NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Note 1 – Summary of Significant Accounting Policies

Nature of Operations

First Financial Bankshares, Inc., a Texas corporation, (“Bankshares,” “Company,” “we” or “us”) is a financial holding company which owns all of the capital stock of one bank with 80 locations located in Texas as of September 30, 2023. The Company’s subsidiary bank is First Financial Bank, N.A. The Company’s primary source of revenue is providing loans and banking services to consumers and commercial customers in the market area in which First Financial Bank, N.A. is located. In addition, the Company also owns First Financial Trust & Asset Management Company, N.A., First Financial Insurance Agency, Inc. (inactive), First Technology Services, Inc., FB Investment Paris Fund, LLC, and FFB Portfolio Management, Inc.

Basis of Presentation

A summary of significant accounting policies of the Company and its subsidiaries applied in the preparation of the accompanying consolidated financial statements follows. The accounting principles followed by the Company and the methods of applying them are in conformity with both United States generally accepted accounting principles (“GAAP”) and prevailing practices of the banking industry.

The Company evaluated subsequent events for potential recognition through the date the consolidated financial statements were issued.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The Company’s significant estimates include its allowance for credit losses and its valuation of financial instruments.

Consolidation

The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly-owned. All significant intercompany accounts and transactions have been eliminated.

Stock Repurchase

On July 27, 2021, the Company’s Board of Directors authorized the repurchase of up to 5,000,000 common shares through July 31, 2023. On July 25, 2023, the Company's Board of Directors renewed the prior authorization through July 31, 2024. The stock repurchase plan authorizes management to repurchase and retire the stock at such time as repurchases and retirements are considered beneficial to the Company and stockholders. Any repurchase of stock will be made through the open market, block trades, or in privately negotiated transactions in accordance with applicable laws and regulations. Under the repurchase plan, there is no minimum number of shares that the Company is required to repurchase. Under the prior authorization, 244,559 shares were repurchased and retired (all during the months of June and July 2022) at an average price of $38.61 per share. Under the current authorization, the Company has repurchased and retired 101,337 shares (all during September 2023) at an average price of $26.99 per share.

Other Recently Issued and Effective Authoritative Accounting Guidance

ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” ASU 2020-04 provides optional expedients and exceptions for accounting related to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. ASU 2020-04 applies only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform and do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. ASU 2020-04 was effective upon issuance, and based upon the amendments provided in ASU 2022-06 discussed below, can generally be applied through December 31, 2024. The adoption of ASU 2020-04 did not have a significant impact on our financial statements.

ASU 2021-01, “Reference Rate Reform (Topic 848): Scope.” ASU 2021-01 clarifies that certain optional expedients and exceptions in ASC 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. ASU 2021-01 also amends the expedients and exceptions in ASC 848 to capture the incremental consequences of the scope clarification and to tailor the existing guidance to derivative instruments affected by the discounting transition. ASU 2021-01 was effective upon issuance, and based upon the amendments provided in ASU 2022-06 discussed below, can generally be applied through December 31, 2024. The adoption of ASU 2021-01 did not have a significant impact on our financial statements.

10

ASU 2022-02, "Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures." ASU 2022-02 eliminates the accounting guidance for troubled debt restructurings in ASC Subtopic 310-40, Receivables - Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. ASU 2022-02 will also require that an entity disclose current-period gross charge-offs by year of origination for financial receivables and net investment leases within the scope of ASC Subtopic 326-20, Financial Instruments - Credit Losses - Measured at Amortized Cost. ASU 2022-02 became effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, though early adoption is permitted. The adoption of ASU 2022-02 did not have a significant impact on our financial statements.

ASU 2022-06, "Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848." ASU 2022-06 extends the period of time preparers can utilize the reference rate reform relief guidance provided by ASU 2020-04 and ASU 2021-01, which are discussed above. ASU 2022-06, which was effective upon issuance, defers the sunset date of this prior guidance from December 31, 2022 to December 31, 2024, after which entities will no longer be permitted to apply the relief guidance in Topic 848. The adoption of ASU 2022-06 did not have a significant impact on our financial statements.

Investment Securities

Management classifies debt securities as held-to-maturity, available-for-sale, or trading based on its intent. Securities that management has the positive intent and ability to hold to maturity are classified as held-to-maturity and recorded at amortized cost, adjusted for amortization of premiums and accretion of discounts, which are recognized as adjustments to interest income using the interest method. Securities not classified as held-to-maturity or trading are classified as available-for-sale and recorded at fair value, with unrealized holding gains and losses (those for which no allowance for credit losses are recorded) reported as a component of other comprehensive income, net of tax. Management determines the appropriate classification of securities at the time of purchase.

Interest income includes amortization of purchase premiums and discounts over the period to maturity using a level-yield method, except for premiums on callable securities, which are amortized to their earliest call date. Realized gains and losses are recorded on the sale of securities in noninterest income.

The Company has made a policy election to exclude accrued interest from the amortized cost basis of securities and report accrued interest separately in other assets on the consolidated balance sheets. A security is placed on nonaccrual status at the time any principal or interest payments become more than 90 days delinquent or if full collection of interest or principal becomes uncertain. Accrued interest for a security placed on nonaccrual is reversed against interest income. There was no accrued interest related to securities reversed against interest income for the three and nine-months ended September 30, 2023 and 2022.

The Company records its available-for-sale securities portfolio at fair value. Fair values of these securities are determined based on methodologies in accordance with current authoritative accounting guidance. Fair values are volatile and may be influenced by a number of factors, including market interest rates, prepayment speeds, discount rates, credit ratings, and yield curves. Fair values for securities are based on quoted market prices, where available. If quoted market prices are not available, fair values are based on the quoted prices of similar instruments or an estimate of fair value by using a range of fair value estimates in the marketplace as a result of the illiquid market, specific to the type of security.

The Company’s investment portfolio currently consists of obligations of state and political subdivisions, mortgage pass-through securities, corporate bonds and general obligation or revenue based municipal bonds. Pricing for such securities is generally readily available and transparent in the market. The Company utilizes independent third-party pricing services to value its investment securities, which the Company reviews as well as the underlying pricing methodologies for reasonableness and to ensure such prices are aligned with pricing matrices. The Company validates prices supplied by the independent pricing services by comparison to prices obtained from other third-party sources on a quarterly basis.

Allowance for Credit Losses – Available-for-Sale Securities

For available-for-sale securities in an unrealized loss position, we first assess whether we intend to sell, or it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, any previously recognized allowances are charged-off and the security’s amortized cost basis is written down to fair value through income as a provision for credit losses. For available-for-sale securities that do not meet the aforementioned criteria, we evaluate whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis.

Management has made the accounting policy election to exclude accrued interest receivable on available-for-sale securities from the estimate of credit losses. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit losses. Available-for-sale securities are charged-off against the allowance or, in the absence of any allowance, written down through income when deemed uncollectible by management or when either of the aforementioned criteria regarding intent or requirement to sell is met.

At September 30, 2023 and 2022, and December 31, 2022, no allowance for credit losses - available-for-sale securities was recorded.

11

Allowance for Credit Losses – Held-to-Maturity Securities

The allowance for credit losses on held-to-maturity securities is a contra-asset valuation account, calculated in accordance with ASC 326, that is deducted from the amortized cost basis of held-to-maturity securities to present management’s best estimate of the net amount expected to be collected. Held-to-maturity securities are charged-off against the allowance when deemed uncollectible by management. Adjustments to the allowance are reported in our income statement as a component of credit loss expense. Management measures expected credit losses on held-to-maturity securities on a collective basis by major security type with each type sharing similar risk characteristics and considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. Management has made the accounting policy election to exclude accrued interest receivable on held-to-maturity securities from the estimate of credit losses.

At September 30, 2023 and 2022, and December 31, 2022, the Company held no securities that were classified as held-to-maturity.

Loans Held-for-Investment

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost, net of the allowance for credit losses. Amortized cost is the principal balance outstanding, net of purchase premiums and discounts, fair value hedge accounting adjustments, deferred loan fees and costs. The Company has made a policy election to exclude accrued interest from the amortized cost basis of loans and report accrued interest separately from the related loan balance in other assets on the condensed consolidated balance sheets.

Interest on loans is calculated by using the simple interest method on daily balances of the principal amounts outstanding. The Company defers and amortizes net loan origination fees and costs as an adjustment to yield.

Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Loans are placed on nonaccrual status when, in management’s opinion, the borrower may be unable to meet payment obligations as they become due, as well as when required by regulatory provisions. In determining whether or not a borrower may be unable to meet payment obligations for each class of loans, we consider the borrower’s debt service capacity through the analysis of current financial information, if available, and/or current information with regards to our collateral position. Regulatory provisions would typically require the placement of a loan on nonaccrual status if principal or interest has been in default for a period of 90 days or more unless the loan is both well secured and in the process of collection or full payment of principal and interest is not expected. Loans may be placed on nonaccrual status regardless of whether or not such loans are considered past due. When interest accrual is discontinued, all unpaid accrued interest is reversed. Interest income on nonaccrual loans is recognized only to the extent that cash payments are received in excess of principal due. A loan may be returned to accrual status when all the principal and interest amounts contractually due are brought current and future principal and interest amounts contractually due are reasonably assured.

Further information regarding our accounting policies related to past due loans, nonaccrual loans and loans to borrowers experiencing financial difficulty is presented in Note 3.

Acquired Loans

Loans acquired in connection with acquisitions are recorded at their acquisition-date fair value. The allowance for credit losses related to the acquired loan portfolio is not carried over. Upon the adoption of ASC 326, acquired loans are classified into two categories based on the credit risk characteristics of the underlying borrowers as either purchased credit deteriorated (“PCD”) loans, or loans with no evidence of credit deterioration (“non-PCD”).

PCD loans are defined as a loan or pool of loans that have experienced more-than-insignificant credit deterioration since the origination date. The Company uses a combination of individual and pooled review approaches to determine if acquired loans are PCD. At acquisition, the Company considers a number of factors to determine if an acquired loan or pool of loans has experienced more-than-insignificant credit deterioration.

The initial allowance related to PCD loans that share similar risk characteristics is established using a pooled approach. The Company uses either a discounted cash flow or weighted average remaining life method to determine the required level of the allowance. PCD loans that were classified as nonaccrual as of the acquisition date and are collateral dependent are assessed for allowance on an individual basis. For PCD loans, an initial allowance is established on the acquisition date. Subsequent to the acquisition date, the initial allowance for credit losses on PCD loans will increase or decrease based on future evaluations, with changes recognized in the provision for credit losses.

Non-PCD loans are pooled into segments together with originated loans that share similar risk characteristics and have an allowance established on the acquisition date, which is recognized in the current period provision for credit losses as well as a fair value adjustment to the amortized cost of the loan and accreted into income over the life of the loan.

Determining the fair value of the acquired loans involves estimating the principal and interest payment cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. Management considers a number of factors in evaluating the acquisition-date fair value including the remaining life, interest rate profile, market interest rate environment, payment schedules, risk ratings, probability of default and loss given default, and estimated prepayment rates. For PCD loans, the non-credit discount or premium is allocated to individual loans as determined by the difference between the loan’s unpaid principal balance and amortized cost basis. For non-PCD loans, the fair value discount or premium is allocated to individual loans and recognized into interest income on a level yield basis over the remaining expected life of the loan.

12

Allowance for Credit Losses - Loans

The allowance for credit losses (“allowance” or “ACL”) is a contra-asset valuation account, calculated in accordance with ASC 326, that is deducted from the amortized cost basis of loans. The ACL represents an amount which, in management’s judgement, is adequate to absorb the lifetime expected credit losses that may be experienced on outstanding loans at the balance sheet date based on the evaluation of the size and current risk characteristics of the loan portfolio, past events, current conditions, reasonable and supportable forecasts of future economic conditions and prepayment experience. The allowance for credit losses is measured and recorded upon the initial recognition of a financial asset. Determination of the adequacy of the allowance is inherently complex and requires the use of significant and highly subjective estimates. Loans are charged-off against the allowance when deemed uncollectible by management. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Adjustments to the allowance are reported in our income statement as a component of the provision for credit losses. Management has made the accounting policy election to exclude accrued interest receivable on loans from the estimate of credit losses.

The Company’s methodology for estimating the allowance includes: (1) a collective quantified reserve that reflects the Company’s historical default and loss experience adjusted for expected economic conditions throughout a reasonable and supportable period and the Company’s prepayment and curtailment rates; (2) collective qualitative factors that consider concentrations of the loan portfolio, expected changes to the economic forecasts, large relationships, early delinquencies, and factors related to credit administrations, including, among others, loan-to-value ratios, borrowers’ risk rating and credit score migrations; and (3) individual allowances on loans where borrowers are experiencing financial difficulty or when the Company determines that the foreclosure is probable.

In calculating the allowance for credit losses, most loans are segmented into pools based upon similar characteristics and risk profiles. Common characteristics and risk profiles include the type/purpose of loan, underlying collateral, geographical similarity and historical/expected credit loss patterns. In developing these loan pools for the purposes of modeling expected credit losses, we also analyzed the degree of correlation in how loans within each portfolio respond when subjected to varying economic conditions and scenarios as well as other portfolio stress factors. For modeling purposes, our loan portfolio segments include Commercial and Industrial (“C&I”), Municipal, Agricultural, Construction and Development, Farm, Non-Owner Occupied and Owner Occupied Commercial Real Estate (“CRE”), Residential, Consumer Auto, and Consumer Non-Auto. We periodically reassess each pool to ensure the loans within the pool continue to share similar characteristics and risk profiles and to determine whether further segmentation is necessary. Refer to Note 3 for more details on the Company’s portfolio segments.

The Company applies two methodologies to estimate the allowance on its pooled portfolio segments; discounted cash flows method and weighted average remaining life method. Allowance estimates on the following portfolio segments are calculated using the discounted cash flows method: C&I, Municipal, Construction and Development, Farm, Non-Owner Occupied and Owner Occupied CRE, and Residential. Allowance estimates on the following portfolio segments are calculated using the remaining life method: Agriculture, Consumer Auto and Consumer Non-Auto. The models related to these methodologies utilize the Company’s historical default and loss experience adjusted for future economic forecasts. The reasonable and supportable forecast period represents a one-year economic outlook for the applicable economic variables. Following the end of the reasonable and supportable forecast period, expected losses revert back to the historical mean over the next two years on a straight-line basis. Economic variables that have the most significant impact on the allowance include: Texas unemployment rate, Texas house price index, and Texas retail sales index. Contractual loan level cash flows within the discounted cash flows methodology are adjusted for the Company’s historical prepayment and curtailment rate experience.

In some cases, management may determine that an individual loan exhibits unique risk characteristics which differentiate the loan from other loans within our loan pools. In such cases, the loans are evaluated for expected credit losses on an individual basis and excluded from the collective evaluation. Specific allocations of the allowance for credit losses are determined by analyzing the borrower’s ability to repay amounts owed, collateral deficiencies, the relative risk rating of the loan and economic conditions affecting the borrower’s industry, among other things. A loan is considered to be collateral dependent when, based upon management’s assessment, the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the sale of the collateral. In such cases, expected credit losses are based on the fair value of the collateral at the measurement date, adjusted for estimated selling costs if satisfaction of the loan depends on the sale of the collateral. We reevaluate the fair value of collateral supporting collateral dependent loans on an ongoing basis.

Management qualitatively adjusts model results for risk factors that are not considered within our modeling processes but are nonetheless relevant in assessing the expected credit losses within our loan pools. These qualitative factor (“Q-Factor”) adjustments may increase or decrease management’s estimate of expected credit losses by a calculated percentage or amount based upon the estimated level of risk. The various risks that may be considered in making Q-Factor adjustments include, among other things, the impact of (i) changes in lending policies and procedures, including changes in underwriting standards and practices for collections, write-offs, and recoveries, (ii) actual and expected changes in national, regional, and local economic and business conditions and developments that affect the collectability of the loan pools, (iii) changes in the nature, volume and size of a loan or the loan pools and in the terms of the underlying loans, (iv) changes in the experience, ability, and depth of our lending management and staff, (v) changes in volume and severity of past due financial assets, the volume of nonaccrual assets, and the volume and severity of adversely classified or graded assets, (vi) changes in the quality of our credit review function, (vii) changes in the value of the underlying collateral for loans that are non-collateral dependent, (viii) the existence, growth, and effect of any concentrations of credit and (ix) other factors such as the regulatory, legal and technological environments, competition, and events such as natural disasters or health pandemics.

Management believes it uses relevant information available to make determinations about the allowance and that it has established the existing allowance in accordance with GAAP. However, the determination of the allowance requires significant judgment, and estimates of expected lifetime losses in the loan portfolio can vary significantly from the amounts actually observed. While management uses available information to recognize expected losses, future additions to the allowance may be necessary based on changes in the loans comprising the portfolio, changes in the current and forecasted economic conditions, changes to the interest rate environment which may directly impact prepayment and curtailment rate assumptions, and changes in the financial condition of borrowers.

13

Allowance for Credit Losses - Off-Balance-Sheet/Reserve for Unfunded Commitments

The allowance for credit losses on off-balance-sheet credit exposures is a liability account, calculated in accordance with ASC 326, representing expected credit losses over the contractual period for which we are exposed to credit risk resulting from a contractual obligation to extend credit. These obligations include unfunded lines of credit, commitments to extend credit and federal funds sold to correspondent banks and standby letters of credit. No allowance is recognized if we have the unconditional right to cancel the obligation. The allowance is reported as a component of accrued interest payable and other liabilities in our consolidated balance sheets. Adjustments to the allowance are reported in our income statement as a component of the provision for credit losses. At September 30, 2023 and 2022, and December 31, 2022, the Company’s reserve for unfunded commitments totaled $7,903,000, $10,879,000 and $12,323,000, respectively, which is included in other liabilities in the consolidated balance sheet.

Other Real Estate

Other real estate owned is foreclosed property held pending disposition and is initially recorded at fair value, less estimated costs to sell, and is included in other assets in the consolidated balance sheet. At foreclosure, if the fair value of the real estate, less estimated costs to sell, is less than the Company’s recorded investment in the related loan, a write-down is recognized through a charge to the allowance for credit losses. Any subsequent reduction in value is recognized by a charge to income. Operating and holding expenses of such properties, net of related income, and gains/losses on their disposition are included in net gain (loss) on sale of foreclosed assets as incurred.

Bank Premises and Equipment

Bank premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed principally on a straight-line basis over the estimated useful lives of the related assets. Leasehold improvements are amortized over the life of the respective lease or the estimated useful lives of the improvements, whichever is shorter.

Business Combinations, Goodwill and Other Intangible Assets

The Company accounts for all business combinations under the purchase method of accounting. Tangible and intangible assets and liabilities of the acquired entity are recorded at fair value. Intangible assets with finite useful lives represent the future benefit associated with the acquisition of the core deposits and are amortized over seven years, utilizing a method that approximates the expected attrition of the deposits. Goodwill with an indefinite life is not amortized, but rather tested annually for impairment as of June 30 each year. There was no impairment recorded during the nine-months ended September 30, 2023 or 2022, respectively.

Securities Sold Under Agreements to Repurchase

Securities sold under agreements to repurchase, which are classified as borrowings, generally mature within one to four days from the transaction date. Securities sold under agreements to repurchase are reflected at the amount of the cash received in connection with the transaction. The Company may be required to provide additional collateral based on the estimated fair value of the underlying securities.

Segment Reporting

The Company has determined that its banking regions meet the aggregation criteria of the current authoritative accounting guidance since each of its banking regions offer similar products and services, operate in a similar manner, have similar customers and report to the same regulatory authority, and therefore operate one line of business (community banking) located in a single geographic area (Texas).

Statements of Cash Flows

For purposes of reporting cash flows, cash and cash equivalents includes cash on hand, amounts due from banks, including interest-bearing deposits in banks with original maturity of 90 days or less, and federal funds sold.

Accumulated Other Comprehensive Earnings (Loss)

Unrealized net losses on the Company’s available-for-sale securities, net of applicable income taxes, totaled $639,934,000, $632,421,000 and $535,228,000 at September 30, 2023, and 2022, and December 31, 2022, respectively, are included in accumulated other comprehensive earnings (loss) as a separate component of shareholders' equity.

Income Taxes

The Company’s provision for income taxes is based on income before income taxes adjusted for permanent differences between financial reporting and taxable income. Deferred tax assets and liabilities are determined using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. As of September 30, 2023, and 2022, and December 31, 2022, deferred tax assets totaled $173,032,000, $168,398,000 and $145,511,000, respectively, and were included in other assets on the consolidated balance sheets.

14

Stock Based Compensation

The Company grants stock options for a fixed number of shares to employees with an exercise price equal to the fair value using the Black-Scholes model of the shares at the grant date. The grant date fair value is amortized over the vesting period which generally is three, five or six years. The Company also grants restricted stock and/or units for a fixed number of shares which generally vests over periods of one to three years, and performance stock units which vest over a 3-year period based on Company performance metrics relative to a defined peer group. For stock option grants, the exercise price is established based on the closing trading price. No adjustments have been necessary to properly value the grant based on the terms or other conditions of the grants. Expense is recognized based on the fair value of the portion of stock-based payment awards that ultimately expected to vest, reduced for forfeitures based on grant-date fair value. See Note 8 for further information.

Advertising Costs

Advertising costs are expensed as incurred.

Per Share Data

Net earnings per share (“EPS”) are computed by dividing net earnings by the weighted average number of common shares outstanding during the period. The Company calculates dilutive EPS assuming all outstanding stock options to purchase common shares and unvested restricted stock shares and units have been exercised and/or vested at the beginning of the year (or the time of issuance, if later.) The dilutive effect of the outstanding options and restricted stock is reflected by application of the treasury stock method, whereby the proceeds from the exercised options and unearned compensation for both restricted stock and stock options are assumed to be used to purchase common shares at the average market price during the respective period. There were 864,000 and 478,000 anti-dilutive shares for the three and nine-months ended September 30, 2023, respectively, that were excluded from the computation of EPS. There were 346,000 and 272,000 anti-dilutive shares for the three and nine-months ended September 30, 2022, respectively, that were excluded from the computation of EPS. The following table reconciles the computation of basic EPS to diluted EPS:

The Company did not hold any securities classified as held-to-maturity at September 30, 2023, September 30, 2022, or December 31, 2022.

The Company invests in mortgage-backed securities that have expected maturities that differ from their contractual maturities. These differences arise because borrowers may have the right to call or prepay obligations with or without a prepayment penalty. These securities include collateralized mortgage obligations (CMOs) and other asset backed securities. The expected maturities of these securities at September 30, 2023 and 2022, and December 31, 2022, were computed by using scheduled amortization of balances and historical prepayment rates.

The amortized cost and estimated fair value of available-for-sale securities at September 30, 2023, by contractual and expected maturity, are shown below (dollars in thousands):

	Amortized		Estimated
	Cost Basis		Fair Value
Due within one year	$	335,508	$	327,912

The number of investments in an unrealized loss position totaled 892 at September 30, 2023. We believe any unrealized losses in the U.S. treasury securities, obligations of state and political subdivisions, residential and commercial mortgage-backed and asset-backed investment securities, and corporate bonds and other at September 30, 2023 and 2022, and December 31, 2022, are due to changes in interest rates and not credit-related events. As such, no allowance for credit losses is required on these securities at September 30, 2023 and 2022, and December 31, 2022. Unrealized losses on investment securities are expected to recover over time as these securities approach maturity. Our mortgage related securities are backed by GNMA, FNMA and FHLMC or are collateralized by securities backed by these agencies. At September 30, 2023, 66.92% of our available-for-sale securities that are obligations of states and political subdivisions were issued within the State of Texas, of which 56.47% are guaranteed by the Texas Permanent School Fund.

Gross realized security losses from sales or calls during the third quarter of 2023 totaled $1,025,000. There were no gross realized security losses from sales or calls during the third quarter of 2022.

From a credit risk standpoint, the Company rates its loans in one of five categories: (i) pass, (ii) special mention, (iii) substandard, (iv) doubtful or (v) loss (which are charged-off).

23

The ratings of loans reflect a judgment about the risks of default and loss associated with the loan. The Company reviews the ratings on our credits as part of our ongoing monitoring of the credit quality of our loan portfolio. Ratings are adjusted to reflect the degree of risk and loss that are felt to be inherent in each credit as of each reporting period. Our methodology is structured so that specific allocations are increased in accordance with deterioration in credit quality (and a corresponding increase in risk and loss) or decreased in accordance with improvement in credit quality (and a corresponding decrease in risk and loss).

Credits rated special mention show clear signs of financial weaknesses or deterioration in credit worthiness, however, such concerns are not so pronounced that the Company generally expects to experience significant loss within the short-term. Such credits typically maintain the ability to perform within standard credit terms and credit exposure is not as prominent as credits rated more harshly.

Credits rated substandard are those in which the normal repayment of principal and interest may be, or has been, jeopardized by reason of adverse trends or developments of a financial, managerial, economic or political nature, or important weaknesses exist in collateral. A protracted workout on these credits is a distinct possibility. Prompt corrective action is therefore required to strengthen the Company’s position, and/or to reduce exposure and to assure that adequate remedial measures are taken by the borrower. Credit exposure becomes more likely in such credits and a serious evaluation of the secondary support to the credit is performed.

Credits rated doubtful are those in which full collection of principal appears highly questionable, and which some degree of loss is anticipated, even though the ultimate amount of loss may not yet be certain and/or other factors exist which could affect collection of debt. Based upon available information, positive action by the Company is required to avert or minimize loss. Credits rated doubtful are generally also placed on nonaccrual.

Modifications of receivables to debtors experiencing financial difficulty

On January 1, 2023, the Company adopted the accounting guidance in ASU 2022-02, which eliminates the recognition and measurement of a TDR. Due to the removal of the TDR designation, the Company evaluates all loan restructurings according to the accounting guidance for loan modifications to determine if the restructuring results in a new loan or a continuation of the existing loan. Loan modifications to borrowers experiencing financial difficulty that result in a direct change in the timing or amount of contractual cash flows include situations where there is principal forgiveness, term extensions, interest rate reduction, and combinations of the listed modifications. Therefore, the disclosures related to loan restructurings are only for modifications that directly affect cash flows.

An assessment of whether a borrower is experiencing financial difficulty is made on the date of a modification. Because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses due to the measurement methodologies used to estimate the allowance, a change to the allowance for credit losses is generally not recorded upon modification. During the nine-months ended September 30, 2023, loan modifications made to borrowers experiencing financial difficulty was insignificant.

Note 4 - Loans Held-for-Sale

Loans held-for-sale totaled $12,229,000, $18,815,000 and $11,965,000 at September 30, 2023 and 2022, and December 31, 2022, respectively. At September 30, 2023 and 2022, and December 31, 2022, $321,000, $2,923,000 and $1,468,000, respectively, are valued at the lower of cost or fair value, and the remaining amounts are valued under the fair value option.

These loans, which are sold on a servicing released basis, are valued using a market approach by utilizing either: (i) the fair value of the securities backed by similar mortgage loans, adjusted for certain factors to approximate the fair value of a whole mortgage loan, including the value attributable to mortgage servicing and credit risk, (ii) current commitments to purchase loans or (iii) recent observable market trades for similar loans, adjusted for credit risk and other individual loan characteristics. As these prices are derived from market observable inputs, the Company classifies these valuations as Level 2 in the fair value disclosures (see Note 9). Interest income on mortgage loans held-for-sale is recognized based on the contractual rates and reflected in interest income on loans in the consolidated statements of earnings. The Company has no continuing ownership in any residential mortgage loans sold.

The Company originates certain mortgage loans for sale in the secondary market. The mortgage loan sales contracts contain indemnification clauses should the loans default, generally in the first three to six months, or if documentation is determined not to be in compliance with regulations. The Company’s historic losses as a result of these indemnities have been insignificant.

Note 5 - Derivative Financial Instruments

The Company enters into interest rate lock commitments (“IRLCs”) with customers to originate residential mortgage loans at a specific interest rate that are ultimately sold in the secondary market. These commitments, which contain fixed expiration dates, offer the borrower an interest rate guarantee provided the loan meets underwriting guidelines and closes within the timeframe established by the Company.

The Company purchases forward mortgage-backed securities contracts to manage the changes in fair value associated with changes in interest rates related to a portion of the IRLCs. These instruments are typically entered into at the time the IRLC is made in the aggregate.

The fair values of IRLCs are based on current secondary market prices for underlying loans and estimated servicing value with similar coupons, maturity and credit quality, subject to the anticipated loan funding probability (pull-through rate) net of estimated costs to originate the loan. The fair value of IRLCs is subject to change primarily due to changes in interest rates and the estimated pull-through rate. These commitments are classified as Level 2 in the fair value disclosures (see Note 9), as the valuations are based on observable market inputs.

Forward mortgage-backed securities contracts are exchange-traded or traded within highly active dealer markets. In order to determine the fair value of these instruments, the Company utilizes the exchange price or dealer market price for the particular derivative contract and these instruments are therefore classified as Level 2 in the fair value disclosures (see Note 9). The estimated fair values are subject to change primarily due to changes in interest rates. The impact of these forward contracts is included in gain on sale and fees on mortgage loans in the statement of earnings.

These financial instruments are not designated as hedging instruments for accounting purposes. All derivatives are carried at fair value in either other assets or other liabilities and are reflected in the gain on sale and fees on mortgage loans in the consolidated statement of earnings.

The following tables provide the outstanding notional balances and fair values of outstanding derivative positions (dollars in thousands):

September 30, 2023:	Outstanding Notional Balance		Asset Derivative Fair Value		Liability Derivative Fair Value

Note 6 – Borrowings

Borrowings consisted of the following (dollars in thousands):

	September 30,				December 31,
	2023		2022		2022
Securities sold under agreements with customers to repurchase	$	621,791	$	749,278	$	618,829
Short-term borrowings		108,700		4,250		2,625
Other borrowings		21,053		21,053		21,053
Total	$	751,544	$	774,581	$	642,507

Securities sold under repurchase agreements are generally with significant customers of the Company that require short-term liquidity for their funds for which the Company pledges certain securities that have a fair value equal to at least the amount of the borrowings. The agreements mature daily and therefore the risk arising from a decline in the fair value of the collateral pledged is minimal. The securities pledged are mortgage-backed securities. These agreements do not include “right of set-off” provisions and therefore the Company does not offset such agreements for financial reporting purposes.

The Company renewed its loan agreement, effective June 30, 2023, with Frost Bank. Under the loan agreement, as renewed and amended, we are permitted to draw up to $25,000,000 on a revolving line of credit. There was no outstanding balance under the line of credit as of September 30, 2023.

During 2021, the Company began investing in qualifying Community Development Entities ("CDE") under the federal New Market Tax Credits ("NMTC") program. See Note 7 for further discussion of our activity and related balances on the consolidated balance sheets, including the $21,053,000 in other borrowings shown above.

Note 7 - Income Taxes

Income tax expense was $10,848,000 for the third quarter of 2023 as compared to $12,095,000 for the same period in 2022. The Company’s effective tax rates on pretax income were 17.96% and 16.93% for the third quarters of 2023 and 2022, respectively. Income tax expense was $34,291,000 for the nine-months ended September 30, 2023 as compared to $34,359,000 for the same period in 2022. The Company's effective tax rates on pretax income were 18.31% and 16.35% for the nine-months ended September 30, 2023 and 2022, respectively. The effective tax rates differ from the statutory federal tax rate of 21% primarily due to tax exempt interest income earned on certain investment securities and loans, the deductibility of dividends paid to our employee stock ownership plan, excess tax benefits for distributions under our deferred compensation plan and vesting of equity awards, and NMTC benefits.

Low Income Housing Tax Credit Investments - During 2021, the Company began investing in an affordable housing fund that will invest in real estate projects that qualify for the federal low-income housing tax credit ("LIHTC") program designed to promote private development of low income housing. The investments made by the fund will generate a return to the Company primarily through the realization of LIHTCs, and also through federal tax deductions generated from the ongoing operating losses from the investees of the fund. The Company's investment in the fund will be amortized through income tax expense using the proportional amortization method as related tax credits are utilized by the Company. The initial capital contribution commitment to the fund was for up to $5,500,000. Contributions were $539,000 at September 30, 2023, and $131,000 at September 30, 2022, and December 31, 2022, respectively, which is included in other assets on the consolidated balance sheet.

New Market Tax Credit Investments - During 2021, the Company began investing in qualifying CDEs under the federal NMTC program. NMTC investments are made through the third-party CDEs which are qualified through the U.S. Department of Treasury and receive periodic allocation of amounts under the NMTC program. NMTCs are generated from qualified investments by the CDEs utilizing equity investments made by a taxpayer, like the Company. Through these equity investments, the Company will receive the tax benefits from the NMTCs equal to 39% of the qualified investment from the CDE yield method and related tax credits are allocated to the Company. At September 30, 2023, September 30, 2022, and December 31, 2022, the consolidated balance sheet of the Company included a $18,000,000 loan to the investee in loans and the $21,053,000 leveraged loan from the investee in other borrowings (see Note 6). At September 30, 2023 and 2022, and December 31, 2022, the consolidated balance sheet of the Company included CDE investments in other assets of $26,009,000, $29,000,000, and $26,825,000, respectively.

Note 8 - Stock Based Compensation

On April 27, 2021, the Company’s shareholders approved the 2021 Omnibus Stock and Incentive Plan (“2021 Plan”) and reserved 2,500,000 shares of the Company’s common stock for issuance under this plan. At September 30, 2023, the Company had 1,562,362 shares of stock remaining for issuance under the plan. The 2021 Plan superseded all prior stock option and restricted stock plans with shares previously reserved for issuance under such plans cancelled.

Restricted Stock Units

Under the 2021 Plan, the Company grants restricted stock units under compensation arrangements for the benefit of employees, senior and executive officers and directors. Restricted stock unit grants are subject to time-based vesting. The total number of restricted stock units granted represents the maximum number of restricted stock units eligible to vest based upon the service conditions set forth in the grant agreements. The following table summarizes information about the changes in restricted stock units for the nine-months ended September 30, 2023 and 2022.

	For the Nine-Months Ended September 30,
	2023					2022
	Restricted Stock Units Outstanding			Weighted Average Grant Date Fair Value		Restricted Stock Units Outstanding			Weighted Average Grant Date Fair Value
Balance at beginning of period		39,657		$	47.83		22,597		$	48.91
Grants		33,294			29.53		24,833			47.19

Balance at end of period		55,510		$	36.81		39,657		$	47.83

Performance Stock Units

Also under the 2021 Plan, the Company awards performance-based restricted stock units (“PSUs”) to employees, senior and executive officers, and directors. Under the terms of the award, the number of units that will vest and convert to shares of common stock will be based on the extent to which the Company achieves specific performance criteria during the fixed three-year performance period. The number of shares issued upon vesting will range from 0% to 200% of the PSUs granted. The PSUs vest at the end of a three-year period based 50% each on average adjusted earnings per share growth and return on average assets as reported, adjusted for unusual gains/losses, merger expenses, and other items as approved by the compensation committee of the Company's board of directors. Performance for each period is measured relative to other U.S. publicly traded banks with $10 billion to $50 billion in assets. Compensation expense for the PSUs will be estimated each period based on the fair value of the stock at the grant date and the most probable outcome of the performance condition, adjusted for the passage of time within the vesting period of the awards.

The following table summarizes information about the changes in PSUs as of and for the nine-months ended September 30, 2023 and 2022.

	For the Nine-Months Ended September 30,
	2023					2022
	Performance-Based Restricted Stock Units Outstanding			Weighted Average Grant Date Fair Value		Performance-Based Restricted Stock Units Outstanding			Weighted Average Grant Date Fair Value
Balance at beginning of period		47,082		$	48.00		22,597		$	48.91

Restricted stock awards are subject to time-based vesting. The total number of restricted stock awards granted represents the maximum number of shares of restricted stock eligible to vest based upon the service conditions set forth in the grant agreements.

The following table summarizes information about vested and unvested restricted stock.

	For the Nine-Months Ended September 30,
	2023					2022
	Restricted Stock Outstanding			Weighted Average Grant Date Fair Value		Restricted Stock Outstanding			Weighted Average Grant Date Fair Value
Balance at beginning of period		24,813		$	36.21		46,598		$	35.75

Balance at end of period		31,216		$	28.25		37,925		$	34.94

The total fair value of restricted stock vested for the nine-months ended September 30, 2023 and 2022, was $940,000 and $1,363,000, respectively.

The Company recorded restricted stock unit, performance-based restricted stock unit and restricted stock award expense for employees of $483,000 and $370,000 for the three-months ended September 30, 2023 and 2022, respectively. The Company recorded restricted stock unit, performance-based restricted stock unit and restricted stock award expense for employees of $1,261,000 and $1,390,000 for the nine-months ended September 30, 2023 and 2022, respectively. The Company recorded director expense related to these restricted stock grants of $175,000 and $150,000, for the three-months ended September 30, 2023 and 2022, respectively. The Company recorded director expense related to these restricted stock grants of $492,000 and $481,000, for the nine-months ended September 30, 2023 and 2022, respectively.

As of September 30, 2023 and 2022, there were $3,998,000 and $4,105,000 respectively, of total unrecognized compensation cost related to unvested restricted stock, restricted stock units and performance-based restricted stock units which is expected to be recognized over a weighted-average period of 1.27 years and 1.23 years, respectively. At September 30, 2023 and 2022, and December 31, 2022, there was $107,000, $72,000 and $74,000, respectively, accrued in other liabilities related to dividends declared to be paid upon vesting.

Stock Option Plans

Prior to the approval of the 2021 Plan, the 2012 Incentive Stock Option Plan (the “2012 Plan”) provided for the granting of options to employees of the Company at prices not less than market value at the date of the grant. The 2012 Plan provided that options granted vest and are exercisable after two years from the date of grant and vest at a rate of 20% each year thereafter and have a 10-year term. The most recent grants from the 2021 Plan provided that 20% of the options granted vest and are exercisable after one year from the date of grant and the remaining options vest and are exercisable at a rate of 20% each year thereafter and have a 10-year term. Shares are issued under the 2012 Plan and the 2021 Plan from available authorized shares. An analysis of stock option activity for the nine-months ended September 30, 2023 is presented in the table and narrative below:​​​​​​​

	Shares			Weighted- Average Ex. Price
Outstanding, December 31, 2022		1,490,413		$	29.99
Granted		253,228			29.53
Exercised		(84,000	)		18.36
Cancelled		(50,535	)		42.90
Outstanding, September 30, 2023		1,609,106			30.12
Exercisable, September 30, 2023		938,924		$	24.96

The options outstanding at September 30, 2023 had exercise prices ranging between $15.43 and $48.91. Stock options have been adjusted retroactively for the effects of stock dividends and splits.

The Company grants incentive stock options for a fixed number of shares with an exercise price equal to the fair value of the shares at the date of grant to employees.

The Company recorded stock option expense totaling $391,000 and $360,000 for the three-months ended September 30, 2023 and 2022, respectively. The Company recorded stock option expense totaling $1,280,000 and $992,000 for the nine-months ended September 30, 2023 and 2022, respectively.

As of September 30, 2023, there was $5,746,000 of total unrecognized compensation cost related to unvested share-based compensation arrangements granted under the plans. That cost is expected to be recognized over a weighted-average period of 1.67 years. The total fair value of shares vested during the nine-months ended September 30, 2023 and 2022 was $2,110,000 and $1,747,000, respectively.

Note 9 - Fair Value Disclosures

The authoritative accounting guidance for fair value measurements defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability shall not be adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact, and (iv) willing to transact.

The authoritative accounting guidance requires the use of valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present amount on a discounted basis. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement costs). Valuation techniques should be consistently applied. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. In that regard, the authoritative guidance establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

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

•Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (for example, interest rates, volatilities, prepayment speeds, loss severities, credit risks and default rates) or inputs that are derived principally from or corroborated by observable market data by correlation or other means.

•Level 3 Inputs – Significant unobservable inputs that reflect an entity’s own assumptions that market participants would use in pricing the assets or liabilities.

A description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below.

In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date.

Securities classified as available-for-sale and trading are reported at fair value utilizing Level 1 and Level 2 inputs. For these securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include market spreads, cash flows, the United States Treasury yield curve, live trading levels, trade execution data, dealer quotes, market consensus prepayment speeds, credit information and the security’s terms and conditions, among other items.

See Notes 4 and 5 related to the determination of fair value for loans held-for-sale, IRLCs and forward mortgage-backed securities trades.

There were no transfers between Level 2 and Level 3 during the three and nine-months ended September 30, 2023 and 2022, and the year ended December 31, 2022.

The following table summarizes the Company’s gains on sale and fees of mortgage loans for the three and nine-months ended September 30, 2023 and 2022 (dollars in thousand):

	Three-Months Ended September 30,						Nine-Months Ended September 30,
	2023			2022			2023		2022

* This includes gains on loans held-for-sale carried under the fair value method and lower of cost or market.

No residential mortgage loans held-for-sale were 90 days or more past due or considered nonaccrual as of September 30, 2023, September 30, 2022, or December 31, 2022. No significant credit losses were recognized on mortgage loans held-for-sale for the three and nine-months ended September 30, 2023 and 2022.

Certain non-financial assets and non-financial liabilities measured at fair value on a nonrecurring basis include other real estate owned, goodwill and other intangible assets, and other non-financial long-lived assets. Non-financial assets measured at fair value on a non-recurring basis during the nine-months ended September 30, 2023 include other real estate owned which, subsequent to their initial transfer to other real estate owned from loans, were re-measured at fair value through a write-down included in gain (loss) on sale of foreclosed assets. During the reported periods, all fair value measurements for foreclosed assets utilized Level 2 inputs based on observable market data, generally third-party appraisals, or Level 3 inputs based on customized discounting criteria. These appraisals are evaluated individually and discounted as necessary due to the age of the appraisal, lack of comparable sales, expected holding periods of property or special use type of the property. Such discounts vary by appraisal based on the above factors but generally range from 5% to 25% of the appraised value. Re-evaluation of other real estate owned is performed at least annually as required by regulatory guidelines or more often if particular circumstances arise. There were no other real estate owned properties that were re-measured subsequent to their initial transfer to other real estate owned during the three and nine-months ended September 30, 2023 and 2022.

At September 30, 2023, other real estate owned totaled $15,000. At September 30, 2022 and December 31, 2022, the Company had no other real estate owned.

The Company is required under current authoritative accounting guidance to disclose the estimated fair value of their financial instrument assets and liabilities including those subject to the requirements discussed above. For the Company, as for most financial institutions, substantially all of its assets and liabilities are considered financial instruments. Many of the Company’s financial instruments, however, lack an available trading market as characterized by a willing buyer and willing seller engaging in an exchange transaction.

The estimated fair value amounts of financial instruments have been determined by the Company using available market information and appropriate valuation methodologies. However, considerable judgment is required to interpret data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize in a current market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.

In addition, reasonable comparability between financial institutions may not be likely due to the wide range of permitted valuation techniques and numerous estimates that must be made given the absence of active secondary markets for many of the financial instruments. This lack of uniform valuation methodologies also introduces a greater degree of subjectivity to these estimated fair values.

Cash and due from banks, federal funds sold, interest-bearing deposits in banks and accrued interest receivable and payable are liquid in nature and considered Levels 1 or 2 of the fair value hierarchy.

Financial instruments with stated maturities have been valued using a present value discounted cash flow with a discount rate approximating current market for similar assets and liabilities and are considered Levels 2 and 3 of the fair value hierarchy. Financial instrument liabilities with no stated maturities have an estimated fair value equal to both the amount payable on demand and the carrying value and are considered Level 1 of the fair value hierarchy.

The carrying value and the estimated fair value of the Company’s contractual off-balance-sheet unfunded lines of credit, loan commitments and letters of credit, which are generally priced at market at the time of funding, are not material.

The estimated fair values and carrying values of all financial instruments under current authoritative guidance were as follows (dollars in thousands).

Introduction

As a financial holding company, we generate most of our revenue from interest on loans and investments, trust fees, gain on sale of mortgage loans and service charges and fees on deposit accounts. Our primary source of funding for our loans and investments are deposits held by our bank subsidiary, First Financial Bank, N.A. Our largest expenses are salaries and related employee benefits. We measure our performance by calculating our return on average assets, return on average equity, regulatory capital ratios, net interest margin and efficiency ratio, which is calculated by dividing noninterest expense by the sum of net interest income on a tax equivalent basis and noninterest income.

The following discussion and analysis of operations and financial condition should be read in conjunction with the financial statements and accompanying footnotes included in Item 1 of this Form 10-Q as well as those included in the Company’s 2022 Annual Report on Form 10-K.

Critical Accounting Policies

We prepare consolidated financial statements based on generally accepted accounting principles (“GAAP”) and customary practices in the banking industry. These policies, in certain areas, require us to make significant estimates and assumptions.

We deem a policy critical if (i) the accounting estimate requires us to make assumptions about matters that are highly uncertain at the time we make the accounting estimate; and (ii) different estimates that reasonably could have been used in the current period, or changes in the accounting estimate that are reasonably likely to occur from period to period, would have a material impact on the financial statements.

We deem our most critical accounting policies to be (i) our allowance for credit losses and our provision for credit losses and (ii) our valuation of financial instruments. We have other significant accounting policies and continue to evaluate the materiality of their impact on our consolidated financial statements, but we believe these other policies either do not generally require us to make estimates and judgments that are difficult or subjective, or it is less likely they would have a material impact on our reported results for a given period. A discussion of (i) our allowance for credit losses and our provision for credit losses and (ii) our valuation of financial instruments is included in Note 1 to our Consolidated Financial Statements beginning on page 10.

Stock Repurchase

On July 27, 2021, the Company’s Board of Directors authorized the repurchase of up to 5 million common shares through July 31, 2023. On July 25, 2023, the Company's Board of Directors renewed the prior authorization through July 31, 2024.The stock repurchase plan authorizes management to repurchase and retire the stock at such time as repurchases are considered beneficial to the Company and its stockholders. Any repurchase of stock will be made through the open market, block trades or in privately negotiated transactions in accordance with applicable laws and regulations. Under the repurchase plan, there is no minimum number of shares that the Company is required to repurchase. Under the prior authorization, 244,559 shares were repurchased and retired (all during the months of June and July 2022) at an average price of $38.61 per share. Under the current authorization, the Company has repurchased and retired 101,337 shares (all during September 2023) at an average price of $26.99 per share.

Results of Operations

Performance Summary. Net earnings for the third quarter of 2023 were $49.56 million compared to earnings of $59.34 million for the third quarter of 2022. Diluted earnings per share was $0.35 for the third quarter of 2023 and $0.41 for the third quarter of 2022.

The return on average assets was 1.53% for the third quarter of 2023, as compared to 1.76% for the third quarter of 2022. The return on average equity was 14.51% for the third quarter of 2023 as compared to 17.31% for the third quarter of 2022.

Net earnings for the nine-months ended September 30, 2023 were $153.00 million compared to earnings of $175.81 million for the same period in 2022. Diluted earnings per share was $1.07 for the nine-months ended September 30, 2023, as compared to $1.23 for the same period in 2022.

The return on average assets was 1.59% for the nine-months ended September 30, 2023, as compared to 1.77% for the same period a year ago. The return on average equity was 15.22% for the nine-months ended September 30, 2023, as compared to 15.88% for the same period in 2022.

Net Interest Income. Net interest income is the difference between interest income on earning assets and interest expense on liabilities incurred to fund those assets. Our earning assets consist primarily of loans and investment securities. Our liabilities to fund those assets consist primarily of noninterest-bearing and interest-bearing deposits.

Tax-equivalent net interest income was $96.97 million for the third quarter of 2023, as compared to $106.96 million for the same period last year. The decrease in 2023 tax equivalent net interest income compared to 2022 was largely attributable to the increases in the rates paid on deposits and borrowings and a change in the mix of interest earning assets primarily derived from a decrease in taxable and tax-exempt investment securities offset by an increase in average loans. Average earning assets were $11.96 billion for the third quarter of 2023, as compared to $12.54 billion during the third quarter of 2022. The decrease of $578.99 million in average earning assets in 2023 when compared to 2022 was primarily a result of (i) a decrease in taxable investment securities of $609.82 million, (ii) a decrease in tax-exempt securities of $586.17 million, (iii) a decrease in short-term investments of $194.42 million, offset by (iv) the increase of average loans of $811.42 million, when compared to the three months ended September 30, 2022 average balances. Average interest-bearing liabilities were $7.88 billion for the third quarter of 2023, as compared to $7.77 billion in the same period in 2022. The yield on earning assets increased 89 basis points while the rate paid on interest-bearing liabilities increased 158 basis points for the third quarter of 2023 compared to the third quarter of 2022.

Tax-equivalent net interest income was $295.20 million for the nine-months ended September 30, 2023, as compared to $309.05 million for the same period last year. The decrease in 2023 tax equivalent net interest income compared to 2022 was largely attributable to the increases in the rates paid on deposits and borrowings and a change in the mix of interest earning assets primarily derived from a decrease in taxable and tax-exempt investment securities offset by an increase in average loans. Average earning assets were $12.03 billion for the nine-months ended September 30, 2023, as compared to $12.51 billion during same period last year. The decrease of $485.85 million in average earning assets in 2023 when compared to 2022 was primarily a result of (i) a decrease in tax-exempt securities of $722.51 million, (ii) the decrease of taxable securities of $560.81 million, (iii) a decrease in short-term investments of $130.68 million, offset by (iv) the increase of average loans of $928.16 million, when compared to the nine-months ended September 30, 2022 average balances. Average interest-bearing liabilities were $7.78 billion for the nine-months ended September 30, 2023, as compared to $7.74 billion for the nine-months ended September 30, 2022, respectively. The yield on earning assets increased 93 basis points while the rate paid on interest-bearing liabilities increased 146 basis points for the nine-months ended September 30, 2023 compared to the nine-months ended September 30, 2022.

The net interest margin, on a tax equivalent basis, was 3.22% for the third quarter of 2023, a decrease of 16 basis point from the same period in 2022. The net interest margin, on a tax equivalent basis, was 3.28% for the first nine-months of 2023, a decrease of two basis points from the same period in 2022. We continued to experience downward pressure on our net interest margin in 2023 compared to 2022 primarily due to (i) the effects of the Federal Reserve's accelerated rate of raising interest rates in 2022 and 2023, which was preceded by the extended period of historically low levels of short-term interest rates leading up to the first quarter of 2022, and (ii) the shift in the mix of interest-earning assets and interest-bearing deposits. The Federal Reserve began increasing interest rates by raising rates 25 basis points in March 2022, 50 basis points in May 2022, and 75 basis points in June, July, September and November 2022, respectively, 50 basis points in December 2022, and 25 basis points in February, March, May, and July 2023, respectively, resulting in a target rate range of 5.25% to 5.50% at September 30, 2023.

Loan rates on variable loans have increased as the majority of such loans are indexed to the applicable prime rate (currently 8.50% at September 30, 2023), subject to underlying floors. With the latest increase in the federal funds rate, the majority of variable rate loans have increased (see additional discussion beginning on page 49).

During 2022, we increased rates on each of the primary depository products in response to the increasing federal funds rate. Additionally, we have approximately $883 million of municipal and related deposits which are indexed to short-term treasury rates which have continued to increase with the changes in the applicable rate index. Average municipal and related deposits totaled $1.48 billion and $1.45 billion for the nine-months ended September 30, 2023 and 2022, respectively, with an average rate paid of 2.95% and 1.50%, for the respective nine-months then ended.

The net interest margin, which measures tax-equivalent net interest income as a percentage of average earning assets, is illustrated in Table 2.

Noninterest Income. Noninterest income for the third quarter of 2023 was $28.07 million compared to $30.94 million in the same quarter of 2022. Debit card fees for the third quarter of 2023 decreased by $546 thousand from the third quarter of 2022 due to the recognition of $988 thousand of volume incentive income in the third quarter of 2022 compared to $375 thousand in the third quarter of 2023. Mortgage related income was $3.44 million in the third quarter of 2023 compared to $4.07 million in the third quarter of 2022 due to lower overall origination volumes and margins on loan sales primarily because of the significant increase in mortgage interest rates. Available for sale securities totaling $113.13 million with an average book yield of 3.53% were sold in the third quarter of 2023 resulting in a loss on sales of securities of $972 thousand compared to a gain on sales of securities of $334 thousand in the third quarter of 2022.The proceeds from the sales of these securities are being used to fund organic loan growth that is yielding around 8%, resulting in an anticipated earn back period of less than six months.

Noninterest income for the nine-months ended September 30, 2023 was $86.03 million compared to $103.14 million in the same period in 2022. Debit card fees for the nine-months ended September 30, 2023 were $16.70 million compared to $24.38 million during the nine-months ended September 30, 2022 due to the impact of the Bank becoming subject to regulations imposed by the Federal Reserve that limits debit card interchange revenue (also known as the "Durbin Amendment") which became effective for the Company as of July 1, 2022, and is consistent with our previously disclosed expectations. Mortgage related income was $9.95 million in the nine-months ended September 30, 2023 compared to $16.13 million in the nine-months ended September 30, 2022 due to lower overall origination volumes and margins on loan sales as a result of the increases in mortgage interest rates. During the nine-months ended September 30, 2023, losses on sales of available-for-sale securities was $914 thousand, compared to a gain on sales of available-for-sale securities of $2.01 million during the same period in 2022. Net gain on sale of foreclosed assets was $23 thousand for the nine-months ended September 30, 2023, compared to $1.45 million for the same period in 2022. Recoveries of interest on previously charged-off or nonaccrual loans totaled $1.52 million for the nine-months ended September 30, 2023, compared with $2.60 million for the same period in 2022.

Debit card fees are charges that merchants pay to us and other card-issuing banks for processing electronic payment transactions. Debit card fees consist of income from debit card usage, point of sale income for debit card transactions and ATM service fees. Federal Reserve Board rules applicable to financial institutions that have assets of $10 billion or more provide that the maximum permissible interchange fee for an electronic debit transaction is limited to the sum of 21 cents per transaction plus 5 basis points multiplied by the value of the transaction. Based on the applicable Federal Reserve Board rules, the Company became subject to the limitation effective July 1, 2022, which reduced debit card fees in 2023 compared to 2022, as discussed above.

Noninterest Expense. Total noninterest expense for the third quarter of 2023 was $59.54 million, compared to $59.44 million for the same period of 2022. An important measure in determining whether a financial institution effectively manages noninterest expense is the efficiency ratio, which is calculated by dividing noninterest expense by the sum of net interest income on a tax-equivalent basis and noninterest income. Lower ratios indicate better efficiency since more income is generated with a lower noninterest expense total. Our efficiency ratio was 47.62% for the third quarter of 2023 compared to 43.10% for the same quarter in 2022.

Salaries, commissions and employee benefits for the third quarter of 2023 totaled $32.94 million, compared to $33.89 million for the same period in 2022. The net decrease reflected lower profit sharing expenses of $583 thousand and a $310 thousand decrease in mortgage salaries and incentive compensation expenses.

All other categories of noninterest expense for the third quarter of 2023 totaled $26.60 million, compared to $25.55 million in the same quarter a year ago. Noninterest expense, excluding salary related costs, for the three-months ended September 30, 2023 increased primarily due to increases in FDIC insurance premiums of $656 thousand due to the increased FDIC insurance base assessment rate effective January 1, 2023, compared to the three-months ended September 30, 2022.

Total noninterest expense for the first nine months of 2023 was $174.41 million, a decrease of $2.59 million, or 1.46%, as compared to the same period in 2022. Our efficiency ratio was 45.75% for the first nine months of 2023 compared to 42.94% for the same period in 2022.

Salaries, commissions and employee benefits for the first nine months of 2023 totaled $96.16 million, compared to $101.18 million for the same period in 2022. The net decrease reflected lower profit sharing expenses of $3.49 million, a $2.02 million decrease in mortgage salaries and incentive compensation expenses and a $1.02 million decrease in medical expenses, offset by annual merit-based and other market-based pay increases that were effective March 1, 2023.

All other categories of noninterest expense for the first nine months of 2023 totaled $78.25 million, compared to $75.82 million for the same period in 2022. Noninterest expense, excluding salary related costs, for the nine-months ended September 30, 2023 increased primarily due to increases in FDIC insurance premiums of $1.95 million due to the increased FDIC insurance base assessment rate effective January 1, 2023.

Of the $4.04 billion of variable interest rate loans shown above, loans totaling $1.6 billion mature or reprice over the next twelve months. Of this amount, approximately $1.4 billion will reprice immediately upon changes in the underlying index rate (primarily U.S. prime rate) with the remaining $188 million being subject to floors above or ceilings below the current index.

Asset Quality. Our loan portfolio is subject to periodic reviews by our centralized independent loan review group as well as periodic examinations by bank regulatory agencies. Loans are placed on nonaccrual status when, in the judgment of management, the collectability of principal or interest under the original terms becomes doubtful. Nonaccrual, past due 90 days or more and still accruing, and foreclosed assets were $39.70 million at September 30, 2023, as compared to $24.62 million at September 30, 2022 and $24.33 million at December 31, 2022. As a percent of loans held-for-investment and foreclosed assets, these assets were 0.57% at September 30, 2023, 0.39% at September 30, 2022, and 0.38% at December 31, 2022. As a percent of total assets, these assets were 0.31% at September 30, 2023, as compared to 0.19% at September 30, 2022 and December 31, 2022, respectively. We believe the level of these assets to be manageable and are not aware of any material classified credits not properly disclosed as nonperforming at September 30, 2023.

(1) With the adoption of ASU 2022-02, effective January 1, 2023, TDR accounting has been eliminated.

We record interest payments received on nonaccrual loans as reductions of principal. Prior to the loans being placed on nonaccrual, we recognized interest income on these loans of approximately $963 thousand for the year ended December 31, 2022. If interest on these loans had been recognized on a full accrual basis during the year ended December 31, 2022, such income would have been approximately $2.32 million. Such amounts for the 2023 and 2022 interim periods were not significant.

Allowance for Credit Losses. The allowance for credit losses is the amount we determine as of a specific date to be appropriate to absorb current expected credit losses on existing loans. For a discussion of our methodology, see our accounting policies in Note 1 to the Consolidated Financial Statements (unaudited).

The provision for loan losses of $3.82 million for the three-months ended September 30, 2023 is combined with the reversal of provision for unfunded commitments of $1.55 million and reported in the net aggregate of $2.28 million under the provision for credit losses in the consolidated statements of earnings for the three-months ended September 30, 2023. The provision for loan losses of $15.05 million for the nine-months ended September 30, 2023 is combined with the reversal of provision for unfunded commitments of $4.42 million and reported in the net aggregate of $10.63 million under the provision for credit losses in the consolidated statements of earnings for the nine-months ended September 30, 2023.

50

The provision for loan losses of $1.06 million for the three-months ended September 30, 2022 is combined with the provision for unfunded commitments of $2.16 million and reported in the aggregate of $3.22 million under the provision for credit losses in the consolidated statements of earnings for the three-months ended September 30, 2022. The provision for loan losses of $8.91 million for the nine-months ended September 30, 2022 is combined with the provision for unfunded commitments of $4.44 million and reported in the aggregate of $13.35 million under the provision for credit losses in the consolidated statements of earnings for the nine-months ended September 30, 2022.

As a percent of average loans, net loan charge-offs were 0.04% for the third quarter of 2023, as compared to net loan recoveries of 0.07% for the third quarter of 2022. As a percent of average loans, net loan charge-offs were 0.02% for the first nine months of 2023, as compared to net loan recoveries of 0.04% for the first nine months of 2022. The allowance for credit losses as a percent of loans held-for-investment was 1.28% as of September 30, 2023, as compared to 1.18% as of September 30, 2022 and December 31, 2022, respectively.

Interest-Bearing Demand Deposits in Banks. The Company had interest-bearing deposits in banks of $180.01 million at September 30, 2023 compared to $138.48 million at September 30, 2022 and $37.39 million at December 31, 2022, respectively. At September 30, 2023, interest-bearing deposits in banks included $179.18 million maintained at the Federal Reserve Bank of Dallas and $832 thousand on deposit with the FHLB.

Available-for-Sale Securities. At September 30, 2023, securities with a fair value of $4.65 billion were classified as securities available-for-sale. As compared to December 31, 2022, the available-for-sale portfolio at September 30, 2023 reflected (i) an increase of $2.90 million in U.S. Treasury securities, (ii) a decrease of $434.86 million in obligations of states and political subdivisions, and (iv) a decrease of $388.85 million in mortgage-backed securities, and (iv) a decrease of $1.01 million in corporate bonds and other securities. Fluctuations in the available-for-sale securities portfolio balances were primarily driven by sales, calls, and maturities, and changes in unrealized losses during the first nine months of 2023. Our mortgage related securities are backed by GNMA, FNMA or FHLMC or are collateralized by securities backed by these agencies.

See the below table and Note 2 to the Consolidated Financial Statements (unaudited) for additional disclosures relating to the maturities and fair values of the investment portfolio at September 30, 2023 and 2022, and December 31, 2022.

All yields are computed on a tax-equivalent basis assuming a marginal tax rate of 21%. Yields on available-for-sale securities are based on amortized cost. Maturities of mortgage-backed securities are based on contractual maturities and could differ due to prepayments of underlying mortgages. Maturities of other securities are reported at the earlier of maturity date or call date.

As of September 30, 2023, the investment portfolio had an overall tax equivalent yield of 2.22%, a weighted average life of 7.94 years and modified duration of 6.42 years.

The estimated amount of uninsured and uncollateralized deposits including related accrued and unpaid interest is approximately $5.16 billion as of September 30, 2023.

Borrowings. Included in borrowings were federal funds purchased, securities sold under repurchase agreements, advances from the FHLB and other borrowings of $751.54 million, $774.58 million and $642.51 million at September 30, 2023 and 2022, and December 31, 2022, respectively. Securities sold under repurchase agreements are generally with significant customers of the Company that require short-term liquidity for their funds for which we pledge certain securities that have a fair value equal to at least the amount of the short-term borrowings. The average balance of federal funds purchased, securities sold under repurchase agreements, advances from the FHLB and other borrowings were $621.19 million and $768.10 million in the third quarters of 2023 and 2022, respectively. The weighted average interest rates paid on these borrowings were 3.22% and 0.40% for the third quarters of 2023 and 2022, respectively. The average balance of federal funds purchased, securities sold under repurchase agreements, advances from the FHLB and other borrowings were $653.78 million and $759.91 million for the nine-months ended September 30, 2023 and 2022, respectively. The weighted average interest rates paid on these borrowings were 2.85% and 0.21% for the nine-months ended September 30, 2023 and 2022, respectively.

Interest Rate Risk

Interest rate risk results when the maturity or repricing intervals of interest-earning assets and interest-bearing liabilities are different. Our exposure to interest rate risk is managed primarily through our strategy of selecting the types and terms of interest-earning assets and interest-bearing liabilities that generate favorable earnings while limiting the potential negative effects of changes in market interest rates. We use no off-balance-sheet financial instruments to manage interest rate risk.

Our subsidiary bank has an asset liability management committee that monitors interest rate risk and compliance with investment policies. The subsidiary bank utilizes an earnings simulation model as the primary quantitative tool in measuring the amount of interest rate risk associated with changing market rates. The model quantifies the effects of various interest rate scenarios on projected net interest income and net income over the next twelve months. The model measures the impact on net interest income relative to a base case scenario of hypothetical fluctuations in interest rates over the next twelve months. These simulations incorporate assumptions regarding balance sheet growth and mix, pricing and the re-pricing and maturity characteristics of the existing and projected balance sheet.

52

The following analysis depicts the estimated impact on net interest income of immediate changes in interest rates at the specified levels for the periods presented.

	Percentage change in net interest income:
Change in interest rates:	September 30,		December 31,
(in basis points)	2023	2022	2022
+400	3.03%	6.87%	5.13%
+300	2.23%	5.24%	3.86%
+200	1.82%	3.90%	3.13%
+100	1.14%	2.30%	2.09%
-100	(1.76)%	(2.80)%	(2.66)%
-200	(3.45)%	(5.62)%	(5.47)%
-300	(5.76)%	(8.51)%	(8.54)%
-400	(6.31)%	(9.82)%	(10.31)%

The results for the net interest income simulations as of September 30, 2023 and 2022, and December 31, 2022 resulted in an asset sensitive position. These are good faith estimates and assume that the composition of our interest sensitive assets and liabilities existing at each year-end will remain constant over the relevant twelve-month measurement period and that changes in market interest rates are instantaneous and sustained across the yield curve regardless of duration of pricing characteristics on specific assets or liabilities. Also, this analysis does not contemplate any actions that we might undertake in response to changes in market interest rates. We believe these estimates are not necessarily indicative of what actually could occur in the event of immediate interest rate increases or decreases of this magnitude. As interest-bearing assets and liabilities reprice in different time frames and proportions to market interest rate movements, various assumptions must be made based on historical relationships of these variables in reaching any conclusion. Since these correlations are based on competitive and market conditions, we anticipate that our future results will likely be different from the foregoing estimates, and such differences could be material.

Should we be unable to maintain a reasonable balance of maturities and repricing of our interest-earning assets and our interest-bearing liabilities, we could be required to dispose of our assets in an unfavorable manner or pay a higher than market rate to fund our activities. Our asset liability management committee oversees and monitors this risk.

The fair value of our investment securities classified as available-for-sale totaled $4.65 billion at September 30, 2023. During the nine months ended September 30, 2023, the corresponding unrealized loss before taxes on the portfolio of $677.99 million at December 31, 2022, changed to an unrealized loss before taxes of $810.65 million at September 30, 2023, which is recorded net of taxes in accumulated other comprehensive earnings (loss) in shareholders' equity. The unrealized gains or losses, net of taxes, on the portfolio are excluded from the calculation of all regulatory capital ratios. The changes in the fair value were driven by changes in interest rates based on expected actions by the Federal Reserve Board and other market conditions. The overall valuation of the portfolio is most correlated to the 5-year U.S. Treasury rates based on the composition and duration of the portfolio. At September 30, 2023, the 5-year U.S. Treasury rate was 4.60% compared to 4.01% at December 31, 2022, representing a 59 basis point increase during the first nine months of 2023. As of September 30, 2023, an increase of 100 basis points in the 5-year U.S. Treasury rate would result in an increase to unrealized losses by approximately $258 million before taxes, while a 100 basis point decrease in the same rate would result in a decrease to unrealized losses by approximately $246 million before taxes. We believe that we have the ability to hold these securities based on our overall liquidity and intent to hold the portfolio.

Capital and Liquidity

Capital. We evaluate capital resources by our ability to maintain adequate regulatory capital ratios to do business in the banking industry. Issues related to capital resources arise primarily when we are growing at an accelerated rate but not retaining a significant amount of our profits or when we experience significant asset quality deterioration.

Total shareholders’ equity was $1.24 billion, or 9.71% of total assets at September 30, 2023, as compared to $1.13 billion, or 8.64% of total assets at September 30, 2022, and $1.27 billion, or 9.76% of total assets at December 31, 2022. Included in shareholders' equity at September 30, 2023, and 2022, and December 31, 2022 were $639.93 million, $632.42 million and $535.23 million, respectively, in unrealized losses on investment securities available-for-sale, net of related income taxes, although such amount is excluded from and does not impact regulatory capital. For the third quarter of 2023, total shareholders’ equity averaged $1.36 billion, or 10.58% of average assets, as compared to $1.36 billion, or 10.17% of average assets, during the same period in 2022. For the first nine months of 2023, total shareholders’ equity averaged $1.34 billion, or 10.44% of average assets, as compared to $1.48 billion, or 11.12% of average assets, during the same period in 2022.

Banking regulators measure capital adequacy by means of the risk-based capital ratios and the leverage ratio under the Basel III rules and prompt corrective action regulations. The risk-based capital rules provide for the weighting of assets and off-balance-sheet commitments and contingencies according to prescribed risk categories. Regulatory capital is then divided by risk-weighted assets to determine the risk-adjusted capital ratios. The leverage ratio is computed by dividing shareholders’ equity less intangible assets by quarter-to-date average assets less intangible assets.

Beginning in January 2015, under the Basel III rules, the implementation of the capital conservation buffer was effective for the Company starting at the 0.625% level and increasing 0.625% each year thereafter, until it reached 2.50% on January 1, 2019. As of January 1, 2019, the capital conservation buffer Basel III was fully phased in. The capital conservation buffer is designed to absorb losses during periods of economic stress and requires increased capital levels for the purpose of capital distributions and other payments. Failure to meet the amount of the buffer will result in restrictions on the Company’s ability to make capital distributions, including dividend payments and stock repurchases, and to pay discretionary bonuses to executive officers.

53

As of September 30, 2023 and 2022, and December 31, 2022, we had a total risk-based capital ratio of 19.49%, 19.07% and 19.29%, a Tier 1 capital to risk-weighted assets ratio of 18.35%, 18.03% and 18.22%; a common equity Tier 1 to risk-weighted assets ratio of 18.35%, 18.03% and 18.22% and a Tier 1 leverage ratio of 12.00%, 10.79% and 10.96%, respectively. The regulatory capital ratios as of September 30, 2023 and 2022, and December 31, 2022 were calculated under Basel III rules.

The regulatory capital ratios of the Company and Bank under the Basel III regulatory capital framework are as follows:

In connection with the adoption of the Basel III regulatory capital framework, our subsidiary bank made the election to continue to exclude accumulated other comprehensive income from available-for-sale securities (“AOCI”) from capital in connection with its quarterly financial filing and, in effect, to retain the AOCI treatment under the prior capital rules.

Liquidity. Liquidity is our ability to meet cash demands as they arise. Such needs can develop from loan demand, deposit withdrawals or acquisition opportunities. Potential obligations resulting from the issuance of standby letters of credit and commitments to fund future borrowings to our loan customers are other factors affecting our liquidity needs. Many of these obligations and commitments are expected to expire without being drawn upon;

54

therefore, the total commitment amounts do not necessarily represent future cash requirements affecting our liquidity position. The potential need for liquidity arising from these types of financial instruments is represented by the contractual notional amount of the instrument. Asset liquidity is provided by cash and assets which are readily marketable, or which will mature in the near future. Liquid assets include cash, federal funds sold, and short-term investments in time deposits in banks. Liquidity is also provided by access to funding sources, which include core depositors and correspondent banks that maintain accounts with and sell federal funds to our subsidiary bank. Other sources of funds include our ability to borrow from short-term sources, such as purchasing federal funds from correspondent banks, sales of securities under agreements to repurchase and other borrowings (see below) and an unfunded $25.00 million revolving line of credit established with Frost Bank, a nonaffiliated bank, which matures on June 30, 2025 (see next paragraph). Our subsidiary bank also has federal funds purchased lines of credit with two non-affiliated banks totaling $130.00 million. At September 30, 2023, there were no amounts drawn on these lines of credit. Our subsidiary bank also has (i) an available line of credit with the FHLB totaling $2.54 billion at September 30, 2023, secured by portions of our loan portfolio and certain investment securities, and (ii) access to the Federal Reserve Bank of Dallas lending program, including the Bank Term Funding Program, secured by portions of certain investment securities. At September 30, 2023, there was $45 million used on the FHLB line advance for undisbursed commitments (letters of credit) used to secure public funds and $100 million in overnight borrowings at the Federal Reserve Bank discount window.

The Company renewed its loan agreement, effective June 30, 2023, with Frost Bank. Under the loan agreement, as renewed and amended, we are permitted to draw up to $25.00 million on a revolving line of credit. Prior to June 30, 2025, interest is paid quarterly at The Wall Street Journal Prime Rate and the line of credit matures June 30, 2025. If a balance exists at June 30, 2025, the principal balance converts to a term facility payable quarterly over five years and interest is paid quarterly at The Wall Street Journal Prime Rate. The line of credit is unsecured. Among other provisions in the credit agreement, we must satisfy certain financial covenants during the term of the loan agreement, including, without limitation, covenants that require us to maintain certain capital, loan loss reserve, non-performing asset and cash flow coverage ratios. In addition, the credit agreement contains certain operational covenants, which among others, restricts the payment of dividends above 55% of consolidated net income, limits the incurrence of debt (excluding any amounts acquired in an acquisition) and prohibits the disposal of assets except in the ordinary course of business. Since 1995, we have historically declared dividends as a percentage of our consolidated net income in a range of 36% (low) in 2021 and 2020 to 53% (high) in 2003 and 2006. The Company was in compliance with the financial and operational covenants at September 30, 2023. There was no outstanding balance under the line of credit as of September 30, 2023.

In addition, we anticipate that future acquisitions of financial institutions, expansion of branch locations or offerings of new products could also place a demand on our cash resources. Available cash and cash equivalents at our parent company which totaled $133.90 million at September 30, 2023, investment securities which totaled $2.12 million at September 30, 2023 and mature over 6 to 7 years, available dividends from our subsidiaries which totaled $375.18 million at September 30, 2023, utilization of available lines of credit, and future debt or equity offerings are expected to be the source of funding for these potential acquisitions or expansions.

Our liquidity position is continuously monitored and adjustments are made to the balance between sources and uses of funds as deemed appropriate. Liquidity risk management is an important element in our asset/liability management process. We regularly model liquidity stress scenarios to assess potential liquidity outflows or funding problems resulting from economic disruptions, volatility in the financial markets, unexpected credit events or other significant occurrences deemed potentially problematic by management. These scenarios are incorporated into our contingency funding plan, which provides the basis for the identification of our liquidity needs. As of September 30, 2023, management is not aware of any events that are reasonably likely to have a material adverse effect on our liquidity, capital resources or operations. We are monitoring closely the impact to the financial system due to the recent failures of several banks. Given the diversified core deposit base and relatively low loan to deposit ratios maintained at our subsidiary bank, we consider our current liquidity position to be adequate to meet our short-term and long-term liquidity needs. In addition, management is not aware of any regulatory recommendations regarding liquidity that would have a material adverse effect on us.

Off-Balance Sheet (“OBS”)/Reserve for Unfunded Commitments. We are a party to financial instruments with OBS risk in the normal course of business to meet the financing needs of our customers. These financial instruments include unfunded lines of credit, commitments to extend credit and federal funds sold to correspondent banks and standby letters of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in our consolidated balance sheets. At September 30, 2023, the Company’s reserve for unfunded commitments totaled $7.90 million which is recorded in other liabilities.

Our exposure to credit loss in the event of nonperformance by the counterparty to the financial instrument for unfunded lines of credit, commitments to extend credit and standby letters of credit is represented by the contractual notional amount of these instruments. We generally use the same credit policies in making commitments and conditional obligations as we do for on-balance-sheet instruments.

Unfunded lines of credit and commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. These commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. We evaluate each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, as we deem necessary upon extension of credit, is based on our credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, property, plant, and equipment and income-producing commercial properties.

Standby letters of credit are conditional commitments we issue to guarantee the performance of a customer to a third party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The average collateral value held on letters of credit usually exceeds the contract amount.

Table 10 – Commitments as of September 30, 2023 (dollars in thousands):

	Total Notional Amounts Committed
Unfunded lines of credit	$	1,179,616
Unfunded commitments to extend credit		748,354
Standby letters of credit		55,632
Total commercial commitments	$	1,983,602

We believe we have no other OBS arrangements or transactions with unconsolidated, special purpose entities that would expose us to liability that is not reflected on the face of the financial statements. The above table does not include balances related to the Company’s IRLC and forward mortgage-backed security trades. Total commercial commitments were $1.98 billion at September 30, 2023, compared to $2.00 billion at September 30, 2022, and $2.06 billion at December 31, 2022.

Parent Company Funding. Our ability to fund various operating expenses, dividends, and cash acquisitions is generally dependent on our own earnings (without giving effect to our subsidiaries), cash reserves and funds derived from our subsidiaries. These funds historically have been produced by intercompany dividends and management fees that are limited to reimbursement of actual expenses. We anticipate that our recurring cash sources will continue to include dividends and management fees from our subsidiaries. At September 30, 2023, $375.18 million was available for the payment of intercompany dividends by our subsidiaries without the prior approval of regulatory agencies. Our subsidiaries paid aggregate dividends of $97.50 million and $67.50 million for the nine-months ended September 30, 2023 and 2022, respectively.

Dividends. Our long-term dividend policy is to pay cash dividends to our shareholders of approximately 35% to 40% of annual net earnings while maintaining adequate capital to support growth. We are also restricted by a loan covenant within our line of credit agreement with Frost Bank to dividend no greater than 55% of net income, as defined in such loan agreement. The cash dividend payout ratios have amounted to 49.48% and 39.78% of net earnings for the first nine months of 2023 and 2022, respectively. Given our current capital position, projected earnings and asset growth rates, we do not anticipate any significant change in our current dividend policy. In July 2023, the Board of Directors declared an $0.18 per share cash dividend for the third quarter of 2023, a 5.88% increase over the dividend declared in the third quarter of 2022. The record date for this dividend was September 14, 2023, payable on October 2, 2023.

Our bank subsidiary, which is a national banking association and a member of the Federal Reserve System, is required by federal law to obtain the prior approval of the OCC to declare and pay dividends if the total of all dividends declared in any calendar year would exceed the total of (i) such bank’s net profits (as defined and interpreted by regulation) for that year plus (ii) its retained net profits (as defined and interpreted by regulation) for the preceding two calendar years, less any required transfers to surplus.

To pay dividends, we and our subsidiary bank must maintain adequate capital above regulatory guidelines and comply with the general requirements applicable to a Texas corporation. Generally, a Texas corporation may not pay a dividend to its shareholders if (i) after giving effect to the dividend, the corporation would be insolvent, or (ii) the amount of the dividend would exceed the surplus of the corporation. In addition, if the applicable regulatory authority believes that a bank under its jurisdiction is engaged in or is about to engage in an unsafe or unsound practice (which, depending on the financial condition of the bank, could include the payment of dividends), the authority may require, after notice and hearing, that such bank cease and desist from the unsafe practice. The Federal Reserve, the FDIC and the OCC have each indicated that paying dividends that deplete a bank’s capital base to an inadequate level would be an unsafe and unsound banking practice. The Federal Reserve, the OCC and the FDIC have issued policy statements that recommend that bank holding companies and insured banks should generally only pay dividends out of current operating earnings.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Management considers interest rate risk to be a significant market risk for the Company. See “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations — Interest Rate Risk” for disclosure regarding this market risk.

Item 4. Controls and Procedures.

As of September 30, 2023, we carried out an evaluation, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) or 15d-15(e) of the Securities Exchange Act of 1934). Our management, which includes our principal executive officer and our principal financial officer, does not expect that our disclosure controls and procedures will prevent all errors and all fraud.

A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. Our principal executive officer and principal financial officer have concluded, based on our evaluation of our disclosure controls and procedures, that our disclosure controls and procedures were effective at the reasonable assurance level as of September 30, 2023.

Subsequent to our evaluation, there were no significant changes in internal controls over financial reporting or other factors that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Note 1 – Summary of Significant Accounting Policies

Nature of Operations

First Financial Bankshares, Inc., a Texas corporation, (“Bankshares,” “Company,” “we” or “us”) is a financial holding company which owns all of the capital stock of one bank with 80 locations located in Texas as of September 30, 2023. The Company’s subsidiary bank is First Financial Bank, N.A. The Company’s primary source of revenue is providing loans and banking services to consumers and commercial customers in the market area in which First Financial Bank, N.A. is located. In addition, the Company also owns First Financial Trust & Asset Management Company, N.A., First Financial Insurance Agency, Inc. (inactive), First Technology Services, Inc., FB Investment Paris Fund, LLC, and FFB Portfolio Management, Inc.

Basis of Presentation

A summary of significant accounting policies of the Company and its subsidiaries applied in the preparation of the accompanying consolidated financial statements follows. The accounting principles followed by the Company and the methods of applying them are in conformity with both United States generally accepted accounting principles (“GAAP”) and prevailing practices of the banking industry.

The Company evaluated subsequent events for potential recognition through the date the consolidated financial statements were issued.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The Company’s significant estimates include its allowance for credit losses and its valuation of financial instruments.

Consolidation

The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly-owned. All significant intercompany accounts and transactions have been eliminated.

Stock Repurchase

On July 27, 2021, the Company’s Board of Directors authorized the repurchase of up to 5,000,000 common shares through July 31, 2023. On July 25, 2023, the Company's Board of Directors renewed the prior authorization through July 31, 2024. The stock repurchase plan authorizes management to repurchase and retire the stock at such time as repurchases and retirements are considered beneficial to the Company and stockholders. Any repurchase of stock will be made through the open market, block trades, or in privately negotiated transactions in accordance with applicable laws and regulations. Under the repurchase plan, there is no minimum number of shares that the Company is required to repurchase. Under the prior authorization, 244,559 shares were repurchased and retired (all during the months of June and July 2022) at an average price of $38.61 per share. Under the current authorization, the Company has repurchased and retired 101,337 shares (all during September 2023) at an average price of $26.99 per share.

Other Recently Issued and Effective Authoritative Accounting Guidance

ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” ASU 2020-04 provides optional expedients and exceptions for accounting related to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. ASU 2020-04 applies only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform and do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. ASU 2020-04 was effective upon issuance, and based upon the amendments provided in ASU 2022-06 discussed below, can generally be applied through December 31, 2024. The adoption of ASU 2020-04 did not have a significant impact on our financial statements.

ASU 2021-01, “Reference Rate Reform (Topic 848): Scope.” ASU 2021-01 clarifies that certain optional expedients and exceptions in ASC 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. ASU 2021-01 also amends the expedients and exceptions in ASC 848 to capture the incremental consequences of the scope clarification and to tailor the existing guidance to derivative instruments affected by the discounting transition. ASU 2021-01 was effective upon issuance, and based upon the amendments provided in ASU 2022-06 discussed below, can generally be applied through December 31, 2024. The adoption of ASU 2021-01 did not have a significant impact on our financial statements.

ASU 2022-02, "Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures." ASU 2022-02 eliminates the accounting guidance for troubled debt restructurings in ASC Subtopic 310-40, Receivables - Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. ASU 2022-02 will also require that an entity disclose current-period gross charge-offs by year of origination for financial receivables and net investment leases within the scope of ASC Subtopic 326-20, Financial Instruments - Credit Losses - Measured at Amortized Cost. ASU 2022-02 became effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, though early adoption is permitted. The adoption of ASU 2022-02 did not have a significant impact on our financial statements.

ASU 2022-06, "Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848." ASU 2022-06 extends the period of time preparers can utilize the reference rate reform relief guidance provided by ASU 2020-04 and ASU 2021-01, which are discussed above. ASU 2022-06, which was effective upon issuance, defers the sunset date of this prior guidance from December 31, 2022 to December 31, 2024, after which entities will no longer be permitted to apply the relief guidance in Topic 848. The adoption of ASU 2022-06 did not have a significant impact on our financial statements.

Investment Securities

Management classifies debt securities as held-to-maturity, available-for-sale, or trading based on its intent. Securities that management has the positive intent and ability to hold to maturity are classified as held-to-maturity and recorded at amortized cost, adjusted for amortization of premiums and accretion of discounts, which are recognized as adjustments to interest income using the interest method. Securities not classified as held-to-maturity or trading are classified as available-for-sale and recorded at fair value, with unrealized holding gains and losses (those for which no allowance for credit losses are recorded) reported as a component of other comprehensive income, net of tax. Management determines the appropriate classification of securities at the time of purchase.

Interest income includes amortization of purchase premiums and discounts over the period to maturity using a level-yield method, except for premiums on callable securities, which are amortized to their earliest call date. Realized gains and losses are recorded on the sale of securities in noninterest income.

The Company has made a policy election to exclude accrued interest from the amortized cost basis of securities and report accrued interest separately in other assets on the consolidated balance sheets. A security is placed on nonaccrual status at the time any principal or interest payments become more than 90 days delinquent or if full collection of interest or principal becomes uncertain. Accrued interest for a security placed on nonaccrual is reversed against interest income. There was no accrued interest related to securities reversed against interest income for the three and nine-months ended September 30, 2023 and 2022.

The Company records its available-for-sale securities portfolio at fair value. Fair values of these securities are determined based on methodologies in accordance with current authoritative accounting guidance. Fair values are volatile and may be influenced by a number of factors, including market interest rates, prepayment speeds, discount rates, credit ratings, and yield curves. Fair values for securities are based on quoted market prices, where available. If quoted market prices are not available, fair values are based on the quoted prices of similar instruments or an estimate of fair value by using a range of fair value estimates in the marketplace as a result of the illiquid market, specific to the type of security.

The Company’s investment portfolio currently consists of obligations of state and political subdivisions, mortgage pass-through securities, corporate bonds and general obligation or revenue based municipal bonds. Pricing for such securities is generally readily available and transparent in the market. The Company utilizes independent third-party pricing services to value its investment securities, which the Company reviews as well as the underlying pricing methodologies for reasonableness and to ensure such prices are aligned with pricing matrices. The Company validates prices supplied by the independent pricing services by comparison to prices obtained from other third-party sources on a quarterly basis.

Allowance for Credit Losses – Available-for-Sale Securities

For available-for-sale securities in an unrealized loss position, we first assess whether we intend to sell, or it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, any previously recognized allowances are charged-off and the security’s amortized cost basis is written down to fair value through income as a provision for credit losses. For available-for-sale securities that do not meet the aforementioned criteria, we evaluate whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis.

Management has made the accounting policy election to exclude accrued interest receivable on available-for-sale securities from the estimate of credit losses. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit losses. Available-for-sale securities are charged-off against the allowance or, in the absence of any allowance, written down through income when deemed uncollectible by management or when either of the aforementioned criteria regarding intent or requirement to sell is met.

At September 30, 2023 and 2022, and December 31, 2022, no allowance for credit losses - available-for-sale securities was recorded.

Allowance for Credit Losses – Held-to-Maturity Securities

The allowance for credit losses on held-to-maturity securities is a contra-asset valuation account, calculated in accordance with ASC 326, that is deducted from the amortized cost basis of held-to-maturity securities to present management’s best estimate of the net amount expected to be collected. Held-to-maturity securities are charged-off against the allowance when deemed uncollectible by management. Adjustments to the allowance are reported in our income statement as a component of credit loss expense. Management measures expected credit losses on held-to-maturity securities on a collective basis by major security type with each type sharing similar risk characteristics and considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. Management has made the accounting policy election to exclude accrued interest receivable on held-to-maturity securities from the estimate of credit losses.

At September 30, 2023 and 2022, and December 31, 2022, the Company held no securities that were classified as held-to-maturity.

Loans Held-for-Investment

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost, net of the allowance for credit losses. Amortized cost is the principal balance outstanding, net of purchase premiums and discounts, fair value hedge accounting adjustments, deferred loan fees and costs. The Company has made a policy election to exclude accrued interest from the amortized cost basis of loans and report accrued interest separately from the related loan balance in other assets on the condensed consolidated balance sheets.

Interest on loans is calculated by using the simple interest method on daily balances of the principal amounts outstanding. The Company defers and amortizes net loan origination fees and costs as an adjustment to yield.

Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Loans are placed on nonaccrual status when, in management’s opinion, the borrower may be unable to meet payment obligations as they become due, as well as when required by regulatory provisions. In determining whether or not a borrower may be unable to meet payment obligations for each class of loans, we consider the borrower’s debt service capacity through the analysis of current financial information, if available, and/or current information with regards to our collateral position. Regulatory provisions would typically require the placement of a loan on nonaccrual status if principal or interest has been in default for a period of 90 days or more unless the loan is both well secured and in the process of collection or full payment of principal and interest is not expected. Loans may be placed on nonaccrual status regardless of whether or not such loans are considered past due. When interest accrual is discontinued, all unpaid accrued interest is reversed. Interest income on nonaccrual loans is recognized only to the extent that cash payments are received in excess of principal due. A loan may be returned to accrual status when all the principal and interest amounts contractually due are brought current and future principal and interest amounts contractually due are reasonably assured.

Further information regarding our accounting policies related to past due loans, nonaccrual loans and loans to borrowers experiencing financial difficulty is presented in Note 3.

Acquired Loans

Loans acquired in connection with acquisitions are recorded at their acquisition-date fair value. The allowance for credit losses related to the acquired loan portfolio is not carried over. Upon the adoption of ASC 326, acquired loans are classified into two categories based on the credit risk characteristics of the underlying borrowers as either purchased credit deteriorated (“PCD”) loans, or loans with no evidence of credit deterioration (“non-PCD”).

PCD loans are defined as a loan or pool of loans that have experienced more-than-insignificant credit deterioration since the origination date. The Company uses a combination of individual and pooled review approaches to determine if acquired loans are PCD. At acquisition, the Company considers a number of factors to determine if an acquired loan or pool of loans has experienced more-than-insignificant credit deterioration.

The initial allowance related to PCD loans that share similar risk characteristics is established using a pooled approach. The Company uses either a discounted cash flow or weighted average remaining life method to determine the required level of the allowance. PCD loans that were classified as nonaccrual as of the acquisition date and are collateral dependent are assessed for allowance on an individual basis. For PCD loans, an initial allowance is established on the acquisition date. Subsequent to the acquisition date, the initial allowance for credit losses on PCD loans will increase or decrease based on future evaluations, with changes recognized in the provision for credit losses.

Non-PCD loans are pooled into segments together with originated loans that share similar risk characteristics and have an allowance established on the acquisition date, which is recognized in the current period provision for credit losses as well as a fair value adjustment to the amortized cost of the loan and accreted into income over the life of the loan.

Determining the fair value of the acquired loans involves estimating the principal and interest payment cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. Management considers a number of factors in evaluating the acquisition-date fair value including the remaining life, interest rate profile, market interest rate environment, payment schedules, risk ratings, probability of default and loss given default, and estimated prepayment rates. For PCD loans, the non-credit discount or premium is allocated to individual loans as determined by the difference between the loan’s unpaid principal balance and amortized cost basis. For non-PCD loans, the fair value discount or premium is allocated to individual loans and recognized into interest income on a level yield basis over the remaining expected life of the loan.

Allowance for Credit Losses - Loans

The allowance for credit losses (“allowance” or “ACL”) is a contra-asset valuation account, calculated in accordance with ASC 326, that is deducted from the amortized cost basis of loans. The ACL represents an amount which, in management’s judgement, is adequate to absorb the lifetime expected credit losses that may be experienced on outstanding loans at the balance sheet date based on the evaluation of the size and current risk characteristics of the loan portfolio, past events, current conditions, reasonable and supportable forecasts of future economic conditions and prepayment experience. The allowance for credit losses is measured and recorded upon the initial recognition of a financial asset. Determination of the adequacy of the allowance is inherently complex and requires the use of significant and highly subjective estimates. Loans are charged-off against the allowance when deemed uncollectible by management. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Adjustments to the allowance are reported in our income statement as a component of the provision for credit losses. Management has made the accounting policy election to exclude accrued interest receivable on loans from the estimate of credit losses.

The Company’s methodology for estimating the allowance includes: (1) a collective quantified reserve that reflects the Company’s historical default and loss experience adjusted for expected economic conditions throughout a reasonable and supportable period and the Company’s prepayment and curtailment rates; (2) collective qualitative factors that consider concentrations of the loan portfolio, expected changes to the economic forecasts, large relationships, early delinquencies, and factors related to credit administrations, including, among others, loan-to-value ratios, borrowers’ risk rating and credit score migrations; and (3) individual allowances on loans where borrowers are experiencing financial difficulty or when the Company determines that the foreclosure is probable.

In calculating the allowance for credit losses, most loans are segmented into pools based upon similar characteristics and risk profiles. Common characteristics and risk profiles include the type/purpose of loan, underlying collateral, geographical similarity and historical/expected credit loss patterns. In developing these loan pools for the purposes of modeling expected credit losses, we also analyzed the degree of correlation in how loans within each portfolio respond when subjected to varying economic conditions and scenarios as well as other portfolio stress factors. For modeling purposes, our loan portfolio segments include Commercial and Industrial (“C&I”), Municipal, Agricultural, Construction and Development, Farm, Non-Owner Occupied and Owner Occupied Commercial Real Estate (“CRE”), Residential, Consumer Auto, and Consumer Non-Auto. We periodically reassess each pool to ensure the loans within the pool continue to share similar characteristics and risk profiles and to determine whether further segmentation is necessary. Refer to Note 3 for more details on the Company’s portfolio segments.

The Company applies two methodologies to estimate the allowance on its pooled portfolio segments; discounted cash flows method and weighted average remaining life method. Allowance estimates on the following portfolio segments are calculated using the discounted cash flows method: C&I, Municipal, Construction and Development, Farm, Non-Owner Occupied and Owner Occupied CRE, and Residential. Allowance estimates on the following portfolio segments are calculated using the remaining life method: Agriculture, Consumer Auto and Consumer Non-Auto. The models related to these methodologies utilize the Company’s historical default and loss experience adjusted for future economic forecasts. The reasonable and supportable forecast period represents a one-year economic outlook for the applicable economic variables. Following the end of the reasonable and supportable forecast period, expected losses revert back to the historical mean over the next two years on a straight-line basis. Economic variables that have the most significant impact on the allowance include: Texas unemployment rate, Texas house price index, and Texas retail sales index. Contractual loan level cash flows within the discounted cash flows methodology are adjusted for the Company’s historical prepayment and curtailment rate experience.

In some cases, management may determine that an individual loan exhibits unique risk characteristics which differentiate the loan from other loans within our loan pools. In such cases, the loans are evaluated for expected credit losses on an individual basis and excluded from the collective evaluation. Specific allocations of the allowance for credit losses are determined by analyzing the borrower’s ability to repay amounts owed, collateral deficiencies, the relative risk rating of the loan and economic conditions affecting the borrower’s industry, among other things. A loan is considered to be collateral dependent when, based upon management’s assessment, the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the sale of the collateral. In such cases, expected credit losses are based on the fair value of the collateral at the measurement date, adjusted for estimated selling costs if satisfaction of the loan depends on the sale of the collateral. We reevaluate the fair value of collateral supporting collateral dependent loans on an ongoing basis.

Management qualitatively adjusts model results for risk factors that are not considered within our modeling processes but are nonetheless relevant in assessing the expected credit losses within our loan pools. These qualitative factor (“Q-Factor”) adjustments may increase or decrease management’s estimate of expected credit losses by a calculated percentage or amount based upon the estimated level of risk. The various risks that may be considered in making Q-Factor adjustments include, among other things, the impact of (i) changes in lending policies and procedures, including changes in underwriting standards and practices for collections, write-offs, and recoveries, (ii) actual and expected changes in national, regional, and local economic and business conditions and developments that affect the collectability of the loan pools, (iii) changes in the nature, volume and size of a loan or the loan pools and in the terms of the underlying loans, (iv) changes in the experience, ability, and depth of our lending management and staff, (v) changes in volume and severity of past due financial assets, the volume of nonaccrual assets, and the volume and severity of adversely classified or graded assets, (vi) changes in the quality of our credit review function, (vii) changes in the value of the underlying collateral for loans that are non-collateral dependent, (viii) the existence, growth, and effect of any concentrations of credit and (ix) other factors such as the regulatory, legal and technological environments, competition, and events such as natural disasters or health pandemics.

Management believes it uses relevant information available to make determinations about the allowance and that it has established the existing allowance in accordance with GAAP. However, the determination of the allowance requires significant judgment, and estimates of expected lifetime losses in the loan portfolio can vary significantly from the amounts actually observed. While management uses available information to recognize expected losses, future additions to the allowance may be necessary based on changes in the loans comprising the portfolio, changes in the current and forecasted economic conditions, changes to the interest rate environment which may directly impact prepayment and curtailment rate assumptions, and changes in the financial condition of borrowers.

Allowance for Credit Losses - Off-Balance-Sheet/Reserve for Unfunded Commitments

The allowance for credit losses on off-balance-sheet credit exposures is a liability account, calculated in accordance with ASC 326, representing expected credit losses over the contractual period for which we are exposed to credit risk resulting from a contractual obligation to extend credit. These obligations include unfunded lines of credit, commitments to extend credit and federal funds sold to correspondent banks and standby letters of credit. No allowance is recognized if we have the unconditional right to cancel the obligation. The allowance is reported as a component of accrued interest payable and other liabilities in our consolidated balance sheets. Adjustments to the allowance are reported in our income statement as a component of the provision for credit losses. At September 30, 2023 and 2022, and December 31, 2022, the Company’s reserve for unfunded commitments totaled $7,903,000, $10,879,000 and $12,323,000, respectively, which is included in other liabilities in the consolidated balance sheet.

Other Real Estate

Other real estate owned is foreclosed property held pending disposition and is initially recorded at fair value, less estimated costs to sell, and is included in other assets in the consolidated balance sheet. At foreclosure, if the fair value of the real estate, less estimated costs to sell, is less than the Company’s recorded investment in the related loan, a write-down is recognized through a charge to the allowance for credit losses. Any subsequent reduction in value is recognized by a charge to income. Operating and holding expenses of such properties, net of related income, and gains/losses on their disposition are included in net gain (loss) on sale of foreclosed assets as incurred.

Bank Premises and Equipment

Bank premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed principally on a straight-line basis over the estimated useful lives of the related assets. Leasehold improvements are amortized over the life of the respective lease or the estimated useful lives of the improvements, whichever is shorter.

Business Combinations, Goodwill and Other Intangible Assets

The Company accounts for all business combinations under the purchase method of accounting. Tangible and intangible assets and liabilities of the acquired entity are recorded at fair value. Intangible assets with finite useful lives represent the future benefit associated with the acquisition of the core deposits and are amortized over seven years, utilizing a method that approximates the expected attrition of the deposits. Goodwill with an indefinite life is not amortized, but rather tested annually for impairment as of June 30 each year. There was no impairment recorded during the nine-months ended September 30, 2023 or 2022, respectively.

Securities Sold Under Agreements to Repurchase

Securities sold under agreements to repurchase, which are classified as borrowings, generally mature within one to four days from the transaction date. Securities sold under agreements to repurchase are reflected at the amount of the cash received in connection with the transaction. The Company may be required to provide additional collateral based on the estimated fair value of the underlying securities.

Segment Reporting

The Company has determined that its banking regions meet the aggregation criteria of the current authoritative accounting guidance since each of its banking regions offer similar products and services, operate in a similar manner, have similar customers and report to the same regulatory authority, and therefore operate one line of business (community banking) located in a single geographic area (Texas).

Statements of Cash Flows

For purposes of reporting cash flows, cash and cash equivalents includes cash on hand, amounts due from banks, including interest-bearing deposits in banks with original maturity of 90 days or less, and federal funds sold.

Accumulated Other Comprehensive Earnings (Loss)

Unrealized net losses on the Company’s available-for-sale securities, net of applicable income taxes, totaled $639,934,000, $632,421,000 and $535,228,000 at September 30, 2023, and 2022, and December 31, 2022, respectively, are included in accumulated other comprehensive earnings (loss) as a separate component of shareholders' equity.

Income Taxes

The Company’s provision for income taxes is based on income before income taxes adjusted for permanent differences between financial reporting and taxable income. Deferred tax assets and liabilities are determined using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. As of September 30, 2023, and 2022, and December 31, 2022, deferred tax assets totaled $173,032,000, $168,398,000 and $145,511,000, respectively, and were included in other assets on the consolidated balance sheets.

Stock Based Compensation

The Company grants stock options for a fixed number of shares to employees with an exercise price equal to the fair value using the Black-Scholes model of the shares at the grant date. The grant date fair value is amortized over the vesting period which generally is three, five or six years. The Company also grants restricted stock and/or units for a fixed number of shares which generally vests over periods of one to three years, and performance stock units which vest over a 3-year period based on Company performance metrics relative to a defined peer group. For stock option grants, the exercise price is established based on the closing trading price. No adjustments have been necessary to properly value the grant based on the terms or other conditions of the grants. Expense is recognized based on the fair value of the portion of stock-based payment awards that ultimately expected to vest, reduced for forfeitures based on grant-date fair value. See Note 8 for further information.

Advertising Costs

Advertising costs are expensed as incurred.

Per Share Data

Net earnings per share (“EPS”) are computed by dividing net earnings by the weighted average number of common shares outstanding during the period. The Company calculates dilutive EPS assuming all outstanding stock options to purchase common shares and unvested restricted stock shares and units have been exercised and/or vested at the beginning of the year (or the time of issuance, if later.) The dilutive effect of the outstanding options and restricted stock is reflected by application of the treasury stock method, whereby the proceeds from the exercised options and unearned compensation for both restricted stock and stock options are assumed to be used to purchase common shares at the average market price during the respective period. There were 864,000 and 478,000 anti-dilutive shares for the three and nine-months ended September 30, 2023, respectively, that were excluded from the computation of EPS. There were 346,000 and 272,000 anti-dilutive shares for the three and nine-months ended September 30, 2022, respectively, that were excluded from the computation of EPS. The following table reconciles the computation of basic EPS to diluted EPS:

The Company did not hold any securities classified as held-to-maturity at September 30, 2023, September 30, 2022, or December 31, 2022.

The Company invests in mortgage-backed securities that have expected maturities that differ from their contractual maturities. These differences arise because borrowers may have the right to call or prepay obligations with or without a prepayment penalty. These securities include collateralized mortgage obligations (CMOs) and other asset backed securities. The expected maturities of these securities at September 30, 2023 and 2022, and December 31, 2022, were computed by using scheduled amortization of balances and historical prepayment rates.

The amortized cost and estimated fair value of available-for-sale securities at September 30, 2023, by contractual and expected maturity, are shown below (dollars in thousands):

	Amortized		Estimated
	Cost Basis		Fair Value
Due within one year	$	335,508	$	327,912

The number of investments in an unrealized loss position totaled 892 at September 30, 2023. We believe any unrealized losses in the U.S. treasury securities, obligations of state and political subdivisions, residential and commercial mortgage-backed and asset-backed investment securities, and corporate bonds and other at September 30, 2023 and 2022, and December 31, 2022, are due to changes in interest rates and not credit-related events. As such, no allowance for credit losses is required on these securities at September 30, 2023 and 2022, and December 31, 2022. Unrealized losses on investment securities are expected to recover over time as these securities approach maturity.

From a credit risk standpoint, the Company rates its loans in one of five categories: (i) pass, (ii) special mention, (iii) substandard, (iv) doubtful or (v) loss (which are charged-off).

The ratings of loans reflect a judgment about the risks of default and loss associated with the loan. The Company reviews the ratings on our credits as part of our ongoing monitoring of the credit quality of our loan portfolio. Ratings are adjusted to reflect the degree of risk and loss that are felt to be inherent in each credit as of each reporting period. Our methodology is structured so that specific allocations are increased in accordance with deterioration in credit quality (and a corresponding increase in risk and loss) or decreased in accordance with improvement in credit quality (and a corresponding decrease in risk and loss).

Credits rated special mention show clear signs of financial weaknesses or deterioration in credit worthiness, however, such concerns are not so pronounced that the Company generally expects to experience significant loss within the short-term. Such credits typically maintain the ability to perform within standard credit terms and credit exposure is not as prominent as credits rated more harshly.

Credits rated substandard are those in which the normal repayment of principal and interest may be, or has been, jeopardized by reason of adverse trends or developments of a financial, managerial, economic or political nature, or important weaknesses exist in collateral. A protracted workout on these credits is a distinct possibility. Prompt corrective action is therefore required to strengthen the Company’s position, and/or to reduce exposure and to assure that adequate remedial measures are taken by the borrower. Credit exposure becomes more likely in such credits and a serious evaluation of the secondary support to the credit is performed.

Credits rated doubtful are those in which full collection of principal appears highly questionable, and which some degree of loss is anticipated, even though the ultimate amount of loss may not yet be certain and/or other factors exist which could affect collection of debt. Based upon available information, positive action by the Company is required to avert or minimize loss. Credits rated doubtful are generally also placed on nonaccrual.

Modifications of receivables to debtors experiencing financial difficulty

On January 1, 2023, the Company adopted the accounting guidance in ASU 2022-02, which eliminates the recognition and measurement of a TDR. Due to the removal of the TDR designation, the Company evaluates all loan restructurings according to the accounting guidance for loan modifications to determine if the restructuring results in a new loan or a continuation of the existing loan. Loan modifications to borrowers experiencing financial difficulty that result in a direct change in the timing or amount of contractual cash flows include situations where there is principal forgiveness, term extensions, interest rate reduction, and combinations of the listed modifications. Therefore, the disclosures related to loan restructurings are only for modifications that directly affect cash flows.

An assessment of whether a borrower is experiencing financial difficulty is made on the date of a modification. Because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses due to the measurement methodologies used to estimate the allowance, a change to the allowance for credit losses is generally not recorded upon modification. During the nine-months ended September 30, 2023, loan modifications made to borrowers experiencing financial difficulty was insignificant.

Loans Held for Sale

Note 4 - Loans Held-for-Sale

Loans held-for-sale totaled $12,229,000, $18,815,000 and $11,965,000 at September 30, 2023 and 2022, and December 31, 2022, respectively. At September 30, 2023 and 2022, and December 31, 2022, $321,000, $2,923,000 and $1,468,000, respectively, are valued at the lower of cost or fair value, and the remaining amounts are valued under the fair value option.

These loans, which are sold on a servicing released basis, are valued using a market approach by utilizing either: (i) the fair value of the securities backed by similar mortgage loans, adjusted for certain factors to approximate the fair value of a whole mortgage loan, including the value attributable to mortgage servicing and credit risk, (ii) current commitments to purchase loans or (iii) recent observable market trades for similar loans, adjusted for credit risk and other individual loan characteristics. As these prices are derived from market observable inputs, the Company classifies these valuations as Level 2 in the fair value disclosures (see Note 9). Interest income on mortgage loans held-for-sale is recognized based on the contractual rates and reflected in interest income on loans in the consolidated statements of earnings. The Company has no continuing ownership in any residential mortgage loans sold.

The Company originates certain mortgage loans for sale in the secondary market. The mortgage loan sales contracts contain indemnification clauses should the loans default, generally in the first three to six months, or if documentation is determined not to be in compliance with regulations. The Company’s historic losses as a result of these indemnities have been insignificant.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Note 5 - Derivative Financial Instruments

The Company enters into interest rate lock commitments (“IRLCs”) with customers to originate residential mortgage loans at a specific interest rate that are ultimately sold in the secondary market. These commitments, which contain fixed expiration dates, offer the borrower an interest rate guarantee provided the loan meets underwriting guidelines and closes within the timeframe established by the Company.

The Company purchases forward mortgage-backed securities contracts to manage the changes in fair value associated with changes in interest rates related to a portion of the IRLCs. These instruments are typically entered into at the time the IRLC is made in the aggregate.

The fair values of IRLCs are based on current secondary market prices for underlying loans and estimated servicing value with similar coupons, maturity and credit quality, subject to the anticipated loan funding probability (pull-through rate) net of estimated costs to originate the loan. The fair value of IRLCs is subject to change primarily due to changes in interest rates and the estimated pull-through rate. These commitments are classified as Level 2 in the fair value disclosures (see Note 9), as the valuations are based on observable market inputs.

Forward mortgage-backed securities contracts are exchange-traded or traded within highly active dealer markets. In order to determine the fair value of these instruments, the Company utilizes the exchange price or dealer market price for the particular derivative contract and these instruments are therefore classified as Level 2 in the fair value disclosures (see Note 9). The estimated fair values are subject to change primarily due to changes in interest rates. The impact of these forward contracts is included in gain on sale and fees on mortgage loans in the statement of earnings.

These financial instruments are not designated as hedging instruments for accounting purposes. All derivatives are carried at fair value in either other assets or other liabilities and are reflected in the gain on sale and fees on mortgage loans in the consolidated statement of earnings.

The following tables provide the outstanding notional balances and fair values of outstanding derivative positions (dollars in thousands):

September 30, 2023:	Outstanding Notional Balance		Asset Derivative Fair Value		Liability Derivative Fair Value

Borrowings

Note 6 – Borrowings

Borrowings consisted of the following (dollars in thousands):

	September 30,				December 31,
	2023		2022		2022
Securities sold under agreements with customers to repurchase	$	621,791	$	749,278	$	618,829
Short-term borrowings		108,700		4,250		2,625
Other borrowings		21,053		21,053		21,053
Total	$	751,544	$	774,581	$	642,507

Securities sold under repurchase agreements are generally with significant customers of the Company that require short-term liquidity for their funds for which the Company pledges certain securities that have a fair value equal to at least the amount of the borrowings. The agreements mature daily and therefore the risk arising from a decline in the fair value of the collateral pledged is minimal. The securities pledged are mortgage-backed securities. These agreements do not include “right of set-off” provisions and therefore the Company does not offset such agreements for financial reporting purposes.

The Company renewed its loan agreement, effective June 30, 2023, with Frost Bank. Under the loan agreement, as renewed and amended, we are permitted to draw up to $25,000,000 on a revolving line of credit. There was no outstanding balance under the line of credit as of September 30, 2023.

During 2021, the Company began investing in qualifying Community Development Entities ("CDE") under the federal New Market Tax Credits ("NMTC") program. See Note 7 for further discussion of our activity and related balances on the consolidated balance sheets, including the $21,053,000 in other borrowings shown above.

Income Taxes

Note 7 - Income Taxes

Income tax expense was $10,848,000 for the third quarter of 2023 as compared to $12,095,000 for the same period in 2022. The Company’s effective tax rates on pretax income were 17.96% and 16.93% for the third quarters of 2023 and 2022, respectively. Income tax expense was $34,291,000 for the nine-months ended September 30, 2023 as compared to $34,359,000 for the same period in 2022. The Company's effective tax rates on pretax income were 18.31% and 16.35% for the nine-months ended September 30, 2023 and 2022, respectively. The effective tax rates differ from the statutory federal tax rate of 21% primarily due to tax exempt interest income earned on certain investment securities and loans, the deductibility of dividends paid to our employee stock ownership plan, excess tax benefits for distributions under our deferred compensation plan and vesting of equity awards, and NMTC benefits.

Low Income Housing Tax Credit Investments - During 2021, the Company began investing in an affordable housing fund that will invest in real estate projects that qualify for the federal low-income housing tax credit ("LIHTC") program designed to promote private development of low income housing. The investments made by the fund will generate a return to the Company primarily through the realization of LIHTCs, and also through federal tax deductions generated from the ongoing operating losses from the investees of the fund. The Company's investment in the fund will be amortized through income tax expense using the proportional amortization method as related tax credits are utilized by the Company. The initial capital contribution commitment to the fund was for up to $5,500,000. Contributions were $539,000 at September 30, 2023, and $131,000 at September 30, 2022, and December 31, 2022, respectively, which is included in other assets on the consolidated balance sheet.

New Market Tax Credit Investments - During 2021, the Company began investing in qualifying CDEs under the federal NMTC program. NMTC investments are made through the third-party CDEs which are qualified through the U.S. Department of Treasury and receive periodic allocation of amounts under the NMTC program. NMTCs are generated from qualified investments by the CDEs utilizing equity investments made by a taxpayer, like the Company. Through these equity investments, the Company will receive the tax benefits from the NMTCs equal to 39% of the qualified investment from the CDE yield method and related tax credits are allocated to the Company. At September 30, 2023, September 30, 2022, and December 31, 2022, the consolidated balance sheet of the Company included a $18,000,000 loan to the investee in loans and the $21,053,000 leveraged loan from the investee in other borrowings (see Note 6). At September 30, 2023 and 2022, and December 31, 2022, the consolidated balance sheet of the Company included CDE investments in other assets of $26,009,000, $29,000,000, and $26,825,000, respectively.

Note 8 - Stock Based Compensation

On April 27, 2021, the Company’s shareholders approved the 2021 Omnibus Stock and Incentive Plan (“2021 Plan”) and reserved 2,500,000 shares of the Company’s common stock for issuance under this plan. At September 30, 2023, the Company had 1,562,362 shares of stock remaining for issuance under the plan. The 2021 Plan superseded all prior stock option and restricted stock plans with shares previously reserved for issuance under such plans cancelled.

Restricted Stock Units

Under the 2021 Plan, the Company grants restricted stock units under compensation arrangements for the benefit of employees, senior and executive officers and directors. Restricted stock unit grants are subject to time-based vesting. The total number of restricted stock units granted represents the maximum number of restricted stock units eligible to vest based upon the service conditions set forth in the grant agreements. The following table summarizes information about the changes in restricted stock units for the nine-months ended September 30, 2023 and 2022.

Performance Stock Units

Also under the 2021 Plan, the Company awards performance-based restricted stock units (“PSUs”) to employees, senior and executive officers, and directors. Under the terms of the award, the number of units that will vest and convert to shares of common stock will be based on the extent to which the Company achieves specific performance criteria during the fixed three-year performance period. The number of shares issued upon vesting will range from 0% to 200% of the PSUs granted. The PSUs vest at the end of a three-year period based 50% each on average adjusted earnings per share growth and return on average assets as reported, adjusted for unusual gains/losses, merger expenses, and other items as approved by the compensation committee of the Company's board of directors. Performance for each period is measured relative to other U.S. publicly traded banks with $10 billion to $50 billion in assets. Compensation expense for the PSUs will be estimated each period based on the fair value of the stock at the grant date and the most probable outcome of the performance condition, adjusted for the passage of time within the vesting period of the awards.

The following table summarizes information about the changes in PSUs as of and for the nine-months ended September 30, 2023 and 2022.

As of September 30, 2023 and 2022, there were $3,998,000 and $4,105,000 respectively, of total unrecognized compensation cost related to unvested restricted stock, restricted stock units and performance-based restricted stock units which is expected to be recognized over a weighted-average period of 1.27 years and 1.23 years, respectively. At September 30, 2023 and 2022, and December 31, 2022, there was $107,000, $72,000 and $74,000, respectively, accrued in other liabilities related to dividends declared to be paid upon vesting.

Stock Option Plans

Prior to the approval of the 2021 Plan, the 2012 Incentive Stock Option Plan (the “2012 Plan”) provided for the granting of options to employees of the Company at prices not less than market value at the date of the grant. The 2012 Plan provided that options granted vest and are exercisable after two years from the date of grant and vest at a rate of 20% each year thereafter and have a 10-year term. The most recent grants from the 2021 Plan provided that 20% of the options granted vest and are exercisable after one year from the date of grant and the remaining options vest and are exercisable at a rate of 20% each year thereafter and have a 10-year term. Shares are issued under the 2012 Plan and the 2021 Plan from available authorized shares. An analysis of stock option activity for the nine-months ended September 30, 2023 is presented in the table and narrative below:​​​​​​​

	Shares			Weighted- Average Ex. Price
Outstanding, December 31, 2022		1,490,413		$	29.99
Granted		253,228			29.53
Exercised		(84,000	)		18.36
Cancelled		(50,535	)		42.90
Outstanding, September 30, 2023		1,609,106			30.12
Exercisable, September 30, 2023		938,924		$	24.96

The options outstanding at September 30, 2023 had exercise prices ranging between $15.43 and $48.91. Stock options have been adjusted retroactively for the effects of stock dividends and splits.

The Company grants incentive stock options for a fixed number of shares with an exercise price equal to the fair value of the shares at the date of grant to employees.

The Company recorded stock option expense totaling $391,000 and $360,000 for the three-months ended September 30, 2023 and 2022, respectively. The Company recorded stock option expense totaling $1,280,000 and $992,000 for the nine-months ended September 30, 2023 and 2022, respectively.

As of September 30, 2023, there was $5,746,000 of total unrecognized compensation cost related to unvested share-based compensation arrangements granted under the plans. That cost is expected to be recognized over a weighted-average period of 1.67 years. The total fair value of shares vested during the nine-months ended September 30, 2023 and 2022 was $2,110,000 and $1,747,000, respectively.

Fair Value Disclosures [Abstract]

Fair Value Disclosures

Note 9 - Fair Value Disclosures

The authoritative accounting guidance for fair value measurements defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability shall not be adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact, and (iv) willing to transact.

The authoritative accounting guidance requires the use of valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present amount on a discounted basis. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement costs). Valuation techniques should be consistently applied. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. In that regard, the authoritative guidance establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

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

•Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (for example, interest rates, volatilities, prepayment speeds, loss severities, credit risks and default rates) or inputs that are derived principally from or corroborated by observable market data by correlation or other means.

•Level 3 Inputs – Significant unobservable inputs that reflect an entity’s own assumptions that market participants would use in pricing the assets or liabilities.

A description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below.

In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date.

Securities classified as available-for-sale and trading are reported at fair value utilizing Level 1 and Level 2 inputs. For these securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include market spreads, cash flows, the United States Treasury yield curve, live trading levels, trade execution data, dealer quotes, market consensus prepayment speeds, credit information and the security’s terms and conditions, among other items.

See Notes 4 and 5 related to the determination of fair value for loans held-for-sale, IRLCs and forward mortgage-backed securities trades.

There were no transfers between Level 2 and Level 3 during the three and nine-months ended September 30, 2023 and 2022, and the year ended December 31, 2022.

The following table summarizes the Company’s available-for-sale securities, loans held-for-sale, and derivatives which are measured at fair value on a recurring basis, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (dollars in thousands):

The following table summarizes the Company’s gains on sale and fees of mortgage loans for the three and nine-months ended September 30, 2023 and 2022 (dollars in thousand):

	Three-Months Ended September 30,						Nine-Months Ended September 30,

* This includes gains on loans held-for-sale carried under the fair value method and lower of cost or market.

No residential mortgage loans held-for-sale were 90 days or more past due or considered nonaccrual as of September 30, 2023, September 30, 2022, or December 31, 2022. No significant credit losses were recognized on mortgage loans held-for-sale for the three and nine-months ended September 30, 2023 and 2022.

Certain non-financial assets and non-financial liabilities measured at fair value on a nonrecurring basis include other real estate owned, goodwill and other intangible assets, and other non-financial long-lived assets. Non-financial assets measured at fair value on a non-recurring basis during the nine-months ended September 30, 2023 include other real estate owned which, subsequent to their initial transfer to other real estate owned from loans, were re-measured at fair value through a write-down included in gain (loss) on sale of foreclosed assets. During the reported periods, all fair value measurements for foreclosed assets utilized Level 2 inputs based on observable market data, generally third-party appraisals, or Level 3 inputs based on customized discounting criteria. These appraisals are evaluated individually and discounted as necessary due to the age of the appraisal, lack of comparable sales, expected holding periods of property or special use type of the property. Such discounts vary by appraisal based on the above factors but generally range from 5% to 25% of the appraised value. Re-evaluation of other real estate owned is performed at least annually as required by regulatory guidelines or more often if particular circumstances arise. There were no other real estate owned properties that were re-measured subsequent to their initial transfer to other real estate owned during the three and nine-months ended September 30, 2023 and 2022.

At September 30, 2023, other real estate owned totaled $15,000. At September 30, 2022 and December 31, 2022, the Company had no other real estate owned.

The Company is required under current authoritative accounting guidance to disclose the estimated fair value of their financial instrument assets and liabilities including those subject to the requirements discussed above. For the Company, as for most financial institutions, substantially all of its assets and liabilities are considered financial instruments. Many of the Company’s financial instruments, however, lack an available trading market as characterized by a willing buyer and willing seller engaging in an exchange transaction.

The estimated fair value amounts of financial instruments have been determined by the Company using available market information and appropriate valuation methodologies. However, considerable judgment is required to interpret data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize in a current market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.

In addition, reasonable comparability between financial institutions may not be likely due to the wide range of permitted valuation techniques and numerous estimates that must be made given the absence of active secondary markets for many of the financial instruments. This lack of uniform valuation methodologies also introduces a greater degree of subjectivity to these estimated fair values.

Cash and due from banks, federal funds sold, interest-bearing deposits in banks and accrued interest receivable and payable are liquid in nature and considered Levels 1 or 2 of the fair value hierarchy.

Financial instruments with stated maturities have been valued using a present value discounted cash flow with a discount rate approximating current market for similar assets and liabilities and are considered Levels 2 and 3 of the fair value hierarchy. Financial instrument liabilities with no stated maturities have an estimated fair value equal to both the amount payable on demand and the carrying value and are considered Level 1 of the fair value hierarchy.

The carrying value and the estimated fair value of the Company’s contractual off-balance-sheet unfunded lines of credit, loan commitments and letters of credit, which are generally priced at market at the time of funding, are not material.

The estimated fair values and carrying values of all financial instruments under current authoritative guidance were as follows (dollars in thousands).

	September 30,										December 31,
	2023				2022						2022

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The Company’s significant estimates include its allowance for credit losses and its valuation of financial instruments.

Consolidation

Consolidation

The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly-owned. All significant intercompany accounts and transactions have been eliminated.

Stock Repurchase

Stock Repurchase

Other Recently Issued and Effective Authoritative Accounting Guidance

Other Recently Issued and Effective Authoritative Accounting Guidance

ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” ASU 2020-04 provides optional expedients and exceptions for accounting related to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. ASU 2020-04 applies only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform and do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. ASU 2020-04 was effective upon issuance, and based upon the amendments provided in ASU 2022-06 discussed below, can generally be applied through December 31, 2024. The adoption of ASU 2020-04 did not have a significant impact on our financial statements.

ASU 2021-01, “Reference Rate Reform (Topic 848): Scope.” ASU 2021-01 clarifies that certain optional expedients and exceptions in ASC 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. ASU 2021-01 also amends the expedients and exceptions in ASC 848 to capture the incremental consequences of the scope clarification and to tailor the existing guidance to derivative instruments affected by the discounting transition. ASU 2021-01 was effective upon issuance, and based upon the amendments provided in ASU 2022-06 discussed below, can generally be applied through December 31, 2024. The adoption of ASU 2021-01 did not have a significant impact on our financial statements.

ASU 2022-02, "Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures." ASU 2022-02 eliminates the accounting guidance for troubled debt restructurings in ASC Subtopic 310-40, Receivables - Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. ASU 2022-02 will also require that an entity disclose current-period gross charge-offs by year of origination for financial receivables and net investment leases within the scope of ASC Subtopic 326-20, Financial Instruments - Credit Losses - Measured at Amortized Cost. ASU 2022-02 became effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, though early adoption is permitted. The adoption of ASU 2022-02 did not have a significant impact on our financial statements.

ASU 2022-06, "Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848." ASU 2022-06 extends the period of time preparers can utilize the reference rate reform relief guidance provided by ASU 2020-04 and ASU 2021-01, which are discussed above. ASU 2022-06, which was effective upon issuance, defers the sunset date of this prior guidance from December 31, 2022 to December 31, 2024, after which entities will no longer be permitted to apply the relief guidance in Topic 848. The adoption of ASU 2022-06 did not have a significant impact on our financial statements.

Investment Securities

Investment Securities

Management classifies debt securities as held-to-maturity, available-for-sale, or trading based on its intent. Securities that management has the positive intent and ability to hold to maturity are classified as held-to-maturity and recorded at amortized cost, adjusted for amortization of premiums and accretion of discounts, which are recognized as adjustments to interest income using the interest method. Securities not classified as held-to-maturity or trading are classified as available-for-sale and recorded at fair value, with unrealized holding gains and losses (those for which no allowance for credit losses are recorded) reported as a component of other comprehensive income, net of tax. Management determines the appropriate classification of securities at the time of purchase.

Interest income includes amortization of purchase premiums and discounts over the period to maturity using a level-yield method, except for premiums on callable securities, which are amortized to their earliest call date. Realized gains and losses are recorded on the sale of securities in noninterest income.

The Company has made a policy election to exclude accrued interest from the amortized cost basis of securities and report accrued interest separately in other assets on the consolidated balance sheets. A security is placed on nonaccrual status at the time any principal or interest payments become more than 90 days delinquent or if full collection of interest or principal becomes uncertain. Accrued interest for a security placed on nonaccrual is reversed against interest income. There was no accrued interest related to securities reversed against interest income for the three and nine-months ended September 30, 2023 and 2022.

The Company records its available-for-sale securities portfolio at fair value. Fair values of these securities are determined based on methodologies in accordance with current authoritative accounting guidance. Fair values are volatile and may be influenced by a number of factors, including market interest rates, prepayment speeds, discount rates, credit ratings, and yield curves. Fair values for securities are based on quoted market prices, where available. If quoted market prices are not available, fair values are based on the quoted prices of similar instruments or an estimate of fair value by using a range of fair value estimates in the marketplace as a result of the illiquid market, specific to the type of security.

The Company’s investment portfolio currently consists of obligations of state and political subdivisions, mortgage pass-through securities, corporate bonds and general obligation or revenue based municipal bonds. Pricing for such securities is generally readily available and transparent in the market. The Company utilizes independent third-party pricing services to value its investment securities, which the Company reviews as well as the underlying pricing methodologies for reasonableness and to ensure such prices are aligned with pricing matrices. The Company validates prices supplied by the independent pricing services by comparison to prices obtained from other third-party sources on a quarterly basis.

Allowance for Credit Losses – Available-for-Sale Securities

Allowance for Credit Losses – Available-for-Sale Securities

For available-for-sale securities in an unrealized loss position, we first assess whether we intend to sell, or it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, any previously recognized allowances are charged-off and the security’s amortized cost basis is written down to fair value through income as a provision for credit losses. For available-for-sale securities that do not meet the aforementioned criteria, we evaluate whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis.

Management has made the accounting policy election to exclude accrued interest receivable on available-for-sale securities from the estimate of credit losses. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit losses. Available-for-sale securities are charged-off against the allowance or, in the absence of any allowance, written down through income when deemed uncollectible by management or when either of the aforementioned criteria regarding intent or requirement to sell is met.

At September 30, 2023 and 2022, and December 31, 2022, no allowance for credit losses - available-for-sale securities was recorded.

The allowance for credit losses on held-to-maturity securities is a contra-asset valuation account, calculated in accordance with ASC 326, that is deducted from the amortized cost basis of held-to-maturity securities to present management’s best estimate of the net amount expected to be collected. Held-to-maturity securities are charged-off against the allowance when deemed uncollectible by management. Adjustments to the allowance are reported in our income statement as a component of credit loss expense. Management measures expected credit losses on held-to-maturity securities on a collective basis by major security type with each type sharing similar risk characteristics and considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. Management has made the accounting policy election to exclude accrued interest receivable on held-to-maturity securities from the estimate of credit losses.

At September 30, 2023 and 2022, and December 31, 2022, the Company held no securities that were classified as held-to-maturity.

Loans Held-for-Investment

Loans Held-for-Investment

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost, net of the allowance for credit losses. Amortized cost is the principal balance outstanding, net of purchase premiums and discounts, fair value hedge accounting adjustments, deferred loan fees and costs. The Company has made a policy election to exclude accrued interest from the amortized cost basis of loans and report accrued interest separately from the related loan balance in other assets on the condensed consolidated balance sheets.

Interest on loans is calculated by using the simple interest method on daily balances of the principal amounts outstanding. The Company defers and amortizes net loan origination fees and costs as an adjustment to yield.

Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Loans are placed on nonaccrual status when, in management’s opinion, the borrower may be unable to meet payment obligations as they become due, as well as when required by regulatory provisions. In determining whether or not a borrower may be unable to meet payment obligations for each class of loans, we consider the borrower’s debt service capacity through the analysis of current financial information, if available, and/or current information with regards to our collateral position. Regulatory provisions would typically require the placement of a loan on nonaccrual status if principal or interest has been in default for a period of 90 days or more unless the loan is both well secured and in the process of collection or full payment of principal and interest is not expected. Loans may be placed on nonaccrual status regardless of whether or not such loans are considered past due. When interest accrual is discontinued, all unpaid accrued interest is reversed. Interest income on nonaccrual loans is recognized only to the extent that cash payments are received in excess of principal due. A loan may be returned to accrual status when all the principal and interest amounts contractually due are brought current and future principal and interest amounts contractually due are reasonably assured.

Further information regarding our accounting policies related to past due loans, nonaccrual loans and loans to borrowers experiencing financial difficulty is presented in Note 3.

Acquired Loans

Acquired Loans

Loans acquired in connection with acquisitions are recorded at their acquisition-date fair value. The allowance for credit losses related to the acquired loan portfolio is not carried over. Upon the adoption of ASC 326, acquired loans are classified into two categories based on the credit risk characteristics of the underlying borrowers as either purchased credit deteriorated (“PCD”) loans, or loans with no evidence of credit deterioration (“non-PCD”).

PCD loans are defined as a loan or pool of loans that have experienced more-than-insignificant credit deterioration since the origination date. The Company uses a combination of individual and pooled review approaches to determine if acquired loans are PCD. At acquisition, the Company considers a number of factors to determine if an acquired loan or pool of loans has experienced more-than-insignificant credit deterioration.

The initial allowance related to PCD loans that share similar risk characteristics is established using a pooled approach. The Company uses either a discounted cash flow or weighted average remaining life method to determine the required level of the allowance. PCD loans that were classified as nonaccrual as of the acquisition date and are collateral dependent are assessed for allowance on an individual basis. For PCD loans, an initial allowance is established on the acquisition date. Subsequent to the acquisition date, the initial allowance for credit losses on PCD loans will increase or decrease based on future evaluations, with changes recognized in the provision for credit losses.

Non-PCD loans are pooled into segments together with originated loans that share similar risk characteristics and have an allowance established on the acquisition date, which is recognized in the current period provision for credit losses as well as a fair value adjustment to the amortized cost of the loan and accreted into income over the life of the loan.

Determining the fair value of the acquired loans involves estimating the principal and interest payment cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. Management considers a number of factors in evaluating the acquisition-date fair value including the remaining life, interest rate profile, market interest rate environment, payment schedules, risk ratings, probability of default and loss given default, and estimated prepayment rates. For PCD loans, the non-credit discount or premium is allocated to individual loans as determined by the difference between the loan’s unpaid principal balance and amortized cost basis. For non-PCD loans, the fair value discount or premium is allocated to individual loans and recognized into interest income on a level yield basis over the remaining expected life of the loan.

Allowance for Credit Losses - Loans

Allowance for Credit Losses - Loans

The allowance for credit losses (“allowance” or “ACL”) is a contra-asset valuation account, calculated in accordance with ASC 326, that is deducted from the amortized cost basis of loans. The ACL represents an amount which, in management’s judgement, is adequate to absorb the lifetime expected credit losses that may be experienced on outstanding loans at the balance sheet date based on the evaluation of the size and current risk characteristics of the loan portfolio, past events, current conditions, reasonable and supportable forecasts of future economic conditions and prepayment experience. The allowance for credit losses is measured and recorded upon the initial recognition of a financial asset. Determination of the adequacy of the allowance is inherently complex and requires the use of significant and highly subjective estimates. Loans are charged-off against the allowance when deemed uncollectible by management. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Adjustments to the allowance are reported in our income statement as a component of the provision for credit losses. Management has made the accounting policy election to exclude accrued interest receivable on loans from the estimate of credit losses.

The Company’s methodology for estimating the allowance includes: (1) a collective quantified reserve that reflects the Company’s historical default and loss experience adjusted for expected economic conditions throughout a reasonable and supportable period and the Company’s prepayment and curtailment rates; (2) collective qualitative factors that consider concentrations of the loan portfolio, expected changes to the economic forecasts, large relationships, early delinquencies, and factors related to credit administrations, including, among others, loan-to-value ratios, borrowers’ risk rating and credit score migrations; and (3) individual allowances on loans where borrowers are experiencing financial difficulty or when the Company determines that the foreclosure is probable.

In calculating the allowance for credit losses, most loans are segmented into pools based upon similar characteristics and risk profiles. Common characteristics and risk profiles include the type/purpose of loan, underlying collateral, geographical similarity and historical/expected credit loss patterns. In developing these loan pools for the purposes of modeling expected credit losses, we also analyzed the degree of correlation in how loans within each portfolio respond when subjected to varying economic conditions and scenarios as well as other portfolio stress factors. For modeling purposes, our loan portfolio segments include Commercial and Industrial (“C&I”), Municipal, Agricultural, Construction and Development, Farm, Non-Owner Occupied and Owner Occupied Commercial Real Estate (“CRE”), Residential, Consumer Auto, and Consumer Non-Auto. We periodically reassess each pool to ensure the loans within the pool continue to share similar characteristics and risk profiles and to determine whether further segmentation is necessary. Refer to Note 3 for more details on the Company’s portfolio segments.

The Company applies two methodologies to estimate the allowance on its pooled portfolio segments; discounted cash flows method and weighted average remaining life method. Allowance estimates on the following portfolio segments are calculated using the discounted cash flows method: C&I, Municipal, Construction and Development, Farm, Non-Owner Occupied and Owner Occupied CRE, and Residential. Allowance estimates on the following portfolio segments are calculated using the remaining life method: Agriculture, Consumer Auto and Consumer Non-Auto. The models related to these methodologies utilize the Company’s historical default and loss experience adjusted for future economic forecasts. The reasonable and supportable forecast period represents a one-year economic outlook for the applicable economic variables. Following the end of the reasonable and supportable forecast period, expected losses revert back to the historical mean over the next two years on a straight-line basis. Economic variables that have the most significant impact on the allowance include: Texas unemployment rate, Texas house price index, and Texas retail sales index. Contractual loan level cash flows within the discounted cash flows methodology are adjusted for the Company’s historical prepayment and curtailment rate experience.

In some cases, management may determine that an individual loan exhibits unique risk characteristics which differentiate the loan from other loans within our loan pools. In such cases, the loans are evaluated for expected credit losses on an individual basis and excluded from the collective evaluation. Specific allocations of the allowance for credit losses are determined by analyzing the borrower’s ability to repay amounts owed, collateral deficiencies, the relative risk rating of the loan and economic conditions affecting the borrower’s industry, among other things. A loan is considered to be collateral dependent when, based upon management’s assessment, the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the sale of the collateral. In such cases, expected credit losses are based on the fair value of the collateral at the measurement date, adjusted for estimated selling costs if satisfaction of the loan depends on the sale of the collateral. We reevaluate the fair value of collateral supporting collateral dependent loans on an ongoing basis.

Management qualitatively adjusts model results for risk factors that are not considered within our modeling processes but are nonetheless relevant in assessing the expected credit losses within our loan pools. These qualitative factor (“Q-Factor”) adjustments may increase or decrease management’s estimate of expected credit losses by a calculated percentage or amount based upon the estimated level of risk. The various risks that may be considered in making Q-Factor adjustments include, among other things, the impact of (i) changes in lending policies and procedures, including changes in underwriting standards and practices for collections, write-offs, and recoveries, (ii) actual and expected changes in national, regional, and local economic and business conditions and developments that affect the collectability of the loan pools, (iii) changes in the nature, volume and size of a loan or the loan pools and in the terms of the underlying loans, (iv) changes in the experience, ability, and depth of our lending management and staff, (v) changes in volume and severity of past due financial assets, the volume of nonaccrual assets, and the volume and severity of adversely classified or graded assets, (vi) changes in the quality of our credit review function, (vii) changes in the value of the underlying collateral for loans that are non-collateral dependent, (viii) the existence, growth, and effect of any concentrations of credit and (ix) other factors such as the regulatory, legal and technological environments, competition, and events such as natural disasters or health pandemics.

Management believes it uses relevant information available to make determinations about the allowance and that it has established the existing allowance in accordance with GAAP. However, the determination of the allowance requires significant judgment, and estimates of expected lifetime losses in the loan portfolio can vary significantly from the amounts actually observed. While management uses available information to recognize expected losses, future additions to the allowance may be necessary based on changes in the loans comprising the portfolio, changes in the current and forecasted economic conditions, changes to the interest rate environment which may directly impact prepayment and curtailment rate assumptions, and changes in the financial condition of borrowers.

Allowance for Credit Losses - Off-Balance-Sheet/Reserve for Unfunded Commitments

Allowance for Credit Losses - Off-Balance-Sheet/Reserve for Unfunded Commitments

The allowance for credit losses on off-balance-sheet credit exposures is a liability account, calculated in accordance with ASC 326, representing expected credit losses over the contractual period for which we are exposed to credit risk resulting from a contractual obligation to extend credit. These obligations include unfunded lines of credit, commitments to extend credit and federal funds sold to correspondent banks and standby letters of credit. No allowance is recognized if we have the unconditional right to cancel the obligation. The allowance is reported as a component of accrued interest payable and other liabilities in our consolidated balance sheets. Adjustments to the allowance are reported in our income statement as a component of the provision for credit losses. At September 30, 2023 and 2022, and December 31, 2022, the Company’s reserve for unfunded commitments totaled $7,903,000, $10,879,000 and $12,323,000, respectively, which is included in other liabilities in the consolidated balance sheet.

Other Real Estate

Other Real Estate

Other real estate owned is foreclosed property held pending disposition and is initially recorded at fair value, less estimated costs to sell, and is included in other assets in the consolidated balance sheet. At foreclosure, if the fair value of the real estate, less estimated costs to sell, is less than the Company’s recorded investment in the related loan, a write-down is recognized through a charge to the allowance for credit losses. Any subsequent reduction in value is recognized by a charge to income. Operating and holding expenses of such properties, net of related income, and gains/losses on their disposition are included in net gain (loss) on sale of foreclosed assets as incurred.

Bank Premises and Equipment

Bank Premises and Equipment

Bank premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed principally on a straight-line basis over the estimated useful lives of the related assets. Leasehold improvements are amortized over the life of the respective lease or the estimated useful lives of the improvements, whichever is shorter.

Business Combinations, Goodwill and Other Intangible Assets

Business Combinations, Goodwill and Other Intangible Assets

The Company accounts for all business combinations under the purchase method of accounting. Tangible and intangible assets and liabilities of the acquired entity are recorded at fair value. Intangible assets with finite useful lives represent the future benefit associated with the acquisition of the core deposits and are amortized over seven years, utilizing a method that approximates the expected attrition of the deposits. Goodwill with an indefinite life is not amortized, but rather tested annually for impairment as of June 30 each year. There was no impairment recorded during the nine-months ended September 30, 2023 or 2022, respectively.

Securities Sold Under Agreements To Repurchase

Securities Sold Under Agreements to Repurchase

Securities sold under agreements to repurchase, which are classified as borrowings, generally mature within one to four days from the transaction date. Securities sold under agreements to repurchase are reflected at the amount of the cash received in connection with the transaction. The Company may be required to provide additional collateral based on the estimated fair value of the underlying securities.

Segment Reporting

Segment Reporting

The Company has determined that its banking regions meet the aggregation criteria of the current authoritative accounting guidance since each of its banking regions offer similar products and services, operate in a similar manner, have similar customers and report to the same regulatory authority, and therefore operate one line of business (community banking) located in a single geographic area (Texas).

Statements of Cash Flows

Statements of Cash Flows

For purposes of reporting cash flows, cash and cash equivalents includes cash on hand, amounts due from banks, including interest-bearing deposits in banks with original maturity of 90 days or less, and federal funds sold.

Accumulated Other Comprehensive Earnings (Loss)

Accumulated Other Comprehensive Earnings (Loss)

Unrealized net losses on the Company’s available-for-sale securities, net of applicable income taxes, totaled $639,934,000, $632,421,000 and $535,228,000 at September 30, 2023, and 2022, and December 31, 2022, respectively, are included in accumulated other comprehensive earnings (loss) as a separate component of shareholders' equity.

Income Taxes

Income Taxes

The Company’s provision for income taxes is based on income before income taxes adjusted for permanent differences between financial reporting and taxable income. Deferred tax assets and liabilities are determined using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. As of September 30, 2023, and 2022, and December 31, 2022, deferred tax assets totaled $173,032,000, $168,398,000 and $145,511,000, respectively, and were included in other assets on the consolidated balance sheets.

Stock Based Compensation

Stock Based Compensation

The Company grants stock options for a fixed number of shares to employees with an exercise price equal to the fair value using the Black-Scholes model of the shares at the grant date. The grant date fair value is amortized over the vesting period which generally is three, five or six years. The Company also grants restricted stock and/or units for a fixed number of shares which generally vests over periods of one to three years, and performance stock units which vest over a 3-year period based on Company performance metrics relative to a defined peer group. For stock option grants, the exercise price is established based on the closing trading price. No adjustments have been necessary to properly value the grant based on the terms or other conditions of the grants. Expense is recognized based on the fair value of the portion of stock-based payment awards that ultimately expected to vest, reduced for forfeitures based on grant-date fair value. See Note 8 for further information.

Advertising Costs

Advertising Costs

Advertising costs are expensed as incurred.

Per Share Data

Per Share Data

Net earnings per share (“EPS”) are computed by dividing net earnings by the weighted average number of common shares outstanding during the period. The Company calculates dilutive EPS assuming all outstanding stock options to purchase common shares and unvested restricted stock shares and units have been exercised and/or vested at the beginning of the year (or the time of issuance, if later.) The dilutive effect of the outstanding options and restricted stock is reflected by application of the treasury stock method, whereby the proceeds from the exercised options and unearned compensation for both restricted stock and stock options are assumed to be used to purchase common shares at the average market price during the respective period. There were 864,000 and 478,000 anti-dilutive shares for the three and nine-months ended September 30, 2023, respectively, that were excluded from the computation of EPS. There were 346,000 and 272,000 anti-dilutive shares for the three and nine-months ended September 30, 2022, respectively, that were excluded from the computation of EPS. The following table reconciles the computation of basic EPS to diluted EPS:
