1. BASIS OF INTERIM PRESENTATION AND STATUS OF RECENT ACCOUNTING PRONOUNCEMENTS

The consolidated financial statements include the accounts of Citizens & Northern Corporation and its subsidiaries, Citizens & Northern Bank (“C&N Bank”), Bucktail Life Insurance Company and Citizens & Northern Investment Corporation (collectively, “Corporation”). The consolidated financial statements also include C&N Bank’s wholly-owned subsidiaries, C&N Financial Services, LLC and Northern Tier Holding LLC. C&N Bank is the sole member of C&N Financial Services, LLC and Northern Tier Holding LLC. All material intercompany balances and transactions have been eliminated in consolidation.

The consolidated financial information included herein, except the consolidated balance sheet dated December 31, 2023, is unaudited. Such information reflects all adjustments (consisting solely of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the financial position, results of operations, comprehensive income, cash flows and changes in stockholders’ equity for the interim periods; however, the information does not include all disclosures required by accounting principles generally accepted in the United States of America (“U.S. GAAP”) for a complete set of financial statements.

Operating results reported for the three-month period ended March 31, 2024 might not be indicative of the results for the year ending December 31, 2024. The Corporation evaluates subsequent events through the date of filing with the Securities and Exchange Commission.

RECENT ACCOUNTING PRONOUNCEMENTS

The Financial Accounting Standards Board (FASB) issues Accounting Standard Updates (ASUs) to communicate changes to the FASB Accounting Standard Codification (ASC). This section provides a summary description of recent ASUs that have significant implications (elected or required) within the consolidated financial statements, or that management expects may have a significant impact on financial statements issued in the foreseeable future.

CECL ADOPTION

On January 1, 2023, the Corporation adopted ASU 2016-13 Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASC 326). This standard replaced the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (“CECL”) methodology. The Corporation adopted ASC 326 using the modified retrospective approach for all financial assets measured at amortized cost and off-balance sheet credit exposures. The following table illustrates the impact on the allowance for credit losses from the adoption of ASC 326:

​

Recent Issued but Not Yet Effective Accounting Pronouncements

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures which improves the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. ASU No. 2023-09 is effective for public business entities

for annual periods beginning after December 15, 2024. The ASU may be adopted on a prospective or retrospective basis and early adoption is permitted. The Corporation is currently evaluating the impact the new guidance will have on disclosures related to income taxes.

2. PER SHARE DATA

Basic earnings per common share are calculated using the two-class method to determine income attributable to common shareholders. Unvested restricted stock awards that contain nonforfeitable rights to dividends are considered participating securities under the two-class method. Distributed dividends and an allocation of undistributed net income to participating securities reduce the amount of income attributable to common shareholders. Income attributable to common shareholders is then divided by weighted-average common shares outstanding for the period to determine basic earnings per common share.

Diluted earnings per common share are calculated under the more dilutive of either the treasury method or the two-class method. Diluted earnings per common share is computed using weighted-average common shares outstanding, plus weighted-average common shares available from the exercise of all dilutive stock options, less the number of shares that could be repurchased with the proceeds of stock option exercises based on the average share price of the Corporation’s common stock during the period.

(a) | Basic and diluted earnings per share under the two-class method are determined on net income reported on the consolidated statements of income, less earnings allocated to non-vested restricted shares with nonforfeitable dividends (participating securities).

Anti-dilutive stock options are excluded from earnings per share calculations. There were no anti-dilutive instruments outstanding in the three-month periods ended March 31, 2024 and 2023.

The Corporation’s mortgage-backed securities and collateralized mortgage obligations have stated maturities that may differ from actual maturities due to borrowers’ ability to prepay obligations. Cash flows from such investments are dependent upon the performance of the underlying mortgage loans and are generally influenced by the level of interest rates. In the table above, mortgage-backed securities and collateralized mortgage obligations are shown in one period.

CITIZENS & NORTHERN CORPORATION – FORM 10-Q

Investment securities carried at $183,661,000 at March 31, 2024 and $232,437,000 at December 31, 2023 were pledged as collateral for public deposits, trusts and certain other deposits as provided by law. See Note 8 for information concerning securities pledged to secure borrowing arrangements and Note 11 for information related to securities pledged against interest rate swap obligations.

A summary of information management considered in evaluating debt and equity securities for credit losses at March 31, 2024 and December 31, 2023 is provided below.

Debt Securities

As reflected in the table above, gross unrealized holding losses on available-for-sale debt securities totaled $52,272,000 at March 31, 2024 and $49,564,000 at December 31, 2023. At March 31, 2024, the Corporation does not have the intent to sell, nor is it more likely than not it will be required to sell, these securities before it is able to recover the amortized cost basis. The unrealized holding losses were consistent with significant increases in market interest rates that have occurred subsequent to the purchase of most of the securities.

At March 31, 2024 and December 31, 2023, management performed an assessment for possible credit losses of the Corporation’s debt securities on an issue-by-issue basis, relying on information obtained from various sources, including publicly available financial data, ratings by external agencies, brokers and other sources. At March 31, 2024 and December 31, 2023, all of the Corporation’s holdings of bank holding company debt securities, obligations of states and political subdivisions and private label commercial mortgage-backed securities were investment grade and there have been no payment defaults.

Based on the results of the assessment, there was no allowance for credit losses (“ACL”) required on available-for-sale debt securities in an unrealized loss position at March 31, 2024 and December 31, 2023.

The Corporation evaluated its holding of FHLB-Pittsburgh stock for impairment and deemed the stock to not be impaired at March 31, 2024 and December 31, 2023. In making this determination, management concluded that recovery of total outstanding par value, which equals the carrying value, is expected. The decision was based on review of financial information that FHLB-Pittsburgh has made publicly available.

The Corporation grants loans to individuals as well as commercial and tax-exempt entities. Commercial, residential and personal loans are made to customers geographically concentrated in Northcentral Pennsylvania, the Southern tier of New York State, Southeastern Pennsylvania and Southcentral Pennsylvania. Although the Corporation has a diversified loan portfolio, a significant portion of its debtors’ ability to honor their contracts is dependent on the local economic conditions within the region.

Acquired loans were initially recorded at fair value, with adjustments made to gross amortized cost based on movements in interest rates (market rate adjustment) and based on credit fair value adjustments on non-impaired loans and impaired loans. Subsequently, the Corporation has recognized amortization and accretion of a portion of the market rate adjustments and credit adjustments on performing loans. For the three-month periods ended March 31, 2024 and 2023, adjustments to the initial market rate and credit fair value adjustments of performing loans were recognized as follows:

The Corporation uses an internal risk rating system. Under the risk rating system, the Corporation classifies problem or potential problem loans as “Special Mention,” “Substandard,” or “Doubtful” on the basis of currently existing facts, conditions and values. Loans that do not currently expose the Corporation to sufficient risk to warrant classification as Substandard or Doubtful, but possess weaknesses that deserve management’s close attention, are deemed to be Special Mention. Substandard loans include those characterized by the distinct possibility that the Corporation will sustain some loss if the deficiencies are not corrected. Loans classified as Doubtful have all the weaknesses inherent in those classified as Substandard with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. Risk ratings are updated any time that conditions or the situation warrants. Loans not classified are included in the “Pass” rows in the table that follows.

The Corporation has certain loans for which repayment is dependent upon the operation or sale of collateral, as the borrower is experiencing financial difficulty. The underlying collateral can vary based upon the type of loan. The following provides more detail about the types of collateral that secure collateral dependent loans:

| ● | Commercial real estate loans can be secured by either owner occupied commercial real estate or non-owner occupied investment commercial real estate. Typically, owner occupied commercial real estate loans are secured by office buildings, warehouses, manufacturing facilities and other commercial and industrial properties occupied by operating companies. Non-owner occupied commercial real estate loans are generally secured by office buildings and complexes, retail facilities, multifamily complexes, land under development, industrial properties, as well as other commercial or industrial real estate.

| ● | All other commercial loans include loans typically secured by business assets including inventory, equipment and receivables. Also within this category, commercial construction and land loans and some commercial lines of credit are secured by real estate.

| ● | Residential mortgage loans are typically secured by first mortgages, and in some cases could be secured by a second mortgage.

| ● | Consumer loans are generally secured by automobiles, motorcycles, recreational vehicles and other personal property. Some consumer loans are unsecured and have no underlying collateral.

Modifications Made to Borrowers Experiencing Financial Difficulty

​

The Corporation closely monitors the performance of the loans that are modified to borrowers experiencing financial difficulty to understand the effectiveness of its modification efforts. Because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses because of the measurement methodologies used to estimate the allowance, a change to the allowance for credit losses is generally not recorded upon modification. During the three months ended March 31, 2024 and March 31, 2023, the Corporation had no modifications to borrowers experiencing financial difficulty.

​

The Corporation closely monitors the performance of the loans modified to borrowers experiencing financial difficultly to understand the effectiveness of its modification efforts. The following table depicts the performance of two loans which were in non-accrual status at March 31, 2024 that were modified in the past twelve months:

​

The Corporation maintains an allowance for off-balance sheet credit exposures such as unfunded balances for existing lines of credit, commitments to extend future credit, commercial letters of credit and credit enhancement obligations related to residential mortgage loans sold with recourse, when there is a contractual obligation to extend credit and when this extension of credit is not unconditionally cancellable (i.e. commitment cannot be canceled at any time). The allowance for off-balance sheet credit exposures is adjusted as a provision for credit loss expense. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over their estimated lives. The allowance for credit losses for off-balance sheet exposures of $684,000 at March 31, 2024 and $690,000 at December 31, 2023, is included in accrued interest and other liabilities on the unaudited consolidated balance sheets.

The Subordinated Notes mature on June 1, 2031 and bear interest at a fixed annual rate of 3.25%, to June 1, 2026. From June 1, 2026 to maturity or early redemption, the interest rate will reset quarterly to an interest rate per annum equal to the three-month Secured Overnight Financing Rate provided by the Federal Reserve Bank of New York plus 259 basis points. The Corporation is entitled to redeem the Subordinated Notes, in whole or in part, at any time on or after June 1, 2026, and to redeem the Subordinated Notes at any time in whole upon certain other events. Any redemption of the Subordinated Notes will be subject to prior regulatory approval to the extent required.

The Subordinated Notes are not subject to redemption at the option of the holders. The Subordinated Notes are unsecured, subordinated obligations of the Corporation only and are not obligations of, and are not guaranteed by, any subsidiary of the Corporation. The Subordinated Notes rank junior in right to payment to the Corporation's current and future senior indebtedness, including the Senior Notes (described above). The Subordinated Notes are intended to qualify as Tier 2 capital for regulatory capital purposes.

The Subordinated Notes were recorded, net of debt issuance costs of $563,000, at an initial carrying amount of $24,437,000. Debt issuance costs are amortized through June 1, 2026 as an adjustment of the effective interest rate. Amortization of debt issuance costs associated with the Subordinated Notes totaling $28,000 in the first quarter 2024 and $27,000 in the first quarter 2023, was included in interest expense in the unaudited consolidated statements of income.

At March 31, 2024 and December 31, 2023, the carrying amounts of subordinated debt agreements are as follows:

9. STOCK-BASED COMPENSATION PLANS

The Corporation has a stock incentive plan for selected officers and the independent directors. The first quarter 2024 awards to employees vest ratably over three years, and the 2024 restricted stock awards for the independent directors vest over one year. Following is a summary of restricted stock awards granted in the three-month period ended March 31, 2024:

​

​ | ​ | ​ | ​ | ​ | ​
(Dollars in Thousands) |  | ​ |  | Aggregate
​ | ​ | ​ | ​ | Grant
​ | ​ | ​ | ​ | Date
​ | ​ | Number of | ​ | Fair
​ | ​ | Shares | ​ | Value
1st quarter 2024 awards: | ​ | ​ | ​ | ​ | ​
Time-based awards to independent directors | ​ | 10,000 | ​ | $ | 214
Time-based awards to employees | ​ | 43,514 | ​ | ​ | 931
Performance-based awards to employees | ​ | 19,346 | ​ | ​ | 371
Total | ​ | 72,860 | ​ | $ | 1,516

​

Compensation cost related to restricted stock is recognized based on the fair value of the stock at the grant date over the vesting period, adjusted for estimated and actual forfeitures. Total annual stock-based compensation for the year ending December 31, 2024 is estimated to total $1,300,000. Total stock-based compensation expense attributable to restricted stock awards amounted to $326,000 in the first quarter 2024 and $377,000 in the first quarter 2023.

10. CONTINGENCIES

Class Action Litigation

On March 27, 2024, a putative class action lawsuit was filed in the US District Court for the Western District of Texas by investors in a purported Ponzi scheme operated by two individuals, one of whom maintained accounts at C&N Bank. The plaintiffs have sued C&N Bank, along with another bank, and additional law firm and accounting firm defendants. The case is styled Goldovsky, et al. v. Rausch, et al. Plaintiffs have asserted claims against C&N Bank and the other bank for aiding and abetting alleged violations of the Texas Securities Act, and additional claims against the legal and accounting professionals for statutory fraud, common law fraud, negligent misrepresentation, and knowing participation in breach of fiduciary duty. C&N Bank has not yet responded to the complaint. C&N Bank believes that it has substantial defenses, and it intends to defend itself against the plaintiffs’ allegations. The Corporation does not

believe at this time that a loss is probable in this matter, nor can a range of possible losses be determined. Accordingly, no accrual or range of loss has been included in the accompanying financial statements.

Other Matters

In the normal course of business, the Corporation is subject to pending and threatened litigation in which claims for monetary damages are asserted. In management’s opinion, the Corporation’s financial position and results of operations would not be materially affected by the outcome of these legal proceedings.

​

11. DERIVATIVE FINANCIAL INSTRUMENTS

The Corporation is a party to derivative financial instruments. These financial instruments consist of interest rate swap agreements and risk participation agreements (RPAs) which contain master netting and collateral provisions designed to protect the party at risk.

Interest rate swaps with commercial loan banking customers were executed to facilitate their respective risk management strategies. Under the terms of these arrangements, the commercial banking customers effectively exchanged their floating interest rate exposures on loans into fixed interest rate exposures. Those interest rate swaps have been simultaneously economically hedged by offsetting interest rate swaps with a third party, such that the Corporation has effectively exchanged its fixed interest rate exposures for floating rate exposures. These derivatives are not designated as hedges and are not speculative. Rather, these derivatives result from a service provided to certain customers. As the interest rate swaps associated with this program do not meet the hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings.

The aggregate notional amount of interest rate swaps was $148,838,000 at March 31, 2024 and $150,028,000 at December 31, 2023. There were no interest rate swaps originated in the periods ended March 31, 2024, and 2023. There were no gross amounts of interest rate swap-related assets and liabilities not offset in the consolidated balance sheets at March 31, 2024. The net impact on the consolidated statements of income from interest rate swaps was an increase in interest income on loans of $498,000 in the first quarter 2024 and $345,000 in the first quarter 2023.

The Corporation has entered into an RPA with another institution as a means to assume a portion of the credit risk associated with a loan structure which includes a derivative instrument, in exchange for fee income commensurate with the risk assumed. This type of derivative is referred to as an “RPA In.” In addition, in an effort to reduce the credit risk associated with an interest rate swap agreement with a borrower for whom the Corporation has provided a loan structured with a derivative, the Corporation purchased an RPA from an institution participating in the facility in exchange for a fee commensurate with the risk shared. This type of derivative is referred to as an “RPA Out.” The net impact on the consolidated statements of income from RPAs was an increase in other noninterest income of $1,000 in the first quarter 2024 and $16,000 in the first quarter 2023.

The table below presents the fair value of the Corporation’s derivative financial instruments as well as their classification on the consolidated balance sheets at March 31, 2024 and December 31, 2023:

The Corporation’s agreements with its derivative counterparties provide that if the Corporation defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Corporation could also be declared in default on its derivative obligations. Further, if the Corporation were to fail to maintain its status as a well or adequately capitalized institution, then the counterparties could terminate the derivative positions and the Corporation would be required to settle its obligations under the agreements. There was interest-bearing cash pledged as collateral against the Corporation’s liability related to the interest rate swaps of $1,140,000 at March 31, 2024 and $1,360,000 at December 31, 2023.

12. FAIR VALUE MEASUREMENTS AND FAIR VALUES OF FINANCIAL INSTRUMENTS

The Corporation measures certain assets and liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. FASB Topic 820, “Fair Value Measurements and Disclosures” establishes a framework for measuring fair value that includes a hierarchy used to classify the inputs used in measuring fair value. The hierarchy prioritizes the inputs used in determining valuations into three levels. The level in the fair value hierarchy within which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement. The levels of the fair value hierarchy are as follows:

Level 1 – Fair value is based on unadjusted quoted prices in active markets that are accessible to the Corporation for identical assets or liabilities. These generally provide the most reliable evidence and are used to measure fair value whenever available.

Level 2 – Fair value is based on significant inputs, other than Level 1 inputs, that are observable either directly or indirectly for substantially the full term of the asset or liability through corroboration with observable market data. Level 2 inputs include quoted market prices in active markets for similar assets or liabilities, quoted market prices in markets that are not active for identical or similar assets or liabilities and other observable inputs.

Level 3 – Fair value is based on significant unobservable inputs. Examples of valuation methodologies that would result in Level 3 classification include option pricing models, discounted cash flows and other similar techniques.

The Corporation monitors and evaluates available data relating to fair value measurements on an ongoing basis and recognizes transfers among the levels of the fair value hierarchy as of the date of an event or change in circumstances that affects the valuation method chosen. Examples of such changes may include the market for a particular asset or liability becoming active or inactive, changes in the availability of quoted prices, or changes in the availability of other market data.

Management’s evaluation and selection of valuation techniques and the unobservable inputs used in determining the fair values of assets valued using Level 3 methodologies include sensitive assumptions. Other market participants might use substantially different assumptions, which could result in calculations of fair values that would be substantially different than the amount calculated by management.

​

The fair value of servicing rights is affected by expected future interest rates. Increases (decreases) in future expected interest rates tend to increase (decrease) the fair value of the Corporation’s servicing rights because of changes in expected prepayment behavior by the borrowers on the underlying loans. Unrealized gains (losses) in fair value of servicing rights are included in Loan servicing fees, net, in the unaudited consolidated statements of income.

Loans are individually evaluated for credit loss when they do not share similar risk characteristics as similar loans within its loan pool. Foreclosed assets held for sale consist of real estate acquired by foreclosure. For individually evaluated loans secured by real estate and foreclosed assets held for sale, estimated fair values are determined primarily using values from third-party appraisals. Appraised values are discounted to arrive at the estimated selling price of the collateral, which is considered to be the estimated fair value. The discounts also include estimated costs to sell the property.

Certain of the Corporation’s financial instruments are not measured at fair value in the consolidated financial statements. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. Certain financial instruments and all nonfinancial instruments are excluded from disclosure requirements. Therefore, the aggregate fair value amounts presented may not represent the underlying fair value of the Corporation.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Certain statements in this section and elsewhere in this quarterly report on Form 10-Q are forward-looking statements. Citizens & Northern Corporation and its wholly-owned subsidiaries (collectively, the Corporation) intend such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Reform Act of 1995. Forward-looking statements, which are not historical facts, are based on certain assumptions and describe future plans, business objectives and expectations, and are generally identifiable by the use of words such as, "should", “likely”, "expect", “plan”, "anticipate", “target”, “forecast”, and “goal”. These forward-looking statements are subject to risks and uncertainties that are difficult to predict, may be beyond management’s control and could cause results to differ materially from those expressed or implied by such forward-looking statements. Factors which could have a material, adverse impact on the operations and future prospects of the Corporation include, but are not limited to, the following:

● | changes in monetary and fiscal policies of the Federal Reserve Board and the U.S. Government, particularly related to changes in interest rates

●changes in general economic conditions

● | adverse developments in the banking industry highlighted by high-profile bank failures and the potential impact of such developments on customer confidence, sources of liquidity and capital funding, and regulatory responses to these developments

●the Corporation’s credit standards and its on-going credit assessment processes might not protect it from significant credit losses
●legislative or regulatory changes
●downturn in demand for loan, deposit and other financial services in the Corporation’s market area
●increased competition from other banks and non-bank providers of financial services

● | technological changes and increased technology-related costs

● | information security breach or other technology difficulties or failures

●changes in accounting principles, or the application of generally accepted accounting principles

● | failure to achieve merger-related synergies and difficulties in integrating the business and operations of acquired institutions

● | fraud and cyber malfunction risks as usage of artificial intelligence continues to expand

​

These risks and uncertainties should be considered in evaluating forward-looking statements and undue reliance should not be placed on such statements.

EARNINGS OVERVIEW

First Quarter 2024 as Compared to First Quarter 2023

First quarter 2024 net income was $5,306,000, or $0.35 per diluted share, as compared to $6,253,000, or $0.40 per diluted share, in the first quarter 2023. Significant variances were as follows:

​

| ● | Net interest income of $19,041,000 in the first quarter 2024 was $1,740,000 lower than the first quarter 2023 total reflecting an increase in interest expense of $5,937,000 and an increase of $4,197,000 in interest and dividend income. The interest rate spread decreased 0.68%, as the average rate on interest-bearing liabilities increased 1.24%, while the average yield on earning assets increased 0.56%. The net interest margin was 3.29% in the first quarter 2024, down from 3.71% in the first quarter 2023.

​

| ● | For the quarter ended March 31, 2024, there was a provision for credit losses of $954,000, an increase of $1,306,000 in expense compared to a credit for credit losses (reduction in expense) of $352,000 in the first quarter 2023. The provision for the first quarter 2024 included expense related to loans receivable of $960,000 and a credit related to off-balance sheet exposures of $6,000. In the first quarter 2024, the provision related to loans receivable resulted from an increase in qualitative factors and specific allowances on individually evaluated commercial loans, partially offset by reductions in the Corporation’s average net charge-off experience and the impact of an economic forecast used in the calculation of the allowance for credit losses (“ACL”). The credit for credit losses in the first quarter

32

Table of Contents

CITIZENS & NORTHERN CORPORATION – FORM 10-Q

|  | 2023 resulted mainly from a reduction in the allowance related to the commercial segment of the portfolio. The ACL as a percentage of gross loans receivable was 1.07% at March 31, 2024 as compared to 1.05% at March 31, 2023.

​

CRITICAL ACCOUNTING POLICIES

The presentation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect many of the reported amounts and disclosures. Actual results could differ from these estimates.

Allowance for Credit Losses on Loans – A material estimate that is particularly susceptible to significant change is the determination of the allowance for credit losses (ACL) on loans. The Corporation maintains an ACL on loans which represents management’s estimate of expected net charge-offs over the life of the loans. The ACL includes two primary components: (i) an allowance established on loans which share similar risk characteristics collectively evaluated for credit losses (collective basis), and (ii) an allowance established on loans which do not share similar risk characteristics with any loan segment and which are individually evaluated for credit losses (individual basis). Management considers the determination of the ACL on loans to be critical because it requires significant judgment regarding estimates of expected credit losses based on the Corporation’s historical loss experience, current conditions and economic forecasts. Management’s evaluation is based upon a continuous review of the Corporation’s loans, with consideration given to evaluations resulting from examinations performed by regulatory authorities. Note 6 to the unaudited consolidated financial statements provides an overview of the process management uses for determining the ACL, and additional discussion of the ACL is provided in a separate section of Management’s Discussion and Analysis.

The ACL may increase or decrease due to changes in economic conditions affecting borrowers and macroeconomic variables, including new information regarding existing problem loans, identification of additional problem loans, changes in the fair value of underlying collateral, unforeseen events such as natural disasters and pandemics, and other factors. Because current economic conditions and forecasts can change and future events are inherently difficult to predict, the anticipated amount of estimated credit losses on loans, and therefore the appropriateness of the ACL, could change significantly.

Fair Value of Available-For-Sale Debt Securities – Another material estimate is the calculation of fair values of the Corporation’s debt securities. For most of the Corporation’s debt securities, the Corporation receives estimated fair values of debt securities from an independent valuation service, or from brokers. In developing fair values, the valuation service and the brokers use estimates of cash flows, based on historical performance of similar instruments in similar interest rate environments. Based on experience, management is aware that estimated fair values of debt securities tend to vary among brokers and other valuation services.

NET INTEREST INCOME

The Corporation’s primary source of operating income is net interest income, which is equal to the difference between the amounts of interest income and interest expense. Tables IV, V and VI include information regarding the Corporation’s net interest income for the three-month periods ended March 31, 2024 and 2023. In each of these tables, the amounts of interest income earned on tax-exempt securities and loans have been adjusted to a fully taxable-equivalent basis. Management believes presentation of net interest income on a fully taxable-equivalent basis provides investors with meaningful information for purposes of comparing returns on tax-exempt securities and loans with returns on taxable securities and loans. Accordingly, the net interest income amounts reflected in these tables exceed the amounts presented in the consolidated financial statements. The discussion that follows is based on amounts in the related tables.

Three-Month Periods Ended March 31, 2024 and 2023

For the three-month periods, fully taxable equivalent net interest income (a non-GAAP measure) of $19,236,000 in 2024 was $1,814,000 (8.6%) lower than in 2023. The decrease in net interest income reflected an increase in interest expense of $5,937,000 (includes $5,661,000 interest on deposits and $276,000 in interest on borrowings) and an increase of $4,123,000 in total interest income. As presented in Table VI, the net impact of changes in volume of earning assets and interest-bearing liabilities increased net interest income in the first quarter 2024 as compared to first quarter 2023 by $862,000, while the net impact of changes in interest rates (primarily increases) decreased net interest income by $2,676,000. As presented in Table V, the Net Interest Margin was 3.29% in the first quarter 2024 as compared to 3.71% in the first quarter 2023, and the “Interest Rate Spread” (excess of average rate of return on earning assets

over average cost of funds on interest-bearing liabilities) decreased to 2.62% in 2024 from 3.30% in 2023. The average yield on earning assets of 5.22% was 0.56% higher in 2024 as compared to 2023, and the average rate on interest-bearing liabilities of 2.60% in 2024 was 1.24% higher.

INTEREST INCOME AND EARNING ASSETS

Interest income totaled $30,531,000 in 2024, an increase of $4,123,000, or 15.6% from 2023.

Interest and fees from loans receivable increased $4,229,000 in 2024 as compared to 2023. The fully taxable equivalent yield on loans in 2024 increased to 5.92% from 5.44% in 2023, reflecting the effects of rising interest rates on the loan portfolio. Average outstanding loans receivable increased $133,383,000 (7.7%) to $1,859,246,000 in 2024 from $1,725,863,000 in 2023. The Corporation has experienced growth in commercial real estate and other commercial loans in 2023 and the first three months of 2024.

Income from interest-bearing due from banks totaled $383,000 in 2024, an increase of $105,000 from the total for 2023. The average yield on interest-bearing due from banks was 4.71% in 2024, up from 3.56% in 2023. The average balance of interest-bearing due from banks was $32,725,000 in 2024, up from $31,637,000 in 2023. Within this category, the largest asset balance in 2024 and 2023 has been interest-bearing deposits held with the Federal Reserve.

Interest income from available-for-sale debt securities, on a fully taxable-equivalent basis, totaled $2,759,000 in 2024, down $219,000 from 2023, as the average balance (at amortized cost) of available-for-sale debt securities decreased $80,254,000 as indicated in Table V. The average yield on available-for-sale debt securities was 2.41% in 2024, up from 2.23% in 2023.

INTEREST EXPENSE AND INTEREST-BEARING LIABILITIES

Interest expense increased $5,937,000 to $11,295,000 in 2024 from $5,358,000 in 2023.

Interest expense on deposits increased $5,661,000, as the average rate on interest-bearing deposits increased to 2.35% in 2024 from 0.94% in 2023. Average total deposits (interest-bearing and noninterest-bearing) amounted to $2,001,278,000 for the first quarter 2024, up $70,152,000 (3.6%) from the first quarter 2023. Within average total deposits, average brokered deposits (primarily time and money market) were $84,318,000 with an average interest rate of 5.23% in the first quarter 2024, up from $16,179,000 with an average interest rate of 3.04% in the first quarter 2023. The deposit mix has changed as businesses and consumers have become more interest-rate sensitive in light of higher market rates. In comparing the first quarter 2024 to the first quarter 2023, average time deposits increased $116,588,000 and average interest checking deposits increased $57,628,000, while average noninterest-bearing demand deposits decreased $58,513,000 and average savings deposits decreased $43,769,000.

Interest expense on long-term borrowings (FHLB advances) increased $775,000 to $1,456,000 in 2024 from $681,000 in 2023. The average balance of long-term borrowings was $142,753,000 in 2024, up from an average balance of $80,648,000 in 2023. Borrowings are classified as long-term within the Tables based on their term at origination or assumption in business combinations. The average rate on long-term borrowings was 4.10% in 2024 compared to 3.42% in 2023.

INCOME TAXES

The income tax provision in interim periods is based on the Corporation’s estimate of the effective tax rate expected to be applicable for the full year. Due to a lower amount of pre-tax income in 2024, the income tax provision for the first quarter 2024 of $1,152,000 was $257,000 lower than the provision for the first quarter 2023. The effective tax rate (tax provision as a percentage of pre-tax income) was 17.8% in the first quarter 2024 compared to 18.4% in the first quarter 2023. The Corporation’s effective tax rates differ from the statutory rate of 21% principally because of the effects of tax-exempt interest income, nondeductible interest expense, state income taxes and other permanent differences.

The Corporation recognizes deferred tax assets and liabilities based on differences between the financial statement carrying amounts and the tax basis of assets and liabilities. The net deferred tax asset at March 31, 2024 and December 31, 2023 represents the following temporary difference components:

​

​ | ​ | ​ | ​ | ​ | ​ | ​

​

The Corporation regularly reviews deferred tax assets for recoverability based on history of earnings, expectations for future earnings and expected timing of reversals of temporary differences. Realization of deferred tax assets ultimately depends on the existence of sufficient taxable income.

Management believes the recorded net deferred tax asset at March 31, 2024 is fully realizable; however, if management determines the Corporation will be unable to realize all or part of the net deferred tax asset, the Corporation would adjust the deferred tax asset, which would negatively impact earnings.

SECURITIES

Management continually evaluates several objectives in determining the size, securities mix and other characteristics of the available-for-sale debt securities (investment) portfolio. Key objectives include supporting liquidity needs and maximizing return on earning assets within reasonable risk parameters.

As reflected in the table above, the fair value of available-for-sale securities was lower than the amortized cost basis by $51,987,000, or 11.4%, at March 31, 2024, $49,213,000, or 10.6%, at December 31, 2023 and $63,761,000, or 11.3%, at December 31, 2022 while the aggregate unrealized gain position was $6,087,000, or (1.2%) at December 31, 2021. The volatility in the fair value of the portfolio, including the reduction in fair value, resulted from changes in interest rates. As shown above, the market yield on the 5-year U.S. Treasury Note was 0.37% higher at March 31, 2024 in comparison to December 31, 2023, 0.22% higher than at December 31, 2022 and 2.95% higher than at December 31, 2021. The table also shows that the amortized cost basis of the portfolio has been reduced to $457,081,000 at March 31, 2024 from $561,794,000 at December 31, 2022 as proceeds from maturities and sales have been used to help fund loan growth.

Additional information regarding the potential impact of interest rate changes on all of the Corporation’s financial instruments is provided in Item 3, Quantitative and Qualitative Disclosures about Market Risk.

As described in Note 5 to the unaudited consolidated financial statements, management determined the Corporation does not have the intent to sell, nor is it more likely than not that it will be required to sell, available-for-sale debt securities in an unrealized loss position at March 31, 2024 before it is able to recover the amortized cost basis. Further, management reviewed the Corporation’s holdings as of

March 31, 2024 and concluded there were no credit-related declines in fair value. Additional information related to the types of securities held at March 31, 2024, other than securities issued or guaranteed by U.S. Government entities or agencies, is as follows:

| ● | Bank holding company debt securities – All of the Corporation’s holdings of bank holding company debt securities were investment grade and there have been no payment defaults. There were seven securities with face amounts ranging from $3 million to $5 million, including one senior security and six subordinated securities. All of the issuers have publicly traded common stock. At March 31, 2024, the securities have external ratings ranging from BBB-/Baa3 to A-.

| ● | Obligations of states and political subdivisions (municipal bonds) – All of the Corporation’s holdings of municipal bonds were investment grade and there have been no payment defaults. Summary ratings information at March 31, 2024, based on the amortized cost basis and reflecting the lowest enhanced or underlying rating by Moody’s, Standard & Poors or Fitch, is as follows: AAA or pre-refunded – 22% of the portfolio; AA – 71%; A – 7%.

| ● | Private label commercial mortgage-backed securities (PLCMBS) – There were two PLCMBS securities, both of which were from the most senior payment (subordination) classes of their respective issuances. These securities were investment grade (rated Aaa), and there have been no payment defaults on these securities.

Based on the results of management’s assessment, there was no ACL required on available-for-sale debt securities in an unrealized loss position at March 31, 2024.

FINANCIAL CONDITION

This section includes information regarding the Corporation’s lending activities or other significant changes or exposures that are not otherwise addressed in Management’s Discussion and Analysis. Significant changes in the average balances of the Corporation’s earning assets and interest-bearing liabilities are described in the Net Interest Income section of Management’s Discussion and Analysis. Other significant balance sheet items, including securities, the allowance for credit losses and stockholders’ equity, are discussed in separate sections of Management’s Discussion and Analysis. Management does not expect the amount of purchases of bank premises and equipment to have a material, detrimental effect on the Corporation’s financial condition in 2024.

Table VII shows the composition of the loan portfolio at March 31, 2024 and at year-end from 2019 through 2023. The significant loan growth in 2020 reflects the impact of an acquisition of a bank located in Southeastern Pennsylvania. Primarily as a result of the expansion into Southeastern Pennsylvania, as well as expansion by opening two offices in Southcentral Pennsylvania, the mix of the loan portfolio has become predominantly commercial in nature. At March 31, 2024, commercial loans represented 75% of the portfolio while residential loans totaled 22% of the portfolio.

Also included in Table VII is additional detail regarding the composition of the non-owner occupied commercial real estate loan portfolio at March 31, 2024. The data in Table VII shows the recorded investment in non-owner occupied commercial real estate loans for which the primary purpose is utilization of office space by third parties was $93,998,000, or 5.0% of gross loans receivable. At March 31, 2024, within this segment there were two loans with a total recorded investment of $3,899,000 in nonaccrual status with specific allowances totaling $506,000. The remainder of the non-owner occupied commercial real estate loans with a primary purpose of office space utilization were in accrual status with no specific allowance at March 31, 2024. The Provision and Allowance for Credit Losses section of Management’s Discussion and Analysis provides additional related discussion.

While the Corporation’s lending activities are primarily concentrated in its market areas, a portion of the Corporation’s commercial loan segment consists of participation loans. Participation loans represent portions of larger commercial transactions for which other institutions are the “lead banks”. Although not the lead bank, the Corporation conducts detailed underwriting and monitoring of participation loan opportunities. Total participation loans outstanding amounted to $38,252,000 at March 31, 2024 down from $38,652,000 at December 31, 2023.

The Corporation originates and sells residential mortgage loans to the secondary market through the MPF Xtra program administered by the Federal Home Loan Banks of Pittsburgh and Chicago. Residential mortgages originated and sold through the MPF Xtra program consist primarily of conforming, prime loans sold to the Federal National Mortgage Association (Fannie Mae), a quasi-government

entity. The Corporation also originates and sells residential mortgage loans to the secondary market through the MPF Original program, administered by the Federal Home Loan Banks of Pittsburgh and Chicago. Residential mortgages originated and sold through the MPF Original program consist primarily of conforming, prime loans sold to the Federal Home Loan Bank of Pittsburgh. In late 2019, the Corporation began to originate and sell larger-balance, nonconforming mortgages under the MPF Direct Program, which is also administered by the Federal Home Loan Banks of Pittsburgh and Chicago. The Corporation does not retain servicing rights for loans sold under the MPF Direct Program. Through March 31, 2024, the Corporation’s activity under the MPF Direct Program has been minimal.

For loan sales originated under the MPF programs, the Corporation provides customary representations and warranties to investors that specify, among other things, that the loans have been underwritten to the standards established by the investor. The Corporation may be required to repurchase a loan and reimburse a portion of fees received or reimburse the investor for a credit loss incurred on a loan, if it is determined that the representations and warranties have not been met. Such repurchases or reimbursements generally result from an underwriting or documentation deficiency. At March 31, 2024, the total outstanding balance of loans the Corporation has repurchased as a result of identified instances of noncompliance amounted to $1,322,000, and the corresponding total outstanding balance of repurchased loans at December 31, 2023 was $1,335,000.

At March 31, 2024, outstanding balances of loans sold and serviced through the MPF Xtra and Original programs totaled $322,319,000, including loans sold through the MPF Xtra program of $149,219,000 and loans sold through the Original program of $173,100,000. At December 31, 2023, outstanding balances of loans sold and serviced through the two programs totaled $323,298,000, including loans sold through the MPF Xtra program of $150,015,000 and loans sold through the Original Program of $173,283,000. Based on the fairly limited volume of required repurchases to date, no allowance has been established for representation and warranty exposures as of March 31, 2024 and December 31, 2023.

PROVISION AND ALLOWANCE FOR CREDIT LOSSES

A summary of the credit for credit losses for the first quarter 2024 and 2023 is as follows:

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
(In Thousands) | ​ | 3 Months | ​ | 3 Months | ​
​ | ​ | Ended | ​ | Ended | ​

Loans receivable | ​ | $ | 960 | ​ | $ | (312) | ​
Off-balance sheet exposures | ​ |  | (6) | ​ |  | (40) | ​
Total provision (credit) for credit losses | ​ | $ | 954 | ​ | $ | (352) | ​

​

For the quarter ended March 31, 2024, there was a provision for credit losses of $954,000, an increase of $1,306,000 in expense compared to a credit for credit losses (reduction in expense) of $352,000 in the first quarter 2023. The ACL as a percentage of gross loans receivable increased to 1.07% at March 31, 2024 from 1.04% at December 31, 2023; in comparison, the ACL dropped to 1.05% of gross loans receivable at March 31, 2023 from 1.08% upon adoption of CECL on January 1, 2023.

As shown in Table IX, the ACL on loans individually evaluated increased to $1,403,000 at March 31, 2024 from $743,000 at December 31, 2023. The net increase in individual ACLs is primarily related to two borrowers: (1) at March 31, 2024, an ACL of $477,000 was recorded on loans totaling $2,360,000 for land related to a planned commercial construction project, and (2) consistent with an updated collateral valuation assessment, the ACL increased $239,000 to $244,000 at March 31, 2024 on commercial loans to one borrower totaling $284,000 at March 31, 2024. At March 31, 2024, there were seven commercial relationships with loans receivable totaling $10,062,000 for which individual ACLs were recorded, including two non-owner occupied office loans with total outstanding balances of $3,899,000 and individual ACLs totaling $506,000.

Table IX also shows that, at March 31, 2024 as compared to December 31, 2023, the ACL related to collectively evaluated commercial loans increased by a total of $1,125,000, while the ACL on collectively evaluated residential mortgage loans decreased $940,000 and the ACL on collectively evaluated consumer loans decreased $30,000. The increase for commercial loans includes the impact of an increase in outstanding loans and a net increase in qualitative factors used in the ACL evaluation, partially offset by the impact to the ACL valuation of lower estimated net charge-offs based on recent experience and a reduction from the impact of an economic forecast. The decrease for residential mortgage loans includes the impact of a net reduction in qualitative factors, lower net charge-offs based on recent experience and a reduction from the impact of an economic forecast.

Table X shows that total nonperforming assets as a percentage of total assets was 0.78% at March 31, 2024, up from 0.75% at December 31, 2023 and lower than that at year-end 2019 through 2022. Total nonperforming assets were $19.8 million at March 31, 2024, up from $18.8 million at December 31, 2023 but lower than the totals at year-end 2020 through 2022. Nonperforming loans included increases in nonaccrual loans of $3.9 million from December 31, 2023, while loans past due 90 days or more still accruing decreased $3.0 million from December 31, 2023. In the first quarter 2024, the increase in nonaccrual loans included the commercial construction and land loans to one borrower totaling $2,360,000 noted above.

In the first three months of 2024, net charge-offs were low by historical standards, totaling $145,000, or 0.01% of average outstanding loans. Table VIII shows annual average net charge-off rates ranging from a high of 0.26% in 2022 to a low of 0.01% in 2023.

Over the period 2019-2023 and the first quarter of 2024, each period includes a few large commercial relationships that have required significant monitoring and workout efforts. As a result, a limited number of relationships may significantly impact the total amount of allowance required on individual loans and may significantly impact the provision for credit losses and the amount of total charge-offs reported in any one period.

Management believes it has been conservative in its decisions concerning identification of loans requiring individual evaluation for credit loss, estimates of loss, and nonaccrual status; however, the actual losses realized from these relationships could vary materially

from the allowances calculated as of March 31, 2024. Management continues to closely monitor its commercial loan relationships for possible credit losses and will adjust its estimates of loss and decisions concerning nonaccrual status, if appropriate.

Tables VIII through X present historical data related to loans and the allowance for credit losses.

LIQUIDITY

Liquidity is the ability to quickly raise cash at a reasonable cost. An adequate liquidity position permits the Corporation to pay creditors, compensate for unforeseen deposit fluctuations and fund unexpected loan demand.

The Corporation maintains overnight borrowing facilities with several correspondent banks that provide a source of day-to-day liquidity. Also, the Corporation maintains borrowing facilities with the Federal Home Loan Bank of Pittsburgh, secured by various mortgage loans.

The Corporation has a line of credit with the Federal Reserve Bank of Philadelphia’s Discount Window. Management intends to use this line of credit as a contingency funding source. As collateral for the line, the Corporation has pledged available-for-sale debt securities with a carrying value of $20,237,000 at March 31, 2024.

The Corporation’s outstanding, available, and total credit facilities at March 31, 2024 and December 31, 2023 are as follows:

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

​

At March 31, 2024, the Corporation’s outstanding credit facilities with the Federal Home Loan Bank of Pittsburgh consisted of overnight and short-term advances of $47,000,000, long-term borrowings of $148,810,000 and letters of credit totaling $19,208,000. At December 31, 2023, the Corporation’s outstanding credit facilities with the Federal Home Loan Bank of Pittsburgh consisted of overnight and short-term borrowings of $31,500,000, long-term borrowings of $138,313,000 and letters of credit totaling $19,208,000. Additional information regarding borrowed funds is included in Note 8 to the unaudited consolidated financial statements.

Additionally, the Corporation uses “RepoSweep” arrangements to borrow funds from commercial banking customers on an overnight basis. If required to raise cash in an emergency situation, the Corporation could sell available-for-sale securities to meet its obligations or use repurchase agreements placed with brokers to borrow funds secured by investment assets. At March 31, 2024, the carrying value of available-for-sale securities in excess of amounts required to meet pledging or repurchase agreement obligations was $259,489,000.

Deposits totaled $1,995,903,000 at March 31,2024, down $18,903,000 (0.9%) from $2,014,806,000 at December 31, 2023. Excluding brokered deposits, adjusted total deposits at March 31, 2024 were lower by $23,925,000 (1.2%) as compared to December 31, 2023. Brokered deposits totaled $69,391,000 at March 31, 2024, an increase of $5,522,000 from December 31, 2023. The reduction in total deposits, excluding brokered deposits, included a reduction in total deposits from municipal relationships of $20,321,000 to $257,391,000 at March 31, 2024 from $277,712,000 at December 31, 2023, consistent with historic seasonal trends for the Corporation’s Pennsylvania-based municipal depositors.

As shown in the table below, at March 31, 2024, estimated uninsured deposits totaled $568.1 million, or 28.2% of total deposits, down from $592.2 million or 29.2% of total deposits at December 31, 2023. Included in uninsured deposits are deposits collateralized by securities (almost exclusively municipal deposits) totaling $140.1 million at March 31, 2024. As shown in the table below, total uninsured and uncollateralized deposits amounted to 21.3% of total deposits at March 31, 2024, down from 21.7% at December 31, 2023.

As summarized in the table that immediately follows, the Corporation’s highly liquid sources of available funds described above, including unused borrowing capacity with the Federal Home Loan Bank of Pittsburgh, unused availability on the Federal Reserve Bank of Philadelphia’s discount window, available federal funds lines with other banks and unencumbered available-for-sale debt securities totaled $1.1 billion at March 31, 2024. Available funding from these sources totaled 187.7% of uninsured deposits and 249.2% of total uninsured and uncollateralized deposits at March 31, 2024.

STOCKHOLDERS’ EQUITY AND CAPITAL ADEQUACY

In August 2018, the Federal Reserve Board issued an interim final rule that expanded applicability of the Board’s small bank holding company policy statement. The interim final rule raised the policy statement’s asset threshold from $1 billion to $3 billion in total consolidated assets for a bank holding company or savings and loan holding company that: (1) is not engaged in significant nonbanking activities; (2) does not conduct significant off-balance sheet activities; and (3) does not have a material amount of debt or equity securities, other than trust-preferred securities, outstanding. The interim final rule provides that, if warranted for supervisory purposes, the Federal Reserve may exclude a company from the threshold increase. Management believes the Corporation meets the conditions of the Federal Reserve’s small bank holding company policy statement and is therefore excluded from consolidated capital requirements at March 31, 2024; however, C&N Bank remains subject to regulatory capital requirements administered by the federal banking agencies.

Details concerning capital ratios at March 31, 2024 and December 31, 2023 are presented below. Management believes, as of March 31, 2024, that C&N Bank meets all capital adequacy requirements to which it is subject and maintains a capital conservation buffer (described in more detail below) that allows the Bank to avoid limitations on capital distributions, including dividend payments and certain discretionary bonus payments to executive officers. Further, as reflected in the table below, the Corporation’s and C&N Bank’s capital ratios at March 31, 2024 and December 31, 2023 exceed the Corporation’s Board policy threshold levels.

On September 25, 2023, the Corporation announced a new treasury stock repurchase program. Under the program, the Corporation is authorized to repurchase up to 750,000 shares of the Corporation’s common stock, or slightly less than 5% of the Corporation’s issued and outstanding shares at August 4, 2023. The new program was effective when publicly announced and will continue thereafter until suspended or terminated by the Board of Directors, in its sole discretion. All shares of common stock repurchased pursuant to the new program shall be held as treasury shares and be available for use and reissuance for purposes as and when determined by the Board of Directors including, without limitation, pursuant to the Corporation’s Dividend Reinvestment and Stock Purchase Plans and its equity compensation program. Through March 31, 2024, no shares were repurchased under the new program.

Future dividend payments and repurchases of common stock will depend upon maintenance of a strong financial condition, future earnings and capital and regulatory requirements. In addition, the Corporation and C&N Bank are subject to restrictions on the amount of dividends that may be paid without approval of banking regulatory authorities. Further, although the Corporation is no longer subject to the specific consolidated capital requirements described herein, the Corporation’s ability to pay dividends, repurchase stock or engage in other activities may be limited by the Federal Reserve if the Corporation fails to hold capital commensurate with its overall risk profile.

CITIZENS & NORTHERN CORPORATION – FORM 10-Q

To avoid limitations on capital distributions, including dividend payments and certain discretionary bonus payments to executive officers, a banking organization subject to the rule must hold a capital conservation buffer composed of common equity tier 1 capital above its minimum risk-based capital requirements. The buffer is measured relative to risk-weighted assets. At March 31, 2024, the minimum risk-based capital ratios, and the capital ratios including the capital conservation buffer, are as follows:

​

​ | ​ | ​ | ​
Minimum common equity tier 1 capital ratio |  | 4.5 | %
Minimum common equity tier 1 capital ratio plus capital conservation buffer |  | 7.0 | %
Minimum tier 1 capital ratio |  | 6.0 | %
Minimum tier 1 capital ratio plus capital conservation buffer |  | 8.5 | %
Minimum total capital ratio |  | 8.0 | %
Minimum total capital ratio plus capital conservation buffer |  | 10.5 | %

​

A banking organization with a buffer greater than 2.5% over the minimum risk-based capital ratios would not be subject to additional limits on dividend payments or discretionary bonus payments; however, a banking organization with a buffer less than 2.5% would be subject to increasingly stringent limitations as the buffer approaches zero. Also, a banking organization is prohibited from making dividend payments or discretionary bonus payments if its eligible retained income is negative in that quarter and its capital conservation buffer ratio was less than 2.5% as of the beginning of that quarter. Eligible net income is defined as net income for the four calendar quarters preceding the current calendar quarter, net of any distributions and associated tax effects not already reflected in net income. A summary of payout restrictions based on the capital conservation buffer is as follows:

​

​ | ​ | ​ | ​
Capital Conservation Buffer |  | Maximum Payout |
(as a % of risk-weighted assets) | ​ | (as a % of eligible retained income) |
Greater than 2.5% | ​ | No payout limitation applies | ​
≤2.5% and >1.875% | ​ | 60 | %
≤1.875% and >1.25% | ​ | 40 | %
≤1.25% and >0.625% | ​ | 20 | %
≤0.625% | ​ | 0 | %

​

At March 31, 2024, C&N Bank’s Capital Conservation Buffer, determined based on the minimum total capital ratio, was 6.77%.

The Corporation’s total stockholders’ equity is affected by fluctuations in the fair values of available-for-sale debt securities. The difference between amortized cost and fair value of available-for-sale debt securities, net of deferred income tax, is included in accumulated other comprehensive (loss) income within stockholders’ equity. Accumulated other comprehensive (loss) income is excluded from the Bank’s and Corporation’s regulatory capital ratios. The balance in accumulated other comprehensive loss related to unrealized losses on available-for-sale debt securities, net of deferred income tax, amounted to $41,071,000 at March 31, 2024 and $38,878,000 at December 31, 2023. The decrease in stockholders’ equity in the first three months of 2024 from the change in accumulated other comprehensive loss resulted from an increase in interest rates. Changes in accumulated other comprehensive loss are excluded from earnings and directly increase or decrease stockholders’ equity. To the extent unrealized losses on available-for-sale debt securities result from credit losses, unrealized losses are recorded as a charge against earnings. The securities section of Management’s Discussion and Analysis and Note 5 to the unaudited consolidated financial statements provide additional information concerning management’s evaluation of available-for-sale debt securities for credit losses at March 31, 2024.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

MARKET RISK

Market risk is the risk of loss arising from adverse changes in market rates and prices of the Corporation’s financial instruments. In addition to the effects of interest rates, the market prices of the Corporation’s available-for-sale debt securities are affected by fluctuations in the risk premiums (amounts of spread over risk-free rates) demanded by investors. Management attempts to limit the risk that economic conditions would force the Corporation to sell securities for realized losses by maintaining a strong capital position (discussed in the “Stockholders’ Equity and Capital Adequacy” section of Management’s Discussion and Analysis) and ample sources of liquidity (discussed in the “Liquidity” section of Management’s Discussion and Analysis).

The Corporation’s major category of market risk, interest rate risk, is discussed in the following section.

INTEREST RATE RISK

The Corporation uses a simulation model to calculate the potential effects of interest rate fluctuations on net interest income and the economic value of equity. For purposes of these calculations, the economic value of equity includes the discounted present values of financial instruments, such as securities, loans, deposits and borrowed funds, and the book values of nonfinancial assets and liabilities, such as premises and equipment and accrued expenses. The model measures and projects the amount of potential changes in net interest income, and calculates the discounted present value of anticipated cash flows of financial instruments, assuming an immediate increase or decrease in interest rates. Management ordinarily runs a variety of scenarios within a range of plus or minus 100-400 basis points of current rates.

The projected results based on the model includes the impact of estimates, at each level of interest rate change, regarding cash flows from principal repayments on loans and mortgage-backed securities and call activity on other investment securities. Further, the projected results are impacted by assumptions regarding the run-off and the extent of sensitivity to interest rate changes of deposits with no stated maturity (checking, savings and money market accounts). Actual results could vary significantly from these estimates, which could result in significant differences in the calculations of projected changes in net interest income and economic value of equity. Also, the model does not make estimates related to changes in the composition of the deposit portfolio that could occur due to rate competition, and the table does not necessarily reflect changes that management would make to realign the portfolio as a result of changes in interest rates.

The Corporation’s Board of Directors has established policy guidelines for acceptable levels of interest rate risk, based on an immediate increase or decrease in interest rates. The policy limits acceptable fluctuations in net interest income from the baseline (flat rates) one-year scenario and variances in the economic value of equity from the baseline values based on current rates.

​

Table XI, which follows this discussion, is based on the results of calculations performed using the simulation model as of March 31, 2024 and December 31, 2023. In the analysis based on March 31, 2024 and December 31, 2023 data, the amounts of net interest income decrease, as compared to the amounts based on current interest rates, in both the upward and downward rate scenarios. Further, at March 31, 2024 and December 31, 2023, the economic value of equity is modeled to decrease in all of the rising and falling rate scenarios. The modeling results reflect the impact of management’s assumptions that, in light of the significant increases in short-term interest rates that have occurred since early 2022, the Corporation’s deposit rates would rise in the increasing rate scenarios to a greater extent than they would fall in the decreasing rate scenarios. Further, results in the downward rate scenarios reflect limitations on the benefit of falling rates on some deposit types due to a 0% assumed floor. The Table also shows that as of the respective dates, the changes in net interest income and changes in economic value were within the policy limits in all scenarios.

​

Under U.S. generally accepted accounting principles, available-for-sale debt securities are carried at fair value as of each balance sheet date. The difference between amortized cost and fair value of available-for-sale debt securities, net of deferred income tax, is included in accumulated other comprehensive income (loss) within stockholders’ equity. Increases in interest rates have caused the fair value of the Corporation’s available-for-sale debt securities to decrease, resulting in an accumulated other comprehensive loss of $41.1 million at March 31, 2024. In contrast, most of the Corporation’s other financial instruments, including loans receivable (held for investment),

deposits and borrowed funds are carried on the balance sheet at historical cost without adjustment for the impact of changes in interest rates.
