Organization, Consolidation and Presentation of Financial Statements [Abstract]
Use of Estimates	Use of Estimates The Company follows GAAP and reporting practices applicable to the banking industry. The preparation of the financial statements under GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and notes. These estimates are based on information available to management at the time the estimates are made. While the consolidated financial statements reflect management’s best estimates and judgments, actual results could differ. Significant estimates include, but are not limited to, the allowance for credit losses on loans and investment securities, the valuation of investment securities and mortgage servicing rights, goodwill impairment assessments, and pension obligations. These estimates are based on management’s evaluation of historical experience, current conditions, and reasonable and supportable forecasts.
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of the consolidated statements of cash flows, the Company considers cash and due from banks, short-term interest-bearing deposits maturing within 90 days, and federal funds sold and securities purchased under agreements to resell maturing within 90 days to be cash equivalents. Interest-bearing deposits are held at other financial institutions and are not considered cash and cash equivalents.
Investment Securities	Investment Securities Held-to-maturity securities are those that the Company has the positive intent and ability to hold to maturity. HTM securities are recorded at amortized cost, net of allowance for credit losses. Trading account securities (“Trading”) are bought and held principally for the purpose of selling them in the near term. Equity securities (“Equity”) include common and preferred stock with readily determinable fair value as well as certain equity securities without a readily determinable fair value. All other debt securities held by the Company are classified as available-for-sale. Trading, Equity, and AFS securities are recorded at fair value. For both Trading and Equity securities, gains and losses, both realized and unrealized, are included in earnings. Unrealized gains and losses, net of related tax effect, on AFS securities are excluded from earnings and are reported as a separate component of accumulated other comprehensive income (loss) until realized. Realized gains and losses upon disposition of AFS securities are included in income using the specific-identification method for determining the cost of the securities sold. Purchased premiums and discounts on investment securities are amortized/accreted into interest income using the constant yield method based upon the remaining contractual maturity of the asset, adjusted for any expected prepayments. For certain callable debt securities purchased at a premium, the amortization is recorded to the earliest call date. For mortgage and asset-backed securities, prepayment experience is evaluated monthly to determine if a change in a bond's estimated remaining life is necessary. A corresponding adjustment is then made in the related amortization of premium or discount accretion. Other securities include Federal Reserve and Federal Home Loan Bank stock, which represent equity interests the Company is required to hold in the Federal Reserve Banks and Federal Home Loan Banks. These amounts are carried at cost as they do not have a readily determinable fair value because ownership of these shares is restricted, and they lack a market. Purchases and sales of securities are recognized on a trade date basis. A receivable or payable is recognized for transactions pending settlements.
Allowance for Credit Losses on Available-for-Sale Debt Securities And Allowance for Credit Losses on Loans	Allowance for Credit Losses on Available-for-Sale Debt Securities For AFS debt securities in an unrealized loss position, the entire loss in fair value is required to be recognized in current earnings if the Company intends to sell the securities or believes it more likely than not that it will be required to sell the security before the anticipated recovery. Any time the Company does not expect to recover the amortized cost basis, a credit loss is deemed to have occurred and an allowance for credit losses is recorded. The allowance for credit losses is limited by the amount that the fair value is less than the amortized cost basis. All securities not issued or guaranteed by the U.S. government, its agencies, or sponsored enterprises are subject to a quarterly review to test for impairment. This process is intended to adequately test a range of credit and loss assumptions and does not rely primarily on credit ratings. Changes in the allowance for credit losses are recorded as a provision for (or reversal of) credit losses on the consolidated statements of income. Losses are charged against the allowance for credit losses on securities when management believes the inability to collect an AFS security is confirmed or when either of the conditions regarding intent or requirement to sell is met. Accrued interest receivable on available for sale debt securities is reported in other assets on the consolidated balance sheet. The Company has elected the practical expedient to exclude the accrued interest from all required disclosures of amortized cost of debt securities. Additionally, an election was made not to measure an allowance for credit losses for accrued interest receivables. Interest accrued but not received is reversed against interest income. Allowance for Credit Losses on Loans The allowance for credit losses on loans is a valuation amount that is deducted from the amortized cost basis of loans not held at fair value to present the net amount expected to be collected over the contractual term of the loans. The allowance reflects management’s best estimate of expected credit losses, considering portfolio segmentation, historical loss experience, current conditions, and reasonable and supportable forecasts. Management applies qualitative adjustments to model outputs when appropriate to address factors not fully captured by the quantitative models. An allowance will be created upon origination or acquisition of a loan and is updated at subsequent reporting dates. The methodology is applied consistently for each reporting period. Changes to the allowance for credit losses on loans resulting from periodic evaluations are recorded through increases or decreases to the credit loss expense for loans, which is recorded in provision for credit losses on the consolidated statements of income. Loans that are deemed to be uncollectible are charged off against the related allowance for credit losses on loans. The allowance for credit losses on loans is measured on a collective (pool) basis. Loans are aggregated into pools based on similar risk characteristics including borrower type, collateral type, and expected credit loss patterns. The Company maintains a policy to reverse accrued and unpaid interest when a loan is placed on non-accrual. Therefore, an allowance is not recorded for accrued interest.
Loans Held for Sale	Loans Held for Sale Loans held for sale are accounted for at fair value pursuant to the fair value option permitted by ASC 825, Financial Instruments. The Company elected to take the fair value option for loans held for sale permitted by ASC 825, Financial Instruments beginning January 1, 2020. The fair value is based on secondary market prices for loans with similar characteristics, including an adjustment for embedded servicing value. Gains and losses from the changes in fair value are included in mortgage banking revenues. Deferred fees and costs related to these loans are recognized as part of the cost basis of the loan at the time it is sold. Interest income related to loans held for sale is accrued based on the principal amount outstanding and the loan's contractual interest rate.
Loans	Loans For purposes of these financial statements, the loan portfolio collectively includes all loans and leases the Company holds for investment, hereinafter referred to as “loans.” Loans that the Company intends and has the ability to hold for the foreseeable future or until maturity or payoff are carried at amortized cost. Amortized cost represents the outstanding principal balance of loans, net of any deferred origination fees and related costs. The Company has elected to exclude all accrued interest receivable from the disclosures of amortized cost and has opted not to establish an allowance for credit losses related to accrued interest receivables. Interest on loans is accrued and credited to income based on the principal amount outstanding, using primarily a simple interest calculation. Loan and commitment fees, net of associated costs, are deferred and amortized over the life of the loans, shown as an adjustment to interest income. The Company applies the straight-line method for amortization, which approximates the level yield method. Amortization does not anticipate loan prepayments, and any unamortized fees are recognized in full at the time of payoff. The accrual of interest on loans is discontinued when, (a) in management’s judgment, the interest is uncollectible in the normal course of business; or (b) when they become 90 days or more past due, unless they are well‑secured and in the process of collection. When a loan is placed on non-accrual status, any interest previously accrued but not collected is reversed against current income, and the loan is charged off to the extent uncollectible. Principal and interest payments received on non-accrual loans are generally applied to principal. Interest is included in income only after all previous loan charge-offs have been recovered and is recorded only as received. The loan is returned to accrual status only when the borrower has brought all past-due principal and interest payments current and, in the opinion of management, has demonstrated the ability to make future payments of principal and interest as scheduled. Loan Modifications and Borrower Financial Difficulty The Company may renegotiate the terms of existing loans during the normal course of business. When modifications are made to the terms of an existing loan, the Company assesses whether a borrower is experiencing financial difficulty. This assessment is performed in accordance with ASC 326 and considers both quantitative and qualitative indicators. The Company considers delinquency status, cash flow capacity, collateral performance, and the borrower’s ability to obtain alternative financing at market terms. Loan modifications are subject to established credit approval and oversight processes.
Liability for Unfunded Lending Commitments	Liability for Unfunded Lending Commitments The Company’s accrual for credit risk associated with unfunded lending commitments is maintained at a level that is appropriate to cover estimated losses associated with credit instruments that are not currently recognized as assets such as loan commitments, standby letters of credit or guarantees that are not unconditionally cancellable by the bank. This accrual is included in other liabilities in the consolidated balance sheets with changes to the liability recorded through increases or decreases to the provision for credit losses on the consolidated statements of income. The methodology used to measure credit losses for unfunded lending commitments is the same as the methodology used for loans, however, the estimate of credit risk for unfunded lending commitments takes into consideration the likelihood that funding will occur. The liability for unfunded lending commitments excludes any exposures that are unconditionally cancellable by the Company.
Land, Buildings, and Equipment	Land, Buildings, and Equipment Land, buildings, and equipment are stated at cost less accumulated depreciation. Depreciation is computed on the straight-line or declining balance method depending upon the type of asset. The Company generally assigns depreciable lives of 25-30 years for buildings; 15 years for building improvements; 15 years for land improvements; and 3-7 years for furniture, equipment, and software. Leasehold improvements are assigned depreciable lives of the shorter of the lease term or 15 years. Maintenance and repair costs are charged to expense as incurred. Major improvements are individually considered and are capitalized or expensed as the facts dictate.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill represents the excess of cost over equity in net assets of entities acquired. The Company accounts for goodwill in accordance with ASC 350, Intangibles – Goodwill and Other. Under ASC 350, goodwill and intangible assets that have indefinite useful lives are not amortized but rather tested at least annually for impairment. Intangible assets that have finite useful lives continue to be amortized over 7 to 20 years. The Company performs an annual qualitative evaluation of goodwill. Based on the results of this qualitative assessment, if the Company concludes it is more likely than not that a reporting unit's fair value is less than its carrying amount, a quantitative analysis is performed. If the fair value of a reporting unit is less than the carrying amount, an impairment has occurred and is measured as the amount by which the carrying amount exceeds the reporting unit's fair value. During 2025, the Company completed its annual qualitative impairment assessment and concluded that it was not more likely than not that the fair value of any of its reporting units was below its respective carrying amount. The Company has not recorded impairment resulting from goodwill impairment tests during the years ended December 31, 2025 and 2024.
Foreclosed Assets	Foreclosed Assets Foreclosed assets represent property that has been repossessed following default on a loan. These assets primarily consist of commercial and residential real estate, as well as other non-real estate property such as automobiles. Upon foreclosure, the assets are initially recognized at fair value, less estimated costs to sell, with any necessary valuation adjustments reflected in the allowance for credit losses. The fair value of foreclosed assets is generally determined based on independent appraisals, third-party price opinions, or internally developed pricing models. These fair value estimates are reviewed and updated periodically to help ensure they accurately reflect market conditions. Subsequent declines in fair value below the carrying amount are recognized through valuation allowances, which may be reversed if future increases in fair value occur. Any adjustments to the carrying value, along with realized gains or losses on the sale of foreclosed assets, as well as net operating expenses related to these assets, are recorded within other expenses.
Income Taxes	Income Taxes The Company and its subsidiaries file a consolidated federal income tax return. State and local income tax returns are filed on a combined, consolidated, or separate return basis based upon each jurisdiction’s laws and regulations. Deferred tax assets and liabilities are recognized based upon the differences between the values of assets and liabilities as recognized in the financial statements and their related tax basis using enacted tax rates in effect for the year in which the differences are expected to be recovered or settled. The effect of changes in statutory tax rates on the measurement of deferred tax assets and liabilities is recognized through income tax expense in the period the change is enacted. A valuation allowance is provided when it is more likely than not that some portion of the entire deferred tax asset may not be realized.
Revenue Recognition	Revenue Recognition Revenue should be recognized to reflect the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Revenue from financial instruments, including revenue from loans and securities, is not included within this guidance. Noninterest revenue items that are subject to this guidance mainly include fees for bank card, trust, deposit account services, and consumer brokerage services and are discussed below and summarized in the table that follows. Fees for Fiduciary Services Trust and asset management income is primarily comprised of fees earned from the management and administration of trusts, settlement of estates, and other similar duties where Central Trust Company serves in a fiduciary capacity. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the average monthly value of the assets under management and the applicable fee rate or otherwise as negotiated as a fee for service. Other transactional-based services, including but not limited to, tax return preparation and financial planning are available. The performance obligation for these services is generally satisfied, and related revenue recognized, at the completion of the service. Service Charges and Commissions Service charges on deposit accounts consist of account analysis fees (i.e., net fees earned on analyzed business and public checking accounts), monthly service fees, check orders, and other deposit account related fees. The Company's performance obligation for account analysis and monthly service fees is generally satisfied, and the related revenue recognized, when the service is provided and received immediately or in the following month. The Company provides corporate cash management services to its business customers to meet their various transaction processing needs. Such services include deposit and check processing, lockbox, remote deposit, reconciliation, online banking, and other similar transaction processing services. The Company maintains unit prices for each type of service, and the customer is billed based on transaction volumes processed monthly. Overdraft fees are charged to customers when daily checks and other withdrawals to customers’ accounts exceed balances on hand. The daily overdraft charge is calculated and the fee is posted to the customer’s account each day. Other deposit related fees such as check orders, foreign ATM processing fees, stop payment fees, and cashier’s checks are largely transactional based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, when the transaction is processed. Payment Services Revenue Payment services revenue includes bankcard transaction fees, exchange, and other service charges that are primarily comprised of debit and credit card income, ATM fees, merchant services income, and other service charges. Debit and credit card income is primarily comprised of interchange fees earned whenever the Company’s debit and credit cards are processed through card payment networks such as MasterCard. The fees earned are established by the settlement network and are dependent on the type of transaction processed but are typically based on a per unit charge. Interchange income is settled daily through the networks. Brokerage Services Brokerage services revenue is comprised of commissions received upon the execution of purchases and sales of mutual fund shares and equity securities, in addition to certain limited insurance products in an agency capacity. Also, fees are earned on managed advisory programs. Payment from the customer is upon settlement for purchases and sales of securities, upon purchase for annuities and insurance products, and upon inception of the service period for advisory programs. Other Non-Interest Income from Contracts with Customers Other non-interest income consists of gains on foreclosed assets, bank premises and equipment, official check fees, international currency commissions, and other miscellaneous consumer product fees. Performance obligations for these services consist mainly of the execution of transactions for the sale of various properties. Fees from these revenue sources are recognized when the performance obligation is completed, at which time cash is received by the Company.
Comprehensive Income	Comprehensive Income Comprehensive income is defined as the change in equity (net assets) of a business enterprise during a period from transactions and other events and circumstances from nonowner sources. For the Company, this includes net income, changes in unrealized gains and losses on AFS investment securities, and the net periodic benefit/cost related to the Company’s defined benefit pension plan, net of applicable tax effects. The amounts recognized in accumulated other comprehensive loss related to the defined benefit pension plan are adjusted out of accumulated other comprehensive loss when they are subsequently recognized as components of net periodic benefit cost.
Mortgage Banking	Mortgage Banking The fair value of retained mortgage servicing rights related to loans originated and sold is capitalized as an asset in accordance with ASC 860, Accounting for Servicing of Financial Assets, thereby increasing the gain on sale of the loan. Such mortgage servicing rights are amortized in proportion to and over the period of estimated net servicing income, considering appropriate prepayment assumptions. Any remaining unamortized amount is charged to expense if the related loan is repaid prior to maturity. Management monitors the capitalized mortgage servicing rights on a disaggregated basis for impairment based on the fair value of those rights. Any impairment is recognized through a valuation allowance.
Derivative Financial Instruments	Derivative Financial Instruments ASC 815, Derivatives and Hedging, establishes accounting and reporting standards for derivative instruments, including certain derivatives embedded in other contracts, and for hedging activities. In accordance with ASC 815, the Company records all derivative instruments at fair value on the consolidated balance sheets. Mortgage Banking Derivatives: The Company’s mortgage banking operations involve the origination of mortgage loans under interest rate lock commitments that are intended for sale into the secondary market. IRLCs represent commitments to originate loans with interest rates determined prior to funding and are accounted for as derivatives. The Company generally does not enter into sales commitments for these loans at the time the IRLC is issued; instead, it commits to sell the loans after funding. To economically hedge the interest rate risk associated with IRLCs and funded loans awaiting sale, the Company enters into free‑standing derivative instruments, primarily commitments to sell TBA mortgage‑backed securities. The value of TBA commitments generally moves inversely with fixed‑rate mortgage loan values, thereby providing an economic offset to changes in interest rates. The Company also sells certain mortgage loans on a mandatory delivery basis and enters into short positions in mortgage‑backed securities to hedge interest rate exposure associated with these transactions. IRLCs and related derivative instruments are recorded at fair value in other assets or other liabilities, with changes in fair value recognized in mortgage banking revenues, net.
Customer Repurchase Agreements	Customer Repurchase Agreements The Company engages in customer transactions involving the sale of securities under agreements to repurchase as of a specified future date. Such repurchase agreements are considered collateralized financing transactions, not as a sale of the underlying securities. The obligation to repurchase assets sold is reflected as a liability in the consolidated balance sheet of the Company at the amount of cash received in the transaction. The fair value of collateral provided to a counterparty is monitored daily, and collateral is returned or provided by the Company in order to maintain full collateralization for these transactions.
Stock Based Compensation	Stock Based Compensation The Company’s stock-based compensation plan, as detailed in "Note 11, Stock-Based Compensation,” to our consolidated financial statements is accounted for in accordance with the guidance set forth in ASC 718, Compensation—Stock Compensation. Specifically, the Company adheres to the provisions outlined in ASC 718-10-30-3 and ASC 718-10-35-2, which require the measurement of stock-based compensation based on the fair value of the awards granted at the grant date. The fair value for restricted stock awards (RSAs) is based on the weighted average market price of the Company’s common stock during a specified period that is within 30 days before or 30 days after grant date, as determined by the Board of Directors in its sole discretion. The cost of stock-based compensation is recognized over the requisite service period, which is typically the vesting period, in accordance with the principles of ASC 718. The Company recognizes stock-based compensation expense in the consolidated statements of income within “Salaries and Benefits.” The expense is recognized over the vesting period, with the total expense being adjusted for forfeitures only when they occur, in line with the policy outlined under ASC 718. Forfeitures are accounted for on an actual basis, and no estimated forfeitures are included in the initial measurement of compensation cost.
Treasury Stock	Treasury Stock The Company accounts for treasury stock under the cost method, as outlined in ASC 505-30, Equity—Treasury Stock. Purchases of the Company’s common stock are recorded at cost, which includes all direct costs associated with the acquisition. When treasury stock is reissued, the carrying value of treasury stock is reduced based on the average cost basis of the shares held in treasury.
Income Per Share	Income Per Share The Company applies the two-class method for the computation of income per share, as prescribed by ASC 260, Earnings Per Share. The two-class method is an earnings allocation formula that determines income per share for common stock and for participating securities, according to dividends declared and participation rights in undistributed earnings. The Company’s nonvested share-based awards vest based on the satisfaction of service conditions and are subject to forfeiture until such conditions are met. These nonvested share-based awards are not considered participating securities for the purpose of calculating income per share and as such do not participate in undistributed earnings. However, dividends or dividend equivalents declared or paid on nonvested share-based awards with forfeitable dividend rights are deducted from the income available to common stockholders. Such amounts reflect dividends that have been allocated to other-than-common stockholders and reduce the amount of income available for distribution to common stockholders.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Income Taxes – In December 2024, the FASB issued ASU 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures. This update establishes additional disclosure requirements regarding rate reconciliation and income taxes paid. This update also removes certain existing disclosure requirements. This update is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The amendments in this update have been applied on a retrospective basis. Other than the inclusion of additional disclosures, the change did not have a significant impact on the Company’s consolidated financial statements. Income Statement Reporting – In November 2024, The FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The amendments in this update require new disclosures providing further detail of a company's income statement expense items. This update is effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted. The amendments in this update should be applied on a prospective basis. The Company is currently assessing the impact ASU 2024-03 will have on its expense disclosures. Credit Losses – In July 2025, the FASB issued ASU 2025-05, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. This update allows entities to use current, static conditions instead of forecasting future economic conditions to determine expected credit losses for accounts receivable assets and contra assets. This update is effective for annual periods beginning after December 15, 2025, including interim periods within those fiscal years. The Company is currently assessing the impact ASU 2025-05 will have on its allowance for credit losses. Intangible Assets – In September 2025, the FASB issued ASU 2025-06, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. This update replaces the current timing of capitalization for internal-use software expenditures, which uses the three-stage approach (preliminary, application, post-implementation). The update now allows entities to capitalize costs when management commits to funding and it is probable the project will be completed and perform the intended function (the “probable-to-complete” threshold). This update is effective for annual periods beginning after December 15, 2027, including interim periods within those fiscal years. The Company is currently assessing the impact ASU 2025-06 will have on its income statement. Derivatives and Hedging – In September 2025, the FASB issued ASU 2025-07, Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606): Derivatives Scope Refinements and Scope Clarification for Share-Based Noncash Consideration from a Customer in a Revenue Contract. This update refines the scope of Topic 815 by adding an exception from derivative accounts for contracts that are not exchange traded and have underlying assets based on operations or activities specific to one of the parties to the contract. It also clarifies that revenue guidance in Topic 606 applies initially to share-based noncash consideration received from a customer for the transfer of goods or services. This update is effective for annual periods beginning after December 15, 2026, including interim periods within those fiscal years. The Company is currently assessing the impact ASU 2025-07 will have on its consolidated financial statements. Purchased Loans – In November 2025, the FASB issued ASU 2025-08, Financial Instruments – Credit Losses (Topic 326): Purchased Loans. This update expands the method used for Purchased Credit Deteriorated (PCD) loans to Purchased Seasoned Loans (PSL), allowing the initial allowance for credit losses to be added to the purchase price, rather than recognized as an immediate expense. This applies to loans that are acquired in a business combination or purchased more than 90 days after origination. This update is effective for annual periods beginning after December 15, 2026, including interim periods within those fiscal years. The Company is currently assessing the impact ASU 2025-08 will have on its allowance for credit losses. Derivatives and Hedging - In November 2025, the FASB issued ASU 2025‑09, Derivatives and Hedging (Topic 815): Hedge Accounting Improvements. This update refines hedge accounting to better align financial reporting with risk‑management activities. Enhancements include expanded eligibility for certain hedging strategies and simplifications to ongoing hedge effectiveness assessments. This update is effective for annual periods beginning after December 15, 2026, including interim periods within those fiscal years. The Company is assessing the impact ASU 2025‑09 will have on its risk‑management accounting strategies. Interim Reporting - In December 2025, the FASB issued ASU 2025‑11, Interim Reporting (Topic 270): Narrow‑Scope Improvements. This update enhances interim disclosure requirements and clarifies the application of certain interim reporting principles. It aims to improve the usefulness and consistency of interim financial information across entities. The update is effective for annual periods beginning after December 15, 2027, including interim periods within those fiscal years. The Company is currently assessing the impact ASU 2025‑11 will have on its interim reporting disclosures.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

The Company follows GAAP and reporting practices applicable to the banking industry. The preparation of the financial statements under GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and notes. These estimates are based on information available to management at the time the estimates are made. While the consolidated financial statements reflect management’s best estimates and judgments, actual results could differ.

Significant estimates include, but are not limited to, the allowance for credit losses on loans and investment securities, the valuation of investment securities and mortgage servicing rights, goodwill impairment assessments, and pension obligations. These estimates are based on management’s evaluation of historical experience, current conditions, and reasonable and supportable forecasts.

Cash and Cash Equivalents

For purposes of the consolidated statements of cash flows, the Company considers cash and due from banks, short-term interest-bearing deposits maturing within 90 days, and federal funds sold and securities purchased under agreements to resell maturing within 90 days to be cash equivalents. Interest-bearing deposits are held at other financial institutions and are not considered cash and cash equivalents.

Investment Securities

Held-to-maturity securities are those that the Company has the positive intent and ability to hold to maturity. HTM securities are recorded at amortized cost, net of allowance for credit losses. Trading account securities (“Trading”) are bought and held principally for the purpose of selling them in the near term. Equity securities (“Equity”) include common and preferred stock with readily determinable fair value as well as certain equity securities without a readily determinable fair value. All other debt securities held by the Company are classified as available-for-sale. Trading, Equity, and AFS securities are recorded at fair value. For both Trading and Equity securities, gains and losses, both realized and unrealized, are included in earnings. Unrealized gains and losses, net of related tax effect, on AFS securities are excluded from earnings and are reported as a separate component of accumulated other comprehensive income (loss) until realized. Realized gains and losses upon disposition of AFS securities are included in income using the specific-identification method for determining the cost of the securities sold.

Purchased premiums and discounts on investment securities are amortized/accreted into interest income using the constant yield method based upon the remaining contractual maturity of the asset, adjusted for any expected prepayments.

For certain callable debt securities purchased at a premium, the amortization is recorded to the earliest call date. For mortgage and asset-backed securities, prepayment experience is evaluated monthly to determine if a change in a bond's estimated remaining life is necessary. A corresponding adjustment is then made in the related amortization of premium or discount accretion.

Other securities include Federal Reserve and Federal Home Loan Bank stock, which represent equity interests the Company is required to hold in the Federal Reserve Banks and Federal Home Loan Banks. These amounts are carried at cost as they do not have a readily determinable fair value because ownership of these shares is restricted, and they lack a market.

Purchases and sales of securities are recognized on a trade date basis. A receivable or payable is recognized for transactions pending settlements.

Allowance for Credit Losses on Available-for-Sale Debt Securities And Allowance for Credit Losses on Loans

Allowance for Credit Losses on Available-for-Sale Debt Securities

For AFS debt securities in an unrealized loss position, the entire loss in fair value is required to be recognized in current earnings if the Company intends to sell the securities or believes it more likely than not that it will be required to sell the security before the anticipated recovery. Any time the Company does not expect to recover the amortized cost basis, a credit loss is deemed to have occurred and an allowance for credit losses is recorded. The allowance for credit losses is limited by the amount that the fair value is less than the amortized cost basis.

All securities not issued or guaranteed by the U.S. government, its agencies, or sponsored enterprises are subject to a quarterly review to test for impairment. This process is intended to adequately test a range of credit and loss assumptions and does not rely primarily on credit ratings.

Changes in the allowance for credit losses are recorded as a provision for (or reversal of) credit losses on the consolidated statements of income. Losses are charged against the allowance for credit losses on securities when management believes the inability to collect an AFS security is confirmed or when either of the conditions regarding intent or requirement to sell is met.

Accrued interest receivable on available for sale debt securities is reported in other assets on the consolidated balance sheet. The Company has elected the practical expedient to exclude the accrued interest from all required disclosures of amortized cost of debt securities. Additionally, an election was made not to measure an allowance for credit losses for accrued interest receivables. Interest accrued but not received is reversed against interest income.

Allowance for Credit Losses on Loans

The allowance for credit losses on loans is a valuation amount that is deducted from the amortized cost basis of loans not held at fair value to present the net amount expected to be collected over the contractual term of the loans. The allowance reflects management’s best estimate of expected credit losses, considering portfolio segmentation, historical loss experience, current conditions, and reasonable and supportable forecasts. Management applies qualitative adjustments to model outputs when appropriate to address factors not fully captured by the quantitative models. An allowance will be created upon origination or acquisition of a loan and is updated at subsequent reporting dates. The methodology is applied consistently for each reporting period. Changes to the allowance for credit losses on loans resulting from periodic evaluations are recorded through increases or decreases to the credit loss expense for loans, which is recorded in provision for credit losses on the consolidated statements of income. Loans that are deemed to be uncollectible are charged off against the related allowance for credit losses on loans. The allowance for credit losses on loans is measured on a collective (pool) basis. Loans are aggregated into pools based on similar risk characteristics including borrower type, collateral type, and expected credit loss patterns. The Company maintains a policy to reverse accrued and unpaid interest when a loan is placed on non-accrual. Therefore, an allowance is not recorded for accrued interest.

Loans Held for Sale

Loans held for sale are accounted for at fair value pursuant to the fair value option permitted by ASC 825, Financial Instruments. The Company elected to take the fair value option for loans held for sale permitted by ASC 825, Financial Instruments beginning January 1, 2020. The fair value is based on secondary market prices for loans with similar characteristics, including an adjustment for embedded servicing value. Gains and losses from the changes in fair value are included in mortgage banking revenues. Deferred fees and costs related to these loans are recognized as part of the cost basis of the loan at the time it is sold. Interest income related to loans held for sale is accrued based on the principal amount outstanding and the loan's contractual interest rate.

Loans

For purposes of these financial statements, the loan portfolio collectively includes all loans and leases the Company holds for investment, hereinafter referred to as “loans.” Loans that the Company intends and has the ability to hold for the foreseeable future or until maturity or payoff are carried at amortized cost. Amortized cost represents the outstanding principal balance of loans, net of any deferred origination fees and related costs. The Company has elected to exclude all accrued interest receivable from the disclosures of amortized cost and has opted not to establish an allowance for credit losses related to accrued interest receivables.

Interest on loans is accrued and credited to income based on the principal amount outstanding, using primarily a simple interest calculation. Loan and commitment fees, net of associated costs, are deferred and amortized over the life of the loans, shown as an adjustment to interest income. The Company applies the straight-line method for amortization, which approximates the level yield method. Amortization does not anticipate loan prepayments, and any unamortized fees are recognized in full at the time of payoff.

The accrual of interest on loans is discontinued when, (a) in management’s judgment, the interest is uncollectible in the normal course of business; or (b) when they become 90 days or more past due, unless they are well‑secured and in the process of collection. When a loan is placed on non-accrual status, any interest previously accrued but not collected is reversed against current income, and the loan is charged off to the extent uncollectible. Principal and interest payments received on non-accrual loans are generally applied to principal. Interest is included in income only after all previous loan charge-offs have been recovered and is recorded only as received. The loan is returned to accrual status only when the borrower has brought all past-due principal and interest payments current and, in the opinion of management, has demonstrated the ability to make future payments of principal and interest as scheduled.

Loan Modifications and Borrower Financial Difficulty

The Company may renegotiate the terms of existing loans during the normal course of business. When modifications are made to the terms of an existing loan, the Company assesses whether a borrower is experiencing financial difficulty. This assessment is performed in accordance with ASC 326 and considers both quantitative and qualitative indicators. The Company considers delinquency status, cash flow capacity, collateral performance, and the borrower’s ability to obtain alternative financing at market terms. Loan modifications are subject to established credit approval and oversight processes.

Liability for Unfunded Lending Commitments

The Company’s accrual for credit risk associated with unfunded lending commitments is maintained at a level that is appropriate to cover estimated losses associated with credit instruments that are not currently recognized as assets such as loan commitments, standby letters of credit or guarantees that are not unconditionally cancellable by the bank. This accrual is included in other liabilities in the consolidated balance sheets with changes to the liability recorded through increases or decreases to the provision for credit losses on the consolidated statements of income. The methodology used to measure credit losses for unfunded lending commitments is the same as the methodology used for loans, however, the estimate of credit risk for unfunded lending commitments takes into consideration the likelihood that funding will occur. The liability for unfunded lending commitments excludes any exposures that are unconditionally cancellable by the Company.

Land, Buildings, and Equipment

Land, buildings, and equipment are stated at cost less accumulated depreciation. Depreciation is computed on the straight-line or declining balance method depending upon the type of asset. The Company generally assigns depreciable lives of 25-30 years for buildings; 15 years for building improvements; 15 years for land improvements; and 3-7 years for furniture, equipment, and software. Leasehold improvements are assigned depreciable lives of the shorter of the lease term or 15 years. Maintenance and repair costs are charged to expense as incurred. Major improvements are individually considered and are capitalized or expensed as the facts dictate.

Goodwill and Other Intangible Assets

Goodwill represents the excess of cost over equity in net assets of entities acquired. The Company accounts for goodwill in accordance with ASC 350, Intangibles – Goodwill and Other. Under ASC 350, goodwill and intangible assets that have indefinite useful lives are not amortized but rather tested at least annually for impairment. Intangible assets that have finite useful lives continue to be amortized over 7 to 20 years. The Company performs an annual qualitative evaluation of goodwill. Based on the results of this qualitative assessment, if the Company concludes it is more likely than not that a reporting unit's fair value is less than its carrying amount, a quantitative analysis is performed. If the fair value of a reporting unit is less than the carrying amount, an impairment has occurred and is measured as the amount by which the carrying amount exceeds the reporting unit's fair value. During 2025, the Company completed its annual qualitative impairment assessment and concluded that it was not more likely than not that the fair value of any of its reporting units was below its respective carrying amount. The Company has not recorded impairment resulting from goodwill impairment tests during the years ended December 31, 2025 and 2024.

Foreclosed Assets

Foreclosed assets represent property that has been repossessed following default on a loan. These assets primarily consist of commercial and residential real estate, as well as other non-real estate property such as automobiles. Upon foreclosure, the assets are initially recognized at fair value, less estimated costs to sell, with any necessary valuation adjustments reflected in the allowance for credit losses.

The fair value of foreclosed assets is generally determined based on independent appraisals, third-party price opinions, or internally developed pricing models. These fair value estimates are reviewed and updated periodically to help ensure they accurately reflect market conditions.

Subsequent declines in fair value below the carrying amount are recognized through valuation allowances, which may be reversed if future increases in fair value occur. Any adjustments to the carrying value, along with realized gains or losses on the sale of foreclosed assets, as well as net operating expenses related to these assets, are recorded within other expenses.

Income Taxes

The Company and its subsidiaries file a consolidated federal income tax return. State and local income tax returns are filed on a combined, consolidated, or separate return basis based upon each jurisdiction’s laws and regulations. Deferred tax assets and liabilities are recognized based upon the differences between the values of assets and liabilities as recognized in the financial statements and their related tax basis using enacted tax rates in effect for the year in which the differences are expected to be recovered or settled. The effect of changes in statutory tax rates on the measurement of deferred tax assets and liabilities is recognized through income tax expense in the period the change is enacted. A valuation allowance is provided when it is more likely than not that some portion of the entire deferred tax asset may not be realized.

Revenue Recognition

Revenue should be recognized to reflect the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Revenue from financial instruments, including revenue from loans and securities, is not included within this guidance. Noninterest revenue items that are subject to this guidance mainly include fees for bank card, trust, deposit account services, and consumer brokerage services and are discussed below and summarized in the table that follows.

Fees for Fiduciary Services

Trust and asset management income is primarily comprised of fees earned from the management and administration of trusts, settlement of estates, and other similar duties where Central Trust Company serves in a fiduciary capacity. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the average monthly value of the assets under management and the applicable fee rate or otherwise as negotiated as a fee for service. Other transactional-based services, including but not limited to, tax return preparation and financial planning are available. The performance obligation for these services is generally satisfied, and related revenue recognized, at the completion of the service.

Service Charges and Commissions

Service charges on deposit accounts consist of account analysis fees (i.e., net fees earned on analyzed business and public checking accounts), monthly service fees, check orders, and other deposit account related fees. The Company's performance obligation for account analysis and monthly service fees is generally satisfied, and the related revenue recognized, when the service is provided and received immediately or in the following month.

The Company provides corporate cash management services to its business customers to meet their various transaction processing needs. Such services include deposit and check processing, lockbox, remote deposit, reconciliation, online banking, and other similar transaction processing services. The Company maintains unit prices for each type of service, and the customer is billed based on transaction volumes processed monthly.

Overdraft fees are charged to customers when daily checks and other withdrawals to customers’ accounts exceed balances on hand. The daily overdraft charge is calculated and the fee is posted to the customer’s account each day.

Other deposit related fees such as check orders, foreign ATM processing fees, stop payment fees, and cashier’s checks are largely transactional based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, when the transaction is processed.

Payment Services Revenue

Payment services revenue includes bankcard transaction fees, exchange, and other service charges that are primarily comprised of debit and credit card income, ATM fees, merchant services income, and other service charges. Debit and credit card income is primarily comprised of interchange fees earned whenever the Company’s debit and credit cards are processed through card payment networks such as MasterCard. The fees earned are established by the settlement network and are dependent on the type of transaction processed but are typically based on a per unit charge. Interchange income is settled daily through the networks.

Brokerage Services

Brokerage services revenue is comprised of commissions received upon the execution of purchases and sales of mutual fund shares and equity securities, in addition to certain limited insurance products in an agency capacity. Also, fees are earned on managed advisory programs. Payment from the customer is upon settlement for purchases and sales of securities, upon purchase for annuities and insurance products, and upon inception of the service period for advisory programs.

Other Non-Interest Income from Contracts with Customers

Other non-interest income consists of gains on foreclosed assets, bank premises and equipment, official check fees, international currency commissions, and other miscellaneous consumer product fees. Performance obligations for these services consist mainly of the execution of transactions for the sale of various properties. Fees from these revenue sources are recognized when the performance obligation is completed, at which time cash is received by the Company.

Comprehensive Income

Comprehensive income is defined as the change in equity (net assets) of a business enterprise during a period from transactions and other events and circumstances from nonowner sources. For the Company, this includes net income, changes in unrealized gains and losses on AFS investment securities, and the net periodic benefit/cost related to the Company’s defined benefit pension plan, net of applicable tax effects. The amounts recognized in accumulated other comprehensive loss related to the defined benefit pension plan are adjusted out of accumulated other comprehensive loss when they are subsequently recognized as components of net periodic benefit cost.

Mortgage Banking

The fair value of retained mortgage servicing rights related to loans originated and sold is capitalized as an asset in accordance with ASC 860, Accounting for Servicing of Financial Assets, thereby increasing the gain on sale of the loan. Such mortgage servicing rights are amortized in proportion to and over the period of estimated net servicing income, considering appropriate prepayment assumptions. Any remaining unamortized amount is charged to expense if the related loan is repaid prior to maturity.

Management monitors the capitalized mortgage servicing rights on a disaggregated basis for impairment based on the fair value of those rights. Any impairment is recognized through a valuation allowance.

Derivative Financial Instruments

ASC 815, Derivatives and Hedging, establishes accounting and reporting standards for derivative instruments, including certain derivatives embedded in other contracts, and for hedging activities. In accordance with ASC 815, the Company records all derivative instruments at fair value on the consolidated balance sheets.

Mortgage Banking Derivatives: The Company’s mortgage banking operations involve the origination of mortgage loans under interest rate lock commitments that are intended for sale into the secondary market. IRLCs represent commitments to originate loans with interest rates determined prior to funding and are accounted for as derivatives. The Company generally does not enter into sales commitments for these loans at the time the IRLC is issued; instead, it commits to sell the loans after funding.

To economically hedge the interest rate risk associated with IRLCs and funded loans awaiting sale, the Company enters into free‑standing derivative instruments, primarily commitments to sell TBA mortgage‑backed securities. The value of TBA commitments generally moves inversely with fixed‑rate mortgage loan values, thereby providing an economic offset to changes in interest rates.

The Company also sells certain mortgage loans on a mandatory delivery basis and enters into short positions in mortgage‑backed securities to hedge interest rate exposure associated with these transactions. IRLCs and related derivative instruments are recorded at fair value in other assets or other liabilities, with changes in fair value recognized in mortgage banking revenues, net.

Customer Repurchase Agreements

The Company engages in customer transactions involving the sale of securities under agreements to repurchase as of a specified future date. Such repurchase agreements are considered collateralized financing transactions, not as a sale of the underlying securities. The obligation to repurchase assets sold is reflected as a liability in the consolidated balance sheet of the Company at the amount of cash received in the transaction. The fair value of collateral provided to a counterparty is monitored daily, and collateral is returned or provided by the Company in order to maintain full collateralization for these transactions.

Stock Based Compensation

The Company’s stock-based compensation plan, as detailed in "Note 11, Stock-Based Compensation,” to our consolidated financial statements is accounted for in accordance with the guidance set forth in ASC 718, Compensation—Stock Compensation. Specifically, the Company adheres to the provisions outlined in ASC 718-10-30-3 and ASC 718-10-35-2, which require the measurement of stock-based compensation based on the fair value of the awards granted at the grant date.

The fair value for restricted stock awards (RSAs) is based on the weighted average market price of the Company’s common stock during a specified period that is within 30 days before or 30 days after grant date, as determined by the Board of Directors in its sole discretion. The cost of stock-based compensation is recognized over the requisite service period, which is typically the vesting period, in accordance with the principles of ASC 718.

The Company recognizes stock-based compensation expense in the consolidated statements of income within “Salaries and Benefits.” The expense is recognized over the vesting period, with the total expense being adjusted for forfeitures only when they occur, in line with the policy outlined under ASC 718. Forfeitures are accounted for on an actual basis, and no estimated forfeitures are included in the initial measurement of compensation cost.

Treasury Stock

The Company accounts for treasury stock under the cost method, as outlined in ASC 505-30, Equity—Treasury Stock. Purchases of the Company’s common stock are recorded at cost, which includes all direct costs associated with the acquisition. When treasury stock is reissued, the carrying value of treasury stock is reduced based on the average cost basis of the shares held in treasury.

Income Per Share

The Company applies the two-class method for the computation of income per share, as prescribed by ASC 260, Earnings Per Share. The two-class method is an earnings allocation formula that determines income per share for common stock and for participating securities, according to dividends declared and participation rights in undistributed earnings.

The Company’s nonvested share-based awards vest based on the satisfaction of service conditions and are subject to forfeiture until such conditions are met. These nonvested share-based awards are not considered participating securities for the purpose of calculating income per share and as such do not participate in undistributed earnings. However, dividends or dividend equivalents declared or paid on nonvested share-based awards with forfeitable dividend rights are deducted from the income available to common stockholders. Such amounts reflect dividends that have been allocated to other-than-common stockholders and reduce the amount of income available for distribution to common stockholders.
