- Definition

Total of all stockholders' equity (deficit) items, net of receivables from officers, directors, owners, and affiliates of the entity which are attributable to the parent. The amount of the economic entity's stockholders' equity attributable to the parent excludes the amount of stockholders' equity which is allocable to that ownership interest in subsidiary equity which is not attributable to the parent (noncontrolling interest, minority interest). This excludes temporary equity and is sometimes called permanent equity.

Basis of Presentation

The accompanying unaudited interim consolidated financial statements include the accounts of NBT Bancorp Inc. and its wholly-owned subsidiaries: the Bank, NBT Financial and NBT Holdings. Collectively, NBT Bancorp Inc. and its subsidiaries are referred to herein as the “Company”. In the opinion of management, the interim data includes all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and in accordance with the instructions to Quarterly Report on Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission (“SEC”). Accordingly, the consolidated financial statements do not include all of the information and notes necessary for complete financial statements in conformity with GAAP. These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s 2021 Annual Report on Form 10-K. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period. All material intercompany transactions have been eliminated in consolidation. Amounts previously reported in the consolidated financial statements are reclassified whenever necessary to conform to current period presentation. The Company combined ATM and debit card fees with card related income previously reported in Other noninterest income which is now disclosed as Card services income. The Company reclassified Data processing and communications expense into Technology and data services expense. The Company reclassified Equipment expense into Occupancy expense and Technology and data services expense. The Company has evaluated subsequent events for potential recognition and/or disclosure and there were none identified.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results may differ from those estimates and such differences could be material to the financial statements.

Accounting Standards Issued Not Yet Adopted

In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updates (“ASU”) 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. On January 7, 2021, the FASB issued ASU 2021-01, which refines the scope of Accounting Standards Codification 848 (“ASC 848”) and clarifies some of its guidance. ASU 2020-04 and related amendments provide temporary optional expedients and exceptions to the existing guidance for applying GAAP to affected contract modifications and hedge accounting relationships in the transition away from the London Interbank Offered Rate (“LIBOR”) or other interbank offered rate on financial reporting. The guidance also allows a one-time election to sell and/or reclassify to available for sale (“AFS”) or trading held to maturity (“HTM”) debt securities that reference an interest rate affected by reference rate reform. The amendments in this ASU are effective March 12, 2020 through December 31, 2022 and permit relief solely for reference rate reform actions and permit different elections over the effective date for legacy and new activity. The Company does not expect that the impact of adopting the new guidance on the consolidated financial statements will have a material impact on the consolidated financial statements.

In March 2022, the FASB issued ASU 2022-02, Financial Instruments - CECL Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The ASU eliminates the guidance on Troubled Debt Restructurings (“TDRs”) and requires an evaluation on all loan modifications to determine if they result in a new loan or a continuation of the existing loan. The ASU also requires that entities disclose current-period gross charge-offs by year of origination. The elimination of the TDR guidance may be adopted prospectively for loan modifications after adoption or on a modified retrospective basis, which would also apply to loans previously modified, resulting in a cumulative effect adjustment to retained earnings in the period of adoption for changes in the allowance for credit losses. The amendments in this ASU are effective for the Company on January 1, 2023, with early adoption permitted. The Company is evaluating the impact of adopting the new guidance on the consolidated financial statements and does not expect it will have a material impact on the consolidated financial statements.

- Definition

The entire disclosure for change in accounting principle. Includes, but is not limited to, nature, reason, and method of adopting amendment to accounting standards or other change in accounting principle.

At September 30, 2022 and December 31, 2021, all of the mortgaged-backed HTM securities were comprised of U.S. government agency and government-sponsored enterprises securities. There was no allowance for credit losses on HTM securities as of September 30, 2022 and December 31, 2021 because the expectation of nonrepayment of the amortized cost is zero, except for state & municipal securities, which such expected losses from nonrepayment are immaterial.

The Company recorded no gains from calls on HTM securities for the three months ended September 30, 2022. Included in net realized gains (losses), the Company recorded gains from calls on HTM securities of approximately $14 thousand for the three months ended September 30, 2021. Included in net realized gains (losses), the Company recorded gains from calls on HTM securities of approximately $4 thousand and $29 thousand for the nine months ended September 30, 2022 and 2021, respectively.

AFS and HTM securities with amortized costs totaling $1.74 billion at September 30, 2022 and $1.63 billion at December 31, 2021 were pledged to secure public deposits and for other purposes required or permitted by law. Additionally, at September 30, 2022 and December 31, 2021, AFS and HTM securities with an amortized cost of $126.2 million and $162.1 million, respectively, were pledged as collateral for securities sold under repurchase agreements.

As of September 30, 2022 and December 31, 2021, the carrying value of equity securities without readily determinable fair values was $1.0 million. The Company performed a qualitative assessment to determine whether the investments were impaired and identified no areas of concern as of September 30, 2022 and 2021. There were no impairments, downward or upward adjustments recognized for equity securities without readily determinable fair values during the three and nine months ended September 30, 2022 and 2021.

The Company does not believe the AFS securities that were in an unrealized loss position as of September 30, 2022 and December 31, 2021, which consisted of 415 and 149 individual securities, respectively, represented a credit loss impairment. AFS debt securities in unrealized loss positions are evaluated for impairment related to credit losses at least quarterly. As of September 30, 2022 and December 31, 2021, the majority of the AFS securities in an unrealized loss position consisted of debt securities issued by U.S. government agencies or U.S. government-sponsored enterprises that carry the explicit and/or implicit guarantee of the U.S. government, which are widely recognized as “risk free” and have a long history of zero credit losses. Total gross unrealized losses were primarily attributable to changes in interest rates, relative to when the investment securities were purchased, and not due to the credit quality of the investment securities. The Company does not intend to sell, nor is it more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis, which may be at maturity. The Company elected to exclude accrued interest receivable (“AIR”) from the amortized cost basis of debt securities. AIR on AFS debt securities totaled $4.3 million at September 30, 2022 and $3.9 million at December 31, 2021 and is excluded from the estimate of credit losses and reported in the financial statement line for other assets.

None of the Bank’s HTM debt securities were past due or on nonaccrual status as of September 30, 2022 and December 31, 2021. There was no accrued interest reversed against interest income for the three and nine months ended September 30, 2022 or the year ended December 31, 2021 as all securities remained on accrual status. In addition, there were no collateral-dependent HTM debt securities as of September 30, 2022 and December 31, 2021. As of September 30, 2022 and December 31, 2021, 69% and 56%, respectively, of the Company’s HTM debt securities were issued by U.S. government agencies or U.S. government-sponsored enterprises. These securities carry the explicit and/or implicit guarantee of the U.S. government, are widely recognized as “risk free,” and have a long history of zero credit losses. Therefore, the Company did not record an allowance for credit losses for these securities as of September 30, 2022 and December 31, 2021. The remaining HTM debt securities at September 30, 2022 and December 31, 2021 were comprised of state and municipal obligations with bond ratings of A to AAA. Utilizing the Current Expected Credit Losses (“CECL”) approach, the Company determined that the expected credit loss on its HTM municipal bond portfolio was immaterial and therefore no allowance for credit loss was recorded as of September 30, 2022 and December 31, 2021. AIR on HTM debt securities totaled $3.3 million at September 30, 2022 and $2.7 million at December 31, 2021 and is excluded from the estimate of credit losses and reported in the other assets financial statement line.

Allowance for Credit Losses and Credit Quality of Loans [Abstract]

Allowance for Credit Losses and Credit Quality of Loans

5.	Allowance for Credit Losses and Credit Quality of Loans

The allowance for credit losses totaled $96.8 million at September 30, 2022, compared to $92.0 million at December 31, 2021. The allowance for credit losses as a percentage of loans was 1.22% at September 30, 2022, compared to 1.23% at December 31, 2021.

The allowance for credit losses calculation incorporated a 6-quarter forecast period to account for forecast economic conditions under each scenario utilized in the measurement. For periods beyond the 6-quarter forecast, the model reverts to long-term economic conditions over a 4-quarter reversion period on a straight-line basis. The Company considers a baseline, upside and downside economic forecast in measuring the allowance.

The quantitative model as of September 30, 2022 incorporated a baseline economic outlook along with an alternative downside scenario sourced from a reputable third-party to accommodate other potential economic conditions in the model, particularly significant unknowns relating to downside risks as of the measurement date. The baseline outlook reflected an unemployment rate environment at pre-coronavirus (“COVID-19”) pandemic levels of 3.8% and maintaining those levels to the end of the forecast period. Northeast GDP’s annualized growth (on a quarterly basis) is expected to start the fourth quarter of 2022 at about 4.5% and hover around that level across the forecast period. Other utilized economic variables worsened overall during the fourth quarter of the forecast, with outlooks for annualized growth in retail sales and business output declining from the prior quarter along with housing starts. Key assumptions in the baseline economic outlook included the economy reaching full employment in the coming quarters, further interest rate increases by the Federal Reserve, and the global oil market remaining relatively balanced into 2023. The alternative downside scenario assumed deteriorated economic conditions from the baseline outlook. Under this scenario, northeast unemployment rises from 4.0% in the third quarter of 2022 to a peak of 6.9% in the fourth quarter of 2023. The alternative upside scenario incorporated a more optimistic outlook than the baseline scenario, with an imminent return to full employment and northeast unemployment declining to 3.3% by the end of the forecast period. These scenarios and their respective weightings are evaluated at each measurement date and reflect management’s expectations as of September 30, 2022. At September 30, 2022, the weightings were 50%, 0% and 50% for the baseline, upside and downside economic forecasts, respectively. Qualitative adjustments were made for isolated model limitations related to modeled inputs and outputs given abnormally high retail sales and business output growth rates in prior quarters. Additionally, a qualitative adjustment for inflation was added to adjust for potential model limitations arising from the use of a macroeconomic variable denominated in nominal dollar terms. These factors were considered through separate quantitative processes and incorporated into the estimate of current expected credit losses at September 30, 2022.

The quantitative model as of June 30, 2022 incorporated a baseline economic outlook along with an alternative downside scenario sourced from a reputable third-party to accommodate other potential economic conditions in the model, particularly significant unknowns relating to downside risks as of the measurement date. The baseline outlook reflected an unemployment rate environment initially at pre-COVID-19 levels of 3.8% but falling below pre-COVID-19 levels by the end of the forecast period to a low of 3.4%. Northeast GDP’s annualized growth (on a quarterly basis) is expected to start the third quarter of 2022 at about 9.5% and hover around 5% by the end of the forecast period. Other utilized economic variables worsened overall during the quarter, with outlooks for annualized growth in retail sales and business output declining from the prior quarter along with housing starts. Key assumptions in the baseline economic outlook included the containment of the European conflict to only Russia and Ukraine, further interest rate increases by the Federal Reserve, and achievement of full employment by the end of 2022. The alternative downside scenario assumed deteriorated economic and pandemic related conditions from the baseline outlook. Under this scenario, northeast unemployment rises from 4.2% in the second quarter of 2022 to a peak of 7.0% in the third quarter of 2023. The alternative upside scenario incorporated a more optimistic outlook than the baseline scenario, with an imminent return to full employment, with northeast unemployment declining to 2.9% by the end of the forecast period. These scenarios and their respective weightings are evaluated at each measurement date and reflect management’s expectations as of June 30, 2022. At June 30, 2022, the weightings were 50%, 0% and 50% for the baseline, upside and downside economic forecasts, respectively. Additionally, qualitative adjustments were made for isolated model limitations related to modeled outputs given abnormally high retail sales and business output growth rates in prior quarters. These factors were considered through separate quantitative processes and incorporated into the estimate of current expected credit losses at June 30, 2022.

The quantitative model as of December 31, 2021 incorporated a baseline economic outlook along with alternative upside and downside scenarios sourced from a reputable third-party to accommodate other potential economic conditions in the model. The baseline outlook reflected an unemployment rate environment initially above pre-COVID-19 levels at 4.8% but falling below pre-COVID-19 levels by the end of the forecast period to 3.5%. Northeast GDP’s annualized growth (on a quarterly basis) was expected to start the first quarter of 2022 at approximately 9% and hover around 5% by the middle and end of the forecast period. The alternative downside scenario assumed deteriorated economic and pandemic related conditions from the baseline outlook. Under this scenario, northeast unemployment rose from 5.7% in the fourth quarter of 2021 to a peak of 8% in the first quarter of 2023, remaining around or above 7% for the entire forecast period. The alternative upside scenario incorporated a more optimistic outlook than the baseline scenario, with a swift return to full employment by the second quarter of 2022 and with northeast unemployment moving down to 3.1% by the end of the forecast period. These scenarios and their respective weightings are evaluated at each measurement date and reflect management’s expectations as of December 31, 2021. At December 31, 2021, the weightings were 60%, 10% and 30% for the baseline, upside and downside economic forecasts, respectively. Additional adjustments were made for COVID-19 related factors not incorporated in the forecasts, such as the mitigating impact of unprecedented stimulus in the second and third quarters of 2020, including direct payments to individuals, increased unemployment benefits, the Company’s loan deferral and modification initiatives and various government sponsored loan programs. The Company also continued to monitor the level of criticized and classified loans in the fourth quarter of 2021 compared to the level contemplated by the model during similar, historical economic conditions, and an adjustment was made to estimate potential additional losses above modeled losses. Additionally, qualitative adjustments were made for Moody’s baseline economic forecast to include impacts of the Build Back Better Act not passing by December 31, 2021 and to address potential economic deterioration due to Omicron, as well as isolated model limitations related to modeled outputs given abnormally high retail sales and business output growth rates in historical periods. These factors were considered through separate quantitative processes and incorporated into the estimate of current expected credit losses at December 31, 2021.

There were no loans purchased with credit deterioration during the nine months ended September 30, 2022 or the year ended December 31, 2021. During 2022, the Company purchased $8.0 million of residential loans at a slight discount and $50.1 million in consumer loans at par. The allowance for credit losses recorded for these loans on the purchase date was $3.2 million. During 2021, the Company purchased $58.9 million of residential loans at a 2%-5% premium and $92.5 million in consumer loans at par. The allowance for credit losses recorded for these loans on the purchase date was $6.8 million. The Company made a policy election to report AIR in the other assets line item on the balance sheet. AIR on loans totaled $21.2 million at September 30, 2022 and $19.5 million at December 31, 2021 and there was no estimated allowance for credit losses related to AIR as of September 30, 2022 and December 31, 2021.

The increase in the allowance for credit losses from December 31, 2021 and June 30, 2022 to September 30, 2022 was due to an increase in loan balances and a modest deterioration in the economic forecast. The decrease in the allowance for credit losses from December 31, 2020 and June 30, 2021 to September 30, 2021 was primarily due to an improvement in the economic forecast.

Individually Evaluated Loans

As of September 30, 2022, there were four relationships identified to be evaluated for loss on an individual basis which, in aggregate, had an amortized cost basis of $4.3 million, with no allowance for credit loss. As of December 31, 2021, there were five relationships identified to be evaluated for loss on an individual basis with an aggregate amortized cost basis of $10.2 million and no allowance for credit loss. The decrease in the amortized cost basis on an individual basis from December 31, 2021 to September 30, 2022 was primarily due to principal payments and resolution of one relationship in which the cost basis was substantially collected and the related $0.8 million allowance for credit losses was reversed.

Credit Quality Indicators

The Company has developed an internal loan grading system to evaluate and quantify the Company’s loan portfolio with respect to quality and risk. The system focuses on, among other things, financial strength of borrowers, experience and depth of borrower’s management, primary and secondary sources of repayment, payment history, nature of the business and outlook on particular industries. The internal grading system enables the Company to monitor the quality of the entire loan portfolio on a consistent basis and provide management with an early warning system, which facilitates recognition and response to problem loans and potential problem loans.

Commercial Grading System

For Commercial and Industrial (“C&I”), Paycheck Protection Program (“PPP”) and Commercial Real Estate (“CRE”) loans, the Company uses a grading system that relies on quantifiable and measurable characteristics when available. This includes comparison of financial strength to available industry averages, comparison of transaction factors (loan terms and conditions) to loan policy and comparison of credit history to stated repayment terms and industry averages. Some grading factors are necessarily more subjective such as economic and industry factors, regulatory environment and management. C&I and CRE loans are graded Doubtful, Substandard, Special Mention and Pass.

Doubtful

A Doubtful loan has a high probability of total or substantial loss, but because of specific pending events that may strengthen the asset, its classification as a loss is deferred. Doubtful borrowers are usually in default, lack adequate liquidity or capital and lack the resources necessary to remain an operating entity. Pending events can include mergers, acquisitions, liquidations, capital injections, the perfection of liens on additional collateral, the valuation of collateral and refinancing. Generally, pending events should be resolved within a relatively short period and the ratings will be adjusted based on the new information. Nonaccrual treatment is required for Doubtful assets because of the high probability of loss.

Substandard

Substandard loans have a high probability of payment default or they have other well-defined weaknesses. They require more intensive supervision by bank management. Substandard loans are generally characterized by current or expected unprofitable operations, inadequate debt service coverage, inadequate liquidity and/or marginal capitalization. Repayment may depend on collateral or other credit risk mitigants. For some Substandard loans, the likelihood of full collection of interest and principal may be in doubt and those loans should be placed on nonaccrual. Although Substandard assets, in the aggregate, will have a distinct potential for loss, an individual asset’s loss potential does not have to be distinct for the asset to be rated Substandard.

Special Mention

Special Mention loans have potential weaknesses that may, if not checked or corrected, weaken the asset or inadequately protect the Company’s position at some future date. These loans pose elevated risk, but their weakness does not yet justify a Substandard classification. Borrowers may be experiencing adverse operating trends (e.g., declining revenues or margins) or may be struggling with an ill-proportioned balance sheet (e.g., increasing inventory without an increase in sales, high leverage, and/or tight liquidity). Adverse economic or market conditions, such as interest rate increases or the entry of a new competitor, may also support a Special Mention rating. Although a Special Mention loan has a higher probability of default than a Pass asset, its default is not imminent.

Pass

Loans graded as Pass encompass all loans not graded as Doubtful, Substandard or Special Mention. Pass loans are in compliance with loan covenants and payments are generally made as agreed. Pass loans range from superior quality to fair quality. Pass loans also include any portion of a government guaranteed loan, including PPP loans.

Consumer and Residential Grading System

Consumer and Residential loans are graded as either Nonperforming or Performing.

Nonperforming

Nonperforming loans are loans that are (1) over 90 days past due and interest is still accruing or (2) on nonaccrual status.

Performing

All loans not meeting any of the above criteria are considered Performing.

Allowance for Credit Losses on Off-Balance Sheet Credit Exposures

The allowance for losses on unfunded commitments totaled $5.3 million as of September 30, 2022, compared to $5.1 million as of December 31, 2021.

Troubled Debt Restructuring

When the Company modifies a loan in a TDR, such modifications generally include one or a combination of the following: an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk; a temporary reduction in the interest rate; or a change in scheduled payment amount. Residential and Consumer TDRs occurring during 2022 and 2021 were due to reductions in the interest rate and/or extensions of the term.

An allowance for impaired commercial and consumer loans that have been modified in a TDR is measured based on the present value of the expected future cash flows, discounted at the contractual interest rate of the original loan agreement, except when the sole (remaining) source of repayment for the loan is the operation or liquidation of the collateral. In these cases, management uses the current fair value of the collateral, less selling costs. If management determines that the value of the modified loan is less than the recorded investment in the loan, an impairment charge would be recorded.

The Company began offering loan modifications to assist borrowers during the COVID-19 national emergency. The Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”), along with a joint agency statement issued by banking regulatory agencies, provides that modifications made in response to COVID-19 do not need to be accounted for as a TDR. The Company evaluated the modification programs provided to its borrowers and concluded the modifications were generally made in accordance with the CARES Act guidance to borrowers who were in good standing prior to the COVID-19 pandemic and are not required to be designated as TDRs.

The following tables illustrate the recorded investment and number of modifications designated as TDRs, including the recorded investment in the loans prior to a modification and the recorded investment in the loans after restructuring:

Defined Benefit Post-Retirement Plans [Abstract]

Defined Benefit Post-Retirement Plans

6.	Defined Benefit Post-Retirement Plans

The Company has a qualified, noncontributory, defined benefit pension plan (the “Plan”) covering substantially all of its employees at September 30, 2022. Benefits paid from the Plan are based on age, years of service, compensation and social security benefits and are determined in accordance with defined formulas. The Company’s policy is to fund the Plan in accordance with Employee Retirement Income Security Act of 1974 standards. Assets of the Plan are invested in publicly traded stocks and mutual funds. In addition to the Plan, the Company provides supplemental employee retirement plans to certain current and former executives. The Company also assumed supplemental retirement plans for former executives of Alliance Financial Corporation (“Alliance”) when the Company acquired Alliance. These supplemental employee retirement plans and the Plan are collectively referred to herein as “Pension Benefits”.

In addition, the Company provides certain health care benefits for retired employees. Benefits were accrued over the employees’ active service period. Only employees that were employed by the Company on or before January 1, 2000 are eligible to receive post-retirement health care benefits. In addition, the Company assumed post-retirement medical and life insurance benefits for certain Alliance employees, retirees and their spouses, if applicable, in the Alliance acquisition. These post-retirement benefits are referred to herein as “Other Benefits”.

The Company made no voluntary contributions to the pension and other benefits plans during the three and nine months ended September 30, 2022 and 2021.

The components of expense for Pension Benefits and Other Benefits are set forth below:

	Pension Benefits						Other Benefits

Earnings Per Share [Abstract]

Earnings Per Share

7.	Earnings Per Share

Basic earnings per share (“EPS”) excludes dilution and is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity (such as the Company’s dilutive stock options and restricted stock units).

The following is a reconciliation of basic and diluted EPS for the periods presented in the unaudited interim consolidated statements of income:

	Three Months Ended September 30,
(In thousands, except per share data)	2022		2021
Basic EPS:
Weighted average common shares outstanding		42,838		43,360
Net income available to common stockholders	$	38,973	$	37,433
Basic EPS	$	0.91	$	0.86

Diluted EPS:
Weighted average common shares outstanding		42,838		43,360
Dilutive effect of common stock options and restricted stock		273		271
Weighted average common shares and common share equivalents		43,111		43,631
Net income available to common stockholders	$	38,973	$	37,433
Diluted EPS	$	0.90	$	0.86

	Nine Months Ended September 30,
(In thousands, except per share data)	2022		2021
Basic EPS:
Weighted average common shares outstanding		42,940		43,464
Net income available to common stockholders	$	115,874	$	117,575
Basic EPS	$	2.70	$	2.71

Diluted EPS:
Weighted average common shares outstanding		42,940		43,464
Dilutive effect of common stock options and restricted stock		254		305
Weighted average common shares and common share equivalents		43,194		43,769
Net income available to common stockholders	$	115,874	$	117,575
Diluted EPS	$	2.68	$	2.69

There was a nominal number of weighted average stock options outstanding for the three and nine months ended September 30, 2022 and September 30, 2021, that were not considered in the calculation of diluted EPS since the stock options’ exercise prices were greater than the average market price during these periods.

Derivative Instruments and Hedging Activities [Abstract]

Derivative Instruments and Hedging Activities

9.	Derivative Instruments and Hedging Activities

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate risk, primarily by managing the amount, sources and duration of its assets and liabilities and through the use of derivative instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. Generally, the Company may use derivative financial instruments 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. Currently, the Company has interest rate derivatives that result from a service provided to certain qualifying customers and, therefore, are not used to manage interest rate risk in the Company’s assets or liabilities. The Company manages a matched book with respect to its derivative instruments in order to minimize its net risk exposure resulting from such transactions.

Derivatives Not Designated as Hedging Instruments

The Company enters into interest rate swaps to facilitate customer transactions and meet their financing needs. These swaps are considered derivatives, but are not designated as hedging relationships. These instruments have interest rate and credit risk associated with them. To mitigate the interest rate risk, the Company enters into offsetting interest rate swaps with counterparties. The counterparty swaps are also considered derivatives and are also not designated in hedging relationships. Interest rate swaps are recorded within other assets or other liabilities on the consolidated balance sheet at their estimated fair value. Changes to the fair value of assets and liabilities arising from these derivatives are included, net, in other operating income in the consolidated statement of income.

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 began to clear certain derivative transactions through the Chicago Mercantile Exchange Clearing House (“CME”) in January 2021. The CME requires the Company to post initial and variation margin payments 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. 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.

As of September 30, 2022 and December 31, 2021, the Company had fifteen and eighteen risk participation agreements, respectively, with financial institution counterparties for interest rate swaps related to participated loans. Risk participation agreements provide credit protection to the financial institution that originated the swap transaction should the borrower fail to perform on its obligation. The Company enters into both risk participation agreements in which it purchases credit protection from other financial institutions and those in which it provides credit protection to other financial institutions.

Derivatives Designated as Hedging Instruments

The Company has previously entered into interest rate swaps to modify the interest rate characteristics of certain short-term Federal Home Loan Bank (“FHLB”) advances from variable rate to fixed rate in order to reduce the impact of changes in future cash flows due to market interest rate changes. These agreements are designated as cash flow hedges with currently none outstanding.

The following table summarizes the derivatives outstanding:

(In thousands)	Notional Amount		Balance Sheet Location	Fair Value		Notional Amount		Balance Sheet Location	Fair Value
As of September 30, 2022
Derivatives not designated as hedging instruments
Interest rate derivatives	$	1,380,347	Other assets	$	124,892	$	1,380,347	Other liabilities	$	124,892

Derivatives not offset on the balance sheet				$	5,455					$	5,455
Cash collateral⁽²⁾					-						43,420
Net derivative amounts				$	55,170					$	5,906

(1)

Netting adjustments represents the amounts recorded to convert derivatives assets and liabilities from a gross basis to a net basis in accordance with the applicable accounting guidance on the settle-to-market rules for cleared derivatives. The CME legally characterizes the variation margin posted between counterparties as settlements of the outstanding derivative contracts instead of cash collateral. The Company began to clear certain derivative transactions through the CME in 2021.

(2)

Cash collateral represents the amount that cannot be used to offset our derivative assets and liabilities from a gross basis to a net basis in accordance with the applicable accounting guidance. The other collateral consists of securities and is exchanged under bilateral collateral and master netting agreements that allow us to offset the net derivative position with the related collateral. The application of the other collateral cannot reduce the net derivative position below zero. Therefore, excess other collateral, if any, is not reflected above.

For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in AOCI and subsequently reclassified into interest expense in the same period during which the hedge transaction affects earnings. Amounts reported in AOCI related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s short-term rate borrowings. During the three months ended March 31, 2021 the Company’s final cash flow hedge of interest rate risk matured and the remaining balance was reclassified from AOCI as a reduction to interest expense. There is no additional amount that will be reclassified from AOCI as a reduction to interest expense.

The following table indicates the effect of cash flow hedge accounting on AOCI and on the unaudited interim consolidated statement of income:

Fair Value Measurements and Fair Value of Financial Instruments

Fair Value Measurements and Fair Value of Financial Instruments [Abstract]

Fair Value Measurements and Fair Value of Financial Instruments

10.	Fair Value Measurements and Fair Value of Financial Instruments

GAAP states that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value measurements are not adjusted for transaction costs. A fair value hierarchy exists within GAAP 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 are described below:

Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2 - Quoted prices for similar assets or liabilities in active markets, quoted prices in markets that are not active or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and

Level 3 - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (e.g., supported by little or no market activity).

A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.

The types of instruments valued based on quoted market prices in active markets include most U.S. government and agency securities, many other sovereign government obligations, liquid mortgage products, active listed equities and most money market securities. Such instruments are generally classified within Level 1 or Level 2 of the fair value hierarchy. The Company does not adjust the quoted prices for such instruments.

The types of instruments valued based on quoted prices in markets that are not active, broker or dealer quotations or quote from alternative pricing sources with reasonable levels of price transparency include most investment-grade and high-yield corporate bonds, less liquid mortgage products, less liquid agency securities, less liquid listed equities, state, municipal and provincial obligations and certain physical commodities. Such instruments are generally classified within Level 2 of the fair value hierarchy. Certain common equity securities are reported at fair value utilizing Level 1 inputs (exchange quoted prices). Other investment securities are reported at fair value utilizing Level 1 and Level 2 inputs. The prices for Level 2 instruments are obtained through an independent pricing service or dealer market participants with whom the Company has historically transacted both purchases and sales of investment securities. Prices obtained from these sources include prices derived from market quotations and matrix pricing. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. Management reviews the methodologies used by its third-party providers in pricing the securities.

Level 3 is for positions that are not traded in active markets or are subject to transfer restrictions. Valuations are adjusted to reflect illiquidity and/or non-transferability and such adjustments are generally based on available market evidence. In the absence of such evidence, management’s best estimate will be used. Management’s best estimate consists of both internal and external support on certain Level 3 investments. Subsequent to inception, management only changes Level 3 inputs and assumptions when corroborated by evidence such as transactions in similar instruments, completed or pending third-party transactions in the underlying investment or comparable entities, subsequent rounds of financing, recapitalizations and other transactions across the capital structure, offerings in the equity or debt markets and changes in financial ratios or cash flows.

The following tables set forth the Company’s financial assets and liabilities measured on a recurring basis that were accounted for at fair value. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement:

GAAP requires disclosure of assets and liabilities measured and recorded at fair value on a non-recurring basis such as goodwill, loans held for sale, other real estate owned, collateral-dependent impaired loans and HTM securities. The non-recurring fair value measurements recorded during the three and nine month periods ended September 30, 2022 and the year ended December 31, 2021 were related to impaired loans, write-downs of other real estate owned and write-down of branch assets to fair value. The Company uses the fair value of underlying collateral, less costs to sell, to estimate the allowance for credit losses for individually evaluated collateral dependent loans. The appraisals may be adjusted by management for qualitative factors such as economic conditions and estimated liquidation expenses ranging from 10% to 50%. Based on the valuation techniques used, the fair value measurements for collateral dependent individually evaluated loans are classified as Level 3.

The following table sets forth information with regard to estimated fair values of financial instruments. This table excludes financial instruments for which the carrying amount approximates fair value. Financial instruments for which the fair value approximates carrying value include cash and cash equivalents, AFS securities, equity securities, accrued interest receivable, non-maturity deposits, short-term borrowings, accrued interest payable and derivatives.

			September 30, 2022				December 31, 2021
(In thousands)	Fair Value Hierarchy		Carrying Amount		Estimated Fair Value		Carrying Amount		Estimated Fair Value

HTM securities		2	$	929,541	$	814,100	$	733,210	$	735,260
Net loans		3		7,808,071		7,538,178		7,407,289		7,530,768
Financial liabilities:

Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Fair value estimates are based on existing on and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. For example, the Company has a substantial wealth operation that contributes net fee income annually. The wealth management operation is not considered a financial instrument and its value has not been incorporated into the fair value estimates. Other significant assets and liabilities include the benefits resulting from the low-cost funding of deposit liabilities as compared to the cost of borrowing funds in the market and premises and equipment. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimate of fair value.

HTM Securities

The fair value of the Company’s HTM securities is primarily measured using information from a third-party pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things.

Net Loans

Net loans include portfolio loans and loans held for sale. Loans were first segregated by type and then further segmented into fixed and variable rate and loan quality categories. Expected future cash flows were projected based on contractual cash flows, adjusted for estimated prepayments, including credit risk, illiquidity risk and other market factors to calculate the exit price fair value in accordance with ASC 820.

Time Deposits

The fair value of time deposits was estimated using a discounted cash flow approach that applies prevailing market interest rates for similar maturity instruments. The fair values of the Company’s time deposit liabilities do not take into consideration the value of the Company’s long-term relationships with depositors, which may have significant value.

Long-Term Debt

The fair value of long-term debt was estimated using a discounted cash flow approach that applies prevailing market interest rates for similar maturity instruments.

Subordinated Debt

The fair value of subordinated debt has been measured using the observable market price as of the period reported.

Junior Subordinated Debt

The fair value of junior subordinated debt has been estimated using a discounted cash flow analysis.

Commitments and Contingencies [Abstract]

Commitments and Contingencies

11.	Commitments and Contingencies

The Company is a party to certain financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, unused lines of credit, standby letters of credit and certain agricultural real estate loans sold to investors with recourse, with the sold portion having a government guarantee that is assignable back to the Company upon repurchase of the loan in the event of default. The Company’s exposure to credit loss in the event of nonperformance by the other party to the commitments to extend credit, unused lines of credit, standby letters of credit and loans sold with recourse is represented by the contractual amount of those investments. The credit risk associated with commitments to extend credit and standby and commercial letters of credit is essentially the same as that involved with extending loans to customers and is subject to normal credit policies. Collateral may be obtained based on management’s assessment of the customer’s credit worthiness. Commitments to extend credit and unused lines of credit totaled $2.40 billion at September 30, 2022 and $2.30 billion at December 31, 2021.

Since many loan commitments, standby letters of credit and guarantees and indemnification contracts expire without being funded in whole or in part, the contract amounts are not necessarily indicative of future cash flows. The Company does not issue any guarantees that would require liability-recognition or disclosure, other than its standby letters of credit.

The Company guarantees the obligations or performance of customers by issuing standby letters of credit to third-parties. These standby letters of credit are generally issued in support of third-party debt, such as corporate debt issuances, industrial revenue bonds and municipal securities. The risk involved in issuing standby letters of credit is essentially the same as the credit risk involved in extending loan facilities to customers and letters of credit are subject to the same credit origination, portfolio maintenance and management procedures in effect to monitor other credit and off-balance sheet products. Typically, these instruments have one year expirations with an option to renew upon annual review; therefore, the total amounts do not necessarily represent future cash requirements. Standby letters of credit totaled $54.3 million at September 30, 2022 and $55.1 million at December 31, 2021. As of September 30, 2022 and December 31, 2021, the fair value of the Company’s standby letters of credit was not significant.

Recent Accounting Pronouncements [Abstract]
Accounting Standards Issued Not Yet Adopted	Accounting Standards Issued Not Yet Adopted In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updates (“ASU”) 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. On January 7, 2021, the FASB issued ASU 2021-01, which refines the scope of Accounting Standards Codification 848 (“ASC 848”) and clarifies some of its guidance. ASU 2020-04 and related amendments provide temporary optional expedients and exceptions to the existing guidance for applying GAAP to affected contract modifications and hedge accounting relationships in the transition away from the London Interbank Offered Rate (“LIBOR”) or other interbank offered rate on financial reporting. The guidance also allows a one-time election to sell and/or reclassify to available for sale (“AFS”) or trading held to maturity (“HTM”) debt securities that reference an interest rate affected by reference rate reform. The amendments in this ASU are effective March 12, 2020 through December 31, 2022 and permit relief solely for reference rate reform actions and permit different elections over the effective date for legacy and new activity. The Company does not expect that the impact of adopting the new guidance on the consolidated financial statements will have a material impact on the consolidated financial statements. In March 2022, the FASB issued ASU 2022-02, Financial Instruments - CECL Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The ASU eliminates the guidance on Troubled Debt Restructurings (“TDRs”) and requires an evaluation on all loan modifications to determine if they result in a new loan or a continuation of the existing loan. The ASU also requires that entities disclose current-period gross charge-offs by year of origination. The elimination of the TDR guidance may be adopted prospectively for loan modifications after adoption or on a modified retrospective basis, which would also apply to loans previously modified, resulting in a cumulative effect adjustment to retained earnings in the period of adoption for changes in the allowance for credit losses. The amendments in this ASU are effective for the Company on January 1, 2023, with early adoption permitted. The Company is evaluating the impact of adopting the new guidance on the consolidated financial statements and does not expect it will have a material impact on the consolidated financial statements.

Securities (Policies)	Sep. 30, 2022
Securities [Abstract]
Investment, Policy	The Company does not believe the AFS securities that were in an unrealized loss position as of September 30, 2022 and December 31, 2021, which consisted of 415 and 149 individual securities, respectively, represented a credit loss impairment. AFS debt securities in unrealized loss positions are evaluated for impairment related to credit losses at least quarterly. As of September 30, 2022 and December 31, 2021, the majority of the AFS securities in an unrealized loss position consisted of debt securities issued by U.S. government agencies or U.S. government-sponsored enterprises that carry the explicit and/or implicit guarantee of the U.S. government, which are widely recognized as “risk free” and have a long history of zero credit losses. Total gross unrealized losses were primarily attributable to changes in interest rates, relative to when the investment securities were purchased, and not due to the credit quality of the investment securities. The Company does not intend to sell, nor is it more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis, which may be at maturity. The Company elected to exclude accrued interest receivable (“AIR”) from the amortized cost basis of debt securities. AIR on AFS debt securities totaled $4.3 million at September 30, 2022 and $3.9 million at December 31, 2021 and is excluded from the estimate of credit losses and reported in the financial statement line for other assets. None of the Bank’s HTM debt securities were past due or on nonaccrual status as of September 30, 2022 and December 31, 2021. There was no accrued interest reversed against interest income for the three and nine months ended September 30, 2022 or the year ended December 31, 2021 as all securities remained on accrual status. In addition, there were no collateral-dependent HTM debt securities as of September 30, 2022 and December 31, 2021. As of September 30, 2022 and December 31, 2021, 69% and 56%, respectively, of the Company’s HTM debt securities were issued by U.S. government agencies or U.S. government-sponsored enterprises. These securities carry the explicit and/or implicit guarantee of the U.S. government, are widely recognized as “risk free,” and have a long history of zero credit losses. Therefore, the Company did not record an allowance for credit losses for these securities as of September 30, 2022 and December 31, 2021. The remaining HTM debt securities at September 30, 2022 and December 31, 2021 were comprised of state and municipal obligations with bond ratings of A to AAA. Utilizing the Current Expected Credit Losses (“CECL”) approach, the Company determined that the expected credit loss on its HTM municipal bond portfolio was immaterial and therefore no allowance for credit loss was recorded as of September 30, 2022 and December 31, 2021. AIR on HTM debt securities totaled $3.3 million at September 30, 2022 and $2.7 million at December 31, 2021 and is excluded from the estimate of credit losses and reported in the other assets financial statement line.

Allowance for Credit Losses and Credit Quality of Loans (Policies)	9 Months Ended

Allowance for Credit Losses and Credit Quality of Loans [Abstract]
Allowance for Credit Losses	The allowance for credit losses calculation incorporated a 6-quarter forecast period to account for forecast economic conditions under each scenario utilized in the measurement. For periods beyond the 6-quarter forecast, the model reverts to long-term economic conditions over a 4-quarter reversion period on a straight-line basis. The Company considers a baseline, upside and downside economic forecast in measuring the allowance. The quantitative model as of September 30, 2022 incorporated a baseline economic outlook along with an alternative downside scenario sourced from a reputable third-party to accommodate other potential economic conditions in the model, particularly significant unknowns relating to downside risks as of the measurement date. The baseline outlook reflected an unemployment rate environment at pre-coronavirus (“COVID-19”) pandemic levels of 3.8% and maintaining those levels to the end of the forecast period. Northeast GDP’s annualized growth (on a quarterly basis) is expected to start the fourth quarter of 2022 at about 4.5% and hover around that level across the forecast period. Other utilized economic variables worsened overall during the fourth quarter of the forecast, with outlooks for annualized growth in retail sales and business output declining from the prior quarter along with housing starts. Key assumptions in the baseline economic outlook included the economy reaching full employment in the coming quarters, further interest rate increases by the Federal Reserve, and the global oil market remaining relatively balanced into 2023. The alternative downside scenario assumed deteriorated economic conditions from the baseline outlook. Under this scenario, northeast unemployment rises from 4.0% in the third quarter of 2022 to a peak of 6.9% in the fourth quarter of 2023. The alternative upside scenario incorporated a more optimistic outlook than the baseline scenario, with an imminent return to full employment and northeast unemployment declining to 3.3% by the end of the forecast period. These scenarios and their respective weightings are evaluated at each measurement date and reflect management’s expectations as of September 30, 2022. At September 30, 2022, the weightings were 50%, 0% and 50% for the baseline, upside and downside economic forecasts, respectively. Qualitative adjustments were made for isolated model limitations related to modeled inputs and outputs given abnormally high retail sales and business output growth rates in prior quarters. Additionally, a qualitative adjustment for inflation was added to adjust for potential model limitations arising from the use of a macroeconomic variable denominated in nominal dollar terms. These factors were considered through separate quantitative processes and incorporated into the estimate of current expected credit losses at September 30, 2022. The quantitative model as of June 30, 2022 incorporated a baseline economic outlook along with an alternative downside scenario sourced from a reputable third-party to accommodate other potential economic conditions in the model, particularly significant unknowns relating to downside risks as of the measurement date. The baseline outlook reflected an unemployment rate environment initially at pre-COVID-19 levels of 3.8% but falling below pre-COVID-19 levels by the end of the forecast period to a low of 3.4%. Northeast GDP’s annualized growth (on a quarterly basis) is expected to start the third quarter of 2022 at about 9.5% and hover around 5% by the end of the forecast period. Other utilized economic variables worsened overall during the quarter, with outlooks for annualized growth in retail sales and business output declining from the prior quarter along with housing starts. Key assumptions in the baseline economic outlook included the containment of the European conflict to only Russia and Ukraine, further interest rate increases by the Federal Reserve, and achievement of full employment by the end of 2022. The alternative downside scenario assumed deteriorated economic and pandemic related conditions from the baseline outlook. Under this scenario, northeast unemployment rises from 4.2% in the second quarter of 2022 to a peak of 7.0% in the third quarter of 2023. The alternative upside scenario incorporated a more optimistic outlook than the baseline scenario, with an imminent return to full employment, with northeast unemployment declining to 2.9% by the end of the forecast period. These scenarios and their respective weightings are evaluated at each measurement date and reflect management’s expectations as of June 30, 2022. At June 30, 2022, the weightings were 50%, 0% and 50% for the baseline, upside and downside economic forecasts, respectively. Additionally, qualitative adjustments were made for isolated model limitations related to modeled outputs given abnormally high retail sales and business output growth rates in prior quarters. These factors were considered through separate quantitative processes and incorporated into the estimate of current expected credit losses at June 30, 2022. The quantitative model as of December 31, 2021 incorporated a baseline economic outlook along with alternative upside and downside scenarios sourced from a reputable third-party to accommodate other potential economic conditions in the model. The baseline outlook reflected an unemployment rate environment initially above pre-COVID-19 levels at 4.8% but falling below pre-COVID-19 levels by the end of the forecast period to 3.5%. Northeast GDP’s annualized growth (on a quarterly basis) was expected to start the first quarter of 2022 at approximately 9% and hover around 5% by the middle and end of the forecast period. The alternative downside scenario assumed deteriorated economic and pandemic related conditions from the baseline outlook. Under this scenario, northeast unemployment rose from 5.7% in the fourth quarter of 2021 to a peak of 8% in the first quarter of 2023, remaining around or above 7% for the entire forecast period. The alternative upside scenario incorporated a more optimistic outlook than the baseline scenario, with a swift return to full employment by the second quarter of 2022 and with northeast unemployment moving down to 3.1% by the end of the forecast period. These scenarios and their respective weightings are evaluated at each measurement date and reflect management’s expectations as of December 31, 2021. At December 31, 2021, the weightings were 60%, 10% and 30% for the baseline, upside and downside economic forecasts, respectively. Additional adjustments were made for COVID-19 related factors not incorporated in the forecasts, such as the mitigating impact of unprecedented stimulus in the second and third quarters of 2020, including direct payments to individuals, increased unemployment benefits, the Company’s loan deferral and modification initiatives and various government sponsored loan programs. The Company also continued to monitor the level of criticized and classified loans in the fourth quarter of 2021 compared to the level contemplated by the model during similar, historical economic conditions, and an adjustment was made to estimate potential additional losses above modeled losses. Additionally, qualitative adjustments were made for Moody’s baseline economic forecast to include impacts of the Build Back Better Act not passing by December 31, 2021 and to address potential economic deterioration due to Omicron, as well as isolated model limitations related to modeled outputs given abnormally high retail sales and business output growth rates in historical periods. These factors were considered through separate quantitative processes and incorporated into the estimate of current expected credit losses at December 31, 2021. There were no loans purchased with credit deterioration during the nine months ended September 30, 2022 or the year ended December 31, 2021. During 2022, the Company purchased $8.0 million of residential loans at a slight discount and $50.1 million in consumer loans at par. The allowance for credit losses recorded for these loans on the purchase date was $3.2 million. During 2021, the Company purchased $58.9 million of residential loans at a 2%-5% premium and $92.5 million in consumer loans at par. The allowance for credit losses recorded for these loans on the purchase date was $6.8 million. The Company made a policy election to report AIR in the other assets line item on the balance sheet. AIR on loans totaled $21.2 million at September 30, 2022 and $19.5 million at December 31, 2021 and there was no estimated allowance for credit losses related to AIR as of September 30, 2022 and December 31, 2021. Individually Evaluated Loans As of September 30, 2022, there were four relationships identified to be evaluated for loss on an individual basis which, in aggregate, had an amortized cost basis of $4.3 million, with no allowance for credit loss. As of December 31, 2021, there were five relationships identified to be evaluated for loss on an individual basis with an aggregate amortized cost basis of $10.2 million and no allowance for credit loss. The decrease in the amortized cost basis on an individual basis from December 31, 2021 to September 30, 2022 was primarily due to principal payments and resolution of one relationship in which the cost basis was substantially collected and the related $0.8 million allowance for credit losses was reversed. Credit Quality Indicators The Company has developed an internal loan grading system to evaluate and quantify the Company’s loan portfolio with respect to quality and risk. The system focuses on, among other things, financial strength of borrowers, experience and depth of borrower’s management, primary and secondary sources of repayment, payment history, nature of the business and outlook on particular industries. The internal grading system enables the Company to monitor the quality of the entire loan portfolio on a consistent basis and provide management with an early warning system, which facilitates recognition and response to problem loans and potential problem loans. Commercial Grading System For Commercial and Industrial (“C&I”), Paycheck Protection Program (“PPP”) and Commercial Real Estate (“CRE”) loans, the Company uses a grading system that relies on quantifiable and measurable characteristics when available. This includes comparison of financial strength to available industry averages, comparison of transaction factors (loan terms and conditions) to loan policy and comparison of credit history to stated repayment terms and industry averages. Some grading factors are necessarily more subjective such as economic and industry factors, regulatory environment and management. C&I and CRE loans are graded Doubtful, Substandard, Special Mention and Pass. Doubtful A Doubtful loan has a high probability of total or substantial loss, but because of specific pending events that may strengthen the asset, its classification as a loss is deferred. Doubtful borrowers are usually in default, lack adequate liquidity or capital and lack the resources necessary to remain an operating entity. Pending events can include mergers, acquisitions, liquidations, capital injections, the perfection of liens on additional collateral, the valuation of collateral and refinancing. Generally, pending events should be resolved within a relatively short period and the ratings will be adjusted based on the new information. Nonaccrual treatment is required for Doubtful assets because of the high probability of loss. Substandard Substandard loans have a high probability of payment default or they have other well-defined weaknesses. They require more intensive supervision by bank management. Substandard loans are generally characterized by current or expected unprofitable operations, inadequate debt service coverage, inadequate liquidity and/or marginal capitalization. Repayment may depend on collateral or other credit risk mitigants. For some Substandard loans, the likelihood of full collection of interest and principal may be in doubt and those loans should be placed on nonaccrual. Although Substandard assets, in the aggregate, will have a distinct potential for loss, an individual asset’s loss potential does not have to be distinct for the asset to be rated Substandard. Special Mention Special Mention loans have potential weaknesses that may, if not checked or corrected, weaken the asset or inadequately protect the Company’s position at some future date. These loans pose elevated risk, but their weakness does not yet justify a Substandard classification. Borrowers may be experiencing adverse operating trends (e.g., declining revenues or margins) or may be struggling with an ill-proportioned balance sheet (e.g., increasing inventory without an increase in sales, high leverage, and/or tight liquidity). Adverse economic or market conditions, such as interest rate increases or the entry of a new competitor, may also support a Special Mention rating. Although a Special Mention loan has a higher probability of default than a Pass asset, its default is not imminent. Pass Loans graded as Pass encompass all loans not graded as Doubtful, Substandard or Special Mention. Pass loans are in compliance with loan covenants and payments are generally made as agreed. Pass loans range from superior quality to fair quality. Pass loans also include any portion of a government guaranteed loan, including PPP loans. Consumer and Residential Grading System Consumer and Residential loans are graded as either Nonperforming or Performing. Nonperforming Nonperforming loans are loans that are (1) over 90 days past due and interest is still accruing or (2) on nonaccrual status. Performing All loans not meeting any of the above criteria are considered Performing. Allowance for Credit Losses on Off-Balance Sheet Credit Exposures The allowance for losses on unfunded commitments totaled $5.3 million as of September 30, 2022, compared to $5.1 million as of December 31, 2021.
Troubled Debt Restructuring	Troubled Debt Restructuring When the Company modifies a loan in a TDR, such modifications generally include one or a combination of the following: an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk; a temporary reduction in the interest rate; or a change in scheduled payment amount. Residential and Consumer TDRs occurring during 2022 and 2021 were due to reductions in the interest rate and/or extensions of the term. An allowance for impaired commercial and consumer loans that have been modified in a TDR is measured based on the present value of the expected future cash flows, discounted at the contractual interest rate of the original loan agreement, except when the sole (remaining) source of repayment for the loan is the operation or liquidation of the collateral. In these cases, management uses the current fair value of the collateral, less selling costs. If management determines that the value of the modified loan is less than the recorded investment in the loan, an impairment charge would be recorded. The Company began offering loan modifications to assist borrowers during the COVID-19 national emergency. The Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”), along with a joint agency statement issued by banking regulatory agencies, provides that modifications made in response to COVID-19 do not need to be accounted for as a TDR. The Company evaluated the modification programs provided to its borrowers and concluded the modifications were generally made in accordance with the CARES Act guidance to borrowers who were in good standing prior to the COVID-19 pandemic and are not required to be designated as TDRs.

The Company also assumed supplemental retirement plans for former executives of Alliance Financial Corporation (“Alliance”) when the Company acquired Alliance. These supplemental employee retirement plans and the Plan are collectively referred to herein as “Pension Benefits”. In addition, the Company provides certain health care benefits for retired employees. Benefits were accrued over the employees’ active service period. Only employees that were employed by the Company on or before January 1, 2000 are eligible to receive post-retirement health care benefits. In addition, the Company assumed post-retirement medical and life insurance benefits for certain Alliance employees, retirees and their spouses, if applicable, in the Alliance acquisition. These post-retirement benefits are referred to herein as “Other Benefits”. The Company made no voluntary contributions to the pension and other benefits plans during the three and nine months ended September 30, 2022 and 2021.

Earnings Per Share [Abstract]
Earnings Per Share	Basic earnings per share (“EPS”) excludes dilution and is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity (such as the Company’s dilutive stock options and restricted stock units).

Fair Value Measurements and Fair Value of Financial Instruments (Policies)	9 Months Ended

Fair Value Measurements and Fair Value of Financial Instruments [Abstract]
Fair Value of Financial Instruments, Policy	GAAP states that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value measurements are not adjusted for transaction costs. A fair value hierarchy exists within GAAP 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 are described below: Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2 - Quoted prices for similar assets or liabilities in active markets, quoted prices in markets that are not active or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and Level 3 - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (e.g., supported by little or no market activity). A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The types of instruments valued based on quoted market prices in active markets include most U.S. government and agency securities, many other sovereign government obligations, liquid mortgage products, active listed equities and most money market securities. Such instruments are generally classified within Level 1 or Level 2 of the fair value hierarchy. The Company does not adjust the quoted prices for such instruments. The types of instruments valued based on quoted prices in markets that are not active, broker or dealer quotations or quote from alternative pricing sources with reasonable levels of price transparency include most investment-grade and high-yield corporate bonds, less liquid mortgage products, less liquid agency securities, less liquid listed equities, state, municipal and provincial obligations and certain physical commodities. Such instruments are generally classified within Level 2 of the fair value hierarchy. Certain common equity securities are reported at fair value utilizing Level 1 inputs (exchange quoted prices). Other investment securities are reported at fair value utilizing Level 1 and Level 2 inputs. The prices for Level 2 instruments are obtained through an independent pricing service or dealer market participants with whom the Company has historically transacted both purchases and sales of investment securities. Prices obtained from these sources include prices derived from market quotations and matrix pricing. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. Management reviews the methodologies used by its third-party providers in pricing the securities. Level 3 is for positions that are not traded in active markets or are subject to transfer restrictions. Valuations are adjusted to reflect illiquidity and/or non-transferability and such adjustments are generally based on available market evidence. In the absence of such evidence, management’s best estimate will be used. Management’s best estimate consists of both internal and external support on certain Level 3 investments. Subsequent to inception, management only changes Level 3 inputs and assumptions when corroborated by evidence such as transactions in similar instruments, completed or pending third-party transactions in the underlying investment or comparable entities, subsequent rounds of financing, recapitalizations and other transactions across the capital structure, offerings in the equity or debt markets and changes in financial ratios or cash flows. GAAP requires disclosure of assets and liabilities measured and recorded at fair value on a non-recurring basis such as goodwill, loans held for sale, other real estate owned, collateral-dependent impaired loans and HTM securities. The non-recurring fair value measurements recorded during the three and nine month periods ended September 30, 2022 and the year ended December 31, 2021 were related to impaired loans, write-downs of other real estate owned and write-down of branch assets to fair value. The Company uses the fair value of underlying collateral, less costs to sell, to estimate the allowance for credit losses for individually evaluated collateral dependent loans. The appraisals may be adjusted by management for qualitative factors such as economic conditions and estimated liquidation expenses ranging from 10% to 50%. Based on the valuation techniques used, the fair value measurements for collateral dependent individually evaluated loans are classified as Level 3. Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing on and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. For example, the Company has a substantial wealth operation that contributes net fee income annually. The wealth management operation is not considered a financial instrument and its value has not been incorporated into the fair value estimates. Other significant assets and liabilities include the benefits resulting from the low-cost funding of deposit liabilities as compared to the cost of borrowing funds in the market and premises and equipment. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimate of fair value. HTM Securities The fair value of the Company’s HTM securities is primarily measured using information from a third-party pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. Net Loans Net loans include portfolio loans and loans held for sale. Loans were first segregated by type and then further segmented into fixed and variable rate and loan quality categories. Expected future cash flows were projected based on contractual cash flows, adjusted for estimated prepayments, including credit risk, illiquidity risk and other market factors to calculate the exit price fair value in accordance with ASC 820. Time Deposits The fair value of time deposits was estimated using a discounted cash flow approach that applies prevailing market interest rates for similar maturity instruments. The fair values of the Company’s time deposit liabilities do not take into consideration the value of the Company’s long-term relationships with depositors, which may have significant value. Long-Term Debt The fair value of long-term debt was estimated using a discounted cash flow approach that applies prevailing market interest rates for similar maturity instruments. Subordinated Debt The fair value of subordinated debt has been measured using the observable market price as of the period reported. Junior Subordinated Debt The fair value of junior subordinated debt has been estimated using a discounted cash flow analysis.
