loan of a specified principal amount and quality to an investor if the loan to the underlying borrower closes. Generally, best efforts cash contracts have no pair off risk regardless of market movement. The price the investor will pay the seller for an individual loan is specified prior to the loan being funded (e.g., on the same day the lender commits to lend funds to a potential borrower). The Company expects that these best efforts forward loan sale commitments will experience a net neutral shift in fair value with related derivative loan commitments.

The aggregate amount of net realized gains on sales of such loans included within mortgage banking income was $174,000 and $599,000 for the three months ended March 31, 2023 and 2022, respectively.

Balance Sheet Offsetting

The Company does not offset fair value amounts recognized for derivative instruments. The Company does net the amount recognized for the right to reclaim cash collateral against the obligation to return cash collateral arising from derivative instruments executed with the same counterparty under a master netting arrangement. Collateral legally required to be maintained at dealer banks by the Company is monitored and adjusted as necessary.

A daily settlement occurs through the CME for changes in the fair value of centrally cleared derivatives. Not all of the derivatives are required to be cleared through the daily clearing agent. As a result, the total fair values of loan level derivative assets and liabilities recognized on the Company's financial statements are not equal and offsetting.

    The Company's derivative agreements with institutional counterparties contain various credit-risk related contingent provisions, such as requiring the Company to maintain a well-capitalized capital position. If the Company fails to meet these conditions, the counterparties could request the Company make immediate payment or demand that the Company provide immediate and ongoing full collateralization on derivative positions in net liability positions. All derivative instruments with credit-risk contingent features were in a net asset position at March 31, 2023 and December 31, 2022.

    By using derivatives, the Company is exposed to credit risk to the extent that counterparties to the derivative contracts do not perform as required. Should a counterparty fail to perform under the terms of a derivative contract, the Company's credit exposure on interest rate swaps is limited to the net positive fair value and accrued interest of all swaps with each counterparty. The Company seeks to minimize counterparty credit risk through credit approvals, limits, monitoring procedures, and obtaining collateral, where appropriate. Institutional counterparties must have an investment grade credit rating and be approved by the Company's Board of Directors. In addition, certain derivative contracts executed bilaterally with a dealer counterparty in the over-the-counter market are cleared through a clearinghouse, whereby the clearinghouse becomes the counterparty to the transaction. As such, management believes the risk of incurring credit losses on derivative contracts with those counterparties is remote. The Company's exposure relating to institutional counterparties was $95.3 million and $121.2 million at March 31, 2023 and December 31, 2022, respectively. The Company’s exposure relating to customer counterparties was approximately $5.9 million and $2.2 million at March 31, 2023 and December 31, 2022, respectively. Credit exposure may be reduced by the value of collateral pledged by the counterparty.

NOTE 8 - FAIR VALUE MEASUREMENTS

Fair value is a market-based measure considered from the perspective of a market participant rather than an entity-specific measure. Therefore, even when market assumptions are not readily available, the assumptions applied by the Company when determining fair value reflect those that the Company determines market participants would use to price the asset or liability at the measurement date. If there has been a significant decrease in the volume and level of activity for the asset or liability, regardless of the valuation technique(s) used, the objective of a fair value measurement remains the same. Fair value is the price that would be received if the asset were to be sold or that would be paid if the liability were to be transferred in an orderly market transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. When determining fair value, the Company considers pricing information and other inputs that are current as of the measurement date. In periods of market dislocation, the observability of prices and other inputs may be reduced for certain instruments, or not available at all. The unavailability or reduced availability of pricing or other input information could cause an instrument to be reclassified from one level to another.

The Fair Value Measurements and Disclosures Topic of the FASB ASC defines fair value and establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under the Fair Value Measurements and Disclosures Topic of the FASB ASC are described below:

33

Level 1 – Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level 2 – Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.

Level 3 – Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.

To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

Valuation Techniques

There were no changes in the valuation techniques used during the three months ended March 31, 2023.

Securities

Trading and Equity Securities

These equity securities are valued based on market quoted prices. These securities are categorized in Level 1 as they are actively traded and no valuation adjustments have been applied.

U.S. Government Agency and U.S. Treasury Securities

Fair value is estimated using either multi-dimensional spread tables or benchmarks. The inputs used include benchmark yields, reported trades, and broker/dealer quotes. These securities are classified as Level 2.

Agency Mortgage-Backed Securities

Fair value is estimated using either a matrix or benchmarks. The inputs used include benchmark yields, reported trades, broker/dealer quotes, and issuer spreads. These securities are categorized as Level 2.

Agency Collateralized Mortgage Obligations and Small Business Administration Pooled Securities

The valuation model for these securities is volatility-driven and ratings based, and uses multi-dimensional spread tables. The inputs used include benchmark yields, reported trades, new issue data, broker dealer quotes, and collateral performance. If there is at least one significant model assumption or input that is not observable, these securities are categorized as Level 3 within the fair value hierarchy; otherwise, they are classified as Level 2.

State, County, and Municipal Securities

The fair value is estimated using a valuation matrix with inputs including bond interest rate tables, recent transactions, and yield relationships. These securities are categorized as Level 2.

Single and Pooled Issuer Trust Preferred Securities

The fair value of trust preferred securities, including pooled and single issuer preferred securities, is estimated using external pricing models, discounted cash flow methodologies or similar techniques. The inputs used in these valuations include benchmark yields, reported trades, new issue data, broker dealer quotes, and collateral performance. If there is at least one significant model assumption or input that is not observable, these securities are classified as Level 3 within the fair value hierarchy; otherwise, they are classified as Level 2.

Loans Held for Sale

The Company has elected the fair value option to account for originated closed loans intended for sale. The fair value is measured on an individual loan basis using quoted market prices and when not available, comparable market value or discounted cash flow analysis may be utilized. These assets are typically classified as Level 2.

34

Derivative Instruments

Derivatives

The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The Company incorporates credit valuation adjustments to appropriately reflect nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings. Additionally, in conjunction with fair value measurement guidance, the Company has made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio. Although the Company has determined that the majority of the inputs used to value its interest rate derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its interest rate derivatives and risk participation agreements may also utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties. However, as of March 31, 2023 and December 31, 2022, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are properly classified as Level 2.

Mortgage Derivatives

The fair value of mortgage derivatives is determined based on current market prices for similar assets in the secondary market and, therefore, classified as Level 2 within the fair value hierarchy.

Individually Assessed Collateral Dependent Loans

In accordance with the CECL standard, expected credit losses on individually assessed loans deemed to be collateral dependent are valued based upon the lower of amortized cost or fair value of the underlying collateral less costs to sell.  The inputs used in the appraisals of the collateral are not always observable, and in such cases the loans may be classified as Level 3 within the fair value hierarchy; otherwise, they are classified as Level 2.

Other Real Estate Owned and Other Foreclosed Assets

Other Real Estate Owned ("OREO") and Other Foreclosed Assets, when applicable, are valued at the lower of cost or fair value of the property, less estimated costs to sell. The fair values are generally estimated based upon recent appraisal values of the property less costs to sell the property. Certain inputs used in appraisals are not always observable, and therefore OREO and Other Foreclosed Assets may be classified as Level 3 within the fair value hierarchy.

Goodwill and Other Intangible Assets

Goodwill and other intangible assets are subject to impairment testing. The Company conducts an annual impairment test of goodwill in the third quarter of each year, or more frequently if necessary. Other intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. To estimate the fair value of goodwill and, if necessary, other intangible assets, the Company utilizes both a comparable analysis of relevant price multiples in recent market transactions and a discounted cash flow analysis. Both valuation models require a significant degree of management judgment. In the event the fair value as determined by the valuation model is less than the carrying value, the intangibles may be impaired. If the impairment testing resulted in impairment, the Company would classify the impaired goodwill and other intangible assets subjected to nonrecurring fair value adjustments as Level 3.

(1) The carrying value of individually assessed collateral dependent loans is based on the lower of amortized cost or fair value of the underlying collateral less costs to sell. The fair value of the underlying collateral is generally determined through independent appraisals, which generally include various Level 3 inputs which are not identifiable. Appraisals may be adjusted by management for qualitative factors such as economic factors and estimated liquidation expenses. The range of these possible adjustments may vary.

(a)The fair values presented are based on quoted market prices, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments and/or discounted cash flow analysis.

(b)Fair value of loans is measured using the exit price valuation method, determined primarily by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities or cash flows, while incorporating liquidity and credit assumptions. Additionally, this amount excludes individually assessed collateral dependent loans, which are deemed to be marked to fair value on a nonrecurring basis.

(c)FHLB stock has no quoted market value and is carried at cost; therefore, the carrying amount approximates fair value.

(d)Cash surrender value of life insurance policies is recorded at its cash surrender value (or the amount that can be realized upon surrender of the policy), therefore, carrying amount approximates fair value.

(e)Fair value of demand deposits, savings and interest checking accounts and money market deposits is the amount payable on demand at the reporting date.

(f)Fair value was determined by discounting anticipated future cash payments using rates currently available for instruments with similar remaining maturities.

(g)Fair value was determined based upon market prices of securities with similar terms and maturities.

This summary excludes certain financial assets and liabilities for which the carrying value approximates fair value. For financial assets, these may include cash and due from banks, federal funds sold and short-term investments. For financial liabilities, these may include federal funds purchased. These instruments would all be considered to be classified as Level 1 within the fair value hierarchy. Also excluded from the summary are financial instruments measured at fair value on a recurring and nonrecurring basis, as previously described.

The Company considers its current use of financial instruments to be the highest and best use of the instruments.

NOTE 9 - REVENUE RECOGNITION

A portion of the Company's noninterest income is derived from contracts with customers, and as such, the revenue recognized depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company accounts for such revenues in accordance with ASC 606 - Revenue from Contracts with Customers considers the terms of the contract and all relevant facts and circumstances when applying this guidance. To ensure its alignment with this core principle, the Company measures revenue and the timing of recognition by applying the following five steps:

1.Identify the contract(s) with customers

2.Identify the performance obligations

3.Determine the transaction price

4.Allocate the transaction price to the performance obligations

5.Recognize revenue when (or as) the entity satisfies a performance obligation

The Company has disaggregated its revenue from contracts with customers into categories that depict how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. The following table presents the revenue streams that the Company has disaggregated as of the periods indicated:

	Three Months Ended
	March 31 2023		March 31 2022
	(Dollars in thousands)
Deposit account fees (inclusive of cash management fees)	$	5,916	$	5,493
Interchange fees	2,788		2,472
ATM fees	938		841
Investment management - wealth management and advisory services	8,185		7,904
Investment management - retail investments and insurance revenue	1,594		769
Merchant processing income	470		378
Credit card income	493		372
Other noninterest income	1,198		1,396
Total noninterest income in-scope of ASC 606	21,582		19,625
Total noninterest income out-of-scope of ASC 606	6,660		6,647
Total noninterest income	$	28,242	$	26,272

In each of the revenue streams identified above, there were no significant judgments made in determining or allocating the transaction price, as the consideration and service requirements are generally explicitly identified in the associated contracts. Additional information related to each of the revenue streams is further noted below.

Deposit Account Fees

The Company offers various deposit account products to its customers governed by specific deposit agreements applicable to either personal customers or business customers. These agreements identify the general conditions and obligations of both parties, and include standard information regarding deposit account related fees.

Deposit account services include providing access to deposit accounts as well as access to the various deposit transactional services of the Company. These transactional services are primarily those that are identified in the standard fee schedule, and include, but are not limited to, services such as overdraft protection, wire transfer, and check collection. Revenue is recognized in conjunction with the various services being provided. For example, the Company may assess monthly fixed service fees associated with the customer having access to a deposit account, which can vary depending on the account type and daily account balance. In addition, the Company may also assess separate fixed fees associated with and at the time specific transactions are entered into by the customer. As such, the Company considers its performance obligations to be met concurrently with providing the account access or completing the requested deposit transaction.

40

Cash Management

Cash management services are a subset of the Deposit account fees revenue stream. These services primarily include ACH transaction processing, positive pay and remote deposit services. These services are also governed by separate agreements entered into with the customer. The fee arrangement for these services is structured to assess fees under one of two scenarios, either a per transaction fee arrangement or an earnings credit analysis arrangement. Under the per transaction fee arrangement, fixed fees are assessed concurrently with customers executing the transactions, and as such, the Company considers its performance obligations to be met concurrently with completing the requested transaction. Under the earnings credit analysis arrangement, the Company provides a monthly earnings credit to the customer that is negotiated and determined based on various factors. The credit is then available to absorb the per transaction fees that are assessed on the customer's deposit account activity for the month. Any amount of the transactional fees in excess of the earnings credit is recognized as revenue in that month.

Interchange Fees

The Company earns interchange revenue from its issuance of credit and debit cards granted through its membership in various card payment networks. The Company provides credit cards and debit cards to its customers which are authorized and settled through these payment networks, and in exchange, the Company earns revenue as determined by each payment network's interchange program. The revenue is recognized concurrently with the settlement of card transactions within each network.

ATM Fees

The Company deploys automated teller machines (ATMs) as part of its overall branch network. Certain transactions performed at the ATMs require customers to acknowledge and pay a fee for the requested service. Certain ATM fees are disclosed in the deposit account agreement fee schedules, whereas those assessed to non-Rockland Trust deposit holders are solely determined during the transaction at the machine.

The ATM fee is a fixed dollar per transaction amount, and as such, is recognized concurrently with the overall daily processing and settlement of the ATM activity.

Investment Management - Wealth Management and Advisory Services

The Company offers investment management and trust services to individuals, institutions, small businesses and charitable institutions. Each investment management product is governed by its own contract along with a separate identifiable fee schedule unique to that product. The Company also offers additional services, such as estate settlement, financial planning, tax services and other special services quoted at the client's request.

Asset management and/or custody fees are based upon a percentage of the monthly valuation of the principal assets in the customer's account, whereas fees for additional or special services are fixed in nature and are charged as services are rendered. As the fees are dependent on assets under management, which are susceptible to market factors outside of the Company's control, this variable consideration is constrained and therefore no revenue is estimated at contract initiation. As such, all revenue is recognized in correlation to the monthly management fee determinations or as transactional services are provided. Due to the fact that payments are primarily made subsequent to the valuation period, the Company records a receivable for revenue earned but not received. The following table provides the amount of investment management revenue earned but not received as of the dates indicated:

	March 31, 2023		December 31, 2022
	(Dollars in thousands)
Receivables, included in other assets	$	5,205	$	5,261

Investment Management - Retail Investments and Insurance Revenue

The Company offers the sale of mutual fund shares, unit investment trust shares, third party model portfolios, general securities, fixed and variable annuities and life insurance products through registered representatives who are both employed by the Company and licensed and contracted with various Broker General Agents to offer these products to the Company’s customer base. As such, the Company performs these services as an agent and earns a fixed commission on the sales of these

41

products and services. To a lesser degree, production bonus commissions can also be earned based upon the Company meeting certain volume thresholds.

In general, the Company recognizes commission revenue at the point of sale, and for certain insurance products, may also earn and recognize annual residual commissions commensurate with annual premiums being paid.

Merchant Processing Income

The Company refers customers to third party merchant processing partners in exchange for commission and fee income. The income earned is comprised of multiple components, including a fixed referral fee per each referred customer, a rebate amount determined primarily as a percentage of net revenue earned by the third party from services provided to each referred customer, and overall production bonus commissions if certain new account production thresholds are met. Merchant processing income is recognized in conjunction with either completing the referral to earn the fixed fee amount or as the merchant activity is processed to derive the Company's rebate and/or production bonus amounts.

Credit Card Income

The Company provides consumer and business credit card solutions to its customers by soliciting new accounts on behalf of a third party credit card provider in exchange for a fee. The income earned is comprised of new account incentive payments as well as a percentage of interchange income earned by the third party provider offering the consumer and business purpose revolving credit accounts. The credit card income is recognized in conjunction with the establishment of each new credit card member or as the interchange is earned by the third party in connection with net purchase transactions made by the credit card member.

Other Noninterest Income

The Company earns various types of other noninterest income that fall within the scope of the new revenue recognition rules, and have been aggregated into one general revenue stream in the table noted above. This amount includes, but is not limited to, the following types of revenue with customers:

Safe Deposit Rent

    The Company rents out the use of safe deposit boxes to its customers, which can be accessed when the bank is open for business. The safe deposit box rental fee is paid upfront and is recognized as revenue ratably over the annual term of the contract.

1031 Exchange Fee Revenue

    The Company provides like-kind exchange services pursuant to Section 1031 of the Internal Revenue Code. Fee income is recognized in conjunction with completing the exchange transactions.

Foreign Currency

    The Company earns fee income associated with various transactions related to foreign currency product offerings, including foreign currency bank notes and drafts and foreign currency wires. The majority of this income is derived from commissions earned related to customers executing the above mentioned foreign currency transactions through arrangements with third party correspondents.

NOTE 11 - COMMITMENTS AND CONTINGENCIES

Financial Instruments with Off-Balance Sheet Risk

    In the normal course of business, the Company enters into various transactions to meet the financing needs of its customers, which, in accordance with GAAP, are not included in its consolidated balance sheets. These transactions include commitments to extend credit and standby letters of credit, and loan exposures with recourse, which involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. The Company minimizes its exposure to loss under these commitments by subjecting them to credit approval and monitoring procedures.

    The Company enters into contractual commitments to extend credit, normally with fixed expiration dates or termination clauses, at specified rates and for specific purposes. Substantially all of these commitments to extend credit are contingent upon customers maintaining specific credit standards at the time of loan funding.

The Company has certain loan exposures for which there is recourse. These loan relationships could require the Company to repurchase or cover certain losses per agreements for certain loans that are either sold or referred to third parties.

    Standby letters of credit are written conditional commitments issued to guarantee the performance of a customer to a third party. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Company would be required to fund the commitment. The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount of the commitment. If the commitment were funded, the Company would be entitled to seek recovery from the customer. The Company’s policies generally require that standby letter of credit arrangements contain security and debt covenants similar to those contained in loan agreements.

    The fees collected in connection with the issuance of standby letters of credit are representative of the fair value of the Company's obligation undertaken in issuing the guarantee. In accordance with applicable accounting standards related to guarantees, fees collected in connection with the issuance of standby letters of credit are deferred. The fees are then recognized in income proportionately over the life of the standby letter of credit agreement. The deferred standby letter of credit fees represent the fair value of the Company's potential obligations under the standby letter of credit guarantees.

    The following table summarizes the above financial instruments at the dates indicated:

	March 31, 2023		December 31, 2022
	(Dollars in thousands)
Commitments to extend credit	$	4,594,573	$	4,566,041
Loan exposures sold with recourse	164,438		167,274
Standby letters of credit	22,850		24,941
Deferred standby letter of credit fees	190		168

44

Lease Commitments

The Company leases office and parking space, space for ATM locations, and certain branch locations under noncancellable operating leases. Several of these leases contain renewal options to extend lease terms for a period of 1 to 20 years.

There has been no significant change in the future minimum lease payments payable by the Company since December 31, 2022. See the Company's 2022 Form 10-K for information regarding leases and other commitments.

Other Contingencies

At March 31, 2023, the Bank was involved in pending lawsuits that arose in the ordinary course of business. Management has reviewed these pending lawsuits with legal counsel and has taken into consideration the view of counsel as to their outcome. In the opinion of management, the final disposition of pending lawsuits is not expected to have a material adverse effect on the Company’s financial position or results of operations.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion should be read in conjunction with the consolidated financial statements, notes and tables included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, filed with the Securities and Exchange Commission (the "2022 Form 10-K").

48

Executive Level Overview

    Management evaluates the Company's operating results and financial condition using measures that include net income, earnings per share, return on assets and equity, return on tangible common equity, net interest margin, tangible book value per share, asset quality indicators, and many others. These metrics are used by management to make key decisions regarding the Company's balance sheet, liquidity, interest rate sensitivity, and capital resources and assist with identifying opportunities for improving the Company's financial position or operating results. The Company focuses on organic growth, but will also consider growth through acquisition. Any potential acquisition opportunities are evaluated for the potential to provide a satisfactory financial return as well as other criteria (ease of integration, synergies, geographical location).

First Quarter 2023 Results

Net income for the three months ended March 31, 2023 was $61.2 million, or $1.36 on a diluted earnings per share basis, as compared to $53.1 million, or $1.12 on a diluted earnings per share basis, for the three months ended March 31, 2022, representing increases of 15.3% and 21.4%, respectively. Results for three months ended March 31, 2022 reflect merger and acquisition-related costs of $7.1 million, pre-tax, associated with the Meridian Bancorp, Inc. ("Meridian") acquisition and its subsidiary, East Boston Savings Bank ("EBSB"), which closed in the fourth quarter of 2021. Excluding these merger and acquisition costs, operating net income was $58.2 million, or $1.23 on a diluted per share basis for three months ended March 31, 2022. There were no such costs for the three months ended March 31, 2023. See "Non-GAAP Measures" below for a reconciliation of non-GAAP measures.

First quarter 2023 results reflected the following key drivers:

•Flat overall loan balances, reflecting decreased demand and a cautious posture over new commitments;

•3.8% decrease in deposits;

•Increases in both on and off balance sheet liquidity;

•Number of households increased by 0.5% ;

•Increased provision due to specific reserve allocation; asset quality metrics strong;

•Wealth Management assets under administration increased to $6.1 billion;

•52.7% efficiency ratio;

•Completion of full $120.0 million stock buyback program; and

•Modest tangible book value per share growth

49

Interest-Earning Assets

    The results depicted in the following table reflect the trend of the Company's interest-earning assets over the past five quarters. While the Company employs a longer term strategy that typically emphasizes loan growth commensurate with overall economic growth, changes over the five quarter period reflect a decline in interest-earning cash balances, largely attributable to a competitive rate environment, redeployment of excess customer liquidity, and the completion of two stock repurchase programs over the course of 2022 and through the first quarter of 2023. The following table summarizes the Company's interest-earning assets as of the periods indicated:

    Management strives to be disciplined about loan pricing and considers interest rate sensitivity when generating loan assets. In addition, management takes a disciplined approach to credit underwriting, seeking to avoid undue credit risk and credit losses.

50

Funding and Net Interest Margin

    The Company's overall sources of funding reflect strong business and retail deposit growth with a management strategy of relying upon core deposit growth to substantially fund loans. Total borrowings increased by $879.0 million during the first quarter of 2023, in response to deposit balance reductions and share repurchase activity, along with preemptive measures to bolster on-balance sheet liquidity in response to the high deposit risk environment experienced across the banking industry during the month of March 2023. The following chart shows sources of funding and percentage of core deposits to total deposits for the trailing five quarters:

    The following table shows the net interest margin and cost of deposits trends for the trailing five quarters:

51

Noninterest Income

    Noninterest income is primarily comprised of deposit account fees, interchange and ATM fees, investment management fees and mortgage banking income. The following chart shows trends in the components of noninterest income over the past five quarters:

52

Expense Control

    Management seeks to take a balanced approach to noninterest expense control by monitoring ongoing operating expenses while making needed capital expenditures and prudently investing in growth initiatives. The Company’s primary expenses arise from Rockland Trust’s employee salaries and benefits, as well as expenses associated with buildings and equipment.

The following chart depicts the Company's efficiency ratio on a GAAP basis (calculated by dividing noninterest expense by the sum of noninterest income and net interest income), as well as the Company's efficiency ratio on a non-GAAP operating basis, if applicable (calculated by dividing noninterest expense, excluding certain noncore items, by the sum of noninterest income, excluding certain noncore items, and net interest income), over the past five quarters:

*See "Non-GAAP Measures" below for a reconciliation to GAAP financial measures.

53

Capital

    The Company's approach with respect to revenue and expense is designed to promote long-term earnings growth, which in turn contributes to capital growth. Capital is primarily impacted by earnings retention, dividends and opportunistic share repurchases. The following chart shows the Company's book value and tangible book value per share over the past five quarters:

*See "Non-GAAP Measures" below for a reconciliation to GAAP financial measures.

    The Company declared a quarterly cash dividend of $0.55 per share for the first quarter of 2023, representing an increase of 7.8% from the 2022 first quarter dividend rate of $0.51. Additionally, during the first quarter of 2023 the Company repurchased 1.6 million shares of its common stock for $120.0 million at an average price of $74.18, marking the full completion of its stock repurchase program announced in October 2022.

Non-GAAP Measures

    When management assesses the Company’s financial performance for purposes of making day-to-day and strategic decisions, it does so based upon the performance of its core banking business, which is primarily derived from the combination of net interest income and noninterest or fee income, reduced by operating expenses, the provision for credit losses, and the impact of income taxes and other noncore items shown in the table that follows. There are items that impact the Company's results that management believes are unrelated to its core banking business such as gains or losses on the sales of securities, merger and acquisition expenses, provision for credit losses on acquired portfolios, loss on extinguishment of debt, impairment, and other items, such as one-time adjustments as a result of changes in laws and regulations. Management, therefore, excludes items management considers to be noncore when computing the Company’s non-GAAP operating earnings and operating EPS, noninterest income on an operating basis and efficiency ratio on an operating basis. Management believes excluding these items facilitates greater visibility into the Company’s core banking business and underlying trends that may, to some extent, be obscured by inclusion of such items.

Management also supplements its evaluation of financial performance with an analysis of tangible book value per share (which is computed by dividing stockholders' equity less goodwill and identifiable intangible assets, or tangible common equity, by common shares outstanding) and with the Company's tangible common equity ratio (which is computed by dividing tangible common equity by tangible assets) which are non-GAAP measures. The Company has included information on these tangible ratios because management believes that investors may find it useful to have access to the same analytical tools used by management to assess performance and identify trends.  The Company has recognized goodwill and other intangible assets in conjunction with merger and acquisition activities.  Excluding the impact of goodwill and other intangibles in measuring asset and capital values for the ratios provided, along with other bank standard capital ratios, facilitates comparison of the capital adequacy of the Company to other companies in the financial services industry.

These non-GAAP measures should not be viewed as a substitute for financial results determined in accordance with GAAP. An item which management deems to be noncore and excludes when computing these non-GAAP measures can be of

54

substantial importance to the Company’s results for any particular period. The Company’s non-GAAP performance measures are not necessarily comparable to similarly named non-GAAP performance measures which may be presented by other companies.

Critical Accounting Estimates

Critical accounting policies are defined as those that are reflective of significant management judgments and uncertainties, and could potentially result in materially different results under different assumptions and conditions. Certain estimates associated with these policies inherently have a greater reliance on the use of assumptions and judgments and, as such, have a greater possibility of producing results that could be materially different than originally reported. These critical accounting estimates are defined as estimates made in accordance with GAAP that involve a significant level of estimation uncertainty and have had, or are reasonably likely to have, a material impact on financial condition or results of operations.

There have been no material changes in critical accounting estimates during the first three months of 2023. Refer to "Critical Accounting Estimates" in Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations" in the Company's 2022 Form 10-K for a complete listing of critical accounting policies.

FINANCIAL POSITION

Securities Portfolio The Company’s securities portfolio consists of trading securities, equity securities, securities available for sale, and securities which management intends to hold until maturity. Securities decreased by $19.3 million, or 0.6%, at March 31, 2023 as compared to December 31, 2022, driven primarily by paydowns, calls, and maturities, partially offset by unrealized gains of $22.2 million in the available for sale portfolio. As a result, the Company's ratio of securities to total assets decreased to 16.0% at March 31, 2023 compared to 16.2% at December 31, 2022. The Company estimates expected credit losses for its available for sale and held to maturity securities in accordance with the current expected credit loss ("CECL") methodology. Further details regarding the Company's measurement of expected credit losses on securities can be found in Note 3 “Securities” within the Notes to Consolidated Financial Statements included in Part I. Item 1 of this Report.

56

    Residential Mortgage Loan Sales The Company’s primary loan sale activity arises from the sale of government sponsored enterprise eligible residential mortgage loans. The Company originates residential loans with the intention of either selling them in the secondary market or holding them in the Company's residential real estate portfolio. When a loan is sold, the Company enters into agreements that contain representations and warranties about the characteristics of the loans sold and their origination. The Company may be required to either repurchase mortgage loans or to indemnify the purchaser from losses if representations and warranties are found to be not accurate in all material respects. The Company incurred no material losses related to residential mortgage repurchases during the three months ended March 31, 2023 and 2022, respectively.

    The following table shows the total residential real estate loans closed and the breakdown of amounts held in portfolio or sold (or held for sale) in the secondary market during the periods indicated:

Table 1 - Closed Residential Real Estate Loans

	Three Months Ended March 31

Sold or held for sale in the secondary market	9,934		37,245
Total closed loans	$	101,460	$	217,770

The Company experienced a lower volume of residential real estate loans sales for the three months ended March 31, 2023 compared to the same prior year periods, driven primarily by reduced customer demand in the rising interest rate environment.

    The table below reflects additional information related to the loans sold during the periods indicated:

Total loans sold	$	11,589	$	54,284

(1)All loans sold with servicing rights retained during the three months ended March 31, 2022 were sold without recourse.

    When a loan is sold, the Company may decide to also sell the servicing of sold loans for a servicing release premium, simultaneously with the sale of the loan, or the Company may opt to sell the loan and retain the servicing. In the event of a sale with servicing rights retained, a mortgage servicing asset is established, which represents the then current estimated fair value based on market prices for comparable mortgage servicing contracts, when available, or alternatively is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. Servicing rights are recorded in other assets in the Consolidated Balance Sheets, are amortized in proportion to and over the period of estimated net servicing income, and are assessed for impairment based on fair value at each reporting date. Impairment is determined by stratifying the rights based on predominant characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance, to the extent that fair value is less than the capitalized amount. If the Company later determines that all or a portion of the impairment no longer exists, a reduction of the allowance may be recorded as an increase to income. The principal balance of loans serviced by the Bank on behalf of investors was $320.9 million, $327.5 million and $361.7 million at March 31, 2023, December 31, 2022, and March 31, 2022, respectively.

Loan Portfolio Total loans at March 31, 2023 increased by $19.3 million, or 0.1%, (0.6% on an annualized basis) when compared to December 31, 2022. The commercial portfolio decreased by $26.7 million, or 0.2% during the quarter, reflecting decreased demand and an overall cautious posture over new commitments. Small business loans rose modestly in the first quarter. As in prior quarters, the vast majority of residential real estate originations were retained on the balance sheet, resulting in growth of $60.1 million, or 3.0% for the quarter while home equity balances remained relatively flat.

The Company’s commercial real estate loan portfolio, inclusive of commercial construction, is the Company’s largest loan type concentration. The Company believes that this portfolio is also well-diversified with loans secured by a variety of property types, such as owner-occupied and nonowner-occupied commercial, retail, office, industrial, warehouse, and other special purpose properties, such as hotels, motels, nursing homes, restaurants, churches, recreational facilities, marinas, and golf courses. Commercial real estate also includes loans secured by certain residential-related property types, including multi-family apartment buildings, residential development tracts and condominiums. The following pie chart shows the diversification of the commercial real estate loan portfolio as of March 31, 2023:

(1)Included in the total commercial real estate balance are $1.0 billion, or 11.8%, of owner occupied commercial real estate loans.

    The Company's consumer portfolio primarily consists of both fixed-rate and adjustable-rate residential real estate loans as well as residential construction lending related to single-home residential development within the Company's market area. The Company also provides home equity loans and lines of credit that may be made as a fixed-rate term loan or under a variable rate revolving line of credit secured by a first or junior mortgage on the borrower's residence or second home. Additionally, the Company makes loans for other personal needs. Other consumer loans primarily consist of installment loans and overdraft protections. The residential real estate, home equity and other consumer portfolios totaled $3.2 billion at March 31, 2023, as noted below:

	(Dollars in thousands)
Average loan size	$	100
Largest individual consumer loan outstanding	$	5,132

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

Delinquency     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.  The Company seeks to make arrangements to resolve any delinquent or default situation over the shortest possible time frame.  Generally, the Company requires that a delinquency notice be mailed to a borrower upon expiration of a grace period (typically no longer than 15 days beyond the due date).  Reminder notices may be sent and telephone calls may be made prior to the expiration of the grace period. If the delinquent status is not resolved within a reasonable time frame following the mailing of a delinquency notice, the Bank’s personnel charged with managing its loan portfolios contacts the borrower to ascertain the reasons for delinquency and the prospects for payment.  Any subsequent actions taken to resolve the delinquency will depend upon the nature of the loan and the length of time that the loan has been delinquent. The borrower’s needs are considered as much as reasonably possible without jeopardizing the Bank’s position. A late charge is usually assessed on loans upon expiration of the grace period.

Nonaccrual Loans     As a general rule, loans 90 days or more past due with respect to principal or interest are classified as nonaccrual loans. However, certain loans that are 90 days or more past due may be kept on an accruing status if the loans are well secured and in the process of collection. Income accruals are suspended on all nonaccrual loans and all previously accrued

and uncollected interest is reversed against current income. A loan remains on nonaccrual status until it becomes current with respect to principal and interest (and in certain instances remains current for up to six months), the loan is liquidated, or when the loan is determined to be uncollectible and is charged-off against the allowance for credit losses.

Loan Modifications In the course of resolving problem loans, the Company may choose to restructure the contractual terms of certain loans. The Company attempts to work out an alternative payment schedule with the borrower in order to avoid or cure a default. Terms may be modified to fit the ability of the borrower to repay in line with its current financial status and the restructuring of the loan may include adjustments to term extensions, interest rates, other than insignificant payment delays and/or a combination thereof. These actions are intended to minimize economic loss and avoid foreclosure or repossession of collateral. If such efforts by the Bank do not result in satisfactory performance, the loan is referred to legal counsel, at which time foreclosure proceedings are initiated. At any time prior to a sale of the property at foreclosure, the Bank may terminate foreclosure proceedings if the borrower is able to work out a satisfactory payment plan. All loan restructurings are reviewed by the Company to identify if a borrower is deemed to be experiencing financial difficulty at time of the restructuring.

It is the Company’s policy to have any restructured loans which are on nonaccrual status prior to being modified remain on nonaccrual status for six months, subsequent to being modified, before management considers their return to accrual status. If the restructured loan is on accrual status prior to being modified, it is reviewed to determine if the modified loan should remain on accrual status.

    Purchased Credit Deteriorated Loans    Purchased Credit Deteriorated ("PCD") loans are acquired loans which have shown a more-than-insignificant deterioration in credit quality since origination. PCD loans are recorded at amortized cost with an allowance for credit losses recorded upon purchase.

Nonperforming Assets     Nonperforming assets are typically comprised of nonperforming loans and other real estate owned. Nonperforming loans consist of nonaccrual loans and loans that are 90 days or more past due but still accruing interest.

Allowance for Credit Losses  The allowance for credit losses is maintained at a level that management considers appropriate to provide for the Company's current estimate of expected lifetime credit losses on loans measured at amortized cost. The allowance is increased by providing for credit losses through a charge to expense and by credits for recoveries of loans previously charged-off and is reduced by loans being charged-off.

In accordance with the CECL methodology, the Company estimates credit losses for financial assets on a collective basis for loans sharing similar risk characteristics using a quantitative model combined with an assessment of certain qualitative factors designed to address forecast risk and model risk inherent in the quantitative model output. The model estimates

63

expected credit losses using loan level data over the contractual life of the exposure, considering the effect of prepayments. Economic forecasts are incorporated into the estimate over a reasonable and supportable forecast period of one year, beyond which is a reversion to the Company's historical long-run average for a period of six months. The Company's qualitative assessment is structured based upon nine environmental factors impacting the expected risk of loss within the loan portfolio. Loans that do not share similar risk characteristics with any pools of assets are subject to individual assessment and are removed from the collectively assessed pools to avoid double counting. For the loans that will be individually assessed, the Company uses either a discounted cash flow (“DCF”) approach or a fair value of collateral approach. The latter approach is used for loans deemed to be collateral dependent or when foreclosure is probable.

The balance of allowance for credit losses increased to $159.1 million as of March 31, 2023 compared to $152.4 million at December 31, 2022, due primarily to an additional reserve allocation associated with further credit deterioration of a large commercial and industrial credit that migrated to nonperforming status during 2022, resulting in a full specific reserve allocation on the loan.

Management's forecast anticipates that the federal funds rates will continue to rise in the near term and that the recent U.S. bank failures are not symptomatic of a serious broader problem in the financial system. The forecast used by management also anticipates that a full-employment economy is expected to continue, that lawmakers will suspend or increase limits on the U.S. debt ceiling prior to the default date, and that prices for office properties and houses are expected to decline over the course of 2023. Additionally, the allowance for credit losses is qualitatively adjusted on a quarterly basis in order to ensure coverage for relationships that are deemed to be more at risk within certain industries, specific collateral types, or other specific characteristics that may be highly impacted by the current economic environment.

For purposes of the allowance for credit losses, management segregates the loan portfolio into the portfolio segments detailed in the table below. The allocation of the allowance for credit losses is made to each loan category using the analytical techniques and estimation methods described in this Report. While these amounts represent management’s best estimate of credit losses at the evaluation dates, they are not necessarily indicative of either the categories in which actual losses may occur or the extent of such actual losses that may be recognized within each category. Each of these loan categories possess unique risk characteristics that are considered when determining the appropriate level of allowance for each segment. The total allowance is available to absorb losses from any segment of the loan portfolio.

The following table sets forth the allocation of the allowance for credit losses by loan category at the dates indicated:

Table 7 - Summary of Allocation of Allowance for Credit Losses

	March 31 2023				December 31 2022

Total allowance for credit losses	$	159,131	100.0	%	$	152,419	100.0	%

(1)Total loans in this category are inclusive of $6.6 million and $9.1 million in loans at March 31, 2023 and December 31, 2022, respectively, which were originated as part of the Paycheck Protection Program ("PPP") established by the Coronavirus Aid, Relief and Economic Security Act (the "CARES Act"). These loans have been excluded from the credit loss calculations as these loans are 100% guaranteed by the U.S. Government.

To determine if a loan should be charged-off, all possible sources of repayment are analyzed. Possible sources of repayment include the potential for future cash flows, the value of the Bank’s collateral, and the strength of co-makers or guarantors. When available information confirms that specific loans or portions thereof are uncollectible, these amounts are promptly charged-off against the allowance for credit losses and any recoveries of such previously charged-off amounts are credited to the allowance.

Regardless of whether a loan is unsecured or collateralized, the Company charges off the amount of any confirmed loan loss in the period when the loans, or portions of loans, are deemed uncollectible. For troubled, collateral-dependent loans, loss-confirming events may include an appraisal or other valuation that reflects a shortfall between the value of the collateral and the carrying value of the loan or receivable, or a deficiency balance following the sale of the collateral.

For additional information regarding the Company’s allowance for credit losses, see Note 4 "Loans, Allowance for Credit Losses and Credit Quality" within the Notes to Consolidated Financial Statements included in Part I. Item 1 of this Report.

Federal Home Loan Bank Stock The FHLB is a cooperative that provides services to its member banking institutions. The primary reason for the FHLB of Boston membership is to gain access to a reliable source of wholesale funding as a tool to manage liquidity and interest rate risk. The purchase of stock in the FHLB is a requirement for a member to gain access to funding. The Company either purchases additional FHLB stock or is subject to redemption of FHLB stock proportional to the volume of funding received. The Company views the holdings as a necessary long-term investment for the purpose of balance sheet liquidity and not for investment return. The Company's investments in FHLB of Boston stock increased to $40.3 million at March 31, 2023 compared to $5.2 million at December 31, 2022, driven by an increase in FHLB borrowings during the quarter of $879.0 million.

    Goodwill and Other Intangible Assets Goodwill and other intangible assets were $1.0 billion at both March 31, 2023 and December 31, 2022.

66

The Company typically performs its annual goodwill impairment testing during the third quarter of the year, unless certain indicators suggest earlier testing to be warranted. In light of the turmoil experienced in the U.S. banking industry during the first quarter of 2023, and the related industry wide impact on bank stock valuations, the Company performed an interim goodwill impairment testing during the quarter and determined that the Company's goodwill was not impaired as of March 31, 2023. Other intangible assets are also reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. There were no other events or changes during the first quarter of 2023 that indicated impairment of goodwill and other intangible assets.

Cash Surrender Value of Life Insurance Policies The Bank holds life insurance policies for the purpose of offsetting its future obligations to its employees under its retirement and benefits plans. The cash surrender value of life insurance policies was $295.3 million at March 31, 2023 compared to $293.3 million at December 31, 2022, representing an increase of $1.9 million, or 0.7%, primarily due to income earned on the policies.

The Company recorded tax exempt income from life insurance policies of $1.9 million and $1.8 million for the three months ended March 31, 2023 and 2022, respectively.

Deposits As of March 31, 2023, total deposits were $15.3 billion, representing a $606.8 million, or 3.8%, decrease from December 31, 2022, primarily reflective of industry wide dislocations in the first quarter along with seasonality, a competitive rate environment, and redeployment of customer excess liquidity due to inflationary and other factors. The total cost of deposits increased 54 basis points to 0.59% for the three months ended March 31, 2023 as compared to 0.05% for the same prior year period. The increase in the cost of deposits was driven by the higher rate environment driven by the Federal Reserve's rate hikes over the past year.

The Company's deposits are comprised primarily of core deposits (demand, savings, and money market), as well as time deposits. Core deposits represented 85.6% and 87.9% of total deposits as of March 31, 2023 and December 31, 2022, respectively, with the first quarter 2023 decrease driven primarily by core deposit outflows in conjunction with growth in higher yielding time deposits. In addition, the Company may also utilize brokered deposit sources, as needed, with balances of $95.4 million and $102.6 million outstanding at March 31, 2023 and December 31, 2022, respectively.

The Company's deposits accounts are insured to the maximum extent permitted by law the Deposit Insurance Fund which is administered by the Federal Deposit Insurance Corporation ("FDIC"). The FDIC offers insurance coverage on deposits up to the federally insured limit of $250,000. The Company participates in the IntraFi Network, allowing it to provide easy access to multi-million dollar FDIC deposit insurance protection on certificate of deposit and money market investments for consumers, businesses and public entities. This channel, which is not included in the Company's core deposits, allows the Company to seek additional funding in potentially large quantities by attracting deposits from outside the Bank’s core market, and amounted to $698.3 million and $653.6 million at March 31, 2023 and December 31, 2022, respectively. The estimated balance of uninsured deposits at the Bank are $4.7 billion and $5.3 billion as of March 31, 2023 and December 31, 2022, respectively. Included in these amounts are $659.0 million and $605.0 million of collateralized deposits, which offer additional protection.

Borrowings  The Company's borrowings consist of both short-term and long-term borrowings and provide the Bank with one of its primary sources of funding. Maintaining available borrowing capacity provides the Bank with a contingent source of liquidity. Borrowings were $992.4 million at March 31, 2023, representing an increase of $879.0 million as compared to December 31, 2022, driven primarily by deposit balance reductions and share repurchase activity during the quarter, as well as preemptive measures to bolster on-balance sheet liquidity. The additional borrowings were comprised primarily of short term borrowings from the FHLB. In conjunction with these borrowings, the Company entered into $300.0 million of hedges resulting in a weighted average cost of 3.7% over an average term of 3.5 years.

Additionally, the Bank had $7.3 billion and $4.4 billion of assets pledged as collateral against borrowings at March 31, 2023 and December 31, 2022, respectively. These assets are primarily pledged to the FHLB of Boston and the Federal Reserve Bank of Boston and pledged amounts were proactively increased by management during the first quarter of 2023 as part of the Company's strategy to bolster off-balance sheet liquidity in response to recent industry events.

Capital Resources On March 16, 2023 the Company’s Board of Directors declared a cash dividend of $0.55 per share to shareholders of record as of the close of business on March 27, 2023. This dividend was paid on April 6, 2023.

The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of the Company’s and the Bank’s assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.

Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the table below) of Total, Tier 1 Capital and Common Equity Tier 1 Capital (as defined for regulatory purposes) to risk weighted assets (as defined for regulatory purposes) and Tier 1 Capital to average assets (as defined for regulatory purposes). At March 31, 2023 and December 31, 2022, the Company and the Bank exceeded the minimum requirements for all applicable ratios that were in effect during the respective periods. The Company’s and the Bank’s capital amounts and ratios are presented in the following table, along with the applicable minimum requirements as of each date indicated:

    In addition to the minimum risk-based capital requirements outlined in the table above, the Company is required to maintain a minimum capital conservation buffer, in the form of common equity, in order to avoid restrictions on capital distributions and discretionary bonuses. The required amount of the capital conservation buffer is 2.5%. At March 31, 2023, the Company's capital levels exceeded the buffer.

Dividend Restrictions The Company is subject to capital and dividend requirements administered by federal and state bank regulators, and the Company will not declare a cash dividend that would cause the Company to violate regulatory requirements. The Company is, in the ordinary course of business, dependent upon the receipt of cash dividends from the Bank to pay cash dividends to shareholders and satisfy the Company’s other cash needs. Federal and state law impose limits on capital distributions by the Bank. Massachusetts-chartered banks, such as the Bank, may declare from net profits cash dividends not more frequently than quarterly and non-cash dividends at any time. No dividends may be declared, credited, or paid if the Bank’s capital stock would be impaired. Massachusetts Bank Commissioner approval is required if the total of all dividends declared by the Bank in any calendar year would exceed the total of its net profits for that year combined with its retained net profits of the preceding two years, less any required transfer to surplus or a fund for the retirement of any preferred stock. Dividends paid by the Bank to the Company totaled $66.4 million and $25.0 million for the three months ended March 31, 2023 and 2022, respectively.

Trust Preferred Securities In accordance with the applicable accounting standard related to variable interest entities, the common stock of trusts which have issued trust preferred securities has not been included in the consolidated financial statements of the Company. At each of March 31, 2023 and December 31, 2022 there were $61.0 million in trust preferred securities included in the Tier 2 capital of the Company for regulatory reporting purposes pursuant to the Federal Reserve's capital adequacy guidelines.

Investment Management The following table presents total assets under administration and number of accounts held by the Rockland Trust Investment Management Group at the following dates:

Table 9 - Assets Under Administration

	March 31 2023		December 31 2022		March 31 2022
	(Dollars in thousands)
Assets under administration	$	6,145,134	$	5,792,857	$	5,724,542
Number of trust, fiduciary and agency accounts	6,527		6,459		6,667

The Company's Investment Management Group provides investment management and trust services to individuals, institutions, small businesses, and charitable institutions.

Accounts maintained by the Investment Management Group consist of managed and nonmanaged accounts. Managed accounts are those for which the Bank is responsible for administration and investment management and/or investment advice, while nonmanaged accounts are those for which the Bank acts solely as a custodian or directed trustee. The Bank receives fees dependent upon the level and type of service(s) provided. The Investment Management Group generated gross fee revenues of $8.2 million and $7.9 million for the three months ended March 31, 2023 and 2022, respectively. Total assets under administration at March 31, 2023 were $6.1 billion, including $627.9 million of investment solutions designed by Rockland Trust that are administered and executed through its agreement with LPL Financial ("LPL"), compared to $5.8 billion and $603.7 million, respectively, at December 31, 2022. The Company also has a subsidiary that is a registered investment advisor, Bright Rock Capital Management, LLC ("Bright Rock"), which provides institutional quality investment management services to both institutional and high net worth clients. Included in these same amounts as of March 31, 2023 and December 31, 2022 are assets under administration of $411.6 million and $390.1 million, respectively, related to Bright Rock.

The administration of trust and fiduciary accounts is monitored by the Trust Committee of the Bank’s Board of Directors. The Trust Committee has delegated administrative responsibilities to three committees, one for investments, one for administration, and one for operations, all of which are comprised of Investment Management Group officers who meet no less than quarterly.

The Bank has an agreement with LPL and its affiliates and their insurance subsidiary, LPL Insurance Associates, Inc., to offer the sale of mutual fund shares, unit investment trust shares, general securities, fixed and variable annuities and life insurance. Registered representatives who are both employed by the Bank and licensed and contracted with LPL are onsite to

69

offer these products to the Bank’s customer base. These same agents are also approved and appointed with various other Broker General Agents for the purposes of processing insurance solutions for clients. Retail investments and insurance revenue was $1.6 million and $769,000 for the three months ended March 31, 2023 and 2022, respectively.

RESULTS OF OPERATIONS

    The following table provides a summary of results of operations for the three months ended March 31, 2023 and 2022:

Table 10 - Summary of Results of Operations

	Three Months Ended March 31
	2023			2022
	(Dollars in thousands, except per share data)
Net income	$	61,247		$	53,097
Diluted earnings per share	$	1.36		$	1.12
Return on average assets	1.30		%	1.06		%
Return on average equity	8.63		%	7.16		%
Net interest margin	3.79		%	3.09		%

Net Interest Income The amount of net interest income is affected by changes in interest rates and by the volume, mix, and interest rate sensitivity of interest-earning assets and interest-bearing liabilities.

On a fully tax equivalent basis ("FTE"), net interest income for the first quarter of 2023 was $160.1 million, representing an increase of $21.7 million, or 15.7%, when compared to the first quarter of 2022. The year-over-year increase in net interest income was primarily attributable to the positive impact of asset repricing in the rising rate environment, partially offset by higher funding costs from elevated deposit pricing in comparison to the same prior year quarter, as well as increased borrowings assumed by the Company during the quarter ended March 31, 2023.

71

The following tables present the Company’s average balances, net interest income, interest rate spread, and net interest margin for the three months ended March 31, 2023 and 2022. Nontaxable income from loans and securities is presented on a FTE basis by adjusting tax-exempt income upward by an amount equivalent to the prevailing income tax rate that would have been paid if the income had been fully taxable.

Provision For Credit Losses The provision for credit losses represents the charge to expense that is required to maintain an appropriate level of allowance for credit losses. The Company recorded a $7.3 million and a $2.0 million provision for credit losses for the three months ended March 31, 2023 and March 31, 2022, respectively. The provision for credit losses for the three months ended March 31, 2023 primarily reflects an additional reserve allocation associated with further credit deterioration of a large commercial and industrial credit that migrated to nonperforming status during 2022, resulting in a full specific reserve allocation on the loan. The Company’s allowance for credit losses as a percentage of total loans, was 1.14%, 1.09%, and 1.06% at March 31, 2023, December 31, 2022, and March 31, 2022, respectively. The Company recorded net charge-offs of $538,000 for the three months ended March 31, 2023, as compared to net charge-offs of $404,000 for the three months ended March 31, 2022. Refer to Note 4 "Loans, Allowance for Credit Losses and Credit Quality" within the Notes to Consolidated Financial Statements included in Part I. Item 1 of this Report, for further details surrounding the primary drivers of the provision for credit losses for the period.

Noninterest Income The following table sets forth information regarding noninterest income for the periods shown:

Total	$	28,242	$	26,272	$	1,970	7.50	%

The primary reasons for the variances in the noninterest income categories shown in the preceding table include:

•Deposit account fees increased driven primarily by increased overdraft fees.

•Interchange and ATM fees increased due to higher debit card service charges.

•Investment management income increased driven primarily by higher levels of assets under administration, which increased by $420.6 million, or 7.3%, to $6.1 billion at March 31, 2023 as compared to $5.7 billion at March 31, 2022, as well as higher retail and insurance commission income during the first quarter of 2023.

•Mortgage banking income decreased for the three months ended March 31, 2023 in comparison to the prior year period, primarily reflecting overall reduced volumes from rising interest rates.

•Loan level derivative income decreased primarily due to lower customer demand.

•Other noninterest income increased for the three months ended March 31, 2023, primarily attributable to increases in rental income from equipment leases, unrealized gains on equity securities and credit card fee income.

75

Noninterest Expense The following table sets forth information regarding non-interest expense for the periods shown:

Table 14 - Noninterest Expense

	Three Months Ended

Total	$	98,661	$	95,500	$	3,161	3.31	%

The primary reasons for the variances in the noninterest expense categories shown in the preceding table include:

•The increase in salaries and employee benefits was primarily attributable to CEO transition related expenses, general salary increases and payroll taxes.

•Occupancy and equipment expenses decreased, driven primarily by reduced snow removal costs costs and equipment maintenance and repairs, partially offset by increased utilities expenses.

•Consulting expense increased for the three months ended March 31, 2023, due primarily to the Company's overall growth and implementation of strategic initiatives.

•Software maintenance increased primarily due to the Company's continued investment in its technology infrastructure.

•Debit card expense increased due to higher processing fees driven by volume.

•FDIC assessment increased primarily due to increased assessment rates.

•The Company incurred merger and acquisition costs related to the Meridian acquisition of $7.1 million during the first quarter of 2022, primarily related to lease terminations associated with exited branch locations, along with additional integration costs and professional fees. No such costs were incurred during the first quarter of 2023.

•Other noninterest expense increased for the three months ended March 31, 2023, primarily due to increases in legal fees and timing of expenses such as trainings, subscriptions and recruitment, which are tied to various strategic initiatives, offset partially by decreases in unrealized losses on equity securities.

Income Taxes The tax effect of all income and expense transactions is recognized by the Company in each year’s consolidated statements of income, regardless of the year in which the transactions are reported for income tax purposes. The following table sets forth information regarding the Company’s tax provision and applicable tax rates for the periods indicated:

76

Table 15 - Tax Provision and Applicable Tax Rates

	Three Months Ended
	March 31
	2023			2022
	(Dollars in thousands)
Combined federal and state income tax provision	$	20,082		$	17,107
Effective income tax rate	24.69		%	24.37		%
Blended statutory tax rate	27.85		%	27.11		%

The Company’s effective tax rate in 2023 thus far is higher as compared to the year ago period primarily due to higher pre-tax income. The effective tax rates in the table above are lower than the blended statutory tax rates due to the impact of discrete items, including tax benefits related to low income housing tax credits and equity compensation, as well as certain tax preference assets such as life insurance policies, tax exempt bonds, and federal tax credits.

The Company invests in various low income housing projects, which are real estate limited partnerships that acquire, develop, own and operate low and moderate-income housing developments. As a limited partner in these operating partnerships, the Company will receive tax credits and tax deductions for losses incurred by the underlying properties. The investments are accounted for using the proportional amortization method and will be amortized over various periods through 2039, which represents the period that the tax credits and other tax benefits will be utilized. The total committed investment in these partnerships is $197.7 million, of which $152.9 million had been funded as of March 31, 2023. It is expected that the limited partnership investments will generate a net tax benefit of approximately $3.6 million for the fiscal year 2023 and a total of $22.1 million over the remaining life of the investments from the combination of the tax credits and operating losses.

Risk Management

The Board of Directors has approved an Enterprise Risk Management Policy to state the Company’s goals and objectives in identifying, measuring, and managing the risks associated with the Company’s current and near future anticipated size and complexity. Management is responsible for comprehensive enterprise risk management, and continually strives to adopt and implement practices that strike an appropriate balance between risk and reward and permit the achievement of strategic goals in a controlled environment.

The Company has implemented the “three lines of defense” enterprise risk management model. The first line of defense are the executives in charge of business units, operational areas, and corporate functions who, sometimes assisted by management committees, teams, and working groups, own and manage risks. The second line of defense monitors and provides risk management advice across all risk domains, and is comprised of the enterprise risk department, with oversight from the Chief Risk Officer. The third line of defense is independent assurance performed by the Chief Internal Auditor, who reports to the Audit Committee of the Company's Board of Directors, and by the Company's internal audit department.

The Board of Directors, with the assistance of its Risk Committee, oversees management’s enterprise risk management practices. As risks must be taken to create value, the Board of Directors has approved a Risk Appetite Statement that defines the acceptable residual risk tolerances for the Company and the nine major risk types identified as having the potential to create significant adverse impacts on the Company, such as financial losses, reputational damage, legal or regulatory actions, failure to achieve strategic objectives, diminished customer experience, and/or cultural erosion. The nine major risk types identified by the Company and addressed in the Risk Appetite Statement are strategic and emerging risk, culture risk, credit risk, liquidity risk, interest rate risk, operational risk, reputation risk, compliance risk, and technology risk, each of which is discussed below.

Strategic and Emerging Risk   Strategic and emerging risk is the risk arising from adverse strategic or business decisions, misalignment of strategic direction with the Company’s mission and values, failure to execute strategies or tactics, or an inadequate adaptation or lack of responsiveness to industry and/or operating environment changes. Management seeks to mitigate strategic risk through strategic planning, frequent executive review of strategic plan progress, monitoring of competitors and technology, assessment of new products, new branches, and new business initiatives, customer advocacy, and crisis management planning.

Culture Risk    Culture risk is the risk arising from failed leadership and/or ineffective colleague engagement and workplace management that causes the Company to lose sight of core values and, through acts or omissions, damage the relationship-based culture that has been one of the foundations of the Company’s consistent success. Management seeks to mitigate culture risk through effective employee relations, leadership that encourages continuous improvement, cultural

77

development and reinforcement of core values, communication of clear ethical and behavioral standards, consistent enforcement of policies and programs, discipline of misbehavior, alignment of incentives and compensation, and by promoting diversity, equity, and inclusion.

Credit Risk   Credit risk is the risk arising from the failure of a borrower or a counterparty to a contract to make payments as agreed, and includes the risks arising from inadequate collateral and mismanagement of loan concentrations. While the collateral securing loans may be sufficient in some cases to recover the amount due, in other cases the Company may experience significant credit losses that could have an adverse effect on its operating results. The Company makes assumptions and judgments about the collectability of its loan portfolio, including the creditworthiness of its borrowers and counterparties and the value of collateral for the repayment of loans. For further discussion regarding the credit risk and the credit quality of the Company’s loan portfolio, see Note 4, “Loans, Allowance for Credit Losses and Credit Quality” within the Notes to Consolidated Financial Statements included in Part I. Item 1 of this Report.

Liquidity Risk     Liquidity risk is the risk arising from the Company being unable to meet obligations when due. Liquidity risk includes the inability to access funding sources or manage fluctuations in available funding levels. Liquidity risk also results from a failure to recognize or address market condition changes that affect the ability to liquidate assets quickly with minimal value loss.

The Company’s primary sources of funds are deposits, borrowings, and the amortization, prepayment, and maturities of loans and securities. The Bank utilizes its extensive branch network to access retail customers who provide a base of in-market core deposits. These funds are principally comprised of demand deposits, interest checking accounts, savings accounts, and money market accounts. Interest rates, economic conditions, and competitive factors greatly influence deposit levels.

The Company’s primary measure of short-term liquidity is the Total Basic Surplus/Deficit as a percentage of assets. This ratio, which is an analysis of the relationship between liquid assets plus available FHLB funding, less short-term liabilities relative to total assets, was within policy limits at March 31, 2023. The Total Basic Surplus/Deficit measure is affected primarily by changes in deposits, securities and short-term investments, loans, and borrowings. An increase in deposits, without a corresponding increase in nonliquid assets, will improve the Total Basic Surplus/Deficit measure, whereas, an increase in loans, with no increase in deposits, will decrease the measure. Other factors affecting the Total Basic Surplus/Deficit include FHLB collateral requirements, securities portfolio changes, and the mix of deposits.

The Company prioritizes core deposits as a primary funding source. The Company experienced a decline in its deposit balances during the first quarter of 2023, attributable to various factors, including seasonality, customer balance diversification due to FDIC insurance limits, and a competitive rate environment. As a result of the deposit outflows, the Company’s Borrowings increased during the quarter. The Company continues to maintain a variety of available liquidity sources, including FHLB advances, Federal Reserve borrowing capacity, and repurchase agreement lines. These funding sources serve as a contingent source of liquidity and, when profitable lending and investment opportunities exist, the Company may access them to provide the liquidity needed to grow the balance sheet. The amount and type of assets that the Company has available to pledge affects the Company's FHLB and Federal Reserve borrowing capacity. For example, a prime one-to-four family residential loan may provide 75 cents of borrowing capacity for every $1.00 pledged, whereas a pledged commercial loan may increase borrowing capacity in a lower amount. The Company’s lending decisions, therefore, can also affect its liquidity position.

The Company may also have the ability to raise additional funds through the issuance of equity or unsecured debt privately or publicly and has done so in the past. Additionally, the Company is able to enter into repurchase agreements or acquire brokered deposits at its discretion. The availability and cost of equity or debt on an unsecured basis is dependent on many factors, including the Company’s financial position, the market environment, and the Company’s credit rating. The Company monitors the factors that could affect its ability to raise liquidity through these channels.

78

The following table depicts current and unused liquidity capacity from various sources as of the dates indicated:

(1)Loans with a carrying value of $2.7 billion at both March 31, 2023 and December 31, 2022, were pledged to the FHLB of Boston resulting in this additional unused borrowing capacity.

(2)Loans with a carrying value of $4.6 billion and $1.7 billion at March 31, 2023 and December 31, 2022, respectively, were pledged to the Federal Reserve Bank of Boston resulting in this additional unused borrowing capacity.

(3)The additional borrowing capacity has not been assessed for these categories.

In addition to customary operational liquidity practices, the Board of Directors and management recognize the need to establish reasonable guidelines to manage a heightened liquidity risk environment. Catalysts for elevated liquidity risk can be Company-specific issues and/or systemic industry-wide events. Management is therefore responsible for instituting systems and controls designed to provide advanced detection of potentially significant funding shortages, establishing methods for assessing and monitoring risk levels, and instituting responses that may alleviate or circumvent a potential liquidity crisis. Management has established a Liquidity Contingency Plan to provide a framework to detect potential liquidity problems and appropriately address them in a timely manner. In a period of perceived heightened liquidity risk, the Liquidity Contingency Plan provides for the establishment of a Liquidity Crisis Task Force to monitor the potential for a liquidity crisis and execute an appropriate response.

In response to the recent turmoil within the banking industry, the Company has continued to operate under its Liquidity Contingency Plan, resulting in various immediate action items. From a liquidity management perspective, the company proactively borrowed under its existing FHLB capacity to increase current cash on hand to improve direct on balance sheet liquidity, while also pledging additional assets to increase overall borrowing capacity. In addition, the Company has created customer communications, increased internal discussion frequency, and continues to review both on and off balance sheet liquidity sources to understand vulnerabilities through application of various stress testing scenarios and other analyses.

Interest Rate Risk  Interest rate risk is the risk arising from changes in interest rates and the value of investments due to market conditions or other external factors or events. Interest rate risk includes market risk.

Interest rate risk is the sensitivity of income to changes in interest rates. Interest rate changes, as well as fluctuations in the level and duration of assets and liabilities, affect net interest income, the Company’s primary source of revenue. Interest rate risk arises directly from the Company’s core banking activities. In addition to directly affecting net interest income, changes in the level of interest rates can also affect the amount of loans originated, the timing of cash flows on loans and securities, and the fair value of securities and derivatives, and have other effects.

Management strives to control interest rate risk within limits approved by the Board of Directors that reflect the Company’s tolerance for interest rate risk over short-term and long-term horizons. The Company attempts to manage interest rate risk by identifying, quantifying, and, where appropriate, hedging exposure. If assets and liabilities do not re-price simultaneously and in equal volume, the potential for interest rate exposure exists. It is the Company's objective to maintain stability in the growth of net interest income through the maintenance of an appropriate mix of interest-earning assets and

79

interest-bearing liabilities and, when necessary within limits management deems prudent, with off-balance sheet hedging instruments such as interest rate swaps, floors, and caps.

The Company quantifies its interest rate exposures using net interest income simulation models, as well as simpler gap analysis, and an Economic Value of Equity analysis. Key assumptions in these analyses relate to behavior of interest rates and behavior of the Company’s deposit and loan customers. The most material assumptions relate to the prepayment of mortgage assets (including mortgage loans and mortgage-backed securities) and the life and sensitivity of non-maturity deposits (e.g., demand deposit, negotiable order of withdrawal, savings, and money market accounts). In the case of prepayment of mortgage assets, assumptions are derived from published median prepayment estimates for comparable mortgage loans. The risk of prepayment tends to increase when interest rates fall. Since future prepayment behavior of loan customers is uncertain, interest rate sensitivity of loans cannot be determined with precision and actual behavior may differ from assumptions to a significant degree. Non-maturity deposits, assumptions over customer behavior, shifts in deposits categories, and magnitude of impact to the cost of deposits all may differ from what is currently anticipated by the models or analyses.

Based upon the net interest income simulation models, the Company anticipates that assets will generally re-price faster than liabilities over the long term, though short term volatility may exist depending on the current state of the overall rate cycle, as well as the pace and magnitude of interest rate changes. As a result, net interest income will be positively impacted as market rates increase and negatively impacted if market rates decrease. The Company runs several scenarios to quantify and effectively assist in managing interest rate risk, including instantaneous parallel shifts in market rates as well as gradual (12-24 months) shifts in market rates, and may also include other alternative scenarios as management deems necessary given the interest rate environment. The results of those scenarios are summarized in the following table:

The relative results of all scenarios and the impact to net interest income as they compare to the year 1 base scenario are outlined in the table below:

The results depicted in the table above are dependent on material assumptions. For instance, asymmetrical rate behavior can have a material impact on the simulation results. If competition for deposits prompts the Company to raise rates on those liabilities more quickly than is assumed in the simulation analysis without a corresponding increase in asset yields, net interest income would be negatively affected. Alternatively, if the Company were able to lag increases in deposit rates as loans re-price upward, net interest income would be positively impacted.

The most significant market factors affecting the Company’s net interest income during the year ended March 31, 2023 were the shape of the U.S. Government securities and interest rate swap yield curve, the U.S. prime interest rate, LIBOR rates, the secured overnight financing rates ("SOFR"), and interest rates offered on long-term fixed rate loans.

The Company manages the interest rate risk inherent in both its loan and borrowing portfolios by using interest rate swap agreements and interest rate caps and floors. An interest rate swap is an agreement in which one party agrees to pay a floating rate of interest on a notional principal amount in exchange for receiving a fixed rate of interest on the same notional amount for a predetermined period from the other party. Interest rate caps and floors are agreements where one party agrees to pay a floating rate of interest on a notional principal amount for a predetermined period to a second party if certain market interest rate thresholds are realized. While interest is paid or received in swap, cap, and floors agreements, the notional principal amount is not exchanged. The Company may also manage the interest rate risk inherent in its mortgage banking operations by entering into forward sales contracts under which the Company agrees to deliver whole mortgage loans to various investors. See Note 7, “Derivative and Hedging Activities” within the Notes to Consolidated Financial Statements included in Part I. Item 1 of this Report for additional information regarding the Company’s derivative financial instruments.

Movements in foreign currency rates or commodity prices do not directly or materially affect the Company's earnings. Movements in equity prices may have a modest impact on earnings by affecting the volume of activity or the amount of fees from investment-related business lines. See Note 3, “Securities” within the Notes to Consolidated Financial Statements included in Part I. Item 1 of this Report.

Operational Risk     Operational risk is the risk arising from human error or misconduct, transaction errors or delays, inadequate or failed internal systems or processes, data unavailability, loss, or poor quality, or adverse external events. Operational risk includes fraud risk and model risk. Potential operational risk exposure exists throughout the Company. The continued effectiveness of colleagues and operational infrastructure are integral to mitigating operational risk, and any shortcomings subject the Company to risks that vary in size, scale and scope.

Reputation Risk Reputation risk is the risk arising from negative public opinion of the Company and the Bank. Management seeks to mitigate reputational risk through actions that include a structured process of customer complaint resolution and ongoing reputational monitoring.

Compliance Risk Compliance risk is the risk arising from violations of laws or regulations, non-conformance with prescribed practices, internal bank policies and procedures, or ethical standards. Compliance risk includes consumer compliance risk, legal risk, and regulatory compliance risk. Management seeks to mitigate compliance risk through compliance training and regulatory change management processes.

Technology Risk      Technology risk is the risk of losses or other impacts arising from the failure of technology systems to function in accordance with expectations and business requirements. Technology risk includes information technology risk, information security risk, and cyber security. Technology risks include technical failures, unlawful tampering with technical systems, cyber security, terrorist activities, ineffectiveness or exposure due to interruption in third party support. Management seeks to mitigate technology risk through appropriate security and controls over data and its technological environment.

Contractual Obligations, Commitments, Contingencies, and Off-Balance Sheet Financial Information

Off-Balance Sheet Arrangements There were no material changes in off-balance sheet arrangements during the three months ended March 31, 2023.

See Note 7, "Derivative and Hedging Activities" and Note 11, "Commitments and Contingencies" within the Notes to Consolidated Financial Statements included in Part I. Item 1 of this Report for more information relating to the Company's other off-balance sheet financial instruments.

Contractual Obligations, Commitments, and Contingencies There were no material changes in contractual obligations, commitments, or contingencies during the three months ended March 31, 2023.

Item 4. Controls and Procedures

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures.  The Company carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer along with the Company’s Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures, as such term is defined under Rules 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended. Based upon that evaluation, the Company’s Chief Executive Officer along with the Company’s Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of the end of the period covered by this quarterly report.

Changes in Internal Control over Financial Reporting. There were no changes in the Company's internal control over financial reporting that occurred during the first quarter of 2023 that have materially affected or are reasonably likely to materially affect the Company’s internal control over financial reporting.

PART II. OTHER INFORMATION

Item  1. Legal Proceedings

At March 31, 2023, the Bank was involved in pending lawsuits that arose in the ordinary course of business. Management has reviewed these pending lawsuits with legal counsel and has taken into consideration the view of counsel as to their outcome. In the opinion of management, the final disposition of pending lawsuits is not expected to have a material adverse effect on the Company’s financial position or results of operations.

Item 1A. Risk Factors

    The section titled Risk Factors in Part I, Item 1A of the 2022 Form 10-K includes a discussion of the material risks and uncertainties the Company faces, any one or more of which could have a material adverse effect on the Company's business, results of operations, or financial condition (including capital and liquidity). The information presented below provides an update to, and should be read in conjunction with, the risk factors and other information contained in the 2022 Form 10-K.

Except as presented below, there have been no material changes to the risk factors described in the 2022 Form 10-K.

Risks Related to Recent Events Impacting the Financial Services Industry

Recent events impacting the financial services industry, including several high profile bank failures, have resulted in decreased confidence in banks among depositors, investors and other counterparties, as well as significant disruption, volatility and depressed valuations of equity and other securities of banks in the capital markets. These events occurred during a period of rapidly rising interest rates which, among other things, has resulted in increased unrealized losses on certain investment securities, increased competition for bank deposits and may increase the risk of a potential recession. These recent events have, and could continue to adversely impact the market price and volatility of the Company’s common stock. These recent events may also result in potentially adverse changes to laws or regulations applicable to the Company, which could have a material impact on the Company’s business and result in increased costs necessary to comply with any such changes. Additionally, the cost of resolving recent bank failures may prompt the FDIC to increase its premiums above the current levels or result in additional special assessments.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Organization, Consolidation and Presentation of Financial Statements [Abstract]

BASIS OF PRESENTATION

BASIS OF PRESENTATION

Independent Bank Corp. (the “Company”) is a state chartered, federally registered bank holding company, incorporated in 1985. The Company is the sole stockholder of Rockland Trust Company (“Rockland Trust” or the “Bank”), a Massachusetts trust company chartered in 1907.

All material intercompany balances and transactions have been eliminated in consolidation. Certain previously reported amounts have been reclassified to conform to the current year’s presentation.

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation of the financial statements, primarily consisting of normal recurring adjustments, have been included. Results for the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023 or any other interim period.

For further information, refer to the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, filed with the Securities and Exchange Commission (the "2022 Form 10-K").

Recent Accounting Standards [Abstract]
RECENT ACCOUNTING STANDARDS	RECENT ACCOUNTING STANDARDS UPDATES     Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 848 "Reference Rate Reform" Update No. 2020-04. Update No. 2020-04 was issued in March 2020 to provide optional expedients and exceptions for applying GAAP to certain contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this update apply only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate ("LIBOR") or another reference rate expected to be discontinued because of reference rate reform. The amendments will not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022 for which an entity has elected certain optional expedients that are retained through the end of the hedging relationship. The amendments in this update are effective for all entities as of March 12, 2020 through December 31, 2022 and do not apply to contract modifications made after December 31, 2022. FASB ASC Topic 848 "Reference Rate Reform" Update No. 2021-01 was subsequently issued in January 2021 and expanded application of the optional expedients to derivative transactions affected by the discounting transition. The Company has not yet adopted the amendments in these updates, but has established a working group to guide the Company’s transition from LIBOR and has begun efforts to transition off the LIBOR index consistent with industry timelines. The working group has identified its products that utilize LIBOR and has implemented fallback language to facilitate the transition to alternative rates. The Company is also evaluating existing platforms and systems as well as alternative indices in its preparation to offer new products tied to the alternative indices. The Company does not anticipate that the adoption of these updates will have a material impact on the Company's financial statements.

Excluded from the table above is accrued interest on available for sale securities of $3.2 million and $3.6 million at March 31, 2023 and December 31, 2022, respectively, which is included within other assets on the consolidated balance sheets. Additionally, the Company did not record any write-offs of accrued interest income on available for sale securities during the three months ended March 31, 2023 and 2022. Furthermore, no securities held by the Company were delinquent on contractual payments nor were any securities placed on non-accrual status at March 31, 2023 and December 31, 2022.

When securities are sold, the adjusted cost of the specific security sold is used to compute the gain or loss on the sale. The Company had no sales of securities available for sale during the three months ended March 31, 2023 and 2022, and therefore no gains or losses were realized during the periods presented.

The following tables show the gross unrealized losses and fair value of the Company’s available for sale securities in an unrealized loss position, and for which the Company has not recorded a provision for credit losses, as of the dates indicated. These available for sale securities are aggregated by major security type and length of time that individual securities have been in a continuous unrealized loss position:

The Company does not intend to sell these investments and has determined, based upon available evidence, that it is more likely than not that the Company will not be required to sell each security before the recovery of its amortized cost basis. In addition, management does not believe that any of the securities are impaired due to reasons of credit quality. As a result, the Company did not recognize a provision for credit losses on these investments during the three months ended March 31, 2023 and 2022. The Company made this determination by reviewing various qualitative and quantitative factors regarding each investment category, such as current market conditions, extent and nature of changes in fair value, issuer rating changes and trends, volatility of earnings, and current analysts’ evaluations.

As a result of the Company’s review of these qualitative and quantitative factors, the causes of the impairments listed in the table above by category were as follows at March 31, 2023:

•U.S. Government Agency Securities, U.S. Treasury Securities, Agency Mortgage-Backed Securities, Agency Collateralized Mortgage Obligations and Small Business Administration Pooled Securities: These portfolios have contractual terms that generally do not permit the issuer to settle the securities at a price less than the current par value of the investment. The decline in market value of these securities is attributable to changes in interest rates and not credit quality. Additionally, these securities are implicitly guaranteed by the U.S. Government or one of its agencies.

•Pooled Trust Preferred Securities: This portfolio consists of one below investment grade security which is performing. The unrealized loss on this security is attributable to the illiquid nature of the trust preferred market in the current economic and regulatory environment. Management evaluates collateral credit and instrument structure, including current and expected deferral and default rates and timing. In addition, discount rates are determined by evaluating comparable spreads observed currently in the market for similar instruments.

Held to Maturity Securities

The following table summarizes the amortized cost, fair value and allowance for credit losses of held to maturity securities and the corresponding amounts of gross unrealized gains and losses recognized at the dates indicated:

Substantially all held to maturity securities held by the Company are guaranteed by the U.S. federal government or other government sponsored agencies and have a long history of no credit losses. As a result, management has determined these securities to have a zero loss expectation and therefore the Company did not record a provision for estimated credit losses on any held to maturity securities during the three months ended March 31, 2023 and 2022. Excluded from the table above is accrued interest on held to maturity securities of $4.5 million and $4.4 million as of March 31, 2023 and December 31, 2022, respectively, which is included within other assets on the consolidated balance sheets. Additionally, the Company did not record any write-offs of accrued interest income on held to maturity securities during the three months ended March 31, 2023 and 2022. Furthermore, no securities held by the Company were delinquent on contractual payments nor were any securities placed on non-accrual status at March 31, 2023 and December 31, 2022.

While management has the positive intent and ability to hold the Company's held to maturity securities until maturity, if a decision were made to sell a security within this portfolio, the adjusted cost of the specific security sold would be used to compute the gain or loss on the sale. The Company had no sales of held to maturity securities during the three months ended March 31, 2023 and 2022, and therefore no gains or losses were realized during the periods presented.

The Company monitors the credit quality of held to maturity securities through the use of credit ratings. Credit ratings are monitored by the Company on at least a quarterly basis. As of March 31, 2023, all held to maturity securities held by the Company were rated investment grade or higher.

The actual maturities of certain available for sale or held to maturity securities may differ from the contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. A schedule of the contractual maturities of available for sale and held to maturity securities as of March 31, 2023 is presented below:

(1)Balances of accrued interest receivable excluded from amortized cost and the calculation of allowance for credit losses amounted to $52.7 million and $39.4 million as of March 31, 2023 and March 31, 2022, respectively.

The balance of allowance for credit losses increased to $159.1 million as of March 31, 2023 compared to $152.4 million at December 31, 2022, due primarily to an additional reserve allocation associated with further credit deterioration of a large commercial and industrial credit that migrated to nonperforming status during 2022, resulting in a full specific reserve allocation on the loan.

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 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 and 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 and other specific use properties.  Loans may be written with nonamortizing 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 it is the Company’s policy to obtain 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 owner-occupied 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 restructure 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 of 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.

•Potential Weakness: 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.

•Definite Weakness Loss Unlikely: 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.

•Partial Loss Probable: 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.

•Definite 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.

The following table details the amortized cost balances of the Company's loan portfolios, presented by credit quality indicator and origination year as of the dates indicated below:

(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)Loans originated as part of the Paycheck Protection Program ("PPP") established by the Coronavirus Aid, Relief and Economic Security Act (the "CARES Act")t are included within commercial and industrial under the 2021 and 2020 vintage year and "pass" category as these loans are 100% guaranteed by the U.S. Government. Outstanding PPP loans totaled $6.6 million and $99.6 million as of March 31, 2023 and 2022, respectively.

(3)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 2023		December 31 2022
Residential real estate portfolio
FICO score (re-scored)(1)	752		753
LTV (re-valued)(2)	58.7	%	57.0	%
Home equity portfolio
FICO score (re-scored)(1)	771		771
LTV (re-valued)(2)(3)	43.8	%	41.3	%

(1)The average FICO scores at March 31, 2023 are based upon rescores from March 2023, as available for previously originated loans, or origination score data for loans booked in March 2023.  The average FICO scores at December 31, 2022 were based upon rescores available from December 2022, as available for previously originated loans, or origination score data for loans booked in December 2022.

(2)The combined LTV ratios for March 31, 2023 are based upon updated automated valuations as of February 2023, when available, and/or the most current valuation data available.  The combined LTV ratios for December 31, 2022 were based upon updated automated valuations as of November 2022, when available, and/or the most current valuation data available as of such date.  The updated automated valuations provide new information on loans that may be available since the previous valuation was obtained.  If no new information is available, the valuation will default to the previously obtained data or most recent appraisal.

(3)For home equity loans and lines in a subordinate lien, the LTV data represents a combined LTV, taking into account the senior lien data for loans and lines.

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, 2023 and December 31, 2022, the Company's estimated reserve for unfunded commitments amounted to $1.6 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:

Loan Modifications

In the course of resolving nonperforming loans, the Company may choose to restructure the contractual terms of certain loans. The Company attempts to work out an alternative payment schedule with the borrower in order to avoid foreclosure actions. Terms may be modified to fit the ability of the borrower to repay in line with its current financial status and the restructuring of the loan may include principal forgiveness, interest rate reductions, term extensions, other-than-insignificant payment delays, and/or any combinations thereof. Any loans that are modified are reviewed by the Company to determine whether the modification is the direct result of a borrower experiencing financial difficulty, as the Company adopted the accounting and disclosure requirements for loan modifications made to borrowers experiencing financial difficulty and ceased to recognize TDRs effective January 1, 2023.

Loan modifications made 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. Under previously applicable accounting guidance, the Company determined the amount of allowance for credit losses on TDRs using a discounted cash flow analysis or a fair value of collateral approach if the loan was determined to be individually evaluated. This change in methodology did not have a material impact on the Company's allowance for credit loss estimate.

The following table presents the amortized cost basis at March 31, 2023 of loans modified to borrowers experiencing financial difficulty during the three month period then ended, disaggregated by class of financing receivable and type of modification granted:

	Term Extension
	Amortized Cost Basis		% of Total Class of Financing Receivable

The following table describes the financial effect of the modifications made to borrowers experiencing financial difficulty for the period ending March 31, 2023:

Term Extension
Loan Category	Financial Effect
Commercial real estate	Added a weighted-average contractual term of 2 months to the life of the loan, which reduced monthly payment amounts for the borrowers.
Small business	Added a weighted-average contractual term of 4.3 years to the life of loans, which reduced monthly payment amounts for the borrowers.
Interest Rate Reduction
Loan Category	Financial Effect
Small business	Reduced weighted-average contractual interest rate from 10.00% to 6.50%

The following table shows the Company’s total TDRs and other pertinent information as of the date indicated:

		December 31, 2022
	(Dollars in thousands)
TDRs on accrual status		$	11,278
TDRs on nonaccrual		11,520
Total TDRs		$	22,798

There were no new TDRs during the three months ended March 31, 2022.

At March 31, 2023, the Company did not have any additional commitments to lend to borrowers experiencing financial difficulty who were party to a loan modification. At December 31, 2022, the Company had additional commitments to lend to borrowers who had been a party to a TDR of $64,000.

The Company closely monitors the performance of loans modified to borrowers experiencing financial difficulty to understand the effectiveness of its modification efforts. The Company considers a loan to have defaulted when it reaches 90 days past due. During the three months ended March 31, 2023 there were no loans modified to borrowers experiencing financial difficulty that subsequently defaulted, and during the three months ended March 31, 2022, there were no TDRs that were modified during the prior twelve months that subsequently defaulted. Accordingly, all loans modified to borrowers experiencing financial difficulty during the period remained current and were performing in accordance with the modified terms as of March 31, 2023.

Derivatives and Hedging Activities

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives and Fair Value

DERIVATIVE AND HEDGING ACTIVITIES

The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally to manage the Company’s interest rate risk. Additionally, the Company enters into interest rate derivatives, foreign exchange contracts and risk participation agreements to accommodate the business requirements of its customers (“customer related positions”). The Company minimizes the market and liquidity risks of customer related positions by entering into similar offsetting positions with broker-dealers. Derivative instruments are carried at fair value in the Company's financial statements. The accounting for changes in the fair value of a derivative instrument is dependent upon whether or not it qualifies as a hedge for accounting purposes, and further, by the type of hedging relationship.

The Company does not enter into proprietary trading positions for any derivatives.

The Company is subject to over-the-counter derivative clearing requirements which require certain derivatives to be cleared through central clearing houses. Accordingly, the Company clears certain derivative transactions through the Chicago Mercantile Exchange Clearing House ("CME"). This clearing house requires the Company to post initial and variation margin to mitigate the risk of non-payment, the latter of which is received or paid daily based on the net asset or liability position of the contracts.

Interest Rate Positions

The Company may utilize various interest rate derivatives as hedging instruments against interest rate risk associated with the Company’s borrowings and loan portfolios. An interest rate derivative is an agreement whereby one party agrees to pay a floating rate of interest on a notional principal amount in exchange for receiving a fixed rate of interest on the same notional amount, for a predetermined period of time, from a second party. The amounts relating to the notional principal amount are not actually exchanged.

The following tables reflect the Company's derivative positions at the dates indicated below for interest rate swaps which qualify as cash flow hedges for accounting purposes:

March 31, 2023
				Weighted Average Rate
	Notional Amount		Average Maturity	Current Rate Received		Pay Fixed Swap Rate		Fair Value
	(in thousands)		(in years)					(in thousands)
Interest rate swaps on borrowings	$	300,000	3.48	4.87	%	3.57	%	$	(202)

				Current Rate Paid		Receive Fixed Swap Rate Cap - Floor
Interest rate collars on loans	400,000		2.27	4.22	%	3.09% - 2.19%		(10,239)
Total	$	1,450,000						$	(52,244)

The maximum length of time over which the Company is currently hedging its exposure to the variability in future cash flows for forecasted transactions related to the payment of variable interest on existing financial instruments is 6.0 years.

For derivative instruments that are designated and qualify as cash flow hedging instruments, the effective portion of the gains or losses is reported as a component of other comprehensive income and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings.  The Company expects approximately $3.1 million (pre-tax) to be reclassified as an increase to interest income and $25.0 million (pre-tax) to be reclassified as an increase to interest expense, from OCI related to the Company’s cash flow hedges in the twelve months following March 31, 2023.  This reclassification is due to anticipated payments that will be made and/or received on the swaps based upon the forward curve at March 31, 2023.

The Company had no fair value hedges as of March 31, 2023 or December 31, 2022.

Customer Related Positions

Loan level derivatives, primarily interest rate swaps, offered to commercial borrowers through the Company’s loan level derivative program do not qualify as hedges for accounting purposes. The Company believes that its exposure to commercial customer derivatives is limited because these contracts are simultaneously matched at inception with an offsetting dealer transaction. Derivatives with dealer counterparties are then either cleared through a clearinghouse or settled directly with a single counterparty. The commercial customer derivative program allows the Company to retain variable-rate commercial loans while allowing the customer to synthetically fix the loan rate by entering into a variable-to-fixed interest rate swap. The amounts relating to the notional principal amount are not actually exchanged.

Foreign exchange contracts offered to commercial borrowers through the Company’s derivative program do not qualify as hedges for accounting purposes. The Company acts as a seller and buyer of foreign exchange contracts to accommodate its customers. To mitigate the market and liquidity risk associated with these derivatives, the Company enters into similar offsetting positions. The amounts relating to the notional principal amount are exchanged.

The Company has entered into risk participation agreements with other dealer banks in commercial loan agreements. Participating banks guarantee the performance on borrower-related interest rate swap contracts. These derivatives are not designated as hedges and, therefore, changes in fair value are recognized in earnings. Under a risk participation-out agreement, a derivative asset, the Company participates out a portion of the credit risk associated with the interest rate swap position executed with the commercial borrower for a fee paid to the participating bank. Under a risk participation-in agreement, a derivative liability, the Company assumes, or participates in, a portion of the credit risk associated with the interest rate swap position with the commercial borrower for a fee received from the other bank.

The following table reflects the Company’s customer related derivative positions at the dates indicated below for those derivatives not designated as hedging:

(1)The Company may enter into one dealer swap agreement which offsets multiple commercial borrower swap agreements.

Mortgage Derivatives

The Company enters into commitments to fund residential mortgage loans at specified rates and times in the future, with the intention that loans may be sold subsequently in the secondary market. Mortgage loan commitments are referred to as derivative loan commitments if the loan that will result from exercise of the commitment will be held for sale upon funding. These commitments are recognized at fair value on the consolidated balance sheet in other assets and other liabilities with changes in their fair values recorded within mortgage banking income. In addition, the Company has elected the fair value option to carry loans held for sale at fair value. The change in fair value of loans held for sale is recorded in current period earnings as a component of mortgage banking income in accordance with the Company's fair value election. The change in fair value associated with loans held for sale was a decrease of $17,000 and $548,000 for the three months ended March 31, 2023 and 2022, respectively. These amounts were offset in earnings by the change in the fair value of mortgage derivatives.

Outstanding loan commitments expose the Company to the risk that the price of the loans arising from exercise of the loan commitment might change from inception of the rate lock to funding of the loan due to changes in mortgage interest rates. If interest rates increase, the value of these loan commitments decreases. Conversely, if interest rates decrease, the value of these loan commitments increases. To protect against the price risk inherent in derivative loan commitments, the Company utilizes both "mandatory delivery" and "best efforts" forward loan sale commitments to mitigate the risk of potential decreases in the values of loans that would result from the exercise of the derivative loan commitments. Mandatory delivery contracts are accounted for as derivative instruments. Included in the mandatory delivery forward commitments are To Be Announced securities ("TBAs"). Certain assumptions, including pull through rates and rate lock periods, are used in managing the existing and future hedges. The accuracy of underlying assumptions will impact the ultimate effectiveness of any hedging strategies.

With mandatory delivery contracts, the Company commits to deliver a certain principal amount of mortgage loans to an investor at a specified price on or before a specified date. If the Company fails to deliver the amount of mortgages necessary to fulfill the commitment by the specified date, it is obligated to pay a "pair-off" fee, based on then-current market prices, to the investor/counterparty to compensate the investor for the shortfall. Generally, the Company makes this type of commitment once mortgage loans have been funded and are held for sale, in order to minimize the risk of failure to deliver the requisite volume of loans to the investor and paying pair-off fees as a result. The Company also sells TBA securities to offset potential changes in the fair value of derivative loan commitments. Generally, the Company sells TBA securities by entering into derivative loan commitments for settlement in 30 to 90 days. The Company expects that mandatory delivery contracts, including TBA securities, will experience changes in fair value opposite to the changes in the fair value of derivative loan commitments.

With best effort contracts, the Company commits to deliver an individual mortgage loan of a specified principal amount and quality to an investor if the loan to the underlying borrower closes. Generally, best efforts cash contracts have no pair off risk regardless of market movement. The price the investor will pay the seller for an individual loan is specified prior to the loan being funded (e.g., on the same day the lender commits to lend funds to a potential borrower). The Company expects that these best efforts forward loan sale commitments will experience a net neutral shift in fair value with related derivative loan commitments.

The aggregate amount of net realized gains on sales of such loans included within mortgage banking income was $174,000 and $599,000 for the three months ended March 31, 2023 and 2022, respectively.

Balance Sheet Offsetting

The Company does not offset fair value amounts recognized for derivative instruments. The Company does net the amount recognized for the right to reclaim cash collateral against the obligation to return cash collateral arising from derivative instruments executed with the same counterparty under a master netting arrangement. Collateral legally required to be maintained at dealer banks by the Company is monitored and adjusted as necessary.

A daily settlement occurs through the CME for changes in the fair value of centrally cleared derivatives. Not all of the derivatives are required to be cleared through the daily clearing agent. As a result, the total fair values of loan level derivative assets and liabilities recognized on the Company's financial statements are not equal and offsetting.

The table below presents the fair value of the Company’s derivative financial instruments as well as their classification on the balance sheet and the potential effect of netting arrangements on its financial position, at the dates indicated:

    The Company's derivative agreements with institutional counterparties contain various credit-risk related contingent provisions, such as requiring the Company to maintain a well-capitalized capital position. If the Company fails to meet these conditions, the counterparties could request the Company make immediate payment or demand that the Company provide immediate and ongoing full collateralization on derivative positions in net liability positions. All derivative instruments with credit-risk contingent features were in a net asset position at March 31, 2023 and December 31, 2022.

    By using derivatives, the Company is exposed to credit risk to the extent that counterparties to the derivative contracts do not perform as required. Should a counterparty fail to perform under the terms of a derivative contract, the Company's credit exposure on interest rate swaps is limited to the net positive fair value and accrued interest of all swaps with each counterparty. The Company seeks to minimize counterparty credit risk through credit approvals, limits, monitoring procedures, and obtaining collateral, where appropriate. Institutional counterparties must have an investment grade credit rating and be approved by the Company's Board of Directors. In addition, certain derivative contracts executed bilaterally with a dealer counterparty in the over-the-counter market are cleared through a clearinghouse, whereby the clearinghouse becomes the counterparty to the transaction. As such, management believes the risk of incurring credit losses on derivative contracts with those counterparties is remote. The Company's exposure relating to institutional counterparties was $95.3 million and $121.2 million at March 31, 2023 and December 31, 2022, respectively. The Company’s exposure relating to customer counterparties was approximately $5.9 million and $2.2 million at March 31, 2023 and December 31, 2022, respectively. Credit exposure may be reduced by the value of collateral pledged by the counterparty.

Fair Value Measurements

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

Fair value is a market-based measure considered from the perspective of a market participant rather than an entity-specific measure. Therefore, even when market assumptions are not readily available, the assumptions applied by the Company when determining fair value reflect those that the Company determines market participants would use to price the asset or liability at the measurement date. If there has been a significant decrease in the volume and level of activity for the asset or liability, regardless of the valuation technique(s) used, the objective of a fair value measurement remains the same. Fair value is the price that would be received if the asset were to be sold or that would be paid if the liability were to be transferred in an orderly market transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. When determining fair value, the Company considers pricing information and other inputs that are current as of the measurement date. In periods of market dislocation, the observability of prices and other inputs may be reduced for certain instruments, or not available at all. The unavailability or reduced availability of pricing or other input information could cause an instrument to be reclassified from one level to another.

The Fair Value Measurements and Disclosures Topic of the FASB ASC defines fair value and establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under the Fair Value Measurements and Disclosures Topic of the FASB ASC are described below:

Level 1 – Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level 2 – Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.

Level 3 – Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.

To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

Valuation Techniques

There were no changes in the valuation techniques used during the three months ended March 31, 2023.

Securities

Trading and Equity Securities

These equity securities are valued based on market quoted prices. These securities are categorized in Level 1 as they are actively traded and no valuation adjustments have been applied.

U.S. Government Agency and U.S. Treasury Securities

Fair value is estimated using either multi-dimensional spread tables or benchmarks. The inputs used include benchmark yields, reported trades, and broker/dealer quotes. These securities are classified as Level 2.

Agency Mortgage-Backed Securities

Fair value is estimated using either a matrix or benchmarks. The inputs used include benchmark yields, reported trades, broker/dealer quotes, and issuer spreads. These securities are categorized as Level 2.

Agency Collateralized Mortgage Obligations and Small Business Administration Pooled Securities

The valuation model for these securities is volatility-driven and ratings based, and uses multi-dimensional spread tables. The inputs used include benchmark yields, reported trades, new issue data, broker dealer quotes, and collateral performance. If there is at least one significant model assumption or input that is not observable, these securities are categorized as Level 3 within the fair value hierarchy; otherwise, they are classified as Level 2.

State, County, and Municipal Securities

The fair value is estimated using a valuation matrix with inputs including bond interest rate tables, recent transactions, and yield relationships. These securities are categorized as Level 2.

Single and Pooled Issuer Trust Preferred Securities

The fair value of trust preferred securities, including pooled and single issuer preferred securities, is estimated using external pricing models, discounted cash flow methodologies or similar techniques. The inputs used in these valuations include benchmark yields, reported trades, new issue data, broker dealer quotes, and collateral performance. If there is at least one significant model assumption or input that is not observable, these securities are classified as Level 3 within the fair value hierarchy; otherwise, they are classified as Level 2.

Loans Held for Sale

The Company has elected the fair value option to account for originated closed loans intended for sale. The fair value is measured on an individual loan basis using quoted market prices and when not available, comparable market value or discounted cash flow analysis may be utilized. These assets are typically classified as Level 2.

Derivative Instruments

Derivatives

The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The Company incorporates credit valuation adjustments to appropriately reflect nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings. Additionally, in conjunction with fair value measurement guidance, the Company has made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio. Although the Company has determined that the majority of the inputs used to value its interest rate derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its interest rate derivatives and risk participation agreements may also utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties. However, as of March 31, 2023 and December 31, 2022, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are properly classified as Level 2.

Mortgage Derivatives

The fair value of mortgage derivatives is determined based on current market prices for similar assets in the secondary market and, therefore, classified as Level 2 within the fair value hierarchy.

Individually Assessed Collateral Dependent Loans

In accordance with the CECL standard, expected credit losses on individually assessed loans deemed to be collateral dependent are valued based upon the lower of amortized cost or fair value of the underlying collateral less costs to sell.  The inputs used in the appraisals of the collateral are not always observable, and in such cases the loans may be classified as Level 3 within the fair value hierarchy; otherwise, they are classified as Level 2.

Other Real Estate Owned and Other Foreclosed Assets

Other Real Estate Owned ("OREO") and Other Foreclosed Assets, when applicable, are valued at the lower of cost or fair value of the property, less estimated costs to sell. The fair values are generally estimated based upon recent appraisal values of the property less costs to sell the property. Certain inputs used in appraisals are not always observable, and therefore OREO and Other Foreclosed Assets may be classified as Level 3 within the fair value hierarchy.

Goodwill and Other Intangible Assets

Goodwill and other intangible assets are subject to impairment testing. The Company conducts an annual impairment test of goodwill in the third quarter of each year, or more frequently if necessary. Other intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. To estimate the fair value of goodwill and, if necessary, other intangible assets, the Company utilizes both a comparable analysis of relevant price multiples in recent market transactions and a discounted cash flow analysis. Both valuation models require a significant degree of management judgment. In the event the fair value as determined by the valuation model is less than the carrying value, the intangibles may be impaired. If the impairment testing resulted in impairment, the Company would classify the impaired goodwill and other intangible assets subjected to nonrecurring fair value adjustments as Level 3.

Assets and liabilities measured at fair value on a recurring and nonrecurring basis were as follows at the dates indicated:

(1) The carrying value of individually assessed collateral dependent loans is based on the lower of amortized cost or fair value of the underlying collateral less costs to sell. The fair value of the underlying collateral is generally determined through independent appraisals, which generally include various Level 3 inputs which are not identifiable. Appraisals may be adjusted by management for qualitative factors such as economic factors and estimated liquidation expenses. The range of these possible adjustments may vary.

(b)Fair value of loans is measured using the exit price valuation method, determined primarily by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities or cash flows, while incorporating liquidity and credit assumptions. Additionally, this amount excludes individually assessed collateral dependent loans, which are deemed to be marked to fair value on a nonrecurring basis.

(c)FHLB stock has no quoted market value and is carried at cost; therefore, the carrying amount approximates fair value.

(d)Cash surrender value of life insurance policies is recorded at its cash surrender value (or the amount that can be realized upon surrender of the policy), therefore, carrying amount approximates fair value.

(e)Fair value of demand deposits, savings and interest checking accounts and money market deposits is the amount payable on demand at the reporting date.

(f)Fair value was determined by discounting anticipated future cash payments using rates currently available for instruments with similar remaining maturities.

(g)Fair value was determined based upon market prices of securities with similar terms and maturities.

This summary excludes certain financial assets and liabilities for which the carrying value approximates fair value. For financial assets, these may include cash and due from banks, federal funds sold and short-term investments. For financial liabilities, these may include federal funds purchased. These instruments would all be considered to be classified as Level 1 within the fair value hierarchy. Also excluded from the summary are financial instruments measured at fair value on a recurring and nonrecurring basis, as previously described.

The Company considers its current use of financial instruments to be the highest and best use of the instruments.

Revenue Recognition [Abstract]

Revenue from Contract with Customer [Text Block]

REVENUE RECOGNITION

A portion of the Company's noninterest income is derived from contracts with customers, and as such, the revenue recognized depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company accounts for such revenues in accordance with ASC 606 - Revenue from Contracts with Customers considers the terms of the contract and all relevant facts and circumstances when applying this guidance. To ensure its alignment with this core principle, the Company measures revenue and the timing of recognition by applying the following five steps:

1.Identify the contract(s) with customers

2.Identify the performance obligations

3.Determine the transaction price

4.Allocate the transaction price to the performance obligations

5.Recognize revenue when (or as) the entity satisfies a performance obligation

The Company has disaggregated its revenue from contracts with customers into categories that depict how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. The following table presents the revenue streams that the Company has disaggregated as of the periods indicated:

	Three Months Ended
	March 31 2023		March 31 2022
	(Dollars in thousands)
Deposit account fees (inclusive of cash management fees)	$	5,916	$	5,493
Interchange fees	2,788		2,472
ATM fees	938		841
Investment management - wealth management and advisory services	8,185		7,904
Investment management - retail investments and insurance revenue	1,594		769
Merchant processing income	470		378
Credit card income	493		372
Other noninterest income	1,198		1,396
Total noninterest income in-scope of ASC 606	21,582		19,625
Total noninterest income out-of-scope of ASC 606	6,660		6,647
Total noninterest income	$	28,242	$	26,272

In each of the revenue streams identified above, there were no significant judgments made in determining or allocating the transaction price, as the consideration and service requirements are generally explicitly identified in the associated contracts. Additional information related to each of the revenue streams is further noted below.

Deposit Account Fees

The Company offers various deposit account products to its customers governed by specific deposit agreements applicable to either personal customers or business customers. These agreements identify the general conditions and obligations of both parties, and include standard information regarding deposit account related fees.

Deposit account services include providing access to deposit accounts as well as access to the various deposit transactional services of the Company. These transactional services are primarily those that are identified in the standard fee schedule, and include, but are not limited to, services such as overdraft protection, wire transfer, and check collection. Revenue is recognized in conjunction with the various services being provided. For example, the Company may assess monthly fixed service fees associated with the customer having access to a deposit account, which can vary depending on the account type and daily account balance. In addition, the Company may also assess separate fixed fees associated with and at the time specific transactions are entered into by the customer. As such, the Company considers its performance obligations to be met concurrently with providing the account access or completing the requested deposit transaction.

Cash Management

Cash management services are a subset of the Deposit account fees revenue stream. These services primarily include ACH transaction processing, positive pay and remote deposit services. These services are also governed by separate agreements entered into with the customer. The fee arrangement for these services is structured to assess fees under one of two scenarios, either a per transaction fee arrangement or an earnings credit analysis arrangement. Under the per transaction fee arrangement, fixed fees are assessed concurrently with customers executing the transactions, and as such, the Company considers its performance obligations to be met concurrently with completing the requested transaction. Under the earnings credit analysis arrangement, the Company provides a monthly earnings credit to the customer that is negotiated and determined based on various factors. The credit is then available to absorb the per transaction fees that are assessed on the customer's deposit account activity for the month. Any amount of the transactional fees in excess of the earnings credit is recognized as revenue in that month.

Interchange Fees

The Company earns interchange revenue from its issuance of credit and debit cards granted through its membership in various card payment networks. The Company provides credit cards and debit cards to its customers which are authorized and settled through these payment networks, and in exchange, the Company earns revenue as determined by each payment network's interchange program. The revenue is recognized concurrently with the settlement of card transactions within each network.

ATM Fees

The Company deploys automated teller machines (ATMs) as part of its overall branch network. Certain transactions performed at the ATMs require customers to acknowledge and pay a fee for the requested service. Certain ATM fees are disclosed in the deposit account agreement fee schedules, whereas those assessed to non-Rockland Trust deposit holders are solely determined during the transaction at the machine.

The ATM fee is a fixed dollar per transaction amount, and as such, is recognized concurrently with the overall daily processing and settlement of the ATM activity.

Investment Management - Wealth Management and Advisory Services

The Company offers investment management and trust services to individuals, institutions, small businesses and charitable institutions. Each investment management product is governed by its own contract along with a separate identifiable fee schedule unique to that product. The Company also offers additional services, such as estate settlement, financial planning, tax services and other special services quoted at the client's request.

Asset management and/or custody fees are based upon a percentage of the monthly valuation of the principal assets in the customer's account, whereas fees for additional or special services are fixed in nature and are charged as services are rendered. As the fees are dependent on assets under management, which are susceptible to market factors outside of the Company's control, this variable consideration is constrained and therefore no revenue is estimated at contract initiation. As such, all revenue is recognized in correlation to the monthly management fee determinations or as transactional services are provided. Due to the fact that payments are primarily made subsequent to the valuation period, the Company records a receivable for revenue earned but not received. The following table provides the amount of investment management revenue earned but not received as of the dates indicated:

	March 31, 2023		December 31, 2022
	(Dollars in thousands)
Receivables, included in other assets	$	5,205	$	5,261

Investment Management - Retail Investments and Insurance Revenue

The Company offers the sale of mutual fund shares, unit investment trust shares, third party model portfolios, general securities, fixed and variable annuities and life insurance products through registered representatives who are both employed by the Company and licensed and contracted with various Broker General Agents to offer these products to the Company’s customer base. As such, the Company performs these services as an agent and earns a fixed commission on the sales of these

products and services. To a lesser degree, production bonus commissions can also be earned based upon the Company meeting certain volume thresholds.

In general, the Company recognizes commission revenue at the point of sale, and for certain insurance products, may also earn and recognize annual residual commissions commensurate with annual premiums being paid.

Merchant Processing Income

The Company refers customers to third party merchant processing partners in exchange for commission and fee income. The income earned is comprised of multiple components, including a fixed referral fee per each referred customer, a rebate amount determined primarily as a percentage of net revenue earned by the third party from services provided to each referred customer, and overall production bonus commissions if certain new account production thresholds are met. Merchant processing income is recognized in conjunction with either completing the referral to earn the fixed fee amount or as the merchant activity is processed to derive the Company's rebate and/or production bonus amounts.

Credit Card Income

The Company provides consumer and business credit card solutions to its customers by soliciting new accounts on behalf of a third party credit card provider in exchange for a fee. The income earned is comprised of new account incentive payments as well as a percentage of interchange income earned by the third party provider offering the consumer and business purpose revolving credit accounts. The credit card income is recognized in conjunction with the establishment of each new credit card member or as the interchange is earned by the third party in connection with net purchase transactions made by the credit card member.

Other Noninterest Income

The Company earns various types of other noninterest income that fall within the scope of the new revenue recognition rules, and have been aggregated into one general revenue stream in the table noted above. This amount includes, but is not limited to, the following types of revenue with customers:

Safe Deposit Rent

    The Company rents out the use of safe deposit boxes to its customers, which can be accessed when the bank is open for business. The safe deposit box rental fee is paid upfront and is recognized as revenue ratably over the annual term of the contract.

1031 Exchange Fee Revenue

    The Company provides like-kind exchange services pursuant to Section 1031 of the Internal Revenue Code. Fee income is recognized in conjunction with completing the exchange transactions.

Foreign Currency

    The Company earns fee income associated with various transactions related to foreign currency product offerings, including foreign currency bank notes and drafts and foreign currency wires. The majority of this income is derived from commissions earned related to customers executing the above mentioned foreign currency transactions through arrangements with third party correspondents.

COMMITMENTS AND CONTINGENCIES

Financial Instruments with Off-Balance Sheet Risk

    In the normal course of business, the Company enters into various transactions to meet the financing needs of its customers, which, in accordance with GAAP, are not included in its consolidated balance sheets. These transactions include commitments to extend credit and standby letters of credit, and loan exposures with recourse, which involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. The Company minimizes its exposure to loss under these commitments by subjecting them to credit approval and monitoring procedures.

    The Company enters into contractual commitments to extend credit, normally with fixed expiration dates or termination clauses, at specified rates and for specific purposes. Substantially all of these commitments to extend credit are contingent upon customers maintaining specific credit standards at the time of loan funding.

The Company has certain loan exposures for which there is recourse. These loan relationships could require the Company to repurchase or cover certain losses per agreements for certain loans that are either sold or referred to third parties.

    Standby letters of credit are written conditional commitments issued to guarantee the performance of a customer to a third party. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Company would be required to fund the commitment. The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount of the commitment. If the commitment were funded, the Company would be entitled to seek recovery from the customer. The Company’s policies generally require that standby letter of credit arrangements contain security and debt covenants similar to those contained in loan agreements.

    The fees collected in connection with the issuance of standby letters of credit are representative of the fair value of the Company's obligation undertaken in issuing the guarantee. In accordance with applicable accounting standards related to guarantees, fees collected in connection with the issuance of standby letters of credit are deferred. The fees are then recognized in income proportionately over the life of the standby letter of credit agreement. The deferred standby letter of credit fees represent the fair value of the Company's potential obligations under the standby letter of credit guarantees.

    The following table summarizes the above financial instruments at the dates indicated:

	March 31, 2023		December 31, 2022
	(Dollars in thousands)
Commitments to extend credit	$	4,594,573	$	4,566,041
Loan exposures sold with recourse	164,438		167,274
Standby letters of credit	22,850		24,941
Deferred standby letter of credit fees	190		168

Lease Commitments

The Company leases office and parking space, space for ATM locations, and certain branch locations under noncancellable operating leases. Several of these leases contain renewal options to extend lease terms for a period of 1 to 20 years.

There has been no significant change in the future minimum lease payments payable by the Company since December 31, 2022. See the Company's 2022 Form 10-K for information regarding leases and other commitments.

Other Contingencies

At March 31, 2023, the Bank was involved in pending lawsuits that arose in the ordinary course of business. Management has reviewed these pending lawsuits with legal counsel and has taken into consideration the view of counsel as to their outcome. In the opinion of management, the final disposition of pending lawsuits is not expected to have a material adverse effect on the Company’s financial position or results of operations.

Financing Receivable Credit Quality Indicators For Consumer And Residential Portfolio Table Text Block

The following table shows the weighted average FICO scores and the weighted average combined LTV ratios at the dates indicated below:

	March 31 2023		December 31 2022
Residential real estate portfolio
FICO score (re-scored)(1)	752		753
LTV (re-valued)(2)	58.7	%	57.0	%
Home equity portfolio
FICO score (re-scored)(1)	771		771
LTV (re-valued)(2)(3)	43.8	%	41.3	%

(1)The average FICO scores at March 31, 2023 are based upon rescores from March 2023, as available for previously originated loans, or origination score data for loans booked in March 2023.  The average FICO scores at December 31, 2022 were based upon rescores available from December 2022, as available for previously originated loans, or origination score data for loans booked in December 2022.

(2)The combined LTV ratios for March 31, 2023 are based upon updated automated valuations as of February 2023, when available, and/or the most current valuation data available.  The combined LTV ratios for December 31, 2022 were based upon updated automated valuations as of November 2022, when available, and/or the most current valuation data available as of such date.  The updated automated valuations provide new information on loans that may be available since the previous valuation was obtained.  If no new information is available, the valuation will default to the previously obtained data or most recent appraisal.

(3)For home equity loans and lines in a subordinate lien, the LTV data represents a combined LTV, taking into account the senior lien data for loans and lines.

(a)The fair values presented are based on quoted market prices, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments and/or discounted cash flow analysis.

(b)Fair value of loans is measured using the exit price valuation method, determined primarily by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities or cash flows, while incorporating liquidity and credit assumptions. Additionally, this amount excludes individually assessed collateral dependent loans, which are deemed to be marked to fair value on a nonrecurring basis.

(c)FHLB stock has no quoted market value and is carried at cost; therefore, the carrying amount approximates fair value.

(d)Cash surrender value of life insurance policies is recorded at its cash surrender value (or the amount that can be realized upon surrender of the policy), therefore, carrying amount approximates fair value.

(e)Fair value of demand deposits, savings and interest checking accounts and money market deposits is the amount payable on demand at the reporting date.

(f)Fair value was determined by discounting anticipated future cash payments using rates currently available for instruments with similar remaining maturities.

(g)Fair value was determined based upon market prices of securities with similar terms and maturities.

[1] The carrying value of individually assessed collateral dependent loans is based on the lower of amortized cost or fair value of the underlying collateral less costs to sell. The fair value of the underlying collateral is generally determined through independent appraisals, which generally include various Level 3 inputs which are not identifiable. Appraisals may be adjusted by management for qualitative factors such as economic factors and estimated liquidation expenses. The range of these possible adjustments may vary.

[1] Fair value of demand deposits, savings and interest checking accounts and money market deposits is the amount payable on demand at the reporting date.

[2] Fair value was determined by discounting anticipated future cash payments using rates currently available for instruments with similar remaining maturities.

[3] Fair value was determined based upon market prices of securities with similar terms and maturities.

[4] The fair values presented are based on quoted market prices, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments and/or discounted cash flow analysis.

[5] Fair value of loans is measured using the exit price valuation method, determined primarily by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities or cash flows, while incorporating liquidity and credit assumptions. Additionally, this amount excludes individually assessed collateral dependent loans, which are deemed to be marked to fair value on a nonrecurring basis.

[6] FHLB stock has no quoted market value and is carried at cost; therefore, the carrying amount approximates fair value.

[7] Cash surrender value of life insurance policies is recorded at its cash surrender value (or the amount that can be realized upon surrender of the policy), therefore, carrying amount approximates fair value.
