2. | Summary of Significant Accounting Policies

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. 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 GAAP and in accordance with the instructions for the Quarterly Report on Form 10-Q and Article 10 of Regulation S-X as promulgated by the 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 2023 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 the current period presentation. The Company has evaluated subsequent events for potential recognition and/or disclosure, and none were 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.
Estimates associated with the allowance for credit losses and pension accounting are particularly susceptible to material change in the near term.

3. | Recent Accounting Pronouncements

Accounting Standards Issued Not Yet Adopted
In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements, which amends the disclosure or presentation requirements related to various subtopics in the FASB Accounting Standards Codification. The ASU was issued in response to the SEC’s August 2018 final rule that updated and simplified disclosure requirements that the SEC believed were redundant, duplicative, overlapping, outdated, or superseded. The new guidance is intended to align GAAP requirements with those of the SEC. The ASU will become effective on the earlier of the date on which the SEC removes its disclosure requirements for the related disclosure or June 30, 2027. Early adoption is not permitted. Aside from meeting the new disclosure requirements, the adoption is not expected to have a material impact on the consolidated financial statements.
In November 2023, the FASB issued ASU 2023-07, Improvements to Reportable Segment Disclosures, to improve the reportable segment disclosure requirements by requiring annual and interim disclosure of incremental segment information. In addition, the amendments will enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment and include other disclosure requirements. The amendments in this ASU are effective for the Company for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024, and early adoption is permitted. Aside from meeting the new disclosure requirements, the adoption is not expected to have a material impact on the consolidated financial statements.

Table of Contents
In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, that addresses requests for improved income tax disclosures from investors, lenders, creditors and other allocators of capital that use the financial statements to make capital allocation decisions. The ASU requires enhanced disclosures primarily related to existing rate reconciliation and income taxes paid information to help investors better assess how the Company’s operations and related tax risks and tax planning and operational opportunities affect the Company’s tax rate and prospects for future cash flows. The ASU 2023-09 improves the transparency of income tax disclosures. The amendments in this ASU are effective for the Company on January 1, 2025 and should be applied on a prospective basis. Retrospective application and early adoption are permitted. Aside from meeting the new disclosure requirements, the adoption is not expected to have a material impact on the consolidated financial statements.

4. | Acquisitions

Pending Acquisition of Evans Bancorp, Inc.
On September 9, 2024, the Company and the Bank, entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Evans and Evans Bank, Evans’s subsidiary, pursuant to which the Company will acquire Evans. Evans, with assets of approximately $2.28 billion at September 30, 2024, is headquartered in Williamsville, New York. Its primary subsidiary, Evans Bank, is a federally-chartered national banking association with 18 banking locations in Western New York.
Subject to the terms and conditions of the Merger Agreement, which has been approved by the boards of directors of each party, Evans will merge with and into the Company, with the Company as the surviving entity, and immediately thereafter, Evans Bank will merge with and into the Bank, with the Bank as the surviving bank (the “Merger”).
Under the terms of the Merger Agreement, each outstanding share of Evans common stock will be converted into the right to receive 0.91 shares of the Company’s common stock. The Merger is subject to customary closing conditions, including the receipt of regulatory approvals and approval by the shareholders of Evans, and is expected to close in the second quarter of 2025.
Prior Period Acquisitions
On August 11, 2023, the Company completed the acquisition of Salisbury through the merger of Salisbury with and into the Company, with the Company surviving the merger, for $161.7 million in stock. Salisbury Bank, Salisbury’s subsidiary, was a Connecticut-chartered commercial bank headquartered in Lakeville, Connecticut with 13 banking offices. The acquisition enhanced the Company’s presence in Massachusetts’ Berkshire county, and extended its footprint into New York’s Dutchess, Orange and Ulster counties and into Connecticut’s Litchfield county. In connection with the acquisition, the Company issued 4.32 million shares of common stock and acquired approximately $1.46 billion of identifiable assets. Preliminary goodwill of $78.1 million was recognized during the quarter ended September 30, 2023 as a result of the merger and is not amortizable or deductible for tax purposes. During the fourth quarter of 2023, the Company revised the estimated fair value of premises and equipment, net and related deferred income taxes based upon receipt of land and building appraisals, which resulted in a $1.7 million increase in goodwill. Total goodwill of $79.7 million was recognized as a result of the merger. The effects of the acquired assets and liabilities have been included in the consolidated financial statements since that date. As a result of the full integration of the operations of Salisbury, it is not practicable to determine all revenue or net income included in the Company’s operating results relating to Salisbury since the date of acquisition as Salisbury results cannot be separately identified.
The Company determined that this acquisition constituted a business combination and therefore was accounted for using the acquisition method of accounting. Accordingly, as of the date of the acquisition, the Company recorded the assets acquired, liabilities assumed and consideration paid at fair value based on management’s best estimates using information available at the date of the acquisition and these estimates are subject to adjustment based on updated information not available at the time of the acquisition. The amount of goodwill arising from the acquisition consists largely of the synergies and economies of scale expected from combining the operations of the Company with Salisbury.

The following is a description of the valuation methodologies used to estimate the fair values of major categories of assets acquired and liabilities assumed. The Company used an independent valuation specialist to assist with the determination of fair values for certain acquired assets and assumed liabilities.
Cash and due from banks - The estimated fair value was determined to approximate the carrying amount of these assets.
Securities available for sale - The estimated fair value of the investment portfolio was based on quoted market prices and dealer quotes. The investment securities were sold immediately after the merger and no gains or losses were recorded.
Loans - The estimated fair value of loans were based on a discounted cash flow methodology applied on a pooled basis for non-PCD loans and for PCD loans. The valuation considered underlying characteristics including loan type, term, rate, payment schedule and credit rating. Other factors included assumptions related to prepayments, probability of default and loss given default. The discount rates applied were based on a build-up approach considering the funding mix, servicing costs, liquidity premium and factors related to performance risk.
Core deposit intangible - The core deposit intangible was valued utilizing the cost savings method approach, which recognizes the cost savings represented by the expense of maintaining the core deposit base versus the cost of an alternative funding source. The valuation incorporates assumptions related to account retention, discount rates, deposit interest rates, deposit maintenance costs and alternative funding rates.
Wealth management customer intangible - The wealth management customer intangible was valued utilizing the income approach, which employs a present value analysis, which calculates the expected after-tax cash flow benefits of the net revenues generated by the acquired customers over the expected lives of the acquired customers, discounted at a long-term market-oriented after-tax rate of return on investment. The value assigned to the acquired customers represents the future economic benefit from acquiring the customers (net of operating expenses).
Deposits - The fair value of noninterest bearing demand deposits, interest checking, money market and savings deposit accounts from Salisbury were assumed to approximate the carrying value as these accounts have no stated maturity and are payable on demand. Certificate of deposit (time deposit accounts) were valued at the present value of the certificates’ expected contractual payments discounted at market rates for similar certificates.

Table of Contents
Borrowings - The estimated fair value of short-term borrowings was determined to approximate stated value. Subordinated debt was valued using a discounted cash flow approach incorporating a discount rate that incorporated similar terms, maturity and credit rating.
Accounting for Acquired Loans - Acquired loans are classified into two categories: PCD loans and non-PCD loans. PCD loans are defined as a loan or group of loans that have experienced more than insignificant credit deterioration since origination. Non-PCD loans had an allowance established on acquisition date, which was recognized as an expense through the provision for credit losses. For PCD loans, an allowance was recognized by adding it to the fair value of the loan, which is the amortized cost. There is no provision for credit loss expense recognized on PCD loans because the initial allowance is established by grossing-up the amortized cost of the PCD loan. The allowance for credit losses on non-PCD loans of $8.8 million was recorded through the provision for loan losses within the unaudited interim consolidated statements of income. The following table provides details related to the fair value of acquired PCD loans.

(In thousands) |  | PCD Loans |
Par value of PCD loans at acquisition |  | $ | 219,076 |
Allowance for credit losses at acquisition |  |  | 5,772 |
Discount at acquisition |  |  | (24,512 | )
Fair value of PCD loans at acquisition |  | $ | 200,336 |

Direct costs related to the acquisition were expensed as incurred. Acquisition integration-related expenses were $7.9 million and $9.7 million during the three and nine months ended September 30, 2023, respectively. These amounts have been separately stated in the unaudited interim consolidated statements of income and are included in operating activities in the unaudited interim consolidated statements of cash flows.
Supplemental Pro Forma Financial Information (Unaudited)
The following table presents certain unaudited pro forma financial information for illustrative purposes only, for the three and nine months ended September 30, 2023, as if Salisbury had been acquired on January 1, 2023. This unaudited pro forma information combines the historical results of Salisbury with the Company’s consolidated historical results and includes certain adjustments reflecting the estimated impact of certain fair value adjustments for the respective periods. The pro forma information is not indicative of what would have occurred had the acquisition occurred as of the beginning of the year prior to the acquisition. The unaudited pro forma information does not consider any changes to the provision expense resulting from recording loan assets at fair value, cost savings or business synergies. As a result, actual amounts would have differed from the unaudited pro forma information presented and the differences could be significant.

|  | Pro Forma (Unaudited) |
|  | Three Months Ended |  |  | Nine Months Ended |
(In thousands) |  | September 30, 2023 |  |  | September 30, 2023 |
Total revenue, net of interest expense |  | $ | 130,881 |  |  | $ | 404,580 |
Net income |  |  | 12,182 |  |  |  | 81,859 |

Other Acquisitions

Maturities of mortgage-backed, collateralized mortgage obligations and asset-backed securities are based on their estimated average lives. Actual maturities may differ from estimated average lives or contractual maturities because, in certain cases, borrowers have the right to call or prepay obligations, with or without call or prepayment penalties.
Except for U.S. government securities and government-sponsored enterprises securities, there were no holdings, when taken in the aggregate, of any single issuer that exceeded 10% of consolidated stockholders’ equity at September 30, 2024 and December 31, 2023.

The Company does not believe that the AFS securities in an unrealized loss position as of September 30, 2024 and December 31, 2023, which consisted of 383 and 388 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, 2024 and December 31, 2023, 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, nor is it more likely than not that the Company will be required to sell these securities before recovery of its amortized cost basis, which may be at maturity. The Company elected to exclude AIR from the amortized cost basis of debt securities. AIR on AFS debt securities totaled $4.1 million at September 30, 2024 and $3.9 million at December 31, 2023, and is excluded from the estimate of credit losses and is reported in the other assets financial statement line.
None of the Bank’s HTM debt securities were past due or on nonaccrual status as of September 30, 2024 and December 31, 2023. There was no accrued interest reversed against interest income for the three and nine months ended September 30, 2024 or the year ended December 31, 2023 as all securities remained in accrual status. In addition, there were no collateral-dependent HTM debt securities as of September 30, 2024 and December 31, 2023. There was no allowance for credit losses on HTM securities as of September 30, 2024 and December 31, 2023. As of September 30, 2024 and December 31, 2023, 66% 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, which 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, 2024 and December 31, 2023. The remaining HTM debt securities at September 30, 2024 and December 31, 2023 were comprised of state and municipal obligations with bond ratings of A to AAA. Based on the Company's CECL methodology, the expected credit loss on the HTM municipal bond portfolio was deemed immaterial, therefore no allowance for credit loss was recorded as of September 30, 2024 and December 31, 2023. AIR on HTM debt securities totaled $3.8 million at September 30, 2024 and $4.7 million at December 31, 2023 and is excluded from the estimate of credit losses and reported in the other assets financial statement line.

Included in the above loans are net deferred loan origination (fees) costs totaling ($72.8) million and ($98.2) million at September 30, 2024 and December 31, 2023, respectively.

7. | Allowance for Credit Losses and Credit Quality of Loans

The allowance for credit losses totaled $119.5 million at September 30, 2024, compared to $114.4 million at December 31, 2023. The allowance for credit losses as a percentage of loans was 1.21% at September 30, 2024, compared to 1.19% at December 31, 2023.
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, 2024 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. At September 30, 2024, the weightings were 80% and 20% for the baseline and downside economic forecasts, respectively. The baseline outlook reflects an economic environment where the Northeast unemployment rate increases slightly but remains around 4.1% during the forecast period. Northeast GDP’s annualized growth (on a quarterly basis) is expected to start the fourth quarter of 2024 at approximately 3.9% and remains relatively stable during the forecast period. Key assumptions in the baseline economic outlook included the Federal Reserve cutting rates at the September and December meetings, the economy remaining at full employment, and continued tapering of the Federal Reserve balance sheet. 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 2024 to a peak of 7.5% in the fourth quarter of 2025. These scenarios and their respective weightings are evaluated at each measurement date and reflect management’s expectations as of September 30, 2024. Additional adjustments were made for factors not incorporated in the forecasts or the model, such as loss rate expectations for certain loan pools, considerations for inflation, and recent trends in asset value indices. Additional monitoring for industry concentrations, loan growth, and policy exceptions was also conducted.

The quantitative model as of June 30, 2024 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. At June 30, 2024, the weightings were 80% and 20% for the baseline and downside economic forecasts, respectively. The baseline outlook reflected an economic environment where the Northeast unemployment rate increases slightly from 4.0% to 4.1% during the forecast period. Northeast GDP’s annualized growth (on a quarterly basis) was expected to start the third quarter of 2024 at approximately 3.7% and increase slightly to 3.8% before the end of the forecast period. Key assumptions in the baseline economic outlook included the Federal Reserve cutting rates with two 25 basis point cuts at the September and December meetings, the economy remaining at full employment, and continued tapering of the Federal Reserve balance sheet. The alternative downside scenario assumed deteriorated economic conditions from the baseline outlook. Under this scenario, Northeast unemployment rises from 4.0% in the second quarter of 2024 to a peak of 7.2% in the fourth quarter of 2025. These scenarios and their respective weightings are evaluated at each measurement date and reflect management’s expectations as of June 30, 2024. Additional adjustments were made for factors not incorporated in the forecasts or the model, such as loss rate expectations for certain loan pools, considerations for inflation, and recent trends in asset value indices. Additional monitoring for industry concentrations, loan growth, and policy exceptions was also conducted.
The methodology for prepayment assumptions was revised during the second quarter of 2024 from a static, current rate experience approach to one that includes both current experience and long-term average behavior. The change to the methodology increased the allowance for loan losses by approximately 3% as of June 30, 2024. The longer-average effective life portfolios such as the residential mortgage and residential solar segments experienced a greater impact resulting from the change in methodology. The change in prepayment methodology provided an improved estimate of expected prepayments, particularly for the longer-lived portfolios.
The quantitative model as of December 31, 2023 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. At December 31, 2023, the weightings were 70% and 30% for the baseline and downside economic forecasts, respectively. The baseline outlook reflected an unemployment rate environment starting at 3.8% and increasing slightly during the forecast period to 4.1%. Northeast GDP’s annualized growth (on a quarterly basis) was expected to start the first quarter of 2024 at approximately 3.7% before decreasing to a low of 2.9% in the third quarter of 2024 and then increasing to 3.8% by the end of the forecast period. Other utilized economic variable forecasts are mixed compared to the prior year, with retail sales improving, business output mixed and housing starts down. Key assumptions in the baseline economic outlook included currently being in a full employment economy, continued tapering of the Federal Reserve balance sheet and the FOMC beginning to cut rates in the second quarter of 2024. The alternative downside scenario assumed deteriorated economic conditions from the baseline outlook. Under this scenario, Northeast unemployment increases to a peak of 7.0% in the first quarter of 2025. These scenarios and their respective weightings are evaluated at each measurement date and reflect management’s expectations as of December 31, 2023. Additional qualitative adjustments were made for factors not incorporated in the forecasts or the model, such as loss rate expectations for certain loan pools, considerations for inflation and recent trends in asset value indices. Additional monitoring for industry concentrations, loan growth and policy exceptions was also conducted.
There were no loans purchased with credit deterioration during the nine months ended September 30, 2024. There were $219.5 million of PCD loans acquired from Salisbury during the year ended December 31, 2023, which resulted in an allowance for credit losses at acquisition of $5.8 million. During the nine months ended September 30, 2024, the Company purchased $2.0 million of residential loans at a 7.0% premium with a $20 thousand allowance for credit losses recorded for these loans. During 2023, the Company purchased $3.8 million of residential loans at a 7.0% premium with a $31 thousand allowance for credit losses recorded for these loans.
The Company made a policy election to report AIR in the other assets line item on the consolidated balance sheets. AIR on loans totaled $34.2 million at September 30, 2024 and $34.1 million at December 31, 2023 with no estimated allowance for credit losses related to AIR as of September 30, 2024 and December 31, 2023 as it is excluded from amortized cost.
The Company’s January 1, 2023 adoption of ASU 2022-02, Financial Instruments - CECL Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures resulted in an insignificant change to its methodology for estimating the allowance for credit losses on TDRs. The ASU eliminated the guidance on 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 decrease in allowance for credit loss on TDR loans relating to adoption of ASU 2022-02 was $0.6 million.

The allowance for credit losses as of September 30, 2024 was consistent with the allowance estimates as of June 30, 2024 and increased compared to the allowance estimates as of December 31, 2023. The increase from December 31, 2023 was primarily due to providing for current year loan growth, the slowing of prepayment speed assumptions, including the changes in prepayment model assumptions and an additional specific reserve established in the second quarter of 2024 relating to a commercial relationship individually evaluated for credit loss. These increases to the allowance for credit losses were partially offset by the change in forecast scenario weightings from 70% baseline and 30% downside to 80% baseline and 20% downside, and the shift in loan composition driven by other consumer and residential solar portfolios that are in a planned run-off status.
The allowance for credit losses as of September 30, 2023 incorporated the recording of $14.5 million of allowance for acquired Salisbury loans as of the acquisition date, which included both the $8.8 million of non-PCD allowance recognized through the provision for loan losses and the $5.8 million of PCD allowance reclassified from loans.
Individually Evaluated Loans
The threshold for evaluating classified, commercial and commercial real estate loans risk graded substandard or doubtful, and nonperforming loans individually evaluated for credit loss is $1.0 million. As of September 30, 2024, two relationships were identified for individual credit loss evaluation which had an amortized cost basis of $16.6 million, with $1.7 million of allowance for credit loss. As of December 31, 2023, the same two relationships were identified for individual credit loss evaluation which had an amortized cost basis of $17.3 million, with no allowance for credit loss. As of September 30, 2024 and December 31, 2023, there were $1.3 million and $17.3 million, respectively, of loans in nonaccrual status that were individually evaluated for expected credit loss without an allowance for credit losses.

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, focusing on, among other things, borrowers financial strength, experience and depth of borrower’s management, primary and secondary sources of repayment, payment history, nature of the business and industry outlook. 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 C&I and 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.

Table of Contents
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 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 (i.e., declining revenues or margins) or may be struggling with an ill-proportioned balance sheet (i.e., 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 Paycheck Protection Program 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.

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. These post-retirement benefits are referred to herein as “Other Benefits.”
Accounting standards require an employer to: (1) recognize the overfunded or underfunded status of defined benefit post-retirement plans, which is measured as the difference between plan assets at fair value and the benefit obligation, as an asset or liability in its balance sheet; (2) recognize changes in that funded status in the year in which the changes occur through comprehensive income; and (3) measure the defined benefit plan assets and obligations as of the date of its year-end balance sheet.
The Company made no voluntary contributions to the Pension Benefits and Other Benefits plans during the three and nine months ended September 30, 2024 and 2023.
The components of expense for Pension Benefits and Other Benefits are set forth below:

10. | Earnings Per Share

Basic 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:

12. | 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 may enter 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 is 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 resulting 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 as hedging relationships. Interest rate swaps are recorded within other assets or other liabilities on the consolidated balance sheets 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 statements 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 clears certain derivative transactions through the CME. 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.

In 2017, the U.K. Financial Conduct Authority announced its intention to stop compelling banks to submit rates for the calculation of LIBOR after 2021. In 2022, the Federal Reserve adopted a final rule implementing the Adjustable Interest Rate (LIBOR) Act by identifying benchmark rates based on SOFR that replaced LIBOR in certain financial contracts after June 30, 2023. In 2023, the Company transitioned all of its financial instruments to an alternative benchmark rate.
As of September 30, 2024 and December 31, 2023, the Company had twenty and twelve 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.
The following table summarizes the derivatives outstanding:

(1) | Netting adjustments represents the amounts recorded to convert derivative 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.

(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.

The following table indicates the gain or loss recognized in income on derivatives not designated as a hedging relationship:

13. | 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 (i.e., supported by little or no market activity).
29

Table of Contents
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:

Table of Contents
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 loans individually evaluated for expected credit losses and HTM securities. Loans with fair value of $3.0 million as of September 30, 2024 were individually evaluated for expected credit losses where the amortized cost was adjusted to fair value. There were no loans individually evaluated for expected credit losses where the amortized cost was adjusted to fair value as of December 31, 2023. 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.

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, and those expected future cash flows also includes 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.

14. | 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 instruments. 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 creditworthiness. Commitments to extend credit and unused lines of credit totaled $2.86 billion at September 30, 2024 and $2.68 billion at December 31, 2023.
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 $47.5 million at September 30, 2024 and $44.7 million at December 31, 2023. As of September 30, 2024 and December 31, 2023, the fair value of the Company’s standby letters of credit was not significant.

Critical Accounting Estimates
SEC guidance requires disclosure of “critical accounting estimates.” The SEC defines “critical accounting estimates” as those 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 the financial condition or results of operations of the registrant. The Company follows financial accounting and reporting policies that are in accordance with GAAP. The more significant of these policies are summarized in Note 1 to the consolidated financial statements presented in our 2023 Annual Report on Form 10-K. Refer to Note 3 to the unaudited interim consolidated financial statements in this Quarterly Report on Form 10-Q for recently adopted accounting standards. Not all significant accounting policies require management to make difficult, subjective or complex judgments. The allowance for credit losses and the allowance for unfunded commitments policies are deemed to meet the SEC’s definition of a critical accounting estimate.
Allowance for Credit Losses and Unfunded Commitments
The allowance for credit losses consists of the allowance for credit losses and the allowance for losses on unfunded commitments. The measurement of CECL on financial instruments requires an estimate of the credit losses expected over the life of an exposure (or pool of exposures). The estimate of expected credit losses under the CECL methodology is based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. Historical loss experience is generally the starting point for estimating expected credit losses. The Company then considers whether the historical loss experience should be adjusted for asset-specific risk characteristics or current conditions at the reporting date that did not exist over the period from which historical experience was used. Finally, the Company considers forecasts about future economic conditions that are reasonable and supportable. The allowance for credit losses for loans, as reported in our consolidated statements of financial condition, is adjusted by an expense for credit losses, which is recognized in earnings, and reduced by the charge-off of loan amounts, net of recoveries. The allowance for losses on unfunded commitments represents the expected credit losses on off-balance sheet commitments such as unfunded commitments to extend credit and standby letters of credit. However, a liability is not recognized for commitments unconditionally cancellable by the Company. The allowance for losses on unfunded commitments is determined by estimating future draws and applying the expected loss rates on those draws.
Management of the Company considers the accounting policy relating to the allowance for credit losses to be a critical accounting estimate given the uncertainty in evaluating the level of the allowance required to cover management’s estimate of all expected credit losses over the expected contractual life of our loan portfolio. Determining the appropriateness of the allowance is complex and requires judgment by management about the effect of matters that are inherently uncertain. Subsequent evaluations of the then-existing loan portfolio, in light of the factors then prevailing, may result in significant changes in the allowance for credit losses in those future periods. While management’s current evaluation of the allowance for credit losses indicates that the allowance is appropriate, the allowance may need to be increased under adversely different conditions or assumptions. The impact of utilizing the CECL methodology to calculate the reserve for credit losses will be significantly influenced by the composition, characteristics and quality of our loan portfolio, as well as the prevailing economic conditions and forecasts utilized. Material changes to these and other relevant factors may result in greater volatility to the reserve for credit losses, and therefore, greater volatility to our reported earnings.
One of the most significant judgments involved in estimating the Company’s allowance for credit losses relates to the macroeconomic forecasts used to estimate expected credit losses over the forecast period. As of September 30, 2024, the quantitative model 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. At September 30, 2024, the weightings were 80% and 20% for the baseline and downside economic forecasts, respectively. The baseline outlook reflects an economic environment where the Northeast unemployment rate increases slightly but remains around 4.1% during the forecast period. Northeast GDP’s annualized growth (on a quarterly basis) is expected to start the fourth quarter of 2024 at approximately 3.9% and remains relatively stable during the forecast period. Key assumptions in the baseline economic outlook included the Federal Reserve cutting rates at the September and December meetings, the economy remaining at full employment, and continued tapering of the Federal Reserve balance sheet. 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 2024 to a peak of 7.5% in the fourth quarter of 2025. These scenarios and their respective weightings are evaluated at each measurement date and reflect management’s expectations as of September 30, 2024. Additional adjustments were made for factors not incorporated in the forecasts or the model, such as loss rate expectations for certain loan pools, considerations for inflation, and recent trends in asset value indices. Additional monitoring for industry concentrations, loan growth, and policy exceptions was also conducted. To demonstrate the sensitivity of the allowance for credit losses estimate to macroeconomic forecast weightings assumptions as of September 30, 2024, the Company attributed the change in scenario weightings to the change in the allowance for credit losses, with a 10% decrease to the downside scenario and a 10% increase to the baseline scenario causing a 4% decrease in the overall estimated allowance for credit losses. To further demonstrate the sensitivity of the allowance for credit losses estimate to macroeconomic forecast weightings assumptions as of September 30, 2024, the Company increased the downside scenario to 100% which resulted in a 33% increase in the overall estimated allowance for credit losses.

Net Interest Income
Net interest income is the difference between interest income on earning assets, primarily loans and securities and interest expense on interest-bearing liabilities, primarily deposits and borrowings. Net interest income is affected by the interest rate spread, the difference between the yield on interest-earning assets and cost of interest-bearing liabilities, as well as the volumes of such assets and liabilities. Net interest income is one of the key determining factors in a financial institution’s performance as it is the principal source of earnings.
Net interest income was $101.7 million for the third quarter of 2024, up $4.5 million, or 4.6%, from the previous quarter. The FTE net interest margin was 3.27% for the three months ended September 30, 2024, an increase of 9 bps from the previous quarter. Interest income increased $5.5 million, or 3.6%, as the yield on average interest-earning assets increased 9 bps from the prior quarter to 5.01%, while average interest-earning assets of $12.45 billion increased $79.2 million from the prior quarter, primarily due to organic loan growth slightly offset by a decrease in the average balance of securities. Interest expense was up $1.0 million, or 1.8%, as the cost of interest-bearing liabilities increased 2 bps to 2.60% for the quarter ended September 30, 2024, driven by interest-bearing deposit costs increasing 6 bps, which were partially offset by lower average balances of short-term borrowings. Included in net interest income was $2.7 million of acquisition-related net accretion for the three months ended September 30, 2024 and $2.6 million of acquisition-related net accretion for the three months ended June 30, 2024.
Net interest income was $101.7 million for the third quarter of 2024, up $6.8 million, or 7.1%, from the third quarter of 2023. The FTE net interest margin was 3.27% for the three months ended September 30, 2024, an increase of 6 bps from the third quarter of 2023. Interest income increased $19.1 million, or 14.0%, as the yield on average interest-earning assets increased 38 bps from the same period in 2023 to 5.01%, while average interest-earning assets increased $644.2 million, or 5.5%, from the third quarter of 2023 primarily due to the Salisbury acquisition and organic loan growth. Interest expense increased $12.4 million, or 29.3%, as the cost of interest-bearing liabilities increased 42 bps to 2.60% for the quarter ended September 30, 2024, primarily due to both a 67 bps increase in interest-bearing deposit costs and a $1.13 billion increase in interest-bearing deposits as a result of the Salisbury acquisition, which were partially offset by a decrease of $491.5 million in the average balance of short-term borrowings and the 574 bps rate paid on those borrowings. Included in net interest income was $2.7 million of acquisition-related net accretion for the three months ended September 30, 2024 and $1.4 million of acquisition-related net accretion for the three months ended September 30, 2023.
Net interest income for the nine months ended September 30, 2024 was $294.0 million, up $15.0 million, or 5.4%, from the same period in 2023. FTE net interest margin was 3.20% for the nine months ended September 30, 2024, a decrease of 14 bps from the same period in 2023. Interest income increased $82.1 million, or 22.1%, as the yield on average interest-earning assets increased 49 bps from the same period in 2023 to 4.93%, while average interest-earning assets of $12.36 billion increased $1.13 billion primarily due to the Salisbury acquisition and organic loan growth, partially offset by the decrease in securities. Interest expense was up $67.1 million, or 72.3%, for the nine months ended September 30, 2024 as compared to the same period in 2023 driven by interest-bearing deposit costs increasing 109 bps and a $1.47 billion increase in interest-bearing deposits as a result of the Salisbury acquisition, partially offset by a decrease of $347.0 million in the average balances of short-term borrowings and the 548 bps rate paid on those borrowings. Included in net interest income was $7.8 million of acquisition-related net accretion for the nine months ended September 30, 2024 and $1.4 million of acquisition-related net accretion for the nine months ended September 30, 2023.

(1) | Loans are summarized by business line which do not align to how the Company assesses credit risk in the allowance for credit losses.

Total loans increased by $256.3 million, or 3.5% annualized, from December 31, 2023 to September 30, 2024. Excluding the other consumer and residential solar portfolios that are in a planned run-off status, period end loans increased $384.4 million, or 6.0% annualized. Commercial and industrial loans increased $104.7 million to $1.46 billion; commercial real estate loans increased $165.6 million to $3.79 billion; and total consumer loans decreased $13.9 million to $4.66 billion. Total loans represent approximately 71.6% of assets as of September 30, 2024, as compared to 72.5% as of December 31, 2023.
Loans in the C&I and CRE portfolios consist primarily of loans made to small and medium-sized entities. The Company offers a variety of loan options to meet the specific needs of our commercial customers including term loans, time notes and lines of credit. Such loans are made available to businesses for working capital needs such as inventory and receivables, business expansion, equipment purchases, livestock purchases and seasonal crop expenses. These loans are usually collateralized by business assets such as equipment, accounts receivable and perishable agricultural products, which are exposed to industry price volatility. The Company extends CRE loans to facilitate various real estate transactions, encompassing acquisitions, refinancing, expansions and enhancements to both commercial and agricultural properties. These loans are secured by liens on real estate assets, covering a spectrum of properties including apartments, commercial structures, healthcare facilities and others, whether occupied by owners or non-owners. Risks associated with the CRE portfolio pertain to the borrowers’ capacity to meet interest and principal payments throughout the loan’s duration, as well as their ability to secure financing upon the loan’s maturity. The Company has a risk management framework that includes rigorous underwriting standards, targeted portfolio stress testing, interest rate sensitivities on commercial borrowers and comprehensive credit risk monitoring mechanisms. The Company remains vigilant in monitoring market trends, economic indicators and regulatory developments to promptly adapt our risk management strategies as needed.

Within the CRE portfolio, approximately 81% comprises Non-Owner Occupied CRE, with the remaining 19% being Owner-Occupied CRE. Non-Owner Occupied CRE includes diverse sectors across the Company’s markets such as residential rental properties (43%), and office spaces (18%), along with retail, manufacturing, mixed use, hotels and others. Notably, office CRE loans account for 6% of the total outstanding loans, predominantly serving suburban medical and professional tenants across suburban and small urban markets. These loans carry an average size of $1.9 million, with 10% maturing over the next two years. As of September 30, 2024 and December 31, 2023, the total CRE construction and development loans amounted to $286.9 million and $347.2 million, respectively.
Allowance for Credit Losses, Provision for Loan Losses and Nonperforming Assets
Beginning January 1, 2023, the Company adopted ASU 2022-02 Financial Instruments - CECL Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures which resulted in an insignificant change to the Company’s methodology for estimating the allowance for credit losses on TDRs since December 31, 2022. The January 1, 2023 decrease in the allowance for credit loss on TDR loans relating to the adoption of ASU 2022-02 was $0.6 million, which increased retained earnings by $0.5 million and decreased the deferred tax asset by $0.1 million.
Management considers the accounting policy relating to the allowance for credit losses to be a critical estimate given the degree of judgment exercised in evaluating the level of the allowance required to estimate expected credit losses over the expected contractual life of our loan portfolio and the material effect that such judgments can have on the consolidated results of operations.
The CECL methodology requires an estimate of the credit losses expected over the life of a loan (or pool of loans). The allowance for credit losses is a valuation account that is deducted from, or added to, the loans’ amortized cost basis to present the net, lifetime amount expected to be collected on the loans. Loan losses are charged off against the allowance when management believes a loan balance is confirmed to be uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off.
Required additions or reductions to the allowance for credit losses are made periodically by charges or credits to the provision for loan losses. These are necessary to maintain the allowance at a level which management believes is reasonably reflective of the overall loss expected over the contractual life of the loan portfolio, adjusted for expected prepayments. While management uses available information to recognize losses on loans, additions or reductions to the allowance may fluctuate from one reporting period to another. These fluctuations are reflective of changes in risk associated with portfolio content and/or changes in management’s assessment of any or all of the determining factors discussed above. Management considers the allowance for credit losses to be appropriate based on evaluation and analysis of the loan portfolio.
Management estimates the allowance balance for credit losses using relevant available information, from internal and external sources, related to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Company historical loss experience was supplemented with peer information when there was insufficient loss data for the Company. Significant management judgment is required at each point in the measurement process.
The allowance for credit losses is measured on a collective (pool) basis, with both a quantitative and qualitative analysis that is applied on a quarterly basis, when similar risk characteristics exist. The respective quantitative allowance for each segment is measured using an econometric, discounted probability of default and loss given default modeling methodology in which distinct, segment-specific multi-variate regression models are applied to multiple, probabilistically weighted external economic forecasts. Under the discounted cash flows methodology, expected credit losses are estimated over the effective life of the loans by measuring the difference between the net present value of modeled cash flows and amortized cost basis. After quantitative considerations, management applies additional qualitative adjustments so that the allowance for credit loss is reflective of the estimate of lifetime losses that exist in the loan portfolio at the balance sheet date.
Portfolio segment is defined as the level at which an entity develops and documents a systematic methodology to determine its allowance for credit losses. Upon adoption of CECL, management revised the manner in which loans were pooled for similar risk characteristics. Management developed segments for estimating loss based on type of borrower and collateral which is generally based upon federal call report segmentation and have been combined or subsegmented as needed to ensure loans of similar risk profiles are appropriately pooled.
Additional information about our allowance for credit losses is included in Note 7 to the unaudited interim consolidated financial statements in this Quarterly Report on Form 10-Q as well as in the “Critical Accounting Estimates” section of Management’s Discussion and Analysis of Financial Condition and Results of Operations. The Company’s management considers the allowance for credit losses to be appropriate based on evaluation and analysis of the loan portfolio.

The allowance for credit losses totaled $119.5 million at September 30, 2024, as compared to $120.5 million at June 30, 2024 and $114.6 million at September 30, 2023. The allowance for credit losses as a percentage of loans was 1.21% at September 30, 2024, compared to 1.22% at June 30, 2024 and 1.19% at September 30, 2023. The allowance for credit losses as of September 30, 2024 was consistent with the allowance estimates as of June 30, 2024. The increase in the allowance for credit losses from September 30, 2023 to September 30, 2024 was primarily due to providing for organic loan growth, the slowing of prepayment speed assumptions, including the change in prepayment model assumptions and an additional specific reserve established in the second quarter of 2024 relating to a commercial relationship individually evaluated for credit loss. These increases to the allowance for credit losses were partially offset by a change in forecast scenario weightings from 70% baseline and 30% downside to 80% baseline and 20% downside, and the shift in loan composition driven by other consumer and residential solar portfolios that are in a planned run-off status.
The allowance for credit losses as of September 30, 2023 incorporates the recording of $14.5 million of allowance for acquired Salisbury loans as of the acquisition date, which included both the $8.8 million of non-PCD allowance recognized through the provision for loan losses and the $5.8 million of PCD allowance reclassified from loans.
The allowance for credit losses was 320.21% of nonperforming loans at September 30, 2024, compared to 316.37% at June 30, 2024 and 472.31% at September 30, 2023. The allowance for credit losses was 358.45% of nonaccrual loans at September 30, 2024, compared to 346.71% of nonaccrual loans at June 30, 2024 and 552.67% of nonaccrual loans at September 30, 2023. The decline in the coverage of the allowance to nonperforming and nonaccrual loans from September 30, 2023 to September 30, 2024 largely relates to one nonperforming relationship that is individually evaluated for purposes of the allowance for credit losses which had a $1.7 million specific reserve established during the three months ended June 30, 2024.
The provision for loan losses was $2.9 million for three months ended September 30, 2024, compared to $8.9 million in the prior quarter and $12.6 million for the same period in the prior year. Included in the provision expense for the three months ended September 30, 2023, was $8.8 million of acquisition-related provision for loan losses due to the Salisbury acquisition. Provision expense decreased compared to the prior quarter due lower levels of loan growth the third quarter of 2024 including the run-off of the other consumer and residential solar portfolios, the stabilization of expected prepayment assumptions impacting the expected life of the loan portfolio and a specific reserve established in the prior quarter relating to a commercial relationship previously placed in nonaccrual in the fourth quarter of 2023. Net charge-offs totaled $3.9 million during the three months ended September 30, 2024, compared to net charge-offs of $3.7 million during the second quarter of 2024 and $4.2 million in the third quarter of 2023. Net charge-offs to average loans was 16 bps for the three months ended September 30, 2024, compared to 15 bps for the second quarter of 2024 and 18 bps for the three months ended September 30, 2023.
The provision for loan losses was $17.4 million for the nine months ended September 30, 2024, compared to $20.1 million for the nine months ended September 30, 2023. Provision expense decreased from the same period in the prior year due to the $8.8 million of acquisition-related provision for loan losses due to the Salisbury acquisition recorded during the nine months ended September 30, 2023, partially offset by providing for current year loan growth, the slowing of prepayment speed assumptions in the current year, changes in model assumptions including the extension of the expected duration of the portfolio and a specific reserve related to a commercial relationship previously placed in nonaccrual in the fourth quarter of 2023. Net charge-offs totaled $12.3 million during the nine months ended September 30, 2024, compared to net charge-offs of $11.5 million during the nine months ended September 30, 2023. Net charge-offs to average loans was 17 bps for the nine months ended September 30, 2024, compared to 18 bps for the nine months ended September 30, 2023.
As of September 30, 2024, the unfunded commitment reserve totaled $4.6 million, compared to $4.3 million as of June 30, 2024 and $4.8 million as of September 30, 2023.
Nonperforming assets consist of nonaccrual loans, loans over 90 days past due and still accruing, troubled loans modifications, OREO and nonperforming securities. Loans are generally placed on nonaccrual when principal or interest payments become 90 days past due, unless the loan is well secured and in the process of collection. Loans may also be placed on nonaccrual when circumstances indicate that the borrower may be unable to meet the contractual principal or interest payments. The threshold for evaluating classified commercial and commercial real estate loans risk graded substandard or doubtful, and nonperforming loans individually evaluated for credit loss is $1.0 million. OREO represents property acquired through foreclosure and is valued at the lower of the carrying amount or fair value, less any estimated disposal costs.

Total nonperforming assets were $37.4 million at September 30, 2024, compared to $37.9 million at December 31, 2023 and $24.3 million at September 30, 2023. Nonperforming loans at September 30, 2024 were $37.3 million or 0.38% of total loans, compared with $37.9 million or 0.39% of total loans at December 31, 2023 and $24.3 million or 0.25% of total loans at September 30, 2023. The increase in nonperforming assets from the same period in the prior year was attributable to a diversified, multi-tenant commercial real estate development relationship that was placed into a nonaccrual status in the fourth quarter of 2023, in which NBT is a participant. The relationship is being actively managed, as noted above, a $1.7 million specific reserve was established during the three months ended June 30, 2024 for this relationship. Total nonaccrual loans were $33.3 million or 0.34% of total loans at September 30, 2024, compared to $34.2 million or 0.35% of total loans at December 31, 2023 and $20.7 million or 0.21% of total loans at September 30, 2023. Past due loans as a percentage of total loans was 0.36% at September 30, 2024, up from 0.32% at December 31, 2023 and down from 0.49% at September 30, 2023.
In addition to nonperforming loans discussed above, the Company has also identified approximately $119.9 million in potential problem loans at September 30, 2024 as compared to $87.7 million at December 31, 2023 and $92.4 million at September 30, 2023. Potential problem loans are loans that are currently performing, with a possibility of loss if weaknesses are not corrected. Such loans may need to be disclosed as nonperforming at some time in the future. Potential problem loans are classified by the Company’s loan rating system as “substandard.” Potential problem loans have increased to more normalized levels and the increase primarily relates to a few commercial real estate relationships reflecting changing conditions in commercial real estate markets including construction delays, rising costs and delays in leasing up spaces. The increase in potential problem loans at September 30, 2024 compared to December 31, 2023 and September 30, 2023 is primarily due to the net migration of commercial loan balances of $32.9 million and $27.2 million, respectively, to substandard, the majority of which is adequately secured by real estate collateral. Management cannot predict the extent to which economic conditions may worsen or other factors, which may impact borrowers and the potential problem loans. Accordingly, there can be no assurance that other loans will not become over 90 days past due, be placed on nonaccrual, become troubled loans modifications or require increased allowance coverage and provision for loan losses. To mitigate this risk the Company maintains a diversified loan portfolio, has no significant concentration in any particular industry and originates loans primarily within its footprint.
Deposits
Total deposits were $11.59 billion at September 30, 2024, up $619.3 million, or 5.6%, from December 31, 2023. As of September 30, 2024, there were $250.0 million of brokered time deposits, up from $155.2 million as of December 31, 2023. The increase in deposits was primarily due to higher consumer deposit balances and accounts and the inflow of seasonal municipal deposits. The Company continues to experience some incremental migration from noninterest bearing and low interest checking and savings accounts into higher cost money market and time deposit instruments. The Company’s composition of total deposits is diverse and granular with over 563,000 accounts with an average per account balance of $20,560 as of September 30, 2024. As of September 30, 2024 and December 31, 2023 the estimated amounts of uninsured deposits based on the methodologies and assumptions used for the bank regulatory reporting were $4.81 billion and $4.08 billion, respectively. Total average deposits increased $1.39 billion, or 14.1%, from the same period last year. The increase in average balances was primarily due to the $1.31 billion in deposits acquired from Salisbury in the third quarter of 2023.

Borrowed Funds
The Company’s borrowed funds consist of short-term borrowings and long-term debt. Short-term borrowings totaled $205.0 million at September 30, 2024 compared to $386.7 million at December 31, 2023. Long-term debt was $29.7 million at September 30, 2024 compared to $29.8 million at December 31, 2023.
For more information about the Company’s borrowing capacity and liquidity position, see “Liquidity Risk” below.
Subordinated Debt
On June 23, 2020, the Company issued $100.0 million of 5.00% fixed-to-floating rate subordinated notes due 2030. The subordinated notes, which qualify as Tier 2 capital, bear interest at an annual rate of 5.00%, payable semi-annually in arrears commencing on January 1, 2021, and a floating rate of interest equivalent to the three-month SOFR plus a spread of 4.85%, payable quarterly in arrears commencing on October 1, 2025. The subordinated debt issuance cost of $2.2 million is being amortized on a straight-line basis into interest expense over five years. The Company repurchased $2.0 million of the subordinated notes in 2022 at a discount of $0.1 million.
Subordinated notes assumed in connection with the Salisbury acquisition included $25.0 million of 3.50% fixed-to-floating rate subordinated notes due 2031. The subordinated notes, which qualify as Tier 2 capital, bear interest at an annual rate of 3.50%, payable quarterly in arrears commencing on June 30, 2021, and a floating rate of interest equivalent to the three-month SOFR plus a spread of 2.80%, payable quarterly in arrears commencing on June 30, 2026. As of the acquisition date, the fair value discount was $3.0 million, which will be amortized into interest expense over the expected call or maturity date.
As of September 30, 2024 and December 31, 2023 the subordinated debt net of unamortized issuance costs and fair value discount was $120.8 million and $119.7 million, respectively.
Capital Resources
Stockholders’ equity of $1.52 billion represented 11.00% of total assets at September 30, 2024 compared with $1.43 billion, or 10.71% of total assets, as of December 31, 2023. Stockholders’ equity increased $96.3 million from December 31, 2023 driven by net income generation of $104.6 million for the nine months ended September 30, 2024 and a decrease of $35.2 million in accumulated other comprehensive loss due primarily to the change in the fair value of securities available for sale, partially offset by dividends declared of $46.2 million.
The Company did not purchase shares of its common stock during the three months ended September 30, 2024. The Company purchased 7,600 shares of its common stock in the first and second quarters of 2024 at an average price of $33.02 per share under its previously announced share repurchase program. The Company may repurchase shares of its common stock from time to time to mitigate the potential dilutive effects of stock-based incentive plans and other potential uses of common stock for corporate purposes. As of September 30, 2024, there were 1,992,400 shares available for repurchase under this plan authorized on December 18, 2023, which is set to expire on December 31, 2025.
As the capital ratios in the following table indicate, the Company remained “well capitalized” at September 30, 2024 under applicable bank regulatory requirements. Capital measurements are well in excess of regulatory minimum guidelines and meet the requirements to be considered well capitalized for all periods presented. To be considered well capitalized, tier 1 leverage, common equity tier 1 capital, tier 1 capital and total risk-based capital ratios must be 5%, 6.5%, 8% and 10%, respectively.

In March 2020, the OCC, the Board of Governors of the Federal Reserve System and the FDIC announced an interim final rule to delay the estimated impact on regulatory capital stemming from the implementation of CECL. Under the modified CECL transition provision, the regulatory capital impact of the January 1, 2020 CECL adoption date adjustment to the allowance for credit losses (after-tax) has been deferred and will phase into regulatory capital at 25% per year commencing January 1, 2022. For the ongoing impact of CECL, the Company was allowed to defer the regulatory capital impact of the allowance for credit losses in an amount equal to 25% of the change in the allowance for credit losses (pre-tax) recognized through earnings for each period between January 1, 2020 and December 31, 2021. The cumulative adjustment to the allowance for credit losses between January 1, 2020 and December 31, 2021, will also phase into regulatory capital at 25% per year commencing January 1, 2022. The Company adopted the capital transition relief over the permissible five-year period.
Liquidity and Interest Rate Sensitivity Management
Market Risk
Interest rate risk is the most significant market risk affecting the Company. Other types of market risk, such as foreign currency exchange rate risk and commodity price risk, do not arise in the normal course of the Company’s business activities or are immaterial to the results of operations.
Interest rate risk is defined as an exposure to a movement in interest rates that could have an adverse effect on the Company’s net interest income. Net interest income is susceptible to interest rate risk to the degree that interest-bearing liabilities mature or reprice on a different basis than earning assets. When interest-bearing liabilities mature or reprice more quickly than earning assets in a given period, a significant increase in market rates of interest could adversely affect net interest income. Similarly, when earning assets mature or reprice more quickly than interest-bearing liabilities, falling interest rates could result in a decrease in net interest income.
To manage the Company’s exposure to changes in interest rates, management monitors the Company’s interest rate risk. Management’s Asset Liability Committee (“ALCO”) meets monthly to review the Company’s interest rate risk position and profitability and to recommend strategies for consideration by the Board of Directors (the “Board”). Management also reviews loan and deposit pricing and the Company’s securities portfolio, formulates investment and funding strategies and oversees the timing and implementation of transactions to assure attainment of the Board’s objectives in the most effective manner. Notwithstanding the Company’s interest rate risk management activities, the potential for changing interest rates is an uncertainty that can have an adverse effect on net income.
In managing the Company’s asset/liability position, the Board and management aim to manage the Company’s interest rate risk while minimizing net interest margin compression. At times, depending on the level of general interest rates, the relationship between long and short-term interest rates, market conditions and competitive factors, the Board and management may determine to increase the Company’s interest rate risk position somewhat in order to increase its net interest margin. The Company’s results of operations and net portfolio values remain vulnerable to changes in interest rates and fluctuations in the difference between long and short-term interest rates.
The primary tool utilized by the ALCO to manage interest rate risk is earnings at risk modeling (interest rate sensitivity analysis). Information, such as principal balance, interest rate, maturity date, cash flows, next repricing date (if needed) and current rates are uploaded into the model to create an ending balance sheet. In addition, the ALCO makes certain assumptions regarding prepayment speeds for loans and mortgage related investment securities along with any optionality within the deposits and borrowings. The model is first run under an assumption of a flat rate scenario (i.e. no change in current interest rates) with a static balance sheet. Four additional models are run in which a gradual increase of 200 bps, a gradual increase of 100 bps, a gradual decrease of 100 bps and a gradual decrease of 200 bps takes place over a 12-month period with a static balance sheet. Under these scenarios, assets subject to prepayments are adjusted to account for faster or slower prepayment assumptions. Any investment securities or borrowings that have callable options embedded in them are handled accordingly based on the interest rate scenario. The resulting changes in net interest income are then measured against the flat rate scenario. The Company also runs other interest rate scenarios to highlight potential interest rate risk.

The Company’s Interest Rate Sensitivity has remained in a near neutral position. In the declining rate scenario, net interest income is projected to modestly decrease when compared to the forecasted net interest income in the flat rate scenario through the simulation period. The decrease in net interest income is a result of earning assets repricing and rolling over at lower yields at a faster pace than interest-bearing liabilities decline and/or reach their floors. In the rising rate scenarios, net interest income is near neutral, impacted by slowing prepayments speeds and increased deposit reactivity; the magnitude of potential impact on earnings may be affected by the ability to lag deposit repricing on NOW, savings, money market deposit accounts and time accounts. Net interest income for the next twelve months in the +200/+100/-100/-200 bp scenarios, as described above, is within the internal policy risk limits of not more than a 7.5% reduction in net interest income. The following table summarizes the percentage change in net interest income in the rising and declining rate scenarios over a 12-month period from the forecasted net interest income in the flat rate scenario using the September 30, 2024 balance sheet position:

Interest Rate Sensitivity Analysis |
Change in interest rates | Percent change in
(in bps) | net interest income
+200 | 0.05%
+100 | 0.35%
-100 | (0.41)%
-200 | (0.44%)

The Company anticipates that the trajectory of net interest income will continue to depend significantly on the timing and path of short to mid-term interest rates which are heavily driven by inflationary pressures and FOMC monetary policy. In response to the economic impact of the pandemic, the federal funds rate was reduced to near zero in March 2020, term interest rates fell sharply across the yield curve and the Company reduced deposit rates. Post-pandemic, inflationary pressures have resulted in a higher overall yield curve with Federal Funds increases of 425 bps in 2022 with an additional 100 bps of increases in 2023. However, the tightening cycle ended in September of 2024 with the Federal Reserve lowering the federal funds rate by 50 bps. While deposit rates increased meaningfully in 2023 and have continued to increase in early 2024 in conjunction with elevated short-term interest rates, the recent federal funds rate reduction has provided the catalyst for the Company to begin reducing deposit rates. The Company continues to focus on managing deposit expense in an environment of still elevated but declining short-term interest rates while allowing assets to reprice upward in relation to existing portfolio asset yields.
Liquidity Risk
Liquidity risk arises from the possibility that the Company may not be able to satisfy current or future financial commitments or may become unduly reliant on alternate funding sources. The objective of liquidity management is to ensure the Company can fund balance sheet growth, meet the cash flow requirements of depositors wanting to withdraw funds or borrowers needing assurance that sufficient funds will be available to meet their credit needs. ALCO is responsible for liquidity management and has developed guidelines, which cover all assets and liabilities, as well as off-balance sheet items that are potential sources or uses of liquidity. Liquidity policies must also provide the flexibility to implement appropriate strategies, along with regular monitoring of liquidity and testing of the contingent liquidity plan. Requirements change as loans grow, deposits and securities mature and payments on borrowings are made. Liquidity management includes a focus on interest rate sensitivity management with a goal of avoiding widely fluctuating net interest margins through periods of changing economic conditions. Loan repayments and maturing investment securities are a relatively predictable source of funds. However, deposit flows, calls of investment securities and prepayments of loans and mortgage-related securities are strongly influenced by interest rates, the housing market, general and local economic conditions, and competition in the marketplace. Management continually monitors marketplace trends to identify patterns that might improve the predictability of the timing of deposit flows or asset prepayments.
The primary liquidity measurement the Company utilizes is called “Basic Surplus,” which captures the adequacy of its access to reliable sources of cash relative to the stability of its funding mix of average liabilities. This approach recognizes the importance of balancing levels of cash flow liquidity from short and long-term securities with the availability of dependable borrowing sources, which can be accessed when necessary. At September 30, 2024, the Company’s Basic Surplus measurement was 16.4% of total assets, or $2.26 billion, as compared to the December 31, 2023 Basic Surplus of 11.6%, or $1.54 billion, and was above the Company’s minimum of 5% (calculated at $692.0 million and $665.5 million of period end total assets as September 30, 2024 and December 31, 2023, respectively) set forth in its liquidity policies.

At September 30, 2024 and December 31, 2023, FHLB advances outstanding totaled $129.6 million and $322.7 million, respectively. At September 30, 2024 and December 31, 2023, the Bank had $194.0 million and $77.0 million, respectively, of collateral encumbered by municipal letters of credit. The Bank is a member of the FHLB system and had additional borrowing capacity from the FHLB of approximately $1.63 billion at September 30, 2024 and $1.11 billion at December 31, 2023. In addition, unpledged securities could have been used to increase borrowing capacity at the FHLB by an additional $807.7 million and $823.3 million at September 30, 2024 and December 31, 2023, respectively, or used to collateralize other borrowings, such as repurchase agreements. The Company also has the ability to issue brokered time deposits and to borrow against established borrowing facilities with other banks (federal funds), which could provide additional liquidity of $2.06 billion at September 30, 2024 and $2.01 billion at December 31, 2023. In addition, the Bank has a “Borrower-in-Custody” program with the FRB with the addition of the ability to pledge automobile and residential solar loans as collateral. At September 30, 2024 and December 31, 2023, the Bank had the capacity to borrow $1.12 billion and $1.02 billion, respectively, from this program. The Company’s internal policy authorizes borrowing up to 25% of assets. Under this policy, remaining available borrowing capacity totaled $3.41 billion at September 30, 2024 and $2.99 billion at December 31, 2023.
This Basic Surplus approach enables the Company to appropriately manage liquidity from both operational and contingency perspectives. By tempering the need for cash flow liquidity with reliable borrowing facilities, the Company is able to operate with a more fully invested and, therefore, higher interest income generating securities portfolio. The makeup and term structure of the securities portfolio is, in part, impacted by the overall interest rate sensitivity of the balance sheet. Investment decisions and deposit pricing strategies are impacted by the liquidity position. The Company considers its Basic Surplus position to be strong. However, certain events may adversely impact the Company’s liquidity position in 2024. While short-term interest rates have declined, they remain elevated related to recent history, which could result in deposit declines as depositors have alternative opportunities for yield on their excess funds. In the current economic environment, draws against lines of credit could drive asset growth higher. Disruptions in wholesale funding markets could spark increased competition for deposits. These scenarios could lead to a decrease in the Company’s Basic Surplus measure below the minimum policy level of 5%. Note, enhanced liquidity monitoring was put in place to quickly respond to the changing environment during the pandemic including increasing the frequency of monitoring and adding additional sources of liquidity. While the pandemic has come to an end, this enhanced monitoring continues as elevated interest rates and the recent bank failures have led to a deposit decline in the banking system and increased volatility to liquidity risk.
At September 30, 2024, a portion of the Company’s loans and securities were pledged as collateral on borrowings. Therefore, once on-balance sheet liquidity is reduced, future growth of earning assets will depend upon the Company’s ability to obtain additional funding, through growth of core deposits and collateral management and may require further use of brokered time deposits or other higher cost borrowing arrangements.
The Company’s primary source of funds is dividends from its subsidiaries. Various laws and regulations restrict the ability of banks to pay dividends to their stockholders. Generally, the payment of dividends by the Company in the future as well as the payment of interest on the capital securities will require the generation of sufficient future earnings by its subsidiaries.
Certain restrictions exist regarding the ability of the Bank to transfer funds to the Company in the form of cash dividends. The approval of the OCC is required to pay dividends when a bank fails to meet certain minimum regulatory capital standards or when such dividends are in excess of a subsidiary bank’s earnings retained in the current year plus retained net profits for the preceding two years as specified in applicable OCC regulations. At September 30, 2024, approximately $95.8 million of the total stockholders’ equity of the Bank was available for payment of dividends to the Company without approval by the OCC. The Bank’s ability to pay dividends is also subject to the Bank being in compliance with regulatory capital requirements. The Bank is currently in compliance with these requirements. Under the State of Delaware General Corporation Law, the Company may declare and pay dividends either out of accumulated net retained earnings or capital surplus.

ITEM 1A. | RISK FACTORS

Except as set for below, there are no material changes to the risk factors as previously discussed in Part I, Item 1A. of our 2023 Annual Report on Form 10-K.
Risks Related to the Merger
The Merger is subject to a number of conditions, including the receipt of waivers and/or approvals from governmental authorities, that may delay the Merger or adversely impact the Company’s and Evans’s ability to complete the Merger.
The completion of the Merger is subject to the satisfaction or waiver of a number of conditions. Before the Merger may be completed, certain approvals, waivers or consents must be obtained from federal governmental authorities, including the Federal Reserve Bank of New York and the OCC. Satisfying the requirements of these governmental authorities may delay the date of completion of the Merger. In addition, these governmental authorities may include conditions on the completion of the Merger or require changes to the terms of the Merger. While it is currently anticipated that the Merger will be completed promptly following the receipt of all required regulatory and shareholder approvals, there can be no assurance that the conditions to closing will be satisfied in a timely manner or at all, or that an effect, event, development or change will not transpire that could delay or prevent these conditions from being satisfied or impose additional costs on or limit the revenues of the Company following the Merger, any of which might have a material adverse effect on the Company following the Merger. The parties are not obligated to complete the Merger should any regulatory approval contain a condition, restriction or requirement that our Board of Directors reasonably determines in good faith would, individually or in the aggregate, materially reduce the benefits of the Merger to such a degree that the Company would not have entered into the Merger Agreement had such condition, restriction or requirement been known at the date of the Merger Agreement.
The Company and Evans cannot provide any assurances with respect to the timing of the closing of the Merger, whether the Merger will be completed at all or when Evans shareholders would receive the consideration for the Merger, if at all.

The market price of the Company’s common stock may decline as a result of the Merger and the market price of the Company’s common stock after the consummation of the Merger may be affected by factors different from those affecting the price of the Company’s common stock before the Merger.
The market price of the Company’s common stock may decline as a result of the Merger if the Company does not achieve the perceived benefits of the Merger or the effect of the Merger on the Company’s financial results is not consistent with the expectations of financial or industry analysts.
In addition, the consummation of the Merger will result in the combination of two companies that currently operate as independent companies. The business of the Company and the business of Evans differ. As a result, while the Company expects to benefit from certain synergies following the Merger, the Company may also encounter new risks and liabilities associated with these differences. Following the Merger, shareholders of the Company and Evans will own interests in a combined company operating an expanded business and may not wish to continue to invest in the Company, or for other reasons may wish to dispose of some or all of the Company’s common stock. If, following the effective time of the Merger, large amounts of the Company’s common stock are sold, the price of the Company’s common stock could decline.
Further, the results of operations of the Company and the market price of the Company’s common stock after the Merger may be affected by factors different from those currently affecting the independent results of operations of each of the Company and Evans and the market price of the Company’s common stock. Accordingly, the Company’s historical market prices and financial results may not be indicative of these matters for the Company after the Merger.
The Merger Agreement may be terminated in accordance with its terms and the Merger may not be completed.
The Company and Evans can mutually agree to terminate the Merger Agreement at any time before the Merger has been completed, and either company can terminate the Merger Agreement if:

| ● | any regulatory approval required for consummation of the Merger and the other transactions contemplated by the Merger Agreement has been denied by final, nonappealable action of any regulatory authority, or an application for regulatory approval has been permanently withdrawn at the request of a governmental authority;

| ● | the required approval of the Merger Agreement by the Evans shareholders is not obtained;

| ● | the other party materially breaches any of its representations, warranties, covenants or other agreements set forth in the Merger Agreement (provided that the terminating party is not then in material breach of any representation, warranty, covenant or other agreement contained in the Merger Agreement), which breach is not cured within 30 days of written notice of the breach, or by its nature cannot be cured prior to the closing of the Merger, and such breach would entitle the non-breaching party not to consummate the Merger; or

| ● | the Merger is not consummated by September 15, 2025, unless the failure to consummate the Merger by such date is due to a material breach of the Merger Agreement by the terminating party.

In addition, the Company may terminate the Merger Agreement if:

Failure to complete the merger could negatively impact the stock price of the Company and its future business and financial results.
Completion of the Merger is subject to the satisfaction or waiver of a number of conditions, including approval by Evans shareholders of the Merger. The Company cannot guarantee when or if these conditions will be satisfied or that the Merger will be successfully completed. The consummation of the Merger may be delayed, the Merger may be consummated on terms different than those contemplated by the Merger Agreement, or the Merger may not be consummated at all. If the Merger is not completed, the ongoing business of the Company may be adversely affected, and the Company will be subject to several risks, including the following:

| ● | the Company could incur substantial costs relating to the proposed Merger, such as legal, accounting, financial advisor, filing, printing and mailing fees; and

| ● | the Company’s management’s and employees’ attention may be diverted from their day-to-day business and operational matters as a result of efforts relating to the attempt to consummate the Merger.

In addition, if the Merger is not completed, the Company may experience negative reactions from the financial markets and from its customers and employees. The Company also could be subject to litigation related to any failure to complete the merger or to enforcement proceedings commenced against the Company to perform its obligations under the Merger Agreement. If the Merger is not completed, the Company cannot assure its stockholders that the risks described above will not materialize and will not materially affect the Company’s business and financial results or the stock price of the Company.
The integration of the Company and Evans will present significant challenges and expenses that may result in the combined business not operating as effectively as expected, or in the failure to achieve some or all of the anticipated benefits of the transaction.
The benefits and synergies expected to result from the proposed Merger will depend in part on whether the operations of Evans can be integrated in a timely and efficient manner with those of the Company. The Company will face challenges and costs in consolidating its functions with those of Evans, and integrating the organizations, procedures and operations of the two businesses. The integration of the Company and Evans will be complex and time-consuming, and the management of both companies will have to dedicate substantial time and resources to it. These efforts could divert management’s focus and resources from serving existing customers or other strategic opportunities and from day-to-day operational matters during the integration process. Failure to successfully integrate the operations of the Company and Evans could result in the failure to achieve some of the anticipated benefits from the transaction, including cost savings and other operating efficiencies, and the Company may not be able to capitalize on the existing relationships of Evans to the extent anticipated, or it may take longer, or be more difficult or expensive than expected to achieve these goals. This could have an adverse effect on the business, results of operations, financial condition or prospects of the Company and/or the Bank after the transaction.
Unanticipated costs relating to the merger could reduce the Company’s future earnings per share.
The Company BT has incurred substantial legal, accounting, financial advisory and other Merger-related costs, and management has devoted considerable time and effort in connection with the Merger. If the Merger is not completed, the Company will bear certain fees and expenses associated with the Merger without realizing the benefits of the Merger. If the Merger is completed, the Company expects to incur substantial expenses in connection with integrating the business, operations, network, systems, technologies, policies and procedures of the two companies. The fees and expenses may be significant and could have an adverse impact on the Company’s results of operations.
The Company believes that it has reasonably estimated the likely costs of integrating the operations of the Company and Evans, and the incremental costs of operating as a combined company. However, it is possible that unexpected transaction costs such as taxes, fees or professional expenses or unexpected future operating expenses such as increased personnel costs or increased taxes, as well as other types of unanticipated adverse developments, could have a material adverse effect on the results of operations and financial condition of the combined company. If unexpected costs are incurred, the Merger could have a dilutive effect on the Company’s earnings per share. In other words, if the Merger is completed, the earnings per share of the Company’s common stock could be less than anticipated or even less than if the Merger had not been completed.
Estimates as to the future value of the combined company are inherently uncertain.
Any estimates as to the future value of the combined company, including estimates regarding the earnings per share of the combined company, are inherently uncertain. The future value of the combined company will depend upon, among other factors, the combined company’s ability to achieve projected revenue and earnings expectations and to realize the anticipated synergies, all of which are subject to the risks and uncertainties described in these risk factors.

Following the Merger, the Company’s stockholders may not receive dividends at the same rate that they did as stockholders of the Company prior to the Merger for various reasons, including the following:
