Accounting Policies [Abstract]
Description of Business and Summary of Significant Accounting Policies	(1) DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The accounting and reporting policies of BancFirst Corporation and its subsidiaries (the “Company”) conform to accounting principles generally accepted in the United States of America (U.S. GAAP) and general practice within the banking industry. A summary of the significant accounting policies follows. Nature of Operations BancFirst Corporation is an Oklahoma business corporation and a financial holding company under federal law. It conducts virtually all of its operating activities through its principal wholly-owned subsidiary, BancFirst (“BancFirst”), an Oklahoma state-chartered bank headquartered in Oklahoma City, Oklahoma. The Company also conducts operating activities through its wholly-owned subsidiaries, Pegasus Bank (“Pegasus”), a Texas state-chartered bank headquartered in Dallas, Texas and Worthington Bank ("Worthington"), a Texas state-chartered bank headquartered in Arlington, Texas. BancFirst, Pegasus and Worthington provide a wide range of retail and commercial banking services, including: commercial, real estate, agricultural and consumer lending; depository and funds transfer services; collections; safe deposit boxes; cash management services; and other services tailored for both individual and corporate customers. BancFirst also offers trust services and acts as executor, administrator, trustee, transfer agent and in various other fiduciary capacities. BancFirst provides item processing, research and other correspondent banking services to financial institutions and governmental units. The Company’s wholly-owned subsidiary, BancFirst Insurance Services, Inc., an independent insurance agency, offers a variety of commercial and personal insurance products. In addition, the Company’s wholly-owned subsidiary, Council Oak Partners, LLC, an Oklahoma limited liability company, engages in investing activities. Basis of Presentation The accompanying consolidated financial statements include the accounts of BancFirst Corporation, Council Oak Partners, LLC, BancFirst Insurance Services, Inc., Pegasus, Worthington and BancFirst and its subsidiaries. The principal operating subsidiaries of BancFirst are BFTower, LLC, BFC-PNC LLC, BF Brazito, LLC, and BancFirst Agency, Inc. All significant intercompany accounts and transactions have been eliminated. Assets held in a fiduciary or agency capacity are not assets of the Company and, accordingly, are not included in the consolidated financial statements. Certain amounts from 2021 and 2020 have been reclassified to conform to the 2022 presentation. These reclassifications were not material to the Company’s consolidated financial statements. Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with U.S. GAAP inherently involves the use of estimates and assumptions that affect the amounts reported in the financial statements and the related disclosures. These estimates relate principally to the determination of the allowance for credit losses, income taxes, the fair value of financial instruments and the valuation of assets and liabilities acquired in a business combination, including identifiable intangible assets. Such estimates and assumptions may change over time and actual amounts realized may differ from those reported. Securities The Company invests in debt securities. Any sales of debt securities are for the purpose of executing the Company’s asset/liability management strategy, eliminating a perceived credit risk in a specific security or providing liquidity. Debt securities that are being held for indefinite periods of time, or that may be sold as part of the Company’s asset/liability management strategy, to provide liquidity or for other reasons, are classified as available for sale and are stated at estimated fair value. Unrealized gains or losses on debt securities available for sale are reported as a component of stockholders’ equity, net of income tax. Gains or losses from sales of debt securities are based upon the book values of the specific debt securities sold. Debt securities for which the Company has the intent and ability to hold to maturity are classified as held for investment and are stated at cost, adjusted for amortization of premiums and accretion of discounts computed under the interest method. The Company reviews its portfolio of debt securities in an unrealized loss position at least quarterly. The Company first assesses whether it intends to sell or it is more-likely-than-not that it will be required to sell the securities before recovery of the amortized cost basis. If either of these criteria is met, the securities amortized cost basis is written down to fair value as a current period expense. If either of the above criteria is not met, the Company evaluates whether the decline in fair value is the result of credit losses or other factors. In making this assessment, the Company considers, among other things, the performance of any underlying collateral and adverse conditions specifically related to the security. The Company does not consider the unrealized position of its debt securities to be the result of credit factors, because the decline in fair value is attributable to changes in interest rates and illiquidity, and not credit quality, and the Company does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery. Therefore, the Company has not recorded an allowance for credit losses against its debt securities portfolio, as the credit risk is not material. The Company does not engage in securities trading activities. The Company invests in equity securities without readily determinable fair values and utilizes Level 3 inputs. These securities are reported at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. The realized and unrealized gains and losses are reported as securities transactions in the noninterest income section of the consolidated statements of comprehensive income. Equity securities are reported in other assets on the consolidated balance sheet. The Company reviews its portfolio of equity securities for impairment at least quarterly. Loans The lending function is governed by written policies and procedures, as determined by senior management and approved by the Board of Directors. The policies and procedures set the standards for lending in each major loan category by collateral type and use of loan proceeds. The objectives of these policies and procedures are to identify profitable markets, determine appropriate risk tolerance levels for each type of loan, establish limits for loan officer approval, set concentration limits, establish loan-to-value thresholds, set repayment terms and loan structure guidelines and adhere to documentation requirements. Interest rate risk is controlled by the use of variable rate provisions, the vast majority of which have a rate floor, limits on fixing rates for longer periods and the use of prepayment penalties. Loans originated within the Company are stated at the principal amount outstanding, net of unearned interest, loan fees and allowance for credit losses. Interest on all performing loans is recognized, on a simple interest basis, based upon the principal amount outstanding. See Note (5) for loan disclosures. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost. Amortized cost is the principal balance outstanding, net of purchase premiums and discounts. The Company has made the accounting policy election to exclude accrued interest receivable on loans from the estimate of credit losses because it writes off uncollectible accrued interest in a timely manner. Interest income is accrued on the unpaid principal balance using the simple-interest method on the daily balances of the principal amounts outstanding. The Company writes off accrued interest once a loan enters non-accrual status. The Company debits interest income for the interest accrued. No interest will be accrued on loans, for which a default of principal or interest has existed for a period of at least 90 days unless the collateral margin or guarantor support are such that full collection of principal and interest are not in doubt and an orderly plan for collection is in process. The Company also suspends interest recognition on any other loan for which it is more likely than not that future contractual payments will not be collected. Interest income on consumer and commercial loans is discontinued and placed on nonaccrual status at the time the loan is 90 days delinquent unless the loan is well secured and in process of collection. Consumer loans are charged off at 180 days past due and commercial loans are charged off to the extent principal or interest is deemed uncollectible. Past-due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. The amount of interest accrued but not received for loans placed on nonaccrual and reversed against interest income was $147,000, $83,000 and $841,000 million for the years ended December 31, 2022, 2021 and 2020, respectively. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Under the cost-recovery method, interest income is not recognized until the loan balance is reduced to zero. Under the cash-basis method, interest income is recorded when the payment is received in cash. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Troubled debt restructurings are loans on which, due to the borrower’s financial difficulties, the Company has granted a concession that the Company would not otherwise consider for borrowers of similar credit quality. This may include a transfer of real estate or other assets from the borrower, a modification of loan terms, or a combination of the two. Modifications of terms that could potentially qualify as a restructuring include reduction of contractual interest rate, extension of the maturity date at a contractual interest rate lower than the current rate for new debt with similar risk, and a reduction of the face amount of debt or forgiveness of either principal or accrued interest. A loan continues to qualify as restructured until a consistent payment history or change in the borrower’s financial condition has been evidenced, generally for no less than twelve months. If the restructuring agreement specifies an interest rate at the time of the restructuring that is greater than or equal to the rate that the Company is willing to accept for a new extension of credit with comparable risk, then the loan is no longer considered a restructured loan if it is in compliance with the modified terms in calendar years after the year of restructure. Residential real estate loans are made in accordance with underwriting policies and are fully documented. Credit worthiness is assessed based on significant credit characteristics including credit history and residential and employment stability. The Company does not engage in any hybrid loan programs. In addition, the Company does not have any exposure to loans with negative amortization, interest rate carryover or discounting of the initial rates (teaser rates). An updated appraisal of the collateral is obtained when a loan is first identified as a problem loan. Appraisals are reviewed annually and are updated as needed or are updated more frequently if significant changes are believed to have occurred in the collateral or market conditions. Appraisals of other real estate owned are also reviewed and updated consistent with this policy. When a loan deteriorates to the point that the account officer or the Loan Committee concludes it no longer represents a viable asset, it will be charged off. Similarly, any portion of a loan that is deemed to no longer be a viable asset will be charged off. A loan will not be charged off unless such action has been approved by the branch President. Acquired Loans Loans acquired through business combinations are required to be carried at fair value as of the date of the combination. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date. The methodology of allowance for credit loss recorded for these acquired loans depends on whether the acquired loans are purchase credit deteriorated or non-purchase credit deteriorated. An allowance for credit loss for non-purchase credit deteriorated loans is determined and recorded in a manner consistent with originated loans. That is, the allowance for credit loss is calculated based on the loan’s amortized cost basis (i.e., the acquisition date fair value in a business combination) and is established through a charge to provision expense at the acquisition date. An allowance for credit loss for purchase credit deteriorated loans is recorded as an adjustment to the loans, in addition to the fair value amount recorded, as of the acquisition date, and not through provision expense. The acquisition date fair value plus the allowance for credit loss equals the loans new amortized cost basis as of the acquisition date. The difference between the new amortized cost basis and the unpaid principal balance of the loan represents the non-credit purchase discount/premium recorded. The difference between the fair value of loans which do not have specific evidence of deterioration of credit quality since origination and their principal balance is recognized in interest income on a level-yield method over the life of the loans. For loans which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments (as determined by the present value of expected future cash flows), the difference between the undiscounted cash flows expected at acquisition and the investment in the loan, or the “accretable yield,” is recognized in interest income on a level-yield method over the life of the loan. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition, or the “nonaccretable difference,” are not recognized as yield adjustments or as loss accruals or valuation allowances. Increases in expected cash flows subsequent to the initial investment are recognized prospectively through adjustment of the yield on the loan over its remaining life. Decreases in expected cash flows are recognized as impairments. Any probable loss due to subsequent credit deterioration of the loans since acquisition is provided for in the allowance for credit losses. Purchased Credit Deteriorated (PCD) Loans The Company has purchased loans, some of which have experienced more than insignificant credit deterioration since origination. An allowance for credit losses is determined using the same methodology as other loans held for investment. The initial allowance for credit losses determined on a collective basis is allocated to individual loans. The sum of the loan’s purchase price and allowance for credit losses becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the allowance for credit losses are recorded through provision expense. Loans Held for Sale The Company originates mortgage loans to be sold. At the time of origination, the acquiring bank has already been determined and the terms of the loan, including the interest rate, have already been set by the acquiring bank allowing the Company to originate the loan at fair value. Mortgage loans are generally sold within 30 days of origination. Loans held for sale are carried at the lower of cost or fair value. Gains or losses recognized upon the sale of the loans are determined on a specific identification basis. The Company does not sell residential mortgage loans with recourse other than obligations under standard representations and warranties or for fraud. These obligations relate to loan performance for the life of the loan. The amount of loans repurchased since the inception of the program is not considered to be material, and therefore, no reserve has been required. Allowance for Credit Losses The allowance for credit losses is a valuation account that is deducted from the loans amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged off against the allowance when management believes the uncollectibility of a loan balance is confirmed. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. The allowance for credit losses is increased by provisions charged to operating expense and is reduced by net loan charge-offs. The Company considers various factors to monitor the credit risk in the loan portfolio including volume and severity of loan delinquencies, nonaccrual loans, internal grading of loans, historical loan loss experience and economic conditions. Management estimates the allowance balance using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level, or term as well as for changes in environmental conditions, such as the political, legal, and regulatory environment, technology and consumer preferences. Historical loss information is also adjusted for reasonable and supportable changes in national and local economic conditions, such as consumer loans 90 days past due and commercial bankruptcies. Economic conditions are forecast as "current conditions" over the forecast period. Forecast models were used to validate credit performance during the forecast period. Beyond the reasonable and supportable forecast, the economic expectation reverts to the historical average, which is determined by the weighted average life of each loan pool. If a loan is individually evaluated a specific allowance is provided, if necessary, so that the loan is reported net, at the fair value of collateral. Interest payments on collateral dependent loans are typically applied to principal unless collectability of the principal amount is reasonably assured, in which case interest is recognized on a cash basis. Loans, or portions thereof, are charged off when deemed uncollectible. The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist. Determining the Contractual Term Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a troubled debt restructuring will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by the Company. Troubled Debt Restructurings (TDRs) The allowance for credit loss on a TDR is measured using the same method as all other loans held for investment, except when the value of a concession cannot be measured using a method other than the discounted cash flow method. When the value of a concession is measured using the discounted cash flow method, the allowance for credit loss is determined by discounting the expected future cash flows at the original interest rate of the loan. Allowance for Credit Losses on Off-Balance Sheet Credit Exposures The Company estimates expected credit losses over the contractual period in which the Company is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. The allowance for credit losses on off-balance sheet credit exposures is adjusted as a provision for credit loss expense. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life. Based on a low likelihood that funding will occur and the Company’s ability to manage the extension of credit to our borrowers, the allowance for credit losses on off-balance sheet credit exposure is not material. Allowance for Credit Losses on Available-for-Sale Debt Securities The Company reviews its portfolio of debt securities in an unrealized loss position at least quarterly. The Company first assesses whether it intends to sell or it is more-likely-than-not that it will be required to sell the securities before recovery of the amortized cost basis. If either of these criteria is met, the securities amortized cost basis is written down to fair value as a current period expense. If either of the above criteria is not met, the Company evaluates whether the decline in fair value is the result of credit losses or other factors. In making this assessment, the Company considers, among other things, the performance of any underlying collateral and adverse conditions specifically related to the security. At December 31, 2022 and December 31, 2021 approximately 98% of the available for sale debt securities held by the Company were issued by the U.S. Treasury, or U.S. government-sponsored entities and agencies. The Company does not consider the unrealized loss position of these securities to be the result of credit factors, because the decline in fair value is attributable to changes in interest rates and illiquidity, and not credit quality, and the Company does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery. Therefore, the Company has not recorded an allowance for credit losses against its debt securities portfolio, as the credit risk is not material. PPP Fee Income Policy The Paycheck Protection Program (“PPP”), established as part of the Coronavirus Aid, Relief and Economic Security (“CARES”) Act, provided that the Small Business Administration ("SBA") would pay processing fees of up to 5% to lenders based on the volume of the PPP loans disbursed. The fee was based on the balance of each PPP loan outstanding at the time of full disbursement. The Company received processing fees from the SBA of $23.8 million in 2021 and $30.2 million in 2020. The unamortized balance of these fees on each loan is reported on the Company's consolidated balance sheet as part of the loan balance to which it relates and is recognized over the remaining life of the loan as an adjustment of yield. The unamortized balances of these fees was $0 and $2.0 million for the year ended December 31, 2022 and 2021, respectively. Nonaccrual Policy A loan is placed on nonaccrual status when, in the opinion of management, the future collectability of both interest and principal is not probable. When interest accrual is discontinued, all unpaid accrued interest is reversed. Interest income is recognized on certain of these loans on a cash basis if the full collection of the remaining principal balance is reasonably expected. Otherwise, interest income is not recognized until the principal balance is fully collected. The Company does not accrue interest on (1) any loan upon which a default of principal or interest has existed for a period of 90 days or over unless the collateral margin or guarantor support are such that full collection of principal and interest are not in doubt, and an orderly plan for collection is in process; and (2) any other loan for which it is expected full collection of principal and interest is not probable. A nonaccrual loan may be restored to an accrual status when none of its principal and interest are past due and unpaid or otherwise becomes well secured and in the process of collection and when prospects for collection of future contractual payments are no longer in doubt. With the exception of a formal debt forgiveness agreement, no loan which has had principal charged-off shall be restored to accrual status unless the charged-off principal has been recovered. Premises and Equipment Premises and equipment are stated at cost, less accumulated depreciation. Depreciation is charged to operating expense and is computed using the straight-line method over the estimated useful lives of the assets. Maintenance and repairs are charged to expense as incurred while improvements are capitalized. Premises and equipment is tested for impairment if events or changes in circumstances occur that indicate that the carrying amount of any premises and equipment may not be recoverable. Impairment losses are measured by comparing the fair values of the premises and equipment with their recorded amounts. Premises that are identified to be sold are transferred to other real estate owned at the lower of their carrying amounts or their fair values less estimated costs to sell. Any losses on premises identified to be sold are charged to operating expense. When premises and equipment are transferred to other real estate owned, sold, or otherwise retired, the cost and applicable accumulated depreciation are removed from the respective accounts and any resulting gains or losses are reported in the consolidated statement of comprehensive income. Construction in progress includes all the costs of construction associated with the building of fixed long-term assets and is included in premises and equipment, net as an asset. When construction is completed, the asset is reclassified as a building or a leasehold improvement and depreciated over its applicable useful life. Leases Certain operating leases are included as right of use lease assets in accrued interest receivable and other assets on the consolidated balance sheet and a related lease liability is included in accrued interest payable and other liabilities on the consolidated balance sheet. Right of use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. The lease liability is measured as the present value of the unpaid lease payments, and the right of use assets value is derived from the calculation of the lease liability. To calculate the discount rate for each lease, the Company uses the rate implicit in the lease if available, otherwise an appropriate Federal Home Loan Bank ("FHLB") advance borrowing rate is used that correlates with the term of the lease. Other Real Estate Owned Other real estate owned ("OREO") consists of properties acquired through foreclosure proceedings or acceptance of a deed in lieu of foreclosure, and premises held for sale. These properties are carried at the lower of the book values of the related loans or fair values based upon appraisals, less estimated costs to sell. Losses arising at the time of reclassification of such properties from loans to OREO are charged directly to the allowance for credit losses. Any losses on premises identified to be sold are charged to operating expense at the time of transfer from premises to OREO. Losses from declines in value of the properties subsequent to classification as OREO are charged to operating expense. Revenues and expenses for OREO property are included in the consolidated statement of comprehensive income for the period in which they occur. Gross rental income for OREO is included in other non-interest income. The expenses of operating or holding OREO property are included in noninterest expense. Intangible Assets and Goodwill Core deposit intangibles are amortized on a straight-line basis over the estimated useful lives of seven to ten years and customer relationship intangibles are amortized on a straight-line basis over the estimated useful life of three to eighteen years. Goodwill is not amortized but is evaluated at a reporting unit level at least annually for impairment, or more frequently if other indicators of impairment are present. At least annually in the fourth quarter, intangible assets are evaluated for possible impairment. Impairment losses are measured by comparing the fair values of the intangible assets with their recorded amounts. Any impairment losses are reported in the consolidated statement of comprehensive income. Advertising Costs Advertising costs are expensed as incurred. Advertising costs for the year ended December 31, 2022 were $3.0 million. Advertising costs for the years ended December 31, 2021 and 2020 were $3.0 million and $3.3 million, respectively. Stock-based Compensation The Company recognizes stock-based compensation as compensation expense in the consolidated statement of comprehensive income based on the fair value of the Company’s stock options on the measurement date, which, for the Company, is the date of the grant. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model and is based on certain assumptions including risk-free rate of return, dividend yield, stock price volatility and the expected term. The fair value of each option is expensed over its vesting period. Income Taxes The Company files a consolidated income tax return with its subsidiaries. Federal and state income tax expense or benefit has been allocated to subsidiaries on a separate return basis. Deferred taxes are recognized under the balance sheet method based upon the future tax consequences of temporary differences between the carrying amounts and tax basis of assets and liabilities, using the tax rates expected to apply to taxable income in the periods when the related temporary differences are expected to be realized. Realization of deferred tax assets is dependent upon the generation of a sufficient level of future taxable income and recoverable taxes paid in prior years. Although realization is not assured, management believes it is more likely than not that all of the deferred tax assets will be realized. Earnings Per Common Share Basic earnings per common share is computed by dividing net income, less any preferred dividends requirement, by the weighted average of common shares outstanding. Diluted earnings per common share reflects the potential dilution that could occur if options, convertible securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the Company. Revenue Recognition In addition to lending and related activities, the Company offers various services to customers that generate revenue. Contract performance typically occurs in one year or less. Incremental costs of obtaining a contract are expensed when incurred when the amortization period is one year or less. Sales of real estate The sale of real estate property is generally recognized, along with any associated gain or loss, when control of the property transfers to the buyer. Service and transaction fees on depository accounts Customers often pay certain fees to the bank to access the cash on deposit including certain non-transactional fees such as account maintenance or dormancy fees, and certain transaction-based fees such as non-sufficient funds fees, overdraft, ATM, wire transfer, or foreign exchange fees. Revenue is recognized when the transactions occur or as services are performed over primarily monthly or quarterly periods. Payment is typically received in the period the transactions occur, or in some cases, within 90 days of the service period. Interchange Fees Interchange fees, or “swipe” fees, are charges that merchants pay to the processors who, in turn, share that revenue with us and other card-issuing banks for processing electronic payment transactions. Interchange fees represent the portion of the debit card transaction amount that the card issuer retains to compensate it for processing transactions and providing rewards. Interchange fees are settled and recognized on a daily or monthly basis. Insurance Commissions and Fees Insurance commissions are received on the sale of insurance products, and revenue is recognized upon the placement date of the insurance policies or when such commissions are received. Payment is normally received within the policy period. In addition to placement, the Company also provides insurance policy related risk management services. Revenue is recognized as these services are provided. Performance-based commissions are recognized when received or earlier when, upon consideration of past results and current condition, the revenue is deemed not probable of reversal. For accounts billed by BancFirst Insurance Services, Inc., commission revenue is recognized at the later of the billing date or the effective date of the related insurance policies. Commission revenue, for accounts that are directly billed by the insurance company to the insured, is recognized when determinable by BancFirst Insurance Services, Inc., which is generally when such commissions are received. BancFirst Insurance Services, Inc. also receives contingent commissions from insurance companies as additional incentive for achieving specified premium volume goals and/or loss experience parameters relating to the insurance they place. Contingent commissions from insurance companies are recognized when determinable, which is generally when such commissions are received. Trust BancFirst offers trust services and acts as executor, administrator, trustee, transfer agent and in various other fiduciary capacities. There are four basic types of fees that are included in the trust department income. Administrative fees are assessed for managing trust accounts. Shareholder fees are received in connection with holding specific fund share classes. In return for these services, the mutual fund (or its distributor or investment advisor) pay a fee to BancFirst. Oil and gas fees are assessed for management of oil and gas related activities. There are also other types of fees charged on a one time basis such as those related to opening and closing trust accounts. BancFirst records trust fees on a monthly, quarterly or annual basis based on the size of the asset being managed. Fees may be fixed or, where applicable, based on a percentage of transaction size of managed assets. These fees are recorded as revenue at the time the fee is billed, according to the agreement with the customer. Comprehensive Income Comprehensive income includes all changes in stockholders’ equity during a period, except those resulting from transactions with stockholders. Besides net income, other components of the Company’s comprehensive income includes the after tax effect of changes in the net unrealized gain/loss on debt securities available for sale. The Company’s policy is to release material stranded tax effects included in accumulated other comprehensive income on a specific identification basis. Consolidated Statement of Cash Flows For purposes of the consolidated statement of cash flows, the Company considers cash and due from banks and interest-bearing deposits with banks as cash equivalents. Recent Accounting Pronouncements Standards Not Yet Adopted: In March 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2022-02, “Financial Instruments – Credit Losses (Topic 326).” ASU 2022-02 eliminates the TDR recognition and measurement guidance and, instead, requires that the Company evaluate, based on the accounting for loan modifications, whether the modification represents a new loan or a continuation of an existing loan. The Company has the option to apply a modified retrospective transition method, resulting in a cumulative-effect adjustment to retained earnings when adopted. In addition, the update requires that the Company disclose current-period write-offs by year of origination for financing receivables. The current-period write-off amendment should be applied prospectively. The amendments are effective for annual periods beginning after December 15, 2022, including interim periods within those annual periods. ASU 2022-02 will be effective for the Company on January 1, 2023. The adoption of ASU No. 2022-02 is not expected to have a significant impact on the Company’s consolidated financial statements.

Description of Business and Summary of Significant Accounting Policies

(1) DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accounting and reporting policies of BancFirst Corporation and its subsidiaries (the “Company”) conform to accounting principles generally accepted in the United States of America (U.S. GAAP) and general practice within the banking industry. A summary of the significant accounting policies follows.

Nature of Operations

BancFirst Corporation is an Oklahoma business corporation and a financial holding company under federal law. It conducts virtually all of its operating activities through its principal wholly-owned subsidiary, BancFirst (“BancFirst”), an Oklahoma state-chartered bank headquartered in Oklahoma City, Oklahoma. The Company also conducts operating activities through its wholly-owned subsidiaries, Pegasus Bank (“Pegasus”), a Texas state-chartered bank headquartered in Dallas, Texas and Worthington Bank ("Worthington"), a Texas state-chartered bank headquartered in Arlington, Texas. BancFirst, Pegasus and Worthington provide a wide range of retail and commercial banking services, including: commercial, real estate, agricultural and consumer lending; depository and funds transfer services; collections; safe deposit boxes; cash management services; and other services tailored for both individual and corporate customers. BancFirst also offers trust services and acts as executor, administrator, trustee, transfer agent and in various other fiduciary capacities. BancFirst provides item processing, research and other correspondent banking services to financial institutions and governmental units. The Company’s wholly-owned subsidiary, BancFirst Insurance Services, Inc., an independent insurance agency, offers a variety of commercial and personal insurance products. In addition, the Company’s wholly-owned subsidiary, Council Oak Partners, LLC, an Oklahoma limited liability company, engages in investing activities.

Basis of Presentation

The accompanying consolidated financial statements include the accounts of BancFirst Corporation, Council Oak Partners, LLC, BancFirst Insurance Services, Inc., Pegasus, Worthington and BancFirst and its subsidiaries. The principal operating subsidiaries of BancFirst are BFTower, LLC, BFC-PNC LLC, BF Brazito, LLC, and BancFirst Agency, Inc. All significant intercompany accounts and transactions have been eliminated. Assets held in a fiduciary or agency capacity are not assets of the Company and, accordingly, are not included in the consolidated financial statements. Certain amounts from 2021 and 2020 have been reclassified to conform to the 2022 presentation. These reclassifications were not material to the Company’s consolidated financial statements.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with U.S. GAAP inherently involves the use of estimates and assumptions that affect the amounts reported in the financial statements and the related disclosures. These estimates relate principally to the determination of the allowance for credit losses, income taxes, the fair value of financial instruments and the valuation of assets and liabilities acquired in a business combination, including identifiable intangible assets. Such estimates and assumptions may change over time and actual amounts realized may differ from those reported.

Securities

The Company invests in debt securities. Any sales of debt securities are for the purpose of executing the Company’s asset/liability management strategy, eliminating a perceived credit risk in a specific security or providing liquidity. Debt securities that are being held for indefinite periods of time, or that may be sold as part of the Company’s asset/liability management strategy, to provide liquidity or for other reasons, are classified as available for sale and are stated at estimated fair value. Unrealized gains or losses on debt securities available for sale are reported as a component of stockholders’ equity, net of income tax. Gains or losses from sales of debt securities are based upon the book values of the specific debt securities sold. Debt securities for which the Company has the intent and ability to hold to maturity are classified as held for investment and are stated at cost, adjusted for amortization of premiums and accretion of discounts computed under the interest method. The Company reviews its portfolio of debt securities in an unrealized loss position at least quarterly. The Company first assesses whether it intends to sell or it is more-likely-than-not that it will be required to sell the securities before recovery of the amortized cost basis. If either of these criteria is met, the securities amortized cost basis is written down to fair value as a current period expense. If either of the above criteria is not met, the Company evaluates whether the decline in fair value is the result of credit losses or other factors. In making this assessment, the Company considers, among other things, the performance of any underlying collateral and adverse conditions specifically related to the security. The Company does not consider the unrealized position of its debt securities to be the result of credit factors, because the decline in fair value is attributable to changes in interest rates and illiquidity, and not credit quality, and the Company does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery. Therefore, the Company has not recorded an allowance for

credit losses against its debt securities portfolio, as the credit risk is not material. The Company does not engage in securities trading activities.

The Company invests in equity securities without readily determinable fair values and utilizes Level 3 inputs. These securities are reported at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. The realized and unrealized gains and losses are reported as securities transactions in the noninterest income section of the consolidated statements of comprehensive income. Equity securities are reported in other assets on the consolidated balance sheet. The Company reviews its portfolio of equity securities for impairment at least quarterly.

Loans

The lending function is governed by written policies and procedures, as determined by senior management and approved by the Board of Directors. The policies and procedures set the standards for lending in each major loan category by collateral type and use of loan proceeds. The objectives of these policies and procedures are to identify profitable markets, determine appropriate risk tolerance levels for each type of loan, establish limits for loan officer approval, set concentration limits, establish loan-to-value thresholds, set repayment terms and loan structure guidelines and adhere to documentation requirements. Interest rate risk is controlled by the use of variable rate provisions, the vast majority of which have a rate floor, limits on fixing rates for longer periods and the use of prepayment penalties.

Loans originated within the Company are stated at the principal amount outstanding, net of unearned interest, loan fees and allowance for credit losses. Interest on all performing loans is recognized, on a simple interest basis, based upon the principal amount outstanding. See Note (5) for loan disclosures.

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost. Amortized cost is the principal balance outstanding, net of purchase premiums and discounts. The Company has made the accounting policy election to exclude accrued interest receivable on loans from the estimate of credit losses because it writes off uncollectible accrued interest in a timely manner. Interest income is accrued on the unpaid principal balance using the simple-interest method on the daily balances of the principal amounts outstanding.

The Company writes off accrued interest once a loan enters non-accrual status. The Company debits interest income for the interest accrued. No interest will be accrued on loans, for which a default of principal or interest has existed for a period of at least 90 days unless the collateral margin or guarantor support are such that full collection of principal and interest are not in doubt and an orderly plan for collection is in process. The Company also suspends interest recognition on any other loan for which it is more likely than not that future contractual payments will not be collected.

Interest income on consumer and commercial loans is discontinued and placed on nonaccrual status at the time the loan is 90 days delinquent unless the loan is well secured and in process of collection. Consumer loans are charged off at 180 days past due and commercial loans are charged off to the extent principal or interest is deemed uncollectible. Past-due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date if collection of principal or interest is considered doubtful.

All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. The amount of interest accrued but not received for loans placed on nonaccrual and reversed against interest income was $147,000, $83,000 and $841,000 million for the years ended December 31, 2022, 2021 and 2020, respectively. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Under the cost-recovery method, interest income is not recognized until the loan balance is reduced to zero. Under the cash-basis method, interest income is recorded when the payment is received in cash. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Troubled debt restructurings are loans on which, due to the borrower’s financial difficulties, the Company has granted a concession that the Company would not otherwise consider for borrowers of similar credit quality. This may include a transfer of real estate or other assets from the borrower, a modification of loan terms, or a combination of the two. Modifications of terms that could potentially qualify as a restructuring include reduction of contractual interest rate, extension of the maturity date at a contractual interest rate lower than the current rate for new debt with similar risk, and a reduction of the face amount of debt or forgiveness of either principal or accrued interest. A loan continues to qualify as restructured until a consistent payment history or change in the borrower’s financial condition has been evidenced, generally for no less than twelve months. If the restructuring agreement specifies an interest rate at the time of the restructuring that is greater than or equal to the rate that the Company is willing to accept for a new extension of credit with

comparable risk, then the loan is no longer considered a restructured loan if it is in compliance with the modified terms in calendar years after the year of restructure.

Residential real estate loans are made in accordance with underwriting policies and are fully documented. Credit worthiness is assessed based on significant credit characteristics including credit history and residential and employment stability. The Company does not engage in any hybrid loan programs. In addition, the Company does not have any exposure to loans with negative amortization, interest rate carryover or discounting of the initial rates (teaser rates).

An updated appraisal of the collateral is obtained when a loan is first identified as a problem loan. Appraisals are reviewed annually and are updated as needed or are updated more frequently if significant changes are believed to have occurred in the collateral or market conditions. Appraisals of other real estate owned are also reviewed and updated consistent with this policy.

When a loan deteriorates to the point that the account officer or the Loan Committee concludes it no longer represents a viable asset, it will be charged off. Similarly, any portion of a loan that is deemed to no longer be a viable asset will be charged off. A loan will not be charged off unless such action has been approved by the branch President.

Acquired Loans

Loans acquired through business combinations are required to be carried at fair value as of the date of the combination. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date. The methodology of allowance for credit loss recorded for these acquired loans depends on whether the acquired loans are purchase credit deteriorated or non-purchase credit deteriorated. An allowance for credit loss for non-purchase credit deteriorated loans is determined and recorded in a manner consistent with originated loans. That is, the allowance for credit loss is calculated based on the loan’s amortized cost basis (i.e., the acquisition date fair value in a business combination) and is established through a charge to provision expense at the acquisition date. An allowance for credit loss for purchase credit deteriorated loans is recorded as an adjustment to the loans, in addition to the fair value amount recorded, as of the acquisition date, and not through provision expense. The acquisition date fair value plus the allowance for credit loss equals the loans new amortized cost basis as of the acquisition date. The difference between the new amortized cost basis and the unpaid principal balance of the loan represents the non-credit purchase discount/premium recorded. The difference between the fair value of loans which do not have specific evidence of deterioration of credit quality since origination and their principal balance is recognized in interest income on a level-yield method over the life of the loans. For loans which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments (as determined by the present value of expected future cash flows), the difference between the undiscounted cash flows expected at acquisition and the investment in the loan, or the “accretable yield,” is recognized in interest income on a level-yield method over the life of the loan. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition, or the “nonaccretable difference,” are not recognized as yield adjustments or as loss accruals or valuation allowances. Increases in expected cash flows subsequent to the initial investment are recognized prospectively through adjustment of the yield on the loan over its remaining life. Decreases in expected cash flows are recognized as impairments. Any probable loss due to subsequent credit deterioration of the loans since acquisition is provided for in the allowance for credit losses.

Purchased Credit Deteriorated (PCD) Loans

The Company has purchased loans, some of which have experienced more than insignificant credit deterioration since origination. An allowance for credit losses is determined using the same methodology as other loans held for investment. The initial allowance for credit losses determined on a collective basis is allocated to individual loans. The sum of the loan’s purchase price and allowance for credit losses becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the allowance for credit losses are recorded through provision expense.

Loans Held for Sale

The Company originates mortgage loans to be sold. At the time of origination, the acquiring bank has already been determined and the terms of the loan, including the interest rate, have already been set by the acquiring bank allowing the Company to originate the loan at fair value. Mortgage loans are generally sold within 30 days of origination. Loans held for sale are carried at the lower of cost or fair value. Gains or losses recognized upon the sale of the loans are determined on a specific identification basis. The Company does not sell residential mortgage loans with recourse other than obligations under standard representations and warranties or for fraud. These obligations relate to loan performance for the life of the loan. The amount of loans repurchased since the inception of the program is not considered to be material, and therefore, no reserve has been required.

Allowance for Credit Losses

The allowance for credit losses is a valuation account that is deducted from the loans amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged off against the allowance when management believes the uncollectibility of a loan balance is confirmed. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. The allowance for credit losses is increased by provisions charged to operating expense and is reduced by net loan charge-offs.

The Company considers various factors to monitor the credit risk in the loan portfolio including volume and severity of loan delinquencies, nonaccrual loans, internal grading of loans, historical loan loss experience and economic conditions.

Management estimates the allowance balance using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level, or term as well as for changes in environmental conditions, such as the political, legal, and regulatory environment, technology and consumer preferences. Historical loss information is also adjusted for reasonable and supportable changes in national and local economic conditions, such as consumer loans 90 days past due and commercial bankruptcies. Economic conditions are forecast as "current conditions" over the forecast period. Forecast models were used to validate credit performance during the forecast period. Beyond the reasonable and supportable forecast, the economic expectation reverts to the historical average, which is determined by the weighted average life of each loan pool.

If a loan is individually evaluated a specific allowance is provided, if necessary, so that the loan is reported net, at the fair value of collateral. Interest payments on collateral dependent loans are typically applied to principal unless collectability of the principal amount is reasonably assured, in which case interest is recognized on a cash basis. Loans, or portions thereof, are charged off when deemed uncollectible. The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist.

Determining the Contractual Term

Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a troubled debt restructuring will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by the Company.

Troubled Debt Restructurings (TDRs)

The allowance for credit loss on a TDR is measured using the same method as all other loans held for investment, except when the value of a concession cannot be measured using a method other than the discounted cash flow method. When the value of a concession is measured using the discounted cash flow method, the allowance for credit loss is determined by discounting the expected future cash flows at the original interest rate of the loan.

Allowance for Credit Losses on Off-Balance Sheet Credit Exposures

The Company estimates expected credit losses over the contractual period in which the Company is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. The allowance for credit losses on off-balance sheet credit exposures is adjusted as a provision for credit loss expense. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life. Based on a low likelihood that funding will occur and the Company’s ability to manage the extension of credit to our borrowers, the allowance for credit losses on off-balance sheet credit exposure is not material.

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

The Company reviews its portfolio of debt securities in an unrealized loss position at least quarterly. The Company first assesses whether it intends to sell or it is more-likely-than-not that it will be required to sell the securities before recovery of the amortized cost basis. If either of these criteria is met, the securities amortized cost basis is written down to fair value as a current period expense. If either of the above criteria is not met, the Company evaluates whether the decline in fair value is the result of credit losses or other factors. In making this assessment, the Company considers, among other things, the performance of any underlying collateral and adverse conditions specifically related to the security. At December 31, 2022 and December 31, 2021 approximately 98% of the available for sale debt securities held by the Company were issued by the U.S. Treasury, or U.S. government-sponsored entities and agencies.

The Company does not consider the unrealized loss position of these securities to be the result of credit factors, because the decline in fair value is attributable to changes in interest rates and illiquidity, and not credit quality, and the Company does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery. Therefore, the Company has not recorded an allowance for credit losses against its debt securities portfolio, as the credit risk is not material.

PPP Fee Income Policy

The Paycheck Protection Program (“PPP”), established as part of the Coronavirus Aid, Relief and Economic Security (“CARES”) Act, provided that the Small Business Administration ("SBA") would pay processing fees of up to 5% to lenders based on the volume of the PPP loans disbursed. The fee was based on the balance of each PPP loan outstanding at the time of full disbursement. The Company received processing fees from the SBA of $23.8 million in 2021 and $30.2 million in 2020. The unamortized balance of these fees on each loan is reported on the Company's consolidated balance sheet as part of the loan balance to which it relates and is recognized over the remaining life of the loan as an adjustment of yield. The unamortized balances of these fees was $0 and $2.0 million for the year ended December 31, 2022 and 2021, respectively.

Nonaccrual Policy

A loan is placed on nonaccrual status when, in the opinion of management, the future collectability of both interest and principal is not probable. When interest accrual is discontinued, all unpaid accrued interest is reversed. Interest income is recognized on certain of these loans on a cash basis if the full collection of the remaining principal balance is reasonably expected. Otherwise, interest income is not recognized until the principal balance is fully collected.

The Company does not accrue interest on (1) any loan upon which a default of principal or interest has existed for a period of 90 days or over unless the collateral margin or guarantor support are such that full collection of principal and interest are not in doubt, and an orderly plan for collection is in process; and (2) any other loan for which it is expected full collection of principal and interest is not probable.

A nonaccrual loan may be restored to an accrual status when none of its principal and interest are past due and unpaid or otherwise becomes well secured and in the process of collection and when prospects for collection of future contractual payments are no longer in doubt. With the exception of a formal debt forgiveness agreement, no loan which has had principal charged-off shall be restored to accrual status unless the charged-off principal has been recovered.

Premises and Equipment

Premises and equipment are stated at cost, less accumulated depreciation. Depreciation is charged to operating expense and is computed using the straight-line method over the estimated useful lives of the assets. Maintenance and repairs are charged to expense as incurred while improvements are capitalized. Premises and equipment is tested for impairment if events or changes in circumstances occur that indicate that the carrying amount of any premises and equipment may not be recoverable. Impairment losses are measured by comparing the fair values of the premises and equipment with their recorded amounts. Premises that are identified to be sold are transferred to other real estate owned at the lower of their carrying amounts or their fair values less estimated costs to sell. Any losses on premises identified to be sold are charged to operating expense. When premises and equipment are transferred to other real estate owned, sold, or otherwise retired, the cost and applicable accumulated depreciation are removed from the respective accounts and any resulting gains or losses are reported in the consolidated statement of comprehensive income. Construction in progress includes all the costs of construction associated with the building of fixed long-term assets and is included in premises and equipment, net as an asset. When construction is completed, the asset is reclassified as a building or a leasehold improvement and depreciated over its applicable useful life.

Leases

Certain operating leases are included as right of use lease assets in accrued interest receivable and other assets on the consolidated balance sheet and a related lease liability is included in accrued interest payable and other liabilities on the consolidated balance sheet. Right of use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. The lease liability is measured as the present value of the unpaid lease payments, and the right of use assets value is derived from the calculation of the lease liability. To calculate the discount rate for each lease, the Company uses the rate implicit in the lease if available, otherwise an appropriate Federal Home Loan Bank ("FHLB") advance borrowing rate is used that correlates with the term of the lease.

Other Real Estate Owned

Other real estate owned ("OREO") consists of properties acquired through foreclosure proceedings or acceptance of a deed in lieu of foreclosure, and premises held for sale. These properties are carried at the lower of the book values of the related loans or fair values based upon appraisals, less estimated costs to sell. Losses arising at the time of reclassification of such properties from loans to OREO are charged directly to the allowance for credit losses. Any losses on premises identified to be sold are charged to operating expense at the time of transfer from premises to OREO. Losses from declines in value of the properties subsequent to classification as OREO are charged to operating expense. Revenues and expenses for OREO property are included in the consolidated statement of comprehensive income for the period in which they occur. Gross rental income for OREO is included in other non-interest income. The expenses of operating or holding OREO property are included in noninterest expense.

Intangible Assets and Goodwill

Core deposit intangibles are amortized on a straight-line basis over the estimated useful lives of seven to ten years and customer relationship intangibles are amortized on a straight-line basis over the estimated useful life of three to eighteen years. Goodwill is not amortized but is evaluated at a reporting unit level at least annually for impairment, or more frequently if other indicators of impairment are present. At least annually in the fourth quarter, intangible assets are evaluated for possible impairment. Impairment losses are measured by comparing the fair values of the intangible assets with their recorded amounts. Any impairment losses are reported in the consolidated statement of comprehensive income.

Advertising Costs

Advertising costs are expensed as incurred. Advertising costs for the year ended December 31, 2022 were $3.0 million. Advertising costs for the years ended December 31, 2021 and 2020 were $3.0 million and $3.3 million, respectively.

Stock-based Compensation

The Company recognizes stock-based compensation as compensation expense in the consolidated statement of comprehensive income based on the fair value of the Company’s stock options on the measurement date, which, for the Company, is the date of the grant. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model and is based on certain assumptions including risk-free rate of return, dividend yield, stock price volatility and the expected term. The fair value of each option is expensed over its vesting period.

Income Taxes

The Company files a consolidated income tax return with its subsidiaries. Federal and state income tax expense or benefit has been allocated to subsidiaries on a separate return basis. Deferred taxes are recognized under the balance sheet method based upon the future tax consequences of temporary differences between the carrying amounts and tax basis of assets and liabilities, using the tax rates expected to apply to taxable income in the periods when the related temporary differences are expected to be realized. Realization of deferred tax assets is dependent upon the generation of a sufficient level of future taxable income and recoverable taxes paid in prior years. Although realization is not assured, management believes it is more likely than not that all of the deferred tax assets will be realized.

Earnings Per Common Share

Basic earnings per common share is computed by dividing net income, less any preferred dividends requirement, by the weighted average of common shares outstanding. Diluted earnings per common share reflects the potential dilution that could occur if options, convertible securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the Company.

Revenue Recognition

In addition to lending and related activities, the Company offers various services to customers that generate revenue. Contract performance typically occurs in one year or less. Incremental costs of obtaining a contract are expensed when incurred when the amortization period is one year or less.

Sales of real estate

The sale of real estate property is generally recognized, along with any associated gain or loss, when control of the property transfers to the buyer.

Service and transaction fees on depository accounts

Customers often pay certain fees to the bank to access the cash on deposit including certain non-transactional fees such as account maintenance or dormancy fees, and certain transaction-based fees such as non-sufficient funds fees, overdraft, ATM, wire transfer, or foreign exchange fees. Revenue is recognized when the transactions occur or as services are performed over primarily monthly or quarterly periods. Payment is typically received in the period the transactions occur, or in some cases, within 90 days of the service period.

Interchange Fees

Interchange fees, or “swipe” fees, are charges that merchants pay to the processors who, in turn, share that revenue with us and other card-issuing banks for processing electronic payment transactions. Interchange fees represent the portion of the debit card transaction amount that the card issuer retains to compensate it for processing transactions and providing rewards. Interchange fees are settled and recognized on a daily or monthly basis.

Insurance Commissions and Fees

Insurance commissions are received on the sale of insurance products, and revenue is recognized upon the placement date of the insurance policies or when such commissions are received. Payment is normally received within the policy period. In addition to placement, the Company also provides insurance policy related risk management services. Revenue is recognized as these services are provided. Performance-based commissions are recognized when received or earlier when, upon consideration of past results and current condition, the revenue is deemed not probable of reversal.

For accounts billed by BancFirst Insurance Services, Inc., commission revenue is recognized at the later of the billing date or the effective date of the related insurance policies. Commission revenue, for accounts that are directly billed by the insurance company to the insured, is recognized when determinable by BancFirst Insurance Services, Inc., which is generally when such commissions are received.

BancFirst Insurance Services, Inc. also receives contingent commissions from insurance companies as additional incentive for achieving specified premium volume goals and/or loss experience parameters relating to the insurance they place. Contingent commissions from insurance companies are recognized when determinable, which is generally when such commissions are received.

Trust

BancFirst offers trust services and acts as executor, administrator, trustee, transfer agent and in various other fiduciary capacities. There are four basic types of fees that are included in the trust department income. Administrative fees are assessed for managing trust accounts. Shareholder fees are received in connection with holding specific fund share classes. In return for these services, the mutual fund (or its distributor or investment advisor) pay a fee to BancFirst. Oil and gas fees are assessed for management of oil and gas related activities. There are also other types of fees charged on a one time basis such as those related to opening and closing trust accounts. BancFirst records trust fees on a monthly, quarterly or annual basis based on the size of the asset being managed. Fees may be fixed or, where applicable, based on a percentage of transaction size of managed assets. These fees are recorded as revenue at the time the fee is billed, according to the agreement with the customer.

Comprehensive Income

Comprehensive income includes all changes in stockholders’ equity during a period, except those resulting from transactions with stockholders. Besides net income, other components of the Company’s comprehensive income includes the after tax effect of changes in the net unrealized gain/loss on debt securities available for sale. The Company’s policy is to release material stranded tax effects included in accumulated other comprehensive income on a specific identification basis.

Consolidated Statement of Cash Flows

For purposes of the consolidated statement of cash flows, the Company considers cash and due from banks and interest-bearing deposits with banks as cash equivalents.

Recent Accounting Pronouncements

Standards Not Yet Adopted:

In March 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2022-02, “Financial Instruments – Credit Losses (Topic 326).” ASU 2022-02 eliminates the TDR recognition and measurement guidance and, instead, requires that the Company evaluate, based on the accounting for loan modifications, whether the modification represents a new loan or a continuation of an existing loan. The Company has the option to apply a modified retrospective transition method, resulting in a cumulative-effect adjustment to retained earnings when adopted. In addition, the update requires that the Company disclose current-period write-offs by year of origination for financing receivables. The current-period write-off amendment should be applied prospectively. The amendments are effective for annual periods beginning after December 15, 2022, including interim periods within those annual periods. ASU 2022-02 will be effective for the Company on January 1, 2023. The adoption of ASU No. 2022-02 is not expected to have a significant impact on the Company’s consolidated financial statements.
